Spółki z udziałem Skarbu Państwa – wyzwania prawne i faktyczne
Authors: Arndt Wojciech 
Published: December 2024

CEL NAUKOWY: Artykuł omawia zagadnienie spółek z udziałem Skarbu Państwa. Funkcjonowanie tych spółek wymaga racjonalnego uzasadnienia, związanego z połączeniem działalności gospodarczej i realizacji interesu publicznego. Ta współzależność stanowi poważne wyzwanie dla organów tych spółek. Istotnym instrumentem jest tu nadzór właścicielski (corporate governance) sprawowany przez kompetentne organy państwa.
PROBLEM I METODY BADAWCZE: Poważnym wyzwaniem jest optymalizacja wyników finansowych przy jednoznacznym spełnianiu kryterium interesu publicznego jako istotnym wyróżniku polityki właścicielskiej państwa. Pojawia się przy tym problem jednolitego rozumienia interesu publicznego, co w warunkach demokracji wydaje się dość oczywiste. W artykule przedstawiono analizę pojęciową i teoretyczną pojęcia spółki z udziałem Skarbu Państwa. W badaniu wykorzystano analizę aktów normatywnych, rekomendacji wyspecjalizowanych organizacji oraz literatury przedmiotu.
PROCES WYWODU: W artykule przedstawiono podstawę prawną funkcjonowania omawianych spółek, z uwzględnieniem reformy zapoczątkowanej w 2016 r. Wskazano też najważniejsze problemy występujące w działalności nie tylko polskich spółek z udziałem Skarbu Państwa, które należy w znacznej mierze postrzegać jako wyzwania. W następnej kolejności rozwinięto najważniejszą kwestię podnoszoną wobec omawianych spółek, jaką jest ich niższa efektywność, z uwzględnieniem wybranych teorii ekonomicznych.
WYNIKI ANALIZY NAUKOWEJ: Sposobem na przezwyciężenie zasygnalizowanych problemów jest ujęcie ich w szerszej perspektywie prowadzącej do problemu arbitralności. Jest to zagrożenie występujące przede wszystkim po stronie politycznej. Decyzje polityczne dotyczące kwestii merytorycznych oraz kadrowych wobec omawianych spółek opierają się często na woli politycznej nieopartej na solidnych analizach. Ma to niewątpliwie negatywny wpływ na działalność spółek z udziałem Skarbu Państwa, zwłaszcza przy każdorazowej zmianie władzy.
WNIOSKI, INNOWACJE, REKOMENDACJE: Reforma rozpoczęta w 2016 roku była krokiem w kierunku uporządkowania omawianego obszaru i podkreślenia celu realizacji interesu publicznego. Obowiązujące przepisy prawne wymagają faktycznego czynnika, jakim jest wymóg racjonalności podejmowanych decyzji nadzorczych. Często są to decyzje polityczne, które wymagają rozumnego działania, pozbawionego ryzyka arbitralności.
The Role of a University Teacher in Activating the Socially Marginalized Group of Retired Prison Service Officers
Authors: Urlińska-Berens Magdalena 
Published: December 2024

Research objectives (aims) and problem(s): The purpose of the study is to examine the role of university teachers in the education and activation of individuals in middle and late adulthood who belong to a socially marginalized group.
Research methods: Data were collected during the educational project “Academy RetroC@fe,” implemented from 2020 to 2024 at Ignatianum University in Krakow. Qualitative research was conducted with a group of 38 retired Prison Service officers affiliated with the National Union of Prison Service Retirees (KZEIRSW). The participants, aged 46 to 82, were engaged in educational activities. Empirical data were gathered using narrative interviews, group interviews, and e-documents produced as part of the workshops.
Structure of the article: This study focuses on issues related to the role of university teachers in the educational activation of retired prison officers belonging to a socially marginalized group. The research considers the backdrop of the COVID-19 pandemic, treated as a category of a “difficult situation.” The competencies of university teachers, which are key in working with adults, are described. Additionally, the study brings attention to innovative educational activities designed to support the development of adult learners in socially marginalized groups.
Research findings and their impact on the development of educational sciences: Learning in middle and late adulthood occurs without coercion. Activating and encouraging individuals to pursue educational efforts in later phases of life helps them adapt to a changing social world. It promotes positive aging patterns in which education enriches life experiences. The university teacher is instrumental in this process. Their competencies, along with their understanding and definition of their social role, greatly impact the educational path of individuals in middle and late adulthood.
Conclusions and/or recommendations: Educational activities for retired Prison Service officers broaden their horizons and equip them with key knowledge and skills that help them adapt to a dynamically evolving reality. By creating virtual learning spaces, university teachers, in effect, contribute to the individual development of retired prison officers and build their social capital—both by bridging and bonding social networks.

