The Dualism of Information Measurement Methods in Industrial Analytics Management
Authors: Chuprov Sergey
Published: December 2023

In the economic space of dizzying changes, the growth of the analytical arsenal of industrial management shows the need to develop theoretical and methodological tools to study the quantitative and qualitative features of the functioning of production systems. The impact of random factors gives rise to the uncertainty of the system’s behavior and use of the statistical concept to measure their disorder, while non-statistical measures to assess current states and the information embedded in them are less prominent in research and industrial management. The hypothesis about the dualism of both — probabilistic and deterministic — methods becomes relevant in the face of increasing dynamics and chaos in the activities of industrial enterprises. The purpose of the study was to develop a deterministic approach to a generalized assessment of the variety of its discrete states, contained in their sequence of non-statistical information, and to argue for the complementarity of the proposed approach to the classical entropy doctrine of the disorder of system states and control information in it. The research methodology is system analysis, thermodynamics, statistical physics, synergetics, control and information theories, and production management. The information and empirical basis of the study was data on workload of production structures of a machine-building enterprise that manufactures a wide range of products. The objects of research are industrial enterprises that perform certain technological operations. Scientific novelty lies in the synthesis of statistical and non-statistical approaches to measure the order of the states and the amount of information embedded in their sequence for production systems. The conducted research provides industrial management with the analytics of the functioning of production systems to improve the efficiency and stability of enterprises in a highly volatile business environment.

In modern conditions of digital transformation, the problem of the development of educational organizations becomes relevant. The trend determined by state policy for the science field and higher education, aimed at creating a training system that ensures the formation of digital competencies of citizens and personalization of education, determines the strategic directions for the development of educational organizations. The purpose of the research was to consider the most important areas of development of educational organizations, one of which is the development of digital services. Further use of digital services will increase the efficiency and speed of acquiring digital competencies not only by students, but also by scientists, academics, administrators and managers of an educational institution. The analysis identified conditions required for the transition to the management of educational organizations based on data. The study showed that in the long term educational institutions will be able to move to management according to the model of a digital university and further — a digital twin of the university. Thus, predictive and prescriptive analytics should become the basis for effective management decisions that will increase the competitiveness of educational organizations in the educational services market and create conditions for the development of the country's economy.
The Activity of Chinese Healers in Irkutsk at the Beginning of the Twentieth Century
Authors: Shalamov Vladimir
Published: December 2023

The study explored the professional activity of representatives of traditional Chinese medicine in Irkutsk in the early twentieth century. In the Russian Empire, traditional medicine of the Celestial Empire was not recognized, since its methods and means were not known to European science. The medical community saw the actions of Chinese doctors as quackery. They were associated with sorcerers, healers and shamans. To escape from the law, Chinese healers preferred to settle in the suburbs where the urban poor lived. Exotic healers attracted quite a lot of wealthy citizens to the representatives of the Celestial Empire. For many poor people, they were preferred because of the affordability of their services. Informal methods of communication, posting ads, as well as veiled advertising in periodicals were widely used to attract patients. Chinese doctors actively used pharmacotherapy for treatment, as well as acupuncture. At the same time, Russian doctors were outraged by the disregard for the rules of personal hygiene and sanitation. Patient reviews of doctors were contradictory. The informal nature of the activities of Chinese doctors, as well as their huge popularity, led to imitation by the criminal world. Sometimes the activities of such deceivers ended sadly, which led to litigation. After the February Revolution of 1917, Chinese doctors switched to a legal status. The excessively strict legislation of the Russian Empire led to the fact that it became impossible to distinguish Chinese doctors from various kinds of scammers. In the conditions of personnel shortage in Siberia, Chinese doctors could benefit in the medical field. To do this, it was necessary to formalize the process of recognition of education received in China and limit the scope of their activities to certain areas of medical practice. In addition, oblige them to comply with sanitary and hygienic standards. Such an approach attracted Chinese doctors to the Russian service. Thus, it would be possible to study the methods of Chinese medicine.

