While a large metabolic rate reduction (>15%) is required to significantly slow the core temperature increase, even a minor metabolic rate reduction (5%) could provide a substantial reduction (20%) in the sweat rate (i.e. could reduce dehydration).

Forty-four participants were equally divided into AR and ordinary training groups with the equivalent instructional materials, which included text information and 3D models. Results show that although AR did not significantly affect the overall workload and system usability assessment (SUS) recorded, several experimental values increased significantly compared with the ordinary training method, including task completion time, time required to interpret text-based information, amount of attention switching, and training effectiveness. Consequently, the use of AR did not result in a completion time and workload reduction; however, we found that training with the AR system was more effective than ordinary training in increasing the knowledge retention of participants without increasing their overall workload, especially for the month-term memory.

Vibration emission in the drilling process can cause various occupational diseases. Workers influence this process mainly by varying the feed force. A feed force variation in hammer drilling causes a machine-specific motor speed reduction. As it is impossible to distinguish the effect of feed force on vibration and productivity from machine-specific motor speed reduction effects, the findings of various studies on hammer drilling vary considerably. The goal of this study therefore is to identify the feed force effect on vibration and productivity, thus excluding machine-specific effects due to a motor speed reduction. We modified a hammer drill to keep motor speeds constant over a wide feed force range and conducted a drilling study using an automated drilling test rig. The drilling productivity increased with higher feed force, whereas machine-specific motor speed reduction led to a decrease. Evaluated with Cohen's f, both factors had a large effect (feed force: f = 0.62, motor speed: f = 0.42). An increasing feed force led to a higher vibration emission with a large effect (f = 1.03). Motor speed reduction reduced vibration with a small effect (f = 0.21). Further hammer drill studies are needed to specify machine-specific motor speed reductions for comparing the results of different studies. The isolated effects could be used by manufacturers to implement control strategies for automatic optimizations. Based on the feed force, motor speed could be varied to optimize vibration or productivity.</p></div>","PeriodicalId":50317,"journal":{"name":"International Journal of Industrial Ergonomics","volume":null,"pages":null},"PeriodicalIF":3.1,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138136105","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
