RESUMO As organizações são pressionadas pelos stakeholders a promoverem ações sustentáveis, de modo que precisam adotar estratégias que incentivem seus funcionários a apresentarem comportamentos verdes. Assim, objetiva-se analisar os efeitos do treinamento e envolvimento verde no desempenho individual verde, com a interveniência do uso interativo e diagnóstico dos sistemas de mensuração de desempenho (PMS), lógica organizacional para a sustentabilidade e identificação organizacional. Uma survey foi realizada com funcionários de uma geradora privada de energia elétrica, atuante no Brasil, e se obtiveram 101 respostas válidas. Nas análises, utilizaram-se métodos mistos: modelagem de equações estruturais por mínimos quadrados parciais e análise qualitativa comparativa fuzzy-set. Os achados sugerem influência do treinamento e envolvimento verde no uso interativo e diagnóstico do PMS, e desses elementos na lógica organizacional para a sustentabilidade, a qual influencia o desempenho individual verde moderada pela identificação organizacional. Ademais, duas (quatro) combinações entre as condições promovem alto (baixo) desempenho verde individual.
THE THIEF OF TIME AND SOCIAL SUSTAINABILITY: ANALYSIS OF A PROCRASTINATION AT WORK MODEL
Authors: Mosquera Pilar , Soares Maria Eduarda , Dordio Paula , Melo Leonor Atayde e
Published: July 2022

ABSTRACT Although research on procrastination at work is scarce, existing studies indicate its negative effects in multiple spheres of personal and professional life, with repercussions on individuals’ well-being and social sustainability. This study proposes a model that aims to clarify the relationships between the antecedents and consequences of procrastination at work. We follow a bi-dimensional conceptualization of procrastination at work, using the dimensions of soldiering and cyberslacking. The model includes boredom at work as a predictor and work stress and job satisfaction as outcomes. Data from a sample of 287 participants were analyzed with Partial Least Squares. Results show that boredom at work is positively associated with both soldiering and cyberslacking. Results also show that soldiering increases work stress and decreases job satisfaction. Cyberslacking has no significant effects on work stress or job satisfaction. The theoretical and practical implications of this study are further discussed.
Renewable Technology Adoption Costs and Economic Growth
Authors: Adao Bernardino , Narajabad Borghan , Temzelides Ted
Published: July 2022

We develop a dynamic general equilibrium integrated assessment model that incorporates costs due to new technology adoption in renewable energy as well as externalities associated with carbon emissions and renewable technology spillovers. We use world economy data to calibrate our model and investigate the effects of the technology adoption channel on renewable energy adoption and on the optimal energy transition. Our calibrated model implies several interesting connections between technology adoption costs, the two externalities, policy, and welfare. We investigate the relative effectiveness of two policy instruments-Pigouvian carbon taxes and policies that internalize spillover effects-in isolation as well as in tandem. Our findings suggest that renewable technology adoption costs are of quantitative importance for the energy transition. We find that the two policy instruments are better thought of as complements rather than substitutes.
Physiotherapy for individuals with HTLV-1
Authors: Gomes Lima Tambon Lucynara , Nunes Sá Katia
Published: July 2022

CONTEXT: Individuals with HTLV-1 have dysfunctions that directly impact their quality of life. Physiotherapy uses resources that help a lot in the treatment of these changes. However, questions are asked about which modalities are most used and whether they are being properly applied. The only certainty is that the more we know about the physical therapy resources used in individuals with HTLV-1, the better the result of the treatment used. How, then, is this scientific scenario?

