China’s Arctic Policy: Challenges to Regional Security (1990s – 2020s)
Authors:   the Institute of History of Ukraine, the National Academy of Sciences of Ukraine, Horobets Oleksandr
Published: December 2021

The article analyzes the evolution of China's Arctic policy, which has expanded over three decades from individual polar research to observer status in the Arctic Council and the existence of a state Arctic strategy. China and Russia have established mutually beneficial cooperation in the Arctic region in such conditions, when in many areas there are fundamental contradictions between the countries. The West did not have a long-term strategy capable of responding to current security challenges, including in the Arctic. When Russia tried to regain lost positions on the world stage in 2007-2008, China became an increasingly influential player in the world. If before the Arctic had been outside the lines of rivalry for decades, the question of the Far North as an arena of military competition began to take first place. China has become a long-term threat to both the United States and Russia. In previous years, with the help of the China, Moscow had the opportunity to receive the necessary investments and technologies for large-scale Arctic projects. The more Beijing attempts to establish itself as an influential player in the Arctic, the more the threat to other Arctic countries will grow. The Russian Federation has positioned itself as a leader in the region. The country's policy was aimed at strengthening this status through regional control and expansion of the military presence. This led to a response from the United States and NATO countries. In Russia it was assessed as a threat. The question arises as to what the strategy of the United States should be, and whether it will be possible to resist the costly arms race. If not, then the competition will be concentrated in the political and economic spheres. A particular aspect is the rapid militarization of the Arctic region after 2014, primarily due to changes in Russia's military strategy, which extends to the North. This has led to the tensions between the United States and Russia. China has not yet resorted to expand its military power in the Arctic. China's policy of economic and infrastructural influence is opposed to military methods. The effectiveness of Chinese non-military methods of influence is assessed
Issues of the History of the Greek Presence on Ukrainian Territory in Modern National Historiography
Authors:   the Institute of History of Ukraine, the National Academy of Sciences of Ukraine, Piskizhova Vladyslava
Published: December 2021

The purpose of the study is a historiographical analysis of the works of modern Ukrainian historians on the issues of ethnic history of the Greeks of Ukraine, who belong to its oldest and most stable ethnic communities. In this regard, several tasks are set, one of which is to define main thematic areas of these studies and the degree of their analysis. The methodology is based on the scientific principles of historicism and objectivity. Specific scientific methods of historiographic analysis, synthesis, ideographic and other methods were used. Scientific novelty is determined primarily by the fact that this topic within the outlined chronological boundaries has not become the subject of a separate scientific study so far. Conclusions: Development of issues of ethnic history of the Greeks of Ukraine, which was initiated in the studies of scholars from Western European countries and the Russian Empire at the end of the XVIII – XIX centuries and has evolved significantly thanks to the scientific achievements of Soviet historians, received a new impetus in the early 1990s in the works of Ukrainian historians. The emergence of another wave of scientific interest in this topic is associated with the reset of the national historical science after the proclamation of independence of Ukraine, the imperatives of state ethnopolitics, the demands of the Ukrainian public, etc. These developments are based on a wide range of newly discovered sources and are characterized by modern research approaches, rethinking key issues of the problem, developing new theories (primarily on the ethnogenesis of Urums and Roumeans), etc. It is determined that a significant contribution to the study of the issue was made by the staff of the Institute of History of Ukraine of the National Academy of Sciences of Ukraine, in particular the Cabinet of Ukrainian-Greek Relations (since 2007 – Research Center for Ukrainian-Greek Relations) headed by N.O. Terentyeva. Against the background of a wide variety of issues on the ethnic history of Ukrainian Greeks, which have a fairly high level of development today, primarily in the history of the Greeks of Nizhyn and North Azov region, their national and cultural life in independent Ukraine is the least represented

