Part 5: Smart Solutions for the Future ; International audience ; The number of information technology users increases as fast as new information technology develops. This paper aims to analyse Internet users older than 65 years and focusing on the Czech Republic, the Visegrad group (also referred to as V4) and the European Union. Elderly people use the Internet the least from all age groups. The partial aim of this paper is to analyse whether, since 2009, there has been a constant increase in Internet users in the elderly age group in the Czech Republic and also the EU. The second scientific issue deals with the confirmation that the number of Internet users in the 65+ age group is similar to the EU-28 and V4. The analysis showed that the number of 65+ users has been steadily increasing since 2009. In the Czech Republic only 28.4% elderly people used internet in 2015 and 26.7% in 2014. According to Eurostat methodology the Internet is used in the 65–74 years age group by 33% of users. More than one third (38%) of elderly aged 65–74 used the internet at least once a week in the EU-28.

The introduction of information technology into all aspects of our lives has brought forth qualitative and quantitative changes on such a large scale that this process has come to be known as the Fourth Industrial Revolution, or Industry 4.0. The aim of this paper is to fill in the gaps and provide an overview of studies dealing with Industry 4.0 from the business and economic perspectives. A scoping review is performed regarding business, microeconomic and macroeconomic economic problems. Four investigators performed a literature search of the Web of Science, Scopus, and Science Direct. The selected period spanned from 2014 to 2018, and the following keywords were used for the search: Industry 4.0, economics, economic development, production economics, and financial sector. A total of 2275 results were returned. In all, 67 full papers were screened. Results obtained from the relevant studies were, furthermore, divided into the following categories: work and skills development; economy growth and macroeconomic aspect; sustainability; intelligent manufacturing; policy; and change in business processes. Findings show that the aspects of work and skills development, smart technology adoption, intelligent manufacturing, and digitalization are very well described. The government and its policies usually play the role of a needed supportive element. Usually studies lack a coherent view of the topic in question and solve partial questions.
