This study was practiced in order to develop a textbook to improve early childhood teachers' ability to use multimedia required by kindergartens and to examine its effects. First, investigation of the status of multimedia application of early childhood teachers in kindergartens was done along with looking through their attitude and anxiety. The expertise and the multimedia education was required in early childhood education and curriculum. As a result, 15 categories and 50 subcategories under 4 themes were drawn through the procedures of qualitative analysis. The conclusions obtained through this study were the following: First, the education for multimedia application related to the tasks required in kindergartens is needed instead of the common education for multimedia application, to improve the ability to use multimedia for early childhood teachers. Second, multimedia education based on visual theory for the purpose of early childhood education, rather than common features-centered multimedia education, is helpful for the improvement of early childhood teachers' ability to use multimedia. Finally, the improvement of early childhood teachers' ability to use multimedia will be a chance to provide children with a better educational environment.

Mobile electronic display applications represent a simple motion and express personal motions recently. In this context, we propose the Mobile Signage Application as against these existing applications. It provides the quality motions by multiplex editing and thus should share a kinetic typography with other people using Bluetooth. The Mobile Signage Application includes kinetic motions that are developed by HTML5 and JavaScript to attain variety effects. Furthermore, usability evaluation shows its sufficient availability and serviceability.

Nowadays application of modem achievements of information technologies in science, engineering and education is usual phenomenon. Application of these technologies allows easily creating new methods of learning of mathematics. More of new methods of creation of multimedia electronic manuals on high mathematics are founded to application of multimedia and communication opportunities of the computer. But application only multimedia and communication opportunities of the computer at creation of multimedia electronic manuals on high mathematics is insufficient to elimination of 'gap' between training and studying high mathematics. So, we offer a new way of the decision of this problem: creation of a multimedia electronic manual on high mathematics with built-in a mathematical environment MathCad in the national language.

Wavelet transform (WT) has attracted most engineers and scientists because of its excellent properties. The coherence of practical approach and a theoretical basis not only solves currently important problems, but also gives the potential of formulating and solving completely new problems. It has been show that multi-resolution analysis of Wavelet transforms is good solution in speech analysis and threshold of wavelet coefficients has near optimal noise reduction property for many classes of signals. This paper proposed applications of wavelet in speech processing: pitch detection, voice-unvoice (V -UV) decision, denoising with the detailed algorithms and results.

MPEG-21 is an on-progress project of the Moving Picture Expert Group (MPEG) that has been started in many independent parts such as part for standardizing the declaration of a digital item (MPEG-21 Part 2: Digital Item Declaration), right expression language (MPEG-21 Part S: Rights Expression Language), way to process the digital item (MPEG-21 Part 10: Digital Item Processing), etc. All this part is intended to form a framework to enable transparent and augmented use of multimedia resources across a wide range of networks and devices (1). In this paper, we show our research initiative to develop a web-based application that utilized many parts of MPEG-21 technology. The implemented concept uses a digital item and license providers in the server side while the MPEG-21 Conformant application is implemented as a plug-in application that will be downloaded to the user terminal when user accesses the webpage for the frist time. The result of this research shows that with some combination of MPEG-21 parts, we can develop an authorized multimedia delivery and consumption application.

Recently MPEG (Moving Picture Experts Group) has started a new standardization activity called MPEG Multimedia Middleware (M3W). The M3W supports multimedia applications Independent of hardware and software such as operating systems so that the portability and interoperability of multimedia applications are greatly improved. In doing so, the M3W adopts the concept of a service-based middleware. The M3W standardizes a set of multimedia Application Programming Interfaces (APIs) and their implementations can be pro vided by third parties In the form of services. In this paper, we introduce the usage of XML metadata in describing the standard multimedia APIs and third party's services and also we explain the role of the XML Schema within the M3W in providing transparent access from application to the M3W services.

Multimedia interpretation describes a high level of ion of multimedia content like interrelations and coherencies. In this paper, we describe a multimedia interpretation component from human-centered perspective. In this context, we see the role of the multimedia interpretation component as a liaison between the psychological apparatuses and computer-based artifact. We emphasize this role of multimedia interpretation by outlining a mapping process of the psychological apparatuses and computer-based artifact. This mapping process needs to be transparent to its user so that effective human-centered systems can be achieved. This transparency will provide an immersive environment for the users and enable uninhibited interaction between the users and the artifact. Furthermore, we illustrate how the multimedia interpretation component can be utilized in the medical diagnosis and treatment support application.

기존의 셋탑박스는 단순히 디지털 방송물 수신하는 기능에 머물렀다. 그러나 지금은 PVR, 데이터 방송을 지원하는 인터렉티브 어플리케이션, 홈네트워킹 하에서 컨텐츠를 다양하게 처리하는 복합적인 멀티미디어 어플리케이션 등이 탑재된 다기능화된 제품들이 출시되고 있다. 본 시스템은 아날로그 TV와 디지털 TV의 기능을 하나로 합친 유럽향 멀티미디어 셋탑박스를 개발하기 위해 함께 구현되어진 Multimedia Contents Application의 구현에 대해 서술하고 있다. 메모리 스틱을 이용하여 데이터 전달을 수행하는 File Explorer와 함께 멀티미디어 기능을 수행하는 Photo 시bum, Media Player, Juke Box 등을 함께 구현하였다. 오디오, 비디오, 이미지를 디코딩 하기 위한 갖가지 코덱들을 자체적으로 개발하여 최적화시켰다. 또한 좀더 사용자가 친숙한 UI를 위하여 다양한 테스트를 거쳐 사용자 편의적인 UI를 구현하였다.
