Overcoming COVID-19 pandemic: emerging challenges of human factors and the role of cognitive ergonomics

The present study, an expert review, aimed to discuss the emerging challenges of overcoming COVID-19 from the perspective of human factors and the importance of cognitive ergonomics in helping to cope with the epidemic. Identifying these challenges and the use of cognitive ergonomics to optimize human well-being and system performance can be effective in managing COVID-19. Generally, two main preventive approaches such as social distancing and patient care or treatment approaches are being utilized in response to COVID-19. In this paper, human factors challenges that could emerge from covid-19 preventive approaches were discussed. Social distancing forces presence and increases automated systems that lead to increases in cognitive needs, mental workload, stress, etc. Challenges of treatment and health care include the increased workload of healthcare personnel, stress, changing work systems and task allocation that led to fatigue and stress, threats to patient safety, and disruption of interpersonal interactions from a cognitive ergonomic perspective. It is concluded that the challenges of coping with COVID-19 were numerous and important from the perspective of human factors and the role of cognitive ergonomics is important in controlling the disease;hence, it should be taken into consideration.

Everybody hurts - What can physical health professionals learn about how mental health professionals support their own emotional resilience and mental health?

The physical aspects of ultrasonography, difficult posture with prolonged pressure exertion, have been extensively researched and addressed with advances in machine ergonomics, operator awareness of posture and positioning and workplace tools to identify musculoskeletal problems. The mental stresses are less well recognized and have only recently started getting investigated. Ultrasonography is a mentally challenging activity requiring long periods of intense concentration, empathy and communication of complex and often difficult information to patients and clinicians, all of which carries an emotional toll. Practitioners are also under increasing time and caseload pressures exacerbated by COVID recovery and chronic fatigue from two years of pandemic. A survey of UK obstetric sonographers showed 92.1% and 91.0% met the burnout thresholds for exhaustion and disengagement, respectively).1 While many Trusts provide training to support physical health, few radiology departments educate their staff on emotional resilience or offer regular support to either promote or maintain mental wellbeing. Training, when available, is often focused on the receiver and not on the impact of vicarious traumas experienced as a result of repeatedly discovering/delivering difficult outcomes to patients on a regular and prolonged basis. Few health professionals are face-to-face with their patient at point of significant discovery whether that information is imparted to the patient or not. Mental health professionals have adopted a traumainformed stance into their working practices. This has not only informed the direct clinical work with patients but is also evident in the way the workforce is supported by the trust. Regular supervision, reflective practice and debriefs are required and monitored by the trust, based on research in clinical psychology to inform best practice. Some of these practices could be applied to physical health professionals to address some of the emotional burdens experienced as part of day-to-day delivery of care.

Ergonomics in online education of medical undergraduates: A challenge to post-COVID transformation in educational activities.

BACKGROUND: Practicing incorrect postures in online and virtual education during the COVID-19 pandemic can cause significant study-related musculoskeletal problems among students. OBJECTIVE: This study evaluated the knowledge, attitude, and practice of sitting posture and computer ergonomics and study-related musculoskeletal problems in undergraduates who followed online education during the pandemic. METHODS: A cross-sectional online survey among a cohort of Sri Lankan medical undergraduates was conducted using a structured questionnaire with 56 multiple-choice or Yes/No type questions. RESULTS: Of the 410 participants, over 85% (n = 362) knew the correct posture to sit on the chair type that they frequently used for studies. However, the majority (n = 378,92.20%) practised incorrect sitting postures in which leaning forward (n = 319,77.80%) was the most common suboptimal posture. Knowledge (n = 161,40%) and practice (n = 167,40.73%) on taking frequent breaks were poor among the majority. Their knowledge on computer ergonomics was good (>80%, n = 304) except for the recommended eye-to-screen distance (n = 129,31.46%). Importantly, ∼50% (n = 206) did not practise the recommended eye-to-screen distance. Use of non-adjustable chairs with no armrests (n = 346,84.39%) and smartphones (n = 354,86.34%) were identified as the main factors which hindered correct practices. Study-related pain/discomfort reported by the majority (n = 241,58.78%) is potentially due to suboptimal ergonomics. Their attitude toward learning and practicing correct ergonomics in home workstations was good (n = 383,93.41%). CONCLUSION: Poor practice of posture and computer ergonomics, despite the good knowledge and attitude is possibly due to the suboptimal work environments. Introducing simple practical measures to facilitate ergonomically appropriate work environments is mandatory in virtual education to prevent study-related musculoskeletal problems.

