Published: August 2022

Assessing students’ multicultural self-efficacy was a challenging duty for high school counselors, particularly in conjunction with the understanding function of school counseling. The main objective of this development research was to design and validate a scale for measuring the multicultural self-efficacy of high school students. The 851 public high school students from seven regions of Indonesia participated as respondents. After reviewing pertaining literature, the study set 40 preliminary items about cultural insight, communication, cultural value, cultural awareness, and flexibility. A school counselor educator and a high school counselor experienced in the field examined its construct validity and suggested improving item clarity. The revised scale had sequential testing to determine its practicality, validity, and reliability values, namely the practicality test, the pilot test, and the main test. The results showed that 36 of 40 items met the validity and reliability criteria. In addition, most respondents were in significant agreement about the scale practicality. This evidence indicated that this assessment instrument was suitable for measuring the multicultural self-efficacy of high school students.
A Survey of Kenya’s Policies, Institutional Arrangements and Legislation on Traditional Medicine
Authors:   Sifuna & Sifuna Advocates, Sifuna Nixon
Published: August 2022

Traditional medicine (also called ethno-medicine) is indigenous medicine based on traditional medicinal knowledge systems and passed down by word of mouth from generation to generation within the particular indigenous community, especially along familial lines as well as through informal apprenticeships; and which is largely undocumented. For a long time Kenya lacked policies, institutional arrangements and legislation on traditional medicine. Years later that scenario has changed, as the country now has an extensive policy framework and institutional arrangements on traditional medicine, comprising an avalanche of policies and institutional arrangements on the subject. It also has an extensive corresponding legislative framework comprising several pieces of legislation that are scattered over several sectors and line ministries and touching on one or other aspect of traditional medicine. New policies have been made, new legislation promulgated, and some of the then existing legislation amended. The earlier situation, and which has as already stated changed, was perhaps attributable to the nascent stage of traditional medicine policy and legislation at the time. With the effluxion of time, there have been marked developments in Kenya’s policies , institutional arrangements, and legislation on the subject. Notably however, although the effective operation of these institutional arrangements together with that of these scattered pieces of legislation can to some extent promote or impact positively on traditional medicine, they are bedeviled by lack of coordination and harmonization. This paper makes recommendations that if implemented can provide the much-needed coordination and harmonization in Kenya’s policies, institutional arrangements and legislation to ensure effective management and development of traditional medicine.
Open Science Standards at Journals that Inform Evidence-Based Policy

Published: August 2022

Evidence-based policy uses intervention research published in peer-reviewed journals to inform consequential decisions about resource allocation. Because detrimental research practices associated with closed science are common, journal articles report more false-positives and exaggerated effect sizes than would be desirable. Journal implementation of standards that promote open science—such as the Transparency and Openness Promotion (TOP) Guidelines—could reduce detrimental research practices and improve the trustworthiness of research evidence on intervention effectiveness. We evaluated TOP implementation at 339 peer-reviewed journals used to identify evidence-based interventions for policymaking purposes. Each of ten open science standards in TOP was not implemented in most journals’ policies (i.e., instructions to authors), procedures (i.e., manuscript submission systems), or practices (i.e., published articles). Journals implementing at least one standard typically encouraged, but did not require, an open science practice. We discuss why and how journals could improve their implementation of open science standards to safeguard evidence-based policy.
Gamified Inoculation Interventions Do Not Improve Discrimination Between True and Fake News: Reanalyzing Existing Research With Receiver Operating Characteristic Analysis
Authors: Modirrousta-Galian Ariana , Higham Philip Anthony
Published: August 2022

