Published: May 2021

Introduction: HIE is often clinically suspected in the setting of a known perinatal stress event arising from a complicated
or difcult delivery. The most sensitive and specic imaging technique for examining infants with suspected hypoxicischemic brain injury is MR imaging. It also gives information about the timing and specic patterns of injury and also suggest diagnoses other
than HIE such as metabolic disorders and developmental disorders of the brain. MRI is also a useful tool in the determination of prognosis and
also follow-up of HIE.
Aim: This study was undertaken to evaluate the various MRI appearances of hypoxic ischemic encephalopathy in term and preterm neonates and
to correlate the MRI appearances with clinical outcome.
Materials and Methods: All neonates with history of birth asphyxia, referred for MRI examination to the Department of Radio-Diagnosis, K. R.
Hospital attached to Mysore Medical College and Research Institute, during January 2018 to January 2019. All MRI scans were performed on
GE optima MR360 1.5 Tesla. Sequences used were T1W axial, T1 FLAIR axial, T2W axial, T2 FLAIR axial, T1W sag, T2W coronal, T2W GRE
axial, DWI axial and ADC maps.
Results: 30 babies with clinically suspicion of HIE and positive ndings on MR imaging were evaluated in our study. Out of 30 babies, 18 were
term and 12 babies were preterm. Periventricular luecomalacia is most common MRI pattern in preterm and central pattern in term neonates. 16
babies had abnormal developmental outcome at 6 months follow up study. 16 babies with diffusion restriction in corpus callosum, 12 had
abnormal outcome. 7 out of 10 babies with loss of normal signal in internal capsule had abnormal outcome. Babies with diffusion restriction in
basal ganglia had gross developmental delay.
Conclusion: MRI is the modality of choice for evaluation of HIE because of excellent gray – white matter resolution, well-depiction of
myelination pattern and multi-planar imaging capabilities. There is a strong relation between the MRI appearances of birth asphyxia and the
clinical outcome. Therefore MRI has a strong role in prognosticating lesions.

Published: May 2021

Fractal
behavior and long-range dependence are widely observed in measurements and
characterization of traffic flow in high-speed computer networks of different
technologies and coverage levels. This paper presents the results obtained when
applying fractal analysis techniques on a time series obtained from traffic
captures coming from an application server connected to the Internet through a
high-speed link. The results obtained show that traffic flow in the dedicated
high-speed network link have fractal behavior when the Hurst exponent is in the
range of 0.5, 1, the fractal dimension between 1, 1.5, and the correlation
coefficient between –0.5, 0. Based on these results, it is ideal to
characterize both the singularities of the traffic and its impulsiveness during
a fractal analysis of temporal scales. Finally, based on the results of the
time series analyses, the fact that the traffic flows of current computer
networks exhibit fractal behavior with a long-range dependency is reaffirmed.
Everything You Always Wanted to Know About Embedded Trace
Authors: Preußer Thomas , Gautham Smitha , Rajagopala Abhi , Elks Carl , Weiss Alexander
Published: May 2021

Decades of advances in computer architecture, software-intensive applications and system integration have created significant challenges for embedded systems designers and test engineers. Intrusive software instrumentation and breakpoint-based debugging are often viewed as the primary options for observing operational system internals. This narrow sight creates complicated test flows and convoluted debugging procedures. Modern embedded computing systems offer Embedded Trace as the technological answer to the encountered observability conundrum. Although an integral part of virtually all modern processors, it is frequently overlooked. Its technical foundations are little known to application engineers, test engineers, and project managers. This article explains Embedded Trace as an essential technology in the testing and debugging toolbox. It highlights its capabilities, limitations and opportunities.
Tempo e aspetto nella narrazione in ceco in una prospettiva diacronica
Authors: Esvan François
Published: May 2021

Regarding the historical present in Czech narrative the author proposes to distinguish three main modes: (i) the narrative present, which follows the same aspectual opposition system of the past tense narration mode; (ii) the tabular present, which neutralizes the aspectual opposition in favour of the imperfective aspect; (iii) the complementary distribution, which alternates past perfective and present imperfective. This assumption allows to reconsider the hypothesis of a trend to neutralize aspectual opposition in the historical present in Czech (Bondarko 1958).
Cancellazione dei riflessivi e diatesi media in russo
Authors: Garzonio Jacopo
Published: May 2021

The author discusses the distribution of the reflexive anaphora sebja and the middle voice affix -sja/-s’ in Russian. The Russian data are discussed assuming that in languages where the middle voice morphology can encode reflexivity, anaphors can be canceled in standard object position, where Accusative Case is assigned. This entails that direct object anaphors, when realized, are not in the structural position where they receive Accusative Case; it is argued that they can surface in Focus positions. The final part of the paper is dedicated to the analysis of the formal status of the middle voice affix.