Authors: YIKILMAZ Hanifi , GÜMÜŞDAĞ Hayrettin , BASTIK Canan
Published: July 2022

Aim: The aim of this study is; determination of the satisfaction level of the users of Semi-Olympic Indoor Swimming Pool owned by the Yozgat Youth and Sports Directorate and investigation of quality of their life. 299 volunteers that use swimming pool in October, November and December 2018 participated in the Research. Research methodology: In this study, descriptive research model was used to determine demographic characteristics, quality of life and satisfaction levels of the participants. Relational research model was used to examine the relationship between the quality of life and satisfaction levels of the participants. The data obtained from the study were transferred to SPSS 22.0 package program. In the process of data analysis; in order to describe the demographic characteristics of the participants frequency analysis is used, independent groups t-test is used for binary groups, and one-way variance analysis, ANOVA analysis, is used for three or more groups. Pearson's correlation test was performed to determine the relationship between two variables (Sports Facilities Satisfaction and Quality of Life). The level of statistical significance was determined (p> 0.05) in the tests. Findings: According to the findings, men use the facility more than women, men are more satisfied than women, women have lower quality of life than men in general, and there is a statistical difference between income status and satisfaction variables. Research limitations: The study group consists of users of the Yozgat semi-Olympic swimming pool in December, November and October 2018. It will be more productive to work on more pool users and for a longer period of time. Practical implications: High relationship between the quality of life sub-dimensions was observed positively, although the High relationship between the quality of life and the satisfaction of the facility was not observed positively. In addition, a higher correlation was observed between physical health and facility satisfaction than others. Originality/Value: This study is considered valuable as an example since there is not enough research between satisfaction of pool users and their quality of life.

(EG), in addition to regular volleyball training, static and dynamic core training was performed 3 times a week for 30 minutes for 8 weeks. While (CG) only weekly regular volleyball training was applied. Pre-test measurements (balance, vertical jump, agility and flexibility) of both groups were performed before the studies. At the end of 8 weeks, the last test measurements of the groups were taken. To compare the pre and post values of the groups separately (2x2) repeated ANOVA was used. Results: The first and last test measurements of the groups were compared between the groups; According to the analysis of the data, a statistically significant difference was observed in the measurement values of the balance test, vertical jump test, agility test and flexibility test (p<0.05). Conclusion: In addition to regular volleyball training, dynamic and static core programs applied within the scope of conditioning studies contributed positively to some measured motor development characteristics of the athletes.
Quality control analysis for 10X snRNA-seq v1
Authors: Jacobsen Daniel
Published: July 2022

Here we describe a computational protocol for performing quality control analysis on shallow sequencing data obtained from 10X snRNA-seq experiments. The workflow starts with raw MiSeq run folders and uses cellranger to generate count matrices. The raw count matrices are analyzed and sequencing saturation plots are generated. The saturation plots are then compared against plots from a reference set of libraries with varying qualities (bad, fair, good, great), thus allowing for the determination of sequencing requirements as well as an assessment of the overall quality of each 10X snRNA experiment.

Políticas de inclusión de estudiantes con discapacidad en contextos de pobreza: un estudio socio-pedagógico en Buenos Aires.
Authors: Schwamberger Cintia
Published: July 2022

A partir de un trabajo de investigación cualitativa, este artículo tiene como objetivo la descripción de los procesos de inclusión educativa de estudiantes con discapacidad en contextos de pobreza urbana. Desde un enfoque descriptivo se recuperan las voces docentes de una escuela de educación especial ubicada en un distrito escolar de la Región Metropolitana de Buenos Aires (RMBA). Como hipótesis se sostiene que las políticas de inclusión se configuran como dinámicas de inclusión excluyente. Los principales resultados indican que las condiciones materiales y de asignación de recursos que tienen las instituciones se transforman en uno de los obstáculos más profundos para garantizar trayectorias escolares justas y de calidad. Esto, a su vez, se traduce en prácticas excluyentes y degradantes hacia estudiantes con discapacidad que habitan estos contextos.
Principles of Solving the Symbol Grounding Problem in the Development of the General Artificial Cognitive Agents
Authors:   Artificial Intelligence Agency, Moscow, Russian Federation, Dushkin R. V.
Published: July 2022

