ОСОБЛИВОСТІ ОХОРОНИ ТА ЕКОЛОГІЧНОГО СТАНУ ЗЕМЕЛЬНИХ РЕСУРСІВ

The article discusses the issues related to the specifics of the protection and ecological condition of land resources and the determination of the most acceptable areas of land use protection in Ukraine. The purpose of the work is to study the issue of protection and ecological condition of land resources with the aim of more efficient and rational use and protection of land in Ukraine. The methodological tools of the research were: the method of analysis and synthesis; abstract logical method; method of analogy and generalization. The works of scientists related to the definition of the concept of land protection are analyzed. It was found that achieving positive results in the system of protection and ecological condition of land resources should be based on measures to ensure effective legal regulation of land protection in market conditions. Advantages of rational use, preservation of fertility and ecological state of land resources are highlighted. Land protection is a system of legal, organizational, economic and other measures aimed at the rational use of land, prevention of unjustified extraction of agricultural and forestry land, protection from harmful anthropogenic influence, reproduction and increase of soil fertility, increase of productivity of forestry land, provision of a special regime use of land for nature protection, health, recreational and historical and cultural purposes. Despite the technical and technological achievements of human society, at the beginning of the third millennium, the signs of energy, raw material, water, food, land and even air shortages are becoming increasingly apparent. The problems of ecological cleanliness of the natural environment, preservation of its reproductive, restorative and assimilative potentials are becoming particularly acute, as the volume of pollution, the extent of depletion and degradation of individual environmental resources are growing catastrophically. The population of our planet increases annually by 70–80 million people and is constantly armed with more and more powerful equipment and energy-dangerous technologies, exerting excessively large anthropogenic pressure on nature. Such actions lead to the deterioration of the environment by all indicators, which ultimately negatively affects human health and the quality of agricultural products.

ВИСОТНІ АРХІТЕКТУРНІ БУДІВЛІ В ІСТОРІЇ ЦИВІЛІЗАЦІЇ ТА ЇХ ЕКОНОМІЧНЕ ЗНАЧЕННЯ

The article examines the historical and economic prerequisites of the modern normative view on the relevance of the construction of high-rise buildings. In the conditions of martial law, the government is actively regulating and reforming the construction industry, which will form the normative basis for the restoration of our Motherland after the victory over the aggressor. From the time of the construction of the Egyptian pyramids to today, skyscrapers have been built in various parts of the world, including in Ukraine, but historically their permitted height was limited by the individual features of the laws of the countries (both technical, technological, and financial factors). The analysis of the historical experience of the relevance of the construction of high-rise buildings will provide an opportunity to determine the rationality of the implementation of investment projects of high-rise construction in Ukraine. The article examines the historical development of high-rise buildings in the history of civilization, their economic significance. The need to restore our Motherland after the victory over the aggressor requires the regulation of the construction industry, the creation of a regulatory framework for the implementation of investment projects in construction, including the construction of high-rise buildings, based on the historical experience of construction both in Ukraine and in other parts of the world. The question of the relevance of high-rise construction is quite debatable and individual from the point of view of the legislation of different countries. During the period of human existence, high-rise construction was implemented in different parts of the world, including in Ukraine, but the most skyscrapers were in China and the United Arab Emirates. Limitation of the construction of high-rise buildings until the 20th century. associated with limited technical achievements, as only ladders and models of water pumps were used for climbing to a height that made it possible to lift passengers up to a height of 10 m. At that time, buildings with a height of only 6 floors were erected. The activation of high-rise construction is directly related to the use of such innovations - elevators; pressure pumps that allow passengers to be lifted to a height of more than 10m and modern materials, mainly reinforced concrete and metal. The construction of skyscrapers during the period of industrial development and urban planning (1800s) was facilitated by American legislation, which included a significant increase in the value of land plots, the introduction of a tax on profits from the use of land plots. Unfortunately, today, due to the inhumane military actions of the aggressors, we will not determine the status of skyscrapers in Ukraine. But we are sure that after the victory in our Motherland, everything will be rebuilt.

Talking about moving machines

Abstract Globally, robots can be described as some sets of moving parts that are dedicated to a task while using their own energy. Yet, humans commonly qualify those machines as being intelligent, autonomous or being able to learn, know, feel, make decisions, etc. Is it merely a way of talking or does it mean that robots could eventually be more than a complex set of moving parts? On the one hand, the language of robotics allows multiple interpretations (leading sometimes to misreading or confusion in various contexts). On the other hand, the status of robots is challenged more and more by technical achievements and humans’ own empirical beliefs. In this paper, we follow a linguistic approach in order to explore the relevance of these words when talking about robots. Since we note that the words impose themselves (even if opposed), we discuss the efficiency of a rhetorical strategy in order to work with such a lexicon in robotics. More precisely, we explore the argumentative technique of the dissociation of notions through the study of a practical case: the case of robot lawn mowers versus hedgehogs.

