Korea Electric Power Corporation (KEPCO) is in charge of the operation and the maintenance for transmission lines and substations in Korean power system which is under the deregulation power market. KEPCO has a main constrain of transmission line toward SEOUL area which is a capital of KOREA because SEOIJL is a huge load of Korean power system. The Korea Electric Power Research Institute (KEPRI)), a division of KEPCO was tasked to study the ATC enhancement of transmission line toward SEOUL using a new line or/and FACTS. This paper summarizes the results of those studies, enhancing the ATC and evaluating the economics.

The majority of small/medium sized shipbuilders in Korea is poor in capital and then, should be restructured as an efficient production system with low investment. Due to considering this situation, the cooperative work system is proposed, in this study, as more effective production system for small/medium sized shipbuilder The cooperative work system Is the production system that many small/medium sized shipbuilders in a group jointly share the common facilities except minimum equipments and have managerial cooperation such as joint purchase of raw materials. The efficiency of cooperative work system is proved from economic and technical point of view with the case study of FRP shipbuilders of Sapjin industrial complex located at Mokpo area.

The government encourages adoption of Rahmen structure design to ensure efficient management of national resources. However, in comparison with bearing-wall structure, Rahmen structure requires higher unit construction cost and present challenges in terms of securing adequate floor area ratio and floor height. That is why project clients have been disinterested in adoption of Rahmen structure design. Therefore, we have attempted to find factors having influence on decline of project viability for Rahmen structure. This study will be utilized as a basic reference study for promotion of Green Frame design which is a composite PC structure already developed.

This study investigated the manner in which extraversion, openness to experience and creativity related to school adjustment and explored the mediating role of creativity in extraversion-school adjustment and openness to experience-school adjustment relationships. The participants of this study were 258 undergraduate students from around the capital city and Pusan Greater Metropolitan area. The results revealed that extraversion related positively to openness to experience, creativity and school adjustment. Openness to experience related positively to creativity and school adjustment and creativity related positively to school adjustment. Furthermore, creativity was found to mediate the effects of openness to experience on school adjustment. The influence of openness to experience on school adjustment occurred indirectly through the facilitation of creativity. The importance of extraversion, openness to experience and creativity to predict undergraduate student's school adjustment is also discussed.

The objective of the study is to investigate factors affecting consumers' purchase intention toward imported organic agricultural products. To accomplish the goal of the study a consumer survey was administered for randomly selected households residing in capital area. Results show that the more consumers trust a safety of domestic products and a certification system, the less they purchase the imported products. In addition, it is demonstrated that educated consumers are relatively less reluctant to imported organic agricultural products. Finally, an improvement of domestic certification system, decrease of price of environmentally friendly agricultural products, and aggressive promotion are required to enhance the competitiveness of the domestic environmentally friendly agricultural products.

At present, the manufacturing industry is in a process of great change of circumstances like meeting demands to involve a great variety of types and shorter product life and thus more flexible manufacturing. These changes cause the larger number of different tools and frequent tool changes, which lead to the considerable losses in productive time and the high amount of capital tied up in the tool area. In our country, for the most part, the individual tool are still being presetted according to a data sheet and the measured values are entered, output in a list manually or via punched tapes. This usually takes a considerable amount time and lead to a high error rate. This paper describes a computer controlled tool data management system combined with the bar code tool identification labeled on cutting tools.

At present, the manufacturing industry is in a process of a great change. There is a demand for a variety of types and shorter product life. The change increases the number of different tools and frequencies of tool changes. For the most part, the tools are presetted and offset values are entered manually or via punched tapes to NC machines. Thus a large amount of capital is tied up in the tool area and considerable productive time is lost. Consequently, there is a need for improvement in tool management. This paper describes a computer controlled tool data management system which include: 1) tool identification with bar code. 2) computer aided management and updating of tool data. 3) tool data communication with tool presetter, CNC, etc.

The purpose of this study was to investigate the middle-aged housewive's background characteristics influencing on the preference of elderly housing, depending on four aging-situations. The characteristics of the elderly housing dealt in thes study were geographical location. specially planned feature for the elderly, house type, the size of housing, housemate, the distance from the living quarter of their children, and whether they want to live in the rental house. The subject were 526 middle-aged housewives from middle-income householde living in the capital area. Questionnaires were sent through mail to the householde which tesponded positively on the information brochure about this study sent before. The characteristics of the elderly housing which perferred to was influenced by their age and socio-economic status, such as schooling, job, income, and the size of housing. This result suggests that it must be considered to develop various types of the elderly housing depending on socio-economic status.

The fossil fuel has been used as the main resource of national development. Through this process, many environmental problems have happened. For example, we depend 97% energy on import for national spending and the exhaustion of the fossil fuel is at an important issue nowadays. So more people are interested in renewable energy which is more environmental and never be gone. However, the supply doesn't go on smoothly because of some problems such as capital condition, the limitation of geographical features and low technology, etc. In conclusion I'd like to check some policies and support systems about renewable energy first, and then to find problems for adapting other area through the comparison in this thesis.

A power grid is one of the most complex networks and is critical infrastructure for society. To understand the characteristics of a power grid, complex network analysis has been used from the early 2000s mainly for US and European power grids. However, since the power grids of different countries might have different structures, the Korean power grid needs to be examined through complex network analysis. This paper performs the analysis for the Korean power grid, especially for high-voltage transmission networks. In addition, statistical and small-world characteristics for the Korean power grid are analyzed. Generally, the Korean power grid has similar characteristics to other power grids, but some characteristics differ because the Korean power grid is concentrated in the capital area.
