Towards an Integrated Approach to Recording Military Aircraft Crash Sites
Authors: Masters Peter , Osgood Richard
Published: July 2021

The forensic investigation of military aircraft crash sites has become in recent times part of mainstream traditional archaeology. Mostly amateur aircraft enthusiasts have undertaken the recovery of military aircraft crash sites without methodically recording the remains. The sites covered in this paper have been approached based on recording the in-situ remains methodically using traditional and scientific methods used in the field of archaeology from fieldwalking, metal detecting and geophysics. The strategy and methodology used in this investigation showed how effective and important it is to recover as much of the remains as possible to place it into a meaningful context in order to understand the reasoning for why these aircraft came to a devasting end by crashing into the ground at great speed. The excavations have involved Operation Nightingale—an MOD based recovery programme that specializes in archaeology. This paper will demonstrate the importance of using such an integrated approach to the recovery of military aircraft crash sites from the Second World War by referring to specific case studies.

Published: July 2021

In the context of the search of detainee disappeared from the dictatorship occurred in Uruguay, forensic archaeology uses GIS as an auxiliary tool which allows to create, edit, visualize, store, analyse and publish geospatial data and information related to the investigation process. The tools of GIS are described in this article to show the results and information obtained which are going to be useful in the analytic processes leading to the design of new search strategies and archaeological intervention according to the available resources for this context. Two case studies are presented with the purpose to show the use of QGIS as a result of the three main areas of work: preliminary, fieldwork and laboratory. QGIS is presented as one of the most versatile, dynamic and accessible tool to investigate the search of detainee disappeared in Uruguay.
The deformation model of the DCB-sample with elastoplastic properties
Authors: Glagolev V. V , Markin A. A
Published: July 2021

The loading of a strip with a crack-like defect according to mode I is considered. In contrast to the classical representation of a crack in the form of a mathematical section, the proposed model defines a crack as a physical cut with a characteristic linear size. The mental continuation of a physical cut in a solid forms an interaction layer (IL). It is important that the stress-strain state of the layer at a finite value of the linear parameter does not introduce a singularity into the crack model. The process of elastoplastic deformation with a constant layer length is considered. We obtained a simplified analytical solution to the problem of deformation of two elastic bodies connected by a thin layer with elastoplastic properties. The dependence of the displacement and stress fields on the length and thickness of the interaction layer has been found. It is shown that, under the classical plasticity condition, the range of variation of the external load leading to a purely elastic behavior is possible only for a finite layer thickness. As the layer thickness tends to zero, as in the Dugdale model, the plasticity region is formed at an arbitrarily small external load. For small layer thicknesses, a local plasticity criterion is proposed, by using which it is possible to distinguish the intervals of the external load variations associated with elastic and plastic deformations. The local plasticity condition, determined by the critical value of the energy product, makes it possible to reflect the stage of elastic deformation at an arbitrarily small finite thickness of the interaction layer. An asymptotic dependence of the external load on the IL thickness and the reduced length of the plastic zone is obtained. At the same time, the separation of the external load into elastic and plastic components is preserved. From the analysis of the experimental data, an estimate of the elastic limit of the energy product for the AV138 adhesive was obtained.
A Comparison of Experimental and Computation Results of Finding Effective Characteristics of Elastic Properties of Polymer Layered Composites from Carbon and Glass Fabrics
Authors: Muyzemnek A. Yu , Ivanova T. N , Kartashova E. D
Published: July 2021

