As a series of 'Performance Assessment of Building Envelopes I: Double Skin Facade', three types (interior, exterior, mixed (int.&ext.)) of lightshelves and RetroLux were examined in terms of $CO_2$ emissions. It is shown that the exterior lightshelf could achieve the most energy savings (9.6-38.7%) in general office buildings due to blocking solar radiation before entering the indoor space. However, the interior lightshelf is the worst (1.4-5.2%) among three of them. The RetroLux has two components: (1) sun-reflector (first louver component), (2) light shelf for improving daylight induction (second louver component). Due to these two components, solar radiation from windows is filtered depending on seasonal variation (solar altitude). Therefore, the RetroLux can reduce 18.0-27.9% of annual energy consumption (both cooling and heating), and $552-3,290Won/m^2{\cdot}yr$ of operation cost is saved.

The various attempts is made to solve the energy and environment problems. In addition, people interested in their life quality want the more eco-friendly living space. So we suggested that the earth-sheltered house could be one of the eco-friendly and low energy consuming houses to meet the social interest. And we also made data for design of the earth-sheltered house to be applicable to climate of Korea. In this study, a simulation was performed to estimate a boundary temperature according to earth sheltering thickness at the earth-sheltered part(exterior wall) in the case of earth sheltering on the plane ground not using a sloped site. And we analyzed the reduction of a thermal load by using this boundary temperature. We also compared a case of earth sheltering at the vertical wall with a case of earth sheltering at the roof to know the thermal reduction effect of a case of earth sheltering at the vertical wall.

This study shows the present conditions and the appraisal of Public-Toilet in ammusement park of Kangwon-Do. The areas of Public-Toilets are various from over $30m^2\;to\;230m^2$ and the construction costs are also various. The exterior designs aim at Provincial characteristics, traditional images, or modem minimal styles. The floor plans are usually symmetric forms by rectangular or circular spaces. There are some laws and manuals from related association to regulate Public-Toilet. By appraising with these laws and manuals we can notice that there are many problems to improve in Public-Toilet. As the survey, we can find that the unpreparedness of the cognition equipment about whether someone uses the public-toilet has most frequency in related laws. And by the laws about multipurpose toilet, the insufficiency of the accessing space to the chamber pot has most frequency. By the manual of related association, there are much more indications - for example, the unpreparedness of wind protection room or etiquette bell, so on - than by related laws. For the improvement of the culture In Public-Toilet, we should not only improve the related laws, but also activate the deliberation about the appropriate planning in Public-Toilet.

The purpose of this study is to analyze the general patterns of the floor plans and space of Usonian house which designed by Frank Lloyd Wright. this thesis can be summarized as follows : 1) F.L.Wright's houses mostly used simple geometric shapes as the basis for most of his architectural designs. In his early works, his typical floor plans were square or rectangular shapes, which gradually were transformed into various kinds of shape to make the adjustment of location of the site and shape. 2) The general patterns of floor plans of his U-houses were L-shaped or straight shaped using a $4{\times}4$ grid system. Most of U-houses consisted of 3 space: living room, workspace(Kitchen) & dining, and bedroom. Among them, a workspace worked as core role in each house. 3) Even though solid wall is the opposite concept of the transparent glass but most U-houses were designed to have solid walls on one side to provide a gallery space(to secure habitability of resident) and transparent glass walls used on the other side to connect between interior space and natural space of exterior. 4) The cantilever have not been used before Usonian house but F.L.Wright used it which take charge of functions as transfer space between inside space and outside space. 5) F.L.Wright saw the nature as a truth, so he thought the interior space would be natural and all houses must be able to adjust to the natural environment.

The concept of food and beverage space in modern society is changing into complex space where various experiences are provided. With the increase of food service brands, those brands are getting standardized. Providing more differentiated experience and service became an element of competition to companies. The flagship stores among stores presented by companies have much influence on promotion and sales. Thus, it would be necessary to provide integrated service by adopting service design process for the differentiated design of such experiential space. The objective of this study is to examine the satisfaction of service design of food and beverage flagship stores. By creating a checklist to evaluate the space through the theoretical consideration of flagship stores and service design, the satisfaction of service design of food and beverage flagship stores was analyzed. Through the survey with users of the case space, it was possible to check the satisfaction of the service design elements applied to the food and beverage flagship store space. The satisfaction with service design was evaluated through the 5point scale. When the average point was high, the satisfaction with service design elements was high. In the results of the analysis, regarding the spatial composition of flagship stores, the overall interior/exterior atmosphere should contain the image of the company. As flagship stores compose space that can express various event space and company itself on top of the space for sales, they should present the spatial composition differentiated from other general commercial spaces. The significance of a study on service design of flagship stores is to show positive effect on flagship store space. In the future, it would be necessary to have comparative analysis on domestic and foreign cases applied with the service design process, and also to analyze the strategies in the aspect of service design.

