The importance of the number and viability of green areas for creating a com- fortable and safe life for residents of urbanized areas is increasing with the growth of cities, which has not stopped since the first half of the 20th century. Dnipro is a city with progressive air pollution, therefore the effective use of its green areas in this aspect – the selection of tree species, regular assessment of their condition and timely response to changes in vegetative activity – becomes especially relevant. To solve the research task, a combination of on-site and remote methods of assessing the vital state of green areas of the city was chosen. First, spatial and statistical information about the city’s green areas was defined and summarized, and a cartographic and statistical base of raw data was created, potential anthropogenic factors of influence were determined, and reference areas were selected. At the second stage, a systematic survey and assessment of the vital state of the trees of selected areas was carried out for seven years: morphometric indicators of trees of certain species and assessment of the state of their morphological elements (roots, trunk, crown, leaves). According to the degree of damage, trees were classified as: healthy, weakened (damaged), severely weakened; dying and dead. At the third stage of the study, the correlation of the vital state indicator (Ln) and the normalized vegetation index (NDVI) was determined, based on images from Landsat sensors 8 and 9 of the L1 processing level, pre-processing of the images was performed using the SCP (Semi-automatic Classification Plugin) module integrated in QGIS. According to the results of on-site research, it was found that for the period 2015-2021, most parks and squares of the control group belong to the second category (weakened), three to the first (healthy) and one to the third (severely weakened). The main types of damage have been identified as well as species of trees that are most susceptible to damage. The dynamics of vegetation activity indicators reflect the general tendency to increase the vegetation cover of the city for six years. According to the results of the correlation analysis of NDVI and Ln values, a stable dependence between the index of vital state and the normalized vegetation index was revealed. The correlation between the specified indicators for each particular year is direct and varies from 0.5 to 0.9. The vital state of forest park plantations in Dnipro city is at a satisfactory level. The average Ln for the entire city is 65.6%. It was concluded that the exploitation of the gas-absorbing capacity of plants must be carried out in combination with technical measures in order to activate the processes of improving the environment.

This article presents a comprehensive analysis of the natural recreational resources of Piryatinsky NNP, which are attractive for the development of ecotourism. To achieve this goal, the paper uses general scientific methods of scientific knowledge (analysis and synthesis from information sources), as well as the cartographic method. Recommendations for attracting more ecotourists have been formulated and an ecotourism bicycle route has been developed. To determine the period of maximum recreational activity, a phenological calendar of visits to the park’s protected area was created. The results of this study highlight that spring and summer provide the best conditions for a wide range of activities: animal and plant observation, walking along ecological trails, hiking, and representation of the entire natural complex of the Uday River floodplain. Species diversity in autumn and winter is much lower, so visitors are offered a range of activities including zoo ecotourism, landscape ecotourism, and aqua ecotourism. It is also worth noting that not all natural locations are easily accessible, as 40.1% of the land is covered by wet-lands. The development of ecotourism within Piryatinsky NNP is promising, given the significant species biodiversity and the fact that the NNP is part of the Emerald Network of Europe, including the world’s smallest flower plant, the wolfia. When studying a protected area to organise ecotourism, it is necessary to take into account the availability of tourist infrastructure – equipped recreational areas for tourists, rental offices, etc. Based on the above material, it can be noted that a favorable basis for the development of ecotourism in Piryatinsky NNP is the following: location (proximity to Chernihiv and Kyiv regions; the administrative center of Piryatin city community in Lubny district; landscaped and «undeveloped» areas), biodiversity (attractive objects; river valley terraces), bioclimatic and environmental favourability. The park also has ecotourism routes and an educational eco-trail. Thus, the considered NNP as one of the ecotourism sites in Poltava region is an interesting place for environmental research. The practical significance of the study will allow involving stakeholders (local residents, business organizations) in active actions to develop ecotourism. The information presented in this paper will allow for certain decisions to be made when developing a park management strategy, as well as in the geographical distribution of guide training.

