This study investigates the effects of different floor inclinations on torque production, ground reaction forces, and postural adjustments during a handwheel maneuvering task. Participants performed maximal isometric torque exertion by operating a handwheel at floor inclinations ranging from 30° backward to 30° forward around the transverse axis. Handwheel torque, Ground Reaction Forces (GRFs) under both feet, and kinematics data for postural adjustments were recorded. The results revealed significant variations in handwheel torque production, GRFs distribution, and postural alignment as a function of inclination angle. Specifically, there was a significant reduction in handwheel torque production of up to 19 % (p < 0.01) at extreme forward inclination and 16 % (p < 0.05) at extreme backward inclination compared to the horizontal condition. GRFs analysis showed adjustments in forces distribution between the feet. Kinematics analyses demonstrated significant postural adjustments affecting body alignment and force generation capacity. This study provides critical data for design engineers, highlighting the challenges of handwheel torque production and the importance of considering lower limb contributions and postural adaptations at steep inclinations. These results emphasize the need to account for floor inclination in equipment design and operator training can enhance safety and performance.</div></div>","PeriodicalId":50317,"journal":{"name":"International Journal of Industrial Ergonomics","volume":"107 ","pages":"Article 103740"},"PeriodicalIF":2.5,"publicationDate":"2025-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143825487","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}

From a business perspective, this also increases the likelihood of product returns. While various methods have been proposed to classify breast shapes and enhance bra design, the lack of accessible measurement tools and expertise often makes it difficult for young women to select appropriate bras. This study addresses this issue by introducing a Long Short-Term Memory (LSTM)-based recommendation system that helps young women easily and accurately choose well-fitting bras. To precisely identify the shapes of young women's breasts, this study collected human body data from 150 individuals using a 3D body scanner and employing ergonomics expertise and statistical analysis methods such as Principal Component Analysis (PCA) to classify 7 key indices such as bust circumference, underbust circumference, and lower mammary cup arc length as breast shape indices. The k-means clustering method subdivided breast shapes into six categories. Next, based on the classification result, an LSTM based discrimination model was developed to identify the breast morphology, achieving a breast identification accuracy of 85.71 %, surpassing both the Back Propagation (BP) neural network and Convolutional Neural Network (CNN) in terms of operational efficiency, fitting accuracy, and overall performance. Finally, users only need to input the breasts measurements to receive recommended bra parameters and corresponding style chart. This study not only enhances comfort and health by facilitating optimal bra selection but also minimizes return rates and improves the shopping experience, crucial for the sustainable development of the apparel industry.</div></div>","PeriodicalId":50317,"journal":{"name":"International Journal of Industrial Ergonomics","volume":"107 ","pages":"Article 103736"},"PeriodicalIF":2.5,"publicationDate":"2025-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143816114","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}

Spatial accessibility evaluation, as a critical indicator of worker safety and product design optimization, is an essential part of equipment product design. This study proposes a comprehensive evaluation method based on digital human models (DHMs) and virtual reality systems (VRS) for the quantitative analysis of operational accessibility in CS. The method integrates DHMs and ergonomics data to analyze human dynamics, path accessibility, operational accessibility, and visibility. It defines the spatial restriction ratio (SRR) and the operational freedom ratio (OFR), and combines directional weight coefficients for specific operation types with REBA posture ratings to construct a multi-dimensional quantitative evaluation system. The experiment was based on 6 confined units and 11 operations of an equipment, recruiting 10 subjects to simulate real operations through VRS to validate the effectiveness of the method. The results of the tests demonstrate that the method can effectively evaluate the operation accessibility in CS, optimize the product layout, reduce the risk of musculoskeletal injuries for workers, and provide theoretical support for the iterative design of industrial equipment. It promotes the transition of operational accessibility evaluation in CS from experience-driven to data-driven precision upgrades, offering new perspectives and methodological support for the spatial layout optimization and scientifically reasonable operation planning of complex industrial products.</div></div>","PeriodicalId":50317,"journal":{"name":"International Journal of Industrial Ergonomics","volume":"107 ","pages":"Article 103719"},"PeriodicalIF":2.5,"publicationDate":"2025-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143808082","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}

Physical stress imposed as physical exertion is a major workplace stress category that impacts construction workers' safety behavior. While previous studies have demonstrated the effect of physical exertion on workers' hazard recognition and safety performance, research gaps persist regarding the direct impact of physical exertion on workers' physiological responses and near-miss recognition performance. This study investigates workers' ability to recognize near-miss incidents using an eye-tracking experiment conducted in controlled non-stress and physical stress (overexertion) conditions. Thirty-five participants were exposed to near-miss scenarios from construction sites. Physiological and eye-tracking matrices measured their bio signals and safety behavior during the experiment. The findings from this study reveal that physical overexertion triggered by manual material handling activity can adversely affect worker safety behavior and cognitive ability toward near-miss recognition. Visual attention toward near-miss scenarios was reduced by 39.43 % post-exposure to physical exertion. Additionally, physiological data collected using wearable sensors shows a significant statistical association with near-miss recognition of participants. Individuals with low neuroticism and extraversion showed the highest reduction in recognition performance post-exposure to physical exertion. The study confirms the significant impact of fatigue on reducing workers' efficiency in identifying near-misses, suggesting avenues for developing overexertion relief assessment systems using wearable sensors. Additionally, personality-based safety worker allocation models could aid in recruiting and training workers with lower recognition abilities.</div></div>","PeriodicalId":50317,"journal":{"name":"International Journal of Industrial Ergonomics","volume":"107 ","pages":"Article 103737"},"PeriodicalIF":2.5,"publicationDate":"2025-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143768688","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}
