This study investigated information acquisition from hypertext and the difference of searching behavior between adults and children. In experiment 1. we compared the amount of information acquisition from the hypertext to that of the printed text. The result showed that the performance in printed text was better than in hypertext. However. the performance of experienced (in the internet) participant showed no difference between the hypertext and the printed text. Experiment 2 compared the information-searching behavior of the adults and children in the hypertext environment. The results showed that adults performed the information-searching faster than children, yet there was no difference in the proportion of correct responses of the two groups. However. children who were more experienced in the internet and produced right answers to the 7th level questions in depth performed better and faster than the adults who were not. These results suggest that the experience in the internet is the most important factor in the searching of the wanted information.

현재 대부분 e-Learning에서 이루어지고 있는 교육은 학습(Loaming)이 아닌 단순 훈련(Trainning)만이 이루어지고 있다. e-Learning에서 진정한 학습이 이루어지기 위해서는 학습자의 수준에 맞는 적응적(Adaptive), 적시적(Just-in-Time) 학습이 단편적이 아닌 연속적, 통합적으로 이루어져야 한다. 이를 위해서는 기술적 관점뿐만 아니라, 발견적 학습(heuristic learning)관점에서 학습자원이 기술되고, 컴퓨터(에이전트)가 학습자원의 구성요소인 학습목표(Goal), 학습내용(Content), 학습맥락(Context), 학습구조(Structure), 학습전략(Strategy)의 의미(Semantic)와 관계(Relation)를 이해해 학습자에게 필요한 정보만을 검색, 추론해주고 이를 학습자 수준에 맞게 재가공해 학습자에게 지식(Knowledge)을 적응적(Adaptive), 적시적(Just-in-Time)으로 전달해주는 e-Learning 학습 환경이 필수적이다. 메타데이터(RDF), 온톨로지(Ontology), 에이전트(Agent) 매커니즘의 시멘틱 웹을 e-Learning 환경에 적용함으로써 학습자원의 구성요소의 의미와 관계를 파악해 적응적(Adaptive)으로 지식을 전달해 주어 자기 주도적 학습(Self-directed Loaming)을 실현해 줄 수 있다.

본 연구에서는 산학협력의 관계를 통해 발생하는 장애를 파악하고 이를 극복할 수 있는 요인을 대학행정의 노력과 신뢰에서 찾아본다. 기존 산학협력의 연구에서, 산학간의 관계는 경로의존성에 의해 지속적인 상호작용과 지식의 흡수역량을 키움으로써, 양자간 협력에 대한 누적된 경험과 다양한 채널의 폭을 가진다. 하지만 상호간 인식의 차이와 제도적 장벽과 같은 산학협력의 장애는 필연적으로 발생한다. 이러한 장애를 극복해야만 좀 더 효과적인 성과를 유도하고, 지속적인 산학협력의 관계가 유지될 수 있을 것이다. 연구결과, 대학행정의 노력수준과 산학간의 신뢰가 높을수록 산학협력 장애요인인 상호인식의 차이와 제도적 장벽은 낮아지는 것으로 나타났다. 따라서, 산학협력장애를 극복할 수 있는 이 두 가지 요인의 수준을 높이기 위한 산학연관 주체의 관심과 실행 및 제도적 뒷받침이 뒤따라야 할 것이다.

This paper presents fuzzy Pr/T nets to represent the fuzzy production rules of a knowledge-based system in the level of first-order predicate logic. The fuzzy Pr/T nets are fuzzy extension of the Pr/T nets. Based on the fuzzy Pr/T net, we propose a fuzzy reasoning algorithm. This algorithm is much closer to human intuition and reasoning than other methods because of using the proper belief functions according to fuzzy concepts in fuzzy production rules.

프레임워크는 객체 지향 재사용 방법중의 하나로서 사용되고 있다. 프레임워크는 소스 코드의 재사용뿐만 아니라 지식의 재사용이라는 측면에서 보다 높은 수준의 재사용이다. 여기서 소스코드의 재사용이 객체 지향 중심에서 컴포넌트 기반으로 바뀌어 가는 추세에 맞추어 프레임워크 역시 객체 지향 프레임워크에서 컴포넌트 프레임워크로 바뀌어 가고 있다. 컴포넌트 프레임워크는 객체지향 프레임워크와는 달리 컴포넌트들의 컴포지션에 의한 어플리케이션 개발로서, 컴포넌트간의 연결성을 명세함으로써 프레임워크의 아키텍쳐를 보다 상세하게 표현할 필요가 있다. 본 논문은 이러한 컴포넌트 컴포지션에 필요한 프레임워크의 아키텍쳐 정보를 표현하는 한가지 방법으로서 ADL을 통해 통해 프레임워크의 아키텍쳐를 표현하고, 이 ADL을 다른 프레임워크 보조 도구와 함께 사용하면서 컴포넌트 컴포지션을 보다 용이하게 함으로써, 어플리케이션을 개발하는 것과 보다 높은 수준의 재사용을 가능하게 하고자 한다.

