According to a recent study, most construction companies in Korea do not manage risk effectively, and it is judged that the risk management system needs to be improved. In addition, most risk-related studies deal with risks from a macroscopic perspective, and there are few studies dealing with process risks at the project construction stage. Therefore, this study tried to suggest a risk response plan through analysis and classification of risk factors that may occur in retaining work among process risks. To this end, a workshop was held for risk experts to identify and analyze risks that may occur during the construction of retaining work for apartments. As a result of the study, it was expected that savings of KRW 4.97 billion would be possible in the 95 % confidence interval, and the maximum possible cost was reduced from KRW 15 billion to about KRW 10 billion. Based on the risk reduction ratio, it was found that risks that can be reduced without any special input cost, risks with large effects in response to risks, and risks with insignificant effects were found. Therefore, using the types and risk factors presented in this study as guides, it is expected that it will be helpful in successfully operating the project if an appropriate response strategy is prepared and systematically responded to the site conditions.

The insufficient management o( the risk of preconstruction phase causes the risk of construction phase so it makes bad effects such as the extension of construction time and raising of cost. Therefore, the management of the risk of preconstruction phase is being considered as an important element of success of project and the competitive power of construction companies. This study Is to suggest solution methods for each progress after examining reasons of the risk for the management of the risk of preconstruction phase 1'he progress is limited as earth work, RC work, steel work and curtain wall work. Through the introduction of Knowledge Management system, work flow is made by specialist of each part. The reasons of the risk of progress are chosen through the analysis of work flow and I suggest detailed solutions such as person in charge, the starting point of progress and the information of requirements according to the grade of importance about elements of the risk

As construction projects have been extremely enormous, complex and special, risk factors have been increased consistently. Therefore, it is very important to identify and cope with the uncertain risk factors in such building constructions for successful project accomplishment. The purpose of this research is to approach practical affairs directly and show detail alternatives of risk factors by extracting the risk factors throughout construction process of curtain wall that is largely influenced on cost, quality, schedule ,safety and following activity. Also, extracting these risk factors make it possible to analyze quantitative risk and decide the priority raking of risk factors. Especially, this research is aimed to provide efficient management of scheduling risk that can make the risk minimize to practical workers who have different degree of knowledge and experience to the construction cite when the risk brings out suddenly.

복잡하고 숨가쁘게 변화하는 경영환경 속에서 리스크 관리 (Risk Management)는 기업경영상의 위험을 관리한다는 점에서 매우 중요한 과제로 대두되고 있다. 특히 PL법과 같은 새로운 법이 시행될 때마다, 기업은 새로운 재정적인 어려움에 직면하게 된다. 이 연구에서는 리스크 관리에 관한 국가규격들을 비교 검토하고, 특히 제조물 책임법의 시행에 따라 새롭게 등장하는 PL 리스크의 대응방안에 관하여 자금조달이라는 측면에서 고찰한다.(중략)

Recently construction environment is being professionalized. oversized and diversified. Due to fluctuation of construction environment, the demand for the project of steel structure is ieased gradually and steel construction is needed the efficient quality management. The construction of steel structure which required a variety of sub-contractors, the progress of works and technologies are comprehensive of various risks and uncertain factors. But currently the construction of steel structure is conducted the risk management by perception and experience of constructors. Therefore, the analyzing factors of the risk and establishing the device are able to manage the quality management efficiently. In this study, we have conducted the interview of experts, polls and through the Analysis Hierarchy Process (AHP) for the scientific and systematic risk management. This paper will propose a plan for systematization of the construction of the steel structure.

Most construction companies recognize the necessity of risk management. The practical application, however, is not easy because of the absence of systematic procedure for risk management and the difficulty in objectification of subjective risk factors. This study suggests a systematic procedure and a models. In the first place for those researches, this study analyzes the present condition of risk management in the construction industry. The developed model can be used as a risk management tool that enables evaluation of construction risk factors by quantified method, and it provides project managers with the methods to prevent risk and to deal with potential risk factors in the planning and construction phases. The results of this study could be used as references for related researches because this study attempts to develop a systematic tool for risk management including risk identification, risk analysis. risk action phases.

소프트웨어 테스팅에서 리스크 기반 테스팅은 리스크 식별, 리스크 분석, 리스크 계획, 리스크 추적의 4 단계로 전개되며, 특히 마지막 단계인 리스크 추적 단계에서는 식별된 리스크가 테스팅 진행과정을 거치면서 어느 정도 완화되었는지를 확인하고 현재의 리스크 완화 정도에 따라 적절하게 대응하는지를 모니터링 해야 하는 중요한 단계이다. 하지만 리스크 추적 단계에서 필요한 리스크 완화 수치가 정의되지 않아 사용자들은 테스트 실행율 또는 결함 해결율 등을 리스크 완화 수치의 대안으로 사용하고 있다. 본 논문에서는 리스크 추적 단계에서 사용할 수 있는, 리스크의 완화 정도를 수치화한 "리스크 해결 지수"의 산출 과정을 수식과 함께 제시하고 그 의미를 설명하였다. 그리고 예시를 통해 리스크 수치화에 대한 이해를 돕고, 리스크 수치화 관련 차트를 몇 가지 제시하여 실무에의 응용 통찰력을 제공한다. 리스크를 수치화한 "리스크 지수"는 테스팅 조직의 의사결정에 활용할 수 있는 객관적이고 설득력있는 정보로서 프로젝트 전반에 걸쳐 그 활용 가치가 높다.

In Korea, base metals such as lead, zinc, copper, tin, nickel, and aluminum have a polarized supply and demand structure. Despite the presence of world-class producers of lead, zinc, and copper, and their production is insufficient. And there are no domestic producers of tin, nickel, and aluminum, Thus, most of the domestic demand is dependent on imports. Therefore, it is necessary to prepare for the risk of supply interruption, such as the disruption of the import of base metals or interruption of domestic production. In this study, we estimated the quantity required to respond to the risk of import disruption, the quantity to which the market can respond, and the quantity to which the government needs to respond for six base metals (copper, lead, zinc, aluminum, nickel, and tin).
