Fintech Credit - Opportunities for SMEs in Vietnam
Truong,Van Khanh,Tram,Bich Loc 한국유통과학회 2019 KODISA ICBE (International Conference on Business Vol.2019 No.-
Small and medium enterprises (SMEs) have an important role in the development of countries, especially in developing ones like Vietnam, but access to capital of this type of business is always difficult, while the support of the Vietnamese government has not been effective or negligible. However, the fourth industrial revolution (industry 4.0) have created a new type of business - Fintech companies which provide SMEs an easier way to access capital. Nevertheless, the concept of Fintech is relatively new in Vietnam and the operation of these companies implicit certain risks. Therefore, in order to help SMEs take advantage of this non-bank capital resource, the authorities are asked to promulgate laws or decrees for business environment of Fintech companies.
Unsolved Problem in Human Resources Qualities of Vietnamese Banking Industry in Integration
Truong,Van Khanh,Tram,Bich Loc 한국유통과학회 2019 KODISA ICBE (International Conference on Business Vol.2019 No.-
Economic integration become the inevitable trend of all countries around the world brings not only opportunities but also challenges for all aspects of society, especially the banking sector. Meanwhile, workforce in Vietnamese banking sector has been not only insufficient but also leftovers, which creates unsolvable problems for unemployment in the current period and for the competitiveness of the sector in near future. After conducting research in many different aspects, this paper finds out the main reasons why banker resources have not met the requirements of society, which can be summarized as follows: management methods of State agencies have only been implemented for form’s sake and their development planning is not appropriate for economic environment; most of training facilities focus on scale rather than the quality; the way of doing business of some banks creates a lot of potential risk but they have no appropriate management mechanism; and students majoring in banking sector have negligent learning attitude and deviant thinking of their career in future.
A Study on Parallel Force/Position Control Applied to Hybrid Electro-Hydrostatic Actuators
Dinh Quang Truong1,Ahn Kyoung Kwan 제어로봇시스템학회 2009 제어로봇시스템학회 국제학술대회 논문집 Vol.2009 No.8
Hydraulic power systems and actuators play an important role in modern industry. In order to improve the control performance of electro-hydrostatic actuator (EHA), the aim of this paper is to propose a novel parallel control strategy named parallel self tuning Quantitative Feedback Theory (PSTQFT) to apply to control force and position of a new kind of hydraulic experimental system named electro-hydrostatic load simulator (EHLS). The PSTQFT controller is designed based on QFT technique for both the force and position control of the EHLS. Then the parameters of the PSTQFT force and position controller are automatically tuned online to minimize the system error by using gradient descent method and speed up convergence. Experiments are carried out to evaluate the effectiveness of the proposed parallel force and position control method applied to the EHLS system.

In general, using information and communication technology (ICT) to support problem-solving is becoming increasingly common across various industries, sectors, and regions. However, there have been few analyses on the factors affecting ICT problem-solving among officers working at People’s Committees of mountainous communes. Using survey data, exploratory factor analysis (EFA), and multivariable linear regression, this study examined the factors that influence the use of ICT in resolving works among community officers at People’s Committees in the Northwest mountainous region of Vietnam. The results showed that three factors with statistical significance affecting the dependent variable are computer skills, gender, and occupation of community officers. Therefore, it is recommended that officers participate in ICT training courses or engage in regular self-study to improve their computer skills and qualifications. Both men and women should also prioritize the use of ICT equipment. The study also found that officers in managerial positions were more likely to use ICT for problem-solving than their counterparts. However, some factors that affect the use of ICT were not identified in this study, leaving room for further research.
Determination of k0 factors of short-lived nuclides 46mSc and 110Ag for the k0-NAA
Truong Truong Son,Ho Van Doanh,Ho Manh Dung 한국원자력학회 2023 Nuclear Engineering and Technology Vol.55 No.9
The k0-standardization neutron activation analysis method has successfully determined the mass fraction of elements of interest using around a hundred analytical radionuclides. However, several very short-lived nuclides with half-life less than 100 s have not been used at Dalat research reactor. One of the reasons is that the values of k0-factors of these nuclides are significantly different. Therefore, this work focused on re-determination and evaluation of k0-factors of very short-lived nuclides 110Ag (T1/2 ¼ 24 s) and 46mSc (T1/2 ¼ 18.75 s). The results of determination of the short-lived nuclides revealed that k0-factor of 110Ag is significantly difference between the existing data and the obtained results in this work. The evaluation of the k0-factors was done by using the obtained results for application of k0-NAA for NIST1566b and NIST-2711A standard reference materials

