The purpose of this study is to maximize project efficiencies in construction management by analyzing hierarchical factors that effect in project supervision system, and consequently constructing managerial CSF(Critical Success Factors). For this study, the tools for evaluating operating and management abilities of site engineers are built from analyzing status and issues, deducing influence factors and rating cardinal scales of these factors from survey results. These evaluation tools are reflected to the construction supervision decision making process so that can improve project management effectiveness.

The asset management of infra facilities is a total framework for finally supporting a safe and comfortable service, which includes functions of supporting evaluation of condition and performance of infrastructures, making the decision method of repair or rehabilitation of deteriorated facilities, and lengthening the life cycle of structure through the decision of adequate cost and time of repair or reinforcement. In the range of the asset management, organization, human, the target, and information & data of company are included. Therefore, in this paper, appling the method of asset management analysis to the infra structures, the process of the risk assesment using BRE (Business Risk Exposure) and the basis of consisting ORDM (Optimized Renewal Decision-Making) are expressed.

Construction projects are characterized that exposed high risks so feel strongly necessity of actively risk management that manage the time of project. but recent generally time management tools are not satisfied sufficient supporting the risk identify and risk analysis. Therefore this study purposed development the time management model that in order to improve existing problem of time management model in construction project and developed model could perform practical risk management in construction field. The new time management model focused on the risk management will be able to conduct critical path management and risk critical path management simultaneously.

With the recent rising project complexities and competitive environments in the construction projects, a risk management is recognized as more important management tool than the others. However, as most risk management techniques applied to the construction projects are centered around their initial phases and risk analyses, they are not developed into general project management technique such as time management, cost management and quality management, etc., that are usually applied in the process of construction. Thus, this paper proposes a response process to construction project risks based on the risk threshold and its calculation methodology applying a concept of VaR to establish risk management as general management technique in the construction projects.

재난발생 위험은 불확실성을 내포하고 있으며, 이러한 불확실성 요인을 줄이고 사전에 소멸시키는 일은 매우 중요한 사항이 될 수 있다. 또한 재난관리 관점에서 그것이 발생했을 때 어떤 식으로 대응할지에 대한 과정이 체계적으로 갖추어져 있어야 하며, 복구 및 재발 방지를 위한 지속적인 노력이 수반될 필요성이 있다. 본 연구에서는 기후정보를 활용한 중장기 수문예측을 실시하고 통합홍수위험평가 시스템 구축을 통한 홍수위험도 분석을 실시하였다. 이를 위하여 우리나라 243개 지자체를 대상으로 홍수관련 위해성, 노출성, 취약성 자료를 수집하여 표준화하였으며, 전문가 Delphi-AHP 설문조사 분석을 통하여 가중치를 적용하고 위험도를 예측 평가하였다. 이러한 중장기 위험 예측 정보는 한 달 또는 수개월 전에 지자체 행정력을 집중 및 분산시키고, 수재해(홍수/가뭄 등) 위험관리 계획 수립이 가능하여 재난관리자에게 유용한 정보로 활용될 수 있을 것이다. 또한 재난의 생애주기(Life Cycle)별 예방, 대비, 대응, 복구 단계에 따라 사전과 사후에 가능한 주요 활동들을 구체화 할 수 있으며, 시간 스케일별 기후예측 정보를 활용한 재난관리 패러다임 전환과 골든타임 확보 등 수자원예측 분야 기술적 진보를 이룰 수 있을 것으로 기대한다. 향후 통계 역학 모형 기반 중 장기 예측 정보의 신뢰도가 향상 된다면 보다 다양한 분야 예측 정보 서비스 및 활용이 가능할 것이다.

The endowment and concession has been put to practical use for the relocation projects of military Facilities. Yet, in terms of the project implementation, delay of a great deal of the projects is occurring due to related regulations and standards, as well as a lack of mutual understanding between project implementers and military units. This study analyzes the risk factors by identifying and prioritizing the potential risk factors at each stage of project implementation such as the issues that limit project characteristics and implementation. Among the derived risk factors, request exceeding facility standards in the licensing and design phases, opposition to troop relocation in the project approval phase, design change during construction phase in the construction and completion phases, dissenting opinions on endowed/conceded property in the property disposal phase and absence of facility standards in the MOA conclusion phase were found to be the main object of consideration in risk management. This study is expected to provide project managers with a guideline for effectively pursuing the projects, as it provides prioritization and optimization of risk management.

According to the accident statistics published by the National Police Agency in 2007, the number of commercial vehicle accidents explains 3.5 percent of the total number of traffic accidents of the year. Compared to other types of vehicles commercial vehicles may provide more serious damages to both driver himself and passengers. Thus, they generate more serious social and economic problems. There have been various forms of systems such as a digital speedometer or a black box to meet the social requirement for reducing traffic accidents and improving safe driving. However, since the current systems are based on the data often accidents happened, there are lots of limitations to control drivers in real-time. Also, the current speedometers provide drivers with only speeds of vehicles and RPM information regardless of actual dangerous drive behaviors. Therefor, they lack of the effectiveness in terms of safety. In this research, real-time information systems for improving driver safety based on automatic risky driving behaviors, and thresholds to determine risky driving patterns were studied.

The purpose of this study is to assess the risk and predict the contingency for modular plant construction projects. Considering the work characteristics of the modular plant, The adapted research method is that suggest models for assessment impact of risk and predict the contingency considering risk. Based on the proposed models, It is selected one modular plant construction project and assessment impact of risk factors and predicted the contingency. The results of this study are as follows: Assessment the probability of occurrence of risk factors and intensity of impact, and extract 15 important risk factors. These are classified as Engineering, Procurement, Fabrication, Transportation, Construction phases to consider the work characteristics of the modular plant. The predicted contingency is that 6.739%(Engineering 2.850%, Procurement 6.225%, Fabrication 6.211%, Transportation 4.165%, Construction 8.168%) to prepare the basic business expense. The model is used as a way to derive quantitative results in the decision-making process for risk management in construction projects.
