Introduction: Although hypertension is common, it can be dangerous if not treated promptly. Many people with the condition don't experience any symptoms. However, some may develop symptoms such as headaches, blurred vision, and chest pain. Regular check-ups are the best way to monitor blood pressure levels. According to the WHO, almost 46 % of adults are unaware that they have hypertension; nearly 63% of all deaths in India are caused by non-communicable diseases, with 27% attributed to CVD, which affects 45 % of individuals aged 40 to 69. Method: A cross-sectional study was conducted over a 2-months period in May and June 2024. A convenience sampling technique was used to select a total of 545 participants. The data were collected and then entered for analysis. Bivariable regression analyses were performed. AOR with a 95% CI was used as a measure of association. Variables having a p-value < 0.05 were considered to have a significant association with the outcome. Result: The prevalence of hypertension among adult in this study was 71.7%. Age 40 – 59 [AOR: 0.409, 95% CI: 0.275, 0.610], Muslim [AOR = 1.628, 95% CI = 1.450, 1.830, p = 0.000], college/University [AOR: 0.185, 95% 0.109, 0.314, p=0], Daily labourer [AOR: 1.941, 95% CI: 0.921,4.093, p=0.040], Family history of hypertension [AOR: 0.509, 95% CI: 0.371,0.699, p=0.000], overweight [AOR = 0.448, 95% CI = 0.290, 0.695, p = 0.000 ], Tobacco used [AOR = 0.588, 95% CI = 0.415, 2.853, p = 0.000], Alcohol consumption [AOR = 0.295, 95% CI = 0.68, 0.520, p = 0.000] and used smoking [AOR = 0.333, 95% CI = 0.213, 0.523, p = 0.000] had a statistically significant association with having hypertension. Conclusion: There is a relatively high prevalence of hypertension among adults. Associated risk factors such as overweight, regular checking of blood pressure, tobacco use, alcohol consumption, physical activity, and current smoking status have a significant positive association with hypertension. It is important to provide proper training programs and essential services to healthcare professionals. Community-based hypertension screening programs should be developed to prevent this silent and deadly disease.

Abstract  Community Service Activities startedfrom the results of a survey of environmental conditions in Bumi Makmur District which is a fostered village of the Islamic University of Kalimantan Muhammad Arsyad Al Banjar. From the results of the survey it was recorded that the life of the local community was quite communal.Traditional wisdom is one of the cultural heritages that exists in society (traditional) and is carried out from generation to generation by the Bumi Makmur community.In society, it is not uncommon for radicalism to develop. The rise of radicalism in society can have implications for stability and security between religious communities. Radicalism and terrorism both use open violence as instruments to achieve their interests. Radicalism can be carried out through brainwashing mechanisms and rejection of the law and Pancasila. The service method is carried out in stages, namely the preparation stage and the implementation stage. Village officials are an important component in society, because they are in direct contact with the community, village officials have various benefits, one of which is in terms of prevention. This service activity aims to provide counseling and training to educate and improve the skills of the Bumi Makmur village head in preventing the development of radicalism.

Exploring Vocabulary Learning Strategies of First Year Non-English Majors at University in Vietnam
Authors:   Thu Dau Mot University, Vietnam, Phuoc Binh Nguyen Thi
Published: January 2025

Many non-English major students often find it difficult to learn new words, especially first-year students. However, they are required to learn a large amount of vocabulary each day to understand their higher education lessons. Additionally, even if they manage to remember new words, they often struggle to use them effectively in communication. This paper addresses the question: What difficulties do first-year non-English major students at Thu Dau Mot University encounter in learning vocabulary? The hypothesis is that these challenges primarily stem from a lack of effective language learning strategies. To explore this, we conducted ten individual interviews with students to support a discussion regarding the hypothesis. This paper includes a discussion and analysis of the survey results, designed to gather insights into vocabulary learning strategies among first-year non-English majors at Thu Dau Mot University in Binh Duong. The study's final results confirm the hypothesis. At the conclusion, we propose solutions to help students overcome these challenges, improve their vocabulary acquisition, and benefit from more effective learning strategies.

