The decision to actively reveal oneself as a consumer on social media depends on whether the focus is more on positive rewards than negative threats associated with self-presentation, that is, who the other party is in that relationship. The audience of self-presentation could also be divided into expressive and instrumental ties: work partners can be classified as an audience of instrumental ties, whereas school friends can be regarded as an audience of expressive ties. This study accordingly predicted that people would focus more on prevention of negative threats than positive reward, exhibiting defensive self-presentation in relationships with strong instrumental ties because the fallout from negative threats due to failed self-presentation have a more detrimental effect than a positive reward from successful self-presentation. The empirical findings thereby indicated that as the proportion of coworkers increased among Facebook friends, the mediation effect through defensive self-presentation increased, whereas such effect through acquisitive self-presentation decreased.

This study examines the feelings of positivity and negativity generated through upward social comparison and explores the impact of the results of the emotions on SNS users' posting behavior. In particular, this study aims to systematically identify the influence of upward social comparison on SNS followers and uploaders' SNS usage behavior and the structural principle of social network circulation in which followers become uploaders again. According to the analysis, interaction-oriented followers made negative upward social comparison and positive upward social comparison, while negative upward social comparison reduced the publication of independence tendency. However, positive upward social comparison has been shown to increase both independent and interactive postings. The results of this study are meaningful in that SNS has expanded the results of prior studies, in which social comparison theories were biased toward negative upward comparisons, to positive upward comparisons. In addition, this study suggested a practical strategy for SNS platform operators on how SNS users would not deviate from other platforms.

The purposes of the study is builded upon previous researches to set up research model and investigate the relationship among store image, customers' emotional responses and behavior intention. For achieving study purposes, research model and hypotheses were set up after reviewing previous researches. The data were collected from a sample of 296 customers of department store, then used to conducted an empirical analysis. The results showed the significant relationship were partially found among store image, emotional responses and behavior intention. Objective store image influence positive emotions, indirectly influence behavior intention through positive emotions, but objective store image don't influence negative emotions. Subjective store image influence shoppers' positive emotions and negative emotions, and indirectly influence shoppers' behavior intention through positive emotions and negative emotions.

As the fourth industrial revolution has progressed globally, computing education is progressing centered on robots. However, pre-service teachers' attitudes toward robots were negative in previous studies. In order to solve this problem, this study analyzed the difference in the attitude of the pre-service teachers to the robot according to the factors. The subjects of this study were 309 pre-service teachers attending K university. In order to measure the attitude of the pre-service teacher to the robot, the negative attitude measure for the robot was used. And, in order to measure the attitude of the pre-service teachers to the robots, negative attitude measurement scale was used. As a result, pre-service teachers showed different attitudes toward robots according to gender, experience of robot manipulation, and experiences of robot-related lectures. Especially, when the gender was male than female, and the experience of robot manipulation and the experiences of robot-related lectures, the attitude of pre-service teachers to robot was positive.

In this study, the researcher analyzed relationship between stuents' science anxiety and achivement, and investigated the tendency of the science anxiety by students' variables. For the survey of this study. 5,304 stuents were sampled from the population of Korean secondary school. The researcher adopted R&D procedure for the development of SAMS(science anxiety measurement scale) and the SAT(science achivement test). The instrument SAMS consisted of 38-item scale. Cronbach a for SAMS was 0.92, concurrent validity was 0.66. SAT consist of 2O-item, the reliable coefficent of KR-20 was 0.70. The data were analyzed by using Pearson-Product coefficient and Regression analysis for the correlation between dependent and independent variable. The tendency of science anxiety were analyzed Multi-way analysis of variance, and all hypotheses were evaluated as the significant level of 0.001. Results of this study were summarized as follows : 1) The relationship between the science anxiety and the achivement showed negative correlation(r=-O.24) in all grades. 2) The relationship between the male and the female showed negative correlation (male;r=-Q.23. female=-O.22), but 11ths' humanities course and female of the science course didn't showed correlation. 3) The size of city where the school located showed negative correlation to the students anxiety(big city;-O27. medium;-O.24, small city;-O.22). 4) Tendency of students' science anxiety according to the variable of grades and sex variables was found to significant difference. The effects of interaction were found to significant difference between two variables of grade and sex. sex and local, local and grade. The effects among three variables were formed to significant difference grade, sex and local.

The study aimed to compare the validity between the abdominal ultrasonographic(US) grading system of fatty liver and histologic grading system of fatty liver in living liver donor candidates. As the fatty liver is defined as pathologic total fat >10%, US validity was sensitivity 64.6%, specificity 68%, positive predictive value 76.8%, negative predictive value 54%. As the strict data handling on US grading normal, mild fatty liver are negative, moderate fatty liver is positive, US validity was sensitivity 26.8%, specificity 100%, positive predictive value 100%, negative predictive value 45.5%. ROC curve analysis according to different cut off value of liver-to-kidney brightness ratio was Area under ROC curve=0.859(95% CI=0.795~0.922, state variable= total fat 10%). There were statistically significant difference( p<0.001). Ultrasonography for the fatty diagnosis showed a high validity to predict the result of histology grade of fatty liver.
