This study identifies the key determinants and technology innovation adoption type of participation in multimedia UCC services. This research examines how the major factors of perceived usability, self-expression, fun & entertainment, arousal, information sharing, other's positive reputation and interface easiness contribute to participation in multimedia UCC services. A sample survey of internet users was conducted, responses were collected from 629 respondents and consumer streaming data were analyzed. Some of the practical implications of the results are follows. This research have categorized that the types of technology adoption for the participation of UCC were innovator consumer, early adaptor consumer, early majority consumer, and late majority consumer. The results of multiple regression analysis indicated that perceived usability, interface easiness, fun & entertainment, self-expression, arousal, other's positive reputation and type of technology adoption posited a significant effect in multimedia UCC Services.

The production and authoring of digital multimedia contents are most important fields in multimedia technology. Nowadays web-based technology and related multimedia software technology are growing in the IT industry and these technologies are evolving most rapidly in our life. The technology of digital audio and video processing is utilizing rapidly to improve quality of our life, Also we are more interested in high sense and artistic feeling in the music and entertainment areas by use of three dimensional (3D) digital sound technology continuously as well as 3D digital video technology. The service field of digital audio contents is increasing rapidly through the Internet. And the society of Internet users wants the audio contents service with better quality. Recently Internet users are not satisfying the sound quality with 2 channels stereo but seeking the high quality of sound with 5,] channels such as 3D audio of the movie films. But it might be needed proper hardware equipments for the service of 3D sound to satisfy this demand. In this paper, we expand the simple 3D audio generator developed and propose a web-based music bank by the software development of 3D audio generation player in 3D sound environment with two speakers minimizing hardware equipments, Also we believe that this study would contribute greatly to digital 3D sound service of high quality for music and entertainment mania.

Now a days many industries and bigger organisation (Indian Railways, Bharat Heavy Electricals Ltd.) are facing difficulties in implementing the new technology because of non-availability of fully trained staff. Also for the employed technical and other staff lot of resistance management has to face to get them trained for adoption of new technology. There are also very less organisations who can design effective training programmes and at the same time develop course material specially multimedia packages and computer base training (CBT) which can satisfy the need of different target groups of industries. Indian Railways was also facing similar situation while implementing the Air Brake System technology In Indian Railways. TTTI Bhopal took that challenge and designed, developed and trained Indian Railways trainer for implementation of the package on different target group. The present paper offers a case study on the same.

Vehicle communication networks have some deficient network resources to support a vast multimedia service including safety driving information, video, news and some broadcast relayed from the playgrounds such as professional baseball games for autonomous vehicles. This paper deals with the framework for providing seamless multimedia service including safety driving information using multicast in cooperated-connected vehicle communication network (CVCN). It adopts smart-switch (SS) and smart intelligent multicast agent(SIMA) to support the seamless multimedia service. The SS manages and switches multimedia streams through SIMA in CVCN network. The SIMA to operate as an access point, is composed of multicast supporting part and control part of mobile devices/autonomous vehicles in CVCN network. Therefore this proposed technique using SS and SIMA within CVCN network is a new framework for multimedia service that can disperse the load of server.

최근 멀티미디어 기술과 네트워크의 발전으로 멀티미디어 콘텐츠의 생성은 빠르게 늘어가고 있다. 그러나 이를 찾고 활용하는 기술은 부족하다. 이러한 문제를 보완하고 해결하기 위해 멀티미디어 콘텐츠를 위한 표준안들이 많이 있으나 멀티미디어 데이터 형식과 상호운용성을 표현하기에는 부족하다. 본 논문에서는 멀티미디어 콘텐츠를 상호 운용할 수 있도록 하는 온톨로지 기반의 콘텐츠 검색 시스템을 제시한다. 온톨로지는 MPEG-7의 MDS(Multimedia Description Scheme)와 같은 스키마 구조에 온톨로지 구축을 위한 규칙을 제시하여 구성한다. 이러한 온톨로지를 바탕으로 멀티미디어 데이터가 가지고 있는 연관성을 확장하여 의미론적 검색 시스템을 구축한다.

The recent development of information technology in general and consolidation of communications and multimedia technology in particular have brought enormous changes in education and training methods in many business organizations. Numerous studies in the education engineering field report that teaching using multimedia technologies will more enhance the education/training performance than the traditional instructor-teaching method. However, in the management information systems field, few studies are found which directly investigated effects of multimedia technologies on education and training. None of multimedia-related studies can be found in the top-ranked MIS journals published in Korea for the last five years, and only a few stuides are found even worldwide. The major steps of the current research are as follows. First, in order to identify important factors constituting the effectiveness of multimedia systems, previous research related to the effectiveness of multimedia systems was reviewed and analyzed. Second, individual items which can be considered as candidates to represent the effectiveness of multimedia systems were derived from this previous research review, and a survey questionnaire was developed using those derived items. Based on the developed survey questionnaire, a pretest was administered at several domestic business firms with experiences of multimedia systems. Third, survey questionnaires were distributed to and collected from the 517 employees which experienced using multimedia systems.
