Cross-influence of Risk, Return, and Governance on Decision-Making in Hydropower Investments
Authors: Karki Dipendra
Published: March 2024

The sustainable growth of an economy pivots on a robust financial system, particularly in the context of capital availability. This study analyzes the behavior of investors towards initial public offerings (IPOs), focusing on the hydropower development sector in Nepal. The research explores the multifaceted relationship between factors such as risk, return, and governance on investor behavior, considering elements like Idiosyncratic risk (IR), timing of issue (TIPO), Bandwagon effect (BE), expected return (ER), sectoral performance (SP), corporate governance (CG), pre-issue financial health (PFH), and marketability (MKT). Additionally, sociodemographic variables and their connection to investor behavior are examined. Employing a descriptive research design, the study involves a sample size of 392 individuals, selected through a convenient sampling method. The study's main finding documented that idiosyncratic risks, expected returns, and corporate governance stand out as crucial factors influencing investment decisions (P < 0.05). Notably, the regression analysis indicated the absence of a significant impact from market risks (P > 0.05), including the bandwagon effect and IPO timing, on investor behavior towards hydropower IPOs. This finding suggests that Nepalese investors prioritize returns and organizational governance over market risks, despite having significant concerns regarding idiosyncratic risk. The analysis also reveals significant associations between investor behavior and sociodemographic variables like age, education, occupation, and primary investment objectives (P < 0.05). This study offers valuable insights and implications for investors seeking to align investments with their goals. Hydropower developers should prioritize investor protection and transparency, while regulators must enhance disclosures, shareholder accountability, and project oversight.

«Жить по-иному»: эстетический опыт как опыт преображения
Authors: Nikonova S. B.
Published: March 2024

The intensity of aesthetic experience can be seen as endowed with the power to transform and transfigure. This effect is revealed in the article through the analysis of Rilke’s poem “The Archaic Torso of Apollo” (1908), which describes a concentrated aesthetic experience when contemplating a sculptural fragment, as if this experience called for a change in one’s life, but without indicating the direction of change. The nature of this experience is defined in terms of the concept of presence of H.U. Gumbrecht. The absence of a meaningful indication in aesthetic experience connected with the perception of a work of art correlates with Kantian definitions of the sublime. The aesthetically sublime indicates not concrete content, but awakens in us the idea of the infinite, and it, in turn, can be associated both with the religious experience, and with the principle of transforming and transcending oneself as the basis of a person’s spiritual life. Accordingly, it is concluded that in the post-metaphysical secular epoch, the intensity of aesthetic experience, appealing to transformation and to “another life”, replaces the metaphysical search for supernatural harmony and religious faith.
Редукция трансцендентного как основание имагинативного поворота в неопрагматизме
Authors: Magomedova Yu. S.
Published: March 2024

The article is devoted to the analysis of the conceptual and methodological grounds of the imaginative turn made within the framework of neopragmatist discourse. The specific works of R. Rorty, H. Putnam, and M. Johnson are used as examples to present the features of the interpretation of ethics, moral law, and rationalist tradition. The article emphasizes the process of metaphorization of key concepts of Kant's ethics by the neopragmatists. It is argued that for Putnam Kant's ethics has value first of all for its figurative component, the presence of colorful metaphors based on the core concepts of the Judeo-Christian tradition. In adding, it is suggested to critically evaluate the position of Johnson, who deals in detail with Kant's main moral law, the meaning of the categorical imperative. It is established on the basis of the fact that neopragmatists have reduced the transcendental dimension that the crucial role begins to be taken by the sensuality of the empirical subject and imagination as a moral moderator. The author refers to this phenomenon by the term "imaginative turn". Citing the works of Russian researcher E.N. Ustyugova the author makes a conclusion that for neopragmatists the human being turns out to be an empirical natural phenomenon, and aesthetics is the only fundament for moral judgments.

