Background/Aim. Since the coronavirus disease 2019 (COVID-19) pandemic led to a strict lockdown in Serbia, the population has experienced drastic lifestyle changes. Physical distancing, self-isolation, limited availability of essential food products, and the stress related to the availability of therapy during the pandemic particularly affected the lives of vulnerable groups, such as breast cancer (BrC) patients. The aim of this study was to examine the changes in eating behaviors and physical activity of postmenopausal BrC patients on adjuvant hormonal therapy under the COVID-19 lockdown conditions. Methods. This observational retrospective pre-post cohort study included 32 women treated with aromatase inhibitors (AIs) who responded to telephone interviews using a structured questionnaire. The questionnaire aims to collect data on eating habits (intake of certain foods on a daily/weekly basis, as well as changes in the usual choice of food), intake of supplements, changes in weight, and physical activity before and during the lock-down. Results. The results showed that, due to problems in obtaining groceries, the patients cooked and consumed homemade sweets and fruit more often (47% of the respondents), while fewer (31%) consumed fresh fish. Nearly 41% of patients reported increased food intake, and 88% reported decreased physical activity, which led to an in-crease in body weight in as many as 47% of subjects. The intake of supplements was doubled. Conclusion. The COVID-19 lockdown with home confinement exacerbated health risks and affected dietary patterns and physical activity, which may have had a negative impact on the long-term health of BrC patients treated with AIs.

Published: March 2024

Introduction. National security of any state is ensured through development of the various spheres of its life — spiritual, political, military, economic and others. However, the fundamental factor ensuring existence of any society is availability of accessible quality and quantity of food to the citizens. Therefore, the goal of the state socio-economic policy of Russiais to ensure people’s food security. The article analyses the state policy and practices of Russia in countering the threats to the food security of the country in the modern difficult geopolitical settings.

   The relevance of studying the food security system of the Russian state is induced by one of the priorities of the state socio-economic policy implying the development of the food security threat preventing and countering measures as the fundamental condition of existence of the society.

   The aim of the study is to analyse the criteria of the state governance efficiency on ensuring the food security of the country, to study the state of the art in this field as well as to identify the existing threats and propose the countering measures.

   Materials and Methods. The research was conducted using the methods of structural-functional and statistical analysis, content analysis of the normative legal acts in the field of food security, at both national and international levels, the comparative-historical method, comparativism and other methods.

   Results. The state of the art of the food security system of Russia, which is an integral part of the national security of the state, has been analysed. The regulatory documents and statistical data on the state of the art of the food security of Russia have been investigated. The measures for ensuring the Russian Federation food security have been proposed through expansion of the domestic production of the environmentally friendly and safe for the human health products and other kind of products that is a necessary condition for preserving the population and the nature of our country and the decent standard of living of the Russian citizens.

   Discussion and Conclusion. The degree of ensuring the state food security has significantly improved, but has not reached the normative threshold values for the whole range of goods. Provision of the high-quality affordable food to the Russian citizens remains a riskogenics factor. The economic sanctions imposed by the Western countries against Russia are a newform of the hybrid warfare. The conclusions drawn upon the research aim to supplement and expand the scientific knowledge on the conditions of ensuring the food security of the Russian state that is the most important concern of the government, because food is the basic condition for existence of all the living beings on the planet. The independence of the state and its national sovereignty depend on ensuring the food security.

Artikkelissa monimuotoisuutta lähestytään konstruktiivisen professiokäsityksen ja diskursiivisuuden näkökulmista. Artikkelia varten on haastateltu kymmentä suomalaista päätoimittajaa touko–elokuussa 2022. Analyysissa esitetään erilaisia päätoimittajien haastatteluista esiin nousseita tulkintarepertuaareja. Tutkimusaineiston perusteella voidaan sanoa, että päätoimittajat haluavat lisätä etnistä monimuotoisuutta toimituksissaan, koska se liitetään ajatukseen journalismin tavoitteesta edustaa koko yhteiskunnan kirjoa. Etnisen monimuotoisuuden vahvistamisella vaikuttaa kuitenkin olevan kaksi estettä: etnisyyteen liittyvän sanaston hapuilevuus sekä journalistin ammatin ja siihen liittyvän osaamisen tiukka määritelmä. Keskeisiksi ongelmiksi mielletään muualta Suomeen tulleiden journalistien puutteellinen kielitaito, suomalaisen koulutuksen ja toimituskulttuurin tuntemuksen puute sekä toimitusten rajalliset resurssit ja yksilökeskeiset toimintatavat.

