The subjects of this study were 86 eight- and 76 ten-year-old children(total: 162). Experimental procedures and tools included pre- and post- learning tests and controls for intelligence (Draw-a-Man-Test) and for cognitive styles(Children's Embedded Figures Test). The content of the learning task was the lightning generation process. After various types of seven-minute color animation multimedia presentations about the generation of lightning were screened, post-hoc analysis showed that the rehearsal strategy was effective with field-dependent learners but not with field-independent learners.

This research results can be used in games or animation application programs that need special effects and can be used as education software in undergraduate or graduate courses. If we use this results effectively in application programs, we can expect no small ripple effect on growing entertainment industry because special effects enhance audience's interest in games, films, and amusements.

As rapid development of new hardware control interface technology, new concepts have been being proposed and emerged. In this paper, a new approach based on leap motion system is proposed. While we employ a position information from sensor, the hand gesture recognition is suggested with the pre-defined patterns. To do this, we design a recognition algorithm with hand gesture and finger patterns. We apply the proposed scheme to 3-dimensional avatar controling and editing software tool for making animation in the cyber space as a representative application. This proposed algorithm can be used to control computer systems in medical treatment, game, education and other various areas.

국내 전력소비량은 1961년 전원 개발을 본격적으로 추진한 이래 세계12위 규모로 성장하였다. 그러나 전력사용 증가에 따른 전기화재, 감전 및 설비사고 등 전기재해 역시 계속 증가하여 전체 화재사고 중 전기로 인한 화재비율이 선진국과 비교하여 크게 높은 실정이다. 본 연구에서는 전기안전에 관한 국민의식 제고를 목표로 전기안전 교육을 위한 애니메이션(3D 및 2D 프로그램)을 제작하여 전기 안전문화를 조성하는 홍보매체로 활용할 수 있도록 연구를 수행하였다.

This study explored the characteristics of contemporary furniture called New Design furniture design in terms of aesthetics of communication in the postmodern era. Qualitative conceptural analysis as the principal methodology was used to explore the characteristics of New Design furniture, which is accessible to the broadest possible public. Thereby, the communicative elements of symbol, metaphor, narrative, animation, imagination, humor, and/or wit expressed in New Design furniture were analyzed according to the designers'concept and work. As a result the postmodern aesthetics of communication made New Design furniture accessible to the largest number of People through cultural considerations in New Design furniture as it influences designers 'concept and work. However, it showed problems of New Design furniture in connection with postmodern aesthetics affecting mass production. Therefore, the designers have begun rethinking, redefining, and redesigning their furniture aesthetically, functionally, economically, and ecologically.

Nowadays, smart phone is being popularly used for communication, entertainment, and information retrieval. While demands on video traffic over mobile networks increases sharply, the wireless link capacity is often limited to fully support the traffic demand. Therefore, the size of video data needs to be reduced to provide high quality video with limited capacity. To handle this issue, we propose a video editing system using the ffmpeg library. The proposed system can provide a high quality video with a relatively small data size, thereby facilitating the mobile streaming services and live-video games.

The digital signal has been replaced the analog signal in most of every field of multimedia including still image, animation, and audio due to the enormous extension of computer supply and the fast development of computer network. The consumers of information are able to enjoy the abundance of information because of one of the digital signal traits that very easy to regenerate the original data. Because of the trait, however, it is very hard for the producers of information to keep the copyright with the merit of original copy in quality excellency. In this paper, the watermarking technology which inserts a RGB color watermark in color image using the visual characteristics of wavelet coefficient was proposed. As a result, the PSNR value of image was varied depending on perceptual parameter, but we can obtain 32dB as a whole.

In order to efficiently provide the learning ability for engineering education, electromagnetic field simulator have been developed on lava 2 platform. Each simulation module based on lava applet can be easily utilized with independent platform and provide GUI environment to set up physical conditions. The numerical results using computer animation technique are provided in real time. To aggregate and manage the learning objects, application of SCORM which is e-Learning standards is also studied.

This paper studies a collision detection technique to dealing with moving polyhedra. Even though the problem is well-studied in computer graphics, the existing methods are inapplicable to highly dynamic environments. We use the GJK algorithm to determine collisions between convex objects. Also, our method is applied for moving objects.