Authors: Manoharan Kesavan , Dissanayake Pujitha , Pathirana Chintha , Deegahawature Dharsana , Silva Renuka
Published: March 2024

The efficiency of workforce operations has a significant impact on how profitable a construction firm is. Studies from the past demonstrate that a variety of labour-related concerns have been affecting the construction sector in Sri Lanka and other developing countries, which has a negative impact on the efficiency of construction activities. Construction engineers are crucial resources who can play a key role in the development of decisions and regulations pertaining to construction labourers. This study intends to examine the influence of labour-related causes on the efficiency of construction operations in Sri Lankan road construction projects from the perspective of construction engineers. The significant labour-related causes were identified by a comprehensive scholarly review. Then, a questionnaire survey was conducted among 31 road construction contractors in Sri Lanka. The impact level of each cause was calculated using the Relative Importance Index (RII) method. A total of 26 causes were found to be critical, where labour skill shortage, labour discipline, labourers’ poor ability of reading, understanding, speaking and writing, labourers’ lack of thinking abilities and their communication problems were the top five ranking causes in the list. The validity and reliability of the study findings were established using statistical testing. The activities required in the construction site management processes were also evaluated in relation to the key variables identified through a number of industry consultative sessions. These consultative outcomes further confirmed the validity of the study results. The study findings will significantly aid in modernising current industry practices to boost output and efficiency. Even though the study findings are applicable and limited to the Sri Lankan road construction sector, some of those may still be considered in other developing sectors/countries.
Homochiral Selection in a Non-equilibrium Process: Origin of Life
Authors: Tennekone Keerthi
Published: March 2024

Chemistry and therefore life is a manifestation of the electromagnetic interaction which cannot distinguish rightfrom left, and all chemical reactions in the absence of an external chiral bias produce equal amounts of right and left-handed molecules. Nevertheless, the living matter is chiral biased and generally constituted of only one of the enantiomers, right handed or left handed. The origin of biochemical chirality remains an unresolved problem believed to be concurrent or an essential prerequisite to origion of life. Most hypotheses attempting to understand this issue, attribute homochiral selection to a biasing influence and presupposition that asymmentry can be begotten onlyfrom asymmetry. A system in thermodynamic equilibrium in the absence of a constant external chiral influence is indeed racemic and contain equal proportions of both enantiomers. Living systems and the origin of life itself are not equilibrium situations and could deviate from racemicity. A mathematical model ispresented to show that any enant iomeric selfreplicating molecule created in the racemic prebiotic medium can proliferate exhausting all precursor molecules of both handedness. The homo chirality of life is a continuation of this non-equilibrium process.

MODEL ANALYSIS OF DEMOGRAPHIC PROCESSES IN THE POPULATIONS OF FUR-BEARING HUNTING ANIMALS INHABITING THE JEWISH AUTONOMOUS REGION
Authors: Revutskaya O.L. , Neverova G.P
Published: March 2024

Among biological resources, hunting animals, including fur-bearing species, take a special place. The study of such populations dynamics is a crucial stage in fur harvesting planning and organizing. This work aims to describe and analyze by mathematical modeling methods the dynamics of fur-bearing animal populations inhabiting the Jewish Autonomous region. We consider the populations whose newborn individuals reach maturity by the next breeding season, for example, squirrel, white hare, Manchurian hare, raccoon dog, and weasel. The study is based on the discrete-time model of population dynamics with a simple stage structure. To take into account density-dependent regulation of population growth in the model, birth or survival rates of the immature class are represented by exponential functions of the total population size. To estimate the model parameters, we propose the use of data corresponding to the total population size. The obtained point estimates, based on this approach, are demonstrated to be within the range of biologically meaningful parameter values and exhibit the population dynamics similar to those observed in nature. Specifically, according to the model estimates, squirrel and hare populations are characterized by unstable dynamics with sharp annual fluctuations. In general, the proposed approach for parameter estimation allows for analyzing and modeling the age composition of the animal population, as well as determining demographic parameters that characterize the animal population dynamics based on the total population size data.
FEATURES OF POPULATION DYNAMICS SYNCHRONIZATION IN THE SYSTEM OF THREE POPULATIONS RELATED BY MIGRATION

