Measuring congestion at road-diet reductions using probe vehicle data
Authors: Remache-Patino Bryan A. , Comeau Daniel J. , Brennan Thomas M. , Park Seri
Published: November 2022

Road diets provide a means to reduce traffic speeds and promote alternative travel modes within the United States. Throughout the state of New Jersey there are approximately 50 existing road diets with more planned. While research has shown that road diets improve safety, no defined means to measure their long-term impact on traffic flow were found. This paper explores some new and existing means for applying intelligent transportation techniques to quantify long-term congestion changes through commercial anonymous probe vehicle (APV) speed data, the annual average daily traffic and other factors. Two case studies are used to evaluate congestion performance metrics, analysing 8 million APV speed records. Although there are a number of variables to consider, this preliminary research establishes a base measure for evaluating the pre- and post-road-diet impact on traffic flow.

Abstract : This study focuses on the emerging technologies used in Augmented Reality (AR) and their role in the field of education. With this aim, 70 articles gathered from Scopus, Science Direct, Springer, Taylor Francis, and Web of science databases were examined. Analysis showed that the number of AR articles in educational environments have gradually increased over the years. AR is being most commonly used in science education (biology, physics and chemistry). The literature also highlights various advantages of AR when used in learning environments. It has been understood that the AR is an imminent learning tool and is lately gaining recognition and acceptance in the educational field. While marker-based AR was the key in most of the articles, it was implemented using mobile devices. The literature revealed that most articles examined their results using Quantitative methods. Our article emphasizes on the impact of AR in education, current technologies and its future scope. This paper also provides detailed analysis of the use of AR in engineering education highlighting that the most of the articles highlighted the use of marker-based AR, used non-probability sampling strategy and appliedmixed method for analysis. The findings of this study would help other researchers to identify potential direction for future research. Keywords : augmented reality; education; interactive learning environment; technologies of augmented reality; augmented reality integration.

Abstract : The recent pandemic COVID-19 has forced almost all governments in the glob to take stringent actions to counteract the spread of this new deadly various. In Jordan, the government introduced the Marshal Law and enforced lockdown of all activities in both of private and public sectors in the country including schools, universities and social gatherings. As a result, demand on the Internet increased sharply: working from home, on-line teaching and learning and on-line orders for different supplies. Such sudden and unexpected dramatic changes increased the load on the fragile existing network and available E-learning systems. In this study, online teaching process, in-house solutions for virtual coaching, in the faculties of engineering, was evaluated and analyzed, with focus on students' points of view. To achieve such goal, a structured questionnaire was distributed to engineering students from different levels and streams. Statistical analysis was conducted to determine the level of satisfaction ofstudents and testify how far the E-learning process was successful as compared with conventional classroom learning. It was concluded that students were not comfortable with this first experience related to online teaching, especially when it comes to specialized technical and practical courses as well as labs. Moreover, they faced serious problems in following up online lectures. This could be attributed to the fact that this is the 1st experience on distance learning and weakness in existing facilities and lack of awareness among students as well as staff members.

Abstract : The developments in the Engineering domain have risen at an unprecedented rate in the past three decades. New technologies emerge every year and find their use case in multiple industries, also impacting the higher education as a whole. The present ecosystem demands industry-ready graduates from higher education institutes. To meet this, inculcation of newly developed technologies in the engineering education domain is a must. The retention span of Millennials in the traditional classroom settings has lowered down, posing the biggest challenge in student learning outcome at the higher education level. To solve this problem, interactive and immersive technologies has played a significant role through the use of Augmented Reality (AR), Virtual Reality (VR), and Gamification in a modern classroom setting. These technologies are capable of being used online as well as offline, and promise to deliver an enhanced user experience. The use of such tools also improves the student engagement by virtue of interactive content during the classroom session. This results in improved student learning and motivation in various domains of higher education. This paper focuses on the engineering education domain and discusses the role of these technologies in improving student understanding of intricate concepts of various engineering disciplines. A study of research papers presenting different digital learning platforms developed using these technologies from 2017 to 2021 was done, and it was concluded that the trends and technologies discussed in this paper have been tested and proven to be beneficial in engineering education. Further, developing a low-cost learning system using immersive and interactive technologies, and upgrading the present classroom set-up and skill set of instructors to make them significantly capable of utilizing the benefits offered by these technologies is yet to be achieved.

