Nuclear power plant site selection is a complex process and its successful completion is a critical milestone in the NPP development cycle. Proper siting of NPP will ensure public health and safety, environmental conservation, reduced project failure risks and a smooth NPP development process among other benefits. The objective of this paper is to demonstrate the application of systems engineering to the problem of NPP siting in Kenya. The siting process demonstrated in this paper includes stakeholder need analysis where stakeholders are identified and their needs concerning NPP site are elicited and converted into system functional requirements. A value model is then developed and potential sites iteratively subjected to three types of criteria i.e. exclusionary criteria, avoidance criteria and suitability criteria. This process is used to identify the candidate sites. An additive value model; multiple objectives Decision Analysis (MODA) is then used to calculate candidate solutions values. The site with the highest solution value score is selected. Sensitivity studies using different criterion weight sets (thereby reflecting different viewpoints) can be conducted to assess their effect on the selection of a preferred site and thereby lend additional credibility to the decision process.

Failures of super large projects like IT Upgrade of Shinhan Financial Group can be a heavy blow not only to the company but even to the national economy. Research on the practices of risk management in those projects will provide invaluable lessons, enhancing capabilities and chances of successfully executing mission critical projects of the companies and the national economy as a whole. This paper analyzes the risk management of the Core Systems Reconstruction which was the most critical component of IT Upgrade. The analysis covers risk management plans, and identification and evolution, and control and monitoring of risk factors. This study confirms the major results of previous research on risk management in Korea. However, the analysis found as well some discrepancies of practices from the previous research results. This research also tracked the trajectories of evolution of risk factors and management. In particular, in depth analysis of control and monitoring is the first research in Korea on the "management" of risks in IT projects. The result of this research is expected to be a useful guide for theory development and practices of risk management in the future.

건설공사의 불확실성은 빈번히 클레임에 노출된다. 대부분의 경우 이러한 클레임에 대한 기본적인 해석은 공사계약서를 기준으로 하게 된다. 이러한 계약서 작성시의 문제는 발주자나 시공자가 부담하여야 하는 계약적 위험(risk)이 어떻게 규정되어 있어야 합리적인 수준인가를 판단하는 것인데 이러한 판단을 위해서는 FIDIC 계약조건과 같이 국제적으로 합리성을 인정받는 표준계약조건을 참고하는 것이 합리적이라 하겠다. 이에 본 연구는 FIDIC 계약조건을 기준으로 국내 공공공사에서 일반적으로 사용하는 공사계약일반조건에 내재되어 있는 불공정, 불합리 조항을 분석하여 세계적 수준에 맞는 공사계약조건을 제시하고자 위험관리의 관점에서 공사 계약조건을 분석하고, 여기서 도출되는 위험요인을 검증하며, 이에 대한 대응방안을 모색함으로써 공사계약일반조건의 위험요인 감소방안을 제시하고자 한다.

Government spending on research and development increased continuously is much more important to decision-making methodology for rational investment. Rely on a group of minority experts in the application of a general methodology, a tipping effect occur in specific technology field or difficult balanced procedure and objective control to maintain. This paper presents a qualitative-quantitative methodology to avoid such risks by utilizing Technology-Tree pertaining to energy R&D planning of the government Energy Technology Development program. Especially Energy Technology Development program "energy storage system" is applied to the analysis of Technology-Tree, mapping and analysis of existing government-supported projects during the recent 5 years, is derived essential missing elements of the technology value chain. This study suggests that significant evidence is utilized for improving efficiency of government R&D budget considering the importance of technology, domestic research-based and so forth, could be used to implement the R&D project planning.

