Purpose: Yoga is originated in India 5000 years ago, until now it has become heated among global sports education. Related researches about the impacts of Yoga practice on mood state of university male students who major in sports training still do not come to light .This research tries to explore the impacts of Yoga practice on mood state of university male students who major in sports training, and to provide further refercences for Yoga teaching and scientific data for mechanism of scientific fitness according to teaching practice. Method: This research selects 96 male university students who major in sports training from class 1 to 6 in grade 2005 who take Yoga as selective course, and applies BFS Mood Survy before and after the 14th class.There are conventional teaching of 8 minutes of breath regulation, about 55 minutes of 6 body positions practice and 15minutes of supine relax in the 14th class. The BFS Mood Suvery can measure students` before and after class feelings from different levels of activeness, happiness, anger, calm, etc, based on its function of evaluation and activation, and this research uses Likert scale to evaluate final suvey answers. Result: 88 testees` data get into final result analysis and all data are put into SPSS statistic software to measure, which shows data reliability reaches 95%. The difference between before and after Yoga class is outstanding―activeness, happiness, calm, angern, excitability, depression, inactiveness, P=0.00. The experiment shows that before the class, the activeness separate survy average score is 14.68, and after Yoga class it is 16.85, which increses 14.8%. Yoga can help testees unconsciously become more energetic and remove their tension, to increse their self-confidence. Conclusion: Yoga class has great impacts on male students who major in sports training, such as helps them get more energy, relese their nervousness, avoid anger and depressed passive emotions, finally to become more confident. University male students who major in sports training can choose "body position"and "breath regulation"as the main learning contents. It is suggested that students need to choose those body positions which can do good to cardiac muscle, lung, liver and other organs, and also can effectively stimulate and balance glands of each body part, to promote the firmness and stretch of joints and ligaments. It is a recommendation that using affirmative words to remind during the teaching and it is important for students to form posive self-suggestion while practice.

Jianbin Zhang,Bo Guo,Tianxiang Zhao,Feng Sha,Fei Zhang,Qiang Li 한국화학공학회 2016 Korean Journal of Chemical Engineering Vol.33 No.6

As a new, effective CO2 fixation system, 1,2-ethylenediamine and 1,2-ethylene glycol (EDA+EG) can efficiently activate CO2 and directly convert it into a novel CO2-storage material (CO2SM) with 46.3% yield. The aqueous CO2SM solution can react with Ca(OH)2-saturated limpid solution to generate morphology-controllable CaCO3 microparticles with additional CO2 bubbling and Ca(OH)2. Additionally, the aqueous EDA+EG solution could be recycled multiple times without significant loss of CO2 capturing and releasing capabilities.

Jianbin Zhang,Yinan Yan,Yajun Gao,Wenjing Tang,Qiang Li 한국화학공학회 2016 Korean Journal of Chemical Engineering Vol.33 No.4

Silicate material prepared from high-alumina coal fly ash (HACFA) was characterized by using XRD, SEM, FTIR spectroscopy, TGA-DSC, and elemental analysis. These spectral results show that the silicate material is mainly composed of eight elements--O, C, Si, Ca, Na, Mg, Al, and Fe, which exist as the formations of Ca2+, Na+, Mg2+, Al3+, Fe3+, SiO3 2−, and CO3 2−, and some adsorbed water and crystal water are determined in the silicate material. The material with surface area of 117.12m2/g shows a faveolate structure, and a pore size distribution of silicate material is calculated at 11.01 nm from the nitrogen desorption isotherm using the BJH model. When the material was used for CO2 adsorption at T=323.15 K and flow rate=95mL/min with 15.79% (vol) CO2, a dynamic adsorption capacity of CO2 on the surface of silicate material was found at 8.67mg/g and the adsorption values decreased weakly after seventeen recycling times. The investigation of dynamic adsorption behavior shows that the silicate material presents similar adsorption properties with commercial active carbon and stronger adsorption properties than commercial diatomite.

A Fast and Robust Algorithm for Fighting Behavior Detection Based on Motion Vectors

( Jianbin Xie ),( Tong Liu ),( Wei Yan ),( Peiqin Li ),( Zhaowen Zhuang ) 한국인터넷정보학회 2011 KSII Transactions on Internet and Information Syst Vol.5 No.11

In this paper, we propose a fast and robust algorithm for fighting behavior detection based on Motion Vectors (MV), in order to solve the problem of low speed and weak robustness in traditional fighting behavior detection. Firstly, we analyze the characteristics of fighting scenes and activities, and then use motion estimation algorithm based on block-matching to calculate MV of motion regions. Secondly, we extract features from magnitudes and directions of MV, and normalize these features by using Joint Gaussian Membership Function, and then fuse these features by using weighted arithmetic average method. Finally, we present the conception of Average Maximum Violence Index (AMVI) to judge the fighting behavior in surveillance scenes. Experiments show that the new algorithm achieves high speed and strong robustness for fighting behavior detection in surveillance scenes.