Gamified inoculation interventions designed to improve detection of online misinformation are becoming increasingly prevalent. Two of the most notable interventions of this kind are Bad News and Go Viral!. To assess their efficacy, prior research has typically used pre-post designs in which participants rated the reliability or manipulativeness of true and fake news items before and after playing these games, while most of the time also including a control group who played an irrelevant game (Tetris) or did nothing at all. Mean ratings were then compared between pre-tests and post-tests and/or between the control and experimental conditions. Critically, these prior studies have not separated response bias effects (overall tendency to respond “true” or “fake”) from discrimination (ability to distinguish between true and fake news, commonly dubbed discernment). We reanalyzed the results from five prior studies using receiver operating characteristic (ROC) curves, a method common to signal detection theory (SDT) that allows for discrimination to be measured free from response bias. Across the studies, when comparable true and fake news items were used, Bad News and Go Viral! did not improve discrimination, but rather elicited more “false” responses to all news items (more conservative responding). These novel findings suggest that the current gamified inoculation interventions designed to improve fake news detection are not as effective as previously thought and may even be counterproductive. They also demonstrate the usefulness of ROC analysis, a largely unexploited method in this setting, for assessing the effectiveness of any intervention designed to improve fake news detection.
The role of intolerance of uncertainty when solving the exploration-exploitation dilemma

Published: August 2022

When making behavioural decisions, individuals need to balance between exploiting known options or exploring new ones. How individuals solve this exploration-exploitation dilemma (EED) is a key research question across psychology, leading to attempting to disentangle the cognitive mechanisms behind it. A potential predictive factor of performance in an EED is intolerance of uncertainty (IU), an individual difference factor referring to the extent to which uncertain situations are reported to be aversive. Here, we present the results of a series of exploratory analyses in which we tested the relationship between IU and performance in an EED task. For this, we compiled data from 3 experiments, in which participants received the opportunity to exploit different movements in order to avoid a painful stimulus and approach rewards. For decomposing performance in this task, we used different computational models previously employed in studies on the EED. Then, the parameters of the winning model were correlated with the scores of participants in the IU scale. Correlational and cluster analyses, within both frequentists and Bayesian frameworks, did not provide strong evidence for a relation between EED and IU, apart from the decay rate and the subscale “tendency to become paralyzed in the face of uncertainty”. Given the theoretical relation between EED and IU, we propose research with different experimental paradigms.
Homophobic Bullying as Gender Policing: Population-Based Evidence
Authors: Mittleman Joel
Published: August 2022

Although the policing of gendered embodiment is central to ethnographic accounts of sexual minority bullying, data limitations have prevented population-level analyses of how gender expression shapes bullying victimization. Using novel data on gender expression, the current study documents the dynamics of gender policing in contemporary American high schools. Analyzing population-representative surveys from eight states and ten school districts, I examine how students’ assigned sex, sexual identity and gender expression intersectionally shape their risk for bullying. Consistent with patterns of cultural sexism that stigmatize male “femininity” more harshly than female “masculinity,” I find that gender expression powerfully stratifies bullying among boys but is seemingly unrelated to bullying for girls. Boys who report feeling seen as “very feminine” are three and a half times more likely to be bullied than their “very masculine” peers. By contrast, girls’ bullying rates are roughly constant across the gender expression spectrum. Stratifying by sexuality, I find that highly conforming gender expression offers some protection against bullying for sexual minority boys but no protection for sexual minority girls. Taken together, this study illustrates the value of gradational measures of gendered embodiment and makes newly visible the powerful sanctions pressuring boys into narrow, heteronormative enactments of masculinity.
Hadde jeg bare visst…: Pårørendes behov for informasjon i møte med helsetjenesten
Authors: Sommerseth Rita , Hanssen Helene
Published: August 2022

