개인용 미디어 단말로서 MP3 플레이어는 이제 음악 파일을 감상하기 위한 일상 생활에서 중요한 휴대 필수품이 되었으며 단순히 음악을 재생하는데 그치지 않고, 각종 정보들을 표시하기 위한 작은 화면이 부착되고 있으며 더 나아가 이미지 정보나 동영상을 표현할 수 있는 기능들이 추가 되고 있다. 이처럼 변화하는 멀티미디어 서비스에 발맞추어 MPEG 에서는 Multimedia Application Format (MAF) (ISO/IEC 23000) 라는 새로운 표준안을 제안하였다. MAF 표준안의 기본 방식은 산업 현장 및 사용자의 요구에 빠르게 부응하기 위해, 기존에 존재하는 표준안들을 결합시켜 새로운 멀티미디어 파일 포맷을 정립하였다. 그 첫 번째 결과물로서, 이미 널리 쓰이고 있는 MP3 파일 포맷에 새로운 기능을 추가하기 위한 Music Player MAF 포맷의 FDIS 가 제안되었다. Music Player MAF 는 MPEG-1 Audio Layer III(MP3) 와 MPEG-7 MDS 메타데이터 정보를 결합한 파일 포맷으로. 기존 ID3 태그에서 표현되는 정보 보다 훨씬 풍부한 메타데이터 정보와 더불어 선택적으로 하나의 JPEG 이미지를 포함한 형태로 이루어져 있다. 그러나, 현재의 파일 포맷은 시간이 고려되지 않은 하나의 JPEG 이미지만을 포함할 수 있기 때문에, 오늘날 사용자가 요구하는 다양한 멀티미디어 서비스를 제공하기에는 많은 한계점을 갖고 있다. 본 논문에서는 Music Player MAF FDIS 에 제안된 세가지 형태의 Music Player MAF 파일 포맷에 관해 기술 한다. 복수의 JPEG 이미지 및 텍스트를 저장하기 위하여 각각의 파일 포맷이 갖는 문제점을 언급하고 하나 이상의 JPEG 이미지와 자막 정보를 MP3 음악 정보와 동기화 시켜 추가 할 수 있는 기능을 추가를 제안한다. 또한 제안된 파일 포맷을 쉽게 생성할 수 있도록 기존의 XMT-O 스키마를 기반으로 MAF 를 위하여 새롭게 MAF XMT 스키마를 정의하고 정의된 스키마를 기반으로 구현된 Music Player MAF 의 저작툴과 제안된 확장 뮤직 플래이어 MAF 을 위한 재생툴을 구현한다.

Kinect sensor version 2 is a kind of camera released by Microsoft as a computer vision and a natural user interface for game consoles like Xbox one. It allows acquiring color images, depth images, audio input and skeletal data with a high frame rate. In this paper, using depth image, we present a surveillance system of a certain area within Kinect's field of view. With computer vision library(Emgu CV), if an object is detected in the target area, it is tracked and kinect camera takes RGB image to send it in database server. Therefore, a mobile application on android platform was developed in order to notify the user that Kinect has sensed strange motion in the target region and display the RGB image of the scene. User gets the notification in real-time to react in the best way in the case of valuable things in monitored area or other cases related to a reserved zone.

This paper proposes an effective tempo feature extraction method for music information retrieval. The tempo information is modeled by the narrow-band temporal modulation components, which are decomposed into a modulation spectrum via joint frequency analysis. In implementation, the tempo feature is directly extracted from the modified discrete cosine transform coefficients, which is the output of partial MP3(MPEG 1 Layer 3) decoder. Then, different features are extracted from the amplitudes of modulation spectrum and applied to different music information retrieval tasks. The logarithmic scale modulation frequency coefficients are employed in automatic music emotion classification and music genre classification. The classification precision in both systems is improved significantly. The bit vectors derived from adaptive modulation spectrum is used in audio fingerprinting task That is proved to be able to achieve high robustness in this application. The experimental results in these tasks validate the effectiveness of the proposed tempo feature.

This paper proposes how to support various media on online conversational activity using XML(extensible Markup Language). The method converts media information into XML based messages and handles alike conventional text based messages. The XML based messages are unified to an XML document, and then a HTML document is generated using the XML and an XSLT documents in a server. A user in each client can play or present media through the hyperlink that is associated media information on the HTML document. The suggested method supports use of various media (text, image, audio, video, documents, etc) and efficient maintenance of font size, color, and style on messages according to extension and modification of XML tags. For application, this paper implemented the system to support media that has client and server architecture on online conversational activity. A user in each client inputs text or media based message using JAVA applet and servlet on the system, and conversational messages on every users' interfaces are automatically updated whenever a user inputs new message. Media on conversational messages are played or presented according to a user's click on hyperlink. Applications for the media presentation are as follows : distance learning, online game, collaboration, etc.

The purpose of this study is to search the effective teaching-learning program by considering how affect on formation of linear function using Excel. This study was based on qualitative case study. The teaching experiment using Excel executed with five 8th graders' students for second research content. Teaching experiment was performed for two classes. Collecting the data was conducted via observations and interviews with students. The data include audio and video recording of the students' work, students' worksheets and detailed field notes. The conclusions drawn from teaching experiment are as follows: First, when students explored relevancy content of function in Excel environment, formation of concept of function was facilitated by experiencing operation of algebraic formulas, tables and graphs. We could infer that formation of concept was effected by conjecture activity and iterative process of feedback through Excel environment. Second, the students explored the changes very interestingly making algebraic formulas and presenting tables and graphs. The students were familiarized with observation on algebraic formulas, graphs and tables concurrently. Also, they tried to look for general rules through inductive observation. According to this study, we noticed that exploration teaming environment using Excel could supplement paper-and-pencil environment.

The Moderns are contacted with various Media in many ways. Korea is the arena of competition in many kind of Media as a powerful country in the Information and communication. Then we can realize advanced in the quality of contents and technology. There are getting various kind of audio-visual teaching method. Then how do the puppet shows approach with what viewpoint? You may find them in the education for the Kids and the Handicapped. You will understand that will be able to attend with a role of a Educational medium as(a method of)medical treatment. On the point of view, I am about to study how to shape into the puppet shows as a traditional medium. And what will be expected much more influenced when accepts principles of Esthetics of an Image? I expect to purify emotion by Puppet shows to the Moderns who are live in the rapidly changing period situation. I would like to observe about making process of Puppet-show with application of the image language.
