Name Authority Control is useful not only to manage author information but also to gather other names of authors in order to provide access points in libraries and other institutes. The purpose of this study is to find problems through comparing and analyzing Literature Translation Institute of Korea Author Database, Korean name authority records of national libraries in the U. S., Japan and Korea. The results of the study are as follows. First, Literature Translation Institute of Korea Author Database missed some useful information about Korean writers in translated books in other countries. Second, the name authority file of Library of Congress and National Diet Library did not include the variant names, dates of authors' birth and death date, and filled out incorrect variant names with some birth and death dates. Third, English and Chinese character variants of Korean authors were not found in the National Library of Korea. To solve these problems, revisions of Korean author database, open access to National Library of Korea name authority file, and a strong participation of VIAF were suggested.

Are the benefits derived from ICT based reference and information service worth the financial and other commitments devoted to it? In an attempt to answer this, this study delved into finding out the perceived benefits; the rational for ICT based reference services in Nigerian university libraries. The main objectives were to find out the purposes for using ICT facilities in reference services delivery and the perceived benefits derived from using ICT resources in reference and information services. Being a survey, questionnaire was used to collect data from the librarians of twelve (12) universities; two (2) each sampled from the six geopolitical zones of Nigeria. Data was analyzed using frequencies, mean scores and standard deviations. ANOVA statistical analysis was used to test the hypothesis of no significance difference in the benefits derived from ICT based reference services using p-value of 0.05 to calculate the level of significance. Findings showed that librarians and library users made use of ICT facilities for different reference purposes especially to obtain information they need using the internet. Other reference needs for which patrons used the ICT facilities included: - access to current e-books and e - journals, user education and access to global information in other libraries. Provision of current awareness services (CAS) and selective dissemination of information services (SDI), on-line searching using workstations in the library, provision of on-line public access catalogue (OPAC) services, keeping statistics of users of the reference section and compilation of bibliographies. Further findings showed that the librarians and library users derive a lot of benefits from their use of ICT facilities in reference services. The results showed that easy retrieval and dissemination of information to patrons were ranked highest by the librarians amongst others.

Network virtualization is an emerging technology for solving the rigidity of the physical network infrastructure. The innovative technique virtualizes all resources in the network, including the network links and nodes, and provides a number of virtual networks on a single network infrastructure. In order to realize a virtual network, a thorough and complete monitoring of all resources in the network should be performed firstly. OpenFlow is an open source stack for network virtualization. However, it is impossible to apply OpenFlow to AP-based legacy wireless LAN environment because OpenFlow targets ethernet-based LAN environment. In this paper, we implement an adaptor-styled virtual switch for AP-based wireless LAN through customizing the Open vSwitch which is a virtual switch of OpenFlow. The evaluation test results show that the implemented OpenFlow stack operates successfully. The implemented OpenFlow stack can now be plugged immediately in existing AP-based wireless LAN environment and plays network resource monitoring. In the future, we can develop wireless LAN virtualization applications on the wireless OpenFlow stack.

Researchers' performances have been evaluated by contributing to the academic journals officially, and academic journals expanded both quantitatively and qualitatively since academic societies, publishers, and universities has concentrated on publishing journals. Recently, access and usage of academic information was restricted due to commercialization strategies and sudden rising of prices, and against this situation, OA movement came out arguing that academic information should be open to everyone freely. This article studies the case of KOASAS which is based on DSpace, one of the typical institutional repositories, and intends to show up the necessity to construct repositories in institutions universities and suggest the method to make full use of repositories.

Legal deposit system is an essential tool for a national library to ensure the preservation and access to a nation's intellectual heritage over time. Substantial amounts of digital materials of national cultural value are already being published. There is a global trend towards extending legal deposit to cover digital materials in order to maintain comprehensive national archives. This paper gives a progress report of some countries around the world whose legal deposit laws have already updated or are under revision. Some strategies are suggested for the digital collection building of the Korean National Digital Library which will open in 2008.

Web applications typically interact with databases. Therefore, it is very crucial to understand which web components access which database resources when maintaining web apps. Existing research identifies interactions between Java web components, such as JavaServer Pages and servlets but does not extract dependencies between the web components and database resources, such as tables and attributes. This paper proposes a dynamic analysis of Java web apps, which extracts such dependencies from a Java web app and represents them as a graph. The key responsibility of our analysis method is to identify when web components access database resources. To fulfill this responsibility, our method dynamically observes the database-related objects provided in the Java standard library using the proxy pattern, which can be applied to control access to a desired object. This study also experiments with open source web apps to verify the feasibility of the proposed method.