ON THE ROLE OF GRIGORY ORDZHONIKIDZE IN THE INNER-PARTY STRUGGLE OF THE 1920s
Authors:   Lomonosov Moscow State University, Apalkov D. I.
Published: November 2022

The article examines the role of Grigory Ordzhonikidze in the inner-party struggle of the 1920s. The purpose of the article is to determine what position Ordzhonikidze held at different stages of the inner-party struggle. The transcripts and other documents of the leadership of the Bolshevik Party, stored in the Russian State Archive of Socio-Political History (RGASPI), became the basis for the research. Contrary to the popular opinion in historiography, the author states that Ordzhonikidze acted independently and was not an obedient satellite of Joseph Stalin during the inner-party struggle. After being appointed the Chairman of the Central Control Commission, he tried to some extent to alleviate the severity of political conflicts and prevent the use of harsh punishments against Stalin's opponents. There is a version in historiography according to which in 1928, during the conflict between Stalin and the Rykov – Bukharin group, Ordzhonikidze initially supported the «right wing» of the Politburo, but then suddenly revised his views and supported Stalin’s position. Based on the analysis of archival documents, the author concludes that this statement is invalid. At the same time, Ordzhonikidze, although he was on friendly terms with Stalin and shared his views on the peasant question had a conciliatory attitude and was inclined to seek a compromise with the «right». Ordzhonikidze's conciliatory attitude disappeared after the Trotskyists published a recording of a secret conversation between N. I. Bukharin and L. B. Kamenev. This compromising material formed among the Bolshevik leadership the perception of the «right wing» of the Politburo as an opposition group capable of splitting the «monolithic unity» of the party. For this reason, at the beginning of 1929, when the supreme party court over the «right» was held at the joint meetings of the Politburo and the Presidium of the Central Control Commission, Ordzhonikidze acted as one of the main accusers.
ETHNICITY FACTORS IN THE TERRITORIAL PARTITION OF URAL REGION AND BASHKORTOSTAN REPUBLIC IN THE 1920s

Published: November 2022

The article analyzes the situation of border conflicts between the Ural region and the Bashkir Autonomous Socialist Republic (BASSR) over the territory of the bend of the Belaya and Kama rivers in the 1920s. It is emphasized that nowadays, there is a narrative in historiography about the predominance of “national republics” in the USSR in the 1920s, but this provision may be revised. Until 1918, the lands in question belonged to Bashkir landowners, but were inhabited by Russian peasants who took them on lease. After the Bolsheviks came to power and the abolition of lease relations, both the Ural region and the Republic of Bashkortostan claimed these territories. The former pointed to the Russian composition of the population, the latter indicated the established economic ties. The paper examines in detail the development of this conflict, the application of the existing mechanisms and tools of decision-making of that time, as well as the role of the ethnic component in them. After lengthy negotiations at the level of local authorities, no compromise was reached. The authorities of the Republic of Bashkortostan campaigned among the local population and engaged specially trained respondents for surveys, while representatives of the Ural region refused to accept any opinion that did not correspond to the idea of local peasants transferring with their land to the Ural region. As a result, the issue was considered by the Administrative Commission of the All-Russian Central Executive Committee, and the disputed territories were assigned to the Ural region. Therefore, in a state that has abandoned the prejudices of the past, the ethnic principle has played a key role in defining the boundaries of regions. This example shows that the Bolsheviks, even in the early years of Soviet power, were guided not only by the policy of unconditional preferential treatment of “national republics”.
AELFFLED, ABBESS OF WHITBY, IN ANGLO-SAXON HAGIOGRAPHIC TRADITION AT THE TURN OF THE 7TH AND 8TH CENTURIES
Authors:   Voronezh State Medical University named after N.N. Burdenko, Boldyreva I. I.
Published: November 2022

The paper focuses on the representation of Aelffled, abbess of Whitby, in hagiographical works of Anglo-Saxon church writers at the turn of the 7th and 8th centuries. The research is based on Stephen of Ripon’s live of Saint Wilfred of York and two lives of Saint Cuthbert, composed by an anonymous monk of Lindisfarn and Bede the Venerable. Within the first centuries after the Christianization of England, the authority of noble Anglo-Saxon abbesses was based on their kin relations with the ruling houses. A member of Northumbrian royal dynasty, Aelffled was one of the most powerful women in England of her time. She took interest in written culture, succession strategies, and church politics. Her circle of social contacts stretched far beyond the monastery walls. In the life of Saint Wilfred, Aelffled is shown as a prominent public figure. The hagiographic tradition devoted to Cuthbert of Lindisfarn reveals her emotional world, personal interaction with the wonderworker and her involvement in the affairs of Northumbrian royal house. Literary portraits of the second abbess of Whitby illustrate the high social position of noble ladies who were at the head of Anglo-Saxon double houses, as well as the dubious attitude of church milieu towards their political activities. Among other factors that determined Aelffled’s portrayal by her contemporaries were the circumstances of their works’ composition, individual biographic features of the saints to whom the vitae were devoted to, and the narrative’s micro-context. Based on the comparative and contextual analysis, the author attempts to revise the attitude expressed by modern gender historians about Bede’s hostility towards abbess Aelffled.
COVID-19, global health and climate change: Causes and convergences
Authors: Benatar Solomon R.
Published: November 2022

