Authors: Mikhailova D. S. , Mager S. N.
Published: October 2024

Among the diseases of young cattle, the most common are lesions of the gastrointestinal tract. Most often they are manifested by diarrhea, which leads to dehydration of the body and severe metabolic disorders. Often sick calves lose a lot of weight, and then lag behind in growth compared to healthy animals, cases of death are not uncommon. With such diseases, the microflora inhabiting the digestive tract is subject to great changes. At the same time, it is populated by pathogenic species whose vital activity complicates the course of the disease. We have studied the therapeutic effect of the use of phytometabiotic drug “Phytolizat Gastro” in gastrointestinal diseases in calves. For the study, experimental and control groups of black-and-white calves aged 10-14 days were formed by the method of analogues. All the calves studied had a clinical sign of gastrointestinal tract damage - diarrhea. According to the results of the study, the effect of the drug on the body was established. Blood counts vary in intervals close to the average values of norms. According to the results of the study, the recovery of calves of the experimental group in a shorter time, greater preservation of body weight during recovery and further increase in calves of the experimental group (by 85 g) compared to calves of the control group was established. Microbiota studies have shown that the amount of Lactobacillus spp. the calves of the experimental group decreased by 8.5% less compared to the control group, and the amount of Bifidobacterium spp. the calves of the experimental group increased by 48%. At the same time, the total number of lacto- and bifidobacteria prevails in calves of the experimental group, which indicates a positive effect of the studied drug on the microflora of the gastrointestinal tract of calves.
The results of research on technological indicators in the experimental module for growing broiler chickens
Authors: Plaksin I. E. , Trifanov A. V.
Published: October 2024

Russia ranks fifth in the world in poultry meat production. In the period from 2010 to 2021, the volume of production of this type of product increased by 1.77 times, which in physical terms is 2,190 thousand tons. The largest volume of poultry meat production, 89.7%, falls on the meat of broiler chickens. This indicator is justified by consumer preferences of the retail market, a low feed conversion rate, a high level of automation of production processes, as well as the possibility of up to 8 production cycles per year. The main share, amounting to 93%, of broiler chicken meat production is accounted for by large agricultural enterprises. Households of the population and peasant farms account for 7% of production. This result is observed due to the lack of technical and technological solutions for small-scale production, providing for the use of automation of production processes, which leads to a decrease in productivity and an increase in poultry mortality. The combination of these factors increases the cost of finished products, making small-scale production uncompetitive. To solve this problem, a project has been developed and a prototype of a technological module for fattening broiler chickens has been manufactured. The production capacity of the module is 2,800 broiler chickens per year. The module uses a cellular method of keeping poultry on a mesh flooring. As a result of the conducted studies, the feed conversion rate was 1.66, the cost of water was 3.4 liters, electricity was 3.22 kWh and labor was 0.051 people per kilogram of live weight. The obtained indicators are comparable with those of large poultry farms, which allows us to conclude that it is advisable to use technological modules at small poultry enterprises.

Published: October 2024

The urinary system of aquatic mammals plays an important role in maintaining the body’s homeostasis. Features in the structure and topography of the urinary organs are associated with the habitat and adaptation of the organism of aquatic animals to it. Interest in studying the features of the topography of organs and the structure of the organism as a whole, as well as the organs of urine formation and excretion in particular, is presented by the Baikal seal, given its freshwater lifestyle. The goal was to describe the species-specific features of the topography of the kidneys, ureters, bladder and urethra in male and female Baikal seals. The object of the study was both live individuals and carcasses of the Baikal seal (Phoca sibirica) aged from 1.5 to 3 years. The animals were examined at the Baikal Seal Aquarium LLC and the Irkutsk City Animal Disease Control Station. The cadaver material was collected under the program of the Russian Federal Agency for Fisheries, as well as research and development, experimental design and technological developments (R&D and R&D) from 2014, 2017, 2020. The study material was the organs of the urinary system: kidneys, ureters, bladder, urethra. The studies were carried out using various anatomical methods: autopsy of cadaver material with examination and fixation of syntopy, skeletotopy, holotopy and anatomical dissection, ultrasound diagnostics and multispiral computed tomography.

