The purpose of this study was to examine the influence of variables of TAM, user characteristics variables, and perceived risk variables on the intention to use mobile payment. Through the combination of characteristics of mobile payment, this study also investigated the effect of various independent variables on the intention to use mobile payment including the moderating effect of self-construal. To verify hypotheses of this study, the hierarchical regression analysis based on responses from 188 undergraduate and graduate students was conducted. The significant findings of this study were as follows: TAM variables, user characteristics variables and perceived risk variables had positive influence on the intention to use mobile payment. Self-construal was found to moderate the effect of the perceived usefulness, perceived ease of use and subjective norm. This study may provide important implications for both academicians and practitioners.

The purpose of this study is to examine a structural relationship among mobile self-efficacy, subjective norm, perceived usefulness, perceived ease of use and behavioral intention of mobile web service using technology acceptance model (TAM). 144 cyber university students enrolled in a course with mobile web service participated for this study. The result revealed that 1) mobile self-efficacy (${\beta}$ = .43, p<.05), subjective norm (${\beta}$ = .30, p<.05), perceived ease of use (${\beta}$ = .25, p<.05) had a direct effect on perceived usefulness. Second, mobile self-efficacy (${\beta}$ = .36, p<.05), subjective norm (${\beta}$ = .44, p<.05) had a direct effect on perceived ease of use. Third, perceived usefulness (${\beta}$ = .94, p<.05) had a direct effect on behavioral intention of mobile web service. However, perceived ease of use did not have a direct effect on behavioral intention of mobile web service significantly. Results of this study emphasize the role of an extended TAM including mobile self-efficacy and subjective norm in a mobile web service course at a cyber university.

Despite the development of technology and the increase in the spread of smart speakers, user satisfaction keeps decreasing due to conversational errors. This study aims to examine the effect of the self-repair strategy on user experience in the context of conversational agents of smart speakers. Scenarios were designed based on error situations, and participants were divided into two groups by task criticality. The results revealed that the agent's self-repair strategy has a negative effect on trust and perceived ease of use compared with performance without error. It also influenced adoption intention through interaction with task criticality. This study is significant in that it empirically investigated the effects of the self-repair strategy and the user experience factors related to the actual acceptance of the self-repair strategy.

In this study, We examined the dual path model in which entitlement rage and sexual dominance on the one of two pathway, sexual permissiveness and sexual objectification on another pathway mediated the relation between narcissism and sexual aggression. In addition, it was investigated whether alcohol use and rape myths acceptance have moderating effects in the pathways from sexual dominance and sexual objectification to sexual aggression on our path model. Data from 368 male college students in four university in Chungcheong province were analyzed using structural equation modeling. Results in structural equation modeling exhibited that narcissism affected sexual aggression through mediating effects of entitlement rage and sexual dominance, and through mediating effects of sexual permissiveness and sexual objectification. Furthermore, alcohol use and rape myths acceptance only moderated the relation between sexual dominance and sexual aggression on our model. We discussed the meaning of results and the implications for further study.

Focusing upon the post-adoption stage of IS, this study reasoned that IS users' personality is one of major influencing factors of continuous IS usage intention and empirically examined how the degree of continuous IS usage intention is variable according to the IS users' personality types classified based on MBTI(Myers Briggs Type Indicator). In order to validate the research model and hypotheses, this study made a field survey of 330 IS users and statistically analysed response data. The results of empirical analyses showed that the intent of continuous IS usage was affected by self-efficacy of IS; and self-efficacy by self-leadership of IS; and self-leadership by IS user' personality type and expectation confirmation. That is, it was found that IS users' personality type and three intervening variables(expectation confirmation, self-leadership and self-efficacy) were significant predictors of the intent of continuous IS usage. This study is thought to be contributive to providing the theoretical basis of finding IS success factors in the post-adoption stage and the practical guideline for effective personnel management relevant to IS implementation.

This study empirically examined the effect of married women's self-awareness on the acceptance of extra-marital relationships and the mediating effects of individuals' criticism of television's drama about infidelity. The data was obtained by conducting a survey of married women (304 persons) and was analyzed based on the Structural Equal Model (SEM). The notable findings are as follows. First, the respondents are generally less receptive to extramarital relationships. Of the total respondents, 46.7% do not accept extramarital relations. 43.8% of the respondents showed an unclear position on extra-marital relationships, and about 10% of respondents showed an accepting position on extramarital affairs. This suggests that extramarital relationships can emerge as a real issue that is important for married women. Second, self-awareness does not directly affect married women's acceptance of extramarital affairs, however, 'self-awareness' proved to have a significant effect on 'acceptance to extramarital relationships' by using 'criticism' as a full mediation effect for affair-themed TV dramas. The effects of critical thinking and the judgment of married women on the content of TV dramas containing adultery has been confirmed to be a very important aspect of married women's understanding of extramarital relationships. Some practical and political implications are discussed based on this study's findings.

As one of Virtual Reality devices, HMD(Head-Mounted Device) helps users to experience an extended actual environment by providing them with virtual environment flexibly through the device. HMD considers user experience as importance as well as technical factors. Therefore, this study intended to analyze how the factors such as information quality, enjoyment, self-efficacy can have influence on the adoption of VR device using the extended technology acceptance model. The results showed that information quality and enjoyment have significant influences on perceived ease of use and usefulness. Self-efficacy only affect perceived ease of use. In addition, perceived ease of use and usefulness have influences on intention to use.

This study investigated the antecedents of VR(virtual reality) headsets acceptance and the causal relationships among self-efficacy, content diversity, the perceived usefulness, the perceived easy of use, the perceived playfulness and the adoption intention. We collected 238 survey responses and formed structural equation modeling with AMOS 23.0. The results of the analysis can be summarized as follows. The diversity of contents and self-efficacy had significant effects on perceived usefulness, perceived ease of use and perceived enjoyment, thus increasing the intention of acceptance. Perceived usefulness, perceived ease of use and perceived enjoyment had significant effects on the intention of acceptance. Perceived ease of use indirectly had an effect through increasing perceived enjoyment. The price did not affect the adoption intention and marketing communication increased the intention of acceptance. The results are expected to provide useful information to the companies related to VR.
