Proceedings of the Human Factors and Ergonomics Society Annual Meeting 44, n. 37 (luglio 2000): 689. http://dx.doi.org/10.1177/154193120004403746.
Abstract (sommario):
Even though a large amount of ergonomic data and recommendations are available, tools, equipment and products are quite frequently subject to considerable ergonomic deficiencies. The reason for this is that knowledge of ergonomics is not as widespread as the expert would like it. The designer of work places and equipment usually has a rather small background of ergonomics. In many cases it is difficult even for the ergonomist to compress the available knowledge into tables and charts. A computerised assistance system could be of great help

Abstract (sommario):
Industries need a mechanism to monitor the workers’ safety and to prevent Work-related Musculoskeletal Disorders (WMSDs). The development of ergonomics assessment tools helps the industry evaluate workplace design and worker posture. Many studies proposed the automated ergonomics assessment method to replace the manual; however, it only focused on calculating body angle and assessing the wrist section manually. This study aims to (a) propose a wrist kinematics measurement based on unobtrusive sensors, (b) detect potential WMSDs related to wrist posture, and (c) compare the wrist posture of subjects while performing assembly tasks to achieve a comprehensive and personalized ergonomic assessment. The wrist posture measurement is combined with the body posture measurement to provide a comprehensive ergonomics assessment based on RULA. Data were collected from subjects who performed the assembly process to evaluate our method. We compared the risk score assessed by the ergonomist and the risk score generated by our method. All body segments achieved more than an 80% similarity score, enhancing the scores for wrist position and wrist twist by 6.8% and 0.3%, respectively. A hypothesis analysis was conducted to evaluate the difference across the subjects. The results indicate that every subject performs tasks differently and has different potential risks regarding wrist posture.

Abstract (sommario):
This paper presents the results of an implementation evaluation for a participatory ergonomics project, in two plants run by a company involved in primary aluminium processing. The logbooks kept by the ergonomists, together with observations of project meetings and post-intervention interviews with Ergo group members, were the basic materials used in analyzing the implementation. The analysis includes a comparison between the projected and actual outcomes of the project, examines the contextual factors that explain the gaps observed, and questions the principles underlying the intervention. The results point to the need for ergonomists to have a dynamic vision of implementation evaluations, which will allow them to adjust and refine their intervention theory.

Abstract (sommario):
Due to the high-risk nature of musculoskeletal disorder development in dentistry, ergonomic education and evaluation are needed in predoctoral programs. The purpose of this pilot study is to investigate perceptions of ergonomics within the School of Dentistry (SOD), current ergonomic clinical practices among third- and fourth-year dental students, and dental students' level of knowledge of ergonomics. The study was conducted utilizing an explanatory sequential mixed methods design to collect both quantitative and qualitative data. While the data collection occurred in three phases, this article will primarily focus on Phase III. The three phases of data collection were: Phase I consisted of a questionnaire distributed to all dental students; Phase II consisted of clinical observations of third- and fourth-year dental students' ergonomic postures during patient care, and Phase III consisted of SOD faculty focus groups to determine perceptions of ergonomic education with the predoctoral curriculum. Data revealed three overarching themes: (1) Didactic to clinical disconnect, (2) Elective impacts, and (3) A ready commitment. Phase I yielded a response rate of 84% (n=135). Phase I responses noted that 81.5% (n=110) of the dental students reported experiencing musculoskeletal pain. Ninety-three dental students reported receiving one or two lectures on ergonomics; however, 60% (n=27) failed to implement proper ergonomic postures while caring for patients in the clinical environment during Phase II. Phase III, revealed faculty support of ergonomic evaluation and correction among dental students. The results indicated a need to establish and implement an ergonomic evaluation and corrective program within the SOD

IIARD International Journal of Economics and Business Management 9, n. 8 (9 febbraio 2024): 56–65. http://dx.doi.org/10.56201/ijebm.v9.no8.2023.pg56.65.
Abstract (sommario):
The study investigated the organisational ergonomics framework and Business Educators’ job commitment in universities in Rivers State. Two research questions were answered, while two hypotheses were tested. A correlational research design was adopted for the study. The population of the study comprised 47 business educators from three universities in Rivers State. The census sampling technique was adopted due to its manageable size. Two structured instruments (OEFQ and BEJCQ) validated by experts in business education and measurement and evaluation were used for data collection. The reliability index of 0.93 and 0.76 was obtained, respectively, using Cronbach’s alpha. Data were analysed using mean, standard deviation, and Pearson Product Moment Correlation (r). A post-hoc t-transformation test was also carried out to test the significance of the correlation coefficient. Findings from the study revealed a positive and significant relationship between production ergonomics, proactive ergonomics, and Business Educators job commitment in universities in Rivers State. Based on the findings, the researchers concluded that the organisational ergonomics framework is a comprehensive approach that improves workplace ergonomics and further recommended that university management should provide ergonomic tools and equipment that are adjustable and suitable to individual body sizes and capabilities that can help to prevent musculoskeletal disorders and improve overall comfort. Institutions should also establish an ergonomic committee with the responsibility of training faculty members about proper ergonomics as well as conducting regular evaluations of equipment and tools.