The article describes the author's approach to solving the problem of symbol grounding, which can be used in the development of artificial cognitive agents of the general level. When implementing this approach, such agents can receive the function of understanding the sense and context of the situations in which they find themselves. The article gives a brief description of the problem of understanding the meaning and sense. In addition, the author's vision is given of how the symbol grounding should occur when the artificial cognitive agent uses sensory information flows of various modality. Symbol grounding is carried out by building an associative-heterarchical network of concepts, with the help of which the hybrid architecture of an artificial cognitive agent is expanded. The novelty of the article is based on the author's approach to solving the problem, which is represented by several important principles — these are multisensory integration, the use of an associative-heterarchical network of concepts and a hybrid paradigm of artificial intelligence. The relevance of the work is based on the fact that today the problem of constructing artificial cognitive agents of a general level is becoming more and more important for solving, including within the framework of national strategies for the development of artificial intelligence in various countries of the world. The article is of a theoretical nature and will be of interest to specialists in the field of artificial intelligence, as well as to all those who want to stay within the framework of modern trends in the field of artificial intelligence.

Authors: Padrul M. M. , Isaeva N. V. , Cherkasova E. V. , Berseneva S. N.
Published: July 2022

Objective. To conduct epidemiological studies of the long-term dynamics of maternal mortality (MM) and failed maternal mortality, development of trends and territorial distribution.

Materials and methods. The data of official statistics on maternal mortality calculated for

100 000 live births and a long-term dynamics of unrealized maternal mortality according to the data of the Ministry of Healthcare of PK "Unified Information System of Healthcare of Perm Krai" are presented. The number of cases of complicated pregnancy, childbirth and the postpartum period with the formation of multiple organ dysfunction or insufficiency requiring intensive therapy, blood transfusion and emergency surgical interventions was calculated. The epidemiological descriptive and evaluative method was used when performing the studies. The long-term dynamics of MM was calculated, the rectilinear epidemic trend for the function of the parabola y1 = a + bx and the curvilinear tendency for the function of the parabola y2 = a + bx + c2, its upper and lower confidence bounds (Me 0.95) were determined. The rate of growth and increment were investigated and the research cyclical fluctuations were determined.

Results. The maximum level of maternal losses (ML) in Perm Krai established in 2003 was 44.2 per 100 thousand live births. The minimum figure in 2015 was 5.2 per 100 thousand live births. The average long-term indicator of MM is 19.3. A feature of the long-term dynamics of the studied period was a steady decline in MM with an average annual rate of 5.7 %. Cyclical fluctuations were initially regular in nature, and subsequently had a lengthened rhythm of 13 years. Failed maternal mortality in Perm Krai had a pronounced downward trend; the decrease rate was 518.9 %. The annual loss rate was 69.8 %.

Conclusions. The long-term dynamics of MM in Perm Krai was characterized by an average degree of intensity, an epidemic tendency to decrease, the presence of cyclical fluctuations, the formation of internal causes testifying to the possible activation of maternal losses. The long-term dynamics of failed maternal mortality had a pronounced downward trend.
Electrocardiographic and cardiobiochemical reactions in patients with closed chest injury
Authors: Vakhrushev D. S.
Published: July 2022

Objective. To study the electrophysiological and clinicobiochemical characteristics of cardiovascular system in closed injury of the chest.

Materials and methods. There were examined 114 persons diagnosed the closed chest injury, who were admitted to the Thoracic Unit of City Clinical Hospital №9 in Izhevsk. The causes and mechanisms of injuries, the data of clinical and functional methods of investigations of cardiovascular system, the data of case histories and previous preventive examinations were analyzed. The comparison group involved 50 practically healthy men.

Results. The mean age of the persons in the main group and the comparison group was 45.9 12.8 years and 44.7 11.5 years, respectively. The prevailing causes of injury were the following: road accident 17 persons (14.9 %), fall from a height (higher than ones own height) 32 persons (28.0 %), fall from a height of ones own height 37 persons (32.5 %). The increased values of the markers of myocardium damages and inflammatory reaction as well as the changes in electrocardiographic parameters were established among the examined persons.

