Пространственно-временная трансформация геосистем впадин Байкальской рифтовой зоны
Authors: Ноговицына Мария Александровна
Published: October 2024

Цель исследования – выявить особенности пространственно-временной трансформации геосистем впадин Байкальской рифтовой зоны. Материалы и методы. Работа основана на данных полевых маршрутных наблюдений, анализе тематических карт, результатах экспертной интерпретации спутниковых снимков, обобщении литературных источников с использованием исторических, ландшафтно-ориентировочных и сравнительно-географических методов, ГИС. Результаты и обсуждение. Функционирование геосистем района исследований определяет ряд факторов: вещественно-энергетический обмен, развитие, внутренние и внешние взаимосвязи, резонанс, устойчивость. Эндогенные факторы оказывают пространственно-дифференцирующее воздействие практически на всех структурно-иерархических уровнях геосистем и являются сквозными природными агентами, контролирующими всю систему межкомпонентных взаимодействий. Преобразования под воздействием климатических и эндогенных факторов происходили синхронно и вызывали проявление резонансных явлений, которые стимулировали пространственно-временную трансформацию геосистем. С активными разломами рифтовых впадин связаны сейсмичность, вулканизм, тепловые потоки, гидротермальные процессы; разломы «контролируют» осадконакопление и положение речных долин. По зонам разломов восходящие потоки разогретого и разуплотненного мантийного вещества создают повсеместные тепловые потоки, которые непосредственно влияют как на компоненты геосистем, так и на пространственно-временную трансформацию геосистем в целом. Выводы. Изменение вещественно-энергетического обмена геосистемы с ее средой за счет эндогенной составляющей является одним из главных факторов формирования специфики трансформации геосистем впадин Байкальской рифтовой зоны. Наиболее интенсивной трансформации подвергнуты районы воздействия плюмов, флюидов мантии, развития магматических и метаморфических пород, крупных разломов. Сочетание разнообразных геодинамических режимов материкового рифтогенеза и горообразование вызвало неоднозначный отклик геосистем на изменение климата, что определило развитие в районе исследований на близко расположенных участках темнохвойной тайги, заболоченных лиственничных редколесий с кедровым стлаником и подтаежных светлохвойных геосистем.

Published: October 2024

Целью исследования является обсуждение трёх из многих приоритетных направлений в исследованиях конусов выноса как ландшафтных образований: методы, направленные на их диагностику и изучение; выявление потенциала задействованных тематических карт и их преобразование для получения новых знаний об объекте. Материалы и методы. Объект исследования – изучаемые автором с 70-х годов прошлого века ландшафты конусов выноса Казахстана, а также литературные и фондовые естественно-исторические материалы. Конусы выноса рассматриваются с позиций общенаучного системного и естественнонаучных подходов – пространственного, экологического и бассейнового. Результаты и обсуждение. Деление конусов выноса на конусы меньших размеров предстаёт как одна из основных закономерностей территориальной структуры этих природных образований. Ландшафтные единицы конусов выноса сходные морфологически, но занимающие неодинаковое положение в системе стока, не аналогичны, они отвечают критериям гомологичности. Рассматривается состав тематических карт, привлекаемых для изучения конусов выноса в аспекте ландшафтной географии; оценивается их явный и скрытый потенциал, возможности преобразования таких карт для получения новых знаний. Заключение. В научный оборот вводятся новые виды карт для диагностики и исследования морфологической структуры ландшафтов конусов выноса – карты линий тока бывших водно-грунтовых потоков, карты аналогов и гомологов конусных образований. Явным и наивысшим потенциалом обладают гидрогеологические карты. Становится для проработки тема о возможности преобразования тематических карт для получения новых знаний о конусах выноса как объектах ландшафтоведения.