Abstract (sommario):
Probing into the industry characteristics of construction operations and the necessity to make ergonomic improvement for construction operations, this paper analyzed the current research situation of the literature both at home and abroad which apply ergonomic principles to make improvement in construction operations. This study shows that the existing research on ergonomic improvement of construction operations mainly focus on construction safety and specific operations improvement, at the same time, the system research on the ergonomic improvement of construction operations is less. Making a China's leading internationalized construction service company as the object of empirical research, this paper designed the evaluation index system of construction operations’ man-machine-environment system from three factors of human, machine and environment. And applying the Fuzzy Comprehensive Evaluation Method, the paper evaluated the validity of the man-machine-environment system. At last, aiming at the evaluation results, some improvements were given in view of Ergonomics.

Abstract (sommario):
By virtual reality technology and ergonomics theory, a basic method of ergonomic analysis on virtual maintenance of civil airplane is herein presented based on DELMIA modeling tool. The method is characterized by two steps: (1) establish the appraisal indexes of ergonomics on virtual maintenance of civil airplane; (2) give a quite complete ergonomic analysis and confirmation system flow chart. By defining maintenance cases and simulating the virtual maintenance process under the DELMIA platform, it is possible to accomplish the ergonomic analysis and evaluation with respect to the ergonomics indexes. The strengths of this method are in its ability to provide the available data and experience for further ergonomic design research and in its broadly applicable 3-D digital human model well suited for computer simulation. Furthermore, because the ergonomic analysis problem in maintainability design is indeed a simulation and confirmation process, the use of simulation techniques and confirmation techniques in this work lends itself to maintainability concurrent design of civil airplane. The ergonomic analysis method is demonstrated using vision analysis as an example.

Abstract (sommario):
Eventhough the production technology and capacity have been improved, manpower is indispensable. Coach production industry is one of the heavy industries. Production processes are mostly manpower in addition to automation and mechanization in these factories. Ergonomics is the one of the most important subject to increase the production efficiency and job security in heavy industry factories which use manpower heavily. Ergonomics is the field which aims to reduce the accidents and job related illnesses, anatomic problems in human body, psychological and physiological fatigue and minimize the workforce loss. Ergonomic statement evaluation is possible with providing ergonomic criteria such as anthrometric, environmental condition, and work place.
In this study, some experimental studies are done in order to evaluate the ergonomical conditions in chassis frame production, cataphoresis, paint shop, assembly, and quality inspection processes. The experimental studies include static and dynamic anthrometric measurements on a choosen process and experimental subject workers. The environmental conditions namely, temperature, humudity, lightening, air quality, and noise level are periodicly meausured with proper measuring devices and these data are recorded. The results are used to make an inference with comparing literature. Furthermore, inconvenient results are studied in order to determine the relation with work accidents, work related illnesses and total efficiency parameters in the factory. This study is considered to be a guidance for the effects of ergonomical conditions on workplace safety and health, work accidents and occurences, and production efficiency.

Abstract (sommario):
Mining is often associated with the risk of Work-Related Musculoskeletal Disorders (WRMSDs). Despite being a coal-rich country, Pakistan’s mining sector stays behind in terms of occupational health and safety. Only a few research studies have been conducted on ergonomics in the mining industry. The current study aimed at evaluating workstations for WRMSDs and ergonomic factors among coal mine workers. Survey data were gathered from a total of 103 workers using a structured questionnaire. Information on the incidence of musculoskeletal disorders was obtained using the Standardized Nordic Questionnaire. The questions about ergonomics awareness, workstation, environment, demands, and risks were based on the available literature studies. The association between the incidence of WRMSDs and age was explored using chi-square analysis. The results showed a high rate of uneducated workers with a lack of ergonomics awareness. Back, shoulders, and legs were the most vulnerable body areas to WRMSDs. A significant association between workers’ age and WRMSDs was found. The workers’ opinion towards workstation was at a very low level. The current work conditions were found to have risks of potential hazards and economic losses. Ergonomic interventions are suggested to be developed and implemented to improve workplace conditions.

Abstract (sommario):
A comprehensive ergonomics evaluation of retail ice cream shop operations was performed. Although the analysis was initiated by interest in examining the ergonomics of scooping ice cream, a broad systems-based analysis of shop operations was recommended so that the overall health, safety and productivity of employees could be enhanced. The analyses performed included manual materials handling analysis (using psychophysical data), passive and active surveillance, quantification of forces required to scoop ice cream, and anthropometry and workplace design assessments. Walk-through hazard identification, informal employee interviews and industry-wide passive surveillance provided direction for the selection of analyses. Both laboratory and field data collection were conducted. The primary ergonomic deficiencies uncovered included poor postures and high muscular forces associated with scooping ice cream. Recommendations were made in each of these areas, as well as in the area of work practices, workplace design, and manual materials handling.

Abstract (sommario):
Conducting ergonomic risk assessment is important as it helps employers identify the significant risks in their workplace and will resulting in adequate preventive measures. Simpler observational techniques is one of the types of ergonomic evaluation tools which is commonly used. It is practical, user-friendly and gathering information from both employees and practitioners. This paper presents comparisons between two observational ergonomics tools for determining ergonomics risk factors for work-related musculoskeletal disorders. The Rapid Entire Body Assessment (REBA) and Quick Exposure Check (QEC) were used to assess 296 employees participating in the study from all 12 sections which involved different work tasks in a steel factory. The results are compared using three risk categories (low, moderate, high). Standardised Nordic questionnaires was also used for evaluating the musculoskeletal disorders and effects on working. Data were gathered using questionnaires and evaluations taken at workstation. The findings show the results analyzed using weighted kappa statistic and prevalence of musculoskeletal disorders among workers.

