Authors: Yuliana Hajiar , Santoso Fajar Malik , Basuki Sofyan , Hidayat Muhammad Reza
Published: March 2023

Layanan 5G New Radio (NR) dapat memberikan keunggulan kecepatan data tinggi dan latensi rendah. Keberadaan teknologi 5G khususnya di Indonesia, sudah diimplementasikan oleh beberapa operator seluler di frekuensi 2300 MHz dan 1800 MHz. Akan tetapi, pengadaan jaringan 5G di Indonesia belum tersebar secara merata. Maka dari itu dibutuhkannya analisis perencanaan yang lebih rinci khususnya di area urban. Pada penelitian ini, dilakukan perencanaan jaringan 5G yang dibutuhkan di salah satu area urban di Pulau Jawa, yaitu Kota Cimahi, untuk frekuensi 2300 MHz dengan menggunakan metode analisis coverage planning. Model propagasi yang digunakan pada penelitian ini adalah 3GPP TR38.900. Berdasarkan analisis dan perhitungan yang dilakukan, didapatkan 26 site untuk area Kota Cimahi yang memiliki luas area sekitar 40,3 km². Selanjutnya, diatur penempatan letak site berdasarkan kondisi coverage di area tersebut dan juga berdasarkan persebaran jaringan 4G yang sebelumnya sudah ada di area tersebut, karena perencanaan 5G yang digunakan adalah tipe 5G Non-Standalone. Berdasarkan hasil analisis coverage yang dilakukan didapatkan kondisi level sinyal Synchronization Signal Reference Signal Received Power (SS-RSRP) diatas -90 dBm mencapai 27,3% dari keseluruhan luas area. Hal ini menunjukkan bahwa perencanaan jaringan 5G di area ini hanya dapat menjangkau cakupan area hingga seperempat dari luas area keseluruhan.

Stroke merupakan penyakit penyebab disabilitas tertinggi di dunia. Sebagian besar pasien pasca stroke mengalami penurunan fungsi motorik dan membuat pasien mengalami kesulitan dalam menjalani aktivitas sehari-hari sehingga membutuhkan bantuan pendamping. Akibat disartia yang dialami pasien menjadikan pendamping perlu berjaga sepanjang waktu di sisi pasien untuk mengantisipasi kebutuhan pasien. Hal tersebut membuat pendamping pasien memiliki keterbatasan dalam menjalani aktivitasnya sehari-hari. Berdasarkan masalah tersebut, maka dibuatlah inovasi alat bantu komunikasi pasien pasca stroke berat dengan gesture recognition berbasis Internet of Things. Alat ini dapat membantu pasien dalam mengomunikasikan kebutuhannya secara tepat sekaligus membuat pendamping pasien tetap produktif karena tidak perlu berjaga mendampingi pasien selama tidak dibutuhkan. Metode penelitian yang digunakan adalah eksperimen terencana diawali identifikasi masalah, studi pustaka, perancangan desain produk, integrasi sistem, verifikasi dan validasi produk. Berdasarkan analisis data, sistem berfungsi dengan baik, berhasil mengirimkan notifikasi perubahan gerakan (daily activity) ke aplikasi Android pendamping saat pasien ingin beraktivitas. Alat ini sangat bermanfaat untuk pasien pasca stroke sebagai alat bantu komunikasi kebutuhannya, serta bermanfaat pula bagi pendamping agar waktu penjagaan pasien tidak terbuang sia-sia. Untuk pengembangan selanjutnya alat ini dapat menyesuaikan kemampuan gerak motorik pasien yang masih berfungsi seperti gerakan kepala, raut wajah, dan lain-lain serta penambahan berbagai jenis aktivitas pada alat.