Bevezetés: A COVID–19-osztályokon a betegeket ellátó
egészségügyi szakemberekre szélsőséges pszichés teher nehezedett, mely felmerülő
pszichés stresszorok rövid, közép és hosszú távon egyaránt éreztetik hatásaikat,
különböző pszichés tüneteket, megbetegedéseket generálva. A COVID–19-pandémia
pszichés szempontból is katasztrófahelyzetnek tekinthető, mely halmozott és
sűrített lélektani krízishelyzeteket jelent a betegnek, az őt ellátó
szakembernek és a társadalomnak egyaránt. Célkitűzés: A Dr.
Manninger Jenő Baleseti Központban végzett kutatásunk az Intézetben dolgozó
egészségügyi személyzet pszichés állapotát mérte fel a harmadik hullám
lecsengése után 2 hónappal, 2021 nyarán, még a negyedik hullám indulása előtt.
Módszer: Az online kérdőívcsomag kitöltésére 123
egészségügyi dolgozó vállalkozott, és ebből 88-an fejezték be a teljes
kitöltést. Az általunk alkalmazott mérőeszközök a következők voltak: Beck
Depresszió Kérdőív – rövid változat, Spielberger Állapotszorongás Kérdőív,
Események Hatása Kérdőív – javított változat, Megküzdési Módok Kérdőív. A
pszichopatológiai tünetek előfordulási gyakoriságát leíró statisztikával
jellemeztük, a demográfiai tényezők és a COVID–19-ellátásban való részvétel
hatásának vizsgálatára többszörös lineáris regresszióelemzést alkalmaztunk. A
megküzdési módok és a pszichopatológiai tünetek kapcsolatát Pearson-féle
korrelációval jellemeztük. Eredmények: A kitöltők 52%-a szenved
alvászavarban, enyhétől a súlyosig terjedő spektrumon. A dolgozók 61%-a szenved
a depresszió különböző súlyosságú tüneteitől. 88%-uk jelölte a krónikus
fáradtság tüneteit, különböző szinteken. 44,2%-uk szenved különböző erősségű
szorongásos tünetektől, míg 75%-uk szenved a poszttraumás stressz-zavar
különböző intenzitású tüneteitől. A dolgozók 29,8%-a számolt be megnövekedett
szénhidrát-, alkohol- és gyógyszerhasználatról. A szorongás és a depresszió a
családi állapottal, a poszttraumás stressz tünetei a foglalkozással mutattak
összefüggést, a magyarázott variancia azonban nem volt magas. Az érzelemfókuszú
megküzdés szignifikáns pozitív összefüggést mutatott a pszichopatológiai
tünetekkel. Megbeszélés és következtetés: Az általunk vizsgált
mintán a kapott eredmények alátámasztják a többi hazai és nemzetközi kutatás
eredményeit, miszerint a pandémia súlyos pszichés terhet rótt az egészségügyi
dolgozókra is. Fontos azonosítani a pszichés tünetképzés szempontjából a
fokozott rizikónak kitett csoportokat. Orv Hetil. 2023; 164(52): 2046–2054.
Hypermucinosus és kehelysejtszegény, gyulladásos bélbetegséghez társult, non-conventionalis dysplasia colorectalis adenocarcinoma mellett

