Published: January 2023

Handicrafts have historically always been practiced in Paraná Coast, Brazil, being a source of income for dozens of families, however this scenario has undergone profound changes with the pandemic of the New Coronavirus (COVID-19), but no studies were found that could reveal the changes caused among artisans as a result of the pandemic. Thus, descriptive exploratory research was carried out with 35 artisans residing on the Coast of Paraná. Women were the majority among the investigated group (65.7%) with an average age of 54 years old. The study revealed that in the perception of the interviewees it is possible to notice the recovery of the impacts caused by the pandemic on the family budget, with the increase in the income obtained from the sale of handicrafts, however in the opinion of the majority of the interviewees (68.57%) the recovery could have been accelerated if there were public policies for easy access to artisans. The study revealed that in Paraná Coast, after the pandemic of the New Coronavirus, there was a reduction in jobs and regional income, and it consequently affected family income and that, in the face of so many deaths, the class of widowed, black or brown women emerged in the investigated sample. The lives of these women are marked by precariousness and they feel more strongly the impacts of segregation due to the need to provide for all family needs by themselves.

Published: January 2023

In search of better comfort and productivity, man has sought information, since antiquity, about civil construction, because, as society has become more complex, knowledge about construction has become an essential skill for human beings. In this context, the present work aims to present a simplified theoretical review on pathologies caused by humidity, and added to these characteristics, to approach ways for possible solutions, seeking to remedy the different problems caused. The present study was written through a bibliographic review on the different problems caused by pathologies caused by humidity, with a focus on solutions. For this, research was carried out on the subject, through a survey of theoretical sources (journals, scientific articles, books, theses, among others) and a theoretical framework that underlies the history of civil construction and the different characteristics acquired over the years. time. Humidity is a pathology that causes some problems in construction and mainly impacts the financial management of the project, as the final value of the work can undergo major changes until the final solution of the problem. Humidity can cause fissures and cracks, compromising part of the construction structure, in addition to other problems that affect aesthetics, such as mold, efflorescence, mildew, blisters in the paint, loss of plaster and rust. As the main causes identified for the appearance of this pathology, we can mention the lack of prevention, since the lack of waterproofing products compromises the quality of the work, causing infiltrations. The lack of ventilation and high humidity in the environment must also be observed, as they generate moisture by condensation resulting in problems such as stains and mold on ceilings and walls. The hydraulic installation is also considered, since it is important that this system has the correct and necessary sealing to avoid contact of water with the structure.
Multiagent LQR-based Control Design and Gain tuning for Quadcopters Fleet
Authors: Martins Araujo Filho Evandro , Da Fonseca Neto João Viana
Published: January 2023

An LQR-based Control design and gain tuning strategies proposals for a multi-agent system are presented in this article, the agents are connected in an undirected graph. Controller gains tuning are adjusted by selecting the Q and R weighting matrices of the Linear Quadratic Regulator. Agreement (consensus) is one of the fundamental problems in multi-agent control, where a set of agents must agree on a joint state value. In the proposed design, first considering that the behavior of the agreement protocol is undirected and static, the main objective is to highlight the complexity of the relationship between the convergence properties of this protocol and the structure of adjacent interconnections. The effects on the formation due to static geometry are analyzed from the resulting data according to the proximity between the agents, where behavior and stability are analyzed based on the desired formation geometry through the construction of the Laplacian matrix.
A Model for Women Representation in the South African National Defense Force: Concealing the Delusion of Femininity and Masculinity
Authors: Mmakola KL
Published: January 2023

This paper presents a model for women representation in the South African National Defence force (SANDF). The dominance of patriarchy and masculinity has frequently jeopardised the representation of women in combat roles in the SANDF. Male military officers have always predominated in the military hierarchy. Since World War I, women, like males, have played vital roles in the military as warriors; nonetheless, they have been marginalised, unrecognised, and underrepresented. The researcher used liberal feminist theory because she thinks that women, like men, have the right to engage in all political and social roles (including war roles) in all political and social roles (including war roles). The qualitative approach and an exploratory research design were used in this study. The population of the study comprised all female military officers in the Limpopo province. Snowballing sampling was used to identify the research participants and a total of fifteen female military officers were selected to take part in in-depth interviews. Data was analysed using thematic content analysis. The study identified elements that impact women's participation in the military as well as the institution's capacity to meet their requirements.. The nature of representation between men and women in the SANDF was found instrumental in concealing the delusion of femininity and masculinity. These findings were instrumental in developing the model for gender representation in the SANDF. The model has four components namely the society, women, government and SANDF. The SANDF is at the centre of the model and the other three components play a pivotal role in naturing the force to ensure gender representation. The study concludes that gender representation in the SANDF can only be achieved if all the three components are considered. Two recommendations were made: the importance of outreach and provision of information.

