Full textAbstract:
Purpose – The purpose of this paper is to explore the value of utilising a holistic ergonomic approach, covering engineering, cognitive and social perspectives, to cultivate beneficial and productive collaborative information seeking (CIS) systems and environments, specifically with regard to three main CIS pillars (control, communication and awareness). Design/methodology/approach – A qualitative research approach, based on a selective corpus of CIS literature, was utilised to perform a content analysis to note if terms and concepts normally associated with engineering, cognitive and social ergonomics can be used to eliminate terms reflecting issues related to three CIS pillars (control, communication and awareness) that can benefit from a holistic ergonomic approach. Findings – The content analysis revealed that a fairly extensive amount of holistic ergonomic terminology is prominent within the CIS literature, therefore establishing a connection between the two disciplines: CIS and ergonomics. This suggests that CIS system issues could benefit from the insights of a holistic ergonomic approach. Research limitations/implications – Since this is an exploratory study the scope of CIS literature utilised in the content analysis was limited to a selection considered most important by the authors; this should be supplemented by further research. Practical implications – Intended to instigate interest in further exploration of the beneficial and productive implications and practical application of holistic ergonomics in designing CIS systems and environments. Originality/value – This is the first research paper in the Library and Information Science literature that explores the potential of utilising holistic ergonomics to cultivate CIS systems and environments.

In ergonomics, handgrip has been perceived as one of the most important hand functions; however, other types of functions of the hand are also important to the ergonomist, such as finger and manual dexterity, on which few ergonomic studies have been done. This experiment involved 60 male and female college students whose performance (number of pegs placed into a board in 30 sec.) of finger dexterity were statistically significantly different between the right and left hands and between women and men. The interaction of hand and sex was significant.

AbstractChristiansen & Chater (C&C) have taken the interactionist approach to linguistic universals to an extreme, adopting the metaphor of language as an organism. This metaphor adds no insights to five decades of analyzing language universals as the result of interaction of linguistically unique and general cognitive systems. This metaphor is also based on an outmoded view of classical Darwinian evolution and has no clear basis in biology or cognition.

Aim: Implement ergonomic process improvement within the OR, to decrease incidence of injuries from sharps and needle sticks among the OR teams. Method: A pre and post intervention design was adopted. The number of reported incidents related to needle sticks and sharps over a seven month period prior to the implementation of the ergonomic process improvement(January to July 2014) and over a seven month period following implementation(January to July 2015), were compared. A participatory approach was adopted, for conducting the study and the study team included an ergonomist, surgery educators, two surgeons, operations leader, department manager, team lead, risk manager and two pre-med students functioning as study assistants. Ergonomics training for the prevention of injuries from sharps and needle sticks was developed, which incorporated physical, cognitive and teamwork measures alongside the prevention measures outlined by AORN and evidence based measures identified following a literature review. The Surgery Educator, the Ergonomist and an Attending Surgeon, participated in delivering the ergonomics injury prevention training. The management, including the Team Lead and OR Manager participated in supporting and facilitating the implementation of the injury prevention measures, where possible, such as double gloving; safe passing zones; verbal feedback; silence or task related communications only during critical phases, etc. Results: A significant difference was found in the frequency of the overall sharps and needle stick related incidents over the pre and post implementation time periods of interest(Wilcoxon Signed Rank test - significant at p≤ 0.05 level, where the W-value is 2 and the critical value for W with N=6 is 2). 63.51% decrease in incidence rate was found among the OR staff, and 44.25% decrease in incidence rate was found among students and residents, pre and post implementation. Overall, a 55% decrease was found in the incident rate of events related to sharps and needle sticks among the OR teams(experts and novices combined), over the first seven months of implementing the ergonomic process improvement. Conclusion Within the complex task and team work environments of the operating room in teaching hospitals, ergonomics and human factors fundamentals related to individual task performance, team work and work design could help improve the effectiveness of the safety measures.

