Background. Monitoring of physical and sexual development indicators using standards appropriate to age and sex, especially in children with chronic diseases is the most important element of management of children and adolescents with various pathologies because it allows managing the treatment process and improving it timely. Unfortunately, these issues have not been studied enough today. The purpose of the work is to determine the influence of somatic and mental diseases on the physical and sexual development impairments in school-age children. Materials and methods. Nine hundred and thirty-five patients aged 10–17 years (boys — 441, girls — 494) with the following pathology were examined: diabetes mellitus type 1, diffuse nontoxic goiter (DNG) with various menstrual disorders (girls with abnormal uterine bleeding), and girls with hypomenorrhea syndrome (HMS), mental disorders (functional and organic), systemic connective tissue dysplasia, secondary cardiomyopathy, juvenile idiopathic arthritis (JIA), systemic lupus erythematosus (SLE). The comparison group enrolled healthy children of the same age. Results. The presence of type 1 diabetes mellitus, diffuse nontoxic goiter were proved to negatively affect the somatosexual development of school-age children and contribute to the formation of disharmonious physical development (in 32.4 % of patients with diabetes mellitus 1 and 56.6 % of adolescents with DNG) and sexual maturation. It was established that 52.4 % of girls with gynecological pathology presented with harmonious physical development. Against the background of disharmony of physical development, girls are more likely to develop menstrual irregularities such as HMS. Harmonious physical development is registered in 50.8 % of patients with JIA. 67.25 % of people with JIA have normal growth rates. Exceedance of normal and lower values are observed in girls (p < 0.05). At the stages of puberty, the most common deviations in growth and body weight were observed in early puberty (100 %), the least often — in late puberty (42.8 %). In 56.8 % of patients with SLE, harmonious physical development was registered. The most common were as follows: overweight (33.3 %), decreased growth rate (17.6 %), and weight deficit (11.7 %). Based on the frequency of SLE, it was determined that the most vulnerable were puberty (91.0 %) and prepuberty (87.5 %). The onset of SLE in late puberty occurred in 26.3 % of cases. In patients with secondary cardiomyopathies and systemic connective tissue dysplasia, no significant statistical differences in age-related parameters were found. Most patients with mental disorders had a harmonious physical development (93.6 %). Among the violations of the latter, the deficit of body weight was most often determined (19.5 %).

Background. It is known that malnutrition significantly affects human life expectancy and leads to the emergence and development of non-communicable diseases. A balanced diet is a leading factor in the prevention of gastrointestinal diseases. The purpose was to investigate the state of actual nutrition, indicators of nutritional status and gastrointestinal morbidity in school-age children. Materials and methods. The study was conducted on the basis of secondary schools in Chernivtsi and MNPE “Chernivtsi Regional Children’s Clinical Hospital”. A questionnaire method was used with the compilation of individual menus and subsequent analysis of the chemical composition of diets in 162 students. Depending on the state of health, children were divided into groups: I (n = 90) — those with chronic gastrointestinal diseases, II (n = 44) — with functional gastrointestinal disorders, III (n = 28) — individuals without gastrointestinal pathology. Results. Chronic gastrointestinal pathology was diagnosed in 55.5 % of the examined children, functional gastrointestinal diseases — in 27.2 %. The most common chronic pathology is chronic gastroduodenitis. The majority of the surveyed children did not follow the diet, namely 56.5 % of children violated the frequency of intake, 69.2 % did not adhere to the intervals between meals. Most of patients (59.2 %) eat 3–5 times a day, 29.1 % of them eat 3–4 times a day, 30.1 % eat 4–5 times, and 11.7 % less than three times a day. One third of children do not have breakfast at home, and 19.5 % do not have a second breakfast at school. The caloric value of daily diets is lower than the normative indicators, it averages 2,337.64 ± 65.16 kcal and is insufficiently provided by the main components: proteins by 12 %, fats by 25 % and carbohydrates by 63 %. Macro- and micronutrient deficiency is also registered in 53.1 % of children, especially of calcium, phosphorus, copper, zinc, and iodine. Children of groups II and III are less likely to eat fast food compared to those of group I (34.1 and 32.1 vs. 53.3 %, p < 0.05). Conclusions. The diet and nutrition of school-age children with gastrointestinal pathology does not meet hygienic requirements and not only does not provide primary prevention of non-communicable diseases, but, on the contrary, is a risk factor for the latter.
Anticoagulant therapy in patients with nonvalvular atrial fibrillation in real clinical practice: the problem of therapy safety and treatment adherence
Authors: Khaniukov O. , Smolianova O. 
Published: September 2021

