Based on a proposed four-step process, the paper illustrates the design of a digital game integrated with the mathematics curriculum for second grade. The findings of this research are to provide practical guidance for teachers in designing digital educational games, thereby augmenting the effectiveness of their pedagogical practices.

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.

Enzyme immobilization offers an innovative approach for reuse, preservation, and optimization of production efficiency and costs in the food and biofuel industries. In this study, amylase enzymes immobilized in Ca-alginate membranes were utilized in the fermentation of traditional sticky rice wine. The morphology and activity of immobilized amylase beads were maintained effectively at a 2% concentration of both carrier material and enzyme solution. After seven days of fermentation, fermentation efficiency reached an ethanol concentration of 55% v/v. The activity of immobilized amylase retained 60% of its activity after four consecutive fermentation cycles. These results suggest that immobilized amylase beads have promising applications in sticky rice wine production, replacing free amylase, which is difficult to recover and reuse.

Conductivity is a crucial and widely recognized concept in material science, particularly significant in the study of low-dimensional systems. This research extends the analysis of the conductivity tensor within a quantum well with infinite potential, focusing on electron-acoustic phonon scattering. The system is subjected to two external fields: an electromagnetic wave and a laser field. The study explores the detailed effects of these external fields, noting that significant impacts occur only at high frequencies. Among the factors affecting conductivity, the amplitude of the laser field is the most influential. Additionally, when the electromagnetic wave frequency exceeds 1012 s-1, its impact on conductivity becomes considerable.

Fall prevention represents a vital clinical indicator in healthcare settings and serves as a fundamental element of patient safety. This study aimed to evaluate nurses’ knowledge, attitude, and practices on fall prevention in caring for patients as well as explore the relationship between knowledge, attitude, and practices on fall prevention in patient care. This study was conducted on 312 nurses working in four selected level II government hospitals in Ho Chi Minh City from August to October 2024. The majority of nurses were female, with diplomas or BSNs, averaging 39.2 years old and 15.8 years of clinical experience. 77.9% attended a fall prevention training course. Most nurses showed moderate knowledge (66.7%) and practices (mean score of 3.26/5) regarding fall prevention, while their attitudes were generally positive (mean score of 3.92/5). Strong correlations were found between knowledge, attitude, and practices, as well as with prior training and education level (p < 0.001). Factors such as age, work experience, education, and training were predictive of fall prevention practices. Furthermore, attitude partially mediated the relationship between knowledge and practice. In summary, the study highlights the importance of fall prevention training, improving knowledge and attitudes, and considering factors like work experience and education in nursing practices. The mediating role of attitude suggests that fostering a positive attitude is key to better fall prevention practices, emphasizing the need for targeted educational programs that enhance both knowledge and attitudes to improve clinical outcomes.

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.

Eosinophilic gastroenteritis (EGE) is a rare condition characterized by eosinophilic infiltration into the gastrointestinal tract. Symptoms are often non-specific and gastrointestinal in nature, such as nausea, vomiting, abdominal pain, diarrhea, weight loss, and malabsorption. Diagnosis is primarily based on clinical findings, laboratory tests, imaging, and histopathological examination through endoscopic biopsy. Treatment involves corticosteroids, proton pump inhibitors (PPIs), and dietary modifications. This article presents the case of a 15-year-old male diagnosed with eosinophilic gastroenteritis with a history of cow’s milk allergy. The patient was treated with systematic corticosteroids (1mg/kg/24h), PPIs (esomeprazole 40mg/day) and elimination dietary therapy (peptide-based formula), resulting in positive clinical outcome. Through this case, we emphasize the importance of early diagnosis and appropriate management in handling this rare disorder.