Universitet i Stavanger, Institutt for helsefag, gjennomførte i 2011 en studie bestående av (1) en pilotstudie (fokusgruppeintervjuer), og en survey (2), rettet mot voksne pårørende til personer over 18 år, som har ulike helsemessige og/eller sosiale vansker. Rapporten har konsentrert seg om følgende områder: • Hvem de pårørende er og hvilke oppgaver de har overfor den de er pårørende til • Informasjon fra hjelpeapparatet til pårørende om helsetilstand og helsehjelp for den de er pårørende til • Informasjon om hjelpetilbud for pårørende I pilotstudien ble to forskjellige fokusgrupper med henholdsvis seks og syv deltagere, intervjuet en gang hver. Deltakerne i den ene gruppen var voksne pårørende til foreldre som hadde rusproblem og/eller psykiske vansker. Den andre gruppen besto av pårørende til personer med et stort spekter av helsevansker. Surveyen, i form av et spørreskjema, ble lagt ut i sosiale medier, slik at informantene i denne studien er pårørende som bruker slike medier. 110 personer svarte på spørreskjemaet og disse representerer pårørende til personer med ulike helseproblemer. En overvekt av de som svarte er pårørende til personer med rusproblemer og/eller psykiske vansker. Når det gjelder informasjon om tilbud om hjelp og støtte til pårørende, viser surveyen at det er de med mastergrad eller høyere utdanning som bruker flest kilder for slik informasjon, blant annet internett, mens for de med grunnskole og videregående skole utgjør venner, aviser og pårørendeorganisasjoner de viktigste kildene for informasjon. For at en skal kunne nå pårørende tidlig, viser studien at det er behov for informasjon som er tilgjengelig fra ulike kilder og på ulike arenaer; Dagspressen er fremdeles en viktig kanal for å nå pårørende, men det er også viktig at lege og annet helsepersonell informerer om at slike tilbud eksisterer, for eksempel ved utskrivelse fra helseinstitusjon, gjerne i form av skriftlig materiale som overrekkes i en utskrivingssamtale. Andre viktige arenaer for informasjon var egen behandler (psykolog) og lærings- og mestringssentra. Når det gjelder forhold som kunne forbedret pårørendes situasjon, er mulighet for jevnlig avlastning for de som har omsorgsoppgaver, sentralt. Dette vil kunne hindre slitasje og bidra til at den pårørende er i stand til å stå i situasjonen. Fokusgruppestudien viste videre at det var viktig for pårørende å kunne stole på at helsepersonell setter seg inn i situasjonen til personen det gjelder, som blant annet å lese journalen, slik at vedkommende for eksempel ikke får medikamenter som han/hun er allergisk mot, eller at andre viktige forhold blir oversett. På den andre siden er det også viktig at helsepersonell ikke opptrer som om den pårørende er utøvende behandler, og for eksempel overøser vedkommende med informasjon eller etterspør informasjon som det er helsepersonellets eget ansvar og holde oversikt over.

UPN “Veteran” Yogyakarta does not apply a sustainable solid waste management system. Waste is only carried out by storing, collecting, and transporting to TPA Piyungan. The purpose of this study was to determine the generation, composition and characteristics of waste and to provide recommendations for sustainable waste management strategies on the UPNVY campus. The method of measuring waste generation and composition refers to SNI 19-3964-1994. Waste characteristics were analyzed by proximate test and ultimate test. The results of the survey and measurements showed that the waste generation at UPNVY was 135.45 kg/day covering Campus I Condong catur at 96.66 kg/day and Campus II Babarsari at 37.79 kg/day. The composition of waste consists of organic waste (24.840%), paper (23.499%), soft plastic (7.450%), hard plastic (5.673%), plastic bag (9.129%), metal (1.294%), glass (1.392%), hazardous waste (0.512%), other waste (9.289%), and residue (16.922%). The proximate test showed that the highest moisture content was in food waste, the highest volatile content and calorific value were found in hard plastic. Meanwhile, the lowest ash content in soft plastic and the lowest fixed Carbon content was owned by plastic bag. For the ultimate test, plastic waste has the highest C and H content. The recommended sustainable waste management strategies are waste reduction and sortation; provision of sorted trash cans, processing of organic waste into compost; and construction of 3R TPS.

