The purpose of this study is to analyze consumer's lifestyle, needs and preferences and design trends for planning of the future apartment interior design. Recently, social change such as computerization, industrialization, pluralism and globalization has been braught lots of changes to modern housing spaces. The meaning of ‘Family’ and ‘Residence’ has been diversified by various life-style of modern family. Therefore, the new concept of residence is needed to change for the future housing plans and satisfy their sophisticated needs and preferences considering modern family's lifestyle and life-span. This research was conducted through the questionaire-survey, taste style survey by show card, and focus group interview(F.G.I) for investigating consumer's life style and tastes. Through this research, four-types of consumer's lifestyle were classified by analyzing data and special spaces such as family-room, media room, interior planted-space, and men's room were needed to consider interior space planning. This study shows that the planning of storage space, flexible space, livingroom and multi-used space will be more important in apartment interior space.

Nowadays, kitchen are not for the housewives who were independent themselves in the past but for the functional spaces. Kitchen spaces are not only the main function in the residence but also changing spaces which provide the mutual understanding communication between the family members. Although the primary function of the kitchen is food preparation, it is commonly a gathering spot for family and friends, especially if it includes an informal eating area. With so much time spent in the kitchen, and can easily become tired do the decorating scheme. But, for fear of high remodeling costs, it is often unchanged for many years. Surprisingly, there are many changes that can de made to the decorating scheme of a kitchen without either the expense or the inconvenience of remodeling. Between materials on the market, materials for kitchen interior were chosen for this study. Following results came from the materials after combustion. Among boards, MDF showed the highest score in these four categories; residual inflame time, residual glow time, carbonization length, carbonization area. Also, among finishing materials (interior materials), MDF + Poly Coating showed the highest score in those categories. Therefore, it seemed that interior materials need flame retardancy.

This study aims to determine adolescents' emotional response and preferences for varying interior designs of learning spaces available at community facilities in apartment across Seoul. In particular, the subjects have been fragmented by gender and age for comparative analysis of emotional responses across different demographics of adolescents. A survey on the preferred designs of learning spaces in community facilities revealed that 'elegant,' 'cheerful,' and 'temperate' are the three main emotional words selected for image tool development. Emotional assessment verified the validity of these terms. Between the two genders, adolescent males preferred 'temperate' images more while adolescent females preferred 'cheerful.' In terms of the design of learning space, adolescent females deemed the interior atmosphere and area space to be the most important factors, while adolescent males pointed to the color of furniture and lighting to be the most important. Such results imply that there is a clear difference of emotional response between adolescent males and females. The results also imply that different atmospheres and design priorities must be considered when designing gender-specific spaces.

Edward Hopper is one of the great American artists in the 20th Century. In the field of art, it seems that his paintings are thoroughly analyzed In terms of human alienation and emotional aspects in various ways. However, in his numerous paintings, highly interesting spatial aspects can be found. Purpose of this study is to analyze some of his painting by the spatially analytical tools to examine how his space is experienced. The tools are: relationship between each space, relationship between light and space, and geometrical composition. Among many paintings by Hopper, four of the works that depicted interior spaces are selected and further case-studied in detail: ${\ulcorner}$Rooms by the Sea${\lrcorner}$ (1951), ${\ulcorner}$Sun in an Empty Room${\lrcorner}$ (1963), ${\ulcorner}$New York Movie${\lrcorner}$ (1939) and ${\ulcorner}$Automat${\lrcorner}$ (1927). An Environmental Simulation with scale models was used to examine the relation between light and space. After the research, some unique characteristics of his space were found. Even though his paintings seem to represent the everyday spaces, there are fascinating hidden structure to make people experience in a specific way that Hopper created. Spaces In his paintings do not communicate with each other but are constantly interrupted by the element of time. The mundane everyday world is rediscovered and recreated through these multidimensional and heterogeneous space.

In contemporary times, "environmental designers" need to consider both exterior and interior aspects because of the growing trend in dissolution between exterior and interior spaces. To quantify "spatial sense" which serves as the standard for environmental design, this study has asked 63 subjects to evaluate 15 interior and 14 exterior spaces. The "spaciousness (small-large)", "openness(closed-open)", "warmness(warm-cold)", "brightness(bright-dark)", "softness(soft-hard)", "spatial intimacy" and "frequency of visit" were adopted as variables of spatial sense. Through the analysis of these variables, this study could gain the difference between spatial sense for exterior and interior environments, quantify the spatial sense that physically and psychologically appropriates to human beings. The result of this study can be summarized as follows: Twice the amount of spaciousness was observed between the interior and exterior spaces. And the standard on intimate space is established with W/H ratio of 5.71 and high Window/Wall Area ratio in the interior and an area of 3,800m2 and a W/H ratio of 5.57 in exterior. The difference between the spatial sense in the interior and exterior space is mostly dependent on the psychological sense. The increase of physical size caused by the interior space to be perceived as cold, dark and hard psychologically, but exterior space to be perceived as warm, bright and soft. Psychological senses, especially softness, affect spatial intimacy to the greatest extent among the given variables. As the psychological senses for interior spaces were largely independent from the given space's size and perceptive senses, the size of the interior space, which exhibited spatial intimacy, could not be deduced. In comparison to this, due to the high dependency between the psychological senses for exterior spaces and the given space's size and perceptive senses. The study also showed that interior and exterior spaces have relatively different spatial sense and physical standards. Such research results are predicted to provide applicable standards for environmental designers for exterior and interior spaces in the future.

The study was intended to evaluate common spaces of office building in view point of universal design. The common spaces were access road, main entrance, parking lot, corridor, and restroom. Two office buildings in Centum city of Busan were evaluated by their workers, each 100 ones. The check list for evaluating them consisted of 36 universal design elements which related to five common spaces. First, there were many universal design elements which need to be improved. Second, among five common spaces, restroom has the most elements to be rated low. First of all, at least one restroom for wheelchair should be provided each floor. Third, even though both of two office buildings were recently built, there were significant difference between their users' evaluations. This implies that the concept of universal design is not applied to office buildings well. Fourth, there were significant difference among users' evaluations according to age, especially in case of design related elements. This means that users' age is an important factor to be considered.

Daylighting is one of the major elements in architectural design. It also plays an important role in the museums focused on displaying artistic works. Many architects have tried to predict daylighting performances in exhibition spaces during the design process of museums. The aims of this study are to present the design methods using the computer program RADIANCE that is available for the evaluations of daylighting performances in indoor space and to help architects design daylighting systems for better exhibition spaces of museums. For this study, Seoul Museum of Art was chosen and it was evaluated the recommended illuminance and the impacts of direct sunlight under the conditions of overcast sky and clear sky with sun. According to simulation results, they indicated that the alternative toplight system(sawtooth shape) was more effective for daylighting of exhibition spaces than the existing toplight system(pyramid shape) and this study showed a method to evaluate daylighting effects in exhibition spaces with various shapes of toplight systems.