Authors: Zhou Qian , Yang Fan , Yang Liming , Tang Shiguang
Published: December 2023

A new thermosetting polyurethane modified asphalt (TPUA) pavement material was developed to solve the unbalanced performance of traditional bridge deck pavement materials. Compared with the conventional bridge deck pavement materials, this work comprehensively evaluates the pavement performance of the TPUA binder and its mixture. The results indicate that the TPUA binder gradually shows elastic material properties at high temperatures and has excellent deformation resistance. The low-temperature flexibility of the TPUA binder is much better than that of SBS asphalt and epoxy asphalt (EA) binders. The TPUA binder is a viscoelastic material at low temperatures, and its creep meets the Burgers constitutive model. Moreover, the TPUA binder also has excellent mechanical properties and flexibility. In addition, the TPUA mixture has excellent mechanical properties, high-temperature deformation resistance and moisture stability. Its crack resistance at room temperature and low temperature is much better than those of SBS asphalt and EA mixture. This work will help us continue the development and performance research of TPUA pavement materials.

Published: December 2023

INTRODUCTION: Early intervention is essential for proper foot growth in postural congenital clubfoot (PCC), but little is known about its contribution to this deformity when subjects are evaluated through telemonitoring. OBJECTIVE: This study aimed to monitor the foot’s flexibility of newborns diagnosed with PCC by telemonitoring them during the first months of life. METHODS: A longitudinal descriptive study was carried out with a full-term newborns group diagnosed with PCC in at least one limb, presenting a grade ≥ 0,5 on the Pirani score. Newborns with other malformations were excluded. They were assessed twice: before and 30 days after hospital discharge, and the foot flexibility classification by the Pirani score was provided. The telemonitoring occurred weekly between the assessments, and the parents were encouraged to mobilize their feet and maintain foot position using orthosis or taping. RESULTS: Thirteen newborns (eighteen feet) presenting PCC were included in this study; seven neonates discontinued the study due to absences from pre-scheduled evaluations, and six were telemonitored for 30 days. They were born at 39 weeks (± 1.18) and 3346.54 g (± 306.51). The majority of the newborns were female (69%), one was born vaginally, and eight (61%) had a family history of PCC. Pirani's score ranged from 1 to 3 in the initial assessment. After one month of telemonitoring, three feet progressed to 0, and four feet scored between 0.5 and 1. CONCLUSION: This study shows an important improvement in the foot’s flexibility of newborns diagnosed with PCC evaluated through telemonitoring. Telemonitoring may be an additional resource for assisting newborns with PCC.

Published: December 2023

Aedes aegypti chemical control remains an indispensable alternative to prevent dengue, Zika, and Chikungunya outbreaks. Havana City requires constant surveillance due to its bioecological characteristics favor the proliferation of mosquito vectors of these diseases, which constitutes a high risk to the health of its inhabitants. The goal of this study was to determine temephos resistance levels in the populations of Ae. aegypti from five municipalities of Havana. The susceptibility of the larvae was evaluated by bioassays described by the World Health Organization. Aedes aegypti populations evaluated showed high resistance to temephos, with values that oscillated for the FR50 between 26,8 and 82,5 and for the FR90 between 16,6 and 42,5 respectively. The National Control Program of Aedes aegypti in Cuba must promote insecticide rotation policies to avoid or prevent the evolution of temephos resistance in Havana. In addition, an evaluation of the Abate doses applied by the operators in the municipalities studied must be carried out, since this could be influencing resistance development due to operational factors.

Authors: Baptista João Pedro , Rivas-de-Roca Rubén , Gradim Anabela , Loureiro Marlene
Published: December 2023

The beginning of the war in Ukraine generated a wave of disinformation in Europe. Our research intends to cognise the reaction of disinformation agents to the outbreak of war, analysing publications checked by Iberian fact-checkers during the first ten days of the conflict. Specifically, we used Voyant Tools online software to perform a quantitative textual analysis, which allowed us to survey the most relevant topics, formats for spreading disinformation and media platforms. We also analysed the presence of political leaders, countries and military terminologies. Our findings indicate that video is the most common format to disseminate disinformation content, namely, to illustrate war scenarios. In addition, our research also showed that online video platforms, especially YouTube, are closer to terms that portray military actions. This may have implications for fostering a warmongering feeling. Finally, we found that the fake content checked was mostly favourable to Ukraine, which raises new poignant arguments for the contemporary debate about disinformation in war.

