Financial Development in Vietnam: An Overview
BUI, Toan Ngoc Korea Distribution Science Association 2020 The Journal of Asian Finance, Economics and Busine Vol.7 No.9
In this paper, we provide an overview of financial development in Vietnam. Particularly, a new approach of this study is to measure financial development through improvements in depth, efficiency and access of the banking system and stock market. Further, the study examines the factors significantly affecting financial development in Vietnam. The data are collected in Vietnam, an emerging country with a limited financial development. We employ the Autoregressive Distributed Lag (ARDL) approach, which generates a high reliability and suits data characteristics of emerging countries like Vietnam. We observe that Vietnam's banking system plays a key role in supplying credits to the economy while the nascent stock market at a limited size shows its potential for a considerable growth in the future. We also find the influential determinants of financial development in Vietnam including real estate market (RE), economic growth (EG), consumer price index (CPI), and global financial crisis (GFC). These findings are essential for Vietnamese authorities in providing practical solutions in order to build a sustainable and synchronous financial development. They are also first empirical evidence relating to an overview of financial development in an emerging country, so they are not only valuable to Vietnam but also crucial to other emerging economies.
A Study on Partitioning Freeform Surface and Tool Selection Method for 3-Axes CNC Machining
Bui Ngoc Tuyen,Hoang Van Quy,Duc-Toan Nguyen Korean Society for Precision Engineering 2019 한국정밀공학회지 Vol.36 No.9
Freeform surfaces are widely used in various industries. However, they require much time to be machined because of complicated geometry. To increase machining productivity, partitioning methods for freeform surface have been proposed by several previous studies regarding selection of cutting tools and tool-path. This paper proposes a new partitioning method based on Gaussian and mean curvatures to define boundaries of local patches using Freeman algorithm. Simulation results with a B-Spline surface show that the proposed method combined with cutting tool selection strategies can reduce machining time and surface roughness when compared with the non-partitioned method.

Relationships between Real Estate Markets and Economic Growth in Vietnam
My-Linh Thi Nguyen,Toan Ngoc Bui,Thang Quyet Nguyen 한국유통과학회 2019 The Journal of Asian Finance, Economics and Busine Vol.6 No.1
This study analyses the relationship between the real estate market and economic growth in Vietnam, a country with a fledgling real estate market. Research data included economic growth rate and growth rate of the real estate market in Vietnam. The research used quarterly data for the period from 2005: Q1 to 2018: Q1. With the characteristics of Vietnam, there has been no real estate index up to now; therefore, the research used data on growth rates of the real estate market. In addition, the real estate market in Vietnam is still young, so the data series is very short, which is a limitation of this research. With qualitative and quantitative methods especially with the Vector Auto Regressive (VAR) model; the results of the study indicate new findings, unlike previous studies, including: (1) The real estate market positively impacts Vietnam's economic growth, most noticeably in the second quarter lag and the fourth quarter lag, and then its trend impacts inversely; (2) The real estate market and economic growth in Vietnam have fluctuated over time with many risks that are affected by the past shocks of these factors. From these ndings, we proposed some managerial implications for managing the real estate market with economic growth in Vietnam sustainably.

This paper investigates the impact of the macroeconomy on Vietnam real estate market (REM). The research data were collected by the authors on a quarterly basis, from the third quarter of 2004 to the last counterpart of 2020. The authors utilize the Autoregressive Distributed Lag (ARDL) approach. The results reveal that REM is negatively influenced by the macroeconomy (interest rate and global crisis) in the short run and long run. This result is completely consistent with the wealth effect theory, the Austrian Business Cycle Theory (ABC), as well as the Arbitrage Pricing Theory (APT). However, the findings in this paper are valuable empirical evidence on the impact of the macroeconomy on REM in Vietnam, a developing country with relatively nascent REM. In particular, this study has achieved novelty compared to previous studies by finding the negative impact of the global crisis on REM, where the global crisis is defined to include the global financial crisis and the Coronavirus (COVID-19) pandemic crisis. Based on this, Vietnam needs to operate macroeconomic policies flexibly and in accordance with each period in order to develop REM in a stable and sustainable manner.

A series of N-substituted-1,2,3-triazole murrayafolineAderivativeswere successfully synthesized usingclick azide–alkyne Huisgen cycloaddition reaction between1-methoxy-3-methyl-9-(3-azido)-propyl-9H-carbazole andsubstituted alkynes. Their chemical structures were confirmedby 1H, 13C NMR and HR-ESI–MS spectral data. Inaddition, the interested effects on LPS-stimulated productionof pro-inflammatory cytokines in bone marrow-deriveddendritic cells of synthetic murrayafoline A derivatives werealso investigated. Our results indicated that murrayafoline Aderivatives containing 1,2,3-triazole nucleus potentiallypossessed anti-inflammatory action through inhibiting productionof IL-6, IL-12 p40 and TNF-a.
Fintech and Banking: Evidence from Vietnam
LIEN, Nguyen Thi Kim,DOAN, Thu-Trang Thi,BUI, Toan Ngoc Korea Distribution Science Association 2020 The Journal of Asian Finance, Economics and Busine Vol.7 No.9
The paper focuses on understanding fintech and the application of fintech in the banking sector in Vietnam. To solve this research objective, the authors analyze fintech development trends, especially the fintech application in the banking sector in Vietnam. To improve the quality of fintech services at banks, the authors conducted consideration of factors affecting customers' intention to use fintech services. To accomplish this, the authors collected data through a survey of 620 customers of the banks located in Ho Chi Minh City - the largest economic center in Vietnam. For the analytical method, the authors used multivariate regression to estimate the research model. Research results show that fintech service is very important for the banking sector in Vietnam. Moreover, this paper has achieved great success by identifying the factors that influence customers' intention to use fintech services. Accordingly, the intention to use fintech (INT) services is positively affected by the perception of usefulness (PU), social impact (SI), customer trust (TRU), and perceived ease of use (PEU). Based on the results of this study, bank managers will have a basis to improve the quality of fintech services. Not only that, the results of this study are also valuable for policymakers and researchers.
