International integration not only brings opportunities but also challenges for teaching and learning English. Like other universities, Thu Dau Mot University focuses on teaching English for non-majored students of different faculties to meet the curriculum as well as provide knowledge for them to be confident when communicating. However, teaching English to non-majors still faces a lot of difficulties due to a number of factors. This study aims to understand the attitudes of non-English major students toward learning English at TDMU. Quantitative methods are used through survey questionnaires related to students' attitudes toward learning English and factors affecting students' attitudes toward learning English, and also finding out their wishes when participating in English learning activities in class. The questionnaire was sent to 190 students of different levels (levels 3-5). The results of the study show that most students are aware of the importance of learning English but they are not highly motivated to learn. According to the analysis results, students do not have a positive attitude towards learning English for the following reasons: They haven't spent time studying because they have to work part-time job for paying tuition fee; The purpose of using this language after graduation has not been determined, and they haven’t found a suitable learning method. From these findings, some solutions have been discussed to improve students' English learning attitudes, help lecturers make appropriate adjustments to improve students' learning outcomes and meet the standards school output as well as meet the needs of society.
Binh Duong Province is one of the leading regions in Vietnam in attracting foreign investment, with thousands of expatriates living and working in the province. The demand for an international education environment (in-country study abroad) among parents and students in the province is increasing. Additionally, the current globalization trend and international integration demand a high-quality workforce with adaptability and international integration skills, requiring educational institutions to innovate to keep up with the rapidly changing society. Given the situation and trends, establishing an international high school under Thu Dau Mot University (TDMU) is necessary to meet the demand for high-quality human resources in Binh Duong Province, serving the economic, social development, and international integration of the province, the Southeast region, and the whole country. Furthermore, the establishment of an international high school by TDMU also contributes to enhancing TDMU’s position, image, and reputation within the national and international education systems. This article analyzes the strengths, weaknesses, challenges, and opportunities of TDMU in establishing an international high school, thereby providing implementation directions in the context of the economic and social situation in Binh Duong Province.

The study investigated algorithms for processing the gamma spectrum of PVT detectors. Various commonly used algorithms and algorithms were examined for handling the gamma spectrum of PVT detectors. During the research, the Energy Weighted Counts (EWC) algorithm was selected and implemented to process the gamma spectrum using simulated data of gamma scattering spectra on PVT detectors. Specifically, the energy-weighted algorithm was applied to effectively differentiate between the gamma spectra of three important isotopes Cs137, Co60, and I131. The results of the study demonstrated the success in meeting the specified requirements, especially in selecting the optimal algorithm for identifying the three isotopes on the PVT detector, all achieved through the utilization of the GEANT4 simulation software. This research not only provided a detailed insight into gamma spectrum processing but also proposed an effective algorithm using simulation software to explore and evaluate algorithms on PVT detectors. This marked a significant step in the research and development within this field.
This article investigates the physical layer security (PLS) performance in an Energy Harvesting Underlay Cognitive Radio Network (EHUCRN). Firstly, the article examines the impact of parameters such as primary transmitter power, interference power threshold, and expected security level on EHUCRN's Secrecy Outage Probability (SOP). Then, based on the findings, the article evaluates the PLS performance of the system. The results indicate that increasing the primary transmitter power reduces the PLS performance while raising the interference power threshold improves PLS performance. Furthermore, increasing the expected security level decreases the PLS performance. Additionally, the percentage of time spent collecting energy increases within a small range, resulting in an increasing PLS performance up to a peak value. However, if this percentage continues to increase within a large range, the PLS gradually decreases. Moreover, the results demonstrate that the PLS performance in EHUCRN is low due to relatively high SOP values.
The article explores the influence of the mother tongue (Vietnamese) on practicing to develop first-year students’ English writing skills at Thu Dau Mot University. Analytical data was collected from 100 first-year students majoring in English Language at the Faculty of Foreign Languages - Thu Dau Mot University. Research results show that students are still greatly influenced by Vietnamese (first language) in the process of practicing English writing skills. Among the students surveyed, up to 58.4% said they were still influenced by the way of thinking in Vietnamese, and then switched to English to follow the writing style of Vietnamese. … The remaining % said they had practiced writing in English through many writing activities at English centers and had practiced writing through thinking in English. The rest of the article proposes some solutions to help students overcome the above barriers to develop effective writing skills.
ABSTRACT Nowadays, parents' needs are increasing to choose toys, especially painting colors, that are both beautiful, ensure their children's health, and are also environmentally friendly. In the production of industrial painting colors, waste from steps in the watercolor production line, if not treated to meet environmental standards according to regulations, will become a huge hazard to the environment and human health. human. Including causing skin, eye, digestive, and respiratory allergies. Causes poisoning, disease, cancer... Destroys the aquatic environment, trees, pollutes rivers and lakes. When building an industrial painting colors production line and putting it into use, if you do not think about solutions to treat wastewater from the production process, it will not be able to operate long term. Wastewater from color factories is mainly heavy metals contained in painting colors such as lead carbonate, oxide, and metal salts containing cadmium chromate. These substances cause mass death of organisms in the water, and polluted water cannot be used for agriculture. This research uses two main methods: experimental research to create products; combined with the questionnaire survey method to get customer opinions after using the painting colors test. Research results show that painting colors products made from fruits and vegetables combined with beeswax and coconut oil are very eye-catching and receive positive feedback from customers. With the im of protecting children in the future and responding to the green environmental message in the world, we hope that safe painting colors products from vegetables and fruits will be popularized in the community in the future. Keywords: vegetables, painting colors, environmental protection, safe products, beeswax.
In physics, the majority of natural events have been researched and described using differential equations, each having its own initial and boundary conditions. These differential equations contain a large number of fundamental constants as well as other model parameters. They add to the equation's complexity and rounding errors, making the problem more difficult to solve. In this work, we provide a method for transforming these physics differential equations into dimensionless equations, which are significantly simpler. Nondimensionalization, by suitably substituting variables, is the process of removing some or all of the physical dimensions from an equation that contains physical quantities. Some benefits of these dimensionless equations include that they are simpler to identify when using well-known mathematical methods, need less time to compute, and do not round off errors. Through several examples we discuss, this method is useful not just in quantum mechanics but also in classical physics.

