WMO is coordinating the efforts to build a data space for hydrology, called the WMO Hydrological Observing System (WHOS). Hydrological datasets have intrinsic value and are worth the enormous human, technological and financial resources required to collect them over long periods of time. Their value is maximized when data is open, of quality, discoverable, accessible, interoperable, standardized, and addressing user needs, enabling various sector users to use and reuse the data. It is essential that hydrological data management and exchange is implemented effectively to maximize the benefits of data collection and optimize reuse.WHOS provides a service-oriented framework that connects data providers to data consumers. It realizes a system of systems that provides registry, discovery, and access capabilities to hydrology data at different levels (local, basin, regional, global). In 2015, the World Meteorological Congress supported the full implementation of WHOS, which is currently publicly available at https://community.wmo.int/activity-areas/wmo-hydrological-observing-system-whos, along with information for both end users and data providers about how to use and join it.End users (such as hydrologists, forecasters, decision makers, general public, academia) can discover, access, download and further process hydrological data available through WHOS portal by means of their preferred clients (web applications, tools and libraries).Data providers (such as National Meteorological and Hydrological Services - NMHSs, river basin authorities, private companies, academia) can share their data through WHOS by publishing it online by means of machine-to-machine web services.The brokering approach powered by the Discovery and Access Broker (DAB) technology enables the interoperability between data providers’ services and end users’ clients. A mediation layer implemented by the DAB brokering framework mediates between the different standard protocols and data models used by both providers and consumers to seamlessly enable the data flow from heterogeneous data providers to the clients of each end user.In parallel, WHOS experts are working in constant collaboration with the data providers to support the implementation of the latest standards required by the international guidelines (e.g., WaterML2.0 and WIGOS Metadata Standard), optimize the data publication and improve the metadata and data quality.The WHOS Distance Learning course has been successfully conducted; attenders from NMHSs were provided updated information and guidelines to optimize their hydrological data sharing. The course is currently being translated into Spanish to carry out it for Spanish speaking countries in 2023.WHOS is a hydrological component of WMO Information System (WIS), which is currently in its pilot phase. WHOS and WIS Interoperability tests are currently being piloted and expected to end in 2023. The aim of this interoperability is to promote smooth data exchange between Hydrology community and the wider WMO community. Finally, hydrological data shared through WHOS will be accessible to general WIS users (all piloted programmes, including climate through OpenCDMS, and cryoshere) and at the same time WHOS users will make use of observations made available by WIS.

International audience; Two thirds of hydrological observation networks in developing countries are reported to be in poor or declining condition. At the same time innovation in sensor technologies and data processing are presenting opportunities for enhancing observation networks that are not being realized. The World Meteorological Organization’s Global Hydrometry Support Facility, or WMO HydroHub, was launched in 2016 to transform assistance to operational water monitoring agencies around the world. If successful, the initiative will increase the amount of hydrometric data available to researchers, catchment managers and water policy makers. To those unfamiliar with UN organizations, however, the nature of such initiatives, the reasoning behind the decisions taken to establish them and the mechanisms by which they try to deliver benefits for society, can be opaque. This paper adopts a novel dialogue-style format to explore the set-up of the WMO HydroHub and build awareness amongst those who ultimately may benefit from its approaches.

Background. The Ross operation was first proposed in 1967 by D. Ross, and numerous studies have shown that it has excellent long-term results. However, in some patients, it can lead to late dilatation of the pulmonary autograft, which in turn can contribute to repeat operations. To avoid this complication, technical modifications of the Ross operation have been proposed.Aim. To evaluate the immediate and five-year outcomes of the modified Ross surgery in adults.Methods. This retrospective study included patients aged 18 years and older with aortic valve lesions who underwent a modified Ross procedure by one surgeon between January 2014 and December 2019. The median follow-up period was 23 (12–68) months.Results. The study included 43 adult patients. The average age of the patients was 40.0 ± 11.7 years, and 33 (76.7%) were men. The main cause of aortic valve dysfunction was severe aortic regurgitation (32 patients, 74.4%). Infective endocarditis was diagnosed as a cause of aortic valve pathology in 13 (30.2%) patients. Bicuspid aortic valve was present in 29 cases (67.4%). In two cases (4.7%), mini-sternotomy (‘T-shape’) was performed. Ten (23.2%) patients underwent combined interventions. The median duration of cardiopulmonary bypass was 143 (129–160) minutes, and duration of aortic cross-clamp was 116 (109–131) minutes. The autologous inclusion technique was used in 22 (51.2%) cases and the Dacron inclusion technique in 21 (48.8%) cases. Outcomes included no in-hospital mortality, acute renal failure requiring haemodialysis in three patients (7%), pacemaker implantation in two (4.7%), resternotomy for bleeding and stroke in one patient (2.3%) and perioperative myocardial injury in two (4.7%). The five-year overall survival, freedom from reoperation and freedom from dilatation of the ascending aorta or pulmonary autograft ≥ 5 cm after the modified Ross operation were 97.4%, 100.0% and 100.0%, respectively.Conclusion. Modified Ross surgery in adults has excellent immediate outcomes with no in-hospital mortality. The five-year overall survival, freedom from reoperation and freedom from aortic dilatation or pulmonary autograft were 97.4%, 100.0% and 100.0%, respectively.Received 15 February 2021.

