Aim. To conduct the marketing research of the Ukrainian market in the segment of antihemorrhagic agents used in dentistry.Materials and methods. The study was performed using the structural analysis, logical and graphical methods, marketing analysis methods.Results. The state of the Ukrainian market of drugs of this group has been determined. The market structure has been revealed in the number of names, brands, in forms of production, manufacturers, composition. Despite the sufficient number of registered drugs at the market (26 positions), a rather small arsenal  of active substances (4) and dosage forms (3) can be observed. The market is characterized by a limited amount of drugs with a certain pharmacodynamics combining a rapid hemostatic effect, safety in use, the ability to suppress bacterial flora, and without the effect on healthy tissues. However, a positive moment should be noted: by the structure of manufacturer countries the market remains domestic (60 : 40).Conclusions. The Ukrainian pharmaceutical market is characterized by a sufficient assortment of hemostatic agents, but the use of these drugs in dentistry has its limitations. Dental doctors have certain problems with the occurrence of capillary bleeding and require a sufficient amount of effective and fastacting drugs for local application. Therefore, the search and creation of new drugs with a similar action at this stage remains a relevant scientific issue.
Revision and Conditional Inference for Abstract Dialectical Frameworks

Published: October 2021

For propositional beliefs, there are well-established connections between belief revision, defeasible conditionals and nonmonotonic inference. In argumentative contexts, such connections have not yet been investigated. On the one hand, the exact relationship between formal argumentation and nonmonotonic inference relations is a research topic that keeps on eluding researchers despite recently intensified efforts, whereas argumentative revision has been studied in numerous works during recent years. In this paper, we show that similar relationships between belief revision, defeasible conditionals and nonmonotonic inference hold in argumentative contexts as well. We first define revision operators for abstract dialectical frameworks, and use such revision operators to define dynamic conditionals by means of the Ramsey test. We show that such conditionals can be equivalently defined using a total preorder over three-valued interpretations, and study the inferential behaviour of the resulting conditional inference relations.
On Efficiently Explaining Graph-Based Classifiers
Authors: Huang Xuanxiang , Izza Yacine , Ignatiev Alexey , Marques-Silva Joao
Published: October 2021

Recent work has shown that not only decision trees (DTs) may not be interpretable but also proposed a polynomial-time algorithm for computing one PI-explanation of a DT.

This paper shows that for a wide range of classifiers, globally referred to as decision graphs, and which include decision trees and binary decision diagrams, but also their multi-valued variants, there exist polynomial-time algorithms for computing one PI-explanation. In addition, the paper also proposes a polynomial-time algorithm for computing one contrastive explanation. These novel algorithms build on explanation graphs (XpG's). XpG's denote a graph representation that enables both theoretical and practically efficient computation of explanations for decision graphs. Furthermore, the paper proposes a practically efficient solution for the enumeration of explanations, and studies the complexity of deciding whether a given feature is included in some explanation. For the concrete case of decision trees, the paper shows that the set of all contrastive explanations can be enumerated in polynomial time. Finally, the experimental results validate the practical applicability of the algorithms proposed in the paper on a wide range of publicly available benchmarks.
Safe Learning of Lifted Action Models
Authors: Juba Brendan , Le Hai S. , Stern Roni
Published: October 2021

Creating a domain model, even for classical, domain-independent planning, is a notoriously hard knowledge-engineering task. A natural approach to solve this problem is to learn a domain model from observations. However, model learning approaches frequently do not provide safety guarantees: the learned model may assume actions are applicable when they are not, and may incorrectly capture actions' effects. This may result in generating plans that will fail when executed. In some domains such failures are not acceptable, due to the cost of failure or inability to replan online after failure. In such settings, all learning must be done offline, based on some observations collected, e.g., by some other agents or a human. Through this learning, the task is to generate a plan that is guaranteed to be successful. This is called the model-free planning problem. Prior work proposed an algorithm for solving the model-free planning problem in classical planning. However, they were limited to learning grounded domains, and thus they could not scale. We generalize this prior work and propose the first safe model-free planning algorithm for lifted domains. We prove the correctness of our approach, and provide a statistical analysis showing that the number of trajectories needed to solve future problems with high probability is linear in the potential size of the domain model. We also present experiments on twelve IPC domains showing that our approach is able to learn the real action model in all cases with at most two trajectories.
Separating Data Examples by Description Logic Concepts with Restricted Signatures
Authors: Jung Jean Christoph , Lutz Carsten , Pulcini Hadrien , Wolter Frank
Published: October 2021

