预约模式下的病房床位协同管理研究

病床是大型医院关键的医疗资源,随着住院患者数量日益增长,病床资源的合理配置已成为医院管理者亟待解决的难点。以厦门大学附属第一医院(总院)为例,在统计医院现有病床资源的基础上,分析病床配置合理性,研究病床预约排队算法和调度规则,研发病床协同预约管理系统,提高了医院床位的使用率与周转率,提升了医院总体管理水平。福建省医学创新课题(软科学)—预约下的病房床位协同管理研究(编号:2015-CXB-R1)~

基于社会资本视角的企业活动分析

本文从由人际关系构成的社会资本出发,用两企业博弈的模型说明企业使用社会资本的原则及其特点,指出通过非规范的社会资本配置资源将导致交易费用的上升,外部负效应增大。随着市场和企业的发展,企业将逐步摆脱对经营者人际关系的依赖,最终实现对社会资本的现代化改造,建立起独立于人际关系的企业自身生产经营的社会网络体系,形成企业自我独立的发展能力。教育部博士点基金(批准号:03JB790032);; 福建省社会科学研究规划项目(批准号:2003T088)资助

基于HSV颜色空间的视频镜头检测

为了克服光线变化和运动对视频镜头检测的影响,本文提出了一种新的视频镜头检测算法. 该算法把视频图像从RGB 颜色空间映射到HSV 颜色空间,再重新量化图像的H 与S 分量到127 个色度区域,最后通过比较帧间图像在色度区域的重叠程度来检测镜头的变化. 同时采取有效的虚假镜头分割分析机制以减少图像快速变化的影响. 实验结果表明,本算法具有较高的准确率和查全率,并且有较快的处理速度,在视频镜头分割检测领域具有一定的实用价值.国家863 计划项目(2006AA01Z129) 国家自然科学基金(60672018) 厦门大学“985”二期信息创新平台项目(00002X07204

Analysis on the epidemiological characteristics of the sporadic cases with hepatitis E infection in the rural area in Jiangsu province

目的了解江苏省农村散发性戊型肝炎的流行病学特征。方法通过建立覆盖市、镇、村三级医疗卫生服务机构的疑似肝炎主动监测网络,系统全面地监测戊型肝炎病例的发病情况。结果主动监测网络的敏感性明显高于网络报告系统,能更加准确、全面地掌握戊肝的发病规律。结果显示戊型肝炎病例占疑似急性肝炎病例的26.7%,男性戊肝发病率高于女性(P<0.01);发病随着年龄增长而上升,多见35岁以上人群;全年均有发病,冬春季节较高;戊型肝炎病毒株HEV1、4型并存,但以HEV4型为主(92.5%)。结论疑似肝炎主动监测系统数据显示目前戊肝发病率有被低估的风险。To understand the epidemiological characteristics of the sporadic cases with hepatitis E infection in the rural area of Jiangsu province,the prevalence of hepatitis E infection was surveyed systemically and completely through the initiatively monitoring system for the suspected cases of hepatitis E covering the city,town and village levels of medical and health service organizations.It was found that the initiatively monitoring system for suspected hepatitis E cases reflected the incidence of hepatitis E more accurately and comprehensively and was proved to be more sensitive than the network reporting system.The cases with hepatitis E accounted to 26.7% of the suspected cases with acute hepatitis and they were more frequent in male than in female.The incidence of hepatitis E increased with advance of age and most of cases occurred with age over 35.Estimated incidence was stable on the whole year,but rose up in winter and spring.The HEV type 1 and type 4 co-existed,but the HEV type 4 was proved to be the main type(92.5%).From the above observations,it seems that the initiatively monitoring system for the suspected cases of hepatitis E may be under-estimated for the risk of the hepatitis E infection in rural area of Jiangsu province.国家高技术研究发展计划(863计划)(2006AA02A209)资

