There is a new demand for functional sharing between existing schools and neighbouring community facilities. This study is to find out the priority of the existing schools at Nowon District for functional sharing development. Most schools are located geographically near the highly populated residential district. The development will be a form of multi-use school complex. The process starts with selecting the schools located in the center of local community. Since the school facilities occupies the relatively enough space, it is possible to expand other functions for the neighbouring communities. Accordingly many citizens can utilize them because of their greater activities. This study is based on the investigation and the analysis of actual situations related to the complex development of school facilities. As a result the suitable candidate schools for the multi-use development are listed under the searched conditions.

The demand for one-room system house as a new type of house will increase gradually, and residents also tend to be diversified. However, a method of planning of planning of one-room system house was limited and unified. Current floor plans of the one-room don't utilize a benefit of open plan in small areas. The purpose of this study is to propose several guidelines for the planning of one-room system houses that correspond to residents' needs in order to facilitate the benefit of open plan such as efficiency and multi-purpose use in small area. For this, a field survey was carried out as case studies, with individual interviews, questionnaires, and actual survey including taking pictures. Subjects were 50 residents who living in one-room system houses in Busan. Space usage behavior of residents, residential satisfactions, and preference attitudes on the attached service facilities were analyzed. The results were synthesized to suggest several guidelines for planning of one-room system house.

WHEN IT IS REQUIRED TO CONNECT OVERHEAD TRANSMISSION LINE WITH UNDERGROUND CABLE, PREVALENT METHOD WAS TO USE CABLE HEAD TYPICALLY MADE OF LATTICE STEEL STRUCTURE. BUT IN VIEW OF THE INCREASING DEMAND THAT STEEL STRUCTURE INSTALLED IN URBAN AREA AND/OR RESIDENTIAL AREA NEED TO MATCH WITH ENVIRONMENTAL SURROUNDINGS, THE UNSHAPELY LARGE-SIZED LATTICE STEEL STRUCTURE CAN NOT BE A PROPER ONE BECAUSE THAT IT IS NOT WELCOMED BY THE RESIDENTS AND ACCORDINGLY ITS INSTALLATION TENDS TO CONFRONT WITH CIVIL PETITION. AS AN ALTERNATIVE METHOD TO SETTLE AFOREMENTIONED UNFAVOURABLE SITUATION WE MAY BE UNDER, WE AR INTENDING TO DEVELOP THE CABLE HEAD MADE OF TAPERED TUBULAR STEEL POLE AND TO PUT IT TO PRACTICAL USE. THE ADVANTAGE WE CAN TAKE OF THE TAPERED TUBULAR STEEL POLE IS THAT IT CAN BE INSTALLED IN A VERY LIMITED SPACE MAXIMIZING THE UTILITY VALUE OF THE LAND AND THAT ITS SMART SHAPE WITH COLOUR COATING IN CONSIDERATION OF AESTHETIC AESTHETIC CAN BE IN GOOD HARMONY WITH THE SURROUNDINGS.

The housing market is now difficult because of excess of the increase rate of housing and long-term recession but high-rise mixed-use buildings can mix residential facilities with various demand facilities focusing and they have the advantages to secure open space and excellent view by high-rise apartment. But there are problems by hindrance of skyline formation and height of buildings. Therefore, the purpose of this study is to suggest the height standard and the slenderness ratio to location types of Mixed-use Residential Tall buildings. For the method of the study, term arrangement through literature search and the precedent research survey were first done, the level of urban design and the details related to the height of buildings were done as the case research focusing on the 16 cases in Seoul. The following results were drawn by suggesting the height standard and the slenderness ratio by location type based on them. First, the height of mixed-use building by location type in the level of urban design gets higher starting from the secondary center of the city and can be suggested as from less than 150m to more than 200m. Second, the slenderness ratio shall be planned as more than 1:3 because the area of the ground level of mixed-use building is large unlike Mixed-use Residential Tall buildings and visual passage shall be placed so that unity of openness and group formation will be planned. Third, for the height related to Mixed-use Residential Tall buildings, amendment of the special architectural district system and the special law related to super high-rise buildings shall be enacted.

In this paper, we selected commuting scenarios in the most congested metropolitan area in Korea, and conducted noise analysis during personal air vehicle (PAV) operation using aviation environmental design tool (AEDT)software which was developed by Federal Aviation Administration (FAA). Noise is the second important factor after safety in order to operate PAVs through concepts such as ODM (on-demand mobility) introduced by National Aeronautics and Space Administration (NASA). Noise analysis were performed by modeling low-noise ePAVs as commercial helicopters and predicted residential suitability in order to resolve problems in which accurate NPD (noise power distance) data from PAVs were not released. The application of noise reduction technology such as electric propulsion has significantly reduced noise exposure levels and has reached the conclusion that commuting with PAVs is feasible without noise problems in the metropolitan area.

Shear wall is commonly used as a lateral force resisting system of concrete mid-rise and high-rise buildings, but it brings challenges in providing relatively large space throughout the building height. For this reason, the structure system where the upper structure with bearing, non-bearing and/or shear walls that sits on top of a transfer plate system supported by widely spaced columns at the lower stories is preferred in some regions, particularly in low to moderate seismic regions in Asia. A thick reinforced concrete (RC) plate has often been used as a transfer system, along with RC transfer girders; however, the RC plate becomes very thick for tall buildings. Applying the post-tensioning (PT) technique to RC plates can effectively reduce the thickness and reinforcement as an economical design method. Currently, a simplified model is used for numerical modeling of PT transfer plate, which does not consider the interaction of the plate and the upper structure. To observe the actual behavior of PT transfer plate under seismic loads, it is necessary to model whole parts of the structure and tendons to precisely include the interaction and the secondary effect of PT tendons in the results. This research evaluated the seismic behavior of shear wall-type residential buildings with PT transfer plates for the condition that PT tendons are included or excluded in the modeling. Three-dimensional finite element models were developed, which includes prestressing tendon elements, and response spectrum analyses were carried out to evaluate seismic forces. Two buildings with flat-shape and L-shape plans were considered, and design forces of shear walls and transfer columns for a system with and without PT tendons were compared. The results showed that, in some cases, excluding PT tendons from the model leads to an unrealistic estimation of the demands for shear walls sit on transfer plate and transfer columns due to excluding the secondary effect of PT tendons. Based on the results, generally, the secondary effect reduces shear force demand and axial-flexural demands of transfer columns but increases the shear force demand of shear walls. The results of this study suggested that, in addition to the effect of PT on the resistance of transfer plate, it is necessary to include PT tendons in the modeling to consider its effect on force demand.
