工作场所职业工效相关因素及其管理初探

为了探讨工作场所职业工效管理的基本策略和方法,在概述职业工效相关因素类别、相互关联及评价方法等基础上,提出基于职业病危害防治要求、风险管理理念和管理体系建设模式的职业工效不良因素干预管理的初步策略及实施要点。研究结果表明:工作场所职业工效相关因素包括个体特征、工艺设备及其布局、工作系统设计、作业环境、作业管理和社会心理因素等,不同因素间存在直接或间接的相互影响,并最终影响到微观层面劳动者职业活动的工效特点及宏观层面工作场所整体的职业工效特征;实施有效的职业工效管理,在于科学辨识、评估不良职业工效因素的基础上,进一步在职业病危害预防控制的不同阶段采取合理可行的管理方法进行干预,并持续改进。     

人-机系统事故预防理论研究

分析人-机系统事故发生原因,剖析经典以人失误为主因的事故致因模型存在的不足,在该模型基础上增加"刺激"形成的原因,构建了改进事故致因模型。对两模型进行比较研究,指出人机工程学与防止事故的关系,提出了人机工程学防止事故的方法,并给出人机界面合理性主观评价检查表。研究及论证表明:预防人-机系统事故的本质在于有效防止人失误的发生,除安全管理措施以外,最重要的是人机工程学问题,笔者提出的基于人机工程学的人-机系统事故预防理论,对人-机系统事故的预防起到积极的指导作用。

工程项目现场安全标志有效性评价

为改善工程项目现场作业安全状况,需要对安全标志的有效性进行评价。通过划分施工人员的认知行为阶段,从人机工程学系统优化的角度构建安全标志有效性评价指标体系,确立指标打分规则,采用网络层次分析法(ANP),运用超级决策(SD)软件确定指标权重、综合评分,并加以示例说明。结果表明:安全标志的有效性受注意阶段的显著性、识别阶段的可理解性、判断阶段的安全倾向性和行为阶段的易遵守性交互影响,其中,安全倾向性权重值最高。     

Expert system application for prioritizing preventive actions for shift work: shift expert

Introduction. Shift patterns, work hours, work arrangements and worker motivations have increasingly become key factors for job performance. The main objective of this article is to design an expert system that identifies the negative effects of shift work and prioritizes mitigation efforts according to their importance in preventing these negative effects. The proposed expert system will be referred to as the shift expert. Methods. A thorough literature review is conducted to determine the effects of shift work on workers. Our work indicates that shift work is linked to demographic variables, sleepiness and fatigue, health and well-being, and social and domestic conditions. These parameters constitute the sections of a questionnaire designed to focus on 26 important issues related to shift work. The shift expert is then constructed to provide prevention advice at the individual and organizational levels, and it prioritizes this advice using a fuzzy analytic hierarchy process model, which considers comparison matrices provided by users during the prioritization process. An empirical study of 61 workers working on three rotating shifts is performed. After administering the questionnaires, the collected data are analyzed statistically, and then the shift expert produces individual and organizational recommendations for these workers.     

Representativity and univocity of traffic signs and their effect on trajectory movement in a driving simulation task: Warning signs

Objective: The effect of traffic signs on the behavior of drivers is not completely understood. Knowing about how humans process the meaning of signs (not just by learning but instinctively) will improve reaction time and decision making when traveling. The economic, social, and psychological consequences of car accidents are well known.

Methods: This study sounds out which traffic signs are more ergonomic for participants, from a cognitive point of view, and determines, at the same time, their effect in participants' movement trajectories in a driving simulation task.

Results: Results point out that the signs least representative of their meaning produce a greater deviation from the center of the road than the most representative ones.

Conclusions: This study encourages both an in-depth analysis of the effect on movement of roadside signs and the study of how this effect can be modified by the context in which these signs are presented (with the aim to move the research closer to and analyze the data in real contexts). The goal is to achieve clarity of meaning and lack of counterproductive effects on the trajectory of representative signs (those that provoke fewer mistakes in the decision task).
