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.

Restrictions applied by the government in order to curb the spread of the COVID-19 virus claimed a forced transfer to distance learning in a wide range of school levels, including universities preparing future teachers. The research is focused on school cheating during online testing of future teachers -students of Teacher Training for Kindergartens and Teacher Training for Primary Schools. The questionnaire survey examined a relatively narrow range of possibilities how to cheat -the use of the socalled crib or cheat sheet, also in its electronic form. The aim of the research was to compare the possibilities and approaches to cheating by students during in-class and online examination. Although these are future educators, supposedly having higher moral credit, cheating has occurred and continues to occur even now. A sample of 121 respondents did not confirm a higher rate of use of a prohibited devices in written tests, as expected, but only in online oral exams. The results of the survey within the above mentioned groups of respondents nevertheless seem to have been confirmed to some extent by similar researches, eg. Reedy et al., 2021or Chirumamilla et al. 2020

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.
