The impact of human capital on the economic growth of Vietnam’s cities and provinces: a spatial econometrics approach
Authors: Van Si Nguyen , Trung Kien Le
Published: April 2020

Human capital is crucial for national economic growth and for local economic growth as well. In an attempt to investigate the effect of human capital on the economic growth in Vietnam’s cities and provinces, the author adopts spatial econometric models of SDM, SAR, SEM for panel data. Human capital is measured by regular expenditure on education and numbers of trained labors in each province/city. The data used in this study is obtained from the Statistical Yearbook of 63 provinces published by the General Statistics Office in the period of 2010 - 2017. The results show that the SDM model for panel data is more suitable than the SAR, SEM models for research data. Moreover, the gross output per capita of a province/city is not only affected by its regular expenditure on education but also by that of neighboring provinces/cities. GDP per capital of a province/city is also affected by the GDP of its neighboring provinces/cities. In addition, control variables such as total investment capital, population size, provincial competitiveness index of local or neighboring provinces also exert a positive impact on the GDP per capita of a province/city. The influence of trained labor on the economic growth of a province/city has not been found.
Public trials in Vietnam: perspective in the sociology of law
Authors: Van Cuong Dang , Van Dong Nguyen
Published: April 2020

The increase, decrease, or even suspension of public trials is a controversial issue and has captured special attention from lawmakers and social activists. This is also an issue that needs addressing in the process of judicial reform in Vietnam. Although public trails are considered as an effective tool for educating and disseminating legal knowledge to the public, they have many shortcomings and disadvantages that need to be remedied. It can be understood that public trial or open trial is a trial open to the public at a location out of a court, from the perspective of crime prevention for a long time, we consider this as a measure to contribute to limit the causes of the crime through influencing the will of objectives, first of all, the prosecuted. This paper focuses on reviewing and analyzing the practice of public trails in Vietnam and their impact on the family of the prosecuted and the society, and this paper is mainly analyzed in the perspective of law sociology, as well, thereby proposing some solutions for the policies and conduct of public trials in Vietnam.
The role of top managers’ support in financial accounting information transparency in Vietnam’s public sector
Authors: Van Nhi Vo , Thi Kim Thoa Dau
Published: April 2020

The Vietnamese economy has been strongly integrating with the world economy. As a result, the requirement to provide transparent financial accounting information has been putting considerable pressure on the public sector. Moreover, as the Government is promoting self-sufficiency in the public sector to reduce the burden on the governmental budget, top managers are the main decision-makers to the organizational, personnel, operational and financial issues in their companies. Therefore, the support of top managers can significantly affect the improvement of financial information transparency in the public sector. The research model takes the form of SEM and is evaluated using PLS-SEM methodology on the Smart PLS 3.2.7 software. The results from analyzing data from 164 Vietnam’s public companies confirm that the support of top managers has a direct impact on the accounting information system as observed from intermediate variables that reflect the relationship between top managers’ support and financial information transparency, namely chief accountant’s expertise, the availability and function of the hardware, software and the communication technology network.
The efficiency of implementing financial autonomy at Vietnam National University Ho Chi Minh: situation and solution
Authors: Tien Dung Nguyen , Dinh Hung Nguyen
Published: April 2020

In the world, university autonomy is considered the advanced governance method targeting improving the quality of higher education. In Vietnam, university autonomy, in particular, financing among public universities, has been experiencing the positive outcomes in line with both world trends and general guidelines of Vietnam’s Communist Party. As one of two National universities in Vietnam, Vietnam National University – Ho Chi Minh has been given a high level of autonomy in terms of training, research, financing, international relations, organization, and personnel since it was founded. Its current effectiveness has, however, witnessed negative results in the autonomous aspect, particularly financing. This paper examines the current situation to point out weaknesses and the cause of such weaknesses in financial autonomy effectiveness of Vietnam National University – Ho Chi Minh; this paper also offers some policy implications including (i) reforming the legal framework towards university autonomy, namely financial autonomy among public tertiary education; (ii) financing allocation reform from the state budget; (iii) improved financial autonomy mechanism at Vietnam National University – Ho Chi Minh; (iv) re-organizing the apparatus and improving personnel quality at Vietnam National University – Ho Chi Minh; (v) strengthening monitoring and internal control.

