Limited resources for construction material in the Mae-Hae region, a remote Northern Thailand, acted as an impetus to introduce a new way for constructing their dwellings. The new construction material brought new construction methodology, namely, using earth and bamboo which are indigenous materials, readily available for them to use. Using indigenous material at Mae-Hae region was most ecological and logical method for establishing sustainable dwellings both in terms of monetary and ecological reasons. Prior to the construction at Mae-Hae, Thailand, series of experimental tests on the strength of rammed earth were performed off site at our university and also brought soil samples from the actual job site at Mae-Hae for detailed soil analysis. Through the tests, integrity of the earth and characteristics of the soil were established to build a small senior citizen center as an example. This appropriate technology is expected to contribute to the sustainable construction at Mae-Hae.

Since the apartment was built in 1961, the amount of its supply has been increased greatly, especially from the late 70's. The ratio of apartment housing to detached housing was already over 65% in 2000, and now the apartment becomes the most general type in domestic dwellings. But from 90's, the residents of apartment housing have been dissatisfied with the indoor noises and have issued civic petitions. Some national assemblymen front new towns where a high rise apartment is common are interested in This problem, and promise that they try to solve it. The government has also enacted the related regulations. This paper presents the present state and action plans of indoor noise in dwellings. Details on these will be demonstrated at the presentation.

A simulation study was conducted to use city-water which is thermally regulated by unused energy as a heat source for urban dwellings. This study utilized multiple heat pump system using the city-water as a heat source and suggested a method of reducing the heat load of hot water supply. The simulation was done to calculate the energy savings at a dwelling for a year. The relation between the controlled temperature of city-water. and electric energy in all seasons was also investigated. Furthermore, it has been found that the controlled water system can lead to considerable energy savings and decrease environmental load such as sensible waste heat which otherwise would form heat islands.

In order to provide the basic data for planning of housing safety, the actual conditions of home accidents were analyzed. As research data, the medical charts of patients on the general hospital in the large city in two years 1987 and 1992 were used. The rate of home accidents increased in 1992. Children had more accidents than others and single family dwellings were the predominant place of accidents. The accidents slip frequently occured(21.1%), with respect to the place, room was the main place of accidents(40.5%), the accidents in a living room and a kitchen increased in 1992. 59.2% of the total patients were slightly injured, the faulty design was the main cause of the accidents and the acciednts by the personal factor increased in 1992. In the next study(III), I'm going to analyze the relationships among types of accidents, places of accidents, defrees of accidents, causes of accidents, and the personal characteristics of patients.

Beijing Chuan Di Xia can be traced back to Ming and Qing Dynasties. It is located beside the old post way in the west of Beijing. At present, there are more than seventy units of traditional courtyard houses of Ming and Qing Dynasties and the antique features of the surroundings still survive. The dwelling suited to the historical and regional context and the profound cultural values accumulations etc., have precious historic and cultural values. Associated with the investigation of Chuan Di Xia, the paper explores the site selection, the layout, the spatial constructiveness and the underlying consciousness of Chinese traditional dwellings, unveils the common philosophic basis of traditional dwellings and offers new though for sustainable human settlements.

The formation of Chinese Town in Malacca of Malaysia and Singapore would explain that Chinese gradually played an important role of commerce and urban service according to the Western European advance to southeast Asia and the construction of colonial cities from the 16th century to 19th and massed residence in many cites of southeast Asia. Chinese was usually separated from the Western European by western colonial policy and city planning. Common architectural characteristics in Chinese towns of Malaysia can refer to the transmission of the Chinese architectural material, the combination of dwelling and commerce in a house and the space organization centered on a court or an air well in the narrow and long site, lying adjacent to street etc. The Chinese dwellings in Malaysia rooted with Chinese settlement in southeast Asia. The Chinese dwellings was not always a shop on 1th floor and a dwelling on 2nd floor before the 19th century. But as Chinese immigration and commercial activity progressed in earnest in the early of 19th century, the row house of Chinese for dwelling was autonomously changed to two functional shophouse for dwelling and commerce. Chinese row house can refer to the use of Malay regional material, change of symmetrical Chinese traditional housing type by the narrow and long site and the tendency of the eclectic elevation of Western and China. Another architectural characteristics of the shophouse is an appearance of the continuous verandah with a cover regulated by Stamford Raffles in Singapore. This regulation was applied to architecture in Chinese Town as Stamford Raffles constructed Singapore. It was spread to South China reversely and became the regulation of streetscape for the modern city. Shophouse of Chinese towns in Southeast Asia and south China can be understood by context of Chinese immigration, colonialism, housing type of commerce and dwelling and the Western European city planning.

Radon is a naturally occurring radioactive gas and a major indoor contribution of exposure to ionizing radiation in dwellings. $^{222}Rn$ is a health hazard gas what is responsible for thousand lung cancer deaths every year. In this study, indoor radon concentrations present in thirty representative houses in Mahallat city, Iran, were determined in order to estimate lung cancer risk associated with residential radon exposure. Long-term passive method, using CR-39, was used to measure the radon concentration. The results showed an association between the age of the dwellings and the indoor radon concentration that was found, in that the concentration of radon tended to increase as the age of the dwelling also increased. The indoor radon concentrations were calculated to be within the range of $23{\pm}2$ to $350{\pm}26Bq{\cdot}m^{-3}$, with an average of $158Bq{\cdot}m^{-3}$. The annual effective dose from inhaled radon and its decay products was calculated between $0.8{\pm}0.1$ and $12.3{\pm}0.9mSv{\cdot}y^{-1}$, with an average of $5.5mSv{\cdot}y^{-1}$. By taking into consideration the EPA recommendation and ICRP statement, the average annual risk of lung cancer from inhaled radon was calculated as 0.09%, 0.06%, 0.01%, and 0.03% for current smokers (CS), those who had ever smoked (ES), never smokers (NS) and the general population, respectively.

Objective: This study was designed to compare construction types and seasonal radon concentrations in dwellings in Jeollabuk-do Province in Korea. Methods: The measurement of indoor radon concentrations in 79 dwellings using alpha-track detectors was performed every three months (seasonally) over one year between 2015 and 2016. Also, Radon concentrations in soil were measured in spring to investigate the correlations between the concentrations in soil and indoor air. Results: The annual average concentration of indoor radon for dwellings was 89.7±72.1(GM: 72.4) Bq/㎥, with a range (min-max) of 17.2 to 505.4 Bq/㎥. The highest indoor radon concentration was measured in winter and the lowest was shown in summer. The geometric mean of radon concentration in winter was 1.03-2.58 times higher than other seasons. Radon concentrations in soil were investigated at the depth of 1 m, and the concentrations ranged from 1,780 Bq/㎥ to 123,264 Bq/㎥. This showed low correlations with indoor radon concentrations.