Safer surgical practice: a guide for surgeons (not just for pandemics)

The surgical working environment has changed considerably since the World Health Organisation (WHO) declared the coronavirus outbreak, COVID-19 (SARS-CoV-2), a pandemic on 11 March 2020. Measures remain in place to reduce the risk of spread from patients to surgeons, nosocomial infection and amongst healthcare workers. However, despite these protective measures, healthcare staff are at risk with the number of health workforce deaths increasing worldwide. This article sets out to explore the roles and responsibilities of the surgeon during these extraordinary times and discuss how we can improve our practice to reduce the risk of harm to patients, surgical staff, and ourselves.

Instructional Usability and Learner-User eXperience Assessment in a Virtual Reality Educational Milieu: A Deductive Tech-Instructionality Model from EdTech

Educational Technology (EdTech) lacks a foundational, formal, scientific, epistemic theory. Therefore, it lacks native constructs/variables and an epistemological object of study for scientifically deploying its work. This study determines the existence (ontology) of the theorized constructs Instructional Usability (UsI) and Learner-User eXperience (LUX) and defines their characterization (epistemology). Both constructs were modeled and instrumented. Furthermore, a Tech-Instructionality Model (TIM) was theorized and developed in this paper, both analytically and empirically. The model integrates UsI and LUX as two pairs of constructs linked with two EdTech epistemological objects of study, the instructional interface and the instructional interaction in two assessment modalities, testing mode (user-learner view) and inspection mode (expert/designer view). Two instruments were developed and validated in this study for testing mode, the Instructional Usability Scale (SUsI) and the Learner-User eXperience Questionnaire (QLUX). Both instruments were tested in a non-immersive virtual reality educational milieu during the academic lockdown of the Covid19 pandemic. The results show that both SUsI and QLUX consistently measured UsI and LUX, thus, providing a valid assessment for tech-instructionality and a foundation for constructing a scientific theory of EdTech. © 2023 IEEE.

Assessment of selected psychosocial risk factors: stress, job burnout, and bullying in the case of medical staff as part of workplace ergonomics during the COVID-19 pandemic-A prospective pilot study.

Background: The purpose of the pilot study conducted by the authors was to assess occupational risk in selected areas of psychosocial risk factors among health professions in a pilot study. Medical staff working in the healthcare sector experience stress, job burnout and bullying on a daily basis. Monitoring occupational risks in the above areas provides an opportunity to take appropriate preventive measures. Methods: The prospective online survey included 143 health care workers from various professional groups. Eighteen participants did not complete the survey, and the results of 125 participants were eventually included in the analysis. The study used health and safety questionnaires in the healthcare sector, which are not widely used as screening tools in Poland. Results: The following statistical methods were performed in the study: the Mann-Whitney test, Kruskal-Wallis test, Dunn's test. In addition, multivariate analysis was performed. The results obtained in the study indicate that the questionnaires used in the study can be widely used by employers or occupational medicine as screening tools. Conclusions: Our findings show that level of education attainment in healthcare is correlated with higher chance of experiencing stress and burnout. Among the surveyed professions, nurses reported a higher amount of stress and burnout. Paramedics reported the highest chance of being bullied at work. This can be explained by their nature of work which requires directly interacting with patients and their families. In addition, it should be noted that the tools used can be successfully applied in workplaces as elements of workplace ergonomics assessment in the context of cognitive ergonomics.

A Multi-component Intervention (NEXpro) Reduces Neck Pain-Related Work Productivity Loss: A Randomized Controlled Trial Among Swiss Office Workers.

