İnsanoğlunun tarih sahnesinde yer almaya başladığı ilk dönemden itibaren iktisadi faaliyetlerin normatif değerlendirmelerine dair tartışmalardan söz etmek mümkündür. Bu çerçevede iktisadi faaliyetlerle birlikte insanlığın farklı dönemlerinde faiz ve faizli uygulamalar olduğu bilinmektedir. Faiz sadece felsefi ve iktisadi çerçevede bir tartışma konusu değil ayrıca ilahi dinlerin de üzerinde durduğu önemli bir meseledir. Geçmişten günümüze faiz hem teknik hem de normatif yönüyle bireysel, toplumsal ve küresel boyutu açısından iktisadın en fazla tartışılan konuların başında gelmiştir. Farklı dönemlerde faiz yasakları veya faizle ilgili düzenlemeler/kısıtlamalar iktisadi yapı içerisinde yer almıştır. Faizle ilgili yasaklar tarihsel süreçte genellikle dini, sosyal ve felsefi temellere dayanmaktadır. Tarihin her döneminde gerek felsefi gerek dini referanslar temelinde faiz düşüncesine ve uygulamalarına kısıtlamalar ve yasaklar getirilmiş olduğunu ve günümüzde de bu tür tartışmaların devam ettiğini gözlemlemekteyiz. Çalışmanın amacı faiz kavramının yanı sıra tarihsel süreç içinde antik dönem uygarlıklarında, semavi dinlerde, Orta Çağ’dan günümüz ana akım iktisat literatürüne kadar faiz kavramının gelişiminin değerlendirilmesidir.

An experimental trial of nine rice genotypes was conducted in the Agronomy field of the Institute of Agriculture and Animal Science (IAAS) Paklihawa Campus under a randomized block design layout with three replications from July to November of 2022. The aim was to study genetic variability and analyze the character association of yield and yield-attributing components in rice genotypes and their direct and indirect effect on grain yield under reproductive drought stress conditions. Observations on days to flowering (50%), plant height, panicle length, panicle weight, number of grains/panicles, effective panicle/m², grain yield, and 1000 kernel weight were recorded. Grain yield showed a highly positive significant correlation with effective panicle/m² (0.713**), followed by plant height (0.347) and panicle length (0.289). The path coefficient analysis of different traits revealed the highest positive direct effect of the effective panicle per m² (0.748963), followed by panicle length (0.24145) and plant height (0.227505). The highest negative direct effect was shown by the number of grains per panicle (-0.31218). The experimental results revealed that the selection of trait-effective panicle per square meter would be most beneficial for the improvement of yield in rice genotypes facilitating selection and plant breeding programs.

An experiment was conducted to study the effect of municipal solid waste compost (MSWC) on growth, yield and protein content as well as to know the effect of combined application of MSWC and NPK fertilizers in rice (cv. BRRI dhan49). There were six treatments including- T0 = Control (No fertilizer or no MSWC); T1= 100% Recommended Doses of Fertilizers (RDF) NPK; T2 = (MSWC @ 5 t ha-1+ 75% RDF); T3= (MSWC @ 7. 5t ha-1+ 50% RDF); T4= (MSWC @ 10 t ha-1 + 25% RDF); T5 = (MSWC @ 10 t ha-1). The experiment was laid out in a randomized complete block design (RCBD) with three replications. Our results showed that the integrated application of MSWC and different RDF% had a significant impact on various plant growth and yield parameters including plant height, panicle length, number of effective tillers per hill, number of filled grains per panicle, 1000-grain weight (g), and grain and straw yield of rice. In case of T2 treatment, highest grain yield (5.70 t ha-1), straw yield (7.71 t ha-1) and protein content (5.875%) were obtained. Thus, the result indicated that combined application of MSWC with NPK performed better than the single application of either MSWC or NPK fertilizer.

