Authors: Veremchuk Lyudmila V. , Vitkina Tatyana I. , Mineeva Elena E. , Kondratyeva Elena V.
Published: July 2023

Objective — To identify criteria for contrasting meteorological changes affecting the temporal dynamics of the immune response in individuals with bronchopulmonary pathology in the maritime monsoon climate of Vladivostok. Methods — We examined 178 patients with stable chronic obstructive pulmonary disease (COPD) of mild and moderate severity, 212 patients with controlled bronchial asthma (BA) and 60 apparently healthy volunteers. We assessed the cumulative response of the components of adaptive and innate immune systems to the effects of day-to-day variability in temperature, air pressure and humidity, wind speed and direction, and precipitation relative to the day of the patient’s medical examination ± 2 days. The response of the immune system was measured by an integral indicator calculated as the ratio of the sum of statistically significant correlations (p<0.05) to the total sum of correlation matrix elements. Results — The short-term compensatory severity and activity of the immune response to the weather in healthy people (∑D%=2.56; ∑r=117) was almost twice as high as the similar response in patients with COPD (∑D%=1.28; ∑r=72) or BA (∑D%=1.35; ∑r=69). The immune response of apparently healthy subjects to the action of specific meteorological factors on the day of medical examination was reduced by 40%, compared with the short-term response (±2 days) in patients with COPD, but the difference was not significant. The values of the criteria for the day-to-day contrast of influencing meteorological factors in apparently healthy patients were reduced. Conclusion — The urban population in maritime monsoon climate exhibited weak and moderate weather-induced immune system responses. Wind regime, humidity and precipitation had a pronounced effect on the immune system. In patients with COPD and BA, the maximum pathogenic response of the immune system to the impact of climatic factors was observed within ±1 day.
Excentrycy Włodzimierza Kowalewskiego: powrót staromodnej narracji
Authors:   Uniwersytet Pedagogiczny w Krakowie, Latawiec Krystyna
Published: July 2023

Przedmiotem interpretacji jest powieść Włodzimierza Kowalewskiego Excentrycy, wydana po raz pierwszy w 2007 roku. Utrzymana w konwencji realistycznej fabuła ukazuje rzeczywistość PRL-u z lat 1957–1958 na przykładzie miasteczka uzdrowiskowego – Ciechocinka. W ówczesne realia wpisany został wątek muzyczny, romansowy i sensacyjny. Pisarz korzysta z konwencji literatury popularnej, by w opozycji do socjalistycznej powagi wykreować klimat zabawy. Wprowadza elementy komiczne w charakterystykach postaci, w dialogach i sytuacjach, używając humoru w celach ludycznych. Jest to podejście empatyczne, którego zamiarem okazuje się rozbawienie czytelnika, a nie wywołanie negatywnych emocji. Zmysł humorystyczny przeważa nad satyrycznym nastawieniem wobec świata przedstawionego.
Wojna polsko-ruska pod flagą biało-czerwoną Doroty Masłowskiej i jej rosyjski przekład: problemy transportowalności ironii (przypadek metatekstu)
Authors:   Uniwersytet im. Adama Mickiewicza w Poznaniu, Starodvorskaia Ekaterina
Published: July 2023

Kwestie związane z transponowalnością ironii, jej „(nie)przekładalnością” od dawna są w centrum uwagi teoretyków przekładu, lingwistów, literaturoznawców, tłumaczy. O ile ironia jako taka to zjawisko w pewnym stopniu uniwersalne w językach i literaturach europejskich, o tyle językowe sygnały jej obecności w tekście literackim są tak różnorodne oraz w tak dużym stopniu związane z kontekstem (językowym, sytuacyjnym, kulturowym etc.), że oddanie ironicznego przesłania w innym języku to dla tłumacza prawie zawsze wyzwanie. Sytuacja jeszcze bardziej się komplikuje, kiedy wykładnikami ironii stają się elementy metatekstowe, zazwyczaj niezwracające na siebie większej uwagi. Wojna polsko-ruska pod flagą biało-czerwoną Doroty Masłowskiej jest osadzona w konkretnych realiach oraz kontekstach, posługuje się najrozmaitszymi dyskursami, łączy ich elementy za pomocą metatekstu i wykorzystuje obraz narratora niegodnego zaufania. W centrum zainteresowania w artykule znajdą się właśnie te cechy powieści (niesprzyjające łatwym rozwiązaniom translatorskim) oraz niektóre decyzje, podjęte przez jej rosyjską tłumaczkę (Irinę Łappo) i dotyczące tłumaczenia ironicznie użytych wyrazów metatekstowych.

