简介:摘要目的研究分析<3岁儿童营养不良的相关影响因素及干预措施。方法此次研究的对象是选择2014年3月~2016年4月从本市的幼儿园中随机选择10所幼儿园,对所有幼儿园<3岁的儿童进行调查研究。结果一共有2993名儿童入选,判定为营养不良的儿童一共有237名,占入选总人数的7.9%。经单因素分析,男童、贫血、私立幼儿园儿童的营养不良比例较大,年龄越大,营养不良比例越小,患有龋齿的儿童营养不良比例较小。经多因素分析,私立幼儿园为儿童营养不良危险因素,保护因素有年龄大、女童、牙齿数。结论本市低龄儿童和私立幼儿园儿童的营养不良比例较大,给予针对性的干预,可以有效控制<3岁儿童营养不良的发生率。
简介:摘要VoLTE作为LTE网络终极语音解决的演进方案,实现了在LTE覆盖区内语音和数据都承载在LTE网络。但是在商用的初期,全国大多数省市的VoLTE优化仍处于摸索阶段。如何对VoLTE进行优化,提升客户体验,将是一个长期课题。本文将对无线的优化手段进行探讨,为后期VoLTE优化提供参考与建议。截止2015年11月,中国移动的LTE基站已达107万个,两年时间内建成了世界上最大的LTE网络。但是在初期,LTE网络只承载数据业务,语音业务仍是采用2G/3G网络承载的方案。随着网络标准演进和技术逐步成熟,VoLTE是未来主流的语音解决方案。为了解决这个问题,从用户使用感知的角度出发,探讨如何在弱覆盖场景下提升VoLTE通话质量,并针对广域场景及城区小区边缘分别提出了优化解决方案。
简介:In France we have this tradition of workerism which is anti-intellectual. The unions are very hostile to intellectuals and the intellectuals are very distant from workers. In 1968 it was very visible. Now for the first time because of the failure of Soviet Marxism we are free from that. So I can speak with a CGT official as I am speaking to you. They are very open. In a sense intellectuals like me did not exist 20 years ago. People like Sartre and Foucault were sympathetic to the movement,There are powerful political obstacles between people. The main obstacles come from the social democratic movement. If we succeed in overcoming these it will lead to a genuine Third Way which will be much more radical. We need to build the left of the left. In the ecology movement you have people who are really on the left--even among the Communist Party,Whether the revival of the left will lead to a new party is an open question. So too is how ideas will be clarified. The main thing is to build the movement. No one should doubt the radical changes that are happening in the way people think. I am more optimistic about the future than at any time in the last three decades
