Every year, there is a decline in the number of car accidents reported in Poland, the Czech Republic, and globally. While recent trends due to the pandemic have influenced these figures, the overall rate remains significant. Therefore, it is crucial to take measures aimed at reducing this number. The primary focus of this article is to analyze the traffic accident statistics for Poland and the Czech Republic. Annual data regarding traffic incidents in both countries has been scrutinized to achieve this. Projections for 2024 to 2030 have been developed based on police reports. Various neural network models were utilized to forecast the number of accidents. The findings indicate that the number of traffic incidents is likely to stabilize. This stabilization can be viewed in the context of the increasing number of vehicles on the roads and the expansion of new highways. Additionally, selecting sample sizes for training, testing, and validation is crucial in influencing the results. Forecasting the number of traffic accidents is important for environmental protection, as accidents can lead to air and water pollution and increase noise, negatively affecting human health and ecosystems.

The article was conceived as an initial insight into the issues related to the representation of individual type costs (e.g. material, labor costs, property depreciation, etc.) in the price of water in the Czech Republic. The aim of the article was to point out the possibility of dependence between the size of the company operating the infrastructural property of water supply and sewerage and the representation of individual costs in the water price within the framework of the case study. As a sample that formed the outputs of the case study, 14 companies were taken, which were selected according to the unified regions of the Czech Republic. Both basic mathematical methods and elementary methods used in financial analysis were used in the analysis. Within the scope of the case study, it can be stated that there is no dependence between the size of the companies and the representation of costs. Among the largest costs from the point of view of financial representation are other direct costs, where the costs of depreciation, property repairs, rental property, as well as wage costs and material costs are mainly represented. Insignificant costs include, for example, energy costs, which are only represented in the range of 1.39–5.70% of the total costs. Therefore, in order for the results included in the case study to be considered statistically relevant, it is necessary to expand the sample and confirm or refute the initial findings published in this article.

The study presents a methodology which can be employed by a wide array of stakeholders in the urban real estate market: policymakers, developers, investors as well as individuals. The methodology is widely applicable globally, and various economic variables can be appropriately linked to its results in order to make the economic implications of the length of permitting processes more transparent and promote affordable housing development and sustainable urban development. Across a unique primary dataset of 189 development projects in Prague, we find significant differences in the time required to obtain permits and to undertake construction work for buildings of different functional types. We attribute these differences primarily to public resistance to certain types of development. Our research also quantifies the percentage increase in construction prices that results from delays in the pre-construction process. We find that residential and mixed-use developments face significantly longer permitting processes than industrial development. This is a surprising finding, as these functions generally don’t give rise to as many externalities, necessitating stricter regulation. In addition, we also find that central locations face longer delays and greater price increases.

The subject of this communication is the evaluation of the results of pedagogical research focused on environmental-technical university education within the framework of a four-year PL-CZ project supported by the EU, entitled "Cooperation between the University of Opole and the University of Hradec Kralove increasing the employability of graduates on the cross-border labour market" and its three-year sustainability, which we have already reported on in a previous communication in this Journal. The aim was to increase the mutual cross-border substitutability of graduates of environmental-technical fields of study of the Faculty of Science and Technology of the University of Opole (PL) and the Faculty of Science of the University of Hradec Kralove (CZ), when looking for employment in Czech and Polish companies. There is an increasing number of graduates of environmental-technical fields of study who do not work in their fields of study, despite the fact that these workers are missing from the labour market in both countries. The convergence of study programs took place in the form of mutual cross-border teaching with the creation of Czech-Polish teaching materials focused on professional terminology and through exchange four-day field trips and fortnightly and monthly curricular internships. A team of internship tutors in companies, future potential employers of students, was created, a questionnaire for evaluating student performance in soft and hard skills was optimised and verified as part of a pilot study. Both groups of PL and CZ students achieved quite comparable results. There are also no significant differences in the evaluation of individual students in soft and hard skills. However, the number of respondents (students) was limited by the financial resources of the PL-CZ project, which were reduced during the COVID pandemic. Only selected students with a strong interest in the field of study and gaining practical experience participated in the study. Therefore, the conclusions of the pilot study need to be verified on a larger sample of respondents.