Existem trabalhos que causam mais desgastes físicos e psíquicos, alguns fatores como a falta de interação social no trabalho entre colegas e chefes, jornadas de trabalhos longas sem interrupções, mobílias inadequadas aos trabalhadores e exigência cognitiva também aumentam a chance de danos à saúde. Durante a jornada de trabalho ocorrem modificações e adaptações no corpo dos trabalhadores devido à carga de trabalho física, cognitiva e organizacional. A carga física causa a fadiga de órgãos e músculos, a cognitiva causa a fadiga psicológica, a organizacional, em virtude ao processo de trabalho, causa estresse. Desta forma, a ergonomia irá abordar durante a análise da atividade estes três fatores, que podem ser risco de adoecimento, quando inadequados e em sobrecarga. Esta pesquisa teve como objetivo realizar uma análise ergonômica, por meio de entrevistas aos coordenadores dos cursos da área da saúde e propor melhorias. Como metodologia foi realizada uma AET, com coletas de informações a respeito da tarefa e atividade, para verificação da presença de dores, bem como o local e a intensidade, e foi utilizado o questionário bipolar ISO 20646, para complementar foi utilizada a ferramenta de avaliação Ergonomic Workplace Analysis (EWA). Como resultados foi possível verificar, pelo questionário NASA, que existe exigência mental e temporal, porém são características da atividade desempenhada e existem períodos de maior demanda cognitiva. Foi possível elencar os aspectos físicos, que necessitam de melhorias para adaptar o posto de trabalho ao trabalhador; além de compreender e propor melhorias que visem enquadrar na NR 17, enfatizando o conforto, segurança e eficácia da atividade prestada.Palavras-chave: Engenharia Humana. Fisioterapia. Saúde do Trabalhador.AbstractThere are jobs that cause more physical and psychological wear, factors such as lack of social interaction at work between colleagues and bosses, long hours of uninterrupted work, inadequate furniture and cognitive requirements also increase the chance of health damage. During the working day there are changes and adaptations in the workers’ body due to the physical, cognitive and organizational workload. The physical burden causes organs and muscles’ fatigue, just as the cognitive causes psychological fatigue, the organizational because due to the work process, causes stress. Therefore, ergonomics will approach during the activity analysis thesethree factors that can be risk of becoming ill, when inadequate and in excess. This research had as objective to perform an ergonomic analysis through interviews to the health area coordinators and propose improvements. As a methodology, an AET was carried out, with data collection about the task and activity, to verify the presence of pain, as well as the location and intensity, using the ISO 20646 bipolar questionnaire, to complement the evaluation tool Ergonomic Workplace Analysis (EWA). As results it was possible to verify through the NASA questionnaire that there is a mental and temporal requirement, but they are characteristics of the activity performed and there are periods of greater cognitive demand. It was possible to list the physical aspects that need improvement to adapt the work station to the worker, besides understanding and proposing improvements that aim to fit in the NR 17, emphasizing the comfort, safety and effectiveness of the activity provided.Keywords: Human Engineering.

Full textAbstract:
Nowadays, the ergonomic issues become more and more important in all economic activity domains. Work-related Musculoskeletal Disorders (MSDs) represent the main problem generated by the poor ergonomic design of the workplaces. The healthcare domain involves high level ergonomic risks related to physical and mental load of the work which could lead to MSDs. The paper presents an analysis of these ergonomic risks for physiotherapy activity and identifies potential measures to improve the health and safety in this domain. The physical load of the physiotherapist’s work is generated by the risk factors such as awkward postures, repetitive movement or working with patients with motor disabilities. The mental load of the physiotherapist’s work depends on risk factors such as working with patients with cognitive impairment and daily or weekly patient flows. The proposed preventive measures are organisational and technical. The organisational measures are based on the requirements of the occupational health and safety (OHS) legislation and on the good practice examples. The technical measures are based on the analysing the documentation of physiotherapy modern equipment. The results of the study can be used to improve the ergonomics and the health and safety of any workplace in physiotherapy activity.

Full textAbstract:
In recent years, there has been a trend toward automation and data exchange in manufacturing processes through industrial cognitive computing, the Internet of Things (IoT), and artificial intelligence. However, the human–machine interface plays a role in establishing a smart manufacturing system in any industry. It is necessary to develop a comprehensive model to identify the risk factors that contribute to the loss of human performance and productivity and evaluate the workplace for its compliance and agility toward safe human–machine systems. In this study, a model is proposed that can be used as a measurement tool to design ergonomic workplaces in the automotive industry. Several criteria have been classified under four enablers: physiological factors, psychological factors, environmental factors, and safety factors. These were identified through a literature review. The proposed model integrates the applications of structural equation modeling (SEM), interpretive structural modeling (ISM), and the multigrade fuzzy approach. ISM was employed to demonstrate the applicability of the model to depict various ergonomic enablers considered in the ergonomic measurement. SEM was used to validate the ergonomic measurement model statistically. Physiological factors were found to be highly correlated with ergonomic practices. Physiological and psychological factors were also highly correlated. The use of the multigrade fuzzy approach was demonstrated to determine the human factor index for an automotive component manufacturing industry. The proposed model can enable management to evaluate the various risk factors that hamper the ergonomic level of a company and thereby allow the company to harness the benefits of ergonomics to enhance safety and productivity.