The aim of the research was to study the effect of chronic alcohol intoxication and constant il-lumination on the circadian rhythms (CR) of some parameters of the cardiovascular system in rats separately, as well as to study the rhythms of these parameters under the combined action of chronic alcohol intoxication (CAI) and constant illumination. It was found that chronic alcohol intoxication CAI at a fixed light regime causes a decrease in heart rate, an increase in SBP and PP; no changes were noted at CAI under constant lighting. At the same time, constant illumina-tion without ethanol exposure results in a decrease in heart rate and an increase in PP. At the same time, CAI with a fixed light regime leads to the destruction of CR of all parameters, except for MBP; at constant illumination with CAI no circadian rhythms of HR, DBP, PP and MBP are detected. Constant illumination leads to the destruction of the CR of PP. Among the remaining CRs, the heart rate rhythm, which is extant in the second group, persists practically unchanged, but the characteristics of all other CRs change significantly in comparison with control.

Introduction. Alcohol abuse is one of major health and social problems of modern society, the essence of which is an increase in morbidity and mortality not only from alcohol misuse and its complications, but also from associated comorbid pathologies. The liver is the organ that is affected most by ethanol and its metabolites. A significant factor leading to melatonin-associated morphological manifestations in the liver is the so-called light pollution, a violation of the light–dark regime. At the same time, heavy consumption of alcohol over a short period of time (alcoholic excesses) and other forms of alcoholic illness are often associated with various sleep disorders. The aim of the study was to investigate the morphological and functional state of the liver of Wistar rats under experimental alcohol intoxication in conditions of a fixed light regime and constant illumination. Materials and methods. Male rats (n=160) were kept under a fixed light regime, constant illumination, and at a combination of both light regimes with simultaneous experimental alcohol intoxication. We performed a pathological examination of the liver and determined morphometric parameters, hepatocyte ploidy, and the proportion of binuclear hepatocytes. Results. The consumption of 15% ethanol solution as a drink ad libitum for 3 weeks at a fixed light regime causes the development of fatty degeneration in the liver of laboratory animals. Secondary to it, changing lighting from fixed to constant is accompanied by the development of alcoholic hepatitis in about half of the animals. The results of micromorphometry indicate significant changes in the studied parameters of hepatocytes, which are expressed least of all in the case of ethanol consumption under fixed lighting condi-tions and affect most the cells of the liver parenchyma of rats with chronic alcohol intoxication secondary to constant lighting. Conclusion. Alcohol intoxication that occurs secondary to a melatonin deficiency caused by constant lighting is accompanied by a much greater severity, prevalence, and intensity of inflammatory tissue reactions and a variety of manifestations of liver pathology. Keywords: hepatocyte, alcohol, lighting regime, stress, fatty degeneration

The use of signals with spectrum expansion allows us to effectively solve the problems of multi-station access to a repeater for a large number of subscribers. The article presents a study of signals with spectrum extension to protect satellite communication lines from possible interference. Directions for further experimental research are recommended.

