Published: August 2024

The analysis of the prospects of using complex genotypes at the loci of beta-casein, prolactin and leptin in marker-assisted breeding programs of Ukrainian Black-and-White and Red-and-White dairy breeds of cattle to create experimental groups of animals producing A2 milk was carried out. Data are given on the peculiarities of the distribution of allele frequencies and genotypes at the loci of beta-casein (c.350С>А, rs43703011), prolactin (c.35333764C>T, rs211032652) and leptin (c.239C>T, rs29004508) in experimental cattle populations. It was established that in both cattle populations, the loci of beta-casein, prolactin and leptin are polymorphic according to experimental mutations. The expediency of using complex genotypes for each of the polymorphic loci for the selection of individuals of both research breeds for the purpose of use in further selection work is substantiated. The number of individuals with the “desired” complex genotypes in each population was determined as CSN2A2A2PRLCCLEPCC for the Ukrainian Black-and-White dairy breed and CSN2A2A2PRLTTLEPCC for the Ukrainian Red-and-White dairy breed. According to the results of the research, it was found out that in the research group of cattle of the Ukrainian Black-and-White dairy breed, the number of individuals with the “desired” complex genotype is 10%, while in the population of the Ukrainian Red-and-White dairy breed it is 17% of the total sample (n =30). It has been proven that the minimum number of individuals required for genetic population studies (n=30, FAO) is insufficient for the effective selection of animals with the desired complex genotypes based on the identified polymorphic loci in both breeds of dairy cattle. Using the obtained data, it is proposed to carry out further marker-assisted selection in order to obtain experimental groups of A2 milk-producing animals based on the selection of individuals with the desired complex genotypes in both experimental cattle breeds using the Gene Pyramiding method. Gene Pyramiding with the markers aims to obtain individuals with the best economic traits according to the optimal breeding scheme, which involves the selection of the desired target alleles and the pyramiding of their most optimal combinations into one complex genotype.

Authors: Marenich M. M. , Karasenko V.
Published: August 2024

The relevance of the use of nitrogen inhibitors is determined by three main aspects, namely, reducing the amount of nitrogen fertilizers and, therefore, the chemical load on the environment, increasing the yield of agricultural crops, and economic feasibility. There is some information about the positive effect of the combined use of a nitrogen inhibitor and fulvic acid preparations, but there is no data on the role of humic substances such as nitrogen inhibitors. The results of the research showed a significant impact of the use of humic preparations on the formation of the yield of winter wheat. The use of UltraBoost for seed for pre-sowing treatment in the amount of 1 kg/t of seeds contributed to an increase in productivity by 0.22–0.29 t/ha, which was 4.4–6.4%. The norm of 1 kg/ha ensured a statistically significant increase in yield by 5–7.9%, which was 0.23–0.4 t/ha. In the variants of the experiment with a rate of 3 l/ha, the increase was 8.8–11% or 0.38–0.51 t/ha. The use of UltraBoost for NH3 and pre-sowing seed treatment contributed to an increase in yield by 7.1–7.5%. The rate of UltraBoost for NH3 of 1 l/ha provided an increase in yield by 0.25–0.4 t/ha, which in relative terms amounted to 3.9–7%. Twice as much rate led to an increase in productivity by 0.31–0.69 t/ha or by 10.4%. The use of nitrogen inhibitor UltraBoost for NH3 leads to an increase in the content of total nitrogen in the soil. In the variants with the application of 1 l/ha, an increase in the content was noted on average by 2.06 g/m3, which was 14.3%, and in the case of application of 2 kg/ha, the content of total nitrogen in the soil was higher on average by 3.28%, which was 22.7%. The rate of alkaline hydrolyzed nitrogen in these variants was higher by 3.5–8.8%. In variants with a rate of 1 l/ha of UltraBoost for NH3, the content of total nitrogen increased by 11.5%, and on variants with a rate of 3 l/ha – by 12.7%. The similar trend was also noted for the content of alkaline hydrolyzed nitrogen as the increase was 13.4 and 14.1%, respectively.

