Authors: Kim Cheol-Woo , Yoo Hyo-Sang , Hong Sung-Kil
Published: April 2024

This study investigated the effect of cladding on tool steel (SKD61) by using 5%Cr-1.5%Mo-Fe powder (SKD61), which is expected to be economically effective when used to manufacture and mend die-casting parts. The cladding conditions were as follows: the distance between the coaxial powder supply head and the substrate surface was 20 mm, and Ar was used as the supply gas. The laser outputs applied in the cladding procedure were 3, 4, and 5 kW. The microstructure of the heat-affected zone in the processed specimens was analyzed, and the macrostructure and morphology of the substrate material were studied. Specimen hardness measurements were performed at intervals of 0.1 mm from the substrate surface to the core. As the laser output increased from 3 to 4 and 5 kW, the dilution rate increased from 10.6% to 11.8 and 13.2%. It was confirmed that the fraction of carbides increased as the laser output increased from 3 kW to 5 kW.

Authors: Jeon Hee Yeon , Park Mijeong , Han Seungheon , Lee Dong Hoon , Lee Young-In
Published: April 2024

Zinc oxide is considered an outstanding photocatalyst candidate, but its low photo-corrosion resistance is a problem to be solved. In the ZnO-ZnS core-shell structure, ZnS acts as a protective layer for the ZnO core, and thus, it can enhance stability and long-term performance. The ZnO-ZnS core-shell structure is synthesized into various nanoscale morphologies with high specific surface areas to improve photocatalytic efficiency. However, they are easily agglomerated and are hard to separate from reaction media. In this study, micro-sized bumpy spheres of ZnO-ZnS core-shell structure were prepared via facile chemical transformation of as-prepared ZnO. After sulfurization of the ZnO template, it was confirmed through SEM, TEM, EDS, and XPS analysis that a uniform ZnS shell layer was formed without significant change in the initial ZnO morphology. The ZnO-ZnS core-shell microsphere has shown superior efficiency and stability in the photocatalytic degradation of Rhodamine B compared with pristine ZnO microspheres

Authors: Park Minha , Lee Gang Ho , Kim Hyo-Seong , Kim Byoungkoo , Noh Sanghoon , Kim Byung Jun
Published: April 2024

Inconel 625 is typically used in extreme environments due to excellent mechanical properties such as high strength, corrosion resistance, abrasion resistance and low-temperature toughness. When manufacturing a hot forged flange with a thick and complex shape, the cooling rate varies depending on the location due to the difference in thermal gradient during the cooling process after hot forging. In this study, to evaluate the microstructure and mechanical properties of Inconel 625 according to the cooling rate, we performed heat treatment at 950°C, 1050°C, and 1150°C for 4 hours followed by water cooling. Additionally, temperature data for each location on the flange were obtained using finite element method (FEM) simulation for each heat treatment temperature, revealing a discrepancy in the cooling rate between the surface and the center. Therefore, the correlation between microstructure and mechanical properties according to cooling rate was investigated.

Authors: Kim Woo Cheol , Byun Jongmin
Published: April 2024

In this study, 316L stainless steel powder was used to produce a porous body that could be used in a specific environment. In contrast to the existing method of producing filters using only spherical powders, we attempted to produce filters using plate- and needle-like powders and evaluated their performance. In the powder preparation step, the shape change of the powder was analyzed by changing the size of the stainless-steel balls used for ball milling. Then, the variations in properties of the sintered porous body caused by the ball size were investigated. As the average ball size decreased, the average particle size of the powder decreased. Moreover, the surface area and pore size of the porous body decreased. Additionally, when balls of different sizes were mixed, the porous body showed a mixture of coarse and fine pores.