This study was conducted in fourteen agricultural regions of Bangladesh namely-Mymensingh, Jashore, Cumilla, Bogura, Rajshahi, Sylhet, Dinajpur, Rangpur, Dhaka, Khulna, Chattagram, Rangamati, Barishal and Faridpur. The specific objectives of the present study were: i) to examine the determinants to adoption of rice mutant variety Binadhan-7; and ii) to identify the major preferences and constraints of rice mutant variety Binadhan-7 cultivation; A multistage stratified random sampling technique was used to collect the data. Marginal coefficients indicate that if male farmers increased by 100%, the probability of adopting Binadhan-7 variety would increase at 38 times more likely to adopt the variety. If the farm size of Binadhan-7 increased by 100%, the probability of adopting the variety would be increased by 0.07%. A farmer who has access to agricultural extension service is about 39 times more likely to adopt the variety. Again, if the yield increased by 100%, adopting the varieties would increase by 0.08%. The marginal coefficients of duration and soil fertility are negatively significant, indicating that if these two variables increased by 100%, the probability of adopting the varieties would decrease by 0.18% and 28%, respectively. Among the preferences, the highest preference was 88.93% for short duration followed by poverty reduction (88.57%), and lastly high yielding (81.43%). Among the constraints, the highest constraint was 80.71% for high labour price followed by lack of godown (69.64%), marketing problem (67.50%), destroy by bird (66.79%) and lack of quality seed (48.93%).

A field experiment was conducted at Grain Legumes Research Program (GLRP), Khajura, Banke, Nepal during spring and summer season 2019 to elucidate the effect of date of sowing and blackgram varieties on mungbean yellow mosaic disease severity and yield. The experiment was conducted in 2 factorial randomized complete block design with 3 replications. Factor A comprised date of sowing (S1= 5th April 2019, S2= 20th April 2019, S3= 5th May 2019, S4= 20th May 2019, S5= 25th July 2019, S6= 10th August 2019, S7= 25th August 2019 and S8= 10th September 2019) and factor B (Variety): V1= Khajura Mas 1 and V2= Rampur Mas. Disease severity was scored in 1-6 scale. Results revealed that mean values for days to disease appearance, disease score and grain yield in spring season sowing was 26 days, 3.72 and 635 kg/ha, whereas for summer season sowing was 14 days, 5.04 and 185 kg/ha.  Among the date of sowing, April 5th sown crop recorded minimum mean disease score (3.1) with highest yield (719 kg/ha). Whereas, September 10th sown crop recorded maximum mean disease score (5.1) with lowest yield (174 kg/ha). Black gram varieties showed significant response to mean disease score and yield at early sowing condition but when the sowing date was delayed, there was no significant response of varieties to mean disease score and yield. The contribution of regression (R2 =0.791) and (R2 = 0.655) for spring season and summer season indicate that 79% and 65% of the blackgram yield would be affected by disease for the respective season. Therefore, it is better to sow blackgram in early season to escape mungbean yellow mosaic disease and minimize yield loss.

Published: December 2022

The present study was conducted to assess job satisfaction of local extension agents for fisheries (from here and later in LEAFs) in Melandaha and Islampur sub-districts under Jamalpur district of Bangladesh. Data were collected by the researchers from LEAFs during September to November 2021 through face-to-face interviews by using a structured interview schedule. Descriptive statistics, rank order, and coefficient of correlation were used to analyze the data. Almost all of LEAFs (97.8 percent) had low to medium job satisfaction in extension service delivery. Among fifteen job satisfaction indicators, ‘supervisor’s guidance’ was identified as the most important one. The least ranked indicator was ‘job security’. Correlation analysis showed that age, level of education, job experience, training exposure, and organizational participation of LEAFs are significantly associated with their job satisfaction. All of the LEAFs (100 percent) faced medium to high problems in the research area. The most severe of the fourteen problems was ‘farmers’ reluctance to accept new technologies,’ followed by ‘shortage of manpower’. The least important problem of LEAFs was ‘farmers are non–cooperative’. Therefore, it is highly recommended that if an advance training program for LEAFs could be organized to solve their problems, it would be great to get quality extension services and build a well-organized fisheries sector in Bangladesh which will finally help to enhance nutritional security and poverty reduction in the country.

