Published: May 2023

Objetivo: Analisar as características da Síndrome de Sjögren (SS). Revisão bibliográfica: A síndrome de Sjögren é uma doença autoimune crônica do tecido conjuntivo, que envolve glândulas exócrinas e que pode ser dividida em primária e secundária. A tríade de sintomas clínicos inclui sintomas de secura, fadiga e dor. Como doença sistêmica, a SS pode envolver praticamente qualquer sistema orgânico, levando a manifestações clínicas extremamente pleomórficas. A taxa de incidência de SS é de 6,92 por 100.000 pessoas por ano. Em relação ao impacto da SS na qualidade de vida, a doença afeta negativamente a atividade diária do paciente devido à alta prevalência de fadiga, depressão, ansiedade e diminuição do desempenho físico. Considerações finais: A SS é uma doença autoimune cujo os principais sintomas são: ceratoconjuntivite seca e xerostomia. Além disso, pode ter múltiplos acometimentos a nível sistêmico. Não existe um único teste para o seu diagnóstico e esta deve ser suspeitada em pacientes com sintomas persistentes de secura, aumento da glândula parótida além de aumento inexplicável de cáries dentárias. O tratamento é feito com sintomáticos nos casos sem envolvimento sistêmico e naqueles afetados sistêmicamente são tratados com imunossupressão.

Authors: Mostofi Keyvan , Peyravi Morad
Published: May 2023

Introduction. Delayed wound healing is one reason for readmission after spine surgery. The main cause of delayed wound healing is infection. Infection rates after initial instrumented spine surgery reportedly range from 0.7% to 11.9%. However, there are noninfectious reasons for wound problems as well. Materials and Methods. This report presents 2 cases of noninfectious fistulization, 1 which occurred 11 months and 1 which occurred 2 years after surgery for implantation of a lumbar interlaminar device. Results. Although no sign of infection was found in either patient, in both cases it was necessary to remove the interlaminar device. Conclusions. These 2 cases of delayed noninfectious fistulization following instrumented spine surgery are the first seen by the authors of the current report, and as of the time of this writing, no such cases have been documented in the medical literature.

Published: May 2023

The high concentration of nitrogen (N) compounds in wastewater was found to be creating a reason of eutrophication, effect the biodiversity of aquatic ecosystems and human health. The aim of this study is to reduce harmful N forms from wastewater by biological nitrogen transforming (BNT) bacteria and to investigate the fluctuation of ammonium oxidizing bacteria (AOB), nitrite oxidizing bacteria (NOB), and pathogenic bacteria during this process, so compost representative. A sample of municipal wastewater was taken, and then subjected to the treatment process of BNT, which was subdivided into three stages of ammonification, nitrification, and denitrification. The result revealed that nitrifying bacteria were flocculated during biological nitrogen transformation, like AOB and NOB isolated until obtaining colonies during the nitrification process, by liquid mineral solution and Agar-Agar then calculated. The AOB count was 468 CFU/ml and NOB was 2130 CFU/ml in the sample. The existence of coliform bacteria, especially E. coli raises the possibility of water contamination by pathogens bacteria that cause many serious illnesses in human. Therefore, Mac-Conkey agar was used for the isolation of total coliform bacteria through the BNT process because it is selective and also differentiating agar that specialized in the growth of gram- negative bacteria. Total coliform bacteria decreased gradually, before ammonification (556 CFU/ml), after ammonification (226 CFU/ml), after nitrification (154 CFU/ml) and after denitrification (45 CFU/ml) that have been determined and indicated that further chemical disinfection like chlorination or ozonation were required for complete sterilization of pathogenic bacteria. The study concluded that all harmful forms of N and total coliform bacteria that cause human and ecosystem deleterious were reduced by BNT.