Authors: Terentyev S. S. , Pashkin A. V. , Burova E. I.
Published: October 2024

The aim of the study is to explore the ways of implementing digital technologies and modern technical solutions to ensure the population health of animals in the context of contemporary dairy farming. The paper discusses modern digital technical tools and automated processes in dairy farming facilitated by these tools. In the course of the study, the main tasks for successful digital transformation and ensuring the population health of animals in dairy farming were identified: searching for biomarkers of pathological and physiological states of animals, developing methods for determining found biomarkers, developing technical solutions for parameter registration and their implementation into production. At the moment, automatic systems for diagnosing the state of the animal’s body have been implemented using sound sensors, devices for determining the activity of the animal and the position of the body in space. Sensors for determining the electrical conductivity of milk make it possible to determine mastitis at the initial stage of the pathological process. Sensors for determining the concentration of hormones in milk make it possible to determine the period of the sexual cycle. ICS cameras allow you to determine areas of inflammation on the animal’s body. A modern 3-D camera system, combined with software, allows automatic measurement of animal body parameters on a daily basis. Thus, the implemented automated systems make it possible to reduce the time of human contact with an animal, which has a positive effect on the health of the animal. On the other hand, constant monitoring of important indicators of animal health allows timely detection of the onset of the disease. All of the above helps ensure population health on dairy farms.

DNA samples were isolated from whole blood taken from the jugular vein by an automatic extraction method. A real-time polymerase chain reaction was carried out to determine the polymorphism T586C of the GDF5 gene and C316G of the CAPN1 gene. In the studied herd of cattle, animals with the TT genotype predominate - 68.3 % of the population, the number of animals with the TC and CC genotypes is 21.7 % and 10 %. When studying the polymorphism of the CAPN1 gene, it was revealed that 23.3 % of the bulls of the studied population of Kalmyk cattle have the desired genotype CC, while the heterozygous genotype is present in 16.7 %, and the recessive genotype GG is present in 60 % of animals. The frequency of occurrence of the T allele of the GDF5 gene is 0.792, which exceeds the indicator of the C allele (0.208) by 58.2 %, the observed frequency of TT and CC genotypes exceeds the expected indicator by 5.6 and 5.7 %, respectively, while the indicator of the TC genotype is lower than the expected frequency by 11.2 %. The frequency of occurrence of the G allele (0.683) is 36.6 % higher than that of the C allele (0.317) of the CAPN1 gene. It is noted that the GG genotype with an index of 0.600 occurs with the highest frequency, while the CG genotype has a frequency of 0.167 (43.3 % less), the CC genotype – 0.233 (36.7 % less). The indicators of the observed frequency of the CC and GG genotypes are 13.3% higher than expected, the heterozygous genotype has an excess of the expected frequency by 26.6 %. Bulls with the TT genotype of the GDF5 gene outperformed their peers with the TC and CC genotypes in all measurements. When studying the live weight of Kalmyk cattle at the age of 15 months, a positive effect of the CC genotype of the CAPN1 gene was revealed. Thus, the group of animals with this genotype had the largest live weight and surpassed their peers with the genotypes CG (by 9.9 %) and GG (by 11.1 %).

This study was motivated by a significant increase in the number of complaints against the insurance industry, especially cases of claim default in 2018-2022. The purpose of the study was to measure and analyze the effectiveness of policyholder protection at AJB Bumiputera 1912 Medan through a regulatory effectiveness approach as variable x is the legal factor itself, law enforcement factors, facilities or facilities, community factors, and cultural factors. The research method is descriptive quantitative. Primary data was obtained from questionnaires and interviews. While secondary data is in the form of documentation studies, in the form of Articles of Association, general conditions of the policy, and laws and regulations that support the research. The results of the study on respondents’ responses show that all indicators of factors affecting the achievement of regulatory effectiveness have a fairly high percentage. However, it should be noted that the factors that produce ineffective percentages are 62.45% for law enforcement factors and 60.14% for community factors. Both factors are caused by the late presence of laws that clearly regulate the form of joint ventures, No. 4 of 2023 concerning Development and Strengthening of the Financial Sector (P2SK), where it is stated in article 53 paragraph 2e: “distribution of profits and losses on Joint Venture activities for members”.
Changing values of work (based on the materials from Russian and foreign publications)
Authors: Titarenko Larissa G. , Karapetyan Ruben V.
Published: October 2024

