When people try to find restaurant information via search engine results, they look at posts not only from sites with solely restaurant reviews but also from sites with restaurant unrelated contents. This study aims to investigate whether relevance between post and blog type affects users' trust toward a review. This study also attempts to check if the above effects interact with age. We designed a restaurant review post for two different blogs: one featuring restaurant review and another that does not feature restaurant reviews. After our participants visited one restaurant review post, they answered our questionnaire. We conducted an online survey on 206 participants to test our research model. Results show that 1) the effect of relevance between post and blog type on message credibility, which is users' trust toward restaurant reviews, is not greater when posts are consistent with the theme of a blog. 2) Among users who are over 30 years old, relevance between post and blog type moderates the relationship between media skepticism, which is users' feeling of mistrust toward blog, and belief in expertise, that is, users' belief that the review post provides sufficient restaurant information. 3) Users' perceived value of the restaurant review post mediates the relationship between users' belief in the expertise in a post and users' intention to seek additional information.

Public opinion has dramatically shifted from positive to negative in Korea society especially since the IMF crisis. Such terms as 'aristocratic union', 'collectivism', 'damages on public interest' became a kind of conventional wisdom. Undoubtedly, media's representation has much to do with such a tantamount difference. This study thus attempts to understand the mechanism by analyzing media discourse related to labor strikes. For this purpose, this paper made a choice three cases including doctor-pharmacist dispute, general strike by truckers' solidarity, and Ssangyong Motor's strike. Total 217 editorial pieces of , and conceived to be a representative newspaper of ideological stance were analyzed. Research showed that while paying particular attention to demoralizing labor strikes, shed positive light on such disputes by articulating fundamental causes hampered by pro-capital policies along with anti-labor law enforcement. The believed to be relatively a neutral one showed ambivalent attitudes toward those cases. More favorable and inclusive reporting were found in accordance with policy shifts as well. Media's selective partisanship for the sake of private interests is firmly believed to downgrading credibility on Korean journalism. Also is fair, balanced and less biased reporting over socal disputes a vital part in crystallizing social consensus. In this consideration, the authors hoped this study to provide an opportunity to contemplate on what would be desirable journalistic values in modern democracy.

Electronic Commerce or e-commerce implies such an industry where goods and services are bought and sold over electronic systems. This is rapidly growing sectors in Bangladesh which influence local and international trade. Government of Bangladesh has also initiated quite a good number of measures for the expansion of e-commerce. However, low adoption of e-commerce is not uncommon in Bangladesh. The objective of this study is to determine the factors that influence the adoption of e-commerce services in Bangladesh. Extended version of Technology Acceptance Model (TAM) is envisaged as the theoretical backbone of the study. Reliability analysis using Cronbach's Alpha test indicates that the research model is internally consistent. The study reveals that 35 percent of respondents became interested in e-commerce services from advertisement on Internet or other electronic media. The findings of the study shows that all the four constructs, namely-Computer Self Efficacy, Perceived Credibility, Perceived Usefulness and Perceived Ease of Use have significant effect on the adoption of e-commerce. The study has also demonstrated that Perceived Usefulness appeared as the most important factor in describing user's adoption of e-commerce.

There have been reports in the media about some refineries that omit the refining process and deliver raw material for reasons of cost reduction, shortening of production time, etc. Also, in most RMC factories acceptance inspection is not conducted on account of issues with the proficiency of the equipment and cost issues; instead only scores are relied upon. Therefore this study sought to analyze the relation between the value of the density of FA actually delivered to RMC companies, attained with the Hydrometer method, and its fineness, to see whether the quality of FA can be evaluated statistically. Results led to the conclusion that there is a problem in terms of credibility in the fineness of FA shown on the test report. Upon analyzing the difference between the fineness of FA as measured using Blaine's air permeability method and its density of the Hydrometer method, the correlation was found to be satisfactory; therefore the possibility of a FA fineness quality evaluation could be proved as well.

In China, the usage of smart speaker is continuously increasing. In this study, it is aimed to research on the user experience of the Chinese smart speaker. Therefore, we did literature research followed with theoretical background of smart speaker, and did case study of worldwide popular smart speaker brands. On this basis, we conducted in-depth interview with 8 users who have experienced with the top-selling Chinese smart speaker product "Tmall Genie" and "Mi AI speaker". The interview is based on 7 principles named Honeycomb model, which created by Peter Morville. As a result, users' discomfort was found in the functional part and the usability part of the smart speaker. Furthermore, the users were highly unsatisfied with the smart speaker in the credibility part. Accordingly, Chinese smart speaker should consider the user experience aspects to complement functional and usability parts for user.

With the Covid-19(Corona Virus) spread all around the world, people are using this propaganda and the desperate need of the citizens to know the news about this mysterious virus by spreading fake news. Some Countries arrested people who spread fake news about this, and others made them pay a fine. And since Social Media has become a significant source of news, .there is a profound need to detect these fake news. The main aim of this research is to develop a web-based model using a combination of machine learning algorithms to detect fake news. The proposed model includes an advanced framework to identify tweets with fake news using Context Analysis; We assumed that Natural Language Processing(NLP) wouldn't be enough alone to make context analysis as Tweets are usually short and do not follow even the most straightforward syntactic rules, so we used Tweets Features as several retweets, several likes and tweet-length we also added statistical credibility analysis for Twitter users. The proposed algorithms are tested on four different benchmark datasets. And Finally, to get the best accuracy, we combined two of the best algorithms used SVM ( which is widely accepted as baseline classifier, especially with binary classification problems ) and Naive Base.

Today, newspapers and newsmagazines are using statistical graphics to provide information and highlight the essense of newspaper stories. When statistical graphics do not present meaningful information accurately, concisely, and in easy-to-understand language, the publication risks a loss of credibility with its readers. Too often newspapers and newsmagazine run faulty graphics. The surge in the use of statistical graphics have created new problems and challengers for editors and artists of newspapers and magazines. We summerize and study the misuse of statistical graphics by means of the research of newspaper and newsmagazine. Experiments were employed to explore the effects of the distorted graphs. This paper suggests the statistical rules for avoiding the pitfalls of statistical graphics and institutional solutions for reforming the knowledge of artists and readers about statistical graphics.

The illegal copy of Windows software is one of the problems, because Windows is the most popular operating system in the country. The illegal copy can be infringe a software copyright, and software birthmark is one of solutions which is protecting software copyright. Software birthmark is a technique to distinguish software piracy using feature information from software. The type of software birthmark can be differentiated between static birthmark and dynamic birthmark through an extraction method. Static birthmark and dynamic birthmark have strengths and weaknesses. In this paper, we propose similarity measurement technique using dynamic birthmark based on API, and we explain extraction process of dynamic birthmark. In addition, we have verified that the proposed similarity measurement technique meet resilience and credibility through experiment. Furthermore, we saw that proposed measurement technique better than existing measurement technique.
