Investigating interactions among vital variables affecting situation awareness based on Fuzzy DEMATEL method
This study aims to identify interactions among the most important individual, situational, and organizational variables affecting situation awareness in industrial workplaces. Using Fuzzy Delphi and Fuzzy DEMATEL methods, this study was conducted based on the data collected from experts’ judgments. The results show that organizational variables and some individual variables are the critical factors affecting situation awareness, and their effect is directly or indirectly created by situational and individual variables. The results of the study can be used to design proper guidelines for industry managers and employers to...

Hairdressers’ shoulder load when blow-drying – Studying the effect of a new blow dryer design on arm inclination angle and muscle pain
Publication date: November 2019Source: International Journal of Industrial Ergonomics, Volume 74Author(s): Morten Wærsted, Henrik Enquist, Kaj Bo VeierstedAbstractDuring nine months, nineteen hairdressers every second/third month switched the use between a blow dryer with traditional design and one with a new design. The new blow dryer had the possibility to change between two opposite directed air flows. Every second/third month arm inclination angle and upper trapezius muscle activity were measured a whole workday, and during blow-drying in the laboratory. Pronounced upper arm elevation was reduced with the new blow dry...

Lumbar posture and individual flexibility influence back muscle flexion-relaxation phenomenon while sitting
This study, therefore, recruited 18 male students and assigned to low- and high-flexibility groups (9 in each). Activation of thoracic and lumbar erector spinae (ES) and lumbosacral angles were examined while participants sat in two postures (lordosis and kyphosis) and flexed their trunks at 15°, 30°, 45°, 60°, and maximum flexion. Results showed that kyphotic lumbar posture caused relatively low and unchangeable thoracic and lumbar ES activations, whereas lordotic lumbar posture engendered more contractive and varying thoracic and lumbar ES activations. Flexible participants exhibited higher thoracic ES activation tha...

The investigation of work-related musculoskeletal disorders among female workers in a hazelnut factory: Prevalence, working posture, work-related and psychosocial factors
ConclusionsWMSDs are common among female workers in a hazelnut factory. Reorganizing of working posture, work-related factors, and stress at work may be beneficial to decrease the prevalence of WMSDs and pain severity.Relevance to Industry; The female workers in the hazelnut factory are vulnerable to the work-related musculoskeletal disorders, particularly in the spinal region. The employers should endeavor to improve the health of the workers by the adjustment of the working posture and environmental factors. (Source: International Journal of Industrial Ergonomics)

Anthropometric characterisation of palm and finger shapes to complement current glove-sizing systems
Publication date: November 2019Source: International Journal of Industrial Ergonomics, Volume 74Author(s): Margarita Vergara, Maria-Jesus Agost, Vicente BayarriAbstractHand length and width have traditionally been considered key metrics for glove-sizing systems. Morphological differences in palm and finger shapes should also be considered for more accurate glove fitting.In this paper, finger and palm lengths of the five hand digits of 139 subjects from a Mediterranean population were measured. Hierarchical clusters and analysis of variance were applied to identify morphological differences. Three palm shapes and three fing...

Underwater space suit performance assessments part 2: Reach envelopes as a comparative performance metric
This study assessed the reach envelopes as a quantitative metric to compare the mobility of different spacesuit types, namely the existing extravehicular mobility unit (EMU) and the newly developed prototype Z2. With Z2, two different configurations were considered: 1) Z2 paired with the EMU lower torso assembly (Z2-ELTA) and 2) Z2 with the mobile lower torso assembly (Z2-ZLTA). Five subjects performed reach motions in the underwater microgravity analog, including isolated hand and arm reaches (IHAR: arm sweeps at the shoulder) and whole-body reaches (WBR: reaches at extreme whole-body stretching/bending poses). The analys...

The use of pressure mapping to assess the comfort of agricultural machinery seats
Publication date: Available online 14 August 2019Source: International Journal of Industrial ErgonomicsAuthor(s): Elio Romano, Marco Pirozzi, Marco Ferri, Aldo Calcante, Roberto Oberti, Ermanno Vitale, Venerando RapisardaAbstractInterface pressure measurement gives an objective value to human comfort. Prolonged sitting is known to contribute to musculoskeletal disorders. Driving a tractor involves several actions such as steering, operating levers, buttons, brake and clutch pedals, and looking behind to observe and maneuver the machine. These operations affect sitting posture and create a pattern of loading on the structur...

The occupational illness of slum dwellers across industries: A case study in West Bengal
Discussions (FGDs). The determinants of the nature of occupational illness are analyzed with an ordered Logit model. The chronic illness like respiratory diseases are prevalent among the workers of jute textile industries, and musculoskeletal disorders are found mostly among the workers of small garment and consumable items industries. The prevalence of occupational injuries is common among the workers of the civil-mechanical and chemical industries. The difference in the Out-of-Pocket Health Expenditure (OOPE) between doctor's consultation and consumption of Over the Counter (OTC) drugs of the industrial workers might pre...

Ergonomics demands associated with combinations of manual and powered emergency medical service cots and ambulance loading systems: A work simulation study
Publication date: September 2019Source: International Journal of Industrial Ergonomics, Volume 73Author(s): Jim R. Potvin, Aidan W. PotvinAbstractDigital human models were used to perform a virtual ergonomics assessment of manual and powered emergency medical services cots combined with both manual and powered ambulance loading systems. Simulations were run with all combinations of emergency medical technicians (EMTs), at 50 kg (female), 72 kg (female) and 125 kg (male) with cots containing no patient and patients of 125 kg and 159 kg. There was a substantial decrease in low back and upper extremity demands with ...

Traditional and 3D scan extracted measurements of the heads and faces of Dutch children
Publication date: September 2019Source: International Journal of Industrial Ergonomics, Volume 73Author(s): Lyè Goto, Wonsup Lee, Johan F.M. Molenbroek, Annoesjka J. Cabo, Richard H.M. GoossensAbstract3D anthropometry has created a significant opportunity for designers to improve fit by offering detailed information regarding the shape of the human body. Various researchers have shown the benefit of using 3D anthropometric data in the development or evaluation of head related products for adults. However, detailed 3D anthropometric data of children heads and faces is still lacking. This paper presents up to date descripti...

The effects of load weight and load starting height on variability of lifting kinematics and kinetics
Publication date: September 2019Source: International Journal of Industrial Ergonomics, Volume 73Author(s): Hamid Norasi, Jordyn Koenig, Gary A. MirkaAbstractTrunk kinematic variables have been used to understand the risk of low back injuries in the workplace. Variability in the trunk kinematics as an individual performs a repetitive lifting task is an underexplored area of research. In the current study, it was hypothesized that workplace variables (starting height of lift and load weight) would have an impact on the variance in the kinematic and kinetic variables. Twenty participants performed 60 repetitions of an asymme...

Experimental analysis of user forces by test bench and manual hammer drill experiments with regard to vibrations and productivity
Publication date: July 2019Source: International Journal of Industrial Ergonomics, Volume 72Author(s): Michael Uhl, Tim Bruchmüller, Sven MatthiesenAbstractThe user's forces have great influences on the load and on the drilling process of hammer drills. Hence, these influences must be known in product development for reproducible testing on test benches. Furthermore, manufacturers focus on developing hammer drills, which improve productivity and force-efficiency during application. Therefore, the aim of this study is to investigate the influences of the forces exerted by the user on a hammer drill when drilling in concret...
