Adolescents With Food Allergy Health And Social Care Essay

Aim: To develop and formalize the Food Allergy Quality of Life Questionnaire-Teenager Form ( FAQLQ-TF ) in the Dutch linguistic communication. Methods: Ten nutrient allergic striplings ( 13-17 old ages ) were interviewed and generated 166 HRQL points. The most of import points were identified by 51 nutrient allergic striplings utilizing the clinical impact method, ensuing in the FAQLQ-TF incorporating 28 points ( mark scope 1 ‘no damage ‘ to 7 ‘maximal damage ‘ ) . The FAQLQ-TF, the Food Allergy Independent Measure ( FAIM ) and a generic HRQL questionnaire ( CHQ-CF87 ) were sent to 98 nutrient allergic striplings for cross-sectional proof of the FAQLQ-TF. Consequences: Construct cogency was assessed by the correlativity between the FAQLQ-TF and the FAIM ( rho 0.57, P & A ; lt ; 0.001 ) . The FAQLQ-TF had first-class internal consistence ( Cronbach ? 0.92 ) and discriminated between striplings who differed in figure of nutrient allergic reactions ( 1 nutrient allergic reaction vs. & A ; gt ; 2 nutrient allergic reactions, entire FAQLQ-TF mark, 4.3 vs. 3.5 ; p=0.037 ) , but did non know apart between reported anaphylaxis or non. The FAQLQ-TF correlated decrepit with 6 of the 11 CHQ-CF87 graduated tables, showing convergent/discriminant cogency. Decision: The FAQLQ-TF is the first self-administered, disease-specific HRQL questionnaire for nutrient allergic striplings. It has good concept cogency and first-class internal consistence and discriminates between striplings who differ in figure of nutrient allergic reactions. The FAQLQ-TF is short and easy to utilize and may hence be a utile tool in clinical research.Clinical DeductionsThe Food Allergy Quality of Life Questionnaire-Teenager Form ( FAQLQ-TF ) is dependable, valid, short and easy to utilize and therefore a utile tool in clinical research.Capsule sum-upThe FAQLQ-TF is the first self-administered, disease-specific HRQL questionnaire for nutrient allergic striplings. It is dependable and valid and hence a utile tool in clinical research in which HRQL is the result of involvement.Key wordsAdolescents EuroPrevall Food allergic reaction Health-related quality of life AdolescentsAbbreviationsHRQL Health-Related Quality of Life FAQLQ-TF Food Allergy Quality of Life Questionnaire – Adolescent Form FAQLQ-CF Food Allergy Quality of Life Questionnaire – Child Form FAQLQ-PF Food Allergy Quality of Life Questionnaire – Parent Form MI Mean Importance OI Overall Importance FAIM Food Allergy Independent Measure EO Expectation of Outcome IM Independent Measure CHQ-CF87 Children ‘s Health Questionnaire – Child Form AADR Allergen Avoidance and Dietary Restrictions EI Emotional Impact RAE Risk of Accidental Exposure DBPCFC Double-Blind Placebo-Controlled Food ChallengeIntroductionHaving a nutrient allergic reaction can be fatal and striplings are at the highest hazard of decease from nutrient allergic reaction ( 1-3 ) . It is estimated that 2.3 % of striplings are nutrient allergic ( 4 ) . The lone effectual signifier of intervention of nutrient allergic reaction is rigorous turning away of the implicated nutrient ( s ) and proviso of medicines for exigency intervention ( 5 ) . In malice of the high hazard of decease, nutrient allergic striplings really reported societal isolation as the most distressing facet of their disease ( 6 ) . In add-on, some striplings reported depression as a consequence of nutrient allergic reaction and this may take to troubles in school public presentation and leisure activities ( 7 ) . Therefore, nutrient allergic striplings need to be continuously watchful as to what they are eating in legion state of affairss and scenes and, along with the fright of allergic reac tions, this may hold a negative impact on quality of life. At present, no validated self-administered, food-allergy-specific health-related quality of life ( HRQL ) questionnaire exists for usage in striplings. A few surveies have reported that nutrient allergic reaction has a negative impact on HRQL in striplings. However, three restrictions arise when construing these surveies. First, no differentiation was made between striplings and younger kids ( 8-13 ) , whereas HRQL in striplings demands to be addressed individually, because HRQL may be influenced by the phase of neurocognitive and emotional development of an person ( 14 ; 15 ) . Second, HRQL questionnaires were administered to parents therefore mensurating parents ‘ perceptual experiences ( 8-13 ) . However, kids and parents differ in their positions and judgements about quality of life ( 16 ) . Finally, surveies used generic HRQL questionnaires ( 11-13 ; 17 ) or disease-specific questionnaires which have non been validated ( 8 ; 10 ) , whereas generic HRQL questionnaires are n on every bit sensitive as disease-specific HRQL questionnaires ( 18 ) and proof is highly of import in order to find whether the questionnaire is mensurating that portion of quality of life which is determined by the mark upset ( 19 ) . Therefore, we have developed and cross-sectionally validated the first self-administered, food-allergy-specific HRQL questionnaire for striplings, the Food Allergy Quality of Life Questionnaire-Teenager Form ( FAQLQ-TF ) . This questionnaire has been developed as portion of the EuroPrevall undertaking, a European multi-center research undertaking on nutrient allergic reaction. The FAQLQ-TF complements the late developed self-administered Food Allergy Quality of Life Questionnaire-Child Form ( FAQLQ-CF ) for kids aged 8 to 12 old ages ( 20 ) and the parent-administered Food Allergy Quality of Life Questionnaire-Parent Form ( FAQLQ-PF ) for parents of nutrient allergic kids aged 0 to 12 old ages ( 21 ) .MethodParticipants and processDuring point coevals, participants were recruited merely from our outpatient pediatric allergic reaction clinic. Two striplings were approached during a double-blind placebo-controlled nutrient challenge ( DBPCFC ) and, based on patient records, eight strip lings were approached by phone. All approached striplings ( niˆ?10 ) agreed to take part in an interview on the impact of nutrient allergic reaction on their day-to-day life. During point decrease and cross-sectional proof, participants were recruited from our outpatient pediatric allergic reaction clinic ( based on patient records or assignments for DBPCFC ) or were recruited by advertizement in local intelligence documents and through nutrient allergy support organisations ( the Dutch Foundation for Food Allergy and the Dutch Anaphylaxis Network ) . A missive of invitation, the questionnaire and a pre-paid return envelop was sent to suited striplings from our clinic and to striplings who responded to the advertizement. The missive of invitation stressed that engagement was wholly voluntary. When the questionnaire was non returned within a month, the stripling was contacted by phone as a reminder. Adolescents were non paid for their engagement in any phase of questionnaire development or proof. Before cross-sectional proof, the questionnaire was pre-tested in three striplings ( aged 13, 15 and 17 old ages ) . No major jobs emerged during this pre-test. Thereafter, the FAQLQ-TF, the Food Allergy Independent Measure ( FAIM ) and the CHQ-CF87, a generic quality of life questionnaire, were sent by mail to 98 nutrient allergic striplings. Some of them had participated in the point coevals ( 10 % ) or point decrease ( 49 % ) . Descriptive features were asked sing age, sex, type and figure of nutrient allergic reactions, type of symptoms and diagnosing. For the striplings recruited from our clinic, we checked patient records to find whether nutrient allergic reaction had been diagnosed by a DBPCFC. During all phases of questionnaire development and proof, all common nutrient allergic reactions and different types and badnesss of symptoms were represented. The survey was approved by the local medical moralss review committee ( METc 2005/051 ) who deemed that permission from the committee was non required.DevelopmentItem coevals For the development and proof of the FAQLQ-TF, the same methodological analysis was used as for the development and proof of the FAQLQ-CF, which is described in more item elsewhere ( 20 ) . Briefly, possible points for the new questionnaire were generated by questioning 10 nutrient allergic striplings ( aged 13-17 old ages ) . In add-on, literature reappraisal and adept sentiment were consulted. This resulted in an drawn-out point questionnaire of 166 points. Item decrease The drawn-out point questionnaire was sent to a different group of 51 nutrient allergic striplings to place the most of import points by utilizing the clinical impact method ( 22 ; 23 ) . The striplings were asked to bespeak the importance of applicable points utilizing a five-point graduated table. Frequency ( per centum ) was multiplied by average importance ( MI ) , ensuing in the overall importance ( OI ) of each point. The maximum possible OI was 5.0 ( 24 ; 25 ) . Items with the greatest OI were selected for the FAQLQ-TF, except one of any brace of points with an inter-item correlativity & A ; gt ; 0.85 and/or overlapping content ( face cogency ) . The selected points were worded as inquiries holding a seven-point response graduated table runing from ‘not troubled ‘ to ‘extremely troubled ‘ ( 23 ; 25 ) . A psychologist and a linguist reviewed the FAQLQ-TF for lucidity and easiness of usage.Cross-sectional proofConstruct cogency Construct cogency was investigated by computation of correlativity coefficients for the FAQLQ-TF with the Food Allergy Independent Measure ( FAIM ) . This attack has already been successfully implemented to formalize disease-specific HRQL questionnaires ( 9 ; 20 ; 21 ; 25 ) and it is particularly utile in anaphylactic upsets where no nonsubjective measuring of the extent or badness of disease exists ( 26 ) . The FAIM, which was besides used to formalize the FAQLQ-CF ( 20 ) , includes four Expectation of Outcome ( EO ) inquiries and two Independent Measure ( IM ) inquiries. The EO inquiries are based on the sensed outlook of patients of what will go on following exposure which is likely to be a impulsive force of quality of life ( 26 ) . The IM inquiries are based on the same rule and inquire about the sensed figure of nutrients one needs to avoid and sensed impact on societal life. We expected moderate correlativity coefficients ( 0.40-0.60 ) for the FAQLQ-TF with the FAIM. The proof of the FAQLQ-TF was carried out in the Dutch linguistic communication. The English version of the FAQLQ-TF and the FAIM are presented as Figure E1 and Figure E2 in the Online Repository. The Dutch FAQLQ-TF and the FAIM were translated into English by a native English talker and back translated by a native Dutch talker, harmonizing to the guidelines of the World Health Organization ( 27 ) . The original Dutch version was compared with the back translated Dutch version. No of import differences in content or significance of inquiries emerged. Discriminative ability To set up the discriminatory ability of the FAQLQ-TF, we compared the entire FAQLQ-TF mark for striplings who reported anaphylaxis ( i.e. striplings who reported two or more of the undermentioned cardiovascular symptoms ; giddiness, experiencing your bosom round fast, loss of vision, inability to stand, light headedness, prostration, loss of consciousness/passing out ) versus striplings who did non, for striplings who reported many nutrient allergic reactions versus striplings who reported few nutrient allergic reactions, for male childs versus misss ( 28 ) and for striplings who were recruited from our clinic versus striplings who were recruited by advertizement. Dependability The dependability of the FAQLQ-TF was assessed by administrating the questionnaire to 34 striplings on two occasions 10-14 yearss apart. Convergent and discriminant cogency To look into convergent and discriminant cogency, a generic HRQL questionnaire was administered: the Children ‘s Health Questionnaire-Child Form ( CHQ-CF87 ) ( 29 ; 30 ) . This questionnaire is self-administered by striplings and contains 87 points divided into 12 graduated tables. We expected weak correlativity coefficients ( 0.20-0.40 ) for the FAQLQ-TF with the CHQ-CF87.Statistical analysesThe natural FAQLQ-TF and FAIM scores 0 to 6 were recoded as 1 to 7. The entire FAQLQ-TF mark is the average mark of all points with a scope of 1 ‘no damage ‘ to 7 ‘maximal damage ‘ . To measure concept cogency, Spearman ‘s correlativity coefficients were calculated between the FAQLQ-TF and the FAIM. The allotment of the points of FAQLQ-TF into spheres was based on factor analysis ( chief constituent analysis with Varimax rotary motion ) ( 31 ) and face cogency determined by a clinical expert panel ( BMJFdB, JNGOE and AEJD ) ( 14 ; 32 ) . To look into the inter nal consistence of the FAQLQ-TF and the spheres, Cronbach ‘s ? were calculated. An ? greater than 0.70 indicates good internal consistence ( 33 ) . The Mann-Whitney trial was used for mensurating the discriminatory ability of the FAQLQ-TF. The dependability of the FAQLQ-TF was assessed by ciphering the intraclass correlativity coefficient of the repeated FAQLQ-TF measuring ( 34 ) . Finally, convergent