RESUMO

Simulated environments have become better able to replicate the real world and can be used for a variety of purposes, such as testing new technology without any of the costs or risks associated with working in the real world. Because of this, it is now possible to gain a better understanding of cognitive demands when working in operational environments, where individuals are often required to multitask. Multitasking often results in performance decrements, where adding more tasks can cause a decrease in performance in each of the individual tasks. However, little research investigated multitasking performance in simulated environments. In the current study we examined how multitasking affects performance in simulated environments. Forty-eight participants performed a dual visual search and word memory task where participants were navigated through a simulated environment while being presented with words. Performance was then compared to single-task performance (visual search and word memory alone). Results showed that participants experienced significant dual-task interference when comparing the dual-tasks to the single-tasks and subjective measures confirmed these findings. These results could provide useful insight for the design of technology in operational environments, but also serve as an evaluation of MRT in simulated environments.

RESUMO

Organizational Design and Management (ODAM) elements of Ergonomics and Human Factors (E/HF) apply to congress organization. Exemplary delegate and organizer E/HF experience is constrained by shifting requirements, time pressures and financial constraints. E/HF application while organizing the International Ergonomics Association's Triennial Congress in 2021 (IEA2021) is described focusing on delivery platforms considering typical and exceptional (pandemic) constraints, emphasizing ODAM E/HF principles and generalizable lessons. Post-Congress feedback from delegates, session chairs and Congress organizers reveal the Congress as experienced. Presenting virtually allowed on-demand recording access following live sessions and increased question-and-answer flexibility. Frustrations included navigating multiple platforms and insufficient communications. Stakeholders' differing expectations increased organizer workloads and delegate frustration. Maximum virtual presentation benefits require efforts to ensure integrated, human-centered platform development. Simply digitizing traditional Congress sessions ignores potential enhancements. Embracing innovations would help meet delegate communication needs via careful selection and deployment of evolving virtual meeting technologies. Organizational learning strategies can support these efforts.

RESUMO

Very few studies have examined differences between experts' and novices' foot positioning and movements during manual materials handling tasks. The impact of footstep patterns on low back loading needs to be better understood. The goals of this study were to characterize foot placement and movements in novices and experts and to assess their impact on back loading considering the height of grasp. The task consisted in transferring 24 15 kg boxes from a pallet to another. Foot placement and movements were classified with a recently developed taxonomy. Results show that experts' feet remained static more often than novices' feet during the lifting phase. Positioning the feet towards the deposit site during lifting increased asymmetrical moments, especially for novices. Positioning one foot forward increased asymmetrical moments for novices. Overall, footstep strategies are an effective indicator of low back exposure and should be considered in ergonomic studies.

RESUMO

Personas are widely recognized as valuable design tools for communicating dimensions of individuals, yet they often lack critical contextual factors. For those people managing chronic health conditions, the home is a critical context of their patient work system (PWS). We propose the development of 'home personas' to convey essential aspects of the home context to those tasked with designing technologies and interventions to fit it. We used an iterative, multi-stakeholder design process to design 'home personas' for a model population, families caring for children with medical complexity. Each of the four resultant home personas-Multi-level, Customized, Ranch, and Rental-has a unique home layout, pain points, and are described on three dimensions that emerged from the data. This study builds on a foundation of work in the emerging field of Patient Ergonomics, describing a mechanism for distilling rich descriptions of the PWS into brief yet informative design tools.

