Attitudes and Perceptions of Medical Undergraduates Towards Mobile Learning (M-learning).

INTRODUCTION: Mobile technology is one of the latest extensions of technological innovations that can be integrated into medical education. With the aid of these devices, students learn faster outside the classroom by having quick access to the internet and easy retrieval of required health related learning resources to keep alongside of recent trend and development. In medicine practice one has to continuously update his/her medical knowledge and mobile learning will serve as a tool for self-directed learning. AIM: To explore the attitudes and perceptions of undergraduate students towards M-learning. MATERIALS AND METHODS: This educational research included 90 third year MBBS students having clinical posting under the Department of Community Medicine from tertiary healthcare institute in Nashik. Students learning approach was studied with the help of pre-validated questionnaire to know whether they have deep or surface approach to learning. M-learning group was formed on mobile social app to supplement conventional teaching-learning. One subject topic (Tuberculosis, Dengue fever/DHF, Hypertension and Diabetes Mellitus etc.) per week was allotted and after conventional teaching on first day of week the learning materials for the topic chosen for that week were uploaded on the group and students could download as well as share their ideas, learning resources, ask doubts and answer questions at least twice weekly through this mobile platform anytime, anywhere. At the end of three months students attitudes and perceptions towards M-learning were studied by pre-validated structured questionnaires. A five point Likert scale was used (5= strongly agree to 1= strongly disagree) for answering each item of all three questionnaires. The score of 60% (90 out of 150) and the score of 75% (30 out of 40) for each item was considered as the measure that indicates whether or not the student had a positive attitude and perceived the importance of M-learning respectively. Utilisation of M-learning was also studied. RESULTS: It was found that 47 (52.2%) students had deep learning approach, 10 (11.1%) students had surface learning approach. An 80% of students had positive attitude towards M-learning and 76.7% students had perceived the importance of M-learning. A 52.2% of students were actively involved in M-learning group for learning purpose. But 57.8% students did not download (at least twice weekly) the shared reference material, 38.9% students never read and/or replied to the questions asked and 60.0% students never asked any doubts/questions related to the discussion. CONCLUSION: Students had positive attitude and perceived the importance of M-learning. But when they were provided with the opportunity, they did not show appreciable M-learning utilization. This could be because, M-learning was not implemented by all departments; also it was not the part of student's regular assessment and probably a lesser study duration.

Trends in Average Living Children at the Time of Terminal Contraception: A Time Series Analysis Over 27 Years Using ARIMA (p, d, q) Nonseasonal Model.

BACKGROUND: India's National Family Welfare Programme is dominated by sterilization, particularly tubectomy. Sterilization, being a terminal method of contraception, decides the final number of children for that couple. Many studies have shown the declining trend in the average number of living children at the time of sterilization over a short period of time. So this study was planned to do time series analysis of the average children at the time of terminal contraception, to do forecasting till 2020 for the same and to compare the rates of change in various subgroups of the population. MATERIALS AND METHODS: Data was preprocessed in MS Access 2007 by creating and running SQL queries. After testing stationarity of every series with augmented Dickey-Fuller test, time series analysis and forecasting was done using best-fit Box-Jenkins ARIMA (p, d, q) nonseasonal model. To compare the rates of change of average children in various subgroups, at sterilization, analysis of covariance (ANCOVA) was applied. RESULTS: Forecasting showed that the replacement level of 2.1 total fertility rate (TFR) will be achieved in 2018 for couples opting for sterilization. The same will be achieved in 2020, 2016, 2018, and 2019 for rural area, urban area, Hindu couples, and Buddhist couples, respectively. It will not be achieved till 2020 in Muslim couples. CONCLUSION: Every stratum of population showed the declining trend. The decline for male children and in rural area was significantly faster than the decline for female children and in urban area, respectively. The decline was not significantly different in Hindu, Muslim, and Buddhist couples.

An epidemiologic study of occupational stress factors in Mumbai police personnel.

INTRODUCTION: Occupational stress is common to each and every organization at various levels of hierarchy. The police organization is no exception to this. Rather policing is widely recognized as more stressful than any other occupation, nature of work, irregular duty hours, and many more factors, which can trigger stress. The present study was done to highlight some of these stressful factors in Mumbai police. MATERIALS AND METHODS: Simple as well as systematic random sampling technique was adopted to get equal representation from each zone as well as region from Mumbai police. Occupational stress index (OSI) questionnaire was prepared, pilot tested, and validated for screening stress. RESULT: We screened 276 policemen for occupational stress. Seventy-three percent of them were in the 30-50 years age group, and most of them (49%) studied up to H.S.C. Ninety-one percent were married and 56% had reported duty hours 12-16 h/day. Seventy-one percent were addicted to any of the substance. After screening we found 73% moderately stressed, whereas 18% highly stressed policemen. Sociodemographic factors which were age group (50-58 years), duration of service in years (>25 years), duration of duty hours (>16 h/day), addiction habits, and number of monthly holidays (no holiday). We found role ambiguity, under participation, role overload, strenuous working condition, and unprofitability as predominant scales in OSI. So prevention as well as management of stress in policemen is the necessity of the current situation. This stress can be managed at organizational level by adopting right techniques, whereas at individual level by habituating right behavior and attitude.
