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.

Over several decades, a combination of historical, economic, and political factors have influenced the multifaceted phenomenon of Vietnamese return migration from Cambodia. This article examines the return migration of Vietnamese from a historical perspective with document and contextual analysis, revealing a broader picture of the socio-economic and political dynamics in Cambodia and the historical relationship between Cambodia and Vietnam. Before the 1990s, return migration was significantly influenced by colonial-era migration policies and pervasive anti-Vietnamese sentiments. These factors led to violent repression and forced evictions under regimes such as Lon Nol and the Khmer Rouge, profoundly impacting the Vietnamese community in Cambodia. In contrast, administrative governance and economic factors have become the key determinants of Vietnamese return migration in the contemporary period. Understanding the underlying causes and mechanisms that create the situation for Vietnamese in Cambodia and their return is crucial, serving as a basis for addressing their current challenges and promoting their social integration in both countries.

This article's primary goals are to provide design drawings, a description of the structure, an explanation of the working principle, and a kinematics calculation for text stamping machines. This machine has an electric motor, a gear-pinion transmission, a rotating disc-rod-slider mechanism and a hinged four-way mechanism. This is a simple, reasonably priced and useful device for administrative agencies' workstations. An ordinary administrative worker can also operate it. This device is about the same size as a laptop or printer. It operates by clamping the seal, stamping constantly onto A4 pages. The stamping speed can also be changed by varying the shaft speed of the electric motor. It is convenient, but it also has the disadvantage of requiring someone to put the paper in and take it out. The box frame of this machine is made of plastic or wood. Some transmission components are made of steel. When this machine works, the force applied to it and the force caused by it are very small, so in general it is very simple and safe. Keywords: Gear transmission – rack, rotating disc mechanism – connecting rod – slider, four-hinged mechanism, stamping machine.
