Abstract. The paper presents the results of a study of individual circadian rhythms and age influence on maintenance staff fatigue. Fatigue indicators were assessed using seven indicators for four types of shifts: day shift, night shift, daily shift, five-day work week. Changes in the values of maintenance staff fatigue indicators were analyzed for each type of work shift, depending on the type of individual circadian rhythms (larks, owls, pigeons) and depending on age (20-29, 30-39, 40-49 and 50-59 years old). The data obtained show that the age and individual circadian rhythms influence the civil aviation maintenance staff fatigue.

Keywords: individual circadian rhythms, fatigue, maintenance staff, human factor, questionnaires.

Abstract. The risk of release of non-conforming products may arise under the influence of various factors. The results of earlier studies showed that the most significant factors that reduce the quality of products include a decrease in the efficiency of equipment, the level of professional competence of performers, the reliability of partners and suppliers of raw materials, materials, components. This work is devoted to the development of a mechanism for choosing a reliable supplier.

Keywords: product safety and operability, categorization of controlled parameters, selection and evaluation of suppliers, cost reduction.

The peculiarities of the language of russian germans (a case study of fairy tales by N. Wacker)

DOI 10.51955/2312-1327_2023_3_213

Vera B. Merkuryeva

Abstract. In the article, using the examples from Nellie Wacker’s fairy tales, which were published by a Kazakh publishing house in 1995, when the author was already living in Cologne (Germany), the originality of the language of Russian Germans is demonstrated. The article represents a certain contribution to the development of linguopersonology. The bilingual author consciously, and sometimes unconsciously, includes examples from the field of grammar, vocabulary, semantics and stylistics in the texts of fairy tales. All of them arose as a result of the contact of the two languages: German and Russian, as well as the processes of interference, and the consequences of the influence of the Russian language on the German one. All examples are confirmed by native German speakers and are clear evidence of the artistic bilingualism of Russian Germans.

Keywords: language contacts, bilingualism, literary bilingualism, bilingual literary text, interfering influence, Russianisms, fairy tale.

Abstract. This article explores presentation peculiarities of R.O. Jakobson’s (1896-1982) biographical data on popular Internet sites that often serve as the main or most sought-after source of information on the history of Russian and foreign linguistics by young researchers in Russia. A narrative metacritical approach to the information presented on these platforms allows to visualize the extent to which prominent linguists’ images can be distorted, exemplified by one of the founders of the Moscow Linguistic Circle and the Prague School of Functional Linguistics. The main attention is paid in the article to the Prague period of R.O. Jakobson’s activity.

Keywords: history of linguistics, narrative method, metacritical approach, Roman Jakobson, network resources on linguistics

Modus categorization of erroneous cognitions in the english worldview

Abstract. The study discusses linguistic categorization of erroneous cognitions verbalized by linguistic units like mistake, make a mistake, error, blunder, make a blunder, gaffe, make a gaffe, wrong, get something wrong, make a wrongdoing, wrongness. Of central concern in the research is the issue of the modus (interpretative) character of the concept MISTAKE that serves as the conceptual basis of the modus category of erroneous cognitions. The paper highlights the issue that the concept MISTAKE as a conceptually complex knowledge structure activates two types of knowledge representation: the primary knowledge representation of the events in the physical world (Тelling him the truth)) and the secondary evaluative representation of the knowledge once verbalized (was a mistake).  The paper focuses on the interpretative function of negative evaluative interpretation that serves as the conceptual basis of the modus category of erroneous cognitions. The author comes to the conclusion that the modus category of erroneous cognitions serves to interpret the secondary representation of knowledge from the perspective of the negative evaluation conceptualized as ‘an action  that produces a result that is not intended.’ The modus function of the negative evaluative interpretation serves as the conceptual basis of the modus category of erroneous cognitions. The findings obtained may be helpful for further study of the processes of evaluative interpretation and evaluative categorization as an integral part of human cognition.  

Kew words: mistake, concept, interpretation, modus category, modus categorization, evaluative interpretation, categorical status

Abstract. The influence of wind gusts on the safety of aircraft flights is described. The impulse nature of wind gusts is substantiated. Experimental studies of wind gusts carried out with the help of a parametric recording device on an ultrasonic beam and an anemometer are analyzed, and it is shown that wind gusts have an impulsive nature, similar to atmospheric noise envelope emissions. The results of the analytical description of the probabilistic characteristics of atmospheric noise envelope emissions known from the literature are applied to wind gusts on the runway. Characteristics are given for the average duration of wind gusts, intervals between wind gusts and the average duration of intervals, the distribution of the duration of wind gusts, the average number and distribution of maxima of wind gusts.

Keywords: gusts of wind, probabilistic description, flight safety, aircraft, logarithmically normal model.

Abstract. The article discusses an approach to assessing the quality of the formation of competencies in the relevant disciplines mastered by a student or cadet of an educational institution of civil aviation. The assessment is formed by applying one of the unsupervised machine learning methods – hierarchical cluster analysis. Data collection to assess the cadets’ performance of a higher educational institution of civil aviation was carried out during the development of the discipline «Radio equipment of airfields». The experimental study took place during the semester. Tests for the discipline were formed in special Google forms, which made it possible to simplify the process of data collection and provide convenient control over the execution of tests. Data processing and further work with them was carried out in the Jupyter Notebook development environment using the high-level object-oriented programming language Python. In the program for the implementation of clustering, the cluster.hierarchy.linkage method from the SciPy library was used. For a graphical determination of the optimal number of clusters into which the sample should be divided, the Cattell’s scree criterion was used. The described approach makes it possible to single out students into separate groups (clusters) in order to automate the verification of the development of competencies.

Keywords: education, competencies, grade, statistics, machine learning, clustering, cluster analysis, dendrogram, automation, program.