SOCRATIC DIALOGUE AS A LITERARY AND PHILOSOPHICAL PROTOFORM OF B. BRECHT’S DRAMATIC WORKS (BASED ON THE PLAY LIFE OF GALILEO)
Authors: Astrakhan N.
Published: March 2023

The article examines Bertolt Brecht’s play Life of Galileo in the context of the tradition of Socratic dialogue as a derivative of carnivalized serious and laughter forms of antiquity. The philosophical and literary genre of Socratic dialogue is characterized by a focus on searching for truth, its comprehensive polyphonic discussion, the technique of provoking with a word, and checking the thinker’s truth with his life and death; all these features are revealed in Brecht’s epic drama. The artist's innovative dramaturgy is philosophical in nature, subordinated to the objective of giving thorough consideration to the main problem of the work, building a complex system of dialogical microcontexts, the correlation of which is supposed to highlight the possibilities of its solution to the fullest extent. The poetics of epic drama moving towards the "dialectical theatre" (Bertolt Brecht’s concept) is designed to transfer the intellectual and philosophical conflict embedded in the depicted events into the viewer’s consciousness. Influenced by the aesthetics of this poetics, the viewer is supposed to change their established views on the present and, therefore, their behavior in the contemporary world, which requires a person to take active actions based on understanding the truth hidden in the depths of historical reality.
The article pays special attention to the artistic concept of man, embodied in the image of Galileo, a scientist ahead of his time who comes into conflict with the conservative majority. An artistic interpretation of the central image, in particular, Brecht’s representation of its close connection with the Renaissance, alienates the play’s material from the author’s time and personality. However, paradoxically, this alienation actualizes the lyric and biographical principle laid down by the playwright in the image of the main character; it creates prerequisites for generalization, which makes it possible to emphasize the continuity of the tradition of a selfless search for truth and constant relevance of this tradition from the era of antiquity (Socrates and Plato) through the Renaissance (Giordano Bruno and Galileo Galilei) to the author’s present (Brecht and his contemporaries: artists and scientists with their behaviours in the situation of severe political pressure).
ANALYSIS OF EXISTING ENERGY INSTALLATIONS FOR ULTRAVIOLET DISINFECTION OF RECIRCULATING NUTRIENT SOLUTION IN SYSTEMS OF CROPS AUTOMATIC HYDROPONIC IRRIGATION IN PROTECTED GROUND
Authors: Savchenko L. , Minenko S. , Savchenko V.
Published: March 2023

Decisive for solving food security problems in Ukraine while preserving and restoring the ecology of the environment should be an intensive method of management, i.e. the orientation  of  economic entities of their own activities on the innovative type of development, active use of scientific and technical developments and implementation of modern agricultural innovations. In its turn, the qualitative and quantitative indicators of crop production of protected soil depend on the technical condition of technological equipment.

The purpose of the work is research and analysis of existing power plants for ultraviolet disinfection of recirculating nutrient solution in systems of automatic hydroponic irrigation of crops in a protected soil, as well as elucidation of the impact of filtration and  disinfection  of  nutrient solution on  the presence of microorganisms when reusing plants in systems. The paper  investigates  the  ways  to improve the operation of power plants for ultraviolet disinfection of  recirculating  nutrient solution in the cultivation of crop products of protected soil. It provides the value of the required radiation dose for 90% disinfection of the  recirculation  solution  from  various  bacteria,  viruses  and  fungal  spores and the dependence of  bactericidal  efficiency on  the  wavelength  of  light. Ultraviolet rays  with  a length from 200  to 280 nm (UV-C  range) have  the  most pronounced bactericidal  effect. Research  in this area has shown that the optimal wavelength for irradiation is 253.7 nm. As a result of such irradiation, microorganisms die or lose their  ability  to  reproduce.  It has  been  proven  that  the classical layout scheme of power plants for ultraviolet disinfection of the recirculation solution is inefficient, because it does not rid the recirculation solution of turbidity and the presence of iron and does not guarantee high efficiency of the ultraviolet disinfection  plants.  The  paper  describes  the method of carbonate precipitation of metal ions, which is based on the formation of insoluble metal compounds as a result of treatment of an aqueous solution with carbonates or bicarbonates of alkali metals. Prospects for further research are the development of methods and tools to improve  the operation of power plants for ultraviolet disinfection of recirculating  nutrient  solution  in  the cultivation of crop products of protected soil.
ECOLOGICAL WATER QUALITY
Authors: Semeniuk N.
Published: March 2023

Water quality – is a description of water’s chemical and biological composition and physical properties, which characterize it as an abiotic component of aquatic ecosystem and determine its suitability for specific consumption purposes.

