The focus of this paper is the characteristics of bioclimatological conditions of one popular touristic region in Czech Republic. Biometeorological conditions of the region were described from the point of view of energy exchange between human body and atmospheric environment. Influences of meteorological agents on human organisms are presented by using two indices based on MENEX model. Indices illustrate the physiological strain and subjective thermal feeling of a person exposed to thermal environment. Obtained values of indices were compared to synoptical weather types. Comparisons were provided for the most uncomfortable conditions. Groups of synoptical weather types that occur when biometeorological conditions are very uncomfortable were found.

The contribution “Anti-state Crimes in Modern Codifications” deals with the topic of anti-state crimes during centuries. Firstly, legal concepts in the pre-state period are mentioned. Then the attention is paid on the evolution of this institute in the Euro-Atlantic area. From this point of view, there are mentioned mainly regulations from England (1351), France (1810), Germany (1871) and Soviet Union (1958) which could be remarked as the most important for the development of other countries. On the other hand, it also reminds the development of codifications in Czechoslovakia, the Czech Republic and Slovakia, which were affected by the Austro-Hungarian legislations as well as German and Soviet approaches. The Czech current arrangement generally does not depart from the other European samples, but it cannot be omitted that in the Czech Republic it is distinguished the penal concept of the high treason (Landesverrat, vlastizrada) from the constitutional concept (Hochverrat, velezrada) which is dedicated to the presidential anti-state activities. The contribution also indicates that the concept of anti-state crimes in countries has not been unified and it has been varying according to various experiences and attitudes.

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.

The situation on the electricity retail market in the Czech Republic is not clear because of the number of suppliers and its products. Although the information about the prices for the electricity consumption for households is available on the web and each household can change the supplier nearly with no extra effort and cost, households are still often not familiar with the individual price items of the products. In this article the analysis of the Czech electricity market from the distribution rate D25d point of view is made for the years 2017-2018 when the household annual consumption is simulated via Monte Carlo simulation model. The aim of this paper is to select such a supplier and product that minimizes the total costs of the electricity for a household for the selected distribution rate and compare it with the results from the previous years.

Abstract In 2015–2016, 6,429 km medium-voltage power lines with 76,430 pylons were checked for bird mortality in the Czech Republic. 1,326 bird victims of power lines were found, 156 of which died after collisions, and 1,170 birds were electrocuted. They belonged to 60 species from 12 orders, and birds of prey made up almost half of all victims. Steel pylons bearing several cross-arms including upper and crosswise jumpers were identified as most dangerous from the electrocution point of view. On the other hand, pylons in straight lines with Pařát cross-arms (triangular arrangement of conductors without any horizontal bar) were among the least dangerous, and when they had a simple perch fitted below the cross-arm, no mortality was recorded. But these pylons are new in practice and despite becoming widely used recently, they form less than one tenth of all pylons in the Czech Republic. On other pylons various types of mitigation measures have been installed. Commonly used plastic covers and plastic strips have proved to be especially effective, but only in cases when they are undamaged and correctly installed.

The Czech Republic

The generation of recyclables in the Czech Republic has long been under the European average, but the proportion from municipal waste as a whole has been growing over the past few years. Previous research in the Czech Republic mainly focused on organizational or situational factors explaining recycling performance in municipalities. This study focuses on individual characteristics that are connected, among other things, to ongoing demographic changes. Currently ongoing sociodemographic development in the Czech Republic, as well as other developed countries, influence a broad range of aspects of social life, including waste generation and its structure. This paper aims at quantifying the relation between the sociodemographic characteristics of municipality inhabitants and recyclable generation. For this purpose, 13 variables describing inhabitants, households, and housing in 4897 Czech municipalities were selected that could influence the generation of recyclables according to foreign studies. Data were analyzed using multidimensional linear regression. Even though the resulting model only explains 9%, it is statistically significant and implies that sociodemographic variables can help explain recyclable generation. From this point of view, important variables are average household size, share of tertiary educated people, share of family houses, purchasing power per person, percentage of people employed in agriculture, and sex ratio. To increase the explained variability and emphasize local differences in recyclable generation, we also used geographically weighted regression (GWR). GWR results show that, to understand waste generation (at least in the Czech Republic) on a municipal level, it is necessary to also consider spatial effects and regional specifics.

