论美育对德育的促进作用

在全球化背景下学校德育面临着前所未有的挑战，文化全球化给中国青少年一代的思想意识和价值观念带来了巨大的冲击。现在中央提出了构建社会主义核心价值体系的理论构想，这一构想将是未来学校德育的重要内容。但是，如果要很好地将这样的德育内容贯彻落实到具体的学校德育中，就必须摒弃原来的功利主义的德育观，运用美育来促进德育，在美育和艺术教育中完成青少年的人格塑造，在青少年的思想意识层面构建起社会主义核心价值体系。     

Biomechanics of judo backward breakfall for different throwing techniques in novice judokas

It is generally accepted that proper learning of the breakfall technique during early judo training is essential for attenuating the risk of judo-related head injury. Therefore, it is critical to understand the kinematics and head injury risks of breakfall motion to design a more safe and effective judo teaching paradigm that results in reduction of injury risk. We aimed to investigate the biomechanics of judo backward breakfalls by comparing osoto-gari and ouchi-gari in novice judokas. Twelve male novice judokas (age: 21.3 years, SD?=?0.6 years; height: 1.74?m, SD?=?0.04?m; body weight: 71.3, SD?=?6.4?kg; body mass index: 23.5, SD?=?2.3) volunteered to participate in this study. The kinematic data of the breakfall motion for both osoto-gari and ouchi-gari were collected using a three-dimensional motion analysis technique (200?Hz). We observed significant differences between the movement patterns for the two techniques, especially in the lower extremity movements. In addition, a significantly greater peak extension momentum (osoto-gari: 1.29, SD?=?0.23?kg?m^2?s^?1; ouchi-gari: 0.84, SD?=?0.29?kg?m^2?s^?1) and lower head position along the vertical axis (osoto-gari: 0.18, SD?=?0.05?m; ouchi-gari: 0.31, SD?=?0.08?m) with a large effect size were found in the breakfall for osoto-gari. Our results suggest that a different paradigm is needed for effectively teaching each breakfall technique that will enable us to substantially lower the risk of judo-related head injuries in novice judokas.

二次学术文献编辑素质问题探讨

二次学术文献是专门搜集、梳理和检阅并控制一次学术文献的文献,其意义和价值还在于弥补一次学术文献的缺陷.二次学术文献编辑的素质要求,既有一般编辑的素质要求,更有自己的特殊素质要求.关于二次学术文献编辑素质的问题,至今还很少有人问津.作此探讨,目的是为了引起人们对此问题的关注.     

竹荪生长条件的初探

竹荪有防腐抑菌的作用,可以开发成天然食品防腐剂,但竹荪的生长速度较慢。本文探讨了竹荪的生长条件,试验结果表明：竹荪在马铃薯和麸皮培养基中,生长速度较快,生长的适宜pH值为5.50～6.00,适宜温度为25℃。     

民族传统体育的生境选择与个性生成:基于黔北“独竹漂”的论析

民族传统体育是窥视民族文化发展的窗口，其多元价值需要从不同理论视角来探究。主要运用文献资料法，在文化生态的理论框架内，从生境的角度切入，通过对黔北地区"独竹漂"这一典型个案来分析和探索民族传统体育在发展形成历程中的生境选择问题，具体从自然环境和社会环境两个维度来展开相关分析。同时，探讨了"独竹漂"这一文化事项的个性生成与所处生境的密切关联，以此阐明民族传统体育在发展过程中的生境选择问题，及其文化个性生成与生境的关系。     

多晶VO_2材料的绝缘-金属转变研究

对用粉末冶金(烧结)法制得的多晶VO_2材料进行了X-射线结构分析和R-T曲线的实验研究.结果表明,纯的VO_2多晶材料升温时在338K发生数量级约为10~3倍的绝缘-金属转变,掺杂Cr的VO_2样品转变温度向低温方向偏移。当样品中含有5％以上的V_2O_5或样品淬油时,其R-T曲线将变得平坦.

Multiscale fabrication of a transparent circulation type blood vessel simulator

We proposed and fabricated multiscale transparent arteriole and capillary vessel models with circular cross sections of 10-500 μm using photolithography. The circularities of the fabricated 10, 50, and 500 μm diameter microchannels were 84.0%, 61.5%, and 82.3%, respectively. Next, we connected these different models to realize a circulation type blood vessel model simulating arteriole networks. We proposed a novel connection method using an intermediate connector made of wax, which we used to connect these models to make a circulation model. In flow experiments, the fabricated models showed no leakage and circulation models with seamless connections were achieved.     

Quick dissection of the segmental bronchi

Knowledge of the three‐dimensional anatomy of the bronchopulmonary segments is essential for respiratory medicine. This report describes a quick guide for dissecting the segmental bronchi in formaldehyde‐fixed human material. All segmental bronchi are easy to dissect, and thus, this exercise will help medical students to better understand the bronchopulmonary segments.