Anisotropy of mechanical properties of the entire material and each of its layers is characteristic for polymer layered composite materials, as well as the fact that production processes of the composite material and parts from it are often combined in time. In this case, the elastic properties and strength of the material will be different not only in the thickness of the part, but also at each point. All this leads to a complication of the design process, which is due to the need to determine the elastic properties and strength of the polymer layered composite materials, taking into account the structure of the entire material and each of its layers. This work aims at evaluating the existing computational methods of finding effective characteristics of elastic properties by comparing computation results obtained by various methods with each other, as well as with the experimental results related to elastic properties of polymer layered composite materials from carbon and glass fabrics. We estimated the computational methods of finding effective characteristics of the elastic properties of composites based on the experimental results of finding the characteristics of the elastic properties of polymer layered composite materials made of carbon and glass fabrics, differing in density and type of weaving. The experimental values of the effective characteristics of elastic properties were determined as a result of standard tensile tests of laboratory specimens. As a result of the study, it was found that all the considered models and methods give consistent results when calculating the longitudinal modulus of elasticity E 11, the results of calculating shear modulus E 33 and shear moduli G 12 and G 23 are less consistent for all the considered materials. The comparison of the results of the experimental studies and computations showed that the Chamis model and the bridge model are better than other models to predict the values of the longitudinal elastic modulus.
Tradition as a Homeland to Return to: Transnational Religious Identity of the Post-Soviet Orthodox Jewry
Authors: Ostrovskaya Elena A.
Published: July 2021

This article highlights the outcome of a long-term field research into the transnational identity of the post-Soviet Orthodox Jewry. It analyzes biographical interviews taken between 2015 and 2018 in St. Petersburg and Minsk to define the religious identity and day-to-day practices of post-Soviet Orthodox Jews. In this article, I argue that the modern post-Soviet Jewry is a new socio-cultural phenomenon with no historical prototypes. As to the research methodology, it was a combination of the transnational approach, random choice case-study targeting post-Soviet Orthodox communities of Orthodox Jewry in large cities, and the biographical method. The backbone of the post-Soviet Orthodox communities of different strains of Judaism was formed in 1990–2008. It is made up of three generations of men and women born in the late 1940s–1960s, mid-1960s–early 1970s, and the 1980s. Each of these generations is characterized by its own unique pattern of observance, the formation of which is directly conditioned by the circumstances of involvement in religious Jewry. The transnational pattern of observance of the Post-Soviet Orthodox Jews involves the model they confronted at the very beginning of their journey, the model they learned in overseas educational institutions or through incoming envoys and rabbis in the country of residence, and the model of balance between the required and possible in the modern post-Christian and post-atheist environment.

Estado de la lexicografía de aprendizaje del latín en España: necesidad de nuevos modelos lexicográficos didácticos
Authors: Cruz Manuel Márquez
Published: July 2021

Durante los últimos setenta años, la lexicografía española de aprendizaje del latín ha producido diccionarios cuyo uso se ha destinado principalmente a resolver cuestiones planteadas por los estudiantes en relación a la traducción de textos latinos. Recientes estudios han demostrado la necesidad de hacer más atrayentes y efectivas las metodologías de aprendizaje del latín, una mejora a la que podría contribuir la confección de nuevos diccionarios de aprendizaje del latín con un enfoque exclusivamente didáctico. Este trabajo supone un estudio crítico que evidencia las carencias didácticas de los denominados diccionarios didácticos de latín, tomando como ejemplo el tratamiento de un artículo lexicográfico verbal en los diccionarios analizados y aportando una propuesta teórica y práctica de un modelo de diccionario didáctico, alternativa a los diccionarios bilingües utilizados en las aulas. Concluye con la necesidad de confeccionar diccionarios didácticos de latín que proporcionen conocimiento sistemático del funcionamiento de la lengua latina.
The forgotten agenda of Brazilian federalism: asymmetry, heterogeneity and diversity of Prosecution Service
Authors: Abrucio Fernando Luiz , Viegas Rafael Rodrigues , Rodrigues Rayane Vieira
Published: July 2021

