ADAPTATION OF EARLY NEONATAL CHILDREN BORN FROM MOTHERS WHO REHIVED COVID-19 DURING PREGNANCY (DESCRIPTION OF TWO CASES)
Authors: Kiselova M. , Komar A. , Malanchak O. , Potsyurko O.
Published: November 2021

The frequency of detection of infected children with SARS-CoV-2, which is 10% of the total number of infected, including newborns, suggests the need for careful diagnosis of pathological conditions that may occur in children, particularly in the neonatal period. If at the beginning of the detection of COVID-19 it was claimed that the coronavirus SARS-CoV-2 does not affect children, then analyzing the new data we see that 2% of patients with diagnosed clinical cases of COVID-19 are children, including newborns.

The article describes observations of several clinical cases of early neonatal adaptation of children born to women who had mild to severe COVID-19 during the first and third trimesters of pregnancy, respectively, because these children at birth had vesicular rash, symptom, which is considered rare for this category of newborns. In 2020, 2,300 newborns were born in the neonatal department of the 3rd City Clinical Hospital of Lviv, with every 5th woman in labor (20%) relapsed to COVID-19 during pregnancy.Analyzing the course of early neonatal adaptation, we found that the adaptation period of such children may not differ from the adaptation of newborns in the number and manifestations of transient conditions characteristic of the first days of life, whose mothers did not suffer from COVID-19 during pregnancy. However, coronavirus infection in women in both the first and third trimesters of pregnancy may be associated with signs of congenital vesiculosis in children, accompanied by inflammatory changes in the blood and blood clotting in the period of early neonatal adaptation in the newborn. Children had no other signs of pathological symptoms (fever, lethargy, drowsiness, hypotension, rhinorrhea, pharyngitis, cough, respiratory disorders (tachypnea, wheezing), vomiting, diarrhea and feeding disorders)), characteristic of infectious diseases specific to newborns, which can be masked by transient states. Manifestations of transient conditions in the observed children were: milia, simple erythema, desquamative peeling of the epidermis, toxic erythema, physiological jaundice.Treatment of the affected areas of the skin with rash elements with 0.05% aqueous solution of chlorhexidine, a three-day course of ampicillin, administered to the child from the first hours of life at a dose of 100 mg / kg / day intravenously contributed to the disappearance of vesiculosis. The maintenance therapy was a multiprobiotic in the form of drops. In the presented cases, no obstacles to breastfeeding and cohabitation of mother and child were observed. In the departments of newborn maternity hospitals, it is necessary to find opportunities, for diagnostic purposes, to conduct microbiological studies of pustules and biomaterial from the mucous membranes of the genital tract to further compare the results and establish etiological factors of vesiculosis, determine biochemical blood tests - CRP, ALT, AST, LD serum, coagulation parameters.

Cultura política del diario La Nueva Provincia en la gestación del peronismo
Authors: Violi Cattaneo César Alejandro
Published: November 2021

El presente trabajo pretende reconstruir la cultura política de La Nueva Provincia en el período que va desde el golpe de Estado del 4 de Junio de 1943 al triunfo del peronismo en febrero de 1946. En cuanto al objetivo específico, la intención es observar qué postura adoptó el diario ante el período y acontecimientos presentados. Además, se hará hincapié en la forma en que fue visto el crecimiento de la figura de Juan Domingo Perón. Abordaremos el estudio del perТodo mencionado (1943-1946), empleando a los efectos de su anЗlisis el concepto de Cultura Política, entendiendo al mismo como un conjunto de representaciones portadoras de actitudes, creencias, ideales, valores y conocimientos que constituyen la identidad de las grandes familias políticas. Consideramos que, al mismo tiempo que estructura las conductas políticas de los individuos, es un fenómeno colectivo que funda la identidad del grupo. La presente propuesta pretende contribuir al análisis de la cultura política de la Nueva Provincia durante un período prácticamente no estudiado intentando tomarlo como una fase con entidad propia y no como mero tránsito hacia el gobierno de Juan Domingo Perón.

