The purpose of this study was to examine how group argumentations mediated individual arguments by analyzing physics teachers' group argumentation and individual follow-up written arguments. Five in-service physics teachers participated in this study, two middle school and three high school teachers. The topics of argumentation included physics topics and pedagogy of them. Findings showed that the teachers constructed much more elaborated individual written arguments than group argumentation, which seemed to be resulted from different perceptions of teachers' verbal and written argumentations. Also, in their written arguments the teachers selectively utilized their colleagues' ideas shared during group argumentation. Lastly, teachers' argumentation showed different features between topics of physics and physics pedagogy. These differences were related to their orientations toward argumentation about content knowledge and teaching. These findings shed light on a productive physics teacher professional development in argumentation.

We agree with Hanna and Jahnke's assertion on the use of arguments from physics in mathematical proofs and analyze their educational example of the use of arguments from physics in the proof of the center of gravity of a triangle. Moreover, we suggest practical models for the center of gravity of a triangle for the demonstration in a classroom. Comparing with the traditional mathematical arguments, the role of concepts and models from physics in arguments from physics will be clearly pointed out. Also, the necessity for arguments from physics in the classroom will be discussed in this paper.

의식에 관한 가장 흥미 있는 최근의 과학적 작업들 중 철학적으로 문제가 되는 다수는 시각으로부터 나왔으며 그 중 특히 맹시 현상은 심리철학에 있어서 의식, 지각, 그리고 지향성의 개념에 문제를 제기한다. 맹시 환자들은 후두엽 피질의 두뇌 손상으로 인하여 생긴 암점(Scotoma) 때문에 현상적으로 의식적인 과정을 경험할 수 없으면서도 그들의 보이지 않는시야 영역에 대하여 보통 시각을 가진 사람들과 상당히 비슷하게 기능을 발휘한다. 이러한현상은 의식이 행동을 제어하는 데에 과연 인과적 역할을 하는지에 대한 문제들, 심리철학에서 뿌리깊게 논의되어왔던 의식의 기능과 부현상론에 대한 문제를 제기한다. 즉, 맹시 현상은 현상적 의식이 실재하지 않는 것이거나, 존재하더라도 어떤 인과적 효력을 가지지 않는 부수현상적인 것이라는 견해를 강하게 지지하는 것 같다. 이와 함께 인간과 동일한 물리적 구성과 행동을 가지지만 의식적 경험을 결여하는 피조물인 좀비(zombie)의 이론적 가능성이 제기된다. 이를 지지하기 위해서 초맹시(super-blindsight)의 개념과 사례가 제안된다. 이 논문은 맹시 현상을 통해서 현상적 의식의 실재성을 부정하려는 논변들을 반박하고, 의식은 행위의 수행에 관련될 뿐만 아니라 인지에 있어서 중요한 역할을 한다고 논한다. 따라서, 역설적으로 맹시 사례가 오히려 현상적 의식이 인과적 역할을 가진다는 감각질 실재론의 견해를 지지할 수 있다고 논증할 것이다.

The purpose of the study is to understand the change process of middle school students' physics conceptions by the presented types of conflict situations. 274 middle school students were selected from one school in Pusan, however 257 students were participated in all the procedure of the study. After we classified students' physics conceptions into scientific and unscientific conceptions, presented three types of conflict situations. In this study three different cognitive conflict strategies were adopted; the first one is logical arguments(LCS: logical conflict situation), the second is actual demonstration(DCS: demonstrational conflict situation), and the third is two strategies together(DLCS). In this study, first, we investigated the change process of students' physics conceptions by three types of conflict situations. Second, we compared the effect of three conflict situations presentation, which includes positive effect by conceptual change from misconception to scientific conception and negative effect by conceptual change from scientific conception to misconception. Third, we studied characteristics of conceptual change by characteristics of conflict situations. In result, DLCS group and DCS group were more positive effect than LCS group in mechanics, DLCS group and LCS group were more positive effect than DCS group in electricity. It seems that mechanics are closely related to physical experiences, while electricity are more abstract.

Determinism and compatibilism have thought that libertarianism contradicts the scientific view. This paper demonstrates that the hypothesis that free will exists does not cause any problems and contradictions, while maintaining pro-scientific view. Rather, determinism lacks scientific and demonstrative bases. At first, I reject dualistic self by assuming identity theory of the self and physical body & brain. Free will is a functional concept or property that can have multiple realization. Therefore we can recognize whether aliens or robots have free will through observation on their acts. 'Free will' is a functional kinds term like 'digestion'. As we know we have digestive function, we can know that we have free will even before knowing the necessity of its existence by understanding micro structure of human free will. The judgement that an individual has free will function depends on whether it has particular actions. Those actions are controlling and restraining actions in context, predicting future, making elaborate conditional sentences, etc. Real being of free will is the physical occupant of the function that makes those actions. Determinism is based on various kinds of misconceptions and misunderstandings. Determinists often confuse necessity of physical law and determinism. Another decisive misunderstanding is that free will postulates same conditions and different results from the same point of time. However, free will postulates that the two points of time are different. Because determinism is unnecessary redundant hypothesis influenced by religions, according to Ockham's Razor, determinism should be eliminated.

