Nowadays, according to the interests in the environmental infinity for the housing complex, there are various studies going on for setting general ideas and plans of them. And in some of the leading places are applied by the infinity of the natural environment. So, by this study, I analyzed the classification and the system of the infiltrated facilities for the rainwater and then suggested the problems about these and the studies for the generalization of the infiltrated facilities for the rainwater based on my real investigation of the center of infiltrated facilities for the rainwater in the Kiheung, Sangal Kum Hwa Village designed and builded by the Korea Housing Corporation for building housing complex with the infinity of the natural environment. I grasped the realities based on subject investigations and designs and found out the infiltrated facilities for the rainwater in the subject. Those are the porous concretes, pebbles and cobbles. The problems in the subject are supervision of these places and a shoddy and fault constructions by the ignorance and lack of recognition for the construction. These will be solved by reconsidering of the infiltrated facilities for the rainwater. The system of the infiltration is that the rainwater of the top of the building flows into the brook in the subject through the field of the subject. There must be going to be leading studies on the effect of these facilities and influence on the environment for the generalization of the infiltrated facilities for the rainwater of natural environment.

The phosphorus contribution rate on water quality of North and South-Han River, and Gyungan-cheon by effluents from environmental fundamental facilities located in upstream basin of Paldang Lake were analyzed. QUALKO2 model was selected for the analysis of contrubution rate, and was constructed considering the location of the main point sources and all facilities in study area. The pollutant loading rates and arrival rates for each unit-watershed in study area were calculated for model operation. For the calibration and verification of model, 2006 water quality dataset from Ministry of Environment and the effluent loadings of the environmental fundamental facilities were used. Reliability Index (RI) method was used to estimate the validity of the results of calibration and verification. The phosphorous contribution rate(%) for each environmental fundamental facility were analyzed by excepting the effluent loading of the facility. The contribution rate was analyzed for each facility, facility groups separated by each main river and each unit-watershed. The main results of analysis for each facility are as follows; (i) the phosphorous contribution of B1 facility is 50%, which is the highest phosphorous contribution rate among those of nine facilities in the North-Han River Basin; (ii) the highest phosphorous contribution is 55.6% from J facility among eight facilities in the Gyungan Stream Basin; (iii) 40% from E treatment facility is the highest among those of twenty eight facilities in the South-Han River Basin.

In this study, we investigated the characteristics of Volatile Organic Compounds(VOCs) emission from painting and printing facilities in the Pyeongdong industrial complex in Gwangju. In addition, the objective was to understand the distribution characteristics of VOCs in the ambient air in industrial complexes affected by painting and printing facilities. The painting facility mainly emitted toluene, acetone, butyl acetate, 4-methyl-2-pentanone, ethyl acetate, 1-butanol, methyl ethyl ketone, m,p-xylene, o-xylene, 4-ethyltoluene, ethylbenzene, 3-ethyltoluene, and 1,2,4-trimethylbenzene. The main emission components in printing facilities were methyl ketone, ethyl acetate, acetone, 2-propanol, toluene, heptane, and butyl acetate. Ethyl acetate, toluene, 2-butanone, acetone, butyl acetate, 2-propanol, xylenes, and 4-methyl-2-pentanone were detected in the ambient air of the Pyeongdong industrial complex, consistent with the VOCs emitted by painting and printing facilities. The average concentration of seasonal TVOCs followed an order of winter > fall > spring > summer, whereas the concentrations of daytime and nighttime TVOCs were generally higher at night than those during the day, and the wind speed was greater during the day than it was at night. Based on a factor analysis of VOCs in the ambient air of Pyeongdong industrial complex, it is considered that organic solvents used in coating, printing, and electronics manufacturing facilities, as well as diesel vehicle emissions played a major role.

