The purpose of this study is to provide data for planning future temporary housing in Korea by comparing and analyzing the characteristics of emergency housing rapidly supplied by Japan Prefabricated Construction Suppliers and Manufacturers Association(JPA) and general construction companies, according to the supply subject in times of natural disasters in Japan. Literature reviews and on-site field investigations are conducted as research methods during the period of August 4th~9th, 2019. As subjects of study, the characteristics of two housing complex built in Ishinomaki City with different supply subjects were compared and analyzed. As a result of this study, Japan has a clear distinction of terms for emergency housing, which are divided into rental and construction types. With the close cooperation between the government, local governments and construction companies, providing a prompt systematic supply is possible. The characteristics of emergency housing are differ depending on supply subjects. The emergency housing of JPA has diversity of plane, two rooms facing south, and fast construction time, while the emergency housing of the general construction company has a flexible spatial transformation and excellence of materials.

The thesis is a comparative analysis of Infill Technologies between Korea's long-life Mock-up House, a study driven by 'Durability and Flexibility of Long-life Housing Technology Development' of R&D, and Japan's KSI experimental house, the major example of Japan's long-llfe housing. In terms of the domestic Mock-up House, a system of building the floor first was applied. The floor material of each housing unit required a development of dry heating component that is partially substitutable in order to avoid conflict with the finishing. Also, a development of a floor system that can counteract against the construction inaccuracy was required. In the Case of an outer wall, need to make the wall with the chassis. In the case of ceiling, need to develop the double ceiling system which is good for sound insulation. Also, in comparison to KSI experimental house in Japan, it would require to develop a wiring system of the ceiling which can react to the movement of the wall. Especially, to assure the flexible nature of an internal wall, it would desperately require the research and development of the products related to components and flexible system of mechanical/electrical/communication parts as well as supporting institutionalized system for this development. Furthermore, for KSI experimental house in Japan, it would be necessary to formulate a construction manual as well as a systematic and practical planning guide to invent a new interface rule which will secure simplicity of assembling, dismantling, installation and replacement of architectural components for which research development is quite insignificant at the moment. This effort will have to continue to give a solid direction for better application of such reference manual during construction and development of long life span apartment by public sector as well as private corporations.

The objective of this study is to find a possible application of small space utilization of GangSo Housing, so called compact-but-effective housing, through analyzing that of Japanese small housing. We analyze openness of view and flexibility of spaces divided by the physical and architectural aspects as first component and the psychological and interior space aspects as second component. The results showed that Japanese small houses have various unit plan compared to uniformity of Korean houses. Openness of view in Japanese small housing is accomplished by letting in light from the outside using position and shape of the window, looking more spacious using courtyard, void spaces, or sliding door hanging from the ceiling, and creating deception of view using floor-wall plan and appropriate materials. Flexibility of spaces is achieved by combination of first and second components, multipurpose of space and furniture, and variety of storage methods. It is necessary to improve spatial efficiency with consideration of volume-metric planing rather than flat-plane and develop various unit plans to meet residents' needs and demands on compact-but-effective houses.

This study was intended to grasp the housing unit plan which the residents preferred. The subjects were 100 housewives who lived in 85$m^2$ sized housing units in the New Apartment Complex, Gimhae. First, four elements of unit plan were selected on the basis of the results of the POE which was carried out for the same subject the size of master bedroom and living room, the openness of dining/kitchen from living room, the openness of living room from entrance, and whether or not a bathtub or a shower booth is in bathroom. Then, eight design alternatives of unit plan made by combination of these four elements according to orthoplan were visualized by computer media. This visualized tool was used for collecting data. The results of the study were as follows: The important determinants of the residents' preferences for unit plan were the size of master bedroom and living room and the openness of living room from entrance. The residents preferred the unit plan which living room was large and the view from living room to dining/kitchen was open. Also, the important elements were different according to the characteristics of the residents. Therefore, the housing alternatives which are flexible and optional would be desirable.

The free vibration of a spinning flexible disk-spindle system supported by hydro dynamic bearings (HDB) in an HDD is analyzed by FEM. The spinning flexible disk is described using Kirchhoff plate theory and von Karman non-linear strain, and its rigid body motion is also considered. It is discretized by annular sector element. The rotating spindle which includes the clamp, hub, permanent magnet and yoke, is modeled by Timoshenko beam including the gyroscopic effect. The flexible supporting structure with a complex shape which includes stator core, housing, base plate, sleeve and thrust pad is modeled by using a 4-node tetrahedron element with rotational degrees of freedom to satisfy the geometric compatibility. The dynamic coefficients of HDB are calculated from the HDB analysis program, which solves the perturbed Reynolds equation using FEM. Introducing the virtual nodes and the rigid link constraints defined in the center of HDB, beam elements of the shaft are connected to the solid elements of the sleeve and thrust pad through the spring and damper element. The global matrix equation obtained by assembling the finite element equations of each substructure is transformed to the state-space matrix-vector equation, and the associated eigen value problem is solved by using the restarted Arnoldi iteration method. The validity of this research is verified by comparing the numerical results of the natural frequencies with the experimental ones. Also the effect of supporting structures to the natural modes of the total HDD system is rigorously analyzed.

This study is on the spacial flexbility of house. In the recent days, it is true that the qualitative aspect of residence rather than the quantitative one has emphasized. But the inhabitants of residence undergo adaptation problems to deal with changing needs constantly. Residence must be the place to satisfy inhabitant's desire to live and dwell. According to changes in family life cylce and personal demand, the flexibility in housing should be beneficial. This study attempts to solve relationships of these need changes and inhabitant's adaptation through the spatial flexibility. Throughout the process of main discourse, some theoretical backgrounds of housing are applied. And to introduce the flexibility of residential space, concepts of flexibility according to 'time' and 'spatial structure' are employed. In addition to functionality and comfort, living should provide a touch of humanity attuned to individual sensibilities. The purpose of this study is to suggest a method can move interior structure by the flexible planning.