RESUMO

O objetivo do presente estudo foi identificar quais EPIs foram utilizados pelos cirurgiões-dentistas e a relação destes EPIs com a presença de dores osteomusculares em virtude do novo estilo de vida profissional ocasionado pelo SARS-CoV-2. Foram aplicados dois questionários com a temática por intermédio da plataforma Google Forms®. Os participantes da pesquisa (n= 110) tiveram acesso aos questionários via e-mail e através das redes sociais. A análise de dados foi realizada por meio de teste qui-quadrado com nível de confiança de 95%. Os resultados obtidos demonstraram predomínio de indivíduos do sexo masculino, com idade entre 21 a 29 anos, solteiros, entre 1 a 10 anos de formado, possuindo renda mensal de 1 a 5 salários-mínimos, especialistas, atuando em consultório particular, com atualizações para atendimento durante o período de pandemia. Observou-se relação estatisticamente significativa (p<0,05) na utilização de gorro durante os atendimentos odontológicos para os profissionais que realizaram atualizações para atendimento durante o período de pandemia da COVID-19. Em relação aos demais EPIs não houve relação estatisticamente significativa (p>0,05). No que diz respeito às dores osteomusculares, observou-se relação estatisticamente significativa (p<0,05) apenas entre a utilização de avental descartável e o relato de dores na região do pescoço, ombro e costas. Ademais, não foi possível observar relação estatisticamente significativa (p>0,05) entre EPIs e dores osteomusculares. Pôde-se concluir que uma grande parcela dos cirurgiões-dentistas adotou medidas de proteção contra o novo Coronavírus (SARS-CoV-2), utilizando os EPIs recomendados para executar atendimento durante o período pandêmico. Com relação às dores osteomusculares, os participantes relataram dor com ou sem a utilização de EPIs, porém ao utilizarem avental descartável, houve predominância de sintomatologia na região do pescoço, ombros e coluna(AU)


The aim of this study was to identify which PPE was used by Dental Surgeons and the relationship of this PPE with the presence of musculoskeletal pain due to the new professional lifestyle caused by SARS-CoV-2. Two questionnaires with the theme were applied through the Google Forms® platform. Research participants (n = 110) had access to the questionnaires via e-mail and through social networks. Data analysis was performed using a chi-square test with a 95% confidence level. The results showed a predominance of male individuals, aged between 21 and 29 years old, single, between 1 and 10 years since graduation, having a monthly income of 1 to 5 minimum wages, specialists, working in private practice, with updates for care during the pandemic period. There was a statistically significant relationship (p<0.05) in the use of a cap during dental care for professionals who updated for care during the COVID-19 pandemic period. About the other PPE there was no statistically significant relationship (p>0.05). Regarding musculoskeletal pain, there was a statistically significant relationship (p<0.05) only between the use of a disposable apron and the report of pain in the neck, shoulder, and back. Furthermore, it was not possible to observe a statistically significant relationship (p>0.05) between PPE and musculoskeletal pain. It was concluded that a large portion of dentists adopted protective measures against the new Coronavirus (SARS-CoV-2), using the recommended PPE to perform care during the pandemic period. Regarding musculoskeletal pain, participants reported pain with or without the use of PPE, however, when using a disposable apron, there was a predominance of symptoms in the neck, shoulders, and back(AU)

RESUMO

Nasotracheal intubation is the preferred route for general anesthesia maintenance in patients undergoing maxillofacial surgery or dental procedures. However, compression of the tracheal tube may cause superficial necrosis of the nasal wing and deformation of the external nose. Thus, proper fixation of the tracheal tube during nasotracheal intubation is important for the patient's safety as well as that of the medical staff. Recently, a nasotracheal tube support device has been developed; thus, in this study, the aim was to present and describe the Sverzut nasotracheal tube support device and discuss the advantages of its use during nasal intubation in cervicomaxillofacial surgery. Findings from this study show that the Sverzut nasotracheal tube support device can contribute to the stabilization of the nasotracheal tube and all its connectors, aiding in the maintenance of the airway patency and minimizing the complications related to this type of intubation.

