Authors: Tyshchenko Vitalii
Published: September 2023

This article analyses various training methods and neural network tools for fake news detection. Approaches to fake news detection based on textual, visual and mixed data are considered, as well as the use of different types of neural networks, such as recurrent neural networks, convolutional neural networks, deep neural networks, generative adversarial networks and others. Also considered are supervised and unsupervised learning methods such as autoencoding neural networks and deep variational autoencoding neural networks.

Based on the analysed studies, attention is drawn to the problems associated with limitations in the volume and quality of data, as well as the lack of efficiency of tools for detecting complex types of fakes. The author analyses neural network-based applications and tools and draws conclusions about their effectiveness and suitability for different types of data and fake detection tasks.

The study found that machine and deep learning models, as well as adversarial learning methods and special tools for detecting fake media, are effective in detecting fakes. However, the effectiveness and accuracy of these methods and tools can be affected by factors such as data quality, methods used for training and evaluation, and the complexity of the fake media being detected. Based on the analysis of training methods and neural network characteristics, the advantages and disadvantages of fake news detection are identified. Ongoing research and development in this area is crucial to improve the accuracy and reliability of these methods and tools for fake news detection.

Authors: Kukharska Nataliia , Lagun Andrii
Published: September 2023

The cyber threat landscape has undergone major changes in recent years. Compared to any period since the beginning of the information age, it is more diverse and broad. First, the Covid-19 pandemic, namely the resulting transition of organizations to remote work and then the full-scale invasion of Ukraine by the Russian Federation, made adjustments to the information security strategy. Today, most organizations are aware of security threats and the need to create a reliable information security management system to ensure their effective operation in an information environment that is aggressive both technically and socially. An important area of information security in an organization is human resource management since, according to statistics from a number of reputable analytical centers, employees are the weakest link in any data security system. The organization's human resources management includes a thorough recruitment process, fostering a responsible attitude to work in compliance with the requirements for protecting restricted information, developing a corporate culture of information security and dismissal procedures.

The article provides a list of documents of the regulatory framework, namely, international security standards, regulatory documents of public authorities, and internal documents of an organization regulating the rules and methods of work with personnel. The main motives for the unlawful behavior of an internal attacker are highlighted, and the organizational measures recommended in the context of ensuring information security at all three stages of interaction between a person and an organization: employment, employment, and dismissal are described. There is also indicated the expediency of using psychoanalysis, psychology, management ethics and conflictology methods in the field of personnel management for forecasting and prevention of informational threats.

Authors: Subach Ihor , Kubrak Volodymyr
Published: September 2023

The article presents a model for identifying cyber incidents by a SIEM system that occur in the course of operation of information and communication systems (ICS). A list of tasks performed by the SIEM system in the ICS protection circuit and the mechanisms that form its basis, which, in turn, are components of the general process of correlation of events occurring in the ICS, is given. The methods of the correlation process aimed at removing, combining and linking data on events in the ICS with the establishment of its causality and priority are analyzed. It is concluded that the existing methods are ineffective in the context of incomplete and inaccurate information about cyber incidents. The tuple model for recognizing cyber incidents is analyzed and an improved model based on the theory of fuzzy sets and linguistic terms is proposed to eliminate its shortcomings. A new formulation of the problem of recognizing cyber incidents is proposed, which is reduced to their identification. The methods for solving it are analyzed and a number of their significant shortcomings are identified, which make it difficult to use them in practice. An approach to solving the formulated problem of identifying cyber incidents by a SIEM system is proposed on the basis of forming a fuzzy knowledge base of the SIEM system about their features based on the collection of expert information and its further processing by applying the theory of fuzzy sets. The basic principles that should be used when developing a mathematical model for identifying cyber incidents by a SIEM system are formulated. A model of a fuzzy knowledge base of cyber incidents is proposed in the form of a multidimensional table with the features of cyber incidents represented by linguistic terms and classes that correspond to them. A representation of the fuzzy knowledge base (matrix) in the form of a system of fuzzy rules of the "IF-THEN" type is presented, and on their basis, by applying the min and max operations, a model for identifying cyber incidents by a SIEM system is proposed. It is concluded that it is expedient to use the model presented in the paper to protect information and communication systems in the conditions of incomplete and inaccurate information about cyber incidents arising in the course of their operation.
Effect of drilling parameters on hole quality in drilling of pultruded GFRP composite material: Surface roughness, thrust force and delamination factor
Authors: ENGİN Kaan Emre , YAKA Harun
Published: September 2023

