오늘날 모듈러 건축 방식으로 주거시설에 대한 설계와 건설이 이루어지고 있다. 이러한 모듈러 기반의 주거시설에서는 자유로운 공간의 변형이 필요시 발생하기 때문에 홈 자동화 시스템에 대해서도 새로운 방식의 도입이 필요할 것으로 예상되어진다. 즉 기존의 홈자동화 시스템에서는 사전에 계획된 자동화 설계에 따라 유선 센서들을 기반으로 개발되어지고 있는데 공간의 변화가 이루어지는 모듈러 방식에서는 기존의 고정이면서 유선 방식의 센서 기반의 자동화 시스템은 적합하지 않을 것으로 판단된다. 따라서 모듈러 건축 방식에서는 역동적인 공간 변화에 따라 필요 센서들의 수와 종류가 변화고 센서의 위치도 변화기 때문에 이러한 다양한 변경 요소를 자동적으로 받아들여 홈자동화 시스템을 구축하는 시스템이 필요하다. 따라서 본 논문에서는 모듈러 건축 방식으로 구축된 주거시설에서 센서 인식을 자동으로 할 수 있고, 사용자 인터페이스를 자동으로 생성하여 변화하는 공간에 적응하는 홈자동화 시스템을 연구 개발하였다.

An analysis of elderly behavior at home needs to be meticulously understood in order to build a spatial environment where the elderly can live safe and independent lives. To this end, the following study analyzed elderly behavior that occurs in the home, constructed personas, and developed persona-based scenarios of elderly behavior at home. Persona was composed of behavioral characteristics, spatial characteristics, and personal characteristics (gender, age, disease etc) that have a direct effect on living activities in the home, so it was intended to express a more real persona. The study developed six personas based on the behavioral and mobility characteristics of the elderly, and scenarios for each persona developed bsed on the following eight behaviors: toilet use, bating/Shower, washing and grooming, having meal, sleeping, dressing/undressing, laundering clothes, and getting out of home). Through this, the study determined the characteristics and difficulty level of various sub-behaviors and actions that occur in elderly behaviors at home. It also determined characteristics related to the use of physical elements such as equipment and furniture that are a part of those sub-behaviors. The behavior scenarios developed in this study can be utilized to understand the difficulties involved in elderly behavior, and to present a spatial plan and remodeling direction that alleviates such difficulties. This study is also significant that it investigates the applicability of persona-based scenario method on residential architecture.

Purpose: Many design index that are using in planning phase have been developed. The most popular things among them are Window to Wall Ratio and Surface to Volume Ratio. However there are some limits. Window to Wall Ratio cannot consider building size and Surface to Volume Ratio cannot do Window to Wall Ratio. Accordingly, in this paper, the Window to Floor Ratio was proposed that it can be considered both building size and Window to Wall Ratio. And analyzed correlation of energy demand. Method: For the test, 16 modules with the size of $6m{\times}6m{\times}4m$ were used to make 35 models with the same volume. The simulation was conducted to 945 cases using the window-to-wall ratio of 30, 50 and 70 % in three areas such as Seoul, Gwangju and Jeju and three kinds of windows. And IES_VE was used. Result: The findings above show that the Window to Floor Ratio that can be considered both building size and Window area have to become as design index. It was found out that design criteria with SHGC is necessary, not with the thermal performance (U-value). It is needed to additional analysis about residential building and the effect of 24-hours heating and cooling condition. It plans to carry out research to establish design indicators for climatic conditions in the country and building applications.

An important factor in assessing the beneficial qualities of a city's intersection spaces can be measured by examining a pedestrian's approach to the space and calculating the openness observed in the overall design of adjacent buildings. These spaces are influential, since they offer opportunities for pedestrians to spend time and take in views of the surrounding environment. The intersection of horizontal components in cities such as Bundang-si and Suwon-si can provide a sense of openness or greenness. We believe that there is a need for careful analysis and study of such components, as defined by designations in Bucheon-si research, and that this study can give important insights for future urban planning and design. When assessing the openness of an intersection, a key variable is the reported rate of perforation, which factors into the greenness of a space. Because of the large and varied scope of this research, this rate is highly variable, as there were many differences between each site. In descending order of average ratios: Seongnam-si, 41.79% > Bucheon-si, 35.40% > Suwon-si, 30.42%. The data compared for each city was divided into study sites selected at downtown locations as well as in urban outskirts. Openness and greenness were analyzed at each downtown and outskirt site. A summary of the results shows a decreased openness average of -2.63% in downtown locations versus outskirt. The greenness ratios in urban outskirt areas were 4.86% greater than downtown locations on average. As it relates to the results of this analysis of openness, the comprehensive property zoning for each city was determined as a ratio of residential to commercial designations. This study analyzes view points within urban cross intersections in the downtown landscape. It presents basic data and research directions to promote a better environment with regard to openness, and consists of an analysis of the relationship between a variety of physical components.

