Open-source software developments are basically Internet-based communities that voluntarily collaborate in developing software on the Internet and such Internet communities have become an important cultural and economic phenomenon. As a result, the emergence of open-source software has presented a challenge to the traditional offerings by providing free alternatives. The objective of this article is to review the possibility of the adoption of open source software in the creation of digital libraries, highlights advantages and disadvantage preservations. Among our objective also explaining the request of such software at the present time and the criteria evaluated in the digital preservation through surveying the best open source software from the reality of intellectual production, and standards that are being built to evaluate and choose what software to create a digital library without other software available. To achieve the above objectives, we shed the light on the top 11 open-source software to manage Libraries in addition to standards that may represent the basic building block for the selection of the appropriate systems to the needs of the digital library. This article relied on the descriptive approach by reviewing a series of studies and scientific research works related to the subject of the current study. Accordingly, the most prominent of the findings of this work is its illustration of the close association between open source software and the library community, both of which represent free culture. Also it is shown that the selection process of open source software has some obstacles most notably as there are no clear and reliable criteria for selecting these systems. Current study has concluded a set of recommendations, notably awareness of the role and importance of open source software and the facilities it provides in managing digital content.

This paper provides an overview of the emergence of resource discovery systems and services, along with their advantages, best practices, and current landscapes. It outlines some of the key services and functionalities of a comprehensive discovery model suitable for academic libraries in developing countries. The proposed model (VuFind as a discovery tool) performs like other existing web-scale resource discovery systems, both commercial and open-source, and is capable of providing information resources from different sources in a single-window search interface. The objective of the paper is to provide seamless access to globally distributed subscribed as well as open access resources through its discovery interface, based on a unified index. This model uses Koha, DSpace, and Greenstone as back-ends and VuFind as a discovery layer in the front-end and has also integrated many enhanced search features like Bento-box search, Geodetic search, and full-text search (using Apache Tika). The goal of this paper is to provide the academic community with a one-stop shop for better utilising and integrating heterogeneous bibliographic data sources with VuFind (https://vufind.org/vufind).

디지털도서관을 단순한 정보유통 구조의 한 부분으로 정의하지 않고 디지털도서관 그 자체를 자원의 생산, 유통 그리고 재생산을 위한 무형의 가치창출 행위로 인식하였으며 디지털자원의 속성을 해석함으로써 디지털도서관을 설계하였다. 즉, DRM(Digital Resources Management)의 가치를 디지털도서관으로 보았으며 그것을 전통적 도서관의 진화로 인식하였다. 이미 대학도서관들의 오픈액세스 자원생산이 이루어지고 있으며 클라우드 컴퓨팅 환경에서의 도서관 디지털장서 관리와 공유가 가능함을 보여줌으로써 출판이 가미된 디지털도서관의 가능성을 보여주었다.

The role of the interconnect network, which connects computing nodes to each other, is important in high-performance computing (HPC) systems. In recent years, the peripheral component interconnect express (PCIe) has become a promising interface as an interconnection network for high-performance and cost-effective HPC systems having the features of non-transparent bridge (NTB) technologies. OpenSHMEM is a programming model for distributed shared memory that supports a partitioned global address space (PGAS). Currently, little work has been done to develop the OpenSHMEM library for PCIe-interconnected HPC systems. This paper introduces a prototype implementation of the OpenSHMEM library through a switchless interconnect network using PCIe NTB to provide a PGAS programming model. In particular, multi-interrupt, multi-thread-based data transfer over the OpenSHMEM shared memory model is applied at the implementation level to reduce the latency and increase the throughput of the switchless ring network system. The implemented OpenSHMEM programming model over the PCIe NTB switchless interconnection network provides a feasible, cost-effective HPC system with a PGAS programming model.

This study was conducted under the premise that the university library's subject specialization room is in need of major modifications in order to accommodate the needs of various majors. The subject specialization room will be able to support university library users who are inclined to use the general reading room. Therefore, the study presents spatial planning for the average university library's subject specialization room by taking into account student majors. This could be a guideline for the construction and renovation of university libraries in the future. The summary of results for this study and the conclusions are as follows: 1)Natural sciences subject specialization room should be, partially connected with the humanities/social science subject specialization room in order to provide an open-concept reference room. In the shared area connecting the two subject specialization rooms needs to be installed a staff counter and subject specialist librarian service booth for users of both subject specialization rooms. 2)For humanities/social sciences subject specialization room, partially connect with the natural sciences subject specialization room. In the connecting area between the two rooms, plan an open-concept lounge for resting and reading. 3)It is best to plan subject specialization room for art/music/physical education majors separate from the subject specification room of other majors. Structurally separate art/music/physical education major subject specialization rooms from the building or plan a separate room in an art/music/physical education building. Users of art/music/physical education majors showed a high preference for a spatially separated and specialized library structure, which proves that an art/music/physical education library need to be planed based on the specialized library structure found in law school libraries or medical school libraries. Plan the center of the room with open-concept based reading room. Use wall-sides, partitions, or shelves to create reading space separate from the shelving area.

This study is to analyze correlations between 14 factors related to university libraries and the number of professional staff, nonprofessional staff, and total library staff. The results of this study are summarized as follows: 1. In the case of 1992, there are high positive correlations between the number of library staff and 10 of 14 variables : the number of undergraduate enrollments, graduate enrollments, departments, faculty members, school employees and volumes in library, size of library building, total university expenditure and library materials expenditure (coefficient: 0.70-0.99). However, there are little significant correlations between the number of library staff and 2 variables : library open hours and university expenditure per student. Among the above factors, the correlations of the total university expenditure and the library expenditure show a significant difference more than ones of the other factors. 2. In the case of the analysis by 3 years interval in 1984-1992, there are high positive correlations between the number of total library employees and 7 of the above 9 variables, excepted to library open hours and 4 factors related to expenditure (coefficient : 0.73-0.93 in 1984;0.77-0.88 in 1988;0.70-0-92 in 1992). But there are little significant differences among the correlation coefficients by each year. 3. In the results of the correlation analysis between the professional staff and the nonprofessional staff, the number of graduate enrollments, departments, volumes in library and school employees, library expenditure and total university expenditure show higher positive correlation to the professional staff than the nonprofessional staff. However, the number of undergraduate enrollments, faculty members, volumes added in library and volumes loaned, size of library building and library materials expenditure show little significant differences in the correlation coefficients between the professional staff and the nonprofessionalstaff.