A gyulladásos bélbetegséggel (IBD) élő betegekben a colorectalis carcinoma
kialakulásának esélye az átlagpopulációban észleltek kétszerese. Az invazív
daganatokat megelőzően ezekben a betegekben nagyobb a rizikó dysplasia
kialakulására is. Az utóbbi években számos, IBD-hez társult, ún.
non-conventionalis dysplasia altípust azonosítottak, melyekről a jelenleg is
zajló kutatásoknak köszönhetően egyre több információval rendelkezünk. Egy 62
éves, 14 éve relabáló colitis ulcerosával diagnosztizált és kezelt nőbeteg
subtotalis colectomiás preparátumában colitis ulcerosa mellett a sigmabélben
invazív adenocarcinomát azonosítottunk mucinosus területekkel. A daganat
közvetlen környezetében kehelysejtszegény, valamint hypermucinosus IBD-hez
társult, non-conventionalis dysplasiát észleltünk, az utóbbinak intestinalis és
foveolaris altípusa is elkülöníthető volt. A felhalmozódó ismeretek tükrében az
IBD-hez társult, non-conventionalis dysplasiák ismerete több szempontból is
fontos lehet a diagnosztikában és a klinikai ellátásban, ugyanis ezek a laesiók
makroszkóposan laposak vagy láthatatlanok lehetnek, megnehezítve a dysplasia
endoszkópos szűrését. Ismeretük a patológus számára kiemelten fontos, hiszen a
reaktív és reparatív folyamatoktól való elkülönítésük sokszor nagy kihívást
jelent. Továbbá, a hagyományos típusoknál gyakrabban társultak ’high-grade’
dysplasiával, valamint colorectalis carcinomával. Molekuláris hátterüket
tekintve, sokkal gyakrabban észlelhető bennük aneuploidia. Mindezen ismeretek a
hagyományos neoplasiákhoz képest rosszabb prognózis rizikót vetítenek elő, és az
esetlegesen nehezen azonosítható endoszkópos képüket is figyelembe véve
felismerésük után az IBD-s betegek szorosabb utánkövetése és esetleges
véletlenszerű biopsziás mintavétel mérlegelendő. Orv Hetil. 2023; 164(51):

The pandemic caused by COVID-19 represented a crisis situation of global proportions. The peculiarity of this event, its scale and its duration meant that existing crisis management procedures were put to an exceptional test. A particularly important sphere in dealing with the epidemic threat proved to be properly conducted communication with the public. Due to the specific nature of the epidemic situation enforcing social isolation and the scale of the event encompassing the entire world – it was the media that was the main source of information about the threat and ways to combat it. The aim of this article is to present and analyse the errors in communication conducted by state institutions towards the public through online media during the first six months of the COVID-19 pandemic in Poland.
The exosome isolation and characterization from DLD-1 cell line media
Authors: BAHAR Dilek , OZKAN Buket Banu
Published: January 2024

Exosomes, as extracellular organelles, are the most well-known vesicles among microvesicles. They are released from almost all body fluids as well as cells. Exosomes, which have gained popularity in biology studies with their nano-level dimensions (30-200nm) and membrane structures, are primarily used in drug encapsulation, regeneration, and cell-free cellular therapy. The fact that exosomes, which also function as biomarkers, have an ever-expanding area of use has led researchers to search for the isolation and characterization of this vesicle. In this study, the isolation of exosomes of the DLD-1 colorectal cancer line was carried out by ultracentrifugation method and characterized biophysically and biochemically by SEM, NTA, and flow cytometry, and the proliferative effect of these exosomes on HT29 cells, one of the other colorectal cancer lines, was investigated. As a result, it was proved that the isolated vesicles were morphological and size-appropriate to the literature and expressed CD63 and CD81 proteins. It was observed that DLD-1 exosomes increased proliferation on the HT29 cell line in a dose-dependent manner. Within the framework of the findings, this study could be an excellent reference for exosome isolation and characterization.

In this study, ion-imprinted polymers were prepared. These polymers can be used for the selective removal of Cu(II) ions from aqueous solutions. To this end, (E)-2-hydroxy-5-((vinylphenyl)diazonyl) benzaldehyde was used as a functional monomer in the synthesis stage of the polymeric adsorbent. Cu(II) imprinted poly[Cu(C15H11N2O2)] microspheres have been synthesised by dispersion polymerisation technique through interaction of the template molecule Cu(II) ion with the functional monomer. The specific surface area of Cu(II) imprinted poly[Cu(C15H11N2O2)] microspheres was 374.26 m2/g. The swelling rate was 80%. The maximum adsorption capacity, the optimum pH and the adsorption equilibrium time were determined to be 153.03 mg/g, in the 8-10 range and 30 min, respectively. The relative selectivity coefficients of the imprinted microspheres were found to be 13.09, 57.88, 44.719 and 35.006 for Cu(II)/Ni(II), Cu(II)/Pb(II), Cu(II)/Zn(II) and Cu(II)/Co(II), respectively. These results showed that the Cu(II)-imprinted microspheres were more selective with respect to Cu(II) ions. Reproducibility studies showed that Cu(II) imprinted poly[Cu(C15H11N2O2)] microspheres can be used repeatedly without significant decrease in adsorption capacity.

