Published: July 2024

In the scientific community, the generally accepted vision of indicators of physical development of children and adolescents as indicators of the health of the whole population has gained a dimension. The current relevance of the problem of non-fixed disorders of the musculoskeletal system of athletes is revealed by the results of scientific research devoted to the determination of the peculiarities of disorders of the biomechanics of posture and foot of young athletes representing various sports. The purpose of the article is to determine the peculiarities of posture of young athletes specializing in hand-to-hand combat. Methods: theoretical analysis and generalization of special scientific and methodological literature, photography and posture analysis, visual screening of the biogeometric posture profile of young athletes were used in the study. Results. It has been shown that postural disorders of various types are a common phenomenon among athletes aged 8-14 years who specialize in hand-to-hand combat covering a contingent of 46.7% to 60% in different age groups. In addition, a significant proportion of young martial artists with normal posture (62.9% of them) can be classified as at risk of postural disorders, primarily due to a marked deviation from the norm in the position of the pelvic bones, waist triangles, symmetry of the lower angles of the scapulae in the frontal plane, as well as deviations in the lumbar lordosis in the sagittal plane. Differences (at the level of trends) between athletes of different ages have been identified, which indicate a certain deterioration in the state of the biogeometric profile of posture with increasing age, but such differences have not been statistically confirmed. On the basis of systematisation and generalisation of professional sources it seems possible to state that today the theory of sport has in its arsenal a significant layer of scientific data that make it possible to carry out sports training of young sportsmen, taking into account morpho- biomechanical properties of organism development during its growth. The theoretical and practical aspects of the above scientific work will be the basis for theoretical substantiation and experimental verification of the effectiveness of the author's technology for the correction of postural disorders of young athletes specializing in hand-to-hand combat.

Relevance of the research topic. Studying the state of support-spring properties of the foot of primary school-aged children is an important indicator of their physical development. Particularly relevant is the study of the state of support-spring properties of the foot for children who are systematically engaged in physical exercises. Exploring the possible influence of physical exercises and other factors on the state of support-spring properties of the foot expands the scope of approaches for preventing their disorders. The purpose of the research is to assess the state of the support-spring properties of the foot of primary school-aged children who are engaged in hand-to-hand combat. Material and methods. 81 children of primary school age who systematically attend hand-to-hand combat classes participated in the study. The children's and parents' consent to participate in the study was obtained. Research methods included: analysis and generalization of scientific and methodological literature, Internet sources, anthropometric research methods, pedagogical research methods, mathematical statistics methods. To study the support-spring properties of children, the length, width of the foot, the height of the longitudinal arch of the foot, the Dahle angle were measured, the Weisflog Index, the Chizhyn Index were calculated, and the Ocheret method was carried out. Results. The overall number of deviations in the support-spring properties of the foot among primary school-aged children tends to decrease with age. The highest number of deviations was observed among 7-year- old children (77.78 % in girls and 75 % in boys). Regarding the nature of deviations in individual indicators of the support-spring properties of the foot, the highest number was found in the spring properties of the foot, specifically in the height of the longitudinal arch of the foot in a relaxed state and under load, according to the Ocheret method.The influence of body mass on the indicators of the support-spring properties of the foot was investigated. Conclusions. The cohort of primary school-aged children is characterized by a significant number of deviations in the basic structural elements as well as in their performance of the spring function. Studying the state of the support-spring properties of the foot allows for the elucidation of strategies for preventing their disorders.

The article substantiates the development of a concept for the development of sheep breeding in the Trans-Baikal Territory, the implementation of which will make it possible to comprehensively ensure the development of the industry, taking into account the local breed composition of animals, the availability of agricultural land, and the functioning of breeding organisations. The concept formulates the goal, objectives, object, and research subject. The main directions of the developed concept are: obtaining organic sheep products - meat, milk, wool, sheepskin; ensuring a unified processing cycle for sheep products, incl. wool, from raw materials to yarn; maintaining environmental balance (preventing desertification); efficient use of agricultural land; expansion of exports of sheep products. The main directions of the developed concept are: obtaining organic sheep products - meat, milk, wool, sheepskin; ensuring a unified processing cycle for sheep products, incl. wool, from raw materials to yarn; maintaining environmental balance (preventing desertification); efficient use of agricultural land; expansion of exports of sheep products. The principles and the possible effectiveness of the proposed directions for the development of sheep breeding are determined. The recommended activities will facilitate selection and breeding work between agricultural producers and breeding organisations, the creation of a consumer cooperative to ensure integrated processing of sheep products, the development of new technologies for improving natural pastures, the use of pasture rotation and the development of organic sheep farming, and export activities of processed sheep products.
The factor of peasant (farmer) farms' activity in solving food security issues in the Republic of Khakassia.
Authors: Shaposhnikov G. M. , Chagin V. V. , Gavrilets N. V.
Published: July 2024

