Published: July 2023

This paper elaborates on policies, strategies, and implementation of Smart Cities in Indonesia. Due to regulatory, strategy, and implementation problems for Smart City, there are still differences in understanding and strategy in its implementation. Smart urban governance is part of a smart city, so one strategy to implement smart urban governance is a smart city policy in Indonesia. There is a fragmentation of inconsistent approaches, policies, implementations, and strategies in practice. This research will develop arguments, analyze published articles and regulations, and map them out. The research method used was a qualitative approach. The data sources used were articles from Scopus which found 213 articles using the keywords smart city policies and smart urban governance and regulations, which were then processed using VOSviewer and Nvivo 12 Plus software. This study indicated that to implement smart urban governance in Indonesia, strategies such as the first need to be supported by the central government to make a policy regarding smart cities, including smart urban governance, followed by smart city policies in the towns in Indonesia. Second, there are technological developments that support the implementation of smart cities. Third, there are institutional and human resource factors, but these are still obstacles to implementing smart cities in Indonesia. Meanwhile, the urban issues developed in Indonesia are mega-urban in the big island, urban management and financing, housing for lower-income, sustainable urban infrastructure, and resilient disaster mitigation and management.

Published: July 2023

Commitment is vital in keeping and maintaining integrity within the organization, especially in public organizations. In addition to maintaining integrity, commitment is much needed in organizational change. People with affective commitment who join the organization of their own volition will support the changes made if they feel they are good for the organization. This quantitative study used primary data collected with an online survey facility. The data collection used the non-probability sampling technique of convenience sampling. The sample involved 255 active Directorate General of Customs and Excise employees with work locations across various parts of Indonesia. The data obtained were processed with JASP v 0.16 application with simple regression techniques and Structural Equation Modeling (SEM). The study’s results support the initial hypothesis that emotional intelligence positively affects employees’ affective commitment. In addition, the study’s results support the second hypothesis that public service motivation mediates the effect of emotional intelligence on affective commitment.

Published: July 2023

This article explored collaborative governance risk management on implementing tobacco control policy in Kulonprogo Regency and Pekalongan City. The research methods used qualitative methods based on primary and secondary data. The authors collected the primary data through interviews with some actors. In contrast, the secondary data comprised online mass media and previous research on relevant topics. This article also uses the tool Nvivo12 Plus to help with data processing. The results showed that the collaborative governance of Kulonprogo Regency and Pekalongan City had some risks in their collaboration. Kulonprogo Regency could resolve those risks through decision-making to achieve the integrated mechanism. This step is easy to implicate because the actor has high cooperation to solve their problem through a joint decision. While the risk collaboration of Pekalongan city could not be solved properly cause of the lack the mechanical integration of the actor in that collaboration. The actor has different principles and impacts on a joint decision to achieve an integrated mechanism when solving the problems.
A study of psychological impact of acne vulgaris on quality of life using CADI & DLQI scoring in patients attending dermatology OPD in tertiary care hospital
Authors: D Swathi , Aithal Sanath
Published: July 2023

Acne Vulgaris is a chronic inflammatory disease with multifactorial etiology. It is one of the leading reasons for visiting a dermatologist. Acne patients undergo considerable amount of psychological impairment as face is socially and psychologically the most important body region. There is no sufficient data available on the Impact of acne on QoL in Indian patients.

To Determine the Impact of Acne Vulgaris on Quality of Life using two different scoring systemsi.e.CADI & DLQI

It is a hospital based cross sectional study done at dermatology Opd in tertiary care. It is a one year study from January 2016 to December 2016. 500 diagnosed cases of acne Vulgaris of the age groups 15-30 were studied. Informed written consent and Photographs was obtained from all patients. A complete history, clinical examination, was done in all patients. A baseline ‘global acne grading system’ was being performed. Quality of life in acne vulagaris patients were studied using pre- structured questionnaire of DLQI (Dermatological life quality index) & CADI (Cardiff acne disability index scoring systems).

