The purpose of this paper is to gather pairs of heteronyms in Modem Korean and to propose that all of them should be differentiated in both the Hanngul orthography and Romanization as well as in the IPA transcription. More than a quarter of the whole Korean vocabulary consists of words with a long vowel and the number of minimal pairs distinguished only by the chroneme reaches nearly ten thousand (ie. twenty thousand words). It is suggested here that the letter s in Hanngul and the letter 'h' in the Roman alphabet be used to represent the long vowel. Another factor which brings forth lots of heteronyms in Korean is the lacking of enough indication as to non-automatic reinforcement in the initial consonant o( a word (or a morpheme) when following another within a phrase (or a word). It is proposed here that the non-automatincally rienforced word-initial consonant should be written with the letter h (like ㅺ, ㅼ, ㅽ, ㅾ) and an apostrophe (like 물'새 or 밭'이랑, 물'약) in Hanngul, and with the letter c and an apostrophe (like c'g-, c'd-, c'b-, c'j- ) in the Roman alphabet The morpheme-initial reinforced consonant within a word is written with the letters k, 1, p and cz for ㅺ, ㅼ, ㅽ, and ㅾ respectively. The contrasted pronunciations of pairs of heteronyms beginning with ㅁ/m sound are transcribed here for exemplification in the IPA, Roman alphabet and Hanngul.

PURPOSE: People with physical disabilities such as cerebral palsy usually experience obstacles when interacting with computer through conventional keyboard because of their motor disabilities. The purpose of this study is empirically compare of text entry(alphabet and word) speed and accuracy using the three different keyboard type on four students(male 2 and female 2) with cerebral palsy. METHODS: This research design used a replicated single-case experimental approach to compare the individual performance. An alternating treatments design was used to examine the effectiveness of standard QWERTY keyboard and alternative keyboard(mini and big keyboard) on computer access for students with cerebral palsy. To avoid changes in posture that influence a keyboard character entry training and evaluation was carried out using his sitting in a wheelchair. Compass software program used in this study as an assessment tool to measure speed and accuracy when performance of text entry(alphabet and word). This was repeated until the stable status of reaction time. RESULTS: As a result, the alternative keyboard seems to be the most effective device for students with cerebral palsy to perform text entry. But various factors such as peculiarity of motor disabilities, experience and preferences of the user are heavily related. CONCLUSION: Thus, we must perform the objective and systematic assessment for computer access and if sustained training is accomplished, it could to improve speed and accuracy of text entry(alphabet and word).

In this paper, a performance comparison between two blind signal estimation algorithms in a LTI channel is considered. The two algorithms, Iterative Least-Squares with Projection (ILSP) and a modified ILSP, are based on the finite-alphabet property of input symbols. This case typically arises in a multiple access system with a sensor array antenna at the receiving end. We start with the formulation of a maximum-likelihood (ML) estimation problem under an additive white Gaussian noise assumption. A blind ML estimator is derived with its iterative algorithm for calculation. Then we narrow down the consideration of this problem to QPSK case so that a modified algorithm is proposed for $\pi$/4-QPSK case. The modified version is compared with the original ILSP algorithm in terms of the rate of the convergence to global minima. A computer simulation shows that the modified algorithm gives a better performance. This result implies that the performance of the blind separation algorithms may be greatly improved by adopting a smart coding scheme with rich structure.

Accidents or disease can lead to acquired voice dysphonia. In this case, we propose a new input interface based on eye movements to facilitate communication for patients. Unlike the existing method that presents the English alphabet as it is, we reorganized the layout of the alphabet to support the Korean alphabet and designed it so that patients can enter words by themselves using only eye movements, gaze, and blinking. The proposed interface not only reduces fatigue by minimizing eye movements, but also allows for easy and quick input through an intuitive arrangement. For natural communication, we also implemented a system that allows patients who are unable to speak to communicate with their own voice. The system works by tracking eye movements to record what the patient is trying to say, then using Glow-TTS and Multi-band MelGAN to reconstruct their own voice using the learned voice to output sound.

1967년에 국내최초로 컴퓨터가 도입된 이후 국가경제의 발전과 함께 컴퓨 터시스템의 수는 급격히 증가하였고 4대의 대형 multiprogramming시스템을 포함 하여 50여대의 컴퓨터가 운용되고 있다. 그러나 해외에서 도입된 컴퓨터는 영문 을 중심으로 개발되어 있어 한글 데이터의 코오드화 및 입출력시스템의 개발, 한 글분류(sorting) 및 한글 compiler의 개발 등 한글화하여야 할 문제점이 많다. 한 글의 특성을 formal grammar theory를 중심으로 고찰하고 이를 기계화하기 위한 입출력장치의 개발을 위한 문제점을 검토하였다.

Computer based instruction in the elementary science curriculum will be played an important role through the fifth curriculum reform from the 1989 school year. This is essential for the science instruction because the strategies on the problem-solvings and inquiry approaches can be utilized for the science classroom. Computer education can be thought as the education about the computer and the education using the computer. Of them the education using the computer means the computer assisted instruction(CAI) what is called all the possible activities using the computer in the classroom. Student achievement as the result of CAI depends on the learning activities of students and the instructional techniques and strategies of teachers using the computer. However, computer based education to enhance the student achievement is pointed out the lacks of the standardized Korean alphabet code and the compatibility of qualified software. These problems will be relieved according to the coding for the Korean alphabet of SUPER PILOT program language.
