Purpose: The purpose of this study is to identify the mediating effects of self-esteem between social comparison orientation and social network service (SNS) addiction in university students. Methods: Descriptive cross-sectional survey design was employed. The data were statistically analyzed by using the descriptive and inferential statistics. Sobel test and Bootstrap method, and Kappa squared mediation effect size measure were used to identify the mediator's significance. A convenience sample of 195 subjects was recruited from two universities in Korea. Results: The mean age of the subjects was $22.58{\pm}1.81$. The subjects showed relatively high levels of SNS addiction with a mean score of $14.33{\pm}4.80$. The overall model significantly explained 37.0% of variances in the subjects' SNS addiction after controlling gender, age, grade, major, period of SNS using, time spent on SNS per day, and times accessed SNS per day. Of the predictors, time spent on SNS per day, social comparison orientation, and self-esteem were significantly associated with SNS addiction. Self-esteem was the mediator between social comparison orientation and SNS addiction. Conclusion: When developing strategies for preventing SNS addiction, interventions for reducing time spent on SNS per day, not having upward social comparison orientation, and improving the self-esteem should be considered. These findings might provide a theoretical basis for developing effective strategies for preventing SNS addiction in university students.

This paper describes facial component detection and skew correction algorithm for face recognition. We use a priori knowledge and models about isolated regions to detect eye location from the face image captured in natural office environments. The relations between human face components are represented by several rules. We adopt an edge detection algorithm using sobel mask and 8-connected labelling algorith using array pointers. A labeled image has many isolated components. initially, the eye size rules are used. Eye size rules are not affected much by irregular input image conditions. Eye size rules size, and limited in the ratio between gorizontal and vertical sizes. By the eye size rule, 2 ~ 16 candidate eye components can be detected. Next, candidate eye parirs are verified by the information of location and shape, and one eye pair location is decided using face models about eye and eyebrow. Once we extract eye regions, we connect the center points of the two eyes and calculate the angle between them. Then we rotate the face to compensate for the angle so that the two eyes on a horizontal line. We tested 120 input images form 40 people, and achieved 91.7% success rate using eye size rules and face model. The main reasons of the 8.3% failure are due to components adjacent to eyes such as eyebrows. To detect facial components from the failed images, we are developing a mouth region processing module.

The purpose of this paper is to examine the effect that Chinese tourists' perceptions of beauty products and their friendliness toward Korean culture have on beauty tourism, particularly on Chinese tourists' intent to purchase, re-purchase, and recommend beauty products. Between the 10th and 21st of June, 2016, a total of 277 questionnaires were distributed in Seoul, Busan, and Daegu using SPSS 21.0. Cronbach's ${\alpha}$ was undertaken to test the reliability of the questions and an analysis of the frequency, factors, t-test, and Sobel test used in the study. Korean beauty was derived from two factors: "product favorability" and "product excellence and credibility." Product favorability had a significant effect on the intent to purchase, as did participants' friendliness toward Korean culture. Re-purchases and the intent to recommend beauty products were also significantly affected. In the relationship between the perception of beauty products and the intent to purchase, the study revealed partial mediation effects of the participants' friendliness toward Korean culture on product favorability and complete mediation effects on product excellence and credibility. Friendliness toward Korean culture had partially mediated the effect that product favorability had on the intent to re-purchase and recommend. Tourists' friendliness toward Korean culture had complete mediation on the effect that product excellence and credibility had on the intent to re-purchase and recommend. According to the Gender Equality and Family Act, the difference between buying and selling beauty depends on the difference between purchase and intentions. Friendliness toward Korean culture has become an important variable thanks to product superiority and reliability.

Objectives: The purpose of the study was to investigate the influence of organizational communication satisfaction on the job satisfaction, organizational commitment, and turnover intention in the dental hygienists. Methods: A self-reported questionnaire was completed by 227 dental hygienists in Chungnam. The questionnaire consisted of 4 questions of general characteristics of the subjects, 8 questions of interpersonal stress, 12 questions of organizational communication satisfaction, 5 questions of job satisfaction, 5 questions of organizational commitment, and 5 questions of turnover intention. The four variables were measured by Likert 7 point scale. Data were analyzed using SPSS version 18.0 for frequency analysis, t test, one way ANOVA, Pearson's correlation coefficient, and stepwise regression analysis. Sobel test was used to verify the mediating effects. Results: The interpersonal stress was proportional to turnover intention and inversely proportional to the organizational communication satisfaction, job satisfaction, and organizational commitment(p<0.01). The organizational communication satisfaction was proportional to the job satisfaction and organizational commitment, and inversely proportional to turnover intention(p<0.01). The interpersonal stress had a meditating effect between organizational communication satisfaction, and job satisfaction. It also gave the mediating effect between organizational communication satisfaction and organizational commitment. Conclusions: The effective organization management system can enhance the job satisfaction, organizational commitment, and turnover intention reduction in the dental hygienists.

