The Effect of Participatory Ergonomic Interventions on the Level of Satisfaction and the Motivating Potential Score of Employees of a Medical Diagnostic Laboratory in Isfahan
Mohammad Sadeagh Sohrabi, Neda Mahdavi,
Volume 7, Issue 2 (9-2019)
Abstract

Background and Objectives: One of the most effective methods for managing ergonomic risk factors in the workplace is to involve employees in identifying and assessing ergonomic risk factors and ultimately designing and implementing interventions by themselves. Therefore, this study aimed to implement a participatory ergonomic program, focusing on the transfer of ergonomic knowledge to employees, and to examine the effects of interventions on the macroeconomic indexes.  
Methods: This semi-experimental interventional study was carried out in cooperation with all staff of one of the medical diagnostic laboratories in Isfahan (11 people) in 2017. A participatory ergonomic program was implemented based on the Occupational Health Clinics for Ontario Workers Inc. (OHCOW) Guide. Then, the differences in the level of macro ergonomic elements such as job satisfaction and increase in motivating potential score of employees were studied before and after the interventions resulting from participatory ergonomic program (OHCOW) in this work environment. The data was analyzed using SPSS 23.
Results: Job satisfaction before and after ergonomic interventions had no significant difference (a relative increase), but in one of the scales, namely organizational climate, there was a significant change (P=0.016). Also, the motivating potential score of employees after the intervention was significantly higher than before (P=0.013).
Conclusion: In this study, participatory ergonomics were used to improve some aspects of macro ergonomic elements. Based on the results of this study, participatory ergonomics can increase some job satisfaction scores and motivating potential score of employees. Finally, it is suggested that allocate a longer duration for intervention utilization.


Explain the Model of Optimizing the Relationship between Labor and the Industrial Environment Through Architectural Criteria
Mrs Laleh Nazari, Dr Azadeh Shahcheraghi, Dr Iraj Etessam,
Volume 9, Issue 3 (12-2021)
Abstract
Background and Objectives: Job satisfaction and improving employee performance due to direct relationships with individual and environmental factors is one of the most important issues in optimizing the industrial environment. Since the main lever of decreasing or increasing productivity is human resources, one of the issues that will engage the leading managers in the coming decade is trying to increase employee productivity. Regarding the disposal of some affairs to the private sector and lack of adequate health supervision, in some cases, we witness an increase in this disorder in our country. The physical environment of the built environment affects mental health directly and indirectly, meaning that the physical environment, such as the residence and workplace, is a place for human life and some of its psychological effects are unknown.
Methods: The purpose of this research is to explain the model optimization model of labor and the industrial environment through architectural standards. This research is an applied research. In this research, the opinions were gathered through interviews. Then using grounded theory and open, axial and selective coding, the model was developed. In the following, confirmatory factor analysis was used to examine the validity of the items by Lisrel software.
Results: The results showed that indices such as environmental and physical ergonomics, visual contrast of space, environmental psychology, spatial separation of space, attention to voice and color are influential.
Conclusion: Psychological comfort is an inevitable aspect of user satisfaction studies. These findings help designers, architects, planners, and facility managers to develop workplace design principles. 

Investigating the Anthropometric Fit of Scientific-Research Laboratory Technicians with Their Workstations: A Case Study in Hamedan University of Medical Sciences
Zohreh Karami, Zahra Naserzadeh, Neda Mahdavi,
Volume 10, Issue 4 (3-2023)
Abstract
Objectives: Musculoskeletal disorders (MSD) induced by work are common in laboratory jobs. One of the most important reasons for disorders is the lack of personal fit with a workstation. This study aims to evaluate the body posture of experts in scientific-research labs and explore their anthropometric fitness with workstations on the campus of Hamedan University of Medical Sciences in 2022.
Methods: To investigate the MSD prevalence associated with the work, it was used the Nordic questionnaire and, for evaluating the posture, the Novel Ergonomic Postural Assessment (NERPA) technique. Then, to check the compatibility of laboratory personnel with the workstations, some interventions were proposed to improve them.
Results: According to the findings, the highest amount of prevalence of pain over the past year was in the neck area, 68.7%, and waist area, 59.37%, respectively. To assess the body posture using the NERPA technique, the middle level of corrective actions as well as more research was required. Also, the highest score of the risk, i.e. 40.62%, was allowed to the neck. In most activities, there was not any match between the dimensions of the personal body and the workstation.
Conclusion: The results indicated that the prevalence of MSD symptoms is high among the experts in research laboratories, and the risk levels of ergonomic assessment are in the middle. It seems that the lack of anthropometric matches with the workstation generally has led to adverse work posture and thus, the prevalence of MSD disorders. So, providing anthropometric matches between people who work in research laboratories and their workstations is essential to reducing these disorders.
