When building with concrete in cold weather, an insulation method of heat curing must be determined, and a holistic curing plan that considers the characteristics of structures, the heat loss coefficient of a curing sheet, the joint condition of the curing materials and the quantity of heat produced by a heating apparatus is an essential prerequisite for protection against early frost damage. But on a number of national construction sites, there have been serious problems in cold weather concreting due to the unreliability of the information obtained from practical experience. In the construction field in Japan, there is a specification for heat curing prepared by Japanese Architectural Society, which provides an equation for calculating heat quantity. It is also necessary to adopt a detailed specification for a standard heat curing method that is applicable to all national construction sites. In this study, the effect of bubble sheets on the economic feasibility of cold weather concrete is investigated through a comparison with the blue sheets commonly prescribed in national construction sites. In conclusion, this study found that bubble sheets had the effect of reducing the cost of curing materials and the fuel cost consumed by a heating apparatus, compared to the use of blue sheets.

This study aims to analyze community support methods and specific attainments of UR rental housing complex S in Japan and examine the present state of community formation.. UR rental housing S is part of the community revitalization support project launched by UR Urban Agency for creating exchanges among residents in the rental housing complex and in this study, the community support project from February to November 2013 was considered. As community revitalization support tasks, five types of events and exchange meetings were held. While the events and exchange meetings continued, even the residents who did not join the residents' association began to make an exchange with each other and their identity as residents enhanced, which means there was a change in the sense of community. Moreover, it is thought that a good solution to maintaining the chance for the events and exchange meetings after the support project is that residents of the younger generation actively cooperate in management as the residents' association members. 5 years after the support project, the present condition of activities of complex residents was examined, but the Residents' Association was disbanded due to the aging of residents, a growth in residents and low participation rates of the younger generation. Besides, there is a complete absence of community activities in the complex now.

The purpose of the city planning is to share the future image of the area where all citizens sympathize and to function as tools to implement a policy. Recently, the city of Seoul has established the community plan to manage the city as neighborhood units, but there are several issues that need to be addressed, such as lack of practical strategies. Therefore, this study studied the neighborhood unit plan in terms of feasibility. The comparative analysis is the masterplan of the City of Seattle in the U.S and the city of Yokohama in Japan, which are known to accomplish advanced urban planning. As a result, three factors were needed; there are 1) a masterplan that acts as an action plan, 2) administrative support tools such as financial and human resources that encourage people to participate in urban planning with enthusiasm, and 3) a management system that continuously manages the plan itself. This result is expected to be a reference for the establishment of method for the implementation of neighborhood unit plan in Seoul.

Various researches on the application of polymer dispersions to the cement mortar and concrete have been carried out in many countries like America, Japan and Germany and so on due to their high performance and good modification effect. PAE of polymer dispersion widely used in situ was employed that the high flowability may be induced in the cement mortar. In order to investigate the modification of cement mortar with high flowability by PAE and fracture mode of adhesive strength properties in tension of that, experimental parameters were set as PAE solid-cement ratio(P/C) and cement: fine aggregate(C:F) and the experiments such as unit weight, flow, consistency change, crack resistance and segregation that inform on the general properties have been done. Adhesion in tension is measured with a view to comprehending the properties and fracture mode in tensile load. Consistency change of cement mortar modified by PAE did grow better as the ratio of PAE solid-cement increased and was much superior to that of resin based flooring such as polyurethane and epoxy which recorded the loss of consistency in 90 min. after mixing. Adhesive strength in tension increased with continuity during curing period and showed the maximum in case of C:F=1:1 and P/C=20%.

Healthcare facilities design in Korea actually has begun from the late 1960s and early 70s and accomplished unprecedented growth qualitatively and quantitatively. In the 1970s and the 80s, domestic healthcare design was greatly influenced by the Japanese. In the 1990s, under the competitive healthcare-market environment, great concerns were dominated to american healthcare facilities than the Japanese which have comparatively monotonous architectural forms. In the meantime, domestic healthcare architecture firms have continuously learned about design know-hows of the US, Japan and eve European countries. Now I would like to evaluate the they are stepping onto in level that can equally compete with the advanced foreign architectural design companies. This study, investigating and consolidating architects' ideas and contents which experienced in design processes of real projects in current healthcare field, is purposed to find characteristics in design work of healthcare facilities and share the experiences. Method of research executed questionnaires to 22 special designers who design each 20 healthcare facilities. Questionnaire attained form July to October, 2008. Hereafter, it is going to present adjusting design process for healthcare facilities by analyzing various debris that is made in the process with design results that is made through design process.

Today the supply of school sports halls for multi-functional use is absolutely insufficient in school facilities of Korea. For economical reasons and efficiency of use, a joint utilization of these halls by schools, sports clubs and other users should be strived for. This will lead, as a result, to a minimization overall in the demand for halls. Above all to satisfy this demand, the regulations of sports facilities suitable to the students' standards of play and physical conditions must be preceded in Korea. And a study on the architectural planning of this hall size for primary, middle and high school is needed. This study aims at establishing the range of optimum size of school sports hall in Korea by surveying and analyzing the regulations of sports facilities about clear height of hall, obstacle-free zone and court area in Japan, England, Germany and U.S.A. Therefore, this study will offer valuable basic data in planning the school sports hall.

It is a well-known fact that most of the Korean school buildings has been adjusted by the standard plan according to the united and unified teaching method ever since the modern education started. However, seeing the recent growth of care for the open education, the effort to improve the teaching method in school fileds, the practice of the 6th education plan and the education reformation, it can be said that it is high time to change. As the number of schools which practice the open education has been increasing since in 1985 in this atmosphere, there have also appeared elementary schools with the open school building. But the general understanding of the school building and the open space is not enough. Therefore, this study aims to analyze the general spacial conditions, such as the fresh and diverse types of learning method and their development and the concept of the open space along with its types, application, size, and constition by studying, from the standpoint of the building plan, the elimentary schools of a new type in Japan which adopted the open space 20years earlier than in Korean. This study can offer helpful suggestions as to the Korean school building because our situation is very similar to the early stage where the open space is adopted to the school building.