This paper examines the forgotten agenda of the justice system studies in Brazil: the association between federalism and the Public Prosecution Service (MP). The public administration and political science studies still provide a homogeneous overview of MP, neither considering the political and organizational asymmetry between the federal and state institutions, nor the heterogeneities and diversities existing in the Brazilian state structures. While the analyzes of the Executive and Legislative branches included the federative dimension as a key variable, the justice system studies do not consider federalism in their investigations, especially in the MP studies. Beyond pointing this conceptual fragility, the main contribution of this work is the creation of a theoretical framework to be tested in future empirical research about the MP, composed of the following elements: relationship with the local elite, the construction of the corporation's professionality in each local reality and the predominant options for controlling Public Administration and public policies at the subnational level throughout the Federation.
Understanding the Intention of Sex Tourism Using Extended Theory of Planned Behavior : A focus on the Roles of Perception and Prior Knowledge of Prostitution
Authors:   The Tourism Sciences Society Of Korea, Gu Hye-Min , Jeong Ji-Youn
Published: July 2021

Using the extended theory of planned behavior, this study was to analyze the effects of ethical and social perceptions, human rights perceptions, and health perceptions related to prostitution, as prerequisite variables on the attitudes and behavioral intentions of sex tourism. Structural equation model analysis and ANCOVA were performed to test hypotheses using a total of 304 valid questionnaire responses. Results showed that ethical and social perceptions and health perceptions had a significant negative effect on attitudes toward sex tourism, whereas human rights perceptions did not. It was also found that attitude and subjective norm had a significant positive effect on behavioral intentions, but perceived behavioral control did not significantly affect sex tourism intentions. In particular, it appeared that the ethical and social perception had a significant total negative effect on the intention of sex tourism. In the moderating effect analysis, using prior knowledge of prostitution-related laws, the group with high prior knowledge level had a relatively lower influence on behavior of sex tourism attitudes than the group with low level of prior knowledge. However, ANCOVA found no significant differences between the two groups, indicating that moderating effects differ by gender. This study has academic value in that it conducts an empirical study on sex tourism, a topic that is somewhat difficult to bring out in Korea. Results of this study could contribute to establishing effective policies to reduce illegal sex tourism.
An analysis of the Actual State and Structure of the Regional Tourism Establishment Plans through the Exploratory Data Analysis(EDA) Technique: Applying the Open API of the Korea On-Line E-Procurement System(2014~2018) of the Public Procurement Service
Authors:   The Tourism Sciences Society Of Korea, Lee Yoon-Goo , Park Gyung-Yeol
Published: July 2021

Using the method of exploratory data analysis and text mining analysis, this study analyzed the regional tourism plan research project structure of South Korea from 2014 to 2018 in terms of research grant amount, research types and funding institutions. It also explored the relationships among regional tourism research topics through a semantic approach. In order to achieve the goals of the study, ‘Actual State of Tourism Development Plans’, which were established by ‘Central and Local Governments and Policy Task’, were used for the data analyses. Results showed that the budget of each regional tourism planning projects was not proportional to the annual growth rate of the number of local tourism planning projects. It was also found that local governments were the major funding agencies for the regional tourism development plan projects. Only a few of the research projects were funded by business sectors or local communities. Results also showed that Gangwon province conducted the most number of regional tourism planning projects, while Jeollanam province used the most amount of research money for the regional tourism planning. In terms of the research topic numbers, basic regional tourism master planning were the most and it was followed by the master plan changes. Results of this study could be used for an appropriate decision making for the regional tourism planning research directions and the amount of research grant in the future.

With over a year after the first coronavirus case reached Delhi, the total number of infections anddeaths has reached a sky-high mark. The response of the Delhi government involved the impositionof multiple lockdowns. This decision, though slowed down the positivity rate, had unprecedentedeffects on the dietary habits of young individuals in the city. Forced to stay at home due to thelockdown, these individuals engaged in unhealthy daily routines and dietary habits. With the closelink between diet and immunity it becomes imperative to collect data in this regard. The presentpaper records the dietary habits of individuals in the city using a web-based survey. The findings arepresented and analyzed graphically. It was observed that the lockdown harmed the dietary habits ofyoung individuals. A decrease in the level of exercise, water intake and increase in weight were themajor variables leading to this conclusion.