RESUMO

Various subdisciplines of ergonomics science have emerged during the past decades as our insight has been broadened of human and performance. The three main branches of ergonomics have evolved over time focusing on the physical, cognitive, and organizational aspects. But the question is, can these disciplines focus and research enough on the ergonomic aspects of cyberspace and Industry 4.0 technologies? Cyber-technologies of the Fourth Industrial revolution are dramatically imposing themselves on our life and work. This has been led to emerging cyber-aspects for human work and life. Hence, many sciences, mainly applied ones, have upgraded to their cyber versions to deal with the emergent issues, usually with a new name, including the cyber prefix. Cyber-medicine, cyber-health, cyber-commerce, and cyberpsychology are some examples. Also, ergonomics requires a similar look. Ergonomic benefits and threats of Industry 4.0 technologies must be considered in an integrated manner. This paper addresses this issue. First, the emergence and development of ergonomics and its subdisciplines chronologically is reviewed. Then, Cybergonomics as a new name and concept is proposed and defined as the ergonomics of Industry 4.0 era. Justification for this portmanteau is described, and an outline of the new realm is explained. Finally, a research road map is proposed for this new subdiscipline of ergonomics.

RESUMO

Hotel room cleaners frequently report job-related pain, with high rates of work-related musculoskeletal disorder injuries established for this group of workers. Surprisingly, there is limited published research documenting the impact of interventions to reduce ergonomic-related injury risks specific to hotel room cleaners' job tasks. In this study focused on hotel bathroom-cleaning and furniture-dusting tasks, twelve experienced hotel room cleaners used their standard method and a risk-reduction method-a tool with a handle that could extend, to perform these tasks. The female study participants' average age was 45.3 (SD 8.7) years with an average of 10 years of work experience as cleaners (range: 0.8-26.0 years). Trunk kinematics and a low back injury risk assessment were measured using the Lumbar Motion Monitor. All study metrics were significantly reduced when cleaning tasks involved use of adjustable, long-handled tools (p < 0.05). This study demonstrated that commonly available cleaning and dusting tools with extendable handles can significantly reduce low back injury risk among hotel room cleaners and potentially reduce injury risk to other body parts known to be the site of musculoskeletal disorders in this workforce. The study findings suggest that cleaning or housekeeping jobs in other industries where these same tasks are performed could benefit from use of extended-handle tools like those investigated here.

RESUMO

Many industrial sectors still lack automation resources to optimize their production processes, aiming to make manufacturing leaner and offer better working conditions to operators. Without these improvements, workers can suffer physical and even psychological damage from the ergonomic risks of the activities performed. Thus, the aim of this paper is to present the ergonomic evaluation of packaging tapes workstation before and after the implementation of an automatic packaging machine, called Guzzetti. In the Guzzetti context, the paper shows the implementation of an electrical system based on controlling a mechanical device powered by servomotors and controlled by a PLC is necessary. For ergonomic evaluation, the paper presents the application of three methods: Suzanne Rodger, Strain Index, called Moore and Garg and REBA (Rapid Entire Body Assessment). With the results collection, was possible to obtain improvements in ergonomic risks that changed from the intermediate level to low level in all methods.

RESUMO

Musculoskeletal diseases represent a constant phenomenon in occupational health and safety (OHS) despite the large effort at governmental and technical levels. In the industrial context, numerous studies have dealt with the evaluation of the physical demand of workers. Moreover, numerous studies have investigated the problem, providing tools for ergonomics analysis. However, practical approaches aimed at integrating ergonomics issues in risk assessment activities are still scarce. To reduce such a gap, the current study proposes a procedure for the evaluation of the static working postures of workers to be included in the risk assessment activities. Such an approach is based on the ISO 11226 standard, providing a practical checklist that can be used both at the workstation's design stage and during risk assessment activities. Its effectiveness was verified through a case study at a manufacturing company. The results achieved showed that as well as the non-conformity of the workstations' design, the lack of training of the operators on how to maintain a neutral posture while working can also lead to awkward postures of the trunk and head. Additionally, the proposed methodology allowed us to verify the correctness of each workstation based on the physical characteristics of the workers, providing a useful guideline for the company managers on how to properly assign working tasks.

