Purpose: Based on the preceding studies in supply chain management, factors were analyzed to verify the effect of risk assessment and risk management factors of the business continuity management system (BCMS) on management performance. The purpose of this study is to establish a systematic risk management plan by deriving the risk factors of BCMS and evaluating unpredictable risks, and at the same time, contributing to a company's competitive advantage without interruption of work. Method: The structural relationship between risk assessment, risk management and management performance of BCMS was derived. To this end, a questionnaire survey was conducted of 124 managers and managers in Korean companies. Frequency analysis, validity analysis, reliability analysis, correlation analysis, and simple regression analysis were performed. Result: First, risk assessment had a positive (+) effect on risk management. Second, risk management had a positive (+) effect on management performance. Finally, risk assessment had a positive (+) effect on management performance. Conclusion: BCMS's risk assessment and risk management capabilities should be managed through financial performance, and risk management activities should be managed through non-financial performance.

Recently, because of the various factors by uncertainty of underground, the risks in tunnelling have been occurred increasingly. Therefore, it is very important to estimate and control the risks considering geotechnical conditions for tunnel stability and environmental problems by tunnel construction. In this study, the risk analysis for tunnel stability was carried out by classifying the risk factors such as ground support capacity, ground settlement, the inflow of groundwater into the tunnel and the damage by the earthquake. Also, the risk assessment for the environmental problems was performed by calculating the vibration and noise by blasting and the drawdown of the groundwater level caused by tunnel construction. Each risk factor was evaluated quantitatively based on the probabilistic and statistic technique, then it was analyzed the distribution characteristic along overall tunnel site. Finally, it was evaluated that how much each risk factor influences on the construction cost with a period for tunnel construction, so it is possible to perform reasonable tunnel design which was capable of minimizing the risks in the tunnel construction.

The purpose of the study is to identify risk factors and analyze risk impacts to increase R&D outcome by taking into consideration the activities undertaken in each phase of New Product Development(NPD) process. The paper builds on survey research that has been developed new IT products within the past 5 years at SAMSUNG and LG subsidiaries in the Republic of Korea. This study identified risk factors in accordance with NPD process and evaluated the identified risk factors with survey questionnaires. To analyze the risk impacts were used to perform a logistic regression analysis based on R&D output. The impact of risk factors were higher for the low-output group. High-output group took a risk into consideration unique undertakings in project management and managed risk factors effectively in order to increase R&D output. Consequently, with the aim of improving output of R&D, a risk management is necessary to identify the risk factors for each phase of NPD and focus on managing risk factors with great effect.

The importance of the Security Risk Analysis has emerged as security breaches and information leaks has occurred in the companies and organization: threats toward information system and its vulnerabilities has grown up as the dependence on the information-communication systems goes higher as a result of technological advances in IT industry, A Risk Analysis Tool helps to mitigate overall risk of an organization by analysing and evaluating critical information systems and providing security measures against threats to systems and its vulnerabilities as a means to identify the inherent dangers and prevent security intrusion incident, This paper defines risk analysis process by introducing Common Criteria Scheme and suggest a risk analysis tool that can be easily implemented by an information security manager.

최근 봄철을 맞아 산을 찾는 등산객의 수가 증가하고 있으며 그에 따른 안전사고 발생 위험도 높아지고 있다. 산지재해 중 가장 많이 발생하고 있는 산사태나 토석류는 산을 찾는 등산객에게도 많은 안전사고를 발생시키고 있으나 아직까지 탐방로의 위험성과 안전에 대한 연구는 미흡한 실정이다. 본 연구에서는 설악산 국립공원 탐방로를 중심으로 재해발생 이력조사 및 현장조사를 실시하고 분석에 필요한 공간 데이터를 구축하였으며 설악산 전체 탐방로를 유역단위로 분할하여 위험성 분석을 실시하였다. 전체 탐방로를 대상으로 GIS기반의 확률론적 분석과 SINMAP을 이용하여 위험성 평가를 수행하였으며 그 결과 일부 탐방로 구간에서 위험성이 높게 나타났다. 탐방로 위험구간을 유역별로 나누어 분석함으로써 탐방로 전체에서 유역단위로 위험요소를 판단하는 자료로 활용될 수 있을 것으로 판단된다.