Authors: Blanco-Herrero David , Castillo-Abdul Bárbara , Rodríguez Luis Miguel Romero
Published: December 2023

This research examines the patterns followed by disinformation in Spain through the fact-checking activities of Maldita.es, the leading fact-checking organisation in Spain. We sought to answer three research questions: 1. What are the predominant topics of the hoaxes debunked by Maldita.es? 2. Who is responsible for the creation and dissemination of these hoaxes? and 3. In what formats and platforms are these hoaxes generally distributed? For this purpose, we conducted a quantitative content analysis of 729 hoaxes fact-checked in 2022 by Maldito Bulo. 40.7% of the debunked hoaxes were related to social issues, while 37.2% focused on political affairs. Regarding those responsible for the creation and dissemination, most of the hoaxes came from unidentified sources, although when the identity is known, the most frequent contributors are social media accounts, alternative and partisan pseudo-media and journalists. These results explore the general disinformation scenario in Spain, using fact-checking as an approximation and discussing its implications.

Published: December 2023

Rad se temelji na rezultatima empirijskog istraživanja provedenog na prigodnom uzorku od 215 ispitanika. Osnovni cilj rada je steći uvid u percepciju ispitanika o stvarnoj proračunskoj transparentnosti i otvorenosti u Gradu Dubrovniku, njihovoj informiranosti i interesu za proračunske teme, dosadašnjoj uključenosti ispitanika u donošenje odluka i kreiranje javnih politika na lokalnoj razini, uzrocima političke apstinencije te spremnosti uključivanja u projekt participativnog budžetiranja. Rezultati istraživanja pokazuju lošu uključenost ispitanika u donošenje odluka i kreiranje javnih politika na lokalnoj razini te je cilj bio otkriti uzroke i pronaći prijedloge za promjene. Uzroci su: nezainteresiranost, loša informiranost ispitanika, nedostatak vremena te osjećaj da ne mogu ništa promijeniti. Participativno budžetiranje je specifični inovativni demokratski proces koji izravno uključuje građane u odlučivanje o alokaciji dijela proračunskih sredstava. Pretpostavke za uspješnu uključenost građana su zainteresiranost i informiranost, za što je nužna transparentnost rada lokalne vlasti. Unatoč najvišoj vrijednosti Indeksa transparentnosti, rezultati istraživanja ukazuju na probleme u Gradu Dubrovniku.

Authors:   Faculty of Economics in Osijek, Štimac Helena , Bilandžić Tanasić Karla
Published: December 2023

Achieving synergy between market demands and knowledge, competencies, and skills offered by higher education is a great challenge and represents a responsibility that most commonly resides with educators. The aim of this paper is to investigate the gap between the offered competencies and skills provided to students after they complete their higher education and the demands of the labour market in the area of marketing. In order to define the features of the gap, qualitative research was conducted using the group interview method (focus group), after which the results showed that the competencies and skills offered on the higher education market correspond to a certain extent to the competencies and skills demanded on the labour market. However, it was determined that the gap existed, and it was necessary to reduce it. Further adaptations and changes in higher education are necessary, but it is all held back by slow development, administrative overload, and inertia, both in higher education institutions and among its stakeholders.

