빈곤과 질병은 인류의 역사만큼 오래된 전통(?)이며 어떻게 보면 앞ㆍ뒷면과 같아서 빈곤의 악순환(vicious cye of poverty)이라는 연결고리 속에서 긴밀하게 연결되어 있다. 이러한 사실은 의료문제의 해결이 빈곤문제의 해결을 위해 기여할 수도 있고, 의료 문제의 악화가 빈곤문제의 심화를 초래할 수도 ......

Inquiry has been emphasized in science classrooms, but the problems shown in the inquiry are somewhat different with ones that students usually meet and experience in everyday life. The purpose of this study is to investigate how attitudes toward the task and thinking skills affect students' problem solving process, especially, the way of creating a problem space and elaborating problem solving strategies when they have little schema. The difference in students' problem solving strategies of Lego Robotics class, one of the summer programs for $4^{th}-6^{th}$ grade gifted students, which is new to them, was investigated. The results are as follows: (1) The difference in attitudes toward the task, or selection and identification of the missions, and the perception of operators, affected creating a different problem space. (2) Different level of thinking skills, or analytical and flexible thinking, efficient elaborative skill, and application of schema affected a different level of elaboration of the problem space and resulted in asuccess rate of problem solving. (3) Different initial problem space resulted in different problem solving strategies. But without thinking skills, students could not elaborate problem solving strategies efficiently. Several instructional recommendations to promote scientific inquiry were suggested based on the results.

Students need to have opportunities to share their ideas with peers by taking part in the conversation voluntarily that is, by persuading others and reflecting the consequences. Recognizing the importance of this point, this study intended to examine students' argumentation occurring in the process of performing tasks in the math classroom. Also, it tried to explore the types of the argument that students used in the classroom and the reason why they employed them with a focus on 'rebuttal', which is one of the six elements of the argument scheme such as claim, data, warrent, backing, qualifiers, and rebuttal. The analysis of argumentation is based on the five argumentation schemes suggested by Verheij(2005). The experimental class was conducted twice a week with four participants who are third grade middle school students. In the argumentation class students were promoted to address two different kinds of geometrical tasks. After the second session of class, the researcher conducted the semi-structured interview. Accordingly, this study contributes to the existing research by making students to have concrete and active argumentation while obtaining the sound understanding of the argumentation.

The objective of this study is to explore the meaning generated through discourse in three different types of 1st-grade middle school textbooks in Korea and CMP textbook in the United States, specifically focusing on histograms. Through a discursive perspective, the study aims to analyze the characteristics of questioning within the stages of statistical problem-solving found in histogram tasks. The findings highlight several significant points. Firstly, variations exist in the definitions of histograms between Korean and US CMP textbooks. Secondly, diverse discursive structures contribute to the interpretation and understanding of histograms in textbooks. Thirdly, limitations are observed in the stages of statistical problem-solving reflected in histogram tasks. Lastly, distinctions are identified in the types of questioning employed in histogram tasks between Korean and US CMP textbooks. Building on these insights, the study suggests concrete ideas for enhancing the process of defining histograms and refining the questioning in histogram tasks.

As the computer and the communication technology are an unity, the collaborative learning based on constructivism is emphasized more than learning by forming external representation. Especially, online has characteristics not only to facilitate collaborative activities but to make students collaborators. In online collaborative learning, learning task is an integrated element in course design and an important portion deciding learning design, learning environment and learning process. Thus this study explored collaborative learning model according to the learning task type.

90년대를 맞아 정유업계는 해결해야 할 많은 과제를 안고 있다. 석유수요의 증가에 따른 안정공급기반의 확충과 석유수요구조의 경질화ㆍ가스화ㆍ저유황화에 따른 시설고도화가 당면과제로 등장하고 있다. 그러나 정유산업 허용이익의 절대규모부족과 적정이윤미현실은 성장발전의 제약요인이 되고 있다. 또 현행유가관리제도도 개선ㆍ보완 내지 폐지되어야 한다는 의견이 높다. 이에 석유협회에서는 설문을 통해 각계의 의견을 들어본다. <편집자 주>

기업에서 정보보호의 역할이 중요해 지면서 이를 책임지는 CSO제도가 점차 도입되어가고 있다. 특히, 최근 국내 정부기관에서의 정보보호를 위한 종합대책을 발표하면서 중앙행정기관 및 지자체와 일정 규모 이상의 기업들에게 CSO 제도 도입을 의무화 하고 있다. 이런 상황에서 CSO의 역할과 변화추세, 그리과 해결해야 할 과제를 살펴보는 것은 매우 시의 적절하다고 하겠다.
