The administrative merger in Southeast Vietnam has fundamentally reshaped regional governance, spatial configurations, and development priorities, creating urgent requirements for a more integrated approach to science and technology (S&T) human resource development. To assess the implications of this restructuring, the study employs a mixed-methods design that combines institutional diagnostics, comparative policy analysis, and quantitative evaluation of workforce indicators. Empirical data are sourced from national statistical agencies, ministerial datasets, provincial development reports, and international benchmarking studies. The analysis focuses on the S&T workforce within the newly configured administrative units of expanded Ho Chi Minh City, Dong Nai, and Tay Ninh, examining competency structures, spatial distribution, coordination mechanisms, and post-merger system dynamics. The findings reveal significant disparities in qualification profiles, weak cross-provincial linkages in training and research, and limited alignment between workforce planning and emergent regional development trajectories. Despite these constraints, the merger presents opportunities to consolidate training capacity, strengthen innovation networks, and enhance talent mobility. The study argues for a coordinated regional S&T human resource strategy supported by institutional harmonization, a functionally differentiated training system, AI-enabled workforce planning tools, and expanded regional–national–international cooperation to advance a knowledge-based, climate-adaptive development pathway for Southeast Vietnam.
This study forecasts electricity demand for Vietnam’s data center sector through 2030 in the context of rapid digitalization and the accelerating adoption of Artificial Intelligence (AI), both of which are expected to exert significant pressure on national power infrastructure. Using a baseline IT load of 524.7 MW in 2025 derived from industry market reports, the analysis employs a scenario-based approach with two growth trajectories: a high-growth case using a 16% CAGR and a market-aligned case using a 12.61% CAGR. Applying a Power Usage Effectiveness (PUE) value of 1.4, consistent with Vietnam’s green data center standards, projected electricity demand increases from 734.6 MW in 2025 to 1,542.8 MW under the high-growth scenario and 1,330.6 MW under the moderate-growth scenario by 2030, corresponding to increases of 110% and 81%, respectively. These findings indicate that the expansion of digital infrastructure will require proactive power system planning. The study highlights the importance of integrating renewable energy through Direct Power Purchase Agreements (DPPAs) and implementing stringent energy-efficiency standards to ensure the sustainable development of Vietnam’s data center ecosystem.
This study explores non-English major students’ perceptions of the ethical use and plagiarism risks associated with Artificial Intelligence (AI) tools in academic writing at Thu Dau Mot University. As AI technologies become increasingly integrated into higher education, concerns about academic integrity, authorship, and originality have intensified. Using a convergent mixed-methods design, data were collected from 108 students through questionnaires and from six participants via semi-structured interviews. Quantitative findings revealed that a majority of students acknowledged the importance of ethical AI use and expressed support for clearer institutional guidelines and teacher training on responsible AI integration. However, uncertainty persisted regarding the ethical boundaries between legitimate assistance and academic misconduct. Qualitative data reinforced these findings, highlighting students’ awareness of AI’s dual role in enhancing writing skills and posing plagiarism risks, particularly through diminished creativity and loss of personal voice. The study underscores the need for localized policies, updated plagiarism regulations, and pedagogical strategies to guide responsible AI use in EFL writing contexts.
AI is transforming English as a Foreign Language (EFL) education by facilitating personalized learning and intelligent tutoring globally. This study examines the readiness and intentions of educators in Thu Dau Mot City, Vietnam, to adopt AI in their EFL classrooms. Through surveys and interviews with 102 teachers and lecturers, results show a high perceived usefulness and intention to integrate AI (M = 4.10). However, challenges remain with moderate ease of use (M = 3.92), low confidence in AI tools (M = 3.68), and limited institutional support (M = 3.45). Qualitative insights indicate a need for systematic training and collaborative environments. The findings emphasize that successful AI adoption relies on institutional investment in training and infrastructure. Without this support, the gap between enthusiasm and actual implementation may hinder AI's transformative potential. Policymakers and educational leaders need to create structured frameworks for effective AI integration in EFL classrooms.