European context of the architecture of the "Nafta-gas" building in Novi Sad
Authors: Gubić Ilija , Villa Riccardo
Published: January 2025

The architectural and urban significance of the "Nafta-gas" building in Novi Sad is analyzed within the broader European context. Situated along Liberation Boulevard, a prominent urban axis, the building symbolizes postmodernist tendencies in late 20th-century Serbian architecture. Designed through a public competition in 1985, the building reflects the era's socio-political aspirations, blending monumental and modernist elements. Influenced by postmodern architectural principles, the structure juxtaposes mass and transparency, employing advanced construction techniques and high-quality materials. The paper traces its evolution from conceptual design to partial realization, emphasizing its role as both a symbol of transformation and a focal point within Novi Sad's urban landscape. The challenges of preserving postmodernist heritage amidst evolving urban contexts are critically addressed, underscoring the need for systematic protection of such landmarks. The study highlights the building's dual nature: as an innovative design of its time and as a reflection of complex socio-economic conditions in Serbia during the 1990s.

Published: January 2025

Abstract
Background: Occupational noise-induced hearing loss poses a significant health risk especially for military and low enforcement. Unlike steady, prolonged noise, impulse noise, such as gunfire, lead to more immediate and severe hearing impairment. This study explores the link between sensorineural hearing loss and cytokine levels in nasal secretions of male and female military cadets exposed to high-intensity gunfire noise.
Methods: 105 cadets (75 males and 30 females, aged 19–25) undergoing regular firearms training were included. Audiometric testing and measurement of IL-1β, TNF-α, GM-CSF, and IL-10 concentrations in nasal secretions were conducted at three-time points: 24 hours before, immediately after and 24 hours following noise exposure.
Results: Acute acoustic trauma affected the hearing of 39% of male and 21% of female participants. Among those with audiometric changes, IL-1β levels increased immediately after exposure, while both IL-1β and GM-CSF levels were elevated 24 hours later. Nasal IL-1β and GM-CSF levels significantly changed across all participants, with the most pronounced alterations seen in those with audiogram changes. Male cadets exhibited higher values of pro-inflammatory/anti-inflammatory cytokine ratios compared to female cadets.
Conclusions: Acoustic trauma associated with a certain degree of hearing loss due to noise exposure is linked to an increase in nasal pro-inflammatory cytokine levels, and this effect is more pronounced in men than in women.

European beech (Fagus sylvatica L.) forests are one of the largest natural renewable reservoirs of stored carbon in Europe, as well as in the Balkans and Serbia. A number of factors have been identified which influence the state of stored carbon, but a unique influence can be expected from the degree of stand preservation and the history of forest management. In the present paper, the influence of the preservation of stands and management methods on the state of ecosystem carbon (biomass carbon and soil carbon) were analyzed in beech forests situated at the Fruška Gora Mountain, Serbia. The research was conducted in three stands that were managed in the past in three different ways: a virgin forest without any management, a high stand and a coppice stand. The stored biomass carbon and soil carbon was estimated using standard methods that have been previously proven useful in Europe for the last decades. Above-ground biomass was also assessed using remote sensing. The results show a significant impact of conservation and management history on the stock of stored biomass carbon and soil carbon, but also on their mutual relationship. This research initiates that moderate management measures and the application of management systems based on the principles of continuous cover forestry (selective and group cutting) are, in addition to their well-known advantages, more efficient in carbon storage than the application of systems with surface management (clear and shelterwood cutting).

Estudo numérico da perda de carga de uma válvula do tipo globo
Authors: Angelo Edvaldo , Temístocles Luciano , Campanella Fabrício Leonardi , Benítez Barrios Daniel
Published: January 2025

O coeficiente de perda de carga é um parâmetro adimensional indicativo do processo inevitável e irreversível de transformação de parte da energia de um fluido em escoamento em parcelas não úteis. A minimização do referido adimensional é certamente desejável especialmente no que tange a necessidade de despender a menor quantidade de energia possível em processos como o de bombeamento. Para dispositivos como válvulas há possibilidade da escolha de geometrias internas que objetivam diminuir tanto a quantidade quanto a intensidade de vórtices e regiões de separação no escoamento. Essas regiões são as principais causadoras do aumento do coeficiente de perda de carga. Através do software comercial Ansys CFX® foram modeladas e simuladas diversas geometrias internas de válvulas globo. O estudo foi realizado em duas etapas, sendo que na primeira foi estudado o escoamento no interior da válvula, mantidas as características construtivas tipicamente encontradas no mercado. Na segunda etapa foi analisado um modelo de válvula com geometria interna modificada. Na melhor condição, para geometria proposta o coeficiente de perda de carga, sofreu decréscimo de até 54,18% (em situação particular). Os resultados ainda indicaram que no processo de abertura da válvula, a partir de uma determinada posição da haste, não se verificou mais influência deste parâmetro nas condições do escoamento, tão pouco nos casos em que, sob as mesmas condições foi variada a forma geométrica da haste.
Aplicação de um método de interacção fraca víscidoinvíscido no projecto da roda de uma turbina axial
Authors: Cabral Ferro Luís Morão , Eça Luís , Gato Luis Manuel de Carvalho
Published: January 2025

