Autor(es): Rodrigues, Vitor; Rocha, Raoni
Resumo: Participatory ergonomics relies on the involvement of people to constitute or improve their work environments. The present study aims
to answer through a literature review how ergonomic interventions
are performed in these environments. The research focussed on workspace design and processes related to participative ergonomics. The
search in Scopus was performed for the period 2016 to 2020. From
200 articles, 28 were tabulated for content analysis encompassing the
themes of ergonomic approach modes, use of intermediate objects
and technological solutions adopted. The majority of the studies
found were inserted in hospital, office and maritime/port environments. The results show that ergonomics approaches face diverse
challenges: financial and time constraints, power asymmetries, experience levels, social, cultural and individual issues. Nevertheless, it sets
out to develop skills, activities, competencies, and to organise these
in a global and structured way. Further studies in a wide diversity of
databases are needed to follow up the analysis of such approaches
and conceptions of work activity.2022-01-01T00:00:00ZJob rotation as a legal requirement : analysis of the participatory approach in acceptance and workers’ perception at a meatpacking plant.Messias, Iracimara de AnchietaNascimento, AdelaideRocha, Raonihttp://www.repositorio.ufop.br/jspui/handle/123456789/168612023-07-03T19:32:02Z2022-01-01T00:00:00ZTítulo: Job rotation as a legal requirement : analysis of the participatory approach in acceptance and workers’ perception at a meatpacking plant.

Resumo: This article presents an experience of a participative approach prior to the implementation of
NR-36, which regulates work in meat and meat byproduct companies. Although the regulations provide
for worker participation in the processes of implementing job rotation, they do not explain how to do it. This
study was developed in 2017 in the livestock slaughtering sector of a company with 79 workers, using
two complementary methods: systematic and analytical observation of the real work (totaling 32 hours of
observation) in order to select the jobs that were primarily eligible for rotation, together with a survey of the
workers' perception of the level of acceptance of rotation in the selected jobs. At first, 72% of the workers
refused to accept the rotation. After inclusion and participation in the implementation process, 86% of the
workers in the dirty area and 64% in the clean area agreed to the rotation. The advantages of rotation that
most stood out included: the variability in work (30%), learning and gaining experience (40%), changes in
movements (35%), and physical rest (32%). By contrast, the disadvantages included: the fear of accidents
(30%) and the fear of change and of the unknown (25%). It can therefore be concluded that the
participatory approach prior to changes in organizational design contributes to the understanding and
perception of workers about the advantages and disadvantages of the rotation process, indicating
improvements that comply with legal requirements.2022-01-01T00:00:00ZSocial construction as a means of ergonomic intervention.Rocha, RaoniJackson Filho, José MarçalGarrigou, AlainNascimento, Adelaidehttp://www.repositorio.ufop.br/jspui/handle/123456789/168602023-07-03T19:28:28Z2022-01-01T00:00:00ZTítulo: Social construction as a means of ergonomic intervention.

Resumo: Although Ergonomic Workplace Analysis (EWA) practice is common in Brazil, some
critics have asserted that it is not sufficient to bring about an effective change of the workplace.
Although this criticism may be partly admissible in regard to Brazilian ergonomics, it cannot be
considered to apply to France, where Activity-Centered Ergonomics was born. At the same time,
it is important to not confuse EWA with the broader field of Activity-Centered Ergonomics. Against
this background, this article seeks to analyze the elements that characterize contemporary
ergonomics practices in Brazil so as to compare them to the modes of intervention developed in
France. We also seek to investigate models, concepts and methods so as to expand the
possibilities of ergonomic interventions in Brazil. To do so, we will start from a theoretical
examination of the development of EWA in Brazil from its origins in France, presenting an
intervention conducted at a French electricity company. Next, we will discuss the losses suffered
by EWA during the transfer of EWA methodology from France to Brazil, as well as the need to
cultivate social construction at all stages of these interventions. We conclude by showing the
importance of developing this debate in the field of ergonomics and the need to continue it.2022-01-01T00:00:00ZRobust stochastic frontier analysis applied to the Brazilian electricity distribution benchmarking method.Campos, Magno SilvérioCosta, Marcelo AzevedoGontijo, Tiago SilveiraLopes-Ahn, Ana Lúciahttp://www.repositorio.ufop.br/jspui/handle/123456789/168592023-07-03T19:24:47Z2022-01-01T00:00:00ZTítulo: Robust stochastic frontier analysis applied to the Brazilian electricity distribution benchmarking method.

Resumo: A Data Envelopment Analysis (DEA) method has been applied by the Brazilian regulator to set regulatory
operational costs for 61 electricity distribution utilities. Recent studies show evidence that the current method
still requires improvements. This study evaluates the use of Stochastic Frontier Analysis (SFA) as an alternative
method. Pros and cons are evaluated. Results show that the SFA is more flexible to deal with outliers. However,
the SFA has major convergence problems. Convergence issues can be overcome using Bayesian computations.
This study advocates the use of both DEA and SFA as the best alternatives, as indicated by European regulators.2022-01-01T00:00:00Z
