The weathering at the top of bedrock in Jurassic coalfield in northern Shaanxi is strong, and the formed weathered bedrock aquifer is the main water filling source of the mine, which poses a serious threat to the safe mining of the mine. The scientific evaluation of the water abundance of the weathered bedrock aquifer and the advanced drainage of the areas with strong water abundance are essential measures for preventing and controlling water disasters of the roof weathered bedrock. In this paper, taking Nanliang Coal Mine as an example, according to the drilling data, the weathering index, core recovery rate, brittle-plastic rock thickness ratio and rock structure index are selected to construct the evaluation system. The fuzzy analytic hierarchy process and coefficient of variation method are used to weigh comprehensively, and the water abundance of weathered bedrock aquifer in Nanliang Coal Mine is evaluated. The results show that the weathering degree of bedrock in Nanliang Coal Mine is strongly affected by ancient terrain, and the underlying Quaternary gully controls the thickness of the bedrock weathering zone. Combined with the evaluation results of mine water inrush status, the water inflow in the water-rich area is large.

The obligation to ensure transport accessibility of a territory in the Czech Republic is mandated by law. Services provided in the area of transport fall under the group of collectively- provided public goods and that is the reason for economic investigation of transport companies. These services cannot be provided efficiently with an eye on the profitability principle. The aim of this paper is to evaluate efficiency of management of 18 transport companies using a selected multi-criteria method. For this purpose, Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) is chosen in combination with the Coefficient of Variance method (CV) as an objective method for determining the weight of indicators. Analysis by means of CV-TOPSIS technique is carried out in 2006 and 2016 using 5 indicators, such as sales or short-term liabilities. Based on the results, authors can aver that the number of residents, i.e. number of the users of transport services, is not a significant factor that would affect evaluation of transport companies' efficiency in the Czech Republic. At the same time, transport companies in larger cities provided public transport less efficiently. In other words, with the growth of population, the transport company's economic efficiency decreased significantly, irrespective of the size of the territory for which the service of public transport was provided.

Research background: Social services are the main social tool used for the prevention and solution of social exclusion and its risk. Services of social prevention are focused on the wellbeing of the whole society and they prevent it from the influence of a wide range of socioeconomic phenomena related to social exclusion, understood in multidimensional terms. Purpose of the article: The purpose of the paper is to evaluate districts of the Czech Republic with respect to selected socio-economic factors that lead or can lead to social exclusion, when the emphasis is placed on the exclusion of children and youth, and to identify the causes of differences existing among these districts within the period of years 2011-2016. Methods: The paper focuses on multi-criterial assessment of districts of the Czech Republic using 23 indicators covering main aspects of social exclusion, which are processed with the Technique of Order Preference Similarity to the Ideal Solution (TOPSIS technique) in combination with the Coefficient of Variance method used to determine the indicators' weight. The results obtained using these methods are completed by the Moran's index, Shapiro-Wilk test, Mann-Whitney test, Kolmogorov-Smirnov test, Kendall Rank Coefficient and Levene's test. Findings & value added: A small number of districts with very negative assessment, with the presence of social exclusion and its higher risk, respectively, are identified. Differences among regions are constant and could not be assigned to randomness or disposable changes in the structure of indicators. Higher number of children born to unmarried mothers can be considered a typical aspect of the districts with higher risk of the social exclusion. The methods applied in the research, whose results and findings are presented in the paper, can be inspiring to further studies focusing on the social exclusion in its multidimensionality. The research is framed with the European Union discourse of social exclusion, thus the presented findings also open space for the comparisons and discussions of the factors associated with the social exclusion in other European Union Member States.

The presented research focuses on the commonly used Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS), which is applied to an evaluation of a basic set of 581 national hockey league (NHL) players in the 2018/2019 season. This is used in combination with a number of objective methods for weighting indicators for identifying differences in their usage. A total of 11 indicators with their own testimonial values, including points, hits, blocked shots and more, are selected for this purpose. The selection of a method for weighting indicators has a major influence on the results obtained and the differences between them, and maintains the internal links within the ranked set of players. Of the evaluated methods, we prefer the Mean Weight method, and we recommend that the input indicators be considered equivalent when evaluating athletes.

Culture is an irreplaceable means of transferring information between generations. The development of culture, the cultural environment, and the effect of culture exist over the long term. The results are not shown immediately, whereas the economics of subjects of this area (including theatres) are subject to public control. Public control forces these entities to use public finances efficiently, economically, and effectively. A sample of 11 indicators showing techniques and financial efficiency was chosen to conduct a complex evaluation of the economy of Czech theatres. The importance of the indicators was set by three objective methods used in combination by the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) for the evaluation of management. We show significant differences among the results; in our opinion, it is not possible to exactly set the best method that could be applied in general. Every method can potentially serve as a tool for complex comparison among homogeneous groups of theatres of the Czech Republic, depending on the preferences of their founder, in the public sector such as a municipality, region, or state.