Published: August 2024

Studies to study the impact of various options for storing and processing manure on the content of chemical compounds in the catchment area of farms were carried out in two farms in the Kyiv region with loose housing of cows. At AIS LLC, animals are kept in an easy-to-collect room, and manure is stored in a room with a deep, long-changing straw litter separately from waste from the milking and dairy block. In Terezine ALC, cows are kept in an easily assembled room with boxes. At the same time, manure is stored and processed in a bioreactor-fermenter. Water sampling for analysis on farms, springs within a radius of 1 km from farms, and in the nearest natural reservoirs (Ros and Protoka rivers, Bila Tserkva district, Kyiv region) was carried out during the second decade of September 2021. With the option of storage and processing of manure in a bioreactor-fermenter, the concentration of chlorides was 16.36 mg/dm3 higher compared to the option of storage and processing of manure in a room with deep, long-lasting straw litter. The sulfate and phosphate content was also higher – by 11.97 and 0.01 mg/dm3 Under. The content of chlorides, phosphates, and sulfites in water samples taken within a radius of 1 km from farms was 17.22 higher than the option of storage and processing of manure in a bioreactor-fermenter; 0.02 and 11.27 mg/dm 3. The content of chlorides, phosphates, and sulfites in drinking water samples taken from drinking bowls for animals was also slightly higher for the option of storage and processing of manure in a bioreactor-fermenter by 17.22; 0.02 and 12.91 mg/dm 3. In samples of drinking water taken from drinking bowls for animals under the option of storage and processing of manure in a room with deep, long-changing straw litter, The ammonium content was slightly higher than the indicators obtained from the farm where manure processing takes place in a bioreactor-fermenter (by 0.05 mg/dm3). So, with the option of storing and processing manure in a room with a deep, long-lasting straw litter, wastewater after washing milking equipment does not get into organic waste but settles and is disposed of. With this technology, the concentration of chemical compounds in the drinking water of the farm and the springs used by the population within a radius of 1 km from the research object and in the nearest natural reservoirs with running water is lower than in the case when the water after washing the milking equipment enters the general storage of manure (bioreactor-fermenter).

Published: August 2024

The research was conducted on the farms of the Stepne State Enterprise and the Agroprogres Private Enterprise (stall housing) and on the dairy complex of the Kutuzivka State Enterprise (free housing).
It was established that the shape of the lactation curve of first-borns significantly differed from the classical one during untethered confinement. The average daily milk yield reached a maximum at 3-4 months and almost did not decrease until the 7th month of lactation. In older cows, fertility increased and reached a maximum at 2-3 months of lactation, and then gradually decreased. The relative increase in milk yield in comparison with the first month of lactation was 31% in first-born cows, 17% in second-calving cows, 7% in third-calving cows, and 18% in older animals, and in stall housing – 33%, 17%, 10 % and 2 %, respectively. The power of influence (η2) of the month of lactation on the fat content in milk during untethered confinement was 8.5% in first-born cows, 14.5% in the second lactation, 13.1% in the third lactation, 12.2% in older cows, and for tethered confinement 14.8%, 36.9%, 33.6%, and 11.6%, respectively (р<0.001). Similar to the fat content in milk, the protein content of cows also changed during lactation. At the same time, the influence of the month of lactation on this indicator was much smaller than on the fat content, and in some cases it was improbable for stall housing.
The influence strength of the month of lactation on the daily yield of cows that were culled from the herd was 23.8% for free housing, 1.9% for body weight, and 8.0% for stall housing and 11.6 % (p<0.001). Correlation coefficients are 0.181, +0.411, and –0.223, +0.335, respectively (p<0.01).
Age-related changes in the body weight of animals depended on the technology of their husbandry. In free housing, it was higher both in the sample as a whole (6%) and in animals of different lactations (3-14%). The increase in body weight of cows with age in free housing was: 31 kg in the second lactation, 71 kg in the third lactation, and 100 kg in adult cows, while in stall housing these differences were only 6, 11, 35 kg, respectively.

