ASEAN as an Optimal/Nonoptimal Currency Area
Authors: Merło Paweł , Kułak Radosław , Warzocha Zbigniew
Published: January 2022

Economists have been arguing to this day about the benefits and risks of introducing a community currency. It is very difficult to clearly determine which side is right. Most often, scientists refer to the example of the so-called Eurozone, but it is still far from reaching an agreement between supporters and opponents of such a solution. This paper presents the issues of monetary integration in ASEAN+3 (i.e. ASEAN member countries, China, South Korea, and Japan) in terms of the optimal currency area and other necessary conditions for the creation of a sustainable development region. The researchers argue about whether ASEAN+3 should introduce a single currency. Some suggest that the group meets several OCA theory criteria, i.e. labour mobility and economic openness. According to the results of the study, ASEAN+3 is an economically diverse area and there is a lack of institutions enabling effective monetary integration in the short term. Optimization assumptions included in the analysis determine the real chances of development and survival within the currency area. The author's analysis has indicated that ASEAN+3 should not introduce a single currency for three reasons: failure to meet the optimization criteria, diversification of socio-economic development, lack of an institutional framework and inconsistency in the perception of monetary integration. On the other hand, it should be noted that a single currency could contribute to increasing the monetary security of the entire South-East Asian region, which means that the ​​monetary integration may be a long-term idea.

However, the stability of tax revenue affects the balance of public finances and the ability to meet public obligations. The aim of this study is to evaluate the stability of tax revenue in Poland’s national budget in 2004-2020. The research results indicate that both the amount and the structure of tax revenue in the national budget in 2004-2020 were stable.
Features of driving of the steering wheel driving cars
Authors:   Kharkiv National Automobile and Road University, Dityatyev Oleksandr
Published: January 2022

Existing methods of diagnosing steering can be characterized by low efficiency. For various reasons, both declarative and actual (supported by the equipment) methods, as a rule, have low accuracy and inability to localize faults. The car's built-in diagnostics cannot affect the situation due to the small number of sensors in the steering system. The reasons for the low accuracy of the methods include design features, low availability of components (low maintainability). Difficulties in localization of malfunctions are caused by the structural scheme which is characterized by parallel - consecutive construction. The parameters of diagnostic methods are analyzed, the proposed method is based on the structure of the steering, in the implementation of which test effects are applied to the steered wheels. In total it is necessary to carry out three measurements of backlashes and as a result of mathematical processing of results it becomes possible to localize malfunction in three links of consecutive elements of the steering mechanism or a steering drive. In accordance with this approach, steering is considered as a set of three structures - parallel and two sequential. Rack and pinion steering was used as a model. Here, the parallel structure includes elements of the steering linkage: swing arm, left and right; steering rod, left and right; steering rack - left and right hinges. The sequential structure - left, includes a swing arm, left; steering rod, left; steering rack hinge, left; steering gear, steering shaft, steering wheel. Accordingly, the sequential structure of the right includes similar elements with the attribute "right". The structure of the steering play is considered in a similar way. As a result, it becomes possible to obtain a transformed system of three algebraic equations connecting clearances in three groups of mates and backlashes in parallel and two sequential steering structures. To measure the backlash, the turntables of the BOSCH FWA 4410 stand were used; in another version, the wheels were hung out. As a result of tests carried out on VW GOLF, VW PASSAT and RENAULT 25 vehicles with significant mileage, data was obtained indicating the need for technical interventions on localized groups of interfaces.

