Authors: Mellali Sarah , Haoud Khadidja , Bouguetaia Mohammed el amin , Diaf Mustapha
Published: May 2020

Objective: The aim of our study was to identify modifiable risk factors for miscarriage and to estimate the preventable proportion of miscarriages that could be attributed to these risks. Materials and Method: We carried out an epidemiological study of pregnancy loss in the Sidi Bel Abbes region from 2010 to 2015, with a total of 54720 livebirths and 4349 of spontaneous abortions (SA). The risk of spontaneous abortion related to the fetal loss age, maternal age; parity and previous spontaneous abortions was studied. Results: The rate of spontaneous abortions varies between 7% and 9% and appears to remain constant over the six years, with an average incidence of 8%. We also observed a significant increase in the incidence of SA with the increase in maternal age. 77% of SA occurred before 12 weeks of gestation. The peak incidence occurred during the second month of pregnancy, between 6th and 10th, the rate of AS is the highest among primigests. The incidence of SRA in our study is within the range suggested by these different studies, with a SRA rate of 5%. Fetal loss is high in women in their late 30s or older, irrespective of reproductive history. Conclusion: The fact remains that the risk factors remain the same, namely, the increase in maternal age (inducing an increase in chromosomally unbalanced designs) and primigestity.

Published: May 2020

Hydroxychloroquine (HCQ) as a drug grabbed serious attention of whole world in dealing with COVID-19 pandemic. Recently some in-vitro and in-vivo study showing possible inhibition of SARS-CoV-2 by use of HCQ. However at the same time, some case studies showing NO clinical benefit/ poor clinical outcome with substantial detrimental adverse effects by use of HCQ in treatment of coronavirus disease-2019. Thus, the HCQ use (in COVID-19 treatment) is of current international interest, although a consensus has not yet been reached. More evidences are still required to prove efficacy of HCQ against COVID-19. In view of this, the present review highlights the current ongoing research related to use of HCQ in treatment coronavirus disease-2019. The present review will discuss the possible anti-viral mechanism of HCQ, prophylaxis strategy and effect of HCQ against SARS-CoV-2 virus in-vitro study. Further this review also summarizes and debates all available clinical trials/ case studies of HCQ use against COVID-19 (with clinical outcome). Finally possible detrimental adverse effects are also discussed considering the public health and pharmacovigilance concern.

What lies behind the gender wage gap in Serbia?
Authors: Anic Aleksandra , Krstic Gorana
Published: May 2020

Large gender inequalities have persisted in the Serbian labour market. One of
the key indicators of labour market inequality is the gender pay gap. This
paper examines the gender pay gap in Serbia based on data from the Survey of
Income and Living Conditions. Our findings show that on average women earn
far less than men, a gap that has increased slightly over time. The paper
offers an in-depth analysis of this gender pay gap in Serbia by decomposing
the gender pay gap into an explained part related to difference in
characteristics and an unexplained part related to differences in returns
attributable to these characteristics. In addition, it provides an estimate
of selection effects on the gender pay gap using an innovative methodology
that corrects for sample selection bias.

Authors: Volkov S.S. , Nosov A.A. , Aleksandrova S.A.
Published: May 2020

Введение. Исследование заключалось в морфометрии легочного клапана человека с детальным изучением его геометрии. Цель: получить новые знания и обсудить возможность их применения в сердечно-сосудистой хирургии. Материал и методы. Морфометрия клапана легочной артерии проводилась в двух независимых группах: в 1-й группе методом аутопсии нефиксированных сердец, во 2-й методом прижизненных измерений на основании данных компьютерной томографии с внутривенным введением контрастного препарата. Результаты. В обеих группах получены сопоставимые результаты. Установлено, что геометрия здорового клапана легочной артерии имеет пропорцию золотого сечения, при которой отношение суммы диаметра (d) и высоты (h) клапана к его диаметру равно отношению диаметра к высоте и стремится к постоянному значению числа Фибоначчи (1,618). Аналогичная закономерность обнаружена для ширины створки (l) ивысоты клапана. Зависимость частей пропорции имеет сильную связь и нелинейный характер. На основании полученных данных разработаны и запатентованы формулы лекал для изготовления медицинских изделий с искусственным легочным клапаном (hd/1,618 lh1,618). Заключение. Морфометрия клапана легочной артерии может быть выполнена прижизненно с помощью метода компьютерной томографии. Геометрия легочного клапана содержит пропорции золотого сечения. Новые знания могут быть востребованы сердечно-сосудистыми хирургами при выполнении реконструктивных операций на выводном отделе правого желудочка, врачамирентгенологами и разработчиками медицинских изделий для сердечно-сосудистой хирургии.
Коронарное шунтирование на работающем сердце с использованием композитного кондуита при остром коронарном синдроме без подъема сегмента ST и аневризматическом поражении коронарных артерий