Authors: Viet Bang Nguyen , Ho Hai Nguyen
Published: April 2020

The paper defines and measures key factors affecting the attraction and retention of employees with postgraduate qualifications in HCMC, using both qualitative and quantitative methods. Accordingly, the former is carried out through deep interviews with 15 experts (including 12 directors of the department/district presidents and 3 are lecturers/researchers of universities in HCMC and focus group discussions with ten respondents. The latter is conducted through direct interviews with 287 respondents. The results show that: (i) Employee retention is affected by employee satisfaction, training, career development, salary and welfare, and working environment; (ii) Employee attraction is affected by training, career development, salary and welfare, and working environment. Due to limited resources, the sample size consists of only 287 respondents who are employees working in the public sector (at wards, districts, and departments in the public sector) in HCMC. This is the limitation of the research.

Authors: Anh Hoang Huynh , Quyen Huynh
Published: April 2020

Since the end of the 20th century, nanomaterials such as carbon nanotubes (CNTs) have been considered as one of the greatest achievements in the field of material science. Nowadays, further research on CNTs is still being conducted to unfold the full potential of this material. Generally, CNTs production methods have been extensively studied, specifically on CNTs synthesis route via liquefied hydrocarbon gas in the presence of a catalyst. From the synthesized material, further investigation including characterization and investigation of this nano size system’s effects on the physics, chemical, mechanical rules applied to macroscopic (bulk materials) and microscopic systems (atoms, molecules). In this present work, we demonstrated the research results of the synthesis of nano-carbon materials from a liquefied hydrocarbon gas (Liquefied Petroleum Gas: LPG) and its application to red phenol absorption in the liquid phase. CNTs used in this study were synthesized by chemical vapor deposition (CVD) method with Fe /ℽ-Al2O3 as the catalyst. The research results demonstrated that CNTs synthesized from LPG in this work were reported to be multi-walled tubes (MWCNTs: Multi-Walled Carbon Nanotubes) with physical characteristics including average internal and external diameters were of 6 nm and 17 nm, respectively. The measured specific surface suggested by BET data was 200 m2/g. The experimental study of red phenol adsorption by MWCNTs showed that the adsorption process followed both Freundlich and Langmuir isotherm adsorption models with the maximum monolayer adsorption capacity of 47.2 mg/g. The research results again showed that it was possible to synthesize MWCNTs from hydrocarbon gas sources via the CVD method by utilizing catalysts. Additionally, red phenol absorption via such material had shown to follow both Freundlich and Langmuir isotherm model, which allow further characterization of this material using Raman, EDX, SEM, TEM, BET, in order to extend the library database on the characterization of the reported synthesized material.
Study on the vase life of Chyrsanthemum indicum cultivar Sakura cutting flower
Authors: Trần Thắng Thanh , Hoàng Triều Phương , Trần Hương Thanh
Published: April 2020

Chrysanthemum indicum cultivar Sakura is one of the daisy cultivars. It is beautiful, but the vase life of cutting flowers is very short. The decrease in flower quality during storage and transportation is a big problem in the flower export. In this study, the morphological, physiological, and biochemical changes during the vase life of cutting flowers were analyzed. The effects of plant growth regulators and sucrose at different concentrations on the vase life of cut flowers were investigated. The vase life of Sakura cutting flowers includes two stages: (1) the growing and blooming of flower, (2) senescence of cutting flowers. During the growing and blooming, the color of disk flowers changed from green to yellow, and the ray flowers continued to expand the dimension leading to an increase in the diameter of the head flower. The senescence of cutting flowers was initiated by the reduction of chlorophyll content in the leaf, which was located at the base. Then, the ray flowers were discolored. In the senescence stage, the respiration rate and the content of the abscisic acid of head flower increased continuously. In contrast, the water absorption, the content of starch, total sugar, salicylic acid, auxin, cytokinin, and gibberellin decreased strongly. The treatment of 10 g/L sucrose, 2 mg/L NAA, 5 mg/L BA, and 20 mg/L salicylic acid in 24 hours extended the vase life of Sakura cutting flowers and the diameter of the head flower.

