The influence of edaphic factors on the vital state of large-flowered magnolia (Magnolia grandiflora L.). in the Nikitsky Botanical Gardens
Authors: Gerasimchuk V. N. , Novitsky M. L.
Published: November 2021

The most widespread magnolia on the Southern coast of the Crimea and, in particular, in the Arboretum of the Nikitsky Botanical Gardens is the evergreen Magnolia grandiflora L., introduced in 1817. Currently, 28 generative specimens of Magnolia grandiflora of different ages grow in the Arboretum, including garden forms with different vital state. There are very few data on the relation of this species to soil conditions. For this reason, we have studied the influence of edaphic factors on the vital state of Magnolia grandiflora growing in the Arboretum of the Nikitsky Botanical Gardens. A number of limiting edaphic factors have been identified, the main of which is the high skeletal structure of the soil. The humus reserves in the soil have a positive effect on the vital state of trees. A high level of agricultural technology is the main method of improving the vital state of Magnolia grandiflora .

Published: November 2021

The results of the study of drought resistance of 4 cultivars Prunus armeniaca Lam bred in the Nikitsky Botanical Gardens are presented. The dynamics of indicators of the water regime of leaves, the content of photosynthetic pigments and phenolic compounds in them has been studied. As a result of the research, information was obtained on the physiological and biochemical characteristics of apricot against the background of adaptation to stressful conditions created by moisture deficit during the summer drought on the Southern Coast of the Crimea. Significant differences were revealed in the ability to retain moisture during wilting, the ability to restore tissue turgor after critical dehydration, the concentration of chlorophylls and phenolic substances in the cultivars of different resistance to water stress. The promising drought-resistant genotypes 'Professor Smykov' and 'Kazachok' have been identified, demonstrating a relatively high level of water-retaining forces of leaf tissues and reparation of the leaf surface area.

Published: November 2021

Information about the peculiarities of the formation of storm emissions of macrophyte on the coast, at cape Martyan (the Southern coast of the Crimea) is presented. The studies were conducted from June 2019 to August 2020. Storm emissions on this part of the coast are formed with winds from the eastern (including north-eastern and south - eastern), southern and south-western directions and the corresponding direction of the waves. With north and west winds, the accumulated algae are carried back to the sea. Along the leveled coastal areas, storm emissions are distributed fairly evenly, without forming abundant accumulations. Stable zones accumulation of emissions are formed near the block heap, as well as at the bases of hydraulic structures. During one storm, cast ashore 40 kg to 7784 kg of phytomass. In total, 33061 kg of storm emissions were received on the shore during the year, which is about one percent of the annual production and a little more than two percent of the bottom vegetation reserves of the adjacent water area. The volume of storm emissions depends on the intensity of wave activity, the direction and strength of winds, on the morphology of the coast, as well as on seasonal phenomena in the life cycle of macrophytes.

A survey of medical university students was conducted (20 people, 45% worked with patients with coronavirus infection). We studied stress factors and the psychological effectiveness of the course medication intake of the "Restorative" herbal blend (oregano grass, thyme grass, blackberry leaf, echinacea leaf). The reception period is 20 days. The available stress factors were evaluated by a developed questionnaire, in which scaling was performed in the paradigm of the International Classification of Functioning. The psychological state before and after taking the herbal blend was assessed using the methods "Coping behavior in stressful situations", "Taylor's scale of anxiety manifestations", "Emotional burnout" by V. Boyko. The most significant challenges for respondents are caused by prolonged and intense psychoemotional loads, violations of the work and rest regime. After taking the herbal blend, mental resources increase, anxiety and depression decrease. The subjects begin to deal with stress productively, and not emotionally reacting. The emotional deficit, saving of mental resources, inadequate response to adverse factors are reduced, which indicates the general strengthening effect of the "Restorative" herbal blend not only on the body as a whole, but also on mental processes.

