A spatial analysis of intra-regional transport accessibility of settlements in the Arctic districts of the Sakha Republic (Yakutia) by GIS is an urgent task and can become a necessary support for the processes of decision-making and planning of sustainable development of these territories. The purpose of the study is to perform a spatial analysis of intra- regional transport accessibility of settlements in remote Arctic regions of Yakutia on the example of Anabarsky and Nizhnekolymsky districts. On the basis of the GIS network analysis and calculated coe cients of density of the transport network, the assessment of transport accessibility of the study areas according to winter and summer scenarios was carried out. The automobile and river networks were built on the basis of data from open cartographic sources: OpenStreetMaps and Google Earth Engine, the atlas of highways of the Sakha Republic (Yakutia). On the basis of satellite images of Landsat 5, 8 and Sentinel 2, non- o cial (informal) roads that play an important role in communications between settlements were decrypted and digitized. QGIS and ArcGIS programs were used to perform network analysis and build a map of time availability of the settlements using isochronous method. The created maps clearly show the availability of settlements by time interval. The conducted research made it possible to determine that remote sensing and geoinformation systems are key tools for a spatial analysis of transport infrastructure. Using this tools, it is possible to conduct network analysis of various levels of complexity, as well as build graphs of the transport network, greatly simplifying the counting procedure. The paper tested a method that allows to identify uno cial roads in the Arctic, and the presented methods of GIS analysis and modeling that can be used for further deeper network analytics and graph theory to improve the methodology for studying the transport accessibility of the Republic of Sakha (Yakutia).

Changes in metabolism at high latitudes are a physiological adaptation to “northern stress” caused by the influence of meteorological and heliogeophysical factors. The study of metabolic blood parameters can serve to assess the risk of developing the disease in the future due to a decrease in the body’s adaptive reserves when it is influenced by environmental factors of various nature. The stress potential of natural northern climatic and geophysical factors may increase in relation to those people who come to the North from regions with a temperate climate and work in specific conditions, in particular in water transport.The water transport workers of Yakutia in the number of 206 men were examined, with 96 of them coming from other regions of the Russian Federation. The biochemical parameters of blood serum were evaluated according to groups formed according to the level of adaptive potential (AP). Anthropometric (height, weight) and functional (heart rate (HR), systolic and diastolic blood pressure (SAD, DAD)) were determined body parameters, as well as biochemical parameters of blood serum. The level of AP, the de Ritis coefficient (CDR) and the atherogenicity coefficient (CA) were calculated. The results obtained made it possible to identify violations of adaptation processes among employees, mainly among newcomers. According to biochemical parameters, deviations in the level of enzymes, glucose, de Ritis coefficient (CDR) and atherogenicity coefficient (CA) were revealed.

The article describes a case of the development of a severe form of bronchopulmonary dysplasia in a premature newborn. Globally, about 15 million children are born prematurely every year. On average, it is every tenth child. In Russia, more than 110 thousand children are born prematurely every year, which is about 5.7 % of all newborns per year. [8] This confirms the relevance of the chosen topic. The ABS test falls under the category of express studies, since its parameters change rapidly with any shifts in the patient’s condition (respiratory indicators, body temperature, physical activity, kidney function, etc.). [9] The study of blood pH revealed subcompensated metabolic acidosis, confirming the literature data. The gas composition of the blood varied from hypocapnia to hypercapnia, which indicated a severe degree of respiratory failure with a picture of hypoventilation of the lungs in premature newborns. The revealed decrease in electrolytes was associated with diuretic and steroid therapy used for the patients with bronchopulmonary dysplasia. Due to prematurity, compensatory mechanisms were insufficient to maintain homeostatic parameters (pH, gas and electrolyte composition of blood). When conducting oxygen therapy with a ventilator, it is necessary to be guided by the dynamics of ABS tests to calibrate the parameters of the device and adjust infusion therapy.