Keywords: husbandry technology, dairy cattle, age, month of lactation, daily yield, fat content, protein content, body weight
EFFICIENCY OF THE USE OF TYPICAL AND INNOVATIVE RATIONS FOR FEEDING COWS IN THE SOUTH OF UKRAINE
Authors: Alsaliheen Elfeel Ayman Anwar , Susol Ruslan , Kirovych Nataliia
Published: August 2024

The paper presents an innovative view of the recommended feeding rations for effective milk production on an industrial basis in the conditions of southern Ukraine, taking into account the fact that this territory belongs to the zone of risky land use and the negative effect of global warming, which has been manifested in recent years. Scientific and economic experiments were carried out at the State Enterprise “SF Andriyivske” of the Bilhorod-Dnistrovsky district of the Odesa oblast according to generally accepted methods. The advantages of using winter rye as a crop whose growing season falls on wetter periods of the year have been established, which makes it possible to harvest high-quality silage with an energy content of 12.0 MJ, crude protein 12.7%, neutral detergent fiber 51.9% in the calculation per 1 kg of dry matter. A tendency to advantage in terms of milk yield was established from the cows of the experimental groups that received rye silage in combination with wet beer groats as the main fodder. Taking into account the ratio of fat and protein in the milk of the cows of the experimental groups in our studies, the optimal ratio of fat: protein was established in the cows of IV experimental group (1.2: 1), whose rations as the main forage contained only 45.0 kg of rye silage with the addition to this 6.0 kg of wet beer grain. The use of rye silage in combination with wet beer groats in the feeding rations of the cows of the experimental groups revealed a positive effect on indicators of rumen fullness, manure consistency, feed digestion, cow fattening, health status, reproductive capacity and animal survival. A tendency was established for the superiority of the milk yield of the cows of the experimental groups for 305 days of lactation by 95-258 l, respectively, compared to the animals of the control group, where the milk yield was 7,898 l, which, due to the use of cheaper ingredients in the rations, made it possible to reduce the cost of production of 1 liter of milk by 11.3-23.7%.
A top predator does not provoke stronger defense than a mesopredator in an intraguild prey
Authors: Gladow Kai-Philipp , Jablonski Marla , Chakarov Nayden , Krüger Oliver
Published: August 2024

The loss of top predators has been shown to lead to drastic changes in community structure. An important part of this is the shift in behavior of other species. The understanding of such changes is scarce because recordings of behavioral reactions towards lost species are rarely done. This is important for predators experiencing predation pressure themselves, known as intraguild predation. Re-colonizations offer the unique possibility to fill this knowledge gap. However, only a few studies tested experimentally how subordinate predators change their behavior towards top predators in comparison to other members of their guild. Birds adjust the level of nest defense in response to perceived threats. Therefore, we expected birds of prey in intraguild predation systems to show an appropriate level of nest defense against the predator they are faced with, with the highest level shown against the top predator. We tested this by placing models of eagle owls (Bubo bubo) and goshawks (Accipiter gentilis) close to nests of common buzzards (Buteo buteo) and measured the reaction. Additionally, we compared the development of the three populations and tested for other influences on the defense behavior. We did not find significant differences in aggression by common buzzards toward eagle owl and goshawk and therefore conclude that the top predator does not provoke a higher nest defense than another (meso-)predator. This shows that in ecological communities the top predators and mesopredators may not have separated levels from the viewpoint of intraguild prey. Top predators and mesopredators might be perceived as comparable threats.
Reversing the North American bumblebee decline: Looking at farming practices could be a solution
Authors: Videle Jimmy
Published: August 2024

Wild bee declines have been documented worldwide, particularly in bumblebees, with some species in Nort America declining over 90% in the last 20 years. Climate change, land-use change from agriculture, pesticide use, and apiculture are the main drivers. The 2.2-hectare farm La ferme de l’Aube is the research site of a larger 3,082-hectare biodiversity reserve. The study area saw a 340% increase in the bumblebee population from 2018-2024, demonstrating that veganic practices of cultivation including low-till, non-toxic spraying, cultivation of flowering plants that bloom throughout the season, permanent ground cover and re-wilding the adjacent forest and edge could have contributed to the increase.