Despite massive global economic growth and advances in science and medicine with spectacular aggregate and individual improvements in health and life expectancy over the past century, the world has now become severely unstable in multiple domains – biological, sociological, political, ecological, economic, and health care. These pervasive instabilities are organically interactive within a complex world system that has reached crisis status at local, global, and planetary levels. Lying at the heart of this complex crisis are long-neglected disparities in health and well-being within and between countries, the refusal to face how these and climate change have arisen, and how economic considerations have fuelled the trend towards entropy (gradual decline of the planet into disorder). The critical point we have reached, starkly highlighted by the emergence of the COVID-19 pandemic pari passu with ongoing climate change and planetary degradation, reminds us of our global interconnectedness with each other and with nature. Comprehending and acknowledging the myriad, humanly constructed forces in each of these domains influencing all aspects of life, are the first steps towards effectively facing challenges to our health, our humanity (collectivity as humans) and our planet. Overcoming denial, acknowledging the magnitude and complexity of these challenges, prescient vision and dedicated action capable of fostering the cooperation for overcoming obstacles are now vital to seeking peaceful pathways towards more equitable and sustainable lives. South Africa is a microcosm of the world, with its local threats and challenges mirroring the global. Significance: Instabilities that pervade the world, highlighted by the COVID-19 pandemic, are especially significant for South Africa, where they manifest most starkly because of its apartheid legacy, its relative success economically on the African continent, and the implications of ongoing widening disparities and antagonism amongst South Africa’s diverse people. Belief in moving towards narrowing wide disparities through decolonisation and reversion to an ‘idyllic African heritage’ via a transformation that includes widespread corruption, and the ANC government’s perverse erosion of lives today and in the future through ‘state capture’, intensifies rather than ameliorates our predicament in an era when cooperation and a clear vision of current threats and future possibilities are desperately needed. In an accompanying article, potential pathways towards a better future are offered through suggested shifts in paradigms of thought and action.
Genus zero of projective symplectic groups

Published: November 2022

A transitive subgroup G ≤ SN is called a genus zero group if there exist non identity elements x1 , . . . , xr∈G satisfying G =, x1·...·xr=1 and ind x1+...+ind xr = 2N − 2. The Hurwitz space Hinr(G) is the space of genus zero coverings of the Riemann sphere P1 with r branch points and the monodromy group G.In this paper, we assume that G is a finite group with PSp(4, q) ≤ G ≤ Aut(PSp(4, q)) and G acts on the projective points of 3-dimensional projective geometry PG(3, q), q is a prime power. We show that G possesses no genus zero group if q > 5. Furthermore, we study the connectedness of the Hurwitz space Hinr(G) for a given group G and q ≤ 5.

Whole genome amplification of dengue virus type 1 - 4 v1
Authors: Nagy Anna
Published: November 2022

Dengue virus is one of the most often imported tropical viral infection in Hungary. For next-generation whole genome sequencing of dengue virus serotypes 1 - 4, a one-step reverse transcription PCR assay was developed. PCR amplicons can be used for further amplicon based sequencing protocols on Illumina MiSeq platform. The genome of the dengue virus is a single-stranded, positive-sense, capped RNA of approximately 10–11 kb in length. The whole genome amplification was carried out by five overlapping PCR amplicons, each one is approximately 2500 nucleotide in length. For ampification of the four serotypes, four different primer sets were designed by Geneious Prime (version 2021.2.2) primer design tool.
“Passive” Ecological Gentrification Triggered by the Covid-19 Pandemic
Authors: Broitman Dani
Published: November 2022

