Lietuvos gyventojų nuostatos dėl Europos Sąjungos: tarp entuziazmo ir skepticizmo
Authors: Garškaitė-Antonowicz Rosita
Published: February 2025

This article examines how Lithuanian citizens perceive and evaluate the European Union and Lithuania’s membership in it. While quantitative data from public opinion surveys are overwhelmingly positive, and Eurosceptic political actors are marginal, analysis of qualitative data collected through in-depth and semi-structured interviews reveals a more nuanced picture. Attitudes of a large proportion of informants are multidimensional and ambivalent. The thematic and rhetorical analysis of the interviews with the 80 research participants demonstrates key meanings associated with European integration. Most salient of them are rooted in the existential needs of well-being and security. Criticism towards the EU is based on abstract and concrete political grievances, rejection of the idea of limited sovereignty, feelings of inferiority, and anxiety about value change. The paper also argues that, despite their criticism, informants should not be labelled as Eurosceptics. In the Lithuanian case much more productive strategy is to identify various subcategories of support, ranging from unconditional enthusiasm to cautious ambivalence.
Аналіз розвитку атомної енергетики як соціотехнічної системи
Authors: Іванова Г. Т.
Published: February 2025

Стаття розглядає атомну енергетику як складну соціотехнічну систему, де важливо враховувати взаємодію технологій, соціальних процесів, ідеалів та цінностей суспільства з метою забезпечення ефективного та безпечного функціонування. Атомна енергетика залишається однією з ключових галузей сучасної енергетики, але її використання вимагає комплексного підходу та урахування широкого спектра аспектів, включаючи соціальні, гуманітарні та екологічні чинники. Особлива увага до цієї теми виникає у зв’язку з не-обхідністю забезпечення безпеки та ефективності функціонування атомної енергетики в умовах зростаючих вимог до сталого розвитку та збереження навколишнього середо-вища. В сучасному світі, де енергетика відіграє ключову роль у розвитку суспільства і стає джерелом можливих ризиків, важливо розглядати атомну енергетику як комплексну систему, взаємодія якої залежить від технологій, соціальних процесів, ідеалів та ціннос-тей суспільства. Шляхом аналізу різних підходів до концепції «соціотехнічна система» автори статті виявили основні компоненти атомної енергетики як соціотехнічної системи. Аналіз літератури показав, що соціотехнічна система включає взаємодію інституцій, технологій, соціальних процесів, ідеалів та цінностей суспільства, які взаємопов’язані і впливають один на одного, забезпечуючи ефективне та безпечне функціонування атомної енергетики. Основні результати дослідження полягають в узагальненні наявних підходів до атомної енергетики та виділенні ключових компонентів цієї системи. Висновки статті стосуються осмислення рекомендацій щодо поліпшення безпеки та управління ядерною енергетикою, а також підкреслення важливості розуміння та підтримки громадськістю переваг і ризиків цієї галузі. Одним із ключових висновків є необхідність моніторингу громадського занепокоєння щодо радіаційної небезпеки, проблем управління відходами, пов’язаних з ядерною енергетикою та розширення просвітницької діяльності й інформу-вання про переваги і ризики галузі.

Automatic Construction of Information Extraction Rules for News Websites
Authors: Dubovitskii Sergei Sergeevich , Bedrin Pavel Alexandrovich , Yatskov Alexander Konstantinovich , Varlamov Maxim Igorevich
Published: February 2025

This paper presents a method for the automatic generation of information extraction rules (sitemaps) for news websites. The proposed approach generates a sitemap based on a set of news pages from a single site, enabling attribute extraction from arbitrary news pages on that site. The method is based on applying a fine-tuned neural network model, MarkupLM, to extract information from web pages. This approach generalizes the model’s predictions at the site level, creating universal rules for attribute extraction. Experimental results show that using sitemaps generated with the fine-tuned model surpasses both existing open-source tools and the fine-tuned MarkupLM applied at the individual page level. The developed method can be extended to other domains if relevant data for model fine-tuning is available.

Authors: Shcheglov Georgy Alexandrovich , Zhdanova Kristina Alexandrovna , Zhumaev Zaynulla Serikovich , Kamenev Nikita Dmitrievich
Published: February 2025

The paper shows that a pressing problem in the development of nanosatellites is the lack of open software for on-board computing devices and “smart” payloads. The development of an open software package for centralized management of target terminal devices of nanosatellites based on microservice architecture is considered. The advantages of using this approach when creating a software package are shown. It is proposed to use a nanosatellite simulation model for operational debugging and testing of the software package. The authors of the work present the structure of the software complex and show the place of the simulation model in it. The work is a detailed review of the UEMKA software package developed by the authors.

