目的:研究肥胖者的规律性运动对胃部蠕动的影响关系,通过数值定量分析,建立肥胖者规律性运动对胃部蠕动的定量分析模型,为预防和治疗肥胖导致的综合症提供依据。方法:在规律性运动状态下,通过对运动参与者进行持续性运动,观察其生理指标。整个运动过程中,通过胃蠕动功能实现外界O2与血红蛋白的结合,然后经由心血管系统实现运动做功,进行胃部蠕动指标测试。结果:规律性运动下,肥胖症的胃部蠕动频率HR和胃部蠕动幅度HC显著性差异P0.01;测试组TG与对比组CG2进行对比,DP,PP,MAP的显著性差异P0.05,对肥胖者而言,以每天坚持有咕噜运动1~3 h为最佳,1 h以下,运动对胃部蠕动无效果,3 h以上,容易导致人体疲劳,且随着时间增多,胃部蠕动导致的脂肪燃烧基本不再增加,所以,规律性运动应控制在每天1~3 h为最佳。结论:建立健康的生活方式,通过规律性运动,促进胃部蠕动,通过合理营养,积极锻炼,善于调节心理压力,保持稳定情绪,改善肥胖者健康状况。 相似文献

目的:分析住区绿蓝色景观暴露与老年人精神健康相关关系中不同锻炼参数的媒介效应。方法:基于横断面设计,在绿蓝色景观暴露为自变量,健康指标为因变量的二变量Logistic回归模型中调整不同锻炼参数所引起健康指标变化的风险度(OR值)和显著性水平,确定需要重点关注的锻炼参数。结果:老年人整体健康、情绪和压力状况与锻炼类型相关性较强(OR均1,情绪状况P0.1,压力状况P0.05)。调整三个锻炼参数时,频率的OR变化幅度最高,P值显著性最强。相比于绿色景观,蓝色景观质量自评与老年人整体健康的相关性更强(调整前OR1,P0.05,分别调整频率、强度、类型参数时,OR均1,P0.05或0.1)。结论:老年人日常进行身体锻炼可充分利用低强度的自主意识性锻炼,适度提高绿蓝色景观暴露频率来改善精神健康。住区公共休闲活动空间应重视水体景观营造,虽然初期投入较大,对老年人而言具有长远的精神健康效益。 相似文献

Aresearch group led by Prof. ZHAI Qiwei from the Institute for Nutritional Sciences under the CAS Shanghai Institutes for Biological Sciences has discovered that even relatively low doses of resveratrol--a chemical found in the skins of red grapes and in red wine--can improve the sensitivity of mice to the hormone insulin, according to a report in the October,2007 issue of Cell Metabolism. As insulin resistance is often characterized as the most critical factor contributing to the development of Type 2 diabetes, the findings“provide a potential new therapeutic approach for preventing or treating” both conditions, the researchers said. 相似文献

This study examined how students who had no prior experience with videoconferencing would react to the use of videoconferencing as an instructional medium. Students enrolled in seven different courses completed a questionnaire at the beginning of the semester and again at the end of the semester. Students at the origination and remote sites did not differ in their reactions toward videoconferencing but there was a significant difference for gender. Women reacted less favorably to videoconferencing. Compared to the beginning of the semester, students reported significantly less positive attitudes toward taking a course through videoconferencing at the end of the semester. There were no significant differences in students' attitudes toward videoconferencing across courses at the beginning of the semester but there were significant differences across the courses at the end of the semester. The results suggest the need for better preparation for both students and instructors. 相似文献

A computer-mediated group is a complex entity whose members exchange many types of information via multiple means of communication in pursuit of goals specific to their environment. Over time, they coordinate technical features of media with locally enacted use to achieve a viable working arrangement. To explore this complex interaction, a case study is presented of the social networks of interactions and media use among members of a class of computer-supported distance learners. Results show how group structures associated with project teams dominated who communicated with whom, about what, and via which media over the term, and how media came to occupy their own communication niches: Webboard for diffuse class-wide communication; Internet Relay Chat more to named others but still for general communication across the class; and e-mail primarily for intrateam communication. Face-to-face interaction, occurring only during a short on-campus session, appears to have had a catalytic effect on social and emotional exchanges. Results suggest the need to structure exchanges to balance class-wide sharing of ideas with subgroup interactions that facilitate project completion, and to provide media that support these two modes of interaction. 相似文献

Electronic data interchange (EDI) provides means for interorganizational communication, creates network externalities, requires an advanced information technology (IT) infrastructure, and relies on standards. In the diffusion of such innovations, institutional involvement is imperative. Such institutions contain governmental agencies, national and global standardization organizations, local government, and nonprofit private organizations like industry associations. The last type of organizations we call intermediating institutions. They intermediate or coordinate ("inscribe") the activities of a group of would-be adopters. Unfortunately, little is known of how these organizations shape the EDI diffusion trajectory. In this article we examine one specific type of intermediating organizations?industry associations?and how they advanced the EDI diffusion process in the grocery sectors of Hong Kong, Denmark and Finland. We identify six institutional measures, placed into a matrix formed by the mode of involvement (influence vs. regulation) and the type of diffusion force (supply push vs. demand pull), that can be mobilized to further the EDI diffusion. Industry associations were found to be active users of all these measures to varying degrees. Their role was critical especially in knowledge building, knowledge deployment, and standard setting. Furthermore, institutional involvement varied due to policy and cultural contingencies and power dependencies. 相似文献

With great care, Dr. ZHOU Zhonghe takes out a package wrapped by cotton tissue from a drawer and says: "This is the gem of our collections: the fossil of a bird that lived 125 million years ago!" Then, pointing at a tiny mound, he explains: "Look, this is the claw and that is the head. It was in the egg shell and ready to hatch ... The species fell into a family of waterside inhabitants." 相似文献

This essay focuses on universal service and the Internet as means to support social and political participation. The emphasis on access to telecommunications systems in conventional approaches to universal service is contrasted with access to content. A model of the information environment is described that accounts for the roles of content and conduit, both of which are necessary conditions to achieve true access. A method is outlined for employing information indicators to observe or measure the information environment. 相似文献

The increasing prospects of digital piracy has prompted the perceived need by electronic publishers to adopt technical systems of protection, and governments to reform their copyright laws. This article is a preliminary study of the management of intellectual property by electronic publishers, defined as those involved in the production of online databases, and CD-ROMs. It focuses on three main issues: (1) how electronic publishers view the increasing threat of piracy; (2) the methods of protection employed to protect intellectual property in digital format; and (3) the importance of technological protection of intellectual property in electronic publications. The analysis is based on a sample of 23 UK electronic publishers. The interviews revealed an interesting assortment of protection methods and did not show that technological protection was a preferred way. Instead, the means of protection, in addition to copyright law, comprised niche markets, pricing, trust, bad publicity, and nontechnical and technical means. 相似文献