Authors: Iranzo Esperanza , Nicolau José Manuel , Reiné Ramón , Tormo Jaume
Published: August 2024

The transition from fossil fuels to renewable energy sources is fundamental to mitigate the effects of global climate change. Renewable power capacity is increasing globally, and solar photovoltaic will be the dominant renewable energy source by 2050. Photovoltaic parks require great extensions of land, usually in drylands. But both ecosystems created by solar parks and the effect of solar parks on ecosystems are scarcely studied. This paper reviews the current knowledge on the impact of solar energy production on arid and semiarid ecosystems and describes the structure and functioning of these novel ecosystems, including changes in microclimatic conditions, soil quality, vegetation, and biodiversity and show how these factors hinder the full recovery of ecosystems in the solar parks. Finally, we address the limitations and challenges of restoring ecosystems within photovoltaic power plants and suggest the use of modern ecological restoration techniques and the incorporation of grazing with rational planning to improve the ecosystems in photovoltaic power plants in drylands. In any case, more research is needed to fully understand the long-term impacts of photovoltaic parks on the environment and the evolution of the novel ecosystems in the photovoltaic power plants.
Dormancy in the origin, evolution, and persistence of life on Earth
Authors: Webster Kevin , Lennon Jay
Published: August 2024

Life has existed on Earth for most of the planet's history, yet major gaps and unresolved questions remain about how it first arose and persisted. Early Earth posed numerous challenges, including harsh, noisy, and fluctuating environments. Today, many organisms cope with such conditions by entering a reversible state of reduced metabolic activity, a phenomenon known as dormancy. This process protects inactive individuals and minimizes the risk of extinction by preserving information that stabilizes life-system dynamics. Here, we develop a framework for understanding dormancy on early Earth, beginning with a primer on dormancy theory and its core criteria. We hypothesize that dormancy-like mechanisms acting on chemical precursors in a prebiotic world may have facilitated the origin of life. Drawing on evidence from phylogenetic reconstructions and the fossil record, we show that dormancy is prevalent across the tree of life and throughout deep time. These observations lead us to consider how dormancy might have shaped nascent living systems by buffering stochastic processes in small populations, protecting against large-scale planetary disturbances, aiding dispersal in patchy landscapes, and facilitating adaptive radiations. Given that dormancy is a fundamental and easily evolved property on Earth, it is also likely a feature of life elsewhere in the universe.

Authors:   Simon Kuznets Kharkiv National University of Economics, Kostin Illia D.
Published: August 2024

Digital innovation projects occupy a leading place in the modern mechanism for stimulating economic development. The key in this context is the formulation of a system for evaluating the efficiency of these innovations. The aim of the article is to compare the key methods for evaluating the efficiency of digital innovation projects and to develop instruments to improve the efficiency of the results of these projects. This article proposes a model for assessing the socioeconomic efficiency of digital innovation projects using five key methods, namely: net present value; internal rate of return; profitability index; risk-based efficiency assessment method; social return on investment. Each of these assessment methods is described in the context of its strengths and weaknesses, as well as typical application situations. The article also examines the specifics of innovative projects, including their uncertainty, high risk, and the potential for a significant impact on society and the economy. The importance of introducing a system of key efficiency indicators, which allows you to quantify the success of innovative projects, for example, by measuring the time to implementation, the level of customer satisfaction and the efficiency of the use of resources, is emphasized. Recommendations for the State policy in the field of stimulating the development of innovations have been formed, which emphasizes the importance of financing scientific research and implementing insurance programs and supporting innovative projects. It is emphasized that such an approach can ensure sustainable economic development and a response to the social needs of modern society. The proposed article can be useful for researchers and analysts in the domain of digital innovation projects, business, the State and local authorities. Prospects for further research include the development of a digital dimension of the proposed key efficiency indicators using data from other benchmark countries for digital innovation activity.

