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 advent of cloud computing has revolutionized the IT industry, transforming the way organizations store, manage and process data. This paper provides a comprehensive overview of the beginnings of cloud services, tracing their evolution from early concepts to the sophisticated solutions we have today. In addition, the document highlights the main benefits and challenges associated with cloud services. This paper provides a s comparative study of IaaS, PaaS and SaaS, examining their architectures, functionalities and use cases. It explores the similarities and differences between these models, discusses their strengths and challenges, and analyzes their impact on organizations and end users. Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS) are the three main cloud computing service models, each offering different benefits and features. The document also discusses the major players in each category and offers insight into future trends and potential synergies between the three service models.

The primary motive of this research is determining the impact of the Covid-19 pandemic on the highly complex structures such as global supply chains. The research draws conclusions about the current situation and challenges that global supply chains will face in the near future. Therefore, primary and secondary data sources, statistical indicators and researches about the effects of the pandemic on global organizational structures were consulted. The main fact is that Covid-19 pandemic is not only driver of change, but an essential accelerator of the need to restructure global supply chains. Global supply chains that want to maintain or expand their market shares in rapidly changing market conditions are forced to adapt extremely quickly their overall business concepts at all levels of these complex structures. The essential feature of this research is the definition of basic strategic guidelines for efficient adaptation to current and future needs of the global market
