The decay of the Old Chinese Dynasty, Tang in the 10th century caused the collapse of the political order of Southeast Asia and the neighboring countries began to try to go their own way. Japan abolished the system called "Yudangsa" and nourished the culture of Japanese style. The fang age had a respect of the′Japanese Character Culture", in which when we expressed the sound, they developed the Japanese letters ,that is, reduced Chinese characters, and systematized them as linguistic symbols and developed them into one of letter design styles. The Japanese letters which was mainly the media of the expression of the female literature were delicately shaped ′as natural materials, which finally resulted in Japan′s oldest letter modeling, Asite Letter Design Style. The Japanese letters were blended with ′Reeds around the Lake", "Sea Birds", "Birds′flying", and "Rocks", mixed with the overall shapes of the objects and assimilated into one part, and became a means for the main entertainment of the nobility such as "Singing Festival", "Conference", and "Ceremonial Events" According to the relics, the Japanese feeling of a small cosmos was represented with the fabulous skills of artifacts. In audition, "Play Painting"in the countryside is also a kind of Asite the ordinary people accepted as wit and satire. What we will have to notice is about exchange of the Chinese letter designs, when the thought focused ′on the letter design, Jobcheso was popular. The letter design Jobcheso is -a kind of letter design which represents -natural objects and was popular at the time of Yukjo Dynasty, and there are some documents of that period left both in Japan and Korea. "Hyojedo" in Korea is supposed to have been influenced by the letter design. Asite- is also considered to have been "Japanese Letter Jobcheso." Therefore, the purpose of this study is to look into the origin of the letter designs in the Chinese character culture circle, in terms of the letter design of Jobcheso.

본 연구에서는 "통계학은 어렵다"라는 인식이 어느 정도인지를 알아보고 어렵게 느끼고 있는 이유를 찾는다. 이를 위하여 리서치회사에서 연구원으로 일하고 있는, 통계학을 배웠던 경험이 있는 사람들을 대상으로 설문조사하였다. 그 결과, 응답자 중 80.8%에 이르는 사람들이 "통계학은 어렵다"라고 인식하는 것으로 파악되었다. 그리고 어려운 이유가 대학에서 배운 통계학 교재가 어렵게 쓰여졌기 때문 (62.5%)이라는 것이다. 따라서 시중에 유통되는 통계학 교재들을 분석한 결과, 대부분의 교재들이 확률변수를 나타내는 대문자 X와 확률변수들이 취하는 값을 나타내는 소문자 x를 구분하지 않고 있다는 점을 밝혀내고, 이런 구분이 왜 통계학교육에 있어 간과되어서는 안 되는가를 지적하였다. 이 연구 결과가 향후 교재를 집필하거나 교육하는데 참고가 되어, 사회적으로 "통계학이 어렵기만 한 분야는 아니다"라는 인식이 확산되기를 바란다. 통계학을 폭넓게 보급하는 것은 통계학자들의 책임이기 때문이다. 이를 위하여 통계학교육에 대한 연구도 활발해지기를 기대한다.

한글의 기하학적 배조상의 복잡도로 부터 한글 각 자소의 character generator용 diode matrix의 size를 추산하고 이자소 matrix 3성(초성, 중성, 종성)의 OR동작으로시 모아쓰기 한글의 모든 조합이 가능합을 보였고 수평각음순가성과 수직모음용초성의 자판 선택자, 종성이 있을 때와 없을때의 중용길이의 변경등이 비교적 간단한 논리회로로서 switch될 수 있음을 보였다. 새로 15bit내부 code를 제안하였는데 이는 86개의 sparse diode matrix로시 모든 조합을 다 카버하고 그러면서도 decodig기구의 규모를 줄여준다. The required minimum size of character diode matrix of Korean letters is estimated from the topological complexity of letter structure. The OR aombination of three letter boards (diode matrice) gives all possible Hangout whole letters in proper traditional combined form with minimum required discernibility. Two forms of first consonants (centre located ones for horizontal vowels and leftward displaced ones for vertical and composed vowels) are switched by only 1 bit of the vowel code. The vowel pattern length is modified by again the last four bits of the code. A new 15bit sized inner code is proposed which permits considerably small sized decoding mechanism.

