In this study, the effect of caisson heel on the active earth pressure is investigated. Using limit analysis method, inclinations of slip surface developed above the heel with different lengths are analyzed. The shorter the heel length, the larger those of inside slip surface, however those of outside slip surface are not changed. According to the relative heel length, relationships of internal friction angle of backfill material - wall friction angle between caisson structure and backfill - friction angle acting on virtual section at the end of heel are presented. Earth pressures acting against caisson structure with relatively short heel are smaller than Rankine earth pressure but always greater than Coulomb earth pressure which does not consider the heel length.

Objectives: This study aimed to provide basic data to establish a foundation for efficient operation of the organization by identifying the factors that affect the job embeddedness of dental hygienists. Methods: A survey was conducted from March to July 2018, targeting dental hygienists working in dental clinics and hospitals. Results: The study of the factors affecting job embeddedness of dental hygienists revealed that along with career, marital status, surface acting of emotional labor, and even emotional hiding and false expression, which are sub-areas of the surface acting, have statistically significant influences on job embeddedness. In other words, in a married dental hygienist with relatively high work experience, the surface acting of emotional labor is found to be high in job embeddedness, and the explanatory power of the model is approximately 53.2%. Conclusions: In order to improve the job embeddedness of clinical dental hygienists, it seems necessary to prepare an effective program to strengthen the surface behavior of emotional labor.

The purpose of this study was to examine the effect of subordinates' emotional labor on job burnout and job engagement, and verify whether job crafting moderates the relationships between emotional labor and job related attitudes. A total of 301 employees working at various companies in Korea participated in an on-line survey and the data were examined by statistical analysis. The results showed that surface acting positively affected job burnout. It was found that deep acting positively affected job engagement, while negatively affecting job burnout. The results also demonstrated that job crafting moderated the relationship between surface acting and job engagement. It is suggested that employees' proactive behaviors designed to relieve the stress of work can mitigate the negative effect of emotional behavior. On the basis of the results, the implications and future research directions were discussed.

The purpose of this study is to investigate the influence of social workers' emotional labor on non-task behaviors. This study characterizes emotional labor as deep acting and surface acting, non-task behavior as organizational citizenship behavior(OCB) and counterproductive work behavior(CWB). And this study also examines the mediating effect of social workers' emotional dissonance in the relationship between surface acting and non-task behavior, and the moderating effect of senior worker's emotional leadership in the relationship between emotional dissonance and non-task behaviors. The results from this study are as follows. Firstly, social workers' deep acting improves their OCB. Secondly, social workers' surface acting has strong effects on their emotional dissonance, and this emotional dissonance hinders their OCB. In addition, the mediating effect of emotional dissonance is also recognized at this point. Thirdly, senior worker's emotional leadership moderates the relationship between social worker's emotional dissonance and OCB in the sense that emotional leadership is expected to reduce the negative effects of emotional dissonance on OCB. However, the influence of emotional labor on CWB has no statistical significance in this study. Based on these results, detailed theoretical and practical implications are discussed.

The propeller induced forces acting on a hull are surface forces and bearing forces. The bearing forces are the forces acting directly on the propeller which are transferred to the hull through the propeller bearings. The surface forces are those which act by fluid pressure directly on the various hull surfaces. Because the surface force is main source to oscillate stern constructions and deckhouse, the estimation of surface force is very important to predict response of forced vibration of that. The estimation methods were statistical analysis method, theoretical analysis method and method through model test.

Formulation of the far-field method for the prediction of time-mean hydrodynamic force and moment acting on a 3-D surface-piercing body in waves is reviewed. It is found that the inequality between the weight of the floating body and its buoyancy force permits the replacement of the fluid particles inside the control surface by the fluid particles outside the control surface. Under such circumstances, momentum exchanges across the control surface make the time-mean value of the time rate of the momentum of the fluid inside the control surface non-vanishing. It is a second-order quantity which is hard to calculate by the far-field method. The drift forces and moments on half-immersed ellipsoids are calculated by both the far-field method and the near-field method. The discrepancy between two numerical results is presented and discussed.

This study examined the mediating effect of emotional labor in the relations between teachers' emotional intelligence and teacher-child interaction of novice early childhood teachers. The sample consisted of 248 novice early childhood teachers in Gyeonggi Province. The structural equation modeling was conducted using AMOS to test the fit of a hypothesized structural model. The mediating effect of emotional labor was verified by the bootstrapping approach. The results were as follows: First, teacher-child interaction was positively associated with teachers' emotional intelligence and deep acting in emotional labor was negatively associated with surface acting in emotional labor. Next, surface acting in emotional labor had a mediating effect on the relations between emotional intelligence and teacher-child interaction. Finally, deep acting of emotional labor had a partial mediating effect on the relationship between emotional intelligence and teacher-child interaction. Based on these findings, ways to enhance teachers' emotional intelligence in relation to the novice teachers' emotional characteristics, and to improve recognition on emotional labor were discussed.

Background: The emotional labor performed by organization members affects psychological well-being at the individual level, which consequently affects results at the organizational level. Moreover, despite evidence that the customer orientation and service level of nurses greatly affect hospital management, studies that comprehensively analyze emotional labor, work burnout, and work engagement related to customer orientation and service level are lacking. This study investigated relationships and paths by designing a model of the effect of emotional labor performed by nurses on the level of service delivery and customer orientation. Methods: This survey-based study was based on a path analysis designed to verify a hypothesized model involving emotional labor performed by nurses, level of service delivery, customer orientation, work engagement, and burnout. Questionnaires were distributed to 378 nurses in general hospitals with more than 500 beds located in Seoul, Republic of Korea, between March 25 and April 8, 2013. Results: The results showed that deep acting and work engagement had direct and indirect effects on increasing the level of service delivery and customer orientation of nurses. However, surface acting had an indirect effect on reducing the level of service delivery and customer orientation. Conclusion: It would be more effective to develop interventions to enhance deep acting and work engagement than to attempt to reduce surface acting and work burnout in clinical nursing settings.

This study aimed to examine the cause and consequence of emotional labor strategies based on the emotional labor framework. To investigate the boundary condition of the current research model, the study proposed that job autonomy would moderate the effects of emotional labor on employees' well-being. To achieve the purpose of the study, it was first tested whether neuroticism and extroversion of employees predicted the focal outcomes (i.e., burnout and work engagement) via distinct emotional labor strategies. Second, the moderation effects of job autonomy were tested for each emotional labor strategy in predicting the focal outcomes. Third, the conditional indirect effects of job autonomy on the mediation process were examined. The results revealed that surface acting partially mediated the relationship between neuroticism and burnout, whereas deep acting fully mediated the relationship between extraversion and work engagement. Regarding the moderating effects of job autonomy, it significantly moderated the relationship between surface acting and burnout and between deep acting and work engagement. In addition, from the moderated mediation effects, the conditional indirect effects of job autonomy were significant. Finally, theoretical and practical implications are discussed and limitations and future research directions were suggested.

The purpose of this study was to find out the linkage between emotional display rules and emotional labor strategy and the affects of the display rule factors on the emotional labor strategy. The participants of this study were 268 childcare teachers in Seoul, and the collected data were analyzed using correlation analysis and multiple regression analysis. The results were as follows: First, display rule perception was positively related to deep acting and surface acting. And the deep acting was positively related to display rule education, commitment, fairness of display rule, and explicit display rule. Second, display rule perception has a positive effect on deep acting and surface acting. And the commitment to display rule has a positive effect on deep acting. This study provided practical implications to help childcare teachers' emotional labor, and suggested directions for the education program for the emotional competence of childcare teachers.
