The role and impact of computer and game addiction on education

Gábor Kovács — 2023-01-28

Computer games have many advantages and disadvantages in the field of education. While benefits include improving problem-solving skills, increasing motivation, and learning based on immediate feedback, disadvantages include ergonomic issues, health risks, and potential safety hazards. The use of games in education raises complex questions for both teachers and parents. While games can promote learning and the development of elementary school skills, their excessive use can increase addiction problems and negatively affect students' physical and mental health. The article discusses the educational benefits and development potential of computer games, the health and ergonomic risks, as well as the negative effects of overuse of games and security challenges, especially in online gaming communities.

Analysis of digital education in Hungary

Róbert Csikó — 2023-01-28

Vocational training in Hungary has to face specific challenges. Due to low social prestige and social disadvantages, enrollment in vocational training is selective, and the IT field is no exception. Improving government in order to raise the quality of vocational training, including the development of digital competences. However, the lack of digital education, the lack of digital training of teachers, the outdated school equipment and the low rate of IT education are still a problem. The further development of instructors is key to the implementation of successful digital education in vocational training.

Android table football application development

Tamas Mark Matuz — 2023-01-28

For quite a few years now, mobile devices have generated more data traffic than desktop devices, which is why I decided to create my own mobile application, which can be used by almost anyone with a phone based on the Android operating system. According to Google, 99% of devices can run within this layer. My goal is to create something unique, useful and new, that's why I decided to create an application related to sports, since it is usually included in people's daily lives. After a little study and research, I decided to make a foosball app, as there are very few similar apps on the market. With the application, I want to encourage young people, or simply people who want to play foosball, to get out of their homes and find the right table for them. After registration, users can already see nearby tables and their ratings with a few clicks. I created the client in Java, and the web application server in PHP. The application relies heavily on the Internet connection, so it cannot store or display data without it. The client communicates with the application server via the HTTP protocol, with JSON objects, as both languages support it. In any case, I set as a primary goal that the data should function and appear in the same way not only on modern devices, but also on older, outdated devices. That's why I set the minimum SDK as low as possible and the maximum as high as possible. My further goals to be achieved include the cleanness and simplicity of the user interface, so I used the official Material Design theme developed by Google. Also, app security was an important consideration for me. That's why I used reliable libraries and safe filters on both the client and server side.

Development of .NET software module for communication with PLC

Janos Orgovanyi — 2023-01-28

Today, large companies are striving for productivity, which is why in most places they already replace human resources with robots, since the robots work based on a specific program. As a result, they are less likely to produce scrap products than humans. Although we are still a long way from eliminating human intervention from factory areas, multinational companies are already striving for this. The topic of this article is the development of a software whose task is to communicate with automated systems and to control the system. Overall, automation is important for productivity, that is, for companies to strive for productivity. However, it must be taken into account that, in many ways, it is inappropriate to exclude human intervention from production. To some extent, the module I wrote also contributes to the displacement of the human factor, but at the same time it also requires the intervention of a user.

Operating modes of driverless material handling machines

This article describes the development and application of driverless transport vehicles, in particular AGVs (Automated Guided Vehicles). AGVs have expanded considerably over the years, initially as simple towing vehicles that followed wires on the floor, but now there are many different models and applications. AGVs range from industrial applications to warehouse and human service areas. AGVs are now used in almost every industry and, as technology continues to advance, we are seeing
them in more and more areas. Money invested in automation is one of the best investments for warehouses, and the proliferation of AGVs and AMRs (Automated Mobile Robots) reflects this trend.