Authors: Ávila Landa Homero
Published: November 2021

Este artículo destaca repertorios culturales puestos en juego en una representación rockera en la región Altos de Chiapas, escenario del bats′i rock o rock verdadero. A partir de un concierto del grupo zinacanteco Lumaltok, en San Cristóbal de las Casas, ante público local, reflexionamos sobre el “rock indígena”, que combina simbología de la cultura maya tzotzil con elementos del acervo gestual rockero. Sucintamente, se ofrecen datos relativos al fenómeno en la región; se delinea al actor estatal relacionado con ese rock mediante el programa De Tradición y Nuevas Rolas; y desde los estudios del performance se hace interpretación sobre la singularidad de ese rock. Se concluye que en esta representación el músico vehicula la cultura e identidad étnica de pertenencia al tiempo, que acrisola en su obra creativa-expresiva, la música de rock, simbología proveniente de la cultura mexicana y global, recreaciones que le permiten experimentar formas de libertad.
La lírica yucateca: hija de Erato y Calíope, heredera de Itzamnaaj
Authors: Ramírez Uribe Claudio
Published: November 2021

Esta colaboración tiene el propósito de presentar una panorámica histórica del desarrollo de la tradición poética en Yucatán. Primero se aborda el desarrollo lírico peninsular heredado del Siglo de Oro español y cómo este es compartido por otras tradiciones populares caribeñas, representadas en Yucatán por las vaquerías y las bombas yucatecas. Subsecuentemente se revisa el cambio en el gusto yucateco del siglo XIX hacia las corrientes romántica y modernista, y cómo estas serán las bases de lo que en el siglo XX se llamará trova yucateca y de la tradición del bolero.
“Imágenes dantescas”. Fotoperiodismo sobre feminicidios en Veracruz
Authors: Casados González Estela
Published: November 2021

Los medios de comunicación construyen opinión pública en torno a la violencia hacia las mujeres. A su vez, son reflejo de la permisividad, tolerancia y naturalización con la que la sociedad aborda temas como el feminicidio. El objetivo de este documento es centrarnos en el manejo que se hace desde el fotoperiodismo sobre los asesinatos de mujeres. El uso de la imagen y la narrativa gráfica de los hechos nos ofrece una veta de interés a partir de la cual se analizan los mecanismos que reivindican la identidad de género tradicional y la sujeción patriarcal que se cierne sobre ella.

Objectives: To try another non-invasive method to evaluate the relationship between Magnetic Resonance (MR) elastic value and pathological grade of Hepatocellular Carcinoma (HCC) using Magnetic Resonance Elastography (MRE). Methods: Forty-seven HCC patients underwent MR Imaging (MRI), elastography in the upper abdomen. The elastic value of the lesion area was measured, and that of the normal liver tissue was measured adjacent to the lesion area at the same level. The Mann-Whitney U test was used to compare the difference in elasticity between the lesion area and normal area, and the difference between the low and middle-high differentiation groups. The Receiver Operating Characteristic Curve (ROC) of the lesion area and normal area in the complete case group and different differentiation groups were used to determine the diagnostic cut-off value to distinguish the lesion area from the normal area in each group. Results: (1) There was a significant difference in elasticity between the normal area and HCC area (p<0.001). The diagnostic cut-off value was 4842 Pa. (2) There was a significant difference in elasticity between the low-and middle-high differentiation groups (p<0.001). The diagnostic cut-off value was 10456 Pa. (3) There was a statistically significant correlation between the elastic value on MRE and degree of pathological differentiation of HCC in the two groups (p<0.001). Conclusion: The elastic value of HCC measured using MRE can be used to evaluate the degree of pathological differentiation of HCC. MRE may be a non-invasive and reliable method for evaluating the pathological grade of HCC.

Eve, Magdalina, Samaritian... (To the Typology of Female Images in the Novel of L. M. Leonov “Thief”)
Authors: Zadorina Alena O.
Published: November 2021

Purpose. The article presents the results of the analysis of key female images in the novel by L. M. Leonov “Thief”: Masha Dolomanova, Tatiana Vekshina, Zinaida Balueva, Ksenia Babkina – whose fates are united by a typological commonality. The relevance of the study is due to the rethinking of the role of women in the modern world and art, and the formation of heroines, unhappy men in the world of men, in the literature of the 20th century developed, including under the influence of post-revolutionary, post-war reality, under the influence of urbanization.

