Restaurant is a settign for est and social intercousrse fo rpeople in the cities, and is essential to provide its users with pleasant and comfort space. Color is used as a design tool which has most powerful effect to change the nature of a space and atmosphere, As a basic study for desirable environmental color for restaurant, this is studied mainly on the following discussion points. 1) Inportance of environmental color and its role in accordance with space characteristics as restaurant. 2) The psychological effects of color in the clinetes, color conditioning of the dining ares, problem of change in the appearance of color in the selection of materials and color harmony of total environments. 3) Prior to color planning in detail , the nature and characteristics each restaurant contains and their correlation with various locational , physical , social environmental , human variables have been analyzed. And the total atmosphere of the dining area as a place where the clients finally stay has been dealt with various visual , environmental and functional problems of color about fixed elements such as the wall. the floor, the ceiling and semifixed elements such as tables, chairs, etc.

The purpose of this study was to grasp actual condition of remodeling elements by specialists' in-depth interviews. The interview has been conducted to interior designer who have a wide experience of apartment remodeling. In-depth interview is a kind of qualitative method in which attention to reply of responses with open-access between interviewer and respondents. According to the results, remodeling elements were generally the renovation of balcony into the livingroom or children room, removal a doorsill, installation of storage furniture, change of lighting fixtures in the all rooms and change equipments of bathroom. Finishing materials were usual used normal wallpaper and normal or low emitting adhesive on ceiling and wall, tempered-flooring on floor, and ceramic tiles on bottom and wall of bath and entrance.

One of the big difference between Aalto and other modem architects lies in an attitude that Aalto went beyond the principle of dogmatic functionalism. As an architect of Northern Europe, Aalto made unique architecture that showed both the language of modem architecture and vernacular architecture. He presented the best example which showed modernity in architecture without losing the meaning of the context including site, region and cultural tradition. With this background, Aalto developed his own typological design approach. As Wolfsburg church was designed in his prime of time, it showed the origin and evolutionary process of religious architecture as well as general features of Aalto's design. Clustered site plan, dynamic space of interior, the adequate control of natural light are representative characteristics found in Aalto's religious architecture. Wolfsburg church also demonstrate these features in more specific way including the continuity of wall and ceiling that showed spatial dynamics, free opening of wall which reflects on functions, and careful adjust of natural light. As a result, Aalto showed his typological design strategy that added new design ideas to the accumulated design vocabularies in the design of Wolfsburg church.

This paper presents a navigation method for a mobile robot which can follow a path drawn on a monitor screen. The current position and heading direction of the mobile robot are obtained using a single camera from a single image of the guide mark projected on a convex mirror. This proposed method eliminates the need to rotate or tilt the camera to track the guide mark, because the convex mirror and a stationary camera provide a panoramic view of the surrounding area. As guide marks, fluorescent lamps on the ceiling, door frames, or any other natural line segment can be used without adding any artificial elements to them.

Chemical application is very hazardous in confined spaces under the canopy ceiling in Korean vineyard. For a small orchard sprayer adaptable to such a working condition, a low-cost autonomous steering control system was developed using two ultrasonic sensors, two electrically-operated cylinders and 80196kc microprocessor. A distance ranging system timed the round-trip for each ultrasonic wave to travel against parallel targets, placed every 1.5m spacing along both sides of a desired path. A steering control algorithm of the autonomous operation began with ranging left and right targets and the heading was decided using difference between the distances. Electrically-operated cylinders actuated steering clutches to guide the sprayer. Evaluation tests showed that the orchard sprayer could travel within RMS value of 5cm along the desired path. Ground speed did not affect the performance of the autonomous guidance system at the speed ranges of 0.29~0.52m/sec.

사회활동을 왕성히 펼치는 여성들이 흔히 쓰는 말 중에‘유리천장(glass ceiling)’이라는 말이 있다. 위를 쳐다보면 한 없이 올라갈 수 있을 것같지만 막상 그 곳에 다다르면 보이지 않는 장벽이 머리를 누른다는 뜻이다. 법이나 규정상으로는 평등이 이루어진 것처럼 보이나‘실제상황’은 그렇지 않음을 의미하는 자조적인 말이다. 특히 국내에서 회사를 경영하는 여성CEO라면 누구나‘유리천장’의 도를 넘어‘콘크리트 천장’, 혹은 이보다 더한‘강철천장’을 실감하게 된다. 그러나 이런 사회적인 편견과 제도적인 불평등 속에서도 자신만의 확고한 입지와 영역을 구축하며 벤처를 이끄는 당당한 여성CEO가 점점 늘고 있다. 서버판매 및 서버호스팅, VPN 등 사업으로 성장일로를 걷고 있는 e-Business 전문업체인 씨앤에스 김태희(46) 대표가 그 대표적인 우먼파워에 속한다. 김 대표는 지난해‘제6회 여성경제인의 날’을 맞아 모범여성기업으로 선정되어‘대통령 표창’을 수상하는 등 여성기업분야 우수중소기업으로 탄탄한 기술력과 탁월한 경영능력을 인정받고 있다. 뿐만 아니라 그는 IT업계의 성공 키워드인 기술과 경영, 마케팅의 삼박자를 고루 갖춘 전문 경영인으로도 유명하다.

FastSLAM is a factored solution to SLAM problem using a Rao-Blackwellized particle filter. In this paper, we propose a practical FastSLAM implementation method using an infrared camera for indoor environments. The infrared camera is equipped on a Pioneer3 robot and looks upward direction to the ceiling which has infrared tags with the same height. The infrared tags are detected with theinfrared camera as measurements, and the Nearest Neighbor method is used to solve the unknown data association problem. The global map is successfully built and the robot pose is predicted in real time by the FastSLAM2.0 algorithm. The experiment result shows the accuracy and robustness of the proposed method in practical indoor environment.

In this paper, we propose a real-time people tracking system with multiple CCD cameras for security inside the building. To achieve this goal, we present a method for 3D walking human tracking based on the IMPRESARIO framework incorporating cascaded classifiers into hypothesis evaluation. The efficiency of adaptive selection of cascaded classifiers has been also presented. The camera is mounted from the ceiling of the laboratory so that the image data of the passing people are fully overlapped. The implemented system recognizes people movement along various directions. To track people even when their images are partially overlapped, the proposed system estimates and tracks a bounding box enclosing each person in the tracking region. The approximated convex hull of each individual in the tracking area is obtained to provide more accurate tracking information. We have shown the improvement of reliability for likelihood calculation by using cascaded classifiers. Experimental results show that the proposed method can smoothly and effectively detect and track walking humans through environments such as dense forests.

The purpose of this study was to improve the lighting environment of the VDT workspaces in computer laboratory. This study was carried out through the field measurements on the computer laboratory and a survey using the questionnaire about the VDT workspaces. The major findings of the study were as follows: (1) It was unbalanced among the illumination, luminance, and color distributions in the the VDT workspaces. (2) The difference of brightness between the CRT screen and its surroundings have presented on the whole unbalanced. (3) It was proved that the artificial light source of the ceiling lighting should use the parabolic louver luminaire limiting the radiant luminance.

Deterioration of the educational facilities built before 1985 is a serious situation. The purpose of this study is to present the efficient remodeling method of old educational facilities. This paper, part III, presents the systemic and synthetic judgment method of deterioration grade of finished materials. Evaluation of the deterioration is carried out in every eight classrooms or building elements divided by the use. And classrooms are divided by several parts for example floor, wall and ceiling etc.. The whole deterioration of the building judges the result of every part collectively.
