“…Similarly, one discomfort indicator parameter (LPD rating) and four anthropometric parameters of the subjects (gender, hand length, hand width, and grip strength) were also related to the evaluation of comfort of sport tool grips, and this result was consistent with [13][14][30][31]33 .…”

“…The questionnaire takes into account the functionality, physical irritation, tactile characteristics, and quality and appearance of the hand tools [8][9][10] . Discomfort perception has also been found to be a potential factor influencing the comfort experience, generally using the validated Local perceived discomfort of arm and hand (LPD) map [11][12][13][14] to be assessed.…”

In order to provide a set of quantitative evaluation of the comfort of hand-held sports products, this study preliminarily constructed the comfort evaluation index system of hand-held sports products from the perspectives of performance, tactile characteristics, quality and appearance, physical stimulation, discomfort, morphological characteristics, user demographic characteristics and hand characteristics. Secondly, 165 groups of data were collected through the experiment, and factor analysis was used to reduce the dimension of the original index. Then neural network was used to establish the mapping relationship between the evaluation index and the comfort evaluation, and the evaluation model of the comfort of hand-held sports products was obtained. The results show that the relative error between the predicted value and the actual value of the network model is basically less than 5% in the practical application of the evaluation method taking the badminton racket as an example, which reflects that the comfort evaluation method can effectively reduce the correlation between the original indexes, achieve the accurate evaluation of the comfort of products, and verify the effectiveness and feasibility of the evaluation method. The combination of neural network and factor analysis can quantitatively analyze and evaluate the comfort of hand-held sports products and provide reliable suggestions for manufacturers to design and produce more comfortable products in the form of data.

“…Environmental legislation relevant to unsanitary work conditions was therefore used as a guideline. Several articles highlighted the influence of environmental characteristics on human performance in activities within systems that are deemed complex due to their functions and physical structure [29]. Examples of research in different environmental contexts include noise [47,48,49]; heat [50]; vibration [51]; musculoskeletal demands [52] and task complexity [53].…”

“…Through systematic observation of certain operator actions, it was possible to understand how, why, for what reason, and under what conditions the work activities were carried out [29]. In this stage, monitoring of the working day, to ascertain the percentages of the time taken for each activity to be carried out, was documented in the timesheet.…”

Practical Application of Ergonomic Methodology Identifying Critical Activities in a Metallurgical Electrolysis Unit

This work presents a multidisciplinary methodology for the identification of critical activities in an industrial process utilizing task time quantification techniques present in ergonomic analysis and involving the participation of socio-technical users. It involved an activity analysis that focused on the individual workers' functions and behavior when carrying out their tasks in a metallurgy electrolysis unit. The choice of critical activities was based on levels of exposure to occupational, environmental and operational health risks present during the working period. The methodology identified critical activities that put both the health and safety of the workers at risk. The operators' participatory and constructive approach reduced analytical subjectivity, providing consensual conclusions. Questionnaires were used to produce a pain map that sought to analyze the stress placed on the workers' musculoskeletal system as a consequence of performing their activities. The quantification of time in the operator's workday identified the criticality of exposure to occupational health risks associated with the operational procedure. A process validation was reached, which integrated a postural and kinesiological analysis with the operators' perceptions according to their responses to questionnaires. As a result of the analysis undertaken in this work it was also possible to identify an increase in deformities present in copper cathodes and a corresponding increase in on-time activities to remove them that had led to production losses as well as worker discomfort. The methodology, which included the operators' opinions and perceptions, concluded with a process validation. This work describes a set of proposed metrics based on ergonomic principles.

“…Van der Molen et al [ 2 ] tried to determine the differences in the number of paving stones laid (productivity), task demands, energetic workload, body region discomfort and preference when laying paving stones with or without use of a paver’s trolley. It was observed that the use of a paver’s trolley had no effect on productivity, body region discomfort compared to working without a paver’s trolley.…”

BackgroundImproper workstation, work procedures and tools are found to be the risk factors for the development of musculoskeletal disorders among the informal sector workers of the developing countries. Low cost ergonomic interventions can effectively improve such adverse conditions.Case presentationIn the present article some studies related to design interventions in different informal and agricultural sectors were discussed and their efficacies were analyzed. It was observed that with the help of appropriate interventions musculoskeletal disorders were reduced, adverse physiological conditions were improved when awkward postures were corrected and ultimately the organisational productivity was increased.ConclusionProper implementation of ergonomic interventions can ultimately improve the economy of the nation.