Analysis of the Results of Experimental Measurements of Vibration and Internal Noise of the Power Station Car of a Recovery Train Generated During Operation of Diesel Generator Units
Authors:   Rostov State Transport University, Frolova D.S.
Published: March 2024

Recovery trains are a specific type of railway formation comprised of a huge amount of special equipment used for prompt and high-quality elimination of accident consequences and restoration of railway communication. Depending on the type of recovery train, power station cars can have various configurations and be equipped with different numbers of autonomous diesel generator units required to perform the preset functions. Diesel generators installed in these cars are located in proximity to workplaces and the place of locomotive drivers, which creates an adverse vibroacoustic environment during a working shift. The article aims at the detection of potentially hazardous and harmful production factors emerging inside a power station car and the experimental investigation of noise and vibration. The experimental investigations inside power station cars have detected a significant excess of vibroacoustic characteristics compared to the established sanitary and hygienic norms. The consequences of noise-induced hearing loss and vibration disease caused by the long-term effect of noise and vibration are known. Hence, the problems of the investigation are urgent and a matter of great scientific and technological, social and economic importance. Within the framework of the investigation, it has been concluded that considering the established class of working conditions and production tasks of a locomotive driver of a power station car it is reasonable to take measures to reduce the general vibration level at the driver’s workplace. The goal can be achieved via the modernization of the driver’s chair racks by using vibration-absorbing elements. In the course of the development of engineering solutions, the fact that the sound field is formed from air-based and structural components as well as the specific car configuration have been considered.
Improving the Efficiency of Treatment of Sewage Systems
Authors:   National polytechnic university of Armenia, Chibukhchyan O.S.
Published: March 2024

Today, the level of accessibility to water supply and sewage systems, their technical condition, and the quality of maintenance and cleaning are among the elements determining the quality of life in cities and small settlements. Efficient sewage systems are vital to maintaining environmental safety, the established sanitary norms, and the conditions of people’s comfortable accommodation. All these factors require the communal services of cities and megalopolises to maintain sewage systems in proper technical conditions, minimize operational costs, extend the service life of the systems, and organize and implement new treatment technologies. According to experts, the main enemy of the internal sewage systems is grease abundant in domestic wastewater. The initially warm wastewaters are soon cooled in the pipe, and grease impurities settle on the walls of the sewage pipe. The layer of grease deposits may trap other impurities, thus contributing to the formation of a larger and more complex clog. The development and implementation of new contemporary methods of treatment of sewage systems and, particularly, the use of ultrasonic vibrations reduces operational costs, extends the service life of the systems, and ensures environmental safety. For these purposes, the ultrasonic generator UZG-10 of 10 kW capacity was used, as well as the magnetostrictive ultrasonic transducer with a magnetoconductor with three rods. The middle rod is equipped with finished windings that rigidly connect the free ends of the other rods. The provided scheme of transducer manufacturing increases the efficiency of pipe treatment and significantly reduces energy costs.