Purpose Neck pain is common among office workers and leads to work productivity loss. This study aimed to investigate the effect of a multi-component intervention on neck pain-related work productivity loss among Swiss office workers. Methods Office workers, aged 18-65 years, and without serious neck-related health problems were recruited from two organisations for our stepped-wedge cluster randomized controlled trial. The 12-week multi-component intervention included neck exercises, health-promotion information, and workplace ergonomics. The primary outcome of neck pain-related work productivity loss was measured using the Work Productivity and Activity Impairment Questionnaire and expressed as percentages of working time. In addition, we reported the weekly monetary value of neck pain-related work productivity loss. Data was analysed on an intention-to-treat basis using a generalized linear mixed-effects model. Results Data from 120 participants were analysed with 517 observations. At baseline, the mean age was 43.7 years (SD 9.8 years), 71.7% of participants were female (N = 86), about 80% (N = 95) reported mild to moderate neck pain, and neck pain-related work productivity loss was 12% of working time (absenteeism: 1.2%, presenteeism: 10.8%). We found an effect of our multi-component intervention on neck pain-related work productivity loss, with a marginal predicted mean reduction of 2.8 percentage points (b = -0.27; 95% CI: -0.54 to -0.001, p = 0.049). Weekly saved costs were Swiss Francs 27.40 per participant. Conclusions: Our study provides evidence for the effectiveness of a multi-component intervention to reduce neck pain-related work productivity loss with implications for employers, employees, and policy makers.Trial Registration ClinicalTrials.gov, NCT04169646.

Effects of Critical Components of Home Office on Ergonomics of Workers during COVID-19 Pandemic

Background: The COVID-19 has impacted our education system in various ways and to compensate the losses, teachers had to make quick transition from face to face teaching to online mode of teaching. This unexpected transition has entailed challenges and constraints for the health all of us. Objective: To find the effect of critical components of home-office on the ergonomics of workers. Study type, settings and duration: This cross sectional survey was conducted at Riphah International University (all departments), Lahore Grammar School, Lahore and Minhaj University, Lahore from March to June 2020. Methodology: This was a cross sectional survey on computer workers and faculty from educational setups such as university centers in an attempt to determine the effects of critical components of home-office on the ergonomics of the workers. The sample size was calculated to N=80. As per inclusion criteria, workers and members of faculty working on computers from Lahore, had worked from home-office during the lock down for consistent 4 months and the working should be synchronous, were included in this study. REBA questionnaire was used to collect data from the workers in person. Frequencies and percentages were calculated to find the impact of home-office components on the ergonomics of the workers. Results: The study found that 57% of computer workers between 26-30 years had a high risk index for poor ergonomics, with moderate changes in 71.3% of the population. The REBA score represents MSD risk for the job task and the design goal is 4. Conclusion: From this study it was concluded that nearly 70% of the population was having an ergonomically poor posture while working. In addition to that, in nearly half of the population the risk was significant.

Design of Workstation for Remote Workers with Work Environment Consideration

The COVID-19 pandemic that began in 2020 has caused various phenomena in some fields of work, especially the phenomenon of remote working. The phenomenon of remote working is possible through the advancement of information and communication technology (ICT). The good impact on the environment, especially air pollution decreasing due to the lack of commuting, makes the phenomenon of remote working need to be enhanced so that the positive impact on the environment increases. This exploratory research found that the work environment factors in the workstation design, including physical ergonomics, lighting, noise, etc., greatly affect the productivity of remote workers. This workstation design is a solution for remote workers during and post-pandemic.

Exploring Consumers' Intention to Use Bikes and E-Scooters during the COVID-19 Pandemic in the Philippines: An Extended Theory of Planned Behavior Approach with a Consideration of Pro-Environmental Identity

