This article presents a theoretical analysis of the problem of comprehending educational material in mathematics on the example of a problem that was proposed by NN Pangina as a “touchstone” for studying the interaction of a teacher and a student in organizing the latter’s independent work (from ed.: Pangina’s article is published in this issue of the journal). The article discusses a methodological approach based on changing the pedagogical goal in relation to the task. Instead of starting with a search for a solution to the problem with specific data and focusing the student’s attention on “building a route” from the conditions of the problem to what needs to be found, it is proposed to build models that allow generating new problems similar to the one given. This formulation of the problem changes the psychological attitude of the student, relieves him of responsibility for the success of solving a specific problem. At the same time, prompted pushed by the teacher, the student builds various simulation models that can be easily programmed and turned into problem generators, thereby forming a mathematical model of the problem area in which the problem was set. The proposed approach is based on the activity approach proposed in the works of AN Leontiev in the 70s of the last century [1], the idea of bringing out difficult-to-understand intellectual actions outside in order to use the mechanism of internalization [1, 2] and the works of Simour Papert related to the use of computer artifacts as intermediaries for comprehending new mathematical ideas [3, 4].

Turbulent periods of transition from socialism to neoliberal capitalism, which have affected the relationships between holders of power and governing structures in Serbia, have left a lasting impact on the urban spaces of Belgrade’s cityscape. The typical assumption is that the transformation of the urban form in the post-socialist transition is induced by planning interventions which serve to legitimize these neoliberal aspirations. The methodological approach of this paper is broadly structured as a chronological case analysis at three levels: the identification of three basic periods of institutional change, historical analysis of the urban policies that permitted transformation of the subject area, and morphogenesis of the selected site alongside the Sava River in New Belgrade. Neoliberal aspirations are traced through the moments of destruction and moments of creation as locally specific manifestations of neoliberal mechanisms observable through the urban form. Comparison of all three levels of the study traces how planning and political decisions have affected strategic directions of development and, consequently, the dynamics and spatial logic of how new structures have invaded the street frontage. The paper demonstrates that planning interventions in the post-socialist transition period, guided by the neoliberal mechanisms, has had a profound impact on the super-block morphology.

The article examines the debate between, on the one hand, the proponents of the position that European reason and logic are universal and therefore the dialogue between West and East will always be unequal and, on the other hand, the advocates of a pluralistic approach, who defend the equality of parties in the dialogue as well as the independence of cultures and ways of thinking in different regions of the world. The author expands the agenda of the debate, appealing to the authors of the book Dialogue of Cultures in a Globalizing World. In addition, the author clarifies the concept of globalization, used by many participants in the discussion, and also formulates his own understanding of philosophy. The author considers philosophy, firstly, as a way of deconstructing reality that has ceased to respond to the challenges of time, secondly, as a process of the creation of schemes defining new reality and objects and, thirdly, as personal and professional methods for solving these problems. The article also discusses the condition of the comprehension of procedural phenomena. Thus, there is a methodological approach that makes possible, according to Kant, to grasp the essence of complex systemic phenomena. Therefore, the author examines a case in which C.G. Jung talks about one of his own child experiences. The author argues that the conditions of the comprehension of processuality are, on the one hand, the formation of a special integrity that is personality and, on the other hand, its actions, which make it possible to assemble the discrete states identified by the researcher into a single process. The personality is considered as the subject who, starting from ancient culture, aims for independent behavior, partially overcomes social and cultural dependence, begins to build his own world and himself in this world.

The article is devoted to the study of the relevance of anthropological issues in the beginning of twentieth century and socio-cultural background of the anthropological sciences. The specificity of the subject and method of anthropology as a science in general focused on the systematization of empirical material which was studied. In this context, the logic of the formation of cultural / social anthropology and its instrumental interest to the video productions of technical media is studied. Anthropology tried to form a scientific understanding of human world as a holistic phenomenon (combining theoretical generalizations based on empirical data), while cultural anthropology focused on the study of cultural diversity. Visual anthropology emerged as a crossing of the fields of cultural anthropology as an academic discipline and the field of application of technical optical media, and thus a new source of empirical material. The gradual accumulation of empirical material in the "field researches" of anthropologists allowed to significantly expand the subject area and optics of anthropological science. And also it allowed visual anthropology to go gradually beyond the instrumental function that was originally intended for it. Meanwhile, the text-centered view of ethnographic material led to the transform of the culture of indigenous peoples into the codes of Western civilization, and hence to its reduction. Any of the various authentic non-Western cultures fundamentally distinguishes them from the unification style of the modern culture. The accumulation of video production by ethnography has allowed not only to preserve the disappearing authentic cultures, but also to develop methods of systematization of visual material, as well as to understand the role of visual anthropology as an autonomous discipline of the humanities. The integration of two aspects of visual anthropology (the production and study of images) casts doubt the classical style of positivist science: in particular, on the one hand the status of the subject as an observer or a spectator, on the one hand, and the monopoly of text optics, on the other.

The paper focuses on a methodological approach to identifying software in special software for systems of critical applications. The approach relies on the analysis of the subject area associated with the functioning of such systems. The term ‘software bugs’ is local and depends on the system into which they are embedded. In this regard, the methodological approach to identifying software bugs is illustrated by an automated system for preparing data for aircraft flights. By software bugs, we mean malicious software that can affect the algorithms for the functioning of the system, disrupting the normal mode of its operation and causing significant damage to the goals of the system. To find where software bugs are likely to be embedded, we specified actions which consist in understanding the features of assessing the quality of each of the main elements of the system and the essence of software bugs, with account for the features of the automated data preparation system; describing the system and its specifics; determining the most likely place for embedding software bugs and conditions for their initialization.

