Abstract. The lexicon related to mining and mineral processing is a special segment of the professional language. Both the mining activity itself, which experiences significant changes in the course of technological progress, and the language reflecting this development are in a state of constant transformation. This article is devoted to the study of the thematic corpus of the German mine hoisting vocabulary, which is a narrow segment of mining terminology, while remaining an integral part of it. The subject of the study are terminological units used in the scientific field of mine hoisting and selected as a result of practical translation activity from specialized technical documentation, technological descriptions and guides. The study aims to investigate thematic groups of the German mine hoisting lexicon by using the lexico-semantic field theory. Such a method of analysis has not been used for the investigated professional lexicon before. Thus, the relevance of the study is determined by the insufficient research of thematic corpus of terms functioning in the lexicon of mine hoisting. The study revealed relevant lexico-semantic groups, determined their place in the field structure and elucidated interrelations of the term system in the language.

Key words: professional language, mine hoisting vocabulary, term, terminology, lexico-semantic groups, lexico-semantic field, German.

Abstract. The paper presents a component model of the existential potential of a teacher’s professional development, implemented in the Educational complex “Point of the Future” (Irkutsk), which is a vivid example of an innovative educational environment that supports the existential nature of teachers’ professional development, where self-development acts as a value guideline for both teachers and students. The features of pedagogical work in an innovative educational organization are revealed: “versatility of activity”, “high uncertainty of conditions” and “redundancy of professional opportunities”. Examples of activities contributing to the disclosure of the existential potential of professional development of teachers in the private educational institution “Point of the Future” are given. The tasks of scientific and methodological support are defined as one of the key conditions for actualizing the existential potential of a teacher. The article will be useful for education professionals and heads of educational institutions.

Keywords: existential potential, existential fulfillment, professional identity, reflective culture, professional development of a teacher, innovative educational complex.

Abstract. The study considers the issue of linguocultural types as recognizable images of individuals whose specific verbal and non-verbal behavioral characteristics and value dimensions significantly impact the culture of a particular society.  The background of the research is the theory of linguocultural types proposed by V.I. Karasik. The paper brings into focus conceptual, figurative features and value dimensions of the professional linguocultural type columnist. Of particular concern in the study is the value component of the linguocultural type columnist. The author claims that the core value of the linguocultural type columnist is based on the conceptual properties ‘personality’, ‘individuality’, ‘character’ of the columnist. The linguistic personality of the columnist is viewed as a bearer of personal views, individual opinions and intellectual qualities. The findings of the study can be applied in courses on cultural linguistics, media discourse and pragmatics.

Key words: linguocultural type, linguistic personality, concept, column, columnist, value characteristics, media discourse.

Abstract. The optimization of air traffic service (ATS) route networks is an effective approach to improving the structure of airspace, increasing its capacity, and reducing air traffic congestion. This paper presents a mathematical model and a method for optimizing ATS route networks based on the A-star algorithm, applied to the area control center Ho Chi Minh (ACC HCM) airspace. The ACC HCM airspace (one of the two ACC airspaces in Vietnam) ranks among the leading airspaces in Southeast Asia in terms of both size and workload. The objective function of the model is to minimize the total length of each ATS route within the studied airspace by systematically addressing specific constraints and optimizing the spatial configuration of ATS routes to ensure the most efficient passage within the given parameters. The calculation results demonstrate the potential of the proposed approach in increasing the airspace capacity, reducing air traffic congestion and operating costs, while maintaining the required level of safety.

Keywords: mathematical model, A-star algorithm, optimization of the ATS route network, air traffic, ACC HCM airspace, minimization of the total length of ATS routes.

