The purpose of this study is to reveal the causal relationship between the demographic characteristics of international students living in Korea and the effect of Korean language level on safety awareness. It was confirmed that there was a significant difference in all areas such as life safety awareness, fire safety awareness, and disaster safety awareness depending on the area of residence. The results to analyze the effect of Korean language expression and comprehension ability on safety consciousness are as follows. First, it was found that Korean expression ability had a positive (+) effect on life safety awareness but did not have a significant effect. Comprehension ability had a negative (-) effect on life safety awareness but did not have a significant effect. Second, it was found that Korean expression ability had a significant effect on fire safety awareness and had a positive (+) influence relationship. Finally, it was found that the Korean language expression ability had a significant effect on disaster safety awareness and had a positive (+) influence relationship. It is necessary to strengthen the awareness of safety for international students while staying and living in Korea, and when teaching Korean, Korean language comprehension education on safety-related topics as well as daily Korean must be strengthened.

Mathematical communication competency, one of the six mathematical competencies emphasized in the latest mathematics curriculum, plays an important role both as a means and as a goal for students to learn mathematics. Therefore, it is meaningful to find instructional methods to improve students' mathematical communication competency and analyze their communication competency in detail. Given this background, this study analyzed 64 sixth graders' mathematical communication competency after they participated in the lessons of fraction division emphasizing mathematical communication. A written assessment for this study was developed with a focus on the four sub-elements of mathematical communication (i.e., understanding mathematical representations, developing and transforming mathematical representations, representing one's ideas, and understanding others' ideas). The results of this study showed that students could understand and represent the principle of fraction division in various mathematical representations. The students were more proficient in representing their ideas with mathematical expressions and solving them than doing with visual models. They could use appropriate mathematical terms and symbols in representing their ideas and understanding others' ideas. This paper closes with some implications on how to foster students' mathematical communication competency while teaching elementary mathematics.

Despite the importance and necessity of functional thinking in a primary school there has been lack of research in this area, specifically regarding young children. Given this, this study analyzed how students aged from 7 to 9 would figure out and represent the co-variational relationships in context-driven tasks. Semi-clinical interviews were conducted with a total of 12 students. Interview tasks included three types of functions: (a) y=x, (b) y=x+1, and (c) y=x+x. The results of this study showed that most students were able to figure out co-variational relationships in diverse ways. Some factors such as types of function or characteristics of tasks had an impact on how students recognized the relationships. The students also could represent the relationship in diverse ways such as gesture, picture, natural language, and variables. They usually used natural language, but had a trouble using variables when representing the relation between co-varying quantities. Based on these results, this study provides implications on how to foster functional thinking ability at the elementary school.

As evolution of multimedia technology brings changes to industries concerned with design, new education program is needed to cultivate designers with abilities which are adapted to changed circumstance. This paper is purposed to show guideline to set up a fundamental course for multimedia design in which students know what are new presentation modes and learn how to use them, Multimedia design call for abilities of organizing information, representing, and implementing interactivity. Among them, fundamental course considers representing information as central subject. And it also contains lessons which are relative to proceeding courses. It should have students to experience creative composition and various expressions, and study cognitive or aesthetic effects of them. All activities are based on the understanding about presentation factors and principles. Basic course's lessons are composed by two main subjects, which are essential expression and matters relative to organization and interactivity. Described in detail, lessons are divided into three phases. First phase is combining presentation factors for affective effects, second is delivering message of various knowledges and third is forming simple interaction.

The purpose of this study is to investigate the differences among mother's feeling expression, children's self-regulation, and children's peer competency by socio-demographic background and provide a basic material to develop the parents' education for mother's promosing emotional environment to help development of children by understanding the correlation among mother's feeling expression children's self-regulation, and children's peer competency. The research objects were 361 of 4 to 6-year-old children and their mothers. The tool adapted by Woo Sookyong(2002) was used for Mother's emotional expressivity, and the tool of Lee Jeongran(2003) for the of self regulation and the tool of park Joohee and Lee Eunhae for the children's peer competency. Data analysis was performed with population, percentage, t-test, Cronbach $\alpha$, F-test, and co-relation of LSD posteriori test. The summary of this study are as follows; First, the more negative expressivity was shown as mother's academic career was higher and the more positive one was appeared as family income was greater according to the background of socio-demography. Female children showed the higher self-regulation, and the self-decision and action control were greater as their age was higher. Children's peer competency was higher as they were social and friendly personality. Second, there was the strong relationship among the mother's feeling expressivity, children's self-regulation and peer competency one. Mother's positive expressivity had the relationship with children's self-regulation and peer competency one while weak expressivity had it with self-decision, regulation and children's peer competency. But the strong negative heartstrings' expressivity was an improper co-relation with action control and no relation with similar age competent ability. A definitive relation existed between all low level area except the emotion of self-regulation and children's peer competency. Form the above study, it was Known that there was the relationship among the mother's feeling expressivity, children's self-regulation and peer competency. In particular, there was strong relationship between positive and weak positive expressivity, and children's self-regulation and peer competency. These results could be reflected to parents' heartstrings education by knowing the impact of a positive emotional expressivity and weak-negative one.

유비쿼터스 컴퓨팅 환경에서 서비스를 제공함에 있어 지능적인 수행 능력은 사용자의 만족도를 높여주는 핵심 요소이다. 시스템의 지능을 부여하기 위해서는 지식을 관리, 처리, 활용하는 기능이 필요한데, 이들 기능은 그 지식이 어떻게 표현되어 있는지에 큰 영향을 받는다. 일차 술어 논리 기반 지식 표현 방법은 폭넓은 표현 범위와 유연한 지식 정의, 추론 방법으로 선호되고 있지만, 복잡한 계산 비용을 갖고 있기 때문에, 전문적인 지식 처리 시스템이 아닌 경우, 불필요한 계산 비용이 소요된다. Description Logic은 Frame기반 지식 표현 방식으로 일차 술어 논리를 사용하는 것보다 지식을 표현할 수 있는 범위는 제한적이지만, 빠른 추론 결과를 보장해 준다. 유비쿼터스 컴퓨팅 환경에서는 분산된 다양한 오브젝트들이 협력과정을 통해 사용자에게 지능적인 서비스를 제공하게 되고, 이들 개별적인 오브젝트들은 저사양의 계산능력을 갖고 있다고 가정된다. 그러므로, 저사양의 컴퓨팅 오브젝트들을 조합하여 지능적인 서비스를 성공적으로 제공하기 위해서, 각각의 오브젝트들은 제한된 지식을 효과적으로 관리할 수 있는 방법이 필요하다. 이를 위해 본 논문에서는 Frame 기반의 Description Logic을 기반으로 SUNHI의 표현 범위를 가진 인식론적 온톨로지 표현 언어를 제안하고, SUNHI의 표현 범위의 효율성을 증명하고자 한다.

The purpose of this research is to investigate the usage of voice scripting for speech characterization. The ultimate goal of acting is for an actor to create one's character both in physical and vocal sense, and to present them on stage. Toward this goal, actors train themselves with various methods and techniques as well as character analysis. Most of their efforts are put into for better physical and vocal expression. The vocal characterization on stage is heavily governed by the proper speech based on the effective respiration and voice. This paper provides the way of how to use sound scoring for effective vocal characterization on stage.
