The risk management industry has grown considerably in the past few years. Risk managers are entering the ranks of senior management, becoming a part of the decision making process and the oversight of its operations. Risks are inherent in any project. Furthermore, risk taking is essential to progress, and failure is often a key part of learning. Although some risks are inevitable, this does not mean that attempting to recognize and manage them will harm opportunities for creativity. Risk management is, and will remain, very much reliant on timely, clean and comprehensive data. Therefore, this paper was designed the current state of risk management practice, and planning the strategy of effectiveness risk management for company.

In this study, keyword network analysis was performed based on global and domestic journals, and network text analysis was conducted for news and articles to examine major issues and research trends on supply chain risks after COVID-19. As a result of analyzing the supply chain risk, after COVID-19 which was relatively insufficient in previous studies, research trends and topics such as supply chain risk recovery, response and public welfare, which are different from previous previous studies, were found in global and domestic journals, news and articles and it was possible to suggest practical strategies and insights for supply chain risk strategies for firms.

u-City projects are different with the existing urban development projects progress via convergence with IT technology. Therefore, it inheres many risk factors more than the existing development projects as including more complexity and variety. The risk management system to systematically manage those risks which get identified and quantified is required. Especially, the planning phase that is appeared the various forms has a large effect on the success of the business. However, the management of risk factors remains in the passive form. So the problems on u-City project in the planning phase and risk factors of existing development business were analyzed for the continuous growth and the successful performance of u-City project, and those risk factors was identified and quantified by using statistical technique. In the results of it, the core risk factors were obtained through which way and the basis for the effective risk management in u-City business is provided.

The construction market is diversely changing because social environmental factors are rapidly transforming. Therefore, Construction projects are becoming complex and diverse. Furthermore, the risk being inherent in construction projects are increasing, and now people are considering about the risk management of construction projects in successfully handling the risk factor. The purpose of this study is first to comprehend the preparation of basic references for objective and systematic identification, categorization, and analysis of risk. Secondly it is to find the principle elements within the risk factors identified and categorized around planning process. Finally it is to manage objectively on the planning process, which forms a lot of uncertainty, in order to accentuate the importance about the risk of pre-planning process stage

In the construction industry, not only safety accidents, but also various complex risks such as construction delays, cost increases, and environmental pollution occur, and management technologies are needed to solve them. Among them, process risk management, which directly affects the project, lacks related information compared to its importance. This study tried to develop a MATM tunnel process risk classification system to solve the difficulty of risk information retrieval due to the use of different classification systems for each project. Risk collection used existing literature review and experience mining techniques, and DB construction utilized the concept of natural language processing. For the structure of the classification system, the existing WBS structure was adopted in consideration of compatibility of data, and an RBS linked to the work species of the WBS was established. As a result of the research, a risk classification system was completed that easily identifies risks by work type and intuitively reveals risk characteristics and risk factors linked to risks. As a result of verifying the usability of the established classification system, it was found that the classification system was effective as risks and risk factors for each work type were easily identified by user input of keywords. Through this study, it is expected to contribute to preventing an increase in cost and construction period by identifying risks according to work types in advance when planning and designing NATM tunnels and establishing countermeasures suitable for those factors.

국외에서 잘 알려진 Hazus-MH, RiskScape와 같은 자연재난 리스크 모델은 위험지역 내 노출된 자산과 인구의 공간적 분포 및 그 특성을 설명하는 지형공간자료 형태의 자산정보(인벤토리)를 필요로 한다. 본 연구는 이러한 자연재난 리스크 모델 운용에 필요한 건물, 인구, 농업, 차량 인벤토리 데이터 구조를 국내에서 가용가능한 자료를 기반으로 설계하고, 이들을 연계, 변환하기 위한 툴을 개발하였다. 본 연구에서 개발된 자동변환 툴은 오픈소스로 제공되는 QGIS를 기반으로 하였고, 개발 툴을 이용하여 2018년 말 기준의 인벤토리를 전국에 대해 구축하였다. 본 연구의 성과는 현재 시범운용 중인 행정안전부 풍수해 피해예측시스템을 비롯한 자연재난 리스크 모델링 과정에 활용될 것으로 기대된다.

This study focuses on assessing risks which might occur in operation stage of CAES storage cavern and analyzing fire scenarios for the risk that have been assessed with highest risk level. Risks in operation stage were categorized into upper risk group and lower risk group. Components of upper risk group are technical risk, facility risk and natural disaster risk. Lower risk group is composed of 11 sub-risks. 20 experts were chosen to survey questionnaires. ANP model was applied to analyze the relative importance of 11 sub-risks. Results of risk analysis were compared with risk criterion to set risk priorities, and the highest risk was determined to be 'occurrence of the fire within the management opening'. Three fire scenarios were developed for the highest risk level and FDS (Fire dynamics Simulator) was used to analyze these scenarios. No. 3 scenario which air blows from tunnel into outside atmosphere represented that a rate of smoke spread was the fastest among three fire scenarios and a smoke descended most quickly below the limit line of breathing. Thus, No. 3 scenario turned out to be the most unfavorable condition when operating staffs were evacuated from access tunnel.