We study the separation of positive and negative data examples in terms of description logic concepts in the presence of an ontology. In contrast to previous work, we add a signature that specifies a subset of the symbols that can be used for separation, and we admit individual names in that signature. We consider weak and strong versions of the resulting problem that differ in how the negative examples are treated and we distinguish between separation with and without helper symbols. Within this framework, we compare the separating power of different languages and investigate the complexity of deciding separability. While weak separability is shown to be closely related to conservative extensions, strongly separating concepts coincide with Craig interpolants, for suitably defined encodings of the data and ontology. This enables us to transfer known results from those fields

to separability. Conversely, we obtain original results on separability that can be transferred backward. For example, rather surprisingly, conservative extensions and weak separability in ALCO are both 3ExpTime-complete.

Multicultural Education through Constructivist Learning Strategies
Authors: Saefudin Ahmad , Ro'fah Ro'fah , Sari Dyah Arum
Published: October 2021

The Madrasa as Islamic educational institutions has a crucial role in promoting multicultural education values ​​so that students avoid prejudice, suspicion, and intolerance. The Akidah Akhlak Teachers at MI Masalikil Huda 2 have a unique way to promote these values, namely through constructivism-based learning strategies. With a qualitative approach relying on the interview, observation, and documentation techniques, the researchers try to answer two important questions; how the teacher's strategy in introducing students to the values ​​of multicultural education and what approaches they use in the learning process in the classroom. Finally, this research concludes that teachers instill the values ​​of democracy, tolerance, equality or equality, brotherhood or kinship, and the value of unity in learning Akidah Akhlak. There are four constructivism strategies in the delivery of multicultural education, namely cooperative learning, conceptual achievement, exemplary, habituation, and role-playing. They also rely on historical approaches, gender perspective approaches, and aesthetic approaches. Thus, the claim that the madrasa is inconsistent in delivering Islamic religious material with a multicultural perspective is refuted by the findings of this research.

“NIMS” nasal mucoperiosteal flap for sublabial trans-sphenoidal surgical defect repair: A new technique under microscope
Authors: Alugolu Rajesh , Rangan Vasundhara , Ram Raghu , Saradhi M. Vijaya
Published: October 2021

Background:

CSF rhinorrhea is a known complication that may occur after cranial base surgery, especially the trans-sphenoidal approaches to sellar tumors. It may occur following both microscopic and endoscopic procedures. Over a period, the balance has tilted toward endoscopy due to development of pedicled Hadad flap. Microscopic trans-sphenoidal surgery (TSS) continues to be performed in our institute as well as many other centers across the world due to familiarity of technique and unavailability of endoscopic equipment. Despite the fairly widespread use of this surgery, literature is devoid of any description of a local mucosal flap for repair of the surgical defect in microscopic TSS.

Methods:

We herein described the procedure and our experience of harvesting such flap in 42 patients operated for pituitary adenomas in our department between September 2016 and February 2020, through microscopic sublabial TSS.

Results:

All 42 of the patients included in this study underwent excision of pituitary tumors (macroadenomas). Thirty-nine (n = 39) patients were undergoing 1st time surgery, while three (n = 3) of these patients were undergoing second surgery following an earlier trans nasal trans-sphenoidal route. None of our cases have reported CSF leak postoperatively.

Conclusion:

This study attempts to highlight to ardent/obligate microscopic surgeons that a local vascularized flap can be harvested for repair of skull base defect and prevent postoperative CSF leak in microscopic sublabial TSS.

Метод может быть использован в процессе алгебраического криптоанализа для оценки стойкости алгоритмов поточного шифрования.

