目的 为精准识别不同特点行业的工效学危险,基于快速上肢评价法(Rapid Upper Limb Assessment,RULA)评估框架,融合全身快速评价法(rapid entire body assessment,REBA)和工作姿势分析系统(ovako working posture analysing system,OWAS)开发《工效学综合评估量表》.方法 于2023年5月至2024年5月,基于比例推理法、分段函数法,对齐RULA和REBA的算法逻辑,推理出创新量表修正内容的评估规则,随机选取20个姿势进行相关性验证.结果 在α=0.01的显著性水平下,《工效学综合评估量表》的归一化评分与RULA的相关性系数r=0.845,与REBA的相关性系数r=0.633;《工效学综合评估量表》的行为等级评分与RULA相关性系数r=0.911,与REBA的相关性系数r=0.737,都存在明显相关性.结论《工效学综合评估量表》具有较高的可靠性,可用于不同工作场所和工作内容的作业活动,有助推进职业接触危险工效学评估的标准化.
Objective To accurately identify occupational health and safety hazards in different industries with distinct characteristics,a comprehensive occupational ergonomics assessment scale was developed by integrating the Rapid Upper Limb Assessment(RULA)evaluation framework,the Rapid Entire Body Assessment(REB A)and the Ovako Working Posture Analysing System(OWAS).Methods Between May 2023 and May 2024,based on the proportional reasoning method and segmented function method,the algorithm logic of RULA and REBA was aligned,and the evaluation rules for the revision content of the innovation scale were inferred using the method of proportion reasoning.Twenty postures were randomly selected for correlation verification.Results The results showed that at a significance level of α=0.01,the normalized score of the comprehensive ergonomic assessment scale had a correlation coefficient of r=0.845 with RULA and r=0.633 with REBA.The behavioral level score of the comprehensive ergonomic assessment scale had a correlation coefficient of r=0.911 with RULA and r=0.737 with REBA,indicating significant correlations.Conclusion The innovative comprehensive ergonomic assessment scale has high reliability and can be used for work activities in different workplaces and work contents,promoting the standardization of ergonomic assessment of occupational exposure hazards.