Статья посвящена особенностям выполнения операции коронарного шунтирования на работающем сердце у пациента с ишемической болезнью сердца с высоким хирургическим риском и острым коронарным синдромом (ОКС) без подъема сегмента ST и с аневризмами коронарных артерий на фоне множественного стенозирующего поражения коронарных артерий. Общепризнано в настоящее время, что малоинвазивная реваскуляризация миокарда (МИРМ) может быть рекомендована для использованиями только опытными хирургами, чтобы получить оптимальные результаты. В последнее время было показано, что МИРМ дает хорошие непосредственные результаты у пациентов с высоким риском, в частности у больных пожилого возраста, с почечной недостаточностью, с заболеваниями легких, при нарушении функции левого желудочка, с множественными сопутствующими заболеваниями. Однако использование МИРМ у пациентов с острым коронарным синдромом остается проблематичным с учетом повреждения, а также при выраженном дефиците перфузии миокарда. При ОКС на фоне аневризматического расширения коронарных артерий для реваскуляризации миокарда с высокой вероятностью может потребоваться операция коронарного шунтирования, поскольку чрескожное коронарное вмешательство связано с более высоким риском перфорации сосудистой стенки или образования новой аневризмы в этой ситуации. В представленном клиническом случае описанный подход позволил избежать вероятных осложнений. У пациента со стенозирующим и аневризматическим поражением коронарного русла и ОКС без подъема сегмента ST был гладкий послеоперационный период после МИРМ с использованием композитного шунта из левой внутренней грудной артерии в сочетании с венозным шунтированием.
Особенности анестезиологического обеспечения операций на сердце в Госпитале Джонса Хопкинса, США: отчет о научной стажировке
Authors: Diasamidze K.E.
Published: May 2020

Ранняя активизация широко используемый термин. Cущность метода составляет комплекс анестезиолого-реанимационных мер, обеспечивающих максимально быстрое прекращение искусственной вентиляции легких (ИВЛ) и экстубацию трахеи, что является ключевым моментом послеоперационного восстановления физической активности больного. К преимуществам данного подхода относится интенсификация лечебного процесса, уменьшение числа осложнений, связанных с продленной ИВЛ, укорочение длительности пребывания пациента как в отделении реанимации и интенсивной терапии (ОРИТ), так и в стационаре в целом и, следовательно, значимое удешевление лечения. Но вместе с тем до настоящего времени нет однозначного положительного решения, как и протокола по применению данной методики в кардиохирургии. В литературе описан и положительный, и отрицательный опыт. В статье представлен опыт ранней активизации больных в Госпитале Джонса Хопкинса, изученный автором во время научной стажировки.

The paper considers self-regulation as an arbitrary mental process aimed at improving individuality. The authors analyze the formation of self-regulation as the personality’s ability to set goals and to make life projects in accordance with the time perspective, as well as a basis for the formation of personal role and motivation for learning. To conduct this diagnosis, we took the following diagnostic tools: in order to study students' self-regulation, we used the “Methodology for determining styles of behavioral regulation” (V.I. Morosanova, Ye.M. Konoz), as well as the Test Questionnaire “The study of volitional self-regulation” (A.V. Zverkov, E.V. Eidman). At the second stage of the study, we applied methods to determine the level of anxiety. Typical ways to respond in complex conflict situations were identified. The authors rely on the concept of V.S. Merlin’s personality, which is revealed through understanding a person as an integral individual. The process of personal development is in expanding relationships between properties related to different levels of individual’s organization. Relationships of person’s features in a social group are evaluated. When comparing groups with high and low levels of self-regulation we found the one in which the respondents’ personality is more harmonious. After analyzing the results of the study, the authors presented a theoretical model of the program for the formation of students' self-regulation.

“Operar es vincular”
Authors: Operar es Vincular Programa Solidario Remoto en la Salud Mental
Published: May 2020

Es la primera vez en la historia moderna del país que se suscita un confinamiento social generalizado de la población. Muchísimas personas, siendo o no pacientes de servicios o prestadores de salud mental se encuentran aislados. Los profesionales y técnicos también. El Estado no puede asumir en soledad el gigantesco fenómeno del aislamiento, y se enfoca en la no transmisión del virus. 