Atrial fibrillation (AF) is the most common arrhythmia in the adult population, and the number of patients with this arrhythmia will increase in the future. As a result, the number of patients taking anticoagulants (ACs), which are considered "high alert medication" is constantly increasing.
The aim. To highlight the problems of ACs use in patients with non-valvular AF in real clinical practice, to consider the therapy safety and treatment adherence.
The main body. Approval of new oral ACs has provided more options to clinicians and patients, but even with their use, errors are possible that increase the risk of bleeding. Mistakes can be made by both patients and doctors. The introduction of training as a mandatory element in the complex therapy of AF helps to reduce the number of errors that the patient could make. The clinical condition, the availability of monitoring and the patient's wishes for treatment may change over time, and this may lead to the need to switch the AC, which is potentially dangerous in terms of side effects. The risk of bleeding increases regardless of the direction of change of AC - the very fact of transition is important. Doctor`s errors play a significant role in the risk increase at this stage, and it is important to raise their awareness of the rules for the ACs switch to avoid bleeding. The article presents the rules of transition from one oral AC to another, following which doctors will minimize the risk of side effects in clinical practice.
Conclusion. The use of AC for patients with AF is life-saving, but if used improperly, life-threatening side effects can occur. According to research, in many cases, the development of the latter could be prevented primarily through patient education and the proper doctor training.

Наибольшей перспективой для почвозащитной системы ведения горного садоводства обладает мульчирующая система ухода за почвой. При этом в качестве мульчматериала следует использовать скошенную и измельченную растительность растительность. Наибольший эффект от мульчирования растительности в условиях горного садоводства достигается при применении косилочных устройств, использование которых позволяет наиболее полно реализовать дерново-перегнойную систему содержания почвы в садах.
Для реализации указанной системы содержания почвы в садах нами разработана и испытана ротационная косилка эшелонированного резания.
В результате измерения физических характеристик почвы и обеспе-ченности ее влагой установлено, что насыщенный корнями слой почвы на глубине 30 см самый рыхлый при мульчировании. В относительном выражении увеличение содержания влаги в метровом слое почвы террас выше на 24,6%, чем без применения предлагаемых агротехнических приемов. Мульчирование снижает сток в 3...4,5 раза, а смыв в 3,8...6 раз. Использование разработанной косилки обеспечивает: экономический эффект за счет повышения урожайности и качества плодов в размере 5,52 тыс. руб/га; чистый дисконтированный доход за период эксплуатации (5 лет) в 11866,42 тыс. руб. на площади 100 га; снижение себестоимости выполнения технологического процесса в 2 раза; снижение трудовых затрат в 1,5 раза; снижение эксплуатационных затрат в 2,1 раза.

Published: September 2021

Abstract
In this article, we present an efficient method for solving Abel’s integral equations. This important equation is consisting of an integral equation that is modeling many problems in literature. Our proposed method is based on first taking the truncated Taylor expansions of the solution function and fractional derivatives, then substituting their matrix forms into the equation. The main character behind this technique’s approach is that it reduces such problems to solving a system of algebraic equations, thus greatly simplifying the problem. Numerical examples are used to illustrate the preciseness and effectiveness of the proposed method. Figures and tables are demonstrated to solutions impress. Also, all numerical examples are solved with the aid of Maple.

Abstract
The purpose of this study was to examine the accuracy of HR measurements by the PTN-104 sensor in comparison to the fingertip pulse oximeter, which is a photoplethysmographic sensor (PPG). Twelve healthy participants underwent the same protocol during a single visit. Measurements were taken after each participant completed an initial rest period of 5 minutes and after 1-minute of exercising comprising of 30 squats. Each subject had the PTN-104 sensor attached to the index finger and a fingertip pulse oximeter to the opposite one. When examining the data in aggregate, there was a strong correlation between the PTN-104 sensor and PPG for HR (r = 0.988) with a mean bias of −2.55 bpm (95 % LoA +5.0, −10.1). The PTN-104 sensor satisfied validity criteria for HR monitors, however, showed a lower accuracy for measurements at rest, which is surprising. Due to the noticed limitations, this study should be repeated with a larger group of subjects and the PTN-104 sensor should be compared to the gold standard method for measuring HR, which is ECG.
A Novel Three-stage Feature Fusion Methodology and its Application in Degradation State Identification for Hydraulic Pumps
Authors: Pei Mochao , Li Hongru , Yu He 
Published: September 2021

