The purpose of this study was to examine the comprehensive relationships among personal characteristics, shopping orientations, and attitude which impact department store patronage behavior of apparel shopping. The data were collected via questionnaires from convenient samples of 290 female college students. Statistical analysis of factor analysis and multiple regression analysis were performed in analysing the data. The shopping orientations seemed to be the most important variable in predicting both attitude toward and patronage behavior of department store for apparel shopping. In predicting shopping orientations, material value and income found to be the important variables.

This paper describes variable speed drive and power control of a doubly fed induction machine(DFIM) for wind energy generation without rotational transducers. A stator flux orientation scheme and rotor speed estimator are employed to achieve decouple control of active and reactive power. To verify the theoretical analysis, a 5-hp DFIM prototype system and PWM power converter are built. Results of computer simulation are presented to support the discussion.

쾌속조형 공정의 파트 성형 방향 결정 문제는 파트 표면의 품질, 제작시간, 파트 가격 등에 영향을 미치므로 대단히 중요하다. 실제적으로 이들 중요 변수들끼리는 모델제작과정에서 trade-off가 존재한다. 실제 파트 성형 방향 결정은 작업자의 경험이나 시행착오에 의해서 파트의 방향이 결정하고 있어 조금 복잡한 파트에 대해서는 최적의 성형을 결정하기 매우 힘들다. 일반적으로 쾌속조형 공정은 작업동안 공정변수가 변하지 않는 일정한 층두께를 가지고 작업을 수행한다.(중략)

Equations of chordwise and flapwise bending motions for the vibration analysis of rotating pre-twisted blades having tapered cross section and setting angle are derived by using hybrid deformation variable modeling. The two motions are couples to each other due to the pre-twisted angle of the beam cross section. The derived equations are transformed into dimensionless forms in which dimensionless parameters are identified. The effects of the dimensionless parameters on the modal characteristics of rotating pre-twisted blades having tapered cross section and orientation angle are investigated. The eigenvalue loci veering phenomena are also investigated and discussed in this work.

A continuum-based configuration design sensitivity analysis method is developed for kinematically driven mechanical systems. The configuration design variable for mechanical systems is defined. The 3-1-3 Euler angle is employed as the orientation design variable. Kinematic admissibility conditions of configuration design change. Direct differentiation method is used to derive the governing equations of the design sensitivity. Numerical examples are presented to demonstrate the validity and effectiveness of the proposed method.

The purpose of this study is to investigate the effects of 4-value orientations on the financial management and the financial satisfaction of high school girls in Yanbian, China and those in South Korea. The subjects were 466 high school girls in Yanbian, China and 498 high school girls in South Korea. Cronbach'a, 1-test, and multiple regression were used as statistical analysis. The results were summarized as follows : 1) Resulting from the t-test, there were significant differences between 3-value orientations, 3-financial management behaviors, and financial satisfaction of the Yanbian girls and those of the Korean girls. 2) Resulting from multiple regression analysis, the financial management behaviors of school girls had the positive linear relationships with the variables such as 3-value orientations and country variable, The financial satisfaction of school girls had the positive linear relationships with the variables such as 4-value orientations and country variable.

This study is a theoretical approach by literature about life style and housing life style. The purpose of this research is making an analysis model of housing life style which can be used as a conceptual framework in empirical study. the theme of‘Life style’was studied mainly in the area of consumerism and housing. Model was made to explore the sub-domain of new analysis model by the microsociological approach. As results, 1) Independent variable of housing life style research model must be selected to be possible of comparison in effect of objective and subjective variable and in effect of predictive function and well-being function of housing life style. 2) Sub-domain of housing life style must be consisted of value orientation of family life, consumption in house, consumer durables, furniture., and propensity to using space. 3) Conceptual model of housing life style must be tested in empirical study to know what is the housing adjustment behavior of individual family, to improve quality of housing life and to suggest housing policy for family as a consumer.

For the first time, the parametric instability characteristics of tow-steered variable stiffness composite laminated (VSCL) cylindrical panels is investigated using B-spline finite strip method (FSM). The panel is considered containing geometrical defects including cutout and delamination. The material properties are assumed to vary along the panel axial length of any lamina according to a linear fiber-orientation variation. A uniformly distributed inplane longitudinal loading varies harmoni-cally with time is considered. The instability load frequency regions corresponding to the assumed in-plane parametric load-ing is derived using the Bolotin's first order approximation through an energy approach. In order to demonstrate the capabili-ties of the developed formulation in predicting stability behavior of the thin-walled VSCL structures, some representative results are obtained and compared with those in the literature wherever available. It is shown that the B-spline FSM is a proper tool for extracting the stability boundaries of perforated delaminated VSCL panels.

The purpose of this study is to identify family stress and to specify family stress and socio-psychological resources which are associated variable. For the evidence of this topic, research was conducted on 258 married persons dwelling in seoul. The questionnare was composed of Family Stressor Inventory referred by McCubbin's FILE(1981) and Sarason's LES(1979) and Socio-Psychological Family Resources Inventory referred by McCubbin's FIRM(1983). This study offers to us that family income significantly has positive correlation with socio-psychological family resources and family income is potential variable which intensifies family tension or burden. This study touched only some variables, moreover, this is only a starting-point of family stress study in Korea. So further studies would consider latent variables, process, limited situation, family interaction pattern, family orientation, etc., and subjective variables would be reflected.

We investigated how entrepreneurship, information technology acceptance, and media utilization influence on office worker commitment and how effects are modulated by learning orientation. The purpose of this study is to identify variables that influence on office worker commitment. To do so, entrepreneurship, information technology acceptance, and media utilization that are the core competencies of individuals and organizations in the era of smart information are proposed as predictor variables, office worker commitment as a outcome variable and learning orientation as a modulator. For this study, a questionnaire survey was conducted on office workers, and finally 340 valid questionnaires are used for analysis. Hierarchical regression analysis is used with demographic characteristics as control variables and learning orientation as a modulating variables. A result showed that the higher need for achievement and proactiveness of entrepreneurship is, the higher job commitment is and that the perceived usefulness of information technology acceptance and communication utilization ability of media utilization competitiveness have a positive effect on job commitment. A research showed that learning orientation is modulating the relationship between entrepreneurship and job commitment, and between media utilization capability and job commitment, respectively. We concluded that we should actively seek synergies of learning orientation along with accumulation of online communication utilization capacity and perceived usefulness of information technology, and of proactiveness need for achievement and in entrepreneurship in order to improve the work committment in the smart information society where the digital environment is advanced.
