In this paper, a mathematical model and solution for performing the inventory tasks of a multi-user, mixed warehouse in which neither satellite positioning nor other IT solutions can be used was presented. After reviewing the literature on road planning and the use of drones in warehouses, a method is presented that can be used to control drones that can be moved in all directions for imaging and transmission. The proposed method consists of three main steps. As a first step, we provide the mathematical model and solution method needed to determine the (optimal execution time) access routes required for processing the compartments of the warehouses. This is an initial step before starting the inventory. This considers the structure of the warehouse, its features, the number of drones, and the parameters of the drones. In the second step, based on the routes obtained in the first step, the real-time movement of the drones was controlled during processing, including camera movement and image recording. The third step is post-processing, i.e., processing the images for QR code identification, interpreting the QR code, and recognizing empty compartments for inventory control. A major advantage for users of the solution method is that the result can be achieved automatically without an external orientation device, relying solely on its own movement and the organization of a pre-planned route. The proposed model and solution method are suitable not only for inventory control, but also for solving other problems matching the model.

Nowadays, the theme of computer thinking is a common topic for educational research. The scientific literature on the subject has gradually appeared, in which psychologists emphasize the need for the development of thinking of children. Research often relates only to the development of computational thinking at elementary and high schools. Nowadays, almost everything is digitalized, so it is important to also develop the computational thinking skills of students at higher levels. In our study, we present the results of the conducted data analysis in which we examined the development of students’ efficiency. On the basis of the results, we propose a possible solution for the development of computational thinking. Using data research processes, we examined the results of the object-oriented (OO) planning and programming subject of Budapest Business School, going back 5 years. The results show that the level of particular computational thinking could be measured using the exam results, and teacher advancement (experience) improved the level of particular computational thinking. Today, education has been greatly influenced by COVID-19, challenging not only teachers but also students. The production of particular computational thinking under COVID-19 or online is much more effective than the pursuit of full computational thinking through traditional teaching.

In this study, a model and solution are shown for controlling the inventory of a logistics warehouse in which neither satellite positioning nor IoT solutions can be used. Following a review of the literature on path planning, a model is put forward using a drone that can be moved in all directions and is suitable for imaging and transmission. The proposed model involves three steps. In the first step, a traversal path definition provides an optimal solution, which is pre-processing. This is in line with the structure and capabilities of the warehouse. In the second step, the pre-processed path determines the real-time movement of the drone during processing, including camera movements and image capture. The third step is post-processing, i.e., the processing of images for QR code identification, the interpretation of the QR code, and the examination of matches and discrepancies for inventory control. A key benefit for the users of this model is that the result can be achieved without any external orientation tools, relying solely on its own movement and the organization of a pre-planned route. The proposed model can be effective not only for inventory control, but also for exploring the structure of a warehouse shelving system and determining empty cells.

Industry 4.0, or the fourth industrial revolution, means the automation of industrial processes, digitalization and the use of data in order to increase the efficiency and quality of production processes. Industry 4.0 also affects other areas of the economy, as well as education. The concept of Education 4.0 strives to modernize and apply education to the age of Industry 4.0 using new technologies and methods. The main goal of Education 4.0 is to prepare students for the challenges of Industry 4.0 and to give them skills and knowledge that they will need in the digital age. This new educational model is no longer only about the transfer of information, but also focuses on developing students' abilities and renewing their problem-solving skills. Education for student-centered education aims to increase student motivation, develop individual skills and improve learning outcomes. To implement Education 4.0, educational institutions need to provide the infrastructure and infrastructure that enables students to use digital technologies and virtual learning. For students, Education 4.0 also includes interactive learning opportunities such as online courses, videos, and interactive learning materials. In this article, we present the methods and thematic units that should be taught so that students can meet the challenges of Industry 4.0.

We present a solution based on blockchain technology and smart contracts for agile project management in light of the continuing transition in the software development industry. Due to the fact that these technologies are self-executing, customized, and impervious to tampering, they are considered to be crucial for the transition to a more efficient, transparent, and transactive payment gateway between major stakeholders. These major stakeholders will be able to communicate through smart contracts, which will act as a bridge between them. As part of their responsibility, they will make sure that all of the terms of the contract are met and acknowledged by all members of the team. As a result of our research, we propose a model in which payouts could be automatically enabled and penalties or grants could be introduced based on performance. If any changes were to be made to the contract in the future, all parties involved would be automatically notified. To maintain the development cycle, they should accept these changes as soon as possible. Because of this, the product owner and client are able to concentrate their resources on more profitable and productive tasks, without the need to monitor this aspect of agile project management. Our proposed model brings together different partners with the objective of successfully developing different IT projects by leveraging software engineering solutions such as smart contracts.