Appropriate child feeding practices in the initial six months of age act as a preventiveintervention against childhood morbidity and mortality. Methods: A questionnaire-based cross-sectional study was conducted in an urban slum to study various feeding practices prevalent amongchildren up to 6 months of age. Also associated socio-demographic factors were studied. SPSSsoftware version 25 was used to analyze the results. Results: The study included 55 children up to6 months of age. Out of these 76.4% were exclusively breastfed. Among 45.5%, breastfeeding waswithin 1st hour of the birth. 56.4% have received pre-lacteal feeds, while 72.72% receivedcolostrum. The educational status of the mother and place of delivery were major determinants ofappropriate infant feeding practices. Conclusion: Most mothers are practising exclusivebreastfeeding. Colostrum was fed to most of the children. Animal milk was given in cases whereinitiation of breastfeeding was delayed.
Acuñación, difusión y usos del término «literatura de cordel» en español
Authors: Lora Márquez Claudia
Published: July 2021

La presencia documental del término «literatura de cordel» en español se constata al menos desde la segunda mitad del XIX, si bien la fama incontestable del Ensayo sobre la literatura de cordel de Julio Caro Baroja (1969) ha hecho que en determinados ambientes se instale la creencia de que fue su autor quien lo puso en circulación por primera vez. El presente artículo busca dilucidar la etimología de la expresión atendiendo a fuentes hemerográficas y literarias, lo que en última instancia permite postular su origen luso así como su vinculación con el folklorista azoriano Teófilo Braga.

Authors: Shtokvysh O. , Koval L. , Dyakonenko V. , Pekhnyo V.
Published: July 2021

Binuclear complex of Zn(II) with cyclohexyl acetoacetate was obtained and structurally characterized for the first time. According to structural data, the crystal system is triclinic, space group P-1; a = 7.6530(4), b = 12.2412(8), c = 12.9102(9) Å; α = 90.198(5), β = 101.071(5), γ = 96.937(5) deg. The molecular structure corresponds to the formula [Zn2(C10H15O3)4(C2H5OH)2]. The complex is located in a special position to the symmetry center of the unit cell. The coordination polyhedrons of the Zn atoms are the same distorted octahedrons formed by six oxygen atoms. Each formed by 4 oxygen atoms in the equatorial position, which belong to three ligand molecules: terminal ligand (2 oxygen atoms) and bridged ligand (1 oxygen atom) which chelate the zinc atom of the named polyhedron and 1 oxygen atom belong to a bridged ligand that chelates the other nucleus and monodentantly coordinated to mentioned one. Two oxygen atoms occupy an axial position, one of which belongs to the terminal ligand, mentioned above and the other to the coordinated ethanol molecule. The bond between the complex nuclei is stabilized by two hydrogen bonds formed by the hydrogen atoms from hydroxyl groups of ethanol molecules and the enol oxygen atoms of the terminal ligands of the other nucleus. The compound was also characterized by IR-spectroscopy, characteristic bands (сm-1) are: ν(C–H) - 2936, 2860, ν(C=O) & ν(C=C) – 1612, ν(C=O) + δ(C–H) – 1532, ν(C=C) & ν(C-CH3)– 1252, δ(C–H) – 1172, π(C–H) – 784, ν(M–O) – 456, 416. IR spectroscopy data confirm the bidentate coordination of cyclohexyl acetoacetate to zinc atoms in deprotonated form with the formation of chelated metallocycles. The structure of the complex is similar to the structures of cobalt and nickel complexes with cyclohexyl acetoacetate. Analysis of XRD-data (which are supplemented with this work) for Co(II), Ni(II) and Zn(II) complexes with acetoacetic acid esters shows that their structure, in particular the number of metal centers in the structures, regardless of the nature of the central atom or the alcohol fragment, but determined the presence of components capable of complementing the coordination sphere of the metal in reaction media.