Customers prefer tilapia (Oreochromis niloticus), one of the most popular freshwater fish species farmed in Bangladesh, because of its flavor and affordable market pricing. This study aimed to develop value-added tilapia fish sticks and evaluate the quality changes, shelf life, and storage stability of the developed tilapia fish sticks in order to investigate the possibilities of better utilizing low-value tilapia fish and to satisfy consumers' growing demand for quality ready-to-eat food products. For this regard, storage characteristics in room (28ºC) and refrigerator (5ºC) temperatures were assessed in terms of microbiological, chemical, proximate, and sensory attributes. The moisture, lipid, protein, and ash contents of the fish sticks were observed to be 56.23±0.62, 7.62±0.27, 26.01±0.39, and 2.93±0.23%, respectively, at fresh condition. As storage time increased, it was discovered that ash content at room temperature increased while moisture, lipid, and protein levels steadily declined. On the other hand, it was discovered that at refrigeration temperatures, ash and fat content increased while moisture and protein content decreased. Compared to fish sticks held at ambient temperature, changes in the proximate composition of fish sticks stored in a refrigerator were found to be more stable. TVB-N was initially measured as 12.38±0.45 mg/100 g. After 24 hours of room storage, the TVB-N value exceeded the acceptable level; however, after 72 hours of refrigeration, it did not exceed the acceptable limit and was deemed fit for consumption. TPC was observed in fresh fish sticks as 3.74±0.31 Log CFU/g. In 48 hours at room temperature, the bacterial load of tilapia fish sticks increased sharply (p<0.05) during the course of the storage period and went above the microbiological threshold for fishery products (7 Log CFU/g of flesh). The bacterial growth trend was slower and, after 72 hours, was within the permitted limit at refrigerated storage temperature. All fresh products had the highest initial sensory ratings. At ambient temperature, all of the products sensory qualities significantly declined with time (p<0.05), however at refrigeration temperature, the product was determined to be more stable. The overall acceptability score assessed for appearance, flavor, taste, and texture was within acceptable limits for up to 24 hours at room temperature, but not for 72 hours at refrigeration temperature. According to the study's findings, tilapia fish sticks have a very limited shelf life at room temperature (28°C), only lasting around 24 hours, whereas they can last up to 72 hours at 5°C in the refrigerator.

Published: December 2022

A novel enantioselective adsorbent was obtained by hybridization of microspherical polystyrene-divinylbenzene (PS-DVB) macroporous particles with eremomycin-stabilized gold nanoparticles (GNPs). Macrocyclic antibiotic eremomycin was used as a stabilization agent to obtain GNPs which were then characterized by transmission electron microscope. The average diameter of obtained nanoparticles is about 16.6 nm. Eremomycin-stabilized nanoparticles were successfully embedded into the porous polymer structure with a resulting chiral selector content of 37.5 pmol/g. The obtained PS-DVB composite containing GNPs with immobilized eremomycin was studied by scanning electron microscopy and diffuse reflectance spectroscopy. The values of the specific surface area (500 m2/g) and porosity of the adsorbent (0.39 cm3/g) are measured using nitrogen adsorption at low temperatures. The obtained composite material was used as a chiral stationary phase of liquid chromatography. A good separation enantio-selectivity to amino acids, their derivatives and beta-blockers under RPC (reversed-phase) and HILIC (Hidrophilic Interaction Liquid Chromatography) mode is demonstrated. The results obtained revealed that the prepared Eremo@GNP@PS-DVB composite is promising for use as a stationary phase in HPLC.

Published: December 2022

Pharmaceuticals containing steroid hormones and their synthetic analogues are widely used in medicine. Accurate determination of the hormone content in biomedical objects is an urgent problem in modem analytical chemistry. A method for the selective and highly sensitive amperometric determination of adrenaline, melatonin, and cortisol in a flow-injection system has been developed. A scheme of a two-detector flow-injection system was proposed for the simultaneous determination of the adrenaline, melatonin, and cortisol content. Screen-printed carbon electrodes (SPE) with one or two working electrodes modified by gold-palladium binary system, which exhibited catalytic activity upon electrooxidation of organic compounds under study were used as detectors. A high sensitivity of the determination is attributed to the catalytic properties of the metal modifier: the transition between the metal and binary system leads to an increase in the catalytic current of hormones oxidation. The selectivity of the adrenaline determination in the presence of melatonin and cortisol is provided by the difference in the potentials of hormone oxidation at the developed electrode. For the selective determination of melatonin and cortisol the surface of the working electrode was modified by the Nation film. The potential difference between the oxidation peaks of adrenaline, melatonin and cortisol on the modified electrode was 300 mV. The proposed method was tested in analysis of real urine samples. The flow-injection scheme was supplemented with a dialyzer and a chromatographic mini-column to eliminate the interfering effect of electrophilic compounds. The linear logarithmic dependence of the analytical signal on the concentration of adrenaline, melatonin and cortisol is observed in the range from 5.0 x 10-10 to 5.0 x 10-3 M, from 5.0 x 10-11 to 5.0 x 10-3 M, and from 5.0 x 10-12 to 5.0 x 10-3 M, respectively. Amperometric determination of hormones in a flow-injection system leads to an increase in the productivity of analysis, decrease in the sample consumption and provides for automation of the process.
Results of tests for abrasive wear on a VIM LTDS installation
Authors: Rozhkov Yu. N. , Aulov V. E.
Published: December 2022