introducción a las bases de Groebner
Authors: Gomez Gutierrez Vinicio
Published: May 2021

En este artículo nos proponemos dar una introducción elemental a las bases de Groebner, lo suficientemente accesible para que estudiantes de las ciencias físico-matemáticas y de las ingenierías puedan utilizar esta herramienta en sus cursos de cálculo. Por poner un ejemplo, en el estudio de multiplicadores de Lagrange pueden aparecer sistemas de ecuaciones polinomiales en varias variables. A diferencia de los sistemas de ecuaciones lineales, no son tan conocidos métodos para resolver dichos problemas. Esperamos contribuir a la difusión de una parte del álgebra que simplifica tanto la teoría como la práctica de la resolución de sistemas de ecuaciones polinomiales. Cabe mencionar que las aplicaciones de las bases de Groebner van mucho más allá de resolver sistemas de ecuaciones, pero en este artículo las presentaremos desde este punto de vista. Esperamos, por añadidura, despertar la curiosidad para acercarse al álgebra, esa parte de las matemáticas cuya belleza no se ve con los ojos.

La presente investigación tiene como objetivo caracterizar los procesos de enseñanza y de gestión utilizados por los promotores culturales para el fortalecimiento del patrimonio cultural de seis centros de cultura de la comunidad yaqui de Sonora: Loma de Guamúchil, Tórim, Pótam, Belém (Pitahaya), Ráhum y Huírivis. Para ello se desarrolló un diseño de investigación con un enfoque cualitativo y alcance descriptivo financiado por el Programa de Fomento y Apoyo a los Proyectos de Investigación (PROFAPI) del Instituto Tecnológico de Sonora. Se entrevistó a los promotores culturales que habitan en la misma comunidad en junio del 2019. El instrumento estuvo compuesto por 19 preguntas dividido en cuatro categorías: función del centro de cultura, enseñanza aprendizaje, financiamiento y estrategias para la salvaguardia del patrimonio cultural. Se encontró que en cada pueblo es el único espacio de esparcimiento y de formación artística. Es empleado para impartir talleres de arte tradicional con el objetivo de fortalecer la preservación del patrimonio cultural de la comunidad yaqui: clases de bordado, lengua cahíta, danza de venado, clases de violín, guitarra popular, dibujo, creación de cabezas de venado con papel, entre otras. No cuentan con una fuente económica permanente para la compra de materiales y generación de nuevos proyectos por lo que dependen, principalmente, del Programa de Apoyo a las Culturas Municipales y Comunitarias (PACMyC). También utilizan dinero propio para adquisición de consumibles. De manera esporádica reciben donaciones en especie. Los centros de cultura tienen una función clave en la generación de lazos entre los músicos y danzantes tradicionales de los ochos pueblos yaquis, ya que prestan las instalaciones para realizar los encuentros de gastronomía, música popular, pascolas y venados, desde su creación en los años ochenta, coordinados por el Centro de Culturas Populares e Indígenas de Cajeme y la Dirección General de Culturas Populares, Indígenas y Urbanas.

Background. Spain is one of the European countries most affected by the COVID-19 pandemic. Epidemiologic studies are warranted to improve the disease understanding, evaluate the care procedure and prepare for futures waves. The aim of the study was to describe epidemiologic characteristics associated with hospitalized patients with COVID-19. Methods. This real-world, observational, multicenter and retrospective study screened all consecutive patients admitted to 8 Spanish private hospitals. Inclusion criteria: hospitalized adults (age≥18 years old) with clinically and radiologically findings compatible with COVID-19 disease from March 1st to April 5th, 2020. Exclusion criteria: patients presenting negative PCR for SARS-CoV-2 during the first 7 days from hospital admission, transfer to a hospital not belonging to the HM consortium, lack of data and discharge against medical advice in emergency departments. Results. One thousand and three hundred thirty-one COVID-19 patients (medium age 66.9 years old; males n= 841, medium length of hospital stayed 8 days, non-survivors n=233) were analyzed. One hundred and fifteen were admitted to intensive care unit (medium length of stay 16 days, invasive mechanical ventilation n= 95, septic shock n= 37 and renal replacement therapy n= 17). Age, male gender, leukocytes, platelets, oxygen saturation, chronic therapy with steroids and treatment with hydroxychloroquine/azithromycin were independent factors associated with mortality. The proportion of patients that survive and received tocilizumab and steroids were lesser and higher respectively than those that die, but their association was not significant. Conclusions. Overall crude mortality rate was 17.5%, rising up to 36.5% in the subgroup of patients that were admitted to the intensive care unit. Seven factors impact in hospital mortality. No immunomodulatory intervention were associated with in-hospital mortality.

