  • The purpose of this article is to examine land use change in the fringe area of a metropolitan city through multi-temporal data analysis. Change detection has been regarded as one of the most important applications for utilization of remotely sensed imageries. Conventionally, two images were used for change detection, and Arithmetic calculators were generally used on the process. Meanwhile, multi-temporal change detection for a large number of images has been carried out. In this paper, a digital land-use map and three Landsat TM data were utilized for the multi-temporal change detection Each urban area map was extracted as a base map on the process of multi-temporal change detection. Each urban area map was converted to bit image by using boolean logic. Various urban change types could be obtained by stacking the urban area maps derived from the multi-temporal data using Geographic Information System(GIS). Urban change type map was created by using the process of piling up the bit images. Then the urban change type map was compared with each land cover map for the change detection. Dalseo-gu of Daegu city and Hwawon-eup of Dalsung-gun, the fringe area of Daegu Metropolitan city, were selected for the test area of this multi-temporal change detection method. The districts are adjacent to each other. Dalseo-gu has been developed for 30 yeais and so a large area of paddy land has been changed into a built-up area. Hwawon-eup, near by Dalseo-gu, has been influenced by the urbanization of Dalseo-gu. From 1972 to 1999, 3,507.9ha of agricultural area has been changed into other land uses, while 72.7ha of forest area has been altered. This agricultural area was designated as a 'Semi-agricultural area'by the National landuse Management Law. And it was easy for the preserved area to be changed into a built-up area once it would be included as urban area. Finally, the method of treatment and management of the preserved area needs to be changed to prevent the destruction of paddy land by urban sprawl on the urban fringe.

  • The purpose of this study was to predict the future urban activities effectively and rationally. For the purpose, a simulation model, based on SD, was built by integrating economic activities, land use and traffic of a city and by dividing Daegu Metropolitan City into seven districts and one county. To identify the effect of the development of a new city in the Dalsung County area, the future population and traffic volume of the city were predicted, using the model. The results are summarized as follows. The future population according to the development of a new city in the Dalsung County area was predicted, and the effects before and after the development twenty years later were compared. The future population of the Dalsung County was found to have slightly increased, whereas that of the adjoining Dalsuh Metropolitan District was found to has slightly decreased. For the other districts, there were no changes of the future population. It was found, therefore, that the development of a new city would have no effect on other districts. Then, the traffic volume according to the development of a new city in the Dalsung County area was also predicted. It was found that in the initial stage the traffic volume would increase with the increase in population of Dalsung County. It was predicted that particularly,. the traffic volume for the purpose of business would greatly increase. The traffic volume of Dalsuh Metropolitan District showed a slight decrease, whereas for the other districts, there were no changes of the traffic volume.

  • This study starts from the architectural and urban interest to integrate the daily life and behavior of residents in the city of Seongnam and to sustain the community. A fixed abode is something that can not be separated from the place and should be approached from a comprehensive perspective reflecting the physical and social conditions of the region. Although residential neighborhoods have a residential walking range, which has a steep slope, it has been formed in the suburbs of the residential area where commercial facilities are activated organically. The humanities and social organizations of the residents are integrated with the physical space and act as constituent factors of major cities. This is an attempt to suggest improvement and activation of existing cities based on their daily lives, rather than destroying cities and creating new ones. Also, it is proposed to 'Neighborhood Street' as an indicator of a uniform urban renewal plan for existing urban regeneration projects. Based on the definition of the city of living in the city, the center of the city will be located in the center of the city, and it will be the center of the city's bustling streets.

  • In recent times, multi-centralization and decentralization as well as large Capital area and suburbanization in the spatial structure of capital area. With rapid growth, urbanization and industrialization are unsystematic, and growth inequality between regions caused negative effects such as discordant centralization and decentralization, fluctuating land value, and gap between living conditions. Accordingly, this study analyzed urban spatial indexes by the self-governed body in the capital area such as Seoul, Incheon, and Gyeonggi province for the analysis of the regional inequality phenomenon. We examined the characteristics of temporal and spatial changes in urban spatial structure in the capital area by utilizing the distribution pattern and density of city indexes such as population, employment, etc, and then drew the commonality of those factors through factor analysis. We evaluated the drawn results through the city standard index by each city, conducted factor score analysis, and identified the interaction between each factor and Housing Purchase Price Composite Indices index, housing rent price index(Housing Jeonse Price Composite Indices), land price fluctuation rate, diffusion ratio of house, and financial independence.

