The Development of Questionnaire on the Motivation of College Students` participation in Tennis
( Xiao Chuan Yin ),( Ke Li ) 한국체육학회 2015 국제스포츠과학 학술대회 Vol.2015 No.1
Purpose: As the world`s second largest professional sports, tennis is played by quite many people around the world including college students. And as the main group playing the tennis, college student plays an important role in popularizing tennis, and could be the pioneer of developing Chinese mass tennis. This research is aiming at developing the Questionnaire on the Motivation of College Students` Participation in Tennis, so that the reason why college students play tennis could be measured more precisely. To be further, the motivation of college students in Beijing will be measured so as to know more about the reason why college students play tennis. Thus, suggestions could be offered to bring more and more college student to play tennis as well as to make the one who is already take part in the sport get much more fun to be willing to take part in sports lifelong. Method: The Questionnaire on the Motivation of College Students` Participation in Tennis is developed based on literature and interview. 240 college students were tested. T-test、exploratory factor analysis (EFA) and correlation analysis was used to test the validity and reliability. Result: Five factors were got after common factor analysis, and there are significant correlations between the factors(0.379~0.678, p<0.01 ). Also there are significant correlations between the factors and the total points (0.625~0.857, p<0.01 ). The questionnaire`s Cronbach αof the population is 0.936. The Cronbach αof the factors is above 0.800. The split-half reliability of the motivation of undergraduate about tennis sport is 0.889. All the split-half reliability among the factors is above 0.800. Conclusion: Firstly, The Questionnaire on the Motivation of College Students` Participation in Tennis includes five factors and 29 items. The five factors are: enjoyment, external influence, learning, emotional experience and value expression. Secondly, With high reliability and validity, the Questionnaire on the Motivation of College Students` Participation in Tennis can be used to measure the motivation of college students` participation in tennis. Thirdly, There are significant differences between the gender and grades on external influence, learning and emotional experience but no on the enjoyment. Significant differences also showed between the different majors on value expression.
Stereo-digital image correlation in the behavior investigation of CFRP-steel composite members
Xiao-Yuan He,Yun-Tong Dai,Hai-Tao Wang,Tian-Yuan Ge,Gang Wu,Jian-Xiao Wan,Shuang-Yin Cao,Fu-Jun Yang 국제구조공학회 2017 Steel and Composite Structures, An International J Vol.23 No.6
The application of carbon fiber reinforced polymer (CFRP) in steel structures primarily includes two categories, i.e., the bond-critical application and the contact-critical application. Debonding failure and buckling failure are the main failure modes for these two applications. Conventional electrometric techniques may not provide precise results because of the limitations associated with single-point contact measurements. A nondestructive full-field measurement technique is a valuable alternative to conventional methods. In this study, the digital image correlation (DIC) technique was adopted to investigate the bond behavior and buckling behavior of CFRP-steel composite members. The CFRP-to-steel bonded joint and the CFRPstrengthened square hollow section (SHS) steel column were tested to verify the suitability of the DIC technique. The stereo- DIC technique was utilized to measure continuous deformation. The bond-slip relationship of the CFRP-to-steel interface was derived using the DIC data. Additionally, a multi-camera DIC system consisting of four stereo-DIC subsystems was proposed and applied to the compressive test of CFRP-strengthened SHS steel column. The precise buckling location and CFRP delamination of the CFRP-strengthened SHS steel column were identified. The experimental results confirm that the stereo-DIC technique can provide effective measurements for investigating the behaviors of CFRP-steel composite members.
Application of Graphics Originality in Advertising Design

Graphics originality is the basic way of design thinking. It also provides some effective techniques for design practice. Today, advertising design can make full use of various graphics originalities, thus ad can have great visual effect and achieve their goals. This essay will discuss the importance of graphics originality by analyzing specific ad design cases in the base of graphics originality means. And this essay may help to widen the thoughts of advertising originality and design.
Numerical investigation of heat transfer enhancement in a channel with periodically oblique plates
Yin Xiao Zhan(잔인샤오),Tae Seon Park(박태선) 대한기계학회 2011 대한기계학회 춘추학술대회 Vol.2011 No.10
Heat transfer enhancement and the self-oscillatory behavior of the flow in a channel with periodic oblique plates are studied numerically. The length and the tilt angle of oblique plate are changed to investigate the heat transfer and flow evolution. The computational results show the characteristics of flow and heat transfer for different lengths and tilt angles of the plate. The object of this study are expected to lead to guidelines that will allow the selected oblique plate geometry configuration for designing heat exchanger which increase thermal performance.

The purpose of this study is to explore the interaction of virtual reality consumption pattern under the background of virtual reality, and the influence of such interaction on consumers' purchase intention. In this paper, we selected three independent variables (including content interaction, function interaction and service interaction) and two mediating variables (including perceived quality and perceived value) to explore the relationship between them and consumers' purchase intention, used SPSS24.0 and AMOS24.0, made the analysis of reliability and validity, constructed the structural equation model, and tested the hypotheses. The findings show that: fourteen hypotheses are all true, and the perceived value of virtual reality has a positive influence on consumers' purchase intention. In addition, we find that the perceived value has a mediating effect in this study.
Degrees of Freedom for Complex MIMO Multiple-Way Relay Channel

The amount of diversity or the number of degrees of freedom (DOF) can be increased by multiple antennas in wireless communication systems. In this paper, we study the DOF of multiple-input multiple-output (MIMO) multiple-way relay channel. There are two groups of source nodes and several one relay node which are equipped with multiple antennas in this kind of channel. Each source node in one group exchanges independent message with the source node in the other group via the relay node. We first show the upper bound on the total DOF for this channel. Then we extend it to the complex MIMO multiple-way relay channel and present the corresponding upped bound.
