Owing to the mass-housing policies of high-density and high-rise, the residential environments in Korea have come to be uniform and monotonous. Nevertheless, the design competitions introduced for the first time in 1980s have Played significant roles in developing the fresh ideas and concepts in housing design. And in our country, the land of the gradient $0-9^{\circ}$ that is able to plan as level sites come up to 32.5% of the total land and the land of the gradient $10-29^{\circ}$that should be designed by considering the characteristics of the sloping sites is 53.2% of the whole. For that reason, the development of the apartment housing in the sloping site has been done largely to solve the issues associated with the scarcity of the land. Therefore, it is very meaningful job to see the various design methods on the basis of the characteristics of the sites, particularly gradient, by analyzing the prizewinners in the design competitions. In this context, the research analyzed the works that won the design competition after 1990, and organized the types of the block plans and the design characteristics applied in our residence housing. Secondarily, it classified that types by the gradient and analyzed statistically and compared the numerical value.

A distributed video-on-demand (VoD) system is one where collection of video data is located at dispersed sites across a computer network. In a single site environment, a local video server retrieves video data from its local storage device. However, in the setting of a distributed VoD system, when a customer requests a movie from the local server, the server may need to interact with other servers located across the network. In this paper, we present three types of presentation plans that a local server must construct in order to satisfy the customer request. Informally speaking, a presentation plan is a temporally synchronized detailed sequence of steps that the local server must perform for presenting the requested movie to the customer. This involves obtaining commitments from other video servers, obtaining commitments from the network service provider, as well as making commitments of local resources, within the limitations of available bandwidth, available buffer, and customer data consumption rates. Furthermore, for evaluating the goodness of a presentation plan, we introduce two measures of optimality for presentation plans: minimizing wait time for a customer, and minimizing access bandwidth is used. We develop algorithms to compute optimal presentation plans for all three types, and carry out extensive experiments to compare their performance. We have also mathematically proved certain results for the presentation plans that had previously been verified experimentally in the literature.

Recently, the domestic remodeling market is increased in scale. This study is to develop the sanitary piping system which improves quality of life and facility performance when the aged public housing is remodeled. Above all, we found out three standard floor plans in bathrooms of the public housing. And then, the plan and section types of the sanitary piping system were developed for the on-floor piping, a construction cost of each section types was estimated to review the economical fact. Also, the field mock-up test was performed in the type of the pipe shaft with on-floor pit. In result, the developed sanitary piping system was available for the remodeling public housing without a great facility cost. Additionally, the sanitary pipe was replaced easily through the shaft and on-floor fit. And a noise was reduced to a lower unit when the water flowed down.

This study compared evacuation effectiveness between the conventional school auditorium plan and a suggested hypothetical plan that was generated by a mathematical model, which is commonly applied in the field of industrial engineering. Recent school buildings became much more complicated in floor planning due to new social needs and modern curriculum than the old days. Nevertheless, architect's approach to floor composition in terms of fire emergency evacuation planning, still has no relation to optimized effective but relies more on an conventional school planning. Therefore, since school buildings are much more likely to be exposed to any fire related events than any other building types, emergency exit effectiveness based on spatial composition has to be seriously evaluated with a scientific method. The algorithm, which acquires the number of persons in each spatial type(node) per floor and the minimum physical distance between spatial types(arc), can propose the most optimized spatial layout per floor regarding emergency evacuation event. Consequently, this study evaluated school's fire exit effectiveness focusing on auditorium area with the scientific tool and suggested the most reliable spatial layout regarding possibile emergency evacuation event.

The The purpose of this study was to compare of the characteristics of floor plan and housing satisfaction with two types of housing units, 2-bay and 3-bay. Two bay housing unit is one that two rooms, a bedroom and a living room, are in the front side of housing unit, and 3-bay is one that three rooms such as two bedrooms and a living room are in the front side. 15floor 85m$^2$-sized plans of housing unit were analyzed. There were differences in the arrangement of entrance, balcony, and bathrooms between two types of housing units. The subjects were 200 housewife who lived in 2-bay housing unit and 200 ones in 3-bay one. The residents who lived in 3-bay were younger, higher education and income level, and more home ownerships than ones in 2-bay. The residents in 3-bay were more satisfied with their housing unit than in 2-bay.

General hospitals in Korea have increased more in size since 2000, and as not only medical service but the quality of the environment also got important, the considerable changes have appeared revolving around the lobbies. This study is a basic research to find a direction of a plan for general hospital lobbies in response to the demands that change. It was examined the current condition of lobbies so as to derive the idea of types of lobbies and of functional elements, and based on the research, it was compared and analyzed in terms of the spatial configuration to draw the characteristics by type. The result of the research is as follows. (1) The lobbies were explored after being classified into four types; the plan(central type/street type) and the elevation(eclectic type/double-story type). (2) The hall and corridor were ranked high in order of importance in the whole spatial configuration, and it has been utilized in various ways. (3) Also, each type differed with the others in its main functional area, regarding traffic line efficiency and spatial intelligibility.

The main purpose of this research was to examine what were the factors of shopping value that consumers perceived, if there is any difference between male and female, and if male and female consumer group were divided into different groups according to the pursuing shopping value type. Data were solicited from convenience sample of 347 adults(156 male and 191 female) who were between 19 to 49 years of age. Sources for the sample were companies and apartment complexes and several colleges in Seoul and Chonan to diversify by such demographics as age and social status. The statistical methods used for this study are factor analysis and cluster analysis and Scheffe test using a SPSS 10.00 GLM. The main findings are as follows: First, four dimensions of clothing shopping values were identified as pleasure, planned, leisure, and convenience value. For male, it appeared in the order of pleasure, leisure, planned, and convenience shopping value and for female, it appeared in the order of pleasure, planned, leisure, and convenience shopping value. The most important subdimension of clothing shopping value was 'pursuing pleasure' and the least important one was 'convenience' regardless of gender. Second, three types of consumer groups for male & female were identified. For male consumers, it appeared as planned, leisure/convenience, and pleasure pursuing group. For female consumers, it appeared as pleasure, convenience, and leisure shopping pursuing group. Here, pleasure is a common factors to affect shopping itself free from gender, but male does shopping with plan and female with pleasure.

For the office work environmental design, the importance of the design management is increased to improve operation efficiency as well as the aesthetic environmental implementation of the function today. Lighting is a required element ineffective operation environment. It has become more important for the aesthetic, economic, and practical reasons, to consider the luminous environment and the lighting of visual tasks separately. When the brightness is insufficient, productivity deteriorates, and the layout of the lighting located by mistake causes the fatigue of eyes. Productivity rises to office in a large number of studies so as satisfaction is low in general in the dark office, and to be bright. Therefore the purpose of this research is to suggest the right direction of lighting design of office building area. 11newly renovated office buildings are selected for this luminous environment research. We could conclusions as following through this research. First, it was planned brighter than the recommended lighting level in the most space. It shows that the accurate lighting design criteria is needed in order to achieve proper lighting environment. Second, the application of the LED lighting fixtures is continuously increased in the recent office lighting environment. It is explained that it is applied for reasons of the electrical energy reduction and the maintenance efficiency with the long life time. Third, the consideration of the lighting plan for the difference of working types is not enough. with various communication configuration through an independent plan, and the effective lighting plan that appropriateness preparation design and energy saving area vailable must be applied. Fourth, the lighting environment of the lobby needs a specialized lighting plan as are presentative space of the building.
