This study suggests Compact City type urban development strategies and planning elements with the purpose of sustainable development. The suggestions are based on analysis of the development projects promoted in the cities within Green-Belt. Following are the findings of this study: First, in the late 20th century, Compact-City has been suggested as standard of sustainable urban development in the developed countries, and this promoted urban development plans were presented in detail. Second, The development plans are suggested plan elements by urban environment, space, community, and management. It was classified as an applicable element in Green belt and Compact City type. Finally, after comparing several city development projects (Gwacheon, Uiwang, Hanam), differences and Limitations between the Compact-City type urban development. Considering analysis of this study, urban development projects in Green Belt should be prepared to sustainable Compact city type urban development.

Muan Enterprise City is a mega-project that has an investment worth up to $3 billion only in the construction of infrastructure. The project's success will largely depend on the success of its construction management. This study sets out to establish a construction management plan for Muan Enterprise City by defining the core objectives and organizational structure and its supporting system. Project outline and core objectives were analyzed, and necessity of construction management and processes evaluated. Based on this analysis, implementation strategy for the achievement of project goals was defined and developed, and organizational structure and its support system to execute established. This study strives to support the project's construction management being carried out under proper planning and possibly set an example for construct ion management of mega-structures in the future.

This paper assessed the weights of attributes in creating transit malls. The aim of the creation was classified as travel demand management and urban revitalization. The attributes were grouped into four aspects, or 4As: attraction, amenity, accessibility, and activity. These dimensions represented land-use, urban design, transport, and socio-cultural characteristics, respectively. The analytical hierarchy process was applied to explore the weights. Accessibility(52.7%), attraction(25.6%), amenity(13.7%), and activity(8.0%) were the order of magnitude in weights for the purpose of travel demand management, while attraction(36.1%), accessibility(30.6%), amenity(17.7%), and activity(15.6%) were that of urban revitalization. The multi criteria analysis also showed different size of weights in the sub planning attributes. These results indicate that the aimin implementingtransit malls should be differentiated and highlight that the combined land-use and transport plan is essential for the successful development. Car accessibility and socio-cultural characteristics are also understood as the important factors.

지하매설물이란 땅속에 묻혀있는 상수, 하수, 전기, 통신, 전력 등 도시기반시설을 의미하며, 지상시설물에 비해 관리가 어렵고 예기치 않은 사고로 인해 많은 재산상, 인명상 피해를 입힐 가능성을 안고 있다. 우리는 서울 아현동과 대구에서의 대형 가스폭발사고, 도로굴착공사가 끝난지 얼마 안되는 지점에 또다른 매설물의 매설 또는 유지보수를 위해 중복공사가 일어나 교통에 혼잡을 유발하게 되는 경우를 빈번하게 경험하면서 도시의 동맥역할을 하는 이러한 지하매설물에 대한 체계적 관리가 시급함을 실감하게 된다. 특히 선진외국에서 GIS를 도입하여 지하매설물을 데이타베이스화하고 지하매설물 관리체계를 개발하여 지하매설물을 체계적으로 계획하고 관리하며, 대형사고를 사전에 예방하고, 사고가 일어난 경우에는 GIS를 활용하여 보다 신속하게 대처함으로서 피해를 최소화하는 실정을 감안할 때 GIS도입이 이러한 매설물에 대한 체계적 관리를 가능하게 하는 방안으로서 적극적으로 검토되어야 함을 느낀다. 본 글에서는 첫째, 이러한 지하매설물의 관리실태와 문제점을 분석하고 둘째, 현재 국가 및 서울시에서 추진 또는 계획 중인 지하매설물 관리체계 구축사업내용과 셋째, 지하매설물 데이터베이스가 어떻게 구축되고 유지.관리되어야 할 지에 대하여 간략히 살펴보고자 한다.

Landuse information is used to plan land use, urban and environmental management as base data. And, demand for landuse information is rising due to ecological consideration. But existing method to extract landuse information from aerial photographs or field survey is consume a lot of time and cost. In urban area where the pattern of landuse is densely aggregated, a landuse information needs to be classified in detail for urban planning and management. Therefore this study aims to examine the method to extract landuse information in detail from 1:1,000 digital topographic data. For the purpose, the method was applied to a part of metropolitan Seoul. The results of study shows that extraction of landuse information except forest area is possible. Forest area is needed to describe smaller spatial unit. For the future, the method of describing forest area is improved it will be effectively applicable for the city maintenance.

Many studies on bus scheduling optimization have been done from the 1960s to recent years for establishing rational bus schedule plan that can improve convenience of bus passengers and minimize unnecessary runs. After 2000, as part of the Intelligent Transport Systems (ITS), the importance of the schedule management and providing schedule information through bus schedule optimization has become a big issue, and much research is being done to develop optimization models that will increase bus passenger convenience and, on the side of bus management, minimize unnecessary bus operation. The purpose of this study is to calculate the optimal bus frequency and create a timetable for each bus stop by applying DTR or DTRC model that use data for each bus stop and route segment. Model verification process was implemented using data collected from bus management system (BMS) and integrated transit-fare card system for bus route of Seoul's No. 472 line. In order to evaluate the reliability and uncertainty of optimal solution, sensitivity analysis was implemented for the various parameters and assumptions used in the bus scheduling model.

This study was performed with the purpose of providing basic data for the improvement of zoning regulations of urban nature park by analyzing the present problem which occurred during last 6 years from the year of 2005 when the program was introduced for the first time. The study was processed first by the analysis of the cases of problems evoked by citizens, second the other problems was delineated by interviews of officials, at last the validity of all of the problems was verified by a group of professionals through delphi method. The results can be summarized as follows. 1. In relation to the designation and management of urban national park areas, designation criteria, designation process, maintenance, laws and regulations and 20 other items were found to be problematic. After Delphi method, 5 items were removed and 2 added. The results showed that there were 17 problematic items in total. 2. Regarding the problem of criteria for designation, which are, lack of priority(weights), lack of objectivity due to the difficulty to use quantitative evaluation method, incompatibility for contaminated land environmental impact assessment, incompatibility of land suitability assessment, lack of detailed field survey standards, lack of national park area standards, and 6 other items. 3. Regarding the problem of designation process, which are, the occurrence of civil appeals for designating a new national park, the needs of feasibility study on the urban national park areas constructed before urban national park guidelines came out, lack of a comprehensive review of the boundaries set when determining national park area management plan, poor temporal and financial conditions for an accurate field survey, and 4 other items. 4. Regarding the problem of maintenance management, which are, lack of management system in each space, lack of effectiveness of Urban Nature Park Area Management Plan among master plans for park and green areas, the occurrence of dual managers due to dual natures such as purpose area and city park, lack of professional manpower to manage park areas, and 4 other items. 5. Regarding the problems of regulation guidelines, which are, lack of separate urban park area management plan, incompatibility of the permitted facilities in the park to the park area standards, lack of feasibility study on urban park areas, and 3 other items.

The high density of population and building; can cause catastrophe in urban areas when natural or artificial disasters break out. The aim of this paper is to assess comprehensive disasters risk of urban areas by Geospatial Information System. For this purpose, we classified disasters risk of urban areas into low categories: flood, fire, building-collapse, and shelter, and then determined factors for hazard risk assessment respectively. The results of hazard assessment can be applied to minimize the demage of disasters in establishing the urban management planning. For more systematic and professional approach the further research is need to consider more disaster assessment factors and join with related experts.