Published: February 2025

U jednom od najstarijih arhiva u Republici Hrvatskoj u Nadbiskupskom arhivu u Splitu (Arhiv ustanova ve- zanih uz splitsku katedralu) čuva se vrijedna građa koja svjedoči o bogatoj kulturnoj i pisanoj baštini jednoga naroda. Među tom građom nalaze se i Štenja iz splitske katedrale – životopisi svetaca i druge liturgijske knjige, stara zbirka od 33 knjižice. Veliki dio tih knjižica čine štenja (Štenja svetaca), to jest kratki životopisi svetaca koji su se čitali prilikom liturgijskih obreda i bili u uporabi svećenstva u katedrali. Cijela je zbirka nastajala u dugom periodu (od 1678. pa sve do 1908. godine), a Štenja svetaca (njih 11) datiraju iz 18. stoljeća. Tijek jezičnih mijenja najbolje se očituje na temelju povijesnih spisa, dokumenata, bilješki i književnih djela te ostalih tekstova koji mogu pomoći pri jezičnoj analizi. U ovom će se radu jezično analizirati štenje pod brojem 4 s naslovom Poçimÿe stenÿe od çudnovatoga prikaɀanÿa prihodechiega Duha Sfetoga meù Apostole, i Vçenike Isukarstove. Iako kod većega broja zapisanih štenja autor nije poznat, to u ovom tekstu nije slučaj. Autor se potpisao (Paulus Covacich Presbyter) te naveo godinu kada je tekst nastao (MDCCLXXII). Nakon sažetih podataka o samome zapisu, donijet će se pojedine značajke vezane za grafiju, pravopis i jezik toga teksta.

Iako je čakavština u Splitu u 18. stoljeću već odavno zamrla i prepustila mjesto štokavskom jezičnom izrazu, pretpostavka je da bi se ipak ponegdje u tekstu mogle osjetiti i čakavske jezične crte koje će posvjedočiti o postojanju splitske čakavske riči, odnosno da bi se u podlozi ovoga teksta mogao osjetiti čakavski (stariji) jezični sloj. Zbog velike rasprostranjenosti štokavskoga narječja koje je uslijedilo i „zavladalo” čakavskim prostorom, jasno je da će u tekstu u pojedinim segmentima gramatičke odrednice zasigurno svjedočiti i o vrlo jakom štokavskom (novijem) jezičnom sloju. Neizostavno će biti i preklapanje tih dvaju slojeva, kako na kojoj jezičnoj razini. Zasigurno će biti zanimljivo to jezičnom analizom dokazati. Na temelju detaljnje analize (fonološke, morfološke, sintaktičke i leksičke) te pregleda grafije i pravopisa zadanoga štenja iz 18. stoljeća, pokazat će se prisustvo različitih jezičnih slojeva, odnosno prisustvo čakavskih (starijih) i štokavskih (novijih) jezičnih odrednica. Tekst ove knjižice ima iznimnu povijesnu, jezičnu, dokumentarnu i znanstvenu vrijednost i zasigurno će, kao takav, posvjedočiti o bogatoj splitskoj pisanoj baštini.

Update on community acquired pneumonia in African children
Authors: Washaya Norbertta , Gray Diane
Published: February 2025

Recent medical advances have led to a drop in the global incidence of pneumonia. Despite this global drop, pneumonia remains the number one cause of childhood mortality outside the neonatal period, especially in low-to-middle income countries. The purpose of this review is to give an update on the causes, diagnosis, management, and prevention of community acquired pneumonia (CAP) in African children.
Due to increased immunisation coverage, viruses have become the most common cause of CAP (respiratory syncytial virus being the most common virus), while staphylococcus aureus and non-typeable Haemophilus influenzae are the most common causes in fully immunised children.
Extensive investigations are not warranted in most cases, as a result, investigations to be carried out will be dependent upon the clinical condition and local protocol. In light of the COVID-19 pandemic all cases of CAP must be screened for COVID-19.
Antimicrobial treatment is determined by, clinical severity, local antibiotic resistance patterns, presence of complications, the causative organism, and local protocols. Broad-spectrum antibiotics such as amoxicillin-clavulanic acid or a 2nd or 3rd generation cephalosporin are normally sufficient. Special attention needs to be paid to immunocompromised children as well as those with sickle cell disease, as additional pharmacological cover is recommended.
Notwithstanding the significant burden posed by CAP in low-to-middle income countries, there remains a paucity of data on CAP from Africa, therefore, it is of paramount importance that further epidemiological data be collected from African countries to optimise the understanding, prevention and management of CAP in Africa.
A case of cutaneous histoplasmosis in a child with HIV infection
Authors: Lochan Harsha , Gxolo Fungiwe
Published: February 2025