Published: April 2024

In this study, the effect of rolling of 1.25Cr-1Mo-0.5V-0.3C American Iron and Steel Institute 4340 modified steel for highspeed railway brake discs on the microstructure and mechanical properties was investigated. The materials were hot-rolled at 0%, 51%, and 66% reduction ratios, and then analyzed by optical microscopy, scanning electron microscopy, and electron backscattering diffraction (EBSD). needle-shaped ferrite block morphology in bainite varied with the rolling ratio. EBSD analysis reveals dynamic recovery and dynamic recrystallization, affected ferrite block boundaries and dislocation densities during rolling. Mechanical tests showed that hardness, toughness and elongation increase at higher rolling reduction ratio, while strength remained relatively constant. In particular, the impact toughness increased almost twice from the level of 70 J in S1 (0% reduction) to the level of 130 J in S3 (66% reduction). These results showed that the hot rolling can significantly improve the strength and toughness combination of cast brake discs material.

Authors: Jang Jin Kwang , Moon Jaeyun , Byun Jongmin
Published: April 2024

In this study, Bi-doped SnSe was fabricated through the high energy ball milling and the hydrogen reduction of Bi2O3, and its thermoelectric properties were analyzed. The specimen with pure-Bi was fabricated as a control group and properties were compared. In the case of specimens with added Bi2O3, when sintering was performed in a hydrogen atmosphere, Bi2O3 with a high melting point was reduced to Bi with a relatively low melting point. At this time, because of the appearance of the liquid phase, the orientation of the (400) plane increased, and the density was improved. As a result, the change of SnSe to n-type was confirmed in the temperature range of 300 K - 773 K due to Bi doping. Additionally, when Bi2O3 was used instead of pure-Bi, the thermal conductivity, which is inversely proportional to the figure of merit, decreased, and the electrical conductivity increased, resulting in an improvement in the figure of merit.
Investigation of Hydrogen Embrittlement of Haynes 617 and Hastelloy X Alloys Using Electrochemical Hydrogen Charging
Authors: Kim Jae-Yun , Kim Sang-Gyu , Hwang Byoungchul
Published: April 2024

This study explores the hydrogen embrittlement behaviour of two Ni-based superalloys using electrochemical hydrogen charging. Two types of tensile specimens with different geometry for the Haynes 617 and Hastelloy X alloys were electrochemically hydrogen-charged, and then a slow strain rate test was conducted to investigate the hydrogen embrittlement behaviour. Unlike the ASTM standard specimens, two-step dog-bone specimens with a higher surface-area-to-volume ratio showed higher sensitivity to hydrogen embrittlement because hydrogen atoms are distributed mostly on the surface area. On the other hand, the Haynes 617 alloy had a lower hydrogen embrittlement resistance than that of the Hastelloy X alloy due to its relatively large grain size and the presence of precipitates at grain boundaries. The Haynes 617 alloy primarily showed an intergranular fracture mode with cracks from the slip band, whereas the Hastelloy X alloy exhibited a combination of transgranular and intergranular fracture behavior under hydrogen-charged conditions.
The Effect of Addition Amount of Chromium Iron on the Bonding Strength between Alloy Steel Surfacing Layer and Steel Base Metal
Authors: Huang Fei
Published: April 2024

Fe-C-Cr-Nb alloy steel surfacing layers with different contents of C and Cr were prepared on 45 steel base metal by selfshielded flux-cored wires with distinct amounts of high carbon chromium iron addition and melt arc surfacing. The composition and microstructure changes of the surfacing layer were tested and analyzed. The surfacing test plate was processed into a pulling specimen, and the bonding strength between the surfacing layer and the 45 steel base metal was tested with a self-designed pulling test method. The fracture location of the pulling specimen and fracture characteristics were observed by a metallurgical microscope and a scanning electron microscope. The result shows that with the increase of the amount of high carbon chromium iron added to flux-cored welding wire, the content of C and Cr in the surfacing layer increases, and the NbC hard phase disperses. The microstructure of the steel matrix changes from mixed martensite + residual austenite to high carbon martensite + residual austenite, and then independent austenite appears. The hardness of the surfacing layer first increases and then decreases. The bonding strength between the surfacing alloy and the 45 steel base metal first decreases and then increases, and the fracture location is at the bottom of the surfacing layer or the fusion zone with mostly quasi-cleavage characteristics. When the additional amount of high carbon chromium iron reaches 13%, thee pulling specimen exhibits significant deformation with the highest bonding strength, and the fracture is close to the fusion line, where there are numerous tearing edges and shallow dimples.

