ERGONOMICS ASSESSMENT METHOD FOR WORK/WORKER SYSTEMS

通常，人体工学研究的目标是一个或多个 以下：在危害和健康之间建立(因果)联系 结果；描述危险和危险之间的剂量反应关系 健康后果；确定危害的暴露阈值；或 展示干预措施的有效性。坚持不懈的努力 这些目标，在继续试图了解糖尿病的病因中 肌肉骨骼损伤。然而，与工作相关的病因学 肌肉骨骼疾病(WRMSD)仍不清楚。事实上，这项工作- 肌肉骨骼疾病的相关性仍然是一个有争议的问题。 最近，关于其病因的多因素理论已经被 建议。然而，很少有人体工程学研究能充分解决 人体工程学的多个方面：生物力学、心理社会因素、工作 组织和个人属性。有些方面要么被忽略 或者评估很差。这可能会导致关于 其影响的强度，以及基准设计的有效性 可以根据研究结果提出的标准。 该项目的具体目标是开发和应用一种 工作人员特征的综合评估方法 系统从人体工程学的角度来看。方法论将包括 几个标准化工具(调查问卷、工作测量方案、 和生物力学评估)。调查问卷提供了定性的 关于工人、工作和工作场所的信息(人口统计数据和 心理社会观点、工作组织和工作设计)。工作 测量协议提供定量的时间信息和 定性的生物力学数据。生物力学评估提供了一个 开展观察到的活动所需的内部活动的观点 在工作场所。评估的产品将是多维的 工作和员工配置文件。工作人员配置文件将描述 员工与其工作的互动(个人属性、 心理社会视角、人口统计学、工作历史和健康状况 历史和现状)。工作概况将表现为体力和 行政工作要素。这些配置文件将一起用于 确定员工属性和感知之间的关联，员工 健康结果(肌肉骨骼损伤和其他劳损)和工作 配置文件。该方法将应用于移动计算，并 办公室人体工程学的新兴领域。这样做的长期目标是 研究方向是开发与工作相关的预测模型 肌肉骨骼损伤，包括身体、心理社会、工作 组织和个人因素，具有普遍适用性 在研究中使用的作业类型从最初的探索到 干预示范努力。

Typically the goals of ergonomic research are one or more of the following: establish a (causal) link between hazards and health outcomes; characterize dose-response relationships between hazards and health outcomes; identify exposure thresholds for hazards; or demonstrate efficacy of interventions. Efforts persist towards all these goals, in continued attempts to understand the etiology of musculoskeletal injuries. Yet, the etiology of work-related musculoskeletal disorders (WRMSDs) remains unclear. In fact, the work- related-ness of musculoskeletal disorders remains a contentious issue. More recently, multifactorial theories for their etiology have been proposed. Yet few ergonomics research studies adequately address the multiple facets of ergonomics: biomechanics, psychosocial factors, work organization, and personal attributes. Some facets are either ignored or poorly assessed. This may lead to incorrect conclusions about the strengths of their effects, and the validity of benchmark design criteria that may be proposed based on a study's results. Specific aims of the project are development and application of a comprehensive assessment methodology for characterizing the work-worker system from an ergonomics perspective. The methodology will consist of several standardized tools (questionnaire, work measurement protocols, and biomechanical assessment). The questionnaire provides qualitative information on the worker, work, and workplace (demographics and psychosocial perspectives, work organization and job design). Work measurement protocols supply quantitative temporal information and qualitative biomechanical data. Biomechanical assessment provides a view of the internal activity necessary to carry out activities observed in the workplace. Products of the assessments will be multi-dimensional work and worker profiles. The worker profile will characterize the worker's interaction with his or her work (personal attributes, psychosocial perspectives, demographics, work history, and health history and status). The work profile will characterize physical and administrative work elements. Together the profiles will be used to identify associations between worker attributes and perceptions, worker health outcomes (musculoskeletal impairment and other strains), and work profiles. The methodology will be applied to mobile computing, an emerging area of office ergonomics. The long term objective of this line of research is development of a predictive model of work-related musculoskeletal impairment, that includes physical, psychosocial, work organization and personal factors, and has generalized applicability across job types for use in research from initial exploration to intervention demonstration efforts.