Conclusions. The closed chest injury occurs mainly in the able-bodied population that, of course, is an actual factor for a possible unfavorable labour prognosis. When analyzing the ECG parameters and cardiometabolic characteristics, there were detected the deviations earlier absent in these patients and in patients of the comparison group, which showed the myocardial damage.
Finite-Difference Simulation for Infrasound Generated by Finite-Extent Ground Motions
Authors: Kim Keehoon , Bowman Daniel C. , Fee David
Published: July 2022

Underground explosions can produce infrasound in the atmosphere, and the wavefield characteristics are often governed by the ground surface motions. Finite-difference methods are popular for infrasound simulation as their generality and robustness allow for complex atmospheric structures and surface topography. A simple point-source approximation is often used because infrasound wavelengths tend to be large relative to the source dimensions. However, this assumption may not be able to capture the complexity of explosion-induced ground motions if the surface area is not compact, and appropriate source models must be incorporated into the finite-difference simulations for accurate infrasound prediction. In this study, we develop a point source representation of the complex ground motions for infrasound sources. Instead of a single point source, we use a series of point sources distributed over the source area. These distributed point sources can be equivalent to air volume changes produced by the ground motions in the atmosphere. We apply the distributed point-source method to a series of buried chemical explosions conducted during the Source Physics Experiment Phase I. Epicentral ground-motion measurements during the experiments provide a way to calculate accurate distributed point sources. We validate and evaluate the accuracy of distributed point source approach for infrasound simulations by direct comparison with acoustic observations in the field experiment.
Economic Effects of US-China Decoupling on Global Value Chain
Authors:   Korean Academy Of International Commerce, Inc., Cho Jung-ran , Lim Byeong-ho
Published: July 2022

Purpose : US policy towards China now focuses on decoupling. Due to decoupling, the supply chain based on the existing global value chain (GVC) will have to be adjusted to a large extent, and the production network in Asia, centered on China, will be reorganized.
Research design, data and methodology : This paper is the first to quantitatively estimate the effect of the US decoupling policy. Decoupling will seriously hit the backward and forward linkages of China's GVC, but US GVCs will not be significantly affected.
Results : Due to decoupling, Korea’s exports of intermediate goods to China will likely be greatly reduced, and value-added exports will decrease by US$65.7 billion to US$120.5 billion.
Conclusions : The GVC impact analysis in this paper shows Korea should seek an active industrial policy to strengthen forward linkages while minimizing backward linkage losses.

Purpose : This study finds the direction in which the export of K-contents can be further activated in the Southeast Asian market through the combination and evolution of the metaverse and its contents.
Research design, data and methodology : This study approaches the concept, technical theory, and business perspectives of the metaverse through previous studies. In addition, data related to K-contents are divided into one domain for contents and another domain for service trades, with research focused on a literature search.
Results : K-contents and the metaverse require a segmentation strategy that provides K-content experience opportunities to global content fans through the establishment of a content system.
Conclusions : Exports of K-contents are expected to become more active and extensive in the Southeast Asia market, and will become a new business model in which the real and virtual worlds converge.
Requirements for an Effective Switch B/L: Focusing on The KSC Docket No.2018Da249018
Authors:   Korean Academy Of International Commerce, Inc., Lee Won Jeong
Published: July 2022

Purpose : A Switch B/L refers to a bill that is issued as a substitute for an original B/L but which is not identical in all respects to the bill that it is replacing. In Docket No.2018Da204018, there was a dispute as to the validity of switch B/L which was issued by the freight forwarder at the request of the intermediary without authority from the original B/L’issuer as the carrier. The supreme court of Korea ruled that this B/L can not be regarded as valid B/L under the Korean Law. This article analyses Docket No.2018Da204018 according to the English law, and proposes some recommendations for the carrier, when he issues the switch B/L.
Research design, data, methodology : This article adopts the legal methodology which utilizes textbooks, journal articles, electronic resources, UK COGSA(1992), and several cases from the English court.
Results : This article finds that, under the English law, three requirements for an effective switch B/L are a proper requester, a proper issuer, and a legitimacy reason for issuing the switch B/L. Thus, this article concludes that the switch B/L in Docket No.2018da204018 shall not be recognized as a valid B/L, because it clearly lacked the second requirement naming a proper issuer.
Conclusions : The carrier potentially has greater liability over issuing the switch B/L than the requester. Therefore, when issuing the switch B/L, it is crucial for the carrier to verify the requester, obtain a legitimacy reason for issuing the switch B/L, and to insist upon surrendering the original B/L..
A Study on Structural Problems in the Application of Federal and State Laws in the US Marine Insurance Law
Authors:   Korean Academy Of International Commerce, Inc., Park Se-hyun , Han Nak-hyun
Published: July 2022