and discriminant cogency were assessed by ciphering Spearman ‘s correlativity coefficients between the FAQLQ-TF and the CHQ-CF87 graduated tables. Statistical analyses were performed with SPSS for Windows 14.0 ( SPSS Inc. , Chicago, IL, USA ) .ConsequenceDevelopmentDescriptive features of the striplings involved in the point coevals and point decrease are shown in Table 1. The drawn-out point questionnaire was returned by 46 striplings ( response rate 90 % ) . The OI tonss of all 166 points of the drawn-out point questionnaire ranged from 0.00 to 2.89. The point decrease re sulted in the choice of 28 points ( OI & A ; gt ; 1.37 ) for the FAQLQ-TF ( Table 2 ) .Cross-sectional proofParticipants The questionnaire bundle including the FAQLQ-TF, the FAIM and the CHQ-CF87 were returned by 75 striplings ( response rate 77 % ) . One stripling was excluded because the descriptive features were losing from the questionnaire, ensuing in 74 assessable questionnaires for the cross-sectional proof. Forty-three striplings ( 58 % ) were recruited from our clinic, of which 19 ( 26 % ) had a nutrient allergic reaction confirmed by a DBPCFC. The other striplings from our clinic had a physician-diagnosed nutrient allergic reaction ( skin asshole and/or blood trial ) and the bulk was expecting DBPCFC. All striplings recruited by advertizement ( 42 % ) reported physician-diagnosed nutrient allergic reactions. Descriptive features of the striplings involved in the cross-sectional proof are shown in Table 1. There were no important differences in descriptive features between male childs and misss, between striplings recruited from our clinic and striplings recruited by advertizement or between s triplings with a physician-diagnosed nutrient allergic reaction and striplings with a nutrient allergic reaction diagnosed by DBPCFC. Construct cogency Most points of the FAQLQ-TF correlated significantly with at least one of the FAIM inquiries and with the mean of the FAIM inquiries. Five points did non correlate with any of the FAIM inquiries and were hence excluded from the questionnaire. The validated FAQLQ-TF therefore consists of 23 inquiries. As expected, we found moderate correlativity coefficients between the FAQLQ-TF and the FAIM. The entire FAQLQ-TF mark correlated significantly with the average FAIM ( rho 0.57, P & A ; lt ; 0.001 ) and with the single FAIM inquiries ( Table 3 ) . This important correlativity coefficient was found for striplings with a nutrient allergic reaction diagnosed by DBPCFC and for striplings with a physician-diagnosed nutrient allergic reaction ( entire FAQLQ-TF mark with the average FAIM, rho 0.76, P & A ; lt ; 0.000 and rho 0.52, P & A ; lt ; 0.000, severally ) . These consequences support the concept cogency of the FAQLQ-TF. That is, the FAQLQ-TF steps that portion of quality of life that is a ffected by nutrient allergic reaction. Expectation of Outcome inquiry 3 ( EO3 ) did non correlate with any of the single HRQL points and is therefore improbable to be an appropriate independent step for nutrient allergic reaction in striplings. Therefore, we excluded this inquiry from farther analyses.Sphere construction and internal consistenceThe 23 points of the FAQLQ-TF were subjected to factor analysis ( chief constituent analysis ) , which revealed 5 factors with characteristic root of a square matrixs & A ; gt ; 1. To assistance in the reading of these factors, Varimax rotary motion was performed for 5, 4 and 3 factors. These groupings were reviewed by an adept panel, and based on face cogency the grouping of 3 factors made the most sense. This grouping revealed the undermentioned spheres: Allergen Avoidance and Dietary Restrictions ( AADR ) , Emotional Impact ( EI ) and Risk of Accidental Exposure ( RAE ) . These three factors showed a figure of strong burdens ; all exceed 0 .300, which is regarded as an acceptable standard ( 31 ) . The adept panel allocated 3 points to a more appropriate sphere based on face cogency. The FAQLQ-TF and the spheres had first-class internal consistence with Cronbach ‘s ? transcending 0.70 ( Table 3 ) .Discriminative abilityAdolescents who reported two or more nutrient allergic reactions reported a significantly more impaired HRQL than striplings who reported merely one nutrient allergic reaction ( entire FAQLQ-TF mark 4.3 vs. 3.5 ; p=0.037 ) . There was no important difference in entire FAQLQ-TF mark between striplings who reported anaphylaxis ( cardiovascular symptoms ) and striplings who did non describe anaphylaxis ( 4.5 vs. 4.0 ; p=0.184 ) or between male childs and misss ( 4.0 vs. 4.3 ; p=0.324 ) . Adolescents who were recruited by advertizement reported a significantly more impaired HRQL than striplings recruited from our clinic ( entire FAQLQ-TF mark 4.6 vs. 3.9 ; p=0.015 ) . Dependability The entire FAQLQ-TF mark intraclass correlativity coefficient was 0.98 ( 95 % assurance interval, 0.95-0.99 ) , bespeaking first-class test-retest dependability. Convergent and discriminant cogency The entire FAQLQ-TF mark correlated weakly with 6 of the 11 CHQ-CF87 graduated tables. In add-on, the spheres of the FAQLQ-TF correlated weakly with several CHQ-CF87 graduated tables ( Table 4 ) . This indicates that both questionnaires step constructs that are partially related ( i.e. convergent cogency ) . However, as expected the correlativities are weak and sometimes even absent because the CHQ-CF87 is a generic quality of life questionnaires and hence non every bit sensitive as the disease-specific FAQLQ-TF ( i.e. discriminant cogency ) .DiscussionWe have developed and validated the first health-related quality of life ( HRQL ) questionnaire particular for striplings with nutrient allergic reaction, the Food Allergy Quality of Life Questionnaire-Teenager Form ( FAQLQ-TF ) . We found that the FAQLQ-TF has good concept cogency and first-class internal consistence ( Table 3 ) . In add-on, the FAQLQ-TF discriminates between striplings who differ in figure of nutrient allergic reacti ons. Finally, the FAQLQ-TF showed convergent/discriminant cogency ( Table 4 ) , which supports the demand for a disease-specific quality of life questionnaire for nutrient allergic striplings. It is known that HRQL may be influenced by the current phase of cognitive, societal and emotional development of an person. Therefore, it has been argued that HRQL in striplings should be measured by agencies of a specific instrument ( 14 ; 15 ) . The FAQLQ-TF was specifically designed for nutrient allergic striplings aged 13 to 17 old ages. Age rightness was ensured by bring forthing and including merely points that were regarded as of import by nutrient allergic striplings ( clinical impact method ) . The FAQLQ-TF focal points on the perceptual experiences of the striplings themselves, because the questionnaire is self-administered. Many of the points in this instrument are specific to striplings. An illustration is ‘Carrying an Epipen ‘ . The Epipen issue in nutrient allergic striplings is in harmony with the literature. It has been reported that striplings raise concerns about its size and portability ( 35 ) and sometimes striplings do non transport it based on societal fortunes and sensed hazards ( 36 ) . Despite our age specific attack and the separate development of kid and adolescent questionnaires, it is striking that about two tierces of the adolescent inquiries in the FAQLQ-TF correspond to the kid inquiries in the FAQLQ-CF ( 20 ) . Therefore, although we generated many age specific points, there are seemingly ‘general ‘ nutrient allergic reaction points that are of import in kids and striplings. Furthermore, we found that the three most of import points that impair quality of life were the same in kids and adolescents ( ‘Always be alert as to what you are eating ‘ , ‘The ingredients of a merchandise alteration ‘ , ‘Able to eat fewer merchandises ‘ ) . An unexpected determination was that EO3 ( Chance of deceasing when by chance exposed ) was non correlated with any of the points of the FAQLQ-TF. This may bespeak that fright of deceasing of nutrient allergic reaction is non a driving force of quality of life in striplings, which may be characteristic and specific for striplings. It has been reported that striplings perceived their anaphylaxis as ‘no large trade ‘ ( 35 ) . In add-on, striplings are at the highest hazard of decease from nutrient allergic reaction ( 1-3 ) . This high hazard may be the consequence of underestimate of the badness of nutrient allergic reaction and the belief of striplings that they will non decease from any cause, including their nutrient allergic reaction. In fact, there were no striplings in this survey who reported ‘always ( 100 % opportunity ) ‘ of deceasing when by chance exposed, whereas this was reported by 5 % of kids and 4 % of grownups in other FAQLQ proof surveies ( non shown ) . Although non statistically important, this is a notable observation. The wrong belief of immortality of striplings may ensue in risk-taking behaviour that may increase the hazard of deceasing from a nutrient allergic reaction. Therefore, doctors and other health-care suppliers should be cognizant that underestimate of nutrient allergic symptoms may be of import when reding striplings with nutrient allergic reaction. When comparing the discriminatory consequences of the FAQLQ-TF with the FAQLQ-CF ( 20 ) , two interesting observations emerged. First, there was no important difference in entire FAQLQ-TF mark between striplings who reported anaphylaxis ( cardiovascular symptoms ) and striplings who did non. The same consequence was found in kids ( 20 ) . Second, striplings who were recruited by advertizement reported a significantly more impaired HRQL than striplings recruited from our clinic. This difference was non important in kids, although a tendency was seen ( 20 ) . It may be that striplings see safety and security by being looked after in the clinic, whereas striplings outside the clinic experience more uncertainness and insecurity about their nutrient allergic reaction ( 37 ) . Most striplings recruited from our clinic were known to us for many old ages ( average figure of old ages since first visit 12.5 ( SD 5.4 ) ) . In add-on, it has late been shown that parental trait anxiousness is hig her in parents of kids with a suspected nutrient allergic reaction who refused to take part in a DBPCFC than parents who did take part ( 38 ) . Since it is known that parental anxiousness is related to child anxiousness ( 39 ) , it may be that the striplings in our survey recruited by advertizement have higher degrees of trait anxiousness than striplings recruited from our clinic and may therefore hold more damage in quality of life. This survey may hold some restrictions. First, the proof of the FAQLQ-TF was carried out in the Dutch linguistic communication. The FAQLQ-TF was carefully translated into English utilizing the guidelines of the World Health Organization. The cogency of the English linguistic communication version of this questionnaire is presently being investigated every bit good as versions in several other European linguistic communications. Our experience with the Dutch Vespid Allergy Quality of Life Questionnaire was that the English interlingual rendition validated good ( 25 ) . It is possible, nevertheless, that cultural differences may act upon the ability of our questionnaire to place the most of import points for nutrient allergic patients in different cultural or lingual scenes. Second, patients were recruited at our clinic and by advertizement. These patients may differ from each other, for illustration in footings of degree of information about their nutrient allergic reaction. However, we did non happen important differences in the descriptive features between these groups and other possible differences would non hold adversely influenced the proof process, where a spectrum of badness is good to obtain optimum correlativities. Third, some of the points in this questionnaire are likely to be clip sensitive in the long tally. For illustration, new labelling Torahs could do the labelling points included in this questionnaire obsolete. It is likely that in clip, this questionnaire will necessitate some updating and version. Finally, this study describes merely the cross-sectional proof of the FAQLQ-TF. Currently, the longitudinal proof of the questionnaire is being investigated ( i.e. the capacity of the FAQLQ-TF to mensurate differences in HRQL over clip ) . In drumhead, we have developed and validated the first HRQL questionnaire particular for nutrient allergic striplings, the Food Allergy Quality of Life Questionnaire-Teenager Form ( FAQLQ-TF ) . We found that this questionnaire is valid and dependable and it is short and easy to utilize. The FAQLQ-TF will be therefore a suited questionnaire for clinical research in nutrient allergic striplings in which HRQL is the result of involvement.RecognitionsThis work was funded by the EU through the EuroPrevall undertaking ( FOOD-CT-2005-514000 ) . We would wish to thank Dr. GFEC van Linden new wave lair Heuvell, medical psychologist, and Karel Verbeek, linguist, for reexamining the drawn-out point questionnaire and the FAQLQ-TF and Tina van der Velde for executing the test-retest of the FAQLQ-TF.