The purpose of this study was to identity the probability of cross-contamination from the environment. For this, we examined foodservices at 20 universities/colleges for microbiological analysis of their working facilities and environment as well as their preventive equipment against cross-contamination. Seventy percent of the 20 foodservices were found to maintain one unified working area, which suggests high probability of contamination of food/utensils/equipment in the cooking area by pre-preparation or dish washing. According to the microbiological analysis, the hygiene acceptance ratio of working facilities in the clean zone was 70%, which was higher than the average 45% hygiene acceptance ratio of working facilities in the contamination operating zone. There was a significant difference in the total plate count (P<0.001) and coliform count (P<0.01), which demonstrates that work tables in the clean zone were in a good state compared to those in the contamination operating zone. In the contamination operating zone, refrigerator shelves had a high probability of cross-contamination. Regarding the floor surface and airborne microbes, cooking areas which should be maintained as clean zones had higher cross-contamination probability than those in the contamination operating zone. So corrective actions such as cleaning and sanitizing, keeping dry floors, lowered temperature and humidity, shoe disinfecting facilities, and checking concentrations, are necessary to manage floor surfaces and airborne microbes in the cooking area.

The purpose of this paper is to suggest the preliminary data for the improvement of the senior centers' indoor environment and the upcoming progress located in rural areas. In wanju county, 81.8% of seniors were enrolled in senior centers, and used the facility everyday. Also, most of the users tended to use the facilities between 12 a.m. and 6 p.m. The majority of users had lunch at the senior centers. The facilities of most senior centers were in poor condition, and some had their restroom outdoor. Also, most senior centers are exposed to high concentrations of carbon dioxide during winter. During this season, the thermal environment in the restroom was bad. However, the users' level of the facilities' satisfaction was positive. Senior centers have been operating the facilities with difficulties, due to the low financial support from the local autonomous organization. The indoor temperature in most centers, especially, was above $30^{\circ}C$ during summer on account of lack of funding for airconditioning. Therefore, it could be recommended that the local autonomous entity start regular check-ups and repairs for the poor indoor environment and facilities, with more financial support and active supervision of the management.

As the living standard of citizens are improving and the demand for the quality of life is increasing, the demand for the facilities of welfare and convenience for varied ages rises. Besides, our residential environment is faced with the need for changing into the environment of integrated function of living, which holds health, leisure, culture, education, welfare, etc. Considering the present reality requiring the augment of welfare facilities due to our aging society, community integrated facilities are needed, which can contain welfare service for home-living citizens within residential circle and can accept diverse needs of residents. Accordingly, the study began in order to suggest a better direction for community integrated facilities' plan that considers all age brackets for aging society. The study is to figure out way of thinking what community space of 3 age cluster middle-age in the 30s~40s, preparatory senior citizen in the 50s and old age brackets in the 60s~70s. As methods for attaining the aim of this study, surveys of documents and questionnaire survey were simultaneously used. The result of the study, investigating the importance of a community among the members in the residential complex, showed that all the age groups have highly perceived its importance. All the age groups responded that leisure are important to the elderly. It indicates that importance of their social relations are within the residential environment and it proves that there is lack of facilities for leisure activities of residents in apartment house.

Purpose: As the concerns for the environment are gradually prioritized, increasing interests of environment-friendly buildings are drawn. The Green Standard for Energy & Environmental Design (G-SEED) has been strengthened. However, there are no specific assessment criteria that reflect the special situation of healthcare facility. UK, US and Japan have green building certifications specially designed to evaluate sustainable healthcare facilities. This study has been started in order to provide basic information for developing assessment criteria for healthcare facilities in Korean Green Standard for Energy and Environmental Design. Methods: In this study, we investigated three foreign green building certifications and compared their assessment system and criteria for healthcare buildings. Results: Each of the three foreign certification standards showed the difference in the system, but all contained the contents specific to healthcare facilities. Evaluation items were affected by regional cultural environment and also medical environment. Patient safety and integrative planning were the most important assessment contents. Implications: Based on this analysis, Korean Green Standard for Energy & Environmental Design for healthcare facilities will be developed.
