The construction manufacturing industry in North America has a disproportionately high number of lost-time injuries because the physical demand labor-intensive tasks it involves. It is thus essential to investigate demands body movement workplace proactively identify worker exposure ergonomic risk. This paper proposes methodology use three-dimensional (3D) skeletal modeling imitate human an actual plant for risk assessment workstation. inputs creation accurate and reliable 3D model are also...

Pose estimation of construction workers is critical to ensuring safe and protecting from ergonomic risks. Computer vision (CV)-based 3D pose for increasingly used in risk assessment (ERA) due its considerable practicability accuracy. Currently, the deficiencies (1) dedicated datasets activities (2) informative biomechanical models both Rapid Entire Body Analysis (REBA) Upper Limb (RULA) impede performance CV-based ERA sectors. Therefore, this study introduces a deep learning-based by...

Objective: To assess impact of personal protective equipment (PPE) on healthcare providers (HCPs) in caring for COVID-19 patients. Methods: A cross-sectional survey was conducted over 50 hospitals China. Descriptive analyses and Chi-square tests were performed the collected data. Results: All 104 frontline HCPs report negative impacts PPE their clinical performance, 97% them experienced discomfort injuries caused by wearing long hours. Frontline provided suggestions to alleviate enhance...

Workers in industrialized construction are often exposed to physical demands (e.g., repetitive motion and awkward body posture) associated with the risks of work-related musculoskeletal disorders, despite utilization automated equipment. To reduce exposure these risks, an investigation workstation design is needed. This paper proposes a virtual reality (VR)-based ergonomic assessment method that identifies risk ratings proactively initial phases design, thus reducing need for mock-ups...

Workers in offsite construction facilities are often exposed to repetitive motion and awkward body postures that associated with the risk of developing work-related musculoskeletal disorders despite use automated equipment on production lines. To reduce exposure these risks, an investigation physical demands workstations impose workers' bodies is needed. Since traditional methods used collect human motions have limitations, such as workplace interruptions biased results due subjective...

Real-time assessment of the ergonomic risks to which workers are exposed at a workstation and provision real-time corrective feedback intervention play an essential role in improving safety workplace through reduction long-term exposure ergonomically hazardous postures associated with physical fatigue work-related musculoskeletal disorders. This study proposes framework, virtual reality–based ergonomics training (VR-RET), that integrates reality (VR) inertia motion capture system rapidly...

Natural Gas Hydrate (NGH) and Hydrate-bearing Sediments (HBS) are emerging as an important potential energy resource. Radial Jet Drilling (RJD) technology, turning sharply in the casing drilling laterals by using water jet, is a valid approach to solve problems of high cost, low efficiency during exploitation NGHs. The performance jet remains unclear, traditional finite element methods cannot accurately depict ability due mesh distortion. This paper analyzes erosion process NGH HBS....

Collaboration in design decision-making is a critical factor enhancing the quality of built environments. However, several factors, such as lack clarity negotiation process, diverse disciplinary backgrounds stakeholders, and conformity bias, pose significant challenges, rendering collaboration environment time-consuming. To overcome these challenges improve efficiency collaborative design, novel solution that introduces consensus model enhanced by virtual reality (VR) proposed this paper....

Purpose In response to increasing demand for a fully customized and individualized home environment, mass customization (MC) has been suggested as an effective strategy fulfill the customer’s needs while keeping production cost-effectiveness. However, in current practice, implementation of MC industrialized housing industry not achieved ideal level. Little effort was devoted customer value generation achieving lean multi-disciplinary environment. this concern, highly efficient flexible...

Worker safety and productivity the factors that affect them, such as ergonomics, are essential aspects of construction projects. The application ergonomics identification connections between workers assigned tasks have led to a decrease in worker injuries discomfort, beneficial effects on productivity, reduction project costs. Nevertheless, area often subjected awkward body postures repetitive motions cause musculoskeletal disorders, turn leading delays production. As systematic widely used...

Workers in the construction manufacturing industry are often exposed to three primary causes of work-related musculoskeletal disorders (WMSDs): awkward body posture, forceful exertion, and repetitive motion. The investigation physical demands movement is thus needed during design machines workstations minimize WMSDs. In context industry, this paper proposes implementation immersive virtual reality ergonomically test new workstations/machines with a particular focus on assessment human...

Working on a moving platform can significantly impede human performance. Previous studies vehicles have often focused the overall impact general task performance, whereas our study’s emphasis is precise hand movements, exploring interaction between body motion and escalation of difficulty. We recruited 28 participants to engage in reciprocal aiming tasks, following Paul Fitts’s setting, under both in-motion stationary conditions. The index difficulty (ID) was manipulated by varying width...

Abstract Customer relationship management (CRM) and enterprise resource planning (ERP) have been extensively discussed in the research literature respectively. However, existing studies do not reach a complete agreement on CRM/ERP integration method, especially for small- medium-sized enterprises (SMEs). Generally, this work proposed novel method approach via associative feature technology. A new type, Real-time Data Link Board (RDLB), is developed detailed as generic information carrier...
