A TERRA EM PANDEMIA: POVOS INDÍGENAS BRASILEIROS	E SUAS (DERRADEIRAS?) INFÂNCIAS
Authors: Tiriba Lea , Profice Christiana C , Schlesinger Miguel T
Published: April 2021

Inscrito no sofrimento da atual pandemia causada pelo coronavírus, este texto traz reflexões sobre relações entre seres humanos e natureza, sobretudo em referência aos povos originários do Brasil, com atenção especial voltada às suas infâncias. Tratamos conceitualmente da dicotomia natureza-humano, própria de nossa cultura ocidental, sob a ótica crítica da ecologia política e na busca de aproximação com teóricos da biofilia e da noção de sociobiodiversidade. A partir da percepção de proximidade entre as visões de mundo de Spinoza e de povos originários brasileiros, afirmamos a necessidade de aprender com os povos indígenas a cuidar das crianças e, simultaneamente, do planeta.

REFORMISMO E EDUCAÇÃO: A ESCALADA ULTRALIBERAL BRASILEIRA E SUAS REPERCUSSÕES EDUCATIVAS
Authors: Da Silva Victor Leandro
Published: April 2021

O cenário recente da política brasileira vem sendo marcado por um forte ímpeto reformista ultraliberal, cujas consequências podem ser percebidas na recentemente aprovada reforma trabalhista. No entanto, para que tal empreitada se efetivasse, foi necessário promover também mudanças no sistema educativo, com vistas a propiciar as condições ideais para o desenvolvimento de tais diretrizes. Dessa forma, o presente texto tem por objetivo discutir de que maneira a educação encontra-se historicamente ligada às transformações do mundo do trabalho, bem com debater os elos que vinculam no Brasil a reforma do ensino médio e as mudanças deletérias dos direitos dos trabalhadores.
DE QUEM É O CORPO QUE COMPÕE A FORÇA DE TRABALHO? REFLEXÕES SOBRE TRABALHADORAS/ES TRANS NO CONTEXTO DA COVID-19
Authors: Augusto Ribeiro Jéssyka Kaline , De Almeida Guilherme
Published: April 2021

Este artigo é parte de um esforço para compor uma análise acerca das condições de vida das trabalhadoras e trabalhadores trans no atual contexto da pandemia da Covid-19. Nesse processo é importante destacar a anterior dificuldade da inserção das travestis, das mulheres transexuais e dos homens transexuais no mercado de trabalho brasileiro. E em contextos de crise do capital, exploração intensa do trabalho e aumento do desemprego, a situação se agrava ainda mais. Com a pandemia da Covid-19 ocorreram mudanças significativas na vida das pessoas trans no Brasil, principalmente entre as mais impactadas pela pobreza, pelo racismo e por outras formas de desigualdade social.

Authors: Kovyazina V. P. , Raikhelson K. L. , Prashnova M. K. , Pazenko E. V. , Palgova L. K. , Kondrashina E. A.
Published: April 2021

Aim. Estimation of the liver steatosis and fibrosis incidence with transient elastography and the controlled attenuation parameter in residents of St. Petersburg.

Materials and methods. A prospective open single-centre population study included history, anthropometric and laboratory data on 318 outpatients aged 24—89 years (mean age 52.6 ± 14.6 years). The degrees of steatosis (assessed with the controlled attenuation parameter as ultrasound amplitude dropdown quantification in liver) and fibrosis were determined with a Fibroscan 502 Touch unit (Echosens, France).

Results. Hepatic steatosis of predominantly high degree was revealed in 44.7%, combined fibrosis and steatosis — in 28%; isolated fibrosis of various stage — in 2.5%, no structural changes — in 24.8% individuals. The growth of body mass index and waist circumference significantly correlated in women with pronounced liver changes. Serum transaminase activity increased with more severe liver changes, being statistically significant for aspartic transaminase only.