Authors: Сивохип Жанна Тарасовна , Павлейчик Владимир Михайлович
Published: October 2024

Цель – выявить пространственно-временные особенности изменения параметров максимального стока в бассейне реки Урал. Материалы и методы. В качестве исходных данных для анализа многолетней динамики доли стока весеннего половодья приняты ряды гидрологических наблюдений по 12 гидропостам. Выбор гидропостов основан на различиях физико-географических условий стокоформирования и степени антропогенного воздействия на речной сток. Выводы о пространственных особенностях и тенденциях изменения максимального стока в исследуемом бассейне сформулированы на основе методов статистического анализа данных с учетом порогового года изменения водности (1978). Результаты и обсуждение. Многолетние изменения стока весеннего половодья рек бассейна реки Урал характеризуется определенными пространственными различиями. Минимальная доля в годовом объеме стока характерна для верховий реки Урал и его крупных притоков (рек Сакмара, Большой Кизил и др.). Наиболее значительным сокращением доли стока весеннего половодья характеризуются реки с зарегулированным режимом. Взаимосвязь между уменьшением доли весеннего половодья в годовом объеме стока и сокращением средних и абсолютных значений максимальных расходов установлена, прежде всего, для зарегулированных участков рек (Урал – Оренбург; Илек – Веселый) и отдельных водотоков с условно-естественным режимом (Урал – Верхнеуральск; Орь – Истемес; Салмыш – Буланово). Выводы. Установлено, что для рек исследуемого бассейна свойственны современные тенденции изменения максимального стока, наблюдаемые на Европейский территории России. Выявлена трансформация сезонного распределения стока в сторону увеличения доли меженных стоков (особенно зимнего) и сокращения доли стока весеннего половодья. В итоге, изменения внутригодового распределения речного стока обусловливают определенное выравнивание гидрографа годового стока рек с казахстанским типом водного режима.

Published: October 2024

The development of hydraulic structures has impacted the river discharge and sediment transportation, thus highlighting the river planform changes. Among 103 river catchments in Sri Lanka, the Mahaweli River is the longest river with the largest basin. Many development projects over the years diversely impacted the changes in river masks. However, no study has been conducted to quantify the planform changes in the lower Mahaweli River. Therefore, a comprehensive study was conducted to analyse the river planform changes over 30 years (1991-2021) from Damanewewa to Trincomalee. Freely available remotely sensed satellite data with 30 m resolution were used in the analysis. These images were processed using the QGIS mapping tool and RivMAP toolbox in MATLAB. Major changes were identified at the downstream part of the river and an oxbow lake formation was also observed. The average width for the entire reach (Wra) was identified as 14.83 m and channel width average (Wavg) was noted as 18.09 m. In addition, erosion and accretion rates were calculated, and the cumulative sequence of these rates was increased over the years affecting the change in channel width. Furthermore, the migration rates were also computed with generated river centerline. Highest migration rate reached about 400 m/yr, in the downstream which finally leads to severe meandering. Results revealed that this methodology can be applied to similar river planform analysis. Further, these results showcase the potential importance of analyzing channel stability as well as for water resource management.

This study compares the performance of various machine learning models for predicting landslide susceptibility using a geospatial dataset from the Lai Chau province, Vietnam. The dataset consisted of 850 landslide locations and ten influencing factors. Eight models, including Forest by Penalizing Attributes (FPA), Bagging-based FPA (BFPA), Artificial Neural Network (ANN), Logistic Regression (LR), Support Vector Machine (SVM), Multilayer Perceptron (MLP), Bayesian Network (BN), and Naïve Bayes (NB), were evaluated based on different evaluation metrics. The results revealed distinct variations in the performance of the models across the evaluation metrics. Based on the overall rankings, the ensemble BFPA model with sensitivity=90%, specificity= 95.98%, accuracy=92.86%, Kappa=0.857, and area under the curve=0.98 demonstrated the highest capability in predicting landslide susceptibility. It was followed by BN, FPA, MLP, ANN, SVM, LR, and NB. These findings suggest that the BFPA model outperformed other models in terms of its ability to accurately identify potential landslide-prone areas in the study region. This study provides valuable insights into the comparative analysis of machine learning models for landslide susceptibility prediction. Furthermore, it supports the effectiveness of ensemble models for landslide susceptibility prediction, which can inform decision-makers, land-use planners, and disaster management agencies in making informed decisions regarding potential landslide hazards and implementing effective risk mitigation strategies in Vietnam. Continued research in this area will enhance our understanding of machine learning techniques and their application in mitigating the impact of landslides on society and the environment.

