The very problem we are to touch in this study is that our own types of urban housing complex are isolated from the existing residential environment. The closed and self-completing structures of past urban housing complexes didn't develop the communal spirit and it has increased anti-city trends. With all that, this study intends to provide some materials to reform our urban housing environment through analyzing former European examples on the basis of the development of our own urban housing types which will correspond with existing urban structure and urban tissue.

According to the complexity and the pluralism of the modern cities, they are changing themselves into the multinoded and social - classless urban environments. The sudden drift of population to the cities is giving rise to the serious environmental problems, and the rapid increase of recreational needs among the citizen is changing the urban society into a leisure - oriented one. In order to coping with the abrupt change in the social and natural urban environments, the various fields of urban society should be co - ordinated. The study uses the green - city concept to get solves the incongruity of urban structure in Chonju City. The existing open space maps were drawn up by the various techniques such as the analysis of the topographic maps and collected data, the interpretation of the aero-photographs and the reconnaissance of site. The authors suggested the existing condition, and the problems and potentials of open space elements in Chonju City through the analysis of the existing condition maps. After synthesizing the contents of analysis, the 7u(hors established an exclusive open space system for Chonju City.

It is required to response to the demand for new space due to high density of population and buildings in urban area. In particular, in case of big cities such as Seoul where the lack of new construction site due to the depletion of available space, existing buildings must be demolished for new construction. Utilization of urban underground space can be an alternative to solve for urban space problems. There are applications of underpinning methods using micropiles for existing buildings. Sometimes, the difficulties come from the compact space available for new foundation underneath the existing ones. In this paper, a novel underpinning method is introduced which can solve the space restriction problems underneath existing columns.

Urban parks and open spaces provide the community residents with the most easily accessible source for outdoor recreation, contributing also to the improvement of quality of natural environment in urban area. The demands of urban residents' for more and better green area are ever-increasing. However, the level of most urban open spaces which are easily accessible for residents are not satisfactory to meet the residents' demand in availability and in quality as well. Most existing urban open spaces are simply built of green areas only or have been developed in almost identical design with little consideration for individual uniqueness of the site. When developing neighbourhood parks in urban housing complexes, for example, little consideration is being given to topographical conditions, interrelation with the adjacent green area, or viability of the urban ecosystem. In many cases, urban park development projects are being done with serious negligence of natural properties of the site, by even destroying existing healthy woodlands. for instance. The objectives of this study are; -To survey on the domestic and the overseas cases of regulatory systems, development status and planning methods for urban open space. -To identify underlying issues of residental park developments in urban housing projects and establish appropriate improvement measures thereof, by studing and analyzing current-use data of developed urban parks and management status thereof. -To establish improved standards for urban open space planning, by integrating above surveys and studies, and recommendation for revision of related legislation is also presented to implement these standards.

The existing track structure for urban Maglev system is designed for the Maglev vehicles of HSST in Japan and UTM in Korea. The tracks hvaing cross beams for supporting rails are located on bridge girders and have several draw backs. Linimo in Nagoya, Japan, the first commercial urban Maglev line, has separated tracks from a bridge to overcome the previous track structure. However, the Linimo just put the existing track on bridge deck. This study suggests a improved track structure for urban Maglev system and compares the behavior of the new and existing track through static structural analyses. In the improved track, the power collector of a Maglew vehicle is installed parallel to the bridge deck surface, and, thus, the bottom width of the track structure is not limited by the vehicle's width. Therefore, the live load is distributed more effectively by the wide bottom of the track. Also, steel plates instead of steel cross beams are used to support rails, and, thus, the rail's deflection is improved.

낙후된 도시 주거지 재생의 방안에 대한 논의와 연구가 활발하게 진행되고 있다. 그러나 도시농업을 단순히 주민참여의 수단이나 일차산업으로서의 가치에 대한 논의가 부분적으로 이루어지고 있는 실정이다. 기존의 공간자본가치 극대화의 수단으로 전락한 도시개발의 새로운 극복방안으로 장소자본 가치를 높일 수 있는 대안이 모색되어야 할 시점이다. 따라서 본 연구는 창조적 산업융합개념을 적용한 도시농업의 장소적 가치를 논의함으로써 지속가능한 도시재생의 단초를 이론적 바탕을 제공하는 것이 목적이다. 이를 위하여 기존의 도시개발 방식의 문제점, 산업융합과 도시농업의 의미, 그리고 산업융합형 도시농업의 장소가치에 대한 이론적 연구를 통해 도시재생의 새로운 패러다임을 제시하고 있다.

Existing buildings in urban parks are a kind of thing that has been settled and occupied on the site of an unexecuted park. The aim of this study is to identify nature by analyzing the causality and path-dependency through the transformation of the relevant system. The scope of the study was set up as a system for the occupancy of urban parks from 1934 when the building restriction system was established to 2000 when purchase claim (매수청구권) was introduced. The method of study was to get correlation by harmonizing the external and internal mechanisms affecting the relevant institution. The related system showed a modest change in the fourth stage, polymerizing the initial system. In the 1950s and 1960s, the existing buildings in urban parks were 'disguised' by government and the 'regulation' principle was applied since 1967. In the 1980s, the principle of 'protection' and 'support' for parks was added, but in the 1990s, the principle of regulation began to be lifted as the long-term unexecuted urban park (장기미집행 도시공원) problem continued for more than 60 years. Although the public concept of land ownership (토지공개념) has worked strongly for nearly 30 years since 1960, the system has developed into a form of deregulation since 1980. The nature of the relevant institution is first, dependent on the higher-level system and vertical. Second, it implies a conflict of restrictions and acceptance. Third, it is a temporary measure of the park problem. Therefore, the relevant system has long been enhancing the encroachment requirements on urban parks, so fundamental readjustment is needed in the future.

PURPOSES : This paper aims to improve the evaluation method of the Level of Service(LOS) for urban streets presented by the current Korean Highway Capacity Manual(KHCM) and suggest its utilization plan as a part of the methods to evaluate the sustainability of a transportation policy. METHODS : This paper carried out a research in 3 steps to develop a new evaluation method. First of all, this paper reviewed the previous studies related to the LOS of urban streets and the socially requested items for a sustainable transportation system. Then this paper derived an index and weight through expert questions to select an evaluation index. Lastly, this paper compared the results according to the existing evaluation methods with the new evaluation methods through case studies. This paper used an Analytic Hierarchy Process(AHP) for importance analysis and weight selection between new evaluation items and indices, and applied a Grey System Theory(GST) for a synthetic and integrated evaluation between the selected evaluation indices. RESULTS : As a result of evaluating the LOS according to the existing evaluation methods and the integrated evaluation methods using a GST through case studies, it was analyzed that new methods' results are less than or equal to the existing evaluation methods; and as a result of applying a weight between evaluation indices according to AHP, it was noticed that the total score seems to rise more when the LOS in the existing evaluation is calculated lower. It was analyzed that the LOS calculated by reflecting the newly established evaluation items and the importance between indices in this study has difference from the LOS of the existing urban streets. CONCLUSIONS : It is expected that this evaluation method can diagnose the current conditions when establishing a future sustainable traffic system and can be used for the measurement of the sustainability effects of the improvement plans and so on.
