최근 우리나라 주변에 잦은 지진으로 인한 재해위험도 증가 우려가 커지고 있다. 국내 외에서 지진해일 위험도 평가는 시나리오를 기준으로 수치해석을 수행하고 이들 결과를 활용하는 절차로 수행된다. 그러나 위험도 평가는 하중조건 즉, 지진해일을 발생시키는 지진의 발생빈도 및 크기를 종합적으로 고려한 확률 계산이 우선적으로 요구되나, 기존 분석 절차에서는 고려가 되지 않거나 상대적으로 간략화 되어 진행되고 있다. 이러한 점에서 본 연구에서는 과거 우리나라 주변에 지진 및 지진해일 자료, 수치해석 모형 결과를 활용하여, 지진의 규모와 발생빈도를 종합적으로 고려할 수 있는 지진해일 위험도 평가 방법을 수립하고자 한다. 본 연구에서는 첫째, 지진 위험도 평가를 위해서 Poisson-Pareto 분포를 이용하였다. 둘째, 지진발생 위치 및 크기를 고려한 지진해일 위험도 평가 모형을 개발하였다. 셋째, 지진발생 위험도 및 지진해일 위험도를 통합한 해석 모형을 개발하고자 하며, 본 연구애서 제시하는 모든 해석 절차는 매개변수의 불확실성을 고려할 수 있도록 Bayesian 해석기법을 도입하여 진행하였다.

정보통신 인프라를 운영하고 있는 조직은 주요 점보자산의 위형, 취약성 및 위험 분석.평가에 많은 관심이 고조되고 있다. 위험 분석.평가는 다수의 평가자(전문지식을 가진 평가자)의 주관적인 관점이 많이 작용하며 평가결과들 간에 평가 결과에 대한 문제를 야기 시킬 수 있다. 따라서 다수의 평가자들의 평가의견을 보다 효과적으로 결합(적용)할 수 있는 절차 및 방법이 요구된다. 본 논문에서는 분산 환경에서 다수의 평가자들의 평가의견을 집합개념 중 서로 다른 집합끼리의 합을 구하는 절차에서 착안하여 이를 적용한 실용적인 위험분석 방법론을 제시한다.

Purpose: This study intends to review the risk assessment procedures specified in the corporate disaster management standard. Method: The requirements for each stage of risk assessment stipulated in the corporate disaster management standard were identified, the case of application of the organization'A' and the partner companies were reviewed, and the risk assessment procedure in line with the requirements was reviewed. Result: It was reviewed that it was necessary to clearly define the method and procedure for deriving risk scenarios, which are the requirements of the corporate disaster management standard, and to introduce a standardized procedure for deriving risk scenarios. Conclusion: A method of deriving risk scenarios was implemented by applying the STPA technique based on the system theory for power generation fuel supply and demand, and it was suggested that the STPA technique be reflected in corporate disaster management standards as a risk scenario derivation technique for the establishment of a disaster reduction activity plan.

본 논문에서는 파일 포맷에 대한 위험요소 평가를 기반으로 해당 포맷에 대한 장기보존 방안을 제시하는 절차 및 시스템 구축에 필요한 아키텍처를 정의하였다. 파일포맷이 사양화된 경우 이를 재현할 수 있는 장기보존전략으로 마이그레이션과 에뮬레이션 방안이 제시되고 있는데 개별 포맷에 대한 위험도 평가를 통해 가장 적합한 보존전략을 선정하여 전자기록의 재현성을 부여하는 연구를 진행하였다.

This paper presents a risk assessment methodology for standard flight procedures using recorded automatic dependent surveillance-broadcast (ADS-B) data. Utilizing the proposed methodology, the results of risk analyses in RKSI (incheon international airport) and RKSS (gimpo international airport) using trajectories that are regenerated based on 100 days of ADS-B data are presented. For the risk metric, detect and avoid well clear (DWC) is used. With this index, each procedure was evaluated for the sections with highest level of risk. Among the standard instrument departure (SID) of RKSI, the section between SI712 and RANOS of RNAV BOPTA 1L showed the highest level of risk. For the standard terminal arrival route (STAR) of RKSI, section between SI947 and DANAN of RNAV GUKDO 1N wasthe one with the highest level of risk. For RKSS, the segment between SS726 and SS727 of RNAV BULTI 1X and the segment between KAKSO and KALMA of RNAV OLMEN 1D showed the highest level of risk among the SIDs and STARs, respectivly.