RESUMO

PURPOSE: To investigate the usefulness and ergonomics of a newly developed robotic system for flexible ureteroscopy (easyUretero). MATERIALS AND METHODS: During in vitro testing, six participants performed renal stone removal four times in an artificial kidney-ureter-bladder model. Each participant manipulated a single-use digital flexible ureteroscope (LithoVue) with their hands and the robotic system, sequentially. We compared the task completion times of each participant. The ergonomics of and operational satisfaction with each procedure were assessed by questionnaires. In vivo tests evaluated the operability and safety of the robotic system in two live female pigs. We checked that all the steps of flexible lithotomy for renal stones could be completed individually. RESULTS: The task completion time with the robotic system during in vitro testing was significantly longer than with manual ureteroscopy regardless of the operator's competence level (expert professors: 282.6±92.4 seconds vs. 73.6±43.3 seconds, p<0.001; fellows: 247.5±57.7 seconds vs. 95.8±43.7 seconds, p<0.001; residents: 281.3±111.0 seconds vs. 188.6±138.6 seconds, p<0.001). The residents took more time to remove the upper and mid caliceal stones with the robotic system. The ergonomic evaluation was better for the robotic system, but operational satisfaction was lower, and there was no statistical difference among the groups. In vivo tests showed that all the steps of robotic flexible ureteroscopy could be completed without difficulty. No safety issues were encountered during the procedure. CONCLUSIONS: The robotic system (easyUretero) was ergonomic and safe for flexible ureteroscopy and laser lithotripsy for renal stones.

RESUMO

OBJECTIVE: There is a research gap regarding the way managers and employee representatives respond to Labour Authority interventions targeting work-related psychosocial and ergonomic risk factors. The present study aimed to determine if (I) labour inspections and (II) guidance-through-workshops led by inspectors were perceived by the target audience as equally useful and educational; and to determine if utility and enhanced knowledge were associated with the implementation of measures to prevent work-related risk factors. Finally, it aimed to determine if the managers in the intervention groups to a greater extent than the controls reported implementing such measures. RESULTS: Managers and employee representatives in both intervention groups reported a high level of perceived utility as well as a high level of enhanced knowledge. Both utility (p < 0.05) and enhanced knowledge (p < 0.05) were significantly associated with the implementation of, or plans to soon implement, measures to improve working conditions. When compared to controls, implemented measures, or plans to implement measures, were reported significantly more frequently by managers in the inspection group (p < 0.05).

RESUMO

The objective of the present work is for assessing ergonomics-based IoT (Internet of Things) related healthcare issues with the use of a popular multi-criteria decision-making technique named the analytic hierarchy process (AHP). Multiple criteria decision making (MCDM) is a technique that combines alternative performance across numerous contradicting, qualitative, and/or quantitative criteria, resulting in a solution requiring a consensus. The AHP is a flexible strategy for organizing and simplifying complex MCDM concerns by disassembling a compound decision problem into an ordered array of relational decision components (evaluation criteria, sub-criteria, and substitutions). A total of twelve IoT-related ergonomics-based healthcare issues have been recognized as Lumbago (lower backache), Cervicalgia (neck ache), shoulder pain; digital eye strain, hearing impairment, carpal tunnel syndrome; distress, exhaustion, depression; obesity, high blood pressure, hyperglycemia. "Distress" has proven itself the most critical IoT-related ergonomics-based healthcare issue, followed by obesity, depression, and exhaustion. These IoT-related ergonomics-based healthcare issues in four categories (excruciating issues, eye-ear-nerve issues, psychosocial issues, and persistent issues) have been compared and ranked. Based on calculated mathematical values, "psychosocial issues" have been ranked in the first position followed by "persistent issues" and "eye-ear-nerve issues". In several industrial systems, the results may be of vital importance for increasing the efficiency of human force, particularly a human-computer interface for prolonged hours.