Demand for Mobile Broadband Use by South African Households: Does Gender Matter
Authors: Mhlanga David , Garidzirai Rufaro
Published: January 2023

Gender equality is crucial to a thriving, contemporary economy that will ultimately benefit everyone in addition to being a fundamental human right. The emergence of the digital era has created new opportunities for the economic empowerment of women and has the potential to advance the cause of gender equality. Internet, digital platforms, mobile phones, and digital financial services may empower women to earn more money, expand their employment alternatives, and gain access to general information and expertise. They will be able to advance past men because they will have access to these opportunities. The goal of the study was to ascertain how gender affected South African household demand for mobile broadband. The findings show that the demand for mobile broadband among South African households is significantly influenced by gender. The data shows that compared to being female, being male increases the probability of needing mobile broadband service. The fact that males had 1.812 times more likelihood than females to pursue mobile broadband may be due to gender-based disparities in the availability of income. In order to increase women's levels of productivity, economic security, and overall quality of life, the study's findings recommend that the government implement programmes to promote their use of mobile broadband. Affordability, a lack of education and skills, and technological literacy should also be at the centre of policy objectives designed to increase women's desire for internet access.

Öffentlichen Parkanlagen wird zu Recht ein hohes soziales Nachhaltigkeitspotenzialzugeschrieben. Als naturnahe Grün- und Freiräume leisten sie einen wichtigen Beitrag zur Lebensqualität in urbanen Siedlungsräumen. Als öffentliche Räume sind sie in heutigen demokratischen Gesellschaften grundsätzlich für alle zugänglich und weisen dadurch ein hohes soziales Integrationspotenzial auf. Die normative Richtlinie allgemeiner Zugänglichkeit bedeutet allerdings nicht, dass de facto keine Ausgrenzungsprozesse in öffentlichen Grünräumen stattfinden. Die vorliegende Studie untersucht, wie Stadtzürcher Quartierparks von Besucher in nen und Besuchern genutzt und wahrgenommen werden und fragt nach gesellschaftlichen Ein- und Ausschlussprozessen. Die Ergebnisse zeigen auf, inwiefern dem Ziel sozialer Nachhaltigkeit Rechnung getragen wird und wo sich Verbesserungsmöglichkeiten eröffnen. Das Buch richtet sich an Personen aus Wissenschaft und Praxis. Es legt dar, welcheMassnahmen der Planung, Gestaltung und Regulierung öffentlicher Freiräume soziale Nachhaltigkeit unterstützen. Die Studie leistet einen wichtigen Beitrag zur wissenschaftlichen Klärung des Begriffes der sozialen Nach haltigkeit sowie zur Erhöhung seiner Praxistauglichkeit.

Background: Metabolic and vascular risk factors (MVRF) are associated with neurodegeneration and poor cognition. There is a need to better understand the impact of these risk factors on brain health in the decades that precede cognitive impairment. Longitudinal assessments can provide new insight regarding changes in MVRFs that are related to brain imaging features. Objective: To investigate whether longitudinal changes in MVRF spanning up to 25 years would be associated with midlife brain volume and cognition. Methods: Participants were from the CARDIA study (N = 467, age at year 25 = 50.6±3.4, female/male = 232/235, black/white = 161/306). Three models were developed, each designed to capture change over time; however, we were primarily interested in the average real variability (ARV) as a means of quantifying MVRF variability across all available assessments. Results: Multivariate partial least squares that used ARV metrics identified two significant latent variables (partial correlations ranged between 0.1 and 0.26, p < 0.01) that related MVRF ARV and regional brain volumes. Both latent variables reflected associations between brain volume and MVRF ARV in obesity, cholesterol, blood pressure, and glucose. Subsequent bivariate correlations revealed associations among MVRF factors, aggregate brain volume and cognition. Conclusion: This study demonstrates that MVRF variability over time is associated with midlife brain volume in regions that are relevant to later-life cognitive decline.