Published: March 2024

The article is devoted to the study of oscillations (cycles) synchronization in a system of three populations coupled by migration in a circle. We consider a discrete time model of population dynamics, which is a system of three identical dissipatively connected logistic maps. One-dimensional bifurcation diagrams (trees) were constructed, supplemented with the capture index of the population numbers cycles phases at adjacent sites. We conducted numerical experiments that show phase multistability – the cycles coexistence with different phases. Using qualitative methods for studying dynamic systems, a complete phase portrait of the model is constructed, showing that in the phase space there are several periodic points corresponding to elements of synchronous (in-phase) and asynchronous (out-of-phase) cycles. The 2- and 3-cycle stability conditions are investigated. It is shown that these two cycles are represented by three options: 1) a fully synchronous regime, when the abundances in the three populations coincide at any point in time; 2) a partially synchronous regime, when abundances coincide only for two populations, 3) a non-synchronous (out-of-phase) regime, when all three numbers have different values. For a 2-cycle, the third regime is unstable, possible as part of a long transition process. We found that for the 3-cycle, besides to the synchronous and partially synchronous regime, it is possible a stable out-of-phase behavior of three populations. It is shown that stable and unstable periodic points lie on certain surfaces (invariant manifolds), which separate the areas of attraction for regimes with different degrees of phase synchronization.

This article highlights the importance of emotional and spiritual intelligence in human life. The capacity to express, understand, see, use, and control one's own or others' emotions is referred to as emotional intelligence. While, spiritual intelligence refers to the ability to understand deeper meanings, values, purposes, and unconscious aspects of one's self including the ability to integrate these meanings, values, and purposes in conducting more meaningful and creative lives, a positive attitude and mindset while facing hardship in any situation or circumstances. The focus of this article is on the emotional and spiritual intelligence revealed in the Prophet's leadership, including intrapersonal and interpersonal skills. The method employed for this research is qualitative, focusing on the content analysis of books and articles related to the concept of emotional and spiritual intelligence. The findings of this article are the multifaceted aspects of good character in Islamic ethics, is a vast area of behavior that cannot be constricted into a concept such as, Emotional intelligence. Emotional and spiritual intelligence from Islamic perspective is distinctive and different from emotional intelligence in secular outlook. As a key component of the Prophetic model of leadership, the acuteness of his intrapersonal and interpersonal emotional awareness and comprehension became the fundamental components that rendered to his ability to control his emotions effectively which makes him known as successful leader in the history of humanity.
Driving Factors for Having the Feeling of Resentment towards God among Muslim Adolescents: Its Phenomena and Solutions
Authors: NADA ABDELRAHMAN MOHAMED , AHMAD MASITOH
Published: March 2024

The article aims to study the causes that lead to the development of Misotheism (a sense of resentment or embitterment towards God or theistic belief in general) among Muslim adolescents.  Previous studies have tackled the issue from its atheist phenomenon without investigating its causes. Therefore, the study focuses on the phenomenon of resentment and embitterment towards God, its driving factors in initial stages and its evolution into atheism among Muslim teenagers. The research highlights the importance of defending against malicious attempts from the critics of Islam who are engaged in efforts that result in severe harm to the psychology of Muslim youth everywhere. The study uses qualitative methods in which library research, method of analysis and observation are applied. The finding shows that there are three main factors that lead to this phenomenon; namely: psychological, social and cognitive causes. The psychological causes for the rebellious behavior among youth are mainly due to family breakdown.  As for the social causes, they are owing to the rigidity of customs and traditions in the name of religion, Islamophobia, social injustice, and the excessive veneration of people and promotion of narcissistic behavior, while the cognitive reasons are embedded in the problem of life challenges, addictions, and social evils. The study also proposes some practical solutions for the issues discussed.

