Liquid crystal-polymer composite(LCPC) films promising new materials for both projection displays and vision product. LCPC films consist of a continous liquid crystal phase embedded in a three- dimensional network of polymer matrix. The liquid crystal in these LC phases can be elecrtrically switched giving rise to an opaque scattering off-stats and a transparent, non-scatting on- stats. In this work. a premixture is composed of LC, UV-curable monomer and photonitiator. LCPC films are formed by photopolymerization induced phase separation from this premixture. In conclusion, structure and electro-optical properties of LCPC films strongly depends on the selection of monomer, LC content and curing rate.

The purpose of this study is to examine whether the Jinsim-Jikseol was written by Ji-Nul or not. The book with were known so far have been thought in that they had a Susimgyul and were attaced Gecho-Simhak-Inmun. But we now know that the edlited state of known were not the reflection of those times but the result of artificially editing by peple later. The contents of Jinsim-Jikseol are differed from that of others in understanding of the system of Sam-Mun and Cheyoungwan. The results based on this study is that the possibility which Jinsim-Jikseol is not work of Ji-Nul is quitely high. And it will be help to understand the ideas of Ji-Nul more systematically and articulately.

As the animation prevails through the public recently, animation fields editing and creating greatly have attention and get into the spotlight. Nevertheless, such solutions in LINUX environment tend to be worse than those in Windows. In this paper, we propose Motion Space Prime in LINUX, which is capable of creating stop motion animation easily such as clay animation. Users can interactively edit motions captured by a digital camcorder.

The cyber-education is fully recognized and proliferated such as to Internet language centers or virtual universities, and so on. However, the acquisition of e-learning tools as well as the construction of educational contents are quite difficult tasks. Therefore, in this study, important information for the acquisition of hardwares such as multimedia editing tools, servers, educational facilities is suggested, and the critical success factors for the acquisition of cyber educational solution softwares such as authoring tools and loaming management systems are proposed.

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.

기존 웹상에서의 수학식 처리 및 표기에 관련된 문제점을 보완하고, 수학식의 효율적인 표기 및 저장, 공유를 가능하게 하기 위해 W3C(World Wide Web Consortium)에서는 XML(extensible Markup Language) 애플리케이션인 MathML(Mathematical Markup Language)을 제정하였다. 본 논문에서는 MathML 문서를 보다 쉽고 효율적으로 편집할 수 있도록 사용자 중심의 다양한 인터페이스 제공을 통해, MathML 지식이 없는 사용자라도 쉽게 편집이 가능하도록 하였으며, 내부적으로는 처리속도 향상을 위해 기존 XML 파서의 기능 다수를 설계 및 구현하였다. 본 편집 시스템은 웹상에서의 MathML 사용의 보편화에 기여하고, XML을 기반으로 하고 수학식을 포함하는 문서의 효율적인 처리 등에 유용하게 사용될 것이다.

3D 모션 데이터를 생성하는 것은 어려운 작업이다. 보다 효율적으로 3D 모션 데이터를 생성하기 위해 키프레임 방식, 모션편집, 모션편집 등 여러 가지 방법이 적용되고 있다. 가장 최근에 많이 적용하고 있는 모션편집 방식은 모션편집에 있어 여러 가지 장점을 가지고 있다. 모션편집 방법이 다른 방법보다는 3D 모션 데이터 생성이 쉬운 편이지만 그래도 많은 노력과 시간을 요구한다. 그러므로 적은 시간과 노력을 들이고 보다 효율적인 3D 모션데이터 생성을 위해 다양한 방법이 시도되고 있다. 본 논문에서는 모션편집 작업 중에 발생하는 모션 불연속문제를 효율적으로 해결하기 위하여, 곡선 보간법(Curve Interpolation)과 블랜딩(Blending)함수를 활용하여 모션의 연결부분을 자연스럽게 연결하는 기법을 제시하고자 한다.

In this paper, we developed an Android application named VIVID where users can edit the moving captions easily on smartphone videos. This makes it convenient to set the time range, text, location and motion of caption text on the video. The editing result is uploaded to web server in html and can be shared with other users.

In the study for effective speech control we designed a personal computer system with A/D converter in which the speech signal is transformed by digital data displayed graphically on the moniter and with a D/A converter in which the digital data is transformed into speech signal which people can hear. We analyzed the character of the speech signal produced by the system. We designed the adaptive noise cancel algorithm so that noise and Interference are cancelled whenever the speech signal is recognized by the computer system. This is a basic system for artificial Intelligence.