The Application of Hilbert-Huang Transform in the Abnormal Vibration Analysis for Metro Vehicle

Qiuze Li,Huailong Shi,Jianbin Wang,Pingbo Wu 한국도시철도학회 2014 IJAR Vol.2 No.1

The time-frequency analysis method Hilbert-Huang Transform (HHT) is applied in the signal processing for metro vehicle, in order to analyze and research the reason of abnormal vibration of carbody floor. The linear superposition property and the actual physical meaning of marginal spectrum are demonstrated to assess the vibration characteristic of structure. The rail vehicle is a nonlinear system and unsteady process. All kinds of frequency domain analysis method based on Fourier Transform is short to study on the un-linear and unsteady system, cannot use it to search the abnormal vibration reason. HHT is an effective tool to research the nonlinear and unsteady process, describing the vibration amplitude changing process with time and frequency. Compared to the test results and considered that the abnormal vibration frequency come from the two times frequency components about the traction motor rotating speed which is transferred to the floor through the vehicle suspension system. The frequency is close to the natural frequency of local floor and stimulates local elastic vibration of the floor significantly. At last, the paper pointed that the frequency component maybe caused by the misalignment of flexible-coupling.

Rongbai Li,Jijing Luo,Yongliang Wang,Qigui Jiang,Jianbin Liu,Wei Zeng,Yindi Zeng 한국유전학회 2017 Genes & Genomics Vol.39 No.2

Rice (Oryza sativa L.) is thermophilic crop and all of its growth stages are affected by low temperature stress. However, some populations of common wild rice in Guangxi Province (China) (GXWR) can tolerate low temperature stress. To understand the molecular mechanisms underlying chilling tolerance in these wild rice resources, transcriptome sequencing was performed to study the differentially expressed genes (hereafter referred to as DEGs) between GXWR-derived chilling-tolerant chromosome segment substitution line (hereafter referred to as CSSL), DC90, and its chilling-sensitive recurrent parent 9311 under early chilling stress. Comparative transcriptomic analysis revealed 659 DEGs exclusively identified in DC90 in response to early chilling stress. Functional clustering by CARMO (comprehensive annotation platform for functional exploration of rice multiomics data) showed that majority of the DEGs were enriched in chloroplasts, suggesting a connection between chilling stress tolerance and photosynthesis regulation exists in rice. KEGG analysis of these DEGs presented a complicated chilling responsive regulatory network, including ‘phytohormone signaling’, ‘photosynthesis pathway’, ‘ribosome translation machinery’, ‘phenylpropanoid biosynthesis’, which is coordinately involved in early chilling response. Here, the identified DEGs and unveiled molecular regulatory network sheds light on deep understanding the mechanisms underlying rice chilling stress tolerance. As well, KEGG term-enriched DEGs, chilling tolerant QTLs (quantitative trait loci), and co-localized DEGs in introgression interval, will be focused for further functional investigation of the molecular mechanisms of chilling stress response in rice.

Yan Chang,Jianbin Zhang,Qiang Li,Lihua Li,Bo Guo,Tianxiang Zhao 한국화학공학회 2014 Korean Journal of Chemical Engineering Vol.31 No.12

Liquid densities and viscosities are reported for the binary system of 1,2-ethanediamine (EDA)+triethyleneglycol (TEG) at T=(298.15, 303.15, 308.15, and 313.15) K. Densities were measured using a capillary pycnometerand viscosities were determined using an Ubbelohde capillary viscometer. The experimental results are compared withdata published in the literatures. Based on the density data and kinematic viscosity data, excess molar volumes (VmE)and deviation in kinematic viscosity (Δν) were calculated and the calculated results were fitted to a Redlich-Kister equa-tion to obtain the coefficients and estimate the standard deviations between the experimental and calculated quantities. The values of VmEare negative in the whole composition range, whereas the values of Δν are positive over the majorcomposition range. From kinematic viscosity data, Gibbs energies of activation of viscous flow (ΔG*), enthalpy of ac-tivation for viscous flow (ΔH*), and entropy of activation for the viscous flow (ΔS*) were also calculated.

Shen Yongpeng,Li Yuanfeng,Liu Dongqi,Wang Yanfeng,Sun Jianbin,Sun Songnan 대한전기학회 2023 Journal of Electrical Engineering & Technology Vol.18 No.4

Electric vehicle (EV) is developed because of its environmental friendliness, energy-saving and high efficiency. For improving the performance of the energy storage system of EV, this paper proposes an energy management strategy (EMS) based model predictive control (MPC) for the battery/supercapacitor hybrid energy storage system (HESS), which takes stabilizing the DC bus voltage and improving the efficiency of the system as two major optimization goals. In addition, an enumeration algorithm is presented to solve the optimization function. The experimental results show the performance of the proposed EMS which is able to enhance the overall instantaneous power and prevent the battery from overloading. Meanwhile, compared with the results of a single battery storage system, the maximum amplitude of the battery current in the HESS is reduced by 40.81% and whole system energy loss is reduced by 24.13% with the proposed power management strategy.

Wei Yan,Jianbin Xie,Peiqin Li,Tong Liu,Xiaoguang Guo 한국산학기술학회 2013 SmartCR Vol.3 No.5

This article discusses a new algorithm for vein matching based on log-polar transform to address problems that occur with the changing of finger position and from differences between imaging devices for current vein matching algorithms. The new algorithm first extracts the feature area, which contains enough characteristics for image matching, depending on the structure of the finger vein ridge alignment. It then calculates the degree of similarity between the log-polar transform results of the model image feature areas and the sample image, and finally analyzes the result by the degree of similarity and the relationship of relative positions between feature areas. Experiments show that the algorithm is robust for rotating and zooming images of the finger vein.
