Each ethnic group has a different cultural background and has developed its own culture in the name of a tradition. The interaction between different cultures is ever increasing through the process of acculturation or culture contact The purpose of this study is to provide baseline information about domestic living of Korean immigrants in Australia and Australians for a larger cross-cultural study project. As the first step, the usage of domestic space and seating styles of 52 Korean households in Melbourne were analyzed. Ethnographic research was conducted, utilizing a questionnaire. The findings of this research are as follows: 1. The most popular type of Living-Dining-Kitchen arrangement was the one which the kitchen is separated from the living and dining area. The level of satisfaction was the highest when the living room, dining room, and kitchen were all separated. 2. A laundry room was indispensable for Koreans in Australia, and they wanted to dry laundry and do ironing in there. Most people were satisfied with the toilet separated from the bathroom A drain hole on the floor of the bathroom was not indispensable for most Korean-Australians. 3. Korean-Australians tend to engage in various activities in their individual rooms, and they estimated that the size of most rooms were small. They also wanted to renovate the house to expand the rooms. 4. The seating style of Korean-Australians was mostly chair-seating. Yet, they often made beds on the floor for guests, and made kimchi sitting on the floor. Also, when they were relaxing, they were using both chair-seating and floor-seating. 5. Korean-Australians were not very satisfied with the use of floor carpets because of the dust collected on the carpets, and the difficulty to clean. It may be related to their preferred floor seating style, as well. 6. Almost all Korean-Australians take off their shoes inside of the house for hygienic reasons. They had a shoes cabinet at the entrance inside of the house. 7. The most popular heating system was ducted heating. The level of satisfaction about this was moderate because hot air contains lots of dust and it makes rooms very dry. Many were using electric blankets and their desired heating system was Ondol (heated floor). 8. Korean-Australians thought that the living room was the most important place for the family, and believed it should be decorated well to entertain guests. They also pointed out that the lighting was not bright enough in general.

In this paper, we investigated quality properties for the expansive of the CaO-$CaSO_4$ family which used to compensate dry-shrinkage in the floor mortar of On-Dol heating System. This experimental study established the mix condition with quantity of the expansive and is to investigate the relativity between the compress strength and the length change and the relativity between the chemical properties and the length change with the analysis of the physical and chemical properties. As a result of the study, the expansive is controlled by more the CaO than the $CaSO_4$. The relativity between the compress strength and the length change is expressed by exponential function, showing that if the expansive performance is increased, the compress strength is decreased. And the relativity between the chemical properties and the length change is only relative the quantity of the F-CaO among the chemical properties, is expressed by the second order function, showing that if the F-CaO is increased, the expansive performance is increased.

The objective of this paper is to clarify the combined effect of heat conduction, air temperature and thermal radiation on the person seated on the floor under operation of floor heating system. Experiments were conducted for summer seasons under 8 kinds of condition: combinations of air temperature $20^{\circ}C$, $22.5^{\circ}C$ and floor temperature $20^{\circ}C$, $22.5^{\circ}C$, $30^{\circ}C$, $35^{\circ}C$ and $40^{\circ}C$ under still air. Japanese and Koreans were adopted as subjects. To evaluate the effect of conduction operative temperature modified by heat conduction was derived from the human heat balance equation. New weighting coefficients were estimated from the modified operative temperature and modified mean skin temperature. As for thermal sensation the modified operative temperature more significantly correlated to that sensation each heat transfer processes. As the floor temperature is higher, the human conduction heat gain from floor increase and the dry heat from the human body decrease.

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 interaction between different cultures is getting more active through acculturation and cultural contacts. The purpose of this study was to compare domestic living of Korean immigrants with Australians in the form of a Cross-Cultural study. For this, usage of domestic space and seating style of 52 Korean households and 53 Australian households in Melbourne were analyzed. Ethnographic research with questionnaire was used. The results of the research were as follows. 1. The most popular type of Living-Dining-Kitchen arrangement was L+ K. D for Koreans and L. D . K for Australians. 2. A laundry room was indispensable for both and they all wanted to do ironing in there as well as dry. Both were satisfied with the type which toilet was separated from the bathroom Drain hole on the floor of the bathroom was not indispensable for most Koreans and Australians. 3. Koreans and Australians were doing various activities in living area and both were getting together around kitchen(dining) area. The particular thing of Koreans was that they were using the main bedroom with multiple purpose. 4. The seating style of Koreans and Australians belong to chair-seating style generally. But Koreans were using floor seating style in making bed for the guest and making Kimchi. Koreans and Australians were using mixed style of floor seating and chair-seating in relaxing time with watching TV, treating guest or so. 5. Koreans were not satisfied with using carpet cause of dust but Australians were satisfied with the carpet cause of warmness. 6. Most Koreans and Australians were take off shoes inside of the house. Koreans were organize shoes around the front door of the house usually and Australians were organize shoes in bedroom usually. 7. The most popular heating system was ducted heating for both. The level of satisfaction about ducted heating was low for Koreans because they though that it could contaminate air. Australians were satisfied with ducted heating because they though that this one was fit on the weather of this area. 8. Living room was the most important one for Koreans and Australians and they also thought it should be decorated well for entertaining guests. Most Koreans were estimate that the brightness of the light of the house was not enough but it was estimated to moderate for Australians on the contrary.
