The purpose of this study was to compare the characteristics of floor plan of $85m^2$-sized housing units with 2-bay and 3-bay and the residents' satisfaction with them. The subjects for analyzing floor plan were six floor plans of $85m^2$-sized housing units with 2-bay and nine floor plans of housing units with 3-bay in the new town, Hwamyeong-dong, in Busan. The floor plans were analyzed based on seven characteristics of floor plans such as the composition type of entrance core hall, the entrance arrangement, width and depth of the housing unit, size of each room, LDK arrangement, arrangement of family bathroom and private bathroom for husband and wife, and balcony arrangement. The subjects for grasping satisfaction with each housing unit were 400 residents of $85m^2$-sized housing units. A half of them lived in housing units with 2-bay and another half of them with 3-bay in the same area. They answered about the degree of satisfaction with the characteristics of each room and the preferred floor plan type if they move to the same size housing units through a questionnaire. The results were as follows; First, the floor plan with 3-bay had more diverse elements than one with 2-bay. Second, the residents who lived in 3-bay housing unit were younger, higher education, and higher income than the ones in 2-bay. Third, the residents who lived in $85m^2$-sized housing unit were more satisfied with and preferred to 3-bay housing units than 2-bay one.

In this study, by comparing the development and the space types of local and foreign flexible apartments, basic data will be derived for the development of various flexible types of apartments in Korea. A total of 60 unit plans, including 30 domestic cases and 30 overseas cases of flexible apartments, are analyzed for this study. In terms of the unit plan types, Korean apartments usually had a wide front bay with shallow depth, placing more rooms on the front bay; whereas foreign apartments tend to have various unit plan types: (1) a narrow front bay with deep depth, (2) a wide front bay with shallow depth, and (3) variegated open-plan types. Many apartments in foreign countries had a double-layered structure with the. upstairs and downstairs areas. In terms of the flexible types, many Korean apartments achieved interior flexibility using non-bearing wall or sliding doors; whereas foreign apartments had a flexible space by separating the support elements and the infill elements. There was found to be a close relationship between the location of support elements and the variability of unit plans. Support elements can be placed largely into three locations: (1) Between the front side bay and the rear side bay, (2) in the center bay of a unit plan, and (3) others. Depending on the location of support elements, various types of flexible unit plans can be created. Through a comparative analysis of domestic and foreign apartments, basic data that can be used for developing various flexible unit plans was derived.

Purpose: Various policies to reduce the energy consumption have been carried out to save Earth environment against global warming and environmental pollution in many countries. Energy consumption of buildings in Korea has reached 24% of total energy consumption, and energy consumption of apartment has been continuously increasing. Therefore, Korea government has executed building energy efficiency rating certification system to control energy consumption of buildings. Method: This study was conducted to evaluate the energy performance of apartment unit plans according to the increasement of front width of unit plans, and tried to present the basic data to design more energy conscious unit plans for apartments. For the study, three shapes of unit plans -the 2Bay, 3Bay and 4bay unit- were selected for imput models. They were simulated using ECO2 software to assess building energy efficiency rating certification in Korea. Result: According to the results, in cases that balcony windows were not installed, the primary energy consumption of the 3Bay and 4Bay units were less than 2Bay unit, respectively, 0.1% and 2,5%. The primary energy consumption of the 3Bay and 4Bay units, in cases that balcony windows were installed, was less than 2Bay unit, respectively, 1.7% and 3.2%.

This research is the survey result of the retirement house in Ochiai area that is a famous as mountain village of Japan. This area is being formed in a steep slope and be arranged the building long a side along the contour line. As for the plan type of a main house 'the middle bedroom three-madori(bay) type' and 'the parallel two madori(bay) type' occupy many. As for in the retirement custom of Ochiai area the independence family style (separation/ separate meal/separate household economy) is a principle and a parents family builds the retirement house and move out. The plan. of the retirement house is two-room type of 'Omote(public room) and Uchi(kitchen and living room)' and agree with the plane prototype 'plan constitution of a necessary minimum' of farmhouse of this area. The reconstruction that the retirement house is remodeled handily with a main home, especially intend the convenience of the life such as a kitchen and toilet has been done. The retirement custom has been succeeded thoroughly until recent years in this area. However, this traditional custom is seeing the end, without there is the successor of a main house with depopulation.

The three-dimensional eco-hydrodynamic model was applied to estimate the physical process in terms of COD (chemical oxygen demand) and net supply(or decomposition) rate of COD in Kamak Bay to find proper management plan for oxygen demanding organic matters. The estimation results of the physical process in terms of COD showed that transportation of COD is dominant in surface level while accumulation of COD is dominant in bottom level. In the case of surface level, the net supply rate of COD was 0 -0.50 mg/m2/day. The net decomposition rate of COD was 0 -0.04 mg/m2/day in middle level(3 -6m) and 0.05 -0.1 5 mg/m2/day in bottom level(6m -bottom). These results indicates that the biological decomposition and physical accumulation of COD are occurred predominantly at the northern part of bottom level. Therefore, it is important to consider both allochthonous and autochthonous oxygen demanding organic matters in the region.

The three-dimensional eco-hydrodynamic model was applied to estimate the physical process in terms of nutrients and net uptake(or regeneration) rate of nutrients in Kamak Bay for scenario analysis to find proper management plan. The estimation results of the physical process in terms of nutrients shelved that transportation of nutrients is dominant in surface level while accumulation of nutrients is dominant in bottom level. In the case of dissolved inorganic nitrogen, the results showed that the net uptake rate was 0∼60 mg/㎡/day in surface level(0∼3m), and the net regeneration rate was 0.0∼10.0 mg/㎡/day in middle level(3∼6m) and above 10mg/㎡/day in bottom level(6m∼below). In the case of dissolved inorganic phosphorus, the net uptake rate was 0.0∼3.0 mg/㎡/day in surface level, and the net regeneration rate was 0.5∼1.5 mg/㎡/day in middle level and 1.0∼3.0 mg/㎡/day in bottom level. These results indicates that net uptake and transport of nutrients are occurred predominantly at the surface level and the net generation and accumulation are dominant at bottom level. Therefore, it is important to consider the re-supplement of nutrients due to regeneration of bottom water.

This study was conducted to select the location of the logistics center for environment-friendly agricultural products in the Gwangyang Bay Area. AHP(Analytic Hierarchy Process) technique was used to examine location selection factors and factor hierarchy was made through a questionnaire survey and an expert interview for objective and quantitative decision. The hierarchy process of location factors of logistics center for environment-friendly agricultural products in the Gwangyang Bay Area were categorized into five factors such as natural factors, economic factors, social factors, distribution efficiency, and land use plan. Then, those factors were sub-categorized into three factors each. As a result of pair-wise comparison analysis of five categories, the weight of economic factors was the highest, and easy cargo transportation, fitness to higher-order plan, climate, land price, and limitation regulations of sub-categorized factors appeared as comparative evaluation criteria. The priority of the final candidate was decided through this process. While the weight of the Yulchon II Industrial Complex was the highest in natural and economic factors were the highest, the weight of the Gwangyang Hwanggeum Industrial Complex was the highest in social factors, distribution efficiency, and land use plan. The result of the final analysis showed that the Gwangyang Hwanggeum Industrial Complex was the most optimal location candidate for the logistics center for environment-friendly agricultural products.