Based on GAGS, 80% of the patients were mild, 19% moderate and remaining 1% had severe grading of acne. Majority of the patients had very large effect on quality of life (76%) on DLQI scoring and medium impact in quality of life (86%. 12.4%) on CADI scoring.

The results of the study show that majority had medium & large effect on QoL. Hence the disability caused by acne must be taken into account when individualizing treatment by health professionals and include QoL measurements to provide better care.

: Melasma is one of the most common causes of hyperpigmentation and is a prevalent cosmetic concern for patients. Tranexemic acid is an effective mode of treatment available in both oral and topical forms.

: To evaluate and compare the therapeutic effectiveness of topical and oral tranexamic acid for the treatment of melasma.

A total of 84 patients who presented to dermatology OPD with melasma were divided into two groups, namely A and B. Group A patients were treated with oral tranexamic acid 250 mg twice daily, and patients in Group B were treated with topical 5% tranexamic acid with follow-up every 4 weeks until 3 months.

Among the oral treatment and topical patient groups, a statistically significant difference in the mean percentage of reduction in MASI score from baseline was observed at 12 weeks (61.31±9.48 for oral vs 52.64±8.03 for topical) with p<0.05. Systemic side effects like abdominal pain, nausea, and oligomenorrhea were observed with oral tranexemic acid, while topical side effects like erythema, skin irritation, and xerosis were observed with topical tranexemic acid treatment.

Oral tranexamic acid gave a more promising result when compared to topical tranexamic acid. Despite having GI disturbances with oral tranexamic acid, it had more patient compliance and could be a promising therapeutic approach for melasma.

Myriad of therapeutic modalities for warts are available but none promises complete response. Despite adequate treatment, the virus may persist in the surrounding tissues leading to recurrence. Immunotherapy is considered better than destructive options where there are multiple lesions, extensive involvement and is best suitable for paediatric patients. The aim of the study was to evaluate the efficacy and safety of intralesional BCG vaccine in the management of cutaneous warts (common warts, plantar and periungual warts).

Patients of age 12 years and above clinically diagnosed with cutaneous warts and presenting consecutively in the outdoor clinic of Dermatology, Venereology & Leprosy Department of Dr. R.P. Govt. Medical College, Kangra at Tanda, Himachal Pradesh between June 2021 to May 2022 were enrolled. BCG vaccine was administered into the largest wart intralesionally and the injection was repeated every 3 weeks for a maximum of four injections or till the complete clearance of warts, whichever was earlier. The efficacy was assessed every 3 weeks and patients were followed up at 3 and 6 months.

Majority of patients were in the age group of 14-53 years. The study showed therapeutic response in 35.08% (20/57) patients and partial response in 63.15% (36/57) patients while there was no response in 1.75% (1/57) patients at the end of 12 weeks with a very low recurrence rate (5.2%). Plantar warts have responded excellently showing complete clearance in 91.5% and partial response in 9.5% of the patients followed by palmar warts achieving complete response in 60% and partial response in 40% of the patients.

The reconstituted BCG immunotherapy is a cheap, effective and easily available therapeutic option which can easily be practised routinely. However, due its considerable adverse effects as compared to other immunotherapeutic agents, we do not recommend it to be the first line agent.

Published: July 2023

Comedones occur in a variety of skin conditions especially on the face. Comedone extraction using an instrument called comedone extractor is a commonly employed technique to remove them. Comedones may however be present in uncommon sites such as concha of ear. Using comedone extractor in concha of the ear is difficult as it is deep and the the surface is firm. It may also cause injury to the patient. In such situations, ‘pen punching technique’, first described in 2015 may be employed to extract comedones easily. We describe a case of a 23-year-old girl with comedones on the concha of both ears which we removed using this technique.

