This study investigates how five selected upper-body parameters, including Neck Angle (NA), Head Angle (HA), Shoulder Alignment Angle (SAA), Thoracic Kyphosis Angle (TKA), and Sitting Acromial Height (SAH), are related to the measures of human-seat interaction in headrest region, which involve the perceived comfort, contact loading, and muscle activity. Experiments with 25 participants were carried out on a conventional aircraft seat at different conditions to identify and understand the significant upper body parameters that affect the human-seat interaction through cross-correlation analyses. The results show the occupant's initial HA, SAH, and SAA are correlated with multiple human-seat interaction measures for general seating. Among the body parameters investigated, HA appears to be the most influential factor in the seating experience in the upper body region under various sitting conditions. The head movement (

Δ H A

) with different backrest inclinations is found to be closely associated with the headrest contact loading. This study highlights the dependence of the sitting experience on the characteristics of an individual's natural upper-body position and movement when seated, considering both subjective and objective measures. The findings from this study can be used as anthropometric reference guidelines in seat design and optimization to satisfy more customized demands from the perspective of the individual's body characteristics.

Southern Spain (Andalusia) is the only region in Europe capable of producing tropical fruits (avocado, cherimoya, and mango). The sector employs more than 4000 workers. The objective of this research is the integrated assessment of musculoskeletal symptoms and psychosocial factors of tropical crop workers in Andalusia using the 'Standardised Nordic questionnaires for the analysis of musculoskeletal symptoms (NMQ)' and 'Mini Psychosocial Factors (MPF) method'. NMQ is a 28-question multiple-choice questionnaire covering the neck, shoulders, elbows, wrists/hands, back, hips, knees, and ankles. The MPF method comprises 15 questions and analyses a total of 12 psychosocial variables (Autonomy, Compensation, Control, Demands, Emotional, Health, Mental Load, Mobbing, Recognition, Relationships, Rhythm, and Support). In total, 401 interviews were completed with an error/accuracy of 4.66%. The method for selecting the agricultural plots where the workers work was carried out in a random, non-stratified way using UTM (Universal Transverse Mercator) coordinates. Multiple correspondence analysis, the Burt table, and descriptive statistics (with a chi-square test) were used to analyse the results. The results indicate that no high risk exists in any of the psychosocial factor although there is a medium risk. The psychosocial factor "Compensation" stands out. Musculoskeletal symptoms are identified in the back and neck. The symptoms do not prevent the workers from performing their agricultural tasks. Furthermore, the drought conditions over the last three agricultural seasons had the impact of decreasing agricultural wages, and this was slightly detected as an effect on the workers’ moral and economic recognition.

Frequent occupational accidents in the construction industry highlight the significance of improving workers' safety performance (SP), particularly among young workers (YWs, i.e., Millennials and Generation Z), who suffer more occupational injuries. Drawing on the social learning theory and job demands-resources theory, this study attempts to uncover how the resilient safety culture (RSC) of construction organizations boosts the SP of YWs. A mixed research design, combining the “top-down” empirical study and the “bottom-up” agent-based modeling (ABM) simulation experiment was developed in this study. First, a moderated mediation model was developed wherein job crafting served as a mediator, while supervisor support and coworker support were considered as boundary conditions. Using 218 samples of YWs from construction projects in China, the proposed theoretical model was validated by the structural equation modeling approach. Based on the empirical results, an ABM experiment was subsequently conducted to dynamically exhibit the SP emergent process of YWs. The empirical results affirmed that RSC significantly enhanced the SP of YWs, and job crafting was a mediator between this link. Supervisor support was found to amplify the positive impact of RSC on YWs’ job crafting and further enhance their SP, while coworker support played the opposite moderating role. In addition, the results of ABM experiment further reinforced the cross-section findings of the empirical study with a dynamic picture. This study advances the RSC research in the broad industrial and occupational ergonomics field by emphasizing its potential as an effective approach to enhancing productivity, health, and safety in construction workplaces. Additionally, it offers valuable practical insights on how to leverage RSC to improve the SP of YWs, thus effectively reducing human factor-related accidents.

