  • One of the characteristics in math -abstract concept- makes the students find difficulties in understanding general ideas about math. This study is about how much do the modeling lessons using the technical instruments which is based on the realistic mathematical theory influence on understanding the mathematical concept. This study is based on one of the contents the first grade of middle school students study, the function, especially the meaning of it. Some brilliant students being the objects of this study, mathematically experimental modeling lesson was planned, conducted. Survey on the students' attitudes about math before and after the modeling classes and Questionnaire survey on the effectiveness about the modeling class were conducted and their attitudes were recorded also. This study tells that students show very meaningful changes before and after the modeling class and scientific knowledge seems to be very helpful for the students to understand the mathematical concept and solve the problems. When scientific research and development get together with mathematics, students will be more motivated and be able to form the right mathematical concept easily.

  • Objective: The present study suggested practical measures for successful patent registration based on a review of success and failure cases of patent application filed based on inventions obtained from physical ergonomics research. Background: The protection of intellectual property (IP) contributes to economic growth and competitiveness and facilitates innovation and creativity. IP rights are pursued on research findings for effective technology transfer and commercialization; however, a patent application can be rejected if patentability requirements such as patent eligible subject matter, utility for industrial application, novelty, or non-obviousness are not satisfied. Method: Three successful and three failed cases of patent applications based on physical ergonomics research were reviewed, critical reasons for their successes and failures were examined, and measures were proposed to avoid failures in patent registration. Results: The following measures were identified based on the patent application case review. First, abstract ideas including logical procedures and/or mathematical formulas need to include use of tangible apparatus and methods in idea realization. Second, the provision of grace period inventor disclosure exception needs to be properly followed in case an invention is disclosed before filing of patent application. Lastly, a comprehensive analysis of prior art published or publicly known anywhere in the world and a claim preparation of distinguished, non-trivial features compared to prior art solutions are needed to avoid possible violation of novelty and non-obviousness. Application: The proposed measures can help to prepare a patent application with patent eligibility.

  • The modern trend in costumes, influenced by postmodernism, is to use of various patterns and images borrowed from diverse cultures of many ethnic groups. The Yi tribe studied in this paper is miner ethnic group in China, whose traditional costume is very splendid and modern. In addition, its embroidery or $appliqu{\acute{e}}$ pattern have a high artistic value in that its shapes are diverse, splendid and each one has its own peculiar elegance. As for the research method, I examined the Yi tribe's history, culture, traditional costumes and patterns through related books, research papers and inter web sites. As for the result, the Yi tribe's costumes consisted of a jacket, trousers or a skirt, an apron and a belt. Although the favorite color of the costume is black color, there are splendid embroidery or $appliqu{\acute{e}}$ decorations with the colors of red, yellow, green and purple on the chest or shoulder part of a jacket, the adjusting lines, cuffs or a part of a trousers and aprons. Patterns in their traditional clothing also show details that depict traditional cultural ideas that have long been formed in various fields, such as aesthetics, religion, philosophy, and customs. Moreover, most patterns displayed in their traditional clothing contain nature motifs and represent unique and beautiful designs; some patterns are even reminiscent of abstract paintings by modern artists. In conclusion, the traditional patterns of Chinese ethnic minorities reflect the values and notions of these races as well as decorative magnificence and a unique spiritual image. In other words, traditional patterns indicate the spiritual depth or symbolic stories beyond mere formative beauty.

  • The fraction concept consists of various meanings and is one of the abstract and difficult in elementary school mathematics. This study intends to find out the implication for introducing the fraction concept by comparing mathematics textbooks of Korea and Singapore. Both countries' students peformed well in recent TIMMSs. Some implications are as follows; The term 'equal' is not defined and the results of various 'equal partitioning' activities can not easily examined in Korea's mathematics textbook. And contexts of introducing fractions as a quotient and a ratio are unnatural in Korea's mathematics textbook in comparison with Singapore's mathematics textbook. So these ideas should be reconsidered in order to seek the direction for improvement of it. And Korea's textbooks need the emphasis on the fraction as a measure and on constructing fraction concept by unit fraction.

