This study examined the effect of valence for best reply on the conformity of general reply in online environment. A total of 194 participants participated in this study, each participant assigned randomly in three experimental groups(positive, negative, and control). Participants were asked to read online news article, best reply and general 6 replies, and then, to write their own opinions in the reply section. In addition, the level of self-expression and issue commitment were measured. The contents of reply participants written was categorized three valence(positive, negative, and neutral) by the four experimenters' judgment. The mean of inter-rater reliability was 84.9%. The results indicated that the level of self-expression and issue commitment were comparable across experimental conditions. However, the result of cross-table analysis showed that there is a significant difference in the valence of general reply across experimental conditions. Specifically, there were significant difference in the valence of general reply between positive and negative experimental group and positive and control group, but there is no significant difference between negative and control group.

This paper was an examination of gender-specific behaviors in children and the types of bullying behavior among 1,181 fifth and sixth grade elementary schools student identified were then classified. Differences were identified in individual variables, family variables, and school variables. The data thus collected were subjected to descriptive and comparative statistical analysis using the SPSS software program. Our results showed that multiple discriminant analysis yielded a function of individual, family and school variables that proved effective in classifying bully, reinforcer, assistant, victim, outsider and defender types in boys. In girls, multiple discriminant analysis yielded a function of individual variables that was effective in classifying bully, reinforcer, assistant, victim, outsider and defender types.

Attitudes and behavior within the store congestion of the store is a store in any manner affect the formation process of investigating synchronism in the control of the consumer appears to analyze the influence of enemy has its purpose. Store and spatial congestion factor of social behavioral factors also revisit the help of word-of-mouth is. Consumer groups with high and low groups of synchronism suggested. Social attitudes towards the store congestion significantly positive effect that I've shown, it was not significant spatial congestion. During a revisit of action is a statistically significant relationship that I've shown, is a significant effect of word-of-mouth relationship was not significant. Investigating the moderating effects of consumer synchronism result of high consumer groups a significant impact on the social congestion showed, at low spatial influence congestion.

The purpose of this thesis was to analyze shopping orientations of adolescence and to understand the reasons of their dissatisfactions in purchasing garments at so-called internet malls. This study was to provide basic information helpful in clothing study by finding out dissatisfactory factors of adolescence purchasing clothes through internet malls. This survey was done among 273 students of 3 junior-high schools and 3 high schools within the boundary of Seoul and its suburb area, among which 265 of them were qualified as legitimate survey. The results were as follows. First, the youth shopping trends were divided into the 5 categories according to the basic trends. And the 5 categories were 'Convenience seeking', 'Peer-assimilating', 'Personality/trend worshipping', 'Passive and inactive', and 'Thrifty' The survey represented that girls showed higher garment assimilating rate and made better economic choices than boys did. The survey also showed that the highschool students used internet shopping mall in order to seek better prices. furthermore, the primary targets of the juvenile internet shopping were shoes and garments, which includes both upper and lower clothing. Second, The dissatisfaction factors of internet shopping were the 'Mismatch of the goods in the screen and those of the real life', 'Exchange/Refund', 'Qualify', 'Desigin and color', 'Shipping', and 'Size' in order of biggest to the smallest. The dissatisfaction rate was higher among the groups of 'Thrifty', 'Personality/Trend worshipping', 'Convenience seeking', girls and highschool goers.

This paper proposes a self-organizing fuzzy modeling which can create a new hyperplane-shaped cluster by applying multiple regression to input/output data with relatively large fuzzy entropy, add the new cluster to fuzzy rule base and adjust parameters of the fuzzy model in repetition. Tn the coarse tuning, weighted recursive least squared algorithm and fuzzy C-regression model clustering are used and in the fine tuning, gradient descent algorithm is used to adjust parameters of the fuzzy model precisely And learning rates are optimized by utilizing meiosis-genetic algorithm. To check the effectiveness and feasibility of the suggested algorithm, four representative examples for system identification are examined and the performance of the identified fuzzy model is demonstrated in comparison with that of the conventional fuzzy models.

This study examined how consumers in their 20s and 30s perceive luxury goods, masstige brands, and counterfeits, which have high social value, and whether the propensity for conspicuous consumption and conformity can explain them. Consumers were classified based on the similarity of attitudes toward these brands and purchase intentions. The groups were compared on the sub-dimensions of conspicuous consumption and conformity. Clustering analysis identified four groups, and the MANOVA result confirmed the differences among the groups. Personality (F=4.282, p=.006) and brand orientation (F=23.178, p=.000) were positively related to luxury and masstige brands. Fashion orientation (F=8.376, p=.000) was high for both groups, which likes luxury and masstige brands very much, and which likes counterfeits. High-price orientation did not make any significant difference among the groups. Conformity (F=3.537, p=.015) was high for all the groups, except for the group that liked luxury and masstige brands and did not like counterfeits. This study comprehensively examined the attitudes and purchase intentions of luxury and masstige brands and their counterfeits and can be the groundwork for further research on brand categorization.

The purpose of this study was to determine psychosocial variables of exercise behaviors for old adults. A major research problem identified through theory of planned behavior and it's empirical data: Do cognitive-social variables(health risk perception, self-efficacy, group conformity, exercise attitude) significantly mediate exercise behaviors(intention, action, maintenance)? A total of 453 older adults above 65 years(171 males and 282 females) who were enrolled in various classes were randomly selected at adults centers in Seoul. Participants completed a battery of questionnaires including the psycho-social variables(health risk perception, self-efficacy, group conformity, exercise attitude) and exercise behaviors(intention, action, maintenance). The results of statistical procedures(e.g., hierarchical multiple regression) indicated self-efficacy and exercise attitude significantly predicted exercise intentions of older adults. Exercise intention was a significant predictor of action, and action was a significant predictor of exercise maintenance. In discussion, various psycho-social mechanisms were provided to interpret the results of this study, and future directions were suggested.

The purpose of this study was to identify the influence of reference group on the adolescents' behavior of fashion brand conformity. As for the method of the research, questionnaires were given to 672 students of middle school and high school. The results of this study were as follows: First, the differences between disposition of general conformity and behavior of fashion brand conformity were found to be meaningful in the dimensions of reference groups and their influences. Second, the classification between stage of brand consideration and stage of brand choice was found to be significant in the two-stage model of brand choice. Finally, the subjective individualism and the behavior of brand conformity were significantly correlated and the mass media stars & the identificational influence were the most powerful factors to explain the behavior of fashion brand conformity for the adolescents.
