The purpose of this study is to provide an actual basic data and helps for arranging the next generation OPAC's interface and function through improving the existing OPAC's interface and improvement in the domestic library. In this study, factors to be importantly considered for improving the OPAC's interface and function were examined based on the preceding studies on OPAC concept & development process, user's library use style, user use style of OPAC, and recognition on library's crisis, and actual condition investigation result. Also, the case analysis on the existing OPAC's interface and function was focused on the search window, search item, search method, alignment function, search result display and search result feedback. Also, the search interface and search function of the next generation OPAC which is provided by the recently-developed domestic and foreign library utilization, and the detailed case were analyzed in the aspect of Library 2.0 service. Finally, the measures for improving the existing OPAC's interface and function in domestic library were suggested.

추천 시스템은 다양한 분야에 적용되는 기술로서 활발한 연구가 진행되고 있고 기존 추천 시스템의 성능을 높이기 위해서 더욱 개인화된 차세대 추천 시스템의 필요성이 대두되고 있다. 본 논문은 하이퍼 개인화 범주에 속하는 사후 필터링기법을 사용한 실시간 상황 인식 추천 시스템을 제안한다. 실시간 상황 인식 추천 시스템은 사용자 행동과 계속적인 동기화로 현재 상황에 가장 적합한 추천 목록을 생성하기 때문에 사용자 기반 협업 필터링 (User Based Collaborative Filtering), 콘텐츠 기반 필터링(Content-based Filtering), 특이값 분해(Singular Value Decomposition)보다 훨씬 미래 지향적인 추천 시스템이다.

IoT (Internet of Things)가 차세대 기술로 각광을 받으면서 않은 IT 전문인들이 대표주자인 웨어러블 디바이스(wearable device) 의 활용도에 많은 관심을 기울이고 있다. 하지만 현재까지 헬스케어(healthcare)와 피트니스(fitness) 서비스 중심으로 구성되는 등 다양성을 갖지 못하고 있다. 본 논문에서는 스마트 위치를 이용하여 장보기에 다양한 편리성을 제공하는 라이프스타일 관련 웨어러블 어플리케이션을 제안한다. 바코드 스캐닝 기능을 통하여 구매한 제품에 대한 정보를 자동으로 검출하여 가계부를 작성한다. 또한 고객에게 현재까지의 구매 내역에 기반하여 최적의 추천상품 목록을 구성하는 서비스도 제공한다.

Because of the creation and transfer of born-digital records, file unit-based record description practices have changed fundamentally. In this study, we analyzed the archival description practices of The National Archives (TNA) to maintain intellectual control in the digital records management environment and to support the access to records of users. TNA has created an archival description based on ISAD(G) but, for describing born-digital records, it changed the guideline for descriptive cataloging practices. As the method of ISAD(G) cannot adhere to born-digital records, the next-generation descriptive standard, Records in Contexts (RiC), is still being developed by ICA. In addition to international efforts, we need to build an archival description system that fits our environment, especially because since the year 2000, TNA's online cataloging system has changed and ISAD(G) has been modified in this process. This study also proposed continuous monitoring of digital archival descriptions, provides an integrated approach to analog records and digital content and strengthens experimentation and cooperation toward an uncertain digital future.

The purpose of this study is to examine and propose to improve the features of a simple keyword search box and faceted navigations of KOLIS-NET operated by the National Library of Korea. A record group of '2011-2020 (776)' under 'Publication date' facet, out of 3,702 records retrieved from a search of '김훈', were examined. Major findings are as follows: (1) Five facets including 'Format', 'Publication date', 'Subject', 'Language' and 'Country' are used to limit search results only in the first step, and multiple facets cannot be simultaneously used; (2) With 'Publication date' facet formed in the span of ten years, a separate publication year cannot be identified; (3) 'Subject' facet based on KDC limits the results only in broad subject classes without sub-facets; (4) Under 'Format' facet, a special format such as large print texts cannot be identified; (5) Without 'Author' facet, authors cannot be identified; and (6) 'Publication date missing', 'Language missing', and 'Miscellaneous subject' record groups cannot be clicked and displayed, a navigation to-and-fro between a brief list and bibliographic records is not smooth, etc. Therefore an application of multiple facets in all stages of limiting the search result, a construction of sub-facets for 'Publication date' and 'Subject' facets, an accurate description and coding of 'General Material Designation', etc. are suggested to improve KOLIS-NET's faceted navigation.

In the 21st knowledge society, libraries should consider OPAC redesign and functional performance improvement by using new web related technology. This paper studied and analyzed case studies of Web 2.0. Library 2.0, domestic and international web portals and libraries. Based on the research, this study implemented Open API and RSS reader and proposes its utilization plan as a next generation OPAC 2.0 service model which can improve OPAC search results and search service.

Discovery service has as its object to cope with the user to take advantage of the collection of the library as possible to index and search, one step further, the interface by more efficiently to the user's information needs. Discovery service has features such as providing a ranking and navigation services to subdivide the search results by facet results along the suitability and visually rich display, suggestions, recommendations associated resources. In this study introduces the status of discovery services such as discovery service products, usage status, and features, and compares and analyzes the use agencies, content status, main functions, and features of the three discovery services used in Korea library.

Emulab software was developed by the team of University of Utah and it has been replicated at dozens of other sites in the world. Although KREONET Emulab, which established by the Korea Institute of Science and Technology Information, has only a modest number of compute nodes it has been provided an ideal playground to conduct various research for network protocols, cyber security and convergence research. A testbed is a critical enabler of experimental research and researchers only carry out the experiments that are supported by the testbed. This paper outlines the Utah Emulab's status and use types among the last 10 years of operation results and compares them with the ones with the KREONET Emulab. In addition, Testbed-as-a-Service(TaaS) is discussed to upgrade the testbed for the convergence research community services.