Published: May 2023

Crisis communication is an important element in the fight against the Covid-19 pandemic. It allows for efficient exchange of information between the government and society. The crisis situation caused by Sars-CoV-2 has a negative impact on human life and health as well as on the information environment. Institutions and specially appointed teams responsible for providing information are obliged to provide reliable information based on expert knowledge. A dangerous phenomenon is disinformation, which, combined with the pandemic, may cause an increase in the crisis situation and the risks associated with it. Crisis communication based on principles and goals will lead to overcoming the effect of panic, fear and ignorance among the public.
Modular Chemoenzymatic Synthesis of Ten Fusicoccane Diterpenoids
Authors: Jiang Yanlong , Renata Hans
Published: May 2023

Fusicoccane diterpenoids display intriguing biological activities, including the ability to act as molecular glue modulators of 14-3-3 protein–protein interaction. However, their innate structural complexity and diverse oxygenation patterns present enormous synthetic challenges. Here, a modular chemoenzymatic approach to this natural product family that combines de novo skeletal construction and late-stage hybrid C–H oxidations is presented. A convergent fragment coupling strategy allowed rapid access to a key tricyclic intermediate, which was subjected to chemical and enzymatic C–H oxidations to modularly prepare five oxidized family members. Complementarily, a biomimetic skeletal remodeling was conceived to render five rearranged fusicoccanes with unusual bridgehead double bonds synthetically accessible for the first time.

Published: May 2023

Glassy carbon (GC) materials demonstrate excellent thermal stability and mechanical response with low mass densities, which makes them excellent candidates for use in ablatives and carbon-carbon composites (C/C composites) used in aerospace and hypersonic vehicle structures. Although GC materials have been in development and use for decades, molecular simulation protocols need to be developed to accelerate the optimization of processing cycles and to drive the development of the next generation of C/C composites. The objective of this research is to establish reactive molecular dynamics (MD) simulation protocols to accurately predict the evolution of the molecular structure and properties of furan resin during polymerization and pyrolysis processes. The polymerization simulation protocols have been validated via comparison of the predicted density and Young’s modulus of furan resin with experimental values. The MD pyrolysis simulations protocols are validated by comparison of calculated density, Young’s modulus, carbon content, sp2 carbon content, the in-plane crystallite size (La), out-of-plane crystallite stacking height (Lc), and inter-planar crystallite spacing (d002) with experimental results from the literature for furan resin derived GC. Simulation parameters, such as temperature and pressure, are optimized within relatively short simulation times (2000 ps), and the predicted structures and mechanical properties are shown to agree with experimental measurements. The modeling methodology established in this work can provide guidance for the development of next-generation C/C composite precursor chemistries for thermal protection systems and other high-temperature applications.
How Ligands Interact with the Kinase Hinge
Authors: Zhao Zheng , Bourne Philip E.
Published: May 2023

ATP-competitive kinase inhibitors form hydrogen bond interactions with the kinase hinge region at the adenine binding site. Thus, it is crucial to explore hinge-ligand recognition as part of a rational drug design strategy. Here, harnessing known ligand-bound kinase structures and experimental assay resources, we first create a kinase structure-assay database (KSAD) containing 2915 nanomolar ligand-bound kinase complexes. Then, using the KSAD, we systematically investigate hinge-ligand binding patterns using interaction fingerprints, thereby delineating 15 different hydrogen-bond interaction modes. We believe these results will be valuable for de novo drug design and/or scaffold hopping of kinase-targeted drugs.
Revised Nitrogen Reduction Scaling Relations from Potential-Dependent Modeling of Chemical and Electrochemical Steps

Published: May 2023

The electrochemical nitrogen reduction reaction (NRR) is a promising route to enable carbon-free ammonia production. However, it is limited by the poor activity and selectivity of current catalysts. The rational design of superior NRR electrocatalysts requires a detailed mechanistic understanding of current material limitations to inform how these can be overcome. The current understanding of how scaling limits NRR on metal catalysts is predicated on a simplified reaction pathway that only considers proton-coupled electron transfer (PCET) steps. Here, we apply grand canonical density functional theory to investigate a more comprehensive NRR mechanism that includes both electrochemical and chemical steps on 23 metal surfaces in solvent under an applied potential. We applied Φmax, a grand canonical adaptation of the Gmax descriptor, to evaluate trends in catalyst activity. This approach produces a Φmax “volcano” diagram for NRR activity scaling on metals that qualitatively differs from the scaling relations identified when only PCET steps are considered. NH3* desorption was found to limit NRR activity for materials at the top of the volcano and truncates the volcano’s peak at increasingly reducing potentials. These revised scaling relations may inform the rational design of superior NRR electrocatalysts. This approach is transferable to study additional materials and reaction chemistries where both electrochemical and chemical steps are modeled under an applied potential.
Theoretical Insights into Dynamics of Gas-Phase Bimolecular Reactions with Submerged Barriers
Authors: Song Hongwei , Guo Hua
Published: May 2023

