为准确预测量化我国职业病的发病趋势,在灰色GM(1,1)模型的基础上结合马尔科夫过程构建灰色GM(1,1)-马尔科夫预测模型,探讨灰色GM(1,1)-马尔科夫模型在职业病预测领域的应用。通过平均相对误差、后验差比值、小误差概率3个指标对该组合模型的预测精度进行评估。结果表明:10维灰色GM(1,1)-马尔科夫模型与原始数列的拟合程度较高,预测精度等级为一级(好),该组合模型的预测精度优于单一的灰色GM(1,1)预测模型;在遵循新陈代谢原理的情况下,我国职业病发病呈现上升态势,2015—2018年的职业病发病例数依次为31 196,36 284,37 724,39 147例。 相似文献

系统比较中国现行职业接触限值标准GBZ2.1-2007与德国职业接触限值MAK在定义、制定原则和具体数值方面的差异,为中国GBZ2.1的修订提供建议和依据。将 GBZ2.1中规定的OELs与德国MAK于2015年公布的化学有害因素 OELs ,按不同类型建立比较分析数据库,并进行比较分析,分析结果表明:中德2国在职业接触限值的制定原则,化学有害因素的来源、数量与标识等方面有显著差异。 因此,我国应加强对化学性有害因素孕期毒性接触限值的研究和应用。中德在选择化学性有害因素制定OELs时各有侧重,我国在重金属方面制定的OELs,如:钴、钼、铍、铊等,是德国MAK以及美国ACGIH中所未有的,而德国则不再为致癌物质制定OELs。中、德均制定有OELs的化学性有害因素在数值上差异较大,中国有部分OELs同时高于德国MAK和美国ACGIH。我国的职业接触限值更新频率较慢,应缩短OELs更新周期,在对现行的GBZ2.1进行制修订时,可将发达国家OELs作为1项参考。德国风险分级评估方法对致癌物质的管理和评估值得进一步探讨及研究。 相似文献

The implementation of a successful ergonomic and medical intervention program designed to reduce the number and severity of injuries and illnesses and the associated levels of discomfort in the workplace is presented. Because of the recent activity concerning the on-again-off-again Occupational Safety and Health Administration (OSHA) Ergonomic Program Standard questions have been raised as to the value and effectiveness of an organization’s ergonomics program. In light of these concerns, the immense cost associated with work-related injury and illness, and the related pain and suffering associated with such injuries and illnesses, it is important to present a workable and effective ergonomic and medical intervention program. The results of this applied study demonstrate that through the application of an ergonomic and medical intervention program, workplace-related injuries and illnesses can be reduced or eliminated. 相似文献

This review describes the general provisions of and the philosophy behind European Directive 2004/40/EC and ICNIRP (International Commission on Non-Ionizing Radiation Protection) guidelines. As an example of national legislation on the protection of workers against excessive electromagnetic field exposure, regulations established in Poland are summarized. The problems of a practical implementation of the Directive’s provisions are discussed. 相似文献

Case-study research was carried out with a view to find the attributes of occupational injury among workers in the chemical industry and to enhance safety issues. Injury data were collected and processed in terms of different variables, such as age, gender, skills, type of hazard, etc. Pareto analysis was then applied to find a pattern of occupational injury among the workers. The study revealed that 79.52% of the injured workers were in the 40–59 age group; 57.14% of accidents occurred during the 1st shift; 73.26% of accidents caused injury to hands, feet, chest to thigh, arms and eyes; and 70.93% of injuries were caused by pumps, carrying and lifting, vehicles, pipelines, valves, and grinding. Surprisingly, no one was injured in the group of temporary workers. The paper also provides specific suggestions followed by some action plans. 相似文献

A computerized handheld procedure is presented in this paper. It is intended as a database complementary tool, to enhance prospective risk analysis in the field of occupational health. The Pendragon forms software (version 3.2) has been used to implement acquisition procedures on Personal Digital Assistants (PDAs) and to transfer data to a computer in an MS-Access format. The data acquisition strategy proposed relies on the risk assessment method practiced at the Institute of Occupational Health Sciences (IST). It involves the use of a systematic hazard list and semi-quantitative risk assessment scales. A set of 7 modular forms has been developed to cover the basic need of field audits. Despite the minor drawbacks observed, the results obtained so far show that handhelds are adequate to support field risk assessment and follow-up activities. Further improvements must still be made in order to increase the tool effectiveness and field adequacy. 相似文献

Identification and determination of polycyclic aromatic hydrocarbons (PAHs) in Diesel exhaust in the working environment and assessment of workers’ occupational exposure to these suspected human carcinogens were the aim of this experimental investigation.The range of exposure factors calculated on the basis of 9 individual PAH concentrations determined in personal air samples shows that time-averaged concentration of these compounds did not exceed the Polish Maximum Admissible Concentration (MAC) value for PAHs, that is, 2 μg·m–3. The highest concentrations of PAHs were determined in the breathing zone of forklift operators. The maximum exposure factor was 0.427 μg·m–3 (about 1/4 of MAC). 相似文献

The article reflects on the changing world of work, and the challenges presented to both occupational health and occupational health education. We draw on the 63 preparatory workshops and the international conference in the “Work Life 2000: Quality in Work” program, an initiative of the Swedish Presidency of the European Union. The International Commission on Occupational Health is introduced, with particular concentration on a current practical project initiated by the Department of Health in South Africa, intended to lead to a set of projects, networking for occupational health education in developing countries. The practical initiatives cast light on a new set of issues that arise when occupational health and safety crosses cultural barriers, and previously separate comparative cases are linked. 相似文献

There is a relationship between the changes in work-related diseases and the following factors: the transformation of the organization of work, organizational development, as well as human and social changes in the work environment. These factors also influence the maintenance of industrial health and safety standards at work. Safety technology will continue to be important, but will be reduced in significance compared to the so-called soft factors, that is, all dimensions and parameters affecting people’s health and social environment at the work place.It seems that in the future the relationship between the social resource development and work protection will become more relevant. Social resource development influences the quality of work performance and motivation, the quality of work and work protection, the likelihood of accidents and breakdowns, and the level of self-control and capacity of change.The consequences of work protection research will be discussed in this article with a focus on the contribution of social sciences. 相似文献
