Urgency of the research. The rapid development of IT technologies and intensive informatization of all spheres of society leads to the emergence of new information threats, so information security is one of the most important tasks of the IT industry. An important element in the development of new methods of information protection is the search for vulnerabilities in information systems. Target setting A promising area in the field of information security is the development of active methods of providing protection, among which we can highlight the search for vulnerabilities of information systems. Actual scientific researches and issues analysis. Ethical hacking and penetration testing play a significant role in modern information security research, leaving in the shadows such an effective tool as volunteer research into the vulnerabilities of public information resources. Uninvestigated parts of general matters defining. Currently, in the works of domestic and foreign scientists, insufficient attention is paid to the opportunities for volunteers to study the vulnerabilities of state information resources. The research objective. The purpose of the article is to highlight the differences between approaches to cybersecurity in business structures and government agencies of Ukraine. The statement of basic materials. Customers are providing more and more personal information to IT companies, and companies need to protect it. But virtually every program has vulnerabilities, so personal customer data can end up in the hands of criminals. Conclusions. An indicator of the work of cyberpolice is the detection of crimes. Yes, cyberpolice does a lot of good, such as catching fraudsters and distributors of child porn. However, specific computer crimes have been uncovered. That is, the level of protection by the state of both its own resources and citizens from criminal encroachments is still low.

Published: August 2021

Despite advances in pharma and high-technology medicine, the rate of burdensome hospital admissions and mortality in patients with chronic heart failure (CHF) remains high. Over half of all admission-entailing decompensations have been repeatedly shown to emerge from non-compliance with outpatient prescriptions. Poor adherence to medication and non-medication treatment can only be broken by improving the patient’s awareness of the disease and his closer monitoring by healthcare professionals. The power of clinical and laboratory illness monitoring in line with the recommended quality criteria of medical aid in heart failure (HF) is strongly limited today by time resources available in outpatient and midwifery clinics. Meanwhile, an international and certain domestic experience has been built up to run CHF outpatient centres with involvement of specially-trained nursing and senior medical staff. Analytic evidence on such centres suggests a reduction in mortality and hospitalisation rate among the visiting patients. To combat existing drawbacks of CHF outpatient care, the National Medical Research Center of Cardiology in alliance with the Specialist Society of Heart Failure have developed the nurses’ guidelines for CHF rooms and are launching a medical staff training programme to manage CHF rooms, registry and data analysis. Furthermore, a procedure has been developed for patient routing to regional CHF outpatient cabinets that is being actively deployed in the Tyumen Region.

Authors: Antonov V. N. , Osikov M. V. , Ignatova G. L. , Zotov S. О.
Published: August 2021

Background. The coronavirus disease 2019 (COVID-19) caused by the SARS-CoV-2 virus has swept across countries worldwide. Despite an unprecedented volume of research, few drug therapies have been proved effective. The lack of evidence-based strategies entailed many practical treatments. Hypercoagulability observed in COVID-19 patients has sparked a debate in the medical community on therapeutic value of anticoagulants.Objectives. A review of up-to-date evidence supporting the therapeutic effect of unfractionated and low molecular-weight heparin as anticoagulant in treatment for COVID-19. Methods. Russian-language and foreign literature was mined in the RSCI, Scopus, PubMed, medRxiv and eLibrary databases for the years 2020–2021, with considering selected impactive publications within 1991–2019 as well. The query keywords were COVID-19, heparin [гепарин], hemostasis [гемостаз], thromboembolism [тромбоэмболия]. Peer-reviewed scientific journals received priority. Content and descriptive analytics were used as research tools.Results. The review surveyed 84 literature sources, with 51 articles selected for downstream analysis. We highlight usage of heparin and its fractions in treatment for COVID-19 and preclinical evidence verifying the antiviral and anti-inflammatory properties of heparin and synthetic heparin-like drugs in COVID-19. The known and plausible side effects demanding additional prospective randomised controlled trials on anticoagulant application in COVID-19 are reviewed, with an assessment of oral direct-acting anticoagulant drug efficiency.Conclusion. Drug-based therapies for haemostasis correction in COVID-19 are currently limited. The paucity of evidence warrants heparin usage as a safer therapy in acute COVID-19 compared to oral anticoagulants. However, the balance of its potential benefits vs. risks must be observed. The benefits and risk uncertainty in heparin treatment require randomised clinical trials and further studies to evaluate safety of direct-acting oral anticoagulants after the patient’s discharge in COVID-19.