Published: July 2023

Семейное насилие получило в Российской Федерации катастрофические масштабы, которые представляют опасность фундаментальным критериям безопасности и жизни социума. Профилактика семейного насилия затруднена длительным периодом развития проблемы. Несмотря на активное внимание к данной тематике как отечественных, так и иностранные ученых, на сегодняшний день в Российской Федерации не просматривается перспектив по решению проблемы домашнего насилия. Цель данного исследования – выявить наиболее распрастраненные виды и причины семейного насилия в настоящее время и определить перспективы социальной работы с кризисными семьями. Авторами был проведен социологический опрос (150 респондентов с опытом соприкосновения с насилием в семье и более 20 экспертов, в числе которых юристы, социальные работники, педагоги и психологи). Результаты показали, что проблема оценивается респондентами как острая и распространенная, но 95 % опрошенных не знают, куда обращаться за помощью.  Эксперты и респонденты массового опроса оценивают существующую систему профилактики в целом как неэффективную и пессимистически оценивают возможность первичной профилактики домашнего насилия. В качестве наиболее важного направления профилактической работы участники исследования отметили социально-педагогическую профилактику. Сделан вывод о необходимости информирования максимально широких слоев населения об организациях, в которых можно получить помощь, а также о предоставляемых мерах поддержки и защиты.

Published: July 2023

The percentage of undernourished toddlers on Java Island averages 8.5 %. This number is relatively high compared to the average incidence of undernutrition in toddlers in Sumatra, 3.3%. This study uses OLS, GWR, and GWANN to explore undernutrition in toddlers data on Java Island. We use cross-validation to determine the optimum bandwidth in GWR and GWANN methods. GWANN uses a single hidden layer with several hidden neurons where the number of hidden neurons is selected based on RMSE. We use indicators RMSE, MAE, and MAPE to determine the best method for modeling data on undernourished toddlers in Java. By comparing the final results, the best method for modeling data on undernourished toddlers in Java is GWR. There is a relationship between regions on the influence factor of undernutrition. Most adjacent areas, ranging from East Java to DKI Jakarta, have the same influence factor: the percentage of skinny toddlers.

Authors: Mehmood Asim , Bhaumik Amiya
Published: July 2023

This paper investigates the mediating role of environmental knowledge and its effect on green pricing, promotion, and consumer buying behaviour in hypermarkets in Ajman, UAE. Two hundred twenty questionnaires were distributed to hypermarket customers, with a return rate of 76.8%. The study utilized SPSS version 28 to conduct exploratory factor analysis on 21 items, focusing on item loading, convergent validity, and internal consistency. Correlation tests were performed to determine the strength of associations between variables, and multiple regression and mediation analysis was used to test the hypothesis. The results found that green pricing substantially affects consumer buying behaviour and environmental knowledge. The results showed that green promotion considerably impacts consumer buying behaviour and ecological knowledge. Additionally, environmental knowledge partly mediated the connection between green prices and CBB and green promotion and CBB. However, the study's findings are limited to Ajman, UAE, and cannot be generalized.

DOCTORS MEETING PATIENTS WITH DISABILITIES
Authors: Gere Hajnalka , Pető Ildikó
Published: July 2023

The paper explores a topic that affects everyday life: the encounter between doctors and patients with disabilities. The aim of the research was to find out how doctors and medical students think about disability, people with disabilities, and their encounters with them, in the course of their work. Despite the fact that age, the number of years spent in practice, and the areas of specialisation of the 10 interviewees present varied pictures they express many similar opinions in their responses. The responses point out that during their university years, they had heard little about the different aspects of disabilities in theoretical classes and during their practice so they really only had everyday knowledge and stereotypes about their disabled patients. The question arises: can doctors with a high social prestige set a positive example to the rest of society when it comes to the treatment of people with disabilities? The question then goes on to raise the need for a wider study, which should include other health professionals.