Authors: Gomes Antonio , Cunha Jacqueline , Bispo Jorge , Lourenço Isabel
Published: October 2024

Objetivo: Verificar se, no âmbito da tributação federal, a complexidade tributária e os parcelamentos especiais repetitivos estão associados ao aumento da probabilidade de desobediência tributária das empresas listadas na B3. Método: Foi desenvolvido um modelo logit em painel estimando a probabilidade de uma empresa ser desobediente a partir das variáveis independentes complexidade tributária, parcelamentos especiais, probabilidade de fiscalização, custos de fiscalização, taxa Selic e utilidade esperada, controladas pela liquidez corrente, EBITDA e tamanho da empresa. Resultados: A pesquisa identificou que a complexidade tributária e os parcelamentos especiais repetitivos aumentam a probabilidade da desobediência tributária das empresas listadas na B3. Os resultados também evidenciaram que a baixa probabilidade de fiscalização, assim como os altos custos de fiscalização, a necessidade de caixa e a utilidade esperada afetam positivamente a probabilidade da desobediência tributária nas empresas analisadas. A partir desses resultados, entende-se que o Brasil deve reduzir a sua complexidade tributária desnecessária. Contribuições: Compreender os determinantes e as consequências da desobediência tributária no Brasil é significativo para melhor gestão dos recursos escassos da fiscalização, bem como norteia políticas públicas eficientes para geração de emprego e renda para a população. Assim, a pesquisa contribui com toda a sociedade ao evidenciar a necessidade de uma reforma tributária que reduza a complexidade tributária desnecessária e facilite a compreensão das leis tributárias.

Published: October 2024

Objetivo: O trabalho analisou a influência da reputação corporativa (RC) como fator moderador da responsabilidade social corporativa (RSC) na agressividade fiscal das empresas da B3. Método: A amostra totalizou 106 empresas de capital aberto listadas na bolsa de valores brasileira, no período de 2010 a 2021, gerando assim 1.272 observações. Foi utilizado o modelo de dados em painel para análise dos dados. A proxy para RC foi a classificação do Anuário da Revista Exame. Para RSC, foi coletada a pontuação ESG da Refinitiv Eikon®. A ETR Diferencial Normalizada foi utilizada como proxy para agressividade fiscal. Resultados: Os resultados mostraram relação negativa entre agressividade fiscal e RC, quanto à agressividade e RSC, não houve significância estatística. Contudo, a relação se inverte quando a RC modera a RSC, o que pode ser explicado pela Teoria do Licenciamento Moral, em que empresas com créditos morais (representadas pela RC e níveis altos de RSC conjuntamente) utilizariam de sua licença moral para serem mais agressivas. Contribuições: O trabalho propõe uma medida de agressividade fiscal que visa maior precisão e confiabilidade, a ETR Diferencial Normalizada. Assim como agrega com mais uma análise acerca do tema, avaliando o fator moderador da RC e RSC sobre a agressividade.

The Mediating Role of Brand Love between Brand Personality and Brand Loyalty: A Study on SMEs Traditional Woven Fabric in Indonesia
Authors: Hardilawati Wan Laura , Ghani Noor Hasmini Abd
Published: October 2024

This paper aimed to examine the impact of brand personality dimensions (sincerity, excitement, and competence) on brand loyalty. In addition, the role of brand love is explored through mediation models. A total of 384 valid and usable responses collected from a consumer of Traditional SME Traditional Woven fabric in Indonesia were analyzed through the structural equation model (SEM). A research model examined several hypotheses underpinned by multidimensional brand loyalty and interpersonal love. The findings showed that sincerity and competence had a significant impact on brand loyalty and brand love, but excitement had no significant impact on brand loyalty and brand love. Moreover, brand love mediated the relationship between sincerity and competence, but excitement had an insignificant impact. The results of this study indicate that small and medium-sized enterprises (SMEs) in the traditional woven fabric industry should foster emotions to establish a robust consumer-brand connection. Furthermore, it is critical to prioritize the development of robust attributes, as traditional woven textiles possess deeply ingrained cultural significance. This study contributes to the current knowledge of brand loyalty literature by exploring the characteristics of brand personality and brand love. The findings imply that when consumers' brand personality is mixed with brand love, it will result in increased loyalty towards the brand.
The image of the hero of Ukrainian fairy tales in the context of differentiation and transformation of the hierarchy of socio-cultural practices
Authors:   Taras Shevchenko National University of Kyiv, Kyiv, Ukraine, Pavlova Olena , Rohozha Mariya ,   Taras Shevchenko National University of Kyiv, Kyiv, Ukraine
Published: October 2024

