Opis:
Purpose: This paper aims to assess the sustainability of energy generation systems in various European Union countries. It seeks to understand the diverse challenges and opportunities these countries face in transitioning to sustainable energy. Methodology: The study employs a multi-criteria decision analysis (MCDA) approach, considering economic, environmental, and social aspects. Data from various databases, including Eurostat, the International Energy Agency, and the World Bank, were analyzed. Results: The results reveal significant variations in sustainability performance across different countries and regions. With strong policy support and high public awareness, Scandinavian countries generally performed well across all sustainability indicators. In contrast, Eastern European countries faced more challenges due to their heavy reliance on fossil fuels. Theoretical Contribution: This study contributes to the ongoing discourse on sustainable energy by providing a comprehensive assessment of the sustainability of energy generation systems. It underscores the complex and multifaceted nature of sustainability and the various factors that influence it. Practical Implications: The findings provide valuable insights for policymakers and energy providers. They highlight the importance of policy support, public awareness, and acceptance in promoting sustainable energy. They also underscore the need for continued efforts and interventions to address the challenges faced by countries heavily reliant on fossil fuels.

Opis:
For many years, the amount of waste generated on a global scale has shown an increasing tendency and their management and logistic is becoming a growing problem for most countries in the world. Waste management is an important issue to be addressed, as it concerns the three basic pillars of sustainable development: social, economic, and environmental. Therefore, it seems necessary to take initiatives to reduce the amount of waste generated and improve the waste management system. The article aims to analyse changes in the way of waste management and logistics in the European Union countries and the classification of these countries on the basis of the achieved effects in waste management. The article analyses three selected factors that reflect the effects of achieving environmental objectives in waste management. The cluster analysis method was used for the analysis. It found that EU countries differ in the quality of the results achieved in waste management, depending on the achievement of environmental management and sustainability objectives. In addition, the results of the analysis showed that the time factor has a significant impact on the classification of countries. High dynamics of the quality of effects in waste management were observed in the period under review.

Opis:
Improving product quality while making decisions remains a challenge. The objective of this research was to develop a model that supports the precise enhancement of product quality through comprehensive analysis of possibilities, product incompatibilities, root causes, and recommended improvement actions. The model incorporated various tools and methods such as the SMARTER method, expert team selection, brainstorming, Ishikawa diagram, 5M+E rule, FAHP, and FTOPSIS methods. The study demonstrated that integrating quality management tools and decision-making methods into a unified model enables the accurate prioritization of activities for product quality management. This integrated approach represents the novelty of this research. The model was evaluated using a mechanical seal made of 410 alloy. The research findings can be valuable to enterprises seeking to enhance product quality at any stage of production, particularly for modified or new products.

Opis:
The aim of the study was to answer the question whether or not determination of C-reactive protein in patients after serious abdominal surgeries can be prognostic of septic complications.Material and methods. 36 patients who underwent elective surgeries were included in the study. The patients were included either in the group where no postoperative SIRS developed or in the group where postoperative SIRS did occur. In the seven-day period after the surgery, in 26 patients SIRS was found, and in 10 - sepsis was suspected (according to the ACCP/SCCM definitions). In patients who underwent abdominal surgeries blood concentration of C-reactive protein was determined prior to the surgery (measurement '0'), and then on postoperative days 1, 2, 3, 5 and 7.Results. The test for two variables (C-reactive protein on postoperative days five and seven) showed statistically significant difference, and for one variable (C-reactive protein on day three) - difference at the limit of significance. Thus, it was found that in the postoperative SIRS group the level of C-reactive protein is higher than in the non-SIRS group.Conclusions. Serial measurements of C-reactive protein are useful in the first week after surgery, as they can be prognostic of postoperative septic complications. Such complications can be anticipated if CRP on postoperative day 5 is higher than 1/2 of the maximum CRP concentration on day 2 or day 3, or CRP > 150 mg/L as of postoperative day 3. Unfortunately, the severity of the disease cannot be projected based on C-reactive protein level.

