The COVID-19 pandemic demonstrated the need for respiratory protection against airborne pathogens. Respirator options for children are limited, and existing designs do not consider differences in facial shape or size. We created a dataset of children's facial images from three cohorts, then used geometric morphometric analyses of dense and sparse facial landmark representations to quantify age, sex and ancestry-related variation in shape. We found facial shape and size in children vary significantly with age from ages 2 to 18, particularly in dimensions relevant to respirator design. Sex differences are small throughout most of the age range of our sample. Ancestry is associated with significant facial shape variation in dimensions that may affect respirator fit. We offer guidance on how to our results can be used for the appropriate design of devices such as respirators for pediatric populations. We also highlight the need to consider ancestry-related variation in facial morphology to promote equitable, inclusive products.

The purpose of this study was to gather ergonomists’ perspectives and experiences, describing current challenges and contextual considerations in risk assessment, exploring how ergonomists are currently integrating the multiple domains of ergonomics for MSD and/or psychological health and safety and highlighting key considerations in the design and format of future tools.
In-depth, semi-structured interviews were conducted with twenty Canadian ergonomists to explore risk assessment tool use, favoured characteristics and format of tools, commonly addressed risk factors in their practice, and tools relating to both MSD prevention and psychological health and safety. The range of practitioner years of experience highlighted differing needs and approaches to the use and formatting of risk assessment tools. Practitioners reported using quantitative outcomes (levels of risk, values) from traditional physical tools complemented by a general observation of psychosocial or organizational factors. Though many respondents had not yet encountered the need for psychological injury assessment in their sectors it was identified as a quickly emerging area citing a need for valid and reliable tools. Practitioners noted a lack of available tools that integrated cognitive and psychosocial items presenting a future challenge for integrated tools that covered multiple ergonomic domains. Along with recommendations for future tool development, the authors reflect on the process of qualitative inquiry as an essential step in the risk assessment process. Future studies will be needed to develop and evaluate measurement properties of integrating psychosocial factors and their respective tools in traditional MSD assessment.

Heavy vehicle operators suffer from increased fall risk, potentially due to exposure to whole-body vibration (WBV) that compromises postural control. This study aimed to characterize the relative impacts of multi-axial WBV vs. vertical-dominant WBV on dynamic postural control during sit-to-stand transition and stair descent, following prolonged vibration exposures. We also compared the effectiveness of a standard (single-axial passive suspension) seat with a multi-axial active suspension seat intervention. Vertical-dominant WBV adversely affected dynamic postural control. However, multi-axial WBV had no added adverse effects on postural control compared to vertical-dominant WBV. The multi-axial active suspension system did not outperform the standard seat in mitigating vibration effects on postural control during exposures but led to faster recovery during breaks between exposures. Overall, our results confirmed the negative effects of WBV on dynamic postural control but did not detect any additional negative effects associated with multi-axial WBV when compared to vertical-dominant WBV.

The aim of this paper is to identify some of the characteristics of innovation and collective work in different fablab organizations. We first define fablabs through a review of literature, situating related questions in the field of ergonomics and focusing our point of view on individual and collective activity. Secondly, we show how the results of our qualitative analyses (performed on data from interviews and observations of fablab managers, users, and projects from 13 fablabs) reveal 3 main types of fablab organization: community-oriented fablabs, academic fablabs and industrial fablabs, in which different activities are carried out. Fablab activity depends on lab users and the type of design projects carried out. The discussion will focus on the fablab organization findings, including the links between design/innovation project work, collective work and evolving rules, and how all of these aspects might direct activity-centered ergonomics research and actions in the future.

This study aims to explore adoption barriers from three aspects critical to facilitating robotic-assisted-surgery (RAS) adoption: the human-robot-interaction, built-environment, and training. Guidelines for research and design are identified from these perspectives. This study consisted of three phases: 1) surveys to RAS stakeholders and a crowd-sourcing survey; 2) stakeholder focus groups; and 3) a workshop with subject-matter experts to prioritize future research for RAS. Barriers from the human-robot-interaction perspective include hesitancy among clinicians to trust automation and physical discomfort during prolonged RAS. Barriers impeding communication and workflow disruptions were identified considering the built-environment. Training barriers were exemplified by varying curriculums from formal (courses) to informal (peer training) for surgeons. Crowd-sourced survey results suggest socio-economic status plays a role in RAS perception. Design guidelines include: 1) improved ergonomics; 2) deliberate introduction of automation; 3) sufficient in-room storage for prospective operating rooms; and 4) the development of compact RAS devices for older/smaller rooms.

