Anxiety is a state of mind and a physiological response of the person when facing a situation that causes anguish, fear and mental and emotional blockage. Among young university students, this occurs to a greater or lesser degree and is often not diagnosed or evaluated in its true magnitude. The Covid 19 pandemic has generated a radical change in the teaching modality that has gone to a virtual learning, which has aggravated the usual anxiety levels in students. The aim of this study was to examine the anxiety level of industrial engineering students of different academic levels, in this pandemic environment, to help them cope with this problem. To do this, a study sample was taken and an evaluation instrument was applied that allowed these levels to be established. Relationships were established with the number of credits taken on average and the study cycle of the students in the sample. The results show significant information that can help academic leaders and students themselves to take measures that help improve their anxiety levels.","PeriodicalId":130337,"journal":{"name":"Physical Ergonomics and Human Factors","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125055947","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The prolonged physical stress increases total cortisol concentration. Anecdotal data suggests that using graded compression sleeves forearm alleviates pain in the upper and lower limbs. The physiological mechanisms underlying these benefits are not fully understood. This study aimed to assess the effects of wearing graded compression (13-18 mmHg) sleeves on circulating cortisol after completing a physical activity with three different intensities. The study included six participants between 18 and 25 years old without a known history of injuries in the upper limbs. The proper sleeve size was fitted to the participants following the manufacturer’s instructions (On-Site Therapy, Tallahassee,FL.), and anthropometric measurements were taken. All the participants randomly completed a cycle hand ergometer exercise at 60 RPM at 25 W., 50 W., and 75 W for a maximum of 10 minutes with and without forearm sleeves. All the participants rested for at least 72 hours before the next exercise session to avoid muscular fatigue. Venous blood samples were drawn before and after completing each session to compare the effects of wearing graded compression sleeves on the circulating cortisol concentration. Cortisol concentrations were analyzed by enzyme link immunosorbent assay (ELISA). A Linear mixed-effects model was used for analysis. Participants wearing the compression sleeves showed a significant decrease in cortisol concentration at 50 W only. This study shows the potential benefits of wearing compression sleeves while performing activities involving the upper limbs. Even though our results show a decrease in cortisol concentration at 50 W., a larger sample size would be needed to dictate a significant difference in the physiological response associated with the use of graded compression sleeves.","PeriodicalId":130337,"journal":{"name":"Physical Ergonomics and Human Factors","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129233402","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Keyson","doi":"10.54941/ahfe1002600","DOIUrl":"https://doi.org/10.54941/ahfe1002600","url":null,"abstract":"Whether it is from the office-office or the home office, creating a physical work environment is essential for both improving work performance as well as for the physical and mental wellbeing of employees. But as jobs are becoming increasingly less active, and working adults are spending almost a third of their lives in the office, most of their time is now spent sitting behind a desk. This time in sedentary behavior is increasing rapidly on a global scale and has become a great area of concern, as research has proven that this behavior is linked to an increase in all-cause mortality. To reduce the sedentary nature of the workplace, many companies are now replacing the standard desk with sit-stand desks (SSDs). SSDs are height adjustable desks that allow the user to work in either a sitting position or a standing position. Unfortunately, even as more companies are implementing these desks in their workspace, many studies indicate that there is a lack of utilization among working adults, with many only transitioning the desks to a standing position once a month or less.This paper presents a user-centered design project examining how to reduce the long-term sedentary behavior of desk-based working adults by motivating them to utilize their SSDs to make more transitions between sitting and standing. The project involved an agile design approach based on a cyclic process where a range of design techniques and research methods were used to look deeper into the practices and habits of working adults and better understand why this lack of use occurs and how it can be changed. These design techniques and research methods include a literature study, auto-ethnographical research, and 11 interviews with both active