The school library plays an important role to improve the student's mental activity and cultivate the formation of character and emotion. Especially in the information society, the students must collect, select and utilize the necessary information themselves. The school library has to collect, put in order and keep the book, audiovisual material and necessary information beyond it about the entire education and to offer the students and teachers them for the general school education. The school library has to be a center of school education and drive forwards the spontaneous and subjective learning activity as well as progress the education process. The school library must be the place to preserve the student's subjective study ability, that is, consolidate the materials as the study center and be composed of proper study materials for the solving-problem and research. Also to be perfect in the role of the information center, the school library has to be consolidated in accordance with development of various information softwares and ways including the newspaper, magazine, video, CD, laser disk and computer. It is required for the information of school library to be corresponded actively to the multi-media society.

Electrical appliances such as audiovisual equipment and personal computers have recently had heat and electromagnetic problems. In order to solve those problems, 'High heat absorbing pre-painted steel sheet (hereinafter referred to as PSS)', 'High electromagnetic shielding PSS' and 'High heat absorbing and high electromagnetic shielding PSS' have been developed. In this paper, the heat characteristics and electromagnetic shielding properties of PSS are investigated by methods that use enclosures and their mechanisms are discussed. It was found that 'High heat absorbing PSS' and 'High heat absorbing and high electromagnetic shielding PSS'could reduce the heat problem. The mechanism of the heat characteristics was presumed for the high heat absorptivity of the back coating inside the enclosure. And it was also found that 'High electromagnetic shielding PSS' and 'High heat absorbing and high electromagnetic shielding PSS' could shield electromagnetic waves well. The mechanism of the electromagnetic shielding properties was considered for the low transfer impedance of the back coating inside the enclosure. 'High heat absorbing PSS' and 'High electromagnetic shielding PSS' have been adopted as materials for electrical appliances and 'High electromagnetic shielding and high heat absorbing PSS' have been tested for that purpose.

The MPEG-4 standard is aimed to define an object based audiovisual coding standard to address the emerging needs from interactive broadcasting. Since a broadcasting program is created on the basis of its objects, it is considered that MPEG-4 is most suitable for interactive broadcasting contents production and it can be retrieved in terms of its properties. But, there is no system that protects the copyright of digital contents and manages copyright and possibility that contents producer and author's copyright receives infringement at process that exchange contents mutually rose very. Therefore, we need to control and distribute contents according to user's permission rights. In this paper, we present the authoring system based on MPEG-4 IPMP for copyright and protection of MPEG-4 contents. The main features of the proposed approach is to provide an MPEG-4 compliant IPMP authoring system in a plug-in type along with standardized interfaces, which is to be able to incorporated into an existing MPEG-4 content authoring system. In this way, it is capable of authoring content to the MP4 file format while accommodating protection and management of content in a unified way. Furthermore, it also allows a user to edit and/or author IPMP information in a more efficient way by offering form based user interfaces.

In the age of information, newly produced knowledge is mostly written in English. Therefore, there has been a strong demand for English language learning in the EFL context. However, most EFL learners possess a lack of interest and motivation in the text-based reading class. In this educational context, film is one of the most widely used materials in English reading classes considering that modern learners are predominantly familiar with various audiovisual materials. The purpose of this study is to investigate how Korean EFL learners experienced in the film-based reading class. Specifically, this study aims to analyze the EFL students' perceptions about the class and learning strategies that they used during the class. In order to comprehensively interpret the EFL learners' experiences in the classroom, a coding system consisting of five categories was developed: report, emotion, reflection, evaluation, future plans. The results of data analysis showed that the use of movies in English reading classes had positive effects on reading comprehension and inference of word meaning. The most frequently used learning strategies were affective strategies which helped them control their emotion, attitude, motivations and values, whereas memorization strategies were rarely used. In this respect, this study suggests that the use of movies in the EFL reading classroom encourage students' attention and help them obtain and activate schema which is useful in gaining a better understanding of text-based reading materials.

MPEG-4 describes audiovisual scenes that are composed of several media objects, organized in a hierarchical fashion. And for end users, it brings higher levels of interaction with content, within the limits set by the author. These spatio-temporal arrangements of the objects in the scene are specified using a parametric methodology, BIFS(BInary Format for Scenes). This paper proposes MPEG-4 Contents Authoring System that provides visual configuration of an MPEG-4 scene and its event information. The developed MPEG-4 Contents Authoring System generates streaming MPEG-4 Contents, such as BIFS stream, OD(Object Descriptor) stream automatically.

