본 연구의 목적은 중국계 결혼이주여성들이 자신의 모국어인 중국어를 자녀들에게 제2언어로 교육하지 못하는 원인을 그들의 경험을 통하여 탐색하고 이에 대한 개선방안을 제시하는 것이다. 이를 위해 2017년 3월부터 2017년 6월까지 한국 거주한지 10년 이상 된 중국인 결혼이주여성 4명을 대상으로 심층인터뷰를 하고 그 내용을 분석하였다. 분석한 결과 결혼이주여성들이 자녀들에게 자신의 모국어를 교육하지 못하는 요인은 크게 네 가지로 나타났다. 첫째, 결혼이주여성 자신이 한국 환경에 적응하기 바빠 어려서부터 자녀에게 모어 가르치는 것을 소홀히 하였다. 둘째, 자녀들이 한국에서 살아가야하기 때문에 중국어보다 한국어교육에 더 많이 신경 쓰고 있었다. 셋째, 어머니 나라의 부정적인 인식 때문에 어머니의 모어를 배우려하지 않았다. 넷째, 한국인들의 부정적인 인식 때문에 당당하게 자신의 언어와 문화를 교육 시킬 수 없었다. 이와 같은 결과를 통하여 결혼이주여성들이 자녀들에게 모어를 가르쳐줄 수 있는 학습기회와 환경을 마련되길 기대한다.

Do loanword properties emerge in the acquisition of a foreign language and if so, how? Classic studies in adult language learning assumed loanword properties that range from near-ceiling to near-chance level of appearance depending on speech proficiency. The present research argues that such variations reflect different phonological types, rather than speech proficiency. To investigate the difference between learner speech and loanword phonology, the current research analyzes the speech data from five different proficiency levels of 92 Korean speakers who read 19 pairs of English words and sentences that contained loanwords. The experimental method is primarily an acoustical one, by which the phonological cause in the loanwords (e.g., the insertion of [$\Box$] at the end of the word stamp) would be attested to appear in learner speech, in comparison with native speech from 11 English speakers and 11 Korean speakers. The data investigated for the research are of segment deletion, insertion, substitution, and alternation in both learner speech and the native speech. The results indicate that learner speech does not present the loanword properties in many cases, but depends on the types of phonological causes. The relatively easy acquisition of target pronunciation is evidenced in the cases of segment deletion, insertion, substitution, and alternation, except when the loanword property involves the successful command of the target phonology such as the de-aspiration of [p] in apple. Such a case of difficult learning draws a sharp distinction from the cases of easy learning in the development of learner speech, particularly beyond the intermediate level of proficiency. Overall, learner speech departs from loanword phonology and develops toward the native speech value, depending on phonological contrasts in the native and foreign languages.

한국에서 청각장애인은 지체장애인에 이어 두 번째로 많은 등록 장애인 그룹이다. 하지만 수어 기계 번역은 시장 성장성이 작고, 엄밀하게 주석처리가 된 데이터 세트가 부족해 발전 속도가 더디다. 한편, 최근 컴퓨터 비전과 패턴 인식 분야에서 트랜스포머를 사용한 모델이 많이 제안되고 있는데, 트랜스포머를 이용한 모델은 동작 인식, 비디오 분류 등의 분야에서 높은 성능을 보여오고 있다. 이에 따라 수어 기계 번역 분야에서도 트랜스포머를 도입하여 성능을 개선하려는 시도들이 제안되고 있다. 본 논문에서는 수어 번역을 위한 인식 부분을 트랜스포머와 3D-CNN을 융합한 3D-CvT를 제안한다. 또, PHOENIX-Wether-2014T [1]를 이용한 실험을 통해 제안 모델은 기존 모델보다 적은 연산량으로도 비슷한 번역 성능을 보이는 효율적인 모델임을 실험적으로 증명하였다.