Пренатальный период имеет решающее значение для развития нервной системы. Несмотря на то, что марганец является эссенциальным элементом, его избыточное воздействие может приводить к негативным постнатальным последствиям. Изучено пренатальное влияние сульфата марганца на концентрацию ацетилхолинэстеразы в организме крыс в двух поколениях. С этой целью самки крыс линии Wistar в течение 28 дней до гестации и в период гестации (20–26 дней) в дополнение к основному рациону получали сульфат марганца в суточной дозе 1433 мг/кг. Молодое потомство первого поколения тестировалось на выявление поведенческих расстройств с по- мощью стандартизированных поведенческих тестов, по результатам тестов были отобраны самцы с наибольшими отклонениями. Самок из первого поколения в дальнейшем использовали для получения второго потомства, из которого также были отобраны самцы с поведенческими нарушениями. По достижении 18-недельного возраста у отобранных животных осуществлялся забор крови для определения уровня ацетилхолинэстеразы. Также оценивалось влияние перорального воздействия марганца на организм самок-матерей. Исследование установило, что в сыворотке крови самок крыс, подвергавшихся непосредственному воздействию сульфата марганца, наблюдалась тенденция к более высоким уровням ацетилхолинэстеразы. Статистически значимые изменения уровня данного фермента отмечались у животных первого поколения: значение первого квартиля у них было на 22 % больше значения третьего квартиля группы, которая не подвергалась пренатальному воздействию (p = 0,012). У животных второго поколения прослеживалась тенденция к более высокой концентрации ацетилхолинэстеразы в крови относительно интактных животных. Таким образом, исследование продемонстрировало, что сульфат марганца в пренатальный период оказывает влияние на концентрацию ацетилхолинэстеразы не только в материнском организме, но и у потомства в нескольких поколениях.

Published: May 2021

The research involved 479 schoolchildren living on the territory of the Khanty-Mansi Autonomous Okrug – Yugra (KMAO – Yugra). Two groups were singled out: the Khanty and 1st and 2nd generation descendants of newcomers. The following parameters were studied: blood pressure, heart rate, double product, and index of functional changes; the frequency of deviations from standard values was identified. In addition, the dominant type of circulation was determined. The analysis of the children’s circulatory system parameters revealed some ethnicity-related features. It was established that Khanty children have higher aerobic capacity of the cardiovascular system and lower blood pressure than newcomers’ descendants. Blood pressure deviations from the norm (high blood pressure in girls and arterial hypertension in boys) were statistically more common in newcomers’ descendants. Virtually one in two children had heart rate exceeding the normal values. Moreover, we observed increased stress of the cardiovascular system in the group of newcomers’ descendants (in girls aged 12–15 and boys aged 14–17 years) which was indicated by higher values of double product and index of functional changes. Hyperkinetic type of circulation was predominant in both groups, being, however, more frequent in Khanty children. The revealed features of the cardiovascular system in children of different ethnic groups living in KMAO – Yugra highlight the importance of developing regional and ethnic standards for an objective evaluation of children’s health.

This paper analyses environmental factors and their influence on the human body in the Far North. The cold factor is considered separately. It is noted that adaptation to extreme environmental factors in the north resembles adaptive processes taking place in the body under stress. The article describes the phenotypic approach to preventing non-communicable diseases in the population based on the theory of adaptation, control theory, theory of functional systems and system approach. We suggest using a predictive model of the body in the form of an anatomico-physiological structure reflecting grouping of interacting organs and tissues by their physiological functions. The model is represented by the reaction norms of the body’s systems and by the rules of their interaction. With its help, one can identify the predisposition of the body’s systems to destruction and the corresponding cause-and-effect relationships in the body, as well as devise a personal algorithm for health preservation and carry out vocational selection. The predictive properties of the model are based on the manifestations of the adaptive response to environmental stress factors. The recommendations are preventive in nature and are aimed at stimulating the individual’s involvement in his/her health protection. Methods of influencing the homeostatic regulation of the body and increasing the capabilities of the immune system in the north are proposed, i.e. technologies for restoring the body’s circadian rhythm as well as activating the living environment and drinking water in order to prevent chronic non-infectious diseases. The suggested predictive model of the body contributes to the development of a general theory of adaptation and a general theory of pathology. The considered approach to health preservation is compatible with telemedicine and e-health technologies and can therefore make adequate medical services available to the population of the Far North, in particular to those living in remote areas.

