A Comparison of Different Doses Efficacy of Isobaric Ropivacaine 0.5% in Spinal Anesthesia in Cesarean Section
Authors: Golfam Parisa , Yari Mitra , Prezidend Nahid , Gheitury Bahar , Rezaei Mansour
Published: October 2024

Background: Cesarean delivery is a standard surgical procedure in women. Thus, a practical, affordable, and low-risk anesthetic technique is essential for mother and infant safety. Spinal anesthesia is a popular and efficient technique for anesthesia during cesarean delivery. However, other local anesthesia drugs with negligible side effects should be considered. The most selective medication for this purpose is bupivacaine (marcaine), which creates optimal anesthesia at doses of 10 to 12 mg. Objectives: The most available medicine for spinal anesthesia during cesarean delivery is a 0.5% marine solution. However, ropivacaine for spinal anesthesia can occasionally be accessed as a long-acting amide local anesthetic agent used as an alternative to marcaine during the cesarean delivery. The ropivacaine's advantage over marcaine is its less neurotoxicity and cardiotoxicity, as well as the more stable hemodynamical condition of the patients. So far, no proper therapeutic dose of 0.5% isobaric ropivacaine has been proposed to be used during the cesarean delivery. Any increase in the dose may ensure the block performance, but, by contrast, some side effects may arise, including hypotension, bradycardia, vomiting, and nausea. Herewith, the likelihood of maximum block and most minor side effects was attempted to be assessed at the tiniest doses of this anesthetic agent. Methods: This randomized clinical trial was conducted on C-section candidates. Patients were categorized into three groups receiving 22.5, 25, and 20 mg of the 0.5% isobaric ropivacaine solution. Systolic and diastolic blood pressure, heartbeats, the level of sensational and sympathetic nerve block, duration to reach the maximum motor block, the rate of vasopressors and atropine consumption, rate of vomiting and nausea, the rate of using supplementary drugs, block breakdown, and the patient's satisfaction with the anesthesia were measured and recorded. The collected data were analyzed using IBM SPSS Statistics. Results: No significant difference was found between demographic characteristics. Likewise, there was no significant difference in systolic and diastolic blood pressure, heartbeats, the level of sensational and sympathetic nerve block, duration to reach the maximum motor block, the rate of vasopressors and atropine consumption, rate of vomiting and nausea, and the rate of using supplementary drugs between the three groups. The most significant block breakdown and use of supplementary drugs were found in the first group (20 mg), with a significant difference between the three groups. Conclusions: The three doses used did not result in meaningful differences between the three groups. However, the differences were significant for the block breakdown, with the higher block breakdown and supplementary drug use observed when using 20 mg of the 0.5 ropivacaine solution.

Authors: Farahmand Saeideh , Ghasemi Majid , Basiri Keivan , Ghasemi Ehsan
Published: October 2024

Background: Stroke is one of the most common causes of disability. Spasticity is a common clinical impairment that occurs after a stroke. Spasticity occurs due to changes in the mechanical properties of the muscle and the neural properties following a stroke. Objectives: This study aimed to investigate the effect of Nintendo Wii games on ankle spasticity outcomes in stroke patients. Methods: In this parallel single-blind clinical trial study, 30 patients with stroke were randomly assigned to one of the experimental and control groups. The subjects of both groups received conventional physiotherapy, including stretching of ankle plantar flexor muscles and walking exercises on parallel bars. In addition, the experimental group also received Nintendo Wii games for 30 minutes three times a week for a total of 12 sessions. Clinical outcomes of spasticity and neural properties were evaluated using the Modified Modified Ashworth Scale and H-reflex latency and Hmax/Mmax ratio. All statistical analyses were performed using SPSS version 20. Results: The intragroup results showed that the clinical outcome of spasticity was significantly reduced in the experimental group (P = 0.001). The comparison between the two groups showed no statistically significant difference in clinical outcome and neural properties between the experimental and control groups (P > 0.05). Conclusions: Based on the results, the clinical outcome of spasticity was significantly reduced after the end of the treatment in the Nintendo Wii group. The use of Nintendo Wii can be suggested as a treatment modality alongside the usual treatments to achieve greater and faster effectiveness in patients with stroke.