Authors:   National Research Moscow State University of Civil Engineering, Gvozdev E.V.
Published: March 2024

The article presents an integrated safety system established at explosion- and fire-hazardous plants; the system requires continuous improvement and development. The transition of the system to a qualitatively new level is possible via using a justified expert method to determine the quantitative value (measure) of the influence of subsystems of industrial and fire safety, labor protection, and production structural units. This allows to detect significant gaps, develop measures to correct the deviations detected, and monitor the dynamics of improvement of influence factors within the established period for each subsystem (industrial and fire safety, labor protection, and structural production units). The article aims to improve the condition of the integrated safety system at an enterprise via the assessment of the influence of personnel (industrial and fire safety, labor protection, and structural production units) performing their labor functions to ensure the high-quality functioning of the system. To achieve the goal, two problems had to be solved. In the course of solving problem № 1, the justification for using the prioritizing method was provided; the method has a distinct advantage over the other expert methods of assessment, as it has no limits for boundary expansion in order to obtain adequate results. It has been demonstrated that the application of the prioritizing method and the Gaussian normal distribution function in conjunction enables solving problems by choosing a specific subsystem by experts (industrial and fire safety, labor protection, and structural production units) deviations of which, due to its flaws (errors), have caused the primary factors of damage from accidents and fires. In the course of solving problem № 2, an example confirming the adequacy of the application of the prioritizing method together with the Gaussian normal distribution function was demonstrated. Based on the systemic analysis of methods used in practice, the justification of application of the expert method that enables obtaining quantitative values displayed as the influence coefficient was obtained, which indicates certain deviations and enables the correction of the personnel management model (industrial and fire safety, labor protection, and structural production units).

Many of the equipment and machines we use in our everyday lives have changed due to major advancements in today's technology. Smartphones, which have made great progress especially in the last decade, perform many tasks in addition to interpersonal communication. Controlling robots, which are increasingly used in daily life and widely included in the literature, is one of these tasks. In this study, the pure pursuit algorithm was used to control the position of a non-holonomic differential drive mobile robot, and the path information to be tracked was received from an Android mobile device as a reference. An application design has been carried out for Android devices. The information for the path drawn here was transferred via the internet to a Google Spreadsheet. Coordinate information obtained from Google tables in MATLAB was separated as x and y axis information and entered into MATLAB/Simulink as waypoints of the pure pursuit algorithm and the position control of the robot was carried out. Error analysis was made by taking the differences between the reference path and the actual movement and the control performance was examined. Additionally, the effect of the approach distance value of the pure pursuit algorithm on the error is presented.

Informationally advantaged lenders and the credit derivative market: Evidence from Loan only Credit Default Swap (LCDX)
Authors: Davaadorj Zagdbazar , Brusa Jorge
Published: March 2024

This paper explores the informational role of the Loan Only Credit Default Index (LCDX) on the pricing of syndicated loans. Despite an extensive body of research on credit indices and loan pricing, limited studies have comprehensively assessed the complex relationship between the LCDX and individual loan spreads. Contrary to indices like the CDX, which are largely linked to corporate bonds, the LCDX directly pertains to the syndicated secured loan market, offering valuable insights about the overall credit default market and the cost of credit risk insurance. Preliminary results reveal a pronounced positive correlation between the LCDX spread and the syndicated loan spread, particularly noticeable amongst borrowers with lower credit quality. The paper highlights the LCDX's pivotal role in conveying secondary credit market information, with critical implications for credit risk management and financial regulations.

Published: March 2024

This systematic review evaluated psychiatric adverse events (AEs) following vaccination against coronavirus disease 2019 (COVID-19). We included studies that reported or investigated psychiatric AEs in individuals who had received an approved COVID-19 vaccine in the Republic of Korea. Systematic electronic searches of Ovid-Medline, Embase, CENTRAL, and KoreaMed databases were conducted on March 22, 2023. Risk of bias was assessed using the Risk of Bias Assessment Tool for Non-randomized Studies 2.0. The study protocol was registered in the International Prospective Register of Systematic Reviews (CRD42023449422). Of the 301 articles initially selected, 7 were included in the final analysis. All studies reported on sleep disturbances, and 2 highlighted anxiety-related AEs. Sleep disorders like insomnia and narcolepsy were the most prevalent AEs, while depression was not reported. Our review suggests that these AEs may have been influenced by biological mechanisms as well as the broader psychosocial context of the COVID-19 pandemic. Although this study had limitations, such as a primary focus on the BNT162b2 vaccine and an observational study design, it offered a systematic, multi-vaccine analysis that fills a critical gap in the existing literature. This review underscores the need for continued surveillance of psychiatric AEs and guides future research to investigate underlying mechanisms, identify risk factors, and inform clinical management.

