Emerging virtual reality and augmented reality (VR/AR) technologies in education have the potential to revolutionize the whole educational experience. Studies have shown that before introducing the technology to their pupils, educators should do a thorough assessment of the technology's viability and possible acceptance in the classroom. However, not much is synthesized from the body of knowledge about the leadership and coupling of VR and AR in education, including its trends and direction of research in other domains. In this article, the bibliometric and content analysis has shown that interest in virtual reality and augmented reality has increased from 2018 to 2022 in the Web of Science database. The patterns formed from Vosviewer in the bibliometric analysis have also portrayed that Virtual reality (VR) and Augmented Reality (AR) are used in many fields, including education, medicine, arts, engineering, business, and marketing. Other results from data mining showed the authors with the most publications in the field, their affiliated universities, and the source of publications. In the wake of the Covid-19 epidemic, these findings may also help improve educational opportunities for all students and the quality of instruction they receive. As implications, Virtual reality (VR) and augmented reality (AR) harness current technology to put digital content in the actual world, enabling consumers to have a more meaningful interaction with it on desktop or hand-held devices. This bibliometric research shows that animation, 3D graphics, and sound may replace more traditional ways of schooling in the future.

China has been through a period of remarkable urban sprawl since the reform and opening-up policy in 1978, with the highest urbanization occurring in the coastal zones. Sustainable urban development requires a better understanding of the spatiotemporal characteristics of urbanization. This study systematically explored urban sprawl in Chinese coastal cities with a visual interpretation method from 1979 to 2013. The results show that urban built-up areas kept increasing at a faster pace during the study period (i.e., increased about 9-fold in 34 years), especially in the first decade of the 21st century. Spatially, urban sprawl intensity generally peaked in the urban fringe. Urban built-up areas expanded mostly at a cost to cultivated land and non-urban built-up land, and became more irregular and less compact through the study period. Land-use policies, economic development levels, port developments and locations are all closely related with urban sprawl in these port cities. The results also suggest that improving the utilization efficiency of urban land and coordinating the development of city and port are necessary and important for sustainable development in coastal cities.
