Sialolithiasis is one of the most common and extensively obstructive disorders of the major salivary glands. Here, we report 3 cases of sialolithiasis in the submandibular salivary gland showing symptomatic similarities to other dental and non-dental disorders of the maxillofacial area. How the various clinical features of this condition and findings on 3D-CT may lead to a misdiagnosis are also discussed. In the first case, that of a 45-year-old woman, a final diagnosis of a non-radiopaque submandibular sialolith allowed the initially indicated surgical extraction of a malerupted and semi-impacted right mandibular 3rd molar to be abandoned. In the second case, that of a 57-year-old woman, radiographic findings had previously led to a diagnosis of ameloblastoma, which had masked the presence of sialolithiasis for at least 9 years, despite the radiopacity of the sialolith. Meanwhile, exacerbation of sialolithiasis was mistaken for lymphadenitis. In the third case, that of a 40-year-old woman, sialolithiasis was diagnosed in a timely manner, despite the fact that the dentists' attention had initially been focused on odontopathological symptoms. One feature of the present report is the concurrence of dental and non-dental pathologies affecting the same sextant as the sialolithiasis. Despite recent advances in imaging technology and diagnostics, cases of sialolithiasis being misdiagnosed continue to occur in clinical practice.

The article considers raising students' media literacy as the response to the pandemic challenges highlighting the problem of deficiency of information verifiability and the importance of raising students' critical thinking as a crucial tool in decreasing the COVID-19 pandemic potential damage. The focus of the study lies in the research what sources/genres students of technical universities resort to in getting the information concerning the pandemic, what is their ability to distinguish facts from opinions, trustworthy information from misinformation as well as what are possible differences among students of technical and humanitarian specialities in terms of media literacy. The findings of the survey of 511 students majoring in different specialities at the National Technical University of Ukraine' Igor Sikorsky Kyiv Polytechnic Institute' (after this, the official abbreviated name – Igor Sikorsky KPI) revealed a need in raising students' media literacy in terms of critically assessing information concerning the coronavirus.

The paper highlights, analyses and interprets the results of the pedagogical experiment on applying the authors' teaching methodology to form students' terminological competence in bilateral interpreting in the Moodle-based e-learning course. It is stated that online instruction as a competitive option to regular forms of classroom learning is establishing an apparent connection between students' outcomes of learning and the modern world at large enhancing their responsibility in acquiring and exploiting knowledge in practice. The authors argue that future translators and interpreters are more stimulated to learn technical terminology in the digital environment through subject-oriented terminology courses on the basis of e-technologies. In this study, the mixed research design was based on quantitative (experiment, measuring variables, finding frequencies, hypothesis testing) and qualitative methods (analysis of the data collected, monographic methodto interpret the results obtained in a coherent logical perspective). The experiment, conducted by the authors, engaged the fourth-year students of the National Technical University of Ukraine "Igor Sikorsky Kyiv Polytechnic Institute" (after this, officially abbreviated name -Igor Sikorsky KPI), majoring in translating and interpreting. To carry out the pedagogical experiment, the subsystem of exercises for forming terminological competence in bilateral interpreting in Moodle-based e-learning course was developed in collaboration between the educators from Kütahya Dumlupinar University (School of Foreign Languages) and Igor Sikorsky KPI (Department of Theory, Practice and Translation of the English Language). The proposed subsystem of exercises was supposed to: meet the ultimate goals of forming terminological competence; gradually contribute to acquiring knowledge and skills, which determined the three-stage training process; have a unified structure; have a built-in assessment system; provide students with self-test capability when performing the exercises. It is noted that the opportunity to do the designed course from any convenient device (smartphone, tablet, laptop, PC) makes it easily approachable, and helps students improve the skills of autonomous learning and self-monitoring.

The article highlights exploiting modeling in the interdisciplinary educational process at a modern technical university in Ukraine. The focus of the study is to consider the interdisciplinary approach to modeling in teaching English for Specific Purposes (ESP) to develop technical students' strategic competence as the cognitive ability to intervene in solving various problems. The methodology involves the complex of complementary methods: analysis of psychological and pedagogical sources on the issue under study; the observation of the educational process, and monographic practice (interpreting the results obtained in a coherent, logical perspective); generalization and systematization of the collaboration between the Faculty of Chemical Engineering and the Faculty of Linguistics of the National Technical University of Ukraine "Igor Sikorsky Kyiv Polytechnic Institute" (after this officially abbreviated name – Igor Sikorsky KPI) on implementing the model of interdisciplinary interaction to develop students' strategic competence through producing secondary sci-tech texts in the course of preparing their qualifying papers. The suggested interdisciplinary model covers three stages of realization: initial stage (activates knowledge in the subject area transferred to the foreign language environment), cognitive-communicative stage (activates the cognitive processes to develop the levels of thinking within the framework of Bloom's taxonomy), and communicative-productive stage (develops communicative strategies for writing abstracts of patent documents in English).
