An anonymous survey was conducted on the author’s questionnaire of students of the social college of Moscow. The questionnaire included 26 questions related to health, complaints about well-being, fatigue, lifestyle, attitude to the chosen specialty. The study was cross-sectional. 289 people aged 15 to 19 were interviewed. Data processing was performed with the assessment of average values and the use of evidence-based medicine criteria and the calculation of health risks. The purpose of the research is to study the influence of health and lifestyle on the wellbeing of students and orientation to the chosen profession. The results showed that one in five had a chronic pathology with a predominance of diseases of the gastrointestinal tract and 20 % had reduced vision. 41.2 % of students were often ill in the first year, and by the third year their number was decreasing. Bad habits were common among students: 38.8 smoked in the first year, and half as much in the last. one in five people consumed alcoholic beverages. Good nutrition is important, but 13.8 %- 20 %., students rated their nutrition as poor. 20 % had a hot meal three times a day, and 30 % had it only once. The results indicate the need for classes with students on the basics of proper nutrition. Students with chronic diseases were more tired after classes, which teachers need to take into account. Among the students, the number of those who liked the profession increased in the dynamics of learning, which indicates the importance of practice.

Currently, melanoma of the skin is an urgent medical and social problem. In recent decades, there has been an increase in the incidence and prevalence in the world and in the Russian Federation. According to the results of an epidemiological study, an increase in the prevalence and incidence of skin melanoma in the Samara region in 2014–2022 was revealed. An in-depth calculation and analysis of five-year sex and age indicators of the incidence of melanoma of the skin was carried out. It has been established that the incidence rate in women generally prevails over the incidence rate of men in almost every five-year age group. With increasing age (especially in the group of 70 years and older), the incidence becomes higher in both men and women. The fact of a significant increase in the incidence of skin melanoma in 2022 compared to 2014 in young working ages is alarming. The results obtained indicate the need to increase the effectiveness of targeted preventive measures to reduce the prevalence and incidence of skin melanoma, taking into account age and sex characteristics.

The parameters of the enzyme involved in biologically important reactions occurring in an open thermodynamic system — the body of a pregnant woman during the gestational period — were studied. The role of an unfavorable premorbid back ground has been established: infectious diseases, repeated exacerbations of chronic inflammatory processes during prolongation of pregnancy, risk factors for perinatal complications, which causes certain morphofunctional changes in the placenta, form ing placental insufficiency. Pregnant women associated with diseases of the genitouri nary system are more often susceptible to infection. Ultrasound examinations made as part of screening the physiology of the system: mother — placenta — fetus, revealed changes in the structure of the placenta, which indicated a disruption in the relationship between the nascent embryo and the mother’s body, and ultimately manifested itself as violations of compensatory and adaptive mechanisms in the placenta, more pronounced in the sample, burdened by the presence of chronic foci of infection. The dependence of disturbances in the functional ability of the placenta on the level of the enzyme — thermostable alkaline phosphatase specific for it — was revealed. At the same time, a change in the activity of this enzyme was observed, which determined the compensatory capabilities of the provisional organ. In patients with an increased infectious index and placental dysfunction, unstable values of a specific placental enzyme are observed, as evidenced by an unfavorable course of pregnancy, accompanied by the threat of miscar riage and premature birth. These disorders occurred during prolongation of pregnancy and during the process of delivery. A significant decrease in the activity of placental alkaline phosphatase and a decrease in its relationship to alkaline phosphatase were es tablished. The worst indicators reflecting the intrauterine development of the fetus were observed in the sample with placental dysfunction and the risk of infectious complica tions, which was associated with delayed fetal development, and the birth of children with a combination of signs of intrauterine suf fering and hypoxia.

Triggering factors may also include blood transfusions, surgery, bone marrow transplantation, and traumatic injuries to peripheral nerves. understanding the etiology, clinical manifestations and diagnosis of peripheral nerve damage is an important problem in the modern world of medicine.
Mesterséges intelligencia a hitelkockázati modelleknél
Authors: Rajka László , Pollák Zoltán
Published: October 2024