Published: April 2024

Vanadium carbide is important for industrial applications because of its high hardness, high temperature resistance, high chemical, and thermal stability. It is generally obtained from the reaction between V and C powders at a high temperature ranging from 1100 to 1500°C. Investigations on these high strength, high abrasion resistant, hard materials have been intensified in recent years and consequently, significant improvements have been achieved. In this study, VC alloys are produced with low cost processes, by reducing the oxides of their components by SHS methods and ball mill-assisted carbothermal reduction. In the experimental stage, V2O5 was used as oxidized Vanadium source, Cblack as carbon source, magnesium and Cblack as reductant. In the study, VC powders were synthesized by two different methods and optimum production conditions were determined. Furthermore, the effect of different stoichiometric charge components and the effect of experiment durations were realized by X-ray diffraction, HSC Chemistry, and SEM analyses for different reductants.

Published: April 2024

Ultra-High Molecular Weight Polyethylene (UHMWPE) polymers have been used in biomedical applications due to its biocompatibility, durability, toughness and high wear resistance. To enhance the mechanical properties, various types of minerals are commonly utilized as fillers in UHMWPE. One of the minerals is dolomite, which has been recognized as a valuable mineral with versatile applications, particularly in the field of biomedical applications. This paper presents the tensile properties of UHMWPE composites that filled with dolomite and treated-dolomite at various filler loading (i.e., 1-5 wt.%). Nitric acid and diammonium phosphate were used to treat the dolomite. From the results, the peaks of the FTIR spectrum displays carbonate (CO3–2), phosphate (PO4–3) and hydroxyl (OH–) groups in the ct-dolomite powder sample while the XRD pattern reveals that using dolomite treated with 1M nitric acid resulted in the presence of calcium hydroxide phosphate (Ca10(PO4)5(OH)) and MgO. For tensile strength, UHMWPE/ct-dolomite composites show better tensile strength than the pure UHMWPE composites. Treated improve the dolomite filler and resulted in significantly better matrix-filler interfacial interactions and improve the properties.

Published: April 2024

The work done in this study is a preliminary investigation into the possibility of modelling the filling and solidification process of castings in molds made with the additive method. The work originated from an experiment to produce a bronze casting with a high tin content in an additive mold. The mold filling and solidification simulation was carried out in the MAGMASO FT program, and the lambda thermal conductivity coefficient used in the program’s material database was corrected based on the actual temperature values of the printed form. The results were compared with the modeling results for the physical properties of furan molds based on the program database. The microstructure of the castings obtained in the compared forms was assessed.
Investigation of the Durability and Performance of Gears Made of Glass Fiber, Carbon and Bronze-Reinforced Polytetrafluoroethylene Matrix Composite Material
Authors: Yakut R. , Düzcükoğlu H. , Akkuş H.
Published: April 2024

Polymer gears are often used in power transmission due to their numerous advantages. Heat accumulates on polymer gears during operation. Over time, this accumulated heat leads to damage; and shortens the service life of the gears. To prevent this, various fillers are added to the polymer materials. These fillers help to dissipate the heat generated on the gears. In this study, 25% glass fibers, 35% carbon powder, and 60% bronze particles were added to the polytetrafluoroethylene (PTFE) matrix to determine the wear behavior of gears. The properties of the matrix and the filler mainly influence the wear behavior of PTFE composites. The study showed that all composite gears with filler have better wear resistance than pure PTFE gears due to their better thermal stability. After the tests, it was found that the gears made of PTFE + 35% carbon additive had about 12 times better wear rates than those made of pure PTFE. Based on the average temperature values of the experiment, it was found that the mass temperature of gears made of 35% carbon-doped PTFE is about 38-39% lower than that of pure PTFE. This study contributes to the standard studies on heat build-up, thermal damage, and wear of gears made of polymers with different fillers and ratios.

