This study tried to identify the influential users of college sports teams' Twitter accounts and categorize them into three groups including an official account, media account, and layperson account. A total of 14 Twitter accounts at NCAA Division 1 universities were selected through convenience sampling method. In men's sports, the greatest number of influential users was layperson account followed by media account and official account. In women's sports, the greatest number of influential users was layperson account followed by official account and media account. The results provided the insight of college sports online social network and will expand the growing literature on social media in sport and offer practical data for marketers to use social media more effectively.

The purpose of this study was to examine university students' consumption-orientation and attitude toward conspicuous consumption as well as to identify the factors that are most influential on consumption-orientation and conspicuous consumption behavior. The major findings of this study are summarized below. First, the average scores of consumption-orientation and conspicuous consumption were 2.71 and 3.15 respectively, on a 5 point scale. Second, the most influential factor on university students' consumption-orientation was friends' influence. Third, the most influential factor on conspicuous consumption was students' perceived social status. Fourth, conspicuous consumption tendency and consumption-orientation were significantly higher for those students with larger amount of allowances, female students, or the students who are working. Fifth, the university students' consumption-orientation and conspicuous consumption tendency were significantly higher for the students whose parents' child-rearing style is inconsistent or excessive investment. Finally, the consumption orientation has a significant positive relationship with conspicuous consumption.

This thesis investigates influential attributes in clothing purchase through the examination of questionnaire concerning consumer satisfaction at the point of purchase, and clarifies the relationship between consumer satisfaction at the point of purchase and that in wearing. The results are as follows; 1. At interest stage, color, beauty, becomingness and suitability to occasion are influential (in this order): at trial stage, becomingess, color, others' reaction and fit: at adaption stage, color, becomingness, beauty, fit. 2. According to canonical analysis, consumer satisfaction at the point of purchase and that in wearing are closely related. (RCI = .97) It suggests that satisfaction in wearing depends largely on satisfaction at the point of purchase. 3. General satisfaction in wearing is closely related with such factors as predictive expecta-tion, satisfaction at the point of purchase, predictive disconfirmation, normative disconfirrna-tion, and product performance. According to repression results, those factors can explain $79\%$ of satisfaction ill wearing (R = .79). Above all, product performance and normative disconfirmation are highly influential.

The purpose of this study was to examine the family resources, stress level, and coping strategies of reemployed wives, to direct the better psycho-physical environment, and to enhance the quality of their home environment for reemployed wives. The data were analyzed with the frequency, percentage, factor analysis, mean(S.D), reliability, and regression using SPSS windows program. The major findings were as follows : (1) There were significant relationships between demographic and socioeconomic characteristics of the family resources and stress level. Personal-psycho resources was important variable in the family resources. The household work and value of household work were most influential. (2) Influential variables on stress level were income and working hours, resources of family task sharing. (3) Influential variables on coping strategies were age, reemployed time, and family task sharing. Coping strategies was effected by the reasons of employment.

The purpose of this study is to identify the influential factors of clothing conspicous consumption, and the relationship between these consumer characteristics and clothing purchasing behaviors. The influential factors of clothing conspicous consumption are defined materialism, sensation seeking tendency and demographic characteristics. And clothing purchasing behavior can be defined such as fashion leadership, impulsive purchasing behaviors, bargain sale purchasing, and the price and total pieces of clothing. The data were collected from 320 female students of university using questionnaire, and were analysed with frequency, %, multiple regression, ANOVA and Duncan test. Reresults can be summerized as follows. First, clothing conspicous consumption was not influenced to sensation seeking tendency but materialism. Second, the sensation seeking tendency, materialism and clothing conspicous consumption was proven to be partially related to the clothing purchasing behaviors. Third, the demographic characteristics have influenced on the sensation seeking tendency, materialism, clothing conspicous consumption and clothing purchasing behaviors.

This paper suggests a new diagnostic measure for detecting influential observations in linear discriminant analysis (LDA). It is developed from a Bayesian point of view using a default Bayes factor obtained from the imaginary training sample methodology. The Bayes factor is taken as a criterion for testing homogeneity of covariance matrices in LDA model. It is noted that the effect of an observation over the criterion is fully explained by the diagnostic measure. We suggest a graphical method that can be taken as a tool for interpreting the diagnostic measure and detecting influential observations. Performance of the measure is examined through an illustrative example.

An influence measure known as Cook's distance has been used for judging the influence of each observation on the least squares estimate of the parameter vector. The distance does not reflect the distributional property of the change in the least squares estimator of the regression coefficients due to case deletions: the distribution has a covariance matrix of rank one and thus it has a support set determined by a line in the multidimensional Euclidean space. As a result, the use of Cook's distance may fail to correctly provide information about influential observations, and we study some reasons for the failure. Three illustrative examples will be provided, in which the use of Cook's distance fails to give the right information about influential observations or it provides the right information about the most influential observation. We will seek some reasons for the wrong or right provision of information.

The purpose of this study was to explore the effects of mother-child interaction and child's social behaviors on child's peer acceptance. Participants were 108 4- to 5-year-old preschoolers(58 boys, 50 girls) and their mothers. Data were analyzed by descriptive statistics, correlation analysis and stepwise multiple regression analysis. The major findings are summarized as follows: (1) mother-child interaction are generally correlated with child's peer acceptance. And child's prosocial behavior was positively correlated with child's peer acceptance, whereas child's aggressive behavior, asocial behavior and hyperactive-distractible behavior were negatively correlated with child's peer acceptance. (2) The most influential factor on child's peer acceptance was child's experience in session, the next influential factor was child's hyperactive-distractible behavior and the last influential factor was asocial behavior.
