Train to Busan(2016) and Seoul Station(2016) contain trans-media properties in terms of the expansion of 'possible worlds' from the original story, and show the cultural and economic potential of the domestic trans-media contents with industrial systems added to the artist's competence of Dir. Yeon Shang-ho, an animator and film director. But they also have limits of the lack of continuity in time and characters between each media, various derived contents and suitable marketing strategy. For the development of Korean trans-media contents, it is necessary to extend the range of contents, find changes in production time and style, and improve the distribution environment to encourage a user to integrate contents from each platforms.

Antimicrobial powder was made by exchanging silver ion on calcined oyster shell. On the purpose of application to water clarifier, bail-type media mixed with antimicrobial powder and $0{\sim}30%$ white kaoline were made. The sterilization effect, pore size distribution and zeta potential was tested to indicate the condition for the media of water clarifier. From these tests, it was confirmed that this media have an excellent sterilization power on $G^-\;and\;G^+$ germs. As the concentration of the exchanged silver ion increased, the surface charge density of the anions on the surface of the media also increased. The surface pore size decreased with the concentration of silver ion and 20% more white kaoline ratio. Consequently, mixing ratio of white kaoline would appear to indicate the optimun condition as media have sterilization power.

This paper proposes a media key distribution scheme for lawful interception in secured VoIP systems. A problem of the current US or EU standards for lawful interception is that they do not provide a mechanism for collecting keys used for encrypting media streams between two end points. In the proposed scheme, dual encryption was applied on the media keys using two shared secrets: one between the ISP AAA server and user agent, and the other between the TSP registrar and user agent. Only the lawful agency with court warrant can collect both keys from the service providers. This scheme can still provide a privacy by preventing the misusage of the keys by the service providers.

Purpose - The purpose of this study is to investigate the relationship among narcissism, usage motives, usage behaviors, satisfaction with and continuance intention to use fashion social media. Research design, data, methodology - A questionnaire survey was used to collect data after conducting a pilot test. Based on the reliability test of the preliminary questionnaire used for the pilot test, the questionnaire was revised. The final questionnaires were administered to 238 fashion social media users and 216 were used for the data analysis. To assess the validity of these measures, exploratory factor analysis and the confirmatory factor analysis were performed. Structural equation modeling analysis were employed for data analysis. Results - Five factors of the usage motivation of fashion social media were extracted: information-seeking, relationship-seeking, practicality-seeking, enjoyment-seeking and self-expression motives. The statistical analysis confirmed the influence of the narcissism tendency on all of the usage motives of fashion social media, three of the fashion social media usage motives influencing information diffusion behavior, and the influence of the information diffusion behavior on users' satisfaction and continuance intention to use fashion social media. Narcissism exerted the highest influences on self-expression motive followed by information-seeking, enjoyment-seeking, relationship-seeking and practicality-seeking motives in order. Factors affecting fashion information diffusion behaviors are practicality-seeking motive, self-expression motive, and relationship-seeking motive. The greater the diffusion of information, the higher the satisfaction with using fashion social media. The consumers with higher satisfaction intended to use fashion social media and share information more frequently. Conclusions - The results indicate that narcissism is an important factor in fashion social media usage motivation. The main motives for narcissistic people to spread information is for the practical purpose at the most, and then to express their personality and style, and to build relationship with others. The satisfaction through active information sharing behaviors seems to play a key role to lead high continuance intention of fashion social media. These implies that marketing strategies to satisfy consumers' narcissism and motives to use social media, and to stimulate the information diffusion behaviors can be used to meet their needs for higher satisfaction with fashion social media.

The dynamic capabilities of social media are changing the nature of contemporary news by allowing users to communicate and create content, deliver and share newsworthy information, and consume news. News organizations engage with social media because this computer-mediated tool provides an alternative platform for delivering news and connecting with global audiences. This role of social media is conceptualized as its complementarity. However, when mass user-generated-content is constantly shared with other users, more users are attracted to indulge in news-seeking activities on social media. This phenomenon potentially fulfills users' news requirements on social media, which is contrary to what news companies envisioned when they began engaging with social media. This dichotomous role of social media, providing complementarity and showing the potential for becoming a superior news medium, is conceptualized as its competing-complementarity. This paper offers preliminary evidence of competing-complementarity by analyzing the news consumption of individuals. Such consumption is explained through the theoretical perspective of punctuated equilibrium by conceptualizing news consumption as a deep structure radically impacted by a disruptive technology. Although social media benefit news organizations, its competing potential poses serious challenges to their monopolistic controls on news production, distribution, readership, and revenue generation.

This study examines the relationship between social media marketing and brand loyalty through brand trust. Respondents were drawn from customers of McDonald's, Malang City, East Java Province, Indonesia. For this study, 130 questionnaires were distributed and data were analyzed using the Structure Equation Model (SEM) version 22 of the AMOS (Analysis of Moment Structure) application. The results showed that social media marketing had an impact on increasing McDonald's brand trust and brand loyalty. Brand trust influences brand loyalty and brand trust can mediate the influence of social media marketing on McDonald's brand loyalty. The findings prove that brand trust can mediate the effect of social media marketing on customer loyalty to McDonald's brand. These results can be explained by the fact that marketing strategies through social media marketing, such as making it easy for customers to get information related to McDonald's on social media, can contribute to customer trust and that trust is formed because McDonald's always pays attention to the quality of the products offered. Brand trust can mediate the influence of social media marketing on customer loyalty to McDonald's brand. This means that information related to McDonald's on social media is proportional to the quality of the product offered.