建筑行业频繁发生的工伤事故凸显了提高工人安全绩效（SP）的重要性，尤其是对遭受工伤较多的年轻工人（即千禧一代和 Z 世代）而言。本研究借鉴社会学习理论和工作需求-资源理论，试图揭示建筑组织的弹性安全文化（RSC）如何提高青年工人的安全绩效。本研究采用混合研究设计，将 "自上而下 "的实证研究与 "自下而上 "的代理建模（ABM）模拟实验相结合。首先，研究人员建立了一个中介模型，将工作设计作为中介因素，而将上司支持和同事支持作为边界条件。利用来自中国建筑项目的 218 个青工样本，通过结构方程建模法对所提出的理论模型进行了验证。在实证结果的基础上，还进行了一个 ABM 实验，以动态展示青工的 SP 涌现过程。实证结果证实，RSC 显著增强了青年女工的 SP，而工作雕琢是这一联系的中介。研究发现，上司的支持放大了 RSC 对青年妇女工作设计的积极影响，进一步增强了青年妇女的工作设计，而同事的支持则起到了相反的调节作用。此外，ABM 实验的结果以动态的方式进一步证实了实证研究的横截面结论。本研究强调了 RSC 作为提高建筑工作场所生产率、健康和安全的有效方法的潜力，从而推进了 RSC 在广泛的工业和职业工效学领域的研究。此外，它还就如何利用 RSC 改善青年工人的 SP，从而有效减少与人为因素相关的事故提供了宝贵的实用见解。

This study adopted a mixed-method approach to identify attractiveness factors from multiple perspectives. First, a qualitative survey (Survey 1) was performed to obtain the hypothesis factors of three retro products by analyzing user experiences using the UX curve method and the KJ method. From these results, nine categories were extracted as hypothesized factors that create attractiveness in the use of retro products. Second, a quantitative web-based questionnaire (Survey 2) was conducted to verify the hypothesized factors. The questionnaire items were created based on the nine hypothesized factors extracted from Survey 1. Next, a five-factor model of the attractiveness of retro products was extracted through factor analysis of the results from Survey 2. The five factors are: “excitement,” “attractiveness due to time and effort,” “instinctive attractiveness,” “attractiveness due to inconvenience,” and “novelty. Finally, multiple regression analysis was performed, which revealed that "attractiveness due to time and effort,” “instinctive attractiveness,” “attractiveness due to inconvenience,” and “novelty. Finally, multiple regression analysis was performed, which revealed that "attractiveness due to time and effort" and "instinctive attractiveness" have the greatest impact on the attractiveness of retro products.

Load transfer during lifting leads to increased postural perturbations that may compromise postural stability, so lifting is an occupational task associated with high fall risk. This study aimed to gain improved knowledge about fall risk in lifting tasks. The effects of both load weight and load knowledge were examined. Load weight was set at three levels according to individuals' maximum acceptable lifting capacity. Unlike previous studies, load knowledge was set by considering load material fragility. Twenty-four male participants were involved in the experimental study, in which they were instructed to perform both symmetric and asymmetric lifting tasks under conditions defined by various combinations of load weight and load knowledge. Fall risk was assessed by using measures accounting for postural stability and risk of slips. The results showed that when being defined near individuals’ maximum acceptable lifting capacity, increased lifting load weight not only improved postural stability in the rising phase of lifting, but also increased the risk of slips. These findings suggest that improved postural stability due to increased load weight in the rising phase could be a compensatory postural control strategy for the increased risk of slips so as to maintain balance and avoid the occurrence of a potential fall. We also found that load knowledge of fragility and weight may not contribute to fall risk reduction during lifting. The findings obtained from the present study are useful for practitioners to design safe lifting tasks.

Foreign object intrusion on railway tracks poses a significant safety threat to train operations. In this study, we investigate the impact of train operating speed on drivers’ hazard perception (HP). For this purpose, we developed a hazard perception test (HPT) system, simulating scenarios of foreign object intrusion on railway tracks using high-fidelity computer animation techniques. Thirty certified participants, who had passed the train driver psychological qualification test, participated in the HPT across four speed classes: 120 km/h, 160 km/h, 250 km/h, and 350 km/h, the maximum speeds of the levels 0–3 of the Chinese Train Control System in service. The analysis revealed that as speed increases, there is a significant decrease in HP response time, an intensification of visual tunneling, and a significant reduction in the leftward bias of visuospatial attention. These results highlight the critical role of speed in influencing HP and carry significant implications for the deployment of assistive technological systems for hazard detection and the enhancement of train design, especially in the context of high-speed railways.

