武陵源风景区体育休闲旅游产业开发优势与对策

采用文献资料和考察分析等方法，对武陵源景区开发体育休闲旅游产业进行了调研。研究表明：作为旅游胜地的武陵源风景区在开发体育休闲旅游项目上有着良好的自然、人文旅游资源优势及产品开发和旅游基础设施条件。在体育休闲旅游产业开发过程中要突出旅游资源和多民族特色，科学地选择开发项目，精心设计产品形象，加大宣传与促销，以及加强对人才的培养与引进。     

体育活动对离退休综合症的干预模式研究

随着老龄化进程的发展,老龄人群体数目越来越庞大,而离退休人员是老龄人群体中的重要组成部分,目前,离退休综合症是离退休人员中普遍存在的一种心理生理疾病,其产生的根源是多方面的,既有社会家庭的影响因素,也有老年人群体的自身因素,而体育活动作为一种有效手段,对离退休综合症有良好的干预和改善作用,从体育学角度出发,研究体育活动对离退休综合症的干预模式,并提出相应的应对措施,以期为老年人健康养老,科学养老提供一定的参考。     

代谢综合征与运动干预对中心性肥胖影响的研究进展

代谢综合征（metabolicsyndrome,MS）是一系列代谢异常成分在同一个体聚集的临床综合症状,中心性肥胖是其重要的发病危险因素和临床表现之一。此外,有诸多研究显示中心性肥胖还是胰岛素抵抗（insulinresistance,IR）的一个重要发病基础。中心性肥胖症患者实施运动干预,对MS、IR有着显著的影响。本文通过文献资料法就中心性肥胖的危害和运动干预对中心性肥胖的影响进行综述。     

引入病毒传播方向聚类的攻击容忍扫频方法

攻击容忍系统通过对病毒入侵路径和频率进行扫频实现对病毒的挖掘,传统的扫频方法采用相位和频率特征匹配方法进行,对网络病毒非规则方向入侵不能起到较好的掩盖作用,扫频效果不好。提出一种采用病毒传播方向聚类分析的攻击容忍系统扫频方法,构建病毒传播路径分析模型,建立病毒传播的方向性空间搜索属性序列,分析病毒传播方向聚类演化模型,实现对病毒传播和入侵传播方向聚类过程的建模,求解病毒传播方向的聚类属性的信息熵,实现攻击容忍扫频改进算法。实验结果表明,算法能有效实现对病毒传播和扩散的时间和频率等信息进行扫频分析,病毒时频特征得到有效挖掘,通过扫频检测准确率较传统该方法提高13.6%。     

Association of Elevated Serum Uric Acid with the Components of Metabolic Syndrome and Oxidative Stress in Abdominal Obesity Subjects

Abdominal obesity (AO) and metabolic syndrome (MetS) are associated with the cardiovascular disease and type 2 diabetes. Serum uric acid (SUA) is often elevated in subjects with the AO. We aimed to investigate the association of elevated SUA with the components of MetS, oxidative stress and TG/HDL-C ratio in AO subjects. This cross-sectional study used data from a Health Survey for Prevention of Hypertension and Type 2 Diabetes Mellitus in residents of two districts in Phitsanulok province, including 443 subjects. Anthropometric, blood pressure (BP) and biochemical variables were measured. We categorized the participants to two-group as 248 AO subjects (median age = 58, interquartile range 50.0–65.0 years) and 195 non-AO subjects (median age = 53, interquartile range 47.0–62.0 years). Waist circumference was significantly correlated with SystBP, DiastBP, Glu and SUA (P < 0.05) and SUA was significantly correlated with Glu, TG, HDL-C and TG/HDL-C ratio (P < 0.05). By using multiple logistic regression, we found the association of elevated SUA with abdominal obesity, hyperglycemia, hypertriglyceridemia, reduced HDL-C, elevated TG/HDL-C ratio, MetS and increased oxidative stress after adjusting for their covariates. Our study demonstrated that circulating UA is a major antioxidant and might help protect against free-radical oxidative damage. However, elevated SUA concentrations associated with oxidative stress, MetS, insulin resistance, and components of MetS. Then, SUA may be a marker of increased oxidative stress, insulin resistance and MetS, implying an increased risk of vascular disease and T2DM.

桂林七星公园建设低碳景区的对策探析

近年来低碳旅游逐渐成为旅游新热点,注重低碳旅游景区建设有利于低碳旅游的良好发展。七星公园作为桂林山水与文化的典型代表,具备建设低碳旅游景区的自然及人文基础。通过实地调研,发现七星公园在低碳景区建设方面存在环保设施使用率低、疏于维护,部分设施安排不合理,环境保护不全面等问题。应该通过优化公园布局、开发低碳旅游产品与项目、建设低碳环保设施、强化低碳景区管理,满足现阶段旅游市场和游客对低碳旅游的需求,建设成为低碳景区。

The Burden of Teaching Teachers: Memoirs of Race Discourse in Teacher Education

This paper presents the views and educational experiences of two African American female scholars, from a critical race and black feminist theorist perspective, teaching in the area of social justice to predominantly white female pre-service teachers. These testimonies reveal the struggles encountered by these scholars when engaging students in a historical and contemporary examination of race, privilege, and systemic inequalities. The objectives of this paper are to expand on the literary dialogue of such resistance and attempt to bring awareness into the arenas that need the most exposure, i.e. departmental, faculty, and tenure review meetings. It is commonly written and verbalized that institutions are interested in attracting and retaining faculty of color. We argue that the ways we are supported must shift. This problem of student resistance, who they resist and why, should become open for discussion on college campuses across the nation. Dawn G.
