Recently, plastic waste in Korea has been recognized as a critical issue due to an increase in massive production of plastics, difficulty in disposal of waste plastics, and public recognition of toxicity in micro-plastics, etc. To resolve those problems, the regulation to reduce plastics consumption may be primarily considered but, in this case, clarification should be made on the rationales and the action plans in the regulation for individual waste plastic items. Another problem is the small capital sizes of domestic recycling companies, which leads to poor R&D capacity, low recycling yields and thus lowering values of recycling items. This adversely affects consumers' perception. The R&D toward recycling technical progress should take into account the environmental friendliness and recyclability from the early product design stages. Certainly, this should be supported in governmental policy and public action plans. In addition, by referring to advanced policies of i.e. European Union, the recycling industry should be recognized as an opportunity toward new investment & employment. If necessary, the regulation of plastic consumption through a formal evaluation process such as Life Cycle Assessment (LCA) will also be helpful. The values of recycled plastics should be improved through the identification and elimination of harmful chemical substances potentially contained in the products.

Advertising, while providing a linkage between sales and consumption, helps promote rational consumption patterns by expanding the scope of information for consumers facing an ever-increasing array of consumption decisions. In so doing, advertising promotes competition among suppliers and sellers, thereby improving market transparency. Intrinsically, advertising can influence the instantaneous decisions made by consumers, and because of this peculiar feature of advertising, ensuring fair advertising practices is a policy issue of great importance. Concurrently, discerning whether the amount of advertising, which is determined by the profit motive of advertisers, is socially appropriate or whether this amount constitutes a waste of scarce resources is a necessary and indispensable consideration in establishing a public policy to respond to the mounting deluge of advertising. Although the Fair Trade Act and numerous other related laws are being enforced with regard to advertising, it may be difficult to say that a unified, practicable and logical basis for regulating the variegated and complex forms of advertising has been established. This paper examines the various theoretical arguments on the welfare effects of advertising as a rationale to justify regulation from the viewpoint of economics. In this manner, this paper helps define the essential nature of advertising and seeks to present a rational approach toward the regulation of advertising.

In this study, we developed tasks including cognitive scaffolding for students to explain scientific phenomena using valid evidences in science classroom and sought to investigate how tasks influence the development of small group scientific argumentation. Heterogeneous small groups in gender and achievement were organized in one classroom and the tasks were applied to the class. Students were asked to write down their own ideas, share individual ideas, and then choose the most plausible opinion in a group. One group was chosen for investigating the effect of tasks on the development of small group argumentation through the analysis of discourse transcripts of the group in 10 lessons, students' semi-structured interview, field note, and students' pre- and post argument tests. The discrepant argument examples were included in the tasks for students to refute an argument presenting evidences. Moreover, comparing opinion within the group and persuading others were included in the tasks to prompt small group argumentation. As a result, students' post-argument test grades were increased than pre-test grades, and they argued involving evidences and reasoning. The high level of arguments has appeared with high ratio of advanced utterances and lengthening of reasoning chain as lessons went on. Students had elaborate claims involving valid evidences and reasoning by reflective and critical thinking while discussing about the tasks. In addition, tasks which could have various warrants based on the data led to students' spontaneous participation. Therefore, this study has significance in understanding the context of developing small group argumentation, providing information about teaching and learning context prompting students to construct arguments in science inquiry lessons in middle school.

Visualization techniques are transformed into reliable representations through socio-technological processes which include the agreement on the instrument and the embodiment of practices in relevant scientific communities. Visual representations thus produced are justified by realistic and epistemic virtues in science. This paper analyzes different visual images presented in the scientific papers of two research groups who argue different theories about the mechanism of face perception. These two scientific groups use the same fMRI technology; yet, different experimental paradigms and visual stimuli change their hypotheses into distinct testable theories, which in turn lead to different evidences to support their own theories. Visual evidences are intermediate representations which lie between fMRI brain images and scientific theories, and theoretical models obtain the scientific value based on the consistency in the chain of visual representations. This study shows that representations in science tend to be good representations within the context of scientific communities. It will provide a chance to think of the value and limit of the scientific knowledge

We see the term in Tosan 12 songs and other poems by Leehwang. The term means 'Birds fly in the sky, Fish swim in the water.' It is important I think in that it is the point of contact between his poems and thought. There is a gap between original text of , [The way of mean (중용)] and Leehwang's understanding. It is same with Buddhism and Taoism as confucianism in the idea that we cannot describe the Ultimate into the human language. is the very confucian way of that. But Leewhang has the peculiar idea that it can't pass over the Moral state even though its meaning is over the human language.

Software agents reduce human involvement to a certain extent by automating routine tasks. However, most of agents have assisted with only a few steps in the multi-steps process of electronic transactions. In order to help users with the important steps in the electronic transactions, software agents need to persuade other parties to act in particular ways. While negotiations have many shapes and forms, this paper focuses on a particular class of negotiation, that is competitive business environment based negotiation. For negotiation with other parties in this contort, it is necessary for autonomous agents to consider environmental variables-the number of competitors, the number of negotiation parties, the maximum time by which they must finish their jobs, and user's preferences. Previous negotiation decision functions for the automated negotiation have used only time or the static numbs of negotiating parties as negotiation criteria, although competitive business environment should include potential competitors who can snatch negotiation parties away. This paper attempts to evaluate the performance of a negotiation decision function that considers the potential competitors in competitive market environment as well as that of a negotiation decision function that does not. For this evaluation, this study adopts the electronic marketplace as an application domain because many buyers and sellers compete for limited resources in the marketplace.

