After COVID-19, new accreditation standards include the need for developing better learning and teaching environments. This will be supported and connected with digitization, entrepreneurship, social inclusion, and a circular economy. The orientation towards equity and quality in education clearly imposes the need for an individual approach to each student separately. This situation is especially pronounced in higher education institutions in the field of technology, whose primary goal is very often individual training for use of highly specialized software and hardware tools. In such a situation, it is necessary to move away from the classical ex-cathedra methodology and develop student-centered learning environments. Global accreditation systems for teaching, learning, practice, and business communication can be simplified using blockchain. On the basis of blockchain technology (BCTs), this paper proposes a Collaborative Learning and Student Work Evaluation (CLSW) model that includes a multi-frontal teaching method (VFN) and combines scientific peer-review standards. BCTs are used to protect student project and assessment data storage and transmission. Assisting higher education institutions in finding “employable capabilities” of proactive students is the idea of CLSW. Before implementing the CLSW paradigm, a poll of lecturers’ views on BCTs was conducted. The poll results show a desire and willingness to teach with BCTs. The model’s fundamental capabilities and the key participants’ duties were described in a project framework. Additionally, this research and proposed model can improve educational process sustainability in general, as it is an open platform easily accessible by all the interested parties, thus contributing to life-long learning.

Covid-19 initiated freight-forwarding, logisticians and customs officers to re-assess their strategy and realization of supply chains..

Srbija je tokom 2010.godine napravila veliki korak i iskoračila ka punoj integraciji svog ekonomskog i političkog sistema ka EU. Dobijanje saglasnosti za sporazum o stabilizaciji i pridruživanju, otvara mogućnost za pregovore i upitnik o sledećem koraku, dobijanju statusa kandidata za EU. Sam rad će detaljno opisati sva prava i obaveze koje Srbija po dobijanju statusa kandidata mora da ispuni, kao i prednosti sagledane kroz dostupnost fondovima EU koji zemljama kandidatima stoje na raspolaganju, kao i primere zemalja koje su ovaj proces završile i uz pomoć fondovima EU povećali svoj GDP. U samom radu prikazaće se i primeri zemalja u okruženju koji su bili na približno istom razvojnom nivou kao i Srbija, na samom početku integracije, kao i benefite koji se sada vide u prezentovanim zemljama.

Globalization and the changes that have affected the world economy conditioned the development of new models of thinking, investing, trading and payment methods in the world economy. End of XX and beginning of the XXI century was marked by rapid technological progress, which has not bypassed any economic sector, and all households have experienced the change. Cryptocurrencies represents a new model of trade and payments, but also a way for making some form of earnings. It is a form of property that is used as a digital asset exchange using cryptographic algorithms for "mining" new values, but also as a way of ensuring the security of transactions in a given syste. It's still early for assessments. The future might show what kind of impact would this kind of payment have, however, we believe that no cryptocurrencies will be recognized as a legitimate competitor in sovereign currencies.

The distribution of world wealth within certain countries, as well as the distribution of market shares of certain economies, has been significantly shaken and is changing significantly. As a result, globalization and the world economy that we have known so far, to some people’s regret or joy, are at the very end of their existence, and the market conditions and behavior of certain global powers will be significantly changed in the future and set in new economic conditions. Customs policy and the increase in customs rates in national customs tariffs, towards certain countries and their goods at the level of certain countries and the Union will shape the world economy in the short and medium term. The numerous customs and trade wars that have begun, which are currently taking place between the most important global nation states and the Union, will increasingly culminate in the future. There are no longer cheap energy sources as an input in production processes on the one hand, while a large diversification is increasingly evident in labor costs. National economies, insisting on financing the domestic economy through borrowing, are causing the production sector of goods and services to collapse, while housing construction and the increase in GDP based on this element are leading to an ever-increasing difference in international trade and a deficit in the foreign trade of the most developed countries. As a result, certain economies are trying to correct their imbalance in international trade with tariffs and high rates to improve their positions. In this paper, the authors will attempt to point out the negative effects that such moves can cause in the world economy.

The reindustrialization of the United States in recent years has been driven by a strategic combination of tariffs and targeted tax incentives. Tariff measures, particularly on steel, aluminum, and selected imported goods, aimed to protect domestic manufacturing from foreign competition and reduce trade deficits. Simultaneously, federal and state-level tax credits and subsidies—such as the Advanced Manufacturing Investment Credit, production-based incentives, and R&D tax benefits—have stimulated investment in high-tech and clean energy manufacturing. This dual approach seeks to revitalize domestic production, enhance technological innovation, and secure supply chains, while also presenting challenges such as potential trade tensions and increased production costs. Overall, these policies reflect a deliberate effort to strengthen the U.S. industrial base and foster long-term economic competitiveness.