The serpulid tube worm Laqueoserpula reussi (Weinzettl, 1910), originally introduced as a gastropod named Burtinella(?) reussi, is described from the Upper Cenomanian and Lower Turonian of the Bohemian Cretaceous Basin. It had usually been confused with other species and genera before 2008. Comparison with specimens from the type locality of the type species of the genus Laqueoserpula Lommerzheim, 1979 confirms the affiliation of the Bohemian species to this genus. The simple prismatic (SP) ultrastructure of the tube wall of L. reussiagrees with an assignment to the tribe Serpulini Rafinesque, 1815. In the Upper Cretaceous, representatives of Laqueoserpula are exclusively found in nearshore deposits, where they are accompanied by a high diverse marine invertebrate fauna. By its compact, large and robust tube forming a spiral and extremely thick tube wall, L. reussi was well-adapted to live in nearshore high energy environments, where its tube could be encrusted by bryozoans, brachiopods and oysters, and infested by hydroids and borers.

Ammonites, chiefly from the Upper Turonian Prionocyclus germari Zone, the Lower Coniacian part of the Forresteria (Harleites) petrocoriensis Zone, and the Lower Coniacan Peroniceras (Peroniceras) tridorsatum Zone from the Czech Republic are figured and described, including classic material originally described by Fritsch (1872–1898) and Jahn (1892, 1896). In all, 25 species are recognised, including two, Pseudojacobites sp. and Muniericeras sp., that represent genera previously not known from the area.

Purpose: The objective of this paper is to present Chinese investment flows and the nature of participation, to analyze the differences between host countries, and to identify the determinants of Chinese FDI in Poland and the Czech Republic. Design/methodology/approach: Comparison of the specifics of Chinese direct investments in Poland and the Czech Republic. Findings: The nature of Chinese investment in Europe is changing. After years of being dominated by mergers and acquisitions, Chinese investment in Europe is now more focused on greenfield projects. In 2021, greenfield investments reached €3.3 billion, the highest ever recorded, and accounted for nearly one- third of all Chinese FDI. More recently, the volume of Chinese FDI in Europe has reached the level of European FDI in China (now constrained by restrictions and risks). It matched the level of FDI by Chinese companies in the United States before declining over the past two years, generally due to Covid-19 and the war in Ukraine. Chinese economic presence in Europe can be divided into three areas based on size, destination, and type of acquisition: The core of Europe is formed by the three major target countries (Germany, UK, France), where more capital-intensive investments are made, followed by other Western European countries (EU-15). The new member states (NMS), which joined the EU in 2004, 2007 and 2013, as well as the Western Balkan countries in the process of accession, are associated with China in the 16+1 format (with the exception of Kosovo) and form another gateway to Europe. Due to fewer market opportunities, they receive less direct investment, but China is building infrastructure (ports, highways, railroads) - segments of the Silk Road that will bring Chinese products to mature EU markets (Richtet, 2019). It is unlikely that Chinese investment in Europe will recover in 2023. The Chinese government is expected to maintain strict capital controls, financial retrenchment, and Covid-19 restrictions. The war in Ukraine and the expansion of regulations to monitor and control Chinese investments in the EU and the UK will cause additional difficulties. Originality/value: The article could be an attempt to answer the question of combining macroeconomic and institutional factors to better understand the internationalization of firms (Dunning, Lundan, 2008). There is no doubt, that the Covid-19 pandemic and the war in Ukraine made it necessary to deepen the study of the phenomenon of FDI, its inflows, determinants, and related challenges in a turbulent world.

The European legislation sets targets for ending municipal waste to landfill. Despite this Europe-wide trend, almost half of the municipal waste generated in the Czech Republic has been landfilled in recent years. The composition of municipal waste, in particular the high content of biodegradable material, is the reason for landfill gas production. The management of landfill gas is one of the crucial elements of environmental protection in the landfilling process. The article focuses on the comparison of possible ways of landfill gas management at selected landfills in the Czech Republic.