The role of effective communication in the process of forming a cohesive and motivated team
Authors: Isaikina Оlena , Navalna Maryna
Published: August 2022

In today's globalized world, the success of any activity depends not only on the professionalism and personal qualities of individual employees, but also on the effectively established relationships of the whole team. The manager's ability to communicate with subordinates and properly build productive relationships with them, the desire of team members to hear each other and take care of successful tasks, ensure coordinated work, where each team member is ready to direct their skills and knowledge to solve common problems. A strong, unified team is the basis for the effective operation of both individual structural elements and the organization as a whole. That is why the problem of effectively established team communication as a key condition for creating a cohesive and motivated team is extremely relevant. Analysis of recent sources of research and publications. Many foreign scholars have devoted their research to the problem of teamwork. In particular, the general problems of teamwork are devoted to the work of J.R. Kemsenber, K. Lewis-McClear, D.K. Smith, M. Taylor. The main directions of development of small groups were studied by B. Tuckman. M. Belbin's works are devoted to the study of the main roles played by team members in the process of their work. V. Voropaiev, Y. Yakutin, L. Kalinichenko, V. Zanora and many other scientists devoted their research to the problem of team management in the context of project implementation. Most of the current work on the study of command systems and models of collective behavior addresses the general problems of team management, but insufficiently addresses issues related to establishing effective communication to form a cohesive and motivated team. The subject of research is the role of communication in team building as an effective tool for forming a professional team. The purpose of writing this article is to identify the features, methods and tools of team communication that are used to convey messages about the coordination of interaction, labor and intellectual efforts of the team and contribute to the cohesion and motivation of team members. The results of the work can find their practical application in the management of modern domestic enterprises and organizations.

In the process of researching the specified problems, the following were taken as a basis: the main provisions of economic theory in the field of regional economy, the work of domestic and foreign scientists and practitioners in the specified field. Work results. The main scientific result of the study consists in the theoretical justification and analysis of the economic development of the region and the peculiarities of the formation of its economic mechanism in the context of transformational transformations of the national economy. Field of application of results. The results of this study can be applied in the field of studying the problems of the placement of productive forces and the regional economy. Conclusions. Summing up, we note that the most modern models of the economic mechanism are models based on the concept of economic equality of all subjects and ownership parties. With such a system of economic relations, the region and the center fall into absolutely equal starting conditions, which sufficiently stimulates both subjects of property relations. On the one hand, thanks to considerable financial and economic opportunities, the center concentrates significant funds on strategically important national directions of social, structural and scientific and technical policy. On the other hand, the regions have enough resources to promptly solve the current problems related to raising the living standards of the region's residents.
THE QUALITY DYNAMICS OF YOUNGER STUDENTS’ MUSICAL SENSORY SKILLS: RESULTS OF THE FORMATIVE EXPERIMENT
Authors:   Бердянський державний педагогічний університет, BARBASHOVA I.
Published: August 2022

The importance of forming primary school children’s musical perception is justified by the introduction of the new version of the educational standard and educational programs as well as by teaching Arts on the basis of an integrative methodological approach. The purpose of the article is to scientifically ground the system of didactic influences on musical perceptual processes of younger school children focusing on the following research tasks: a) to define sensory ability as a unit of functioning of musical perception; b) to characterize the levels of pupils’ musical sensory skills formed in the mass experience of primary education; c) to disclose the specifics of variable experimental effects which differ in the degree of intensity of intermodal connections of sensory channels; d) to compare the quality dynamics of musical sensory skills formation in different versions of the pedagogical experiment. Musical sensory ability is defined as the performance of a system of auditory interiorized perceptual familiarizing and cognitive actions based on the mastered standards of music sounds and skills of applying these standards in the examination of musical phenomena. It has been found that in the mass experience of primary education pupils master musical sensory skills at elementary, intermediate and sufficient quality levels where the intermediate one prevails. The system of exercises and game tasks has been developed on the basis of intermodality with coordination of musical and phonemic auditory, musical auditory and color visual, musical auditory and spatial visual sensory processes. The system is aimed at expanding and systematizing pupils' reference ideas about music sounds as well as forming rational ways of their examining musical phenomena. The effectiveness of the introduced didactic influences has been proved: in comparison with the control group the participants of experimental groups, especially the first one, have demonstrated both the highest efficiency of distinguishing and systematizing music sounds and a variety of skills to reproduce them in singing, spatial modelling and instrumental game. The following changes have taken place in the structure of experimental groups: the respondents with an elementary level of musical perception development have not been identified, but a level gradation with intermediate, sufficient, high and consistently high levels of mastery of musical sensory processes. Key words: musical sensory ability, standards of musical sounds, methods of examination of musical sounds, game tasks, exercises, younger students.