Histoplasmosis is an endemic fungal infection that can infect both immunocompetent and immunocompromised individuals. Due to the non-specific clinical symptoms, it can often be misdiagnosed as a more commonly occurring infection such as tuberculosis. In this case report we describe the presentation of a young girl, recently diagnosed with HIV infection, with extensive facial lesions that were found to be positive for histoplasmosis on molecular testing. She responded well to antifungal therapy.
A case of a four-year-old with helminthiasis complicated by intestinal obstruction and atrial trigeminy
Authors: Adebayo Bosede , Lawal Taiwo , Oni Temitope , Oladokun Regina
Published: February 2025

A child presented with a 4-day history of abdominal pain and distension, constipation, and bilious vomiting. The diagnosis of intestinal obstruction secondary to multiple worm boluses in the intestinal lumen was established during laparotomy. Intraoperatively, he suffered a cardiac arrest which was preceded by an episode of near-fatal arrhythmia. The arrythmia was thought to be a complication of eosinophilic myocarditis which had hitherto not been widely documented in children with heavy worm infestation. As children bear a significant burden of helminthiasis, there is a need to intensify public deworming programme.
Determinants of human papillomavirus (HPV) vaccine hesitancy in sub-Saharan Africa: A systematic review
Authors: Omayo L N , Malande O O , Musyoki A M , Hoffman P X , Adamu V E
Published: February 2025

Background: Vaccine hesitancy is a major public health issue that has negatively impacted vaccine uptake in sub-Saharan Africa (SSA). The reasons why individuals hesitate or refuse to vaccinate are variable and factors contributing to vaccine hesitancy are not well outlined. This review, therefore, aims to identify and describe the determinants of HPV vaccine hesitancy in SSA.Methods: A systematic search was conducted across four electronic databases (PubMed, Scopus, CINAHL and Web of Science) from 2007 until October 2021 and updated in January 2022. Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses, 13 studies were eligible and were included in the analysis. Data extraction and synthesis were guided by the Health Belief Model. Quality assessment was performed using the NIH and CASP quality assessment tools.Results: The most frequently reported factors influencing HPV vaccine hesitancy included concerns about side effects and infertility; limited knowledge of HPV vaccine, HPV infection, and cervical cancer; lack of awareness of vaccination opportunities; mistrust of health workers, health authorities, and new vaccines; influence by caregivers, peers, community members or respected members of the society and religious and cultural factors. Other factors included accessibility issues (roads in poor condition, transport costs), adolescent absenteeism on vaccination day and dropping out of school.Conclusion: To reduce hesitancy and improve HPV vaccination coverage, vaccination programs need to develop and implement inclusive and context-specific strategies to enhance vaccine confidence, alleviate concerns, engage, and provide appropriate information to stakeholders involved in HPV vaccination, and dispel rumours and misinformation. The capacity of teachers and healthcare providers must be reinforced to equip them with knowledge about HPV vaccines, improve their interpersonal communication skills so that they can be better advocates for the vaccine within their communities.
The challenges of treating HIV-infected adolescents
Authors: Bakeera-Kitaka Sabrina
Published: February 2025

Adolescents and young people represent a growing share of people living with HIV worldwide. In 2020 alone, 410,000 [194,000-690,000] young people between the ages of 10 to 24 were newly infected with HIV, of whom 150,000 [44,000-310,000] were adolescents between the ages of 10 and 19. To compound this, most recent data indicate that only 25 per cent of adolescent girls and 17 per cent of adolescent boys aged 15-19 in Eastern and Southern Africa – the region most affected by HIV – have been tested for HIV in the past 12 months and received the result of the last test. The testing rates in West and Central Africa and South Asia are even lower. If current trends continue, hundreds of thousands more will become HIV-positive in the coming years, and without knowing their status, adolescents will miss out on life-saving treatment. Additionally, a large population of children infected with HIV perinatally over the last decade are growing into adolescence.