Abstract (sommario):
Purpose This paper aims to perform the real-time and accurate ergonomics analysis for the operator in the manual assembly, with the purpose of identifying potential ergonomic injuries when encountering labor-excessive and unreasonable assembly operations. Design/methodology/approach Instead of acquiring body data for ergonomic evaluation by arranging many observers around, this paper proposes a multi-sensor based wearable system to track worker’s posture for a continuous ergonomic assessment. Moreover, given the accurate neck postural data from the shop floor by the proposed wearable system, a continuous rapid upper limb assessment method with robustness to occasional posture changes, is proposed to evaluate the neck and upper back risk during the manual assembly operations. Findings The proposed method can retrieve human activity data during manual assembly operations, and experimental results illustrate that the proposed work is flexible and accurate for continuous ergonomic assessments in manual assembly operations. Originality/value Based on the proposed multi-sensor based wearable system for posture acquisition, a real-time and high-precision ergonomics analysis is achieved with the postural data arrived continuously, it can provide a more objective indicator to assess the ergonomics during manual assembly.

Abstract (sommario):
Musculoskeletal disorders are some of the most frequent manual work disorders. Employers worldwide pay high costs for their treatment and prevention. We present an innovative method for designing an ergonomic workplace. This method uses new technologies and supports not only ergonomics, but also a general improvement in the designing of the manufacturing process. Although many researchers claim that there is a huge potential for using new disruptive technologies like virtual reality and motion capture in ergonomics, there is still a lack of a comprehensive methodological basis for implementing these technologies. Our approach was designed using the expert group method. We can validate the manufacturing process and the ergonomics using a motion capture (MoCap) suit and a head-mounted display (HMD). There are no legislative restrictions for the tools which are used for ergonomic analyses, so we can use our outputs for workplace scoring. Firstly, we measure the anthropometrics of the proband. Then the proband is immersed in virtual reality and they go through a manufacturing process during which ergonomics data are collected. The design of a particular workplace or multiple workplaces can be validated based on the reactions, measurements, and input in real-time. After processing the data, the workplace can be adjusted accordingly. The proposed method has a time and economic benefit for workplace design, optimisation of workplace ergonomics, and shortens the time required for designing the production line layout. It also includes optional steps for validation using conventional methods. These steps were used for method validation on a representative workplace using on-site experiments. We validated it on a group of 20 healthy operators working in automotive production (age 22 to 35). A comparison study describes the classic methods of workplace ergonomics evaluation, compares the classic evaluation using biomechanical analysis, modern evaluation using a MoCap suit, and connection with virtual reality. We have proved the validity of the method using the comparison study. The results also showed other potential issues which can be further examined: like the role of peripheral vision or haptic feedback.

Abstract (sommario):
Cars are a media fulfilling vital part of the society's need of transports as well as representing an icon of the technical development by underlining critical aspects of man and machine interface. However, various studies show that drivers experience pain and fatigue and also get disorders due to frequent or longterm driving at poor body postures. Through integration of ergonomics into the early design phase these issues can be minimized. Comfort and safety are of special importance when designing car interiors. Comfort is complex. Interior parameters such as; aesthetics, cabin space, ease of reaching controls, luminance, noise, odor, seat design, styling, climate and vibration affect the driving experience. Perceived comfort is to some extent possible to replicate by computer simulation of the human being, which at the same time could illuminate ergonomics by means of various ergonomic evaluation methods in some case integrated in these tools. This paper is a survey of such three tools, ANNIE-Ergoman, JACK and RAMSIS, used for human simulation and ergonomic evaluation. By these tools it is possible to evaluate clearance, comfort, field of vision and reach. The tools are compared and the comparison shows that all three tools have great potential in evaluating car interiors ergonomically in the early design phase. But the comparison also highlights differences between these tools and areas where one tool is superior the other. The paper points on areas as: manikins' skin representation and manikin's movements require further improvements. The paper also underlines the importance having tool-users with insight in the ergonomic evaluation methods. Furthermore, enhancement of the ergonomic evaluation methods and the integration between simulation and ergonomic evaluation methods are also needed.

Abstract (sommario):
Due to the increasingly high proportion of manual activities in production processes, there is a constant risk of musculoskeletal disorders or work-related injuries. The risk of these problems is exacerbated by the trend towards an ageing working population. European legislation is pressing for improved working conditions to eliminate the risks associated with health problems for workers. For this reason, the application of ergonomics in this field is growing. Musculoskeletal disorders, which are most often caused by inappropriate working postures, are a major problem. There are many methods for evaluating working postures. However, there is a high degree of subjectivity in the risk assessment. Motion capture kinematic suits can ensure the objectivity of the assessment. This article discusses research on ergonomics assessment using motion capture technology. A systematic literature search method was used for the research, beginning with the determination of the research procedure, through the definition of the research queries, to the formulation of the research itself to identify relevant sources. The study presents the most widely used methods for assessing the ergonomics of work positions using motion capture technology, their advantages, and disadvantages. It also follows the trend in the number of publications between 2010 and 2022 in countries where the topic is most frequently addressed and in the industries where motion capture technology is used for ergonomics assessment in general. The research showed that this approach is most often used in industry and logistics, and less frequently in healthcare and sport. The authors agree that the most frequently used ergonomics assessment methods are not complex enough to be used in combination with motion capture and that a combination of the two is needed. At the same time, this technology has become very important in the field of ergonomic evaluation of work positions, offering a higher degree of objectivity, or can be combined with the use of virtual reality, but the evaluation systems are still not error-free and there is a need for continuous improvement.