Authors:   Hrvatska narodna banka, Rebić Pave , Arčabić Vladimir
Published: December 2023

Uloga i važnost fiskalne politike značajno je porasla ulaskom Hrvatske u Europsku uniju i europodručje, čime se izgubio monetarni suverenitet. Cilj ovoga rada je analizirati utjecaj međunarodnih integracija i političko-ekonomskog okruženja na karakter i održivost fiskalne politike u Hrvatskoj. Analiza je provedena procjenom funkcije fiskalne reakcije. Rezultati istraživanja pokazuju da je fiskalna politika održiva isključivo u osnovnim modelima gdje se promatra reakcija primarnog proračunskog salda na promjene javnog duga i jaza BDP-a. Međutim, prošireni modeli koji kontroliraju međunarodne integracije i političko-ekonomsko okruženje sugeriraju da fiskalna politika nije održiva. Kontrolne varijable uključuju ulazak u Europsku uniju, proceduru prekomjernog deficita te razinu neizvjesnosti. Razdoblje članstva u Europskoj uniji povezano je s višim razinama primarnog proračunskog salda, jer su nositelji ekonomskih politika morali odgovornije upravljati javnim financijama. Globalna financijska kriza značajno je smanjila razinu primarnog proračunskog salda. Fiskalna politika bilježi kontracikličan karakter u svim modelima. Temeljni doprinos rada je dokaz o važnosti međunarodnih integracija i političko-ekonomskog okruženja na održivost fiskalne politike.
Specificity of Drawing of Blind Students. The Tree Diagram Representation as a Case Study
Authors: Niestorowicz Ewa Anna
Published: December 2023

Introduction: For centuries, drawing has been a creative form of human expression. The author shapes the image of the phenomenon according to his own sensory experience and imagination and the knowledge carried by the language and transmitted through culture. This article concerns the representation of real-world phenomena in drawings by individuals who are completely blind from birth. Research Aim: The research goal is encapsulated in the question: Do blind individuals go through a similar evolution in representing tree forms in their artistic development as sighted individuals? I am particularly interested in the following issues: What aesthetic characteristics (form and uniqueness of perspective) distinguish the drawings by blind students? Are the patterns of sighted individuals similar to those constructed by blind individuals? Do blind individuals present a distinct vision of the phenomenon based on their own imagination and sensory experiences? Method: The method of the research procedure involves the analysis of art works created in the process of the act of drawing. In order to gain knowledge about the created phenomenon, the interview method and participant observation during the creative act were used. The subject of analysis consists of convex drawings on microgrooved foil. The formal layer of the artwork in the drawings of trees by blind students will be subjected to analysis. The image components of the phenomenon will be analysed in relation to the typology of tree forms in the artistic creations of sighted children, as proposed by Stanisław Popek (1985). In analysing the graphical representations of the phenomenon, I will also refer to studies on the development of a child's artistic abilities presented by specialists such as S. Szuman (1990), V. Lowenfeld and W. Brittain (1977), R. Arnheim (1974/2004), S. Popek (2010) and M. Uberman (2019). Conclusion: Based on the analysis of drawings, it can be noted that the blind create the phenomenon of the tree in the following ways: a) according to the pattern of the sighted, b) also developing their own, individual patterns.

Non-Everyday School Life of Students in Grades 1–3 During the COVID-19 Pandemic. Children's Creation of Social Life in a Crisis Situation
Authors: Bałachowicz Józefa
Published: December 2023

Introduction: The crisis brought about by the COVID-19 pandemic has induced numerous changes in the living and developmental environment of children. They have had to recognize and interpret these changes and engage in various new activities to cope with the extraordinary challenges. Purpose of the study: The aim of this study was to describe and understand how early primary school students experienced changes in the crisis situation within their home environment and remote education, as well as how they adapted to these unusual conditions. Methodology: The research employed a qualitative approach rooted in the paradigms of social constructivism and symbolic interactionism. The primary research method used was focused group interviews (focus groups) conducted with groups of students from both first and third grades in schools in Warsaw. Results: The results indicate that children experienced social isolation as a strong, multidimensional pressure that triggered negative emotions, a sense of confinement, inaction, and emptiness. In response to remote learning at home, they developed new routines, constructed workspaces, asserted their privacy, and valued the nurturing functions of their homes. They perceived remote learning as lacking in personal relationships, agency, a sense of learning, tiring, and dull, which led to their passive participation. Consequently, they expressed resistance and creatively sought ways to endure the school time with their peers in the "virtual courtyard." Conclusions: Analysis of children's discourse unequivocally reflects a negative assessment of emergency online education. It led to the depersonalization of the child, a sense of invisibility, voicelessness, and passivity during lessons, as well as a lack of personal learning experiences. Children's reflections and needs should be taken into account in ensuring the effectiveness of digital learning strategies.

