Though Korea and China have a lot of things in common, these two countries have developed different housing style. However, after modernization, apartments have become major housing style in both Korea and China. So this research analyzed 240 apartment plans which was build in Seoul and Beijing in 2000s and 2010s to predict the future trends for apartments. The results are as follows: The opening direction of the front door will be outwards as the hallway space of small apartments in China become wider as the living standards is increasing. Because of the floor sitting lifestyle, Koreans end outdoor activities when take off their shoes at the entrance hall and continue for indoor activities, they separate entrance hall from livingroom. However, because Chinese have chair sitting lifestyle, entrance hall and livingroom is not divided. Korean apartment shows a trend which connects livingroom, diningroom and kitchen altogether; however, Chinese apartment shows a trend which separates kitchen from livingroom and diningroom. Bedrooms are showing a trend of distributed layout. Master bedroom are showing a trend which includes separate bathroom or attached room as the size of apartment increases and so on.

The purpose of this study was to find out the physical change of the farm house and its anbang(the main room : master bed room), to identify the behavioral changes : activity and awareness of anbang, and to clarify the relationship between the physical changes of the farm house, and the behavioral changes of housing life-style in the anbang space. Bibliographical studies, cultural approaches and field survey method with questionnaire were used to collect data from 55 residents of Anwhari and Yangkyori in Pyong Teck Koon. Tables and drawings were made to analyze the data. The major findings were 1) the heating system of the ondol anbang. The most popular type is the double heating system(new pipes added to the traditional ondol). This combination ondol system brought some conviniences to the farmers. This change in structure of the ondol were of four types : Complete change in style, enlarged-completely changed style, partially changed style, enlarged-partially changed style. 2) from 1960 through 1970 lighting of the anbang changed room oil lamp to electricity. 3) the finishing material of the anbang floor changed from traditional oil paper and straw mats to vinyl flooring. 4) Traditional furniture and small decor items are gradually disappearing and are being replaced by modern items. 5) The awareness and actual use of the ondol anbang has not much changed from the multi-functional and sacred space of daily living : which are the characteristics of Korean traditional ondol anbang. The biggest consistency in the ondol anbang is the heating system of the floor, which is the characteristic of ondol culture in Korea. This system will continue regardless of time and place in Korea.

The purpose of the study is to evaluate the Rural Settlement Development(RSD) driven by government in historical view, and its effects on the facilities and houses of rural village in the country. Through the study, we have come to the results that the major concerns of the RSD projects since 1950s has been transferred to as following. First, the reformation of inter-facility; dressing room, kitchen, bath-house, etc of rural houses, from that of outer facility; roof, fence and etc. Secondly, the substantial objects of the projects of village settlement improvement have been changed from partial reformation of individual houses, public facilities, etc early, to comprehensive reformation by master plan for village settlement recently.

The purpose of this study is to perform the post occupancy evaluation in apartment housing with the dining room and kitchen(DK) facing the front side, and then to compare them with findings in unit plan facing the back side. A questionnaire survey method was used in this study. These questionnaires were administered, along with an interview, of 200 households in the apartment of 27-28 pyoung($76.50-78.54\textrm{m}^2$), in Gwangju city. Those living in an apartment with DK facing the front side tend to be less satisfied with the physical feature factors. expecially for layout of rooms, location of second bedroom and master bedroom, size and location of storage spaces, and location and size of balcony than those with the DK facing the back side.

In this paper, we consider the development methodology of wireless monitoring system for a distribution transformer. The master/ slave devices are installed in the power distribution feeder and measure the current state of pole or ground transformers. After measuring, the devices send the measurement data to operating room through the wireless network such as RF and CDMA so that the power distribution supervisor can prevent a distribution transformer damaging caused by overloads and imbalance of loads.

This paper deals with the free cooling system of express bus using natural energy source in order to improve the room air quality and save cooling energy. In an express bus, there are may passengers in unit area, requiring the improvement of air quality and giving higher energy saving efficiency. Particularly, the express buses running fast make it easy to take in outdoor air at a flow rate controllable with a damper mechanism. This paper proposes the analysis on the air flow achieved by a damper controlled vertically and horizontally in order not to deteriorate the ride comfort of the passengers.

The purpose of this study was to identify the Korean traditional housing design characteristics in apartment model houses. 37 floor plans of apartment model houses in Busan were collected and analyzed. Also, 31 design element check-lists were checked through the field study in apartment model houses. The results were as follows: 1) Korean traditional housing design characteristics in aspects of space organization, such as harmony with nature, hierarchy, focal space, flexibility, were founded in apartment houses. 2) Korean traditional housing design characteristics in aspects of scale, material, color, and motif were mostly founded in the master bedroom and the living room in apartment house. 3) Also, the larger the size of apartment houses were, the more Korean traditional housing design characteristics were founded.

Environmental qualification (EQ) for safety-related equipment is required to ensure that those equipment will perform their required function even under the harsh environment conditions arising from design basis accident in the nuclear power plant. As a part of EQ program, the room temperature analysis in case of a loss of Heating, Ventilation, and Air Conditioning(HVAC) system was carried out to ensure the operability of the safety-related equipment of a nuclear power plant randomly chosen among the Korean nuclear power plants. In this paper, this analysis was performed in the conservative perspective using GOTHIC code. The room temperature analysis includes selecting the rooms in which the safety related equipment are located but not supported by safety related HVAC and determining the temperature of the selected rooms. Target rooms for the analysis consist of W229/W237 (Aux. feedwater pump room), W232 (Aux. feedwater tank room) and W230 (Equipment passageway). The results showed the temperature range from $43^{\circ}C$ to $83^{\circ}C$, in 72 hours after a loss of HVAC. Those values are far below of generic EQ temperature($171^{\circ}C$). Therefore, it is satisfied with EQ requirement of temperature limits on safety related equipment.