The sphere of work, which was previously central to Soviet and Russian sociology constantly covered in the Sociological Studies journal, is no longer so, although work remains an important subject of research in the conditions of the challenging digital transformation and growing uncertainty. Based on the analysis of domestic and foreign publications, the authors tried to identify current trends in the development of research that reflect global and regional changes in labor. Solving this problem allows the authors to show which problems attract the prime attention of scientists from different countries, and define the prospects for the future research. The authors show the discussion conducted by researchers on the topic of changing labor values. Particular attention is paid to how precarization is analyzed and the growth of the “meaninglessness” of labor is argued. A significant similarity of the identified problems in Russia and foreign countries is emphasized, regardless of the fact that they belong to different levels of socio-economic development, differ in work culture and other characteristics.
Politics in the journal “sotsiologicheskiye issledovaniya”: between ideology and episteme
Authors: Trofimova Irina N.
Published: October 2024

Each historical era is characterized by its own “episteme” – a general system of thinking and scientific theorizing. The episteme of politics in Russian sociology was formed in conditions of confrontation between ideology and scientific analysis, state patronage and academic freedom. The main stages are highlighted: 1) the first decade 1974–1984; 2) Perestroika 1985–1990; 3) 1990s; 4) 2000s. The journal «Sotsiologicheskiye issledovanya» is considered as a specific form of representation of professional knowledge and ways of knowing, determined by the current level of development of the discipline and the concept of the journal itself. The increasing complexity of the thematic structure, transdisciplinary approach, and the project-based and discussion-based nature of publications help overcome the epistemological uncertainty of politics.
Developmental trends of military sociology IN Russia (based on the analysis of publications in Sociological Studies, 2014–2023)
Authors: Karlova Ekaterina N.
Published: October 2024

The article presents an analysis of the state and prospects of military sociology in Russia, reflected in Sociological Studies for the period 2014–2023. The article is a logical continuation of the previously begun work on the analysis of military sociology institutionalization in Russia for the period 1974–2013. Thus, the results of the 50-year activity of the journal’s editorial board on the support and development of military sociology in Russia are summarized. Based on the thematic content analysis of publications and an analysis of quantitative and qualitative authorship characteristics, conclusions are drawn about a decrease in the number of studies of army problems in the last ten years, an increase in the number of materials on historical issues and prospects for the formation of the sociology of war as a new field of interdisciplinary knowledge. The authorship is being transformed to wards expanding regional and international diversity, reducing the number of authors representing the military department. Such problematic issues of military sociology development as the closed nature of research results in the military and the narrowing of traditional military sociological issues are stated. The potential of military sociology in the study of wars and armed conflicts remains unrealized, finding expression in the coverage of peripheral topics.

CAUCHY PROBLEM FOR ULTRA-PARABOLIC EQUATIONS OF KOLMOGOROV TYPE WITH BLOCK STRUCTURE
Authors: Dron' V. , Medynskyi I.
Published: October 2024

The investigation is devoted to ultra-parabolic equations which appear in Asian options problems. Unlike the European option, the payout of Asian derivative depends on the entire trajectory of the price value, not the final value only.

Among methods of researching of the Asian options, the one is to include dependent on the price trajectory variables in the state space. The expansion of the state space by including of dependent on the price trajectory variables transforms the path-dependent problem for the Asian option into an equivalent path-independent Markov problem. However, the increasing of the dimension usually leads to partial differential equations which are not uniformly parabolic. The class of these equations under some conditions is a generalization of the well-known degenerate parabolic A.N.Kolmogorov's equation of diffusion with inertia.