The concept of an international payment system based on the integration of CBDC systems into the blockchain
Authors: Pashkov Artem Andreevich
Published: March 2024

In many countries, central bank digital currency (CBDC) systems are being developed or tested. Although they are fully operational in only a few countries, the interest they have garnered suggests that it is highly likely that in the near future, many nations will use three forms of money: cash, non-cash, and digital. If the experiment proves successful, digital currencies may gradually replace cash and potentially reduce the share of non-cash transactions. The potential for the use of digital money is immense. Considering the trend towards economic globalization, it is conceivable that the national systems on which they are based could be integrated into an international payment system using blockchain technology, capable of conducting cross-border transactions in real-time with currencies as well as other assets. The article describes the concept of such a system and the opportunities it opens up.
Artificial intelligence through the prism of thematic research on ResearchGate web portal
Authors: Machulin L.
Published: March 2024

Different instances of generative artificial intelligence (GenAI) in a short time have made a significant impact on the world’s economic and political scene. Before October 2022, processes of automatization and robotization of manufacturing didn’t have an immediate connection with artificial intelligence in the minds of most people. But mass and sudden infiltration of GenAI into the everyday life of many people around the world caused an immediate reaction from scientists, public figures, politicians, managers and heads of whole sectors of the economy. Thousands of scientific articles on related topics were published in the last two years: everyone at once started talking about fantastic possibilities, and also threats, which this new technology can usher in for our societies. Thus, for public thinking GenAI finally linked automatization with artificial intelligence.

This paper provides an analysis of problems and prospects, through which scientists are trying to understand different societal processes linked to adoption of AI. For this purpose, the author of this paper analyzed the contents of papers published on this topic on the ResearchGate web portal in 2023, with the choice of the source for representative material motivated by scientific credibility of ResearchGate combined with its wide reach. Ten most popular articles were specifically targeted for final analysis, through which societal trends brought on by AI adoption were described. Although a selective meta-analysis of articles published during the first year after ChatGPT release can’t provide a full understanding of AI potential and possible threats to society, the conclusion can still be reached that a cardinal shift in society’s attitudes towards its own future is required.

From the ten articles analyzed, four are related to changes required to the education system, four are about AI’s influence on the labour market, one article talks about the possibility of AI-human competition and one is about the AI potential in agriculture. Most articles mention the need for legislative changes in terms of labor protection and education reforms in-line with new digital reality.

Metafory i podobieństwa w interpretacji osób z uszkodzeniami móżdżku
Authors: Jodzio Krzysztof
Published: March 2024