Published: August 2022

In this paper, the optimization algorithm based on the population as improved global particle swarm optimization is described and used for inverse modelling of two-dimensional magnetic field data. This algorithm is able to estimate the parameters of depth, shape factor, amplitude coefficient, magnetic inclination angle and origin point coordinates. To evaluate the efficiency of this method, the magnetic field of an artificial model was analysed, with and without added random noise. The results suggest that the proposed algorithm is capable of model parameter estimation with high accuracy. Accordingly, the improved global particle swarm optimization algorithm was used to analyse the magnetic field of the study area in the Ileh region in Iran located in Taybad city. The study area is very rich in terms of iron resources. The estimate for the study area is that the depth of the buried mass centre is about 114.9 m and its approximate shape is similar to a horizontal cylinder based on the calculated shape factor value which is 1.76. The calculated depth is an acceptable match with the average depth of drillings.

Published: August 2022

La démocratie en entreprise peut être vue comme un processus complexe et incertain visant à partager la souveraineté, mais faisant courir le risque d’une dégénérescence. Cette recherche-intervention met en évidence deux nouveaux risques de dégénérescence, celui d’une radicalisation du débat démocratique et celui d’un délitement du collectif induit par une insuffisance de la souveraineté des individus sur leur travail et leur parcours professionnel. Les auteurs montrent que travailler sur l’activité et ses modalités d’organisation en tenant compte des enjeux de démocratie permet d’atteindre un équilibre global en évitant une recherche directe et incertaine du bon dosage entre représentation et participation.
Quelle souveraineté numérique européenne ?
Authors: Isaac Henri
Published: August 2022

La domination des plateformes numériques américaines et chinoises en Europe a fait émerger une réflexion sur sa souveraineté numérique. En s’appuyant sur les travaux de Michael Mann, il est possible de mettre en évidence en quoi le pouvoir des plateformes numériques constitue une forme de remise en cause inédite de la souveraineté des états. Une approche fondée sur la reconstruction du pouvoir infrastructurel de l’Union européenne est proposée, qui dépasse une démarche actuelle par trop fondée sur le rétablissement d’un pouvoir régalien, insuffisant à lui seul à rétablir la situation.

Purpose: to assess the territory water potential and the efficiency of its actual use for determining the additional water withdrawal volume required for irrigation of under-irrigated serviced irrigation areas. Materials and methods. The assessment of water resources use and distribution was carried out on the basis of actual data obtained from the land reclamation departments for the period 2016–2020. Changes in the area of actually irrigated lands and data on the planned and actual water withdrawal in general and for irrigation were analyzed. Results. An analysis of the summary indicators of water withdrawal quotas and water resources distribution volumes between water management complex institutions was made. A comparison of water resources supply for all needs and for irrigation with the actual irrigation area was made. In 2020, the total water intake amounted to 6.5 cubic km of water. The total water supply from this volume to reclamation systems for all needs amounted to 4.56 cubic km (70 %), and losses – 1.96 cubic km (30 %). 493.7 thousand hectares, which is 51 % of the actually serviced irrigation areas were irrigated. It was determined that for providing the actually serviced irrigation area, it is necessary to supply additional 1.8 cubic km of water for irrigation. Taking into account transportation losses of 30 %, the water volume taken from natural water sources will be 2.3 cubic km, and the total water intake volume is 8.8 cubic km. That is, it is necessary to increase the total water withdrawal by 26 %. Conclusions. According to the results of the studies, the additional water withdrawal required for irrigation of under-irrigated serviced irrigation areas is 2330 million cubic meters, which is 35.7 % of the actual water intake for 2020. When the irrigated land area is brought up to the design values, the shortage of water resources (198.2 million cubic meters) will be observed only in the Chechen Republic.