Methodology. The study based on the works devoted to the poetics of motif, image. To achieve the goal, the following tasks were set: determination of artistically significant motives; comparison of plot lines with precedent texts (mostly biblical); explanation of details that clarify the essence of female images. Using the method of motif analysis, identified the main motives involved in creating the storylines of each heroine, and their variants.

Results. The motif of violence is highlighted, which is presented in the following allomotives: sexual violence (including deprivation of innocence) – for all heroines, except for Zinaida Balueva; physical violence (beating) – images of Masha Dolomanova, Zinaida Balueva – and suicide (Ksenia Babkina); psychological abuse (like suppression of will, lack of care) – all heroines. Within the framework of the method of structural-typological analysis, female characters were correlated with the poles of the binary opposition between the evil wife and the good wife, ascending to the Holy Scriptures. It was found that, in addition to the motive of violence, which is present in the storyline of each heroine, but conditioned not by the will of the person, but by chance, Leonov’s female characters are united by the motive of temptation, temptation, which allows one to assess their individual position and explain the tragic outcome of life.

Conclusion. The female images in the novel “Thief” are comparable with such biblical personalities as Eve, Mary Magdalene, an unnamed Samaritan woman, Tatiana the Martyr. Their fates are determined by the actions or desires of other heroes, which, given the fact that they have not found their own God, ultimately leads to despair and irrevocable death.

The author analyzes the monograph “Utopian discourse in Russian culture of the late 19th – 21st century. Literature. Painting. Cinema”. The review determines the position of this book in modern science of projective models of the future. A key aspect is the continuity of previous studies on the category of utopia, and above all, B. F. Egorov, whose memory the book is dedicated to. The transition of modern art beyond the utopian genre is noticed. This confirms the appropriateness of the discursive technique. The author emphasizes the relevance of the traditional conversation about environmental problems and expresses bewilderment at the disregard by Western philologists of Russian fiction and scientific literature. As an unquestionable advantage of the monograph, its modern anthropological approach to the psychological details of private narrative utopias is noted.
The “Bird Catcher” From Remizov’s “Nest”: To the Paris Biography of the Poet Dmitry Kobiakov
Authors: Obatnina Elena R.
Published: November 2021

The article is dedicated to unknown plots from the biography of Dmitry Kobyakov – one of the poets of “lost generation” who shared the fate of post-war Soviet repatriates. On the basis of unpublished letters of Kobyakov from the American archive of A. M. Remisov the author reveals the motives of the rapprochement of a famous writer and an aspiring poet. At the external level it was connected with the publication of Kobyakov’s verse books, but on a latent level had according with innovative trends in artistic poetic and prosaic discourse of the second half of the 1920s. The article presents the first part of the study devoted to the literary life of Russian Paris, in the center of which with the support of Remizov appeared unknown Dm. Kobyakov; it contains substantial additions to the literary portrait of young Remizov’s correspondent, as well as to the bibliography of Russian abroad. The description of the history of these creative contacts is the object of new documentary materials that also fill the gaps in Remizov’s biography concerning the topic of literary mentorship of the writer and ‘nest’ of young writers had formed around him in the 1920s – early 1930s.
The Language of “Overthrown Religion”: Tvardovsky about God
Authors: Pavlova Larisa V. , Romanova Irina V. , Kazartsev Evgeny V.
Published: November 2021

Purpose. In the literature about A. T. Tvardovsky, the theme of the writer's religiosity was rarely touched upon. The memoirs of contemporaries retained contradictory facts, by which it is difficult to judge Tvardovsky’s true convictions. This article presents the results of the study of the language of the writer. His poetry served as the material, and “Workbooks” were also involved.

Results. Analysis of the poetic language showed that the life of the church, its language were familiar to a native of the Smolensk hinterland, as to every person of his time. Numerous References to various church realities are indicative – objects, buildings, people, sacraments, holidays. The subject of the research is the lexeme “God” and the peculiarities of its functioning in the poetic language of Tvardovsky, as well as, for comparison, in his documentary prose.

