The purpose of this study is to investigate how certain factors influence job satisfaction and turnover intention of the dietitians working at the correctional institutions. A total 47 sheets of questionnaires (complete enumeration) were distributed respectively to the dietitians during the period from March 20th to May 18th of 2008. A total of 38 questionnaires (response rate 81%) were analyzed by using SPSS (ver. 19.0). The dietitians were more satisfied with coworkers ($3.63{\pm}0.10$) and supervision ($3.19{\pm}0.13$) than with pay ($2.97{\pm}0.09$) and promotion ($2.55{\pm}0.08$). Among the job burnout dimensions, cynicism ($2.58{\pm}0.09$) was rated higher than exhaustion ($2.47{\pm}0.10$), while professional efficacy level ($3.40{\pm}0.08$) was relatively high. The work dimension of job satisfaction was negatively correlated with exhaustion and cynicism dimensions of job burnout (p < 0.001), and turnover intention (p < 0.01), but positively correlated with professional efficacy dimension (p < 0.001). The co-worker dimension was negatively correlated with exhaustion and cynicism (p < 0.05) and turnover intention (p < 0.01), while the supervision, the pay, and the promotion dimension were not correlated with the job burnout and turnover intention. The turnover intention was positively correlated with exhaustion and cynicism dimensions of job burnout (p < 0.001). A stepwise regression analysis revealed that i) professional efficacy was a factor to significantly increase the work dimension of job satisfaction, ii) exhaustion and cynicism to significantly decrease the work and the co-worker dimension of job satisfaction, respectively, and iii) exhaustion to significantly increase turnover intention. The managerial efforts of the institutions could be focused on the job burnout factors to effectively increase the work dimension and the co-worker dimension of the job satisfaction.

The effects of Korean Red Ginseng (KRG) in rats submitted to exhaustion exercise have been studied, by measuring different enzymatic and hematological parameters in plasma and muscle. KRG powder was daily administered to 15 male Wistar rats for a period of two weeks. Another group of 15 rats with the same characteristics were administered physiological saline. Both groups were divided as follows: 5 control. 5 exercised till exhaustion and 5 recovered for 48 h after exhaustion. The following results were obtained for the groups treated with KRG in rapport to those treated with saline: - Higher endurance to running, - Increase of the osmotic resistence of red blood cells and higher presence of reticulocytes. - Lower triglyceride levels in plasma. - Increase non statistically significant of urea levels in plasma, - Lower non statistically significant hypoglycemia after exhaustion exercise. - Decrease of liver glycogen after exercise and faster recovery of the resting - level. - Protective effect on tissular damage produced by exhaustion exercise - Lower LDH activity in all studied muscles. only statistically significant in the WG.

This study was conducted to analyze the turnover intentions of railway traffic controllers among employees of a domestic railway corporation. Variables influencing job turnover intention included exploited variables (empowerment, job stress, job satisfaction, organizational commitment, exhaustion) that have been actively studied in other fields. The results showed that the empowerment of railway traffic controllers did not directly affect job stress and turnover intention, but had a direct effect on job satisfaction, organizational commitment, and exhaustion. Job stress did not directly affect job satisfaction, organizational commitment, and exhaustion, and job satisfaction did not directly affect organizational commitment, burnout, and turnover intentions. Burnout has a direct effect on turnover intention, indicating that exhaustion of railroad traffic controllers has an effect on turnover intentions. In conclusion, empowerment has a direct effect on burnout and exhaustion has a direct effect on turnover intention. This study suggests that management of empowerment and exhaustion is important for the prevention of turnover of railway traffic controllers.

Kubernetes is a representative open-source software for container orchestration, playing a crucial role in monitoring and managing resources allocated to containers. As container environments become prevalent, security threats targeting containers continue to rise, with resource exhaustion attacks being a prominent example. These attacks involve distributing malicious crypto-mining software in containerized form to hijack computing resources, thereby affecting the operation of the host and other containers that share resources. Previous research has focused on detecting resource depletion attacks, so technology to respond when attacks occur is lacking. This paper proposes a reinforcement learning-based dynamic resource management framework for detecting and responding to resource exhaustion attacks and malicious containers running in Kubernetes environments. To achieve this, we define the environment's state, actions, and rewards from the perspective of responding to resource exhaustion attacks using reinforcement learning. It is expected that the proposed methodology will contribute to establishing a robust defense against resource exhaustion attacks in container environments

This study aimed to verify the mediating effect of job burnout on the relationship between work overload and turnover intention among IT workers. For this study, a sample of 499 IT workers completed the online questionnaires: job demand scale, job burnout(emotional exhaustion, cynicism, professional efficacy) scale, turnover intention scale. The collected data were statistically analyzed using SPSS 25.0, and the Sobel test was conducted to verify the mediating effect. The results showed that work overload had a significant positive correlation with emotional exhaustion, cynicism, and turnover intention. Work overload had significant positive effects on emotional exhaustion and turnover intention. The full mediating effect of emotional exhaustion on the relationship between work overload and turnover intention was verified. Based on the findings, we discussed the necessity of addressing emotional exhaustion to prevent issues related to work overload and turnover intention among IT workers. Finally, we proposed human resource management strategies to address job burnout in IT workers and suggested directions for future research.

Purpose - The present study examines the effect of service employees' experienced customer incivility through their emotional exhaustion. We identified service employees' emotion regulation ability as a boundary condition (i.e., moderating variable) that decreased the positive relationship between service employees' experienced customer incivility and their emotional exhaustion. Furthermore, we also investigated the negative relationship between service employees' experienced customer incivility and their service performance via emotional exhaustion. Research design, data, and methodology - Drawing on AET (affective event theory) and COR (conservation of resources) theory, we developed three research hypotheses (i.e., mediation, moderation, and moderated mediation). Online panel survey data from 552 frontline employees at several service organizations (e.g., department stores, retail stores, hotels, restaurants, airlines, banking, insurance company, and etc) in South Korea were examined. To assess two types of validity (i.e., convergent and discriminant validity) and reliability of measurement model, we employed the CFA (confirmatory factor analysis) using M-plus 8.2 software. Internal consistency also was tested by Cronbach' α. In addition, we employed the SPSS PROCESS MACRO 2.16, which was recommended by Hayes (2013, 2015), to estimate mediation, moderation, and moderated mediation effects. Results - As predicted, the negative relationship between service employees' experienced customer incivility and their service performance was mediated by emotional exhaustion. Furthermore, service employees' emotion regulation ability also played a significant moderating role of the relationship between service employees' experienced customer incivility and emotional exhaustion, such that this relationship was less pronounced when service employees had a high level of their emotion regulation ability than when thir emotion regulation ability was low. Service employees' emotion regulation ability further moderated this mediation effect of service employees' experienced customer incivility on service performance through emotional exhaustion. These findings have theoretical implications for employees' experienced customer incivility and emotion regulation ability research and provide managerial implications for practitioners. Conclusions - This study empirically elaborated the previous model of service employees' experienced customer incivility and personal resource (e.g., emotion regulation ability) literature by presenting the findings that service employees' experienced customer incivility influences their service performance via emotional exhaustion and that emotion regulation ability effectively reduces this negative effect.