Authors: Zherdev I.Y. , Barabanschikov V.A.
Published: July 2021

Extreme temporal condition for visual identification task is held. A gaze-contingent eyetracking study was used to assess how presaccadic stimulus influences the one presented during a reactive saccade. A strong forward masking effect is found. Identification rate of second image is below chance, but still in accordance with previous studies, where no masking was present. Identification rate, erratic responses, statistical connection with alternative response (2AFC task), physical properties of saccades are similar to simple intrasaccadic identification task [3; 5]. Two aspects of transsaccadic visual perception were hypothesized, possessing common temporal structure: sensoric (geometric primitive detection) and gnostical (naturalistically valid object identification).

Published: July 2021

The aim of the present experimental study was to investigate possible associations between indi - vidual cooperativeness and facial morphology. Participants of the study were Buryats of Southern Si - beria (males: N=98; females: N=89; mean age 20 ± 2y.). Individual cooperativeness was assessed in experimental economic game “Public Goods Game”, which was conducted “face-to-face”, in groups of 4 same-sex individuals, who were strangers to each other. The game involved real monetary pay-offs. In the course of the experiment such individual behavioral features as propensity for unconditional/conditional cooperation, selfishness, or free-riding were revealed. Facial shapes of participants were explored through anthropological photographs using geometric morphometrics, and via assessing standard facial indexes. As a result the relationship between facial shape and unconditional cooperation was identified and visualized. This relationship appeared only among males. The analysis of sex-specific facial traits of Buryats revealed that faces of male unconditional cooperators combined both male-specific, and female-specific facial features. This is the first study to investigate association between full facial shape and human cooperativeness.
Dynamics of Key Facial Points as an Indicator of the Credibility of Reported Information
Authors: Barabanschikov V.A. , Zhegallo A.V.
Published: July 2021

This research describes a method for studying the authenticity/unauthenticity of the information re- ported by people in video images. It is based on automatic tracking of coordinates of key points of a speaker’s face using OpenFace software. When processing the data, the multiple linear regression procedure is used. It was found that the dynamics of neighboring key points in the obtained models has a multidirectional char- acter, indicating the presence of a superposition of several dynamic structures, corresponding to the characteristic complex changes in the face position and facial expressions of the sitter. Their isolation is realized by means of the principal component analysis. It is shown, that the first 11 principal components describe 99.7% of the variability of the initial data. The correlation analysis between the number of credibility/confidence statements on the set of time intervals and the principal component loadings, allows to differentiate the dynamic structures of the face, connected with the assessments of credibility of the reported information. Automated analysis of face dynamics optimizes the process of collecting empirical data on the sitter’s appearance and their semantic structuring, as well as expands the range of predictors of the assessments of the truthfulness of the messages received.

Published: July 2021

The paper explores an option to expand the model of mechanisms of insight problem solving proposed by S. Ohlsson. The proposed mechanisms of insight problem solving — chunk decomposition and constraint relaxation — considered within the framework of high-level and low-level processes. Chunk decomposition described as low-level mechanism and constraint relaxation as high-level mechanism. We assume that difficulty of the different insight problems can be explained by high level chunk decomposition and low-level constraint relaxation. The paper describes two experiments dedicated to verify the assumption. The first experiment examines process of solving anagrams (with word) as high-level chunk decomposition. The main results of the experiment show the prospect of distinguishing the semantic chunk decomposition as insight problem solving mechanism. The second experiment use nine-dot insight problem to examine its solution process as relaxation of low-level (perceptual) constraints. Based on the results of the experiments, it can be considered possible to conclude that the expansion of S. Ohlsson’s model of mechanisms of insight problem solving allows to deem the solutions of various problems in a unified system.
Differential types of reflexivity in young people against the backdrop of the COVID-19 epidemic

