One way to provide assistance in a dynamic lifting task is to pre-emptively move the exoskeleton based on a predicted reference trajectory. However, the level of aggressiveness in the prediction (i.e., how far ahead in time) and the exoskeleton's degree of adherence to the reference trajectory (stiffness) are not yet fully understood. This study investigated the effects of stiffness and pre-emptive offset parameters in an impedance-controlled robotic arm on muscle activation and perceived exertion of the user. Thirteen participants were instructed to lift a load equivalent to 15% of their maximal voluntary contracted force in collaboration with a robotic arm with 40°–135° of elbow flexion in 1.12 s. Three levels of stiffness (lower: 0.1 N m deg⁻¹, medium: 0.2 N m deg⁻¹, and higher: 0.31 N m deg⁻¹) and two levels of pre-emptive offsets (shorter: 0.1 s and longer: 0.4 s) were investigated. We found that (1) during 0–0.5 s (acceleration stage) of elbow flexion, a higher stiffness level and a longer pre-emptive offset decreased muscle activity; (2) during 0.5–1 s (deceleration stage) of elbow flexion, medium and higher stiffness with a shorter pre-emptive offset decreased muscle activity; (3) the perceived exertion and assistance of participants were improved with a higher stiffness and a longer pre-emptive offset, whereas cooperation was rated higher at a shorter pre-emptive offset under higher stiffness. This study reveals that the optimal parameters for stiffness and pre-emptive offsets for predictive impedance controls are different for different stages of elbow flexion.

在动态提升任务中提供帮助的一种方法是根据预测的参考轨迹预先移动外骨骼。然而，预测的积极程度（即提前多长时间）和外骨骼对参考轨迹的依附程度（刚度）尚未完全明了。本研究调查了阻抗控制机械臂的刚度和预先偏移参数对肌肉激活和使用者感知用力的影响。13 名参与者被要求在 1.12 秒内与机械臂合作举起相当于其最大自主收缩力 15%的重物，肘关节屈曲 40°-135°。研究了三种刚度水平（较低：0.1 N m deg-1；中等：0.2 N m deg-1；较高：0.31 N m deg-1）和两种抢先偏移水平（较短：0.1 秒；较长：0.4 秒）。我们发现：(1) 在屈肘 0-0.5 秒（加速阶段）期间，较高的硬度水平和较长的抢先偏移降低了肌肉活动；(2) 在屈肘 0.5-1 秒（减速阶段）期间，中等和较高的硬度水平和较短的抢先偏移降低了肌肉活动；(3) 在较高的硬度水平和较长的抢先偏移下，参与者的感知用力和协助得到改善，而在较高的硬度水平和较短的抢先偏移下，参与者的合作性评分较高。这项研究揭示了预测阻抗控制的僵硬度和抢先偏移的最佳参数在肘关节屈曲的不同阶段是不同的。

The dynamics and frequency of change in today's workplaces force organizations to address the question of how to create optimal conditions for facilitating adaptation to change. Identifying critical factors that affect performance and well-being in change situations can help answer this question. Given the need for applied research in this area, the aim of this paper is to investigate whether the way of change implementation has an impact on performance and well-being. Additionally, retentivity and specific self-efficacy as individual factors are exploratorily investigated. In an experimental study, seventy-one participants learned and trained specific manufacturing steps in a simulated production environment. Subsequently, they had to adapt the trained task execution as some of the previously learned manufacturing steps were subject to change. The changes were implemented a) either in a stepwise manner or b) all at once. The executed manufacturing steps were recorded, enabling the calculation of task execution time and classification of adaptation errors. The results of Mann-Whitney-U-tests showed that the stepwise introduction of changes led to significantly faster task execution time than the change introduction all at once. Additionally, descriptive statistics indicated fewer adaptation errors but higher frustration. Our exploratory analysis showed a significant negative relationship between retentivity and task execution time, as well as between specific self-efficacy and frustration. Stepwise change introduction seems to be beneficial for adaptation, even though emotional responses and individual factors must be considered.

