Trinh,Pham T. T(Trinh,Pham T. T ),Nhan,Le P. A.(Nhan,Le P. A. ) People&Global Business Association 2023 Global Business and Finance Review Vol.28 No.4

Purpose: This study investigates the comovements of inflation across ASEAN countries and identifies the global factors driving the common inflation dynamics of the region. Design/methodology/approach: The study uses a two-step approach. The dynamic latent factor model is first employed to estimate the common inflation of the region in the period between 2000Q1 and 2022Q2. In the second step, a bound test approach to autoregressive distributed lag (ARDL) methodology is employed to estimate the model of common inflation, which is constructed based on the aggregate supply - aggregate demand (AS-AD) framework. Findings: The study finds a common factor of inflation across ASEAN countries. The analysis of variance decomposition indicates the significant role of common inflation in the variations of individual countries' inflation. World economic growth, oil price change, non-fuel commodity price change, and trade openness are the main drivers of ASEAN common inflation in both short and long terms. Research limitations/implications: The study focuses mainly on supply-side factors, although some demand-side factors are involved. Future studies should pay more concerns on the trade linkages among regional countries and the similarities in goals in the region. Originality/value: The study examines the common inflation component across ASEAN countries, which has not been sufficiently investigated. It also evaluates the drivers at the global level of common inflation, which has limited empirical evidence.

Purpose: Research on banking sustainability plays an important role in helping banks understand the level of risk in different types of companies. Therefore, this study was conducted to determine the factors affecting the sustainability of Joint Stock Commercial Banks in Vietnam. Research design, data and methodology: The following theories, the factors affecting the bank's sustainability include: Business model diversification (income diversification), bank size, loan ratio, and net interest margin. Data was collected from Joint Stock Commercial banks in Vietnam from 2015 to 2019. With GLS model on panel data with banks listed on Vietnam stock exchange. Results: The analysis results show that net interest income has a positive impact on the sustainable business results of banks through the rate of return on total assets (ROA). The non-interest income hasn’t impact on bank stability. From this result, there aren’t positive signs of income diversification in banks. At the same time, with the obtained results, the study also provides a policy implication for banks. Conclusions: The study also provides some policy implications to improve the bank stability. Diversifying income in banks is necessary, but how to make it influential banks has not yet been done. Therefore, the adjustments in non-interest business activities need to be carefully considered by banks.

On the properties of positive Boolean dependencies by groups in the database model of block form

Trinh Ngoc Truc,Trinh Dinh Thang,Tran Minh Tuyen 한국전산응용수학회 2022 Journal of applied mathematics & informatics Vol.40 No.3

The article proposed a new type of data relationship: Positive Boolean dependencies by groups on block and slice in the database model of block form, where instead of considering value pairs, we consider a group of p values ({p \geq 2}). From this new concept, the article stated and demonstrated the equivalence of the three types of deduction, namely: deduction by logic, deduction by block with groups, deduction by block has no more than p elements with groups. Operations on blocks or slices performed for index attributes on blocks, the properties related to this new concept as theorem the equivalen of the three types of deduction, closure of set positive Boolean dependencies by groups and representation and tight representation set of positive Boolean dependencies by groups when the block degenerated into relation are true in the relational database model and also stated and proven in this paper.

<P><B>Abstract</B></P> <P>This study presents a slidable paper-embedded plastic microdevice fully integrated with DNA extraction, loop-mediated isothermal amplification (LAMP), and colorimetric detection functionalities. The developed microdevice consists of three layers that allow a sliding movement to mix the sample and reagents for DNA purification, amplification, and detection in a sequential manner. An FTA card was employed in the main chamber for DNA extraction and purification from intact bacterial cells. Subsequently, LAMP reagents and fuchsin-stored chambers were pulled toward the main chambers for DNA amplifications at 65 °C. After 30 min, the detection reagents-stored chambers were then moved to main chambers for result analysis. For the detection of LAMP amplicons, a novel colorimetric fuchsin-based method was employed. The wide applicability of the integrated microdevice was demonstrated by successfully screening three major foodborne pathogens, namely <I>Salmonella</I> spp., <I>Staphylococcus aureus</I>, and <I>Escherichia coli</I> O157:H7 in food, enabling highly sensitive detection of 3.0 × 10<SUP>1</SUP> CFU/sample of Gram-negative bacteria (<I>Salmonella</I> spp. and <I>Escherichia coli</I> O157:H7) and 3.0 × 10<SUP>2</SUP> CFU/sample of Gram-positive bacteria (<I>Staphylococcus aureus</I>) within 75 min.

The development of the ethnic minorities and mountainous areas (EMMA) is currently receiving the attention of countries around the world. This is demonstrated through a large number of studies, in many respects, in many different countries. The objective of the study is to find out the current situation of the commodity market in the ethnic minorities and mountainous areas (EMMA) of Vietnam. In particular, the authors will study whether there is a link between the ability to access governmental policies and the characteristics of this commodity market. To achieve the goal, the authors employed the secondary data collection method to gather the relevant information on government policies for EMMA and conducted an interview of seventy (70) enterprises in the Northern midlands and mountainous regions and the Central Coast to clarify the characteristics of commodity market. By Levene’s test, the results showed that the accessibility to governmental policies has a certain influence on the development of the commodity market patterns in the EMMA in terms of diversification of distribution forms and sales method of the business. These findings brought some basic solutions to further enhance the role of the government in developing commodity markets in the EMMA of Vietnam.

