Masoud Khosravipour, Payam Khanlari, Mohammad Reza Jafari,
Volume 9, Issue 1 (Iranian Journal of Ergonomics 2021)
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.

Investigating the Effect of Wearing Medical Gloves on Grip Strength and Manual Dexterity
Fakhradin Ghasemi, Rashid Heidarimoghadam, Payam Khanlari,
Volume 9, Issue 3 (Iranian Journal of Ergonomics 2021)
Abstract
Background and Objectives: Hospital and medical staff use medical gloves to protect themselves and their patients from infectious agents. Wearing gloves may reduce manual dexterity and grip strength and interfere with work performance. The aim of this study was to investigate the effect of wearing medical gloves on grip strength, manual dexterity, and perceived comfort.
Methods: 20 people (10 women, 10 men) participated in this study. Participants were tested in three gloveless modes, with latex gloves and with nitrile gloves with two tests, a 9-hole pegboard and a modified pegboard. Perceived comfort in working with gloves, wearing and removing gloves was also assessed using a subjective scale.
Results: The age range of participants was 20 to 40 years with an average of 29.45 years. There was a significant difference in manual dexterity between gloveless hands and nitrile gloves in the 9-hole pegboard test. In the modified pegboard test, gloveless hand manual dexterity was significantly different from both latex and nitrile gloves. The results also showed that wearing any type of glove significantly reduced the grip strength of individuals. The worst comfort rating was given to wearing gloves.
Conclusion: The results of this study showed that wearing gloves reduces manual dexterity and grip strength. A modified pegboard test is also recommended to assess the manual dexterity of medical gloves. Latex and Nitrile gloves are difficult to wear and should be considered in designs.

Volume 11, Issue 3 (Iranian Journal of Ergonomics 2023)
Abstract
Objectives: Signs and symbols are used to inform how different tools work. Considering that washing machines are a widely used device and tool in today's life, the present study was conducted to determine the level of comprehension of “Saraye-Irani” visitors regarding the symbols placed on Iranian washing machines.
Methods: The number of 300 people who referred to "Seraye-Irani" located in Qom city participated in this study. A researcher-made checklist based on the ISO 9186-1 2007 standard was used to collect the required data. After the checklist was approved by the experts, it was distributed among the participants and they were asked to write down the meaning of each symbol in front of it. The gathered data were analyzed in SPSS version 22 software using the Chi-square and Fisher's tests.
Results: The results showed that the symbol of "wrinkle-free washing" with a comprehension rate of 70% was the only symbol that the participants had a good comprehension of. However, the participants' comprehension of the other 13 symbols in question was below the standard level. The understanding of symbols of "extra rinse" (P=0.016), "cold water wash" (P=0.037), "child lock" (P=0.001), and "full power wash" (P=0.044) decreased with increasing age. Moreover, individuals with higher education levels had a better understanding of symbols (P=0.001).
Conclusion: Among the 14 symbols measured in the present study, only one symbol had an acceptable level of comprehension. Therefore, according to the widespread use of washing machines, to optimize the use of this tool, it seems necessary to design and implement the necessary training to familiarize and understand these symbols.

Determining the Mental Workload and Investigating Its Effect on Changing the Mood Components of Taxi Drivers in the City of Qazvin
Hanieh Abdi, Seyed Abolfazl Zakerian, Kamal Azam, Payam Khanlari Baniyarani,
Volume 11, Issue 4 (Iranian Journal of Ergonomics 2024)
Abstract
Objectives: Road accidents and related damages and casualties are among the most important concerns of today's societies. Mental workload is one of the main human factors that can cause other factors, such as stress and anger. The present study was conducted to investigate the mental workload and its effect on changing the components of drivers' moods.
Methods: A total of 88 tour taxi drivers from Qazvin City participated in this study to examine the desired components. The driving Activity Load Index was used to evaluate mental load and the Profile of Mood States questionnaire to measure drivers' mood components. Based on the designed scenario of driving on high-traffic roads, the desired variables were evaluated. To check the relationship between these variables, paired t-tests and Pearson correlation analysis were used in SPSS version 24 software.
Results: The mean scores of the drivers' work history and age were obtained at 46.60±10.12 and 13.47±9.39 years, respectively. The obtained findings showed that driving on high-traffic roads significantly increased the average mental workload of drivers (P<0.001). Growth in the drivers' mental workload led to a decrease in some mood components that had a positive effect, such as happiness (r=-0.143, P=0.157) and vitality (r=-0.646, P=0.050), while it resulted in a rise in the mood component of depression (r=0.020, P= 0.248).
Conclusion: Based on the findings of the study, it can be concluded that as driving continues, drivers experience a rise in mental workload. However, there was no correlation regarding the effect of this component on the mood components.
