The designs of turbo roundabouts vary among countries and undesirable and potentially dangerous situations can occur for vehicles passing through the roundabout. In this article, we focus on an analysis of one of the problems within sustainable road transportation, i.e., the geometric layout of turbo roundabouts. First, we review the Czech and foreign regulations and describe the design procedures for turbo roundabouts. Studies that have been performed in the Czech Republic and abroad (the Netherlands, Slovenia, Poland, Germany, Hungary, etc.) are described. We evaluate the geometric layout of turbo roundabouts, the effectiveness of construction adjustments at the entrance to the roundabout, and an analysis of the physical separation of lanes. We present procedures and methods for measurements and assessments, which are used for evaluating the effectiveness of the geometry of a turbo roundabout. Finally, conclusions for the given hypotheses are given, as well as the importance of geometric elements (shape of the turbo roundabout, physical separation of lanes, the spike, etc.) for the actual passage of vehicles through the turbo roundabout. Furthermore, we discuss how these elements influence the safety of road traffic, the sustainability of road transportation, and the emergence of potentially dangerous situations.

This article focuses on the experience of Czech customers with the purchase of products labelled by the Association of Regional Brands and Bohemian Paradise Association. The aim of this paper is to evaluate selected indicators associated with purchasing certified regional products. The studied characteristics focus on the knowledge and perception of several chosen microregional brands and on the purchase of a certified product itself. The article presents the results of research conducted through a questionnaire survey, whose 1390 respondents are residents as well as visitors of eight different micro‑regions in the Czech Republic. Awareness of regional brands within the sample surveyed is around 46 %. The relationship between awareness of regional brand and respondents’ age, education and status towards the region has been identified. The perception of consumers considered, a brand is most often associated with tangible products, namely food and agricultural produce. Consumers view brands chiefly as a guarantee of production in the given region and a certain tradition. Most often, the respondents take notice of brands on the packaging of a particular certified product.

Abstract The article’s aim is to compare the opposite processes of social exclusion and inclusion in South Africa and in the Czech Republic, in the past and at the present time. Even though these societies differ culturally and geographically, the comparison of some important factors, which are causing the exclusion of some people groups, might be interesting. In both cases we will closely follow the social, ethnic and racial groups, which are mostly excluded in the given environment. In South Africa it concerns Black and Coloured Africans, and in the Czech Republic the Roma ethnic minority group, the only ethnic group which is to a high extent excluded. In the history of these two countries we can find a similar historic aspect, both of them had experienced totalitarian regimes. Today, with the benefit of more twenty years, we can see the changes, which both these countries have undergone, and observe as well how these changes influenced the processes of inclusion and exclusion of the given social, racial and ethnic groups.

Postmortem computer tomography (CT) came into practice of forensic medicine in the 1990s and has later been complemented with magnetic resonance imaging (MRI). A pioneer virtual autopsy was conducted in Germany in 1983. In the Czech Republic, this examination was first performed in 1993.A typical examination requires about 30 min, with the most resource-demanding stage being the image data rendering. CT was shown to better capture skeletal structures, while MRI contrasting is superior in terms of visualising soft tissues. In the Czech Republic, CT-based virtopsy is legislated mandatory to document deaths inflicted by gunshots, road traffic and aviation accidents, high falls, occupational and explosive-related injuries, thermal and mechanical traumas, strangulation, drowning as well as to examine unidentified or decomposing bodies, deceased children and adolescents aged under 18.CT scanning prior to conventional autopsy provides a forensic expert with guidance to reveal pathologies non-invasively in particular regions that are difficult to dissect or access. The advantage of virtopsy is the objective acquisition of data that can be re-examined, reinterpreted or juxtaposed with the results of conventional autopsy and easily recovered for possible further expertise.

The aim of the article is to make a comparison of brownfields in the South Moravian, Olomouc, Zlín and Moravian-Silesian regions based on the spatial standpoint. Data on brownfields were obtained through the National Database of Brownfields, which is managed by the CzechInvest agency. Information about these abandoned buildings and grounds were dated on 31st March 2021. The finding of the contribution is the fact that the most abandoned buildings and areas are mainly in Moravian-Silesian and South Moravian Region. Most of brownfields are after industrial activities, civic amenities and agricultural activities. In the given article, the analysis of brownfields according to individual indicators was performed on the basis of spatial and geographical point of view. It was found that most of the examined abandoned buildings and areas are located mainly in cities, which were followed by municipalities. Furthermore, it was proved that the size of brownfields from 54% is in area up to 1 (ha). The following indicator was the distance of abandoned buildings and areas from the centre of the cadastral area. Based on the results, it was found that 45% of the analysed brownfields are located 1-3 km from the centre of the cadastral area.

A cursory look at different examples of activist and community-based performances in Singapore, Colombia, and more detailed analyses of two recent participatory theatre productions in the Czech Republic and the Netherlands reveal that models that distinguish community art from avantgarde art in the East and the West resist categorization.

Experts in the blacksmithing of Ancient Russia have long been interested in iron household items with cutlers’ marks, such as knives and scissors. The research literature has already reviewed similar findings from Moscow, Tver, Torzhok, Pskov, Smolensk and Izborsk. In this study for the first time assembled, described and dated all iron knives and scissors with cutlers’ marks identified in the archaeological collection of Veliky Novgorod. All cutlers marks have been analyzed, and almost all have analogies in medieval Western European material. Almost all types of cutlers’ marks that are represented on Novgorod items are found on knives, and sometimes on swords or falchions found on the territory of Poland, the Czech Republic, Germany, Italy, the Netherlands and England. There are similar cutlers’ marks on the territory of Ancient Russia, but in much smaller numbers. All items marked with the cutlers’ marks are products of Western European production, the old Russian blacksmiths did not practice branding their products. Most items with cutlers’ marks were brought to Novgorod from Poland, the Czech Republic and Germany. Individual items could get to Novgorod and from England through Hanseatic merchants. Items with cutlers’ marks found during excavations in Veliky Novgorod date back to the 13th – first half of 15th centuries.

The article’s objective, which is to identify the causes of the very poor level of management of the administration of these state assets, to present the possibilities of a long-tested experimental model at the Land Fund of the Czech Republic, and to draw attention to this model’s potential in its possible implementation in administration of the entire management complex of these state assets in the Czech Republic. The authors first dealt with the theoretical aspects of the given issue, and then prepared an analysis of the original debt collection management “system”. This is logically followed by an analysis of the experimental model’s efficiency, rounded off with its conclusions. The final chapter contains the results of the research aimed at the current level of knowledge of the examined issue in compressed form, further the outcomes of the research concerned with original unsystematic debt collection management, also results of the implementation of the experimental model, and the assessment of the significance belonging to the results of implementing the experimental model for the entire national economy of the Czech Republic.

AbstractThe first biocorridors were established in the territory of the Czech Republic in the 1990s. One of them, planted on a former agricultural land, was the Radějov biocorridor. This paper deals with the growth and development of trees and shrubs on three permanent research plots in 1993 - 2012. Repeated inventories of trees as well as monitoring of their biometrical parameters were carried out in both tree and shrub layers. The number of trees decreases with the increasing level of stand canopy. Moreover, mean heights, diameters and crown projection areas of selected woody plants were compared. Under the given conditions, the growth of these woody plants can be positively evaluated.
