We live seeing, touching, or throwing on considerable textile in our life consciously and unconsciously. Since a Korean-style house is a dwelling space in life style of sitting on the floor with ondol(Korean floor heater), use of textile is limited to bedding goods. However, as western life style takes firm root, use of textile for interior design is increasing. As well, as apartments and foreign style houses have gotten lodgment since 1980, life style is being changed rapidly. So, textile became required factors in dining space where little textile existed. Through literature, history of textile is considered and design image concept is created based on the consideration. In addition, the created concept can be applied to various textile design, which can be a good tool to express eating culture of the country as well as the country's image.

The purpose of this study was to identify kitchen and non-kitchen use of space for cooking and dining. Three rural villages, Kum-sung Ri, Young-san 1 Ri, and Yu-bang 2 and 5 Ri were selected for this study. Present and past use of space for cooking and dining was investigated by the field survey method. The major findings were that : 1) Both the kitchen and other space such as the outdoor courtyard(madang) were the space for cooking. 2) Dining activities took place in ondol rooms, the wooden floor room(maru), outdoor court yard(madang) and kitchen. In the winter eating activities took place in the kitchen where heating is provided. Many village people ate at a Western style or at a Korean style dining table(papsnag) in the kitchen. 3) Compared with study I, the present research found similar use of space for cooking and eating, with slight differences in space for eating.

This paper presents that in the Korean Ondol Heating System using hard coal as an usual fuel, what effects an insulation of chimney with the low temperature gas flow has on the optimum chimney height which gives a maximum gas weight flow rate under the general weather data and actual design condition of chimney is compared with the bared chimney and studied. And also, the effects of chimney materials and diameter, dimensionless temperature difference, insulating materials and thickness which have on the optimum chimney height were researched and a good results increasing a maximum gas weight flowrate is obtained by insulating the chimney.

This paper is a part of "The Study of the Traditional Korean Ethnic Farmhousing in Yanbian, China". The purpose of this study focuses on Korean farm house and is twofold: 1) to survey the working space and storage space for tools: 2) to investigate the daily use of space according to the different work activities. It is based on a survey of 124 households in the farm villages of Lunching, China. Survey research methods included a field study in Dallajae. A questionnaire was used to conduct this study. the study found that the working space for the koran farm family is divided into an indoor area and outdoor area. The indoor space includes working areas where the families live their daily life, cook, launder, clean, mange the house keeping, usually stare the grain. The outdoor space includes areas to store the grain, farm tools, rice box, shelves and other things such as sewing machine, iron, and tools used for cleaning the house and for farming. The center of life and work for the farm family was the chung-ji-kan (the combined kitchen and major ondol living room) located in the indoor space.oor space.

This study investigated the Present traditional Korean farmhousing and Past housing (from 1928~1956) based on a survey of 23 Korean women from Kyongki Province. It was primarily concerned with a Comparison of the present and past housing ; the size and plan of the house and finishing materials of Anbang(The masters bedroom : ondol) and the kind of furniture. lighting and heating in the Anbang. I was also interested in identifying the socio-demographic and physical variables that influenced the housing, past and Present. Bibliographical studios. cultural approaches and field surveys with tape recordings and questionnaires were used to collect the data. The results showed that the former Housing(averag ; 54 years ago) was very poor. Most homes lacked sufficient space. furniture and experienced a shortage of fuel. The most decisive difference from the present was the large family size. It would be beneficial to make a similar study in both the southern and northern regions of Korea.

In this paper, we compared the thermal environment in the livingroom with panel heating system of Korea and Japan. The houses are two apartments and two single houses in Korea, and two apartments in Japan. The outdoor temperatures, indoor air temperatures, surface temperatures on floor and humidities were measured. The survey to the residents and recording of operation were also collected. The results were as follows.1. The Korean houses are warmer and drier(approximately 23$^{\circ}$C, 38%) than those of Japan.(approximately 20$^{\circ}$C, 57%). And indoor temperaures of Korean apartment are stabie. 2.The residents in Japan put on and off the switches of the heating system frequently.

기저부하조성 및 부하율 향상을 위한 심야전력요금제도의 정착으로 최근 심야전력축열기기의 보급이 활성화되고 있다. 그러나 모든 심야전력축열기기들이 심야요금개시시간대인 2f시경에 동시에 가동됨에 따라 23시경에 심야전력 부하가 최대에 이르러 전력피크가 발생하여 한전의 수요관리에 큰 어려움을 주고 있다 따라서 이 피크 부하를 심야전력 공급시간대의 저 부하시간대로 분산시킬 수 있는 심야전력기기 공급시간을 제어하는 통전제어장치가 필요하게 되었으며, 이미 축열식전기보일러와 축열식전기온수기에는 개발 보급되고 있는 실정이다. 이 논문에서는 다른 심야전력축열기기와는 달리 자연방열의 바닥축열난방방식인 축열식전기온돌의 통전제어장치 알고리즘을 실증실험을 통해서 검증하였다.

본 연구에서는 전기온돌의 안방열손실을 감소시키고 축열효과를 향상시키기 위한 방법을 검토하였으며 전기온돌에서 발생하는 진동소음을 감살시킬 수 있는 대책을 제시하였다. 저육들은 6.6[m$^{2}$] 크기의 전기온돌 model을 이용하여 건물의 구조차이와 하향열단열층의 설치유무에 따른 보온특성의 차이를 기록분석하였으며 그 결과 열전도계수가 0.03[kcal/m.hr.deg. C]정도인 내열성 Styropol과 지석 Mortar로 구성된 하향열단열층을 전기온돌의 마닥에 설치할 경우 난방부하의 감소로 인하여 축열효율이 약 2배나 향상된다는 결론을 얻었다. 또한 전기온돌공사시에 발열선을 지지할 수 있는 대각선형 Spacer를 설치하고 발열선이 매설콘크리트가 완전히 양생된 이후에 전력을 인가하면 흔히 전기온돌에서 발생하는 120-960[Hz]의 가청진동소음을 방지할 수 있다는 사실을 실험적으로 확인하였다.

This study was investigated with the surface properties such as physical and accelerated tests of wood-based floorings. In physical test, hardness and abrasion resistance values of laminate floorings were higher than those of others. The center line average surface roughness($R_a$) of imported laminate flooring was highest value($1.34{\mu}m$) and that of imported solid wood flooring was lowest value($0.62{\mu}m$). In cold resistance and moist heat resistance, no defects were found on the surface of all flooring (crack, blistering, peeling, and gloss loss etc.) after testing. Wet-cold-dry cycle test showed that plywood flooring appeared some cracks. In accelerated weathering test, color difference increased with increasing Xenon arc light irradiation

This study is investigated numerically on the heat transfer characteristics of surface radiation-natural convection interactions in a two dimensional enclosure assumed Ondol cavity. Mean Nusselt number of the bottom surface with surface radiation is increased by increasing wall emissivity and by decreasing dimensionless thickness of adiabatic wall. and is greater than that without radiation. Mean Nusselt number of the bottom surface for convection only with surface radiation is slightly smaller than that without surface radiation with decrease dimensionless thickness of adiabatic wall.