  • In February 2018, the Korean government established the "Comprehensive Plans for Government Innovation" in order to realize 'the people-centered government'. The core of the comprehensive plans is participation of the people, which is very similar to open innovation where social issues are solved by ideas and capabilities of the private sector rather than those of the government. Therefore, this study was conducted by extracting open innovation topics through topic modeling based on LDA(Latent Dirichlet Allocation) as English abstract-data from 2003, when the plans for open innovation was first announced, to April 2018. Based on the extracted results, it also conducted a comparative analysis with "Comprehensive Plans for Government Innovation." The study has significant implications in that it derives the relationship between the subjects, analyzes the present policies of Korea on open innovation and suggests directions for development.

  • The Gifts that Freobel devised in 1837 were the first instructional media using concrete and systematic toys as materials for early childhood education. The shapes of hexahedrons, cylinders and balls and conception of point, line, plane and six colors shown in the forms of Freobel's Gifts are the basics of formative elements in modem design. However, the Gifts, or educational toys, which were presented to practice Freobel's educational ideas actually in the educational fields were hardly examined or analyzed from the viewpoint of design. In this study, the structural principles, which were applied to the plastic formation of the Gifts under the influence of Freobel's educational philosophy, are examined by analyzing the visual formative characteristics of Freobel's Gifts. Accordingly, through an analysis on the formative principles of the Gifts, it is studied how a system of abstract and philosophical thought was visually applied to forms. This study is a probing research on the formative characteristics presented in the Gifts and is an investigation of formation theory about geomatrice forms. The effects and problems of the formative features of teaching materials for little children are also examined from the viewpoint of design in this study.

  • As many changes in the future society represented by the age of artificial intelligence(AI) are expected to come, efforts are being made to draw the shape of the future education and various research methods are being employed to support the attempts. While many research studies use methods for deriving generalized results such as expert survey and trend analysis in along with a review of literature, there are attempts to apply the scenario methodology to explore ideas and information needed within a changing context. A scenario method, one of the experiential learning strategies, aims to seek various and alternative approaches by establishing a plan from the present conditions considering future changes. In this study, in-service teachers' perceptions and expectations of the interactivity between human and AI teachers were visualized by applying the role-play presentation technique that grafted the concept of role-play game to the scenario method. In addition, the mandal-art method was introduced to support in conducting productive discussion during the teachers' collaboration. This method appeared to help to depict teachers' perceptions of AI teachers in the detailed and concrete form, which may flow in the abstract otherwise. Through analyses of the teachers' role-play presentations with the implementation of the madal-art method it was suggested that most teachers would want to collaborate with an AI teacher for improved instruction and individualized student learning while they would take the instructional authority over the AI teacher in the classroom.

  • In his early poems, Wallace Stevens shows us different gestures, compared with his later poems, when he acquires reality by faculty of imagination. The former is made of ontological violence while the latter is revealed by bareness of less sensuality. However, they are the identical gestures, though from different angles, to accomplish things as they are rather than the ideas of things. In "Sunday Morning," ontological violence occurs in such epistemological couples as thought and thing, mind and world, and imagination and reality. Especially, in order to recuperate his poetic reality, Stevens undermines the traditional hierarchy between heavenly divinity and earthly divinity. In the poem, Christianity faces a critical challenge and then it is disempowered by the earthly divinity. Additionally, by disadvantaging religion, he wants to raise his poetic issue of the faculty of imagination to acquire reality. Stevens' concept of imagination is less subjective and more transcendental than Kantian one. After the ontological violence, Christian divinity and mythic gods leave ontological boundary for earthly divinity in an ambiguous way. In other words, between "Sunday" and "sunny day," the ontological conflicts haunt us throughout the poem as if the violence would happen between imagination and reality. For Stevens, both Christian divinity and mythic gods are mere obstacles to real divinity; both play a mere role of imagination before reality is revealed. Whatever reality is, imagination is always ready to draw an ontological line of reality in an ambiguous way, regardless of how long it lasts. In general, most ontological violence requires such physical remnants of conflicts as borderline, deaths, and pains which still prevail in the poem. Those ontological remnants remain to be found on earth. The sky is an abstract borderline between heaven and earth because in a sense, it belongs to both earthly landscape and heavenly sphere. Without any ontological borderline or threshold, there is no recognition of the divinity because the vitality of divinity is inflamed in continuous transgression of the other. After the final ontological conflict between heaven and earth, there remains only ambiguous borderline near the earth beside the friendlier sky.

