본 논문에서는 아동 교육시 활용할 실감형 교육 콘텐츠(Realistic Educational Content)를 구축하여 수업활동시 활용했을 때의 학습향상 효과를 살펴 본 결과 시각 청각을 이용한 콘텐츠보다, 후각을 추가하여 수업을 진행하였을 때 학생들의 집중과 수업에 대한 몰입감이 높아진 것을 실험결과 알 수 있었다.

대량의 컨텐츠에 대한 정보 관리 및 잦은 사이트 변화에 따른 퍼블리케이션의 용이성으로 CMS(Contents Management System)의 도입이 많이 이루어지고 있다. 본 논문에서는 CMS의 백앤드와 프론트 엔드를 연결하는 Access Structure 에 관해 고찰해보고, 이를 통해 시스템의 컨텐츠 검색을 효율적으로 지원할 수 있는 방안과 카테고리 수의 무분별한 증가를 막고자 하며, 퍼블리케이션에서의 확장된 아키텍쳐를 지원하기 위한 모델을 제안하고자 한다.

To meet the high demand of the experts in the multimedia industry, many colleges opened the subject related to multimedia technology and pre-learning has been rapidly increasing among the students. However, most instructor is still appling the traditional teaching model rather than the one customized for the pre-learner of multimedia. This paper is to reveal the pre-learner's strong desire in detail and suggest the characteristics of the teaching model and teaching materials. We applied the new paradigm, constructivism and problem-based learning, which rising in the educational literature to suggest and design the lecture model to bring up the experts in the multimedia industry.

The requirement of distributed multimedia applications is the need for sophisticated QoS(quality of service) management. In terms of distributed multimedia systems, the most important catagories for quality of service are a timeless, volume, and reliability In this paper, we discuss a method for increasing reliability through fault tolerance. We describe the design and implementation of the ECA running on distributed multimedia environment. ECA is a system is able to classify automatically a software error based on distributed multimedia. This papaer explains a performance analysis of an error classification system running on distributed multimedia environment using the rule-based DEVS modeling and simulation techniques. In DEVS, a system has a time base, inputs, states, outputs, and functions.

The purpose of the study was to develope e-Learning multimedia resource management system to support developing of e-Learning contents. This system is to create and manage multimedia resources like video, audio, and image more easily. We analyzed and redesigned media asset management system that would be used in broadcast, press, and industry. This system has SCORM metadata and is consisted of Windows 2003 server and RDBMS. The survey was conducted to investigate usability and satisfaction for the developed system.

In this paper, for maintaining the presentation quality of multimedia contents, we define the several events that can happen in showing when handle the multimedia contents. Also we classified these events in 4 types based on each characteristic. Furthermore we design the event model which can manage synchronization of presentation by control and managing the events. Also we propose an idea that maintain the quality of presentation service by interaction between each module and threads related in progress of show. Especially, in this research, we focus the active process for the user's participant and the unpredictable state variation of IMPSs(Interacitve Multimedia Presentation Systems).

The contents for multimedia are very activated along to revolution of Internet. So this fact allows the contents for multimedia to be commercialized. These contents , however, included much vulnerability that it is difficult to be commercialized because attackers easily reproduce that. Many developers want to use watermarking method as the technique to protect the contents for multimedia, but it is very vulnerable to use only one method. This paper proposes the Secure DRM system which protects the contents for multimedia using Public Key Infrastructure and steganography methods. The SDRM system is more powerful than general DRM systems in that it has the special feature of watermarking and steganography techniques. We can prevent the attackers from reproducing and stealing the contents illegally, and authenticating users through SDRM systems.

According to the advancement of display devices, the multi-screen contents display environment is growing to be accepted for the display exhibition area. The objectives of this research are to find communications technology and to design an editor interface of contents delivery system for the larger and adaptive multi-display workspaces. The proposed system can find existence of display devices and get information without any additional tools like marker, and can recognize device layout with only web-cam and image processing technology. The multi-display contents delivery system is composed of devices with three roles; display device, editor device, and fixed server. The editor device which has the role of main control uses UPnP technology to find existence and receive information of display devices. extract appointed color in captured picture using a tracking library to recognize the physical layout of display devices. After the device information and physical layout of display devices are connected, the content delivery system allows the display contents to be sent to the corresponding display devices through WebSocket technology. Also the experimental results show the possibility of our device connection and layout recognition techniques can be utilized for the large spaced and adaptive multi-display applications.