Published: January 2023

The COVID-19 pandemic outbreak was declared by the World Health Organization (WHO) in Wuhan city, China in December 2019 causing several countries to go into lockdown. The lockdown imposed on people affected the country's men's feeding habits and had a financial impact over the globe, especially in the context of developing countries. This study assessed the effects of the COVID-19 epidemic on people's food consumption preferences post the COVID-19 pandemic in Kira Municipality, Wakiso District, Uganda. 

A closed-ended questionnaire was given to households of the selected municipality. Data was analyzed using an independent chi-square test and represented on tables and graphs.

The results showed that food availability, accessibility and utilization were greatly affected by the pandemic leading to change in food consumption preferences and the number of meals per day. The study also found that food consumption preferences were affected by age, marital status, level of education and employment status. Due to limited funding, only a single district was included in the study; therefore, we recommend further studies on food consumption preferences in Uganda for an expanded geographical scope.
Economics of agricultural transport
Authors: Iovlev G.
Published: January 2023

Abstract. The purpose of the study is assess the performance of a variety of different types of vehicles used in agricultural production. Methods. An interpretation of the technical and economic indicators characterizing agricultural transport is proposed, the features of determining the productivity of a tractor transport unit, the cost of one transported ton are considered. Probability theory was used to determine the indicators “Load waiting time”, “Vehicle loading time”. The conditions of operation of vehicles as part of harvesting and transport complexes are considered. Results. Based on the field research, when harvesting corn for silage, the economic efficiency of the use of vehicles was determined. A comparative analysis was carried out using cars and tractor transport units. As a result of the research, it was revealed that for energy-saturated tractors, with tractor trailers corresponding to them in traction properties, the productivity is higher than for MTZ-82 tractors with trailers PST-9 and 2PTS-6 by 2.1–2.3 times than for KamAZ-5511 vehicles by 1.9 times. At the same time, unit costs are lower by 10–-13 % and 5.7 %, respectively. It is recommended that agricultural organizations harvesting fodder crops ensure the optimal ratio of forage harvesters and vehicles; if possible, when transporting green mass, use energy-saturated tractors with appropriate tractor trailers and heavy trucks with trailers. The scientific novelty consists in clarifying and supplementing such technical and economic indicators that characterize the operation of vehicles in agriculture, such as Coefficient of use of working time, Coefficient of use of load capacity, etc. Mathematical dependencies are proposed to calculate these indicators and assess their impact on transport economics.

Published: January 2023

Abstract. The purpose of the work is the studies the world trade in hops and hop products in order to establish the structure of the main shipped products, to identify world market leaders by product type, prevailing world prices and their dynamics over the past five years. Methods. The calculations were carried out by the methods of statistical analysis according to Russian and international official Internet resources. Scientific novelty. The work made it possible to form a list of types of hops and hop products, which are the most important goods imported into Russia and constitute the main burden of foreign hop supplies in domestic imports; to determine the price difference between the importation of products from abroad to Russia and the average prices for their sale in international markets by country, which became the beginning of forecasting potential new suppliers of products. Results. The global hop growing market is mostly represented by crushed and pelleted hop cones (according to 2021 data, they accounted for 60.6 % of the total structure of world exports). It is this product that is predominant in the import of hops in Russia (73.8 % of imports according to data for 2021). The main exporters of these products to Russia were such countries as Germany (64.2 % of Russian imports), Belarus (13.5 %) and the USA (10.5 %). Imported products from the USA were the most expensive for Russia - $24,927/t, shipments from Belarus were the cheapest - $3,563/t. At the same time, shipping prices from the US to Russia are 26 % higher than the average prices for all US exports ($19,821/t). Germany exported products to Russia at a price of USD 10,749/t, which is 7.3 % lower than the average prices of all shipments in the country. Prices for hops from China (6,890 USD/t) and Poland (7,817 USD/t) for Russia are also noticeably lower compared to the cost of shipments of products by counterparties in other countries.

