Key Attributes of Banking Website Quality in Vietnam: A Decision Tree Approach
Pham,Thi Thanh Xuan,Nguyen,Tien Nhat 한국유통과학회 2019 KODISA ICBE (International Conference on Business Vol.2019 No.-
This study aims to explore key factors of commercial bank’s website quality impacting on the process of making decision to use internet banking services. It was conducted as a case study of four big commercial banks of Vietnam, namely Vietinbank, Vietcombank, BIDV and Sacombank that have many online services and retails agencies nationwide. Data was collected by surveying customers of these banks, then the decision tree model was applied to analyze it with using Weka software. According to a result of the decision tree, there are four essential attributes of the website quality: Information quality, Visual appearance, Accessibility, and Interactivity. No previous study has investigated this subject in Vietnamese banking system, so the findings should make an important contribution to this field.

This study seeks to examine the relationship between business resources (through VRIN: Valuable - valuable, Rare - scarce; Inimitable - difficult to adapt, Irreplaceable - hard to replace), dynamic capability, external cooperation, and efficiency of startups operating in the seafood export sector. Research data was collected randomly and conveniently from 250 enterprises in Ba Ria-Vung Tau province, Vietnam, from October 2020 to December 2020. After excluding those ineligible, the remaining 204 enterprises meet the research conditions. With the support of SPSS-AMOS 22 dedicated software, using the 5-step Likert scale and Structural Equation Modeling (SEM), the study conducted analysis steps such as verifying convergence, discriminant value, unidirectional and scale reliability when giving the components correlated freely in the critical model by Confirmatory Factor Analysis (CFA) analysis. Results of the study have shown that the enterprise resource factor - VRIN has a positive impact on dynamic capability, and outside cooperation. However, in contrast to previous studies, we found that the relationship between enterprise resources - VRIN and performance as well as the relationship between dynamics capacity and performance is not clear. This shows that seafood exporters need to promote, exploit and effectively use this precious resource to improve business efficiency.

Purpose: Research on attracting foreign direct investment plays an important role in ASEAN countries. ASEAN has needed FDI capital for development and integration with many developing countries. Research design, data and methodology: This study is conducted to assess the impact of factors: inflation (INF), economic growth (GDP), population (POP), and trade (TRADE) on attracting foreign direct investment (FDI) of ASEAN countries. The study will find out how factors distribution contributes to FDI attraction. The study collects data from 10 ASEAN countries from 2010 to 2020. With data collected for ten countries from 2010 to 2020, data analysis with panel data will be used in this study. The Regression with Driscoll-Kraay standard errors correction model will be used in the study. Results: Panel data analysis shows that economic growth and population positively impact FDI attraction in ASEAN countries. However, two factors: INF and TRADE, do not affect FDI. Conclusions: Countries need to focus on economic development, create many good conditions for people and domestic enterprises and create opportunities for foreign investors to pay more attention. improving the quality of domestic human resources will help to better improve the working quality factor when the demand for high-quality human resources increases.

Nanocomposites containing two or more functional constituents are attractive candidates for advanced nanomaterials. In this study, multifunctional Ag/Fe3O4-CS nanocomposites were successfully prepared, using chitosan as a stabilizing and cross-linking agent. The as-synthesized nanocomposites were characterized by Transmission Electron Microscopy (TEM), Scanning Electron Microscopy (SEM), X-ray diffraction (XRD), Energy-dispersive X-ray spectroscopy (EDS), UVevisible spectrophotometer (UVeVis) and vibrating sample magnetometer (VSM). The results demonstrated that Ag/Fe3O4-CS composite nanoparticles (NPs) were composed of parent components, Fe3O4 and Ag NPs, which were uniformly dispersed in the chitosan matrix. The hybrid NPs exhibited strong antibacterial property against Pseudomonas aeruginosa. With high magnetization value (67 emu/g), the synthesized Ag/Fe3O4-CS composite can be easily separated or recycled in potential biomedical applications. Furthermore, the results showed that the multicomponent hybrid nanostructures appeared to be the promising material for local hyperthermia, which can be used as thermoseeds for localized hyperthermia treatment of cancers.

A total of six markers RM3586 and RM160 on chromosome 3 and RM3735, RM3471, RM3687 and RM3536 on chromosome 4 were used to select promising lines in backcrossing populations for heat tolerance at flowering stage in rice. Fifty lines selected in BC3F2, BC4F1, and BC4F2 and parents were planted in 2013, and 2014 dry seasons at the CLRRI field under natural heat stress and greenhouse to evaluate heat tolerance at the reproductive period. Heat tolerance scoring under field condition was based on percentage of unfilled grains. All selected lines exhibited their homozygous alleles with two heat tolerance germplasm N22 or Dular in QTL loci. Twelve lines harboring homozygous alleles to QTL loci RM3586 on chromosome 3 and RM3735 on chromosome 4, respectively were selected and evaluated to agronomic traits and yield potential. Four lines BC4-1-10-1 from OM5930/N22//4 *OM5930, BC4-5-8 from OM5930/Dular//4*OM5930, BC4-5-9-4 from AS996/N22//4*AS996, and BC4-6-3 from AS996/Dular//4 *AS996, respectively were finally selected to would be for regional adaptable test in Central Coast of Vietnam under heat stress condition to release to rice farmers.
Impact of Service Quality, Customer Satisfaction and Switching Costs on Customer Loyalty
NGUYEN, Do Thanh,PHAM, Van Thanh,TRAN, Dung Manh,PHAM, Duyen Bich T. Korea Distribution Science Association 2020 The Journal of Asian Finance, Economics and Busine Vol.7 No.8
This study examines the relationships and the impacts of service quality, customer satisfaction and switching costs on customer loyalty of e-banking in commercial banks. This study uses questionnaires with 7-point Likert scale to collect data from 227 e-banking users, who are mainly students and paid employees in Hanoi City, Vietnam. The collected data are analyzed by using multivariate linear regression method. The results show that all five factors of service quality in e-banking - reliability, responsiveness, service capacity, empathy and tangibility - have positive correlations with customer satisfaction. Among these determinants, service capacity and tangibility have the strongest impact. It means that, by increasing the quality of their services through five above factors, especially through improving capacity and tangibility, commercial banks can satisfy their customer better. In addition, customer satisfaction is strongly and positively correlated to customer loyalty. It means that, if customers are satisfied with e-banking services of one bank, they not only continue to do more businesses with this bank, but also recommend this bank to other people. Lastly, customer loyalty also has a strong and positive correlation with switching costs, which means customers tend to be loyal to one bank if the barriers to switching banks increase.
