Currently, from the statistical analysis of accidents at home and abroad, the number of automobile defects and the resulting automobile accidents are very large. Obviously, the automobile defects have become one of the main factors affecting traffic safety, and risk assessment as an automobile key technical defect of risk management, the elimination of defects and reduce automobile accidents are of great significance. Through statistical study of automobile defect recall, this paper analyzes the automobile defects and its risk characteristics and the event tree analysis (ETA) method was introduced to determine the risk flow route of automobile defects. Based on thousands of automobile breakdown cases for risk probability forecast, this paper proposes a three-dimensional matrix risk assessment model of automobile defect. According to the dispersibility of automobile, a risk forecast method based on the Weibull distribution is established. The results indicate that on gathering actual failure data from after-sales service, the Weibull distribution model has a favorable applicability for forecasting risk possibility, and then apply it to auto defect in three-dimensional matrix model so as to get the overall risk level of defect automobile.

An Introduction to the Mobile Payment Market and Trend in China

Guozhong Li ASCONS 2019 INTERNATIONAL JOURNAL OF EMERGING MULTIDISCIPLINAR Vol.3 No.1

Digital payment in China is undergoing dramatic development due to the rapid growth of social networks and e-commerce platforms which has transformed the way people communicate and transact around the world. The Alipay payment and Wechat payment (Tenpay) service have been extremely popular among the customers and merchants because of the features of these services which are faster, cheaper, safer and more convenient than traditional payment services with nearly 470 million mobile payment service users in 2016. The development of China's digital payment market also led to the diversification of business models which has boosted customers shopping styles that are challenging the traditional business models and financial systems. The development of China's mobile payment market also expanded the scope of financial inclusions by establishing mobile payment ecosystems. This research indicates the possible reasons that explain the different phenomenon between coastal provinces and less developed provinces in China.

A Study on Patent Valuation Factors

Guozhong Li,Seong-Taek Park ASCONS 2017 INTERNATIONAL JOURNAL OF EMERGING MULTIDISCIPLINAR Vol.1 No.2

The purpose of this study is to examine the factors of patent value evaluation at home and abroad, and to derive common factors of patent evaluation. Since different factors are used to evaluate the value of a patent by each institution, the evaluation results differ from institution to institution. Therefore, we examined the evaluation models of two Korean institutions and three evaluation models overseas institutions. Through this, we derive the patent valuation factors which are commonly used by 5 institutions. The derived factors are expected to be useful for future patent valuation.

Experimental Study on the Deformation of a Cut-Off Wall in a Landfill

Guozhong Dai,Jia Zhu,Yang Song,Shujin Li,Guicai Shi 대한토목학회 2020 KSCE JOURNAL OF CIVIL ENGINEERING Vol.24 No.5

To effectively solve the leakage problem of landfill leachate, it is necessary to establish a vertical cut-off wall around the landfill site for seepage control. To accurately analyze the deformation of the cut-off wall, a 1/8-scale landfill cut-off wall miniature model is designed and fabricated. The actual force of the cut-off wall is simulated by filling sand on the outer side of the model wall. Meanwhile, a nonlinear finite element model of the wall is established using the ANSYS to simulate the deformation of the seepage wall. The results show that the cut-off wall made from a polyvinyl alcohol-bentonite-fly ash-cement (PBFC) anti-seepage slurry has a high ultimate bearing capacity, and its ultimate strain is approximately 5%, which is much higher than the limit strain of the actual force conditions of the cut-off wall. The horizontal displacement of the cut-off wall is approximately linear and decreases gradually from the top to the bottom, and no reverse displacement is observed. The main stress of the wall is smaller than that of the slurry, and there is no tensile stress. The simulated results are similar to the measured values of the cut-off wall, which indicates the accuracy of the simulation analysis.

Exposure Assessment Model of the Cadmium Ion in Textiles

Guozhong Huang,RuiGuo,Xiao Yang 보안공학연구지원센터 2016 International Journal of Hybrid Information Techno Vol.9 No.6

Textile products due to the industrial design will be left wide variety of chemical substances, when human contact with these chemicals can cause acute injury or chronic cumulative, so the research of exposure assessment of textile products is necessary. Due to cadmium is harmful to human health,we select the cadmium ion as the research object. In this paper, samples from some cities in Shandong were cadmium ion detection, analysis of data and derived their form of distribution. By drawing on the EU recommended harmful chemicals exposure assessment methods, we established a textile heavy metal exposure assessment model, and completed the application and verification. From the result of using this model to assess the amount of cadmium expose to human, we found that could have a bad effect on human body.

Effect of Rumen-protected Choline Addition on Milk Performance and Blood Metabolic Parameters in Transition Dairy Cows

Xu, Guozhong,Ye, Jun'An,Liu, Jianxin,Yu, Yueying Asian Australasian Association of Animal Productio 2006 Animal Bioscience Vol.19 No.3

This work was conducted to study the effect of rumen-protected choline (RPC) addition on milk performance and blood metabolic parameters in transition dairy cows. In Experiment 1, fourteen Chinese Holstein dairy cows were supplemented with 0 or 20 g/d of RPC from 7 d before expected calving to 21 d post partum. Feeding of RPC tended to increase milk yield and milk protein percentage, while milk fat and lactose percentage were not changed. Plasma concentrations of glucose tended to increase as cows consumed RPC, while plasma concentrations of triglycerides, very low density lipoproteins, cholesterol and nonesterified fatty acids were not significantly different between the two groups. In Experiment 2, thirty-six Chinese Holstein dairy cows were supplemented with 0, 30, 60 or 90 g/d RPC from 15 d before expected calving to 15 d post partum. Feeding of RPC tended to increase yield of milk and 4% fat-corrected milk for all the lactating cows, and milk composition was similar among the four groups. Plasma concentrations of glucose were remained at a higher level in 30 or 60 g/d RPC-supplemented groups, and nonesterified fatty acids were decreased in the 30 g/d group. Concentrations of triglycerides tended to reduce in 30 and 90 g/d RPC-supplemented animals, and cholesterol was reduced in 0 or 30 g/d group. These results suggest that RPC addition tended to increase milk yield and improve blood metabolic parameters during transition dairy cows, and feeding 30 g/d of RPC may be the optimal.