The study investigates the challenges faced by Food Technology students at Thu Dau Mot University in mastering English reading and writing skills. The findings reveal that limited vocabulary and grammar knowledge significantly hinder students' proficiency in these areas. For reading, students struggle with insufficient vocabulary, poor comprehension strategies, and a lack of background knowledge, making it difficult to understand texts, identify main ideas, and interpret references. Similarly, writing is affected by challenges such as improper grammar usage, insufficient vocabulary, awkward phrasing, and issues with sentence construction. Mistakes in punctuation, spelling, and word order further reduce the quality of written work, limiting students’ ability to express ideas clearly and cohesively. These difficulties stem from a combination of linguistic limitations, lack of exposure to English, and insufficient support in structured learning strategies. The study highlights the urgent need for targeted interventions to address these challenges. Proposed solutions include vocabulary enhancement exercises, grammar-focused sessions, structured reading techniques, and writing workshops. Additionally, integrating modern tools like AI-powered learning applications can provide personalized feedback and improve overall proficiency. By adopting these strategies, students can gradually overcome their difficulties, enhancing their reading and writing skills to meet both academic and professional demands. The findings emphasize the importance of consistent practice and tailored learning approaches in language development.
In this study, molecular dynamics simulations were employed to investigate the influence of pressure on the structural properties of silver (Ag) at 300K. The results reveal that an increase in pressure leads to a reduction in nearest-neighbor distance, a promotion of local ordering, and a transition from a largely disordered state to a predominantly face-centered cubic FCC crystalline structure. At intermediate pressures, both hexagonal close-packed HCP and body-centered cubic BCC phases are observed; however, these phases diminish as pressure rises, with FCC becoming the prevailing phase at higher pressures. These findings demonstrate that pressure is a key factor in driving phase transitions and improving crystallinity in metallic systems.
This study explores the motivation and challenges faced by English majored students at Thu Dau Mot University when learning with native English-speaking teachers (NESTs) and non-native English-speaking teachers (NNESTs). Using a quantitative approach, a structured questionnaire was distributed to 50 participants to gather data on their experiences, preferences, and perceptions. The findings showed that students were positively motivated to learn English with both NESTs and NNESTs, although the sources of motivation differed. While NESTs are appreciated for their native pronunciation, interactive teaching methods, and cultural authenticity, NNESTs are valued for their clear explanations, shared language background, and supportive attitudes. The study also highlights challenges associated with each teacher group. It was found that students struggled with understanding native accents and feel intimidated by the fluency of NESTs, while they experienced limited cultural exposure and pronunciation variation with NNESTs. The results suggest that a balanced and inclusive approach to English language teaching - drawing from the advantages of both teacher types - can enhance the quality of language education in Vietnamese contexts.
Effective English communication remains a significant challenge for non-English major students at many Vietnamese universities, often hindering their academic and professional development. This study explores the key difficulties faced by non-English majors at Thu Dau Mot University in English communication and their engagement in classroom speaking activities. Using a mixed-methods approach, the study collected data from 100 students through questionnaires and interviews.
The findings reveal four primary challenges: limited vocabulary, pronunciation difficulties, overreliance on the native language, and lack of confidence. These issues not only affect students’ ability to express themselves in English but also reduce their participation in classroom activities.
Despite these obstacles, the study found that active engagement in speaking activities positively impacts students’ learning outcomes, highlighting the importance of supportive and interactive teaching methods. Engagement varied, with students demonstrating greater participation in structured activities than in spontaneous speaking tasks.
Based on the findings, the study provides recommendations for fostering a more engaging and effective learning environment.
