The purpose of this study is to draw implications for designing online tools to support monitoring in collaborative learning. For this purpose, eighteen research papers that explored learner dashboards and group awareness tools were analyzed. The driving questions for this analysis related to the information and outcomes that must be monitored, whose performance they represent, and who monitors the extent of learning. The analytical frameworks used for this study included the following: three modes of co-regulation in terms of who regulates whose learning (self-regulation in collaborative learning, other regulation, and socially shared regulation) and four categories of dashboard information to determine which information is monitored (information about preparation, participation, interaction, and achievements). As a result, five design implications for learner dashboards that support monitoring were posited: a) Monitoring tools for collaborative learning should support multiple targets: the individual learner, peers, and the entire group; b) When supporting personal monitoring, information about the individual and peers should be displayed simultaneously to allow direct comparison; c) Information on collaborative learning achievements should be provided in terms of the content of knowledge acquired rather than test scores; d) In addition to information related to interaction between learners, the interaction between learners and learning materials can also be provided; and e) Presentation of the same information to individuals or groups should be variable.

Red ginseng is a widely used dietary supplement and medicinal herb, and there are so many forms of ginseng products including tea, extract, capsule and jelly. The purpose of the present study was to propose some amendments on ginsenoside content of red ginseng products in Korea. For this purpose, we analyzed red ginseng products for simultaneous determination of 26 ginsenosides by ultra performance liquid chromatography with diode array detector. Some developmental aspects of Korea's ginsenoside content standard regulations for red ginseng products are needed to be examined as follows : Firstly, we proposed that four ginsenosides ($Rb_1$, $Rg_1$, Rf and $Rg_3$) would be detected in red ginseng products. Secondly, in case of red ginseng extracts, the sum of $Rb_1$, $Rg_1$ and $Rg_3$ would be 4.0 mg/g. The two proposals are helpful to comprehensive evaluation of quality of red ginseng products. In conclusion, the scientific studies on amendment scheme of ginsenoside content standard regulation of red ginseng product are very important to fortify quality control.

Since the major important factors limiting plant growth and crop productivity are environmental stresses, of which low temperature is the most serious. It has been well known that many physiological processes are alterant in response to the environmental stress. With regard to the relationship between plant hormones and the regulation of chilling tolerance in rice seedlings, the major physiological roles of plant hormones: abscisic acid, ethylene and polyamines are evaluated and discussed in this paper. Rice seedlings were grown in culture solution to examine the effect of such plant hormones on physiological characters related to chilling tolerance and also to compare the different responses among tested cultivars. Intact seedlings about 14 day-old were chilled at conditions of 5$^{\circ}C$ and 80% relative humidity for various period. Cis-(＋)-ABA content was measured by the indirect ELISA technique. Polyamine content and ethylene production in leaves were determined by means of HPLC and GC respectively. Chilling damage of seedlings was evaluated by electrolyte leakage, TTC viability assay or servival test. Our experiment results described here demonstrated the physiological functions of ABA, ethylene, and polyamines related to the regulation of chilling tolerance in rice seedlings. Levels of cis-(＋)-ABA in leaves or xylem sap of rice seedlings increased rapidly in response to 5$^{\circ}C$ treatment. The tolerant cultivars had significant higher level of endogenous ABA than the sensitive ones. The ($\pm$)-ABA pretreatment for 48 h increased the chilling tolerance of the sensitive indica cultivar. One possible function of abscisic acid is the adjustment of plants to avoid chilling-induced water stress. Accumulation of proline and other compatible solutes is assumed to be another factor in the prevention of chilling injuies by abscisic acid. In addition, the expression of ABA-responsive gene is reported in some plants and may be involving in the acclimation to low temperature. Ethylene and its immediate precusor, 1-amincyclopropane-1-carboxylic acid(ACC) increased significantly after 5$^{\circ}C$ treatment. The activity of ACC synthase which converts S-adenosylmethionine (SAM) to ACC enhanced earlier than the increase of ethylene and ACC. Low temperature increased ACC synthase activity, whereas prolonged chilling treatment damaged the conversion of ACC to ethylene. It was shown that application of Ethphon was beneficial to recovering from chilling injury in rice seedlings. However, the physiological functions of chilling-induced ethylene are still unclear. Polyamines are thought to be a potential plant hormone and may be involving in the regulation of chilling response. Results indicated that chilling treatment induced a remarkable increase of polyamines, especially putrescine content in rice seedlings. The relative higher putrescine content was found in chilling-tolerant cultivar and the maximal level of enhanced putrescine in shoot of chilling cultivar(TNG. 67) was about 8 folds of controls at two days after chilling. The accumulation of polyamines may protect membrane structure or buffer ionic imbalance from chilling damage. Stress physiology is a rapidly expanding field. Plant growth regulators that improve tolerance to low temperature may affect stress protein production. The molecular or gene approaches will help us to elucidate the functions of plant hormones related to the regulation of chilling tolerance in plants in the near future.

This study aims to analyze the social and legal status of Internet personal broadcasting in Korea and propose the direction of personal broadcasting regulation based on overseas regulatory laws and the media characteristics of Internet broadcasting. The influence of Internet personal broadcasting has increasing, and social and legal problems such as pornography and fake news have also growing. In the absence of legal regulations on personal broadcasting on the Internet, academia is also discussing relevant legislation and policies at a general level of analysis. In addition, the current study argues that new legislative research is needed to respond to the rapidly changing media environment and to cope with the newly introduced Internet broadcasting content and platforms. The findings suggest that freedom of expression is a significant value, yet obscene materials for minors should be thoroughly regulated, and that internet personal broadcasting should be regulated to the minimum extent through self-regulation guidelines through cooperation between councils and related agencies or businesses. The significance of the current study indicates that it proposed the practical and concrete laws for the improvement of the quality of Internet personal broadcasting content, the establishment of new broadcasting policies for fair and diverse content development, and the efficient and fair regulation of personal broadcasting content.

