The requirement of automatic video summary is increasing as bi-directional broadcasting contents and various user requests and preferences for the bi -directional broadcast environment are increasing. Automatic video summary is needed for an efficient management and usage of many contents in service provider as well. In this paper, we propose a method to generate a content-based summary of linguistic educational videos automatically. First, shot-boundaries and keyframes are generated from linguistic educational video and then multiple(low-level) visual features are extracted. Next, the semantic parts (Explanation part, Dialog part, Text-based part) of the linguistic educational video are generated using extracted visual features. Lastly the XMI- document describing summary information is made based on HieraTchical Summary architecture oi MPEG-7 MDS (Multimedia I)escription Scheme). Experimental results show that our proposed algorithm provides reasonable performance for automatic summary of linguistic educational videos. We verified that the proposed method is useful ior video summary system to provide various services as well as management of educational contents.

Purpose: This study was conducted to develop case-based self-learning multimedia contents for preventing malpractice that frequently occurred among nurses working in the operating room. Methods: Based on the learning needs of operating room nurses, real case reports, and literature reviews, the case-based multimedia learning contents were developed according to the instructional design procedure. The assessment of learning needs was performed by the combination of surveys using structured questionnaire and of interviews for 40 operating room nurses. Results: The learning contents included four learning modules with real malpractice cases from the areas of operating preparation, nursing skills during operation, environmental management of operating room, and patient safety and observation-related. The 80 minute long case-based multimedia learning contents were finally developed after content validity tests from clinical experts. Each module contained photos, sounds and flash animation with voice recording on the contents of nursing error cases and standardized protocols. Conclusion: The developed multimedia learning contents based on real error cases in this study can be utilized as an educational hands-on training materials for nurses to prevent malpractice in the operating room.

In the era of Web 2.0, the digital contents are becoming major cultural subjects and the scope and added value of digital content technology industry keep increasing. In order to prevent thoughtless expansion of consumption oriented contents to the multimedia motion picture generation and promote the contents industry in educational, industrial or cultural aspect, educational contents should be specialized as strategic products with increased educational and entertaining meaning. As a result, this study analyzed characteristics of users regarding how educational game contents are distributed to consumers by both male and female group. Then, it extracted development factors for expansion of educational games and presented direction to educational game contents development by using educational games according to changes in users in order to secure mobile flat form contents for effective learning.

Recently, the rabid development of information technology has brought enormous changes in education. Consolidation of communications and multimedia technologies are enabling the new educational paradigm such as distance learning and virtual education. Furthermore, many studies in the education engineering field report that teaching using multimedia technologies more enhances students' performance than the traditional instructor-teaching method. However, little research regarding the education using multimedia has been done in the MIS filed. None of multimedia-related studies could be found in the top-ranked MIS journals published in Korea for the last five years, and only a few studies were found even worldwide. In this regard, the purpose of this study is to investigate which features of multimedia software are most important to enhance the teaching results of students. From the previous research, we found out the specific features of the educational multimedia software which are considered to affect the students'performance, and defined the research variables related to those educational software features. And, based on the constructivism and motivation theory of the education engineering field a theoretical research model and research hypotheses were developed. Perceived usefulness of the class and a student's perceived interests in the class were used as surrogate variables to measure teaching performance. Total 277 students participated separately in one of the two multimedia classes which have continued for three weeks. One was C programming language class and the other was multimedia CD-title development class. Each student listened for the multimedia session of the class using multimedia software and, at the end of the multimedia session, answered the survey questionnaire. The results of the study show that motivation to the class and the contents of education were statistically significant to the students'performance in the class. That implies, not only in the traditional instructor-teaching method but also in the multimedia class, that the contents of education itself and student's motivation to the class are most important to raise instructional results.

In this paper we proposed web-based educational multimedia contents development method using Web 3D technology and implemented web 3D contents for use at the education field. A implementation of contents is composed of modeling to specific entity in 3D shape, convert modeling data to enable data at web and include in webpage. A practical use of contents on this research can provide more advanced user experience and immersion.

Through the development of the Internet and multimedia systems, usage of cyber education with multimedia contents is increasing. On-line education differs from face-to-face education in that it overcomes the limits of the time and space, and supports a repeated self study at the student's study level while using several media and educational contents. In this paper, we will design and implement e-commerce educational content which is effective for students and useful for the process of cyber education. In addition, we will produce statistics from a questionnaire which questioned students on the effectiveness of the content.