The advent of Industry 4.0 has transformed manufacturing by incorporating industrial robots to boost productivity and quality while cutting costs. Human-Robot Collaboration (HRC) is central to this shift, emphasizing seamless cooperation between humans and robots in shared workspaces. Evaluating the impact of such collaboration on human operators is crucial for efficiency, safety, and well-being. This systematic review explores methodologies for assessing human factors in HRC environments, spanning psychological, cognitive, and physical realms. Various evaluation methods have been identified, from subjective questionnaires to objective measurements. While subjective methods are the standard (especially questionnaires), there is a growing trend towards integrating physiological and physical measurements. The blend of subjective and objective methods offers a holistic understanding of human-robot interaction. This review adopts a more technical-oriented approach in the assessment of human factors in HRC. As a result, it consolidates existing methodologies and suggests avenues for further research, highlighting the significance of this assessment for enhancing productivity, safety, and well-being in industrial settings.

Discovering hidden strengths: How a passive lower extremity exoskeleton boosts the isometric pulling capacity to new heights 发现隐藏的力量：被动下肢外骨骼如何将等长牵拉能力提升到新高度

Wearable exoskeletons aim to balance physical work demands and individual capacity. This study assessed isometric pushing capacities in various directions using a chair-type exoskeleton (CEX) at different heights. Twenty participants of both genders underwent forward, backward, upward and sideways pushing. Using CEX increased posterior pushing by over 60%, decreased lateral pushing about 10%, but had no significant effect on anterior or superior pushing capacities. The weight distribution on the feet rose to 80% in posterior pushing and dropped to 20% in anterior pushing, while weight distribution between the feet and CEX, measured with two force plates, was about 5:5 in superior and lateral pushing. Despite increased posterior pushing, decrease in posterior stability with CEX should be considered.

可穿戴外骨骼旨在平衡体力劳动需求和个人能力。本研究使用不同高度的椅子型外骨骼（CEX）对不同方向的等距推举能力进行了评估。20 名男女参与者分别进行了向前、向后、向上和向侧的推举。使用 CEX 使后推力增加了 60%以上，侧推力减少了约 10%，但对前推力和上推力没有显著影响。在后推时，脚部的重量分布上升到 80%，而在前推时则下降到 20%，而在上推和侧推时，用两块力板测量的脚部和 CEX 之间的重量分布约为 5:5。尽管后推力增加，但应考虑到 CEX 后稳定性的下降。工人和外骨骼设计者应意识到推举能力增加与后部姿势稳定性降低之间的权衡。在采取适当的预防措施以降低跌倒风险的情况下，采用 CEX 对需要在较低位置拉动物体的工人尤其有益。

The U.S. Bureau of Labor Statistics projects that by the year 2029, the United States will lose a million jobs in the office and administrative support occupations because technology, automation, and artificial intelligence (AI) have the potential to substitute or replace the office and administrative functions performed by office workers. Despite the potential impact AI will have on office work and the important role office workers play in the American economy, we have limited knowledge of the state of the art research in office work at the intersection of emerging artificial intelligence technologies. In this study, we conducted a bibliometric analysis of the scholarly literature at the intersection of office work, office automation and artificial intelligence. We extracted literature sources from Compendex and Scopus databases and used VOSviewer for visualizing and quantifying our bibliometric analyses. Our findings from keywords analysis indicate that office automation, humans, human-computer interaction, and artificial intelligence occurred more frequently in the scholarly literature and had high link strengths. Keyword clusters from co-occurrence analysis indicate that intelligent buildings, robotics, and the internet of things are emerging topics in the office work domain. The two clusters related to ergonomics, worker characteristics, human performance, and safety indicate the types of human factors concerns that are more widely studied in office work settings. In summary, our findings on the state-of-the-art research in office work indicate that more studies have been conducted on smart buildings, robotics, and technology development for office work, compared to studies on office workers and their professional development.