The term “ergonomics” means practical learning which determines the conditions for the optimal adjustment of tools, equipment, technology and organizational structures to meet the needs of employees. In an age of scientific-technological progress systematic research on human work supported by technology is indispensable. Technical civilization is not the “non-humanistic” world. Its creators enter into ethical relationships with recipients. The process of work humanization must be considered on three cognitive levels: theoretical, axiological and practical. This approach is neither contradictory nor competitive to the traditional understanding of ergonomic tasks, but is complementary to it. It is significant as it teaches how to use the achievements of knowledge wisely to facilitate and take human life to a higher level, also in moral terms.

Typhoon Rai (202122) was one of the most devastating natural disasters globally, and the Philippines is the country that was heavily hit by this super typhoon. This study examined the preparedness of Filipinos using a novel framework considering ergonomic domains and disaster knowledge. A total of 414 Filipinos in eight regions affected by the typhoon answered the online questionnaire distributed through social media sites using a convenience sampling approach. Ergonomic-based indicators for physical, cognitive, and macro-ergonomics were analyzed simultaneously with disaster-knowledge indicators such as awareness, adaptation, and risk perception. The results from the partial least square structural equation modeling (PLS-SEM) and artificial neural network (ANN) showed that physical ergonomics and macro-ergonomics are key factors affecting the perceived preparedness of Filipinos for Typhoon Rai (202122). Moreover, disaster awareness, adaptation, and risk perception were also found to positively influence the respondents’ perceived preparedness, while disaster awareness influenced adaptation and risk perception. The findings revealed that residents in highly exposed locations must practice typhoon preparation and evacuation ahead of time. The results of this study could be utilized to educate local communities about the importance of emergency response options during a typhoon to lessen the damage and risks associated with it. Academicians and disaster planners may extend the findings of this study to investigate the role of ergonomics and disaster knowledge in developing preparedness systems to increase resilience by strengthening emergency management knowledge, reinforcing coordination, and communication among communities, decreasing occupational dangers, and improving processes to improve response efficiency and effectiveness.

Full textAbstract:
The ergonomic reliability assessment of interface design scheme for the passenger car is very practical to enhance driving safety performance. In addition, it can significantly reduce development costs and the development cycle of the new car. From the perspective of guiding the improvement of the central console interactive interface design of the passenger car, the most effective method to build the ergonomic reliability assessment method of the interactive interface is to evaluate and predict the human reliability objectively and subjectively and to design, feedback, and guide the design process of the ergonomic interface for the passenger car. Firstly, the questionnaire survey and the classification of ergonomic reliability analysis factors are analyzed to be put forward based on predecessors; the judgment layer factors and index layer factors of human-machine interaction interface in automobile central console are put forward. Secondly, entropy weight method (EWM) and multiple attribute decision-making (MADM) were used for objective evaluation and subjective evaluation, respectively. Thirdly, the interaction interfaces in central consoles of three different passenger cars are taken as examples; objective simulated experimental test based on entropy weight method and subjective scoring evaluation based on MADM were conducted, respectively. Besides, the objective evaluation and subjective evaluation are coupled by fuzzy comprehensive evaluation. Finally, to verify the effectiveness and rationality of the ergonomic reliability assessment method, human cognitive reliability experiments are made based on the data acquisition from the eye-tracking experiments.

Neonatal resuscitation teams simultaneously process and act upon multiple data streams, perform ergonomically challenging technical procedures, and coordinate their actions within a small physical space. An understanding and application of human factors and ergonomics science broadens the areas of need in resuscitation research, and will lead to enhanced technologies, systems, and work environments that support human limitations and maximize human performance during neonatal resuscitation.

