Tourist Motivation as an Antecedent of Destination and Ecotourism Loyalty

Objective: This study evaluates the role of tourist motivation in the determination of destination and ecotourism loyalty using push and pull motivation theory and the theory of planned behavior. The paper also analyses the mediating effects of satisfaction and destination image in the relationships between motivation and the two types of loyalty. Method/analysis: Primary data has been gathered from surveys involving 522 Vietnamese tourists traveling to the Bohemian Switzerland National Park in the Czech Republic. Data analysis was conducted using structural equation modeling (SEM) techniques in R. Findings: The findings support both direct and indirect positive associations between tourist motivation and destination and ecotourism loyalty. In terms of ecotourism loyalty, the effect is mediated by destination image. In terms of destination loyalty, the effect is mediated by satisfaction and destination image. Novelty/improvement: This study has further expanded the theory of planned behavior in the context of ecotourism by linking it to travel career pattern theory and functionalist theory. These are complementary theories that can explain the behavior of ecotourists and help operators and marketers adjust their strategies to attract and retain visitors to ecotourist destinations. Doi: 10.28991/ESJ-2022-06-05-014 Full Text: PD

A Hybrid Photorealistic Architecture Based on Generating Facial Features and Body Reshaping for Virtual Try-on Applications

Online shopping using virtual try-on technology is becoming popular and widely used for digital transformation because of sustainably sourced materials and enhancing customers’ experience. For practical applicability, the process is required for two main factors: (1) accuracy and reliability, and (2) the processing time. To meet the above requirements, we propose a state-of-the-art technique for generating a user’s visualization of model costumes using only a single user portrait and basic anthropometrics. To start, this research would summarize different methods of most virtual try-on clothes approaches, including (1) Interactive simulation between the 3D models, and (2) 2D Photorealistic Generation. In spite of successfully creating the visualization and feasibility, these approaches have to face issues of their efficiency and performance. Furthermore, the complexity of input requirements and the users’ experiments are leading to difficulties in practical application and future scalability. In this regard, our study combines (1) a head-swapping technique using a face alignment model for determining, segmenting, and swapping heads with only a pair of a source and a target image as inputs (2) a photorealistic body reshape pipeline for direct resizing user visualization, and (3) an adaptive skin color models for changing user’s skin, which ensures remaining the face structure and natural. The proposed technique was evaluated quantitatively and qualitatively using three types of datasets which include: (1) VoxCeleb2, (2) Datasets from Viettel collection, and (3) Users Testing to demonstrate its feasibility and efficiency when used in real-world application

Impact of Fintech’s Development on Bank Performance: An Empirical Study from Vietnam

In recent years, fintech has exploded in popularity and importance in the finan- cial industry. Its impacts have spread widely throughout the world, including Vietnam. This study aims to investigate the effect of fintech’s development on bank performance in Vietnam. Based on the unstructured data about fintech on the financial expert web- sites from Vietnam, the word frequency statistic technique of the text mining approach is applied for measuring fintech’s development under the support of Python-based solu- tions. The bank-level data of 15 Vietnamese banks for the period from the first quarter of 2019 to the second quarter of 2021 are collected from the quarterly financial statements in the Vietstock organization. Python programming and text mining techniques are used to compile this dataset by gathering information from popular and relevant websites. The generalized least squares method is used for estimating the panel models. The estimation result shows the significant impact of fintech’s development on bank profitability, but the net interest margin does not associate with the fintech variable. Besides, some interesting findings are revealed: The slow banking transformation to adapt to the rise of fintech and the COVID-19 pandemic increased bank profitability. Furthermore, suggestions for the banks and fintech companies are recommended, and the limitations and directions for further research are also proposed

The Role of Multi-Sensory Experience Toward Perceived Medical Service Quality: A Research at Vietnam Public Hospital

The theory of Sensory Marketing has been developed as a special approach to help managers understand customers through creating multi-sensory experiences. In medical services, a patient's multi-sensory experience with a medical facility will shape each customer's different perception of service quality. The article evaluates the role of multi-sensory experience in customers’ perceived service quality at public hospitals in Vietnam. Research results have shown that tactile, olfactory, visual and taste stimuli have a significant influence on the perceived service quality of customers when experiencing medical services. Besides, the authors also detected that customer’s expectation and satisfaction have a proportional relationship. Discussions and recommendations on the application of sensory marketing to improve people's perception of the medical service quality have been proposed to enhance the brand image of Vietnam's public hospitals as well as to ensure the interests of the customer during the use of the service. Keywords: sensory marketing, perceived service quality, medical service, public hospital. DOI: 10.7176/JMCR/83-02 Publication date: December 31st 202

Covid-19 And Factors Affecting Vietnamese Students’ Readiness For Digital Transformation

Education in Vietnam is trying to make use of the values of the digital technology revolution. As one of the eight key fields of National Digital Transformation, education needs to find ways to develop and take advantage of opportunities to be able to shape the future of society with high-quality human resources. As a huge challenge, the Covid-19 pandemic has quickly put pressure on the past predicted trends in education such as the “university of the future”, but, from a positive viewpoint, it also brings a big opportunity for universities to make the transformation, from classic one to the new and trendy university – the digital one. The paper analyzes in-depth the factors affecting the readiness of Vietnamese students for digital transformation in the above context. The research model is built based on the Technology Acceptance Model (TAM) theory and corrects necessary variables. The results show that the impact of Covid-19, self-study ability and attitude are the factors that have the most influence on the willingness to shift the learning method towards digitization. According to the result, the authors will propose several recommendations on improving the readiness of Vietnamese students for the digital transformation of education and training. Thereby helping students change to adapt to learning activities when the pandemic appears, and know how to take advantage of digital transformation. Keywords: digital transformation, Covid-19, awareness, attitude, self-study DOI: 10.7176/JEP/12-16-04 Publication date:June 30th 202

Fuzzy gain scheduling control apply to an RC Hovercraft

The Fuzzy Gain Scheduling (FGS) methodology for tuning the Proportional – Integral – Derivative (PID) traditional controller parameters by scheduling controlled gains in different phases, is a simple and effective application both in industries and real-time complex models while assuring the high achievements over pass decades, is proposed in this article. The Fuzzy logic rules of the triangular membership functions are exploited on-line to verify the Gain Scheduling of the Proportional – Integral – Derivative controller gains in different stages because it can minimize the tracking control error and utilize the Integral of Time Absolute Error (ITAE) minima criterion of the controller design process. For that reason, the controller design could tune the system model in the whole operation time to display the efficiency in tracking error. It is then implemented in a novel Remote Controlled (RC) Hovercraft motion models to demonstrate better control performance in comparison with the PID conventional controller
