The existing stand-alone multimedia machines and online multimedia machines in the market have certain deficiencies, so they cannot meet the actual needs. Based on this, this research combines the actual needs to design and implement a multi-media system based on the Internet of Things and cloud service platform. Moreover, through in-depth research on the MQTT protocol, this study proposes a message encryption verification scheme for the MQTT protocol, which can solve the problem of low message security in the Internet of Things communication to a certain extent. In addition, through research on the fusion technology of the Internet of Things and artificial intelligence, this research designs scheme to provide a LightGBM intelligent prediction module interface, MQTT message middleware, device management system, intelligent prediction and push interface for the cloud platform. Finally, this research completes the design and implementation of the cloud platform and tests the function and performance of the built multimedia system database. The research results show that the multimedia database constructed in this paper has good performance.

BACKGROUND Preclinical training on manikins is a key component of dental medicine education. Preclinical practice on traditional manikins and real clinical practice shows massive differences. Specifically, preclinical training on traditional manikins is inefficient. OBJECTIVE The aim of this study is to describe a manikin with a multimedia system and evaluate its effectiveness in preclinical dentistry training. METHODS A total of 159 students participated in this study. Amongst these students, 80 used traditional manikins (Group TM) for preclinical practices, including cavity preparation and full-crown preparation, and 79 used a manikin with a multimedia system (Group MM). The cavity preparation scores and full-crown preparation grades of the two groups were compared. The students and teachers completed a final questionnaire survey to evaluate their experience of preclinical practices using the manikin with a multimedia system. RESULTS Group MM performed better than Group TM in the preclinical practices of cavity preparation and full-crown preparation. The final questionnaire results indicated that students in Group MM were satisfied with the clarity, simulation, helpfulness in mastering operation points quickly and improvement in operation proficiency provided by the manikin with a multimedia system. The teachers were satisfied with the teaching effect of the manikin with a multimedia system and had a high opinion of the students’ mastery. CONCLUSIONS The results of this study indicated that manikins with a multimedia system are a good alternative traditional manikins in preclinical dentistry training.

Information communications technology (ICT) is currently a highly sought component of every higher learning institutions, especially universities and colleges gravitate towards eLearning mode of instruction and knowledge acquisition. eLearning encompass multiple technology and Internet-based learning platforms that requires computer literacy from both learners and instructors. eLearning has been upgraded such that it offers more flexibility and comfort as instruction and learning occurs any time and at the users’ preferred environment. However, for most African Universities, the challenge in the use of eLearning is expedited by excess number of students, poor infrastructural development and poor access to the Internet off campus. At the University of Botswana, the need and urgency to address aforementioned difficulties was exposed in the era of COVID-19 pandemic where the use of eLearning was a dare situation for both instructors and learners. In this article, the authors discuss the background of eLearning tools at the University of Botswana, types of eLearning tools, their relevance, use, advantages and the challenges encountered. Prospects are also discussed. The article is based on the experiences of the authors, their observations, as well as the literature review and the use of the social constructionism or social constructivism theory.