Full textAbstract:
The risk of a needle stick or sharps injury in the operating room (OR) is high due to conditions such as minimal physical protective measures, frequent transfer of sharps, and reliance on human attention and skill for injury avoidance. An ergonomic process improvement project was initiated at a large metro teaching hospital to identify ergonomic risk factors for these OR injuries. To maximize the engagement of the front- end users, an ergonomic process improvement (EPI) team was developed, consisting of representatives from participating OR teams, an employee health nurse and two ergonomists. Surveys, observations, and interviews were conducted to quantify injury risk for the OR teams, evaluate barriers to best practice adherence, and identify opportunities for targeted interventions. Risk mapping was completed for the surgeons, surgical techs and OR nurses identifying double gloving and safe passing zone as areas in need of improvement. Through observation and interviews, researchers identified physical factors relating to musculoskeletal pain and cognitive factors leading to distractions as safety risk concerns. The overall success of the EPI was the engagement of the OR teams and surgeons in the process of identifying risk factors and potential opportunities for ergonomic solutions related to cognitive workload, physical workload, teamwork, and work design for injury prevention. The risk factors identified will provide the basis for developing targeted, effective interventions for eliminating injuries from needles and sharps within the OR.

Full textAbstract:
The learning process between students and lecturers usually occurs face-to-face in class. Technological developments and a continuous pandemic change the learning process to be a face-to-face e-learning process. The mental load during face-to-face learning is very different from learning in e-learning. This study was built using ergonomic thinking that is integrated with the use of e-learning. Cognitive ergonomics see from the point of view of students' comfort in cognitive thinking processes when doing e-learning. Data processing and testing will use a questionnaire derived from the NASA-TLX method. The results obtained from this study are the mental load calculations of each NASA TLX calculation. NASA TLX calculations show that efforts with a value of 267.29 dominate students. It could indicate that in e-learning lectures, students need more effort in conducting lectures. In addition, students experience fatigue while participating in online learning. It can be seen from the average SOFI measurement, which is only 1.26.

Abstract The autonomic nervous system is responsible for modulating peripheral functions in the human body and consists of sympathetic and parasympathetic branches. Its activation affects, among other things, heart rate, respiratory rate, salivation, perspiration, pupillary dilation, and blink rate. For some years now, physiological measurements have found their way into interpreting and translation studies to investigate, in particular, cognitive, emotional and ergonomic demands and stress in translating, interpreting and post-editing. We conducted a meta-review of publications from 1990 until 2020 in order to investigate the relevance of (a) the four constructs of emotional, cognitive and ergonomic demands and physiological stress and of (b) physiological data for translation and interpreting research. With our selection of search terms, we identified 369 publications investigating one of the four constructs, of which 28 use physiological data. Analysis of the 28 studies shows a tendency towards triangulating physiological with other types of data, which reflects the complexity of the investigated tasks and constructs. Moreover, there seems to be an effort to increase sample size, which is an important step towards more robust results in quantitative research in the field.

More workers are involved into interaction with graphic user interfaces most part of the working shift. However, low ergonomic qualities or incorrect usage of graphic user interface could result in risk of unfavorable influence on workers’ health. The authors revealed and classified typical scenarios of graphic user interface usage. Various types of graphic user interface and operator occupations are characterized by various parameters of exertion, both biomechanical and psycho-physiological. Among main elements of graphic user interface are presence or absence of mouse or joystick, intuitive clearness, balanced palette, fixed position of graphic elements, comfort level, etc. Review of various graphic user interface and analysis of their characteristics demonstrated possibility of various occupational risk factors. Some disclosed ergonomic problems are connected with incorporation of graphic user interface into various information technologies and systems. The authors presented a role of ergonomic characteristics of graphic user interface for safe and effective work of operators, gave examples of algorithms to visualize large information volumes for easier comprehension and analysis. Correct usage of interactive means of computer visualization with competent design and observing ergonomic principles will optimize mental work in innovative activity and preserve operators’ health. Prospective issues in this sphere are ergonomic interfaces developed with consideration of information hygiene principles, big data analysis technology and automatically generated cognitive graphics.

Full textAbstract:
Background: The modern history of ergonomics can be traced back to the world war from 1939 to 1945. From the 1960s to the 1990s, there were many changes made to ergonomics. Some of these were cognitive ergonomics, organizational ergonomics, positive ergonomics, and spiritual ergonomics. Ergonomics is becoming more of an issue in organizations in both developed and developing countries since the rise of occupational safety and health. Today, every company in the world puts more thought into making their workplaces safe.
Objective: The goal of this study is to fill in the gaps in the evidence between ergonomics and employee well-being, focusing on ergonomics, ergonomic practices, and employee performance.
Methods: This study uses an exploratory research design and gathers information from secondary sources to back up the title. Research papers are carefully chosen from scientific databases like Scopus, Web of Science, Science Direct, and Google Scholar by making criteria for each part to make sure the idea goes into depth and analyzes the role of ergonomics in improving employee performance.
Results: Most research is done on physical ergonomics and organizational ergonomics. When people do research on ergonomics, they don't think much about how people act and think. Most ergonomics research is also done in industrial and developed countries, which makes sense. When it comes to research and use of ergonomics, developing countries are a long way behind. Most small businesses in developing countries don't care about ergonomics in the workplace.
Conclusion: Accessing and improving ergonomics in the workplace could improve employee performance and productivity while reducing burnout, absenteeism, and turnover rates. So, it's important to study ergonomics more, especially for places like Nepal.