Authors: Kocoń Malwina Maria , Malik Natalia
Published: December 2023

Introduction: The life and multifaceted activity of Maria Grzegorzewska (1887–1967) are a valuable historical source. However, what is most invaluable in the work of the precursor of Polish special pedagogy is the timelessness of her ideas, the echoes of which still resound today. Research Aim: The article attempts to indicate the influence of Maria Grzegorzewska on the development of modern pedagogical science and practice. Evidence-based Facts: Not only the scientific, organizational and educational activities of Maria Grzegorzewska, concerning surdopedagogy, oligophrenopedagogy and pedeutology, but also her views, which have a timeless character, were brought closer. Summary: It has been shown that despite the passage of time, Maria Grzegorzewska’s pedeutological, deontological, and axiological concepts have not lost their relevance, because they are based on universal values that are the foundation of the teacher-educator’s work.

The method of forecasting vibrations is considered. The technique is based on the assumption that the vibration preparation process can be attributed to the processes developing in the blowup mode. The properties of the technique are demonstrated on the example of a retro forecast of vibrations that took place in Turkey on February 6 and 20, 2023. The results of testing the methodology confirmed the assumptions underlying it. Approbation of the methodology made it possible to predict the time of exacerbation of the seismic situation in the region of the globe, which is very remote from the control point of the initial seismic information for forecasting.

One of the most progressive technologies in foundry is die casting, where a significant part is formed by die casting of castings of a lower weight category. In the case of castings cast by pressure casting technology, one of the important quality indicators is the internal quality of the casting presented by internal defects. In addition to the alloy used, the shape of the mold and the filling chamber also affect casting defects. Casting parameters such as pressure and speed significantly affect the quality of the resulting casting. The resulting homogeneity of the castings is very important in terms of mechanical properties.

Authors: Khandvi Akash , Chauhan Akshar M , Dave Neeru D , Dave Darshan D
Published: December 2023

The pancreas has important endocrine and exocrine function and diseases of it causes significant morbidity and mortality. Diseases of the pancreas thus remain a continuing source of frustration in modern medicine. Clinical parameters have their limitations in diagnosing such lesions. Radiological evaluation also helps in diagnosing these lesions but to a certain extent. A good tumor marker is the answer to these problems. There are two tumor markers CA 242 and CA 19.9 which will not only help in early diagnosis of various pancreatic lesions, but also in differentiating them into neoplastic & non-neoplastic lesions.

100 patients of various pancreatic lesions were evaluated prospectively having USG confirmed pancreatic lesions, unexplained pancreatitis, pancreatic mass or pancreatic cystic lesion or worrisome clinical, imaging (CECT/USG) or laboratory findings.

Serum tumor marker CA 242 is more specific (100%) than CA 19.9(75%) and CA 19.9(71.9%) is more sensitive than CA 242(70.1%) in patients of various pancreatic lesions. While combined serum tumor marker CA 19.9 and CA 242 was more sensitive (70.5%) and specific (100%) than CA 19.9 and CA 242 alone.

For detection of various pancreatic lesions by serum tumor marker CA 19.9 and CA 242, the sensitivity, specificity and positive predictive value increases if markers are used in combination (serum tumor marker CA 19.9 and CA 242).

: Ovarian neoplasms are the fifth leading cause of cancer mortality among females worldwide. It is associated with poor survival due to late clinical presentation with most cases presenting at stage III or stage IV.

: The present study was undertaken to assess the histopathological spectrum of ovarian neoplasms according to the World Health Organization classification (2020) and to determine the frequency and age distribution of these neoplasms in a tertiary care hospital.

