The article analyzes various variants of power transmission with galvanic isolation with respect to a high-voltage line to power a voltage sensor based on a system of galvanically coupled bodies. It is concluded that it is advisable to use wire-less energy transmission technology for these purposes. The parametric dependences of the main energy characteristics of the wireless energy transfer system with a serial topology are given, on the basis of which the parameters of the reso-nant circuit of the wireless energy transfer system have been calculated. Under the conditions of technical limitations, these parameters provide the maximum efficiency at a given distance between the transmitting and receiving coils. The influence of asymmetry of primary and secondary circuits on efficiency and transmission coefficient by load current of asymmetric system of wireless energy transfer with weak coupling has been investigated. An algorithm for calculating the resonant circuit parameters of the wireless power transmission system, providing maximum efficiency under technical constraints, has been proposed. The results of experimental studies of the proposed wireless power supply system are presented, confirming the correctness of the calculation and the subsequent possibility of using a wireless power supply system for a voltage sensor based on a system of galvanically coupled bodies.

The article considers the problem of modeling stationary physical fields at a given source distribution on the plane. Boundary value problems with boundary conditions of the first and second kind are formulated, the solution of which is sought using conjugate field potentials by the combined mesh-free methods of fundamental solutions and Monte Carlo. The fundamental solutions of the Laplace equation and their conjugate functions are used as basic functions for the approximate solution of boundary value problems. The peculiarities of applying the method of fundamental solu-tions in relation to boundary value problems with mixed boundary conditions are described in cases where the compu-tational domain is simply connected and multi-connected, bounded and unbounded. A numerical procedure for calcu-lating the field using the combined method of fundamental solutions and Monte Carlo is presented. When using the combined method, the solution of boundary value problems found at certain points of the computational domain by statistical tests using the sphere walk algorithm is used to set additional conditions when finding the decomposition co-efficients of an approximate solution in terms of basic functions in the form of fundamental solutions. The effective-ness of the developed approach to solving boundary value problems is demonstrated using the calculation example of the electromagnet field and the force acting on the anchor. By comparing the results obtained by the combined mesh-less method and by using the ELCUT program for modeling physical fields, it is shown that the method of fundamental solutions provides the necessary accuracy when the number of basic functions is several orders of magnitude less than the number of nodes used in the finite-element partitioning of the domain according to the algorithm implemented in ELCUT. It is found that the application of the method of fundamental solutions together with the Monte Carlo method allows to noticeably reduce the number of fundamental solutions used to find potentials while maintaining the neces-sary accuracy.
Types of addressing in Gavrila Derzhavin’s lyrical discourse
Authors:   Surgut State Pedagogical University, Larkovich Dmitry V.
Published: September 2024

The article deals with the specifics of communicative strategies and dialogical intentions of Derzhavin the lyricist. In the context of this scientific problem, the author of the article identifies five types of addressing (sacred, political, ideological, friendly, erotic), which determine the genre, intonation and thematic conditionality of Derzhavin's lyrical utterance and establish the nature of the relationship between the subject of speech and its addressee. Sacred addressing in Derzhavin's lyrics is carried out in the speech situation of the dialogue of the lyrical subject with the Creator, who acts as an invisible, but quite tangible Interlocutor, embodied in his creation. The subjective activity of Derzhavin's lyrical utterance is stimulated by the feeling of direct involvement in the active subjectivity of the Divine Addressee, the comprehension of whose essence opens up the possibility for the lyrical subject to comprehend himself. Political addressing is actualized in situations where Derzhavin's lyrical hero addresses royal persons and statesmen. Formally, this type of addressing fits into the odic genre tradition and serves as a means of poetic declaration of the author's civic position. However, in Derzhavin, this stable rhetorical model takes on the character of personally engaged communication, which implies a high degree of intimacy in the relationship between the sender and the addressee, which is especially pronounced in poems dedicated to Catherine II. Ideological addressing is practised by Derzhavin in those cases when the poet pursues the goal of a public discussion of issues of ethical, epistemological or aesthetic content. From the point of view of referential attitudes, a communicative strategy of this kind of addressing can be polemical, declarative (manifestation) or heuristic. Friendly addressing is mainly inherent in poems written in the genre of a friendly message. In lyrical works of this type, along with the main subject of speech, another subject-object instance (addressee) often appears, as a result of which a situation of value plurality arises, in the dialectical unity of which the author's value position is determined. Poems containing erotic addressing are purely monologue in terms of the structure of speech constructions and masked in terms of the nature of subjectivity. This type of addressing develops from the expression of rhetorically conditional forms of love experience, oriented to the tradition of Alexander Sumarokov's poetic school, to personally engaged subjective statements, often marked by features of the author's selfirony. The presented typology of addressing in Derzhavin's lyrics demonstrates a wide range of communicative strategies of the poet, striving to establish a truly dialogic relationship with his reader. The author declares no conflicts of interests.
“May stagings be cursed now and forever”: Mikhail Bulgakov as the so-called author of War and Peace
Authors:   Novosibirsk State Pedagogical University, Kozlov Alexey E.
Published: September 2024