AbstractIn the era of the fourth industrial revolution, human has still a central role. Manufacturing industries have to deal with human sustainability in order to guarantee workers’ health and well-being. Several studies have proved the importance of ergonomics in workplace design and the benefits related to the adoption of the human-centered approach. The enabling technologies of Industry 4.0 are changing the role of the operator and can support him from a physical and cognitive point of view. On the other hand, companies are increasingly implementing lean philosophies, such as World Class Manufacturing, to maintain their competitiveness by reducing wastes and costs. However, the need arises for a comprehensive methodology to support the design of manufacturing equipment considering human factors by integrating Industry 4.0 technologies and World Class Manufacturing elements. It aims at improving both ergonomic and efficiency aspects of the workstation. The proposed methodology allows identifying and in-depth analyzing the problem, thus finding and implementing a solution that complies with all the requirements and constraints defined. Each step of the methodology can be strengthened by Industry 4.0 technologies. The methodology has been experimented in a real case study with a global company of agriculture and industrial vehicles, leading to the design and implementation of a new equipment. Relevant benefits in terms of ergonomics, efficiency, and process standardization have been achieved.

Throughout the COVID-19 pandemic, students face intolerable mental and physical discomfort when taking online classes, directly impacting their learning motivation and academic performance. Related studies indicated that students had negative sentiments regarding online learning. This may be an alarming notion for students, particularly regarding their learning ability and participation in school. To overcome this nuisance, the primary objective of this study was to examine the factors affecting students’ learning motivation and academic performance during online learning using a novel framework of ergonomic appraisal. A total of 316 respondents answered the online questionnaire using a purposive sampling approach through social media platforms. Ergonomic-based indicators for physical, cognitive, and macro-ergonomics were analyzed simultaneously using partial least square structural equation modeling (PLS-SEM). The results showed that the design of the workstation, the use of LMS, access to technology, teaching delivery, temperature level, and visual learning style were found to significantly influence students’ learning motivation, which then impacts the student’s academic performance. Thus, it is essential for those who are facilitating distance learning to keep in mind the factors that could motivate the student. As a result, this paper becomes an avenue to help appropriately plan the course program to ensure its viability and productively engage the students since online learning is becoming increasingly necessary. Further, this article also provides recommendations and implications on assisting schools, educators, and students in aiding a student’s learning motivation and academic performance.

The combination of advances in cognitive neuroscience & the development of powerful, yet portable, devices are enabling real-time assessments in education. Electroencephalography (EEG) & functional near-infrared spectroscopy (fNIRS) are two such neuroimaging tools being explored during instruction, with a current focus on student attention, engagement, & cognitive load. Neural synchrony has been linked with successful knowledge transfer, social interaction quality, engagement level, & shared attention. These studies, along with ergonomic considerations, are the focus of this literature review. Real-time learning assessments can optimize both teacher & student performance & satisfaction. A tailored instruction has the potential to create optimal learning experiences & more-proactively address learning difficulties.

Abstract This paper reports on an empirical study that investigates the translation process in the workplace from a cognitive ergonomic perspective. In particular, the interaction between ten translators employed by a language service provider and the tools they deploy are examined. To that end, we recorded the translators’ workplace activities using keystroke logging, screen recording and eye tracking, combined with short retrospective interviews. We analysed their behaviour in terms of how they switched between the two screens on their desks, how they used different tools and where they invested their visual attention. Data related to productivity and quality are also presented. Among other findings, our data reveal that validation searches for terms and general expressions lead to considerable tool and task switching among professional translators.