Authors: Asante A , Rabie H , Goussard P , Gie A , Frigati L
Published: February 2025

Empyema necessitans is a rare complication of pneumonia in which pus formed in the pleural cavity extends into the surrounding tissue. In children it is mostly caused by Mycobacterium tuberculosis, but other bacterial organisms are implicated occasionally. Early diagnosis through appropriate imaging, cultures and molecular diagnostic tests of samples taken from the lesion is recommended. Outcome is good provided appropriate medical and surgical treatment are provided.
Upper airway obstruction in a Nigerian girl with Diphtheria: Could blind nasotracheal intubation be the minimally invasive alternative treatment in a resource-constrained setting?
Authors: Hamza Abdulhakeem , Adebayo Bosede , Zakari Ayuba , Abdullahi Adamu
Published: February 2025

Managing upper airway obstruction in patients with diphtheria can be challenging. In a resource-constrained setting with no Intensive Care Units, blind nasotracheal intubation could be lifesaving. We report an eight-year-old girl who presented with a sore throat, fever, neck swelling and severe pallor. Following the commencement of blood transfusion, she developed respiratory distress associated with restlessness, stridor and gasping for air. Emergency nasotracheal intubation resulted in resolution of the respiratory distress and other symptoms. While evaluating a child with diphtheria, the sudden emergence of restlessness and respiratory distress may signal upper airway obstruction. Urgent blind nasotracheal intubation may be lifesaving.
Blood cultures in paediatrics: clinical indications to obtain a blood culture
Authors: Harrison Michael , Bamford Colleen , Dowling Wentzel , Lochan Harsha , Tootla Hafsah Deepa
Published: February 2025

Globally there is no consensus on the ideal set of indications for obtaining a blood culture in paediatric and neonatal practice. In sub-Saharan Africa, where paediatric sepsis is associated with worse outcomes than other regions, early and accurate detection of bacteraemia is particularly important. However, use of blood culture in sub-Saharan Africa is complicated by resource limitation, variable availability of microbiological laboratory services, and prevalence of coinfections such as malaria, tuberculosis and HIV. Additional factors, such as different vaccination profiles and disease severity at presentation, limit generalisability of approaches developed for use in high-income countries. We review the literature on clinical indications for blood cultures in paediatric and neonatal practice, including current practices from sub-Saharan Africa and low-middle income countries, and propose a simple, practical set of clinical indications for blood culture in paediatric and neonatal practice in this setting.
Zero-dose or under immunized: Where should the emphasis lie?

Vaccine preventable diseases (VPD) pose significant morbidity and mortality globally. Two years after the endorsement of Immunization Agenda 2030 (IA2030), the number of children not fully vaccinated increased from 19 million pre-COVID-19 to 25 million post-COVID, with 72% (18.2 million) of these labelled as zero-dose, i. e those who did not receive DPT 1 vaccine. While children who do not initiate vaccination early (zero-dose) may be at a greater risk of missing subsequent vaccinations, we most respectfully suggest that this term zero-dose may be problematic, lending itself to misconceptions among policy makers and health professionals. Firstly, zero-dose is currently set at six weeks DPT1 vaccination point and not at birth for children 12-23 months of age. Secondly, assessing zero-dose in children 12 to 23 months of age, delays corrective or remedial action because by month 12, the children have missed key vaccines before they are flagged as zero dosers. Thirdly, in poor settings, many children who initiate vaccination do not complete the schedule, with DPT1 coverage always higher than measles vaccine coverage. Additionally, the children in poor countries who miss the first DPT dose face similar challenges and deprivations and barriers as those who fail to complete their immunization schedule. The problems of poverty, inability to fully access immunization services, hesitant caregivers and poorly equipped immunization programs affect all children across sub–Saharan Africa and other poor countries. This review seeks to discuss the importance of looking at the entire recommended immunization schedule over and above highlighting those who miss DPT1 alone and proposes that “under-immunized” children as an entity be equally emphasized as “zero dose” children in low- and middle-income countries to ensure that adequate attention is given to both vulnerable groups.
The effect of economic complexity and relatedness on the economic growth of brazilian microregions ♦
Authors: SMOLSKI Felipe Micail da Silva , RUFFONI Janaina , MASCARINI Suelene
Published: February 2025

