The aim: of our work was investigation of dystrophy in periodontal tissues and an attempt to establish the correlation between dystrophy in the periodontium and presence of intestinal disbacteriosis.
Materials and methods: Clinical-radiological examination was carried out in 146 patients with generalized periodontal pathology at the age from 26 to 59 years old. Among them in 92 persons generalized periodontitis was diagnosed and in 54 – periodontosis. The first stage of heaviness of the pathological process in the periodontium was revealed in 50 patients with generalized periodontitis and 28 persons with periodontosis. Other patients suffered from heavier forms of periodontal pathology (II and III stages), 42 persons with generalized periodontitis and 28 persons with periodontosis accordingly. Bacteriological analysis of feces for disbacteriosis was carried out in all patients.
Results: Changes in the physiological contour of the gums (that is macro relief of marginal periodontium) were found in the majority of examined patients. Because of the development of pathological gingival contour and recession of the gums, 72,5% of examined patients suffered from root denudation and different pathological conditions of roots cement structure – pigmentation, demineralization, wedge-shaped defects, caries. According to our clinical investigations it was found out that in majority of patients (83%) both inflammatory and dystophic changes were present, only 17% of patients had purely atrophic process in the periodontium without inflammation. In patients with GP and periodontosis, in whom dystrophic changes were accompanied by inflammation, clinical appearance was more expressed with redness, bleeding and suppuration from the pockets, thus hiding dystrophic signs.
Conclusions: According to clinical and radiological findings numerous dystrophic changes were found in all structures of the periodontium and teeth of patients with periodontosis and generalized periodontitis. Changes intensify in disease progressing into the II-III stages. In patients with periodontosis clinical- radio¬logical peculiarities of dystrophy were revealed in early stages of disease progression, while in generalized periodontitis dystrophic changes become apparent in late stages of disease. The presence of colon disbacteriosis was established in patients with periodontosis and generalized periodontitis. Disbacteriosis intensifies when diseases progress into II-III stages of heaviness. These data indicates to possible correlation between the development of dystrophic changes in periodontal tissues and the presence of intestinal disbacteriosis.

Published: September 2023

The aim: To analyze the current views on diagnosis and management of infectious mononucleosis in children. The purpose of our work is also a comparative characteristic of the incidence of infectious mononucleosis in Ukraine and the city of Poltava (2006-2022).
Materials and methods: The data of scientific literature have been analyzed, using the bibliosemantic method of study. We used a retrospective analysis of statistical data on the incidence of infectious mononucleosis 2006-2022 and the most frequent cases of infectious pathology in children in the period 2019- 2022, and also conducted an analysis of the percentage of those vaccinated according to the vaccination calendar.
Results: We had an increase in the incidence in 2009, but in subsequent years it was in the range of 23-25.2 per 100.000 children. The incidence of patients diagnosed with infectious mononucleosis per 100.000 of the children population in the Poltava region is one of the lowest in Ukraine, accounting for 8.1 - 10.1% over the past 3 years, which can be explained by the decrease in visits by parents and their children to the hospital to avoid contact with patients with the coronavirus disease and the fact that our region also had rather lower rates of children with Covid-19 compared in Ukraine.
Conclusions: the situation with the spread of infectious mononucleosis in children in Ukraine is such that it causes concern, and when comparing the incidence in 2009 and 2022, the authors noted an increase in the overall incidence of this nosology by 5%.

Authors: Makarov Vasyli B. , Dedukh Ninel V. , Nikolchenko Olga A.
Published: September 2023

The aim: To study the osseointegrative properties of titanium and tantalum implants with different surface structures in animal experiments.
Materials and methods: The histological and morphometric study was carried out on 60 male white rats after titanium implants with different surface structures made by 3D printed technology were inserted in the distal femur bone: presented by the multilayered layers of interlacing pores of 300 microns (series 1); rough (> 2 microns) (series 2); and tantalum implants with 300 microns pores and 80% porosity (series 3) as control material.
Results: On the 30 days we found statistically significant differences in the bone-implant contact rate between the 2nd experiment series (44.77 ± 1.86)% and 1st (59.91 ± 2.86)% (p=0.000047) and 3rd (53.89 ± 2.11)% (р=0.000065), on the 90 days between the 2nd experiment series (51.26 ± 2.7)% and 1st (66.84 ± 2.63)% (p=0.000187) and 3rd (70.35 ± 4.32)% (p=0.000349). There was a difference between the indices of the bone-implant volume at day 90 between the 1st (48.43 ± 2.2)% and 2nd (36.88 ± 2.56)% series (p=0.000919), between the 2nd and 3rd series (51.2 ± 3.06)% (p=0.000107). There were no significant differences between the studied indices in the 1st and 3rd series of the experiment.
Conclusions: Titanium implants with multilayered interlaced pore layers of 300 microns and tantalum with 300 microns pore size and 80% porosity may be promising. Rough-surface titanium also has osseointegrative qualities, but they are lower compared to other materials.