For the early Tvardovsky, the rejection of the “old world” and its beliefs for the sake of Marxist-Leninist ideology is relevant. One of the vivid evidence of this refusal is the reduction of the constants of the religious thinking of the Russian person to sayings, idioms, and mentioning God in vain. The most categorical atheistic statements are put into the mouths of the heroes of the poems, for example, Nikita Morgunok and Terkin. The word God in idiomatic expressions is usually desemantized. Leaders, political and cultural idols are most often compared with God.

Later, Tvardovsky significantly softens his atheistic positions, showing signs of spontaneous faith. He writes the penitential poem “By the Right of Memory”, becomes more careful and selective in expressions. Prose speech is enriched by a more conscious mention of God, mainly in contexts of supreme judgment, repentance and miraculous help. Tvardovsky opposes aggressive ideological policies that rudely try to replace one religion with another. In this process, he sees a metaphysical transition to the side of Evil.

Conclusion. Tvardovsky experienced a spiritual evolution from militant autheism to a spontaneous faith, in which he was most worried about the problems of Higher Judgment and repentance. The highest value for him continued to be a person.

Исследовано взаимодействие коллагена пресноводных рыб с водой для повышения его водопоглощающей способности. Объектом исследования был вторичный продукт переработки рыбного сырья – шкуры прудовых рыб, преимущественно толстолобика. Для исследования были использованы методы термогравиметрии и дифференциальной сканирующей калориметрии. Измерения проведены на приборе синхронного термического анализа модели STA 449 F3 Jupiter. Установлено, что основная доля влаги связывается адсорбционным или осмотическим путем, а на долю капиллярной влаги приходится всего 7% массы воды, связанной образцами. Большая величина энергии связи адсорбции – 4 Дж/моль свидетельствует о способности функциональных групп коллагена к созданию гидратной оболочки, содержащей значительное количество воды. Для увеличения влагопоглощающей способности необходимо разрыхление коллагеновых волокон, что увеличивается свободный доступ влаги к фибриллам белка, увеличивающим впитывание влаги. Для эффективного разрыхления предложено выдерживать шкуры толстолобика в растворе органических кислот концентрацией 0,5%. Это позволяет добиться высокой влагоемкости, которая достигает 35–40 объемов влаги на 1 единицу массы исследуемого материала, что делает перспективным использование коллагена в качестве материала для впитывающих влагу слоев средств личной гигиены, одежды, обуви.

The interaction of freshwater fish collagen with water to increase its water absorption capacity was studied. The secondary product of processing of fish raw materials – skins of pond fish, mainly silver carp, was the object of study. Methods of thermogravimetry and differential scanning calorimetry were used for the study. Measurements were carried out on the device of synchronous thermal analysis of model STA 449 F3 Jupiter. It was found that the bulk of the moisture is bound by adsorption or osmotic way, and 7% of mass of the water connected by samples fall to the share of capillary moisture. A large amount of adsorption binding energy – 4 J/mol indicates the ability of collagen functional groups to create a hydrated shell containing a significant amount of water. Loosening of collagen fibers is necessary to increase the moisture absorption capacity, which will increase the free access of moisture to the protein fibrils, increasing the absorption of moisture. It is proposed to withstand the skins of silver carp in a solution of organic acids with a concentration of 0,5% for effective loosening. This makes it possible to achieve high moisture capacity, which reaches 35–40 volumes of moisture per 1 unit mass of the test material, which makes it promising to use collagen as a material for moisture-absorbing layers of personal hygiene products, clothing, and shoes.

Описана динамика выделения растительного масла из пористого материала в процессе его ламинарного слоистого течения, вызванного движущимися с заданной постоянной скоростью стенками канала шнека и неподвижной крышкой. Получена адекватная модель кинетики отжима в зеерной камере пресса, позволяющая прогнозировать работу витков маслоотжимных агрегатов по пропускной способности каналов, образованных витками шнека и выпускного устройства. Установлено, что динамика отжима масла из масличного материала определяется уменьшением потока материала по длине винтовой линии. Практически линейный характер изменения давления в зеерной камере показывает отсутствие гидравлических потерь в процессе отжима.