The paper presents results of simulation of the bearing misalignment defect in a power turboset. The results are shown in the form of a set of journal and bush trajectories of all bearings in the turboset. The subject area of analysis was the vibrational effect of displacing two most vulnerable bearings in horizontal and vertical directions by a maximum permissible range calculated taking into account the permissible bearing vibration criterion. Relations were shown between the shape and dimensions of particular bearing trajectories on the one hand, and their location with respect to the misaligned bearing and direction of misalignment, on the other hand. It was indicated that the relative journal trajectories and absolute bush trajectories carry much more information about the dynamic state of the machine than vibration amplitudes measured by standard. The trajectories contain the information on the amplitudes of relative and absolute bearing vibrations in all directions, complemented by journal and bush trajectory shapes, indicating the way in which bearings are loaded. As a result trajectories can be a source of information on the position and direction of bearing displacements. The article indicates the potential of using trajectory patterns for diagnosing misalignment defects in rotating machines. Including a set of trajectories to the base of knowledge of a diagnostic system can extend its diagnostic abilities by including bearing misalignment defects, which are frequently recorded in these machines.

In this paper, the author presents the survey of syntactic-semantic, and, in relevant instances, also pragmatic-semantic characteristics of the dative case in the contemporary standard Serbian language. On the one hand, the existing, extensive descriptions of syntactic-semantic behavior of the dative case in large grammar books (cf. Danicic 1858; Stevanovic 1979) taking into account the time when they were written - by their methodological approach and manner of presentation belong to the history of grammatical description; and, by the corpus they described, they belong to the history of the standard Serbian language. On the other hand, unlike other cases in the Serbian language, the dative case has not been monographically described so far, but it has been extensively discussed only in the confrontative research of the Russian and the Serbian language (cf. Milinkovic 1988). Taking into account all these facts, this paper is the author's attempt to point out to the well known characteristics of the dative case, along with some new details, presented in a different manner than before, but systematically comprehensively, clearly and, at the same time, without the extensive description of details irrelevant for the whole system. The author distinguishes eleven basic types of the dative case in the contemporary standard Serbian language. These are: the subject dative, the predicative dative, the object directive dative (that is the dative as the indirect object [the second object] and the explicative dative as the complement and at the same time, as a broadly understood, object-goal [and the single object at the same time], the possesive dative, the spatial directive dative, the instrumental dative, the causative dative, the criterion dative, the concessive dative, the ethic dative, and the dative in the speech acts of oaths and praises.

In connection with the deepening globalization processes and the interaction of scientists from different countries, the linguistic terminology systems of modern Slavic languages in the second half of the XX and at the beginning of the XXI century have been enlarged with new special units, which causes quantitative and qualitative changes in their composition, interest in the problems of the origin, formation and dynamics of this terminology system. The purpose of the study is to establish the regularity of the terminological nomination of linguistic concepts in the Middle and Modern Polish periods (XVI century – 1939). Taking into account the internal and external linguistic factors that influenced the formation and functioning of linguistics terminology in the Polish language, the basic methods of term formation (semantic, morphological, syntactic) are analyzed, confirming, on the one hand, the connection with the common language, and on the other hand, the uniqueness and specificity of the subject linguistic terminology corpus. The consolidation of a special nomination in Polish linguistic terminology at different chronological sections took place in stages. The transition of special words from one category to another (preterms → quasi-terms → terms) displays a system of complex changes in the branched term system of the subject area of linguistics.

  Introduction: the purpose of this research is to analyze the relationships and growth trends of Industry 4.0 within the global universe of current literature on innovation, limited to the subject area of business, administration, and accounting by means of a bibliometric analysis. Method: Scopus is used as a database for the analysis of 513 documents for the period from 1998 to 2021. VOS viewer was used for processing Scopus database and elaboration of figures representing the relationships between samples.                Results: the number of documents is exponentially growing, starting with a trend in 2017 and increasing ever since. The most dynamic source is Technological Forecasting And Social Change. The author with most documents is Voight, K. L. with 10, and the most distinguished institution is the University of Johannesburg with 14 documents. The country with more documents is Italy, with 69. According to the database 69 % of the total documents are articles and 23,4 % are conference papers. The number of documents in the area of Business, Management and Accounting, with 513 documents, exceeds by far any other area, representing 42 % of all documents. The funding sponsor with more documents is the National Natural Science Foundations of China with 13 documents. Some of the most updated organizations are Department of Mechanical & Industrial Engineering, The center for digital labor markets. The country with more documents is United Kingdom with 50 documents and 584 citations, followed by United States with 1110 citations. United States has mainly bonds with China, Australia, United Kingdom, Germany and Italy. United Kingdom has mainly bonds with France, Italy, Germany and United States. China’s main relations are Australia, United States, Pakistan, Taiwan, Turkey, Brazil and South Korea. Italy’s main bonds are France, Spain, Brazil, Russian Federation, United Kingdom, Austria and Portugal. It could be determined that countries are mostly grouped in 6 clusters. Conclusion: Although there are not many publications yet, it can be inferred that the term industry 4.0 within the available literature of innovation will keep increasing exponentially over time reinforcing relations between authors, institutions and countries. Based on the current state of literature, the subject area of business, management, and accounting will keep on being the one that encompasses most of the available documents.
