This study started by examining 24 newly-built elementary schools in Sejong City with regard to their present conditions of in-between space. After categorizing the space according to its spatial composition, 5 schools were selected and analyzed in relation to the current status and frequency of use of their in-between space. Among the (other schools, the analysis gave the following results: 1) There was much higher usage of the in-between space for rest/play than for learning, which suggested that more rest/play area and apparatus should be provided. 2) Piloti areas were preferred, and a greater number of activities took place in these places than in the adjoining open areas. 3) When the in-between space was combined with a passage (as in the case of E2 and E3), a separation must be provided in order not to interfere with the rest/play activities. 4) In planning the in-between space, priority should be given to activities over landscape purposes. 5) Diverse and easy access to the space must be planned, particularly as the main entrance is not directly connected to the space. Entry at the end of an adjacent building could be a possible solution.

Due to the Korean government's renewable energy support policy such as the renewable energy utilization building certificate and enlarging the compulsory ratio of investment on the public building, the rooftop photovoltaic projects are expanding rapidly. It is very important for the rooftop photovoltaic projects to analyze the shading effect of the adjacent structures or own facilities. But, the photovoltaic arrangements are planned by the experience of the designers or simple graphic tools. The purpose of this study is to build the process model for optimizing of rooftop photovoltaic arrangement based on three-dimensional geo-spatial information.

Purchasing activity of current market is the way that consumers purchase goods that see for themselves or use the Internet. The consumer want to put the good especially such as furniture in where they want to place. As a result, consumer need to improve the quality of life and meet the consumer's needs that pre-positioned goods and can view this information using the becoming popular smart device. Therefore, in this study, developing smart device applications using augmented reality, thereby propose a new way of buying in changing to smart society.

Among the protected horticulture facilities in Korea, 99.2% are pipe-framed green houses and most of them are structurally vulnerable single-span type green houses. This study examined peak external pressure coefficient for the roof surface of a green house group composed of single-span and a multiple-span green houses. According to the results of the experiment, the distribution of peak external pressure coefficient was around 30% higher in the single-span greenhouse than in the multi-span ones. The external pressure coefficient for the roof surface of the vinyl house group was, in all of the three vinyl houses, was around 20%-30% higher than that for single-span greenhouses.

The purpose of this study is to investigate the unique contrasting landscape characteristics of imperial tombs of Qing dynasty by examining the characteristics of facility layout in which location, Feng shui, and siblings are harmonized with the 12 Qing Dynasty Hwanggyeongchim. Through literature surveys, field observation and interviews, videos and drawing comparison, and inductive contrast analysis, the contrasting landscape characteristics of imperial tombs in the Qing Dynasty were analyzed by classifying them into natural environment, location, Feng shui, and formal esthetics. As a result, the characteristics of the location type and the layout plan of the Qing dynasty imperial tombs were derived from the analysis of Feng shui shape, axis extension distance along the midaxial line, the width of the ridge, the formality of the facility layout according to the difference between the height of the starting point and the end point, the leftward direction of the tomb, and the space ratio of the 'entry space' - 'ritual space' - 'burial mound space', etc. In addition, it was possible to derive the facility arrangement characteristics of tombstones through the analysis of the types and the arrangement order of tombs facilities, as well as the distribution, quantity and types of stone figures, while also revealing some contrasting characteristics different from those of the Ming Dynasty. In addition, it was confirmed that the spatial division effect through the water system and the view effect of the view from the midaxial line and the vista are the representative view effect found in the Qing Dynasty imperial tombs along with the density contrast.