This study aimed to isolate indigenous Antagonistic Bacteria (AB) against common soil-borne phytopathogens, including Rhizoctonia solani, Phythium sp., Fusarium oxysporum. Biosynthesis of Indole-3-Acetic Acid (IAA), generation of Hydrogen Cyanide (HCN), and siderophores production were assessed for their involvement in the antagonistic activities. Rhizospheric soil of bean roots, sunflowers, wheat, rice, and humic and semi flooded soils were used to isolate twenty-one bacterial strains for phytopathogenic antagonism. It was found that nine isolates have potential antagonistic activity against three common soilborne pathogens. Antifungal productivity for IAA, HCN, and siderophores was screened on the isolates while nine ABs were identified. To choose statistically significant isolate for the formulation, the principal component analysis was performed with five variables (IAA production, siderophores production index, antagonistic activities against three phytopathogens). Among the nine isolates, the isolate Pseudomonas alicaligenes shew a positive correlation with all variables. In particular, the strain demonstrated to be an antagonistic strain against the fungal pathogens and a strong producer of siderophores, HCN and IAA, We prepared the biocontrol agents with rice flour, glutinous rice flour, Monosodium Glutamate and Chitosan that were found to maintain the up to three months for convenience of field applications.

Hepatitis E virus (HEV) infection, usually self-limiting in immunocompetent individuals, may adopt a chronic course in immunodeficient patients. A low threshold for HEV screening in immunodeficient patients is advocated so early management can be initiated to minimise liver injury. This retrospective, observational study evaluated all cases (n=11) of chronic HEV diagnosed in immunodeficient patients in 2 university hospitals in Bristol, UK between February 2014 and October 2017. We report our experiences in the management of chronic HEV including ribavirin use. No patients achieved viral clearance spontaneously or with reduction of immunosuppression and so all were treated with ribavirin. The median time between chronic HEV diagnosis and initiation of ribavirin was 91 days (range, 1–293 days). The median ribavirin dose at initiation was 1000 mg/day (range 800-1200 mg/day) and at cessation was 900 mg/day (range 600–1200 mg/day), reduced due to anaemia. Different end points guided treatment cessation including negative HEV RNA PCR serology +/- negative stool HEV RNA PCR +/- biochemical remission at various time points. Following ribavirin therapy, HEV relapse occurred in 1 patient. The mean duration of ribavirin therapy, excluding the patient who was re-treated, was 4.6 months. One significant adverse event of severe anaemia requiring transfusion was observed. This case series supports the use of ribavirin monotherapy for chronic HEV in immunodeficient patients. Anaemia commonly developed prompting ribavirin dose reduction. We advocate 2 consecutive negative serum and stool HEV RNA PCR results sampled at 4 weekly intervals to guide ribavirin cessation.

Published: August 2021

This overview demonstrates the need for school librarians to consider supplementing coding instruction with ethical discussions. School librarians are increasingly incorporating coding into library instruction through play, tutorials, collaboration in content areas, and design thinking projects. To enhance students’ ethical decision making and empathy for others, school librarians can also incorporate ethical decision-making into coding activities. In this article, the authors explain why this is important, and present an ethical discussion model. These strategies may help school librarians work towards teaching social justice issues as part of coding programming.

