Evaluation of quality level in managing the development of industrial enterprises

The research focuses on the substantiation of theoretical aspects and practical support for assessing the quality level of managing enterprises development taking into account the influence of the external and internal environment. The conceptual apparatus for estimation of quality development of enterprise management was refined, which makes it possible to determine reasonably the level of management according to the generally known elements (economic, social and ecological) that are proposed to be supplemented with an energy component. A new conceptual approach to the procedure of evaluation of the quality of development management by levels, the stages of which are proposed to expand by: the formation of the database by levels of management (state, regional), choice and evaluation of indicators by components of development and spheres of activity, development of the tools for management improvement. The integrated indicator has been proposed, which differs from the existing ones by the fact that it estimates the quality of development management, rather than the development level. In contrast to the previously proposed ones, the integrated indicator takes into account the influence of external environment by the components of development and of the internal environment – by the areas of activity for each component. That is why it has practical significance, since it allows performing monitoring and detecting the negative influence of management on the enterprise development. Taking coke plants as an example, the structures of the indicators that characterize the management quality were determined. A large number of indicators were reduced by the method of expert assessments, which increases the validity of the choice. Indicator estimates were constructed solely based on relative indicators (indices), which improves consistency. Using the integrated method, the estimation of the indicators by individual components and on the whole was performed. The scale for evaluation of the quality level of enterprise development management was constructed using the Harrington function. The new approach to assessing the quality of the enterprise development management and a complex of mathematical support will lead to the uniform economic, social, environmental and energy development of enterprises.Роботу присвячено обґрунтуванню теоретичних аспектiв та практичного забезпечення оцiнки якiсного рiвня управлiння розвитком пiдприємств з урахуванням впливу зовнiшнього та внутрiшнього середовища. Уточнено понятiйний апарат щодо оцiнки якiсного розвитку управлiння пiдприємствами, який дозволяє обґрунтовано визначати рiвень управлiння за загальновiдомими складовими (економiчної, соцiальної та екологiчної), до яких запропоновано додати енергетичну складову. Побудовано новий концептуальний пiдхiд до процедури оцiнки якостi управлiння розвитком за рiвнями, етапи якої запропоновано розширити за: формуванням бази даних за рiвнями управлiння (державний, регiональний), вибiр та оцiнка iндикаторiв за складовими розвитку та сферами дiяльностi, розробка iнструментiв щодо покращення управлiння. Запропоновано iнтегральний показника, який вiдрiзняється вiд iснуючих тим, що оцiнює якiсть управлiння розвитком, а не рiвень розвитку. На вiдмiну вiд запропонованих ранiше iнтегральний показник враховує вплив зовнiшнього середовища за складовими розвитку та внутрiшнього – за сферами дiяльностi по кожнiй складовiй. Тому, має практичну значимiсть, оскiльки стає можливим проводити монiторинг та виявляти негативний вплив управлiння на розвиток пiдприємства. На прикладi коксохiмiчних пiдприємств визначено склад iндикаторiв, якi характеризують якiсть управлiння. Велику кiлькiсть iндикаторiв скорочено за допомогою методу експертних оцiнок, що пiдвищує обґрунтованiсть вибору. Iндикаторнi оцiнки побудовано виключно за вiдносними показниками (iндексами), що покращує узгодженiсть. За iнтегральним методом проведена оцiнка iндикаторiв за окремими складовими та у цiлому. За функцiєю Харрiнгтону побудовано шкалу оцiнки якiсного рiвня управлiння розвитком пiдприємств. Новий пiдхiд щодо оцiнки якостi управлiння розвитком пiдприємств та комплекс математичного забезпечення приведе до рiвномiрного економiчного, соцiального, екологiчного i енергетичного розвитку пiдприємств

Effect of friction deformation on the structure and properties of a metastable austenitic chromium-nickel steel

The effect of surface friction deformation on the phase composition, structure, and strength properties of a ribbon produced from a chromium-nickel steel with metastable austenite is studied. It is shown that friction processing intensifies the γ-α transformation, creating favorable conditions for the formation of a highly dispersed structure in a thin surface layer and, thus, increasing the microhardness, the elastic limit, the fatigue stability, and the Bauschinger effect. © 2013 Pleiades Publishing, Ltd

ω-граничнi множини для iмпульсно-збуреного параболiчного рiвняння в просторi неперервних функцiй