The structural and electronic properties of sulfur-doped armchair stanene nanoribbons (ASnNRs) have been investigated using Density Functional Theory (DFT). The diverse structural and electronic characteristics induced by the substitution of sulfur atoms were comprehensively analyzed through first-principles calculations, including formation energy, optimized structural parameters, projected density of states (PDOS), and spatial charge density distribution. Various doping configurations were considered by replacing Sn atoms with S at different concentrations and atomic positions, resulting in characteristic doping types such as single-atom doping (top-1S, valley-1S), two-atom doping (ortho, meta, para), and full 1:1 substitution with a 6Sn–6S structure. The results reveal significant changes in the bandgap, increasing slightly from 0.26eV in the pristine state to approximately 0.34eV in the meta configuration, moderately decreasing to 0.15eV in the 100% substitution case, and sharply decreasing in the other configurations. Moreover, most sulfur-doped configurations exhibit non-magnetic behavior similar to pristine ASnNRs, while strong magnetism emerges only in the fully substituted 100% case. These findings demonstrate that sulfur doping can fundamentally modify the electronic and magnetic properties of the material, highlighting its potential application in future spintronic devices.
In this paper, Mn-Fe bimetallic nanoparticles were synthesized by simultaneous reduction of a salt mixture of KMnO4 and FeCl3 with glucose as a reducing agent. Degradation of methyl orange in aqueous solution, using hydrogen peroxide as an oxidizing agent, was used to evaluate the catalytic activity of the material. The material was characterized using scanning electron microscopy, X-ray diffraction, and energy-dispersive X-ray spectroscopy. The results showed that cubic manganese oxide nanoparticles were formed at the molar ratio of KMnO4/C6H12O6·H2O = 5/5 and the hydrothermal temperature of 120-220°C, while the oval-shaped structure was formed at the molar ratio of KMnO4/C6H12O6·H2O = 5/40 and the hydrothermal temperature of 220 °C. The cubic Mn-Fe bimetallic nanoparticle was still formed at the molar ratio of Mn/Fe/C6H12O6 = 5/2/5 and the hydrothermal temperature of 120°C, and the methyl orange decomposition efficiency was found to be the highest value of 57% on this catalyst sample.
This study aims to determine and measure the influence of factors attracting domestic tourists to Binh Duong province through quantitative research with 129 domestic tourists, convenience sampling method, data collected from the period from March 1, 2022 to March 31, 2022. There are 5 selected sites: Hoi Khanh pagoda, Dai Nam tourist area, Thuy Chau eco-tourism area, Phu An bamboo village, Cau Mountain - Dau Tieng Lake relic complex. The results of EFA exploratory factor analysis using SPSS software show that there are 5 factors affecting the attraction of domestic tourists to Binh Duong province, including: (1) tourism resources; (2) travel services; (3) tourism products; (4) tourism infrastructure; (5) promotion of tourism. However, the results of the regression analysis show that only the factors "tourism infrastructure" and "tourism resources" affect the ability to attract domestic tourists to Binh Duong, while the other factors donˈt have enough grounds to conclude. On the basis of the research results, this paper proposes management implications to improve the ability to attract more tourists to visit.
Binh Duong Province is one of the regions with very significant population and labor force growth. The development and transformation of the labor structure have positively contributed to the province's labor productivity growth and economic growth, while at the same time contributing to the development of Vietnam in general. This paper combines descriptive statistics, comparisons, contrasts, and trend assessments to identify the characteristics, changes, and transitions in the labor structure of Binh Duong Province from 2015 to 2023. The results show a sustained increase in population and labor force; the labor structure has moved significantly away from the agricultural sector; demand for technical and assembly workers increased sharply; the number of service and sales workers steadily increased and became mainstream. The challenge for Binh Duong Province is that while the group of highly skilled workers is growing, the increase is not evenly distributed; the group of highly skilled professionals is growing rapidly while the group of intermediate-level professionals and secretaries is declining due to replacement by technology.
