Purpose: The purpose of this study is to identify the effects of job demand and recovery experience from job stress on job embeddedness among workers in the service industry. Methods: The participants were 223 workers from the service industry in P and Y Cities with the help of a structured self-report questionnaire, administered between July 10 and August 20, 2017. The data were analyzed using descriptive statistics, t-test, ANOVA, $Scheff{\acute{e}}$ test, Pearson correlation coefficients and stepwise multiple regression. Results: There were significant differences in job embeddedness in terms of satisfaction with salary, continuous service, perceived stress level and the perceived health status of the subjects. There were significant positive correlations between role clarification in job demands (r=.55), recovery experience from job stress (r=.27) and job embeddedness. From the multiple regression analysis, the most significant factors affecting job embeddedness were found to be role clarification in job demands (${\beta}=.47$), recovery experience from job stress (${\beta}=.23$), and perceived stress level (${\beta}=.18$). These variables explain 34.0 % of the total variance in job embeddedness. Conclusion: In order to increase job embeddedness among workers in the service industry, it is necessary to prepare measures to increase recovery experience from job stress and to decrease role clarificationin job demand, and perceived stress level.

The purpose of this study is to understand the influence factors of job stress and resilience to recovery in an organization on job satisfaction and immersion in the organization. For this reason, we developed a questionnaire scale based on previous research, and conducted a questionnaire survey of the sales staff of company S. As a result of the analysis, it was found that job stress had a significant effect on job satisfaction, and job stress had a significant effect on recovery elasticity. It was shown that recovery elasticity affects job satisfaction and organizational immersion, and that job satisfaction affects organizational immersion, but the hypothesis that job stress has a significant effect on organizational immersion was rejected. In addition, it was found that recovery elasticity mediates the relationship between job stress, job satisfaction, and organizational immersion. The results of this study are expected to be used as guidelines for various practical plans that can improve the resilience of recovery as well as stress management of organizational members in the organization.

Patch recovery attempts to derive a more accurate stress filed over a particular element than the finite element shape function used for that particular element. Elements that have a free edge being the boundary to the structure have particular stress relationship that can be incorporated to the stress field to improve the accuracy of the approximation.

To investigate the relationship between cold stress and the activity of ascorbate peroxidase(APX), dehydroascorbate reductase (DHAR), mRNA expression level of two enzymes, hydrogen peroxide content was studied in lettuce leaves under stress condition imposed by cold stress at $4^{\circ}C$ for 24 hr in the dark and following recovery at $20^{\circ}C$ from cold stress. Hydrogen peroxide content increased gradually in lettuce leaves during cold stress, but decreased slightly following recovery from cold stress. Soluble protein content, however, decreased gradually during cold stress, and then rapidly returned to normal levels following recovery. Total chlorophyll content decreased gradually during cold stress, and then keep constant following recovery. The patterns of chlorophyll a and b content similar to that of total chlorophyll content, and carotenoid content didn't change. The ratio of chlorophyll a and total chlorophyll was increased during cold stress, but decreased with rapid during cold stress, and then the ratio returned to normal levels following recovery. During cold stress, the activity of APX and DHAR in the lettuce leaves increased dramatically, and also transcript levels of mRNA of APX and DHAR, as determined by probing 32P-labeled single stranded RNA of APX and DHAR, highly increased and returned to normal levels following recovery, respectively. Relationship between APX and DHAR activity and hydrogen peroxide highly related ($R^2$=0.8715 and 0.8643), whereas between hydrogen peroxide and total chlorophyll content and soluble content related reversely ($R^2$=0.5021 and 0.8915).

Fiber-reinforced composites not only have a direction of thermal expansion coefficient, but also inevitably suffer thermal stress effects due to the difference between the manufacturing process temperature and the actual use temperature. The damage caused by thermal stress is more prominent in the case of thick composite laminates, which are increasingly applied in the aerospace industry, and have a great influence on the mechanical function and fracture strength of the laminates. In this study, the dimensional reduction and thermal stress recovery theory of composite beam structure having high slenderness ratio is introduced and show the efficiency and accuracy of the thermal stress comparison results between the 3-D finite element model and the dimension reduction beam model. Efficient recovery analysis study will be introduced by reconstructing the thermal stress of the composite beam section applied to the thermal environment by constructing the dimensional reduction modeling and recovery relations.

A cost-effective magnetic-coupled AC-PDP sustain driver with low switching loss is proposed. The transformer reduces current stress in the energy recovery switches which affects circuit cost and reliability. The turns-ratio can be used to adjust the sustain pulse slopes which affect gas discharge uniformity. Dividing the recovery paths prevents abrupt changes in the output capacitance and thereby switching losses of the recovery switches is reduced. In addition, the proposed circuit has a more simple structure because it does not use the recovery path diodes which also afford a large recovery current. By reducing the current stress and device count in the energy recovery circuit, the proposed driver may have decreased circuit cost and improved circuit reliability.

Purpose: This study was conducted to determine the factors affecting a hypothetical model of testing for general hospital nurses' job embeddedness. Methods: Data were collected from August 20 to September 19, 2021, by a self-administered questionnaire answered by 428 general hospital nurses. The data were analyzed by SPSS and AMOS. Results: Nine of the hypothetical model's 12 hypotheses were supported by the data collected from all participants. The test results indicate that ego resilience, subjective career success, and recovery experience from job stress directly affect participants' job embeddedness. Nurses' work environments were reported to affect ego resilience and subjective career success, while at the same time ego resilience and subjective career success affected the participants' job embeddedness. Work-life balance was found to affect ego resilience and ego resilience affected subjective career success, and at the same time subjective career success directly affected participants' recovery experiences from job stress and job embeddedness. Of these variables, subjective career success had the strongest direct effect on participants' job embeddedness. Work-life balance affected the participants' recovery experiences from job stress, and their recovery experiences from job stress were found to directly affect job embeddedness. Conclusion: These results suggest that different management strategies to enhance hospital nurses' job embeddedness should address nurses' ego resilience, subjective career success, and recovery experiences from job stress.

Solution-processed oxide thin-film transistors (TFTs) have garnered great attention, owing to their many advantages, such as low-cost, large area available for fabrication, mechanical flexibility, and optical transparency. Negative bias stress (NBS)-induced instability of sol-gel IGZO TFTs is one of the biggest concerns arising in practical applications. Thus, understanding the bias stress effect on the electrical properties of sol-gel IGZO TFTs and proposing an effective recovery method for negative bias stressed TFTs is required. In this study, we investigated the variation of transfer characteristics and the corresponding electrical parameters of sol-gel IGZO TFTs caused by NBS and positive bias recovery (PBR). Furthermore, we proposed an effective PBR method for the recovery of negative bias stressed sol-gel IGZO TFTs. The threshold voltage and field-effect mobility were affected by NBS and PBR, while current on/off ratio and sub-threshold swing were not significantly affected. The transfer characteristic of negative bias stressed IGZO TFTs increased in the positive direction after applying PBR with a negative drain voltage, compared to PBR with a positive drain voltage or a drain voltage of 0 V. These results are expected to contribute to the reduction of recovery time of negative bias stressed sol-gel IGZO TFTs.