Tourist motivation is a critical aspect of tourism research, providing valuable insights into why people travel and what influences their destination choices. This article aims to provide a systematic review of the leading models used to understand tourist motivation, examining both psychological and external factors that drive tourist behaviours. Key frameworks such as Maslow’s Hierarchy of Needs, Push-Pull Theory, and Iso-Ahola’s Motivation-Relaxation Model are explored to highlight the various intrinsic and extrinsic forces that motivate tourists. Additionally, models like Plog’s Psychographic Typology and the Travel Career Ladder offer valuable perspectives on how travel motivations evolve with experience and personality traits. By synthesizing these diverse models, the review not only provides a broad understanding of tourist motivation but also underscores the complexity and multidimensional nature of travel behaviour. Understanding these models is essential for tourism practitioners, as it enables more targeted marketing strategies, improved destination management, and enhanced visitor satisfaction. This article aims to contribute to a deeper understanding of the motivations that shape tourism trends and to offer a framework for future research in the field.

In this study, the Wave Optics chapter, which is part of the General Physics A2 course for first-year Electrical Engineering students at Thu Dau Mot university, will be taught using the KWL (Know-Want to know-Learned) strategy. Creating a three-step KWL instructional process for four major Wave Optics chapter topics, creating learning scenarios that use the KWL strategy, and evaluating the technique's effects on students' critical thinking, active learning, and knowledge retention are all parts of the research objectives. Both qualitative and quantitative data analysis techniques are used in this study. Two classes were chosen at random: the experimental group (49 students) was taught using the KWL strategy, while the control group (49 students) followed a traditional instructional method. Data were collected through test scores, post-lesson surveys, and classroom observations. The findings show that the experimental group achieved an average score of 7.31, higher than the control group’s 6.13. Post-lesson surveys indicated that all 15 evaluation criteria reached a "Good" level, with mean scores ranging from 4.24 to 4.54. Students responded positively, expressing enjoyment in being able to ask questions, synthesize information, and engage more deeply in learning. The study confirms that the KWL technique is an effective teaching method that enhances instructional quality and promotes students’ active learning skills. This strategy holds potential for broader application across other STEM subjects to maximize learner-centered knowledge acquisition.

This is a descriptive study to find out students’ awareness about the benefits and harm that they have experienced from using the AI tools during their learning process. The study was founded on a survey and an interview among majored-English students at Thu Dau Mot University. The data was then This descriptive study aims at finding out students’ awareness about the benefits and harm that they have experienced from using AI tools during their learning process. A four-section survey including open and closed-ended questions was sent out, and 193 majored-English students at Thu Dau Mot University responded randomly. The striking finding is that although students preferred AI tools to support their learning, they themselves accepted the benefits gained and the challenges faced were just a little over the average. In particular, the participants confirmed that AI tools contribute much to the fast speed of their academic work completion, but AI also makes them passively think, become inflexible, and somewhat limit the ability to equip knowledge for their English language competence.

This paper explores the identity of Bình Dương Province through its place names, highlighting how these names reflect the region's historical, cultural, and economic transformation. Bình Dương, once a primarily agricultural province, has experienced rapid industrialization and urbanization; and how the evolution of place names mirrors these shifts, encapsulating themes of resilience, pride, and modernity in the province’s identity. Applying the Toponymic Analysis method to analyze the etymology, origin, and meaning of 3,462 toponymic words consisting of 4,155 subtypes of place names discovered in 91 communes and wards of Binh Duong province, the findings reveal that place names in Bình Dương not only serve as geographical markers but also function as symbols of Binh Duong identity. The place names are often closely tied to the region’s geography; reflect the rich cultural mix of its inhabitants; carry traces of colonial influence; have presented political and economic changes; serve to unify its population, invoking themes of strength, resilience, and local pride, equality. This research implies that toponymy is a powerful tool for understanding social and cultural identity of a place.

In particular, the ability to solve mathematical problems is one of the core elements of mathematical ability, helping students develop key knowledge and skills and creating opportunities for students to experience and apply practical mathematics. The study proposes some measures to foster students' mathematical problem-solving capacity in teaching the topic "Algebra" (Math 10). Teaching practice shows that the proposed measures are appropriate and feasible, initially contributing to improving the quality of teaching and meeting the goals of educational innovation specified in the General Education Program math pass 2018.

