Volume 8, Issue 4 (Iranian Journal of Ergonomics 2021)
Abstract
Background and Objectives: The proliferation of computers, along with the development of software and the Internet, has revolutionized the work and life of people with disabilities, including those with spinal cord injuries with limited mobility in the arms. The efficiency and usability of the aids provided to these people is very important; because they have more limitations than ordinary people. The purpose of this study was to compare the efficiency and usability of human-computer interface in cervical spinal cord injury with two biofeedback EMG methods based on computer games and without computer games.
Methods: The sample size was 20 participants (healthy and with spinal cervical lesions) who were selected regarding availability. The statistical population of the study (that was conducted 2019-2020) was spinal cord injury patients referred to spinal cord injury clinic in Tehran. Participants received three 30-minute sessions per week for 1 month of EMG biofeedback training and game-based biofeedback interventions. SPSS version 23 was used for data analysis.
Results: Results showed that participants considered using EMG biofeedback and game biofeedback as 75/8% and 72/0% usability. Over time, the “through put” numerical values of the variable decreased in healthy individuals and spinal cord injury. Also, the numerical values of this variable were lower in healthy individuals than in individuals with spinal cord injuries. The maximum reduction in numerical values of the “through put” variable appeared between the first and sixth sessions.
Conclusion: The EMG and gaming biofeedback system can be used for interaction and control such as computers, wheelchairs, and more.

Volume 10, Issue 4 (Iranian Journal of Ergonomics 2023)
Abstract
Objectives: Considering the role of human resources in every organization, it is very important to address issues that lead to the reduction of occupational injuries in the workplace, it is clear that preventing the occurrence of job burnout in improving people's mental health. It plays an important role. One of the topics that can be useful in reducing job burnout is the application of ergonomic knowledge and compliance with safety principles, which is the purpose of this research is to investigate the impact of workplace ergonomic principles on job burnout with the moderating role of safety culture.
Methods: The current research is descriptive survey research, the statistical population of this research is all the employees of Ilam Petrochemical Company, which was obtained by using the Cochran formula, and the sample size is equal to 310 people; The main tools for collecting information in this research include demographic profile questionnaires, ergonomic principles, job burnout, and safety culture. The validity of the questionnaire was confirmed by the professors using face and content validity methods, and the reliability was also confirmed using Cronbach's alpha coefficient. In this research, structural equations based on path analysis in SMART PLS software were used to analyze and test research hypotheses.
Results: The impact of ergonomic principles on the burnout of Ilam Petrochemical employees is negative and significant with coefficients (T = 12.26, R2 = -0.42), and the cultural impact of safety on burnout is also negative and significant with coefficients
(T = 14.07, R2 = -0.32). is, the test of the main hypothesis shows that safety culture moderates the effect of ergonomic principles on job burnout and causes more reduction of job burnout.
Conclusion: Compliance with the principles of ergonomics in the work environment and the existence of a safety culture in Ilam Petrochemical will reduce job burnout.

Investigate the Mediating Role of Job Burnout in the Relationship between Corona Anxiety and Occupational Stress among Employees of the Engineering and Construction Company in the Oil Industry
Mohammad Reza Omidi, Hadi Meftahi, Nabi Omidi,
Volume 11, Issue 1 (Iranian Journal of Ergonomics 2023)
Abstract
Objectives: Employees in the oil and gas industry face various anxieties. The occurrence of corona disease and its rapid spread may increase the anxiety level of these people. The aim of this study is to investigate the mediating role of burnout in the relationship between corona anxiety and work stress.
Methods: The present study is a descriptive survey conducted in 1400. The statistical population of this research is all operational employees of Engineering and Construction Company of Oil Industries; Cochran formula was used to obtain a sample size of 310 people; the main instrument used to collect information is Corona Anxiety Scale Questionnaire, Job Burnout Questionnaire and Questionnaire. In this research, path analysis in SMART PLS software was used to analyze and test the research hypotheses.
Results: Corona anxiety has a significant effect on job burnout with coefficients (T=11.22 = 0.42, R^2) and job stress with coefficients (T=9.24 = 0.48, R^2). The effect of burnout on job stress is also significant with coefficients (T=9.24 = 0.38, R^2). The VAF effect coefficient for the effect of corona anxiety on job stress with the mediating role of burnout is equal to 0.51 and its significance coefficient is 7.52. Therefore, the mediating role of job burnout between the two variables corona anxiety and job stress was confirmed.
Conclusion: Corona anxiety has a direct and indirect negative effect on employees, and the level of corona anxiety in different industries should be reduced to improve employee performance.
