In the past decades the bed occupancy of hospitals in Hungary has been calculated from the average of in-patient days and the number of beds during a given period of time. This is the only measure being currently looked at when evaluating the performance of hospitals and changing their bed capacity. The author outlines how limited is the use of this indicator and what other statistical indicators may characterize the occupancy of hospital beds. Since adjustment of capacity to patient needs becomes increasingly important, it is essential to find indicator(s) that can be easily applied in practice and can assist medical personal and funders who do not work with statistics. Author recommends the use of daily bed occupancy as a base for all these statistical indicators. Orv. Hetil., 2011, 152, 797–801.

The article proposes an improved system of statistical indicators for assessing the state and development of the fuel and energy complex of Russia, which defines a methodological approach to identifying factors and trends in its development. The introduction highlights the relevance of modernization of information and methodological support for reaching decisions on new tasks, including those related to the digitalization of the economy and implementation of the national projects’ portfolio. The body of the article critically examines the current configuration of official and departmental statistical information, based on which the authors selected 85 key indicators reflecting the state and development level of the fuel and energy complex of Russia. All of them can be delineated by sectors and analysis tasks. This evaluation system includes 7 blocks: general block characterizing the role of the fuel and energy complex in the economic system; key industry performance indicators; indicators of the production structure by industry; technological indicators of industries; prices for fuel and energy resources; production costs by industry; distribution indicators of fuel and energy resources. The paper analyses development trends in the fuel and energy sectors for 2008-2018. In particular, the authors’ research showed that modern oil production is characterized by a change in the territorial structure, as well as the reinstatement of the role of vertically integrated companies in the development of oil production. The article presents findings on the technological upgrading of Russian oil refining. However, the authors’ research proved that oil refining depth has ceased to be a reliable indicator of the level of technological equipment and modernization level of oil refineries. With regard to the development of the gas industry, there has been a steady increase in gas production, which is supported by maintaining a steady increase in demand for Russian gas in the domestic and foreign markets. The all-time high domestic consumer demand for gas fuel, associated with the Russian Regions Gasification Program implemented by the Ministry of Energy of Russia, was recorded. At the same time, the authors identified the main risk factors in the development of the industry related to Gazprom (a backbone of the energy sector) activities. The persistent positive growth dynamics in commodity production of associated petroleum gas was established. It was also noted that the highest percentage of its beneficial use is characteristic of operators of production sharing agreements. As for the results of the analysis of the coal industry, a matter of interest is the growth of domestic prices for coal products and related derivative trends. Particular attention is paid to the development of the possibilities of using over-the-counter coal price indicators. Replacement of coal with natural gas at a thermal power station in most regions of the country is of interest within the identified development trends of the electric power industry in Russia, which is explained by the environmental friendliness of electricity generation.

The operation of the smart grid is anticipated to rely profoundly on distributed microprocessor-based control. Therefore, interoperability standards are needed to address the heterogeneous nature of the smart grid data. Since the IEC 61850 emerged as a wide-spread interoperability standard widely accepted by the industry, the Sampled Measured Values method has been used to communicate digitized voltage and current measurements. Realizing that current and voltage measurements (i.e., feedback measurements) are necessary for reliable and secure noperation of the power grid, firstly, this manuscript provides a detailed analysis of the Sampled Measured Values protocol emphasizing its advantages, then, it identifies vulnerabilities in this protocol and explains the cyber threats associated to these vulnerabilities. Secondly, current efforts to mitigate these vulnerabilities are outlined and the feasibility of using neural network forecasters to detect spoofed sampled values is investigated. It was shown that although such forecasters have high spoofed data detection accuracy, they are prone to the accumulation of forecasting error. Accordingly, this paper also proposes an algorithm to detect the accumulation of the forecasting error based on lightweight statistical indicators. The effectiveness of the proposed methods is experimentally verified in a laboratory-scale smart grid testbed.

Abstract The article analyses the role of institutions in the determination of income inequality in a sample of OECD countries. Basing on the seminal approach by Amable, the article discusses the theoretical definition of model of capitalism. The basic idea is that each model of capitalism is defined by the cobweb of complementary relationships established among different institutions. Using a set of statistical indicators of the operation of institutions in two different years, 1995 and 2010, the empirical analysis points out five models of capitalism and exhibits how their composition has changed in this lapse of 15 years. In the following sections of the article, we investigate the role played by the model of capitalism in the determination of income distribution, measured through a standard Gini index. After controlling for a set of variables, the econometric evidence shows that different models of capitalism present significantly different levels of income inequality.

Abstract This paper presents the implementation of a modified Genetic Programming (GP) method in forecasting fixed broadband telecommunications penetration percentage in Organisation for Economic Co-operation and Development (OECD) countries. The specific GP method combines the use of known diffusion models for technological forecasting purposes, such as Logistic, Gompertz and Bass and the GP. The combination method produces both time dependant and causal models with high performance statistical indicators. Also, multiple approaches to forecasting can be implemented, mainly with no big datasets.

The article presents an overview of the data of statistical observation of the Khabarovsk Krai, the Russian Federation and the Far Eastern Federal District (Okrug) on tuberculosis; their significance for assessing the epidemic situation and the quality of anti-tuberculosis care in these territories in 2002–2019 is studied. The dynamics of statistical indicators for 18 years is given using the methodology for calculating rank values. The dependence of the incidence of tuberculosis on the population density in the constituent entities of the country, the Far Eastern Federal District and its regions has been determined
