The study was conducted to find out lexical complexity and syntactic complexity for Korean learners by telling stories to see pictures. The results were as follows. First, there was no meaningful difference according to nationality. Second, we checked the differences on lexical complexity and syntactic complexity according to Korean studying period, only number of difference words showed meaningful difference among lexical complexity sub variables, but there was no difference among syntactic complexity sub variables. Third, we also checked correlation among staying period of Korea, Korean studying period, and other language related variables. It showed meaningful correlation staying period in Korea and other language related variable except Korean studying period and TTR. The directions for teaching Korean learners were suggested on the point of converge view according to results.

본 논문에서는 최근에 외국어로서의 한국어 학습 수요가 증가하고 있는 현실을 반영하여, 한국어를 외국어로 사용하는 한국어 수요자의 접근성을 고려한 초보적인 한국어 읽기 학습을 지원하는 학습지원 시스템을 설계하여 제시한다. 우리나라는 경제개발에 성공하고 주요 기간산업에서 세계적인 기업이 탄생하여 세계적으로 관심을 끌고 있다. 이런 현상에 따라서 결혼 이민자는 물론 국내 산업체에 취업하기 위해 입국하는 동남아시아를 중심으로 하는 근로자는 물론 첨단산업에 종사하기 위해 고학력의 외국인들이 많이 입국하고 있으며, k-pop을 비롯한 '한류'에 대한 관심이 고조되어, 다양한 국가의 다양한 계층에서 한국어에 대한 관심이 증가하고 있다. 이와 같은 현실에 비하여 특히 경제력과 학습수준이 낮은 외국인들은 정규적인 교육의 기회를 갖지 못하게 되어 여러 가지의 문제를 야기하고 있다. 이런 현실을 반영하여 초보적인 한국어 학습, 특히 읽기 학습을 지원하는 한국어 이러닝 시스템을 설계하여 제시하였다.

The current study seeks to understand the multi-faceted desires of language learners through the theoretical lens of imagined communities (Norton, 2001). Particularly, the study focuses on the learners of Korean language-one of the less commonly taught languages in the U.S. that has received relatively less attention in previous literature on second language motivation. The study analyzed and compared the narratives told by eleven Korean language learners in a post-secondary language program, and identified four types of imagined communities: Communities of K-pop Culture, Communities of Professionals, Communities of Korean Family and Relatives, and Communities of ethnic Koreans. The study found that these imagined communities were not restricted to a specific region or an ethnic group but encompassed various populations connected through the use of Korean language. The study also found variability within what has been readily labelled as heritage motivation (or motivation related to heritage), as well as striking differences between heritage language learners and non-heritage language learners in terms of their scope of imagination.

The purposes of this study are (1) to see if the length of residence in Korea affects to the VOT values of Korean plosives produced by Chinese speakers (2) to investigate if such VOT values are different in non-sense words and real words and (3) to find out how such VOT values are related to the native Korean speakers' understanding of the words. For these purposes, eighteen Chinese speakers' VOT values of Korean plosives were measured using Speech Analyzer and their pronunciations were evaluated by three native Korean speakers. The results show that there is no effect of both (1) length of residence in Korea and (2) production of non-sensed words and sensed words. In addition, it is noticed that VOT values of some plosives affect more to the native Korean speakers' understanding of the words, while some are not.

The purpose of present study tested the effects of context, transparency, familiarity and related variables on comprehension of 32 idioms in 87 Chinese learners of Korean who were attending the S university in Jeonnam providence. In the first assessment, idiomatic phrases were presented out of context. In another assessment, idiomatic phrases were embedded in supportive story contexts. To examine the difference based on task types, paired t-test or one-way ANOVA was used to test differences on related variables such as TOPIK, years of residence in Korea, major and etc. on idiom comprehension. The results of this study are summarized as follows. First, task type, familiarity and transparency were found to have no significant effect on idiom comprehension for Chinese learners of Korean. Second, the related variables such as TOPIK, and major had a significant effect on idiom comprehension. Third, percentage of context related interpretation error in context task was the highest. Literal interpretation errors were followed by it. It means they have a tendency to use contextual cues and semantic analysis of the phrase to comprehend Korean idioms. The results of study will be used to make a plan for teaching Chinese learners of Korean.

