Since the apartment was built by Korea National Housing Cooperation in 1961, the amount of its supply has been increased greatly, especially from the late 70's. Recently there are many ongoing studies regarding sustainable construction apartment in Korea, one of the research is developing sustainable apartment that has longer life cycle. Also according as life's quality of residents is upgrading, complain for impact noise and plumbing system noise from upstair or downstair are increasing more and more. To solve this complains, government established impact noise standard as lightweight impact noise of 58dB, heavyweight impact noise of 50dB and presented standard floor system or recognition floor system to satisfy this impact noise standard. So in this study, the aim is to develop dry ondol access floor system for sustainable apartment which have pleasant and quiet life environment.

The principle of Korean Traditional Housing was to be harmonized with the nature with shapes according to regional climate and materials easily available from the region. These environmentally friendly characteristics protected indoor environment from climate changes. The characteristics of Korean traditional housing to control indoor environment would be very useful for contemporary housing in that current issues, improving housing amenity and wellbeing, had basic goals same with what Korean Traditional Housing had. Though it could be found characteristics of indoor thermal environment heated by Ondol Heating System, analyses of evaluation made by occupants of the rooms were insufficient because most of the studies had been focused on the measurement of indoor thermal factors. Thus, with an evaluation of occupants for the indoor thermal comfort and an estimation of discomfort derived from the result of vertical temperature distribution, it was studied whether the agreeable indoor range of rooms, of which was Jeonju Hanok Living Experience Center, heated by Ondol Heating System corresponded to the agreeable indoor range presented in references.

In this study, we compared a plain mortar with the CAS-system shrinkage compensation mortar for Ondol that is Korean traditional heating system. The Ondol mortar is necessary to have properties as non-crack, fine flatness and stability for thermal changes. especially, mortar'crack prevention is to be most important property in Ondol mortar. To develope the stable material on the crack-prevention, we used to calcium-sulfo-aluminate(CSA)system in shrinkage compensation mortar. And so, we confirmed the effects of calcium-sulfo-aluminate(CSA) system for mortar's physical properties such as setting time, compressive strength and expansion ratio for crack prevention. The initial and final setting time of the CSA mortar is faster than plain mortar about 2hours. And, Compressive strength increased about 20% that plain mortar. The crack length per unit area, plain mortar is 0.426∼0.481m/m2. The Results of apartment construction field test, the shrinkage compensation mortar is excellent about the crack-reduce effect.

The ondol is a uniquely Korean system of providing warmth to room. The ondol rooms never use daily life furniture because the ondol warms the floor surface where people sit. Finally, the ondol floor changed the traditional housings inner space. Before use ondol where daily life furnitures[sang(상) and Tap(탑)] are installed in the room. The origin of daily life furnitures are the ancient tomb mural of Koguryo Period. The daily life furniture can be classified as three large groups in the ancient tomb mural of Koguryo. First, a single seat[Jowa-sang(좌상)] of set up a screen[병풍]. The second, It make possible Many peoples take a seat with no decoration seat[Tap(탑)]. The third, uptodately table and chairs. A radical difference between sang(상) and Tap(탑) whether set up a screen[병풍]. The meaning of sang(상) and Tap(탑) in Koguryo ancient tomb provided Oksa-jo[옥사조] in Samkuk-sagi[삼국사기] with several valuable leads to help solve the sang(상)'s meaning. Furthermore, It will be start ponit of study on constructive shape of inner space in those days.

The objective of this study is to improve the control performance of Ondol system which causes overheating and underheating with 2-position on/off control. For this, a predictive control that determines the suitable on/off positions using Artificial Neural Network(ANN) model was proposed Dynamic analyses using computer simulation show that the neural network used in the predictive control is adapted to each room whose loads variation and thermal characteristics are different. To examine the applicability of this predictive control with ANN it was compared with 2-position on/off control through experiments.

The aim of this study is to discover thermal characteristics of Ondol heating systems. The housing subjected was categorized into detached single family houses and apartments, reinforced concrete and brick structures, intermittent and continous heating system, and the space subjected was bedroom. In order to understand the thermal characteristics of each floor heating systems, the vertical distribution of indoor temperature and the distribution of surface temperature on the floor were measured. The vertical distribution of indoor temperature except the measurement point 1 largely showed average temperature distribution, and the temperature of the measurement point 1 in the housing surveyed showed the highest temperature in the house "sample A" because of the radiation heating from the floor of the Ondol room. As the result of the measurement, the thermal characteristics of each heating system were more stable distribution in apartments of R.C structure.structure.

The purpose of this study is getting information for making a plan of immigrant workers in Korea. As a first step to suggest plans for immigrant workers who have multi-cultural background, this study investigated to the domestic living of Koreans(ChoSun-Tribe) of Gillim province in China. For this, usage of domestic space questionnaire were used. Results of the research were as follows. 1. The most popular LDK type was the one which kitchen was separated from living room and dining room. Most of them thought that kitchen and living room have to be separated. 2. There was no plan for laundry room specially and most houses have a washing machine in the bathroom. Most houses didn't install a bathtub in the bathroom and they didn't think that it was indispensable. 3. It was estimated that they used a living room as a multi-purpose room for the family but used a master bedroom for its own purpose. 4. They used a table and chair for meals normally but they took meals sitting on the floor with a large family or guest. 5.All of them took off the shoes inside of the house for hygienic reason. There was no plan for the space to take on-off shoes in most houses and they just put the mat on the floor for it. 6. Modified Ondol system which use water pipe under the floor was popular in apartment while most detached houses had traditional Ondol system. The satisfaction about Ondol system was very high compared to other ones and also Ondol system was the most desirable one for ChoSun-Tribe.

The traditional Korean heating system ondol, one of the most important characteristics of Korean architecture, still remains as hydronic floor heating. Various studies have been conducted on the modernization of ondol, but the process of introducing the hydronic floor heating has not been seriously studied so far. Therefore, this paper aims to demonstrate how the hydronic floor heating had been introduced to Korea, taking the 1950s and 1960s Haengchon, Jongam, and Mapo Apartments for example - these three are regarded as the first Korean apartment houses after the Korean War. While Western advanced construction technology was imported for these apartments, various methods of modernizing ondol were also considered. What was remarkable in these attempts is that hydronic floor heating first appeared in Mapo 1st Apartment in 1962, because this is the universal heating method in the present Korea. This fact signifies that the traditional principle of floor heating has been maintained, and it would also be meaningful in terms of architectural exchanges between East and West, if considered along with Wright's application of the Korean heating principle to his houses since 1930s.

This paper is to present the performance data for pressure setting method using some tile bonds for application on the Ondol-Heating floor system. For this purpose, powder and liquid tile bonds(Organic.Inorganic mixed tile bonds) were compared with the conventional tile cement for pressure setting method in the sight of the adhesive stability of porcelain tile. It tested for tiles after 14, 28days under standard condition and severe conditions. The severe conditions were water immersion and heat ageing($70^{\circ}C$). Another experimental factors concerned tile bond properties such as mixing ratio(in case of using liquid admixture), open time, which are supposed to affect the tensile strength of tile, were studied and discussed through the experiments.
