Abstract
Background and Objectives: Increasing the retention of health care workers in the context of Covid-19 expansion is one of the most important challenges for the health care systems. To design a strategy to maintain health care workers, it is necessary to identify the factors influencing willingness to work or leave the job among health care workers. This study aimed to identify the factors affecting the willingness to work or leave the job among health care workers during the Covid-19 pandemic.
Methods: To identify relevant publications, the online Databases including Scopus, PubMed, Web of Science, and ProQuest were searched on October 20, 2020. Based on the inclusion criteria, only studies that investigated the factors influencing willingness to work or motivation to leave the job among health care workers during the Covid-19 pandemic were included.
Results: Of the 610 studies found through searching, after deleting similar and unrelated studies, a number of 10 cross-sectional articles with a sample size of 15834 subjects were selected. Obtained findings indicated that the willingness to work among health care workers ranged from 61% to 98.7% and averaged 83.5%. The results of studies showed that job factors such as work experience, previous work experience in emergency time or Covid-19, workload, cooperation between employees, the relationship between employees and managers, access to personal protective equipment, and welfare facilities were significantly proportional to the willingness of health care workers to work.
Conclusion: The results of this study showed to design a strategy to maintain the health care workers during the Covid-19 pandemic, a broad range of occupational and psychological variables should be considered. Due to the limited number and quality of studies and the extent of influential variables, more studies are needed in this field.

Abstract
Objectives: The primary aim of this study is to examine the impact of carbon dioxide concentrations in the air on thermal comfort, cognitive performance, and heart rate among healthcare workers while they engage in their duties within therapeutic environments. These settings are often characterized by high occupancy, inadequate ventilation, underground locations, limited natural light, and exposure to pollutants.
Methodology: In this laboratory-based research, 20 employees from a specialized clinic were randomly assigned into two groups of ten. They were exposed to varying levels of carbon dioxide at a controlled temperature of 25 degrees Celsius: one group experienced 1100 ppm with adequate ventilation, while the other was subjected to 1800 ppm without ventilation. Key parameters such as heart rate, thermal comfort (assessed using the ASHRAE standard questionnaire), and cognitive performance (measured through the MOCA test) were recorded. The collected data were analyzed using multivariate analysis of covariance (MANCOVA).
Results: The statistical analysis revealed significant effects of cognitive performance and carbon dioxide levels (1800 ppm vs. 1100 ppm) on thermal comfort (F(1,15)=13.257, p<0.05 and F(1,15)=16.694, p<0.05). Furthermore, both the carbon dioxide levels and the gender of participants significantly influenced the heart rate of healthcare workers in their work environments (F(1,15)=53.381, P<0.05 and F(1,15)=9.642, p<0.05). Specifically, individuals exposed to 1800 ppm of carbon dioxide reported a thermal dissatisfaction score that was 0.878 units higher and exhibited a heart rate that was 9.25 beats per minute greater compared to those exposed to 1100 ppm..
Conclusion: The findings underscore the importance of continuous air quality monitoring in workplace settings. Such measures can enhance thermal comfort levels, improve cognitive performance, and mitigate health risks for healthcare workers engaged in their professional activities.
