  • A new way to reduce the eigenvalue computation effort in structural dynamics is presented in this paper. The degrees of freedom of a structure may be classified into groups that are termed as sub-degrees of freedom. The eigenvalue analysis is performed with each of sub-degrees of freedom so that the computing time is much shortened. Since the dynamic coupling between sub-degrees of freedom is selected to be small and it may be considered as a perturbation, the perturbation algorithm is used to obtain an accuratae result. The accuracy of perturbation depends on the coupling between sub-degrees of freedom. The weaker the coupling is, the more accurate the result is. The procedure can be used to simplify a problem of three dimensions to that of two dimensions or from two dimensions to one dimension. The application to a truss and a space frame is shown in the paper.

  • The term used to describe consumer's valuation of a brand is brand equity. One concept that can be managed and may impact valuation of a prestige brand is "luxuriousness." As the concept of "luxuriousness" appears to be a key factor contributing to the equity of a prestige brand, the purpose of this study was to examine how luxuriousness is related to the brand equity utilizing a model developed by Yoo, Donthu, and Lee (2000). Yoo et al. (2000) identified three dimensions [brand association with awareness (BA), perceived quality (PQ), brand loyalty (BL)] accounted for the equity (OBE) of a brand. We speculated that the five dimensions of luxuriousness (i.e., quality, extended self, hedonism, accessibility, and tradition) would selectively influence the two dimensions of brand equity (BA, PQ) and that loyalty would mediate the relationship between the two dimensions of brand equity (BA, PQ) and overall brand equity. A total of 502 participants aged from 18 to 74 were surveyed in USA. Using AMOS 18, the path analysis was conducted with the maximum-likelihood estimation procedure. The model exhibited a good fit with the data and all hypotheses were supported except one. Quality, accessibility, and hedonism dimensions of luxuriousness affected perceived quality of the equity of a brand. Hedonism and extended self dimensions affected brand association with awareness. However, tradition dimension did not significantly influence brand association with awareness. Overall, this research expands understanding of brand equity as it documents the contributions of luxuriousness, a component that can be controlled by brand managers.

  • This study, the second in two part series, focuses on effect of product involvement and consumer knowledge on consumers' perceptions of six dimensions of clothing price: price -quality schema, prestige sensitivity: sale proneness, price mavenism, value consciousness, and price consciousness. Additionally, correlation between product involvement and consumer knowledge was examined. Multi-item measures of six dimensions of price, product involvement, and consumer knowledge were included in the questionnaires. The subjects were 264 college students living in Seoul, Korea. The data were collected by self-administered questionnaires and analyzed by factor analysis, regression analysis, and correlation analysis using SPSS PC. In addition, two focus group interviews were conducted to obtain qualitative data for the result interpretation. Results of this study showed that the degree of consumers' product involvement significantly affects consumers' perceptions of each price dimension except price consciousness dimension. Consumers' knowledge about clothing has a significant effect on consumers' perceptions of all price dimensions. Dimensions of product involvement and consumer knowledge were partially correlated. Marketing implications based on these results were suggested.

  • This study aims to investigate variables affecting the business performance of Muslim women entrepreneurs in Sri Lanka. A multidimensional analysis was proposed with five potentially defined antecedents of business performance which included psychological characteristics, human capital, social capital, industrial factor, and cultural factor. Data was collected from 286 respondents through the use of a self-administered questionnaire. The results of structural equation modeling indicate that the model meets the goodness-of-fit indices and that generally, all five factors have significant positive relationships with business performance. Amongst the dimensions of psychological characteristics, only risk-taking had a notable effect on business performance. Amongst the dimensions of human capital, two of the three dimensions (business experience and business skills) were significantly associated with business performance; in the case of social capital, one of the two dimensions (non-familial affiliations) was significantly associated with business performance; and in the case of industrial factor, resource accessibility was significantly associated with business performance. A strong positive correlation with business performance has also been demonstrated by the cultural factor which was a new concept to the paradigm as a whole. This study has broadened the understanding of existing literature on Muslim women entrepreneurship and contributed practical implications to government, policymakers and other related agencies, chambers of commerce, the general public, as well as the Muslim women entrepreneurs themselves.

