The purpose of this article is to investigate the impact of competition on the performance of Indian banks. The survey includes banks from both the public and private sectors. The study will collect data for four years, from 2015 to 2019. Dynamic and static panel data are applied to estimate the association between competition and the bank's performance. Profitability and risk-taking are the performance measures used in the study. The study's main findings are that competition does not impact the banks' profitability in India. However, the findings concerning risk-taking are mixed. Therefore, it can be inferred that overall competition does not impact the banks' performance in India. Other measures of performance of the banks could have been used in the study. It is a limitation to use data of four years. Data for a much more extended period could have also been used. This is one of the few papers on the subject. Therefore, its contribution is very significant. The gap in studies on the topic of competition versus performance of the banks is veritably filled by the current study's findings.

Due to recent enhance of safety law and regulations in construction sites, safety inspectors have been more required in construction sites. However, most of them are novice for safety inspection which have not enough experience and skill. Therefore, the novice safety inspector's performance on hazard recognition needs to be improved for effective safety management. The performance of safety inspection is influenced by the inspector's experience and background because the inspection is usually conducted by the inspector's eyes. Therefore, there is a difference in safety inspection performance between novice and experienced safety managers. This study aims to analyze the gap of risk perception between novice and experienced safety managers using quantitative visual data. For this objective, this study conducted eye tracking experiments for novice and experienced group to evaluate cognitive performance of safety risk factors. The results provides the level of safety awareness based on their experience in construction safety. The limitation of this study is a lack of the number of samples used in this study and did not consider the various characteristics of the participants. If these limitations are supplemented in future research, it can be used to develop safety education contents for novice safety managers.

Immediate implant placement (IIP) in fresh extraction sockets exhibits similar survival and success rates to delayed implant placement in healed sockets. Several advantages of IIP involve shortened total treatment time, reduction of the number of invasive surgeries, and subsequent reduction of patient discomfort due to lack of additional surgeries. The major shortcomings in IIP, however, include the inability to obtain early bony support, presence of a gap between the extraction socket and fixture, and the inability to cover the fixture with soft tissue, leading to increased risk of infection and implant loss. When IIP is performed, atraumatic or minimally traumatic extractions, conservation of the septal bone in molars, minimal flap elevation or flapless surgery, bone grafting the gap between the fixture and the extraction socket, and coverage with soft tissue or a membrane must be considered.

Objectives: In spite of the recent increased concern for Asian dust storms, there are few studies concerning how dangerous the general public recognizes these dust storms to be. This study examined the public's perceptions of the risk of the Asian dust storms and also the source of the information concerning the risk. Methods: A telephone interview survey using a standardized questionnaire was done for the adults living in Seoul and its metropolitan area from May 15th, 2003 to May 16th, 2003. The contents of the questionnaire were the sociodemographic characteristics, the perceptions of risk to the Asian dust storms, and the coping strategy of the study participants. Results: The study participants get their information on Asian dust storms mainly from TV newscasts and they have a good knowledge of them. They regard it as one of the most dangerous health risks, along with dioxin. They think that it is associated with allergic rhinitis, conjunctivitis and bronchial asthma, etc. Of the 500 study participants, 201 (40.2%) persons suffered bodily discomforts during the Asian dust storm period. Conclusions: Although there are uncertainties about the health risks of Asian dust storms, the public thinks these dust storms are very dangerous to health in many ways This negative perception will not disappear easily. To fill the gap of the public's perceptions of the risk and the objective evidence of its health effects, more studies about its health effects and the methods to reduce exposure are required.

Purpose : The lipid profile is a major predictive index for cardiovascular disease, but there have only been a few studies conducted on the relationship between lipid ratio and cardiovascular disease risk factors in the Korean population. To address this research gap, we investigated the association between three lipid ratios and cardiovascular disease risk factors among Korean adults. Methods : This study used data from the seventh Korea National Health and Nutrition Examination Survey conducted in 2016. Lipid ratios included triglyceride (TG)/high density lipoprotein cholesterol (HDL), total cholesterol (TC)/HDL, and low density lipoprotein cholesterol (LDL)/HDL. Cardiovascular risk factors included in this research were: systolic blood pressure $(SBP){\geq}140$, diastolic blood pressure $(DBP){\geq}90$, fasting blood sugar $(FBS){\geq}126$, $HbA1c{\geq}6.5$, body mass index $(BMI){\geq}25$, waist circumference (WC) $men{\geq}90$, $women{\geq}85$, and metabolic syndrome (MetS). A complex samples logistic regression test was performed to analyze the association between lipid ratios and cardiovascular disease risk factors. Results : 1) TG/HDL ratio had statistically significant relationships with DBP, FBS, HbA1c, BMI, WC and MetS. 2) TC/HDL ratio was correlated to SBP, DBP, FBS, BMI, WC, and MetS. 3) LDL/HDL ratio had association with BMI, WC, and MetS. Conclusion : We identified significant association between lipid ratios and cardiovascular disease risk factors. The three lipid ratios were particularly strongly associated with BMI, WC, and MetS.

The big gap between efficacy of population level prevention and expectations due to heterogeneity and complexity of cancer etiologic factors calls for selective yet personalized interventions based on effective risk assessment. This paper documents our research protocol aimed at refining and validating a two-stage and web-based cancer risk assessment tool, from a tentative one in use by an ongoing project, capable of identifying individuals at elevated risk for one or more types of the 80% leading cancers in rural China with adequate sensitivity and specificity and featuring low cost, easy application and cultural and technical sensitivity for farmers and village doctors. The protocol adopted a modified population-based case control design using 72, 000 non-patients as controls, 2, 200 cancer patients as cases, and another 600 patients as cases for external validation. Factors taken into account comprised 8 domains including diet and nutrition, risk behaviors, family history, precancerous diseases, related medical procedures, exposure to environment hazards, mood and feelings, physical activities and anthropologic and biologic factors. Modeling stresses explored various methodologies like empirical analysis, logistic regression, neuro-network analysis, decision theory and both internal and external validation using concordance statistics, predictive values, etc..