The purpose of this study is to analyze the recent consumption patterns and consumer's perception changes in the Korean beef market and thus to analyze whether there was any structural changes in beef consumption patterns in Korea. This current survey was conducted to examine consumer attitudes toward factors determining beef purchasing and improving distribution system. First, it is vital to cut beef production costs and expand high-quality beef in order to compete with imported beef. Second, it is also important to endeavor to enhance th safety of beef. Also consumers demand more information on the quality of beef. Third, promotion activities are very important to maintain Hanwoo beef market power. Forth, it is important to prevent imported beef from being sold as Hanwoo beef at retailers. Finally, we should pay more attention to maintain beef consumption data.

본 연구는 판매노력을 열심히 일을 하는 것과 효율적으로 일을 하는 것으로 구분하고 판매노력에 대한 감독자의 정보제공과 판매원의 감독참가의 효과를 알아보는데 역점을 두고 수행되었다. 판매원의 감독참가와 감독자의 정보제공은 종업원이 자신들의 목표와 성과 그리고 능력과 활동에 관한 내용을 능동적으로 인지하게 함으로서 종업원의 지식수준을 높아지게 하고, 판매원에게 기대되는 역할을 인지하는 하는 것으로 나타났다. 한편 종업원의 지식수준은 종업이 일을 열심히 하고, 효율적으로 하는 정도에 긍정적인 영향을 미치고 판매원으로 하여금 판매직무에서 본인에게 기대되는 것이 무엇인지, 자신이 해야할 일이 정확히 무엇인지를 인지하게 하는데 긍정적인 영향력이 있음을 알 수 있었다. 그런데 역할명료성이 일을 열심히 하게 하는데 영향을 미치는 것으로 나타났지만 효율적으로 하는 효과는 없는 것으로 나타났고, 오히려 감독통제수단으로서 정보제공이 판매원이 일을 효율적으로 수행하게끔 하는데 유의적인 직접효과가 있음을 발견하였다.

In this study, environmental knowledge and consciousness and eco-friendly behavior related to dietary life of middle school students were examined. Male and female students in Gyeongsan and Daegu Metropolitan City were selected for the study. Total of 490 questionnaires were delivered and collected, and 445 of them were analyzed by using SPSS Win Ver 12.0. Percentages of students who checked' don't know the answer' in 20 environmental knowledge assessment questions were $14.4\~41.8\%$, and those who gave correct answer to these responded to how the answer were $40.1\~93.3\%$. The average score of environmental consciousness was 3.45 and that of eco-friendly dietary behavior was 2.9 out of 5. When dietary behavior was divided by three categories, such as food purchasing, eating. and dish washing, the score of food purchasing behavior was 2.7, those of eating behavior and dish washing behavior were 3.0, 3.1, respectively. In the relationship between environmental knowledge. consciousness. and eco-friendly dietary behavior, there was significant positive correlation between howledge and consciousness, but no significant relation between consciousness and behavior. It showed that environmental knowledge and consciousness didn't always lead to eco-friendly dietary behavior. Therefore, education for practical betlavior must be emphasized even though the knowledge and consciousness education on environment are important.

The purpose of this study was to analyze characteristics of problem solving process with proportional or compensational reasoning of the elementary school students. For this study, 85th grade students were selected and tested with Science Reasoning Task, information processing ability test and proportional and compensational reasoning tasks. This study revealed that students in mid concrete stage could solve the proportionality task and easy compensation task. But, most of the students could not solve difficult compensation task. And as the students got higher score in information processing test, it took them less time to solve the problem. The types of strategy used in solving proportional and compensational problem were categorized as the factor of change, building-up and the cross-product. Most of the students failed in problem solving used incorrect schema knowledge, procedure knowledge and strategy knowledge. Many students tended to use proportionality strategy to solve the difficult compensation task. Result of this study suggested that various task included different structure and the same schema knowledge can be effective for the advancement of students' proportional and compensational reasoning ability.

The purpose of this study is to examine epistemic thinking in middle school students in an argument-based inquiry science class. Participants of the study were 93 9th grade students from four classes of a middle school in a metropolitan city. Observations were made over one semester during which argument-based inquiry lessons on five subjects were conducted. Data was collected from argument-based inquiry activity worksheets and student questionnaires. After analysis of epistemic thinking in the written reflections, students were found to have the highest frequency of epistemic metacognitive skills, followed by epistemic cognition, epistemic metacognitive experience, and epistemic metacognitive knowledge. While investigating the effects of an argument-based inquiry science class on student epistemic thinking and after analysis of the reflections written for the first ABI activity and the fifth ABI activity, we found that all of the sub-elements of epistemic thinking have increased. The rate of growth for epistemic cognition is greatest, followed by epistemic metacognitive knowledge and epistemic metacognitive skills. Assessed for epistemic thinking, the level of epistemic thinking improved over the course of the argument-based inquiry science class. The results of the survey show that students actively participating and being recognized for their active participation in the argument-based inquiry science class are helpful in understanding scientific knowledge. Therefore, an argument-based inquiry science class is a teaching and learning program that allows students to understand and experience the epistemic nature of scientific knowledge and its construction through collaboration and agreement.