Subsidizing as a factor in the efficiency and innovative development of agriculture in Kazakhstan
Authors: Seitov Sanat
Published: January 2023

Abstract. The existing subsidy payments actually leads to overpricing of resources by suppliers and, as a consequence, to reduction of economic availability for all other agricultural producers, who don’t receive support measures. A limited number of economic entities receive short-term financial benefits from subsidies, which don’t refer to the whole agricultural sector. The purpose is to propose and substantiate recommendations for increasing the economic return on agricultural subsidies in Kazakhstan. Methods. The paper applies a statistical analysis of economic return on agricultural subsidies in Kazakhstan. The work estimates volumes of used resources and produced goods per 1 ruble of subsidies (considering their types). Scientific novelty consists in clarifying approaches to the assessment of economic efficiency of agricultural subsidies; determining the factors restraining the agricultural development in Kazakhstan at the expense of subsidies; proposing and justification of measures to mitigate these factors. Results. The focus of support on short-term results (replenishment of working capital instead of introducing new technologies); the orientation of support on gross indicators instead of production efficiency; insufficient funding for general services in the agricultural sector – are factors that hinder the growth of the returns from subsidies. The article proposes the improvement measures: 1) linking subsidies with production efficiency, application of innovative and environmentally friendly technologies; 2) re-orientation of subsidies in favor of domestic production of resources for agriculture; 3) financing of domestic breeding science, seed production. These measures are based on the need to overcome the technological backwardness of agriculture in Kazakhstan.
Az „osztály halála” Tamás Gáspár Miklós és az értékkritikai iskola szemléletének tükrében
Authors: Kömüves Dániel
Published: January 2023

Tanulmányomban az „osztályok halála” diskurzust, ezen belül is Ulrich Beck kockázattársadalom koncepcióját vizsgálom az értékkritikai Marx-olvasat tükrében. Moishe Postone és Tamás Gáspár Miklós meglátásaira alapozva egy olyan értelmezést mutatok be, amely lehetőséget ad két különböző, a „hagyományos” és az „értékkritikai” Marx közötti különbségtételre. Előbbi kifejezéssel azok az elméletek jelölhetők, amelyek a kapitalizmust a magántulajdonban gyökerező, piac által közvetített osztályviszonyok terminusaiban ragadják meg, illetve az uralom kategóriáját főképp az osztályelnyomás fogalmai mentén határozzák meg. Az értékkritikai nézőpont ezzel szemben az érték és az absztrakt munka kritikai elemzésén keresztül ragadja meg a kapitalizmus struktúráját. Ezáltal olyan absztrakt uralmi formát feltételez, amely az érték és az értéktermelő munka történetileg specifikus társadalmi formáira vezethető vissza. Amellett érvelek, hogy a kései Marx által használt osztályséma elsősorban a kapitalizmus strukturális sajátosságait ragadja meg és nem a különböző társadalmi csoportok szociokulturális aspektusainak, illetve egyenlőtlen viszonyainak feltérképezésére szolgál. Ulrich Beck és az osztály halála mellett érvelők releváns észrevételeket fogalmaznak meg a javak elosztásával és az ehhez kapcsolódó társadalmi jelenségekkel kapcsolatban, e kritikák viszont csupán a hagyományos marxizmusra vonatkoztathatók.
Kölcsönvett életek : Munkaerő-kölcsönzés és elhomályosított osztályviszonyok Magyarországon
Authors: Nagy Ákos , Nagy Klára
Published: January 2023

Tanulmányunk a munkaerő-kölcsönző cégek osztályviszonyokra gyakorolt hatását vizsgálja. Ezt a kérdést a kutatásunkban leginkább elméleti síkon, de statisztikai adatokkal, a munkaerő-kölcsönzők honlapjairól szerzett információkkal és másodlagos szakirodalmakkal támogatva közelítjük meg. A tanulmányunk állításai a következők. Az osztály marxi megközelítése releváns a kortárs társadalmak elemzésében, ha a társadalom anyagi mozgatórugóit és a látszólag fölszámolhatatlan egyenlőtlenségek okait kívánjuk feltárni. Az osztályhelyzet elhomályosítása ebben az elemzésben az osztályellentétek kiélezésének egyik eszköze. A munkaerő-kölcsönző cégeket autonóm kizsákmányoló szereplőknek kell tekintenünk, mivel hármas funkciót látnak el: az osztályviszonyok elhomályosítását, a termelés ingadozásának kiegyenlítő szerepének hatékony ellátását és a tartalékseregből kölcsönzött munkások toborzását. A fizikai munkakörbe kölcsönözött munkások sajátosan kiszolgáltatott helyzetben vannak. Ez a helyzet mutatkozik meg abban, hogy a kölcsönzött dolgozók jellemzően alacsonyan képzettek, segéd- és betanított munkásként dolgoznak és az állampolgári jogaikkal is csupán korlátozottan vagy egyáltalán nem tudnak élni. Tanulmányunkban amellett is érvelünk, hogy a kölcsönzés intézménye az alacsony képzettséget igénylő fizikai munkakörökben dolgozók részére nem biztosít „ugródeszkát” a biztos foglalkoztatásba, kiszolgáltatott helyzetüket a kölcsönzés inkább újratermeli.