Conclusion. A high incidence of primary liver steatosis and fibrosis in residents of St. Petersburg warrants improved diagnostic algorithms and routine preventive measures. Transient elastography with the controlled attenuation parameter estimation provides a convenient non-invasive screening for hepatic fibrosis and steatosis.
Current Potential of Pantoprazole in Treatment and Prevention of Gastrointestinal Diseases
Authors: Sheptulin A. A. , Kardasheva S. S. , Kurbatova A. A.
Published: April 2021

Aim. An outline of the current potential of pantoprazole in treatment and prevention of upper gastrointestinal diseases.

Key points. Pantoprazole is widely applied in gastroesophageal reflux, peptic ulcer disease, Zollinger—Ellison syndrome and for Helicobacter pylori eradication. It minimally inhibits the CYP2C19 isoenzyme involved in the metabolism of many drugs. Pharmacokinetics of pantoprazole conditions a weaker drug interaction compared to other proton pump inhibitors (PPIs), which enables its use for gastrointestinal bleeding prevention in patients receiving dual antiplatelet therapy. The new coronaviral pandemic of COVID-19 urges the selection of PPIs that minimise the drug interference, such as pantoprazole, in therapy and prevention of acid-related upper gastrointestinal diseases. Pantoprazole has a good tolerance and low side effect rate.

Conclusion. Pantoprazole is considered among optimal PPIs for efficacy, safety and adherence on the basis of clinical trials for treatment and prevention of gastrointestinal diseases, systematic reviews and meta-analyses.

Published: April 2021

Aim. Description of the endoscopic and clinical traits of heterotopic gastric mucosa (HGM) observed in cervical oesophagus.

Key points. HGM in proximal oesophagus can be asymptomatic or have various clinical manifestations. A 40-yo female patient consulted a gastroenterologist with complaints of cough and globus sensation. For several years she was visiting an otorhinolaryngologist and psychotherapist, with therapy ineffective. Esophagogastroduodenoscopy (EGDS) at the last visit revealed several foci of HGM in cervical oesophagus of 1.2 x 0.8 cm maximal size. The patient was prescribed a combined prokinetic — proton pump inhibitor therapy, which relieved the symptoms. EGDS in a 21-yo patient without active complaints revealed a 2 cm-wide HGM of 4/5 cervical oesophageal lining with acidproducing zones.

Conclusion. Two different scenarios of cervical oesophageal HGM are described, the first one manifested with laryngopharyngeal reflux, and the second devoid of clinical manifestations despite a large heterotopic site.
Teaching Practice Online: Challenges in Japan, India and Kenya Under Pandemic
Authors: Hansson Per-Olof
Published: April 2021

The coronavirus pandemic affected the whole world in 2020, with high pressure on the health sector, many deaths, reduced business activity, rising unemployment rates, travel restrictions and social distancing. These developments have had severe consequences for all areas of every society around the globe. This also includes education. In many countries, primary and secondary pupils and university students alike were sent home as schools and universities closed abruptly as part of efforts to control the spread of the virus. As teaching moved online, learners and teachers were unprepared for the new situation, which posed a unique set of challenges. In this context, trainee teachers at a Swedish university were encouraged to support online teaching at schools in Japan, India and Kenya. The purpose of the digital internship was threefold: to continue the trainees’ teaching placements in the absence of opportunities for in-class teaching; to provide an opportunity for trainee teachers to develop their own competence in online teaching; and to assist the foreign schools in the challenging task of delivering online classes. This article aims to investigate the challenges faced by pupils in Japanese, Indian and Kenyan schools and by 27 Swedish trainee teachers during this project. Data collection consisted of interviews, an online questionnaire, lesson observations, assessment forms, and reports given by trainees. The main challenges identified through our findings included internet access in host countries, the use of a teacher-centred approach to learning, and difficulty for trainees to relate to the pupils’ life conditions. However, we conclude that the trainee teachers increased their global awareness through a climate-friendly alternative to the traditional teaching placement abroad.
Motivating Online Learning through Project-Based Learning During the 2020 COVID-19 Pandemic
Authors: Hira Avneet , Anderson Emma
Published: April 2021