광명시 경륜 경기장은 국민 체육진흥공단에서 턴키(Turn key)공사로 발주하였고, CS구조+공간건축+대우건설, 삼성건설, 태영건설의 제출안이 당선되어 현재 시공중에 있다. 경기장의 저층부는 PC로 설계되었고, 지붕은 철골 트러스를 사용한 Dome 형상으로 이루어져 있다. 돔 지붕의 개념은 지붕에 물을 부었을 때 가장 흘러가기 쉬운 방향으로 트러스를 배치하여 유연한 힘의 흐름을 유도하는 것이다. 143.6m(폭)${\times}$183.5m(길이)${\times}$21m(높이)의 지붕엔 지붕의 개념인 Flow Truss를 물이 흐르는 방향의 방사형으로 배치하고, 내부에 압축링(Compression Ring Truss)과 외부에 인장링(Tension Ring Truss)를 설치하여 힘의 흐름을 단순화시켰고, 실내에서 보기에 플로우 트러스의 간격을 넓게 유지함으로써 개방감을 극대화시켰다. 또한 Flow Truss는 동일한 곡률과 길이로 설계하여 표준화시킴으로써 시공성과 경제성을 동시에 만족토록 하였다. 현재 저층부 시공은 거의 완료된 상황이고, 곧 지붕을 설치할 예정이다. 본 고에서는 돔 지붕의 형성 개념과 설계 과정을 살펴보고, 접합상세 등의 해결에 대해 살펴보겠다.

Elderly people should have a great load because of life in facility away from their a community. It needs careful concern for Public spaces. The mayor questions of this thesis are to seek a correlation of a Layout patterns of Public-spaces and Resident's behaviors in Public spaces ; and to seek a correlation of a Layout patterns of Public-spaces and the scale of Paid residential care facilities for Elderly people in Korea and Japan. Finally, the thesis suggests the layout patterns of public spaces that is suitable to scale of facilities and Elderly people's behaviors.

핀홀 카메라는 그 특성상 전체 공간 중에서 일부분만을 촬영할 수 있으므로 전체 공간을 염두에 두는 3D 재구성에서는 구면 영상에 비해 많은 데이터를 확보해야 한다. 본 논문에서는 다수의 구면 영상에 촬영된 물체의 실제 3차원 위치를 추정하는 방법을 제안한다. 두 카메라의 배치 간격이 가까운 스테레오 비전과는 달리 제안하는 방법에서는 여러 대의 카메라를 넓은 간격으로 배치하여 장애물에 대한 폐색을 극복하도록 한다. 구면 카메라의 화각은 공간 전체를 담을 수 있기 때문에 촬영 간격과 카메라의 회전각이 크더라도 전 영역에 대한 일치 관계를 계산할 수 있다. 실험 결과 구면 영상에 나타난 물체의 실제 위치에 근접한 결과를 얻을 수 있었다.

본 연구에서는 GIS, GPS, Web기술을 이용하여 레미콘 차량의 운행상황과 이동경로 등을 실시간으로 파악 한 후 차량의 위치와 목적지 도착시간, 복귀예정시간 등을 예측하는 레미콘 차량 관제 시스템을 레미콘 배치플랜트의 도입 시 효율성을 평가하였다. 그 결과 공사현장에서 복귀하는 레미콘 차량의 도착시간이내 복귀거리등을 사전에 미리 차량관제서버로 전송해 주는 알림기능으로 인해 배치플랜트의 다음 배차를 위한 레디믹스가 반자동적으로 작동하여 차량의 대기나 다음 배차를 위한 차량 위치 파악 등의 지연시간이 현저히 감소되었다. 이는 1일 8시간을 기준 20대의 레미콘 차량을 분석 한 결과 실시간 운행정보를 통한 배치플랜트의 가동으로 인해 1일 155분의 시간이 절감되어 일 평균 2.5대의 레미콘 차량의 추가적 운행이 가능하였으며, 이를 비용으로 환산시 일 평균 90만원, 월 약 1920만원의 추가적인 이익이 발생하여 레미콘차량 관제 시스템에 따른 배치플랜트의 작동은 기업차원에서의 경제적 측면을 고려할 때 매우 효율적인 것으로 판단되었다.

Placement is an important step in the physical design of VLSI circuits. It is the problem of placing a set of circuit modules on a chip to optimize the circuit performance. The most popular algorithms for placement include the cluster growth, simulated annealing and integer linear programming. In this paper we propose a genetic algorithm searching solution space for the placement problem, and then compare it with simulated annealing by analyzing the results of each implementation.
