The first local exchange trading system(LETS), established in Comox Valley in Canada, aimed at facilitating the regional economy. However, in Korea, LETS was adopted to encourage mutual aid and promote community spirit among residents. This study examines the feasibility of LETS as a revitalization initiative for Pumasi and suggests a number of policies that can be implemented to support the project. The findings are as follows: First, the LETS credit system was found to complement social capital initiatives among Pumasi participants in the early stages of the Pumasi project. Second, combining LETS and Pumasi initiatives was found to consolidate community spirit and encourage a cooperative way of life among participants due to the fact that LETS enlarges the scope of local residents' participation and diversifies the services being exchanged. A number of policy suggestions are made for combining LETS with Pumasi. First, the project must define a vision of its long-term purpose and outcomes. Second, local residents should be employed as assistants to facilitate the project. Third, Pumasi participants should ensure that childcare exchange services are of the highest quality by providing an educational program on parenting. Fourth, the project manager's employment conditions and working environments must be guaranteed.

This study focuses on the BIM request for information(RFI) processing performance and quantitatively analyzes the performance of the BIM coordinator and the loss due to the waiting of the project participants. For these purposes, a method to quantitatively evaluate the performance of the BIM coordinator was proposed using a queueing model. For the verification, two projects in which BIM was applied in the construction phase were selected, and the BIM RFI data were collected through the analysis of the BIM monthly report and BIM coordinator work log of each project. In addition, the BIM input personnel, labor cost, and productivity data were collected through interviews with the experts of the case projects. The analysis of the BIM RFI processing performance of the BIM coordinator using the queueing model exhibited on a probabilistic basis that the waiting status of the project participants could vary depending on the preliminary BIM application to the design verification as well as the input number and level of the BIM coordinator personnel. In addition, the loss cost due to the waiting of the project participants was analyzed using the number of BIM RFIs waiting to be processed in the queueing system. Finally, the economic feasibility analysis for the optimal BIM coordinator input was performed considering the loss cost. The results of this study can be used to make decisions about the optimal BIM coordinator input and can provide grounds for the BIM return on investment (ROI) analysis considering the waiting cost of the project participants.

The objective of this study is to investigate actual conditions of terrestrial vegetation part in Environmental impact statement, and to prepare a proposal for the efficiency of Environmental Impact Assessment. 13 E.I.S.s made out during 1996.6-1997.5. have been chosen and analysed with respect to scope of survey, item of survey, method of survey, and result of survey. Actual conditioins of terrestrial vegetation part in E.I.S. are summarized as follows : 1. The mean number of total participants in drawing up E.I.S. is 26.0 persons, that of participants in terrestrial vegetation part is 2.3 persons. 2. In case of planar project, the mean of scope of survey is 16.1 times as large as area of project . In case of linear project, the scope of survey has been determined arbitrarily. 3. The most part of survey has been dependent on literature, and field survey has been practically neglected. 4. Results of survey mostly missed the point that E.I.A. pursues. And proposals are as follows : 1. Participants in terrestrial vegetation part in drawing up E.I.S should be increased. 2. It is necessary to subdivide scope of survey in view of difference between planar project and linear project. 3. As for item and method of survey, field survey should be specially reinforced. 4. Several sheets of map as results of survey should be included in E.I.S. The vegetation map, the D.G.N. map, and the planting map should be included and drawn by smaller scale as possible.

Recently, intensive urban redevelopment concentrated on new towns has reduced the number of settled population, and weakened various functions such as commercial, culture, education and welfare in old towns, and made the stagnation and declination of the entire or some parts of old towns. Urban regeneration project means renewing cities' functions in terms of physical, environmental, social, cultural, industrial and economic aspects or revitalizing the existing functions through improvement project in the entire or part of a city, which is now drawing keen attention from the public. However, urban regeneration project is huge in scale, needs long construction period and various complex facilities, and also characterized by complicated relations with many stakeholders. Due to such characteristics, there are many risks in the project. Therefore, systematic risk management is absolutely necessary to efficiently manage various risk factors inherent in urban regeneration project. The purpose of this research proposes a basic model to establish risk management plan and work process in order to help project participants to perform risk management more systematically and rationally in the development phase of urban regeneration project.