The article shows the formation and development of peasant farms in Khakassia. During a long historical period (about 100 years) there were successive changes in the forms of organization of peasant labor from the so-called kulak farms through the creation of collective farms (kolkhozes) of the Soviet time to the acquisition of the status of peasant farms by the end of the 1980s. At the initial stage, the number of such farms grew steadily and reached 270 thousand, but during the reforms of the 1990s their sharp quantitative decline was registered. The consequence of these processes was naturally a general decline in the production of livestock products, which in the early 2000s amounted to only 53 % of the amount of product produced by the early 1990s. Traditionally, the product of special importance for Khakassia was mutton, the production of which fell by a catastrophic 82 %. There were many reasons for such negative processes in the functioning of peasant farms at the end of the 20th century, including the lack of demand for sheep wool. Nevertheless, at present the main suppliers of high-quality and ecologically clean livestock products in Khakassia continue to be personal subsidiary farms of various types, of which peasant (farmer) farms are in second place in terms of production volumes. If we talk about the output of livestock production per capita per year in the republic, then in recent years there has been a marked decline in the production of beef (from 41 to 38.1 kg), milk and dairy products (from 273 to 246.4 kg). Among its neighbors in the Siberian Federal District in the production of meat and meat products the Republic of Khakassia is on the penultimate place, ahead of only Tyva, and in the ranking of dairy production - only one position higher, occupying a place before Tyva and Krasnoyarsk Krai. The paper provides a comparative analysis of factors that allow increasing the output of agricultural products by farms of different forms of ownership for different soil and climatic conditions of the Republic of Khakassia.

Authors: Erlikh V. A.
Published: July 2024

Based on the analysis of Russian-language literature of the last decade, the paper presents a picture of the current state of published works on the development of hunting in traditional societies of Siberia and the Far East from ancient times to the arrival of Russians. A list of publishing cities and publishing centers, the volume of publications, their typology and circulations are given; specific epochs and territories that were considered in the works are named. The topic of publications is given, examples of the structure of works and some points of view of the authors on the development of hunting in the region in antiquity and the Middle Ages are given. It is concluded that in the second and early third decades of the XXI century, the publication of works that dealt with the history of hunting in the aboriginal societies of Siberia and the Far East was quite active. A list of publishing cities is presented. It was found that mostly articles published in various continuing and periodicals were published. The monographs, which contained information about hunting, were works of a generalizing nature. The works, where there was information about the development of hunting, covered various areas: Trans-Urals, Baraboo, Upper and Lower Ob, Altai, Baikal, Transbaikalia, Amur region, Northeast Asia, etc. The development of hunting in different eras before the arrival of the Russians is highlighted, but especially great attention was paid to the Paleolithic era. The subjects of the works were different: the composition of animals, an overview of fauna, issues of paleoecology, the influence of climate, a set of hunting equipment, the use of dogs and sleds, hunting techniques, specialization of hunting activities. The authors’ points of view given in the work allow us to speak about the breadth of their interests in studying this problem, and that the main attention was paid to the set of animals that were hunted at one time or another.
Formation of the harvest of cereal and legumine agrocenoses on the territory of the Shebalinsky district
Authors: Salnikova Ye. A.
Published: July 2024

The Altai Republic has a livestock sector, so the main task of crop production is to increase the production of high-quality and balanced feed. This article presents the results of research on the productivity and nutritional value of cereal and legume agrocenoses cultivated in the mid-mountain zone of the Altai Republic. Field experiments were conducted on the basis of the “Experimental station “AESKH”, the village of Cherga in the Shebalinsky subzone of the mid-mountain zone of the Altai Republic. Annual cereal and legume forage crops were studied in single-species and mixed crops. The results of research on the growth, development, yield and nutritional value of cereal and legume agrocenoses over two years are presented. The following types and varieties were used in the test: from cereals – oats Argument, Sudanka Prialeiskaya 7; from legumes – Altai universal peas and Siberian clover 2. The ratio of grass mixtures during sowing: 70 % of cereals and 30 % of legumes. The most productive options were oats + peas and oats + sweet clover. These agrocenoses formed an average of 12.5 to 22.0 t/ha of green mass in two years. According to the availability of digestible protein for 1 feed unit, the best result was shown by the options: oats + donnik (124 g), sudanka + donnik (130 g). The following options have a great advantage in terms of energy exchange and feed units: sudanka + peas, oats + sweet clover. All the agrocenoses studied by us correspond to the zootechnical norm of providing 1 feed unit with digestible protein 105-115 g. Legumes in single–species sowing are sufficiently highly provided with digestible protein and, when added to the cereal component, provide a higher-quality feed balanced in protein.
Productive and quality indicators of broiler chickens when introduced to the diets milk whey
Authors: Gorodok O. A. , Lenivkina I. A.
Published: July 2024

