Social media is one of the important marketing channels for companies, changing the way interacting with customers. Marketers attract participation from customers' in social media platforms by producing branded content, which helps them gain various marketing results such as brand awareness, web traffic, and sales. The number of the empirical studies on the effects of social media on marketing performance is still low although various success stories and studies have been published. In particular, IT companies are trying to attract users onto their websites with social media content and promotions; however, they regard the number of the visitors as a vanity metric, which has little effectiveness. The study examined the Effect of the site introduced via Facebook, a typical social medium, on customers' revisit. Precedent studies proved that revisit, one of forms of major visit for satisfactory results of a website, is suitable for analyzing the operational output on Facebook pages. The results of the study demonstrated that Facebook content has a positive impact on website inflows and revisits. Also, it turns out that the higher the average website visit depth reinforces the positive relationship between the rate of the inflow and that of the site revisit.

Purpose: More and more marketers use social media platforms to create and spread information called Marketer Generated Content (MGC) to inform consumers of products. MGC often embeds product purchase links, thus directing consumers to online distribution channels for online purchases. This study examined the effect of social media MGC on consumers' willingness to buy online in the anchor of consumers' perspective to answer the question of "how social media generated content support corporate online distribution". Research design, data, and methodology: According to the means-end-chain theory, we introduce perceived value and continuous following intention as chain mediators to explain the mechanism of MGC influence on consumers' online purchase intention and consider product type to discuss boundary conditions. Two experiments were designed to test hypothesizes. Results and Conclusion: First, emotional MGC (vs. informational MGC) has lower (higher) perceived utility (hedonic) value. Second, perceived value has a significant mediate role in the effect of MGC on continuous following intention. Third, perceived value and continuous following intention significantly and sequentially mediated the effect of MGC on online purchase intention. Through the sequential mediations of perceived utility value and continuous following intention, Informational MGC of search products significantly increase online purchase intentions. Another parallel sequential mediation, including perceived hedonic, emotional MGC of experience products, partially enhanced online purchase intentions. Finally, this study gives implications for how corporates can use social media MGC to promote product sales online.

It has been 10 years since KBS first broadcasted TV program for the purpose of expanding mutual criticism among Korean mass media. This study conducted a content analysis of KBS episodes for the last 10 years. Through the content analysis, this study explored what the program had showed us in the aspects of 'the subject of criticism', 'the ground of criticism', 'the attribution of criticism'. The content analysis could show meaningful results to the study of media criticism, because it not only provides a meta-analysis of the problems Korean mass media have had for the last 10 years but also examines the program has been consistent in the regard of criticism fairness. The result of this study showed that has pointed out the practices of unfairness, political bias and superficial and shallow reporting as the most critical problems the Korean mass media have. Also, the result showed that had not been consistent in the regards of 'the subject of criticism', 'the ground of criticism', 'the attribution of criticism'. While the program mostly focused on the problems of political bias and unfairness in the early stage, the focus of criticism moved to the problems of sensationalism and superficial reporting laster. This study discussed that the change of criticism might have a relation with the change of KBS governance.

The news media report the pledges of presidential candidates, which have important implications for political communication. This study is to investigate the difference between news coverage on the presidential candidate' s pledge and to discuss its implications. The sampled news from the two newspapers were analyzed for content analysis. Frequency analysis and Chi-square analysis are utilized with SPSS. As results, there was no difference in the tone of the article's headlines, but the difference of the tone between the article content was statistically significant. The results means that the media framing affect on the reader's perception. Follow - up study can be suggested a comparative study of past election candidates 'pledge reports, a network analysis for the news language, and a comparative analysis of newspaper coverage and broadcast coverage.

Effects of phosphorous (P) and methylglyoxal (MG) on the cell number, dry weight, chlorophyll content, photosynthetic and respiratory rate, phosphate uptake and protein content of green algae (Scenedesrnus obliquus) were studied. The algal cell number from the medium treated with 0.5-1.0 mM of MG at 1/2 P or 1/4 P concentration was significantly lower than those of algae treated :with full strength of phosphrous in medium. The inhibitory effect of MG on algal cell division was enhenced at low concentration of phosphorous in medium. At the beginning of logrithmic phase of algal growth, the mean dry weight of algae from the medium without MG-treatment in 1/2 P media was significantly higher than that of algae treated with MG. After logrithmic phase of growth cycle, the mean dry weight of algae from the medium with 1.0 mM of MG-treatment in 1/4 P media was significantly lower than that of algae treated with or without MG. At logrithmic phase of algal growth, there were significant differences in the chlorophyll content among all groups of tested algae with various concentrations of P and MG. At 15 days after inoculation, the mean chlorophyll content per algal cell from the media without MG-treatment in 1/2P was significantly higher than that of other cells from MG-treated media. The adverse effect of MG at concentration of 0.5-1.0mM in 1/2 and 1/4 P media on photosynthetic rate was observed. The mean photosynthetic rate of algal cell without P and MG treatment at 15 days after inoculation was significantly higher than that of MGtreated algae. After logarithmic phase, the algal cell treated with 0.5mM of MG with full strength of phosphorous showed significantly high respiratory rate than that of other cell groups. There were significant differences in mean phosphate uptake rate among all groups of Scenedesmus obliquus at logarithmic phase. At 12 days after inoculation, phosphate uptake rate per each algal cell from the basic media without MG and P treatment was rapidly reduced which shows early introduction to stationary phase.

N-screen is a promising technology to improve support for multimedia multicasting, content sharing, content mobility, media scalability, and seamless mobility. In this paper, the WiMedia distributed-MAC (D-MAC) protocol is adopted for development of a seamless N-screen wireless service. Furthermore, to provide a multi-hop, one source multi-use N-screen service through point to point streaming in a seamless D-MAC protocol, a dynamic multi-frame transmission technology is proposed. In this technology, a dynamic time slot allocation scheme and a multi-hop resource reservation scheme are combined. In the proposed dynamic time slot allocation scheme, two thresholds, a hard threshold and a soft threshold, are included to satisfy the power consumption and delay requirements. A multi-frame DRP reservation scheme is proposed to minimize end-to-end delay during the multi-hop transmissions between N-screen devices. The proposed dynamic multi-frame transmission scheme enhances N-screen performance in terms of the multi-hop link establishment success rate and link establishment time compared to the conventional WiMedia D-MAC system.

In this paper, a method to extract temperature effect information using the color temperatures of video scenes with mapping to temperature effects is proposed to author temperature effects of multiple sensorial media content automatically. An authoring tool to apply the proposed method is also introduced. The temperature effects generated by the proposed method are evaluated by a subjective test to measure the level of satisfaction. The mean opinion score results show that most of the test video sequences receive an average of approximately four points (in a five-point scale), indicating that test video sequences (with the temperature effects generated by the proposed method) enhance levels of satisfaction.