Published: July 2023

Artículo basado en la investigación de mi tesis doctoral, Inquisición, censura y literatura espiritual en la España Moderna, en el que demuestro que la literatura espiritual en el siglo XVII no se encontraba en decadencia, debido a las medidas impuestas por la Inquisición y la Contrarreforma, como muchos investigadores han señalado, sino que perduró sin perder importancia y seguidores durante este siglo, continuando la labor de los autores espirituales del siglo XVI, defendiendo una espiritualidad más intimista y de unión cercana a Dios.Palabras clave: Espiritualidad, teología mística, Dios, oración mental
Elementos musicales en la configuración del ideario poético de Federico García Lorca
Authors: Piqueras Flores Manuel
Published: July 2023

En este trabajo se efectúa un análisis parcial de las ideas poéticas de Federico García Lorca a partir de las consideraciones que el propio autor desarrolla tanto en sus textos de carácter teórico como en su epistolario. El artículo se centra especialmente en las reflexiones de García Lorca acerca de lo musical y de su relación con la poesía –especialmente con el Poema del cante jondo, aunque no solo–, para mostrar que no existe en la poética lorquiana una síntesis entre tradición y modernidad, sino una búsqueda de la tradición a partir de la modernidad, en la línea de las propuestas de los compositores que se ocuparon por la música popular española (desde los nacionalistas rusos hasta Manuel de Falla).Palabras clave: ideario poético, música, poesía, modernidad, tradición.
Juicios estéticos y literarios de clérigos en el Quijote: sobre los libros de caballerías
Authors: Santos de la Morena Blanca
Published: July 2023

Si queremos acercarnos al pensamiento de Cervantes en materia religiosa es conveniente someter a análisis los pasajes en los que personajes eclesiásticos de la obra cervantina reflexionan sobre temas controvertidos. En este sentido, por su naturaleza metaliteraria, en el Quijote son especialmente significativos los debates que establecen los personajes acerca de otras obras literarias, especialmente los juicios sobre los libros de caballerías. El caso más paradigmático es, probablemente, el escrutinio de la biblioteca de don Quijote, llevado a cabo por el cura con la ayuda del barbero (I, 6). No obstante, también resultan interesantes los juicios emitidos por el propio cura en otros momentos de la obra, (I, 32; I, 47-48), por el canónigo al final del primer Quijote (I, 47-48), y por el eclesiástico de los duques (II, 32). En este trabajo nos proponemos analizar estos pasajes con el objetivo de observar si la opinión de los personajes religiosos en materia caballeresca puede extrapolarse a la de Cervantes, y posibilitar así una nueva vía de acercamiento al problema del pensamiento religioso de Cervantes.Palabras clave: Quijote, clérigos, religión, crítica literaria.
Estrategias cinematográficas en la narrativa de Rafael Courtoisie: los casos de Goma de mascar y Santo remedio
Authors: Seoane Riveira José
Published: July 2023

Las dos últimas novelas del escritor uruguayo Rafael Courtoisie (1958), Santo remedio (2006) y Goma de mascar (2008), ilustran a la perfección el uso de estrategias adoptadas de la narración visual y transformadas al lenguaje escrito. Las temáticas que presenta en ambas novelas, además de estar estrechamente relacionadas entre sí, confluyen con uno de los motivos capitales del cine contemporáneo: la violencia y su impacto en la juventud mediante las nuevas tecnologías de la (sobre) información. Este estudio pretende analizar, desde una perspectiva temática y formal, qué recursos cinematográficos utiliza el autor en la construcción de sus narraciones a través de sus dos últimas novelas, y qué efectos consigue con ellos.Palabras clave: Rafael Courtoisie, cine, narrativa uruguaya, transmedialidad

Authors: Puteri Saskia Oktaviani , Ratnawati Ratnawati , Vikawati Nura Eky
Published: July 2023

