The employment of risk management theory in Urban Disaster Management System (UDMS) has become an important trend in recent years. The viewpoint of risk management is mainly a comprehensive risk assessment of various internal and external factors, and a subsequent handling of risks. Through continuous and systematic accumulation and analysis of risk information, disaster prevention and rescue system is established. Taking risk management theory as the foundation, Organization for Economic Cooperation and Development (OECD) has developed a series of UDMS in the mega-cities all over the world. With this system as a common platform, OECD cooperates with different cities to develop disaster prevention and rescue system consisting of vulnerability assessment methods, risk assessment and countermeasures. The paper refers to the urban disaster vulnerability assessment and risk management of OECD and the mega-cities of different advanced and developed countries in the world, and then constructs a preliminarily drafted structure for the vulnerability assessment methods and risk management mechanism in the metropolitan districts of Taiwan.

최근 국내외에서 도시재생사업이 활발히 진행되고 있다. 이러한 도시재생사업은 사업주체 및 이해관계자가 다양하고, 복잡하며, 대규모의 긴 생애주기를 가지고 있다. 또한 대부분 입체 복합공간 개발 형태의 메가프로젝트라는 특징을 나타내고 있다. 이러한 대규모의 도시재생사업은 사업수행과정에서 많은 위험요인들이 존재하며, 그와 더불어 효율적이고 지속적인 성과관리가 필요하다. 그러나 국내의 성과관리는 건설업의 특성을 반영하지 못하고 있으며, 위험과 연계된 연구는 미비하다. 그래서 본 연구는 효율적인 성과관리를 위한 위험과 연계된 성과측정지표를 도출하기 위한 기초연구로 맵핑(mapping)을 통해 성과측정을 위한 성과지표와 위험요인을 연계하는 방법을 제시하고자 한다.

For the success of system development, it is necessary to systematically manage the requirements that are the basis of system development and its verification results. In order to follow the principles of SE(Systems Engineering)-based V&V(Verification&Validation) process, requirements can be managed by securing the requirements and their establishments, design compliances, and verification compliances according to the system development lifecycle. Especially, in a large-complex system research and development project, such as a space launch vehicle development project, many participants establish, verify, and validate numerous requirements together during the project. Therefore, logical and systematic requirements management, including guarantee of data integrity, change history, and traceability, is very important for multiple participants to utilize numerous requirements together without errors. This paper introduces the practical requirements and verification management for the requirements-based development process in the space launch vehicle development project.

A severe problem in VE study of a project is to reduce value due to loss of performance, caused by focusing on cost reduction. Also a lack of understanding performance concept, no trial VE workshop as well as cost saving-based policy have not satisfied customer needs. A efficient VE job plan for especially large scale railroad construction project is proposed in this study. This study developed a more objective performance evaluation system for value engineering study of mega projects and suggested a systematic process of performance quantitative analysis for value improvement. The proposed performance measurement method would be very useful for better communication and consensus between decision makers and VE team.

Today's construction is a large-scale and long life span program, so called Mega-scale project, that every moment constructor faces much of hardships, It is because of a large amount of stakeholders, data and complicated relationship among workers. In order to overcome these problems, IETM(Interactive Electronic Technical Manual) has been introduced to construction industry recently, It is regarded as a useful tool for handling the data, procedures of the construction, but it is similar to existing IT-based information systems, the PMIS(Project Management Information System) and the KMS(Knowledge Management System), without characterizing. This research is intended to find out IETM's property and to present the Ontology scheme discriminating Construction IETM from existing systems..

In 2006, Korean Government decided to relocate the several Government bodies and public institutes. They include total of 49 central Government agencies, semi-government agencies, and 17 national research institutes. The completion of the relocation program has been set to be final in 2030. The target population for the city plan is set to be 500,000. The goal of MAC is first to complete the first phase of the program by 2014 within the budget. In order to achieve the goal, considerable time has been spent to properly establish the program management system. The success of MAC's Multi-function Program Administration System is too early to determine as it is still in progressive. The success depends on the operations not the development.

