Objectives. The present study aimed to review the changes in anthropometric dimensions around the world during the last 30 years.Methods. The search for this study was conducted in four databases with related keywords. Papers from 1990 to 2021 were reviewed and 4139 articles were identified, with 505 related titles. Of these, 187 articles met the eligibility criteria, and their whole text was examined; 132 articles were then included for the final review.Results. The reviewed studies showed that a large number of anthropometric dimensions of the human body have become larger than in the past, such as height. Although the increasing trend of anthropometric dimensions in the past has been faster than in recent years, decreasing changes have also been seen in some anthropometric dimensions, such as the human jaw, face width and head width. It should be noted that the main reasons for the changes mentioned in the studies are economics and family income, social conditions, health and nutrition.Conclusion. Since the process of changes in anthropometric dimensions is not always the same, anthropometric data should be updated regularly, and work environments and equipment should be reviewed or redesigned according to the new anthropometric data.

Objectives. This study examines the role of different machine learning (ML) algorithms to determine which socio-demographic factors and hand-forearm anthropometric dimensions can be used to accurately predict hand function. Methods. The cross-sectional study was conducted with 7119 healthy Iranian participants (3525 males and 3594 females) aged 10-89 years. Seventeen hand-forearm anthropometric dimensions were measured by JEGS digital caliper and a measuring tape. Tip-to-tip, key and three-jaw chuck pinches were measured using a calibrated pinch gauge. Subsequently, 21 features pertinent to socio-demographic factors and hand-forearm anthropometric dimensions were used for classification. Furthermore, 12 well-known classifiers were implemented and evaluated to predict pinches. Results. Among the 21 features considered in this study, hand length, stature, age, thumb length and index finger length were found to be the most relevant and effective components for each of the three pinch predictions. The k-nearest neighbor, adaptive boosting (AdaBoost) and random forest classifiers achieved the highest classification accuracy of 96.75, 86.49 and 84.66% to predict three pinches, respectively. Conclusions. Predicting pinch strength and determining the predictive hand-forearm anthropometric and socio-demographic characteristics using ML may pave the way to designing an enhanced tool handle and reduce common musculoskeletal disorders of the hand.

Objectives. This study conducted a comparative analysis of two catastrophic pipeline accidents in China in order to identify some common mistakes and lessons learned to prevent similar accidents. Methods. The 24Model was used in this study, which provides a universal pathway for accident analysis from the individual level to the organizational level. Results. There were similarities between the two cases in the aspects of the occurrence, development, emergency and causation at different levels: both were caused by leaks of pipelines and evolved into multiple explosions during emergency response; both leaks were caused by the corrosion of pipelines in the confined space of a damp or salt-spray environment; both were classified as 'responsibility accidents', and unsafe acts, such as the failure to identify hidden hazards of pipelines that were the direct cause of accidents, reflected the shortcomings of individual safety habitual behaviour in terms of knowledge, awareness, habits and psychology; weaknesses in the organizational management mainly concerned hazard identification, pipeline maintenance, emergency disposal, etc.; and there is not a good safety climate within the organization. Conclusions. Organizations should develop a closed-loop management system and strengthen the construction of safety culture, and the government should supervise the implementation of procedures.

目的。规定测定 BLH 加权辐照度 LB,用于评估角度副边 α≥11mrad 的聚光灯。对于较小的光源,也可使用 BLH 加权辐照度 EB。在受委托进行风险评估(RA)的人员中,适当的仪器并不常见,尤其是枸杞辐照度的测量可能具有挑战性。因此,我们提出了一种实用的 BLH RA 方法,该方法基于照度、Ev、预先计算的发光辐射黑体 BLH 效应、KB、vPlanck 和固角考虑因素。方法。对该方法的实用性进行了研究,并与其他 RA 方法进行了比较。结果。为确保所应用仪器的可比性,在靠近辐射度标准的地方进行了测量,结果显示偏差在灯的扩展不确定度(4%)范围内,而距离较远时偏差为 ±15%。针对复杂的 LED 聚光灯,所有检测到的值都可以通过 RA 方法转换为枸杞光,误差在 ±20% 以内。在对多个聚光灯进行的两次实地测试中,通过不同的 RA 方法得出的最大允许照射时间在±30% 的不确定性范围内基本一致。结论对于工作场所白光源的 BLH RA,可以得出结论,建议的 Ev 方法总体上是实用的。

The present study aims to explore the mechanism for the impact of job embeddedness on safety performance, the mediating role of perceived insider status and the cross-level moderating role of safety climate among miners. The questionnaire data used for analysis in this study were collected from 310 miners in 38 coal mine production teams in China. Bootstrap analysis was performed to explore the mediating role of perceived insider status, and multilevel linear analysis was performed to explore the cross-level moderating role of safety climate. The results showed that job embeddedness was positively related to miners' safety performance; perceived insider status mediating the relationship between job embeddedness and miners' safety performance; and safety climate moderating the relationship between perceived insider status and miners' safety performance across levels.

