This paper examines the development process of China's venture capital industry and the characteristics of its capital spatial configuration. The results reveal that the development of China's venture capital industry has its unique modality, which varies greatly from existing studies, namely, the desynchronized paces of industry development as well as the regional real capital supply and demand trend. More detailed observation shows the Chinese venture capital's spatial configuration has three main characteristics: first, the separation of the registered location and the actual location of business operation; second, the division and spatial configuration of the venture fund's capital circulation. To find the relevant factors related to the above phenomena, a correlation analysis was conducted between both market factors and non-market factors with the above capital spatial configuration. The analysis confirmed that besides the market factors, local legislative condition also presents a high correlation with the phenomena.

For the construction of a large underground space with a complex plant installed, it is necessary to analyze the stability considering the ground conditions and various load conditions. In this paper, finite element analysis was performed to analyze the support load that can be used in the design of a large underground space for high-density arrangement of complex plant. An analysis of underground continuous wall (D-wall) was performed considering the load and horizontal earth pressure in the large underground space. In addition, foundation ground analysis was carried out according to the load condition of the complex plant. In order to shorten the construction period, increase the space layout utilization, and secure the stability of the plant structure when installing the complex plant underground, the pipe rack module structure analysis was conducted. This study proposes a design and construction method for the optimal arrangement of underground complex plants using the analysis results.

아름다운 자연경관은 인구의 도시집중과 토목 건축 기술 기반의 도시공간구조 다양화로 자연경관은 그 모습을 잃어가고 있다. 이러한 변화 이변에는 자연경관의 보존에 대한 도시민의 욕구가 날로 증가하고 있어 경관자원의 보전 및 보호를 위한 체계가 필요한 실정이다. 체계적이고 종합적인 경관관리로 도시민들에게 우수한 경관을 제공하기 위해서는 경관의 변화 정도를 정량적이고 객관적으로 측정하고 모니터링 할 수 있어야 한다. 따라서 본 연구에서는 건물배치 및 높이에 따른 산림녹시율을 3D GIS기반에서 분석하여 산림녹시율이 인간에게 미치는 영향을 규명하고자 한다.

분산 파일 시스템에서 파일을 복제하는 목적의 하나는 파일의 가용성을 높이는 것이다 서버들로 이루어진 시스템에서 가용도 문제는 주로 오류 상황이 대상이다 반면에 데스크탑으로 구성된 경우 각각이 상대적으로 가용도가 낮고 그 편차도 커서 파일의 가용도를 최적화 하도록 복제본을 저장하는 것이 기본적인 문제가 된다. 파일 단위 복제 기법에서는 파일 수가 참여 시스템 수에 따라 기하급수적으로 증가하고 파일 배치 때마다 가용도 최적화를 수행해야 하는 문제가 있다. 본 논문에서는 저장 공간 단위 복제 기법을 제안한다. 데스크탑 시스템의 저 장롱간을 고정 크기의 페이지들로 나누고 이들을 조합해서 일정한 가용도를 가지는 페이지 그룹을 형성한다. 파일들은 이 페이지 그룹에 저장된다. 페이지의 개수가 파일 수가 아닌 시스템 수에 의존하고, 파일 배치 시점과 무관하게 페이지 그룹을 만들 수 있는 장점이 있다. 최종 가용도를 높이고 연산 시간을 줄이기 위해 ILS(Iterated Local Search )방법을 이용만 탐색을 수행한다.

It is very important for libraries to provide their patrons with spaces that are used comfortably. In this paper, first we propose some improvement plans for space organizations of Gwacheon Public Library based on its patrons' behavioral research. It has a big meaning from the view of library marketing, which aims at improving patrons' satisfaction. Then we investigate how study tables are used based on the data taken at Kyushu University Library in Japan. Finally we put some proposals on libraries' space organization based on these investigations.

According to increasing of various location-based services, distributed data stream processing techniques have been widely studied to provide high scalability and availability. In previous researches, in order to balance the load of distributed nodes, the geographic characteristics of spatial data stream are not considered. For this reason, distributed operations for adjacent spatial regions increases the overall system load. We propose a operation allocation scheme considering the characteristics of spatial operations to effectively processing spatial data stream in distributed computing environments. The proposed method presents the efficient share maximizing approach that preferentially distributes spatial operations sharing the common query regions to the same node in order to separate the adjacent spatial operations on overlapped regions.

This study is a case study to identify the spatial composition and structural problems of existing schools for spatial innovation as a future school that can operate a credit system for old high schools and establish a mid-to-long-term arrangement plan as a credit system operating school capable of various teaching and learning in the future. The study results are as follows: First, most of the problems of the old high schools entailed that there was very poor connectivity between buildings as most of them were arranged in a single, standard design-type unit building and distributed in multiple buildings. In addition, the floor plan of each building is suggested to be a structure in which student exchange and rest functions cannot be achieved during the break period due to the spatial composition of the classroom and hallway concepts. Second, in the direction of the high school space configuration for future school space innovation, the arrangement plan should be established by reflecting the collective arrangement in consideration of the shortening of the movement route and the expansion of subject areas due to the movement of students on the premise of the subject classroom system. Moreover, it is desirable to provide a square-type space for rest and exchange in the central area where communication and exchange are possible according to the moving class. Third, as the evaluation criteria for relocating old high schools, a space program is prepared based on the number of classes in the future, and legal analysis of school land use and land use efficiency analysis considering regional characteristics are conducted. Based on such analysis data, mid-to-long-term land use plans and space arrangement plans for the entire school space such as the school facility complex are established.

Space Layout has been an issue in the facet of reducing the co2 in that the transportation sector has been to represent almost more than 20% of the total energy consumption for decades. Beside the development of the more efficient transportation systems, an efficient space layout makes it possible to reduce the amount of energy consumption in the transportation sector through allocating the sub-spaces in such an arrangement of minimizing the travel distances. In line with this thinking, this research aims at implementing a simulator which can calculate the vehicle-based travel distance upon a certain space layout. Based on the findings that the vehicle-based travels take place between the two functionally related sub-spaces, this research addresses a method of calculating the vehicle-based travel distance by multiplying the traffic volume of each sub-spaces by the travel distance to the other connected sub-spaces.

주문형 비디오 시스템에서 저장되는 영화들의 다중 액세스를 지원하기 위해 영화들은 비디오 서버의 다수의 디스크에 걸쳐 스트라이프되고, 비디오 서버의 디스크 배열들간의 부하 불균형을 피할 뿐만 아니라 저장 공간과 장치 대역폭을 최대로 이용하기 위하여 영화의 블록들은 디스크 배열에 신중히 배치되어야 한다. 본 논문에서는 영화의 인기도를 고려한 동적 디스크 스트라이핑에 기초하는 그룹교대 라운드로빈이라는 영화 배치 방법을 제안하고, 그것의 성능을 시뮬레이션을 통하여 평가한다.