Cel pracy: Móżdżek współuczestniczy zarówno w koordynacji czynności ruchowych, jak i regulacji procesów psychicznych. Objawy uszkodzenia móżdżku należą do zróżnicowanych, relatywnie mało swoistych i trudnych do usystematyzowania. Celem badań eksploracyjnych była neuropsychologiczna diagnostyka hipotetycznych zaburzeń wybranych procesów (meta)językowych i poznawczych, zaangażowanych w rozwiązywanie problemów zawierających metafory i podobieństwa. Charakterystyka zaburzeń uwzględniała ich epidemiologię, nasilenie, kliniczną specyfikę oraz związek ze zmiennymi socjodemograficznymi.
Metoda: W badaniach wzięło udział 25 dorosłych z izolowanym uszkodzeniem móżdżku, najczęściej naczyniopochodnym. Posłużono się trzema testami: podtestem Podobieństw ze Skali WAIS-R (PL) oraz dwoma testami przetwarzania metafor, pochodzącymi z Baterii do badania funkcji językowych i komunikacyjnych prawej półkuli mózgu (RHLB-PL), tj. Testem metafor pisanych (TMP) i Testem wyjaśnień metafor pisanych (TWMP). Na wstępie obliczono wartości średnie i odchylenia standardowe dla całej grupy. Ponadto, na podstawie danych i norm zamieszczonych w podręcznikach testowych, osobno oceniono wyniki każdego pacjenta. Zamieniano kolejno indywidualne wyniki surowe na wyniki przeliczone, wyrażone w centylach (Podobieństwa) albo w skali stenowej (Testy metafor). Dzięki tej transformacji każdy wynik indywidualny w danym teście sklasyfikowano jako prawidłowy przeciętny albo niski (poniżej przeciętnej), względnie wysoki (ponadprzeciętny).
Wyniki: Wykonanie Podobieństw w całej grupie osiągnęło poziom poniżej przeciętnej, przy czym istotne problemy z rozwiązaniem podtestu (<25 centyla) miało 9 badanych. Kolejnych 7 chorych uzyskało zaledwie 8 punktów przeliczonych, interpretowanych jako pogranicze normy. Z kolei wyniki pacjentów w TWMP osiągnęły wartość w przedziale 5–6 stena. Aczkolwiek wykonanie TWMP w grupie ogólnie nie odbiegało od normy, blisko połowa badanych uzyskała wynik, który nie przekroczył 4 stena. Dla porównania, średni wynik w TMP był relatywnie wysoki. Wynik niski (<4 stena) uzyskało tylko 4 chorych. Szacunkowa analiza profilowa przeprowadzona na podstawie wzorca wszystkich wyników testowych (wyrażonych dychotomicznie jako: wynik [ponad]przeciętny lub niski) ukazała ich intra- oraz interindywidualne zróżnicowanie, którego kliniczną ilustracją były heterogeniczne, często wybiórcze zaburzenia zbadanych funkcji. Korelatami socjodemograficznymi wyników testowych okazały się wiek i wykształcenie.
Konkluzje: U większości chorych stwierdzono rozmaicie nasilone deficyty poznawcze w postaci zaburzeń rozwiązywania problemów zawierających metafory i podobieństwa. Charakterystyczna była przewaga zaburzeń procesów samodzielnego myślenia asocjacyjnego, w tym wnioskowania przez analogię oraz interpretacji i werbalizacji pojęć, nad ogólnie prawidłowym stanem samej wiedzy językowej, także w zakresie znaczeń figuratywnych.
Estimation of influence of cracks in bending reinforced concrete elements on their fire resistance

The paper considers possible scenarios of cracking during heating and their impact on fire resistance using the example of a bending reinforced concrete structure (beam). It is shown that if the calculated critical temperature of reinforcement is less than the critical temperature of concrete (this indicates a significant load on the structure), then cracks in the tensile zone of concrete are formed after reaching the second stage of the stress-strain state. The concrete of the protective layer does not have time to degrade, the depth of the crack remains constant, and the fire resistance limit is calculated taking into account that the thickness of the protective layer of concrete is reduced by the depth of the crack opening. If the calculated critical temperature of the reinforcement is greater than the critical temperature of the concrete (this indicates a slight load on the structure), then cracks are formed as a result of the degradation of the surface layer of concrete. Their depth should constantly increase with the progression of the concrete layer heating to the critical temperature. In this case, the calculation of the fire resistance limit can be performed without taking into account the formation of cracks. Based on the considered assumptions, a methodology for assessing the impact of cracks on the fire resistance limit of bending reinforced concrete structures is proposed, which consists in analyzing the possibility of open cracks (which is facilitated by heating) and estimating their depth. At the next stage, the heating time of the concrete layer to the crack opening depth τΔ1 and the temperature in the crack after this time are estimated. Next, the time until the critical temperature of the reinforcement τΔ2 is estimated when the concrete layer is heated from the bottom of the crack to the reinforcement. The fire resistance limit is defined as the sum of τΔ1 and τΔ2. The results of the calculations according to the proposed methodology showed that the presence of open cracks in bending reinforced concrete structures can almost halve the fire resistance limit.