This letter proposes a tapered stacked microstrip antenna for application in small unmanned aerial vehicles (UAVs), which has advantages in mountainous terrains. With its tapered structure and increased bandwidth designed to operate at the resonance frequency of 2.4 GHz, the proposed antenna improves directivity, accuracy, and precision of small UAVs. The test flight results show the proposed tapered antenna has a three times higher impedance capability of 350 MHz based on VSWR<2. The transmission pattern is also more reliable than that of previous antenna designs.

컴퓨터나 스마트 폰에서 한글 입력을 위해 여러 한글 입력 시스템들이 존재한다. 그러나 기존 한글 입력 시스템은 입력된 글자를 수정하는데 많은 노력을 요구한다. 본 연구에서는 수정 대상글자를 재활용하여 효과적인 글자 수정을 수행 할 수 있는 방안을 제안한다. 본 연구에서 제안한 "자모 수정 창"을 활용한 한글 수정시스템은 한글 구성 체계의 특성을 최대한 반영하면서, 기 입력된 자음과 모음을 최대한 활용하는 수정 시스템이다. 또한 기존 한글 입력 시스템의 입력 체계에 추가적인 수정 없이, 오직 "자모 수정 창"만을 제공함으로써, 효과적인 글자 수정이 가능하다. 특히 협소한 한글 입력 체계를 갖는 스마트폰 환경에서 본 연구 결과가 더 유용하다.

Built-in redundancy analysis (BIRA) is widely used to enhance the yield of embedded memories. In this letter, a new BIRA method for both high repair efficiency and small hardware overhead is presented. The proposed method performs redundancy analysis operations using the spare mapping registers with a covered fault list. Experimental results demonstrate the superiority of the proposed method compared to previous works.

The objectives of this study are to analyze Korean speakers' pronunciations of various Japanese /p/ patterns and to provide desirable pronunciation models. This is a part of an ongoing research that aims to propose a useful method of teaching Japanese pronunciation of /p/ to Koreans. The experimental data consist of /p/ phonemes in word initial, word medial, and 'yoon' positions. Yoon must be written in small size after a letter and it only makes a syllable with the preceding letter in Japanese. There were 22 different phoneme positions. They were pronounced by 48 Japanese majoring students (24 females and 24 males), who were in their twenties and were raised in Daejeon and vicinity. The individual pronunciations were collected and digitized into 528 files. The results show that Koreans pronounced the Japanese phoneme /p/ in a variety of ways, according to the auditory environments in which the phoneme was tested: as [ph] in word initial, [pp] or [ph] in word medial, and [ph] in 'yoon', unlike native speakers who pronounced Japanese /p/ as [ph] in word initial, [pp] in word medial and, and [pp] or [ph] in 'yoon'.

Korean EFL learners' stylistic sensitivity was examined through the two types of letter writing, professional and personal. The base of comparison with the English native speakers' stylistic sensitivity was the linguistic style markers that were statistically found by Biber's (1988) multi-dimensional model of variation of English language. The main finding was that Korean university students were sensitive to stylistic difference in the correct direction, though their linguistic repertoire was limited to the easy and simple linguistic features. Also, the learners were skewed in the involved style in both types of the letters unlike the native speakers and it was interpreted as due to the general developmental direction from informal to formal linguistic style. Learners were also skewed in the explicit style in both types of letters unlike the native speakers and it was interpreted as due to the learners' heavy reliance on one particular linguistic feature. As a whole, the learners' stylistic sensitivity heavily relied on the small number of linguistic features that they have already acquired, which happen to be simple and basic linguistic features.
