In this study, we examined the use of non-fungible tokens in the field of events.Using a qualitative research approach based on interviews with event organisers and participants who have already used non-fungible tokens at events, we explored the added value that non-fungible tokens have brought to events.We found that the use of NFTs is still in its infancy, but their adoption is rapidly spreading.NFTs are being used at events in the form of tickets, collectible items and certificates of attendance.NFT tickets add value to both organisers and attendees by ensuring the authenticity of the ticket, enabling a transparent secondary market, and allowing the easy definition of additional benefits such as discounts or access to VIP areas.Yet, several challenges must be tackled before NFTs can be broadly integrated into the tourism sector.iv

Since the last third of the 20th century, schools have been losing their exclusive position of a place of acquiring education. However, education is much more beneficial for current, so called "knowledge society", if we are able to enforce it. Educational system in the Czech Republic (CZ) has undergone essential transformation during last 15 years; a significant decentralization has occurred in regional education. The current aim following the Strategy Europe 2020 is to improve results and motivation of pupils and students at all levels of the educational system; an accent is given also to development of education based on lifelong learning conception. The article is dealing with the problematics of teacher's prestige. The results show that one of possible reasons for lowering teachers' prestige may be their low remuneration. In this respect, could improve the current situation as well in financing schools according to number of students and hours taught since 2020. Another reason is lower respect of teachers by students and their parents. The state should actively solve the situation by implementing rules to protect the school and teachers from the negative behaviour of students. Personality of the teacher will remain an equally important aspect.
Bitcoin, first introduced in 2008, and other virtual currencies (litecoin, ripple, ethereum, dash, etc. – known as “altcoins”) are a phenomenon of the 21st century. When speaking about bitcoins, views on cryptocurrency-related risks and benefits vary significantly. However, in this article, we will not focus on bitcoin here to illustrate how virtual currencies work. The aim of this article is to show how the borrowed Anglicism bitcoin is used in the Czech and the French languages. The purpose of the theoretical framework is to clarify concepts of neologism, Anglicism and internationalism and propose relationships among the concepts in a study. In the practical section, using the word bitcoin, we show how the loanword is used in both languages and how its integration into the language is similar. The main result of the analysis is a list of derived and compound words from the word bitcoin in Czech and French. The article deals with derived and compound words from the point of view of their quantitative evaluation using Aranea web corpora. In this article, we have shown the possibilities of their derivatives and adaptation to the given system of the language.
Kriptovalute su digitalni novac utemeljen na kriptografiji i decentraliziranom sustavu. Postoje samo u elektroničkom obliku kao jedinstveni digitalni novčići ("tokeni"). Iza njih ne stoji autoritet države niti ih je moguće svojevoljno proizvesti. Rad se fokusira na značajkama, postavkama, razvoju i svim međuodnosima važnih ekonomskih faktora koji utječu na kriptovalute. U prvom poglavlju navedena su obilježja kriptovaluta. Drugo poglavlje daje primjere i govori o primjeni kriptovaluta u svakodnevnom životu. U trećem poglavlju je raspravljano o trenutnim i budućim regulacijama najmoćnijih zemalja svijeta (G20) , kao i njihovoj zajedničkoj suradnji u želji za jedinstvenim i standardiziranim pravilima, a sve u svrhu što kvalitetnijeg nadzora nad kriptovalutama kako bi se spriječile malverzacije i zaštitili potrošači. Četvrto poglavlje govori o inicijalnoj ponudi kovanica, a peto poglavlje je namijenjeno sigurnosti kriptovaluta. Cilj istraživanja je utvrditi koliko je studentska populacija upoznata i usmjerena prema novim oblicima digitalnog novca, koje značajke kriptovaluta smatraju pozitivnima, a koje negativnima i u kojoj su mjeri investirali ili su spremni investirati dio svojih ulaganja u kriptovalute i sl. Metode istraživanja korištene u radu su kompilacija na temelju proučavanja postojeće literature o temi rada, prikupljanje i analiza podataka vezanih uz kriptovalute, ponajprije podataka vezanih uz cijene i tržišnu kapitalizaciju, anketiranje studenata Ekonomskog fakulteta u Rijeci i metoda dedukcije putem koje su pokazane sve važne karakteristike i obilježja kriptovaluta. Na temelju provedene ankete u kojoj je sudjelovalo 90 studenata Ekonomskog fakulteta u Rijeci zaključak toga dijela istraživanja je da je mlada populacija dobro upoznata s kriptovalutama i njenim glavnim značajkama, ali i određenim nedostatkom informiranosti o tehnologiji (trećina studenata nije čula za pojam "blockchain") i nedovoljnoj odlučnosti oko investiranja i trgovanja u kriptovalute. Povrh toga, dokazan je i negativan utjecaj hakerskih napada i određenih kriminalnih radnji, kao i nestabilnost tržišne cijene na povjerenje studenata, ali i ukupne populacije vezane uz globalni financijski sustav u kriptovalute. Ishod istraživanja omogućio je da zaključimo kako su kriptovalute trenutno u ranoj fazi razvoja i nisu se dovoljno implementirale za široku primjenu u trgovini roba i usluga ili općenito kao sredstvo razmjene. Faktor koji je uključen u istraživanje kako bi opisao veličinu, odnosno obujam neke kriptovalute je tržišna kapitalizacija u dolarima. Temeljna ideja ovog rada je informirati čitatelja o pozitivnim i negativnim značajkama koje se se vežu uz kriptovalute. Na taj način čitatelji će biti bolje informirani i educirani o potencijalnom riziku ulaganja u kriptovalute, kao i većoj razini zaštite prilikom posjedovanja neke digitalne valute.
The paper addresses the development of higher education in the Czech Republic after 1989, with special emphasis on the relevant legislation, institutional settings, financing, & enrollment. Czech higher education has changed profoundly since 1989. Universities were granted almost full autonomy as early as in 1990. They have reformed their curricula, expanded programs in the humanities & social sciences, & eliminated political criteria from admissions policies, both for faculty & students. However, the structural changes were not as quick & profound as obtaining & mastering the freedom was. The most significant structural changes in the Czech tertiary educational system addressed in the paper are decentralization & diversification. With regard to financing, the authors argue that universities have remained dependent on the state to a high degree. Several attempts to expand multi-source financing by introducing cost-sharing features (tuition fees, loans, student allowances) failed. The reliance on the public budget led to a severe financial crisis in public universities. As far as enrollment is concerned, the authors demonstrate that, although the number of students rose by almost 60% between 1989 & 2001, the offer of educational opportunities was too low to meet the steeply rising demand for tertiary education. The chance of being admitted hovered around 50%. Owing to the combined effect of a drop in the size of the relevant age cohort & the growing proportion of students admitted to bachelor programs, the chance of enrollment started to increase in 2001. In spite of this recent change, the transition from secondary to tertiary education still remains the most critical moment in an educational career.
