This study aims to propose a hypothetical urban neighborhood, HanGyo-dong, which is a model for understanding the relationship between the neighborhood change and educational facilities. Three issue layers of the model derived from preceding case studies are: establishment, relocation and redevelopment of educational facilities; formation and redevelopment of adjacent residential areas; and growth of neighborhood commercial cores. The neighborhood changes observed through HanGyo-dong include (1) the formation of educational base and commercial activities along the stream, (2) the growth of student and intellectual community and the installment of public transportation nodes, and (3) the relocation of schools and hospitals followed by a series of redevelopments of single family house into multi-family housing of low-rise residence and high rise apartment complex. The findings call for the collaborative practice of educational administration and neighborhood planning regarding how educational facilities, which were the tool for urban expansion policy, will contribute to the development of the neighborhood's identity as a localized hub.

This paper describes internal flow of a fuel cell's blower, which is mainly used for detached house and apartment. Test blower is operated by a diaphragm, which has suction and discharge port on the top of the blower. For analyzing the internal flow of the blower, three-dimensional Navier-Stokes analysis is introduced in the present study. Hybrid grid system consisted of hexa hedral, tetra hedral and prism mesh is adopted to describe the complex geometry of the diaphragm blower. Throughout the numerical simulation, it is found that the present numerical modeling for analyzing the internal flow of the test blower is suitable for understanding the unsteady nature inside the cavity of the diaphragm. Detailed unsteady flow is analyzed using the results obtained by numerical simulation.

This paper focussed to find out the consumer appraisement and purchase consciousness on organically grown products since public pay more and more attention on organic food and market for organic products has been grown very rapidly. It is intended to deliver the necessary information at first time in Korea to the policy maker for environmentally sound agriculture, establishment for marketing strategy and consumer movement related with it. 66.2% of investigated consumer ever purchased the organic products, and they are inhabitant in apartment complex, belongs to high income group and eldly people, and used to buy frequently at 45.8%. For the reason why they choose the organic products ; 84.7% for health and safe, 48.6% for taste. But the reason why they not choose the organic products ; 56.7% for unconvenient to shop an organic food, 51.4% for expensiveness. On the purchasing the consumer mainly rely upon the certification label(67%), the marketing place(29.6%) and information and recommendation of shopkeeper(23.6%). Korean consumers intend to buy an organic products if variable products and crops are offered in the market and offered at reduced price. The group purchased intensively the organic goods appraise for an organic products positively, and group who do not express any careless intend never to purchase an organically grown products because of its high price. Consumer indicated the support policy and action program by government(69.2%), research & development on organic agriculture and its extension activity(48.8%) are necessary to stimulate an organic agriculture in Korea.

This paper is about the Extra-High voltage distribution system in the customer's area. The power loss in the distribution system in the customer's area is disregarded and rarely managed so far. But, economically, this loss is not small quality to ignore. So, in this paper, we calculate the power loss of the Extra-High voltage distribution system in the customer's area by changing the locations of power transformer and other power facilities to decrease power loss in decreased secondary line length. And we also show the payback time of the proposed Extra-High voltage distribution system in the customer's area by simplified calculations.

A simulation program is developed for analysing thermal networking process between the District heating and the CES(Community Energy Supply) systems. The effects of thermal networking on the District heating facilities previously being operated are implemented using mathematical correlations in terms of the fuel consumption and energy load such as heating and electricity. The operational characteristics according to the prime movers is modeled based on the materials of efficiency as a function of operational load. The unit energy load model is also developed extensively for several building types such as apartment complex, hotel, hospital, buildings for business and commercial use respectively. The specific features of the newly developed program in simulation of thermal networking process in district heating is described in terms of the reliability and the easiness for operating it etc.

The purpose of this study is to find out understand the resident's subjective responses to physical indoor environment. The questionnaire survey was carried out to measure form Jan. 8th to Feb. 2th in 1996, the typical external climate of winter in Korea. The subjects were four hundred and eleven housewives, living in apartments of RC structure I Ilsan apartment complex. As the result, residents usual ventilate once or twice a day by opening outward windows for about ten minutes. Unpleasant smell producted by cooking and wet garbage made most of them negatively respond to kitchen's air quality. regression analysis of relativeness between sense of air freshness smell, dust and comfort revealed that sense of comfort was the most highly related with the extent of bad smell. Housing factors such as size of apartments and ventilating, smoking and gas usage had significant effects on indoor air quality and the subjective responses in winter. Therefore it is especially important to consider air pollution problem from the beginning stage when planning small apartments. It is required that the government of environment has to emphasize the importance of ventilation to residents, and makes an effort to establish the design criteria on indoor air quality in house.

Eco-efficiency considers both environmental impacts and economic values. It is a useful tool for communicating with stakeholders for business decision making. This study evaluated the eco-efficiency factor (EEF) for the energy network of a dyeing company that supplies surplus heat to a neighboring apartment during the night. This symbiosis network is one of the eco-industrial park (EIP) projects in Korea and aims to benefit local residents and the industrial complex by utilizing surplus heat. In this study, two categories were annualized. The first quantified environmental burden based on $CO_2$ emissions and quantified product value in terms of steam sales. The second used a variety of environmental factors, such as fossil fuel, water and waste, to quantify environmental burden and used steam sales to quantify value. The EEF of the symbiosis network was 1.6, using the global warming impact, and determined using the multiple variable, was 1.33. This study shows that the EEF depends on variable details of environmental burden but the values of this project were very high contrast to other business or EIP project.