The paper presents the results of using multiplicative indices for species identification of polyploid green toads of Central Asia. Live adult individuals of Bufotes baturae (24 females and 17 males) from the territory of Tajikistan and B. pewzowi (14 females and 24 males) from Kazakhstan, Uzbekistan and Tajikistan were studied. The animals were caught in nature, measured and immediately released. The species belonging of the studied green toads was established by cytogenetic methods. According to the results of discriminant analysis, six proportionality indices were significant for the species identification of females. The females of B. batura and B. pewzowi formed separate non-overlapping clusters in the discriminant function space, and the level of their reliable classification was 100%. For the identification of B. batura and B. pewzowi males, four significant body proportionality indices were identified using discriminant analysis. The clusters of these two species in the space of discriminant function touched, and the level of correct classification was 97.6%. As a result of our research, one multiplicative index common to males and females was identified for highly reliable identification of B. baturae and B. pewzowi, as well as one multiplicative index separately for males and females of the studied species. The authors conclude that multiplicative indices based on standard morphometric indicators can be used for the practical determination of polyploid green toads.

This research paper examines the influence of internal factors (female body weight, body condition) and external ecological factors on the reproductive parameters of females, as well as on the reproductive ecology of adult individuals of anuran amphibians. Among the most significant reproductive characteristics of females are the number of eggs in a clutch, the proportion of reproductive products to female body weight (contribution to reproduction), and the average weight of eggs. The body weight of the female and the ecological (meteorological) conditions of her activity during the year preceding spawning, as well as the hibernation conditions, have the greatest impact on the quantitative expression of these parameters. The proportion of reproductive products to female body weight in anuran amphibians usually ranges from 13 to 30%. Climate warming can directly affect the reproductive parameters of females, the survival of metamorphs, and the phenology of the spawning period.

The paper presents the results of laboratory reproduction of Regel’s racerunner (Eremias regeli). Offspring was obtained from natural individuals (2 females and 2 males) captured in the vicinity of the Bokhtar town (Khatlon region, Republic of Tajikistan). Captive-born animals (3 females and 2 males) began laying eggs at the age of 7 months. The lizards from nature reproduced twice a year, while the animals obtained in the laboratory lay eggs up to three times per season. The clutches of both natural and laboratory lizards contained from 2 to 4 eggs. In total, 9 fertile clutches and 26 eggs were studied, which 18 newborn lizards were obtained from. The mass of one clutch ranged from 28.97 to 54.68% of the female mass. The eggs had a length of 12.3–18.1 mm, a width of 7.3–9.4 mm and a weight of 0.53–0.95 g. Incubation lasted 56–99 days. The newborn lizards had a body length of 26.5–35.1 mm, a tail length of 41.1–60.0 mm and a mass of 0.60–1.11 g. Comparing the reproductive parameters of E. regeli with other representatives of the tribus Eremiadini, the authors note relatively small sizes of adult females, their low fertility, but large sizes of eggs and newborn juveniles.

Published: July 2023

The number of nitro compounds of the anthropogenic origin in the general nitrogen cycle is steadily increasing, which leads to an increase in nitrates in products and increases the nitrate-nitrite load on the human body. The aim of the study was to determine the amount of nitrates in raw vegetables and their processed products. Vegetables with high (beetroot, cilantro, radish, green onion), medium (zucchini, carrot, cucumber) and low nitrate content (potato, tomato, onion) have been selected as the objects of the study. For the qualitative determination of nitrates the reactions with diphenylamine have been carried out. For quantitative determination, the ionometric determination of the pH-meterionomer Ecotest 2000 has been carried out using an ion-selective electrode ECOM-NO3. In the course of the study, it has been found out that the vegetables entering the Magnit retail chain do not exceed the MPC in terms of nitrate content, with the exception of the radish and zucchini. When cooking in a microwave oven the amount of nitrates increases dramatically. When cooking vegetables «until ready», the amount of nitrates in vegetables decreases, but their amount in broths increases. With prolonged heat treatment the amount of nitrates increases both in vegetables and in the broth. When freezing and defrosting vegetables in a closed container, a decrease in nitrates is observed, and when defrosting in an open container, the level of nitrates increases sharply. Thus it is recommended not to use a microwave oven during the cooking process. During boiling first drain the water, then pour in new one and boil until ready. Ready-made vegetables should not be left in the broth due to the reverse adsorption of ions. Vegetables should be defrosted in a closed container.

