Abstract

The objective of this study was not only to evaluate different academic library homepages but to hit upon and suggest a reformation plan for their future improvement. For this purpose. academic library web pages of Korea were divided into three major groups -- those of national universities, private ones, and junior colleges. Their web pages were evaluated using a number of criteria. Also, their circumstances and problems were tried to grasp and the methods to be corrected were suggested in this thesis. Literature review were performed for this study and suggestions and advices from professional groups that is called Delphi method were used as a tool to achieve the objective of this study. For a basic analysis, frequency analysis and descriptive statistics were used for analysing data. Also, t-test, ANOVA, and chi-square analysis were used to examine whether there are any significant differences in each groups or not. and Pearson product-moment correlation coefficients were used to find out the correlation among several variables.

Abstract

In many information retrieval experiments, the data fusion techniques have been used to achieve higher effectiveness in comparison to the single evidence-based retrieval. However, there had not been many image retrieval studies using the data fusion techniques especially in combining retrieval results based on multiple retrieval methods. In this paper, we describe how the image retrieval effectiveness can be improved by combining two sets of the retrieval results using the Sobel operator-based edge detection and the Self Organizing Map(SOM) algorithms. We used the clip art images from a commercial collection to develop a test data set. The main advantage of using this type of the data set was the clear cut relevance judgment, which did not require any human interven- tion.

Abstract

In this study, the author examined medical information management research trends in abroad and Korea from the perspectives of library and information science. LISA was used to collect research data in abroad from 2007 to 2010 (a total of 225 research articles). Korean studies were investigated using DBPIA to compare research trends. Content analysis results based on subject category show that research in abroad increased consistently and electronic resources and collection-related subjects were frequently studied. In Korea, the electronic resources and collection-related research proportion was also high, and much research was done in the areas of bibliometrics. However, medical information management researches did not increase in Korea between 2000 and 2010.

본 연구는 대학 도서관 사용 증진을 위하여 개인별 맞춤 도서 추천시스템을 구축하는 것을 목적으로 한다. 특히 사용자의 아이템에 대한 선호도가 존재하는 다수의 추천시스템과는 달리, 선호도가 존재하지 않을 때에 도서 추천이 가능하도록 하는 방안인 도서관 이용자의 도서 대출 목록과 성향을 활용하여 평가지표를 생성하는 방법을 제안하고자 한다. 이용자가 아직 읽지 않은 책에 대한 예상 선호도를 산출하는 방식으로 도서를 추천하는 행렬 분해 방법인 Singular Value Decomposition(SVD)과 Stochastic Gradient Descent(SGD) 알고리즘을 활용한 모델을 구축했다. 더불어 유사도가 높은 이용자 그룹 내의 도서 대출 목록을 참조하여 추천하는 사용자 기반 협업 필터링 알고리즘을 활용해 모델을 구현했다. 최종적으로 평가지표를 활용한 세 가지 모델에 대하여 사용자 평가를 진행했다. 각각의 모델이 제시한 개인별 맞춤 도서 다섯 권의 목록을 해당 대출자에게 제공하고, 추천 도서에 대한 만족/불만족 여부를 이진화 점수화하여 모델에 대한 평가를 진행했다.

Abstract

The purpose of this study is to propose a personalized book recommendation system to promote the use of university libraries. In particular, unlike many recommended services that are based on existing users’ preferences, this study proposes a method that derive evaluation metrics using individual users’ book rental history and tendencies, which can be an effective alternative when users’ preferences are not available. This study suggests models using two matrix decomposition methods: Singular Value Decomposition(SVD) and Stochastic Gradient Descent(SGD) that recommend books to users in a way that yields an expected preference score for books that have not yet been read by them. In addition, the model was implemented using a user-based collaborative filtering algorithm by referring to book rental history of other users that have high similarities with the target user. Finally, user evaluation was conducted for the three models using the derived evaluation metrics. Each of the three models recommended five books to users who can either accept or reject the recommendations as the way to evaluate the models.

Abstract

This study constructed an ontology targeting journal articles and evaluated its performance. Also, the performance of a triple structure ontology was compared with the knowledge base of an inverted index file designed for a simple keyword search engine. The coverage was three years of articles published in the Journal of the Korean Society for Information Management from 2007 to 2009. Protégé was used to construct an ontology, whilst utilizing an inverted index file to compare performance. The concept ontology was manually established, and the bibliography ontology was automatically constructed to produce an OWL concept ontology and an OWL bibliography ontology, respectively. This study compared the performance of the knowledge base of the ontology, using the Jena search engine with the performance of an inverted index file using the Lucene search engine. As a result, The Lucene showed higher precision rate, but Jena showed higher recall rate.