Research results have shown that the use of whey SGOL-1-40 in the diets of broiler chickens leads to improved growth and development of poultry. In particular, an increase in body weight of 5–7 %, improved digestion and absorption of nutrients, as well as increased immunity and a decrease in poultry morbidity were noted. Feeding of this additive also affected the productive indicators of poultry: an increase in live weight, which was higher during all periods of growing (significantly at P ≤ 0.99) in relation to the control group, indicators of absolute and average daily gain; safety of livestock (increased by 2 %), reducing feed costs (in the 2nd group compared to the 1st by 4.2 %). The use of whey SGOL-1-40 in diets for raising broiler chickens has reduced the cost of feeding poultry, since the additive contains many nutrients that make it possible to reduce the amount of other feed additives. Feeding SGOL-1-40 led to an improvement in the quality indicators of meat products, since the intensity of metabolic processes in the body directly depends on the feed factor, which is confirmed by the reliable superiority of the experimental group in the slaughter yield of gutted carcasses and the weight of edible parts. In turn, this made it possible to increase the level of profitability of meat production in the conditions of industrial poultry farming.

The paper presents the indicators of feed conversion from the new first-calving daughters of 14 bull producers of two lines of black and motley Holstein breed in the conditions of their breeding in a livestock complex. Groups of analogues were selected. The costs of dry matter, energy exchange, crude protein, physically effective neutral-detergent fiber (physis. NDC), sugar, starch, crude fat and concentrates per 1 kg of milk, milk fat and protein are calculated. In the first calves of the Reflection Sovering line, the production of 1 kg of milk was much less spent than in their peers from the Vis Back Aydial line of metabolic energy, dry matter, nutrients and concentrates. Maximum milk productivity was noted in the daughters of the bull Modifi, in whom the average daily yield (32.3 kg) and the content of milk fat and protein (2.41 kg) were significantly higher than the average on the farm. In the daughters of the bull Alta Depot, on the contrary, the average daily indicators of yield (28.0 kg), milk fat and protein (2.13 kg) were significantly lower. Conversion rates for the production of 1 kg of milk, as well as milk fat and protein, were significantly lower in the daughters of three bulls: Modifi, Aros from the Vis Back Aydial line and Kaminsky from the Reflection Sovering line. For the daughters of these bulls, the cost of concentrates per 1 kg of milk was 287-300 g and was significantly lower than the herd average. The low costs of concentrates per 1 kg of milk fat and protein (3.84 kg) differed only in the daughter of the bull Modifi. Higher costs of dry matter, exchange energy, nutrients were noted in the daughters of the Alta Depot bull from the Vis Back Aydial line. They also spent the maximum amount of concentrates per 1 kg of milk, milk fat and protein, respectively, 333 g and 4.37 kg. According to the results of our research, the best on the farm in terms of conversion exchange of energy, dry matter, nutrients and concentrates per 1 kg of milk, milk fat and protein were the daughters of the bulls Modifi, Aros from the Vis Back Aydial line and Kaminsky from the Reflection Sovering line.
The development of the export potentialof aquaculture in the Novosibirsk region and the importance of preventive measures to prevent the spread of epizootics
Authors: Senina M. A. , Ledeneva O. Y. , Shatokhina Y. P.
Published: July 2024

The development of aquaculture is a priority and significant direction not only in the Novosibirsk region, but also in many other regions of the country. Regions that do not have open access to marine basins compensate for the shortage of fish on the market with the help of neighboring regions or by doing their own breeding in artificial reservoirs. The amount of fish exported in a particular region also reflects the security of the local market. In this regard, the spread of fish diseases is an urgent issue and determines the relevance of measures aimed at ensuring the prevention and improvement of reservoirs. The Ob basin of the Novosibirsk region is recognized as unfavorable for opisthorchiasis, which reduces its economic development and sanitary well-being. Preventive measures should be aimed at maintaining compliance with current standards that ensure the sustainability of economic development and the correction of the epizootic situation. The impact of both internal and external factors on aquaculture enterprises creates certain risks. At the same time, illegal fishing and uncontrolled introduction of products into circulation play an almost decisive role. Indicators of the safety and quality of aquaculture affect the ability of enterprises to provide domestic and foreign markets. Statistical and analytical methods were used for the study, which make it possible to analyze the collected data and the information provided. Updating the information in the register of enterprises certified for the right to export allows specialists of the Rosselkhoznadzor and the Federal State Budgetary Institution “NCBRP” to carry out joint work and interdepartmental activities. It is also worth noting that recently the role and interest of business in investing funds and resources in the development of the aquaculture industry has increased.