The four skills of a language are basically required for a communication. They are very important for a learner to develop the balanced language acquisition. Today both listening and speaking skills are emphasized in the global era rather than reading and writing proficiencies. The reason is really why the learners' communicative competence is more needed than the accurate knowledge of a structure in the language. For this reason, the listening comprehension should be taught effectively using the following strategies. First, the sound difference of a language must be taught. Language is a complicated process to convey the comprehensive meaning combined with the internal and external factors of a language. In other words, the meaning for the sound of language should be transmitted by the unit of vocabulary and syntax. Second, a good listening comprehension requires the familiarity and much experience with a lot of English words to understand English sentences unconsciously. Third, as understanding the structure of language is effective for the listening comprehension, the better listening comprehension can be possible through the meaningful exercise. Fourth, the compound process of listening comprehension requires the comprehensive understanding of language, but not the separate understanding of language. Fifth, the appropriate application of the multimedia courseware helps improve the listening comprehension better than that of the existing audio, video, tape recorder and so on. Using multimedia courseware is useful as follows: A learner is able to take as much lesson as he/she wants. It does take little time to repeat about what he/she takes a lesson. It gives the lively picture with the native speakers' voices. It gives him/her(a learner) a feedback effect continuously through the interaction of computer. It controls his/her lesson in accordance with the level of a learner.

The purpose of this study is to investigate the effects of multimedia-assisted language learning on vocabulary learning and attention for elementary school students who are ADHD-prone. Among thirty-three students attending a private English academy in Daegu, four students who were prone to develop ADHD were chosen for this study. They were observed in a multimedia-assisted language learning class for four months and they were given a series of tests designed to measure their attention period and vocabulary ability. The results of the study are as follows. First, studying English by using multimedia was effective in improving the attention of those children prone to develop ADHD. Second, studying English through multimedia was effective in improving their vocabulary ability. Based on the findings, some pedagogical suggestions have been made for further study.

Of interest to second language researchers and classroom teachers today is whether and in what wats formal instruction can promote the development of appropriate use of the target language. Most formal instruction is closely related with the use of textbooks in ESL classrooms, so this study focuses on ESL textbooks. In order to learn to communicate successfully, students should use textbooks which specify the rules of language use for the community in which they are operating. This study examines the speech acts of compliment across 8 middle school English textbooks published in Korea. This study analyses the speech acts of compliment according to the following criteria : 1) vocabulary - adjective, verb, intensifier 2) sentence pattern 3) social strategy - invitation to talk, greetings, farewells, expression of gratitude, etc. 4) types of response. As a result of this study some suggestions is giver to promote the development of appropriate use of English through English textbooks.

For educational and research purposes, a Korean speech recognition platform is designed. It is based on an object-oriented architecture and can be easily modified so that researchers can readily evaluate the performance of a recognition algorithm of interest. This platform will save development time for many who are interested in speech recognition. The platform includes the following modules: Noise reduction, end-point detection, met-frequency cepstral coefficient (MFCC) and perceptually linear prediction (PLP)-based feature extraction, hidden Markov model (HMM)-based acoustic modeling, n-gram language modeling, n-best search, and Korean language processing. The decoder of the platform can handle both lexical search trees for large vocabulary speech recognition and finite-state networks for small-to-medium vocabulary speech recognition. It performs word-dependent n-best search algorithm with a bigram language model in the first forward search stage and then extracts a word lattice and restores each lattice path with a trigram language model in the second stage.

The advanced techniques for video processing and computer graphics enables a sign language education system to appear. the system is capable of showing a sign language motion for an arbitrary sentence using the captured video clips of sign language words. In this paper, a method is suggested which generates the frames between the last frame of a word and the first frame of its following word in order to animate hand motion. In our method, we find hand locations and angles which are required for in between frame generation, capture and store the hand images at those locations and angles. The inbetween frames generation is simply a task of finding a sequence of hand angles and locations. Our method is computationally simple and requires a relatively small amount of disk space. However, our experiments show that inbetween frames for the presentation at about 15fps (frame per second) are achieved so tat the smooth animation of hand motion is possible. Our method improves on previous works in which computation cost is relativey high or unnecessary images are generated.

The purpose of this paper is to examine how Chinese speakers realize Korean prosodic phrases in the reading of Korean texts. Prosodic phrase, in this study, is defined as basic unit of spoken language which can be perceived as purely separate phonetic unit by both hearer and speaker, and is realized with a coherent intonational configuration. Prosodic phrase plays an important role in both speech production and perception. In the second language acquisition, prosody influences the accuracy and fluency of spoken language. The main purpose of this study is to describe the aspect of syntagmatic operation of prosody that produces prosodic phrases. We have specifically examined the relations between the prosodic phrase's boundary and its syntactic status. Furthermore, we examined internal syntactic structure of each prosodic phrase. And the results of each analysis were compared to the aspects of prosodic phrases' formation produced by native Korean speakers. The results show that Chinese speakers tend to coincide the prosodic phrases with syntactic structure more than native Korean speakers.
