본 연구는 실내 온열환경에 대한 인간의 온냉감을 정밀하게 평가하기 위해 바닥난방이 실시되고 있는 겨울철 아파트의 거실에 대하여 공간내의 온도분포를 조사하는 동시에 신체부위별로 온냉감을 조사하였다. 실내의 온도분포 측정은 서울과 부산의 두 장소에서 실시하였으며, 온냉감에 대한 평가는 서울에서 남자 31명, 여자 71명, 부산에서 남자 11명, 여자 23명에 대하여 수행되었다. 결과는 중앙집중식 난방이 실시되고 있는 거실의 바닥으로부터 10cm높이와 170cm 높이에서의 온도차이는 서울의 아파트가 3.2 $^{\circ}C$, 부산의 아파트가 2.$0^{\circ}C$로 나타났다. 겨울철 실내의 온냉감 조사는 하루 3 회 실시되었으며, 신체의 3개부위에 대한 온냉감과 전체적인 온냉감이 7점 척도로 평가되었다. 결과는 발과 얼굴, 무릎과 얼굴, 발과 전신사이에 온냉감의 차이가 있는 것으로 나타났다. 발과 무릎 부위가 얼굴에 비하여 추운느낌을 강하게 가지며, 전체적인 온냉감은 얼굴부위에서의 평가와 유사한 수준을 나타냈다. 난방이 단순한 온도조절의 범위를 넘어 인체의 온열쾌적감을 만족시키기 위해서는 신체의 부위별로 느끼는 온냉감을 정밀하게 평가하여 난방의 방법을 조정하여야 하는데, 이 연구의 결과는 난방의 방법 결정에 기초자료로 활용될 수 있을 것이다.

The residence space has been in the trend of being expanded with the J'l'cent economic growth Therefore PAC may be said to have [wen from business use to home US(: the progressed living standard as the goods ior Uw "ummel' S('dSOn rest'ntly though sold in Uw fast for mainly buslTw"s use. PAC has been in the demand day ;lner day and in the tn'nd on the bc,ing the necessJty of the n'sent wf',lther warming phenomenon This study is the case study nf the products development and design process of PAC which has bpcn llrivcn and developed by Gold Star Co. ,Ltd. Which .is the firm for home electric appliances representing Korea. This studies for the development and the design of the products by the firm thus emphasizing the visulizing it based on this study. For example as they being the goods for the summer season I have tried to know the physical quakity and the characters of koreans by the weather conditions and estimated the demand by setting up the target customers of the PAC as the customers' environment. And I analyzed the acts in the living room in the apartments as the living envinorment which has the direct relation with PAC and also became a help to the moulding work of PAC by analyzing the complete interior image in the living room. In the practical moulding work the Design concept was classified into the envinorment of customer, living and products to drive as the below. Firstly - New shape (Round slim) has been realized which leads the minimizing the moulding space and visul sense of opening as its being spacious. The 2nd - the high class sense of the products which are harmonious with the atmosphere of the living room by making it interiorized has been visible. The 3rd - The shape stimulating the sensitivity of the users and surface treatment are emphasized by making it be touched. The 4th - During inviting use of technology image which appears in the electronics products are attemptedby making it be high quality.king it be high quality.

This research was aimed at finding clues of improving behavioral affordance of the residential environment by scrutinizing change of the residents' behavior in a livingroom depending on the child's development stage. 30 double-income families with one child were the subjects of depths interview, survey, observation of this research, who were residents of 3-bedroom apartment housing in Seoul. They presented obvious different behavioral patterns according to their child's development stage. Breeding and playing behavior were prior to the others when their child was in childhood, then relaxing with TV and PC behavior were getting superior when their child was in school period. It is important that residents perceive that the numerous types of behavior may take place in a livingroom, some of which has originated in our long residential culture. And then real housing should be provided to them that has proper behavioral affordance to support all those behavior. Housings with minimum walls and rooms would make it possible. A family has its inner dynamics can live a sustainable life in that housing as a home, that lasts along their whole life.

This research study was conducted to determine the actual conditions of living room lighting in Daegu and Gyeongbuk districts. For this study, 112 households were surveyed. The results of this study are as follows: Firstly, fluorescent light was used as the general illumination of living rooms, and the ratio of not using local sources of illumination was high. Secondly, the standard illuminance was found to be 221. The illuminance was the value that satisfied the activities for togetherness and entertainment, but did not reach the illuminance necessary for other activities, such as reading, make-up, and sewing. In addition, the uniformity of brightness used as a measure of uniformity in examining the results was normal. Thirdly, both the brightness and the satisfaction of lighting in the living room space were indicated to be normal. In addition, in regard to housing lighting, 'stability', and 'brightness of lighting' were indicated as important considerations and 'brightness of lighting', 'shadow' and 'management of lighting' were indicated as problem areas.

