  • Although peak loading coefficient is one of critical design factors for sewer works, its detailed affecting factors were not analyzed because of limited data availability. This study analyzed the affecting factors on peak loading coefficient with plenty data obtained from several newly constructed sewer works. Simple and multiple regression analysis methods were adopted to analyze the relationships of each variable with or without data filtering. Drainage population, drainage area, population density, and daily sewage flow per person showed very weak relationships under diverse characteristics of cities. However, daily sewage flow per person showed stronger relationships with peak loading when daily sewage flow per person was splitted into two ranges. Population density (i.e., drainage population divided by drainage area) and daily sewage flow per person considerably were related with peak loading coefficient when daily sewage flow per person is less than about 400 Lpcd.

  • Currently, the United States, the United Kingdom, Australia etc. are actively utilizing energy simulation for efficiency evaluation of building energy. However, domestic energy efficiency assessment system doesn't use energy simulation system properly at present: parameters based architecture plans and Ashrae Standard are inputted for the evaluation, because the input parameters for the simulation haven't been established yet. This fact causes poor reliability during energy simulation, as the values of the two standards are different from each other. Therefore, the aim of the study is to set domestic standard parameter for BIM-based energy performance evaluation, focusing on possession area per person of occupants at government office in Korea. We found that the difference among the result values occurred approximately 3% in the energy simulation. As a result of the analysis, possession area per person of occupants in Government office is $31.87m^2$. Other input parameters may be set based on this. This will increase the reliability of energy simulation through a domestic standard parameter.

  • Parks in Kwang Ju ar determined by the development of a housing project under the regulations of land development rather than the planning approach of park provision. This study tries to identify who is the provider of parks, to estimate the size of urban parks per person in the area of the housing project, to look at the spatial allocation patterns of park provision and to identify the character profiles of users and the social profile of an ares(Dong). This research has produced the following major conclusions : 1. The city government should set up a master plan of park provision to control park delivery system to avoid maldistribution. 2. A positive discrimination policy should be introduced to disadvantaged areas in terms of park provision. 3. The null hypothesis - there is no relationship between distance and park Use - is rejected by the correlation rate of 0.4984. 4. The ratio of parks per a person ; 10.43㎡/person in 1990 has decreased to 10.41㎡ /person in 1994. This means that the increase of parks in terms of quantity could not catch up the increase of population.

  • The objective of this study was to estimate changes on the flood and nutrient intake patterns of men over thirty years old in Jeon-Ju area. The first survey was conducted from December in 1991 to January in 1992, tile second one from January to February in 1994 and the third one from July to August in 1997. The nutrition survey using 24-hour recall method was executed to 303 subjects : 89, 82, 132 in 1991, 1994 and 1997, respectively. Results of the study are as follows : Kimchi, rice, garlic and onions were the most frequently eaten food items. Total daily intakes of foods were 85 : 15, 81 : 19 and 81 : 19 in 1991, 1994 and 1997, respectively. The average numbers of foods per person were 15.7, 20.1 and 21.9 daily in 1991, 1994 and 1997, respectively and tends to increase significantly(p<0.05). The minimum numbers of foods per person were 4, 7 and 9 and the maximum numbers of foods per person were 27, 35 and 39 in 1991, 1994 and 1997, respectively. KDDS(Korean\`s Dietary Diversity Score) is determined by how many among the five food groups (cereals, vegetables, meats, milks, oils groups)were consumed per day. Most subjects earned the KDDS "3" ; 61, 46 and 42% in 1991, 1994 and 1997, respectively. Average daily energy intakes wee 1,62㎉(72% of RDA), 2,063㎉(89% of RDA) and 1,818㎉ (79% of RDA) in 1991, 1994 and 1997, respectively. Energy intake rates of cereals : total energy intake were 65, 59, and 60% in 1991, 1994 and 1997, respectively, which were decreasing. Protein intakes were 58g(72% of RDA), 79g(107% of RDA) and 71g(97% of RDA), respectively and animal protein comprised 46, 53, and 59%, respectively ; which were increased. Fat intakes were 12g, 20g and 20g, respectively and animal protein comprised 38, 46, and 48% ; which were increased. Fat intakes were 12g, 20g and 20g, respectively, of which animal fat comprised 46, 53, and 59%, respectively ; which were increased, too. Malnourished (under 75% of RDA) rates were respectively 64, 34, and 47% in terms of energy ; 64, 31 and 33% in protein ; 67, 51, and 61% in calcium ; 53, 26, and 18% in iron ; 85, 74 and 84% in Vitamin A. Super-nourished(above 125% of RDA) rates were respectively 1, 13, and 3% in energy ; 1, 29, and 21% in protein ; 5, 18, and 7% in calcium ; 16, 31, and 7% in iron ; 16, 31, and 7% in Vitamin A, 42, 76, and 62% in Vitamin C. The percentages of calories from protein : fat : carbohydrate were 14 : 12 : 74, 15 : 16 : 69 and 16 : 17 : 67 in 1991, 1994 and 1997, respectively. KDDS(number of five food groups per day), Meal Balance(number of five food groups per meal), DVS(average numbers of foods per person), amount of foods correlated positively with all the nutrient intakes(p<0.05). KDDS was positively correlated with energy, protein, fat, calcium, thiamin, riboflavin and niacin(p<0.05)in(p<0.05)

  • This study aims at providing basic policy materials to build a basis for supplying and creating urban parks balanced across Gyeonggi province and improving the quality of life of residents through, an extensive analysis of all city parks in cities/counties in Gyeonggi province. The study result showed that first, the number of parks is only 40% of the adequate number and, thus, accessibility of Gyeonggi province residents to parks in neighborhoods is significantly low. Second, a proportion of park types in children's park, neighborhood park, urban nature park is 67% : 24% : 2%, which is adequate in Gyeonggi province as a whole. Third, as for the area of parks per resident, the area of designated park is $17.7m^2$/person, which is over three times of legal requirement in urban planning area ($6m^2$/person). However, created park area is only $5.6m^2$/person, which fails to meet the legal requirement. Fourth, when park area of each city was compared, the areas varied significantly across cities. The Gyeonggi provincial government needs to secure funds aggressively and accelerate setting up and expanding facilities at designated parks located within the current urban areas. The findings from this study should be used as important materials when developing supply & demand policies for urban parks in Gyeonggi province. The study implicates that independent park policies and management by each city/county as well as the establishment and management of a comprehensive park policy at a provincial level is significantly important.

  • After the 1988 Seoul Olympics, a lot of Culture & Arts Centers have been built in Korea. There have been raised questions on the frequency of room use and the occupancy of seats, but there are not enough architectural data for the Culture & Arts Centers in Korea. This paper focuses on the investigation of the architectural features of the Culture & Art Centers, such as the spatial sizes, the composition ratio of the performing art hall area to the overall facility area, the sizes and proportions of seat zone to stage zone, the average area per one person at the seat zone, the wide and the height of the procenium, the height of fly loft, and the number of users per one program. We could find out some meaning results. The composition ratios of the performing art hall area to the overall area of the facilities distribute with a wide range. The floor areas of 1500 through 2000 seat performing art halls are larger than $13,000m^2$. The average area per one person for seat zone and stage zone is approximately $0.8m^2$. All facilities we investigated have the types of the procenium stage. Almost all of the facilities have high quality stage conditions and equipments, but few programs use the various stage equipments and all of the main, side, and rear stages. To resolve this problems, various programs have to be developed for encouraging more people to use the Culture & Art Centers.
