Janitors consider the job labor intensive, and that workload is increasing in recent years. The most impacted body parts are hand/wrist, shoulder, and back in this population. This paper reports a compendium of physical ergonomics exposure assessment using three observational methods. The composite Strain Index (COSI) for hand/wrist, Manual Task Risk Assessment (ManTRA) for shoulder, and Recommended Cumulative Recovery Allowance (RCRA) for shoulder and back, were chosen for their capability to capture the complex and dynamic nature of all tasks performed in a janitorial job. Forty-six unique cleaning task-location-tool combinations received assessments, and the risk scores from the three methods are compiled into a compendium. This information can help practitioners to estimate the risk for a job, or designers to plan jobs for a team of janitors so the risks can be mitigated with careful task assignments.</p></div>","PeriodicalId":50317,"journal":{"name":"International Journal of Industrial Ergonomics","volume":null,"pages":null},"PeriodicalIF":3.1,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139433995","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}

However, the number of users complaining of VR motion sickness (MS) has been rapidly increasing. In this study, VR MS was investigated using subjective questionnaires: simulator sickness questionnaire (SSQ), virtual reality sickness questionnaire (VRSQ), and fast motion sickness scale (FMS) and objective physiological methods: electrodermal activity (EDA). To track VR MS based on symptoms, a model was constructed by applying a polynomial regression<span> method. In addition, this study attempted to determine whether there are differences in MS according to the degree of immersion in a VR environment. Twenty participants (10 males and 10 females) were exposed to a dynamic VR environment through a simple operation method using a head-mounted display (HMD). The coefficients of determination of the objective measurement components were high before and after the rest. In particular, both the SSQ and VRSQ were highest for disorientation, that is, dizziness disorder and difficulty concentrating. This suggests that the timing of the EDA signal data extraction with respect to the rest may be critical. In addition, subjects placed in an immersive VR environment performed the experiment in an unstable and dynamic posture; accordingly, the VR MS score was higher for subjects who participated in the experiment in a more dynamic position. Therefore, we confirmed the possibility of a significant association between VR sickness and postural stability. This study demonstrates the possibility of tracking MS in a dynamic VR environment according to intervals and symptoms using EDA signals, and the stability of posture should be considered in immersed VR environments.</span></p><p>Relevance to industry: The findings here provide insights into the model of tracking motion sickness using the EDA signal to prevent or reduce VR motion sickness.

Research tested a structural equation model (SEM) that describes hypothetical relationships between risk factors and WMSDs. Questionnaires were used to collect data on sociodemographic, occupational, biomechanical, and psychosocial factors<span>, and pain symptoms about 420 workers. The results showed that different factors directly affect the thigh, leg, and foot. Maintaining the lower limbs in uncomfortable positions increases the chances of developing WMSDs in the thigh (β = 0.219; p-value &lt;0.001), leg (β = 0.223; p-value &lt;0.001), and foot (β = 0.158; p-value &lt;0.01). Most psychosocial factors attenuate psychosocial stress, which in turn directly alleviates WMSD symptoms in the thigh (β = −0.502; p-value &lt;0.001), leg (β = −0.315; p-value &lt;0.01), and foot (β = −0.246; p-value &lt;0.01). Factors were also found to uniquely affect aspects such as “another job” (β = −0.246; p-value &lt;0.01) in the leg and effort (β = 0.146; p-value &lt;0.05) in the foot. It was concluded that multiple factors influence the development of WMSDs in the lower limbs. These findings contribute to the existing knowledge on the causes of WMSDs and can help improve working conditions for the population under study. Therefore, managers and health, ergonomics, and occupational safety professionals can use the findings to develop more precise strategies to reduce the impacts of WMSDs on workers.</span></span></p></div>","PeriodicalId":50317,"journal":{"name":"International Journal of Industrial Ergonomics","volume":null,"pages":null},"PeriodicalIF":3.1,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139480067","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}

Using transportation access to maternal health services as a case study, this research sought to enhance the patient work system framework to include sub-factors specific to SDOH. Following a model of community-based participatory research, semi-structured interviews were conducted with 18 individuals who were pregnant within the last five years, identified as low-income, and identified as having one or more racial or ethnic minoritized identities. Thirty-three secondary themes and 28 tertiary themes were derived inductively under the deductive framework of the consolidated patient work system. Unique sub-factors of the patient work system were identified, expanding our current understanding of the dimensionalities of the patient work system. Sub-factors were mostly expanded in the domains of the physical and organizational environments. HF/E researchers and practitioners, in partnership with other disciplines and communities, should expand work system models to purposefully incorporate a range of work system factors that stem from SDOH. Extending these models produces a holistic view of systems, providing a better foundation to align design interventions with the contextual realities of marginalized populations who experience health inequities.</p></div>","PeriodicalId":50317,"journal":{"name":"International Journal of Industrial Ergonomics","volume":null,"pages":null},"PeriodicalIF":3.1,"publicationDate":"2023-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0169814123001208/pdfft?md5=2d4d6c52562f819911c0b035b618d3b9&pid=1-s2.0-S0169814123001208-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138570509","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