Fractional differential equations are an important branch of mathematics and have been considered under many different fractional derivatives. Among them, differential equations with Riesz-Caputo fractional derivatives have also attracted the attention of many researchers. Studying differential equations that may have singularity coefficients is more difficult than usual because they require several complex techniques. In the present paper, we consider a nonlinear pantograph differential equation where the source function may have a temporal singularity. Using the contraction principle, we prove that the problem has a unique solution under some appropriate conditions. Furthermore, we define a new type of Ulam-Hyers stability and show the main equation of the problem is stable in the mentioned sense. To obtain the main results, a new inequality is proposed and proved. Some examples are constructed to confirm the validity and feasibility of the theoretical results.

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.

The paper analyzes the radial distribution power system with the series connection of FACTS devices, which is easily implemented using a formula from the power flow equation (PFE - power flow equation) with the voltage magnitude and power flow on the lines are treated as independent variables. When control variables such as the form of reactive power at nodes and lines are directly manipulated in the formulation, the application of FACTS device control operations in the power system is carried out quickly and directly. Using the ratio matrix at the nodes of a radial distribution system is primarily represented on the main diagonal to reduce computational procedures. All FACTS device models are unified under static stability conditions and can be easily integrated within the new framework through the process of "variable exchange". Using the IEEE standard system, the formulation of the formula is based on the trend on the line - Line Flow Based (LFB) by the author to provide easy implementation with multiple FACTS devices connected in the system and its efficiency.

The rising demand for automation in agriculture and manufacturing necessitates efficient, cost-effective sorting systems to replace labor-intensive manual processes. This paper introduces an innovative system integrating a Siemens S7-1200 Programmable Logic Controller (PLC), LabVIEW-based image processing, and OPC (OLE for Process Control) communication for automated tomato sorting. Utilizing real-time vision analysis, the system classifies tomatoes by color and size, offering a low-cost, scalable solution tailored for small-scale industries. A high-resolution camera captures images, processed in LabVIEW using HSV color space and size thresholds, with results relayed via OPC to the PLC, which actuates a stepper motor-driven sorting mechanism. Experimental validation in a controlled setting achieved 92% sorting accuracy and a throughput of 60 tomatoes per minute, surpassing manual sorting in speed and consistency. The modular design supports scalability to other agricultural products, enhancing its practical utility.

Asia’s financial ecosystems, while distinct from Western paradigms, remain underexplored. This study integrates cultural finance, regime-switching machine learning, and ESG asymmetries into a novel analytical framework tailored to Asia’s unique financial architecture. We develop three models: a Hybrid LSTM-GARCH for crisis forecasting, a Bayesian Structural Equation Model capturing informal institutional dynamics, and a machine learning-enhanced Difference-in-Differences model to assess ESG impacts. Theoretically, we propose the Cultural-Statistical Nexus Framework, embedding sociocultural variables into predictive finance, the concept of institutional plasticity to explain regulatory divergence, and ESG Arbitrage Theory to highlight sustainability’s dual role as risk mitigator and speculative signal. Empirically, Confucian Risk Aversion reduces corporate leverage by 15 percent, ESG adoption lowers systemic risk but increases greenwashing, and hybrid models outperform conventional tools in FX crisis prediction. Practical implications include cultural-risk-adjusted capital buffers, AI-based liquidity tools, and region-specific ESG strategies, advancing a globally inclusive paradigm of financial science.

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.

Waste in the production process causes waste of resources and resources while not creating real value, which is a major threat, reducing the competitiveness of enterprises. One of the measures that can both improve productivity and reduce costs effectively for enterprises is line balancing. Line balancing effectively maximizes idle time at stations, minimizes the number of workstations as well as uses fewer workers and equipment while still ensuring the company's production output and significantly increases production efficiency. The article focuses on the production line of Vancover Dining chair backrest clusters at Thanh Thang Limited Company. The actual production line still has some problems such as many stages of semi-finished products and too much idle time at some other stages. Therefore, the study proposes a method of rearranging the line in a U-shape to balance the production line to optimize the production process, but also from eliminating non-value-added activities. By reducing waste, enterprises not only save costs but also achieve increased output and shortened production time.

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.