The article investigates the movement of the text of the staging of Leo Tolstoy's War and Peace (written by Mikhail Bulgakov in the early 1930s) in the aspect of genetic criticism. Particular attention is paid to the latent polyphony of Tolstoy's novel, revealed in Bulgakov's manuscripts and preparatory materials. According to the stated hypothesis, Bulgakov's “tailor's work” is explained by the “resistance of the material”: the monolithic structures of the Russian epic novel displayed amazing stability at an attempt of intermedial translation. The article analyzes the key techniques used by the playwright: the exteriorization of internal speech, the re-distribution of the words of the Author and the words of the Hero, the inclusion of the figure of the Reciter. The latter technique, related to the innovative school of Vladimir Nemirovich-Danchenko, transpires to be the key in the style of the author's intention: The Reciter in the work becomes not only the embodiment of the author's word, but also a translator, a way of verbalizing the inner voice, a key ethical and axiological instance. The analysis of the manuscripts and preparatory materials allows us to raise the question of the inclusion of such quasi-authorial materials in the collected works of the writer. Despite the noted innovation, it can be stated that, instead of the possibility of intensive exchange with the plot of the original work, the opposite extensive mechanism of routinisation worked - the form of the text's organization defeated the potential semantic energy. While working on the staging, Bulgakov apparently “did not experience” Tolstoy's novel (see Zorin about Dilthey's conception of Erlebnis). In fact, Bulgakov's War and Peace is a scriptor's text in which the author, like Borges' Pierre Menard, acts as a copyist (see Zenkin about this conception). This probably explains the deliberate denial of the significance of the work Bulgakov carried out. It is curious that, in a letter to Yevgeny Zamyatin, Bulgakov noted fatigue from working on Tolstoy's novel. The purity of such a denial reveals the posture behind this statement and makes one recall the comment of Tolstoy himself, who, at the moment of irritation, described War and Peace as “verbose rubbish”. The question of value of Bulgakov's War and Peace is most acutely resolved in preparing and publishing the collected works of the writer. In the author's opinion, such unexperienced scriptor's texts, playing a significant role in the study of the writer's creative laboratory, at the same time constitute the periphery of his literary heritage. And their acquisition in the format of an electronic digitized archive in this respect is fully justified (see http://bulgakov.literature-archive.ru/ru), which cannot be said about the academic collected works of the writer. The author declares no conflicts of interests.
Impact of cadmium on photosynthetic pigments, root structure, and nutrient concentrations in bean (Phaseolus vulgaris L.) plants
Authors: Gutiérrez-Martínez Paulina Beatriz , Ramírez-Hernández Blanca Catalina , Maldonado-Villegas Marcela Mariel
Published: September 2024

Cadmium (Cd) is a contaminant that causes significant damage to organisms. In plants, it results in growth delay, alters photosynthetic function, and affects nutrient concentrations. This study aimed to evaluate the impact of Cd (0, 0,25, 0,50, and 1 µM) on chlorophyll content, structural damage to the root, and the absorption and translocation of nutrients (Ca, K, Mg, Mn, Fe, and Zn) in Phaseolus vulgaris var. Opus plants. An increase in chlorophyll a was observed at Cd concentrations of 0.25 and 1 µM. Chlorophyll b increased across all Cd treatments, while carotenoid content decreased in all treatments. The roots exhibited structural damage as Cd concentrations increased. For nutrients, Ca, Mg, Mn, and Zn in leaves, and K in stems, increased with higher Cd doses. Conversely, K in roots decreased with higher Cd concentrations, and Fe decreased compared to the control in all evaluated organs. Our results suggest that Cd stress at low concentrations stimulates chlorophyll synthesis and that varying Cd concentrations induce synergistic and antagonistic effects in different organs of P. vulgaris, leading to nutritional disorders. Given the global importance of this crop, studying the molecular mechanisms and membrane transporters in P. vulgaris roots exposed to Cd is crucial for enhancing its resistance to Cd.

