This study investigates how librarians view library user privacy. To this end, a four-part survey was conducted: respondents' opinions about the privacy of library users, the degree to which library records violate the users' privacy, the role libraries and librarians fulfill to ensure user privacy protection, and librarians' need for privacy education. Results showed that librarians were very aware of privacy issues, but they perceived that library users' privacy awareness was not high. In particular, they had little knowledge of what library records or which library tasks might have the potential to violate users' privacy. In addition, awareness efforts of librarians to ensure user privacy was very low. On the other hand, the need for library user privacy educational programs was shown to be very high, and the willingness to participate was also relatively high.

Visitors who browse the web from wireless PDAs, cell phones are frequently frustrated by interfaces. Simply replacing graphics with text and reformatting tables does not solve this problem, because deep link structures can still require more time. To solve this problem, in the paper we propose an algorithm, Minimal Path Algorithm that automatically improves wireless web navigation by suggesting useful shortcut links in real time. In the result of this paper, Minimal Path algorithm offer the shortcut and the number of shortest links to web users.

본 연구는 한국 공공도서관의 소셜 미디어 마케팅이 실제로 어떤 효과를 나타내고 있는지를 실증적으로 검토하기 위해 수행되었다. 분석에는 공공도서관의 2012년 트위터 사용 데이터, 국가도서관 통계를 사용하였다. 트위터를 활용한 그룹과 활용하지 않은 그룹 간의 대출량 및 이용자량 변화에 대한 t검정, 트위터 활동 데이터와 대출량 및 이용자량 변화 간의 선형 회귀분석이 수행되었으며, 그 결과 두 분석 모두 유의한 결과를 도출하지 못하였다. 이를 기반으로 표본 문제, 트위터 계정 활용 문제, 성과 지표 문제를 제시하였다.

This study investigated whether academic library user education contributes to promote users' information literacy. 39 students of Duksung Women's University participated voluntarily for this experiment. A test questions set about locating specific library materials was delivered to participating students, who were to find right answers for each test question. Their answers about test questions were measured in terms of success rate, time used to solve each problem. Self evaluation scores were also collected before and after giving them user education. Academic library user education significantly contributed participating students' ability to locate academic library materials through a library user interface. After receiving user education students were able to solve more successfully test questions, use less time for each question, and evaluate themselves more highly in terms of information utilizing ability. The effectiveness of the academic library user education was lasted for about 8 weeks after the education they received.

The paper presented not only the difference of the marginal walking time by passenger. but also the derivation of the bus service determination model by passenger attributes. The marginal walking distance to bus stop is a basic parameter to estimate bus service coverage area in certain area. And the marginal walking distance could be transformed from the marginal walking time, which is the focus of this paper. The result of analysis revealed that the age and income of passenger are strongly related to the marginal walking time. In planning or regulating the spacing of bus routes or bus stops in certain area, the model suggested in this paper help for the planner to choose optimal alternative.

기하급수적으로 늘어나는 인터넷상의 정보, 이를 이용하는 이용자의 증가와 더불어 웹 탐색도구의 수도 그만큼 증가추세에 있다. 웹 탐색도구가 1994년 처음 개발된 이래 이제까지 웹 탐색도구의 개발자들은 개발자체에 초점을 맞추어왔다. 그러나 성공적인 시스템은 시스템의 자체성능도 중요하지만 이를 이용하는 이용자들이 이해하기 쉽고 이용하기에 편리한 웹 탐색도구로 개발하는 것은 시스템의 효용성 측면에서 더욱 중요한 문제이다. 이에 본 연구는 계명대학교 학생을 대상으로 각 유형별로 가장 잘 그 유형을 대변하는 탐색도구를 선정하여 이를 직접 탐색케 함으로써 이를 토대로 웹 탐색도구를 이용하는 이용자그룹간의 이용능력과 이용행태 및 그들의 평가를 분석하였다.

모바일 광고는 무선 디바이스의 발달로 인해 새로운 광고 수단 및 마케팅 수단이 되었다. 많은 이용자들이 무선 인터넷을 사용하고 있으며, 앞으로도 사용자는 증가할 것으로 보여진다. 그러나 무선 서비스는 단순한 SMS 형태의 서비스가 대부분이며, 이러한 SMS를 수신하는 이용자들은 자신이 원하지 않는 광고성 메시지의 수신 대해 상당한 거부감을 가지고 있는 것으로 조사되었다. 따라서 이러한 문제를 해결할 수 있는 광고 중계 모델 "ATPA" (Advertisement Transport Processing Architecture)을 제안한다. "ATPA"는 필터링 기법을 응용하여 고객 지향적인 모바일 광고 시스템으로서 이용자는 자신에게 적합한 광고의 수신하게 하고, 광고주는 이용자의 특성에 따른 차별적인 광고를 제공할 수 있다.

The author discusses the nature and scope of archival reference service through the debate to user studies in the 1980s and the 1990s. Until the 1990s, archivists paid little attention to studying their user population. A new approach to archival user service led to the development of various public services of archives and resulted in active interaction with the public. Based on the discussion, the article examines the implication of archival reference service in Korean society.

In accordance with the development of broadcasting, the style of using medium by users has been personalized in the propensity to consume. Recent advent of media convergence allowed users of medium to decide the received environment for their needs, thereby the position of users has become more important in the medium consumption. IPTV has the most advanced form of personalized information media. However, IPTV was made by media convergence, which has relation with a variety of interested parties, so there are a few troubles among them in the way of commercializing IPTV. As a matter of fact, although users play a leading role in the IPTV industry, there are still few discussions on the welfare of users. IPTV should be remained the characteristic of the medium of personalized information, and it should include the welfare of users in various fields of media convergence. That is Universal Service. It is necessary to be guaranteed the access right and the variety of contents in using IPTV. Moreover, in terms of telecommunication, IPTV should insure the reasonable fare system as a pay-services. On the basis of the analysis in local and international IPTV circumstances, in terms of content as a medium of personalized information, in terms of fares as a pay-services, and in terms of digital literacy as a new medium of digital access, policies for welfare of users are suggested.

The multi-class traffic assignment problem is the most typical one of the multi-solution traffic assignment problems and, recently formulation of the models and the solution algorithm have been received a great deal of attention. The useful solution algorithm, however, has not been proposed while formulation of the multi-class traffic assignment could be performed by adopting the variational inequality problem or the fixed point problem. In this research, we developed a hybrid solution algorithm which combines GA algorithm, diagonal algorithm and clustering algorithm for the multi-class traffic assignment formulated as a variational inequality Problem. GA algorithm and clustering algorithm are introduced for the wide area and small cost. We also performed an experiment with toy network(2 link) and tested the characteristics of the suggested algorithm.