Published: July 2021

Differential types of reflexivity (as human activities aimed at understanding their own actions) were studied in 66 persons against the background of the COVID-19 epidemic in order to effectively carry out medical, psychological and social interventions in order to maintain epidemiological well-being in society during the current epidemic. It was established that in all examined persons the indicators of scales, the methodology used do not significantly differ from the data obtained earlier by its authors. The surveyed contingent is reliably dominated by systemic reflexion (the indicators of which are comparable to those of those years when there were no such significant global shocks) with a lower (compared to the control group) level of introspection and quasi-reflexion. The bigger variability of data, received by D.A. Leontyev and E.N. Osin, in comparison with our data is caused probably by temporary aspect, various professional contingent of the examined persons, and the relevant processes flowing nowadays in society. Thus, the absence of significant differences from the data obtained earlier is probably due to the cultural and age characteristics of the examined. This indicates the possibility of adequate medical and psychological support for this category of persons against the background of the current COVID-19 pandemic.

Morbidity and mortality from pancreatic cancer is an urgent medical and social problem. Evaluation of statistical indicators in dynamics makes it possible to identify organizational and clinical problems in providing care to patients with malignant neoplasms of the pancreas. Medical and statistical indicators of incidence of malignant pancreatic neoplasms in St. Petersburg residents are evaluated. The assessment of medical and statistical indicators of the incidence of malignant neoplasms of the pancreas in residents of St. Petersburg. Statistical data were studied for the period from 2014 to 2019. The increase in the "rough" indicator of primary morbidity changed from 417.99 per 100 thousand population in 2014 to 505.6 in 2019. In the structure of primary cancer incidence, the indicator of active detection of pancreatic cancer glands in 2014 amounted to 3.6%, in 2019 3.8%. The proportion of patients with diagnoses confirmed morphologically increased from 48.9% to 61.4%. The proportion of patients with newly diagnosed stage IV of the disease changed from 39.5% in 2014 to 51.4% in 2019, and in patients with stage III in 2019 it was 33.3% (a decrease in comparison with 2014 15.3%). In 2019, the disease was diagnosed at stage II in 15.2% of patients. The proportion of patients with stage I in 2019 was 6.6%, this indicator in 2014 was registered at the level of 19.2%. From 2014 to 2019, the one-year mortality rate did not change and amounted to 67.9 and 67.4%, respectively (the decrease was 0.7%). Over the past 5 years, there has been no significant downward trend in the "rough" incidence and mortality rates from pancreatic cancer. However, in the dynamics, there was an increase in the number of patients registered for 5 or more years, and an increase in the accumulation index of the contingent of patients with pancreatic cancer.
Intraoperative seizures occurrence in cortical mapping of eloquent areas

Published: July 2021

The effect of structural epilepsy on the frequency of intraoperative convulsive seizures is assessed when mapping functionally significant areas of the cerebral cortex during resection of intracerebral neoplasms. The work is based on the analysis of the results of intraoperative neurophysiological studies at the Polenov Neurosurgical Institute. For the period 20192020 87 intraoperative mappings of eloquent cortex were carried out during resections of intracerebral neoplasms: 79 mappings of the motor cortex and 16 mappings of auditory-speech areas during operations with awakening. When mapping the motor zones of the cortex, the frequency of seizures was 5.1%, while mapping the auditory-speech zones with awakening 18.75%. The division of cases of intraoperative convulsive seizures into two groups: seizures arising from motor mapping and seizures associated with the mapping of auditory zones reflects differences in factors that affect the excitability of the cerebral cortex. In motor mapping, stimulation occurs against the background of general anesthesia, unlike waking operations. The intensity of stimulation in auditory mapping is higher than in motor mapping in motor mapping. Formally, the current used in motor mapping is significantly higher than in mapping auditory zones. In general, with the development of intraoperative convulsive seizures, the current intensity of cortical stimulation does not exceed the average values required to stimulate functionally significant cortical zones. The presence of epileptic syndrome in patients with intracerebral tumors cannot be considered as a predictor of intraoperative seizure development when performing motor mapping under general anesthesia as well as during surgery with awakening for mapping of motor or auditory verbal zones.

