Human activities, population growth and settlements pose a threat of degradation for the natural environment and especially for karst water [1, 2]. Water is a key factor in the formation and occurrence of karst phenomena. A number of surface watercourses flow to the karst areas from the non-protected areas. These watercourses almost instantly disappear into the underground at the geological boundary of the karst area. The hydrological regime of these watercourses in the karst area is very complicated. Underground spaces are collectors gathering water from surface flows. These ground waters have limited filtration and self-cleaning capability that can result in rapid transmission of the potential contamination and subsequently threat to drinking water sources. Human

The prevalence of inequalities in the general health position of communities can be assessed by using selected determinants. The aims of this article are three-fold: (1) to apply a comprehensive approach to the assessment of inequalities in the general health position of communities, (2) to determine the spatial differentiation of determinants, and (3) to present selected assessment methods and their impact on the results. To present a quantitative assessment of these inequalities in health status in communities, a composite indicator (Health Index) was developed. This Health Index is composed of 8 areas of evaluation and 60 indicators which include, amongst others, determinants of health status and healthcare at district level (LAU 1) in the Czech Republic. The data are evaluated using multicriteria decision-making methods (the WSA and TOPSIS methods). Findings suggest that, when all eight domains are assigned the same weight of one, the spatial differentiation among the districts is similar when using both methods. If different weightings are assigned to the districts, changes occur in both the index values and the rankings of the analyzed districts. For example, the allocation of weightings in both methods results in a rearrangement of the ranking of districts for which the Health Index is around the average.

The presented paper deals with the regionalization of the electoral support of the Czech Pirate Party (Pirates) in regional elections using methods and techniques of spatial data analysis. The aim is to answer the question whether the territorial distribution of Pirate electoral support allows this party to participate in governance at the regional level and thus influence the form of regional policy in individual regions. The results of the analysis show that the spatial distribution of Pirates’ electoral support in regional elections differed quite significantly not only from the pattern found in the elections to the Chamber of Deputies of the Czech Parliament and elections to the European Parliament, but also between individual regional elections. This suggests the current lack of anchorage of Pirates’ electoral support in regional politics, but at the same time, it may have its origins in the second-order character of regional elections and the candidacy of many local and regional entities in regional elections. On the other hand, the results of the regional elections in 2020 meant that the Pirates received seats in all regional councils, but especially in nine of the thirteen regions they joined the regional government (similarly to two years earlier when they joined government of capital city of Prague), gaining the opportunity to influence, with regard to its priorities, the form of regional governance in most Czech regions.

AbstractŠEVELOVÁ, L., KOZUMPLÍKOVÁ, A.: The numerical model for parametric studies of forest haul roads pavements. Acta univ. agric. et silvic. Mendel. Brun., 2010, LVIII, No. 5, pp. 361-368 Forest roads pavement structures are considered to be low volume roads. These roads serve as a mean of transport of wood and people. Besides they are currently o en used for recreational purpose.The construction of the pavements should be suitable for forest transportation irrespective of their low bearing capacity. These pavement structures are very specifi c for special unbound materials that are used in their construction. To meet the requirements of the pavement designs and simulation analysis the FEM model in the so ware ANSYS was created. This paper compares two material models used for the description of the behaviour of unbound materials. The fi rst is linear elastic according to Hook theory (H model) and the second one is nonlinear plastic model Drucker-Prager (D-P model). ANSYS so ware has been used to create fl exible model based on the parametrers of variable principle. The fl exible model is parametric to realize repeated calculations useful for optimization analysis.parametric study, optimization analysis, FEM, fi nite element method, fi nite element model of pavement, forest pavement roads, construction of pavement roads Specifi ka lesních odvozních cest a jejich význam v lesním hospodářství a zpřístupňování krajiny kladou stále větší důraz na optimalizaci návrhu těchto multifunkčních komunikací. Vozovka, jako vícevrs-tvá konstrukce spolupůsobící s podložím, musí zajišťovat bezpečný a hospodárný provoz motorových vozidel po dobu požadované životnosti při dané intenzitě dopravního zatížení. Stávající klasické ná-vrhové metody pro dimenzování účelových komunikací jsou založeny na znalosti kalifornského poměru únosnosti podloží, označovaného jako CBR (kalifornský index únosnosti podloží (EN 13286-47)), empirii a experimentu. Experimentální měření a zkoušky dodávají sice velmi důležité podklady a informace o vlivu zatížení a klimatických jevů na vozovky, ale jsou podmíněny realizací na skuteč-ných modelech s vysokou fi nanční náročností. Při-tom např. neumožňují analyzovat stav napjatosti konstrukčního systému vozovka -podloží, zachytit efekty přetížení únosnosti, predikovat chování nových materiálů apod.Vhodným a progresivním nástrojem pro analýzu těchto problémů jsou parametrické studie a spolehlivostní analýzy (Florian, 2005), které umožňují vyšetřovat vzájemné spolupůsobení jednotlivých částí systému vozovka -podloží, vyčíslit míru vlivu faktorů způsobujících proměnlivost jeho chování nebo zahrnout do výpočtu náhodnou proměnlivost vlastností vstupních charakteristik. Současná geotechnická praxe však nedisponuje vhodným numerickým modelem, který je nedílnou součástí těchto analýz, přestože návrhy konstrukcí jsou při využití numerických metod ekonomičtější (Ravaska, 2002; Gaba a kol., 2002) a poskytují reálnější představu o chování konstrukce.Cílem probíhajících prací je vytvořit vhodný numerický model, jenž ...

The main objectives of the article were: a comparison of the demographic and SE indicators in the South Moravian Region, a study of the development of demographic and SE indicators in the South Moravian Region in the years 2006–2015 and the clustering of similar districts on the basis of demographic and SE indicators as well as mortality and its main causes. The set of aspects affecting the structure of mortality represented 12 demographic factors and 2 socio-economic factors. The results of the composite indicator and the beta convergence indicate that the positive development of the analysed factors was mainly achieved by the Vyškov District and the Brno-Country District, while negative development was observed in the Břeclav District. The cluster analysis was based on four clusters: cluster 1 (Břeclav, Hodonín and Znojmo districts) showed below-average values of the demographic and the socio-economic indicators with a relatively favourable mortality rate based on causes of death; cluster 2 (Blansko and Vyškov districts) was classified as average; cluster 3 (mainly including the Brno-Country District) was seen as the best and cluster 4 (mainly including the Brno-City district) was observed to have negative development.