Much attention has been paid to dynamics of both activated gas-phase bimolecular reactions, which feature monotonically increasing integral cross sections and Arrhenius kinetics, and their barrierless capture counterparts, which manifest monotonically decreasing integral cross sections and negative temperature dependence of the rate coefficients. In this Perspective, we focus on dynamics of gas-phase bimolecular reactions with submerged barriers, which often involve radicals or ions and are prevalent in combustion, atmospheric chemistry, astrochemistry, and plasma chemistry. The temperature dependence of rate coefficients for such reactions is often non-Arrhenius and complex, and the corresponding dynamics may also be quite different from those with significant barriers or those completely dominated by capture. Recent experimental and theoretical studies of such reactions, particularly at relatively low temperatures or collision energies, have revealed interesting dynamical behaviors, which are discussed here. The new knowledge enriches our understanding of dynamics of these unusual reactions.

Objective.

To describe the variation in COVID-19 mortality among residents of Cali, Colombia, in the second wave of the pandemic, before vaccines, and in the fourth wave, with vaccination roll-out in process, taking into account variables of sex, age group, comorbidities, and interval between onset of symptoms and death, and to estimate the number of deaths averted by vaccination.

Methods.

A cross-sectional study of second wave and fourth wave deaths and vaccination coverage. The frequencies of attributes of deceased population in the two waves were compared, including comorbidities. Machado's method was used to calculate an estimate of the number of deaths averted in the fourth wave.

Results.

There were 1 133 deaths in the second wave and 754 deaths in the fourth wave. It was calculated that approximately 3 763 deaths were averted in the fourth wave in Cali in the context of vaccination roll-out.

Conclusions.

The decline in COVID-19-associated mortality observed supports the continuation of the vaccination program. Given the lack of data to explain other possible reasons for this decline, such as on the severity of novel viral variants, the limitations of the study are discussed.

Authors: Aguiar Joslaine Nunes , Carvalho Isis Polianna Silva Ferreira de , Domingues Raissa Allan Santos , Souto Maior Marta da Cunha Lobo , Luiza Vera Lucia , Barreto Jorge Otávio Maia , Tavares Noemia Urruth Leão
Published: May 2023

Objetivo.

Mapear políticas relacionadas à prevenção e ao controle da resistência aos antimicrobianos na perspectiva da saúde humana no Brasil e sistematizar a evolução histórica dessas políticas.

Método.

Desenvolveu-se uma revisão de escopo conforme as diretrizes do Instituto Joana Briggs e PRISMA. A busca na literatura foi realizada em dezembro de 2020 nas bases de dados LILACS, PubMed e EMBASE. Utilizaram-se os termos “antimicrobial resistance” AND “Brazil” e sinônimos. Uma pesquisa documental com os mesmos termos foi conduzida nos sites eletrônicos do governo brasileiro até dezembro de 2021. Foram incluídos estudos de todos os desenhos, sem restrição de idioma ou data. Excluíram-se documentos clínicos, revisões e estudos epidemiológicos que não referenciavam políticas de gestão da resistência aos antimicrobianos no Brasil. Para coleta e análise de dados, estabeleceram-se categorias baseadas em documentos da Organização Mundial da Saúde.

Resultados.

Desde antes da criação do Sistema Único de Saúde, o Brasil possuía políticas relacionadas à resistência aos antimicrobianos, como o Programa Nacional de Imunização e programas de controle de infecção hospitalar. No final das décadas de 1990 e 2000, estabeleceram-se as primeiras políticas específicas sobre resistência aos antimicrobianos (redes e programas de vigilância) e estratégias de educação. Destaca-se o Plano de Ação Nacional de Prevenção e Controle da Resistência aos Antimicrobianos no Âmbito da Saúde Única (PAN-BR), de 2018.

Conclusões.

