This study is for looking into distinguishing features in child KSL learners' early literacy development. For these, the writings, recording data of dialogue, and observational journals of KSL child learners was collected regularly and the data were analysed. As results, KSL child learners showed lots of writing errors due to difficulty in phonological awareness or letter awareness of Korean language. And they seemed to develop the competence of connecting letters and meanings prior to developing the competence of connecting letters and sounds. Three KSL child learners showed great individual differences in development rate, and it is supposed to be mainly caused from differences of literacy development in their mother tongue, or quantity and quality in exposure for Korean language.

This study aims to discuss how Egyptian learners of Korean perceive and categorize Korean vowels, how Koreans perceive Korean vowels they pronounce, and how Egyptian learners' Korean vowel categorization affects their perception and production of Korean vowels. In Experiment 1, 53 Egyptian learners were asked to listen to Korean test words pronounced by Koreans and choose the words they had listened to among 4 confusable words. In Experiment 2, 117 sound files (13 test words×9 Egyptian learners) recorded by Egyptian learners were given to Koreans and asked to select the words they had heard among 4 confusable words. The results of the experiments show that "new" Korean vowels that do not have categorizable ones in Egyptian Arabic easily formed new categories and were therefore well identified in perception and relatively well pronounced, but some of them were poorly produced. However, Egyptian learners poorly distinguished "similar" Korean vowels in perception, but their pronunciation was relatively well identified by native Koreans. Based on the results of this study, we argued that the Speech Learning Model (SLM) and Perceptual Assimilation Model (PAM) explain the L2 speech perception well, but they are insufficient to explain L2 speech production and therefore need to be revised and extended to L2 speech production.

변형 규칙 기반 품사 태거는 태깅 규칙을 코퍼스로부터 자동 학습할 수 있고, 견고하며 태깅 결과를 이해하고 분석하기가 쉽다는 장점을 갖는다. 이에 최근 한국어 특성을 고려한 변형 규칙 기반 한국어 품사 태거가 개발되었다. 하지만 이 시스템은 오류 어절의 어휘 정보를 사용하지 않으므로 수정 가능 오류에 대한 변형 규칙이 제대로 학습되지 못하며, 변형 규칙 적용 과정에 새로운 오류를 발생시킨다는 문제점이 있다. 이에 본 논문은 오류 어절의 어휘 정보를 참조할 수 있는 세부변형 규칙 추출을 이용한 변형 규칙 기반 한국어 품사 태거의 개선 방안을 제안한다. 어휘 정보를 참조할 수 있는 세부 변형 규칙의 형태는 특정 문맥 C에서 어절 W의 어절 태그 ${\alpha}$를 어절 태그 ${\beta}$로 변형한다와 같다. 제안된 방법은 약 10만 어절 크기의 학습 코퍼스에서 57개의 세부 규칙을 학습하였고, 2만 어절 크기의 실험코퍼스에 적용한 결과 95.6%의 정확도를 보임으로써 기존의 변형 규칙 기반 품사 태거의 정확도를 약 15.4% 향상시켰다.

There has been many studies to explore what is the best multimedia tools for English learning by internet, but the students are still thirsty for the lack of practical and effective learning method which may lead them to stimulate their motivations to learn English with technological new media. The purpose of this study is to design Flash Animation as a new approach to learn language acquisition for those students who are learning English as a second language. This second is to show the validity for the introduction of Flash Animation into the English class. The third is to describe the effectiveness of the application of multimedia tools used in English communication such as java script programming and power point presentation.

The purpose of this study is to investigate the effects of mobile phone use on university students' English reading achievement and consider the value and effectiveness of mobile phones as a learning tool. The study's subjects were students from a university in Seoul, who were divided into an experimental group (n=37) and a control group (n=43). The experimental group used various mobile phone functions-such as searching, recording, taking photos, using mobile apps, and community uploads-in reading class. The control group, on the other hand, focused on students' presentations and the professor's explanations. Two achievement tests and an open-ended questionnaire were administered. The results revealed that the experimental group scored higher than the control group, which showed a significant difference. In addition, the positive impacts of mobile phone use as reported in the questionnaire were interest and motivation, self-directed learning, and continuous learning beyond time and space. In order to foster efficient second language teaching and learning, learners and also teachers must be aware of the potential value of mobile phones as a learning tool. To encourage more active mobile phone use in the classroom, diverse and interesting class activities using mobile phones should be developed.

The main purpose of this study is to reveal the educational value of the Chinese drama and present a concrete and feasible Chinese speaking teaching-learning programme targeted at intermediate level Chinese learners through storytelling and role-play. There is some advice for Chinese speaking teaching-learning by using Chinese dramas. Firstly, applying various techniques actively such as storytelling and role play, not only could it help to correct Chinese speaking pronunciation, but it could also help students to make up and express their ideas as free as possible. Secondly, it's necessary to accord with the teaching objectives of Chinese speaking, students' actual level and requirements to select Chinese dramas as Chinese speaking teaching-learning materials. Thirdly, it's noteworthy that teachers should select Chinese dramas with various genres or theme according to social development to promote the fun of class and maximize the educational value of Chinese dramas as teaching-learning materials.