Published: December 2021

Objetivo: Describir la técnica quirúrgica, las indicaciones y los resultados iniciales de la osteotomía periacetabular bernesa para tratar la displasia del desarrollo de la cadera. Materiales y Métodos: Entre mayo de 2011 y mayo de 2020, se realizaron 44 osteotomías periacetabulares bernesas en 44 pacientes (35 mujeres, edad promedio 30 años [rango 23-38]). Todos tenían diagnóstico de displasia de cadera sintomática. El ángulo centro-borde promedio fue de 17° (rango 9°-20°) y el índice acetabular promedio, de 18° (rango 15°-20°). En 22 casos, se evaluaron y repararon los hallazgos intrarticulares por artroscopia en el mismo acto quirúrgico. Se evaluaron la corrección obtenida, la consolidación de la osteotomía y los resultados funcionales al final del seguimiento. Resultados: En 22 pacientes, se detectó hipertrofia y rotura del labrum acetabular asociadas a displasia de cadera. Diez pacientes tenían quistes paralabrales. El ángulo centro-borde promedio posoperatorio fue de 32° (rango 27°-35°) y el índice acetabular, de 6° (rango 4°-9°). El tiempo quirúrgico para la osteotomía periacetabular bernesa fue de 130 min, cuando se sumó un procedimiento artroscópico, el tiempo fue de 148 minutos. Conclusiones: La osteotomía periacetabular bernesa es técnicamente demandante, pero logra resultados predecibles en pacientes con integridad del cartílago articular y deformidades corregibles. La artroscopia antes de la osteotomía permite evaluar las condiciones del cartílago, diagnosticar y tratar lesiones intrarticulares asociadas con esta enfermedad y decidir si es necesaria la corrección del déficit de cobertura.

Published: December 2021

OBJECTIVES

The individualized curriculum within residency programs allows residents to tailor their elective time toward future career goals and interests. Our objective was to identify experiences and activities that would foster resident interest and enhance preparation for a career in pediatric hospital medicine (PHM).

METHODS

Electronic surveys were distributed to pediatric hospitalists, PHM fellowship directors, and graduating PHM fellows. These stakeholders were asked to identify key experiences for residents to explore before entering fellowship or practice. Descriptive statistics and thematic analysis were performed on survey responses.

RESULTS

Forty-six percent of PHM fellows (16 of 35), 42% of pediatric hospitalists (149 of 356), and 58% of fellowship program directors (35 of 60) completed the survey. All 3 groups identified complex care as the most important clinical experience to gain in residency. Other highly valued clinical experiences included pain management, surgical comanagement, and palliative care. Lumbar puncture, electrocardiograph interpretation, and airway management were identified as essential procedural skills. Nonclinical experiences that were deemed important included quality improvement, development of teaching skills, and research methodology. All groups agreed that these recommendations should be supplemented with effective mentorship.

CONCLUSIONS

Identification of key clinical experiences, nonclinical activities, and mentorship for residents interested in PHM may assist with tailoring the individualized curriculum to personal career goals. Incorporating these suggested experiences can improve preparedness of residents entering PHM.
Façam completo silêncio

O presente artigo surgiu de uma necessidade de pensar o tema da lentidão e do questionamento na obra de Carlos Drummond de Andrade, tomando como ponto de partida estes dois elementos enquanto geradores de uma ideia de diferença. Para isso é estudada a forma como a poesia de Drummond pensa a diferença através de um constante apelo à desaceleração que cruza a sua criação literária, desaceleração da escrita, mas também da leitura, do processo criativo e de um contacto mais intenso com a realidade. Para isso são estudados e alguns poemas de Carlos Drummond de Andrade em contacto com poetas como Manuel Bandeira, Wislawa Szymborska e Jorge Luís Borges.