Sixteen standing male participants were subjected to fore-and-aft sinusoidal vibration with peak magnitude and frequency in the range 0.44-4.431 ms-2 and 2-6 Hz, respectively. The fore-and-aft, lateral and vertical transmissibilities to the first dorsal vertebra (T1), eighth dorsal vertebra (T8), twelfth dorsal vertebra (T12), fourth lumbar vertebra (L4) and head were measured. Large inter-participant variability was observed in the transmissibilities at all locations. Nevertheless, peaks in the range 3-4.5 Hz were identified at all locations, implying a whole-body resonance in this frequency range. The response was found dominant in the mid-sagittal plane as the lateral transmissibility showed low values. Below 4.5 Hz, the fore-and-aft transmissibility increased with moving from caudal to cranial locations of the upper body. However, at higher frequencies, the opposite trend was observed. The results can be used for developing models that may help understand how vibration affects health and comfort.

Objectives. Upon immersion in water, a cascade of human physiological responses is evoked, which may result in drowning death. Although lifejackets are over 80% effective in preventing drowning, many people in lakeside fishing communities in Uganda shy away from wearing them because of active distrust in the quality of the lifejackets on the local market. No study has determined the veracity of these claims. This study determined the seaworthiness of lifejackets sold at landing sites of Lake Albert, Uganda. Methods. Using a within-person repeated assessment design, we tested 22 new lifejacket samples obtained from landing sites of Lake Albert, Uganda. We conducted water entry, righting, floatation stability and minimum buoyancy performance tests. Results. All the lifejacket samples failed the minimum buoyancy functional requirements test; the average buoyancy was 80 N (SD 13). Only 4% of the lifejackets passed the righting test within 5 s. For floatation stability, 45% of the lifejackets sank earlier than 48 h of placement in water and also failed water entry tests by getting dislodged from the wearer. Conclusion. The lifejackets sold at the landing sites of Lake Albert do not meet minimum seaworthiness functional requirements. The government should regulate the quality of lifejackets on the local market.

Objectives. The unique properties of nanomaterials have turned them into an emerging threat for humans and the environment. This study therefore aimed to review exposure control measures proposed for nanomaterial-involved activities. Methods. This study is based on the published guidelines of different organizations on safe handling of nanomaterials. The search for documents was provided using the keywords 'Exposure controls', 'Good practices', 'Working safely', 'Safe practices', 'Handling safely', 'Safety guide' and 'Safety and health', combined with 'Nanomaterials', 'Nanotechnology' and 'Nanoparticles' on different databases and websites. Results. Thirty-one guidelines from 27 organizations were included. Most of the guidelines recommended engineering controls, administrative controls and personal protective equipment (PPE). Changing the physical form of nanomaterials or the process, using prevention through design (PtD) and using green chemistry principals were other suggestions to reduce exposure to nanomaterials. Conclusions. Considering the difficulty of implementation and case specificity of the solutions of the first two priorities of the hierarchy of controls (elimination and substitution), the emphasis of the guidelines on the next three priorities for controlling exposure to nanomaterials is understood. The type and method of using PPE and engineering controls should be resolved by referring to cutting-edge articles.

Objectives. Although various studies have examined the relationship between ergonomic factors and employee well-being, the impacts of ergonomic factors on workers' capability for innovation have not yet been studied in the manufacturing industry. This study advances understanding of the relationship between ergonomic risk factors and employees' capability to innovate and to feel good at work in the manufacturing sector. Methods. The analysis uses the structural equation modeling technique based on cross-sectional data collected from 200 experienced workers in manufacturing industries using self-administered close-ended questionnaires. Results. Findings from this research show that the main ergonomic factors influencing the well-being and innovation capability of employees in the manufacturing industry are neutral awkward posture, psychological risk factors and effective utilization of information and communications technology infrastructures. Thus, ergonomic factors are significantly correlated to the innovation capability of employees. Conclusion. As there have been no studies addressing the integration of ergonomic risk factors and the capability for innovation of employees in the manufacturing industry, this study provides a unique contribution to the body of knowledge. Further research is also required to develop an in-depth understanding of the relationship among components of each ergonomic risk factor, and the well-being and innovation capability of employees.

Objectives. Improvement of the professionalization level for the new generation of construction workers (NGCWs) is critical to upgrade the construction industry. It also provides a new approach to reduce their unsafe behaviour. The purpose of this study is to analyse the correction mechanism of the professionalization level on NGCWs' unsafe behaviour. We examined the mediating role of work-family conflict and job burnout on impacting NGCWs' unsafe behaviour. The moderation effect of the NGCWs' perceived organizational support was also examined. Methods. The cross-sectional study was conducted based on structural equation modelling, confirmatory factor analysis and regression analysis with a sample of 496 NGCWs in China. Results. The professionalization level can effectively correct NGCWs' unsafe behaviour. Job burnout can independently mediate the relationship between professionalization level and unsafe behaviour and act as a serial mediator for work-family conflict. Moreover, the high level of perceived organizational support will effectively suppress the effect of work-family conflict on job burnout. Conclusions. Improving the professionalization level is an effective way to correct NGCWs' unsafe behaviour. Moreover, management should help the NGCWs balance work and family, to alleviate burnout. Additionally, it is suggested that management should ensure the NGCWs perceive the organizational support.
