본 연구에서는 급기가압에 따른 건축물 내부의 공기유동에 대한 수치해석을 수행하고 거실, 부속실 및 계단실 간의 차압분포 및 유동 특성을 분석하였다. 유동 해석은 유효누설면적을 측정하기 위해 제작된 누기율 시험설비에 대하여 수행하였으며, 급기가압에 따른 각 실의 압력 및 유속분포 등을 분석하였다. 본 해석에서 공기의 누설은 유효누설면적을 갖는 얇은 틈새를 방화문과 창문에 위치시키는 방법으로 모사하였다. 이러한 방법을 이용한 해석은 계단실과 부속실 간의 차압에 대한 기존 실험의 결과를 적절히 예측하였다. 해석 결과를 통해 국부적인 누설이 급기가압 제연 설비의 전체적인 유동 패턴 및 압력 분포에 큰 영향을 미치지 않음을 확인하였다. 거실-부속실 문 단면에서의 평균속도가 방연풍속에 대한 국가화재안전기준을 만족하였으나 문의 상부와 같은 국부적인 위치에서 부속실로의 유출이 발생할 수 있음을 확인하였다.

The Educational Cultural Center for Students is a new mixed-cultural space which made around 1997 for students' education of humanism and talent with the 7th revision of educational course. This Educational Cultural Center for Students is different to the existing one because the subject of the culture is students who make creation and performance by themselves while the former ones were for seeing, hearing and feeling things. There are seven Educational Cultural Center for Students all over the country and will be built more in the future. Comparing to the former Educational Cultural Centers for Students, functional rooms in the Educational Cultural Centers for Students are an outdoor performance room, a large performance room, a small performance room of performance facility, a gallery of display facility, a gymnasium, a swimming pool, a fitness room, a table-tennis room of physical facility, a library and a reading room of a book facility, and a group room, a computer room, a singing room, a billiard room, an art room, a musical room, a dancing room, a manner room, a playing room, a cultural lecture room and a seminar room of a interest-activity facility. The result of analyzing the usage frequency is that a performance room has the highest frequency and a display room, a musical room, a music appreciation room and a physical room follow the frequency order. But this frequency does not fit for all area. By place and social situations, the frequency and space organization may be changed.

For those with disabilities, the residential area is the primary place to adapt the disabilities. Since the quality of the area gives a critical impact on their quality of life, it is essential to finding the measures to create the residential environment that supports their independence. In this regard, this study aimed to compare and analyze the interior elements of the houses that hinder the independence of the physically handicapped in the rural and urban areas, and conducted a survey on a total of 80 physically challenged in Seoul and Yeongwol (40 for each area). As a result, the respondents answered that the houses where they are currently living are hindering their independence regardless of area, and there were regional differences in the level of inconvenience with the size of living room, size of utility room, location of room, lighting and heating environment, ventilation system, deteriorated wallpapers and finishing materials, threshold and floor level difference and humidity control. This study has significance by providing the realistic measures to improve the housing environment of the physically challenged living in the rural and urban areas to be customized to them to increase their quality of life.

Green compressive strength, permeability, deformation, flowability, compactability and green hardness values at room temperature are dependable on the grain distribution and grain shape. The results obtained under constant moisture (4% for sand) and bentonite (8% for sand) were as follows; 1. With decreasing grain size, surface area of sand grain was increased. 2. With decreasing grain size, coefficient of angularity was increased. 3. As surface area increased from $8926.43cm^2$ to $21211.16cm^2$ , green compressive strength was increased from $210.93\;g/cm^2$ to $449.98\;g/cm^2$, hardness was increased from 76.7 to 82.3, but permeability was decreased from $411.7\;{\frac{\;cc\;{\cdot}\;cm\;}{atm\;{\cdot}\;cm^2\;{\cdot}\;min.}}$ to $113.7\;{\frac{\;cc\;{\cdot}\;mm\;}{atm\;{\cdot}\;cm^2\;{\cdot}\;min.}}$ 4. As surface area increased from $8926.43\;cm^2$ to $21211.16\;cm^2$, flowability was decreased from 82.3% to 80.8%, deformation was decreased from $67.1\;cm\;{\times}\;10^{-3}$ to $54.6\;cm\;{\times}\;10^{-3}$, but compactability was increased from 44.8% to 54.3%. 5. Room temperature properties of molding sand were affected by variation of surface area.

