'The Library and Information Science' originated from the 'Library Science'. A school of academic reputation of the West is calling nm of studies by the name of 'Library, Archives, and Information Science' and studying materials, knowledge and information of the library, archives, and information centers. I think that many of the researcher neglect basic studies of the library and information science. Therefore, I'd like to call attention to the fact.

도서관에 RFID 시스템을 도입함으로써 업무의 효율을 높일 수 있다. R-LIM2는 도서의 위치까지 안내하는 기능을 제공하는 RFID 기반의 진보된 도서관리 시스템이지만 위치 추정과 내비게이션에 다수의 안테나 및 별도의 PDA를 사용함으로써 경제적으로는 비효율적이었다. 이에 본 논문에서는 R-LIM2의 내비게이션 기능을 별도의 기기 없이 사용자가 휴대한 스마트폰으로 가능하게 하고, 기존에 구축되어 있는 무선 네트워크 인프라를 활용하여 위치 추정이 가능하게 함으로써 보다 경제적이고 효과적인 도서위치 검색 시스템을 개발하였다.

This study applied automatic classification using table of contents (TOC) text for 6,253 social science books from a newly arrived list collected by a university library. The k-nearest neighbors (kNN) algorithm was used as a classifier, and the ten divisions on the second level of the DDC's main class 300 given to books by the library were used as classes (labels). The features used in this study were keywords extracted from titles and TOCs of the books. The TOCs were obtained through the OpenAPI from an Internet bookstore. As a result, it was found that the TOC features were good for improving both classification recall and precision. The TOC was shown to reduce the overfitting problem of imbalanced data with its rich features. Law and education have high topic specificity in the field of social sciences, so the only title features can bring good classification performance in these fields.

With the proliferation of E-Commerce, product informations and services are provided to customers diversely. Thus customers want a software agent that can retrieve and recommend goods satisfying various purchase conditions as well as price. In this paper, we present a MAS (multi-agent system) for book information retrieval and recommendation in E-Commerce. User's preference is reflected in the MAS using the profile which is taken by user. The proposed MAS is composed of individual agents that support information retrieval, information recommendation, user interface, and web robots and a coordination agent which performs information sharing and job management between individual agents. Our goal is to design and implement this multi-agent system on a Windows NT server. Owing to the workflow management of the coordination agent, we can remove redundant information retrievals of web robots. From the results, we could provide customers various purchase conditions for several online bookstores in real-time.

This study analyzed the contents of Goodreads review data, which is a social cataloging service with the participation of book users around the world, to identify the preference factors that affect book users' book recommendations in the library information service environment. To understand user preferences from a more detailed point of view, sub-datasets for each rating group, each book, and each user were constructed in the sample selection process. Stratified sampling was also performed based on the result of topic modeling of review text data to include various topics. As a result, a total of 90 preference factors belonging to 7 categories('Content', 'Character', 'Writing', 'Reading', 'Author', 'Story', 'Form') were identified. Also, the general preference factors revealed according to the ratings, as well as the patterns of preference factors revealed in books and users with clear likes and dislikes were identified. The results of this study are expected to contribute to more sophisticated recommendations in future recommendation systems by identifying specific aspects of user preference factors.

본 논문에서는 유비쿼터스 환경에 발맞춰 도서관에 적용되고 있는 RFID 시스템에 대한 기술적 개요와 유용성에 대해 고찰하고, 국내 외 도서관 현황과 현 RFID 시스템의 비교분석 및 사례조사를 통해 기존 RFID 도서관리 시스템의 문제점을 도출하였다. UHF 대역 RFID를 통하여 기존 문제점의 해결 방안을 제시하였으며, 구체적인 시스템 설계를 통해 업무의 효율성 및 이용자 편의성을 RFID 및 USN 기술을 통하여 향상시키는 방을 제시하였다. 본 논문은 정보이용자에 대한 서비스 및 관리 측면에서 효율성을 극대화하여 도서관 선진화를 추구하고자 하였다.

For sustainable use of the resources of uninhabited islands of Korea, their ecological economic potential needs to be fully integrated into their management policy and the carrying capacity of the islands should be evaluated before using or developing them. The emergy methodology was used to evaluate the ecological economic value and carrying capacity of Sungap-do which is an uninhabited island in Incheon, Korea. The system boundary for the emergy evaluation of the island included the sea area within 1km from the high tide level, following the management boundary for the uninhabited islands of Korea stipulated in the Law on the Conservation and Management of Uninhabited Islands. The total renewable emergy input to Sungap-do was $1.04{\times}10^{20}$ sej/yr from tidal energy. The annual ecological economic contribution of the island was evaluated high at 29.9 billion Em￦/yr. If Sungap-do were developed to the national average, its carrying capacity was 6,586 persons at the current living standard of Korea. The carrying capacity of Sungap-do for the long-term sustainability scenario was 2,337 persons at the same living standard as in the developed scenario. When only emergy contribution of the land area was considered, the carrying capacity of Sungap-do sharply decreased to 14 persons for the developed scenario and 5 persons for the long-term sustainability scenario. The carrying capacity of the uninhabited islands of Korea including Sungap-do, thus, needs to be considered from the initial stage of utilization or development projects to sustain the ecosystem benefits and their sustainable uses.

The purpose of this study is to analyze the effects of the bestseller ranks on the book circulations in public libraries. To achieve this goal, the weekly data sets of 179 books' library circulation and bestseller list from January 1, 2018 to December 29, 2019 were constructed based on the data collected from BigData MarketC and YES24. Three methods for analyzing panel data including linear regression, fixed-effect, and random effect models were compared, and it turned out that fixed-effect model was better than other methods. The results show that the average ranks of bestsellers were associated with their public library circulations visually. Also, the analysis of fixed-effect model showed that the single rank decline of a book on the bestseller list decreases its average circulation of 0.108 while the size of effect varied depending on subject of books. The study empirically demonstrated the impact of a bestseller list on people's book circulation behavior, suggesting that public libraries need to reference sociocultural context as well as bestseller book lists to predict library user needs and to formulate collection development policy.

The purpose of this study is to diagnose the current status of alternative materials in Korea and to suggest directions and goals for the development of alternative materials. The comprehensive list of national alternative materials and the list of popular and new books were analyzed using the collection evaluation method. Results first the percentage of alternative material collections based on the popular book list for 10 years is 90.1%. The production rate of alternative materials is low in the subjects of 'Language', 'Art' and 'Technology and Science'. Most of the service formats were 'text only daisy'. Second, the CCHR(Common Collection Holding Ratio) and CUI(Collection Uniqueness index) of alternative materials were analyzed using the union catalog. Libraries with a large volume of books have a high proportion of CCHR and CUI. Topics with the highest CCHR are 'Literature' and 'Social Science'. The subjects with the highest collection uniqueness index are 'religion', 'art', and 'language'. Third, the replacement ratio of new books for 3 years is 5.09%. During the same period, the average book purchase rate of public libraries was 8.83%. The average book purchase rate in public libraries is 8.83%, and it is necessary to increase the collection rate of alternative materials based on this ratio.
