With the proliferation of the e-Book industry, people are increasingly interacting with e-Book as information systems. While e-Book contains the components regarded as an information system(IS), few studies have been conducted to assess the success of e-Book from IS perspective. This study proposed and empirically evaluated an e-Book success model. Structural equation modeling techniques were applied to the data collected by questionnaire from 241 users of e-Book. Every relationship among constructs was significantly supported by the data. This finding provided theoretical implications to extend existing e-Book research into the broader IS research area. Furthermore, this study illustrated the use of multi-group structural analysis to test the differences in structural weights between high e-Book and high paper book utility groups. The managerial implications of the results in setting different relationships and allocating appropriate paths to vitalize the e-Book market were discussed.

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.

The e-book technology is developing day by day with the expansion of e-ink technology. However, consumers' complaint over contents which are relatively deficient compared to paper book, the issue of compatibility of file between bookstores is not improved as yet. This means that present e-book market needs study in the viewpoint of consumer who intend to accept requirement of market instead of viewpoint of technical development. Thus, this study intends to measure the quality of three main attributes such as system, contents and service based on IS Success Model which compose e-book to identify the influence on readers' purchase intention. Result, System quality is to device purchase intention, and Contents quality is to e-book pruchase intention, it showed a significant damaging effect on.

Business environment is shifting from industrial economy to knowledge based economy. Enterprises go through numerous trials for successful management in changing environment. Along with trial tests, research area has been growing simultaneously. Unlike initial research which focused on basic concepts such as: form of business model and success points. Current research emphasizes on actualization of business that enterprises plan, which brought academic research with perplex form of knowledge structure. On the other hand, there is limitation in understanding business model systematically due to preceding research primarily centered on analyzing definition and case study. In order to analyze knowledge structure, this study utilized social network analysis based on "relationship". For the analysis, 13,412 keywords were extracted from 36years worth of article or research related to business model stored in SCOPUS database. From the analysis, it was shown core research subject was INNOVATION and the number of co-authors has increased due to the academic diversity. Business model research is divided into five sub-categories (E-commerce, SMEs, sustainability, open-source, and e-book). Through cognitive map analysis on each of research characteristics of sub-category, it has shown that E-commerce, SMEs, sustainability, and open-source are core categories.