Lung vital capacity of is different for each individual depending on personal characteristics, such as age, body mass index (BMI), and exercise habits or environmental factors, such as exposure to cigarette smoke. This study aimed to determine the relationship between personal characteristics, duration of exposure to cigarette smoke, and lung vital  capacity in passive smokers in one of the areas in Indonesia. This study was a cross-sectional observational analytic study conducted during the period of August to September 2019. Data were collected through interviews and measurements using the Contec SP10BT spirometer. Participants were sampled consecutively with only women who did not smoke but had at least one family member who actively smoked and was over 20 years old participated in this study. Women were selected as the population due to the fact that the proportion of passive smokers among women is higher than men, while the age group of above 20 years old was selected with a consideration of the average age for the optimum lung capacity. The relationship between personal characteristics and a history of exposure to cigarette smoke with lung vital capacity was analyzed using Pearson and Spearman correlation test. There is a significant relationship between age, exercise habits, duration of exposure to cigarette smoke, and vital lung capacity (p=0.000; p=0.018; p=0.000) among the participants of the study. However, further research is still needed to be able to generalize this finding into a broader community.

Published: July 2023

This retrospective descriptive study aimed to understand the outcomes of HFNC therapy in severe COVID-19 patients admitted to isolation ICU during the period of January to June 2021 in Dr. Hasan Sadikin General Hospital Bandung, Indonesia. A total of 134 patients with severe COVID-19 were admitted to the isolation ICU and received HFNC. Among them, 44 patients (32.8%, N:134) were successfully weaned from HFNC and 90 patients (67.2%, N:134) failing HFNC with 10 patients (7.5%, N:134) died on HFNC use, 72 patients (53.9%, N:134) died on ventilator use, 4 patients (2.9%, N:134) moved rooms under HFNC use, and 4 patients (2.9%, N:134) moved to non-ICU isolation with ventilator use as the outcome. Patients’ median age was 60 years, most were male (52.3 %, N:134), median BMI was 25.4 kg/m2, with hypertension and diabetes mellitus as the main comorbidities. There was an improvement in the SpO2 on the first day after the use of HFNC. The ROX index had a median value of 3.6 on the first day, with the lowest ROX index of 3.2 and the highest of 4.4 during the treatment time. There was an improvement in the P/F Ratio in successful patients with a median initial P/F Ratio of 86.7 to 200.1 at the end of treatment. Overall, HFNC improves the hypoxemic conditions in early admission but does not correlate with general patient outcomes.

Published: July 2023

Urbanization and Industrialization have led to release of higher heavy metals amounts into the atmosphere especially aqueous regions. Heavy metals contaminations of potable water have become a serious challenge especially with toxic elements like mercury, lead, zinc, boron and cadmium. Lot of biological constituents has attracted many scientists and researchers due to qualities of cheap and effectiveness for removing heavy metals from waste water. The nanostructured adsorbents exhibit much higher effectiveness and faster rates of adsorption in treatment of water as compared to conservative materials principally because of the remarkably higher surface areas. In the current review, it has been described that the nanomaterials can be used successfully as cost-effective, ecologically friendly, and efficient adsorbents for the elimination of different toxic substances from wastewater.
The rights of Nature: the legal revolution of the 21st century
Authors: Giménez Teresa Vicente
Published: July 2023

The article tries to show how the ecocentric approach, which preaches Ecological Justice, finds full legal recognition today both in Jurisprudence and in Law. Three cases will be studied where Nature is recognized as a subject of law, that is, environmental entities, such as rivers or lagoon, are granted recognition as subjects of law with their own rights, which generates protection and restoration obligations. The first, the Atrato River in Colombia and the second, the Whanganui River in New Zealand. The study of these cases gave me the possibility of fighting for the rights of the Mar Menor, which is the third case study of this work: the Laguna del Mar Menor in Spain, Law 19/2022, of September 30, of recognition of legal personality to the Mar Menor Lagoon and its basin.