Abstract. The paper focuses on developing students’ pronunciation skills in conditions of distance learning in higher education. The authors analyze the specifics of online EFL lessons (their advantages and disadvantages), list the main mistakes in teaching pronunciation and suggest the ways for teachers to avoid making them. The authors applied several methods during their research, i.e. comparative historical analysis of the up-to-date approaches to teaching pronunciation in English Teaching Methodology, observation, learning experience and project-based learning method. Special attention in the paper is given to the most efficient forms of student work during an online lesson in the aspect of acquiring natural English pronunciation and to the right way for teachers to motivate students and organize their unguided pronunciation practice activities. The importance of fostering students’ pronunciation skills is proven along with the vital role of pronunciation aspect in students’ communicative competence. The aim of teaching pronunciation is established with the term «threshold level of pronunciation». The article also concentrates on specific stages of online listening exercises and on the importance of doing them in the right order. Several options of facilitating the process of acquiring pronunciation skills during distance learning are offered in the article, i.e. shadowing technique, scaffolding, project work and individually-oriented approach.

Keywords: threshold level of pronunciation, oral communicative competence, phonological competence, communicative approach, pronunciation skills, distance learning, listening, connected speech, scaffolding, shadowing, project work.

Abstract. The article considers borrowing as one of the ways to enrich the veterinary terminology system in the German language. The analysis of the factual material revealed that the borrowed terms in the term system under consideration, formed in the majority by hybridization, are derivatives, complex words or terminological phrases. It is revealed that among the derivational methods, the suffix method is the most productive. The formation of complex exogenous terms occurs as a result of hybridization according to three models: 1) the first component of a compound word is a word of German origin, the second component is a loanword, 2) the first component of a compound word is a loanword, the second is a word of German origin, 3) both components of a compound word are loanwords. The most productive confixes involved in the formation of veterinary terms are bakterie-, immun-, toxi-, dermo-, patho-, bio-, hämo-/häm-/hämato-, enzephalo-. Among the terms formed by the syntactic method of word formation, the most frequent are uncomplicated two-component phrases constructed according to the models: Adjektiv/Partizip II + Nomen im Nom or Nomen im Nom + Nomen im Gen. The formation of exogenous terms in the field of veterinary medicine occurs mainly with the help of morphological, morphological-syntactic, as well as syntactic methods of word formation.

Keywords: German veterinary terminological system, borrowings of Greek-Latin origin, term element, exogenous term, hybrid term, confix, morphological methods of word formation, word composition.

Abstract. The article analyses the modifications of the concept «limita» in the context of song discourse. To solve this problem, the method of analysis of dictionary definitions and inductive frame allocation, discursive and stylistic analysis, conceptual analysis, description of cognitive metaphor, and contextual interpretation were used. The study reveals the expansion of the concept through several key frames, including social, economic, emotional, historical and «migration» ones. Considering the given concept from different points of view, the frame analysis reveals its social, economic, emotional, historical and migration aspects. The analysis of the concept «limita» serves as an example of how song discourse can reflect and shape social stereotypes. The study shows that song discourse not only entertains, but also performs an important social function, contributing to the formation of public opinion and identity.

Keywords: concept, anti-concept, frame, song discourse, linguoculturology, cognitive linguistics, functions of discourse.

Abstract. Design process of highly efficient means of communication, surveillance and navigation using switch-mode amplifiers requires a revision of traditional approaches to the circuitry of radio transmitting devices. The parameters of the physical layer of ADS-B systems using VHF datalink mode 4 (VDL-4) theoretically allow the use of switch-mode amplifiers as part of their transmitters. Such an improvement plays a particularly important role in the context of integrating unmanned aerial vehicles (UAV) with limited energy reserves on board into the general airspace.

One of the important tasks in the design of such radio technical support for flights operating in the VHF range (primarily onboard, but also ground-based) is to determine approaches to control transistor switches of a power amplifier based on the criteria of efficiency, stability and the ability to provide different operation modes of the switch-mode amplifier. Requirements for the control device have been developed taking into account the standard for the physical layer of VHF datalink mode 4. A conclusion is given on the optimal solutions suitable for building a VDL-4 transmitter with a switch-mode power amplifier, opening up prospects for increasing the efficiency of more than 90%, compared to today’s not exceeding 46%.

Keywords: VDL-4, VHF mode 4, radio transmitter, switch-mode power amplifier, modes (D, DE, E), integrated circuit.