Abstract
The performance of feature is essential to the degradation state identification for hydraulic pumps. The initial feature set extracted from the vibration signal of the hydraulic pump is often high-dimensional and contains redundant information, which undermines the effectiveness of the feature set. The novel three-stage feature fusion scheme proposed in this paper aims to enhance the performance of the original features extracted from the vibration signal. First, sparse local Fisher discriminant analysis (SLFDA) performs intra-set fusion within the two original feature sets, respectively. SLFDA has a good effect on samples with intra-class multimodality, and the feature set fused by it has obvious multivariate normal distribution characteristics, which is conducive to the next fusion. Second, our modified intra-class correlation analysis (MICA) is used to fuse two feature sets in the second stage. MICA is a CCA (Canonical correlation analysis) -based method. A new class matrix is used to modify the covariance matrix between two feature sets, which allows MICA to conveniently inherit the discriminating structure while fusing features. Finally, we propose a feature selection algorithm based on kernel local Fisher discriminant analysis (KLFDA) and kernel canonical correlation analysis (KCCA) to select the desired features. This algorithm based on Max-Relevance and Min-Redundancy (mRMR) framework solves the problem that CCA cannot properly evaluate the correlation between features and the class variable, as well as accurately evaluates the correlation among features. Based on the experimental data, the proposed method is compared with several popular methods, and the feature fusion methods used in some previous studies related to the fault diagnosis of rotating machinery are compared with it as well. The results show that the fusion effectiveness of our method is better than other methods, which obtains higher recognition accuracy.
Mixed-mode Method Used for Pt100 Static Transfer Function Linearization
Authors: Jovanović Jelena , Denić Dragan 
Published: September 2021

Abstract
Pt100 is a resistance temperature detector characterized by a relatively linear resistance/temperature relationship in a narrow temperature range. However, the Pt100 sensor shows a certain degree of static transfer function nonlinearity of 4.42 % in the range between −200 °C and 850 °C, which is unacceptable for some applications. As a solution to this problem, a mixed-mode linearization method based on a special dual-stage piecewise linear ADC design is proposed in this paper. The first stage of the proposed dual-stage piecewise linear ADC is performed with a low-complex and low-power flash ADC of a novel sequential design. The novelty of the proposed sequential design is reflected in the fact that the number of employed comparators is equal to the flash ADC resolution. The second stage is performed with a delta-sigma ADC with a differential input and differential reference. Using the 6-bit flash ADC of novel design and the 24-bit delta-sigma ADC, the nonlinearity error is reduced to 2.6·10−3 %, in the range between −200 °C and 850 °C. Two more ranges are examined, and the following results are obtained: in the range between 0 °C and 500 °C, the nonlinearity error is reduced from 1.99 % to 5·10−4 %, while in the range between −50 °C and 150 °C, the nonlinearity error is reduced from 0.755 % to 2.15·10−4 %.
What is the Sustainable Level of Banks’ Credit Losses and Provisions?
Authors: Malovaná Simona , Tesařová Žaneta 
Published: September 2021

Abstract
In this paper, we estimate the sustainable level of lifetime expected credit losses and provisions and assess the procyclicality of banks’ credit losses and provisions in the Czech Republic. Further, we discuss the implications of the results for provisioning in stage 3 under the IFRS 9. Based on the estimation results, we can identify periods of insufficient provisioning when the actual values were below the sustainable levels. Additionally, we show that credit losses and provisions behave procyclically (i.e., decrease with a rising output gap and increase with a falling output gap) while banks recognize impaired credit losses and create provisions with a delay of three to four quarters after the output gap starts shrinking. Such a delay may result in a sharp increase in lifetime expected credit losses and provisioning in response to a deterioration in economic conditions under the IFRS 9 regime.