Fiber reinforced polymer (FRP) composites are being used in a variety of areas. These materials need to be processed with some machining methods according to their usage areas, but their machinability is difficult. In this study, drilling is performed on glass fiber reinforced polymer (GFRP) composite produced by pultrusion with coated and uncoated drill. Then, surface roughness (SR), delamination factor (Fd) and thrust forces were investigated. Microstructures of chips formed during drilling were investigated and their effects on surface roughness were determined. Three distinct feed rates and cutting speeds were selected as machining parameters. Investigations showed that feed rate had a more significant effect on surface roughness, delamination factor and thrust force. It was understood that when the cutting speed increased, the surface roughness, thrust force and delamination factor decreased. Better results were obtained with TiN coated drills compared to uncoated drills.
Prediction of cetane numbers of pure biodiesels based on various fuel properties using multiple non-linear correlations
Authors: GÜLÜM Mert
Published: September 2023

Biodiesel has received considerable attention in recent years owing to its advantages over diesel fuel. Density, viscosity, flash point, heating value, and cetane number are among the most critical fuel properties of biodiesel. In the literature, using multiple linear regression, machine learning methods, and group contribution methods, some correlations have been derived to predict the cetane number of pure biodiesels depending on their properties (composition of fatty acid esters, number of carbon atoms, number of double bonds, molecular weight of the fatty acid esters, chain length, saponification number, iodine value, etc.). However, fewer researchers have attempted to establish a correlation between cetane number and other important fuel properties. Therefore, this study aims to employ multiple non-linear regression method for predicting the cetane number of pure biodiesels depending on the density, viscosity, flash point, and heating value. To obtain correlations, experimental data on fuel properties from the literature covering 100 different biodiesels (methyl and ethyl esters) were collected. The prediction performances of the suggested multiple non-linear correlations were compared to the multiple linear correlation frequently suggested in the literature. Reliable correlations with errors lower than 5% and high coefficient of determination values (r2) were derived.

Introduction: We aimed to define the characteristics of patients hospitalised in a palliative care unit and evaluate the role of palliative care services in the geriatric age group. The priorities and treatment approaches needed according to age groups were also evaluated. Materials and Methods: The records of patients aged 18 years and older who followed up with palliative care between 01/2020-12/2021 were reviewed retrospectively. Patients aged 18-64 were defined as “group-1”, patients aged 65-75 as “group-2”, patients aged 76-90 as “group-3”, and patients aged 91 and over as “group-4”. The patient’s age, sex, diagnosis, comorbidities, length of stay in the clinic, prognosis, pressure ulcers and immobilisation status were recorded and compared according to age groups. Results: A total of 560 patients were included. The mean age was 73.14±14.22 years, and 53.2% were women. 48.2% of patients were transferred to the palliative care unit from the intensive care unit. Groups-1, 2, 3, and 4 consisted of 139 (24.8%), 129 (23%), 254 (45.4%), and 38 (6.8%) patients, respectively. When patients were examined according to age group, there was a statistically significant difference between the groups in terms of sex, pressure ulcers, immobilisation, mean hospital stay in the palliative care, and prognosis (p=0.026, p≤.001, p=0.006, p≤.001, p≤.001). While 72% of patients were discharged from the palliative care unit, 28% died during admission. The prognosis was better in group-1 compared to other groups. Conclusion: Geriatric age and presence of chronic disease were the primary groups receiving palliative care. Access and integration of these patients to palliative care must be expanded. Keywords: Palliative Care; Geriatrics; Critical Care; Chronic Diseases; Health Services Accessibility.

Quantitative Analysis of Political Factors of Revolutionary Destabilization (A Systematic Review)
Authors: Korotayev A.V. , Zhdanov A.I.
Published: September 2023

The article presents a systematic review of the results of testing political factors of revolutionary destabilization in the works that the authors classify as the fifth generation of research on revolutions. The article demonstrates that according to the existing quantitative cross-national studies, the same political factors can have a different effect on the probability of armed uprisings, on the one hand, and unarmed revolutionary actions, on the other hand. The studies reviewed by the authors show that holding elections increases the risks of unarmed revolutionary destabilization. The diffusion effect in the modern world is more typical for unarmed than armed revolutions. Similarly, the long-serving leader acts as a trigger for unarmed rather than armed uprisings. In turn, armed revolutionary clashes occur especially often in countries characterized by ethnic and religious heterogeneity, where a significant part of the population is excluded from politics on ethno-religious grounds. The same applies to the countries that pursue a policy of discrimination directed against minorities. At the same time, there are factors that impact all types of revolutionary destabilization. The likelihood of both armed and unarmed revolutions is highest in countries with a political regime that lies in between full autocracy and full democracy, that is, in partial autocracies and partial democracies. Both armed and unarmed revolutions are more likely to occur if preceded by the similar events in the recent past (armed revolutionary uprisings increase the likelihood of new armed uprisings, while unarmed — new unarmed protests).