Apesar do longo histórico de políticas relacionadas à resistência aos antimicrobianos no Brasil, foram identificadas lacunas, sobretudo no monitoramento da utilização de antimicrobianos e na vigilância da resistência aos antimicrobianos. O PAN-BR, primeiro documento de governo elaborado na perspectiva One Health, é um marco nas políticas brasileiras.

The COVID-19 pandemic has yet to find a comprehensive solution. Therefore, all employment sectors, whether public or private, have significantly changed their work environment since the Movement Control Order (MCO) implementation on March 18, 2020. Thus, most organizations began to adopt alternative communication methods to carry out routine tasks with social distancing, and no longer necessary to have a face-to-face meetings. All discussions and meetings have taken place online with the employee. Since many employees Work from Home (WFH), WhatsApp groups have become a viable option for discussing work matters during the pandemic. Besides, Malaysia's public service faces a challenge in adapting to this new normal of using digital technologies as a part of communication. Thus, the study focuses on the Perak State of Public Work Department. The qualitative study will using semi-structured interview questions among Perak State of Public Work Department employees. Ten (10) informants will be selected for this study. The sampling technique is non-probability sampling. The qualitative method is chosen due to the appropriateness of the study matter as it adds depth, details, and meaning. This study employs a Social Presence Theory and Media Richness Theory. Researchers need to understand its relation to social media usage in the organisation. Implications for conducting this study will provide findings to researchers to see the use of WhatsApp groups among employees in the Public Work Department. After that, the researcher can identify weaknesses, challenges, and problems arising from WhatsApp usage during the pandemic. The findings will be able to facilitate the Public Work Department to improve a more effective medium for communication between the organization, employees, and customers.

In conjunction with the introduction of the movement control order (MCO) to help stop the spreading of the COVID-19 virus, academic establishments around the country have taken significant initiatives to make sure that their students could continue to learn through online mediums. Thus, students and educators must begin preparing their minds for alternative classroom instructions that do not involve face-to-face interactions. This shift has sparked anxieties about how school children and tertiary level students from various social and economic backgrounds will adapt to this new digital classroom setting. With the objectives to identify the challenges faced by UiTM students in adapting to the ODL mode at home and to examine the challenges faced by the students staying in three different localities; urban, sub-urban and rural, 1,931 students from all UiTM campuses answered a self-constructed online questionnaire. A descriptive analysis and analysis of variance (ANOVA) was conducted using IBM-SPSS version 24 software to analyse the data. The findings revealed that while most of the students did not face significant problems on the infrastructure aspect, students from rural and sub-urban areas faced problems following the scheduled timetable provided by the university for online learning. Personal factors of family commitment, health, and other personal issues were found to affect their ODL session most. Since UiTM students’ come from all over the country and from various family backgrounds, it is expected that the findings would enable the university administrators to better understand the challenges faced by the students, thus implementing effective and efficient learning environment that suits and supports the diversity of the students should there be a need for an ODL mode in similar outbreaks in the future

During the COVID-19 epidemic, social media was the main way for people to communicate with others. While social media brings convenience to all people, it also has its dark side. This study examined the link between the psychological characteristics of the general public at the time of blockade and compulsive social media behavior based on the I-PACE theory and compensatory internet use theory. During the first outbreak of COVID-19, 416 participants between the ages of 18 and 40 in China were recruited using an online survey in social media platform for this research. Findings highlight that users who feel high loneliness may tend to use social media compulsively. Results also indicated that social interaction anxiety and FoMO serially mediate the link between lockdown loneliness and compulsive use. This research demonstrated that higher social presence could increase lonely users’ tendency of compulsive use. Higher social presence can improve the risk of compulsive social media usage when individuals in FoMO state. During the COVID-19 pandemic, individual in higher boredom proneness may positively affect the association between lockdown loneliness and compulsive use. The results can provide a potential way to understand compulsive social media usage and prevent individuals’ negative emotions from contributing to unhealthy social media usage. The results of this study provide a range of references for social media users, social media platform providers, and governments to use social media effectively and sustainably during the global COVID-19 pandemic and post-pandemic period.