This research aims to establish the size standard of university library's user space, and present the standard and method to calculate total area required in the planning of new building construction and remodeling. Nine university libraries newly constructed or remodeled since 2000 were selected among the libraries of large scale universities with more than 10,000 enrolled students as the target libraries in this research. The target libraries were classified into A group (five cases partially remodeled) and B group (four cases newly constructed or fully remodeled) on the basis of the change of times. A university library can be divided into three spaces (user space, administration space and public space). This research classified the reading room in the user space into bookshelf zone, reading zone, information/office zone and hall/other zone, and analyzed area ratio according to each zone. B group's bookshelf zone decreased 12% more than A group, and B group's reading zone increased 10% more than A group. However, there was no big change in the area ratio of information/office zone and hall/other zone. This can be interpreted that university library changes from book and archive preservation-oriented space to user-oriented space. This research presented a proper reading room area calculation method, based on the capacity of books, by reflecting such a change. Each zone's standard was set up through classification of domestic and international standards, based on which, the calculation method of university library's total floor area required was presented. The reason why there was difference in university library's total floor area required according to domestic standard and international standard was that the number of enrolled students per seat in the reading room was different. The area calculation methods presented in this research can be utilized as useful data upon planning university library construction or remodeling.

Steady state turbulent airflow and unsteady characteristics of generation, transportation, and recovery behavior of contaminate particles in the simplified 2 dimensional Vertical Laminar Flow (VLF) type clean room was numerically simulated using the low Reynolds number k-over bar.epsilon- turbulent model. Characteristics of airflow in VLF type clean room are greatly affected by the recirculation zone around working surface. The recirculation zone must be considered at the time of clean room design because the recirculation zone whose area increases with increment of inlet velocity exerts bad influence upon the performance of clean room in terms of particle contamination. The location of maximum particle concentration changes from the location of particle source to the recirculation zone, while averaged particle concentration is reduced exponentially with time. Recovery time of clean room with spontaneous particle generation source is inversely proportional to inlet velocity. We introduce nondimensionalized recovery time through the dimensional analysis, which can indicates the general performance of clean room with design structure change. It was identified that .tau. is independent of inlet velocity and background concentration. Therefore .tau. can be the simple factor to compare the different structure of clean room in terms of dynamic response to contamination and becomes larger with better structure of clean room.

This study aims to examine and classify plane types of Hanok at Haengbok village, analyze changes, area distribution and space structures of space components and sort plane types and their characteristics. Plane types were divided into four; living room, kitchen, dining room, etc. These plane types were labelled as LK type, L+K type, L+DK type and LDK type. LK type and L+K type were mainly found at single-wing house and made of living room and kitchen centered space structure, but substantially they were designed to ensure guest room, room and living room. Therefore, hanok built at Haengbok village were designed to combine the functions of residential function and lodging. Plane type was preferred to be used for double functions of residence and lodging. On the other side, L+DK type and LDK type were mainly found in house with several wings and they were designed centering around living room for family space. In addition entrance was placed to simplify entry from the outside and each room and guest room were arranged to be accessed from living room. It means that the functions of house focused on residence rather than lodging and all rooms had the structure to be used as residential space in case of emergency.

Purpose: It is important to plan the ward module at a time when the size of beds, the floor area, and the construction budget are all set prior to the hospital design. In this context this study aims (1) to derive various factors affecting the ward module, and (2) to analyze the appropriate room module according to the type. Methods: Design factors related to hospital modules are derived through precedential studies, and the types of ward elevation are classified by reviewing the drawings of 18 case hospitals. And the detailed dimensions and area of the derived elements are analyzed. Results: The X-axis modules of the ward are switched to long span structural columns of 9.9 m, 12.6 m and 13.2 m, but the ward modules still represent 6.6 m. The Y-axis module of the ward shows a dimension of 9 to 9.9m in the process of changing a multi-person room into a four-person room. Type A of curtain wall with columns located on the wall of the room and type B of curtain wall located in the center of the room are analyzed due to their variations. The square window type, which forms the elevation of the square window by exposing the columns to the elevation, and the outframe type, which protrudes from the structural columns and beams, have elevation designs limited. There are, however, no obstacles to the interior space of the hospital room, so the wall composition and furniture arrangement are expected to be free. The ward area of Curtain Wall Type A, which can secure an effective area of 5.9m*5.0m, are 52.1m². The Curtain Wall Type A, Square window type, and the outframe type are 49.8m². Implications: As part of the hospital standard module plan for economical and reasonable hospital building planning, a type was proposed in this study in conjunction with the external design. It is hoped that it be a base for standard module research linked together to the Central Treatment department, Outpatient department and underground parking lot.
