When we construct a road near an apartment complex, we consider a soundproof wall. To make residential places quieter, we may consider a soundproof road tunnel. Such a tunnel, however, would become highly concentrated with soot from vehicles whenever a traffic jam might occur. To create an optimum design, this study utilizes the PHOENICS-VR software. The work considers three cases: (1) no openings (2) openings at 30m intervals, and (3) openings at 60m intervals on the upper side of the tunnel. The study finds that in the second case shows CO concentration distributions were 15% less than those without openings. And the CO concentration distributions of the second and third cases are almost the same. The findings suggest that we should make the soundproof tunnel to reduce construction fees.

In modern society, sense of crisis from environmental destruction caused by rapid industrial development, economic growth and improvement of educational level and medicine made environmental preservation and comfortable residential environment a necessary and sufficient condition. Since government conducted 'green building rating system' from 2002, application of pro-environmental elements has been extended. But the concept of substantial pro-environmental housing remains the stage of complex planning yet and application of system to interior space which has the most direct influence on actual dwellers is very poor.

This study intend to analysis the main issue of deterioration of old housing complex for reproduction and derive the solution. Most of existing reproduction of hosing complex pushed to improve residential environment or expected rise real estate in value. For that reason, there was a limit to improve social problem of urban area behind hosing complex and surrounding area. Because government propel to make brand of city, have parking facilities and rise floor space index rather than established reproduction plan based on the aging problem of housing complex. Therefore, city need to deduct major reproduction issue to improve aging problem and prepare effective counterplan in complex and surround area by reproduction. This study progress through three steps of research. First, arrange problem of aging complex and way of response sustainably. Second, understand the importance by group toward improvement and aging problem that appear aging apartment complex through survey and opinion of expert. Third, comprehend major reproduction issue over this.

This study explores the environmentally innovative and low-impact technology, a zero food waste system (ZFWS) that utilizes food waste and converts it into composts or biofuels and curtails carbon emissions. The ZFWS not just achieves food waste reductions but recycles food waste into fertilizer. Based on a fermentation-extinction technique using bio wood chips, the ZFWS was employed in a field experiment of the system installed in a large-scale apartment complex, and the performance of the system was examined. The on-site ZFWS consisted of three primary parts: 1) a food waste slot into which food waste was injected; 2) a fermentation-extinction reactor where food waste was mixed with bio wood chips made up of complex enzyme and aseptic wood chips; and 3) deodorization equipment in which an ultraviolet and ozone photolysis method was employed. The field experiment showed that food waste injected into the ZFWS was reduced by 94%. Overall microbial activity of the food waste in the fermentation-extinction reactor was measured using adenosine tri-phosphate (ATP), and the degradation rate of organic compounds, referred to as volatile solids, increased with ATP concentration. The by-products generated from ZFWS comply with the national standard for organic fertilizer.

The dust chute was a part of equipment in apartment which have been settled down as new residential style in this country since 1960s. However, the dust chute was destructed by results of social discussion, and it ended up old remains which cannot be found in new towns. Nowadays, chute was substituted a collecting system from extra collecting sites which were prepared near residential area. This phenomenon was caused by the poor separating collection. Since the early part of 1995, the whole vocal operating the volume-base charge system has been placed as the institution capable of recycling and separating collection of residential wastes in this country. People pursue the residential quality which is suitable to the Greenround period. Such a diverse effort corresponding to the social change can be also accomplished in the field of waste collecting transportation. In this paper, the local heating system and waste combustion site and hollow are already applied to the new residential area in the form of housing development. After investigating of the waste collecting transportation method in other countries related to such facilities, this paper represents the feasibility and applicability of pneumatic waste collection system which is used practically in the new housing complex and large facilities in other countries.

The purpose of this study was to investigate the characteristics of leisure behavior and preference for leisure environment of the five-day workweek company employees according to gender for developing leisure facilities in residential community planning. The questionnaire survey was used. The subjects of questionnaire survey were 338 staffs of 7 companies, who were living in apartment complex. The questionnaire consisted of way of life about leisure, leisure necessity, actual condition and need of leisure spaces, and leisure satisfaction. Frequency, percentage, and mean, ${\chi}2-test$, t-test, and factor analysis were used for data analysis. The major results were as follows. 1) In terms of leisure time in weekend, the available leisure time distribution, and leisure cost, there were not difference between men and women. 2) After five-day workweek, the men and women showed to increase their leisure activities and to engage in diverse forms of leisure. Also, they showed an increased desired ratios in participating in each leisure activities. 3) Leisure was necessary to strengthen the unity of family and cultivate the sentiment. 4) Even though current main area for leisure were in their house, men were likely to change them from in the house to around and near their house. And they needed leisure facilities which was closer to their house. 5) The degree of satisfaction of leisure facilities in residential environment was low and there were not difference between men and women. This result implicated to improve and develope leisure space and facilities near the residental environment for promoting leisure behavior of both women and men. In particular it is necessity to create the good atmosphere of leisure facilities for women.

Recently rapid urbanization facilitates development of high-rise building complex including apartment and office building in urban area. Many problems related with high -rise building are reported. Especially, unpleasant strong winds in pedestrian area are frequently encountered around the high-rise building. CFD simulation methods are used to analyze the wind environment of pedestrian level in high-rise building block. However, the results show differences between CFD and measurement. This difference is attributed to improper use of CFD. Conventional CFD simulation for wind environment around high-rise building does not describe the effect of trees, shrubs and plants near ground which affect the wind environment of pedestrian level. Canopy model can be used to reproduce the aerodynamic effects of trees, shrubs and plants near ground. In this paper, CFD simulation methods coupled with the tree canopy model to predict wind environment of pedestrian level in high-rise residential building block were suggested and the validity was analyzed by comparison between measurement and CFD results.

This examination was conducted as follows; 189 copies were coated in total, and demonstratively analyzed by SPSS WIN 15.0 program. The methods used in data for this analysis are as follows; Sensitivity, Reliability, Frequency, Internal consistency, One way ANOVA(Scheffe's examination) Analysis, T-test, etc. The findings of this study are as follows; firstly, it was revealed that respondents who were regular customers of Italian restaurants regarded convenient transportation, property of space, property of pastoral, visibility, and accessibility as importance. This means that Italian restaurant marketers should consider some of factors of location for business with a good view, good parking lot, location at main street, smooth flow of traffic, luxury, atmosphere of freedom, clean area around restaurants, elegant interior of the building, comfortable, luxurious, and deluxe atmosphere, and so on. Secondly, it was revealed that respondents who were regular customers of buffet restaurant either considered the same factors as the Italian restaurants above or regarded those factors less important. This suggests that restaurants should be located on main streets, on trunk roads, and in large-scale residential districts of apartment complex. Thirdly, it was revealed that respondents who were regular customers of traditional restaurants did not consider the locational factors above. This shows that traditional restaurants should be located in nearby customers' houses or their working places, and that marketers should consider focusing on their restaurants' homelike atmosphere, cleanliness, food flavors, and so on.

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.