This research analyses scientific publications that highlight the problems of evacuation of people during emergencies and the latest methods, techniques and strategies. It is determined that the PATHFINDER software complex gives a more accurate calculation compared to the simplified analytical model. The PATHFINDER software complex allows to simulate evacuation in various buildings and areas. Moreover it gives a wider range of possibilities, such as: simulation of evacuation of people with disabilities; ability to set and adjust the speed of agents in different sections of the escape route; the presence of a function that regulates the onset of movement of agents in a given behaviour. In this work the computer simulation of the actual time of evacuation of people from the integral property complex of industrial and household facilities was carried out. The duration of the evacuation of people from the rooms of buildings and structures bases on the model of the movement of people to the exit in one of the following ways: based on a simplified analytical model of human flow; based on a mathematical model of the individual-flowing movement of people from a building or structure; based on a simulation-stochastic model of human flows. These calculations were performed in accordance with the recommendations and instructions using the PATHFINDER software for the two most likely fire scenarios. According to the scenario, the fire occurred in the room with the highest fire-hazardous load or in the room with the smallest volume: scenario 1 - fire occurs in the hot shop; scenario 2 - a fire occurs in the administrative room. The software provides an opportunity to quickly calculate various ways of evacuating people from the rooms. The use of PATHFINDER software gives more accurate results than the calculation given in regulatory document, due to the greater detalization of the evacuation calculation, and also helps to avoid possible errors and reduce calculation errors.
Limit state of reinforced double-hinged arches of i-section
Authors:   Odessa State Academy of Civil Engineering and Architecture, Soroka M.
Published: March 2024

The method of determining the limit load for double-hinged arches is considered. The calculation is performed using the limit equilibrium method. The cross-section of the arch is taken in the form of a reinforced I-beam. The strain-deformed state of the I-beam material is described by the Prandtl diagram. But unlike the classical diagram, it has different yield points under tension and compression. The reinforcement material is described by the classic Prandtl diagram with the same yield strength in tension and compression.In most cases, the ultimate equilibrium of the cross-section is based on the use of one factor ˗ the plastic moment, upon reaching which the cross-section enters a plastic state with the possibility of unlimited deformation. But such an approach cannot be adopted for an arch, as significant longitudinal forces arise in its sections. Ignoring longitudinal forces leads to errors in determining the ultimate load. Therefore, for arches, when determining the limit state of the cross section, it is important to take into account both the bending moment and the longitudinal force. That is, for the transition of the section to the limit state, it is necessary to apply a limit moment to it, which corresponds to a certain longitudinal force. This leads to the concept of the region of cross-sectional strength, constructed in the coordinates of the bending moment - longitudinal force. The boundary of this region indicates the limit state of the cross-section and is described by the flow conditions, which can be obtained by considering the plastic equilibrium of the cross-section. Using the flow conditions, the equilibrium equation of the arch and some constraints, it is possible to formulate an optimization problem for finding the limit load. Limit load (objective function) is the smallest load that satisfies the arch equilibrium equation, yield conditions and constraints. The project variable is the coordinate of the cross-section that enters the plastic stage. The solution of this problem for arches of constant and variable stiffness was performed using electronic spreadsheets. Arch calculations were also performed in PC Lira-CAD. A comparison of the calculation results showed a satisfactory convergence.
Український історичний роман: шляхи становлення та розвитку

The experience accumulated by the art of words never goes away. At a certain stage of literary development, it can be exhausted to a certain extent, only to be revived in a new context in a modified form. The relevance of the study of historical prose, in particular its ways of formation and development, specificity, themes, is quite natural, since works about the national past allow the reader to consciously or sporadically immerse himself in the meaning of life realities, in particular to understand the moral and ethical ideals of the Ukrainian people, the physical and spiritual endurance of the participants in the national liberation struggle, and the deep human values that are often much more expressive and accurate in historical prose than in sociological and historical research. The fiction model of the heroic past serves to shape historical thinking, to deepen an individual’s understanding of his or her own place in society, and to help individuals find ways to self-knowledge and self-affirmation.
The article traces the genesis and main stages of formation of the Ukrainian historical novel, starting with the novel «Zynovii Bohdan Khmelnytskyi. Istorychna kartyna podii, kharakteriv, i zvychaiv XVII stolittia v Malorosii (Zynoviy Bohdan Khmelnytsky. A Historical Picture of Events, Characters, and Customs of the Seventeenth Century in Little Russia)» by Pavlo Biletsky-Nosenko — through the novel «Chorna rada. Khronika 1663 roku (Black Council. The Chronicle of 1663)» — to contemporary works about the past by Pavlo Zahrebelnyi, Roman Ivanychuk, Valerii Shevchuk, Yurii Mushketyk and others.
The specifics of historical novel prose are elucidated, the essence of the concepts of «historical novel» and «artistic and historical truth» is revealed, the role of fictional conjecture and fiction is determined. The article summarises the views of domestic researchers of historical prose on its typology.

