This research project was designed to investigate cultural and cognitive issues related to the work of nuclear power plant operators during their time on the job in the control room and during simulator training (emergency situations), in order to show how these issues impact on plant safety. The modeling of the operators work deals with the use of(More)
A fundamental challenge in improving the safety of complex systems is to understand how accidents emerge in normal working situations, with equipment functioning normally in normally structured organizations. We present a field study of the en route mid-air collision between a commercial carrier and an executive jet, in the clear afternoon Amazon sky in(More)
This paper presents a protocol for work distress assessment. Work distress is defined as a merge between nonergonomic related aspects, in tasks or environment, and adversely conditions perceived for a worker, in a certain work situation. This frame requires an approach that can treat individuals and organizational factors in the same way, at the same time.(More)
Radiopharmaceuticals are radiation-emitting substances used in medicine for radiotherapy and imaging diagnosis. A Research Institute, located in Rio de Janeiro, produces three radiopharmaceuticals: the sodium iodate is used in the diagnosis of thyroid dysfunctions, the meta-iodo-benzylguanidine is used in the diagnosis of cardiac diseases, and the(More)
This article discusses the development of a computerized support to demands for treatment of a wide spectrum and diverse nature. Developed under SPM platform (Situação, Problema e Melhoria), the practitioner seeks to provide an ergonomic aid from the identification and characterization of the processes of analysis demands. The interest of a technological(More)
This paper presents a study about fatigue recovery time assessment processes in work activities. It came about due to a demand presented by an automotive industry giant, in need of updating existing cycle time sheets and TAKT time parameters. The company decided to hire an Ergonomics Laboratory with ties to a major Brazilian University in order to evaluate(More)
This paper aims at the application of an ergonomic maturity model (EMM), in order to assess the ergonomic sustainability outreach of ergonomic actions. This proposition was motivated by the widespread sensation that the development of the discipline, its educational devices and related practices depends on the attitude of ergonomics practitioners rather(More)
In this paper, we analyzed two laboratories of liquid chromatography (LC), separation technique of mixtures and identification of its components, in order to identify projectual gaps relating to the environment and the working station. The methodology used was the ergonomic analysis with interactional and participatory techniques applied during the activity(More)
BACKGROUND This literature review covers original journal papers published between 2011 and 2015. These papers review the current status of research on the application of human factors and ergonomics in risk assessment systems' design to cope with the complexity, singularity, and danger in patient triage in primary health care. OBJECTIVE This paper(More)
In this paper, we study the importance of a consistent description of real work in patient risk assessment in the primary healthcare domain. Through a case study in the context of primary health care, we address the research problem of finding ways to build consistent real work descriptions of the patient risk assessment system in the primary healthcare(More)