Published: September 2023

The aim: To examine the morphology regarding the term placentas in pregnancies with threatened abortion with bleeding in the first trimester
Materials and methods: 118 term placentas were selected, of which 40 placentas with the physiological course of pregnancy. 78 placentas were from women with threatened abortion with bleeding in the first trimester, of which 37 patients received hormonal therapy (group I), 41 women were prescribed symptomatic therapy (group II). Placentas were investigatedaccording to the protocol, which includes organometric, macroscopic and microscopic studies.
Results: In the placentas of group II is a significant increase of the area of terminal villi compared due to the stroma against the background of a deficit of fetal capillaries. In group I have revealed that the specific weight of the vascular bed of the terminal villi was 1.5 times higher compared to the control (Р=0.031) and 2.7 times higher than the group II (Р=0.022) and dominates the share of the stroma. The weight of the epithelium of the terminal villi in all groups is approximately the same (Р=0.042), but the ratio of the epithelium to the stroma is higher in the group I (0.63) than in the control (0.43).
Conclusions: In women with a pathological course of the first trimester of pregnancy the compensatory mechanisms in full-term placentas are morphologically represented by an increase in the number of terminal villi, syncytio-capillary membranes, intensification of angiogenesis. In the placentas of women who received hormonal therapy adaptive reactions are most effective and able to compensate for the gestational immaturity of the chorion.

Published: September 2023

The aim: Establishment of emotional and behavioral ways of student response to the coronavirus pandemic, the assessment of dominant coping strategies, and the prevalence of neurotic states and stress among students.
Materials and methods: The research used a specially developed questionnaire and a block of psychodiagnostic methods for diagnosing manifestations of neurotic conditions in students (Clinical questionnaire for the detection and assessment of neurotic conditions by K.K. Yakhin, D.M. Mendelevich), the level of psychological stress (Psychological Stress Scale PSM-25) and basic coping strategies (R. Lazarus’ “Coping Strategies” questionnaire). The sample consisted of 213 respondents (119 girls, and 94 boys).
Results: Among Ukrainian students, the dominant reactions to the pandemic are depressive disorders, anxiety, and fears, a third of students self-reported autonomic disorders. The stress level is moderate. Girls react to the pandemic situation with more serious mental health disorders compared to boys. The use of all coping strategies was recorded at a high level of stress, which suggests that students have already exhausted their adaptation potential and are maladapted to the current conditions.
Conclusions: The study confirms the negative impact of the pandemic on the mental health of young people. The relationship between the type of response to the pandemic and the severity of neurotic disorders and stress was established. Available mental resources to cope with a difficult situation are exhausted, so students prefer to avoid and ignore stressful information. This creates the need for psychological support and educational activities regarding healthcare techniques.

The aim: To present and share our experience in the treatment of pancreatoragia which could help to prevent pancreatoragia in patients with chronic pan¬creatitis in the pre- and postoperative period.
Materials and methods: Surgical treatment of complicated chronic pancreatitis (CP) was performed on 249 patients in the surgical clinic of the medical faculty №2 of National Pirogov Memorial Medical University of Vinnytsia during 2000 - 2021. Pancreatorrhagia occurred in 6 (2.4%) patients, group A – 3 (1.2%) - as disease manifestation, group B – 3 (1.2%) – as complication after surgery.
In group A the source of bleeding was the lower pancreato-duodenal artery: 2 (0.8%) had lower pancreaticoduodenal artery aneurysms with bleeding into the cyst, 1 (0.4%) - a year after previously performed pancreato-duodenal resection. In group B pancreatorrhagia developed in 3 (1.2%) patients after the Frey-Izbitsky local resection of the pancreas: 2 (0.8%) - from pancreato-jejuno anastomosis, 1(0.4%) - from pancreatopleural fistula.
Conclusions: Pancreatoragia, as a manifestation of chronic pancreatitis, occurred in 6 (2.4%) patients. Bleeding occurred as a manifestation of the disease in 3 (1.2%) patients and in 3 (1.2%) patients - in the postoperative period. It is possible to use fibrin or cyanoacrylate glue to filling the defect of the pancreatic duct or to suture vessels in the parenchyma of the pancreas by PDS for the prevention of pancreatoragia in the postoperative period.

