Robots in education fall into two categories: robots used to teach children about STEM subjects and the more recent application of robots as teachers. The use of robots in education is largely unknown to both researchers and teachers. Developers and educators have questions about essential applications for robots used in education. Educational robots are used to enable students to acquire skills in a range of science, technology, engineering and mathematics disciplines, which are increasingly important in a world where technology is advancing rapidly. The potential for robotic technology to have a profound impact on society, both economically and socially, is enormous. The way people live and work in the world is largely influenced by technology. In order to make learning more pleasant and easier, the education sector is adopting robot teaching assistants in schools. Robotics can be used in education to help develop new methods and strategies. Robotics makes learning easier and thus introduces students to robotics at a young age. In primary education settings, students can learn how to build and program a robot to perform a range of basic tasks.

The Internet of Things, or "IoT" for short, is a modern concept that refers to extending the possibilities of the Internet beyond its natural computer environment to a wide range of other processes and environments. The Internet of Medical Things (IoMT) is a special part of the IoT that is continuously gaining in strength and popularity. The Internet of Medical Things supports traditional health systems by improving their performance by increasing efficiency, effectiveness, reliability and scalability. This paper deals with issues of security and privacy of Internet of Things primarily in the field of medical Internet of Things. The main threats to security are presented first, followed by threats to the privacy of medical Internet of Things. The focus of the paper is on presenting the main models for protecting the security and privacy of medical internet of things.

Charter flights allow fast and secure communications. Since the industrial revolution, traffic has improved so much that its development can be classified as the fastest growing branch of human activity. According to the road on which the traffic takes place, it is divided into: water, land and air (traffic). With the development of economic relations in the world, traffic is improving both the means of transport and the transport routes. Air transport appeared much later than the others. The advantage of air traffic is its speed. For now, this transport is limited mainly to the transport of passengers, while the transport of goods is limited to the transport of postal items, or smaller quantities of goods of greater value, or perishable goods. Air transport as well as the charter itself has primarily an international character. Its real purpose and its economic advantage are fully expressed in the longer air transport over the territory of several countries. With the exception of large states, small states have a first-class interest in using airspace charters over other states. Despite the great importance of charter flights of international organizations, which regulate air traffic, they have not yet regulated this matter with a single international legal act in order to establish uniform standards for this type of transport of passengers and goods.