当今工作场所变化的动态性和频繁性迫使组织解决如何创造最佳条件以促进适应变化的问题。找出在变革情况下影响绩效和福利的关键因素有助于回答这个问题。鉴于该领域需要应用研究，本文旨在调查变革实施方式是否会对绩效和幸福感产生影响。此外，本文还对作为个体因素的缄默性和特定自我效能感进行了探索性研究。在一项实验研究中，71 名参与者在模拟生产环境中学习和训练了特定的生产步骤。随后，他们必须调整训练后的任务执行，因为之前学习的一些生产步骤可能会发生变化。这些变化可以 a) 逐步实施，也可以 b) 一次性实施。对执行的生产步骤进行记录，以便计算任务执行时间和对适应错误进行分类。Mann-Whitney-U 检验的结果表明，逐步引入变革的任务执行时间明显快于一次性引入变革的任务执行时间。此外，描述性统计表明，适应错误较少，但挫败感较高。我们的探索性分析表明，缄默性与任务执行时间之间以及特定自我效能感与挫败感之间存在显著的负相关。尽管必须考虑情绪反应和个人因素，但逐步引入变化似乎有利于适应。

Numerous flight accidents have been attributed to pilots' lack of situation awareness (SA), with distraction being a significant contributing factor. Therefore, identifying factors that may protect pilots' SA under distraction conditions and explore their mechanisms is crucial for promoting aviation safety. This study empirically investigates the effects of individual differences in working memory capacity (WMC) on pilots' SA when performing secondary tasks. The pilots were divided into two groups based on their performance on the WMC test and were asked to complete a simulated cockpit monitoring task under three secondary task difficulty conditions (no task, low-difficulty task, and high-difficulty task). SA in the simulated monitoring tasks was measured using the Situation Awareness Global Assessment Technique (SAGAT), and eye movement data were collected to analyze visual behaviors and attention allocation. Results showed that the difficulty of secondary task significantly impacted overall SA, the perceptual level of SA and dwell times; however, secondary task difficulty did not affect the perceptual level of SA in pilots with high WMC. These results suggest that WMC protects pilots' perceptual level SA when they perform secondary tasks. This study provides additional insights into the mechanisms of working memory in protecting SA and offers theoretical guidance for the design of complex technical systems and pilot psychological selection, which can help promote aviation safety.

许多飞行事故都归咎于飞行员缺乏态势感知（SA），而分心是一个重要的诱因。因此，确定在分心条件下保护飞行员态势感知的因素并探索其机制对于促进航空安全至关重要。本研究实证调查了工作记忆能力（WMC）的个体差异对飞行员执行次要任务时的 SA 的影响。根据飞行员在工作记忆容量测试中的表现将他们分为两组，并要求他们在三种次要任务难度条件下（无任务、低难度任务和高难度任务）完成模拟驾驶舱监控任务。在模拟监控任务中，使用情境意识总体评估技术（SAGAT）测量SA，并收集眼动数据来分析视觉行为和注意力分配。结果表明，次要任务的难度对总体SA、SA的感知水平和停留时间有显著影响；然而，次要任务的难度并不影响高WMC飞行员的SA感知水平。这些结果表明，当飞行员执行次要任务时，WMC 可以保护飞行员的感知水平 SA。本研究为工作记忆保护SA的机制提供了更多见解，为复杂技术系统的设计和飞行员心理选择提供了理论指导，有助于促进航空安全。

Work from home (WFH) may result in less physical activity and more sedentary behaviour among office employees. The consequence to body pain is unknown. The aim of this study was to assess longitudinal sedentary behaviour change and pain association among office workers who have been working from home. Baseline survey was administered to a cohort of office employees in January–February 2020. In March, all employees started to work from home in response to the COVID-19 pandemic. The additional surveys took place in April, June, and December 2020. The survey consisted of IPAQ, which included sitting time report, along with self-reported proportion of time spent standing during work, and body pain. Generalized estimating equations were used to analyse the trends in pain scores, and their associations to sitting time and standing frequency. The cohort consisted of 143 participants at baseline. Participants reported lower pain scores for neck (risk ratio = 0.90, CI = 0.82–0.99) and back (risk ratio = 0.85, CI = 0.75–0.96) in December, compared with pain scores at baseline. Neck pain among participants with more standing was lower than those with infrequent standing (risk ratio = 0.87, CI = 0.79–0.96). Weekly sitting time had no statistically significant effect on body pain scores. For WFH employees, more standing appears to have a significant protective effect on the neck. Being more sedentary during work does not have a clear detrimental effect on long-term musculoskeletal health.

