运动员运动神经损伤后,会导致运动神经部位肌肉萎缩,运动员伤后恢复的关键是防止肌肉萎缩,使神经部位肌肉得到营养,治愈肌营养不良症。提出了器械心理混合再生疗法治疗肌营养不良症,从而最终治愈运动员由神经损伤而导致的肌肉萎缩。根据受伤运动员的不同肌肉萎缩病症,采用运动器械辅助、减少运动量、改变训练部位、结合心理治疗等步骤,以达到治疗目的。该方法在2010年1月至2011年12月对112例由于运动神经损伤造成的肌营养不良受伤运动员,进行自身治疗前后对照研究,观察使用器械心理混合再生疗法12个月后受伤运动员的徒手肌力、MBI以及FMA变化。实验结果表明:使用器械心理混合再生疗法后69.6%的受伤运动员肌力有所改善,生活活动能力和下肢运动功能有所提高,本方法具有一定的实际应用价值。 相似文献

运动损伤后的最佳救助对于运动员的后续运动恢复能力影响极大,损伤救助的难点在于如何根据运动员的实际情况,提供最佳的救助方案。传统的救助方法采用经验和表面现象判断的方法,无法对运动员的实际情况,无法达到最佳救助,且临场方法风险大。提出一种基于最佳测试分析(OTA)测评指导的最佳损伤救助方法,采用最佳测试分析方法,对每个运动员的多项身体指标进行监测和分析,提取表征运动员身体状况的多项指标,并选择与之对应的最佳损伤救助方案,提高救助效果。采用实际的损伤运动员进行测试分析,实验结果表明,采用基于OTA测评指导的方法进行损伤救助,损伤救助的效果明显好转,具有很好的应用价值。 相似文献

传统的体操运动员颈椎损伤急救方法大多采用经验判断的方法,个人主观性判断占很大因素,无法对受伤体操运动员的颈椎病情进行全面监测和治疗;提出一种基于恢复系数的体操运动员颈椎损伤恢复性救助方法,采用恢复系数指标来评价体操运动员受伤后的恢复程度,将伤员颈椎的恢复时间分为3个阶段:初期急救、中期治疗与后期恢复。在每个阶段,通过一系列的评分制度对伤员颈椎的恢复情况进行打分,最终计算出伤员颈椎当前阶段的恢复诊疗情况,根据受伤体操运动员的得分情况对体操运动员的恢复情况进行相应的等级评定;以931例伤员为对象进行比对分析,结果显示,基于恢复系数的体操运动员颈椎创伤急救方法能够指导大部分伤员恢复到完全恢复阶段,具有很好的指导意义。 相似文献

A research 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 in red wine-can improve the sensitivity of mice to the hormone insulin according to a report in the October issue of Cell Metabolism.…… 《中国科学院院刊(英文版)》2008,22(1):14-15
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

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

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

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
