The production of waste concrete is increased continuously by urban renewal, reconstruction, remodeling, and so on. So the positive use of recycled aggregate concrete is needed. Research for recycled aggregate concrete that use recycled aggregate from the mid-80s to solve environmental problem of aggregate insufficiency and waste concrete is consisting vigorously. However, specifications and mix design about waste concrete's use are evading use of recycled aggregate concrete yet in spot being not taken a triangular position. Therefore. it analyze existing research data for recycled aggregate concrete collection to develop strength estimate program in this research. Recycled aggregate concrete's strength estimate program if specifications and mix design about recycled aggregate concrete are taken a triangular position to foundation recycled aggregate concrete's practical use to increase judge.

With the rapid changes in healthcare system, the impact on healthcare design is significant and constantly changed. Because of emergence of new technology, far-advanced methods of healthcare delivery, and changing social and environmental issues, the healthcare planners and architects have to make sure that future expansion are taken into consideration when they design the hospitals. This thesis aims to investigate the hospital remodeling cases in Korea and USA and find the solutions for the vertical expansion of the hospitals in the metropolitan area where the buildings may be limited to be horizontally expanded. The M Cancer center in Manhattan, NY is selected to be carefully investigated and analyzed. Based on this analysis, the strategy for the vertical expansion of the hospital will be suggested.

It is to be profound that the population in rural area has been decreased, as a greate number of people have moved to urban area, in accordance with rapidly civilization in Korea. In 1990's years, it is become to as the social problem. As a result, many elementary schools in rural area were to be closed. Closed school facilities were used as a community facilities in rural area, but that reusing rates and method is not systematic. A decline in the work of construction is need to involve with the interior and remodeling. The purpose of this study is to suggest the effective employment and using methodology as a community facilities of closed school in rural area.

In the past few decades, the global population growth and rapid economic development have resulted in significant increases in building energy consumption. To reduce greenhouse-gas emissions and building energy consumption, building materials and energy technologies must be optimized. Building retrofitting is a more efficient method than reconstruction to improve the building energy performance. In order to improve the energy performance of existing buildings, this study proposed energy-efficiency retrofit plans and derived cost-effective retrofit plan. The energy efficient retrofit method is achieved through the packaging of energy technology and the energy and cost reduction effect of the energy efficiency retrofit package are analyzed. As a result of the study, the energy-efficiency retrofit package showed an energy reduction effect of up to 60% or more and a construction cost reduction of about 30%. This study argues that optimal energy and construction cost reduction of existing buildings are possible through the packaging of energy efficiency technology.

As the life cycle of buildings is expected to increase, new constructions will decrease and the proportion of remodeling and repair will increase. Therefore, there is an increasing need for overall performance management of old buildings. In 2020, the proportion of buildings over 30 years old is expected to reach a half. As a result, the demand for securing and improving the performance in the stage of using the building is increasing due to the change in the demand for the building, such as the decrease in the construction permit and the increase in the use of the existing building. From this perspective, the study sought to consider institutional measures to organize the preventive and conservative maintenance of buildings. For this purpose, the conceptual goals of inspection for building maintenance were set through a literature review, and the status and problems associated with building maintenance were analyzed to suggest ways to improve the inspection system for building maintenance.

In recent years, the government's urban housing expansion policy has resulted in increased construction and remodeling work of residential houses and apartments, causing more industrial accidents at elevator installation sites. Typically, accidents occur during the installation and dismantling of work scaffolds inside the hoistways or using non-standardized work scaffolds due to their structural instability. In view of this, the present study deals with the development of a standardized elevator system scaffolding that can be safely installed outside the hoistway, securing the work platform inside the hoistway. An improved version of the scaffolding system eliminates the need to enter the hoistway for the scaffolding installation, thereby preventing accidents.

In this study, we focused on 'Adaptive Reuse', which has the concepts of space reconstitution and social and cultural regeneration, so that previously constructed highrise buildings can accommodate various changes in modern society, and new spatial design was developed based on the characteristics of adaptive reuse. We sought to present the concept and direction, detailed strategies, and architectural response elements of space reconstitution for the purpose of realizing the typical spatial reorganization required by modern society and seeking directions and methods of space reconstitution that can be applied to future society. The purpose is to do so.

Because the hatred and phenomenon of NIMBY for charnel house become an issue, it is the actual condition that charnel facilities are not activated in urban. The purpose of this study Is to examine the space plan of charnel house that introduces the community concept; and then shows the way of interior design for charnel house connected with community space. The following researches are drawn based upon the purpose First, the present conditions and general functions of charnel house are considered closely and revised funeral policy that affects the organization of interior space in charnel house is analysed. Second, the case study for chanel house is limited to the indoor types among the existing researches for charnel house plan. Four charnel houses where were built after 2000 are selected for building standard of space organization in charnel house connected with community facility. Third, the concept and function of community space are considered and the space which can accommodate in charnel house is investigated. Fourth, the concept and organizational framework model of charnel house connected with community facility as a intermediate area In urban Indicate. Fifth, the concrete interior plan for charnel house connected with community space is proposed on the design case of charnel house that are located in urban area. The result of this study is expected to reduce a complicated matter with local residents and to have a correct understanding of charnel house in the future as the existing charnel facilities that have financial difficulty should make a remodeling plan including the community space that give mutual connection to area.

Urban style row-rise houses for rent have been supplied to the center of city from the 1950's first half The amount of stock is about 450,000 houses and occupies about 40％ in the private rented house. As for the structure, the 60％ of them is wooden-structure and the rest is non-wooden. Stocks of 57.5％ of the wooden-structure and 86％ of the non-wooden were built after 1981 years. It was 1981 years that the new earthquake-resistant standard was carried out, the improvement of stocks built before 1981 is necessary because those don't satisfy the present standard. To investigate the renovation possibility of urban style row-rise houses for rent, actual situation of two-story apartment at 2,4, and 5 Chome Taito-Ku in Tokyo was surveyed from July to November 2001. The number of building analyzed is 227 ridges among 234 ridges of the surveyed two-story building. 90％ of building analyzed is wooden structure. 1) The site of 88％ building surveyed is close to a road less than 4m width. It becomes the existing non-conformed building in the building construction act. It is impossible to make a renovation such as rebuilding, extension and remodeling because it requires the set back when renovating this type of non-conformed building, 2) The building built before 1981 is almost wooden-structure, and occupies 37％ of the building surveyed, and doesn't satisfy the present earthquake-resistant standard. An improvement of them is needed because the decrepitude of building proceeds. 3) 50％ of openings and 40％ of windows of the building surveyed doesn't use noncombustible materials. Though it becomes the existing non-conformed building, it can satisfy the present standard by replacing openings with noncombustible materials.