The transition of traditional schooling to online learning during the COVID-19 pandemic disrupted formal school education. Though at home, teachers and students continued teaching and learning in socially distant ways using online technologies. From various teacher surveys, only about 60% of students in the United States regularly engaged with learning activities. Teachers and parents also expressed a significant need for help to keep students motivated and engaged in learning activities. During the pandemic, online learning left teachers and parents needing support for learning activities that motivate and engage students. Project-based learning is an increasingly popular pedagogical practice centered around students working collaboratively on projects while the teacher facilitates learning activities and progression. Project-based learning embodies several factors considered central to motivation in online learning. In this paper, we inquire how this approach presents itself as a candidate for learning during the pandemic when considering students’ motivation to learn through online learning experiences. We construct a conceptual framework informed by motivational theories that share core tenets with this form of learning and use the framework to analyze interviews of 11 teachers from 4 schools that taught with a project-based learning approach before the pandemic and transitioned to teaching, using it online, in the Spring of 2020. From our analyses of the teachers’ narratives, we discuss teaching aspects of the approach that lend themselves well to online teaching, elements that the teachers believe are missing, and how educators might cater to these missing aspects with a focus on student motivation to learn.

Published: April 2021

In May 2020, the first outbreak of rabbit viral hemorrhagic disease
(RHD) caused by rabbit hemorrhagic disease virus type 2 (GI.2) occurred
in Sichuan, China. The acute onset and short disease course resulted in
rabbit mortalities as high as 42.86%. Currently, basic research on the
etiology and genetic characteristics of GI.2 is lacking in China.
Pathological changes in various tissues from infected rabbits were
investigated, and the viral genome was characterized. This study used
RT-PCR, histopathology, scanning electron microscopy, and whole genome
sequencing analysis to identify the pathogen in samples from infected
rabbits that had died. RT-PCR identified the presence of GI.2. The
histopathology revealed liver cell necrosis and hemorrhaging into lung
alveoli. Electron microscopy demonstrated spherical GI.2 particles that
were 40 nm in diameter with an isometric interior. The gene sequence
length of the isolate was 7,464 bp and termed GI.2/CN/SC-04. The
phylogenetic analysis of the GI.2 genotype showed that the strain from
GI.2/CN/SC-04 clustered into a separate group compared to the isolate
from China (MT586027.1). Phylogenetic analysis based on whole sequences
and showed that GI.2/CN/SC-04 strains were identical and clustered with
other strains of GI.2 circulating globally. The results of recombination
analysis showed that GI.2/CN/SC-04 was recombined from MT586027.1 strain
(main parent strain) and MN90145.1(secondary parent strain), and both
the two recombination breakpoints 2858-5137nt. This was the study to
report that GI.2 had been isolated in China, to characterise the full
genome sequence and provide phylogenetic insights into the origin of
this exotic incursion. development.
Regularity, Asymptotic Solutions and Travelling Waves analysis in a porous medium system to model the interaction between invasive and invaded species
Authors: Díaz José , Naranjo Antonio
Published: April 2021

This work provides an analytical approach to characterize and determine
solutions to a porous medium system of equations with views in
applications to invasive-invaded biological dynamics. Firstly, the
existence and uniqueness of solutions are proved. Afterwards, profiles
of solutions are obtained making use of the selfsimilar structure that
permits to show the existence of a diffusive front. The solutions are
then studied within the Travelling Waves (TW) domain showing the
existence of potential and exponential profiles in the stable connection
that converges to the stationary solutions in which the invasive specie
predominates. The TW profiles are shown to exist based on the geometry
perturbation theory together with an analytical-topological argument in
the phase plane. The finding of an exponential decaying rate (related
with the advection and diffusion parameters) in the invaded specie TW is
not trivial in the non-linear diffusion case and reflects the existence
of a TW trajectory governed by the invaded specie runaway (in the
direction of the advection) and the diffusion (acting along a finite
speed front or support).