Published: July 2021

In case of antitumour anthracyclines therapy of patients with non-Hodgkin lymphomas the possibility of using speckle-tracking echocardiography is being considered. It was found that patients with non-Hodgkin lymphomas have early violations of the left ventricular myocardium during the course of antitumor chemotherapy using anthracyclines. They are characterized by reducing of longitudinal deformation of the myocardium with a gradual spread from the apical to the basal segments of the left ventricle. A statistically significant reduction in global and segmental systolic deformation after the 4th course of chemotherapy (cumulative dose of doxorubicin 333.5 88.5 mg/m2) is the earliest marker of left ventricular mechanical dysfunction, appearing before the development of diastolic dysfunction and ejection fraction reduction of the left ventricular. Early violations of myocardial mechanics in the dynamics of the course of antitumour therapy with anthracyclines are identified in the apical area of the left ventricle, it can be connected with circulatory failure in this area. Violations of myocardial mechanics in the apical area of the left ventricle can be an erly predictor of ischemia of this area with possible progression to global contractile muscle dysfunction of the left ventricular. The global longitudinall deformation of the left ventricular myocardium in contrast to ejection fraction of the left ventricular is more sensitive to myocardial damages against the backdrop of chemotherapy using anthracyclines. So, it can be used as an early preclinical marker of myocardial damage, that takes echocardiography closer to the most advanced methods of myocardial visualization.

Nuclear and radiation safety remains one of the most important components of the national security of our country. The increasing requirements for the medical care system in the Armed Forces of the Russian Federation in case of peacetime acute radiation injuries are due to the impossibility of completely eliminating the risks of radiation emergencies as a result of natural disasters, industrial radiation accidents and the threat of nuclear terrorism. The peacetime three-level system of medical support in the Armed Forces of the Russian Federation has been developed. It is designed to guarantee the first aid, primary predoctor care, primary doctor care and primary specialized health care for victims of acute radiation injuries by medical units, formations and organizations in the territorial zone of responsibility. In 2017 it was completed a research work "Improving the organization of therapeutic care in acute radiation injuries at the stages of medical evacuation in radiation accidents". An analysis of medical service capabilities to provide specialized, high-tech medical care in radiation injuries showed the relevance of the clinical base development in military medical organizations and the importance of interaction with radiological medical centers of other ministries, agencies and services. The solution of these tasks will be facilitated by the creation of a specialized infrastructure on the basis of military medical organizations of the district (fleet), which is providing necessary conditions for the provision of medical assistance to victims of the radiation emergency.

The article presents up-to-date information about diagnostic methods for one of the most common and socially significant hepatological diseases-alcoholic liver disease. The most frequent clinical manifestations of this pathology are asthenic, dyspeptic, right hypochondrium, cholestatic, neurological, edematous-ascitic and hemorrhagic syndromes. Validated questionnaires are intended for standardized alcohol use screening, the gold standard among which is the AUDIT questionnaire aimed at identifying alcohol use disorders. Most of the physical signs of chronic alcohol abuse are presented in the modified LeGo grid. Direct indicators (markers) of laboratory diagnosis of alcohol use include the determination of phosphatidyl ethanol and ethyl glucuronide in blood serum and urine; ethyl glucuronide and fatty acid ethyl esters in hair; ethanol, aminotransferase, peroxidase, ethylglucuronide, ethyl sulfate, haptoglobin, etc., in saliva. Indirect markers include macrocytic anemia, neutrophilic leukocytosis, increased activity of gamma-glutamyl transpeptidase, transaminases, de Ritis coefficient, bilirubin, alkaline phosphatase, serum immunoglobulin A and gamma globulins. Determination of carbohydrate-deficient transferrin is recommended as a preferred marker of alcohol intoxication. In order to determine the degree of fibrosis, predictive diagnostic serum tests are used, both non-proprietary (APRI, Forns) and commercial (Fibrometer, Hepascore, Fibrospect etc.). The methods of visual diagnostics of liver diseases include ultrasound, magnetic resonance and computed tomography, which can determine steatosis, exclude other causes of liver damage, reveal signs of severe fibrosis or cirrhosis, as well as their complications, but none of them allows to establish the etiology of the lesion. A promising direction is to determine the degree of steatosis when measuring the controlled parameter of ultrasound attenuation, implemented in the Fibroscan apparatus. The most accurate methods for diagnosing steatosis today are magnetic resonance imaging of the liver in the mode of determining the proportion of fat, weighted by proton density, and proton magnetic resonance spectroscopy. To determine the degree of fibrosis, a transient, two-dimensional shear wave and magnetic resonance elastography are used. Biopsy followed by morphological examination is the gold standard for the diagnosis of alcoholic liver disease, which confirms the presence of liver damage, establishes its stage and often allows confirming alcoholic genesis. However, this procedure has a number of significant drawbacks, so it is advisable to use non-invasive diagnostic techniques for screening, primary examination and further monitoring of the patients condition in dynamics.
Artificial intelligence using for medical diagnosis via implementation of expert systems