In this study, the seismic performance of the connections between L-shaped columns composed of concrete-filled steel tubes (L-CFST columns) and H-beams used in high-rise steel frame structures was investigated. Seven full-scale specimens were tested under quasi-static cyclic loading. The variables studied in the tests included the joint type, the axial compression ratio, the presence of concrete, the width-to-thickness ratio and the internal extension length of the side plates. The hysteretic response, strength degradation, stiffness degradation, ductility, plastic rotation capacity, energy dissipation capacity and the strain distribution were evaluated at different load cycles. The test results indicated that both the corner and exterior joint specimens failed due to local buckling and crack within the beam flange adjacent to the end of the side plates. However, the failure modes of the interior joint specimens primarily included local buckling and crack at the end plates and curved corners of the beam flange. A design method was proposed for the flexural capacity of the end plate connection in the interior joint. Good agreement was observed between the theoretical and test results of both the yield and ultimate flexural capacity of the end plate connection.

This study is for the Kyungduk-Dan(as a altar of Milsung-Daegun) and The Manun-Jae the characteristics(lay out and planning, window patterns, structure, materials) of the the Korean traditional house during the modern era. Before Manun-Jae was used for the house. The Kyungduck-Dan was constructed in August according to the Lunar Calender in 1927. The Manun-Jae(house for Ki-hun Kang, millionaire ) was completed in 1924. Modern Architectures brought to Korea with the bricks, the tiles, the flash doors, the plate grasses, the brass hardwares. These architectural material was used in positive. During the construction of Manun-Jae in 1924, it happened the architectural exchage among a korean, a chinese and a japanese constructor. Though using the air exhaust valve at the kitchen of Ukyung-Kak( old Anchae), it could be assume that the modern convenience and the improvement of residential environments was considered at that period during the construction of Manun-Jae. That construction was elected with the brick($222mm{\times}106mm{\times}50mm$), the chinese colored tile and plate glass such a modem materials. The new shape of the korean lattice window and the wooden flash-door with glass was used. In Ukyung-Kak, the Chan-Maru(service space) and the kitchen such as a service space or concise utility zone was organically connected. Especially, considered the domesitic activity and circulation, the western kitchen sink and the Chan-Maru(service space) was rationally placed. At the Manun-Jae and the Kyungduck-Dan, the architectural characteristic is that the new shape of windows was used. The lattice window at the Ondol room of Ukyung-Kak, was rgadually added the plate glass and the wood plate. The lattice window with the grid shape at kitchen of that building was adapted japanese grid lattice window in korea at that period. It is the sample that korean traditional house was typically influenced from the japanese resident culture. The Manun-Jae and the Kyungduck-Dan as the modern house kept the form of korean traditional architecture, and was partially adapted a modern characteristic space and modern architectural materials. During the japanese occupancy, these residence can be showed the transition in formally.

Nowdays the apartment is a main type of modernized residential buildings. According to the improvement of construction techniques and functions of windows and doors, recent apartments are enhanced air tightness of windows, doors and building envelopes. As Infiltration is decreased and natural ventilation is reduced, energy could be saved in winter. However, indoor air quality is bad. The air Infiltration of a building could be enlarged by physical actions, such as building designs, constructions and reduction of air tightness which is caused by aging. This research analyzes and measures with KNS-4000P (Sapporo air tightness measurement) the air tightness of the high rise apartments which is recently constructed and not occupied yet. With depressurization method, the KNS-4000 installed on the window and the indoor air-leakage was measured. At that time, Air come out from the edge of the windows and doors because of the pressure differences between indoor and outdoor. We measure the amount of the air as effective air leakage areas. This method of depressurization takes less time to measure than other methods and is less affected from other conditions. We measured infiltration of total 56 household, 29 households S apartment (total floor area : $64.42m^2$) in Balan and 29 households D apartment(total floor area : $78.21m^2$) in Chonan. As a result of the field measurements at October 2003, normalized leakage area of D apartment in Cheonan was $2.05cm^2/m^2{\sim}3.49cm^2/m^2$ (average: $2.77cm^2/m^2$) and normalized leakage area of S apartment in Balan is $1.23cm^2/m^2{\sim}1.68cm^2/m^2$ (average: $1.5cm^2/m^2$).