The weakening of the manmade load on the environment has become a global goal of humanity. The accumulation of toxic substances in effluents can increase the acceleration of pollution of the planet’s watersheds, resulting in biota pollution. To solve this problem, it is necessary to create photocatalysts that cause self-excitation under the ignition of light. Also, important parameters of photocatalysts are simple synthesis and low cost. This article demonstrates a one-step approach to the synthesis of carbon nanostructures (CNS) with photocatalytic activity. For this purpose, the “green chemistry ” method is used – hydrothermal treatment of various polysaccharides (sodium dextran sulfate (SDS), starch, pectin), which opens up the possibility of recycling products. A comprehensive study of the properties of the synthesized CNS has been carried out. To study the optical properties of CNS, absorption and luminescence spectroscopy, and IR spectroscopy, have been used. The CNS obtained have been successfully used in the processes of photocatalytic destruction of a model of the organic dye tartrazine, which is widely used in the fiber and textile industries. The effect of lyophilization on the photocatalytic properties of СNS has been studied, and cytotoxicity has been evaluated.

Cycvalone is an analogue of curcumin (EE conformation), exhibits a wide range of biological activity (antioxidant, hepatoprotective, membrane stabilizing, anti-ulcer) and is used in medical practice as a choleretic. Numerous methods of producing cycvalone are known, including industrial ones, but its reactions have been studied much less. Some reactions of cycvalone with N, C-nucleophiles (hydrazines, malononitrile) have been carried out. Reactions with getarylamines that could lead to the synthesis of compounds including pharmacophore fragments remained completely unexplored. We have used cycvalone as a substrate for the synthesis of nitrogen-, oxygen-containing heterosystems of a number of chromenopyrimidine, aminochromencarbonitrile, indazole, triazoloquinazoline. The structure of the obtained new substances has been established by spectral methods (IR, NMR). Schemes of formation of reaction products have been proposed.

One of the modern approaches to solving environmental problems of accumulation and deposition of production and consumption waste is the implementation of “green economy” and “closed cycle” economy models. This approach makes it possible to increase the resource utilization rate and reduce the negative impact on the environment. The study of the possibility of joint disposal of waste from various industries, for example agricultural and industrial waste, is promising in this area. The analysis of the current state of work in this direction is carried out, using the example of the possibilities of joint utilization of phosphogypsum and organic waste. A new eco-friendly approach to the utilization of a large-tonnage secondary material resource – phosphogypsum together with organic waste is proposed. Phosphogypsum acts as a matrix for the production of complex organomineral fertilizers and meliorants of complex composition, the introduction of the organic component of fertilizers is carried out in the finished and neutralized liquid phase. Agricultural waste, municipal waste, s ewage sludge can be the raw materials for the organic component. The effectiveness of the complex organomineral fertilizer an d meliorant based on phosphogypsum (90% by weight) and the liquid fertilizer “Rabiol” with the inclusion of a highly selective sorbent based on molecular imprinted polymers to imazamox, a resistant herbicide of the imidazolinone class, is shown.

