Research on Preparation Methods of Ultrafine Softwood Powder
Changsheng Fan,Dongxia Yang,Hongling Wang,Yan Sun,Hua lou,Hongru Yang 보안공학연구지원센터 2016 International Journal of u- and e- Service, Scienc Vol.9 No.4
Pine wood sawdust is used as raw materials for experimental processing into ultrafine wood powder. Sizes of ultrafine wood powder particles serve as a standard for measuring ultrafine processing. The core part of the experimental processing equipment is the millstone which can exert great shear force and grinding force on strong fiber materials so as to ensure the successful preparation of ultrafine particles. The “equilibrium orbit” model is used to simulate processed superfine particles in calculating separation performance. Moreover, the CFD is chosen for simulating separation performance of wood powder particles with different sizes in the two-phase flow field, so as to ensure the successful separation and grading of wood powder particles with different sizes in the practical processing. Research is made on physical properties of collected wood powder as samples with different sizes and influence on composite material properties when ultrafine wood powder is taken as padding. Research on ultrafine wood powder provides meaningful experimental data and theoretical support for the future research on micro-nano fibrils.

Modern education technology has changed the teaching mode, and brings a huge impact to physical education. With the development of multimedia technology, the impact of network education is unprecedented, not only changes the teaching content and teaching methods, but makes the fundamental reform of the modern education system. In this paper, we test the correlation of red sports culture and modern physical education by using network data. The result shows that after red sports cultural has been integrated; college student’s outlook on life, values and world outlook has a very significant increase, and it will enhance innovative thinking ability of college student. So that, network education has formed a new growth point, and will become the main direction.

Comprehensive Analysis of the Wushu Education Performance and Multimedia Teaching in College
Wei Dongyi,Lu Qingwu,Liu Dan,Fan Hongling,Long Xiaodong 보안공학연구지원센터 2015 International Journal of u- and e- Service, Scienc Vol.8 No.12
With computer-assisted instruction is widely used in university education, Multi-media teaching has produced a new form of education. Multimedia teaching has the effect of interactive and dynamic multi-dimensional, which enhances the students' learning interest and the understanding. In this paper, we make an empirical analysis about the impact of Wushu education on college students .The result shows that after using multimedia teaching, Wushu teaching can improve the physical function of college students, it will significantly improve the college students' sports view, sports value and sports motivation. At the same time, multimedia teaching can effectively improve the teaching quality. On this basis, we put forward relevant suggestions.

The effective mechanism of the polysaccharides from Panax ginseng on chronic fatigue syndrome
Wang, Jia,Sun, Chengxin,Zheng, Yan,Pan, Hongling,Zhou, Yifa,Fan, Yuying 대한약학회 2014 Archives of Pharmacal Research Vol.37 No.4
Ginseng acidic polysaccharide WGPA isolated from the root of Panax ginseng C. A. Meyer was fractionated into WGPA-A and WGPA-N by anion-exchange chromatography. The antifatigue activity of ginseng acidic polysaccharide WGPA has been reported in our previous research. This present study was designed to identify its active component and elucidate the mechanism for preventing chronic fatigue syndrome (CFS). WGPA, WGPA-A and WGPA-N were orally administered to mice once daily for 15 days. The effects of these compounds on physiological biomarkers of oxidative stress and on the morphology of the mitochondria in striated skeletal muscle were assessed. The results of forced swimming test-induced indicated that WGPA and WGPA-A could lengthen the swimming time, while WGPA-N could not. In addition, malondialdehyde and lactate dehydrogenase levels in serum were enhanced; while those of superoxide dismutase and glutathione peroxidase were lowered. Interestingly, the structural degeneration of mitochondria were all ameliorated. These findings suggested that WGPA-A is the active component of WGPA, it might have potential therapeutic effects for CFS and the oxidative stress might be involved in the pathogenesis. Our results also provided essential data for a better understanding of the antifatigue effects of P. ginseng extracts.