Mental Health Case Study

According to The Free Dictionary, mental illness is defined as, â€Å"Any of various psychiatric conditions, usually characterized by impairment of an individual's normal cognitive, emotional, or behavioral functioning, and caused by physiological or psychosocial factors â€Å"(The Free Dictionary, 2007). Mental illness can certainly be a physical illness, but is not as easily diagnosed like a disease such as diabetes. In a disease like diabetes, physicians can run tests to look for certain indicators of the disease in the blood like the levels of blood glucose and hemoglobin A1C. Sometimes physical conditions can cause mental illnesses. Unlike diseases like diabetes, mental health diagnoses’ often rely more on the patient relaying their symptoms to their physician or health care provider. This could not be as accurate because the patient may be unable to distinguish all of their symptoms or they may not think to tell the health care provider every symptom that they are suffering. According to John Grohol PsyD, â€Å"Treating mental illness rarely results in a â€Å"cure,† per se. What it does result in is a person feeling better, getting better, and eventually no longer needing treatment (in most cases). But even then, rarely will a professional say, â€Å"Yes, you’re cured of your depression. †Ã¢â‚¬ (Grohol PsyD, 2009). The deinstitutionalization of the mentally ill began with the introduction of the use of psychotropic drugs for mental health treatment in the 1950’s. It was embraced as a way of saving money because the patients would be able to be treated on an outpatient basis and in theory also be able to function in the world while on medications. This has not been as successful of a plan as originally intended. Crystal Riberio makes this point by stating, â€Å"The programs thought to replace care given in institutions were not nearly adequate. These programs, attempts to place the mentally ill back in society to be helped by the community members, day programs, and medications were not fully implemented to the full extent needed to replace institutions. This process led to an overwhelming number of mentally ill loose in society, becoming criminals due to lack of treatment† (Riberio, 2006). It is important to acknowledge that mental health services are often administered by a patient’s primary care physician. The patient may make tell their primary physician about problems that they are suffering from in order to seek help there first. The primary physician can prescribe anti-depressants for a patient that is suffering from anxiety or depression. They can also run tests to make sure a problem is not organic in nature versus purely mental. If mental health and physical health care are kept separate, a physician could miss a medical diagnoses that could be causing a mental problem. Some of the services that could be needed for the mentally ill are safe places for them to stay that will help protect mentally ill people from themselves if they are that unstable. There is also a need for therapy to help patients learn about their illnesses and how to cope with it. Managed Healthcare poses more challenges to the treatment of mental illness because they often impose more hoops to jump through in order for the patient to get approved coverage. Managed care organizations reduce health care costs of mental health treatments by imposing limits on the amount of care a person can receive. They may also cover the treatments at a lower percentage, making the patient liable for a larger portion of the cost of care. In order to determine what kind of facility a mentally ill person should go to, one would have to be evaluated by a mental health professional. If the person is a danger to themselves or others, it would probably be best to have them admitted to a psychiatric hospital. If they are simply depressed, they may be able to be treated with medicine and therapy. ? References The Free Dictionary . (2007). Medical Dictionary.

Money and banking Assignment Example | Topics and Well Written Essays - 500 words

Money and banking - Assignment Example Conversely, introduction of money market mutual funds constrained deposit to banks since they paid higher money market values. Finally, the introduction of ATMs in the banking sector reduced the cost of transactions, which the banks used to benefit from due to the paper work required (DeYoung). Hence, the consequence of this shift was a reduction in banks fundamental sources of funds. Experts cite adjustable-rate mortgages (ARMs) as a dubious practice that exacerbated the financial crisis. In this case, ARMs enticed borrowers with low credit to enable them borrow against the value of homes. This way, families were able to own homes that were beyond their reach. Consequently, there was an inflation of a new bubble in the housing sector as prices were indicative of families’ inability to pay (Mackaman). Subprime mortgages, like ARMs, contributed to underpaid-workers owning homes that they could not afford to pay. In effect, this led to creditors risk managing the default payments through shadowy techniques that involved bundling, selling, and repackaging debt. With the number of defaulters rising, what followed was a number of foreclosures that were in contrast with the value of debt bundling from banks and saving institutions. In effect, these institutions resulted to liquidity and solvency status that lead to the crisis (Mackman). Strictly put, banks that follow proper lending procedures will ensure that the borrowers are credit worthy and they will not become defaulters, which can make a bank lose money. However, a bank with high nonperforming loans runs the risk of a low capital base to do business and they can run into trouble with financial regulators. In addition, such publicity might result to substantial withdraws from depositors (a run on the bank). 6- Explain the Basel requirements and how banks got around the

Gender Women's studies Essay Example | Topics and Well Written Essays - 3000 words

Gender Women's studies - Essay Example An issues touching on courtship usually reminds us of the relationship leading to marriage without paying attention to issues, which might terminate it before the goal is realized. Notably, courtship is a complex cultural ritual that has been shaped by modernization (Janrt 187). In fact, many things have changed and the people’s way of life has had dramatic shifts. Traditionally, both men and women did not have a choice of their partner as this was an issue left for the parents, thus part of the societal ritual (Clark, Poulin and Kohler 397). The process of courtship was done by the parents without involving the man and woman to get married. In Ethiopia, Men who had reached maturity would ask their parents to arrange for their marriage, because it was the role of the parents to pay the dowry (Fafchamps and Quisumbing 348). The parents then arranged for the marriage, depending on their choice for his/her son or, daughter. Indeed, it was a complex ritual where dowry was paid after the bride had been identified, prior to the actual marriage (Fafchamps and Quisumbing 348). Additionally, the parents were to make all the necessary inquiries to make sure that their child would marry, or get married to families with impeccable background (Fafchamps and Quisumbing 355)). Precisely, this was the only sure way of sustainability of the marriage and a better life. In some communities, even girls ware to be imposed on older men due to parental arrangements, which they could not resist. However, with increase in education, urbanization and HIV/AIDS epidemics, this has changed and relationships are nowadays by choice (Clark, Poulin and Kohler 398). As part of the engagement process for marriage, courtship has recently shifted attention from organized marriage to a situation where the adult person selects a spouse for him/herself (Clark, Poulin and Kohler 398).