RESUMO

BACKGROUND: In order to reduce work-related upper limb disorders, the Swedish Work Environment Authority introduced an occupational health surveillance targeting hand-intensive work. A process model, aimed at supporting the employers as well as the occupational health service provider (i.e., ergonomist) in the work process with the occupational health surveillance, was developed. The objective of this qualitative study was to explore ergonomists' experiences of the execution of occupational health surveillance for hand-intensive work when following the novel process model as well as factors influencing the execution. METHODS: Semi-structured individual interviews were conducted with ten ergonomists on one occasion regarding their experience of following the work process. Qualitative content analysis with an inductive approach was used for analyzing the data. RESULTS: The ergonomists' experiences were summarized in one theme "A joint roadmap supporting a participatory process" and two categories "Clear structure provided by the components" and "The process influenced by collaboration and context". The ergonomists valued being guided by the systematics of the model, which provided structure and clarity in their work. Factors affecting the execution were related to communication deficiencies and uncertainties regarding expectations between different roles and functions (e.g., ergonomists and contact person, lack of information to workers). Additional factors, for instance, companies' routines and the ergonomist's intra-organizational support, such as access to IT-resources, could also affect the process. CONCLUSIONS: The findings reveal that this process model facilitates the ergonomists' work and cooperation with a client company. However, the process model needs to be developed and accompanied by a guideline with information related to the process, including e.g., description of a start-up meeting and of the roles/functions of the involved parties.

RESUMO

OBJECTIVE: The strict implementation of occupational health and safety policy curbs exposure to occupational hazards. However, empirical evidence is lacking in the Ghanaian context. This review primarily aimed to explore exposure to occupational hazards among healthcare providers and ancillary staff in Ghana. DESIGN: A scoping review was conducted based on Arksey and O'Malley's methodological framework and Levac et al's methodological enhancement. DATA SOURCES: Searches were conducted of the PubMed, MEDLINE, CINAHL, Embase, PsycINFO and Scopus databases, as well as Google Scholar and websites of tertiary institutions in Ghana, for publications from 1 January 2010 to 30 November 2021. ELIGIBILITY CRITERIA: Quantitative studies that were published in the English language and focused on occupational exposure to biological and/or non-biological hazards among healthcare professionals in Ghana were included. DATA EXTRACTION AND SYNTHESIS: Two independent reviewers extracted the data based on the type of occupational exposure and descriptive characteristics of the studies. The data are presented in tables and graphs. A narrative summary of review findings was prepared based on the review research questions. RESULTS: Our systematic search strategy retrieved 507 publications; however, only 43 met the inclusion criteria. A little over one-quarter were unpublished theses/dissertations. The included studies were related to biological, psychosocial, ergonomic and other non-biological hazards. 55.8% of the studies were related to exposure to biological hazards and related preventive measures. In general, health workers were reported to use and comply with control and preventive measures; however, knowledge of control and preventive measures was suboptimal. CONCLUSION: Work is needed to address the issue of occupational health hazard exposure in Ghana's health system. More research is needed to understand the extent of these exposures and their effects on the health system.

RESUMO

BACKGROUND: The present study aimed to investigate the possible association between specific ergonomic and individual risk factors and musculoskeletal pain (MSP) in the back, shoulder, hip and knee region in workers aged 50-65y. METHODS: The study was a population based cross-sectional survey. The study population comprised citizens born between 1952-1966, living in Esbjerg municipality, Denmark, ultimo 2016 (n = 23,463). A questionnaire was sent electronically or by mail. The analysis included the working population only. A multivariate logistic regression was used for each of the following dependent variables; musculoskeletal pain for the past 3 months in the back, shoulder, hip and knee, where independent variables included ergonomic exposure, age, sex, body mass index (BMI) and leisure time physical activity (LTPA). RESULTS: The overall response rate was 58% and the data of individuals at work (n = 9,263) demonstrated several ergonomic exposures with increased odds for pain in specific regions. Exposure to back twisted or bend, squatting or lying on knees and to carrying or lifting were associated with musculoskeletal pain in the back, whereas exposure to back twisted or bend, arms above shoulder and repeated arm movement were associated with pain in the shoulder. Exposure to back twisted or bend, repeated arm movement, squatting or lying on knees and to carrying or lifting were associated with musculoskeletal pain in the hip. Important individual risk factors were also identified. Increasing age was significantly associated with increased pain in the hip but associated with less risk for pain in the back and shoulder. Males had higher odds for pain in the back and knee compared to females but lower odds for pain in the hip. BMI was particularly important for knee pain. The level of LTPA did not have an important association with MSP in any region. CONCLUSION: There is a significant positive association between ergonomic exposures and musculoskeletal pain, which were specific for the back, shoulder, hip and knee. In addition, the data demonstrated a differential association with age, sex and BMI. This needs to be considered for the treatment and classification of musculoskeletal pain and for future preventive initiatives.

