Published: December 2020

The cultivation of folk tradition begins in the family, and continues in a systematic and organized way in school as a certainly important task in the education and upbringing of children of junior primary school age. Factors contributing to the realization of this task include: a) school; b) family, and c) other out-of-school factors. Starting from the fact that the cooperation between one’s family and school should be based on partnership, and that learning about traditional folk music requires coordinated action, authors organized a survey aimed at: 1) examining the extent to which the cultivation of musical tradition within the family is reflected on the learning and adoption of related content in music education classes at junior primary school age; 2) determining the extent to which traditional folk music is cultivated in the family by listening to and playing such music; 3) examining the role of family in the process of introducing students to traditional folk music at junior primary school age with regard to other in-school and out-of-school factors. The authors have concluded, teachers believe that cultivating traditional folk music in one’s family is reflected in the form of recognition and improved student motivation for learning content, related to traditional folk music. Students believe that the activity of listening to folk music within family is an insufficiently utilized resource. The survey results confirm the hypothesis that the role of family should be significantly encouraged in relation to other out-of school factors.

This study discusses the features of the transition from the traditional assessment system to the criteria-based assessment in schools of Kazakhstan. The use of criterion assessment in schools in Kazakhstan contributes to the crowding out of traditional methods of assessment and leads to a new vision of the methods and technologies of the system for evaluating educational achievements. In connection with the modernization of Kazakhstan’s education, significant changes are occurring in the control and assessment activities of Kazakhstan schools, its goals, content, and technologies are changing. The problem of assessment activity is one of the most urgent problems both in pedagogical theory and in pedagogical practice. This study presents the results of empirical studies and the features of the transition to a new criteria-based assessment system for Kazakhstan. According to the results of the study, the problem of the need for professional training of future primary school teachers for the criteria-based assessment system was revealed. Results also showed that there are difficulties of applying criteria-based assessment in the practice of primary school teachers. The question of what professional knowledge, skills, and abilities an elementary school teacher must possess to successfully perform the monitoring and evaluation function was investigated. Particular attention is paid to the study of the influence of criteria-based assessment on learning motivation in primary school.

Published: December 2020

In a crisis situation, employees are facing pressures and challenges because they have to deal with unexpected disruption in their routine working conditions with a high level of uncertainty. Organizational communication strategies and practices play important roles to give employees information, direction, and support. The research aims to explore how organizational communication strategies and practices responses to such a specific crisis: Pandemic Covid-19, using a situational crisis communication theoretical framework. The research applies a qualitative approach. Four organizations participated, involved two business organizations and two educational organizations, selected using a maximum variation sampling technique. Four people representing each organization were interviewed using the inductive method. Data were analyzed using thematic analysis. The findings show that organizational communication strategies and practices being used by all participants’ organizations are mostly related to the preparation stage and the response stage of crisis management. Early crisis management planning, forming crisis management teams, and preparing supporting communication systems, including providing health care facilities and communication protocols for infected employees are salient practices during the preparation stage. On the response stage, leader and horizontal communication intensively used with a variation of media and channels. Interestingly, informal communication was minimized while formal communication conducted intensively and transparently. Furthermore, sensitivity to employees’ needs and conditions as well as emphatic communication expressing positive emotion and support was perceived positive to help employees to understand the information well and to feel being understood and being appreciated.

Published: December 2020

The efficiency, accuracy, and replicability of enzyme simulations is often hampered by ad hoc model design. To address this problem, we have developed the Residue Interaction Network ResidUe Selector (RINRUS) toolkit. RINRUS utilizes residue contact networks to automate construction of rational quantum mechanical cluster models. This work examines this problem by computing the reaction kinetics and thermodynamics for 508 models of the active site of catechol-o-methyltransferase, an enzyme which catalyzes the methyl transfer from S-adenosyl methionine cofactor to catechol substrates. Our results demonstrate using RINRUS to rationally design small and accurate active site models.
Mesoporous Silica with Covalently Immobilized Anthracene as Adsorbent for SPE Recovery of PAHs Pollutants from Highly Lipidic Solutions
Authors: Mikhraliieva Albina , Gonçalves Rodrigo Araújo , Zaitsev Volodymyr
Published: December 2020

