Recent new town construction project proouced large numbers of apartment houses using precast concrete (P. C.) panels. l'bst construction companies involved in this project put their management focus on to the individual control of P.C. panel producing plants and the job sites. Little attention was paid to the integrated management of the production. transportation. and im;tallation of P. C. panels. Numerous job site delays experienced in the new town project were largely based on the poor coordination between these three key disciplines of the P. C. apartment construction. This stlldy was initiated with an .intention to improve coordination between these disciplines. Activities of these disciplines were identified and related data were gathered. This was performed through the interv:iews with the personnel involved in P. C. constructlon and through the analy::;is of the related documents and publications. Based on this information. the authors are nolol developing a model IoIhich will provide a foundation for opt:iJnal.ly coorc.inated control of the proouction. transportation, and installation of P. C. panels for apartment construction. In this paper. the authors briefly present intermediate results of this study.

This research explores about the construction process and provision of Japanese Wooden Houses. Even though Prefabricated Houses appeared during the 1960's and the Platform Construction System during the 1970's, there was still a high demand for Conventional Wooden House, with a high demand by households on their 30's. These features were found in the areas of Hokkaido, Kyushu, Tokyo, and Osaka. Tokyo and capital region accommodate large number of the head offices of companies that produce Platform Construction System houses, and thus supply the largest amount of Platform Construction System houses. In capital region, land prices are so high, that they build houses as 3-Floors or above, and also driven by high cost of house construction, house performances are excellent. The houses of Osaka and Kinki region demonstrate similar characteristics to those of capital region. Osaka is headquartered by a group of head offices of companies that produce prefabricated houses, and thus holds more amount of prefabricated house supply than other regions. This city also shows high cost of house construction no less than capital region, and thus offers outstanding performance of house. In Kyushu, whereas Japanese wooden house building systems are supplied the most, Platform Construction System houses are provided the least in the nation. As this region offers rich amount of forest resources owing to mild humid climate which is ideal for vegetations, the Japanese wooden building systems use the timbers from this region. Hokkaido, a cold region, requires houses that offer outstanding performance of heat insulation. Therefore, Hokkaido shows more supplies of Platform Construction System houses that offers outstanding heat insulation performance. They import the timbers that form the structure framework of Platform Construction System houses from North America.

In the modem society of Japan, specially before and after the World War II, one of the most important problem is socially to build housing of working classes. In those days, Ken Ichiura had been led the dwelling of modem Japanese architecture. He had worked in wide spheres of action like private residence, public housing, collective housing area and urban planning for about fifty years. But until now, because studies on public housing of Japan has been discussed only aspect of architectural design, there was almost no study about Ken Ichiura who acted in practical affairs. So this study aims to consider about the Ken Ichiura's research on dwelling and the relation with the then social circumstance. It was summarized as four details of Ken Ichiura's activities on Dwellings before the end of World War II. First, he proposed half-government-supervised system by economic reason on provision of dwellings. Second, he proposed dry construction system by material and structural reason on economic and stability supply. Third, he proposed standardization and industrialization by economic reason on industrialization form material to construction of industry. And the last, he also proposed standard plan and standard design by economical and mass production supply dwellings during the war.

Since 1939, Bupeyong was rapidly urbanized and industrialized for the purpose of constructing military logistics base of the empire of Japan. Based on Kyungin urban planning of 1940 and industrial land development plan of Kyeonggido, many military factories and arsenal were constructed, and great amount of housing were also built for their workers from 1939 to 1944. Although the initial urban planning was unfinished, urban change from rural area to military industrial city in the late Japanese colonial era, made identity of city of Bupyeong. Workers houses which built during five years vary in different size and type, and somewhat reflects discussions about housing attempts to solve the housing shortage. This study aims to analyze architectural characteristics of workers housing related with discussions of housing, and to evaluate its value as an industrial heritage which constitute the urban landscape of the industrial city of Bupyeong. Workers houses in Bupyeong were constructed by military factories, construction company, and Chosun housing administration, with land readjustment planning. As the war became serious, workers housing became smaller and simpler. Construction of workers housing was essential part of modern military industrial city, bupyeong, and many of workers housing are still remained whereas most of factories were demolished, thus workers housing of bupyeong has significant meaning as industrial heritage of Bupyeong.

In recent years, space planning ability using 3D sketch software is required in the working field of interior design. However, vocational high school do not respond appropriately to changes in the industry, because the class of vocational high school consists of hands-on practical classes and 2D CAD based classes. There is a shortage of 3D sketch software-based instruction programs that can improve students' spatial planning skills. Therefore, this study is to develop instruction program using 3D sketch software for 'Planning for Residential Space' unit of NCS-based on interior design subject and to find out the effect on students' academic achievement by applying to vocational high school class. The 3d sketch software based instructional program developed in this study was developed through four stages of preparation, development, implementation and evaluation according to the PDIE model process. The experimental design model used nonequivalent group posttest-only design in this study. Experiments were conducted on vocational high school students in construction and 9 hours of interior design subjects were applied. After the experiments, students were tested for academic achievement in the cognitive, affective, and psychomotor areas. As a result, the instruction program using the 3d sketch program developed in this study was found to be more effective in improving students' academic achievement than existing manual instruction program in both cognitive, affective, and psychomotor areas.

The purpose of this study is to analyze the distribution of the building area and find the characteristics of development density where the areas to perform special functions as residential, commercial, and business area in Seoul. As a result of classification of the regions with the component ratio of building area ratio by types, the greater part of Seoul is residential areas and only a small part of Seoul have business function. Contrary to the Kang-Nam business districts, the central business districts have few or no houses. It is concerned that the redevelopment projects, such as New-Town, make Seoul more high- density. The industrial area lost the attractiveness as a resident in spite of businesses or infrastructures. So the industrial area will be the best place for reduce journey-to-work distance if improve housing conditions. As well as management of density, management of use is also required for effective landuse and green-growth city.
