The main purpose of this paper is cost reduction in absurd pilot positive expense and human accident prevention which is caused by in the pilot selection process. We use classification models such as logistic regression, decision tree, and neural network based on aptitude test results of 505 ROK Air Force applicants in 2001~2004. First, we determine the reliability and propriety against the aptitude test system which has been improved. Based on this conference flight simulator test item was compared to the new aptitude test item in order to make additional yes or no decision from different models in terms of classification accuracy, ROC and Response Threshold side. Decision tree was selected as the most efficient for each sequential flight training result and the last flight training results predict excellent. Therefore, we propose that the standard of pilot selection be adopted by the decision tree and it presents in the aptitude test item which is new a conference flight simulator test.

The purpose of this study is to define the relationships among the emotional labor, job satisfaction, and turnover intention of beauty industry workers. The data for this study were collected through a survey, and a total of 197 questionnaires were used in the statistical analysis. The survey items were classified into 4 domains: demographic characteristics, emotional labor, job satisfaction, and turnover intention. This study extracted factors that compose each measurement domain to define the impact of emotional labor on job satisfaction or turnover intention. According to the research results, 3 factors - positive norm, sincere behavior, and emotional incongruity - were extracted for emotional labor. Individual aptitude satisfaction and work environment satisfaction were extracted as the factors for job satisfaction, whereas a single factor was extracted for turnover intention. By analyzing the effect of factors related to the emotional labor of beauty in dustry workers on factors related to job satisfaction, results showed that positive norm positively influenced individual aptitude satisfaction, sincere behavior positively influenced individual aptitude satisfaction and work environment satisfaction, and emotional incongruity negatively influenced individual aptitude satisfaction. Among factors related to emotional labor, positive norm and sincere behavior negatively affected turnover intention, whereas emotional incongruity positively influenced turnover intention. With regard to the effect of job satisfaction on the turnover intention of beauty industry workers, results showed that individual aptitude satisfaction and job environment satisfaction negatively (-) affected turnover intention. The results of this study show that people presenting a high level of individual aptitude satisfaction displayed positive job satisfaction, whereas people showing serious emotional incongruity for work presented high turnover intention. This implies that in order to increase the work efficiency of beauty businesses, it is essential to examine and manage the emotional labor of workers as a measure for increasing job satisfaction and lowering turnover.

The purpose of this study was to investigate the measurement equivalence and to suggest application ways in teaching aptitude and personality test results for pre-service mathematics teachers between a graduate school of education and a college of education. This study analyzed the scores of the teaching aptitude and personality test of 36 pre-service mathematics teachers enrolled in a graduate school of education and 111 pre-service mathematics teachers in a college of education by performing a multivariate generalizability analysis. The main results were as follows. First, graduate's pre-service mathematics teachers had a higher level of teaching aptitude and personality than that of college's pre-service mathematics teachers based on the total scores. In addition, graduate's pre-service mathematics teachers had higher levels of teaching aptitude and personality than those of college's pre-service mathematics teachers except for a creativity application domain based on the sub-domain scores. Second, cognitive domains were measured more precisely but affective domains were measured less precisely for graduate's pre-service mathematics teachers than for college's pre-service mathematics teachers. Third, regardless of school levels, Cronbach's ${\alpha}$ values, which might be overestimated by applying the classical test theory, were higher than dependability coefficients. Fourth, this study showed a somewhat negative result in ensuring the measurement equivalence for a problem solving exploration domain. However, regardless of school levels, this study indicated that the overall measurement was generally reliable on composite scores. Based on these results, it was confirmed that multivariate generalizability methodologies' approach can be useful for exploring the measurement equivalence issues. Finally, this study suggests how to utilize the results of the test, how to apply a multivariate generalizability analysis for detecting the measurement equivalence, and how to develop future research based on limitations.