Opis:
Purpose: The main aim of the study was to obtain feedback from patients with endometrial cancer on the quality of information provided to them prior to surgery. An additional aim was to correlate these opinions with sociodemographic factors. Material and methods: One hundred and twenty-three patients with endometrial cancer diagnosed by means of tissue sampling, treated surgically at the Department of Gynecology and Obstetrics in Rzeszów, Poland in 2012–2014 were enrolled in a prospective cohort study. The questionnaires used were: EORTC QLQ-C30 and QLQ-INFO25, completed before discharge from hospital. Statistical analysis assessed the influence of ordinal categorical variables by means of rank correlation analysis. For nominal variables, the mean and median values in the groups compared were calculated, and then the difference in the distribution of the domains of information quality in these groups was estimated using the Kruskal–Wallis test or the Mann–Whitney test. Results: According to data supplied by the patients who filled out INFO-25, they received the largest amount of information about medical tests (60.3%) and the disease itself (55%). They were informed less adequately about treatment (43.4%), and the scarcest information was provided in regard to follow-up (28.5%). The helpfulness of the information received (64.5%) was assessed the highest. Overall quality of their life amounted to 55 ± 22. A low correlation was found between the assessment of information and the quality of life. A younger age, higher level of education and having a partner correlated with a higher score awarded to the information received. Conclusion: The assessment of the quality of the information provided preoperatively depends on the individual characteristics of the recipient, which should be taken into account in the information process. In addition, more attention should be paid to the provision of information concerning the treatment protocol and follow-up.
Cel: Głównym celem niniejszej pracy było uzyskanie od pacjentek z rakiem endometrium opinii na temat jakości informacji przekazanych im przed operacją. Dodatkowym celem było skorelowanie tych opinii z czynnikami socjodemograficznymi. Materiał i metody: Prospektywnym badaniem kohortowym objęto 123 chore z rakiem endometrium potwierdzonym w badaniu histopatologicznym, leczone operacyjnie w Klinice Ginekologii i Położnictwa w Rzeszowie w latach 2012–2014. W badaniu zastosowano kwestionariusze EORTC QLQ-C30 i QLQ-INFO25 wypełniane przed wypisem z oddziału. W analizie statystycznej za pomocą analizy korelacji rang oceniono wpływ czynników mających charakter porządkowy. W przypadku czynników o charakterze nominalnym wyliczano wartości średnie i wartości środkowe w porównywanych grupach, a następnie za pomocą testu Kruskala–Wallisa lub testu Manna–Whitneya oceniano różnicę w rozkładzie miar jakości informacji w tych grupach. Wyniki: Z danych uzyskanych od pacjentek, które wypełniły moduł INFO25, wynika, że najwięcej informacji otrzymały one na temat badań (60,3%) i choroby (55%), mniej dowiedziały się o leczeniu (43,4%), a najmniej o jego kontynuacji (28,5%). Chore oceniły najwyżej przydatność informacji (64,5%). Ogólna jakość ich życia wynosiła 55 ± 22. Wykazano niską korelację między oceną informacji a jakością życia. Z lepszą oceną uzyskanych informacji wiązały się młodszy wiek, wyższy poziom wykształcenia i bycie w związku partnerskim. Wnioski: Ocena jakości informacji przekazywanych w okresie przedoperacyjnym jest uzależniona od indywidualnych cech odbiorcy, co należy uwzględnić w procesie informowania. Ponadto należy zwrócić większą uwagę na przekazywanie informacji odnośnie do zasad leczenia i jego kontynuacji.

Opis:
Investigations were performed to study the freeze-drying process of kale (Brassica oleracea L. var acephala). The process of freeze-drying was performed at temperatures of 20, 40, and 60°C for whole pieces of leaves and for pulped leaves. The kinetics of the freeze-drying of both kale leaves and kale pulp were best described by the Page model. The increasing freeze-drying temperature from 20 to 60°C induced an approximately two-fold decrease in the drying time. Freeze-drying significantly increased the value of the lightness, delta Chroma, and browning index of kale, and had little influence on the hue angle. The highest increase in the lightness and delta Chroma was observed for whole leaves freeze-dried at 20°C. An increase in the drying temperature brought about a slight decrease in the lightness, delta Chroma and the total colour difference. Pulping decreased the lightness and hue angle, and increased browning index. Freeze-drying engendered a slight decrease in the total phenolics content and antioxidant activity, in comparison to fresh leaves. The temperature of the process and pulping had little influence on the total phenolics content and antioxidant activity of dried kale, but significantly decreased the contents of chlorophyll a and chlorophyll b.
