Abstract. It has become evident that additional metrics along the particle mass concentration, together with dense air quality monitoring networks within cities, are needed to understand the most efficient ways to tackle the health burden of particulate pollution. Particle lung-deposited surface area (LDSAal) is a metric to estimate particle exposure in the lung alveoli, and it has gained interest as a parameter for air quality monitoring as it is relatively easy and cost-efficient to measure with electrical particle sensors. Also, various studies have indicated its potential as a health-relevant metric. In addition to the electrical particle sensors, the LDSAal can be measured with various size distribution methods. However, different LDSAal measurement methods have fundamental differences in their operation principles, e.g., related to the measurement size ranges, size classification or conversion from the originally measured quantity into the LDSAal. It is not well understood how these differences affect the accuracy of the measurement in ambient conditions, where especially the particle effective density and hygroscopicity can considerably change the particle lung deposition efficiencies. In this study, the electrical particle sensor measurement (Partector) and two size distribution approaches (ELPI+ and DMPS/SMPS) were compared in road traffic environments with different environmental conditions in Helsinki and Prague. The results were compared by utilising the general assumptions of the LDSAal measurement (spherical hydrophobic particles with the standard density) and by evaluating the effects of the particle effective density and hygroscopicity. Additionally, the Partector and ELPI+ approaches were compared in various urban environments near road traffic, airports, river traffic and residential wood combustion. The results show that the comparison of different LDSAal measurement methods can be complicated in ambient measurements. The challenges were especially related to the accumulation mode particles roughly larger than 200–400 nm for which the dominant deposition mechanism in the lung changes from diffusion to impaction and the particle effective density and hygroscopicity tend to increase. On the other hand, the results suggest that the differences between the methods are reasonably low when considering only ultrafine and soot particles, which have an effective density closer to the standard (1.0 g cm−3) and are more hydrophobic, highlighting the suitability of the LDSAal as a monitored metric when estimating the spatial differences in the particulate pollution within cities.

Abstract. The “train effect” is defined as a cloud system in which several convective cells pass over the same place in a short time. Trains produce a large amount of rainfall, frequently leading to flash floods, reported mainly over North America during spring and summer. Thirty train events were identified using radar images calibrated by rain gauges for four winters, all associated with Cyprus lows (CLs). The dynamic factors responsible for their formation in Israel were examined, utilizing the ECMWF Integrated Forecast System with 0.1° resolution. Seventeen out of the 30 events share common features. Each one was found within the cold sector in the southern periphery of a CL at its occluded stage and located in the left flank of a maximum wind belt, where cyclonic shear vorticity exists. The trains cross the Israeli coast near 32.2° N, with a mean length of 35 km; last 2–3 h; and yield a total of 30–50 mm of rainfall. The maximum wind belts to the right of the trains were found to delineate the limit of the precipitative region of the CLs. Unlike classical trains, activated by thermal or frontal forcing, the eastern Mediterranean trains that develop in a cold air mass can be referred to as “cold trains” rather than the classical “warm trains”.

Authors: Caballa León Roberto R. , Quintanilla Melgar Dimas A.
Published: September 2024

La gerencia sustentable en la producción ovina es fundamental para asegurar la viabilidad a largo plazo de esta actividad ganadera, integrando beneficios ambientales, económicos y sociales. El manejo responsable de los recursos naturales, como el suelo y el agua, a través de prácticas como el pastoreo rotacional y la conservación de forrajes nativos, contribuye a la salud del ecosistema y previene la degradación ambiental. Tecnologías como la inseminación artificial, cuando se aplican de manera ética, pueden optimizar la genética y el rendimiento reproductivo, reduciendo la necesidad de intervenciones médicas. El presente estudio tiene como objetivo evaluar el impacto de prácticas de manejo sustentable en la eficiencia reproductiva y bienestar animal de ovejas criollas mediante la aplicación de protocolos de inseminación artificial a tiempo fijo utilizando gonadotropina coriónica equina (eCG) y progesterona (P4). El estudio es de tipo cuali-cuantitativo experimental con muestra de 248 ovejas criollas adultas, con variables de estudio: tasa de preñez y tasa de natalidad de la región Ayacucho, Perú. Los resultados indican que la gonadotropina coriónica equina (eCG) junto al tratamiento con progesterona (P4) induce celo-ovulación en ovejas criollas en anestro con alto porcentaje de preñez y natalidad. La capacidad de manipular el comportamiento reproductivo de las ovejas no solo mejora la tasa de preñez y prolificidad, sino que también contribuye a un uso más eficiente y responsable de los recursos naturales.