The algebraic method of cryptanalysis, based on solving systems of equations over a finite field, is one of the modern methods that is widely used in the process of assessing the strength of a stream encryption algorithm. In practice, as part of the majority of stream encryption algorithms, Boolean functions are used as the main transformations. The algebraic immunity of this Boolean function is one of the main parameters determining the strength of the encryption algorithm. In the article, a method for determining the index of algebraic immunity of a Boolean function is proposed, and an algorithm for calculating this function is constructed. To determine the index of algebraic immunity of a Boolean function, the operation of calculating the rank of a specially constructed matrix is used. A number of examples are given for calculation of the algebraic immunity of a Boolean function and construction of annihilator functions. Also, the results of the experiments are shown, by the definition of the algebraic immunity of all balanced and unbalanced Boolean functions over a finite fieldn(1 n 6). The method may be used in the process of algebraic cryptanalysis in order to assess the strength of stream encryption algorithms.

The purpose of this study is to create information system for seismometric monitoring of the technical condition of hydroelectric dams. To achieve this, the authors of the article used modern methods and principles for designing software and technical systems. The methodological basis of this system is the engineeringseismometric method. The registered vibrations determine the dynamic and elastic characteristics of the structure. Analyzing their variations and taking into account the influence of factors of external influences, it is possible to estimate the technical condition of the structure. The authors provide a survey of seismometric monitoring systems for buildings and structures, defined main technical and functional requirements, which a monitoring system should provide. A model and a structure of the information system for seismometric monitoring of hydroelectric dams were developed using structural analysis technique. The paper describes the processes of collecting, processing, storing and analyzing data for seismic events recording and monitoring the technical condition. Based on the system model and the technology for seismometric monitoring data, automated systems for seismometric monitoring for the dams of Krasnoyarsk and Zeya hydroelectric stations were developed and put into operation. The systems provide registration of seismic events with an intensity of more than 2 points on the MSK64 scale on the dam and scheduled periodic recording of microseismic dam oscillations in the normal operation of equipment for monitoring the technical condition.

Published: October 2021

Описывается математическое моделирование газодинамических процессов, протекающих в основных функциональных частях импульсной аэродинамической установки. Осуществляется расчет локальных и интегральных параметров обтекания модели конуса, расположенной в рабочей части установки. Приводится качественное и количественное сравнение результатов математического и физического моделирования.

Purpose.The aim of this paper is the mathematical modelling of gasdynamic processes and the incoming airflow around the model fixed in the test chamber of the main functional elements of a pulsed aerodynamic facility. Methodology.Physical and mathematical modelling methods are jointly used for comprehensive description of the processes under study. The experimentally obtained results of drainage and balance measurements combined with visualization of the flow around the model using the shadow method are used to validate the numerical solution of the problem. System of unsteady Reynolds averaged NavierStokes (RANS) equations and SST turbulence model are used for mathematical description of the movement of working gas flow from prechamber through the nozzle to the test chamber where the body was fixed. Finite elements method implemented in Ansys Fluent computational complex is used for the numerical solution. Findings.Mathematical modelling of the flow around the cone model by the incoming flow with Mach numbers M 2...5 was carried out. The distribution fields of gasdynamic parameters (,P,T,M) over the entire internal volume of the pulsed aerodynamic facility (prechamber, axisymmetric nozzles set, test chamber) are obtained. The values of static pressure at the model surface and Mach number at nozzle exit are calculated for each velocity. Relative error between numerical calculation and experimental data is obtained to be of the order of 10 and 3, respectively. For flow structure near the model we obtain a qualitative agreement that the density distribution field is identical to the shadowgraph flow visualization pattern. Value.A numerical method for calculation of local and integral parameters of supersonic and hypersonic flow around models in test chamber of aerodynamic facility was implemented. Information about the gasdynamic flow parameters at the nozzle exit allowing the study of the flow around the model for the cases with more complex geometry using mathematical modelling based on the results of experiments.
The impact of the coronavirus pandemic on the dividend target payout ratio. The evidence from Hydrotor SA
Authors: Kowerski Mieczysław , Sowa Marcin
Published: October 2021

Lintner’s (1956) partial adjustment model identifies the company’s long-term dividend policy by setting a dividend target payout ratio and the speed of adjustment. And although the model has undergone various modifications and methods of estimation over more than 60 years, it is still a good tool for analyzing dividend decisions made by companies. The aim of the article is to show the usefulness of the Lintner model for analyzing changes in the company’s dividend policy during the pandemic turmoil. For the illustration, Hydrotor SA was chosen, which, the longest time at the Warsaw Stock Exchange, continuously pays dividends. The calculations showed that the situation in 2020 resulted in a revision of the company’s long-term dividend strategy, which resulted in a lowering of the dividend target payout ratio and a greater attention to the current situation (current net profits)—an increase in the speed of adjustment.
Investments in the cryptocurrency market or the commodity exchange. Which is more efficient?
Authors: Kozak Sylwester , Gajdek Seweryn
Published: October 2021