A mesterséges intelligencia által fémjelzett technológiai forradalommal a hitelkockázat kezelésének területén modellek egy új generációja jött létre, amelyeket öszszefoglalóan gépi tanuláson alapuló modelleknek nevezünk. A hitelkockázati modelleknek az elmúlt évtizedekben végbemenő fejlődésében a szakértői rendszerek jelentik a múltat, a hagyományos statisztikai modellek (például a logisztikus regresszió) képviselik a jelent, a gépi tanulási metódusok pedig valószínűsíthetően a jövőt. Jelen tanulmány célja ez utóbbi gépi tanulási modellek egyik legígéretesebb képviselőjének, az XGBoost klasszifikációs algoritmusnak az ismertetése és annak empirikus vizsgálata, hogy a jelenlegi iparági best practice-nek számító hagyományos modellezési módszerekhez képest milyen hatékonyságnövekedés érhető el a gépi tanulási algoritmusok segítségével. Vizsgálatunkban a mesterséges intelligencián alapuló módszertanok közül a Mesterséges Neurális Hálózat (ANN) és az XGBoost-modell egyaránt felülmúlta a logisztikus regressziós megközelítést a klasszifikációs hatékonyság tekintetében. Noha a gépi tanulási módszerek kiváló predikciós képességgel rendelkeznek, hátrányuk, hogy esetükben a döntési modellek értelmezése nehézkesebb hagyományos társaikhoz képest. A mesterséges intelligencián alapuló gépi tanulási módszerek „fekete doboz” jellege miatt a bankoknak jelenleg kevés lehetőségük van azok alkalmazására, ezért javasolnánk a jelenlegi – hagyományos modellekre szabott – szabályok és ajánlások újragondolását olyan módon, hogy az teret adjon a bankoknak a gépi tanulási modellek alkalmazására és ezáltal hitelkockázat-kezelésük hatékonyságának növelésére.
Digitális felkészültség és gazdasági növekedés : A Digitális Gazdaság és Társadalom Index (DESI) pontszám és a GDP összefüggése az európai országokban
Authors: Almeida de Figueiredo Sara
Published: October 2024

A jelen tanulmány a digitális felkészültség és a gazdasági növekedés közötti kapcsolatot vizsgálja az Európai Unióban. A Digitális Gazdaság és Társadalom Indexet (DESI) alkalmazzuk mint átfogó mérőszámot, hogy felmérjük a digitális integráció hatását a gazdasági mutatókra. Részletesen elemezzük az indexet alkotó tényezőket, mint például a humán tőke, az internet-hozzáférés, a digitális technológiák integrációja, a digitális közszolgáltatások, valamint az ellenőrző változókat, beleértve az ipari termelést, a foglalkoztatottság szintjét, az inflációt és a beruházásokat. Így a kutatás segítségével mélységében értjük meg, hogyan függ össze a digitális felkészültség a GDP növekedésével 22 európai országban egy hatéves időszak során. Az eredmények kiemelik a humán tőke és a technológiai integráció szerepét a gazdasági fejlődésben. Rámutatnak, hogy a digitális készségekbe történő befektetés és a digitális technológiák üzleti alkalmazása kulcsfontosságú, növeli a termelékenységet, és elősegíti az innovációt. Ezzel szemben a digitális közszolgáltatások kapcsolata a GDP-növekedéssel kis mértékben negatív, ami azt jelenti, hogy optimalizációra van szükség a vonatkozó gazdasági előnyök minél teljesebb körű kihasználása érdekében. Eredményeink aláhúzzák a digitális felkészültség céljából végrehajtott stratégiai befektetések fontosságát, hogy a digitalizáció elérje azt a szintet, amikor hozzá tud járulni a fenntartható gazdasági növekedéshez, és arra ösztönzi a politikai döntéshozókat, hogy stratégiájukban vegyék figyelembe mind a digitális, mind a hagyományos gazdasági tényezőket. A kutatás pozitívan járul hozzá a digitális átalakulás gazdasági vonatkozásairól folyó diskurzushoz, elősegíti, hogy a politikai döntéshozók, gazdasági szakemberek és üzleti vezetők nagy lépést tegyenek előre a gazdasági ellenállóképesség és prosperitás felé a digitális korban. Másrészt elismeri a DESI-pontszámok korlátait, minthogy ezek csak 2017-től kezdődően léteznek, és annak a lehetőségét, hogy a digitális közszolgáltatásokba történő befektetés hatása késleltetett a gazdaság növekedésére. Ugyanakkor kiemeli, hogy további kutatásra van szükség nagyobb adatmennyiségen ahhoz, hogy teljes mértékben megértsük a digitális felkészültség és a gazdasági fejlődés között fennálló, hosszú távú összefüggéseket.