Published: March 2024

Metal complexes, which, under physiologic conditions, show redox properties and are able to bind to DNA, are great tools to cleave the DNA chain. This aspect is of great importance for their use as antineoplastic drugs. We synthesized ligands derived from short-chain amino acids and from salicylaldehyde. The prepared ligands of the type of reduced Schiff bases were subsequently used for the preparation of copper(II) complexes. The aim of the study was in vitro testing of copper(II) complexes, where it was confirmed that they are capable of cleaving DNA. Their cytotoxic activity was also confirmed by the resazurin redox method on Saccharomyces cerevisiae based on preserved healthy mitochondrial function.
Athlete biological passport: longitudinal biomarkers and statistics in the fight against doping
Authors: Dragčević Dora , Pandžić Jakšić Vlatka , Jakšić Ozren
Published: March 2024

As novel substances, short time windows, and limits of detection increasingly challenge direct methods of doping detection in sports, indirect tools inevitably take a greater role in the fight against it. One such tool is the athlete biological passport (ABP) – a longitudinal profiling of the measured haematological and biochemical biomarkers, combined with calculated scores, against the background of epidemiological data crucial for doping detection. In both of its modules, haematological and steroidal, ABP parameters are analysed with the Bayesian adaptive model, which individualises reference and cut-off values to improve its sensitivity. It takes into account the confounding factors with proven and potential influence on the biomarkers, such as race and altitude exposure. The ABP has already changed the fight against doping, but its importance will further grow with the new modules (e.g., endocrinological), parameters (e.g., plasma volume-independent parameters), and complementing indirect methods (e.g., transcriptomic).

This study aimed to assess the redox status and trace metal levels in 49 shoe industry workers (11 men and 38 women) occupationally exposed to a mixture of volatile organic compounds (VOCs), which includes aliphatic hydrocarbons, aromatic hydrocarbons, ketones, esters, ethers, and carboxylic acids. All measured VOCs were below the permitted occupational exposure limits. The control group included 50 unexposed participants (25 men and 25 women). The following plasma parameters were analysed: superoxide anion (O2
•−), advanced oxidation protein products (AOPP), total oxidative status (TOS), prooxidant-antioxidant balance (PAB), oxidative stress index (OSI), superoxide dismutase (SOD) and paraoxonase-1 (PON1) enzyme activity, total SH group content (SHG), and total antioxidant status (TAS). Trace metal levels (copper, zinc, iron, magnesium, and manganese) were analysed in whole blood. All oxidative stress and antioxidative defence parameters were higher in the exposed workers than controls, except for PON1 activity. Higher Fe, Mg, and Zn, and lower Cu were observed in the exposed vs control men, while the exposed women had higher Fe and lower Mg, Zn, and Cu than their controls. Our findings confirm that combined exposure to a mixture of VOCs, even at permitted levels, may result in additive or synergistic adverse health effects and related disorders. This raises concern about current risk assessments, which mainly rely on the effects of individual chemicals, and calls for risk assessment approaches that can explain combined exposure to multiple chemicals.

Human exposure to plastic particles has raised great concern among all relevant stakeholders involved in the protection of human health due to the contamination of the food chain, surface waters, and even drinking water as well as due to their persistence and bioaccumulation. Now more than ever, it is critical that we understand the biological fate of plastics and their interaction with different biological systems. Because of the ubiquity of plastic materials in the environment and their toxic potential, it is imperative to gain reliable, regulatory-relevant, science-based data on the effects of plastic micro- and nanoparticles (PMNPs) on human health in order to implement reliable risk assessment and management strategies in the circular economy of plastics. This review presents current knowledge of human-relevant PMNP exposure doses, pathways, and toxic effects. It addresses difficulties in properly assessing plastic exposure and current knowledge gaps and proposes steps that can be taken to underpin health risk perception, assessment, and mitigation through rigorous science-based evidence. Based on the existing scientific data on PMNP adverse health effects, this review brings recommendations on the development of PMNP-specific adverse outcome pathways (AOPs) following the AOP Users’ Handbook of the Organisation for Economic Cooperation and Development (OECD).
Beyond the Initial Export Boost: The Erosion of Trade Agreement Benefits
Authors: Ronen Eyal
Published: March 2024

