The purposes of this study were to segment knit wear consumers by their lifestyles and to examine knit wear purchase behavior among the lifestyle segments. The subjects of this study were female consumers who were residents in Seoul and metropolitan areas. The researchers distributed the questionnaires and the final sample of 357 was used for the data analysis. The statistical analysis methods used for the study were factor analysis, cluster analysis, ANOVA, Duncan test, and ${\chi}^2$-test. The results showed that the lifestyle factors had 6 dimensions: fashion, planned purchase, socially active, impulsive consumption, brand, and leisure/culture. These factors were categorized into four groups: brand oriented group, passive group, rational/social group, and fashion/impulsive consumption group. The results also showed that there were significant differences among the groups in regard to knit wear purchase criteria, knit wear image preferences, and other knit wear purchase behaviors. For example, brand oriented group considered design and brand name/fashion important as knit wear selection criteria, and the group preferred an elegance image and a modern image than did other groups.

With the increasing popularity of nonprofit thrift shopping, new marketing strategies are needed to respond to accelerated competition in the secondhand market. To help guide the development of marketing strategies for nonprofit thrift stores, this study aims to identify factors impacting consumers' buying behavior for secondhand fashion items sold in nonprofit thrift stores. Specifically, this study investigated 1) the effects of secondhand fashion selection criteria (i.e., design, brand name, lower price) and personal factors (i.e., gender, household income, beliefs about environment) on the secondhand fashion consumption experience in nonprofit thrift stores and 2) the moderating effects of point of purchase (POP) messages (i.e., "50% Off Sale," "New Arrivals," "Helping Others") on the relationships between purchase intention and impulsive buying in nonprofit thrift stores. An online survey was used to collect the data, and a total of 197 usable responses were received. The results showed that 1) gender, household income, beliefs about environment, and brand name affected the secondhand fashion consumption experience and 2) the POP message "Helping Others" negatively moderated the relationship between purchase intention and impulsive buying in nonprofit thrift stores. These results can help nonprofit thrift stores' managers to develop effective marketing strategies to increase their profits, which can be used to accomplish their mission of addressing social issues.

圓形斷面 部材를 갖는 해안 및 해양구조물의 설계에서 波力은 주로 正弦波의 입사를 가정한 모리슨식을 적용하여 산출하는 것이 상례이나. 구조물에 대하여 강한 卷波性 碎波가 작용할 경우에는 모리슨식에 의한 계산치보다 훨씬 큰 衝擊碎波力이 발생한다. 그러나, 충격쇄파력은 그 작용시간이 매우 짧기 때문에 구조물 설계로의 반영 여부 및 규모를 결정하기 위해서는 충격쇄파력 작용에 대한 구조물 전체의 動的擧動을 검토하여야 한다. 본 연구는 충격쇄파력의 작용에 의한 단일 연직파일의 동적변위를 해석하기 위한 수치해석기법을 수리하였으며, 파일의 제원을 달리하는 여러 예제해석을 통하여 파일의 정적변위와 동적 변위를 비교하였다.

This study classified consumers' behaviors of purchasing gifts, divided groups by the types of similar behaviors, and examined impacts of demographic variables, relevant variables in purchasing processes on those behaviors. Findings of this study can be summarized as follows. First, factors explaining consumers' behaviors of purchasing gifts were the tendency of demonstrative purchase, the level of placing values to the meaning of gifts, the level of altruism and rationality in the purchase of gifts, and the tendency of impulsive purchase. On the basis of these five factors, five distinct consumer groups showing similar behaviors of purchasing gifts based on the results of Cluster analysis were identified. Those groups were impulsiveㆍdemonstrative groups, impulsiveㆍnon-sincere groups, indifferent groups, non-impulsiveㆍdemonstrative groups, non-altruistic'ㆍrational groups, sincere groups, and altruisticㆍrational groups. Second, behaviors of purchasing gifts showed significant differences depending on gender, educational levels, occupational types, and women's employment status. Consumers with high education, professional occupation, high income tended to show the demonstrative purchase. Male consumers were not interested in the purchases of gifts and placed high values on the meanings of gifts. In contrast, female consumers showed rational behavior, but revealed the tendency of demonstrative in the purchase of gifts as well. Finally, behaviors of purchasing gifts were also different depending on the method of gathering consumer information, places of purchasing gifts, experiences of ordering paid wrapping gifts and the relevant costs, consumers' evaluations of the purchases of gifts, and degrees of satisfaction after the purchase of gifts. Impulsive'ㆍdemonstrative groups and non-impulsive'ㆍ demonstrative groups preferred departments as places of purchasing gifts and choose ordering paid wrapping gifts but showed dissatisfactions after purchases of gifts. Consumers who belongs to non-altruistic'ㆍrational groups, sincere groups, and altruistic'ㆍ rational groups tended to prefer local stores in their own villages as places of purchasing gifts and did not order paid wrapping gifts while showing high after the purchase of gifts.

Hydrodynamic behavior and response of vertical-cylindrical liquid-storage tank is considered. The equation of the liquid motion is shown by Laplace's differential equation with the fluid velocity potential. The solution of the Laplace's differential equation of the liquid motion is expressed with the modified Bessel functions. Only rigid tank is studied. The effective masses and heights for the tank contents are presented for engineering design model.

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.

Objective: This study aimed to find out whether concern for children mediates the impact of parenting competence on the anger expression of mothers with young children. Methods: Subjects consisted of 219 mothers with children aged 3 to 6 years old attending kindergartens and daycare centers. The motehrs were given 3 rating scales about parenting competence, concerns about their children, and anger expression. The Parental Anger Scales measuring anger expression consisted of sub-factors such as situational anger, impulsive behavior, and difficulty of anger control. Results: Using the data collected, correlation analysis and the regression analysis procedure by Baron & Kenny(1968) were conducted; the significance of the mediating effects was verified by the Sobel test. First, the study found that there were significant positive correlations between mother's parenting competence, concern about children, and anger expression. Second, mothers' concern about their children had partial mediating effects on the relationships between parenting competence and overall anger expression, situational anger and impulsive behavior, and a complete mediating effect on the relationship between parenting competence and difficulty with anger control. Conclusion/Implications: These results were discussed in terms of the approach and content of parent education to help parents with young children control their anger.
