The purposes of this study were to investigate the actual state of indoor air quality in semi-underground multi-family housing units in early summer, to analyze the influencing factors, and to make suggestions for improvement. A series of field investigations were conducted in four target units between June 22, 2010, and June 28, 2010. The field investigations included measurements of indoor air quality as well as the observation of architectural characteristics and living conditions. In addition to the field investigation, on-site questionnaire surveys were administrated to residents in 90 units. The findings are summarized as follows: (1) The average $CO_2$ levels in each of the four units ranged from 759ppm to 1885ppm. $CO_2$ levels in three units exceeded the evaluation standard (1000ppm), and one unit was lower than the standard. This unit had smaller number of staying person and a large amount of ventilation than others; (2) the average CO levels in each unit were almost 0ppm, but 0.1~1.1 levels of CO were revealed at several times; (3) the average PM-10 levels ranged from $8{\mu}g/m^3$ to $40{\mu}g/m^3$, which distributes within the standard ($150{\mu}g/m^3$). The influencing factors of PM-10 levels were analyzed as inflow from outside, the use of a gas range, and the residents' activities; (4) therefore, it was evaluated to be necessary to improve ventilation for the indoor air quality of semi-underground housing in aspect of $CO_2$ levels.

There is no compulsory administration on the facility status for silver medical welfare facilities under the current legal regulations based on the welfare law of the aged nor is there standardized space allotment conditions that considered the physical psychological and pathological characteristics of the aged.

In the past, station-area development projects were proceeded for modernizing the station facilities and improving the customer's convenience facilities by attracting private financing. But the site of station-are a development has a limitation that limits of benefits comparing with initial cost and absence of collateral by constructed the national property. For the advancing business value, merchandising facilities were adopted. There were many problems like coming the loss of city development opportunities. Now, station-area developments are considered the station and city plan. so, they are rapidly rised up the life in the station, need of making cultural space, improvement efficiency, combination and connectivity of transportation system and need of journey to Work Distance. Accordingly, this study suggests the station-area development projects by analysis of market conditions and forecast about housing and office that meets the trend of station-area development and secures feasible business value.

The purpose of this study was to develop the community programs of multihousing in Korea through evaluating and analyzing the actual conditions of community in multihousing in U.S.A. This study was conducted by using a field survey and questionaire at the 2 multihousing complexes located in the City of Blacksburg, Virginia, U.S.A. The major findings were as follows: 1) There was a variety of community programs and facilities, such as a monthly newsletter which allowed information to be exchanged among all residents. The programs also provided news on events for the children, teenagers, college students, adults and seniors. These events were held at the club house or pond area. 2) The average degree of satisfaction of these programs and facilities was high. 3) Korea need to follow the example of the U.S.A by i) providing a monthly newsletter periodically to exchange information ii) offering a variety of community programs iii) providing programs regarding district bureau of public administration, kindergarten service, telecommunications office and holding service for package, registered mail, drycleaning, etc.

This study was conducted to develop pig-housings based on the forecasting models of swine production, the weather conditions, and so on in Korea. The Korean pig-housings were developed according to the following basis : 1. They should be suitable to domestic weather conditions. 2. They should be designed based on the forecasting models of swine production of farrow to finish operation among the forecasting models of swine production in Korea. 3. Proper environments should be offered to pigs according to the growth. 4. The environmental control, the treatment of swine wastewater, and so on should be interrelated. 5. Manual energy should be saved by effective arrangements of pig-housings. In the future, performance test of the Korean pig-housings and development of facility automation systems which are suitable to these should be accomplished.

지금까지 연구해 온 바닥난방이 인체에 미치는 생리적, 심리적 영향에 관한 실험결과를 종합하여(건강한 여자를 피험자로 한 경우) 바닥난방의 Optimum Thermal Environmental Conditions 를 검토할 때는 다음의 조건을 만족시켜야 한다. (1) 저온 화상의 위험성을 고려하여 접촉부위의 피부온도가 $40^{\circ}C$를 넘지 않을 것. (2) 생리적 영향으로써 평균 피부온도가 $33{\;}-{\;}34^{\circ}C$의 범위일 것. (3) 심리적 영향으로써 온냉감 평가가 열적중성(slightly cool - slightly warm)으로 평가하고, 쾌적감 평가가 쾌적한 것으로 평가할 것. (4) 바닥온도에 대한 만족감 평가가 높을 것. (5) 흑구온도는 직접바닥에 앉는 자세에서는 $17^{\circ}C$ 이상, 의자에 앉는 자세에서는 $19^{\circ}C$ 이상일 것. 이상의 조건을 만족시키는 범위가 바닥난방의 Optimum Thermal Environmental Zone (Fig.7) 이라고 생각된다.