This study investigated whether caregivers and regulatory experts can predict the appeal of household chemicals for children and explored determinants of differences between adults' and children's child-appeal rating. We invited N = 95 4-year-old children and their caregivers to a laboratory study. Both independently ranked 16 household chemicals from the least to the most child-appealing product. In addition to the laboratory study, we sent an online adaptation of this ranking task to N = 46 experts involved in the monitoring and authorizing of household chemicals. Our findings show that the aggregated child-appeal rating of household chemicals was highly similar among caregivers, experts, and children. When comparing child-appeal ratings of household chemicals with and without child-appealing images, caregivers and experts did well in predicting which products might appeal to children. Finally, our findings show that the similarity between individual caregivers' and their own children's child-appeal ratings of household chemicals varied substantially. To conclude, although adults can assess the general child-appeal of household chemicals, they need to consider that the actual appeal of a household chemical can vary considerably among individual children. Instead of regulating specific product attributes, policymakers should prioritize educating caregivers about pitfalls and misconceptions that hinder effective injury prevention.
本研究调查了看护者和监管专家能否预测家用化学品对儿童的吸引力，并探讨了成人和儿童对儿童吸引力评级差异的决定因素。我们邀请了 N = 95 名 4 岁儿童及其看护人参加实验室研究。两人分别对 16 种家用化学品从最不吸引儿童的产品到最吸引儿童的产品进行排序。除实验室研究外，我们还向 N = 46 名参与家用化学品监控和授权的专家发送了这一排名任务的在线改编版。我们的研究结果表明，照料者、专家和儿童对家用化学品的儿童喜爱度综合评分非常相似。在比较有和没有儿童吸引力图像的家用化学品的儿童吸引力评级时，护理人员和专家在预测哪些产品可能吸引儿童方面表现良好。最后，我们的研究结果表明，个别照顾者和他们自己的孩子对家用化学品的儿童吸引力评级之间的相似度差别很大。总之，尽管成人可以对家用化学品的一般儿童吸引力进行评估，但他们需要考虑到不同儿童对家用化学品的实际吸引力可能会有很大差异。政策制定者应该优先教育看护者认识到妨碍有效预防伤害的陷阱和误解，而不是对具体的产品属性进行监管。

Back exosuits offer the potential to reduce occupational back injuries but require in-field acceptance and use to realize this potential. For this study, 146 employees trialed an active back exosuit in the field for 4 h, completing an acceptance usability survey. Comparing the 80% of employees willing to continue wearing this device (N = 117) to those who were not (N = 29) revealed that employees willing to wear this device for a longer-term study generally were more likely to perceive this back exosuit to be effective (helpful) and compatible (minimally disruptive) to their everyday work. Using an optimal tree approach, we demonstrate that intent-to-use could be predicted with 78% accuracy by interacting features of perceived exosuit effectiveness and work compatibility. This study reinforces the importance of task matching, noticeable relief, and unobtrusive design to facilitate short-term employee acceptance of industrial wearable robotic technology.

Work-related psychosocial hazards have a significant influence on the development of musculoskeletal and mental health disorders (MSDs and MHDs). This study used behavioural change theory to guide understanding of barriers and enablers for leaders working in the Heavy Vehicle Road Transport industry, to address workplace psychosocial hazards. The findings will be used to inform design of a future intervention to support leaders to more effectively address these hazards. Principal results and major conclusions: A higher number of barriers than enablers were identified. The most prevalent barriers were inadequate knowledge and interpersonal skills, and environmental context and inadequate resources, and the most prevalent enabler was risk management. The findings extend previous evidence by providing more specific detail regarding requirements for addressing psychosocial hazards. Further, the findings identified there is a need to improve the capability, opportunity and motivation of leaders to enable them to more effectively address psychosocial hazards.

