The development of mobile banking ensued after the development of the mobile phone market as well as the sudden emergence of the internet and electronic trade. In order for mobile banking to function properly, there needs to be a good collaboration between the banks and mobile phone companies, as well as a satisfactory software support for various services. Nowadays, almost all banks offer mobile banking to their customers. In the beginning, the clients had only the option of viewing their account information, while today they can complete transactions and do shopping. Mobile banking is seen as the newest means in e-banking, which will enable a suitable way of performing banking transactions by way of using the mobile phone or other mobile devices. The potential for e-banking can be a lot more feasible than by using the computer, because there are more mobile phone users than computer ones. In the beginning, clients were only able to have an insight into the balance of their accounts, and today they can perform many other transactions related to their payment cards, current and foreign currency accounts and loans. Mobile banking is the latest channel in electronic banking that will provide a convenient way to perform banking transactions using mobile phones or other mobile devices.

There has been an increase in interest in the Internet of Things (IoT) research endeavour. New concepts were discovered or existing ones were improved or fixed due to many novel research studies and IoT technologies in various sectors. There was also a focus on IoT security and standards for the Internet of Things. IoT applications that serve other industries, such as smart-living, industry 4.0, and e-health, are still relevant today. This paper aims to demonstrate that the Internet of Things (IoT) must be considered reliable, especially if it is data-driven IoT. Reliability of data-driven IoT is a complicated issue to solve because it involves hardware, software, people, and data, and today artificial intelligence. It is possible to calculate the reliability of an IoT system using a simple equation proposed in this paper. But the main problem is how to calculate the reliability of subsystems in this equation. Additionally, reliability is linked to availability and maintenance. The author of this paper primarily relies on two of his recent publications for the bulk of this paper’s content.

(I)Student access to Artificial Intelligence (AI) and Machine Learning (ML) platforms and powerful computers is only possible if educational institutions make these tools available. Students who do not have direct access to these technologies can still access this technology through university computer labs or studios.(M)The paper based on survey method addresses the research problem that students who are not aware of artificial intelligence (AI) and machine learning (ML) technologies, or have a rudimentary understanding, find it challenging to adopt AI-powered systems. Therefore, the research paper explores the awareness of AI&ML among students of chosen Higher education institution (HEI). (R)Exploratory research provided results that gives us insight in Hight education in Republic of Serbia, and state of mind of Serbian students. (D)The results show that students of chosen HEI are aware of these technologies and use them on a daily basis, indicating that they will easily adapt to AI-powered systems currently, during the development phase.

Modern information and communications technology (ICT) affects not only the digital transformation of business, but that of society in general. The impact of ICT on economic development has been recognised by the European Union through its Digital Decade strategy that highlights the development of a digital society by 2030, while the European Commission has launched the Digital Agenda for Europe, aimed at creating a unique digital market. In order to fully use the potential of ICT, the Government of the Republic of Serbia has adopted a series of strategies in the past few years with the end goal of improving employment opportunities and the quality of life. Using the publicly available data provided by the Statistical Office of the Republic of Serbia and the information provided by oecd.stat. at https://stats.oecd.org, this paper focuses on the development of a dimensional model for the analysis of information and communications technology use in Serbia and the comparison with data from EU countries.

Smallpox is a deadly disease caused by a virus from the group of orthopoxviruses. It is best characterised by a rash that appears 12 days after the infection. The virus spreads rapidly through aerosols and can lead to explosive epidemics with unforeseeable consequences. Smallpox has been widespread in the world for centuries, and about 30% of patients die from it. The largest outbreak of Smallpox (Variola vera) in Europe after World War II was that in the former Socialist Federal Republic of Yugoslavia (SFRY) in 1972. The death rate was 20%, i.e. 35 out of the 175 infected people died in a population of approximately 20,600,000. These numbers made the epidemic one of the most dramatic in the 20th century when it comes to public health in the Balkan region. Social and economic consequences were profound. In addition to disrupting social life (meaning that a lot of people were quarantined and had no chance to make contact with their families, which exposed them to stress and made them dissatisfied), the spread of smallpox in the SFRY had a significant impact on the country’s health and economy. A total of 6 billion SFRY dinars (about 600 million US dollars) was spent on the epidemic in 1972.

The book entitled Essential Discrete Mathematics for Computer Science by authors Harry Lewis and Rachel Zax, published by Princeton University Press in 2019, constitutes an important contribution to the study of the mathematical foundations of computer science. In addition to an introduction to discrete mathematics as a science, this 400-page book presents us with as many as thirty-one shorter chapters and a large number of exercises (more than 300). The importance of this book primarily stems from its good organisation, because each chapter of the book is suitable for one lecture, i.e. every chapter is a separate lesson with concluding analyses and problems suitable for homework or group exercises in class, so it is useful for both undergraduate and master studies in the field of mathematics in information technology. Because of its unique concept and simplicity of presentation, a large number of examples and proven formulas and theorems, the book is valuable to students and professionals who use discrete mathematics in the field of computer science.