Background: Patients with aortic stenosis (AS) and small aortic annulus (SAA) who undergo surgical aortic valve replacement (SAVR) are more likely to receive smaller prostheses, predisposing them to prosthesis patient-mismatch (PPM). Since the Ozaki Procedure (aortic valve neocuspidization–AVNeo) has proved promising, we aimed to assess its immediate results in this scenario. Methods: AVNeo was performed in 106 consecutive patients from January 2017 to March 2019 at three centers. The records were prospectively collected and reviewed retrospectively. Most of the patients were older than 60 years and 97.2% had AS. Preoperative echocardiography showed average peak pressure gradient of 64.9±20.7mmHg and mean pressure gradient of 46.0±12.2mm Hg for patients with AS and an annular diameter of 19.8±1.1mm for all patients. EOA and iEOA averaged 0.7±0.2 cm2 and 0.4±0.2cm2/m2 before surgery, respectively. Results: There was no conversion to SAVR. Four patients needed reoperation for bleeding, but none needed reoperation due to early infective endocarditis. Median intensive care unit and hospital length of stay were 1.5±1.2 and 13.7± 5.1 days, respectively. There were 2 in-hospital deaths due to non-cardiac causes. Postoperative peak pressure gradient averaged 11.8±5.9mmHg and mean pressure gradient averaged 7.3±3.5mmHg, which means statistically significant average decreases of 58.1 and 38.7 mmHg, respectively. Postoperative EOA and iEOA averaged 2.5±0.4cm2 and 1.3±0.3cm2/m2, which means statistically significant average increases of 1.8cm2 and 0.9cm2/m2, respectively. Conclusions: AVNeo is feasible and reproducible with good immediate results. Our findings show that AVNeo produces immediate postoperative low-pressure gradients, larger EOA and minimal regurgitation of the aortic valve. CA extern

The features of the diurnal dynamics of the area of rat hepatocyte nuclei and their ploidy were studied under conditions of a standart (fixed) light regime and constant illumination, as well as under chronic exposure to alcohol in the mentioned light regimes. It has been shown that exposure to alcohol and exposure to constant illumination separately lead to a change in the amplitude-phase characteristics of the circadian rhythm of the nucleus area, while the combined effect of these factors leads to a complete destruction of the rhythm, which indicates a violation of adaptation processes. An increase in the average ploidy of hepatocyte nuclei in chronic alcohol intoxication is also shown, while in animals kept under constant illumination without drinking alcohol, the values of this parameter decrease, which indicates a successful course of the adaptation process. The conducted research indicates that the results of karyometric and ploidometric analysis characterize the degree of influence of alcohol intoxication and changes in the light regime on the liver of rats, reflecting the rate of efficiency of adaptation to these factors.

INTRODUCTION: The objective of this study was to identify risk factors for deep sternal wound infection (DSWI) after off-pump coronary artery bypass (OPCAB) grafting surgery.METHODS: A total of 8,442 patients undergoing OPCAB from April 1, 2009 to December 31, 2018 were retrospectively analyzed. A total of 956 were eventually enrolled on this study based on our exclusion criteria. All subjects were divided into two groups: group 1 (n=63) - DSWI; group 2 (n=893) - without DSWI. Patients were excluded if they had one of the following: acute coronary syndrome, conversion to OPCAB grafting surgery, redo procedure, concomitant cardiac surgery procedures.RESULTS: The prevalence of body mass index (BMI) ≥40 kg/m2 (7.9% vs. 1.9%, respectively; P=0.01), lower extremity atherosclerotic artery disease (23.8% vs. 7.2%, respectively; P=0.001) and use of bilateral internal thoracic artery (19.5% vs. 2.5%, respectively; P=0.008) was significantly higher in patients with DSWI. The incidence of morbidities, including reoperation for bleeding (26.4% vs. 2.1%, respectively; PCONCLUSIONS: A BMI of >40 kg/m2, lower extremity artery disease, use of bilateral internal thoracic artery (BITA) graft, postoperative stroke, sepsis, reoperation due to postoperative complications and blood product requirement significantly increased the risk of sternal infection after OPCAB.

Objective The main purpose of this article is to evaluate an impact of epicardial ligation of the left atrial appendage (LAA) in patients with atrial fibrillation (AF) undergoing off-pump coronary artery bypass grafting (OPCAB) on the development of ischemic stroke and mortality. Methods From 2009 to 2013, a total of 125 patients (86.4% men, mean age 64 ± 7 years, 95% confidence interval: 61–65 years) received a combined OPCAB and LAA ligation because of coronary artery disease and AF. All the subjects were divided into two groups: group 1 (n = 57)—LAA ligation during OPCAB, group 2 (n = 68) without LAA ligation during OPCAB. Primary endpoints were postoperative incidence of ischemic stroke and mortality. Results No difference in the number of ischemic stroke (0 vs. 5.9%) and death (0 vs. 4.4%) in both groups during the hospital period (p > 0.05). Median overall follow-up was 41 (22–61) months: without difference for groups (p > 0.05). During follow-up, there was a difference in the number of ischemic stroke (0 vs. 17.6%, p 0.05). Conclusion Epicardial ligation of LAA during OPCAB in patients with AF may reduce the risk of ischemic stroke in long-term follow-up and does not affect the mortality.