This study aimed to clarify relationships between the westernization of military uniform systems and changes in the textile import industry during the Eulmi reforms of clothing regulation. For the goal, the study investigated the content and features of that had been enacted under the Eulmi reforms. It also examined the status of the textile import industry at the time, especially in relation to outer garments such as jackets or Eui, trousers or Go, and overcoats. Moreover, this study inspected how the above westernization changed the textile import industry. More specifically, the research analyzed the content of based on articles from the then state newsletter or 『Gwanbo』, and the then cabinet meeting or Euijeongbu's proceedings or 『Euiju』. Concerning the textile import industry, this study looked into relevant descriptions and trade statistics from 『KOPEИ(Hankukji)』, and analyzed changes in that industry in connection with the introduction of Western military uniform systems. As a result, this study found that increased imports of cotton fabrics during the Eulmi reforms of clothing regulation was correlated with surging demand for shirt or lining materials and increase in the use of Myeonyung following military uniform westernization. Similarly, an increase in silk fabric imports was an outcome of increased demand for lining materials. Also, the import growth of woolen fabrics was seemingly attributed to the use of Heuknasa and Heukyung as basic materials of military uniforms. Thus, military uniforms began to be made of fabrics, which hadn't been used before in the wake of westernization. This development brought changes in the textile import industry, which is supported by textile import statistics of the time. In conclusion, the westernization of military uniform systems under the Eulmi reforms of clothing regulation was a significant factor that changed the industry.

Social Network Service(SNS), which are an emerging form of political architecture, have been a political means to promote civic engagement and shape pubic opinions on social issues. Along with the influence of SNSs, the governmental control on the dissemination of information over SNSs has increased more and more. It would be ideal if the autonomous governance regulates SNSs which facilitate the networks of the dispersed people. It is the fact, though, that compulsory regulations under which the government controls impose policy and legal restrictions on political expressions. The current study addresses expressive and participatory nature embedded in technological characteristics of SNSs and discusses the problems of content regulations of political expression over SNSs. First of all, it is analyzed that light touch regulation or light touch monitoring should be applied to regulating content on SNSs, particularly political expressions. Constitutional Court proclaimed that legal restrictions on the Internet could infringe basic rights of the people and thus under unambiguous standards, the Doctrine of Clear and Present Danger should be applied to its content. Second, it is found that clarifying the definition of illegality in the application of legal restrictions is necessary to minimize the excessive misleading. Third, it is required that Korea Communications Standards Commission under the government control needs to change in determining the scope of illegal information. In a domestic level, there needs to be safeguards for the protection of the self-regulatory organization such as KISO to guarantee voluntary and autonomous regulatory practices.

With the rapid development of AI technology, ChatGPT and other AI content creation tools are becoming common, and users are becoming curious and adopting them. These tools, unlike search engines, generate results based on user prompts, which puts them at risk of inaccuracy or plagiarism. This allows unethical users to create inappropriate content and poses greater educational and corporate data security concerns. AI content detection is needed and AI-generated text needs to be identified to address misinformation and trust issues. Along with the positive use of AI tools, monitoring and regulation of their ethical use is essential. When detecting content created by AI with an AI content detection tool, it can be used efficiently by using the appropriate tool depending on the usage environment and purpose. In this paper, we collect data on AI content detection tools and compare and analyze the functions and characteristics of AI content detection tools to help meet these needs.

Purpose: In this paper, we have dealt with problems and the improvement proposals of FTC (FAIR TRADE COMMISSION) report which insist on relaxed entry regulation for an optical shop. Methods: We analyzed each content of the FTC (FAIR TRADE COMMISSION) report which argue relaxed entry regulation for an optical shop. Results: At present, the supply of optician and optical shop are already saturated, the overseas cases cited would not be in accord with our reality. The reform of policy must take precedence in order to carry out the policy. A delicate balancing act is needed in order to satisfy both the government's and optician's needs. Conclusions: At this point, it is premature to carry out the relaxed entry regulation, this policy should be looked from a long-term point of view.

This study investigates, first, whether the extent of corporate social and environmental responsibility disclosure (CSERD) differs between 2010 and 2014; second, whether government regulation affects the extent of CSERD; and, third, whether the CSERD is valued by investors. Content analysis method was used to extract 466 companies' annual reports to measure the extent of social and environmental responsibility disclosure based on the Global Reporting Initiative (GRI) checklist. Independent sample t-test and multivariate regression analysis were also conducted to test the differences of the extent of CSERD as well as determinants and consequence of CSERD. Our results show that the extent of CSERD in 2014 is 21.60 percent higher than in 2010 (13.39 percent). Government regulation has a significant effect on the extent of CSERD. This study also finds that market values positively CSER information disclosed by company. Given that government regulation has a positive impact, however, the findings of this study suggests that the extent of CSERD is still low. To enhance CSERD, government should continuously encourage companies to abide by the regulations as mandated. This study provides a more comprehensive insights of CSRED practices from an emerging country and the effect of government regulation in enhancing CSERD.