We consider an important class of disturbed infinite-dimensional systems provided by evolutionary equations with impulsive effects. An impulsive dynamical system acting in the phase space H is a hybrid system described by an evolutionary equation together with impulsive disturbances which, in turn, are characterized by a closed set M ⊂ H (impulsive set) and a mapping I: M -> H (impulsive mapping). A solution of such a system, by definition, is a left-continuous function y satisfying evolutionary equation for all times t for which y(t) \notin M and jumping to a new state I(y(t)) at all times t for which y(t) reaches M. The main problem in the study of qualitative behavior of impulsive dynamical systems by classical methods is that solutions usually do not depend continuously on initial data. A number of examples illustrate already in the finite-dimensional case that new complex scenarios of possible limit behaviors of impulsive trajectories can occur, which are fundamentally impossible in the non-impulsive case. Results concerning attracting sets for infinite-dimensional impulsive systems have appeared only a few years ago. But all those results concern the limit behavior of impulsive semiflows in Hilbert space and the presence of scalar product played crucial role in those construction. In this paper we want to investigate ω-limit attracting sets for impulsive-disturbed parabolic system in the sup-norm of Banach space of continuous functions. Pages of the article in the issue: 42 - 48 Language of the article: UkrainianВ роботi розглядається iмпульсно-збурена нескiнченновимiрна задача, яка складається з параболiчного рiвняння, розв’язки якого зазнають iмпульсного збурення при досягненнi iнтегральним функцiоналом певного порогового значення. Доведено, що при певних умовах на коефiцiєнти така задача в фазовому просторi неперервних функцiй породжує iмпульсну динамiчну систему, кожна траєкторiя якої в sup-нормi притягується до компактної ω-граничної множини

The influence of reflexive educational environment on students’ reflection development in the process of social adaptation

The topicality of the research is caused by the necessity to overcome contradictions between the traditional environment of educational institutions and the socialization of future graduates related to their mental world creation, to finding their identity in terms of civilization change and the rapid development of digital technologies. The aim of the study lies in defining the additional functions of the reflexive educational environment and its influence in the formation of students’ reflexive abilities and their understanding of the relationship between reflection and adaptation process in society. The leading method to investigate this problem (issue) is the reflexive method, including introspection, self-analysis, existential techniques of ‘self-exploration’, a dialogical communicative technique that allowed identifying, through content analysis of reflexive and analytical essays of students, the types of adaptive orientations (and the reflexive repertoires based on them) from which, as they integrate, a reflexive personality style is developed. It is established that the reflexive repertoires used in the process of self-identification correspond to the four adaptive attitudes of the person: homeostatic, hedonistic, rationalistic and pragmatic. Social adaptation is manifested in a conscious change in behavior and one’s own life support system, in creating a new environment of social existence, and is accompanied by a transformation of consciousness and self-awareness. In this case, reflection is the main means of these changes and the integration of reflexive repertoires and of formed reflection levels (narrative, dialogical, cognitive and axiological) are the factors influencing the outcome of social adaptation. The results of the research are aimed at solving the problem of creating a reflexive educational environment for students’ personal development and at choosing effective ways and mechanisms for their adaptation and self-realization in society. The materials of the study can prove useful both for theoretical research of reflexive thinking development in a specially created educational environment and for the teaching activities, including a foreign language.Keywords: reflexive educational environment, reflexive orientation, reflexive repertoires, social adaptation

Evaluation of grain yield performance and its stability in various spring barley accessions under condition of different agroclimatic zones of Ukraine

