A total of 24 young adults (21–29 years old) and 24 older adults (63–77 years old) participated in an experiment with two different tasks (reading and searching) on smartphones, where each task lasted 1 h. The change in critical fusion frequency (CFF) and the subjective visual fatigue score were used as physiological and subjective indices, respectively, to measure visual fatigue. The results showed that the participants experienced more severe visual fatigue in the reading task than in the searching task on smartphones. Both changes in CFF and increases in subject visual fatigue occurred earlier in the reading task than in the searching task. The participants' visual fatigue increased as the task duration increased, and physiological visual fatigue occurred significantly earlier than did subjective visual fatigue. Compared with younger adults, older adults experienced more subjective visual fatigue when the task complexity was higher and more physiological visual fatigue as task duration increased. Different arrangements of breaks should be considered according to different task types on smartphones to alleviate visual fatigue, and a short break interval every 15 min during the reading task and every 30 min during the searching task is recommended. Older adults not only need to avoid prolonged visual tasks on smartphones more but also should refrain from persisting in continuous visual work. They are in greater need of suspending visual tasks promptly as soon as they initially feel visual fatigue. In addition, designers and developers need to reduce the cognitive load brought by task complexity on smartphones to alleviate the perception of visual fatigue among older adults.</p>\u0000 </div>","PeriodicalId":55048,"journal":{"name":"Human Factors and Ergonomics in Manufacturing & Service Industries","volume":"35 3","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143831164","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

After applying a set of inclusion criteria, 367 peer-reviewed articles were included in the review. The review revealed a growth in applications of systems HFE methods over time. Overall, cognitive work analysis (CWA) was the most frequently applied, closely followed by functional resonance analysis method (FRAM) and systems theoretic accident model and process–system-theoretic process analysis (STAMP-STPA). Most applications of systems HFE methods have occurred in the Healthcare domain, and approximately one-third of the articles involved the application of multiple HFE methods, with an increasing number of these including mathematical modeling such as Systems Dynamics and Agent Based Modeling. The review suggests there is a continued demand for both qualitative and quantitative outputs in systems HFE applications. As problem spaces and system complexity continue to intensify, evaluation, and potential adaption of methods may be required, including using more than one method.

This drawback might be a source of misunderstandings and hinder the design of work systems supportive of desirable resilient performance. Two crucially distinctive manifestations refer to individual and organizational resilience. This study presents a model of how these two types relate to each other and how they relate to antecedents and consequences of resilience. To this end, we carried out a case study of freight road transport, emphasizing the truck drivers' perspectives. Data collection included 14 interviews with drivers and managers of logistics operations, in addition to non-participant observations of drivers' workplaces. Based on a thematic analysis, the model was developed consisting of seven themes: work constraints, investments, individual resilience practices, organizational resilience practices, operational efficiency, human costs, and overall costs. The first two themes are antecedents and the last three are consequences of resilience. The main relationships between the themes are presented as seven propositions for theory-testing. The model suggests three main approaches for a balanced distribution between individual and organizational resilience. These approaches consist of: tackling work constraints, especially production pressures; investing in organizational practices adopting a long-term view; and promoting individual practices that proactively support health and safety. The truck drivers' study offers examples of the applicability of these approaches.</p>\u0000 </div>","PeriodicalId":55048,"journal":{"name":"Human Factors and Ergonomics in Manufacturing & Service Industries","volume":"35 2","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143248406","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Identifying and strengthening workers' self-protection knowledge is crucial to effective heat adaptation and management. The study aimed to investigate outdoor workers' perceptions of heat-related risks, changes in protective behavior during hotter seasons, knowledge and awareness of regional heat action plans (HAPs), and protection measures. It aimed to find effective means of communication and strategies for improving heat protection among these workers. We used a validated and structured mixed-method survey questionnaire and one-on-one interviews to assess 140 outdoor workers' heat-related risk perceptions, protective behavior changes during hot seasons, and knowledge of regional HAPs protective measures in April–July 2022. The estimated worker's seasonal average WBGT exposure using meteorological data was 34.4°C ± 0.02°C, which exceeded acceptable limits. Heat was a big concern for outdoor workers, the study revealed. Workers believed that knowing about heat hazards could help reduce individual risks. Many workers were aware of the heat's health risks but felt the nature of their jobs prevented them from taking precautions. Some workers assumed that business owners' concerns about productivity and cooling costs would prevent government measures to safeguard at-risk employees from succeeding. Workers responded more positively to business owners' HAP communications. Workers are more likely to use practical, simple sector-based warning HAPs. We urgently need management policy reforms to protect millions of workers in low- and middle-income countries (LMICs), and the implementation of cost-effective, practical, and sustainable heat protection infrastructure and behavioral change solutions through trusted channels is crucial.</p>\u0000 </div>","PeriodicalId":55048,"journal":{"name":"Human Factors and Ergonomics in Manufacturing & Service Industries","volume":"35 1","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143118418","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As the complexity of tasks increases, not keeping track of all interactions may result in poor, unwanted outcomes. This research introduces a different approach to TA that decomposes tasks into their constituent functions, describes the functionality of the overall work system, traces (dynamic nonlinear) interactions among functions, and highlights the role of functional variability in forming emergent outcomes. This approach to TA is called functional task analysis (FTA). A case study on nursing work was used to demonstrate the suitability of the FTA approach. The findings of this study show that the FTA approach contributes to task modeling by building a nonsequential, nonhierarchical functional model of a complex task considering dynamic, nonlinear interactions among functions. The FTA also contributes to task description by explaining different ways a task can be accomplished. It also increases the understanding, interpretation, and analysis of how changes in work conditions shape good/acceptable and poor/unacceptable outcomes. The FTA can complement the TA by adding some aspects, including functionality, nonlinearity, dynamics, and emergence, that the TA does not normally consider.

Following Preferred Reporting of Systematic Reviews and Meta-Analysis guidelines, a meticulous search of Scopus and PubMed from August 2022 to March 2023 yielded 34 articles, with 26 focusing on biomechanical effects and eight on comfort effects. The studies, conducted during static and dynamic activities, such as standing, walking, jogging, running, jumping, and cycling, reveal significant reductions in rearfoot eversion, knee joint forces, and lower extremity muscle forces through postings and wedging in FOs. Changes in stiffness impact rearfoot kinematics, plantar pressure distribution, and ankle–foot power distribution. Conversely, surface texture and arch variations demonstrate limited significance. FOs and shoe inserts, characterized by geometric, material, location, size, and fabrication features, effectively regulate forces and moments on the lower extremity. This control promotes uniform plantar pressure distribution and enhances comfort during various activities.

Given that human error probability (HEP) is influenced by various common performance conditions (CPCs) and their sub-factors, and changes dynamically in response to other variables, the SD method offers a practical approach for estimating and predicting human error behavior over time. This study identifies and quantifies the variables affecting HEP, explores their interactions and feedback in maintenance tasks, and assesses the associated costs. The machine learning technique is then used to estimate the relationship between HEP and these costs. The optimal value of the HEP function, 0.000772, is determined by identifying the minimum point of a cubic function, thereby minimizing associated costs and occupational accidents. Determining the optimal HEP is crucial for minimizing excessive costs and investing in improved ergonomics and CPCs for better performance. This addresses a significant gap in existing research where the impact of human error on maintenance tasks has not been estimated as a function.