Aim. To evaluate the results of surgical treatment of post-infarction left ventricular aneurysms with on-pump beating heart technique. Methods. In our center from April, 2009 to January, 2014 169 patients had reconstruction of the left ventricle with on-pump beating heart technique. Among the patients 159 were males (94.1%) and 10 of them were females (5.9%), average age 53.8±8.9 years (39 to 72 years). Angina pectoris class I (according to the classification of Canadian Heart Association) was established in 7 (4.1%) patients, class II - in 49 (29.0%), class III - in 107 (63.3%), class IV - in 4 (2.4%), unstable angina in 2 (1.2%) patients. Chronic heart failure class I (according to New York Heart association functional classification) was diagnosed in 5 (3.0%) patients, class II in 37 (21.9%), class III in 124 (73.4%), class IV in 3 (1.8%) patients. Average ejection fraction of the left ventricle was 38.6±7.9% (25 to 67%). Mitral valve insufficiency stage 2-3 was revealed in 23 (13.6%) patients. Results. Endoventriculoplasty of the left ventricle by Dor's technique was performed in 49 (29.0%) patients, auto-septoplasty of the left ventricle - 59 (34.9%) patients, linear repair in 40 (23.7%) patients. Combined surgical interventions were performed in 21 (12.4%) patients. In-hospital lethality was 2.4% (n=4). Conclusion. Left ventricular reconstruction with on-pump beating heart technique without cardioplegic arest is effective and safe; the method allows performing remodelling of the left ventricle and reaching the target volume parameters.

The WMO Commission of Hydrology (CHy) is realizing the WMO Hydrological Observing System (WHOS), a software (and human) framework with the aim of improving sharing of hydrological data and knowledge worldwide.National Hydrological Services (NHS) are already sharing on the web (both archived and near real time) data collected in each country, using disparate publication services. WHOS is leveraging the Discovery and Access Broker (DAB) technology developed and operated in its cloud infrastructure by CNR-IIA to realize WHOS-broker, a key component of WHOS architecture. WHOS-broker is in charge of harmonizing the available and heterogeneous metadata, data and services making the already published information more accessible to scientists (e.g. modelers), decision makers and general public worldwide. WHOS-broker supports many service interfaces and API that hydrological application builders already can leverage, example given OGC SOS, OGC CSW, OGC WMS, ESRI Feature Service, CUAHSI WaterOneFlow, DAB REST API, USGS RDB, OAI-PMH/WIGOS, THREDDS. New API and service protocols are continuously added to support new applications, being WHOS-broker a modular and flexible framework with the aim of enabling interoperability and assuring it as the standards will change/evolve through time. Three target programmes have already benefited from WHOS:La Plata river basin: hydro and meteo data from Argentina, Bolivia, Brazil, Paraguay, Uruguay are harmonized and shared by WHOS-broker to the benefit of different applications, one of them is the Plata Basin Hydrometeorological Forecasting and Early Warning System (PROHMSAT-Plata model, developed by HRC), based on CUAHSI WaterOneFlow and experts from the five countries. Arctic-HYCOS: hydro data from Canada, Finland, Greenland, Iceland, Norway, Russia, United States are harmonized and shared by WHOS-broker to the benefit of different applications, one of them is the WMO HydroHub Arctic portal, based on ESRI technologies. Dominican Republic: hydro and meteo data of Dominican Republic published by different originators is being harmonized by WHOS-broker to the benefit of different applications, one of them is the Met data explorer application developed by BYU based on THREDDS catalog service. The three programmes should act as a driving force for more to follow, by demonstrating possible applications that can be built on top of WHOS.The public launch of WHOS official homepage at WMO is expected by mid 2021, will include:A dedicated web portal based on Water Data Explorer application developed by BYU Results from the three programs Detailed information on how to access WHOS data by using one of the many WHOS-broker service interfaces An online training course for data providers interested in WHOS The WHOS Hydro Ontology, leveraged by WHOS-broker in order to both semantically augment user queries and harmonize results (e.g. in case of synonyms of the same concept in different languages).

