This study conducted a risk assessment of the working posture of informal tailors. The postural risk for upper and lower-limb musculoskeletal disorders for 220 informal tailors was evaluated using the rapid entire body assessment (REBA) method. The prevalence and severity of body part pain were assessed using the Corlett and Bishop body map questionnaire. No tailor had a negligible grand REBA score of 1 or low risk score of 2-3. Analyses showed that the hours worked per day, length of employment as a tailor and elevated grand REBA scores (8-10) were significantly associated with a higher risk for developing musculoskeletal disorders (p < 0.05). Based on the REBA assessments, no tailor had an acceptable action level. The working posture of tailors needs to be immediately changed to reduce the risk of developing musculoskeletal disorders.","PeriodicalId":37855,"journal":{"name":"International Journal of Human Factors and Ergonomics","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1504/ijhfe.2019.102297","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42970987","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}

It was agreed that CRM supported safe flight and mission effectiveness. Interviewees claimed CRM was useful in helping crewmembers navigate traumatic, high-stress incidents such as murders and riots. Interviewees claimed the CRM skillset supported objective analysis of personnel issues, such as overbearing pilots or under-performing TFOs. Some suggested the constituency for CRM training should be expanded to include dispatchers, managers and others connected with the NPAS. As the interviews and flight-deck observations progressed, it emerged that the relationship between the bases and headquarters had become strained, possibly affecting morale. The NPAS must create a trusting, open and inclusive culture in which critique is welcomed and good ideas implemented. The tenets of CRM could inform transformation.","PeriodicalId":37855,"journal":{"name":"International Journal of Human Factors and Ergonomics","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1504/ijhfe.2019.102305","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44286788","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}

Building clearing operations, especially in active shooter scenarios, can be high risk when officers need to clear a building on their own. This study analysed the use of a small drone in a building clearing operation with a County Sheriff's Department to help mitigate the danger of single officer clearing operations. Aspects of trust (human-robotic trust survey), situational awareness (SART), mental demand (NASA-TLX), and performance (completion time and target miss rate) were measured. Fourteen officers, age 22-63 with an average of 5.4 years law enforcement experience and three years of building sweeping experience participated in the study. The results of the study indicate that the use of a single drone during clearing operation can slow down the operation, but accuracy and safety of clearing is enhanced. The use of the drone saw non-significant changes in mental workload other than temporal demand, increased situational awareness, a decrease in the number of targets missed, and a moderate level of trust.","PeriodicalId":37855,"journal":{"name":"International Journal of Human Factors and Ergonomics","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1504/ijhfe.2019.102294","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46906567","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 results showed some improvements in terms of usability and affordance with the second prototype design. Usability was also improved with the first prototype trowel design, although it required higher electromyographic activity levels compared to some other designs. Hand anthropometric measures had no effect on the studied measures. The results suggest that although improving performance and usability may not necessarily be compatible objectives, the idea of cylindrical tool handles with variable cross-section can be employed advantageously to improve the tool's usability. The findings may also rule out the possibility that users' hand anthropometry is always necessary for the design of tool handle. Rather, hand tool designers and manufacturers should pay special attention to the working context and quality of hand-handle interaction to improve the design and usability of hand tools.","PeriodicalId":37855,"journal":{"name":"International Journal of Human Factors and Ergonomics","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43295990","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}

A sample of 150 employees from the state of Qatar was used to test the proposed research model. The antecedent variables considered are attitude, social influence, perceived behavioural control, self-efficacy, facilitation conditions, performance expectancy, effort expectancy, compatibility and management support. The results show that attitude, perceived behavioural control, and social influence have significant positive effects on employees' behavioural intention to apply ergonomics at the workplace. Compatibility and performance expectancy have significant positive indirect effects on behavioural intention through attitude. Additionally, facilitation conditions and self-efficacy have significant positive indirect effects on behavioural intention through perceived behavioural control.

Thirty-two male participants were randomised in a single blinded, cross-over placebo controlled study in which they ingested standardised rooibos or placebo capsules for four weeks prior to a fatiguing elbow flexion/extension exercise test entailing five sets/bouts of 15 repetitions of maximum voluntary contractions separated by 10-second rest intervals on a Biodex System 3 at a speed of 60° per second. Peak torque flexion (Nm) was consistently higher in the rooibos experimental (Re) compared to the placebo control (Pc) across the five exercise bouts, and this performance trend during flexion was also seen in the total work (joules) completed, although not significant (P > 0.05).

The modified Nordic questionnaire is adopted to explore the prevalence of MSDs and associated critical ergonomic risk factors among 181 male foundry workers. Further, logistic regression is applied to explore critical factors causing MSDs in a foundry context. This study investigates manual materials handling (MMH) effect on MSDs prevalence and highlights 'load-handled' as the most critical risk factor. In the process, the study emphasises lower back, neck and knee as the vulnerable body parts. Additionally, it was investigated that workers from melting sections of the foundries are prone to MSDs risks that require immediate intervention. A work system model was used to frame the study and interpreted the results in the context of human-machine interaction occurring at the workspace. The results can be further coupled with engineering interventions for improved productivity in the foundry.","PeriodicalId":37855,"journal":{"name":"International Journal of Human Factors and Ergonomics","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48438453","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}

Principal component analysis (PCA) and factor analysis (FA) are used here. Three principal components were identified which represents 99% of the variance in the whole dataset. Factor analysis is performed on these three principal components to find most important factors based on individual factor loadings.
