In this paper, we propose a web-based content syndication system in which users can easily choose Internet protocol television (IPTV) contents. This system generates personalized content guide to provide a list of IPTV contents with respect to users' interests and statistics information of their online social community. For this, IPTV contents and relevant metadata are collected from various sources and transformed. Then, the service and content metadata are processed by user metadata including audience measurement and community metadata. The metadata flows are separated from content flows of transport network. The implementation of IPTV content syndication system demonstrates how to arrange IPTV contents efficiently from content providers to the end user's screen. We also show that the user metadata including online community information are important for the system's performance and the user's satisfaction.

The rapid development of smartphone technologies have resulted in the evolution of mobile botnets. The implications of botnets have inspired attention from the academia and the industry alike, which includes vendors, investors, hackers, and researcher community. Above all, the capability of botnets is uncovered through a wide range of malicious activities, such as distributed denial of service (DDoS), theft of business information, remote access, online or click fraud, phishing, malware distribution, spam emails, and building mobile devices for the illegitimate exchange of information and materials. In this study, we investigate mobile botnet attacks by exploring attack vectors and subsequently present a well-defined thematic taxonomy. By identifying the significant parameters from the taxonomy, we compared the effects of existing mobile botnets on commercial platforms as well as open source mobile operating system platforms. The parameters for review include mobile botnet architecture, platform, target audience, vulnerabilities or loopholes, operational impact, and detection approaches. In relation to our findings, research challenges are then presented in this domain.

Although the development of digital technology and network has brought great convenience in modern lives, amongst the aggravated complexity in the contemporary society, modern minds who have failed to create genuine relationships undergo a sense of alienation and solitude that may appear as a type of social pathology called cellular-phone addiction. Also, while the emergence of the information age seemingly brings about benefits including diverse acquisition regarding knowledge and broader communication, underneath exists side effects involving leakage of private information. Especially, being excessively addicted to relationship network may induce one to become insensitive towards leakage of private information without recognizing, and thereby instigating yet another social problem. Media art is very practical in terms of suggesting a critical perspective concerning social phenomena and elevating them into a work of art by rendering them artistically. Particularly, when social problems of the modern days are expressed through digital technology, media art provides the audience with a foundation that will enable them to sympathize without hostility. This dissertation calls attention to the contemporary problems regarding cellular-phone addiction and possible hazards of information leakage based on media art, while at the same time proposing the production process of a media art work that attempts to raise awareness and sympathy on such social issues.

In this paper, we present an approach for detecting slide transitions in lecture videos by introducing the spatio-temporal residual networks. Given a lecture video which records the digital slides, the speaker, and the audience by multiple cameras, our goal is to find keyframes where slide content changes. Since temporal dependency among video frames is important for detecting slide changes, 3D Convolutional Networks has been regarded as an efficient approach to learn the spatio-temporal features in videos. However, 3D ConvNet will cost much training time and need lots of memory. Hence, we utilize ResNet to ease the training of network, which is easy to optimize. Consequently, we present a novel ConvNet architecture based on 3D ConvNet and ResNet for slide transition detection in lecture videos. Experimental results show that the proposed novel ConvNet architecture achieves the better accuracy than other slide progression detection approaches.

This study investigated the television (TV) content viewers' behavior influenced by online communication at the choice of new TV series on a terrestrial streaming platform. For exploring the impact of the anchoring effect on the TV content consumption, this study analyzed the correlation between the first episode's TV ratings and the data of online comments or reactions. These data were potential audiences' communication, which were generated on the online article three weeks before the first broadcasting began. To avoid the crucial influence by external factors, such as season and social issue, the test was done with eight (8) TV series which have same genre (drama), similar core audience targeting (20-49's women), similar broadcasting period (Jun-Oct 2016), same scheduling (10.00 to 11.00 pm, weekdays) and aired on terrestrial TV platforms. This research found that not only the amount of comments and reactions, but also the attitude about the comments created before broadcasting, positively influence the audiences' decision-making behavior for new TV content choices. This investigation contributes to the literature on media economics and management by exploring the media content users' consuming behavior with behavioral economics perspectives (anchoring effect) and making a first step for finding a new effect on the media content consumption.

