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 Impact Ranking reflects the impact and contribution of universities around the world, including Vietnam, to the community towards the 17 sustainable development goals of the United Nations. The purpose of this study is to evaluate the ranking results of Vietnamese universities in this ranking and the sustainable development goals that they are pursuing. The results show that from only one Vietnamese university among 467 global universities ranked in 2019, there are now 13 Vietnamese universities out of 1,936 global universities in the rankings. In addition to the mandatory SDG17, most Vietnamese universities mainly focus on the 8 SDGs related to economy, health, education, peace, equality and community (SDG1, SDG3, SDG4, SDG5, SDG8, SDG10, SDG11, SDG16). However, few universities focus on the goals related to poverty and environmental resources (SDG2, SDG6, SDG7, SDG9, SDG12, SDG13, SDG14, SDG15). This situation poses great responsibility and challenge for Vietnamese universities in accompanying the world in realizing the goal of sustainable development. This study is a reference resource for Vietnamese universities to identify sustainable development goals that should be prioritized in their short-term and long-term plans when participating in THE Impact rankings, in order to contribute to building a peaceful, just and prosperous society

Results indicate that FLC offers superior performance, exhibiting reduced power fluctuations and faster responsiveness to environmental changes compared to IC and P&O. These insights contribute to enhancing PV system efficiency and reliability in modern power grids.
Sesuvium portulacastrum was shown to absorb sodium (Na+) and clor (Cl-) from the soil and accumulate it within its tissues. Therefore, it was chosen as a good plant for the phytodesalination of saline soils. The present study aimed to evaluate plant capacity to accumulate cloride ions and the potential to desalinize in saline soil medium of this halophyte. The results show that S. portulacastrum has a high tolerance at salt concentrations from 0.5% - 5% in growth terms of stem height, number of branches level 1, root length, and fresh biomass. Plants absorb a marked Cl- ions content clorideine and accumulate in roots, stems, and leaves. The efficiency of salt removal is 92% in the treatment of NaCl 1%. These results contribute to reducing soil salinity, so it is possible to apply sea buckthorn to treat saline soil environments.
Improving and exploring the photocatalytic performance of composites for new models continues to pose a challenge. Here, a straightforward thermal dispersion method is achieved by incorporating nitrogen (N) into TiO2 at different weights (1%, 3%, and 5%) to enhance photocatalytic activity. The material properties are analyzed through ultraviolet-visible diffuse reflectance spectroscopy (UV-VIS DRS), and X-ray diffraction (XRD). The results indicate that the NO gas removal efficiency of N-TiO2 photocatalytic materials is higher than that of pure TiO2 after 30 minutes of exposure to visible light. The highest NO gas treatment efficiency of N-TiO2 -1% is 40.4%, with a reaction rate following a first-order kinetic equation of 0.0688 min-1. Successfully fabricating N-TiO2 photocatalytic materials using the thermal dispersion method, with significantly enhanced photocatalytic performance under visible light activation, will benefit practical applications, particularly in the environmental sector.

Abstract The 2023 air quality assessment was conducted at five key industrial sites (Song Than II Industrial Zone, Thuan Giao Industrial Cluster, Thuong Tan Quarry, My Phuoc II Industrial Zone, Bau Bang Industrial Zone) in Binh Duong province, aiming to evaluate the potential air pollution in surrounding areas and the health impacts on workers in nearby residential areas. The survey results for several air pollution parameters, including NO2, total suspended particulates (TSP), and noise levels from the 2023 monitoring data provided by the Center for Environmental Monitoring and Technical Resources in Binh Duong province, indicated that at the Thuong Tan Quarry, TSP concentrations ranged from 26.0 to 374.8µg/Nm3, exceeding the standard by 74.8µg/Nm3 according to QCVN 05:2023/BTNMT. Noise levels at the quarry ranged from 59.7 to 72.1 dB(A), exceeding the standard by 2.1 dB(A) according to QCVN 26:2010/BTNMT. Additionally, air quality monitoring results at various industrial sites in Binh Duong indicated that the annual average levels of air pollutants at these industrial zones met the permissible limits set by QCVN 05:2023/BTNMT and QCVN 26:2010/BTNMT, with TPS concentrations ranging from 11.5 to 374.8µg/Nm3, noise levels from 57 to 72.1 dB(A), and NO2 concentrations from 18 to 85.5µg/Nm3. According to the 2023 air quality results, air quality in industrial zones has relatively improved compared to previous years, although some monitoring points still exceed the regulatory limits. Due to the different nature of production activities at the quarry compared to other industrial sites, more dust and noise are generated, necessitating management measures for production equipment and technological changes.
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.
Sustainable development is a crucial issue that has been particularly emphasized by the Party and the Government of Vietnam, especially in areas with a large population of ethnic minorities. The Southern Central Highlands is currently home to nearly 50 ethnic groups, among which local ethnic minorities such as the Ê Đê, K’ho, and M’nông are striving to develop their economy, culture, and society sustainably. However, this development process faces numerous challenges from both objective and subjective factors, including natural conditions, government development policies, ethnic psychology, and religious factors. At present, Catholicism and Protestantism are the two main religions within the ethnic minority communities of the Southern Central Highlands. Introduced to the region from the late 19th to early 20th century, these two religions flourished in the second half of the 20th century and have become major elements in the spiritual lives of the communities. Religion has had and continues to have significant impacts on the economic, cultural, and social development of local ethnic minorities, contributing positively to the process of sustainable development. This article uses data collected from the community through participant observation, in-depth interviews, and survey questionnaires to analyze the impact of religion on the economic, cultural, environmental, and social aspects of local ethnic minorities in the South Central Highlands in the context of sustainable development.

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.

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.
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.

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.