The onset of the COVID-19 pandemic has prompted nations globally to adopt lockdown policies, resulting in a substantial shift in people's travel behavior. This pandemic has influenced micro-mobility, an emerging urban transportation mode, including in the Philippines. However, a limited quantifiable study is dedicated to understanding the evolving micro-mobility use in response to the COVID-19 pandemic. This study aims to determine the impacts of the COVID-19 pandemic on our future intention to use micro-mobility, particularly e-scooters/bikes, and to explore how hedonic and environmental motivations influence the decision-making process of its adoption. An extended Theory of Planned Behavior (TPB) was employed, with 152 Filipinos answering an online questionnaire that was distributed using a convenience sampling approach. Structural Equation Modeling (SEM) showed that the COVID-19 pandemic emphasized the awareness of environmental issues and the negative impact of cars, thereby significantly influencing the usage intention of e-scooters/bikes. In addition, social norms and perceived behavioral control partially mediated the relationship between the COVID-19 pandemic and the intention to use micro-mobility. Meanwhile, the magnitude and significance of motivation variables were inconclusive, although they confirmed a positive relationship with attitude. The findings of this study could help provider firms and policymakers devise evidence-based policies concerning micro-mobility and promote its usage, particularly in developing countries.

Ergonomics-oriented operation, maintenance and control of indoor air environment for public buildings

In response to the construction process of Healthy China. it is rather important to create a safe, healthy and energy-efficient indoor environment for public buildings. The public building space is often densely populated, with a large flow of people and many types of air pollution, which presents non-uniform dynamic distribution characteristics. This brings great challenges to the control of indoor air safety, especially during the pandemic period of COVID-19. Excessive ventilation may not only cause large energy waste. but also lead to cross-contamination and even a cluster of infection. In this paper, an operation and maintenance (O&M) control system for indoor air safety is developed based on the core concepts and basic methods of human ergonomics. In this system, one of the important human environmental variables is focused for control, i.e.. indoor air pollution level. Especially after the outbreak of COVID-19. droplets and droplet nuclei from respiration are the most significant air pollution categories required for mitigation. Towards the efficient control of air pollution in large public buildings. it should further take into account the interaction of human, equipment and machines (i.e., ventilation_ air purification and disinfection and intelligent control system) and building environment. Firstly, on the basis of the online monitoring of indoor air pollution concentration and personnel flow, the non-uniform dynamic distribution of indoor pollutants and personnel can be obtained by using the non-uniform and low-dimensional rapid prediction models and computer vision processing. Then, the optimal setting results of ventilation parameters (e.g., ventilation modes, supply air rate. etc.) can be outputted by the environmental control decision system. Finally, based on a combination of monitoring sensors, controllers and actuator hardware equipment (at the location of fans or dampers), the intelligent regulation and control of ventilation system can be realized, aimed at minimizing energy consumption and reducing pollutant concentration and exposure level. Meanwhile, the air purification and disinfection system (especially for the disinfection of virus particles) are operated under the condition of the ventilated environment, which can serve as a powerful auxiliary to the maintenance of indoor air safety. The workflow and effect of the O&M control system are demonstrated by an engineering application case of the front hall in the International Convention and Exhibition Center. The results indicate that the non-uniform and low-dimensional rapid prediction model for pollutant concentration is effective for the ventilation control with the average prediction difference of 11.9%. The implementation of the intelligent ventilation system can reduce the risk of human infection to less than 4%. and its energy-saving ratio for the ventilation can be as high as about 45%. Through optimizing the layout strategies of disinfection devices based on the intelligent ventilation control, the space accessibility of negative oxygen ions can be well accepted, to further increase the removal efficiency of air pollution. The calculated value of space disinfection rate is more than 99%, which can further reduce the risk of infection by 1-2 orders of magnitude. This study can provide an important reference for the promotion and upgrading of O&M control system for indoor air safety.

Ergonomics in "Remote Work" Activities: A Workstation Adaptation Case Study in Brazil

The coronavirus disease 2019 (COVID-19) pandemic decreed by the outbreak of the new coronavirus culminated in the need to implement jobs in the homes of employees who had to adhere to the "remote work" style, due to social isolation actions in Brazil. Many of the employees started to work in the absence of adequate working conditions in their homes, impacting the three dimensions of ergonomics, i.e., physical, organizational and cognitive. The objective of this chapter is to report the adjustments made in a workplace after the change of modality from face-to-face (f2f) activities to "remote work" after the beginning of the pandemic in 2020, aiming to adopt actions aimed at ergonomics. The research was carried out with a professional in the area of Environmental and Sanitary Engineering who started remote work in March 2020. The work is of a qualitative nature, using photos to illustrate the changes occurring before and after the installation of the equipments and reports on strategies to improve working conditions in the "remote work". The cost of physical adaptations was also computed. The most reported complaints collected by the professional were back pain, neck, forearm, wrist and eye pain, in addition to mental fatigue. The necessary equipment and furniture were acquired for the physical adaptation of the workspace. Issues of working hours, days off, means of communication were also addressed, but aspects of cognitive and organizational ergonomics must have the participation of the entire work group to achieve effective results. The accompaniment of a specialized technical professional would be important for the establishment of further assertive actions, seeking the productivity and quality of life of the employee.