Waveguide Slot Array Antenna with a Hybrid-Phase Feed for Grating Lobe Reduction

Trinh-Van, Son,Song, Sung Chan,Seo, Seung-Hee,Hwang, Keum Cheol Hindawi Limited 2016 International journal of antennas and propagation Vol.2016 No.-

<P>The design of a 112-element millimeter-wave waveguide slot array antenna to reduce the grating lobe level is presented. A hybrid-phase feeding technique combining a cophase feed and an alternating-phase feed is applied to facilitate the suppression of grating lobes. In addition, a stepped feed waveguide and offset coupling slots aligned in a line are employed to realize a tapered aperture distribution. As a result, grating lobe suppression of 8.1 dB was achieved on the diagonal planes compared to a conventional alternating-phase-fed waveguide slot array antenna. A prototype of the proposed antenna was fabricated and measured. The measured results show that the proposed antenna exhibits a −15 dB reflection bandwidth of 3.4%and an average realized gain of 26.72 dBi within the measured frequency range. Good agreement between the simulated and measured radiation patterns is also observed.</P>

Nonlinear thermomechanical behaviors of thin functionally graded sandwich shells with double curvature

Trinh, Minh-Chien,Kim, Seung-Eock Elsevier 2018 Composite structures Vol.195 No.-

<P><B>Abstract</B></P> <P>Analytical closed-form solutions for thermos-mechanical stability and explicit expressions for free- and forced- vibration of thin functionally graded sandwich shells with double curvature resting on elastic bases are investigated for the first time in this study. A core layer of ceramic and two cover layers of functionally graded materials constitute the shell structure. Governing equations are derived from the classical shell theory using Hamilton’s principle admitting Volmir assumption and von Karman nonlinear displacement fields. Theoretical solutions are achieved by using the Bubnov-Galerkin procedure in solving differential equations. Parametric studies showing the effects of temperature-dependent features, material constituents, initial geometry imperfections, external thermos-mechanical loadings, elastic bases, and geometry configuration on static and dynamic behaviors of the shells are performed. Thin functionally graded sandwich spherical, cylindrical, and hyperbolic paraboloid shells are studied. Snap-through phenomena under load-control conditions are recognized in thin functionally graded sandwich cylindrical shells. The fourth-order Runge-Kutta method is employed to numerically solve dynamic problems and four analogies are drawn to validate theoretical formulations.</P>

Safe driving is one of important factors for evaluating the traffic service quality. Almost traffic accident were caused by human errors, which was about 94% according to the National Highway Traffic Safety Administration (Singh, 2015). In order to solve the safe driving problem, autonomous vehicles (AVs) were getting a promising way to reduce accidents, human stress, and emissions (Crayton and Meier, 2017). Moreover, the development of cooperative intelligent transport systems (C_ITS) and advanced driver assistance systems (ADAS) can help to push the AVs in the real environment. Various studies mainly focused on an operation of AVs under mixed traffic environment in which the AVs will share the road with human-driven vehicles. Recently, reinforcement learning (RL) is a branch of machine learning, which optimized the reward to generate an appropriate policy for autonomous agents. The Markov decision process (MDP) is an original RL for full observations. In order to address the uncertain environment, the partially observable Markov decision process (POMDP) was applied for the partial observation MDP, such as traffic signal control (Manniona et al., 2015) and roundabout(Garc Cuenca et al., 2019).

Trinh, Hien-Trung,Bae, Eun-Ah,Han, Myung-Joo,Shin, Yong-Wook,Kim, Dong-Hyun The Korean Society of Ginseng 2007 Journal of Ginseng Research Vol.31 No.3

To evaluate the antiatopic effect of Korea Red Ginseng (RG, steamed root of Panax ginseng C.A. Meyer, Family Araliaceae), its inhibitory effect on passive cutaneous anaphylaxis reaction and itching in mice was measured. RG and its ingredient saponin fraction (SF) potently inhibited passive cutaneous anaphylaxis (PCA) reaction and scratching behaviors. RG at a dose of 100 mg/kg and SF at a dose of 50 mg/kg significantly inhibited the scratching frequency by 32% and 38%, respectively. RG and SF also inhibited the degranulation and protein expression of tumor necrosis factor $(TNF)-{\alpha}$ and interleukin (IL)-4 of RBL-2H3 cells induced by IgE-antign complex. However, polysaccharide fraction of RG did not inhibit it. Based on these findings, RG can improve allergic skin disorders atopic dermatitis and contact dermatitis by the regulation of $TNF-{\alpha}$, and IL-4 produced by mast cells and basophils and their membrane stabilization.
