  • Visualization techniques are transformed into reliable representations through socio-technological processes which include the agreement on the instrument and the embodiment of practices in relevant scientific communities. Visual representations thus produced are justified by realistic and epistemic virtues in science. This paper analyzes different visual images presented in the scientific papers of two research groups who argue different theories about the mechanism of face perception. These two scientific groups use the same fMRI technology; yet, different experimental paradigms and visual stimuli change their hypotheses into distinct testable theories, which in turn lead to different evidences to support their own theories. Visual evidences are intermediate representations which lie between fMRI brain images and scientific theories, and theoretical models obtain the scientific value based on the consistency in the chain of visual representations. This study shows that representations in science tend to be good representations within the context of scientific communities. It will provide a chance to think of the value and limit of the scientific knowledge

  • South Korea's state health insurer, the National Health Insurance Service (NHIS), is in the process of a compensation suit against tobacco industry. The tobacco companies have habitually endeavored to ensure favorable outcomes in litigation by misusing scientific evidence or recruiting scientists to support its interests. This study analyzed strategies that tobacco companies have used during the NHIS litigation, which has been receiving world-wide attention. To understand the litigation strategies of tobacco companies, the present study reviewed the existing literature and carried out content analysis of petitions, preparatory documents, and supporting evidence submitted to the court by the NHIS and the tobacco companies during the suit. Tobacco companies misrepresented the World Health Organization (WHO) report's argument and misused scientific evidence, and removed the word "deadly" from the title of the citation. Tobacco companies submitted the research results of scientists who had worked as a consultant for the tobacco industry as evidence. Such litigation strategies employed by the tobacco companies internationally were applied similarly in Korean lawsuits. Results of tobacco litigation have a huge influence on tobacco control policies. For desirable outcomes of the suits, healthcare professionals need to pay a great deal of attention to the enormous volume of written opinions and supporting evidence that tobacco companies submit. They also need to face the fact that the companies engage in recruitment of scientists. Healthcare professionals should refuse to partner with tobacco industry, as recommended by Article 5.3 of the WHO Framework Convention on Tobacco Control.

  • In this study, we developed tasks including cognitive scaffolding for students to explain scientific phenomena using valid evidences in science classroom and sought to investigate how tasks influence the development of small group scientific argumentation. Heterogeneous small groups in gender and achievement were organized in one classroom and the tasks were applied to the class. Students were asked to write down their own ideas, share individual ideas, and then choose the most plausible opinion in a group. One group was chosen for investigating the effect of tasks on the development of small group argumentation through the analysis of discourse transcripts of the group in 10 lessons, students' semi-structured interview, field note, and students' pre- and post argument tests. The discrepant argument examples were included in the tasks for students to refute an argument presenting evidences. Moreover, comparing opinion within the group and persuading others were included in the tasks to prompt small group argumentation. As a result, students' post-argument test grades were increased than pre-test grades, and they argued involving evidences and reasoning. The high level of arguments has appeared with high ratio of advanced utterances and lengthening of reasoning chain as lessons went on. Students had elaborate claims involving valid evidences and reasoning by reflective and critical thinking while discussing about the tasks. In addition, tasks which could have various warrants based on the data led to students' spontaneous participation. Therefore, this study has significance in understanding the context of developing small group argumentation, providing information about teaching and learning context prompting students to construct arguments in science inquiry lessons in middle school.

