  • This study applied risk indexes to the disaster flow event occurred at Mt. Umyeon region in 2011. A 2D hydrodynamic model was employed to calculate flow characteristics, and the model was validated against two dam break flow problems conducted by Bellos and EU CADAM project. The model performance was shown to be satisfactory. In order to determine which index is more appropriate to assess the vulnerability of debris flow, 3 risk indexes (FII, FHR and VDI) were considered. It was found that VDI, which determines the risk level only by the velocity factor, consistently predicted the risk level corresponding to 6 because the velocity range was widely organized. However, in the case of FII and FHR, the risk was reasonably quantified due to combined consideration of significant factors of flow velocity and debris thickness. Therefore, FII and FHR are expected to be more accurate than VDI. However, two indexes still need to be improved to include major factors such as debris density or material properties.

  • The purpose of this study is to establish a method for assessing a building's risk against disaster, tentatively named the Korean integrated disaster evaluation simulator (K-IDES). Based on previous studies, FEMA's risk management series and FEMA IRVS are selected as case studies for developing a frame work of K-IDES, through the comparative analysis of domestic building design guides, codes, and special acts related to disasters, in order to develop a risk assessment methodology for quantitative results. The assessment method consists of a classification system and calculating risk, and a simulation applying the developed checklist in K-IDES to similar types of high-rise buildings will be conducted to validate its accuracy. The final goal is to systemize an integrated risk management in a high-rise building against disasters for the purpose of recognizing vulnerable areas from the beginning of the design process and reinforcing it from potential threats after construction.

  • This paper introduces the applications of Taiwan Earthquake Loss Estimation System (TELES), which is developed by the National Center for Research on Earthquake Engineering (NCREE). Seismic disaster simulation technology (SDST) integrates geographical information system to assess the distribution of ground shaking intensity, ground failure probability, building damages, casualties, post-quake fires, debris, lifeline interruptions, economic losses, etc. given any set of seismic source parameters. The SDST may integrate with Taiwan Rapid Earthquake Information Release System (TREIRS) developed by Central Weather Bureau (CWB) to obtain valuable information soon after large earthquakes and to assist in decision-making processes to dispatch rescue and medical resources more efficiently. The SDST may also integrate with probabilistic seismic source model to evaluate various kinds of risk estimates, such as average annual loss, probable maximum loss in one event, and exceeding probability curves of various kinds of losses, to help proposing feasible countermeasures and risk management strategies.

  • This study aims to contribute to urban policy for more effective disaster prevention, as abnormal natural disasters are becoming more frequent. Up to now, the urban plan for disaster prevention in Korea merely includes basic principles and necessities of measures as an early stage. Furthermore, there are difficulties to make specific programs because the legal system, technical instruments, and financial supports are not sufficient. Therefore, this study figures out problems in the current plan related to urban prevention after analyzing the legal system and practices. Resulting from case studies in developed countries, the study draws significant implications, as follows: enhancing legally binding force; improving the procedures for the programs; establising technical infrastructure. It first suggests a way for the urban policy for disaster prevention by considering our local features comprehensively. It then defines the roles of central, local governemnts and research institutions, and the procedure for urban disaster prevention planning building on the individual roles. This study concludes that an emphasis should be placed on institutional tools necessary to publish technical guideline and establish the system so that urban planners more easily access to disaster risk information.

  • Risk that breed large size disaster is happening variously for cause at social. natural a management. Incidence and damage scale are trend that increase rapidly than past. In these circumstance, to keep operational continuity of organization, area, society, risk management action that establish systematic counter measure estimating and analyze occurrence possibility and expectation damage of risk is essential indispensable issue and the best countermeasure. Risk management action does by main purpose establish optimum disaster reduction countermeasure. To deduce various countermeasure, process that estimate and analyze occurrence possibility and expectation damage of risk is essential indispensable issue. Therefore, this paper studies process design that can presume risk occurrence frequency and damage scale through distribution of probability.

