XML 문서를 효과적으로 관리하고 검색하기 위한 다양한 XML 질의 언어에 대한 연구가 활발히 수행되고 있지만 다양한 XML 질의 언어의 구문은 일반 사용자들이 숙지하는데 어려움이 있고, 또한 텍스트 형태의 XML 문서는 계층적인 구조로 되어있어 이러한 XML 문서의 구조를 알아야만 질의를 할 수 있다는 문제점이 있다. 따라서 본 논문에서는 복잡한 XML 질의어 구문과 질의 대상인 XML 문서의 구조를 동시에 시각화하고, 사용자와의 상호작용을 통해 질의문을 자동으로 생성하고자 한다. 이를 위해 본 논문에서는 다음과 같이 세 가지 컴포넌트를 기반으로 자동 질의어 생성을 위한 visual query interface를 제안하였다. 이 컴포넌트는 계층적 XML 문서 구조를 보여주는 XML structure viewer, 질의에 사용되는 연산자들을 아이콘화한 operator panel, 그리고 이 두 컴포넌트의 상호작용으로 작성된 질의 구문을 문법적으로 검사하기 위한 query statements panel로 구성된다. 이를 통해 다양한 계층적인 XML 문서의 구조와 복잡한 XML 질의 언어의 구문에 대해서 잘 모르는 초보자라 하더라도 쉽게 XML 문서 상에서 질의를 할 수 있다.

In this study, we analyzed the form, presentation, and interactivity of external representations presented in the matter units of elementary school science digital textbooks developed under the 2015 Revised National Curriculum. The analytic framework of the previous study was modified and supplemented. The matter units in the 3rd-6th grade science digital textbooks were analyzed by dividing them into "body texts" and "inquiries" area. The results revealed that visual-verbal and visual-nonverbal representations were presented the most. Conversely, audial-nonverbal representations were presented at a high frequency only in the body texts, and audial-verbal representations were presented at a low frequency in both the body texts and the inquiries. Regarding the presentation, when verbal and visual-nonverbal representations appeared together, visual-verbal and visual-nonverbal representations were primarily presented together. In some cases where visual-verbal, audial-verbal, and visual-nonverbal representations were presented together, information on visual-verbal and audial-verbal representations was presented redundantly. Audial-nonverbal representations unrelated to contents were presented along with other external representations, and the frequency was particularly high in the body texts. Regarding the contiguity, no visual-verbal and visual-nonverbal representations were presented on different pages, and no audial-verbal representations were presented asynchronously with visual-nonverbal representations. Regarding the interactivity, explanatory feedback and low-level manipulations were mainly presented. Based on the results, implications to improve digital textbooks are discussed from the perspective of multiple representation-based learning.

본 논문에서는 GUI(Graphical User Interface)를 사용하여 사용자가 상호 작용적으로 도형 언어(visual language)의 문법을 기술함으로서 자동으로 공간 파서를 생성하는 공간 파서 생성기 SPG(Spatial falser Generator)의 구현에 대하여 논한다. 본 시스템의 장점은 다음과 같다. (1) 사용자가 도형 언어의 문법을 정의하고 실제로 파싱하고 싶은 도형 언어를 입력하는데 사용되는 도형 에디터를 가지고 있다. (2) 사용자가 도형을 이용하여 대략적인 문법을 자동으로 생성한 뒤, 수정하여 최종적인 문법을 정의하도록 한다. (3) 제약 해소기(Constraint solver)를 가지고 있어서 파싱된 도형 언어들이 그 생성 규칙에 쓰여져 있는 제약을 유지한다.

The study aimed to identify the differences in language development according to childcare type and child age. Specifically, the study aimed to confirm the difference in the language development between children whose language interactions with their parents are made normally and children whose language interactions with their parents are blocked. With this aim, the study conducted a language development test aimed at a total of 248 children consisting of 146 children raised by their parents and 102 children raised by their grandparents from among children at the age of 3 and of 4. The results obtained from the study include the following. First, the receptive language of children raised by their parents was found to be higher than that of children raised by their grandparents. Second, the expressive language of children raised by their parents was discovered to be higher than the expressive language of children raised by their grandparents. Third, the language development of children raised by their parents was shown to be higher than that of children raised by their grandparents.