Published: October 2024

Background: Gram-negative bacteria are the most common infectious bacteria and are life-threatening in burn patients. Phage therapy studies can help the hospital community eliminate these bacterial pathogens. Objectives: This study aimed to evaluate the effects of the isolated bacteriophages from hospital wastewater against Gram-negative pathogenic bacteria and investigate their cytotoxicity on two human skin cell lines. Methods: The bacterial strains were isolated from burn wound infections. Bacteriophages were isolated from the hospital wastewater treatment plant in Isfahan, Iran. Transmission electron microscopy, spot tests, and restriction enzyme digestion were considered for phage identification. Finally, the lactate dehydrogenase (LDH) and tetrazolium-based MTT assays were used to realize the cytotoxicity impacts of the isolated phages. The statistical analysis of cell viability was performed using a two-way analysis of variance (ANOVA). Results: The results showed that among the isolated strains, P. aeruginosa strain NEG_RA1300 (GenBank accession number: MW845642) was sensitive to the isolated phage VbɸPA-1. The TEM results showed a possible viral taxonomy of VbɸPA-1 based on its morphology, which belonged to the Myoviridae (T4-like phages). The MTT and LDH experiments showed no cytotoxicity of VbɸPA-1 on two tested cell lines. Conclusions: Based on the results, the inhibitory effect of isolated phage on P. aeruginosa isolated from burn wounds with no toxic effect on cell lines was very significant. This phage can also be an acceptable selection against burn wound infections.
Symontosis, Ecojustice, and Human-Nonhuman Relations
Authors: Ikhane Peter Aloysius
Published: October 2024

The discourse of human-nonhuman interaction is basically between supporters of the use of nonhuman species for the wellbeing of humans, and advocates of the view that nonhuman species possess intrinsic value. Taking the ecological position, which defends the latter position, as basis, I propose, in this paper, symontosis, as an ontological approach to the discourse. In this vein, I argue that the value of nonhuman species is not to be determined by any calculation of the degree of usefulness to humans. For non-human entities or species could be and has been conceived as having intrinsic worth of their own without necessarily being instrumental to the pleasure of human entities. Unfortunately, in the environment in which written culture first developed the worldview was largely anthropocentric. Everything was made for the pleasure of human entities and was even encouraged to take full dominion of the earth and all its inhabitants. However, since the emergence of affirmative action principles especially, Eco philosophy which teaches that true humanity and ecojustice reside in according nonhuman species and vulnerable entities intrinsic value, the days of arrogating dominion of the ecosystem to human species to the detriment of nonhuman entities are over.
Cultivating Moral and Democratic Values in Nigerian Students
Authors: Unah Jim Ijenwa
Published: October 2024

It is unarguable that the contemporary Nigerian society is enmeshed in a crisis of moral decadence. This research proposal posits that the lack of moral character training, fully integrated into school curriculums, is an important contributory factor to this character bankruptcy in the Nigerian state. On this account, the research proposes that the development of a fiill ethics and character education template from the kindergarten up to the tertiary level will go a long way in addressing the identified problem. In order to achieve this objective, it focuses mainly on a deliberate blend of western and oriental literatures, and a deep understanding of the ethical and character principles with which traditional African societies were able to maintain and sustain peacefiil coexistence. Thus, a four-tier ethics curriculum has been proposed, which will inculcate these values in a systematic way along the lines of the already established school curriculum and planning.

The state or the universal society secures goods that are all-embracing, rooted in the excellences of character that hold the ground for which persons come together. The aim for associating is embodied in education and practical reasonableness that lead persons and communities to realise their end. A body of study about the end, with the best ways of achieving it so that persons and their communities may flourish, becomes a philosophy that expresses the choice for a nation (or state) and its institutions.
Resolving the Problem of Defining Death by Prioritizing the Neurological Criterion
Authors: Turner Barrett H. ,   The National Catholic Bioethics Center
Published: October 2024

One of the major complicating factors when evaluating death by the cardiological criteria is the advent of ventilators and their widespread adoption in recent decades. A person who once was considered dead can now continue take in oxygen and perfuse blood throughout the body. However, use of the neurological criteria instead has its own detractors, with many say the criteria do not fully evaluate brain function. In this article, Turner suggests that the neurological criteria is necessary to avoid the ambiguity brought on by new technologies and that, rather than combining criteria in any way, cardiological criteria should be abandoned entirely in favor of a primary focus on brain death.