Published: July 2024

OBJECTIVE

The authors sought to determine the medical schools with the highest number and proportion of female graduates currently practicing neurosurgery and to identify medical school characteristics that increase female representation in neurosurgery, with the goal of addressing the gender disparity.

METHODS

The authors used the Physician Compare National Downloadable File from the Centers for Medicare & Medicaid Services. Physicians indicating neurosurgery as their primary specialty were extracted. Duplicates, physicians with medical school education listed as "other," and those expected to be in residency, fellowship, or research years (graduation years 2014–2023) were removed. Medical schools with the highest number and proportion of female neurosurgery graduates were stratified. A review of the current literature was conducted to identify characteristics of the institutions with high female representation.

RESULTS

A total of 3486 neurosurgeons (319 female [9.2%], 3167 male [90.8%]) were identified. Yale University (n = 12), Columbia University (n = 8), Johns Hopkins University (n = 8), Stanford University (n = 8), and the University of Maryland (n = 8) had the most female neurosurgery graduates. Schools with the highest proportion of female neurosurgery graduates included the University of California, San Diego (25%); the State University of New York Upstate Medical University (25%); Pennsylvania State University (22.2%); the University of Maryland (21.1%); and the University of Florida (18.4%).

CONCLUSIONS

Achieving gender diversity in neurosurgery necessitates a multifaceted approach. Institutions with a higher number and proportion of female neurosurgery graduates emphasized female-female mentorship, fostered diversity initiatives, and implemented inclusive policies. To increase female representation in neurosurgery, it is crucial to establish robust mentorship programs that provide aspiring female neurosurgeons with the guidance, support, and motivation required to navigate a traditionally male-dominated field.

Published: July 2024

In the context of global climate change, it is of great interest to assess the adaptive capabilities of the glacial relics of the Urals and the prospects for their conservation. Ranunculus kamtschaticus DC. has a high degree of ecological specialization for high mountain conditions and extremely low plasticity. It is preserved in the midlands of the Urals on individual peaks. The life form of R. kamtschaticus in the Ural fragment of its range is a brush-rooted non-turf polycarpic grass with erect assimilating shoots of a non-succulent type. The variability of the development of its shoots and shoot systems under the influence of climatic and weather conditions is shown, the preferential development of shoots with an incomplete development cycle is noted. Irregular fruiting, a long period of germination, and rapid loss of seed germination reduce the competitiveness of R. kamtschaticus in the Urals and its ability to colonize new territories. Threat assessment according to IUCN criteria showed that populations of the species in the Komi Republic and Sverdlovsk region are in critical condition.

Published: July 2024

The generation abundance of peled has been assessed at the lower reaches of the Ob’ River. Based on data on the number of larvae migrated downstream from spawning grounds, obtained in 1981–2021 on the main spawning rivers, current population structure of peled at the lower reaches of the Ob’ River is described, the influence of anthropogenic factors and of the water content of the Ob’ River floodplain on peled reproduction is analyzed. The Severnaya Sos’va River definitely plays a decisive role in the reproduction of peled. In recent years, there has been an increase in the contribution of the Voikar and Sob’ rivers. Seven-year cycles have been identified (between the peaks in the larvae number); their maximums coincide with the peaks of water content at the lower reaches of the Ob’ River with a 1-year lag, which supports the world’s largest river peled population abundance. The presence of such cycles makes it possible to predict phases of high fish abundance. An equation describing the dependence of the generation size of peled at the lower reaches of the Ob’ River on the average water level of Ob’ River in June–August at the Salekhard gauging level in the previous year is proposed.