Abstract This paper examines the effects of economic complexity and relatedness (proximity of productive knowledge) on the economic growth of Brazilian microregions. The perspective of economic complexity suggests that countries advancing in terms of productive sophistication and relatedness tend to achieve higher levels of income and economic growth. Additionally, regional-level analyses have consistently contributed to the growing body of evidence supporting this assertion. We employed dynamic spatial econometric models (SDM, SDGMM-SYS, and SDGMM-DIF) across 558 Brazilian microregions, utilizing employment data for 59 economic activities from 2002 to 2020. Our findings suggest that, firstly, an increased level of economic complexity in microregions is associated with a higher GDP per capita. Secondly, the density around industries (relatedness density) positively affects GDP per capita. Thirdly, and most importantly, our analysis reveals that economic complexity has unequal effects on the economic growth of microregions when examining distinct major Brazilian regions, particularly concerning per capita GDP. A lack of empirical evidence exists regarding the effects of relatedness and economic complexity on regional growth in Brazil, with issues of endogeneity and spatial dependence often overlooked. Our study addresses this gap by providing new insights into the effects of economic complexity and relatedness on regional growth, as well as the varying effects among Brazilian regions. Understanding these processes aids in formulating strategic interventions to promote economic complexity, relatedness, and regional economic growth.
Global Politics of Welsh Patagonia: Settler Colonialism from the Margins
Authors: Taylor Lucy
Published: February 2025

Inspired by decolonial thinking, this book challenges romantic images of Y Wladfa, the Welsh Patagonian settlement founded in 1865. Drawing on archival sources written in Spanish, Welsh and English, it exposes the complex human relationships of this settler colony, and in particular disrupts the myth of Welsh–Indigenous friendship by foregrounding Indigenous experience and revealing less familiar accounts in the record. A newly-developed framework applies three logics – possession, racialization/barbarisation, and assimilation – to make sense of settler colonialism in Patagonia and to debate Wales’s complex position as both colonised and coloniser. A new analysis of contemporary cultural products (television, film, textbooks) further demonstrates how the romantic view continues to shape racial stereotypes today, concluding that such settler origin countries as Wales are vital sites of decolonial debate.

Published: February 2025

Este libro de texto pretende implementar y potenciar estrategias de aprendizaje que favorezcan el proceso de adquisición básica de la lengua española escrita como segunda lengua para las personas sordas. La creación de este libro de texto es el resultado del ejercicio pedagógico practicado con alumnos con discapacidad auditiva de un colegio distrital en Bogotá (Colombia), en el que se han tomado diferentes aspectos del plan de estudios y la metodología de enseñanza, con ciertas flexibilizaciones y adecuaciones, para que sus contenidos en modalidad escrita puedan adecuarse más al estilo cognitivo de este grupo poblacional. Sus contenidos y metodología están diseñados mediante apoyo visual de imágenes que ayudan al estudiante a relacionar lo escrito con su referente, explicaciones que van avanzando según el nivel de dificultad de la lección y diferentes ejercicios y actividades presentados de una manera agradable y sencilla, con el objetivo de que el desarrollo y avance de la lengua escrita en español sea accesible y práctico. Cada unidad se presenta con un título bajo el cual se organiza el tema de la lectura inicial, el vocabulario, los aspectos gramaticales más importantes, las actividades prácticas y las lecturas complementarias. A su vez, este libro está ligado a un hilo conductor que lleva al estudiante sordo a avanzar y profundizar en el conocimiento sobre lo que le rodea, de manera que entienda, no solo el funcionamiento esencial de la lengua, sino también todo lo inherente a su entorno social y cultural más cotidiano. Esto hace que este libro de texto sea también un proceso de inmersión, acceso y apropiación de la ciudad que favorezca el ejercicio de los derechos de las personas con discapacidad auditiva.