Two samples of functionalized mesoporous silica containing anchored anthrylmethylamine groups (SiO2-Ant) have been prepared by surface assembling (1) and one step silane immobilization (2). Both adsorbents can be attributed to bimodal balanced hydrophobic-hydrophilic adsorbents with loading of anthracene groups about 15-33%. The adsorbents have been used for SPE of anthracene from organic solvents (acetonitrile, acetone and heptane) and model solutions of lipids (myristic acid and vegetable oil). The obtained results were compared with commercial C18 SPE cartridge. While C18 cartridge recovers anthracene from water-containing media (acetonitrile/water, 1/1), SiO2-Ant cartridges much more efficient in extraction of anthracene from non-polar solvent (heptane). Lipids macrocomponents such as myristic acid and vegetable oil do not decrease the dynamic adsorption capacity and recovery of the model PAH on SiO2-Ant. It was demonstrated that π-π stacking interaction with the analyte determine the selectivity of SiO2-Ant towards of anthracene. This makes SiO2-Ant attractive for selective pre-concentration of PAHs from high lipid content objects, such as vegetable oils.

Electrolyte interaction is of pivotal importance for chemical, biochemical, and environmental processes, including cellular signal transduction, DNA attraction, and protein dynamics. Although its investigation has been at the focus of extensive research, direct visualization of electrolyte interaction at the molecular level is exceptionally challenging. Here, we report a highly sensitive and readily-accessible technique to visualize the electrolyte interactions in water through molecular design and fluorescence spectroscopy. Two water-soluble luminogens with either cationic or anionic groups are designed as electrolyte models. The hydration shell of isolated luminogens is able to restrict their intramolecular motion, which enhances the emission. Consequently, the occurred electrolyte interactions can be optically detected since they affect the reorientation dynamics of water molecules in the hydration shell and vary the restriction strength on the intramolecular motion of the luminogens. Moreover, this technology allows us to reveal how electrolyte interaction affects the internal motion of an electrolyte within its hydration shell, which has rarely been achieved through experimental approaches.

Single-atom catalysts usually comprise positively charged atomically dispersed metal cations on oxide supports. Neutral atoms on oxides are synthetically challenging, and their performance in catalytic reactions remains ambiguous. Here, we shed light on this question with the design of Pd single-atom catalysts on polyoxometalates. Depending on the composition of the support, Pd can either exhibit oxidation states of 0 or 2+. We show that this difference is decisive for the C-O bond hydrogenolysis while displaying negligible effects on the C=O bond hydrogenation. The selective conversion of 5-hydroxymethylfurfural (5-HMF) to 2,5-dimethylfuran (2,5-DMF), a key renewable fuel compound, was shown to occur at 253 K with reaction rates up to 71.0 per hour.

Emerging in late 2019, the SARS-CoV-2 virus has had a devastating health and economic effects around the world forcing governments to enact restrictions on day to day life, resulting in severe economic and social disruption. The virus has stimulated new research in the fields of drug development, vaccinology and diagnostic testing. Here we present the basis for a simple, mass manufacturable saliva based electrochemical assay for the SARS-CoV-2 virus acheived through adsorption of the Angiotsnsin Converting Enzyme 2 (ACE2) into thiolated amphiphobic prefluoro monolayer assemled on a gold sensor surface. Following sensor preparation, it is possible to measure specific binding of recombinant spike protein and discriminate positive and negative samples of inactivated SARS-CoV-2 following 30 minutes incubation under ambient conditions. Representative calculations of limits of detection are made for recombinant spike protein (1.68 ng/ml) and inactivated virus (37.8 dC/mL). The assay as presented ultimately shows discrimination between positive and negative inactivated SARS-CoV-2 samples originating from clinical molecular standards kit intended for clinical and biomedical assay validation, and which is designed to mimic clinical samples through presence of cells and proteins in the sample medium. The simple design of the label free measurement and the selection of reagents involved means the assay has clear potential for transfer onto mass producible units such as screen-printed electrodes similar to glucose-format test strips, to enable widespread, low cost and rapid testing for SARS-CoV-2 in the general population