The effect of coating concentration of curcumin: H2O on copper winding characteristics
Authors: Abidin Zainal , Siswanto Eko , Wijayanti Widya , Winarto Winarto
Published: July 2023

Each coil of copper produces a magnetic field and the total field inside the solenoid will be the sum of the fields caused by each coil of current. If the solenoid coils are very closely spaced, the internal field will be essentially parallel to the axis except at the very ends. To find out the magnitude of the magnetic field inside the solenoid, you can use Ampere’s law, namely B=μo∙N∙I, where B is the magnetic field strength (T), µo is air permeability (4×10‒7 T m/A), N is the number of turns and I is an electric current. The value of B depends on the number of turns per unit length, N, and current I. The field is independent of the position inside the solenoid, so the value of B is uniform. This only applies to infinite solenoids, but is a good approximation for actual points that are not near the ends of the solenoid.
The research object is 4 identical copper coils with a length of 3 cm, a coil diameter of 2 cm, a cross section of 1.5 mm2 with an inductance value of 2.17 µH. Before coating curcumin on the copper winding, the initial value of the magnetic field strength was 2.54 µTesla. After the coating process of curcumin:H2O concentration, the value of the magnetic field strength increased.
The method used was immersing 4 copper coils with an inductance value of 2.17 µH in curcumin:H2O concentration in a 100 ml volume measuring cup, with the respective concentrations: (20 %:80 %), (40 %:60 %), (60 %:40 %), (80 %:20 %) in a certain time. Then the copper coil conductor is supplied with a 5-volt DC voltage source. Then the value of the magnetic field strength (B) and electric current is measured, the results are compared with the system before immersing the copper coil.
The measurement results showed that the values of electric current and magnetic field strength increased after curcumin coating compared to before treatment. To see the bonding performance of curcumin and copper, the FTIR test and simulation of the curcumin: copper bond were carried out using Avogadro software. In the IR test, there is a strong absorption of aromatic C-C from 1,650 cm-1 to 1,500 cm-1. Whereas in the simulation, the bond between copper and curcumin produces a bond energy of 164.532 kJ/mol or equivalent to 171.12×10-2 eV
Devising a method for determining the aperture brightness of an object using a typical shape of its image

Published: July 2023

The object of this study is the aperture brightness of the image of the object, which has a variety of typical shapes in the frames of the series. It directly depends on the stability of the shooting conditions of the objects under study. Thus, determining the exact aperture brightness of an object in the frame becomes more difficult. For this purpose, a method was devised for determining the aperture brightness of an object using the typical shape of its image on a series of frames.
This method is based on the formation of a typical shape of a digital image of an object based on data from all frames of the series. The typical shape makes it possible to take into account the peculiarities of the formation of the image of the object on each frame of the series. Based on this, a more accurate estimate of the initial approximation of the parameters of all Gaussian images of the object is performed. In addition, the adaptation of the method to the standard shape makes it possible to perform a more accurate assessment of the aperture brightness of the object in comparison with the analytically defined profile. An estimate of the aperture brightness of the object was derived using the least squares method. Due to minimization using the Levenberg-Marquardt algorithm, the use of the method improved identification with reference objects and reduced the number of false positives. The study showed a decrease in the standard deviation of frame identification errors by 5–7 times when using a typical shape of a digital image.
The devised method for determining an object's aperture brightness using its image's typical shape was tested in practice within the framework of the CoLiTec project. It was implemented in the intra-frame processing unit of the CoLiTecVS software for the automated construction of brilliance curves of the studied variable stars. Owing to the use of the CoLiTecVS software and the proposed computational method implemented in it, more than 700,000 measurements of various objects under study were successfully processed and identified

Published: July 2023

This work used soursop as a green corrosion inhibitor to protect API 5L Grade A from detrimental corrodent under produced water. Despite the effectiveness of inorganic inhibitors, recent evidence on their toxicity test suggests that implementing organic inhibitors is substantial to replace synthetic corrosion inhibitors. However, soursop utilization as a green corrosion inhibitor is poorly understood due to the lack of a comprehensive extraction mode and inhibitive mechanism. Several tests were conducted, including weight loss, potentiodynamic polarization, and electrochemical impedance spectroscopy (EIS), to unveil the nature of corrosion inhibition. Fourier Transform Infra-Red Spectroscopy revealed the dominant functional groups to bind with the substrate. The potentiodynamic polarization results show that the inhibitor is a mixed-type inhibitor that influences the anodic and cathodic reactions. The weight loss test showcases the highest inhibition efficiency of 52.62 % upon adding 2 ml inhibitors upon eight observation days. The polarization and EIS results provide that the inhibitor reduces the corrosion rate with higher inhibition of 88.52 %. The mentioned result is associated with the attachment of non-polar and polar Annona muricata Linn functional groups. The primary functional group involves C=O, C‒C and –O.H., which actively bonded to the metal's surface. The aromatic group at a wavenumber of 1,050 and 1,090 cm-1 shows ether's presence and behaves as an adsorption center. In this work, combining three solvents, hexane, acetone, and ethanol, elicits the complete extraction of the predominant compound from soursop