A representação do cidadão (português) medíocre em Dulce Maria Cardoso
Authors: Bozzo Gabriela Cristina Borborema
Published: December 2021

O cidadão (português) medíocre é aquele que abdica da própria individualidade, se aliena, se rende ao sistema socioeconômico e é submisso. Assim, o cidadão (português) medíocre figura, em uma seção da obra de Dulce Maria Cardoso, um ser sem nome, sem identidade fixa, chamado de “funcionário”, que são todos parecidos uns com os outros, para desidentificar a humanidade deles. Nosso corpus, por sua vez, é composto por Campo de sangue e Os meus sentimentos, os dois primeiros romances publicados pela escritora portuguesa contemporânea. Objetivamos, no presente artigo, delinear o perfil desses ditos “funcionários”, bem como investigar sua presença e função no corpus. Para tanto, embasar-nos-emos em O que é a não pertença e como se dá a sua construção em Os meus sentimentos, de Dulce Maria Cardoso, de Gabriela Cristina Borborema Bozzo; Manifesto comunista, de Marx e Engels, Adorno e Freud em “Civilização e alienação: diálogo com Freud e Adorno” (2006), de Danelon e O romance português contemporâneo (1950-2010), de Miguel Real.

Published: December 2021

Crocodilian-human conflicts, caused especially by urban expansion and habitat destruction, have been considered one of the main threats to the conservation of these species worldwide. In Brazil, such conflicts have been documented with crocodilian species all over the country. This study identified 400 conflict events between humans and caimans within Brazilian cities between 2016 and 2021. Caiman latirostris (57.4%) was the most common species found in large urban centers in the Northeastern and Southeastern regions. Most of the encounters (N = 250) were registered in the rainy season and the rescues were mainly carried out by the environmental military police and fire brigades. The management protocols in the presence of crocodilians in urban areas have been outlined, to be carried out by the Municipal Environmental Secretariats to minimize animal stress and the risk of accidents in urban areas. The increasingly common interaction between humans and caimans in urban environments is an important alert to envisage best conducts for the coexistence between humans and crocodilians and shows the need to invest in public policies to mitigate the effects of cities on wildlife.
A new locality for the rare Guerreran Centipede Snake, Tantilla coronadoi Hartweg, 1944 (Squamata, Colubridae), with comments on morphological variation
Authors: Palacios Aguilar Ricardo , Santa Cruz Padilla Samuel A. , Jiménez Arcos Víctor H.
Published: December 2021

We record the third known specimen of Tantilla coronadoi Hartweg, 1944 from Guerrero, Mexico. Our new record extends this species’ distribution by 90 km and to a new Mexican biogeographic province (Balsas Basin). The morphological similarity between this and the two previously known specimens supports the validity of the taxon, and otherwise points to the possible presence of an undescribed taxon on the coast of Guerrero. Additional fieldwork yielding a larger series of this and other infrequently encountered species may enable a better understanding of their distribution, natural history, ecology, and conservation.

Este artículo,  tiene como objetivo el diseño de un modelo de gestión conceptual para  representar el acoplmiento que surge en la relación de algunas normas  del Organismo Internacional de Normalización (ISO) y los modelos de Gestión del Conocimiento (GC),  esto debido a la insuficiencia que manifiesta la Norma Tecnica Colombiana (NTC) ISO 30401 donde indican como  la Gestión de la calidad, vista desde una perspectiva mecanicista, ya no es suficiente para dar una respuesta efectiva e integral a las demandas del entorno, esta NTC reconoce las habilidades blandas que se originan de la acción humana, y en ese sentido el conocimiento como  un factor vital de los fenómenos económicos contemporáneos. Igualmente resalta esta norma, la deserción y la rotación del personal en la sociedad actual, que tiene serias implicaciones en la gestión del conocimiento.  Para este estudio se tiene en cuenta una población empresarial de impacto en la ciudad de Medellín, donde se describe los Modelos de Gestión del Conocimiento (MGC) de estas, la aplicabilidad, he impacto en los procesos de producción y servicios a la medida que proponen normas de calidad a su proceso.  Se aplica una metodología propositiva y cualitativa a través de una investigación documental, que permite lograr la identificación de componentes conceptuales que son representados en el nuevo modelo, siendo un fin del modelo hacer parte cultural del diagnóstico para un plan de mejoramiento continuo en las organizaciones, particularmente aquellas empresas que aun no adoptan estas temáticas.