Professional practices at the heart of the crisis in emergency management: The example of the COVID-19 crisis

Our organisations have been severely shaken by the COVID-19 pandemic and the world of work has not been spared. Only essential activities continued in order to maintain a minimum level of functioning, just like in hospitals or in local authorities. During the first five months of the crisis in 2020 (from March to July), 34 interviews were conducted in these two public service entities in order to examine the management of urgent matters in the light of ``activity'' and at the heart of the crisis. The results show that while the emergency is mainly managed by an improvisation activity based on the intuition of the actors in the field, the crisis is managed by governance in a rational manner leading to the drafting of procedures after the event. This crisis situation pushed organisations to reconfigure themselves in an emergency, allowing the development of new professional practices. The strategies of damage control and proceduralization will be discussed. Perspectives are opened on the questions of training for these crisis situations against a background of developing presumption of ignorance. (c) 2022 AIPTLF. Published by Elsevier Masson SAS.

Evaluation of Musculoskeletal Disorders and the Effect of Ergonomic Conditions in Karadeniz Technical University Students Receiving Distance Education Due to COVID-19

Objective: The aim of the study was to evaluate the effects of musculoskeletal disorders (MSDs) and ergonomic conditions in Karadeniz Technical University students who received distance education due to coronavirus disease-2019 (COVID-19). Methods: The population of this descriptive study consisted of 33,219 students at Karadeniz Technical University. Three hundred two university students selected using the convenience sampling method were included in the study by completing the questionnaire completely. Participation in the research was based on volunteering. The questionnaire consisted of sociodemographic and personal characteristics, online education and work environment characteristics, Cornell Musculoskeletal Disorders Questionnaire and International Physical Activity Questionnaire Short Form. Results: The mean of participants' Total Cornell Score was 76.6 +/- 97.3 (0-624). The chairs used by 205 (67.9%) of the participants during the lesson did not have wheels and 360 degrees rotation feature. Total Cornell Score of the participants without head-neck and lumbar support was statistically significantly higher than those with head-neck and lumbar support (p values were 0.009 and 0.006, respectively). The Total Cornell Score was statistically significantly higher in the participants who could not put their feet on the ground completely while sitting on the chair compared to the participants who could keep their feet on the ground completely (p=0.018). The Total Cornell Score was statistically significantly lower in those who had adequate lighting in the room used during the lesson than those who did not have (p=0.028). Conclusion: This study showed the importance of providing ergonomically appropriate conditions in the working environment in order to prevent musculoskeletal disorders.

Management Processes at Software Level to Enhance Intelligent Vehicles Ergonomics

The software development process is at the heart of intelligent vehicles (connected and autonomous vehicles), and it must be managed with diligence. The development of automaticity and connectivity is carried out through functional safety and, respectively, cybersecurity development processes, guided by standards that describe procedures, best practices, hazards, threats, and management strategies. By improving the software development process, the ergonomics of the intelligent vehicles will be increased. This paper presents the way on how to manage the process of achieving automaticity and connectivity through software development and if the COVID-19 pandemic could altered the management team strategy and software development process.

Quality is more important than quantity: Social presence and workplace ergonomics control predict perceived remote work performance

The Covid-19 pandemic has caused a widespread disruption to the way that we work. One of its lasting consequences will be the ubiquity of remote work. The effective use of collaboration tools is therefore a critical factor for information systems (IS) research when design the workplaces of the future. We theorize that social presence and workplace ergonomics control are important predictors of perceived performance. Moreover, we investigate how different factors (i.e., collaboration tool efficacy, mode of work, and number of meetings) influence social presence. Using survey data (N = 389), we provide evidence that workplace ergonomics control and social presence are indeed important for perceived performance. Surprisingly, we observe that only collaborative platform efficacy has a significant impact on social presence, and that neither the number of meetings nor the modality were significant factors. Based upon these results, we derive implications for theory and practice. © 2023 IEEE Computer Society. All rights reserved.

