Approach to the building of grain yield model is considered, depending on the intensity of application of mineral fertilizers. In order to improve the accuracy of the simulation, the system of ordinary Mono differential equations as a general model of the growth of processes' intensity in complex systems is used as the basis. The method of identification of the basic model, the efficiency of which is confirmed experimentally, is proposed. A comparison of the accuracy of the proposed model with known regression analogues is carried out.

The present study focuses on exploring the differences and relationship between well-being and experience of pastoral and psychological service of religious denomination based on religious affiliation during the first wave of the pandemic in Czechia. Our research has been focused on the investigation, comparison, and correlation between the level of well-being and pastoral and psychological service. The research sample (n = 1126) consisted of the Czech health population with age over 16 years, of which 42.4% were men (n = 478) and 57.5% were women (n = 648). From the perspective of religiosity, the study sample was divided in terms of religion into two groups—51.9% participants with religious affiliation (n = 584) and 48.1% participants without religious affiliation (n = 542). The level of well-being was identified by means of The Satisfaction with Life Scale (Diener, Emmons, Larsen, & Griffin, 1985). The level of experience with pastoral and psychological service was measured using our non-standardised questionnaire. The results confirmed the differences between the variables of well-being and positive experience with pastoral and psychological service based on religious affiliation. Moreover, we confirmed the hypothesis of a positive correlation between well-being and positive experience with pastoral and psychological service in Czechia.

Aim. The main aim of the authors of this study is to indicate the problem areas of individuals and the families during the pandemic and post-pandemic situation which occurred in connection with a deteriorating social and societal situation. Methods. Using a literary descriptive and deductive method, the authors identify, indicate and analyze not only epidemiological measures and the possibilities of applying social interventions in the individual and in the family, but also draw attention to state measures taken to manage new conditions of family life. Results. The analysis indicates a broad issue that affects individuals, families, and groups, as well as societal sectors. The authors point to the provision of interventions through social work, which takes into account the basic characteristics of the family. Social intervention therefore becomes an important tool in solving problematic situations of any small or large social group. Conclusions. The pandemic and post-pandemic situation brought about a number of problematic situations that had to be solved dynamically and, in many cases, through crisis intervention. Forms of assistance to individuals and families brought cohesion and unity, but also brought a number of other concerns reflecting the current adverse societal situation into the wider environment.

In the recent past, the question of determining the optimal city size in relation to the quality of urban life (QoUL) was raised of city inhabitants. This article has evaluated the correlation of the QoUL index in cities in relation to the number of inhabitants. We also deal with selected variables for which we assume a relationship with QoUL. The authors who calculated the indices of the quality of urban life equated the quality of life with its objective dimension considered as the quality of the place. It turned out that growth in the number of inhabitants of Slovak cities did not correlate with improving quality of life. Our article examined QoUL in two different countries on a scale of 0–10 through questionnaires. The obtained values are a subjective assessment. From a global point of view, one city is small and the other is big. The small city achieved better results in international rankings of quality of life, and it was assumed that this fact would also be reflected in the quantification of the quality of urban life. One hypothesis was that a small city will achieve better urban life quality values than a large city. The paper presents the results of measurement and correlation.

Aim. From the point of view of the period of creation and historical development, we consider the streets of the historical core of Trnava to be the most dynamic, and why we focused on street name changes in the period from 1900 to the present in the area of the historical core of the city. Methods. As part of the methodology the classification by urbanonym, with the help of which we included the names of streets and squares into individual categories. A classification was used that divides urbanonyms into socially motivated and socially non-motivated, which are further divided into several subcategories. Urbanonyms are further divided into domestic and foreign. This classification is the most up-to-date of those mentioned and includes a category of religious names. Results. The category of socially significant street names, are divided at a lower level into the categories of politics, art and culture, church, science, crafts and trade, historical names and institutions. The most numerous is the group of names in the art and culture category, which includes 70 domestic and 10 foreign names, which together represent 25.89% of the total number of streets in the city. There are 15 streets in the categories of politics, church and science (4.85% of all 309 streets). Conclusion. Currently, Trnava can be characterised as a modern, dynamic city with a great influence on its surroundings. The restrictive measures taken in connection with the coronavirus pandemic in 2020 greatly affected the tourism sector and meant permanent closure for many businesses.