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.
Phytoremediation is an ecofriendly that has shown promising results for the contaminants like heavy metals. Because of its advantages as a cost-effective, efficient, environment- and eco-friendly technology based on the use of metal-accumulating plants. This paper aims to compile some information about heavy metals of arsenic, cadmium, lead, copper and zinc (As, Cd, Pb, Cu and Zn) sources, effects and their treatment. It also reviews deeply about phytoremediation technology, including the heavy metal uptake mechanisms and several research studies associated about heavy metals (As, Cd, Pb, Cu and Zn) and aquatic plants are used to process these heavy metals.
Diatomite from Tuy An district, Phu Yen province, with different purities and diatom integrity as catalyst carriers, were adopted to prepare TNTs/g-C3N4 composite catalysts by a sol-gel method, with an optimal weight ratio of 1:1 for TNTs/g-C3N4 and diatomite. Compared with pure TNTs, g-C3N4, and TNTs/g-C3N4, the obtained composite photocatalysts exhibited lower photocatalytic performance under the same conditions and NO removal within 30 min under visible light. The NO gas treatment efficiency under the same conditions with different catalyst supports only decreases by approximately 18% at a reaction rate of 0.0950 min-1. This research on composite photocatalysts is a promising step towards practical environmental remediation. The use of diatomite as a carrier for photocatalytic materials is particularly noteworthy, as it is a naturally available and cost-effective source of materials. However, further improvements in the photocatalytic performance of the composite material are necessary to fully realize its potential in environmental remediation, including removing NOx and other pollutants. Overall, this study provides valuable insights into the influence of carriers on the photocatalytic activity of composite photocatalysts and lays the foundation for future research in this field.
Hoi An is a well-known travel destination for both Vietnamese and foreign visitors, not only because it has a cultural heritage recognized by UNESCO but also because of its other cultural resources, including craft villages. Serving as both attractions and experiences for tourists, craft villages give them the opportunity to create unique mementos of their vacation while also boosting household income and elevating the status of craft villages. How is Hoi An's tourism industry exploiting this resource in tourism? The article conducts a scientific investigation of the role and current state of crafts in the production of souvenirs for tourism in general, particularly in Hoi An's craft villages such as Thanh Ha pottery and Kim Bong carpentry village, using research on souvenirs, observation techniques, and field excursions. The findings demonstrate that handicraft souvenirs are few, have less appealing designs, and have to compete hard with souvenirs from other localities. These results will facilitate the collaborative efforts of Hoi An's tourism stakeholders to identify strategies that guarantee the advantages that tourism brings to craft villages and vice versa.
This research examines the scholarly literature on technology-based language learning published in the Computer Assisted Language Learning journal-one of the key journals in the field from 1990 to 2019. The researcher randomly selected 30 articles from 257 articles found in this journal during a thirty-year period (one article each year) to analyze the research method trends and the learner types focused in those studies. 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.

Sustainability in land use plays an important role in the urbanization process toward achieving the goals of the 2030 Agenda for Sustainable Development. This study integrates Earth observation data through satellite imagery analysis combined with field surveys to assess the Urban Land Use Efficiency (ULUE) by using the land use efficiency index, estimates the relationship between land use, population growth, and the urbanization process in Thang Loi ward over a 20-year period. The findings reveal inefficient urban land use, where the expansion rate of built-up areas exceeds the population growth rate in the studied area. From 2002 to 2022, the population and built-up area increased by 339% and 460%, respectively. In most of the expanding areas, there is widespread hoarding and fragmentation of land use, with numerous plots of land being vacant or underutilized for many years due to lack of control. Therefore, to improve land productivity and ensure sustainable urban growth, the local government should consider improving the Urban Land Use Efficiency Index.
In this paper, MIL-53(Al) was synthesized by solvothermal method and its application as an adsorbent to remove rhodamine B from aqueous solution. The material was characterized using X-ray diffraction, Fourier-transform infrared spectroscopy, nitrogen adsorption-desorption isotherms, and scanning electron microscopy. The results show that the material has a large specific surface area (1028.3 m2/g). The rhodamine B adsorption on MIL-53(Al) occurs very quickly in the first minutes of contact. Two pseudo-first order and pseudo-second order adsorption kinetic models, and two adsorption isotherm models, including Langmuir and Freundlich, were used to analyze the adsorption data.

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 this note, we prove a unique result for a nonlinear differential equation concerning a Nagumo-type source. An example is given to illustrate the theoretical result.
Political culture is a complex concept, containing many different understandings and research methods from many different perspectives. Studies of political culture have emerged since World War II, and scholars continue to discuss this concept in the context of many inconsistent views in the academic world because of the interdisciplinary nature of this concept. Based on research results on the definitions, functions, and relations of political culture with organizational culture and management culture; by secondary qualitative data analysis method; this article concludes that the most similar point between the definitions of "political culture" is the recognition of the relationship between political culture and the state, with society with nation-state and class, the recognition that the inner meaning of political culture always includes dynamic elements as well as static elements, and acknowledges that the subject of political culture can be studied at all three levels of the individual, institution (organization), and community (state, nation).
