The article presents results of research in the field of prototyping -3D printing. The authors are focused on polylactic acid material known by the abbreviation PLA, which is widely used in 3D printing method to produce objects. The tech-nology of successive layering of plastics and its solidification causes states of tension in printed objects and subsequently their deformation. That may even lead to torn the object from the print pad. The article deals with dimensions of the deformations at the specimen just in dependence on heating of the print pad. The authors also suggest a compromise solution between excessive deformation of underlying layers and therefore proportional change of physical dimensions of the object and low adhesion of the object to the underlying heating bed, which can be seen as cut off the object during the printing process as mentioned.

Every nation has its unique intangible culture that is passed down from generation to generation thanks to what is still alive. Czechia has a rich intangible cultural heritage, e.g., Mardi Gras, Verbuňk dance, blueprints, Christmas-themed beaded decorations, puppetry, etc., which are all on UNESCO’s Intangible Cultural Heritage Lists. However, it also has other traditions, ceremonies, legends, folk tales, and weather lore related to weather forecasting in relation to agriculture. The most popular weather lore is related to the feasts of saints, as the feast’s dates have remained unchanged for a very long time in the calendar. The aim of this study is to bring Czech weather lore, which, even today, in the age of numerical models, has a certain meaning, closer to readers. Some weather lore has been forgotten over time, but most of it still remains in Czech folk traditions, which continue to be spread orally or in written form. We wondered whether young people knew weather lore as part of their cultural heritage. The results of a survey based on a sample of 220 respondents, including students at the University of West Bohemia in Pilsen and future teachers at primary schools, led to the conclusion that weather lore is well-known among the young Czech generation as well.

This paper aims to examine preservice teachers' views of the School of Pedagogical and Technological Education (ASPAITE) regarding the skills of online teachers-counselors and the effectiveness of distance education during the pandemic of COVID-19. The aim of the conducted study is related to a continuous effort of research so as to ameliorate potential teachers' effectiveness in distance education. Firstly, attention will be drawn to the concept-key term of distance education, and afterwards, we are going to proceed into an extensive presentation of its basic principles and characteristics: active teaching, leadership and management, active learning of students and technological abilities. The results of the conducted research show that the role of teacher/counselor in distance education is a multiple one, as he or she must utilize and apply not only formal and informal qualifications as used in conventional education but also additional ones that bridge the gap of physical absence.