A number of well-known methods of accelerated testing for relative wear resistance are considered including a procedure based on the Brinell-Howarth method for laboratory studies and implemented on a IM-01 facility (designed at WISHOM) in which a powder abrasive is used. The shortcomings of those methods are discussed. A new VIM LTDP installation is developed in which an abrasive tape (320 mm and 15 mm in length and width, respectively) with a grain size of P60 is used as an abrasive material. The degree of wear was determined by a decrease of the sample mass using weighing on a balance before and after testing with an accuracy of 0.0001 g. The test results were obtained as a relative wear resistance e equal to the ratio of the values of the wear resistance of the test and standard samples. Consideration of the relative wear resistance makes it possible to increase the accuracy of the results due to the exclusion of the effect of changes in external parameters which determine the wear rate during testing. The installation ensures accelerated testing of the samples, i.e., the time for testing one sample is about 5 min. The structure and the grain size of the working body, the load value in the contact zone and the speed of interaction between the sample and tool are preserved. The use of an abrasive tape with different grain size provides for application of the unit to a wide range of tasks using samples without any preliminary grinding, but with the obligatory preliminary cleaning of the samples from slags and large particles after application of wear-resistant coatings.

The COVID-19 pandemic has forced educational institutions globally to resort to the online mode of teaching and learning. In this paper, we examined how the emergency online education was carried out in the Assam state of India. An explanatory mixed methods study methodology was adopted. Perspectives of 92 students and 30 teachers from 30 secondary level institutions of Assam were examined. Students’ acceptability of the emergency online education as well as the effects on the mental and physical health of the students were studied. Moreover, the teachers’ perspectives on the emerging online threats were also examined. Data were collected using two separate questionnaires administered to the students and the teachers. It was followed with telephonic interviews with the teachers to gain in-depth knowledge on the studied issues. This study examines both the positive and negative effects of the adoption of online education. The results indicated that all the students could not avail the benefits of this mode. Social messaging apps and online tools like WhatsApp, schools’ own mobile apps, Google Classroom LMS and Google Meet, ZOOM, recorded videos and audio tutorials were used to provide online support to the students. Impact on the physical and mental health of the students was observed. The online teaching process led to the generation of a large repository of e-resources. The results also indicated the ignorance of teachers regarding the online threats which could severely affect their students. The study recommended awareness programmes and training sessions for teachers and students on educational technology tools, technologies and approaches for the post-COVID-19 period.

All participants in the educational process adapt their lifestyle, workplace, communication methods and leisure forms to the new circumstances. Nowadays the consequences of this phenomenon begin to be studied. This article is devoted to the study of the experience of learning, communication and leisure of teenagers in conditions of social isolation and school closure and approbation of the risk and protective factors model in the context of adaptation to the distance learning. Thematic analysis of semi-structured interviews with adolescents aged 13-17 from Moscow, Ryazan, Tomsk, Moscow and Sverdlovsk regions allows us to characterize five thematic categories in terms of the main factors that make it more difficult or easier for schoolchildren to adapt to the distance learning. The categories include: school and teacher relations; supplementary education and hobbies; relationships with peers; family context; individual and personal characteristics of schoolchildren. The pilot nature of this study and a small sample limit the possibilities of extrapolating the conclusions to all groups of Russian schoolchildren, but allow us to problematize the complex nature of the difficulties faced by adolescents and demonstrate a wide range of resources that allow them to cope with them. Based on the results, we developed short recommendations that can be used by the management of educational organizations, teachers, and parents to reduce stress and simplify the adaptation of students during distance learning.

