SMIL을 이용하여 텍스트, 이미지, 음성, 영상, 애니메이션 등의 다양한 멀티미디어 클립들을 시간적/공간적으로 자유롭게 배치하고, 다양한 멀티미디어 프리젠테이션을 구성할 수 있는 교육용 컨텐츠를 구현할 수 있다. 하지만, SMIL은 HTML이나 XML과 같이 태그를 사용하므로 이를 구현하기 위해서는 텍스트 입력이 가능한 메모장이나 워드프로세서 등을 사용하여 문서를 작성해야하기 때문에 그에 따른 각각의 태그와 속성을 모두 암기해야만 효율적인 컨텐츠를 제작할 수 있다. 그러므로 사용자 입장에서는 시간적인 면에서, 또는 비용면에서 비효율적인 방식이다. 본 논문에서는 멀티미디어 동기화 언어인 SMIL을 기반으로 한 교육용 멀티미디어 컨텐츠 및 멀티미디어 데이터를 누구나 손쉽게 제작하고 처리할 수 있도록 SMIL을 기반으로 하는 교육용 컨텐츠 저작 시스템을 개발하여 컨텐츠를 제작하는 사용자들의 번거로움과 불편함을 없애고 효율성을 높일 수 있게 하였다.

As multimedia information recently increases fast, various types of retrieval of multimedia data are becoming issues of great importance. For the efficient multimedia data processing, semantics based retrieval techniques are required that can extract the meaning contents of multimedia data. Existing retrieval methods of multimedia data are annotation-based retrieval, feature-based retrieval and annotation and feature integration based retrieval. These systems take annotator a lot of efforts and time and we should perform complicated calculation for feature extraction. In addition. created data have shortcomings that we should go through static search that do not change. Also, user-friendly and semantic searching techniques are not supported. This paper proposes to develop S-MARS(Semantic Metadata-based Multimedia Annotation and Retrieval System) which can represent and extract multimedia data efficiently using MPEG-7. The system provides a graphical user interface for annotating, searching, and browsing multimedia data. It is implemented on the basis of the semantic metadata model to represent multimedia information. The semantic metadata about multimedia data is organized on the basis of multimedia description schema using XML schema that basically comply with the MPEG-7 standard. In conclusion. the proposed scheme can be easily implemented on any multimedia platforms supporting XML technology. It can be utilized to enable efficient semantic metadata sharing between systems, and it will contribute to improving the retrieval correctness and the user's satisfaction on embedding based multimedia retrieval algorithm method.

This paper proposes the design of user centric pavilion information guide system based on mobile device such as PDA. which is composed of system interface factors as user wants. The suggested information guide system is convenient for user carrying because it is based on PDA mobile device and the used liquid browser system makes all data information displayed on a small screen in contrast with the other browser system. Indeed, factors of system interface can be re-composed by user interaction. And this system can effectively provide the detail information about the exhibited objects as various media data such as text, image, voice, music, video etc. The proposed system is made up of media database server. mobile system control server and mobile system interface which accepts user interaction and displays the information. Each system is networked based on TCP/IP and uses XML (extensible Markup Language) and JAVA 2 micro edition to be able to update data. This feature enhances a wide use to be able to load this system on the any mobile device.

According to the development of information processing technology and computer hardware, PACS systems have been installed in many hospitals. They can increase the efficiency and the convenience remarkably for handling medical images using digitalized data. After we compare the generation images with other cases, we can read the images correctly and decide how to treat the patients. If the results, included test method and specialist's opinion, are represented dynamically on homepage in hospital. then visitors can get their experience in directly and understand the field of examination and the area of medical treatment. In this thesis, we display the effective images such as MR of the abnormal cases according to parts and diseases, the movie and still images such as Angio image, the other multimedia materials such as the sound and text of doctor's opinions, in SMIL based on XML, concerning the problem of concurrency.