The dynamics of the release of vegetable oil from a porous material during its laminar layered flow caused by moving at a given constant speed the walls of the screw channel and the fixed cover is described. An adequate model of the spin kinetics in the zeer chamber of the press, which allows to predict the work of the turns of the oil extraction units by the capacity of the channels formed by the turns of the screw and the exhaust device, is made. It is established that the dynamics of oil extraction from the oil material is determined by a decrease in the flow of the material along the length of the helix. The almost linear nature of the pressure change in the zeer chamber shows the absence of hydraulic losses during the extraction.

Разработан экспресс-метод определения йодного числа в жирах и маслах, исключающий применение агрессивных и токсичных реагентов и значительно сокращающий длительность измерения. Разработанный метод позволяет определить показатель степени непредельности жиров и масел, жиросодержащих пищевых продуктов. Методика предусматривает предварительную обработку масел в МХА. Затем навеску исследуемого вещества от 0,03 до 0,05 г, взятую с точностью до ± 0,0002 г, помещают в сухую коническую колбу с притертой пробкой. В колбу вносят 10 см3спирто-эфирной смеси (1 : 1), тщательно перемешивают. Затем к навеске добавляют 30 см3 спиртового раствора йода концентрацией 0,1 моль/дм3, перемешивают. Приливают 100 см3 дистиллированной воды. Колбу закрывают пробкой, встряхивают и выдерживают в темноте 20 мин. Избыточный йод оттитровывают раствором тиосульфата натрия концентрацией 0,1 моль/дм3. Перед окончанием титрования, когда раствор приобретет соломенно-желтый цвет, добавляют 1 см31%-го раствора крахмала и титруют до исчезновения синей окраски. Относительная погрешность определения йодного числа по разработанной методике невелика – от 0,141 до 0,149% при надежности 0,95. Разработанный метод рекомендован для оперативного определения йодных чисел масел и жиров в производственных и лабораторных условиях. Оперативность метода позволяет быстро вносить изменения в технологические процессы и обеспечивать стабильность производства и качества продукции.

The express method of determination of iodine number in fats and oils, excluding the use of aggressive and toxic reagents and significantly reducing the duration of measurement, has been developed. The developed method allows define degree of unsaturated of the fats and oils containing fat of products. The technique involves the pretreatment of oils in a techno-chemical activator. Then the sample of the test substance from 0,03 to 0,05 g, taken with an accuracy of ± 0,0002 g, is placed in a dry conical flask with a ground glass stopper. In the flask make 10 cm3alcohol-ether mixture (1 : 1), mix sample thoroughly. Then add 30 cm3of an alcoholic solution of iodine with a concentration of 0,1 mol/dm3to the sample, mix. Then, pour 100 cm3of the distilled water. The flask is closed with a stopper, shaken and kept in the dark for 20 min. Excess iodine is titrated with a solution of sodium thiosulfate concentration of 0,1 mol/dm3. Before the end of titration, when the solution becomes straw yellow, add 1 cm3 of 1% starch solution and titrate until the blue color disappears. The relative error in the determination of the iodine number by the developed method is small – from 0,141 to 0,149% with a reliability of 0,95; that allows us to recommend the developed method for the rapid determination of iodine numbers of oils and fats in production and laboratory conditions. The efficiency of the method allows you to quickly make changes in technological processes and ensure the stability of production and product quality.

Published: November 2021

Conjugates comprising a semiconducting dye (Thiophene-diketopyrrolopyrrole, TDPP-dye) attached to a self-assembling peptide (HEFISTAH) assemble into long nanofibers. Well-ordered Langmuir-Blodgett films of these materials can be prepared. Networks of these nanofibres can be deposited to bridge electrodes. Although similar systems have been proposed as organic semiconductors, in this case, no electronic conductivity was observed. Instead, the fibres behaved as ionic (probably proton) conductors as a consequence of adsorbed water. A strong dependence of electrical conductivity on relative humidity and fibre network density was demonstrated. The system of nanofibers bridging gold electrodes behaved as an electrolytic cell, with oxygen reduction as a limiting electrode reaction.

