Structures of stories, paragraphs, and sentences and inferences applied to indexing and searching were studied to construct the full-text and sentence retrieval system for storytelling. The system designed the database of stories, paragraphs, and sentences and the knowledge-base of inference rules to aid to write the story. The Knowledge-base comprised the files of story frames, paragraph scripts, and sentence logics made by mark-up languages like SWRL etc. able to operate in semantic web. It is necessary to establish more precise indexing language represented the sentences and to create a mark-up languages able to construct more accurate inference rules.

Looking at the understanding of scientific concepts from a linguistic perspective, it is very important for students to develop a deep and sophisticated understanding of words used in scientific concept as well as the ability to use them correctly. This study intends to provide the basis for productive knowledge education of scientific words by noting that the foundation of productive knowledge teaching on scientific words is not well established, and by exploring ways to teach the relationship among words that constitute scientific concept in a productive and effective manner. To this end, we extracted the relationship among the words that make up the scientific concept from the text of science textbook by using quantitative text analysis methods, second, qualitatively examined the meaning of the word relationship extracted as a result of each method, and third, we proposed a writing activity method to help improve the productive knowledge of scientific concept words. We analyzed the text of the "Force and motion" unit on first grade science textbook by using four methods of quantitative linguistic analysis: word cluster, co-occurrence, text network analysis, and word-embedding. As results, this study suggests four writing activities, completing sentence activity by using the result of word cluster analysis, filling the blanks activity by using the result of co-occurrence analysis, material-oriented writing activities by using the result of text network analysis, and finally we made a list of important words by using the result of word embedding.

Pure functional languages have the referential transparency feature sothat all objects cannot be updated destuctively. Once an aggregated data structure such as array is updated, both the original and newly updated array must be preserved to maintain reverential transparency. Thus, it is required to develop an efficient mechanism with which can reduce the maintenance cost while maintaining referential transparency for whole data. This study is to suggest a functional array to solve the problem, and them test it. For that, the proposed mechanism was implemented on a combinator graph reduction machine. The result shows that proposed mechanism reduces traversal time for array operations. Also, updating all versions and accessing the recent version are achieved in constant time without reconstruction of updated data in execution time.

The purpose of this study is to explore the selection attributes for parents of children with language disability when choosing a clinic. The data collection was carried out in 3 steps: the preliminary survey, first open survey and second survey in AHP(Analytic Hierarchy Process). The subjects of were 252 in total. The results were as follows: First, The order of priority attributes in superior categories for parents of children with language disability when selecting a clinic were 'therapist-related attributes', 'program-related attributes' and 'physical-related attributes' in turn. The top 5 priority attributes in subcategories were 'therapist's academic background and major', 'ability to make a rapport', 'clinical experience and qualification of therapist', 'kindness and confidence' and 'counseling program for parents'. Second, The parents of preschoolers age 6 and younger chose 'clinical experience and qualification of therapist', 'counseling program for parents' and 'learning materials' for the most priority attributes, whereas the parents of students age from 7 to 12, considered 'therapist's academic background and major', 'clinical fee' and 'distance transport parking' more importantly to select a clinic. The results of this study provided preliminary data for successful planning of speech and language therapy.

The purpose of this study was to explore the experience in cultural competence of multicultural counselors working with female immigrants by marriage. In-depth interviews, followed by a phenomenological analysis, were conducted on 10 multicultural counselors. 6 themes were emerged from data analysis: facing difficulties due to linguistic and cultural differences, feeling doubts about self and one's ability, reflecting self, putting efforts to learn other cultures and groups, realizing changes, and feeling insecure still. 3 categories appeared from the 6 themes above: difficulties, efforts to change, and change and limitations. Based on the results, social work suggestions for increasing cultural competence of multicultural counselors were discussed.

The importance of small group activity has recently been emphasized in the gifted education in science because of the increased needs to foster the human resources that could explore through the communication and collaboration. In this study, we investigated the characteristics of the verbal interaction according to the learning styles of the gifted-students in science in the small group activity and examined how learning style affected the interaction within a group in order to seek an effective grouping strategy. The competition, cooperative, and dependent students with learning style in the small group 1 and the cooperative, cooperative, dependent students in the small group 2 were assigned by the 6 science high school students. The analyses of the results revealed that the small group 1 showed the asymmetric interaction of the low level, whereas the small group 2 showed the symmetric interaction of the high level. In other words, the frequencies of in-depth interaction in the small group 2 were higher than those in the small group 1, and also students in the small group 2 were equally involved in the activity rather than the small group 1. These results suggested that the grouping by the students' learning styles in the small group activity should affect significantly the participation decision in activity and the level of verbal interaction. Educational implications of theses findings were discussed.