ETHICAL AND AXIOLOGICAL ASPECT OF PROFESSIONAL TRAINING OF MASTERS IN THE HUMANITIES
Authors: Vynnychuk R. , Kravchenko L.
Published: October 2024

The article investigates the topical scientific and empirical problem of professional training of masters in the humanities at Ukrainian universities based on cultural, personal, and integration paradigms with the use of methodological and technological tools of historical, pedagogical, and modern scientific approaches.
The models and factors of training masters in the humanities at universities throughout the entire period of existence of these institutions are generalized; the concept and contextual and professional model of the system of such training on axiological principles are presented. As a result of a gradual elucidation of the prerequisites and factors of the value dimension of humanitarian education of masters in different models of European universities for the period from the time of their emergence (the lower boundary of the study is the IX century) to the present (the beginning of the XXI century), the essence of the concept of «axisphere of future masters in the humanities» (a set of values of the personality of specialists that determine their activity in teaching and research) is clarified. Their attitude to the world and their self-knowledge in the chosen field and specialty is clarified using analytical and methodological tools of historical and pedagogical general scientific and special pedagogical approaches; the need to develop and implement in practice the educational and research activities of modern universities of the humanities is explained. The technological and methodological support of the proposed model is updated.
It is proved that the tendencies of internationalization, intensification, deepening of international cooperation, and building a context-oriented environment for training masters in the humanities in modern universities based on an integrative educational paradigm contribute to a powerful renewal of teaching, research, and provision of educational services; the values of multiculturalism of the personality of higher education students are determined as significant in the interdisciplinary scientific discourse (philosophy of education, sociology, psychology, pedagogy and education sciences, etc.)
It is concluded that the main results of the study should be used for the further development of the system of professional training of masters in the humanities (historians, philosophers, religious studies, cultural studies, philology) on axiological principles in Ukrainian universities.
METHODOLOGICAL ANALYSIS OF THE ANTHROPOLOGICAL PROBLEMS OF H. SKOVORODA’S PHILOSOPHY IN THE MODERN CONTEXT
Authors: Kravchenko P.
Published: October 2024

The hostilities that have been taking place in Ukraine since 2014 have made socio-political transformations related to the fateful issues of the future of the Ukrainian people and nation and their state-building processes particularly acute. In such circumstances, classical socio-philosophical issues come to the fore, as they allow us to comprehensively understand human social activity, its potential, and internal and external forces, and to assess the importance of the individual as a cultural and creative being. This issue is closely related to the anthropological one in the training of philosophers since future specialists must realize that man is the center of social and socio-political processes, that he is a microcosm in which the entire macrocosm is concentrated, as H. Skovoroda argued. The philosophical symbolism of the thinker’s work is directly related to wisdom, akin to work, seeing the great in the small, revealing the mystery through the symbolic world. This is the way to a happy life. To be a human being is to be a philosopher, says Hryhorii Savych and the fate of each person is inseparable from the fate of the nation, and this unity lies in the world of freedom, which many do not understand, because it requires fighting the whole world on the principles of love, not hatred. This is the classical Ukrainian philosophy founded by H. Skovoroda. Its task is to awaken the main slogans of the Enlightenment (honor and dignity, freedom, justice, solidarity, morality) and to practically direct them to achieve both one’s freedom and the freedom of an open society. The development of such a society in Ukraine is the goal of the modern national state-building process, and the realization of the value principles is the goal of philosophical education.
Future philosophers, studying H. Skovoroda’s creative heritage, can trace the evolution of the human spirit: internally devastated, without certain life guidelines, a person gradually adapts to life in society; overcomes contradictions between the individual and the general, finds a compromise in relations with the environment. Of course, not everyone will be able to successfully go through the path of their spiritual formation, since this process requires a significant strain of internal and external forces, unity and struggle of mind and feelings, worldly wisdom, and a desire to join in finding out the causes of human cruelty and arbitrariness, identifying the sources of humanity in man and society.

Authors: Hrytsai N. , Popeplnytska O.
Published: October 2024

The article is devoted to a research approach implementation in the methodological training of future science teachers. The author emphasizes the need to develop research competence in higher education students majoring in the subject specialty 014.15 Secondary Education (Natural Sciences) and obtaining a professional qualification of a teacher of natural sciences, physics, chemistry, and biology to work in the New Ukrainian School.
The article’s purpose is to reveal the essence of the research competence of future science teachers and the peculiarities of implementing the research approach in their methodological training. It has been established that the research approach involves the organization of the educational process in which learning takes place through research activities. The research competence of future science teachers is interpreted as an integrative quality of a personality that combines motivation for research, methodological knowledge and knowledge of research technologies, research skills, the ability to carry out research activities, organize them with students in teaching science subjects, and evaluate their effectiveness. It is determined that this research competence combines motivational, cognitive, activity-operational, and reflective components. The importance of methodological disciplines in the formation of research competence of future teachers of natural sciences, physics, chemistry, and biology is emphasized. It has been found that the research approach in the methodological training of future teachers requires the use of specific teaching methods and technologies (project, contextual, case technology, research laboratory work). It contributes to the research competence of higher education students development, in particular, their ability to organize students’ research activities in science classes in general secondary education institutions.