THERAPEUTIC POTENCY OF ESTROPHANTHIN IN PSEUDO-PREGNANCY (HYDROMETRA) OF GOATS
Authors:   Timirâzevskaâ selʹskohozâjstvennaâ akademiâ, SHATSKY K.O.
Published: May 2023

The aim of the study was to carry out a comparative evaluation of the therapeutic potency of Estrophantine®, a drug of the highly active synthetic analog of prostaglandin F2 alpha (PgF2α) cloprostenol, when goats with hydrometer were twice injected intramuscularly with a 10-day interval in a dose of 0.5 and 1.0 ml, respectively. The objects of the study were breeding goats of breeding age (n=6) and lactating goats (n=37) of the Zaanen breed diagnosed with false pregnancy during screening ultrasound examination. The animals were divided into two experimental groups according to the analogy principle. The animals in the first experimental group (n=21) were twice injected intramuscularly with a 10-day interval in the dose of 0.5 ml (125 μg cloprostenol), and those in the second group (n=22) were also twice injected intramuscularly with with a 10-day interval, but in the dose of 1.0 ml (250 μg cloprostenol). The results of the study showed high therapeutic potency of Estrophantine® when goats with hydrometer were twice injected intramuscularly with with a 10-day interval in the dose of 1.0 ml. After the first dose of the preparation complete expulsion of intrauterine fluid was noted in 81.82% of goats with hydrometer. The effectiveness of the method for a complete course of treatment was 100% according to the percentage of cured animals, and 86.36% and 77.27% according to the frequency of renewal of sexual cycling and pregnancy rate, respectively. None of the 5 (22.73%) goats found to be infertile registered a re-lapse of hydrometra after treatment. An Estrofantin® dose of 0.5 ml (125 μg cloprostenol) was found to be inadequate for treat-ment of goats with hydrometra. After the first dose, complete expulsion of intrauterine fluid was noted in only 52.38% of animals. When Estrophantine® is used at the lowest therapeutic dose (125 μg cloprostenol) the effectiveness of prostaglandin therapy over a full course of treatment is reduced by 4.76% in the proportion of cured animals, by 10.17% in the renewal of sexual cycling and by 15.37% in pregnancy rate. At the same time, the risk of relapse is 5%.
REDUCING NITROGEN NUTRITION OF PLANTS TO WITHSTAND THE GREENHOUSE EFFECT: ASSESSING THE IMPACT ON AGRICULTURE
Authors:   Timirâzevskaâ selʹskohozâjstvennaâ akademiâ, SVETLOV N.M.
Published: May 2023

One way of reducing the anthropogenic impact on the climate is to limit the introduction of nitrogen into the soil with mineral fertilizers. This will reduce the release of volatile nitrogen compounds into the atmosphere, which have a strong greenhouse effect. A scenario analysis using the VIAPI model (an economic-mathematical model of a partial equilibrium of the wholesale agricultural markets of the constituent entities of the Russian Federation), is used to assess the changes in these markets and in the country’s agriculture as a whole in the case of reduced introduction of nitrogen into the soil with mineral fertilizers. Scenarios were investigated for a 10% reduction in national application at actual fertilizer efficiency levels and a 50% increase in efficiency to the level of best regional practices. It is shown that, in general, agriculture is able to adapt to these scenarios, reducing the gross agricultural production by only 2.09% or 2.85%, respective-ly to the baseline scenario (which does not include nitrogen application restrictions). Adaptation takes place due to changing the sectoral structure in favor of open ground vegetable production and meet cattle breeding, changing territorial structure in favor of the regions of the corresponding specialization. The decrease in nitrogen application is achieved by relatively few federal subjects, while in the rest it remains the same. If the reduction in the introduction of nitrogen into the soil with mineral fertilizers is accompanied by the efficiency growth, there is an opportunity to avoid any damage to agricultural production, both sectorally and territorially. This opportunity is conditioned by investments and, possibly, state support, the feasibility of which is to be studied within the framework of the project approach.