Background. The problem of diagnostics and treatment of malignant neoplasms of the lungs is urgent. Verification of a malignant process in the case of peripheral localization of a neoplasm in the lung using ultrasound bronchoscopy ranges from 30 to 85%. To improve the efficiency of ultrasound bronchoscopy, a modified biopsy technique for ultrasound bronchoscopy was developed and introduced into clinical practice at the Chelyabinsk Regional Clinical Center of Oncology and Nuclear Medicine. The essence of the modified technique is that it becomes possible for ultrasound visual control over the passage and deployment of biopsy forceps in real time. The technique was patented, patent for invention RU №2719666 C1 was issued.
Aim. To clarify the information content of ultrasound bronchoscopy using a modified technique.
Materials and methods. On the basis of the endoscopic Department of Chelyabinsk Regional Clinical Center of Oncology and Nuclear Medicine in 2019 and 2020, ultrasound bronchoscopy using this technique was performed on 40 patients with suspected peripheral malignant neoplasm of the lungs. The diagnosis of malignant neoplasm was verified in 67.5% of cases. Using the standard biopsy technique, the probability of verification of lung malignant neoplasms in 2019 and 2020 was 57.7%. Thus, the modified biopsy technique made it possible to increase the verification probability by 9.8%. The modified technique is relatively safe, complications during the procedure were detected in 2 patients (in 3.8% of cases) and were successfully treated conservatively. During and after the procedure, the patients were monitored and monitored. The ultrasound bronchoscopy according to the modified technique was satisfactorily tolerated by the patients.
Results. The period of examination of patients when using this technique does not increase. The technique replaces more invasive diagnostic procedures.
Conclusion. The use of the modified technique will improve the information content of ultrasound bronchoscopy, shorten the examination time for patients and accelerate the appointment of special treatment methods.

When evaluating the effect of therapy for malignant neoplasms with inhibitors of CTLA-4, PD-1 and PD-L1, the phenomenon of pseudoprogression may occur. Pseudoprogression is an increase in the volume of tumor tissue due to immunocompetent cells (lymphocytes, macrophages) mobilized into the tumor focus under the action of immunotherapy. As the antitumor effect of lymphocytes and macrophages is realized, the tumor decreases or disappears over time. Pseudoprogression occurs with varying frequency in various types of cancer. It may also matter which immune checkpoint inhibitors is used to treat a solid tumor or lymphoproliferative disease. Currently, several immune-related response-evaluation criteria have been developed, which can help diagnose the phenomenon of pseudoprogression. But, unfortunately, none of these criteria clearly distinguish pseudoprogression from true tumor progression. In the case of an erroneous judgment about the effect of treatment, immunotherapy ends, and the patient may not get a chance for long-term remission. Using two clinical examples (immunotherapy for metastatic kidney cancer and recurrent Hodgkin lymphoma), the authors discuss the pitfalls of evaluating the effectiveness of treatment with checkpoint inhibitors.

Background. Radial forearm free flap is one of the most frequently used in the head and neck reconstruction. A significant disadvantage is the appearance of the donor site. We have developed and introduced into clinical practice a V-shaped fabrication skin of the flap, which allows direct closure of the donor site and reduces morbidity.
Aim. To assess the possibility of direct closure of the donor site and to reduce the morbidity of the donor site when performing the V-shaped fabrication of the skin area of the flap.
Materials and methods. During the period from 2014 to 2020, the radial free flap was used in 43 cases. In 15 (35%) cases, a V-shaped fabrication of the skin area was used during flap harvest, which made it possible to carry out a direct closure of the donor site. The length of the skin area stretched from the top of the wrist, not reaching 34 cm to the elbow bend and varied from 715 cm, on average 12 cm. The width of the flap was determined by the elasticity of the forearm skin, was maximum in the middle third and varied from 2 up to 4 cm, averaging 3.3 cm. If necessary, the upper and lower edges of the skin area can be sutured together, as well as the entire medial edge of the flap. This technique increases the flap width by almost 2 times. This arrangement was applied in 8 cases.
Results. When comparing the results of using the two techniques, the following data were obtained: "V-shaped" fabrication of the skin was used mainly in women (11/15 73%) for reconstruction limited defects in the retromolar region (5/15), soft (4/15) or hard palate (6/15). Most of the patients had localized T1-T2 (10/15) stage. None of the patients had any problems with the healing of the donor area. An excellent aesthetic result was obtained in all patients. In the group of standard harvest, the predominance of males was noted (17/28). Defects had a varied localization, most patients was with relapses after chemo-radiation treatment (10/28) or primary locally advanced T3-T4 stage process (6/28) 16, with a localized T1-T2 stage (11/28) 11, in one case, delayed reconstruction was performed. In all cases, the plastic of the donor site was performed with a split skin autograft. Partial necrosis of the donor site flap was observed in 9 patients (32%), in 4 cases with exposure of the flexor muscle tendon.
Conclusion. As a result of the comparative analysis of the two methods, we concluded that the use of V-shaped fabrication of the skin area of the radial forearm flap allows to obtain better aesthetic results of the donor site, however, the use of this technique leads to a significant reduction in the length of the vascular pedicle and a decrease in the width of the flap.
The Inclusion of Differentiation in Literacy Lessons in the First and Second Grades of Slovenian Primary School

