This paper aims to investigate the design characteristics of a single housing block which is increasing in urban areas. For the analysis, all cases of single block housing in Daejeon metropolitan city were gathered into a database. Main concerns were on the location and the physical characteristics. The results of this study were as follows; 1) single block housing has been increasing both in the new developed areas and the existing urban areas 2) their location has shifted from residential districts to semi-residential and commercial districts. For this reason, the size and density has been increasing 3) the slab block with the hall type and the exterior corridor type were general in residential districts, diverse ones, however, including the point tower type were increasing with unusual circulation types such as central corridor, central core, double corridor, and mixed type in semi-residential and commercial districts 4) there were 5 types of access systems, and especially the street access and the piloti access were increasing, which were related with the high density.

Purpose: The courtyard in the ward can light and ventilate in the central space and corridor of the ward. It is possible to improve the disadvantages of the existing double-corridor ward. Also, there is the advantage in that patients are able to contact with nature indoors and cause positive activities. So, the purpose of this study is quantitatively analyze the floor area and the average distance of nurse working of the courtyard in ward. Methods: The subjects are converted through the same criteria setting. And it investigate and analyze the influence of the courtyard in the ward through the analysis of the spatial composition. Result: The factors that affected the floor area increase are the planning courtyard, the corridor type and the dispersion of the medical rooms. The average distance of nurse working is more influenced by the nursing management system of the hospital than by the courtyard. So, It can improve according to the position and number of nurse station. Implications: It can be used as a primary data for courtyard plan in the ward for positive patient environment plan considering the floor area, average distance of nurse working.

One of the most important elements in creating the pleasant residential environment is the wind. For the pleasant residential environment, it is important that the air pollutants are not stagnant but appropriately and swiftly diffused and removed by winds. Especially, the river becomes a main route of wind in the urban core. So, it is necessary to secure the space to circulate the sufficient cool air to this area. But, recently many high-rise apartment complexes have been built along the rivers that have the fine view and pleasant environment. As a result, the cool and fresh air coming from mountains hardly diffuses into the urban core but just flows along the river. Considering the facts above, this study selected types of building layout and kind of land cover as complex or architectural design factors that have an influence on wind environment. Based on the factors, it analyzed change in wind environment according to apartment complex development aiming at the Sinchun area which is Daegu Metropolitan City's main wind corridor. Therefore, when apartment complex development is planned in the future, it can offer basic data for establishing plans for more pleasant complexes. As a result of the analysis, it was shown that the layout type of housing and the building height plan in consideration of wind corridor around the river were pretty effective in increasing the wind speed and circulating the air in the apartment complex. Therefore, if wind corridor is considered when apartment complex development is planed in the future, this study can offer useful information contributing to improve comfort in residential environment in the level of complex building as well as city planning.

In order to solve urban transportation problems, the various alternatives are presented to the public transportation system but the master plan of construction and operation is that there is no validity. PRT unlike other public transport system, is a new transport system that can respond appropriately, to solve the traffic demand, environmental and energy problems. Meanwhile, national and international PRT system was not commercially and the actual construction and operation of the PRT in case of base research is not well established. In this paper, PRT concept was established as the new transportation system, the target area(Nan-gok area) was selected to examine the feasibility of PRT systems and the corridor analysis method has been developed to predict the PRT demand as a basic material of planning process.

Fragility curves show the probability of a system reaching a limit state as a function of some measure of seismic intensity. To obtain fragility curves of six and twelve story staggered wall structures with middle corridor, incremental dynamic analyses were carried out using twenty two pairs of earthquake records, and their failure probabilities for various intensity of seismic load were investigated. The performances of staggered wall structures with added columns along the central corridor and the structures with their first story walls replaced by columns were compared with those of the regular staggered wall structures. Based on the analysis results it was concluded that staggered wall structures with central columns have the largest safety margin for the same level of seismic load.

In this study, the experimental measurements from a one-way moving experiment showed that the average movement speed was 0.55 m/s with an average crowd density of $2.36P/m^2$ in a corridor. The cCalculation result of the correlations between the crowd density and movement speed from the SFPE Handbook showed an average of 0.53 m/s. The difference between the calculation and experiment was 0.02 m/s. A comparison of each data set showed that the maximum difference was 0.38 m/s. Some experimental results showed that the crowd density increased with increasing movement speed and the average data from the entire experiment time was used for the analysis. When the short time interval for frame by frame analysis for video files was conducted, the experimental data was expected to be more reliable.

The purpose of this study is to attain basic source for spacial re-organization of the elementary school. This is the first step of some series of the study, For purpose, some investigations is to grasp the change of education system, curriculum and the present condition of institution were done, and some questions on the using condition of space, the satisfaction and the hope for the space of their school were asked to 371 teachers in elementary school, by questionnaire and interview methods. The result of the survey was analyzed using a statistics-analysis program SAS. The results are summarized as follows: 1) Corridor is using to extend of learning and living space. 2) To correspond to open education, various comers are placed in the classroom and the corridor. 3) As the change of educational system, teachers need parting the source center and the teacher's room.

A tilt-rotor aircraft has various flight modes : helicopter, airplane, and conversion. Each of flight mode has unique and nonlinear flight characteristics. Therefore the gain schedules for whole flight envelope are required for effective flight performance. This paper proposes collective, flap, and nacelle angle scheduler for whole flight envelope of the Smart UAV(Unmanned Air Vehicle) based on CAMRAD(Comprehensive Analytical Model of Rotorcraft Aerodynamics and Dynamics) II analysis results. The scheduler designs are improved so that the pitch attitude angle of helicopter mode was minimized. The range of scheduler are reduced inside of engine performance limits. The conversion corridor and rotor governor are suggested also.

Medical institution has changed into specialized spaces for patients. In particular, women's hospital is the most noticeable change among the medical institutions. The purpose of this study is to provide a basic interior design data through the analysis of case study. For this purpose this study has analyzed of 4 women's hospital built in Seoul since 2000. Especially, environment of ward, resting room, and corridor are analyzed. The results of this study are as follows : Ward needs lighting and room conditioning system which is adjustable for each patient. One-side corridor and alcove-style resting rooms are suitable for patients in general.