Authors: Ścibisz K. , Krawczyk J.
Published: April 2024

This paper presents an analysis of non-metallic inclusions occurring in high-silicon steels containing about 3% Si of terms of their type, volume fraction and morphology. The inclusions were divided into 3 main groups: oxides, sulfides, nitrides which together can also form complex. The work was based on numerous metallographic observations in two sections (longitudinal and transverse to the rolling direction). The study was performed on three casts differing in chemical composition. The analyzed casts were characterized by a different content of non-metallic inclusions, which can be associated with slight differences in chemical composition. The analyzed results showed that the most common inclusions were oxides and nitrides. Sulfides occurred sporadically.

Authors: Ścibisz K. , Krawczyk J.
Published: April 2024

Improvement of magnetic properties of electrical steel can be achieved by reduction the size of magnetic domains. The application of local stresses through laser scribing leads to reduced core losses. In order to determine the effect of laser refinement conditions of magnetic domains on the properties of the soft magnetic material, four samples with a thickness 0.23 mm were refined. The refinement of each sample was carried out using different line energies of the laser beam. Estimation of the magnetic domain size was performed using the Jeffries method, the magnetic viewer was used to reveal the domain structure. The measurement of the magnetic properties was performed at a frequency of 50 Hz and an induction of 1.5 T. The analyzed results presented in this work indicate impact of laser refining on magnetic properties of grain oriented electrical steel depending on used laser beam energy.

Published: April 2024

The aquifers in the M’léta Plain are crucial for supplying drinking water and supporting industrial and agricultural water needs. However, they are facing a pollution risk and environmental degradation. The present study aims to assess the groundwater quality in the M’léta Plain, focusing on its physicochemical properties, statistics of the aquifer, pollution risks, and factors influencing the water mineralisation process. The analysis of 16 samples reveals that the water contains high levels of sulphates and chlorides, often accompanied by sodium, calcium, or magnesium. This suggests two distinct water types or facies: one characterised by sodium chloride or calcium chloride, and the other with calcic or sodic sulphate waters, sometimes including magnesium sulphate. These facies may be attributed to the influence of different formations at the outcrop. Statistical analyses reveal a strong correlation between electrical conductivity and the majority of chemical elements, indicating the impact of freshwater interacting with the underlying rock formations on mineralisation. Some results also show undersaturation of certain minerals. Furthermore, the study evaluates the water's suitability for irrigation in the M’léta Plain in accordance with Richards’ classification.

Authors: Mitsui Akiko , Rosen Sydney , Yaxley Page , Lapsley Janis , Tremolada Giovanni , Selmic Laura E.
Published: April 2024

OBJECTIVE

Thromboelastography (TEG) is a whole blood assay that yields global assessment of hemostasis, as it evaluates clot time, strength, and kinematics of clot formation and lysis. The main objective was to describe preoperative TEG findings in dogs that had an adrenalectomy performed and, secondarily, to describe TEG findings in the dogs with or without hyperadrenocorticism (HAC).

ANIMALS

30 dogs that had preoperative TEG and adrenalectomy performed.

METHODS

Medical records between 2018 and 2022 were reviewed. Signalment, diagnostic data, and perioperative treatment were abstracted.

RESULTS

53% (16/30) of the dogs were hypercoagulable, and none were hypocoagulable. Based on histopathology, 6 of 9 dogs with adenocarcinoma were hypercoagulable, 4 of 8 with pheochromocytoma were hypercoagulable, and 6 of 10 with adenoma were hypercoagulable. None of the 3 dogs with other histopathologic diagnoses or combinations of diagnoses (adrenocortical hyperplasia, poorly differentiated sarcoma, and both adrenocortical adenocarcinoma and pheochromocytoma) were hypercoagulable. Of the 14 dogs tested preoperatively for HAC, 4 of 8 HAC dogs were hypercoagulable and 2 of 6 non-HAC dogs were hypercoagulable.

CLINICAL RELEVANCE

The present report describes for the first time TEG findings for dogs undergoing adrenalectomy and suggests that the majority of dogs with adrenal neoplasia are hypercoagulable based on TEG results.

