The Calculation of Social Benefits of Influenza Vaccination based on Statistical Data
6-24Views:51The goal we set in our study has had no precedent either in the Hungarian or in the international literature: our intention was to quantify the effectiveness of influenza vaccination based on facts, and to define the number of non-occurred diseases as a result of vaccination. We evaluated data from the influenza season of 2018/2019 in our study. We analyzed the available data on population, vaccination and the number of diseases, and drew objective conclusions therefrom. It was a problem that the basic data appeared in different data sets for different age groups, so we had to find a consensus between them, and establish comparable age groups. Ultimately, we defined three distinct age groups: the age group of minors (0-18 years), the economically active (19-59 years) and the age group of over 60 years. These three age groups became well distinguishable by population, vaccination, and morbidity. We described the influenza disease in general, the characteristics and variability of the influenza virus. We defined the typically affected age group, the number of patients to be treated, the trends for the past 5-10 years. The presented facts, numbers, the results of the calculations, and the conclusions drawn clearly show – excluding subjectivity – the preventive effect and effectiveness of vaccination, which was quantified for the first time in Hungarian literature.

Changes of soil chemical properties after sewage sludge compost treatment
40-48Views:43The small-plot experiment with sewage sludge compost (SSC) was started in the spring of 2003. Soil type is acidic Arenosol at the Research Institute of Nyíregyháza, University of Debrecen, in the NE part of Hungary. The applied SSC contained 40% of sewage sludge, 25% of straw, 30% of rhyolite and 5% of bentonite. Four treatments in five blocks have been conducted, where the SSC was applied at a rate of 0, 9, 18 and 27 t ha-1 and then was ploughed into the soil. Treatments were repeated in 2006, 2009, 2012 and 2015. Test plants were maize (Zea mays L.), triticale (x Triticosecale x Wittmack) and green pea (Pisum sativum L.) followed each other in a crop rotation every year. Composite soil samples were mixed from 5 subsamples in each plot from 0-30 and 30-60 cm soil layers after harvesting of test plants. Experimental results showed that composted sewage sludge Régiókutatás Szemle 2018 2. sz. DOI: 10.30716/RSZ/2018/2/5 application had positive effects on the chemical properties of the soil, especially the increase of pH and humus content.

Public collections of Szabolcs-Szatmár-Bereg county for regional researchers
18-29Views:45The public collection is a collective term, which contains national, local or public library’s, archives, picture and sound archives and museums. These institutions are collecting and systemizing document and allow them for use. There are public collections in ecclesiastical ownership and there are valuable private collections, which in some fortune cases serve scientific research in public collections. So is it in Szabolcs-Szatmár-Bereg County, where many public collections contain the history of the region, including the lives of the inhabitants, their naturals and the economic conditions. There are other serious sources besides the well know county library, archives and museum. The goal of this study is to introduce these not well-known sources for bigger audience. For an area where the border has been severely changed by the history, the importance of cross-border archives, virtual books and data are more relevant to researchers. Among national database this study presents a number of local portals such as the "olvass-sokat.hu" or the "Byzantinohungarica" portal which created by the Greek Catholic Heritage Research Group.

Testing the employee performance prediction capability of selection tests
6-17Views:78We can find several studies about employees performance in the management literature, but it remains an interesting topic in researches in the future, due to the increasing worldwide labour shortage. Finding the suitable employees is becoming more prominent among companies due to the increasing competition. The main aim of this study is to test the capability of selection tests (ability, readiness, competence tests) to predict employee performance. In order to answer this question employees (N=50) from a Debrecen based company in service sector have been analysed. General intelligence and conflict handling style have been estimated, as well as the evaluation of the employees by their supervisors. Some biographical data were used as control variables. The statistical analysis was based on descriptive statistics and multivariate, linear regression models. Based on the results we can concluded that being a female, having a university degree or the 1-3 years of employment at the company were in positive relationship with the employees communication skills significantly; the conflict handling style ’problemsolver’ tended to increase the expected value of the problem-solving skills; general intelligence was positively connected to the expected level of the Régiókutatás Szemle 2019/1 sz. DOI: 10.30716/RSZ/2019/1/1 7 measured job-specific skills; while no significant linear relationship was detected between in MS Office skills and other variables.