Mathematical models of the options have been studied in many works. It has been constructed so called L-type fundamental solutions for considered equations previously, some their properties have been established, the Cauchy problem has been researched. In current work, for the given equations we study the classical solutions of the Cauchy problem. For the coefficients of the equations we apply special Hölder conditions with respect to spatial variables. Under these conditions, we prove the wellposedness of the Cauchy problem in special weighed spaces, obtained integral presentation of classic solutions of the Cauchy problem for homogeneous equations. Classes of well-posedness of the Cauchy problem were described.

The results obtained in the work are realization of well-known Eidelman-Ivasyshen approach. Ones can be used to advanced studying of the Cauchy problem and boundary value problems for linear and quasi-linear degenerated parabolic equations, as well as in the theory of stochastic processes when studying Markov processes, the transition probability density of which is the fundamental solution of the Cauchy problem for these equations.
SOLUTIONS OF SOME INTEGRAL EQUATIONS OF THE SECOND KIND
Authors: Pasichnyk H.
Published: October 2024

The article examines the solutions of some integral equations of the second kind. Such equations arise when using Levi's method to construct a fundamental solution of the Cauchy problem for a degenerate equation of the Kolmogorov type. The equation may also contain a degeneracy on the initial hyperplane. The coefficients of this equation are bounded in the group of principal terms and ones are increasing functions in the group of lowest terms. The considered classes of kernels of integral equations make it possible to preserve the function that determines the growth of the coefficients of the parabolic equation when evaluating the resolvent. In the evalutions of the kernels of integral equations, there are evaluation functions that arise when constructing the corresponding fundamental solution, and fundamental solution of the Cauchy problem of the model equation with constant coefficients.
A MULTIPOINT BOUNDARY VALUE PROBLEM IN TIME FOR A $2B$-PARABOLIC EQUATION WITH DEGENERACY
Authors: Pukalskyy I. , Yashan B.
Published: October 2024

One of the most important issues in the general theory of differential equations with partial derivatives is establishing the solvability of boundary value problems. Among the boundary value problems for equations with partial derivatives, problems with nonlocal boundary conditions occupy an important place. Such interest in such problems is caused both by their rich practical application (the process of diffusion, moisture distortion in soils, plasma physics, etc.), and by the needs of the general theory of boundary value problems.

A general multipoint boundary value problem for nonuniformly $2b$-parabolic equations with degeneracy is studied. The coefficients of parabolic equations and boundary conditions allow power degeneracy of arbitrary order in terms of time variable and spatial variables at some set of points. To solve the given multipoint boundary value problem, solutions of problems with smooth coefficients in Hölder spaces with the appropriate norm are studied. With the help of interpolation inequalities and a priori estimates, estimates of the solution of auxiliary problems and their derivatives in special Gelder spaces are established. Using the theorems of Ross and Archel, a convergent sequence is distinguished from the compact sequence of solutions of the auxiliary problems, the limiting value of which is the solution of the multipoint boundary value problem in time for the $2b$-parabolic equation with degeneracy. Estimates of the solution of the given problem are established in Hölder spaces with power-law weights. The order of the power weight is determined by the order of features of the coefficients of the equations and the boundary conditions. With certain restrictions on the right-hand side of the equation and boundary conditions, an integral image of the given problem is obtained.
ON A BOUNDARY VALUE PROBLEM WITH INTEGRAL CONDITIONS FOR A SYSTEM OF DIFFERENTIAL EQUATIONS WITH MANY TRANSFORMED ARGUMENTS

