Abstract Contamination of soil with potential risk elements is one of the most pressing environmental problems in the world and causes serious environmental damage, but also threatens human health. This paper presents the results of research that was focused on analyzing soil contamination in the field of magnesite mining in urban and agrarian land nearby the former factory in Košice (Slovakia). Field and laboratory research were performed. Soil sampling was performed in 10 localities of the studied area. The content of risk elements (Cd, Hg, Pb, Cr, Zn, Cu, As, Ni, Mn, Mg) in soils was analyzed under laboratory conditions. The obtained data expressed as average concentrations of metals in sampled soils, as well as background values of the contents of monitored elements for the soils of the Slovak Republic, were used to assess soil pollution and identify the environmental risk. The acquired knowledge about the contamination of the soil with risk elements in the area around the former magnesite factory in Košice could help in the planning of remediation measures and improve the state of the environment in the studied area.

Risk Sources

The issue of environmental risk assessment currently deserves great attention. In order to protect the environment, maintain healthy living conditions, and prevent environmental damage, the member states of the European Union have adopted a Directive of the European Parliament and of the Council on environmental liability with regard to the prevention and remedying of environmental damage. The directive classifies two types of operators with different liability regimes for environmental damage, namely, the regime with no-fault (strict) liability and liability for fault. With the adoption of the directive, among experts, operators and the general public have posed questions about how to assess the risk of environmental damage. At present, there is still no uniform procedure for assessing environmental risks, which would create a comprehensive methodological framework for assessment for this type of risk. Due to the non-existent risk assessment methodology for operators with strict liability regimes and the lack of a systematic search for risk sources, a risk assessment procedure is proposed that provides guidance in a sequence of several steps on how to implement the obligations arising from the adopted Environmental Liability Directive. The proposed procedure was verified on a specific operator with a strict liability regime. The environmental risk analysis performed through the proposed procedure provided information on possible operational problems and verified its applicability. Last but not least, the use of the proposed procedure makes it possible to identify serious sources of risk and to establish necessary preventive measures to prevent the occurrence of environmental damage.

Sources Of Pollution

Landfills, old and abandoned mines, industrial sites, heaps, sludge ponds and other sources of pollution represent environmental threats and are characterized as chemical time bombs. This work is focused on the evaluation of soil contamination by risk elements using various indices (geoaccumulation index—Igeo, enrichment factor—EF, contamination factor—Cif and degree of contamination—Cd). These selected agrarian problem areas are located in Slovakia, especially in the air pollution field of landfills consisting of power plant fly ash, tannery and footwear wastes, leachate (lúženec), iron ore slag, waste from metallurgy and sludge ponds in which coal sludge waste is deposited and waste from ore treatment. Nine research sites in the agrarian region of Slovak Republic were monitored. Ten risk elements (Fe, Mn, Zn, Cu, Co, Ni, Cr, Pb, Cd and Hg) and pH/H2O were included in this study and were determined in surface soils (of 0.05 m to 0.15 m) using atomic absorption spectrometry (AAS). Our study showed the highest exceedance of the limit values of risk elements in the order Ni (51.85 times) > Co (25.47 times) > Cd (13.70 times) > Cu (12.78 times) > Cr (8.37 times) > Fe (8.26 times) > Hg (7.94 times) > Zn (5.71 times) > Pb (4.63 times). The content of risk elements increased based on the average values of Igeo in the order of Cr < Hg < Zn < Pb < Ni < Cu < Cd. Igeo values for cadmium indicated mild-to-extreme contamination at all sites. We found the most significant enrichment in the order of Cd > Cu > Pb > Ni > Zn > Hg > Cr. EF values for cadmium indicated extremely high enrichment; the Cif and Cd values indicated a very high degree of soil contamination near the nickel smelter landfill, an industrial metallurgical plant and old but active mines. The studied areas pose a serious danger not only to the soil but also to groundwater and biota due to the prevailing low soil reaction, which increases the mobility of toxic elements. The study provides important results for the development of effective strategies for the control and remediation of endangered areas.

The objective of the paper is managerial evaluation of the level of logistics on individual continents and to find out dependence between the level of logistic systems and the level of GDP in the selected countries of the world. To evaluate logistics, we used the Logistics Performance Index and its six categories (customs clearance, infrastructure, international shipment, logistic competencies, monitoring shipment, and satisfaction). The index of gross domestic product was shown per capita and in constant U.S. dollars for 2010. The analyzed period was the years 2010, 2012, 2014, 2016, and 2018. Together, we analyzed 134 countries from five of the world’s continents. Results are provided separately for the European countries and the Slovak Republic. To find out mutual linear dependence, we used the correlation coefficient. From the results of the research, it is clear that there is a connection between the variables LPI and GDP and thus that there exists a direct linear dependence. Only in one case, that of the African continent in 2018, was the coefficient of correlation close to zero and we had to state that the variables were not linearly dependent. For most resulting values of the correlation coefficient, we found only slight linear dependence. The exception was the countries of Australia and Oceania, where a strong dependence was found for all the years in question. This kind of analysis has significance primarily on the macroeconomic level. The individual countries can investigate, evaluate, and consequently improve their respective logistic systems and services. Understanding and decomposing the components of trade and logistics performance can help countries improve freight transport efficiency and identify where international cooperation could help overcome barriers.