The article presents a comprehensive investigation into the prioritisation of environment-oriented Corporate Social Responsibility (CSR) activities among companies within the Visegrad region, encompassing the Czech Republic, Poland and Slovakia. An online questionnaire featuring Likert scale questions was used to collect data from November 2022 to June 2023 on the emphasis placed on 11 distinct environment-oriented CSR activities. Analytical methods covered descriptive and inferential analyses. The study contributes original insights by focusing on the Visegrad region's corporate engagement in environmental CSR activities. The findings reveal significant disparities between countries, particularly in the domains of eco-friendly transportation solutions and investments in green technologies for environmental progress. Statistically significant differences were observed between the Czech Republic and Poland, as well as between Poland and Slovakia, there by shedding light on the diverse CSR orientations and priorities within this geographic context. These findings underscore the importance of tailored CSR strategies within the Visegrad region's corporate landscape to address environmental challenges effectively.

The Covid pandemic and following restrictions worldwide influence various aspects -lockdown does not only have economic consequences but is also associated with a change in population mobility. As well as the spread of a pandemic and the associated numbers of infections and deaths, policy responses and restrictions have also varied from country to country. Despite all the negative impacts of the Covid pandemic, the decrease in crash-related injuries may be seen as one of the positive impacts of lockdown politics. The change in crash characteristics during the Covid lockdown may provide new insights and help design countermeasures for road safety improvement. It is not sufficient to generalize findings across individual countries, there were different trends in crash frequency and severity during the Covid lockdown The main purpose of this study was to investigate the Covid restriction's impact on road safety in the Czech Republic. The retrospective analysis was performed using data the Police crash statistics. In addition to data from the main Covid periods (2020 and 5 months of 2021 data), crash data from 2016-2019 as the period unaffected by the Covid pandemic, were used as a control group. The study focused not only on the overall crash frequency but also on the analysis of the crash frequency according to the individual crash participants. Crash data did not indicate significant changes in risky behaviour. The mobility decrease was associated with decreased crash frequency, especially of vehicles and pedestrians. The crash numbers also reflect changes in how people spend time, respectively an increase in leisure time activities in some age groups and a change in usage of transport modes. Two-wheeled vehicle users (cyclists, motorcyclists) crash frequency was more influenced by seasonality. While the crash frequency of vehicles (personal vehicles and HGVs) and pedestrians was better correlated with mobility data, the cyclists and motorcyclists crash frequency were better correlated with temperature.

In June 2021, a tornado struck a large area in southern Moravia, causing extensive damage to property owned by individuals and legal entities. A need thus arose to speed up the process of estimating the amount of insurance indemnity. This process involved local inspections and subsequent assessment of quotations from construction companies for repairs, as the adjusters did not have the time and resources to estimate the amount of damage using the usual method, i.e. an itemised budget containing a list of works, supplies and services necessary to restore a structure to its original condition based on an on-site inspection. This article contains a retrospective analysis of the accepted quotations and evaluates differences in terms of scope and price compared to the standard procedure. Four apartment buildings were selected for assessment of the insulation and roof repairs. The results show that there are clear discrepancies between the price as determined by the itemised budget using the usual prices and the construction companies’ quotations. The analysis of the selected buildings has indicated that the quotations can by no means be accepted without first establishing the total damage and its actual scope. Major damage caused by a natural disaster will still have to be estimated on the basis of a personal inspection of the damaged property and preparation of an itemised budget created in line with the applicable pricing system.

The article presents a reflection on the loss of historical and cultural heritage caused by the pursuit of energy efficiency reduction of buildings. The paper will present the post-war construction development in the Ostrava region, especially the completion of the railway network with the implementation of new railway stations. It is these stations, whose architecture refers to the success of the Czechoslovak Expo 58 pavilion in Brussels, that have faced increased interest in the last few years from conservators seeking to preserve these cultural assets for future generations. The author illustrates this with the example of the inappropriate reconstruction of the railway station in Havířov. The scientific method used is mainly the communication of the author’s own activist experience in saving the railway station from demolition and his own observations during the recent reconstruction of this object. The response to the activities of the Důl architektury association was very topical at the time and led to the production of a documentary by Czech Television titled Requiem for the Station (Hollander, 2015) from the series My Private War.