Abstract
More than a thousand laparoscopic fundoplication operations for hiatal hernia (HH) have been performed at the Clinic of the Bashkir State Medical University over the period between 2000 and 2019 and the results of surgical treatment of 502 patients were analyzed. Our research results indicate that routine instrumental methods used in hiatal hernia diagnosis provide valuable information, however only their combined application allows us to establish the correct diagnosis in all patients. Authors propose a new original X-ray balloon method that allows to improve the quality of diagnosis of hiatal hernia significantly. Balloon X-ray allows us to establish the true dimensions of the hiatus and select the most appropriate treatment accordingly. Isolated fundoplication without plastic of esophageal opening was performed in 180 patients. Surgical correction of the hiatus was performed on 322 patients. Diaphragmcrouroraphy was carried out in 199 cases, in 123 cases mesh implants were used to support the crus of the diaphragm. In 215 cases, simultaneous surgical procedures were performed to treat multiple abdominal pathology. We studied the changes in quality of life of 100 patients with hiatal hernia before and after laparoscopic esophagofundoplication by comparing the results of the survey (questionnaires) and medical examination of the cardiac sphincter of the esophagus function. The vast majority of patients demonstrated a significant improvement in the cardiac closure function, a decrease in the frequency and severity of gastroesophageal reflux, and reduced signs of reflux esophagitis.

ІНТЕРПРЕТАЦІЯ ІМПЛІЦИТНОЇ СЕМАНТИКИ АНТРОПОНІМІВ ПОЛІТИЧНОГО ДИСКУРСУ
Authors: Pechko Nina 
Published: September 2021

Стаття досліджує імпліцитний аспект політичного дискурсу через аналіз семантичних імплікатур антропонімів політичного дискурсу. Останні включають офіційні (імена, прізвища) та неофіційні (прізвиська, прізвиськові утворення, псевдоніми) найменування відомих політичних діячів, глав держав та урядів та є одиницями, відповідно, первинної та вторинної номінації, що визначає різні підходи до їх вивчення та шляхи інтерпретації семантичних імплікатур, які вони репродукують. Визначено, що при дослідженні офіційних найменувань політичних лідерів найбільш дієвим є етимологічний та семасіологічний підходи. Саме вони дають змогу прослідкувати походження конкретного антропоніма та виокремити імпліцитні семантичні елементи шляхом аналізу значення його дериваційних складових. Семантичне значення таких ономастичних одиниць є специфічним: воно не відбиває понять, а лише вказує на первісну семантику – мотиви номінації. Такі семантичні імплікатури, як правило, є безвідносні до персони номінанта, особистісно невмотивовані, почасту містять нейтральну позалінгвальну інформацію. При цьому вони є невід’ємними елементами цілісного семантичного значення антропоніму.
Доведено, що вивчення неофіційних антропонімів політичного дискурсу вимагає застосування прагматичного підходу, оскільки утворення прізвиськ та прізвиськових утворень зумовлене екстралінгвальними чинниками, є прагматично та функціонально вмотивованим. З’ясовано, що семантичні імплікатури таких неофійних найменувань містять позитивну та негативну конотації й у гіперболізованому вигляді вказують на характерні особистісні риси номінанта, виокремлюють його з-поміж інших, ретранслюють інформацію про специфіку та основні моменти його політичної кар’єри.
MODERN ASPECT OF UKRAINIAN POPULISM: POLITICAL AND SOCIAL ASPECT
Authors: Kiyanka Iryna 
Published: September 2021

The study of populism is actualized by the presence of a social order from interested political actors who use populism to implement their programs and in the struggle for power, focusing on the possibilities of change and reform. The relevance of the study is obvious given the lack of comprehensive study of populism in Ukraine, proper political evaluation of previous studies, rethinking some theses of individual researchers, and especially in connection with its actualization as one of the popular principles in action, behavior in modern political practice and our state. Today in Ukraine, the intensification and emergence of new manifestations of populism have become a sign of a general long-term failure on the path of technological modernization, in efforts to achieve rapid economic growth and in the fight against corruption. The tendency to the increasingly negative attitude of many citizens to complex and compromise procedures of democratic institutions, the desire for quick and simple solutions, intolerance of different views contain a double threat - to roll into anarchy or establish an authoritarian regime. In Ukrainian literature interest in populism appeared in the late 1990s. The initial study was the basis of his reception of analytical findings Western scholars. Today domestic historiography populism presented a number of papers in the form of articles. Amid the general characteristics of the phenomenon of populism, based primarily on the legacy of Western political scientists, highlights particular issues such as manifestations of populism in the Ukrainian national movement, modern Ukrainian politics populist methods of political struggle, philosophical discourse of the concept. Thus, populism can be considered an inevitable companion of political freedom and democracy. In some places, it is a force that promotes political participation and reform in the interests of many low-status social groups. By inclining to oppose the rights of the majority to the interests and rights of certain minorities, populism can be a threat to the rule of law and basic political and civil liberties. Wherever populist leaders gained power, it became authoritarian, accompanied by abuses and oppression (but not destruction) of the opposition.