Published: April 2021

In December 2019, the novel coronavirus disease 2019 (COVID-19) emerged
in China and spread rapidly around the world, resulting in a pandemic
declared by the World Health Organization in March 2020. The disease has
affected more than 11 million people in Brazil, with more than 265.000
deaths to date, as we are now facing a second wave of infections.
Regarding medical assistance and training, it turned out to be a great
challenge, since - among other things - many residents were relocated to
respiratory units to treat patients with COVID-19. Even though the
residency programs situation has become chaotic all around the world and
the activities in almost all specialties nearly stopped (especially in
surgical specialties), the need to reinvent the way of teaching was the
best concern. Worldwide the “webinars fever” was an impulse to try new
strategies to fulfill the gaps of knowledge of these future specialists.
It is crucial to call to the responsibility put on medical training
institutions to prepare these new professionals according the principles
of evidence-based medicine, surgical proficiency and patient safety.

Lagrange multiplier characterizations of constrained best approximation with nonsmooth nonconvex constraints
Authors: Mohebi H.
Published: April 2021

In this paper, we consider the constraint set K := {x ? Rn : gj(x)? 0,? j =
1,2,...,m} of inequalities with nonsmooth nonconvex constraint
functions gj : Rn ? R (j = 1,2,...,m).We show that under Abadie?s
constraint qualification the ?perturbation property? of the best
approximation to any x in Rn from a convex set ?K := C ? K is characterized
by the strong conical hull intersection property (strong CHIP) of C and K,
where C is an arbitrary non-empty closed convex subset of Rn: By using the
idea of tangential subdifferential and a non-smooth version of Abadie?s
constraint qualification, we do this by first proving a dual cone
characterization of the constraint set K. Moreover, we present sufficient
conditions for which the strong CHIP property holds. In particular, when the
set ?K is closed and convex, we show that the Lagrange multiplier
characterizations of constrained best approximation holds under a non-smooth
version of Abadie?s constraint qualification. The obtained results extend
many corresponding results in the context of constrained best approximation.
Several examples are provided to clarify the results.

Political clientelism in Serbian media - the case of the Tanjug news agency
Authors: Milinkov Smiljana , Gruhonjic Dinko
Published: April 2021

The paper problematizes the presence of political clientelism in the media in
the Republic of Serbia. The aim of this research is to point out the
examples of establishing mechanisms of clientelistic practice in the media,
using the News agency Tanjug as an example. Three analytical categories,
which are relevant for perceiving the problem of clientelism, have been
included: regulatory framework, financial allocations from the state budget
and the reporting of the news agency Tanjug. The results of the research
show that the illegal functioning, the unsolved ownership issue,
non-transparent financing and unprofessional reporting are characteristics
of the media work of Tanjug agency. According to the law, the former state
agency was scheduled to stop work by the end of 2015. However, Tanjug still,
with unclear legal status and significant financial help from the state,
publishes information, some of which were proven to be disinformation. The
analysis of examples of unobjective and unprofessional reporting points out
to the ignoring of public interest, in order to satisfy the particular
interest of the governing political structure, which financially makes
Tanjug?s functioning possible, in an illegal manner. This case represents a
closed circle of interrelationships on the relation politics-economy-media,
through which clientelism is defined, using quid pro quo practice.
Representation of Women in Popular Indian Movies : An Analysis of English Vinglish and Heroine
Authors: OK Auju
Published: April 2021

Male supremacy and patriarchy has become two clichéd words, but it is a fact that these two words define almost all societies in the world. Indian society is no different from this, in fact this is where these two words fit in smoothly. This is reflected in our literature, art and movies too. My enquiry here is about how do the preconceived notions about feminity find their way into popular movies. The article analyzes two popular Hindi movies: English Vinglish and Heroine. These two movies portray two women who are very different from each other ; a house wife and an actress. But many a times these two women are one and the same in terms of the attitude of the society towards them. Therefore the paper intends to reveal the double standards and hypocrisy of Indian society.