Published: September 2024

El presente artículo busca identificar los factores predictores de la conducta electoral en Colombia en las elecciones presidenciales de 2018. Para ello, fueron considerados aspectos como los factores sociodemográficos, el conocimiento de los procesos electorales y las actitudes y opiniones de los votantes sobre las elecciones y el sistema electoral. Se utilizó una metodología cuantitativa con información de segunda fuente proveniente de la Encuesta de Cultura Política del DANE (2019). La muestra fue de 19.461 adultos colombianos de todas las regiones del país y se llevó a cabo un análisis de regresión logística binaria. En los resultados se evaluaron 4 modelos de regresión logística con base en características sociodemográficas, percepción, actitudes y conocimientos sobre la democracia, que explican entre 2.5% y 7.5% de varianza. Se concluye que existen varios factores predictores de la conducta electoral como el género, estar desempleado, tener una discapacidad, simpatía partidista, tendencias de izquierda o derecha, entre otros. Sin embargo, llama la atención que la percepción de corrupción no tuvo un vínculo significativo con esta conducta.
Confianza en los medios de comunicación y libertad de prensa en el sur de Europa: diferencias entre países y perfiles sociodemográficos
Authors: Montiel Torres María Francisca , Zafra Arroyo Ana , Teruel Rodríguez Laura
Published: September 2024

Esta investigación plantea un estudio comparado de seis países del sur de la Unión Europea (Croacia, Eslovenia, España, Grecia, Italia y Portugal) analizando las características sociodemográficas sexo, edad, nivel de estudios e ideología para ver su influencia sobre la confianza en los medios de comunicación y establecer perfiles. A su vez, se propone comprobar si existe correlación entre la confianza y la libertad de prensa. Partiendo de los datos del Eurobarómetro y Reporteros Sin Fronteras, se emplea una metodología cuantitativa descriptiva y se testea su significación estadística. Salvo Portugal, todos los países presentan niveles de confianza bajos, especialmente Grecia. Las variables muestran gran heterogeneidad entre los territorios pero se prueba que mujeres, jóvenes y mayores, y quienes poseen estudios primarios muestran mayor confianza aunque, en algunos casos, con leves diferencias. Al contrario, confían menos quienes se definen de izquierda. Se observa una alta correlación entre libertad de prensa y confianza. A partir de los resultados, no puede considerarse que el sur de Europa sea un territorio uniforme en estos fenómenos.
From automata to algorithms: A jobs-to-be-done approach to AI in journalism
Authors: Hermida Alfred
Published: September 2024

Esta exploración del impacto de la inteligencia artificial (IA) en el periodismo establece paralelismos con los autómatas del siglo XVIII, rastreando una fascinación histórica por la vida artificial hasta las tecnologías de IA generativa actuales. Se discute cómo la IA está transformando las prácticas periodísticas, desafiando las nociones tradicionales de la profesión. En lugar de adoptar una posición binaria que enfrenta a humanos contra máquinas, se propone un marco de «tareas pendientes» para entender el papel de la IA en el periodismo. Este enfoque destaca cómo la IA puede servir mejor a las necesidades de las comunidades y las organizaciones mediáticas, alejándose de un enfoque centrado en qué tareas periodísticas pueden o no ser reemplazadas por la IA. Se sugiere un futuro híbrido en el que humanos e IA colaboren en el periodismo, con roles y responsabilidades que evolucionan según el trabajo a realizar para la industria, la profesión y el público
Columnismo y metacolumnismo en Antonio Muñoz Molina: la sección «Ida y vuelta» de Babelia (2007-2022)
Authors: Martín García Marta
Published: September 2024

