The purpose of present study is to investigate mediating effects of emotional labor in the links between communication ability of small businessmen and customer orientation behavior. In detail, it is demonstrated both impacts of communication ability on customer orientation behavior and emotional labor (surface acting, deep acting), and of emotional labor (surface acting, deep acting) on customer orientation behavior. Furthermore, mediating effects of emotional labor (surface acting, deep acting) will be verified. The data for analysis was collected from 270 employees in small businessmen located in Jeju. The results are as follows. First, the main impacts of communication ability on customer orientation behavior and emotional labor (surface acting, deep acting) were statistically significant, in addition, emotional labor (surface acting) was positively associated with customer orientation behavior. Surface acting as a mediator was partially mediated the relation. The result will help to understand the importance for communication ability in small businessmen, and it suggests the crucial implecation in the communication study of service suppliers.

Given operators X and Y acting on a Hilbert space $\cal{H}$, an interpolating operator is a bounded operator A such that AX = Y. In this article, we showed the following : Let $\cal{L}$ be a subspace lattice acting on a Hilbert space $\cal{H}$ and let X and Y be operators in $\cal{B}(\cal{H})$. Let P be the projection onto $\bar{rangeX}$. If FE = EF for every $E\in\cal{L}$, then the following are equivalent: (1) $sup\{{{\parallel}E^{\perp}Yf\parallel\atop \parallel{E}^{\perp}Xf\parallel}\;:\;f{\in}\cal{H},\;E\in\cal{L}\}\$ < $\infty$, $\bar{range\;Y}\subset\bar{range\;X}$, and < Xf, Yg >=< Yf,Xg > for any f and g in $\cal{H}$. (2) There exists a self-adjoint operator A in Alg$\cal{L}$ such that AX = Y.

Purpose - Service employees who work at airline check-in counters in airport are typically employed to undergo emotional labor. Emotional labor of airport service employees is an important managerial issue that must be solved. This study attempts to examine the underlying mechanism of emotional labor on turnover intention. It focuses on the consequences of emotional labor of service employees. The purpose of this study is to examine and empirically test how the two-types of emotional labor(deep-acting & surface-acting) of service employees differently affect the level of their job satisfaction and job stress. It also investigates the relationship between job satisfaction, job stress, and turnover intention. For this purpose, first, this study identified the structural relationship between emotional labor, job satisfaction, job stress, and turnover intention. Second, it investigated the mediating effects of job satisfaction between deep-acting and turnover intention. Research design, data, and methodology - To empirically test these structural relationships among research variables, data were collected by a interview from service manager of domestic airline companies and survey from 179 service employees who are working at single domestic airline check-in counters in airports in Korea using a self-rating questionnaire with total 19 items dealing with emotional labor, job satisfaction, job stress, and turnover intention. To test the research hypotheses, collected data were analyzed by confirmatory factor analysis (CFA) and structure equation model (SEM). Results - This study obtains meaningful research results. The results from this study are as follows. First, deep-acting has a positive effect on job satisfaction, whereas, deep-acting has a negative effect on job satisfaction. Second, surface-acting has a positive effect on job stress, whereas, the effects of surface-acting on job satisfaction did not show statistically significant result. Also, job satisfaction has partial mediating roles to the relationship between deep-acting and turnover intention. Conclusions - Based on the results of this empirical study, emotional labor of service employees is one of the key factors influencing their job satisfaction and job stress. In particular, deep-acting is the important factor in emotional labor to increase job satisfaction and reduce job stress. Finally, theoretical, managerial implications, and research limitations are mentioned in discussion parts.

Purpose: This study was conducted to investigate the influence of emotional expressivity, emotional intelligence, affectivity, job autonomy, social support, and emotional labor on clinical nurses' individual well-being and to provide guidelines for interventions and strategies for its improvement. Methods: The sample consisted of 207 nurses recruited from a general hospital in Korea. The participants completed a structured self-report questionnaire comprising measures of emotional expressivity, emotional intelligence, positive affectivity, negative affectivity, job autonomy, supervisor support, coworker support, deep acting, surface acting, emotional exhaustion, and job satisfaction. Data were analyzed using SPSS statistics 22.0 and AMOS 22.0. Results: The final model was a good fit for the data based on the model fit indices. In the path analysis, surface acting, negative affectivity, supervisor support, and coworker support had statistically significant effects on emotional exhaustion, explaining 29.0% of the variance. Deep acting, emotional exhaustion, positive affectivity, and emotional intelligence had statistically significant effects on job satisfaction, explaining 43.0% of the variance. Conclusion: Effective strategies to improve clinical nurses' individual well-being should focus on surface acting, deep acting, affectivity, social support, and emotional intelligence. The results of this study can be utilized as base data to manage emotional labor and improve clinical nurses' individual well-being.