and non-active SSD users. An analysis of the differences between active and non-active users,led to the hypothesis that to reduce the SB of desk-based working adults, the use of SSDs in the workplace should be normalized by ensuring that working adults understand the benefits and proper use of SSDs while also offering the key tools: (1) reminders of when to transiting between sitting & standing; (2) social support; (3) awareness of effects on body & mind ; (4) task-based transitions. . This hypothesis was then used to initiate an empirical research through design process. Through this process, the final concept, BMDesk Application and Controller, was created. The BMDesk showcases an interactive digital platform and controller which utilizes the previously defined design opportunities to aid desk-based working adults in becoming more in tune with their physical and mental state while also providing them with the support they need to reduce their long-term sedentary behavior by utilizing their SSDs. The platform provides the user with an interactive tool that (1) gives them control over setting up their workday and defining how many sit-stand transitions they want to make and how long they want to remain in each position; (2) triggers a light remin","PeriodicalId":130337,"journal":{"name":"Physical Ergonomics and Human Factors","volume":"121 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128335158","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The lower longitudinal arch is an intrinsic factor related to the lateral drift of the hallux. This paper conducted a quantitative study on the improvement of the first metatarsal and arch condition by arch support and used finite element analysis to simulate the bone displacement with the intervention of arch support. In this research, a foot arch support made of carbon fiber was developed and seventy-six female subjects were recruited for a two-month wear trial. Footprints of their dominant foot were measured to investigate the effect of the arch support on lifting the arch and correcting the hallux valgus pathology. Different foot parameters including foot length, foot breadth, heel breadth, arch angle, arch breadth, plantar arch index, foot type index, and hallux valgus angle were also compared. By using finite element analysis, the biomechanical effects of the arch support on the foot structure can be visualized. According to the results of the wear trial, the use of the arch support can significantly improve the arch curvature of the foot, while no significant correction of the hallux valgus angle was found. Among the arch parameters, the arch breadth and the foot type index are the key indicators to precisely characterize foot types and arch conditions. When a clear outline of the footprint is not available, arch breadth provides reliable association with the foot type index (R2 = 0.928). An arch breadth ≥ 4 cm is categorized as flatfoot. This article confirms the effectiveness of our arch support in lifting the arch over a two-month period and provides a scientific surrogate index to aid in diagnosis, which is important for therapeutic and diagnostic applications.","PeriodicalId":130337,"journal":{"name":"Physical Ergonomics and Human Factors","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133007175","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Xiong","doi":"10.54941/ahfe1002592","DOIUrl":"https://doi.org/10.54941/ahfe1002592","url":null,"abstract":"Background and Objective: Although the role of shoes on sports performance and injury has been extensively examined, only a few studies investigated the effects from insoles. Recent studies on carbon fiber insoles (CFI) on athletic performance reported that CFI could improve sports performance by reducing energy loss and increasing energy return. However, there are scarce reports on the effects of CFI on muscle fatigue and wearing comfort. While stiffer CFI insoles are superior in energy loss reduction and energy return, they could increase more muscle activation to absorb the shock or provide more propulsive force to push CFI, leading to increased muscle fatigue and discomfort. Therefore, this study aims to evaluate the effect of CFI on lower-extremity muscle activation and wearing comfort during treadmill running. Methods: Three types of insoles were compared, namely CFI, CFI with cushioning (CFIC), and a benchmark commercial insole (COM). Fifteen healthy young men participated in the experiment. Each participant wore the same sports shoe, three different insoles in a random order, and ran on a treadmill at a speed of 10 km/h for 5 minutes. Surface electromyography signals of four lower-extremity muscles (Rectus femoris, Tibialis anterior, Biceps femoris, and Gastrocnemius medialis) were recorded in real-time for measuring muscle activation. After completing a trial run with each experimental insole, the participants provided their subjective ratings on perceived insole stiffness, energy support, overall comfort, and fatigue. Analysis of variance (ANOVA) and post-hoc grouping analysis were