This paper is aimed at identifying key stages in the development of the so-called ‘linguistic-political realism’ in the theory of international relations (IR). It is trough language that the paradox of the impossibility of comprehending the objective social world without the aid of its subjective description is lifted. From the viewpoint of linguistics, human language as the basic sign system has numerous functions, the most important of which are the cognitive and the communicative functions. The cognitive function consists in that linguistic signs enable humans to think, i.e., the nature of our consciousness is tied to signs. It is therefore due to this function that the whole real world (both physical and social) around us is accessible for us only through language. The communicative function of language enables any interaction between individuals, and thus creates all social forms (society, state, nation etc.). ‘Linguistic-political realism’ is understood as a strand of social philosophical enquiry (irrespective of authors’ ontological position) which specifically distinguishes an ‘objective’ role of the language factor in both the development of an individual society and the interaction of societies speaking different languages. Consideration is given to elements of linguistic-political realism in various social philosophical approaches from antiquity to Marxism, which was the last integral philosophical system and predated the emergence of sociology and International Relations theory as separate academic disciplines.

New age of globalization and regionalism unavoidably change a political geography and political discourse. The paper examines how the globalization and regionalism transform the traditional Russian identity. The paper discusses the possibility of its movement towards the values of “open society” and multiculturalism. In this paper, we study the impact of globalization to the civilizational identity of Russia. Does globalization erase the issue of nationalism, or does it do the opposite and sharpen the existing contradictions?

Robotic grasping has been a prevailing problem ever since humans began creating robots to execute human-like tasks. The problems are usually due to the involvement of moving parts and sensors. Inaccuracy in sensor data usually leads to unexpected results. Researchers have used a variety of sensors for improving manipulation tasks in robots. We focus specifically on grasping unknown objects using mobile service robots. An approach using convolutional neural networks to generate grasp points in a scene using RGBD sensor data is proposed. Two convolutional neural networks that perform grasp detection in a top down scenario are evaluated, enhanced and compared in a more general scenario. Experiments are performed in a simulated environment as well as the real world. The results are used to understand how the difference in sensor data can affect grasping and enhancements are made to overcome these effects and to optimize the solution.

Objective: To determine the feasibility of aortic valve neocuspidization (AVNeo) with glutaraldehyde-treated autologous pericardium. Methods: One hundred and seventy (170) AVNeo (84 males/86 females) were performed from January 2017 through March 2019 in three centers. All the records were prospectively collected and retrospectively reviewed. Results: Most of the patients were older than 60 years and over 95% were operated for aortic stenosis. Preoperatively, pressure gradients were 69.9±21.3 mmHg for patients with aortic stenosis, and the surgical annular diameter was 21.0±2.0 mm for all patients. Effective orifice area (EOA) and indexed EOA (iEOA) averaged 0.7±0.3 cm2 and 0.4±0.2 cm2/m2 for patients with aortic stenosis before surgery, respectively. There was no conversion to prosthetic aortic valve replacement. Eight patients needed reoperation for bleeding, but no patient needed reoperation due to early infective endocarditis. There were five in-hospital deaths due to noncardiac cause. Compared to preoperative echocardiographic measurements, postoperative peak pressure gradient decreased significantly (-58.7±1.7 mmHg; P mild). Conclusion: AVNeo is feasible and reproducible with good clinical results. Hemodynamically, AVNeo produces immediate postoperative low-pressure gradients, large EOA, and minimal regurgitation of the aortic valve. Further studies are necessary to evaluate mid- and long-term evolution.

Objective: To compare the in-hospital outcomes of a right-sided anterolateral minithoracotomy with those of median sternotomy in patients who received a mitral valve replacement (MVR) because of rheumatic mitral valve stenosis (RMS). Methods: This is a retrospective analysis of 128 patients (34% male) with RMS between 2011 and 2015. The median age was 53 years (45; 56). The mean ejection fraction was 58.4±6.3%. All the subjects were divided into two groups - Group 1 contained 78 patients who underwent MVR via minithoracotomy (MT-MVR), while Group 2 contained 50 patients who underwent MVR via median sternotomy (S-MVR). Results: In the MT-MVR group, a mechanical prosthesis was implanted in 72% of cases, while it was implanted in 90% of cases in the S-MVR group (P=0.01). The duration of myocardial ischemia was similar (MT-MVR, 77±24 min; S-MVR, 70±18 min) (P=0.09). However, the cardiopulmonary bypass time was lower in the S-MVR group than in the MT-MVR group (99±24 min and 119±34 min, respectively) (P≤0.001). There was no difference in the duration of mechanical ventilation, intensive care unit stay, and hospitalization period. Postoperative blood loss was lower in the MT-MVR group (P≤0.001) than in the S-MVR group. There are no statistically significant differences in postoperative complications (superficial wound infection, stroke, delirium, pericardial tamponade, pleural puncture, acute kidney insufficiency, and implantation of pacemaker). The overall in-hospital mortality was 3.9% (P=0.6) Conclusion: The minimally invasive approach for RMS is feasible and has an excellent cosmetic effect without increasing the risk of surgical complications.