Background. The Modern era, with its paradoxes of innovation and repetition, shaped the "discovery of the people" and rekindled interest in folktales. Enlightenment models of fairy tales emphasized the ethical dimension, while the romantic moods of the 19th century stirred European communities' interest in gathering national and regional versions of folktales and converting them into literary fairy tales. The perspective of contemporary humanities proves to be quite productive to enhance the understanding of the cultural potential of Ukrainian fairy tales in bridging diverse traditions and generating images. Methods. The methodological basis for the study is a content analysis of a collection of fairy tales. A categorization is based on the titles of folktales and the classifications of J. Campbell's transformations of the hero. The interpretation of the data is made in optics of the differentiation of a segmentary society and the specifics of its transformations of representation practices, first of all the image and the image of a hero. The aim of the article is to define fundamental characteristics of the image of a hero in Ukrainian fairy tales as a way of representation in logics of the differentiation of a segmentary community. Results. The differentiation of practices begins with the complexification of a segmentary society, where storytelling practices were detached from the original ritual syncretism in the logic of ethnic diversity production and strata hierarchy. Each stratum nurtured its storytelling genre and thematic uniqueness. With its functioning in the magical and practical unity of the peasant stratum, the folktale preserved the most archaic narrative structure, with corresponding images of the main characters and logic of image construction. The image of the folktale hero became the leading practice in representing communities. Conclusions. A content analysis of a collection of Galician folktales reveals the replication of the classic triad of popular culture "Heroes, Villains and Fools" (P. Burke), marked by a dominant quantitative representation of the fool's image. A fairy tale hero is a dormant hero, leaving the impression that everybody can find their place. The hero's heroic powers are exposed gradually, and the hero possesses definite traits and personifies moral integrity. These qualities allow the overcoming of obstacles and passing of tests. Usually, the hero of a Ukrainian fairy tale is a trickster who can maneuver through society. The ethical pathos of a fairy tale consists of a victorious war between evil and justice/resumption. The predominantly happy ending of Ukrainian fairy tales suggests these functions provide a therapeutic effect in difficult historical circumstances.
J.R.R. Tolkien's non-classical myth practices: mytho-logical analysis
Authors:   Ukrainian National Tchaikovsky Academy of Music, Oleksin Danylo
Published: October 2024

Background. The relevance of our research is indicated by the high level of involvement of John Ronald Reuel Tolkien's creative compendium in shaping and constructing modern culture. Over the past twenty-three years of the 21st century, a significant number of projects have articulated and realized their own interpretations of J. Tolkien's mythology. It is enough to mention Peter Jackson's film trilogies, "The Lord of the Rings" (2001-2003) and "The Hobbit" (2012-2014), a series of video games in various genres by Chris Cornell, William Gordon, and Jill Eckhart, such as "The Lord of The Rings: The Battle for Middle-earth" (2004, 2006), Eric Gewirtz's "The Lord of the Rings: Conquest" (2009), John Fleming, Lucas Riting, and Ruf Tomandi's "The Lord of the Rings: War in the North" (2011), among others. Method. Our research's method is based on the mytho-logic method, which involves interpreting myth in the context of its logic and structure (in the interpretation of "The Lord of the Rings" and "The Silmarillion"). Results. An interpretation of "The Lord of the Rings" and "The Silmarillion" in harmony with the logic of myth through its axioms and laws has been carried out, demonstrating the mythic nature of these texts through their full compliance with the axioms and laws of myth logic. The interpretation of "The Lord of the Rings" through structural analysis of selected narrative variants has been articulated. Twelve main mythemes have been identified and their significance for the mythic narrative has been argued. The images of Gollum, Sméagol, Faramir, and Frodo have been interpreted through a mythic matrix, where the first represents the unconscious Shadow of any subject, the second is a subject attempting to contend with it, the third is a subject that conquers it, and the fourth is a sum of the Hero's image, one who has no "simple life" in a "simple world." Conclusions. We consider our mytho-logic to be a valid method for interpreting myths of any spatial and temporal category. It is worth noting that mytho-logic, like any non-classical humanities method, is not purely ideal and does not have all the answers. Any interpretation is an interpretation, neither worse nor better, but the question here lies in the substantiation of conclusions. We deem our research to be substantiated, although unfinished, as new mythemes of "The Lord of the Rings" can and should be explored, new combinations of these mythemes interpreted differently, and explanations offered. This demonstrates the inexhaustibility of meanings in myth, non-classical approaches, and mytho-logic as a method.
Vernacular garden as urban landscape element (сomparative analysis of Kyiv and Prešov cases)
Authors:   Taras Shevchenko National University of Kyiv, Kyiv, Ukraine, Butsykina Yevheniia
Published: October 2024

