  • A variety of risks caused by natural, technological and biological hazards threaten a business continuity of an organization. Business continuity is very important issue for all organizations and its proper management may control success and failure of an organization. Business continuity plan (BCP) may be defined as a management process which provides a business continuity. BCP includes risk management, operational continuity plan, response/ recovery, exercise/study and crisis communication, etc. Risk management is a systematic method to identify, analyze, evaluate and treat emergency risks and risk assessment is composed of identifying, analyzing and evaluating emergency risks. Risk assesment is the first step for making BCP. In this study, risk assessment has been conducted for sewer laying project. Through assessing risks, 18 risks that may threaten the construction operation are identified and it is founded to be that high levels of risks which require treatment are 'collapse of excavation surface', 'breakage of ground infra-facilities', 'noise & dust dispersion' and 'rise of material costs'.

  • Project risk assessment is the most important activity performed at the beginning of a project because it can judge the performance of the project in advance. In this study, We were evaluated risk with traditional risk factors such as technology and schedule, etc, and Indirect risks factors such as financial, strategic, and special risks. and then, we analyzed what kind of relationship these risk evaluation factors have on business performance and customer satisfaction. As a result of the research, it was found that the risk evaluation items had a relationship with performance and customer satisfaction. However, It is possible that the performance may differ depending on how risks are managed after risk assessment. Therefore, follow-up studies should be conducted, including information on risk management practices. This study is meaningful that presenting practical risk evaluation items and at the same time identifying the relationship with performance. We plan to further the study in future studies including the evaluation of risk management process.

  • Recently, climate change risk assessment has been discussed as a medium process for making climate change adaptation policies in the research field of climate change adaptation. Climate change risk assessment has been understood to have an intermediary role among impact assessment, vulnerable assessment and policy, and is used in the process of devising adaptation policies in the United Kingdom (UK). This paper quantitatively assessed the risks of climate change in Korea, applied the methods used in the UK, underwent the classification process and suggested implications of Korean adaptation policies. A survey of experts, based on Delphi's method and the classification criterion developed by Klinke and Renn(2002), was also carried out. A list of climate risks was created from the climate change impact and vulnerability assessment report of Korea, first national adaptation policy of Korea, and general climate risks of the UK. From the results, 42 risks out of total 125 risks were selected based on their importance. The assessed risks with factors, such as high impact and urgency, are related to repeated and large scale damage from storms and floods caused by abnormal or extreme weather events. Ecological changes and social infrastructure risks were engaged as required as a policy response for medium to longer term. As for making the classification, types of climate risks were suggested to manage the basic capacity in relation to social trust, triggering mechanism and responsibility. Following suggestions are put forward as the base of autonomous adaptation: increasing the capacity of civil society, mutual trust and civil participation in adaptation policy process.

  • Project risk factors are major triggers in cost performance in construction projects. Both owners and contractors are highly concerned in managing their risks in earlier times. As such, it is needed to provide a robust risk evaluation methodology in identifying and assessing the potential risks before project execution. In previous research, risk identification was conducted only in specific phases, i. e., design, procurement, construction. Therefore, the comprehensive approach in risk management was limited and their quantifying method was not well-defined. Since the benefit of planning in earlier times are maximized compared to later times, the risk management should be implemented in earlier planning stage. This study provide a new risk evaluation method by incorporating previous research and extensive literature review. By quantifying each risk factor from an extensive industry survey, the proposed tool can enhance the reliability of each factor weight and also the weights are categorized from a various perspectives, i.e., owners, contractors, lager-scale company, smaller-scale company, building projects. The proposed tool can be also useful in deciding on whether to proceed a particular project and How much the project contingency would be set aside in project execution. The study findings can also expedite the risk management procedure in a more systematic approach.

  • Recently, safety accidents of daily necessities such as humidifier disinfectant, mobile phones, and infant diapers, have occurred frequently. To protect consumers from these accidents, product safety management is required, and a product risk assessment tool is needed to evaluate the degree of safety of the product. In this paper, we have constructed RAS, which is a system that can evaluate product risk based on injury information of product accident in Korea Consumer Agency. RAS consists of an injury information analysis system for analyzing accident-related information and a risk assessment system for assessing risk using information derived from the system. The Bayesian network - based probabilistic method is applied to reflect the causal relationships that affect product risk in the risk assessment process. We used RAS to evaluate 33 children's products and compared them with the results of EU RAPEX RAG. Subsequent tasks include reducing the subjectivity of the input of the accident impact scale, and linking the above two systems.

  • As an increasing demand for rapid railway transportation, the construction of sidetrack is inevitable to operate local and express trains simultaneously. However, the current technologies for the sidetrack construction method require a long construction period by interrupting the operation of the existing subway line, as well as cause a huge economic loss. Thus, it is necessary to study the sidetrack construction method under the special situation that the subway is in operation and to analyze the risk of the existing tunnel enlargement process for the sidetrack construction. Therefore, in this paper, the Government Complex Gwacheon station on Subway Line 4 was considered as a target station for the virtual sidetrack construction and the optimal sidetrack construction plan was derived. Subsequently, the application of risk management process was carried out in the order of identifying risk, risk response planning, performing a risk analysis, risk monitoring and control for potential risk events during the construction of sidetrack under the subway operation. A total of eight potential risk events and risk mitigation methods were selected, and a risk assessment matrix was established using the five-step risk probability and impact level criteria to perform the risk assessment including residual risks. Based on the results of the risk assessment, the risk grade and the reduction effect of each risk mitigation method were confirmed.