Published: November 2021

Smart farming is one of the keys for future agriculture because it is a management to use modern technology for increasing the quality and quantity of the agriculture. And because of the planet quality depend on the amount of water and the characteristics of soil, it is necessary to study the soil using the soil moisture sensor to investigate whether the soil is dry or wet, also to consider the challenges that could be faced in agricultural environment by maintain the soil and the planets irrigated without extra usage of water. In this paper, a prototype irrigation system uses Arduino Uno microcontroller which is programmed in C++ language to sense the degree of moisture by using soil moisture sensor. According to moisture sensor readings, when the moisture sensor above 1000, Arduino triggers to supply the water by using 5V mini water pump and stop when the soil moisture sensor reading reaches below 400. GSM technology enables the user to be notified in any changes happening in agricultural area by sending SMS (Short Message Service). Whenever the soil become wet or dry and the mini water pump switched on or off, a message delivered to user’s cellular phone indicating the condition of the soil and the action of water pump. In that capacity, this prototype will reduce the time for the user by monitoring remotely without going to his land, and also to reduce the usage of water by allow the water pump to flow the water for limited time until the moisture degree raise again.

ЗАКОННІСТЬ ТА ОБҐРУНТОВАНІСТЬ СУДОВОГО РІШЕННЯ ЯК ГАРАНТІЯ РЕАЛІЗАЦІЇ ЗАСАД СПРАВЕДЛИВОСТІ СУДОВОГО РОЗГЛЯДУ
Authors: Завальнюк І. В.
Published: November 2021

У статті досліджено конституційно-правові категорії законності та обґрунтова- ності судового рішення як гарантії реалізації засад справедливості судового розгляду в Україні. Наго- лошено, що вимоги, які пред’являються до судового рішення, служать конституційною гарантією вирішення проблеми в рамках закону, захисту прав і законних інтересів людини і громадянина, від- новлення порушеного права і законності, гарантією здійснення правосуддя, тобто однією з найваж- ливіших гарантій становлення правової держави. Зазначено, що тільки за умови дотримання судом усіх вимог, встановлених в законі щодо правомірності винесеного судового рішення, можна гово- рити про виконання конституційно закріплених завдань судочинства і правосуддя. Констатовано, що вимоги, які пред’являються до судового рішення, якщо зважати на їхню конституційно-правову суть призначення, визначаються рядом положень: система етичних, моральних засад, що характери- зують правосуб’єктність і судові рішення як її акти; цілі й завдання судочинства; функції, які вико- нують судові рішення. Визначено, що законність і обґрунтованість – це не тільки вимоги до судового рішення, а й основні його властивості. Зроблено висновок, що виконання судами всіх вимог закону, що пред’являються до судових рішень, є неодмінною умовою їх ефективності в справі захисту прав і охо- ронюваних законом інтересів громадян, інших суб’єктів, попередження правопорушень. Обґрунтовано, що під час здійснення правосуддя зазначені вимоги не можуть існувати окремо одне від одного. Зако- нодавець пов’язує ці поняття воєдино, а їх роздільне застосування є необхідним виключно в інтересах практики. Винесене судове рішення повинно відповідати нормам процесуального права, при наявності необхідних реквізитів, закріплених законодавством України. Визначено, що завданнями судочинства є правильний і своєчасний розгляд та вирішення справ з метою захисту порушених або оспорюваних прав, свобод і законних інтересів громадян, прав та інтересів України. Наголошено, що судове рішення можна вважати тим ідеалом, за допомогою якого здійснюється захист і відновлення порушених або оспорюваних прав вищевказаних суб’єктів. Наголошено, що сьогодні якість складених і оформлених судових рішень знаходиться на досить низькому рівні, оскільки у багатьох перевірених рішеннях суду знайдено орфографічні, пунктуаційні, граматичні, лексичні та стилістичні помилки. Доведено, що якість судового рішення визначається сукупністю істотних властивостей, що дозволяє говорити про рішення суду як про вольовий, індивідуально визначений процесуальний акт, прийнятий судом, що носить державний владний характер і виноситься в письмовій формі. Зроблено висновок, що в ідеалі справедливість і об’єктивність як вимоги до судового рішення повинні збігатися у своєму прояві, адже будь-яка об’єктивність має бути справедливою.
ІНСТИТУЦІЙНИЙ БАЛАНС У КРИМІНАЛЬНОМУ ПРОВАДЖЕННІ
Authors: Дуфенюк О. М.
Published: November 2021