Due to the limitations of traditional adsorbents for dyeing wastewater, this study combined natural adsorbent (CS, chitosan) and hydroxyapatite (HAp) to form a composite for enhancing the adsorption of aqueous Congo red (CR). The chitosan was prepared from crab shells (Somanniathelphusa sinensis) with a deacetylation degree of about 89%. The HAp and HAp-CS composites were prepared by precipitation in high pH (~10) with the help of concentrated ammonia water (25%). The crab shell chitosan and chitin were characterized by the FTIR method, and the HAp and HAp-CS composites were analyzed using the SEM method. The CR adsorption experiments were carried out in batch form and sampled once for each condition. The results showed that the characteristic peaks in the FTIR spectrum confirmed the success of the crab shell chitosan preparation. The HAp and HAp-CS composites possess porous structures and seem to have a high surface area. The CR adsorptions reached optimal after 5-15 min. contacting, the adsorption efficiency tended to decrease with the initial concentration of CR and increase with the adsorbent dosage. The initial pH of the solution affected the adsorption efficiency for the 70%HAp-CS and 30%HAp-CS composites but had almost no effect on the adsorption capacity of 0%HAp-CS and 50%HAp-CS. The 50%HAp-CS composite had the best adsorption capacity among the synthesized composites (qmax = 769.2mg/g). The adsorption isotherm and kinetics best fit the Langmuir isotherm and pseudo-second-order kinetics model.
The excellent flexibility of graphene materials that allows them to adjust to the curvature of the substrate surface, chemical surface inertness, and impermeability have attracted considerable attention in the past decade as a blending material and an additive in anti-corrosion coatings. In this paper, we present the role of graphene in enhancing the protective properties of anti-corrosion coatings on metal surfaces with the aim of improving the anti-corrosion performance and extending the life of the coating on metal structures, comparing the anti-corrosion ability of graphene with some types of metal oxide materials such as zinc oxide, titanium dioxide. The methods of graphene fabrication and the method of blending graphene into the coating composition give results on mechanical properties, wettability, antibacterial properties, anti-corrosion properties, fire resistance and current research trends in graphene-based coating materials and explore optimal solutions for applications in the paint industry.
This study investigates the structural and electronic properties of Au-doped silicene nanoribbons (SiNRs) under the influence of an external electric field of 0.4 eV/Å, utilizing density functional theory (DFT). The stability and structural integrity of SiNRs following Au doping are assessed, considering two distinct doping configurations: the top configuration and the valley configuration, where each unit cell incorporates a single Au atom. The formation energies of the doped systems are calculated to evaluate their thermodynamic stability based on DFT principles. Furthermore, detailed analyses of the density of states (DOS) and energy band structures are conducted. Both doping configurations exhibit metallic characteristics, indicating potential applicability in future nanoelectronic devices.
In this paper, the structural properties of crystalline and polycrystalline Cr have been investigated using molecular dynamics simulations. The interaction between atoms is modeled via the MEAM potential. Periodic boundary conditions are applied in the x, y, and z directions. The structural characteristics are analyzed through the total energy function, heat capacity, radial distribution function, and angle distribution. Dynamics are evaluated through the analysis of mean squared displacement and diffusion coefficient. The results show that the melting temperature of crystalline Cr is higher than that of polycrystalline Cr, indicating that the polycrystal melts earlier. This information is important when considering material applications in high-temperature environments.

English language proficiency is crucial for academic and professional success, with effective communication skills playing a pivotal role. Collaborative teaching methods, particularly group work, can significantly enhance students' creativity, evaluation, synthesis, analysis, and comparison, as well as problem-solving, essential for developing collaborative abilities. Furthermore, non-English major students often struggle to develop their speaking skills due to limited practice opportunities. This study addresses this challenge by implementing group-work activities in an English as a Foreign Language (EFL) classroom. A mixed-methods approach was used to gather data including quantitative data collected through a questionnaire administered to 71 non-major students at Dong Nai Technology University and qualitative data came from semi-structured interviews. The results showed that group work significantly improved students' fluency, coherence, and confidence. Students reported increased motivation and engagement in speaking activities. These findings suggest that group-work activities effectively enhance speaking skills for non-English major students.
The act of picking fruit is very familiar and associated with the history of hunting, catching, gathering, and gathering of humans, so they have come up with many types of tools for this job. The practice of wrapping fruit in bags before harvest has only been applied recently, so it is still very new and rudimentary. These tools only perform each function individually. Therefore, the author has inherited and proposed a tool that has two functions at the same time: wrapping bags and picking fruit at high altitude. This article presents the structure, operating principles, and instructions for using this tool. This tool is compact, inexpensive, and easy to use. It consists of a long handle, a set of clamps that close and open, and a control cable connecting from the top to the middle of the handle. Farmers just need to stand on the ground, put the clamps over the fruit, and pull the control cable to make the clamps close or open. From there, they can wrap bag or pick fruits from high above easily. This research will help farmers have a tool that has two functions, which certainly has many advantages and is useful for farmers.