Abstract (sommario):
This paper presents a system for successfully returning an injured employee to work through a multi-disciplinary approach. It details a process that interfaces physical and occupational therapists, rehabilitation specialists and ergonomists, among others. The aims of an effective and efficient occupational rehabilitation process are to ultimately reduce the societal costs of health care. The factors that contribute to these costs are many, and can be influenced by the behavior of the injured worker, the employer, the doctors and other health care providers. This paper discusses the complementary functions of the ergonomist and the therapist: the ergonomist, through workplace evaluation and redesign, considers the external factors that influence an individual's performance; the therapist evaluates and aims to improve the internal factors that affect an individual's performance. A match or mismatch between the physical demands of a job and an injured employee can then easily be detected by comparing the results of an ergonomic assessment and patient evaluation by a therapist. The authors conclude by discussing problems and benefits encountered through this approach.

Abstract (sommario):
Ergonomics is an important validation content in vehicle product development. The traditional evaluation method of ergonomics adopts physical mockups or prototypes, which is very costly, and is inconvenient to modify, and usually cause prolonged development cycle-time. In this paper, in conjunction with enterprise’s requirements, an ergonomic validation equipment system, which has adjustable main parts, was developed. Firstly, requirements were analyzed, and target model cars ranges were determined, and ergonomic contents which can be validated using this equipment were clarified. The packaging characteristic of the passenger car was analyzed, and the reference fiducial marks system used for packaging design were determined. Based on the requirement of occupant accommodation, anthropometries of target population were statistically analyzed. By using revised SAE J1517 H-Point curves models, the drivers’ seating space was designed, as well as the requirement of the driver seat track travel. Based on the analysis of packaging data of passenger cars, and considering the possible changes, controls such as steering wheel, pedals, sticks, etc., were packaged.

Abstract (sommario):
Over the years, forestry-related professions have been consistently considered as one of the most hazardous occupations around the world. Awareness to address this issue through ergonomic improvement interventions is increasing, yet insufficient information is available about ergonomic conditions of Nigerian carpentry and furniture-making (CFM) enterprise. This study evaluated the ergonomics of CFM at the Illoabuchi cluster sawmill/wood market in Port Harcourt, Nigeria using qualitative and quantitative approaches. The carpenters/furniture makers (CFMs) were exclusively males 51.9% of them were within the age of 26 and 35 years with 72.2% of them being married. The height of tables is weakly positively correlated with the height of CFMs (r = 0.250, p < 0.026), implying that a vast number of the tables used were not anthropometrically matched. The occupational hazard outcomes frequently suffered by the CFMs included bruised/hands cut (34.4%), back pain (25.9%), nasal infection (25.9%), muscle pain (8.6%), and eyes infection (5.2%). These findings provide evidence by which the ergonomical target interventions to reduce future hazards and also to lessen the impacts of previous hazards on CFMs can be implemented.

Abstract (sommario):
Objectives Objective evaluation of the ergonomic risk of common otolaryngology procedures and assessment of work-related musculoskeletal pain and injury. Study Design Cross-sectional intraoperative assessment and survey. Setting Department of Otolaryngology at a tertiary children’s hospital. Subjects and Methods Sixteen otolaryngology attendings, fellows, and residents participated in a blinded study. Intraoperative ergonomics was assessed for tonsillectomies, adenoidectomies, and tympanostomy tube insertions using the Rapid Upper Limb Assessment (RULA). Follow-up surveys were sent to all participating surgeons to determine the prevalence of musculoskeletal pain and formal ergonomic training. Results Zero percent (N = 0/275) of intraoperative observations were found to have a negligible level of ergonomic risk, with 47% low risk, 37% high risk, and 16% very high risk. Tympanostomy tube insertions conferred less risk than tonsillectomy and adenoidectomy, while the use of headlamp or loupes conferred increased risk. Eighty percent of respondents reported having musculoskeletal pain and 40% reported experiencing pain while operating within the past year. The most common area of pain was the cervical spine. No surgeons reported formal ergonomic training. Conclusions Our study demonstrates an unacceptable level of ergonomic risk for common procedures in otolaryngology. Furthermore, most participants reported experiencing musculoskeletal pain despite the duration of examined procedures being relatively short. The high prevalence of work-related musculoskeletal pain and the lack of ergonomic training in our cohort highlight the need for increased awareness of ergonomics as well as the development of formal ergonomic curricula.

Abstract (sommario):
The Human Factors and Ergonomics Laboratory (HFEL) at the Johnson Space Center conducted an ergonomic evaluation of the General Purpose Workstation (GPWS), a glovebox-type workstation flown on one of the Spacelab Life Sciences missions. The HFEL study consisted of: (1) Crew evaluations via pre-flight, in-flight questionnaire and structured post-flight interview, and (2) Video analysis. Findings indicate that the workstation design was acceptable for performing dissection tasks. The crew reported that the task distribution between operators was completely acceptable. Based on the video analysis and the crew comments, the glove interface was found to be critical for crew comfort. A follow-up evaluation is planned for an upcoming mission to evaluate a materials science glovebox and the design impact on posture. Additional microgravity evaluations are planned to obtain objective data on postural changes while working at different gloveboxes.