제 7차 교육과정부터 규칙성 영역의 학습이 도입되고 중요하게 다뤄지고 있지만, 학생들이 규칙성을 찾거나 도형 패턴을 나타내는 데 어려움을 겪고 있기 때문에, 본 논문에서는 규칙성을 LOGO 프로그래밍 언어를 통해 학습하고 그 효과를 분석하였다. 수학적 패턴의 유형은 생성방식에 따라서 (1) 반복패턴, (2) 대칭패턴, (3) 증가패턴, (4) 회전패턴, (5) 혼합패턴의 다섯 가지이다. 논 논문에서는 규칙성 영역에 대한 LOGO 수업의 효과를 분석하기 위해서, 각각 패턴에 대하여 평가 문항을 만든 후 수업전과 LOGO를 통한 수업 후에 평가를 실시하여 분석하였다. 사전평가 M 4.74에서 LOGO 수업을 실시 한 후에 평가에서 M 5.22로 LOGO 수업의 효과가 유의미(p<.05, p=0.016)하게 나타났다. 특히, 도형패턴에서 높은 향상도를 나타냈다.

이 글은 제2회 서울 국제 음성학 학술대회(SICOPS 2000) 기조강연 내용을 조금 손질한 것인데, 한국인 영어 학습자가 저지르기 쉬운 발음상 잘못을 모음, 자음별로 관찰하고 그 대책을 논의한다. 모음에서는 주로 i:l, u:$-\sigma$, (equation omitted) 흔동이 문제이며, 또한 90종이 넘는 여러 철자로 나타나는 쭉정모음(schwa) 식별과 정복한 발음도 큰 문제다. 자음에서는 음소 연결방식에서 생기는 자음접변 둥 한 국어 특유 현상을 영어에까지 연장하는 바람에 많은 오류가 생긴다는 것과 영어 sp-, st-, sk-에서 /p t k/는 연한소리(lenis)로 [(equation omitted)]인데, 된소리로 잘못알고 있는 수가 많다는 것도 지적된다. 무룻 영어학습자는 철자만 보고 발음을 속단하지 말고 단어마다 반드시 발음을 사전에서 확인할 것과 아울러 거기에 음성학적 훈련이 수반되어야 함을 역설하며, 정확한 발음을 아는 것은 실제 영어 청취i구사에 뿐 아니라 또한 언어연구 기초확립에 필수적이라는 말로 글을 맺는다.

음성 및 문자를 통한 컴퓨터와의 정보 교환을 위한 통합 사용자 인터페이스 (Intelligent Man- Machine interface) 시스템의 일환으로 한국어 단모음의 인식을 위한 시스템을 인공 신경망 모델을 사용하여 구현하였으며 인식시스템의 상위 접속부에 필요한 단어 인식 모듈에 있어서의 인지 실험도 행하였다. 모음인식의 입력으로는 제1, 제2, 제3 포르만트가 사용되었으며 실험대상은 한국어의 [아, 어, 오, 우, 으, 이, 애, 에]의 8 개의 단모음으로 하였다. 사용한 인공 신경망 모델은 Multilayer Perceptron 이며, 학습 규칙은 Generalized Delta Rule 이다. 1 인의 남성 화자에 대하여 약 94%의 인식율을 나타내었다. 그리고 음성 인식시의 인지 현상 실험을 위하여 약 20개의 단어를 인공신경망의 어휘레벨에 저장하여 음성의 왜곡, 인지시의 lexical 영향, categorical percetion등을 실험하였다. 이때의 인공 신경망 모델은 Interactive Activation and Competition Model을 사용하였으며, 음성 입력으로는 가상의 음성 피쳐 데이타를 사용하였다.

This study aimed to investigate the effect of Chinese on the production of Korean rhythm. Korean and Chinese are typologically classified into different rhythmic categories; because of this, the phonological properties of Korean and Chinese are similar and different at the same time. As a result, Chinese can exert both positive and negative influences on the realization of Korean rhythm. To investigate the influence of the rhythm of the native language of L2 learners on their target language, we conducted an acoustic analysis using acoustic metrics like of the speech of 5 Korean native speakers and 10 advanced Chinese Korean learners. The analyzed material is a short paragraph of five sentences containing a variety of syllable structures. The results showed that KS and CS rhythms are similar in %V, VarcoV, and nPVI_S. However, CS, unlike KS, showed characteristics closer to those of a stress-timed language in the values of %V and VarcoV. There was also a significant difference in nPVI_V values. These results demonstrate a negative influence of the native language in the realization of Korean rhythm. This can be attributed to the fact that all vowels in Chinese sentence are not pronounced with the same emphasis due to neutral tone. In this sense, this study allowed us to observe influences of L1 on L2 production of rhythm.
