주어진 문법이 LL 언어를 생성하는가의 문제를 LL 변환 가능성의 관점에서 조사한다. LL 변환 가능 문법을 특징짓기 위해 기존의 방법은 비결정적인(nondeterministic) 복잡한 파서의 생성을 필요로 한다. 이에 기존 방법으로는 LL 언어의 본질에 대한 직관적인 이해가 어렵다. 이 단점을 극복하고자 본 논문에선 파서의 생성 없이 문법 자체의 분석을 통한 문법 유도(derivation)에 근거한 특징화를 제시한다. 새로운 특징화는 LL 언어의 본질에 대한 직관적인 이해를 도울 수 있다.

The study aimed to materialize the meaning of the names through analyzing names that have synonyms and ambiguous words. The subjects of the study are seven foreign language study books such as $\ll$譯語類解 Yeokeoyuhae $\gg$ $\ll$譯語類解補編 Yeokeoyuhae - supplementary book$\gg$, $\ll$同文類解 Dongmunyuhae$\ggl$, $\ll$象語類解 Mongeoyuhae$\gg$, $\ll$象語類解補編 Mongeoyuhae- supplementary book$\gg$, $\ll$俊語類解 Oaeeoyuhae$\gg$ and $\ll$方름類釋 Bangeonyuseok$\gg$. The study selected vocabularies related with headgear, socks, clothing from those vocabulary books. The results are as follows: 1. The result focusing on the same Chinese terms in multiple forms has shown that '帽子(Moja), 斗逢(Dubong), 頭面(Dumyen), 襪(Mal), 木?(Mokgeuk), 　據子(Nanmalja), 樓子(Oja), 小樓子(Sooja), 養衣(Saui), 團領(Danlyeng), 掛子(Goija), 齊肩掛(Jegyengae), 彩兒(Sama), 單補(Dango)' have differences in Korean annotations, and it has been found that these differences are spelt as synonyms in general. 2. The result focusing on the same Korean terms in multiple forms has shown that Gamto, Gat, Satgat, Bolkki, Gatmo, Neoneol, Gatdongot, Ddambatgijeoksam, Nuyeok, Tyeollik, Goui, Baji, Gatdongot, Hatot, Dongdoljji, Yusam, Chima and ete. have 2 or more Chinese spellings. Among these, Neoneol, Ddambatgijeoksam, Nuyeok, Tyeollik, and etc. seem to have used similar Chinese spellings, and Gat, Dongdoljji, and etc. seem to have used Chinese spellings according to the multiple forms in each country. 3. There have also been records of terms seldom used at present such as Dalogi, Neoneol, and etc., and it has been found that Mahulae, Doljji, Dunja, and etc. are the terms have been geographically influenced by the northern race as they have been left as a dialect in North Korea currently. 4. Mahulae, Kulimae, Neolku, and etc. may be inferred as they have originated from Manchu language through pronunciation of each country spelt in translated books.

The theme of the current study is to study intonation of Taiwanese(Tw.) by comparing the intonation patterns in native language (Ll), target language (L2), and interlanguage (IL). Studies on interlanguage have dealt primarily with segments. Though there were studies which addressed to the issues of interlanguage intonation, more often than not, they didn't offer evidence for the statement, and the hypotheses were mainly based on impression. Therefore, a formal description of interlanguage intonation is necessary for further development in this field. The basic assumption of this study is that native speakers of one language perceive and produce a second language in ways closely related to the patterns of their first language. Several studies on interlanguage prosody have suggested that prosodic structure and rules are more subject to transfer than certain other phonological phenomena, given their abstract structural nature and generality(Vogel 1991). Broselow(1988) also shows that interlanguage may provide evidence for particular analyses of the native language grammar, which may not be available from the study of the native language alone. Several research questions will be addressed in the current study: A. How does duration vary among native and nominative utterances\ulcorner The results shows that there is a significant difference in duration between the beginning English learners, and the native speakers of American English for all the eleven English sentences. The mean duration shows that the beginning English learners take almost twice as much time (1.70sec.), as Americans (O.97sec.) to produce English sentences. The results also show that American speakers take significant longer time to speak all ten Taiwanese utterances. The mean duration shows that Americans take almost twice as much time (2.24sec.) as adult Taiwanese (1.14sec.) to produce Taiwanese sentences. B. Does proficiency level influence the performance of interlanguage intonation\ulcorner Can native intonation patterns be achieved by a non-native speaker\ulcorner Wenk(1986) considers proficiency level might be a variable which related to the extent of Ll influence. His study showed that beginners do transfer rhythmic features of the Ll and advanced learners can and do succeed in overcoming mother-tongue influence. The current study shows that proficiency level does play a role in the acquisition of English intonation by Taiwanese speakers. The duration and pitch range of the advanced learners are much closer to those of the native American English speakers than the beginners, but even advanced learners still cannot achieve native-like intonation patterns. C. Do Taiwanese have a narrower pitch range in comparison with American English speakers\ulcorner Ross et. al.(1986) suggests that the presence of tone in a language significantly inhibits the unrestricted manipulation of three acoustical measures of prosody which are involved in producing local pitch changes in the fundamental frequency contour during affective signaling. Will the presence of tone in a language inhibit the ability of speakers to modulate intonation\ulcorner The results do show that Taiwanese have a narrower pitch range in comparison with American English speakers. Both advanced (84Hz) and beginning learners (58Hz) of English show a significant narrower FO range than that of Americans' (112Hz), and the difference is greater between the beginning learners' group and native American English speakers.