conducted to statistically evaluate the effects from three different insoles. Paired t-test was performed to compare CFI and CFIC and explore any cushioning effect. Results: In terms of lower-extremity muscle activation, even though CFIC and COM showed no significant difference for all four lower-extremity muscles, CFI induced a marginally significant increase of 1.5% on Gastrocnemius medialis (p = 0.063) and a significant reduction of 0.7% on rectus femoris (p=0.011) than COM. For the subjective ratings, both CFI and CFIC were significantly stiffer than COM (p < 0.001), but there were no significant differences in overall comfort, energy support, and fatigue. Compared with CFI, CFIC significantly reduced Gastrocnemius medialis muscle usage by 2.1% (p = 0.012) and was marginally less stiff (p = 0.102).Conclusions: This preliminary study showed that the carbon fiber insole CFI induced higher calf muscle usage and was perceived to be stiffer during treadmill running, which could contribute to provide the propulsive force for better sports performance. Carbon fiber insole with cushioning (CFIC) can help to relieve muscular fatigue. Further research should be conducted to examine the carbon insole effects on sports performance and long-term muscle activation and perceived feelings.","PeriodicalId":130337,"journal":{"name":"Physical Ergonomics and Human Factors","volume":"409 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133727174","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Dominated by metallic blue and grey, the train body is made of stainless steel with an empty weight per train reaching 31 to 35 tons. PT MRT Jakarta provides 16 train series (one series consists of six trains) so that the carrying capacity of one series reaches 1,950 people per series. The train’s interior is equipped with air conditioning, two CCTVs, hand straps, priority seats and a particular wheelchair area. Seats are made of fibre reinforced plastic (FRP) which is fire resistant with a width of 43 cm x 42 cm. This study aims to analyse the passenger posture by the Reba method with the results of measurements obtained in section a, namely 6, section b is 5, and the meeting point between parts a and b is 8. That is, the results of the Reba score have a high level of risk with immediate action needed. From the results of calculations, it is found that the sitting position of the MRT passenger is not ergonomic. Therefore, the authors analysed the posture of the passengers of the Jakarta MRT passenger with the Reba method to provide suggestions for improving posture and seats.","PeriodicalId":130337,"journal":{"name":"Physical Ergonomics and Human Factors","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134190809","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This thecnique applied during positioning and handling presupposes, on the one hand, respect for the functional anatomy of the patient and, on the other hand, the protection of the operator performing the handling.Kinaesthetic can contribute significantly to reducee biomechanical load and to improve healthcare outcomes.By using an optoelectronic system (SMART-DX 6000 System, BTS, Milan, Italy) and 6 spherical reflective markers placed at selected landmarks (c7, bilaterally scapular acromion, sacrum, bilaterally anterior superior iliac spine (Davis, 1991)), the trunk kinematics of a worker was recorded during several patient handling tasks (lateral decubitus, sitted placement, lateral shift, side displacement, downward displacement) with (CNSTTC) and without (CTRL) kinaesthetic. Then, the ranges of motion (RoM) of the trunk in the three planes of space were calculated. Muscular activity coactivity was also recorded through sEMG from the following muscle bilaterally: Erector Spinae, Rectus Abdominis, Rectus Femoris, Biceps Femoris, Anterior Tibialis and Gastrocnemius Medialis. The co-activation index is a parameter that provides the percentage of simultaneous activation during each task of the antagonist muscles of the trunk and leg. It has been shown in previous literature studies how increased co-activation can be disadvantageous for the jointsThe most relevant kinematic results are in the trunk. Trunk flexion is reduced in all the analyzed tasks when using kinaesthetic approach. Otherwise kinematics results showed increased values of RoM for trunk lateral bending in all tasks but sitted placement.About sEMG results showed a decreased co-activation of the trunk muscles in lateral decubitus, sitted placement and side placement. Co-activazion of the legs showed decreased values for lateral shift,, side placement and downward displacement. was substantially unaffected except for lateral decubitus where kinaesthetic showed an increased value of coactivation.These are preliminar results that should be confirmed with a larger sample of experienced workers. Moreover it could be advisable to identify some sub-tasks from each subtasks that might be more noticeable from an ergonomic point of view.","PeriodicalId":130337,"journal":{"name":"Physical Ergonomics and Human