This publication deals with brewing beer by infusion and decoction technologies of mash production in microbreweries. Samples of two microbrewery beers are compared, namely Richard beer (Brno-Žebětín) produced in a double mash manner appropriate for the Czech brewing type, and beer samples taken at the laboratory microbrewery of Mendel University in Brno (MENDELU), where beer is produced in a simpler and less energy – demanding infusion method. At all the beer samples the basic analytical parameters of real extract, ethanol content, degree of fermentation and the extract of original hopped wort were measured using an automatic beer analyzer. The results coming out of the automatic beer analyzer are compared with the results of the beer samples analysis performed by liquid chromatography, by which the contents of oligosaccharides, maltose, glycerol and ethanol were measured. Both methods provide a number of analytical results for the comparison of decoction and infusion techniques, and analytical characteristics of both the brewing procedures. Emphasis is placed on statistical data processing and comparison of different types of beer and particular brews between each other, both in terms of production technology as well as beer sampling throughout the year.

The peculiarities of using mathematical and statistical data processing methods in studying the intensification in the process of sintering a ceramic material with a high content of high-calcium waste, and mineralizing sintering lithium-containing waste were studied. The region of optimal ceramic masses composition, which allows obtaining ceramic tiles with high functional properties, was defined.

Increased interest in the study of perfectionism of a person is becoming more and more relevant, it can be explained by the rapid pace of life, increasing competition, the cult of perfectionism and individual accomplishments. To diagnose perfectionism they use questionnaires, however, the vast majority of them have two scales. In the «Great Triennial Scale of Perfectionism», perfectionism is viewed as a richly varied construct that combines three types – «hard», «self-critical» and «narcissistic». In turn, each of these types is composed of several scales, which are included in the inventory in order to increase reliability and accuracy in the assessment. The results of the process of translation, adaptation and standardization of the quantifier are presented. Data on primary statistical data processing, reliability, validity of the technique, correlation and factor analysis of its indicators according to psychometric requirements are given. The reliability and validity of the instrument and the possibility to use it for investigative and psychodiagnostic purposes has been proved.

The article presents materials and research methods that are used both to identify an unknown person and to predict a person's susceptibility to illegal actions of varying severity. In particular, this article describes anthroposcopic, anthropometric, dermatoglyphic methods, statistical data processing and neural network forecasting, which are widely used in modern forensics and forensic science. The relevance and objectives of the above research methods are formulated in order to predict a person's propensity to illegal actions of varying severity.

Competence in an organization or company is important in supporting the performance produced by employees. The management of course will make efforts to increase the competence of its employees with the hope that the performance of the employees will make their work complete and the output produced is of high quality. Recognizing the importance of competence on performance, the authors helped by examining these variables. In this study the researchers collected data by distributing it to all employees at PT Batang Bumi Mandiri with a total of 25, of which the entire population will also be sampled because the sampling method used is the saturated sample technique. In processing this data used statistical data processing tools in the form of SPSS version 26 to assist the author in processing research data. The result of the research is that competence has an effect on performance. The competency variable also has a coefficient of determination of 16.5% to affect performance, while the remaining 83.5% is influenced by other variables not examined in this study.