  • This study is based on the need to reform mixed use plan of school facilities considering the characteristics of depressed downtown area. It started with the object to make a plan by deducting function of place required and corresponded to the characteristics of depressed downtown area in Pohang city. As the result of researching present status and the characteristics of six elementary schools in Pohang which the number of student has decreased, it is found that they are required to have change in the region of depressed downtown area which have fallen behind and obsolete school facilities which idle classrooms have increased and to have reformations of a city are characterized by 5 types as poor life environment, lack of cultural facilities as community institution, poor open-space and ecological environment, non-activation of conventional market and contraction of commerce industry by outflow of industry, transfer of administration operation function and etc. and the region of school under researching shows these characteristics. I planed the mixed use program with factors of local community facility, status of school facility use and depressed area's characteristics. Finally, I propose the mixed use plan of school facilities as the strong point of sustainable development which influences on and be influenced by regional characteristics and structure of city.

  • Throughout the modernization which was dominated by development theory in Korea, land use planning for housing tended to spoil the environment. Numerous studies, however, pointed out the problem of this development-led planning and there was a broader consensus that the past planning was part of the environmental problem of inner city. These observations changed the development-led planning into the environmental friendly development planning. In particular, Seoul Metropolitan Government held the international planning competition to develop 'Sangam' as an environment friendly residential area. With this plan 'Sangam' would be the sustainable residential area with the harmony of nature, human and technology. Furthermore it would be the outset of the long-term plan to develop 'Seoul' as a 'gate-city, an 'information-city' and an 'eco-city'. To do this, it needs especially the planners' and the constructors' constant concerns and efforts as well as the citizen's participation.

  • 도시의 발전정책에 대한 주민의 인식과 평가태도는 정책의 성공여부에 커다란 영향을 미치기 때문에 지역정책의 수립에 중요한 변수로 작용한다. 본 연구는 역사.문화적으로 전남 동부지역의 중심지로 성장해 왔고, 오늘날에는 광양만권의 중심도시로 기능하고 있는 순천시를 사례로 도시발전정책에 대한 지역주민의 인식태도를 고찰한 것이다. 도시발전정책에 대한 시민들의 인식태도를 파악하기 위하여 정주환경과 삶의 질, 도시발전정책의 문제점, 그리고 장기적인 방향에 대한 내용을 중심으로 설문지 조사법을 이용하여 자료를 수집.분석하였다. 순천시민들은 순천시의 삶의 질에 대해 비교적 만족하고 있고, 지역경제의 활성화와 문화.여가시설을 비롯한 생활편익시설의 확충에 많은 관심을 가지고 있다. 순천시 도시발전의 미래상에 대해서는 긍정적으로 인식하고 있으나 장차 교육과 문화기능의 강화를 중점을 두고 시정을 추진해야 한다고 평가하였다. 따라서 순천시가 광양만권에서 중심도시로 기능하기 위해서는 주민의 요구를 수렴한 새로운 유형의 도시발전정책의 수립과 시행이 필요한 것으로 밝혀졌다.

  • Objectives: This study evaluated the effect of construction on ambient PM-10 in the surrounding area. Methods: Four study sites were selected from total AAQMN 11 points in Daegu city. All the four study sites were located near under or completed construction. Mean monthly PM-10 in 2007 to 2013 were analyzed. Results: Impact of residential construction on PM-10 was more obvious than industrial area. PM-10 was positively associated with number of construction near the study site. When there were 2 or 3 construction sites, PM-10 level was higher. Wind direction and the surrounding terrain affected PM-10. Conclusions: Construction has a strong influence on PM-10 in the surrounding Area. Reduce PM-10 there is the need for special construction site management. Proper management is required to minimize fugitive dust in construction sites.