In the paper, we can select the best safeguard as proposed the definite and systematical method and procedure on risk mitigation of risk management for information system. The practical risk mitigation methodology has a good fulfillment procedure and a definition to fulfill procedure on each phase. So, it is easy to fulfill and can apply to any risk management methodology. The practical risk mitigation is composed of 6 phases, which are the existing safeguard assessment, safeguard means selection, safeguard technique selection, risk admission assessment, cost-effective analysis and safeguard embodiment. The practical risk mitigation's advantages are as follow. Efficient selection of safeguards to apply to risk's features with safeguard's means and techniques before embodying safeguards. Prevention of redundant works and security budgets waste as re-using the existing excellent safeguards through the existing safeguard assessment. Reflection of organization's CEO opinions to require special safeguards for the most important information system.

산업화가 진행됨에 따라 점점 복잡해지고 위험해 가고있는 산업설비에는 사고의 리스크가 잠재하고 있다. 이러한 위험설비와 위험시설물에서 발생될 수 있는 중대한 사고의 경우 그 사고의 예방과 피해최소화를 위해서 사고관리방안이 강구되어야 하고 그 방안을 수행할 절차서의 개발이 이루어 져야하고 개발된 절차사에 대한 사용교육과 훈련이 병행되어야한다. 이를 위해 선행되어야 할 것은 어떠한 사고관리방안이 최선인지를 평가하는 사고관리 방안의 평가가 필요하다. 사고관리 방안평가에 수반되는 불확실성의 모델링에는 의사결정수목 (Decision Trees) 영향도 (Influence Diagrams)의 이용할 수 있다. 본 연구는 이러한 사고관리방안 평가를 위한 도구 (Tools)을 개발하여 사고관리방안 평가체계를 세우고 아울러 개발 된 평가체계의 실현성과 적용가능성을 보이고자한다.

Recently risk management based on a quantitative assessment is considered to improve the level of safety in Korea. This paper focuses on the procedure of the quantitative risk assessment for natural gas pipelines. For that purpose, the methods to estimate failure frequency based on failure causes from European Gas Pipeline Incident Data Group and BG Transco, to analyze consequence caused by fire, and to calculate individual risk and societal risk have been proposed systematically in this paper. Risk criteria of individual risk and societal risk have been proposed by considering the environment of pipeline route in Korea. The proposed procedure of quantitative risk assessment may be useful for risk management during the planning and building stages of a new pipeline, and modification of buried pipeline.

This paper proposed risk management approach as a self-audit framework to achieve the goals which might be common among the records management organizations in Korea governmental and public area. After introducing the history and the concept and process of risk management approach and examining DRAMBORA's framework, the processes and the methods of risk management for the electronic records which are customized from DRAMBORA are explained in details: How to define the business context of organizations, how to determine the business functions and activities and related risks, how to assess the level or severity of each risks and some considerations related to risk assessment. As a result, this paper shows that application of DRAMBORA's framework to the electronic records management organizatioins is not only possible but also useful and effective. The critical point for the success of application for DRAMBORA's framwork or the risk management approach itself each organizations which wants to accept that framework should define its own business functions and activities and the goals in respect areas.

'Navigable airspace' means an airspace at and above the minimum safe flight level, including airspace or flight procedures needed for safe takeoff and landing. Airspace may be established as needed and may be abolished, and in some cases may be limited to airspace management. These are absolutely based on risk assessment. Safety is the state in which the risk of harm to persons or of property damage is reduced to, and maintained at or below, an acceptable level through a continuing process of hazard identification and risk management. 'Risk' is the assessed potential for adverse consequences resulting from a hazard and 'Risk assessment' involves consideration of both the frequency and the severity of any adverse consequence. This paper proposed 'risk assessment procedure' for the structural changes of Navigable Airspaces through literature reviews relevant to manuals on airspace management and risk management.