Purpose : The purpose of this study analyses the structural issues in the application of Federal and State laws in the US Marine Insurance Law.
Research design, data and methodology : The methodology is a typical case law analysis dealing with the issues surrounding the selection of the applicable law for marine insurance contracts as the issues implied by the US Marine Insurance Law.
Results : In Travelers v. Ocean Reef, the 11th Circuit Federal Court of Appeals stated that only the Supreme Court had the privilege of overturning its decision and, unlike some commentators, could not dismiss Wilburn Boat on the grounds that it might disagree with Wilburn Boat. In Travelers v. Ocean Reef, will prove fascinating enough to tell you what the Supreme Court thinks about Wilburn Boat today.
Conclusions : Considering the possibility that the law of the United States, which is popularly referred to as a major power in litigation, will affect Korea's trade officials, it is even more so. In addition, although the problem of the marine insurance law in the United States is recognized as a domestic problem, it should be recognized that the effect of opacity of the law and the diversification of legal principles is international.
Efficiency in Customs Capacity in Developing Countries by the Korea Customs Service
Authors:   Korean Academy Of International Commerce, Inc., Kwon Seung-Ha
Published: July 2022

Purpose : The aim of this article is to develop customs-capacity cultivation programs for the Korea Customs Service in developing countries and to present efficiency measures for providing long-term and systematic programs with expertise.
Research design, data, and methodology : Prior to the outbreak of COVID-19, the Korea Customs Service reviewed the status of customs-capacity cultivation support in developing countries and analyzed the form of international organizations' support for developing countries. The Korea Customs Service proposed measures to streamline customs-capacity cultivation programs in developing countries.
Results : In order to streamline customs-capacity cultivation programs in developing countries, the Korea Customs Service proposed preparing a long-term organizational system and pre-demand surveys, and proposed developing customized programs for each country with follow-up management.
Conclusions : Although Korea's customs-capacity cultivation program in developing countries is trying to overcome the limitations of existing programs, it is difficult to secure expertise because the person in charge is not determined according to each program, subject, and target. Therefore, it is necessary to apply efficiency measures in consideration of the establishment of an organizational system from a long-term perspective, as well as pre-demand survey of programs, development of customized programs, and follow-up management.

This article studies the level of operationalization and the streamling of public administration management practices, while trying to identify constraints and assessing improvement plans. Theoretical Frame: The foundations of the study make it possible to balance the theoretical, empirical and scien- tific aspects of NPM. On a theoretical level, it offers a scope of analysis of new public management practices. We will also consider the doctrinal ap- proaches and principles in close relation to the school setting. Recommended Methodology: Our research methodology is an exploratory descriptive study, the data collection instruments are mainly the documentary study, the anal- ysis of management practices of the people involved and the stakeholders of the establishment. It is based on the government program model which is built on 4 components: management autonomy, evaluation, institutional openness and management capacities support. Results: The results show that the improvement of schools requires the implementation of a managed, controlled and dynamic steering system that is oriented towards the search for organizational performance. This improvement would be through the integration of NPM practices that aim to optimize performance through pri- vate sector practice.
Teacher Professionalization and Training Management: What Job Reference(s) and Professional Skills in a Real Work Situation?
Authors: Choukrallah Mohamed
Published: July 2022

