Hand anthropometric study in northern Colombia

The main purpose of this study is to gather information about the dimensions of the northern Colombian (Caribbean region) population, focusing on the dimensions of the hand and comparing them with measurements from other regions. Thirty-two hand dimensions were chosen and 120 males and 86 females were measured. Results indicated that there were differences between the dimensions of the hand for men and women, showing that men are larger. Also, there was a comparison made between some measurements of other studies in different regions of Colombia, the USA, Chile, Jordan, Korea and Japan. The results indicated important physiological differences between regions in Colombia and across countries. It was therefore concluded that differences in anthropometric measurements must be included in the design and procurement of machinery and apparatus in order to avoid productivity loss, occupational injuries or illness.     

Safety of stationary grinding machines – impact resistance of work zone enclosures

Guards on machine tools are intended to protect persons from being injured by parts ejected with high kinetic energy from the work zone of the machine. Stationary grinding machines are a typical example. Generally such machines are provided with abrasive product guards closely enveloping the grinding wheel. However, many machining tasks do not allow the use of abrasive product guards. In such cases, the work zone enclosure has to be dimensioned so that, in case of failure, grinding wheel fragments remain inside the machine’s working zone. To obtain data for the dimensioning of work zone enclosures on stationary grinding machines, which must be operated without an abrasive product guard, burst tests were conducted with vitrified grinding wheels. The studies show that, contrary to widely held opinion, narrower grinding wheels can be more critical concerning the impact resistance than wider wheels although their fragment energy is smaller.     

Are there any job resources capable of moderating the effect of physical demands on work ability? A study among kindergarten teachers

Background. It is recognized that teaching in a preschool context is physically demanding. Despite this, the consequences of physical demands on psychophysical health (including work ability) are significantly understudied among kindergarten teachers. Objectives. The aim of the present study is to examine (a) the association between physical demands and work ability and (b) whether psychosocial job resources buffer the negative impact of physical demands among kindergarten teachers. Method. A total of 426 kindergarten teachers employed in the municipal educational services of a city in northwest Italy filled out a self-reported questionnaire. Results. High association was found between physical demand and work ability. Moderated hierarchical regressions showed that decision authority, skill discretion, reward and meaning of work buffer the hampering effect of physical demands and work ability. No buffering effects were observed for support from superiors and colleagues. Conclusion. The present study has relevant, practical implications, highlighting the importance of investing in interventions encompassing a holistic perspective (e.g., psychosocial and ergonomic) in order to effectively combat the hampering effect of physical demands on work ability.

工作满意度对建筑工人不安全行为的矫正机制研究*

为探讨工作满意度对建筑工人不安全行为矫正机制,基于文献调研构建工作满意度对建筑工人不安全行为矫正机制理论模型,并通过验证性因子分析和结构方程模型分析,对理论模型进行实证检验。结果表明:工作满意度对建筑工人安全不服从行为和安全不参与行为有显著矫正作用,敬业度在工作满意度和建筑工人安全不服从行为与安全不参与行为间起完全中介作用。对于新生代建筑工人,工作满意度通过敬业度对安全不服从行为矫正效应小于对安全不参与行为的矫正效应,对于老一代建筑工人,矫正效应则相反。研究结果可为广大建筑施工企业矫正其工人的不安全行为提供依据。     

基于蝴蝶型突变理论的安全生产保障系统分析和探讨

利用突变理论探讨事故致因模型,揭示事故致因的基本要素及其内在联系,对构成的要素进行抽象化,将对众多复杂企业的不安全因素进一步归纳为"人-机-环境-管理"安全生产保障系统,分析建立该系统的必要性,在突变理论的蝴蝶型与该系统结合性的基础上,探讨和建立安全决策和安全对策模型,将企业的安全生产危险程度分为理想的安全区域、危险区域、相对的安全区域。提出了危险程度和安全状况改进的数学模型,蝴蝶型突变理论能够揭示企业的安全状况。     

安全伦理与安全生产——解析安全伦理命题,制定“道德的”安全生产激励政策

从分析社会发展对安全伦理命题的关注和中国安全生产问题所引发的道德问题入手,指明安全伦理命题对社会经济政治发展的正面作用;依据道德选择和道德评价时所诉诸的安全伦理原则,区分"道德的"和"不道德的"两种安全生产伦理范式,并在该基础上提出一个制定"道德的"安全生产激励政策的选择方案:建立国家工业事故预防的伦理战略和伦理指导制度;制定"公平的"、"合理的"安全资源分配政策;制定中小企业的"道德的"安全生产管理战略;建立安全活动领域的防腐败机制,维护社会正义;从"人权"道德规范出发,创立新的安全生产规范。

Driving factors and the implications of work choices of rural laborers in ecologically vulnerable areas in North China

Using rural survey data for the year 2009,we provide evidence of work choices of rural laborers in ecologically vulnerable areas in North China,and model these choices as a function of characteristics of individuals,households,and land endowments.The findings reveal large differences between males and females,and between non-farm employment and part-time farming engagement Land scarcity is still an important driving factor in non-farming participation of rural laborers in the study area;and in the current case of land productivity and the total amount of land,there are still surplus rural labor forces in the study area.Diversification of livelihood reduces the pressure on land,thus facilitating ecosystem conservation.So,the paper concludes with the argument that establishing coordination mechanisms among non-farm employment of rural laborers,agricultural production,and restoration of ecosystems are essential for mitigating the conflicts of ecological security,agricultural production,and rural development in mis area.