Authors: Rizos Ioannis , Gkrekas Nikolaos
Published: April 2024

This article focuses on the transformation of current global problems into mathematical data and the drawing of conclusions from the results. After a theoretical introduction that clarifies the philosophy of the above approach and provides an innovative description of the mathematical model concept, a method for describing and analyzing crises is presented, with the goal of measuring its influence on the observable system, whether at the EU, global, or other levels. Converting social issues into quantitative data provides a systematic assessment of the severity of crises and allows for comparisons across different crises and systems. The main conclusion of the article is that a mathematical model, such as the one introduced here, could, to some extent, describe, as a first approach, global problems and their interrelationship, and thus be useful to policy makers.

Political, Cultural, and Social Factors in the Transformations of the Children’s Book Market in Poland on the Example of Nasza Księgarnia Publishing House
Authors: Hojka Bożena , Jamróz-Stolarska Elżbieta
Published: April 2024

Poland’s turbulent history, marked by several changes in the political system, has combined with dynamic economic, social, and cultural factors to profoundly affect the operations of all industries, including the publishing sector. This paper outlines the development of Nasza Księgarnia (literally: Our Bookshop), a publishing house founded in 1921 whose one-century- long history perfectly embodies the profound transformations which the Polish market of children’s and young adults’ books has experienced from the moment Poland regained sovereign statehood in 1918, through the communist period and the political transition of 1989, to the beginning of the new millennium. The argument is theoretically underpinned by the framework proposed by Michael Bhaskar (Bhaskar 2013), and the operations of Nasza Księgarnia are examined in terms of its crucial notions of framing, filtering, and amplification. At the same time, Hans Heino-Ewers’s (Heino-Ewers 2009) model of children’s literary communication is applied to highlight the specific role of Nasza Księgarnia as a publisher for children and young adults. These two theoretical tools offer insight into the ways in which political and social changes affected the evolution of the publishing repertoire and the editorial form of the children’s book in Poland throughout and at the turn of the 20th century.
Ochrona dziedzictwa narodowego przed szkodliwym działaniem mikrobiologicznym. Warunki i środki zapobiegawcze
Authors: Bangrowska Agnieszka
Published: April 2024

This article aims to present the physicochemical methods and chemical agents used to com-bat microorganisms in library collections as well as in library rooms. Based on an analysis of documentation available at various library centres, the methods and chemicals used to destroy fungi and moulds were compared. The standard storage conditions of library collections were used. Library collections from different sources can be attacked by microorganisms because they are almost entirely composed of organic materials, forming nutritional matter for those organisms. Environmental supervision is only one of many ways to prevent and ensure proper book storage conditions, but it is not a suitable method for fighting bacteria, fungi, mould, etc. The ways and methods of library collections’ disinfection should be considered very broadly. Disinfection of the collection itself is not enough; this must be combined with disinfection of the storerooms and additionally the removal of all potential sources of infestation. Emphasis should be placed on the implementation of modern methods of destroying microorganisms which, of course, will not harm humans but will prolong the life of library collections. Moreover, libraries and warehouses should be equipped with appropriate equipment to maintain suitable climatic conditions.

Przekład jako element kultury fan fiction
Authors: Skrzypietz Nadia
Published: April 2024

Fan fiction is the work written by fans who produce their own literature (and not only) based on popular original works. Their activity is concentrated primarily online, which allows them to connect and facilitate the exchange of opinions. The works appearing on internet forums give rise to discussions, inspire the creation of new works set in the original universes as well as the translations that accompany them. Like all fan art, the translations are done by non-professionals, often very young people. The translation of works often belonging to the fantasy genre poses specific difficulties. It requires not only perfect knowledge of the present-ed world, one described in the original version of a given work, but also considerable creativity. As in the case of any translation, the foundation seems to be both mastering the original language and understanding the possible linguistic play the creators invite the recipient to enter. This article presents the advantages of fan involvement in the translation of fanfiction works and the dangers of poor translation.
Z papieru do sieci - sposoby funkcjonowania czasopism hobbystycznych w przestrzeni Internetu
Authors: Lubczyńska Aleksandra
Published: April 2024