복식은 자연환경을 포함한 각 시대의 정치ㆍ경제ㆍ문화ㆍ종교적 요인과 상호 작용하여 구체적으로 표현되어 왔다. 그 시대의 문화를 표현하고, 시각적 혹은 비언어적(non- language) 상징으로, 즉 복식 그 자체로서 언어의 전달과 상징성을 표현함을 의미한다. 따라서 복식은 지각되는 상황을 규정하는데 도움을 주기 때문에 의복상징이 나타내는 의미를 이해하는 것은 중요하다.(중략)

This study investigated the effect of cooperative learning on the middle school students’ conceptual change of atmospheric and water cycle and also examined the verbal interaction patterns in a cooperative group. The study also analyzed the relationship between the verbal interaction and students’ conceptual change in the cooperative learning situation. Two classes from a middle school were selected as an experimental group (cooperative learning group, n = 37) and a control group (traditional learning group, n = 37), respectively. The experimental group was taught by STAD cooperative learning model and received collaborative skill training. The results of the study can be summarized as follows: first, there were no significant differences in conceptual change between the two groups. As for the middle-achieving students on the pretest, however, the score of the cooperative learning group was significantly higher than that of the traditional learning group. Secondly, verbal interaction in the cooperative learning situation mainly happened among high- and middle achieving students. In addition, the students who were successful in undergoing conceptual change had more frequent verbal interactions than the students who were not. The study suggests that it is more important to interact between a teacher and students than to interact between the students and students in order to correct students’ misconception.

This study analyzed the uses of external representations presented in the matter units of the 7th-grade science digital textbooks developed under the 2015 revised national curriculum. The level, form, presentation, and interactivity of external representations presented in 5 types of digital textbooks were analyzed. As for the level, the macroscopic level of representations was mainly presented. The macroscopic level and microscopic level of representations were presented together in the particle description. As for the form, visual-verbal and visual-nonverbal representations were usually presented across the board. Very few audial-verbal and audial-nonverbal representations were presented. Visual-verbal and audial-verbal representations were mostly presented in formal form, and visual-nonverbal representations were mostly presented in illustration without movement. The presentation of representations was analyzed in three aspects. First, visual-verbal and visual-nonverbal representations were mainly presented together and none of audial-verbal and visual-nonverbal representations were presented together. When the representations of the audial-verbal, visual-nonverbal, and visual-verbal were presented together, some of the information presented in audial-verbal representations was repeatedly presented in the visual-verbal representations. Second, audial-nonverbal representations not related to learning content were presented along with other representations. Third, there were few cases of arranging visual-verbal and visual-nonverbal representations on the next pages. Audialverbal and visual-nonverbal representations were always presented synchronized. As for the interactivity, the manipulation level was mainly presented in the main area, and the feedback level was mainly presented in the activity area. The adaptation level and the communication level of interactivity were presented very few. Based on the results, the implications for the direction of constructing digital textbooks were discussed.

Verbal communication has limits in the interaction between robot and man, and therefore nonverbal communication is required for realizing smoother and more efficient communication and even the emotional expression of the robot. This study derived 7 pieces of nonverbal information based on shopping behavior using the robot designed to support shopping, selected facial expression as the element of the nonverbal information derived, and coded face components through 2D analysis. Also, this study analyzed the significance of the expression of nonverbal information using 3D animation that combines the codes of face components. The analysis showed that the proposed expression method for nonverbal information manifested high level of significance, suggesting the potential of this study as the base line data for the research on nonverbal information. However, the case of 'embarrassment' showed limits in applying the coded face components to shape and requires more systematic studies.

From a social constructivists' perspective, knowledge is not transmitted by language but it is constructed by social interactions with others. That is, it is viewed in social constructivism that learning is a process in which knowledge is constructed by communicative interactions with more capable others. In this vein, a class might be analyzed and characterized in terms of interactional patterns of teacher-student and student-student in class. For this, a primary math class was selected and observed and it was analyzed by the Flanders category system to investigate the effects of the math teaching based on verbal interactions on the learning of math. The class was taught in a teacher-centered and direct way but in the class math knowledge was taught through univocal communications in the form of question-answer. The results of this study appeared to suggest that verbal interactional patterns should take place frequently in math teaching in the sequence of a teacher's questions$\to$students' extensive responses $\to$ positive feedback for the students' responses by the teacher $\to$ the acceptance of the students' responses $\to$ the teacher's explanation or students' questions. In other words, math might be taught more effectively through the verbal discourse patterns proposed in this study.
