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.

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.

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.

Results showed that mixed-method research has been more popular in recent years, and this may help academics better understand the connections between classroom environments and technology-enhanced language acquisition. For quantitative analysis, tests and Liker-scale questionnaires are the most used instruments, whereas interviews are the most common approach for qualitative analysis in mixed-method publications. Additionally, when it came to learning levels, researchers focused their attention on college and university students, but they paid no attention to pre-schoolers.

Abstract: Urban agriculture is a highly concerned issue during the period of rapid urbanization in Vietnam. Research aims to propose a cultivation process for cultivating oyster mushrooms, utilizing coffee grounds from coffee businesses as a resource. This approach promotes circular economy principles, generating economic benefits for households while protecting the environment and being suitable for urban areas. The study conducted experiments on grey oyster mushrooms using different mixtures of coffee grounds and rubber wood sawdust at the following ratios: 0%, 25%, 50%, 75%, and 100% coffee grounds/rubber wood sawdust, filled into bags with a weight of 1.2kg. The research results showed that disease infection rates were mild in the 0% and 25% mixture ratios, while the remaining ratios exhibited moderate to severe infection levels. The highest mushroom yield was observed in the mixture ratio of 25% coffee grounds, with an average number of mushroom ears per bag reaching 29.7grams/bag, the dry weight is 63.8 grams/bag, with an average size ranging from 3 to 14 cm and a moisture content of 79.5%. The fastest colonization speed on the substrate is achieved by 25%, 50% coffee grounds blend, which fully colonizes the bag in a period of 25 to 35 days, the shortest time compared to the 75% and 100% coffee grounds blends, which take 40 to 45 days. The experimental results show that the 25% coffee grounds: 75% rubber sawdust blend is suitable for urban mushroom cultivation models and can be expanded on a large-scale farm, contributing to minimizing environmental pollution, utilizing limited urban land area, and providing high economic efficiency.

In engineering and science problems, the data being considered are often known in the form of sets of discrete points, not as a continuous function. In applications, the values of the discrete data at specific points may be required to estimate. To solve these problems, a common mathematical approach is to use the interpolation method. In this paper, we use the cubic natural spline interpolation method to build approximate functions for some real data in Vietnam such as data on rice output and rice area of cultivation, data on expenditure and income per capita. The data used in this paper are extracted from the General Statistics Office of Vietnam. We develop some Matlab programs to find the coefficients of splines and calculate the values of the interpolation functions at specific points. Using the obtained interpolation function, some missing values in the data on income and expenditure per capita in the Southeast region of Vietnam in 2019 and 2021 are estimated. Furthermore, some unknown data on rice productivity and cultivation area are obtained in a similar manner. A good agreement between the calculated values and actual values are found.

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.

In this study, we examine students at Thu Dau Mot University specializing in Food Technology’s speaking and listening skills in English. We conducted a survey on 59 students majoring in Food Technology using the questionnaire approach. Students struggle to develop macro-English abilities like speaking and listening, as seen by their responses. mastering English grammar, vocabulary, and other micro-skills might be challenging. The findings indicate that significant obstacles to learning listening and speaking skills include a lousy sound system, a lack of a communicative context, a limited vocabulary, a lack of cultural understanding, and a fear of making mistakes in communication. The findings also demonstrate that students’ limited exposure to English and weak phonological skills are to blame for their difficulty acquiring pronunciation. Many words are long and complicated, making learning and recalling word parts like verbs, nouns, and adjectives challenging. Many words are also difficult to pronounce. Learning the grammar of verbs and articles is challenging for students. When the challenges are solved, this research aims to effective foreign language learning.

In the current work, we study a Cauchy problem for a time-fractional pseudo-parabolic equation with a globally Lipschitz source term. We prove the unique existence of a mild solution to the problem, by the common Banach fixed point theorem. This solution is then verified that exists globally in time by Gr¨onwall’s inequality. Compare to previous works about the similar issuse, we approach in a way that does not require using weighted spaces. Although our approach share a similar spirit to previous studies, our method seems to be more precise and natural.

