Background: The agricultural sector is one of the most important sectors in production. The safety and health of farmers are important factors that can cause a significant increase in efficiency and productivity. The aim of this study was the assessment of musculoskeletal disorders (MSDs) using the OVAKO Working Posture Analysis System (OWAS) and evaluation of the effect of ergonomic training o...

A unified database platform capable of storing both motion captured data and information about these motions (metadata) is described. The platform stores large motion captured data in order to be used by different applications for searching, comparing, analyzing and updating existing motions. The platform is intended to be used to choose a realistic motion in simulation of production lines. It ...

In this paper we introduce a new group decision procedure that follows a recursive pattern. In the first stage, the members of a group show their opinions on all the individuals of that group, regarding a specific attribute, by means of assessments within the unit interval. Taking into account this information, some aggregation operators and a family of thresholds, a subgroup of individuals is ...

Cleaning is a highly physically demanding job with a high frequency of awkward postures and working environments as contributing risk factors. Participatory ergonomics is a method in which end-users take an active role in identifying risk factors and solutions. The aim of this study was to apply the participatory ergonomics method to identify cleaning problems and to evaluate the effect of a lo...

In this paper, we apply a comprehensive approach to evaluate and analyze potential physiological and subjective workload effects of the application of head-mounted displays (HMDs) during a typical 3.5 hrs assembly operation. The approach refers to physical as well as cognitive workload associated with HMDs. The methods for capturing and determining physiological workload include an analysis of ...

This article is the result of an Ergonomic Diagnosis in a study for a Specialization Course in Ergonomics. The research is being done in a public hospital in the city of Rio de Janeiro, where the target system is the radiology sector. For diagnosis purposes, subjective techniques were used, such as an open-ended survey, Corlett questionnaire and techniques for evaluating ergonomic risk such as ...

We propose 'trans-omic' analysis for reconstructing global biochemical networks across multiple omic layers by use of both multi-omic measurements and computational data integration. We introduce technologies for connecting multi-omic data based on prior knowledge of biochemical interactions and characterize a biochemical trans-omic network by concepts of a static and dynamic nature. We introdu...