HEGEMONIC MASCULINITY: Wacana Relasi Gender dalam Tinjauan Psikologi Sosial
Authors: Drianus Oktarizal
Published: April 2020

Today, the world is languishing in a patriarchal structure. This patriarchal domination not only harms women, but also men, children, the elderly, and marginalized groups. Gender mainstreaming extends its studies not only to femininity but to parenting (motherhood and fatherhood), early childhood. In addition, gender also extends to the realm of masculinity or male studies. In this case, the psychology of gender underlines this phenomenon with hegemonic masculinity discourse. Masculinity is seen from the dominance of the spaces of life both public and private. This paper examines the ideology of hegemonic masculinity as the most desirable theoretical response to Critical Men Studies (CSM). This elaboration of the Hegemonic Masculinity concept is useful as a 'binocular tool' that is operational for empirical studies of masculinity.

Mutations in troponin T (TNNT2) gene represent the important part of currently identified disease-causing mutations in hypertrophic (HCM) and dilated (DCM) cardiomyopathy. The aim of this study was to analyze TNNT2 gene exons in patients with HCM and DCM diagnosis to improve diagnostic and genetic consultancy in affected families. All 15 exons and their flanking regions of the TNNT2 gene were analyzed by DNA sequence analysis in 174 patients with HCM and DCM diagnosis. We identified genetic variations in TNNT2 exon regions in 56 patients and genetic variations in TNNT2 intron regions in 164 patients. Two patients were found to carry unique mutations in the TNNT2 gene. Limited genetic screening analysis is not suitable for routine testing of disease-causing mutations in patients with HCM and DCM as only individual mutation-positive cases may be identified. Therefore, this approach cannot be recommended for daily clinical practice even though, due to financial constraints, it currently represents the only available strategy in a majority of cardio-centers.

Published: April 2020

Pulmonary hypertension resulting from chronic hypoxia is at least partly caused by the increased production of reactive oxygen species (ROS). The goal of the presented study was to investigate the dynamics and the site of production of ROS during chronic hypoxia. In our study Wistar rats were kept for 1, 4 and 21 days in an isobaric hypoxic chamber (FiO2=0.1), while controls stayed in normoxia. We compared NO production in expired air, plasma and perfusate drained from isolated rat lungs and measured superoxide concentration in the perfusate. We also detected the presence of superoxide products (hydrogen peroxide and peroxynitrite) and the level of ROS-induced damage expressed as the concentration of lipid peroxydation end products. We found that the production and release of ROS and NO during early phase of chronic hypoxia has specific timing and differs in various compartments, suggesting the crucial role of ROS interaction for development of hypoxic pulmonary hypertension.

Statins, inhibitors of 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase, are effective drugs in the treatment of hypercholesterolemia, however, their undesirable actions are not fully known. We investigated the effects of atorvastatin on the oxidative phosphorylation and membrane fluidity in liver mitochondria, and also on the coenzyme Q (CoQ) content in the mitochondria, liver tissue, and plasma of rats on a standard (C) and hypercholesterolemic (HCh) diet. Atorvastatin was administered at either low (10 mg kg-1) or high dose (80 mg kg-1) for four weeks. The high dose of the drug decreased the concentrations of total cholesterol and triacylglycerols in the plasma and liver of rats on a HCh diet. Administration of atorvastatin was associated with decreased oxygen uptake (state 3), and oxidative phosphorylation rate in the mitochondria of both C and HCh rats. Further, the drug influenced mitochondrial membrane fluidity and dose-dependently reduced concentrations of oxidized and reduced forms of CoQ in the mitochondria. Our findings point to an association between in vivo administration of atorvastatin and impaired bioenergetics in the liver mitochondria of rats, regardless of diet, in conjunction with simultaneous depletion of oxidized and reduced CoQ forms from the mitochondria. This fact may play a significant role in the development of statin-induced hepatopathy.

