摘要

手工丝网印刷(HSP)是占主导地位的纺织加工行业之一,在发展中国家农村地区及其周边地区的就业中起着重要作用。此外,大多数HSP行业都是小规模行业,工人是文盲或缺乏工作安全知识,管理层和工人在日常生活中都忽视了人体工程学问题。虽然各个研究小组都试图定性和定量地评估高温工场工人面临的工效学问题,但由于缺乏改善高温工场工人工效环境的直接解决方案,仍有巨大的空间可供进一步干预。本研究旨在重新设计HSP工人的刮刀架,并验证其对工人健康的影响。在本研究中,考虑到评估的人机工程学问题,对传统的橡胶刮刀进行了改进。为了评估设计干预,10名男性志愿者参与了研究,并使用传统的刮刀(干预前)和改进的刮刀(干预后)进行了HSP手术。进一步将研究人群分为对照组和腰痛组两组。收集表面肌电图(sEMG)信号、快速全身评估(REBA)评分和Borg量表数据,评估干预后的尝试程度。结果表明,改进的刮刀干预使REBA评分(姿势风险)降低了52%,博格量表(工人疼痛强度)降低了51%。此外,肌电图研究支持这些发现,显示腰痛组肌肉疲劳有所下降。本研究的结论是,改进的刮刀干预方面可以有效地改善HSP工人的人体工学姿势,减少肌肉骨骼疾病,并显着提高纺织工业的生产力。

Management of Hand Screen Printing Workers Health Using Ergonomic Design Intervention
Hand Screen Printing (HSP) is one of the dominant textile-processing industries that plays a significant role in the employment of people in and around the rural regions of the developing countries. Further, most of the HSP industries are small scale industries sector, workers are illiterate or lack work safety knowledge, also both management and workers ignore the ergonomic issues in their day to day life. Though various research groups have attempted to evaluate both qualitatively and quantitative the ergonomic issues faced by HSP workers, due to lack of direct solution to improve the HSP workers’ ergonomic environment, there is still a huge space is available for further intervention. The present study aims to redesign the squeegee frame for HSP workers and validate its effect over the workers’ health. In this study, the traditional squeegee was modified by considering the evaluated ergonomic issues. To evaluate the design intervention, ten male volunteers participated in the study and performed the HSP operation using both traditional squeegee (pre-intervention) and retrofitted squeegee (post-intervention). Further, the study population was divided into two equal group such as control group and low back pain (LBP) group. The surface Electromyogram (sEMG) signal, Rapid Entire Body Assessment (REBA) score and Borg’s scale data were collected, to assess the post intervention attempt. Result inferred that retrofitted squeegee intervention had reduced the REBA score (postural risk) by 52% and Borg’s scale by 51% (workers’ pain intensity). In addendum, sEMG study supported these findings by showing a decline in muscle fatigue for the LBP group. This study concludes that, retrofitted squeegee intervention aspect can be an effective agent to improve the ergonomic posture and reduce the musculoskeletal disorders among HSP workers and significantly increase the productive of textile industry.
