1学龄前儿童体力活动研究的10大问题显示文摘本文目的是回顾与3~5岁儿童体力活动有关的重要研究问题。本文将从三个主要研究领域进行分析:健康效果、体力活动模式、干预和政策。研究的主要问题包括:确定体力活动的健康效果,确定体力活动对保持健康体重的影响,探明体力活动对学习和行为习惯的影响,以及静坐行为对健康的影响。与体力活动模式相关的研究问题包括3~5岁儿童满足现有体力活动推荐量的情况;影响体力活动的社会和环境因素,包括家庭、幼儿园、社区环境;体力活动如何对学龄儿童期、青少年时期和成年以后产生影响。关于干预和政策方面的研究问题包括确定在家庭、保育机构、社区环境最有效的促进体力活动的干预策略,以及不同幼儿适用的干预方案;确定有效的干预手段和宣传策略;制定有效的能够增加幼儿体力活动水平的国家、州、地方和机构的政策。总之,全面了解体力活动对3~5岁儿童健康的影响,以便于掌握该群体的体力活动特点,探索如何促进幼儿的体力活动。Russell R.Pate Jennifer R.O'Neill William H.Brown Kerry L.McIver Erin K.Howie Marsha Dowda 2015北京体育大学学报2015,38,6:19
2New models for chronic disease management in the United States and China显示文摘In the United States(US)the role of the general practitioner in primary care is changing rapidly as the team leader in the new“Patient-centered Medical Home”model of care that is designed to improve the management of chronic disease.The“Collaborative Care Model”is an integrated model of treating multiple medical and behavioral conditions.These new approaches include a nurse case manager who serves as the key point of contact to provide education,facilitate treatment adherence,and guide the patient to improvements in nutrition and physical activity that cause obesity and chronic disease.A gap analysis was conducted comparing the US and Chinese general practitioner models for providing care to patients with chronic diseases.The results of the analysis were used to make recommendations for adding components of these models that are feasible and effective for Chinese general practitioners in community health centers.Ronald R.O’Donnell 2014Family Medicine and Community Health2014,2,4:5
3采用有限元分析法量化不同中空玻璃边缘密封的热位移显示文摘间隔条和玻璃板片之间的相对热位移是中空玻璃边缘密封乃至中空玻璃(IGU)本身老化的主要原因之一。作者采用有限元分析法(FEA),建立了发生在大尺寸(1.5 m×2.1 m)的中空玻璃边缘密封的热位移与温差变化之间的模型,这是三种商业化的、不同材质的、不同设计的间隔条,在温度变化为-30^+60℃范围内的模型。此模型是基于铝间隔条和镀锌钢间隔条与尼龙插角的搭配,不锈钢间隔条和弯曲插角的搭配。尼龙插角假定为实心的并稳固地固定于间隔条上;弯曲插角被建模成实心弯曲的金属插角,并同样稳固地固定于间隔条上。由于实际的弯曲插角是空心的,模型可能高估了这种转角设计的应力。正如预期那样,在低温时,插角会被向内拉,导致弯曲角度大于90°;在高温下,插角会被向外推,导致弯曲角度小于90°。通过检测发生在中空玻璃周边第一道密封的聚异丁烯密封胶厚度的变化,作者发现,到目前为止,不锈钢间隔条对于截面积的变化影响最小;铝制间隔条的影响最大。这个发现与基于间隔条材料与浮法玻璃之间热膨胀系数差异而预期的性能一致。因此,热位移引起的第一道密封的有效扩散横截面变化,可以解释为何具有不同间隔条材料的中空玻璃之间的性能差异。James E.Stewart William R.O’Brien Andreas T.Wolf 李宏伟 周文亮 王文开 范琴 马作栋 2007玻璃2007,34,2:3
4Introduction to special edition:The challenge of chronic non-communicable disease and the opportunity for transforming health care through primary care based population health management显示文摘China shares with the United States an epidemic of chronic,non-communicable disease,with rising rates of cardiovascular disease and metabolic disorders in particular.The rising prevalence of these conditions results in great human suffering,lost productivity,high utilization of medical services and associated health care costs[1].The first section of this special edition,“The Chronic Disease Challenge for General Practitioners”highlights the extent of this problem in China.The study by Wu and Jian[2]duplicated the results of other studies showing high prevalence of hypertension,low patient awareness and lack of treatment.Strand et al.[3]found high prevalence of cardiovascular and metabolic conditions in post-menopausal women.Both of these articles noted the lack of readily available preventive and community health resources,a finding echoed in the article by Huang et al.Ronald R.O’Donnell 2015Family Medicine and Community Health2015,3,1:3