Published: October 2024

A.M. Samoilenko's numerical-analytic method is well-known and effective research method of solvability and approximate construction of the solutions of various boundary value problems for systems of differential equations. The investigation of boundary value problems for new classes of systems of functional-differential equations by this method is still an actual problem. A boundary value problem for a system of differential equations with finite quantity of transformed arguments in the case of integral boundary conditions is considered at this paper. To investigate the existence and approximate construction of the solution of such boundary value problem it is proposed a traditional scheme of the numerical-analytic method with a determining equation, as well as a modified scheme without a determining equation. In the case of a traditional scheme it is constructed a recurrent sequence of functions that depend on parameter, each of which satisfies given boundary conditions. It is shown that under typical for numerical-analytic method assumptions, this sequence uniformly convergences to the limit function. It is established the value of the parameter at which the limit function will be an exact solution of the original boundary value problem. Approximate determining function and approximate determining equation put into consideration, and on the basis of them sufficient conditions for the solvability of this boundary value problem are obtained. The necessary conditions for the solvability of the considered boundary value problem and an estimation of the deviation of the approximate solution from the exact solution were also obtained. In the case of the modified scheme it is constructed a recurrent sequence of functions, each of which satisfies the specified boundary conditions. Under the typical for the numerical-analytic method assumptions, the uniform convergence of this sequence to the limit function, which is the exact solution of the considered boundary value problem, is proved. It is established the uniqueness of this solution and it is obtained an estimation of the deviation of the approximate solution from the exact solution. The proposed modified scheme of the numerical-analytic method is illustrated by concrete examples.

Nano zero valent iron (nZVI) has been utilized for environmental remediation and raw water treatment. The NaBH4 reductor, utilized in iron nanoparticle synthesis, yielded easily oxidized and agglomerated material. Using polyphenol as a bioreductor resulted in a more stable material. The purpose of this research is to synthesize and compare quality of nZVI utilizing NaBH4 (C-nZVI) to nZVI utilizing polyphenol from spent tea and the peel of pomegranate (G-nZVI) and determine the efficiency of pomegranate peel G-nZVI in reducing dissolved organic matter. The iron nanoparticle was synthesized by reducing FeCl3 salt in a water solvent. C-nZVI material was generated as a black powder, whereas G-nZVI materials were black flakes. The band gap energy values of these three materials indicate that they have reached the nanoscale. All three materials had entire nZVI unitary groups based on its FTIR spectrums. The X-ray diffractogram did not clearly show the core of the phase crystals. The G-nZVI from the peel of pomegranate had a greater distribution and mean material size than the spent tea G-nZVI. Both zeta potentials G-nZVI demonstrate that the materials were stable in the aqueous medium. After two hours of incubation, G-nZVI pomegranate peel at room temperature and dark conditions achieved an optimal dissolved organic matter breakdown rate of 98%.

DYNAMIC SIMULATION OF RUBBER PRODUCTION SYSTEMS USING SSM AND VENSIM APPROACHES
Authors: APRILIA HAFIZA
Published: October 2024

One of the contributors to the agricultural sector, particularly in the plantation sub-sector, is the rubber industry, which accounts for 38.54% of Indonesia's rubber exports. This opportunity arises from the fact that 85% of rubber producers are smallholder farmers, while the remaining share is owned by state and private enterprises. Makmurman is an individual rubber business owner based in South Sumatra Province, with a 4-hectare rubber plantation that directly sells raw rubber to collectors. The rapid advancement of technology in modern life has led to increased use of elastic materials, thereby driving higher demand for rubber, especially in the automotive industry. As a result, Makmurman has experienced a surge in demand for raw rubber from collectors. However, Makmurman has been unable to meet this demand, likely due to the many variables involved in the production process and the sale of raw rubber, which have created challenges. To address these issues, a root cause analysis is conducted to identify the appropriate solution using the soft system methodology approach. Additionally, data processing is carried out using Vensim software to model the rubber production system in a real-world scenario. The results include the development of causal loop diagrams and stock flow diagrams. The expected outcome is a dynamic system simulation with various scenarios, ultimately identifying the best scenario that ensures the highest availability of rubber for Makmurman to meet the demands of the rubber collectors.
On Linear Combinations of Harmonic Mappings Convex in the Horizontal Direction
Authors: Yaşar Elif
Published: October 2024