The cultivation of fast-growing wood (e.g., poplar, willow or black locust) in short rotation coppices and agroforestry systems presents an opportunity for producing biomass sustainably in the agricultural sector. Cost-efficient agricultural wood production requires the availability of high-performance machinery and methods with which high-quality wood chips can be produced at low cost. It is known from harvesting short rotation coppices in practice that both the wood chip quality and the performance of the harvesting machinery depend on a variety of factors (e.g., harvesting method, weather conditions, tree species). That is why this study examines in detail the influence of the tree species (different varieties of poplar, willow, black locust) and the wood condition (fresh, stored or dried, frozen) on the specific energy demand for comminution in a stationary drum chipper and on the particle size distribution of the wood chips produced. For all the tree species examined, the chipping of dried as well as frozen stems was connected with a significant increase in the specific energy demand for comminution. An increase of 31% has been measured if poplar stems are chipped in frozen conditions (max. 6.31 kWh t−1). Drying led to an increase of 59% for dried willow stems (max. 6.67 kWh t−1). Drying and frost had also an influence on the size and quality of the wood chips, but no globally significant connection could be established for the examined tree varieties.

Acinetobacter baumannii is one of the most common causes of nosocomial infections in intensive care units. Its ability to acquire diverse mechanisms of resistance limits the therapeutic choices for its treatment. This especially concerns colistin, which has been reused recently as a last-resort drug against A. baumannii. Here, we explored the impact of gaining colistin resistance on the susceptibility of A. baumannii to other antibiotics and linked colistin resistance acquisition to a gene mutation in A. baumannii. The susceptibility of 95 A. baumannii isolates revealed that 89 isolates were multi-drug resistance (MDR), and nine isolates were resistant to colistin. Subsequently, three isolates, i.e., MS48, MS50, and MS64, exhibited different resistance patterns when colistin resistance was induced and gained resistance to almost all tested antibiotics. Upon TEM examination, morphological alterations were reported for all induced isolates and a colistin-resistant clinical isolate (MS34Col-R) compared to the parental sensitive strains. Finally, genetic alterations in PmrB and LpxACD were assessed, and a point mutation in LpxD was identified in the MS64Col-R and MS34Col-R mutants, corresponding to Lys117Glu substitution in the lipid-binding domain. Our findings shed light on the implications of using colistin in the treatment of A. baumannii, especially at sub-minimum inhibitory concentrations concentrations, since cross-resistance to other classes of antibiotics may emerge, beside the rapid acquisition of resistance against colistin itself due to distinct genetic events.

Biotin protein ligase (BPL) inhibitors are a novel class of antibacterial that target clinically important methicillin-resistant Staphylococcus aureus (S. aureus). In S. aureus, BPL is a bifunctional protein responsible for enzymatic biotinylation of two biotin-dependent enzymes, as well as serving as a transcriptional repressor that controls biotin synthesis and import. In this report, we investigate the mechanisms of action and resistance for a potent anti-BPL, an antibacterial compound, biotinyl-acylsulfamide adenosine (BASA). We show that BASA acts by both inhibiting the enzymatic activity of BPL in vitro, as well as functioning as a transcription co-repressor. A low spontaneous resistance rate was measured for the compound (<10−9) and whole-genome sequencing of strains evolved during serial passaging in the presence of BASA identified two discrete resistance mechanisms. In the first, deletion of the biotin-dependent enzyme pyruvate carboxylase is proposed to prioritize the utilization of bioavailable biotin for the essential enzyme acetyl-CoA carboxylase. In the second, a D200E missense mutation in BPL reduced DNA binding in vitro and transcriptional repression in vivo. We propose that this second resistance mechanism promotes bioavailability of biotin by derepressing its synthesis and import, such that free biotin may outcompete the inhibitor for binding BPL. This study provides new insights into the molecular mechanisms governing antibacterial activity and resistance of BPL inhibitors in S. aureus.

