This article corresponds to a case study with 6 young male military who were tested for three types of exertion: marching without load, marching with load, and running at two different environmental conditions: thermoneutral (± 22°C and ± 40% rh) and thermal stress (± 40°C and ± 30% rh), with two adaptation levelsunacclimated and acclimated to the thermal stress condition. Core temperature, heart rate, VO2,body mass loss, and lactate were measured; the Borg Rating of Perceived Exertion (RPE) was also used. The thermal stress situation decreased the overall physiological performance and increased the rate of perceived exertion. After acclimation all participants improved their overall performance.

In the fresh food industry the working activities are conducted in environmental temperatures from 0°C to 10°C, while in the frozen food industry usually are at temperatures below 20°C which influences the variations in core and skin body temperatures and affects the working performance, health and safety of the employees. The aim of this work is to contribute with a study on the influence of cold thermal environment on core and skin body temperatures in packing workers from the frozen food industry. By using the core body pill sensor and 8 skin temperature sensors a study was conducted on 4 workers during 11 days. The lowest recorded temperature was for hand 14.09°C, mean skin temperature had variations of 1.10 to 3.20°C along the working period and the mean body temperature on two occasions decreased below 35°C. The core temperature was found to increase. The mean body temperature showed small changes along the time. (c) 2017 Taylor & Francis Group, London.

Work-related musculoskeletal disorders (WMSDs) are a leading work-related health issue. Work-related disability and illness are common in a wide range of activities. The association of the musculoskeletal disorders and work possibly have a temporal cause-effect relation. This study investigated the prevalence and incidence of upper-limb work-related musculoskeletal disorders in a factory dairy products. The study was carried out between 2010 and 2014 among the 166 workers belonging to the cheese sector. Two evaluations were done, one in 2011 and another in 2014 and the study is limited to a total of 134 workers who were evaluated in both. It was found a total symptoms prevalence of upper limb musculoskeletal disorders of 38.1% and 31,1% in the first and second evaluation, respectively. Respect to the incidence of musculoskeletal disorders from the first to the second evaluation, the value found was 8.2% These values justifies the need to undertake preventive measures, reducing the injuries and consequently costs associated with these disorders.

Workplace noise is a global scale problem affecting workers of almost all activities. Driving urban buses is one of those activities. In order to investigate the relationship between noise and city driving variables, in this work were analysed twelve drivers, four models of buses, four routes with different characteristics and executed four trips in each route. The measurements were done in continuously along all driving time. The equivalent continuous sound level (LAeq) was obtained from observation periods with a mean time around 150 min. The data were submitted to a statistical treatment with principal components analysis, Kolmogorov-Smirnov and variance analysis. Based on the records resulting from monitoring performed, it was concluded that the LAeq values are dependent on the type of bus and on the route, with no clear evidence of the influence of the human factor (driver) on the observed noise levels.

The problem of noise in the public transportation bus and its effect to the driver must be considered systematically and examined in detail. The main aim of this short review is to approach the problem as detailed as possible, compare results and determine the effect(s) of the noise to the driver. For the purpose of this work the PRISMA Statement Methodology was applied. Were found 1119 articles and 14 included in this short review. Most of the results have been obtained using ANOVA Analysis and measurements that comply with standards (ISO 9612:2009, ISO 5128:1980, ISO 1999:1990). This paper illustrates the noise level variations depending on the city bus model, its age, engine position, and other factors that disturb the comfort of working space. Regarding the analysed results from the different papers, the noise depends mostly on the engine position in the bus. (c) 2017 Taylor & Francis Group, London.