Professionalization seems to have a positive impact in the construction of professional identity, in the sense that its process constitutes a powerful integrative vector for future teachers in the socio-professional context. The study would analyze the constraints that hinder this process of university professionalization at the ENS of Casablanca, among students of the third year "professional license: Teaching of physical education and sports" in a situation of pedagogical internship. Through a quantitative descriptive methodological survey approach based on a questionnaire designed through the literature review, we targeted a sample composed of 120 students – trainees (58\% students / 42\% students), 30 tutors in internship and 20 trainers. The variables evaluated are the hourly volume of internships, the teaching skills of student-trainees, the coordination between the actors in internships, the supervisory skills of tutors in internships, the modalities of training and socio-professional support. The data is analyzed by an analysis of variance. Our results showed the insufficient hourly volume devoted to the internship and the negative influence of the heterogeneity of skill levels between trainees (intragroup) on socio-professional construction, as well as the lack of coordination between internship actors and the lack of basic skills among trainees and tutors in internship in terms of teaching and supervision that hinders the process of professionalization and collective construction professionalizing. We retain through this study that professionalization is multifactorial in its process of operationalization. It is necessary to overcome all the constraints that hinder this approach for cost-effective and integrative training.
Comparison of microanatomy of ascending aorta and pulmonary trunk with age: A cross-sectional study
Authors: Alex Reba Babu , Kalyanikuttyamma Lathi Kumari , Sudhakaran Manju
Published: July 2022

Cardiovascular disease (CVD) accounts for the leading cause of mortality worldwide and it has a strong association with age. Aging brings about structural and functional changes in vessels, culminating in CVD. This study aims at determining and comparing the structural age changes in the two great vessels of heart, ascending aorta (AA) and pulmonary trunk (PT).

Human ascending aorta and pulmonary trunk samples were obtained during autopsy from 55 individuals of different age group. After processing, they were stained with eosin haematoxylin and special stains to identify connective tissue fibres and smooth muscle cells. Thickness of each tunic of the vessel wall, full wall thickness, quantity of smooth muscle cells and severity of fragmentation of elastic fibres were detected.

In all age groups, PT was thinner than AA. Average full wall thickness of AA was greatest in the sixth decade of life while that of PT in the fourth decade. Elastic fibres were long, straight and arranged in a lamellar pattern in tunica media of both the vessels in fetal life. They underwent fragmentation from first decade of life in PT and from third decade in AA. Grade5 fragmentation was noticed only in PT. Degeneration of smooth muscle cells occurred in both the vessels with age, but was very little in PT.

Both the great vessels showed degenerative changes with advancing age, but after the first decade of life, the changes were very less in PT when compared to AA.

Michael condensation of 2-(4-carboxybenzylidene)-3,4-dihydronaphthalene-1(2H)-one with methylene active compounds in the targeted synthesis of O-heterocyclic hybrid systems
Authors:   Saratov State University, Kanevskaya Irina V. , Ivanova Aleksandra L. ,   EPAM Systems, Pchelintseva Nina V. ,   Saratov State University, Fedotova Olga V. ,   Saratov State University