Summary - Essay Example It is argued that probability can be used in the game by always betting on the same color.This, according to the author, increases winning chances. When one looses, the article argues that the next bet should be doubled until the next win (Thomson, 2009). The second idea is card counting in casino games where it is argued that keeping track of discarded cards to know what is left increases winning chances. The article goes ahead to discuss the use of probability in lottery and bookie games. In lottery it is claimed that chances of winning and increased by choosing unpopular numbers. Spreading bets between two bookies is also argued to increase chances of success (Thomson, 2009). I do not agree with the author’s idea of spreading bets between bookies in order to increase the chances of winning. According to the author this strategy works because the bets of the two bookies are normally not equal and they try to make the other not to win. I don not agree with this because of the fact that this defensive tactic is rarely used. In as much as players try to prevent the other from not winning, the majority focus on maximizing their success the same way the one who places his or her bet between the bookies does. This therefore means that if the third party plays safe, he has an equal chance of losing and winning and therefore the argument that he has higher winning chances seems invalid in my

Unit 7 Seminar Research Paper Example | Topics and Well Written Essays - 250 words

Unit 7 Seminar - Research Paper Example While validity helps in determining the types of tests to be used and ensure that researchers make use of methods that are ethical and effective, reliability plays a critical role in psychological tests. Reliability ensures that the test is valuable by maintaining consistency of the outcomes. Before locating the most suitable measurement tools, assess what the clients should know very well, can understand and are able to do. Plan the intent and scope of the assessment by considering the expected experiences after the assessment. Put into consideration how and if the assessment method will determine all the dimensions. Format the assessment instrument to make a clear meaning. When there is a change of program estimates associated with a change in items, then program drift occurs across several administrations. If program values show inconsistency than expected because of measurement errors only, then it cannot be assumed that program values are invariant in testing occasions. Therefore, this may limit the use of the item and warrant its removal from the bank of items. Presence of program drift is mostly associated with construction of irrelevant variance that affects the performance on the item. Due to this systematic performance shift for a long time, cases of program drift may have negative consequences on an assessment program and may ultimately affect inference validity generated from the test scores. This is a common challenge in research. I think both have the same weight. This is because they increase accountability in the political realm. These guidelines help in making decision on evaluation methods to use than reducing errors in

Management - Essay Example After that, everybody choose what part of the project that he or she wanted to do. By the second week, the group established a schedule that suited the whole team. The main purpose of this was to meet and discuss further plans in order to meet the course requirements. Also, the structure of the group was balanced, where every person reported to all the other members. This gave the group the advantage of knowing and being up-to-date on what their colleagues were working on. Another advantage that the group had was no task or process conflicts in choosing the film or working on our meeting schedule. The all-channeled structure made it easy for us to communicate with each other. The group also set their goals and expected outcomes from this experience, and then laid down the plan of how to meet them. Our goals for the team were very straightforward when we began our project. Unexpectedly, we had established some SMART goals for the team prior to knowing the full definition. Our specific goal was a time-bound goal. We decided that everyone would do his or her task and submit it by a specific time. The influence style most frequently used in our group was the collaborative approach. We worked together to include everyone in the decision making process and left no group member in the dark. There was never a set position of power because we all worked together in delegating all of our tasks. This influence style was highly effective because it allowed our group to work as a team and not as singular entities. By agreeing on all of our tasks together, we were able to form a strong unbiased opinion. This allowed us to efficiently set goals and maintain a strong work ethic. Through using this process, there were little to no conflicts. The only minor conflict that arose was when we could not find a set date that would allow our schedules to work together; however, we communicated effectively through emails and got together when

Problems with tracking Terrorist financing Research Paper

Problems with tracking Terrorist financing - Research Paper Example Therefore, when terrorists chose to go back to traditional methods of carrying out their financial transactions, like using cash instead of electronic cards or so, it becomes difficult for the authorities to track such activities. Moreover, terrorists have adopted new techniques of helping them carry out their activities without getting suspected. This paper will broadly look into the findings brought forward in a research done by Torrey Carpenter about the difficulties that national government authorities encounter while trying to identify the financiers of terrorists. He will also suggest a possible solution to the identified problem, present various critics that relate to the problem as well as provide a discussion on the implications that the problem pose. There exist many definitions of terrorism depending on an individual’s point of view. According to one theory, it can be considered to be the illegal use of power or aggression against people or properties with intentions of threatening or pressurizing a government or its society to extend particular political or social goals. According to various law enforcements, Torrey discovers they acknowledge that acts of terrorism can either be domestic or international. Under domestic terrorism, the action is based and carried out within a country and is executed by the country’s own citizens without any outer or foreign enforcers. On the other hand, international terrorism, which is usually linked to foreign groups or governments, involve invasion by the foreign terrorists into a target country. Terrorism has no boundaries and, therefore, any nation around the world is vulnerable to it. He acknowledges that the act, whether carried out internationally or locally, requires a lo t of funding, and up to now, the mystery about who funds the terrorists have not been solved. Since it is an act that involves a lot of damages, be it direct or collateral,

Technology developments over the past 30 years have had only positive Essay

Technology developments over the past 30 years have had only positive effects on people's health - Essay Example The aim of man has been to pursue such a goal that is everlasting and beneficent for him and the people to come. Technology that is in fact for the sake of betterment of our lives has â€Å"proven to be the best companion of man† during this epoch (Kincaid, 2004). It all started with the invention of â€Å"cotton gin in 1792†, which proved to be a great turn in human history. People were able to turn from Neolithic mode of living to more improved life style. The pinnacle of the era that started off during the late 15th century matured in the mid 1850s. And it was the beginning of industrial revolution where mass production, and social revolution, took place of intensive farming and symbiotic lifestyle. Thus it can be said that late 20th century was the finality of man to realize that his salvage for the sake of longevity and betterment can only be achieved through technological advancement and (Lakwete, 2005). People devised ways for healthy living through the use of te chnology. Impetus for such a move was from the ailment, problematic and contorted living man has been in, throughout his history. Thus science for the sake of technology for better living has proven to be the answer (Intille, 2004). It has caused a great deal of help in achieving physiological or biogenic need of man. It has been able to provide secure lives to people and thus has been able to revolutionise our society. Attending to the negative side of the use of technology, one can see that the use of technology in for increasing the ways for mass production and better crop yield, has brought along with it great problems that pertain to the â€Å"environmental pollution† and deterioration of the ecological balance. However, it is up will of people to pay heed to these issues. Their whimsical moves have, of course, created problems, and to contain unwanted and extravagant life, man should be mindful to the facts about his environment. (library.thinkquest.org) Past 30 years h ave been very much important since they advancement in technology tends to concentrate during this era. The invention of integrated circuits has caused compact designs and miniature devices, available for the general use of man. The important factor that has emerged during this era is the work and field specialization and their integration for the collective working for the man. People have been able to deduce solutions that are based on two or more separate specialized streams of technology, say, use of medical science and the proposals from athletes, and mechanical engineers to form such a device that may help in overcoming obesity (ScienceDaily.com, 2011). Taking this technological facet we can put forward an example which proves the notion that â€Å"mix of technologies† has literally improved and achieved those blessings of science that were not thought of ever before. The technologies used by physiotherapists, engineering scientists and medical scientists in tandem with each other can prove to be of great use. The gym equipment, today, is used for targeting a special slack in human physiology (Mishra, 2010). â€Å"Machines that are operated manually and with electronic aid can help regulating health† concerns like blood flow, tissues development, and cell physiology. Tread mill is one such example that helps in curtailing the mental constrains and extra physical exertion during typical arduous terrain exercises. Specialized weight equipment that concentrates on specific muscle is in common use (Plowman & Smith, 2008).

Look at the attachments - Essay Example provement of others’ health from the very beginning of my life, and I used to read various topics which are related to health care, public health issues, and the latest medical developments. Though I was not sure as to which stream in health care I would select, I was convinced that I would be in to health care as I grew. In fact, I can claim that this concern for the health of others runs in my family. To illustrate, my cousin has a B-Pharm and is working at Beximco Pharmaceutical in Bangladesh. When I felt for sure that my future lies in pharmacy, I decided to go and observe myself as to how the pharmacy system works. Thus, I reached Bangladesh and worked under my cousin. Evidently, this period helped me learn a lot about pharmacy. As I sifted through the drugs in the pharmacy and disposed the expired ones, I learned a lot about the importance and nobility of the profession. I think it is necessary to mention yet another incident that further strengthened my desire and conviction. When I reached the age of 18, my grandmother fell sick and it was soon found that she was suffering from cancer. As there was no effective medication at that time, she died of the disease. This incident acted as a wake up call in my life. Seeing her pain and suffering, I understood the need to find a cure for the disease. Again, the solution to the question lies in studying pharmacy. Thus, it becomes evident that pharmacy has been my passion. My immediate goal is to join a medical firm as a clinical pharmacist. From my experience and knowledge, I know very well that a clinical pharmacist has various challenging responsibilities including advising physicians on the effects and side effects of drugs and correct use of drugs. In addition, a clinical pharmacist is responsible to coordinate the pharmacy technicians’ duties like preparing, labeling, and delivering different medications and to ensure that the same is done in accordance with local, state and federal laws. Admittedly, in