Drawing upon clinical psychoanalysis and laboratory research, this chapter develops an “embodied-relational” epistemology. The chapter reviews major research findings on the ways embodiment influences the cognitive processes by which we understand ourselves and the world. It also reviews current neuro-network studies whose findings imply the brain can be understood as a single, interactive system and not simply a collection of relatively autonomous domains. The emphasis here is on the brain’s complexity, integration, and a certain degree of openness. Sensory experience is understood as an active, not passive process, involving an intimate interconnection between self and world. The role of proprioception, as well as the five basic senses, is analyzed. The implications of such research findings for human understanding, and especially religious understanding, are elaborated.

Process of electronization is one of the milestones in the development of technological processes that leads to an improvement in the quality of life of citizens. The process of electronization is taking place all over the world. From the world leaders in the field of digitization of processes and data it is necessary to solve many things in the Slovak Republic, the development is in the right direction. The concept of national disclosure and delivery of important information is being addressed. The implementation of new information communication technologies and the introduction of processes have improved the awareness of citizens and businesses. By introducing open data into datasets, it also helps businesses to perform their activities more effectively. Open data contains non-personal data that is accessible to all and can be freely used, reused and distributed by everyone. This means that a certain type of data is available to everyone, in order to use and publish it at their own discretion, without restricting copyright, patents, or other control mechanisms. Improving aspects include raising awareness among citizens and businesses, improving the content of institutions providing such data, and so on. As part of the International Digital Economy and Society International Study, as well as the National Digital Economy and Society Index, a number of researches have been carried out that describe information and digitization. The paper lists the results of the survey focused on the ongoing development of the digital services.

Computer ethicists foresee that as information and communication technology (ICT) increasingly pervades more and more aspects of life, ethical issues increasingly will be computer-related. This view is underpinned by the assumption that progress is linear and inevitable. In accordance with this assumption, ICT is promoted as an essential component of development. This notion ignores the cultural origin of computing. Computer technology is a product of the Western worldview, and consequently, the computer revolution is experienced differently by people in different parts of the world. The computer revolution not only threatens to marginalize non-Western cultural traditions, but the Western way of life also has caused large-scale environmental damage. This chapter argues that computer ethics has to critically analyze the links between computing and its effects on cultural diversity and the natural environment and proposes that the Earth Charter can function as a framework for such holistic research.

For processes of environmental risk management, the results of a study of its perception are important. The identified priorities in the public concern about the state of the environment should be taken into account when preparing the necessary environmental measures. The prevention of risk or its reduction should take into account not only quantitative, but also qualitative characteristics of risk, which are caused by various factors and mechanisms of risk perception. Risk perception research data is essential for adequate risk communication, so managers involved in risk management should be interested in increasing the use of such data.

Avian malaria has historically played an important role as a model in the study of human malaria, being a stimulus for the development of medical parasitology. Avian malaria has recently come back to the research scene as a unique animal model to understand the ecology and evolution of the disease, both in the field and in the laboratory. Avian malaria is highly prevalent in birds and mosquitoes around the world and is amenable to laboratory experimentation at each stage of the parasite's life cycle. Here, we take stock of 5 years of experimental laboratory research carried out using Plasmodium relictum SGS1, the most prevalent avian malaria lineage in Europe, and its natural vector, the mosquito Culex pipiens . For this purpose, we compile and analyse data obtained in our laboratory in 14 different experiments. We provide statistical relationships between different infection-related parameters, including parasitaemia, gametocytaemia, host morbidity (anaemia) and transmission rates to mosquitoes. This analysis provides a wide-ranging picture of the within-host and between-host parameters that may bear on malaria transmission and epidemiology.

Concrete is the most commonly used construction material in the world over the past decades. But the increase in concrete production leads to an increase in greenhouse gases emission and environmental damage. With the current focus on sustainability, it is necessary to evaluate concretes environmental impact and develop new materials for green concrete. Green recycled aggregates and mineral admixtures are important component materials for green concrete. In this paper, the development of green concrete industry is introduced, and the application of materials for green concrete such as green recycled aggregates and mineral admixtures are discussed.