Published: December 2021

Background. Hermansky–Pudlak syndrome type 6 is rare hereditary disease caused by pathogenic variants in base sequence, deletions, and insertions in the HPS6 gene encoding the transmembrane protein of the same name. This disease occurs with hemorrhagic syndrome, oculocutaneous albinism, and inflammatory bowel diseases (in some cases). The clinical picture of the disease, including the gastrointestinal tract pathology, has not been studied completely due to the syndrome rarity.

Clinical case description. We would like to present the description of clinical case of the patient with Hermansky–Pudlak syndrome type 6 accompanied with bowel vascular malformation. The patient diagnosed with “oculocutaneous albinism” at the age of 4.5 has shown recurrent intestinal bleedings, blood hemoglobin concentration decrease to 45 g/l; platelet count, mean platelet volume and platelet distribution width remained within the reference values. Slight decrease of Quick’s value to 68% (normal range 70–120%) was revealed. The study of platelet morphology has revealed a decrease in the number of dense granules: < 3 in 25% platelets, < 6 — in 64%. Ultrasound investigation has revealed signs of vascular malformation in ascending colon: significant changes of diameter (widening) and shape of intestinal wall vessels. Molecular genetic analysis (NGS) has revealed the nucleotide variant c.1133T>G (p.Leu378Arg) in homozygous state in the HPS6 gene. The same variant in homozygous state was revealed in the younger proband sister who also had vascular changes in the ascending colon wall.

Conclusion. Differential diagnosis of Germanic–Pudlak syndrome type 6 should be performed with other types of this syndrome as well as with syndrome and non-syndrome forms of oculocutaneous albinism. Molecular genetic confirmation of the diagnosis is suggested via massive parallel sequencing (NGS) methods (exome sequencing included) due to the rarity of Hermansky–Pudlak syndrome.

Authors:   Perm State University, Lutmanov Sergey
Published: December 2021

The article solves the problem of optimal control of a rocket projectile by its delivery from a given initial position to a given final position, taking into account the air resistance force. The motion of the projectile is described by the vector differential equation of I.V. Meshchersky. The control quality criterion is taken in the form of "minimum force", the minimization of which ensures minimal overloads for the projectile. Three types of the norm of the control force vector are considered. For each of them, an optimal control is obtained that solves the task. The analysis of the results of the numerical experiment is carried out, confirming the general theoretical provisions.

The effect of various types of surfactants on the complexation of aluminum and iron (III) ions with eriochromecyanine R have been studied. According to the light absorption spectra of the dye and complexes with metal ions without surfactants and in the presence of catamine AB, oxyphos B, and syntanol DS-10 at various pH and the concentration of surfactants determined the optimal conditions for complexation have been determined. Oxyphos B has a negative effect on the spectrophotometric characteristics of the complexes. Syntanol DS-10 has practically no effect. The presence of catamine AB causes a bathochromic shift in the maximum of light absorption of the complex, increases the contrast of the photometric reaction and the value of the extinction coefficient. The composition of the complexes in the absence and in the presence of catamine AB has been determined by saturation and isomolar series methods. The presence of catamine AB increases the molar ratio of metal: reagent in the complex from 1: 2 to 1: 3. By Babko's method, conditional stability constants of the complexes have been determined, calibration curves have been constructed, and molar light absorption coefficients have been calculated.

Published: December 2021

Este artículo, corresponde al resultado de una investigación en la que se analizaron un conjunto de proyectos sobre el ámbito educativo, a la luz de los planteamientos de la teoría sociológica del conocimiento de Norbert Elías. Particularmente, el ejercicio de investigación se desarrolló desde dos términos que condensan su propuesta teórica: compromiso y distanciamiento. Como resultado, se esboza una caracterización de dichas investigaciones, identificando su tendencia hacia el compromiso (postura basada en las emociones y la experiencia) o hacia el distanciamiento (postura basada en la racionalidad). Finalmente, este artículo cierra con una reflexión sobre los aspectos con los que es preciso estar distanciados o comprometidos si el objetivo es construir, mediante la investigación, conocimiento cada vez más adecuado y pertinente sobre la educación.
Bases modernas/coloniales de la razón evaluadora: racismo epistémico, eurocentrismo, violencias
Authors: Giuliano Facundo
Published: December 2021

