The purpose of this study is to identify the influences of psychological variables and fashion-related psychological variables on purchasing fashion items on the Internet. Boredom proneness and public self-consciousness were selected as psychological variables, and dressing style was selected as a fashion-related psychological variable. It was hypothesized that boredom proneness and public self-consciousness not only influence the purchasing frequency of fashion items on the Internet directly, but also indirectly through dressing style. Data were gathered by surveying university students in Seoul using convenience sampling. Two hundred and eighty-six questionnaires were used in the statistical analysis. SPSS was used for exploratory factor analysis, and AMOS was used for hypothesized relationship testing. The factor analysis of boredom proneness revealed five dimensions, "helplessness," "affective response," "lack of internal stimulation," "lack of external stimulation," and "perception of time." The factor analysis of public self-consciousness revealed two dimensions, "appearance-consciousness" and "style-consciousness," and the factor analysis of dressing style revealed one dimension. The overall fit of the hypothesized model suggests that the model fits the data well. The hypothesized relationship test proved that boredom proneness and public self-consciousness influence the purchasing frequency of fashion items on the Internet indirectly through dressing style. The results implicate effective strategies for Internet shopping malls and suggestions for future study.

The rule bases self organizing controller(SOC) has one of its main advantages in the fact that there is no need to have a mathematical description of the system to be controlled. In this controller, the rules are linguistics statements expressed mathematically through the concepts of fuzzy sets and correspond to the actions a human operator would take when controlling a given process. With this controller, we have performed to sight stabilization system, and we realize that it needs a scale factor tuning. The self tuning controller(STC) uses an instantaneous system fuzzy performance which can give an inspection to the scale factor. Therefore, the STC can compensate the scale factor when it is not adequately tuned. With this trial, we shows that STC can give a good transient characteristics in the nonlinearity which imposed basically in the conventional servo system.

This study was undertaken to investigate the factorial structure of clothing purchase motives, and to examine the relationship between clothing purchase motives, self-concept, and post-purchase clothing satisfaction of males. Questionnaire was comprised of three sections: 25 Likert type statements of clothing purchase motive measure; post-purchase clothing satisfaction measure; and three self-concepts measure(physical, personal, and social self-concept). For the measurement of self-concepts, a portion of‘Self-Concept Scale’by Wonshik Chung was used. Samples were 312 male white collar workers in Seoul, whose age were ranged from 20 to 39. the data were analyzed using factor analysis, Cronbach's alpha reliability coefficient, Pearson's correlation coefficient, and multiple regression analysis. The results of the study were the followings: 1. Six factors of clothing purchase motives derived by factor analysis. 21 items having a factor loading of ± .40 or higher were given consideration in the interpretation of each factor: F.1‘clothing dsign’; F.2‘fashion and impulsive buying’, F.3‘clothing utility’; F.4‘others influence’: F.5‘financial margin’; F.6‘clothing’2. Male consumers perceived the purchase motive of‘clothing design’to be the most important,‘clothing deficiency’the second important, and‘others influence’the least important. 3. Physical, personal, and social self-concept had positive relations to the purchase motive of‘clothing design’and negative relations to the‘clothing deficiency’. Physical self-concept had negative relation to the motive of‘others influence’. 4. Male consumers high in physical, personal, and social self-concept had more positive attitude in the evaluation of post-purchase clothing satisfaction. 5. Post-purchase clothing satisfaction was influenced most by the purchase motive of‘clothing design’, and next by physical self-concept, and age. Age of subjects had negative relation to post-purchase clothing satisfaction. The explanatory power of the 3 variables was 19.9%.

This article introduces the conceptual framework of self-efficacy and reviewes recent research articles which are related to development of self-efficacy in children. Self-efficacy means personal judgement about one's capability to organize his behavior in a specific situation. Perceived efficacy can have diverse effects on behavior, thought patterns and affective arousal. People acquire their efficacy information from their performance accomplishments, vicarious experiences, verbal persuasion and their physiological states. In this paper, I argue that two factors, psychological and environmental factor, contribute to the development of children's self-efficacy. Specifically reward, attributional feedback, social comparision and goal setting are classified to psychological factor and home environment, school environment and social environment belong to environmental factor. Since not many studies have been done in this area, in this paper I also suggest some directions for future research.