В статті представлено результати наукових досліджень щодо визначення можливості сумісного розміщення розкривних порід кар’єру і відходів збагачення залізної руди в одному відвалі. Розглянуто два варіанти сумісного розміщення відходів збагачення в сухому стані з породами розкриву, а саме, складування відходів збагачення бульдозерним відвалоутворенням та складування відходів збагачення у воронки. Виконано геомеханічне моделювання поведінки відвалу із суміщеним розміщенням відходів для запропонованих варіантів за допомогою програмного продукту Plaxis 3D. Для кожного з двох варіантів сумісного розміщення відходів збагачення в сухому стані зі скельними породами розкриву кар’єру були побудовані геомеханічні моделі поведінки відвалу в процесі його формування та на кінець будівництва. Визначено максимальні деформації, що утворюються під час його будівництва за умови поярусного формування, та коефіцієнт запасу стійкості відвалу за умови його поярусного відсипання. Представлені графічно закономірності розвитку деформаційних процесів у відвалі по мірі формування кожного ярусу при сумісному складуванні порід розкриву та відходів збагачення.На основі проведених геомеханічних розрахунків отримано можливі об’єми розміщення шламу у розкривному відвалі і встановлено, що при бульдозерному відвалоутворенні за умови сегрегації і втирання зневоднених відходів збагачення в укоси відвалу, можливо досягти підвищення місткості відвалу на 8,7 % без зміни його геометричних розмірів. За умови складування зневоднених відходів від збагачення у воронки встановлено, що їх вміст у загальному об’ємі відвалу в середньому може становити 21,9 %. Отримані результати досліджень дають можливість продовжити наукові дослідження з вивчення та прогнозування геомеханічних параметрів відвалів при сумісному складуванні розкривних порід та зневоднених відходів інших корисних копалин, а також встановлення оптимальних варіантів складування в різних технологічних і гірничо-геологічних умовах.

Low-cost, reliable and quick screening diagnosis of coronavirus can be implemented on the basis of intelligent technologies for analyzing a set of signs and symptoms with solving the problem of pattern recognition in the basis of artificial neural networks. The high degree of coronavirus infection diagnostic procedure uncertainty, the vector dimension of input factor-symptoms, fuzzy conditioning and poor formalizability of the subject condition connection with these symptoms require appropriate analytical tools. An analysis of the problem and possible solutions allows justifying the feasibilit y of implementing screening diagnostics as a solution to the problem of nonlinear optimization in a multidimensional space of high-dimensional factors and states. Artificial neural networks with compulsory training on a representative sample were chosen as a tool for implementing the project. The proposed technology brings diagnostics of coronavirus infection closer to full automation, robotization and intellectualization of complex monitoring (diagnostic) systems as the most promising technology for pattern recognition in systems with a high degree of entropy and allows you to solve the problem at the lowest cost and required performance indicators.

The complex value of imbalance of load server entered, which taking into ac-count the weight coefficients for processor, memory, and network bandwidth. These weight coefficients allow to select the importance of each network resource (CPU, memory and bandwidth) compared with each other. Also, this method allows to calculate the imbalance of the system servers. Using the method in load balancing allows to distribute requests by servers such way that deviation of the load servers from the average value was minimal, that allow to provide higher system performance parameters (utilization efficiency) and faster processing flows. Conclusions. The work proposed a solution to the actual scientific problem of assessing the load of nodes of a distributed system. The proposed method is based on calculating the processor load, memory load, and channel bandwidth by flows of different service classes. Also introduced a complex value of server load imbalance, taking into account weights for processor, memory and network bandwidth. Accordingly, this method allows you to calculate the imbalance of all servers in the system, the average operating time for various balancing algorithms and the efficiency of using the system resources.

Background: Hepatitis B virus (HBV) infection is a major health problem causing considerable morbidity and mortality from both acute infection and chronic sequels including chronic hepatitis, cirrhosis and hepatocellular cancer. Aim: To estimate the prevalence of hepatitis B virus infection and the associated factors among children and adolescent in the traditional schools, East Nile locality. Methods: Descriptive cross-sectional school-based study. Sero-prevalence survey was conducted among school children and adolescent aged 2–19 years. Total sample of 880 students were tested for Hepatitis B surface antigen (HBsAg) in serum using immune-chromatographic assay. Data were analyzed using IBM statistical package for social sciences version 20 with statistical significance of (p<0.05). Results: A total of 4.2% tested positive for HBsAg, (3.2%) among children and (4.3%) among adolescent, this is lower than the reported prevalence in the country. There was no significant association between the pre-determined risk factors and hepatitis B virus infection in the study group. Conclusion: The prevalence of HBV infections in this study was lower than the overall prevalence in Sudan. Further studies are needed to evaluate the risk factors for hepatitis B virus infection among children and adolescents in Sudan. Hepatitis B virus vaccine should be implemented in the vaccination program for children, in addition to awareness campaigns about the virus and transmission methods.