Ecological water quality (environmental water quality) – refers to the ecological  well-being of  an aquatic ecosystem, with the main focus on protection of the aquatic environment and human life and health. It comprises a complex of physical,  chemical,  biological  and  other  parameters  reflecting specific features of abiotic and biotic components of aquatic ecosystems.

The requirements for physical, chemical and biological properties of water are set in the water quality standards, which may be developed by particular countries or introduced by international organizations.

Ecological water quality depends upon natural and human factors. Natural factors are in their turn divided into abiotic (for example, geological, meteorological, hydrological) and biotic (for example, the ratio of primary production and organic matter destruction). The main human factors affecting water quality include  artificial  modification of  aquatic ecosystems’ hydrological conditions  and  their pollution with diverse chemical compounds.

There are a lot of approaches to  ecological  water quality  assessment according  to both  abiotic (physical and chemical) and biological parameters. Physical and chemical methods take into account such parameters as water transparency, suspended particulate matter concentration (turbidity), ion composition, water hardness, total dissolved salts content, nutrients and organic matter  content, dissolved  gases  concentration,  pH.  Biological  methods  are  based  upon  assessing  the  living organisms’ (biological indicators’) response to mineral and organic substances, present in water. Various living organisms can be used as biological indicators: algae, in particular – diatoms, higher aquatic plants, different species of aquatic invertebrates and fishes. While physical and chemical methods characterize water quality at the moment of sampling, biological  methods  provide  an integral picture of water quality for a certain time period. Besides, biological methods are more informative, because they reflect the aquatic ecosystem’s response to pollution.

On the whole, the most reliable data on ecological water quality can be obtained by combining physical, chemical and biological methods.
LAND COVER ANALYSIS OF TERRITORIAL COMMUNITIES OF ZHYTOMYR REGION USING GIS TECHNOLOGIES

Published: March 2023

Today, the deep and wide implementation of geoinformation technologies in the many fields of human activity is due to the powerful development of three scientific and technical components: statistical, software, technical and space technologies. In this article, based on GIS technologies, an analysis of the state of land use and its changes in the territory of Zhytomyr oblast was carried out, also how russian aggression against Ukraine affected these processes. The structure and the dynamics of the main classes of the land cover of the oblast for past 7 years were analyzed, the main causes and consequences of such trends were determined, and the analysis of changes in the land cover was carried out. According to the results of this study, in 2022, 52% of the territory of the Zhytomyr oblast was under forested areas, which consist of two categories: forests and other forested areas. The first category remained unchanged during the studied period since the government system of protection and reproduction of forest resources functions effectively. While the second category significantly decreased due to the fact that firewood is the most available of the fuel resources for heating building, so the population began to harvest wood in the form of felling and clearing old gardens, forested bushes and rivers (irrigation canals), forest strip. Agriculture of the Zhytomyr oblast is developing due to extensification. According to Google Dynamic World data, in 2022, 34% of the territory of the Zhytomyr oblast is systematically used for growing agricultural crops. Over the past seven years, there has been a significant increase cultivated land by 27%. In the structure of the land cover of the Zhytomyr oblast, the grass cover is 4.9%, but it is gradually decreasing. A decrease was observed for all types of territorial communities until 2021 (10% annually on average), while in 2022 the decline slowed down significantly in rural and village territorial communities and stopped in urban ones. This dynamic is connected with two factors: 1) part of the gardens of rural households were sown with grass due to the fact that men were mobilized to the Armed Forces of Ukraine as a result of russian aggression, and growing grass requires the least human costs; 2) russian aggression caused a shortage of certain food products and their significant increase in price, while keeping cattle provides food for the rural household, so in 2022 most of the offspring from cattle were not sold and left for further maintenance, in turn, the increase in cattle requires more feed, an important component of which is grass.