Two extremely urgent problems of biological and agronomic research nowadays are ensuring an optimal balance between usage of natural resources to meet rapidly growing needs for food production and preservation of biodiversity. It is also important to extend the genetic diversity of the main crop varieties in agroecosystems. At the same time, modern varieties should be characterized by a combination of high yield and preserving yield stability under variable conditions. Solving the outlined tasks requires comprehensive research and involvement in breeding process of the genetical diversity concentrated in genebanks of the world. Barley (Hordeum vulgare L.) is one of the most important crops that satisfy the various needs of humanity. In respect to this, in 2020–2022, a multi-environment trial was conducted in three agroclimatic zones of Ukraine (Forest-Steppe, Polissia, and Northern Steppe). We studied 44 spring barley collection accessions of different ecological and geographical origin, different subspecies and groups of botanical varieties which were obtained from the National Center for Plant Genetic Resources of Ukraine. Statistical indices (Hom, Sc) and graphical models (GGE biplot, AMMI) were used to interpret the yield performance and its stability. Both individual ecological sites in different years and combinations of different sites and years of trials were characterized for productivity, discriminating power and representativeness. The environments differed quite strongly among themselves in terms of these indicators. It was established that most of the genotypes were characterized by higher adaptability to individual environmental conditions (stability in different years), compared to adaptability for all agroclimatic zones (wide adaptation). A strong cross-over genotype by environment interaction was found for most studied accessions. Nevertheless, both genotypes with very high stability in only one agroclimatic zone (Amil (UKR), Gateway (CAN)) and genotypes with a combination of high adaptability to one or two ecological niches and relatively higher wide adaptability (Stymul (UKR), Ly-1064 (UKR), Rannij (KAZ), Shedevr (UKR), and Arthur (CZE)) were identified. There were also the accessions which did not show maximum performance in the individual sites, but had relatively higher wide adaptability (Ly-1059 (UKR), Ly-1120 (UKR), Diantus (UKR), and Danielle (CZE)). In general, the naked barley genotypes were inferior to the covered ones in terms of yield potential and wide adaptability, but at the same time, some of them (CDC ExPlus (CAN), CDC Gainer (CAN), and Roseland (CAN)), accordingly to the statistical indicators, had increased stability in certain ecological sites. Among naked barley accessions relatively better wide adaptability according to the graphical analysis was found in the accession CDC McGwire (CAN), and by the statistical parameters CDC ExPlus (CAN) was better than standard. The peculiarities of yield manifestation and its variability in different spring barley genotypes in the multi-environment trial revealed in this study will contribute to the complementation and deepening of existing data in terms of the genotype by environment interaction. Our results can be used in further studies for developing spring barley variety models both with specific and wide adaptation under conditions of different agroclimatic zones of Ukraine. The disitnguished accessions of different origin and botanical affiliation are recommended for creating a new breeding material with the aim of simultaneously increasing yield potential and stability, as well as widening the genetic basis of spring barley varieties

Effect of superabsorbent on soil moisture, productivity and some physiological and biochemical characteristics of basil

Received: February 8th, 2021 ; Accepted: May 5th, 2021 ; Published: May 14th, 2021 ; Correspondence: [email protected] study was carried out in 2019–2020, in the conditions of the Right-Bank ForestSteppe of Ukraine. The results on the influence of absorbents in gel and powder forms on the productivity of basil plants (Ocimum basilicum L.) are presented. For research were used field, laboratory, statistical and calculation-analytical methods. Absorbent in the form of a gel was used while transplanting: dip the roots of the plant in the solution and then transplant in the field. Absorbent in the form of a powder - 5 kg ha-1 , application of the absorbent into the soil layer 20–25 cm-1 . Absorbents contributed to a slight decrease of sugar content (-0.86–2.68% in the cultivar of Badioryi, -1.48–2.35% in the cultivar of Rutan), significantly decrease ascorbic acid (-8.6–20.1%) and content of the essential oil (8.0–19.4%) and indirectly increased essential oil yield by increasing fresh weight yield in both varieties. The activity of APX, CAT, SOD, tended to decrease in all variants of the experiment, regardless of the form of the absorbent. APX (-12.8–35.1%), CAT (-10.9–22.0%), SOD (-11.9–17.0%). Higher yields were observed in the version with the introduction of the absorbent in the form of a gel. Thus, the yield of the cultivars of Badioryi and Rutan exceeded the control by 52.67 and 50.05%, in accordance. The productivity of basil is increased with the use of superabsorbent polymers. This practice can be recommended to agricultural producers who grow vegetables, in particular, basil in areas of unstable or insufficient moisture

Nash equilibrium design in the interaction model of entities in the customs service system

The urgency of the analyzed issue is due to the importance of the use of economic-mathematical tools in the course of modeling the interaction of the entities in the customs service system that is necessary for the development of foreign economic activity (FEA) of any state. The purpose of the article is to identify effective strategies for the interaction between the participants of foreign trade activities with customs brokers. The leading method to the study of this issue is economic-mathematical modeling, allowing studying the process of making decisions while choosing the strategy of cooperation between the customs broker and his client. Results: the article suggests the mathematical model to optimize the management mechanisms of interaction between enterprises, engaged in foreign trade, and customs dealers. The data of this article may be useful in modeling interaction of the entities in the customs service system using the methods of game theory. The model of “customer - customs broker” is implemented as a bimatrix game. Assuming the noncooperativegame the authors solve the problem of finding Nash equilibrium in mixed strategies. © 2016 Fedorenko et al