Published: January 2023

Theorems of existence and uniqueness of the decision of system of the equations in the private derivatives, representing the generalized mathematical model of processes and devices of preprocessing of crude hydrocarbons are formulated and proved. Generalization gives the chance to apply the principle of unification and typification when de-veloping a method of numerical realization of mathematical models of a class of processes (devices) of preprocessing of crude hydrocarbons, and the proof of the corresponding theorems (an essence —the qua-litative analysis) provides a correctness of application of the generalized model in applied problems of mathematical modeling of studied pro-cesses (devices).

The process of convective transfer of substances during filtration in a po-rous medium (horizontal layer) is considered. An approach to determining the coordinates and action time of a special typeof impulse sources (pollution, heat, explosion, etc.) is proposed, based on the assumption that the latter have no significant effect on the filtration background. For identification, infor-mation about the trajectories (which coincide with the flow lines)of the movement of the impurity substance and the time intervals of the flow of pol-lution from their sources to the corresponding places (points) of observation (detection) is used. It is proposed to identify the coordinates of point sources using characteristic (in relation to the convection equation) functions, a priori information about the movement of pollution, and given coordinates of the nodes of the constructed hydrodynamic mesh. Significant simplifications for the process of constructing the solving algorithm are achieved by replacing the existing model problem of finding the functions of the quasipotential and the flow in complex by the corresponding inverse problem (which, among other things, provides the possibility of effectively constructing ahydrodynamic motion mesh). Its solution is based on the procedure of quasiconformal map-ping of the corresponding quadrangular complex quasipotential domain into a given physical domain. Numerical experiments are presented and analyzed. In particular, it was found that the accuracy of identification of pollution sources depends significantly on the available values of quasiconformity residuals. Their greatest values are achieved on those flow lines that pass through char-acteristic points (so-called «key points») or near stagnant zones. It is possible to reduce the errors generated by the latter, in particular, with a large number of partition nodes. The developed algorithm provides opportunities for its fur-ther transfer to more complex cases of fluid motion,in particular, with addi-tional consideration of the diffusion component, generalization to space, etc.

One of the most common representations of information today are digi-tal images, unauthorized changes of which can lead to negative conse-quences for an individual, institution, firm, and the state as a whole, which makes the detection of digital image integrity violation one of the most ur-gent tasks of information security. The main drawback of the existing ex-pert methods is their focus on detecting the results of a specific disruptive action, but in practice the expert often does not have information about the specifics of an attack on a digital image, while his set of tools is always limited, which can lead to a situation where the investigated digital image is erroneously recognized as original. The first «defense line» here should be methods that are effective regardless of the type of disruptiveaction, i.e. universal. At present, there are a very small number of such methods in open sources; most of them are not free from shortcomings, the main of which is a significant decrease in efficiency in conditions of minor disturb-ances. The aim of the paper is to develop a theoretical basis for an effective universal method of detection of digital image integrity violation, in par-ticular, in conditions of minor disturbances. In the course of achieving the aim of the paper: the justified expediency of using a block approach when organizing an examination of the integrity of a digital image; the area of discrete cosine transformation (DCP) of the block is chosen as the area of examination; justified selection of specific DCP coefficients for organizing the detection of violations of the integrity of digital images, the values of which do not depend on the value of the quality coefficient used when ob-taining the original image, as well as on the specific type of digital images; the difference in the nature ofchanges in the selected formal parameters during re-saving of lossy digital images, depending on whether it is origi-nal or non-original, is investigated. The obtained results of theoretical stud-ies, which are confirmed by the results of computational experiments, con-stitute the theoretical basis for the development of an effective universal method of examination of the integrity of digital images, in particular, in conditions of minor disturbances.