Revisão sistemática de literatura sobre a implantação de áreas verdes urbanas como política pública de combate às mudanças climáticas
Authors: Leite Saulo Rocha , Sabonaro Débora Zunkeller
Published: October 2024

O desafio de combater a mudança climática têm impulsionado os governantes a adotarem medidas para regulamentar e promover projetos sustentáveis, além de implementar estratégias mitigadoras e adaptativas. Enquanto isso, o setor privado, ciente de sua responsabilidade está embarcando em uma transição para uma economia de baixo carbono, destacando-se as diretrizes ESG (Environmental, Social and Governance). A elaboração e regulamentação de instrumentos para avançar no combate às mudanças climáticas estão em andamento, com cada setor estruturando ações para efetivamente reduzir as emissões de CO2 na atmosfera. As áreas verdes urbanas surgem como um desses instrumentos, não apenas influenciando a dinâmica atmosférica e o ciclo do carbono, mas também melhorando a qualidade de vida nas cidades, controlando a temperatura, preservando o solo e valorizando o aspecto estético urbano, entre outros benefícios. Este trabalho explora o papel das áreas verdes urbanas como política pública de adaptação e combate às mudanças climáticas, contribuindo para a agenda 2030 proposta pela ONU, especialmente com os ODS 11 - Cidades e Comunidades Sustentáveis e 13 - Ação Contra a Mudança Global do Clima.

Objective. Trunk compensations do not allow the upper limb to use its full potential to perform functional activities. Therefore, the objective of this study was analyzing the effects of movement retention and induction therapy (TRIM) with trunk and upper limb stabilization in hemiparetic patients following a stroke. Method. This was a clinical pilot study with 18 individuals with sequelae from a stroke were randomly assigned to one of three groups: a control group (CG), an experimental TRIM group without trunk restriction (GET), and an experimental TRIM group with trunk restriction (GETT). The GET and GETT groups underwent TRIM therapy based on the Shaping protocol for ten consecutive sessions, lasting 1h each, over 2 weeks. Fugl-Meyer Sensory-Motor Function Assessment Scale (FAS), the Upper Extremity Activity Inventory (MAL), surface electromyography (EMG) of the elbow flexors, extensors, and superficial wrist flexors, as well as goniometric measurements of the upper limb were utilized for evaluation. Results. Significant differences were observed over time in the GET and GETT groups for the total scores on the FAS and MAL scales, as well as in the range of motion for shoulder flexion (p<0.05). No significant differences were found for the EMG variables. Conclusion. TRIM combined with trunk stabilization did not exhibit any significant effects on functional, sensorimotor activities, or EMG and range of motion variables when comparing different groups.

Deposition of palladium hexafluoroacetylacetonate on porous matrices by adsorption in a supercritical CO2
Authors: Костенко М.О. , Зуев Я.И. , Новиков К.С. , Паренаго О.О.
Published: October 2024

В работе рассматривается адсорбционное нанесение гексафторацетилацетоната палладия Pd(hfa)2 на пористые носители (γ-Al2O3 и сверхсшитый полистирол) в среде сверхкритического СО2. Изучены условия перехода системы Pd(hfa)2/ СО2 в однофазную область. Показано, что благодаря достаточно высокой растворимости выбранного соединения палладия в СО2, его нанесение возможно проводить при относительно невысоких давлениях (- 8,5 МПа) в системе. Адсорбция Pd(hfa)2 на выбранных носителях хорошо описывается уравнением Ленгмюра. Повышение давления в системе в изотермических условиях негативно влияет на количество адсорбированного прекурсора, за счет адсорбции СО2 и смещения распределения в системе. Рост температуры в системе в изохорных условиях приводит к увеличению предельной адсорбции.