Graft copolymers of polysaccharides with acrylic monomers combine biodegradability, biocompatibility, the environmental friendliness of natural polymers and the increased thermal stability, chemical and mechanical resistance of synthetic polymers. This paper describes our search and analysis of the literature in English for 2002–2022 devoted to the graft polymerization of acrylamide, acrylic acid and 2-acrylamido- 2-methylpropanesulfonic acid onto xanthan and glucomannan macromolecular chains. It has been found that the synthesis of grafted copolymer chains proceeds by a radical polymerization mechanism using thermal homolytic decomposition of the initiator or microwave irradiation, or radiation initiation and frontal polymerization in some cases. Depending on the method of the reaction, the synthesis time of a graft copolymer varies from several minutes to several hours. The influence of the synthesis conditions and parameters on the monomer conversion, structure and properties of the resulting polymer has been considered. It has been found that decreasing the polysaccharide/monomer ratio and increasing the initiator concentration raise the efficiency and degree of grafting. Several methods for characterization of graft copolymers are discussed, including: IR spectroscopy to analyze the chemical structure of a sample, scanning electron microscopy to characterize structure, supramolecular ordering and porosity, differential thermal analysis to evaluate thermal effects and thermal stability. The effect of the synthesis conditions and the pH of the sorption medium on the water absorption and sorption capacity of this class of graft copolymers are discussed. The broad potential of graft copolymers for repeated cycles of absorption and release of liquid medium without loss of functional properties has been found. This opens prospects for the use of graft copolymers of xanthan and glucomannan with acrylic monomers as materials for water purification from metal ions and cationic dyes, targeted delivery and prolonged action of drugs and wound coatings for wound treatment.

This abstract presents the results of screening for allelopathic activity of three pairs “aboriginal-exotic” of comparison species of herbs, including invasive species, systematically related at the level of the genus. It was shown that a 1% leaf extract of Solidago virgaurea and S. canadensis, Pulmonaria obscura and P. saccharata, Veronica serpyllifolia and V. filiformis had a similar or equal inhibitory effect on the germination and growth of test-plant roots in biotests owing to its chemosystematic correlation. Extracts of Solidago and Pulmonaria species slowed down the rate of germination and root growth by 1.5–2 times lower than the control. In the Salidago sp. experiment options the dynamics of the processes developed according to the type of stress-reaction. The absolute rate of root growth at the exponential stage differed twice in the Solidago sp. options: 16.8±0.43 and 8.99±0.23 mm/day in native and exotic specie, respectively. The total germination was close to or equal to the control level. In a comparison pair Pulmonaria sp. germination decreased by 58.66 and 43.5%. V. filiformis extract inhibited germination by 24.4% more than the native species. Extracts 0.05% extracts of Solidago sp. had no effect, P. saccharata and V. filiformis extracts caused the effects of hormesis. P. saccharate option produced an – acceleration of the absolute and relative root growth rate of the test-plants by two times, exceeding the total length of the roots by half compared to the control and the native species. In the V. filiformis option, the rates of germination and root growth was inhibited by 24.7 and 50.2% of the values of the paired species, respectively. The comparative method increases the level of analysis of bioassay data, allows for a deeper study of the specifics of test-plants reactions, and allows the evaluation of the modes of action of allelochemics.
THE FREE HIGHLANDER NEWSPAPER AS AN ORGAN OF INDEPENDENT NORTH CAUCASIAN DEMOCRATIC THOUGHT DURING THE CIVIL WAR
Authors: Turpalov Lema A.
Published: July 2023

The revolutions of 1917 gave impetus to the development of multi-party journalism in the North Caucasus. The thesis about the vanguard role of the local Bolshevik press in the political arena in these crisis conditions, prevalent in the overwhelming majority of historical and journalistic studies of the Soviet period, does not correspond to reality. The concept that sheds light on the fact that during the February and October revolutions the Bolsheviks used local liberal and enlightenment publications more pragmatically to promote their ideas and established a monopoly over the press in the post-October period is relevant at the present stage. In the course of the civil war a branched system of small press developed in the region, which has so far remained beyond the scope of journalism historians.