The entry of foreign franchise stores and shifts in customer preferences pose significant challenges for Mongolian retail establishments, potentially resulting in a loss of customers, decreased revenue, and even market exit. Consequently, it is essential to explore opportunities for market protection by offering services that align with customer preferences. This research aims to identify the environmental factors of retail stores that influence Mongolian customers' purchasing intentions and to examine whether these factors vary by age and gender. The findings indicate that women tend to focus more on various aspects of the store environment than men, while younger customers demonstrate greater attentiveness than their older counterparts. Additionally, the amount of time and money spent in stores influences customers' priorities during their shopping experiences. Understanding these differential effects can give retailers insights into optimizing the shopping experience and tailoring marketing strategies to enhance customer engagement and drive sales. Based on these insights, it is recommended to enhance the store environment to better accommodate these preferences. The results of the research can be fully utilized in the development of store employees and the ongoing research about the store environment in this field.

Published: October 2024

MoHFW India, WHO, NHS, and CDC suggested imposing lockdown and closing educational institutions with the spread of covid 19 pandemic to reduce the risk of transmitting the disease. Students faced negative mental health symptoms due to unexpected transition from physical to virtual learning, increased screen time, physical distancing, altered habits, rumors through news, print media, social media, and other means. This study focuses on the psychological impact of covid 19 on school and higher education students due to psychosocial factors like physical distancing. 2140 students, mixed gender, in age from 17 years to 25 years (M = 22.73, SD = 6.12) are selected as sample population for the study. Mixed-method approach is used for data collection that include face to face interactions in clinics, Health Questionnaires & Self-Reports, online counseling to assess the stress & depression, Generalized Anxiety Disorder-7, rating scales for Behavior analysis, Warwick-Edinburgh Mental Well-being Scale to assess perceived stress, depression, anxiety, and mental health & well-being, respectively. Analysis of data shows that 42.7% of school and higher education students have either depression or anxiety. 71.7% of students reported poor health and well-being. 36.7% of students reported fear of getting infected by virus, many students were reported with cognitive dissonance in myths and truths about Covid-19. 37.9% of students spend their time on media & social media, including watching TV or reading Covid-19 related news and information on various platforms. About 56.2% students reported with increased use of social media. There was a minor difference between depression and anxiety, as reported by females and male students, however expression of separation fear was slightly higher in male students than female students. Physical distancing and lack of social interaction caused stress, anxiety (GAD) and depression symptoms in students due to imbalances in hormones & neurotransmitters.

Authors: Satchanska G. , Davidova S. , Borisova D.
Published: October 2024

Cheese is essential to the daily human diet. Rich in nutrients such as proteins and carbohydrates, it is the perfect environment for developing microorganisms. The study aimed to screen the antimicrobi¬al resistance of pathogenic microorganisms isolated from imported Bulgarian cheeses. Randomly picked isolates of bacteria and fungi were cultured in selective and differential media. Isolates were identified using the Crystal Gram-positives system, catalase, PYR-test, and API 20 C AUX Candida. Antimicrobial susceptibility screening was performed against 19 antibiotics and three antifungal substances, according to EUCAST-2023 (The European Committee on Antimicrobial Susceptibility Testing). Isolated bacteria were identified as pathogenic Enterococcus durans, two strains of Enterococcus faecalis 1 and 2, and Staphy¬lococcus simulans. Isolated yeasts belong also to pathogenic Candida krusei – four strains, and Candida glabrata – one strain. Only one strain - E. faecalis-2 showed resistance to three antibiotics from the class of Fluoroquinolones (Ciprofloxacin, Levofloxacin, and Norfloxacin) while the other bacterial strains: E. fae¬calis-1, E. durans, and S. simulans, were susceptible to all tested antibiotics. The fungal isolates C. krusei and C. glabrata demonstrated susceptibility to all three tested antifungal drugs.
Understanding and role of gut microbiota on drug response and toxicity
Authors: Seshadri Sriram , Gajjar Devanshi , Joshi Aneri , Bhatia Zeel , Kumar Sunny
Published: October 2024

The gut microbiota affects human health profoundly, and evidence is mounting that it can cause, worsen, or resolve illnesses. Particularly in drug-induced toxicity, its role in diverse toxicological reactions has garnered attention recently. Drugs may interact directly or indirectly, through the gut flora, whether or not they are taken orally, changing the toxicity. Current research focuses mainly on the one-way effect of xenobiotics on the makeup and activities of gut microbes, which leads to altered homeostasis. However, there are two-way interactions between the gut microbiota and xenobiotics, and it is important to consider how the gut microbiota affects xenobiotics, particularly medications. Therefore, we emphasise the microbiome, microbial metabolites, and microbial enzymes in this review to emphasise how the gut microbiota affects medication toxicity. To aid in the identification of micro-biologic targets and processes linked to drug toxicity, we establish connections between medications, the microbiome, microbial enzymes or metabolites, drug metabolites, and host toxicological reactions. In addition, a summary and discussion of contemporary mainstream approaches to controlling medication toxicity by microbiota targeting are provided.