The development of new technologies, including the Internet, has a huge impact on modern communication. In the near future, new communication channels may dominate the existing ones. This is also reflected in the offer of publishing houses and media companies. The progressive fragmentation of audiences is evidenced by the growing figures for thematic channels on television, the increased number of users of narrowly profiled websites and the developing readership of specialist newspapers, coupled with a decrease in interest in general press. All of this made the publishers aware that in order to increase the reach of their products and get to the widest possible group of users, they must take action aimed at diversification, i.e., expanding to a new level of communication. In this context, the aim of the article is to identify the typology of the most characteristic manner in which hobby magazines function on the Internet. Another goal is to verify the thesis that, as is the case with other segments of the Polish press, hobby magazines are also migrating to virtual reality. Taking advantage of the development of the Internet and strengthened media market, they may decide to colonise it. Using the method of media content analysis, 73 hobby magazines were examined and 5 ways of their functioning on the web were distinguished.

Published: April 2024

The aim of this article is to explain how young adults use their media competences to understand the digital reality in which they function on a daily basis. The article is preliminary in nature as it refers to the partial results of a larger research project on digital competences of young adults, which has been conducted since 2018 and concerns Polish users of the media sphere. The goal was to show the heterogeneous nature of the selected group in terms of competences necessary for the correct analysis, understanding and interpretation of media messages. In addition, the article highlights the importance of the cultural pattern and strategy of using online and interactive media in Poland. Their specificity results from actual deficiencies in the area of formal education. These shortages are related to the development of language, communication, media, digital and information skills at various stages of education (primary school, secondary school), which significantly affects the media competences of young adults.

Authors: Wachowicz Monika , Antczak Mariola
Published: April 2024

The issue of commentary channels has already been elaborated on in the English language literature. Polish scientists are also slowly starting to engage with the subject as well. This type of content includes popular video media available both in Polish and English on YouTube. Due to the minimal interest of Polish researchers in the subject and the lack of theoretical studies devoted to the issue in the scientific literature, there has been an attempt to organize the terminology related to this new research subject. For these aims, the following methods were used: bibliographic, critical analysis of the literature on the subject, analysis of the content of audiovisual materials on YouTube, deductive, heuristic, and comparative. The implementation of the set aims will certainly serve as a starting point for researchers to carry out further research in this area.
O nowym przekładzie Pentezylei Szymona Szymonowica (Szymon Szymonowic, Pentesilea / Pentezylea, przełożyła i komentarzem opatrzyła Elwira Buszewicz, Wydawnictwo Neriton 2022, ss. 207, ISBN: 978-83-67245-15-9)
Authors: Borek Piotr
Published: April 2024

In the oeuvre of Szymon Szymonowic, an outstanding Polish poet of the late Renaissance, Latin works occupy a prominent place, which led to him being called the Polish Pindar. One of his works is the tragedy Penthesileia that continues the themes of the Trojan myth. Printed for the first time in Zamość (1618), the work was not fully translated until 1778. Parts of the work were translated later. The latest translation by Elwira Buszewicz combines a vocabulary understandable to modern readers with a desire to reproduce the poetic artistry of the Latin original and a solid philological commentary. The bilingual edition with parallel printing of the Latin and Polish texts, which makes it possible to follow the translation continuously, was preceded by an extensive scholarly introduction. Its author outlined the state of research on Penthesileia and pointed out the antecedents of the theme of the Amazons in Greek, Roman, medieval, and modern literary traditions.
Nowy wspaniały świat. O książce Listopadové proměny.Česká a slovenská literatura v kontextu roku 1989
Authors: Maślanka Anna
Published: April 2024

