Risk identification for bridge projects is a knowledge-based and labor-intensive task involving several procedures and stakeholders. Presently, risk information of bridge projects is unstructured and stored in different sources and formats, hindering knowledge sharing, reuse, and automation of the risk identification process. Consequently, there is a need to develop structured and formalized risk information for bridge projects to aid effective risk identification and automation of the risk management processes to ensure project success. This study proposes a semantic risk breakdown structure (SRBS) to support risk identification for bridge projects. SRBS is a searchable hierarchical risk breakdown structure (RBS) developed with python programming language based on a semantic modeling approach. The proposed SRBS for risk identification of bridge projects consists of a 4-level tree structure with 11 categories of risks and 116 potential risks associated with bridge projects. The contributions of this paper are threefold. Firstly, this study fills the gap in knowledge by presenting a formalized risk breakdown structure that could enhance the risk identification of bridge projects. Secondly, the proposed SRBS can assist in the creation of a risk database to support the automation of the risk identification process for bridge projects to reduce manual efforts. Lastly, the proposed SRBS can be used as a risk ontology that could aid the development of an artificial intelligence-based integrated risk management system for construction projects.

Purpose - As the well-known Structure-Conduct-Performance paradigm implies, risk structure of a corporation may affect its risk management activity and the activity may in turn determine its performance. Depending on its goal, Foreign Direct Investment (FDI) can shape its risk structure, risk management and its performance. Under this assumption, we investigate the relationship between the goals of FDI and risk management for the first time in academics. Design/methodology - This empirical research uses a survey of 279 current Korean enterprises' FDIs in China with the recently developed business risk quadrant model. Companies are classified into either a market- or an efficiency-seeking group, to identify how each group perceives and manages risks, and values the performance of risk management. Also, we apply integrated risk management method that multinational corporations have introduced in China, then verify the mediating effect between risk factors and performance. Findings - Our research shows the FDIs can expose themselves to differing risk structure although risk management activities simply represent the level of empowerment given to local management by headquarter due to limit of sample size despite diversity of risk and risk management tools. To sum, market seekers are found to have more strategic risk (revenue related risk) than efficiency seekers with financial risk (cost related risk). The market seekers can manage their risk by empowering their local organisation while the efficiency does the opposite ways. The risk management appears to be successful in general. Originality/value - Previous studies on small and medium enterprises' FDIs to China have concentrated on the analysis of entry determinants, withdrawal factors and individual risk management. Meanwhile, this research establishes enterprise-wide risk factors faced by the companies that advance into China, according to the method of the classification by ERM and verifies if they could synthetically improve performance through risk corresponding measures.

It is very important the collaboration and risk management of supply chain between the parent company and its partners in the supply chain risk management(SCRM). It was known that the SCRM approach is very different between a large enterprise and a small and medium-sized enterprise. This paper deals with the suggestion about SCRM structure for a small and medium-sized enterprise. This SCRM structure consist of risk identification, risk assessment, and risk mitigation. We expect that this SCRM structure promote the collaboration between a parent company and its partners to alleviate the supply chain risk.

본 연구에서는 리스크관리 인자별 중요도와 4D 객체 시각화방법론을 통한 리스크관리 정보의 시각화 모델을 제안한다. 리스크관리 프로세스 모델은 WBS(Work Breakdown Structure)와 RBS(Risk Breakdown Structure)를 통해 구성되며, RBS에서 분류된 리스크 인자는 퍼지 분석기법을 통해 중요도(Weight)가 분석된다. 이 중요도는 4D 시각화를 위한 건설공사 객체(Object)의 속성 데이터로 지정된다. 또한 Object의 4D 시각화를 위한 방안으로는 4D 시뮬레이션기법이 활용되며, 등급별로 구분된 리스크 인자의 중요도와 4D 시뮬레이션을 통해 직접적인 건설공사 부위별 리스크관리 수준 확인과 부위별 리스크 인자의 시각화가 가능하도록 하는 방법론을 제시한다.

전통적으로 금융기관이 전자금융을 취급하는 과정에서 제기되는 여러 가지 위험을 경감하기 위한 다양한 수단을 가지고 있지만, 인터넷의 활성화로 인해 새로운 전자금융의 위험이 제기되고 있으나 이에 대한 대응방안과 정책수단에 대한 연구는 미미한 실정이다. 인터넷이 사회적으로 광범위하게 확산되고 이용이 활발해짐에 따라 금융기관에서도 전자금융운영시스템을 인터넷중심으로 바꾸고 있다. 이 과정에서 온오프라인 겸영은행의 전자금융이나 인터넷전문금융기관의 전자금융의 경우 인터넷이 지니고 있는 고유한 특성으로 계좌개설에서 제기되는 새로운 위험이나 아웃소싱과정에서 제기되는 위험 등 새로운 위험이 제기되고 있다. 이러한 위험에 대응하기 위해서는 전자금융위험관리방식을 체계화할 뿐 아니라, 해킹방지, 고객보안강화 등 기술적 물리적 대책도 필요하며 체계적인 아웃소싱위험관리기준의 마련 등 다양한 대응책의 마련이 요구된다.

This study outlines possible risk factors in the SCM of a company and correlates risk assessment, the strategy of risk management, and the supply chain performance. The data is surveyed from an international Korean company and is analyzed by the structure equation model of actual proof. The research model verifies the correlation between the risk assessment, the strategy of risk management, and the supply chain performance as dependent variables after the risk factors of the SCM are defined as independent variables. The research shows that there are consecutive links among the risk factors of the SCM, the risk assessment, and the strategy of risk management. The strategy of risk management was conclusively determined to have an effect on supply chain performance. Therefore, improving the supply chain performance of a company requires the constructive process for risk management based on a correlation between risk assessment and the strategy of risk management.

For the continuous growth of firms, the contributions of effective risk management system are required. This research analyzes the impact on the firm's performance related to risk management structure which includes the risk management system, risk management activity and risk management competency. In this research, the structural equation model considering the variable which contains enterprise risk management system, risk management activity and risk management competency was suggested. Also risk management organization and management procedures are identified as in enterprise risk management system. The implementation activity and control activity were the factors related in risk management activity. And risk management competency can be described as the response level of managing risk in outside and inside the firms' environment. Finally this model was analysed empirically for 112 firms in Korea using SPSS 18.0 and Amos 16.0. As the results, the suggested hypothesis were adopted. So as to manage risk performance for their firms, the development of systematic Risk Management Framework is important for their risk management activity and risk management competency. Ultimately, we can conclude that the focusing to the systematic risk management approach could be effective on the firm's risk management performance.

The study examines the effects of growth opportunities, debt maturity and liquidity risk on leverage, making use of a large panel of Chinese listed firms. Research on capital structure has broadened its scope from a single capital structure decision (the debt/equity choice) to various attributes of the debt in firms' capital structure. We use the system Generalized Method of Moments estimator to control for unobserved heterogeneity and the potential endogeneity of regressors. We find a negative relationship between growth opportunities and leverage. Further, we find that while the proportion of short-term debt attenuates the negative effect of growth opportunities on leverage, it negatively affects leverage as predicted by the liquidity risk hypothesis. When we distinguish between state owned firms and private controlled firms, we find evidence that these effects are only relevant to private controlled firms. However, our analysis indicates that the economic implication of liquidity risk effect is much lower for Chinese firms than that observed in the literature for US firms. Our study suggests that these differences can be explained by differences in the institutional environment in which firms operate. This finding related to Diamond's (1991) liquidity risk hypothesis extends our understanding of the relationship between liquidity risk and the debt maturity choice.