Background. The aim of the paper is to compare the vernacular gardening within urban landscapes in Ukraine and Slovakia through its ability to enhance resident engagement and reduce levels of indifference and alienation. Methods. I apply Lehtinen's idea of urban aesthetics as a compromise, highlighting the significance of engaging with city imperfections to achieve urban harmony, as well as Jackson and von Bonsdorff offer contrasting perspectives on the landscape concept and urban environment, respectively. Cureton introduces the concept of "vernacular landscape," while Macauley emphasizes the embodied experience of walking in the city. Fenner's insights on gardens enrich the discussion by highlighting their historical resonance and aesthetic allure. Additionally, the text explores the interdisciplinary approach to analyzing vernacular gardens, drawing on concepts from Foucault and Heidegger to provide a comprehensive understanding of their socio-cultural and aesthetic significance within urban landscapes. Results. Vernacular gardens in Kyiv's Rusanivka microdistrict play significant role in intertwining private and public spaces through the lens of care. Amidst the backdrop of war in Ukraine, these gardens symbolize resilience and resistance. Contrasting vernacular gardening practices in Kyiv and Prešov , it highlights their distinct characteristics reflective of their urban landscapes, with Kyiv gardens representing individual initiatives against Soviet traditions and Prešov gardens seamlessly integrating into the urban fabric with a focus on post-Socialist architecture and individual creativity. Conclusions. The study of vernacular elements of the urban landscape, in particular – the vernacular garden and the practice of vernacular gardening, implemented through a combination of different approaches and disciplines: urban, negative and phenomenological aesthetics, cultural anthropology and cultural studies around the landscape, vernacular landscape and cityscape, as well as practical interview methods and walking the combination of different approaches made it possible to define a vernacular garden precisely as a place created by a creative subject within the urban landscape. It acquires the status of a heterotopia and a place that allows you to get involved in the urban environment, identify with it and feel its atmosphere.
Configurations of the personal, public, and professional in Facebook users' profiles: content analysis
Authors:   National University of ", Hrudka Orysia ,   Kyiv-Mohyla Academy",   , Kyiv, Ukraine
Published: October 2024

Background. Social media have become powerful platforms for self-representation and self-presentation. Researchers note that social networks blur the conventional boundaries between personal and public issues and spheres of life. Empirical analysis of personal profiles will help understand what issues (personal, public, or professional) and in what configurations users post on their social networks. The study aims to analyze the posts' meta-themes, types, and general patterns of configurations in 15 personal profiles of the Ukrainian Facebook space. Methods. Content analysis of 50 consecutive posts from 15 profiles of users of different ages, professions, and publicity was applied. Posts have been categorized by meta-themes (personal, professional, public) and types defined in the process of analysis (including dissemination of information about one's project, posts for memorable dates, diary accounting, diary reflection, meme, quote, opinion writing, etc). Results. Differences between the strategies of personal profile usage by public and non-public individuals were found. In particular, non-public users more often focus on personal topics, while public ones focus on professional ones. Popular types of posts were identified, such as diary accounting, diary reflecting, mapping of one's network, and project announcements. It was found that promoting one's own projects, journalism, and essay writing, as well as crowdfunding campaigns, are more common among public figures, while diary reflection, sharing photos, and memes are more prevalent among non-public users. Personal profiles in social networks perform a number of functions, such as being counterparts of live communication and self-presentation, spaces for opinion leadership, and involvement in collective events. Despite the proven diversity of profile management, each user demonstrates integrity and consistency in their approach. Conclusions. Unlike institutions and spaces of modernity, contemporary social networks combine different spheres of life (personal, professional, and public) in one space – in a single personal profile and even a single post. This creates both new opportunities for self-(re)presentation and challenges. Further empirical research involving qualitative methods is relevant for a deeper understanding motivation of users and their perception of the profiles.

