The aim of the paper is to state the possibilities and roles of media statements on the relations between Russians and Czechs during intercultural cooperation in the field of inbound tourism in the Czech Republic. The paper expands and complements the conclusions of the research of the co-author's dissertation. These became the theoretical basis for a contribution to the discussion of whether the media can contribute to a higher level of relations between the nations and possibly remove the different expectations of both Russians and Czechs in the provision of services and their use in inbound tourism.

As cold-formed steel profiles are increasingly used for load-bearing structural systems, their fire design requires specific attention due to their thin-walled nature and high slenderness. In some specific applications such as in storage hall floor systems, these structures are used without sheathing or thermal protection on the fire-exposed side. Yet, there is a lack of data from fire resistance tests on full-scale load-bearing thin-walled steel structures, especially with directly exposed steel. This article describes two standard fire resistance tests on full-scale light gauge steel frame floors made of cold-formed steel lipped channel girders and joists topped by chipboard panels. The experimental program was designed to investigate the fire resistance of the unprotected girders. A specificity of this program was that the girders were subjected to a low load level to probe the ability to achieve without passive fire protection a 30-min fire resistance rating typical for storage hall structures in the Czech Republic. The absence of protection resulted in differences in thermal gradients and bracing compared to common fire tests, as well as a very low degree of utilization leading to an expected failure temperature higher than 800 °C. The results showed that the two floors remained stable during the 30 min with limited deflections, but failed the deflection rate criteria after 24 and 22 min, respectively. Comparison is provided with the calculation methods from the Eurocodes. The presented results provide new data on the response of full-scale, unprotected cold-formed steel floor systems subjected to fire, which can be used to calibrate numerical models and fire design methods outside of the range currently covered by the codes. • Fire design of thin-walled steel structures requires specific attention. • Lack of data from fire resistance tests on full-scale thin-walled steel structures. • Some thin-walled structures are designed without the use of passive fire protection. • Calculation methods show good agreement with test data in temperature predictions. • The test results can be used to calibrate numerical models and fire design methods.
