Based on the secondary data of the 2018 news media audience conducted by the Korean Press Foundation, this study examines how the credibility of news on web portals and from news media outlets affects the types of web portal usage. The web portal usage was categorized into the two types: paying attention to news edited by the web portals and paying attention to news media outlets. These were named "portal site centered" and "news media outlet centered," respectively. This study found that the credibility of news from the web portals showed positive relationships with both portal site centered and news media outlet centered. The credibility of news from news media outlets had statistically significant relationships with the two types of web portal usage, but it differed depending on the audiences' preferences toward news media outlets. In other words, the credibility of news from news media outlets that are usually preferred or frequently used showed a positive relationship with the portal site centered, but has a negative relationship with the news media outlet centered. On the other hand, the credibility of news from news media outlets that are not preferred or not frequently used had a negative relationship with the portal site centered, but had a positive relationship with the news media outlet centered.

The purpose of the study is to investigate the effects of direction of comments about online reviews and the credibility of web sites on brand attitudes toward restaurants. Also, the study compared two study results using Korean and Chinese on-line users to assess the feasibility of the application of on-line marketing developed in Korea to Chinese internet user contexts. The results show that the credibility of web sites and the direction of comments influence the brand attitude as hypothesized. Overall, the results from two country consumer groups are similar. However, there are unique results including the significant interaction effects between the direction of comments and the credibility of web sites only for Chinese on-line users on the brand evaluation tasks and for Korean on-line users on the purchase intention. The cultural value might cause these different results across the nations.

A book review is one of the most important sources of information which provide the descriptive and evaluative contents about books. Reviews have great influence on consumer behavior because they are believed to be more reliable than information provided by sellers. Readers who read a book review includes information about book decide whether they will buy or not. This study examines customer attitude change by book reviews with regarding to different type of information sources(experts and prior customers) and different directions of messages. We address the following research questions: (1) Can positive book reviews with credibility have a positive impact on acceptance of books? (2) Can negative book reviews with credibility have a negative impact on acceptance of books? The results shows that a credibility is an essential factor for affecting customers' mind. When positive book reviews were written, both expert and customer opinions have a positive impact on acceptance of customers. Given negative book reviews of experts, trustworthiness is more important than expertise. However, a objectivity of customer's reviews is more important.

This study investigated consumer perceptions of information provided in a fashion Instagram. This study examined the differences between information provided in Instagram by brand vs consumers. A pilot test was conducted to develop stimuli and a brand selection in the main study. Participants were randomly assigned to one of two stimuli manipulated by information providers, and examined the perceived credibility, usefulness, and enjoyment of information as well as brand attachment and purchase intention. We gathered and analyzed a total of 200 data. The findings of the study showed that respondents perceived significantly greater usefulness and purchase intention of images uploaded by consumers compared to the fashion brand. Credibility and enjoyment were significant factors to enhance brand attachment; in addition, usefulness, credibility, and enjoyment were significant factors to increase purchase intention. The findings of the study suggest academic and marketing implications.

Credibility theory is one of important theories in actuarial science to produce proper insurance premium. In this paper, new partial credibilities are proposed and introduced with widely accepted credibility theories such as rule of relative exposure volume, square root rule, B$\ddot{u}$hlmann credibility and B$\ddot{u}$hlmann-Straub credibility. Also, with credibilities estimated by current and newly suggested, the performance of the accuracy for estimating the risk is compared through real data analysis and we show that the newly suggested methods are improving the performance by reducing the error.

Purpose: This study validated the influential relations between the effects of emergency care quality, credibility of 119 emergency medical technicians (119 EMTs), and perceived usefulness and attitude of emergency care, focusing on the moderating effect of protectors' characteristics (education, experience, age, and recognition of patient severity). Methods: This study was based on elaboration likelihood and technology acceptance models. In total, 172 protectors with experience in utilizing prehospital service were surveyed from April 1 to July 31, 2011. Results: The results showed that the emergency care quality and the credibility of 119 EMTs were the main determinants of the perceived usefulness and attitude of emergency care, irrespective of the protector's characteristics (p <.001). In addition, the findings showed that the protector's intention of emergency care had a moderating role. The impact of the quality of emergency care on its perceived usefulness was greater for high-level protectors (p <.001). By contrast, the impact of the credibility of 119 EMTs on the perceived usefulness of emergency care was greater for low-level protectors (p <.001). Conclusion: The protectors' characteristics have different influences on the relations between the effects of emergency care quality, the 119 EMT credibility, and the perceived usefulness and attitude of emergency care.

Sustainability is a significant change that fashion industry has undergone. Marketers and brands are looking for guidance in green advertising to most effectively motivate consumers to purchase sustainable fashion products. This study aims to reveal environmental and cultural sustainability claims on message credibility and purchase intention regarding product trendiness. We performed mediation and moderation analyses, using a 2 (sustainability message: environmental and cultural) × 2 (product design: classic vs. trendy) between-subjects experimental design. The PROCESS MACRO was used for the analysis. Results indicate that environmental claim must appear credible to consumers to motivate them to purchase a product. On the other hand, cultural claim, with and without credibility, affected consumer's purchase intention. Moreover, cultural claim and trendy design together influenced message credibility and purchase intention, showing a moderated mediation effect. The study indicates that brands should broaden their perspective regarding sustainability by considering cultural factors when providing sustainability claims. Environmental claim should be clear and transparent to avoid green skepticism. Also, it is important to focus on product's design aspect: making trendy designs. It is difficult to change consumer behavior based only on sustainability value. Thus, brands must coney their consideration of design trends. Theoretical and managerial implications also are discussed.

Liu[Fuzzy Optimization and Decision Making, 2(2003), 87-100] proved that convergence in credibility does not imply convergence a.s. and convergence in mean does not imply convergence a.s. by giving counter-examples. But these examples are not true. In this note, we prove that convergence in credibility implies convergence a.s. and convergence in mean implies convergence a.s.