A posteriori physicalists criticize non-physicalist arguments based on the framework of two-dimensional semantics. Most of them argue for physicalism based on the analogy between scientific identity statements and psychophysical identity statements. This paper argues for another version of aposteriori physicalism, so called physicalism employing 'phenomenal concept strategy' or 'exceptionalist strategy', which appeals to merely the nature of phenomenal concept without recourse to a semantic framework. Loar's phenomenal concept strategy employs the aspect of our recognitional ability of objects in criticizing non-physicalism, leading to the argument that phenomenal concepts are 'exceptional' in applying conceivability-possibility link. I critically examine Stoljar's, Chalmers', Raffman's criticisms against Loar's exceptionalists strategy. Loar's phenomenal concept strategy reflects well our psychological aspects surrounding the acquisition and the possession of 'phenomenal concept'. In several respects, Loar's exceptionalist version of a posteriori physicalism is the best explanation for accounting for both the explanatory gap and the a posteriority of psychophysical identity.

The concept of 'Picturing' is beyond the 'Illusion' of traditional art in the Digital Media era. It is a 'Suffering' of the 'Re-appearance' that is masquerade the 'Actual' as a 'Digital Apparition.' This study aims to concern the point of view on the above subject; the 'Picturing' through the analysis of communication problems in the digital era. To begin with, need to define the concept of 'Picturing' and how it is expected to have a role through the accessibility of medium use, intervention by body and images. Also, I suggest a new approach to 'Picturing' as a new mutual communication method. Body, Digital media, and Image. These three principles of 'Picturing' create huge benefits to our world/nature whether we want it or not. It seems to become more and more of powerful self-replicating organism. We have to be aware what sort of images are surrounding us and how transmitting it to where in/on our body via newest sophisticated media we use. 'Picturing' is an invasion of ordinary, no longer exists pleasure for body, no longer speaks intension of its next destination. It strongly self-grows and also controls us in the name of Digital media era. However, 'Picturing' is a mode of re-imaging activity and also suggestion of re-appearance practice.

Environment-friendly design becomes one of the main issues of the contemporary design. It has been developed with the advent of the organic view of the wend. It started as the environment-protective orientation and then enlarged its boundary including the designs which aims to revive the organic relationship between human and nature. Recent design approach in environment design emphasizes to be 'synchronized with the nature' and its basic attitude is the revival of the right relationship between man and nature. It also can be described as the design for Green Amenity. This paper researches on the concepts, types and the roles of the environmentally-friendly design. There are two basic concepts : one is environment-protective attitude and the other is the attitude which emphasizes the function of Green Amenity. This paper focuses on the latter approach. Through the analysis of the necessity and the function of the environmentally-friendly design, it aims to prove the fact that valuable human life need the design which connects human life aye with natural environment.

The purpose of this paper intuitively shows the exact and logical explanation of Independent Event and Dependent Event. In actual classrooms, teachers have difficulty in describing the connection between those events and real life. Some teachers have wrong perceptions on the definition of those events. For example, they may not realize exactly what P(B A)=P(B) means and may not explain intuitively the original meaning of why it is independent event. Also they believe that Independent Event and Dependent Event do not always match with real life. This paper, therefore, tries to prove intuitively the exact meanings of those events in the Verbal Form with some examples and it proves that those events exactly match with real life. It is expected that this paper will greatly contribute to the improvement of probability education.

This paper intends to focus on the practical activities and historical significance of network art, that is, 'net art' as an artistic form that depends on network technology. This is because the appearance of net art, which constructs a new interactive art that cooperates and exchanges with each other beyond the boundaries of time and space, can be a contemporary alternative in overcoming the limitations of traditional art. Another important research area to be considered in this paper is net art curating, as well as considering the significance of net art in art history. As new media art that is defined as a 'process' rather than a complete object, net art is a digital art that requires functions such as aesthetic appropriation, dissemination, and mediation performed online, unlike physical presentations with high perfection in exhibition halls. It is accompanied by a new social and cultural curatorial. This appearance requires both artists and curators to reorganize the strategy that net art curating in technoculture should have. Therefore, this paper attempts to question the creative strategies of net art in the wave of globalization in the 21st century, and to examine the artistic meaning and critical value of the experimental net art curatorial method that emerged through the realm of new technology and media. For this purpose, this paper demonstrated key examples of net art works and exhibition projects that started with Fluxus in the 1960s and are spreading all over the world in the 2000s.