Therefore, the search for models of in vivo assessment of the level of zinc in the muscle tissue of animals is relevant. The level of zinc in muscle tissue influences the quality indicators of beef. The samples of the diaphragmatic muscle weighing 100 g were taken from Hereford cattle bred under typical conditions of an agribusiness sector in the south of Western Siberia (Russia). Elemental analysis was carried out by the atomic absorption method with electrothermal atomization on a spectrometer MGA-1000. Measuring of hematological parameters – erythrocyte, leucocyte and haemoglobin levels – was carried out on an automatic hematological analyzer PCE-90VET. Biochemical parameters were determined using photometric methods on a Photometer-5010 biochemical analyzer. The coefficients of regression models were calculated using the least squares method. The choice of the most accurate and effective model was made on the basis of a comprehensive assessment of indicators of internal and external quality criteria. The values of the dependent variable correspond to the Gaussian one. A high correlation between independent variables was revealed. The selection based on internal and external quality criteria revealed an optimal model for predicting the level of zinc in muscle tissue of Hereford cattle, containing three predictors: erythrocyte sedimentation rate (mm/h), color index and total cholesterol (mmol/l). The model meets the necessary assumptions: the residuals are normally distributed, there are no autocorrelations, and the observations are influential. There is no evidence of multicolleniality between the main effects of the main model (VIF = 1.0–1.1). The resulting model can be used for in vivo assessment of the level of zinc in the muscle tissue of cattle.

The results of the studies of changes in biological and enzymatic activity of soils depending on the anthropogenic influence and the size of soil aggregates are presented. The work was carried out in 2015-2021 in the conditions of the south-east of the Central Chernozem region. The soil of the experimental site is ordinary (segregational) medium–sized medium-humus heavy loamy chernozem. The objects of research are long–used arable land and the layland used for haying since 1882. The quantitative change of individual groups of microorganisms, determined by the nature of the impact on the soil cover, is shown. The total number of microorganisms in both arable land and chernozems under natural vegetation was at the same level of 40.0 and 39.3 million CFU, respectively. Significant differences in the biological activity of chernozems by individual groups of microbial cenosis structure were noted. An increase in the number of ammonification bacteria on the arable analogue was revealed by an average of 30.7%; micromycetes by 4.4%; cellulolytics by 46.4%; nitrifiers by 46.9%; calculated humification coefficient by 45.4%. According to other components of microbial cenosis, the advantage of layland steppe soils is noted: actinomycetes by 18.5%; humus mineralizers by 11.8%. An increase in the activity of most groups of microorganisms was shown in the smaller structural units of 1-5 mm. In larger mesoaggregates, CFU numbers tend to decrease. This pattern is most clearly traced in agrogenically altered soils. In the soils occupied by natural vegetation, there is a higher activity of biochemical processes.

Mitochondrial DNA polymorphism, which is one of the most common genetic markers, is actively used in the study of various animal species. Since the mitochondrial genome has evolved over many years within a species, this has influenced the fixation of mutations and the formation of mitochondrial lineages that share a common origin and form mitochondrial genomes, called mtDNA haplogroups. The objectives of the work were to evaluate the genetic diversity of pigs of two maternal breeds of domestic reproduction based on the analysis of mtDNA D-loop polymorphism and to compare the results obtained with identical sequences from the NCBI database by breed and their geographic distribution. 39 Landrace pigs and 49 Large White pigs were used for the study. MtDNA was isolated from tissue samples (ear notch). The number of haplotypes, haplotypic and nucleotide diversity, and the average number of nucleotide substitutions per site were determined to assess the genetic diversity. 23 polymorphic sites were found: 21 in Landrace pigs, 17 in Large White pigs. A total of ten haplotypes were identified in the study population. The NCBI database found 75 identical sequences for pigs of different breeds bred around the world. After determining the nucleotide sequences of the D-loop fragment of the mtDNA of Landrace and Large White pigs of domestic reproduction and comparing them with the sequences from the NCBI database, the presence of identical sequences in the animals we studied and in the representatives of European and Asian breeds, including commercial and local was established. The materials obtained show that the assessment of mtDNA polymorphism contributes to the identification of phylogenetic relationships between populations, tracing of pedigree processes, and can be considered as an additional criterion of selection and breeding work.

