In order to examine the effect of impermeable surface (rooftop, outdoor parking lot) and rainwater infiltration facilities on runoff pH, pH was measured. pH measurement spots were splash blocks accepted roof runoff of 3 sites, infiltration boxes and trenches accepted parking lot runoff and plastic rainwater harvesting facility accepted roof runoff. These measurements were operated at 3 housing complexes from 2006 to 2009. The rainwater runoff pH was influenced by the quality of the runoff surface material (concrete), the age of the building, waterproofing methods according to each housing site, antecedent rainfall conditions and others. Rain garden, infiltration boxes and trenches decreased the alkalinity of runoff by detention and infiltrating the roof and outdoor parking lot runoff. These results mean that decentralized rainwater management facilities of housing complexes can reduce effect on the outskirt aquatic ecosystem by the accumulation of substances causing pH rising in the infiltration facilities and rain garden.

Complex environmental control systems were developed, which control properly the pig's environment in windowless pig-housing based on the thermoregulatory behaviors of pigs and concentrations of noxious gases (CO2 and NH3). The this study was conducted to assess the performance of complex environmental control systems by raising weaned piglets and growing pigs under different seasonal conditions. Average daily gain of pigs in the experimental pig-housing was slightly higher than that of pigs in the conventional pig-housing. Average daily gain was not significantly different in winter and spring(P＞0.05), but was significantly different in summer(P＜0.05). Feed conversion rate of pigs in the experimental pig-housing was smaller than that of pigs in the conventional pig-housing. Feed conversion rate was not significantly different in environment for weaned piglets and growing pigs resulted in the improved daily gain, feed conversion rate, and carcass quality of the finishing pigs. These results showed that the performance of the complex environmental control systems in windowless pig-housing was excellent for weaned piglets and growing pigs.

According to the aging society, the housing environments of senior citizens who live alone are faced with social various problems. On the dwelling welfare, development of model for the silver house is necessary at the reducing of social expense. Particularly, the silver housing conditions of rural and fishing villages are poor than urban region. The results of this research are as follows. First, the senior citizens who live alone looked to an negative opinion about cohabitation of the aged, but the senior citizens who don't live alone and preliminary old man group showed a positive opinion to the regarding cohabitation. Second, Most of the aged was in poor health, On this account they expressed an opinion that they were opposite to the cohabitation opinion. Although considering health, simultaneous design of both private life and community life shall be reflected to the preferential design element in co-housing of the aged. Through these co-housing for the aged in rural and fishing village, the senior citizens who lives alone have prevented poor housing surroundings, loneliness, loss of role, uneasiness, gloomy, chronic disease.

This research is according to the a future-oriented strategy, low-carbon green growth, and it is a basic research for dissemination of rural housing standard plan. Through the survey of plans use, we look at ways to rural housing standard plan use and then needed to establish measures for this. Looking at the type of used plans, we can find several points. One of them, 19 kinds of rural housing standard plans were used among the 61 total cases. Almost all change the plan, the reasons is different for the condition of the land, such as site conditions, family members, personal preferences, house color or material. A few cases have been constructed as rural housing standard plans, but rural housing standard plans are important data for the rural resident to determine plans, and it has an important role in the rural housing design process. Common features of the many rural houses is concrete structure, two stories, and construction period is two to three months. Land area is $300m^2$ to $600m^2$, building area is $71m^2-110m^2$. Heating system is an oil boiler.

With both Gatdui and Daean areas, under construction for upgrading the old housing in Gyeongju downtown area, this study was carried out to find out implications of upgrading methods in a historical and cultural city, by using a physical survey in the areas and life survey among their residents, as well as by analysing the level of their satisfaction with and requirement for housing and their preferring housing type. The upgrading patterns of residents were analysed by examining cases constructed newly in the manner of upgrading. The findings showed that it is required for both existing authorities and private parties to assume roles and responsibilities for upgrading the old housing while recently there have been continuous conflicts between development and preservation of the historic and cultural resources within the city and even the city identity also has been neglected by residents. In addition, it is necessary to take development conditions and resident's economic situation into consideration and introduce a wide range of methods for rearrangement, by turning the importance of housing upgrading to social rearrangement for the purpose of positive alternation.

The demographic profile of the households will shift towards the 'older elderly'. There are need upgrading existing housing and new housing in aspect of floor plan, accessories, facilities and so on. The government should prepare the policy and standards of housing design for the aged and disabled in order to improving the residents' housing conditions. The purpose of this study is to compare Korean to foreign guidelines related to residential design for the elderly and disabled and find out the characteristics of our standards. It was accomplished by literature research. The results were as follows. There is disagreements between domestic standards over the clear door opening, the clear hallways and handrails at entrance. And the foreign standards are based on their wheelchair size, ours are founded on it's size which specified only maximum overall dimensions. So ours are seem to be lack of accuracy. Our standard of stairs is in details in comparison with other space components. But ours don't go into details than foreign ones over length of hand-rails, riser etc. And for recommendations denoting minimum and maximum height of various component, it should be preceded the specific survey on limits of reaching ability for the elderly and disabled.

Aging in place strategies such as residential remodeling have potential to enable older persons to remain in their own homes satisfactorily in terms of quality of life. The purpose of this study is to investigate the types of residential remodeling, needs, and opinions of elderly households living in Seoul and to suggest the housing policy and system for improving independent living of elderly households. Using face to face interview with structured questionnaire, 115 elderly households were interviewed during April $25{\sim}June$ 25, 2005. Most of respondents wanted to stay in their own homes as long as they can and some of them remodeled their houses to adapt their physical and financial conditions and housing needs. Various factors such as financial problem and lack of knowledge about remodeling process, however, restricted their actions to realize their needs. Based on the results, some suggestions to activate 'aging in place' were proposed as future guidelines of housing policy related to residential remodeling for housing welfare of the elderly.

There are similarities between Korea and Japan in terms of national planning and development system and housing policies. Japan has suffered from great shifts of social and economic systems due to skyrocketing land prices for three times and the collapse of the bubble economy after the Second World War. The study reviews historically important changes in the national territory and housing policies for last 60 years in Japan. It also investigates changing trends and characteristics of many socioeconomic indicators with regard to population, housing and other fields in response to these policies. First of all, Japan has experienced significant economic growth before and after the 1960's, and the era of national rebuilding projects in the 1970's. After then, the period of the bubble economy has emerged since 1980; however, it suffered from skyrocketing land values between the late 1980's and the early 1990's, and the collapse of Japanese bubble economy in the early 1990's. In response, many urban regeneration policies and projects were proposed to recover the national economy since 2000. It is found that these national territory development and housing supply policies throughout the country have been influenced by the changing characteristics of social and economic conditions. Since the housing supply ratio in 1968 reached up to around 100% on average, Japan has been focusing attention to improving the residential and living quality for existing housing stock rather than supplying new housing units through large-scale new town projects. These experiences are full of helpful suggestions for our future housing and urban regeneration policies as we reach to more than 100% of housing supply ratio on average.

Ji, Syok-young wrote a book named Sinhaksinseol(新學新說) in 1891, one of the first hygiene books in Korea. There were the conditions of modern housing like lighting, ventilation and dry and fresh air of a housing site in the contents of the book. Because the book was written when the modern hygiene theory had just been accepted, traditional concept of 'Yangseng(養生),' but it dealt the main environmental conditions of hygienic housing at first, which makes it the leader of modern housing discourses through the newspapers, magazines, academic journals or textbooks from 1890s mid to 1910.
