The purpose of this study is to find out the changes on the metropolitan condominium apartment unit plans based on the interior spaces related to women such An-bang (master bedroom), bathroom and attached spaces to the master bedroom, living room, diningroom, kitchen, utility room, and balcony. This study used the content analysis method and space syntax. Contents were limited to the floor plans with 3 rooms type and about 105 m2 in the Korean apartment encyclopedia. The unit plans of 2,278, built from October 1975 to January 2008, were analyzed and basically SPSS package 16.0 was employed. The results were as followed. 1) Living room was a core space and an increasing tendency. After 2001, the design trend of living room connected with kitchen and dining room, and dining room changed into one space combining with women's working space such kitchen. It meaned women's working activities became into family public activities as to depending open access. 2) Kitchen had a characteristics that was connected to utility room or back balcony, and the number of extra kitchen increased. Also, the size of DK decreased, but utility size little increased. It was showed the characteristic of this space was still for women. 3) An-bang had a little strong characteristics of married coulpe or women's personal space with bathroom or dress room/powder room. 4) In addition, the values of integration and control of living room and DK were highest. It meant these space were centered in unit plans. Next, the An-bang and dress room/powder room were high. Utility room or balcony's were next, and these were women's working space. Therefore, family's public space was most important, and married couple or women's personal and working space were later in planning.

The residential environment is a place which reflects the gradual evolution of human consciousness because it is a cultural space the term, 'houses' is not relevant in this context as it literally means 'contains'. The long history of human living habits cannot be 'contained' within a space, but can be 'expressed' by a space and by the way the space is used. Furthermore, due to the way it is typically constructed, the basic characteristics of the house usually cannot be rapidly changed to accommodate new habits. However, recent changes that have taken place to the characteristics of the traditional master room suggest that traditional societal values associated with patriarchy have diminished. The current trend where priority is given to children's education also affects such a change. Existing researches related to the master room is confined to the behavioral use of the space and the composition of the physical space, while research on the master room its plane type has not been carried out. Therefore, in this study, apartment model houses are selected, and are classified according to the types of master room. An analysis is then carried out of the master room based on the occupants' requirements in terms of consciousness. Any planning modifications where required are then suggested. This research comprises the followings stages. First, an examination is carried out of existing research on the master room in order to understand its background and spatial components. A definitiones of related terms is also provided. Second, an analysis is carried out of the model houses exhibited at Suwan District, examining the typical standard that has been selected for the master room. Third, an analysis is conducted of the topics and questions to be selected for a questionnaire. Fourth, an analysis is carried out of the consciousness, satisfaction and requirements of the residents, as respondents in the questionnaire, related to the master room. and Research is then conducted of the architectural methods for planning the master room. Finally, future countermeasures for planning the master room are described based on the above analysis and research findings.

In this study, the reverberation characteristics of coupled spaces were investigated using a scale model. Two rooms were connected through an acoustically transparent opening known as an aperture. The acoustic characteristics of the coupled room by varying three parameters, the aperture opening size, the absorption ratio between the two rooms and the locations of the secondary room, were measured and analysed. The results indicated that a reverberant secondary room, produced large variations of the acoustics in the main room and an absorptive secondary room was effective to provide systematic control of the acoustics in the main room. The reverberant secondary room should be located at the rear of the stage and the aperture opening ratio over 6.25% produced large variations of the acoustics in the main room. However, the aperture opening ratio over 25% had no effect on variations of the acoustics in the main room. The absorptive secondary room should be located at the rear of the audience areas and the aperture opening ratio over 3.13% produced large variations of the acoustics in the main room.

