Procurement system of public construction projects in Japan is changing with diversity in rapid pace. The quality assurance and risk management of construction projects should be more certain as the projects are turning into larger scale and more complexed. The clients in the public sector will want to make the relation of responsibility among the client, the designer (architects and engineers), and contractor clearer in terms of role and risk. Public-Private Partnership (PPP) is one of the methods for collaboration of the public sector and the private sector in public construction projects where the public utilizes the ability and suggestion of the private. Private Finance Initiative (PFI), Design-Build-Operate (DBO), market testing, designated manager system, outsourcing of tasks in local governments are well-known as examples of PPP in Japan. Indeed, there is an obvious trend that Design-Build (DB) is adopted in public construction projects in many countries including Japan. In this paper, the public construction projects in various procurement systems are surveyed and analyzed. They are not limited within the traditional procurement, Design-bid-Build, a separate order system of design and construction. Design-Build or PFI are adopted. In particular, contract by wide range including maintenance of equipment can be found. On the other hand, modification from originally typical PFI is taking place, such as concept design and project finance are removed from the roles and the tasks of the special purpose company (SPC) in PFI. Standard roles and tasks in a construction project are modeled in this paper.

Arata Isozaki is one of the Japan's most important contemporary architects with an international reputation and has designed notable buildings in Asia, Europe, and the United States. Arata Isozaki is not an architect simply explained by a single ism or style, he has dedicated himself to express all diversities implied in different periods and styles. With an avant-garde spirit and enthusiastic creativity, he has devoted all his efforts to bring these diversities and complexities into his own architectural works. The study was aimed to identify the key characteristics implied in his overall design concept. Through the analysis of his works, the key features underlined in his works were characterized by five key words, which are tradition, eclectic, metaphor, metabolism and proportion. These five characteristics have been well Presented in his works individually and sometimes as a whole. His unique combination among these key design concepts has been impressed by many other architects in worldwide.

This study aimed to present a reinforced concrete block system that reduces the flange thickness of the existing form block used in new buildings and optimizes the web form, and can thus capable of being used in the seismic retrofit of new and existing buildings. By conducting a compression test and finite element analysis based on the block and grouted concrete strength, it attempted to determine the compression capacity of the form block that can be used in new construction and seismic retrofit. As a result, the comparison of the strength equation from Architectural Institute of Japan to the prism compression test showed that the mortar coefficient of 0.55 was suitable instead of 0.75 recommended in the equation. The stress-strain relation of the block was proposed as a bi-linear model based on the compression test result of the single form block. Using the proposed model, finite element analysis was conducted on the prism specimens, and it was shown that the proposed model predicted the compression behavior of the form block appropriately.

The goal of this study is to compare the evaluation results of indoor daylight environment for each certification and propose improvement points. As the importance of indoor daylight environment has increased, foreign countries have been aware of this and have changed the light environmental certification items. On the other hand, Korea environmental certification systems have not been able to follow the current situation. In order to improve this, this study intended to find evaluation criteria for each category by comparing and analyzing indoor daylight environment certification items in Korea's G-SEED, LEED in the United States, BREEAM in the UK, and CASBEE in Japan. After that, this study simulated 3D models of three spaces about classroom, reading room and club room of Yanghyun elementary School which is scheduled to be constructed for the evaluation of indoor daylight environment, and the results were analyzed to suggest for improvement.

The demand for long-term care is continuously on the rise as number of elders among the population increases. Due to the rapid growing demand for long-term care in Korea, there have been discussions for the introduction of new long-term care system into Korean society. The purpose of this study in to analyze changes of elderly care facilities in Japan after the beginning of long-term care system in 2000. The functional and architectural changes of Japanese facilities were researched to be used as references for predicting changes in Korean facilities. In Japan, after the execution of long term care system, the alterative aspect of facilities is divided into some categories; in sum, the change of environment for long term care, the effort to spread specialized facilities in a whole community, and the tendency to complex a variety of function of facilities such as an facility for home care service, and the like.

People with disabilities are an important part of society. The world has a huge population of disabled people. Therefore, it is important to study the establishment and improvement of the disability welfare law. To carry forward the humanitarian spirit and develop the cause of the disabled is a signㄴ of social civilization. Improving the welfare system for the disabled is conducive to social progress. Disabled people have the same right to pursue a happy life as non-disabled people. Now, South Korea, China and Japan all have disability welfare laws. But the content of welfare law is not the same. China's welfare law for the disabled is also very detailed, but there are many problems. Such as education, medical care and so on. Therefore, through this study, to understand the perfect disabled persons' system in other countries, will play a positive role in the development of China's disabled persons' welfare law in the future. By comparing the welfare laws of the three countries, we can learn from each other and make progress. To contribute to the development of the cause of the disabled.

We study, in this paper, on the decorative design of the Treasure-architectural form for the Silla Buddhist reliquary and this research went through the observation on the Buddhist Reliquaries of the Song-Lim-Sa, the Eastern-Western three floor pagodas in the Kam-Eun-Sa, the three floor pagodas in the Bul-Guk-Sa and the reportedly discovered Nam-Won. The Buddhist reliquaries of these 5 Reliquaries, when compared with those of China and Japan in the same period, they worshiped the Buddhist reliquary as a Buddhist God itself and put them as a part of the architectural decoration, being installed in the construction forms. In the form and the composition of the architecture, we can see those having been designed with very detailed and brightly decorated form. The Buddhist reliquaries in the Song-Lim-Sa and Kam-Eun-Sa, the most important ones in this research, were in a royal palace shape having completely the altar part, interior space part, and the ceiling part, which inform us the whole structure of the architecture in details. In particular, for the case of Kam-Eun-Sa, the columns in the shape of bamboo trees, the expression of the gates, the terrace of double parts formed of word-shape Man, and the statue of a general with superhuman ability in the shrine explain us the description of the Gyun-Bo-Tap-Pum of Lotus Sutra. After all these researches, we conclude that the Buddhist reliquaries in form of the Treasure-architecture represented the architectural style of the same period as a form of industrial arts and we can see that they tried to use all of their highly skilled and talented methods to describe the Buddhist Pure Land.

Hayakawa Kunihiko introduced community space as an open space in Housing in Japan for the first time. We can find the continuity of his architectural intent from his three works (Atrium, Steps, Labyrinth) during the early period of his Housing buildings, In particular, from Labyrinth, his intent was expanded to cities through 'Urban Void', seeking communication and harmony. Accordingly, based on the architectural overview and a field survey of Labyrinth, an analysis was conducted using Space Syntax to investigate whether the space of an inner courtyard is being used as a community space for neighbors who pass through the courtyard and whether the courtyard plays the role of 'Urban Void' as intended by the architect. For this investigation, according to VGA, the courtyard showed the role of great visual connectivity and integration and facilitated connections to the center of the entire space. On the other hand, according to J-Graph, the access stairway connected to each household from the courtyard helped secure privacy in the midst of common space. Step Depth noted that a hierarchy of space was formed to ensure visual privacy within each unit household in addition to privacy for each household.