Singapore, a city state with less than 6 million population, has continued successful cooperative development and become one of the most successful Asian countries in exporting expertise in urban and real estate development. This research aims to analyze Singapore's cooperative development with socialist countries including China and Vietnam from Singapore's perspective as an investor. For cooperative development projects in China, Singapore adopted Singapore-style physical urban planning concepts as well as its own institutional and administrative systems. Singapore-Vietnam cooperative development managed to acquire profitable land and diversify its portfolio in terms of industry types and rents. This made Singapore's industrial parks more competitive than other parks in Vietnam. By showcasing successful project implementation in China and Vietnam, Singapore has proved that its model for industrial park and urban development is transferable. Singapore's success in cooperative development with socialist countries provides important implications for future cooperative development between South and North Korea. For example, phased development approaches starting from individual industrial parks expanding to mixed-use townships will be very useful to realize sustainable urban planning in North Korea and reduce financial risks. Singapore dominated development opportunities in advance when socialist countries opened their economy. To pattern ourselves after Singapore, we should not only improve our relationship with North Korea but also prepare with practical components such as financing and organizational structure.

CCS (Carbon Capture and Storage) is considered as the most promising interim solution to deal with the greenhouse gas such as $CO_2$ responsible for global warming. Even though carefully chosen geologic formations are known to contain stored gas for a long time period, there are potential risks of leakage. Up to now, applicable risk assessment procedures for the leakage of $CO_2$ are not available. This study presents a basis for risk analysis applicable to a complex geologic storage system. It starts with the classification of potential leakage pathways. Receptors and the leakage effect on them are identified and quantified. Then, a fault tree is constructed, which yields the minimum cut set (i.e., the most vulnerable leakage pathway) and quantifies the probability of the leakage risk through the cut set. The methodology will provide a tool for risk assessment in a CCS project. The outcomes of the assessment will not only ensure the safety of the CCS system but also offer a reliable and efficient monitoring plan.

As a future clean substitute energy, the Gas hydrate development projects are world widely carried out to prepare the shortage of petroleum and natural gas resources. The OIIP of gas hydrate is estimated approximately 10 Trillion LNG equivalent ton and it reaches almost the amount of 5 thousand years use for the world people. To develop the commercial production technology, several research projects like Malik and Alaska project have been carried by several advanced countries and teams, but nobody have succeeded it yet due to the technical problems and the high risks. The technologies developed up to now for the hydrate production are categorized to four methods, such as depressurization method, thermal recovery method, inhibitor injection method and replacement method. As these methods are highly related to the costs and the environmental problems, many other researches including the safety, environment and disaster prevention are actively fulfilled as well.

Larger and more sophisticated building construction requires more input resources such as worker, materials and devices. Growing resource volume brings risks at a construction site. The industry makes an effort to protect probable incidents at the site by organizing a safety management team. conducting a safety instruction and etc, but losses especially in the construction are higher than other industries. Major reason is that the safety management program is conducted only at the step of construction work and a root cause is not eliminated. Conventionally a concerned party shifts the blame to other parties such as constructor and site workers who are direct participants in the construction site. However, the whole causes of incidents go to the all subject of the construction not only the constructor but the client, designer and others related in the construction, and especially the clients are heavily involved in general concerns of the project. Therefore, this study is defined the role of the clients in nations and domestic condition of construction safety management is investigated. And it is analyzed surveys to prevent incidents at construction sites, and suggested the role of the clients which is classified pre and post construction, and in the middle of construction, and also categorized planning and design & construction schedule especially for the pre-construction level.

Adoption and practical application of BPM yet remains at a theoretic and methodological level for many industrial sectors. As for construction industry, adapting BPM into enterprise resource across all business processes could cause problems due to rapid change in corporate operation systems. Furthermore, it is unable to predict potential risks of business process while BPM are being applied. Therefore, applying BPM model to core strategy and individual task seems more effective than applying BPM model to the entire enterprise resource planning. In this paper, we define BPM and suggest a BPM model by analyzing each business unit in order to evaluate each business unit which is included in the business process architecture based on quantitative standards. This paper also presents a sequential application plan for business process model. Finally, a case study is demonstrated for the application of BPM system, focusing on cost management business, which turned out to be a top priority in the aspect of efficiency and ease based on priority analysis.
