To improve the conventional illustrated fish book, this paper introduces the concept of an electronic illustrated fish book which applies IT techniques to the conventional one, and proposes the image retrieval for it. The image retrieval is a core technology of the electronic illustrated fish book and make it overwhelm the conventional one. Since fishes, even if the same kind, have different features in shape, color, and texture and the same fish can even have different features by its pose or environment at that time for taking a picture, the conventional image retrieval, that uses simple features in shape, color, and texture, is not suitable for the electronic illustrated fish book. The proposed image retrieval adopts detail shape features extracted from head, body, and tail of a fish and different weights are given to the features depending on their invariability. The simulation results show that the proposed algorithm is far superior to the conventional algorithm.

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.

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.

현재 전자책 (E-Book : Electronic-Book)에 대한 관심은 크게 증가하고 있으나, 아직까지 전자책에 대한 연구와 개발은 미미한 실정이다. 또한 대부분의 초등학생용 E-Book은 상호작용성을 고려하지 않아 E-Book의 장점을 살리지 못하고 있다. 따라서 본 논문은 상호작용을 강화한 초등학생용 E-Book 설계 모형을 제안하였다. 본 연구는 기존의 초등학생용 E-Book을 상호작용의 측면에서 분석하여, 이를 바탕으로 학습자의 수준에 적절한 통제하에서 상호작용을 돕기 위한 정보를 제공하고, 교환할 수 있는 도움말, 다양한 검색도구, 미리보기, 메신저 등의 기능을 지원하며, 또한 종이책과 같은 친밀한 환경에서 자기 주도적인 학습을 제공하는 E-book을 설계하고 구현하였다.

Electronic books offer various possibilities for expanding access as well as changing reading behavior in our life. However despite the considerable promise of e-book, e-book market was not vitalized than re expected. This study investigated the current e-book environment and suggest some guidelines for making e-books a viable part of libraries' collections and our reading life. Findings and issues about the status of the current e-book market and technologies, and some experience of libraries in the advanced countries give us a lesson for the Korean library societies.

This paper is studied in order to develop the models that are appropriate for the procurement of electronic books at the school libraries. To develop the model, the following factors were reviewed: the characteristics of an electronic book, the factor analysis that affect the electronic book price, use case, environment, the role of government for the price decision model and procurement method. The models were proposed based on the above analysis and review. In addition, the proposed models reflect various opinions that the school libraries can apply.

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 공통적인 이해의 표현을 위해서 한국 전자책 문서 표준인 EBKS(Electronic Book of Korea Standard)를 기반으로 설계 하였으며 설계 된 온톨로지는 Conceptual Graph(CG)를 사용하여 표현하였다. 의미 기반의 처리를 위해서 본 온톨로지에서는 동의어(synonym) 관계와 다국어(multilingua) 관계를 고려하였으며 또한 annotation 데이터 생성시 오류 방지와 중요도를 표현 하기 위해서 무결성 검사, 중요성 axiom을 고려 했다. 제안된 온톨로지는 annotation 데이터의 재사용성을 높일 수 있고 의미 정보를 활용함으로써 eLearning, cyberclass과 같은 다중사용자 환경에서 효과적인 협업을 가능하게 한다. 본 연구에서 구현한 eBook annotation 시스템은 설계한 온톨로지를 이용함으로써 의미 기반의 데이터 관리가 가능하다. 또한 annotation 생성 시 온톨로지 구조를 모르더라도 annotation을 생성할 수 있는 인터페이스를 구현하였다.

Because of today's rapid growth of digital contents market and many benefits of electronic book, many people have considerable interest in E-book. Furthermore multifarious consortiums take an active part in standardization of I-book, and many E-book tools have been provided by software manufactures all over the world. E-book tools include editor for production of E-Book, viewer for reading, and the like. Especially in E-book viewer, annotation function has to be Included to put arrangement, summation, recording, comment, emphasis and after comprehension to practical use. In this paper, a E-book viewer with annotation is designed according to the specifications of EBKS, Korean standard. The proposed viewer is aimed to implement in PDA with embedded Linux, but developed in Windows 2000 platform. Because development environment and application environment are different each other, Qt-Library and cross-compiler are used for cross-platform development. The viewer support various functions such as adjusting of font size, hypertext linking, retrieval of specific word, and so forth. And in addition to these basic functions, annotation function is designed for the viewer, which can be used for re-usage and sharing of important information.

As the improvement of computer performance and the development of IT technology have influence upon publishing industry, the e-Book system, a type of electronic resources, has come out. This is a method to use both texts and 2D image illustrations. Nowadays, there are more and more users who want high quality contents and a variety of contents such as the illustrated fish book using the 3D system. This article adds 3D animation objects to the current e-Book system and designs and realizes the 3D fish simulation system to which e-Book technology is applied so as to improve the comprehension of texts and readability of detailed information and increase readers' immersion as well.