The process of creating univalent harmonic mappings which are not analytic is not simple or straightforward. One efficient method for constructing desired univalent harmonic maps is by taking the linear combination of two suitable harmonic maps. In this study, we take into account two harmonic, univalent, and convex in the horizontal direction mappings, which are horizontal shears of $\Psi_{m}(z)=\frac{1}{2i\sin \gamma_{m}}\log \left( \frac{ 1+ze^{i\gamma_{m}}}{%
1+ze^{-^{i\gamma_{m}}}}\right),$ and have dilatations $\omega _{1}(z)=z,$
$\omega _{2}(z)=\frac{z+b}{1+bz},$ $b\in (-1,1).$ We obtain sufficient conditions for the linear combination of these two harmonic mappings to be univalent and convex in the
horizontal direction. In addition, we provide an example to illustrate the
result graphically with the help of Maple.

Diffusion models have firmly established their excellence for image generation tasks, as evidenced by the success of renowned models such as DALL-E, Midjourney, and Stable Diffusion. This advanced development of diffusion models for visual content raises an interesting question: can diffusion models be adapted for audio generation tasks? In this study, we introduce a novel diffusion model architecture designed to generate mel spectrograms, visual representations of sound which can subsequently be converted into audible music. Given the exceptional capability of diffusion models to produce high-
quality images, their application to mel spectrogram generation is particularly promising. Our proposed diffusion model deviates minimally from the conventional architectures employed for visual content, making this research especially useful for examining the potential for cross-domain application between image and audio generation. The proposed model has been trained on a dataset consisting of over 186 hours of Lofi audio, offering the model diverse samples for generalized learning. However, a combination of research limitations led to subpar results, paving the way for further studies to build on this one.

Usher syndrome, a rare genetic disease affecting hearing and vision, is an autosomal recessive condition affecting 4 to 17 per 100,000 people and accounting for about 50 percent of hereditary deaf-blindness cases. Usher syndrome type II is caused by mutations of the USH2A gene, a 15.7 kb gene encoding the protein usherin, which localizes to photoreceptor cilium and cochlear hair cells. This subtype of Usher syndrome includes hearing loss from birth and progressive loss of vision, prompting retinitis pigmentosa (RP). Prime editing is a viable option for addressing USH2A mutations and restoring usherin expression and function. To begin, a HEK293T cell line needs to be established for subsequent testing of prime editors. Since prime editing to make the cell line was unsuccessful, homology-directed repair was done and successfully created a cell population with the mutation of interest (single base-pair deletion). Now that this cell population has been created, prime editors will be tested and optimized to address the mutation in a HEK293T cell line and potentially patient-derived induced pluripotent stem cells that are differentiated into photoreceptor precursor cells.

College students’s mental health has been declining, despite efforts by universities to improve outreach and programming. Though a variety of resources are available, students, especially those who experience marginalization, often do not engage with them. LGBTQ+ students in Florida, in particular, may face unique challenges. To understand marginalized college students’s mental health experiences, we conducted ten focus group interviews (N = 65) with students with various marginalized identities. Using Natural Language Processing (NLP) techniques, we conducted sentiment analysis with respect to students’s responses on interview questions (e.g., mental health needs, how needs are met/not met) among LGBTQ+ and other minority groups. Overall, LGBTQ+ students yielded a more negative sentiment than the other groups, with a marginally significant (at 0.1 level) difference suggested by Wilcoxon rank sum test. This project presents a novel approach to leveraging traditional qualitative methods and AI, provides deeper understanding of the mental-health-related needs of marginalized college students, and practical implications for prevention and intervention efforts to promote college students’s mental health.
Islam, Adat, and State: Examining the Phenomenon of Child Custody After Divorce in Padang Lawas Regency