In the modern educational process, teachers adapt lessons to the student’s individual abilities, prior knowledge, interests and social skills. The present study, whose aim is to examine the inclusion of differentiation in literacy lessons in the first and second grades of Slovenian primary schools, was carried out on a smaller scale (N = 79). It aims to determine the views of first- and second-grade primary school teachers on differentiation, and to find out how differentiation takes place in literacy lessons and which factors affect student performance in class. The results show that the inclusion of differentiation in literacy lessons is present in the entire initial literacy teaching process, and that Slovenian teachers undergo regular training and professional development courses in this area, thus contributing to the educational success of students and affecting their personal growth and development. Teachers estimate that the intertwining of individual abilities, family environment, engagement in co-curricular activities and well-developed social skills represents a key factor in student success. It was expected that internal differentiation would be more effective than external differentiation. Surprisingly, however, teachers report that heterogeneous groups do not enhance educational efficiency.

Objetivo. Avaliar o uso combinado de marcadores sorológicos e análise espacial para ampliar a sensibilidade da vigilância epidemiológica da hanseníase.

Método. Este estudo transversal foi realizado com vizinhos de casos de hanseníase e familiares e vizinhos de escolares com sorologia positiva anti-glicolipídeo fenólico I (PGL-I) em Diamantina, Minas Gerais, Brasil. Definiram-se como vizinhos as pessoas que residiam em um raio de até 100 metros de escolares e de casos de hanseníase. Para a coleta de dados, foram realizados entrevista semiestruturada, exame dermatoneurológico e teste sorológico rápido ML Flow. Todos os endereços foram georreferenciados. Foram realizadas regressão multivariada e análise espacial, tendo a sororreatividade anti-PGL-I como variável dependente.

Resultados. Foram estudadas 1 491 pessoas: 1 009 (67,7%) familiares e vizinhos dos escolares com sorologia positiva e 482 (32,3%) vizinhos dos casos de hanseníase. Do total, 421 (28,2%) apresentaram soropositividade anti-PGL-I. A chance de soropositividade foi maior entre familiares e vizinhos dos escolares soropositivos (P < 0,001), entre pessoas com renda familiar de 1 salário-mínimo (P < 0,001), entre os mais jovens (P < 0,001) e entre os que residiam em domicílios com um a cinco cômodos (P = 0,007). A taxa de soropositividade foi maior em área geográfica correspondente aos escolares soropositivos (P < 0,001), ou seja, houve divergência entre o foco de maior concentração de casos e o de maior soropositividade.

Conclusões. O uso combinado de marcadores sorológicos e análise espacial possibilitou identificar fragilidades operacionais dos serviços e uma possível endemia oculta de hanseníase nos setores censitários urbanos do município. Atividades de rastreamento de contatos sociais e vizinhos, busca ativa, campanhas educativas, inquéritos escolares e análise do território facilitam o diagnóstico precoce da hanseníase.