Authors: Pratama I Wayan Pio , Kesiman Made Windu Antara , Gunadi I Gede Aris
Published: April 2021

The frequency band method is popular in signal processing; this method separates EEG signals into five bands of frequency. Besides the frequency band, the recent research show PCA method gives a good result to classify digits number from EEG signal. Even PCA give a good accuracy to classify digit number from EEG signal, but there are no research shows which one yielded better accuracy between PCA and frequency band to classify digit number from EEG signals. This paper presents the comparison between those methods using secondary data from MindBigData (MDB). The result shows that the frequency band and PCA achieve 9% and 12,5% on average accuracy with the EPOC dataset. The paired Wilcoxon test produces a significant difference in accuracy between methods in the digit classification problem. Experiment with Muse dataset provides 31% accuracy with frequency band method and 24,8% with PCA method. The result is competitive compared to other experiments to classify digit numbers from EEG signals. In conclusion, there is no winner between the two methods since no method fits both datasets used in this research.

Authors: Al Kautsar Rachmad Jibril , Utaminingrum Fitri , Budi Agung Setia
Published: April 2021

Indonesian citizens who use motorized vehicles are increasing every year. Every motorcyclist in Indonesia must wear a helmet when riding a motorcycle. Even though there are rules that require motorbike riders to wear helmets, there are still many motorists who disobey the rules. To overcome this, police officers have carried out various operations (such as traffic operation, warning, etc.). This is not effective because of the number of police officers available, and the probability of police officers make a mistake when detecting violations that might be caused due to fatigue. This study asks the system to detect motorcyclists who do not wear helmets through a surveillance camera. Referring to this reason, the Circular Hough Transform (CHT), Histogram of Oriented Gradient (HOG), and K-Nearest Neighbor (KNN) are used. Testing was done by using images taken from surveillance cameras divided into 200 training data and 40 testing data obtained an accuracy rate of 82.5%.

Individual recognition using biometric technology can be utilized in creating security systems that are important in modern life. The individuals recognition in hospitals generally done by conventional system so it makes more time in taking identity. A newborn baby will proceed an identity tagging after birth process is complete. This identity using a bracelet filled with names and ink stamps on paper that will be prone to damage or crime. The solution is to store the baby's identity data digitally and carry out the baby's identification process. This system can increase safety and efficiency in storing a baby's footprint image. The implementation of baby's footprint image identification starting from the acquisition of baby's footprint image, preprocessing such as selecting ROI size baby's footprint object, feature extraction using wavelet method and classification process using K-Nearest Neighbor (K-NN) method because this method has been widely used in several studies of biometric identification systems. The test data came from 30 classes with 180 images test right and left baby's footprint. The identification results using 200x500 size ROI with level 4 wavelet decomposition get recognition results with an accuracy of 99.30%, 90.17% precision, and 89.44% recall with a test computation time of 8.0370 seconds.

Published: April 2021

This study design a system prototype to control a mouse cursor's movement on a computer using an electrooculogram (EOG) signal. The EOG signal generated from eye movement was processed utilizing a microcontroller with an analog to the digital conversion process, which communicates with the computer through a USB port. The signal was decomposed using continuous wavelet transform (CWT), followed by feature extraction processes using statistic calculation, and then classified using K-Nearest Neighbors (k-NN) to decide the movement and direction of the mouse cursor. The test was carried out with 110 EOG signals then separated, 0.5 as training data and 0.5 as test data with eight categories of directional movement patterns, including up, bottom, right, left, top right, top left, bottom right bottom left. The highest accuracy that can be achieved using CWT-bump and kurtosis is 100%, while the time needed to translate the eye movement to the cursor movement is 1.9792 seconds. It is hoped that the proposed system can help assistive devices, particularly for Amyotrophic Lateral Sclerosis (ALS) sufferers.

On the basis of a multivariate analysis of literature data, various pathogenetic mechanisms of enteric dysfunctions caused by morphological and structural changes in the wall of the small intestine, violations of its local defense mechanisms are described. The essence of the modern concept of the pathogenesis of enteral insufficiency – enteral distress syndrome (EDS) according to the literature is presented. According to new views, EDS is a combination of various pathogenetic mechanisms that are formed as a result of dysregulation and destabilization of biological membranes of tissue structures of the intestinal wall (especially its mucous membrane) and a violation of the functional and metabolic status of the intestine, developing in acute surgical diseases of the abdominal organs. Recognition of the validity of the concept will allow unifying the terminology and creating more evidence-based and generally accepted teaching about the nature of EIS.