Relevance of the problem. The study of well-being in education is an important area of scientific research and practical interventions. WHO declare the human right to well-being. The aspect of the students’ well-being was added to the OECD PISA profiles and in the UN Sustainable Development Goals in the Edu2030, which confirm the significance of this theme (UNESCO, 2016). The key role of teacher well-being for the well-being of students and the educational environment in whole has become the focus of scientific publications, in particular confirming the significant relationship between school safety and teacher well-being (Sürücü Atila, & Ünal, 2015). However, teachers’ well-being remains low, which is revealed in the problem of the mass dismissal of teachers from schools. This problem is especially relevant among young teachers (OECD, 2020). This situation leads to a social contradiction that updates the study of the problem of teachers' well-being in the context of socio-professional conditions and the ethics of the profession. Current research of well-being is focused on an ecological approach as relevant to the modern requirements of science (Mercer, 2021). Thus, the purpose of this study is to define the concept of “subjective well-being of a teacher” and develop a model of the subjective well-being of a teacher in the context of the safety of educational environment using relevant scientific and methodological tools. Research methods: search and confirmatory factor analysis, comparative, correlation analysis. Technique: WHOQOL-100 Questionnaire, B. Tuckman Procrastination Scale”, Melbourne Decision Inventory, AVEM Questionnaire. The study sample consisted of N=600 teachers of secondary schools of the Republic of Tatarstan, noted by the type of settlement and their socio-economic zone. Research results. A model of the teacher’s subjective well-being has been developed in the context of the ethics of the profession “The triangle of professional well-being of a teacher”, which includes ownership, professional aspirations and quality of life as system-forming peaks. Practical significance. The results of the study can be applied for the educational programs for teachers’ training and retraining, for the supervising and psychological and pedagogical support of a teacher as well as to ensure the psychological safety of the learning environment of the school.

In this study, the tests of statistical hypotheses with crisp data using small samples are extended to with the membership function and the non-membership function of the intuitionistic fuzzy set. The test procedure of statistical hypotheses for means of two normally distributed populations with respect to any intuitionistic fuzzy set is proposed.
Intellectuals-enlighteners in the prose of O. Konyskyi and B. Grinchenko: the problem of their realization
Authors: Boiko Nadiia
Published: December 2022

The article deals with the prose works by two representatives of Ukrainian literature from the last quarter of the 19th century — Oleksandr Konyskyi and Borys Grinchenko. It emphasizes that a number of their works expand the genre-style possibilities of Ukrainian prose of their time, while simultaneously embodying their efforts within the limits of realistic artistic prose to model the desired idea of society. Aware of the limitations of their practical actions, the novelists count on the literature role of a serious mediator for the established communication between the “old” and “young” intellectuals, between the intellectuals and the people. The ideological prose was a way to promote Ukrainian culture and attract new forces to the cultural-enlightenment movement. The subject of research is the problematic-ideological basis of the works and their system of images. The object of research is the prose works by O. Konyskyi and B. Grinchenko, where the driving force of the plot and the main protagonists are representatives of various Ukrainian intellectuals, who used to be called "new people". The aim of the article is to trace the examples of these two authors’ works and how the ideas of the national movement and mood were changing among the Ukrainian public and cultural figures in the older and younger generations of Ukrainophiles. The stated aim includes solving the following tasks: to outline the different periods of the populist movement in Ukraine in the perception of its long-term and active participants; to analyse the approach to conceptualizing the image of the “new man” as a bearer of a new ideology and the popularization of the latter among the broad masses; to find out to what extent the dreams of the populists corresponded with reality.

As the result of the analysis carried out using the approaches of biographical, historical-literary, and empirical research methods, it was possible to establish that the tasks faced by ideological prose at the beginning of the 70s of the 19th century did not lose their relevance in the last decade of the 19th century, since the internal policy of the government towards the Ukrainians essentially did not change. According to the authors, literature could program a certain social behaviour of a significant social group, however, for objective reasons, works from the life of the intellectuals were known to a small audience.
Injury by Chornobyl: a mental and physical addiction
(Artistic models of addiction in the plays of Hryhoriy Shton and Pavlo Arie)
Authors: Fedyk Tamara
Published: December 2022

The relevance of the study is determined by the urgent need to reconsider the Chornobyl disaster in various arts. They are cinema, music, painting, and literature. The last provides an opportunity to present the connection between the macro-scale of the event and the micro-level of personal history. The problem of the role of addiction in the artistic understanding of Chornobyl as a nation's trauma is examined in the article. The subject of the study is the addictive behavior of the main characters in the analyzed plays. The goal is to analyze the poetics of artistic models of addictions caused by the Chornobyl disaster based on the material of two plays: «Canon» by Hryhoriy Shton and «At the Beginning and the End of Time» by Pavlo Arie. Psychological analysis, poetic, and modeling methods were used to achieve the goal. In the two plays, we see similar markers which point to addict characters – compulsive behavior, denial, loss of reality, and creating an alternative reality. However, playwrights choose different tools for constructing artistic models of addiction. Hryhoriy Shton gradually superimposes techniques on each other during the creation of the image of Antin. First, he uses flashbacks. Later the playwriter uses deliriums which are revealed due to artistic digressions. Also, the unique tool is hallucinations, which are not part of the structure of the text of the play, but whose consequences can be traced in the character’s actions. Instead, Pavlo Arie uses extended emotionally colored monologues in the construction of the image of Baba Prisya. The unique method of forming the image of a woman is the introduction of a surreal fictional story. The novelty lies in the analysis of the poetics of creating artistic models of addictive behavior and the expression of distinctive artistic approaches in reinterpreting the nature and consequences of the Chornobyl disaster depending on the generational affiliation of the playwrights.
Late prose by Borys Necherda: the novel “Quadro”
Authors: Saienko Valentyna
Published: December 2022