La columna es el género más libre e impreciso del periodismo. En virtud de dicha libertad, los columnistas se presentan como protagonistas de sus propios textos e, incluso, la columna se convierte en el tema principal de la propia columna. Esta práctica da lugar a la metacolumna, una rareza periodística que no ha sido suficientemente estudiada. Este análisis se centra en el escritor Antonio Muñoz Molina y desentraña de qué forma, y con qué objetivos, el columnista habla y reflexiona sobre su propio trabajo. Para ello, se ha elegido una etapa completa del escritor en el periódico El País, la que abarca los textos publicados en el suplemento cultural Babelia durante 15 años. La muestra analizada está conformada por 731 columnas periodísticas publicadas por el autor desde octubre de 2007 hasta octubre de 2022. Los resultados del estudio muestran que, para Muñoz Molina, el artículo de opinión ha sido el marco vehicular con el que definir su propia columna, analizar su evolución como escritor o columnista, enumerar sus modelos y sus valores, establecer los límites deontológicos del género e incluso resolver conflictos con sus compañeros de profesión. Ello ha propiciado que el tema del columnismo, aunque a gran distancia de la literatura y del arte —los dos asuntos fundamentales en la muestra, pues protagonizan más del 65 % de los textos—, tenga una notable presencia, tanto cuantitativa como cualitativa, en el conjunto de las columnas analizadas.

The Integral Theory, Pelvic Floor Biomechanics, and Binary Innervation
Authors: Quaghebeur Jörgen , Petros Peter , Wyndaele Jean-Jacques , Wachter Stefan De
Published: September 2024

The pelvic floor biomechanics and sphincter functioning are essential for understanding pelvic floor dysfunction and the pathophysiology of the pelvic organs. The pelvic floor consists of muscles, fascial connections and ligaments. The Integral Theory Paradigm (ITP) explains the musculoskeletal entity of the sphincter mechanism and the pathophysiology of pelvic organ function. The ITP explains the pelvic floor function determined by 3 directional muscle forces: forward, backwards and downward-acting muscle vector forces that form an anterior and posterior resultant. The resultant equilibrium is essential for urinary continence, voiding and defecation. Loose ligaments disturb the equilibrium of the pelvic floor’s muscular function with consequences for the organ function’s continence, evacuation, and sensory perception.

Authors: Wright Sarah L. , Ananthavarathan Piriyankan , Simeoni Sara , Malladi Prasad , Pakzad Mahreen , Panicker Jalesh N.
Published: September 2024

Purpose: Nonneurogenic chronic urinary retention is an uncommon problem in young female individuals, and a well characterised causes is Fowler syndrome (primary disorder of urethral sphincter relaxation). Intermittent catheterisation is often challenging, and gold standard treatment sacral neuromodulation is not widely available. Urethral sphincter botulinum toxin injection has been shown to be effective cross-sectionally, however little is known about long-term outcomes.Methods: Female individuals presenting with urinary retention due to Fowler syndrome were reviewed retrospectively from a single tertiary referral centre over an 11-year period (2010–2021). One hundred units of onabotulinum toxin A (BoTX-A) was injected into the striated urethral sphincter in a divided dose by the periurethral approach. Efficacy and side effects were assessed 4 weeks after injection.Results: Thirty-three female individuals with a mean age of 40.1±14.1 years received 165 unique urethral sphincter BoTX-A injections over 11 years. Nineteen individuals (57.6%) presented in acute urinary retention, and 28 (84.8%) were reliant on catheterisation. Twenty-one individuals (64%) responded to BoTX-A injections and had a significantly raised baseline maximum urethral closure pressure (MUCP), compared to nonresponders (114.6 cm H2O, P=0.012). Side effects were reported following 19 injections (11.5%) however, were mild and transient. Fifteen individuals received more than 1 botulinum toxin injection (median, 3 injections), with a median interval of 112 days (interquartile range) and efficacy persisted following repeat injections and no safety concerns were seen.Conclusions: Sphincter botulinum toxin through the periurethral approach is safe and effective following repeat injections, and offers a low-cost, minimally invasive alternative to managing female chronic urinary retention due to Fowler syndrome, particularly when there was a high baseline MUCP.