  • 연구목적: 수소충전소의 위험성 평가의 한계를 보완하고자 운영중 발생 가능한 사고에 대한 안전성 및 사업연속성을 강화하기 위한 방안으로 기업재해경감활동을 적용을 제안한다. 연구방법: 수소충전소 설치 및 운영의 시간 흐름에 따라 위험을 구분하고, 핵심업무를 식별, 위험시나리오를 도출하여 이를 분석, 평가, 처리하는 과정을 통해 위험을 경감, 제거,전가, 수용할 수 있는 기업재해경감활동의 일부적용을 탐구해 보았다. 연구결과:수소충전소 설치전 단계에 시행하고 있는 위험평가는 기존의 연구 결과가 적절히 적용되고 있다. 그러나 운영단계에서 발생 가능한 위험에 대해서는 한계가 있어 몇 가지 예시 시나리오를 가지고 기업재해경감활동을 적용해 보니 안전성과 사업연속성 강화 방안으로 적용이 가능하다는 결과를 도출하였다. 결론:현재 시행중인 수소충전소 위험성평가는 모두 적절하게 활용되고 있다. 그러나 운영단계에서 발생 가능한 위험에 대한 평가와 대응방안으로 다양한 위험시나리오를 적용하는 기업재해 경감활동을 제안한다.

  • 최근 기후변화로 인한 태풍, 국지성 집중호우 등 자연재해에 의한 피해가 급증하면서 행정안전부에서는 「소규모 공공시설 안전관리 등에 관한 법률(2016 개정)」을 제정하고 각 지자체별로 소규모 공공시설을 조사하여 국가재난안전관리시스템(NDMS)에 등록하고 매년 3월 31일까지 안전점검을 실시하고 있다. 이를 위해 최근 각 지자체별로 소규모 공공시설 안전점검 및 정비계획 수립 용역이 발주되어 세천, 소교량, 농로, 마을진입로, 취입보, 낙차공의 6가지 유형의 시설물을 조사하여 DB화 하고, 각 시설물별 위험도 평가를 수행하여 위험시설의 경우 정비계획을 수립하고 있다. 그러나 현재까지 배포된 소규모 공공시설의 위험도 평가 방법은 현장조사자의 육안조사를 통해 이루어지고 있으므로, 위험도 평가가 주관적이고 모호한 형태로 이루어지고 있는 실정이다. 이에 본 연구에서는 소규모 공공시설 중 재해위험도가 가장 높은 세천에 대하여 위험도 정량평가지표를 제시함으로써 합리적이고 정량적인 위험도 평가가 이루어질 수 있도록 하였으며, 이를 통해 소규모 위험시설을 선정하여 정비계획 및 시행계획 수립에 있어 투명한 근거자료를 확보할 수 있도록 하였다.

  • Purpose: This research aimed to provide baseline data for undergraduate safety education by evaluating paramedic student risk perception and safety practice behavior regarding transport and disaster-related accidents. Methods: A total of 367 paramedic students at three different universities were surveyed using questionnaires. Risk perception questions about hazard, feeling of dread, and uncontrollable factors regarding seven items in transport and disasters were asked on a 7-point scale. Safety practice behavior consisted of 14 transport-related questions and 12 disaster-related questions in 4-point scale. All data were analyzed using SPSS Window 21.0. Results: Of 367 surveyed, 54.8% (201) were females, and 28.9% (106) were freshmen. In risk perception, 'drunk driving' in transport was the highest on average obtaining 6.49 points for hazard and 5.12 points for the feeling of dread. In disasters, 'war' recorded the highest average with 6.61 points for hazard and 5.71 points for the feeling of dread. In safety practice behavior regarding transport and disasters, a higher awareness of the need for safety education correlated with a significantly higher the rate of safety practice behavior (p <.001 respectively). Conclusion: The results indicate that undergraduates have inadequate perception of risk in emergencies. Safety education programs are needed to raise awareness of risks and to increase the safety practice rate.