The valorization and use of lignocellulosic biomass from food processing to obtain value-added products is crucial to improve sustainability and reduce waste management costs. This potential for cost reduction is a reason for optimism, as it allows agro-industrial waste to be transformed into valuable resources, contributing to the circular economy. This study focused on the compositional and structural characterization of eleven types of lignocellulosic biomass (LCB) to evaluate their potential in producing nanopolysaccharides and polyhydroxyalkanoates. Parameters such as humidity, ash, proteins, extractives, structural carbohydrates, and lignin were analyzed in passion fruit peels, artichoke bracts, asparagus peels, lemon peels, orange peels, avocado seed, potato peels, cassava peels, sugar cane bagasse, rice husk, and rice straw. The results showed that fruit peels and other waste had a high extractive content (28.05%), while the content of lignin and structural carbohydrates varied between 69.66% and 30.53% and 22.2% and 8.84%, respectively. In addition to the characterization, this BLC's potential for producing biopolymers was explored, highlighting its relevance in various industries such as food and materials engineering. These findings underline the importance of using local natural resources sustainably, opening new opportunities to develop innovative applications such as pickering emulsions, biodegradable packaging, aerogels, hydrogels, and functional foods. These applications represent promising areas for future research and technological development.

Published: September 2024

This protocol describes the steps for imaging dendritic calcium transients evoked by backprogating action potentials. 2-photon imaging was performed using a 2-photon laser scanning microscopy system, custom-built on a BX51WI microscope (Olympus). A Ti:Sapphire laser (Chameleon Ultra I; Coherent) was tuned to emit pulsed excitation at 920 nm and scanned using a pair of X-Y galvanometer mirrors (6215, Cambridge Technology). Emitted fluorescence was collected through a water-immersion objective (60X, Olympus), a dichroic mirror (T700LPXXR, Chroma) and filters (ET680sp and ET525/50 m-2P, Chroma), and was detected using a GaAsP photomultiplier tube (PMT, H10770PA-40, Hamamatsu). A current preamplifier (SR570, Stanford Research Systems) was used to convert the output to voltage, which was then digitized by a data acquisition card (PCI-6110, National Instruments).

Authors: Lei Xue , Lu Ningyun , Jiang Bin , Wang Cunsong , Chen Chuang
Published: September 2024

With the advance of industrial systems, the online equipment fault diagnosis has encountered many challenges such as data drift and data imbalance under varying operating conditions, thus making stable and accurate diagnosis increasingly critical. Considering the above issues, a multi-scale attention mechanism diagnosis method with adaptive model that can be updated based on deep learning has been proposed. The method is composed of four main steps: training the multi-scale offline diagnosis model, transferring the parameters of the offline model, assessing the degree of data drifting, and adaptively updating the diagnostic model. A data balance strategy with adaptive weight balances both inter-class and intra-class data. The method updates the diagnostic model flexibly according to online data status, to reduce the impact of data drifting. The method was verified on a bearing test rig, which can reproduce the common bearing faults under variable working conditions. The experimental results have shown that the proposed method can accurately and reliably identify the bearing faults.

Authors: Kowsalya P. , Vijayalakshmi D.
Published: September 2024

Let $G=\{V(G), E(G)\}$ be a simple connected graph with diameter $d(G)$ and $k$ be a positive integer. A radio $k$-coloring of a graph is a proper node coloring that is an assignment $f$ of positive integers to the nodes of $G$ such that $|f(x)-f(y)| \geq k+1-d(x, y)$, where $x$ and $y$ are two distinct nodes, and $d(x, y)$ is the length between $x$ and $y$. The maximum color assigned to some node of $f(V(G))$ is called the span of $f$ and it is indicated by $\operatorname{span}(f)$. The least span over all radio $k$-coloring of $G$ is the radio $k$-chromatic number of $G$ and it is indicated by $r c_{\hbar}(G)$. In this paper, we investigate the radio $k$-chromatic number for the triple star graph $K_{1, n, n, n}$ and its middle graph $M\left(K_{1, n, n, n}\right)$, central graph $C\left(K_{1, n, n, n}\right)$, total graph $T\left(K_{1, n, n, n}\right)$ and line graph $L\left(K_{1, n, n, n}\right)$.
CLIP THINKING AS A DIDACTIC CHALLENGE IN THE CONTEXT OF TEACHING LATIN TO MEDICAL STUDENTS
Authors:   Bogomolets National Medical University, Kyiv, Ukraine, Chernenko Nina Anatoliyivna
Published: September 2024