在家办公（WFH）可能会导致办公室员工的体力活动减少，久坐行为增多。其对身体疼痛的影响尚不清楚。本研究的目的是评估在家工作的上班族的纵向久坐行为变化和疼痛关联。2020 年 1 月至 2 月，对一批办公室员工进行了基线调查。3 月，为应对 COVID-19 大流行，所有员工开始在家工作。附加调查分别于 2020 年 4 月、6 月和 12 月进行。调查内容包括 IPAQ，其中包括坐姿时间报告、工作期间站立时间的自我报告比例以及身体疼痛。采用广义估计方程分析疼痛评分的趋势及其与坐立时间和站立频率的关系。研究组共有 143 名基线参与者。与基线时的疼痛评分相比，参与者在 12 月份的颈部（风险比 = 0.90，CI = 0.82-0.99）和背部（风险比 = 0.85，CI = 0.75-0.96）疼痛评分较低。经常站立者的颈部疼痛低于不经常站立者（风险比 = 0.87，CI = 0.79-0.96）。每周坐着的时间对身体疼痛评分没有明显的统计学影响。对于全职工作的员工来说，多站似乎对颈部有明显的保护作用。工作期间久坐对长期肌肉骨骼健康没有明显的不利影响。

Household refrigerator concepts have evolved with changing applicational scenarios and requirements, providing users with support for healthy eating, personal care, and other activities in the kitchen and other areas of the home. However, current research on exploring user expectations and requirements for household refrigerators lacks considering the perspective of applicational scenarios and activity support. For this study, we invited 45 participants to explore immersive experience methods and conducted semi-structured interviews to investigate user requirements for future household refrigerators in different home areas and obtain dimensional details related to user needs, ultimately generating new insights into the demand for connected, intelligent, emotional, easy to use. Our findings are instructive for the design of future refrigerators in household scenarios and provide guidance and references for the design of other smart home appliances.

家用冰箱的概念随着应用场景和需求的变化而发展，为用户在厨房和家庭其他区域的健康饮食、个人护理和其他活动提供支持。然而，目前关于探索用户对家用冰箱的期望和要求的研究缺乏对应用场景和活动支持角度的考虑。在这项研究中，我们邀请了 45 位参与者探索沉浸式体验方法，并进行了半结构式访谈，以调查未来家用冰箱在不同家居区域的用户需求，获取与用户需求相关的维度细节，最终对互联、智能、情感、易用的需求产生新的见解。我们的研究结果对未来家用冰箱的设计具有指导意义，也为其他智能家电的设计提供了指导和参考。

Work-related musculoskeletal disorders (WMSDs) seriously affect the health and well-being of oil and gas pipeline network operation and maintenance (O&M) employees. To assess the risk of WMSDs among employees in oil and gas pipeline O&M, this study constructs a systematic assessment methodology with typical job positions as the assessment object. This methodology includes identifying typical positions utilizing the Delphi method, determining the weights of risk indicators using the analytic network process, analyzing the impact consequences and possibilities of risk factors using the fuzzy comprehensive evaluation model, and evaluating the WMSD risk of each typical position combined with the risk assessment matrix. Moreover, the practicality and advantages of the methodology are verified through a case study. The results show that the method effectively assesses the WMSD risk of typical jobs in oil and gas pipeline operation and maintenance. Among the risk factors, movement and posture factors, as well as labor organization factors, had higher influence weights. Six typical jobs were identified, of which production process operators and mechanical maintenance engineers are high-risk jobs, while safety and environmental engineers have relatively low WMSD risk. Overall, this study provides an effective tool for assessing WMSD risk, thus promoting the well-being of O&M employees.