  • This study was performed to measure the various dimensions of the head and face for Korean adults. Three hundred and eighteen males and two hundred and sixty females, age ranged 18 to 60, participated for this study. Thirty-six dimensions were selected to measure. Subjects were divided into three age groups - 18 to 29, 30 to 39, and 40 to 60 - for each sex. The data were analyzed ta see the differences between the age groups and sex using SAS program. Also, the results of this study were compared to the data of Japanese and US. army. The results showed that the 'ear length', 'bigonial breadth' and 'bitragion submandibular arc' increased as the age increased(p<0.01). However, not much of differences were shown between the age groups in most of other dimensions. Males were significantly bigger than females in every dimensions. The comparison between Korea and Japanese showed significant differences in many dimensions. Due to this reason, it is considered that more caution has to be exercised in using Japanese data for the Korean. The Americans showed to be significantly bigger than Korean in most dimensions. It showed that Koreans have more roundish face and wider nose ridge than Americans. The results of this study can be used to design the products that related to the head and face.

  • Design equations for anthropometric product design are developed by considering the geometrical relationships of design dimensions and anthropometric dimensions. The present study applied the design structure matrix (DSM) method to the development of design equations for a computer workstation, and compared design values from the design equations with corresponding design values of ergonomic recommendations and existing products. The relationships between design dimensions (e.g., legroom and worktable) were analyzed by a DSM, and then the application order of design equations (e.g., seatpan, backrest, armrest, legroom, and worktable in descending order) was determined. Next, design equations were developed by analyzing the geometric relationships between computer workstation design dimensions and anthropometric dimensions. Finally, design values for a computer workstation were determined by considering a standard posture defined and representative human models (5th, 50th, 95th %ile). The design values calculated using the design equations were similar with those of ergonomic recommendations found in literature and two commercial products measured in the study; however, some design values (e.g., seatpan height) were different due to discrepancy in standard posture. The DSM method would be utilized to systematically analyze the relationships between design dimensions for anthropometric product design.

  • The purpose of this study was to identify and compare the dimensions and patterns of the perception of traditional food for Koreans living in Yanbian, Mongolia and Uzbekistan. Items representing the perception of traditional food were combined into a dimension and a pattern based on underlying perception of the Koreans living in the area. Any difference in the perception of the Koreans living in these areas likely reflects their different dimensions and patterns. Thus, it is important to determine if Koreans living in Yanbian, Mongolia and Uzbekistan should be treated as a homogeneous group when defining their perceptional structure of traditional food. Factor and cluster analysis of the data generated in this study revealed two different dimensions and patterns for each group of Koreans living in Yanbian, Mongolia and Uzbekistan. However, the structure of the dimensions and patterns of the perception of traditional food differed, indicating that Koreans within and between the countries are not a homogeneous group. Similarities and differences in perceptional dimensions and patterns among Yanbian, Mongolian and Uzbekistan-Koreans are also discussed. Moreover, future implications for food and nutrition specialists, especially for those who have an interest in Korean traditional food in Asia and those who have an interest in globalization of Korean traditional food are provided.

  • The importance of VMD operation strategies in fashion business is growing, and this study analyzed the difference in consumers' VMD cognition of the two VMD operation systems: VMD specialist employment system and VMD outsourcing system. Two SPA brands were selected as the representative cases of the two VMD operation systems. A statistical analysis was performed using data collected from a total of 206 university and graduate students from an experimental study. Paired t-test and independent t-test were used for the analysis. The results are as follow: First, consumers' VMD cognition of the two VMD operating systems were different, and the VMD specialist employment system was valued higher than the VMD outsourcing system in all cognition dimensions. Second, the VMD specialist employment system was valued generally higher than the VMD outsourcing system regardless of gender, clothing involvement, and VMD interest of consumers. Third, the VMD specialist employment system was valued higher than the VMD outsourcing system in the following aesthetic aspects: harmony, attractiveness, and fashionable dimensions by the male, low involvement, and the VMD interested consumers. Fourth, the VMD outsourcing system was valued higher than the VMD specialist employment system in the appropriateness and the functionality dimensions by females and the high-involvement consumers, It also scored higher in the fashionable and attractive dimensions by the VMD interested consumers.