The article examines the key features of clip thinking in modern education, highlighting its negative aspects, such as fragmentation in perception and information processing, as well as its advantages over conceptual thinking. It has been found that clip thinking, as a cognitive trait of contemporary students, significantly affects the mental activities of medical students studying Latin. The methodology of language teaching is constantly evolving, adapting to the rapid development of technology and information. The article traces the history of teaching Latin in European countries and Ukraine, seeking optimal methodological techniques to enhance traditional Latin study methods. Through theoretical and empirical research using descriptive, analytical methods, synthesis, comparison, and organized observation, it has been found that the traditional grammar-translation method for studying Latin can be effectively supplemented with virtual interactive learning methods. These methods address cognitive challenges associated with clip thinking, such as issues with attention and memorizing grammatical and lexical material. The use of interactive applications, including gamification, is proposed to facilitate the assimilation of educational information.

The article theoretically substantiates the linguistic and didactic strategy of the video course “Ukraine: History and Modernity,” developed at the Department of Ukrainian Philology for Foreign Citizens. It outlines the potential of this course in enhancing students’ foreign language communicative competence. Definitions and classifications of video materials for language learning are provided, along with criteria for selecting educational video content based on language content, quality, and relevance. The educational potential of authentic video materials is discussed, highlighting their effectiveness as a modern tool for foreign language teaching. Such materials are noted to boost student motivation, have emotional and intellectual impacts, and offer unique opportunities to learn both the language and culture, including the ethnopsychological characteristics of the people. The use of videos is emphasized for facilitating listening skills and promoting both visual and linguistic clarity through the reinforcement of standard language patterns. Various methods for incorporating video materials into foreign language classes are described. The article also details the author’s video course for foreign students, which includes thematically and stylistically diverse materials such as short videos, animated films, and full-length feature films. These materials aim to develop students’ listening and general communication skills, expand their vocabulary, and acquaint them with the history and culture of Ukraine. The stages of video material processing are modeled: pre-viewing to address semantic and linguistic challenges, viewing to check understanding and activate spoken language skills, and post-viewing to develop oral communication skills. Various types of tasks are proposed. An illustrative practical exercise set based on Channel 24’s “Viktor Glushkov” video is presented.
Impact of pectus excavatum deformity on the cardiopulmonary function: a literature review
Authors: Khodorovskaya Alina М. , Ryzhikov Dmitry V. , Dolgiev Bahauddin H.
Published: October 2024

BACKGROUND: Pectus excavatum deformity is the most common chest wall malformation. Currently, surgeons and researchers of this problem have no consensus on whether pectus excavatum is a purely aesthetic problem or whether pectus excavatum disturbs the function of the cardiopulmonary system.
AIM: To analyze publications on the effect of pectus excavatum on the cardiorespiratory system and the functional features of the heart and lung after thoracoplasty in patients with pectus excavatum.
MATERIALS AND METHODS: Data were searched in the scientific databases PubMed, Google Scholar, Cochrane Library, Crossref, and eLibrary without language limitation. In this article, the method of analysis and synthesis of information was used. Most of the studies included in the analysis were published in the last 20 years.
RESULTS: In patients with pectus excavatum, severity of cardiorespiratory dysfunction depends on the degree of chest deformity. According to obtained data, the pulmonary function test in patients with pectus excavatum in the majority of cases revealed restrictive pattern (formed vital capacity 80% of the norm, with normal ratio of forced expiratory volume in 1 minute to forced lung capacity). In most cases, echocardiography showed compression of the right heart chambers. Comparative analysis of the pre- and postoperative study of cardiorespiratory system in most cases indicated improvement and adaptation of the cardiopulmonary system to stress after surgical intervention.
CONCLUSIONS: Funnel chest is an aesthetic problem wherein a severe degree of deformity leads to impaired respiratory mechanics and dysfunction of the cardiovascular system. Surgical restoration of the volume of the retrosternal space allows improvement of the functional capabilities of the heart and lungs.

