The purpose of this study is to empirically analyze the impact of job stress on job turnover intention through job satisfaction for vocational counselors working in private and employment centers in Korea. This study applied the significance sampling method, and the number of samples used in the maximum analysis was 167 copies, and statistical analysis was conducted using the SPSS 20.0 program. In order to verify the relationship between each variable, four hypotheses were established, and empirical analysis and surveys were conducted. As a result of the analysis, first, among the sub-factors of job stress of vocational counselors, job demands, organizational systems, and workplace culture had a significant positive (+) effect on turnover intention. Second, among the sub-factors of job stress, job demand, lack of job autonomy, and organizational system were found to have a significant negative (-) effect on job satisfaction. Third, job satisfaction was found to have a significant negative (-) effect on turnover intention. Fourth, it was found that job satisfaction partially mediates complete mediation with job factors, which are sub-factors of job stress, with the organizational system. Therefore, it can be seen that job stress of vocational counselors is a factor affecting turnover intention and job satisfaction. Based on these analysis results, the implications of the study, suggestions to reduce the intention to change jobs due to stress of vocational counselors, and limitations of the study were presented.

In this study, a nonlinear dynamic analysis of a frame and single member, which reflect the characteristics of a plant facility, is performed using the commercial MIDAS GEN program and the results are analyzed. The general structural members and material properties of the plant are considered. The Newmark average-acceleration numerical-analysis method is applied to a plastic hinge to study material nonlinearity. The blast load of a vapor-cloud explosion, a representative plant explosion, is calculated, and nonlinear dynamic analysis is conducted on a frame and single member. The observed dynamic behavior is organized according to the ratio of natural period to load duration, maximum displacement, ductility, and rotation angle. The conditions and range under which the frame functions as a single member are analyzed and derived. NSFF with a beam-column stiffness ratio of 0.5 and ductility of 2.0 or more can be simplified and analyzed as FFC, whereas NSPF with a beam-column stiffness ratio of 0.5 and ductility of 1.5 or more can be simplified and analyzed as FPC. The results of this study can serve as guidelines for the blast-resistant design of plant facilities.

In this paper, we propose a 3-D geometric localization method for near-field broadband source in shallow water environments. According to the waveguide invariant theory, slope of the interference pattern which is seen in a sensor spectrogram directly proportional to a range of the source. The relative ratio of the range between source and sensors was estimated by matching of two interference patterns in spectrogram. Then this ratio is applied to the Apollonius's circle which shows the locus of a source whose range ratio from two sensors is constant. Two Apollonius's circles from three sensors make the intersection point that means the horizontal range and the azimuth angle of the source. And this intersection point is constant with source depth. Therefore the source depth can be estimated using 3-D hyperboloid equation whose range difference from two sensors is constant. To evaluate a performance of the proposed localization algorithm, simulation is performed using acoustic propagation program and analysis of localization error is demonstrated. From simulation results, error estimate for range and depth is described within 50 m and 15 m respectively.