Preferential trade agreements (PTAs) are widely acclaimed for their potential to mitigate market imperfections and expand export opportunities. However, in changing economic circumstances, these beneficial effects may only endure for a while and often gradually fade, affecting industries unevenly. This study delves into this overlooked phenomenon by exploring Poland‘s export performance in the Western Balkan (WB) region, where the implementation of Stabilization and Association Agreements (SAAs) has evidently generated export growth, primarily driven by tariff reductions, though these gains were manifested disproportionally across sectors. Employing survival analysis, the study validates the positive influence of SAAs on Polish export competitiveness within the WBs while uncovering its temporal erosion and sectoral discrepancies. On average, a 51% and 84% decline in Polish export competitiveness to WBs is observed after 5 and 10 years, respectively. Moreover, a unique dataset on non-tariff measures (NTMs) is employed to identify specific sectors encountering significant NTMs contributing to the reported diverse export patterns. These insights highlight the need for policies that acknowledge the diminishing benefits of trade agreements and mitigate the trade imbalances caused by NTMs.
A Target Recognition Method of Small Sample Based on RCS Data
Authors: Ma Ruocheng , Liu Haoyang , Yu Jun , Hu Zhiyi
Published: March 2024

During the training of target recognition models based on Radar Cross Section (RCS) data, a persistent challenge arises in sampling due to the inherent difficulty in acquiring a sufficient number of samples. This scarcity of data poses a significant impediment to the effective training of models, resulting in diminished accuracy in target recognition. To address this issue, this article proposes a target classification method based on RCS data under small sample conditions. The approach adopts the fundamental concept of Model-Agnostic Meta-Learning (MAML) to train the target recognition model, enhancing the structure of MAML model. An hourglass-shaped convolution layer is introduced to the input layer, with an additional convolution layer preceding the output layer, and a switch to a central loss function. To substantiate the efficacy of the improved MAML model, comprehensive comparative analyses are conducted with benchmark models, including MAML, ResNet 18-layers, Long Short-Term Memory (LSTM), among others. Experimental results conclusively demonstrate the superior performance of the refined MAML model in target recognition under conditions of limited samples, attaining an average prediction accuracy of 85.62%. This signifies a noteworthy 5-percentage-point improvement compared to the baseline model prior to the introduced enhancements.
Indoor Robot SLAM with Multi-Sensor Fusion
Authors: He Jionglin , Fang Jiaxiang , Xu Shuping , Yang Dingzhe
Published: March 2024

In order to solve the problem of large positioning error and incomplete mapping of SLAM based on two-dimensional lidar in indoor environment, a multi-sensor fusion SLAM algorithm for indoor robots was proposed. Aiming at the mismatch problem of the traditional ICP algorithm in the front end of the lidar SLAM, the algorithm adopts the PL-ICP algorithm that is more suitable for the indoor environment, and uses the extended Kalman filter to fuse the wheel odometer and IMU to provide the initial motion estimation value. Then, during the mapping phase, the pseudo 2D laser data converted from the 3D point cloud data obtained by the depth camera is fused with the data obtained from the 2D lidar to compensate for the lack of vertical field of view in the 2D lidar mapping. The final experimental results show that the fusion odometer data has improved the positioning accuracy by at least 33% compared to a single wheeled odometer, providing a higher initial iteration value for the PL-ICP algorithm. At the same time, fusion mapping compensates for the shortcomings of a single two-dimensional lidar mapping, and constructs an environmental map with more complete environmental information.