Published: August 2021

This paper analyses the intergenerational transmission of formal-informal employment. Using the data from the Household Integrated, Income and Consumption Survey (2015-16) and applying Probit and Multinomial Logit Model, it was manifested that intergenerational persistence is higher in informal employment. The transmission of informal employment from the father to the son is higher in rural regions as compared to the urban regions. Further, scrutinizing informal employment in different occupations revealed its higher persistence in elementary occupations. In the older cohort, the likelihood of the transfer of informal employment as compared to the younger cohort was found to be higher. Father’s occupation remains the primary determinant of the sons’ entry into the labor market. There are limited chances for the sons whose fathers are in low status occupations to move to high status occupations as compared to those sons whose fathers are already employed in high status occupations.

The world is undergoing a dramatic COVID-19 induced transformation in almost every sector of the economy including education. The virus has drastically changed the dynamics of teaching and learning across the globe. This paper is an attempt to examine how COVID-19 has affected the higher education sector of Pakistan. An empirical analysis of the online teaching experience of both the public and private sector university faculty was conducted for this purpose. The current study aims to highlight the need for developing tools for effective teaching that have wide ranging applications in Pakistan, an exercise that requires concerted research effort. Education sector is among the worst hit sectors due to the spread of the coronavirus in Pakistan. Indeed, educational indicators for Pakistan and the current state of the education sector indicate a gloomy scenario. Instructors and students across universities, colleges and schools were ill-prepared for a situation where they had to rely on online teaching and other web-based instructional tools. In this scenario, certain areas in the education sector require extensive research, training and application, such as digital education, assessment tools and applications, project-based learning (PBL), and mobile based strategies for developing self-regulated learners (SLRs) as well as the introduction of various other tools meant to enhance student engagement during the process of learning. The study found that the faculty in the public and private sector universities was not inclined towards online teaching. The results also revealed that the private sector institutions were more facilitating than the public sector institutes. However, the role of HEC during the pandemic was proactive. There is a need to take effective measures at the local and national level to facilitate the student body as well as the instructors lest there is a severe decline in educational indicators or rise in the dropout rate.

Published: August 2021

Bu araştırmanın amacı; yoğun rekabet ortamında faaliyet gösteren hizmet işletmesi çalışanlarının müşterilere yönelik tutum ve davranışlarını incelemek, müşterilerin bu tutum ve davranışlar içerisindeki tükenmişlik algısını tespit etmek, bu algıların müşteri sadakatine etkisi olup olmadığını saptamaktır. Bu doğrultuda rekabetçi bir işletmenin 145 müşterisinden yüz yüze anket yöntemiyle veri elde edilmiş ve bu veriler istatistiksel olarak analiz edilmiştir. Gerçekleştirilen analizler sonucunda; algılanan tükenmişlik ile müşteri sadakati arasında ise negatif yönde anlamlı bir ilişki saptanmıştır. Regresyon analizi sonucunda; müşterilerin hizmet sunan personele yönelik 1 birimlik tükenmişlik algısının müşteri sadakati üzerinde 0.320 birimlik bir azalışa neden olduğu saptanmıştır. Bununla birlikte müşteri sadakatinin hizmet satın alınan süreye göre ve hizmet satın alma sıklığına göre anlamlı bir farklılık göstermediği ancak cinsiyete göre anlamlı bir farklılık gösterdiği ve kadın müşterilerde müşteri sadakatinin daha yüksek olduğu belirlenmiştir. Algılanan tükenmişlik düzeyinin ise hizmet satın alınan süreye göre anlamlı bir farklılık göstermediği anlaşılmıştır.
