The impact of customer satisfaction on brand loyalty for mobile telecommunications services in Ho Chi Minh city
No full textThis study was aimed at investigating five factors of customer satisfaction and assessing the impact degree of each factor on brand loyalty for mobile telecommunications services in Ho Chi Minh City. Data were collected from 205 customers who have been using mobile telecommunications services in Ho Chi Minh City. The author uses a quantitative method to analyze Cronbach’s Alpha reliability, Exploratory Factor Analysis EFA and multiple linear regression analysis. The results indicated that satisfaction with services is the strongest factor affecting brand loyalty, followed by satisfaction with employees, satisfaction with distribution channels, satisfaction with enterprise, satisfaction with brand image and environment. The results are consistent with the hypothesis because services quality plays an important role in this industry’s existence. Research findings are about to build scientific basis for Ho Chi Minh City’s mobile telecom enterprises in developing customer loyalty that is a matter of urgency in all aspects of theory and practice
Le secteur informel à Ho Chi Minh-Ville
No full textThe Peripheral Sector in Ho Chi Minh-Ville. The peripheral, or informal, sector in Vietnam is still badly know. After a short historical survey, the author undertakes to outline the special characteristics of the economic system called «underground» as it concerns Ho Chi Minh-City. She thus studies the different human groups -men, women, children -who are active in this domain, before reflecting on the living conditions of these poor population groups. Finally, in conclusion, she shows the complex relationship of concurrence and complimentarity that unites these two broad sectors of activity, the formal and the peripheral, where is clearly expressed the duality and present ambiguity of this large city, progressing haltingly towards the projected phase of its development.Le secteur informel au Vietnam est encore mal connu. Après une courte rétrospective historique, l'auteur s'attache donc à dégager les spécificités de l'économie dite souterraine dans le contexte d'Ho Chi Minh-Ville. Il analyse ainsi les différents groupes humains (hommes, femmes, enfants) actifs en ce domaine, avant de s'interroger sur les conditions de vie et d'habitat de ces populations pauvres. Il montre enfin en conclusion la relation complexe de concurrence et de complémentarité qui unit ces deux grands secteurs d'activité, le formel et l'informel, où s'expriment bien la dualité, l'ambiguité actuelle, de cette grande ville en transition vers le développement.Ngoc-Du Thai-Thi.

Ho Chi Minh\u27s Ideology on revolutionary Medical Ethics
No full textPresident Ho Chi Minh, a hero of national liberation, a world cultural celebrity hasleft us a huge and extremely valuable spiritual legacy, which we have not been able to exploitthe full extent of that heritage in both breadth and depth, including his ideology on medicalethics. Researching on his medical ethics is important in improving the medical ethics ofVietnamese doctors today.The author uses the method of analysis, synthesis, and comparison of data sources to studyHo Chi Minh\u27s ideology on medical ethics. The research results show that Ho Chi Minh\u27sideology on medical ethics shows the unity between morality and politics - a characteristic inHo Chi Minh\u27s ideology, which is the revolutionary medical ethics in general and the medicalethics of the socialist doctor, including ethical standards to regulate the perception andbehavior of doctors in relation to patients, profession, colleagues, society and themselves
Successful factors in increasing customer engagement for branded Facebook pages in Ho Chi Minh City
No full textThe thesis aims to determine successful factors that marketers shall acknowledge in order to effectively increase beverage branded pages’ engagement with the customers. The case scenario is to increase customer engagement for a newly- established branded page for a beverage business, whose target customers are the millennials in Ho Chi Minh City, Vietnam. The studied literatures regarding the topics in the theoretical study of the thesis were used as the secondary information source. In the empirical study, the qualitative methodology was implemented. Through interviews with experts, the author withdraws insights and opinion which serve as the primary information source of the thesis.
The results of the thesis determine the important necessity of the four researched factors, which are the social media content, the virtual brand community, the advertisement, and the engagement metrics. The experts’ industrial insights and the theoretical background were integrated, in order to certify four factors that contribute effectively to the increase in customer engagement of a branded page for a beverage business
The real option with an absorbing barrier.
No full textCe papier analyse l'option réelle avec barrière inférieure. C'est le modèle d'un investissement irréversible soumis au risque de perdre l'option d'investir si on attend trop. La valeur critique pour investir décroit lorsque la barrière se rapproche, ou lorsque la volatilité augmente. L'incertitude a un effet ambigu sur le temps espéré de décision et sur la probabilité de résolution après N années. Les résultats numériques et analytiques s'appliquent aussi à une option financière aéricaine avec une "down-and-out barrier" sur un support payant des dividendes.option réelle, incertitude, irréversibilité
Application of XGBoost Model for Predicting the Dynamic Response of High-Speed Railway Bridges
No full textThe dynamic response at high speed affects both the vehicles and the structures in a complex manner, especially in the railway infrastructure problems. In this study, we developed a new KD-Railway tool for analyzing the dynamic behavior of high-speed railways by using the finite element method. Then, extreme gradient boosting (XGBoost) was used to predict and better understand the dynamic response of high-speed railway bridges. The model was trained and tested using a dataset including properties and dynamic responses of 10,000 bridges generated by KD-Railway. The input variables were the bridge span length, the flexural rigidity, mass per length of the bridge, the cross-section area of bridge decks, the train speed, the damping ratio, and the HSLM train models. On the other hand, maximum vertical deflection and maximum acceleration were considered as the output parameters. The coefficients of determination (R2) for these two outputs were (0.996, 0.931, 0.977) and (0.987, 0.901, 0.962) for the training, testing, and entire dataset, respectively. The sensitivity analyses were also conducted to evaluate the importance of each input variable on the outcomes.</p
Covid-19 diagnosis and clinical symptom expression levels in a deep learning model
No full textIn December 2019, a new strain of virus called COVID-19 (previously designated as 2019-nCoV) caused the first detected outbreak in Wuhan City, Hubei Province, China and since then spread globally. Viruses can cause several types of damage to the respiratory tract, including Tracheitis; Bronchitis; Pneumonia. It is difficult to distinguish coronavirus pneumonia from some other microbiological causes through X-ray images. However, it can be distinguished from a normal person by chest X-ray and CT-Scan, along with clinical judgment through actual symptoms. The following article provides the process and setup of an analytical machine learning model and provides some clinical comparisons between the effectiveness of the machine learning model and the level of clinical symptomatology of a statistical sample. Medical records of some patients in Ho Chi Minh City, Vietnam
