Abstract Languages for special purposes have mainly been considered from the point of view that they are specialized, i.e. that they satisfy the terminological needs of expression of specialized groups. The purpose of this contribution is to demonstrate that specialized discourses such as university lectures may make specific use of ordinary language devices. An analysis of sections from German lectures in physics and mechanical engineering reveals that deictics play a special role in propositional  composition. The findings are relevant for the general principles of linguistic science and knowledge transfer as well as for teaching German as a first or second academic language.

Patient routing is a key tool for ensuring the availability and quality of cancer care, ensuring early detection of pathology and timely treatment. Mathematical and simulation modeling methods allow to predict the bottlenecks of patient flows and plan the optimal distribution of healthcare resources. Goal to optimize patients’ pathways for oncology care using the simulation modelling methods. Materials and methods Patient routing was presented in the logic of discrete events, the average resource utilization, the patient’s stay time were described, the bottlenecks of the system were determined. Simulation modeling methods were used to build the optimal organization of oncology care services in the region. Results The average waiting time at the pre-hospital stage was 10 days, the average hospitalization time for X-ray therapy was 24 bed days, the throughput of the X-ray therapy room was 6 patients per week, the average duration of the X-ray therapy session per patient was 10 minutes. With the help of simulation modeling methods, a multimodal system of oncodermatology care was created and put into practice, which allowed to reduce the patient’s waiting time for treatment to 0.7 days, increasing the throughput of the entire system.

The essence of the concept of "product competitiveness" is considered. The factors of competitiveness of products of machine-building enterprises on the international market are systematized. Based on the systematization of quantitative and qualitative methods of assessing the level of competitiveness, a step-by-step method for mechanical engineering enterprises is proposed. The state of the machine-building complex of Ukraine is considered. The dynamics of factors of international competitiveness of machine-building enterprises is analyzed: number of enterprises by machine-building branches; volume of sales and production of machine-building products; shares of mechanical engineering products in domestic exports; capital investments of enterprises in the fields of mechanical engineering. As a result of diagnosing the factors, a PEST-analysis of the domestic machine-building complex with the division of factors into political, economic, social and technological was carried out. It is established that machine-building enterprises of Ukraine have a low level of competitiveness in international markets due to a number of negative factors, the key of which are: insufficient demand in foreign markets, high dependence on fluctuations in resource prices (economic); imperfect legislation, the war in eastern Ukraine (political); technological and moral obsolescence of products and fixed assets, high energy consumption and low productivity, low costs of R&D (technological); lack or outflow of qualified manufacturers abroad, low wages, low motivation of job seekers to employment in the field of mechanical engineering (social). Measures to increase international competitiveness which are proposed include following: preferential lending; revival of basic and applied science; reforming the legal regulation of intellectual property; ensuring compliance of products with European technical regulations. Prospects for the development of domestic engineering: digitalization, development of robotics, technology of Industry 4.0, infrastructure of technology parks.

This article explains the need for the research in the field of engineering terminology, the process of teaching it in foreign languages, the comparative application of engineering terms in different languages and studying the development trends. Objective of the article is to describe the methodology of teaching mechanical engineering terminology on the basis of study research in the field of mechanical engineering as a complex of heavy equipment in industry that produces household appliances, as well as consumer electronics and products of defense importance. Methods of the investigation that enabled to: study and analyze mechanical engineering terms; develop methodology of teaching mechanical engineering terms; analyze selection and assessment criteria of case studies; analyze selection and assessment criteria of project-based teaching; organize pedagogical experiments and analyze their results. It is an integral part to investigate the sphere of machine-building and metalworking industries, the production of metal products, metal structures and the repair of machinery and equipment. Furthermore, the issues of teaching engineering terminology in order to form professional foreign language competence in technical students by means of using new pedagogical technologies are of high significance. Such as, typology of terms in the field of mechanical engineering, teaching terminology whereby case studies and projects, examples of case studies and study projects are given. It is also important to pay attention to the etymology and the sources of the formation of terms, their peculiarities and definitions in special contexts as a complex human speech and language activity. Results and discussion. The article discloses the processes of activating terminology for obtaining information, through cognitive activity. Research works in the field of mechanical engineering, the practical basis of teaching terms and its effectiveness are also analyzed. The terms, vocabulary related to the field of mechanical engineering, case studies and analysis of independent work assignments are taken into account in the organization and conducting the trainings defined in the pedagogical experiment. As a result of experimental research, it was proved by mathematical statistical methods that the efficiency was achieved by 15% in case studies and 17% in educational projects. It was found that the mean value of the scores in the experimental group was 17% higher than in the control group. Hence, the research conducted has proven to be effective. Conclusions. The difficulties that arise in the process of comparing terminological activities show not only the specificity of individual languages, but also the specific role of terms in the national language system. Comparing the terminology of the English and Uzbek languages in the field of mechanical engineering not only allows to determine the general and specific features of the terms of mechanical engineering in the two languages, but also provides an in-depth study of both terminological systems.

Production Routing

The aim was to create a mathematical model describing the development of a production (shop-to-shop) routing of mechanical engineering products based on a 3D model and allowing the cost of the final product to be reduced. The developed mathematical model was simulated based on 3D models designed in the Siemens NX system, which were subsequently imported into the *stp format and recognized by a designed module written in the Phyton programming language. The factors of the production environment affecting the formation of the production routing of mechanical engineering products were determined. A diagram of the algorithm for the “constructive element - technological operation - means of technological equipment (equipment-tool)” relationship was developed. Based on the results of testing the developed mathematical model, the use of neural networks as a tool for the implementation and automation of the work was found advantageous as compared to the standard scheme of work of a process engineer when developing a production routing of mechanical engineering products. These advantages include a decrease in the time for the development of a routing and the cost of the final product. The developed model has a practical limitation consisting in a rather complex geometry of some structural elements of a unit, which impedes the development of an algorithm for recognizing their structure. The use of a neural network prototype in automatic mode is advisable for relatively simple parts (including a flange, hole, chamfer and rounding). However, since the number of simple units from the recognition point of view amounts to about 40% among the nomenclature of manufactured units, the reduction in the development time of the technological process in comparison with the conventional approach comprises only 10–25% of the total time of technological preparation.
