This study was carried out to obtain basic data for architectural plans about factors on the facilities relocation needed in management of variation type. For this, floor plans of thirteen middle schools located in Korea and Japan were compared. The results showed a successful conversion to block system according to each subject after remodeling in the schools of our country, however, a monotonous spacial composition excluded other spaces such as media space, teachers' station and preparation room was also shown. These mentioned spaces were important factors in the investigated schools of Japan. By the results of the spacial composition about each space required to the management of variation type, a space share of supplemental areas for learning activities and movement, had shown comparatively low share before remodeling, was improved to 6% and 11.6%, respectively. However, the spacial share of two areas were 16.8% and 12.9%, respectively, in the schools of Japan and it meant the distribution of area was more even than the cases of our country.

The glymphatic system hypothesis is a concept describing the clearance of waste products from the brain. The term "glymphatic system" combines the glial and lymphatic systems and is typically described as follows. The perivascular space functions as a conduit that drains cerebrospinal fluid (CSF) into the brain parenchyma. CSF guided to the perivascular space around the arteries enters the interstitium of brain tissue via aquaporin-4 water channels to clear waste proteins into the perivascular space around the veins before being drained from the brain. In this review, we introduce the glymphatic system hypothesis and its association with fluid dynamics, sleep, and disease. We also discuss imaging methods to evaluate the glymphatic system.

The purpose of this study is to find out the leisure activity for middle-aged from 45-65 living in the house. The survey had been conducted in 135 respondents with Questionnaire during September 25th to October 7th, 2006. Frequency, Cluster Analysis and Cross tabulation were obtained from the data using SPSS program. The Questionnaire consists of leisure activity and leisure location based on 3 properties of leisure. The results of this study are as follows. First, frequency the respondents is differed by demographic characteristics. Those who have higher level of education, subjective economic power and are younger were more active. Second, the leisure activity in the house is higher in passive on 1st, intellectual and emotional on 2nd, mass media and social activity on 3rd property. Respondents regard home as not a active space but a relax space. Third, the most preferred location in the house for leisure is living-room. Next, master-room and dinning-kichen are. Because of women who spend time more than men in living. Therefore, designing living space for elderly is considered various leisure type of residents.

If the Industrial Revolution had been the first industrial revolution. our 21st century will witness a second industrial Revolution. Namely. we will attest to a revolution whereby we will be freed from brain work by automation systems. computers and artificial intelligence. The technological revolution of the Information society has also resulted in various changes in the area of design. Designers almost depend on the newest computers of advanced functions to drastically reduce the production time. maximize the effects. save the cost and differentiate the design products for a stronger competitiveness. Accordingly. the media of design expression are changing. In short. the design works which had been done on the plane are now being expressed on the three-dimensional cyber space. Thus, this study alms to review the effects. positive and negative. of such a trend on the design.

Light has primary function to enlighten the darkness. However, as development and progresses in media has caused big change in our life, the range of usage and application of light is broadened. And these days, light is actively used as a communication tool in a space. This thesis is based on an idea that a new prospect of light is required and at the same time the theoretical foundation should be established to take active advantage of light. In Chapter two, analysis criteria are established to verify study hypothesis. The applied methodology is to analysis the contents based on literature review. Key words related light in space design are extracted and the frequency of those key words are quantitatively measured. Taking advantage of the result, the characteristics of light are divided into three categories, 'light as symbolic information', 'light as communication medium' and 'light as topological form'. In chapter three, analysis of cases is performed. The cases are selected based on space analyzing criteria established in Chapter two. Qualitative analysis is performed on the cases categorized into natural light and artificial light. Basic analysis elements are evaluated for each case. And each case is allocated to one of three categories, 'light as symbolic information', 'light as communication medium' and 'light as topological form'. Through this analysis, it is found that light in space has prevailing characteristics of 'light as symbolic information' and 'light as communication medium'.

The various kinds of consumption belong to a general category and at the same time the expression of most basic aspiration in the human life. Since the ancient times, the consuming activities have lasted with the other basic activities and the consuming space conducting consumption has developed as physical devices along with the human history. Those companies that have been given attention and getting favorable impression currently being selected by the consumers are now concentrated on the storytelling marketing. The storytelling marketing is that the emotion-oriented marketing activities give consumers the opportunities to enjoy the product contained stories to put the stories to marketing activities. It approaches to consumer with human story emotionally rather than rationally and heart rather than mind. Recently, the architecture has become artistic either it was linked and contacted media or part of marketing. We think that the story telling marketing is the eternal triangle among art, architecture and marketing that is a propensity or movement to interior at this time. I found out that the storytelling marketing methodology is able to touch the consumer's heart and stimulate consumption aspiration that makes new circumstances and experience expressing space. And for that, effective marketing methodology is to give the consumers a more exciting and enjoyable motivation in accord with the modern society to give companies positive image to customers and accordingly for the companies to gain profits. The story telling space that is filled with ideas which produce new circumstance and experience using the established narrative and theme will be required continuously and able to develop in the future.

The purpose of this study analyzes an expression method and a characteristic of transparency of a surface in commercial space, and it is to show an index of a surface design. We did image evaluation by SD method for the commercial space which directed transparency to a surface as the method. We used a factor analysis and cluster analysis to get the image characteristic and type of the expression methods. As a result, we got six following expression methods and design indexes. (1) Transparency expression of a surface by a multiple layer. (2) Transparency expression of a surface by unification with a structure. (3) Transparency expression of a surface by transparency of materials. (4) Transparency expression of a surface by a combination of various materials. (5) Transparency expression of a surface by unification of the image media. (6) Transparency expression of a surface by transparency transformation of materials. We think that it will be able to make use of these results as a design index for the surface design of a commercial space in the future.
