This study is intended to look into the effect of construction safety supervision system on risk control and reduction. To achieve this, a survey was carried out to 114 companies in construction, ordering, contract and management. The overall findings were as follows. The effect of construction safety supervision system on risk control and reduction showed that factors of supervision system, supervision cost and supervision method had a positive effect on risk control and reduction. And their perception of the introduction of safety supervision system in construction sites according to process showed that there was a difference between them according to the field of ordering, contract and supervision. There was the biggest difference between owner and contractor in double supervision system, but no difference between them in the perception of risk reduction. These results show that all ordering, contract and supervision are positively needed for the introduction of construction safety supervision. This means that there is a difference between owner and contractor in the perception of process according to system operation. All companies agree to system improvement by the settlement of safety supervision system for the prevention of safety accidents and safe construction, but the systematic complement of safety supervision is the burden of contractor. And there is a big difference between owner and contractor in the perception of responsibility and concern for cost burden.

The purpose of this study was to explore the general tendencies of major variables and sex differences and to analyze the variables that affect delinquency and aggression. The protective factors considered in this study included parental education participation, parental supervision, and peer attachment, and the risk factors were academic stress and delinquency experiences of peers. The main results of this study are as follows: firstly, academic stress and parental education participation was slightly low, but parental supervision was high. Further, peer attachment showed a very high score. Delinquency experiences of peers, delinquency, and aggression of adolescents were extremely low. Secondly, the correlation of parental education participation, parental supervision, and peer attachment was negatively related to adolescent delinquency, but the delinquency experiences of peers were positively related to adolescent delinquency. The same results were obtained in the case of adolescent aggression. Further, academic stress was negatively related to adolescent aggression. Finally, hierarchical regression revealed that the variables explaining the juvenile delinquency were parental education participation, peer attachment, and delinquency experiences of peers. Adolescent aggression was explained by sex, academic stress, parental education participation, and the delinquency experiences of peers. In particular, more attention is needed for girls. Various interventions should be provided to prevent problem behaviors.

Since the Global Financial Crisis of 2008-2009, the importance of nonbank financial institutions in macroprudential management has increased significantly. Consequently, major countries and international financial institutions have been actively discussing and implementing macroprudential supervision and regulation for non-bank financial institutions (NBFI). In this context, this paper analyzes the systemic risk of both banks and non-bank sectors (securities firms and insurance companies) in South Korea over different time periods. Using the widely recognized ΔCoVaR methodology for measuring systemic risk, the analysis reveals that systemic risk increased substantially across all three sectors (banks, securities firms, and insurance companies) during the Global Financial Crisis, the European Sovereign Debt Crisis, and the COVID-19 pandemic. Although the banking sector exhibited relatively high systemic risk compared to the securities and insurance sectors, the relative differences in systemic risk varied across the different crisis periods. Notably, during the margin call crisis in March of 2020, the gap in systemic risk between the banking and securities sectors decreased significantly compared to that during both the Global Financial Crisis and the European Sovereign Debt Crisis, indicating that securities firms had a more substantial impact on risk in the overall financial system during this period. Furthermore, I analyze the impact of the issuance of equity-linked securities (ELS) by financial institutions on systemic risk, as measured by ΔCoVaR, finding that an increase in the outstanding balance of ELS issuance by financial institutions had an impact on increasing ΔCoVaR during the three crisis periods. These findings underscore the growing importance of non-bank financial institutions in relation to South Korea's macroprudential management and supervision. To address this evolving landscape, enhanced monitoring and regulatory measures focusing on non-bank systemic risk are essential components of maintaining financial stability in the country.

As asbestos-containing buildings are getting older, asbestos deconstruction works are increasing. As a result, accident risks such as falls, cuts, electric shocks, and suffocation are increasing. Existing studies are mostly about health management and institutional policy research and there is little research on work risk. So workplace risk assessments that are easily applicable in the field are required to be applied. Sealing is the first process of asbestos deconstruction and is the first step to ensure worker's safety. Job Safety Analysis(JSA) and Checklist were used to identify the risk factors and to calculate the level of the risk. By comparing the two risk assessment tools, it was figured out that the JSA is appropriate for the initial process and change of work procedure while Checklist is appropriate for repetitive work. Because the sealing process is sort and simple, it is unlikely to cause serious injury. But since the risk of falling and cuts are exist, safety education and supervision are necessary to maintain a safe working environment.

최근 인터넷 금융이 중국 내에서 다양하게 통합되면서 새로운 형태의 금융이 형성되고, 중국의 실물경제 구축과 포용적 금융으로 빠르게 새로운 금융의 통로가 되고 있다. 본 논문은 중국 인터넷 금융플랫폼의 패널자료를 토대로 인터넷금융위험의 영향요인을 랜덤효과모형을 이용하여 분석한 결과 다음과 같은 결과를 얻었다: (1) 금융플랫폼의 사용자펀드와 플랫폼펀드관리를 통하여, 인터넷상의 거래에서 금융리스크를 효과적으로 줄일 수 있다. (2) 규제정책을 통해 플랫폼 자금이 소수의 대출자에게 집중되는 것을 피함으로써 인터넷 금융거래의 위험을 효과적으로 줄일 수 있다. (3) 자금의 유동성 통제는 인터넷 금융 거래의 위험을 효과적으로 감소시킬 수 있다. 연구결과로, 인터넷 금융의 건전하고 지속가능한 발전을 위한 규제정책에 대한 최적화 전략을 제안하였다.

In this study we suggested two optimization models to determine conversion weight of convertible bonds. The problem of this study is same as that of Park and Shim [1]. But this study used Value-at-Risk (VaR) for risk measurement instead of CVaR, Conditional-Value-at-Risk. In comparison with conventional Markowitz portfolio models, which use the variance of return, our models used VaR. In 1996, Basel Committee on Banking Supervision recommended VaR for portfolio risk measurement. But there are difficulties in solving optimization models including VaR. Benati and Rizzi [5] proved NP-hardness of general portfolio optimization problems including VaR. We adopted their approach. But we developed efficient algorithms with time complexity O(nlogn) or less for our models. We applied examples of our models to the convertible bond issued by a semiconductor company Hynix.

Purpose: The purpose of this study was to explore the parent related factors that influence internet game addiction among elementary school students. Method: Data was collected through self-administered questionnaires and descriptive statistics, t-test, ANOVA, correlation and stepwise multiple regression were used to analyze the data. Data survey was conducted with 739 conveniently selected students who were in grades 4, 5, and 6 of elementary schools in Seoul or Gyung-gi province. Results: The addiction groups were classified as general user group (84.3%), potential risk group (10.0%) and high risk group (5.7%). There were significant internet game addiction differences by gender, grade, expense of internet cafe, religion, school record, place where child played, economic status, and duration and frequency of game play. The addiction was negatively correlated to parents' attachment, supervision, attitude to child nurturing, and expectations regarding school study. The most significant variables were both parents' attitude to child nurturing, and mother's supervision. These three variables explained 20.7% of internet game addiction in elementary school students. Conclusion: These findings are expected to make a contribution to the creation of ideal interventions at school, home, and counselling centers to prevent internet game addiction.