The purpose of this study was to develop a Parenting Self-Efficacy Scale for mothers of 5- to 7-year -old preschool children. After 43 items of the preliminary scale were analyzed for their fitness of structure based on the chi-square test and Cramer's V coefficients, and 27 were selected as the final set for the questionnaire. Further factor analysis on these 27 items confirmed the selection of 26 of the 27 items with a four-factor structure : communication, teaching, general parenting self-efficacy, and control. The internal reliability was evaluated to show a confidence level of .92 for the overall items and a range of .70 to .86 for each individual factor.

Even though self-confidence is a personal factor of a people, it works as behavioristic factor in consumer behavior. In this study, the influence of consumer self-confidence on clothing purchase behavior was investigated. A total of 284 data sets were analyzed after collecting questionnaires from college students in Seoul using convenient sampling method. For data analysis, chi-square test, analysis of variance, reliability test and factor analysis were performed by SPSSWIN program. The results were as followed. First, the clothing purchase places were affected by the consumers' level of self-confidence. The more confident consumers preferred internet shopping and Dongdaemun market to large-scale shops. The discount stores were selected by the less confident consumers. Second, information search was one of the main reasons to visit internet shopping mall by the more confident consumers. Third, the more confident consumers showed the higher level of clothing involvement than the less confident consumers. Finally, unplanned purchases, such as pure impulse buying and reminder buying were more likely to occur by the more confident consumers with less purchase conflicts.

Purpose: This study investigated the degree of fatigue of hemodialysis patients, and finds the relationship between fatigue and self-efficacy, family support, and sleep factor. Also, this study was purposed to provide fundamental data to help set up a nursing plan and intervention for recovery and mitigation of hemodialysis patient's fatigue. Method: The subjects in this study were patients treated as hemodialysis patients in Kwangjoo City. Data, subjects are 143 patients. Fatigue was measured using Lee's scale(1991), Self-efficacy using Kim's scale(1995), and Family support using Kim's scale(1993). For the analysis of collected data, Cronbach alpha, descriptive statistics, t-test, ANOVA, Pearson's correlation coefficient, Stepwise multiple regression were used for statistical analysis by SPSSwin(version 11.0) program. Result: Fatigue degree of hemodialysis patients averaged 4.22. Among 143 hemodialysis patients, 70.63% patients answered that they had felt fatigue as noted in this study. The weariest time was after hemodialysis for 21.0% patients. There was significant difference according to the diagnosis period. The patients who were diagnosed over one year had felt more fatigue than ones who were diagnosed within one year. Fatigue was significantly associated with self-efficacy, family support, and sleep factor. Self-efficacy could explain 14.6% of fatigue. Conclusion: The fatigue degree relates with all, self-efficacy, family support, and sleep factor. Especially, it is affected by self-efficacy among them. Thus, the program should be developed to mitigate fatigue as the self-efficacy of hemodialysis is enhanced.

The purpose of the study was to examine the internet purchase behavior of items and self-assessment according to self-concept of elementary school students. The data were collected from 716 elementary school students by a self-administered questionnaire. Frequencies and means, Cronbach's Alpha, factor analysis, t-test, Pearson's correlation analysis, cross-tabulation analysis, cluster Analysis were conducted by SPSSWIN 12.0. The results from this study were as follows; First, from self-concept measurements, 4 factors(affective, social, schooling, Family self-concept) were extracted through factor analysis. Second, the subjects were classified into 3 clusters as self-concept types(high self-concept, middle self-concept, low self-concept) through cluster analysis. Third, the significant variables affecting internet purchase behaviors of items included grade, allowance, rank in class, the number of hours on the internet. As the self-concept gets higher, the frequence of the impulsive purchase and imitation purchases gets lower. In the contrary, as the self-concept gets higher, the self-assessment on the impulse purchases and imitation purchases also gets higher. In combination, these results suggest that irrational purchase behaviors were protected by positive self-concept, therefore it is important that children have positive a self-concept.