Published: April 2020

Modified blind bolts (Hollo-Bolt) and a locally strengthened steel tube column in the panel zone were created to overcome the moment-resisting problem for the bolted connections between concrete-filled hollow section columns and open section beams and to enhance the performance of connections. The cyclic loading was conducted on a total of six modified anchored blind bolted flush end-plate connections to concrete-filled steel tube (CFST) columns. The key parameters investigated were the tube wall thickness, end-plate thickness, blind bolt anchorage method, and beam section. The failure mode, hysteretic behavior, strength, stiffness, ductility, and energy dissipation capacity of the connections were analyzed and evaluated with all details. The results indicated that connections with modified anchored blind bolts and locally strengthened steel tubes could avoid the premature failure of CFST column and exhibit an improved behavior with a favorable strength, stiffness, and stiffness degradation. The test observations reveal two representative failure modes, and the tube wall thickness and blind bolt anchorage method have a significant effect on the resultant failure mode. Moreover, the use of thin endplate and weak beam can effectively enhance the hysteretic behavior of joints, ductility, and energy dissipation capacity; and the change in anchoring method has little effect on the stiffness. Finite element (FE) analysis models were established for the aforementioned connections. The numerical models were validated against the experimental results and exhibited good agreement. Finally, based on the component method, an initial stiffness calculation method was established for the connections.

Self-piercing riveting (SPR) is one of the mechanical joining processes, and its application to Al/Fe dissimilar materials combination, which is hard to weld, is expanding in the automotive industry. The main process parameters in SPR are types of rivet and die, setting force, and rivet setting speed. Previously, the relationship between the main process parameters and output parameters such as cross-sectional characteristics and joint strength has been studied to optimize the SPR process. In practical applications, there are unexpected and abnormal process conditions such as poor fit-up, angular misalignment, edge offset distance, and inaccurate setting and pre-clamping forces, and their effects on the joining quality have not been discussed. In this study, parametric investigation was performed using an experimental design on SPR joints for 1 mm-thick high strength steel (590 DP) and 2 mm-thick Al alloy (Al5052-H32). The main effect of each level of the abnormal process parameters on the output parameters was statistically investigated, and the analysis of variance was performed for each abnormal process parameter. In the range of abnormal process conditions applied, the set force was the most significant factor affecting the output parameters, and the effect of pre-clamping force on the output parameters was the least significant.

In this research, the authors set out to propose a new method of predicting and adjusting the main cutting parameters of chip machining, namely spraying on the substrate. In the experiments, a total of 28 turning cuts on a Stellite 6 coating layer were realized. The base materials of the Stellite 6 layers were EN S235JRG1 and carbide WC-Co. This work aimed to find out and optimize the influence of different combinations of cutting parameters. Due to the coating solution, the work is focused on the evaluation of the roughness Ra (μm) of the turned substrate, the grain size Dgr (μm) of the spraying, the normal stress σrz (MPa), the residual stress σrez (MPa), the specific cutting force Fc (N), the quality of adhesion to the substrate Adhmp (MPa) and other parameters. For the sake of a comprehensive solution to the problem, several new predictive equations and subsequent suggestions for solutions have been derived from this research topic based on the newly obtained experimental results. The proposed models and procedures make it possible to get new results and insights into coating technologies.

Obesity represents a risk factor for breast cancer development and therapy resistance, but the molecular players underling these links are unclear. Here, we identify a role for the obesity-cytokine leptin in sustaining aromatase inhibitor (AI) resistant growth and progression in breast cancer. Using as experimental models MCF-7 breast cancer cells surviving long-term treatment with the AI anastrozole (AnaR) and Ana-sensitive counterparts, we found that AnaR cells expressed higher levels of leptin and its receptors (ObR) along with a constitutive activation of downstream effectors. Accordingly, leptin signaling inhibition reduced only AnaR cell growth and motility, highlighting the existence of an autocrine loop in mechanisms governing drug-resistant phenotypes. In agreement with ObR overexpression, increasing doses of leptin were able to stimulate to a greater extent growth and migration in AnaR than sensitive cells. Moreover, leptin contributed to enhanced crosstalk between AnaR cells and macrophages within the tumor microenvironment. Indeed, AnaR, through leptin secretion, modulated macrophage profiles and increased macrophage motility through CXCR4 signaling, as evidenced by RNA-sequencing, real-time PCR, and immunoblotting. Reciprocally, activated macrophages increased AnaR cell growth and motility in coculture systems. In conclusion, acquired AI resistance is accompanied by the development of a leptin-driven phenotype, highlighting the potential clinical benefit of targeting this cytokine network in hormone-resistant breast cancers, especially in obese women.
