Digital initiatives are explored that relate not only to the technological and organizational aspects of airlines and their processes, but also those that affect all participants in aviation activities. The driving forces for adaptation to the standards set by the industry for all participants have been identified, namely the introduction of the latest information technologies and digital tools to position themselves in the competition for customers. A thorough examination of current aviation industry practices has demonstrated that digital development will remain key to restoring aircraft and flight operations to safer and more efficient operations. It was concluded that the development of digital operations through an integrated application ecosystem and connectivity tools will provide airlines with the necessary responsiveness to meet the new challenges and demands of the COVID-19 pandemic

The work discusses the practical application of an artificial neural network for solving complex, non-formalizable problems, such as pattern recognition, image processing, information processing, etc., as well as for controlling complex nonlinear dynamic objects. Artificial neural networks are based on the features of living neural networks, which allow them to solve various problems and are able to indicate the confidence level of each solution in a specific and logical way. In neural networks, all mathematical operations are carried out by a training program called a learning cycle

Electrical activity from the brain is captured using electrodes on the scalp. The primary goal is to differentiate EEG data between innocence and guilt. Data from 10 individuals has been collected. The raw EEG signals undergo signal processing via a band-pass filter. The crucial step involves extracting key features from these processed EEG signals, focusing on statistical parameters like mobility, activity, and complexity in the time domain. The classification into guilty or innocent categories is achieved using a k-nearest neighbor classifier. To validate the accuracy of the deception detection system, a 5-fold cross-validation method is applied to each subject. Performance metrics such as accuracy, sensitivity, and specificity are used to assess the classifier's effectiveness. Among three Hjorth parameters tested, mobility demonstrated the highest classification accuracy, reaching up to 96.7%.

A comparative study of the hepatoprotective activity of the substances Brassica rapa, Nigella sativa, Sambúcus nígra with comparison drugs C-4 and Phosphogliv in acute hepatitis induced by carbon tetrachloride (CCl4) was carried out in experiments. The results of a comparative assessment of the hepatoprotective activity of Brassica rapa, Nigella sativa, Sambúcus nígra substances with C-4 and Phosphogliv preparations showed a high degree of hepatoprotective properties of Brassica rapa substances at a dose of 20 mg/kg and Sambúcus nígra at a dose of 30 mg/kg, which in the future can be used to create a biologically active additive (dietary supplement) for treatment of diseases of the hepatobiliary system

Currently, in the structure of population mortality, 57% are diseases of the cardiovascular system, of which 49.3% are due to coronary heart disease (CHD). The study of coronary heart disease, and in particular unstable angina (UA), its complications and the effectiveness of treatment, dictates the need to study risk factors. Goal of work was studying the short-term outcomes of unstable angina in women and men with metabolic syndrome. We examined 58 patients with ischemic heart disease and metabolic syndrome who were treated in the Internal Diseases of the Pediatric Faculty department of SamSMU for the period from 2022 to 2023. Based on the data, it can be concluded that metabolic syndrome develops earlier in women than in men, as a result of which changes in the functioning of the cardiovascular system also appear earlier. Despite this, laboratory indicators indicate that, despite gender differences, there is a tendency to worsen the lipid spectrum and glycemic parameters in patients with unstable angina due to MS

One of the rapidly developing areas of clinical diagnostics in modern medicine is the study of the structuring processes of biological fluids - complex multicomponent systems that dynamically change during metabolic disorders and other pathological processes. Goal of work was to study the significance of the structure of blood serum in gynecology, in particular in patients with abnormal uterine bleeding. We examined 50 patients with AUB who were treated in the gynecological department of the multidisciplinary clinic of SamSMU for the period from 2022 to 2023. Analyzing the results of the study, we found that there is a significant connection between the structural organization of blood serum and the phenomena of AUB