Published: October 2024

Habitat destruction, over exploitation, monoculture are major reasons for loss of primary forests in Himalaya. Tree population, composition and diversity particularly in the temperate Himalaya play a key role in the maintenance of many ecosystem services and natural biogeochemical cycles. The present study explores composition and regeneration status of tree species in a temperate mixed forest in Kyongnosla Alpine Sanctuary, East Sikkim, India. Two sites at an elevation range of 2800–3800 m were selected and 20 plots of 20 m × 20 m for trees, 80 plots of 5 m × 5 m for saplings, and 160 plots of 1 m × 1 m for seedlings were sampled to study the regeneration status. A total of 17 tree species belonging to 9 genera and 8 families were recorded of which Rhododendron was the most dominant genus with maximum number of species. All the phytosociological attributes, such as relative density, abundance and important value index were calculated. The average species richness of adult trees and saplings was 13.5± 0.7 and for seedlings it was 12.5 ± 0.07. The mean density of seedlings was 3609.77 ± 494.39 individuals ha-1, for saplings 1540 ± 113.13 individuals ha-1 and of mature trees 548.75 ± 8.83 individuals ha-1. Total basal area cover ranged from 36.61 to 40.35 m2 ha-1 for trees, from 1.54 to 1.71 m2 ha-1 for saplings. Fair regeneration was observed in 64.72% of total species; good regeneration observed in 17.64% species, 11.76% species exhibited poor regeneration while 5.88% showed no regeneration.
Study Of The Change In Scale For The Sintering Of An Aluminium Alloy Powder By Spark Plasma Sintering
Authors: Moser Mathias , Ariane Mostapha , Buisson Laurent , Augustin Rémi , Sallot Pierre , Bernard Frédéric
Published: October 2024

Spark Plasma Sintering technology is widely used to develop new materials with a fine and controlled microstructure. The key stage in its development (i.e. industrialisation) is the mastering of scale-up. From a SPS perspective, this requires suitable graphite tooling and a sintering cycle that can be applied to large parts. Samples with 60 mm diameter and 10 mm height were sintered from an aluminium alloy powder and characterised to determine the sintering conditions. Then, samples with 170 mm diameter and 15 mm height were sintered. Their metallurgical characterisations, including the numerical simulations of the sintering process, were performed to determine the effects of the scale-up and, at the end, to optimize the sintering conditions to obtain dense and homogeneous samples.
Understanding the Differences in Microstructural Evolution between Additively Manufactured and Conventional 18Ni (300) Maraging Steel upon Post-Processing Heat Treatment
Authors: Sajjadivand Shahrzad , Hartnett Mark , Celikin Mert
Published: October 2024

This study aims to optimise post-processing heat treatment methodology of 18Ni (300) maraging steel manufactured via Laser-based Powder Bed Fusion (PBF-LB). This is achieved by understanding the effect of post-processing heat treatment on the microstructural evolution and mechanical behaviour of PBF-LB 18Ni (300) maraging steel in comparison to conventionally manufactured 18Ni (300) maraging steel. In-depth materials characterisation was carried out using X-ray diffraction (XRD), scanning electron microscopy (SEM). The analysis reveals microstructural variation in PBF-LB 18Ni (300) maraging steel in as-built condition with noticeable hardness changes. However, solutionising at 850 °C, 950 °C, and 1050 °C lead to a more homogenized microstructure and reduced variation in hardness. A comparison of PBF-LB and conventionally manufactured samples reveals similar hardness levels upon post-processing heat treatment.