Given the context that users are actively using social media with multimedia embedded information, the purpose of this study is to demonstrate how images are used within Twitter messages, especially in influential and favorited messages. In order to achieve the purpose of this study, the top 200 influential and favorited messages with images were selected out of 1,589 tweets related to "Boston bombing" in April 2013. The characteristics of the message, image use, and user are analyzed and compared. Two phases of the analysis were conducted on three data sets containing the top 200 influential messages, top 200 favorited messages, and general messages. In the first phase, coding schemes have been developed for conducting three categorical analyses: (1) categorization of tweets, (2) categorization of image use, and (3) categorization of users. The three data sets were then coded using the coding schemes. In the second phase, comparison analyses were conducted among influential, favorited, and general tweets in terms of tweet type, image use, and user. While messages expressing opinion were found to be most favorited, the messages that shared information were recognized as most influential to users. On the other hand, as only four image uses - information dissemination, illustration, emotive/persuasive, and information processing - were found in this data set, the primary image use is likely to be data-driven rather than object-driven. From the perspective of users, the user types such as government, celebrity, and photo-sharing sites were found to be favorited and influential. An improved understanding of how users' image needs, in the context of social media, contribute to the body of knowledge of image needs. This study will also provide valuable insight into practical designs and implications of image retrieval systems or services.

Focusing on the information sender, message, channel, and receiver, the existing information theory deals with the noise, information contents, and probability of choice, which involve in the process of information transmission. In the current digital environment, besides simply conveying information itself through media, the important issue is how to efficiently convey information. Therefore, we need to analyze the theory in different perspective, and to research the Information redundancy for the methodology of information design. The redundancy causes the receiver to have attraction to the information and to reduce its contents due to its supplement and repetition. So it can play a role of efficient communication method. The concept of redundancy is applied to the communication of art such as literature, architecture, painting, and design to accomplish efficient communication. In order to get persuasive information design for the receiver's perspective we need to make use of this concept. The redundancy can be applied with the technical aspect of multimedia and Interaction, which add supplemental expression, or sort of event for the receiver's experience and memory. In the process of constructing information it can be applied with the structure of gaming redundancy, entropy, the accumulating communication code using entertaining feature, and storytelling methodology. The noise and entropy could be used for the means of making redundancy, not the obstacle to information. The redundancy gives the receiver attraction on the information and makes them have strong will of interpreting it so that the purpose of conveying information will be accomplished efficiently.

This study aims to provide guidelines for the activities of workplace health managers by identifying their excellent health promotion activities and motivations. For this, consent for the study was obtained from 21 workplace health managers who had worked at the same company for more than five years, and a semi-structured questionnaire was sent via email to collect and qualitatively analyze the data. As a result, 17 categories and three topics were drawn. The derived topics included a sense of reward and accomplishment as workplace health managers, difficulties encountered as workplace health managers, and how to solve the difficulties. The survey respondents answered that they feel a sense of reward and accomplishment when workers open their mind, change their daily life, express gratitude, and pioneer new fields. On the other hand, they feel difficulties with unpredictable health, changes in the organizational culture, secrecy of disease, and people who think their job is easy. As a way of overcoming such difficulties, the research subjects said that it is necessary to read the minds of workers, let them know by themselves, use existing programs, have the most difficult people on their side, and spread their achievements. The results of this study revealed that it is required for workplace health managers to develop professional skills and emphasize the importance of health management to the policy-makers and employees of their workplace by continuously reporting health management performance. In addition, they need to actively benchmark the success strategies of exemplary workplace health managers.

This paper intends to examine how North Korea has incited and persuaded its people by figuring out the structure regarding the meaning creation of its documentary film "Kim Jong-un, the Respected Comrade Supreme Commander, Giving On-site Guidance on the Grand Project of the People's Army" produced in 2015, which was North Korea's politically important year. The analysis results show that its narrative structure of the film took the form of an introduction, body, and conclusion to substantiate it obviously given theme. Its imaging techniques are geared towards uplifting the public's combat mentality and its sound contributes to achieving their adherence. In this regard, its film literature has the following meaning structure: first, the film takes the form of both film annals and the structure for the public to easily comprehend; second, the film clearly demonstrates its deep-rooted theme asking for the public to follow in the footsteps of the party's late father for its leadership; and third, the film also aims to establish the images of an always awake working leader by implanting and arranging the leader's diligence about his revolutionary activities in the documentary film. North Korea's documentary films serve as a weapon used for instigating revolution and construction. Given this, the producers of all documentary films have made sure to turn film literatures into the film literatures of the great leader. It was identified that under the social vision that the Kim Jong-un regime is a "socialist civilized country", he has tightened his grip on power in North Korea through the propaganda tool of film literatures.