The Impact

Purpose. The aim of this study is: (1) to compare the features of ski resorts in Poland, the Czech Republic and Slovakia in relation to the prices of ski passes, (2) to indicate the best ski resorts in these countries in terms of value for money - the ratio of offered quality to the price of ski passes, (3) to compare of differences in value for money (e.g. offered quality compared to the price of a ski pass) in these countries. Method. Data for analysis were features of quality and prices of one-day ski passes for 245 ski resorts in Poland, the Czech Republic and Slovakia. The data was obtained from the websites of the surveyed ski resorts and web pages: skiinfo.pl, holidayinfo.cz and holidayinfo.sk. The quality index of ski resorts was constructed using Principal Component Analysis of the seventeen quality features regarding the studied resorts. The comparison of ski resorts was conducted using the Free Disposable Hull analysis. Differences in the level of quality of the resorts' and ski pass prices were calculated using the Kruskal-Wallis H nonparametric test. Findings. Eleven features of the eighteen surveyed locations were differentiated between surveyed countries (including the price of the ski pass: Polish ski passes are the most expensive and the cheapest are in Slovakia). The FDH analysis revealed the existence of eight effective – from the skiers' point of view – ski resorts, i.e. those that offer the given quality at the lowest price (value for money). Polish ski resorts are characterized by significantly higher quality than Czech or Slovak resorts. Research and conclusion limitations. The analysis did not take the impact that congestion and queues to lifts, prices of accommodation, restaurants and nightlife in the resort (except night skiing) might have had on the skiers decision into account. The results may also be influenced by the method of quality index construction. Practical implications. The results of FDH analysis enable the identification of inefficient ski resorts in the analysed countries and indication of the differences existing in terms of quality between ski resorts. The conclusions allow to select the most efficient ski resorts which can be helpful in the design of tourist offers and it may also indicate the need for adjustments in prices of ski passes at some ski resorts. Originality. No comparative analyses of Polish, Czech and Slovak ski resorts were found in the literature to date. Type of paper. The article presents the results of empirical research.

A number of authors deal with problems of convergence, divergence and disparities, particularly with reference to economic growth and its comparison in groups of countries. This paper is aimed at problems of using basic methods of measuring the convergence at the evaluation of the development of selected demographic characteristics of particular regions of the Czech Republic for the period 1992 to 2007. From demographic data provided by the Czech Statistical Office some indicators were selected associated with aging the CR population. In particular, following indicators were used: the proportion of productive population, coefficient of loading the productive population by young persons, coefficient of loading the productive population by old persons, coefficient of the total loading and index of age. A precondition served as a working hypothesis that in addition to the negative demographic development affecting the CR as a whole, the convergence of its particular regions also occurred, viz. regions at the level of NUTS 3. At the quantification of convergence processes in particular regions of the CR, the method of beta convergence was used (in a simplified linearized form) as well as the method of sigma convergence. Both methods predicate unambiguously on the convergence of the CR regions from the point of view of all examined demographic indicators. From the aspect of both methods, the fastest convergence occurred in the studied period in the indicator of loading the productive population by old persons. In this indicator (as the only from monitored ones), no disparity showed as well, ie a region showing an isolated development was not noted. Opposite situation manifested itself at the indicator of loading the productive population by young persons. Only elimination of the capital city of Prague reversed an original result showing evidence of the divergence of regions from the aspect of this indicator. Disparities of the capital city of Prague occurred even at other two indicators. Only from the aspect of age, the Central Bohemian region became a region being beside the general trend of convergence.

Time Of Collection

In this study, we present faunistic data about spiders in selected sinkholes of northern part of Moravský kras Protected Landscape Area. Time of collection was established in the following terms: 24 March 2010 – 22 September 2010. We collected altogether 5742 adult specimens which were determined to 59 species of 14 families. We found two very rare spiders (critically endangered Porrhomma errans and endangered Walckenaeria monoceros) and several interesting, rarely collected bioindicator species (Alopecosa trabalis, Mecopisthes silus, Zelotes longipes). From the bioindicative evaluation point of view, 44% of found species belong to species with connection to natural habitats, 37% belong to species preferring semi-natural habitats, and 19% belong to species of disturbed habitats. From the relictness point of view, majority of species was of the expansive category (53%), 40% of class II relicts, and only 7% of class I relicts. Sink holes did not increase total biodiversity of agricultural land too much because of their relative small size.