Authors: Riabov Dmitri , Frisk Karin , Bengtsson Sven
Published: October 2024

This work presents the alloy TS-CF1, a new cobalt-free stainless maraging steel designed specifically for laser-based powder bed fusion using a computer-based alloy design approach. The aim was to create a material that easily prints, while performing similarly to the common maraging variant 18Ni-300. After exploring various compositions, we settled on Fe-13.2Cr-9.1Ni-1.1Al-0.6Mo-0.5Nb-0.23Ti-0.5Mn-0.5Si (wt.%). This composition exhibited excellent printability at 40, and 80 µm layer thicknesses with minimal porosity. The precipitation response was assessed by aging at 500 °C, in both as-built and solutioned conditions. A balanced set of properties was reached after aging between 3 and 6 hours, reaching 530 HV5. Different conditions were microstructurally characterized using EBSD and XRD, showing a mostly martensitic structure with some retained austenite. The tensile strength was between 1560 and 1700 MPa, where higher strength was reached by performing a solutioning heat-treatment. Long-term high temperature exposure tests showed good resilience against precipitate coarsening.

Tomruk üretiminde yapılması gereken zorunlu iş kalemlerinden olan ibreli türlerde kabuk soyma zaman alıcı bir işlemdir. Bu çalışmada, karaçamda farklı ekipmanla kabuk soyma sürelerinin belirlenmesi amaçlanmıştır. Bu amaçla kronometre sıfırlama yöntemiyle zaman ölçme tekniği kullanılarak farklı çaplardaki karaçam tomruklarında kabuk soyma iş-zaman analizi yapılmıştır. Çalışma Ankara Orman İşletme Müdürlüğü Aydos Orman İşletme Şefliği sınırları içinde yer alan 427 ve 451 numaralı bölme-lerde yürütülmüştür. Çalışma sonucunda balta ve motorlu testereye takılan ekipmanla kabuk soyma süreleri belir-lenmiş ve etkinlikleri ortaya konulmuştur. Kabuk soyma aparatının baltaya göre daha kısa sürede ve daha fazla soyma kapasitesi ile daha kullanışlı, pratik ve 2,8 kat daha verimli olduğu belirlenmiştir. Bu bakımdan karaçamda kabuk soyma aparatı kullanımının işgücü, verimlilik ve zaman bakımından avantaj sağladığı sonucuna ulaşılmıştır.

Polyamide is a high-performance synthetic plastic known for its strength, durability, flexibility, chemical resistance, and low cost, making it widely used in engineering, automotive, and electrical. However, the surface and mechanical properties can be further enhanced to meet the growing demands of advanced engineering applications. This study aims to investigate the influence of Al2O3 particles on the hardness of polyamide 6 (PA6). The Al2O3 was mixed with PA6 at weight percentages (wt.%) of 0.3% and 1.5% then were fabricated into composite plates using compression molding and subsequently. As a result, the composites achieved higher microhardness and tensile strength compared to the matrix with increases of 13.3% and 7.3% achieved by incorporating 0.3 wt.% of reinforcement, respectively. This result suggests that Al2O3 has the potential to improve the surface properties and mechanical strength of the matrix material.
Sociosofija ir praktoteorija

Sociosofija straipsnyje vadinu tyrimus, reflektuojančius ontologines ir epistemologines socialinių mokslų teorijų prielaidas. Praktoteorija vadinu akademinę nuostatą iššūkius dabarties mokslo filosofijai priimti susitelkus ne į mokslo žinių, bet mokslo veikų turinį. Šia prasme tiek mokslo filosofija, tiek sociosofija kaip mokslo filosofijos dalis gali vadovautis arba nesivadovauti praktoteorija, kadangi ji yra ne mokslo filosofijos pamatas ar bendroji direktyva, o pasirinktinis tyrimo būdas.Pasiremdamas Alexanderio Wendto, Theodoro Schatzki, Algimanto Valantiejaus, Andy Pickeringo, Bruno Latouro, Zygmunto Baumano, Josepho Rouse’o sociosofiniais tekstais straipsnyje analizuoju, kokios yra praktoteorinės sociosofijos – antidisciplininio naujadaro – ypatybės ir perspektyvos.
Rosyjska propaganda i dezinformacja w branży gier wideo
Authors:   Uniwersytet w Białymstoku, Gawryluk Paweł
Published: October 2024

