Increasingly, risk analysis is becoming important ingredients in achieving the successful implementation and application in the area of the project management. The project management system is designed to manage or control the project resources on a given activity within time, cost and performance so called TPPM (Total Productive Project Management). In this research, a risk analysis model misproposed to identify potential problem areas, quantify the risks, and generated the chice of the action that can be taken to reduce the risk. In addition two analysis models are proposed : 1) risk factor model and 2) network simulation model using VERT (Venture Evaluation and Review Technique ). The objective of the remodels is to estimate the schedule, cost performance risks. These proposed quantitative models for project risk analysis are proving its value for the project managers who need to assess the risk of changes in cost, schedule, or performance. The proposed models will be used in the area of project selection, evaluation and the allocation of project resources.

Integrated management system (IMS) for sewerage facilities has been installed at 7 dams and 9 watersheds since 2006. However, there has been no decisive plan on how and who to manage efficiently IMS after finishing the construction. Therefore, in this study, it was suggested that a new organization, so to speak, a technical support team for integrated management that may operate and manage IMS efficiently, could need to be set up. Three scenarios were evaluated depending on the type of allocating human resources to new organization considering each levels of sewerage facilities. Economic analyses on each scenarios of human resources allocation were also carried out. As a result, establishing the technical support team for integrated management was estimated to give the net benefit from 1.3 billion to 20.6 billion won for 15 years.

Increasingly, leisure time is being used for outdoor recreational activities, and fishing is one of the principal forms of marine recreation. Marine recreational fishing is a popular activity in Korea and this activity has led to the development of a sector of substantial social and economic value. Also it is considered as one of the important outdoor leisure industries in Korea. With rising of income level and development of marine outdoor leisure industries, social, economic demand increase of marine recreational fishing are showing us new advance ability of marine aquatic bio-industry. However the recreational use of fish stocks has become an important consideration in the public and environmental economic analysis of management aspect of fishing, having grown considerably over recent years to reach a level in Korea where the fish stocks and coastal ecosystem has become a significant management problem. we are inevitably facing marine environmental deterioration and overfishing in marine recreational fishing. In this study, not only resources and environmental problems which are occurred by recreational fishers, but also illegal fishing behaviors and other problems such as market's failure are going to analyze basic management theories and methods of recreational fishing through mathematical principals and economic rents which maximize net social benefits. In view of the likelihood of marine recreational fishers adopting high rates of discount, the conservation of fish resources would appear to require continual public surveillance and control of the physical yield and condition of the fish stocks and the optimal use level. The institutional management of recreational fisheries is the way of escaping the collapse of recreational fisheries just like as the situation of management's failure of commercial fisheries worldwide. One of the effective management measure is a license system. In this system, optimal fee is paid by recreational fishers, which prevent them from overfishing, environmental problems to some extents and carry out the optimal number of outings. And money obtained by license fee should be spent for more improvement fishing culture and welfare for marine recreational fishing. Marine recreational fishing is to be promoted under sound conservation and management principles.

A system to analyze, assess and manage the health performance of resources and spaces throughout the project lifecycle shall be established to ensure sustainable healthy buildings. Decisions made in the planning, design, construction, and operation and management (O&M) phases must help sustain the health performance of buildings at the level specified by clients or the relevant laws. For this reason, it is necessary to develop a model to ensure the consistent management of performance, as such performance varies according to the decisions made by project participants in each phase. The purpose of this research is to develop a Lifecycle Health Assessment Model (LHA) for sustainable healthy buildings. The developed model consists of four different modules: the Health-friendly Resources Database (HRDB) module, which provides health performance data regarding resources and spatial elements; the Lifecycle Health-performance Tree (LHT) module, which analyzes the hierarchy of spatial and health impact factors; the Health Performance Evaluation (HPE) Module; and the Lifecycle Health Management Module, which analyzes and manages changes in health performances throughout the lifecycle. The model helps ensure sustainable health performances of buildings.

This study was conducted in the spring of 2005 through personal interviews to examine the opinions of forest products manufacturers and consumers about the perspective of forest certification in South Korea and to characterize those consumers who expect the activation of a forest certification system in South Korea. Study results indicated that consumers showed more positive aspect for the activation of forest certification than forest products manufacturers. Respondents who had a negative view for establishing a forest certification system in South Korea pointed out a lack of customers' demand for certified wood products as the most important reason. Results also showed that, even when a forest certification system would be introduced as a possible policy for helping to attain sustainable forest management, it would take at least 5 to 10 years to establish a forest certification system in South Korea. To facilitate the establishment of the system, many respondents suggested that an increased public awareness of forest certification systems was the most required precedent condition, and government for manufacturers and forest management association for consumers had to certify forest management practices as a competent organization. A profile of consumers who expected the activation of a forest certification system would describe in relative terms as the highly educated female who interviewed in the city of Seoul and of the 20 age bracket. Although there were an increased public awareness and positive prospective of forest certification by consumers and forest products manufacturers, it is required to arouse much more interest of consumers about the system.
