Cognitive representation of the comprehension test of safety warnings using multivariate methods

This paper presents a multivariate method to assess the comprehension of safety signs. The proposed method uses the MDS and Procrustes, to obtain a consensus perceptual map. The results show that the map allowed discriminating signs with high levels of comprehension from others. The safety signs have no statistical difference as depicted by Bootstrap Analysis.     

Ergonomic initiatives at Inmetro: measuring occupational health and safety

This work studies biomechanical hazards to which the workforce of Instituto Nacional de Metrologia, Qualidade e Tecnologia Industrial (Inmetro) is exposed. It suggests a model for ergonomic evaluation of work, based on the concepts of resilience engineering which take into consideration the institute's ability to manage risk and deal with its consequences. Methodology includes the stages of identification, inventory, analysis, and risk management. Diagnosis of the workplace uses as parameters the minimal criteria stated in Brazilian legislation. The approach has several prospectives and encompasses the points of view of public management, safety engineering, physical therapy and ergonomics-oriented design. The suggested solution integrates all aspects of the problem: biological, psychological, sociological and organizational. Results obtained from a pilot Project allow to build a significant sample of Inmetro's workforce, identifying problems and validating the methodology employed as a tool to be applied to the whole institution. Finally, this work intends to draw risk maps and support goals and methods based on resiliency engineering to assess environmental and ergonomic risk management.     

Inclusion of people with disabilities in the production system of a footwear industry

This article presents a study on the inclusion of people with disabilities (mainly mental impairment) in the workforce of a shoe company. The items that could impact on the success of inclusion were identified, and this included employees and other individuals taking part in the process. The inclusion process identified the interests, likes and dislikes of each employee with disabilities and correlated these with the activities available in the company. The case study evaluated the quality of the inclusion through interviews, questionnaires and an assessment of production efficiency. The results showed that inclusion did not adversely affect production, and highlighted that staff with disabilities do their work correctly. According to all employees interviewed, the inclusion of staff with disabilities improved the relationship of the boss with all of the staff and also led to the work environment being enhanced. The final evaluation is that the company's policy of inclusion succeeded.     

Including the people with disabilities at work: a case study of the job of bricklayer in civil construction in Brazil

The aim of this paper is to present the results of the evaluation of the job of bricklayer in the construction industry to determine the profile of workers with disabilities who could perform this function and what adjustments are needed. The methods and techniques used in the field study were: direct observation of the activities and the environment, interviews with bricklayers on building sites, a video and photographic record of tasks being carried out to analyze the job of bricklayer, software resources were used. This study set out the disabilities most commonly caused by work accidents in the civil construction industry and simulated the conditions of the individuals to determine whether they could perform the activities of this function and what adaptations are needed. It was observed that workers with hearing impairments could perform activities without any change in the workplace and individuals who had had a leg or foot amputated need to use appropriate prostheses to perform the activities of the function. Thus, it was shown that the activity of professionals with experience in Ergonomics is essential since, by the activity of gathering data and analysing the physical, cognitive and organizational requirements of jobs and by collecting data on and analysing the functional capabilities of the worker with a disability, adaptations to jobs can be adequately defined.     

Risk factors for incident carpal tunnel syndrome: results of a prospective cohort study of newly-hired workers

Carpal tunnel syndrome is one of the most costly upper extremity disorders in the working population. Past literature has shown an association between personal and work factors to a case definition of carpal tunnel syndrome but little is known about the combined effects of these factors with the development of this disorder. Few studies have examined these associations in longitudinal studies. The purpose of this paper is to identify risk factors for incident carpal tunnel syndrome in a longitudinal study of workers across a wide range of occupations.
