Cooperation Performance between E-Commerce and Sports Commodity based on Online Marketing Strategy
Yadong Ren 보안공학연구지원센터 2016 International Journal of Multimedia and Ubiquitous Vol.11 No.1
With the rapid development of internet and information technology, adopting internet platform will provide new advantage for companies, especially for sporting goods business. In recent years, most sports enterprises build their own online sales platform, enhance customer loyalty and improve its competitive advantages by using efficient B2C distribution platform. In this paper, we make empirical analysis of the factors that will affect the brand loyalty, the result shows that: (1) from the correlation analysis, the platform trust and platform satisfaction has a significant correlation with the brand loyalty; (2) from the regress analysis, the coefficient is -0.865, t is 3.801 and Sig. is 0, the result shows that platform satisfaction has significant positive effect on platform loyalty. On this basis, we put forward the related suggestions to improve the network marketing of sports commodity.

With the development of information technology, Internet age has changed the way of people's life in learning, entertainment, communication, consumption and other areas. Network has a positive effect on study and life for college student, but also brings a lot of negative impact. In this paper, we test the influence of internet content and try to find out how it could impact the college students’ sports life. By using empirical analysis, the result shows that the main reason of college students' motivation to participate in sports activities is to have a strong physique, there is a significant correlation between the Internet and college students' sports life style. Internet will significantly affect the sports consumption and sports interest of college students. On this basis, we put forward some advices.

This study aims to investigate the magnitude and distribution of welding residual stresses in orthotropic steel decks stiff ened with U-shaped ribs. Numerical simulation of the welding residual stresses is performed using the thermal elastic–plastic fi nite element method. The residual stresses are subsequently measured using the hole-drilling strain-gage method. Based on the results of this study, it can be determined that: (1) The longitudinal welding residual stresses ( σ z ) in the weld zones are tensile stresses, where the peak value exceeds the minimum yield strength ( f yl ); however, relatively low compressive stresses exist in the areas located far away from the welds; (2) The stress gradient in the weld zone is steep, and the widths of the areas experiencing tensile stress are narrow; (3) In the case of the upper surface of the deck, the weld that is fi rst deposited has the highest peak stress, while similar stresses are determined for the remaining welds. In the case of the lower surface of the deck, the peak stress in the weld zones is greater than that on the upper surface; (4) In the case of the weld zone of the U-shaped ribs, the tensile stresses reach up to 1.15 f yl ; however, at locations a short distance away from the welds, the σ z varies from tensile to compressive, and fi nally transforms into a small tensile stress at the base of the U-shaped ribs. In addition, the simulated and measured σ z are compared, and the deviation between them is analyzed.
