RESUMO
Background: The use of mobile phones especially smart phones have become an integral part of everyone’s life leading to addiction. Most of the studies conducted earlier were focused on youngsters. Hence this study was conducted to find out the prevalence of smart phone addiction in the study area.Methods: Community based cross sectional study carried out in Anakaputhur, Tamil Nadu from November 2018 to January 2019. Sample size of 400 was calculated using the formula 4PQ/L2. The respondents were selected by systematic random sampling. Subjects 18 years and above who are using mobile phones were included in the study. Data was analyzed using SPSS 16 version and presented using descriptive and analytical statistics.Results: Out of 405 participants 191 participants were non smart phone users and 214 were smart phone users. Overall prevalence of smart phone addiction was 27.6%. Male respondents were more addicted than the female (OR-1.94, 95%CI: 1.12-3.77, p=0.01). There was a statistically significant association between subjects <45 years of age and smart phone addiction (OR-2.33, 95% CI: 1.31-4.13, p=0.003) compared to older age group. Likewise respondents who were class III (modified BG Prasad Scale) and above were more addicted compared to subjects below class III (OR-2.29, 95% CI: 1.32-3.98, p=0.002).Conclusions: The prevalence of smart phone addiction is high that has to be addressed seriously. This can be tackled by better life style modification, awareness creation and attitudinal changes
RESUMO
Background: Tuberculosis remains a major global health problem with 10.4 million incident cases in 2016. Although Mycobacterium tuberculosis is the causative agent, many environmental factors play a role in disease progression. Several respiratory hazards including smoking and indoor air pollution were suggested to increase the risk of tuberculosis, but only fewer studies has been conducted on the association between ambient air pollution and tuberculosis.Methods: Data on ambient air quality levels (annual mean concentration of particulate matter 2.5 µg/m3) for the year 2016 was collected from the World Health Organization (WHO) data base for 190 countries which comprises of 6 WHO regions. Similarly data on incidence and mortality rate of tuberculosis for the year 2016 was collected for the above countries from the WHO data base. The data were tabulated and statistical analysis was performed using Pearson’s correlation coefficient model to examine the association of annul mean concentration of particulate matter 2.5 with incidence and mortality rates of tuberculosis.Results: Incidence and mortality rates of tuberculosis were found to be increasing with increasing levels of air pollution. It was correlated using scatter plot. Pearson’s correlation coefficient for air pollution level and incidence of tuberculosis was 0.331 (95% CI: 0.435-0.883), (p<0.001), and for tuberculosis mortality was 0.39 (95% CI: 0.525-0.906) (p<0.001).Conclusions: The study suggests there is a significant positive relationship between ambient air pollution level and tuberculosis incidence and mortality rates.
RESUMO
Production of rice--the world's most important crop for ensuring food security and addressing poverty will be defeated as temperatures increase in rice-growing areas with continued climate change. Climate change needs us to look at various alternatives for more drought tolerant and tougher strains and to develop a technique to screen a large number of genotypes for high temperature tolerance. Adapting temperature induction response (TIR) technique 100 rice genotypes were screened for thermotolerance. Significant variation for acquired thermotolerance was observed in 100 rice lines. From the 100 genotypes 30 were exhibits themotolerance to induced high temperature.
RESUMO
Climate change needs us to look at various alternatives for more drought tolerant and tougher strains. Rice (Oryza sativa L.) is the most important food crop of the world; drought stress is a serious limiting factor to rice production and yield stability in rainfed areas. In order to design efficient varieties with virtues of drought tolerance and high yielding ability is necessary. Root system plays an important role under drought conditions. Among all the genotypes NLR 33671 showed highest root length (27.6cm) under moisture stress condition followed by NLR 3010 (24.5cm), NLR 40059 (23.6 cm), TELLAHAMSA (23.5 cm) ,NLR 40049 (23.5), NLR 3098 (23.5) were showed significantly superior mean values than remaining genotypes for most of the root traits included in this study. Therefore, these genotypes can be considered as drought resistance varieties. Whereas NLR 40054 (14.35 cm), BPT 5204 (14.55 cm), NLR 40045 (15 cm) and NLR 30491 (15.19cm) recorded lowest root length these can be consider as susceptible ones. The effects of drought stress on rice productivity were explicitly parameterized and addressed in the present study.