This study examined the relationship among supervision behaviors, self-efficacy, and job stress of childcare teachers for infants. This study also investigated whether the childcare teachers' supervision behaviors affected self-efficacy and job stress and whether their self-efficacy acted as a mediating effects on job stress and supervisory behaviors. The participants were 292 childcare teachers for infants in Seoul and Gyeonggi-do. The instruments utilized were the parent supervision attributes scale, Korean occupational stress scale, and teacher self-efficacy scale. The data analyzed by means of Pearson's correlation coefficients and hierarchical regression analysis. A hierarchical multiple regression analysis, Which Baron & Kenny first proposed, was conducted. The significance of the mediation effect was verified by the Sobel test. The results were as follows: First, the childcare teachers' supervision behaviors had a positive correlation with the teachers' self-efficacy, while the teachers' supervision behaviors and self-efficacy had a negative correlation with job stress. Second, job stress appeared to have a negative on supervision behaviors. Self-efficacy appeared to have a positive effect on supervision behaviors. Third, the mediating effect of self-efficacy was verified in the relationship between supervision behaviors and job stress. The more self-efficacy the childcare teachers had, the more supervision behaviors they performed. The greater their self-efficacy, the more the childcare teachers were able to control job stress. Therefore, by enhancing the self-efficacy of childcare teachers, their level of supervision behaviors should increase and their level of job stress should decrease.

Objective : This study aimed to examine impact of anxiety and demographic factors on relationship between severity of depressive symptom and quality of life and disability. Methods : One hundred ninety five patients who met DSM-IV-TR criteria for depressive disorder were enrolled. It includes "Hamilton Rating Scale for Depression (HRSD)", "State-Trait Anxiety Inventory-State (STAI-S)", "General Health Questionnaire/Quality of Life-12 (GHQ/QL-12)", and "Sheehan Disability Scale (SDS)". Correlation analysis was used to see the correlations of each variable. Hierarchical regression analysis was used to see mediating effect of anxiety in the relationship. Sobel test was used to verify mediating effect. Multiple regression analysis was used to see moderating effect of demographic factors in the relationship. Results : There was partial mediating effect of anxiety on the relationship between severity of depressive symptoms and decreased quality of life (z=-11.68, p<.001)/increased disability (z=10.42, p<.001). Only religion was found to be moderating effect on the relationship between depressive symptoms and decreased quality of life. Conclusion : Rapid relief of anxiety along with depressive symptom had important implications for the treatment of patients with depression.

Purpose: The purpose of this study was to assess the relationship between cognitive function impairment and quality of life (QoL) among patients with breast cancer. Specifically, the intention was to verify the mediating effects for promoting behaviors leading to better health and QoL. Methods: A purposive sample of 152 patients undergoing chemotherapy was recruited. A cross-sectional survey design was used. Data were collected using four instruments: Everyday Cognition Scale, Korean Mini-Mental State Examination, Functional Assessment of Cancer Therapy-Breast Cancer Version 4, and Health Promoting Lifestyle Profile. Results: The mean score for subjective cognitive decline was 65.84; the health promotion behavior was 95.89, and 83.34 for QoL. Health promotion behavior was directly affected by cognitive decline ($R^2=6.0%$) as was QoL ($R^2=43%$). Subjective cognitive decline (${\beta}=-.57$ p<.001) and health promotion behavior (${\beta}=.37$, p<.001) were seen as predicting factors in QoL and explained 56% ($R^2=56%$). Health promotion behavior had a partial mediating effect in the relationship between self-reported cognitive decline and QoL (Sobel test: Z=-3.37, p<.001). Conclusion: Based on the findings of this study, nursing intervention programs focusing on managing cognitive decline and promoting health promotion behavior are highly recommended to improve QoL in cancer patients.

Background: The study investigated the influence of culturally-based health beliefs on engagement in healthy lifestyle behaviour. Specifically, the study compared levels of engagement between Western and Chinese youth in Australia and assessed the extent to which culture-specific attributions about the causes of illness, and health beliefs, predict engagement in healthy lifestyle behaviour. Materials and Methods: Ninety-four Western and 95 Chinese (N=189; Mean Age=20.8 years, SD=3 years) young adults completed an online questionnaire. Predictor variables were cultural health beliefs measured by the Chinese Cultural Views on Health and Illness scale (CCVH, Liang et al., 2008), and illness attributions beliefs measured by the Cause of Illness Questionnaire (CIQ, Armstrong and Swartzman, 1999). Outcomes variables were levels of engagement in healthy lifestyle behaviour. Results: Results indicated that Chinese participants have a significantly lower exercising rate and healthy dietary habits compared to the Western sample. Moreover, Chinese participants were found to believe more strongly than Westerners that cancer was associated with factors measured by the Traditional-Chinese-Model (TCM). Finally, the observed relationship between cultural health beliefs and physical inactivity was mediated by attributions of illness, in particular to the supernatural subscale, with the Sobel Test showing a significant mediation (z=-2.63, p=0.004). Conclusions: Mainstream approaches to encourage healthy lifestyles are unlikely to be effective when educating Chinese youth. Instead, health promotion programs should attempt to address the illness attribution beliefs and educate Chinese youth about the role of diet and exercise in prevention of diseases such as cancer.