Transcatheter arterial chemoembolization of hepatocellular carcinoma on liver cirrhosis in patients awaiting liver transplantation OBJECTIVE. To evaluate the role of TACE as a method of neoadjuvant antitumor therapy of HCC before LT.METHODS AND MATERIALS. From January 1998 to April 2020, we performed 245 OLTs in 229 patients, among them in 25 (10.2 %) for HCC associated with LC. We analyzed treatment results of 16 patients who received 49 TACE sessions as neoadjuvant therapy. 10 (62.5 %) patients fell under Milan criteria, 6 (37.5 %) – beyond them. According to the Child – Pugh score of LC, two (12.5 %) patients matched A stage, 12 (75 %) – B stage, two (12.5 %) – C stage. According to the BCLC (Barcelona Clinic Liver Cancer) staging system, 10 patients matched A1–A4stage and 6 – B stage. Totally, we performed 49 TACE sessions, both classical with lipiodol and hemostatic sponge, and with drug-eluting beads from 1 to 7 (on average 3) times. In all cases Doxorubicin was used.RESULTS. Technical success was 100 %. There were no complications. We performed RFA in three patients as an adjunct, in two patients – laparoscopic RFA-assisted atypical liver resection and in one patient – sequential resection and RFA. According to the m-Recist criteria, a complete response was observed in 6 (37.5 %), partial – in 7 (43.75 %), and stabilization – in 3 (18.75 %) patients. It was possible to achieve a tumor response to the treatment in 4 patients and return them to the Milan criteria. LT was performed in all 16 patients, among them – 14 (87.5 %) within the Milan criteria. The waiting periods for LT from the beginning of TACE were from 2 to 30 (on average 12.5) months. According to the histological studies, in 13 (81 %) patients, total and subtotal necrosis of HCC was revealed in excised organs.CONCLUSION. The results of the performed study indicate that neoadjuvant TACE delays the growth of HCC masses and prolongs (up to 30 months) a safe waiting period for the donor liver.

RELEVANCE. Pathological tortuosity of the carotid artery and thrombotic occlusion of the intracranial segment of the carotid artery, critical subostial stenosis are the main causes of tandem lesions in patients with intracranial cerebral artery occlusion. Proximal occlusion may prevent intracranial endovascular access to distal tandem occlusion and increase the risk of endovascular complications.The OBJECTIVE was to evaluate technical and functional results of the hybrid technologies used in treatment of a patient with tandem damage of proximal and distal segments of the carotid basin in the acute period of ischemic stroke.CLINICAL OBSERVATION. The result of the intervention was a change in stroke severity by comparing scores on the national Institutes of Health Stroke Scale (nIHSS) after a hybrid intervention – primary reconstruction of the left internal carotid artery with pronounced pathological tortuosity in the extracranial segment and thrombectomy from the tandem M1 occlusion of the left medial artery segment in a patient with ischemic stroke in the left carotid pool in the acute period. A rare clinical observation is presented.

Aotric esophageal fistula: etiopathogenesis and diagnostics (review of literature)
Authors: Muslimov R. Sh. , Danielyan Sh. N. , Popova I. E. , Chernaya N. R.
Published: April 2021

Aortic esophageal fistula (AEF) is a rare but extremely life-threatening condition requiring immediate surgical treatment. The mortality rate among such patients may exceed 60 %, including after surgical treatment. Etiological and pathogenetic mechanisms of AEF are complex and various, but in most cases, they are associated with chronic aortic diseases. The second group of etiological factors of AEF includes trauma of esophagus wall by foreign bodies, malignant neoplasms of the esophagus or mediastinum. AEF may also occur as a result of surgical interventions on the aorta and esophagus. The difficulties of early diagnosis are primarily associated with non-specific clinical manifestations of AEF and the lack of unified protocol for the examination of patients with the first-time upper gastrointestinal tract bleeding. The described reasons in some cases can lead to an inaccurate diagnosis, which entails a loss of time. Among the instrumental diagnostic methods, the most informative is the combination of esophagogastroduodenoscopy and computed tomography of the chest with intravenous contrast enhancement. Each of these methods has its advantages and disadvantages, and allows to identify a number of direct and indirect signs of pathological communication between the aorta and the esophagus.