Published: February 2025

Objective. To analyze the long-term outcomes in patients with hypertrophic cardiomyopathy (HCM) after ethanol septal ablation (ESA). Material and methods. There were 25 ESA procedures in patients with HCM and left ventricular outflow tract (LVOT) obstruction between January 2018 and September 2022. Mean age of patients was 61 [43; 80] years, women prevailed (60%). All patients had HCM with LVOT obstruction and peak pressure gradient ≥50 mm Hg. Before ESA, patients underwent balloon occlusion of septal branch, and intervention was performed only when peak pressure gradient decreased by 50% or more. Results. One patient died from tumor of the frontal and temporal lobe. Another patient experienced non-fatal stroke. There were no repeated interventions on LVOT, myocardial infarctions or pacemaker implantations. Survey revealed that 5 (24%) patients had recurrence of angina pectoris, 11 (52%) — shortness of breath, 8 (38%) — fatigue despite low peak pressure gradient (<35 mm Hg) after ESA. Conclusion. Taking into account the long-term results in this study (22 [7; 40] months), we can emphasize high effectiveness and safety of ESA in these patients. Together with literature data, it is a serious argument in favor of this technology in various hospitals engaged in high-tech medical care for patients with HCM.

Objective. To develop safe ex vivo coronary angiography approach immediately before heart implantation. Material and methods. A reservoir-container was developed to place a heart in anatomical position for subsequent coronary angiography. 3D STL drawing was prepared with subsequent 3D printing. The next stage was analysis of laboratory animals with development of novel selective coronary angiography method and series of standard high-quality angiograms. A total of 6 experiments were carried out. Coronary angiography was performed using a General Electric OEC 9900 Elice C-arm. Results. We developed a non-contrast reservoir-container for donor heart positioning and standard angiography. Ex vivo coronary angiography using pig hearts visualized all coronary arteries in standard projections. Conclusion. Considering older age of donors and features of organ donation system in our country, donor heart coronary status assessment is beyond doubt. We experimentally confirmed safety of ex vivo coronary angiography of a donor heart. A clinical trial and implementation are planned in the future.

Sex cord tumor with annular tubules is a rare type of ovarian tumor, which seems to arise from Sertoli cells. Most tumors are associated with Peutz—Jeghers syndrome and have a benign course and favorable prognosis; however, about 20% of sporadic sex cord tumors with annular tubules have a high risk of developing metastases. We present a case report about 18-year-old patient who presented with irregular menstruation and abdominal pain. Based on the histological features and immunohistochemical results, the diagnosis of a sex cord tumor with annular tubules was confirmed.

Authors: Van der Walt Janke , Plastow Nicola , Unger Marianne
Published: February 2025

Abstract: There is a high prevalence of motor skill impairment among pre-school children in rural low socio-economic areas. While therapy input is paramount, resources are limited. This Delphi study aims to determine what the components would be of a feasible, cost-effective motor skill intervention for pre-school children in a rural, low socio-economic area of South Africa.A three-round Delphi study was conducted with experts in the field, including therapists, kinderkineticists and teachers. The first round investigated demographic details of participants and agreement of participants on role players, structure and content of an intervention. Subsequent rounds' questions followed up on participants' comments and areas of dissent. Agreement was calculated at 75% or mean >4.Outcomes suggest that a school-based, small-group programme, facilitated by the teaching team, but with clear guidelines, support and advice from therapists should be feasible in a low-income rural context. Inclusivity of intervention groups and aim-formulation proved to be controversial issues that need further investigation.The results from this study helped develop a guide for motor skill intervention for pre-school children in low socio-economic and rural areas

Introduction. The incidence of implant-related complications exceeds 50%. Poor reduction and incorrect implant position significantly increase the risk of mechanical complications and the frequency of unsatisfactory treatment outcomes.
Aim of the study: to evaluate fragment positions after intramedullary nailing of proximal femur fractures using the developed radiological criteria for assessing the quality of reduction and to determine the association between the quality of reduction, implant position and fracture type.
Materials and methods. In a retrospective single-center study we analyzed the primary X-rays of 108 patients with type 31A fractures. Radiological criteria were defined. According to them the position of the fragments and implants was considered satisfactory if the value of the neck-diaphyseal angle was more than 125°, anteversion did not exceed 20°, medial diastasis was not more than 10 mm, and there were no negative medial support, no femoral neck lengthening of more than 10 mm compared with the healthy side, and no penetration of the blade into the joint. Patients were divided into three groups according to the fracture type. We analyzed and compared the proportions of satisfactory and unsatisfactory radiological results within the groups and between them.
Results. Satisfactory reduction was found in 83 patients (76.9%) out of 108, unsatisfactory - in 25 patients (23.1%), and 16 patients (14.8%) had incorrect implant position. Patients with type 31A1 fractures were 3.5 times less likely to have an unsatisfactory reduction than patients with type 31A2 fractures (OR 3.511, 95% CI 1.202-10.261) and 6.7 times less likely to have an unsatisfactory reduction than patients with type 31A3 fractures (OR 6.714, 95% CI 1.685-26.752). The probability of incorrect implant position was 6 times higher in type 31A3 fractures than in type 31A1 fractures (OR 6,000, 95% CI 1,410-25,528).
Conclusion. It is necessary to pay increased attention to the quality of the achieved reduction, implant selection, technical features of A2 and A3 fractures fixation, improvement of preoperative planning algorithms, as well as elaboration of criteria for intraoperative radiological assessment of the quality of restoration of the proximal femur anatomy in order to improve the quality of surgical treatment
Ocean Microseisms Recorded by the Cuban Seismic Network: Time Variation, Spectral Features, and Source Directionality Characteristics

