  • A low-Reynolds-number second moment turbulence closure was developed with the aid of DNS data. Model coefficients of nonlinear return to isotropy term were derived by use of Cayley-Hamilton theorem and two component turbulence limit condition as the functions of invariances of anisotropy and turbulent Reynolds number. Launder and Tselepidakis' cubic mean pressure strain model was modified to fit the predicted pressure-strain components to the DNS data. Two component turbulence limit condition was the precondition to be satisfied in developing the second moment turbulence closure for the realizable Reynolds stress prediction. But the satisfactions of Reynolds stress level and pressure-strain level of each component were compromised because the satisfaction of both levels was impossible.

  • The purpose of this study is to critically review the previous research on the measurement of service quality, and to present future research directions on hotel service quality measurement as follows: 1. As Carman(1990) shows in his study, items of quality measurement should be developed to be fit for the measurement of hotel service quality. 2. To evaluate the service quality of a hotel, measuring three divisions(Room, F&B and Others) separately, then combining them would be the best model. 3. Researches to identify the various dimensions of hotel service quality are needed. 4. In measuring hotel service quality, guests should be classified according to various criteria. 5. To measure the hotel service quality, SERVPERF model might be more a, pp.opriate due to the small number of items to be answered. 6. In hotel industry, researches to identify causal pths between customer satisfaction and service quality are needed. 7. We need to develop alternative scales for the measurement of hotel service quality.

  • The purpose of this study was to develop a measurement model for evaluation of residential environment in low-income families. Residential environment means the housing unit itself and neighborhoods and community characteristics. Based on the previous research on housing environment, six factors (comfortable environment in indoor and outdoor, facilities environment in complex and community, sociopsychological environment, management and economic environment) were selected to evaluate residential environment and to provided a foundation for exploring the multidimensional factors of this research. As s confirmatory study, an Analysis of Linear Structural Relationships(LISREL) was utilized to develop the model. Despite of some measurement errors, the goodness of fit of an overall model was acceptable. Facilities environment in complex and sociopsychological environment were the most important factors in residential environmental evaluation of the low income families. the findings showed that housing policies and programs to improve the quality of homes in low-income families seemed to be beneficial to improve residential satisfaction of the residents.

  • The purpose of the study was to investigate jean consumption among middle-aged Korean women and the characteristics of consumers as potential jean consumers. The data were collected from the survey of 238 Korean women aged 45 to 64 years old. The respondents prefer outlet store to other retail outlets and wear jeans mainly for travel, grocery shopping, and outing. The main reason for not wearing jeans is body change, which leads to poor fit in abdomen and waist area. The sample was clustered into two groups based on interest in jeans: high-interest and low-interest group. From the examination of group differences, the high-interest group rated conformity/brand reputation, scarcity, and attractiveness of appearance significantly higher compared to the low-interest group among the five clothing benefits pursued. No difference was found in obesity and body satisfaction. Group differences were found in recent purchase, price, number of jeans owned, and frequency of wearing jeans. The results suggest the characteristics of the potential jean market among middle-aged women in Korea. Implications are discussed.

  • The present study investigatesthe reliability and validity of the innovation leadership scale. Originally the seven factors with 25 items were developed through literature review. With a sample of 177 employees in a large company, the results of factor analyses showed that the five-factor model with 14 items had a better fit to the data than the seven-factor model. These five factors were innovativeness pursue, problem solving, vision presentation, risk-taking, and showing initiative. All of these factors were significantly related to various criteria such as identification with the group, attachment to the group, organizational commitment, and supervisor satisfaction, confirming criterion-related validity of the scale. Results of multiple regression analyses showedthat risk taking and showing initiative were more important predictors in explaining criteria. Finally, implications and limitations were discussed. The findings suggest that the key factors of innovation leadership were initiative and risk-taking.

  • The purpose of this research was to examine the construct known as job fit perceived by service employees in the foodservice industry. The model was tested using SPSS 12.0 and AMOS 4.0 based on the sample of 667 persons that showed a 95% usable response rate. The results of the empirical analysis showed as follows. First, in restaurants, the employees' job suitability factor brings about an indirect effect by organizational commitment and turnover intention. Second, employees' job satisfaction factor causes an indirect effect by organizational commitment. Third, employees' organizational commitment factor has relationships with turnover intention. That is, the higher organizational commitment, the lower turnover intention. By the same route analysis, job suitability has an effect on organizational commitment. Also, the research proved organizational immersion has an effect on turnover intention. In this respect, the research contributes to job performance of foodservice employees, emphasizing the necessity of educational programs for them.

  • This study empirically investigated the changes of performance evaluation systems under the environment of supply-chain e-commerce. The objectives of e-commerce include obtaining financial profit, internal innovation through processes integration, learning with information flow, and customer satisfaction through quick response. These objectives are generally consistent with the four evaluation measures of balanced scorecard(BSC). This study, first, demonstrated that perceived environmental uncertainty(PEU) has a significant effect on the adoptions of e-commerce and BSC, and severe competition positively influences the use of e-commerce. With cluster analysis and subgroup analysis, we also showed that under the high adoption levels of e-commerce, the high utilization of BSC can improve the supply-chain performance of a firm. In addition, it was found that the use of e-commerce indirectly and significantly affects supply-chain performance through inter-organizational information flow, and the supply-chain performance of a firm leads to the improvement of organizational performance.

  • A lot of researchers have been interested in the factors influencing the use of mobile phone services. Most of the previous studies, however, verified only the research models developed by the authors. They did not consider which model agrees better with the real situation. This study presents six alternative models based on various previous studies, and compares the data fitness of the models. A Web survey of mobile phone users collected 2,217 cases. Statistical analyses, using SEM (Structural Equation Modeling), show that the fitness of the simplest alternative model is better than that of any other model. The simplest model has no causal relationship among exogenous factors, and proposes that all of exogenous factors have direct impacts on the customer satisfaction. In addition, the analyses say that corporate and brand image and additional service are more important than the other exogenous factors such as communication quality.

  • The purpose of this study was to investigate the cognitive mechanism of e-Learning contents development projects on the basis of the Shared Mental Model theory perspective. To pursue the purpose, a theoretical model and several hypotheses were developed based on relevant literature. Thirty five (35) e-Learning contents development teams composed of 202 instructional designers from for-profit professional e-Learning companies in Korea were participated in this study. For the analyses of the fit of the Model and parameter estimations, Structural Equation Modeling (SEM) method was employed. As hypothesized, e-Learning contents development team members' interaction leads to higher SMMs which in turn facilitate member satisfaction within the team. Meanwhile, the frequency of interaction among team members decreases as projects progress.