Purpose: to find out the degree of adaptation of early-ripening soybean cultivars selected by domestic originating institutions to Rostov region conditions during irrigation. Materials and methods. The research was carried out in Oktyabrsky district Rostov region. The object of research is the soybean cultivars Selecta 201, VNIIOZ 31, Olympia and Donchanka. Observations on morphological and biological features of the soybean varieties development under irrigation were made. The studies were carried out according to generally accepted methods. Results. The most productive cultivar Selecta 201 with a yield of 4.3 t/ha was selected. The lowest yield was recorded on the cultivar VNIIOZ 31 – 3.6 t/ha, which is lower than the standard Donchanka by 0.2 t/ha. However, this cultivar is the best in terms of protein content, it exceeds the standard by 2.6 %, and the Selecta 201 variety by 5.8 %. Olympia cultivar selected by the All-Russian Scientific Research Institute of Oilseeds showed an average yield of 4.1 t/ha which is 0.3 t/ha higher than the yield of the standard for 3 years of research. A comparative analysis of the main characteristics of soybean cultivars presented by breeders and obtained in the course of research showed a significant increase in soybean yield under irrigation – by 1.6 times on the Selecta 201 cultivar, more than 3.0 times – on the VNIIOZ 31 cultivar, 2.9 times – on the Olympia cultivar and 1.9 times – on the Donchanka cultivar.

Purpose: selection of soybean varieties adapted to the soil and climatic conditions of Rostov region, taking into account the cultivation technology application on irrigated lands. Materials and methods. Three-year studies were conducted in Oktyabrsky district Rostov region on irrigated lands. Soils under soybean crops are meadow-chernozem heavy loamy. In the experiments, 24 soybean varieties of different ripeness groups were studied. The experiment was carried out in four repetitions with a randomized arrangement of plots. Observations of the soybeans growth and development, yield records, statistical processing of data were carried out according to generally accepted methods of field experiments. Results. The duration of vegetation of the studied soybean varieties ranged from 100 to 125 days. Observations of the growth and development of plants made it possible to determine that, depending on the variety, the height of soybean plants reached 82.9–133.0 cm in the bean-filling phase; during this period, the maximum values of the soybean leaf area duration vary from 38.68 to 84.32 thousand sq. m/ha, and the dry biomass of soybeans varied from 1.31 to 2.31 t/ha. The productivity indicators of the studied soybean varieties on irrigation have been determined. The soybean variety yield varied from 3.19 to 5.34 t/ha. The maximum value was recorded for the variety SK Elana, the minimum was for the variety Kazachka. An analysis of the qualitative composition of soybean grain made it possible to find that the protein content varied from 37.4 to 44.0 %, and the protein harvest was from 1.1 to 1.9 t/ha. The oil content varied from 17.8 to 22.9 % depending on the variety, and its harvest from 0.5 to 1.0 t/ha. Conclusions. Soybean cultivation on irrigated lands allows to obtain high productivity of a wide range of varieties. The maximum yield of soybean grain and protein harvest were obtained from the SK Elana variety – 5.34 t/ha and 1.9 t/ha, respectively. The maximum oil content in the grain was obtained from the Selecta 302 variety – 22.9 %, and its harvest from the SK Elana variety was 1.0 t/ha.

