Although Changdong Sanggye area has been developed during 1980s as a new city for the supply of low-income housing, currently it was degraded to a bed town located outside Seoul. However, Changdong Sanggye area is designated as the center of a metropolitan area in '2030 Seoul City Basic Plan' due to a variety of potential factors such as a traffic center for linking metropolitan areas, location of 15 universities, and neighboring natural environment like Jungnang stream and Buckhan mountain. The purpose of urban regeneration plan is to create a new CBD of Changdong Sanggye which is the center of vocational and cultural lives of 3.2 million people in the northeastern metropolitan area. To achieve the purpose, 12 unit projects and 24 sub-unit projects are set up based on the three major goals and core strategies. An enterprise project team of northeastern area was newly founded and then a dedicated organization was established by the Seoul government in 2015 in order to integrate separated urban regeneration related functions. In the Seoul government an administrative council and a project promotion council are operated for consultation and coordination between the administrative divisions and government projects for urban regeneration. Through the success in Changdong Sanggye regeneration project, they are expected to have economic effects such as job creation and increase in tax revenue and to re-vitalize the area as a new economic center in northeastern Seoul having amenities and cultural facilities and waterfront parks.

The Korean government strengthened the environmental polices to manage and enhance Metropolitan Area air quality, and also has enforced "Special Act on Seoul Metropolitan Air Quality Improvement (SASMAQI)" issued in Dec. 2004. Recently government expanded the Seoul Metropolitan Air Quality Management District (SMAQMD) to the outskirts satellite cities of Seoul area through the "Revised Law Draft of SASMAQI". The SMAQMD has been alloted the allowable emission loads to the local governments on the basis of the carrying $PM_{10}$ capacity. However, in order to establish the effective air quality control strategy for $PM_{10}$, it is necessary to understand the corresponding sources which have a potential to directly impact ambient $PM_{10}$ concentration. To deal with the situations, many receptor methodologies have been developed to identify the origins of pollutants and to determine the contributions of sources of interests. The objective of this study was to extensively identify $PM_{10}$ sources and to estimate their contributions at the metropolitan area. $PM_{10}$ samples were simultaneously collected at the 3 semi-industrialized local cities in the Seoul metropolitan area such as Hwasung-si, Paju-si, and Icheon-si sites from April 15 to May 31, 2007. The samples collected on the teflon membrane filter by one $PM_{10}$ cyclone sampler were analyzed for trace metals and soluble ions and samples on the quartz fiber filter by another sampler were analyzed for OC and EC. Source apportionment study was then performed by using a positive matrix factorization (PMF) receptor model. A total of 6 sources were identified and their contributions were estimated in each monitoring site. Contribution results on Hwasung, Paju, and Icheon sites were as follows: 33%, 27%, and 27% from soil source, 26%, 26%, and 21% from secondary aerosol source, 11%, 11%, and 12% from biomass burning, 12%, 6%, and 5% from sea salt, 7%, 15%, and 19% from industrial related source, and finally 11%, 15%, and 16% from mobile and oil complex source, respectively. This study provides information on the major sources affecting air quality in the receptor sites and thus it will help to manage the ambient air quality in the metropolitan area by establishing reasonable control strategies, especially for the anthropogenic emission sources.

The purpose of this study was to investigate the analytical model of the implicit price according to objective and subjective characteristics of housing. The hedonic price regression was used for estimating the implicit price. The subjectives of this study were 1,143 dwellers who live in Seoul metropolitan area. Taejeon, and Jeonju. Satistical analyses were conducted using frequencies, percentiles, mean, and multiple regression. The major findings were as follows: 1. There was a significant difference in the implict price of the apartment between owners and renters. 2. There was a sginificant difference in the implicit price of the apartment among Seoul metropolitan area, Taejeon, and Jeonju. 3. Using a stepwise multiple regression method, the order of variables as they were entered in the model were different between tenure types (owner/renter), and regions(Seoul metroplitan area/Taejeon/Jeonju). 4. The linear model was the most appropriate noe which explained the housing price. 5. Subjective characteristics of housing in Taejeon and Jeonju had an effect on the housing price more than those in Seoul metropolitan area.