Un grupo de organizaciones, a través de diversos organismos civiles y movimientos sociales del ámbito del quehacer psicosocial nos hemos agrupado y organizado para cubrir una función de contacto remoto al efecto de escuchar, sostener, contener y vincular personas que se encuentren en situación de mayor vulnerabilidad. 

En este artículo se presenta una propuesta de implementación de un conjunto de dispositivos para el cuidado de la salud mental de la población de nuestro entorno, en una gestión masiva, basada en la conjunción y articulación de personas que requieren de un servicio de atención profesional y un equipo de voluntarios/as, profesionales del ámbito de la salud mental, capaces de intervenciones centradas en un primer foco de captación y eventual derivación, si fuera preciso, a organismo públicos competentes. Para ello, nos apoyaremos en la construcción que viene desarrollando el Programa Solidario de Abordaje Remoto de la Salud Mental “Operar es Vincular” (PROSAR).

Imunidade na Infeção pelo SARS-CoV-2: O que Sabemos
Authors: Nunes Silva Cláudio , Ceia Filipa , Tavares Margarida
Published: May 2020

Sobre a pandemia provocada pelo SARS-CoV-2, muito conhecimento tem sido produzido e dado a conhecer, mas muitas dúvidas permanecem por esclarecer acerca da sua interação com o ser humano, nomeadamente sobre se a resposta imune contra este novo coronavírus humano é protetora a longo prazo e qual a possibilidade de re-infeção. A COVID-19 pode assumir diferentes espetros clínicos, desde infeções assintomáticas até formas graves da doença, que resultam da inter-relação entre a patogenicidade própria do vírus e a resposta imune do hospedeiro. Esta revisão foca-se na imunologia da infeção, reunindo não só o conhecimento acumulado com as epidemias associadas ao SARS-CoV e MERS-CoV, mas também o que já se sabe sobre o SARS-CoV-2. Este conhecimento é fundamental e tem implicações quer para o controlo e prevenção da doença quer para o seu diagnóstico e tratamento.
Cryptanalysis of the chaotic oscillator based random number generator for bank authenticator device
Authors: ERBAY Celal
Published: May 2020

In this study, cryptanalysis of a non-equilibrium point chaotic oscillator based random number generator (RNG) that developed as a high security authentication tool for internet banking systems is presented. The security vulnerabilities of the algorithm that generates random bits by using the digits of floating-point numbers have been analyzed and the convergence has been shown by using the master slave synchronization scheme. Simulation and numerical results of the proposed method confirm that both next bit and output bit stream are predictable. Therefore, producing random numbers by using such an algorithm for the authentication tool is very unsecure and master slave synchronization cryptanalysis method is useful to validate chaotic systems.

In Spain between 2010 and 2011 there has been a major financial restructuring, which has led to the virtual disappearance of savings banks through mergers and subsequent change in ownership structure becoming banks. This major restructuring has been promoted by the Bank of Spain, as an outlet for that financial institutions subsisted to the crisis that affected them.This paper analyzes the banks and savings banks the Spanish financial system during the four years prior to the beginning given the financial restructuring of 2010. The aim is to check whether there are differences in profitability for reasons of size and form of ownership of the entity (savings banks, banks). The results show that the increase in size and bankarization under the auspices by the Bank of Spain is an appropriate strategy for resolving the current financial crisis.
EXPERIMENTAL DETERMINATION OF CUTTING RESISTANCE STRENGTH AT ASPHALT CONCRETE DESTRUCTION WITH A SINGLE CUTTING ELEMENT
Authors: Furmanov D. V. , Chizhov V. S. , Lysakov N. E.
Published: May 2020

Introduction. The article is devoted to the research results on cutting resistance of a road asphalt concrete in the process of the removal of worn coatings by the working elements of milling machines. The relevance of the work is due to the occurring of new brands of asphalt concrete alongside with the use of new types of cutting elements, for which it is difficult to predict the load on the working element when solving the problems of designing new ones and substantiation the operating conditions of the current machines. The purpose. The objective of the study of the interaction of a single cutting element of a road mill with a material at the best fit of speed and geometric parameters of a cutting process with real machines is solved.