Urban areas can be conceptualized as large and ever-changing playgrounds in which many diverse agents (households, businesses, developers, municipalities, etc.) are active. The interactions between the playground qualities and the players’ preferences are not unidirectional. However, sometimes, external events may change the perception of the playground qualities in the player’s eyes. The recent Covid-19 pandemic and its associated precautionary measures are a clear example. During the pandemic, the value of existing urban green infrastructures has increased, as lockdowns were imposed, and distance working became widespread. The concept of “passive” ecological gentrification is developed in order to characterize this type of process. In contrast with “active” ecological gentrification, caused by purposeful intervention in the urban arena, “passive” ecological gentrification is triggered by a change of context, such as the pandemic impacts. This article focuses on the appreciation of green urban infrastructures by urbanites during the pandemic, showing that the willingness to pay to live near green and open spaces has increased in general, but with significant spatial differences. The main research questions are: (a) How does the player’s perception of the playground’s value change in times of pandemic? (b) Do these changes support the emergence of “passive” ecological gentrification? The methodology is based on the analysis of changes in property values over time as an indirect measure of a location’s appeal, looking specifically at areas near green urban infrastructures, both in the inner city and in the peripheral areas. Relatively large changes in property value over time are a possible indicator of ongoing gentrification processes: When they are observed near existing green infrastructures, and not related to redevelopment initiatives, “passive” ecological gentrification may be the result. Using detailed spatial data on land use and property prices from the Netherlands, we find evidence that supports the hypothesis of a “passive” ecological gentrification drift towards areas around urban parks and green infrastructures in general.

Published: November 2022

The application of the method of boundary integral equations is considered for studying the stress state of flat viscoelastic bodies with inclusions. The method is based on the use of complex potentials and the apparatus of generalized functions. An analytical solution of the problem is obtained for a half-plane with inclusions of arbitrary shape. For a numerical study of the change in the stress state depending on the time and geometry of the inclusions, a discrete analogue of the system of boundary-time integral equations has been developed.

Optoacoustic imaging is based on the generation of thermoelastic waves by heating an object in an optically inhomogeneous medium with a short laser pulse. The generated ultrasonic waves contain information about the distribution of structures with predominant optical absorption. Detection of acoustic perturbations on the surface of the object and the application of the backprojection algorithm are used to create a picture of the absorbed energy inside the environment. Conventional reconstruction methods lead to artifacts due to the peculiarities of the recovery algorithm. This study proposes an iterative procedure to reduce these artifacts. The algorithm minimizes the error between the measured signals and the signals calculated from the recovered image. The paper compares the results of processing optoacoustic signals implemented in numerical experiments with the results of physical experiments. It is shown that the quality of the recovered images improves even with a small number of iterations.

The importance of electrocardiogram (ECG) analysis is difficult to overestimate. Rhythm of life, stress and other factors affect the frequency of diseases and their early appearance. At the same time, the technologization (digitalization) of life and hardware-software complexes, such as mobile electronic cardiographs and wearable devices in general, which are rapidly developing, open new opportunities for rapid analysis of human state by certain indicators, as well as allow to diagnose on the new higher level in almost real time. There are many methods for analyzing cardiograms. In this paper, the authors propose a new approach based on an ensemble of individual classifiers, which effectively solves the problem of ECG analysis. The study is based on the PhysioNet Computing in Cardiology Challenge 2017 and the MIT-BIH Arrhythmia Database. The algorithm consists of the following stages: data filtering using moving average and Butterworth filters, R-peak localization via threshold and grouping method, ECG resampling for the better comparability, “Noisy” vs “NotNoisy” classification as the most hard-to-identify class, final classification as “Normal”, “Atrial Fibrillation”, “Other” using an ensemble of 1D CNN classifiers and a final classifier of selection using logistic regression, random forest or support vector machine (SVM). The proposed method shows high accuracy by the metric F1, so it gives the background for further research, optimization and implementation. This way this algorithm could help to save human’s life by in-time detection of problems with cardiovascular system (CVS) at early stage.
Design and Modeling of Stock Market Forecasting Using Hybrid Optimization Techniques
Authors: Trivedi Hemendra Kumar , Saxena Abhigya
Published: November 2022