The relevance of the article is determined by the need to investigate the novel-epiphany, the novel-prediction “Quadro” by the laureate of the Shevchenko Prize Borys Necherda. The purpose of the research is to analyse the late prose of the writer in the context of the Odessa literary school. The subject of the research is the genre and style parameters of the works, in particular, the novel “Quadro”, the observations of which constitute the novelty of the research.

As a result of the research, using the hermeneutic method, the quantitative and qualitative significance of the artist’s prose was proven on the basis of a comprehensive study of the novel “Quadro” as the pinnacle of the writer’s creativity. The conducted research gives reasons to define “Quadro” as a philosophical postmodern novel, embodied in a plot form. The novel has the qualities of a parable, such as an appeal to the timeless nature of eternal problems, the philosophical nature of their justification, the wide use of biblical intertext, moral guidance, aphoristic language, generalization, and metaphorical aesthetic thinking. At the same time, the work contains characteristic features of the adventure and detective genre, although it does not contain a detective plot. The synthetic nature of the genre allows the author to include lyrical miniatures, essays, and pamphlet elements in the text.

These genre features encourage the author to consider the novel in the context of the postmodern manner of writing, which in the work of Borys Necherda manifests itself through intertextuality, archetypal images, and presentation of the work as a kind of artistic code that needs to be deciphered through the polysemy of symbols and the syncretism of metaphors and associations.

The perspectives of the research are the analysis of the reception of the late works of Borys Necherda in modern times. With his formula “Order a golden word for me”, expressed in the “Last Book” of the late period, the author indicated one of the ways of studying his place in Ukrainian culture. After all, many works have been dedicated to Necherda, his image is reflected in the canvases of artists, in particular the famous Yuriy Kovalenko, who was the prototype of the heroes of Necherda‘s prose.

Authors: Zhuravska Oksana
Published: December 2022

The purpose of the research is to analyze the symbolism, cultural codes of miscellaneous modifications of one of the most widespread Ukrainian memes in 2022 — the Russian warship meme, its role in the creation and development of the latest media discourses; it also specifies the tendencies concerning the meme use in mass media publications. The subject of the study is “the Russian warship” meme and a group of its modifications spread in the media environment after January 24, 2022. It is stated that the media area of the meme’s functioning is extremely wide, it is not only spread verbally but also visually, represented by a range of media and mass media genres: from posts on social networks from the state public officers to individual media projects and media branding. A peculiarity of this meme is also the fact that it crosses the borders of a nationally-oriented media environment by the rules of news-related genres as topical and socially important information. Another peculiarity of the meme’s circulation is the fact that its verbal core is an obscene expression, the use of which is exceptionally limited according to the standards of numerous lingual cultures. Thanks to the methods of narrative analysis, generalization and interpretation the author of the article determines the meme’s role in the formation of new kinds of discourse of heroics and immortality, which are important in the conditions of hybrid war and information confrontation.

As a result of our research, we explain that the meme becomes a symbol of brave and desperate resistance to unjustified military aggression, a violation of the world order established after World War II. Studying an ironic philological media discourse of the Russian warship meme exhibits its transgressive nature on one hand, i. e. the function of prohibitions overcoming during critical extremal situations and on the other hand, demonstrates the significance of the meme for national self-identification processes. The article specifies the tendencies for change in meme’s media functionality, which lies in the gradual down-toning of the obscene categorical nature of a verbal structure through its substitution with ellipsed options, metaphoric euphemisms, allusive expressions, etc. The novelty lies in the study of the functionality of the meme in various media discourses, in particular professional journalistic, heroic mythological, ironic philological, etc. Further study of the meme at different stages of its media lifecycle can be perspective.

The article is presented in two parts. This issue deal with the linguacultural code of this meme.
