The Effectiveness of Financial Sources for Climate Change in Vietnam
Thi Nhung NGUYEN(Thi Nhung NGUYEN ),Minh Hoa NGUYEN(Minh Hoa NGUYEN ),Thi Phuong Anh VU(Thi Phuong Anh VU ),Thi Hoang Anh DO(Thi Hoang Anh DO ) 한국유통과학회 2023 The Journal of Asian Finance, Economics and Busine Vol.10 No.1
This research aims to give information about the current situation of five financial sources for climate change in Vietnam, including (i) the State budget used by ministries; (ii) the State budget used by provinces; (iii) Bilateral funds; (iv) Multilateral funds; and (v) Private funds, and then classify them in line with the effectiveness. The working paper’s secondary data on spending on CC-related activities, collected from reports of six ministries and 29 provinces, show that the State budget has been crucial in subsidizing CC-related activities in Vietnam. Moreover, domestic investment has accounted for a major part of the total expenditure of ministries and provinces for climate change. In addition, by using primary data collected from surveys sent to twelve experts from 5 groups, such as researchers, practical experts, managers of private funding organizations (such as banks and enterprises), managers of international funding organizations and beneficiaries, and then analyzing the data through the AHP method, the study shows that all climate finance sources in Vietnam are still not very effective. However, private sector funds are considered the most effective financial source for responding to climate change.

This paper aims to develop a conceptual framework for evaluating the impact of motivational factors on the work results of lecturers at Vietnam National University, Hanoi (VNU), one of two leading multidisciplinary and multi-sectoral national universities in Vietnam. This study has considered wages and other benefits (WB), training and development (TD), working environment (WE) and working motivation (WM) as motivational factors, and proposed a structural model of the impact of motivational factors on the work results of lecturers at VNU. The empirical analysis used data from the survey data of 321 university lecturers. Comprehensive, valid, and reliable tools (SPSS 26 and SmartPLS 3.0 software) are used to evaluate rigorous statistical tests including convergence validity, discriminatory validity, reliability, and average variance extracted to analyze and verify the gathered data, and the hypotheses developed. The result of path analysis shows that four motivational factors constitute a structured system with different degrees of influence on the work results of lecturers. There is also a positive relationship between the motivational factors and the work results of lecturers. As a result, it can be concluded that all hypotheses developed are supported. Several recommendations are further suggested to improve the performance of lecturers at VNU.

Homogeneous Disturbance Observer Based on Sliding Mode Observer and Controller for T-Type Inverter
Do Tuan Anh,Pham Quoc Huy,Giap Van Nam,Nguyen Quang Dich,Vu Phuong 대한전기학회 2024 Journal of Electrical Engineering & Technology Vol.19 No.3
This paper proposes a novel sliding mode control (SMC) for the T-Type inverter in the standalone mode. Firstly, the accuracy of the estimated states used to construct the fxed-time SMC and the disturbance observer (DOB) is improved by a proposed sliding mode observer (SMO). Secondly, a DOB is designed without the requirement of the frst derivative or the format of the disturbance. Thirdly, an advanced reaching law is utilized for both the SMO, the DOB, and the SMC controller for the chattering elimination. Fourth, the stability of the proposed controller is confrmed by the Lyapunov condition. The performance of the proposed control strategy is validated by simulations and experiments with the same scenarios of nonlinear load and parameter variations. The results prove that the output voltage of the proposed control method meets the standard EN 62040 with the total harmonic distortion being lower than 5% in all cases, which is superior to the performance of the traditional controller.

Recently, vegetarian diets have experienced a dramatic increase in popularity. The aim of the study is to explore and test the relationship between the factors influencing consumers' dietary decisions in Ho Chi Minh City, Vietnam. The questionnaire applied a five-point Likert scale to investigate factors that affect Ho Chi Minh City's citizens when they have a vegetarian diet. 497 respondents (68% female; 61.2% aged 18-22; 82.7% had regular vegetarian diets) living in Ho Chi Minh City took part in both online and offline surveys. The results were processed by SPSS 22.0 software. The reliability was checked by Cronbach Alpha and Exploratory factor analysis (EFA) to identify the underlying relationships between measured variables. The Correlation analysis was implemented to show how strong and degree of two variables are related to each other before the multivariate regression equation was analyzed. The result showed the Five factors that were motivating people in Ho Chi Minh City to decide on plant-based diets, such as Animal Welfare, Health, Religion, Mood, and Reference groups. The mood is the most influential variable that significantly influences people's food choices. Attitudes toward vegetarian diets are changing. Therefore, recognizing the trends in food consumption might help companies take advantage of investment opportunities and build their marketing strategies.

Determinants Influencing Management Competency of Small and Medium Enterprise Directors in Vietnam
Thi Mai Huong DOAN,Minh Thuy DO,Thanh Lan MAI,Vu Phuong Anh DO,Thi Loan NGUYEN 한국유통과학회 2021 The Journal of Asian Finance, Economics and Busine Vol.8 No.12
Currently, small and medium-sized enterprises (SMEs) are accounting for about 98% of the total number of enterprises in Vietnam. Each year, SMEs create over one million new jobs, utilize up to 51% of the labor force in the society, and contribute more than 40% of GDP to the country. The study aims to analyze factors affecting the management competency of directors in small and medium enterprises in Vietnam. To achieve these research objectives, quantitative and qualitative methods were used concurrently. 300 questionnaires were sent out, but only 276 were collected and used for the quantitative analysis through SPSS 20.0 software. Cronbach’s Alpha, EFA, and regression were used to further confirm the research findings. The research findings show that all four proposed factors have impacts on the management competency of SME directors, among which enterprise features and specific policies for entrepreneur development in the locality have the strongest impacts, followed by personal features and business environment. The findings of this study suggest that managers need to focus on factors affecting the management competency of directors. This paper also provides new insight into the management competency of directors. Based on the findings, some recommendations are given for SMEs to improve management competency.