У статті розглядаються концептуальні засади інституційного балансу у криміналь- ному провадженні. Мета статті та наукова новизна полягає в екстраполяції вчення про інституцій- ний баланс у сферу кримінального провадження з метою створення методологічного фундаменту для провадження подальших дискусій про реформи в системі кримінального провадження. Стаття скла- дається з двох частин. У першій частині розглянуто імплементацію концепції інституціоналізму та інституційного балансу у сферу кримінального провадження. Друга частина присвячена висвітленню змісту поняття «інституційного балансу» у кримінальному провадженні. Доведено, що проблематика інституціоналізму активно розробляється у сфері економіки, соці- альної сфери, управлінні та інших галузях наукового знання, проте на рівні кримінальної процесуаль- ної науки залишилася поза увагою і не отримала форми окремого вчення. Водночас підкреслено, що актуальність та важливість дослідження питання інституційного балансу детермінує значущість завдань кримінального провадження, висока потенційна можливість застосування специфічних захо- дів примусу та обмеження конституційних прав людини, зрештою й високі очікування суспільства до системи правоохоронних та судових органів сьогодні, коли наше суспільство переживає чергову «кризу справедливості». Інституційним балансом у кримінальному провадженні пропонується вважати нормативно врегу- льовану узгодженість функцій та повноважень різних органів державної влади з метою налагодження ефективної взаємодії між ними під час виконання завдань кримінального провадження. Інституцій- ний баланс можливий, коли є чіткий розподіл зон відповідальності між інституціями, гарантовано їх незалежність, відсутнє дублювання функцій, безпідставне втручання одних інституцій у сферу повно- важень інших або передача повноважень одними інституціями іншим. Наступні публікації авторки будуть присвячені питанням структури інституційного середовища, оцінці сучасного стану інституційної інфраструктури кримінального провадження та вивченню ризи- ків інституційного дисбалансу, зокрема практичних прикладів міжінституційних конфліктів.
ПРАВОВА ПРИРОДА ФІНАНСОВИХ ВІДНОСИН МІЖНАРОДНОГО ВАЛЮТНОГО ФОНДУ З КРАЇНАМИ-ЧЛЕНАМИ
Authors: Вайцеховська О. Р.
Published: November 2021

Статтю присвячено дослідженню механізмів фінансування Міжнародного валютного фонду. На підставі проаналізованої наукової літератури з даної проблематики висвітлено спектр діаметрально різних поглядів на правову природу фінансування МВФ, а саме механізм фінансування МВФ розглядається науковцями як: 1) кредит; 2) відсутність кредитних відносин, оскільки має місце купівля валюти; 3) міжнародний договір; 3) відсутність договірних відносин, оскільки міжнародна угода між МВФ і країною, якій надається фінансування, не укладається. Проаналізовано нормативно-правове підґрунтя та умови надання фінансової допомоги Фонду кра- їнам-членам. Проілюстровано організаційно-правові особливості процедури отримання валютних коштів на прикладі фінансування України, висвітлено основний зміст таких документів, як Лист про наміри та Меморандум про економічну та фінансову політику. Визначено, що механізми фінансування МВФ: 1) ані формально, ані структурно не належать до системи міжнародних договорів, а виступають особливим правовим механізмом у формі односто- ронніх рішень щодо надання фінансування країні-члену; 2) за змістом домовленостей не належать до кредитних договорів, а є купівлею-продажем відповідної валюти (але за функціональним призначенням подібні до кредитних договорів). Встановлено, що, незважаючи на відсутність юридично оформленого індивідуального кредитного договору між МФВ і країною-членом, практика відносин свідчить, що цей факт не зменшує ймовір- ність виконання відповідних зобов’язань з боку країн через такі чинники: 1) зобов’язання, що виплива- ють із механізмів фінансування, виконуються як такі, що випливають зі Статуту МВФ; 2) автори- тет МВФ як центральної інституції в міжнародному валютному правопорядку; 3) репутаційні ризики у випадку порушення країною умов механізму фінансування.