"Ergonomic Evaluation of Different Surgeon Positions for Total Knee Arthroplasty Surgery". Applied Sciences 13, n. 21 (30 ottobre 2023): 11842. http://dx.doi.org/10.3390/app132111842.
Abstract (sommario):
Ergonomics and risk factors for work-related musculoskeletal disorders have been studied extensively in various industry fields. However, only a few decades ago, these issues became a concern in the healthcare sector. Total knee arthroplasty (TKA) is one of the most common procedures performed by orthopaedic surgeons, and it would be desirable to perform it with an ergonomically safer technique. This study evaluated the ergonomic risk of different surgeon positions when performing contralateral TKA using the dominant hand. After the authors defined the four possible surgeon positions according to the most common positions used by surgeons in our environment (position A, on the opposite side of the knee to be operated on; position B, on the same side as the knee to be operated on; position C, with the patient’s legs separated and the surgeon standing between them; and position D, facing the knee to be operated on, at the patient’s feet), we performed an ergonomic analysis using the Rapid Entire Body Assessment (REBA) method. The overall REBA scores (lower score values indicate better ergonomics than higher) were between 7 and 6.5 for position A, between 6.17 and 5.5 for position B, between 5.92 and 5.5 for position C, and between 3.75 and 3.42 for position D. The test–retest and inter-rater reliability values ranged from substantial agreement to almost perfect agreement. Based on the results, we can conclude that the most ergonomic position for a right-handed surgeon to perform a left TKA is facing the left knee, at the patient’s feet (position D).

Abstract (sommario):
Recently Work-Related Musculoskeletal Disorders (WMSD) and Fatigue are taking on an important role especially in the progressive increase and tightening of the human-machine interface. Many ergonomists are currently using surface electromyographic (sEMG) signals techniques to investigate and assess muscle fatigue. Therefore, this paper provides a narrative review of current research on sEMG techniques in the field of human factors and ergonomic muscle fatigue.Evaluate and summarize studies related to the use of sEMG in human factors and ergonomics to probe muscle fatigue.Selected articles included publications in journals, books, and conference proceedings between 2012 and 2022 and assessed muscle activity in research using surface EMG techniques, intervention studies in real human subjects, quantitative research methods and evaluation tools, and authoritative study design.The final review included 32 articles and found that surface EMG studies in the field of human factors and ergonomic muscle fatigue mainly included risk assessment of work-related musculoskeletal disorders, workplace layout design assessment, usability assessment, and exoskeleton optimization assessment. Moreover, the current EMG experiments have significant variability in ideal and realistic conditions, and the lack of standardization of data and methods, which limits the development and application of EMG signals in human factors and ergonomic studies.The findings of this study can help ergonomists to understand the current research progress of sEMG techniques in this field in order to better select suitable, reliable, and accurate methods for human factors and ergonomic muscle fatigue assessment.

Abstract (sommario):
Human-Computer Interaction (HCI) has long been in a relationship with ergonomics, as a user is expected to have a suitable environment to display a good user experience. This study aimed to identify how organizational or employers' ergonomic values and culture influence employees’ choice of organization to work for. A survey questionnaire, containing 30 items with a Likert Scale (Strongly disagree -1 and 5 for strongly agree) was adopted. A total of 300 questionnaires were distributed and a sample of 250 full-time employees from various companies was used. The collected data was analyzed using descriptive means and correlation via SPSS.21. Results show that a significant dependent relationship exists between employee values and the organization’s ergonomic values (r=0.947; p<0.01), and between employee’s values and mean congruence between values (r=0.829; p<0.01). No significant relationship was found between organizational values and mean congruence between values (r=0.096; p>0.05). The findings in this study may provide direction on how organizations should adopt a better ergonomic design approach for mutual benefits with present and prospective employees.

Abstract (sommario):
The authors developed a validated office ergonomics checklist that focused on outcomes instead of workstation features. The workstation is evaluated primarily through observed working postures and movement patterns while the subject performs their usual tasks. A guidebook for the improvement of computer workstations is keyed to the checklist, to lead the user in reducing risk factors and improving workstation ergonomics. The checklist was first validated in a field test with three expert evaluators. The checklist and guidebook were later tested with a large employer and used as a self-evaluation instrument, by a co-worker, and by an Ergonomics Coordinator with training and experience. Workstations were evaluated by an independent ergonomist before and after interventions were made. Results indicated that the checklist and guidebook were effective in making significant improvements in workstation conditions when administered by an Ergonomics Coordinator, but not when used as a self-assessment or by an untrained co-worker.