Published: March 2023

Introducción: el sobrepeso y la obesidad son enfermedades crónicas no transmisibles (ECNT) que en la actualidad poseen dimensiones pandémicas y se constituyen en importantes factores de riesgo cardiometabólicos para el desarrollo de otras ECNT. 
Objetivos: estimar la prevalencia de adiposidad corporal y riesgo cardiovascular mediante los índices IMC, ICC, ICA, IPM y PA y, a su vez, explorar la asociación de tales índices con información sociodemográfica, calidad de la dieta e inactividad física.
Métodos: este fue un estudio de corte transversal de prevalencia realizado en 971 adultos de ambos sexos, provenientes del área urbana de Neiva, desde junio de 2018 a junio de 2019. Los profesionales de la salud realizaron antropometría para calcular los índices anteriormente mencionados empleando protocolos estandarizados. Se utilizaron puntos de corte validados para la población latinoamericana y colombiana para la clasificación en normopeso, sobrepeso, obesidad, obesidad abdominal y riesgo cardiovascular. 
Resultados: se registraron las siguientes prevalencias: 56,5 % de exceso de peso (39,5 % de sobrepeso y 17 % de obesidad), 48 % de obesidad abdominal, 41,1 % de normopeso, 2,4 % de bajo peso, 68,5 % de riesgo cardiovascular (43 % de riesgo cardiovascular alto y 21,7 % de riesgo cardiovascular muy alto), 63,8 % de calidad regular y mala de la dieta y 57 % de inactividad física. Los índices anteriormente mencionados se asociaron con aumento de la edad, sexo masculino, aumento de la adiposidad corporal, calidad de la dieta e inactividad física. 
Conclusiones: Las altas prevalencias para exceso de peso, sobrepeso, obesidad y riesgo cardiovascular observadas en adultos de Neiva se deben en parte a la alta proporción de dieta regular y de mala calidad e inactividad física.
The Problem of Out-of-School Children in Nigeria
Authors: Oyekan Khalimath , Ayorinde Ayodotun , Adenuga Oreoluwa
Published: March 2023

In 2015, all United Nations Member States adopted the 2030 Agenda for Sustainable Development which outlines a blueprint to address global challenges across a broad range of themes including poverty, health, education, inequality, climate change, environmental degradation, peace and justice. The Goal 4 of the 2030 Agenda for Sustainable Development, otherwise referred to as the United Nations Sustainable Development Goal 4, seeks to ensure inclusive and equitable quality education and promote lifelong learning opportunities for all. Unfortunately, an approximated 263 million children remain out of school around the world. This number includes children who never started formal schooling and children who started school but later dropped out (United Nations Educational, Scientific and Cultural Organization [UNESCO], 2016). Reducing the number of out-of-school children (OOSC) is a key priority for countries across Sub-Saharan Africa, including Nigeria. This is because more than half of children globally that have not enrolled in school live in Sub-Saharan Africa, and more than 85 percent of children in Sub-Saharan Africa are not learning the minimum (UNESCO Institute of Statistics, 2018). Moreover, education is a fundamental human right, a critical driver for economic advancement and a powerful tool for poverty reduction. Hence, no child of school age should be denied access to quality and equitable education, and an opportunity to acquire skills that guarantee future employability and long-term earning. In the Nigerian context, OOSC are prevalent in both rural and urban settings, but rural areas, and isolated or deprived areas in general, consistently show higher numbers of out-of-school children (World Bank, 2019). These children are spread across the country in varying proportions. This situation is of concern to the Federal Government of Nigeria as noted in the Nigeria Education Ministerial Plan (2018-2022) which outlines several strategies targeted at bringing children back to school. In spite of these strategies, the number of OOSC remains significantly high. This insight note aims to provide an overview of the most recent data on out-of-school children in Nigeria, including breakdowns by socioeconomic and other demographic indicators. This will be followed by suggestions of possible interventions, prime of which is the Accelerated Education Programme (AEP), and other interventions which could serve to strengthen the existing laid out strategies by the government in addressing the OOSC problem in Nigeria.

