A local government is not a group under central government, rather it fulfills the function independently as a economic social administrative unit. Belief and role of chief of regional government, and citizen's understanding and interest regarding importance of an election pledge are getting higher. Thus, this study researches election pledges which can be a main variable of urban plan. Especially, the study attempts to analyze impacts of election pledge on urban spatial structure and regional economic structure. When relationship between election pledge and Use Zoninig change were analyzed, the result showed that development related entire use Use Zoninig changes were related with election pledge. When it was subdivided according to each use area, relationship of use area change among election pledge and urban spatial structure found to have relatively high in resident area. In addition, relationship between population factor and election pledge was high. This can be judged as election pledge and urban spatial structure change have relationship. Particularly, sectors related with residents are expected to have high correlation. As a result, pledges regarding general welfare administrative part were a few at areas with many pledges regarding regional economic development. So, it can be classified as regional economic development oriented pledge suggesting area and welfare administrative oriented suggesting area. Through realization of these pledges, it might be able to affect urban spatial structure changes.

1) 연구의 배경와 목적 정보통신기술의 비약적 발전은 공간이동에 있어서 '거리' 개념의 근본적인 변화를 가져오고 있다. 흔히 '시간에 의한 공간소멸' 또는 '시공간 압축'이라고 표현되는 그와 같은 변화는 일상적 생활공간에서뿐만 아니라 전지구적 범위에 이르기까지 장소와 장소, 지역과 지역 간에 발생하는 정보의 흐름을 실시간(real time)으로 연결한다. 그러나 정보통신기술의 발달이 장소와 장소, 지역과 지역 간에 발생하는 모든 통행을 대체하지는 못한다. (중략)

As large-scale housing sites are being developed rapidly in Sejong City, which was launched in 2012 for resolving the adverse effects of overconcentration in the capital area, promoting balanced development of the country, and reinforcing national competitiveness, changes in spatial structure are expected in the surrounding areas. For setting the directions of urban planning, it is essential to understand changes in spatial structure. This study purposed to measure changes in the spatial structure of neighboring areas resulting from the construction of Sejong City by approaching from the aspect of spatial interaction. In the analysis, we calculated population potential for future spatial interaction using the accessibility model, and interpreted quantitatively and qualitatively the outcomes of spatial interaction among neighboring areas before and after the construction of Sejong City using population potential as an indicator. According to the results of the analysis, the impact range of the population potential of the subject areas had been shrinking continuously since 1995, and in 2013 population potential dispersed as the population concentrated on and around Cheonan City. Although Sejong City, as a new area of population potential, was not found to play the role of a pivotal point for the surrounding areas, it is probably because the analysis was made just after people began to move to Sejong City. Accordingly, along with the effort of Sejong City to reach the planned population, it is necessary to keep monitoring changes in related factors and changes in the spatial structure of the surrounding cities resulting from the growth of population.

최근 도시화가 급격히 진행되면서 도심 공간의 효율적인 이용을 위하여 지하공간의 개발이 새로운 대안으로 주목 받고 있다. 지하공간은 일반적으로 건축 구조상 자연채광의 유입이 불가능한 구조로서 지하 거주자의 심리적, 환경적 문제를 초래하므로 이의 활성화를 위해서는 공간의 질적 제고가 선행되어야 한다. 빛과 조명은 공간의 질을 결정하는 중요한 요소로서 거주자를 위해 건강하고 편안한 환경을 제공하기 위해서는 거주자의 생체리듬과 부합하는 자연광과 유사한 광 환경(색온도, 조도) 서비스를 제공해야 한다. 본 논문은 지하공간을 대상으로 인공조명의 광 환경을 시간의 흐름에 따라 변화하는 자연의 빛과 유사하게 서비스하기 위한 LED제어시스템을 개발한다.

The purpose of this study is to produce time-distance cartograms based on the various Korean transportation networks, and to analyze the spatial structure of time-distance accessibilities. For the purpose this study attempts to develop continuous area cartogram by utilizing Wolf's algorithm for creating contiguous cartogram in ArcGIS 9. The absolute physical space was transformed to the functional space indexed by time-distances along various transportation networks in Korea. We examined the differences in the time-distance accessibilities among transportation networks. This study makes a comparison between the spatial structure of time-distance accessibility of KTX network with them of existing railroad network, as well as with them of road network. In order to clarify the spatial structures of time-distance accessibilities, we restructured them on the time-distance circular diagrams and performing Multi-Dimensional Scaling analysis. Overall structure of time-distance accessibilities shows similar patterns: The time distances are shrinked a lot along the Seoul-Busan axis, while coastal parts, in particular the eastern part of the county, are shrinked relatively little via all transportation networks. The Road network affects significantly on the accessibilities of cities in Gangwon-do and Gyeonggi-do, while railway network affects on the accessibilities of cities in Jeolla-do and Gyeongsang-do in general. When we compared the time-distance accessibilities based on the 5 largest cities, Seoul appears as the most accessible city from/to all other cities in Korea. We can also find significant changes in the time-distance accessibility between KTX network and existing railroad network. Cities along the KTX network, in particular cities which has KTX stops, improved significantly in time-distance accessibilities.

