Purpose: The paper aimed to analyze the profitability of the ten selected healthcare units in Poland before and after ownership transformation. Source data used for calculations came from the financial statements of the examined healthcare units. Design/methodology/approach: The paper focuses on ratio analysis, i.e., profitability, which facilitates the evaluation of the studied hospitals in two periods, 'before transformation' and 'after transformation'. A method of scientific cognition was used (1): an analysis of the subject literature, a method of obtaining empirical data (2): an analysis of the content of internal documentation of the analyzed healthcare entities (hospitals), and a method of analysis of the obtained empirical material (3): indicator analysis. Undertaken research contributed to the formulation of the research objective: Is there an improvement in the profitability of medical entities (hospitals) in Poland following ownership transformation? Referring to the presented research problem, the author formulated the following hypothesis: There is an improvement in the profitability of the examined healthcare entities in Poland. Findings: The study's results allow the author to verify the research hypothesis. The spatial scope of the analysis refers to the territory of Poland with a focus on three selected provinces: Lesser Poland (małopolskie), Kuyavia-Pomerania (kujawsko-pomorskie), and Lubusz (lubuskie). The time scope of the study covers three years before the transformation of a given 'SP ZOZ' (Independent Public Healthcare Institution) into a commercial law company and three years after the transformation. The subject scope of the evaluation includes: hospitals subordinate to local government units (LGUs) transformed into commercial law companies. The subject scope of the evaluation is the profitability of hospitals. Research limitations/implications: The results obtained are of great practical importance for managers, shareholders and other stakeholders in the health care sector. Nevertheless, the proposed considerations certainly do not exhaust all possible solutions and may be the subject of further research and scientific discussions. In the future, the author plans to expand the research results with the criterion of social effectiveness (quality of services provided and patient satisfaction with the services of medical entities). Practical implications: The results of the work can become an incentive for executives, managers and investors, as they indicate an improvement in the profitability of hospitals. Social implications: The implementation of the research results will contribute to increasing public awareness of the functioning of hospitals. Originality/value: The number of studies on the financial performance of medical entities is insufficient. All the more, the research results presenting the evaluation of the financial situation of the transformed entities are extremely valuable. The results from the conducted research indicate an improvement in the profitability of the examined medical entities (hospitals). In connection with this fact, legal changes resulting from normative acts (reforms in the healthcare sector) were also justified. The choice of topic results from the personal interests of the author.

The paper presents the objectives, nature, and importance of business education projects that affect the form of university-business cooperation. Design/methodology/approach: The article presents the barriers and advantages, that is, the factors determining the cooperation between the university and business. The study is based on the results of a survey of the target group participating in training courses, a literature review and focus interviews. Findings: The conducted research allowed to analyze the main barriers to cooperation between universities and businesses and identify measures to improve the efficiency of technology transfer and commercialization of innovations within educational projects. Research limitations/implications: The results of this work can become an incentive to undertake further research on the cooperation between universities and business. The study has certain limitations, resulting mainly from a small research group (32 people), however, it provides valuable feedback on the benefits of cooperation for recipients. Practical implications: The results can be used to develop educational activities aimed at forming an academic ecosystem of startups and increasing the effectiveness of cooperation between universities and business in the framework of scientific projects. Social implications: The implementation of research results will contribute to improving the level of education and employment of the population. Originality/value: As a result of the research, it was found that the implementation of business education projects can become a driver for the development of university startups and increase the interest of university employees in cooperation with business.

Purpose: The main purpose of this work is to analyze the attitudes, intentions and actions of young people in relation to educational programs on entrepreneurship. Design/methodology/approach: The survey of respondents was conducted through popular social networks in the region by filling out a questionnaire on the Internet. The sample group consisted of 179 people aged 17-35 years. Findings: Young people who refused to take part in an educational program on entrepreneurship, as a rule, have no ideas or projects for business and are characterized by zero entrepreneurial activity. Respondents from this group, in comparison with others, have a poor understanding of the goals and objectives of startups, and are also less likely than others to choose an intensive training program. All this may indicate that the real reason for the refusal of young people to participate in paid training programs may be a lack of motivation and a clear understanding by respondents of their vision of themselves as an entrepreneur. Research limitations/implications: The limitations of this study are related to the fact that the survey was of a regional nature for the target group of 17-35 years. In this regard, its results cannot be generalized. The results we have obtained provide a reasonable basis for further research on barriers to youth entrepreneurship. Practical implications: The research results are qualitatively, analyzed feedback from young people on the problems of low entrepreneurial activity which can be used to develop government measures to stimulate the private sector. In addition, the results provide a reasonable basis for further research on the role and relationship of financial and educational barriers to youth entrepreneurship. Social implications: The results of the research allow us to revise the measures of youth policy aimed at increasing entrepreneurial activity through the formation of sustainable behavioral entrepreneurial intentions. Originality/value: This study is an independent and comprehensive analysis of the low activity of young people in educational programs in the field of entrepreneurship.

W pracy przedstawiono wyniki badań odporności korozyjnej powłok cynkowych otrzymanych różnymi technologiami nanoszenia. Określono grubość otrzymanych powłok. Próbki poddano porównawczej próbie korozyjnej w obojętnej mgle solnej chlorku wapnia bez i z dodatkiem inhibitora korozji M-605 PS. Na podstawie wyników badań obliczono zmiany masy próbek i szybkość korozji powłok cynkowych w badanych warunkach. Przedstawiono je w formie graficznej na rysunkach 1÷4. Podczas próby korozyjnej prowadzono oględziny wizualne, które przedstawiono na rysunkach 5 i 6. Na podstawie przeprowadzonych badań stwierdzono, że dodatek inhibitora spowodował znaczne obniżenie szybkości korozji cynku nakładanego metodą zanurzeniową i metodą natrysku cieplnego. Po zastosowaniu inhibitora M-605 PS na powierzchni badanych próbek zaobserwowano mniejsze ilości białego nalotu produktów korozji cynku.

This paper presents the results of the corrosion resistance of zinc coatings obtained by different application techniques. The thickness of the coatings was determined. Samples were subjected to comparative corrosion in a neutral calcium chloride salt spray with and without the addition ofcorrosion inibitor M-605 PS. Based on the test results, the weight change of the samples was calculated and the rate of zinc coatings corrosion in the test conditions was determined. The results are presented in graphical form in Figures 1 to 4. During the corrosion test, a visual inspection was carried out, as shown in Figures 5 and 6. On the basis ofthe test results, it was found that the addition ofthe inhibitor caused a significant reduction in the corrosion rate ofzinc applied by immersion and thermal spray. After applying inhibitor M-605 PS on the surface ofthe samples, minor amounts ofthe white dust ofzinc corrosion products were observed.