Published: March 2024

This study introduces a technique for facial recognition according to capsule networks. The system utilizes the advantages of capsule networks to model the face features in the image hierarchically, and realizes the efficient recognition of faces. First of all, we know the difference between the capsule network and the convolutional neural network through the study of the operating principle and the structure of the capsule network. Secondly, the Capsule Network is realized through deep research on the algorithm for dynamic routing and the internal operating principle of the capsule. Finally, by conducting experiments on the face dataset and optimizing it with the Adam optimization algorithm as well as the boundary loss and reconstruction loss, the capsule network is promoted to learn more robust feature representations to obtain better face recognition results. The experiments show that the face recognition system based on capsule network can reach 93.5% correct rate of evaluation on WebFace dataset, which achieves a high recognition accuracy. The final results demonstrate the feasibility and effectiveness of capsule networks for face recognition.

Purpose: The purpose of this study is to identify the evolution of Halal Production in relation to Halal authentication techniques from time to time, such as sources, document types, journal names, topic trends, and author collaborations. Bibliometric analysis was used to analyze 200 articles published between 2013 and 2023. Halal Production is the main keyword used in the article title, abstract, and keywords to get the metadata retrieved from the Scopus database in May 2023, where most of the articles were written in English.
 
Theoretical framework: This study combines the results of the analysis of several articles published in Scopus data using vosviewes with halal variables because it avoids the rules listed in the Qur'an because Halal means being free from all forms of substances that have been forbidden in Islam, namely: carrion, blood, pork, and slaughtered animals do not mention the name of Allah (QS. Al-Maidah: 3).
 
Methods: This study method uses The tools used in this bibliometric analysis are Harzing's Publish or Perish to extract data from the Scopus database and VoS Viewer for data visualization and are then used for citation and metric analysis.
 
Results and Conclusions: The results showed that most of the articles related to Halal Production In Relation To Halal Authentication With Maximum Maslahah were published in scientific journals, compared to other publication outlets. Related articles published in scientific journals get the highest citation compared to others. Based on network visualization, the most dominant terms (often appearing) are production and halal food. And from this analysis it was found that several keyword trends could be used as findings for further research. Like halal production with its relation to halal authentication. When viewed from the overlay visualization, the topic of halal standards, production shows the latest trends in research related to Halal Production In Relation To Halal Authentication With Maximum Maslahah
 
Research implications: Research is important to use because for research needs further research related to halal used by Muslim or non-Muslim countries related to food health and other types of goods.
 
Originality/value: It is hoped that through this research Muslim countries can use halal variables as one of the indicators that input into food as eligibility for consumption as well as other goods that the goods avoid dirty goods.

Risks of international settlements of Russian organizations in the context of fragmentation of the international financial and economic space and ways to overcome them
Authors: NAVOI Anton V.
Published: March 2024

Subject. The article addresses the issue of building a new model of international trade and international settlements, enabling to overcome risks and minimize imbalances in relations with the rest of the world.
Objectives. The study aims to identify and assess the main risks of the current model of world economic relations of the Russian Federation, including the structure of international trade, the model of international settlements and the state of the domestic currency market.
Methods. I employ general scientific methods.
Results. Analysis of commodity and geographical composition of foreign trade helps conclude about significant risks of the formed model. They include low diversification of exports, dependence of the economy on foreign supplies of goods of high redistribution, and concentration of foreign trade activities in unfriendly jurisdictions. The risk picture is supplemented by the high share of currencies of unfriendly countries in settlements for the supply of export and import goods. The realization of these risks under the fragmentation of the international financial and economic space leads to partial isolation of the domestic currency market from the international segment, disorganization of the system of international settlements between Russian counterparties and foreign partners.
Conclusions. The risks of international settlements can be partially mitigated by the gradual equalization of bilateral trade balances of the Russian Federation with the main trading partners, the transition to mutual settlements in national currencies and the use of clearing schemes.

