With the emergence of SNS, TV, newspapers and radio, which are one-way communication media, have become less important. Therefore social networking enables social networking beyond the constraints of time and space, and communication and emotional communication required for social relations have emerged as a factor in the importance of social media. Social media, which is based on rapid connectivity and scalability, is an medium of expression that is advantageous for companies and consumers to communicate more easily than traditional advertising media. Advertising can form a consensus that consumers and companies can create an atmosphere of friendly conversation because of the social media that has the efficiency of communication. This study compares two ads. One is the advertisement of 'Bear and Hare', an animation of John Lewis department store in the UK, where a new form of advertising marketing strategy is fused with emotional storytelling and social media. The second is an advertisement of LG, 'I love you LG' to be. Social media should be remembered as a warm and loving company in the heart of customers through open communication with customers, rather than companies that pursue merit profits by using social media ads as a medium of emotional transmission to consumers. It is a study on useful advertising strategy that can pursue the sales of the company at the same time.

The purpose of this study is to investigate the impacts of Collaborative Problem solving for Character competency (CoProC) strategy on the practical character competency and collaborative problem solving competency in middle school. For this study, 49 seventh grade students (two classes) were selected for use applying the CoProC strategy (CoProC group) while 46 students (two classes) were used for traditional lecture and experimental class (comparative group). In the result, CoProC group showed a statistically significant result in practical character competency than the comparative group. In the sub items of the competency, the CoProC group showed result statistically significant in cooperation, communication, responsibility, and positive self-understanding than the comparative group. Analysis of the effect size of students' practical character competency showed that the CoProC group results showed more effective than the comparative group in terms of care, cooperation, communication, honesty, responsibility, positive self-understanding, and self-regulation. In addition, we investigated the effect of the CoProC strategy on collaborative problem solving competency. As a result, it showed a large effect in the total score of collaborative problem solving competency. Among the sub items of the competency, 'exploration and understanding of members' showed a small size of effect and 'Establishing and maintaining team organization' showed a medium size of effect. 'Communication' and 'self-reflection' showed a large effect. CoProC strategy embedded in Science subject could improve students' collaborative problem solving competency through the process of scientific communication in the scientific inquiry process.

This paper examines the situation and tasks of UK rail privatization, especially focusing on after the Hatfield rail accident. Earlier research which focused on the UK's Privatization had little knowledge of the explanations for recent changes. Moreover they had difficulty making a direct comparison between national rail and the privatized rail. Therefore we aye left without a good explanation which has a comprehensive perspective. I attempt to show the change in the rail privatization Process and its outcome, focusing on after the Hatfield rail accident. This Paper argues that the UK's vail privatization process has a regulatory framework which is too complicated with overlapping responsibilities that brought about inefficiency, increasing costs and a superficial safety regime. Especially the planning of rail and infrastructure maintenance did not come to play an appropriate role. However after 2000, the government took charge of setting the strategy for railways, and the Office of Rail Regulation covered safety performance and cost. explain that these changes present a good opportunity to solve the problem of passing the buck for poor performance. Through the analysis, I find that the passenger rail network is well-suited to deliver long distance business and commuters and that the subsidy from the government is decreasing. However, performance, for example punctuality and reliability. should be improved. Especially the Hatfield rail accident caused a reduction in the satisfaction of passengers. In future. the problems of rising costs and monopoly franchise system should be addressed.

Since the outbreak of COVID-19 in 2019, the pandemic has been prolonged. This study compares and analyzes the degree of social media usage, the information type of posts (infectious disease information, promote action, psychological communication), and the level of user engagement in conducting crisis communication by country. We conduct text analysis by collecting information on Facebook and YouTube posts from January 2020 to March 2021 of disease control and prevention agencies in Korea, US, UK, and EU. As a result, the use of social media in Korea and US is higher than of the UK and EU, and all four countries are using social media as a means to provide infectious disease information and to promote action. Although social media can be a means to reach the public psychologically, such as sympathy and respect, there are no posts of psychological communication type on social media in countries other than the US. User engagement with posts is highest in the promotion action type. This study can help define the importance and role of social media in establishing an infectious disease crisis communication strategy.

