    2000年以来我国人口老龄化形势日益严峻,养老问题已经成为政府和学术界共同关心的、最迫切需要解决的焦点问题。相较于城镇,我国农村居民的养老问题则更为严峻。为了解决我国农村居民的养老问题,早在1980年代,我国就开始在一些经济发达、满足条件的地区探索性地构建农村社会养老保险体系。在前期农村社会养老保险制度的理论研究和试点经验的基础上,国务院于2009年9月明确提出开展新型农村社会养老保险试点,并充分阐述了新型农村社会养老保险制度的内容,决定于2009年实行新型农村社会养老保险制度,开展新型农村社会养老保险试点,此后逐渐增加试点县(市、区、旗)数量,最终实现在全国范围内实施。然而新型农村社会养老保...Since 2000,with the deterioration of China aging population problem, the government and scholars pay enormously attention to the supporting problem. Compared to cities, the rural supporting problems is more severe. In order to solving the rural’s aging population problem, in 1980s government has built rural social pension insurance in some developed rural areas.

    海水溶解无机碳(DissolvedInorganicCarbon,DIC)是表征海水碳酸盐体系的四大参数之一,也是海洋碳循环和海洋酸化研究的基础数据。目前,海水DIC数据的获取主要依靠科考船采集离散的样品进行分析,由此得到的数据时空分辨率低,无法满足当前海洋科学研究的需求。采用原位仪器进行长时间系列观测是获取高时间分辨率海水DIC数据的最佳手段。目前仍鲜有DIC原位测定仪的报道。本论文研制了原位DIC测定仪(InSituAnalyzerofDissolvedInorganicCarbon,ISA-DIC),并在实验室、室外水池和海上对其进行性能测试。主要研究内容和结果如下: (1) 以分光光...Dissolved inorganic carbon (DIC) is one of the four parameters characterizing the oceanic CO2 system, and also the basic data for the research of ocean carbon cycle and ocean acidification. So far, most of the DIC data is obtained mainly by analyzing bottle samples collected in cruise. This data is of low spatial and temporal resolution and can not meet the requirement of the research community. T...学位:理学硕士院系专业:海洋与环境学院_环境科学学号:2262010115138

Methods: The clinical data and peripheral blood were col- lected from 630 participants (314 LEAD cases and 316 normal controls) in Han population of Minnan. The 9 SNP genotypes in the ABCA1 gene were detected by Sequenom MassArray. Results: Among the 9 SNP genotypes, rs2980083 was rejected because it wash' t in accordance with Hardy-Weinberg equilibrium. Obvious linkage disequilibrium was found between rs2066714 and rs2066715, rs1800976 and rs2246293, rs2246293 and rs2980083, and rs1800976 and rs2980083 (D' 〉 0.9 ,r2 〉 1/3). There were no significant differenees ( P 〉 0.05 ) in 6 haplotypes of ABCA1 gene groups between the LEAD eases and the normal controls. No significant differ- ences ( P 〉 0.05 ) were found in frequency distribution between the LEAD cases and the normal controls in 8 SNP according to the re- sults of genotype statistics. There was no onset risk of LEAD according to the gene logistie regression analysis. Conelusion: The SNPs of rs10124755, rs2980083, rs1800976, rs4149341, rs2066714, rs2066715, rs2066716, rs2230808 and rs2246293 might not eorrelate with the susceptibility of LEAD in Han population of Minnan.2013年度南京军区医学科技创新课题(编号:MS098
