日本现代漫画出版研究

漫画作为一种信息传播和娱乐的媒介正越来越发挥重要的作用 ,尤其在青少年身上这种作用表现得更为明显。日本是漫画的出版大国 ,其漫画出版的影响已经大大超越了本国的范围。漫画的输出 ,其实也是一种文化的输出。日本漫画的输出在世界范围内产生了一定的影响 ,尤其对亚洲国家 ,特别是对中国的青少年产生了不小的影响。今天 ,尽管日本的现代漫画取得了惊人的发展 ,但由于在题材上反映暴力、早恋、色情、犯罪以及美化侵略战争等的内容很多 ,对青少年产生了许多不良的影响。因此 ,我们有必要对日本的现代漫画进行全面而又深入的研究     

关于需求价格弹性理论中两个问题的探讨

A novel wearable measurement system for ambulatory assessment of joint loading in the occupational setting

It is know that biomechanical overexposure of the joints is an important cause of occupational injuries. This paper presents a novel wearable measurement system for automated assessment of joint loading in the occupational setting. The wearable measurement system consists of a full body inertial sensor motion capture system which can be worn under the clothes and shoes instrumented with 3D force sensors (ForceShoes). Promising results have been found for the performance of the inertial sensor system and the ForceShoe, separately. Validation experiments are in preparation in which the performance of the combined measurements system will be tested in the laboratory by comparing the assessed joint loading to the joint loading assessed by a conventional state-of-the-art lab-based method.     

Effect of resistance-exercise training on cognitive function in healthy older adults: a review

Several studies have demonstrated that exercise helps reduce or prevent cognitive deterioration among older adults, and recent studies have further examined the effects of resistance-exercise training on cognition. The purpose of this review was to examine the role of resistance-exercise training on cognition in healthy older adults. Specifically, it describes the definition, health benefits, and the design of resistance-exercise training. The authors also review the research related to resistance exercises and cognition and found that this exercise modality may enhance specific cognitive performances. Next, they examine the potential mechanisms underlying resistance exercise and cognitive enhancement. Finally, they consider potential therapeutics and recommendations for further research on resistance-exercise training and cognition in older adults.
