In residential spaces, sanitary zones are where the most basic needs of human beings are met and are used by all members of the family. A high level of privacy is therefore required in their use. This research studies the current state of sanitary zones in collective houses and in detached houses from a comparative perspective first, and then analyses the satisfaction and dissatisfaction requirement levels of dwellers of each house in comparison so as to provide data to formulate a new design for sanitary zones that is suitable for each dwelling house. The results of this research are as follows. (1) The questionnaire respondents were mostly in their 30s and 40s (99.1% in total), and lived in a nuclear family system (87.7%). (2) The number of sanitary zones was found to be more than 2 in 62% of collective houses and in 60.7% of detached houses, which leads us to conclude that non-dwelling spaces are increasing in both types of houses. (3) Of the housing facilities,13% of collective houses and 9% of detached houses were equipped with a bidet. Both percentages are very low but it needs to be noted that the percentage is relatively high in collective houses. In safety facilities, the ratio of houses furnished with safety handlers for the aged was very low in both types of houses. (4) The residents of collective houses showed high levels of dissatisfaction with regard to the problems of storage space and steam production, while residents of detached houses expressed high levels of dissatisfaction with regard to the heating system, colors of finishing materials, size, dampness, steam production, and storage space.

An analytic and comparative study on the level of concentration on heavy metals in silt of Han- River was described. The Paldang lake supplies tap water resources for the 20 million residents in the metropolitan zone. It is composed that three steps for water works by the water volume in all 35,072 thousand tons : the first section is 7,251 thousand tons, the second is 15,980 thousand tons and the third is 11,841 thousand tons. However, recently it has becoming a serious social issue for water contamination on Paldang by heavy metals due to gathering of silt. It has concentrated on analysis and comparison study on the level of heavy metals between contamination- estimated zone and the other zones. After all, Concentration on heavy metals of expected none pollute's zone and expected pollute's zone indicate almost similar results. In the end, heavy metals within silt of Han- River consider not to effect on pollution but quantity of natural condition.

This study aims to investigate planning characteristics of common and living space in the dormitory buildings on campus in Chungcheong province. A document research method was used to analyze and classified into floor-plan, zoning and area. Also site visits were conducted at 8 dormitory buildings of 4 universities, and drawings were collected and compared for this research. The results of this study were as follows; 1)Most floor plans of public spaces had corridor types and integrated public space types. The typical floorplan of living space was 2person-1bedroom and apartment type which shared livingroom, bathroom, restroom and shower between bedrooms. The living space type of dormitory buildings was more complex and growth in size. Unit community combined 2-4person per 1bedroom in floor plan can help student with identity and affiliated formation. 2)The types of the spatial composition in public spaces were devided into three zones; study, living and administrative zones such as seminar room, public bathroom and storage, etc. This results shows that various types of public space for the improvement of community of small group has recently become more important than basic sanitary space in public space of dormitory buildings on campus.

This study was carried out to investigate foodservice management practices of 100 child care centers nationwide, and to provide background information for developing foodservice management policies at child care centers. Approximately 20% of the child care centers had a separate dining room; most of the centers were vulnerable to sanitation or safety problems. The percentage of the centers that planned menus was about 60% and 10% established standardized recipes. Fourteen percent of the centers kept records for distribution and menu evaluation and 33% kept sanitation management records. Since only 7% of the centers employed a dietitian, foodservice in most centers were not managed by professionals. The results of menu assessment revealed that 56.5% of the national/public child care centers received 19 points or higher out of 21 points, whereas 5.6% of the private child care centers received the same scores. Proper usage and storage of raw food, sanitary management of equipment and facilities, waste management/leftover food treatment, and basic facility of cooking zones were performed well by many centers. The overall scores of foodservice performance were only 31.2 out of 60 points, representing relatively poor safety management, food procurement management, and facilities and equipment management. These results indicate that the foodservice management of the child care centers are in a relatively poor state. Since nutrition management of the most centers was performed by non-professionals, it may not be possible to provide proper nutrition for health and normal growth of preschool children and to perform efficient nutrition education programs. The following suggestions are strongly recommended in order to improve foodservice performance at child care centers. First, foodservice administration should be performed by a dietitian, and second, efforts should be focused on strengthening nutrition and sanitation management.

This study examined the environmental characteristics of shore pollution sources in the southern part of the Sinan, Jangsando area in the West Coast of Korea. A shoreline survey of the watershed was conducted to identify the pollution sources and measure the water discharge rate and microbial hygiene of water and finally estimate the possible impact area of pollution. Forty five of pollution sources in total were identified and they were grouped into sewage (33), agriculture waste water (1) and waste water from inland fish farm (11). Nine among them were discharged into the seawater and discharge volume was 72,857~281,250 l/min. Fecal coliforms of St. 72 (sewage) and St. 74 (shrimp farm) were 490 MPN/100 ml and 49 MPN/100 ml and the impact zones of the pollution were 4,389 m and 1,900 m respectively.