도시화는 현대사회의 가장 큰 특징이며 도시가 성장하면서 과거의 기능이 변화하고 도시내부의 공간구조가 점차 기능적으로 분화하는 경향이 있다. 그 중 가장 주목할 만한 것 중의 하나는 주거지역의 입지변화와 공간적 확산과정에서 나타나는 주거지 분화현상이다. 도시생태학자 Hoyt은 주거지 이동패턴에 대하여 도시 내의 주거지분포 패턴을 결정짓는 핵심적인 요인으로 최고지대를 지불할 수 있는 부유층의 주거입지 선택에 따라 전체 도시의 계층별 주거분포가 영향을 받게 된다고 주장하였다. 서울은 소규모로 계획된 역사도시에서 인구 1000만의 대도시로 성장하여 오면서 많은 구조적 변화를 경험하여 현재의 공간구조를 이루게 되었다. 현재 전체 서울의 주택지는 동일한 것이 아니고 각종 주위환경에 따른 성격과 특성을 달리하는 요소로 구성되어 있다. 이 특성을 달리하는 주택지들이 모여서 각기 상이한 역할을 수행하고 서로 기능적 관계를 맺으면서 주택지를 형성하고 있다. 선형이론(Hoyt's Sector theory)에 따르면 고급주택지역의 도시 공간구조에 많은 영향을 미치고 있다고 주장하였다. 그럼에도 불구하고 서울의 고급주택지역의 분포와 그 입지 특성에 관한 연구는 미비한 실정이다. 본 연구의 목적은 서울시 고급주택지역의 분포를 형성하는 원인을 규명하는데 있다. 고급주택지의 지역적 분포를 파악하여 그 입지 성향과 특성을 알게 되면 도시의 토지이용계획, 특히 주거지계획에 도움이 될 수 있다.

Land price contains the comprehensive characteristics of urban space, representing the social and economic features of the city. Accordingly, land price can be utilized as an indicator, which can identify the changes of spatial structure and socioeconomic variations caused by urban development. This study attempted to explore the change in land price by the road construction. Methodologically, it adopted Space Syntax, which can interpret urban spatial structure comprehensively, to identify the relationship between the forms of road networks and land price. The analytical results show that the correlation between 'integration index of Space Syntax' with 'officially assessed land price' was the highest, and as integration was higher, 'officially assessed land price' increased. Subsequently, using regression equation, it tried to predict the land price changes of surrounding areas, according to the new road construction in case area. As shown above, the research methods or study results have the advantage of predicting the changes in land price that can attract high concern of residents in an easy way. In addition, it will contribute to establishing relevant polices and smoothing business promotion through the enhancing residents' understanding by suggesting the change in land price in advance before the execution of urban regeneration and development projects.

Statistical regression and/or interpolation models have been used for data analysis and response prediction using the results of the physical experiments and/or computer simulations in structural engineering fields. These models have been employed during the last decade to develop a variety of design methodologies. However, these models only handled responses with respect to space variables such as size and shape of structures and cannot handle time-variant dynamic responses, i.e. response varying with time. In this research, statistical space-time metamodels based on multiple response approach that can handle responses with respect to both space variables and a time variable are proposed. Regression and interpolation models such as the response surface model (RSM) and kriging model were developed for handling time-variant dynamic responses of structural engineering. We evaluate the accuracies of the responses predicted by the two statistical space-time metamodels by comparing them with the responses obtained by the physical experiments and/or computer simulations.

This study investigated the characteristics of spatial expansion/centralization and the spatial structural change of urban. The data used in analysis were urban population, employment, building floor area, and land price. The analysis was performed for the data of 1995, 2000, and 2005 during 10 years after 1995. The method of research was as follows; The movement of mean center and standard distance/standard deviation ellipse was estimated to investigate the urban growth change. The result of Moran's I analysis showed a clustered pattern, not a dispersed pattern, however; the effect was not significant. The town area requires the well-ordered urban planning such as land use. The contours map demonstrates that a monopole structure was generally transformed into a multicentralization structure. The development of mutural connection axis among central street roads was fragile.

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.