Published: August 2024

Digitalization has changed retail forever and will keep making changes. Customers can now shop from the comfort of their own homes, with access to a variety of products, and easily comparing prices. At the same time, digitalization also poses challenges, especially for traditional small-scale retailers who cannot keep up with the pace of digitalization of the industry and society as a whole. The object of the research is the processes of introduction of digital innovations and the activities of small enterprises in the field of trade. The subject of the research is digital innovations in the sphere of trade and their impact on the activities of enterprises and consumer experience. The article discloses the concept of «digital innovation», identifies and characterizes the factors that influence the processes of introduction of digital innovations in the sphere of trade. The considered and analyzed models of consumer behavior in the context of digitalization of trade demonstrate that the latter are used as quite traditional approaches to the process of purchasing, complete immersion in the online space, as well as mixed forms. Attention is paid to the recently popular ROPO effect (Research online, purchase offline). The use of a number of digital technologies will help improve trade processes and consumer experience. It is proposed to use a systematic approach to the implementation of digitalization measures in the activities of small trade enterprises on the basis of the digitalization pyramid, which consists of four main areas of activity: optimization of internal processes, visibility on the Internet, digital sales and artificial intelligence. According to the pyramid, the path of digitalization is a series of separate stages, when, without passing the previous level, it is not recommended to master and implement what the next level entails. The identified advantages and disadvantages of the introduction of digital innovations in trade make it possible to find out the main problems and directions of development of trade enterprises in the digital age.

Authors:   Academy of Recreation Technologies and Law, Vitovshcyk Tetiana S. , Bazavluk Nataliia G. ,   Poltava University of Economics and Trade
Published: August 2024

The article is devoted to the consideration of the main provisions and substantiation of the essence of eco-innovations as the main competitive advantage in a closed-loop economy. In the course of the study, the authors consider the features of the development of eco-innovations, taking into account the features of a closed-loop/circular economy. The paper describes the genesis of the concepts of «innovation» and «eco-innovation» in scientific literature and regulations – both international and national. The study is supplemented by an analysis of the domestic legislative field. When synthesizing the existing definitions of the essence of the category of «eco-innovation», two essential approaches (as process and as product) have been identified for the first time. The erroneous interpretation of the essence of «eco-innovation» as process under the condition of the simultaneous existence of the category of «innovation process» has been proved. A theoretical distinction is made and the cause-and-effect relationships between the concepts of «innovation process» and «eco-innovation» are studied, the results of which are presented graphically. The authors propose their own definition of the concept of «eco-innovations» (which does not contradict the norms of the current legislation) within the framework of the essential approach «as product» of newly created (applied) and (or) improved competitive technologies, products or services, as well as organizational and technical solutions of production, administrative, commercial or other nature, created by the company itself or other external structures in order to reduce or prevent eco-destructive impact on environment throughout its life cycle, while ensuring the profitability of economic activity. The classification of «eco-innovations» is considered; technological, organizational, social, and institutional innovations are allocated, and the essence and features of each of the subordinate types are described. Two modern ecosystems – open and closed-loop – are characterized, their distinctive features are presented. The expediency and necessity of production and implementation of eco-innovations for economic entities and the State are substantiated.
The State Support for Entrepreneurs During the Wartime
Authors:   O. M. Beketov National University of Urban Economy in Kharkiv, Mozgovyi Ievgen V.
Published: August 2024

The article is devoted to the substantiation of measures for the State support of entrepreneurs during the wartime. The publication proves the relevance of the study of the problems that arise in the process of substantiation and implementation of measures for the State support of entrepreneurs during the wartime. According to the results of the carried out analysis of modern scientific works on the topic of research, it is found that domestic scholars analyze the legislation that regulates entrepreneurial activity, and highlight trends in the development of entrepreneurship, taking into account the experience of developed countries in this area. At the same time, the problems of entrepreneurial entities are not given due attention. Measures for the State support of entrepreneurs are proposed, which provide for full or partial reimbursement by the State of the costs of restoring objects that were damaged during hostilities (it is recommended to divide the objects in need of restoration into groups and determine the priority of restoration for each of them using the adapted method of the sum of years, which is traditionally used to calculate the depreciation of fixed assets). The necessity of reducing the level of tax pressure on entrepreneurs is also substantiated. The main argument in favor of such a step on the part of the State is that the reduction of the level of taxation of entrepreneurs will gradually lead to a decrease in the shadow sector of the economy and an increase in the number of taxpayers. This point of view is substantiated using the conception of elasticity: it is illustrated that a relatively small reduction in tax pressure will lead to a significant increase in tax revenues. In addition, the article proposes to take into account the amount of financing by entrepreneurs of the needs of the Armed Forces of Ukraine and reduce the tax base or the amount of tax payments depending on the amount of such financing. Perspective areas of research on the problems that arise in the process of organizing the State support for entrepreneurs include: formulation of proposals for improving tax legislation to reduce the level of tax pressure on entrepreneurial entities; identification of factors influencing doing business during the wartime and assessment of such impact using mathematical tools; development of a mechanism for motivating entrepreneurs to more intensive volunteering.