This study aims to analyze the physiological responses and task load of drivers in curved and spiral tunnels. Spiral tunnels, a unique solution for complex terrains, exhibit distinct geometric and functional characteristics compared to curved tunnels. Despite advances in spiral tunnel design in China, concerns about driver safety persist. The research recruited 30 participants to conduct naturalistic driving experiments in curved and spiral tunnels. By analyzing heart rate variability (HRV) indices and using factor analysis, four HRV indices (HR, SDNN, LF/HF, SampEn) were selected as primary indicators. Results from statistical analysis showed that drivers had a significantly higher average heart rate (HR) in spiral tunnels compared to curved tunnels (F(1,1198) = 593.29, p < 0.01), indicating greater psychological stress and physiological burden. The standard deviation of NN intervals (SDNN) was lower in spiral tunnels (F(1,1198) = 868.18, p < 0.01), suggesting reduced heart rate variability and a more dominant sympathetic tone. The ratio of low-frequency power to high-frequency power (LF/HF) was higher in spiral tunnels (F(1,1198) = 419.85, p < 0.01), indicating increased sympathetic nervous system activity. Additionally, the sample entropy (SampEn) of the electrocardiogram was lower in spiral tunnels (F(1,1198) = 1595.05, p < 0.01), suggesting a decrease in the complexity of the ECG signal and a weaker autonomic nerve regulation ability of the heart. Subjective task load evaluation using the NASA-TLX scale further revealed that drivers experienced a higher task load across various dimensions such as mental demand, physical demand, temporal demand, effort, frustration, and performance in spiral tunnels. In summary, this study provides valuable insights into the physiological and psychological responses of drivers in curved and spiral tunnels, contributing to optimizing tunnel design, improving driver education and training, and enhancing tunnel safety and the overall driving experience.

本研究旨在分析驾驶员在曲线隧道和螺旋隧道中的生理反应和任务负荷。螺旋隧道是应对复杂地形的一种独特解决方案，与曲线隧道相比，螺旋隧道具有独特的几何和功能特征。尽管中国在螺旋隧道设计方面取得了进步，但对驾驶员安全的担忧依然存在。研究招募了 30 名参与者，在弧形和螺旋形隧道中进行自然驾驶实验。通过分析心率变异性（HRV）指数，并使用因子分析，选择了四个心率变异性指数（HR、SDNN、LF/HF、SampEn）作为主要指标。统计分析结果表明，与曲线隧道相比，驾驶员在螺旋隧道中的平均心率（HR）明显更高（F(1,1198) = 593.29, p <0.01），表明心理压力和生理负担更大。螺旋形隧道的 NN 间期标准偏差（SDNN）更低（F(1,1198) = 868.18，p <0.01），表明心率变异性降低，交感神经张力更强。低频功率与高频功率之比（LF/HF）在螺旋隧道中更高（F(1,1198) = 419.85, p <0.01），表明交感神经系统活动增加。此外，螺旋隧道中心电图的样本熵（SampEn）较低（F(1,1198) = 1595.05, p <0.01），表明心电信号的复杂性降低，心脏的自律神经调节能力减弱。使用 NASA-TLX 量表进行的主观任务负荷评估进一步显示，驾驶员在精神需求、体力需求、时间需求、努力程度、挫败感和螺旋隧道中的表现等多个维度上都经历了较高的任务负荷。总之，本研究为了解驾驶员在弯道和螺旋隧道中的生理和心理反应提供了宝贵的见解，有助于优化隧道设计、改进驾驶员教育和培训、提高隧道安全性和整体驾驶体验。

Spiral tunnels, a unique solution for complex terrains, exhibit distinct geometric and functional characteristics compared to curved tunnels. Despite advances in spiral tunnel design in China, concerns about driver safety persist. The research recruited 30 participants to conduct naturalistic driving experiments in curved and spiral tunnels. By analyzing heart rate variability (HRV) indices and using factor analysis, four HRV indices (HR, SDNN, LF/HF, SampEn) were selected as primary indicators. Results from statistical analysis showed that drivers had a significantly higher average heart rate (HR) in spiral tunnels compared to curved tunnels (F(1,1198) = 593.29, p < 0.01), indicating greater psychological stress and physiological burden. The standard deviation of NN intervals (SDNN) was lower in spiral tunnels (F(1,1198) = 868.18, p < 0.01), suggesting reduced heart rate variability and a more dominant sympathetic tone. The ratio of low-frequency power to high-frequency power (LF/HF) was higher in spiral tunnels (F(1,1198) = 419.85, p < 0.01), indicating increased sympathetic nervous system activity. Additionally, the sample entropy (SampEn) of the electrocardiogram was lower in spiral tunnels (F(1,1198) = 1595.05, p < 0.01), suggesting a decrease in the complexity of the ECG signal and a weaker autonomic nerve regulation ability of the heart.