Резюме. Фізичні навантаження сприяють окиснювальному стресу за рахунок утворення вільних радикалів та зниження рівня антиоксидантних ферментів у різних тканинах та органах. Активні форми кисню, викликані фізичним навантаженням, відіграють вирішальну роль у стимуляції сигнальних шляхів для ферментативної активності антиоксидантів. Мета. Визначити особливості оксидантно-антиоксидантної активності периферичної крові у легкоатлетів, які займаються бігом на середні дистанції, в умовах наближеності до жвавих транспортних шляхів та спеціально облаштованих локацій. Методи. Аналіз науково-методичної літератури, обстеження, оцінювання. Результати. Фізичні навантаження призводять до активації процесів, пов’язаних із підвищенням продукції активних форм кисню, продуктів перекисного окиснення ліпідів та стимуляції ферментативної активності антиоксидантів. Ці тенденції зумовлюють адаптацію організму атлета до навантаження. Тренування в умовах впливу негативних екологічних чинників антропогенного походження зумовлює розвиток оксидантного стресу, пов’язаного зі значною продукцією активних форм кисню, дисфункцією антиоксидантної активності та накопиченням токсичних продуктів окиснення. Цей несприятливий стан може призвести до пошкодження компонентів клітин та тканин, оскільки пов’язаний із різними фізіопатологічними станами.

Ключові слова: спорт, фізичне навантаження, активні форми кисню, антиоксидантна система, негативні чинники антропогенного походження.

Published: January 2023

Резюме. Рефідинг-синдром (РС) визначається як зниження рівня фосфору, калію та/або магнію або прояв дефіциту тіаміну, що розвивається від кількох годин до кількох днів після початку надання калорій особі, яка зазнала тривалого періоду недоїдання. Мета. Дослідити сучасні дані про патогенез РС, настанови щодо його діагностики, профілактики та лікування, підвищити обізнаність спеціалістів про виявлення та менеджмент РС. Методи. Огляд сучасних настанов ASPEN щодо діагностики, профілактики та лікування РС. Результати. Визначено, що починати годування осіб, які зазнали тривалого періоду недоїдання, потрібно після визначення рівнів електролітів та ризику розвитку РС. За необхідності має проводитися корекція електролітних змін та обмеження надходження калорій. Спортсмени мають підвищений ризик розладу харчової поведінки, а в деяких випадках, рефідинг-синдром, що обумовлює необхідність в обізнаності виявлення і менеджменту РС.

Ключові слова: рефідинг-синдром, мальнутриція, гіпофосфатемія, розлади харчової поведінки.

Для черліденгу, як складно-координаційного виду спорту, значущими показниками, що дозволяють оцінювати рівень підготовленості спортсменок, поряд з технічними, фізичними складовими визначають і морфологічні, такі як розміри, склад, маса тіла. Мета. Проаналізувати теоретичні та практичні напрацювання і довести значущість морфологічних показників кваліфікованих спортсменок як інформативного критерію управління під час підготовки до змагань у черліденгу. Методи. Теоретичний аналіз та узагальнення даних науково-методичної літератури та мережі Інтернет, систематизація; інструментальні методи визначення складу тіла біоімпедансним методом на вагах-аналізаторах, методи математичної статистики. Результати. В ході дослідження доведено значущість морфологічних показників для моніторингу стану спортсменок у черліденгу в процесі підготовки до змагань. Група спортсменок, які взяли участь у дослідженні, за показниками масо-зростового індексу (BMI) в цілому знаходиться в межах фізіологічної норми, за показником необхідного основного обміну на добу – BMR Ме (25;75) 1554,5 (1479; 1622). Відзначено зв’язок між масою тіла та показником BMR – чим більша маса тіла у спортсменок, тим більший основний обмін на добу. Аналіз компонентного складу тіла спортсменок свідчить, що у всіх співвідношення жирової та активної маси, вміст води знаходяться в межах фізіологічної норми. Асиметрії за всіма показниками по руках не виявлено, виражена асиметрія спостерігається в ногах у всіх спортсменок, яка становить різницю від 400 г і вище. Отримані морфологічні показники дозволили скорегувати підготовку спортсменок, підібрати пару для виступу з урахуванням біомеханічних, психофізіологічних та технічних складових.

Ключові слова: черліденг, моніторинг, аналіз складу тіла, антропометрія, асиметрія, жирова та активна м’язова маса.