This study is designed to measure the indoor environment and research on the environmental situation in the lecture room where the lecture is conducted during the winter time in order to understand the level of environment in the lecture room and then suggest the method of improving the environment in the lecture room in the future. The findings are as follows. First, the number of ventilation measured at Lecture Room 1 was 1.2 times/hour while that at Lecture Room 2 was 2.2 times/hour. Second, the lighting at Lecture Room 1 and 2 was 650~700 lux while the noise at Lecture Room 1 and 2 was not more than 60dB. Third, Group 1 and Group 2 felt in the same way that the air quality in the lecture room was not good when the air quality was measured in 30 minutes after the start of lecture. Fourth, both Group 1 and Group 2 showed the lowered concentration on the class in 30 minutes after the start of the class when the room was heated. But Group 1 got less drop in the concentration when they was put in the non-heated room. Fifth, As for the change in the carbon dioxide volume during lecture, the carbon dioxide volume in the room where the windows was closed rose 1,000~1,400ppm from that at the time of start, thus showing that the indoor air quality got worsened. In addition, it is hard to control the indoor temperature due to the heating and non-heating. Accordingly, it is necessary to get the heating system which can make the ventilation in order to keep the environmental level in the lecture room to a certain level and keep the proper indoor temperature.

In this study, the effect of the air purifier located in the living room on the reduction of PM_2.5 concentration in the living room and bedroom was investigated. Measurements were carried out in real-life for about 2 weeks in a Korean apartment building where a 3-person household had lived and the exclusive private area was 84.9 m². When the air purifier in the living room was operating, the change in PM_2.5 concentration was measured when the door to the bedroom connected to the living room was opened and closed. In the case of living with the bedroom door open, the average PM_2.5 concentrations in the living room and bedroom were almost the same. When living with the bedroom door closed, the average PM_2.5 in the living room was higher than in the bedroom. The ventilation and cooking effects in the living room mainly affected the PM_2.5 concentration in the living room. Only one air purifier in the living room was able to keep the PM_2.5 concentration in the living room and bedroom low.

As the noise of ship engine room is too loud, the engineer who works in a ship engine-room has the trouble of hearing. In this paper deals the investigation of the noise of ship engine room and cabins with the internationally allowable noise exposure level and noise exposure time. Recently, the problem of engine-room noise is more serious because of shipowner wants to make small number and larger size of cylinder. Therefore, engineers work in a ship engine-room for a long time have the trouble of hearing when they are exposed the high noise level. In this study, two kinds of vessels were used to investigate the noise of engine room, engine-control room, bridge, offices and cabins. As criteria of sound levels, A-weighted sound pressure level and octave band pressure level were used.

This thesis analyzed arrangement and mixture method of function elements, which are getting more important in museum planning. It used quantitative method, Space Syntax and Visibility Graph Analysis tool to analyze five case museums. Through this analysis, advantages and disadvantages of two methods were derived and case museums' arrangement and mixture attributes were grasped. Results of the analysis were derived differently by two kinds of plan form which were room to room type and open type. Open typed museum recorded similar graphs of Integration, Visual Integration and Visual Connectivity. Since whole space structures were relatively simple and structure of exhibition halls were opened, the results of Space Syntax and Visibility Graph Analysis had similar graphs. Room to room typed museum showed differences in Integration, Visual Integration and Visual Connectivity. In the result, the most accessible space was lobby and Mediation Space became the center of visibility. Also, the exhibition hall, where the opening of room to room typed exhibition hall was penetrated visually, became a center of visibility. Lobby space, which was close to entrance, had the highest Visibility Connectivity. As Space Syntax could analyze the museum as whole space structure, Space Syntax showed strength in room to room typed museum analysis compared to open typed museum analysis which has relatively simple structure. Visibility Graph Analysis could expect the flow of exhibit distance including visibility analysis unlike the flow of exhibit distance with space arrangement. The exhibition hall, which secures the sight to penetration of an opening, couldn't be analyzed in existing Space Syntax. However, it became the biggest advantages in Visibility Graph Analysis of room to room typed museum. Visibility Graph Analysis derived detailed results in exhibit arrangement so it will be the useful method not only for architecture but also for planning of exhibit arrangement in open typed museum. Through this study, various possibilities on Quantitative Analysis Method of Museum Architecture could be verified. However, the analysis still has limitation of second dimension. Therefore, diverse and liberal following study will be expected to accomplish.
