PURPOSE We sought to compare the ability of novice operators to provide artificial ventilation using a standard facemask and a new ergonomically designed facemask. Whether or not proper technique was used was also assessed. METHODS Thirty-two allied-health students used both masks in random crossover fashion to ventilate an airway trainer. Breaths were delivered by a mechanical ventilator and...

Background: Musculoskeletal symptoms are the main cause of loss of working time, and increase in labor costs. Poor posture is the most important risk factor for work-related musculoskeletal symptoms. This study aimed at evaluating the role of ergonomic risk factors in different surgical (open surgery, laparoscopy, and microsurgery) in the frequency or resonance frequency of musculoskeletal symp...

Introduction: Musculoskeletal disorders (MSDs) are most important work-related injuries and debilities in developed and developing industrial countries. In the recent years, the rate of injuries and MSDs in car montage industries compared with other industries was so more. Therefore, the purpose of present study was focused on ergonomic assessment of sina car montage industry employees’ workin...

The physical tasks of workers are demanding, particularly when performed long-term in unsuitable working position, with high frequency, heavy load, after injury, developing damage health or reduced performance due to advanced age. Work-related musculoskeletal disorders (WMSDs) result from overuse develop over time. Work activities, which frequent and repetitive, activities awkward postures, cau...

World economic growth is directly proportional to the increase in building sector. The sector accounts for 31% of global energy consumption. Humans also increasingly recognize importance health aspects, convenience indoor quality, and user safety building. This study combines concepts green assessment ergonomics produce a new framework called ergonomic condition that not only focuses on use, qu...

Concerning that many production tasks are still mainly manual, examining typical workloads at production sites is a challenging task. Currently, workspace design is evaluated by experts, filling ergonomic evaluation sheets by estimation of postures and loads. The use of motion capture systems could improve the evaluation process of body postures to achieve accurate data and detailed results on ...