Inhibitors developed to target the epidermal growth factor receptor (EGFR) are an effective therapy for patients with non-small cell lung cancer harbouring drug-sensitive activating mutations in the EGFR kinase domain. Drug resistance due to treatment-acquired mutations within the receptor itself has motivated development of successive generations of inhibitors that bind in the ATP-site, and third-generation agent osimertinib is now a first-line treatment for this disease. More recently, allosteric inhibitors have been developed to overcome the C797S mutation that confers resistance to osimertinib. In this study, we present the rational structure-guided design and synthesis of a mutant-selective EGFR inhibitor that spans the ATPand allosteric sites. The lead compound consists of a pyridinyl imidazole scaffold that binds irreversibly in the orthosteric site fused with a benzylisoindolinedione occupying the allosteric site. The compound potently inhibits enzymatic activity in L858R/T790M/C797S mutant EGFR (4.9 nM), with relative sparing of wild-type EGFR (47 nM). Additionally, this compound achieves cetuximab-independent, mutant-selective cellular efficacy on the L858R and L858R/T790M variants
In Silico Drug Repositioning Against Human NRP1 to Block SARS-CoV-2 Host Entry
Authors: Gul Seref
Published: December 2020

Despite COVID-19 turned into a pandemic, no approved drug for the treatment or globally available vaccine is out yet. In such a global emergency, drug repurposing approach that bypasses a costly and long-time demanding drug discovery process is an effective way in search of finding drugs for the COVID-19 treatment. Recent studies showed that SARS-CoV-2 uses neuropilin-1 (NRP1) for host entry. Here I took advantage of structural information of the NRP1 in complex with C-terminal of spike (S) protein of SARS-CoV-2 to identify drugs that may inhibit NRP1 and S protein interaction. U.S. Food and Drug Administration (FDA) approved drugs were screened using docking simulations. Among top drugs, well-tolerated drugs were selected for further analysis. Molecular dynamics (MD) simulations of drugs-NRP1 complexes were run for 100 ns to assess the persistency of binding. MM/GBSA calculations from MD simulations showed that eltrombopag, glimepiride, sitagliptin, dutasteride, and ergotamine stably and strongly bind to NRP1. In silico Alanine scanning analysis revealed that Tyr297, Trp301, and Tyr353 amino acids of NRP1 are critical for drug binding. Validating the effect of drugs analyzed in this paper by experimental studies and clinical trials will expedite the drug discovery process for COVID-19.
Bio-inspired Artificial Helical Chromatophore for Stealth Mode
Authors: lee duck weon
Published: December 2020

Stealth technology has been very usefully applied in the military fields and is now becoming more prominent as a strategic technology. In nature, the firefly squid can protect itself from enemies using camouflage as a stealth mode. On the other hand, it is able to send fluorescent signals to attract prey by switching into a bright mode. Despite the development of many existing biomimetic materials, there are significant constraints related to their color-changeable velocity and mobility. Herein, we have developed a bio-inspired artificial thermochromic material system, which can reversibly switch between stealth and bright modes and thus provide a means to adapting to one’s environment analogous to the strategy applied by firefly squids. Through vertical contraction, a helically coiled yarn artificial muscle, selectively coated by Rhodamine B and TiO2, can switch between fluorescent and stealth modes with a maximum speed of 0.31 cm/s. Upon external thermal impulse, artificial thermochromic muscle can spin up to 309° and achieve a negative strain of 84.6%. In addition, this research demonstrates thermochromic effects even in underwater aqueous conditions, showing applicability toward underwater robotics. With the cost-effectiveness of the demonstrated system, the developed artificial thermochromic muscles can be implemented into a variety of applications, such as colorimetric sensors and aqueous color-changeable soft robotics.

Published: December 2020

Arsenic (As) is an environmentally hazardous toxic metalloid. To evaluate As tolerance and assimilation capacity, seedlings of jute (Corchorus capsularis L. var. BJC-7370 and CVE-3), kenaf (Hibiscus cannabinus L. var. HC-95 and HC-3) and mesta (Hibiscus sabdariffa L. var. Samu-93) were grown for 25 days in hydroponic nutrient solution containing four levels of As viz 0, 5, 10 and 15 mg L-1 with four replications. Results were showed that the seedlings of jute, kenaf and mesta were highly potential to tolerate As toxicity. Arsenic had no significant effects on survibility of kenaf, mesta and jute seedlings (var.VE-3). Root and shoot length and dry biomass were decreased with the increasing levels of As. Values of bio-concentration factor indicated the varieties of kenaf, mesta and jute (var.VE-3) were As accumulator. Arsenic accumulation was higher in root than shoot and translocation factor indicated that As is slowly translocated from root to shoot. The rate of translocation is increased with the increasing concentration of As in solution. Highest As contents in shoot (3636.10 mg kg-1) and root (6350.38 mg kg-1) were detected from kenaf HC-3. The highest amount (16.05 mg As pot-1) of As accumulation was also calculated from the variety of kenaf HC-3 with the addition of 45 mg As pot-1. The order of As tolerance and absorption potentiality were kenaf HC-3>mesta Samu-93>jute CVE- 3>kenaf HC-95>jute BJC-7370. These varieties are good cultivar for cultivation and/or phytoremediation of As contaminated environment.