Relevance to industry

This review on the state-of-the-art in research on office work is relevant in every industry that has the potential to undergo significant changes due to AI in the future.

美国劳工统计局预计，到 2029 年，美国将失去一百万个办公室和行政支持职业的工作岗位，因为技术、自动化和人工智能（AI）有可能替代或取代办公室工作人员所从事的办公室和行政职能。尽管人工智能将对办公室工作产生潜在影响，而且办公室工作人员在美国经济中发挥着重要作用，但我们对新兴人工智能技术交叉领域的办公室工作研究现状了解有限。在本研究中，我们对办公室工作、办公自动化和人工智能交叉领域的学术文献进行了文献计量分析。我们从 Compendex 和 Scopus 数据库中提取文献资料，并使用 VOSviewer 对文献计量分析进行可视化和量化。关键词分析结果表明，办公自动化、人类、人机交互和人工智能在学术文献中出现的频率较高，链接强度也较高。共现分析的关键词群表明，智能建筑、机器人和物联网是办公领域的新兴主题。与人体工程学、工人特征、人的表现和安全相关的两个群组表明，办公室工作环境中更广泛研究的是人为因素问题的类型。总之，我们对办公室工作领域最新研究的结果表明，与对办公室工作人员及其职业发展的研究相比，对智能建筑、机器人技术和办公室工作技术发展的研究较多。

The mastectomy bra (M-bra) serves as an essential rehabilitative product for individuals who have undergone breast cancer surgery. This study aimed to develop an ergonomic design method for M-bras that addresses both the physiological and psychological needs of post-mastectomy breast cancer patients. Over 270 M-bras with diverse design options were collected from online markets, and more than 100 post-mastectomy patients participated in an online survey to rank their preferences regarding eight M-bra components and 19 design options. An orthogonal experimental design was applied to reduce the vast array of design combinations to 20 M-bra test samples. The Pleasure-Arousal-Dominance (PAD) emotion model and the Self-Assessment Manikin (SAM) scale were then used to collect PAD scores from 40 patients evaluating these test samples. Extreme difference analysis was conducted to evaluate the significance of the M-bra components and identify combinations that generated the highest and lowest PAD levels. Based on the PAD scores, 11 samples were categorized as "delighted" or "relaxed" M-bras due to their positive emotional polarity. Linear regression analysis showed strong correlations between the design options and PAD scores, with R² values of 0.962 for P, 0.819 for A, and 0.949 for D. A backpropagation neural network was developed to predict PAD values for various M-bra design options, achieving prediction errors of 8.06% for P, 6.15% for A, and 13.29% for D, demonstrating satisfactory performance given the subjective nature of the evaluations.

乳房切除术胸罩（M-bra）是乳腺癌术后患者必不可少的康复产品。本研究旨在开发一种符合人体工程学的胸罩设计方法，以满足乳腺癌切除术后患者的生理和心理需求。研究人员从网上市场收集了 270 多种不同设计方案的 M 型胸罩，并对 100 多名乳腺癌术后患者进行了在线调查，以了解他们对 8 种 M 型胸罩组件和 19 种设计方案的偏好程度。采用正交实验设计将大量设计组合减少到 20 个 M-bra 测试样本。然后使用愉悦-烦恼-主导（PAD）情绪模型和自评量表（SAM）收集了 40 名患者对这些测试样本的 PAD 评分。通过极差分析来评估 M-bra 成分的重要性，并确定产生最高和最低 PAD 水平的组合。根据 PAD 分数，11 个样本因其积极的情绪极性而被归类为 "愉悦 "或 "放松 "M-bra。线性回归分析表明，设计方案与 PAD 分数之间具有很强的相关性，P 的 R2 值为 0.962，A 为 0.819，D 为 0.949。我们开发了一个反向传播神经网络来预测各种 M-bra 设计方案的 PAD 值，P 的预测误差为 8.06%，A 的预测误差为 6.15%，D 的预测误差为 13.29%，考虑到评价的主观性，其表现令人满意。
