The application of Artificial Intelligence (AI) in education is rapidly transforming the teaching and learning landscape in Vietnam. AI technology is being integrated into various educational platforms to provide personalized learning experiences, support educators, and enhance the overall efficiency of the education system. In Vietnam, AI is utilized to develop adaptive learning programs, intelligent tutoring systems, and automated administrative processes. AI-powered tools such as virtual teaching assistants and chatbots are also being employed to offer real-time support and feedback to students. Furthermore, AI-driven data analytics is used to monitor and improve student performance and engagement levels. AI assists teachers in automating grading, reducing assessment time, and enabling speech recognition systems to evaluate students’ English-speaking skills. These innovations contribute to a more dynamic, interactive, and inclusive educational environment. However, challenges such as data privacy concerns, the digital divide, and the demand for a skilled workforce remain significant. Addressing these issues is crucial for the sustainable integration of AI into Vietnam’s education sector.
In the early 21st century, China has increasingly recognized the critical importance of securing its national energy supply. As the demand for energy continues to rise, China has implemented an assertive and comprehensive energy diplomacy strategy on a global scale, with Southeast Asia emerging as a key focus. The region holds a geo-strategic significance, rich in vital natural resources such as oil, natural gas, and other minerals, making it a strategic partner in China’s broader energy security objectives. This policy, driven by China’s growing energy needs and its desire to diversify energy sources, has far-reaching impacts on Southeast Asia, influencing various sectors including economics, politics, and national security. China's energy diplomacy in Southeast Asia is not only an economic endeavor but also a means of strengthening political alliances and asserting its regional influence. This paper explores the nuances of China's energy diplomacy policy towards Southeast Asia in the early 21st century, highlighting its strategic objectives, the mechanisms employed, and the broader implications for regional and global security dynamics.
Digital transformation in education is an inevitable trend and has been increasingly promoted in Vietnam over the past few years. The application of digital games in mathematics instruction not only alleviates students’ stress and pressure but also fosters engagement and motivation in the learning process. This paper clarifies key concepts related to digital games as well as presents a set of principles and a design process for digital games using the web-based application Pink Cat Games. 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.
Mathematics education contributes to the formation and development of students' key qualities, general abilities and mathematical abilities. 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.