The article purpose is 'Reading Chinese translation text as a Korean integrated education for Chinese students'. Although number of foreign students has increased rapidly to the economic growth of Korea, the influence of Korean Wave, and the popularity of Korean popular culture like K-pop at domestic universities but the problems of their curriculum have been found in many places. Korean literary education through novel text has an important place in Korean studies, but literary education is often excluded in Korean language education as a foreign language education. Chinese students already have background knowledge of Korean translation novels through Chinese novels. They can get the learning effect as the Korean language study. Second, they can compared with Korean national violence and Chinese national violence through 'Red Revolution' and understand about Korean-Chinese understanding of the times, social and cultural phenomena, Third, they are able to study the theory of literature itself. also It was the educational purpose pursued by the humanities. Chinese students develop their Korean language skills by studying the Brothers which are translated into Korean, and we can see the similarities and differences of national violence by comparing Korea's '4.19' with China's 'Cultural Revolution' After comparing people, background, dynamics of the space where they are located, we can raise awareness of the historical and social problems of both countries. It is possible to study subjects' memories of space, change of local meaning, the formation of urban space or individual space in the text in the specific space where national violence occurs. In this way, the method of learning Korean integrated education through Brothers of the Chinese translation novels makes an opportunity to look at national violence in the Korean-Chinese space of the 1960s and 1970s. It has a subjective perspective from subordination to the nationality of the modern nation-state. This is an educational effect that can be obtained through reading a Chinese translation novel as a Korean language integrated education.

본 논문에서는 2차원 웨이블릿 변환을 이용한 영상 압축방식에 적합한 블라인드 워터마킹 방식을 제안하고 VHDL(VHSIC Hardware Description Language)을 이용해서 하드웨어로 구현하였다. 워터마킹 알고리즘의 목적은 영상의 조작에 대해 영상의 무결성을 인증하고 조작이 가해졌을 경우에 조작 위치를 판별하는 것이다. 제안된 워터마크 방식은 동영상 압축 시 적용되는 것으로 가정하였으며, 따라서 양자화에 무관하고 실시간으로 삽입 및 추출이 가능하도록 하였다. 웨이블릿 도메인에서 주파수 특성상 최저파수 대역(LL4)은 공간영역의 변화에 대해 민감하지 않다는 것을 실험적으로 검증하여 LL4를 워터마크의 삽입영역으로 설정하였다. 워터마크 삽입 시 압축된 영상의 화질을 최대한 저하시키지 않으면서 강인성을 지닐 수 있는 비트평면 조합을 LL4 부대역에서 선택하고 이를 워터마크 삽입 포인트로 결정한다. 비트평면에서 워터마크의 삽입위치를 알고 있고 값 변환이 아닌 값의 치환방식으로 워터마크를 삽입하므로 워터마크를 추출할 때에 원 영상이 필요하지 않다. 또한 삽입위치가 노출되었을 때의 안전성을 고려하여 워터마크를 블록암호화 알고리즘을 이용하여 암호화한 후 삽입하도록 하였다. 실험결과 제안된 워터마킹 알고리즘은 일반적인 영상의 조작에 대해 강인성을 보였고 영상 및 비디오 압축기에서 전체 동작과 구조에 큰 변화를 주지 않으면서 이식이 가능하였다. 구현된 영상압축기와 워터마킹 하드웨어는 Altera의 APEX20KC EP20K400CF672-7 FPGA 디바이스에서 약 40%의 LSB를 사용하고 최대 약 60MHz에서 동작이 가능하였다.

Objectives : In many cases, patient's symptoms have been recorded on EMR in natural language instead of medical terminologies. It is possible to build a database by analyzing the symptoms of Korean Medicine(KM) that indicates patient's symptoms in natural language. Using the database, when doctors record patient's symptoms on EMR in natural language, conversely it'll be also possible to extract the symptoms of KM from those natural language. The database will enhance the value of EMR as a medical data. Methods : In this study, we aimed to make data structure of the terminologies that represent the symptoms of KM. The data structure is combinations of smallest unit in natural language. We made the database by analyzing morpheme of the natural language to express the symptoms of KM. Results & Conclusions : By classifying the natural language in 15 features, we made the structure of concept and the data available for morphological analysis.

확률문법은 자연어처리에서 사용되며, 확률문법에 대한 구문분석의 결과인 파스는 문법의 확률을 그대로 보존해야 한다. 대표적인 구문분석방법인 LL 파싱과 LR 파싱의 확률파싱 가능성을 살펴볼 때 LL 파싱은 문법의 확률정보를 그대로 유지하는 반면에 LR 파싱은 그렇지 않다. 확률문법과 확률파싱오토마톤과의 관계에 관한 기존 연구로 확률보존조건을 충족하는 오토마톤의 특성에 관한 연구는 진행된 바 있다. 그렇지만, 현재로서는 확률보존조건을 충족하는 오토마톤 생성모델에 관해서는 알려진 바가 없다. 본 논문에서는 단일상태파싱오토마타에 기반한 확률파싱오토마타 모델을 제안한다. 제안 모델로부터 생성되는 오토마톤은 확률보존조건을 보장하기에 별도의 확률파싱 가능 여부를 테스팅하는 단계가 불필요하고, 별도의 확률 함수를 정의하지 않아도 된다. 또한 매개인자를 적절하게 선택하여 효율적인 오토마톤의 생성이 가능하다.
