3D printing technology is an emerging technology in recent years, which can achieve rapid display of objects through the feeding method. It has been widely used in various industrial sectors. Higher vocational and technical colleges are one of the important ways to cultivate higher technical personnel from various industries. They must keep up with the pace of educational reform and introduce 3D printing technology into corresponding classrooms. Under the guidance of the course "Fundamentals of Mechanical Design", this article utilizes 3D printing technology to apply common PRO/E to products, achieving various motion mechanisms, making the originally monotonous classroom teaching lively and allowing students to immediately showcase their creativity.

Under the background of the development of the network information age, the current Internet industry has obtained more development opportunities, but it has also brought corresponding challenges in the process of wide application. In the development and construction of modernization, society pays more attention to the supervision and determination of the characteristics of online public opinion. From the perspective of the current characteristics of network public opinion, because social information is more extensive and involves many fields, network public opinion has a high degree of complexity and diffusion. Therefore, it is necessary to strengthen the analysis and application of relevant data mining systems in order to achieve efficient management of network public opinion. The key to the disadvantage of the traditional excavation of public opinion communication characteristics lies in the lag of the excavation process, and it is difficult to deal with malignant public opinion in a timely and effective manner. Therefore, in order to truly solve the lagging problem of public opinion data dissemination feature mining technology, it is necessary to strengthen the application of artificial intelligence technology in it.

The construction of practical education bases in the construction of medical colleges in vocational colleges is an important way to meet the teaching requirements of medical courses and reflect the comprehensive practical education ability of vocational colleges. For medical students in vocational colleges, the improvement of practical ability is also an important way to continuously enhance and improve their professional and technical abilities. This article analyzes the construction of relevant training bases in the field of medical imaging, and explores the scientific methods for teaching and constructing traditional Chinese medicine imaging professional bases in vocational colleges through four typical paths: basic construction of practice bases, effective management of practice bases, targeted practical abilities, and professional skill training for cultivating teacher teams.

In recent years, science and technology have continued to develop and progress, and the level of teaching digitalization has improved. Music education occupies an important position in many universities, and it is necessary and feasible to use digital technology to explore its impact in basic education. The digitalization and technology of music education in colleges and universities have had a positive impact on basic education, such as balancing educational resources, updating education models, optimizing teaching platforms, and practicing student-oriented concepts. In order to maximize the role of digital technology, it can be innovated and applied from sight-singing ear training teaching, orchestration course teaching, and polyphonic course teaching.

The widespread application of computer-aided production technology can effectively and directly assist enterprises in completing all aspects of production smoothly and efficiently. With the rapid development of 3D printing application technology, research and promotion of new material manufacturing applications have basically begun. This article mainly focuses on analyzing two technologies: computer-aided technology and 3D printing technology.

Orientation: Indeed, the 4th industrial revolution (4IR) has redefined the world of work. A new set of skills needs to be defined and made available to organisations. Human resource management practices now operate in a complex, interconnected, unpredictable, and evolving environment. The question that one needs to answer is: how can HR align its functions to meet the demands of the fourth IR? It is prudent that human resource functions evolve quickly and adapt to changing demands. Research purpose: This paper seeks to unpack the changes that have been brought about by the 4IR and suggest ways in which HR professionals in Lesotho can align with this inevitable era of digitalisation. Motivation for the study: Due to the dynamics and transformations that have been brought about by the 4IR, this study was motivated by the need to understand the effects of the 4IR in small economies on the HR function and offer lessons to embrace change. Research approach: The research was qualitative in nature, and data was collected purposefully from journal articles, newspapers, and book chapters. Content analysis was used for the data analysis. Research findings: The effects of the 4IR through digitalisation disruptions have been felt across all corporate functions, and HR is no exception. It has had a massive influence on both the economy and the labour force and impacted employee roles in terms of health, mobility, working hours, personal life, and general administration. HR leaders play a critical role in ensuring that businesses are able to successfully adopt and deploy new technologies. Contributions: The research unpacks the effects of 4IR and gives practical lessons for HR professionals in Lesotho.
