The main purpose of this paper is to provide useful infonnation for residential site design in Korea by analyzing Japanese case. The important characteristics of Japanese design techniques are follows. First, the characteristics of residential site development can be expressed as "eco-friendly" and "public order". The patterns of spatial use also focuses on living environment improvement. Second, variety replaces unity in internal mobility plans. For example the width of street, size of park are not same in a site boundary. Third, to avoid street parking and commodity exhibition, commercial buildings are set-back and public parking lot is constructed. Fourth, fences of private house are made of trees rather than bricks. It connects green environment between internal and external space of houses.nal space of houses.

For the pleasant dwelling place, the most of apartments are designed with the increased green area ratio in ground space and the underground parking lot. However, the condensation in underground space has occasionally occurred due to the insufficient ventilation and insulation treatment. Despite reinforcement of the insulation treatment and mechanical ventilation for the preventing method of condensation. It seems difficult to expect preventing effects for the condensation without consideration of the thermal characteristic of structures. Furthermore, no fundamental measure has been established because maintenance work for these defects incurs a lot of costs and these defects could be occurred again. This study suggests a new method for preventing floor surface condensation through analyzing the reasons of condensation which occurred in the underground floor.

According to the change of the life environment and economic growth, the more highly a city has developed, the more concentrated is the urban function. That is, a city is required for adding more infrastructure. But, both limited land resources and financial problems made it impossible to add infrastructure. So, the necessity of multi-dimensional planning of urban infrastructure was recognized. Especially, in the urban residential area, a mixed-use of the playground of a school and the empty space of a park is desired to serve the issue of insufficient parking spaces. Schools and parks are closely connected to the center of a town, and playing a central role for the town life. For this reason, they are highly demanded in urban residential areas and also expected to be effective. However, we need to consider not only parking convenience but also the safety of users in design process, because people using parks and schools include young students and the elderly. In this study, we mainly examined physical characteristics and the utilization of schools and parks with parking facilities in urban residential areas. Then, we analyzed cases through comparing and evaluating in terms of convenience and safety. and weighed up advantages and disadvantages of each through the comparison of the schools and the parks having parking facilities. The results of this study are expected to provide fundamental references for preparing design standards for such facilities.

In this study, we developed the inverter system to control Induction motor for the vertically circulation parking facility. In the case of calling a pallet, a car parking space, we basically stoned conventional system's problems, pallet is uncontrollable to the fixed position and braking system was worn by forcer braking with remaining speed. Also, by appling to converter controller, added to power regenerative control function, we confirmed the reduce of power supply capacity and the energy saving effect according to increasing operation frequency. The validity of this system is verified by 55kw induction motor driving system. Via this study, the proposed system shows the efficient use of parking facility and good operation characteristics by implementing position and speed control effectively on condition of load and shows energy saying effect by power factor control for the vertically circulation parking facility operation.

This study aims to investigate the change in building density and residential environment after the reconstruction of decrepit public rental housing complexes formed in accordance with the Land Readjustment Project during the 1970s-80s. The results of this study can be summarized as follows: First, in terms of change in residential environment after the reconstruction, floor plans that were limited to two to four types and to small apartments measuring $42.9m^2$(13py)-$56.1m^2$ (17py) became varied, presenting 5-6 types of floor plans and various sizes of apartments. In particular, the reconstructed apartments were mainly built in a size smaller than 85($m^2$) and in the 3LDK floor plan and staircase-style unit architectural structure in order to reflect the lifestyle of residents. Second, in terms of change in building density after the reconstruction, the building coverage ratio did not change a lot, but the floor area ratio showed great change depending on the complex, ranging from a minimum of 2.9 times (Singdong Complex) to a maximum of 5.4 times (Eoyangdong Complex). Such change is attributable to the reconstruction policy that aims to improve the residential environment for original residents, secure economic feasibility and efficiency, and reflect the lifestyle of residents while incorporating dividends assigned to the existing housing project members as well as the maximum floor area ratio allowed by the regulation. Additionally, in terms of change in the number of floors and building density after the reconstruction, the former 5-story apartments were changed to apartments with 16-28 stories. Accordingly, the number of households in each complex has also increased by 20%. Third, according to the characteristics of parking facilities in terms of the size and density of parking spaces, former apartment complexes had only aboveground parking lots, not underground parking area. The newly constructed apartment complexes have underground parking space, and the parking-housing ratio is 1.1-1.3 cars.

This study was conducted to analyze the relationship between the types of fiber and its content and the levels of airborne fiber concentrations at eight parking lots where sprayed insulation material was found on the walls and ceilings. Also this study was designed to find the relationship between the levels of airborne fiber concentrations and such variables as air current, humidity, total exhaust volume, surface condition of insulation material and building age. The results obtained were as follows : 1. No significant correlation was found between the levels of airborne tiber concentration and the building age, air current, humidity, total exhaust volume, space and the number of traffics. 2. A significant correlation was found between the levels of airborne fiber concentration and the MMMF content of the insulation material(r=0.7594). However, no significant correlation was found between the levels of airborne fiber concentration and total fiber content of insulation material. 3. The differences of the airborne fiber concentrations among Cateogory 1, 2 and 3 classified by the degrees of surface insulation material maintenance were very significant. 4. Two bulk samples contained 30% crodicolite and 1% anthophylite. The MMMFs, in all parking lots, included mineral wool, cellulose fiber, trace cellulose fiber, trace tiber glass and vermiculite. 5. The mean value and the range of airborne fiber concentrations at 8 parking lots were $0.0239{\pm}0.0095f/cc$ and 0.0054-0.0447 f/cc, respectively. The fiber concentrations of 35 out of 38 samples(92%) were over 0.01 f/cc which is the Environment Administration's recommended asbestos level for the underground space. This study suggests that most of building insulation materials used in Korea, contain MMMF and sometimes asbestos. Currently, MMMF pollution levels may exceed the Environment Administration's recommended level for underground space. It has been found that airborne fiber concentrations increased significantly with MMMF content and with the maintenance condition of surface material. Therefore, it is recommended that a proper management technique should be developed and immediately implemented since the conditions of surface material will be gradually deteriorated due to building age and usage. Since health hazards of the MMMF, similar to those of asbestos, are being gradually acknowledged, a proper management technique which is applicable to control total airborne fiber concentrations, both asbestos and MMMF, be developed and an acceptable indoor air standard be promulgated as early as possible.