This paper presents the impact of fiber and wire mesh layers on the strength behavior of flat as well as folded fly ash-based geopolymer ferrocement panels. The behavior, including flexural strength, ductility, stiffness, and cracking patterns are observed. With an objective of decreasing CO2 emissions, the concrete utilizes wastes such as fly ash disposed by industrial sectors. Six panels (three flat and three folded) were cast utilizing fly ash dependent geopolymer mortar of size 1000mm x 400mm x 30mm. Heat curing in a temperature-controlled chamber maintaining 75○C to 80○C for 24 hours was done after 24 hours of resting period. The experimental results indicated that the flexural strength got enhanced by 33 percent by increasing the quantity of wire mesh layers, but the ductility got decreased by 30 percent for the flat panels; however, there was no noticeable impact in case of folded panels. The flexural strength of folded panels was found to be three times greater than that of flat panels. In addition, it is noticed that the behavior of fiber reinforced flat as well as folded panels of single layer mesh is stronger than double layer wire mesh panels with regard to cracking and ultimate load. The energy absorbed at failure was directly proportional to the volume of the reinforcement provided in the panels.

The using of magnesium alloys for industrial sheet metal part production has become increasingly common in recent years. This research aims to characterize the effects of the cutting-edge shapes of the punches on the blanking forces and the sheared edge qualities in the blanking/piercing operations of magnesium alloy sheets. Magnesium sheets (AM60 and AZ61) were produced by casting and rolling processes. AM60 and AZ61 Mg alloys produced by casting were rolled by using two different speeds, 2.5 m/min and 7.5 m/min. Material thickness was adjusted to three mm in the rolling process. Blanking tests were carried out on a die-set and hydraulic press by varying shaped punches. In the experimental studies, flat-ended, concave shaped, and 16° angled punches were used. A loadcell was fixed to the experimental setup to determine the blanking forces. The results showed that the AM60 alloy was more resistant to shearing than the AZ61. The lowest blanking force was obtained by use of the 16° angled punch. It was determined that the using of flat-ended punches for blanking operations was more convenient according to the usage purpose of the parts while all three punches can be used for piercing operations.

Haar’s theorem ensures a unique nontrivial regular Borel measure on a locally compact Hausdorff topological group, up to multiplication by a positive constant. In this article, we extend Haar’s theorem to the case of locally compact Hausdorff strongly topological gyrogroups. We simultaneously prove the existence and uniqueness of a Haar measure on a locally compact Hausdorff strongly topological gyrogroup, using the method of Steinlage. We then find a natural relationship between Haar measures on gyrogroups and on their related groups. As an application of this result, we study some properties of a convolution-like operation on the space of Haar integrable functions defined on a locally compact Hausdorff strongly topological gyrogroup
Resolutions of Convex Geometries
Authors: Cantone Domenico , Doignon Jean-Paul , Giarlotta Alfio , Watson Stephen
Published: November 2021

Convex geometries (Edelman and Jamison, 1985) are finite combinatorial structures dual to union-closed antimatroids or learning spaces.  We define an operation of resolution for convex geometries, which replaces each element of a base convex geometry by a fiber convex geometry.  Contrary to what happens for similar constructions–compounds of hypergraphs, as in Chein, Habib and Maurer (1981), and compositions of set systems, as in Möhring and Radermacher)–, resolutions of convex geometries always yield a convex geometry.  

We investigate resolutions of special convex geometries: ordinal and affine.  A resolution of ordinal convex geometries is again ordinal, but a resolution of affine convex geometries may fail to be affine.  A notion of primitivity, which generalize the corresponding notion for posets, arises from resolutions: a convex geometry is primitive if it is not a resolution of smaller ones.  We obtain a characterization of affine convex geometries that are primitive, and compute the number of primitive convex geometries on at most four elements.  Several open problems are listed.
Transversals and Bipancyclicity in Bipartite Graph Families
Authors: Bradshaw Peter
Published: November 2021

