This study is intended to analyze flipped classroom learning activities, which have recently been spotlighted as a learner-centered teaching method in universities, from the perspective of cultural and historical activity theory. A survey and some participation observations were conducted with one professor and the students who participated in Educational Methods and Technology courses at A university. The components of the flipped classroom learning activities were analyzed based on the model of the activity system, and contradictions that appeared in the interactions between components were analyzed. Four implications were proposed for a more advanced flipped classroom learning activity system: the professor's and the learners' true identity recognition and role performance, strengthening the organic link between online and offline activities, support for alleviating the burden of teaching and learning preparation, and readjusting the system to support its smooth operation.

인터넷에서 멀티미디어 응용들이 증가함에 따라 서비스 품질(QoS: Quality of Service)을 보장해 줄 수 있는 여러 가지 방안이 제안되어 왔는데, 일반적으로 이들 방안은 확장성과 종단간 QoS 보장 간에 상호 모순이 발생하는 경향을 가지고 있다. 본 논문에서는 이와 같은 상호 모순을 피할 수 있는 QoS 지원 방안으로서 DQSP(Dynamic QoS Support Protocol)를 제안한다. DQSP는 도메인 내에서의 자원 예약과 연결 수락 제어 메커니즘을 정의한다. DQSP는 링크 자원을 각 에지 라우터로부터의 트래픽 클래스별로 동적으로 할당하고 에지 라이투가 자신에게 할당된 링크 자원에 관한 정보를 유지하도록 한다. DQSP는 목적지로의 연결 수락 제어를 위한 QoS 신호 프로토콜이 필요 없이 에지 라우터에서 매 사용자 플로우별로 직접적으로 연결 수락 결정을 내리므로 확장성 문제 및 코어 라우터의 복잡한 기능 요구 사항 문제를 해결한다. 또한 UQSP는 에지 라우터가 트래픽 부하에 따라 자신에게 할당되어 있는 자원을 반납하거나 추가적인 자원을 제공받을 수 있도록 해 자원 오버 프로비져닝으로 인해 발생할 수 있는 비효율적인 자원 활용 문제를 해결한다. 또한 DQSP는 경로 재계산을 수행하여 라우팅을 조정해 나감으로써 효율적일 네트워크 자원 활용이 가능하다. 시뮬레이션을 통하여 DQSP와 기존의 자원 할당 및 공유 방식들을 비교한 결과 DQSP가 시그널링과 상태 정보 유지를 위한 오버헤드 면에서 기존의 종단간 QoS 보장을 제공하는 구조인 IntServ에서와 같은 확장성 문제를 발생시키지 않으면서도 효율적으로 네트워크 자원을 활용할 수 있음을 확인할 수 있었다.재 상용화 되어있는 Bellcore 의 S/KEY 시스템과의 비교를 수행하였다. 분석에서는 제품의 효율성뿐만 아니라 보안성을 중요하게 생각하였으며, 앞으로 보안 관련 소프트웨어 개발에 사용될 수 있는 도구들이 가이드 라인에 대한 정보를 제공한다.용할 수 있는지 세부 설계를 제시한다.다.으로서 hemicellulose구조가 polyuronic acid의 형태인 것으로 사료된다. 추출획분의 구성단당은 여러 곡물연구의 보고와 유사하게 glucose, arabinose, xylose 함량이 대체로 높게 나타났다. 점미가 수가용성분에서 goucose대비 용출함량이 고르게 나타나는 경향을 보였고 흑미는 알칼리가용분에서 glucose가 상당량(0.68%) 포함되고 있음을 보여주었고 arabinose(0.68%), xylose(0.05%)도 다른 종류에 비해서 다량 함유한 것으로 나타났다. 흑미는 총식이섬유 함량이 높고 pectic substances, hemicellulose, uronic acid 함량이 높아서 콜레스테롤 저하 등의 효과가 기대되며 고섬유식품으로서 조리 특성 연구가 필요한 것으로 사료된다.리하였다. 얻어진 소견(所見)은 다음과 같았다. 1. 모년령(母年齡), 임신회수(姙娠回數), 임신기간(姙娠其間), 출산시체중등(出産時體重等)의 제요인(諸要因)은 주산기사망(周産基死亡)에 대(對)하여 통계적(統計的)으로 유의(有意)한 영향을 미치고 있어 $25{\sim}29$세(歲)의 연령군에서, 2번째 임신과 2번째의 출산에서 그리고 만삭의 임신 기간에, 출산시체중(出産時體重) $3.50{\sim}3.99kg$사이의 아이에서 그 주산기사망률(周産基死亡率)이 각각

Do animals have a mind? Our understanding about whether animals have minds depends on our relationship with animals, as we cannot determine animals' actual minds. These two studies presented here thus examined the meat paradox, that is, an inconsistency between love for animals and the act of enjoying eating meat in the context of mind perception. Study 1 examined whether mind perceptions toward various animals are classified on the basis of experience-related capacities, such as feeling pain, and agency-related capacities, such as having self-control. In Study 2, mind perceptions toward cows and sexually objectified women were classified on the basis of food condition and non-food condition. In the food condition (experimental condition), cows were portrayed as products for meat consumption, whereas in the control condition, they were described as animals living on a farm, eating grass. The results of Study 2 demonstrated revealed that mind perception was positively associated with how morally incorrect it was to eat animals. Study 2 thus demonstrated that the scores of mind perception toward cows and sexually objectified women in the experimental condition were significantly lower than those in the control condition. These reduced mind attribution in the experimental condition implied that people may be motivated to reduce cognitive dissonance between their attitudes toward animals, such as loving them, and their behaviors, such as, eating meat. In addition, these results suggest that objectification toward animals may impact the objectification and mind perception toward human beings as well. These findings highlight the role of dissonance reduction in the meat paradox and objectification theory so as to understand basic psychological processes involved while making moral choices in everyday life.