Purpose of this thesis is to find out the relationship among the amount of change and the visual cognition, and the visual preference which people like and can feel. Through the investigation of relationships between the amount of change, which indicates the degree of visual variation and the visual preference, the amount of change and the visual cognition, and the visual preference and the visual cognition, basic design data will be supplied, which can satisfy users' desire as much as possible in the most economic way. In order to investigate the relationship between the visually produced the amount of change and preferences, graphic simulation, in which variables other than the visual change are controlled, has been proceeded. Graphic factors of the visual change in the cyber exterior space are determined on the point of location (base plane, vertical plane, overhead plane), shape, size and color. As for the relationship between the amount of change and the preference, only the size is effective. since preferences on the location, shape and color are individual preferences, no common trend can be found. Therefore, we cannot say that which shape or color is better, Since the location, shape and color are qualitative change and the size is the quantitative change, the size can be the measurable change quantity. The relationship between the amount of change of size and the degree of preference is found to be inverse U-shape, i.e., as the amount of change of size increases the degree of preference first increases and, after a certain level, decreases. The same result has been obtained in photo simulation.

본 연구에서는 STOP 위성의 CCT(Computer Compatible Tape) 데이타를 이용하여 수치표고모델을 생성하는 기술을 개발하므로써, 광역에 대한 수치표고모델을 경제적이고 효율적으로 작성하는 방안을 제시하였다. 경사관측된 한 쌍의 SPOT 수치데이타를 이용하여 표고를 추출하기 위해서는 먼저 관측당시의 위성의 외부표정요소(위성의 위치 및 자세)를 결정하여야 하며, 이것을 위하여 번들조정법을 적용하였다. SPOT 데이타는 항공사진과는 달리 다중 중심투영이므로 외부표정요소에 대하여 라인의 함수형태로 모델링을 하였다. 입체 수치데이타에서 동일점을 찾기 위하여 표준상관계수매칭 기법을 적용하였으며, SPOT 위성데이타에 적합한 기준영역의 크기(매칭사이즈)를 결정하기 위한 실험 결과 13$\times$13의 크기가 적절하였다. 동일점을 자동매칭 기법으로 찾은 후, 외부표정요소를 이용한 공간교차(space intersection) 이론으로 각 점마다의 지상좌표를 결정하였다. 이와 함께 이상표고들을 소거하는 알고리즘을 개발 적용한 결과 상당히 효과적이었으며 수치표고모델의 정확도를 향상시킬 수 있었다.

본 연구에서는 저가의 INS와 GPS 정보를 합성하여 고기동 환경에서 항체의 위치와 자세정보를 연속적으로 제공할 수 있는 약결합 방식의 통합 알고리즘을 구현하였고, 4S-Van에 장착된 이미지 센서의 위치와 자세결정 방법에 사용하였다. (D)GPS/INS 통합을 실시하기 전 IMU의 초기 정렬과정에서 방위각은 두 대의 GPS를 통해 결정하였으며 칼만 필터를 이용한 정밀정렬을 수행하였다. 통합 알고리즘의 성능평가를 위해 차량 테스트와 시뮬레이션 테스트를 병행하였다. 통합 결과 차량 시험을 기준으로 나타난 위치 오차는 직선도로에서 l0cm 내외의 정확도를 보이며 자세오차의 경우 시뮬레이션을 기준으로 롤각은 $0^{\circ}.01$, 피치각은 $0^{\circ}.03$, 요각은 $0^{\circ}.1$ 내외의 정확도를 보였다. 구현된 (D)GPS/INS 알고리즘은 기하보정 방법을 통해 이미지센서의 위치와 자세정보 제공자로서 활용될 수 있다. 따라서 4S-Van에 장착된 이미지 센서의 영상획득 시각에 대한 기하학적인 정보를 통해 지상의 건물이나 도로 시설물 등에 대한 3차원 공간 자료 구축이 가능하다고 보며, 구축된 정보를 통해 기존의 수치지도 갱신, 도로 시설물 관리, 비디오 GIS 데이터 베이스 구축 등에 대한 공간 자료 연계 및 응용에 활용할 계획이다.

This study focused on the composition of the exterior space of Parkjinsagoga, the types of gardens and planting and the landscape characteristics of walls, and examined its meaning as modern garden remains. Parkjinsagoga is a modern Korean house that harmonizes traditionality and practicality, and is an invaluable material for research not only on architecture but also on changes in the gardens of upper-class gardens. Its exterior space can be divided largely into An-chae (inner house), Outer Sarang-chae (outer house) and Inner Sarang-chae areas, and a garden was created in each yard (inner garden). In particular, one thing noticeable is that the yard of Inner Sarang-chae, unlike traditional gardening styles, was actively decorated. At the center of the yard of Inner Sarang-chae, two atypical planters and artificial moundings were created and the traffic line of the garden was designed to enjoy them while walking. An atypical pond was created on one of the artificial moundings and trees and shrubs were densely planted. Natural stones were also placed. The style seemed to be affected by Japanese gardens. These characteristics observed in the gardens of Parkjinsagoga are closely related to the transitional characteristics that traditional gardens started to show in modern times. A total of 35 families and 57 species were planted in the gardens of Parkjinsagoga and there were 19 species of tall trees, 20 species of shrubs and 17 species of flowering plants. The number of species planted in the garden of Inner Sarang-chae was the highest, and a total of 22 species of tall trees and shrubs. The walls in Parkjinsagoga were basically earth and rock-fill walls but their materials and patterns differed depending on the type of spaces. Four types of walls were found to be introduced to the house.