Based on the minerals, mineral chemistry and the geochemistry of the studied rock, the rock is mafic and hydrous minerals formed by hydration recrystallization of pyroxene. The rock has extensively retrogressed but has not been affected by any form of deformation.
GEOLOGICAL ASSISTED ON WATER RESOURCES PLANNING IN MOUNTAINOUS CATCHMENTS IN KUNDASANG, SABAH, MALAYSIA
Authors: Roslee Rodeano
Published: December 2020

Based on geological mapping and geohydrologic data, water resources planning in mountainous catchment areas in Kundasang are outlined. The area is underlain by thick Paleogene clastic sediment and old Quaternary gravels. These rock units are carved by numerous lineaments with complex structural styles developed during series of regional Tertiary tectonic activities. The tectonic complexities reduced the physical and mechanical properties of the rock units and produced intensive displacements and discontinuities among the strata, resulting in high degree of weathering process and instability. The weathered materials are unstable and may cause subsidence and sliding induced by high pore pressure subjected by both shallow and deep hydrodynamic processes. Evaluation of 60 boreholes data in the study area reveals that the depth of the groundwater table ranges from 1.90 m (6 feet) to 11.20 m (35 feet) deep. The groundwater level in the study area fluctuates even within a short period of any instability of climatic change. The Quaternary sand and gravel layers with variable thickness defined the major shallow aquifers within the underlying weathered materials while the highly fractured sedimentary rocks defined the major deep aquifers. Most of the aquifers within the top unconsolidated weathered clastic material are under unconfined condition. The sedimentary formations are coarse-grained clastic materials generally contain fractured porosity and exhibit higher permeability. However, below subsurface, much of the groundwater is partially confined. Movements of groundwater are sufficiently restricted area to cause slightly different in head depth zones during periods of heavy pumping. During periods of less draught, the various groundwater levels will be recovered to their respective original level. This condition resulted from discontinuous nature of sediments where zones of permeable sand and gravel are layered between less permeable beds of silt and clay. Aquifer characterization and geological data are given to assist the local agencies on the water resources planning of the study area.

Published: December 2020

Rock Mass Classification Systems (RMCS) can be of considerable use in the initial stage of a project when little or no detailed information is available. There is a large number of RMCS developed for general purposes but also for specific applications such as Rock Quality Designation (RQD), Rock Mass Rating (RMR), Rock Structure Rating (RSR), Geological Strength Index (GSI), Slope Mass Rating (SMR), etc. In this paper, we present the results of the applicability of the Rock Mass Rating (RMR) System for the Trusmadi Formation in Sabah, Malaysia. The RMR system is a RMCS incorporated with five (5) parameters: Strength of intact rock material, Rock Quality Designation (RQD), Spacing of joints, Condition of joints, and Groundwater conditions. A total of ten (10) locations were selected on the basis of exposures of the lithology and slope condition of the Trusmadi Formation. Trusmadi Formation is Paleocene to Eocene in aged. The Trusmadi Formation generally shows two major structural orientations NW-SE and NE-SW. Trusmadi Formation is characterized by the present of dark colour argillaceous rocks, siltstone and thin-bedded turbidite in well-stratified sequence. Some of the Trusmadi Formation rocks have been metamorphosed to low grade of the greenish-schist facies; the sediment has become slate, phyllite and metarenite. Cataclastic rocks are widespread and occur as black phyllonite enclosing arenitic and lutitic boudins with diameter up to a meter or demarcating thin to thicker fault zones or as flaser zones with hardly any finer grain matrix or as zones of closely spaced fractures. Quartz and calcite veins are quite widespread within the crack deformed on sandstone beds. The shale is dark grey when fresh but changes light grey to brownish when weathered. The RMR system for 10 outcrops ranges from 33.0 to 50.0 and its classified as “Fair” (Class III) to “Poor” (Class IV) rocks. The Fair Rock (Class III) recommended that the excavation should be top heading and bench 1.5 m – 3 m advance in the top heading. Support should be commencing after each blast and complete support 10 m from face. Rock bolts should be systematic with 4 m long spaced 1.5 m – 2 m in crown and walls with wire mesh in crown. Shotcrete should be 50 mm – 100 mm in crown and 30 mm in sides. While for the Poor Rock (Class IV), the excavation should be top heading and bench 1.0 m – 1.5 m advance in top heading. Support should be installed concurrently with excavation, 10 m from face. Rock bolt should be systematic with 4 m – 5 m long, spaced 1.5 m – 1.5 m in crown and walls with wire mesh. Shotcrete of 100 m – 150 mm in crown and 100 mm in sides. The steel sets should be light to medium ribs spaced 1.5 m only when required.

