The purpose of this study was to investigate the status of nutrition education at elementary schools. A total of 226 elementary school teachers within Changwon and Milyang city participated in this study . The results of this study are as follows. The average score on a test of nutrition knowledge was 4.40 out of 10, and teachers of Milyang districts type scored significantly higher on nutrition knowledge than teacher of Changwon rural and Milyang rural districts. Only 9.0% of the teachers had nutrition education training. 64.1% of th total had teaching experience in nutrition, 91.0% of that was being taught as a part of physical education and home economics. The information source for nutrition education was mainly guide books and magazine and newspaper articles. Current nutrition education was being taught mainly by lecture(85.0%) but the preferred methods of teaching in nutrition education were small group discussion(44.3%), role-playing(22.9%) and lecture(21.4%). Audio visuals aids were used by 45.5% of the teachers and the most common of them were VTR(43.1%) chart(22.4%) as preferred audio visuals aids of them were VTR(71.9%) adn actual model(14.1%)

시청각 관련 지표 개발은 3차원 시청각 환경 제시기술, 시청각 감성을 활용한 Audio의 개발과 시청각 감성 측정기술 및 DB개발 등에 대하여 진행되었다. 3차원 시청각 환경 제시기술 개발은 VR 환경 제시 기술 개발과 모의 시뮬레이터를 통한 평가 단계 및 인간의 공간 인식 특성에 관한 연구로 이루어져 있다. 따라서 지표화 과정에서 VR 제시 시스템 관련 지표(3개), VR평가 지표(3개), 그리고 정보물(2개) 등 총 8개의 지표가 완성되었다. 시청각 감성을 활용한 Audio 개발과 시청각 감성 측정기술 및 DB개발에서는 시청각 감성에 대하여 주관적 평가 실시 후, 이를 이용한 제품개발 및 DB화하는 과정으로 구성되었으며, 각각의 연구물에 대하여 각각 6개와 13개의 지표가 완성되었다. 시청각 감성을 활용한 Audio 개발과 시청각 감성 측정기술 및 DB개발은 감성측정방법에서 제시 자극과 실험육법에서의 다소의 차이는 있었으나, 감성어휘 도출을 통한 SD척도법, 생체신호 측정, 자료처리방법 및 평가기준 등에서 유사성이 있었다. 따라서 각각의 연구물에 대한 지표 개발뿐만 아니라 지표간의 관련성을 비교ㆍ분석함으로써 체계화된 지표 표준화 과정이 필요한 것으로 보인다.

The Digital Audio-Visual Council(DAVIC) that was established to develop useful multimedia communication services has completed the specifications for providing on-demand services such as Movie on Demand(MoD), Teleshopping and accepting Internet service. And then they are proceeding the works to suport converstional communcation services like Plain Old Telecphone Service(POTS), Video telephone, Video teleconferencing. In this paper, we prpose an efficient terminal architecture which can provide conversational multimedia communication services on DAVIC Set-Top Box (STB) environments. To apply the implemented conversational terminal to the multipoint communication environment, we considered the factors of Qurlity of Services(QoS) that determine grade of conversational communication service. We also present the inter-working scheme and that system structure to satisfy QoS by using new MPEG video bridge which gurantees end to end delay requirements as major element of QoS for achieving the real time communication and does not accompany visual quality degradation.

Due to speech recognition problems in noisy environment, Audio Visual Speech Recognition (AVSR) system, which combines speech information and visual information, has been proposed since the mid-1990s,. and lip reading have played significant role in the AVSR System. This study aims to enhance recognition rate of utterance word using only lip shape detection for efficient AVSR system. After preprocessing for lip region detection, Convolution Neural Network (CNN) techniques are applied for utterance period detection and lip shape feature vector extraction, and Hidden Markov Models (HMMs) are then used for the recognition. As a result, the utterance period detection results show 91% of success rates, which are higher performance than general threshold methods. In the lip reading recognition, while user-dependent experiment records 88.5%, user-independent experiment shows 80.2% of recognition rates, which are improved results compared to the previous studies.

In this paper, a new interactive TV service model is proposed. The MPEG-4 system is specified for composing and managing various object streams including user interactions. The data broadcasting model supporting user interactions is designed using MPEG-4 system in our proposal. We evaluate possibility of proposed service model using simulation player. This player supports MPEG-2 TS which contains MPEG-2 video and AC-3 audio streams as a main service and MPEC-4 system data as interactive services as well as user specific EPG information, and XML data, etc as supplemetary services. The player also supports a multi-channel environment. The synchronization between audio and visual data is achieved by DTS and PTS in TS.

Most of digital media contents are composed with video and audio, picture and animation informations. Sometime, there is some deviation of information recognition quality for the video and audio information according to information receiver's characteristics or the understanding. But visual information using the text provide most clear and accurate ways for information recognition to human being. In this paper, we propose a new broadcasting system(BSDMC) to transmit clear and accurate meaning of the digital media contents. We implement general-purpose components to display the video, picture, text and symbol simultaneously. Only plug-in and call these components with proper parameters on the application developing tool, we can easily develop the multimedia contents broadcasting system. These components are implemented based on the object-oriented framework and modular structure so that increase the reusability and can be develop other applications quick and reliable.

Portable devices are growth such as smart phone and smart pad and e-book market is also growing, but existing publishers have some problem of conversion paper book to e-book with technology. In this paper propose to solve this problem using HTML5 for E-book making tool. HTML5 is new version of HTML. It can be use video and audio element. Also a lot of web Browser can be use HTML5 format. If we have HTML5 compatible browser devices, we can use anywhere and anytime. We propose video book making tool using these HTML5 characteristics, it is available to support of text or images.

This article takes the talk show "Beast Town" as an example to introduce the overall technical solution, technical difficulties and countermeasures for the combination of cartoon virtual characters and virtual studio technology, providing reference and experience for the multi-scenario application of digital humans. Compared with the live broadcast that combines reality and reality, we have further upgraded our virtual production technology and digital human-driven technology, adopted industry-leading real-time virtual production technology and monocular camera driving technology, and launched a virtual cartoon character talk show - "Beast Town" to achieve real Perfectly combined with virtuality, it further enhances program immersion and audio-visual experience, and expands infinite boundaries for virtual manufacturing. In the talk show, motion capture shooting technology is used for final picture synthesis. The virtual scene needs to present dynamic effects, and at the same time realize the driving of the digital human and the movement with the push, pull and pan of the overall picture. This puts forward very high requirements for multi-party data synchronization, real-time driving of digital people, and synthetic picture rendering. We focus on issues such as virtual and real data docking and monocular camera motion capture effects. We combine camera outward tracking, multi-scene picture perspective, multi-machine rendering and other solutions to effectively solve picture linkage and rendering quality problems in a deeply immersive space environment. , presenting users with visual effects of linkage between digital people and live guests.