Full textAbstract:
The fingerings used by keyboard players are determined by a range of ergonomic (anatomic/motor), cognitive, and music-interpretive constraints. We have attempted to encapsulate the most important ergonomic constraints in a model. The model, which is presently limited to isolated melodic fragments, begins by generating all possible fingerings, limited only by maximum practical spans between finger pairs. Many of the fingerings generated in this way seldom occur in piano performance. In the next stage of the model, the difficulty of each fingering is estimated according to a system of rules. Each rule represents a specific ergonomic source of difficulty. The model was subjected to a preliminary test by comparing its output with fingerings written by pianists on the scores of a selection of short Czerny studies. Most fingerings recommended by pianists were among those fingerings predicted by the model to be least difficult; but the model also predicted numerous fingerings that were not recommended by pianists. A variety of suggestions for improving the predictive power of the model are explored.

Full textAbstract:
Handwriting research lies mostly within discipline-specific boundaries, hindering knowledge transfer across disciplines into academic skills instruction in schools. This paper attempts to review the literature on handwriting across the occupational therapy and education disciplines to propose an interdisciplinary conceptual framework to guide research and intervention on handwriting in the Malay language. This cross-disciplinary review revealed four major factors that may influence Malay language handwriting: i) neuromotor development; ii) ergonomic; iii) orthographic and iv) cognitive factors. The sub-factors under these four major factors also are identified. Many of the neuromotor development and ergonomic factors are derived from the occupational therapy discipline, while the education discipline provides most of the information on orthographic and cognitive factors. As orthography influences handwriting, it is necessary to revisit handwriting from the perspective of languages other than English. In conclusion, an interdisciplinary framework of handwriting synthesised from this crossdisciplinary review will stimulate more coordinated and coherent research on handwriting. The Malay language serves as a future case study for research into orthographies in handwriting.

Full textAbstract:
As technology continues to leap forward and innovations advance, the systems of civil aircraft are becoming increasingly sophisticated and complex. Accordingly, there is a rising amount of information to be processed by pilots in the cockpit, increasing their cognitive burden, which significantly threatens the safety of flight. Thus, designers have formulated cockpit layout principles relating to importance, frequency of use, functional grouping, and operation sequence on the basis of ergonomics, which can effectively reduce the cognitive burden for pilots. The degree to which the cockpit layout of a model conforms to the four design principles can indicate its ergonomic design level. In accordance with the concepts of the above four cockpit layout principles, evaluation methods for determining their respective conformity to the four design principles were proposed in this paper. These methods use the operational sequence of cockpit system controls used in the normal flight mission of the actual aircraft type as the evaluation data source. Subsequently, the total evaluation results for cockpit layout were obtained using the weighted accumulation method. Lastly, the process for evaluating the cockpit layouts of civil aircraft was illustrated using the cockpits of the A320 series and B737NG series as examples. Based on the final evaluation results, the feasibility and effectiveness of the proposed evaluation method was verified.

Full textAbstract:
Although alternative keyboards offer ergonomic benefits over the standard keyboard, the standard QWERTY keyboard is still the most widely used. This study was performed to quantify learning rate percentages for four alternative keyboards (chord, contoured split, Dvorak, and fixed split) and understand how physical, cognitive, and perceptual demands affect learning rate by quantifying these measures. Sixteen proficient typists participated in five, three-sentence typing trials on each alternative keyboard, and nine additional subjects participated in 20 typing trials on one alternative keyboard. Time-to-complete and error percentage were collected after every trial, and subsequent learning rates were calculated. Results demonstrated that the learning rate for the fixed split keyboard was significantly different from the learning rates for the other three keyboards. Learning rate negatively correlated to all types of demand (physical, cognitive, and perceptual), so learning rate was slower with higher demand, regardless of the type of demand. Many alternative keyboards have been shown to have ergonomic benefits, and the results of this study would indicate that the learning rates associated with some of the keyboard designs are such that they can easily be implemented into the workplace without long-term productivity decrements.

This paper presents a methodology to evaluate the accessibility degree in companies, which was developed in a human centred perspective. For this purpose we considered physical, sensorial and cognitive deficiencies. A guide based on this methodology was created to turn the evaluation into an easy and helpful ergonomic tool. The guide was divided into accessibility "to the" workstation and accessibility "in the" workstation, both of them, considering the physical and informational accessibilities. They were divided into two accessibility levels, the minimal and the adequate levels, which meant the accessibility degree of the company. This methodology can also aid in ergonomic interventions for promoting an Inclusive Work Design and Safety for the workers, and for creating at the same time good working conditions, that will increase Human Performance. This tool was evaluated in a large company and implemented in Portugal through the INCLUDE program.

