연구목적: 공급체인관리에서 다룬 선행연구를 기반으로 요인을 분석하여 비즈니스 연속성 관리시스템(BCMS)의 위험평가와 위험관리 요인이 경영성과에 미치는 영향을 검증하였다. BCMS의 위험요인을 도출하고 예측 불가능한 위험을 평가함으로써 체계적인 위험관리 방안을 구축함과 동시에 기업이 업무중단 없이 경쟁우위를 선점하도록 기여하는데 연구의 목적이 있다. 연구방법: BCMS의 위험평가, 위험관리, 경영성과의 구조적 관계를 도출하였다. 이를 위해서 124명의 우리나라 기업에 종사하는 책임자, 관리자를 상대로 설문을 조사하였다. 빈도분석, 타당성분석, 신뢰성분석, 상관분석, 단순회귀분석을 하였다. 연구결과: 첫째, 위험평가는 위험관리에 정(+)의 영향을 미쳤다. 둘째, 위험관리는 경영성과에 정(+)의 영향을 미쳤다. 마지막으로 위험평가는 경영성과에 정(+)의 영향을 미쳤다. 결론: 기업의 경영성과는 BCMS의 위험평가와 위험관리 역량은 재무적 성과를 통해서 관리하고 위험관리 활동은 비재무적 성과를 통해서 관리해야할 것이다.

As the occurrence rate of terror and hazard is increasing throughout the world, GSA, DoD, and FEMA are proceeding a study about mitigating the damage of terror. Korea is no more a safe place from the terrorist's threat, so we need to make measures against them. In this study we developed modified RVS System by revising some items to adjust the system to the domestic condition and conducted a risk assessment on several tall buildings in Korea. By using IRVS system which is developed by DHS, we also carried out the risk assessment. Comparing the results between RVS with IRVS, we performed terror risk evaluation of tall buildings. Through risk assessment of several tall buildings, we analyzed key factors of each scenarios and suggested the mean value of each items, so we would like to help the counter-terrorism in the design phase.

Unmanned Aircraft Systems (UAS) are rapidly emerging not only as a key military power, such as surveillance and reconnaissance for military purposes but also as a new air transportation means in the form of Urban Air Mobility (UAM). Currently, airworthiness certification is carried out focused on the verification of technical standards for flight safety suitability of aircraft design in accordance with the Military Aircraft Flight Safety Certification Act and does not employ the model for operational risk assessment for mission areas and airspace. In this study, in order to evaluate the risk of the mission area from the perspective of the UAS operator, a risk assessment simulation has been conducted by applying the Specific Operations Risk Assessment (SORA) model to the operating environment of the Korean military UAS. Also, the validity of the SORA model has been verified through the analysis of simulation results, and a new application plan for airworthiness certification of the military unmanned aerial system has been presented.

Objective: This study aims to suggest different approaches in analyzing risks associated with musculoskeletal disorders (MSDS) for risk assessment. Background: Upon concluding that the changes in the industrial environments have made it hard to regulate diverse risk factors, the government has implemented a policy for risk assessment. Method: This study has proposed a method, creating programs using Excel that perform qualitative or quantitative analysis, for evaluating risk factors in risk assessments and has applied this in manufacture and service industries. Results: To verify the validity of the developed program, risk assessment has been performed on restaurant chefs as an example. For quantitative evaluation, the study has suggested approaches using the results for REBA evaluation and the analysis report on the work scenes of a fitting-shop in a shipbuilding industry. Application: Constructing and adapting a system using Excel in evaluating risk factors for risk assessments as this study suggests, is expected to contribute to revitalizing risk assessments.

2014년 철도운영자들과 철도시설관리자의 자발적인 안전관리를 정착시키기 위하여 철도안전법에서 '철도안전관리체계'를 강화하였다. 이에 따라 위험도를 평가하고 위험도를 관리하기 위한 안전대책을 수립하고 시행할 것으로 판단하였으나 현재 위험도 평가 체계는 개별 분야 내 단편적인 안전관리 수준으로 진행되고 있다. 또한 안전관리체계의 기술기준에서 철도 운영기관의 위험도 평가에 관한 내용이 의무사항으로 명시되어 있어 철도시설 및 철도차량유지보수의 위험도 평가를 위한 표준화된 기준이 필요하다. 따라서 본 논문에서는 최근 10년간 철도사고 데이터를 분석하여 먼저 철도 위험도 수준을 검증하였고, 철도차량유지보수 부분에서 데이터를 기반으로 개발된 상태기반 스마트 유지보수 시스템 사례를 통해 위험도를 효과적으로 평가하고 관리할 수 있는 표준화된 프레임워크를 제시하였다.

