RAMP I is a screening tool developed to support practitioners in screening for work-related musculoskeletal disorder risk factors related to manual handling. RAMP I, which is part of the RAMP tool, is based on research-based studies combined with expert group judgments. More than 80 practitioners participated in the development of RAMP I. The tool consists of dichotomous assessment items grouped into seven categories. Acceptable reliability was found for a majority of the assessment items for 15 practitioners who were given 1?h of training. The usability evaluation points to RAMP I being usable for screening for musculoskeletal disorder risk factors, i.e., usable for assessing risks, being usable as a decision base, having clear results and that the time needed for an assessment is acceptable. It is concluded that RAMP I is a usable tool for practitioners. 相似文献

More than 20000 handling manoeuvres in loading or unloading trailers in a large transportation company were observed. The aim of the study was to determine the frequency and nature of the incidents occurring whilst handling. The incidents were recorded and interpreted from a double perspective, namely as risk factors and as activity regulation factors. The study showed that on average, one incident occurred in every seven handling manoeuvres: 71% of them were related to the environment, and 29% to the activity. While numerous, the environment-related incidents were generally without consequences. In this respect, the activity incidents appeared more risky; also, the majority of these incidents occurred during the load positioning phase. The study also showed that loads are re-handled twice as often in unloading as in loading, the frequency of re-handlings varying widely from one handler to another. The reasons why so few of the observed incidents are reported in accident studies and their significance in the understanding of handling problems are discussed. 相似文献

This paper examines the impact of training programs on the ability of trainee watch officers to make decisions in collision avoidance situations.It draws on previous studies which have shown that experts are able to manage complex situations in an acceptable way. However, observations of students on simulators have revealed that many of them are unable to manage such situations or even to recall their main features. It is therefore necessary to identify new training tools that will give trainees the capacity to assess a situation quickly and accurately, and to perform satisfactory actions. These would be in addition to formal regulations.Exercises were designed to evaluate the impact of such tools on the decision-making process of trainees. The impact of the type of navigation experienced by trainees during their on-the-job training was also evaluated.Results showed that decision-making exercises did tend to improve the trainees’ capacity to analyse a complex situation; however, they did not have a clear impact on the manoeuvre performed. On the contrary, there was an obvious difference between the trainees who experienced complex avoidance situations during their on-the-job training period and those who did not.At a time where ship-owners are looking to reduce the length of the “on-the-job” training period, these results point to its vital importance. 相似文献

抗生素菌渣的环境无害化利用处置目前已成为行业和政府管理部门亟待解决的难题.为有效实现抗生素菌渣的资源化利用,开展了经SEA-CBS高效复合资源化利用技术制成的吉他霉素和螺旋霉素菌渣有机肥理化特性研究,并分析了未施肥、施加不同比例的商品肥和菌渣有机肥对苦苣生长的影响.结果表明:吉他霉素和螺旋霉素菌渣有机肥的pH分别为6.59和7.92,含水率分别为5.21%和10.60%,抗生素残留均未检出;吉他霉素菌渣有机肥中w(Cr)、w(Pb)和w(As)相对较高,分别为33.40、7.05和1.57 mg/kg,而w(Cd)(0.34 mg/kg)和w(Hg)(低于0.002 mg/kg)相对较低;两种抗生素菌渣有机肥的总养分含量均在5%以上,w(有机质)均大于80%,均符合NY 884—2012《生物有机肥》及NY 525—2012《有机肥料》中的相关限值.植株生长试验研究发现,施加1%和3%的吉他霉素菌渣有机肥时,苦苣的株高、鲜质量和干质量均优于未施肥处理,且株高均大于施入商品肥处理;施加1%螺旋霉素菌渣有机肥下苦苣生长性能优于未施肥情况.研究显示,SEA-CBS技术可有效去除菌渣中残留的抗生素,并实现抗生素菌渣的资源化利用. 相似文献
