In order to ensure the right of self-determination of women, most of countries allow women to buy post-coital contraceptive pills or general medical supplies with ease. This study aims to analyze how ordinary people recognize and respond to post-coital contraceptive pills through collecting atypical data by using the keyword 'Contraception', rather than using the existing actual condition survey, such as questionnaire and interview, so that the results have been presented, which may be referred to for establishment of policies.

최근 기술의 급격한 발달과 기업환경의 변화 및 자연환경의 변화로 인해 다양한 리스크 문제들이 대두되고 있고 리스크의 범주도 확대되고 있다. 리스크 관리 실패는 기업 및 국가경쟁력에 상당히 많은 영향을 미친다. 기업 및 국가에서는 리스크를 관리하기 위해 리스크경영시스템을 구축하고, 리스크를 최소화하여 리스크로 인한 손실비용을 줄이기 위해 노력하고 있다. 이에 본 논문에서는 국내외 리스크경영시스템 및 리스크 관리, 리스크 분석기법들을 조사 연구하여 리스크경영시스템 구축에 있어 필요한 기초자료들을 제시하고자 한다.

홍수피해를 발생시키는 외부적인 요소 측면에서 과거와는 다른 강우특성이 뚜렷이 나타나고 있고, 홍수 피해의 측면에서 홍수에 의한 피해 잠재성이 매우 커지고 있는 시점에서 치수대책은 내 외부적인 여건변화에 민감하게 대처해야 한다. 수자원장기종합계획보고서(국토해양부, 2006)에서는 과거와 같은 제방위주의 치수대책으로는 변화하고 있는 강우상황에 대처할 수 없을 뿐만 아니라 급증하는 홍수피해를 줄이기에는 한계가 있다고 강조하고 있다. 따라서 이와 같은 내 외부적인 환경변화에 대응하기 위해 새로운 패러다임의 홍수대책의 수립이 필요하고, 급변하는 기후변동에 의한 유역의 홍수취약성을 파악하기 위한 지표를 개발하여 치수 정책과 관련 사업의 의사결정을 지원할 수 있는 체계가 뒷받침 되어야 한다. 본 연구에서는 P(Pressure, 압력)-S(State, 현상)-R(Response, 대책) 구성체계를 기반으로 홍수위험지수(Flood Risk Index, FRI)를 개발하여 유역 간 홍수의 취약성 비교 분석을 하고 해당 지역의 주된 취약요인을 파악하여 정부 및 지자체의 치수관련 정책 결정을 효과적으로 지원할 수 있도록 하는데 목적이 있다.

Recently, the earth's highest temperature is rising due to severe climate change and heat wave. In addition, due to the increase of elderly population over 65, the number of heat patients is also increasing. In particular, the elderly who live alone in poor living environments, the lower income group, and the socially disadvantaged, such as children and pregnant women, are exposed to the dangers of heat waves, so the government's practical measures are urgently needed. In this study, we will build a visualization platform for each level of heat wave and provide the necessary countermeasure solution according to the heat wave risk. "The Hazard Visualization Platform for Heatwave" provide not only simple information, but also a customized safety service for citizens to prevent heatwaves, respond to heatwaves, and utilize heat wave information.

Since the Fukushima accident in 2011, the importance of the electrical systems in nuclear power plants (NPPs) has been emphasized. The result has been that NPP regulators are enhancing their monitoring of loss of offsite power (LOOP) events. Korea Hydro & Nuclear Power Co. (KHNP) is reviewing the status and issues related to LOOPs, and is attempting to establish specific countermeasures to prevent LOOPs, because they can have severe consequences in the complicated maintenance schedule during an outage. A starting point for preventing LOOPs is the control of the loss of voltage (LOV)-initiating components. In order to reflect this in the risk assessment program, an LOV monitor is being developed for use during plant outages.

This paper defines the Safety Management System(SMS) based on the rail safety act and surveys the status of the English rail SMS and International Civil Aviation Organization (ICAO) SMS and OHSAS18001 SMS. Through the investigation of establishment and implementation status of domestic rail operators' SMS, the improvement directions of the current rail SMS are developed. First, to establish the continual improvement system for SMS, the guide which describe detailed continual improvement method for each steps of SMS including management review by CEO shall be established and implemented. Second, to settle the SMS based on the risk management, it is necessary to endeavor for converting the rail operators mind and to establish the supply system of operating model and basic data and to define the requirement precisely and to include in the related guide for the risk management.