The growth parameters like plant height, number of leaves per plant leaf length and leaf breadth of largest leaf were recorded multiple times with 15 days interval. Days to curd initiation and Days from curd initiation to harvest were recorded by regular field observation. The yield parameters; curd weight with leaves, Marketable curd weight, average curd yield, incidence of hollowing were recorded during harvest. The economics from application of boron doses in cauliflower production was obtained in terms of cost of cultivation, gross returns, net returns, and benefit cost ratio. The result showed that the growth and yield attributing characters of cauliflower were significantly affected by application of boron in which the value of these parameters was found significantly higher in B1 followed by other treatments. The average curd yield of cauliflower in B1 was found to be 12.39 mt/ha which was 48.92% higher than that of B0 with curd yield 8.32 mt/ha. Similarly, the net return was found significantly the highest in B1 and the lowest in B0. The result showed that application of boron in the range of 2-4 kg/ha is preferred to control and higher doses in respect of both productivity and economics.

Fall armyworm is an important pest of maize crop and native of America. Fall armyworm distributed in tropical and subtropical regions of many countries in the World. Eggs, larva, pupae & adults are the 4 stages of life -cycle. Eggs are covered with grey -pink colour layer. Larvae are 35-90mm long in size. The size of male & female pupae are 1.3 to 1.5 cm & 1.6 to 1.7 cm. grey, light brown & silver colour wings are observed in fall armyworm. The larvae of Spodoptera frugiperda larvae feed by scrapping green tissue of leaves & grown up larvae feed large amount of leaf tissues. Window pane like damage should be observed on leaves area. Fall armyworm affects on leaf corn and all sweet tissue part of the maize crop. Deep ploughing before onset of rains & wide sowing practices is best cultural practices for the management of all armyworm. Using of sex pheromone traps @2traps/acre at the time of sowing & hand picking and squashing of eggs are also found effective to control fall armyworm. Spraying of azadirachtin 1 Ec @2ml/liters of water, Emmamectin benzoate 5 SG @0.5g/liters of water, Chlorpyriphos 50% + Cypermetharin 5% Ec. @2ml/liters of water, lambada-Cyhalothrin 5% EC. @2ml/liters of water should be found effective chemical control on armyworm.

The purpose of this experiment is to study the combined effect of frequency of weeding and integrated nutrient management on the growth and yield of transplant aman rice (cv. BRRI dhan49). The experiment consisted of five weeding regimes and four integrated nutrient managements. The experiment was laid out in a randomized complete block design with three replications. The highest grain yield (5.80 t ha-1) was obtained from the interaction between weed free and 25% BRRI RD + 75% N from CD which was followed by the applications of pre-emergence herbicide + one hand weeding at 35 DAT and 25% BRRI RD + 75% N from CD treatment. The lowest grain (3.65 t ha-1) was found from the interaction between no weeding and BRRI recommended chemical fertilizers.The degree of statistical relationship between grain yield and number of effective tillers/hill, grain yield and straw yield of BRRI dhan49 exhibited positive relationship. From the results of the study it can be concluded that the application of 25% BRRI RD + 75% N from CD in weed free condition might be used for obtaining the best performance of BRRI dhan49.

Published: December 2020

With this article, the author continues the cycle of his publications devoted to the problems of proof in pre-trial proceedings in a criminal case. The article considers one of the most controversial procedural methods of establishing the circumstances that are important for a criminal case - forensic examination. The most common methods of collecting evidence in pre-trial proceedings are compared: forensic examination and investigative actions. Its essential features are consistently identified and analyzed, which predetermine its special character and special place in the general system of cognitive techniques that are in the arsenal of the preliminary investigation bodies. As such signs stand out: a) the need to use special knowledge; b) mandatory involvement of an expert as a special participant in criminal procedural relations; c) the need for research and the formulation of expert conclusions; d) complicated criminal procedure form; e) formation of a special means of criminal procedural proof - an expert opinion. Separately, attention is drawn to the rather serious procedural capabilities of an expert, which resemble not so much the rights of participants in criminal proceedings provided for in Ch. 8 of the Criminal Procedure Code of the Russian Federation, how many jurisdictional powers of the preliminary investigation bodies and the court It has been suggested that the opportunity given to the expert to assess the actual soundness of the objects of research and their aggregate sufficiency for formulating certain conclusions, likens him to a kind of scientific judge, that is, the role that the famous German scientist K. Mittermeier predicted more than 150 years ago ... The forensic examination is defined as a very original, to a certain extent even a unique procedural technology aimed at establishing (proving) the circumstances that are important for a criminal case.

