We explored the performance improvement method of automated scoring for scientific argumentation. We analyzed the pattern of argumentation using automated scoring models. For this purpose, we assessed the level of argumentation for student's scientific discourses in classrooms. The dataset consists of four units of argumentation features and argumentation levels for episodes. We utilized argumentation clusters and n-gram to enhance automated scoring accuracy. We used the three supervised learning algorithms resulting in 33 automatic scoring models. As a result of automated scoring, we got a good scoring accuracy of 77.59% on average and up to 85.37%. In this process, we found that argumentation cluster patterns could enhance automated scoring performance accuracy. Then, we analyzed argumentation patterns using the model of decision tree and random forest. Our results were consistent with the previous research in which justification in coordination with claim and evidence determines scientific argumentation quality. Our research method suggests a novel approach for analyzing the quality of scientific argumentation in classrooms.

The study examines how the discourse on infants' smart media use has been constructed under media-saturated situations. Infants' use of smart media has been regarded as a dangerous activity, rate of overdependence has been increasing. Newspapers during the recent three years (2018-20) were analyzed. The most prominent speakers in the news field were smart media content producers and platform operators. There were negative views and concerns about infants' smart media use by academics, civic groups, and parents. However, the industry went beyond these risk discourses and gave positive meaning: Smart media was redefined as safe media for infants and reliable childcare helpers for parents. Parents were portrayed as those responsible for their children's media use and in need of help for childcare, rather than being blamed for their children's overdependence on smart media. Digital parenting seems to be emerging as an acceptable and practicable way of childcare rather than harmful and incomplete parenting.

As the information society gradually advances, various opinions overflow and their complexity increases. As the results, it was made more difficult to derive important issues and properly respond to those problems. Accordingly, it is necessary to get a handle on emerging problems in education in addition to existing discourses and issues. This study aimed at examining the issues of education by analyzing the petitions posted under 'parenting and education' category on National Petition board. In order to offer objective and detailed results, we employed the topic modeling based LDA algorithm, which is an effective method to extract topics in multiple documents. Nine topics were derived as the result of the analysis and the relationship among those topics was visualized. The values of this study exist in that the derived topics represent important issues that reflect the public opinions.

This study examined current system of qualification for dance teacher and curriculums along with their actual state, and sought to suggest methods to improve system of qualification for teacher among secondary school dance teachers by type and curriculums. Firstly, through literature analysis, the study examined systems and methods related with acquiring certificate for the current secondary school teacher (2nd grade) and for culture & art teacher for physical education (2nd grade) at the time when preliminary teachers qualified as secondary school dance teacher turned out. And then, using instrumental case study, it analyzed main issues and discourses by examining the cases in which they acquired qualification for secondary school teacher and qualification for dance teacher. Building on this, the study suggested how to improve systems in regard to qualification for dance teachers among regular teachers of secondary school, acquisition path, method and curriculum.

At the beginning of the Roman imperial period, moralizing authors criticized a material from the East that quickly gained popularity among the elites: silk. During Late Antiquity, the trade, production, and use of purple-dyed silks increasingly became the privilege of the emperors. While literature, court poetry, and laws give insights into the discourses surrounding silk, they are rather unspecific concerning silk qualities. This contribution analyzes the scattered descriptions of silks in Greek and Latin texts in a diachronic perspective, with a focus on the 1^st cent. BCE to the 4th cent. CE, paying particular attention to the terminology, products, origins, and qualities of silk. The aim is to build a framework for comparisons with archaeological silk finds and other textile terminologies along the Silk Roads. Here, the silk finds from the oasis city of Palmyra/Tadmor in modern-day Syria, dating from the 1st cent. BCE to the 2nd cent. CE, will be used as a case study for the early imperial period. Taking these silk finds as a comparison, it will be shown that Greek and Latin terminology does not match the variety of silks known in the Mediterranean. Rather, linguistic differentiations focus on the forms in which silk reached the Mediterranean, as skeins, yarns, and fabrics, as well as on the different kinds of silks that were produced in the West, namely pure silk and half-silken fabrics, checkered "scutlata" damasks, purple-dyed, and gold-embellished silks. In contrast, silks from the East were subsumed under the term for "silks from the silk people" or simply "silks". Moreover, ancient authors do not use the terms in the same way. These findings show the limitations of Western silk terminology and the importance of combining archaeological and written sources.

This study was conducted to provide implications so that teachers' voices are heard in the social consensus for future schools by exploring teachers' needs for future school spaces. A qualitative study was performed to listen to teachers' voices directly, and 10 teachers from "A" Elementary School (tentative name) participated in the study. The study 1) recognized the emergence of learning that transcends time and space, and emphasized the importance of an ICT-based informatization environment that can support such learning, 2) confirmed the characteristics of futuristic school spaces centered on "tradition" and "technology," 3) recognized the importance of learning community spaces, 4) emphasized "variable" classrooms for flexible teaching and learning activities, and 5) confirmed the need to introduce eco-friendly elements and provide support for those who may be vulnerable in high-tech learning environments. Finally, the study concluded that teachers need systematic education and experiences that contain sufficient important discourses related to future schools such as "eco-friendliness" and "connection with local communities".