É apresentada uma metodologia de projecto que combina o método da curvatura de linhas de corrente com o método de painel com interacção viscosa. O método de curvaturas de linhas de corrente é usado na determinação do escoamento meridiano que se assume axissimétrico. O escoamento entre pás, que se considera desenvolver em superfícies de corrente cilíndricas coaxiais com o eixo da turbina, é resolvido pelo método de painel para uma cascata de perfis com interacção fraca víscido-invíscido. No método de painel utilizado, os perfis da pá são discretizados em elementos rectilíneos com distribuições de fontes de intensidade constante. A circulação em torno dos perfis é simulada utilizando uma distribuição de vórtices ao longo da linha média do perfil, cuja intensidade é dada por 0,4 0 m γ = γ s , onde sm é a distância medida a partir do bordo de fuga ao longo da linha média do perfil e γ0 é uma constante determinada pela aplicação da condição de Kutta. A camada limite ao longo da superfície do perfil é calculada utilizando o método integral de Thwaites na zona laminar e o método de Head na zona turbulenta; a transição da camada limite é condensada num único ponto. O efeito da camada limite no escoamento potencial é simulado pela introdução de uma velocidade de transpiração na superfície do perfil. Os perfis escolhidos para a pá são do tipo NACA série 6 modificada. Uma distribuição linear de espessura máxima dos perfis ao longo do raio é especificada. A flecha dos perfis e o ângulo de calagem são ajustados de modo a induzirem a deflexão pretendida e a obter uma distribuição suave de pressão ao longo do contorno do perfil. A metodologia é aplicada com sucesso no projecto de uma pequena turbina tubular do tipo axial. Os resultados obtidos são comparados com os obtidos por um um método de projecto análogo em escoamento invíscido. A aplicação do método é simples, pouco dispensiosa em tempo de CPU e permite, quando comparado com o projecto invíscido, detectar a possibilidade de ocorrência de separação de camada limite.

LA INSATISFACCIÓN EN EL RELATO BREVE ERÓTICO ESPAÑOL ACTUAL. CONSIDERACIONES SEMIÓTICAS
Authors: Muro Munilla Miguel Ángel
Published: January 2025

Este artículo ofrece una reflexión semiótica sobre los relatos breves eróticos en la literatura española actual y pone de manifiesto cómo la insatisfacción es uno de sus rasgos distintivos y se convierte en un síntoma de malestar existencial que imposibilita la comunicación. Las razones que explican esta condición son tanto literarias —referentes como Nin, Lawrence, Miller o Bukowski, que problematizan el erotismo—, como extraliterarias —vivencia existencial de la experiencia erótica—. Esta insatisfacción, no obstante, no desactiva la función excitante de estos relatos, bien por la autonomía funcional de los pasajes más propiamente incitantes del deseo, bien porque lo negativo se asume en la experiencia erótica.

To this end, the main theoretical contributions on the author’s image are first reviewed to establish which concepts and terms are most operative for this study. Following this state of the art, Sabina’s authorial image is approached from a diachronic perspective and an authorial project is identified, dominated primarily by an image of a rebellious scoundrel and mainly integrated by the authorial posture of the prototypical singer-songwriter, the nocturnal debauchee fond of vices, the poet, and the old man.
Keywords: Author’s image. Authorial project. Authorial posture. Ethos. Joaquín Sabina. Spanish singer-songwriting.
EL NARRADOR EN LA AUTOFICCIÓN DRAMÁTICA. LOS GONDRA (TRILOGÍA), DE BORJA ORTIZ DE GONDRA
Authors: CORRALES DÍAZ-PAVÓN José
Published: January 2025

