Multimedia contents' searching methods in existing mobile computer environment tend to be brought with many over heads when attempting to search data in large bulks. The MINT system has been studied to resolve such problem. However, MINT system delivers many over heads by searching multimedia contents through applying B-Tree. The suggested method is said to be CST-MCR searching system based on CST-Tree. The specific characteristic of this method is improved MINT system by applying CST-Tree's index. The result of capacity evaluation came out with improved capacity of 4.27% from MINT system and CST-MCR methods in average. Conclusively, it has been proven that the suggested method is superior.

New media is an emerging industry sector. It sits at the nexus of what has become a main vehicle of the Knowledge Based Economy. the crossroads where the use of interactive multimedia technology meets the traditional uses of media. The current Education information Act provided school with PC, multimedia labs and connection to internet. Having such a facility in schools encourage teachers and students to use computers more often. Teachers demand for more educational multimedia contents than they can find in the market. Although there are many good contents, teachers find them unfit or inflexible for their curriculum. The purpose of this study is to identify the elements of standard multimedia studio facilities to develop multimedia contents in primary and secondary schools. The result of this study will provide guidelines for schools to facilitate their multimedia studio for teaching and learning activities, and developing contents for effective use of their facilities.

Misunderstanding of multimedia in the computer industry, the confusion of consumers, and the lack of understanding of technology in the human context provide an impetus for examining and speculating on the future of multimedia. "What can a multimedia technology do ?" is not a sufficient question for consumers until we add "for whom." Both how the relevant technology is likely to develop and how human choices would be made are examined with a focus on historical trend in media technology adoption.

With the development of digital technology and the influence of the global pandemic, the metaverse, a three-dimensional virtual world, is receiving attention in society, economy and overall industry, and the manufacturing industry is also accepting it as a major strategic agenda for digital transformation. Therefore, in this study, the concept of the industry metaverse from the perspective of the manufacturing industry was defined, and the types of the industry metaverse were classified into four types by reflecting the characteristics of the manufacturing industry based on the general metaverse scenario presented in previous studies. These are Virtual behavior simulation, Augmented operation of business objects and Virtual experience simulation, Augmented decision of business subjects. In addition, through case analysis of solutions used in the manufacturing industry, it was confirmed that the central technology of the Industry Metaverse is the digital twin, and that it is being implemented by convergence with major digital technologies such as virtual reality, augmented reality, digital human, and AI. This study will be able to provide guidelines for future research on the metaverse from the perspective of the manufacturing industry and establishment of a digital transformation strategy for the industry.

This paper has done a study of Chinese-Korean cooperative multimedia design education. Sino-Korean school of multimedia was set up by Shanghai University of Engineering Science (SUES) and Korea Dongseo University in October 2002. We have created "3.5+0.5 Teaching Model". In this model, Chinese and Korea professors take courses together. Firstly, paper points our the Chinese government policy background of Chinese-Foreign Cooperation in running schools and the development of Chinese-Korean cooperative multimedia design education in SUES. Secondly, by analyzing the multimedia design industry to understand the Chinese multi-media design education. Thirdly, paper made in-depth studies for "3.5+0.5 Teaching Model" so as to draw the experience of successes and problems. Through analysis of "Questionnaires for students' learning and living conditions in Dongseo University in 2009" by spss 16.0, paper made a research of mode of "A semester studying in Korea". Finally, paper points out the development direction of Chinese-Korean cooperative multimedia design.

온라인게임 산업은 많은 성장과 발전을 이루어 왔다. 게임업체들의 고통 중의 하나로 온라인의 특성에 따라 짧아지는 게임제작 파이프라인과, 빠른 제작 스케줄에 적합하며 쉽게 게임 제작 시 응용 적용이 가능한 다양한 3D게임캐릭터 애니메이션의 형태별, 동작별, 종류별로 분류된 애니메이션 모델 기준연구를 필요로 하고 있다. 본 연구에서는 실 사례 중심으로 게임에 이용된 디지털 기반 게임 캐릭터의 요소별 모델 분류 설정을 연구 분석하여 3D게임캐릭터 애니메이션 제작에 필요한 기초자료를 도출 한 후 디지털 모션캡처시스템을 활용하여 실시간으로 다양한 캐릭터 애니메이션의 실사 움직임 제어연구를 진행하여 게임산업 및 디지털 콘텐츠 산업에 효율성이 높고 짧은 시간에 적용 가능한 캐릭터애니메이션 제작 과정 및 제작 파이프라인 도출해보고자 한다.

최근에 인터넷상에서 정보이용이 급증함에 따라 멀티미디어 정보를 효율적으로 관리하고 검색하기 위한 여러 가지 방법들이 제안되고 있다. 따라서 본 논문에서는 SRR(Semantic Reference Relation)과 DRR(Direct Reference Relation)을 이용한 새로운 그룹화 방법을 제안한다. 제안된 방법은 MDI(Multimedia Document Informations)를 멀티미디어 객체 클러스터로 간주하여 그룹화 한다. 제안된 방법의 성능을 알아보기 위하여 1000개의 멀티미디어 문서데이터를 테스트하며, 그 결과 제안된 방법의 성능이 보다 효율적임을 보인다.

With widespread use of the Internet and improvements in streaming media and compression technology, digital music, video, and image can be distributed instantaneously across the Internet to end-users. However, most conventional Digital Right Management are often not secure and fast enough to process the vast amount of data generated by the multimedia applications to meet the real-time constraints. In this paper, we propose the copyright protection using encryption of DCT coefficients and motion vector in MPEG-4 video codec of mobile device. This paper presents a new Digital Rights Management that modifies the Motion Vector of Macroblock for mobile device. Experimental results indicate that the proposed DRM can not only achieve very low cost of the encryption but also enable separable authentication to individual mobile devices such as Portable Multimedia Player and Personal Digital Assistants. The performance of the proposed methods have low complexity and low increase of bit rate in overhead.