Purpose: This study was conducted to investigate nursing professionalism, emotional labor (surface acting, deep acting), empathic concern, and customer orientation, and identify factors contributing to customer orientation among clinical nurses. Methods: The participants in this study were 151 clinical nurses at the three general hospitals. Data were collected using self-administered questionnaires. Data were analyzed using descriptive statistics, independent t-test, one-way ANOVA, Pearson correlation coefficient, and multiple regression. Results: The significant predictors of customer orientation among clinical nurses were empathic concern (${\beta}=.43$, p<.001), nursing professionalism (${\beta}=.29$, p<.001), nursing career (${\beta}=.16$, p=.007), and deep acting (${\beta}=.14$, p=.021). Theses variables explained 47.6% of the variance of customer orientation. Empathic concern was the most influential variable. Conclusion: The results suggest that it is crucial to improve deep acting, empathic concern and nursing professionalism for increasing clinical nurses' customer orientation. Management-level leaders in the hospitals should develop strategies of promoting nursing professionalism, deep acting and empathic concern to improve customer orientation.

Cut and Cover Method is generally used in shallow tunnels and tunnel entrances with thin soil cover. In this type of cons0truction, backfilling is considered to be the most important process. In this process even though the backfill material is thoroughly compacted, compaction and self-weight due to vehicular vibration and pressure exerted by the soil cause the backfill material to undergo self-compression which leads to settlement. The settlement of the backfill material subjects the tunnel lining under excessive earth pressure which cause cracking and deformation. In the model test performed installation of geotextile on the sides and top of the tunnel was able to reduce the earth pressure acting on the tunnel lining.

The PID controllers which is widely used in the process industry are poorly damped when the dynamic process contains significant dead time or when there are random disturbances acting on the plant. GPC is known to be more superior than conventional self-tuning algorithm in overcoming above problem and prior choice of model order. In this paper, we propose the method which determine the parameter of PID controller from minimization of GPC criterion. The controller has emplicit scheme which is comprised of parameter estimation and PID control design. Simulation results show the performance of the proposed self-tuning PID controller.

Jeong Sun-Ah built up her performance career for twenty years with bold and energetic acting and solidified her status as a leading actress of Korean musical since her debut. To benefit from the value of her experience this study performed an in-depth interview with her, applying the Theory of "Projection" and "Back-projection", which are the psychological principles of acting, and derived "acting(entering the roles)" and "de-acting(leaving the roles)" techniques. As result, Her acting mechanism involved emptying her ego, embodying a persona by projecting the role created by intensive exploration of materials like previous performance, film of the same title, original novel, and script, and then getting the ego back by back-projecting through dynamic activities such as overseas travel and dance. She pre-studied the roles by physically visiting sites that are important to the characters. She was unique in that she pursued a difference by changing vocal trainers for each musical production and undertook more intense physical training than vocal practice to achieve powerful singing performance. In most of her works (75%), she suffered from aftereffects such as depression, narcissism, hysteria, and insomnia due to disorder caused by breaking away from the roles. However, she relied on self-help and alternatives are needed in the future such as reinforcement of expert counselling. Jeong Sun-Ah appeared on an average of 1.6 productions per year, practiced for an average of 1.7 months, and performed for an average of 3.9 months with an average of 100 days of break between productions. Her performance record from this research demonstrates her constant preparation and passion, as well as the know-how of reserving and distributing energy. So, it has a valuable implications for acting education and self-management of actors and actress.

The purpose of this study was to verify the differential influences of two emotional labor strategies on perceived CSS and burnout, and the mediating role of perceived CSS between emotional labor and burnout. The data was collected using self-reported questionnaires. A total of 568 hotel service employees who worked in various service jobs, participated in this study. The result indicated that surface acting had a positive influence on perceived CSS and burnout, and perceived CSS performed a mediating role between surface acting and burnout. In addition, deep acting had a negative effect on burnout but no effect on perceived CSS. As a result, deep acting reduced burnout without increasing perceived CSS, unlike surface acting. These results suggest that the two emotional labor strategies need to be treated differently. Finally, the implications and limitations of this study were discussed.
