Emergence of the International Political Economy as a platform for a complex interface between economy and politics coincides with a strong momentum of the last phase of globalization. The interdependence is explained through the prism of three classical theories, liberalism-as a pro-globalist theory, mercantilism, and Marxism, both skeptical of globalization. Shrouded in numerous controversies globalization has indeed achieved limited results. Paradoxically, actors in the borderless, neoliberal world are exclusively driven by capital. Governments often allow transnational companies to dictate market developments with direct influence on employment, gross domestic product, and power distribution. The aim of this paper is to show whether the neoliberal order is on the wane, an order in which non-liberal measures such as trade protectionism and border closure are increasingly being resorted to pushing back the processes of world economy liberalization. The basic liberal, democratic pillars of equality and justice have collapsed before the interest-driven economy.

—In order to analyze the feasibility of implementing elements of new communication systems under an SDR approach, this work presents the prototyping of an OFDM communication link using the GNU Radio open source tool and low cost hardware interface with HackRF One and RTL-SDR. Preliminary results have shown promise, allowing the design and testing of digital communication systems in a practical way and taking into account the real condition of the channel and deficiencies of the front-end

Introduction/purpose: Molodtsov introduced the concept of soft sets as a new mathematical tool for dealing with problems containing uncertainties. In the literature, different kinds of operations of soft sets are defined and used in theory and applications. Methods: This study is based on the paper "A New Operation on Soft Sets: Extended Difference of Soft Sets" by Sezgin, Ahmad and Mehmood [Journal of New Theory 27 (2019) 33-42]. Results: In this paper, we define a new operation on soft sets, called extended symmetric difference and investigate its relationship between extended symmetric difference and restricted symmetric difference and some other operations of soft sets. Conclusion: The author believes that the obtained results represent a significant improvement of many known results in the existing literature.

In this paper, tiling a plane with equilateral semi-regular convex polygons is considered, and, that is, tiling with equilateral polygons of the same type. Tiling a plane with semi-regular polygons depends not only on the type of a semi-regular polygon, but also on its interior angles that join at a node. In relation to the interior angles, semi-regular equilateral polygons with the same or different interior angles can be joined in the nodes. Here, we shall first consider tiling a plane with semi-regular equilateral polygons with 2m-sides. The analysis is performed by determining the set of all integer solutions of the corresponding Diophantine equation in the form of , whereare the non-negative integers which are not equal to zero at the same time, and are the interior angles of a semi-regular equilateral polygon from the characteristic angle. It is shown that of all semi-regular equilateral polygons with 2m-sides, a plane can be tiled only with the semi-regular equilateral quadrilaterals and semi-regular equilateral hexagons. Then, the problem of tiling a plane with semi-regular equilateral quadrilaterals is analyzed in detail, and then the one with semi-regular equilateral hexagons. For these semi-regular polygons, all possible solutions of the corresponding Diophantine equations were analyzed and all nodes were determined, and then the problem for different values of characteristic elements was observed. For some of the observed cases of tiling a plane with these semi-regular polygons, some graphical presentations of tiling constructions are also given.

The influence of light and temperature stress conditions and oxygen availability on the chemical composition of Satureja montana and Lavandula angustifolia essential oils is reported. Photostability and thermal stability were evaluated by gas chromatography-mass spectrometry (GC‑MS) analysis, comparing composition before and after the applied regimes. In Satureja montana essential oil, the amount of thymol (13.0-11.9%) and carvacrol (10.3-9.4%) decreased at elevated temperature and in the presence of air, with a simultaneous increase of p-cymene (24.2‑26.2%) while in an inert atmosphere the composition remained the same as in fresh oil. Light caused a dehydrogenation of α-terpinene (2.1-0.9%) and γ-terpinene (5.6‑4.7%) to p-cymene (24.2-25.9%) and decrease of trans-caryophyllene (5.1-4.3%). In Lavandula angustifolia essential oil, compounds sensitive to elevated temperature and the presence of oxygen were cis‑ocimene (2.8-2.2%) and trans‑ocimene (2.6-2.0%), alloocimene (3.0-2.3%), trans‑caryophyllene (4.3-3.6%) and β-farnesene (1.7-1.2%). Irradiated samples showed a decrease in the content of cis-ocimene (2.8-1.9%), alloocimene (3.0‑2.0%), crypton (0.6-0.1%), cuminal (0.3-0.0%), trans‑caryophyllene (4.3-3.5%), β-farnesene (1.7-1.1%) and germacrene-D (0.5-0.1%) and an increase of trans-ocimene (2.6-3.5%), β-bourbonene (0.0-0.2%) and several unidentified peaks. Both oils showed an individual response to light and temperature stress. The absence of oxygen and light is the only storage regime under which the initial composition can be preserved.