Authors:   Irkutsk State University, Makritskaia E. D.
Published: December 2020

The study analyzed some provisions of the Convention on access to information, public participation in decision-making, and access to justice in environmental matters directly related to the right to access to environmental information (in particular, articles 4 and 5 of the Convention, which regulate directly access to environmental information and the collection and dissemination of environmental information, respectively). The components of this right have been studied and described, as well as the main legal terms relating to the law in the text of the Aarhus Convention, such as “environmental information”, “as short as possible”. The work also analyzed and identified those types of information that, based on the provisions of the Convention, relating to environmental information. The paper provides examples of the impact of the Aarhus Convention on the national legislation of some States, as well as a mechanism for implementing the right of access to environmental information in the Republic of Belarus. Based on the study, general provisions on the right of access to environmental information are described, as well as the fact that the language of the Aarhus Convention is widely used in the legislation of States parties to the convention, and the right of access to environmental information itself is integral and multidimensional.
System and Types of Social Services
Authors:   Irkutsk State University, Sinkevich Zh. V.
Published: December 2020

It has been established that, for many years, special legal entities of state and municipal forms of ownership were created as characteristic of the social protection of citizens. In the modern period of development of organizations, the designated relations are associated with the transfer of state functions to legal entities, regardless of their form of ownership and to individuals. This tendency manifests itself in the creation of a system within which small and medium-sized businesses are also involved in the provision of social services. The article presents an analysis of social services from the standpoint of the systemic construction of relations. It is proposed to understand the social service system as the elements resulting in the provision of social services, these relations are regulated by public and private norms. It is concluded that such services are provided by a special subject composition of organizations and individual entrepreneurs, as well as by state-authorized bodies that coordinate these relations, decide to classify citizens as needy. A comparative analysis of the legislative concept “social service system” and its differences from the “system of social services” is offered. Through the analysis of the convergence of private and public principles, the tendency of convergence of the norms of social security and civil law is revealed. It is proposed to consider the types of social services through the features of social services as a special type of service. A comparison of social service legislation and provisions on social entrepreneurship is given. Identifying trends in the development of law, the author concluded that the legislator, by transferring part of the authority to provide social services to subjects of social entrepreneurship, determines the area of responsibility of each subject of relations, develops a mechanism for providing services through a competitive basis of providers of social services. Social services can be provided by any entity, including non-profit organizations. Social services can be provided by any entity, including non-profit organizations.
Organizational Foundations of Social Entrepreneurship: Features of Contractual Structures
Authors:   Irkutsk State University, Filatova U.B. , Ganeva E.O. ,   Irkutsk State University
Published: December 2020

The article is devoted to the research of the Institute of social entrepreneurship. The authors identify the features of the organization of contractual relations in relations mediating the provision of social services. Attention is drawn to the fact that the legislation does not have a unified approach to understanding social services, as well as an exhaustive list of services related to social services. Based on the analysis of current legislation on social entrepreneurship, the article identifies problems related to determining the legal nature of the state (municipal) social order. The authors consider various theoretical approaches to defining the concept of state order. In the doctrine, the state order is considered as a managerial administrative act, as a set of administrative and legal acts, as a task or assignment of the state, and even as a public law institution for implementing the Constitution, laws, and functions of the Russian state in the form of an administrative regime of relations between the state and private law subjects. As a key category that links together all other components of the procurement process, the state order has not found conceptual certainty either in legislation or in legal science. It is proved that a social order by its nature is a private legal act, and the placement of such an order should be considered as a unilateral transaction to provide the authorized body with the right to meet the needs of citizens in social services. At the same time, such a transaction is aimed at organizing relations between state authorities, local self-government bodies and service providers. It is concluded that actions for placing a state (municipal) social order aimed at creating preliminary relations for the provision of social services are a one-sided organizing transaction.
