The purpose of the present study is to examine how visitors of personal web sites evaluate self presentation styles. We hypothesized that visitors' gender, self construals, and self esteem would influence the evaluation (likeability and perceived competence) of the self presentation styles (bragging or positive presentation). The hypothesized models were tested with structural equation modeling. Gender differences among the constructs were also examined through latent mean analysis. The results revealed that females tended to have higher interdependent self construal than males. And the male and the female students showed higher likeability toward the self presentations of the other gender. Regarding perceived competence, women and men perceived the other gender more competent, and especially, women perceived men's bragging presentation more competent. Self construals and self esteem, however, did not show any significant effects, which were inconsistent with the results of the previous studies conducted with offline self presentation styles. One of the main implications of this study is that visitors' gender, among other things, is the most infueltial factor in perceiving and evaluating others' self presentation through personal web sites.

This study was to evaluate of the reliability and validity of the Risk Perception Survey - Diabetes Mellitus (RPS-DM) with Korean diabetes patients. A total of 183 patients participated in this study from December 4, 2014 to January 1, 2015 with self-reported questionnaires. The data was analyzed using exploratory factor analysis, cronbach's alpha, and item to total correlation. The factor structure of the instrument showed the cumulative variance of 45.1% in the factor analysis and a four-factor structure was found to be appropriate. The comparative site risk score matched with the RPS-DM in English except item 7, 8, and 12. The RPS-DM in Korean version has been found to be reliable and valid.

This study examined the potential mediating mechanisms underlying the association between peer victimization and school adjustment. 521 children in the fifth and sixth grades were recruited from primary schools in Korea. Peer nomination and self-reports were used to measure peer victimization, cognitive representations, and school avoidance. Academic achievement records were obtained from official school records. The findings indicated that peer victimization contributed to school avoidance and academic achievement by different pathways. The association between peer victimization and school avoidance was indirectly mediated by perceptions of the self and peers. In contrast, peer victimization was directly associated with academic achievement.

As smart phone market has been rapidly saturated, wearable devices have been emerging as a new growth power in the post smart phone era. This study aims to comprehend the influential factors of purchasing intention of product features(perceived usefulness, perceived ease of use) and individual characteristics(innovation, fashion leadership, self-efficacy, concern for health) of wrist wearable device. The result shows that fashion leadership and health concern among consumers' individuality, and perceived usefulness and perceived usability among product features are proved to be significant factors. This means that both usefulness and usability have significant impacts on purchase intention of wearable device and product development should be made to enhance user experience.

This study was conducted to identify the factors influencing toothbrushing behaviors of elementary school students by adding the variable of 'self-efficacy' to the behavioral model based on the theory of planned behavior. To collect the data for an analysis, the self-administered questionnaire was distributed to 443 students in 4th to 6th grades of elementary school placed in Inchon Metropolitan City. The statistical package of PASW 18.0 was employed for the analysis. Results of the analysis revealed that the toothbrushing intention was explained by the subjective norm (${\beta}=0.343$), the self-efficacy (${\beta}=0.171$), the perceived behavioral control (${\beta}=0.163$), and the attitude toward the tooth-brushing behavior (${\beta}=0.135$). The toothbrushing behavior was explained by the toothbrushing intention (${\beta}=0.355$) and the self-efficacy (${\beta}=0.113$). The synthesis of such results suggested that both parents and teachers in school who would be influential to students should guide elementary school students to be habituated to the right toothbrushing. Also it was estimated that the students should understand the importance of toothbrushing through proper oral health education, and they should also become confident in spontaneous toothbrushing by providing them with an environment that could help them practicing the toothbrushing easily.

The purpose of this study was a descriptive research that identified the levels of health-promoting behaviors, previous related behavior, perceived benefits/barriers, self-efficacy, and social support. In addition, it was to establish the relations among the variables, and determine the factors affecting the health-promoting behaviors. Study participants were 311 middle aged between 55-64 in urban areas, and the data were collected through self-reported structured questionnair. According to the results, the mean score for the levels of health-promoting behaviors of the late middle aged was 2.64. Also, among the variables related to health-promoting behaviors, perceived benefits were the highest score (30.7), and perceived barriers were the lowest one (2.08). Meaningful positive correlations were found among health-promoting behaviors and previous related behavior, social support, perceived benefits, and self-efficacy, but perceived barriers showed weakly negative correlations. In addition, the factors affecting health promoting behaviors were revealed in order as following: Previous health related behavior(${\beta}$=.35, p<.001), perceived benefits(${\beta}$=.32, p<.001), social support(${\beta}$=.28, p<.001), and life satisfaction(${\beta}$=.13, p<.001), and this model's explanatory power was 68.8%(F=166.71, p<.001). Based on the findings from the study, in order for the late middle aged to have a well-being old age, an health promoting education program including exercises and stress management should be provided to maintain and improve proper health promoting behaviors. The network with the same age groups also should be supported to share useful information and back up one another.

This study was conducted to investigate the factors influencing perceived father communication, emotional expressiveness and gender identity on self-efficacy of female nursing college students. Data were collected from 270 female nursing students in B city, from May 23, 2016 to May 27 and then analyzed by ANOVA, Pearson's correlation coefficient, and multiple regression using SPSS/WIN 21.0. The degree of self-efficacy among female nursing students was $3.21{\pm}0.38$. There were significant differences in self-efficacy with respect to academic status(F=5.13, p=.006), relationship with father(F=4.74, p=.001), academic grade(F=5.22, p=.006), and gender satisfaction (F=4.00, p=.004). There were positive correlations between self-efficacy and open communication(r=.30, p<.001), self-efficacy and positive emotional expressiveness(r=.37, p<.001), and self-efficacy and gender identity(r=.26, p<.001), while there were negative correlations between self-efficacy and close communication(r=-22, p<.001), and self-efficacy and negative emotional expressiveness(r=-.26, p<.001). Regression analysis showed 18.2% variance in female nursing student's self-efficacy in response to positive emotional expressiveness, negative emotional expressiveness, and gender identity. Overall, the results of this study indicate that it is necessary to identify various factors affecting and increasing self-efficacy of female nursing college students.

The purpose of this study is to investigate the structural relationships among frontline hotel employees' core-self evaluations (self-esteem, generalized self-evaluations, locus of control, and emotional stability) as personal resources, customer verbal aggression as a job stressor, and turnover intention as a job outcome. Data were gathered from a sample of frontline employees of 10 five-star hotels in Busan via self-administered questionnaires. A total number of 405 questionnaires were utilized. This study used structural equation modeling to verify the research model and hypotheses. As hypothesized, the results demonstrated that core-self evaluations reduced customer verbal aggression and turnover intention, and customer verbal aggression amplified turnover intention. Finally, practical implications were discussed in detail and limitations of the study and future research directions were also suggested.