ПЕРЕДІСТОРІЯ СТАНОВЛЕННЯ СУДОВОЇ ЕКСПЕРТИЗИ ОБ’ЄКТІВ ПРАВА ІНТЕЛЕКТУАЛЬНОЇ ВЛАСНОСТІ В КОНТЕКСТІ ГЕНЕЗИСУ СУДОВО-ЕКСПЕРТНОЇ ДІЯЛЬНОСТІ В УКРАЇНІ (ВІД КИЇВСЬКОГО КНЯЗІВСТВА ДО ПЕРШОЇ СВІТОВОЇ ВІЙНИ) (оглядова стаття)

Preconditions for emergence of forensic intellectual property analysis in Ukraine and abroad in the period from the 10th to the beginning of 20th century in the context of forensic science genesis are comprehensively analyzed in the article. The following sources of court proceedings of the Kyivan Principality (Russia) Epoch and the so-called “Dark ages” (in the 12th/14th centuries), as “Russkaya Pravda”, treaties of appanage princes with grand princes and between each other, charters and letters patent of princes, sudebniky, etc., along with the Statutes of Lithuania (16th century) and others are considered. It is argued that emergence of forensic science in Europe was linked to origin and nature of evidence in court proceedings. Forensic experts are involved when their findings become legitimate evidence for court in criminal and civil proceedings. It is emphasized that for the first time the procedural status of a forensic expert as the “third party expert” is regulated in the Statute of Criminal Procedure of the Russian Empire of 1864 (Articles 112, 690, 691, 692, 698, etc.). It is noted that the establishment of forensic activities in the field of intellectual property was preceded by legitimization of intellectual property rights in Austria-Hungary, England, Spain, the Netherlands, Germany, Russia, the USA, France in the 18th century, as well as the establishment of administrative and judicial mechanisms for its protection. At the same time, the practice of involving experts in consideration of copyright disputes over scientific, literary and artistic works, inventions, etc., was uncommon in the 19th century. In 1913, offices of forensic science under the prosecutors of the Kyiv and Odessa Judicial Chambers, which contributed to institutionalization of forensic activities and professionalism of forensic experts were established. These circumstances created conditions for initiation of forensic intellectual properrty analysis. However, the First World War pushed the litigation over the right to intellectual property to the background.В публикации комплексно исследованы предпосылки зарождения судебной экспертизы объектов права интеллектуальной собственности в Украине и за рубежом в контексте генезиса судебно-экспертной деятельности с X до начала XX вв. Проанализированы такие источники судопроизводства эпохи Киевского княжества (Руси) и так называемых тёмных веков (XII–XIV), как «Русская Правда», договоры удельных князей с великими князьями и между собою, уставные и жаловальные грамоты князей, судебники и т. п., а также Литовские статуты (XVI). Обосновано положение о том, что появление судебной экспертизы в Европе связано с происхождением и характером доказательств в судопроизводстве. Необходимость в судебных экспертах возникла тогда, когда их выводы стали легитимными доказательствами для суда в уголовных и гражданских процессах. Подчёркнуто, что впервые процессуальный статус судебного эксперта как сведущего человека нормирован в Уставе уголовного судопроизводства Российской империи 1864 г. (ст. 112, 690– 692, 698 и др.). Отмечено, что учреждению судебно-экспертной деятельности в сфере интеллектуальной собственности предшествовала легитимизация права на объекты интеллектуальной собственности в Австро-Венгрии, Англии, Испании, Нидерландах, России, США, Франции в XVIII в., а также учреждение административных и судебных механизмов её защиты. Вместе с тем, практика привлечения сведущих людей к рассмотрению споров об авторских правах на научные, литературные и художественные произведения, изобретения и т. п. в XIX в. была редким явлением. В 1913 году в Украине созданы кабинеты научно-судебной экспертизы (НСЭ) при прокурорах Киевской и Одесской судебных палат, что способствовало институционализации судебно-экспертной деятельнообстоятельства создали предпосылки для учреждения судебной экспертизы в сфере интеллектуальной собственности, но Первая мировая война отодвинула судебные споры о праве интеллектуальной собственности на второй план.У публікації комплексно досліджено передумови започаткування судової експертизи об’єктів права інтелектуальної власності в Україні та за кордоном від X до початку XX ст. в контексті генезису судово-експертної діяльності. Проаналізовано джерела судочинства часів Київського князівства (Русі) і так званих темних століть (XII–XIV): «Руська Правда», договори удільних князів з великими князями й між собою, уставні й дарувальні грамоти князів, судебники та ін., а також Литовські статути (XVI). Обґрунтовано, що поява судової експертизи в Європі пов’язана з походженням і характером доказів у судочинстві. Необхідність у судових експертах виникла тоді, коли їхніх висновків (як легітимних доказів у кримінальному та цивільному процесах) потребував суд. Підкреслено, що вперше процесуальний статус судового експерта як обізнаної людини унормовано у Статуті кримінального судочинства Російської імперії 1864 р. (ст. 112, 690–692, 698 та ін.). Зазначено, що утвердженню судово-експертної діяльності в царині інтелектуальної власності передували легітимізація права на об’єкти інтелектуальної власності в Австро-Угорщині, Англії, Іспанії, Нідерландах, Німеччині, Росії, США, Франції у XVIII ст., а також затвердження адміністративних і судових механізмів її захисту. Водночас у XIX ст. була малопоширеною практика залучення обізнаних людей до розгляду спорів про авторські права на наукові, літературні й мистецькі твори, винаходи та ін. 1913 р. в Україні створено кабінети науково-судової експертизи при прокурорах Київської й Одеської судових палат, що сприяло інституціоналізації судово-експертної діяльності та професіоналізації діяльності судових експертів. Ці обставини створили умови для становлення судової експертизи у сфері інтелектуальної власності. Проте, Перша світова війна відсунула судові спори щодо прав на об’єкти інтелектуальної власності на другий план