Published: October 2024

This study analyzes the impact of the COVID-19 pandemic and the economic reactivation carried out in Ecuador in 2021 on the corporate performance of Ecuadorian companies; in this country, most of the business fabric is made up of micro and small companies, which is why it could provide new insights to the literature. The empirical analysis is based on the DID impact evaluation methodology from a company database obtained from the financial statements of the Superintendency of Companies of Ecuador. The results reveal that there is great heterogeneity in the corporate impact of the pandemic and that the affected ones were mainly micro and small companies; additionally, they indicate that the negative effects of the pandemic on financial performance extended into 2021, thus signaling a weak economic recovery. These results are key for designing policies aimed at economic reactivation in the business segments and industries most impacted by the pandemic.

This research aimed to analyze the moderating effects of ownership structure on the relationship between environmental, social, and governance (ESG) disclosure and information asymmetry in Brazilian companies. A quantitative, descriptive, and documentary study was conducted with data from 68 companies listed on the Bolsa Brasil Balcão (B3) between 2015 and 2022, tested using the one-step GMM dynamic panel system. The main findings indicate that ESG disclosure can reduce information asymmetry, while ownership concentration and institutional ownership have a positive moderating effect on this relationship. The study emphasizes the need for regulatory actions to address potential issues faced by less informed investors and improve the disclosure of ESG practices.
El Centenario de la Batalla de Boyacá en Bogotá. Mujeres, ritos y espacio urbano
Authors: Prieto-Páez Leopoldo
Published: October 2024

This article examines the commemoration of the Battle of Boyacá in August 1919 in Bogotá. While there have been few studies of this event in Colombian historiography, recent works in urban history have primarily focused on the transformation of physical space, neglecting other important aspects. In this study, we take a different approach, examining the role played by a group of women in shaping the type of celebration held and the creation of a specific city model based on their experiences. To do this, we employed a spatial analysis of the commemoration and a search and interpretation of historical documents that were subjected to new questions. Ultimately, our findings demonstrate the importance of considering the interrelation between urban history and women’s history in understanding previously underestimated urban processes.

Island archipelagos are well known for promoting geographic and adaptive radiations in terrestrial animals. Sympatry of closely related species in island systems has been thought to occur primarily through double-invasions from the same continental source population. Alternatively, this process can occur on a smaller geographic scale where divergent populations isolated from one another within an archipelago may come back into contact via intra-archipelago dispersal. Depending on degree of divergence and the development of reproductive isolating barriers, the result of this secondary contact could be gene flow between isolated populations, exclusion or extirpation of one population via competition, or the establishment of reproductively isolated sympatric species. Here, we provide strong evidence for intra-archipelago secondary sympatry within a radiation of Phylloscopus warblers in the Solomon and Bismarck archipelagos by presenting the first well-sampled phylogeny of Phylloscopus warbler populations in the region. By using genome-wide genetic data and complete mitochondrial genomes we also present evidence for a complex history of mitochondrial-nuclear discordance within this radiation, particularly in the only pair of sympatric populations east of Wallace’s Line, located on Kolombangara Island in the Solomon Islands. Our genomic data suggest that the divergent single-island endemic species on Kolombangara (Phylloscopus amoenus) is not a relic resulting from a double invasion from outside the Bismarck and Solomon archipelagos as previously thought. Rather, the sympatry on Kolombangara Island between the widespread P. poliocephalus and the endemic P. amoenus appears to result from recent intra-archipelago diversification, either via sympatric speciation or the rapid establishment of secondary sympatry. These novel genomic data provide insights into the evolutionary history of Phylloscopus warblers in Melanesia and improve our general understanding of how biodiversity accumulates in island systems.

