This study analyzed the main bodies, sizes of litters, spaces between letters, Words, lines, length of lines, sizes of main body and margin, Position of the main bodies of PDF(Portable Document Format) in high schools and "the criteria of reading system for the textbooks" which was suggested by the Department of Education and Provided some suggestions for the improvement. First, it is judged that spaces of the main body of textbooks should be shrunken to make the ratio of 50:50 between the main body and space margin. Second, it is judged that the main body should be placed in the center of text page. Third, the results of the above findings showed that it would be difficult to deal with the task of deciding space and position or the main body and marginal space in a form of single project, because there are many variables involved and psychologically complicated elements which can not be measured objectively.

In this paper, we present the design strategy of the assistive communication system to be able to communicate or the mute and speech disorder under the restricted circumstances. To be used conveniently in daily life, first, a specific domain should be set according to circumstance, and second, proper words in each domain should be selected according to physical, mental ability of user. As the design process of this system should be reflected by the abilities of user, each word is represented as symbols, transparently. The sentences are compounded from symbols. Compounded sentences are showed on display in letters, and synthesized naturally in voice in order to be understood easy.

This paper presents a method for constructing and using transliteration rules which are based on Phonics, an instructional method for speaking and writing English letters. Conventional approaches to automatic transliteration often focused on statistical methods. However, the construction or the collection of correct transliteration examples is always the bottleneck of the statistical transliteration model. Also, in practical domains where the collection of such data is very difficult, such as education and tourism, it is reasonable to build a system without much qualified data. Furthermore, compared with Korean orthography of borrowed foreign words, the proposed approach is much easier to construct, and can generate more refined rules. The experimentation result shows that the proposed approach can improve the performance of a statistical-based transliteration system.

This study explored the linkage between literacy and writing with a computer in three-to five-year-old children. The 57 subjects were closely observed as they produced written language forms using the word processing program, Araeha Hangul. Stages of writing with a computer were developed to assess the children's computer-writing. While writing with a computer, children invented letters, words, and sentences in an experimental and playful way. Children's writing with computer improved with age. There was a positive correlation between writing with a computer and writing with a pencil. In this way, computer writing was found to be part of written language development.

To evaluate the postmortem changes in activities of oxygen free radical metabolizing enzymes, the rats were sacrificed with cervical dislocation and were kept in an incubator at $25^{\circ}C$, 70% of humidity for 12 hours. The activities of aniline hydroxylase, catalase, glutathione-S-transferase and superoxlde dismutase were decreased with the time. On the other hand, the activity and type conversion ratio (type D ${\to}$type O) of hepatic xanthine oxidase (XO) were gradually increased. From these changes of XO, the estimation of death time (mathematical equation) could be determined with the least square method. To clarify the cause of increasing XO activity, enzyme kinetics were examined. The Km values of XO were decreased with the time. In conclusion, the determination of liver XO activity might be used for the estimation of death time in the early postmortem period.

본 연구에서는 기계 가독형 사전 정보를 이용하여 중의어 의미 태깅을 위한 학습에 사용될 양질의 의미부착 데이터를 자동 생성하여 중의어 태깅 정확도를 향상시키는 방법을 제안한다. 또한 중의어의 의미별로 특징있는 주변 단어를 원소로 갖는 의미그룹을 생성하고, 의미그룹내 중요 자질의 가중치 선정에 집중도 개념을 도입하여 태깅 정확도를 높인다. SENSEVAL-2 데이터를 사용하여 태깅 정확도를 평가한 결과 본 연구에서 제안한 방법이 기존의 방법보다 정확도를 향상시킨 것으로 나타났다.

In this study, I've suggested how to improve the function of web-agents to find out the web-document users prefer. Web-agents employ TFIDF, which considers all the worked used in a document as equal in improtance to find out users' preferences. Web-documents like HTML, however, make visual differences by using different sizes of letters and highlighting them based on importance of words. In this study, I've attempted to improve the functions of the web-agents by differentiating the weight of each worked in accordance with the visual importance of each paragraph. To enhance functions, I've suggested how to make a profile from each paragraph to be consolidated later. As to suggested algorithms, I've tested their effects by comparing the established TFIDF algorithm with the function which helps users find documents they prefer.

In the previous research, we proposed a Kinetic typography font engine that can easily add motion to text with function call only. However, since it is aimed at constructing movements for a sentence, there is still inconvenience in the production of various kinetic typography motions in word or letter unit. We propose Kinetic Typical Extended Motion API(Application Programming Interface) that extends Kinetic Motion API. The extended Kinetic Typographic Font Engine aims to simplify the process of making kinetic typography in words and letters, including the kinetic typographic motion library provided as a function. In addition, various applications that can apply Kinetic typography A kinetic typography authoring interface is provided for facilitating the construction of a motion library for the robot.

역화일을 파일구조로 이용하는 정보 검색 시스템에서는 검색자가 검색할 분야의 완전 단어를 알고 있어야 검색이 가능하다. 그러나 검색자가 완전 단어가 아닌 단어의 부분 문자열을 알고 있는 경우가 많다. 이럴 경우 부분 문자열을 포함하는 색인어들을 검색할 수 있다면 관련 문서들을 검색할 수 있다. 또한 검색된 문헌 수가 너무 적을 경우 부분 문자열을 포함하는 단어를 색인어로 가지는 모든 문서들을 검색하기 위한 방법이 필요하다. 이런 요건들을 충족시키기 위해서는 사용자는 용어 절단 방법을 이용하여 질의어를 구성할 수 있어야 하고, 검색 시스템은 절단 검색을 지원할 수 있는 전자 사전이 필요하다. 본 논문에서는 절단검색을 효율적으로 지원할 수 있는 전자 사전 구조를 설계하고 구현한다. 이 전자 사전은 저장된 단어 수에 관계없이 주어진 한 개의 단어 검색 시간 및 역 문자열로 구성된 단어 검색 시간이 빠르고 일정하다. 절단검색을 효율적으로 지원하기 위하여 트라이 구조를 이용하였으며, 빠른 검색 시간을 지원하기 위해 배열을 이용한 방법을 사용하였다. 절단된 용어의 검색 과정에서 확장할 문자열의 길이를 최소화하여 검색 시간을 줄였다.

In this paper, a korean text to sign language translation system is designed and implemented for the hearing impaired people to learn letters and to have a conversation with normal people. We adopt the direct method for machine translation which uses morphological analysis and the dictionary search. And we define the necessary sign language dictionaries. Based on this processes, the system translate korean sentences to sign language moving picture. The proposed dictionaries are composed of the basic sign language dictionary, the compound sing language dictionary, and the resemble sign language dictionary. The basic sign language dictionary includes basic symbols and moving pictures of korean sign language. The compound sing language dictionary is composed of key-words of basic sign language. In addition, we offered the similar letters at the resemble sign language dictionary. The moving pictures of searched sign symbols are displayed on a screen in GIF formats by continuous motion of sign symbols or represented by the finger spelling based on the korean code analysis. The proposed system can provide quick sign language search and complement the lack of sign languages in the translation process by using the various sign language dictionaries which are characterized as korean sign language. In addition, to represent the sign language using GIF makes it possible to save the storage space of the sign language. In addition, to represent the sign language using GIF makes it possible to save storage space of the sign language dictionary.