Cryptocurrencies have become an essential element of the global financial system, and in recent years also a frequent investment tool. The aim of the study is to check whether investments in cryptocurrencies are more effective than in commodities on commodity exchanges. The study was conducted based on the daily quotations of the analyzed instruments in 2011–2020. The investment efficiency level was estimated using Sharpe’s and Sortino’s indicators. The research results showed that, on average, over the entire period under study, investments in cryptocurrencies were burdened with the highest risk, but at the same time achieved the highest daily rates of return. As a result, they were much more effective investment tools than gold, silver and WTI. The advantage of cryptocurrencies could be due to the long-term persistence of ultra-low interest rates and the reduced attractiveness of investment in debt securities. Bitcoin and etherum with the largest shares in cryptocurrency market capitalization have proven to be the most effective investment tools.

Chất lượng nước (CLN) sông Hương được đánh giá sơ bộ qua so sánh các thông số quan trắc với quy định kỹ thuật Việt Nam về CLN mặt. Tiếp theo, CLN sông được đánh giá qua Chỉ số chất lượng nước (WQI). Phương pháp phân tích thành phần chính (PCA) được áp dụng cho dữ liệu CLN sông giai đoạn 2017–2020 để xác định trọng số (wi) của thông số CLN i trong tính toán WQI. Chỉ số chất lượng nước được tính từ cả trọng số và chỉ số phụ (qi). Các thông số được lựa chọn để tính WQI gồm (n = 11): pH, EC (độ dẫn điện), DO, TSS, BOD5, COD, N-NH4+, N-NO3–, P-PO43–, Fe (tổng sắt tan) và TC (tổng coliform). Các thông số đó được quan trắc ở 8–10 vị trí trong 4–5 đợt (tháng 2, 5, 8 và 11). Kết quả cho thấy, 95% các giá trị WQI nằm trong khoảng 90–100, ứng với CLN loại ‘tốt’ và ‘rất tốt’; chỉ 5% các giá trị WQI nằm trong khoảng 49–77 (chủ yếu vào tháng 11/2020), ứng với CLN loại ‘xấu’ đến ‘tốt’. Vào mùa mưa lũ, nồng độ TSS và Fe tăng lên, nồng độ DO giảm, dẫn đến làm giảm WQI. Chất lượng nước sông không khác nhau có ý nghĩa thống kê theo không gian/vị trí quan trắc (p > 0,05) với WQI trung vị 97–100 nhưng khác nhau theo thời gian: năm 2017 và 2019 có WQI trung vị (99) lớn hơn năm 2018 và 2020 (WQI trung vị 97) với p < 0,01.

Цель работы: В статье рассматривается применения риск-ориентированного подхода при проведении финансового мониторинга и контроля местного бюджета. Метод или методология проведения работы. Проведен статистический анализ изменений, происшедших в системе финансового мониторинга контроля органов местного самоуправления. Результаты. Одним из возможных вариантов упрощения непростой для многих государственных органов и органов местного самоуправления задачи по принятию нормативных правовых актов в сфере осуществления финансового мониторинга и контроля может стать разработка Типовых положений о различных видах финансового мониторинга и контроля. Во-первых, Типовые положения могут стать основой для принятия подзаконных актов – государственным органам и органам местного самоуправления не придется «придумывать велосипед», достаточно будет лишь адаптировать нормативную основу осуществления того или иного вида контроля к особенностям функционирования того или иного органа. Во-вторых, Типовые положения позволят унифицировать регулирование осуществления различных видов финансового мониторинга и контроля в субъектах Российской Федерации и муниципальных образованиях. Область применения результатов. Результаты проведенного исследования могут быть использованы при анализе и прогнозировании структурных изменений в системе финансового мониторинга и контроля. Выводы. Делается вывод, что модернизация системы мероприятий финансового мониторинга и контроля должна опираться на прогнозирование негативных последствий, передовой опыт отечественного и зарубежного правового регулирования, результаты общественного обсуждения проекта закона о финансовом мониторинге и контроле.