자연채광은 실내공간의 쾌적성을 향상시키며, 재실자의 건강을 증진시킬 뿐만 아니라 에너지 절약적인 측면에서 시너지 효과를 발휘하고 있다. 이에 반사거울형 태양광채광시스템은 도시가 과밀하고 고층화됨에 따라 자연채광의 도입이 어려운 실내공간에 태양광을 도입할 수 있는 자연에너지 활용장치라 할 수 있다. 본 연구는 태양광채광시스템을 이용하여 주거건물 옥상에 1차반사거울을 설치하고, 반지하의 상부에 2차반사거울을 설치하여 거실공간에 태양광을 유입하였다. 시스템 미설치시와 설치시에 대한 거실의 바닥면조도와 외부조도를 동시에 측정하여 외부조도에 대한 내부조도의 비율인 주광조도비를 분석하고, 증감율을 구하여 반사거울형 태양광채광시스템의 성능을 평가하였다. 채광성능평가 결과 채광시스템의 설치로 인한 실내 주광조도비는 평균 $80{\sim}1,400%$정도 증가하는 것으로 나타났으며, 또한 창면부에 비해 실의 후면부가 2배 이상 증가한 것으로 나타나 채광성능이 매우 큰 것으로 나타났다. 따라서 본 연구에서 실험한 반사거울형 태양광 채광시스템은 주거건물에서의 적용이 용이하고 높은 채광성능을 제공할 수 있어 실내 빛환경 향상에 크게 기여할 수 있을 것으로 기대된다.

As part of an air pollution epidemiological study of asthmatics residing in the Houston area, an air monitoring system provided data on the indoor and outdoor measurements of major pollutant gases sampled at selected residences during May ~ October 1981. Continuously monitored pollutant gases included sulfur dioxide ($SO_2$), nitrogen dioxide($NO_2$), nitric oxide(NO), carbon monoxide(CO), and ozone($O_3$). Outdoor levels for each pollutant were compared with their indoor levels(bedroom, kitchen, living room). Mean concentrations of each pollutant in the kitchen, and living room exceeded the mean levels outside except for ozone, while average bedroom levels for all gases except for $O_3$ and $NO_2$ were found higher than the corresponding outside levels. Indoor/ outdoor ratios for $SO_2$, NO, and CO were 1.8 ~ 2.7 times the outdoor levels, but indoor/ outdoor ratios for $NO_2$ and $O_3$ were 0.99 and 0.06, respectively. The impact of several important household characteristics (type of cooking fuel and cigarette smoking) on the indoor levels for these gases is evaluated.

As the consumer market for odor products grows, companies producing healthcare products are beginning to pay more attention to the emotional aspect of an odor product in order to differentiate their products from competitors. In the following research, the affective effect of odor product was investigated while focusing on relaxation and working contexts using orange and pine scents, since these are typical odors in current domestic market. Two empirical studies were carried out. First, in experiment I, 18 subjects, all of whom were university students, spent 20 minutes sitting comfortably on a sofa while electrocardiogram assessments were made. After a five-minute break, in experiment II, the same subjects were provided with both arithmetic and geometric questions and their electroencephalogram readings was recorded from eight channels. All subjects participated in three sessions - no odor, an orange scent, and then a pine scent - with a minimum time interval of 24 hours. The results show that in the context of a pine scent, both the activation ratio of subjects' parasympathetic system and those of the Sensory Motor Rhythm waves and Mid Beta waves were at the highest peak. Therefore, the pine scent helped the subjects to feel more comfortable and more focused at the same time. In other words, it gave them a state of meditated attention. In addition, it was found that the right brain was activated twice the intensity when the subjects worked through the geometric questions, whereas both sides of the brain were activated in equal magnitude during the process of arithmetic tasks. This replicates previous studies of the functional aspect of the right brain - being responsible for spatial and creative thinking.

The purpose of this study is to find out the present thermal environment of the Korean livingroom in comparison with the Japan's. Thermal environment of the livingroom with radiant floor heating system in Korea and Japan is analysed. The surveys and measurements are took place in two detached houses and two apartments in Seoul, Korea and two apartments in Tokyo, Japan for a 48-hour period at the beginning of March, 2003. The result of this study shows that the thermal environment of the livingroom in Korean houses, especially in the apartments is warmer and stabler than the Japan's. However, despite of its high temperature, Koreans have a tendency to rise their room temperature creating excess.
