In this study, students' understanding of the analogies used for chemical concepts in science textbooks, misconceptions induced by the analogy, and the factors affecting conceptual understanding were investigated. In addition to the tests of field independency and logical thinking ability, tests of students' understanding of concepts and analogies on three states of matter, pressure-volume relation, molecular motion, and changing state depending upon energy were administered. The results revealed that half of the subjects understood the analogies differently from the textbook writers' intention and that students' conceptual understanding was significantly correlated with the degree of understanding on corresponding analogies, field independency, logical thinking ability, and prior achievement of science. The results of analyzing the direct and indirect effects of each variable on conceptual understanding showed that the direct effect of prior achievement was significant and that field independency and logical thinking ability had indirect effects through understanding of analogies and prior achievement of science. The limitations and implications of using analogies in science education were discussed on the basis of the results.

소위 '무한경쟁'과 '경영혁명'이라는 시대조류에 따라 모든 기업들이 너나 할 것 없이 조직혁신의 대열에 합류하면서 '인사파경', '신인사제도', '학습조직'등 다양한 개념과 제도가 기업현장에 등장하고 있다. 이와 더불어 '구성원의 욕 구'와 '조직의 생존논리' 사이에 형성되어 있던 힘의 균형이 점차 조직의 생 존논리 쪽으로 기울어지면서, 그간 기업의 발전을 위해 전력해 왔던 중간관 리자들이 심리적 압박감과 함께 점차 여과되어지는 추세에 있다. 본 논문은 이러한 현상에 주목하면서 'K'은행의 관리자를 대상으로 한 설문조사를 토대 로 바람직한 중고령자 대책의 방향을 살펴보려는데 그 목적을 두고 있다.

본 논문은 기존의 유선환경에서의 서비스 환경을 이동 환경에서도 지원하기 위한 분산 구조를 다루고 있다. 이를 위하여 이동 단말기를 논리적으로 대신하는 이동 AP의 위치를 추적하는 추적 AP를 두어 기존의 응용 환경에서 수행되던 응용 프로그램들을 무선이동 환경에서도 수용할 수 있도록 하였다. 이동 단말기의 위치 변경에 따른 이동 AP, 추적 AP 사이에서 발생되는 핸드오프처리 알고리즘이 소개되었으며, 이 알고리즘은 패킷 손실이나 순서의 변경과 같은 흐름제어 기능을 포함하고 있다. 또한 무선 환경에서 발생 가능한 핸드오프와 소프트 핸드오프를 함께 고려하였다. 시뮬레이션의 결과는 핸드오프 과정에서의 추가 지연 시간에 대한 내용을 다루고 있다.

In this paper we proposed and implemented an incident detection model which combines fuzzy algorithm and traffic pattern in order to enhance the efficiency of incident detection for the highways with lamps. Most of the existing algorithms dealt with highways without lamps and can not be used for detecting incidents in the highways with lamps. The data used for model building are traffic volume, occupancy, and speed data. They have been collected by a loop sensor at 5 minutes interval at a point in the Internal Circular Highway of Seoul for the period of 3 months. In this model, the three parameters collected by sensor were fuzzified and combined with the daily traffic pattern of the link. The test of efficiency of the propsed model was performed by comparing the result of proposed model with traditional APID algorithm and fuzzy algorithm without the pattern data respectively. The result showed significant amount of improvement in reducing the false incident detection rate by 18%.

Technology has many potential uses and changes by social context surrounding it. Therefore political implications are reflected in the internal logical system of articraft, technology. This explanation is ale to apply to the regulation technology of Internet. The empowerment of information is changeable according as which regulation technology is adopted. This paper explores the structure, principle and its social implication of regulation technology of Internet, which coincides with user empowerment of information as a case of ICRS(Internet Content Rating System).

Human being has attempted to solve the problem of imperfect knowledge for a long time. In 1982 Pawlak proposed the rough set theory to manipulate the problem in the area of artificial intelligence. The rough set theory has two interesting properties: one is that a rough set is considered as distinct sets according to distinct knowledge bases, and the other is that distinct rough sets are considered as one same set in a certain knowledge base. This leads to a significant philosophical interpretation: a concept (or an event) may be understood as different ones from different perspectives, while different concepts (or events) may be understood as a same one in a certain perspective. This paper claims that such properties of rough set theory produce a mathematical model to support critical realism and theory ladenness of observation in the philosophy of science.

This paper deals with the question whether the metaphysical dialetheism is a persuasive view or not. That is, the purpose of this paper is to criticize the metaphysical dialetheism by answering three questions, whether the dialetheism is compatible with the correspondence theory of truth, whether there is an observable contradiction, finally what the status of LNC is. In conclusion, it is argued that dialetheism is incompatible with the correspondence theory of truth, because it results in trivialism to suppose that two views are compatible. It is also claimed that LNC should be understood as the principle of exclusion which constrains the structure of the world and that the real world is consistent. Therefore, there is no observable contradiction in the world and the metaphysical dialetheism is not persuasive.

In this study, we investigated the characteristics of analogs generated by high school students to explain ionic bonding in the perspectives of the number of analogs, the understanding of mapping, and the source and type of analogs. We also compared the results by students' conceptual understanding, logical thinking ability, and analogical reasoning ability. Participants in this study were 395 11th graders in Seoul. The results of the study showed that the higher the conceptual understanding, the logical thinking ability, and the analogical reasoning ability, the more the students generated the analogs. The understanding of mapping was related to logical thinking ability and analogical reasoning ability. It is noteworthy that the sources of analogs differed only depending on their conceptual understanding of the target concept among the cognitive variables studied. Students who had higher conceptual understanding also generated analogs from more diverse sources. Some types of the generated analogs were related to the cognitive variables. For examples, the students who had higher conceptual understanding and logical thinking ability generated more verbal/pictorial analogs. The types of analogs were not related to cognitive variables in terms of artificiality, abstraction, and systemicity. Educational implications of these findings were discussed.

최근의 영재의 개념은 다중지능, 다양한 재능을 포함하는 복합적인 확장된 개념으로 이해하고 있으며, 이러한 다양한 능력을 키워줄 수 있도록 함으로써 21세기에 걸맞은 인재를 양성하는데 초점을 두고 있다. 이런 측면에서 Gardner의 다중지능 이론은 영재교육에 시사하는 바가 크다. 본 연구에서는 영재의 다중지능 특성을 분석하여 강점과 약점을 파악함으로써 다양한 직업을 선호하는 그들의 능력을 균형적으로 계발해 주고 저마다의 소질과 적성을 키워줄 수 있는 데 관심을 가지려고 한 것이다. 전반적으로 초등수학영재는 개인이해 지능, 논리-수학적 지능, 대인관계 지능이 강하고, 신체-운동적 지능이 약하게 나타났다. 또 직업 선호도에서는 의료인 선택이 가장 많은 바, 수학영재에 대해 논리-수학적 지능 영역에 관한 교육과 아울러 다른 다중지능 특성과 적성에 맞는 교육도 복합적으로 할 수 있는 방안이 마련되어야 할 것이다.
