  • In this paper, we propose a representation method of emotions in RIDE(Robot Intelligence with Digital Emotion) project. The method used in RIDE not only represents the emotional state in James-Lange Theory but also represents that of the Cannon-Bard Theory. Furthermore, our method allow the memorization of an emotion so as to process the self-inflicting emotion mentioned in the Schafter-Singer Theory. We also allow the similarity and differences in the characteristics by compaing of two emotions.

  • Lee Sang, a poet and a architect, made new experimental poems that was influenced by quantum mechanics and theory of relativity that were published in the early 1900's, and he showed his new view of the world that transcended time and space limit through his poems. In this essay, I studied and analyzed on the links between his view of the world and modern design view with as the central figure his text, 'A Written Promise of The Line' The result is that he fellow the cyclic world view which the world consisted of cycles within cycles, of immense duration and the scientific view of the world which the universe and me are one flesh.

  • Unlike Korean science curriculum's continued push for "relevance of contents" to reduce the burden of learning on students, IB DP (International Baccalaureate Diploma Programme) is chosen in many countries and the number of IB world schools continues to grow, although it contains not only a large amount of learning but a substantial amount of content that requires quantitative calculations. Through this study, we suggest implications for Korean science curriculum and textbook, by comparing the constructions of chapters, the achievement standards, the learning contents, and the formulas of physics textbook, focusing on the 'relativity' unit of the 2015 revised national curriculum and IB DP, and by analyzing the questions of college scholastic ability test (CSAT) and external assessment (EA).

  • This study aims to provide a theoretical examination of symmetry and its implications for science education. For this purpose, first, we examined the way of thinking of Western science in general through ancient Greek scholars. Second, we divided the perception of symmetry into ancient and modern times. Third, we draw out the implications for science education. The results of this study show that, first, the way of thinking in Western science is 'abstraction', which began with Parmenides and was established by Plato. Second, the ancient perception of symmetry is symmetry as beautiful proportions and harmony based on abstraction, and the modern perception of symmetry is symmetry as an invariant perspective based on abstraction that seeks to find constancy in change. We examined Eratosthenes' experiment to measure the circumference of the earth as an example of ancient symmetry, and Galilean relativity or transformation as examples of modern symmetry. Third, the implications for science education are as follows. Awareness of symmetry can help educate students about the nature of science, as it is a central theme that runs through ancient and modern science. Second, the Eratosthenes' experiment and Galilean relativity or transformations are not represented in the 2022 revised curriculum, but could support understanding of science and key competencies and concepts. Finally, an integrated approach to science education centered on symmetry can have a positive impact on scientific attitudes and interest.

  • As is well known, logical positivists held the theory-independent of observation thesis(TIOT). On the other hand, the theories following the logical positivism typically represented by Hanson and Kuhn denied that there was a clear borderline between observation and theory, and held the theory-ladenness of observation thesis(TLOT). In order to mediate those theses I shall suggest a natural epistemic attitude (NEA) to the relation between theory and observation on the basis of the experimentalism. First, I discuss theories of Hanson and Kuhn as examples of views which profess TLOT. Then, I make a brief introduction of experimentalism and some critical discussions about TLOT follow from a point of the experimentalism: TLOT faces considerable counter-examples such as cases, 'observation precedes theory' and 'the combination of wrong theory and right observation'. I introduce a distinction between the guiding theory and the target theory in experimental situations and illustrate that TLOT loses its alleged power if we consider the distinction. Lastly, I suggest NEA, as conclusion of the paper, which can mediate among TIOT, TLOT, and experimentalism and takes a minimal ontology.

  • The Purpose of this study was an analysis of high school student's understanding level about concepts of special relativity through in-depth interview. The 8 participants were 10th grade students in H high school in Ulsan city, who were interviewed and analyzed in the results of the interview about basic concepts of special relativity using achievement checklist in 6 situations(principle of constancy of light velocity, principle of relativity, relativity of simultaneity, garage paradox, rocket paradox). As results of the checklist, the participants showed high achievement in the content level of simple phenomena and simple concepts related to special relativity. But they showed low achievement in the concept level for fundamental understanding of special relativity. As results of the interview, it was found that the participants decided the order of events depending on their intuition and had a difficulty to apply the coordinate system to real situation, even though they mathematically understood it. In addition, some participants who could not understand the inertial coordinate system explained paradoxes of relativity depending on their intuition and had learner's chaos. Finally, though high school students usually being in formal operational stage, some students had difficulty to draw phenomena of space and time in two dimensional plane.

  • If 1st order ZFC is consistent(has a model($M_1$)) it has a transitive denumerable model($M_2$). This leads to a paradoxical situation called 'Skolem paradox'. This can be easily resolved by Skolem's typical resolution. but In the process, we must accept the model theoretic relativity for the concept of set. This relativity can generate a situation where the meaning of the set concept, for example, is given differently depending on the two models. The problem is next. because the sentence '¬denu(PN)' which indicate that PN is not denumerable is equally true in two models, A indistinguishability problem that the concept <¬denu> is not formally indistinguishable in ZFC arise. First, I will give a detail analysis of what the nature of this problem is. And I will provide three ways of responding to this problem from the standpoint of supporting ZFC. First, I will argue that <¬denu> concept, which can be relative to the different models, can be 'almost' distinguished in ZFC by using the formalization of model theory in ZFC. Second, I will show that <¬denu> can change its meaning intrinsically or naturally, by its contextual dependency from the semantic considerations about quantifier that plays a key role in the relativity of <¬denu>. Thus, I will show the model-relative meaning change of <¬denu> concept is a natural phenomenon external to the language, not a matter of responsible for ZFC.

  • By the theories of the physics, the phenomena in the world are understood. And also these theories gave the influence to design the architecture. In this research, the contents which the thought of the physics gives a influence a building design is considered, and try to suggest the interrelation between the physics and architectural design. As the result, the architectural design on the influence of classical physics is based on the homogeneous space and the design focus on the style or form of the building with a geometry plan which is not concerned of the place. On the other hand, contemporary architectural design is based on the thought of the modern physics. By this concepts, the architecture is understood as the area contain the conditions of the circumstance and by interaction between buildings and the environment and by various viewpoints like cubism. And the architecture which is settled recently is shown of the diversity and atypical form.

  • We describe relations between modern cosmology and general relativity in the historical context. We reveal some ironies imbedded in Einstein's final correction of his gravitational field equation in the context of cosmology in 1917 which has apparently opened a new era of modern physical cosmology. The ugly (according to Einstein) correction term was introduced only to build a static cosmology which turns out to be in flat contradiction with observation. Somehow, however, it is the correction term which has saved the modern cosmology from the genuine creativity of nature continuously revealed by astronomical observations. Whether the present precision cosmology is also a correct one is often ignored by the practitioners but still a pressing open question left for future theoretical and observational pursuits.