Abstract (sommario):
Musculoskeletal disorders often occur in non-ergonomic work postures. The research was conducted in the process of installing an air cleaner workstation for the excavator’s assembly at a heavy equipment manufacturing company. In the installation process, the operator must lift, hold and install the component with weight 12 kg, using the limbs manually without any tools. The objective of this study is to conduct an ergonomic evaluation by assessing the risk of musculoskeletal disorders and provide recommendations for improvement in order to reduce operator musculoskeletal injuries. To determine the level of risk of the job will be used the Rapid Entire Body Assessment method. The results of this study are R.E.B.A scores obtained which is 11, with a very high level of risk, and must be immediately corrected. Ergonomic intervention as a recommendation for improvements that support the work of the operator, is making jigs to help the installation process. After implementation, the REBA score dropped to 3 or decreases by around 67% from the initial risk

Abstract (sommario):
BACKGROUND: The COVID-19 pandemic caused a rapid adaptation of online education, requiring university students to complete their schoolwork remotely. There is a gap in the evidence-based literature regarding these novel home workstations and the potential to help students understand ergonomics and adjust their workstations. OBJECTIVES: We aimed to determine if a remote ergonomics intervention would encourage students to make improvements to their workstation and increase their knowledge of ergonomics. METHODS: Participants completed an ergonomics quiz, workstation evaluation, activity time log, and photographs of their workstation. There were three randomly assigned groups, the control group of 26 participants and the first and second intervention groups with 25 participants each. The first and second intervention groups received information sheets regarding proper workstations. The second intervention group was also required to participate in an ergonomics workshop. Six weeks after receiving the interventions, the control group and two intervention groups completed the materials once again. Eight participants from the control group, 12 from the information intervention group, and 14 from the participatory intervention group completed the study. RESULTS: One-way ANOVA tests between the three groups suggest there was no significant difference in ergonomic knowledge or changes made to workstations. However, the remote participatory ergonomics group increased their level of knowledge about ergonomics. CONCLUSIONS: An ergonomics intervention did not impact one group to change their workstation more than others in six weeks. Future studies on this topic should be conducted over a longer amount of time and with more participants to allow for more opportunities for behavior and workstation changes.

Abstract (sommario):
Dental ergonomics provides an overview of dentists’ work efficiency. The objective of this study was to obtain quantitative information and produce a visualization of the network of scientific publications on the topic of ergonomics and dentistry using bibliometric analysis. Data mining was conducted using the Scopus database and Boolean expressions (ergonom* AND dentist*) on 14 April 2023. Data extraction and analysis were performed using Open Refine version 3.5.2., VOSviewer version 1.6.17., VOSviewer thesaurus, Microsoft Excel, and Tableau Professional version 2020.1.2. A total of 682 documents were identified, with the United States having the largest number of documents and citations (89 documents, 1321 citations). Work, Dentistry Today, and the International Journal of Environmental Research and Public Health were the top three sources. Ergonomics and musculoskeletal disorders (MSDs) are two of the very prominent keywords, with research topics covering prevalence, causes, factors related to causes, prevention, assessment, rehabilitation, evaluation, and intervention. There was no research on ergonomic interventions that collaborated with human factors and ergonomics (HFE). We conclude that the trending topic of dental ergonomics research topics around the world is centered on MSDs. The future research challenge is to apply HFE science to improve the health, safety, efficiency, and quality of dentists’ work.

Abstract (sommario):
The demand for tunnel construction continues to grow by leaps and bounds. Therefore, tunnel mechanization construction is receiving more and more attention for improving excavation ergonomics. To enhance the scientific and comprehensive evaluation results of tunnel drilling and blasting method excavation ergonomics, a set of evaluation methods of tunnel drilling and blasting method excavation ergonomics based on the game theory G2-EW-TOPSIS model is proposed. From the three dimensions of drilling efficiency, construction process duration, and synergistic influence factors, a tunnel drilling and blasting construction ergonomics evaluation index system consisting of 11 indicators such as perimeter hole drilling efficiency, drilling duration, construction quality, and comprehensive cost is constructed. The subjective and objective weights of evaluation indicators are calculated by using the improved sequential relationship analysis method (G2 method) and entropy weight method, respectively, and the combination weights are carried out by using game theory method (GTM) with the Nash equilibrium as the goal. The indices are classified into five grades: excellent (I), good (II), average (III), rather poor (IV), and poor (V), according to the daily tunnel construction. The excavation ergonomics index to be evaluated is calculated using the combined weights, and the comprehensive evaluation index of excavation ergonomics to be evaluated is calculated using the technique for order preference by similarity to an ideal solution (TOPSIS). The proposed rating model was used to analyze the excavation ergonomics of the Shangtianling Tunnel in the Chizhou–Huangshan High-Speed Railway using jumbo drills (JD) and drilling machines (DM) in large- and small-mileage construction, respectively, and to obtain the excavation ergonomics rating and comprehensive evaluation rating of each evaluation object. The research results show that the established excavation ergonomics evaluation model can effectively identify the main factors affecting the excavation ergonomics of the drill and blast method, and has a certain reference value.

