In this study, based on the general reasoning that the higher the resolution of the HMD, the greater the presence and immersion of the audience and the greater the presence experience, the difference in the presence experience according to the resolution of the virtual reality device is verified empirically Presence effect. To do this, 300 college students were included in the population, and VR simulations of the Oculus store were conducted using HMD and mobile devices with different resolutions (HD, FHD, WQHD) as stimuli. As a result, there was a significant difference in the presence experience of the audience according to the resolution of the mobile device attached to the virtual reality HMD, and the presence effect had a significant influence on the awakening. On the other hand, no significant influence was found in the effect of emotion. Therefore, we can prove a general reasoning hypothesis that the higher the resolution of the virtual reality device, the greater the presence experience of the audience. However, since the confounding effect and the impression are contradictory in the presence effect side, additional experiments research is required.

We proposed a video summarization algorithm based on an ERP (Event Related Potentials)-based topic relevance model, a MMR (Maximal Marginal Relevance), and discriminant analysis to generate a semantically meaningful video skim. We then conducted implicit and explicit evaluations to evaluate our proposed ERP/MMR-based method. The results showed that in the implicit and explicit evaluations, the average scores of the ERP / MMR methods were statistically higher than the average score of the SBD (Shot Boundary Detection) method used as a competitive baseline, respectively. However, there was no statistically significant difference between the average score of ERP/MMR (${\lambda}=0.6$) method and that of ERP/MMR (${\lambda}=1.0$) method in both assessments.

This study seeks to derive game design elements that turn out game streaming-friendly through the analysis of Internet game streaming. To this end, this study surveyed previous studies on the motivation of watching internet game broadcasting and simplified the motivations to 'Expertise' and 'Amusement', the goal that game streaming should aim for, and divided streamer's streaming types into 'Reviewer', 'Master', 'Entertainer' and 'Acrobat' by those two options. Based on the categories, this study analyzed game streaming videos of various genres and confirmed that both the number of videos and the number of views by the streaming type were the highest in the 'Acrobat' group. In addition, the analysis shows that and revealed different figures by the type although they belong to the similar genre. By comparing and analyzing the systems and content elements of the two games, this study identified 's advantages in three points-Fortune, Setup Time, Control View- and finally suggested some guidelines for streaming-friendly game planning.

The increase in number of streaming platforms and contents thereof, owing to an advancement of cloud environment, has triggered the rapid proliferation of illegally replicated contents as well as legal contents. This necessitates the development of technology capable of discriminating the copyright infringement of various contents. The Korea Copyright Protection Agency operates a video content demonstration system using AI, but it has limitations on distortions such as resolution changes. In this paper, we propose the powerful mechanism using skeleton, which is resistant against distorted video contents and capable of discriminating copyright infringement of platforms streaming illegal video contents. The proposed mechanism exploits the calculation of Hamming distance to the original video by converting collected data into binary ones for the efficient calculation. As a result of the experiment, the proposed mechanism have demonstrated the discrimination of illegally replicated video contents with an accuracy of 94.79% and average magnitude of 215KB.

We are able to watch international multimedia anytime and anywhere, if we have the devices to connect Internet. Netflix and Youtube are the most massive and the most visited streaming platforms in the world. So If audiences are not familiar with the exotic culture such as behaviors, contexts, sarcasm, history and the current issues, It would happen a consequence that they entirely have to rely on subtitles in order to get inform. This research hereby aims to compare Korean transcriptions of the same movies streamed by the two selected platforms(Netflix and Youtube). As a result, good translation is that translators should use appropriate omissions and detailed explanations in limited time and space so that audience can concentrate on the vedio. If translators study the work in depth and spend enough time working on it, the quality of translation will definitely increase. Finally, this study contributed to the revitalization of the video translation market, which is still in the past, through the misinterpretation of videos produced at a low unit price and with minimal time without guidelines for video translation.

Objectives: This study aims to investigate the mediating effect of social support on the relationship between the viewing of sensational videos of idol stars through the mass media and the sexual openness of adolescents. Methods: This study used the 'Study on countermeasures against sexual commodification of adolescents through mass media in the smart era' conducted by the 'Korea Youth Policy Institute' in 2014 for the entire country as the main data. Variables consisted of socio-demographic characteristics of study subjects, video viewing, social support, and sexual openness. For data analysis, SPSS ver 23.0 program was used. Results: As a result of comparing the averages, male students (20.40) had higher sexual openness than female students (18.67), and high school students (20.27) had higher sexual openness than middle school students (18.05) at school level. By grade level, sexual openness increased from the first year of middle school (17.47) to the third year of high school (20.82) (p<0.001). In order to verify the mediating effect of video viewing on the effect of adolescent social support on sexual openness, 3-step mediated regression analysis and Sobel test were conducted. As a result, video viewing had a significant effect on sexual openness through social support (p<0.001). Conclusion: Rather than obscuring the environment of mass media unconditionally, creating an atmosphere according to the tendency of realistic social support and reinforcing emotional education will help prevent the adverse effects of reckless sexualization of adolescents.

One More Pumpkin won the grand prize at the 2023 Dubai International AI Film Festival, and new possibilities were also opened through the International AI and Metaverse Film Festival (GAMFF), which was held for the first time in Korea. Generative works began to stand out in earnest, with 527 diverse works from 42 countries at home and abroad using AI and metaverse technology submitted to this contest. AI is being used in a variety of fields, including the creation and implementation of digital characters through combination with VFX, improving the efficiency of video production, and managing the overall video production process. This contributes to saving human and material resources required for production and significantly improving the quality of produced videos. However, generative AI also has ambiguity in copyright attribution, ethical issues inherent in the learned dataset, and technical limitations that fall short of the level of human emotion and creativity. Accordingly, this study suggests implications at the level of production, screening, and use, as generative AI may have an impact in more areas in the future.

This paper makes a comparative analysis of themes, appeals, and aims of TV public service advertisements through 927 advertisements from China and South Korea. The study found that there is an obvious difference between China and Korea TV public service advertisements : (1) China TV public service advertisements pay more attention to public morals, while advertisements of South Korea focus on national fusion ; (2) In the way of appeal, different from China's rational demands, South Korea is based on emotional appeals ; (3) The aim of Chinese public service advertisements is for public but South Korea's target is for individuals. Thus, although both China and South Korea are Asian countries, their TV public service advertisements are obvious different. So it is necessary to analyze different situations of the two countries when China and South Korea focus on the same theme of publicity.