최근 발생한 수많은 표절 논란으로 인해 많은 유사 문서 탐색 시스템이 개발되어 사용되고 있다. 많은 시스템 중 내용기반 유사문서 탐색 시스템인 DeVAC은 대용량 문서 1:1간의 비교에서 빠른 성능을 보여주지만 수천~수만 개의 문서 집합에 대해서는 적절한 성능을 보여주지 못한다. 이를 해결하기 위해 전역 사전(Global Dictionary)을 이용한 전처리 방법이 고안되어 적용되었다. 이 전처리 방법을 통해 비교해야 할 문서쌍이 줄어들고 전체 시스템의 성능을 향상시킬 수 있다는 것은 밝혀졌으나, 전처리를 위해 발생하는 추가 비용에 대한 계측이 이루어지지 않았을 뿐 아니라 문서 쌍이 얼마나 감소하는지 측정한 실험에서도 언어 처리용 실험적 데이터(말뭉치)에 대한 실험이 대부분을 차지하였기 때문에 실제 데이터에 대해 어떤 성능을 보일지 정확히 예측할 수 없었다. 본 논문에서는 전체 시스템에서 전처리를 위해 필요한 모든 추가 비용을 측정하고, 데이터를 1.5Gb, 6263개의 문서로 이루어진 실존하는 문서 집합으로 구성하여 성능 향상 정도를 측정함으로써 실제 데이터에 대한 전처리 신뢰도를 예측하였다. 실험 결과 전처리 후 찾아낸 유사한 문서 쌍을 전처리를 하지 않을 경우의 80~89.3% 정도로 유지하면서 검사 시간을 기존의 10.8%~15.4% 수준으로 대폭 감소시킬 수 있었다.

The purpose of this study is to explore the Nature of Argumentation in Science education (NAS). For this purpose, we collected previous studies conducted on the argumentation in science education, and then collected previous studies were analyzed to extract the overall characteristics of argumentation in science education. Based on the results, an expert review was conducted, then the nature of argumentation in science education was finally derived to a total of seven components: 'evidence based', 'linguistic interaction', 'context dependency', 'public decision-making', 'tentative agreement', 'methodological diversity', and 'enculturation of scientific culture'. Understanding the nature of argumentation in science education can promote the practice of argumentation in science learning. Therefore, further studies will be necessary to conduct research to expand and refine the nature of argumentation in science education in order to effectively practice it in science learning.

For an application of ontology, query processing is mandatory field for efficient information search in the ontology. Other query processing systems tend to analyze only facts and to simply provide structural information for users. In fact, the systems do not have big difference with database systems or text based information processing systems. Therefore, in this research, the method which can provide the inferred information based on axioms is suggested in order to maximize reusability of ontology.

개인용 컴퓨터가 많이 보급되고, CD-ROM과 같은 대용량의 기록장치가, 널리 퍼지면서, 전자화된 사전이 널리 사용되게 되었다. 그러나 이러한 전자사전들은 대개 매우 단순화된 탐색기능만을 제공하므로, 전자화의 잇점을 크게 살리지 못하고 있다. 따라서, 컴퓨터의 힘을 빌린, 보통의 종이로된 사전보다 훨씬 유용한 전자사전을 생각해 볼 수 있을 것이다. 이러한 노력이 과거 80년대 말에 하이퍼텍스트로 시작되어 이제는 매우 상업적인 곳에까지 사용되어지고있다. 국내에서도 전자사전의 개발은 다양하게 진행되어오고 있으나, 대부분 컴퓨터를 위한 사전, 다시 말하면, 빠른 접근시간, 적은 메모리사용만을 고려한 사전에 그치고 있다. 본 논문에서는 이러한 필요성에 부합하여, 백과사전자료를 가지고 사람을 위한 전자백과사전을 개발하는 방법을 소개한다. 특히, 이러한 개발과정을 자동화 할 수 있음을 보이고, 백과사전을 하이퍼텍스트로 자동변환하는 방법을 자세히 기술한다. 이 방법은 원시 자료를 하이퍼텍스트로 변환하기 좋은 정형화된 중간자료로 바꾸고, 이 중간자료와 기초적인 명사추출 알고리즘을 이용하여, 각 노드들 사이에 링크를 만드는 것이다. 또한, 이 방법을 이용하여 개발한 HE(Hypertext Encyclopedia) 시스템을 소개한다.