The paper deals with the influence of e-government implementation on the struggle against corruption in Azerbaijan. We draw a conclusion that e-government implementation within the existing governing bodies can decrease corruption only to the certain point, corresponding the level of “overwhelming computerization” of the population.

We present the design and development of an open-source web application called Water Data Explorer (WDE), designed to retrieve water resources observation and model data from data catalogs that follow the WaterOneFlow and WaterML Service-Oriented Architecture standards. WDE is a fully customizable web application built using the Tethys Platform development environment. As it is open source, it can be deployed on the web servers of international government agencies, non-governmental organizations, research teams, and others. Water Data Explorer provides uniform access to international data catalogs, such as the Consortium of Universities for the Advancement of Hydrologic Science (CUAHSI) Hydrologic Information System (HIS) and the World Meteorological Organization (WMO) Hydrological Observing System (WHOS), as well as to local data catalogs that support the WaterOneFlow and WaterML standards. WDE supports data discovery, visualization, downloading, and basic data interpolation. It can be customized for different regions by modifying the user interface (i.e., localization), as well as by including pre-defined data catalogs and data sources. Access to WDE functionality is provided by a new open-source Python package called “Pywaterml” which provides programmable access to WDE methods to discover, visualize, download, and interpolate data. We present two case studies that access the CUAHSI HIS and WHOS catalogs and demonstrate regional customization, data discovery from WaterOneFlow web services, data visualization of time series observations, and data downloading.

In aortic valve disease cases, prosthetic valves have been used for valve replacement, however, these prostheses have inherent problems, and their quality in some countries is lower comparing to new-generation models, causing shorter durability. Aortic valve neocuspidization (AVNeo) has emerged as an option, which can be applied to a wide spectrum of these diseases. Despite the promising results, this procedure is not widely spread among cardiac surgeons yet. We developed a surgical technique combining Bentall and Ozaki procedures to treat patients with concomitant ascending aorta replacement and AVNeo and we describe it in this paper. The Russian conduit – combination of Bentall and Ozaki procedures.

The study examines the main vectors of the impact of social networks on the form of political struggle, which, although partly acquiring a virtual nature, does not change its content. Based on the analysis of quantitative data of “Yellow vests” protest sites, as well as surveys on the social structure of the participants, the study deals with the technology origin and functioning of a new phenomenon of political linguistic and communicative community, acting in the social networks and is not connected with the traditional “really organized” political institutions and groups. The study focuses on the “political power” of this virtual community, i.e. limits of its influence on political decision-making at the national level.

This case study is an example of interdisciplinary research, which couples the linguistic aspects with the study of public political discourse in social media. The purpose of the study is to identify how “realism” terms and national/global agenda are represented in Twitter discourse of leaders of countries which claim to be global powers today. Obviously, it is impossible to claim a high status in the modern world without participation in global discussions (including the level of influence on public opinion in Twitter). We collect data from official accounts of the U.S. President Donald Trump, France’s President Emmanuel Macron, Russia’s President Vladimir Putin, and Russia’s Prime Minister Dmitry Medvedev. Then we propose a research method developed by us which contains 5 stages. The main method of research is traditional content analysis, not only selective (under this or that theory), but also “front-line” one. We are interested in the subject matter (key, most frequent vocabulary) that dominates the considered texts. We separate the same amounts of text (approximately 33 000 words) in the content of the Twitter pages of Trump, Macron, Putin and Medvedev. Then we quantify the words and identify the key concepts which are specific for political realism and political idealism. We perform a “frontal” general analysis of all the most frequently used concepts. We make a quantitative assessment of the nature of the use of political leaders’ key concepts (this stage of analysis is divided on several sub-stages). Finally we compare the frequency of concepts’ use by leaders of the West and Russia.

This paper focuses on the transformation of digital strategies and activities of international organizations (cases of Francophonie and Eurasian Economic Union). We do not compare digital strategies of two organizations. We use two levels (legal and practical) to analyze strategies, institutions and experience (policies) of two organizations. We analyze the priorities mentioned in digital strategies as well as terms, goals, and bodies in charge.