El presente artículo convida exploraciones y reflexiones provenientes de investigaciones en curso, sobre las bases modernas/coloniales de la razón evaluadora. Partiendo de la pregunta mínima por el racismo epistémico, nos adentramos en fuentes de análisis que invitan a pensar cómo al interior de la educación habita, desde la Conquista de América y el establecimiento de la modernidad/colonialidad, dicho tipo de racionalidad y su eurocentrismo como referencia inexorable en la configuración de planteamientos pedagógicos que se alinean con las necesidades cognitivas del capitalismo. En este sentido, se indaga sobre la formación de la escuela moderna/colonial que convierte a enseñantes en examinadores, evaluadores, ejecutores, y a estudiantes en subjetividades sospechosas potencialmente condenables y culpables hasta que demuestren lo contrario. Por ello, se dedica un pasaje a analizar la figura del evaluador y se continúa con un abordaje de algunas violencias implicadas en su razón (patriarcal) de ser y hacer. Desde allí, percibimos un conglomerado experiencial que intenta metaforizar el maltrato a la educación (como fuerza vital y no como cosa disciplinar) por avistar avatares pedagógicos de alteridad que habiliten un desprendimiento como re-existencia educativa. Hacia el final, se brinda una discusión con bell hooks como forma de ver diferentes persistencias del problema y la importancia de descolonizar la educación como práctica de la libertad. Por último, se explicitan las mañas “metodológicas” conjugadas (la ironía vital, la letra de lo mínimo, la sensibilidad fronteriza) en la travesía y se recapitulan aspectos medulares en torno a una educación festiva con un inaplazable trasfondo de lucha.

The data for the analysis were obtained during the summer (2021) survey of 580 small business owners, a sample of which was formed from the database of the Institute's project "Public Opinion Foundation" "Sociology of Small Business (SMBiz Project)". This database was gained in years of all-Russian population surveys conducted on random samples. The main hypotheses of the study were confirmed. They are formulated as follows: (1) Small business is not homogeneous in its attitude to the policy pursued by the state, which can be influenced by different circumstances and factors (experience in business, its success, location, etc.). (2) Participation in certain state support programs increases the level of confidence in the state and has a positive effect on the assessment of its policy. (3) The measures implemented by the Russian state during the pandemic have had different coverage and different effectiveness in the perception of their beneficiaries. In the concluding part, evidence and recommendations are formulated for the bodies implementing the policy on SMEs in Russia.

Authors: Harishchandra Shah , Basu Dev Pandey
Published: December 2021

With the objectives of determining the association between risk factors and Dengue Fever (DF), a case-control study with a random sample size of 102:102 in each was conducted at Hetauda and Kamalamai Municipalities, Nepal. The hypothesis of risk factors for DF like low level of knowledge about DF, discarded receptacles, old tires, containers, etc. nearby house, and use of stagnant AC/Coolers was used to conduct the study. Traveling to DF affected areas nearly 2 weeks before the onset of disease was significantly associated with dengue fever (OR= 6.10, 95% cl: 1.31-28.34, p<0.021). Waste disposal of old containers, receptacles, tires during the rainy season were significantly associated with the incidence of DF (AOR= 6.308, 96% cl: 2-751-14.462, p<0.000). The frequency of DF was associated with the middle social class level (p<0.05, d. f. 2). Uncovered water tanks of the household were significantly associated with DF (AOR= 3.78, 95% cl: 1.51-9.45, p<0.0043). As the number of families increases in the household, the number of cases increases with a positive correlation (r = +0.62). Crowded households with more than 2 occupants in one room were at risk of dengue infection. The study concluded that DF was associated with the risk factors of traveling to endemic areas, discarded waste containers, receptacles, tires, and uncovered water tanks, middle social class, and crowded households. Public health managers should prioritize these risk factors while planning for DF control and prevention.