In the present research work, external flow-induced stresses on a circular cylinder with double-splined surfaces are
investigated at a Reynolds number Re of 100. Opposite sides of the cylinder have splined surfaces. The splines are
positioned between 0° and 90° from the cylinder's front and rear stagnation points. It is demonstrated that the spline on the cylinder's leading edge modifies the vortex dynamics and causes considerable changes in flow-induced forces. At Re = 100, when a spline is placed on a cylinder's surface, noticeable reduction is observed in the coefficients of lift and drag compared to a smooth cylinder. When the inclination angle is increased to a maximum of 60°, the stagnation point moves to the windward side. Additionally, the spline in the front and back side of the cylinder significantly strengthens the vortex flow. At inclinations of 90° and 0°, maximal and minimal vorticities are obtained. Furthermore, the present work's double-spline cylinder demonstrates the advantage of reduced drag over many previously reported bluff bodies.
Different Perspectives on Hegel-Mendelssohn-Relationship
Authors: Kiss Endre
Published: January 2024

In paragraph 157, Hegel describes in the Encyclopaedia the volume of the necessity, which represents a still inner and hidden identity which is "of those" that are considered as "real", the "self-sufficiency" of which should just be the necessity. While later Hegel describes the mutually independent realities (to repel something from themselves), he is (consciously or unconsciously) placed in a similar situation, in which Moses Mendelssohn comes in his essay written in 1763 for the Royal Academy of Sciences, while he is striving to build a rational metaphysics, a fully realized rational systematics. It is noteworthy, that in Mendelssohn's argumentation, the mathematical (geometrical and arithmetic) necessity (including the theological) can be on the way to cross over to the real. Mendelssohn's argument differs from Hegel's conception in important elements (amongst others, the language, linguistic usage, and the differences of conceptualities produced in the individual spheres, not to mention the relevance of the mathematical sphere). Still, the anti-empirical baseline can easily be brought in parallel with the same of Hegel. In his alleged strategical anti-Kantianism, Hegel might have found relevant help in many places in Mendelssohn.

Este artigo apresenta um estudo sobre o emprego de um sistema que utiliza técnicas de mineração de dados para identificar perfis de evasão e mau desempenho de alunos em um contexto de educação a distância, com o objetivo de alertar professores sobre a situação destes estudantes. Os alertas dão suporte à atuação do professor no acompanhamento dos processos de aprendizagem, com o monitoramento de perfis de alunos e de eventos no ambiente, notificando o professor sobre grupos de alunos que compartilham necessidades específicas. Os resultados de experimentos envolvendo 1780 alunos permitiram concluir que o sistema de alerta proposto pode contribuir com o aumento dos índices de aprovação e redução dos índices de evasão de disciplinas na modalidade à distância. Durante a pesquisa, também foi possível observar que o sistema de alertas contribuiu de maneira significativa na gestão do ambiente virtual de aprendizagem. Muitas das práticas docentes para engajamento dos alunos em seus estudos, bem como de resgate dos estudantes em processo de evasão, foram realizadas a partir do encaminhamento de mensagens aos alunos. A pesquisa mostrou ainda um alto nível de satisfação dos estudantes com relação a estrutura do curso e diálogo/comunicação com o professor. Também foram positivos os resultados quanto à percepção dos estudantes com relação a sua autonomia na realização das atividades do curso.AbstractThis article presents a study about the use of a system that employs data mining techniques to identify student evasion and poor performance profiles in a distance learning context, with the goal to alert teachers about the situation of these students. The alert system supports the role of the teacher in monitoring the learning process, keeping track of events and notifying teachers about groups of students who share specific needs. Experimental results involving 1780 students showed that the proposed alert system contributed to increase approval rates and reduce dropout rates in distance learning courses. It was also possible to observe that the alert system contributed significantly to the management of the virtual learning environment. Many of the teaching practices to engage students in their studies and rescue them from evading were based on email message exchanges. The research also showed a high level of student satisfaction regarding the course structure and their  communication with the teachers. Results were also positive regarding the perception of students with respect to their autonomy in carrying out course activities.

