본 연구에서는 온라인 다중 사용자 환경의 eBook annotation 시스템 개발에서 데이터를 의미 기반으로 관리하고, 데이터에 대하여 상호 공통적인 이해를 표현하며, 그리고 데이터에 대한 무결성 검사 등을 지원하기 위해서 eBook annotation 온톨로지를 설계하였다. eBook annotation 데이터에 대한 상호 공통적이 이해를 표현을 위해서 한국 전자책 문서 표준인 EBKS(Electronic Book of korra Standard)를 기반으로 설계하였으며 설계된 온톨로지는 Conceptual Graph(CG)를 사용하여 표현하였다. 의미 기반의 처리를 위해서 본 온톨로지에서는 동의어(Synonym) 관계와 다국어(Interlingua) 관계를 고려하였으며 또한 annotation 데이터 생성시 오류 방지와 중요도를 표현하기 위해서 integrity, important axiom을 고려했다. 제안된 온톨로지는 annotation 데이터의 재사용성을 높일 수 있고 의미 정보를 활용함으로써 eLearning, cyberclass과 같은 다중 사용자 환경에서 효과적인 협업을 가능하게 한다.

Recently, interests on e-book (electronic-book) have been increasing since e-book can provide many benefits than traditional books can do. Especially, e-book can be attractive for elementary school students due to its interaction provided by various multimedia tools. However, despite the fact that the numbers of elementary school students using e-book have been increasing, researches on e-book have not made a significant progress. Also since most researches on e-book have been concentrating on fairy tale books without considering interaction, the true virtue of e-book has not been maximized. Taking this into account, this study is intended to suggest an e-book design model for elementary school students with interaction among learners reinforced. In this study, first, existing e-book design models are analyzed in terms of interaction. Based on this analysis, an e-book design model is designed and developed. The proposed model can help learners interact within their learning levels, support with many functions such as interchangeable help function, various search instruments, previews, messenger functions, and provide a book-like environment where learners themselves can take initiative in learning.

The U.S., Japan and Korea have realized the importance of establishing standards for eBook document formats and with government bodies, related industries and academic circles, OEB PS, JepaX and EBKS were established. However, compared to OEB of the U.S. and JepaX of Japan, EBKS contains different objective for establishment and different structures. As a result, for converting between documents of different standards, exact analysis of the document structures are called for and minimization of information loss when actually converting documents is required. Therefore, a method for explicit exchange between documents of different standards minimizing document structure is proposed and examples are looked at. As a result, in this paper, conversion possibilities between EBKS and OEB/JepaX are introduced and the result can be applied to cases when exchanging eBook standards and other formats.

본 논문에서는 내장형 리눅스 환경에서 XML기반 EBKS용 전자책 리더 개발에 대한 내용이다. 개발된 단말기는 내장형 리눅스 타겟보드에서 한국형 전자책 문서 표준에 기반한 XML 문서를 Qt SAX 파서를 이용하여 파싱하고, 크로스 플랫폼형 윈도우 시스템인 QWS(Qt windows system)를 이용하여 디스플레이한다. 개발된 전자책 리더는 리눅스 환경 뿐만 아니라 다양한 윈도우 플랫폼에서 신속하고 쉽게 개발 가능하며 SAX 파서를 사용하므로 DOM 인터페이스에 비해 메모리를 적게 사용한다.

The digital app-book is an advanced form of the electronic book (e-book), which attracts a lot of interests by the help of video, sound, sensors and a variety of interactions. As mobile devices have evolved, the demand of digital app-books is also rising substantially. However, the distribution of digital app-book contents is hard to meet the demand because the digital app-book requires a lot of programming cost for the interaction. To resolve this problem, Was verified and implementation as a library function of the interaction between device and user. The proposed library consists of three parts (user action recognition, device action, and content action) and provides various user-device interaction functions by combining methods of each part, which can support source code reusability, easy understanding and availability, and wide expandibility. The library was used in the development of natural science education app-book contents. As a result, it could reduce a lot of code lines and facilitate more rapid app-book development.

Libraries have a variety of resources due to the endless changes of the library environment. Electronic resources have become the one of the important library resources. As an electronic resource, e-Book has emerged recently and is worth of notice to be a great resource in the libraries. This study reviews the history and special features of the e-Book. This paper analyzes the functions and problems of e-Book and changes of the library services related e-Book. The purpose of the study is to point out the problems and suggest the possible solutions of e-Book usages in the university libraries by the survey.

This study describes the humanistic perspective inherent in Korean Buddhism. It is based on a narrative of the establishment of Haeinsa Temple, which is one of the three major Korean traditional temples, and represents the heritage of Korean Buddhism. With this narrative, we developed and implemented mobile content for Android devices titled "Treasures from the Palace of the Dragon King". Its scenario, which is a folktale of the establishment of the Haeinsa Temple, was created using A.J. Greimas' Actantial model as the research method. As a result, the content developed by the reconstruction of the scenario consists of mini-games and animations offering an intuitive user experience (UX), which is implemented in a compound E-BOOK for mobile devices. We aim to promote Korea's traditional culture throughout the world, using this content as a starting point for the future.

As the eBook market grows fast recently, various eBook viewer solutions such as hardware viewers and software readers came out to the market. We can, however, hardly find mobile eBook interfaces for the reading disabled people who have difficulties in reading for their visual impairment or learning disabilities, or dyslexia. An eBook viewer interfaces for the reading disabled people should be carefully and distinctively designed because the reading disabled people cannot use normal versions of eBook viewer. In this paper, we suggest a eBook viewer interface model to make the reading disabled people read eBooks easily. Depending on the type of the reading disabled people: the full blind, the almost blind, the just learning disabled, our model provides an adaptive interface to make them read eBooks effectively. In addition, unlike the existing simple audio books, we also support annotation systems to make the reading disabled people interact with eBook viewer. To show the effectiveness of our model, we implemented an eBook viewer prototype on an android-based mobile device. We are sure that our model and implementation can make the reading disabled people, who is 10% of all the domestic people, read eBooks effectively.