The aim: To analyze scientific data on the problems of disorders of bone morphogenesis in children, in particular, non-ossifying fibroma. To analyze modern methods of diagnosis and treatment of this disease in the context of the latest scientific achievements.
Materials and methods: The latest data of scientists from the world’s leading clinics describing various forms of fibrous skeletal lesions in children of differ¬ent ages were analyzed. We examined a boy with fibrous lesions of the cortical layer of the knee joint bones and a girl with a large fibrous focus of the distal femoral metaphysis, which resulted in a closed pathological bone fracture. Surgical treatment, osteosynthesis, marginal resection of the tumor, bone grafting and histological examination were conducted.
Conclusions: Despite numerous studies of this disease, the etiopathogenesis of this disease has not been studied. There are no early symptoms of fibrous bone lesions in children. Diagnosis is possible only when a pathological fracture of the affected bone occurs due to extensive growth of fibrous tissue and a significant decrease in the mechanical strength of the bone. Most cases of recognition of such a disease occur accidentally when performing X-ray examinations for other reasons - bruises, sprains, arthralgias, osteochondropathy, infectious diseases, etc. It is known that boys are more mobile and require more frequent X-ray examinations for limb injuries than girls, so the likelihood of accidental detection of such changes increases significantly. Thus, long-term observations of children with fibrous bone lesions have shown that after 40 years, patients rarely developed malignant tumors - osteogenic sarcoma, fibrosarcoma, malignant fibroma of tubular bones, pelvic bones.
There are no early symptoms of fibrous bone lesions in children. Recognition of such a disease occurs by chance when X-ray examinations are performed for other reasons.

Authors: Danylova Tetiana , Vovk Anatoliy , Hoian Ihor , Kholodynska Svitlana , Honcharenko Kateryna , Ishchenko Olena , Bezhnar Anna
Published: September 2023

The aim: The paper aims to examine the relationship between philosophy and mental health.
Materials and methods: The authors used integrative anthropological approach, interpretive research paradigm, hermeneutical approach. The data collection was carried out using Scopus, Web of Science, PubMed, Google Scholar databases. Research papers were identified according to search terms: “mental health”, “philosophy”, “Ancient philosophy”, “Epicureanism”, “Stoicism”, “Eastern philosophy”, “Buddhism”, “Taoism”, “psychology”, “psychotherapy”, “anxiety”, “depression”, “happiness”, “mindfulness”, “meaning in life”.
Conclusions: Attempts to cope with life challenges, frustration, fear, anxiety, stress should not be isolated endeavors, but they need to be placed in a wider philosophical context, as far as every issue, including mental health issues, has a philosophical perspective at its core. Such experience can cultivate human strength, self-confidence, awareness, empathy. In times of uncertainty, when we do not know where to go, when we do not understand who we are and what is our purpose on earth, philosophy helps us to find our way. In the most difficult times, philosophy acts as a guiding star and consolation reconciling us with what we are unable to change.

Published: September 2023

The aim: The purpose of the article is to identify the essence and causes of collective trauma and reveal its consequences for group identity.
Materials and methods: The authors used an interdisciplinary approach along with the principles of objectivity, tolerance, and impartiality. The analysis of the texts was conducted according to the basic principles of hermeneutics, namely the inexhaustibility of the authentic text and immanent critique. In addition, the method of conceptual and categorical analysis was applied, as well as induction, deduction, generalization, etc. The data collection was carried out using PubMed, Scopus, Google Scholar databases. Research papers were identified according to search terms: “trauma”, “traumatic experience”, “collective trauma”, “traumatization”, “stress”, “historical trauma”, “defeat”, “the Holocaust”, etc.
Conclusions: Collective trauma is a mental wound caused by the direct or indirect traumatic experience – a stressful situation that becomes a source of emo¬tional tension due to an unexpected threat to the life of a group of people. Collective trauma occurs, on the one hand, due to the awareness of helplessness in the face of danger and, on the other hand, due to the excessiveness of traumatic experience, which turns it into the eternal present and destroys identity. Historical traumas arise in the process of conscious exploitation of traumatic experience by political or other leaders in order to achieve emotional unity and group consolidation. Without appropriate processing, they can cause antisocial behavior of the traumatized persons that manifests in seeking revenge. Social partnership can help us to avoid the negative consequences of collective trauma and achieve social consensus.

