2007年厦门市湖里区伤害监测结果分析

[目的]了解厦门市湖里区伤害病例发生的情况,为制订干预措施提供科学依据。[方法]用分层随机抽样方法,抽取二级、三级医院各1所为哨点监测医院。[结果]全年共监测病例36 845例,男∶女为2.3∶1;导致伤害前3位依次为钝器伤(32.6%)、刀/锐器伤(24.9%)和跌倒/坠落(22.3%);主要为生产运输设备操作及有关人员(35.2%)、商业服务业人员(15.3%)和办事和有关人员(12.2%);伤害主要发生在5～10月(56.9%);日发生的高峰时间为7～12时和17～20时(61.0%)。[结论]青壮年是伤害防治的重点人群,预防和控制职业伤害是干预的重点,加强生产安全保护措施和创造安全的环境是主要的预防措施

A case-control study of risk factors for low birth weight infants in Xiamen City

目的探讨厦门市低出生体质量儿的发生及其危险因素,为预防和降低低出生体质量儿的发生提供科学依据。方法采用1∶3配对病例-对照方法,在厦门市属医疗机构收集86例低出生体质量儿及按匹配条件收集258例对照,利用条件lOgISTIC逐步回归模型分析其影响因素。结果母亲文化程度在大专及以上、家庭月人均收入≥4 000元、孕前1年至孕13周内补充叶酸、饮食清淡和产检次数≥5次是保护因素,而妊娠期高血压疾病、孕期服用抗生素、孕周4 000 yuan,intake of folic acid a year before pregnancy to the first three months of pregnancy,balanced diet,and more than 5times of antenatal examinations.The risk factors of LBW infants included hypertensive disorder complicated with pregnancy,intake of antibiotics,gestational age less than 37 weeks,increase in amplitude of gestational BMI<5,father was worker or technician,and eating raw garlic more than 2times per week.Conclusion The above causes may contribute to low birth weight infants in Xiamen City and appropriate preventive measures should be taken to reduce the incidence.福建省科技厅自然科学基金面上项目(No.2012D046); 厦门市科技局科技计划项目(No.3502Z20124057); 湖里区科技局(No.12社09

社会转型与文化转型·海峡两岸圆桌论坛·实录

徐新建(四川大学教授、人类学高级论坛副秘书长):大家好。今天的话题围绕"文化转型"展开。据我所知这既是人类学圈的一个新提法,也是一个有争议的话题。我想请徐杰舜教授首先交代一下议题的来源和这次圆桌对话的意义。虽然在座有部分学者参与谋划了很久,但多数人是没有参与的。今天上午周大鸣教授做了简短的表态,强调提"文化转型"的目的是一种抗争,也就是人类学和社会学的抗争,后者提出的"社会转型"几乎主导了现实社会的思想和实践。我想,这已涉及了知识生产和学术政治,值得各位关注。下面就请徐杰舜老师做简要说明

JUNO Sensitivity on Proton Decay p→νˉK+p\to \bar\nu K^+ Searches

The Jiangmen Underground Neutrino Observatory (JUNO) is a large liquid scintillator detector designed to explore many topics in fundamental physics. In this paper, the potential on searching for proton decay in $p\to \bar\nu K^+$ mode with JUNO is investigated.The kaon and its decay particles feature a clear three-fold coincidence signature that results in a high efficiency for identification. Moreover, the excellent energy resolution of JUNO permits to suppress the sizable background caused by other delayed signals. Based on these advantages, the detection efficiency for the proton decay via $p\to \bar\nu K^+$ is 36.9% with a background level of 0.2 events after 10 years of data taking. The estimated sensitivity based on 200 kton-years exposure is $9.6 \times 10^{33}$ years, competitive with the current best limits on the proton lifetime in this channel

JUNO sensitivity on proton decay p → ν K + searches*

The Jiangmen Underground Neutrino Observatory (JUNO) is a large liquid scintillator detector designed to explore many topics in fundamental physics. In this study, the potential of searching for proton decay in the $p\to \bar{\nu} K^+$ mode with JUNO is investigated. The kaon and its decay particles feature a clear three-fold coincidence signature that results in a high efficiency for identification. Moreover, the excellent energy resolution of JUNO permits suppression of the sizable background caused by other delayed signals. Based on these advantages, the detection efficiency for the proton decay via $p\to \bar{\nu} K^+$ is 36.9% ± 4.9% with a background level of $0.2\pm 0.05({\rm syst})\pm$$0.2({\rm stat})$ events after 10 years of data collection. The estimated sensitivity based on 200 kton-years of exposure is $9.6 \times 10^{33}$ years, which is competitive with the current best limits on the proton lifetime in this channel and complements the use of different detection technologies