Published: September 2023

Asymptomatic bacteriuria is a common problem in pregnancy and is associated with the risk of preterm birth and pyelonephritis if untreated. This study aims to determine the prevalence and aetiology of asymptomatic bacteriuria and the susceptibility pattern in pregnant women attending antenatal clinics in a tertiary hospital in South-South Nigeria. Urine samples from 30 pregnant women were analysed using conventional microbiology techniques, and the mean age of the respondents was 29.57±5.89 years. The prevalence of asymptomatic bacteriuria in this study is 66.6%, with a higher prevalence in the third trimester (73.3%). The subjects aged 31-35 had the highest prevalence of Klebsiella pneumoniae as the common isolate, followed by Escherichia coli at 45% to 40%, respectively. Reflacine was more susceptible to Escherichia coli (87.5%), while ciprofloxacin was more susceptible to Klebsiella pneumoniae (88.8%) in this study. Asymptomatic bacteriuria is not uncommon among antenatal patients in the population studied. Routine urine culture tests should be conducted on all antenatal patients to identify any unsuspecting infection. This measure will go a long way in reducing maternal and obstetric complications associated with pregnancy, such as preterm labour and low birth weight babies.

Postmenopausal women are particularly affected by obesity. Although it is well documented that obesity is strongly associated with morbidity and mortality, less is known about the impact of obesity on health-related quality of life (HRQoL). The aim of this study was to investigate the relationship between body weight and the physical and mental components of health-related quality of life of the postmenopausal women attended at primary health care in Sarajevo Canton, Bosnia and Herzegovina. This cross-sectional study evaluated 200 postmenopausal women in two groups of 100 each (i.e. overweight/ obese and normal weight). The respondents were supposed to fill out a questionnaire that included questions about their age, years since menopause and the SF-36 questionnaire. Women were weighed and measured, and BMI was calculated. The mean values for the mental component summary were significantly lower in the overweight/obese (59.08±21.86) than in the normal weight group (67.05±19.02) (p=0.006). The mean values for the physical component summary were significantly lower in the overweight/obese (57.56 ±22.81) than in the normal weight group (67.38±21.85) (p=0.002). There was not significant relationship between body weight and the physical and mental components of health-related quality of life. Identification of predicting factors of HRQoL, such as body mass index can help to improve the HRQoL, of these women allowing planning practical interventions.

Titanium alloys are commonly used in different industries due to its high strength and less in weight. Even though the machinability of titanium alloys is very less, due to its high strength, it becomes more useful in aerospace and medical industries. In this paper, the performance of stationary and rotary copper electrodes on machining of Titanium alloy Ti-6Al-4V with Electro Discharge Machining (EDM) have been studied. Material removal rate (MRR), tool ware rate (TWR) and surface roughness (SR) were analyzed with three controllable input parameters such as pulse on time (Ton), Peak Current (Ip) and Gap Voltage (V). The design of experiment is chosen for the experimentation as the Box-Behnken response surface design method. The results are analyzed using grey relational analysis (GRA) coupled with firefly algorithm. In both the case of stationary and rotary electrode, it was revealed that gap voltage is significant for overall grey relational grade. The machining performance of Titanium alloy Ti-6Al-4V in the case of rotary mode of electrode is quite better as compared to the stationary mode of operation.

Aerodynamic behaviour of an object depends on several factors, namely shape, size and flow conditions. Thus, CFD simulations are an effective engineering tools that allows major contribution to understand the flow conditions around an object. This study aims to analyse the effect of two typesof spherical modelsthat aresphere and hemisphereon aerodynamics behaviour for different Reynolds number between 100,000 ≤ Re ≤ 800,000. Geometry models are generated using SolidWorkssoftwareand numerical solution is analysedusing ANSYS CFX. The numerical results are later compared with experimental data collected from wind tunnel. At the end of the study, the nature flow around spherical models of different Reynolds number are visualized. It is discovered that the flow behaviour around the spherical model changes as the Reynolds number increases. This finding is parallel with past researchers. These forecasts should assist engineers enhance the application of aerodynamic and hydrodynamic design.

Scientific relevance. Direct-acting antivirals have significantly improved the effectiveness of treatment for hepatitis C. However, Russia and the Eurasian Economic Union lack recommendations for the clinical development of medicinal products from this pharmacotherapeutic group.

