  The precondition of a health conscious behaviour in a community is establishing a healthy development of the community, an important part of which is the community’s attitude to sports and health. A basic manifestation of this is whether the leadership of a specific settlement is committed to developing sports facilities and, on the other hand, to what extent residents make use of these facilities. The aim of our research was to point out the number of sports facilities currently available for catering everyday physical education introduced in 2012, leisure sports and competitive sport events in two different regions of Hungary. We also examined the resources available for maintaining the facilities and the degree to which existing facilities are exploited. Existing sports halls of the Northern Great Plain and Central Transdanubia were included in the research. We wish to emphasise, in regards to the infrastructural developments of the coming few years, that it is essential to consider the fact, even in the planning phase of facilities, that sport events in themselves do not make the facilities economically sustainable.

  This article analyses grain production and prices 1961-2014. We first describe the development in aggregated and relative allocation of land worldwide for wheat, corn and soybeans, and the growth in production volumes and yields. We then proceed by analyzing long-term price relationships. Finding that grain prices are strongly co-integrated, we estimate an Error Correction Model to see whether deviations from the long-run equilibrium are quickly adjusted. Furthermore, we investigate whether changes in land allocations for these principal field crops are best described as a continuous process or as a series of structural breaks, hypothesizing that events like the introduction of GM technologies and the “energizing” of corn after 2005 caused structural breaks in acreage shares and relative prices. Given the major and sometimes dramatic political events and technological changes during this period,one would expect to find significant structural breaks in grain production, yields and prices. However, our main conclusion is that grain markets generally adjust smoothly and continuously. Prices adjust quickly towards long-run equilibrium, and the results from a series of Chow tests indicate that the changes in relative land allocations have progressed as a relatively smooth process with few structural breaks.

  Pig-farming has a long tradition in Hungary, most significantly within the Alföld region. In my analysis I studied the lifespan of sows in two nucleus pig herds on the Great Plain, also examining the probability of the occurrence of different reasons for culling. During my research I collected data (from 2001 to 2010) relating to more than 10,000 sows from the farms conducting a breeding programme and I searched for the answer to the question of whether can I find a significant difference in the lifespan of sows with the same feeding and the same genotype if the floor type of farms is different (Herd A has a solid floor with straw and Herd B has a slatted floor). Regarding the reasons for culling ANOVA was used to investigate mean differences in logarithms of the lifespan of sows in each herd. Between the herds the seven most common culling reasons were estimated with the Kaplan-Meier method and the significant difference was demonstrated with the logrank test. The results of the log-rank test showed that there was a significant difference in leg problems as a cause of culling and deaths (p < 0.05) between the two farms, which is the consequence of different floor types.

  The global energy consumption is continuously growing, because the population of Earth and the standard of living expands day by day. As a result, the emission of greenhouse gases increases further more. The various countries use the different types of fuels in varying amount.In this study we have examined the primary energy consumption of the countries, according to the BP Statistical Review of World Energy June 2016 (BP, 2016), based upon their usage of fuels.The assay resulted in a 7 cluster model. With one exception, each cluster contains a resource, which is used in a much larger amount than in the other clusters. As a result, we may differentiate between an average cluster, and the clusters of countries that use primarily hydropower, nuclear energy, renewable energy, coal, fossil oil, and natural gas.We have examined if there is any connection between the location of a country in a cluster and its HDI, as well as the countries’ competitiveness.