«СМЕРТЬ ЗАВЖДИ ЗБУДЖУЄ»: (ПОСТ)МОДЕРНА ПАТОПОЕТИКА РОМАНУ «ОСИНА ФАБРИКА» ІЄНА БЕНКСА
Authors: АКУЛОВА Надія
Published: March 2024

Анотація. Статтю присвячено вивченню поетики поведінкових розладів у романі «Осина фабрика» (1984) Ієна Бенкса, який пропонує читачеві майстерно виписану історію життя психопата зі спотвореною гендерною ідентичністю. Як засвідчує історіографічний аналіз проблеми, з таких позицій перший опублікований роман шотландського письменника розглянуто вперше. Специфіка предмета й мети дослідження зумовила його методологію, засновану на працях представників сучасного українського та західноєвропейського літературознавства, що досліджують естетику постмодернізму в ракурсі її зорієнтованості на маргінальність та інтересу до девіацій. Важливими для аналізу стали також розвідки, що сприяли уточненню уявлень про специфіку психопатологій, їхні ознаки та причини появи у членів суспільства. У процесі дослідження встановлено, що унікальною особливістю роману «Осина фабрика» Ієна Бенкса є суголосність стильовим тенденціям постмодернізму й водночас намагання письменника уникнути їх. Продемонстровано, що важливою ознакою патопоетики цього твору є поєднання гротескових ситуацій і чорного гумору зі справді трагічною історією душевного розладу особистості протагоніста. З’ясовано, що авторський задум реалізований не так на змістовому, як на формальному рівні твору. Зокрема зазначено, що концептуальні смисли транслюються Ієном Бенксом за допомогою специфічної композиційної організації роману, завдяки його особливій наративний структурі. Доведено, що основним засобом впливу на читача стала оповідна техніка письменника: оповідь у творі ведеться від імені протагоніста, і саме його химерний кут зору на події порушує автоматизм читацького сприймання, адже читач підсвідомо змушений співчувати жорстокому вбивці та психопату. Загалом роман «Осина фабрика» демонструє неперевершене вміння Ієна Бенкса задовольнити смаки як пересічного масового, так і інтелектуального читача.
АНАЛІЗ СУЧАСНИХ АНГЛОМОВНИХ КОМІКСІВ ТА ЇХ ТИПОЛОГІЯ

Анотація. У статті розглянуто сучасні англомовні комікси та їх типологію, а також історію становлення цього жанру. Стверджено, що він становить невід’ємну частину сучасної літератури й користується значною популярністю у читачів різного віку, зокрема в підлітків. Підтверджено, що комікси є за своєю суттю «мальованою історією» чи «розповіддю у картинках», яка об’єднує словесні та візуальні елементи й повідомляє про складне й серйозне просто, а саме за допомогою малюнків і мінімуму тексту. Такий спосіб подання інформації найбільш сприйнятливий і найменш вразливий. Встановлено, що численні дослідження засвідчують позитивний психологічний ефект від прочитання коміксу, а також констатують безболісне сприйняття та усвідомлення реальності читачами. Тож за допомогою графічних історій та створення певного образу персонажа можна здійснювати психологічний супровід і надавати постійну психоемоційну підтримку людям різного віку, що й зумовлює актуальність дослідження особливостей жанру коміксів. Відповідно мета статті полягає в аналізі історії походження коміксів і з’ясуванні їхнього впливу на соціальні проблеми суспільства. Зазвичай комікси різняться між собою формою та форматом. Відповідно виокремлюють щорічник або Annual, британський щорічник, щомісячні видання (Monthly), представлені серією або низкою серій, BD (Labandedessinee) (європейські комікси), вебкомікс та графічну новелу. Існує кілька підходів до класифікації коміксів залежно від їхньої форми, обсягу, стилю, жанру, сюжету тощо. Вони реалізуються в різних жанрах та притаманному їм стилі. Комікси як візуальний засіб передачі інформації успішно використовують у різних сферах, зокрема в навчанні, просвітницькій та профілактичній діяльності тощо. Показано, що вони відіграють неабияку терапевтичну роль у підтримці та збереженні ментального здоров’я, що є особливо актуальним для України, яка перебуває у стані війни.