: This observational study was conducted over a period of 3 years (August 2016 to July 2019) in the Department of Pathology, Gandhi Medical College, Telangana, India. All ovarian neoplasm specimens were routinely processed and histopathological examination was done for each specimen.

: A total of 115 cases were included in the study out of which 97 (84.34%) cases were benign, 6 (5.22%) cases were borderline and 12 (10.44%) cases were malignant. Surface epithelial tumours were the most common, followed by germ cell tumours and sex cord-stromal tumours. The age group of 31-40 years showed the largest percentage of ovarian neoplasms.

: Ovaries are a common site for tumours. Most patients present at late stages due to non-specific symptoms. Ovarian neoplasms are associated with a variety of clinical and morphological features and hence a correct histopathological diagnosis is required to institute appropriate therapy.

Platelet function disorders are highly heterogeneous; those may be inherited/ acquired. Patients with these may have inadequate platelet count with impaired function, but may also have both. Early detection of platelet dysfunction also helps in better patient management and improve outcome.

Prospective study done in 50 cases, Patient’s details history of thrombocytopenia. Complete blood count with peripheral smear is done and various parameters are analysed with respect to the platelet count, PDW, P-LCR. On EDTA preserved blood sample four monoclonal antibodies CD41, CD42b, CD61 and CD62p are applied and analysed by flow cytometer.

In 50 thrombocytopenia cases out of which 06(12%) were immunological thrombocytopenia & 44 (88%) were non-immunological thrombocytopenia.

Here we are presenting a case of occurrence of PFT in bilateral elbows. Patient presented with gradually increasing in size and painless swellings for 7 years. Excision was done and on the basis of histopathological and immunohistochemical examination diagnosis of PFT was reached.
Category of directness in vocabulary and pragmatics
Authors:   Saratov State University, Dementyev Vadim V.
Published: December 2023

The article deals with the linguistic and speech category of directness, which is dialectically connected with its opposite – the category of indirectness. Realizations of the category of directness are considered: firstly, in language vocabulary and idiomatics; secondly, in speech communication; thirdly, in a more general sense of understanding the features of the system of language and speech. Two aspects of using the concept of directness to characterize linguistic and communicative-speech phenomena are considered. On the one hand, the use of the concept of directness for this purpose is due to the semantic structure of lexemes directly / direct / directness, their direct and figurative (metaphor, metonymy) meanings, relations with opposite concepts (various depending on the meaning of “directness”). On the other hand, this is due to the character of natural human language, which also dialectically combines “directness” (of communication, communicative meanings) and “indirectness” (inaccuracy, asymmetry, etc.). In theoretical linguistics, for several centuries, these features of the nature of language have repeatedly become the object of reflection – from different points of view, in different concepts, under different names, while so far much more attention has been paid to indirectness than directness, which is shown by a review of modern linguistic literature, dedicated to the relevant features and units of linguistic and communicative speech phenomena. The article analyzes the contexts representing the semantic and pragmatic polysemy of directness in speech communication: situations that are comprehended as such in artistic dialogues (author’s speeches) (“He / she said directly” / “Say directly”); the main speech intentions of the speakers in these situations are revealed – recognition, request, consent and refusal, prediction, statement, promise.
A stinging remark as a speech act
Authors:   National Research Lobachevsky State University of Nizhny Novgorod, Bushuyeva Lyudmila A.
Published: December 2023

