Abstract Efficient allocation of available means presuppose detailed knowledge about risks, costs and benefits within the area of interest. The societal demand for increased safety of hydraulic structures, as components of the critical infrastructure, requires considerable investment. To evaluate the effectiveness of potential measures in an environment influenced by epistemic and aleatory uncertainties, risk analysis and cost-benefit analysis are used in practice. The above described approach is now fully implemented when considering natural floods and structural flood protection measures, and also presented in the paper. For potential failures of dams and other important hydraulic structures however the procedure becomes rather more complex to comprehend the effect of designed measures on different failure modes. After introducing governing theoretical principles used for the natural flood vs structural measures analysis, the paper presents examples of application of combination of cost-benefit and risk analysis in the framework of the authors’ work as Strategic Expert of the Ministry of Agriculture of the Czech Republic for the different stages of the flood prevention program. The last part of the paper focuses on dam safety and the application of risk analysis as a support tool for decision making processes. It describes the practice applied in the Czech Republic and comments on the advantages and disadvantages of the current approach while suggesting further possible improvement.

Nuclear energy accounts for a significant part of the total energy production in the Czech Republic, which is currently facing a problem dealing with the high-level radioactive waste (HLW) and the spent nuclear fuel (SNF). Deep repository is the safest option for storage of HLW. Rock environment of the area must guarantee the stability of the deep geological repository for at least 100,000 years. The aim of the research is a long-term evaluation of the climatic changes of the hypothetical area of interest, which corresponds to the candidate sites for deep geological repository in the Czech Republic. The occurrences of endogenous and exogenous phenomena, which could affect site stability, were evaluated. Concerning exogenous processes, research focuses mainly on the assessment of climatic effects. The climate scenarios for the Central Europe were examined – global climate change, glaciation, and the depth of permafrost as well as CO2 increase.

As our world becomes increasingly complex over time, we are using increasingly sophisticated tools to be fed and entertained. This increasing complexity has both advantages and disadvantages. Our dependence on electric power is almost absolute and a long-term blackout could become potentially fatal to any region or country hit by it. It has been a rule of life that the intensive preparation to some crisis begins not sooner than after it strikes and causes a big damage. Prague city management did not want to wait to find out, however, and organized an exercise to understand just what such a situation might look like and just how well prepared the capital of the Czech Republic was to manage it. The exercise was designed, run and documented by up-to-date information technology, enabling further study and analysis of results to improve the city’s resilience and to prepare adequate means for mitigating potential damage.

Background: Thrombophilic mutations in genes for factor V Leiden and factor II prothrombin are among the most important risk factors for developing the thromboembolic disease (TED), along with the use of oral contraceptives (OCs) or smoking. Aim: This study aimed to investigate the occurrence of risk factors in young women using droplet digital PCR (ddPCR) and, based on the results of this investigation, to perform a cost–benefit analysis of ddPCR-based screening in young women starting to take OCs compared to the treatment costs of patients who develop preventable TED in the Czech Republic. Methods: In this cross-sectional study, female university students filled in a questionnaire and provided a blood sample for DNA isolation and ddPCR analysis of both aforementioned genetic risk factors. The results, along with data from literature and web search, were used for cost–benefit analysis valid for the Czech Republic. Results: Out of 148 participants, 30 (20%) were smokers and 49 (33%) took OCs. A mutation was confirmed in 6 women (4.1%) in the factor V gene and in 3 women (2%) in the factor II gene, respectively. A model calculation on a cohort of 50,000 women starting to use contraceptives in the Czech Republic every year showed that at maximum compliance, (i.e., non-use of OC and smoking cessation), screening could prevent 68 cases of TED over the course of the mean period of OC use (5.7 years). Economically, the costs of testing in this cohort (2.25 mil. USD) would be significantly lower than prevented treatment costs (16 mil. USD at maximum compliance); the cost–benefit break-even point would be at 14.1% compliance. Conclusion: The cost–benefit analysis based on our results indicates that screening for factor V Leiden and factor II prothrombin in young women before starting to use OCs would, in the conditions of the Czech Republic, likely be highly economically effective.

<p><strong>Abstract.</strong> The article presents conclusions of a comprehensive analysis of pilot data collection using four mapping methods. To validate mapping methods and procedures, we selected three ten-kilometer sections of the first class roads with different geomorphological, vegetative and transportation properties. All sections were measured by aerial photogrammetry using GSD<span class="thinspace"></span>=<span class="thinspace"></span>4<span class="thinspace"></span>cm, mobile laser scanning equipment linked with cameras, by geodetic surveying methods, and one section was also measured by UAV. The tested methods mapped selected features of vertical and horizontal traffic markings on the first class roads. The traffic marking measuring sets were analyzed from the perspectives of personnel, time, data, costs, and technological and organizational aspects. All the mapping methods were verified as mentioned above starting from work preparation phase, its terrain realization, captured data processing and detailed analysis, concluding with stating the advantages and disadvantages for each mapping method. One of the analysis outputs was proposals to change and refine road administrator’s regulations. The mapping methods were compared with geodetic measurements.

The Impact

This paper analyses the impact of the common European criteria on the Less Favoured Areas (LFA) delineation in the Czech Republic (CR) and compares it with currently used point evaluation system. Further, it compares the advantages and disadvantages of both delineation systems from various points of view and concerning the needs of common agricultural policies. In the Czech Republic, a system of point evaluation of the agricultural land productivity based on the Evaluated soil-ecological units (ESEU) is used for delineation of the other than mountain LFA since 2001. Within the programme period 2014–2020, the European Commission proposes to delineate the other than mountain LFA using a single set of criteria, common for all the member states. Some criteria of the natural handicap proposed by the European Commission (EC) can be derived directly from the ESEU five-cipher code and from the soil maps. The comparison clearly shows that the current Czech system of point evaluation of the productivity of agricultural land can express better the influence of worse soil and climatic conditions on the limitations of the agricultural use of the land than the system proposed by the EC. Additionally, the ESEU point evaluation can express also the effect of simultaneous influence of more factors, which may thus increase or decrease the final ESEU point values. Conversely, it is necessary to remark that the land quality evaluation based on ESEU is rather complicated and not easily understandable for the wide public. Also, it cannot be applied in all the EU countries.

This chapter revisits an earlier published model of the Cost-Benefit Analysis method focused on KM projects. Although it continues to centre on the customer and the general market environment as knowledge sources used to evaluate the appropriateness of a Knowledge Management (KM) project, it expands the discussion to incorporate the latest research on this topic. In addition, the tangible and intangible benefits of a successful KM deployment continue to be stressed; it highlights the various barriers and sets recommendations that may be pursued. Given the on-going nature of this condition in the Czech Republic, the authors continue to pursue an active research protocol.