Keywords: cloth bags, cover fruit bags, fruit pickers, plastic bags, tools.
This article's primary goals are to provide design drawings, a description of the
structure, an explanation of the working principle, and a kinematics calculation for text
stamping machines. This machine has an electric motor, a gear-pinion transmission, a
rotating disc-rod-slider mechanism and a hinged four-way mechanism. This is a simple,
reasonably priced and useful device for administrative agencies' workstations. An
ordinary administrative worker can also operate it. This device is about the same size
as a laptop or printer.
It operates by clamping the seal, stamping constantly onto A4 pages. The stamping
speed can also be changed by varying the shaft speed of the electric motor. It is
convenient, but it also has the disadvantage of requiring someone to put the paper in
and take it out.
The box frame of this machine is made of plastic or wood. Some transmission
components are made of steel. When this machine works, the force applied to it and the
force caused by it are very small, so in general it is very simple and safe.
Keywords: Gear transmission – rack, rotating disc mechanism – connecting rod –
slider, four-hinged mechanism, stamping machine.
In this topic, we applied the Fmincon function to the optimum question when choosing the structure of a 7-bar bearing steel bearing, divided into groups of the same size, including group 1 (1, 2 bars), group 2 (3, 4, and 5 bars), and group 3 (6, and 7 bars) with three fixed head points and two bearing points. Using the Matlab software code, we have identified the structures of each group of steel bars corresponding to the radius of 1.564 cm, 3.509 cm, and 4.724 cm, respectively. Through this, we can identify the 1, 2, and 3 bars that are resistant to traction; the 3, 5, 6, and 7 bars that are subject to compression; and the 4 bars alone that are not subject to the action of the force. The results show that using the optimal method, we choose the different sizes, thicknesses, and volumes of the pipe so that it best suits the technical requirements of the paper, to avoid waste of raw materials, affecting the economic cost.

This study which entitles “Learners’ Attitudes towards the Project Works in promoting English learner autonomy: a Case Study at Foreign Trade University-Ho Chi Minh Campus” was conducted with the following objectives: (1) to investigate students’ attitudes towards the use of project works to enhance their autonomous learning in an English speaking class; (2) to find out to what extent students believe that using project works can promote their autonomous learning; and (3) to figure out difficulties that learners have during the time they conduct Video making project. The study population was 73 second-year students who took the course English listening and speaking 2. An open-ended questionnaire and semi-structured interview were employed as research instruments for data collection. The result firstly shows that the students have positive attitudes towards the use of project works in English class that may have enhanced their autonomous learning. Then, it reveals students’ preference in having more project works to do in their English classes. Nonetheless, using project works’ evaluation as one of criteria for course assessment is a controversial issue among these students. In addition, students’ interest in utilizing information technology devices is remarked as one of the significant findings in this study. Furthermore, some difficulties when conducting projects are found including time constraints, teamwork conflicts, cultural differences and technology problems. In short, because of students’ positive attitudes toward Video making project in enhancing their autonomous learning, it is suggested that teachers should consider applying the project in their language teaching.
International students’ experiences are a major concern for universities and educational researchers. Globally, Vietnam is a top source country for international students but little is known about their experience.
This study explores the everyday experiences of 10 Vietnamese master’s students from a New Zealand university through a series of semi-structured in-depth interviews. A qualitative approach enabled me to capture the essential meanings of the participants’ experiences and understand what it was like to be Vietnamese students in New Zealand.
In academic settings, the students initially struggled to deal with a range of problems related to language and communication. These made them feel overwhelmed and bewildered. During these formative months, many of them experienced language difficulties. These difficulties forced them to learn to deal with challenges and become independent.
This research helps universities become more aware of the experience of foreign students studying at the host universities, and thereby take measures to support them in their studies and daily life.