¿Qué características tienen los Cursos en Línea Masivos y Abiertos? ¿Cuáles son sus beneficios en comparación con otras modalidades formativas en línea? ¿Y sus principales limitaciones? ¿Qué tipo de competencias se requieren para realizar un MOOC y que tipo de competencias promueve? La aparición de los MOOC ha venido acompañada de fuertes críticas relacionadas con su valor pedagógico, los mecanismos de acreditación, el rol de los tutores, las dificultades para su evaluación o incluso el modelo mercantil de negocio que suponen. Sin embargo, al ser un fenómeno relativamente reciente, se dispone de pocas evidencias científicas acerca de su funcionamiento. Un modo de aproximación al estado de la cuestión es la consulta de las voces más acreditadas de nuestro país. Por ello el presente trabajo analiza en profundidad la opinión de 20 expertos en tecnología educativa de diversas universidades españolas a través del uso de una encuesta administrada a principios del 2014 con el objetivo de conocer su parecer respeto las características de los MOOC, sus beneficios y sus limitaciones. Los expertos coinciden en algunos beneficios a este tipo de formación como la accesibilidad y la posibilidad de aprender a lo largo de la vida con autonomía y constatan a la vez limitaciones respecto al grado de interactividad y la masividad, así como, especialmente, respecto a los procesos de evaluación que acompañan esta modalidad formativa.AbstractWhat characteristics do Massive Open Online Courses (MOOC) have? What are its benefits compared with other online training methods? And its main limitations? What kinds of competencies are required to make a MOOC and what competencies are fostered? The MOOC’ spread has come together with strong criticisms related to its educational value, the certification systems, the role of tutors, to the difficulties for its assessment or even the involved commercial business model. However, there are few scientific evidences about its operation, since the MOOC are a relatively recent phenomenon. A way to approach the state-of-the-art is asking the most reliable voices of our country. In this study we analysed in depth the point of view of 20 experts in educational technology from several Spanish universities by means of a questionnaire at the beginning of 2012 aiming at knowing their opinion about MOOC’ characteristics, its benefits and limitations. Experts from different subjects and degrees of Spanish Universities agree some MOOC’s benefits, such as accessibility and possibility of autonomous lifelong learning and at the same time, they perceive evident limitations relative to MOOC own features, interactivity and massivity and specially regarding assessment processes that characterise this training modality.

El sedentarismo representa uno de los principales problemas de la sociedad actual, siendo el «sedentarismo tecnológico» una nueva vertiente que surge del tiempo libre dedicado al uso de la pantalla, como es la televisión, ordenador y videoconsolas. Atendiendo a la etapa universitaria como un periodo en el cual se conforman los estilos y hábitos de la vida adulta, se realiza este estudio con el objetivo de conocer y analizar los hábitos sedentarios en relación al conocimiento y dedicación a los videojuegos de un sector de la población universitaria, comprobándose posibles diferencias en relación al género. La muestra contó con 490 sujetos universitarios con un rango de edad comprendido entre 20 y 51 años. Los datos se obtuvieron con un cuestionario sociodemográfico, de uso problemático y hábitos de consumo sobre los videojuegos. Los principales resultados determinaron que cerca de ocho de cada diez sujetos no presentaban problemas en relación a los videojuegos, siendo todos los casos con problemas severos sujetos masculinos. En torno a los hábitos de consumo, cuatro quintos del total mostraban un perfil bajo de adicción, siendo todos los casos de perfil alto sujetos masculinos. Señalar el consumo de pantalla como uno de los pocos factores potencialmente modificable en relación al sedentarismo.AbstractSedentarism represents one of the main problems of the actual society, being «the technological sedentary» a new dimension that arises from the free time dedicated to the use of the screen, such as watching television or playing video games. Attending to the university stage as a period in which habits of the adulthood are conformed, this study is realized with the aim to analyze sedentary habits in relation to the knowledge and dedication to the use of video games in a sector of the university population, studying possible differences in relation to the gender. The sample consisted of 490 university students with an age range between 20 and 51 years old. The information was obtained by a sociodemographic questionnaire and other which measure the problematic use of video games and the habits of consumption on these. The main results determined that near eight of every ten students did not present problems in relation to the video games use, being all the cases with severe problems related with masculine subjects. Concerning the habits of consumption, four fifth ones of the total shown a low profile of addiction, being all masculine cases associated with a high profile. Therefore, the consumption of screen represents one of few factors potentially modifiable in relation to the physical inactivity.