The article is a discussion of the publication Listopadové proměny. Česká a slovenská literatura v kontextu roku 1989, in which Czech and Slovak researchers reflect on literary and publishing phenomena of the breakthrough period of political transformation in 1989. The texts collected in the book concern both the second half of the 1980s - when, as Alena Šidáková Fialová notes, cultural and literary activity resembled walking on a minefield - and the 1990s, when writers, publishers, and booksellers often had great difficulty adjusting to the new, capitalist reality. The very diverse themes of individual texts allow us to observe the effects of political changes on many different levels. The publication itself fills a certain research gap, bringing closer through specific phenomena of the era that largely shaped the way the Czech and Slovak literary world functions today.
O czeskim czytelnictwie (Jiří Trávníček, A Nation of Bookworms? The Czechs as Readers: Reading in Time of Civilizational Fatigue, Prague: Karolinum Press, 2021, ss. 212)
Authors: Rogoż Michał
Published: April 2024

Reading is one of the key communicative competences. Unfortunately, according to research conducted by the National Library, Poles read very little. It is completely different in the Czech Republic. The reading culture of our southern neighbors has been well developed and stable for years. In the book A Nation of Bookworms? The Czechs as Readers: Reading in Time of Civilizational Fatigue Jiří Trávníček analyzes the Czech reading culture in detail and in many aspects. Its current state is significantly influenced by the strength of tradition. The considerations presented here have a great advantage - they are conducted from different perspectives and using different methodologies. Trávníček willingly refers to theoretical works as well as uses specific figures on the book market and readership. He consistently warns against all kinds of simplifications and schematisms regarding the diagnosis of reading habits, because, as he rightly notes, there are no simple answers and clear classifications in this topic.

Wiedeńskie kontakty lwowskich bibliotekarzy. Z dziejów Austriackiego Stowarzyszenia Bibliotekarzy
Authors: Oxenius Sławomir
Published: April 2024

The Austrian Library Association (Österreichischer Verein für Bibliothekswesen) was one of the oldest associations of librarians in Europe, functioning in the years 1896-1919. Its goal was professional and scientific improvement as well as integration of librarians from different lands belonging to the Habsburg monarchy. The article presents the origin and activities undertaken by the Association, particularly the published periodical, which was thematically related to various aspects of working in libraries and the formation of the librarian profession. It also presented information about specific libraries (an address book of monarchy libraries was published). Lviv librarians who belonged to the Association actively participated in its operations: Rudolf Kotula published articles on, e.g., Polish libraries in Austria, especially the Library of the University of Lviv, as well as in other Polish communities. He also took part in an extraordinary congress in 1913, which revealed conflicts in the relationship between the Association’s headquarters and provincial librarians, as well as problems relating to the concept, financing and scope behind the periodical. This article uses source materials to date unknown in scientific communities.
Libro del infante don Pedro de Portugal: przykład fikcji w średniowiecznej iberyjskiej literaturze podróżniczej
Authors: Burkiewicz Łukasz
Published: April 2024

Księga infanta Pedro Portugalskiego, który podróżował po czterech stronach świata (Libro del infante don Pedro de Portugal, el cual anduvo las cuatro partidas del mundo) jest przykładem średniowiecznej „literatury fantastycznej” opartej na wcześniejszych relacjach podróżniczych i będącej ich kompilacją. W tym utworze nieznany autor wykorzystał na potrzeby stworzenia fikcyjnej relacji dzieje życia księcia Coimbry Piotra (Pedro), następcy tronu Królestwa Portugalii i brata słynnego Henryka Żeglarza, który w latach 1425-1428, prawdopodobnie w celach dyplomatycznych, odbył szereg podróży, nawiązując relacje z najważniejszymi ówczesnymi uczestnikami polityki europejskiej. W jej trakcie oddał się na usługi Zygmunta Luksemburskiego, wówczas jeszcze króla Niemiec, Czech i Węgier, a w okresie późniejszym cesarza, aby pomóc mu w krucjacie przeciwko husytom. Podróże księcia Piotra doprowadziły go do Aragonii na dwór Alfonsa V, jak i do Kastylii przed oblicze Jana II, jak również do Barcelony, Flandrii, krajów niemieckich, Anglii, Wenecji, Padwy, Ferrary i również do Rzymu, gdzie został przyjęty przez papieża Marcina V. Tymczasem w anonimowej relacji napisanej w języku kastylijskim przez nieznanego autora, określanego w większości wydań jako Gómez de Santiesteban, książę Piotr udał się do miejsc, gdzie nigdy nie był: na czagatajski dwór Timura, do władcy zaginionego królestwa chrześcijańskiego Księdza Jana oraz do grobu św. Tomasza w indyjskim Majapur. W celu stworzenia tej narracji autor Księgi wykorzystał wcześniejsze znane mu relacje z podróży, jak między innymi równie fikcyjny opis Jana z Mandeville czy nawet jeden z wariantów listu wysłanego przez legendarnego Księdza Jana, ale i jak najbardziej autentyczną relację Ambasada do Tamerlana (Embajada a Tamorlán) z kastylijskiej misji dyplomatycznej do Samarkandy, stosując kompilację wszystkich tych dzieł. Księga infanta Pedro Portugalskiego odzwierciedla szeroko rozpowszechnione w średniowiecznej literaturze wschodnie mirabilia, znane z innych wcześniejszych i ówczesnych relacji podróżniczych, co było swoistym ukłonem w stronę oczekiwań ówczesnego czytelnika, wpisującym się w podróżopisarstwo średniowieczne, uchodzące za literaturę fantasmagoryczną.