본 연구는 대학생의 이메일 기록관리 행태와 대학 이메일 정책에 관한 인식을 파악한 것이다. 이를 위해 국내 대학에 재학 중인 대학생 317명을 대상으로 이메일 기록관리의 필수요소인 이메일 공통사항, 작성, 관리, 보존, 인식, 총 5가지 항목으로 구성된 설문조사를 실시하였다. 또한 대학의 이메일 서비스 제공 방법에 따라 구글을 이용하는 대학, 마이크로소프트를 이용하는 대학, 자체 웹메일을 이용하는 대학, 총 3가지 유형으로 나눠 6명을 심층 면담하였다. 조사 결과 대학생은 이메일을 주소록, 클라우드 스토리지, 파일 저장, 협업 도구로 사용하고 있었고 기록생애주기에 따라 이메일을 체계적으로 관리하는 데에는 어려움을 겪고 있었다. 또한 모바일 서비스 및 첨부파일 보존에 한계가 있는 대학 자체 웹메일보다 부가기능의 사용이 가능한 외부 이메일 플랫폼 이용을 선호하는 경향이 나타났다. 이러한 대학생의 이메일 기록관리를 지원하기 위해 졸업생 이메일 계정 유지, 충분한 이메일 저장 공간 제공, 대학생 대상 이메일 기록관리 교육 및 가이드라인 제공 등을 제시하였다.

Abstract

This study examines email records management patterns of undergraduate students and their perceptions of university email policy. The research collected data from 317 undergraduate students using a survey based on the five essential elements of email records management: common elements, email creation, email management, email preservation, and perception. Also, an in-depth interview was conducted with 6 undergraduate students, according to the method of university email service: Google, Microsoft, and in-house webmail. As a result, undergraduate students used email as an address book, cloud storage, file storage, and collaboration tool, and they had difficulties in systematically managing the email records according to the records lifecycle. Also, there was a tendency to prefer using an external email platform that can use additional functions to in-house webmail that has limitations in mobile service and preservation of attachments. Thus, this study suggests ways to help undergraduate students manage their email records, including maintaining graduates’ email accounts, providing sufficient email storage, and providing email records management training and guidelines for undergraduate students.

본 연구는 모바일 건강 어플리케이션의 사용을 방해하는 요인을 혁신확산이론에 따라 분석하고자 하였다. 본 연구는 유의적 표집방법에 따라 비수용자(non-adopters)와 사용 중단자(rejecters)로 구성된 대학생을 모집하였다. 연구 참여자는 총 44명으로 남학생 32명과 여학생 12명으로 구성되었으며 서면인터뷰를 실시하였다. 연구 결과, 상대적 유익성, 복잡성, 시험가능성 및 관찰가능성 등과 같은 속성은 건강 어플리케이션의 채택이나 지속적 이용을 방해하는 심각한 요인으로 작용하지 않았으나, 상대적 불이익과 적합성은 커다란 방해요인으로 작용하는 것으로 파악되었다. 본 연구의 결과는 건강 어플리케이션이라는 혁신을 확산시키고 지속적 이용을 장려하기 위해서는, 상대적 유익성이나 복잡성을 개선하기 보다는, 상대적 불이익에 대한 인식을 재고하고 생활 적합성은 강화해야 한다는 점을 시사한다.

Abstract

The purpose of the study is to identify the barriers to using mobile health applications based on the Diffusion of Innovations Theory. The study employed a purposive sampling to recruit college students who were non-adopters or rejecters. The study participants were a total of 44 students, who consist of 32 males and 12 females, and paper-based interviews were conducted. The findings of the study indicated that attributes such as relative advantages, complexity, trialability and observability were not considerable factors of impeding the adoption or continuous use of health applications, whereas relative disadvantages and compatibility were. The study suggests that health application developers and service providers minimize relative disadvantages and enhance compatibility of the innovation with consumers’ life styles, rather than try to improve relative advantages and complexity, to more effectively encourage non-adopters to try and maintain using the innovation.

Abstract

This study aims to understand students’ perceptions of the spatial characteristics of school libraries when they use them for reading. We selected a set of spatial characteristics by reviewing the literature and conducting a preliminary investigation. Then, we examined how students perceived the importance of and how satisfied they were with each characteristic. In addition, we investigated how students’ perceptions differ by the library uses and reading-related activities. We also studied whether the satisfaction of school library users affects their continued use of the libraries. We also verified whether school library user satisfaction is an intervening variable in continued-use intention, which is affected by spatial characteristics perception. We conducted a survey of 342 students from four middle schools. The analysis of the survey outcomes shows differences in library use due to spatial characteristics such as convenience, communicability, diversity, and safety. Factors such as communicability, comfortability, and ambience affected user satisfaction positively. Both aesthetics and communicability also positively influenced the continued-use intention. Furthermore, we identified that communicability, comfortability, and ambience eventually impacted the continued-use intention via user satisfaction, an intervening variable. The significance of this study is that it considered the direction of the school library to support students’ reading by regarding the school library as a space for reading.

Abstract

The purpose of this study is to investigate the characteristics of indexes by human and machine, and differences between them in terms of term identification in a fulltext environment. A back-of-book index and two indexes produced by two term identifiers (LinkIt and Termer) as pseudo-indexing systems for a whole body of a monograph are examined. In the investigation, the traditional contrast between manual and automatic indexing is confirmed in fulltext environment; manual index is for browsing and human use, and automatic index is for searching and machine use. The border between them, however, becomes vague. Some considerations for the use of the term identifiers for browsing and for searching are discussed, and further research for the use of the term identifier is suggested.
