动画片对培养3～6岁幼儿道德品质的影响     

苏青清 《大众科技》2013,(5):322-324

动画片是当今幼儿成长的好伙伴,动画片中可爱的卡通人物形象、滑稽的角色表演,孩子们喜欢的故事情节,都让每个孩子成为了动画片的忠实粉丝。儿童期是一个人思想道德品质形成的重要时期,3～6岁的幼儿正处在这个关键年龄段,从小培养孩子的道德品质是极为重要。现如今,幼儿对动画片的喜爱程度和看动画片的时间都比以前更加深入了,很多动画片里的人物成为了孩子们口中津津乐道的对象,动画片的内容已成为了幼儿相互交流的重点,而3～6岁孩子具有好模仿的特点,因此,动画片的卡通人物就成为了幼儿竞相模仿的对象。动画片早已是最适合孩子接受的一种文化、教育和娱乐形式,并潜移默化地影响着幼儿对世界的最初认知、对美与丑的感受、对善与恶的判断。由此可见,动画片的内容和中心思想,以及人物的言行举止等都对培养幼儿良好的道德品质的影响不可低估。  相似文献

An evaluation of personalised insoles developed using additive manufacturing     

Andre S. Salles  Diane E. Gyi 《Journal of sports sciences》2013,31(4):442-450

Abstract

The aim of the study was to evaluate the short and medium term use of personalised insoles, produced by combining additive manufacturing (AM) with three-dimensional (3-D) foot scanning and computer aided design (CAD) systems. For that, 38 runners (19 pairings) were recruited. The experimental conditions were: personalised and control. The personalised condition consisted of trainers fitted with personalised glove fit insoles manufactured using AM and using foot scans to match the plantar geometry of the feet. The control condition consisted of the same trainers fitted with insoles also manufactured using AM but using scans of the original insole shape. Participants were allocated to one of the experimental conditions and wore the trainers for 3 months. Over this period they attended three laboratory sessions (at months 0, 1.5 and 3) and completed an Activity Diary after each training session. The footwear was evaluated in terms of discomfort and biomechanics. Lower discomfort ratings were found in the heel area (P ≤ 0.05) and for overall fit (P ≤ 0.05), with the personalised insole. However, discomfort was reported under the arch region for both conditions. With regard to the biomechanical data, differences between conditions were detected for ankle dorsiflexion at footstrike (P ≤ 0.05), maximum ankle eversion (P ≤ 0.05) and peak mean pressure under the heel (P ≤ 0.01): the personalised condition had lower values which may reduce injury risk. The personalisation of the geometry of insoles through advances in AM together with 3-D scanning and CAD technologies can provide benefits and has potential.  相似文献   

Spike jump biomechanics in male versus female elite volleyball players

ABSTRACT

There are well-known biological differences between women and men, especially in technical-coordinative variations that contribute to sex differences in performance of complex movements like the most important offensive action in volleyball, the spike jump. The aim of this study was to investigate sex-dependent performance and biomechanical characteristics in the volleyball spike jump. Thirty female and male sub-elite volleyball players were analysed while striking a stationary ball with maximal spike jump height. Twelve MX13 Vicon cameras with a cluster marker set, two AMTI force plates, surface EMG, and a Full-Body 3D model in Visual3D were used. Main findings include sex differences (P< .05) in jump height (pη² = .73), approach [speed (pη² = .61), step length], transition strategy [plant angle, neuromuscular activation (pη² = .91), horizontal force maxima and impulses], acceleration distances [centre of mass displacement (pη² = .21), minimal knee and hip angles], use of torso and arms [incline, angular velocity (pη² = .23)]. Correlations support that the results cannot be explained fully by strength and power differences between sexes but represent the product of technical-coordinative variations. Their relevance is acknowledged for both sexes and numerous performance determinants displayed sex differences. The integration of such attributes into sex-specific training seems promising but its effect requires further investigation.  相似文献

Nd_2O_3-NdF_3-LiF熔盐电解槽温度分布研究     

郑鑫  朱卫花  彭光怀  韩宝军  张小联 《赣南师范学院学报》2012,(6):19-21

针对3KA电解槽温度实际分布研究的不足,通过设计实验装置实际测量了Nd2O3-NdF3-LiF熔盐电解槽内温度分布,并对其外部影响因素进行了分析.研究结果表明:电解槽内温度纵向分布是从上到下先升高再下降,横向分布是从阴极到阳极先下降再升高,电解过程中电化学反应主要集中在电解槽的中部,热量是影响温度变化的主要因素.  相似文献