Prospects for the development of the logistics system and its structural elements

The purpose of the study is to carry out a critical analysis of the elements of the logistics system of a modern enterprise, identify their functional characteristics and connections, and develop proposals for the stages of forming an improved model of the logistics system. The article highlights the issues related to the specifics of the formation of an effective logistics system of the enterprise by its constituent elements. It has been proven that the modern design of the logistics system should have not only traditional, but also innovative elements for high-quality performance of logistics functions. On the basis of the conducted analysis, the use of the graphic method and generalization, the relevant structural elements of the logistics system were identified. The role of the stimulating function of management in the matter of encouraging logistics workers to perform their duties in a high-quality manner is defined. In this context, the experience of Poland is given as an example. Comparing the salary level of employees at different levels of procurement and logistics departments, identifying the advantages of their functional powers and status made it possible to develop directions for improving internal and external relations to ensure mutual positive influence and achieve the effect of synergy. Taking this into account, a scheme of stages of the formation of an improved logistics system has been developed. Based on the results of the analysis, a conclusion was made regarding the expediency of using traditional and innovative logistics tools, as well as modern dominants associated with the use of technical achievements. The application of the author's proposals will make it possible to form a high-quality logistics system of a modern enterprise on a practical level. This will ultimately have a positive effect on the management of logistics processes and ensure better efficiency and effectiveness of the enterprise.

FOLK TRADITIONS AND CUSTOMS REFLECTED IN AN ELECTRONIC MUSIC TEXTBOOK FOR THE 7TH GRADE OF THE GENERAL EDUCATION SCHOOL IN BULGARIA

A person gets attached to things that are intrinsic to him, close, understandable and tends to reject what isunfamiliar and incomprehensible to him. The rapid technical development has brought not only enormous, but alsoconstantly accelerating change into our lives - ever greater and pleasant reliefs, which, however, increasinglydistance us from the traditional folk way of life, from the customs, holidays, beliefs, and rites of the people. We getsomething comfortable and irrevocable, but we lose something of our own, beautiful and also necessary - ourstarting point, our roots. Fortunately, this trend is being recognized by more and more people who are looking forways to counteract it without depriving ourselves of modern technical achievements. Since the knowledge of thetraditions, way of life, customs, and rites of our people are part of the culture forming the national self-awareness ofevery Bulgarian, such information should be studied. In the music textbooks for our general education school byProf. Penka Mincheva at al., the topic of Bulgarian is present from the 1st grade and continues throughout thecourse, with the study of folk customs, traditions and holidays. This topic is widely developed in the 7th gradeeducational set. In order to prove this, I will examine the materials included in the electronic textbook for the 7thgrade, which I am the author of and which is part of the educational set of the author's collective led by Prof. PenkaMincheva. In the electronic textbook, the information on the topic of Bulgarian traditions and customs is presentedthrough two photo galleries, it is also the basis of creative activities and various tasks. The taught material is richlyillustrated with pictures and sound examples. For the performance of these musical examples, which are onlyincluded in the electronic textbook, I selected young performers who have proven themselves at national andregional competitions - colleagues and students from the folklore specialties of the Academy of Music, Dance andFine Arts, where I work. The analysis of electronic resources (main method in the present study) on the topic ofBulgarian folk traditions - holidays, customs, rites and way of life highlighted the following results: - Electronicresources are closely related to the Electronic resources are diverse, thereby contributing to maintaining the interestof adolescents; - The electronic resources are compiled in such a way as to provide additional information; -Electronic resources are directly related to the creation of listening habits among students; - A significant part of theelectronic resources are organized as creative tasks, which is beneficial for the development of the creativity ofseventh graders; - Electronic resources are related to enriching the musical culture of young people; - Habits arecreated in seventh graders also for putting themselves in the other person's place, their empathic abilities aredeveloped. I am proud to share that the electronic materials of the Prosveta publishing house (Prosveta plus, whereour educational set is published, is one of the publishing brands of the Prosveta publishing house) have beenawarded the special prize for the best electronic aids of the BELMA (Best European Learning Materials Awards ) for2021. This is a serious recognition and at the same time authoritative proof of the effectiveness of Prof. Mincheva'ssystem of musical education and of our textbooks, including the electronic textbook for the 7th grade of secondaryschool.

Features of the international fragmentation of production in Boeing company

The level of development of the aviation industry is an indicator of the scientific and technical potential of any state and also affects its economic level. This industry practically cannot exist without interaction with other countries, as technical achievements, scientific discoveries, know-how of some countries help other countries to develop the aircraft industry, as well as bring it to a new level. Manufacturers of civil aircraft interact with a large number of suppliers around the world in order to create a quality product. Using the example of Boeing-industry leader, while studying the role of suppliers and the company’s supply chain, the peculiarities of fragmentation of this company and its positive impact not only on the company’s position in the market inside and outside the country, but also on the development of the entire industry as a whole are shown.