La teoría sobre la autoficción dramática parte de la ausencia de la figura del narrador como clave para explicar las presuntas diferencias entre la autoficción narrativa y la que se escribe para el teatro. Sin embargo, la semiología del teatro y estudios de referencia como el de Abuín demuestran, a nivel teórico, lo que la escritura dramática del siglo XX evidencia: que la figura de un narrador teatral es perfectamente posible. Así, en este estudio se utilizará este concepto y el de didascalia propuesto por García Barrientos para analizar los mecanismos autoficcionales en la trilogía Los Gondra, de Borja Ortiz de Gondra, una de las más reconocidas dentro del panorama dramático español.
Palabras clave: Autoficción dramática. Narrador. Didascalia. Identidad. Borja Ortiz de Gondra. Los Gonfra.
Abstract: The theory of dramatic autofiction is based on the absence of a narrator figure to explain the differences between narrative autofiction and theatre. However, Anxo Abuín’s classic study and theatre semiology show that a theatrical narrator is possible, as is the case in 20th Century dramatic writing. This study will analyse the narrator and stage directions as autofictional mechanisms in Borja Ortiz de Gondra’s Los Gondra (trilogía), which is widely recognised as one of the most important dramatic autofictions in the Spanish dramatic panorama.
Keywords: Dramatic autofiction. Narrator. Stage direction. Identity. Borja Ortiz de Gondra. Los Gondra.
ANÁLISIS DE LA CREACIÓN ACTORAL DESDE LA PERSPECTIVA SEMIÓTICA. UN ESTADO DE LA CUESTIÓN
Authors: FONS SASTRE Martín B.
Published: January 2025

El presente artículo se centra en el estudio de la actuación, del proceso de creación actoral, desde la perspectiva semiótica. Se pretende discutir y analizar las aportaciones que ha desarrollado esta perspectiva científica para la compresión del trabajo artístico que lleva a cabo el actor como ser comunicativo y expresivo. El análisis abarca desde las primeras investigaciones llevadas a cabo por los estudiosos del Círculo Lingüístico de Praga, donde la comprensión estructuralista de la creación actoral es de gran interés, hasta la teoría teatral posterior que plantea la actuación como un texto parcial dentro del texto espectacular creado a partir de un cuerpo en acción conformado por signos expresivos verbales y no verbales que el receptor-público debe descodificar.
Palabras clave: Actuación. Semiótica. Texto espectacular. Artes escénicas. Creatividad.
Abstract: This article focuses on the study of acting, the process of acting creation, from a semiotic perspective. The aim is to discuss and analyse the contributions that this scientific perspective has developed for the understanding of the artistic work carried out by the actor as a communicative and expressive being. The analysis ranges from the first research carried out by the scholars of the Linguistic Circle of Prague, where the structuralist understanding of the actor’s creation is of great interest, to the later theatrical theory that posits acting as a partial text within the performance text created from a body in action made up of verbal and non-verbal expressive signs that the receiver-audience must decode.

CARAS IDÉNTICAS. UNA TRAYECTORIA SEMIÓTICA
Authors: LEONE Massimo
Published: January 2025

Este artículo explora el uso poético de los espejos en la literatura argentina, centrándose en el cuento “La cara” de Silvina Ocampo y ampliando el análisis a obras de Macedonio Fernández, Julio Cortázar y Jorge Luis Borges. Los espejos se examinan como símbolos que reflejan e interrogan la identidad tanto literal como metafóricamente, situándolos dentro de una tradición exclusivamente argentina distinta del uso típico de los espejos en la literatura fantástica europea. Esta tradición muestra los espejos como herramientas de introspección y símbolos culturales que reflejan las complejas influencias europeas de Argentina y su búsqueda de una identidad única. El artículo también presenta una comparación innovadora entre los espejos literarios y los gemelos digitales, sugiriendo que los temas clásicos de la duplicación y el reflejo siguen siendo relevantes en los debates actuales sobre la identidad y la representación digitales. A través del análisis de las obras de Ocampo, Fernández, Cortázar y Borges, y del concepto de gemelos digitales, el artículo pone de relieve la persistente fascinación humana por los dobles como medio para navegar y comprender nuestras identidades tanto en espacios físicos como virtuales.
Palabras clave: Silvina Ocampo. Literatura argentina contemporánea. Espejos. Identidad. Autorreflexión. Gemelos digitales.
Abstract: This article explores the poetic use of mirrors in Argentine literature, focusing on Silvina Ocampo’s story “La cara” while also extending the analysis to works by Macedonio Fernández, Julio Cortázar, and Jorge Luis Borges. The mirrors are examined as symbols that reflect and interrogate identity both literally and metaphorically, positioning them within a uniquely Argentine tradition distinct from the typical use of mirrors in European fantastical literature. This tradition shows mirrors as tools of introspection and cultural symbols that reflect Argentina’s complex European influencesand its quest for a unique identity. The paper also presents an innovative comparison between literary mirrors and digital twins, suggesting that classical themes of duplicationand reflection remain relevant in current discussions of digital identity and representation.Through an analysis of the works of Ocampo, Fernández, Cortázar, and Borges, and theconcept of digital twins, the article highlights the persistent human fascination withdoubles as a means to navigate and understand our identities in both physical and virtualspaces.
Keywords: Silvina Ocampo. Contemporary Argentine literature. Mirrors. Identity. Selfreflection. Digital twins.
FICCIÓN INMERSIVA Y COSMOLOGÍA FRACTAL EN LAS SITCOMS GALÁCTICAS DE LAURA FERNÁNDEZ
Authors: GÓMEZ TRUEBA Teresa
Published: January 2025