Authors:   Simon Kuznets Kharkiv National University of Economics, Budarin Oleksii S.
Published: August 2024

The article presents the results of a study of the problem of import substitution at two levels of management, namely: macro- and micro-level. The aim of the article is to substantiate the scientific, methodical and practical aspects of import substitution in the current conditions of enterprise activity. On the basis of the analysis of the works of well-known experts on the problems of export-import activity, it is proposed to consider import substitution as a process of ensuring the efficiency of activity by: production of own competitive products with high added value; replacement of imported raw materials, materials and components with domestic ones that have a lower cost; diversification of production of quality products of lower value, which replaces imported products in the domestic market. Such a definition specifies the ways of import substitution in the conditions of a real enterprise. The problems and prospects of implementation of the import substitution strategy in the machine-building industry are considered. An analysis of the implementation of the import substitution strategy at the enterprise of JSC «Ukrainian Energy Machines» has been carried out. Some aspects of methodological support for determining import substitution at enterprise have been proposed. A multifactorial regression model of dependence of profitability of enterprise activity on the volume of exported products and volumes of imported raw materials, materials and components has been developed. On the basis of the SWOT analysis, effective ways to implement the import substitution strategy at the enterprise to improve the efficiency of its activities have been identified.

Authors: Adikwu Gowon Jacob , N. Tambawa , Oluwasesan M. Bello
Published: August 2024

The study aimed to extract oil from Arachis seeds (Arachis hypogaea), characterize the oil with FTIR and GC-MS, and use it to produce laundry soap. Arachis oil was extracted via the Soxhlet method in nhexane. Standard methods were adopted to examine the properties of the extracted oil, and the produced laundry soap. Fourier-Transform Infrared Spectroscopy (FTIR) and Gas Chromatography-Mass Spectrometry (GC-MS) were used to analyze the chemical composition of the oil. The results showed that 70.0 g of the Arachis seed gave 49.56±1.24 % oil yield. The physicochemical characterization of the oil showed that the relative density, saponification value, acid value, and iodine value were 0.65±0.15 g/mL, 190.74±2.17 mgKOH/g, 2.08±0.15 mgKOH/g, and 91.88±0.25 gI2/100g, respectively. Functional groups analysis from FTIR data revealed unique absorption peaks of methyl group at 1379 cm–1, methylene group at 723, 1461, 2847, 2922 cm–1, carbonyl group at 1744 cm–1, and olefin group at 1654 cm–1, which are attributed to the fatty acids present in the Arachis oil. The GC-MS analysis confirmed the following fatty acids: Oleic acid, Elaidic acid, and Vaccenic acid in the oil. The soap’s quality parameters determination offered 99.75±0.26 cm, 4.63±0.37 cm, 7.10±0.78 % and 59.25±2.65 % for pH, foam height, moisture content and total fatty matter, respectively. Besides, the soap was slightly pinkish and moderately hard. The findings of the study proved that Arachis seeds oil is a richsource of fatty acids with the required functional groups for efficient saponification reaction, and has a huge potential for large-scale production of quality laundry soap.

