OPEN Repository

Welcome to OPEN - the Repository of Open Scientific Publications, run by the Interdisciplinary Centre for Mathematical and Computational Modelling, University of Warsaw, previously operating as the CeON Repository. The Repository enables Polish researchers from all fields to openly share their articles, books, conference materials, reports, doctoral theses, and other scientific texts.

Publications in the Repository are indexed by the most important search engines and aggregators and downloaded by users worldwide. We invite you to create an account, deposit your publications, and use the resources of the Repository.

Fundamentals of the presence of clergy in the media. Theological and canonical aspect
(Uniwersytet Kardynała Stefana Wyszyńskiego w Warszawie, 2025-01-31) Kołodziej, Marcin
The Church carries out Christ’s command to preach the Gospel also through the social media. This was pointed out in more recent times by the Second Vatican Council, which in its decree Inter mirifica, advocated the use of these tools. At the present time, the internet has also become an important space for the preaching of the word of God. The presence of clergy on social media seems necessary. Of course, it has its glows and shadows. Therefore, there is no shortage of indications in the Church’s theological reflection and post-conciliar legislation to structure the ministry of clergy in the media in such a way that it becomes a modern pulpit and serves the effective preaching of the word of God.

Marzenia wychowanków placówek opiekuńczo-wychowawczych
(Wydawnictwo Naukowe Kontekst, 2025) Kita, Adam; Uniwersytet Opolski
Praca została poświęcona problematyce marzeń wychowanków umieszczonych w placówkach opiekuńczo-wychowawczych. W celu zbadania marzeń podopiecznych placówek badaniem zostało objętych pięciu wychowanków umieszczonych w instytucjonalnej pieczy zastępczej. Przeprowadzone badanie miało na celu ukazanie marzeń podopiecznych, zawartych w problemach badawczych. Problemy badawcze obejmowały marzenia wychowanków, definiowanie marzeń przez podopiecznych, dążenie do spełniania marzeń oraz przedstawienie ich w rysunku plastycznym. W badaniu zastosowałem metodę indywidualnego przypadku, przy zastosowaniu trzech technik badawczych: wywiad, obserwacja i techniki projekcyjnej – analizy rysunku. Do wybranej metody i technik zastosowałem trzy narzędzia badawcze: kwestionariusz wywiadu, arkusz obserwacji oraz rysunek.

Assessment method for the hydraulic efficiency of urban drainage system components
(Elsevier, 2025-02-24) Pochwat, Kamil; Department of Infrastructure and Water Management, Faculty of Civil and Environmental Engineering and Architecture, Rzeszow University of Technology, Rzeszów
This study evaluates the performance of different retention solutions in stormwater drainage systems. The outcome of this study proposes a method to determine the hydraulic efficiency of different stormwater drainage retention components, in which instead of assessing retention capacities, the resistance time is used. The study was conducted in a laboratory setting, involving four different hydraulic units designed to increase channel retention in the drainage system. These units operate under diverse hydraulic conditions, including varying channel gradients, different inflow rates, and differential outflow reductions. The analysed units included a linear system (U1), a linear system with increased retention (U2 and U4), and a ring system (U3). The experiments conducted laid the groundwork for a method to determine the hydraulic efficiency of drainage components in situations where estimating efficiency based on the analysis of required capacities is impossible or very timeconsuming. The research results were utilised to assess the hydraulic efficiency of the studied hydraulic units U1-U4. The results of this study indicated a significantly higher efficiency of ring systems (U3) under all input scenarios at the highest tested flows (12L/s). In specific cases, its application allowed for over a 5-fold extension of the system’s correct operation time, and the determined hydraulic efficiency coefficient α values ranged between 4.5 and 11.4. For lower flows (10 L/s), the most effective system varied depending on the hydraulic conditions, with the channel gradient identified as the parameter that most significantly influenced the efficiency of individual solutions.