Published: July 2023

In order to guarantee the proper quality of medical products and medicines, the mandatory application of Good Manufacturing Practices (GMP) norms in almost all countries is provided by law. Given the importance of nutritional provision of human portrebs in emergencies, the use of GMP is also relevant in the production of food products for special medical purposes. The object of research is the methodological base, approaches, and norms of GMP application in the manufacture of this product category. It is determined that the implementation of these practices is ensured mainly through measures for raw materials, equipment, personnel, premises, compliance with hygienic requirements, journaling, internal control, response to complaints, monitoring, traceability, product recall. It is established that the basic principle of GMP application is the production of products that will meet the purpose and provisions of the registration dossier.
At the same time, ensuring product quality is a comprehensive concept of ensuring compliance with properties, combining organizational measures at all stages. This activity should be carried out taking into account risk-oriented thinking based on the control of raw materials, packaging, testing in the production and release of goods to the declared characteristics, ensuring high competence of personnel, process and analytical validation. Recommendations on a set of measures aimed at introducing good manufacturing practices at enterprises producing food products for special medical purposes have been compiled and presented. The essence of these recommendations is to identify technological processes, monitor their implementation, provide the necessary resources and measures, establish the process of documenting actions, validation at all stages, including self-inspection
Formation of the quality of holes obtained by drilling in aviation structures made from polymer composite materials

Published: July 2023

The subject of this study is the quality indicators (geometric accuracy, roughness, cylindricity and taperness) of holes obtained by drilling in aircraft structures (AS) made of polymeric composite materials (PCM). The quality indicators of holes in AS made from PCM were studied by using kinematic schemes across and along the direction of drilling. A kinematic scheme of formation of the predicted surface roughness of the hole in AS made from PCM has been built. The calculation of the predicted roughness of PCM holes taking into account the geometry of the drill and drilling modes has been proposed. Experimental studies have been implemented to establish the parameters of predicted roughness, geometric accuracy, taperness, as well as deviations from cylindricity. The methods used were the method of expert assessments and experimental studies of quality indicators of PCM openings. The following results were obtained: the roughness in full-scale experiments turned out to be lower than the theoretical calculated values with a difference of not more than 10...15 %. It was found that roughness, taperness, deviations from geometric precision and cylindricity differ in characteristic rotation zones of the drill from 0° to 360° and depend on the drilling parameters and PCM properties. It was found that the deviation from the hole cylindricity is affected by the shrinkage of the material. The appearance of ovality in the holes of prototypes was established. The results of experimental studies of measurements of hole diameters to establish deviations from cylindricity, geometric accuracy, and taperness met the production requirements for the accuracy of their manufacture. For geometric precision and deviation from cylindricity, the results ranged from 7 to 12 IT grades, and for taperness, from 0.083 to 0.28 % per a hole in AS made from PCM and 9–10 IT grades

Published: July 2023

The object of this study is the process of identifying implicit relationships between public services and the process of forming portfolios and groups of services determined on the basis of the formulated principle of combining services. The task to identify groups of interconnected services, which is relevant in view of the processes of digital transformation in the field of public services, was addressed. Expanding portfolios of public services thru the formed groups of interconnected services could make it possible to better take into account the interests of users, as well as simplify the process of development and reengineering of public services. The proposed approach to form groups of services would reduce the cost and complexity of reengineering services or converting them into electronic form.
The result of research is a new principle of combining or grouping services, which is based on the methods of intelligent analysis. The basis of the proposed principle of forming groups of services is a simple and effective mathematical apparatus of applying similarity coefficients to establish the similarity of sets, which has not yet been used in the field of public services. The presence of interrelationships between services was established based on the analysis of Jaccard and Sorensen similarity coefficients. An algorithm for forming groups of services based on a new principle has been developed. The relationship between services was established as a result of the analysis of the composition of services, that is, the documents or data necessary for the provision of these services. This allows applying the proposed approach without restrictions and additional conditions. The developed algorithm also allows for «What-if» analysis of the obtained results. An illustrative example was considered: for a set of 10 services, 4 groups of services are formed. Suggestions for applying the proposed approach are provided