Approaches to the design of new hybrid polyoxaheterocyclic compounds based on the interaction of 2-(4-carboxybenzylidene)-3,4- dihydronaphthalene-1(2H)-one with methylene active compounds of the 2H-chromen-2-one series – 3 -(1,3-dioxobutan-1-yl)-2H-chromen- 2-one and 4-hydroxy-2H-chromen-2-one, as well as their carbocyclic analogue – 1,3-indanedione under various conditions have been considered. It has been revealed for the first time that during the reaction of the studied chalcone with 3-acetoacetyl-2H-chromen-2-one in a piperidine medium, followed by treatment with acetic acid, the hybrid acetate 7-(4-carboxyphenyl)-8-oxo-5,8-dihydro-6H-benzo[h] chromeno[3,2-b]xanthylium is formed. It has been found that the formation of such a hybrid structure with the participation of 1,3-indanedione in the Michael condensation as the methylene component under similar conditions is not possible. In this case, the competitive nucleophilic addition of piperidine at the arylidene fragment with the formation of 4-((1,2,3,4-tetrahydro-1-oxonaphthalen-2-yl)(piperidin- 1-yl)-methyl)benzoic acid is predominant. It has been shown that the condensed adduct of arylidene dihydronaphthalene-1(2H)-one with 1,3-indanedione arises by refluxing the reagents in pyridine. The use of hydrochloric acid in the isolation of the reaction product contributes to the aromatization of the resulting dihydrochromene ring, which ultimately leads to the chloride 7-(4-carboxyphenyl)-8-oxo-6,8-dihydro- 5H-benzo[h]indeno[1,2- b] chromen-13-ilium. A similar trend is observed when 4-hydroxy-2H-chromen-2-one is introduced into the transformation under study. It has been found for the first time that when the reaction is carried out in glacial acetic acid with the addition of piperidine as a catalyst, the latter also acts as an azanucleophile and competitively binds to the reaction center of the substrate. Replacing the solvent with pyridine leads to the formation of a hybrid system, 4-(6-oxo-8,9-dihydro-6H,7H-benzo[h]chromeno[4,3-b]chromen-7-yl)- benzoic acid. In this case, salt formation after treatment with hydrochloric acid is not observed. Thus, in the course of the study, a new synthetic approach to the formation of hybrid chromene, xanthene systems has been considered. The observed salt formation can be the factor in increasing the bioavailability of newly synthesized compounds.

Molecular imprinting is a rapidly developing and promising approach for the selective recognition for target molecules of different nature. In this review, we have collected works devoted to synthesis and application of polyaniline-based molecularly imprinted polymers (MIPANI) over the last 5 years. The manuscript provides brief descriptions of the main approaches to the synthesis of PANI MIPs and the advantages and disadvantages of each technique. We also discuss the effect of various factors on the process of MI-PANI synthesis, including polymerization methods, molecular weight of template molecules and the types of scaffolds. The analytical characteristics of the resulting sensors are also provided. Thus, it can be concluded that polyaniline is a very promising material for MIPs synthesis.

Unlike antibiotics and heavy metals, nucleic acids exist in the aquatic environment as a part of prokaryotic and eukaryotic microorganisms (bacteria, fungi, etc.) rather than in a free form. In this regard, the most important primary stage of sample preparation of an object for the quantitative analysis of DNA and RNA in natural and wastewaters includes membrane ultrafiltration of an aqueous sample, followed by its sorption preconcentration on a solid phase carrier. The efficiency of ultrafiltration and subsequent sorption of nucleic acids from natural and wastewaters largely depends on the material of filters, membranes, and sorbents. Polymeric materials are widely used due to their special properties: the affinity of polymers for biological objects, the ability to create pores of any required size, good mechanical properties and resistance to the extraction of microorganisms captured. The paper reviews the 15-year-old scientific literature on filtering, membrane and sorption polymeric materials used to extract nucleic acids from aqueous media and preserve them. Polymeric sorbents for collecting and concentrating DNA and RNA from the liquid phase, as well as storing nucleic acids, are covered. It has been found that ultrafiltration is used at a relatively low concentration of the analyzed object, followed by extraction of the substance using commercially available kits, including cartridges. Sorption (solid-phase concentration) is used to extract nucleic acids at their relatively high concentration in the analyte. The main polymeric materials used include cellulose and its derivatives (nitrocellulose, cellulose acetate, mixed cellulose nitrate–acetate, diethylaminoethylcellulose, polyethyleneiminocellulose), agarose, dextran, polyestersulfone, polycarbonate, fluoroplasts, polyacrylates and polymethacrylates, polyaramids, polyamides, polyvinyl alcohol, polyaniline, polycaprolactone, polyacrylamide and polymethacrylamide, polystyrene. Chitosan, modified polycaprolactone, and magnetic particles coated with polydopamine, polyethyleneimine, polyvinylpyrrolidone, polystyrene, or polyamidoamine dendrimer are considered as promising polymers for further research in this field.

