This study investigated small and medium-sized hospital workers' knowledge of COVID-19, the infection-control-related fatigue and stress levels, and the factors that impacted their performance during the COVID-19 pandemic. Using a cross-sectional design, data were collected from 137 hospital workers from four small and medium-sized hospitals in S and C cities. Data were analyzed using descriptive statistics, a t-test, analysis of variance(ANOVA), Pearson's correlation coefficient, and multiple linear regression analysis. Small and medium-sized hospital workers' knowledge of COVID-19 revealed a correct answer rate of 66%. An average of 3.00 points out of 4 for infection control performance and 3.32 and 3.17 points out of 5 for infection-control-related fatigue and stress, respectively, were found. The level of knowledge regarding COVID-19 significantly differed by age and marriage (p<0.05), while infection control performance significantly differed by age, marriage, and infection control education experience (p<0.05). Infection-control-related fatigue and stress differed depending on the COVID-19 control education experience, economic and social prejudice, and fear of discrimination. There were positive correlations between knowledge and infection control performance, and infection control performance and infection-control-related fatigue and stress (p<0.001). This study showed that the factors that affected small and medium-sized hospital workers' performance included knowledge of "environmental management," "difficulties due to new role requirements," "presence or absence of infection education experience," "job type," and "age." These results suggest that practical and detailed education programs should be systematically developed and implemented for effective infection control.

Purpose: This study was to evaluate the effects of a comprehensive life style modification program on glycemic control and stress response in type 2 diabetes. Method: The participants(n=34) with type 2 diabetes were divided into either a usual care(control) or treatment(experimental) group. The experimental group(n=21) received a program that was based on a comprehensive life style modification protocol at a weekly meeting for 16 weeks. They also participated in individually prescribed exercise and diet along with stress management and self monitoring. The participants were followed for 6 months, during which postprandial glucose, HbA$_{1C]$, and stress response inventory were measured. Result: The experimental group showed a significant lower postprandial glucose and stress response compared to those of the control group. However, there was no significant change in the HbA$_{1C]$ value in either group. Conclusions: These results suggest that a type 2 diabetes comprehensive lifestyle modification program may lead to clinical improvement in glycemic control and reduce the stress response.

Background: The importance of infection with COVID-19 is being emphasized in dentistry with high risks such as aerosols. The purpose of this study is to investigate the knowledge and practice of infection control, stress and coping, and turnover of dental hygienists. Methods: Questionnaire was conducted knowledge and practice of infection control, occupational stress and coping, turnover. Survey data was investigated about 149 dental hygienists from February to March 2021 Data were analyzed t-test, ANOVA, Pearson's correlation using statistical programs of PASW Statistics ver. 21.0. Results: Regarding occupational stress, relationship conflict was higher in the group with less than 2 years of experience (p<0.05). Job anxiety, organizational system, inadequate compensation, and workplace culture were highly surveyed in the 3 to 5 year of experience. The group with more than 6 years of experience had the highest perception of lack of job autonomy (p<0.05). The group with higher knowledge of infection control had lower mean inappropriate rewards and stress (p<0.05). The group with high infection control performance had a lower average in items such as job instability, organizational system, inadequate compensation, workplace culture, and stress. And problem-focused coping ability was found to be high (p<0.05). Infection control knowledge and performance were positively correlated (r=0.251, p<0.01), infection control practice and stress were negatively correlated (r=-0.264, p<0.01), and stress and emotional coping were positively correlated (r=0.367, p<0.01). Stress was positively correlated with turnover rate (r=0.549, p<0.01). Conclusion: Infection control training was required to reduce occupational stress. Occupational stress was highly correlated with turnover, a holistic and systemic organizational operation and improvement of the quality of medical care were required to reduce stress.