Published: July 2023

The study is devoted to the features of the fashion industry transformation into a sustainable ecological ecosystem. The sociocultural sphere of the fashion industry was chosen for analysis, since this sphere directly depends on the public's attitude to the fashion industry cyclical model of functioning. The relevance of the choice is confirmed by the lag in the sociocultural factors study from the results of technological, artistic, aesthetic and environmental aspects research. The problem is exacerbated by the lack of a single center for managing the socio-cultural sphere in a heterogeneous environment of the ecosystem. The purpose of the study is to find ways to regulate the fashion industry socio-cultural sphere in the in conditions of a common control center absence.
The concept of regulation the fashion industry socio-cultural sphere was proposed based on synthesis the digital and humanitarian technologies in the process of its transformation into a sustainable ecological ecosystem. Regulation implemented by generation of stimulating impacts on the independent participants of the cyclic process in order to coordinate their behavior for achieving the common goals of the system. For the formation of influences, humanitarian technologies were chosen that able to influence on the behavior of the process operators. The list of digital humanities curricula of iSchool educational network was chosen as a data source. To create incentives, a techno-humanitarian complex was formed, consisting of filtered and harmonized digital humanities and ecological fashion design. It is shown that this complex is able to influence on the socio-cultural components of the fashion industry innovative potential by stimulating of the ecosystem subjects behavior. The possibility of implementing the proposed concept demonstrated by developing a functional model of fashion industry techno-socio-cultural system with the participation of the techno-humanitarian complex

The development of Internet technologies together with mobile and computer technologies have formed smart technologies that allow the formation of both cyber-physical and socio-cyber-physical systems. The basis of smart technologies is the integration of wireless channel standards with mobile and computer protocols. 4G/5G technologies are integrated with various web platforms, taking into account the digitalization of services in cyberspace. But the SSL/TLS protocol, based on the hybridization of symmetric encryption algorithms with hashing algorithms (AEAD mode), which is supposed to provide security services, is vulnerable to “Meet in the middle”, POODLE, BEAST, CRIME, BREACH attacks. In addition, with the advent of a full-scale quantum computer, symmetric and asymmetric cryptography algorithms that provide security services can also be hacked. To increase the level of security, an improved protocol based on post-quantum algorithms – crypto-code constructions is proposed, which will ensure not only resistance to current attacks, but also stability in the post-quantum period. To ensure the “hybridity” of services, it is proposed to use the McEliece and Niederreiter crypto-code constructions (confidentiality and integrity are ensured) and the improved UMAC algorithm on the McEliece crypto-code construction. Taking into account the level of “secrecy” of information, it is suggested to use various combinations of crypto-code constructions on different algebraic geometric and/or flawed codes. The use of crypto-code constructions not only provides resistance to attacks, but also simplifies the formation of a connection – the parameters of elliptic curves are used to transmit a common key. This approach significantly reduces the connection time of mobile gadgets and simplifies the procedure of agreement before data transfer

Researching the changes that are taking place in the era of digitalization makes it possible to track the digital footprint of consumers and form new trends and models in business management. The object of this study is the digital literacy of citizens. The vast majority of society cannot imagine their life without online activity, viewing web pages, sites, and social networks. That is why there is an increasing need to expand knowledge of digital literacy. The purpose of this research is the formation of the "BEST" matrix, which makes it possible to determine the level of knowledge and possession of digital competencies of the staff. For diagnosis, 10 criteria were selected, and the specific weight of each of them was calculated, which was summarized in the survey form. Determination of the importance of each factor is carried out by the method of expert assessment, taking into account that the overall coefficient of importance=1 for each group of factors. Achieving maximum efficiency (5‒10 points) will ensure a stay in the "S" segment of the matrix, which indicates a high level of business process management, knowledge and compliance with the descriptors of digital competencies by the staff. This contributes to the solution of the problem of knowledge of the descriptors of digital literacy and makes it possible to improve the efficiency of the enterprise, as well as to repulse cyber attacks in a timely manner. The application of defined digital competencies will allow making optimal decisions in the process of applying digital skills, while ensuring the uniqueness of digital literacy in business management. The results can be used by enterprise managers to analyze and build countermeasures against data leaks or cyber attacks. This will contribute to the establishment of cooperation between enterprises and stakeholders and the formation of consumer trust
Development of technology for the production of useful jelly candies from cucurbit crops on a natural basis