A bipartite graph is called bipancyclic if it contains cycles of every even length from four up to the number of vertices in the graph. A theorem of Schmeichel and Mitchem states that for $n \geqslant 4$, every balanced bipartite graph on $2n$ vertices in which each vertex in one color class has degree greater than $\frac{n}{2}$ and each vertex in the other color class has degree at least $\frac{n}{2}$ is bipancyclic. We prove a generalization of this theorem in the setting of graph transversals. Namely, we show that given a family $\mathcal{G}$ of $2n$ bipartite graphs on a common set $X$ of $2n$ vertices with a common balanced bipartition, if each graph of $\mathcal G$ has minimum degree greater than $\frac{n}{2}$ in one color class and minimum degree at least $\frac{n}{2}$ in the other color class, then there exists a cycle on $X$ of each even length $4 \leqslant \ell \leqslant 2n$ that uses at most one edge from each graph of $\mathcal G$. We also show that given a family $\mathcal G$ of $n$ bipartite graphs on a common set $X$ of $2n$ vertices meeting the same degree conditions, there exists a perfect matching on $X$ that uses exactly one edge from each graph of $\mathcal G$.
Single-Step Green Synthesis of Iron Nanoparticles in the Aqueous Phase for Catalytic Application in Degradation of Malachite Green
Authors: Rathore Ajay , Vijay Devra
Published: November 2021

The goal of the research was to devise a simple and environment-friendly approach to synthesize iron nanoparticles (FeNPs) and evaluate the catalytic activity of biosynthesized FeNPs for the degradation of the cationic dye Malachite Green (MG) in the presence of Peroxomonosulphate (PMS). Different instrumental approaches were used to characterize green produced FeNPs, and the results show that the NPs are spherical and 48 nm in size. Increasing the concentrations of nanoparticles (0.5 × 10-8 - 2.0 × 10-8 mol/dm3), Peroxomonosulphate (1.0 × 10-4 - 5.0 × 10-4 mol/dm3), dye (1.0 × 10-5 - 5.0 × 10-5 mol/dm3), pH (5), and high temperature (25-35 °C) enhanced the degradation kinetics of Pseudo-first-order kinetics were used to describe the degradation of MG in the FeNPs/PMS system, and activation parameters were derived. The maximum MG degrading efficiency for the FeNPs/PMS system was 88% in 60 minutes under optimum reaction conditions. The structure of intermediates formed by MG degradation by FeNPs/PMS was determined using UV-vis spectrum analysis. The application of synthesized FeNPs to improve Peroxomonosulphate oxidation potential for MG degradation is a unique, efficient, promising, and eco-friendly technology because it does not require any expensive reagents.

Published: November 2021

The rapid growth of the Chinese travel market has gained attention in the tourism industry. However, very few studies have been conducted to examine travel constraints that prevent Chinese outbound travelers from going somewhere quite accessible to their major destination from a multidestination
perspective. Drawing upon the leisure constraint model (LCM), this study explored Chinese independent tourists' perceived travel constraints in selecting second-tier destinations in their destination choice and analyzed the market segments. A self-administered survey was collected from 393
Chinese travelers who did not visit Gyeonggi Province close to Seoul during their travels in South Korea. Based on the findings, four distinct groups were formed. The findings provide important insights into destinations that desire to attract more Chinese independent travelers.

Authors: Walia Sandeep , Jasrotia Aruditya , Kour Parvinder , Choudhary Pooja
Published: November 2021

The debate pertaining to poverty alleviation and increased employment opportunities for tourism microentrepreneurship has recently emerged as an area of investigation in the spheres of academic research. The role of tourism microentrepreneurship in strengthening rural communities has
been researched by various tourism researchers and practitioners across the globe in the last few decades. The present study is aimed towards finding out the stakeholder's perception towards microentrepreneurship as a tool for conserving cultural, natural, and built heritage, particularly
in the state of Himachal Pradesh, India. To achieve the objectives of this study, a qualitative method has been adopted. The proposed method to investigate stakeholder perception is based on a two-step procedure. The first step identifies the sustainable practices available in the targeted
area, and in the second stage current entrepreneurial practices among the microentrepreneurs are investigated through interviews with the respondents to determine the accountability of those practices with sustainable heritage development in the study area. The findings of the study reflect
that there is a gap between the microentrepreneurship practices and the sustainable development in the study area. There is also a lack of policies and support from the side of governing bodies. Hence, the study puts forward the fact that despite several challenges, sustainable microentrepreneurship
can offer a potential solution to poverty alleviation in the Himalayan region of India. The economic benefits of sustainable micro-entrepreneurship are compelling, and its potential effects on the improvement of the overall lifestyle of stakeholders are equally promising.
Mind the Gap: Examining the Gap in International Passenger Expectations and Perceptions of Service Quality in Low-cost Carriers
Authors: Dsilva Jacinta , Balasubramanian Sreejith , Paris Cody Morris
Published: November 2021