Materials and methods. The experimental work was carried out by determining the tangential component of a cutting resistance strength, as well as the work of this strength on a pendulum desk using a unit recording equipment. Four different types of asphalt concrete were being destroyed. A two-factor experiment was conducted for each type of the material. The tangential components of a cutting resistance strength depending on the thickness of the cut chips and the temperature of the material were evaluated.

Results. As a result of the experiment, the data were obtained that make it possible to reasonably determine the loads on the teeth of road milling machines, to determine a power capacity of the process and the drive power of the working element. It was found that the growth of the tangential component to a cutting resistance strength occurs quite intensively alongside with an increase in the thickness of the cut chips, only at the initial stages of the penetration of the cutter. With an increase in the thickness of the cut chips, the growth of the tangential component to a cutting resistance strength does not occur so intensively. In all cases the temperature of the material has an impact on the value of a cutting resistance strength, but this effect is less significant for asphalt concrete with a higher crushed stone content.

Discussion and conclusion. The obtained data make it possible not only to determine the tangential strength to cutting resistance on the cutting elements of the working element of the milling machine, but also to find rational ways to place the cutting elements on the working element, as well as to determine the rational operation conditions of the current and new machines. This is possible when using the results in a mathematical model that describes the operation of the milling working element as a whole.

DETERMINATION OF THE THROUGHPUT CAPACITY OF STOP POINTS OF URBAN PUBLIC TRANSPORT
Authors: Fadeev A. I. , Fomin E. V. , Alhusseini S.
Published: May 2020

Introduction. One of the most important parameters of the transport system is the capacity of line, which in urban public transport system is usually determined by the stop points throughput capacity. When determining the throughput capacity of stop points, it is necessary to consider the random nature of the transport flows at the stop and the process of boarding and alighting passengers. In this work, the stop point is considered as a multi-channel single-phase queuing system (QS). On this basis, an approach to determining the throughput capacity of stop points in urban passenger transport is proposed and justified.

Materials and methods. Two mathematical models of a stop point as QS are considered: analytical and simulation. Based on the obtained analysis results from these models, recommendations are offered for calculating the actual throughput capacity of a stop point.

Results. In this article, as example a specific stop points are taken, to evaluate the performance of the proposed mathematical models and formulate recommendations to determine its throughput capacity.

Discussion and conclusion. The proposed procedure for determining the stop points throughput capacity, consisting of identifying critical stop points with the highest passengers traffic, determining the service process parameters of fleet, and calculating the probability of queue occurrence, allows to set the maximum traffic intensity for the lines of urban public transport.

Research on the Status Quo and Countermeasures of Socialized Service Based on University Library
Authors: Hu Qing
Published: May 2020

With the continuous improvement of China's social and economic level, education, especially college education, has been highly valued by people and has achieved certain results. For the development of colleges and universities, library construction is an important part of it and to a certain extent promotes the stable development of colleges and universities. Judging from the actual development of domestic university libraries, many university libraries have gradually entered the path of socialized service. Due to the profound influence of traditional education mode and test-oriented education concept, many university libraries in China are currently developing socialization. There are some problems that need to be solved in the service work process. The existence of these problems makes many domestic university libraries unable to play their own roles and individual values, and it also seriously affects the rapid development of China's college education. Based on this situation, the author makes an in-depth analysis and discussion on the status quo and optimization strategies of the socialization service of university libraries in China, hoping to provide reference for the social service work of college libraries nationwide.

These were compared with the variables obtained before the implementation of RRTs (from 1st November 2018 to 31st August 2019 vs. 1st November 2017 to 31st August 2018).

Results and discussion:
RRTs made 626 surveillance visits to patients with serious conditions staying at hospital wards, 266 scheduled visits to 89 patients transferred from the ICU to other wards and 126 interventions in response to calls from different wards. The number of patients transferred from the hospital wards to the ICU decreased from 125 to 90. The number of deaths in the ICU decreased from 20 to 13.