Este artículo presenta una investigación en la que se analiza la percepción de los docentes de la Universidad Nacional Autónoma de Nicaragua (UNAN-Managua), sobre el uso y funcionalidad técnica, administrativa y didáctica de las herramientas y recursos con base en las Tecnologías de la Información y la Comunicación (TIC). El estudio se afronta desde una metodología cuantitativa y, para ello, se emplea el cuestionario titulado: «Identificación de la Cultura Organizativa Universitaria» adaptado para Nicaragua (en su dimensión 9 referido a las TIC). Los resultados muestran que los docentes demandan una actualización pertinente y consideran que las TIC han de ser aplicadas como un objeto de aprendizaje, a través de los planes de estudio y, especialmente, a través de la asignatura de Informática Básica, presente en el primer año de todas las carreras de la UNAN-Managua. Asimismo, los docentes consideran las TIC como un medio de enseñanza-aprendizaje, en este sentido, han de estar presentes en la planificación de las actividades académicas, administrativas y de gestión universitaria. Finalmente, las TIC se consideran un recurso fundamental para fomentar el aprendizaje y como una herramienta en el trabajo independiente y colaborativo de los estudiantes.AbstractThis article presents a research in which the perception of teachers of the National Autonomous University of Nicaragua (UNAN-Managua) on the use and technical, administrative and educational functionality of the tools and resources based on the Information and Communication Technologies (ICT) are discussed. The study is approached from a quantitative methodology and, for this purpose, we use the questionnaire entitled: «Identification of the Organizational and Cultural aspects at University» adapted for Nicaragua (in dimension 9 refers to ICT). The results show that teachers demand a relevant and update training and consider that ICT have to be applied as a learning object, through the curriculum, and especially, through the Basic Computer subject, compulsory in the first year of all university studies at UNAN-Managua. Also, professors consider ICT as a teaching and learning resource and for this reason should be present in the planning of academic, administrative and management University activities. Finally, ICT is considered a crucial resource to encourage learning and as a tool in the independent and collaborative work of students.

Abstract: Many discourses emphasize the great educational potential of digital technologies. These technologies can renew both the activities carried out with students, the management of their learning paths, working methods, etc. In theory, this will be beneficial for education. But the evolution of these technologies in the field of education does not necessarily lead to idyllic results. In reality, the changes observed in these areas are slow and are based on very localized, rarely convergent, and often incomplete. Several elements are likely to determine the uses of computer technologies: the strategies of publishers and links with «EdTech» companies; political choices (in terms of curricula, equipment, examinations, etc.); materials (tablets, smartphones, etc.); educational resources, their modes of production and exchange, the place of free educational resources; changes in national and European legislation about digital matters. In this paper, we will try to show how the French publishing landscape and access to educational resources is currently undergoing important changes, starting from a configuration where textbooks are central to sketch out the current situation, where the supply of online digital resources seems to open up alternatives. We will rely in particular on the case of a portal of resources financed by the Ministry of National Education and published by consortia bringing together publishers and EdTech structures.

