Proposal for an integrative methodology to development the ergonomic program

This paper collects the experience for both, academic and professional practice, and deal with the stages and level of involvement from different elements in the organization. The work is focused in some kind of concentric cycles, the very outside circle is formed by those that interact with ergonomic process in a year period, and the inner cycles are those that acts in a daily or weekly intervention. The success of the program still depending on the good will of the managers, but any action directed on benefit of the people at work, enable the moral as well as indicators for health and safety.     

Maximum force levels in different positions of shoulder and elbow

The number of occupational diseases in Mexico is alarming and clearly it is important to do studies with the purpose of improving the design of workstations. The objective of this research is to determine the maximum force levels in different positions of shoulder and elbow. An experiment was conducted with 16 subjects between 18 and 28 years old: 8 male and 8 female. We considered 16 different positions, working with the right and left arm to perform the tasks of pull and push. The tasks consisted of pushing or pulling a dynamometer for a period of 3 seconds as hard as possible. The results were presented in tables. The tables show the mean, standard deviation and range of force levels in different positions.     

Burnout syndrome, working conditions, and health: a reality among public high school teachers in Brazil

The objective of the study was to evaluate the occurrence of Burnout Syndrome in 100 teachers of six public high schools and its correlation with working conditions in a southeast city of Brazil. Characterization of the sample occurred after application of a socio-demographic questionnaire. Evaluation of the working conditions was done by means of an Ergonomic Working Analysis. The presence of Burnout Syndrome was evaluated by means of the Maslach Burnout Inventory. The sample presented the predominance of women, with an average age of 40.4 and the majority married with children. Roughly 50% had less than 10 years of service, and more than half of the teachers taught more than 18 classes per week. Hoarseness after work was principally reported among women, which required many days off for health treatment. Environmental conditions reflect inadequacy in relation to noise, light, humidity and temperature. Presence of pain in the upper limbs was especially high among women. Risk of musculoskeletal disorders in the upper limbs predominated as moderately important to significant. We also identified an average distance walked by teachers of 1.5 Km and an average of 4.2 Kg of school supplies carried between classes. The Burnout Syndrome presented a high score for depersonalization principally among men, but it has association with both sexes. Emotional exhaustion correlates with noise, depersonalization, and personal fulfillment, in addition to the high number of weekly lessons. It can be concluded that Burnout syndrome is present among teachers, principally in terms of depersonalization, deserving the attention of government officials and the schools, as well as the teachers themselves.     

The contribution of ergonomics to risk analysis in the design process: the case of a future control room

The aim of this paper is to highlight how ergonomics contributes to risk analysis and risk management in a design project for a new reactor, the French EPR (European Pressurized Reactor). An iterative ergonomics design process has been conducted over the last 10 years through a Human Factors Engineering program at the French energy company EDF. A parallel has been drawn between a risk management process and this ergonomics process based on International Organization for Standardization (ISO) publications such as ISO/IEC Guide 73, ISO Guide 51, etc. The contribution of ergonomics to risk analysis is illustrated by an example: the automatic diagnosis, which is a very important technical device for safety. Five main types of risk have been identified via ergonomic analyses during the different design stages. Counter-measures have been implemented and their efficacy tested within the scope of new campaigns to assess human factors. However, the management of risks in such a design project requires the participation both of the different design entities involved in the project and of other experts in aspects of risk management, such as human reliability. The organization of collaborative participation remains a challenge to be addressed.

昌都地区区域经济发展战略研究

昌都解放以来,特别是实行民主改革以来,历届昌都地委领导团结带领昌都各族人民艰苦奋斗、艰难创业,取得了经济和社会发展的巨大成就,区域经济有了明显改善。但由于历史和现实的客观原因,昌都的区域经济发展仍然相对滞后,需要对区域经济发战略进行重新思考和定位。文章运用区域经济发展战略理论,提出了昌都今后一个时期的发展战略、发展重点及保障措施,旨在解决当前及今后一个时期昌都经济社会发展中的一些突出问题,促进昌都经济的跨越式发展和社会的长治久安。     

Individual and Contextual Correlates of Economic Difficulties in Old Age in Europe

With data drawn from the second public release version of the “Survey of Health, Aging and Retirement in Europe” (SHARE), we scrutinize individual and contextual (regional) correlates of economic difficulties among older Europeans, aged 65 or more. A logistic multi-level regression model with random intercept shows that the risk of being relatively poor varies considerably among the aged. We verified that the factors affecting poverty in each area are not merely the weighted sum of the effect of the more disadvantaged people within the same area, which also exists: poverty appears also significantly influenced by the specific context of residence.     

人口发展功能分区与主体功能分区的比较研究

以人口发展功能分区和主体功能分区的内涵特征为逻辑研究起点,采用规范研究与归纳总结相结合的研究方法,从功能区划的角度对两者的总体关系进行了比较分析。对比结果显示,两种区划都是我国体现人与自然关系的一种空间管制手段,但在功能、性质、作用和管理等方面存在的差异。在此基础上,通过找出两种功能区划统筹协调中存在的问题,简要地提出了协调两者的几点建议。     

西部农村留守妇女家庭压力及其影响因素分析

本文采用西部地区24个行政村千余名农村妇女的调查数据,探讨了农村留守妇女的家庭压力及影响因素。研究发现,留守确实增强了农村妇女的家庭压力,留守妇女承受的精神压力、经济压力、抚养赡养压力都要大于非留守妇女;留守妇女的年龄、家庭特征、当初择偶时对般配的重视程度、夫妻异质性、与外出丈夫的沟通状况、社会支持等因素对其家庭压力有不同程度的影响。提出建立夫妻间良好的沟通机制和构建社会支持网络的建议。     

人口红利、产业承接与农村劳动力就近转移——以成都城乡统筹试验区为背景

随着西部经济发展及中部地区的崛起。东部地区产业向中西部转移,中西部地区参与人口红利再分配成为必然。鉴于此。有必要及时调整农村就业政策,将农村劳动力就近转移作为一项主要的就业政策,以促进产业转移的顺利进行和人口红利的高效再分配。