Published: July 2023

The object of the study are the fruits of cucurbits crops, as well as confectionery products based on the fruits of watermelons and melons. The fruits of watermelons and melons are not processed on an industrial scale for a number of reasons: the lack of technological solutions for primary processing and preparation for processing, the instability of raw materials for processing. The pulp of watermelons must be processed within 5 hours under certain conditions; in the pulp of melons, changes in microbiological indicators begin within an hour of storage at room conditions. Because fruits have a high moisture content, the solution for effective fruit processing is to bind this moisture with thickeners and produce jelly candies. Sweets made without antioxidants did not withstand the standard shelf life for jelly sweets, and the growth of mold fungi increased. The reason may be the low acidity of the raw material. Citric acid was added as an antioxidant. There were problems of taste and smell; citric acid interrupts the natural smell of raw materials. During the search, the powder of dried, red-fruited rowan was chosen. The finished product had a barely perceptible natural aroma, the powder did not affect the taste. There were inclusions in the cross-section, but the appearance became more attractive.
Jelly sweets without the addition of rowan powder had active mold growth on the 7th day of storage at a temperature of 22–25 °C; with the addition of rowan powder under the same storage conditions, they showed growth on the 16th day.
The finished product meets all physical, chemical, and microbiological standards. The shelf life of such jelly sweets at a temperature of +6 °C in sealed packaging is up to 30 days without mold formation
Optimizing the utilization of structural resources of flight simulator motion systems
Authors: Kabanyachyi Volodymyr , Hrytsan Serhii
Published: July 2023

The object of the study is a six degrees-of-freedom motion system of the synergistic type of a flight simulator. The latter is the main technical means for training pilots and means of research and development of aircraft. The task of optimal utilization of its structural resources was solved, which provides an opportunity to improve the quality of motion cueing. The result is the developed method, which ensures optimal use of structural resources of motion systems of flight simulators. This is explained, first of all, by the use of the developed simplified operator for converting the movements of jacks into the movement of a motion system along individual degrees of freedom on the basis of quadratic approximation. Given this, it became possible to describe the coordinates of the centers of the axes of rotation of the motion system by cubic spline functions. Secondly, the solution of the task of estimating the structural resources of the motion system along linear degrees of freedom on the basis of the developed criterion was carried out by an effective modified method of the deformed polyhedron. This method combines the random search method in the first steps of the search and the gradient method in determining the global extremum. Thirdly, the problem of determining the dependence of the coordinates of the pitch and yaw axes along the pitch angle was stated and solved. Owing to the optimal utilization of the structural resources of motion systems, the coordinates of the axis of their rotation along pitch are as close as possible to the coordinate of the axis of the aircraft. Thus, the quality of motion cueing on the flight simulator is significantly increased and it is possible to use motion systems with shorter lengths of jacks, and therefore, to reduce the cost of their manufacture and operation
Devising a method for detecting “evil twin” attacks on IEEE 802.11 networks (Wi-Fi) with KNN classification model

Published: July 2023

The object of research is IEEE 802.11 (Wi-Fi) networks, which are often the targets of a group of attacks called "evil twin". Research into this area is extremely important because Wi-Fi technology is a very common method of connecting to a network and is usually the first target of cybercriminals when they attack businesses. With the help of a systematic analysis of the literature focused on countering attacks of the "evil twin" type, this work identifies the main advantages of using artificial intelligence systems in the analysis of network data and identification of intrusions in Wi-Fi networks. To evaluate the effectiveness of intrusion detection and cybercrime analysis, a number of experiments as close as possible to real attacks on Wi-Fi networks were conducted.
As part of the research reported in this paper, a method is proposed for detecting cybercrimes in IEEE 802.11 (Wi-Fi) wireless networks using artificial intelligence, namely a model built on the basis of the k-nearest neighbors method. This method is based on the classification of previously collected data, namely the signal strength from the access point, and then continuous comparison of the newly collected data with the trained model.
A compact and energy-efficient prototype of a hardware and software system has been designed for the implementation of monitoring, analysis of ethernet network packets and data storage based on time series. In order to reduce the load on the computer network and taking into account the limited computing power of the system, a method of data aggregation was proposed, which ensures fast transfer of information.
The results, namely 100 % of test cases (more than 7 thousand), were classified correctly, which indicates that the chosen method of data analysis will significantly increase the security of information and communication systems at the state and private levels