As a consequence of the technological advance and the massive arrival of ICT in the classroom, today we are experiencing a process of transition in schools that affects the teaching media and materials used in the teaching and learning processes. The pedagogical use in classrooms of digital content or online teaching materials is already a tangible reality that evidences a process of gradual change from traditional textbooks to new digital resources for learning. This article analyzes the pedagogical, socio-communicational and technological characteristics of a sample of commercial platforms of digital educational contents currently existing in Spain destined for Primary Education and in two autonomous communities: Galicia and Valencia. The results presented are part of the research project «The school of digital society: Analysis and proposals for the production and use of educational digital content» (EDU2015-64593-R) carried out by several competitive research groups of various universities, coordinated by the 'Laboratory of Research and New Technologies' (EDULLAB) of the University of La Laguna. To this end, an ad hoc instrument was developed and validated and administered to 13 commercial platforms. The results suggest that there is a wide range of online offer of teaching materials with a variety of formats, although the study has found that most reproduce the format of the traditional book, enriched with online resources..
Between tradition and innovation: the use of textbooks and didactic digital contents in classrooms / Entre la tradición y la innovación: el uso de libros de texto y contenidos didácticos digitales en las aulas

Since 2013, the Italian Minister of Education promoted the use of digital or mixed paper-digital texts in the classroom by means of legislative act (Lex 128/2013). Since then, adoption of the textbook is not mandatory in our country: Italian schools, according to their autonomy, can choose to adopt teaching materials from publishers, Open Educational Resources, or auto-produced texts. The law legitimates the experience of some Italian schools that are innovating the use of textbooks and are involved in a process of auto-production of content (textbooks or DDC, Didactic Digital Content). The article attempts to describe the work of these schools within a network of practice named «Avanguardie Educative». It intends to analyse teachers beliefs and attitudes upon «studying», «textbooks» and «digital texts», to capture innovative aspects, but also to look at difficulties and obstacles along the path of innovation, not always so clear and well defined.

Social media have a special role in today's society and this is being reflected in the development of the professions. Social Education does not escape from this reality and to this we can add the lack of studies on the subject. This article presents part of the analysis carried out as part of a wider investigation into the contribution to Social Education of a blog called "Educablog", which has been running for more than 15 years. The aim is to analyse the contribution of the blog to the identity, professional development and professionalisation of Social Education, from the perspective of professional users. In this research we have opted for a qualitative methodology and we have used the lifeline where we have relied on the use of photographs to gather information. The discourse generated in the development of the dynamic shows significant contributions from “Educablog” in the professionalization, professional identity and professional development of Social Education. In the same way, it has been shown that digital media have significantly accompanied the evolution of Social Education within and outside this object of study.
Nazewnictwo funkcjonujące na językowo-kulturowych pograniczach miast i wsi w dobie globalizacji
Authors: Jelonek Tomasz
Published: January 2024

Głównym celem artykułu jest próba charakterystyki nazewnictwa funkcjonującego na pograniczach miast i wsi w kontekście tendencji globalizacyjnych. Analizie poddano różne typy nazw własnych: antroponimy, toponimy i chrematonimy. Nazwy te pochodzą z gminy Wręczyca Wielka i miejscowości okolicznych w powiecie kłobuckim na północy województwa śląskiego. W pierwszej części artykułu przybliżono specyfikę językowo-kulturowych pogranicz miast i wsi w dobie globalizacji. W kolejnej części tekstu omówiono nazwy własne charakterystyczne dla wspomnianych pogranicz XXI w. Na podstawie analizy stwierdzono między innymi, że mieszkańcy współczesnej wsi funkcjonują w kilku przestrzeniach nazewniczych, które odzwierciedlają przenikanie się trzech typów kultur: wiejskiej, miejskiej i globalnej.
O pochodzeniu pol. budyń
Authors: Stachowski Kamil
Published: January 2024

Wyraz budyń występuje w polszczyźnie od niedawna – około dwustu lat – ale ma on historię dość ciekawą i wciąż nie w pełni zrozumianą. Początkowo pojawiał się w różnych wariantach fonetycznych i graficznych, z których do dzisiaj zachowały się jeszcze dwa. Od tego czasu zmieniał się wciąż jego status w języku i równocześnie znaczenie: początkowo bardzo szerokie, od słodkiego ciasta gotowanego w chuście po farsz do nadziania kury, potem zawężone do dzisiejszego ‛kisielu mlecznego’, a w ostatnich latach znowu rozszerzane na coraz to nowe potrawy. Jego etymologia nie była dotąd badana głębiej, a te propozycje, które pojawiały się w literaturze, wskazują na zupełnie różne kierunki.
MILITARY GEOLOGY: AN AMERICAN TERM OF WORLD WAR I RE-DEFINED FOR THE BRITISH ARMY AT THE END OF WORLD WAR II
Authors: ROSE EDWARD P. F.
Published: January 2024

