Data were collected through the distribution of questionnaires and the recording of individual and job-related characteristics during the period 2006-2009. The questionnaires used were the Quick Disabilities of the Arm, Shoulder and Hand(QD) Outcome Measure, the Work Ability Index(WAI) and the ShortForm-36(SF-36) Health Survey. The QD was divided into three parameters-movement restrictions in everyday activities, work and sports/music activities-and the SF-36 into two items, physical and emotional. Multiple linear regression analysis was performed by means of the SPSS v.22 for Windows Statistical Package.RESULTS The answers given by the participants for the QD did not reveal great discomfort regarding the execution of manual tasks, with the majority of the participants scoring under 5%, meaning no disability. After conducting multiple linear regression, age revealed a positive association with the parameter of restrictions in everyday activities(b = 0.64, P = 0.000). Basic education showed a statistically significant association regarding restrictions during leisure activities, with b = 2.140(P = 0.029) for compulsory education graduates. WAI's final score displayed negative charging in the regression analysis of all three parameters, with b =-0.142(P = 0.0), b =-0.099(P = 0.055) and b =-0.376(P = 0.001) respectively, while the physical and emotional components of SF-36 associated with movement restrictions only in daily activities and work. The participants' specialty made no statistically significant associations with any of the three parameters of the QD.CONCLUSION Increased musculoskeletal disorders of the upper extremity are associated with older age, lower basic education and physical and mental/emotional health and reduced working ability.展开更多
噪声是煤矿井下主要危害,对人体视觉系统的影响不容忽视。为了提高暴露在噪声环境中工人的视觉认知能力,进而减少人因事故的发生,针对视觉认知随噪声暴露时间的变化进行研究,利用Eye Link II眼动仪采集被试者的平均注视时间、平均眼跳...噪声是煤矿井下主要危害,对人体视觉系统的影响不容忽视。为了提高暴露在噪声环境中工人的视觉认知能力,进而减少人因事故的发生,针对视觉认知随噪声暴露时间的变化进行研究,利用Eye Link II眼动仪采集被试者的平均注视时间、平均眼跳幅度和眼跳次数3个眼动指标来衡量视觉认知能力随着综采工作面噪声暴露时间的变化。结果表明:1)噪声能够使视觉注意力下降,对视觉认知效率的影响不显著,对视觉辨识能力的影响较复杂;2)噪声在0-10 min和40-55 min时间段对视觉注意力影响较严重,在0-15 min和50-80 min时间段对视觉辨识能力影响较严重;3)被试者随时间变化出现视觉性疲劳后,噪声可轻微提高视觉认知效率和视觉辨识能力。展开更多