Electronic Commerce Essay Example for Free

Electronic Commerce Essay Introduction: E-Commerce is basically using the Internet to either buy or sell goods and it has been revolutionizing the way business is controlled. In recent times Internet has evolved so huge it has lead to development of lots of new web based technologies one of them, which is most used, is E-Commerce [1]. Online shopping is an example for the most used forms of e-commerce, which companies like Amazon or eBay offer. E-Commerce in Modern Business: Nowadays businesses that do not have an EC model have started adapting automating all the manual operations overriding it by e-commerce, since every person would want to save time and money, and these 2 factors are very important in a person’s life. Consider a person who wants to purchase a laptop, he does need to go to a store physically to buy it, he can buy it online within minutes, the laptop company would already have an online shopping website, the person can just browse for available laptops which contains all the information regarding the product right from color, weight, configuration, hardware and software’s, best part is he can also change the configuration online as he wants. Few companies offering online shopping are Dell, Apple, Hewlett Packard, Lenovo and many more. EC gives the people the added advantage to compare various products with one-click, they can either buy or sell their products. Usually sometimes people might not find all the brands in one particular store and now since EC has evolved to an extent where most of the brands offer online shopping a person is not limited to a geography and also M-commerce which is basically using wireless devices or handheld devices to do online transactions. M-commerce has been growing exponentially over the years. Smartphones is the new trend, people started creating Apps for their business, which can be accessed through mobiles, everyone can easily use the App on their smartphone to buy food, clothes, book flight/train/bus/cab etc. It is more  like people can buy anything from the device on the go if they have Internet [1]. E-Commerce in Social Media: Social media has really changed the way we communicate it has replaced all the old age types of communications like writing post cards or letters. Internet has a big role in this change; people use social platforms like Messages, Watsapp, Twitter, YouTube or Facebook for communicating. Many people have still have a doubt how would social media increase the sales of a business. It is simple since almost everyone uses some kind of social networking platform for communicating; these platforms really bring awareness, they showcase daily deals as advertisements, people can keep a tab on the latest products releasing from a brand, business use celebrities to endorse their brands, customers can directly interact on these platforms with others and can discuss the plus or minus of a product or a service [2]. So businesses can setup up an advertisement on a website or social platform to promote their product. Feature for a person or business to promote a product or service ranging from 5$ per day to 100$ per day, based on the payment the audience for the advertisements will be higher. Most of the social networking platforms make money through advertisements. LinkedIn one more social platform for professionals where people from various companies meet and greet each other, participate in technical or non-technical discussions, but one feature where e-commerce is involved in LinkedIn is, it offers a premium profile for users in which a person will have access to apply for more number of jobs and recruiters have full access to post a new job, search for people who need a job or who are considering a job change. This way EC has a very important role in social media too. International Barriers for Success of EC: 3 International Barriers to EC which and their role in EC’s success, one of them is no limitation to Geography. In an e-commerce model when the website  offers shipping to not only domestic places but also internationally, it really helps increase the revenue [3]. Consider a product like Cordless Warming Tray, which is available in America but not available in countries like India, so if anyone wants it, buying the product is easy, any person can purchase the item online through Amazon and enter his/her international address for shipping. E-commerce websites also offer an option for faster shipping if the person needs a product immediately for which the person should pay a little more for the shipping costs. Business are now seeing the opportunities in international markets and have started their business setup’s in those countries, like Amazon did in India recently investing 2 Billions dollars and Uber too a cab service business which is based out of America also started its business in India and few other countries. Success of EC can be calculated here by the increase in revenue from international markets. Only few companies are offering this kind of non-limitation to geography like Amazon, Barnes and Noble etc. Organizations that only offer shipping fewer countries include The Limited, J-Crew and few others. Second type of international barrier is language, considering most of them speak English there might be a section of people who do not speak, read or write English. So to offer e-commerce for those people or to those areas/countries e-commerce websites started adapting their software or website in such a way that a user who has no knowledge of English would be able to search for any product he wants without the need to type in English, he would be able to do it in his own mother tongue and the price of the product is shown in various currencies which would help buyers to easily compare the price. In this type of barrier the number of users base for each company increases which ultimately increases the revenue too. Since now EC model would not only have customers from places who speak, read or write English but also from places where they can use their local language to buy or sell goods, this is very healthy in the EC model. Third type of barrier is for a successful EC model is Legal battle and Infrastructure, as we talked about no limitations to geography and language, so when a company sets up a EC model in different countries the first and foremost thing they will need to comply with is the legal rules of that particular country. Following the rules and regulations legally would really help a company offering EC to run their business smoothly without any issues or hiccups. There have been lots of issues for few companies offering EC in various countries, consider Facebook which is a most used social platform all over the world had to fight for legality issues in few countries since people’s information was visible for everyone. One more example would be Google Earth, which faced a lot of criticism and legal issues and is now banned in India, since it was very helpful for some organizations, which are under the radar of military forces. There are success stories like Amazon, EBay and many more who have been successfully doing their business in different countries. These companies have setup their websites domain separately for each country. Like www.amazon.com is used globally, www.amazon.au is used in Australia, www.amazon.in is used in India, these sites have their own infrastructure setup to control the load of users. Since EC systems should be available 24*7 for them to gain the users reliability and confidence also because users are all across the globe they cannot afford to lose business, they need to have their website up and running all the time. To establish that they need to have heavy configurations, storage and network bandwidths and a team of technical experts who would have the capability to stop hackers from attacking their websites and access risk management techniques well before anything unusual happens. To sum up EC has been growing and will be growing exponentially in today’s and tomorrow’s business, since the ease of doing business has become very easy and as discussed time and money are important which can be saved from EC. Social media the main way of communicating with each other has also benefited from EC in a big way, since billions of users use this platform the revenue generated from the social media advertisements has made some of the start up companies like Google and Facebook to grow from a small scale companies to one of the biggest branded company and revenue generating companies all over the world. The international barriers have also as discussed added up to the success of EC. There might be limitations to EC like security issues and protecting the website or software from hackers but  it all depends on the organization on who attentive they are, how good their staff is in preventing such kind of attacks from happening.