By analyzing the characteristics and meaning of dystopia in Korean juvenile science fiction, this study aims to search for the principles of juvenile literature responding to the contradictions of scientific technologism in collusion with state capitalism, and to consider its limitations and significance. This study focuses on the juvenile science fiction in which children or teenagers fight against system dystopia functioning as a setting of the story. System dystopia consists of 'fake utopia' and 'concentration camps' holding those excluded from this 'fake utopia'. Young people whose right to life are violated under the system dystopia escape from concentration camps and fight against political power. We don't have many novels that have focused on environmental dystopia, but a nomadic subject is found in works set on Earth after environmental pollution or nuclear explosion. In short, juvenile dystopia science fiction deepens the contradictions of the hierarchical society based on scientific technologism, criticizing the repressive, material-oriented and differential educational realities of our society. They hope that children or teenagers will act as a resistance that sees through the deception and hypocrisy of the social system. These works are significant in that they expose the biopolitics strategy of political power in collusion with industrial capitalism and induce us to reflect on it. However, it seems to be the limit of humanism to equate human life with nature and to warn of dangers of technology, machinery, and material civilization as the counterpart. This paper has the significance of taking a general survey of juvenile dystopia science fiction since the 2000s, and revealing the writers' perception of scientific technologism and its limitations.

Reflection in teacher education is one reform effort that has taken hold in many teacher preparation programs. However, how to define it and how to foster it in a teacher's education are problematic issues. In this study, on the basis of literature review, science teachers' reflective thinking is defined as a process of thinking that deliberates on alternatives to solve conflict between one's previous knowledge/belief/practice and internal/external factors in science teaching context. Based on this definition, three types of science teachers' reflective thinking (i.e. technical reflection, professional reflection and critical reflection) were proposed. In addition, a framework of classifying the reflective thinking's types was also developed. To investigate science teachers' reflective thinking, two pre-service science teachers who majored in physics education participated in this study. The participants presented the monthly report on reflective practice, pre/post questionnaire, and education practicum journals. Individual interviews with them were conducted before and after their teaching activities. From the analysis of the data, it was possible to categorize the reflective thinking of the participants into three types. The major type of their reflective thinking was the technical reflection. However, it was difficult to find examples of the critical reflection.

Creativity is always important in science gifted education. There are many research results about enhancing the creativity. One of the ways of enhancing students scientific' creativity is to let them think and research like scientists so that they can follow how scientists find problems and solve them. So in this study, scientific creative elements were extracted from the Pauling's detailed examples of research process by using many documents. Abductive reasoning, paradox, changing the perspective, modeling, simplifying, converging thinking, diverging thinking, and metaphorical thinking are thinking methods that were extracted from the Pauling's research process. Repeated experiment, co-experiment, using both theories and experiments, and social obligation as a scientist are research methods. Scientific creative elements that were extracted suggest some direction that have more scientific creativity, more ability to find problems, and more ability to form theories in science education or in science gifted education.

This paper conceptualizes the two-faced platform based on interface studies and two-sided market theory to critically analyze today's information technology culture such as the Internet. With this conceptual framework, the Internet can be investigated to have two faces, in which the square of user's openness, sharing, and participation is unfold on the front face, whereas the market of tracking, surveillance, and control of user's activities is formed on the other face. The two faces contradictorily coexist, resulting in technological and cultural dynamics on the Internet. Therefore, the Internet today as a two-faced platform can be described as a square-market interface. By analyzing on transformation of the web architecture, shift of informational commodity from content to data, and web bugs' user tracking across two faces, it examines how the world wide web itself can function as a two-faced platform. Lastly, implications and further works are suggested to improve the two-faced platform as a conceptual framework and to deeply analyze broader information technology culture based on it.

After the war, the circle literature movement took place in Japan around the 1950s. The subjects of the national movement, the Korean-Japanese, have produced and expanded their political rights and claims through circles and organs in conjunction with the literary movement. However, the results of analyzing the exchanges and conflicts between the political subjects of the Korean national movement and the literary circle movement as a concrete case to date are still insignificant. After liberation, the endless worries and confrontations to the post-colonialization of literary Koreans in Japan were analyzed as 'community with Republic of Korea and Japan', 'topic and creative language', and as 'conflict with Korean association in japan'. The process leading to dissolution was analyzed. The spirit of the era of Koreans in Japan in the 1950s identified in this paper is expected to suggest a new direction for the starting point of study of the humanities in Japan.
