“互联网+”背景下农村公共体育服务有效供给研究

采用文献资料法和实地调查法,对\"互联网+\"背景下农村公共体育服务有效供给进行研究。研究发现:供求信息不对称造成供需错配,同质化、低水平供给范式使老百姓的满意度与获得感下降;当前\"互联网+\"技术在农村公共体育服务中运用条件已经具备,应利用网格技术促进农村公共体育设施合理配置,创建移动APP客户端,建立互联网考核机制等。国家社会科学基金项目(16BTY021);;福建省哲学社会科学重点项目(FJ2015A009

Expression of uPARAP/ Endo180 and Its Clinical Significance in Nasopharyngeal Carcinoma

[中文文摘]目的:探讨尿激酶型纤维蛋白溶酶原激活剂相关蛋白(uPAR-associated protein，uPARAP/Endo180)、uP-AR和VEGF在鼻咽癌组织中的表达及临床意义。方法:采用免疫组化SP法检测58例鼻咽癌组织和30例慢性鼻咽炎组织中uPARAP、uPAR和VEGF蛋白的表达,分析其与鼻咽癌临床病理特征的关系。结果:鼻咽癌组织中uPARAP的阳性表达见于肿瘤间质的成纤维细胞和巨噬细胞,定位于胞膜和胞质,呈棕黄色颗粒状分布;uPAR阳性染色定位于肿瘤细胞与间质细胞胞浆内;VEGF阳性染色定位于肿瘤细胞胞浆内。鼻咽癌组织中uPARAP、uPAR和VEGF的阳性表达率分别为75.9%、81.0%和77.6%;与慢性鼻咽炎比较,uPARAP、uPAR和VEGF在鼻咽癌组织中的阳性表达率有显著性差异(P<0.05);鼻咽癌组织中uPARAP表达与uPAR、VEGF的表达水平呈明显正相关(P<0.05);uP-ARAP在角化型鳞癌、非角化型癌和未分化癌的阳性表达率分别为42.9%、66.7%和86.1%。随着肿瘤组织类型分化程度的下降,uPARAP表达水平有上升趋势(P<0.05)。不同组织学类型之间进行两两比较发现, uPARAP 的表达也有显著性差异( P<0.05) 。uPARAP 蛋白的表达与鼻咽癌组织病理分级、颈部淋巴结转移、临床分期密切相关( P<0.05),而与患者的年龄、性别等因素无关。结论: uPARAP、uPAR 和VEGF 在鼻咽癌组织中协同表达对促进鼻咽癌的扩散转移可能起重要作用, 联合检测这些指标有望成为判断鼻咽癌恶性程度和估计患者预后的重要生物学标志。[英文文摘]Objective: To investigate the expression and clinical significance of uPARAP/Endo180(uPAR-associated protein), urokinase plasminogen activator receptor(uPAR) and vascular endothelial growth factor(VEGF) in nasopharyngeal carcinoma(NPC). Methods: Streptavidin-horseradish peroxidase immunohistochemistry(SP-IHC) method was used to detect the expression of uPARAP, uPAR and VEGF in 58 samples of NPC and 30 samples of chronic nasopharynxitis. Results: The positive expression of uPARAP in NPC was mainly confined to mesenchymal cells, including fibroblasts and macrophages. The uPARAP immunoreactivity was found as granulated diffuse cytoplasmic staining, as well as in a pattern suggesting localization on the cell surface. uPAR in NPC tissues was evenly distributed in the cytoplasm of both cancer cells and mesenchymal cells. The expression of VEGF in NPC was mainly seen in the cytoplasm of tumor cells. In the NPC tissues, the expression rate of uPARAP, uPAR and VEGF was 75.9%, 81.0%, and 77.6%, respectively (P<0.05). A significant difference was found in the expression of uPARAP, uPAR and VEGF between NPC tissues and chronic nasopharynxitis tissues. The expression of uPARAP was positively correlated with the expression of uPAR and VEGF in NPC. The positive expression rate of uPARAP was 42.9% in keratinizing NPC, 66.7% in non- keratinizing NPC, and 86.1% in undifferentiated carcinoma.The expression of uPARAP was associated with the differentiation of NPC. The expression of uPARAP was significantly different among different pathological types of NPC(P<0.05). The expression of uPARAP in nasopharyngeal carcinoma was significantly correlated with pathological classification, tumor grade, cervical lymph node metastases and clinical.福建省自然科学基金资助(编号:C0610045

The Influence Model of Flow of Chinese Traditional Sports

从沉浸的角度探讨影响我国民族传统体育行为意向的主要因素。通过对我国东、中、西部典型地区民族传统体育活动情况进行抽样调查并采用相关分析和回归分析等方法对沉浸模型进行检验,发现我国民族传统体育的行为意向受多种因素的共同影响。我国民族传统体育组织规范、注重过程目标、注重形式、内容充实、意义丰富、建立内在动机、综合发展等因素促进沉浸行为意向的形成。同时,沉浸是我国民族传统体育发展中所追求的理想状态,影响沉浸的各因素之间也存在交互的影响作用。From the perspective of flow,this paper discussed the major factor of influencing the behavioral intentions of Chinese traditional sports.Through the sample investigation on the research of traditional sports in the east,west and middle of China,and the use of correlation and regression analysis and other methods to test models of flow,the author found that behavioral intention of Chinese traditional sports has been influenced by the combined effect of many factors.Chinese traditional sports have organizational norms,focusing on process goals,form,full of content and rich sense,and establishing intrinsic motivation,integrated development and other factors to promote the formation of behavioral intentions flow.Meanwhile,the flow is the ideal state we are pursuing in the development of Chinese traditional sports.There are interactions between the factors.国家社会科学基金资助项目(07CTY004);中央高校基本科研业务费专项资金资助项目(ZK1001);宁波市社会科学带头人资助项目(G11-XK03);浙江省之江青年社会科学学者资助项目(ZJQN2011G007

covert channel based on igmpv2

目前IP组播技术应用越来越广泛,其应用的协议是IGMP,该协议不断完善,版本不断升级,安全性也得到了提高.但是,在目前应用最广的IGMPv2中,可以实现隐蔽通道,最明显的是协议包中的&quot;路由器检测选项&quot;字段和&quot;最大响应时间&quot;字段.该文主要针对如何使用这两个字段实现隐蔽通道加以讨论.介绍了隐蔽通道和IGMP的基本概念,说明了该隐蔽通道的实现原理,描述了软件设计,最后对该方法进行了分析

complex covert channel detection based on chain analysis methodology

在研究隐蔽通道的检测方法时,可以将隐蔽通道分成两大类:单一隐蔽通道和复合隐蔽通道.复合隐蔽通道具有了跨越多主机的特点,简单的主机入侵检测体系结构很难对此进行检测,而数据融合技术可以有效地解决这个问题.文中提出了基于数据融合思想的链路分析法,并对复合隐蔽通道的特点、链路分析法检测复合隐蔽通道的理论以及软件的设计进行描述