Published: January 2022

This article provides statistical data on the number of road accidents and their consequences (deaths and/or injuries) in all regions of Ukraine in 2021 as compared to the same period in 2020. Regions with a decrease in road traffic accident rates (Zakarpattya region, 9.6% decrease) and their percentage increase (Zhytomyr region, 56.1% increase) are highlighted. Based on the analysis of statistical data, it is estimated that the number of road traffic accidents in the country during this period increased by 19.6%. But as a positive phenomenon, the number of injuries and/or fatalities in these road accidents decreased by 17.2%. The article analyses and gives concrete examples of the use of some legally adopted road traffic control devices in the regional center of Ukraine - Zhytomyr city (traffic lights, road signs and road markings). Shows incidents of their use which are characterized by violations of traffic rules (Sections 8.1., 8.2, 8.3, 8.4, 8.7, Sections 33 "Traffic signs" and 34 "Traffic lanes"), DSTU 2587:2021 "Traffic lanes. General Technical Conditions", DSTU 4100:2021 "Road Safety. Road Signs". At the same time there are situations when road signs are in contradiction, which is categorically unacceptable. It also shows the cases where traffic signs are installed in a shape and design that is not included in traffic regulations and the relevant standard. It was concluded that the use of the above road traffic control devices in violation of the conditions of their installation (application) can lead to misinformation of road users, create additional informational and emotional pressure on them, contribute to increased fatigue, which consequently increases the probability of occurrence of road accidents and increases their importance.

The article proposes reducing the redundancy of the neural network and the need to reduce the number of neurons in the hidden layer for a given level of network learning error. The minimum number of neurons of the hidden layer for the case of 11 monitoring standard sensors, the parameters of the automobile and tractor engine (ATE) and five classes of typical defects of the ATE nodes can be reduced to 5-7 with a high quality of recognition of the state of the ATE engine. The goal is to provide an expanded reliable knowledge base, the speed of information processing, the accuracy of the resulting technical diagnosis and the ability to quickly determine the technical state of an automotive engine in the mode real time. The basis of the proposed method is to ensure obtaining an extended reliable knowledge base, the speed of information processing, the accuracy of the obtained technical diagnosis and the ability to quickly determine the technical state of an ATE engine in real time. A feature of the proposed method is the use of voltages obtained in an artificial neural network from sensors that are standard in an ATE engine as input signals, and additionally indicate the output signal of the fuel cut-off device, provided for one step, containing a winding of a normally closed electromagnetic valve, which redirects fuel to the drain line. The use of the algorithm for identifying the values of the indicators of operating modes and malfunctions of the cylinder-piston group is the result of the analysis of an artificial neural network, which receive the results of the diagnostic parameters of the automotive engine. Having studied the artificial neural network 1 with different volumes of training data, we obtained the dependence of the change in the reliability of the result on the size of the training data and the reliability of the recognition result is 91.2%, the optimal amount of training data is 1200. Having examined the artificial neural network 2 with different volumes of training data, we obtained the dependence of the change in the reliability the result from the size of the training data and the reliability of the recognition result is 86.5%, the optimal amount of training data is from 10 to 15. The results obtained show the fundamental possibility of creating predictive models of units and assemblies of the tested automotive engines. The model can be created using the apparatus of artificial neural networks and using a fairly large database of tests performed.

The article considers the change of the radius of the instantaneous center of rotation of a car moving along a curved trajectory during braking, taking into account the lateral input of the wheels of both axles of cars, both equipped with electronic tracking systems and not equipped with such. A criterion for assessing the controllability of cars moving on a curved trajectory in a braked state, by comparing the ratio of the current speed of the car to the longitudinal base with the ratio of the coefficients of lateral tire input to the product of the longitudinal base of the car, mass and cosines. It is established that the radius of instantaneous rotation of the longitudinal axis of the car moving along a curved trajectory during braking depends on the speed of the center of mass of the car, the coefficient of axle distribution of braking force, physical characteristics of applied tires, steering wheel angle and design and weight parameters. As a result, it allows you to set controllability. The authors obtained dependences that will create new algorithms for the operation of modern electronic control systems for stabilizing the longitudinal axis of a braked car, taking into account the speed of the car, its design and weight characteristics, the main characteristics of its braking system (coefficient of axle braking force distribution), physical characteristics used tires on wheels and connect them to the angles of the steered wheels, controlling the deviation of the longitudinal axis, which allows the driver to maintain the possibility of quite sharp maneuvers directly in the braking process, moving along a curved trajectory.