Published: August 2024

Fairphonic Pte Ltd is a technology company operating in the music sector. Fairphonic provides services to detect content on social media that is suspected of copyright infringement. Fairphonic utilizes audio features for the detection process. The current algorithm used by Fairphonic requires pairwise comparison, and the content to be compared is collected through a scraping process immediately after the process is run. Fairphonic has hundreds of thousands of music data in their database. Fairphonic desires a more scalable algorithm to compare an input music piece with the entire Fairphonic music catalog. This research uses features such as Harmonic Pitch Class Profile (HPCP), Chroma, and Rhythm Pattern. The study compares previously researched algorithms, namely binary similarity matrix, Euclidean distance, and similarity matrix profile. The results show that the combination of HPCP with the binary similarity matrix yields the highest Mean Average Precision of 0.989. Speed testing by performing comparisons 10 times shows that the combination of Chroma and the similarity matrix profile is 72% faster compared to the combination of HPCP with the binary similarity matrix. The author recommends the Chroma and similarity matrix profile algorithm for music similarity ranking due to its faster process.

A programok a sportág alapjainak tanmenetbe történő beépítését célozzák. A kutatás célja, hogy a kapott eredmények hatására egy reális képet kapjunk a sportág jelenlegi helyzetéről, hiszen az iskoláknak adott az a lehetőség, hogy éljenek az alternatív kerettanterv lehetőségeivel, melyben megtalálható a Kajak-Kenu – vízi jártassági ismeretek tantárgy. Ezen foglalkozások célja, hogy a gyermekek minél szélesebb körben megismerkedjenek a vízi jártasságok alapjaival és a vízi sportokkal, minél több természetközeli élményt szerezzenek, és megismerjenek egy komplex, szabadtéren, speciális környezetben végezhető, számos képességfejlesztést kielégítő sporttal. Ennek érdekében szükségszerű, hogy a tanuló megismerkedjen a különböző sportágak mozgásanyagával, ezen tevékenységeknek a tanulók sokoldalú testi, lelki és szellemi fejlesztésében betöltött szerepével. A kajak-kenu sportág biztosíthatja a gyermek számára, hogy egy élményekben gazdag képzésben vegyen részt. Mivel a kutatásban több kérdés is felmerült, az adatfelvétel során három kérdőívet használtunk, kettő a vizsgált iskolák tanulóinak, egy pedig a Jász-Nagykun-Szolnok megyében tanító testnevelőknek a részére készült, illetve három interjút készítettünk az iskolai kajak-kenu oktatásban részt vevő szakemberekkel. Az iskolai program során a fejlesztő hatások természeti közegben, önfeledt hangulat mellett érvényesülhetnek és épülhetnek be a gyermek testkultúrájába és személyiségébe. A kajak-kenu sportág beépítése a mindennapos testnevelésbe mind a gyermekek, mind a pedagógusok részéről nagyon pozitív hozzáállást eredményez.

A kognitív képességek az élet minden területén fontos szerepet játszanak abban, hogy sikeresen végezzük tevékenységeinket. Mint minden képesség, ez is fejleszthető, méghozzá az egyik legelemibb módszerrel, a mozgással. A mozgás és a kognitív folyamatok bizonyítottan hatással vannak egymásra, ebből kifolyólag az iskolai testnevelés is számos agyi terület, a kogníció fejlődését biztosíthatja. A kutatás célja, hogy bebizonyítsuk, hogy az innovatív eszközök segítségével végzett fejlesztések a fejlesztésben részt vevő csoport esetén rövid időn belül pozitív irányú változást fognak eredményezni más tantárgyak vonatkozásában is. A kiválasztott 22 fő elő- és utóméréseken vett részt, amelyek a gondolkodási képességekre, az észlelésre, a téri tájékozódásra, a reakcióidőre, a figyelemre, a figyelemmegosztásra, az emlékezetre, a munkamemóriára, valamint további területekre, mint a beszédértés, beszédészlelés, asszociációs képesség, számolási képesség irányultak. Az előmérések folyamán a kontrollcsoport jobb eredményt produkált. A felmérések tükrében a kísérleti csoport 11 fővel 2 héten keresztül, heti 3 alkalommal célzott kognitív képességfejlesztést végzett a testnevelésórák folyamán. A fejlesztések játékos formában, innovatív eszközökkel valósultak meg. Az utómérések eredménye és a páros t-próba alapján egyértelműen megállapítható a kísérleti csoport szignifikáns fejlődése, mind a tantermi, mind a mozgásos mérésekben, míg a kontrollcsoport eredményei minden esetben stagnálást vagy romlást mutattak. További kutatásra javasolt terület más, nagyobb korosztályokat magába foglaló intervenció.