The article presents the results of processing funds stored in the herbarium of the Saratov State University (SARAT), belonging to the Iridaceae family. The Herbarium of SSU (SARAT) was founded in 1909; at present, significant material has been accumulated, which has not yet been fully processed. The Iridaceae family contains a number of species that are subject to protection, including at the federal level. It is quite large (more than 60 genera and 800 species distributed throughout the globe). According to the literature data on the territory of the south-east of Eastern Europe, where collections were carried out, stored in the herbarium of the Saratov State University named after N. G. Chernyshevsky (SARAT), two, possibly three genera are registered. According to the SSU herbarium (SARAT), 9 species belonging to 2 genera of the Iridaceae family were identified in the study area. As a result of the analysis, it turned out that 326 herbarium samples belonging to the studied family are stored in the SSU herbarium fund (SARAT). An analysis of the distribution of species was carried out according to two large summaries “Flora of the European part of the USSR”, and “Flora of the Lower Volga region” in accordance with the zoning adopted in them. As a result of the analysis of the collections of the SSU herbarium (SARAT) and the obtained field data, the range of the Iridaceae family was expanded, Iris arenaria, I. ruthenica, and I. sibirica are more widely distributed than previously thought. In addition, the question of the presence of I. ruthenica and I. tenuifolia in the studied region was considered based on our own field observations. There are no herbarium sheets for I. tenuifolia in the SSU herbarium (SARAT) confirming the presence of the species on the territory of the Saratov region. It is proposed to include I. ruthenica in the summary of the flora of the Saratov region and in the Red Book of the region, since this is the only locality of I. ruthenica in the region known to date.

Arylidenisoxazolones have been known since the second half of the 20th century and still retain their relevance as biologically active compounds and the basis for further transformations. Biological testing of synthetic heterocyclic compounds – 4-arylidene-3-methylisoxazol-5-ones, which differ in nature, position and number of substituents in the aryl fragment, was carried out: 4-(4-methoxybenzylidene)-3-methylisoxazol-5-one, 4- (4-chlorobenzylidene)-3-methylisoxazol-5-one, 4-(4-dimethylaminobenzylidene)-3-methylisoxazol-5-one, 4-(4-hydroxy-3-methoxybenzylidene)- 3-methylisoxazol-5-one, 4-(3,4-dimethoxybenzylidene)-3-methylisoxazol-5-one. The compounds were obtained at the Department of Organic and Bioorganic Chemistry of the Saratov National Research State University named after N.G. Chernyshevsky in order to identify the relationship between structure and biological action. The paper presents the characteristics of the tested compounds and a modified method for the synthesis of arylidenisoxazolones. Seedlings of spring soft wheat Triticum aestivum L. cv. Saratovskaya 36 served as test objects. To assess the physiological activity of the tested compounds, we used the seed germination index, analysis of the morphometric data of the seedling, the root-to-shoot ratio and the root index. The inhibitory effect of some compounds on seed germination has been established. The most pronounced effect was manifested during seed germination in a solution of 4-(4-hydroxy-3-methoxybenzylidene)-3-methylisoxazol-5-one at a concentration of 10-7M. No significant effect of isoxazolone derivatives on the growth of the first leaf of the test object was found. All tested 4-arylidene-3-methylisoxazol- 5-ones had a stimulating effect on the growth of the root system in length. The direct nature of the dependence of this effect on the concentration of a solution of 4-(4-chlorobenzylidene)-3-methylisoxazol-5-one and 4-(3,4-dimethoxybenzylidene)-3-methylisoxazol-5-one was determined. A positive effect of the tested compounds on the root-to-shoot ratio of seedlings was revealed (with the exception of 4-(4-dimethylaminobenzylidene)- 3-methylisoxazol-5-one). The root index of seedlings was determined and it was found that the presence of methoxyl groups has an inhibitory effect on the value of this indicator. Based on the data obtained, it can be concluded that 4-(4-dimethylaminobenzylidene)-3-methylisoxazol-5-one and 4-(4-chlorobenzylidene)-3-methylisoxazol-5-one are promising compounds for further research.