A study on changing student opinion on e-learning in the pandemic period

COVÍD-19 salgını dünya çapında her kuruluşu ve yaşamın her yönünü etkiledi. Pandemi, neredeyse tüm üniversitelerin geleneksel yüz yüze sınıftan e-öğrenme eğitimine geçmek zorunda kalmasıyla akademik kurumlar arasında beklenmedik bir kafa karışıklığına neden oldu. Üniversiteler, faaliyetlerini sürdürmek için ileri teknolojilerden yararlanmaya başladılar. Bu araştırmanın amacı, mühendislik öğrencilerin e-öğrenmeye ilişkin değişen tutumlarını izlemektir. Araştırma Ístanbul Maltepe Üniversitesi'nde öğrenim gören 408 kişilik bir mühendislik öğrenci grubu ile gerçekleştirilmiştir. Sonuçlar, salgın döneminin uzaması nedeniyle öğrencilerin e-öğrenmeye yönelik tutumlarının önemli ölçüde değiştiğini göstermiştir. Bu çalışma, son çalışmaların sonuçlarıyla tutarlı olarak düşüş eğilimini doğrulamıştır. Çalışmanın sonuçları, öğrencilerin çevrimiçi öğrenme yerine yüz yüze eğitim veya hibrit eğitim modelini tercih ettiğini göstermiştir. Bu değişen kararda sosyal izolasyon, karşılaşılan teknik sorunlar ve evde eğitimin yetersiz ve eğitmenlerle etkileşime geçme imkanının kısıtlı olması önemli rol oynamıştır. Bu çalışma ileride çeşitli nedenlerle meydana gelebilecek olası kapanmalarda reaksiyon süresini azaltabilir.Alternate : The COVID‐19 pandemic has affected every organization and every aspect of life worldwide. The pandemic has caused unexpected confusion across academic institutions, with almost all universities forced to shift from traditional face-to-face classrooms to e-learning education. Universities have leveraged advanced technologies to continue their activities, with recent technologies increasing learning effectiveness. This research aims to track the changing opinion of engineering students on e-learning applications. The research was conducted with 408 Maltepe University, Istanbul, Turkey engineering students. The results showed that engineering students' opinions had changed dramatically toward e-learning due to the prolongation of the epidemic period. This study confirmed the downward trend, consistent with the outcomes of recent studies. Furthermore, the study results showed that students prefer face-to-face or hybrid education to online learning. Social isolation, technical problems encountered, and inefficient education at home with limited opportunity to interact with the instructors play an important role in this changing decision. This study also may guide and decrease the response time on possible shutdowns that may occur in the future due to various reasons.

Survey of occupational risks in the agricultural sector of northeastern Buenos Aires, Argentina

Due to the scarce antecedents and the need to contribute to professional training, the following objectives were proposed: To study occupational hazards in the agricultural sector of the northeast of the province of Buenos Aires. To train students of the career of Higher Technician in Occupational Hygiene and Safety in the Workplace to carry out an investigation. A survey was carried out with 104 people of the local agricultural sector, during 2021 under the different modalities allowed by the coronavirus pandemics. The main risks surveyed were those related to the use of tractors and agricultural machinery, the use of agrochemicals, overexertion and exposure to climatic factors. A diversity of chemical products used was observed, which is directly related to the diversity of agricultural activities in the area. Training was scarce, with INTA being the main institution that carries out training in the region. The coronavirus pandemics had little impact on the activity, mainly in terms of less sales, difficulty in working according to protocols and loss of wages. There was agreement on the need for greater training and control by the authorities in terms of hygiene, safety and ergonomics in the field of agricultural work. With respect to the pedagogical objective sought, the research enabled the students to be trained for their future professional life. © 2022, Asociacion Argentina de Horticultura - ASAHO.
