The Sustainable Water Resources Research Center (SWRRC) was established to manage water resources in an integrated manner and has been supported as a part of the 21st Frontier Research and Development Program by the Ministry of Science and Technology (MOST) and Ministry of Construction and Transportation since August 2001. The mission of the SWRRC is to cope with future water shortage problems through development and implementation of technologies of integrated water resources management. This mission ultimately aims at improving of living standards of human being, which is one of the major goals of the 21st Frontier Research and Development Program. The project is conducted by three phases. Duringthe first phase (2001. 8 ~ 2004. 6), the majority of funding is used for development of core and supporting technologies. In the second phase (2004. 7 ~ 2007. 6), with the core and supporting technologies financed continuously, the fund will be usedon different parts of studies in terms of sectors, subjects and integrated researches, and the rest of the fund (50%) will go toward implementation combined with business in the form of providing technologies. In the final phase (2007. 7 ~ 2011. 6), 30% of the fund will be used to integrate developed systems and 70% will be spent on implementation for selected areas to which newly developed technologies will be applied Project Management System for Water resources R&D is cost-effective and well fitted system by resolving many kind of problems facing such a large research and development program considering limited manager.

KEPCO has expanded electrical facilities to the largest scale to cope with electrical demand that over 10% increases per annum during last four decades, and marked herself in the world as an advanced power company by recently opening a new era of 765kV transmission system, the first among East nations to do so. Particulary, KEPCO has a big global competitive edge in accumulated knowhow and also with highly experienced specialists groups in every field. KEPCO is taking advantage of it's experience and has been knocking on the door of the overseas market since 1993. Success could be seen in the power generator in Philippines and other nations, and also the accomplishment of the successful first project of transmission part, Myanmar Power System Analysis. Based on that, KEPCO developed the second stage of the Myanmar project, Basic Designs for the 500kV Transmission System in Myanmar, and commenced it in January 2004. KEPCO would like to take this opportunity to find business advance strategies which coincide with the special quality of the transmission field, and not only techno-service businesses but also find a way out of transmission business field, which is already facing a slow down, by cultivating oveseas markets of huge constructing business with domestic companies. In connection with that, this paper is trying to find a cooperation system between KEPCO and domestic companies, and an effective project management method.

Construction industry became huge and complicated as the time went by. It has been so rapidly developed that the construction companies can not survive in the market if the higher technology and scientific approach are not applied. Especially in the field of construction management, it started from the schedule control which simply monitored the work progress, but now it was changed to the integrated construction management covering analysis and forecasting, projected and actual performance management, impact on the project, etc. However, even the integrated construction management has a limit due to the uncertainty arising out of fast track which is a major characteristic of construction industry. So, to minimize the risk of uncertainty, a new concept so-called 4-D CAD system was recently introduced. 4-D CAD system has been applied to design, construction and construction management. The system combines the 3-D CAD system with time management technique that makes it possible to establish the management system with a concept of space, materialize the potential risks, and introduce the life-cycle concept in the whole process covering project initiation, design, construction, completion, commissioning, etc. This paper introduces the 4-D CAD system, reviews the effect and problem arising when applying the system into actual job sites, studies the usage of the system in connection with the conventional construction management system and any improvement, and eventually proposes the method of improving the construction management in domestic projects and of leveling up the construction management technique.

Construction Management(CM) that is the business innovation and method of construction management is introducing and implying the needs to improve high cost and low productivity structure and cope with very variable changes of construction market in construction industry within the country. But, safety management system is a very insignificant thing under CM. Consquently, We had been needed for the improvement about what the problem was. Therefore, My study raised the problem to the system and management by making a comparative study of the feature of the management method and the content of the accomplishment of safety management by using the consideration of the case about a big field of construction work implying CM within the country and proposed the active method of safety management.

This study suggests a safety management model for construction management (CM) suitable to domestic conditions so that inefficiency resulted from the operation of construction projects by public and private institutes according to different systems can be eliminated for the securing of systematic and efficient safety management. Based on the suggested safety management model, this study also develops a safety management information system that can efficiently and consistently manage and maintain a large quantity of information, and give necessary supports in a speedy way in the managing of construction projects.

Construction Management(CM) system, which was introduced some years ago to large national construction projects, such as the construction of Incheon New Airport, construction of high-speed railroad and World Cup stadiums, is considered to be still in its early stage and safety at each step of CM is very poorly controlled. In an attempt to improve such inferior safety management of domestic CM, this study made comparative analysis about operation system of safety management with CM system in domestic and abroad. Also suggested the model under consideration with CM, which is suitable for the situation of Korea.

The levels of sanitary management procedures in university and industry foodservices, in pusan, were investigated. The questionnaires were administed to ninety three dietitians who managed university (n=21) and industry (n=72) foodservices and then the data were statistically analyzed. When sanitary management procedures were evaluated by 5 scales method of Likert, total mean scores of time-temperature management in the process of meal production, personal hygiene, equipments and facilities hygiene in university and industry foodservice operations were 3.48, 3.76 and 3.27, respectively. In time-temperature management, the scores for storage, purchasing and receiving, pre-preparation, cooking, assembly and service, and hot or cold holding were 3.77, 3.74, 3.55, 3.54, 3.28, 3.05, respectively, in descending order. The management levels for personal hygiene, equipments and facilities hygiene of foodservices had biger serving scale(over 901) were significantly higher than those of lower scaled foodservices(below 900). The scores of foodservices managed by higher aged dietitian(over 31 years) were significantly higher than those of foodservices conducted by lower aged group(below 25 years) in the management procedures of time-temperature, personal hygiene, equipments and facilities hygiene(p$lt;0.05). The dietitian group had the regular sanitary education showed significantly higher scores than irregularly educated group in the management of time-temperature and personal hygiene. The schedule table for clean and sanitation was used in fifty foodservices. Those foodservices revealed significantly higher ratings than the group without the schedule table in the management procedure for equipments and facilities hygiene(p$lt;0.01). The sanitation management level of fifty nine foodservices used daily sanitation ckecklist showed higher score on personnel hygiene, equipments and facilities hygiene than those of unused foodservices group(p$lt;0.05).
