Purpose: This study's purpose is to conduct empirical research on online comments affect Vietnamese consumers' impulsive buying in e-distribution. This study also considers affecting of browsing toward the urge to buy, and the urge to buy toward impulse buying in e-distribution. Research design, data and methodology: This study used the non-probability method to assemble data from 273 customers' online buying experiences via a Google Forms online survey. By using SmartPLS, the data were examined for reliability, convergent validity, discriminant validity of the variables, and proposed hypothesis testing. Results: The empirical study discovered that internet comments with utilitarian and hedonistic values had a positive effect on browsing, the urge to buy, and impulse purchases in e-distribution. Additionally, the result revealed that browsing had a positive influence on the urge to purchase. Likewise, the findings also disclosed that the urge to buy had a favorable effect on impulse buying. Conclusions: This study offered a thorough conceptual model of internet feedback influencing browsing, urge to buy, and impulsive purchases in e-distribution. Also, to increase impulsive buying, this study will assist e-distribution managers in concentrating on developing innovative marketing strategies and action plans that take into consideration consumers' internet reviews, browsing, and urge to buy.

For any integer k $\geq$ 2, let P(c, k + 1;q) be the number of all k+1-tuples with positive integer coordinates ($a_1,a_2,...,a_{k+1}$) such that $1{\leq}a_i{\leq}q$, ($a_i,q$) = 1, $a_1a_2...a_{k+1}{\equiv}$ c (mod q) and 2 $\nmid$ ($a_1+a_2+...+a_{k+1}$), and E(c, k+1; q) = P(c, k+1;q) - $\frac{{\phi}^k(q)}{2}$. The main purpose of this paper is using the properties of Gauss sums, primitive characters and the mean value theorems of Dirichlet L-functions to study the hybrid mean value of the r-th hyper-Kloosterman sums Kl(h,k+1,r;q) and E(c,k+1;q), and give an interesting mean value formula.

The emergence of Internal has established a huge virtual exchange market, and the innovative e-commerce has changed a way of distributing goods and services. This paper concerns the issues of customer's loyalty to maintain the customer retention between individual and Internet shopping mall. We use the concept of customer's perceived value, satisfaction, and trust, in order to explore and explain the formation process of customer loyalty. A survey data has been collected through the hep of internet research institution. A statistical analysis shows that a subset of customer's perceived value has positive Impact on satisfaction, which in turn has also positive influence on trust, Increasing the level of customer's loyalty. We also provide a brief discussion of strategic guidelines about analytic results.

This paper is a study on a model of economic value of transmission speed of Internet Commerce. For this research, this paper searches the factors that influence the transmission speed of Internet and suggests the model for measurement of economic value. The model adopted in this research is CVM(contingent valuation method) using in environment economics and the research area in this paper is concentrated on Internet-based Electronic Commerce. For this purpose, this paper suggests econometrics model that measures customer's payment intention for transmission speed of Internet. This model can be used as the basic tool of feasibility of investment analysis and reasonable pricing on Internet service. For the more, it will be followed empirical study and more careful comprehension for objective validity of this study.

East Asian region, specifically China, Japan, and Korea, is considered as an area of advanced mobile handsets and mobile services. The well-established infrastructure of this region is well known due to rapid introduction of diverse feature-equipped handsets and advanced capabilities of mobile network operators. However, the status of mobile business has rarely been dealt with in previous studies. In this paper, we compare mobile value chains among these three countries. China has adopted open platform for mobile data services while Korea and Japan's mobile network operators control mobile portals for accessing diverse contents and services. We also discuss some possible reasons for the differences among the three countries in terms of value chain structures.

Since e-learning is conducted based on the learner's autonomy, motivation to continuously participate is crucial for success in e-learning. As the number of adult learners participating in lifelong education increases, it is necessary to study learner participation and the motivating factors. Drawing upon the Expectancy-Value Theory and Self-Regulated Learning Theory, this study analyzed the influence of motivational factors (value, costs, cognitive regulation, and scheduling) on learner participation. An e-learning program was implemented on MoodleCloud, and learners completed a survey before going through the program. Regression analysis was conducted using the survey response data along with the participation score, calculated using the log data. The results of the analysis demonstrated that value and scheduling significantly influenced learner participation, with gender differences found in value. This means that as adult learners perceive higher value in the e-learning program and possess better scheduling skills, they are more likely to participate. These findings can be utilized in developing teaching and learning strategies for both learners and instructors, ultimately helping to prevent dropout in e-learning.

Based on the literature on customer's repeat purchase intention, customer's repeat purchase intention was explored, customer's repeat purchase intention has been a crucial factor influencing consumer behaviors, In this research, the development of models on repeat purchase intention repurchase was indicated. Based on the electronic commerce platform, we focus on the customer's repeat purchase intention on silk products, This paper mainly explores the e-commerce purchase frequency (EPF), customer perceived value (CPV), perceived risk of e-commerce (EPR), and customer satisfaction (CS). The influence of the four factors on repeat purchase intention (RPI) is investigated. In the results, we found that CPV and CS have positive correlations with repeat purchase intention, The EPR has a negative correlation with RPI and has no significant influence on RPI. The result can provide meaningful suggestions for silk product retailers.

Automative system and robot are operated by motor. Recently, automative system and robot need correct operation and control for precise task. Therefore they need precise motor control technology. In present, controller needs precise motor control technology in automative system and robot. Usual step motor driver that has 200 steps per revolution is not proper. So we need micro step motor driver that is more precise then usual step motor driver. In this paper, micro step motor driver is used for precise control of step motor. The goal is precise operation and location control. This micro step motor driver is A3972SB that is made in Alloegro Company. It has serial port that receives two 6-bits linear DAC value. Almost all systems generate DAC value with micro processer and ...

In order to determine the monomer reactivity ratio in copolymerization of acrolein, the copolymerization of acrolein with styrene, methyl methacrylate and vinyl acetate respectively was studied. The Q and e value of acrolein in each copolymerization were also calculated from those of monomer reactivity ratios, but the calculated values were slightly different from each other. The Q and e of acrolein for the system of acrolein-styrene copolymerization were Q = O.64 and e = O.62 respectively. Relations among the Q and e value, the composition and structure of copolymers and the mean sequence length in copolymerization were also discussed for acrolein copolymers.

Radial variation of crystalline state in a stem of Chamaecyparis obtusa E. was examined by x-ray diffraction analyses. Relative crystallinity and degree of crystallite orientation showed significant differences between juvenile and adult wood. That is, Relative crystallinity increased with increasing the age from pith to about 20th annual ring, after which it reached a more or less constant value. On the other hand, degree of crystallite orientation decreased outward from pith to about 10 years and presented almost a constant value thereafter. Crystal width by Scherrer's equation did not show any significant differences between juvenile and adult wood. Therefore, it was considered that crystallinity index and degree of crystallite orientation by x-ray diffraction method could be used for evaluating wood quality.
