Agricultural tourism (agritourism) has become an emerging development pathway in the Mekong Delta, where agriculture, culture, and water-based ecosystems intersect to form distinctive rural landscapes. Within Vietnam’s broader agenda of rural restructuring and sustainable development, agritourism in the region has gradually evolved from small-scale household initiatives into a more organized sector shaped by the interaction of state policies, enterprise strategies, and community participation. This study examines how these three actors collectively influence agritourism development in the Mekong Delta. Using a qualitative research design and an embedded case study approach, the analysis draws on national and provincial policy documents, industry reports, and representative agritourism models such as My Khanh Tourist Village, Con Son Community Cooperative, Con Chim Ecotourism Site, Con Ong experiential farm, and the Dinh Yen Mat weaving craft village. The findings indicate that since 2010, the Vietnamese government has established a policy framework promoting experiential agriculture-based tourism, regional connectivity, climate-resilient development, and cultural preservation, thereby enabling enterprises to upgrade facilities, diversify tourism services, and expand regional tour circuits. At the same time, local communities have reorganized tourism activities through cooperative and community-based models that integrate agricultural practices, culinary heritage, and craft traditions into visitor experiences. Successful initiatives demonstrate improvements in income generation, employment opportunities, cultural continuity, and environmental awareness. However, agritourism in the Mekong Delta still faces challenges, including fragmented policy implementation, limited destination management capacity, weak interprovincial coordination, repetitive tourism products, and environmental pressures associated with climate change. The study argues that the sustainability of agritourism in the region depends on strengthening the alignment between policy frameworks, enterprise innovation, and communitybased stewardship.

Proton exchange membrane fuel cells (PEMFCs) have attracted significant attention due to their high efficiency and low emission characteristics. However, the cell performance is strongly influenced by operating conditions and membrane properties, which are difficult to investigate comprehensively by experimental approaches alone. This study develops a complete electrochemical model of a single PEM fuel cell in the MATLAB – Simulink environment based on the voltage loss mechanisms including the Nernst potential, activation overpotential, ohmic losses, and concentration losses. The model is employed to quantitatively investigate the effects of operating temperature, hydrogen partial pressure, oxygen partial pressure, and membrane thickness on the polarization characteristics (I – V curves) of the PEMFC. Simulation results indicate that increasing temperature significantly enhances activation kinetics and improves cell voltage, while elevated oxygen partial pressure yields the most pronounced performance improvement among gas parameters. Conversely, increasing membrane thickness leads to higher ohmic losses and voltage degradation, especially in the high –current – density regime. The proposed model provides an effective numerical tool for teaching, system analysis, and preliminary optimization of PEMFC operating conditions.

This mixed-methods study examines how fourth-year English majors at Thu Dau Mot University engage in Zalo-based classroom discussions. Using a convergent parallel design, data were collected through a questionnaire (N = 112) and semi-structured interviews (N = 8) to explore behavioral, cognitive, and emotional dimensions of engagement. Findings reveal that Zalo is primarily used for task coordination and passive monitoring, with limited proactive discussion. Students value its functions for planning and language accuracy but perceive discussions as low in intellectual depth. Emotionally, Zalo fosters social connection and comfort in interacting with peers and lecturers but also introduces pressure to keep up and reluctance to express dissent. The study highlights Zalo’s dual role as a facilitator of convenience and a constraint on deeper learning, suggesting the need for intentional instructional design to promote critical thinking and inclusive dialogue.

This study forecasts electricity demand for Vietnam’s data center sector through 2030 in the context of rapid digitalization and the accelerating adoption of Artificial Intelligence (AI), both of which are expected to exert significant pressure on national power infrastructure. Using a baseline IT load of 524.7 MW in 2025 derived from industry market reports, the analysis employs a scenario-based approach with two growth trajectories: a high-growth case using a 16% CAGR and a market-aligned case using a 12.61% CAGR. Applying a Power Usage Effectiveness (PUE) value of 1.4, consistent with Vietnam’s green data center standards, projected electricity demand increases from 734.6 MW in 2025 to 1,542.8 MW under the high-growth scenario and 1,330.6 MW under the moderate-growth scenario by 2030, corresponding to increases of 110% and 81%, respectively. These findings indicate that the expansion of digital infrastructure will require proactive power system planning. The study highlights the importance of integrating renewable energy through Direct Power Purchase Agreements (DPPAs) and implementing stringent energy-efficiency standards to ensure the sustainable development of Vietnam’s data center ecosystem.

In this study, molecular dynamics simulations were employed to investigate the influence of pressure on the structural properties of silver (Ag) at 300K. The results reveal that an increase in pressure leads to a reduction in nearest-neighbor distance, a promotion of local ordering, and a transition from a largely disordered state to a predominantly face-centered cubic FCC crystalline structure. At intermediate pressures, both hexagonal close-packed HCP and body-centered cubic BCC phases are observed; however, these phases diminish as pressure rises, with FCC becoming the prevailing phase at higher pressures. These findings demonstrate that pressure is a key factor in driving phase transitions and improving crystallinity in metallic systems.

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.

The study aims to explore factors influencing middle school students' motivation to learn. Instead of assuming a general decline in motivation, it objectively examines the issue through research, identifying key influences such as curriculum difficulty, teaching methods, and external pressures. By analyzing survey data from eighth-grade students at Chu Van An Middle School, the study provides evidence-based insights into the challenges affecting student engagement in learning. This research aims to identify the factors affecting the learning motivation of middle school students to help them become more engaged in their studies. In this study, the author designed a survey questionnaire of 8 questions combined with a quantitative method to identify the factors causing a lack of interest in learning among middle school students. The survey was conducted at Chu Van An Middle School in Binh Duong Province. The survey participants were 375 eighth-grade students in the 2024-2025 academic year. According to the survey, 184 male students felt uninterested in learning due to various factors, accounting for 49.07%; 157 female students, accounting for 41.87%; and 34 students of other genders, accounting for 9.07%. Given this situation, it is urgent to propose feasible solutions to help students regain interest in learning.

Vocational guidance plays an important role in career orientation for secondary students. Before entering the secondary school graduation exam, schools around the country start to organize career counseling. This urgent issue drives parents, teachers, and students up the wall, especially students are the learners who directly suffer from this consequence leading to students’ mental health issues. The study aim is to find out the optimal solution that helps students overcome the high pressure of vocational counseling before the graduation exam. In this inquiry, quantitative research is the best method to focus on surveying students’ awareness based on comparative research which is typical research, and via this exploration to evaluate the research object comprehensively. The comparative research is applied in this article to discover the differences between vocational guidance before and after the 10th-grade entrance exam towards poorer and lower-scoring students. This study is put into operation at Chu Van An secondary school – in Binh Duong province – academic year 2023-2024 and the students of grade 9 are research objects which are chosen to answer survey questions. According to survey tables, more than 93.3% of students with poorer and lower scores select vocational guidance after the secondary school graduation exam and 6.7% of students take the reverse one. What we need to think about is whether this way of present career counseling is feasible

It is very common to stabilize the preset value (Wanted value) of analog signals such as temperature, pressure, weight, flow, speed in automatic control. However, these control objects often have some problems such as overshooting, taking a long time to bring the system to a steady value, and large errors. One of the most used systems to overcome these problems is the PID, which is a preset stabilizing system with a quick function that returns the system to the set value in a short time without overshooting. error is close to zero. However, determining the scale parameters Ki, integral Kp, and differential Kd for the system to work optimally is a problem that needs to be studied. This paper presents how to accurately determine differential, integral, and scale coefficients according to 3D virtual reality model. Used a lot in simulation modeling for training and practical applications.