BUSINESS ETHICS. CORRUPTION PERCEPTION ANALYSIS
Authors:   Transilvania University of Brașov, Zamfirache Alexandra
Published: January 2022

This paper examines corruption from the perspective of business ethics. It is known that corruption negatively affects the development of countries in several ways: it reduces growth, chases away foreign investors and channels investments, loans and aid funds, the so-called White Elephant Projects. Corruption has a very high price for the poorest, who are denied access to basic goods and services, and this paper shows that the poor suffer the most from corruption. Based on the annual index provided by Transparency International, it can be observed that, in general, some of the richest countries in the world (like: Finland, Denmark, New Zealand, Canada, Iceland, Singapore and Sweden) consistently record a low level of corruption.

Published: January 2022

Background: The effectiveness of glucose-lowering drugs (GLDs) is unknown among patients with dementia. Objective: To analyze all-cause mortality among users of six GLDs in dementia and dementia-free subjects, respectively. Methods: This was a longitudinal open-cohort registry-based study using data from the Swedish Dementia Registry, Total Population Register, and four supplemental registers providing data on dementia status, drug usage, confounders, and mortality. The cohort comprised 132,402 subjects with diabetes at baseline, of which 11,401 (8.6%) had dementia and 121,001 (91.4%) were dementia-free. Subsequently, comparable dementia – dementia-free pairs were sampled. Then, as-treated and intention-to-treat exposures to metformin, insulin, sulfonylurea, dipeptidyl-peptidase-4 inhibitors, glucagon-like peptide-1 analogues (GLP-1a), and sodium-glucose cotransporter-2 inhibitors (SGLT-2i) were analyzed in the parallel dementia and dementia-free cohorts. Confounding was addressed using inverse-probability weighting and propensity-score matching, and flexible parametric survival models were used to produce hazard ratios (HR) and 95% confidence intervals (CI) of the association between GLDs and all-cause mortality. Results: In the as-treated models, increased mortality was observed among insulin users with dementia (HR 1.34 [95%CI 1.24–1.45]) as well as in dementia-free subjects (1.54 [1.10–1.55]). Conversely, sulfonylurea was associated with higher mortality only in dementia subjects (1.19 [1.01–1.42]). GLP-1a (0.44 [0.25–0.78]) and SGLT-2i users with dementia (0.43 [0.23–0.80]) experienced lower mortality compared to non-users. Conclusion: Insulin and sulfonylurea carried higher mortality risk among dementia patients, while GLP-1a and SGLT-2i were associated with lower risk. GLD-associated mortality varied between dementia and comparable dementia-free subjects. Further studies are needed to optimize GLD use in dementia patients.

Published: January 2022

Background: Chronic alcohol consumption can alter the structure of the central nervous system and disrupt cognitive function. Alcoholics are more likely to develop neurodegenerative disorders such as Alzheimer’s disease (AD) and Parkinson’s disease (PD). However, the role of alcohol in promoting neurotoxicity and neurodegeneration remains unclear. Objective: In this study, we aimed at estimating the effects of chronic binge alcohol exposure on brain transcriptome and behavior changes in a chronic “Drinking in the Dark” (DID) mouse model. Methods: The adult C57BL/6J male mice were exposed to alcohol for 4 weeks. RNA-seq was applied to assess the effects of chronic alcohol exposure on transcriptome in brain. The open field test and novel object recognition test were used to assess the changes of anxiety level, locomotive function, and short-term memory induced by alcohol. RNA-seq analysis revealed that chronic alcohol exposure caused significant change in the brain transcriptome, especially in prefrontal cortex. Results: The gene dysregulation caused by chronic alcohol exposure includes pathways related to mitochondrial energy metabolism (such as oxidative phosphorylation) and multiple neurodegenerative diseases (such as AD and PD). Furthermore, the pathway and network analyses suggest that the genes involved in mitochondrial energy metabolism, ubiquitin-proteasome system, Wnt signaling pathway, and microtubules may attribute to the neurotoxicity and neurodegeneration caused by chronic alcohol consumption. Additionally, locomotive function was also significantly impaired. Conclusion: This work provides gene transcriptional profile data for future research on alcohol-induced neurodegenerative diseases, especially AD and PD.
A 4 × 4 array multichannel magnetic stimulation system using submillimeter sized planar square spiral coils: The spatial distribution of electromagnetic field
Authors: Tian Lei , Song Limei , Zheng Yu , Wang Jinhai
Published: January 2022