In this paper, an artificial neural network-based stock market prediction model was developed. Today, a lot of individuals are making predictions about the direction of the bond, currency, equity, and stock markets. Forecasting fluctuations in stock market values is quite difficult for businesspeople and industries. Forecasting future value changes on the stock markets is exceedingly difficult since there are so many different economic, political, and psychological factors at play. Stock market forecasting is also a difficult endeavour since it depends on so many various known and unknown variables. There are several ways used to try to anticipate the share price, including technical analysis, fundamental analysis, time series analysis, and statistical analysis; however, none of these approaches has been shown to be a consistently reliable prediction tool.
We built three alternative Adaptive Neuro-Fuzzy Inference System (ANFIS) models to compare the outcomes. The average of the tuned models is used to create an ensemble model. Although comparable applications have been attempted in the literature, the data set is extremely difficult to work with because it only contains sharp peaks and falls with no seasonality. In this study, fuzzy c-means clustering, subtractive clustering, and grid partitioning are all used. The experiments we ran were designed to assess the effectiveness of various construction techniques used to our ANFIS models. When evaluating the outcomes, the metrics of R-squared and mean standard error are mostly taken into consideration. In the experiments, R-squared values of over.90 are attained.
Russian Parliamentarism as a Social and Legal Phenomenon
Authors: Zubarev A. S.
Published: November 2022

The paper discusses theoretical approaches to understanding Russian parliamentarism. The author analyzes generic and specific features, examines variants of the doctrinal interpretation of parliamentarism. There are two main approaches that reveal the concept of «parliamentarism». First, there is an approach that considers parliamentarism within the framework of the category «a form of the State» and its structural elements. The second approach understands parliamentarism as a complex social phenomenon functioning within the framework of constitutional laws. In the Russian constitutional law doctrine, the institutional approach to defining the concept of parliamentarism is usually «incomplete», limited only to the consideration of individual elements (public relations or legal regulation). The article proves that the institutional approach makes it possible to present parliamentarism as a socio-legal institution that includes the following mandatory elements: values (goals), statutory regulation, institutional subject composition and relevant social relations.

BACKGROUND: There has been an increase in the prevalence of autism spectrum disorders (ASD) worldwide over the past decades. Studies have shown that the number of confirmed diagnoses correlates with the awareness of the disorder among the general public and the professional community, in particular, as well as the availability of formalized screening procedures and modern medical and educational tools for families raising children with ASD in regional population centers. Thus, comparing autism prevalence rates in regions of the same country helps identify regions with limited access to diagnostic services and adequate medical care.
AIM: To estimate the overall number of individuals meeting the diagnostic criteria for ASD in Russia and determine the differences in the number of registered individuals with established diagnosis in the constituent territories of the Russian Federation.
METHODS: We conducted a retrospective, observational study and analyzed data from official statistical reports (form 12 Information on the Number of Diseases Registered in Patients Residing in the Service Area of a Healthcare Institution for 20202021).
RESULTS: A steady upward trend in the number of individuals with autism has been observed since 2014 in the Russian Federation as a whole and in the federal districts, although the prevalence rates differ from the global median prevalence of ASD (all-Russian figure by almost 40 times). In addition, regional differences (by 104.5 times) in the frequency of the diagnosis have been revealed: from a minimum of 1.7 to a maximum of 177.7 per 100,000 population. The percentile distribution of the number of individuals with ASD that are followed-up at healthcare facilities in the constituent territories of the Russian Federation was in the interquartile range (2575th percentile), below the 25th percentile, and above the 75th percentile in 38, 26 and 21 regions, respectively.
CONCLUSION: The study has shown significant differences in the ASD diagnosis rates by regions in the country against a backdrop of a low (compared to international data) number of registered cases of autism. The presented data suggest that, due to the lack of proper diagnosis, a significant number of individuals with ASD do not receive adequate medical care, nor do they receive social, psychological, or pedagogical support. Possible reasons for this probably include low awareness of new diagnostic approaches among psychiatrists; low level of involvement of pediatrics professionals in screening activities; and fear of stigmatization because of a psychiatric diagnosis in the absence of a developed medical care infrastructure that encompasses a social, psychological, and pedagogical support system for people with ASD.