The influence of information technologies on tourism and recreation activities is studied. The conditions of functioning of the tourist services market in modern conditions are determined. The article shows that the possibilities of the Internet have contributed to the emergence of new ways of doing business. The peculiarities of using SMM marketing for the promotion of tourist services are revealed. The specifics of the use of computer technologies in the fields of hospitality, transport services, tourist mediation, entertainment, etc. are analyzed. The creation and development of the most powerful company in online booking, Booking.com, is shown in historical retrospect. Using the example of the tire manufacturer Michelin, the article identifies how the advertising company turned from the distribution of travel guides into a highly profitable business and became the basis for the development of gastronomic tourism in its modern sense. The advantages of using information technologies for travelers and service providers are considered, including a significant expansion of search and offer possibilities, and choice, as well as significant cost savings in the payment of commissions to intermediaries, advertising, marketing, etc. Cases of abuse by travel service providers are presented. The main obstacle to the development of e-tourism is the low level of cybersecurity. The article notes that all the countries of the world, which have come under the influence of e-tourism, are working in various ways to strengthen the security of consumers. The necessity of conducting a comparative analysis of the benefits and costs of tourist activities for territories is emphasized.
Regional dimension of demographic sustainability of Ukraine in the war conditions
Authors: Teslyuk Roman T.
Published: September 2023

The main features of the Ukraine’s demographic development before the full-scale invasion of Russia on 24.02.2022 have been identified: a constant significant reduction in the population number since 1993, caused primarily by a drop in the birth rate; intensive migration flows dominated by labor emigration; the appearance 1.5 million of internally displaced persons (IDP) since 2014; population aging; spread of depopulation from the east and northeast to the central regions of the country. It is estimated that the existing population of all of Ukraine at the beginning of 2022 was 39.6-40.1 million people, and without the territories occupied in 2014 – 33.5-34 million. The Russian-Ukrainian war became the main factor in the catastrophic aggravation of the demographic crisis in Ukraine and its regions. The war caused tens of thousands of deaths in Ukraine (civilian and military casualties), more than 14 million forced migrants, significant deformations of population structures: demo-reproductive, marriage-family, socio-economic, language-national, confessional, psycho-mental, and others. In addition to an increase in mortality and a decrease in the birth rate, the demographic consequences of the war are significant migration losses, deterioration of health and reduced life expectancy, decrease in economic activity, aggravation risk of social problems of veterans and IDPs reintegration. A demographic macro-zoning scheme has been developed, the criteria of which are the peculiarities of the course of military operations in certain territories, different periods of temporary occupation of Ukrainian territories, the structure of the population of the regions and its dynamics during wartime, the volume of forced migration. The main problems of the demographic development in the selected 5 macro-regions are formulated. The prospects of post-war demographic development and the main directions of socio-demographic policy, which will contribute to strengthening the demographic sustainability in Ukraine, are determined. The main ones are the demographic orientation of state and regional strategies and programs, the creation of conditions for the rapid return of forced migrants from abroad, the promotion of birth rates, the strengthening of the family institution, the socialization and social integration of war veterans, ensuring the competitiveness of older age groups in the labor market.
VFS over the Years: An Efficient Change Log and System Call for Kernel Developers

Published: September 2023

“The Linux Kernel is getting bloated and huge, it’s a problem. Sometimes it's a bit sad that we are definitely not the streamlined, small, hyper-efficient kernel that I envisioned 15 years ago … The kernel is huge and bloated”
– Linus Torvalds, Linuxcon2009 (Roundtable - The Linux Kernel: Straight From the Source). [1]
The Linux Kernel is getting large day by day, both in terms of lines of code and complexity of features and functions. This includes rapid changes in naming conventions of kernel functions, variables and even the flow of data within the code. Moreover, these changes are not well supported by adequate documentation. These issues account to incremental difficulties faced by developers of system code across the globe. This paper is a study of internal working and changes of virtual File System specific code of Linux kernel versions 2.4, 2.6. and 3.0. We have tried to introduce various changes and new addition of several features of the Linux kernel. This survey regarding virtual file system among various kernel versions may play an important role for system developers during system development to gather information about file system in any specific or several kernel versions.
Trace Fossils and Sedimentary Depositional Environment: A Case Study from Early Permian Barakar Formation, Raniganj Basin, India
Authors: - SUDIPTO BANERJEE
Published: September 2023

