The shape of the roof is very important, as it determines the beauty of the exterior of Korean wooden architecture. In particular, the curve of the eaves is the most representative of the characteristics of Korean wooden architecture. Rafters and buyeon (浮椽), flying rafters, create curves for the eaves, and buyeon in particular makes the roof lighter and more dynamic. Although the function and role of buyeon are already known, nothing is yet clear about the beginning of its use in Korean ancient architecture. Accordingly, the purpose of this study is to determine when buyeon was first used in Korean architecture. To this end, I examined various records, buildings, remains, and artifacts that have architectural shapes in Korea, China, and Japan. The results are summarized as follows. First, the use of buyeon in China appears during the Northern Qi Dynasty (北齊) in the mid-6th century, but became common in the 7th century during the Tang (唐) Dynasty. Second, the use buyeon in Japan appears in the mid-8th century, when the capital was relocated from Asuka (飛鳥) to Nara (奈良). It corresponds with the time that Japan began importing Chinese culture directly. Third, the use of buyeon in Korea may have been introduced to Baekje from China in the mid-6th century, but it was not common. It is believed that it became common after active exchanges with the Tang Dynasty during the Unified Silla Period in the mid-7th century.

A technical analysis was conducted to predict the development trends for heat pump system. This study was based on submitted patents from 1983 to 2002 in Korea, USA, and Japan. The total number of raw data from the registered database was 19,261 and the obtained data to be analyzed through the filtering process was 5,143. Japan's technical development for the heat pump system was more dominant than the other countries. Approximately $54\%$ of the total patents related with the heat pump system was registered by Japan. The number of patents for the heat pump system registered by Korea was very low in 1980's, but it increased rapidly in 1990's. As a result, the number of patents applied by Korea was $21\%$ of all patents. When the patent was categorized into compression, absorption/ad-sorption, and chemical type, the technology of compression type made up over $80\%$ in each country. Approximately $93\%$ of the patents surveyed in this study was developed for air or water source heat pumps because of easy applications compared with other heat sources. The $89\%$ of all patents was applied by companies when applicants were divided into three groups of company, individual, and the others (national institute, university, and so on).

In this paper, the changes of the period of cold weather concrete in Korea with the elapse of age are discussed to investigate the influence of elapse of age on period of cold weather concrete. The climate data of Korean Meteorological Administration(KMA) ranging from 1971 to 2000 was used. The period of cold weather concrete was calculated by following the specification of Korea Concrete Institute(KCI), American Concrete Institute(ACI) and Architectural Institute of Japan(AIJ), respectively. Previous research by the authors used the climate dada of KMA from 1961 to 1990 and research conducted by Kim M.H. used the climate data from 1931 to 1980 were also compared with the period of present paper. According to the results, in present paper, the period of cold weather concreting by KCI was calculated about 95days on average and the period by ACI was 101 days on average and the period by AIJI was 92days on average. For the variation of the period with the elapse of time, the period of cold weather concrete by KCI and ACI in present paper was shortened by as much as 5${\~}$6days compared with that of previous paper 10years ago. However, the period of cold weather concreting by AIJ did not exhibit a marked reduction in the period compared with that of previous paper by the author. But the period by Kim following AIJ exhibited a decrease in the period compared to the period by present paper by as much as 3days. For regional influence, the period of cold weather concreting in southern part of Korea was found to be much shorter than those at northern part. This may be due to the rising of mean temperature caused by global warming effect.

Mountains have been playing an important role in the Japanese culture. It is important from landscape planning perspectives to maintain mountains in the proximity of cities. In this thesis, the geographical perception of residents in Kohoku New Town has been studied. Geographical changes before and after the Kohoku New Town development were clarified first. Following these clarifications, interviews with residents who moved into the area before and after the development were conducted. In this investigation, the interviewees were asked about mountains, valleys, hills, and slopes; and the areas that they recognize on the map were then specified. From these results, the mountain area which residents recognize and the actual geographical features were compared. The geographical characteristics of the mountains that the residents recognize were revealed, and the perception of mountains was defined. Not only did geographical features and vegetation affect the perception of mountains, but also residents' personal experiences were important. As a result, new information for future geographical landscape planning has been obtained.