Multi-coil magnetic stimulation has advantages over single-coil magnetic stimulation, such as more accurate targeting and larger stimulation range. In this paper, a 4 × 4 array multichannel magnetic stimulation system based on a submillimeter planar square spiral coil is proposed. The effects of multiple currents with different directions on the electromagnetic field strength and the focusing zone of the array-structured magnetic stimulation system are studied. The spatial distribution characteristics of the electromagnetic field are discussed. In addition, a method is proposed that can predict the spatial distributions of the electric and magnetic fields when currents in different directions are applied to the array-structured magnetic stimulation system. The study results show that in the section of z = 2 μm, the maximum and average magnetic field strengths of the array-structured magnetic stimulation system are 6.39 mT and 2.68 mT, respectively. The maximum and average electric field strengths are 614.7 mV/m and 122.82 mV/m, respectively, where 84.39% of the measured electric field values are greater than 73 mV/m. The average magnetic field strength of the focusing zone, i.e., the zone in between the two coils, is 3.38 mT with a mean square deviation of 0.18. Therefore, the array-structured multi-channel magnetic stimulation system based on a planar square spiral coil can have a small size of 412 μm × 412 μm × 1.7 μm, which helps improving the spatial distribution of electromagnetic field and increase the effectiveness of magnetic stimulation. The main contribution of this paper is a method for designing multichannel micro-magnetic stimulation devices.

Authors: Ai Mengmeng , Liu Wenhui , Shan Yi
Published: January 2022

In the process of Ultra high voltage direct current (UHVDC) transmission, the direct current (DC) bias of power transformer is easily induced, which makes the transformer exciting current distorted, the ferromagnetic material saturated and the magnetic leakage increased, and then leads to the increase of core vibration and noise. Aiming at this problem, taking a 240 MVA, 330 kV three-phase five-column power transformer as an example, the coupling of the electromagnetic field, structural force field and acoustic field is studied, and the influence of DC bias on vibration and noise of power transformer core is analyzed in this paper. According to the magnetic density and electric density of transformer core under different magnetic bias degree, the structural force field is solved, and the displacement and surface acceleration of core are obtained, which can be as the excitation of sound field to determine the noise distribution of transformer. In order to avoid the natural frequencies which easily cause resonance, the modal analysis is needed to obtain the natural frequencies and modal modes of the core. The transformer noise under no-load and DC bias conditions of the prototype is tested experimentally and compared with the theoretical calculation, the results prove the accuracy of the simulation calculation method in this paper.
An extended WASPAS approach for teaching quality evaluation based on pythagorean fuzzy reducible weighted Maclaurin symmetric mean
Authors: Wei Dongmei , Rong Yuan , Garg Harish , Liu Jun
Published: January 2022

Teaching quality evaluation (TQE) can not only improve teachers’ teaching skills, but also provide an important reference for school teaching management departments to formulate teaching reform measures and strengthen teaching management. TQE is a process of grading and ranking a given teachers based on the comprehensive consideration of multiple evaluation criteria by expert. The Maclaurin symmetric mean (MSM), as a powerful aggregation function, can capture the correlation among multiple input data more efficient. Although multitude weighted MSM operators have been developed to handle the Pythagorean fuzzy decision issues, these above operators do not possess the idempotency and reducibility during the procedure of information fusion. To conquer these defects, we present the Pythagorean fuzzy reducible weighted MSM (PFRWMSM) operator and Pythagorean fuzzy reducible weighted geometric MSM (PFRWGMSM) operator to fuse Pythagorean fuzzy assessment information. Meanwhile, several worthwhile properties and especial cases of the developed operators are explored at length. Afterwards, we develop a novel Pythagorean fuzzy entropy based upon knowledge measure to ascertain the weights of attribute. Furthermore, an extended weighted aggregated sum product assessment (WASPAS) method is developed by combining the PFRWMSM operator, PFRWGMSM operator and entropy to settle the decision problems of unknown weight information. The efficiency of the proffered method is demonstrated by a teaching quality evaluation issue, as well as the discussion of sensitivity analysis for decision outcomes. Consequently, a comparative study of the presented method with the extant Pythagorean fuzzy approaches is conducted to display the superiority of the propounded approach.
Diagnosis of infertility from adenomyosis and endometriosis through entroxon based intelligent water drop back propagation neural networks
Authors: Vijayalakshmi P. , Muthumanickam K. , Karthik G. , Sakthivel S.
Published: January 2022

