This study examined how empowerment of restaurant cooks influences job satisfaction, organizational commitment, and customer orientation, targeting 260 restaurant cooks in the Busan area. SPSS 18.0 was employed to perform frequency, factor, reliability, and multiple (simple) regression analyses. Empowerment was analyzed using 3 factors (self-authority, meaning and competence) while job satisfaction, organizational commitment, and customer orientation were analyzed using 1 factor each. Results of a correlation analysis of the hypothesized model revealed positive correlations among the variables. Multiple (simple) regression analyses of the hypothesized model found that the sub empowerment factors will have a positive influence on job satisfaction with self-authority (${\beta}$=.372, p<.001), meaning (${\beta}$=.451, p<.001), competence (${\beta}$=.240, p<.001). It was also found that the sub empowerment factors will have a positive influence on organizational commitment with self-authority (${\beta}$=.433, p<.001), meaning (${\beta}$=.473, p<.001), competence (${\beta}$=.302, p<.001). Lastly, the hypotheses that job satisfaction will have a positive influence on organizational commitment (${\beta}$=.775, p<.001), that job satisfaction will have a positive influence on customer orientation (${\beta}$=.467, p<.001), and that organizational commitment will have a positive influence on customer orientation (${\beta}$=.567, p<.001) were adopted.

This study was a descriptive exploratory study to provide a foundation for improving the healthy working environment in Korean Red Cross Blood Center workers. A total of 215 surveys were collected from September 8 to October 31, 2020. Chi-squared test or Fisher's extract test, Independent t-tests, and Multiple Logistic Regression were performed with the SPSS 19.0 statistical program. We conducted multiple logistic regression analysis to evaluate the relationship between positive psychology capital and job stress with the perceived health status. The good perceived health status was 35.3%(N=76). When adjusted for related factors, the general characteristics and work characteristics were not related to perceived health status, and the positive psychological capital and job stress were significantly different between healthy and unhealthy groups (p<.001, p<.001). As positive psychology capital increased by one unit, the odds ratio of good health groups for subjective health increased significantly 1.1 times [95% Confidence interval (CI: 1.0-1.1)] and the odds ratio for good health groups for subjective health status decreased by 0.9 times [95% Confidence interval (CI: 0.8-0.9] as job stress increased by one unit.

This study was conducted to find out the psychosocial-demographic factors affecting the ambivalent sexism and attitudes toward homosexuality of school health teachers. The data were collected from December 1^st to 31^st, 2019 by administering a structured online questionnaire for 138 school health teachers in S city. The data were analyzed via SPSS/WIN (25.0) to run Kruskal-Wallis 𝑥² test, Mann-Whitney U test, Spearman's rank correlation, and Stepwise multiple regression. The results showed that the influential factors on the hostile sexism include authoritarian personality, age, extrinsic religious orientation, and education. Compared to this, the benevolent sexism had the influential factors of authoritarian personality, age, and education. The influential factors to the attitudes toward homosexuality found to include authoritarian personality, whether or not have a religion, and intrinsic/extrinsic religious orientation. School health teachers affect the educational experiences of students of their gender stereotyping and prejudice in the school environments. Therefore, it is needed to establish and provide training programs for school health teachers so that they can have reflections on their gender perspectives themselves, which may lead to true educational changes based on gender equality.

Bayesian inference and model selection method for software reliability growth models are studied. Software reliability growth models are used in testing stages of software development to model the error content and time intervals between software failures. In this paper, could avoid multiple integration using Gibbs sampling, which is a kind of Markov Chain Monte Carlo method to compute the posterior distribution. Bayesian inference for general order statistics models in software reliability with diffuse prior information and model selection method are studied. For model determination and selection, explored goodness of fit (the error sum of squares), trend tests. The methodology developed in this paper is exemplified with a software reliability random data set introduced by of Weibull distribution(shape 2 & scale 5) of Minitab (version 14) statistical package.

This study is an experimental analysis for local scour of the riverbed at pier. The basic equation with dimensionless elements(Pier Reynolds Number, Dimensionless Turbulence Intensity) is derived through dimensional analysis. After testing the goodness of fit of data, the coefficients are determined by multiple regression analysis. In the region where the value of the attack angle is near 20 degrees, there exists a transition region where the slope of equation with Pier Reynolds Number changes from positive to negative and that of equation with Dimensionless Turbulence Intensity changes from negative to positive adversely. As a result of testing the equation suggested on this study by using the data of the Institute of National Construction, it is found that the scour depth and width at pier can be predicted approximately.

Recently, one of the most outstanding technological characteristics of aerial survey is an application of Direct Georeferencing, which is based on the integration of main sensing sensors such as aerial camera or Lidar with positioning sensors GPS and IMU. In addition, a variety of digital aerial mapping cameras is developed and supplied with the verification of their technical superiority and applicability. In accordance with this requirement, the development of a multi-looking aerial photographing system is just making 3-D information acquisition and texture mapping possible for the dead areas arising from building side and high terrain variation where the use of traditional phptogrammetry is not valid. However, the development of a multi-looking camera integrating different sensors and multi-camera array causes some problems to conduct time synchronization among sensors and their geometric and radiometric calibration. The establishment of a test field for aerial sensor calibration is absolutely necessary to solve this problem. Therefore, this paper describes investigations for photogrammetric Test Field of foreign countries and suggest an establishment scheme for domestic test field.