This article aimed to test the hypotheses of a complex model considering the chain relationship between occupational risk factors, work-related musculoskeletal disorders (WMSDs) symptoms, and Quality of Work Life (QWL) perceived by workers. We assessed psychosocial risk factors utilizing items from the Job Content Questionnaire, the Effort-Reward Imbalance Questionnaire, and the Copenhagen Psychosocial Questionnaire II. The biomechanical factors analyzed included poor trunk and upper limb postures, excessive lifting, and prolonged standing. Organizational factors evaluated were monotonous work, tight deadlines, and low stimulation for teamwork. Using the Nordic and Walton Questionnaires, we assessed workers’ perceptions of WMSD symptoms and QWL. We constructed the model using the Partial Least Squares Structural Equation Modeling (PLS-SEM) approach. The measurement model assessed reliability (composite reliability) and validity tests (average variance extracted, Heterotrait-Monotrait ratio of correlations method, and Fornell-Larcker criterion). The structural model analyzed direct and indirect paths between factors and tested the hypotheses (bootstrapping method). Results indicate that most biomechanical factors affect WMSDs mediated by physical work demands. Physical work demands have a direct impact on WMSDs and stress. Good psychosocial conditions alleviate stress, reduce WMSD symptoms, and increase QWL. Harmful organizational factors acted indirectly on WRMSDs, amplifying stress perception. Finally, WMSDs worsen QWL. We concluded that the model is valid with satisfactory psychometrics for measuring and relating risk factors, WMSDs, and QWL, providing insights that can guide professionals and researchers in planning and implementing actions to prevent risks and WMSD symptoms and improve QWL.

本文旨在检验一个复杂模型的假设，该模型考虑了职业风险因素、与工作相关的肌肉骨骼疾病（WMSDs）症状和工人感知的工作生活质量（QWL）之间的连锁关系。我们利用工作内容问卷、努力-回报不平衡问卷和哥本哈根社会心理问卷 II 中的项目对社会心理风险因素进行了评估。分析的生物力学因素包括躯干和上肢姿势不良、过度举重和长时间站立。评估的组织因素包括单调的工作、紧迫的截止日期和对团队合作的低刺激。我们使用北欧和沃尔顿问卷评估了工人对 WMSD 症状和 QWL 的看法。我们使用偏最小二乘法结构方程模型（PLS-SEM）方法构建了模型。测量模型评估了信度（综合信度）和效度检验（平均方差提取、异方差-单方差相关比方法和 Fornell-Larcker 标准）。结构模型分析了因子间的直接和间接路径，并对假设进行了检验（引导法）。结果表明，大多数生物力学因素对 WMSDs 的影响都以体力工作需求为中介。体力工作要求对 WMSDs 和压力有直接影响。良好的社会心理条件可减轻压力，减少 WMSD 症状，提高 QWL。有害的组织因素会间接影响 WRMSDs，放大压力感知。最后，WMSDs 会恶化 QWL。我们的结论是，该模型在测量和关联风险因素、WMSDs 和 QWL 方面具有令人满意的心理计量学效果，可以为专业人员和研究人员规划和实施预防风险和 WMSD 症状以及改善 QWL 的行动提供指导。

