We present steganographic service model and algorism that fit feature of streaming audio book service in order to hide information of copyright and certificate of it. Secret information is encrypted with random numger by secret key that client and server share, so that increase confidentiality. We made secret data distributed randomly and evenly, and improved throughput by simplifying additional computations considering streaming environment.

e-book is digital contents using IT technology instead of paper. It is carried in Internet and displayed wish Viewer of PC, PDA or terminal. The Open eBook specification is to provide a specification for representing the content of electronic books to these viewers. The specification is based on HTML and XML, the same core languages that define the World Wide Web, and is designed to allow publishers and authors to deliver their material in a single format. In this paper, we design and implement the viewer that can support OEB(Open eBook) standard. Viewer is composed parser part and display part. In audition, we add some functions - the book shelf, the bookmark and the dictionary - for convenience of readers.

This study is about e-Book program based on human-computer interaction(HCI) system for physically handicapped person. By acquiring background knowledge of HCI, we know that if we use vision-based interface we can replace current computer input devices by extracting any characteristic point and tracing it. We decided betweeneyes as a characteristic point by analyzing facial input image using webcam. But because of three-dimensional structure of glasses, the person who is wearing glasses wasn't suitable for tracing between-eyes. So we changed characteristic point to the bridge of the nose after detecting between-eyes. By using this technique, we could trace rotation of head in real-time regardless of glasses. To test this program's usefulness, we conducted an experiment to analyze the test result on actual application. Consequently, we got 96.5% rate of success for controlling e-Book under proper condition by analyzing the test result of 20 subjects.

New business The e-book industry is creating a convergence of ICT and printing culture. Even so, the system changes is not great in Korea. Global market players are going to creating a membership or community-type business model to take advantage of the terminal, platform, network, but the creative content production in Korea is limited. Since the discussion is limited to such devices or network services most, we suggest the possibility of modeling a multi-faceted. And the development of technology and services platform content is also important as a strategic approach to the development of the e-book industry. Most of all, we propose the application of content, technologies and services are developed.

본 연구는 3차원 가상현실 e-book도서관 시스템을 설계하고자 한다. 제안한 시스템은 입체적 가상공간의 전자도서관으로 사이버 상에서 실제의 도서관을 방문한 것처럼 사용자 우호적 인터페이스로 자료를 관리/서비스할 수 있는 가상현실 전자도서관 시스템이다. 이 시스템은 문헌 정보에 대한 온톨로지 기반의 정보검색 에이전트로 개발되며, 온라인 서비스를 통한 3차원 가상현실에서 도서관을 네비게이션으로 이동하면서 문헌을 검색할 수 있다.

디지털 교과서 상용화 시범 사업은 다양한 학습 지원 도구들과 사회 각 분야의 최신정보, 지식DB등을 활용하여 교실에서 참여형 학습을 실행할 수 있는 사업이다. 현재 디지털 교과서는 유통되고 있는 페이지 단위의 e-book형태가 아닌 확장 가능 구조로 개발되어 있어, 기존의 e-book 단말기나 e-book reader 프로그램에 바로 적용할 수 없다. 본 연구는 이러한 문제를 해결하기 위해 디지털 교과서 단말기의 요구 사항과 기존 단말기의 구현기능을 분석하여, 개선된 단말기의 기능과 규격을 제시하고, 이를 활용할 수 있는 교실 교육 환경을 제안한다.

The terminals of e-Book(electronic Book) are classified into two types which consist of special-purpose terminal equipment and general-purpose terminal equipment. Although the terminal products inr the two types have had a strong race in the e-Book market each other, both enterprises and consumers want the two type to remain persistently with competition in good faith. Therefore, it is necessary for each type camps to find blue ocean by establishing differentiation strategies of each type. In this paper, we designed the research model that independent variables consist of hardware quality and software quality, dependent variable is user satisfaction, moderator variable is the terminal type. Through the research model, we investigated factors having a influence on the user satisfaction of the e-Book terminal that consists of hardware and software. In particular, we investigated if the degree of the influence is different between the two types. As a result, we got conclusions as followings. First, the quality of hardware and software in the terminal had significant influences on the user satisfaction. Second, the degree which the hardware quality has influenced user satisfaction was not different between the two types, but the degree which the software quality has influence on user satisfaction was different between the two types. As a implication of this result, we found that special-purpose terminal provider need to establish a strategies for raising the quality of e-Book viewer to provide different product from general-purpose terminal.

This study selected and utilized the 'Naver post' as an e-book production tool to be used for learning. The production of such SNS format e-books aimed at founding out its effect on learning attitude and academic achievement by stimulating interest and confidence in the learning of the students. To accomplish such an aim, the study selected 50 students from two classes in the fourth grade of a public elementary school. One class of 25 students went through a social studies lesson that applied SNS type e-book production activities, and the other class of 25 students underwent a regular social studies lesson as the comparative group. The major results of the study's analysis is SNS type e-book production did not significantly improve academic achievement in social studies, but SNS type e-book production significantly improved the learning attitude during social studies.

The purpose of this study was to assess the perception of e-book subscription services among the digitally native generation in their twenties, who have a high e-book usage rate. This study employed a mixed-methods approach, combining survey responses and usability testing. It aimed to assess the awareness and usage of e-book subscription services among university students in their twenties, a demographic known for their high utilization of electronic devices and e-books. The survey was conducted among 202 university students, and the responses were categorized and examined based on whether they were users or non-users. As a result of the survey, I found there is different awareness of e-book between users and non-users, on the other hand, convenience and portability are the strong point of e-books for users and non-users commonly also. Usability testing was performed on a group of 10 university students in their twenties who had not previously used the 'Millies Library' application, which is renowned as the most widely-used e-book platform. Following the experiment, participants expressed positive feedback regarding various optional features, convenience, design, and cost-effectiveness. However, they also had negative reactions concerning touch errors, malfunctions, functional practicality, a lack of interest, system issues, and the absence of a library.

The objective of this study is to move the initiative of children's electronic books from portal sites to libraries and to help improving libraries' information services through their systematic study. The present use state of an e-book site for children that is currently serviced by A-academic library was mainly analyzed for the study. The desirable acquisition policies were also suggested for the activation of the juvenile e-book services for libraries.