Abstract (sommario):
Work-related musculoskeletal disorders (MSDs) accounted for 32% of days-away-from-work cases in private industry in 2016. Several factors have been associated with MSDs, such as repetitive motion, excessive force, awkward and/or sustained postures, and prolonged sitting and standing, all of which are required in farm workers’ labor. While numerous epidemiological studies on the prevention of MSDs in agriculture have been conducted, an ergonomics evaluation of blueberry harvesting has not yet been systematically performed. The purpose of this study was to investigate the risk factors of MSDs for several types of blueberry harvesting (hand harvesting, semi-mechanical harvesting with hand-held shakers, and over-the-row machines) in terms of workers’ postural loads and self-reported discomfort using ergonomics intervention techniques. Five field studies in the western region of the United States between 2017 and 2018 were conducted using the Borg CR10 scale, electromyography (EMG), Rapid Upper Limb Assessment (RULA), the Cumulative Trauma Disorders (CTD) index, and the NIOSH (National Institute for Occupational Safety and Health) lifting equation. In evaluating the workloads of picking and moving blueberries by hand, semi-mechanical harvesting with hand-held shakers, and completely mechanized harvesting, only EMG and the NIOSH lifting equation were used, as labor for this system is limited to loading empty lugs and unloading full lugs. Based on the results, we conclude that working on the fully mechanized harvester would be the best approach to minimizing worker loading and fatigue. This is because the total component ratio of postures in hand harvesting with a RULA score equal to or greater than 5 was 69%, indicating that more than half of the postures were high risk for shoulder pain. For the semi-mechanical harvesting, the biggest problem with the shakers is the vibration, which can cause fatigue and various risks to workers, especially in the upper limbs. However, it would be challenging for small- and medium-sized blueberry farms to purchase automated harvesters due to their high cost. Thus, collaborative efforts among health and safety professionals, engineers, social scientists, and ergonomists are needed to provide effective ergonomic interventions.

Abstract (sommario):
AbstractIn user-centred design, digital human models hold the potential for proactive evaluations of ergonomics or discomfort in terms of a computer aided ergonomics tool. Therefore, models predicting human interaction behaviour, are necessary. In this contribution we present such a model as well as its initial evaluation. The evaluation is performed by applying the interaction model to a specific use case, conducting a comparison with an empirical subject study. The evaluation shows that similar and realistic human behaviour was predicted, which was consistent in terms of whole-body strain.

Abstract (sommario):
Summary This article discusses the importance of job analysis tools for training in the context of participatory ergonomic processes. It explains the major principles and challenges in the design of these tools for short-cycle repetitive tasks and for long-cycle varied tasks. The intervention framework is described and the proposed tools are presented and related to the literature. The participants’ difficulties with the tools developed in both contexts studied are summarized. The discussion suggests that these difficulties are partly related to the company context and raises questions about the data relevant for the evaluation of solutions in the case of non-repetitive tasks.

Abstract (sommario):
This study evaluated the knowledge and application of ergonomic principles as well as manifestation of pain by dental students at the Federal University of Maranhão. Forty-four students answered a questionnaire on ergonomic principles. Photographs of the clinical rounds were performed to evaluate the postures adopted, without the students knowing the moment of photographic registration, avoiding that they modified their posture. The relationship between theoretical knowledge and the applicability of ergonomics in dental setting was evaluated. Data were analyzed using descriptive statistics. The Chi-square test analyzed the distribution of categorical variables among the evaluation instruments (α = 5%). Most of the participants adopted a satisfactory posture and presented knowledge about ergonomic postures, however, one can observe the poor positioning of the eyes and spine. 75% of the patients experienced pain in the body, being the spine (61.4%) and neck (40.9%) the most affected sites. The sample evaluated had good knowledge on ergonomic principles, but these were not adopted entirety, which may have led to the onset of pain.

Abstract (sommario):
Intisari— Perusahaan manufaktur merupakan perusahaan yang memproduksi bahan mentah atau bahan baku menjadi barang jadi, dengan menggunakan alat, mesin, maupun dengan bantuan tenaga manusia. Perusahaan manufaktur ergonomi dan antropometri sangat dibutuhkan. PT PO sendiri merupakan perusahaan internasional pembuatan produk pemantauan korosi pipa internal dan menyediakan layanan yang berkaitan dengan pengelolaan data lapangan kehilangan logam pipa, atau biasa disebut sebagai perusahaan “Corrosion Monitoring System (CMD)”. Perusahaan manufaktur tidak lepas dengan adanya kegiatan manual material handling, hal ini dapat menyebabkan masalah kesehatan kerja khususnya cidera MSDs. PT PO yang memiliki permasalahan tidak ergonomisnya posisi kerja pada area support sandblasting dimana terdapat keluhan nyeri pada bagian tubuh pekerja. Antropometri sendiri merupakan studi yang berkaitan dengan postur tubuh manusia dan juga desain alat bantu yang dipakai manusia. Metode PEI ini bertujuan untuk menghitung posisi pekerja apakah sudah ergonomis atau belum, jika posisi tidak ergonomis maka akan dilakukan perbaikan pada posisi kerja dengan mendesain alat bantunya. Hasil dari penggunakaan metode PEI pada permasalahan yang ada pada PT PO setelah melakukan perbaikan meja kerja sebesar 1.105, juga menghasilkan waktu kerja yang lebih efektif dan efisien dengan masing-masing membutuhkan waktu 269 x 10-4 menit dan 554 x 10-4 menit dalam satu produk untuk membersihkan dan menyuci produk DBB (Double Block & Bleed). Diharapkan perusahaan harus lebih memperhatikan posisi para pekerja, khususnya adalah pada area support sandblasting karena pada area tersebut posisi pekerja yang paling tidak ergonomis, sehingga pekerja pada area tersebut lebih sering dan lebih cepat mengalami kelelahan kerja.
Abstract— Manufacturing companies are companies that produce raw materials or raw materials into finished goods, using tools, machines, or with the help of human labor. Ergonomics and anthropometric manufacturing companies are in demand. PT PO itself is an international company manufacturing internal pipe corrosion monitoring products and providing services related to field data management of pipe metal loss, or commonly referred to as a “Corrosion Monitoring System (CMD)” company. Manufacturing companies are not separated from the manual material handling activities, this can cause occupational health problems, especially MSDs injuries. PT PO which has problems of unergonomisnya working position in the sandblasting support area where there are complaints of pain in the body of workers. Anthropometry itself is a study related to the posture of the human body and also the design of tools used by humans. This PEI method aims to calculate the position of the worker whether it is ergonomic or not, if the position is not ergonomic then there will be improvements in the work position by designing the tool. The results of the use of PEI method on the existing problems at PT PO after repairing the workbench of 1,105, also produces a more effective and efficient working time with each takes 269 x 10-4 minutes and 554 x 10-4 minutes in one product to clean and wash the product DBB (Double Block & Bleed). It is expected that companies should pay more attention to the position of workers, especially in the sandblasting support area because in that area the position of workers is not the most ergonomic. so that workers in these areas more often and more quickly experience work fatigue.