Modern biomedical technologies development affords to provide the doctor with colossal amount of information about patients organism condition. However, the opportunity of using this data for medical diagnosis fully now is a distantive perspective only. The reason is a humans limited ability in assessment and interpretation this data arrays. The solution seems in artificial intelligence and expert systems wide introduction to medicine. Currently, almost all authors consider various options for constructing artificial neural networks as a way to implement artificial intelligence. This approach, which goes back to the fundamental theorem of A.N. Kolmogorov, the works of V.I. Arnold and Hecht-Nielsen [3], demonstrates excellent capabilities in a number of pattern recognition problems, which are reduced to revealing hidden details against the background of input noises. Much less often is mentioned such a method of modeling formal thinking as expert systems, which arose in the 1960s and then went into the shadows. Since the inception of cybernetics, computer programmers have tried to reproduce the mechanism of human thinking, that is, the task was to teach the computer to "think". The first known results in the field of creating and using intelligent systems were laid by the work of Norbert Wiener and G.S. Altshuller. At the same time, the creation of intelligent systems was reduced to the development of programs that solve problems using a variety of heuristic methods based on the property of human thinking to generalize.

The issues of psychosocial and other impact of COVID-19 on the epidemiological specificity of the disease are considered in the interests of effective medical, psychological and social interventions to preserve the epidemiological well-being in society during the period of the COVID-19. It is shown that the spread of this disease had a sharply negative impact on the economy, in particular, of our country, since for a long time certain industries that served as sources of budget revenues were paralyzed, and the populations ability to pay sharply decreased, the volume of financial inflows into the service sector decreased, which is reflected in the field of public health. Therefore, within the framework of the anti-crisis COVID-19 measures, one can single out such areas as education, employment, support for vulnerable groups and information support, which are carried out in various countries based on the existing practices, methods and financial capabilities. In addition, the fact that the current outbreak of COVID-19 provokes stigmatization and discriminatory behavior of society towards representatives of certain ethnic groups, as well as towards people suspected of having contact with carriers of the SARS-CoV-2 coronavirus infection, is of great epidemiological significance. The widespread prevalence of COVID-19 is believed to be not a pandemic, but a syndemia (not just comorbidity, but an integration that identifies biological and social interactions important for prognosis, treatment and health policy), characterized by biological and social interactions between conditions and conditions, interactions that increase a persons susceptibility to harm or worsen their health. Thus, in the case of COVID-19, the fight against non-communicable diseases (hypertension, obesity, diabetes, cardiovascular and chronic respiratory diseases, cancer, snake bites, epilepsy, kidney disease and sickle cell anemia) and socioeconomic inequality will also become a prerequisite for its successful containment.