Purpose: This paper (1) identifies the factors that affect people's changing habits towards waste sorting, (2) evaluates the benefits of waste sorting to the environment and (3) designs communication strategies to change people's behavior and habits in sorting plastic waste in Ho Chi Mnh City, Vietnam. Research design, data and methodology: Using the data from 309 people that are living in Ho Chi Minh City and Structural Equation Modeling (SEM), to evaluate variables and test the hypotheses. Results: Research results show that attitudes, subjective standards, behavioral control, and facilities affect people's intention to classify plastic waste. We find that environmental concerns greatly influence people's attitudes. In contrast, environmental concerns have a relatively weaker effect on people's degree of behavioral control. Conclusion: Environmental protection is a matter of concern in the world. In Vietnam, this issue has been institutionalized into law to create a basis for improving the effectiveness of environmental protection activities. This article has some limitations. Firstly, sample is limited to HCMC residents; the study results are not representative of the entire population of Vietnam. This paper is based on cross-sectional data, which is not the best way to establish a causal relationship between the intention to sort plastic waste and its drivers.

Truong, Dinh Quang,Truong, Bui Ngoc Minh,Ahn, Kyoung Kwan,Lee, Jae Shin Korean Society for Precision Engineering 2015 International Journal of Precision Engineering and Vol.16 No.9
Lubrication is one of the most important factors in developing internal combustion engines. And vane pumps are known as potential choices for conducting the engine lubrication systems. To better optimize the lubrication performance, an electronically controlled variable displacement vane pump developed from a typical vane pump is newly introduced in this paper. Firstly, the concept and methodology to design properly an electric actuator to provide an additionally degree of pump control by regulating the pump displacement is carefully considered. Secondly, a control logic is developed to manage the operation of the actuator and subsequently, smoothly varying the pump output in order to satisfy any given lubrication profile. Finally, test rigs are setup to investigate the performances of the fabricated actuator and pump prototype. Practical tests are performed to evaluate the effectiveness of the newly pump design over the typical one.

In this paper, a novel magnetic actuator named Linear Magnetic Actuator (LMA) is proposed, designed and fabricated for applications such as active magnetic bearing systems to deal with vibration problems in rotating machines. The LMA actuator is constructed from a moving body called 'mover' and three driving parts which drive the mover. Real-time experiments on the LMA have been conducted to derive a mathematical model for this actuator to investigate the generated electro-magnetic force as well as further research. The modeling results in a comparison with the actual performance show that the electro-magnetic force varied symmetrically with the mover motion defined by the applied current. Furthermore, an advanced trajectory controller - online tuning fuzzy PID controller has been designed for the LMA in order to improve the working performance. Finally, real-time experiments have been carried out to investigate the tracking performance of the designed LMA control system. The experimental results prove that the LMA driven by the proposed controller could track the desired trajectories with high accuracy.
Numerical investigations of solidification around a circular cylinder under forced convection
Truong V. Vu,Anh V. Truong,Ngoc T. B. Hoang,Duong K. Tran 대한기계학회 2016 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.30 No.11
We present numerical investigations of solidification around a cooled circular cylinder in the presence of forced convection. The numerical method is based on the front-tracking/finite difference and interpolation techniques. The solidification interface is represented by connected elements that move on a fixed, rectangular grid. The no-slip and Dirichlet temperature boundary conditions are imposed by the linear interpolation. The interpolation method was first validated through comparisons of the present results with some other numerical results for flow in an annulus, flow in an enclose with a conduction solid body and flow over a heated cylinder. We then used the method to investigate the solidification process around a cold cylinder by varying various parameters such as the Reynolds number Re, the Prandtl number Pr, the Stefan number, the thermal conductivity ratio k sl , the non-dimensional temperature of the introduced liquid q 0 , and the solid-to-liquid density ratio r sl . Numerical results indicate that an increase in any of Re, Pr and q 0 results in a decrease in the area of the solidification region around the cylinder. In contrast, increasing k sl increases the region of the solid phase. Investigation on St and r slreveals that the solidification rate increases with an increase in St or a decrease in r sl . However, St and r sl have a minor effect on the final product of the solidification process.