Aim. The study aimed to analyse the requirements and recommendations for planning safety and efficacy clinical trials of direct-acting antivirals for chronic viral hepatitis C, outlined in the regulatory documents of the European Union and the United States.

Discussion. Upon analysing the requirements and recommendations, the authors explained the reasons behind choosing the target population and the design for the efficacy and confirmatory studies. The article covers the clinical development of direct-acting antivirals in special populations, including patients with hepatitis C and HIV co-infection, a liver transplant, and prior treatment experience. According to the authors, patients who achieved a sustained virological response should be followed up for a full year after the end of treatment in order to confirm the durability of their response. A dose-finding study should first identify a suitable dose range for monotherapy and, subsequently, for combined therapy. Current treatment regimens should be optimised, and studies should be conducted to reduce treatment duration.

Conclusions. The authors outlined the main approaches and a methodology for clinical trial programmes that should take into account the degree of correlation between the efficacy of direct-acting antivirals and the genotype/subtype of hepatitis C virus.

Published: September 2023

Purpose: The purpose of this research is to determine the effect of heel warming with a thermofor at two different temperatures before heel stick sampling in healthy term neonates on total crying and procedure durations.
Methods: This study was a randomized controlled trial. The sample for the research comprised 120 healthy term neonates with heel stick sampling performed by the same nurse. Neonates were randomized into control (n = 40), heel warming with a thermofor containing warm water (n = 40) and heel warming with a thermofor containing hot water (n = 40) three groups. In the study, to determine the efficacy of the heel warming intervention, neonates were recorded for six minutes before heel stick sampling and five minutes after heel puncture with a video camera.
Results: In the study, both the total procedure duration and total crying duration were statistically significantly shorter in the group with heel warming with hot water compared to the control group (KW = 6.088, p = 0.016; KW = 7.611, p = 0.006, respectively). However, in the group with heel warming with warm water, there was no significant difference in terms of total crying and procedure durations compared to both the control group and the group with heel warming using hot water (p> 0.05).
Conclusion: Before heel stick sampling in healthy term neonates, warming the heel with a thermofor containing hot water is effective in shortening the total crying and procedure durations.

Background: Observational studies have reported that individuals diagnosed with polycystic ovary syndrome (PCOS) face a heightened vulnerability to developing post-traumatic stress disorder (PTSD). However, it is unclear whether this relationship is causal. Consequently, we implemented a bidirectional Mendelian randomization (MR) analysis to examine the empirical causal association of PCOS and PTSD. Methods: We acquired genetic association data for PCOS through a comprehensive meta-analysis from several large-scale genome-wide association studies (GWASs), which enrolled 10,074 cases and 103,164 controls. For PTSD, we obtained data from a GWAS performed by the Psychiatric Genomics Consortium Posttraumatic Stress Disorder (PGC-PTSD) group. The study included a total of 23,212 cases of PTSD and 151,447 controls of European ancestry. For both PCOS and PTSD, we carefully selected genetic instruments that met the rigorous significance threshold (p < 5 × 10-8, r2 < 0.01). To investigate the causal association between PCOS and PTSD, we conducted bidirectional Mendelian randomization (MR) analyses. The primary analysis employed the inverse-variance weighted (IVW) method, complemented by alternative MR approaches such as the maximum-likelihood method, MR-Egger regression, Mendelian randomization-Robust Adjusted Profile Score (MR-RAPS), and MR Pleiotropy RESidual Sum and Outlier (MR-PRESSO) test. Sensitivity analyses were also carried out to verify the robustness of this association. Results: In this study, we identified and utilized 14 genetic variants as instruments for PCOS, while 2 genetic variants were selected as instruments for PTSD. Our findings demonstrated that a genetic predisposition to PCOS was significantly associated with an elevated risk of developing PTSD (odds ratio (OR) = 1.11, 95% confidence interval (CI): 1.03–1.19, p = 7.27 × 10-3 for IVW). MR-Egger regression analysis was performed, and the results did not provide evidence of directional pleiotropy (p intercept = 0.187). Sensitivity analyses utilizing alternative MR methods consistently yielded similar results, supporting the robustness of our findings. Furthermore, in the reverse MR analysis, we observed no significant association between genetic predisposition to PTSD and the risk of developing PCOS (OR = 1.15, 95% CI: 0.69–1.91, p = 0.586 for IVW). Comparable null associations were also observed when alternative MR methods were employed. Conclusions: Through a genetic epidemiological approach, we found that genetic predisposition to PCOS was associated with an increased risk of PTSD, suggesting a potential causal relationship between PCOS and PTSD. Nonetheless, further investigation is necessary to elucidate the underlying mechanism through which PCOS contributes to the development of PTSD.