Premarital sex is one of the issues that female migrant workers currently face. This increases the risk of sexual and reproductive health issues among this vulnerable group. The article's goal is to comprehend and explain the attitude of female migrant workers regarding premarital sex while also analyzing the factors that influence their attitudes toward this issue. The theories of social control and migration are the foundation for this objective. The combined approach used in this paper collects quantitative data from 420 female migrant workers and qualitative data from seven female migrant workers who participated in in-depth interviews. According to research findings, female migrant workers are considerably more agreeable to premarital sex if both are voluntary, but they do not feel ready to discuss premarital sex with those around them. The level of education and length of residence are factors that affect how female migrant workers feel about the premarital sex concern. In order to enhance their autonomy and reduce risky sexual behaviors, we can thus propose that female migrant workers, especially those with a residence length of more than five years, should have greater reproductive health capacity, including reproductive health knowledge and skills.

Oral history is both a method of gathering information and an important source of historical data in social history and public history. The narratives of individuals are not only exploited to find historical facts or “additional” details to a grand narrative but uncover the meaning of individuals’ stories for a broader social context. That shift has made oral history increasingly an interdisciplinary research method. However, compared with the popularity of oral history in international academic disciplines, the application of this research method restricts in Vietnam. This article presents the possibilities and prospects of oral history through different research topics/fields in history, at the same time, specify the causes of obstacles to the legitimization of oral history in Vietnam.

Cho Lon was a former province in southern Vietnam, now part of Ho Chi Minh City and Long An Province. During the Vietnam War from 1945 to 1954, Cho Lon province exemplified the practice of an all-people, all-out war across military, political, economic, and cultural fields. Using the method of writing history through oral narratives, this paper presents the process of organizing and developing general education in Cho Lon province in conjunction with the resistance movement led by the Democratic Republic of Vietnam. The results show that the Democratic Republic of Vietnam in Cho Lon province organized and developed general education throughout the resistance, even during the most intense periods of the war. The development of general education in Cho Lon province became an integral part of the resistance, contributing to its momentum and strength, and helping to achieve victory in the fight against French colonial invasion. The educational development in Cho Lon province from 1945 to 1954 provides valuable lessons for building an educational system during wartime.

ABSTRACT With the ever-increasing development of technology, online teaching is more readily accepted as a viable component in teaching and learning, and blended learning, the combining of online and face-to-face learning, is becoming commonplace in many higher education institutions. Definitely, challenges cannot be denied; however, it has been suggested and deployed globally including Vietnam. To some extent, both teachers and students present their positive points of view on this learning approach. However, there are a huge number of students expressing their lack of understanding the blended learning, which negatively affects their attitudes towards deployment of this learning approach as well as particular reference to motivation and interest. This paper is to assess the English majors’ perceptions on blended learning environment at tertiary level, which especially affects their learning the writing skills. Results of the study are absolutely helpful for the author to understand the students’ perceptions of the effects on the blended learning; then, she can give some suggestions to enhance the learning of writing skills in the light of blended learning.

Abstract: The article is based on data from the research program "Greater Mekong Subregion Flood and Drought Risk Management and Mitigation Project (ADB-GMS1)" jointly implemented by the Asian Development Bank (ADB) and the Ministry of Agriculture and Rural Development, and the Vietnam Institute of Water Resourches Research in Tien Giang and Dong Thap province. The results show that, in recent years, due to the increasingly severe global climate change, the intensity of various types of natural disasters occurs more frequently, irregularly and with greater intensity. This has greatly affected the production, daily life and properties of the people in the vulnerable areas. To reduce the impact of various types of disasters on people living in vulnerable areas, it is necessary to combine two types of solutions in disaster prevention, namely construction solutions and non- construction solutions. In which, non-construction solutions play a very important role, namely, people living in communities are considered as the main actors in preventing and mitigating disaster risks occurring in the community.

High power losses are a great concern in operating electric distribution system. Reconfiguration is one of the most economic approaches for reducing power losses of the system. This study suggests a technique for dealing with the distribution system reconfiguration problem based on a water cycle algorithm for minimizing active power loss. The water cycle algorithm is a recently developed metaheuristic algorithm that inspired the process of water circulation for solving optimization problems. The effectiveness and performance of the water cycle algorithm were tested on the 33-node and 69-node systems. The water cycle algorithm was applied to determine the best configuration of the distribution system for active power loss minimization. The results yielded by the water cycle algorithm were compared with other optimization algorithms in the literature and the comparisons showed that the water cycle algorithm obtained good quality of solution for the problem. Therefore, the water cycle algorithm is the potential method for the distribution system reconfiguration problem.
