One of the sciences which considers to human health, human performance and body activities is Ergonomics. Ergonomics is one of the modern sciences, drawing as much from the field as from the laboratory, and including elements of art and craft as well. Before designing the workplace it is necessary to determine its requirements, i.e., which it is in...

... the monitor. Improved height adjustability with the chair may also allow the user to find a comfortable viewing angle without changing monitor height. Fig. 1 displays the a priori theory of change guiding the research ( Amick et al., 2003). The office ergonomics training was expected to increase knowledge and with the new highly adjustable chair (Fig. 2) postural risks are reduced and healthy computing behavior encouraged. ( Amick et al., 2012). ...

Office activities were closely tied to document handling and computer interaction. Based on initial identification with the Nordic Body Map, MSDs (Musculoskeletal Disorders) complaints were identified in the shoulders, wrists, waist, buttocks, and back. This study aimed to offer recommendations for enhancing office workstations to minimize the risk of MSDs. The methods used are ROSA to identify employee work postures, product design to provide proposed work facilities, 5S for document organization, and a Radar Chart for evaluation. Initial identification shows the problems that exist in work facilities, workspace layout, and work environment factors. The initial identification of the workspace with Radar Chart also showed a poor score on 5 aspects of Seiri, Seiton, Seiso, Seiketsu, and Shitsuke with an average of 41.75. The proposed intervention is the improvement of ergonomic tables and chairs, structuring documents by applying 5S aspects, and improving the layout of the workspace. The proposed improvements were then evaluated again using the Office 5S Audit Checklist and Radar Chart so that after the ergonomics intervention, the Radar Chart value became 90.75 (excellent) and the 5S aspects (Seiri, Seiton, Seiso, Seiketsu, and Shitsuke) increased. The results of this improvement can be expected to overcome the risk of MSDS problems in the lower neck, buttocks, back, and waist and the resulting ergonomic, organized, and efficient workstations.
Labor is one of the most critical resources in the construction industry due to its impact on the productivity, safety, quality, and cost of a construction project. Ergonomic assessment, as a tool and method for analyzing human activities and their interactions with the surrounding environment, is thus crucial for designing operations and workplaces that achieve both high productivity and safety. In construction, however, the constantly changing work environments and laborious tasks cause traditional approaches to ergonomic analysis, such as manual observations and measurements, to require substantial time and effort to yield reliable results. Therefore, to simplify and automate the assessment processes, this study explores the adaptation and integration of various existing methods for data collection, analysis, and output representation potentially available for comprehensive ergonomic analysis. The proposed framework integrates sensing for data collection, action recognition and simulation modeling for productivity and ergonomic analysis, and point cloud model generation and human motion animation for output visualization. The proposed framework is demonstrated through a case study using data from an off-site construction job site. The results indicate that integrating the various techniques can facilitate the assessment of manual operations and thereby enhance the implementation of ergonomic practices during a construction project by reducing the time, effort, and complexity required to apply the techniques.