Háttér és cél – A stroke súlyos egészségügyi probléma, ami jelentős hatással van az egészséggel összefüggő életminőségre. Annak ellenére, hogy egyre népszerűbb az életminőség mérése a betegek körében, nem mérik rendszeresen a klinikai gyakorlatban, ebből kifolyólag kevéssé ismert, hogy a klinikai mérések mennyire tükrözik a stroke utáni életminőséget. Kutatásunk célja az akut ischaemiás stroke-on átesett betegek életminőségének vizsgálata volt. Módszerek – A prospektív vizsgálatba a Pécsi Tudományegyetem Klinikai Központ Neurológiai Klinika akut ischaemiás stroke diagnózissal felvett betegeit kényelmi mintavétellel választottuk ki 2022 júniusa és 2023 májusa között. A betegeket a kapott kezelések alapján intravénás thrombolysis- (IVT-), mechanikus thrombectomia- (MT-) és standard ellátás- (SC-) csoportokba soroltuk. A kutatásban módosított Rankinskálát (Pre-mRS, follow-up mRS), NIH Stroke Scale-t (NIHSS) és European Quality of Life 5 Dimensions Scale-t (EQ-5D-5L) használtunk. Az elemzéshez leíró statisztikát, párosított T-próbát, Wilcoxon-próbát, McNemar-tesztet és Pearson-korrelációt alkalmaztunk (SPSS 25.0; p < 0,05). Eredmények – A kutatásban 198 fő (115 férfi, 83 nő) vett részt (MT: 50 fő, IVT: 69 fő, SC: 79 fő). A Pre-mRS, illetve a follow-up mRS-értékeknél látható, hogy mindhárom csoport esetében a 0–2 közötti, enyhe kategóriába került a legtöbb beteg (PremRS: 176 fő; 88%, follow-up mRS: 158 fő; 80%). A NIHSS-értékek alakulása kapcsán mindhárom csoportban szignifikáns javulást tapasztaltunk (IVT: 4,36 vs. 1,57, p<0,001; MT: 8,98 vs. 4,50, p<0,001; SC: 4,38 vs. 2,84, p < 0,001). Az EQ-5D-5L-érték szintén minden csoport esetében szignifikánsan nőtt (IVT: 0,82 vs. 0,88, p<0,001; MT: 0,63 vs. 0,73, p<0,001, SC: 0,76 vs. 0,80, p=0,014). Az alacsonyabb NIHSS-értékkel felvett betegek jobb életminőségről számoltak be vizsgálatunk végére (r: –0,43451). Következtetés – A 30. napnál az EQ-5D-5L életminőség tekintetében az MT-, IVT- és SC-csoportokban szignifikáns javulást tapasztaltunk, ám a javulás mértéke az MT-csoportban volt a legmagasabb.

Background and purpose – This prospective study aimed to investigate differences in video head impulse test (vHIT) and cervical vestibular evoked myogenic potential (cVEMP) findings between patients with vertebrobasilar insufficiency (VBI) and Meniere’s disease (MD) who experience episodic vertigo attacks. Methods – A total of 27 patients with VBI and 37 patients with MD were enrolled into the study in a tertiary referral center. Inclusion criteria consisted of patients with a minimum of two previous vertigo attacks, unaccompanied by any neurological symptoms during an attack. All patients underwent horizontal canal h-vHIT and c-VEMP assessments following pure sound audiometric examinations. First, vHIT and cVEMP results for low and high flow sides in VBI patients were analyzed. Subsequently, data from the low-flow side in VBI patients and the affected side in MD patients were compared. Results – The mean vHIT values for low and high-flow volume sides in VBI patients were 0.68 and 0.88, respectively. In MD patients, mean vHIT values for affected and healthy sides were measured as 0.77 and 0.87, respectively. Abnormal results were observed in 66.7% of VBI patients and 51.4% of MD patients, with no statistically significant difference between the findings (p> 0.05). Upon examining the affected side, c-VEMP responses were absent in 41% of MD patients and 48% of VBI patients, with no statistically significant difference between the groups (p> 0.05). Conclusion – vHIT and cVEMP assessments can be utilized as supplementary tools to radiologic investigations for the clinical diagnosis and follow-up of VBI. However, no significant differences were observed between vHIT and cVEMP findings in patients with MD and VBI.
