This paper aims to investigate the relationship between consumption value of sports products, upward consumption propensity, and post-purchase happiness among adolescents. The subjects of the study were extracted from adolescents in Chungcheong-do by convenience sampling method, and 257 people were used in the final analysis. Statistical methods were frequency analysis, correlation analysis, and regression analysis. The research results are as follows. First, social value and exploratory value, which are sub-factors of consumption value, were shown to have a significant effect on upward consumption propensity, but functional value and self-value were found to be statistically insignificant. Second, social value, self-value, and functional value, which are sub-factors of consumption value, had a significant effect on post-purchase happiness, but exploratory value was found to be statistically insignificant. Third, the upward comparison propensity was found to have a significant effect on post-purchase happiness.

Contingent self-esteem can be maintained by meeting the standards of social or introjected values. This study investigated whether social media-related contingent self-esteem was associated with depression in Instagram users; in a sample of 319 Instagram users, we examined the effect of contingent self-esteem on depression and the mediating effect of upward social comparison on this theorized relationship. The study findings indicated that higher contingent self-esteem predicted higher levels of depression for a week in Instagram users, which could be explained by the upward social comparisons made on this application, and showed that Instagram users with higher contingent self-esteem tended to compare themselves with other users they considered superior, thereby increasing their depression. This study provided evidence for the mechanism underlying the association between using social media and psychological well-being and indicated the vulnerability of contingent self-esteem within the social media context. Other implications and future research directions were also discussed.

Incidental envy influences behavior in various domains. However, no research, to date, has investigated whether incidental envy influences interpersonal behavior toward others who are unrelated to the emergence of the emotion. That is, the literature is silent on how those who experience incidental envy engage in interpersonal contact and how this may affect consumers. In this paper, we address this question by investigating the influence of incidental envy on interpersonal contact with others of higher or lower status based on the social comparison theory. We demonstrate that incidental envy (versus a neutral emotion) motivates people to contact higher status others to facilitate upward assimilation (experiments 1 and 2). We also show that when competition (a situational factor that heightens the personal relevance of the interaction with the target) is involved, individuals who feel envy (versus a neutral emotion) are more likely to contact lower status others to engage in downward contrast (experiment 3). We conclude with a discussion of the practical implications of our findings.

This study purports to investigate the difference between upward and downward feedback and to find out the strategy to enhance the validity and reliability of the multi-source feedback system. Data were collected from 88 middle-level managers working at divisions of nursing, administration, and clinical technology at a university hospital located in north-eastern part of South Korea. Data about multi-source feedback of the year 2008 and 2009 were obtained from the department of personnel management under the permission of hospital top management. The collected data were analyzed using t-test, and correlation analysis. The major findings of the study were as follows: First, the scores of downward feedback were always higher than those of the upward feedback. Second, the scores of downward feedback were always higher than those of the upward feedback in both nursing and administrative staff, while no significant difference was found in technological staff. Third, the upward and downward feedback scores were significantly different in terms of the evaluation factors. Fourth, there were significant correlations between total scores of downward and upward feedback, and evaluation factor scores. In conclusion, the composition and weight of measurement items of multi-source feedback needs to be designed differently in terms of each job characteristics.

Social networking sites (SNS), such as Facebook, provide abundant social comparison opportunities. Given the widespread use of SNSs, the purpose of the present study was to examine the impact of exposure to social media-based social comparison on user's negative emotions and discontinuous use intention on SNS. We present evidence that under the use of SNS, social comparison activities diverge into three patterns, with explicit self-evaluation desire made against similar target (lateral comparison), self-defense desire made against less fortunate target (downward comparison), and self-enhancement desire made with more fortunate target (upward comparison). Such social comparison processes frequently arise, as people are increasingly using on SNSs, the downward contacts ameliorating self-esteem with positive emotions, but the upward contacts and standard contacts with lateral status enabling a person to compare his or her situation with others and simultaneously increase negative emotions due to its differences with others. In other words, as people increasingly relying on SNSs for a variety of everyday tasks, they risk overexposure to upward or standard social comparison information that may have a cumulative detrimental impact on future intention on SNS use. This study with survey with 209 SNS users found that these negative emotions lead to negative fatigue (attitude) and then discontinuous use intention (behavior) on SNS. Our findings are among the first to explicitly examine discontinuous use intention on SNS using social comparison theory and our results are consistent with those of past research showing that upward social comparisons can be detrimental.

