The purpose for this paper is to categorize and analyze the aesthetic characteristics of graphic factors in contemporary fashion design by media source. Focused on play-instinct visual expression in contemporary fashion design and adopted media source following the way of communication design. A variety of literatures and online sites for graphic factors in contemporary fashion was studied. The standard of media source is classified as graphic media-source: photography media-source, typography media-source, illustration media-source. With this standard, expressed ways are as followings. First, graphic media-source in play-instinct expressional fashion design is mostly borrowing existed character or using designer's brand logo. Second, photography media-source in play-instinct expressional fashion design is placed photograph of social issued people in front of shirt. Third, typography media-source in play-instinct expressional contemporary fashion design is mostly expressed social messages or designer's name in brand. Fourth, illustration media-source is the best way to express play-instinct visual expression. Based on these, aesthetic characteristics of graphic factor in contemporary fashion by media source are classified as three: social words, playfulness and information transference. Frequency ratio using media source per aesthetic characteristics is different and these are able to categorize expression way and image feature. In conclusion, expressional way of graphic factors in contemporary fashion design became diverse as social and cultural changing. Frequency of graphic factor use in contemporary fashion is increased than before. This paper suggested that fashion design is one of the way of communicating with people and should be analyzed graphic factors in contemporary fashion design.

Recently, media platforms such as YouTube and Twitch provide services that can generate personal revenue by utilizing media content produced by individuals. In this regard, interest in the copyright of media content is increasing. In particular, in the case of an audio source, competition for securing audio source copyright is fierce because it is an essential element for almost all media content production. In this paper, we propose a method to store the audio source and its signature using a blockchain and distributed storage system to verify the copyright of music content. To identify the possibility of extracting the audio signature of the audio source and to include it as blockchain transaction data, we implement the audio source and its signature file upload system based on the proposed scheme. In addition, we show the effectiveness of the proposed method through experiments on uploading and retrieving audio files and identify future improvements.

Social media has become a popular source of information around the world. Previous studies explored different trends of social media news consumption. However, no studies have focused on Bangladesh to date, where social media penetration is very high in recent years. To fill this gap, this research aimed to understand its popularity trends during the period. For that reason, this work analyzes 97.67 million page likes and 3.48 billion interaction data collected from nine Bangladeshi news media's Facebook pages between December 2016 to November 2020. The analysis shows that the growth rates of page likes and interaction rates declined during this period. It suggests that the media's Facebook pages are gradually losing their popularity among Facebook users, which may have two more interpretations: Facebook's aggregate appeal as a news source is decreasing to users, or Bangladeshi media's appeal is eroding to Facebook users. These findings challenge the previous results, i.e., Facebook's demand as a news source is increasing with time. We offer four explanations of the decreased popularity of Facebook's news: information overload, exposure to incidental news, users' selective exposure and different aims of using Facebook, and conflict between media agendas and users' interests. Some theoretical and practical significance of the results has been discussed as well.

이 연구의 목적은 소스 경쟁 과정에서 시민단체 소스가 정부 소스와 어떻게 경쟁하고 있으며, 언론보도에 어떠한 형태로 반영되는지 비교 분석해보는 것이다. 이와 함께 세부적인 영향 요인으로서 언론보도 이데올로기, 갈등 사안의 발전 단계가 어떻게 소스 간 경쟁에 영향을 미치는지 알아보았다. 설정한 연구문제에 답하기 위해 스크린쿼터를 분석의제로 삼고 언론보도, 스크린쿼터문화연대, 정부기관의 6년 3개월간 관련 문건을 내용 분석하였다. 연구 결과, 스크린쿼터와 관련한 언론보도에서 전반적으로 시민단체에 비해 정부의 중요 정의자 역할이 더 우세하다는 결론을 도출할 수 있다. 하지만 언론의 보도 이데올로기에 따라서 시민단체의 소스 역할이 증가되는 경향을 보이는 것으로 나타났으며, 스크린쿼터와 같은 사회적 논란이 많은 사건에서 시민단체의 목소리가 어느 정도 반영되고 있지만 그것이 아직 정부에 대한 소스 의존을 넘어설 정도는 아닌 것으로 드러났다. 한편 그러한 현상은 갈등이 심해질수록 뚜렷해지는 것으로 나타났다. 이는 지표 이론의 예상을 뒤엎는 것이다. 세부 속성을 통한 의존 정도를 살펴보면 '가공 현상'과 '증폭 현상' 등 소스 반영 형태의 다른 특징들이 나타나기도 했다. 이러한 결과를 바탕으로 '소스 경쟁 이론'을 향후 실증적으로 검증하기 위한 명제들을 제시했다.

This study aims to examine how the relationship with an information source affects people to perceive credibility of online information. We developed a conceptual framework that explained how people perceived information credibility when they were familiar with the information source and/or when the information source seemed credible. We then compared the models in two different contexts, namely, online review and social media sites, to examine differences. We surveyed 136 online social media users with their online shopping experiences. Among our eight hypotheses, three (H6: the personality similarity between an information provider and an information seeker enhances the perceived credibility of the former; H7: the credibility of an information provider produces a much stronger mediating effect in review sites than in social media sites; H8: the familiarity of an information seeker with an information provider produces a stronger mediating effect in social media sites than in review sites) are fully supported and four (H1: the credibility of an information provider has a positive influence on the perceived credibility of the online information; H2: the familiarity of an information seeker with an information provider has a positive influence on the perceived credibility of the online information; H3: the goal similarity between an information provider and an information seeker enhances the perceived familiarity of the latter with the former; H5: the personality similarity between an information provider and an information seeker enhances the perceived familiarity of the latter with the former) are partially supported. The hypothesis of H4: the goal similarity between an information provider and an information seeker enhances the perceived credibility of the former is rejected. The result confirms that credibility of information is strongly mediated by credibility of information source than familiarity with information source in online review sites and vice versa in social media sites.

Stormwater runoff from urban road area as non-point source has a tendency of including lots of pollutants at initial rain period. Recently, there are several cases of having installed treatment facilities for reducing pollution discharge from the impervious cover in urban area to prevent watershed environment from getting worse. The filtration type among non-point source treatment systems has been known as one of the most efficient system for treatment of non-point source pollutants. Therefore, various kinds of filter media such as expanded polypropylene(EPP), granular activated carbon, zeolite, perlite, illite, sand, gravel has been developed. This study was conducted to verify performance and hydraulic characteristics of filter media as measures for non-point source. The experiment was carried out to evaluate applicability and variation of 4 kind of most popular filter media(EPP, GAC, Zeolite, Perlite) in headloss with elapsed time and influent flow rate and to obtain data base that could be used to establish management plan for road runoff treatment. In experiment by tap water, it showed that EPP and perlite those are floatable materials showed stable operating performance and lower headloss than the others.
