湘鄂赣农业资源与专业化区域化方向

湘鄂赣地理位置优越,农业资源丰富,稻谷、茶叶、麻类、棉花、油料、柑桔和淡水产品、禽蛋、肉类等在我国居有重要的地位,因此,大力发展三省农业生产,对我国人民实现小康生活具有战略意义。今后,要加速专业化区域化进程。我们找出生产潜力所在:改造低产田、低产园、低产水面;开发“三高”技术;开垦荒地、荒山、荒水;适当提高复种指数。通过建设,三省主要农产品将自给有余,还可满足国内外市场的需要。努力方向:高效农业开发——综合农业开发,吨粮田开发,玉米带开发,饲料稻开发,山区开发;合理布局农业生产;深化农业商品基地建设,发展综合利用,搞活商品流通;全面提高农业现代化水平,加强农业社会服务体系。     

爆炸冲击荷载对动物杀伤作用距离的试验研究

采用3 kg、5 kg和10 kg装药在自由场中爆炸,观察分析距炸点不同距离的家兔在爆炸冲击波下的伤亡情况.试验同时使用冲击波超压测量仪记录不同位置的冲击波超压.试验结果表明,在超压小于0.08×105 Pa时家兔基本安全,3 kg、5 kg、10 kg炸药爆炸时的安全距离分别为20 m、25 m、30 m.     

工伤保险行业差别费率确定方法探讨

制定合理的行业差别费率对于工伤保险基金的稳定、促进企业改善安全生产状况具有积极作用.我国工伤保险制度处于起步阶段,有些地区对行业差别费率厘定进行了探索,但费率与风险的关联性不强,影响了低风险企业参加工伤保险统筹的积极性.本文针对工伤统计数据缺乏的现状,分析了现阶段工伤保险行业差别费率确定方法的研究现状,重点讨论了确定行业风险等级的3种方法,即聚类分析法、风险系数测评和模糊风险评估法的应用过程以及优缺点;另外,强调了在确定行业风险指数时,应注意根据不同事故类别的严重度来确定各风险因素指标的权重大小.最后,应用风险评估理论分析工伤保险行业差别费率的运作机理,提出应用工伤赔付支出费用计算行业差别费率的数学公式,此公式原理清晰、操作方便,且有利于各统筹地区根据实际情况划分行业差别费率.     

日光温室黄瓜低温冷害风险评估技术研究

基于人工气候箱和大田试验观测结果,探讨了日光温室黄瓜生产低温冷害气象指标确定技术,将冬季黄瓜生产低温冷害分为无灾、轻灾、中灾和重灾4个等级,利用层次分析法和GIS技术,对日光温室黄瓜生产低温冷害综合风险进行评估.结果表明,山东省各级冷害出现日数随着低温冷害程度的加重呈减少的趋势,但区域间存在一定差异.鲁北、鲁西北北部、鲁中北部以及半岛内陆地区遭受低温冷害风险较高,半岛东部沿海、鲁西南、鲁南及鲁东南沿海区域风险较低,其他地区属于中度风险.     

Ergonomic Program Effectiveness: Ergonomic and Medical Intervention

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.     

Attributes of Occupational Injury Among Workers in the Chemical Industry and Safety Issues

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.     

The impact of implementation of the requirements of Standard No. OHSAS 18001:2007 to reduce the number of injuries at work and financial costs in the Republic of Croatia

This article contains the results of research into the impact of implementation of the requirements mentioned in Standard No. OHSAS 18001:2007 to reduce the number of injuries at work and the financial costs incurred in this way. The study was conducted on a determined sample by a written questionnaire survey method in the Republic of Croatia. The objective of the empirical research is to determine the impact of implementation of the requirements of Standard No. OHSAS 18001:2007 to reduce the number of injuries at work and financial costs in Croatia in business organizations that implement these requirements. To provide a broader picture, the research included the collection and analysis of data on the impact of the Standard No. OHSAS 18001:2007 on accidents and fatalities at work. Research findings are based on the analysis of performed statistical data where correlation and regression analysis has been applied.     

Review: The Dynamics of Near Vertex Head Impact and its Role in Injury Prevention and the Complex Clinical Presentation of Basicranial and Cervical Spine Injury

The clinical presentation of cervical and basilar skull fractures following bead impact is often complex, particularly when multiple noncontiguous fractures are present. Based on the results of 22 human cadaver head-neck impact experiments, a biomechanical framework of spinal injury is developed in which these complex cases may be better understood. This includes the significance of head rebound, head and neck decoupling, cervical spine buckling, cervical injury mechanisms, basilar skull fractures, and cervical spine tolerance. These data also demonstrate that compliant pads significantly increase the risk for spinal injury though they also significantly reduce peak head force and the head injury criteria (p < 0.04). On the basis of these observations, we hypothesize that impact injury should be modeled as the dynamic response of two large masses, coupled by a segmented curved beam-column composed of seven small masses with interposed nonlinear viscoelastic flexibility elements.