Biblioteka Fundacji Wiktora hr. Baworowskiego wobec międzynarodowej współpracy intelektualnej Ligi Narodów
Authors: Gwioździk Jolanta
Published: April 2024

Międzynarodowa Komisja Współpracy Intelektualnej (a później Międzynarodowy Instytut Współpracy Intelektualnej) utworzona przy Lidze Narodów była odpowiedzialna za inicjowanie, organizowanie i koordynowanie międzynarodowej współpracy intelektualnej. W tym zakresie z Ligą Narodów współpracowały komisje narodowe. Polska Komisja Międzynarodowej Współpracy Intelektualnej dokonała oceny stanu życia intelektualnego, którą przeprowadzono za pomocą badań ankietowych. Nawiązywanie współpracy odbywało się nie tylko na szczeblu krajowym, ale wiązało się z aktywną postawą organizacji lokalnych. Związek Polskich Towarzystw Naukowych we Lwowie (w tym Biblioteka Fundacji im. hr. Wiktora Baworowskiego) aktywnie uczestniczył w badaniach i sformułował konkretne oczekiwania dotyczące pomocy i współpracy międzynarodowej. W ten sposób Baworovianum mogło informować europejską opinię publiczną o swoich zasobach bibliotecznych i muzealnych oraz współpracować z Biblioteką Hoovera. Stało się to podstawą późniejszej współpracy międzynarodowej, polegającej nie tylko na korzystaniu z zasobów biblioteki (na miejscu i w wypożyczalniach międzybibliotecznych), ale także na publikowaniu źródeł i materiałów naukowych związanych ze zbiorami, a przede wszystkim na międzynarodowej wymianie publikacji z wieloma krajami.
Edukacja informacyjna w zapobieganiu rozprzestrzeniania się stereotypów kulturowych w Internecie. Wybrane rozwiązania
Authors: Gołda Agnieszka , Tomaszczyk Jacek
Published: April 2024

Ludzie „zmęczeni” nadmiarem informacji skłonni są do stereotypowego postrzegania innych osób, grup, relacji, wydarzeń czy faktów, które zwalnia ich z konieczności analizowania spraw, poszukiwania sprawdzonych wiadomości, selekcjonowania danych i rzetelnego oceniania. Archiwizowane w języku stereotypy upowszechniane są w życiu społecznym, stając się źródłem narastających problemów, negatywnych zachowań i dyskryminacji. Dlatego też postanowiono wskazać sposoby zapobiegania stereotypom kulturowym w internecie poprzez działania znane z edukacji informacyjnej. Wyniki badania dostarczają wiedzy na temat potencjału edukacji w zakresie kompetencji informacyjnych w zapobieganiu stereotypom kulturowym oraz promowaniu różnorodności i integracji. Badania te mają istotne implikacje dla edukatorów, decydentów i ogółu społeczeństwa, ponieważ podkreślają potrzebę nadania priorytetu edukacji informacyjnej w walce ze stereotypami i dyskryminacją.