Behavioral responses of organisms with respect to changing environment have a wide area of research possibility. For a palaeontologist it is a challenge to interpret the organism-sediment interaction from the study of the trace fossils preserved in the ancient rock record. The ethological significance which
is derived out of different intentional or accidental activities of the organisms may be preserved within the rock and is largely controlled by the substrate stability, grain size of the sediments, energy and rate of sedimentation of the driving process, types of nutrients and its supply, salinity, temperature and oxic/sub-oxic/an-oxic conditions etc. So, the viability of this study in sensu stricto depends on the preservation potential of the organism as a whole or in parts or its activities (indirect evidences) on or within the substrate upon which they have survived thousands and millions of years ago. The indirect evidences of the organism’s activities may be its locomotory/respiration/feeding/resting/dwelling/predating traces etc. which have different nomenclature based on their morphological classification. The study area encompassing the major river section of the Barakar, Khudia, Ajoy holds partly enriched and partly impoverished trace fossils within the sedimentary rocks hosting huge reserves of coal. There are several concepts regarding the
depositional setting of the studied basin like formerly interpreted fluvio-lacustrine depositional model to recently reinterpreted fluvio-tide-wave dominated depositional model. Several invertebrate traces have been recorded from the study area namely Planolites, Thalassinoides, Ophiomorpha, Palaeophycus, Cylindrichnus, Diplocraterion which indicates diverse environmental settings ranging from supratidal/intertidal/subtidal to continental shelves whereas other solo/uniform traces observed like Chondrites, Skolithos, Rhizocorallium etc. are indicator of shallow subtidal to marine quite water setting. Here the additional challenges include the lack of ample exposures, weathered exposed rock
sections, inaccessible mine cut sections, absence of body fossils and controversial identification of trace fossils in differential erosive surfaces. This chapter in short has tried to mitigate these problems by the integrated sedimentary and ichnological facies association studies in delineating the
depositional environment of the studied basin.
Feedback: Engaging the Students in Teaching Learning Process
Authors: - Dr. Nidhi , - Dr. Taruna

Ferguson (2011) writes that “Feedback is considered as a vital approach to facilitate students' development as independent learners in order to monitor, evaluate, and regulate their own learning.” When a feedback “feeds-forward,” or provides information about students' assignments and potential performance, it is said to be effective. Student engagement is required for feedback to be useful and successful. However, Price et al. (2011) note that “Student engagement is a difficult process. Students may stop participating at any time, too.” Numerous studies have been conducted in this field, and one of them (Zhang & Hyland, 2018) demonstrates that involvement is necessary to unlock the potential for boosting student learning. Since teachers are the foundation of this process, their involvement in teaching and learning cannot be overlooked. According to Handley et al. (2011) and Lunt & Curran (2010), “It is apparent that teachers play a pivotal role in promoting student engagement with feedback as they can influence learner perceptions, create a facilitative environment, and provide different modes of feedback.” Numerous studies have found that practical strategies can help students interact with feedback and achieve successful learning outcomes. The present paper focuses on the role of feedback that how feedback engages the students in teaching learning process.

Published: September 2023

Over the decades, the removal of heavy metals from aqueous solution using biosorbents such as algae, fungi, yeast, and bacteria has remained a challenging task. This paper explores the Al(III) biosorption efficiency of magnetotactic bacteria (MTB) via a new strain called SUM 123 of Alcaligenes sp. The influence of temperature, pH, initial Al(III) concentration, and adsorbent dosage on the biosorption efficiency of MTB is examined. The achieved optimum conditions for Al(III) ions biosorption in the aqueous solution is demonstrated to be 80 mg/L, 12 g/L biosorbent at 25 ºC with pH 5. In this situation, the isolated bacteria attained the maximal Al(III) loading capacity as much as 15.74 mg Al(III)/g (biomass) with 99.53% adsorption. Furthermore, better fitness of “the equilibrium data was provided by the Langmuir isotherm model compared to the Freundlich model. Again, the feasibility, spontaneous and endothermic nature of the biosorption process at 10-40ºC were validated by the evaluated thermodynamic parameters (ΔGº, ΔHº and ΔSº). A pseudo second-order kinetic model that fitted the kinetic data was also achieved with a correlation coefficient (R2) value of > 0.993. FTIR spectra manifested the involvement of hydroxyl, amide, and amine groups in Al(III) biosorption process.” TGA displayed the existence of Al(III) adsorption on the cell wall. It is established that the SUM 123 biomass assisted biosorption is a prospective cost-effective method for Al(III) recovery from contaminated waters.