The purpose of this paper is estimating environmental carving capacity of Seoul Metropolitan Area for a sustainable city management using system dynamics model. A sustainable development requires a society to define sustainability constraints or environmental limits, environmental carving capacity. Environmental carving capacity can be defined as the level of human activity which a region can sustain at an acceptable quality of life level. This concept of environmental carving capacity has several important application to sustainable city planning and management. If the limitation of a human activity can be supported by a scientific data on carving capacity, the resulting decision and actions could more easily win public support for a sustainable development. However, one of the key issues is how to operationalize the carving capacity. In this paper, the environmental carving capacity was operationalized as a maximum number of industry structure, population, and housing that can sustain certain level of environmental quality of Seoul Metropolitan Area. The model developed in this paper consisted off sectors: population, housing, industry, land, and environmental sector. The model limits its main focus on the NO$_2$level of ambient air of Seoul. Carving capacity Seoul Metropolitan Area was estimated by figuring out the maximum number of population, industry structure, housing at an equilibrium point that sustain a desirable NO$_2$level. Based on the model estimation, several policy implications for a sustainable city management was discussed.

This study aims to analyze the relations among greenbelt, urban land surface temperature empirically in order to assess the environmental effects of the greenbelt in the Seoul metropolitan area, objectively. For this purpose, this study conducts an empirical analysis of impacts of greenbelt on urban land surface temperature using a multiple-regression model. The main data employed in the analysis include real-time air pollution data, Landsat 8-OLI Landsat imagery data, KLIS data and Jip-gye-gu data. The major findings are summarized as follows. NDVI has a negative (-) correlation with the land surface temperature, and the urban temperature is high in areas with poor vegetation. The land surface temperature is low in residential or commercial areas, while the temperature is high in industrial areas. The temperature is low in green fields, open spaces, and river areas. it is found that the urban land surface temperature is low in the greenbelt zone. In the greenbelt zone, there is an effect that reduces the land surface temperature by 1% on average, as compared to that at the center of the Seoul metropolitan area. Especially, the center of the Seoul metropolitan area, in a range from 0.6% to 1.9% of the average temperature, the temperature gets lower up to approximately 3km from the greenbelt boundary.

본 연구는 당해도시와 연담도시권 내 도시들의 특성과 단위면적(m²)당 아파트 거래가격 간의 상관성을 확인하는 목적을 가지고 수행되었다. 구체적으로 당해 도시 및 연담도시권 내 도시들이 인구 특성. 산업 특성, 도시계획사업 및 개발사업 특성, 입지적 특성이 아파트 m²당 매매가격 형성의 원인으로 작용하는지, 당해도시와 연담도시 간에 차별적인 특성을 보이는지 또한 수도권과 비수도권 간에 차별적인 특성을 보이는지를 상관분석, 다중회귀분석을 통해 파악하고자 하였다. 인구특성 부문에서는 모두 상관성이 있는 것으로 나타났다. 산업부문과 도시계획사업 및 개발사업 특성 부문은 당해도시에서는 유의하지 않게 나오지만, 연담도시권으로 분석하여 볼 때, 유의하게 나타나는 것으로 된다. 수도권과 비수도권으로 분류하여 분석하여 볼 때, 인구 부문은 수도권 및 비수도권 모두 유의하게 나타나며, 입지적 부문에서는 강남구와의 거리만이 유의하게 나타난다. 이는 지금 수도권으로 인구가 집중되기 때문에 아파트 m²당 매매가격도 수도권 집중으로 높은 가격대를 형성하는 것으로 이와 같은 결과가 나타나는 것으로 판단된다. 본 연구는 아파트 m²당 매매가격에 영향을 미치는 요인을 분석할 때, 당해도시 뿐 아니라 인접 지역들의 특성을 같이 분석하여야 한다는 결과를 보여주며, 또한 부동산 정책을 실시할 때에도 당해도시 뿐 아니라 연담도시권으로 설정하여 주택시장 모니터링이 함께 이루어질 필요가 있다는 점을 시사한다.

본 논문에서는 서울대도시권 통근자들의 통근시간에 영향을 미치는 요소들에 대해 살펴보았다. 도심에 소재한 직장으로 출퇴근하는 주민들의 이동시간을 결정짓는 요인을 판별하기 위하여, 가구통행실태조사 자료를 이용한 다중회구분석을 실시하였다. 분석 결과에 따르면 통근자들은 주거공간이 규모보다 시간의 가치를 보다 중시하는 것으로 나타나, 최근의 소득계층별 분리 현상은 주택 수요의 증가보다 직장의 지리적 분산 및 교외지역의 쾌적성에 기인한다는 추론을 가능케 한다.