The Guebangjip(꿰방집) house in Gocheonri(고천리) is built of architectural materials which are not by composition but by penetrating the drilled materials as the meaning of its character. Comparing with other cases such as Japan and China which this kind of structure method is still generally used, it is hardly found any cases in Korea. However it could have been used in Korea because of the vestiges of Sogeo(巢居) and Gannan(干欄) style architecture. Apparently it is considered as the traditional building technology which is existed by succession in the certain range of time and space.

The purpose of this study is to comprehend how traditional design theory, 'design elements and principles' have been applied to space design, taking interior designs of restaurants as the subjects of the research. Furthermore, this study intends to provide practical help to the restaurant designers and students who major in interior design, by summarizing the applications case by case. For the analysis, 10 restaurant projects were selected to which 'design elements and principles' were well applied. In order to widen the scope of application cases, this study selected four Korean restaurant projects, and three US and Japan restaurant projects, respectively. Through the analysis, it was found that many unexpected results can be produced when various elements composing a space are combined together, including not only two-dimensional elements such as plane and color, texture, and pattern but also three-dimensional elements and architectural elements composing interior space. Moreover, I became to have confidence that 'design elements and principles' would sustain the value in most design parts including interior design in the future as well.

Partnering has taken root all over the world as a remedy for the adversarial relation between parties concerned with construction projects. It is deemed to be derived from Keiretsu in Japan where parties related cooperate with one another as a team gaining reputations for completing projects on schedule and budget while maintaining high standard of quality. However, Keiretsu is now being weakened in proportion to the economic recession and there is an important change that needs to happen in the industry. The aims of this study are to find out the essence of Keiretsu by comparing Keiretsu with Partnering and to look for the direction of the reform plan.

The average number of deaths in the construction industry reaches 500 per year, and in particular, it is confirmed that the type of accidents and deaths caused by disasters such as work platforms has occupied more than 60% of the total. In this study, we presented a structured and combined solution for technology, management, education, and cost that can solve systematically, politically, and external environmental factors as well as direct influence factors. In addition, we examined the safety and safety standards of domestic and international safety, and discussed implications. First, direct impact factors, organizational impact factors, policy influence factors, and external environmental impact factors were examined and classified into technical, education, and institutional dimensions. Second, in relation to the installation of the work scaffold, the standards (OSHA 1926.452), UK (The Work at Height Regulations 2005 No.735, BS5975), Japan (Labor Safety and Sanitation Regulations) and Germany (DIN 4420_4, DIN EN12810). In the case of domestic safety standards, similar to the foreign safety standards, safety measures such as materials and specifications are applied. However, details related to the installation, assembly and structure of the work platform are somewhat different from those in the United States and the United Kingdom excluding Japan. Using the results of this study, it is possible to understand the cause of the accident of foot pedestrian accident more systematically and comprehensively, and safety managers and researchers are expected to help in the accident investigation.

An understanding of 'original form' plays an important role as it is the starting point of heritage conservation. This paper delineated several types of understanding on 'original form' over times, and aims at analyzing the way how such concepts has provided a platform of repair works of timber buildings in Korea over times. Conservation in Korea was initiated by the attitude of the Japanese authority during the Colonial period and 'restoring into the earliest form', which had been set in the early stage of the Japanese conservation, has strongly influenced on Korean practice during the period. Such attitude has lasted even after the independence of Korea. In Japan, however, the attitude has shifted to taking a careful decision on the alteration of the existing form during the 1930s. In addition, examination and research in the repair work became essential steps to conduct along with the publication of the report of works. In Korea there has been lack of understanding on the importance of examination and research in repair works and the publication of report of the works has not been mandatory so that it has emphasized on the 'form' in conservation aiming at 'restoring the earliest form'. Such attitude has created the problem of replacing original material during the work which should aim at preserving and maintaining heritage in Korea. Because of these circumstances in preserving the architectural cultural properties in Korea, cultural buildings had succeeded in preserving the outer appearance but there are remaining questions on preserving the original states of them. This paper has pointed out that it is necessary to set out the principles of conserving 'original condition' through further study and discussion based on the careful consideration on both the international principles and Korean context.
