Specifically, hypoxia may affect the neural function of the brain, leading to severe cognitive deficits and a significant decline in memory function and attention. This article addresses the effect of human factors on transportation design and operation at high altitudes (HA), with some details on the Tibet-China region. Specifically, the paper first reviews the basic transportation-related concepts for high altitude, including oxygen and temperature levels, driver perception-reaction time, hazard perception, vehicle speed, and walking speed. Then, the transportation users affected by high altitudes are discussed, including drivers, pedestrians, cyclists, passengers, and others. Next, the impacts of human factors on highway design and operation for HA regions are discussed along with the research needs. Finally, recent innovations to address the challenges of HA transportation are presented, along with case studies comparing some human factors of the plateau and plain areas.

Therefore, this study was conducted to determine the prevalence of MSDs among midwives and to examine the relationship between job stress and the prevalence of MSDs in different regions their body. This was descriptiveanalytical and cross-sectional study. The study population included all midwives working in public and private hospitals of Kerman in 2019. According to the research community, 74 midwives were selected as a sample of research, by Census method. For data collection, Standard Nordic Musculoskeletal Questionnaire (NMQ) and Altmeyer job stress questionnaire were used. The data were analyzed with descriptive and analytical statistics (Pearson correlation, t-test and Chi square test) methods by SPSS 16 software. In this study 78.4 % of subjects had experienced discomfort or pain in the past 12 months at least in one body part. The most frequent symptoms of MSDs were observed in the three parts of body, feet with a frequency of 39.2% (29 persons), and knees and back each one 35.1% (26 persons). Also in this study, the relationship between musculoskeletal disorders and job stress was dignificant (P<0.05). According to the result of this research, it can be concluded that job stresses can presumably intensify physical side effects including musculoskeletal disorders. Also, the prevalence of musculoskeletal disorders in midwives under studied was high. Therefore, holding training courses about standard body postures while doing job tasks and avoiding inappropriate body posture will be important.","PeriodicalId":92777,"journal":{"name":"Ergonomics international journal","volume":"76 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68920296","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}

However, many people are unsure what role, if any, human drivers will play at these levels. How do these automated features affect drivers' performances? This article attempts to answer this question by reviewing critical information from human-automation system characteristics of vehicles with specific automated features (AV). Essential facts about the differences in functional features between human drivers and systems and automated features at various levels were clarified and summarized, including their characteristics, roles, and technical AV structures. Finally, drivers’ performances at all automation levels were discussed. This review provides the insight needed to understand how the automated features affect drivers' performances and to what extent. The results indicate that drivers’ performance does not improve as the automated level upgrades. Compared with no automation, active-safety and high automation can achieve lower workload and better driving performances for drivers. In contrast, driver assistance and partial/conditional automation impose more increased workloads and unstable (even risky) driving performance.","PeriodicalId":92777,"journal":{"name":"Ergonomics international journal","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68920197","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 aim of this study was to assess how well hospital workers practice proper body mechanics and ergonomics while carrying out their official duties. A descriptive design with sample size of 390 was used and the data was collected using researcher-modified questionnaires. Frequency of each demographic variable across the questions was determined on the average of 57.7% practice of ergonomics and body mechanics by the health workers. Inferential statistics of Chi-square was considered at 0.05 level of significance to determine the relationship between the demographic variables and the questions on practice and analyzed using Statistical Product and Service Solution, version 21. The result showed [“straightening of knees and bending of back when lifting an object from the floor” - marital status (P = 0.025), occupation (P = 0.036) and working years (P = 0.024)], [“using of the principles of body mechanics during the procedure for removing a patient from bed to chair and vice versa” - sex (P = 0.001) and working years (P = 0.000)], [“having seat at work with a forward protrusion at the waist (low back) area” - sex (P = 0.040) and occupation (P = 0.001)], [“standing to carry out one’s duties” - occupation (P = 0.000) and educational qualification (P = 0.002) and [“how long standing on a stretch without sitting down” - occupation (P = 0.000) and working years (P = 0.034)]. Other results are; [“asking for help from a friend when trying to lift big patient or object” - occupation (P = 0.001)], “having work tables close to their chest level when seated” - marital status (P = 0.050)], [“their feet touching the ground when seated” - occupation (P = 0.010)], [“having their seat at work with an arm/ back rest” - working years (P = 0.012)], [“sitting upright to do work” - working years (P = 0.008)], [“often get up from their seats to stretch the legs” - educational qualification (P = 0.001)], [“If need be, their chair/table to be changed to conform to their individual structure” - working years (P = 0.008) and [“the type of foot wear they are often comfortable with” - sex (P =0.006)].

This is a review study. The required information was obtained by searching the International Information Banks of Science Direct, Web of Science, Scopus, Springer, ProQuest, Google Scholar and PubMed (between 1980to2022).

Results: Examples are presented of measurements carried out with digital dynamometers using the original methodology, illustrating advantages and limits. Inter/intra-observer validation tests confirm the advantages of digital over analog dynamometers. Comparisons between measured data and subjective force ratings are presented and confirm good correlations. Conclusion: The results confirm that digital dynamometers, using proposed original methodology, generate more accurate information than analog. The methodology may be useful for future revision of ISO Standard.