Ocean microseisms, caused by ocean gravity waves, dominate the ambient seismic wavefield from 1 to 20 s. Microseisms can be categorized as primary microseisms (PM) from 10 to 20 s and secondary microseisms (SM) from 1 to 10 s. Although the observations were well established, the characteristics of ocean microseisms in Cuba have never been explored, and those in semi-enclosed seas have been investigated to a limited extent compared with open oceans. Therefore, we analyzed broadband seismic data at 13 stations in Cuba from 2020 to 2021 to reveal the excitation. First, we revealed the main spectral features for the peaks of PM and SM. Second, we estimated the location of the sources that contribute to generating SM at three period ranges: 1–2 s, 2–4 s, and 4–8 s. For this purpose, we conducted polarization analysis at each seismic station, focusing on both Rayleigh and P waves. Our results reveal a broad SM peak with a dominant period between 2.9 and 4.1 s at all stations. A more stable PM peak was found at 15.6 s. We found a weak seasonal variation of microseism activity; relatively stronger SM occurred during the dry season. We identified directional incident Rayleigh waves at periods of 1–2 s and 2–4 s, with no seasonal variation in the source locations at most of the stations and distributed source directions at periods of 4–8 s. Conversely, seasonality in P-wave sources at periods of 4–8 s is strong for most of the Cuban stations: sources originating from the north and south, corresponding to the local winter of the northern and southern hemispheres, respectively. These findings contribute to a better understanding of microseisms at locations of weak ocean microseism sources.

Manual and automatic segmentation techniques can be applied to DICOM medical images from magnetic resonance imaging (MRI) to extract certain structures, such as soft tissues, but the precise extraction of bone structures may be limited. This study studies these types of knee bone tissue segmentation on MRI, to avoid the need to resort to computed tomography (CT) for obtaining the desired bone structures. Manual segmentation was done using ITK-Snap and automatic segmentation algorithms were applied in Python and the ITK library. As a result of this study, it was found that although manual segmentation allowed for precise and consistent identification of the femur, tibia, fibula, and patella, the automatic segmentation needed to achieve the same level of accuracy.
Parallelization of a Method to Infer Genetic Networks in Multi-CPU Systems
Authors: Darriba Javier , González Jorge
Published: February 2025

Genetic regulatory networks represent the interactions present between genes and are a crucial step in understanding cellular physiology and complex pathological phenotypes. There are various methods to infer these networks from a set of genetic data. Among them, the MRNET method stands out, which is based on the mRMR feature selection algorithm. However, constructing genetic regulatory networks with MRNET is a computationally expensive process for large-scale datasets due to its cubic complexity concerning the number of genes. The objective of this work is to develop parallel versions of MRNET that can be executed on shared-memory parallel systems to accelerate its execution.
Piotr Zaremba’s Travels to Nordic Countries after World War II
Authors: Siemianowski Jordan
Published: February 2025

Piotr Zaremba jest jednym z najbardziej zasłużonych mieszkańców Szczecina w powojennej historii tego miasta przede wszystkim dzięki zasługom na rzecz jego odbudowy. Jego dokonania doceniono w 2000 roku, gdy nadano mu miano szczecinianina stulecia. Autorytet, którym się cieszył jako urbanista i architekt specjalizujący się w budowlach portowych, sprawił, że stał się znany również poza granicami Polski. Ułatwiło mu to podróżowanie do wielu krajów, w tym nordyckich. Jako osoba ze wschodniej strony „żelaznej kurtyny” budził duże zainteresowanie.