The term ‘military geology’, translated from German after earlier use in French and Spanish publications, entered the English language via American publications from 1917 onwards, initially after the USA entered World War I. It was widely used in the USA and, in direct or indirect translation, in several European countries additional to Germany and Austria thereafter, but not in the United Kingdom—although military applications of geology had been perceived and utilized by the British Army for much of the previous century. However, the term was used and its scope defined on the basis of operational experience at a meeting in Brussels on 28 February to 1 March 1945 as World War II drew to an end, a meeting seemingly unique for the War in that it comprised five ‘British’ geologist officers of field rank: the South African Major Gordon Lyall Paver, English Major Frederick William Shotton, Australian-born but Canadian-educated English Major John Leonard Farrington, English Squadron Leader John Francis Kirkaldy, and Welsh Major David Ronald Arthur Ponsford. Their purpose was to review wartime use of ‘military geology’ in the British Army, and to make recommendations for a more efficient British military geological service in the future, especially in the Far East after the war in Europe entered its final phase. The meeting generated a four-page closely-typed unpublished ‘Memorandum: Military geology in the British services’ (now preserved in England in the Lapworth Museum at the University of Birmingham and in The National Archives, Kew, near London). This included a very brief summary of the British Army’s deployment of geologists within western Europe, East Africa, the Middle East, North Africa and the Mediterranean region, and India. Those present brought together long experience from all these campaign areas except India (and the Far East in general). That deficiency was made good later in the year, on 7 December 1945, when Eric J. Bradshaw, Superintending Geologist of the Strategic Branch of the Geological Survey of India, completed an 81-page typed unpublished ‘Military geology: Memorandum of post-war policy’ (accessible in England at Birmingham, at Kew, and at the British Geological Survey, Keyworth). This with its 23 pages of appendices records details of wartime work in India and discussions held by the author there and in the United Kingdom following the end of hostilities in Europe on 8 May 1945. It re-defines the scope of ‘military geology’ for British armed forces in terms of water (resources, floods and drainage), stone and miscellaneous mineral resources, soils, engineering projects (reconnaissance, stability and excavations), terrain, ‘photo-geology’ and several miscellaneous applications. The memorandum proposed a grandiose organization of 151 geologist officers plus ancillary staff for British military geology postwar. That organizational scheme was not adopted—but by 1945 the term ‘military geology’ had clearly extended from American to significant British use.
The 2023 New Zealand Ground-Motion Database

This article summarizes the development of the 2023 New Zealand ground-motion database (NZGMDB). A preceding version was formally used as the central ground-motion database in the ground-motion characterization modeling for the 2022 New Zealand (NZ) National Seismic Hazard Model (NSHM) revision. The database contains ground motions for events with a moment magnitude greater than ∼3.0 from the years 2000 to the end of 2022. Several challenges associated with NZ earthquake source metadata are explained, including determination of earthquake location, magnitude, tectonic classification, and finite-fault geometry, among others. The site table leverages the site database developed as a part of the 2022 NZ NSHM revision, and several definitions of source-to-site distance are computed for the propagation path table. The ground-motion quality classification was initially assessed using a neural network. Subsequent waveform quality verification was conducted and additional quality criteria were enforced to ensure a sufficiently high-quality database. Standard processing techniques were applied to the ground motions before intensity measure (IM) calculation. IMs in the database include peak ground acceleration, 5%-damped pseudoacceleration response spectra, smoothed Fourier amplitude spectra, and other cumulative and duration-related metrics. The NZGMDB is publicly available and routinely updated as new and higher quality data become available.
