As multimedia content technology developed, there are many cases that service contents are being provided in many different ways in the cloud-based media service system. A DRM is a technology that can enhance the copyright of the digital content by providing right information. It is available on a single platform and has a problem that the additional cost when the platform is changing. In this paper, we propose a media service system based on cloud computing. It can be used on multiple platforms at the same time by applying a number of DRM for digital contents, and allows use of a new authentication for another platform without any additional cost.

소셜미디어인 동영상콘텐츠 플랫폼은 높은 몰입도와 이용 편이성 그리고 제약이 낮은 제작 환경으로 다양한 콘텐츠 생산 수단으로 활용되고 있다. 하지만 기존 소셜미디어 관련 연구들은 플랫폼 유형이 따른 차이에도 불구하고 기존의 정보속성과의 차이를 살펴본 연구가 미흡하였다. 이에 본 연구에서는 기존 미디어와 소셜미디어 정보속성에 따른 영향 관계를 살펴보고자 한다. 213명의 동영상콘텐츠 사용자들을 대상으로 설문을 실시하여 연구모형을 분석하였다. 연구모형 분석 결과 정보유희성, 정보적시성과 정보제공자 신뢰성은 정보유용성에 유의한 영향을 미쳤다. 하지만 정보생생함, 정보정확성, 정보중립성과 정보제공자의 전문성은 유의한 영향을 미치지 못했다. 본 연구를 통해 동영상콘텐츠와 기존 미디어나 소셜미디어와의 차이점을 알 수 있었으며, 신뢰성 있는 정보제공자가 적절한 시기에 즐거운 콘텐츠를 제공해야 함을 알 수 있었다. 또한 소셜미디어 성장세의 키플레이어인 동영상콘텐츠의 정보처리과정 이해를 통해 양질의 콘텐츠 제작에 많은 도움이 될 것으로 판단한다.

본 논의는 복합기제를 담은 미디어 텍스트의 확장 의미에 대한 인지화용적 의미 해석 이론을 토대로 대학생을 위한 의사소통 교육 및 한국어 연계 전공 교육자의 리터러시 교육의 연계가능성에 대해 논의된 질적 연구라 할 수 있다. 쌍방향적 의사소통 전략으로 활용된 미디어 콘텐츠 표현의 내포적 의미는 학습자 개개인의 인지환경에 따라 다각적인 해석으로 수용될 것이다. 그렇다면 콘텐츠 제작자가 의도한 일반적인 미디어 콘텐츠 의미 내용은 어떻게 수용되고 있는가. 이러한 의구심이 논의의 출발점이다. 필자는 문제해결을 위해 인지의미론의 실험화용적 방법론에 기대어, 인지언어학의 관련성 모델을 적용시켜 학습자의 창의적인 인지환경과 현시적 내용을 연결시켜 그 대비점을 모색하였다. 논의 결과 학습자 스스로 인지환경과 현시적 내용을 연결시킬 수 있는 주체성과 창의적 사고를 표현할 수 있는 기본 틀을 마련할 수 있었다. 특히 적극적이며 긍정적인 학습자들은 제작된 미디어 텍스트를 문제제기할 수 있는 토론의 능력과 텍스트에 내포된 의미의 타당성을 논증하기 위해 제 3의 대안을 제시하는 등 새로운 인지환경을 구축하는 직접적인 서술적 표현도 드러났다. 추후 복합기제가 담긴 미디어 텍스트는 현대 사회에서 다양한 매체를 통해 쉽게 이뤄지는 간접적이며 설득적인 의사소통 행위이기에 미디어 텍스트 제작자와 학습자의 신뢰적인 대화의 보편적 의사소통 원리가 존재해야 할 것이다

Social media have emerged as new communication channels between consumers and companies that generate a large volume of unstructured text data. This social media content, which contains consumers' opinions and interests, is recognized as valuable material from which businesses can mine useful information; consequently, many researchers have reported on opinion-mining frameworks, methods, techniques, and tools for business intelligence over various industries. These studies sometimes focused on how to use opinion mining in business fields or emphasized methods of analyzing content to achieve results that are more accurate. They also considered how to visualize the results to ensure easier understanding. However, we found that such approaches are often technically complex and insufficiently user-friendly to help with business decisions and planning. Therefore, in this study we attempt to formulate a more comprehensive and practical methodology to conduct social media opinion mining and apply our methodology to a case study of the oldest instant noodle product in Korea. We also present graphical tools and visualized outputs that include volume and sentiment graphs, time-series graphs, a topic word cloud, a heat map, and a valence tree map with a classification. Our resources are from public-domain social media content such as blogs, forum messages, and news articles that we analyze with natural language processing, statistics, and graphics packages in the freeware R project environment. We believe our methodology and visualization outputs can provide a practical and reliable guide for immediate use, not just in the food industry but other industries as well.

