Ergonomic Assessment and Design of the Tower Crane Cabin Based on Anthropometric Dimensions of Iranian Operators
Mohammadreza Jannati, Hamed Aghaei, Taleb Askaripoor, Mehdi Khazaei, Ehsan Bayat Khalaji, Elahe Kazemi,
Volume 8, Issue 2 (Iranian Journal of Ergonomics 2020)
Abstract
Background and Aim: Despite the main role of cranes in advancing construction operations, however, accidents and occupational injuries resulting from their activities have become a critical issue. Recent evidence suggests that the cause of these problems may be associated with the absence of design of the interior space of the crane cabin, and the tasks of the operators, based on ergonomic principles. This study was conducted to assess the ergonomic risk of the tower crane operator’s activities and redesigning the dimensions and interior space of these cranes, based on the anthropometric dimensions of Iranian operators.
Methods: In this descriptive cross-sectional study, 30 male tower crane operators working on three major construction projects in Tehran were investigated. Initially, a multi-step approach was applied to define the problem, including: observing the working statuses, interviewing operators, Nordic Musculoskeletal Disorder Questionnaire, and rapid upper limb assessment (RULA) method. Then, using anthropometric data, the dimensions and interior space of the crane chamber were redesigned.
Results: The results of the rapid upper limb assessment method showed that the activities of tower crane operators were at high and very high-risk levels. Also, 85% and 38.5% of these people reported pain and discomfort in one of the nine areas of their body in the last 12 months and 7 days, respectively. In this study, the dimensions of the interior space of the redesigned tower crane cabin were obtained 160.8×144.1×199.7.
Conclusion: Based on the results of the study, it can be concluded that the current interior design of the tower crane cabin does not fulfill the needs of the operators. Hence, redesigning it appears essential to enhance human-machine compatibility, improve safety and productivity, and prevent musculoskeletal disorders (MSD).

Effect of Stress Inoculation Training on Occupational Stress, COVID Anxiety, Resilience, and Sleep Quality in Medical Staff During the COVID-19 Pandemic
Nadere Seyedahmadi, Alireza Heidari, Parviz Askari,
Volume 11, Issue 1 (Iranian Journal of Ergonomics 2023)
Abstract
Objectives: The present study aimed to assess the effect of stress inoculation treatment (SIT) on occupational stress, COVID anxiety, resilience, and sleep quality of healthcare workers.
Methods: The current study was conducted based on a pre-test-post-test design with the control group. The research community consisted of healthcare workers in Ahvaz, and the research participants included 40 cases who were selected by purposeful sampling based on inclusion and exclusion criteria. The research instruments were the COVID-19 anxiety scale, resilience scale, sleep quality scale, and job stress scale. The data were analyzed in SPSS software using univariate and multivariate covariance analysis.
Results: The results of the present study demonstrated F ratios of univariate analysis of covariance for sleep quality (F=304.08 and P<0.001), COVID anxiety (F=212.99 and P<0.001), resilience (F=152.37 and P<0.001) and job stress (F=124.59 and P<0.001).
Conclusion: Due to the effectiveness of stress inoculation training on the studied variables, this training seems necessary for the health and treatment staff.

status of Iranian schools in terms of ergonomics: a systematic review
Roghayeh Esmaili, Ali Askari, Mohsen Poursadeghiyan,
Volume 12, Issue 3 (Iranian Journal of Ergonomics 2024)
Abstract
:Background and Objectives
Various factors, including a lack of attention to the adaptation of educational spaces, can significantly impact the quality of education. Consequently, this study aims to comprehensively review an
analyze all research conducted on school ergonomics in Iran.

 Methods
A bilingual search was conducted in this study utilizing Persian keywords such as "student," "elementary, middle or high school," and "physical, environmental, and general ergonomics," along with their Latin equivalents. This search was performed across databases including Google Scholar, PubMed, Web of Science, and Scopus, covering the period from the inception of research in Iran until the year 1403 in the Persian calendar (2024). Subsequently, articles relevant to the topic were collected and examined according to the established criteria.

Results
Among the identified articles, only 30 were recognized as relevant to the study's objectives, focusing on physical, environmental, and general ergonomics. A comparison of these studies revealed an upward trend in musculoskeletal disorders, with many of these issues linked to ergonomic problems in schools, including the mismatch between students' body dimensions and the desks and chairs used, as well as improper carrying of school bags.

Conclusion
The poor ergonomic condition in Iranian schools, leading to an increase in musculoskeletal disorders among students. It is vital to evaluate these schools based on ergonomic standards and implement necessary enhancements. Furthermore, it is important to raise students' awareness about proper task performance and appropriate backpack usage.