BACKGROUND: The number of poisoning with a muscle relaxant baclofen has increased recently. The brain is one of the target organs in baclofen poisoning.
AIM: To identify and quantify cerebral cortex neuron damage in baclofen and baclofen ethanol poisoning.
MATERIAL AND METHODS: A histological study of rat cerebral cortex was performed. The controls (n = 5) received neither baclofen nor ethanol. Groups 1 and 3 received baclofen (85 mg/kg), whereas groups 2 and 4 received baclofen (85 mg/kg) and ethanol (7 ml/kg). Groups 1 and 3 were euthanized 4 h after the drug administration, whereas groups 2 and 4 were euthanized after 24 h. Histological sections were stained with hematoxylin and eosin and by the Nissl method and examined by light microscopy (400). The number of damaged neurons was calculated. Statistical processing was performed by the nonparametric MannWhitney method.
RESULTS: Neurons with reversible and irreversible changes in the controls accounted for 13% and 9%, respectively. At 4 h after baclofen administration, neurons with reversible and irreversible changes accounted for 22% and 21%; 4 h after baclofen and ethanol administration, 24% and 29%; 24 h after baclofen administration, 25% and 37%, respectively. Baclofen and ethanol administration caused an increase in the share of neurons with reversible (27%) and irreversible (41%) changes. The differences between group 3 and the control group were significant, and the difference was significant when group 4 was compared with the control group and group 3.
CONCLUSION: Understanding the processes in the brain during baclofen and baclofen ethanol administration will allow the provision of medical care to this category of patients more effectively. The signs of brain neuron damage, along with the results of forensic chemical analysis, can be used to establish the immediate cause of death.
Determination of human sex by odontometric characteristics using equations of logistic regression

BACKGROUND: The development of methods for identifying a person based on bone remains, which are adapted for diagnosing the population of Azerbaijan, is a priority in view of the incompleteness of solving this problem. In this situation, a new way to quickly determine the sex by teeth appears to be in demand because it should increase the efficiency of the work of forensic doctors.
AIM: To develop a modern technique for diagnosing a persons sex using odontometric signs.
MATERIALS AND METHODS: Teeth sizes were studied at the craniological collection of Azerbaijanis. On the seven teeth of the upper and seven teeth of the lower jaw, three parameters were measured (while symmetrical teeth were considered a single array). Each of the 14 anatomical teeth was represented by 80 male and 80 female teeth. A digital caliper (Mutitouyo; accuracy 10 microns) was used for odontometric procedures. Odontometry results were analyzed by statistical methods using receiver operating characteristics curve analysis. Mathematical modeling was conducted using the MATLAB statistical software package.
RESULTS: With the help of the receiver operating characteristic curve (ROC) analysis, the data obtained in the course of odontometry were studied. Six odontometric signs were related to sex. The most sex-related parameters were the buccolingual diameter of the upper canine, heights of the crowns of the second lower molar, lower incisors, lower canine, and upper central incisor. Using mathematical modeling, six logistic regression equations have been implemented, which help determining the sex of an individual by the size of his teeth possible. The predictive potential of the equations was also assessed using the ROC analysis.
CONCLUSION: Based on odontometric indicators and ROC analysis, diagnostic equations for determining the sex of a person by the teeth size were obtained. The equations have not yet been verified on independent samples; therefore, they cannot yet be unconditionally recommended for practice. Nevertheless, the authors count on the high legitimacy of their models because they used a fairly powerful mathematical apparatus.
Dynamics of mortality of the population of the Krasnoyarsk Territory from preventable and treatable causes

INTRODUCTION: In the context of the development of measures aimed at reducing the mortality of the population, it is BACKGROUND: In developing measures to reduce mortality in the population, it is important not to directly analyze the mortality of the population but to study its manageable components attributed to preventable and treatable deaths.
AIM: To analyze trends in mortality due to preventable and treatable causes in the population of the Krasnoyarsk Territory.
MATERIALS AND METHODS: A retrospective observational study was done using data from primary mortality databases of urban districts and municipal districts of the Krasnoyarsk Territory for the period 19992020, as well as data from the Office of the Federal State Statistics Service for the Krasnoyarsk Territory, the Republic of Khakassia and the Republic of Tyva on the population. The study examines how f preventable and curable causes contribute to the mortality structure of the population of the Krasnoyarsk Territory for the period 19992020.
RESULTS: Over the period 19992019, the mortality rate of the population decreased by 13.4% (from 1413.2 to 1224.2 cases per 100,000 people), but in 2020 mortality rate increased by 16.7%, becoming slightly higher than its 1999 level. Analysis of the structure of mortality from leading causes of mortality showed a systematic increase in the proportion of unavoidable and incurable causes from 1999 to 2020.
CONCLUSION: The results of this study can serve as a guideline for determining the reserves for reducing the mortality of the population and for determining promising directions for reducing it at the regional level. However, to achieve this, a more detailed analysis of the mortality structure of the population is required in order to identify groups of headings, headings or individual causes of death, for which there is a high proportion of preventable and curable mortality.
