The expansion of the online market is expected to change the purchasing environment. The purpose of this study is to examine the difference in the moderating effect of each characteristic on perceived quality and purchase intention according to the group according to product involvement and purchaser age. The first step is to identify the characteristics of online information sources and social media platforms through a literature review. Next, when perceived quality affects purchase intention, we verify the moderating effect according to the characteristics of online information sources and social media platforms. The moderating effect is verified at the stage by dividing it into a group according to product involvement and a group according to age. The following results were confirmed throughout the study: First, perceived quality significantly affects purchase intention. Second, in the relationship between perceived quality and purchase intention, the influence of the moderating effect is different depending on the high-involvement product and the low-involvement product. Third, it was confirmed that there was a difference in the moderating effect of online information sources and social media platforms in the relationship between perceived quality and purchase intention according to age. This study intends to increase consumers' purchase intentions by identifying specific age groups and product groups of involvement and establishing strategies suitable for the characteristics of online information sources and social media platforms.

Background: In this study, the bleaching effect and surface damage of two types of over-the-counter home tooth bleaching agents were explored using an in vitro study of bleaching agents applied to bovine teeth specimens for 14 days. Methods: Domestic over-the-counter home tooth bleaching agents of gel and patch form that shared common active ingredients and manufacturers were selected and tested. The experiment specimens were made using composite resin with bovine tooth samples and then measured the initial microhardness. Specimens were then divided into a Gel group and a Patch group and underwent bleaching treatment once a day for two weeks for 30 to 60 minutes (recommended) or 7 hours. All specimens were coffee-stained prior to bleaching. The bleaching effect was measured using a spectrophotometer and surface damage was measured using a microhardness meter. Results: The difference in color following the bleaching procedure was positive in both the Gel and Patch group, although there were no statistically significant differences in bleaching effect between groups. There was no significant difference in bleaching effect based on duration. The microhardness test revealed that both the Gel group and the Patch group had surface damage after bleaching. The greatest surface damage was found in the Patch group that had undergone a 7-hour bleaching treatment, although the differences were not statistically significant. Conclusion: The bleaching effect of the home tooth bleaching agent was visible to the naked eye. However, longer applications than recommended did not result in greater bleaching, unlike consumers' expectations, and instead increased the chance of enamel damage. As such, there is a need for consumers to be alert and adhere to recommendations provided by each company.

The purpose of this study was to examine the effect of decentering and self-silencing in a relationship between socially prescribed perfectionism and social anxiety. We predicted self-silencing would function as a mediator in this relationship, and that decentering would moderate this mediation effect. To investigate this aim, three hundred seven university students were surveyed. All variables showed statistically significant correlations, and there was no statistically significant difference in the moderating effect of decentering in the relationship between socially prescribed perfectionism and social anxiety. Conversely, this study showed that there was a significant difference in the moderating effect of decentering in the relationship between self-silencing and social anxiety. In addition, socially prescribed perfectionism affected social anxiety through self-silencing, and decentering moderated the mediating effect of self-silencing. Implications and potential follow-up studies are discussed.

This study analyzed the effect of consumer psychological mechanism through ESG activities based on the importance of ESG in the market environment. With regards to this, 252 copies of survey data were collected subjecting consumers, and the hypothesis of this study was verified using Smart PLS 3.0 and SPSS 25.0. According to the results of data analysis, the results revealed that (1) Society and governance had a positive effect on psychological distance among ESG factors. (2) Psychological distance had a positive effect on purchase intention. (3) There was a difference in the effect of ESG activities and psychological distance according to the level of product involvement, but there was no difference in the effect of psychological distance on purchase intention. ESG is important from a consumer perspective through this study. And it was also confirmed that consumer perspective was different according to the level of involvement. Although previous research has mainly focused on the investor perspective, this study was analysed on ESG activities and consumer behavioral intentions. Therefore, it is expected to lay the foundation from a marketing perspective on ESG for subsequent researchers.

There are so many studies on perceived risk and purchasing intention. But the results of those studies were inconsistent; some studies showed the positive effect of perceived risk on purchasing intention; others showed the negative effect. This research supposed that the inconsistence of studies resulted from the difference of group innovativeness and set up research hypotheses : among users from the lower innovativeness group, perceived risk has a negative effect on purchasing intention, but from the higher group, perceived risk has a positive effect on purchasing intention. We compared Internet shopping mall users of South Korea representing low innovativeness with those of China representing high innovativeness. The results provided that among South Korean users, perceived risk had the statistically insignificant negative effect on purchasing intention, but among Chinese users, it had the statistically significant positive effect on purchasing intention. Additionally, this study found that perceived risk influenced users' fun which in turn influenced purchasing intention.

This study aims to clarify disfluency loci in a neurogenic stuttering group and to examine how the characteristics are different from a developmental stuttering group. For the study, spoken language samples were collected from 11 adults with developmental stuttering and 11 adults with neurogenic stuttering in the course of speaking tasks including reading, monologue and conversation. Using the collected samples, disfluency characteristics of the two groups were to be investigated by analyzing adaptation effect, consistency effect and frequency of disfluency occurrence according to word position, which are related to the occurrence loci of disfluency. Results of this study were as follows: First, while the neurogenic stuttering group did not show any adaptation effect, the developmental stuttering group showed the adaptation effect that the percent of disfluency word reducing as they read the same materials repeatedly. Second, there was no meaningful difference of consistency effect between the two stuttering groups. Third, the neurogenic stuttering group showed more disfluency frequency in final sounds among the word position compared to the developmental stuttering group.