Double difiusion in Ar-N2 Binary gas system at the constant value of temperature gradient

An experimental study of the diffusion-gravitational convection transition boundary in an Ar-N2 binary system at different pressures and a constant temperature gradient is performed. It is shown that the diflusion is replaced by the gravitational convection at a pressure p 0:5 MPa. In terms of the stability theory, a perturbation boundary line is determined, dividing the Rayleigh numbers plane into the regions of the diflusion and the convective mass transfer. The experimental data agree well with the theoretical values

Состояние перекисного окисления липидов при различных схемах лечения острого инфекционного миокардита у детей

Изучены динамика интенсивности процессов перекисного окисления липидов и изменение состояния антиоксидантной защиты при различных схемах лечения острого инфекционного миокардита у детей. Установлено, что оксидативный статус при остром инфекционном миокардите характеризуется активацией перекисного окисления липидов при достаточном уровне антиоксидантной защиты, а при тяжелом течении — углублением оксидативного стресса и угнетением активности антиоксидантной защиты. Анализ эффективности проведенной комплексной терапии острого инфекционного миокардита у детей показал статистически достоверное преимущество предложенного комплекса лечения с включением в стандартную терапию препаратов антигипоксического и антиоксидантного действия.Among the factors of nonspecific protection affecting the onset and course of acute infectious myocarditis (АІМ), the state of the system of lipid peroxidation is important, which, on the one hand, is an important part of the mechanisms of adaptation of the organism, and, on the other hand, is in a position lead to significant violations of the function of other protective systems. Excessive levels of intermediate and end-products of lipids peroxidation become toxic to the cells of most organs and are one of the mechanisms for the development of a false cycle of pathological processes in the development of myocarditis. The aim of the study was to study the dynamics of the intensity of lipid peroxidation and changes in the state of antioxidant protection in different regimens of treatment of AIM in children. The indexes of lipid peroxidation were studied in this work, which was judged by the concentration in the serum of the intermediate product of lipids peroxidation — diene conjugates and terminal — malonic dialdehyde in children with AIM. The state of antioxidant protection was evaluated by studying the activity of enzyme factors — superoxide dismutase and catalase in serum of sick children. The study cohort included 89 children with AIM. Depending on the treatment regimen, the children were divided into four groups: the control group included 21 patients who received standard therapy. 1st group consisted of 23 children, who along with the standard treatment were prescribed antihypoxic drug; in the 2nd group 22 patients received standard treatment in combination with an antioxidant drug; in the 3rd group 23 children received standard therapy in combination with antihypoxic and antioxidant drugs. It has been established that the oxidative status in acute infectious myocarditis is characterized by activation of lipid peroxidation at a sufficient level of antioxidant protection, and in severe course — by deepening of oxidative stress and inhibition of antioxidant protection activity. The analysis of the effectiveness of the complex therapy of acute infectious myocarditis in children showed a statistically significant advantage of the proposed treatment package with the inclusion in standard therapy of antihypoxic and antioxidant drugs