中国海及邻近区域碳库与通量综合分析

中国海总面积约470万平方公里,纵跨热带、亚热带、温带、北温带等多个气候带.其中,南海北依\"世界第三极\"青藏高原、南邻\"全球气候引擎\"西太平洋暖池,东海拥有全球最宽的陆架之一,跨陆架物质运输显著,黄海是冷暖流交汇区域,渤海则是受人类活动高度影响的内湾浅海.中国海内有长江、黄河、珠江等大河输入,外邻全球两大西边界流之一的黑潮.这些鲜明的特色赋予了中国海碳储库和通量研究的典型代表意义.文章从不同海区（渤海、黄海、东海、南海）、不同界面（陆-海、海-气、水柱-沉积物、边缘海-大洋等）,以及不同生态系统（红树林、盐沼湿地、海草床、海藻养殖、珊瑚礁、水柱生态系统等）多层面对海洋碳库与通量进行了较系统地综合分析,初步估算了各个碳库的储量与不同碳库间的通量.就海气通量而言,渤海向大气中释放CO2约0.22Tg Ca-1,黄海吸收CO2约1.15Tg Ca-1,东海吸收CO2约6.92～23.30Tg Ca-1,南海释放CO2约13.86～33.60Tg Ca-1.如果仅考虑海-气界面的CO2交换,中国海总体上是大气CO2的\"源\",净释放量约6.01～9.33Tg Ca-1.这主要是由于河流输入以及邻近大洋输入所致.河流输入渤黄海、东海、南海的溶解无机碳（DIC）分别为5.04、14.60和40.14Tg Ca-1,而邻近大洋输入DIC更是高达144.81Tg Ca-1,远超中国海向大气释放的碳量.渤海、黄海、东海、南海的沉积有机碳通量分别为2.00、3.60、7.40、7.49Tg Ca-1.东海和南海向邻近大洋输送有机碳通量分别为15.25～36.70和43.39Tg Ca-1.就生态系统而言,中国沿海红树林、盐沼湿地、海草床有机碳埋藏通量为0.36Tg Ca-1,海草床溶解有机碳（DOC）输出通量为0.59Tg Ca-1;中国近海海藻养殖移出碳通量0.68Tg Ca-1,沉积和DOC释放通量分别为0.14和0.82Tg Ca-1.总计,中国海有机碳年输出通量为81.72～103.17Tg Ca-1.中国海的有机碳输出以DOC形式为主,东海向邻近大洋输出的DOC通量约15.00～35.00Tg Ca-1,南海输出约31.39Tg Ca-1.综上,尽管从海-气通量看中国海是大气CO2的\"源\",但考虑了河流、大洋输入、沉积输出以及微型生物碳泵（DOC转化输出）作用后,中国海是重要的储碳区.需要指出的是,文章数据是基于中国海各海区碳循环研究报道,鉴于不同研究方法上的差异,所得数据难免有一定的误差范围,亟待将来统一方法标准下的更多深入研究和分析.国家重点研发计划项目(编号:2016YFA0601400);;国家自然科学基金项目(批准号:91751207、91428308、41722603、41606153、41422603);;中央高校基础研究项目(编号:20720170107);;中海油项目(编号:CNOOC-KJ125FZDXM00TJ001-2014、CNOOCKJ125FZDXM00ZJ001-2014)资

Social Net Transition and Enterprise Development——A story of an Enterprise Becoming Mature

从社会关系网络的角度出发,论证了企业从不成熟走向成熟的机制和途径。认为企业所掌握的社会关系网络可作为判断公司制企业发展是否成熟的标志;从交易成本的角度对企业生产经营过程由企业或个人掌握社会关系网络进行比较,指出企业社会关系网络由个人向企业的转变,虽然是企业发展成熟的必然过程,但在企业社会关系网络转型过程中,社会关系网络需要在个人和企业中寻求一个均衡。The article demonstrates the mechanism and approach for enterprises to mature from the perspective of social net.It is believed that the mature degree of a corporate enterprise can be judged by its social net.From the view of transaction costs,the comparison of the social net between enterprises and individuals under the production and operation of enterprises pointes out that the transition of social net from individuals to enterprises is an inevitable process with an enterprise developing maturity.However,it is necessary to seek a balance in the social net between enterprises and individuals during the course of the transition.教育部博士点基金(03JB790032)和;; 福建省社科基金(2003T088)的资