The eff of herbicides (Bison, Stratos Ultra) and the preparations of natural origin (Bio-Fish, BioAlgo) on the yield formation, sowing qualities and initial growth of the mid-ripening soybean variety Zhuravushka selected by the Federal Scientifi Center "All-Russian Scientifi Research Institute of Soybean" was studied. The studies were conducted in 2020 and 2021 in the experimental fi of the All-Russian Scientifi Research Institute of Soybean located in the southern part of the Amur Region (Sadovoye village, Tambovsky District). It was found that an average of two years of application of the preparations of natural origin Bio-Fish and Bio-Algo for pre-sowing treatment of seeds and vegetative plants increased the safety of the plants to the harvest period and crop yield, as well as improved the seed quality. The greatest preservation to harvesting was observed when the seeds were treated before sowing with Bio-Fish and the vegetative plants with herbicides (93.9%, which is 6.4% more than in the control variant and 7.8% more than in the variant where only herbicide treatment was used). Analysis of the yield structure showed that, on average over the years of research, pre-treatment of seeds with Bio-Fish and the vegetative plants with herbicides Bison, Stratos Ultra increased the number of beans to 5.8 pieces, and the seeds to 12.9 pieces per plant compared to the control variant. Seed weight per plant increased to 2.47 g relative to the control. The use of biological preparations increased the biological yield regardless of the treatment variant by 0.64 t/ha compared to the control and by 0.66 t/ha compared to the herbicide treatment.

Background: One of the government's strategies to support women's equal rights is to issue a policy in which people of reproductive age, both men and women, are expected to participate in the Family Planning program as an effort to raise awareness, willingness and ability of the community to improve their welfare independently. This study aims to analyze the influence of attitude, partner support, and level of education on men's participation in the use of contraception. Subjects and Method: This was a systematic review and meta-analysis. The study population was men of reproductive age. Intervention= positive attitude, strong partner support, and high education. Comparison= negative attitude, weak support, and low education. Outcome= the use of contraceptives. Data search was carried out syste¬ma¬tically using electronic databases from Pub¬med, Google Scholar, Europe PMC, Science Direct and Springer Link. Keywords used “Attitude” AND “Partner support” OR “Discuss with partner” AND “Educational status” OR “Educational level” AND “Men parti¬ci¬pa¬tion” OR “Men Involvement” AND “Contraception” OR “Family Plann¬ing” OR “Vasec-tomy” OR “Con¬dom”. The selection of primary articles used the PRISMA flowchart which was analyzed using Review Manager 5.3. Results: Six studies showed that men with a positive attitude were 3.69 times more likely to use contraception than men with a negative attitude (aOR= 3.69; 95% CI= 2.23 to 6.09; p<0.001). Six studies showed that men with strong partner support are 2.48 times more likely to use contraception than men with weak partner support (aOR= 2.48; 95% CI= 2.04 to 3.02; p<0.001). Eight studies showed that men with a high level of education increased the likelihood of male contra¬ceptive use (aOR= 2.07; CI 95%= 1.45 to 2.96). Conclusion: Positive attitude, strong partner support, and a high education increase the use of male contraceptives. Keywords: attitude, partner support, level of education, contraception.

In this paper, the concepts of hybrid pure hyperideals in ordered hypersemigroups are introduced and some algebraic properties of hybrid pure hyperideals are studied. We characterize weakly regular ordered hypersemigroups in terms of hybrid pure hyperideals. Finally, we introduce the concepts of hybrid weakly pure hyperideals and prove that the hybrid hyperideals are hybrid weakly pure hyperideals if such hybrid hyperideals satisfy the idempotent property.

The article considers trends in the transformation of the labor market under the influence of a change in the paradigm of personnel management and analyzes new forms of interaction between employer and employee, in particular remote work. It analyzes the statistics illustrating the prospects for the development of the remote form of employment and formulate the dependence between the spread of remote work and such parameters as the size of the settlement, the industry, the size of the organization, the level of GDP per capita. The characteristics of such form of employment and the requirements for employees are specified and the classification of remote workers is given. There is an analysis in advantages of that form of employment from the point of view of employees and employers. The most significant ones are identified. In addition, the risks of using remote workers from the point of view of ensuring the information security of the organization are assessed. The authors highlight typical mistakes of employees associated with non-compliance with security principles and the associated risks of violating the integrity of the organization’s information system. They also propose directions in developing the functions of personnel management services in the organization related to the transformation of traditional management tools, and highlight measures aimed at reducing information security risks. A conclusion is made about the need to develop personnel management systems in accordance with the principles of the information economy.