Published: September 2024

Alpha-1 adrenergic receptor (α1-AR) antagonists are commonly used for management of benign prostatic hyperplasia or hypertension. Some studies have shown a potential link between α1-AR antagonist use and cognitive impairment. Given the conflicting data surrounding α1-AR antagonists association with cognitive dysfunction, we aim to systematically review the association of cognitive dysfunction with α1-AR antagonist use to aid clinician decision both with medication initiation and continuation. A systematic review was performed following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. We searched Ovid Cochrane, Ovid Embase, Ovid MEDLINE, Scopus, and Web of Science on March 7, 2023, with an update run on January 22, 2024. The primary outcome was cognitive dysfunction. We used Cochrane risk of bias for randomized controlled trials (RCTs) and MINORS (Methodological Index for Non-Randomized Studies) criteria for non-RCTs to evaluate study quality. This study was registered with PROSPERO (CRD42024505751). We identified 7 studies for our systematic review (3 RCTs, 4 non-RCTs). Tamsulosin was the most studied medication (6 of 7 studies). Tamsulosin was associated with no cognitive dysfunction in 2 RCTs, increased risk for dementia in 2 non-RCTs, no change in cognition in 1 non-RCT, and decreased risk for dementia in 1 non-RCT. Among 3 non-RCTs analyzing alfuzosin, it was associated with decreased risk of or no association with dementia in 2 studies and increased risk for dementia in 1 study. Doxazosin, prazosin, and terazosin were neutral or showed a negative risk for dementia. Our systematic review did not show a convincing causal association between α1-AR antagonists, including tamsulosin, and cognitive dysfunction. Considering the existing literature, it is appropriate to use α1-AR antagonists without concern for cognitive dysfunction. Future research, through robust study designs considering the multifactorial nature of cognitive dysfunction, is required to further evaluate this association.

Published: September 2024

The objective of this study is to investigate the relationship between environmental CO2 emissions and environmental determinants of green technology, foreign direct investment (FDI), energy efficiency, and economic growth (GDP) in Pakistan. The data uses the period 1995 to 2023. Utilizing the Autoregressive Distributed Lag (ARDL) technique, the results indicate a multifaceted relationship between these variables and environment CO2 Emissions. Green technology has a significantly positive impact on environmental CO2 emissions, through a 1 percent increase and a 1.12 percent decrease in environmental CO2 emissions. Additionally, foreign direct investment (FDI) shows a small but positive impact on environmental CO2 emissions, suggesting that even environmentally intensive investments may have unplanned consequences. Energy efficiency due to its robust effect has a positive impact on the environment's CO2 emissions. Finally, economic growth is found to positively influence environmental CO2 emissions. These results highlight the meaning of targeted policies to exploit the benefits of green technology and economic growth while carefully managing the impacts of foreign direct investment FDI and energy efficiency.

NITROGEN-CONTAINING SILANE COUPLING AGENTS: SYNTHESIS AND STRUCTURE EFFECT ON TIRE PERFORMANCE OF SILICA/SSBR/BR COMPOSITES
Authors: Oh Myong Joon , Kownacki Ireneusz , Janowski Bartłomiej
Published: September 2024

