During last years, the car’s manufacturing process has deeply changed because of several factors affected the automotive global scenario. As a consequence, design methodologies of the plant’s workcells have changed. In particular, ergonomics for manufacturing system has become a key factor to improve product’s quality, safety and work organization. In this paper, the authors show the approach u...

This paper analyses two proposals that seek to contribute to sustainability from an HFE perspective: ergoecology and green ergonomics. It presents both approaches, their principles, purposes, and fields of application, thereafter dealing with their context of emergence, and overlaps in purpose, principles, and shared values. The principles of ergoecology are given as a framework for developing ...

Progress toward improving patient safety has been slow despite engagement of the health care community in improvement efforts. A potential reason for this sluggish pace is the inadequate integration of human factors and ergonomics principles and methods in these efforts. Patient safety problems are complex and rarely caused by one factor or component of a work system. Thus, health care would be...

It can be observed an increased concern about the school classrooms, in particular about the study and design of school furniture fitting the students’ needs and anthropometrics characteristics. The main aim of this study was to perform an anthropometric survey, considering the main anthropometric dimensions and, in accordance, to define the dimensions and characteristics of school furniture fo...

In this paper, we propose spatio-temporal silhouette representations, called silhouette energy image (SEI) and silhouette history image (SHI) to characterize motion and shape properties for recognition of human movements such as human actions, activities in daily life. The SEI and SHI are constructed by using the silhouette image sequence of an action. The span or difference of the end time and...

For many industrial tasks (push, pull, lift, carry, etc.), restrictions on grip locations and visibility constrain the hand and head positions and help to define feasible postures. In contrast, foot locations are often minimally constrained and an ergonomics analyst can choose several different stances in selecting a posture to analyze. Also, because stance can be a critical determinant of a bi...

Ergonomics is defined by the International Ergonomics Association ergonomics as the scientific discipline concerned with the understanding of interactions among humans and other elements of a system, and the profession that applies theory, principles, data and methods to design in order to optimize human well-being and overall system performance. Ergonomics is employed to fulfill the two goals ...

One of the production processes for making weaving from doyo leaf fiber is process softening dry before it spun into yarn. This done so that dried fibers become more flexible and elastic they can be easily aspect machine design reviewing ergonomic factors machines used by workers are safer comfortable. study aims to a softener in terms ergonomics machine's products.