Technical devices can enhance safety by warning people of unrecognized obstacles, particularly in traffic, wilderness, and industrial settings. This study aims to identify the most effective vibrotactile stimuli for localization tasks by developing and evaluating various types of vibrotactile alerts presented through a tactile vest with visual patterns. The study design involved comparing the time and consistency of interpreting visual stimuli and subsequent tactile stimuli. The tactile stimuli included: a ’point’ vibration on the left or right side of the back, a ’column’ pattern of five vibrations on one side of the back, and a ’wave’ pattern of vibrations running along the back from left to right or vice versa. The results indicated that reaction times to visual stimuli were significantly shorter than to vibration stimuli, suggesting that visual stimuli are suitable for alert systems with low cognitive load. The ’point’ and ’column’ patterns were recognized significantly faster and more clearly than the’wave’ pattern. Consequently, the haptic vest was classified as a potentially effective low cognitive load device in localization performance. The findings could inform the design of early warning systems for obstacle detection in real traffic situations.

With the emergence of Industry 5.0 and an increasing focus on human-centric approaches in manufacturing, the analysis of workers in production systems has gathered significant interest among researchers and practitioners. Previous studies have explored the impact of various aspects, such as skills, fatigue, and circadian rhythms, on human performance. However, the cumulative effect of these aspects as disturbances on work performance has yet to be fully elucidated. This study introduces an approach using the Functional Resonance Analysis Method (FRAM) to investigate the impact of multiple disturbances on workers’ performance. Furthermore, this approach explored how the resilience-related skill aspects of workers affect their performance under multiple disturbances. A case study on engine test and repair processes was conducted, employing qualitative data collection and semi-quantitative simulation studies examining the impact of combined disturbances across 4,094 scenarios. The results show that a larger number of compounded variabilities expressed in Common Performance Conditions (CPCs) made it significantly challenging to recover work performance, and CPCs with particularly critical effects were identified.

随着工业 5.0 的出现以及制造业越来越重视以人为本的方法，研究人员和从业人员对生产系统中工人的分析产生了浓厚的兴趣。以往的研究探讨了技能、疲劳和昼夜节律等各个方面对人类工作表现的影响。然而，这些方面作为干扰因素对工作绩效的累积影响尚未完全阐明。本研究采用功能共振分析法（FRAM）来研究多重干扰对工人工作表现的影响。此外，该方法还探讨了在多重干扰下，工人与恢复力相关的技能方面如何影响其工作表现。通过定性数据收集和半定量模拟研究，对发动机测试和维修流程进行了案例研究，考察了 4,094 种情况下综合干扰的影响。研究结果表明，以共同性能条件（CPC）表示的大量复合变异使得恢复工作性能面临巨大挑战，并确定了具有特别关键影响的 CPC。此外，熟练工人的 FRAM 模型在更多情况下都能保持较高的绩效。本研究的方法表明，它能够在考虑复杂干扰的同时，为有效、安全地管理生产系统提供见解。

Previous studies have explored the impact of various aspects, such as skills, fatigue, and circadian rhythms, on human performance. However, the cumulative effect of these aspects as disturbances on work performance has yet to be fully elucidated. This study introduces an approach using the Functional Resonance Analysis Method (FRAM) to investigate the impact of multiple disturbances on workers’ performance. Furthermore, this approach explored how the resilience-related skill aspects of workers affect their performance under multiple disturbances. A case study on engine test and repair processes was conducted, employing qualitative data collection and semi-quantitative simulation studies examining the impact of combined disturbances across 4,094 scenarios. The results show that a larger number of compounded variabilities expressed in Common Performance Conditions (CPCs) made it significantly challenging to recover work performance, and CPCs with particularly critical effects were identified. In addition, the FRAM model of skilled workers was shown to sustain higher performance across more scenarios. The approach of this study has demonstrated its ability to provide insights for effectively and safely managing production systems while considering complex disturbances.</div></div>","PeriodicalId":55502,"journal":{"name":"Applied Ergonomics","volume":"122 ","pages":"Article 104391"},"PeriodicalIF":3.1,"publicationDate":"2024-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142333021","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}