For Korean learners, writing is a harder part than any other areas in Korean languages. But in the future, the ability to organize and write systematically is essential for future koran languages learners to take classes, do assignments and presentations at school, and then adapt to job situations. Therefore, there is a need to devise a direction for this. In general, writing characteristics are viewed in many ways, including writing productivity, writing complexity, and writing errors. Accordingly, the study provided drawings and A4 paper for Vietnamese Korean learners, Chinese Korean learners, and Korean university students, before writing freely. Based on the their writing results, we looked at syntax factors (total C-units, total number of words), syntax complexity (number of words per C-unit and clause density), and writing errors (postposition, spell errors, and connective suffix, space errors) According to the study, Vietnamese and Chinese Korean language learners showed significantly lower syntax productivity and complexity than Korean university students, and showed more writing errors than Korean students in postposition and clause density. Based on the results of the study, we discussed writing guidelines for Korean languages learners. However, this study did not validate the differences in writing characteristics according to the Korean language level and length of residences for the study subjects. Therefore, it is necessary to consider this in future research.

자연스럽고 명료한 한국어 Text-to-Speech 변환 시스템을 위해서 음소의 지속 시간을 제어하는 일은 매우 중요하다. 음소의 지속 시간은 여러 가지 문맥 정보에 의해서 변화하므로 제어 규칙에 의존하기 보다 방대한 데이터베이스를 이용하여 통계적인 기법으로 음소의 지속 시간에 변화를 주는 요인을 찾아내려고 하는 것이 지금의 추세이다. 본 연구에서도 트리기반 모델링 방법중의 하나인 CART(classification and regression tree) 방법을 사용하여 회귀 트리를 생성하고, 생성된 트리에 기반하여 음소의 지속 시간 예측 모델과, 자연스러운 끊어 읽기를 위한 휴지 기간 예측 모델을 제안하고 있다. 실험에 사용한 음성코퍼스는 550개의 문장으로 구성되어 있으며, 이 중 428개 문장으로 회귀 트리를 학습시켰고, 나머지 122개의 문장으로 실험하였다. 모델의 평가를 위해서 실제값과 예측값과의 상관관계를 구하였더니 음소의 지속 시간을 예측하는 회귀 트리에서는 상관계수가 0.84로 계산되었고, 끊어 읽는 경계에서의 휴지 기간을 예측하는 회귀 트리에서는 상관계수가 0.63으로 나타났다.

In South Korea nowadays, Among the married immigrant women in Korea, the proportion of long-term residents living in Korea for more than 10 years is increasing continuously(48%), while the proportion of short-term residents who are under 5 years is decreasing(16%). However, Korean language education and related research in the Marriage and Immigration Women's Center are still focused on the initial immigrants. Therefore, we should classify married immigrant women according to their stay time in Korea, so that Korean language education and teaching materials need to be more diversified. This study focuses on married immigrant women with intermediate and advanced Korean proficiency and chooses a catalogue of Chinese characters idioms to explore the possibility and educational value of using Chinese characters Idioms in Korean education. According to the research results, Chinese characters idiom education can help married immigrant women in Korean language learning and information acquisition, interpersonal relationships and life attitudes, cultural understanding and social adaptation, child rearing and learning guidance. This is the important part of Korean language education that needs to be guided by married immigrant women. Based on this, 130 Chinese characters idioms in Korean language education and textbook development centered on married immigrant women were selected and catalogue edited in four stages. It is hoped that the results of this study will serve as a reference for Korean language education research and textbook development for married immigrant women in the future.