Published: April 2021

Summary. The purpose of the study is to reveal the activities of credit unions in Drohobych region in the interwar period, to show their role in the economic protection of the Ukrainian population of Galicia in interwar Poland. The research methodology is based on the principles of historicism, systematicity, scientificity, authorial objectivity, as well as the use of general scientific and special-historical methods. The scientific novelty lies in the study of the development of credit cooperation in Drohobych in the 1920‒1930’s. Conclusions. An important place in the cooperative movement of Eastern Galicia in the interwar period belonged to credit cooperatives. In 1938, there were 25 credit cooperatives of Raiffeisen type (rural associations) and Ukrainian banks (Schulze-Delich city cooperatives) in Drohobych region, which were united around Central Bank (Central Cooperative Bank of "Krai Credit Union"). The capital of these institutions consisted of shares of members and contributions of the population. Credit cooperation protected Ukrainians, increased their solvency and economic independence, national consciousness. The main financial institution of the Ukrainian credit cooperative was Central Bank. With well-developed cooperation, Ukrainians could work effectively even under unfavourable conditions and hostility from the Polish occupation regime. The cooperation protected not only the material but also the spiritual needs of Ukrainian citizens, it was a natural manifestation of social and economic self-organization of the people, a source of its cultural self-development. The financial and credit system contributed to the development of cooperation through the organization of affordable credit for the population, the facilitation of mutual relations between national organizations and the strengthening of the legal status of cooperation.

Published: April 2021

Summary. The purpose of the research is to find out aspects of the religious function of male monastic communities of the Eparchy of Lviv (Orthodox and Union) in the local environment at the end of the XVI ‒ first quarter of the XVIII century. The methodology of the research is based on the principles of historicism, interdisciplinarity. Methods inherent for the study history of local social groups are used. The scientific novelty is in an attempt to study the religious function of monasteries in the Eparchy of Lviv, with the involvement of little-known and unpublished sources. Conclusions: among the most important aspects of religious activity of the monasteries of the Eparchy of Lviv was pastoral work, which was uncommon during the period under study. The pastorate of monks in parishes was initiated by church hierarchs or the founders of the parish, less often by the parishioners themselves. An important religious function of monastic communities was funeral services, which were held in monasteries at the request of the faithful inscribed in commemoration books. On the example of Pidhorodyshche monastery commemoration book, it can be stated that small monasteries were popular mainly with peasants or clergy from nearby settlements, to a lesser extent with burghers or gentry. The important role of monasticism in the religious consciousness of various classes of early modern society is confirmed by testamentary gifts in wills for monasteries. The personal religiosity of specific individuals played a significant role in their making. The nobility and burghers often chose monasteries as the place of their burial. Both family ties to monasteries and personal religiosity were decisive in this choice. An important place in the religious consciousness of the society of that time played the celebration in the honour of the monastery patron with the representatives of all classes of the society of that time taking part in it.

Summary. The purpose of the research is to introduce a documentary source from the middle of the 18th century into the scientific circulation, in particular. The document in question is the census of the Jewish population of the city of Stara Sil in the Przemysl land in 1764. The methodology of the research is based on the principles of historicism and the use of methods acceptable for the study of microhistory, the history of local social groups. The scientific novelty – for the first time a historical source which allows reconstructing the demographic component of the history of Jews in the territory of Przemysl land of the early modern period is introduced into scientific circulation. In the absence of statistical information for the specified period and the absence of metric records, this census remains almost the only document that forms an idea of the number and family structure of the Jewish community in a particular city. The document proposed for publication can be used for demographic research, genealogy and in related scientific topics devoted to the history of the Jewish society of the Carpathian region in the early modern period. Conclusions as a result of archival searches, a historical source was discovered and introduced into scientific circulation. This historical source is the census of the Jewish population of the Przemysl land in the mid-18th century. The information in it allows you to find out certain aspects of the life and activities of the Jewish community of Stara Sil and the Przemysl land of early modern times.