This study examines the mediating effects of social support on 1) the relationships between acculturative stress and depression/anxiety and 2) the relationships between emotional control and depression/anxiety in children from multicultural families. Pearson's correlations between variables were analyzed, and hierarchical regression analyses were conducted to identify direct and indirect effects of acculturative stress, emotional control, and social support on children's depression/anxiety. The sample included a total of 199 primary school students in grades 3 to 6 who lived in the Gwangju or Chonnam regions of Korea. First, there were positive correlations between acculturative stress and depression/anxiety and negative correlations between emotional control and social support. Second, social support from both peers and teachers partially mediated the relationships between acculturative stress and depression/anxiety. Third, social support from peers fully mediated the relationships between emotional control and depression/anxiety, and that from teachers partially mediated these relationships. The results suggest that social support from peers and teachers may reduce depression/anxiety in multicultural children as a mediating variable.

The effects of the ethanol extracts from Gynostemma pentaphyllum (GP extracts) on body weights, grip strengths, endurances and catecholamine levels after electric footshock (EF) stress in mice and rats were investigated. The animals were treated with GP extracts (50 mg/kg/day, p.o.) for 21 days before exposure to EF (duration and interval 10 sec for 3 min, 2 mA) once a day. The increases in body weights were delayed by 13.1% of the control levels by EF-induced stress in mice, which were recovered to 24.1% of the control levels in GP extract-treated groups. The grip strengths were significantly decreased by EF stress in mice and the EF-stressed groups treated with GP extracts increased grip strengths to 115.2% compared to control levels. The endurance times by forced swimming, which reduced significantly by EF stress, were also maintained similar to control levels by GP extracts in rats. In addition, the levels of norepinephrine and epinephrine in serum and brain, and dopamine in brain were significantly increased to 17.5-95.0% of the control levels after exposure of EF stress in mice. However, EF stressinduced increases in norepinephrine and epinephrine in serum were reduced to 17.1-17.3% of the control levels by treatments of GP extracts, and those in dopamine, norepinephrine and epinephrine in brain were also reduced to 5.0-19.5%. These results suggest that GP extracts showed the protective effects on EF stress-induced physiological functions and can be developed as the promising anti-stress agents.

Psychological stress is a growing issue in work stress research because work stressors are closely related to depression； and depression, in turn, decreases organizational effectiveness. Considering such causal relationships of work stress, a comprehensive source to control work stress is needed for worksite mental well-being. This study was conducted to identify how social support at work controlled work stress and which characteristics of social support were effective on work stress reduction. The study participants were 240 workers employed in a public hospital in Georgia, U.S.A self-administered survey was given to employees with their pay slips, and followed by a hospital wide voice reminder for 7 days. Surveys were conducted over a 20-day period. The questionnaires asked about job demands, job control, social support at work, depression, job performance, absenteeism, and demographics. The social support construct was structured on the source of support at work and the kinds of support were provided. Statistical analyses were conducted in the structural equation modeling approach. Social support at work was directly related to high job control, low depression, and high job performance. High score of social support at work were significantly associated with high job control, low depressive symptoms, and high job performance. By source of support, only organizational support was positively related to high job control. Organizational support was more effective than supervisor and coworker support. Any stressors and their outcomes were not differenciated by the kinds of support. This result indicated that job control was influenced more by the source of support than the kinds of support provided at work； and the most efficient source of support was the organization. Organizational support was a strong factor in improving workers" perceived controllability of their jobs from a work stress reduction perspective.tive.

Pre-drainage of groundwater in the roof aquifer by boreholes is the main method for prevention of roof water disaster, and the drop in the water level during the drainage leads to the variation of the local stress in the overlying strata. Based on a multitude of boreholes for groundwater drainage from aquifer above the 1303 mining face of Longyun Coal Mine, theoretical analysis and numerical simulation are used to investigate the local stress variation in the process of borehole drainage. The results show that due to the drop in the water level of the roof aquifer during the drainage, the stress around the borehole gradually evolved. From the center of the borehole to the outside, a stress-relaxed zone, a stress-elevated zone, and a stress-recovered zone are sequentially formed. Along with the expansion of drainage influence, the stress peak in the stress-elevated zone also moves to the outside. When the radius of influence develops to the maximum, the stress peak position no longer moves outward. When the coal mining face advances to the drainage influence range, the abutment pressure in front of the mining face is superimposed with the high local stress around the borehole, which increases the risk of stress concentration. The present study provides a reference for the stress concentration caused by borehole drainage, which can be potentially utilized in the optimal arrangement of drainage boreholes in underground mining.