RESUMO

BACKGROUND: Ergonomics in design is intended to close the gap between what is designed and the real work. This study discusses the creation of technical ergonomics requirements for the basic design stage of workshops on offshore platforms. OBJECTIVE: This paper intends to show how the ergonomics discipline contributes to integrating knowledge on the real work of the maintenance crew with the design. METHODS: This case study uses procedures, data collection, and analysis guided by the Ergonomics of the Activity's (EA) theoretical framework, focused on design projects. RESULTS: The results show how ergonomics contributed to a better understanding of maintenance work, as well as how this knowledge was integrated into the project design. This occurred both through the construction of a new layout and equipment list, and through the development of technical specifications. These products enable greater operational efficiency, reductions in the costs of alterations in the next stages of the project, and improvement in working conditions. CONCLUSIONS: This work points to the need for new studies on platform maintenance work, in addition to studies that deepen the debate on consolidating ergonomics practice in design projects.

RESUMO

BACKGROUND: Musculoskeletal risks (MSRs) are a major concern among construction warehouse workers due to the lifting, carrying and lowering of heavy loads. OBJECTIVE: The objective of this study was to reduce MSRs among warehouse workers in the construction industry using virtual modelling and analysis of activities. METHODS: A preliminary study was carried out using the Standard Nordic Questionnaire. Biomechanical analysis, Ovako Working posture Assessment System (OWAS) and Rapid Upper Limb Assessment (RULA) were used to analyse the material handling activities. Virtual modelling was used develop the manikins with autoclaved aerated concrete (AAC) blocks at different carriage modes and stacking heights for the analysis. RESULTS: The preliminary study results revealed a higher prevalence of risk at their lower back (73.24%) among the construction warehouse workers. Biomechanical analysis showed a higher risk at L4-L5 joint of lumbar spine during overhead and bending postures for stacking the blocks. Posture analysis results of OWAS indicated a lower risk in overhead carriage mode. Detailed analysis with RULA confirms this result. Mean compressive force values at stacking heights were showed a significant difference (p < 0.05) in 8, 13, 18 and 21 kg AAC blocks. However, stacking height with a range of 120-140 cm was found as safer to the workers by considering all block sizes. CONCLUSION: An ergonomic intervention based on safer stacking heights was developed to reduce MSRs to an acceptable range. It improves productivity of handling the AAC blocks by reducing the cycle time. The intervention can be adapted for handling of similar materials in the construction industry.

RESUMO

BACKGROUND: A significant error that may occur during ergonomic risk assessment and invalidate assessment reliability corresponds to technique selection. This study aimed to develop a new tool called the Decision Aid Tool (DAT) to reduce pen-paper observational technique selection errors. METHODS: This quasi-experiment before-after study was performed in three phases. In the first phase, the participants' skills in technique selection were examined by showing them 20 videos of different single-task jobs. In the second phase, the DAT was designed using pen-paper observational techniques. Finally, in the third phase, 115 occupational health specialists included in the study through purposive sampling of experts evaluated the tool's efficacy. RESULTS: The results of the first phase showed that 62% of participants made an error in selecting the proper technique. The mean and standard deviation scores from the first and third phases were 11.4 ± 6.59 and 39.01 ±1.89, respectively. The mean scores increased significantly after using DAT, and 97.5% of participants could correctly select task techniques. CONCLUSIONS: The efficacy of DAT was confirmed in a quasi-experimental before-and-after study. Using DAT increases the participants' ability to choose the correct technique. The DAT can be functional for practitioners to select the pen-paper observational techniques correctly under the purpose of assessment, the body areas, and the characteristics of the task to be assessed.