Abstract (sommario):
Concerning occupational safety, the aim of ergonomics as a scientific discipline is to study and adjust working conditions, worker equipment, and work processes from a psychological, physiological, and anatomical aspect instead of adapting the worker to the needs of the job. This paper will discuss and analyze the potential of the garment-embedded body posture tracking sensor and its usage as standard working equipment, which is meant to help correct improper and high-risk upper body positions during prolonged and static work activities. The analysis evaluation cross-reference is based on the Rapid Upper Limb Assessment ergonomics risk assessment tool. Signals generated by the wearable are meant to help the wearer and observer promptly-continuously detect and correct bad posture. The results show a positive progression of workers’ body posture to reduce the ergonomic risks this research covers. It can be concluded that wearable technology and sensors would significantly contribute to the observer as the evaluation tool and the wearer to spot the risk factors promptly and self-correct them independently. This feature would help workers learn and improve the correct habits of correcting ergonomically incorrect body postures when performing work tasks.

Abstract (sommario):
The objective of this work was to evaluate farming machines adapted to forestry work and to verify if their characteristics meet the safety, ergonomics and working conditions necessary to maintain the health and safety of the operators. Thus, three farming tractors were selected, with a closed cabin and a minimum power of 73.5 kW, a widely used specification in the forestry sector. The following ergonomic parameters were considered: acess to the cab, cab dimensions, visibility, seat, controls and operation, work posture, cabin air conditioning, noise, lighting and maintenance aspects. The evaluations were based on the guidelines contained in the “Ergonomic Guidelines for Forest Machines” of the Swedish Forestry Research Institute, developed for forestry machines. The results showed that all the evaluated machines presented ergonomic standards below those indicated in all evaluated aspects, particularly related to access to the work station and difficulties during mechanical maintenance, besides the necessity of adopting forced postures during the working day due to operator’s seats. It was concluded that the farming machines adapted for work in forest processes presented significant gaps in relation to the ergonomic aspects, which represents high and imminent risks of development of occupational diseases in their operators, as well as the predisposition to work accidents.

Abstract (sommario):
Annotation. Work ergonomics is a fundamental factor in the high-quality and successful daily work of dentists. Non-observance of the basic aspects of ergonomics leads to the deterioration of treatment results, an increase in the number of complications, an increase in energy and time spent on the treatment, and the occurrence of violations in the physical and psycho-emotional health of the doctor. The purpose of the work is to optimize the ergonomic work patterns of dentists by developing an algorithm for individualized correction of the ergonomic component of work using the possibilities of modelling the spatial relationships of the components in the projection of the working field and considering the topographic affiliation of different groups of teeth. 20 dentists and 12 interns participated in the study, from which two groups were formed – the research group and the control group. The ergonomic components of the work of dentists were evaluated according to the Rapid Entire Body Assessment (REBA) and Rapid Upper Limb Assessment (RULA) criteria. Mathematical analysis and verification of the reliability of the results, as well as the calculation of possible errors, were carried out on the basis of the software “Statistica 6.0” (STATISTICA) and Microsoft Office Excel 2007 (Microsoft Office). Based on the results of the study, a discrete-event simulation of the work cycle of endodontic treatment was carried out, after which an individualized protocol for optimizing the ergonomic components of each doctor's work was formed. As a result of the study, an evaluation of the effectiveness of using the developed ergonomics correction algorithm in the practice of doctors during root canal treatment and an analysis of changes in the structure of the distribution of errors and complications under the conditions of optimization of ergonomic components in accordance with adapted recommendations was carried out. Statistical interdependencies between ergonomic factors and treatment complications were revealed. The implementation of individualized protocols for the correction of ergonomic components in the process of endodontic treatment helps to reduce the frequency of errors and complications.

Abstract (sommario):
The aim of the presented work is to analyze the ergonomics-related disorders in online education using the fuzzy AHP approach. A group dialogue with online education academicians, online education students, biotechnologists, and sedentary computer users has been performed to spot ergonomics-related disorders in online education. Totally eight ergonomics-related disorders in online education have been identified, and the weight of each disorder has been computed with triangle-shaped fuzzy numbers in pairwise comparison. Furthermore, the ergonomics-related disorders in online education are kept in four major categories such as afflictive disorders, specific disorders, psychosocial disorders, and chronic disorders. These four categories of ergonomics-related disorders in online education are evaluated and compared using fuzzy analytical hierarchical process methodology to get ranked in terms of priorities. The results may be instrumental for taking appropriate corrective actions to prevent ergonomics-related disorders.