Purpose: This study was conducted to evaluate the relationship between self-control behavior, social comparison attitude, self-efficacy and health promotion activities of college students who had health related majors (nursing, dental hygiene, health administration). Methods: The subjects consisted of 413 college students. Data were collected by self reported questionnaires that were designed to evaluate self-control behavior, social attitudes, self-efficacy and health promotion lifestyle (HPLP). Data were analyzed using the SPSS/PC win 14.0 program. Results: Upward & parallel comparison, self-efficacy and parents income were positively correlated with health promotion activities by college students. The most significant predictors of health promotion activities for college students were self-efficacy and self-control behavior. Conclusion: Health promotion activities for college students are influenced by self-efficacy, self-control behavior, and upward comparison. In conclusion, to increase the health promotion activities of college students, methods designed to increase self-efficacy should be prepared while considering the self-control behavior and comparative propensity towards others.

SNS (social networking service) plays an important role in delivering information regarding fashion brands and providing a space for communication between fashion retailers and SNS users, as well as between users. This study primarily focuses on exploring the relationships among the motivation of SNS users and social comparison, clothing purchasing behaviors and the difference in the relationships according to individual characteristics. An online survey was conducted on Chinese female consumers in their 20's and 30's who had experience in fashion SNS. A total of 297 women completed online survey. The results of the study revealed that: (1) consumers who have stronger motivation of information seeking and interpersonal communication through fashion SNS reached more active upward comparison and peer comparison accordingly; (2) upward comparison had a significant effect on conspicuous consumption and bandwagon, while peer comparison had no significant effect; and (3) the self-esteem of fashion SNS users significantly moderated the effect of social comparison on conspicuous consumption and conformity consumption. This study contributed to expanding the knowledge on the relationships among the motivations of SNS users and social comparison, and shed light on Chinese SNS users' characteristics and purchasing behaviors in the fashion SNS context. This study also provides vital implications to fashion brands and retailers.

Background: The serratus anterior (SA) muscle is one of the important muscles in the upward rotation of the scapula when the arm is raised. Insufficient muscle activity of the SA can cause deformation of the shoulder rhythm resulting in shoulder pathology. Objects: This study intends to compare SA and upper trapezius (UT) activity during the conventional wall-slide and push-up plus exercises for SA muscle strengthening and the scapular upward rotation (SUR) exercise. Methods: A total of 30 subjects participated in this study, and we measured the muscle activity of the SA and UT muscles during the wall-slide, push-up plus and SUR exercises. The one-way repeated ANOVA was used to compare SA and UT muscle activities during the 3 exercises. Results: During the SUR exercise, SA muscle activity was 79.88% maximum voluntary isometric contraction (MVIC), which was significantly higher than its activity during the other 2 exercises. The UT muscle activity was 47.53 %MVIC during the SUR exercise, indicating a significantly higher UT muscle activity than during the other 2 exercises. Conclusion: These findings suggest that the SUR exercise can maximize SA muscle activity to strengthen the SA while keeping UT muscle activity at an appropriate level.

The accuracy of the upward continuation is assessed through the gravity modeling using an ultra-high degree spherical harmonic expansion. The difficulties in the numerical calculation of Legendre function with ultra-high degree, underflow and/or overflow, is successfully resolved in 128 bit calculation scheme. Using the generated Legendre function, the gravity anomaly with spatial resolution of $1'{\times}1'$ on the geoid is calculated. The generated gravity anomaly is degraded and extracted with various noise levels and data intervals, then upward continuation is applied to each data sets. The comparison between the upward continued gravity disturbances and the directly calculated from the spherical harmonics showed that the accuracy on the direct method was significantly better than that of Poisson method. In addition, it is verified that the denser and less noised gravity data on the geoid generates better gravity disturbance vectors at an altitude. Especially, it is found that the gravity noise level less than 5mGal, and the data interval less than 2arcmin is necessary for next generation precision INS navigation which requires the accuracy of 5mGal or better at an altitude.

In the early 1990s, soil nailing was first introduced as method of reinforcement for the slope stability and ground excavation, and as its application was increased the improved soil nailing was also developed. Most recently used for grout soil nailing greatly improve the methods and techniques for self-improvement techniques are classified as soil nailing. As the representative for the grout pressure method to improve the join method pressure grouting and improved method for the self-drilled soil nailing, removable soil nailing, upward soil nailing combined with horizontal drainage system. This paper is to compare upward soil nailing combined with horizontal drainage system with downward direction of the soil nailing. In order to study the limit equilibrium slope stability analysis and comparison with factor of safage, excavation for the vertical displacement for comparison with continuous analysis. According to this study, safage factor is decreased considerably using limit equilibrium analysis and makes no odds for the horizontal displacement when soil nail was installed upward.
