This study analyzed the influencing factors for urban redevelopment projects with a relatively long project duration in the context of Seoul's increasing urbanization rate and aging. Among the business areas that have been designated since 2005 and have been approved for the management and disposal plan of the entire Seoul area, 75 business areas have been set as targets. A hedonic price model was used to analyze the project area, economic, and locational characteristics as independent variables with the project duration from designation of zones to approval of management and disposal plans as dependent variables. As a result of the analysis, the smaller the project area, the larger the area occupied per union member, the larger the land price change rate, and the smaller the KOSPI index, the shorter the required period. This study has the distinction of empirically analyzing the effect of characteristic variables considering size and economic and locational characteristics on period. It provides implications that the area of the business area, the number of union members, and economic conditions should be considered when establishing a business area.

The urban renewal type redevelopment project is a project to improve the urban environment for the recovery of urban functions and revitalization of commercial districts in commercial and industrial areas. Urban regeneration projects are not progressing smoothly. The urban renewal type is not so for landowners, who require a high level of professional knowledge and experience to carry out smooth projects. In addition, the core part of business conflicts can be seen as the problem of management and disposal methods. Therefore, as landowners, etc. become the actual subjects, the public will take charge of project execution, but all development gains and losses will be attributed to the owner of the land, etc.

This research aims to find the issues and explore policy agenda of contributed acceptance of urban renewal project. Through the analysis of urban renewal project in Seoul, three isssues was found as follows. Firstly, the ratio of contributed acceptance in each district was quite different. Secondly, the donated land was scattered around whole project area. Thirdly, infrastructures are not constructed until all renewal projects were implemented. For this issues, this research proposed that a proper standard of the ratio of contributed acceptance is needed and land donation should be designated to adjacent lot or block. Also public support should be for developing urban capacity and completing infrastructure.

Urban renovation projects (reconstruction and redevelopment) have a longer licensing period than general housing projects, and many consultations with the licensing authorities require expertise. Most of the members of the union do not have basic knowledge of the maintenance business, so they have a lot of authority to promote smooth business Is entrusted to the union leader. However, contrary to the original purpose entrusted by the members, it is easy to find a case where the business is suspended because the union leader is exposed to corruption for the private interests of the union, and the members' disputes could not be resolved. In order to overcome this risk, the problem of the maintenance project was found through a questionnaire survey composed of practical experts, and a solution was presented through the KCSI evaluation model. This study mentioned the necessity of a responsible CM that can make independent business decisions without interference from the union, rather than a management-type CM limited to the cooperative's work assistance. In order to promote the construction industry's national role, it was necessary to revitalize responsible CM, so six practical alternatives were proposed.

낙후된 도시를 정비하는 방법으로 새로이 등장한 거점확산형 주거환경개선사업은 전면철거방식인 주택재개발사업이내 공동주택 건설방식과 비교하여 지역주민의 재정착 비율이 높고, 기존 도시 조직을 고려하며 점진적으로 개발할 수 있는 기성시가지 정비수법으로 주목받아 왔다. 또한 지역의 침체된 경제를 활성화시키고 황폐화된 구시가지를 회복시키기 위하여 정부에서는 도시의 새로운 경쟁력을 찾고 지역 주민의 삶의 질을 보장하기 위해 지역 주민의 삶의 질을 보장하기 위해 지역 커뮤니티를 근간으로 하는 도시재생사업을 추진하게 되었다. 효과적인 거점확산형 주거환경개선사업을 위해서는 주민참여가 중요하며, 현재에 이르러서는 필수적인 요건이 되었고, 도시계획 역시 주민과 함께 하는 방향으로 변화하게 되었다. 이에 따라 GIS도 주민과 같은 비전문가의 의사결정을 지원하기 위한 도구로 확대되어 활용되고 있다 하지만, 현행 주민참여 방식은 형식적인 수단에 불과하며, 주민 참여도를 높일 수 있는 획기적인 방법은 아직도 연구해야할 과제이다. 따라서 본 연구에서는 커뮤니티의 재생을 목적으로 하는 거점확산형 주거환경개선사업에서 능동적 주민참여를 좀 더 효율적으로 이끌어 내고자 사업정보제공서비스, 주민의사반영 서비스, 쌍방향적 의견교환서비스, GIS 서비스를 제공하는 커뮤니티 재생을 위한 앱 기반 PPGIS 모델을 제안하였다. 최근 스마트폰의 보급률이 급증함에 따라 스마트폰의 활용은 주민들의 관심과 참여 비율의 변화를 크게 가져올 수 있을 것으로 기대되며, 커뮤니티 재생을 위한 스마트폰의 앱 기반 PPGIS 모델은 정책결정자, 전문가 그리고 주민이 서로의 생각을 교환하고 이해하는데 또 다른 유용한 의사소통 도구가 되어 주민의 참여도를 높여 줄 것이라 기대된다 특히, 스마트폰을 많이 사용하고 있는 젊은층의 흥미를 유발하여 참여도가 낮은 젊은층의 참여도를 높이는데 기여할 것이라 여겨진다,