In proportion to continuing growth of overseas plant market and the trend of its mega scale of the project, the importance of management is significantly emphasized for the successful execution of the project. And it is recognized that progress control is the most important management item amongst the others in the management. Progress control is importance of progress measurement for performance measurement and process control of project, but it is hardly obtainable securing the objectivity in the progress measurement since the progress measurement are being applied differently in accordance with the project conditions and the experience level of the person in charge for the progress control. This study has conducted as following to propose a standard method for progress measurement in a petrochemical plant protect. Domestic and overseas plant projects are investigated variously with the applied method of progress measurement, and the deduced problem of progress measurement. And then standard method for progress measurement of engineering, procurement, construction and commissioning has been proposed according to comparison and analysis of practices in domestic & overseas plant project, procedures for progress control in the globally reputed petrochemical client, company rules and recommendation of the expert in progress control.

With Beijing's success in bidding for the 2008 Olympic Games, the increasing demand for infrastructure development and reduced public sector funding capacity has created a significant funding gap which calls for alternative project delivery methods such as Public-Private Partnership (PPP). Although the exploration of infrastructure projects using PPP model have been practiced since the late 80s, the $560 million National Stadium which served as the main venue for the Olympic Games is the first stadium project in China to be delivered under PPP operation. The project is generally considered successful despite the concession transfer in 2009 with concern of better serving the public interest. Compared to other infrastructure projects such as transportation, waste management and water management, the development of major sports facilities for mega-sports events with PPP has its own unique features and is subject to different major risks. This research identifies and analyzes critical risks in the implementation of PPP in major sports facility development through case study of the National Stadium project. A questionnaire survey and several interviews are conducted to solicit expert opinions from experienced practitioners. The purpose is to provide additional insights in risk management strategies and opportunities in China's PPP implementations in major sports facilities for policy makers and private sectors involved with investment decisions in future similar infrastructure development.

공기지연이 발생하게 되면 그에 대한 추가적인 비용이 발생하게 되어 사업비의 증가를 초래하기 때문에 발주자와 시공자의 분쟁을 유발하는 중요한 원인이 된다. 공기지연으로 인해 발생한 분쟁의 원활한 해결을 위하여 공기지연분석에 대한 다양한 연구들이 수행되어져 왔으나, 기존의 공기지연 분석방법들은 주로 소규모 건축공사와 같은 단순하고 반복적인 공정들에 적용되는 연구들이 대부분이어서 경부고속철도와 같은 대규모의 선형적인 복합 건설공사에 적용하기에는 한계가 있었다. 본 연구에서는 이러한 전통적인 공기지연분석방법을 대규모 토목공사에 적용할 수 있도록 보완하여 대형 건설공사의 공기지연을 전체 프로젝트 관점에서 입체적으로 분석하였다. 먼저, 거시적 차원에서 공정진척도(S-curve)의 비교분석 등을 통해 공기 지연이 가장 많이 발생한 공구(공사구간)를 찾는 분석을 실시하였다. 이어서 거시적 분석으로 도출된 지연공구의 일정공정표를 분석하여 지연원인과 그에 따른 영향분석을 실시하였고, 지연원인의 책임소재에 따른 분석과 구조물 특성에 따른 분석도 병행하여 공기지연의 특징을 입체적으로 분석하였다. 이러한 다면적인(multilateral) 공기지연분석을 통해 경부고속철도의 개통일정을 지연시킨 가장 주된 구간은 서울~천안의 "2-1공구"인 것으로 나타났으며, 전체 약 5년의 공기지연 중 4년여의 공기지연이 이 공구에서 발생한 것으로 분석되었다. 주요 공기지연 원인으로는 최초 설계시 고속철도 교량의 동적거동을 고려를 하지 못해 재설계와 재시공으로 공기가 지연되었으며 또한 불충분한 지질조사로 시공 중에 폐광이 발견되어 노선변경을 했던 것에 크게 기인하는 것으로 나타났다. 마지막으로 경부고속철도에 대한 공기지연분석을 통하여 이와 유사한 대형 국책 사업의 계획에 있어서 고려해야할 사항을 제안하였다.