Authors: Essiam Sheila Ama , Ocloo James , Ofori Kwame
Published: September 2024

Background: Stakeholders of education are concerned about how factors such as single parenting are negatively affecting the students of Ghana, especially Nkanfoa Methodist Primary School in the Cape Coast Metropolis. The study set out to investigate the effects of single parenting on students’ academic performance at Nkanfoa Methodist Junior High School (JHS) in the Cape Coast Metropolis.
Methods: Descriptive research design was adopted for the study. The study employed a mixed-method approach through the use of self-developed questionnaires. Eighty students selected through a proportionate stratified sampling participated in this study. Data was analysed using descriptives and independent sample t tests.
Results: The results from the study revealed that students from two-parent homes performed better than those from single-parent homes. In addition, more students were affected by parental status by way of their fees not being paid on time, all their books not being provided to aid their academic work, and their parents not reminding them to learn. Furthermore, the majority of students from single-parent homes faced challenges such as verbal abuse from parents, and their parents being more concerned with their jobs than them among others.
Conclusions: It was recommended that school authorities and community leaders should work together to organize seminars and workshops for parents to empower them to take active roles in the academic work of their children.

Authors: Tun Nyein Aye , Mon Khaing Lay , Hone San , Lat Tun Win , Win Hla Hla
Published: September 2024

Background: Increased work stress, decreased job satisfaction and increased turnover intention impair the quality of healthcare services. This study aimed to determine the current status of turnover intention, to assess the effects of work stress, workplace violence, and job satisfaction on turnover intention, and examine the mediation role of job satisfaction between associated factors and turnover intention.
Methods: A cross-sectional analytical study was conducted in 2023. A total of 189 midwives (MW) and 205 public health supervisors (PHS II) participated. The relationships between work stress, workplace violence, job satisfaction on turnover intention were assessed using the Pearson correlation coefficient. Path analysis was performed to study the mediation role of job satisfaction.
Results: Among the participants, (60.2%) had a high level of turnover intention, (7.4%) experienced high work stress and (23.9%) were dissatisfied with their jobs. Ninety-nine participants (25.13%) had been exposed to any type of workplace violence (physical, verbal, bullying or sexual harassment). Work stress was significantly positively correlated with turnover intention (r=0.4), while workplace violence had no significant correlation (r=0.006). Job satisfaction was significantly negatively correlated with turnover intention (r=-0.530). Job satisfaction had mediation role between work stress and turnover intention, but it had no mediation role between workplace violence and turnover intention.
Conclusions: High turnover intention among participants is significantly associated with work stress and job satisfaction. An urgent and effective strategy is required to retain them.

Authors: Yeşilyurt Eylül , Altunkürek Şeyma Z.
Published: September 2024

Background: Skin cancer is a serious disease that is now widespread, affecting many people globally. It has a high mortality rate both worldwide and in Türkiye. This study investigated the effect of educating parents of secondary school students about skin cancer, skin self-examination (SSE), and sun protection behaviors on their children’s sun protection behaviors.
Methods: The study was conducted as a randomized controlled experimental study. The study sample consisted of 240 parents. Data were collected using an introductory information form, the skin cancer and sun knowledge scale (SCSKS), and the parental sun protection scale (PSPS).
Results: After training, the number of parents in the experimental group who applied SSE to their children increased to 59.2% (p<0.001). However, this rate was determined as 10.8% in the control group. Significant increases were observed in the total SCSKS score (16.02±3.64) and the sun protection (4.63±1.28), tanning (7.45±1.98), and skin cancer prevention (1.54±0.59) subdimensions in intervention group (p<0.001). After training, a positive and significant difference was observed in the outcome for PSPS self-efficacy subdimension as well as for the sun avoidance scale- product usage expectations subdimension in the experimental group (p<0.05).
Conclusions: There was also an increase in the number of parents performing SSE on their children. Parents have an impact on their children’s health. Therefore, educating parents is critical both in terms of their own sun protection behaviors and for those of their children. It is recommended that intervention studies be conducted with larger sample groups.

Authors: Shashikala Narayanappa , Kathari Bhagyashree
Published: September 2024

Background: Menstrual hygiene is a noteworthy public health issue that is linked to gender inequality, discriminatory, social norms, cultural taboos, poverty and lack of basic services like toilets and sanitary products, restricting women’s participation in community life. Thus understanding the knowledge of the future healthcare providers is imperative.
Methods: A cross sectional study was conducted among 290 female medical undergraduate students during the period of July and August 2023. The data was obtained with the pre-structured questionnaire through Google forms.
Results: Among 290 female medical undergraduates, 93.1% of students had received education about menstruation, 83.4% shared this experience with their mothers. Nearly 42.8% of them could not attend to their daily work and avoided college during menstruation because of menstrual symptoms such as dysmenorrhea, nausea, vomiting and giddiness. However, 94.8% are willing to seek help from a health care provider for their menstrual problems.
Conclusions: Menstrual health education should address the areas where they lack knowledge, attitudes, and beliefs and identify the socio-cultural and environmental barriers to improve menstrual hygiene management (MHM) programme.

