수학의 내용을 학생에게 지도할 때 기계적인 계산법칙을 가르치는 것보다 개념을 이해할 수 있도록 돕는 것은 교사의 중요한 역할이다. 그 동안 연구를 통해 정수를 지도하기 위한 모델들은 꽤 많이 알려져 왔으나 이 모델들을 학생에게 직접 적용하였을 때 일어나는 현상을 파악한 연구는 그리 많지 않다. 따라서 본 연구는 상위, 중위권 초등학교 5학년을 대상으로 EIS이론에 바탕을 둔 정수의 모델을 통해 학생들이 정수의 개념을 어떻게 형성하고 그 과정에서 어떤 오류를 나타내는지, 또 무엇을 가장 어려워하는지 등 그 학습과정을 조사하였다.

표층플랑크톤 생물군을 통한 물질순환을 이해하기 위하여 많은 연구자들이 식물플랑크톤, 동물플랑크톤, 영양염 사이의 물질순환을 간단한 미분방정식으로 표현한 생태계모델을 이용해 왔다. 그 중에서도 특히, Fasham(1995)은 북대서양과 북태평양의 식물플랑크톤의 계절변화를 설명하기 위하여 간단하지만 표층 혼합층내 물질순환과정의 본질을 잘 표현한 혼합층모델을 작성했다. (중략)

생명 현상을 시스템적으로 이해하기 위해서는 현상에 대한 수학적 모델링이 필수적이다. 여러 가지 수학적 모델 가운데 상미분 방정식(ODE) 모델은 여러 가지 생화학 반응을 모델링 하는데 널리 사용되고 있다. 본 논문에서는 신호전달 경로에 B형 간염 바이러스가 미치는 영향을 ODE로 모델링하고, 이를 시뮬레이션 한 결과를 보인다. 또한, ODE모델을 설계하는데 있어 보다 유연하고 확장 가능한 새로운 표현 방식을 제안한다.

As a de facto standard for system modeling, UML diagrams have been widely used in the industry. Of these, the class diagram is useful to visualize the classes and their relationships and thus directly influences the forward and reverse processes of system modeling and development. Many earlier studies have attempted to examine as to what impact the layout and complexity of the class diagram would have on the comprehension of system modeling. However, their findings have been equivocal and it is not easy to understand the effects of diagram layout. Accordingly this research relied on the guidelines of diagram layout suggested in the earlier studies and designed a 2 (layout) x 2 (complexity) factorial design to examine their impact on diagram comprehension. 47 subjects were participated in the experiment where class diagrams were provided differently in their layout and complexity. We found that a good layout was significantly more effective than the bad. Furthermore the results were significantly persistent in the complex group than the simple. However, there was no interaction effect between layout and complexity of the diagram.

Although tourism has been quite popular as development strategy, the outcomes may vary dependent upon managing stakeholders involved. Thus, stakeholder management has been the subject of growing research interests recently. Collaboration theory was suggested as an alternative to this question; however, collaboration theory may provide potential benefits, it lacks in consideration into stakeholder power relations. The purpose of this paper is two foleded. One is to examine critically collaboration theory in the context of tourism development, and address the necessity of stakeholder analysis framework, and the other is to provide the framework. This paper argues that careful analysis of stakeholders from diverse perspectives should be done in advance, and presents stakeholder analysis framework which consists of six analysis indicators: interest, perspective, power base(resource), involvement, influence, and legitimacy. The framework consists of three stages: (1) identifying stakeholder, (2) assessing stakeholder, and (3) establishing strategies. It is argued that the framework in this paper can be useful to analyze stakeholders and to set up strategy for more collaborative tourism development.

As the Korean market is becoming increasingly diverse, it is imperative that marketers targeting the Korean market understand the consumers with various racial and cultural backgrounds. The current study investigated the effects of the endorser race (White vs. Black) on the attitudes toward the ad and brand while varying the experimental context (private vs. public) and product type (high involvement-rational vs. low involvement-emotional) with White participants. Impression management was included as a covariate. The results showed that when the endorser was White and the product was an automobile, participants indicated more positive attitudes toward the ad in the private context than in the public context. When the endorser was Black, the context had no significant effects on the attitudes. The implications of these findings for the Korean market are discussed.

This paper explains that socio-cultural contexts affect the transition in scholarly communication. Observing the process of introducing the open access model to the field of medicine in Korea, this paper found that the first, associations of medical societies considered a quality control system very important in the construction of an open access based fulltext DB, the second, there was an medical journal DB with a quality control procedure, and the third, many medical societies provided their journals fulltext to the public on their homepages. Consequently, this paper found that these factors had an effect on the process of transition in scholarly communication in the field of medicine in Korea.

Introduction : Animal studies cannot be applied directly to Occupational Therapy(OT) intervention protocol. However, animal models still provide essential evidences and knowledge to improve OT practice and to develop OT theories as well as human studies do. The purpose of this scholarly paper is to explore the potential of animal models to inform OT theory and practice particularly as it relates to neuroscience. Body : The animal models provide related knowledge for a better understanding of the mechanism of diseases and related neural networks. Based on this knowledge, researchers can test their hypothesis of neural disease. In addition, accumulated animal studies contribute to introduce the new approaches to human diseases and to improve the effectiveness of treatment. Conclusions : Animal models of neurological disease are critical and have the potential to improve OT practice and theory in many ways. Therefore, OT researchers need to pay more attention to animal models in addition human studies.