Глобалізація та інтернаціоналізація економічних відносин вимагає як формування нових, так і посилення діючих інструментів забезпечення конкурентних переваг власної економіки. Серед базових внутрішніх інструментів впливу на соціально-економічні, екологічні проблеми країни та країн-партнерів є податки й інші обов’язкові податкові платежі. Польща та Україна відновили власну незалежність одночасно на початку 90-х років XX століття і урядами країн приділялася значна увага використанню податків у реформуванні власних економічних моделей. Податки в Польщі стали елементом політики «шокової терапії», в Україні активно використовувалися урядами при послідовному реформуванні національної економіки до ринкових умов господарювання. Податки стали базовим інструментом бюджетно-податкової політики України та Польщі, однак ефективність використання виявилася різною з огляду на макроекономічні показники розвитку обох держав, соціального розвитку.
«Ніч музеїв» як успішний приклад музейної комунікації
Authors: Кругляк Марина Едуардівна
Published: November 2021

У статті розглянуто всесвітньо відому акцію «Ніч музеїв» як один з успішних прикладів музейної комунікації. Цей захід, як правило, проводиться в Міжнародний день музеїв і є одним зі шляхів створення позитивного образу музею, його популяризації та реклами. Автор подає історію виникнення цієї акції, розповідає про особливості її проведення в декількох країнах світу, зокрема акцентує увагу на досвіді сусіда України – Польщі. У тексті продемонстровано ступінь залучення музеїв України до «Ночі музеїв», показано найцікавіші атракції, що пропонувалися відвідувачам у 2017–2021 роках. Доведено, що акція «Ніч музеїв» з кожним роком набуває все більшої популярності у світі та в Україні, що до її проведення все активніше долучаються не стільки музеї, скільки установи сфери культури та освіти, зокрема, мистецькі галереї, Академії наук, університети, бібліотеки, засоби масової інформації. Наголошено на тому, що найчастіше у «Ніч музеїв» пропонується вільний вхід до установ або ж встановлюється помірна ціна за квиток. Серед найпопулярніших дійств – презентації книжок та колекцій одягу, майстер-класи та квести, театралізовані вистави, концерти, перегляди кінострічок. Звернено увагу на труднощі в проведенні «Ночі музеїв» в Україні і світі. Окрім обмежень у музеях, пов’язаних із COVID-19, в Україні до світової пандемії додаються економічні труднощі: недостатнє фінансування з боку держави, низька залученість спонсорів (особливо в провінції), пасивність пересічних громадян, нерозвиненість інфраструктури, зокрема транспортної, недостатнє використання можливостей реклами.

Exclusive breastfeeding for infants up to the age of 6 months reaches 42% while the WHO target wes at least 50%. To increase the coverage of breastfeeding, new mothers who have passed leave and have to return to work can carry out the management of Dairy Mother's Milk (ASIP) (Riskesdas, 2013). According to Kristiyansari (2009) working mothers can still breastfeed, before going to work breastfeed their babies first, then at work mothers pump breast milk and store the milk then when they get home the milk is given to the baby or stored in the refrigerator. After giving the counseling, conducting questions and answers and discussions, many asked about how to pump breast milk and how to store breast milk, especially for working mothers. Furthermore, the evaluation wes given questions to the mother and can answer even though it is not perfect in providing answers, here it appears that there is an understanding that has been received by the mother after counseling. By being given this counseling, it is hoped that from now on, mothers will learn and not be ashamed to add information to health workers about how to express and the correct technique for storing breast milk for working mothers. So that by the time the mother is working, the mother is ready and able to pump breast milk and the mother can store breast milk properly

Pre-Service Teachers in the Outdoors: A Phenomenological Exploration
Authors: Melton Josie
Published: November 2021

While a child’s sense of wonder is thought to come naturally, less is known about how adults foster or connect with their sense of wonder.  For the purposes of this exploration, wonder is the openness that comes when one dwells with the present moment, allowing questions to arise, rather than using wonder as a tool to answer a question (Gadamer, 2004; van Manen, 2014).  Spending time in the outdoors is a common way to engage wonder, but there may be differences in the ways adults experience their surroundings compared to children.  If teachers or parents aim to foster a child’s sense of wonder then it is important to understand how adults experience and connect to the outdoors so they can model and promote the connection for children.  This paper explores the experiences of adults in the outdoors in order to better understand the barriers and paths that may lead to wonder.  Five anecdotes from outdoor experiences are phenomenologically analyzed to better understand the lived experience of adults in the outdoors.  Themes from the anecdotes are discussed, as well as the implications for teacher education programs.
