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.

In practice of urban redevelopment promotion projects, since the decision-making is dependent on the verbal agreements between the participants, planning changes are frequently occur. A master plan can be utilized as an effective feedback and adjusting means for decisions. It is a difficult to establish a master plan quickly and effectively to consider the large number of information. Effective decision support system that can storage and retrieval information items systematically and efficiently necessary when planning master plan is required. In this study, a data-warehouse prototype that supports the master planning at early stage was suggested. A metadata index database was developed by identifying information items of base survey results and master plan cases. Also user interface for information searching was presented. The applicability of the prototype was evaluated by case application. It was found that the prototype allows effective searching of desired information through meta data.

The $18^{th}$ century's Industrial Revolution brought about influx of commerce, industry, and agricultural population into the urban areas, entering the $19^{th}$ century. Quality of rural communities declined, and the exploding population in the cities gave rise to various problems. 'Mietskaserne' Blockhousing was constructed by the 'Hobrechtplan', but led to social problems such as poor living conditions, insufficient sunshine due to overcrowding, slums due to incomplete urban infrastructure, epidemics, and so on. Starting in the early $20^{th}$ century, Berlin has driven forward a remodeling plan under the motto of 'critical reconstruction (kritische Rekonstruktion)'. It is performed in the place, which represents the vicissitudinous history of Berlin with site plans coexisting past with presence, using modern vocabulary of architectural forms. Reconstructing a city is a process which not only raises the economic value of each building consisting a city, but also a redevelopment process that brings out cultural value of an era. When a new era emerges buildings get reconstructed or rebuilt, and thereby form the identity of a city by reflecting its society, culture, politics, economy, and history. Old German architecture were not destroyed or rebuilt recklessly just by the fact that they are functionally or aesthetically outdated. Each building is treated as precious cultural heritage reflecting the history. This is how Berlin is being transformed today.

ent years, the change of urban function and the decrease in birth rate have given rise to merge, abolition and relocation of the existing schools. This study explores the possibilities for various land utilizations of relocated school sites, using the trial case of 'A' elementary school in Eun-pyeong gu, Seoul. 'A' elementary school has happened transfer plan due to the urban development project of the redevelopment area, Eun-pyeong gu in Seoul. Firstly, it studies the land use categories and the development methodologies of 7 relocated school sites happened in Seoul. In addition, it analyzes the land utilization after relocation, development principals, area, building usage and changes in land use regulation. Finally, it proposes the commercial exploitation of school site targeting 'A' elementary school site. Throughout the profit analysis, this study concludes that it is available to exploit the relocated school sites by the variety of development methodologies, especially in a metropolis like Seoul.

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 purpose of this study is to identify the supply status and planning trend of North Korean housing through analysis on the North Korean architecture specialized media data. The flat composition is changing and the living room is becoming the center of the houses. Also, in the urban areas, the standard apartment type is four apartments in a row and the plan form is getting diversified into circle type, Y type, and irregular type. On the other hand, in the rural areas, two houses in a row and single house are typical and the change in planning scale and space structure are not substantial. Since the 2000s, design changes have been made to emphasize the third dimensional structure of buildings such as the elliptical houses and L-shaped houses. Furthermore, 8~10 households are located on one floor which leads to the tendency of the building enlargement. In terms of house size, a square concept was introduced to replace the initial 2~3 room concept and the basic module of the room planning the 3 room house based on $3m{\times}3m$. However, there seems to be no standard house size, and the house size may differ depending on the social classandregion. In the early 1980s, when there was focus on the apartment complex construction, the high-rise apartment buildings of 30~40 floors was planned. However, during the Pyongyang redevelopment project, apartments of more or less than 10 floors were built and row-houses of more or less than 4 floors were built. In terms of the complex scale, a lot of small complexes of around 300 households are emerging after 2010. The construction projects are mainly limited to specific regions such as Pyongyang and Samjiyeon, and also limited to specific classes such as the workers and soldiers initially and the scientists lately. In addition, living boundary composition and ancillary facilities for sufficient green area ratio securement and the people of North Korea are maintained consistently. In recent years, the specialized floor planning such as solar house and the house for the disabled people, framework houses for redevelopment business, and multi-storied house construction technology are also emerging.

Recently, the expansion of social infrastructures and urban redevelopment, the construction works have been a rapidly increase. The subway's noise and vibration are on a continuously increasing status in its importance as by the industrial and cultural development process. Nevertheless, in our country, adequate alternative idea for the construction noise and vibration are not yet established. In this point, the purpose of this study is to know the vibration effect to the structure. This study was used to determine the standard of vibration and the way of losing vibration. The case of construction site is a good example. The data of this study was obtained by a construction company in Korea. Vibration effect could cause structural problems and affect human mental state. The results of this study are as follows; check the vibrating point, determine the suitable limit of vibration, make a good plan and construction.

In recent years, various perspectives on the sustainable regeneration based on culture, history, identity, and the ecosystem have arisen in attempt to harmonize the environmental, economic, and social issues of the city. However, these ideas did not consider the importance of urban structure for sustainable regeneration. This research attempts to reveal the fundamental characteristics of sustainable regeneration of Lubbock, Texas in the United States through the analysis of urban structure, city planning and city regeneration planning. Despite the 300% expansion of city area in the 1950s, since the 1970s Lubbock's civic center has decreased in population due to middle class migration into southwestern and western suburbs. In the 1980s, a redevelopment organization was established, and a private sector-centered regeneration plan was implemented. In this study, a new approach for urban regeneration was introduced, resulting in strategies focusing on the linkage of urban regeneration into the characteristics of the entire city.

Fresh Kills is the largest landfill in the world located in the west side of Staten Island, New York. The landfill served as a storage area for New York City's trash for more than 50 years. After years of civilian and political pressure, state and local legislation decided its closure of landfill operation in Fresh Kills in March 2001. Soon after, Department of City Planning announced a Fresh Kills international design com-petition: 'Landfill to Landscape'. The winning entry was promised to be outline for the redevelopment of the 2,200 acre site which the size of three times Central Park. Forty-eight teams representing more than 200 offices from around world submitted proposals, from which six finalists that mostly led by landscape architects were selected. In December 2001, a jury of architects, landscape architects and city officials unanimously selected Field Operations as the winner. The plan, named Lifescape, visualizes the gradual 20-year transformation of the whole Staten Island into a 'natural lifestyle island' recognizing that Staten Island is home to coastal wetlands that shelter one of the most diverse ecosystems in the New York metropolitan area. It suggested that an ecologically reconstituted Fresh Kills could become the center of integrated parks and greenways system on the island otherwise fragmented. The project will be one of the largest and most ambitious undertakings in the metropolis in years developing a complex web of habitats and parklands on top of mountain of trash. This study tries to achieve two goals: One is to provide general explanations on the project, Lifescape, breaking down to its background, geographical context, design concepts and phased development plan. Another is to introduce the unique and innovative design approaches by Field Operations that are different from a conventional landscape architectural attitude. Since this project was well published through many magazines and newspapers, main focus will be upon aspects that differentiate this project from usual landscape projects. Conceptually Lifescape brought provocative notions on nature/culture relationship and the role of urban park as an active agency rather than just a green rest area. Also this project introduced pioneering graphics like plan collage, diagrammatic plan, phasing diagram and photo montage as vehicles conveying information, imagination and provocation. Witnessing the influence of the project gradually in the field of academic and practice in the States, this study is intended to become a constructive reference to similar landscape projects dealing with large and complex urban context in conjunction with restructure of contemporary city.
