Purpose - This study focused on the development of a Korean language curriculum to solve the problem of Korean literacy among students from multicultural families. Research design, data, and methodology - A case study was conducted on Sim(2018)'s learner-centered learning model to develop an educational plan including AI technology, which will help students from multicultural families to effectively improve their communication and learning skills by improving their reading, writing, and speaking of Korean. Result - Total of six educational plans using AI technology (Microsoft PowerPoint's drawing function, AutoDraw, and Google's Four-cut cartoons) were developed. Conclusion - The curriculum using AI is expected to greatly contribute to the recovery of language learning ability and confidence in studies necessary to improve learners' language education.

The purpose of this study was to provide a better understanding of foreign-born Korean children's early school adjustment in the U.S. The interaction between the foreign-born Korean children in the U.S. and several of the children's microsystems, including family, school, and peer was assessed to meet this purpose. The study subjects were 43 foreign-bom Korean children who were sampled from Korean Sunday Language schools and who attended local schools in the Boston area, MA, USA. Quantitative analysis was conducted to identify which variables of interest predicted the early adjustment of this group of children. Furthermore, in-depth interviews were conducted with mothers of the children from the top and bottom groups 1) the most successful (in the top quartile) and 2) the least successful adjustment groups (in the bottom quartile) sorted by scores on the Peabody Picture Vocabulary Test-Revised (PPVT-R). The interview results were analyzed to elicit maternal perceptions/beliefs on education, in general, and those of home-school relationships, in specific. Several conclusions can be drawn from both the quantitative and qualitative analyses. The results of multiple regression and path analysis showed that the children's language development predicted their adjustment, but the effects of the other two variables, peer relationships and school experiences, on the adjustment of children, were mediated through the children's language. Moreover, common themes and patterns in the responses to a series of open-ended questions emerged from the interviews with the two groups of mothers. The two mothers of the least successful group were concerned about their children's future and school success, but thev did not show anv responsive attitudes toward achieving this goal. By contrast, the mothers from the most successful group were self-determined with regard to their children's education and had strong beliefs and values on how to raise their children in the new culture. The implications were discussed.

High-level synthesis (HLS), which automatically synthesizes a register-transfer level (RTL) circuit from a behavioral description written in a high-level programming language such as C/C++, is becoming a more popular technique for improving design productivity. In general, HLS tools often generate a circuit with a larger area than those of hand-designed ones. One reason for this issue is that HLS tools often generate multiple instances of the same module from a function. To eliminate such a redundancy in circuit area in HLS, HLS tools are capable of sharing modules. Function-level module sharing at a behavioral description written in a high-level programming language may promote function reuse to increase effectiveness and reduce circuit area. In this paper, we present two HLS techniques for module sharing at the function level.

GPU를 이용한 병렬 알고리즘은 어떤 메모리를 사용하는지에 따라 시스템의 전체적인 성능이 달라진다. 본 논문은 GPU 환경에서 실행되는 CUDA 프레임워크에서 병렬처리를 이용하여 문서 분류 시스템의 속도를 향상시키고자 할 때 메모리 로딩 시간이 전체적인 시스템의 성능에 미치는 영항을 연구하였다. 기존의 CPU 환경에서 구현했을 때와 비교하여 어느 정도의 성능 향상이 있었는지 실험하였으며 이전 연구에서 고려하지 않았던 메모리를 읽는데 걸리는 시간을 고려하여 현실적인 실행 시간을 비교하였다. 실험 결과에 의하면 CPU 에서 구현했을 때의 연산 속도보다 GPU의 텍스쳐 메모리를 사용하여 구현하였을 때 문서분류 성능이 향상되는 효과가 있음을 알 수 있었다.

기존의 표절 검사 소프트웨어의 경우에는 수행 시간이 지나치게 오래 걸리거나 표절의 의미가 희박한 구간들을 찾는 등의 문제가 있었다. 본 논문은 대학에서 과제물 표절 검사에 활용할 수 있는 소프트웨어인 CopyCheck을 설계 및 개발하였다. CopyCheck은 각각의 대상 문서로부터 문서 고유의 시그니처 세트를 추출 비교하여 표절이 의심되는 문서들 간의 중복 인텍스 세트를 만들어 의심 구간들을 추려낸 다음 지역 정렬 방법을 이용하여 일치 구간을 찾아내는 방법으로 많은 문서들을 대상으로도 표절 구간들을 빠르게 찾아낸다.

This study surveyed L2 learners' needs for different components of communicative competence. It aimed to determine what abilities the learners strongly need to achieve communicative competence in different learning contexts. It also examined gender differences in the learners' need for phonological competence. A total of 359 students participated in this study, divided into three learner groups: high school, vocational college, and university students. The data were collected via a questionnaire, which was based on Bachman's (1990) framework of language competence. The study drew some important findings: (a) The vocational trainees expressed a stronger need for illocutionary competence than the high school students and for sociolinguistic competence than the high school and the university groups; (b) The high school and the university groups equated grammatical, textual, illocutionary, and strategic competences in their needs with lesser attention to sociolinguistic competence; (c) To the high school and the university groups, pragmatic competence was assessed higher than organizational competence; (d) Female students showed greater sensitivity to pronunciation ability than did male students. On the basis of these results, pedagogical implications are discussed, along with some helpful suggestions.

The goal of this study was to examine the correlations of stress coping strategies and cultural, psychological and school adjustment among Korean early study-abroad adolescents in the United States. Participants were 437 Korean early study-abroad adolescents aged 15 to 18 years old enrolled in summer language institutes located in Seoul and Gyeonggido, South Korea. The survey consisted of questionnaires relating to coping strategies and, cultural, psychological and school adjustments. The data was collected during the break time of summer language institute classes. Results showed that these adolescents' problem focused and social support coping strategies were positively related with acculturation, psychological adjustment and school adjustment, and emotion focused coping strategy was positively related to satisfaction of life.

As the Communicative Approach has become the norm in foreign language teaching, the objectives of teaching English in school have changed radically in Korea. The focus in high school English textbooks has shifted from mere mastery of structures to communicative proficiency. This paper will study five polysemous words which appear in twelve high school English textbooks used in Korea. The twelve text books are incorporated into a single corpus and analyzed to classify the usage of the selected words. Then the usage of each word was compared with that of three other corpora based sources: the BNC(British National Corpus) Sampler, ICE Singapore(International Corpus of English for Singapore) and Collins COBUILD learner's dictionary which is based on the corpus, "The Bank of English". The comparisons carried out as part of this study will demonstrate that Korean text books do not always supply the full range of meanings of polysemous words.

This study is to examine the relationship of HOME and personality with Preschool children's school readiness. The subjects were 138 children(4 to 6 year-old) and their mothers in Seoul, Gyunggi-do, and Chungnam. The instruments for this study were Cooperative Preschool Inventory(CPI), The Home Observation for Measurement of the Environment(HOME), and Children's Personality Test. The data were analyfed by Pearson's r, stepwise regression, ANOVA, Scheffe test for the post hoc test, and Cronbach a for the reliability in SPSS PC program. The major findings with the preschool children's school readiness were as follows. 1) That was significant correlations with HOME(language environment and encouragement of independence) and personality(sociability and familiarity). 2) That was explained significantly by sociability, encouragement of independence, language environment, and stimuli for development. 3) That was no sex-difference and was an increase by age. 4) There were significant differences in preschool children's school readiness, HOME, and personality by familial demographic variables.