Методы редактирования генетической информации и возможность управлять ей позволили добиться значительного прогресса в медицине, в частности в изучении патогенеза различных заболеваний, в т. ч. сердечно-сосудистой этиологии. Один из методов редактирования – технология CRISPR/Cas9. CRISPR – это ряд последовательностей генома бактерий и других прокариот, тогда как Cas9 – это эндонуклеаза, непосредственно разрезающая целевую чужеродную последовательность. Сердечно-сосудистые заболевания являются одной из лидирующих причин смерти во всем мире. Достаточно большое количество сердечно- сосудистых заболеваний, таких как гипертрофическая кардиомиопатия, синдром удлиненного и укороченного QT-интервала, имеют наследственную природу. Данный факт значительно осложняет процесс лечения таких патологий. Тем не менее это же позволяет применять метод CRISPR/Cas9 в целях обнаружения и редактирования генов для дальнейшего облегчения клинической картины. Однако генетическая инженерия и ее методы в целом являются достаточно малоизученной областью. Более того, несмотря на то, что существует значительное количество экспериментальных работ о воздействии CRISPR на сердечно-сосудистую систему, не хватает комплексных обзоров, которые бы отражали все положительные и отрицательные аспекты использования CRISPR/Cas9 в терапии наследственных сердечно-сосудистых заболеваний. В данной статье рассмотрены различные варианты применения CRISPR-редактирования непосредственно в клинической практике, а также в моделировании сердечно-сосудистых заболеваний. На основе полученных данных был сделан вывод о том, в какой из областей применение CRISPR/Cas9 является наиболее целесообразным и показывает наилучший результат.

This paper presents data on the results of the assessment of postural balance in older women. The study was conducted using the computer-aided stabilometric complex Balance Manager with the participation of 186 women aged 60–74 years. At the time of the research, the subjects were mobile and did not use any additional support when walking. Based on the identified percentile intervals, the critical values of postural balance parameters that can be considered as indicators of the developing risk of falls were determined and recommendations for its prevention were devised.

PROSPECTS FOR EXPANDING SOUTH KOREA-UZBEKISTAN INVESTMENT COOPERATION
Authors:   Tashkent State University of Oriental Studies Uzbekistan, YOZIEV Golibjon
Published: May 2021

More and more countries are seeking to liberalize their economies to attract foreign direct investment (FDI) flows. In this regard, the most important question for these countries is not only to reform, but also how to carry out reforms. In this regard, the Korean experience is a particularly interesting example. Because its reforms, which began in the 1990s, were rapid and farreaching. The purpose of this study is to study deeply the experience of the Republic of Korea in attracting foreign direct investment. By studying the Korean experience, we will try to find answers to the questions: What were the main obstacles and what were the main driving forces? How did FDI liberalization compare with other reforms (trade and regulatory reform, foreign investment policy)? Understanding the Korean experience is useful for other countries, especially for Uzbekistan, which still has high levels of regulatory constraints, as measured by the FDI Index. In recent years, Uzbekistan has been striving to attract more investment and realizes that it is necessary to reform its investment regime, but does not know how best to proceed.

One of the biggest events in international political history at the end of the 20th century was end of the Cold War due to the dissolution of the Soviet Union. With the collapse of the Soviet Union in December 1991, the Cold War system, led by the US and the Soviet Union as the two main axes, disappeared into history, dramatically changing the international situation and creating new independent states in the international community. In the past, as the protagonist of the Silk Road civilization, it was a channel of trade and culture, linking the East and the West, but as members of the former Soviet Union, Central Asian countries whose importance and status were not well known have emerged on the international stage in the process of forming a new international order. After independence, Central Asia countries began to attract attention from the world as the rediscovery of the Silk Road, that is, the geopolitical importance of being the center of the Eurasian continent, and as a treasure trove of natural resources such as oil and gas increased.

The article analyzes the causes, and consequences of the Aral Sea catastrophe and considers initial results of regional and international cooperation aimed at cushioning urgent problems, especially those emerging in the Aral Sea Basin disaster zone. The Aral, one of the world’s largest lakes, to dried up and almost disappeared within the lifespan of a single generation. Mismanagement of water resources and cotton monoculture led the Aral to a point of irreversibility by the FSU’s break-up. After dissolution of the FSU, the problem took on an international character, with multifaceted implications for keeping negative effects on sustainable human development as attempts were made to preserve at least some fragments of the Aral. Joint national, regional and international efforts initiated by new Uzbekistan situation in recent 4 years has been step by step improving. Cooperation of Uzbekistan with Republic of Korea on the Aral Sea Problems also serves for this purpose.