Alışılmış düzenin dışına çıkılmasına ve dünyanın derinden etkilenmesine neden olan Covid-19 salgını birçok kişinin Sars-CoV-2 virüsüne yakalanmasına hatta bu virüs nedeniyle hayatını kaybetmesine sebep olmuştur. İnsan hayatını tehdit eden bir virüsün kent gibi yoğun nüfuslu bölgelerde daha hızlı yayılma hızı göstermesi birçok tedbiri de beraberinde getirmiştir. Kentlinin zorunlu yolculuklarında, sosyokültürel faaliyetlere katılmasını sağlamada önemli bir paya sahip olan toplu taşıma sistemlerine kişi sınırı getirilmesi, kamu/özel bütün kurumlarda mevcut çalışma sisteminin terk edilerek esnek, uzaktan veya dönüşümlü çalışma sistemlerine geçilmesi gibi tedbirler uygulanmıştır. Virüsün yayılım hızını kırmak amacıyla uygulanan bu tedbirler kentlinin günlük rutinini değiştirmiş ve hareketliliğini kısıtlamıştır. Bu çalışma kapsamında da kentlinin salgın dönemi boyunca toplu taşıma sistemine ve salgına karşı aşılama çalışmalarına tutumu bir vaka çalışması ile irdelenmiştir. Tekirdağ’ın merkez ilçesi konumundaki Süleymanpaşa bağlamında yapılan bu çalışmada Ocak 2021-Aralık 2021 aralığındaki toplu taşıma yolcu verileri, Covid-19 hasta sayısı verileri ve aşılama verileri kullanılmıştır. Bu çerçevede orta ölçekli bir kent özelinde En Küçük Kareler Yöntemi ile bir tahmin modeli geliştirilmiştir. Gelecekte yaşanabilecek salgınlara karşı geliştirilen modelde hasta sayıları ve aşılamanın toplu taşıma kullanımı üzerindeki etkisi ortaya konulmuştur.

About the survival of muksun embryos and larvae of the depending on the time of insemination of the eggs after collection
Authors: Lyutikov A. A.
Published: March 2023

The goal of the research was to study the viability of the offspring of the Coregonus muksun obtained from eggs inseminated at different time (-from 0 to 220 min) after collection.

Classical fish breeding methods were used in the work: eggs was inseminated by dry method, incubation was carried out in sieves and modified Weiss devices with a volume of 1 l, juveniles were grown in 60 liter pools with a stocking density of 150 ind./pool, artificial diet and artemia nauplii served as food.

Such studies in fish breeding practice are carried out for the first time, which determines their novelty.

As a result of the research, an almost linear dependence of the survival rate of the offspring of muksun on the time of insemination of ovulated eggs was established with a very high degree of approximation reliability (R2) for embryos 0,906, larvae 0,846. The best survival rate of embryos and larvae was obtained in experimental variants in which eggs were inseminated in the first hour after collection. The proportion of live eggs at the end of incubation and larvae after 38 days of rearing was 57,5-58,9% and 78-84%, respectively. The survival rate of embryos and larvae in the experimental variants in which eggs were inseminated 80-100 minutes from the moment of collection were in the range of 40,1-42,2% and 49,4-50,1%, respectively; for 120-160 minutes 9,4-15,3% and 45,3-47,6%; for 180-220 min the survival rate of caviar did not exceed 5,0%, larvae- 45,6%.

The practical significance of the work lies in determining the optimal period between the collection and insemination of eggs with the least risk to the viability of the offspring, which is of great importance in works on the artificial reproduction and cultivation of valuable fish species.
Mercury content in commercial fishes of the Barents Sea (based on long-term data)
Authors: Novikov M. A. , Gorbacheva E. A. , Kharlamova M. N.
Published: March 2023

The aim: to study the amount of mercury found in muscle tissue and liver of the main commercial fish species of the Barents Sea.

