There has been a significant paradigm shift in the book industry from print to digital, with the increased use of electronic books (e-books) on e-book readers. The major online booksellers and publishers are devoting their energies to the growth of the e-book market, resulting in an upward spiral in e-book usage, and a resultant increase in the number of downloaded e-books in an e-book reader library. However, there are comparatively few features for e-book management and search in most e-book reader libraries, particularly in smartphone environments. In addition, the user interfaces of e-book management in e-book readers are highly diverse, which has led to major usability issues. In this paper, we analyze user preferences for e-book management and search in the libraries of the five most commonly used e-readers for the Android smartphone platform via a questionnaire survey. Then, we suggest ideal alternatives in addition to user-friendly features based on user preferences for managing e-book libraries, to allow users to more easily browse collections, thereby enhancing the usability of e-book readers.

The proliferating use of e-journals has led increasing interest in collecting and analyzing usage statistic information. However, the existing manual method and simple journal usage reports provided by publishers hinder the effective collection of large-scale usage statistics and the comprehensive/in-depth analysis on them. Thus we have proposed a hybrid automatic method of collecting e-journal usage statistics based on screen scraping and SUSHI protocol. In addition, the generation method of summary statistics presented in graphs, charts and tables has been suggested in this study. By utilizing the suggested system and analysis data, librarians can compose various reports on budget or operation of the libraries.

한국도서관협회(회장 이두영)는 9월 24일부터 3일간 경주교육문화회관에서 '전국도서관대회'를 개최했다. 신일희 총장(계명대)은 기조연설을 통해 시대적 사명에 복무했던 도서관의 영광을 재현할 것을 촉구했다. 그는 "도서관이 지식과 정보를 보급하는 것은 인류발전을 위해 수임받은 숭고한 사명"이라며 도서관 대중화를 위한 관계자들의 적극적인 노력을 요망했다. 특별강연과 주제발표, 세미나 등 모두 26편의 강연이 이뤄진 가운데 김포옥 교수가 주제발표한 (공공도서관장의 전문의식과 교육방향)은 앙케트를 바탕으로 도서관의 실질적인 운영자인 도서관장의 '전문가 의식'을 분석해 눈길을 끌었다. 김포옥 교수는 전국 도서관장 329명 중에 설문에 응한 188명의 응답을 바탕으로 근무경위.근무연수.사서교육이수 여부 등을 분석했다. 주목되는 대목은 도서관장의 34%가 사서자격증조차 없는 비전문가라는 점, 도서관장을 전문직으로 평가한 사람이 115명(61.2%)에 불과한 점 등이다. '도서관 일을 특별히 지망하지 않았다.'는 관장이 44%나 되어 애초부터 '전문가 의식'을 기대하는 것이 무리하는 추론도 도출했다. 김교수는 "도서관장의 전문가 의식을 키우기 위해 지속적인 교육과 직업만족도를 높이는 방안을 모색해야 할 것"이라고 주장했다. 제1주제 '도서관 정책' 방향을 모색하는 자리에서 한성택 교수(숭의여대) 등 3인은 21세기에 맞는 우리나라 도서관 정책의 기본 방향을 제고하고 도서관의 유기적 역할을 모색했다. 제2주제 '봉사'에 대해 채윤정 사서(정독도서관) 등 4인은 도서관의 서비스 실태와 향후 방향성을 논했으며, 제3주제 '운영'은 김포옥 교수(전북대) 등 4인이 도서관 운영의 현주소를 각각의 입장에서 조명했다. 마지막 주제는 '학교도서관' 활성화로, 김종성사서(부산대) 등 2인이 도서관과 학교 교육의 연계성, 학교도서관의 발전 전략 방안을 모색했다. 주제발표 논문 가운데 3편을 욕약해 싣는다.

Mobile applications are significantly impacting people's smart phone using behavior and mobile industry value chain. By examining sources of data on mobile applications use, this study presents evidence about what factors would affect the amount of apps download, which may be useful to guide app designers and publishers to develop more persuasive new apps and marketing strategies. The results indicated app ranking had effect on download amount of apps in both Android app market and Apple app store, while prices of apps had no impact on the amount of download. App type, developer experience, and locality had effect on the amount of download only for paid apps in Apple app store.