  • To understand seasonal changes it is necessary to understand the relationship between celestial bodies in a three-dimensional space, and to this end, modeling activities in which students directly construct, use, evaluate, and modify three-dimensional models are important. In this study, the process of elementary school students using globes and light bulbs to model Earth's motion in a three-dimensional space as a cause of seasonal changes was analyzed. Seventeen sixth graders participated in the modeling process. After exploring phenomena and concepts related to seasonal change, students constructed models using globes and bulbs and used them to explain seasonal changes. Video data recording students' modeling process, students' activity sheets, and transcripts of post-interview were used as research data, and data triangulation was conducted. The modeling level analysis framework was also developed based on previous studies. In particular, the framework was developed in detail in this study in consideration of the concept of Earth's motion as well as understanding model and implementing modeling. In the final analysis framework, the 3D modeling level was classified from level 1 to level 3, and student performance that may appear at each level was specified. As a result of the study, there were two main levels of modeling using globes for elementary school students to explain seasonal changes. The rotation and tilt of the axis of rotation and revolution of the earth were considered but the level at which empirical evidence was not used (level 2), the level at which empirical evidence was used to explain seasonal chages (level 3). However, even when students use empirical evidence, it did not lead to the construction of a scientific model. In this study, the cause was explored in relation to the characteristics of the tool used for modeling.

  • The presnt study reviewed two contrasting models, fixed-resolution slot versus flexible-resource hypotheses, for the representational characteristics of visual working memory (VWM), and emphasized the necessary efforts for resolving their conflicting arguments. To accomplish this goal, the review explored the background hypotheses of the object-based versus parallel independent storage models, and introduced theoretical bases for their contrasting claims. The review then evaluated validity of empirical evidence provided in the studies to support each model, and attempted an understanding of their neurophysiological background. The study further emphasized the necessity of theoretical and methodological reconsiderations to resolve their conflict as well as the necessity of obtaining converging pieces of evidence to accomplish the resolution.

  • Log data collected from mobile devices contain diverse and meaningful personal information. However, it is not easy to implement a context-aware mobile agent using this personal information due to the inherent limitation in mobile platform such as memory capacity, computation power and its difficulty of analysis of the data. We propose a method of selective inference for modular Bayesian Network for context-aware mobile agent with effectiveness and reliability. Each BN module performs inference only when it can change the result by comparing to the history module which contains evidences and posterior probability, and gets results effectively using a method of influence score of the modules. We adopt memory decay theory and virtual linking method for the evaluation of the reliability and conservation of casual relationship between BN modules, respectively. Finally, we confirm the usefulness of the proposed method by several experiments on mobile phones.

  • 인문학은 인간에 대한 깊은 성찰과 세계에 대한 폭넓은 조망에서 잉태한다. 이런 인문학 교육은 인문대학만이 아니라 전반적인 의료교육 현장에 접목되어야 한다. 따라서 인문학 역시 현실을 도외시한 언어유희가 아니라 현실속의 사회 문화적 통로를 접근하는 방식으로 도입되어야 한다. 인문학적 성찰은 전문가만의 소유물이 아니다. 특히 의료인문학적 성찰은 죽은 몸이 아니라 살아 있는 몸을 다루는 임상행위의 전제이다. 이렇게 살아 있는 생명의 몸을 다루는 의학 부문에서 과학적 설명의 적용범위와 그 실현가능성은 아직 충족되고 있지 않다. 이는 과학탐구 대상으로서의 톰과 증상과 치료의 대상으로서의 구체적인 의학적 몸 사이의 간극이 있음을 무시할 수 없다는 점이다. 인문학적으로는 설명 장르의 몸에서 제외된 이해 장르의 몸이 다시 조명되어야 한다. 정확히 말하면 설명 장르와 이해 장르가 통합되어야 한다는 뜻이기도 하다. 이러한 인문학적 반성이란 추상적 이론으로 그쳐서는 안 되며, 의학과 의료 현실에 어떻게 실천적으로 적용가능한지를 질문하는 일이다. 이 논문에서는 그 적용사례로서 증거중심의학(EBM)과 문제기반학습(PBL)를 다루었다.

  • There has been an enormous progress in understanding of how genes contribute to both normal and abnormal development. Also many laboratory works are exploring the intricacies of how to develop in the human central nervous system. Understanding the mechanisms of cortical development gives essential insight into the pathogenesis of many genetic and acqured developmental psychiatric disorders, including autism, schizophrenia, and teaming disorder. Genes have been implicated in an ever-increasing number of disorders. Advance in genetics have begun to clarify the molecular basis of not only single-gene disorders, but also more complex phenotypes.
