This article is devoted to the problem of national and patriotic education of young students by means of digital technologies in the conditions of distance learning environment. It is emphasized that national and patriotic education is a powerful means of strengthening the unity and integrity of Ukraine. It is proved that national and patriotic education will be effective under the condition of systematic and purposeful activity on formation of patriotic consciousness in youth, sense of national dignity, necessity of service of ideals and values of the country. Various forms of educational work of national and patriotic orientation at Pavlo Tychyna Uman State Pedagogical University, which were conducted by digital technologies: online thematic lectures, educational classes, round tables, workshops, guest online meetings with famous researchers of historical heritage of Ukraine, online tours of historical places, virtual exhibitions of art, participation in the national-patriotic student camp "Diia" (Action) and etc. The activity of the University Library and V. O. Sukhomlinsky State Scientific and Pedagogical Library of Ukraine of the National Academy of Pedagogical Sciences of Ukraine, which has a significant impact on the formation of national consciousness and social and political activity of students by modern means of information and communication technologies. It is determined that the project "Inclusive 3D map" helps to broaden the horizons and deepen the knowledge of young students, education of a true citizen, the formation of cognitive interest in the subjects studied, motivation to study, raising awareness of Ukrainians on historical and cultural heritage. The study showed that young students take an active social attitude: they speak Ukrainian, want to live and work in Ukraine, respect their homeland, its traditions, cultural and historical past, love to travel and they are tolerant of people with special needs. Promising areas of educational work with students based on the use of a wide range of information and communication technologies, namely 3D games, TV tandems, podcasts, social networks, video resources in national and patriotic education of youth.

Pellet injectors for EAST and KSTAR tokamaks
Vinyar, Igor,Hu, Jiansheng,Park, Soo-Hwan,Lukin, Alexander,Yao, Xinjia,Li, Changzheng,Chen, Yue,Reznichenko, Pavel,Kim, Hong-Tack Elsevier 2017 Fusion engineering and design Vol.124 No.-
<P><B>Abstract</B></P> <P>The paper presents high frequency pellet injectors developed for edge localized mode mitigation and plasma fuelling of the EAST and KSTAR tokamaks. Each pellet injector is able to inject solid deuterium or hydrogen pellets at steady state mode. Injectors consist of modules including screw extruder cooled by liquid helium and pneumatic punchers for pellet fabrication and acceleration which are optimized to reach maximal injection frequency for specified pellet parameters.</P> <P>The EAST pellet injector is capable of injecting 1.5mm diameter and 1.2–1.8mm length pellets at frequency up to 50Hz with velocities 200–250m/s using two injection modules working in an alternating mode at 25Hz each. Injection reliability over 90% has been confirmed during several cycles of continuous D2 pellet injection at 50Hz. The KSTAR pellet injector has been designed to inject 2mm size pellets at frequency up to 20Hz and velocity 200m/s. Due to improved design of pellet fabrication and acceleration system the world record in continuous injection of 20,164 deuterium pellets (Ø2.0×1.5mm) for 1039s at 20Hz with reliability 97% has been achieved.</P> <P><B>Highlights</B></P> <P> <UL> <LI> 50Hz and 20Hz pellet injectors have been developed for edge localized mode mitigation and steady state plasma fuelling of the EAST and KSTAR tokamaks. </LI> <LI> Innovative pellet fabrication systems have been designed to achieve world record in continuous pellet injection during 1039s at 20Hz with reliability 97%. </LI> <LI> Both pellet injectors have achieved ITER relevant characteristics of plasma fuelling and ELM control. </LI> </UL> </P>