Research material was comprised of fish samples collected during the expeditions of “PINRO” named after Knipovich in the Barents Sea in 2009-2020. The study was based on muscle and liver samples taken from cod, haddock, long rough dab, Greenland halibut, plaice and spotted catfish. Over 1500 samples were analyzed. Novelty: for the first time a comparative analysis of Hg concentration in six commercial fish species of the Barents Sea was run and background readings were provided using such a big amount of data.

Methods used: the total content of Hg in fish samples was measured using Shimadzu (Japan) Cold Vapor Atomic Absorption Spectrophotometer (CVAAS). Statistical data processing and charting were done using MS Excel and application software package of Statistica 13.

Results: it was shown that the mean amount of Hg in muscle and liver of the studied fish was below the maximum concentration of 0.5 pg/g of wet weight acceptable by sanitary standards. Content of Hg in liver was two times higher than in muscle. No evidence of anthropogenic contamination of the studied species by mercury was found. The total content of Hg in muscle and especially in liver demonstrated a considerable variability, which is probably linked to seasonal changes in the diet. There might be other factors influencing the mercury concentration, such as taxonomic affiliation, regional peculiarities, physiological state, and fattiness.

Practical significance: the acquired results were used to determine whether the commercial fishes meet the sanitary standards used in Russia.
Reproductive investment in female fur seals in relation with age of puberty
Authors: Boltnev A. I. , Boltnev E. A. , Kornev S. I.
Published: March 2023

Purpose: To find out the main parameters of the life cycle and the reproductive contribution of females depending on the age of their puberty.

Method: Analysis of metal tagging in fur seal pups and tag return obtained by reading tags on live fur seals using optical instruments. Reading marks was carried out in 1982-2014 during the harem period on the Central site of the Northern rookery (Bering Island).

Novelty: For the first time, data have been obtained on the reproductive contribution of female fur seals during the life cycle in relation to their age of puberty.

Results: The birth of puppies in early maturing (at 2-3 years old) females is shifted to an earlier age, their life cycle is shorter, natural loss after the first fertilization is higher, they miss more breeding seasons during the life cycle. During the life cycle, early maturing females give birth to about 40% of the total number of puppies born by tagged females, and most of them (31%) are under the age of 8 years. Medium maturing (at 4-5 years old) females give birth to almost the same number of puppies (39.7%), however, the proportion of puppies born in these females is distributed more evenly over the life cycle. In late-maturing (at 6-7 years old) females and females entering the rookery at the age of 8+ years, the reproductive contribution is lower - they give birth to 13.4% and 6.3% of puppies, respectively, and the age at which puppies are born is higher - mostly 11 years and older.
De vreedzame school: onderwijs en de maatschappelijke vorming van de leerling
Authors: Pauw Leo
Published: March 2023

Berichten over pestgedrag op school, molestaties op het sportveld; er zijn diverse aanleidingen om ons zorgen te maken over het gedrag van kinderen en jongeren. Niet alleen in de samenleving, maar ook in de school en in de klas zorgt het gedrag van leerlingen voor problemen. Korte lontjes, weinig respect voor gezag. Het mondige en individualistische gedrag staat soms zelfs het lesgeven in de weg. De school wordt als vanzelfsprekend een rol toebedacht in de 'oplossing' van dit probleem. Onderwijs heeft immers ook een rol in de maatschappelijke vorming van jeugdigen. Sinds 2006 zijn scholen verplicht om iets te doen aan burgerschapsvorming. Onderzoek laat zien dat nu, zeven jaar later, burgerschapsonderwijs stagneert. Er is weinig sprake van een samenhangend aanbod en ook ten aanzien van de opbrengsten is het beeld niet florissant. Deze ontwikkeling roept de vraag op: wat vermag de school eigenlijk als het gaat om de persoonlijke en maatschappelijke vorming van haar leerlingen? Hoe verhoudt de invloed van de school zich tot die van de ouders, de buurt of de straat? En wat weten we over de wijze waarop burgerschapsvorming plaats zou moeten vinden? In dit boek, gebaseerd op een onlangs verschenen proefschrift, staan die vragen én de antwoorden op die vragen centraal. Dit boek levert een bijdrage aan de kennisopbouw op dit terrein. Hiertoe is het programma De Vreedzame School aan een evaluatieonderzoek onderworpen. De Vreedzame School is een schoolbreed programma voor basisscholen dat streeft naar een school als een democratische gemeenschap, waarin kinderen en leerkrachten leren om conflicten constructief op te lossen, én waarin kinderen verantwoordelijkheid leren dragen voor het sociale klimaat in de gemeenschap. Het evaluatieonderzoek naar De Vreedzame School toont aan dat een dergelijk programma niet alleen door veel scholen is ingevoerd, maar dat het tevens theoretisch goed onderbouwd is, in de ogen van de deelnemende scholen werkzaam blijkt en dat het beklijft. Het boek biedt ook zicht op welke factoren bevorderend of belemmerend werken bij de invoering van een dergelijk programma en eindigt met een negental aanbevelingen voor burgerschapsonderwijs.