Exoskeletons have emerged as an opportunity for reducing work-related musculoskeletal disorders (WMSD) for industry workers. However, it is not clear how these exoskeletons will affect task or work-related performance. In this study, the effect of task height and the presence of a shoulder-support exoskeleton on sensorimotor performance was examined. Participants (n = 24) performed a sensorimotor multidirectional tapping task using a grip tool under two task heights (at shoulder, 40° above shoulder) and exoskeleton presence (present, absent). Results support that accuracy, error rate, and precision were not affected by task height and exoskeleton presence, while movement time (3.7% average movement time increase at shoulder height and 9.7% average movement time increase above shoulder height with exoskeleton presence) and throughput (3.3% average throughput decrease at shoulder height and 7.3% average throughput decrease at above shoulder height with exoskeleton presence) were affected when the exoskeleton was present. Results also support that the perceived discomfort, fatigue, and workload were influenced by task height and exoskeleton presence. This study expands understanding of the effect of a passive exoskeleton during a sensorimotor assessment task, which provides added context for industry decision-making on using exoskeletons as a method to mitigate WMSDs and motivates future design recommendations for exoskeletons.

外骨骼的出现为减少工业工人与工作相关的肌肉骨骼疾病（WMSD）提供了机会。然而，目前还不清楚这些外骨骼会如何影响任务或与工作相关的表现。本研究考察了任务高度和肩部支撑外骨骼对感知运动表现的影响。受试者（n = 24）在两种任务高度（肩部、肩部以上 40°）和外骨骼存在（存在、不存在）条件下使用抓握工具完成了一项感觉运动多向敲击任务。结果表明，准确度、错误率和精确度不受任务高度和外骨骼存在的影响，而移动时间（外骨骼存在时，肩部高度的平均移动时间增加 3.7%，肩部以上高度的平均移动时间增加 9.7%）和吞吐量（外骨骼存在时，肩部高度的平均吞吐量减少 3.3%，肩部以上高度的平均吞吐量减少 7.3%）则受到外骨骼存在的影响。研究结果还证明，任务高度和外骨骼的存在会影响感知到的不适、疲劳和工作量。这项研究加深了人们对被动式外骨骼在传感运动评估任务中的影响的理解，为行业在使用外骨骼作为减轻 WMSDs 的方法方面的决策提供了更多的背景信息，并为外骨骼的未来设计提出了建议。

Using icons from nuclear power interface as the research object, this study explored how icon similarity affected the performance of dual objective visual search. Firstly, the process of generating similarity bias was described from the perspective of human cognitive processing. The feature attributes of nuclear power icons were extracted, and then associated and mapped with similarity bias attributes. Secondly, a total of 16 instruction icons, device icons, and component icons were selected to propose icon coding logic for different similarity dimensions, and similarity experimental materials were designed. Finally, a dual objective search experiment with a 4 × 4 matrix was conducted to explore the impact of graph similarity on search performance and to determine the priority of perceptual similarity, semantic similarity, and memory similarity. High-level (H) similarity between the two targets resulted in superior visual search performance (p = 0.01 between the response times of similarity high and medium/low). Improving experiential familiarity enhanced search performance in cases of low-level (L) (p = 0.021) and medium-level (M) (p ≤ 0.009) icon similarity, but had no significant impact on search performance in cases of high-level (H) similarity (p ≥ 0.269). Compared to semantic similarity, enhancing perceptual similarity was more likely to improve search performance(p = 0.024).

本研究以核电界面的图标为研究对象，探讨了图标相似性如何影响双目标视觉搜索的表现。首先，从人类认知加工的角度描述了相似性偏差的产生过程。提取了核电图标的特征属性，然后将其与相似性偏差属性进行关联和映射。其次，选取了指令图标、设备图标和组件图标共 16 个，提出了不同相似性维度的图标编码逻辑，并设计了相似性实验材料。最后，进行了 4 × 4 矩阵的双目标搜索实验，以探索图形相似性对搜索性能的影响，并确定感知相似性、语义相似性和记忆相似性的优先级。两个目标之间的高水平（H）相似性使视觉搜索性能更优越（高相似性和中/低相似性的反应时间之间的 p = 0.01）。提高经验熟悉度可以提高低级（L）（p = 0.021）和中级（M）（p ≤ 0.009）图标相似度情况下的搜索表现，但对高级（H）相似度情况下的搜索表现没有显著影响（p ≥ 0.269）。与语义相似性相比，增强感知相似性更有可能提高搜索性能（p = 0.024）。