Investigating Preservice Science Teachers’ Cognitive Structures on Environmental Issues
Authors: KIRYAK Zeynep , CANDAŞ Bahar , ÖZMEN Haluk
Published: December 2021

Environmental knowledge and awareness of individuals affect their attitudes and behavior toward the environment. In this regard, it is essential to specify how environmental issues are interpreted in individuals’ cognitive structures. This study aims to investigate preservice science teachers’ cognitive structures on environmental issues. The study was conducted with 78 third-year preservice science teachers. The data were collected through a word association test that contains eight stimulus words about environmental problems and protecting the environment. Global warming, greenhouse effect, radiation, and acid rain were chosen for environmental problems; recycling, waste disposal, sustainability, and solar energy were selected for protecting the environment. Besides, preservice science teachers were asked to write a sentence for each stimulus word. Two concept networks were created based on the cut-off point method for the word association test, and content analysis was used for sentences. Besides, by comparing the data obtained from the concept networks and sentence analysis, an attempt was made to obtain more in-depth information. It is concluded that preservice science teachers focused on daily life rather than scientific facts about environmental issues. In this respect, new courses such as Green Chemistry may effectively eliminate alternative conceptions and raise awareness on environmental issues.

The educational digital games with the children in the Experiment I group were performed with in-class educational games with the children in the Experiment II group. The research covered a 10-week period. In order to test the hypotheses of the research, t test for the related samples, Wilcoxon Signed Sequence test, single factor ANOVA analysis for unrelated samples, Kruskal Wallis H-Test and Man Whitney U-Test were performed. According to the analysis results of the scientific process skill test scores of the groups after the application, it was found that there was no significant difference between experiment I and experiment II.. It was  determined that there was a significant difference between the experiment I and experiment II groups and the control group, and this difference was in favor of the experimental groups.
Augmented Reality Application-Based Teaching Material's Effect on Viscera Learning Through Algorithmic Thinking
Authors: Güntepe Ebru Turan , Usta Necla Dönmez
Published: December 2021

The study aimed to examine AR-based teaching material's effect on viscera learning through algorithmic thinking by the primary school teacher candidates who are sophomores in the classroom teaching department in the spring term of the 2018-2019 academic year at a state university in the Eastern Black Sea and selected by convenience method. Viscera Information Form (VIF) and Application Process and AR Survey Form (APSF) were used as data collection tools in the study. VIF included subjects viscera in a human model and placed them in the skeletal structure. The other form, APSF, is about the application process and the material prepared with augmented reality. While the data obtained from VIF were analyzed under the researcher-defined categories regarding the participants' showing each viscera in a human torso model and placing them in the skeletal structure, the data obtained from APSF was processed with content analysis. The study results revealed that AR-based teaching material makes a positive contribution to the learning of viscera through algorithmic thinking. In addition, this is determined as AR-based teaching material contributes to understanding the related basic concepts through algorithmic thinking.

Authors: Keçeci Gonca , Yıldırım Pelin , Kırbağ Zengin Fikriye
Published: December 2021

Mobile augmented reality (MAR) draws attention in terms of providing a flexible learning process and environment. It is thought that learning environments can be more effective using MAR technology. The research aimed to determine the secondary school students' views on the use of MAR technology in science teaching. The research was conducted with 143 students studying in the sixth grade at two different secondary schools in Turkey. In the research, convergent parallel patterns from mixed-method patterns were used. For eight weeks, the research was carried out to cover the systems unit in our body, situated in the 6th-grade science course curriculum. During the process, the Anatomy 4D application was used in the experimental group during the procedure, and the science course curriculum was used in the control group.  In this paper, a part of the mixed research, the qualitative data collected from the experimental group's semi-structured interview form and diaries were analyzed. Descriptive analysis was used to analyze the data. As a result of the research, although the students do not have a clear idea about AR and MAR technologies at the beginning of the application, it is observed that their thoughts change over time, and MAR applications are effective on the success of the course.