Conclusions:
The evaluation of the 10-month implementation period for this project encourages to keep RRTs operational. The interviewed staff admitted that the safety of inpatient care increased along with more meticulous supervision over patients needing intensive care.
The role of cognitive and personality characteristics in timely microcredit repayment: Evidence from a survey conducted by Provident, Mexico
Authors: Di Giannatale Sonia , Ventosa-Santaulària Daniel , Roa Maria José , Elbittar Alexander , Trujano Darío
Published: May 2020

Sustainability of microfinance institutions depends, among other factors, on having appropriate repayment levels. This article's contribution to the existing literature is the analysis of the role of a personality trait named "grit" in individual microcredit repayment decisions, alongside cognitive characteristics and time and risk preferences. This study is based on a survey of a sample of clients at 'Provident México', a formal microfinance institution that provides personal loans in vulnerable communities in Puebla, Mexico. We find evidence that, generally, older individuals possessing higher levels of grit and a tendency toward short term present bias are more likely to show no delays in loan repayments. Cognitive characteristics are inversely related to paying microcredits on time. Refinancing incentives does not play a key role in timely microcredit repayment, a result that is contrary to related literature but consistent with our finding that individuals in this sample that do not have delays in repayments are characterized by showing a short term present bias.

Sensibilidad y asimetrías ante choques de ingreso en el consumo privado de México, 1995-2017
Authors: Mendoza González Miguel Ángel
Published: May 2020

Esta investigación analiza con un enfoque poskeynesiano la sobre-sensibilidad y las asimetrías ante choques de ingreso del consumo privado y su desagregación en bienes duraderos, semi-duraderos, no-duraderos y los servicios en México para el período 1995-2017. Para estimar la sobre-sensibilidad se utilizan las metodologías de cointegración de Johansen-Juselius y el método de estimación FMOLS, sin sesgo de endogeneidad de Phillips y Hansen. Para las asimetrías se aplican las pruebas de Seo y Hansen-Seo de cointegración, con regímenes múltiples (cointegración-threshold) y modelos TVECM de vectores de corrección de error, con regímenes múltiples de Seo. Con los resultados se comprueba la existencia de sobre-sensibilidad del consumo privado y del consumo de la mayoría de los bienes por durabilidad (nacional e importado) y comportamientos asimétricos de régimen bajo, consistente con un escenario de crisis económica.

Authors: García-Domínguez Miguel , De La O-Espinoza Estivaliz Arizel , Cruz Muñoz Mario Ernesto
Published: May 2020

Antecedentes: El síndrome de Wiskott-Aldrich es una inmunodeficiencia combinada asociada al síndrome ligado al cromosoma X, que se caracteriza por eccema, infecciones de repetición y trombocitopenia. Otras manifestaciones son los trastornos autoinmunes como anemia hemolítica o púrpura trombocitopénica mediada por el sistema inmunológico y susceptibilidad incrementada a tumores malignos, como linfoma o leucemia.Caso clínico: Niño de siete años, con diagnóstico de síndrome de Wiskott-Aldrich, en quien se estableció tratamiento con gammaglobulina intravenosa, profilaxis antimicrobiana con trimetoprima-sulfametoxazol y fluconazol, así como prednisona y ciclosporina debido a anemia hemolítica y uveítis. De forma súbita presentó desviación de la comisura labial izquierda, por lo que fue hospitalizado. Los estudios indicaron aneurisma gigante de la raíz de la aorta, aorta ascendente, descendente y coronaria derecha, con sintomatología cardiaca insidiosa, por lo que fue referido al servicio de cirugía vascular.Conclusiones: La vasculitis en el síndrome de Wiskott Aldrich es poco común y suele ser asintomática en las fases iniciales, por ello debe realizarse evaluación cardiovascular anual para evitar complicaciones propias de un aneurisma, que pueden ser deletéreas en este tipo de inmunodeficiencia, en las cuales existe mayor riesgo de muerte por sangrado.
How to encourage “Togetherness by Keeping Apart” amid COVID-19? The ineffectiveness of prosocial and empathy appeals
Authors: Favero Nathan , Pedersen Mogens Jin
Published: May 2020

The COVID-19 pandemic is a major challenge facing societies around the world. Citizen engagement in “social distancing” is a key containment measure for curtailing the spread of the virus. But what kind of information should governments use for encouraging social distancing compliance? Using data from a pre-registered survey experiment among US residents (n = 1,502), we examine how five distinct COVID-19 information cues—which each appeal to prosocial motivation and empathy in varying degree—affect people’s willingness to social distance. We find no significant differences across experimental conditions in terms of (a) the duration that respondents are willing to maintain social distancing, (b) intended social distancing behavior, or (c) COVID-19-related attitudes and beliefs. Our findings should not necessarily discourage decision-makers from priming prosocial motivation and empathy as means for promoting social distancing, but they do suggest a current need for more engaging medium than simple textual messages for such appeals.

