By virtue of diverse advantages derived from digital media, eBook is getting started to use. And many market research agencies have predicted that its market will be greatly expanded soon. But against those expectations, copyright-related problems and the difficulties of its accessing inherited from various eBook content formats become an obstacle to its diffusion. The first problems can be solved by DRM technology. And to solve the second problems, each nation has published its own content standard format. But the domestic standards are useful only the domestic level, they still leave the problems in the national level. The variety of content formats has created a demand for mechanisms that allow the exchange of eBook contents. Therefore we study the mapping relations between eBook contents for conversion. To define the mapping relations, first we extract the mapping both between eBook contents and between normal XML documents. From those mappings, we define seven mapping relations and classify them by cardinality. And we analyze the classified relations, which can be generated by automatic, or not. Using these results, we also classify the eBook content conversion as automatic, semi-automatic, and manual. Besides, we provide the conversion templates for mapping relations for automatic generation of conversion scripts. To show the feasibility of conversion templates, we apply them to the eBook content conversion. Experiment shows that our conversion templates generate the conversion scripts properly. We expected that defined mapping relations and conversion templates can be used not only in eBook content conversion , but also in normal XML document conversion.

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.

Many countries have established eBook standards adequate to their environments. In USA, OEB PS is announced for distribution and display of eBooks, in Japan, JepaX is announced for storage and exchange, and in Korea, EBKS is made for clear exchange of eBook contents. These diverse objectives lead to different content structures. These variety of content structure will cause a problem in exchanging them. To correctly exchange eBook contents, the content structure should be considered. So, In this paper, we study conversion methods of standard eBooks contents based on Korean eBook standard, with contemplating content structure. To convert contents properly, the mapping relations should be clearly defined. For this, we consider standard's structure and extension mechanisms, and use path notations and namespaces for precise description. Moreover, through analysis of each mapping relationships, we classify conversion cases into automatic, semi-automatic, and manual conversions. Finally we write up conversion scripts and experiment with them.

Portable devices are growth such as smart phone and smart pad and e-book market is also growing, but existing publishers have some problem of conversion paper book to e-book with technology. In this paper propose to solve this problem using HTML5 for E-book making tool. HTML5 is new version of HTML. It can be use video and audio element. Also a lot of web Browser can be use HTML5 format. If we have HTML5 compatible browser devices, we can use anywhere and anytime. We propose video book making tool using these HTML5 characteristics, it is available to support of text or images.

To access PDF documents on an electronic book, PDF documents need to be converted into EPUB which is a standard format of the electronic book. When converting a PDF document into EPUB format, we need to convert color representations from CMYK into RGB representation. It is possible to give a visual effect and a user interaction using a video and JavaScript supported by EPUB format. The schemes for converting from PDF to EPUB are studied in this paper. (1) The first study is to carry out not to lose the color conversion effect using an ICC profile. (2) The second one is a layout configuration in the conversion process. (3) The third one is to highlight a specific content such as quiz platform to provide interactive visual effect for electronic book readers. Finally, in this paper we will show the usability of EPUB based eBook converting scheme through user study.

Large amounts of research results are being produced with the rapid growth of science and technology. The current method for constructing the database was way too time and cost consuming. In the currently upcoming technology and knowledge society, web service is required to provide the various professional service for national R&D reports. A process to manufacture E-Book for professional service is also required. This research shows the conversion models with efficient manufacturing process and the systems related to the development through defining the National R&D reports.

전자책 (E-Book)에 대한 수요가 커짐에 따라서 전자책 시장이 점점 커지고 있다. 이에 PDF 와 같은 다른 형태의 문서들을 전자책으로 변환하는 프로그램 및 서비스들에 대한 요구가 늘어가고 있다. 전자책의 공급 규모가 커지고 형식이 발전함에 따라서 대규모의 전자책들을 빠르고 효율적으로 변환 가능하게 하는 환경의 조성이 필요하게 되었다. 기존 시장에 배포되거나 출판된 PDF형식의 문서를 오픈소스 변환 라이브러리를 이용하여 변환할 수 있는 변환기를 작성하고, 이를 이용해 대규모 PDF 를 저장하고 있는 분산 저장 시스템에서 백그라운드 배치 작업으로 변환할 수 있는 구조를 설계 및 제안한다. 본 논문에서는 전자책의 효율적인 변환을 위한 분산 환경에서의 작업 배분방법을 다룬다.

The Korea government has recently announced "A Master Plan for Smart Education", including application of digital textbooks and composition of education system using cloud computing. Our education system in future circumstance, over the conventional e-learning methods, needs the smart education solutions which enable students to study and communicate on various types of devices. The ongoing government project related with the digital textbook has been performed as mid- and long-term goals, whereas PDF-based e-textbook project, similar to e-book model and, has been already completed for the short-term goal. For the purpose of improved future smart education circumstance, however, a specific strategy is required in the following areas: flexibility of format conversion and independency of original text sources among the multiple device platforms. Therefore, in this paper, we propose a standardization scheme for e-textbook format based on e-book structure. To do this, we survey trends in e-book technologies, and research on standardization of e-book format for digitalization of textbooks, based on the analysis of existing textbooks. Moreover, we produce an example e-book content using our proposed standard method. As a result, our approach can be applied to the future smart education circumstance, and we may say that it will be efficiently applicable to the long-term digital textbook project.
