Full text linkPaweł Piechnik
Full text linkIn the “Author Gallery”, we present frames from Paweł Piechnik’s comic Bread of Freedom. It may be that, being surrounded by contemporary images diverse in content, form, genre, style, function and medium, we do not battle with ourselves over which religious content to depict, if any. Even Leo III the Syrian (with whom the iconoclasm dispute began) would not question such a “meeting” between a comic and religion, probably because the line and frame are not “deified”, but rather prompt questions about the limits of the image as the limits of religion – as is the case with Bread of Freedom – as the boundaries of metaphysics. But not everything can be presented and justified. The iconoclasm dispute has left many traces in Western culture, including those in the form of questions related to what might be presented. The comic Bread of Freedom designs unobvious responses to questions of this nature.W „Author Gallery” prezentujemy kadry z komiksu Pawła Piechnika Chleb wolnościowy. Być może, otoczeni współcześnie obrazami różnorodnymi co do treści, formy, gatunku, stylu, funkcji i medium, nie toczymy z sobą walk o to, które treści religijne przedstawiać, jeśli w ogóle. Nawet Leon III Izauryjczyk (od którego rozpoczął się spór o ikonoklazm) nie kwestionowałby „spotkania” komiksu i religii – zapewne dlatego, że kreska i kadr nie są „przebóstwione”, raczej prowokują do pytań o granice obrazu jako granice religii, a nawet – jak w przypadku komiksu Chleb wolnościowy – jako granice metafizyki. Nie wszystko bowiem, co się da przedstawić, da się też uzasadnić. Spór o ikonoklazm zostawił po sobie wiele śladów w kulturze zachodniej, między innymi w postaci pytań o to, co można przedstawić. Komiks Chleb wolnościowy projektuje nieoczywiste odpowiedzi na tego typu pytania
When the EU qualified electronic signature becomes an information services preventer
No full textPaweł Krawczyk has spent a decade in consulting on information security with a special focus on authentication and the digital signature. In this article, he discusses the practical failure of the qualified electronic signature (a digital signature) across Europe,illustrating that other forms of electronic signature are used far more readily, suggesting that the qualified electronic signature exist in a parallel reality, and that it is only used because governments pass laws to force people to use them

Historia przeszczepiania wątroby w Polsce
No full textPrace doświadczalne dotyczące przeszczepiania wątroby jako pierwszy w Polsce podjął Waldemar Olszewski wraz z zespołem. Miało to miejsce w 1972 roku. Dopiero 15 lat później, w 1987 roku, Stanisław Zieliński w Szczecinie i Marian Pardela w Katowicach podjęli próby przeszczepiania wątroby u ludzi. W 1989 roku próbę takiego zabiegu wykonali Jacek Pawlak i Marek Krawczyk w Warszawie. Pierwsze udane przeszczepienie wątroby w Polsce wykonał w 1990 roku Piotr Kaliciński w CZD w Warszawie. Przeszczepiania wątroby na początku lat 90. XX w. podjęli się także Jerzy Polański w Warszawie oraz Piotr Szyber we Wrocławiu. W następnych latach transplantacje wątroby wiążą się z trzema ośrodkami w Szczecinie oraz nazwiskami: Romana Kostyrki, Macieja Wójcickiego i Samira Zeaira. W Warszawie, w 1994 roku, Jacek Pawlak, Bogdan Michałowicz i Krzysztof Zieniewicz z dobrym wynikiem wykonali kolejną transplantację wątroby. Program ten zaczął bardzo dobrze się rozwijać i rozwija się nadal. W 2000 roku Wojciech Rowiński i Marek Pacholczyk utworzyli kolejny ośrodek transplantacji wątroby w Warszawie, a w 2005 roku Lech Cierpka i Robert Król – w Katowicach. W kolejnych latach przeszczepienia wątroby inicjowali: Maciej Słupski w Bydgoszczy (2017) i Zbigniew Śledziński w Gdańsku (2018). W rozwijających się ośrodkach transplantacyjnych wątroby szczególnie wiele zaangażowania włożyli: Paweł Nyckowski, Jacek Pawlak, Krzysztof Zieniewicz, Waldemar Patkowski, Tadeusz Wróblewski, Rafał Paluszkiewicz, Marek Pacholczyk, Andrzej Chmura, Maciej Kosieradzki i Marek Krawczyk – wszyscy zatrudnieni w Warszawskim Uniwersytecie Medycznym. We Wrocławiu bardzo aktywnymi w przeszczepianiu wątroby byli Dariusz Patrzałek i Paweł Chudoba. W 1996 roku powołano do życia Centrum Organizacyjno-Koordynacyjne ds. Transplantacji „Poltransplant”. Kierowane było ono kolejno przez Janusza Wałaszewskiego, Romana Danielewicza i Artura Kamińskiego. W 1999 roku Piotr Kaliciński i Marek Krawczyk rozpoczęli program pobierania fragmentów wątrób od żywych dawców i ich przeszczepiania. Do końca 2016 roku wykonano w Polsce 4186 przeszczepień wątroby oraz 314 transplantacji wątroby od dawców żywych. Obecnie aktywnymi ośrodkami są trzy jednostki z Warszawy: Klinika Chirurgii Dziecięcej i Transplantacji Narządów Instytutu „Pomnik Centrum Zdrowia Dziecka”, Klinika Chirurgii Ogólnej, Transplantacyjnej i Wątroby WUM oraz Klinika Chirurgii Ogólnej i Transplantacyjnej WUM. Poza tym aktywnymi ośrodkami są: Oddział Chirurgii Ogólnej i Transplantacyjnej Wojewódzkiego Szpitala Zespolonego w Szczecinie, Klinika Chirurgii Ogólnej, Naczyniowej i Transplantacyjnej SUM w Katowicach, Klinika Chirurgii Naczyniowej, Ogólnej i Transplantacyjnej we Wrocławiu. Programy transplantacji wątroby rozpoczęła także Klinika Chirurgii Wątroby i Chirurgii Ogólnej w Bydgoszczy oraz Klinika Chirurgii Ogólnej, Endokrynologicznej i Transplantacyjnej GUM w Gdańsku
