Evaluating the Efficiency of Vietnamese Banking System: An Application Using Data Envelopment Analysis

Over the last twenty years in Vietnam, the financial system in general and the banking system in particular had been transferred from a monopoly system into a diversified system which allows all participants to compete fairly and effectively. Within these past years, the banking system in Vietnam did gradually developed in number of banking institutions, size of the banking sector in the economy, amount of credits for the economy, and amount of other banking services as well. Along with the development of the banking system in number, size, asset value, deposit, credit and debit account, ATM/POS, interest rates, etc. which attracted more and more customers using the banking’ services; the efficiency of the banking system also has been increasing. So far, there is still a lack of research on the efficiency of the banking sector in Vietnam over the decades. Several researches were conducted, however, due to the data limitation, these researches were just small steps at the big front gate. This paper, which focuses on evaluating the efficiency of bigger sample size of Vietnamese commercial banks in the year of 2008, tends to make a contribution to this progress. The DEA approach allows this paper to evaluate the efficiency of 22 Vietnamese commercial banks in using their inputs in 2008 (these banks were ranked top in the banking industry in Vietnam – VNR500 in 2009). After analyzing, the research comes to a conclusion that although the efficiency of these banks is averagely high, however, there is still an opportunity to improve this indicator.Data envelopment analysis, Vietnam, bank, efficiency

Impact of energy consumption and agriculture growth on the environmental degradation: evidence from ASEAN countries

Globally, renewable and nonrenewable energy usage have been identified as key indicators of environmental degradation, necessitating additional investigation. This essay aims to examine the impact of energy use and agricultural expansion on environmental degradation. The paper selected several energy consumptions factors, including renewable energy, fossil fuel, electric power, energy consumption, energy import, and GDP. The study gathered secondary data from World Bank indicators from 1991 to 2020 from ASEAN countries. Phillips-Perron (PP) and Augmented Dickey-Fuller (ADF) approaches were utilized to analyze unit roots between constructions. The study also considered the QARDL approach to assess the correlation between selected constructs. In the sample of ASEAN economies, renewable energy consumption and CO2 emissions were inversely linked; however, other variables demonstrated a positive relationship with CO2 emissions. After the paper, several ramifications were outlined that could aid regulators in taking corrective action regarding CO2 reduction through REC.Khoa Dang Duong (Vo Truong Toan University), Thanh Quang Ngo (School of Government, University of Economics Ho Chi Minh City (UEH))Includes bibliographical references

Assessment of High School Students’ Learning and Development of Qualities and Competencies: A Case Study

This study aims to assess high school students' learning outcomes, their achievement of goals and fulfilling academic requirements and how the entire teaching and learning process takes place. The study, consisting of an experimental group and a control group was conducted for pre-test and post-test comparisons of the academic performance of 88 10th grade students. 44 students were selected as the experimental group that underwent a specific teaching strategy to monitor their development of qualities and competencies in one semester, and the remaining 44 students acted as the control group. The data collected after the tests were analyzed using SPSS software (V20). The results showed that the students in the experimental group had better academic results than those in the control group. The findings of this study have implications for policy, further research as well as approaches for the assessment of students’ development of qualities and competencies in Vietnam

Organisational Baseline Study: Overview report for Tra Hat CSV, Vietnam (VN03)

This report covers the Organisational Baseline Study (OBS) for the CCAFS Climate-Smart Village Tra Hat in the South Viet Nam. During October 2014 interviews were conducted with local stakeholders at ten organisations who are working or collaborating with farmers and/or the community in Vinh Loi district, Bac Lieu province. The Tra Hat CSV is located near the coastal area, at tail end of a primary canal of Quan Lo Phung Hiep system (QLPH), the Mekong Delta of Vietnam, it usually causes lack of fresh water in from QLPH in dry season. There are two distinct dry season (December to April) and rainy season (May to November) which typhoon happens seldom in rainy season. Protected by dyke and sluice system of QLPH in Bac Lieu province, Tra Hat has not been affected by saline intrusion for last 15 years. The main farming systems in the village comprise two or three rice crops per year, small livestock as pig, chicken and ducks. Besides, mixed fruit garden and cash crop are often blended in residential area. Ground water and water in ponds is popular in household to provide domestic water, raising fish or garden irrigation and livestock, especially in dry season. The objectives of the OBS study are to: Provide indicators to monitor changes in behaviours and practices of locally relevant organisations that have climate change related activities in Bac Lieu over time Understand the provision of information/services at the local level that informs farmers’ decision making about their livelihood strategies in response to climate change This OBS report also supplements to the quantitative Household Baseline Survey (HBS) and the qualitative Village Baseline Studies (VBS) in Tra Hat CSV and surrounding villages

Jamming Signal Cancellation by Channel Inversion Power Control for Preserving Covert Communications, Journal of Telecommunications and Information Technology, 2023, nr 2

Uninformed jammers are used to facilitate covert communications between a transmitter and an intended receiver under the surveillance of a warden. In reality, the signals the uniformed jammer emits to make the warden’s decision uncertain have inadvertently interfered with the detection of the intended receiver. In this paper, we apply truncated channel inversion power control (TCIPC) to both the transmitter and the uninformed jammer. The TCIPC scheme used on the uninformed jammer may help the intended receiver remove jamming signals using the successive interference cancellation (SIC) technique. Under the assumption that the warden knows the channel coefficient between two intended transceivers and achieves the optimal detection power threshold, we form the optimization problem to maximize the effective transmission rate (ETR) under covertness and decoding constraints. With the aim of enhancing covertness-related performance, we achieve the optimal power control parameters and determine system parameter-related constraints required for the existence of these solutions. According to the simulations, the use of the TCIPC scheme on the uninformed jammer significantly improves covertness-related performance in comparison to that of random power control (RPC) and constant power control (CPC) schemes. In addition, simulation results show that, for the TCIPC scheme: 1) the maximum ETR tends to converge as the transmitter’s or the uninformed jammer’s maximum transmit power increases, and 2) there exists an optimal value of the transmitter’s predetermined transmission rate to achieve the optimal performance

An Approximate Evaluation of BER Performance for Downlink GSVD-NOMA with Joint Maximum-likelihood Detector, Journal of Telecommunications and Information Technology, 2022, nr 3

Generalized Singular Value Decomposition (GSVD) is the enabling linear precoding scheme for multiple-input multiple-output (MIMO) non-orthogonal multiple access (NOMA) systems. In this paper, we extend research concerning downlink MIMO-NOMA systems with GSVD to cover bit terror rate (BER) performance and to derive an approximate evaluation of the average BER performance. Specifically, we deploy, AT the base station, the well-known technique of joint-modulation to generate NOMAsymbols and joint maximum-likelihood (ML) to recover the transmitted data at end user locations. Consequently, the joint ML detector offers almost the same performance, In terms of average BER as ideal successive interference cancellation. Next, we also investigate BER performance of other precoding schemes, such as zero-forcing, block diagonalization, and simultaneous triangularization, comparing them with GSVD. Furthermore, BER performance is verified in different configurations in relation to the number of antennas. In cases where the number of transmit antennas is greater than twice the number of receive antennas, average BER performance is superior
