The Global Factors Driving Common Inflation In ASEAN
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.

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.

<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.

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.
Brexit and Asian Exports: A Value Chains Perspective
Trinh Quang Long 연세대학교 동서문제연구원 2020 Global economic review Vol.49 No.3
The UK departure from EU (Brexit) has profound economic implications for all countries engaged in the global value chains. Using a new decomposition approach, this study examines the position of Asian exports in the EU27-UK supply chains trade. We find that total Asian VA embedded in the EU27-UK supply chains trade increased during 2000–2014, mostly due to the emergence of China. Although Japan’s position in the EU27-UK supply chains trade declined, her positions in the supply chains trade between EU27 (the UK) and all EU27’s (the UK’s) trading partners have increased. Some Asian industries, including computer and electronic and electrical equipment or textile and garment apparel, may affect heavily due the EU27-UK trade disruptions.

In this study, mixed softwoods were pretreated with an ionic liquid, 1-butyl-3-methylimidazolium chloride ([Bmim]Cl), and the bioconversion efficiencies to fermentable sugars were estimated through the enzymatic hydrolysis. The cellulose crystallinity, surface morphology, structures and compositions of softwood were significantly changed after the ionic liquid pretreatment was carried out under a wide range of temperatures and reaction times. And, biomass digestibility significantly increased with increasing pretreatment temperature and reaction time. The enzymatic degradation of pretreated softwoods was remarkably improved at the pretreatment of high temperatures via the modification of crystalline cellulose I to a mixture of easily digestable cellulose II and amorphous structure, and partial removal of hemicellulose. The conversion of cellulose to glucose reached more than 90% at relevant conditions and the highest glucose yield was measured to about 78%. Through the study, it was clearly shown that ionic liquid pretreatment is one of the effective methods to produce high fermentable sugars without lignin dissolution from lignocellulosic biomass.