In the most current Turn-key bidding and Alternative design, is going to establish maintenance plan along with a economical assessment (VE/LCC assessment etc). Generally, establishment of maintenance plan is based on past experiences that are decided upon sensor position and amount with analytic or mechanical control section. But, it is more reasonable that maintenance plan based on level of significance for Probabilistic Risk, with presuming damage probability assessment of structural fracture scenarios. Therefore, in this study it is considered about the technique that an improved maintenance plan of railroad structures using PRA (Probabilistic Risk Assessment) on the basis of structural reliability theory. For this, in the paper, Preventive maintenance plan based on PRA is suggested with an application example of Pansong-Line (Line number 3) railway in Pusan works that actually executed Turn-key design.

Objectives: The purpose of this study was to determine the factors influencing oral health education of adolescents from multi-cultural families. Methods: The subjects were 711 multi-cultural adolescents from the 15th(2019) Korean youth risk behavior web-based survey. Multi-cultural adolescents were defind as the children of marriage migrant women. The collected data was analyzed using the chi-squared test and logistic regression; SPSS versin 18.0 was used. Results: Middle-school adolescents received more oral health education than their high-school counterparts. The adolescents with once-daily and twice-daily teeth brushing behaviors were 0.475 (p<0.05) and 0.784 times less those with thrice-daily behavior, respectively. Adolescents who received oral health education also experienced dental care 1.644 times more than their counterparts(p<0.05). Conclusions: The promotion of oral health among multicultural families and further education through the establishment of school oral health education programs are required.

Background: A diabetic foot is the most common cause of non-traumatic lower extremity amputations (LEA). The study seeks to assess the risk factors of amputation in patients with diabetic foot ulcers (DFU). Methods: The study was conducted on 351 patients with DFUs from January 2010 to December 2018. Their demographic characteristics, disease history, laboratory data, ankle-brachial index, Wagner classification, osteomyelitis, sarcopenia index, and ulcer sizes were considered as variables to predict outcome. A chi-square test and multivariate logistic regression analysis were performed to test the relationship of the data gathered. Additionally, the subjects were divided into two groups based on their amputation surgery. Results: Out of the 351 subjects, 170 required LEA. The mean age of the subjects was 61 years and the mean duration of diabetes was 15 years; there was no significant difference between the two groups in terms of these averages. Osteomyelitis (hazard ratio [HR], 6.164; 95% confidence interval [CI], 3.561-10.671), lesion on percutaneous transluminal angioplasty (HR, 2.494; 95% CI, 1.087-5.721), estimated glomerular filtration rate (eGFR; HR, 0.99; 95% CI, 0.981-0.999), ulcer size (HR, 1.247; 95% CI, 1.107-1.405), and forefoot ulcer location (HR, 2.475; 95% CI, 0.224-0.73) were associated with risk of amputation. Conclusion: Osteomyelitis, peripheral artery disease, chronic kidney disease, ulcer size, and forefoot ulcer location were risk factors for amputation in diabetic foot patients. Further investigation would contribute to the establishment of a diabetic foot risk stratification system for Koreans, allowing for optimal individualized treatment.

The methods of electronic financial fraud continue to evolve. Various research and countermeasures have been proposed to counter this problem, but it is difficult to eradicate it. The purpose of this study is to analyze the risk of electronic financial fraud through MS Threat Risk Modeling and to propose the countermeasures against the electronic financial fraud. As a result of the analysis, it is confirmed that despite the difference of authentication methods, there is a high risk of pharming, and it is difficult to prevent attack by using only additional authentication means, device security or user authentication based security system. Therefore, this study suggests the introduction of preventive measures such as readjustment of transaction limit by security means, account authentication, and additional physical security measures. It also suggests the establishment and implementation of a comprehensive electronic financial fraud prevention policy through linkage of electronic fraud prevention system and improvement of public relations and user awareness.