National Integration in Pakistan

National Integration in Pakistan To combine and bring together all the people of a country is known as national integration. It is a feeling which combines all the people irrespective of their colour, race, caste, region and religion etc. It is the only force with the help of which all types of people live together peacefully and considering themselves the members of single whole. 1 THE STATE OF NATIONAL INTEGRATION IN PAKISTAN Pakistan is facing the problem of national integration since its creation. The lack of national integration is a big problem. Owing to the absence of national integration Pakistan has been pushed to cruel circle. It has made Pakistan a sorry state of affairs, and has made Pakistan the centre of terrorist activities. Due to this problem Pakistan has become an instable and vulnerable state and a total breakdown of state machinery. This was not the problem at first. Pakistan was the result of integration on the basis of Islam. Unfortunately after the death of Quaid-e-Azam the country was isolated. National integration faced too many problems. At this rate, income inequalities, social injustice, political blow and other evils raised their heads. All of these made national integration weak and fragile. There is lack of consensus on important national issues in Pakistan. For that reason the provinces hate each other. The Punjab is being accused by the rest of three provinces i.e. Sindh, Kh yber Pukhtunkhwa and Baluchistan for exploiting their resources and not paying there just share. Sindh, Baluchistan, and Khyber Pukhtunkhwa are against the construction of Kala Bagh dame while Punjab wants to construct it. On the issue of NFC award the three provinces having the same reservation from Punjab. There are too much hurdles and difficulties in the way of national integration of Pakistan. It is necessary to vanish the sentiments of regionalism or provincialism languisticism or communalism etc. Some of the important reasons of the failure of national integration of Pakistan are as below: CRISIS OF LEADERSHIP After the death of Quaid-e-Azam there was hardly any leader upon whom the nation could be united. Every leader prefers his personal interest rather than national interest. They built up economic assets on illegal means. Thus they exploited the national purse on the coast of national interest and promoted personal interests. Therefore national integration remained weak and fragile.2 ECONOMIC DISPARITIES There is a big gap between rich and poor. The system of Pakistan has been structured such that the gulf between poor and rich become widen with the every passing day. Rich become richer and the poor become poorer and poorer. It strengthens the upper and privileged class of society. It never cares of the lower class of the society. Thus the economic inequalities led towards the weakness of the national integration.3 PROVINCIAL BIASES AND SOCIAL INJUSTICE Beside the lack of social justice and provincial biases are posing a threat to the basic existence of the country. It leads towards the destabilization of the state and shaking the basis of national integration of the country. The smaller provinces have developed the sense of deprivation. They think that they have been deprived of their just share in the national exchequer and of their just royalty. It has developed the age-old animosities among the provinces. Social justice is the only solution of national integration in Pakistan. The water dispute existed among the provinces. It has posed a major threat to national integration. The provinces have objections on the construction of Kala Bagh dam which has detracted the confidence and unity of the country. Likewise the dispute over NFC (National Finance Commission) award also posing serious threats to national integration. The provinces dont agree on the formula in which the resources are to be divided on the basis of population. This creates great hurdles in the way of national integration of Pakistan. The sense of regionalism has been fuelled by the lack of socio economic justice in the country. Regionalism has divided the whole nation into small and paltry classes. It has created fractions, groups, sects working for their vested interests. Jeye Sindh, Baluch Liberation Front and Baluch liberation army are struggling for the secession from federation. So the question of national integration remain unaddressed and at low priority. There is a trend of promoting personal interest, class interest, group interest and faction and regional interest instead national interests. Almost all parties are talking about Sindhies, Baluchies, Pukhtoons, and Punjabies and other small groups. There is no talk about Pakistan. This politics of regionalism has widened the gulf between different sections of the society. It has shaken the basis of national integration of Pakistan.4 MILITARY INTERVENTION Military intervention has weakened the basis of national integration. During military rule the small provinces has been deprived of there just share. East Pakistan seceded during military rule. The military regime failed to promote the sense of ones in the two wings of Pakistan.5 Baluchistan issue also emerged during military rule. POLITICAL INSTABILITY Political stability is the most important prerequisite for strengthening the national integration. Unfortunately Pakistan is lacking this requirement since very long. The political instability has widened the gulf between the ruling class and the ruled class. It has distorted the picture of Pakistan and made it retrogressive in all spheres. Political instability has posed a big threat to national unity and integrity. Lack of unity and integration has pushed behind the objectives for which Pakistan was created. It has also rhythm of national progress. As a result the nation has become hallow from within in terms of national integration.6 LANGUAGE PROBLEM Pakistani is a plural society. There are living many linguistic groups which is problem. Some time it poses serious threats for the geographical integrity of the state. Pakistan lost its eastern wing owing to many problem of which the language problem was one of the important problem. In todays Pakistan the difference of language is still a problem in the way of national integration of state. It is very much important for Pakistan to have a language policy which is helpful for the promotion of all languages equally. The current policy has created a sense among the small linguistic groups that the government is only promoting Urdu at the coast of regional languages. All the provinces have been divided into more than one linguistic group which contributing to the instability of country.7 MEDIA Media is a source of information and education. It is the most effective mean of change and information. Media is expected to play a positive role in image building of the state. It is the responsibility of media to promote national interest and national integration. In a democratic society the role of media is to be of a watchdog. It is the need of the time that our media should strive for building of soft and positive image of the state.8 Media is the link between the people of a country which propagate the news throughout the country and world by means of electronic devices known as electronic media i.e. radio, TV, net etc and by the means of print media i.e. newspapers, journals, and magazines etc. Media is the most effective source of communication. It enriches the people knowledge about the right and wrong. On the one hand media is breaking false news without proper investigation, yet on the other hand it inform us about the realities.9 POWER OF MEDIA Media is a link between people and societies. Without media they would have been isolated. In the current century media has very much powerful. With the help of media we came to know about the happenings around the world. It unveils the truth and injustice done to people. It rules over the mind of the people. Media educate the people and moulds their opinion, making and toppling the governments makes a hero a villain and a villain a hero. It changes the life style, thinking, culture and tradition of a society. Power of media can be judged through its role as a source of information, education and entertainment. It has changed the world into a global village.10 ROLE OF MEDIA IN NATIONAL INTEGRATION Pakistani media is playing very irresponsible role. Talk shows and political debates dont consider themselves subject to limits. In debates the participants using abusive language against each other. The anchor persons are fuelling the arguments and counter arguments. They dont care for the fact that what type of image they are going to develop publically. What the people will think about them. This trend is conveying a very negative massage inside and outside of the country. Media as opinion maker models the opinion of the people. These talk shows are creating prejudice among the workers of different political parties. And in some cases they get violent against each other.11 In the name of freedom of press media, some time crossing the limits. There is a race among the different channels for breaking news which led to a fierce situation. They are using negative tools for increasing the number of viewership.12 Media has to play a positive and productive role in a society. Education is one of the important factors in promoting national integration. On the same lines media has a very affective role in educating the society. The use of media especially of internet has a lot of contribution in educating society. It is the responsibility of media to unveil the true picture of society. But unfortunately most of the press is prejudice. They are propagating the distorted picture of reality as they want. Media should show responsibility. They should show love and affection instead of hate. They should play a constructive role in providing education to the people and show them the real picture of the world as it is. They should not sensitize the issues. Honest coverage is the spirit of journalism. The media can led the society towards betterment if they start factual reporting. These are some of the major flaws in media if these could be addressed justly they can play an active role in national integration. Ibid media persons and press should be devoted and self reliable. They should show great social responsibilities that would. 13 THE ROLE OF MEDIA IN NATIONAL INTEGRATION Media is the reflection of any country. It shows the way of living and behaviour of the people of any country. The way of expressing news, the way the politicians talking, in talk shows and political debates, show the attitude of the people of that country. The media is bound to spread reality and should be careful of its responsibilities. Media should aware the public without influencing their mind negatively the mind of public and make them able to protest in true manner which could result oriented. Mc Combs and Shaw consider the media as, the mass media sets the agenda for political campaigns, influencing public attitudes toward desired issues. Pakistani media is more responsible than any other media of the other countries of the world because Pakistan needs a big change and the media is the powerful source of change. Now-a-days media is easily accessible to all walks of life through various means electronic means and press i.e. TV, radio, mobile, internet, newspapers, journals, m agazines etc. Media is a force which moulding the opinion of the people. Media changes the approach of the people towards different issues which perform very important role in highlighting certain attributes of issues. Guardians of the media, i.e. news editors, play fundamental role in determining the media outline which become public outline after some time.14 With the appearance of new century the press has become independent. There are TV channels which give coverage to the issues around the country in Pakistan. Media has a lot of contribution in educating the public about issues, but unfortunately media has badly failed in changing the behaviour of the people towards many issues. Media broadcast issues in a way that it boost people instantaneously just after the news report while the people dont know that what they should do in that particular scenario and who they can play a constructive role. Media has to discourage strongly such type of negative approach of the general mass. Demonstrations and protests are good to build up pressure towards solution of any problem but there should be in a right way to demonstrate which should result oriented. With every passing day the reputation of Pakistani media has corrupted owing to its failure in systematically comprehending affairs. Instead of spreading true root cause of issues, media is just adding wordings over the issue and crisis. The coverage of political issues by our media is heavily episodic rather than subjective. There is a number of political talk shows on different TV channels in Pakistan. No programme out of these having an ending or concluding words that could be helpful for people to understand that what will be the possible solution to the problems facing by them. Every program discusses the one and the same issue with different names. Somewhere it is Capital Talk, somewhere it is Aaj Kamran Khan ki sath, To the Point, Kal Tak, Ikhtilaf, Jarga, Likin, etc etc. But no programme has a fruit full ending. There is no difference of information and viewpoint of different political figures. There is no ray of hope regarding the solution of any problem. No politician can g ive remedy nor they coming to the point of solution.15 Constitution of Pakistan gives fundamental rights to citizens. But media does not give importance to it. Instead they are interested in sensitization of issues and news. They are broadcasting such news where they can found something where fundamental rights of citizens are violated.16 Being the powerful pillar of the state media has to save the country form sudden slippage. Media is independent for a long time but it could not show positive role in changing the rebellious attitude of the people. Pakistani media should represent this country with immense care because this country is not only important for Islamic world but for the peace of the world as well. Media should be very much careful while representing this country in the globe and guiding the people of this country to bring out this country form the problems surrounding it. It is the responsibility of media to show the real picture of Pakistani nation to the world, its thinking on the global issues. It represents the culture of Pakistan. Thus media is on the most responsible position. It has to tell the world about Islam and Pakistan and the implications of Islam on Pakistan. Majority of the channels are highly politicised while they should for Islamic norms and values. Some of the channels are religious w hile some are representing secular group. These are representing Pakistan from two different perspectives. This type of media, with two totally different angles widening cultural gap in Pakistan which ultimately results in creating two rival groups in Pakistan. Our media showing the world two different cultures and directing the people to divide into two groups, with one fundamental thoughts and other secular thoughts. 