  • 본 발표에서는 베이지안이 생각하는 확률의 개념을 상호교환성(exchangeability)의 가정아래 어떻게 확장되어 해석되는지를 소개하고, 빈도학자들의 접근방법과 비교함으로서 베이지안에서 생각하는 확률이 어떠한 특징을 가지고 있는지를 설명하고자 하였다. 또한 Efron에 의하여 지적된 베이지안의 네 가지 문제점에 대하여 논의하고 특별히 과학적 객관성(scientific objectivism)의 한계점과 이러한 한계점을 베이지안에서 어떻게 해결하고 있는지에 대하여 논의하였다. 일반적으로 과학적 객관성에 대한 한계점은 빈도학자들의 방법론에서도 존재하게 된다. 즉, 연구자가 가설을 설정하고 이에 맞는 실험설계를 하고 유의수준을 설정하고 p값을 이용하여 의사결정을 내리는 모든 단계에서 연구자의 주관성이 들어갈 수밖에 없게 된다는 것이다. 베이지안 방법론에서는 이러한 비객관적인 체계를 인정하고 파악하여 사전확률(prior)에 포함시킴으로서 이를 객관적인 자료인 가능도함수(likelihood function)와 혼합하여 추론이나 의사결정을 진행하게 된다. 마지막으로 베이지안 학자들의 최근 객관적인 사전확률에 대한 다양한 형태의 연구를 소개하는 것으로 발표를 마무리하고자 한다.

  • In this thesis, the cognition of students gifted in science on pseudo science was studied in order to acquire basic data to develop a learning program. As a first step, the difference of cognition on pseudo science between science-gifted students and general students in elementary, middle and high schools was studied. Findings revealed that science-gifted students had more negative thought on pseudo science than general students. In addition, there was no progress in their cognition on pseudo science as entered higher grades. Secondly, the cognition of students in a science high school, three times over a 6-month period, was studied. Through this study, it was found that student concepts of pseudo science was not firm, and it is quite possible to induce students to think logically and rationally with the help of a well-organized learning program. Lastly, the factors that might affect student ideas on pseudo science were researched. Students were affected by media such as television and books and also by personal experience. Therefore, students should be trained to correctly judge information presented in the media as authentic or false. Moreover, they should also be provided chances to look back on positive astrological experiences.

  • The purposes of this study are to investigate elementary students' perception of science classroom through an analysis of students' answer to an open-ended question and to suggest a framework for the analysis of science classroom culture, as the first step to develop an analysis tool for qualitative exploration of science classroom culture. We analyzed 571 responses and developed an analysis framework with six categories (i.e. major factors; power structure of a classroom community; focused domains of the science classroom; student concerns; atmosphere of science classroom; participation form). The details of the six categories can be summarized as follows: (1) major factors were revealed to be practical work, fun, teacher, community and others; (2) the power structure of classroom community was in the order of peer students, teacher, and individual student himself/herself; (3) the focused domains of the science classroom perceived by students were more about affective and behavioral domains than cognitive one; (4) major student concerns were teachers' teaching, having practical work, and the understanding of and the sharing of knowledge and opinions (5) science classroom atmosphere was noisy and pranky but fun and interesting; (6) the students participation forms were to be total participation or voluntary participation or cooperative practice. Through this study, not only suggesting the framework, but we could also get implications for the cultural aspects of science classroom based on the results of data analysis in this study.

'Techno-scientific Way of Thinking' on Women's Technoscientific Practices : From Barad's Agential Realistic Perspectives (여성들의 기술과학 실행에 대한 '기술-과학적 방식의 생각하기': 캐런 바라드의 행위적 실재론을 중심으로)

  • This paper, as an initiative to fertilize analyses on women's technoscientific practices, reviews theoretical discussions and empirical studies in-between feminism and STS, mainly owing its thinking technologies to Karen Barad's Agential Realism. The first part of this paper shows that women's technoscientific practices as research sites are not only fertile grounds between STS and feminism but also conflict areas between constructivist theories and feminist politics. The second part proposes Agential Realism as an way of thinking to deal with 'conflicts' between STS and feminism in analytical levels. Agential Realism provides useful conceptual tools for 'techno-scientific ways of thinking' through the reconceptualization of agency, the displacement of agency by accountability, and the configuration of STS analysis as 'apparatus.' The third part finds three examples of 'techno-scientific ways of thinking' on women's technscientific practices from previous feminist STS works, which suggests how to analyze not only women's technoscientific practices but also diverse practices of science, technology, and medicine as follows: follow 'the invisible', account for 'ontological choreography', and 'care' for what is analyzed.

  • This study examined the effect of intentional thought avoidance(i.e., thought suppression and thought substitution) using "Think and No Think" task. Two syllable words were selected, and recall test was performed with a single subject group. recall accuracy of them was measured in two recall conditions(cue recall and target recall) and four training conditions(thought, thought suppression, thought substitution, and baseline). The results showed that recall accuracy in cue recall condition was better than in target recall condition, regardless of training conditions, and recall accuracy in thought condition was better than in other training conditions, regardless of recall conditions. Also there was significant interaction between recall and training conditions: For thought suppression. there was no difference between two recall conditions, whereas for thought substitution, recall accuracy in cue recall condition was better than in target condition. These findings indicate that thought avoidance strategies, including both thought suppression and thought substitution, are effective in avoiding the specific thought intentionally, and thought suppression and thought substitution could be applied by different mechanism.

  • 과학기술은 우리생활을 편하게 하지만 과학기술의 발달로 입는 환경오염은 갈수록 심각하며 개발된 기술을 악용햐는 사례가 늘고 있다. 과학기술을 사용하는 우리 모두가 올바른 판단을 할 수 있는 선한 사람이 되도록 노력해야 하는데 이렇게 인간을 선하게 만드는 것은 철학자의 몫이다. 그런 의미에서 과학과 철학은 함께 발전해야 한다고 생각한다.

  • 석유는 양질의 자원이었기 때문에 그 사용분야가 점차 확대되었다 .이것이 곧 과학기술의 내용이 된다 보통은 과학기술이 석유의 사용분야를 개척하는 것으로 생각하지만 ,그것은 원인이 아니라 결과로 볼만하다.