Power supply system of electric railway has a diversity of safety problems since it should supply high electric power to the trains moving high speed with a lot of passengers on board. This paper provides a risk assessment approach to safety management of the electric railway facilities. Construction of database from field accident information, risk assessment and management of the risk are carried out systematically to ensure the safety. The risk assessment includes hazard identification, cause analysis by FTA(Fault Tree Analysis), consequence analysis by EVA(Event Tree Analysis), and loss analysis. In terms of the severity and the probability of the accidents deduced by these analyses, the risk of the accidents is assessed by using a risk matrix designed for electric railway facilities. Based on the risk assessment, possible risk mitigation options are identified and evaluated by analyzing their impact on the risk reduction and their cost benefit ratio. The long-term safety of the electric railway facilities can be ensured by renewal of the risk assessment and the risk mitigation option analysis with continuous accident database update. The proposed approach is applied to the electric railway facilities of Korean railway based on the accident data from 2002 to 2008.

The railway system consists of rolling stocks, facilities, electrical system, signaling and operation and so on, organically bound. Recently due to lots of train failures and accidents, especially the derailment related to track irregularity this year, all the people using the train are worried about railway safety and we paved the way for letting them knowing that all components of railway system are so important. As a result, most of developed countries operating railway have used to risk assessment methods about safety management to prevent railroad accidents in advance. The purpose of this paper is to find out how to closely apply to track field for risk assessment methods. Because there is no case to apply to and we're not interested in yet, despite of importance of track, in situations of higher train speed. Therefore, in this study we're going to investigate risk assessment methods and compare enire railway system with track system, eventually we want us try to present to safety management conditions necessary and secure safety improvement in track field.

System risk is the totality of all safety risks to customers, employees, suppliers, and other third parties that arise due to system operations. To assess the risk of major hazards with the potential to cause fatality to the customers and other members of the public, quantitative risk assessment methodologies are used. This paper presents the general principles of risk based management approach to improve the safety of high risk systems such as aviation, railway, and nuclear power plants. For the suitable risk control arrangement, case studies of acceptable risk level, risk rating matrix, and safety management philosophy are presented.

Although Korea coastal area has the increasing potential marine accident due to frequent ship's encounter, increased vessel traffic and large vessel, there is no specific model to evaluate the navigating vessel's risk considering the domestic traffic situation. The maritime transport environmental assessment is necessary due to the amended maritime traffic law. However, marine safety diagnosis is now carried out by foreign model. In this paper, therefore, we suggest a domestic traffic model reflecting the characteristics of korea coastal area and navigator's risk as we named PARK(Potential Assessment of Risk) model. We can evaluate the subjective risk by establishing the model and model output into maritime risk exposure system. To evaluate this model's effectiveness, we used ship handling simulation and applied, analyzed collision accident which occurred in korea coastal area. And also, we applied integrated to an ECDIS program for monitoring traffic risk of vessels with real time based AIS data and apply to evaluate traffic risk in busan harbor waterway. As a result, we could evaluate busan harbor waterway risk effectively.

Recently, the Ministry of Labour, published clause 2 of Article 41 (Risk Assessment) of the Act "Industrial Safety and Health" dated 12 June 2013 in connection with continuous increase of accidents at construction sites in order to prevent accidents in industrial safety and health in new construction in accordance with the risk assessment on construction projects are realized after March 13, 2014. In this paper, positive method of calculating risk discussed by performing research the awareness of general contractors and sub-contractors with presenting risky situation is considered. The purpose will be a positive method of calculating risk and would be a sufficient base and give a positive direction in the development of new systems currently working in the construction and risk assessment which consider the characteristics of sufficient risk assessment system for future research.
