The performance of peripheral devices is improving rapidly to meet the needs of users for multimedia data. Therefore, the peripheral interface with wide bandwidth and high transmission rate becomes necessary to handle large amounts of data in real time for multiple high-performance devices. PCI Express is a fast serial interface with the use of packets that are compatible with previous PCI and PCI-X. In this paper, we design and verify general peripheral interface using serial link. It includes two kinds of traffic class (TC) labels which are mapped to virtual channels (VC). The design adopts TC/VC mapping and the scheme of arbitration by priority. The design uses a packet which can be transmitted through up to four transmission lanes. The design of general peripheral interface is described in Verilog HDL and verified using ModelSim. For FPGA verification, Xilinx ISE and SPARTAN XC3S400 are used.We used Synopsys Design Compiler as a synthesis tool and the used library was MagnaChip 0.35um technology.

The additional mechanism Is required to set up a secure connection among the communication subjects in the internet environment. Each entity should transfer and receive the encrypted and hashed data to guarantee the data integrity. Also, the mutual authentication procedure should be processed using a secure communication protocol. The SSL/TLS is a protocol which creates the secure communication channel among the communication subjects and sends/receives a data. Although the OpenSSL which implements the TLS is using by many developers and its stability and performance are proved, it has a difficulty in using because of its large size. So, this Paper designs and implements the secure communication which the users can use easily by modification works of OpenSSL library API. We proved the real application results using the DRM client/server case which supports a secure communication using the implemented API.

National Union Catalog presupposes an information infrastructure which permits users to identify and locate materials of all the domestic libraries and to share materials among libraries. Recently, there have been developed national union catalog projects in many countries using Z39.50 protocol implementation. In Korea, multi-union catalogs based on the types of libraries, i.e., public, academic, and special libraries, have been constructed separately. The virtual national union catalog which is a decentralized electronically accessible catalog unified by linking the databases of several institutions using Z39.50 is preferable to a union catalog implemented by a single centralized database. In this paper, hybrid union catalog is suggested with mixtures of centralized union catalogs and Z39.50-based distributed search systems for the development of a national union catalog. It is also suggested that the roles of a national library and centers for union catalog, and relationships between two types of institution for making sound ground for implementing the virtual Korean union catalog.

The preservation metadata which is defined the property and history of changes must be describes logically and structurally for implementing long-term digital preservation. The preservation metadata makes the users to access and retrieve authentic digital resources and the managers of digital archives to manage and preserve more effectively the digital resources. his paper is review of recent developments relating to digital preservation metadata including the taxonomy of information object classes of Reference Model of OAIS and outlines some library-based projects. Next, the paper investigates how to develop and use the preservation metadata in university libraries and what is the core preservation metadata elements. Finally, the paper recommends the set of preservation metadata elements with broad applicability to digital preservation in university libraries.

Emerging Web 2.0 services such as Twitter, Blogs, and Wikis alongside the poorlystructured and immeasurable growth of information requires an enhanced information organization approach. Ontology has received much attention over the last 10 years as an emerging approach for enhancing information organization. However, there is little penetration into current systems. The purpose of this study is to propose ontology implementation and methodology. To achieve the goal of this study, limitations of traditional information organization approaches are addressed and emerging information organization approaches are presented. Two ontology data models, RDF/OW and Topic Maps, are compared and then ontology development processes and methodology with topic maps based medical information retrieval system are addressed. The comparison of two data models allows users to choose the right model for ontology development.

This study is to research quintessence of information service in the libraries by interpreting 'Information' as it is ubiquitous. For the purpose, it investigates and analyzes information behaviors of the libraries in information-cultural history. The meaning of 'ubiquitous' is understood as a practice that everything we need should be inherent in our lives for its usefulness and effectiveness. Information is intrinsic in our lives and the libraries, information management systems, have been evolved by extending the intrinsic value of information, 'ubiquity'. Human being's history results from information behaviors and the meaning of the libraries consists of production, accumulation, organization and distribution of the libraries. It should be recognized that the ultimate purpose of the library services is for their users. Consequently information systems and technological networks in the libraries should be focused on applications and inherence for the purpose. Model studies of the libraries should be developed to user-centered information services that substantialize the interpretation of information, as it is ubiquitous. This study is a trial for defining the quintessence of the libraries. Furthermore, it provides foundation of understanding what the libraries are.

This exploratory study describes the social bookmarking perceptions and behaviors of students in university courses. Although an emerging discussion regarding the value of social bookmarking tools exists, how users adopt tools in practice is not well known. Students were asked to utilize the bookmarking tool del.icio.us to store information relating to course projects. They were also asked to comment how they employed del.icio.us for course projects. The study analyzed student perceptions and behaviors when using social bookmarking tools for university coursework. The study noted that the use of tags, notes, and networking within these social bookmarking tools remained less active and social bookmarking services in Web 2.0 as shared collaboration, shared communities, and vertical search were less present. Utilizing social bookmarking tools to facilitate personal information management includes the activities of information use, information re-use, and mobility.

The fundamental issue of information retrieval in the Internet-based society is closely interrelated with the characteristics of language selected. The McCune-Reischauer Romanization system is not only considered as the international standard for romanizing Korean language, it is also familiar to the majority of the Korean material users internationally. McCune-Reischauer system is adopted by the ISO, UNGEGN, ALA, LC, British PCGN, BL, and the relevant agencies in Europe, Canada and Australia etc. Encouraging for switching to the new Romanization system(2000) would result in complications among the library's catalogs and online databases, causing confusion for both staffs and readers. This paper analysed that the international efforts and rules for Romanizing Korean language materials and recommended direction for bibliographical issues.

The purpose of this study is to identify and systematize various facet elements required by users in fiction search situations from book tags to improve the fiction search environment. Based on the Ranganathan's PMEST formula, the basic facet system of the fiction was defined as 1) the personality that forms the fiction material, 2) the content and external characteristics that compose the fiction, 3) the reader interaction with books, 4) spatial information related to fiction and reading activities, and 5) time information related to fiction and reading activities. Out of approximately 310,000 tags assigned to 7,174 fiction, 3,730 core tags were selected and content-analyzed. As a result, various attributes were systematized around the top 25 categories of the fiction facets. The results of this study can be applied to facet navigation of OPAC and fiction DB in the future.