In order to improve safety consciousness due to the increase in disasters and safety accidents, safety education is necessary to prepare for disasters with interest in safety. This study is a board game design for disaster safety education for elementary school students based on Keller's learning motivation theory. By considering the school safety curriculum and the safety education contents of the School Safety Mutual Aid Association and the Ministry of Public Administration and Security, the content and goals of learning were derived and the order of learning was determined. When designing game content, the fun elements of the game were applied to Keller's learning motivation inducing factors such as attention concentration (A), relevance (R), confidence (C), satisfaction (S), and educational game design elements to induce the achievement of learning goals at the game planning stage. It is expected that the existing safety education focusing on lecture-style and audiovisual will be supplemented and used in the educational field.

Desktop Documentary is a new documentary mode which uses a screen capture technology to complete the multitasking process of the creator who searches in the Internet Open Archive instead of shooting with a camera and remixes the selected multimedia contents using a computer interface. In this paper, we explore the desktop documentary that transforms potential archives into database narratives in the new media environment, converts cinematic mise-en-$sc{\grave{e}}ne$ into computational mise-en-interface, and transcends the boundaries between creation and criticism through creative mechanism as curation through stream of consciousness. We also examine the concept, type and characteristics of the desktop documentary which emerges since 2010s as an experimental attempt of new media art, a new hybrid genre of mainstream horror film, a new mode of fiction film, a new mockumentary style, and a new form of video essay and audiovisual critique.

The purpose of this study was to examine the effects of shoulder rehabilitation exercise convergence program. This study used a nonequivalent control group pretest-posttest design. A sample of 58 patients undergoing shoulder surgery, was included. The experimental group was given shoulder rehabilitation exercise convergence program including audiovisual education, shoulder rehabilitation exercise and exercise monitoring. The data were collected using a structured questionnaire and measured range of motion(ROM) of shoulder joint and were analyzed using descriptive statistics, ${\chi}^2-test$, t-test and ANCOVA. The experimental group reported significantly lower shoulder pain than control group(p<.001). Shoulder joint ROM and exercise self-efficacy were significantly higher in the experimental group than in the control group(p=.038; p<.001). This findings indicate that shoulder rehabilitation exercise convergence program can be an effective intervention for shoulder surgery patients. Continued development of convergence interventions for patients undergoing various conditions in practice, is suggested.

비디오 프레임 내의 오버레이 텍스트는 음성과 시각적 내용에 부가적인 정보를 제공한다. 특히, 뉴스 비디오에서 이 텍스트는 비디오 영상 내용을 압축적이고 직접적인 설명을 한다. 그러므로 뉴스 비디오 색인 시스템을 만드는데 있어서 가장 신뢰할 수 있는 실마리이다. 텔레비전 뉴스 프로그램의 색인 시스템을 만들기 위해서는 텍스트를 검출하고 인식하는 것이 중요하다. 이 논문은 뉴스 비디오에서 오버레이 텍스트를 검출하고 인식하는데 도움이 되는 오버레이 텍스트 시작 프레임 식별을 제안한다. 비디오 시퀀스의 모든 프레임이 오버레이 텍스트를 포함하는 것이 아니기 때문에, 모든 프레임에서 오버레이 텍스트의 추출은 불필요하고 시간 낭비다. 그러므로 오버레이 텍스트를 포함하고 있는 프레임에만 초점을 맞춤으로써 오버레이 텍스트 검출의 정확도를 개선할 수 있다. 텍스트 시작 프레임 식별 방법에 대한 비교 실험을 뉴스 비디오에 대해서 실시하고, 적절한 처리 방법을 제안한다.

This study analyzed the characteristics of Physical Environment of existing free shuttle bus Interior centered on elderly people who frequently use free shuttle buses. The purpose of this study is to provide basic data that can be used for improvement of existing free shuttle buses. In the case of the old type, in terms of accessible design, the middle entrance is not normally opened except the wheelchair occupant, so that the entrance of the front wheel is always used. Therefore, most elderly people go to the back seat and travel distance is twice longer. In addition, many stairs caused frequent inconveniences for boarding. In the case of the new type, it is planned to be a low-floor type, and various types of safety rods and handles, pictograms for enhancing the information convenience are well-equipped, and the measured value of the overall design characteristic is high. However, in the case of mental stability, it was confirmed that the seat of the bus is colored with a cold color system and is in a different relationship with the warm color which can feel mental stability. Overall, both old and new shuttle buses lack audiovisual feedback on bus routes and route guidance in terms of Supportive design. Also, since the cleaning tools and other miscellaneous items were left in the room, it became an obstacle to space utilization in terms of adaptable design. In terms of safety, both shuttle buses did not come into view with fire extinguishers shaded by miscellaneous items. Therefore, immediate action is unlikely in case of emergency. This problem should be resolved quickly.
