Attitude and practice regarding Hepatitis B vaccination among medical students in a teaching medical institution in Puducherry
No full textThe incidence of liver diseases associated with hepatitis B virus remains a global public health problem. Medical personnel are the first contact between such patients and health care and medical students are indeed at risk of the same. Present cross-sectional study was undertaken among second year medical undergraduates of MGMC and RI, Puducherry during August 2012, to assess the attitude and practices of medical students towards hepatitis B vaccination (HBV) and find out the vaccination coverage among them. After brief introduction about rationale of the study a pre-tested, self-administered, anonymous questionnaires was distributed. Information regarding background characteristics of participants, Hep-B vaccination coverage and reasons for poor acceptance/compliance were collected. The questionnaires were distributed on a single day in order to avoid sharing of information. Data was analyzed using statistical software using SPSSversion 16.0. Out of total 150 questionnaires circulated, 120 (response rate 80%) were returned (Male 53.3%, Female 46.7%). Among them 21 (17.5%) students had already received three doses of Hep-B vaccination. 22 (18.3%) students didn't receive any dose. Reasons for poor coverage and/or non-compliance of Hep-B vaccination among medical students include forgot to complete the course (43.4%), not a mandatory process in the institution (26.3%), not compulsory for every individual (18.2%), fear of injections (4%) and expensive (5.1%). Coverage of Hep-B vaccination was poor among medical undergraduates in the present study. Concerted efforts should be made to motivate medical students and their family members towards Hep-B vaccination with support from medical college and medical council of India. The admission day can be utilized as an avenue for this initiative
Simulation based Analysis of Transformerless Photovoltaic Inverter Topologies for Reactive Power handling Capability
No full textThis study investigates the reactive power generation capability of the existing transformerless Photovoltaic Inverter Topologies (PVIT) with their conventional switching strategies. The topologies such as H5, families of H6 (H6, H6-I, H6-II, H6-III and H6-IV), HERIC, and clamped topologies (optimized H5, passive clamped H6 and HBZVR) have been selected for analysis. Matlab/Simulink simulation platform is employed for the analysis of PVIT. It has been observed that transformer-less PVIT with their conventional switching strategies are not suitable for reactive power injection. These topologies are generating highly distorted current at zero crossings during the reactive power flow. The improved switching strategies are needed to make these topologies suitable for the reactive power applications without any modification in the structure of the inverter.Accepted author manuscriptPhotovoltaic Materials and DevicesIntelligent Electrical Power Grid
Groundwater potential zonation by Remote Sensing and GIS techniques and its relation to the Groundwater level in the Coastal part of the Arani and Koratalai River Basin, Southern India
No full textGroundwater is being pumped extensively from the coastal part of the Arani and Koratalai River Basin, Tamil Nadu, India for irrigation and water supply to the city of Chennai. The objective of this study is to delineate the groundwater potential zones of this area using Remote Sensing (RS) and Geographic Information System (GIS) techniques. Weighted overlay analysis was used to demarcate the ground- water potential zones. Various thematic layers such as geology, geomorphology, soil, lineament density, drainage density, rainfall and landuse maps were prepared. The geological map was prepared using a Geological Survey of India (GSI) district resource map. Indian Remote Sensing System Linear Imaging Self-scanning Sensor III (IRS-1D LISS III) satellite imagery was used to prepare the geomorphology, soil, lineament density, drainage density, and landuse maps. The final groundwater potential map was prepared by assigning appropriate weightage to different thematic maps and adding them to the final groundwater potential map. The derived groundwater potential map was overlaid with the groundwater level and location of well fields for validation. The map prepared will help in systematic and proper development of groundwater resources in this area to meet the growing water requirements of the city of Chennai.
Resumen
Aguas subterráneas se bombean en gran cantidad desde la parte costera en las cuencas de los ríos Arani, en Tamil Nadu, India, para el riego y el aprovisionamiento de agua a la ciudad de Chennai. El objetivo de este estudio es delinear las zonas potenciales de aguas subterráneas en esta área a través de sistemas de Teledeteción (RS) y de Información Geográfica (GIS). Se hizo un análisis sobrepuesto compensado para demarcar las zonas con posibilidad de tener aguas subterráneas. Se prepararon mapas de uso de la tierra con varios elementos temáticos como geología, geomorfología, terreno, densidad de lineamiento, densi- dad de drenaje y precipitación. El mapa geológico fue preparado a partir del Mapa Distrital de Recursos, del Servicio Geológico de la India (GSI). Fueron utilizadas imágenes satelitales Sensing System Linear Imaging Self-scanning Sensor III (IRS-1D LISS III) para definir la geomorfología, terreno, densidad de lineamientos, densidad de drenaje y mapas de uso del terreno. El mapa final de zonas potenciales de aguas subterráneas se preparó con la superposición apropiada de diferentes mapas temáticos sobre los mapas de aguas subterráneas potenciales. Para la validación apropiada, el mapa derivado se solapó con los de niveles de aguas subterráneas y de zonas de pozos. El mapa preparado ayudará en el desarrollo sistemático y apro- piado de las fuentes hídricas subterráneas en esta área que permita abastecer la creciente demanda de agua de la ciudad de Chennai

No full textBackground: The mental health of medical and paramedical college students is likely to be severely affected by the second wave of COVID-19 pandemics, affecting their learning process. Aim and Objectives: The aim of the study was to assess the prevalence and level of stress, anxiety, and depression of health-care students living in Erode district, and their sleep quality during the second wave of COVID-19 pandemic. Methodology: This is a cross-sectional study and it was conducted via Google Form survey completed by students studying health-care-oriented courses such as MBBS and nursing students in Erode district. Results: A total of 318 students had completed data on demography details, sleep quality by Pittsburgh Sleep Quality Index, and mental health by Depression Anxiety Stress Scales questionnaires. The prevalence of borderline abnormal depression, anxiety, and stress was 25.5%, 25.2%, and 16%, respectively. The prevalence of poor sleep was 45% and overweight and obese students (P = 0.03) had more poor sleep scores than others. Nursing students had significant depression (P = 0. 03), anxiety (P = 0.04), and stress (P = 0.03) score than others. Conclusion: During the second wave of the COVID-19 epidemic, there was a significant rise in the incidence of unpleasant feelings and attitudes among health-care students stationed in COVID treatment hospitals, as well as poor overall sleep quality. We hope that this research will lead to an additional investigation into the mental condition of health-care students during public health emergencies. Furthermore, special emphasis must be devoted to improving the sleep quality of health-care students who are constantly exposed to the current viral pandemic due to their profession