Tematem niniejszego artykułu jest refleksja na temat utraty historycznego i kulturowego dziedzictwa spowodowanej przez dążenie do zwiększania efektywności energetycznej budynków. W artykule zostaną przedstawione powojenne inwestycje w regionie Ostrawy, zwłaszcza ukończenie sieci kolejowej i realizacja nowych stacji kolejowych. Te właśnie stacje, których architektura nawiązuje do sukcesu czechosłowackiego pawilonu przygotowanego na Expo ’58 w Brukseli, od kilku lat cieszyły się rosnącym zainteresowaniem wśród konserwatorów, chcących zachować ich walory kulturowe dla przyszłych pokoleń. Autor ilustruje kwestię utraty tych walorów na przykładzie niewłaściwej przebudowy stacji kolejowej w Hawierzowie. Metoda badawcza wykorzystana w artykule to głównie przedstawienie doświadczeń autora jako aktywisty zaangażowanego w ratowanie stacji kolejowej przed rozbiórką oraz własnych obserwacji podczas niedawnej przebudowy tego obiektu. Odpowiedź na działalność stowarzyszenia Důl architektury była wówczas bardzo żywa i doprowadziła do wyprodukowania przez Telewizję Czeską filmu dokumentalnego zatytułowanego Requiem dla dworca (Hollander, 2015) z serii Moja prywatna wojna.

This study documents the atmospheric conditions and the development of a tornadic supercell in the Czech Republic, which occurred on the early evening on 24 June 2021. I used the data from the ERA5-reanalysis, vertical atmospheric sounding, synoptic map, and a Sentinel-2 satellite image to determinate the tornado route. As a result of the analysis, it can be concluded that the development of this tornadic supercell was caused by high CAPE values, amounting to around 5,000 J·kg-1, 0-6 km AGL wind shear 30 m·s-1, storm-relative helicity with values of 150 m2·s-2 and a wavy atmospheric front. The tornado occurred around 19:30 local time (1730 UTC) in the town Hrušky and moved north-east, reaching the town Hodonín. Based on satellite image derived from Sentinel-2, the widest point of the tornado reached 70 meters; it traveled a distance of about 20 kilometers and had a force of EF3/T5 on the Fujita/TORRO scale. As a result of this event, 6 people lost their lives, 200 people were seriously injured, and hundreds of buildings and cars were destroyed. Further studies on strong thunderstorm incidents in Europe are necessary for their better understanding and prediction.

The issue of assessing socio-economic impacts represent a key element of the decision-making process on the implementation of major public investment projects. The correctness of the decision depends both on the chosen principle of the socio-economic analysis and the input data. The presented article focuses on updating selected input values for the socio-economic assessment of railway infrastructure projects. Specifically, the simplified values of the estimated rail accidents costs. Accident costs are used for considering the change in the safety. At present, these values, which are also stated in the national methodological resources, are based on statistical data of the entire European Union and thus do not reflect the possible national specifics of projects implemented in the territory of individual Member States. The principle of updating values is from a methodological point of view based on the original calculation principles, however, involves a set of information items on the occurrences that emerged in the past in a specific area. The output of the article is a set of methodological steps considering national conditions when determining the average accident costs, subsequently verified on a case study of the railway network in the Czech Republic. The outputs of the presented article directly build on the results of the research project in which the team of article authors has been involved. The research results refer to different values of accident costs uniformly determined for the entire European Union territory and those determined individually for the conditions of the railway infrastructure in the Czech Republic.

Supply chain security is one of the challenges many countries are currently addressing. As this topic is a national security prerogative, the systems for screening also vary. The Czech Republic is preparing a legislative framework to protect strategically important infrastructure from high-risk suppliers. This commentary focuses on the Czech Republic’s progress in this area, particularly in the European context.

