A wide variety of observational methods have been developed to evaluate the ergonomic workloads in manufacturing. However, the precision and accuracy of these methods remain a subject of debate. The aims of this study were to develop biomechanical methods to evaluate ergonomic workloads and to compare them with observational methods. Two observational methods, i.e. SCANIA Ergonomic Standard (SE...

This study aimed to perform an ergonomic analysis in a fiberglass parts factory. For this purpose, was used the methodology of Ergonomic Work Analysis (EWA). At the end of the study it was possible to identify some ways to the development of improvements in order to contribute to the transformation of working conditions in the sector analyzed.

Ample evidence suggests that social chemosignaling plays a significant role in human behavior. Processing of odors and chemosignals depends on sniffing. Given this, we hypothesized that humans may have evolved an automatic mechanism driving sniffs in response to conspecific sniffing. To test this, we measured sniffing behavior of human subjects watching the movie Perfume, which contains many ol...

This paper will discuss the benefits of sharing data between discrete event process simulation and ergonomic workplace assessment using software developed by Deneb Robotics Inc. A modeling exercise has been developed to illustrate the integration of ergonomic and discrete event process modeling. This paper will provide an overview of ergonomic and process modeling, a summary of features and fun...

Due to the cost and time benefits associated with patients and physicians, outpatient surgeries continue to become more and more popular over time. With the increase in the number of office-based surgical procedures, the prevalence of work-related musculoskeletal disorders (WMSDs) associated with office-based surgeries has been reported. The purpose of this pilot study is to ergonomically evalu...

This paper introduces a new version of Ergonomic Criteria for HVEIs which have been tested for validity. An assignment experiment (Ergonomic Criteria X Usability Problems) has been conducted to ensure the appropriate understanding of the different criteria. The results of this study identify the criteria that are well understood and the ones that need further improvement.

Throughout the COVID-19 pandemic, students face intolerable mental and physical discomfort when taking online classes, directly impacting their learning motivation academic performance. Related studies indicated that had negative sentiments regarding learning. This may be an alarming notion for students, particularly ability participation in school. To overcome this nuisance, primary objective ...

BACKGROUND Sonographers' perceptions of ergonomic and work-related pain problems at work have so far mostly been researched in quantitative studies by questionnaires. There is a need of experience-based research to deepen the knowledge about how sonographers perceive ergonomic problems at work. Therefore, the aim of this qualitative study was to describe sonographers' perceptions of ergonomic p...

Management of Tata Steel, the largest steel making company of India in the private sector, felt the need to develop a framework to determine the levels of ergonomic performance at its different workplaces. The objectives of the study are manifold: to identify and characterize the ergonomic variables for a given worksystem with regard to work efficiency, operator safety, and working conditions, ...