As the logistic environment of digital contents is rapidly changing, the protection of the digital rights for digital content has been recognized as one of critical issues. Digital Right Management(DRM) has taken much interest Internet Service Provider(ISP), authors and publishers of digital content as an interested approach to create a trusted environment for access and use of digital resources. This paper propose an interested digital rights protection scheme using license agent to address problems facing contemporary DRM approached : static digital rights management, and limited application to on-line environment. We introduce a dynamic mission control technology to realize dynamic digital rights management. And we incorporate license agent to on- and off-line monitoring and tracking. The proposed system prevent illegal access and use by using PBD security method real time action monitoring for user, data security for itself.

With rapid development of ubiquitous computing and location-based services (LBSs), human trajectory data and associated activities are increasingly easily recorded. Inappropriately publishing trajectory data may leak users' privacy. Therefore, we study publishing trajectory data while preserving privacy, denoted privacy-preserving activity trajectories publishing (PPATP). We propose S-PPATP to solve this problem. S-PPATP comprises three steps: modeling, algorithm design and algorithm adjustment. During modeling, two user models describe users' behaviors: one based on a Markov chain and the other based on the hidden Markov model. We assume a potential adversary who intends to infer users' privacy, defined as a set of sensitive information. An adversary model is then proposed to define the adversary's background knowledge and inference method. Additionally, privacy requirements and a data quality metric are defined for assessment. During algorithm design, we propose two publishing algorithms corresponding to the user models and prove that both algorithms satisfy the privacy requirement. Then, we perform a comparative analysis on utility, efficiency and speedup techniques. Finally, we evaluate our algorithms through experiments on several datasets. The experiment results verify that our proposed algorithms preserve users' privay. We also test utility and discuss the privacy-utility tradeoff that real-world data publishers may face.

Objectives : Final assessment of realized on forecasting studies of the literature sector on traditional Korean medicine (2000-2010) revealed results as follows. Methods : We investigated the related peer-reviewed papers and research project reports through Oriental Medicine Advanced Searching Integrated System(OASIS) of Korea Institute of Oriental Medicine(KIOM) and several publishers. Results : Of total five projects, two were realized and three were partially done. The projects 'It wil be standardized by establishing the concept of traditional Korean medical terms' and 'CDs containing traditional medicine books from China, Japan and Korea wiil be released' were decided to be realized. In addition to those, the projects 'Systematic database will be build up for TKM books', 'translation and annotation versions on TKM old books will be completed', and 'A wide range of literature related to traditional medicine of each Asian countries' were concluded to be partially realized. Five projects on predicting TKM in the year 2006-2007 analyzed in 1996 were evaluated as realized or partially realized. Likewise, the five predictions should be reviewed whether it will be necessary in the future after assessment on their realization. Conclusion : Furthermore, it should be studies if the new projects are needed for the future in addition to the existing challenges.

To deliver new products to market in a due time, companies often develop their products with numerous partners distributed around the world. Internet technologies can provide a cheap and efficient basis of collaborative product development among distributed partners. This paper provides a framework and its product database model that can support consistent product data during collaborative product development. This framework consists of four components for representing consistent product structure: the product configuration, assembly structure, multiple representations and engineering changes. A product database model realizing the framework is designed and implemented as a system that supports collaborative works in the areas of product design and technical publication. The system enables participating designers and technical publishers to complete their tasks with shared and consistent product data. It also manages the propagation of engineering changes among different representations for individual participants. The Web technologies introduced in this system enable participants to easily access and operate shared product data in a standardized and distributed computing environment.

In this study, we proposed the FRAD concept model of authority data schema for author, organization and journal titles included in the academic papers. Academic information includes author names, affiliations, publishers, journals and conferences. They are used as access points, and there are multiple relationships among these entities. It is expected that the use of authority data for academic information based on FRAD conceptual model could improve more accurate retrieval of information, systematic management of academic information, and various forms of knowledge representation. In this study, our entity-relationship authority data will be linked to the document, and included the several properties and relationship to identify the object.

The purpose of this research is to examine the characteristics and problems of the OASIS, an web archive, developed and operated by the National Library of Korea. An analysis of 55 websites collected in seven subject areas, including 'Philosophy', 'Religion', 'Literature', 'Social Sciences-Politics', and 'Technology-Technology' in the OASIS website shows the following problems: lack of balance in subject distribution, lack of authority or scholarly value of some contents, unclear application of selection criteria for personal creators/publishers, ambiguous definition of 'archiving', and inappropriate counting of collection and usage statistics. Some comprehensive and systematic efforts to improve the OASIS contents seem to be urgently needed.