The "New Korean Wave" (Shin Hallyu) phenomenon, which is represented by the global popularity of BTS and director Bong Joon-ho's film "Parasite," is making the world excited. The influence of the Korean Wave is not only on politics, society, and culture, but it also has considerable economic ripple effects. We applied individual in-depth interviews with seven media and marketing experts in China to assess the changes in the impact of Korean cultural content (i.e., Hallyu content) and examine the possibility of marketing for Korean small and medium-sized enterprises (SMEs) products using Hallyu content. Considering its massive market potential, China is still an attractive target for Korean companies and is of even greater importance to SMEs, which are highly dependent on exports and lacking marketing budgets as well as a professional workforce. Korean businesses and the economy at large would get a real boost if they could penetrate the Chinese market by utilizing the strength of Hallyu content. Based on the results of the in-depth interviews, the conclusion of our study suggests the direction of advertising strategy on how Korean products can attract the minds of Chinese consumers by utilizing the Shin Hallyu. This research is a practical study that diagnoses the reality of the Korean Wave in China objectively and has excellent practical implications as it proposes methods of how SMEs should use Hallyu for their marketing strategies.

This thesis is a study of content development utilizing media outlets to date through digital humans. The trend of global content is that the video content industry, including the character business, is growing. Lil Michela, who was selected as one of the 25 most influential people on the Internet by Time magazine in 2018, Nasua, who appeared in a SK Telecom commercial, and Rosie, who appeared in a Shinhan Bank commercial, are representative. Digital humans, which are driving new content, are computer-generated human characters with various characteristics and are referred to as virtual humans, metahumans, and cyber humans. With the rise of the metaverse after COVID-19, digital humans are being utilized in various forms such as media and marketing as an element of visual content. In the form of media, we can see that the boundaries between the offline and digital worlds are converging, and in the form of marketing, we can see that digital humans connect consumers and products more naturally. In the form of interaction, it is possible to achieve two-way communication through various methods of operation, and through these factors, it is possible to go beyond behavioral communication in the form of memorialization to emotional communication through AI technology. What can be seen through these processes is that through the currently developing digital human production methods and AI functions, not only experts but also non-experts can create quality contents, and new directions of contents will appear, and contents that can provide immediate feedback by bringing consumers and creators closer together have been studied.

Web 2.0 has features produced the content through the user of the participation and share. The content production activities have became active since social network service appear. The social bookmark, one of social network service, is service that lets users to store useful content and share bookmarked contents between personal users. Unlike Internet search engines such as Google and Naver, the content stored on social bookmark is searched based on tag keyword information and unnecessary information can be excluded. Social bookmark can make users access to selected content. However, quick access to content that users want is difficult job because of the user of the participation and share. Our paper suggests a method recommending search word to be able to access quickly to content. A method is suggested by using Collaborative Filtering and Jaccard similarity coefficient. The performance of suggested system is verified with experiments that compare by 'Delicious' and "Feeltering' with our system.

This study analyzes 419 fake news items published in India, a fake-news-prone country, to identify the major themes, content types, and sources of social media fake news. The results show that fake news shared on social media has six major themes: health, religion, politics, crime, entertainment, and miscellaneous; eight types of content: text, photo, audio, and video, text & photo, text & video, photo & video, and text & photo & video; and two main sources: online sources and the mainstream media. Health-related fake news is more common only during a health crisis, whereas fake news related to religion and politics seems more prevalent, emerging from online media. Text & photo and text & video have three-fourths of the total share of fake news, and most of them are from online media: online media is the main source of fake news on social media as well. On the other hand, mainstream media mostly produces political fake news. This study, presenting some novel findings that may help researchers to understand and policymakers to control fake news on social media, invites more academic investigations of religious and political fake news in India. Two important limitations of this study are related to the data source and data collection period, which may have an impact on the results.

There has been an increase in the viewing of YouTube content among children and adolescents. This, coupled with the popularity of live-streamed video content such as mukbang, where viewers watch the host eat, has raised concerns about media addiction and the indiscriminate imitation of eating behavior. Therefore, there is a need for guidance on the appropriate behavior for viewing YouTube food content to promote healthy eating habits among children. In this study, we aimed to compare the patterns of the main caregivers and their children while viewing media and investigate the impact of viewing YouTube food content on the physical and mental health of the children. The findings suggest that active YouTube food content viewing by the main caregivers may reduce imitative behaviors due to passive media consumption by their children. This study provides valuable insights by comparing and analyzing the YouTube content viewing of the main caregivers and their children. The results can be used as a basis for the development of lifestyle-centered guidelines for children. However, it is important to note that this study was conducted during the coronavirus disease (COVID-19) pandemic when there was a significant increase in the use of media, which is limitation of the study.