Nuevas terapias para el manejo de los síntomas vasomotores en la menopausia
Authors: Llumitasig Trujillo Jeniffer Pamela , Padilla Vinueza Verónica Elizabeth
Published: August 2024

Introducción. La menopausia trae cambios físicos y psicológicos que pueden afectar las relaciones personales y familiares. Muchas mujeres no buscan ayuda médica debido a la falta de información, dificultades de acceso y preocupaciones sobre los efectos secundarios de las terapias hormonales. Los nuevos tratamientos no hormonales, como los antagonistas de la neuroquinina B, muestran promesas en aliviar eficazmente los síntomas vasomotores. Objetivo.  Analizar el impacto de la menopausia en la vida de las mujeres, identificando las barreras que enfrentan para buscar ayuda médica y evaluar la efectividad de los tratamientos no hormonales recientes, como los antagonistas de la neuroquinina B, en la mejora de los síntomas vasomotores y la calidad de vida. Metodología. Esta revisión bibliográfica sirve como base para un estudio retrospectivo que evalúa críticamente la literatura seleccionada bajo diversos criterios. Resultados. Diversos estudios han investigado la eficacia de los antagonistas de la neuroquinina B, como el fezolinetant, en el tratamiento de los sofocos menopáusicos. La investigación ha demostrado que la vía de la neuroquinina B regula la secreción de GnRH y, por tanto, juega un papel crucial en el control de los sofocos. Conclusión. Durante décadas, la terapia hormonal ha sido eficaz para aliviar los síntomas de la menopausia, como los sofocos, aunque conlleva riesgos como el tromboembolismo venoso y el cáncer de endometrio. Esto ha llevado a la búsqueda de alternativas más seguras y efectivas, como los antagonistas de NK3R y la neuroquinina B, que se están evaluando en términos de eficacia, seguridad y tolerabilidad en comparación con la terapia hormonal tradicional.

Introducción: La obesidad es una enfermedad crónica, compleja y recurrente, considerada como un factor de riesgo de múltiples enfermedades, entre ellas, las que están relacionadas al sistema cardiovascular; actualmente estos riesgos se han vistos disminuidos por el uso de la liraglutida en el tratamiento para pacientes obesos, demostrando una notable disminución del apetito y aumento de la saciedad, por ende, mejora las funciones metabólicas, promueve la secreción de insulina y disminuye el vaciamiento gástrico; este medicamento es muy bien tolerado y altamente eficaz, lo que justifica su alto costo. Objetivo: Describir los beneficios terapéuticos en la obesidad y el riesgo cardiovascular generando conocimientos de la situación terapéutica actual de la liraglutida. Metodología: Se realizó un estudio descriptivo documental utilizando descriptores para buscar literatura relevante en bases de datos como Scopus, Elsevier y PubMed, tanto en español como en inglés. La búsqueda se efectuó a través de Google Académico con operadores booleanos para afinar los resultados. Se recolectaron, revisaron y analizaron las fuentes bibliográficas, gestionadas con Mendeley, seleccionando 29 artículos recientes y relevantes sobre los beneficios terapéuticos de la liraglutida en la obesidad y el riesgo cardiovascular. Resultados: La Liraglutida es un análogo del GLP-1 humano con 97% de homología, adecuado para dosis diarias en pacientes con diabetes tipo 2. Absorbida lentamente, su vida media es de aproximadamente 10-14 horas. Tiene como función reducir la glucosa, apetito y riesgos cardiovasculares. Su metabolismo es similar al GLP-1 nativo, y se elimina a través del hígado y riñones. Conclusión: La liraglutida como agonista del GLP-1 demostró ser efectivo en la reducción del peso corporal y el apetito, esto se evidenció gracias a estudios y metaanálisis, donde se demostró que mejora las funciones metabólicas en el paciente; uno de sus efectos es la mejoría general del perfil glucémico, causando una disminución de incidencia de enfermedades cardiovasculares como HA, DT2 e IAM.