Published: December 2024

Vital pulp therapy for a carious exposure in a mature permanent tooth may be a reasonable alternative to root canal therapy or extraction. Mineral Trioxide Aggregate (MTA) or Biodentine are bioactive materials which are alternatives to traditionally used calcium hydroxide. They offer advantages like easy to manipulate, shorter setting time and relatively inexpensive. Pulpotomy, a conservative treatment modality for irreversible pulpitis is a newer concept in adult dentition. In properly selected cases, may contribute to the long-term mainte nance of tooth vitality. It is a biomimetic material having a positive effect on vital pulp cells and stimulates tertiary dentine or reparative dentine formation in direct contact with vital pulp tissue. This article presents two case reports, using Biodentine, which is a promising material having the potential to maintain pulp vitality in patients judiciously selected for vital pulp therapy.

RELEVANCE. Adenoid hypertrophy, mouth breathing can significantly affect the development and formation of the dental system in children. One of the most difficult to correct malocclusion pathologies is anterior open bite. The literature contains isolated, sometimes contradictory reports on the effect of adenoid hypertrophy on the development of this type of malocclusion.AIM. To study the prevalence of adenoid hypertrophy in children aged 7 to 9 years with anterior open bite, paying special attention to the characteristics of the factors determining the development of this malocclusion.MATERIALS AND METHODS. 60 children aged 7 to 9 years with an orthodontic diagnosis of anterior open bite were included in the study. The patients were divided into two groups (comparative and control) based on otorhinolaryngological anamnesis (adenoid hypertrophy). According to the lateral cephalometry data, the tendency to skeletal anterior open bite was estimated. The correlation between the development of malocclusion and the presence of adenoid hypertrophy was assessed using the Pearson coefficient.RESULTS. This study included 30 children with anterior open bite and 30 without malocclusion. There was no strong correlation between the formation of an anterior open bite and the presence of hypertrophy of the pharyngeal tonsil. The skeletal growth type index according to the LC data did not differ significantly in both groups, but the average vertical ratio for children with adenoid hypertrophy and mouth breathing was significantly higher for the control group (p = 0.05).СONCLUSIONS. The presence of adenoid hypertrophy in a child is not one of the main factors in the open anterior bite development. However, it is necessary to consider that adenoid hypertrophy and mouth breathing, especially for a long time, increases the risk of malocclusion development, effects on the growth of maxillofacial structures, which justifies the need for consultations of pediatric patients with related specialists.

INTRODUCTION. Chronic apical periodontitis (CAP) poses significant challenges in endodontics due to microbial resistance and inadequate disinfection protocols. Polyhexanide (PHMB) is a promising irrigant due to its antimicrobial properties. However, its interactions with other commonly used endodontic irrigants require further investigation to establish effective and safe clinical protocols. AIM. To evaluate the chemical interactions of PHMB with sodium hypochlorite (NaOCl), hydrogen peroxide (H2O2), EDTA, and chlorhexidine and identify optimal irrigation protocols.MATERIALS AND METHODS. The study utilized high-performance liquid chromatography (HPLC) to monitor reactions of PHMB with NaOCl, H2O2, EDTA, and chlorhexidine at intervals of 30 minutes, 1 hour, and 3 days. The analysis focused on detecting reaction products and assessing chemical stability.RESULTS. PHMB formed a precipitate when combined with NaOCl, leading to its complete depletion in the solution. Reaction with H2O2 produced new chemical compounds, while EDTA demonstrated no significant negative reactions. Mixtures with chlorhexidine generated new products and precipitates. Sequential use of EDTA and PHMB showed compatibility and potential for effective irrigation.CONCLUSIONS. Polyhexanide is a valuable irrigant for endodontics, particularly in combination with EDTA, as it provides smear layer removal and antimicrobial action without adverse interactions. Sodium hypochlorite and hydrogen peroxide require careful protocol adjustments to avoid chemical incompatibility. Further studies are necessary to confirm the clinical outcomes and refine protocols for safe and effective endodontic treatments.

Published: December 2024

The majority of children belonging to the Bajo tribe, residing on the coast of Bone Bay, do not complete their primary education. They are unable to remain in education until they have completed their studies. The objective of this study is to elucidate the underlying factors that contribute to the phenomenon of Bajo children dropping out of school. This research employed a qualitative approach utilising a case study design and a purposive sampling technique. The research subjects concentrated their attention on two primary schools where children belonging to the Bajo ethnic group are enrolled. Classroom and document observations were conducted, as well as unstructured interviews with two principals four teachers, and 12 Bajo children. The data were subjected to descriptive and qualitative analysis. The findings of this study indicate that four factors contribute to the inability of Bajo children to remain in school. These factors are (1) unsupportive environment, (2) irrelevant living habits, (3) inappropriate learning strategies at school, and (4) dense subject matter. The findings of this study have implications for school authorities, who should consider developing kinesthetic learning models in accordance with the environmental, social and familial characteristics of Bajo children. Further research is needed to clarify how to develop students' pro-environment syllabus with kinesthetic-based learning models.
