Companies are making design changes by improving product quality and function to succeed while meeting customer requirements continuously. Design changes are changing the product BOM's amount, item, specification, and shape while causing a change in the product's structure. At this time, the problem of inventory exhaustion of parts before design change is a big topic. If the inventory exhaustion fails, the pieces before the design change become unused and are discarded, resulting in a decrease in asset value, and the quality cost of the design change affects the company's profits. Therefore, it is necessary to decide to minimize quality costs while minimizing waste inventory costs at the time of application of design changes. According to the analysis, priorities should be prioritized according to urgency because the quantity of items before the design change affects the applied lead time.

The main aim of this investigation is to explore the relationships between emotional exhaustion, depersonalization, personal accomplishment, and job satisfaction among employees working in the banking sector. A total of 214 respondents were surveyed for the purpose of this investigation and selected randomly from different banks located in the Kingdom of Saudi Arabia (K.S.A.). Job Burnout Inventory developed by Maslach and Jackson (1981) was taken into consideration to assess emotional exhaustion, depersonalization, and sense of personal accomplishment, and job satisfaction scale was used to measure the degree of satisfaction level of the employees. The collected data were analyzed by means of descriptive and inferential statistics with the help of statistical Package for Social Sciences (SPSS). The most eye-catching findings of the investigation revealed that emotional exhaustion had the greater mean as compared to depersonalization and personal accomplishment. The inverse significant correlation has been observed between emotional exhaustion, depersonalization, and job satisfaction while positive and significant relationship was observed between personal accomplishment and job satisfaction. Further, the result of the investigation from regression test indicates that the relationship existed between emotional exhaustion, depersonalization, personal accomplishment, and job satisfaction among employees working in the banking sector in the Kingdom.

Purpose: This study explored the mediating role of resilience between post-traumatic stress and emotional exhaustion in nurses during the COVID-19 pandemic. Methods: The data were collected from 193 nurses working at a hospital in Daegu from October 16 to 30, 2020, in the middle of the COVID-19 pandemic. Participants conducted self-reported surveys of post-traumatic stress (Impact of Event Scale-Revised Korean version), emotional exhaustion (Maslach Burnout Inventory), and resilience (Korean Resilience Quotient Test). The data were analyzed using descriptive statistics, frequency, t-tests, Mann-Whitney U tests, Kruskal-Wallis tests, Pearson correlation coefficients, and multiple regression. Mediation analysis was performed using the Baron and Kenny method and Sobel test. Results: The mean scores for post-traumatic stress, resilience, and emotional exhaustion were 16.18±16.18, 183.41±18.29, and 32.64±9.66, respectively. A higher level of post-traumatic stress was associated with lower resilience (r=-.20, p=.004) and with higher emotional exhaustion (r=.33, p<.001). A higher level of resilience was associated with lower emotional exhaustion (r=-.35, p<.001). The resilience was confirmed to have a partial mediating effect in the relationship between post-traumatic stress and emotional exhaustion, verified by the Sobel test (Z=2.31, p=.02). Conclusion: Resilience had a partial mediating effect in the relationship between post-traumatic stress and emotional exhaustion. Thus, nurses should develop individual strengths to reduce emotional exhaustion, and managers should also make efforts to increase the nurses' resilience. It is also necessary to develop and apply a program to strengthen nurses' resilience.

Purpose: This Study was to examine to applicability of the Maslach Burnout Inventory on measuring burnout of the nurses who works in Korean university hospitals. Methods: The sample included 200 nurses and nurse managers. We used 22-item Maslach Burnout Inventory to evaluate the reported burnout. We evaluated the convergent validity through the factor analysis, and evaluated the discriminant validity through the Pearson's correlation analysis. Also, we evaluated the reliability for three subscales of Maslach Burnout Inventory with the Cronbach's ${\alpha}$, which assesses the internal consistency. Results: Factor analysis revealed three factors being extracted from the 22-item Maslach Burnout Inventory, and item loading for each factor is higher than 0.5. Therefore, the Maslach Burnout Inventory demonstrated high convergent validity. Also, emotional exhaustion, personal accomplishment, and depersonalization showed low correlation leading to the conclusion that there was discriminant validity. The Cronbach's ${\alpha}$ coefficients in the 22-item Maslach Burnout Inventory and three subscales were higher than 0.7. Conclusion: Maslach Burnout Inventory can be used as a valid instrument to measure the burnout level of the nurses working in Korean university hospitals.

The purpose of this study was to 1) investigate the characteristics of burnout of Korean elementary school students and 2) develop and validate the Korean Academic Burnout Scale-Elementary School Students (KABS-ESS). Fifty-one behavioral descriptions of burnout extracted through a preliminary survey, focus group interview, and literature review were administered to a sample of 531 elementary students of the 4th to 6th grade in Gyeonggi Province. The results of an exploratory factor analysis indicated that the structure of the burnout of Korean elementary school students consists of seven factors (i.e., inefficacy, avoidance, cynicism, emotional exhaustion, physical exhaustion, antipathy and cognitive exhaustion), and this structure of final 28 items was confirmed by the confirmatory factor analysis. The KABS-ESS showed a correlation of .771 with a representative academic burnout scale, Maslach Burnout Inventory-Student Survey, and -.561 with the academic engagement scale, indicating that both convergent and discriminant validities were confirmed. Furthermore, all fit indices of the structural equation model of the Schaufeli and Bakker's job demands-resources in an academic setting were satisfactory, and the possibility of the validity generalization of the model was supported. The demand variables predicting academic burnout and engagement were academic overload and parental pressure, while self-resilience, self-regulated learning strategies, and parental and the teacher's support were identified as the resource variables. Lastly, the implications and future direction of the present study were discussed.

Objectives The purpose of the present study was to examine the relationship between the chronotype and the burnout, so we investigated the mediating effects of the mediators such as perceived stress, stress response, and depression. Methods Employees working at Incheon Customs conducted a mental health self-examination through the internet. Among them, 174 people who agreed to the mental health survey participated in the study. Participants completed questionnaires including Composite Scale of Morningness (CSM), Center for Epidemiological Studies-Depression Scale (CES-D), Perceived Stress Scale (PSS), Stress Response Inventory (SRI), Maslach Burnout Inventory-General Survey (MBI-GS). Results Our results showed a higher degree of CES-D, SRI, exhaustion, and cynicism in evening and intermediate type compared to morning type, and a higher degree of professional efficacy in morning type compared to intermediate type. CSM was shown to have a direct effect on exhaustion and indirect effect through CES-D and SRI. CSM also had a direct effect on professional efficacy and had an indirect effect through the CES-D. However, CSM was found to have only indirect effects through the SRI for Cynicism. Conclusions In this study, individuals with evening type tend to experience a high degree of burnout (exhaustion, cynicism and professional efficacy) through the mediation effect of depression and stress response. Further study is necessary to reveal the effect of management of the depression and stress response in the employee with evening type.