Meeting or exceeding passengers' service quality expectations has become a critical factor for lowcost carriers (LCC). Still, only limited efforts have been made to date to investigate the differences (gap) in LCC passengers' expectations and perceptions. A comprehensive 25-item SERVQUAL
framework for LCC was first developed through an extensive literature review and insights obtained from exploratory interviews and focus groups with passengers and industry experts. Using survey data of LCC passengers, the validity and reliability of the framework were first established, and
then the differences in the expectations and perceptions were understood. The results indicate that none of the service quality attributes of LCCs have met, let alone exceeded, expectations, and the most significant gaps were found for "reliability" and "responsiveness" dimensions. With the
growing global demand for budget travel and new LCCs entering the market, the study provides timely insights for LCCs to narrow the expectation–perception gap and achieve competitive advantage.
Comparative Study on TCP SYN Flood DDoS Attack Detection: A Machine Learning Algorithm Based Approach
Authors: Sumathi S. , Rajesh R.
Published: November 2021

A most common attack on the internet network is a Distributed Denial of Service (DDoS) attack, which involves occupying computational resources and bandwidth to suppress services to potential clients. The attack scenario is to massively flood the packets. The attack is called a denial of service (DoS) if the attack originates from a single server, and a distributed denial of service (DDoS) if the attack originates from multiple servers. Control and mitigation of DDoS attacks have been a research goal for many scholars for over a decade, and they have achieved in delivering a few major DDoS detection and protection techniques. In the current state of internet use, how quickly and early a DDoS attack can be detected in broadcasting network transactions remains a key research goal. After the development of a machine learning algorithm, many potential methods of DDoS attack detection have been developed. The work presents the results of various experiments carried out using data mining and machine learning algorithms as well as a combination of these algorithms on the commonly available dataset named CAIDA for TCP SYN flood attack detection. Also, this work analysis the various performance metrics such as false positive rate, precision, recall, F-measure and receiver operating characteristic (ROC) using various machine learning algorithm. One-R(OR) with an ideal FPR value of 0.05 and recall value of 0.95,decision stump(DS) with an ideal precision value of o.93,PART with an excellent F-measure value of 0.91 are some of the performance metric values while performing TCP SYN flood attack detection.

In practice, the flexible functionality of IoT platforms often leads to additional costs for software enhancement of existing and connection of new units, in particular digital twins. The paper proposes a technological solution for the implementation of a digital twin of the ventilation process in the IoT control loop of heating, ventilation and air conditioning (HVAC) systems for buildings and industrial facilities. The implementation and execution of the digital twin in the form of a dynamic simulation model in the object-oriented modelling language Modelica in the OpenModelica environment is considered. The IoT platform InfluxData, based on the TICK stack, is considered as an example of an integration environment. It is a horizontally-oriented IoT platform that contains the mechanism for collecting data from devices and the InfluxDB time-series database for storing metrics. To integrate simulation models on Modelica with InfluxDB, an OMPython server is proposed. In this case, the integration scripts are executed in the Python language, which as a result extends the traditional capabilities of the IoT platform significantly to the level of a digitally twinned control system. This HVAC control involves adapting control loops by taking into account the dynamics of the air distribution process over the ventilation network, evaluating and compensating for process inertia.