In this study, we developed an approach to better account for uncertainties in estimated contributions from fine particulate matter ($PM_{2.5}$) modeling. Our approach computes a Concentration Correction Factor (CCF) which is a ratio of observed concentrations to baseline model concentrations. We multiply modeled direct contribution estimates with CCF to obtain revised contributions. Overall, the modeling system showed reasonably good performance, correlation coefficient R of 0.82 and normalized mean bias of 2%, although the model underestimated some PM species concentrations. We also noticed that model biases vary seasonally. We compared contribution estimates of major source sectors before and after applying CCFs. We observed that different source sectors showed variable magnitudes of sensitivities to the CCF application. For example, the total primary $PM_{2.5}$ contribution was increased $2.4{\mu}g/m^3$ or 63% after the CCF application. Out of a $2.4{\mu}g/m^3$ increment, line sources and area source made up $1.3{\mu}g/m^3$ and $0.9{\mu}g/m^3$ which is 92% of the total contribution changes. We postulated two major reasons for variations in estimated contributions after the CCF application: (1) monthly variability of unadjusted contributions due to emission source characteristics and (2) physico-chemical differences in environmental conditions that emitted precursors undergo. Since emissions-to-$PM_{2.5}$ concentration conversion rate is an important piece of information to prioritize control strategy, we examined the effects of CCF application on the estimated conversion rates. We found that the application of CCFs can alter the rank of conversion efficiencies of source sectors. Finally, we discussed caveats of our current approach such as no consideration of ion neutralization which warrants further studies.

The Purpose of this study is to analyze an active discussion in North America about the issue of community archives governance which mainly focused on 'participatory archives' model and from it, draws implications for the present stage of domestic community archives development. Traditionally in the United States and Canada, local community archives have been built mostly by mainstream cultural institutions such as public archives, public libraries, museums, and historical societies as a part of comprehensive documentation of the society at large. At the same time, they have been processed and managed in accordance with the institution's collection development policy. As a result, most community archives in North America are characterized as top-down community archives model (in contrast with down-up model of 'independent' community archives as a part of grass roots movement in the UK). Recently, the community archives in North America with these characteristics try to overcome their limitations, which result in 'the others' of community archives, through governance, that is, community-institution partnership. Participatory archives model which assumes active community participation in all archives processes is being suggested by archival communities as the effective alternative of governance model of top-down community archives. This discussion of community archives governance suggests progressive direction for the present stage of domestic community archives, which has been built mostly by various mainstream cultural institutions and still has been stayed in 'about the community' stage. Particularly, community outreach strategies that participatory archives model concretely suggests are useful as a conceptual framework in building community archives based on community-institution partnership in reality.

As ICT convergence is progressing in all industrial fields and creating the global ecosystem of the supply chain is accelerating, supply chain risk related with cyber area are also increasing. In particular. the supply chain of ICT products is very complex in terms of technical and environmental factors to be managed, so it is vert difficult to transparently manage the entire life cycle. Accordingly, the US, UK, and EU, etc. are conducting and establishing cyber supply chainsecurity-related research and policies for ICT product supply chains. Korea also has the plan to establish management system to secure the supply chain of major ICT equipment as a task in the basic plan of the national cybersecurity strategy announced in 2019, but there is no concrete policy yet. So, In this paper, we review the cyber supply chain security management system in the United States and present a supplementary way to the National Information Security Manual in Korea from the perspective of cyber supply chain security. It is expected that this will serve as a reference material for cyber supply chain measures that can be introduced in domestic information security field.

Central Asian Countries had been independent in 1991 from USSR. Since then it have been increasing foreign trade and investment amount with outside countries including China, Japan, EU and South Korea. Korean enterprises and entities have endeavored to secure plentiful natural resources, oil and gas energy and expand the market share to exporting the consuming and industrial competitive goods and services for those countries. In the case of disputes of commercial transactions and investment, arbitration is regarded as a dispute resolution system which has been preferred in international transactions and investments by the business world. Since the collapse of the USSR, Central Asian Countries have worked to modernize its arbitration law and procedure to conform with international standard rules. Arbitral legislation in Central Asian countries is based on the Model Law as adopted in 1985. However, CIS's legislation systems of arbitration are not satisfied with the international standard in national laws and practices. That is the reason to consider for the specific parliament about arbitration for the dispute resolutions in the commercial transaction and investment between Korean enterprises and CIS. In this article, it is discuss problems and its alternatives in the dispute resolution about the commercial transaction and investment into Central Asian countries including the tendency to the increasing the trade volumes of goods and investment between South Korea and CIS. According to this article, South Korea consider the long term strategy followed the preferred economic relative partnership for business success on commercial transaction and investment with the Central Asian Countries.