Full textAbstract:
Standing is one of the most preferred working postures in the manufacturing field as it provides a large degree of physical freedom and mobility to the human operators. In addition, the cognitive perceptions of the increase in work effectiveness and productivity rate among the human operators are the reasons this working posture is practiced. However, to stand erect for a long period of time or otherwise known as Prolonged Standing often leads to physiological discomfort, fatigue and even health issues such as Musculoskeletal Disorders (MSDs). The aim of this paper is to review on the effects resulting from Prolonged Standing and disseminates the information on the ergonomic interventions to relieve standing fatigue. Selected journals and research papers related to Prolonged Standing were reviewed and the findings showed that varying the floor conditions such as installing anti-fatigue mat and using shoes with soles would help in relieving discomfort associated with the cumulative effects of Prolonged Standing. Nevertheless, further research is needed to truly quantify the effectiveness of these suggested ergonomics interventions in real world implementations such as in the manufacturing industry.

OBJECTIVE: To extend an existing computer programme for the evaluation and design of shift schedules (BASS 3) by integrating workload as well as economic aspects. METHODS: The redesigned prototype BASS 4 includes a new module with a suitable and easily applicable screening method (EBA) for the assessment of the intensity of physical, emotional and cognitive workload components and their temporal patterns. Specified criterion functions based on these ratings allow for an adjustment of shift and rest duration according to the intensity of physical and mental workload. Furthermore, with regard to interactive effects both workload and temporal conditions, e.g. time of day, are taken into account. In a second new module, important economic aspects and criteria have been implemented. Different ergonomic solutions for scheduling problems can now also be evaluated with regard to their economic costs. RESULTS: The new version of the computer programme (BASS 4) can now simultaneously take into account numerous ergonomic, legal, agreed and economic criteria for the design and evaluation of working hours. CONCLUSIONS: BASS 4 can now be used as an instrument for the design and the evaluation of working hours with regard to legal, ergonomic and economic aspects at the shop floor as well as in administrative (e.g. health and safety inspection) and research problems.

In this article, a cognitive framework for observing learning activities based on human-computer coupling is proposed. The observation is based on the vectorization of a learning situation along with human-computer interaction factors. An evolutionary high-dimensional topology of learning cognitive flow is introduced for human-computer interaction. In addition, the authors have selected a tree topology as the topological structure of a low-dimensional learning space to process the observations for online learning. Furthermore, the mechanism for the BSM (brain cognitive body-situation of coupling-manifold of information) the coupling morphism is presented. The principle for the coupled observation of objects in a cognitive or learning manifold is proposed. Finally, a special system for teaching and learning is programmed to observe and evaluate learning and mental arithmetic training processes. This system not only provides students with a new ergonomic learning model but also records the students' learning processes. Thus, the teachers can summarize the knowledge points automatically rather than manually.

To improve the ergonomic reliability of medical equipment design during the operation process, a method for evaluating the operating procedure of a medical equipment interface according to functional resonance analysis method (FRAM)-Moran’s I and cognitive reliability and error analysis method (CREAM) is proposed in this study. The novelty of this research is to analyze the ergonomic reliability of medical equipment in a more systematic manner and to minimize the impact of human subjectivity and individual differences on the evaluation results of the operation process. To solve the calculation problem of functional resonance in FRAM and to make the evaluation results more objective, Moran’s I was introduced to quantify the deviation degree caused by the individual differences of the subjects. By giving weights based on Moran’s I, the influence of individual differences and subjectivity on the evaluation results can be minimized, to a certain extent. Considering the importance of a special environment, which is not fully considered by the conventional CREAM, the weighting values based on Moran’s I, Delphi survey, and technique for order preference by similarity to an ideal solution (TOPSIS) were adopted to assign weights to common performance conditions (CPCs) in CREAM. The optimal design scheme was selected more objectively than in the conventional method. The validity and practicability of this operation process evaluation method was verified by a statistical method based on ergonomic reliability experiments.

Work efficiency is not only related to objective cognitive performance, but it is also closely related to subjective psychological feelings. The existing research mostly focuses on the human safety tolerance limit from the physiological perspective, and there are few studies on work efficiency. In order to evaluate the work efficiency of humans in a high-temperature thermal-radiation environment, this paper proposes a method of personnel work efficiencies evaluation based on the fuzzy comprehensive evaluation method. In this method, the objective cognitive ability and subjective questionnaire data of human subjects in a thermal-radiation environment were obtained by building a high-temperature thermal-radiation platform, and the ergonomic status score (ESS) was calculated to determine the work efficiency evaluation grade. The results of this study indicate that subjective job satisfaction has a strong influence on work efficiencies. The safe WBGT temperature threshold that can be borne by personnel in a high-temperature thermal-radiation environment is lower than that in a single high-temperature environment. The ergonomic status score decreased significantly with the increase of radiation temperature. When the radiation temperature is 300 °C (WBGT temperature ≥ 33.2 °C), the work should be stopped immediately to ensure the safety and health of personnel. The research results can provide a reference for labor protection in high-temperature working environments.