One of the central tasks of the development of modern building materials science is the search, development and synthesis of new modifying components for cement composites that can provide traditional materials with new unique characteristics. The current environmental situation worldwide contributes to the fact that building materials must safe for nature, humans and animals. This article considers the possibility of using bismuth titanates as a fine additive to cement composites, which can provide traditional cement based materials with bactericidal properties, as well as the ability to self-cleaning due to the mineralization of organic and inorganic pollutants adsorbed on the surface of the material. During the experiment the additive was synthesized by citrate technology and introduced into the cement composition in the form of a stabilized suspension instead of mixing water. The optimal methods of processing to stabilize suspensions of bismuth titanates particles were studied, which is an important factor for achieving uniform particle distribution in the volume of the cement composite. There was an increase in compressive strength on the first and third days of hardening from 29 to 42 MPa (by 31, 38 and 45%) and from 53 to 70 MPa (by 28, 30 and 32%), respectively. At 28 days age the compressive strength increased from 83 to 97 MPa (by 2, 9 and 14%) compared with the control sample.

The paper deals with the process of production and properties of foam glass concrete – a composite material consisting of modified gypsum binder and granulated foam glass as an aggregate. Foam glass concrete has high strength, durability, environmental friendliness and low thermal conductivity, which makes it a promising material for wall structures. Optimal packing densities were obtained by using programs developed by the authors in the Python programming language to calculate the optimal diameters of three fractions of granular foam glass in an orthogonal or hexagonal packing model. The compressive and flexural strength and thermal conductivity coefficient were investigated on samples of different compositions. The value of the thermal conductivity coefficient of the foam glass concrete was reduced due to the air-entraining additive. In conclusion, the optimum composition of foam glass concrete was proposed taking into account all investigated parameters.

The purpose of this study is to classify COVID-19 CXR(Chest X-Ray) images using a CNN(Convolutional Neural Network) modified from AlexNet using a transfer learning method so that it can be used as an auxiliary method when diagnosing diseases in medical settings. The Dataset used in the experiment uses "COVIDGR-1.0 Dataset". "COVIDGR-1.0 Dataset" is a collection of 784 anonymized X-ray images and, in collaboration with a team of radiologists, built into the dataset by labeling protocols. The proposed CNN is a fine-tuned build of pre-trained AlexNet, which takes the "COVIDGR-1.0 dataset" as input and categorizes it into Normal, Mild, Moderate and Sever according to the labels and categories. Experimental results of the disease classification of CXR images show that the AUC(Area Under the Curve) is 0.8781, with accuracy of 87.81%.
It is believed that the results of this study can be used in the following fields. First, it can be used as an auxiliary tool for diagnosing lung diseases. Second, if the data set is ready, it can be used to classify other diseases. Third, data can be stored separately through classification. Fourth, in the medical field, the object to be classified can be imaged using a smartphone and then classified and stored.
This study has the following limitations. The problem with automatically classifying diseases is the vastness and integrity of the dataset. If the data is not prepared, it will cause problems with the accuracy of classification. And in the medical field, doctors' decision-making (diagnosis) is not limited to image data. There is a limitation in that doctors make decisions based on comprehensive data and that medical decisions cannot be made by machines without the doctor's intervention. Determining the decision threshold in decision making problems by AI is also an important limitation. This is because setting reference points for sensitivity and specificity is not the domain of AI experts but of experts in the field. Therefore, medical staff in the field must participate in the process of developing AI in the medical field.
Future tasks include continuing research in connection with program input stage development, performance improvement, app development, and medical big data servers.