Nowadays, dental anomalies in children and teenagers are common pathologies that have a negative impact on the functional state of the organs and tissues of the oral cavity, as well as in general physical development. At the same time, they have a wide range of etiological factors and pathogenetic mechanisms of their development. According to the literature, the problems of occlusion disorders in congenital collagenopathies have not been sufficiently studied, which gave a reason to choose the direction of this research work. Aim. To study the parameters of anatomical deformities of the alveolar process of the upper jaw in deep bite in children and teenagers with various degrees of severity of connective tissue dysplasia. Materials and methods. A study of 306 children and teenagers with DST aged 12-18 years was conducted, of which 157 boys and 149 girls. Deep bite was diagnosed in 124 schoolchildren. The degree of DST was determined by the method of T. Milkovska-Dmitrova and A. Karkashev (1985). At the medical appointment, after determining the dental status, there was performed a biometric study on plaster models of the patient. To obtain objective data, there was used the standard Pon and Tone method. Results. Of all the examined groups of children and adolescents with DST, 37.92+1.08 % with deep bite were diagnosed, where the indicator of mild DST was at the level of 41.94+1.01 %, and moderate and severe 30.64+1.21 % and 27.42+1.26 %, respectively. The dynamics of the average statistical data of the premolar index shows an increasing trend for the severity of anatomical deformities of the alveolar process of the upper jaw in the form of narrowing. The dynamics of the molar index at various degrees of severity of DST determines that with a mild degree, narrowing was observed, whereas with an average degree, pronounced expansion of the alveolar process of the upper jaw was diagnosed, where this value decreases to a severe degree. Conclusions. The established parameters of the values of anatomical deformities of the alveolar process of the upper jaw in deep bite, depending on the severity of DST in children and adolescents, contribute to timely diagnosis and prompt implementation of therapeutic and preventive measures, which accordingly eliminates or minimizes long-term complications of local phenotypic manifestations of congenital collagenopathy.

Smoking and vaping are common bad habits, especially among young people. Studying this phenomenon among students is important for developing programs to prevent smoking initiation and help in quitting it. These programs can help improve youth health and reduce the risk of serious illnesses. Purpose: to study the prevalence of smoking traditional cigarettes and electronic cigarettes (including vaping) among 1st-year students of the Ammosov North-Eastern Federal University. The study covered 152 1st-year students of one of the educational departments of the North-Eastern Federal University aged 17 to 30 years (average age 20.62±2.97). A data analysis was performed using the IBM SPSS Statistics software package. A comparison of two groups according to a quantitative indicator with a normal distribution, provided that variances were equal, was performed using Student’s t-test. The share of non-smoking respondents slightly prevailed - 61.8 % (94). The proportion of smokers was 39.2 % (58), of which 35 women (60.34 %), 23 men (39.65 %), the average age of women and men was 20.6 ± 3.03 and 20.65 years, respectively. The smoking experience in men was significantly higher: the average smoking experience in men was 6.48±5.18 years, in women -3.17±2.53 (p=0.002). Thus, men started smoking on average at 14.17±3.96 years, women - at 17.43±3.62 (p=0.002). The smoking index ranged from values close to zero to 7.2 pack/years (mean value - 1.23±1.62 pack/years). The results showed that the majority of respondents noted an increased desire to smoke in a state of stress - 40 (69 %), shortness of breath - 30 (51.7 %), skin problems - 26 (44.8 %), fatigue - 25 (43.1 %), gastrointestinal disorders - 16 (27.6 %), “lump” in the throat - 15 (25.9 %), cough - 22 (37.9 %), frequent headaches 20 (34.5 %), blurred vision - 14 (24.1 %), and attacks of suffocation - 5 (8.6 %). None of the symptoms were noticed in 6 out of 58 (10 %) respondents. The majority of students who combine smoking with vaping do not plan to give up the bad habit (73.07 %), students smoking traditional cigarettes also showed a high percentage of adherence to the bad habit, with 50 % not planning to give up smoking. Thus, this study highlights the need to develop programs to prevent smoking initiation and help to quit among students, which can help improve the health of young people and reduce the risk of serious diseases.

This article reflects research and analysis of physical activity classes for maintaining a healthy lifestyle in rural areas at the place of residence. The goal is to study the physical activity of the population at their place of residence in rural areas. The hypothesis of the study is the assumption that if the organization of physical culture and mass leisure at the place of residence is qualitatively improved, taking into account the opinions of the villagers, then physical activity and maintaining a healthy lifestyle will improve. The methods used were analysis of scientific literature, observations, conversations, questionnaires, and the results obtained were processed by the method of mathematical statistics. Together with the residents and the village leadership, they organized recreational activities for the villagers throughout the year. As a result, the percentage of participants engaged in physical activity increased. As a result of the work carried out, the percentage of residents attracted has improved. If in 2021 the population coverage was 16.9 %, then in 2022 it became 22.6 %, which is 5.7 % higher. In 2024, the goal is to increase the number of people involved in sports and physical education in the village to 50 %. If they work this way, then this goal is achievable.