En este artículo se analizan las estrategias ficcionales puestas en práctica por la novelista española Laura Fernández, autora de una amplia y original obra de ciencia ficción que, aun bebiendo en fuentes de una tradición pulp, retrofuturista y pop, adquiere una gran complejidad metaficcional y autorreferencial, así como un profundo efecto de extrañamiento en los lectores. Dicha complejidad tiene que ver con la creación de tramas que se disponen en una estructura en abismo de carácter especular, a partir de un principio de réplica a diferentes escalas. Para explicar ese sistema de construcción de relatos encadenados se recurrirá a las teorías científicas que describen el cosmos desde la geometría fractal, basado tanto en el principio de la autosemejanza como en la imprevisible irrupción del caos.
Palabras clave: Laura Fernández. Ciencia ficción. Mise en abyme. Fractal. Metaficción.
Abstract: This article analyses the fictional strategies put into practice by the Spanish novelist Laura Fernández, author of a wide-ranging and original work of science fiction that, despite drawing on sources from a pulp, retrofuturist and pop tradition, acquires great metafictional and self-referential complexity, as well as a profound effect of estrangement on readers. This complexity has to do with the creation of plots that are arranged in a specular abyss-like structure, based on a principle of replication at different scales. To explain this system of constructing linked stories, we will resort to scientific theories that describe the cosmos from fractal geometry, based both on the principle of self-similarity and on the unpredictable emergence of chaos.
Keywords: Laura Fernández. Science fiction. Mise en abyme. Fractal. Metafiction.
LA LUNA SUICIDA. EL CORPUS / CUERPO ULTRAÍSTA EN LA POESÍA DE LUCÍA SÁNCHEZ SAORNIL
Authors: NAVAS OCAÑA Isabel
Published: January 2025

Sánchez Saornil tenía ya, cuando se aventuró en las lides de Ultra, una amplia trayectoria como poeta modernista, de la que hubo de abjurar para abrazar el nuevo credo vanguardista. Las imágenes de destrucción, de muerte y de suicidio, que pueblan sus poemas en este período —la más significativa quizás sea la de la “luna suicida”—, evidencian que el tránsito no fue fácil, que la acucia el temor de no hallar esa nueva voz, y que, a pesar del sentimiento de pertenencia a la hermandad ultraísta, a pesar de su conexión con otros jóvenes poetas que, como ella, asumían el ingente reto de cambiarlo todo, quizás por su condición de mujer, no terminaba de encontrar un lugar en esta hermandad. Pues bien, estas circunstancias le confieren a la poesía ultraísta de Sánchez Saornil una singularidad excepcional dentro del movimiento Ultra.
Palabras clave: Lucía Sánchez Saornil. Modernismo. Ultraísmo. Vanguardias Feminismo.
Abstract: Sánchez Saornil already had, when she ventured into the work of Ultra, an extensive career as a modernist poet, which she had to renounce to embrace the new avant-garde creed. The images of destruction, death and suicide that populate her poems in this period —perhaps the most significant is that of the “suicidal moon”— show that the transition was not easy, that she was driven by the fear of not finding that new voice, and that, despite the feeling of belonging to the ultraist brotherhood, despite her connection with other young poets who, like her, took on the enormous challenge of changing everything, perhaps because of her condition as a woman, she could not find a place in this brotherhood. Well, these circumstances give Sánchez Saornil’s ultraist poetry an exceptional singularity within the Ultra movement.
Keywords: Lucía Sánchez Saornil. Modernism. Ultraism. Avant-garde Movements. Feminism.