Niniejszy artykuł jest próbą ukazania pomijanej w literaturze przedmiotu gałęzi wojny informacyjnej jakim jest sektor branży gier wideo. Stale rozwijająca się oraz coraz bardziej dochodowa wraz z wybuchem wojny w Ukrainie stała się pełnoprawnym narzędziem wpływu, z którego do tej pory najbardziej skutecznie korzystały Stany Zjednoczone. Dla Rosji jest to nowy grunt w wojnie informacyjnej, gdyż jej działania wydają się nieusystematyzowane. Propagandowe metody działania są zróżnicowane. Poczynając od subtelnej symboliki, która często trudna jest do wychwycenia dla osób niezaznajomionych z kulturą rosyjską kończąc na siermiężnych wydarzeniach propagandowych w grach online. W kwestii dezinformacji działania FR., szczególnie po 24 lutego 2022 r., koncentrują się na antyukraińskim przekazie gloryfikującym trwającą wojnę w Ukrainie, który rozprowadzany jest przez rosyjskich agentów wywiadu oraz osoby należące do Grupy Wagnera. Operowanie w tym sektorze wydaje się specyficzne, gdyż gracze jako zbiorowość są grupą zróżnicowaną, mocno emocjonalną, w której dominują osoby młode oraz nastawione na konsumpcje dzieł kultury, dzięki czemu ich podatność na manipulacje jest odpowiednio większa od osób dorosłych. Działania branży gier w tej sprawie w najlepszym wypadku koncentrują się na odcięciu od rosyjskiego rynku, natomiast w najgorszym na kompletnym zignorowaniu problemu. FR. przez lata zwyczajnie ignorowała możliwości soft power, jakie dają gry wideo, a jej działania w tym kierunku były nieskuteczne i nieprzemyślane. Dopiero po zmierzeniu się z licznymi sankcjami w związku z wojną w Ukrainie, opracowano kompleksowy plan zdominowania branży gier wideo, który znajduje się pod znakiem zapytania.
Gra z przeszłością: czy dekolonizacja dziejów Ukrainy ma sens?
Authors:   Centrum Mieroszewskiego, Warszawa, Korolov Gennadii
Published: October 2024

Współczesne podejście do dekolonizacji jako tematu obszernych dyskusji intelektualnych stanowi ogromny problem i jest zaśmiecone wieloma uprzedzeniami. W wielu przypadkach kwestia ta wynika z upolitycznienia i ideologicznych wezwań do dekolonizacji historii Europy Środkowo-Wschodniej, które nie mają nic wspólnego z metodologiczną lub akademicką dyskusją. Zazwyczaj pojęcie Europa Środkowo-Wschodnia jest zastępowane przez Rosję, Europę Wschodnią lub ideologiczny termin Eurazja. Ogólnie rzecz biorąc, retoryka dekolonizacji opiera się na twierdzeniu, że Rosja i Związek Sowiecki były imperiami kolonialnymi.
Historiografia Szida Kartli – Osetii Południowej; historyczny spór o terytorium między Gruzinami a Osetyjczykami
Authors:   Uniwersytet Warszawski, Stawujak Tadeusz
Published: October 2024

Celem eseju jest skonfrontowanie narracji gruzińskiej i osetyjskiej, dotyczących tożsamości historycznej tzw. Osetii Południowej, formalnie należącej do regionu Szida Kartli. Narracja, dotycząca tożsamości regionalnej, jest wykorzystywana przez Gruzinów i Osetyjczyków do osiągania swoich celów politycznych. Przedstawiona jest historia relacji gruzińsko-osetyjskich, przykłady dziedzictwa historycznego i kulturowego obu narodów, oraz wpływ Rosji na kształtowanie się stosunków międzyetnicznych i zmian politycznych. Zachodzące w Szida Kartli procesy migracyjne i polityczne (przesiedlenia, wojny, polityka narodowościowa Rosji) wpłynęły na złożoność problemów w relacjach między Gruzinami a Osetyjczykami. Powyższe aspekty sprawiły, że polaryzacja między dwoma narodami jest bardzo trudna do pokonania. Zważywszy na obecną sytuację polityczną na obszarze postradzieckim, kwestia przynależności tzw. Osetii Południowej jest tematem aktualnym.
Propaganda sowiecka w świetle raportów i korespondencji dyplomatów polskich 1927-1932
Authors:   Archiwum Główne Akt Dawnych Warszawa, Bartoszewicz Henryk
Published: October 2024