17 For promoting a peaceful and balanced society it is important for all media channels to represent the real culture neither of Pakistan which is neither extremist nor vice versa. Francis Fukuyama, (1995) says that, A thriving civil society depends on a peoples habits, customs, and ethics- attributes that can be shaped only indirectly through conscious political action and must otherwise be nourished through the increased awareness and respect for culture. Unfortunately in Pakistan we are lacking a free and transparent political system, but we have an independent media. Media is more powerful than political parties. Hence media can play an important role in moulding the fate of society towards betterment. Pakistani culture is one and the same and that is Islamic. By dividing it into two divergent cultures creates democratic problems for our society. Media can bridge both the gulf which has been created by one way or other since the creation of Pakistan by playing positive and sensitive role. Some of the already existing groups are distorting the picture of Pakistan by developing false picture of Pakistan and Islam. To minimize the influence of such groups all Pakistani media should represent the true picture of Islam and Pakistan. The entire news and drama channels should adopt national dress symbols of Pakistan which at the same time is Pakistani and Islamic. Unfortunately models, actors, reporter and anchors of media channels follow such a way of speaking, negotiating and apparels which are not true picture of Pakistan and Islam. In a nutshell we can say that media should enhance its role in educating the people that they may be able to participate sensibly to influence the mess. Furthermore media have to build up its status among the society by touching the hidden bonds of society i.e. its culture. Though there are varieties of cultures in our society but all of them surrender to a common culture of Islam. Media has to communicate with the people of society as its part. Tariq Alvi says, à ¢Ã¢â€š ¬Ã‚ ¦..Stress the importance of culture, which may vary even within a country, in negotiating any complex deal you need to understand the values of the people you are dealing with, even if you do not accept their values yourselfà ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦... Therefore media should be very much carful about the culture of Pakistan to integrate the people of Pakistan towards prosperity and development while living within Islamic boundaries.18 Media is being considered as the fourth pillar of the state. In this regard it is expected that it may play a very active role in promoting national integration especially our plural and heterogeneous and divergent society. But unfortunately it has been observed the so called independent media has created violence and hatred on many occasions. Recently Muttahidda Quami Movements leader Altaf Hussain and Pakistan Peoples Party leader Zulfiqar Mirzas speeches has been widely reported in our media which resulted in hundreds of mass killing in Karachi. Likewise medias strong campaign for Lal Masjid operation in 2007 had promoted extremist to kill thousands of soldiers and civilians in target killing and suicide attacks.19 Our media provides us entertainment in forms of Dramas, songs and movies and some funny programmes as hum sub umeed se hain etc. All these are surrounded by romance, love affairs, violence, glamour, big cars, big houses and a clash of poor and rich. All these in no way reflect our culture or represent our culture and civilization. Hardly we can see a programme with a positive and moral result in the democratization of our young generation.20 All these provided to us by media, are responsible for disaster and anarchy in our society. Media has badly failed in providing us role models that could unite our divergent society.21 Medias interest is market drivers and for the sake of rating. It can even compromise on national integration. The supporters of this media argues that media is beating the triumphant Aman ke Asha, which will stop the flow of water towards Pakistan. They projecting the marriage ceremony of Shoib and Sania Mirza, telecasting Altaf Hussains singing, the hatred remarks of Zulfiqar Mirza are breaking news for them for increasing rating and number of viewership. In this scenario how one can expect from media that they will promote national integration rather they are causing disintegration.22 The most recent example of rating is Malalas issue which have been given undue coverage. tens of children die almost every day in drone attacks no channel roused voice for any one of them. It makes the people to think who are being suffered that are they not been given that much projection and thus finally they came on violence against state and all other players of the game. This trend finally led towards destruction of national integration. Before the attack on Malala the media gave very unfair projection to Sharmin Obaid Channaoye. She has made a movie with the name of, Face Saving. In this she had highlighted an issue in which the husbands threw acid on the faces of females. In this issue she has given very negative picture of Pakistani society. She has represented the people brutal, merciless and cruel. She had used the innocent women for her movie. According to print media reports the women who was used for this purpose was not given her wage and neither was given medical treat ment. For her this alleged movie she was prised in Europe and USA and awarded with Oscar Award because she presented a highly exaggeratedly negative picture of Pakistan. Pakistani media given that lady very high projection and presented her as heroin of Pakistan. This kind of reporting and projection is very negatively impacting the image of Pakistan abroad. Media is selling negative news hypes. Media will never make breaking news of a positive development in the violence turned tribal area. Professor Inam Ullah of department of Journalism university of Peshawar says, If you tell any channel that 20 girls got admission in a school in Mohmand Agency no channel will broad cast this news because there is no sensitization in this news and channels dont take interest in such news. On the other hand if you told them that a school has been blown up in the same place or any other area then switch on your TV and tune any channel you will see that all channels are broad casting that news with any investigation and conformation. This is the interest of media. They are sensitizing the issues creating thrill. They are in race and competition. They dont care for national integration or any other positive activity. They just want to break the news before any other news channel breaks it.23 By promoting news with hype is just for the increase of viewers and earn maximum money by commercial advertisement. The people are also responsible for this trend of media. Media is selling what the people want to buy. It is now a business not a source of education or information. People like Indian movies, songs and programmes. TV channels broadcasting these things for increasing the number of viewership. If a channel even tries to telecast a debate on national integration the people dont like to watch it. According to this school of thought if media does not broad caste the hatred of the politician they have in their hearts they wont be able to do justice to themselves.24 Another irony is that media does not give equal coverage to each political party. They are broad casting a five hours press conference of Altaf Hussain directly from England while the next day they dont give 5 minutes time to another political party. They dont publish the manifesto some parties while giving coverage to the minute things of other political party. (amir jamati Islami sayed munawar Hassan interview with Wajahat Saeed Khan, Ajj TV talk show Ikhtilaf on Nov 2, 2012). This trend of media is damaging for national integration of our country. TV channels have no concern to play positive role to bridge the gap which has been created the absence of good governance in different section of society. They are just interested in sensitive news and want to break such news which can attract more and more viewers.25 Almost all TV shows are made for urban consumerist population a soft victim for advertisers. These shows are full of sumptuous cooking; ingredients are the product so of huge companies and plays in which families Banarasi Saris, gold jewellery, and full makeup in their daily lives at houses.26 When the working class are the lower and poor class of a society who are hardly living their lives, watch all these things a desire came in their heart for such lavish life. But their pocket does not allow them to afford. They get frustrated and thus a feeling of hate emerges inside them. they turned severely against the upper and privileged class of society and thus against the whole system. This finally poses many threats to national integration. This mindset is responsible for so many social evils. TV commercials also playing the same role. They ate are showing the products of big companies which are practically out of the range of the society at large. In these commercials the life is imaginary which can be seen only on TV screen but not possible in practical life. The culture is being represented neither in dramas and movies nor in TV commercials.27 With so much social estrangement between haves and have-not, can they identify with the country our media depicts? How we can expect them to have patriotic feeling or the right values? the writer of the article wrote her personal experience in such words, I remember a child show in which actress was asked if she would give a massage to children, enthusiastically she replied, khao, peyo aur maze karo,.28 this is the massage normally given by TV anchors and shows. When a child of poor parents receive such massage and then they demanding for such a life where ones concentrate is just upon eating, drinking and enjoyment, and his/her parents could not afford this both parents and child get frustrated and turned against the system. They will try to snatch this luxurious life form those who living it irrespective of the fact that he can live such life or not but at least the upper class should not live it. Instead of a massage could be given to care about the less fortunate, do study better, to be respectful towards their elders, to be honest in their dealing or not to litter and through garbage all over the place. Insight and aspiration for nation building could have been given. But do media persons care? 29 RELIGIOUS PROGRAMMES AND NATIONAL INTEGRATION There are so many so called religious programmes in which religious scholars appear who came on different TV channels and interpret Islam from their own perspective and point of view. They are crazy of popularity, money and modernity. There is a huge gap between the interpretation of modern ulama and the orthodox ulama. There are people who cannot bear either of the opponent group. They turned against each other and especially the followers of orthodox ulama even came on aggression which causes too many problems in our society. Dr Javed Ahmad Ghamdi, Dr Faroop (late) Dr Aamir Laiqat Hussain is among the modern ulam. Orthodox ulama have issued fatwas against them. The death of Dr Farooq is being connected with this opposition of ideas among orthodox and modernists. He was given threats to take his modern ideas back or then get ready for drastic consequences. CONCLUSION Without media neither we can formulate an opinion nor can resolve any problem. Media has the potential of projecting any culture and give a sense of belonging to people belonging to different backgrounds. But unfortunately there are many examples where media could not come up with the expectations of the people. From the above discourse it reveals that media in Pakistan does not deliver according to the needs of the nation. Their more concentration remains on market. How to increase the number of viewership, how to attract advertisers and how to break fresh news before any other do it. In this race and competition they often broadcast false and sensitive news. Media is the most responsible institution of any state. In a state like Pakistan its responsibilities are more sensitive than any other country. Today Pakistan is the focal point of the world. All the countries have interest in Pakistan and thus they analyzing the situation every minute. Being a responsible institution media in Pakistan should avoid sensitizing the news. All those news should not be telecasted which can rise the communal or ethnic crisis. Every day we observe that someone has committed suicide, someone has been killed for being shia or Sunni, a school has blown up in so and so area, target killing are going on in Karachi, a shrine of some famous personality has blown up by terrorists etc, etc. After careful analysis all this type of news are poison for national integration. It weakens the roots of national unity and feeling of oneness. A feeling of hatred emerges in the hearts of people against each other which led towards communal crisis, ethnic crisis, provincialism and regionalism. The media should avoid such type of news and reports. They should give very little coverage to such news and concentrate on positive news that the people may get hopeful for better prospects in future. Different talk shows on different TV channels are creating illusion among the people. The politicians who are supposed to guide the people in difficult times are talking in a highly uncivilized manner in TV programs which does not suite their status. Media should work as a beacon and candle. It can do anything to make hero a villain and a villain a hero. It should lead the nation in a right direction. They should not work as the agent of western media and organization as puppet in their hands as it has been working. It is the need of the day that the intellectuals should discuss this problem seriously. Media is a tool which can be used for positive purposes very fruitfully.