Purpose: to study and analyze resource-saving approaches to irrigation of tomatoes in open ground. Discussion. Tomatoes are one of the most commonly cultivated vegetable crops, as they have high nutritional, organoleptic and dietary properties, beneficial to human health. The problem of increasing tomato production can be solved by introducing scientifically based, experimentally tested cultivation technologies on reclaimed lands, one of the main elements of which is irrigation, which predetermined the relevance of research. Currently, sprinkling and drip irrigation, which have both advantages and disadvantages are used for irrigation of tomatoes. An analysis of features of tomato cultivation with different irrigation methods showed that their production in our country is cost-effective both with sprinkling and drip irrigation. However, the introduction of scientifically based drip irrigation regimes in tomato cultivation can increase significantly their productivity and the values of economic efficiency indicators with economical use of irrigation water. The most effective maintenance of pre-irrigation soil moisture on tomato crops is at the level of 80 % of the lowest moisture capacity. This drip irrigation rate of tomatoes in the open ground is considered optimal; with it the cost of irrigation water for the formation of a product unit is the smallest. Conclusions. The study of the differentiation of drip irrigation regimes of tomato by phases of growth and development of the crop showed that differentiated irrigation with drip irrigation systems in combination with the application of mineral and water-soluble fertilizers provide an increase in tomato yield in open ground, regardless of the region of their cultivation. A promising method for increasing the productivity of tomatoes and optimizing the cost of irrigation water during their cultivation are digital irrigation planning methods.

Purpose: the improvement of the agricultural technology of crop farming on irrigated lands by developing seeder units for soybeans sowing with the simultaneous application of hydrogel granules that can accumulate moisture from soil and give it to plants during the dry period. The hydrogel granules application helps to reduce the risk of plant death under arid conditions, and also increases the inter-irrigation period. Materials and methods. Generally accepted methods were used, and theoretical and field studies of the influence of spring stiffness on the stability of the runner coulter of the developed unit of the seeder were carried out. Results. The manufactured units for the seeder allow to introduce simultaneously hydrogel granules enriched with moisture, and help reduce the risk of plant death in dry conditions, when sowing soybeans and also increase the inter-irrigation period. Ensuring a constant depth of sowing seeds and applying granules is regulated by the fluctuation of the skid-shaped coulter in the longitudinal-vertical position during the operation by changing the spring tension of the opener unit. The degree of spring tension ensures a stable position of the entire system and, accordingly, a constant depth of sowing seeds and hydrogel application. An equation for spring stiffness calculation used in the structure was obtained. Conclusions. As a result of theoretical studies, an equation for the required spring tension with a stiffness in the range from 50 to 60 N/cm was obtained, which ensures the implementation of the technological process and compliance with agro-technological requirements when sowing soybeans and applying hydrogel, taking into account soil density, through the reaction of resistance, as well as the geometric parameters of the coulter.

Purpose: development of recommendations for design and calculation procedure of the flow rate and geometric parameters of fish pass and spawning channels arranged at large river waterwork facilities. Materials and methods. The factual base for the proposed developments were survey materials for the existing Nikolaevsky and Konstantinovsky fish pass and spawning channels and design materials for the Bagaevsky fish pass and spawning channel under construction on the river Don. The development methodology was based on scientific methods of analysis and synthesis of information and technologies for the search design of fish breeding facilities. Results. The survey data of the operating fish pass and spawning canals at waterworks and the analysis of their design solutions made it possible to establish approaches to determining and the ranges of flow rate and geometric parameters, cross-sectional shapes of their tracts and fish recreation areas, as well as approaches to the choice of their layout and design solutions. Taking into account on the basis of the initial information, a general methodology for designing (substantiations, calculations and construction) fish pass and spawning canals and a method for their hydraulic calculation are proposed. When developing general and particular recommendations, known data on the biological features of anadromous-migratory behavior and the fish swimming ability were taken into account. The proposed developments are adapted to the conditions of the proposed layout and design solution of the Kochetovsky fish pass and spawning canal on the river Don. Conclusion. The survey materials of the existing fish pass and spawning canals, arranged at the Nikolaevsky and Konstantinovsky waterworks, as well as the results of the analysis of the design solution of the canal as part of the Bagaevsky waterworks under construction on the river Don. A methodological approach to the development of constructive solutions and methods for calculating the geometric parameters of the fish pass and-spawning channels tracts is proposed.
