Corporate social media has been recently used in customer relationship management in many ways to improve product sales and company images. Not much research exists on corporate social media, Therefore, in this paper, we propose a research model to identify how corporate social media enhances corporate's CRM quality, resulting in forming customer's purchase intention. In detail, this paper is to examine how customer's perceived value of corporate social media influences CRM quality(CRM trust and CRM commitment), and then how CRM quality affects purchase intention. To this end, a total of 300 questionnaires were used from online panel respondents to test research hypothesis. The findings showed that service performance value and monetary value were major determinants of CRM trust, however, there was no association between brand integration value and CRM trust. In addition, the effects of service performance value and brand integration value on CRM commitment were found whereas monetary value had no effect on CRM commitment. The results also showed that CRM trust and CRM commitment played a critical role in forming of purchase intention. Theoretical and practical Implications are discussed.

Ultrasound has been found useful as a therapeutic modality for the reduction of muscular and tendinous spasm. It has also been utilized for pain and other pathologic conditions through the ability of soundwaves to introduce molecules of chemical substances through the skin by a process. Choice of the transmission medium is very important for effective ultrasound treatment in clinical field. The purpose of this study was to analyze the effects of various ultrasound conduction media in regard to ultrasound conductivity and degree of absorption, evaporation and of skin irritation. The media used in this study were Antiphlamine, Sacch lotion, Stereogel, Trastgel, Antiphlamine S lotion, and Mentholatum lotion that have been used in clinical medicine. The study revealed that Antiphlamine was not compatible with a good ultrasound transmitter. Other media excluding Antiphlamine were compatible with a good ultrasound conductor, but they had some drawback with their nature of higher absorption, evaporation and skin irritation. The medium that was prepared by mixing of Antiphlamine with Gel in 1 to 10 ratio was a good ultrasound transmitter and extents of absorption and evaporation and of skin irritation of it were less than the other media.

With the spread of social media and mobile devices, people spend more time on online than ever before. As more people participate in various online activities, much research has been conducted on how to make use of the time effectively and productively. In this paper, we propose two methods which can be used to extract highlights and make searchable media indexes using online social data. For highlight extraction, we collected the comments from the online baseball broadcasting website. We adopted peak-finding algorithm to analyze the frequency of comments uploaded on the comments section of the website. For each indexes, we collected postings from soap opera forums provided by a popular web service called DCInside. We extracted all the instances when a character's name is mentioned in postings users upload after watching TV, which can be used to create indexes when the character appears on screen for the given episode of the soap opera The evaluation results shows the possibility of the crowdsourcing-based media interaction for both highlight extraction and index building.

This article aims to explore the contribution of social media value to a company's financial performance in a digital environment economy since the awareness of companies and investors in the use of social media opens up new mechanisms for disseminating information. Quantitative method is used in this study with Multivariate Analysis of Variance as the analysis tool. The data used is secondary data gathered from Indonesia Stock Exchange (IDX) using 308 companies as samples. In the multivariate test, four kinds of multivariate significance tests were carried out, namely Pillai Trace, Wilk Lambda, Hotelling's Trace, and Roy's Largest Root. It was found that social media value has a small contribution in the difference of the level of profitability and the value of the company in Indonesia, but it doesn't have a contribution to the difference of the level of liquidity. The contribution was an implication of online Word of Mouth (WOM) motives which are interrelated with signal theory and as additional information for investors in relation to single-person decision theory. This study provides an insight into the importance of social media management considering that the world of digital economy will continue to develop, so companies in Indonesia need to take advantage of these opportunities.

Numerous people share their TV experience with other viewers on social media such as personal blogs and Twitter. It means that broadcast media, especially TV, affects the responses on social media. Moreover, the responses affect broadcast media ratings back. Social TV tried to use the relationship in marketing activities such as advertisement by analyzing the TV related social behavior. However, most of them used just the quantities of social media responses. This study analyzes the subjects of the responses on social media about specific TV dramas through topic modeling, and the relationship between the changes of popular topics and viewer ratings of the drama over specified periods. Five representative Korean dramas of 2014 were selected and Blog contents including viewer ratings about the dramas were collected from naver.com which is the representative portal in South Korea. The proposed analysis framework consists of three steps which are Blogs crawling, topic modeling, and topic trend analysis. We found some implications from the results of the topic trend analysis. Firstly, there were specific topics on dramas in social media. Secondly, the topics had some meaningful relationships with viewer ratings. Lastly, there were differences between the topics of dramas with higher viewer ratings and those with lower viewer ratings.

The aims of this study were three-fold; to analyze the trends of research on children's media, to anticipate any transitions in the direction of the research and finally to provide a guidance for future directions in the research. For this purpose, 55 research papers were chosen. The tool used for this analysis was that developed by Meyrowitz(1998; 1999), which classifies(1998, 1999) three main viewpoints towards media. Based on these three viewpoints, this study found that the most common category is 'media as a vessel.' Furthermore, it was verified that some studies in 'media as a vessel' have a tendency to be mixed with the notion of 'media as a language.' Subsequently, all the research papers in the category of 'media as a language' were subcategorized into 6 digital literacy competencies, in the manner proposed by Hobbs(2010). Consequently, the studies in the category of 'creation' were revealed to be the most common, and it was further confirmed that the research included in the categories of 'reflection' and 'social action' both begins to partially appear. Based on these results, this study speculates on a number of educational points supporting the development of media education in the digital era.

Large amount of sludge have been generating in the process of water and wastewater treatment in urban area, and it has been making many environmental problems. Currently almost of sludge is landfilled, and since sludge is difficult to handle and dehydrate, the permeated water from the filled-in ground contaminate the surrounding soil and groundwater which may cause serious environmental and sociological problems. The organic component in sludge can be almost removed through the heat treatment process, and the final product is called artificial soil or artificial media according to the temperature control. To produce artificial media using sludge, chabazite and lime were used as an additive, and the mixture of sludge & additives was thermally treated in the firing kiln at about 800~1, 100。C for about fifteen minutes. The physical and chemical characteristics of the produced artificial media were analyzed, and it showed that it can be used as an artificial media for plant production or soil conditioner for farmland. The concentrations of the toxic heavy metals in the artificial media were lower than the soil quality standard for farmland. The characteristics of produced artificial media, using the mixture of sludge and additives through the heat treatment, is similar to the natural chabazite and soil. The analyzed result of the mineral composition of artificial media showed that it has a characteristics similar to natural stable soil, so the produced artificial media may be applied to farmland or water culture without causing adverse effect. Therefore this study showed that the above process can be a feasible alternative for sludge treatment.
