The aim of the paper is to describe a possible direction of development and theoretical model for ergonomic research in the Virtual Reality (VR) field dedicated to psychotherapy applications. Through considerations on the strong points and limitations encountered during two different projects dedicated to the creation of virtual reality environments (VRE) for use in psychotherapy, it comments o...

The effectiveness of ergonomics application is achieved in the course of this research by reviewing ergonomics literature, Internet searches and case studies of a number of work related musculoskeletal disorders (WMSD's) and other ergonomic related workplace incidence rate. The results of ergonomic intervention control measures such as engineering controls, administrative controls and personnel...

The growing concern for the welfare of workers in the work environment, the importance of widespread use of ergonomics in the different sectors of industry. Yet most corporate practices that work with rudimentary or great need for human handling of materials is not fully in line with the ergonomic aspects. Given this, this article aims to identify ergonomic hazards in mining to later propose im...

The objective of this research is the development of an effective design of an assembly line for heaters production by taking into consideration work measurement, line balancing and ergonomic problems. As the assembly line is still not in existence and no data are available, it is quite difficult to evaluate, for each assembly line workstation, the work assignment, the assembly times as well as...

This paper evaluates the effect of ergonomic factors on task performance and trainee posture during laparoscopic surgery training. Twenty subjects without laparoscopic experience were allotted into 2 groups. Group 1 was trained under the optimal ergonomic simulation setting according to current ergonomic guidelines (Condition A). Group 2 was trained under non-optimal ergonomic simulation settin...

Practitioners of endoscopy often experience musculoskeletal pain and injury (most often in the back, neck, shoulders, hands, wrists, and thumbs) that are associated with the minute and repetitive strain that is placed on these areas during endoscopic procedures. This review of the current documentation of endoscopy-related pain and injuries among practitioners finds that such problems are wides...

Ergonomic design is the adaptation of working conditions to human limitations and skills in the physical design phase of a new installation, a new working system, or new products or tools. Based on this concept, the purpose of this work was to analyze the implementation of ergonomic design at the new industrial units of an oil refinery, using the method of Ergonomic Workplace Assessment. This s...

This paper makes suggestions for the realization of an ergonomic intervention, guided by the method of Moraes and Mont'Alvão (2009), in the system of street vending of porridge, to improve the working conditions of this sales segment. Specifics are given about this practice and its problems, from ergonomic analysis comes to suggestions for improvements to be applied to a new system.

In this paper, we present an extension to the TSALB problem (Time and Space constrained Assembly Line Balancing) with ergonomic risk restrictions. This ergonomic risk is defined from the task durations and their categories regarding to the risk factor for the workers. A study is presented through a case linked to an engine assembly line in the Automobile industry, considering variable demand.
