Proposal for training of workers and researchers as from the participatory return of research results in workers' health

This study streams from a perspective of Workers' Health as a field of intervention where worker's experience on the process of illness is essential to understand and generate changes in the work process, and to contribute to develop knowledge in this area. We intended to collaborate in the training of researchers and nursing workers as a means of contributing to amplify their knowledge related to work and health conditions. As a motto to promote dialogue between researchers and workers, we organized workshops to discuss the results of an epidemiological study on the work-health relationships in nursing. Ten workshops were conducted at two federal public hospitals, in the city of Rio de Janeiro, Brazil. The main aspects discussed during the workshops revealed (i) work nuances for which the questionnaire was not sufficiently sensitive, (ii) some associations between different aspects of the survey, dealt with in the questionnaires, and (iii) recognition that some aspects shown in the epidemiological results were experienced at work. One can appreciate that the proposal presented here contributed to the training of researchers and workers, amplifying their knowledge and contributing to the development of the activity.     

Evaluation of objectivity, reliability and criterion validity of the key indicator method for manual handling operations (KIM-MHO), draft 2007

Upper extremity musculoskeletal symptoms and disorders are common in the working population. The economic and social impact of such disorders is considerable. Long-time, dynamic repetitive exposure of the hand-arm system during manual handling operations (MHO) alone or in combination with static and postural effort are recognised as causes of musculoskeletal symptoms and disorders. The assessment of these manual work tasks is crucial to estimate health risks of exposed employees. For these work tasks, a new method for the assessment of the working conditions was developed and a validation study was performed. The results suggest satisfying criterion validity and moderate objectivity of the KIM-MHO draft 2007. The method was modified and evaluated again. It is planned to release a new version of KIM-MHO in spring 2012.     

Designing dynamic distributed cooperative Human-Machine Systems

The paper presents a new approach to the development of cooperative human-machine systems in the Transportation domain which is currently researched in the European project D3CoS. A necessary precondition for the acceptance of cooperative human-machine systems with shared control is the confidence and trust of the user into the system. D3CoS tackles this important issue by addressing the cooperative system as the object and the target of the system development process. This new perspective, along with corresponding innovative methods, techniques and tools, shall allow the identification of optimal task and authority sharing approaches supported by intuitive human-machine interaction and user interfaces at an early stage of system development. This will support powerful teamwork between humans and machines or between machines and machines that is transparent, intuitive and easy to understand. The paper describes the research dimensions for the development of the methods, techniques and tools as well as first results.     

Issues concerning scientific production of including people with disabilities at work

This article presents the results of a survey carried out on leading periodicals in the areas of Ergonomics, Physiotherapy and Occupational Therapy, the aim of which was to identify scientific publications on the inclusion at work of people with disabilities. The survey of articles published on this topic in the following journals was conducted in December 2010: Applied Ergonomics, Ergonomics, the International Journal of Industrial Ergonomics, Disability and Rehabilitation, and the Journal of Occupational Rehabilitation. The survey covered issues published between 2000 and 2010 and was conducted electronically using the CAPES Periodicals Portal. To collect the articles, it was necessary to check the articles published in each of the issues of each volume of these periodicals. This is how the articles on the topic in question were found. There were 27 articles on the topic of inclusion at work of people with disabilities, of which 13 were published in the Journal of Occupational Rehabilitation and 12 in Disability and Rehabilitation. Thus, it is clear that the issue in question is still a subject that is seldom dealt with in these publications and it is noted that only two articles were published in Ergonomics journals in this period, thus confirming the paucity of scientific publications on this subject.     

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.     

Health and safety of students in vocational training in Quebec: a gender issue?

Health and safety issues in a vocational training center were explored in this study. Several sources and methods were used: group interviews with students in traditionally female [F] and male [M] trades, i.e. hairdressing (7 F) and automated systems electromechanics (8 M, 1 F); self-administered questionnaires on injuries sustained at the school; observations of activities in these programs; and analysis of ministerial documents. Findings indicate that the partially divergent ways that OHS is addressed in these programs cannot be explained only by the specific characteristics of the two trades. Some aspects put female students in hairdressing at a disadvantage: status accorded to OHS in the study programs, learning activities, and conditions for learning and managing prevention and injuries. The discussion focuses on a gender-differentiated analysis, the importance of improving the way OHS is addressed in the programs, in particular, those primarily involving female students, and the need to pursue research. In addition, the results from individual interviews with women (5 F) training for non-traditional trades lead to discussion on the interrelated effects of sex-based gender and professional gender.     

Metrology and ergonomic mensuration parameters

This poster intends to show how measurement, its concepts and methods are decisive to the ergonomic praxis and why their agents should be aware of how incertainty can be taken in the process in order to increase the accuracy of measurement and findings.     

Product evaluation based in the association between intuition and tasks

This paper explores the importance of researching the intuitiveness in the product use. It approaches the intuitiveness influence for users that already had a visual experience of the product. Finally, it is suggested the use of a table that relates the tasks performed while using a product, the features for an intuitive use and the performance metric "task success".
