Introduction. Medical conferences are a key source of new and relevant knowledge for practicing physicians. Physicians use social media to share this knowledge with their colleagues. As a result, there is a lot of discussion on social media about the topics covered in the scientific presentations. This initiative has some educational value, which is being actively explored. The discussions around such posts make ideas, insights, opinions and experiences of peer-colleagues easily available. They also immediately raise awareness of new clinical research and scientific data.Objective. We studied how often Russian physicians use available social networks (vrachirf.ru, doktornarabote.ru. vk.com) to share information from scientific conferences with their colleagues.Materials and мethods. We searched for posts using keywords related to medical conferences and selected among the search results the entries whose authors, as physicians, disclosed selected elements of the content of scientific presentations.Results. We identified 65 entries over the past 4–12 months where physicians shared facts and ideas presented at scientific conferences. Entries posted on professional physicians’ social networks with access restricted to lay public generated vigorous meaningful discussions, unlike posts on the mainstream social network vk.com.Conclusions. Doctors very rarely share on social media the facts and ideas presented at Russian scientific medical conferences. Physicians demonstrate significant interest in these posts and actively discuss them. Further study should reveal the educational potential of the described phenomenon and suggest the pathways to its effective utilization.

BACKGROUND: Physicians who attend international conferences cover their content on social media. Such posts generate an active response and discussion in the comments involving other physicians. Attending all conferences when they are held simultaneously is impossible; therefore, brief communications that capture the essence of a missed presentation are in demand, generate an immediate response, and quickly raise awareness of new clinical research and scientific data. This phenomenon was not studied in Russia. However, the posts were analyzed and the activity and interest among Russian physicians were evident. AIM: To investigate how frequently Russian physicians use available social networks to share information from scientific conferences with their colleagues. METHODS: The search for posts for the last 412 months in Russian social networks such as VKontakte (vk.com), VrachiRF (vrachirf.ru), and Doctor na rabote (doktornarabote.ru) by report, conference, congress, symposium, and medical conference keywords was conducted. The selected recordings were classified into 6 categories (conference announcements; reports of past conferences without disclosing the content; professional journalistic reports, disclosing the content; reports from physicians, disclosing the content; videos of reports with disclosure; videos of reports without disclosure) and counted (1373 posts in total). However, the category Reports from physicians revealing the content of some selected parts of the report and facts and ideas presented in the report was given special attention due to useful information from the conferences and a reason to discuss in the comments. In addition, relevant studies by authors from other countries were analyzed and compared with our results. RESULTS: A total of 1,373 posts (searched by keywords), of which 65 were in the category Reports from physicians revealing the content of some selected parts of the report and facts and ideas presented in the report was reviewed. The number of such posts is limited; however, this information is of interest to physicians (high number of views and dozens of comments). By comparison, the number of such messages in other countries may reach into the hundreds at a single conference alone. Based on foreign experience, the discussion of the reports on social networks helps both to spread new knowledge and facilitate joint learning and interaction among physicians, which contributes to the generation of useful material that passed peer review. Possible reasons for the low number of such posts on Russian social networks are as follows: mostly messages and discussions take place on professional social networks (VrachiRF and Doctor na rabote), foreign organizers actively encourage participants to use social networks with conference hashtags, and the multimillion-speaking English-speaking audience encourages authors to write more posts with their feedback. CONCLUSIONS: Physicians quite rarely share facts presented at Russian scientific medical conferences on Russian social networks. However, users of social networks show considerable interest and actively discuss such posts. The study of this phenomenon will enable the assessment and effective use of its educational potential.

В рамках волновой теории сейсмостойкости разработана методика по определению сейсмических ускоре-ний в плотинах из грунтовых материалов. При этом учитываются влияние основания и излучение в него сейсмиче-ских волн. Методика основана на численном решении динамической задачи методом конечных разностей. На основе разработанной методики составлена компьютерная программа SGD «Определение сейсмических ускорений в пло-тине из грунтовых материалов», которая позволяет найти значения ординат расчетных эпюр ускорений по высоте плотины для всех моментов времени. В результате можно получить наиболее опасные эпюры ускорений при прямом и обратном сейсмических воздействиях. Приведена верификация (проверка соответствия) расчетных и наблюденных сейсмических ускорений для каменно-земляной плотины Днестровской ГЭС-1. Наблюденные сейсмические ускоре-ния получены при проведении экспериментальных взрывов, расчетные сейсмические ускорения -в соответствии с предложенной методикой определения сейсмических ускорений в плотинах из грунтовых материалов. Сравнитель-ный анализ результатов расчетов с данными натурных наблюдений показал, что максимальное отличие экстремаль-ных ускорений, полученных расчетным путем и при проведении натурных наблюдений, не превышает 10,11 % для гребня плотины и 6,56 % для ее подошвы. Результаты исследований позволяют рекомендовать разработанную программу для выполнения инженерных расчетов сейсмических ускорений в плотинах из грунтовых материалов. Применение программы даст возможность определять сейсмические ускорения в плотинах из грунтовых материалов с достаточной степенью достоверности. Abstract. A methodology for determination of seismic accelerations in earth dams has been developed within the framework of seismic resistance wave theory. In this case we take into account an influence of the dam foundation and seismic wave emission into it. The methodology is based on numerical solution of the dynamic problem while using a finite difference method. A software program SGD "Determination of seismic acceleration in the earth dam" has been prepared on the basis of the developed methodology. The program allows to evaluate ordinates of calculation orthographic representations for acceleration throughout the dam height for all time moments. Thus, it is possible to obtain the most dangerous acceleration orthographic representations at direct and reverse seismic actions. The papers presents verification (compliance test) of calculated and observed seismic accelerations for the rock-fill dam of the Dnestrovskaya Hydro-Electric Power Plant No 1.
