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.

This study investigated differences in cosmetic buying behavior and personal characteristics between cosmetic involvement groups. Cosmetics buying behavior refers to reason for using cosmetics, use of information sources, selection criteria, place of purchase, use/non-use of cosmetics, purchase propensity, purchase frequency, purchase amount, and satisfaction with cosmetics. Personal characteristic contains pursuing image, age, residence area, job, and average household monthly income. Data was collected from 5-10 December 2016, from 308 females in their 20s using an internet survey. The analysis included descriptive statistics, t-tests, Mann-Whitney U tests, and chi-square tests. The respondents were divided into two groups (a high cosmetic involvement group and a low cosmetic involvement group) according to the degree of cosmetic involvement. The results of t-tests revealed significant differences between groups in terms of reasons for using cosmetics, use of information sources, selection criteria, purchase frequency, place of purchase, use/non-use of cosmetics, and satisfaction with cosmetics. The results of Mann-Whitney U tests highlighted a significant difference in purchase frequency between both groups. The results of chi-square tests indicated significant differences in purchase frequency, purchase amount, pursuing image, and average household monthly income. However, no significant differences were evident in terms of purchase propensity, age, job, and area of residence between groups.

This study aimed to identify the effects of sports participation motives, the involvement in choosing sportswear, and the satisfaction with/perceived importance of sportswear functionality, on customers' repurchase intentions. A total of 185 survey questionnaires were analyzed after surveying 200 female undergraduates in their 20s. The research results are as follows. First, the participation motives for sports were categorized as follows. A factor analysis conducted on 13 questions yielded 4 factors. Factor 1 included consideration about socializing and pleasure, factor 2 privileged ostentation, factor 3 was concerned with enhancing health, and factor 4 was about maintaining appearance. Second, the various effects of different sports participation motives, of the satisfaction with functionality, and of the involvement in buying sportswear on customers' repurchase intentions were analyzed. The intention to repurchase sportswear was considered as a dependent variable, while the motives for participating in sports, the satisfaction with functionality, and the level of involvement were treated as independent variables. A multiple regression analysis using these variables showed that the satisfaction with functionality and involvement in choosing sportswear had a significant impact on the intention to repurchase sportswear. Third, looking at how different participation motives for sports affected the importance of sportswear functionality, the motives related to socializing and pleasure and ostentation, the sub-factors in sports participation motives, significantly increased the importance of comfort. Motives related to enhancing health and maintaining appearance, on the other hand, were found to affect the importance of sports performance. Fourth, a MANOVA was performed to examine the difference in the importance of functionality between those consumers highly involved in sportswear-buying and those less involved. Those with a high level of involvement were found to prioritize sports performance over comfort. Those with a low level of involvement were shown to place a greater emphasis on comfort.