This article is a continuation of the article published in Journal of Applied Informatics nо.1 in 2019 [1]. In it, the problems of computer design of routes of various linear structures (new and reconstructed railways and highways, pipelines for various purposes, canals, etc.) are considered from a unified standpoint, as problems of approximating a sequence of points on plane of a smooth curve consisting of elements of a given type, i.e. spline. The fundamental difference from other approximation problems considered in the theory of splines and its applications is that the boundaries of the elements of the spline and even their number are unknown. Therefore, a two-stage scheme for finding a solution has been proposed. At the first stage, the number of spline elements and their parameters are determined using dynamic programming. For some tasks, this stage is the only one. In more complex cases, the result of the first stage is used as an initial approximation to optimize the spline parameters using nonlinear programming. Another complicating factor is the presence of numerous restrictions on the spline parameters, which take into account design standards and conditions for the construction and subsequent operation of the structure. The article discusses the features of mathematical models of the corresponding design problems. For a spline consisting of arcs of circles, mated by line segments, used in the design of the longitudinal profile of both new and reconstructed railways and highways and pipelines, a mathematical model is built and a new algorithm for solving a nonlinear programming problem is proposed, taking into account the structural features of the constraint system. In contrast to standard nonlinear programming algorithms, a basis is constructed in the zero-space of the matrix of active constraints and its modification is used when the set of active constraints changes. At the same time, to find the direction of descent at each iteration, no solution of auxiliary systems of equations is required at all. Two options for organizing the iterative optimization process are considered: descent through groups of variables in the presence of sections for independent construction of the descent direction and the traditional change of all variables in one iteration. Experimentally, no significant advantage of one of these options has been revealed.

Preventing and neutralize dangerous situations tasks are relevant in the operation of complex technological objects. Complex technological objects present, in particular, in the support city systems (heat, water, energy, gas supply systems), at large industrial, mining, or processing enterprises. The development of dangerous situations at such facilities can lead to undesirable or even catastrophic consequences. The decision-making process to neutralize (prevent) an emerging dangerous situation is aimed at finding an action program that should transfer the current emergency situation into a target, standard situation. The article examines the possibility of implementing a case-based reasoning method for retrieving a solution using a neural network in order to prevent and neutralize dangerous situations at a complex technological object of city infrastructure. The authors consider the situation as a set of elements states of a complex object and the relationships between elements. To solve the tasks, the work examines two neural network architectures: a model that builds upon the multilayer perceptron and the "comparator - adder" architecture.Experiments have shown that the proposed neural network architecture "comparator - adder" showed higher accuracy than the multilayer perceptron for the considered tasks of comparing situations. The obtained result continues the well-known research in the integration of machine learning methods and methods of knowledge-based systems field. It serves as the basis for the further development of decision inference hybrid models for intelligent control of complex objects.
Psychological characteristics of the types of the experience of loneliness functional orientation
Authors: BEDAN Victoria
Published: November 2021

The article is devoted to the study of the "ego function" features of persons with different functional loneliness orientations. It discusses the views of scientists on the definition of the concepts of loneliness, and ideas about the functions of the ego, are included in the framework of the human model of personality by G. Ammon. The results of an empirical study aimed at determining the features of self-functions of individuals with different functional orientations of loneliness are stated. The bonds between the indicators of ego functions such as aggression, anxiety, internal and external selflimitations, narcissism, sexuality; and the types of functional loneliness orientation are established. Groups of creative, adaptive and self-destructive experiences of loneliness are defined. It has been established that groups of individuals with a different loneliness experience are distinguished by the specifics of the manifestation of ego functions (constructive, destructive, deficit). A descriptive characteristic of the ego-functional profiles of individuals with different experience types of loneliness orientation are presented, and their psychological portraits are compiled. It has been proven that people having creative types of loneliness experiences are inherently more sociable, empathetic, open, able to constructively overcome difficulties and interpersonal conflicts, have higher self-esteem, are more ambitious, realistic in their perception of themselves and others, emotionally and spiritually mature, and able to express feelings and emotional experiences. Persons with an adaptive type of loneliness experience are characterized by control of interpersonal distance, rational use of available resources, difficulties in setting and upholding personally significant goals, inconsistency of emotional experience, instability concerning oneself, emotional depreciation of important events and significant relationships, blocking activities; and feelings of fatigue, boredom and emotional emptiness. Persons with a self-destructive type of loneliness experience are characterized by between the person’s inner world and his social environment, resulting in increased mental stress, fear of the future, anxiety, uncertainty, dissatisfaction with life.