  • This study aims to suggest the conceptual framework for the Nature of Technology (NOT) by examining the current researches regarding the NOT in science and technology education and to analyze the conceptions of experts in science, technology, and engineering fields based on the framework of NOT. The NOT conceptual framework developed in the study consisted of the six domains of NOT, which are 1. Technology as artifacts, 2. Technology as knowledge, 3. Technology as practice, 4. Technology as system, 5. The role of technology in society, and 6. History of technology. Also, the results of analyzing the conceptions for the 30 experts in science, technology, and engineering fields emphasize on the three domains of the 3. Technology as practice, 4. Technology as system, and 5. The role of technology in society among the 6 domains of the framework of the six domains of the NOT framework. This findings are different from the results of previous researches conducted in science and technology education for exploring the conceptions of NOT in the POV of the public and students. As such, the results show that while the public and students possess naive ideas on NOT only focusing on the technology as products and tools, experts in science, technology, and engineering fields possess the authentic views of the NOT reflecting the complex and abstract concepts of technology in terms of the perspectives of philosophy of technology.

The Question of 'State and Art' with regard to Soviet Socialist Realism (소련 사회주의 리얼리즘에 관하여: '국민과 예술'의 문제)

  • The artworks of Socialist Realism of the former Soviet Union, with the beginning of the 21st century, are gaining a new attention from art collectors. One reason for this might consist in the fact that relevant art pieces exemplify the ways in which they visualize ideas on the basis of their high-profile art tradition and also in which they integrate their utopian ideals with mysticism. These aspects of the Soviet art goes far beyond the wide-spread assumption that their art, as a means of propaganda, principally represents a political allegiance to the system. With Stalin coming into power in the 1930s, the artistic trend of Socialist Realism obtained a nationwide sympathy and support from people, giving birth to a new art which essentially corresponded to the demands of the political power. An official art current of the USSR over the period from the 1930s to 1950s, Socialist Realism was in tandem with the Communist commitment to the party and popularity, symbolizing a loyalty to the cause. It was thus characterized by plainness and lucidity so that ordinary people could gain easy access to art. Its salient feature, over an entire range of art, was an optimistic pursuit of a utopian dream. Therefore, it tallied with the popular sentiment for a Communist paradise, giving form to their beliefs in human agency working at the materialist world and also to such abstract concepts as force, fitness, and beauty by adding even mythical ideals. Its main subject matter includes harvest feasts of collective farms, imaginary socialist cities, grand marches of heroic laborers and in this way it served as a propaganda for a sacred utopia of socialist totalitarianism. On the other end of the spectrum, however, rose the second camp of art, which put an emphasis on bona-fide artistic activities of plastic art and on an artist's personal expression and freedom, as opposed to the surface optimism of Socialist Realism. Central to the Russian Avant Garde art, which prized the above-mentioned values, were Malevich's Geometric Abstraction and A. Rodchenko's Constructivism. Furthermore, in the transitional era of the late 20th century and the 21st century it was recognized that film art or electronic media art, rather than traditional genre of paintings, would function as a more efficient way of propaganda. These new genres were made possible by ridiculing the stereotypes of the Russian lifestyle and also by ignoring ethical or professional dimensions of artworks. That is, they reinvented themselves into a sort of field art, seemingly degrading the quality of artworks and transforming them into artifacts or simulacres in the very sense of post-modernism. The advent of the new era brought about the formation and occupation of pop culture of the younger generations, calling into question the idea of art as the class-determined. It also increased the attention to field art, which extensively found way to modern art centers, galleries, and exhibition projects. It can be stated that this was a natural outcome of human nature.