Przedmiotem artykułu jest obraz propagandy sowieckiej ukazany w raportach i korespondencji dyplomatów polskich w latach 1927-1932. Polem doświadczalnym systemu propagandy budowanej w Rosji po bolszewickim zamachu w listopadzie 1917 r. stała się wojna z Polską. Doświadczenia wojny lat 1919-1920 spowodowały, że władze w Warszawie z uwagą śledziły działalność sowieckich akcji propagandowych. Antypolskie akcje propagandowe nasilały się lub słabły w zależności od stanu stosunków między Warszawą a Moskwą, ale nigdy Kreml nie zrezygnował z działań skierowanych przeciwko Polsce. Polska była państwem z największą zaciekłością atakowanym przez sowiecką propagandę. Nasilenie sowieckiej propagandy antypolskiej nastąpiło po zamachu majowym 1926 r. Powrót do władzy Józefa Piłsudskiego, znienawidzonego na Kremlu zwycięzcy wojny 1920 r., nie był dla Sowietów obojętny. Strona polska zdawała sobie sprawę z zagrożeń z tego wynikających. Poselstwo polskie i konsulaty w ZSRR nie tylko informowały Ministerstwo Spraw Zagranicznych o sowieckich akcjach propagandowych, ale podejmowały także przeciwdziałania. Mianowany 10 grudnia 1926 r. posłem w Moskwie Stanisław Patek we współpracy z kierującymi konsulatami polskimi w Związku Sowieckim zorganizował system gromadzenia, rejestrowania antypolskich działań sowieckich, w tym propagandowych, o których konsulaty informowały poselstwo polskie w Moskwie i Ministerstwo Spraw Zagranicznych w Warszawie. Placówki gromadziły także materiały niezbędne do przeciwdziałania sowieckim akcjom propagandowym wymierzonym przeciwko Polsce.
Le polyamour au Canada : étude d’une structure familiale émergente
Authors: Boyd John-Paul
Published: October 2024

En juin 2016, l’Institut canadien de recherche sur le droit et la famille a commencé à s’intéresser aux diverses perceptions concernant la notion de polyamour au Canada. Le projet n’en est encore qu’à mi-parcours, mais les données colligées jusqu’ici pourraient avoir une incidence importante sur la législation et les politiques au cours des prochaines décennies, suivant l’évolution constante de la notion de famille. Le terme polyamour est formé du préfixe grec poly (qui signifie « plusieurs » ou « en abondance ») et du mot d’origine latine amour. En accord avec cette étymologie, les polyamoureux vivent donc plusieurs relations intimes simultanées, ou manifestent une telle préférence. Certains polyamoureux sont engagés dans des relations amoureuses stables à long terme impliquant deux ou plusieurs autres partenaires, alors que d’autres entretiennent simultanément plusieurs relations plus ou moins durables ou engagées. Dans certains cas, les relations simultanées se vivent à court terme ou sur une base purement sexuelle, et parfois elles sont plus durables et se caractérisent par un engagement affectif plus marqué. Polyamour Pratique ou condition se caractérisant par la participation à plusieurs relations intimes simultanément, sans motivation religieuse ni obligation découlant du mariage. Polygamie Pratique ou condition se caractérisant par le fait d’avoir plusieurs époux ou épouses simultanément (habituellement des femmes), la plupart du temps pour des motifs religieux.
ALFABETIZAÇÃO CARTOGRÁFICA
Authors: Silva Julio César Felix da , Gomes Edvânia Torres Aguiar
Published: October 2024

O processo de ensino/aprendizagem dos conceitos espaciais e da sua representação cartográfica não é uma tarefa fácil para os professores nos Anos Iniciais do Ensino Fundamental, pois o professor deve assimilar e compreender os conceitos geográficos e os fundamentos onde estão calcadas as primeiras noções relacionadas à cartografia escolar. Somam-se a isso as limitações da formação dos professores no tocante a conhecimentos que os habilitem a desenvolver procedimentos metodológicos claros e completos voltados para o processo de alfabetização cartográfica, implicando fragilidades no ensino/aprendizagem da cartografia escolar. Diante desse contexto, a ideia desse artigo é socializar uma prática geográfica desenvolvida em sala de aula no âmbito da alfabetização cartográfica, realizada com uma turma multisseriada do 1º ao 3º Ano e uma turma de 4º ano do Ensino Fundamental na Escola Ambiental no município de Lajedo – PE. Por esse motivo, o presente texto faz uma breve abordagem teórica sobre a linguagem e alfabetização cartográfica, a qual orientou a proposição da prática pedagógica presente de forma pormenorizada na segunda parte do texto.