Background: COVID-19 pandemic impacted all aspects of life in one way or the other may it be physical, mental or spiritual. The consequences following COVID-19 had a significant effect on quality of life (QOL) of all the people irrespective of caste, creed or religion.
Methods: The present study was conducted among health care professionals (HCPs) in a tertiary care hospital in Jammu city of UT of Jammu and Kashmir. To measure the mental health, DASS-21 scale was used to ascertain the prevalence of depression, anxiety and stress. To assess the quality of life, the tool used was World Health Organisation quality of life scale (WHO QOL- BREF).
Results: The data thus collected was analysed and chi square test was used as a test of significance. A total of 250 health care professionals were assessed and prevalence of depression, anxiety and stress was found to be 51.2%, 18% and 45.2% respectively. Gender was significantly associated with anxiety (p<0.05) while education levels had a statistically significant associated with anxiety and stress (p<0.05). All domains of QOL were found to be on higher side among male health care professionals and respondents living in urban areas. There was a statistically significant association between QOL and level of education (p<0.05).
Conclusions: The study has demonstrated that COVID-19 was negatively related to health care professionals’ mental health and QOL. In this context authors recommend targeted interventions to ameliorate both mental health as well as QOL.

Published: September 2024

Background: The World Health Organization defines vaccine hesitancy as a “delay in acceptance or refusal of safe vaccines despite availability of vaccine services”. While pregnancy does not inherently increase susceptibility to COVID-19, pregnant women face higher risks of severe illness if infected. Misconceptions during the crucial antenatal care period contribute to vaccine hesitancy. This study aimed to assess COVID-19 vaccine hesitancy among pregnant women in Sagar, Madhya Pradesh.
Methods: A mixed-method study was conducted using multistage random sampling. The study involved 70 unvaccinated pregnant women from the field practice area of Polyclinic Chameli Chowk and in-depth interviews with 17 key informants, including district immunization officers, vaccination officers, and health care workers. Inclusion criteria were unvaccinated pregnant women under 50 years, willing to participate, and without contraindications for COVID-19 vaccination. Data collection tools included a pre-tested semi-structured questionnaire for quantitative data and a question guide for qualitative data.
Results: Among the 70 unvaccinated pregnant women, 49 (70%) were primigravida, and 21 (30%) were multigravida. A significant majority, 57 (81.3%), were unemployed (housewives). Vaccine hesitancy was identified in 66 (94.2%) women, while 4 (5.7%) were resistant to vaccination.
Conclusions: The study highlights the importance of communication from trusted sources, easy access to vaccines, and community engagement in addressing vaccine hesitancy among pregnant women. The findings suggest targeted interventions to reduce hesitancy and ensure timely mass immunization against COVID-19.

Published: September 2024

Background: Atopic dermatitis (AD) is a common inflammatory skin condition affecting infants globally, including in India. Its prevalence is rising, with formula-fed infants showing higher rates than breastfed ones. Breastfeeding provides numerous benefits, including optimal nutrition and immune protection. Although several studies have explored the link between breastfeeding and AD, the evidence is inconsistent. This study aims to assess the prevalence of AD among Indian infants in the Srikakulam region and examine the effect of exclusive breastfeeding (EBF) and formula feeding on AD rates.
Methods: This cross-sectional study used convenience sampling to collect data from 180 guardians of infants aged 0-6 months in the Srikakulam region, Andhra Pradesh, from April to June 2024. Data on demographics, feeding practices, and AD diagnoses confirmed by pediatricians were gathered through an electronic questionnaire. Analysis was done using SPSS V.21.0 with chi-square and correlation tests.
Results: Among the 180 infants, 72.2% had AD. A significant gender difference was observed, with 85 males and 45 females affected (p<0.05). Most AD cases were found in the 4-8 month age group. EBF was practiced in 30% of infants, while 70% were formula-fed. Formula-fed infants had more hospitalizations.
Conclusions: This study shows a high prevalence of AD in the Srikakulam region, with males more affected. EBF may offer protection against severe AD, emphasizing the need for public health efforts to promote EBF. Further research is needed to deepen understanding.
