Today's public libraries in communities are on the processes of changes to integrate information and communication technology into traditional library system in order to support current users' demands for the new digital era. The purpose of this study is to examine the changing characters on space design and space uses of community based public libraries by conducting case studies of three branch libraries which were built after 2004 in Ann Arbor, Michigan in the United States. As the conclusion of this research, the findings of the case studies are utilized as basic data for planning and design guidelines for public libraries as community resources. The study summarizes the characteristics of space design and space uses in public libraries as follow; first, the floor plans of small-scale public libraries are open visually as well as spatially. The space organization of the libraries is arranged by potential noise levels, as placing noisy spaces near the entrance halls and quiet spaces at the back. Main book shelves are located in the middle of the library buildings, while seats are arranged along the window sides. By placing various kinds of furniture in open reading areas, library users can select different types of seats and tables for their comforts. Second. the survey of observation also finds that a large number of users often use library computers and personal computers to connect the internet at the libraries. These personal computer users who are new user group in community based libraries preferred to sit in casual study areas and individual tables with one or two seats only. Third, the libraries, in addition, develop and provide various programs and events for people in communities. Especially, the programs for children, the elderly and new comers from the abroad are well prepared, thus provide opportunities for them to visit the libraries in regular bases. The survey finds that family entertainment and leisure activities are the important parts of the program as well as renting music CD and movie DVD are also important reasons for people to come. Thus, the libraries prepare high quality children's space and CD shelves near the entrance hall.

This study is about the pattern of spatial structures of major university campuses in Korea. The pattern is composed of buildings, circulation, and open space within the campus. It is physical structural system which makes campus more educational environment as well as new academic landscape. The pattern is checked on the basis of existing sub-patterns of eleven universities with base data by using computer program, Autocad and Landcadd. The result is that most of campus spatial structures consists of simple and unified grid pattern. Basic educational facilities are at the center of the whole structure as well. Some universities are located in suburb and have large site which makes it more open space oriented pattern, more various exterior space and more specific circulation system. So the campus patterns of recently built is more diverse and has more design components. In most cases, campus does not have strong spatial coherence among its buildings, circulation, and open space. It is important to develop Korean formal campus spatial structure which is intrinsic to its site and is proper to its academic plan. Campus spatial structure should be formulated to embrace diverse demands of university and to accumulate unique university landscape.

PCI Express는 고속, 저전력 등의 특성으로 인하여 프로세서와 주변 I/O 장치들을 연결하는 업계 표준의 버스 기술이다. PCI Express는 최근 고성능 컴퓨터나 클러스터/클라우드 컴퓨팅 등의 분야에서 시스템 인터커넥션 네트워크로서 그 활용가능성을 검증하고 있는 추세이다. PCI Express가 시스템 인터커넥션 네트워크로서 활용가능하게 된 계기는 PCI Express에 NTB(non-transparent bridge) 기술이 도입되면서부터이다. NTB 기술은 물리적으로 두 PCI Express subsystem을 연결가능하도록 하지만, 필요할 경우 논리적인 격리(isolation)를 제공하는 특징이 있다. 또한, PGAS(partitioned global address space)와 같은 공유 주소 공간(shared address space) 프로그래밍 모델은 최근 멀티코어 프로세서의 보편화로 인하여 병렬컴퓨팅 프레임워크로 각광받고 있다. 따라서, 본 논문에서는 차세대 병렬컴퓨팅 플랫폼을 위하여 PCI Express 환경에서 OpenSHMEM을 구현하기 위한 초기 OpenSHMEM API를 설계 및 구현하였다. 본 연구에서 구현한 15가지 OpenSHMEM API의 정확성을 검증하기 위해서 Github의 openshmem-example 벤치마크의 수행을 통하여 확인하였다. 현재 시중에서는 PCI Express 기반 인터커넥션 네트워크는 가격이 매우 비싸고 아직 일반인이 사용하기 용이하도록 NIC형태로 널리 보급되지 않은 실정이다. 이러한 기술개발 초기단계에서 본 연구는 PCI Express 기반 interconnection network를 RDK(evaluation board) 수준에서 실제로 동작하는 실험환경을 구축하고, 여기에 추가로 최근 각광받는 OpenSHMEM software stack를 자체적으로 구현하였다는 데 의의가 있다.

POPS(Privately Owned Public Spaces) is one of the major component that vitalize the city by private sectors providing open-spaces to the public. It holds great significances and possibilities within CBD(Central Business District) which lack open-space and green-space. Despite of its importance, a large number of problems such as deficient accessibility for the public and being unpractical from constructing only with formality occur in existing POPS. POPS should be for both owners and public because it is a public space located within a private estate. To vitalize POPS, functions like "diversity", "accessibility and connectivity", and "usability" are essential. Providing diverse types of spaces makes dynamic city, and the spaces must have easy access by public and variety of functions. Managements by diverse types of POPS are necessary to improve availability and to provides suitable spaces. To make diverse types of POPS, advanced classifications of type and clear criteria are required. From aspect of accessibility and connectivity, firstly detailed instructions for the arrangement are necessary for reinforcement. Specific research on means of connection such as how many faces of POPS should adjoin streets and in which direction it should be facing should be applied. Purposes of POPS must be specified depending on the type of POPS. By connecting adjacent buildings with POPS, one of the main principal of vitalizing POPS, inflow of people can be increased. Accordingly, improvements of design guidelines in "diversity", "accessibility and connectivity", and "usability" can be suggested to vitalize POPS. With these concerns in mind, this paper analyzes problems of current Seoul POPS guidelines with three aspects.

The effect of soil foundation plays active role in optimum design of steel space frames when included. However, its influence on design can be calculated after a long iterative procedure. So it requires longer computer time and more computational effort if it is done properly. The main purpose of this study is to investigate how these effects can be calculated in more practical way in a shorter time. The effects of semi-rigid column bases are taken into account in optimum design of steel space frames. This study is carried out by using JAYA algorithm which is a novel and practical method based on a single revision equation. The displacement, stress and geometric size constraints are considered in the optimum design. A computer program is coded in MATLAB to achieve corporation with SAP2000-OAPI (Open Application Programming Interface) for optimum solutions. Four different steel space frames including soil structure interaction taken from literature are investigated according to different semi-rigidly supported models depending on different rotational stiffness values. And the results obtained from analyses are compared with the results available in reference studies. The results of the study show that semi-rigidly supported systems in the range of appropriate rotational stiffness values offer practical solutions in a very short time. And close agreement is obtained with the studies on optimum design of steel space frames including soil effect underneath.
