Purpose: The article focuses on studying the impact of brand anthropomorphism, and brand love, on brand advocacy, and at the same time the moderate role of brand self-connection in the process of customers’ perception of the brand, especially the brand distribution. The survey subjects are customers with millennial consumers in Ho Chi Minh City, who have the behavior of buying brands in the smart mobile device industry many times with a specific brand in terms of brand distribution. Results: The findings show that Brand anthropomorphism and brand love are crucial factors to impact brand advocacy and the role of self-brand connection also is a confirmed positive effect on the relationship between brand anthropomorphism and brand love. Research design, data, and methodology: The article uses quantitative research to test the model and research hypotheses. The way to collect quantitative data is to use questionnaires with 1531 samples in Ho Chi Minh City, Vietnam. Conclusion: The research results can help businesses build a long-term brand strategy and expect to get new rewards and value from customers. They can also add to the theory about the relationship between brands and customers.
Structure and Magnetic Properties of Nd45-xCxFe30Co15Al10 Alloys
Nguyen Anh Tuan,Vu Hong Ky,Nguyen Huy Dan,Luu Tien Hung 한국물리학회 2008 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.52 No.5
Nd45-xCxFe30Co15Al10 (x = 0, 1, 3, 5 and 7) alloys were prepared by using a copper mold suction casting method. X-ray diraction (XRD) patterns show a trend of increasing crystallinity with increasing C content. In addition, crystallites with dierent shapes and sizes are observed by using scanning electron microscopy (SEM) and high-resolution transmission electron microscopy (HRTEM). Multi-phase properties of the alloys are clearly exhibited on the magnetic measurements. The hysteresis loops of the lower C content alloys (x = 1 and 3) show a single-phase hard magnetic behavior with coercivities of 6.2 kOe while the loops of the higher C content alloys (x = 5 and 7) are supposing a multi-phase property with coercivities up to 7.2 kOe. Two magnetic-phase transitions, depending on the C concentration, appear in the thermomagnetization curves. Addition of C at low content (1 to 3 at.%) can improve the hard magnetic behavior of the Nd-(Fe, Co)-Al alloy.

Fe90−xNixZr10 (x = 0, 5, 10, 15, 20 and 25) ribbons with various thicknesses were prepared byusing a melt-spinning technique. The Curie temperature, TC, of the alloys dramatically decreasedfrom 960 K to room temperature at high quenching rates. When the alloys had an amorphousstructure, their TC strongly depended on the Ni concentration. The maximum entropy change,|Sm|max, with H = 12 kOe, of the alloys was around 1 J·kg−1K−1 at room temperature. Onthe other hand, the full width at half maximum the entropy-change peak was quite large, 85 K,which was suitable for applications in magnetic refrigerators at room temperature.
The Multidimensional Masculinity in Nguyễn Huy Thiệp’s Short Stories
( Van Thuan Nguyen ),( Anh Dan Nguyen ),( Van Luan Nguyen ) 부산외국어대학교 아세안연구원 2024 Suvannabhumi Vol.16 No.1
Nguyễn Huy Thiệp is a pillar in Vietnamese cultural life after the Second Indochina War, and the fates of men and women at the beginning of Đổi mới (Renovation) is one of the prominent themes in his short stories. To show off sexual power, seek glory, and maintain his dominant position, Thiệp’s heroes engage in a game of oppressing the weak, hunting animals, and harassing women. However, due to the complex changes in social life, moral values, and gender inequality, men in the postwar period quickly experienced the feeling of humiliation, impotence, and failure. In turn, the sophisticated aspects of masculinity demonstrate the cultural and ethical concerns of contemporary Vietnamese society. By exploring the multidimensional nature of masculinity expressed in Thiệp’s stories, this study aims to resolve misconceptions about gender and the relationship between men and women in his work.

The outbreak of the COVID-19 pandemic has had a significant impact on the Vietnamese economy. In the midst of a complex disease that compelled people to limit their interaction, customers’ shopping habits shifted from “offline” to “online” transactions. Mobile payments have also grown in popularity. The goal of this study is to figure out what factors influence the use of mobile payments by hotel clients in Can Tho after COVID-19. The research team also examines how those factors influence customers’ willingness to use mobile payment and makes recommendations to better the current situation. Primary data was collected from 227 persons using online surveys and processed with SPSS software for this study. To analyze the correlation relationship between the elements determining the intention to use, the Cronbach alpha, EFA, Correlation, and Regression methods used to assess the scale are applied. Perceived Trustworthiness, Perceived Usefulness, and Perceived Ease of Use all have positive effects on customers’ propensity to use, according to the findings. Perceived Security, on the other hand, has no bearing. The findings of this study have significant theoretical and practical implications for the development of mobile payment services in Can Tho, particularly following the implementation of COVID-19.

This paper explores the effectiveness of spin motion in mitigating the flight dispersion of a two-stage solid-propellant rocket model due to thrust misalignment. The aerodynamic coefficients of the rocket model are obtained by the use of a panel method and semi-empirical equations. A simulation program is developed to solve the equations of motion while considering the variations of the inertial parameters. Monte Carlo simulation techniques are applied to provide statistical data that are used to analyze the relationship between the spin motion and flight dispersion. The spin motion is generated by canting the fins to generate the axial aerodynamic moment. The results show that thrust misalignment at the first stage of the rocket has a great impact on the dispersion of rocket flight. By canting the first-stage fins at a relatively large angle to create the spin motion right after launch, the dispersion area of the payload-release location can be minimized considerably. However, thrust misalignment as well as the fin cant angle at the second stage appear to have insignificant effects on the rocket flight trajectory. On the other hand, canting the fins of the second stage at a large angle may lead to an increase in the spin rate, which may be harmful to the rocket operation. The paper also shows the variation of the dispersion characteristics of rocket flight when the fin size is modified.
