Urban centers have been recognized as problem regions so far. However, urban centers of metropolises take a new aspect in recent years as much as the negative influence of gentrification becomes a social issue. This paper analyzes the declining trend of urban centers in six metropolises - Seoul, Busan, Daegu, Incheon, Gwangju and Daejun from 1995 to 2010. As results of analysis, it is identified that the urban centers' shrinkage got moderated recently in the metropolises, even though their resurgence is not evident. Especially it is difficult to say longer that Jongro-Gu and Jung-Gu of Seoul are declining urban centers. Easing shrinkage is most outstanding in Jung-Gu, Daegu among local metropolises. Nevertheless, a serious obstacle such as high price of housing is in the process of obvious resurgence of urban center differently from the United States, Europe and Japan.

많은 지역에서 구도심 개발이 지역정체성을 훼손하고 거주민의 소외라는 부작용에 직면하고 있는 가운데 가장 모범적인 도심개발사례 중 하나로 손꼽히는 부산 감천문화마을을 통해 지역의 문화와 역사가 어우러진 대표적인 명소로 자리 잡게 된 과정을 소개한다. 지역개발은 다양한 측면의 가치 창출을 동반하는 종합적인 기능과 더불어 관광수익의 창출이라는 경제적 가치를 추구한다. 감천문화마을은 구도심과 신도심간 양극화를 해소하고 지역이미지를 제고하는 차원에서 의미있는 도심재생사례가 될 것이다.

This study examines and analyzes residential environment and factors with partial region of Chungjang-dong, Dong-gu, Gwangju based on land register and questionnaire. Consequently, most of residents are in their forties or over and working at downtown or place near it. It is found that rate of their own house is high and they live in the current house over 10 years. Residential factors at downtown area include its convenience, distance to workplace, convenient transportation and easy use of cultural and commercial facilities, but their consciousness of residence shows a low satisfaction with children education, air pollution, noise, parking facilities, green zone for making community, resting place, sunshine, view and privacy.

This research was investigated to examine the status of goundwater contamination in Chung-Nam area over 2 years from 1996 May to 1998 May. The results show that the overall detection rates of VOCs (volatile organic compounds) by region were as followed: industrial region > agricultural & industrial complex region > gas station region > around industrial region > downtown region, and excess rates of those were as followed: industrial region > gas station region > agricultural & industrial region > around industrial region > downtown region. Benzene and TCE of VOCs examined in Chon-An industrial region exceeded drinking water standard. At the agricultural & industrial complex region, the observed mean concentration of TCE was 3.107 mg/L and TCE was also detected at 48.152 mg/L which is 100 times higher than drinking water standard, and other VOCs were also observed at higher concentrations as well. Based on our studies, It is concluded that appropriate remedial action should be performed to protect further groundwater contamination and to restore groundwater quality in Chung-Nam area.

This paper aims to investigate changes in the characteristics of urban spatial structure in Korea by regional groups and city size between 2000 and 2010. The characteristics of urban spatial structure is analyzed by Clark's population gradient curve in this paper. Therefore key parameters in population gradient function, such as population density gradients and population density in CBD represent the characteristics of urban spatial structure. The result shows that most of cities in Korea have experienced suburbanization rather than concentration, but small-size cities have experienced concentration during the period.

The subjects were fifteen dong at downtown of Busan. LQ index and cluster analysis were used to research space functions of downtown in both years, that is to say, 2000 and 2005. At the analysis of LQ index in 2000, the secondary industries were specialized at traditional markets as well as large-scaled commercial districts, while the tertiary industries were done at financial business districts. LQ index in 2005 did not make change mostly comparing with the one in 2000: But, main businesses at downtown that belonged to the tertiary industries rapidly dwindled at old downtown to make appearance at Seomyeon of new downtown. Main businesses at old downtown in the past moved to new downtown to dwindle main functions at old downtown. The cluster analysis was done by using LQ index to classify into three clusters. The first cluster was old downtown that functions of downtown dwindle, and the second cluster was residence area, and the third cluster was the area where space function at downtown was very much active. The findings were as follow: Firstly, various kinds of urban regeneration plans should be made to control dwindling of old downtown and to establish comprehensive and systematic plans on new downtown. Secondly, downtown space functions could be placed depending upon specialization of each industry so that industries being suitable to the area should be introduced to construct development base.

지난 2010년 9월 21일 서울을 비롯한 우리나라 중부지역에 급습한 집중호우로 인하여 저지대 및 지하 공간 등에 상당한 홍수피해가 발생하였다. 이는 도심지역의 기존 수방대책의 한계점을 절실히 드러낸 호우사상으로 향후 극한 강우에 대비한 대응책 마련이 시급할 것으로 판단되며, 이러한 도심지역의 집중호우에 의한 홍수피해를 미연에 방지하기 위한 구조적 대책으로 저류조 설치를 고려해 볼 수 있다. 본 연구에서는 도심지역에 시공이 간편하며 유지관리가 편하고 공사비가 저렴한 PN(Plastic Nodular) 빗물저류조를 설치하였을 경우 타 공법에 비하여 장점으로 부각될 수 있는 효과와 집중호우시 우수저감 효과를 분석하였다. 분석결과 PN 빗물저류조 설치시 상부 토지이용계획이 가능하며 사업비의 절감과 악취, 해충발생에 따른 민원 및 안전사고 등의 문제점이 해소 되는 것으로 분석되었다. 또한 호우시에는 방재 기능과 갈수기에는 부족수량을 대체 이용할 수 있으며 평상시 저류조 상부는 근린공원과 체육시설 및 별도의 부족한 차량의 주차장 공간 등으로 이용 가능효과가 있는 것으로 분석되었다.

This study defines three types of public parking for commercial business, cultural tours, sales and market areas. We compared the Santa Barbara parking system with Korean examples for use in urban revitalization with a proper planning strategy based on district-specific public parking. The results are as follows: 1. The layout and location of public parking entrances need to consider the urban grid and linkages. 2. Public parking should place emphasis on respecting a district's character and user convenience. 3. The success of public parking extends to revitalization of pedestrian paths at target areas.

Urban streams are degrading functional role due to development and pollution. This study chose the representative stream of Do-rim and identified flora and fauna. The ecological survey aimed at identifying indicator of urban streams for measuring urban healthiness and we discussed the possibility of wetland conservation area. From the beginning of Dorim stream to An-yang mixture we were successfully identified 113 species of plants, 9 of mammals, 23 of birds, 4 of amphibians, 2 of reptiles and 2 of fish species. Terrestrial insects were 71 species. The wetland vegetation is quite various and we suggested 4 different vegetation zones (aquatic vegetation zone, emergent zone, riparian-meadow zone, riparian-woodland zone) depending on distance from the flowing water stream and vegetation characteristics for urban stream management.