Adenomyosis is an abnormality in the uterine wall of women that adversely affects their normal life style. If not treated properly, it may lead to severe health issues. The symptoms of adenomyosis are identified from MRI images. It is a gynaecological disease that may lead to infertility. The presence of red dots in the uterus is the major symptom of adenomyosis. The difference in the extent of these red dots extracted from MRI images shows how significant the deviation from normality is. Thus, we proposed an entroxon-based bio-inspired intelligent water drop back-propagation neural network (BIWDNN) model to discover the probability of infertility being caused by adenomyosis and endometriosis. First, vital features from the images are extracted and segmented, and then they are classified using the fuzzy C-means clustering algorithm. The extracted features are then attributed and compared with a normal person’s extracted attributes. The proposed BIWDNN model is evaluated using training and testing datasets and the predictions are estimated using the testing dataset. The proposed model produces an improved diagnostic precision rate on infertility.
Handling qualitative preferences in SPARQL over virtual ontology-based data access
Authors: Goncalves Marlene , Chaves-Fraga David , Corcho Oscar
Published: January 2022

With the increase of data volume in heterogeneous datasets that are being published following Open Data initiatives, new operators are necessary to help users to find the subset of data that best satisfies their preference criteria. Quantitative approaches such as top-k queries may not be the most appropriate approaches as they require the user to assign weights that may not be known beforehand to a scoring function. Unlike the quantitative approach, under the qualitative approach, which includes the well-known skyline, preference criteria are more intuitive in certain cases and can be expressed more naturally. In this paper, we address the problem of evaluating SPARQL qualitative preference queries over an Ontology-Based Data Access (OBDA) approach, which provides uniform access over multiple and heterogeneous data sources. Our main contribution is Morph-Skyline++, a framework for processing SPARQL qualitative preferences by directly querying relational databases. Our framework implements a technique that translates SPARQL qualitative preference queries directly into queries that can be evaluated by a relational database management system. We evaluate our approach over different scenarios, reporting the effects of data distribution, data size, and query complexity on the performance of our proposed technique in comparison with state-of-the-art techniques. Obtained results suggest that the execution time can be reduced by up to two orders of magnitude in comparison to current techniques scaling up to larger datasets while identifying precisely the result set.

Питьевая вода является особо важным элементом в поддержании сил и здоровья каждого человека. Основными функциями пресной воды является утоление жажды и обеспечение организма человека полезными веществами. Вместе с ней туда попадают и токсичные вещества. Поэтому чистая питьевая вода нуждается в особо бережном отношении и охране, так как от её состояния (и особенно от химического состава) зависит здоровье всех слоев населения. Охрана питьевой воды осуществляется различными методами мониторинга её состава. Одним из таких является метод атомно-эмиссионной спектрометрии с индуктивно связанной плазмой, который зарекомендовал себя как высококачественный и чувствительный метод определения содержания химических веществ в питьевой воде. Его применению и оценке состояния питьевой воды с его помощью и посвящена данная научно-исследовательская работа. Применение такого метода позволит точно обнаруживать нарушения в содержании химических веществ, определять территориальное распределение элементно-ассоциированных гигиенических проблем питьевой воды при проведении комплексного мультицентрового мониторинга, что позволит избежать неблагоприятных последствий.