This study sought to examine the effectiveness of mobile applications, which have recently increased persuasion effects by stimulating consumer experiences. In particular, to determine how content for public interest affects users' attitudes and beliefs, we selected interactivity and public interest as characteristics of mobile applications and examined their relationship. One of the actual applications was selected for research and the reactions of subjects who experienced it were investigated. As a result, the interactivity and public interest of mobile applications were found to have a direct and indirect influence on content attitude and beliefs, and it was confirmed that content attitude can affect beliefs. These research results show that cognitive structure can be influenced by reinforcing the audience's attitude toward content.

In the cyber space represented by Sns, the problem of cyber verbal violence, which sends slander messages such as abusive messages through chats, bulletin boards, malicious comments, and messages, is getting worse. Leveraging the power of cyberspace's anonymity, people can't hesitate to say what they can't say in the real world. In extreme cases, cyber verbal violence can lead to the death of a person. This paper focuses on the creation of media content that helps to inform and prevent the seriousness of cyber verbal violence prevalent on the Internet through interactive art. The nature of Interact art goes beyond the work and the audience to the people in the relationship between the work and the participants, allowing participants to directly and indirectly feel the seriousness of cyber verbal viol.

Due to social distancing caused by COVID 19, music concerts have not been allowed at home and abroad, and it is not known when overseas concerts will be able to resume unless the pandemics calm down, even if they are available. Meanwhile, people consume much more content through online services such as Netflix and YouTube than before. Under these circumstances, the music industry expects the virtual livestreamed performance to restore sluggish live performances again and bring about a digital renaissance. It also leads to the issue of reestablishing a copyright system regarding a livestreamed performance and of preparing a new rate of royalty standards for the use of works in OTT. In addition, a multi-territorial licensing of r ights in musical works is necessary to resolve copyright issues efficiently by applying the same term s to all countries from where the audience comes. In this paper, I examine the legal nature and the decision of copyright fees of performances as an integral part of the music industry.

This study aims to understand the determinants and effects of SNS photo sharing on festival satisfaction among teenage festivalgoers, to derive strategies that festival organizers could employ to maintain long-term relationships with their audience. In this paper, we followed the festival attribute and SNS photo sharing behavior approaches for developing measurement constructs, by investigating previous related studies. Statistical analyses revealed that festival attributes positively impact consumer perceptions of festival value, which in turn influences SNS photo sharing behavior and festival satisfaction. In addition, SNS photo sharing behavior has a significant mediation effect on the process. Moreover, the differing intensities of SNS usage among the festivalgoers resulted in consumers presenting significantly different SNS photo sharing behavior. Our findings offer insights for marketers in the festival business who are interested in gaining a better understanding of the behavior of teenage festivalgoers.

As the contemporary public consensus prefers individuality to classical things, they have gotten sick of the universality and pursue fashion anew. As a result the new concept of artistic value delivers a shock to ordinary and traditional images. The bizarreness culture of fashion contains two extremes, horror and humor. which make people uneasy but amused by sensuous descriptions. Bizarre things captivate the audience regardless of the violent stimuli. The conversion of aesthetic consciousness is brought accordingly by horror and humor. In this paper, It is discussed that the concept of history of bizarreness and the social effect from its phenomena in current fashion are expressed through the two methods above. The bizarreness phenomena in current fashion is shown as a new hybrid type which has been recreated and came out of the internet. This phenomena has caused abnormal results and ironically mixed products, what was once directness, violence and disgust, are on the other hand enjoyment and amusement. A widening field, the bizarreness phenomenon, as an important implication in which can completely change the current trend, will be on track as a crucial concept representing contemporary cultures.