Published: October 2024

This research is motivated by the phenomenon of childcare by fathers after divorce in Padang Lawas County. This phenomenon raises the interest of researchers to further examine child custody by fathers after divorce. The research method used is field research with a qualitative approach. Researchers collected primary data through interviews with traditional leaders and fathers caring for their children after divorce. The data obtained was then analyzed using descriptive analysis techniques, which involved collecting data through interviews and documentation and systematic data processing to describe and interpret existing phenomena. The results show that although customs in Padang Lawas County give custody to the father, it is essential to consider the provisions of the compilation of Islamic law and the broader principles of Islamic law. Child custody should focus on the best interests of the child, ensuring their physical, emotional, and mental development. Both parents have equal rights unless there are compelling reasons to the contrary, and they must work together to maintain the child's stability. Children have the right to adequate education and healthcare, as well as to maintain a good relationship with both parents, even if only one has primary custody.

The present study aims to determine the continuous care model's effect on cancer patients' self-efficacy. This randomized controlled trial study, employing a pre-test-post-test design with two groups, was conducted on cancer patients referred to chemotherapy centers in Gorgan, Iran, in 2020. The sampling method employed in this study was random allocation. Initially, the researcher compiled a list of eligible research units. Subsequently, using a simple random process, the research units were divided into 15 in the test group and 15 in the control group. The data collection tools in this research included demographic information (age, gender, marital status, education, occupation, and duration of illness) and the Chronic Disease Self-Efficacy Scales (CDSES). A total of 30 participants were divided into intervention and control groups. The average self-efficacy of the research units before the intervention was 144.8 (SD=11.53) in the test group and 147.97 (SD=11.97) in the control group. The independent t-test revealed no significant difference between the two groups before the intervention (P=0.47). Post-intervention, the average self-efficacy was 168.2 (SD=9.31) in the test group and 155.6 (SD=8.3) in the control group. The independent t-test showed a significant difference between the two groups (P=0.001). Consequently, it is recommended that nursing models and theories, particularly the continuous care model, be incorporated into structured and planned educational programs to provide nursing care, especially supportive care.

Published: October 2024

Technology in healthcare has grown exponentially in recent years [1]. Today, information and communication technologies have become widespread in healthcare systems worldwide. Since nurses comprise most of the healthcare workforce, they must possess sufficient skills to work in a technology-mediated environment [2]. The advancements in information technology over recent decades have provided significant opportunities for nurses to stay informed about patient conditions [3]. This has created new roles for nurses and enhanced their decision-making power in delivering nursing care [4]. Consequently, the trend of transformation in nursing informatics is expanding globally. The application of nursing informatics methods is on the rise [5], bringing about considerable changes in healthcare delivery [6]. Nursing informatics combines nursing processes, relevant information, and the management of nursing data along with other information processing systems. The primary goal of this discipline is to support health and well-being globally [7]. Proper utilization of informatics in nursing leads to cost reduction, increased awareness, and innovation and creativity among nurses [8].

The present study aims to determine the effect of Benson's sedation on the sleep quality of hospitalized elderly. This experimental study employed a simple random method to assign participants to two test groups of 34 individuals and a control group of 34 individuals. The Pittsburgh Sleep Quality Index (PSQI) was the data collection tool. In the test group, the researcher administered Benson's relaxation technique in four sessions, each lasting 10 minutes, under the supervision of a physician. The control group received only routine interventions. The collected data were analyzed using SPSS version 21, employing descriptive statistics (including tables, means, and standard deviations [SDs]) and inferential statistics (paired t-test and independent t-test). In the experimental group, the mean sleep quality score before the intervention was 9.48 (SD=3.52), which improved to 7.59 (SD=3.17) after the intervention. A paired t-test revealed a significant improvement in sleep quality within this group (P<0.01). In the control group, the mean sleep quality score was 9.21 (SD=3.21) before the intervention and 7.97 (SD=2.89) after the intervention; however, the paired t-test did not show a significant difference (P=0.6). The results of this study indicate that the Benson relaxation technique significantly improved the sleep quality of hospitalized patients. Consequently, this non-pharmacological, cost-effective intervention is a valuable addition to nursing care. Non-pharmacological methods, such as relaxation techniques, are recognized as effective adjunctive treatments in nursing practice.