Celem artykułu jest próba odpowiedzi na pytania dotyczące planów przyświecających P. Zarembie przy tych delegacjach, ich charakteru oraz znaczenia zarówno dla kraju odwiedzanego, jak również związanego z P. Zarembą środowiska szczecińskiego. Przeprowadzona analiza pozwala stwierdzić, że podróże szczecińskiego urbanisty do państw nordyckich miały charakter polityczny, kulturalny oraz gospodarczy. Przynosiły one wymierne rezultaty, np. w postaci utworzenia połączenia promowego Szczecin–Trelleborg, były m.in. częścią polskiej polityki zagranicznej, a także potwierdzały bardzo dobrą reputację P. Zaremby, jaką cieszył się za granicą.
"I attach great importance to this contact." The Relations between the Parisian "Kultura" and the Szczecin weekly "Ziemia i Morze" in the light of correspondence and publications of both periodicals
Authors: Krasucki Eryk
Published: February 2025

Tygodnik „Ziemia i Morze”, wydawany w Szczecinie w latach 1956–1957, pozostaje fenomenem w skali regionalnej. Był również częścią większego zjawiska, jakim była prasa „odwilżowa”, zjawiskiem, które nadawało ton zmianom kończącym w Polsce okres stalinowski. W 1956 roku pismo nawiązało kontakt z wydawanym w Paryżu miesięcznikiem „Kultura”, najbardziej wpływowym tytułem polskiej prasy emigracyjnej po II wojnie światowej. Skutkiem tego były publikacje w obu tytułach, a także wymiana korespondencji pomiędzy redaktorami naczelnymi obu pism. Tekst jest omówieniem i analizą relacji łączących w okresie „odwilży” obie redakcje – szczecińską i paryską. Stara się określić sposób wzajemnego postrzegania, kształt współpracy oraz wyjaśnić, czy kontakty miały charakter wyjątkowy w skali ogólnopolskiej. Bazę źródłową tekstu stanowią dokumenty archiwalne, publikacje prasowe oraz korespondencja pomiędzy dziennikarzami „Ziemi i Morza” a Jerzym Giedroyciem.

BRICS: proliferación nuclear y seguridad internacional
Authors: Rosas González María Cristina
Published: February 2025

El Tratado de No Proliferación de Armas Nucleares en el mundo se ha venido debilitando. Los países que originalmente integraron el grupo BRICS (Brasil, Rusia, India, República Popular China y Sudáfrica) son los mayores depositarios de armas nucleares. Dos de sus miembros, Brasil y Sudáfrica, desmantelaron sus respectivos programas nucleares en la década de los 80 del siglo pasado. Por su parte, entre India, la República Popular China y Rusia poseen 6487 ojivas nucleares, y es Rusia la que cuenta con el mayor arsenal. Si bien los cinco países son suscriptores del Tratado de la No Proliferación de Armas Nucleares (TNP), la “opción nuclear” se considera plausible ante los cambios geopolíticos ocurridos en el siglo xxi. La energía nuclear tiene usos duales. Los BRICS coinciden en la importancia de la desnuclearización, pero mientras que los tres países con armas nucleares se encuentran modernizando y ampliando sus arsenales, Brasil debate hasta dónde su programa puede ir más allá de la esfera civil, en tanto Sudáfrica apuesta por la energía nuclear para su desarrollo. El artículo plantea que la posesión de armas nucleares ha sido un deseo de los cinco países en distintos momentos y que la desnuclearización no es un objetivo de ninguno de ellos actualmente. Antes bien Rusia, que ha desmantelado a la par de Estados Unidos una gran cantidad de sus arsenales, no desea entablar un proceso similar ni con la República Popular China ni con India, dado que ello revelaría secretos en los procesos de verificación respectivos. Aunque Rusia es el país más nuclearizado y el líder del grupo en este tema, no se observa una política de consenso al respecto con el resto de los BRICS. Así, el propósito del presente artículo es analizar la evolución de la agenda nuclear en cada uno de los cinco integrantes originales del grupo BRICS y las dificultades para acuñar una agenda común de cara a la no proliferación nuclear en el mundo. La metodología es descriptiva para explicar la evolución de la postura nuclear de cada integrante del grupo, para, posteriormente, mediante la prospectiva, proponer escenarios posibles de cara a la proliferación nuclear global. La pregunta de investigación es si los BRICS están en condiciones de concertar una postura común en materia de no proliferación nuclear y por qué.