Autoimmune polyglandular syndrome-1 (APS-1)also known as autoimmune polyendocrinopathy candidiasis ectodermal dystrophy is a rare autosomal recessive disorder caused by mutation of AIRE gene on chromosome 21q22.3 with an overall prevalence of <1:100,000. Here, we present a 16-year-old male having clinical history of evolution of symptoms for oral candidiasis, hypoparathyroidism, and adrenal insufficiency (AI). He developed rare endocrine and non-endocrine manifestations such as type-1 diabetes (T1D) and autoimmune hepatitis, respectively. The patient while on hormone replacement therapy along with immunosuppressants developed liver cirrhosis and portal hypertension with esophageal varices and candidiasis. Subsequently, he was admitted for complaints of cough, cold and fever and was confirmed to be affected by SARS-CoV-2 by reverse transcription-polymerase chain reaction method. In his prolonged ICU stay of 26 days, he required oxygen therapy, intravenous glucocorticoids, remdesivir, low molecular weight heparin, and hemodynamic support with inotropes. His medical management with subcutaneous insulin therapy and azathioprine was continued. He was discharged after complete resolution of symptoms and negative tests for SARS-CoV-2 and was advised radiological and clinical follow-up. Reports suggest that risk of severe COVID does not increase in patients with AI or autoimmunity. However, our patient possibly developed severe COVID not only due to AI and autoimmunity but also associated rare manifestations like hyperglycemia due to T1D and cirrhosis. Thus, good glycemic control and well-tolerated modern immunosuppressant therapy may be useful in improving prognosis of severe COVID-19 illness in patients with APS-1.
Association of maternal dietary patterns with child birth weight and size in India: Evidence from National Family Health Survey, 2005 to 2016
Authors: Brajesh Brajesh , Shekhar Chander
Published: January 2022

Background: Maternal dietary diversity during pregnancy is a major determinant of birth weight and birth size of infant. During pregnancy, mother diet is highly dependent on their topographical, cultural, and sociodemographic circumstances. Objective: The objective of the study was to assess the association between the maternal dietary intake with child birth weight and birth size along with the sociodemographic factors in India. Materials and Methods: The data for this study were drawn from the National Family Health Survey (NFHS), 2005 to 2006 and 2015 to 2016 held in India. Inferential statistical analysis Chi-square was built to test was used to examine the association between maternal dietary patterns, and logistic regression model was used to analyze the effect of mother’s dietary patterns on child birth weight and size by controlling the sociodemographic factors. Results: Mother’s daily intake of fish, meat, green leafy vegetables, and fruits was associated with higher birth weight or size and lower risk of intrauterine growth retardation. Women with ?2 dietary diversity categories had significantly higher proportion of low birth weight (LBW) and size of babies comparatively to those in the ?2 dietary diversity categories, there were lesser chance of LBW and small size of babies with women’s dietary diversity 3 (odds ranges from 1.09 to 1.44) or ?4 (odds ranges from 1.15 to 1.59). Furthermore, low birth order, mother’s underweight status, low maternal education, and wealth status significantly have positive association with the poor birth outcomes. Conclusion: The birth weight and size of newborns were found positively associated with the mother’s dietary intake. To meet the aim of maternal dietary diversity and to achieve the double bonus, the government should focus more on supplementation and food security programs during pregnancy that also include nutritional education as well as behavioral and social change interventions strategies.
РОЗВИТОК ТУРИСТИЧНО-РЕКРЕАЦІЙНОГО КОМПЛЕКСУ В УМОВАХ СТАЛОГО ЗРОСТАННЯ ЕКОНОМІКИ
Authors: Пригара Ольга , Брик Степан , Голубець Ірина
Published: January 2022

У науковій статті досліджено особливості розвитку туристично-рекреаційного комплексу в умовах сталого зростання економіки України. Встановлено, що туристично-рекреаційний комплекс – це один із ключових видів економічної діяльності в Україні, без якої не можливий сталий розвиток національної економіки. Пандемічні обмеження, спричинені COVID-19, негативно позначились на показниках розвитку туристично-рекреаційного комплексу України. Так, у 2020 році у порівнянні із попередніми роками, а особливо із 2019 роком, суттєво скоротились надходження від подорожей та туризму в національну економіку, і, як наслідок, знизилася частка надходжень від подорожей та туризму у ВВП України. Пандемічні обмеження негативно позначились на залученні капітальних інвестицій у розвиток туристичної діяльності в Україні, а також на стані діяльності колективних засобів розміщування. Тому, з метою зниження наслідків пандемічних обмежень на розвиток туристично-рекреаційного комплексу доцільно впроваджувати заходи мінімізації впливу пандемічних ризиків через спеціально розроблені програми підтримки видів економічної, зокрема туристично-рекреаційної діяльності, як на рівні держави, так і на рівні регіонів чи мікрорівні.