Fire has major impact on species diversity in natural ecosystems around the world. The consequences of fires for invertebrates can be immediate, and recovery of species assemblages may be a long-term process. We recorded moth communities from May to November 2019 in a pine forest in Western Bohemia, Czech Republic, where a local fire occurred in April of that year. We used UV light traps at one burned site and two neighboring unburned sites with a similar character as the burned site before the fire event. We analyzed moth assemblages using several species diversity indices – index of dominance, Shannon-Wiener index and Shannon-Wiener evenness, Simpson index, and Chao1 nonparametric estimation. We detected 67 species at the burned site, and 97 and 106 at the unburned sites. The three most frequently trapped species at all sites were Macaria liturata, Buphalus piniaria and Thera obeliscata, representing common forest geometrid moths. We observed a decline in species number and abundance at the burned site compared to the unburned sites, probably due to the direct mortality of larvae. On the contrary, the burned site was more diverse according to the diversity indices. The fire disrupted the original character of the coniferous forest, which was proved by a decline of species feeding on conifers and Vaccinium spp. The burned site attracted species associated with dry habitats such as Eublemma purpurina, Charissa obscurata and Scopula rubiginata. Even though wildfires are viewed negatively in general, they might temporarily enhance diversity in a homogeneous landscape.

Statistical data on the values of financial indicators in individual fields in the Czech Republic are provided by the Ministry of Industry and Trade. Updated values are issued quarterly. However, within the statistical samples, there are on average 34 companies focusing on construction. Moreover, no document specifies the size of the companies. Although the scientific literature provides basic financial rules, this research has confirmed that companies of different sizes show different values of financial indicators. For this reason, one of the aims of the research described in the article was to verify the hypothesis that companies of different sizes have different approaches to financial management and the other aims was to focus on correlating data on key financial indicators of individual sizes of companies with statistics provided by the Ministry of Industry and Trade. Basic methods of financial analysis (vertical analysis), selected ratios and basic statistical methods, which include correlation analysis, were used. The analysis was performed on 30 samples of construction companies, which were divided by size into small, medium and large. The outputs of the research will be further used for the follow up research.

The review contains the discussion on the monumental catalog of medieval fortifications of cities and towns in the present-day Czech Republic by Vladislav Razím. The catalog has been published in parts by Národní Památkový Ústav in Prague since 2019. So far, parts two and three were published, which are devoted respectively to: part 2, in two volumes – to cities from the historic territory of Bohemia and Moravia, and part 3 – to the Czech part of Silesia. The first part – interpretative, will be a synthesis of the issues of urban medieval defensive architecture. Noteworthy are both the volume of the work, which includes a total of 260 catalog entries, as well as the capacity and length of the texts of individual entries, richly illustrated with the material from historical and architectural research – inventory, iconographic, and photographic. What is most important is the methodology of the research conducted, which was consistently applied in all of the developed defense objects, guaranteeing an in-depth recognition of their ori-gins, architectural changes, functions, and spatial context. Summing up, it can be said that the literature on medieval Czech defense architecture has been enriched with an exceptionally valuable position.

W recenzji omówiono monumentalny katalog obwarowań średniowiecznych miast i miasteczek z terenu obecnej Republiki Czeskiej, autorstwa Vladislava Razíma, wydawany od 2019 r. przez Národní Památkový Ústav w Pradze. Dotychczas ukazały się część druga i trzecia, poświęcone odpowiednio: część 2, w dwóch tomach – miastom z terenu historycznych Czech i Moraw, a część 3 – czeskiej części Śląska. Pierwsza część – interpretacyjna – będzie stanowić syntezę zagadnień miejskiej średniowiecznej architektury obronnej. Na uwagę zasługują zarówno objętość pracy obejmującej w sumie 260 haseł katalogowych, jak i pojemność oraz długość tekstów poszczególnych haseł, bogato zilustrowanych materiałem pochodzącym z badań historyczno-architektonicznych – inwentaryzacyjnym, ikonograficznym i fotograficznym. To, co najważniejsze, to metodyka przeprowadzonych badań, konsekwentnie zastosowana we wszystkich opracowywanych obiektach obronnych, dająca gwarancję dogłębnego rozpoznania ich metryki, przemian architektonicznych, funkcji i kontekstu przestrzennego. Podsumowując, można powiedzieć, że literatura poświęcona średniowiecznej architekturze obronnej Czech została wzbogacona o wyjątkowo cenną pozycję.
