Purpose: The changing financial situation of enterprises under the influence of various political, economic, social, etc. decisions is the cause of interest of many researchers. The aim of the research is to assess the financial situation of non-financial enterprises in Polish voivodships, taking into account the division into the private sector and the public sector in 2010-2020, and an attempt to classify the analyzed voivodeships into separate classes. Design/methodology/approach: Czekanowski's method was used to achieve the goal, which allows for the comparison of the examined objects in terms of the analyzed phenomenon. The visualization of this method is an ordered Czekanowski diagram, on the basis of which it is possible to group objects and observe whether their geographic location influences the results of grouping. Findings: The conducted analysis made it possible to group voivodeships in terms of the financial situation of enterprises, both for the public and private sectors. In the analyzed period, among the voivodships of Poland, several groups of similar voivodships can be distinguished in terms of the financial situation of enterprises. A voivodship was also selected, which differs from the rest of the voivodships – it is characterized by a lack of similarity in terms of the considered features, both in the whole analyzed period. It was also shown that the lockdown resulting from the SARS-CoV-2 pandemic had a significant impact on the financial results of Polish enterprises in the first half of 2020. Research limitations/implications: Using the MaCzek computer program to construct Czekanowski's diagrams, in some cases isolating similar objects in an unambiguous manner was difficult and hindered interpretation. Originality/value: Showing that the application of Czekanowski's method to the analysis of the financial situation of public and private sector enterprises in Poland is possible and allows for the assessment of the similarity of voivodeships. The article and the application of the method is useful for entrepreneurs and investors.

Purpose: The research on the composition of the optimal securities portfolio, conducted for many years, provides new tools and approaches not only to determining the shares of financial instruments in an optimal portfolio but also to the selection of instruments for the portfolio. One of the new approaches is the use of deterministic chaos to determine the composition of the portfolio. The purpose of the paper is to create company rankings and to assess the efficiency of investment portfolios built on their basis. Design/methodology/approach: In order to rank companies in terms of investment attractiveness, and to build and evaluate the efficiency of investment portfolios created on the basis of the division made, the analysis used such measures as: beta coefficient, Hurst exponent, synthetic measures: TMAI and WAI. Findings: The applied measures allowed to rank and divide listed companies due to the level of attractiveness for an investor. The research shows that better results were obtained for portfolios built on the basis of synthetic measures i.e. TMAI than WAI. Research limitations/implications: An important element of portfolio analysis research seems to be the use of tools such as the Hurst exponent. The research showed that the selection of shares for the portfolio based on the Hurst exponent often gives better or as good results as the methods taking into account the economic and financial situation of a company. Practical implications: The application in portfolio analysis. Originality/value: The WAI measures used to create a company ranking and build a portfolio of shares based on it. The application tools of deterministic chaos to determine the composition of the portfolio.

Obserwowane od wielu lat zmiany demograficzne w Unii Europejskiej wyraźnie uwypuklają proces starzenia się społeczeństwa, na który ogromny wpływ mają procesy płodności, śmiertelności i migracji. Zjawisko to jest ważnym problemem zarówno demograficznym, jak i społeczno-ekonomicznym, ponieważ prowadzi do wielu niekorzystnych konsekwencji, czyli np. do zmiany zasad funkcjonowania systemów zabezpieczenia społecznego, opieki zdrowotnej czy szkolnictwa. W starzejącym się społeczeństwie system opieki zdrowotnej odgrywa znaczącą rolę. Ze względu na rosnącą liczbę osób starszych rośnie popyt na usługi opiekuńcze i opiekę medyczną, a tym samym wzrasta liczba personelu medycznego oraz liczba miejsc w szpitalach, sanatoriach, kurortach i hospicjach. W opracowaniu zostanie przeprowadzona analiza przestrzenna rozwoju systemu opieki zdrowotnej w krajach Unii Europejskiej, a także zostanie zbadany wpływ procesu starzenia się społeczeństw na rozwój systemu opieki zdrowotnej.

The demographic changes in the European Union, that have been observed for many years clearly show the aging of the population, on which the processes of fertility, mortality and migration have a huge impact. This phenomenon is a serious problem of a demographic and socio-economic nature, because it leads to many adverse consequences, i.e., in policy changes in the functioning of social security systems, healthcare or education. In an aging society the healthcare system plays an important role. Due to the increasing number of the elderly population the demand for care services and medical care is increasing, and thus there is a corresponding increase in medical personnel, the number of beds in hospitals, sanatoriums, health resorts and hospices. The study includes a spatial analysis of medical care system development in the European Union and will research the impact of the aging society process on medical care system development.