Aim: Klebsiella pneumonia has emerged as an increasingly important cause of community-acquired nosocomial infections and many of these strains are highly virulent and exhibit a strong propensity to spread. Infections cause by K. pneumonia produces carbapen¬emase (KPC) enzyme and can be difficult to treat since only a few antibiotics are effective against them. Bacteriophage targeting this strain can be an alternative treatment. Characterisation of bacteriophage is utmost important in assisting the application of bacteriophage in phage therapy.
Materials and methods: In the present study, the lytic bacteriophage, k3w7, isolated by the host Klebsiella pneumoniae kP2 was characterised using transmission electron microscope (TEM), plaque assay, and restriction digestive enzyme to investigate mor¬phology, host spectrum, bacteriophage life cycle and stability accordingly.
Results and conclusions: As shown by TEM, k3w7 was observed to have the characteristic of icosahedral heads 100 nm and contractile sheaths 120 nm suggesting it belongs to the family of myoviridae.The Investigation has done on the phage growth cycle showed a short latent period of 20 min and a burst size of approximately 220 plaque forming units per infected cell. Stability test showed the phage was stable over a wide range of pH and temperatures. According to restriction analysis, k3w7 had 50 -kb double-stranded DNA genome as well as the heterogeneous nature of genetic material. These findings suggest that K3W7 has a potential use in therapy against infections caused by K. pneumonia produces carbapenemase.

For successful and productive activities, any organization has to adapt and to chase at changing of business environment. In the 21st century, managers of sports organizations, along with long-term plans, are forced to develop an adaptive business plan, because the quality of the sports industry increases and adaptive competencies help the organization develop the ability to adapt to the environment, which gives the company a competitive advantage. No matter how much we talk about to describe the sports business field in recent years, the only thing that can be said for sure is that during this period there were no certain fundamental changes, specified actions and results. In many developed countries of the world, sports business cycles and processes are accelerating, which gives an excuse to criticize more strongly the existing processes of traditional and outdated strategic planning, where a small alternative to sports industry business scenarios is proposed and there is less focus on changes in market demand. As a result, it is possible to focus on the need to develop an adaptive business plan for sports organizations and discuss the rules and methodology of its development.

The lines of this research are determined by the relevance and inadequate elaboration of the company development theory and method in view of the cyclicity of company functioning, and the urgent practical importance of activities for the reorganization of domestic business entities.
According to the author, an adequate representation of the organization is the organizational culture, the definition of the unity that is formed as independent, assimilatory development. In addition, we should understand the organization as security systems optimally protect an orderly set that has a common and ensures the protection of the internal and external environment necessary for organizational effectiveness.
Through the use of the author's adaptation mechanism, supply managers understand the life cycle in which their organization operates, evaluate the existing potential of the economic entity, determine the design structure of management systems, and create and use them. Methods of implementation of system transformations.
By using the adaptation mechanism developed by the authors, company executives will be able to understand the life cycle stage of their business activity, to estimate the available potential of the economic entity, to identify the main components of the management system to be changed, to choose and implement the proposed methods of systemic transformations. The results of the authors’ research are intended for further development of theoretical and empirical analysis in the field of organizational development.