The paper discusses the adsorption of palladium hexafluoroacetylacetonate (Pd(hfa)2) onto porous carriers (γ-Al2O3 and hypercrosslinked polystyrene) in supercritical CO2 to obtain supported palladium catalysts. The transition conditions of the Pd(hfa 2/CO2 system into the single-phase region have been studied. It is shown that due to the sufficiently high solubility of the palladium precursor in CO2, its deposition can be carried out at relatively low pressures in the system (- 8,5 MPa). The adsorption of Pd(hfa)2 on chosen carriers can be well characterized by the Langmuir equation. The system pressure increase under isothermal conditions negatively affects the amount of adsorbed precursor, due to the competitive CO2 adsorption and the distribution shift in the system. The system temperature increase under isochoric conditions leads to an increase in the adsorption limit.

A képek belső látása
Authors: Sinka Péter
Published: October 2024

Ebben az írásban egy saját tapasztalaton alapuló élményről számolok be: egy kiállítás és az ott bemutatott képek narratív leírásával, valamint a különféle érzékszervek bevonásával vak emberek a gondolati térben „látták” a képeket és éltek át esztétikai élményt. Ennek megértéséhez először kifejtésre kerülnek Csőke Anna Mária narrátor képleíró ismertetőjének műelemző szempontjai, illetve a különféle ingerek képi imaginációra gyakorolt hatásai. Majd olyan kérdések kerülnek előtérbe, hogy a gondolti térben létrejövő képnek mennyi köze lehet a fizikai térben lévő képhez, vagy a mű „aurája” (esetleg annak hiánya) és a környezet milyen hatással van a képi élmény befogadására. Ezután, ennek ismeretében arra kérdésre keresem a választ, hogy képi információ feldolgozásának ezen módja a vizuális nevelés-oktatásban hogyan alkalmazható a művészeti és a társadalmi érzékenység formálásának szolgálatában. Egy vizuálisan nem megtapasztalt, de narratív módon leírt kép a különféle ingerek bevonásával együtt egy pszeudo képet alkot, mely gondolati térben jön létre, ennek leképezése, azaz a fizikai térben való reprodukálása pedig különleges vizuális alkotói gyakorlat lehet diákok számára. Ezen gyakorlat pedig a vizuális memóriát erősíti, inspirálóan hat a képalkotó- és kifejezőképességre, az érzékszervekre való tudatos koncentrációra, valamit fejleszti a vizuális fantáziát, az asszociációs készséget.
Tanulmány és beszélgetés Uray-Szépfalvi Ágnessel, Munkácsy-díjas festőművésszel

Published: October 2024

Uray-Szépfalvi Ágnes festőművész idén, 2024-ben Munkácsy-díjban részesült „kiemelkedő képzőművészeti tevékenység-ért”. Ennek és „rossz” rajzainak apropóján áttekintettük Ágnes közel negyvenéves művészeti pályáját, azaz a tanulmányairól, az egyéni és csoportos tárlatairól, a karrierjének csúcsairól és mélypontjairól fellelhető információkat személyes beszélgetéssel egészítettük ki és illusztráltuk. Arra következtettünk, hogy a festőnő, azáltal, hogy visszatért az alapokhoz, jelenleg a művészi útját keresi eljövendő képeinek megalkotásához. Végül megállapítottuk, hogy az általa a posztgraduális képzés során kutatott „Sprezzaturá”-val – azaz a tanult vagy tanulmányozott nemtörődömséggel –, amely csak az igazán nagy művészeknek adatott meg, Ágnes művészete és élettere is jellemezhető.

Government regulations on Islamic education in Indonesia have provided significant clarity and fulfilled educational needs within a developing society. These regulations demonstrate democratic, cultural, and adaptable qualities in the legal framework of Islamic education. However, challenges remain in achieving parity between Islamic and general education policies. This research employed a literature review approach, analyzing data from books, scientific articles, and research reports. A comparative and historical analysis was conducted to assess the impact of government policies on Islamic education. The findings reveal three key outcomes: (1) Government policies have shaped Islamic education to help students understand and practice their religious teachings across various levels of general education; (2) The Ministry of Religion has been granted autonomy to determine Islamic education curriculum policies; and (3) Political efforts to equalize the status of Islamic education with general education have encountered significant challenges, hindering policy development. The research highlights the ongoing struggle to integrate Islamic education within the broader educational system, which continues to present obstacles for policymakers. Despite these challenges, the autonomy granted to the Ministry of Religion marks progress in shaping the curriculum according to Islamic values. The study provides valuable insights for policymakers and stakeholders, offering guidance on improving Islamic education policies in Indonesia. Further efforts are necessary to address the political challenges that affect the development and implementation of Islamic education laws.
