The research analyzes the arrangement of boiler and hot water header, the method of radiator pipe setting, hot water supply control, hourly heating situation of each room for underfloor radiant heating systems in Korea and suggests an alternative to improve to efficient heating method. One of the best options for install position of hot water distributor is under kitchen sink which is center point of all rooms, according to previous research of the energy saving strategies. When the radiator pipes are arranged to each individual room instead of bedrooms through livingroom and kitchen, it has energy saving effects. For rooms without occupancy according to a time period, hot water supply method should be intermittent heating rather than continuous heating. For this intermittent heating method, individual control of hot water supply is more practical, and it can lead to massive energy savings. The intermittent heating system has time-lag, so it is more effective in energy saving with mild and comfort condition if the spaces are preheated by automatic control equipment prior to required time.

In contemporary housing design, this cultural value has been ignored. Contemporary design has adapted quickly to global trends and houses have gradually lost their cultural identity (GhaffarianHoseini & Dahlan, 2012; Lim, 2001). Nevertheless, traditional housing culture persists in people's behavior and thoughts. Therefore, there is currently a pressing need to rebuild cultural identity in housing for cultural sustainability. This study aimed to analyze the traditional culture which was maintained, then transformed and disappeared in housing design through the quantitative survey and explore the cultural identity of Malaysian housing as a result. A quantitative survey was distributed to mothers of 129 married households living in a metropolitan area of Kuala Lumpur in August 2019. As a result, it was found that hosting guest was important even though the designated space (serambi) was disappeared. The LD/K layout, separating kitchen from living and dining area was philosophical and practical culture, still strong among older generation, but weakened among younger generation. To accommodate the traditional habit of diverse household work, wet kitchen, utility space for washing machine & drying, and outdoor space were needed to design carefully. When applied to future housing design, the findings will contribute to enhancing quality of life by strengthening residents' sense of place and social cohesion and by providing a culturally inherent design that eases the effects of globalization.

The purpose of this study were ; (1) to analyze the relationship between actual housing condition and housing satisfaction with socio-demographic and housing characteristics of respondents and (2) to present the device on the quality of housing environment in low-income families. The sample was a proportional, stratified, random sample of 299 low-income families in Deajeon. The major findings were as follows: 1) The wholey, actual housing conditions were not good; especially the worst conditions appeared exterior walls, roof, kitchen, bath and toilet, heating, noise, recreation facilities as play-ground. 2) Actual housing condition has been found to be related to income, tenure(rent or own), persons/room. In the relation of the socio-demographic and housing characteristics, actual housing condition, housing satisfaction, income and persons/room were found to be a significant explanatory variable in actual housing condition. And actual housing condition ws appeared to be the strongest variable in housing satisfaction. 3) Housing of the low-income families should be improved physical aspects of the environment and be reflected in need of the occupant that based on the social-welfare housing concept.

Whole column coldtrapping(WCC) on a fused silica capillary (FSCC)combined with GC/MS analysis was evaluated for use in the investigation of volatile organic compounds(VOCs) in indoor air. Research had indicated that a temperature of $-80^{\circ}C$ is optimal for WCC. Samples were analyzed on a $50m{\times}0.2mm$ cross-linked 5% phenylmethylsilicone fused silica column. Liquid nitrogen was used as the coolant for the peak resolution significantly. The analysis can be performed quickly and conveniently. More than 112 of VOCs were determined in the samples from three typical indoor environment including: (1) a room which had just been decorated involving building materials and paints; (2)a kitchen used for Chinese cooking, and (3) a room had tobacco smoke. The method is could be readily applied to rapid sample screening for VOCs contamination surveys or initial investigations with its valid and simple sampling and analytical technique.
