In recent years, China Digital Media Design related undergraduate education has developed into great dimensions while producing a lot of problems. Now cause of rapid development, Disciplinary Location, Training Objectives and Curriculum require study. Firstly, the paper points out the scope and general process of Digital Media Design through an analysis of properties of digital media industry. Secondly, the paper studies the current status of Digital Media Design-related undergraduate education from the policy of Chinese Ministry of Education and the practice of representative universities. Through questionnaire survey of Digital Media Designers from Beijing, Shanghai and Guangzhou, the paper points out the problems of China Digital Media Design related undergraduate education. Finally, paper brings forward the right direction of new system of China Digital Media Design related undergraduate education.

The wide spread of the Internet and personal computers does not only alter the form of content from analog to digital, but also lead to the emergence of a new digital media system that is different from analog media system. The digital media system is a convergent media that includes both public and private systems from the perspective of use-limitation, as well as storage and enjoyment systems from the perspective of use-purpose. The major goal of this research is to suggest and empirically verify an effective way of presenting the perception of places that are converged in the digital media system. Involvement and motivation are suggested as key conceptual factors and color contrast and hue are suggested as concrete design factors to make people perceive corresponding places. Results of our controlled experiment indicated that the color contrast and hue significantly affected the perception of place, and consequently, influenced usability of the digital media system. This paper ends with implications that can be used to construct appropriate perception of places for the media system of digital products.

시스템을 입력과 출력간의 함수관계로 볼 때 출력에 대한 상대차수가 정의되지 않는 점을 특이점이라고 정의할 수 있다. 본 논문에서는 적절한 기하학적 조건을 만족하는 해석적인 시스템(analytic system)에 대하여 그러한 특이점의 성질을 살펴본다. 특이점을 지나는 궤적은 특이점의 특이도와 그에 관련된 함수 값의 부호에 의해서 특이점의 주변에서는 특이 매니폴드를 기준으로 한 영역에서 나머지 다른 영역으로 통과하거나 혹은 그를 기준으로 어느 한 쪽의 영역에만 머물러 있게 됨을 보임으로써 특이점과 이를 지나는 궤적의 상관관계를 명확히 규명하였다.

최근에 광 디스크 기기의 고배속화에 따라서 디스크의 재생 속도는 점차로 증가하고 있다. 이러한 경향에 따라 트랙킹 제어 루프에서 나타나는 디스크의 편심에 의한 외란의 영향은 더욱 커지게 되므로 기존의 선형 제어기만으로는 디스크의 편심량이 큰 경우에 고배속에서 원하는 트랙 추종 성능을 얻을 수가 없다. 본 논문에서는 이러한 문제점을 해결하기 위해서 반복 학습 제어 알고리즘과 드라이브 시스템의 액츄에이터의 주파수 응답 특성을 이용한 새로운 트랙 추종 제어 방법을 제안한다. 또한, 제안된 트랙 추종 제어 시스템의 제어 성능을 실험을 통하여 검증하여 본다.

Our Digital Carousel enables user to share media objects through media synchronization mechanism. We implemented the Digital Carousel so that the users participated in collaborative work may refer shared media or error objects as the same view to others. This paper explains the design and implementation of the EC_DXS(Error Control in Digital Carousel System). EC_DCS is a system that is suitable for detecting sharing and recovering software error based on multimedia CSCW(Computer Supportes Cooperated Work). With error sharing system, a group cooperating users can share me. applications. From the perspective of multimedia collaborative environment, an error application becomes another interactive presentation error is shared with participant engaged in a cooperative work.

The purpose of this paper is to analyze and compare the existing digital media asset management systems and develop a prospective implementation model. As a result of conducting this research, it is recommended that the prospective system consists of an archiving server, a processing server, and an interface system. This result suggests important starting point to develop a resonable and reliable implementation model for digital media asset management system.

The purpose of this study is to suggest the design by using digital media the general hospital. The important result and advantage of the study are as follows; At first, applicability and maintenance of form and function design are enhanced and the digital media could be used for development of better and economical design. Secondly, the 3D CAD system useful for communication media and instructional tool for hospital planners and designers. Thirdly, fast and economical evaluation are obtained through the study of experimental simulation. Finally as a new tool in architectural field, the system helps to enhance the relationship between digital media and human. New concept and tools of hospital design are being developed in terms of its function, environment, and psychology. The computational design system should be improved for user friendly in the future.

High-quality digital broadcasting contents are susceptible to illegal copy and unauthorized redistribution, which makes broadcasters difficult to protect valuable media assets. So, broadcasters and content providers need the technology for copyright protection of professional digital content. Digital watermarking technology is one of the most actively developed solutions for the copyright protection. This paper suggests the requirements of watermarking technology in DTV(Digital TV) environment for copyright protection and shows the developed real-time watermark embedding/detecting system for HD(High Definition)/SD(Standard Definition) video and experimental results of the system against watermark attack tests. Our watermarking system meets the watermarking requirements of invisibility, robustness and security of DTV environment.