The aim of the article is to look into the frame structure of the speech act KOLKOST’ (stinging remark) in the lexico-semantic system of the Russian language and Russian discourse. The combination of the frame theory and the theory of prototypes in the research helps to figure out the peculiarities of naming and the characteristics of the lexemes, taking into account the human aspect in the language. The research draws on the data from explanatory dictionaries of the Russian language, the dictionaries of synonyms, the dictionaries of concepts. The Russian National corpus is used as a source of the contemporary contexts. Taking into consideration the existing definitions of an act, the research suggests viewing a speech act as an act driven by a certain intention, always performed in the society, that leads to certain consequences and gets evaluation (positive or negative) from other people. The study shows that the conceptualization of the speech act “a stinging remark” is closely related to the linguo-cognitive frame model constituted by the following elements: an intention, action, subject, object, valuation, result. The article points out how the elements of this frame model are represented in the Russian language-system and discourse. Through the analysis of lexicographic and speech data, the paradigmatic and syntagmatic peculiarities of the words that represent the frame-model, the prototypical characteristics of the structural elements of the slots were figured out. These elements (slots) of the frame-model are interrelated and represent different aspects of the situation called KOLKOST’ (stinging remark) in Russian. The research shows that the frame-model of the speech act called KOLKOST’ (stinging remark) is a complex structure, a linguo-cognitive model which reflects the fragment of the world with all the relations between its elements.
Features of the formation of the lexis of positive moral-ethical evaluation in the Spanish language of the 13–15th centuries (based on the material of the Mediaeval Spanish adjective virtuoso)
Authors:   Saratov State University, Vanyushkina Olga I.
Published: December 2023

The article focuses on the features of the formation of the lexis of positive moral-ethical evaluation in the Spanish language of the 13–15th centuries. The research is based on the material of the Mediaeval Spanish adjective virtuoso (virtuous), which in the studied period belonged to the core lexis of positive moral-ethical evaluation. This is explained by the role the Church played in the life of the mediaeval society, in the formation of ethical norms and a particular system of values. This is confirmed by the fact that the subject of sin and virtue occupied a significant place in the analysed texts. Mediaeval Spanish written monuments of the 13–15th centuries both religious and secular in nature serve as the source of the research material. The written monuments are contained in the Corpus del español electronic corpus. The use of corpus data made it possible to study those lexico-semantic and thematic relations that were inherent in the lexeme virtuoso in the period in question. A significant part of the analysed contexts, the main purpose of which was to name and characterize Christian virtues, along with the virtuoso lexeme, contains chains of lexemes of positive moral-ethical evaluation, which were the names of certain virtues: santo, poderoso, vergonzoso, honesto, etc. Positive moral-ethical evaluation was especially clearly manifested when the lexeme entered into antonymic relations with adjectives denoting various sins and vices: malo, vicioso, malicioso, bravo, etc. Subsequently, the lexical meaning of the adjective virtuoso, characteristic of the above-mentioned contexts, becomes widespread outside the religious sphere, and over time it becomes the main meaning at the systemic level.
Types of function words in Lu Yiwei’s dictionary (to the question of grammar terminology)
Authors:   Irkutsk State University, Kiryukhina Lyubov V.
Published: December 2023

The article deals with the set of grammatical notions used by the author of 《语助》 “Yuzhu”, that is the first special monograph in Chinese linguistics dedicated to the description of function words. The study of works significant for the development of the linguistic knowledge is very important for historiographical and epistemological description of the formation of a certain tradition (in this case the Chinese one), since such works mark the stages of qualitative shifts in the structure of knowledge. In the course of the research three types of function words were singled out: 辞 ci, 声 sheng and 语助 yuzhu. The description of how these terminological units are used in the works preceding 《语助》 “Yuzhu” (such as 《礼记正义》 “Li ji zheng yi”, 《毛诗故训传》 “Mao Shi gu xun zhuan”, etc.) is given. Diachronic analysis shows a certain continuity of Lu Yiwei’s 卢以纬 interpretations: he does not offer his own variants of naming function words, but uses terms that were coined by the literary people and commentators in previous epochs. To illustrate different types of function words, excerpts from dictionary entries are given, they are translated into Russian by the author. It is emphasized that these units do not have such properties inherent for terms as definition, accuracy of meaning, single meaning and form stability, so it is impossible to consider such units as proper terms. It is concluded that the traditional stage of linguistic knowledge development in China is characterized by the formation of the system of grammatical notions, there was no consistently developed terminological apparatus in this period, the structure of the language was not viewed systematically.