A transboundary environmental problem refers to an environmental problem that goes beyond a country's territory and damages neighboring countries. It is a difficult problem because, basically, it is a natural, rather than intentional, effect, and it is extremely hard to make a scientific consensus on the cause-effect relations between upstream and downstream nations. Air pollution, especially PM 2.5 and PM 10, is one of the typical cases of transboundary environmental problems in the Northeast Asia. This paper analyzes the constraints of environmental cooperation between China and South Korea to address transboundary air pollution issue. It argues that lack of trust and ideological hostility, rather than, scientific uncertainty, is the biggest obstacle for effective cooperation, and these hostile discourses and ideas are mostly generated by media in the downstream nation, the South Korea. In order to identify how South Korean media frames this issue, this paper searched newspaper articles in the six representative South Korean newspapers during the period of 2014 and 2020, and analyzed about 2,000 articles selected. It finds that South Korean media has framed the transboundary air pollution as a China bashing and related domestic political cleavage issue, while it neglects to show the cooperation attempts that the two countries have made to date. Also, while the media focuses on China hate frame, it has never reported the Chinese government's domestic policies to reduce air pollution and their results. Media's overuse of hate and blame frames not only has disrupted trust building but also it will delay a possible turning point of environmental cooperation between the two countries in the future.

Purpose - Although the government and civic groups do not always confront each other over the Me Too movement, the two stakeholders are often conflicted. For example, the two interested parties may have different positions in the gender conflict and be often hostile due to debates over how to institutionalize and distinguish actual harm from innocence. In this situation, the strategies of the two stakeholders for their own ends are inevitably interdependent. This paper is a study on the strategic reciprocity of interested parties in relation to the Me Too Movement, which has recently raised a new discourses in our society. Design/methodology/approach - We derive equilibrium of the reciprocity between civic groups(collectively referred to as the Me Too Movement Headquarters) leading the Me Too Movement and government that must preemptively respond to new social issues, and analyze how changes in some external conditions affect the reactions of the two stakeholders. For this purpose we rely on economic methodology. Findings - In the reciprocity between the two forces, we derive an equilibrium composed of the pair of the government's optimal response level and the civic group's optimal strategy, and further derive the comparative static results according to changes in external conditions. Analysis results are mixed with intuitive results and non-intuitive ones. However, even if the result is not intuitive, rational reasoning is possible as long as it is derived through a rigorous model, and it has several implications. Research implications or Originality - Although this study is a positive approach, it is meaningful as a starting point to explore practical discussion directions and alternatives by adding another new perspective and approach to research in other social science fields with many normative studies.

This study originates from the examination of both Soviet Russia's and contemporary Russia's tabula rasa that numerous comprehensive national exertions have been trying to overcome, relying on the creation of numerous national emblems, political symbols, and even folkloric materials. With this mind, this work substantiates how the political and cultural symbols have been created in the contemporary socio-political and socio-cultural discourse in Russia. As with the political symbols that most recently been studied by Lee Trepanier, it must be recognized that contemporary social movements and political discourses have failed to "articulate a concrete political vision that reflects a consensus among elites, nor have any gained popular support" as the author confessed already. Concomitant to this general consensus, as Roy Medvedev has put it, we can contend that "today's leaders in Russia have no new ideology, and the mass of the people have no strong new national idea."

In the absence of the alternative public space of women in Japan, the experience of the "Bongseonhwa" was interpreted as the public domain of Japanese society as a public domain, a confession that focused on gender discrimination in the patriarchal system of Japan, Most of the enemy discourse is. These alienated discourses are the product of the efforts of women in Japan who do not want to forget about the traces and memories that can not be incorporated into the big narrative. It can not be denied that the women in the society of Japan have been excessively excluded and alienated by national ideology and patriarchal ideology. The meaning of presenting them through "Bongsinghwa" is the resistance of the minority, and it is the expression way of reconstructing and strengthening the identity of the women, and it is said to be a space of symbolic meaning. It is further clarified that it is based on a narrative that creates a new life area for coexistence with Japanese society, on the other hand, by constantly searching for the linkage with the motherland, held by women in Japan. As a result, between public social phenomena and private living space, confirmed that it conflicts with repetitive internal contradiction of controlling power and confirmed that complicated and detailed material of women living in Japan who undergo double discrimination What has been expressed over a period is considered to be a resistance expression and a will of expression of reconciliation to coexist with Japanese society. I have attempted to analyze the confessed alienated discourse of "Bongsinghwa" by classifying it as . As a result, it is confirmed that the public social phenomenon and the private life space are confronted with the repetitive internal contradictions of the power of domination, and the expression of the complex and detailed material of the discriminated women in Japan over a long period of time is a resistance to symbiosis with Japanese society And the will of the conversation.