The application of digital ecosystems to various activity types is an objective reality. One of the areas of activity that is currently undergoing a stage of active digitalisation is the educational system. As a result, a separate segment of digital ecosystems appeared − the digital learning ecosystem. The essential issues in the operation of digital learning ecosystems are the learner’s efficiency and safety when interacting with them. This issue has become relevant due to the recent transition to a remote learning mode because control of the effectiveness and safety of interaction with the digital learning ecosystem has decreased. Thus, the paper puts forward a hypothesis: the efficiency and safeness of a student’s work with a digital learning ecosystem in a remote work depend on three components: the level of digital competence; ergonomics of the digital learning ecosystem; ergonomic organisation of the workplace. An experiment was carried out to research the hypothesis. The students in the first year of studying the bachelor’s qualification level from the Simon Kuznets Kharkiv National University of Economics took part. The Personal Learning Systems was chosen as the studied object. The hypothesis got confirmation during the study. In addition, a heuristic model of student interaction with a digital learning ecosystem was proposed based on the results. According to the model, teaching students such interdisciplinary sciences as cognitive and organisational ergonomics and building an individual learning trajectory will increase the effectiveness of students’ interaction with digital learning ecosystems.

Full textAbstract:
Inspection tasks become more and more important for modern production and complex high reliability systems. A major particularity of inspection tasks is to be seen in the fact that the central work process cannot be observed externally. Although inspections tasks include physical activity, the inspection task itself is basically a perceptional and cognitive procedure. Due to the lack of accessibility of a 'work process' or an execution strategy it cannot be broken into separate work steps and cause-effect-relationships. Thus, common ergonomics intervention and design strategies as used for production and service tasks may not be applied similarly for inspections tasks. Requiring to anticipate the attributes of a potential work design variant without having a complete analysis option at hand, explains why engineering and design of work systems remains mostly an expert task. A conceptual model is required to constitute the application of ergonomics knowledge for the design of inspection tasks by delivering insight into the mechanisms contributing or impairing inspection performance. Therefore a work system model is proposed which aims to integrate the most relevant ergonomics concepts in a consistent frame, based on the formal principles of system theory. The linear combination of different approaches shall allow to represent and to explain the complexity of system behavior. This model is extended by a compatible design approach explaining a general structure of design processes and its relationship to the work system model. On the base of the proposed conceptual approach, the particularities of inspections tasks are outlined. This shall support a systematic design of inspection tasks which lack an objective control both on the working level and on the design level.

SummaryIn this work we present NEUROExos, a novel generation of upper-limb exoskeletons developed in recent years at The BioRobotics Institute of Scuola Superiore Sant’Anna (Italy). Specifically, we present our attempts to progressively (i) improve the ergonomics and safety (ii) reduce the encumbrance and weight, and (iii) develop more intuitive human–robot cognitive interfaces. Our latest prototype, described here for the first time, extends the field of application to assistance in activities of daily living, thanks to its compact and portable design. The experimental studies carried out on these devices are summarized, and a perspective on future developments is presented.

Full textAbstract:
Large scale emergencies are usually responded to by a team of emergency managers or a number of sub teams. Team coordination has attracted considerable research interest, especially from the cognitive, human factors, and ergonomic aspects because the shared situation awareness (SSA) and team situation awareness (TSA) of team members is critical for optimal decision making. This paper describes the development of an information system (SAVER) based on SSA and TSA oriented systems design. Validation and evaluation of the implemented design shows that decision performance is improved by the SAVER system.

As human factors (HF) educators, we often struggle to find good examples or inexpensive tools that allow us to demonstrate basic ergonomic principles. The following computer software allows us to HF educators to demonstrate a variety of basic cognitive not only in a lecture of laboratory environment but also at the convenience of the student who owns a personal computer. Specifically this demonstration will present the concept of a simple reaction time, but with the variations of using different color stimuli and a mouse button click for the response.