The government has been operating residential improvement projects through the "Act on the Maintenance and Improvement of Urban Areas and Dwelling Conditions for Residents" as a type of a remedial measure for deteriorated residential areas. However, in recent years, the residential improvement projects have experienced difficulties due to the effects of various factors including the slowdown in economic growth. After observing the depression in a number of projects, various studies have been carried out to investigate the causality and improve the promotion of the residential improvement projects. In the trend of research, this study aims to analyze the effects of land and building characteristics on the improvement projects of Busan Metropolitan City. The dependent variables of the study represent different phases of improvement project as specified in the "Act on the Maintenance and Improvement of Urban Areas and Dwelling Conditions for Residents". The independent variables represent land and building characteristics which refer to the criteria used in the designation process of maintenance area according to the act. The empirical analysis uses the ordered logit model. The results from the analysis suggest that geographical condition, factors related to the number of union members, factors related to the parcel price and condition of a location have impact on the promotion of the improvement project. The results of the analysis show that majority of the factors are related to the economic feasibility of the projects. Residential improvement project is a part of urban planning projects that rehabilitates deteriorated residential environment, and it is closely associated with the quality of life of public. Accordingly, we hope that such projects are reasonable and take effective approach to those with urgent needs rather than to focus on profitability. Also, potential administrative and economical loss should be avoided by taking necessary planning measures in advance.

Transit-Oriented Development Model, which is recently proposed to activate transit use, is suitable for solving environmental erosion problems of sprawl cities with low urban density. Accordingly this model is inadequate to apply to Muti-Nucleated City with high urban density like Seoul. With this background. this study proposes ways to effectively implement changes from automobile-oriented Seoul to transit-oriented city through comparative analysis of the urban design policy of Station Impact Zone (SIZ) of Seoul and Transit-Oriented Development Policy of Singapore and Tokyo. First, the study suggests that the implementation strategies for Transit-Oriented Development in the job-oriented SIZ and the neighborhood-oriented SIZ should be made separately. In addition, the job-oriented SIZ should be designated as 'Strategic Centers' in Seoul Comprehensive Plan in order to make Transit-Oriented Centers. Lastly, the SIZ should be designated as 'the Empowerment Zones' in order to make the blighted areas around stations viable for redevelopment and new incentive system should be applied to activate setting up transit-transfer facilities.

Safety accidents are increasing, such as changes in groundwater levels due to construction work or natural influences, or ground cave-ins caused by soil runoff from old water supply and sewage pipes. In addition, underground facility management agencies must make efforts to improve the accuracy of underground information through continuous investigation and exploration in accordance with the Special Act on Enhanced Underground Safety Management. Accordingly, in this study, we defined the configuration of equipment and data processing method to collect 3D precise exploration underground facility information and developed 3D underground facility information collection technology to ensure accuracy of underground facilities. As a result of verifying the developed technology, the horizontal accuracy improved by an average of 6cm compared to the existing method, making it possible to acquire 3D underground facility information within the error range of the public survey work regulations.

This study concern with the changes of street from the Choseon Dynasty to present days around Old-Boundary in Taegu, analyzing the backgrounds of change factors and development trends of the Taegu City. The basis element of a city structure is the street. Therefore, in this study, a chage of street space of a city was investigted. Historically, Taegu was a walled city and had a Mono-nucleus which was restricted by the castle, and served as a starting point of formation of spatial structuure. The form of the artery street took a "T" pattern, othe streets were formed in irregular shapes. As the city grew gradually, the castle was removed on account of diversification in traffic network, change of socio-economic organization in traffic network, change of socio-economic organization, formation of industrial bases and functional distribution. CBD of this city has been located within the area surrounded by these streets. This is a kind of general pattern of traditional walled cities through the world in both Western and Oriental societies. A s the begining of this centry, a 'Dark Ages' descended upon Korea because the country was under the Japanese-Korean Annexation, and, throughout this period, the urban planning was planned exclusively for Japanese. The street pattern within residential areas of Korea took the maze type, in contrast with Japanese residential areas which showed grid pattern of streets. This is another general pattern of almost of all colonial cities especially in Asia. High class residential areas were planned and built by Japanese, and they were located within 5-10 minutes' on-foot distance from the CBD hard core. This high prestige has continued until the 1980s when it occurred land use succession which commerical functions invaded into residential areas. Back in the colonial period, there was a between two hetrogeneous groups due to the fact that the Japanese lived mainly oriented the new railway system but that Koreans still lived along the old highway system which ran through the Korea Peninsula. Street netwook formed in the above process has maintained its shape without great changes after the liberation form the Japanese Colony. Taegu has, accordingly, developed ring-radial network system which has been a combination of radial and ring facilities. The present conditions of street patterns in Taegy mainly depend on 4 rings and 8 radius, with grid pattern street able to be found in Old Boundary.
