Purpose: The overarching aim of this article is to divide EU countries into classes characterised by different levels of ecology in the field of air quality using factors in the form of emission levels of harmful substances into the atmosphere. The data included in the study concern the year 2017 and come from OECD STAT. Approach/Methodology/Design: The classification of EU countries was carried out using the cluster analysis method as one from data mining methods. The results confirmed the hypothesis that the European Union countries can be divided into three distinct classes according to the criterion of environmental performance in the area of air quality. Findings: In terms of the conditions considered for the international air quality test, concentration 3 was the best, namely Austria, Belgium, Bulgaria, Croatia, Denmark and Finland, Greece, Lithuania, Latvia, Malta,Portugal, Romania, Slovakia, Slovenia, Sweden and Hungary. These are the countries that place the least burden on the atmosphere from harmful factors. The countries belonging to cluster 2, namely Cyprus, the Czech Republic, Estonia, the Netherlands, Ireland and Luxembourg, have also achieved high levels of harmful agents. It should be clearly indicated that the lowest level of emissions of harmful substances into the atmosphere was found in cluster 1, and more precisely in France, Spain, Germany, Poland, Italy, the UK and Wolf. Practical Implications: It turns out that the good practices and recommendations of any sustainable development service do not achieve their purpose in comparison with other EU countries. It seems necessary to tighten the ban policy by imposing high fines on the prohibition of the use of all prohibited objects, devices which have a significant impact on the deterioration of air quality. Originality/Value: There are many reports on the market in the scope discussed above, rich literature compilations. The proposed model may contribute to further development in order to implement the proposed breakdown to reflect actual results in a way that does not seem to hide the worst performing countries. ; peer-reviewed

Purpose: The aim of this article is to determine how the local governments of medium-sized cities see a military unit located on their territory in the context of its participation in social and economic processes. Design/Methodology/Approach: The article presents the results of a research carried out using the diagnostic survey method, utilising the interview technique. For the analysis of the collected material and presentation of the results, the methods of Text mining as well as R v.3.6.1 program and RStudio editor were used. Findings: The use of text mining for the analysis of links between military units and local government units allowed to deepen the knowledge on the significance given by local government representatives to the presence of the army and its impact on socio-economic processes in specific territorial units. Practical Implications: The results of the research can be used in designing local development strategies and creating conditions for local agents to work together for development. In addition, they can be used to better understand the links between local governments and military units, by decision makers at the central level. Originality/Value: The results of the research indicate the possibility of using text mining for the analysis of complex links identified between entities on the territory of communes. Text mining allows to combine a qualitative and quantitative approach, in the context of identifying the impact of individual entities on the development of the commune and creating meanings in the process of interaction between entities located on its territory. ; peer-reviewed

Purpose: The aim of the research is to indicate the essence of strategic air transport management in the direction of security. Approach/Methodology/Design: The analysis of the literature review, the "case study" method, expert interviews and statistical analysis of the obtained data were used in order to formulate generalized conclusions that will be used to build reliability and safety models, and then to develop the concept of an IT support system. Findings: The problem of managing the transport of strategic goods is poorly recognized. The outsourcing of transport services to military entities takes place regularly and is an effective strategy to support PAF in the field of specialists and means of transport, Studies have found that PAF has a large number of errors. Companies that provide transportation services to military entities should be also prepared for securing side quests. As a result of the research, the strategy implementation procedures transport of goods, including procedures for commissioning transport from a civil carrier were founded. The frequency of adverse events that affect safety. The implementation of transport processes were also identified. Practical Implications: The conducted research will allow in the next stage to develop a detailed model management of the transport of strategic goods in the context of its safety. They will also make it possible to estimate the level of risk in particular phases model and allow us to develop organizational solutions that eliminate or limit frequency of adverse events. Originality/Value: The variety of research methods used and a comprehensive overview of interature allows us to clearly confirm the originality of the study. ; peer-reviewed