Authors: Soldatova Olesya B.
Published: July 2023

The article is devoted to the study of the semantic and contextual features of the inaugural speeches organization in cases when religious concepts function in them. The relevance of the study is determined by the importance of analyzing the pragmatic characteristics of the religious concepts functioning in American presidents’ inaugural speeches. Research methods are cognitive-discursive analysis, contextual analysis, method of quantitative processing of the material. Empirical material contains 57 inaugural texts, in which the functioning of religious concepts is noted in 296 contexts. US presidents regularly use religious concepts in their inaugural speeches, in some cases of their functioning, inaugural texts have certain structural features that are emphasized in this work. The article analyzes the main pragmatic guidelines for using these concepts: actualization of the moral and ethical values of society, underlining the importance of continuity in the history of the state, implication of the meaning of the divine election of the president and the idea of a special relationship of the Creator to the American people, seeking divine help in leading the state. The study of the role of the religious concepts functioning in the inaugural speeches of American presidents allows us to consider in more detail the linguistic and extralinguistic features of political discourse texts.
THE CATEGORY OF AN EVENT IN ROCOCO PROSE (ON CRÉBILLON FILS’S NOVEL “LES ÉGAREMENTS DU CŒUR ET DE L’ESPRIT OU MÉMOIRES DE M. MEILCOUR”)
Authors: Semenchenko Yury I.
Published: July 2023

The category of an event is one of the most problematic areas in the contemporary theoretical literary studies. Both foreign and Russian scholars pay attention to singling out a set of markers of an event. It is no wonder that the so-called realistic prose is usually chosen as the concrete historical material for the illustration of the theoretical concepts due to its claims to the most authentic and realistic reproduction of the objective reality. The later involves the highly dynamic web of the socio-political, cultural, historical and family-private events that set a context of the human existence. Hence there persists a tendency to transpose the criteria of an event and eventfulness, developed on the basis of the realistic prose, on the texts built on different artistic, philosophical and aesthetic premises. Although Crebillon’s novel “Les Égarements du cœur et de l’esprit ou Mémoires de M. de Meilcour” belongs to the stage of the literary process outlying far from realism as an ideologic and artistic movement, it is still closely associated with the literature focused on the referentiality of the depiction. In this paper with the help of the criteria of the eventfulness set out in Schmid’s monograph “Narratology” we explore how the eventfulness of “Les Égarements du cœur et de l'esprit”, seemingly corresponding to the notions of the poetry of reflexive traditionalism, eludes its description in the categories of “unpredictability”, “consecutiveness”, and “nonrepeatability”. Realistic features of an event are becoming more blurred against the background of the narrator’s concentration on motivation of the protagonist's behavior which once in the high society passes the way from the struggle for the autonomy of Self to acquiring verbal and nonverbal behavior strategies.
DIALOGUE OF MAN AND LIVING WORLD IN M.M. PRISHVIN’S DIARIES (1873–1954)
Authors: Izotov Vladimir P. , Mikheicheva Ekaterina A.
Published: July 2023

The genre of the diary was widespread in the Russian literature of the 1920s–1930s. The most famous works are “Cursed Days” by I. Bunin, “Diary” by L. Andreev. M. Prishvin’s “Diaries” are among the most voluminous and significant in Russian literature. The genre of the diary is especially vivid in the period from 1905 to 1954 with selected themes in the foreground: the world of nature, relations with iconic personalities of historical period, and the events of the author’s own life, which at the same time are an artistic chronicle of the era. Prishvin’s diaries are philosophically charged, since the author also addresses universal themes and eternal issues. In the writer’s worldview, nature is eternal, untouched by social shifts, which happen in the twentieth century full of turmoil. If war violates the law of life, according to which a person lives as long as it was measured by God, the close people become the support for Prishvin in the most difficult moments. He is writing about the beloved woman, relatives, friends, poets and writers, even if there are discrepancies in creative attitudes, such as, for example, between realists and symbolists. The diaries which M.M. Prishvin kept for fifty years became evidence not only of the life of the writer himself, but also of an entire epoch, with its revolutions, wars and the lives of ordinary people against the background of historical cataclysms. Despite all the trials that befell the writer and his loved ones, in his soul he remained a romantic, endlessly loving nature and the whole living world.