위험도(risk)는 복잡성(complexity)과 불확실성(uncertainty)라는 2가지 주요 특징으로 인해 위험도를 정확하게 예측하는 것은 불가능하다. 대표적인 수공구조물인 댐이 각종 모니터링을 통해서 안전하다고 판단된다 하더라도 하류지역에 도시가 존재한다면 여전히 잔존위험도(residual risk)는 존재한다. 댐의 파괴가 일반적으로 발생하는 사상은 아니지만 대규모 인명피해, 재산 및 환경피해로 이어지기 때문에 작은 위험도라 할지라도 이에 대한 감시 및 관리가 필수적이다. 댐 위험도 분석을 위해서 Event Tree 또는 Fault Tree가 일반적인 해석 방법으로 이용되고 있으나 잠재적인 파괴모드에 대한 복잡성과 불확실성을 고려하는데 한계가 존재한다. 본 연구에서는 이러한 문제점을 개선하기 위해서 Bayesian Network 기반의 위험도 해석기법을 제안하고자 한다. 특히 수문학적 위험도와 관련된 분석을 위해서 Bayesian Network의 구성 방안, 매개변수 추정, 위험도 해석 등 기존 해석 방법을 개선한 댐 위험도 해석 기법을 개발하고자 하며 개발된 방법론을 국내 실제댐에 적용하여 적합성을 평가하였다.

본 연구는 일정 지역의 확률론적 지진위험도 (Probabilistic Seismic Hazard) 평가와 관련하여 전문가가 제시한 제1차 입력자료를 이용하여 제2차 입력자료를 도출할 때 입력자료의 다단계화를 통하여 각 단계별 구간의 입력자료가 확률론적 지진위험도 불확실성에 미치는 상대적 영향을 분석하였다. 확률론적 지진위험도 분석을 위하여 미국지질조사연구소 (USGS) 및 미국 로렌스리버모어 연구소(LLNL)가 개발한 전산코드를 각각 이용하였고 또한 전문가가 제시한 제 1차 입력자료는 기존 연구보고서에서 주어진 자료를 이용하였다. 분석결과 지진활동도 변수 특히 지진규모의 각 단계 및 감쇠특성함수의 진앙거리 단계에 따라서 확률론적 지진위험도의 절대값 및 불확실성에 미치는 영향의 차이가 상대적으로 크다는 것이 확인되었다. 또한 부지별로 이러한 분석을 함으로서 확률론적 지진 위험도 곡선에 영향을 미치는 임의 부지에 고유한 임계 지진규모 및 임계 진앙거리에 대한 분석을 통하여 전반적으로 불확실성을 감소시킬 수 있다.

Risk management should be controlled systematically by effectively evaluating and suggesting countermeasures against the various risks which are followed by the change of the society and environment. These days, enterprise risk management became a new trend in the field. The first step in risk analysis is to recognize the risk factors, that is to verify the vulnerabilities of loss in the security facilities. The second step is to consider the probability of loss in assessing the risk factors. And the third step is to evaluate the criticality of loss. The security manager will determine the assessment grades and then the risk levels of each risk factor, on the basis of the result of risk analysis which includes the assessment of vulnerability, the provability of loss and the criticality. It is of great importance to put the result of risk analysis in mathematical statement for a scientific approach to risk management. Using the risk levels gained from the risk analysis, the security manager can develop a comprehensive and supplementary security plan. In planning the risk management measures to prepare against and minimize the loss, insurance is one of the best loss-prevention programs. However, insurance in and of itself is no longer able to meet the security challenges faced by major corporations. The security manager have to consider the cost-effectiveness, to suggest the productive risk management alternatives by using the security files which contains every information about the security matters. Also he/she have to reinforce the company regulations on security and safety, and to execute education repeatedly on security and risk management. Risk management makes the most efficient before-the-loss arrangement for and after-the-loss continuation of a business. So it is very much important to suggest a best cost-effective and realistic alternatives for optimizing risk management above all, and this function should by maintained and developed continuously and repeatedly.