Foreshadowing the Future of Capitalism: Surveillance Technology and Digital Realism in Xu Bing’s Dragonfly Eyes
Authors: Zhang Ling
Published: May 2020

How has the development of surveillance technology and its normalized intervention into our social structures and daily lives impact our imagination of the future? Does the “total view” of the intense yet impassive gaze of surveillance cameras, combined with the mediated intimacy of social media videos, foreshadow deeper social alienation or the fulfillment of individual desire? In order to address such questions, I take the Chinese artist Xu Bing and his team’s film Dragonfly Eyes (Qingting zhi yan, 2017) and its surrounding media culture as a case study to demonstrate how surveillance footage and various modes of cinematic ontology, digital realism, and temporality work in a contemporary socio-political-medial context. Composed by Xu and a group of collaborators, Dragonfly Eyes is the only existing feature-length fiction film constructed completely from surveillance footage. As a highly reflexive film, Dragonfly epitomizes and embodies the precarious potentials of the digital future of capitalism, both invigorating and bleak, expressive and corrupt.

O presente estudo com o título “ O setting analítico na clínica cotidiana” consiste em
saber como o analisando pode dificultar seu tratamento no setting analítico. Elegeu
como objetivo entender a dinâmica psicanalítica e suas variações no setting
analítico. É uma pesquisa de natureza básica sendo que, quanto ao problema é
qualitativa e quanto aos objetivos é explicativa descritiva. Sobre os procedimentos
técnicos é bibliográfica. A respeito do método é hipotético dedutivo fundamentado
em Karl Popper. A construção de novos paradigmas trouxe como consequência a
necessidade de rearranjos e transformações nos tipos de interações entre os
indivíduos.Constatou-se que a psicanálise vem sofrendo sucessivas
transformações mas conserva a essência dos princípios fundamentados legados
por Freud. Este estudo contou com as contribuições de autores como Bion (1992),
Ferenczi (1919/1992), Freud (1895); Lacan (1988); Forbes (2004), Zimerman

ВУГЛЕЦЕПОГЛИНАЛЬНА ЗДАТНІСТЬ СОСНОВИХ ЛІСОВИХ НАСАДЖЕНЬ ЧЕРНІГІВСЬКОГО ПОЛІССЯ
Authors: Мороз В. В. , Никитюк Ю. А.
Published: May 2020

Згідно з підписаною Паризькою кліматичною угодою перед Україною постало завдання не допус-тити зростання глобальної середньої температури повітря більше 2,5 °C, аби уникнути збільшення посух, зникнення окремих видів рослин і тварин, всихань і захворювань деревних порід та ін. Для збе-реження та збільшення кількості природних поглиначів вуглецю науковці надають особливу увагу системі покращення управління лісовими, ґрунтовими та іншими природними ресурсами. Серед тридцяти головних лісотвірних порід в Україні сосна звичайна (Pinus silvestris L.) є найпоширенішою де-ревною породою, зокрема в Чернігівському Поліссі, її кількість становить 214,2 тис. га, що складає 61 % від усіх деревних насаджень. Для встановлення вуглецепоглинальної здатності соснових наса-джень Чернігівського Полісся в державних підприємствах: Городнянське ЛГ, Добрянське ЛГ, Корюківське ЛГ, Ніжинське ЛГ ми заклали тимчасові пробні площі (ТПП). Згідно з методиками П. І. Лакиди, А. А. Сторочинського, О. І. Полубояринова, А. С. Аткина, А. І. Кобзаря встановлено фітомасу соснових насаджень в абсолютно сухому стані та отримано конверсійні коефіцієнти, які дали змогу оцінити різницю між викидами СО2 та поглинанням вуглецю. Згідно з проведеним аналі-зом розподілу площ лісових ділянок під сосновими насадженнями в Чернігівському Поліссі щонайбі-льше займають соснові ліси IV категорії (експлуатаційні) їх частка складає – 64 %, тому їх вугле-цепоглинальна здатність є більшою. Проаналізовано кліматичні зміни за період 1968–2018 рр., вста-новлено тенденцію до зростання середньорічної температури повітря на 2,5 оС у регіоні досліджен-ня. З’ясовано, що соснові ліси Чернігівського Полісся щорічно поглинають 34,0 тис. т вуглецю з по-вітря, що приблизно становить 1,37–2,15 % від щорічних викидів вуглецю в атмосферне повітря, а це своєю чергою має позитивний вплив на стан навколишнього середовища в регіоні дослідження.
