  • This study investigates the emotional labor of fast fashion sales personnel using the qualitative research method. The research was performed through an in-depth interview with 10 sales personnel (managers, coordinators, head cashiers, and sales associates) who experienced fast fashion brands from July to October in 2011. The results of this study provide that fast fashion brands do have specific feeling rules and display behavior. Even though the sales personnel spend an extremely short time (about 1 minute) to serve customers, most of them experience exhaustion, fatigue, burnout and self-alienation because of emotional dissonance. Sales personnel do deep-acting and surface acting simultaneously and interviewees who have longer and more sales experience express less emotional dissonance. To reduce the negative results of emotional labor, the company plays an important role through the organizational culture; in addition, deep-acting could be recommended for a beginner until they are comfortable with sales. The results of this study provide the elements of emotional labor in a fast fashion and practical suggestions for store operation and sales personnel training.

  • A three-dimensional WIG (Wing In Ground effect) moving above free surface is numerically studied by means of finite difference techniques. The air flow field around the WIG is analyzed by MAC (Marker & Cell) method, and interactions between WIG and the free surface are appeared as the variation of pressure distribution acting on the free surface. To analyze the wavemaking phenomena by those pressure distributions, the NS (Navier-Stokes) solver is employed in which nonlinearities of the free surface conditions can be included. Through the numerical simulation, Cp values and lift/drag ratio are carefully reviewed by changing the height/chord ratio. The section shape of model is NACA0012 with the span/chord ratio of 3.0. Through computational results, it is confirmed that the effect of free surface is small enough to treat it as a rigid wavy wall.

  • A mirror cam mechanism a kind of conjugate cam mechanism consists of two cams, two rollers, and two links. Since profiles of two mirror cam are identical, a simultaneous machining of two cams is achievable. Some machining errors on cam profiles do not result in the internal acting force, which often causes problems in high speed cam mechanism between two links. Also, since angular accelerations of two links are same, the internal acting force by the difference of the angular accelerations does not occur in the mechanism. Thus the mirror cam mechanism is very useful in high speed machinery. This paper studies a design method as well as a machining method, and develops an exclusive CAD/CAM software for mirror cam profiles. The developed CAD/CAM software is applied to a typical mirror cam mechanism and a mock-up equipment is built in order to test the machinism mirror cm. Experimental investigations show that the contact between cam surface and roller surface according to cam rotation agrees well with the simulation on the developed CAD/CAM software.

  • Purpose: The purpose of this study was to identify the effects of emotional labor and self-efficacy on psychosocial stress of nurses. Methods: A cross-sectional correlation study design was used. The participants were 186 nurses from two general hospitals in Jeju Island, South Korea. A self-report questionnaire was used to collect data including data on emotional labor, self-efficacy, and psychosocial stress. Data were analyzed using descriptive statistics, Pearson correlation coefficient, t-test, ANOVA, and hierarchical multiple regression. Results: Approximately 98% of the participants were categorized as having potential and high risk stress levels. Hierarchical multiple regression showed that employment status, surface-acting, and self-efficacy explained 37.0% of psychosocial stress and self-efficacy was the main factor influencing psychosocial stress. Conclusion: Nursing administrators should understand that nurses suffer from high risk stress and emotional labor. To reduce the psychosocial stress of nurses, there is needed to improve stressful work conditions such as irregular employment, decrease surface-acting, and improve self-efficacy.

  • The incident bore impact loads acting on a tall structure is simulated using the refined Moving Particle Simulation (MPS) method. The particle method is more feasible and effective than conventional grid-based methods for the violent free-surface problems. In the present study, the simulation results for the temporal change of the hydrodynamic force on the structure and longitudinal velocity component around the structure are compared with the experiments (Radd and Bidoae, 2005). And the mitigation effects by installation of various obstacles in front of the main structure are investigated and discussed form the simulation results.

  • We have developed a composite grid method for the solution of the radiation problem We divide the domain into two different grids; one is a moving grid system and the other is a fixed grid system. This numerical method is applied to calculation of the radiation forces generated by the submerged plate oscillating near a free surface. The experimental data are compared with the numerical ones obtained by the present method and a linear potential theory. As a result, we can confirm the accuracy of the present method. Finally, Lie have evaluated the effect of nonlinear and viscous damping on the hydrodynamic forces acting on the submerged plate.

  • In hydraulic machinery, the hydraulic fluid acts primarily as working fluid and secondarily as a lubricant. Hence, the viscous friction force acting on the sliding components should be reduced to improve the mechanical efficiency. It is now well known that the surface texturing is a useful method for friction reduction. In this study, using a commercial computational fluid dynamics (CFD) code, FLUENT, the lubrication characteristics of a surface textured slider bearing under high boundary pressure difference is studied. The streamlines, velocity profiles, pressure distributions, load capacity, friction force and leakage flowrate are highly affected by the film thickness ratio and the textured region. Partial texturing at the inlet region of the inclined slider bearing can reduce both friction force and leakage flowrate than in the untextured case. The present results can be used to improve the lubrication characteristics of hydraulic machinery.

  • The purpose of this study is to suggest the implications of social welfare workers' understanding of emotional labor and prevention of psychological exhaustion. In order to achieve this goal, I analyzed the effects of the levels of surface acting and deep acting, which are components of emotional labor in social welfare workers in social welfare center, on emotional exhaustion, depersonalization, and lack of sense of personal accomplishment which are components of psychological exhaustion. And I empirically analyzed how emotional labor affects psychological exhaustion, when superior support and fellow support as components of social support play a role as moderating variables. Empirical results show that emotional labor affects psychological exhaustion and social support plays a moderating role. Based on these results, theoretical and policy implications and future research directions are presented.