THE INFLUENCE OF BELT DIRECTION ON THE CONNECTION OF PRECAST COLUMN- BEAMS WITH CFRP SHEETS
Authors: Rante Harmonis
Published: July 2024

The precast beam-column connection method with CFRPs can be developed into an applicable splicing method and environmentally friendly, considering its achievement of 90.6% over monolith joints. The existing weaknesses need to be studied further for the improvement of this connection method. The use of belts with a perpendicular U-shape direction apparently causes the effect of edge stress (scissor force) which actually causes premature failure. This study aims to analyze the influence of belt direction on precast beam-column joints with CFRPs, namely attaching diagonal directional belts to the U-shape. Variations of specimens used are monolith connections (MN) as normal specimens, beltless connections (U1-B0), connections with one belt installed perpendicular to U-shape (U1-B1) and connections with one belt mounted diagonally to the U-shape (U1-DB1). The MN joint achieves a load capacity of 24 kN and deflection of 44.7 mm. U1-B0 reaches 21.75 kN or 90.6% with deflection of 31.36 mm or 70.2% against MN. The U1-B1 reaches 15 kN (62.5%) and deflection is 27.10 mm (60.6%). The U1-DB1 connection reached 26.25 kN (109.4%) with a deflection of 47.16 mm (105.5%) against MN. Changing the direction of the belt to diagonal has improved joint performance, increasing load capacity by 175% and deflection by 174% against U1-B1 and achieving more than monolith joints. With the use of diagonal belts, edge stress still occurs but the process is slower so that the U-shape can last longer. A thicker U-shape is needed to overcome edge stress and this is a part that needs further study.

Published: July 2024

The aim of the study in a pot experiment on Alluvial-meadow soil (Fluvisol, FAO) was to evaluate the effect of different rates and combinations of nitrogen, phosphorus, potassium and silicon fertilizers on the growth of maize (Zea mays L.) an early hybrid Р-8834 from group 310 FAO “Syngenta”. The experiment included 16 variants of fertilization in 3 replications. Data were obtained on the yield of fresh and absolutely dry biomass of maize plants and the content of N, P, K and Si in the dry biomass was assessed. It was found that the concentrations and the export of the studied macroelements with the biomass were significantly influenced by the fertilization applied. Nitrogen export was the highest in the N200, N300 and N400 rate treatments, and in comparison with the export of the other investigated elements. The export of N, P, K, and Si with maize dry biomass corresponded to a significant extent the contents of the macroelements in it. With increasing fertilization rates, not only the content, but also the export of nitrogen, phosphorus, and silicon increased. Regarding the potassium, this tendency was expressed to a less extent.

Abiotic and biotic stresses often impede optimal plant germination by disrupting natural growth and development mechanisms. Gram-negative _Azotobacter_, among crop growth-promoting _rhizobacteria_, emerges as a potent agent for enhancing plant health. _Azotobacter_ employs various mechanisms, such as nitrogen fixation, phosphorus solubilization, pesticide and fungicide degradation, siderophore production, and synthesis of growth-promoting hormones, collectively contributing to improved plant vigor. Furthermore, _Azotobacter_-based biofertilizers offer additional benefits for soil fertility enhancement. As a favorable and cost-effective alternative to chemical fertilizers, the utilization of biofertilizers has gained traction. Nonetheless, commercial-scale microbial biofertilizer formulation remains a challenge. This study aims to consolidate the advantageous attributes and effective research endeavors regarding _Azotobacter_ biofertilizers for fostering sustainable agroecosystems.

Authors: Ardi Nugroho  , Wandi Wijaya
Published: July 2024

This research explored how language, dialogue, and character portrayal in Jane Campion's 2021 film "The Power of the Dog" contributed to the deconstruction of toxic masculinity within the traditional cowboy film genre. Having won several awards, the movie is considered to be a suitable source of data for the current study, especially since it explores the theme of toxic masculinity to some extent. Employing a discourse analysis approach to examine the film's dialogue, clothing, and character interactions, this study revealed how the film challenged stereotypical notions of masculinity associated with strength, stoicism, and dominance. By analyzing specific scenes involving characters like Phil Burbank, the research demonstrated how the film critiqued the emotional repression and violence often linked to cowboy culture. The results also revealed how toxic masculinity and cowboy culture are related and mutually strengthen and maintain the construction of both. This exploration contributed to the understanding of how contemporary films could challenge traditional gender norms and redefine masculinity.

Authors: Ksatria Aldo
Published: July 2024

The objectives of this research are to find conceptual metaphors and their persuasive functions employed by Indonesian President Prabowo Subianto on his speech at the Shangri-La Dialogue 2024. This research utilizes a qualitative descriptive method, grounded in the conceptual metaphor theory (CMT) by Lakoff and Johnson (1980) and the categories of persuasive purposes of metaphors as outlined by Charteris-Black (2018). The research found three types of conceptual metaphors: Important is Depth (orientational metaphor), strategies are tools (ontological metaphor), and trust is a financial asset (structural metaphor). These metaphors serve various persuasive functions, including ideological, empathetic, predicative, and heuristic purposes. The findings may be valuable for those interested in using conceptual metaphors as persuasive tools to engage and influence their audiences.