The article analyzes that the 17.4% increase in turnover volume by the business sector, according to the results of enterprise activity, in the third quarter of 2022, in relation to the corresponding period of the previous year, is caused by a priority attitude to production efficiency: identifying the opportunities for additional capacities and their optimal use. It is clear that these processes are associated with drastic changes and require the mobilization of additional resources. But at the same time, it has a positive effect on the costs incurred per unit of production and the number of units produced. It is obvious that in the business sector, based on the results of the enterprises' activities, the increase in production efficiency is recorded in the transport and warehousing sectors. In order to ensure the quality and efficiency of work, to maintain and improve growth rates, the emphasis should be placed on all aspects of the production process. Reducing risks and losses should be a priority.
Keywords: production efficiency, productivity, transport, production, business sector, KPI.

Topicality: Blockage of hemorrhage due to vascular damage is the leading role of the clotting cascade of the hemostasis system. Recently, two types of such damage have become highly relevant. The first of them is caused by viral damage to the endothelium, which leads to uncontrolled cascade activation of the descending system. The second type is caused by aquabarotrauma and associated hydrodynamic shock. Both types of damage lead to the development of thrombotic-fibrous complications of the circulatory system due to the formation of long fibrin deposits. Such deposits are resistant to the action of the fibrinolytic system due to their irregular and chaotic structure. This, in turn, leads to severe functional complications.
Aim: Systematize data on molecular and cellular features of systemic damage to the endothelium. To compare the clinical material of persons who suffered from or died of COVID-19. To compare the functional disorders of the hearing organs in persons who have experienced akubarotrauma or who have become ill with COVID-19.
Results and discussion: The clinical material of persons who suffered from COVID-19 or died as a result of it is presented. The functional disorders of the hearing organs in persons who have experienced acubarotrauma or who have become ill with COVID-19 are considered. The reasons for the resistance of thrombotic-fibrous deposits in vessels with systemically damaged endothelium are discussed. Possible methodical approaches to overcoming the considered functional complications are discussed.
The Myth of the Altruistic University: Lessons From Universities’ Sponsoring of Events
Authors: Ambrosini Véronique , Billsberry Jon , Swanson Steve
Published: March 2023

Universities are hybrid organizations, which increasingly embark in entrepreneurial activities as a means of achieving the United Nations Sustainable Development Goals (UNSDGs). These include outreach and community engagement activities such as sponsoring cultural or sporting events.
With our conceptual expository argument, taking a multitheoretical approach, we contribute to the event management and social entrepreneurship literatures by examining how and why universities engage in UNSDGs-oriented events. This is important as little is known about how they contribute
to the UNSDGs and use events. We question the altruistic assumption underpinning their engagement. Informed by institutional theory and strategic management value-based literature, we explore why they have taken this route and suggest self-interest rather than altruism is driving their decisions
to engage in social entrepreneurship. They are value-creating strategies. We argue it is serendipity that many interpret universities’ social entrepreneurship decisions and the events that flow from them as acts of altruism.

Leukemia is the expansion of leukocyte cells in the bone marrow, which results in an increase in the number of leukocyte cells in the blood circulation and abnormal cell proliferation in the lymphatic tissue. The diagnosis of leukemia is established based on anamnesis, physical examination, and laboratory and confirmed by supporting examinations such as bone marrow aspiration to immunophenotyping. This literature review aimed to describe the role of immunophenotyping in the diagnosis of acute leukemia. The working process of immunophenotyping consists of a group of cells stained with a fluorochrome-conjugated antibody as a dye that is targeted to antigens on the cell surface. Most of these antigens are assigned a cluster of differentiation (CD) numbers. In conclusion, immunophenotyping analysis using multiparameter flow cytometry is an essential tool in detecting leukemia. Immunophenotyping examination is very useful for determining the diagnosis of leukemia. Targeted therapy is one of the modalities of leukemia therapy that is selective for certain cells that can be given based on the results of immunophenotyping.