Driverless Metro Train With Obstacle Detector Engineering Essay

Driverless Metro Train With Obstacle Detector Engineering Essay INTRODUCTION This project is designed to understand the technology used in driver less metro train. This technology is the future of the metro train. This train will be equipped with the microcontroller as the CPU, Sensors, Displays, and Motors. These trains will be designed for following the specific path. This microcontroller will be programmed such that door opens and close automatically when the train reaches its station. This microcontroller will be programmed for a specific path so that it knows the distance between two stations. It also opens the door when train reaches the station for a certain time and then closes. Also if the train is following its path and in front of train an obstacle is detected the sensor will sense the obstacle from a safer distance so that the train can be stopped before accident. In this project we are using the same pattern described above. Here we are using AT89S52 microcontroller as a CPU. One stepper motor is used for the train so that it can travel between the stations. Second, motor is used for the door open and close. For displaying the number of station and emergency message we are using 2 line LCD displays. Here the train is designed for ten stations numbered 1 to 10. LCD is used to display the message as station number reached. Also buzzer is used as a sound indicator of emergency alarm and door open. Sensor is used to detect the obstacle in front of the train. When the obstacle is detected the buzzer will sound , all the motors stop, and message will be displayed on the LCD. When the obstacle is removed the train will again start moving on its path. The train equipped with microcontroller controls LCD L293D motor driving IC PIR sensor Buzzer Led LIST OF COMPONENTS 1 IC 8051 MC (AT89S52) 1 2 IC L293D 1 3 Transformer (120 V to 12V) 1 4 Voltage Regulator 7806 1 5 Voltage Regulator 7812 1 6 2 X16 LCD display 1 7 Stepper Motor 2 8 Crystal Oscillator (11.0592 MHz) 2 9 Switch 1 10 LED 1 11 Resistors (1k,10k,8.2k,18 SIP10kÃŽÂ ©)- pack of each 12 Capacitors(22pf,10uf,1mf,10nf) pack of each 13 Diode IN4007 4 14 Buzzer 1 15 Transistor (5474A) 1 16 PIR 1 WORKING OF PROJECT: Driver less metro train project is typically based on microcontroller. Where microcontroller used as a CPU is controlling the entire circuit. The micro IC is programmed to follow the sequence of instruction or interrupts generated during the whole operation. The whole project circuit is divided into different parts so that it is easy to understand and debug. The main parts are Main microcontroller circuit L293D motor driving circuit Power supply circuit LCD circuit PIR sensor circuit These four parts are connected together to make the whole project functional. BLOCK DIAGRAM led POWER SUPPLY MICRO 8051 L293D IC MOTOR SENSOR PIR LCD 2X16 BUZZER CIRCUIT DESIGN (MULTISIM DESIGN, ULTIBOARD DESIGN) POWER SUPPLY For explaining the working of the project firstly we explain the architecture of the power supply. For this project we need the power supply that can convert 120V to 12V and 6 V. the main components used in the power supply are: DC POWER SUPPLLY Transformer (120V to 12V Step down, 0.5Amp) IN4007 diodes connected I bridge shape Voltage regulator 7806 and 7812 Capacitor (1uf,10 nf) Resistor (10 kohm) The 120 volts is step down by 12 volts by transformer. Then this 12V is rectified by the bridge rectifier made up of diodes. This bridge rectifier is used to provide DC voltage. Then the 12V is regulated by 7806 to 6V and 7812 to 12V. 1 micro farad capacitor is used to filter the pulsating DC voltage in order to get the pure DC. Here 6V is given to the microcontroller circuit. Other, 12V is given to the motor driving circuit. Here Voltage regulator is used so that no fluctuation occurs in order to get constant voltage. The LED attaches to check the correctness of power supply. PIR SENSOR PIR stands for Passive infrared sensor which detects the motion of the obstacle in front of the train. Its pin 1 is connected to the VCC, pin 3 connected to the ground and pin 2 is connected to the base 0 of the transistor. The output of the sensor is active high which is given to the base of the transistor. This transistor act like a not gate and convert active high input to active low output of the transistor output. The collector of the transistor is connected to the microcontroller port 3.0. Resistance is connected to the base of the transistor to prevent overflow of the current. The output of the PIR sensor is digital. When PIR sensor senses the obstacle in front of the it sends active low input through transistor to the microcontroller as a interrupt. When microcontroller gets this interrupt the programming in the microcontroller stops all the motor bringing the train to stop. Also the led will glow and buzzer will sound showing the presence of obstacle. LCD MODULE In our project we are using 2 line and 16 digit LCD display. This lcd has 16 pins. It is connected as a parallel port to the microcontroller. Here we are using 14 pins two pins are not being used. Out of these 14 pins, 8 pins are used for data lines to communicate with the microcontroller. These 8 pins are connected to the port 2.0 to port 2.7 of the microcontroller. When the message is to be displayed by the microcontroller it is transferred through these data pins. Here data bit D7 is used for showing the busy message. When D7=1 the LCD is busy and when it is D7=0 than it is not. RW, EN, and RD are connected to the port 3 pins P3.5 to P3.7. EN pin is used to detect the high to low pulse. RS=1 is used for register select that is data register to display data coming from microcontroller and RS=0 command register to get command from microcontroller like clrscr. For data register RS =1 and for command register RS=0. For RW we have R=1 and W=0. VCC pin is connected to 5V power supply, G ND pin is connected to ground. CV pin is connected to potentiometer which is used to adjust the contrast of the LCD. MOTOR DRIVING CIRCUIT The motor driving circuit depends upon the output of the microcontroller. 2 motors are connected to L293D IC. This IC is used separately to drive motor because the microcontroller voltage is low to drive the motors. L293D act as a amplifier for driving the motor. Here the output of the IC is same as the input the difference is just that the input voltage is amplified. Two motors are connected to the output of the IC. This L293D IC can rotate motor in either direction. L293D is connected to the port0 of the microcontroller through pull up resistor. In the staring both the motor are in off state. Each motor has two pins that are connected to the IC. Here instead of using both motor we are using CD tray motor that will act like a gate which will open when it get open command from microcontroller and close with the close command. we are using stepper motor that is a electro-mechanical rotary actuator that converts electrical pulses into unique shaft rotations. This rotation is directly r elated to the number of pulses. This motor can be operated in forward/reverse with controllable speed from a microcontroller through a transistor driver circuit. This stepper motor is a (4 phase) 12 VDC, 150 mA motor that takes 3.6 degrees per step. Phase resistance (Ohms): 75 Â · Current (mA): 150 Â · Phase Inductance (mH): 39 Â · Detent torque (g-cm): 80 Â · Holding Torque (g-cm): 600 Â · Mounting hole space diagonal (in.): 1.73 Â · Mounting hole (in.) 0.11 Â · Shaft diameter (in.): 0.197 Â · Shaft length (in.): 0.43 Â · Motor Diameter (in.): 1.66 Â ·Motor height (in.): 1.35 Â · Weight: 0.55 lbs. BUZZER C:UsersAdminDesktopimages (1).jpg In this project buzzer is used as a alarm indicator. Buzzer has 2 pins its positive is connected to the supply voltage and negative pin is connected to microcontroller at port 1 pin p1.0. Buzzer will sound when it receive 0 from the microcontroller and stop when it receive 1 from P1.0. This buzzer will sound when the train reaches the station and also in case of emergency when obstacle is detected. AT89S52 C:UsersAdminDesktopAT89S52-MICROCONTROLLER-configuration.jpg The AT89S52 is a low-power, high-performance CMOS 8-bit microcontroller with 8K bytes of in-system programmable Flash memory. The device is manufactured using Atmels high-density nonvolatile memory technology and is compatible with the industry-standard 80C51 instruction set and pinout. The on-chip Flash allows the program memory to be reprogrammed in-system or by a conventional nonvolatile memory programmer. By combining a versatile 8-bit CPU with in-system programmable Flash on a monolithic chip, the Atmel AT89S52 is a powerful microcontroller which provides a highly-flexible and cost-effective solution to many embedded control applications. The AT89S52 provides the following standard features: 8K bytes of Flash, 256 bytes of RAM, 32 I/O lines, Watchdog timer, two data pointers, three 16-bit timer/counters, a six-vector two-level interrupt architecture, a full duplex serial port, on-chip oscillator, and clock circuitry. In addition, the AT89S52 is designed with static logic for operation down to zero frequency and supports two software selectable power saving modes. The Idle Mode stops the CPU while allowing the RAM, timer/counters, serial port, and interrupt system to continue functioning. In this microcontroller 11.0592 crystal oscillator is used to produce clock pulses for the microcontroller functioning. These clock pulses are used for R/W cycle. 2 ceramic capacitor of 22pf are used to provide pure pulse to the microcontroller. A combination of resistance 10 kilo ohm and capacitor of 10uf are used to provide reset circuitry. When we provide power to microcontroller it should be reset for some time. The reset time is given by t= 1.1*R*C. This reset circuitry is connected to port 1 reset pin; this circuit can be manually reset using switch which is also connected to the reset pin. Interrupt pin INTO is connected to the output of the transistor which gives active low input as a interrupt. Port 0 is connected to 18 (10 kohm) SIP resistors to provide the external pull up. Port is used for the output to the motor driver circuit. Port 2 is connected to the LCD module. TROUBLESHOOT 1-Care should be taken while choosing the components with proper rating. 2- Power supply should maintain preventing short circuit. 3- Project should be handled with care since IC is delicate. 4- Project circuit should be simple so that it is to debug. 5-Etching and drilling holes should be done carefully. 6-Soldering should be done with proper precaution Advantages 1-Lower expenditure for staff .However, service and security personnel is common in automated systems. 2-Trains can be shorter and instead run more frequently without increasing expenditure for staff. 3-Service frequency can easily be adjusted to meet sudden unexpected demands.. 4-Intruder detection systems can be more effective than humans in stopping trains if someone is on the tracks. 5-Financial savings in both energy and wear-and-tear costs because trains are driven to an optimum specification. FUTURE SCOPE This project will be useful for the metro trains. This is very low cost project that can be help full in operating the train without driver. One can operate the train from remote distance. It will also be beneficial for the developing countries decreasing the cost of labors. Also the station information and emergency will also be displayed to the passengers. It will going to increase the technology trends. This is just a scratch to start this project there is a lot of improvement can be done in this project APPENDIX CODING FOR PROJECT #include void delay(unsigned int); void lcdcmd(unsigned char); void lcddata(unsigned char); void lcdready(); void welcome(); void obstacle(); void station(); void gate(); sfr ldata = 0xA0; sbit rs = P3^7; sbit rw = P3^6; sbit en = P3^5; sbit busy = P2^7; sbit m11 = P0^0; sbit m12 = P0^1; sbit m21 = P0^2; sbit m22 = P0^3; sbit alarm = P1^0; sbit led = P1^1; void ad(void) interrupt 0 { P0 = 0x00; alarm = 0; obstacle(); } void main(void) { IT0 = 0; // Configure interrupt 0 for falling edge on /INT0 (P3.2) EX0 = 1; // Enable EX0 Interrupt EA = 1; // Enable Global Interrupt Flag P0 = 0x00; alarm = 1; led = 1; m11 = m12 = m21 = m22 = 0; lcdcmd(0x38); lcdcmd(0x0E); lcdcmd(0x01); lcdcmd(0x06); lcdcmd(0x81); while(1) { welcome(); station(); lcddata(1); led = 0; gate(); led = 1; m11 = 1; delay(1000); m11 = 0; station(); lcddata(2); led = 0; gate(); led = 1; m11 = 1; delay(1000); m11 = 0; station(); lcddata(3); led = 0; gate(); led = 1; m11 = 1; delay(1000); m11 = 0; station(); lcddata(4); led = 0; gate(); led = 1; m11 = 1; delay(1000); m11 = 0; station(); lcddata(5); led = 0; gate(); led = 1; m11 = 1; delay(1000); m11 = 0; station(); lcddata(6); led = 0; gate(); led = 1; m11 = 1; delay(1000); m11 = 0; station(); lcddata(7); led = 0; gate(); led = 1; m11 = 1; delay(1000); m11 = 0; station(); lcddata(8); led = 0; gate(); led = 1; m11 = 1; delay(1000); m11 = 0; station(); lcddata(9); led = 0; gate(); led = 1; m11 = 1; delay(1000); m11 = 0; station(); lcddata(1); lcddata(0); led = 0 ; gate(); led = 1; } } void gate() { m21 = 1; m22 = 0; delay(200); m21 = m22 = 0; delay(300); m21 = 0; m22 = 1; delay(200); m21 = m22 = 0; } void welcome() { unsigned char proj1[] = Metro Rail; unsigned char z; lcdcmd(0x01); lcdcmd(0x83); for(z = 0; z { lcddata(proj1[z]); } delay(200); } void obstacle() { unsigned char obs1[] = Obstacle; unsigned char obs2[] = Detected; unsigned char z; lcdcmd(0x01); lcdcmd(0x84); for(z = 0; z { lcddata(obs1[z]); } delay(100); lcdcmd(0xC4); for(z = 0; z { lcddata(obs2[z]); } } void station() { unsigned char st[] = Station ; unsigned char z; lcdcmd(0x01); lcdcmd(0x83); for(z = 0; z { lcddata(st[z]); } } void delay(unsigned int itime) { unsigned int i,j; for(i=0;i for(j=0;j } void lcdcmd(unsigned char value) { lcdready(); ldata = value; rs = 0; rw = 0; en = 1; delay(1); en = 0; return; } void lcddata(unsigned char value) { lcdready(); ldata = value; rs = 1; rw = 0; en = 1; delay(1); en = 0; return; } void lcdready() { busy = 1; rs = 0; rw = 1; while(busy == 1) { en = 0; delay(1); en = 1; } return; }