History of liver transplantation in Poland
No full textExperimental research on liver transplantation was introduced in Poland by Waldemar Olszewski and his team in 1972. Not until 15 years later, in 1987, did Stanisław Zieliński in Szczecin and Marian Pardela in Katowice make an attempt of transplanting liver in humans. In 1989 another attempt was made by Jacek Pawlak and Marek Krawczyk in Warsaw. The first successful liver transplantation in Poland was performed in 1990 by Piotr Kaliciński at the Children’s Memorial Health Institute, Warsaw. Also, in early 1990s the attempts were made by Jerzy Polański in Warsaw and Piotr Szyber in Wrocław. In the next years, liver transplantations were connected with three centers in Szczecin and were associated with the following persons: Roman Kostryka, Maciej Wójcicki and Samir Zeaira. In Warsaw, 1994, Jacek Pawlak, Bogdan Michałowicz and Krzysztof Zieniewicz performed another successful liver transplantation. The program started to develop rapidly and is still up and running. In 2000, Wojciech Rowiński and Marek
Pacholczyk created another liver transplant center in Warsaw, while in 2005 Lech Cierpka and Robert Król did the same in Katowice. In the following years, liver transplantation was initiated by Maciej Słupski in Bydgoszcz (2017) and Zbigniew Śledziński in Gdańsk (2018). In the developing liver transplant centers, an exceptional contribution was made by Paweł Nyckowski, Jacek Pawlak, Krzysztof Zieniewicz, Waldemar Patkowski, Tadeusz Wróblewski, Rafał Paluszkiewicz, Marek Pacholczyk, Andrzej Chmura, Maciej Kosieradzki and Marek Krawczyk – all employed by the Medical University of Warsaw. In Wrocław, Dariusz Patrzałek and Paweł Chudoba were very active in the field of liver transplantations. In 1996, the Organizing-Coordinating Center for Transplantation POLTRANSPLANT was brought to life and at first was directed by Janusz Wałaszewski, then by Roman Danielewicz and Artur Kamiński. In 1999, Piotr Kaliciński and Marek Krawczyk started the program for liver fragment harvesting and transplantation from living donors. Until the end of 2016, 4186 liver transplantations including 314 liver transplants from living donors were performed in Poland. Currently there are three active centres in Warsaw, namely Pediatric Surgery and Transplantation Surgery, Children’s Memorial Health Institute; Department of General, Transplant and Liver Surgery, Medical University of Warsaw;
Department of General and Transplant Surgery, Medical University of Warsaw. Other active centres in Poland are Department of General and Transplant Surgery, Provincial Hospital in Szczecin, Department of General, Vascular and Transplant Surgery, Medical University of Silesia, Katowice, Department of Vascular, General and Transplant Surgery in Wrocław. Liver transplant programs have also been initiated at the Department of Liver and General Surgery, Bydgoszcz, and Department of General, Endocrine and Transplant Surgery, Medical University of Gdańsk
"United in Diversity": The Church's Experience and the European Union's Identity Motto. European Diversity and Autonomy Papers. EDAP 2/2008
Full text linkThe paper analyses a potential relationship between religion and politics in the context of the EU’s motto, unity in diversity. It’s aimed at verifying the thesis that claims the European Union’s identity motto has its roots in the ecclesial model of identity. The following analysis is a two–stage one. First, it considers whether the Church’s and the EU’s respective “unities in diversity” mean a similar thing; secondly, it elaborates the channels (cultural, ecclesial and political) through which the ecclesial model has been transferred into European politics. In the last part of the contribution, the author considers the significance of the ecclesial experience for the current European integration debates

List Locally Surjective Homomorphisms in Hereditary Graph Classes
Full text linkA locally surjective homomorphism from a graph to a graph is an
edge-preserving mapping from to that is surjective in the
neighborhood of each vertex in . In the list locally surjective homomorphism
problem, denoted by LLSHom(), the graph is fixed and the instance
consists of a graph whose every vertex is equipped with a subset of ,
called list. We ask for the existence of a locally surjective homomorphism from
to , where every vertex of is mapped to a vertex from its list. In
this paper, we study the complexity of the LLSHom() problem in -free
graphs, i.e., graphs that exclude a fixed graph as an induced subgraph. We
aim to understand for which pairs the problem can be solved in
subexponential time.
We show that for all graphs , for which the problem is NP-hard in general
graphs, it cannot be solved in subexponential time in -free graphs unless
is a bounded-degree forest or the ETH fails. The initial study reveals that
a natural subfamily of bounded-degree forests that might lead to some
tractability results is the family consisting of forests whose
every component has at most three leaves. In this case, we exhibit the
following dichotomy theorem: besides the cases that are polynomial-time
solvable in general graphs, the graphs are the only
connected ones that allow for a subexponential-time algorithm in -free
graphs for every (unless the ETH fails).Comment: 26 pages, 8 figure