The Development of Forest Genetic Breeding and the Application of Genome Selection and CRISPR/Cas9 in Forest Breeding

With the birth of classical genetics, forest genetic breeding has laid a foundation in the formation of the basic theories of population genetics, quantitative genetics, cytogenetics, and molecular genetics. Driven by the rapid growth of social demand for wood and other forest products, modern genetics, biotechnology, biostatistics, crop and animal husbandry breeding theories, and technical achievements have been continuously introduced for innovation, thus forming a close combination of genetic basic research and breeding practice. Forest tree breeding research in the world has a history of more than 200 years. By the middle of the 20th century, the forest tree genetic breeding system was gradually formed. After entering the 21st century, the in-depth development stage of molecular design breeding was opened. With the continuous improvement of traditional genetic breeding methods, emerging modern bioengineering technology has also continuously promoted the development of forest genetic breeding. This study mainly summarizes the research history of forest tree genetics and breeding, as well as discusses the application of modern bioengineering technology represented by genome selection and gene editing in forest tree breeding, so as to provide better reference for forest tree breeding research.

Biojurisprudence is a fundamental part of modern general theoretical jurisprudence

It is indicated that today, addressing the problem of strengthening and maintaining public health in the context of global and social bioethics is due to an urgent need, since the phenomenon of public health acts as their natural embodiment and manifestation.Modern scientific research and innovative technologies in the field of biomedicine require intensive ethical regulation in order to preserve human health and life. Humanistic provision of clinica medicine, innovative and applied scientific research in the field of biomedicine and the formation of professional competences of specialists is connected both with scientific, technical and technological achievements in the field of biomedicine, and with a steady trend of their humanization and socialization,which requires addressing the phenomena of global and social bioethics, development of a system of ethical regulations of biomedical practice. It has been established that biojurisprudence is a fundamental part of modern general theoreticaljurisprudence. Biojurisprudence as a branch of legal science should study the complex of legal, medical, ethical and psychological components of human somatic rights, that is, all legal issues that arise as a result of a person’s exercise of the right to dispose of his own body. It is biojurisprudence that deals with theoretical problems in the field of law regarding as a whole, in turn, is the object of many non-legal sciences). Biojurisprudence should be considered as a complex, interdisciplinary scientific and legal formation, formed at the junction of bioethics, biolaw and biomedicine. At the same time, we believe thatthe development of biojurisprudence as a modern direction of legal science will contribute to the improvement of the culture of rule-making activity, the development and adoption of new effective normative legal acts that would take into account thelegal, medical, ethical and psychological components of the realization of somatic human rights.

Flood Risk Forecasting and Early Warning Technology for Medium and Small Rivers in the Yellow River Basin Induced by Heavy Rain

The Yellow River Basin is one of the important sand-producing and sediment-transporting areas in China, and one of the three most important sand-producing areas in the world. The amount of sand and dust days in the “Three Norths” (Dongbei, Xibei, and Huabei) area has increased, and regional sand and dust storms have occurred frequently. There are generally more serious hidden danger points of debris flow geological disasters in small and medium-sized river basins. The technical achievements of flood risk forecasting and early warning for medium and small rivers in the Yellow River Basin based on rainstorm-induced floods are important technical supports for flood forecasting and early warning for medium and small rivers. Based on this, a case study was carried out on the problems such as the weak forecasting and early warning ability of flood disasters induced by heavy rain and the low accuracy of flood disaster loss assessment in the flood disasters of medium and small rivers, for the reference of relevant personnel.

Multi‐stage superelastic variable stiffness pendulum isolation system for seismic response control of bridges under near‐fault earthquakes

To improve the resilient capability of bridges, a novel multi-stage superelastic variable stiffness pendulum isolator (SVSPI) is developed by incorporating superelastic shape memory alloy (SMA) with the multi-stage variable stiffness pendulum isolator (VSPI), which featured with the favorable adaptability under service conditions and near-fault excitations. Based on OpenSees platform, the numerical model for novel multi-stage superelastic variable stiffness pendulum isolator is created. A fractional factor based design method is suggested for parameter optimization of the multi-stage superelastic variable stiffness pendulum isolator. The example bridges with the novel isolators are designed to conduct the seismic mitigation investigation under near-fault earthquakes. The effectiveness of the novel superelastic multi-stage variable stiffness pendulum isolator and suggested design method is further discussed by case study. Results show that the novel multi-stage superelastic variable stiffness pendulum isolator designed by the proposed fractional factor based design method can perform the dual control of the isolator residual displacement, girder displacement, and base forces in piers for bridges. The effectiveness of the multi-stage superelastic variable stiffness pendulum isolator with the optimal parameters is demonstrated by case study.