The family is the basic cell of every society; in it the life of an individual rises, develops and disappears. Family relations are the basis of every social and state system. As a result, all state systems have been trying to keep family relations in peace for centuries. The death of a family member is one of the many factors that can disrupt family harmony, especially under the additional influence of property rights. Centuries ago, the issue of the testator's property was regulated by customary law, and then by legislation. The paper deals with the institute of bequest, as one of the forms of inheritance, with special reference to the types of bequests in the Republic of Serbia. For centuries, bequest has been the institutional of transferring the property and legal relations of the testator to the heirs. The will as we know it today in its form has its basis in Roman law, which had a great influence on the first European civil codes, the Civil Code and the Austrian Civil Code. These codes are still in use today, and their special significance is that they are a panda to all later adopted civil codes, ie to all later established civil legal bases. The Austrian Civil Code had a dominant influence on the settings of the regulation of civil law in the Republic of Serbia. Today, there are nine types of bequests. Each of them follows the life situations, circumstances and circumstances in which it arises.

Inheritance law is a set of legal norms that regulate the property and legal relations of the testator after his death. The fact of death has haunted all social communities for centuries. The loss of a family member affected community members (family) both emotionally and property-wise. After the death of the testator, his property and legal assets remain, the significance of which is reflected on the heirs as well as on third parties, but also on the state as a successor in case of absence of the heirs. The paper deals with the legal regulation of two legal institutes: the contract on lifetime support and the contract on assignment and distribution for life. The paper follows their legislation with reference to certain issues of practice, legal and ethical dilemmas, and in the very conclusion, in parallel with the legal analysis of these two institutes, which by all their characteristics are characterized as legal obligations. These two contracts are the rights of business that have been present in social systems for centuries, their existence and significance have been minimized, and only in modern times have their legal regulations been obtained. Guided by the fact that they are "new" legal institutes, as well as by the fact that the practice, especially during the 90s of the last century, indicated and showed that these first two institutes are suitable for abuse of legislation, the paper addressed the issues of who and when can be a contracting party. , what are the prejudices of the contract, as well as the circumstances when and why they can be null and void, disputed in court or terminated. Man was born manipulative and easy, and the law, and the law, the state and the entire legal system are there to channel it and sanction bad motives, in order to realize an orderly democratic social system, and thus preserve the family as the basic cell of society.

Violence against children is a dynamic, changing social phenomenon. Every society, regardless of the level of development of democracy, economic and political development, regardless of the level of protection of human rights, encounters violence against children on a daily basis. The first professional interests in violence against children were made between the two world wars, but the first active measures to oppose it appeared in the mid-sixties of the twentieth century, in the most developed countries. In the 21st century, the countries of the "third world" remain in a civilizational, cultural, value cocoon. No matter how impossible and imaginary it may seem, in some countries, violence against children is still denied as a social phenomenon and a deviation. The negation of violence does not stem from the circumstance that the child is not physically and mentally punished, but that this "punishment" is justified for the purpose of good upbringing, tradition and similar found excuses. For many years, this attitude has been held in many post-communist states, states that have been isolated for decades, either because of politics or because of religion. However, with the globalization of society, the inevitable opening of borders, but also under great assets whose affirmation of ordinary organizations, primarily at the global and then at the state level, the topic of "violence against children" slowly gained its epilogue. Today, in 2021, violence against children is an open topic in most communities. There are no more taboos. And no turning heads from violence. Of course, there are exceptions, but the world is full of rules with some exceptions. The paper deals with two aspects: global and national, specifically the Republic of Serbia. The paper deals with the definition of the concept of the child, types of violence, legal acts regulating the rights of the child, applied measures, but also proposals for measures and moves to take exceptions (those who deny the existence of violence against children, those who it doesn't matter…) be if not zeroed, and at least minimized.
