On last year's KSR conference, the general of systems engineering technology was introduced on the focus that the SEMP(Systems Engineering Management Plan) being applied for a national project of 'Urban Maglev Program'. Since this SEMP covers very wide work scopes of 'plan, application, control of the program', 'design, analysis, test & evaluation of the system', and 'special engineering activities', it is very important that the tasks and responsibilities of all participants of the project, involving the tasks to collaborate between them, are clearly defined and described. By the point, the updating of SEMP should be done continuously. In this paper, the updating points and typically the management plan of TPM (Technical Performance Measurement), which is more concretely defined, will be explained.

To develop the most effect maintenance system of urban MAGLEV train which is being developed based on system engineering, logistics belong to special system engineering were applied to maintenance system and Integrated Logistic Supports (ILS) were employed to tailor every step of MAGLEV project. Since ILS had not been applied to domestic train project, the followings were studied to validate ILS: 1) case studies on maintenance procedures at home and abroad, 2) overview of standardized process of ILS, 3) Comparison and analysis of relationship between RAMS and ILS, 4) Application of ILS to MAGLEV maintenance system and other domestic train system.

It is recommended that the villagers should organize their own council based on the resources which the village owns to manage the experience programs in the experience village, but it is criticized that there is no consideration about inhabitants abilities when the project is about to be constructed and the programs is developed. This research is purposed to develop the manual which is depending on urban-rural correlative experience programs conduct that is developed by the test to increase inhabitants abilities effectively. Therefore, the manual of the programs should be utilized as a early guide to help the village jump up to the standard level of program procedure, and the inhabitants should create ideas continually to develop better programs on the basis of the manual rather depending on the manual. And for another, the manual should often be upgraded to understand the process of historical changes of the village.

Maglev is a non-contact traffic system in which cars are supported by magnetic force instead of wheels. This is a ground-breaking traffic system providing superior environmental friendliness and cost efficiency due to the minimal noise and vibration offered by its non-contacting nature. We study the present specification and performance of the low speed urban maglev system in Korea and other countries. After set up the test line, to success the "Commercialization of Korean Urban Maglev System" project, we establish proper requirement of maglev system in Korean environment on base of "Daejeon National Science Museum Maglev Establish Project".

This research and technology development project is based on the concept and plan of Sumitomo Forestry Co., Ltd., and designed by Nikken Sekkei Ltd., and is aiming to realize 350 m supertall timber-framed buildings in urban areas by 2041, the 350 year anniversary of Sumitomo Forestry's founding(Fig. 1). By constructing office-based multi-use buildings which have 70 stories above ground with GFA of 455,000 ㎡, using a huge amount of timber of 185,000 ㎥, this project envisions to connect forests and cities, and to solve the problems in both of forests and cities. At the present stage, the main objective is to identify the issues related to wood, such as building structural systems, construction methods, materials used, and resource development, and to create a roadmap for future technologies to be researched and developed.

This paper summarizes the results of a two-year-long research project conducted by the CTBUH on the life cycle assessment (LCA) of tall building structural systems. The research project was made possible thanks to a $300,000 contribution from ArcelorMittal and the support of some of the most important structural engineering firms and players in the tall building industry. The research analyzed all life phases of a tall building's structural system: the extraction and production of its materials, transportation to the site, construction operations, final demolition of the building, and the end-of-life of the materials. The impact of the building structure during the operational phase (i.e., impact on daily energy consumption, maintenance, and suitability to changes) was also investigated, but no significant impacts were identified during this phase.

Recently, new methods have been developed for estimating the current and recent changes in effective population sizes. Based on the methods, the effective population sizes of Korean populations were estimated using data from the Korean Association Resource (KARE) project. The overall changes in the population sizes of the total populations were similar to CHB (Han Chinese in Beijing, China) and JPT (Japanese in Tokyo, Japan) of the HapMap project. There were no differences in past changes in population sizes with a comparison between an urban area and a rural area. Age-dependent current and recent effective population sizes represent the modern history of Korean populations, including the effects of World War II, the Korean War, and urbanization. The oldest age group showed that the population growth of Koreans had already been substantial at least since the end of the 19th century.

Abeno Harukas is the tallest building in Japan and is located in Abeno, which is one of the three main railway transport nodes in Osaka. This building has a height of 300 meters, and its lowest levels are 30 meters below ground. It contains a department store, museum, offices, a hotel, and an observatory. In this urban renewal project, a section of the department store that encloses the station was dismantled and replaced by a supertall building complex, while infrastructure was simultaneously constructed, including: upgrades to the station and the existing department store, improved connections to the subway and pedestrian bridges, and a new pedestrian walkway over the road. In this paper, the ingenious erection processes, newly developed technologies, and precise construction management techniques are introduced for Japan's tallest building.

Restoration to improve the ecological quality of Mt. Nam was explored in a viewpoint of restoration in both landscape and ecosystem levels. A restoration plan in landscape level was based on the result on the land-use pattern in Mt. Nam including its surrounding area and that in ecosystem level on the ecological quality of each landscape element. A plant to construct the green network, which extending from Mt. Nam to the Han river through the Yongsan family park and through the Eungbong urban park was prepared as a restoration project in landscape level to improve the ecological quality of Mt. Nam as an ecological park. On the other hand, a plan for restoration and creation of biotop as a restoration project in ecosystem level was also prepared to improve the ecological quality of each green area consisting green network. Green areas composing green network include keystone green area (Mt. Nam), green stations (Yongsan family park, Eungbong urban park, and the han river citizen's park), and green pathway (or ecological corridor) connecting those green areas.

Parks in Kwang Ju ar determined by the development of a housing project under the regulations of land development rather than the planning approach of park provision. This study tries to identify who is the provider of parks, to estimate the size of urban parks per person in the area of the housing project, to look at the spatial allocation patterns of park provision and to identify the character profiles of users and the social profile of an ares(Dong). This research has produced the following major conclusions : 1. The city government should set up a master plan of park provision to control park delivery system to avoid maldistribution. 2. A positive discrimination policy should be introduced to disadvantaged areas in terms of park provision. 3. The null hypothesis - there is no relationship between distance and park Use - is rejected by the correlation rate of 0.4984. 4. The ratio of parks per a person ; 10.43㎡/person in 1990 has decreased to 10.41㎡ /person in 1994. This means that the increase of parks in terms of quantity could not catch up the increase of population.