As a recent global trend, the majority of mega-size plant projects are delivered through EPC (Engineering, Procurement and Construction) contracts, where a single contract is awarded for engineering, procurement, and construction. Under this contracting mechanism, it is challenging for contractors to carry out the projects under traditional project management processes used in design-bid-build projects. A new EPC Plant, the POSCO Special Steel Plant in Changwon, was built successfully at the beginning of 2012 and it is currently in full-scale production. The project has encountered a number of major difficulties however, with some technical and managerial issues through its development process. As summarized in this paper, the authors (as project participants with the contractor) investigated it as a post construction analysis and recorded the Lessons-learned for future project management improvement.

The Korean government makes an effort to raise the competitive power of nation through CM activation in the construction industry. Since the first CM service was applied to the atomic power plant project in 1986, the number of CM contracts are continuously being increased and will be up to 20% by 2002 in public sector. However, the public projects had been executed without any procedure manual or standard guideline of CM services. Meanwhile the Ministry of Construction and Transportation issued $\ulcorner$CM Service Guide$\lrcorner$, but the guide shows an indefinite description in the responsibility, authority and scope of activity for the project participants. Therefore, it is required the procedures be improved and scope of activities be established for the project participants. This study was generated from the comparative analysis of $\ulcorner$Standard CM Services and Practice$\lrcorner$ Published by CMAA and domestic $\ulcorner$CM Service Guide$\lrcorner$ and the case of Incheon International Airport construction. The purpose of this study is to provide the fundamental data for an improvement in the procedures of project execution and the construction manager's activities/rolls shown on $\ulcorner$CM Service Guide$\lrcorner$

BIM is effective to improve the labor productivity of construction participants. From this point of view, it is important to analyze the outcome related with BIM Labor which covers most of the BIM investment costs. This research focuses on BIM RFI which is one of the major task of the BIM labor and analyze the outcomes. In addition, this research was quantitatively analyzed by the standby time and related cost caused by BIM labor, which affect the results of the project participants. To this end, analytical standby queue model was utilized to analyze the labor focusing on micros TASK. 11 projects were selected to analyze the results of BIM labor and RFI that the project participants requested to the BIM labor was collected. Through this, it collected variables for analyzing results, and Finally, we pulled out 4 projects for analysis. In this study, the basic results analysis of RFI processing of the BIM labor, the probabilistic analysis of BIM labor service status, and the economic analysis of BIM labor optimal inputs were performed by using the research model presented. The results of this study can be utilized to formulate the optimal strategy for BIM labor inputs(e.g. number of employees, level, time point, etc.) of the construction phase. Moreover, it can contribute to ensuring the credibility of the BIM ROI results by presenting the cost of BIM services in BIM ROI analysis and the standby cost of project participants.

Recently, Information System (IS) development projects such as the next generation IS project of the financial business domain have shown tendency to become large and complex. Accordingly, a large number of enterprises have introduced a Project Management Office (PMO) to successfully manage multiple complex large-scaled projects. Many researches and empirical studies have proved the positive results of PMO-based projects. For example, most PMO-based projects have been accomplished successfully without exceeding the planned deadline and budget. However, even in the case of PMO-based projects, participants are still supported by legacy Project Management Systems (PMS) developed without considering the PMO. It implies that recent large projects are hardly performed efficiently because of the large gap between the legacy PMS tools developed only for single small projects and the real process of PMO-based project management. Therefore, we attempt to design and develop a PMO-based PMS in which the role and responsibility of PMO are completely implemented. To demonstrate our systems practicality, we applied the devised system to the real project management cases of "K" bank in The Republic of Korea. According to the results of case analysis, all of the four projects supported by our PMO-based PMS have been completed without exceeding planned deadline and budget, and the quality of their final outcome is appraised to be superior.
