This study analyzes various publications of scientists on the training of future IT specialists and the features of training programming using online simulators. The authors of the article made a comparative description of different online platforms for teaching programming according to certain criteria, selected interesting tasks from the online platform hackerrank.com, which have already been used to teach students. Online programming simulators have significant potential in organizing an effective distance learning system in Ukrainian universities. It is important to use online simulators in the learning process as an additional tool for the formation of professional competencies, which provides more intensive involvement of students in the process of writing code and practical (situational) application of existing knowledge. Gamification of the process of training future IT specialists helps to increase cognitive activity, and hence – the quality of the educational process and distance learning in particular. The authors recommend the use of online programming simulators as an additional tool for teaching computer science disciplines, taking into account their functionality, as well as the level of preparation of students and the expected learning outcomes.
It is proved that in the conditions of the information society, the analysis of platforms and tools of open education and the use of leading information and communication technologies is important. The article discusses conceptual foundations of "open education" as the successor to the conventional education system. The basic characteristics of open education are considered. The purpose of the article is to systematize and determine the essential characteristics of the world's leading platforms and tools for using information and communication technologies in educational institutions in the process of modernizing the education system in Ukraine. The main object of research is an open education system. The methodology of the study consists of such methods as: the method of historical research, generalization, expert assessment, the questionnaire method, analysis and systematization. The article systematizes and characterizes the world's leading approaches to the use of information and communication technologies in educational institutions in the process of modernizing modern educational systems in accordance with the latest requirements of the information society. The necessity of high-quality filling of the system of "total computer literacy" and total digitalization of the national education system by introducing modern platforms and tools of open education, cloud services, modern technical equipment and software, the entry of the national education system into the global educational space at the institutional, environmental level is substantiated and personal level. It is concluded that today, in relation to the modernization of the national education system, our state faces the difficult task of ensuring that the basic approaches, principles and tools of the educational process meet the requirements of the transition to the era of the information society. The main platforms and digitalization tools of open education are considered. Based on the expert assessment methods and the questionnaire method, the most optimal methods of open education were chosen for higher educational institutions of Ukraine.
The article contains research on use of open and specialized geoinformation systems to prepare students and postgraduates on specialties: 101 “Environmental Sciences”, 103 “Earth Sciences”, 122 “Computer Sciences”, 183 “Environmental Technologies”. Analysis of the most common world open geoinformation systems is done. Experience of geoinformation systems use for students and postgraduates teaching for different specialties is described. Predominant orientation towards the use of geoinformation systems in educational process is determined based on the analysis of scientific publications and curricula of the most popular Ukrainian universities. According to the authors the material that is given narrows knowledge and skills of students and postgraduates, particularly in computer modeling. It is concluded that ability of students and postgraduates to use geoinformation systems is interdisciplinary. In particular, it develops knowledge and skills in computer modeling of various processes that may arise in the further professional activity. Examples of professional issues and ways to solve them using geoinformation systems are given. Recommendations are given on the use of open and specialized geoinformation systems in the educational process. It is recommended to use both proprietary (ArcGis, MapInfo) and open GIS (uDIG, QGIS, Whitebox GAT) to teach students. Open GIS (uDIG, QGIS, Whitebox GAT) and specialized (Modular GIS Environment, GEO + CAD, GeoniCS, AISEEM) can be used to teach both students and postgraduates.
The aim – to study the clinical, anamnestic and instrumental parameters associated with short-term prognosis in patients with pulmonary embolism (PE). Materials and methods. This study was conducted from September 1, 2019 to December 31, 2020 on the basis of the city clinical hospital. The preliminary analysis included 187 patients with acute pulmonary embolism. The study found that 25 (13.3 %) patients died within 30 days (group I): 19 (76.0 %) patients belonged to a high risk of predicted early death and 6 (24.0 %) – to intermediate-high risk. For further analysis, a comparison group (group II) was formed and included 106 (56.7 %) patients who survived within 30 days of the onset of an acute episode of PE: 54 (50.9 %) patients belonged to high risk, 52 (49.1 %) – to intermediate high risk. All patients with pulmonary embolism received anticoagulant therapy according to the current ESC guidelines. Results. The average age of patients in group I was 69.08 ± 14.15 years and was significantly higher than in group II: 65.25 ± 13.29 (p = 0.0169). The proportion of high-risk patients was significantly greater in the І group, the proportion of patients of intermediate-high risk was significantly greater in group II (p = 0.0409). The incidence of classes IV and V according to the PESI index, assessed in patients of intermediate-high risk, was the same in both groups, while patients with the PESI index class III prevailed in group II (p = 0.0380). The risk factors for venous thromboembolism occurred more frequently in patients of group I, i.e. congestive heart failure (p = 0.0065) and obesity (p = 0.0482). Conclusions. There is a high mortality rate within 30 days (13.3 %) in hospitalized patients with acute PE, including 26 % of high-risk patients and 10.3 % of intermediate-high risk. Age over 65 years, the presence of congestive heart failure and obesity are independent factors that, according to uni- and multivariate logistic regression analysis, are associated with poor short-term prognosis in patients with PE. Key words: pulmonary embolism, venous thromboembolism, short-term prognosis, anticoagulant therapy.
Background. The purpose was the analysis of the features of the course and the leading factors in the development of pulmonary embolism. Materials and methods. During the period from November 1, 2019, to December 2020, inclusive, 188 patients with acute pulmonary embolism (PE), aged 46 to 80 years old, were hospitalized at the City Clinical Hospital 8 of the Kharkiv City Council; the average age was 62.9 ± 16.7 years. In-hospital mortality was 12.2 % (23 patients). The criterion for inclusion in the study was acute PE, which was diagnosed based on the results of multislice computed tomographic angiography of the pulmonary arteries (MCT angiography of the pulmonary arteries). All patients underwent a general clinical examination, the risk and prognosis were assessed based on the generally accepted scales, standard transthoracic echocardiography (EchoCG), and Doppler ultrasound examination of the veins of the lower extremities were performed. Results. The disease was diagnosed with the same frequency in men and women; there was no difference in age. Among the most significant and important risk factors for the development of pulmonary embolism are the history of venous thrombosis/embolism and active malignant oncological disease (43 and 35 %, respectively), while the less significant ones were advanced age, varicose veins of the lower extremities and arterial hypertension 47.9, 31.4 and 52.1 %, respectively. The vast majority (57.4 %) had a combination of 2 or more risk factors. Signs of right ventricular dysfunction according to MCT angiography of the pulmonary arteries and/or echocardiography were recorded in 45.7 % of patients. A high and medium-high risk of early death associated with acute PE was found in a significant percentage (71.8 %) of patients, which required the inclusion of a thrombolytic agent in the treatment strategy.
