阿拉山口口岸站货运安全问题的分析及对策

针对阿拉山口站货运作业中存在散堆装货物超载、成件小包装货物超载、集装箱偏载等问题,提出严格执行作业流程,约束和规范装载机械司机的操作行为,消除监控盲区,建立抽检制度、建立超偏载检测装置故障停用应急机制,建立装车前对货件标重检斤的制度,约束国外发货人的行为,保证货物装箱质量等保障货物运输安全的对策。     

基于知识积累的软件运行剖面生成方法及黑箱测试技术

软件的黑箱测试是一个面向用户的软件测试方法，当它以运行剖面为基础生成测试案例时，运行剖面的完备性将直接影响其测试结果的可信性，基于知识积累的软件运行剖面生成方法就是试图通过知识的获取和积累使生成的运行剖面日趋完备，从而达到黑箱测试技术在某些特殊的软件测试领域中更具实用和可信。文章讨论了软件 运行剖面的完备性和软件失效类等概念，提出了一种基于知识各界的软件运行剖面生成广阔圾黑箱测试技术，这种技术现已

The future of road safety: A worldwide perspective

Estimates by the World Health Organization suggest that, on a yearly basis, road crashes kill 1.25 million people—nearly 3400 road fatalities per day—and injure up to 50 million. Traffic injuries are not equally spread over the world, however; some countries are hit harder than others, and the chance of being killed in a road crash depends on where one lives. Almost 90% of all traffic casualties occur in low- and middle-income countries (LMIC). Globally, the number of fatalities per 100,000 population (mortality rate) ranges from less than 3 to almost 40. The rate is less than 9 in high-income countries (HIC) but averages around 20 in LMIC, with the African region demonstrating the highest rate (26.6). While road safety trends have been positive in HIC over the last few decades, trends in LMIC are not telling a positive story: road fatalities are expected to increase to almost 2 million road fatalities per year by 2020.The United Nations has adopted several resolutions on road safety and proposes actions to tackle the global road safety crisis. Considering the current level of road safety to be unacceptable, the UN has taken several initiatives. One effort, the Decade of Action for Road Safety 2011–2020, has generated substantial activity around the world over the last couple of years. Furthermore, it is very encouraging that the UN included road safety in the Sustainable Development Goals that it laid out in September 2015. Road safety is part of the public health agenda and the urban development agenda. Measured in “real actions,” however, the responses so far from the overall global community and individual countries do not suggest that we are already on the right track to bringing down the death toll on roads.The future of road safety is uncertain and definitely not the same for all regions of the world. Countries with a mature road safety approach and an ambition to make further progress are expected to move in the direction of a pro-active approach: a Safe System approach. It is reported that many LMIC, meanwhile, are on the brink of designing road safety strategies and implementing action plans. The international community is willing to support LMIC, but LMIC cannot simply copy successful HIC strategies because local circumstances differ. The principles of successful HIC strategies are applicable, but the priorities and action plans should take root in and align with local conditions.
