Recently, LEDs are used in various fields such as lightings, billboards, displays, and so on. In this paper, we tried to combine a costume with LEDs in a performance environment. To meet the environmental requirements, we propose a digital costume platform which consists of wireless network, an embedded system, a control jacket, a digital skin, and a pattern authoring tool. It is utilized for making a digital costume with LED lighting effects. The embedded system controls LED lighting according to the signals from a show control system through wireless networks. The control jacket can carry the embedded system and connect it with LEDs. The digital skin means a costume with LEDs. The LEDs were designed to fit in performance concept in point of aesthetic. The pattern authoring tool enables users to make timeline-based changing patterns of LED lighting. The proposed platform is a new lighting element in performances. It can expand stage representation techniques and be used as a special effect. It will play a role as a moving light in performances. We evaluated stable operations of our platform by employing it in live performances.

With the development of information and communications technologies, there have been increasing cases of services and use free educational materials in educational field through the Web. However, as most of the materials are provided in a finished form via the Web services, teachers are in a situation where they have difficulty in using the materials through development or revision according to their educational goals. In this background, this study aimed to develop requirements and functions necessary for the educational contents development tools by having teachers as actual users develop contents using existing tools of the educational contents development. As a result, this study developed 10 requirements, including intuitive interface environment, support for various multimedia materials, and diversification of output versions etc. Also, the study suggested 13 functions, including links with external resources, automatic format conversion function, usage and editing of existing documents, writing learner's answers, and hiding function etc.

Computers can intensify the students' motivation and understanding about the solution to the problems in class, therefore, computers can be the most appropriate educational tools for the study of problem solving and have been also recognized as a representable study method in the information age, which can pass on various educational experience to the right place at the right time. Mutimedia producing tool helps us develop and maintain the educational courseware by way of using general technology of multimedia system. In this thesis, it presents the efficient development process of educational software by using mutimedia producing tool, its educational advantages and problems, and its future progress direction as well.

The purpose of this study is to develop FVU, which enables teachers effectively to construct self-page on the screen, to reduce the size of file for teaching, and to correct many different kinds of event which was already made in the previous. The instrument used in the development of this Editor is UML(Unified Modeling Language), which is object-oriented methodology. The Authoring tool developed in this study is named FVU. The first page which is needed in class can be constructed by using VUEditor in FVU. Using VUEditor can get Instructional Syllabus exported into VUAuthor through Vector-transformation. Through this procedure, the size of image file comes to be reduced into forming low band width, which results in solving the problem of network traffic. Also, Instructor can create image, shape and text, and delete and correct errors or mistakes which make in the course of constructing materials for teaching. In conclusion, this VUEditor enables program designer to construct the first page, even without using such applied program as Image Tool and Power Point. This VUEditor makes instructor to make some contents for teaching easily.

Recently the technological advance in the hardware dealing with multimedia data as well as the explosive increase of the volume of multimedia data bring about new interest in the use of multimedia presentations in many application domains. To use multimedia presentations efficiently, the integration of multimedia presentations into DBMS is necessary. This paper presents a multimedia presentatation query language based on contents and query processing techniques. Presently, multimedia presentation authoring tools denote a multimedia presentation using a presentation graph which is a DAG. A Node in the graph is a same type of media stream and edges denote a play-out order and a synchronization way among nodes. The contents of presentations graphs are the information of each stream, the sequential order of the information inside each stream and the play-out order among the streams. GCalculus/S is a calculus-based query language and can deal with the contents of a presentation graph and physical characteristics of multimedia data. It expresses the sequential order of information inside each stream and the play-out order of streams of a presentation graph using temporal operators Next, Connected and Until. O-Algebra, which is object algebra, is extended to process GCalculus/S queries.

In this paper, we introduce an adaptive e-Learning system for engineering mathematics which is based on computer algebra system (Mathematica) and on-line authoring environment. The system provides an assessment tool for individual diagnosis using Bayesian inference network. Using this system, an instructor can easily develop mathematical web contents via web interface. Examples of such content development are illustrated in the area of linear algebra, differential equation and discrete mathematics. The diagnostic module traces a student's knowledge level based on statistical inference using the conditional probability and Bayesian updating algorithm via Netica. As part of formative evaluation, we brought this system into real university settings and analyzed students' feedback using survey.

As the animation prevails through the public recently, animation fields editing and creating greatly have attention and get into the spotlight. Nevertheless, such solutions in LINUX environment tend to be worse than those in Windows. In this paper, we propose Motion Space Prime in LINUX, which is capable of creating stop motion animation easily such as clay animation. Users can interactively edit motions captured by a digital camcorder.

정보기술과 디지털 기술의 발전에 힘입어 디지털 콘텐츠에 대한 수요가 증가하였다. 디지털 콘텐츠 중 비디오 콘텐츠는 순차적인 특성을 가지며, 시간과 공간정보가 결합된 3차원 데이타로써 처리시간이 높은 작업이기 때문에 검색이나 브라우징이 대단히 어렵다. 이러한 문제의 해결을 위하여 비디오 데이타를 구조화하는 동영상 내용 편집 도구(Authoring Tool for Video Contents)를 제안했었다. 본 논문에서는 동영상 내용 편집 도구의 연구를 확장하여, 이러한 구조화된 데이타를 이용하여 원하는 부분을 쉽게 볼 수 있을 뿐만 아니라, 검색을 위한 주석의 내용까지 보여줌으로써 사용자에게 효율적으로 제공할 수 있는 브라우징을 제안한다. 메타데이타가 저장된 XML파일을 이용하여 플렉스 솔루션으로 구현하였다. 즉, 웹 어플리케이션에 플래시를 도입시킨 것으로 플래시 플레이어(Flash Player)가 동작한다면 운영체제, 브라우저, 디바이스에 대해 독립적으로 실행될 수 있으며, 인터넷 익스플로어, 파이어 폭스, PDA, 핸드폰, 위성 단말기 등 어디에서든지 인터넷으로 같은 어플리케이션을 공유할 수 있는 환경을 제공할 수 있다.