Factors","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116020497","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite high back pain prevalence in this sector manual material handling (MMH), instead, seems almost ignored. The aim of our study is MMH risk assessment in a fruit and vegetable department of a supermarket. This task wasn't still investigated, to date, together with standardized protocols and instru-mental-based tools. The sizes of the shelf allowed the use of the NIOSH protocol for the low level, whereas middle and high did not allow its use due to horizontal distance that exceeded the 63 cm set by the protocol. To integrate the NIOSH pro-tocol was used surface electromyography (sEMG). The recommended weight limit (RWL) in our case, according through NIOSH liftinq equation, was 17 Kg. The maximum handled weight from the workers was 14 Kg. The maximum mean peak value while lifting 14 Kg at a low level was 40.1% of Maximum Voluntary Contraction (MVC) in the left Erector Spinae. We assumed this sEMG value to be a safety value and used as a limit for lifts at the middle and high shelf levels because the maximum handled weight of 14 Kg was lower than the 17 Kg limit calculated through the NIOSH equation for the low level. This sEMG limit was exceeded, in the middle, while lifting 14 Kg (47.8% MVC), and in the high level lifting 10 Kg (44.7% MVC), 12 Kg (50.3% MVC), and 14 Kg (57.7% MVC). Our findings show that, for the analyzed shelf and for the male working popula-tion of that supermarket, we could accept as reasonably safe handling boxes up to 14 Kg for the low level, up to 12 Kg in the middle, and up to 8 Kg in high. This study shows that the integration of different assessment tools, such sEMG and NIOSH protocol, could help to a better estimation of biomechanical risk assess-ment.

{"title":"Influence of the shape of a forearm support on the range of pronation and supination in the context of a surgical arm assistance system","authors":"Ferdinand Langer, T. Maier","doi":"10.54941/ahfe1003039","DOIUrl":"https://doi.org/10.54941/ahfe1003039","url":null,"abstract":"Surgery often results in static, uncomfortable arm and upper body postures, which lead to high stress on the surgeons' upper extremities [Szeto 2012]. To counteract this, an interaction-based arm assistance system has been developed to physically unload the surgeon's upper extremities during laparoscopic procedures. This is achieved by actively supporting the forearms. Thereby, a supporting force acts on the forearms, which follows the natural forearm movements without restrictions [Karlovic 2015]. The assistance system is controlled exclusively by a form fit and frictional connection of the forearms with the arm support. Investigations show an influence of the anthropomorphic shape of the form on objective and subjective operability and an advantage of the anthropomorphic shape over no support and a flat form [Langer 2022]. In this study (funded by the German Research Foundation), the range of pronation und supination within anthropomorphic forms is investigated to design the human-machine interface of the arm assistance system for precise surgical tasks with forearm rotation. Within the scope of this research project, the interface parameter shape of the forearm support is therefore investigated on the basis of five shape variants (gender-specific negative shapes of 05-, 25-, 50-, 75- and 95-percentile adults). To investigate the range of motion of pronation and supination, the 32 subjects grasp a round handle, which is oriented orthogonally to the ground (start position). The forearm is bent 90° to the upper arm (flexion). On instruction, the subjects rotate their forearm maximally in the pronation direction and then in the supination direction. The maximum angles achieved in each case are measured starting from the start position. The subjects then rate the comfort and further properties of the shape on a 7-point Likert scale. This is repeated with all shape percentiles. The study shows that the percentile of the anthropomorphic form has an influence on the range of motion in pronation and supination of the forearm. Compared to no support of the forearm (Ø-pronation = 76.4°, Ø-supination = 114.3°), the average range of motion for support with the 05-percentile form (smallest shape) decreases by 8.4% (70.6°) for pronation and by 22.5% (93.3°) for supination. In contrast, the average range of motion for support with the 95-percentile form decreases by 5.3% for pronation and 18.1% for supination. For pronation and supination, the trend shows that the smaller the shape of the forearm support, the smaller the average range of motion. The average range of rotation that can be achieved without support and without form is not achieved with any form. The subjective survey shows that comfort is lowest for the smallest form. Furthermore, the correlation of the range of motion of the different forms is evaluated depending on the forearm percentile of the subjects. Design recommendations for the shape of the forearm support are derived from the results.