We report synthesis of nitrogen-containing silane coupling agents (N-SCAs) and their use in a 1:1 mixture by weight with bis(triethoxysilylpropyl)tetrasulfide preparation of silica/solution SBR (SSBR)/BR composites. These N-SCAs contain in their structures, inter alia, a tertiary amine center (N1, N2), a carbamate (N3), or a urea (N4) group. In addition, N1, N3, and N4 were equipped with allyl side arms to increase the hydrophobization effect of silica particle as well as to achieve a balance between the filler–filler and filler–matrix networks being formed. By contrast, N2 consists of glycidyl side arms that contribute to the filler–filler interaction even more. The silica/SSBR/BR blends and subsequent vulcanizates were prepared and then thoroughly investigated via dynamic mechanical analysis, rubber process analysis, and tensile testing. The composite based on N1 (V/N1) exhibited exceptionally great tensile strength, abrasion resistance, and winter traction, accompanied by soft hysteresis. Therefore, N1 has potential applications in preparation of winter tire tread materials.

Published: September 2024

In today's world, computer skills have become a necessity. However, there are differences between countries in the level of computer literacy of people in different age groups. In the long term, Finland achieves the best results in the level of computer literacy. The goal of the research study is to specify the differences in computer skills in Slovakia and Finland. The research is focused on people aged 50+. SHARE questionnaire - Survey of Health, Aging and Retirement in Europe was used to achieve the goal. The total number of observations was 2158. Chi-square (χ2) Test for Independence, Cramér's V and adjusted residuals were used to achieve the goal. Based on the methods used, we accepted the hypothesis that there is a significant association between countries (Slovakia and Finland) and computer skills. In Slovakia, there is a large share of people aged 50+ who have never used a computer. An approach by the government to promote expansion of access to the Internet, similar to Finland, could contribute to improving computer literacy in the Slovak Republic.

The aim of our scientific study was to identify and assess the specificities of the EU countries in the field of employment improvement based on the indicators “young people neither in employment nor in education and training” (NEET) and “employment rate” within the EU and to evaluate the position of the Slovak Republic. The selected indicators are determined in Agenda 2030 in the area of “Decent work and economic growth” as indicators with quantitative targets. In the scientific study, the method of analysis of the development of time series and linear regression analysis is used. We can say that the development in the Slovak Republic is favourable. However, the values of both indicators are worse than the average values in the EU. The linear regression points to a strong connection between indicators. From the derived relations, the possibilities for improvement also follow.

GREEN HUMAN RESOURCE MANAGEMENT PRACTICES IN THE CONTEXT OF SUSTAINABLE BUSINESS DEVELOPMENT
Authors:   Alexander Dubček University of Trenčín, Kráľová Katarína
Published: September 2024

Human resource management suggests that organizations that want to attract and in the future retain quality human resources for business with the goal of sustainable development must change the prevailing situation, especially now that human resources are consumed rather than developed. At the same time, green management of human resources was recently introduced as a response to changes at the social, economic and especially environmental level of the labor market and employment relations. Green human resources management is understood as an extension of strategic human resources management and represents a new approach to people management with a focus on long-term development, regeneration and renewal of human resources in the context of sustainable business development. However, the attributes of green HRM compared to mainstream HRM are not yet completely clear and precise. The contribution aims to fill this gap by proposing and revealing the characteristics of green human resource management and their impact and influence on business sustainability, as well as the possibilities of integrating green human resource management practices into businesses.

Published: September 2024

Today's small and medium-sized enterprises (SMEs) face many challenges associated with the implementation of artificial intelligence (AI), which offers a wide range of opportunities to improve efficiency, competitiveness and sustainability. Currently, there are a number of diverse factors affecting the operations of SMEs in Slovakia, and these factors can be divided into general ones, which affect SMEs regardless of the sector in which they operate, and specific ones, which take into account sector specificities. In the context of AI implementation, these factors are determined by the state of knowledge, the sector of AI implementation and the relationships of AI implementation to other environmental factors that determine the consequences. The aim of this paper is to explore the opportunities and challenges of AI implementation in Slovak SMEs, and based on the obtained information, to propose a framework for AI implementation in these enterprises. The conclusion of the article is that proper implementation of AI can help SMEs gain strategic advantage, but as it brings benefits it also brings risks that need to be faced.

Musa sp. (Banana) belongs to the Musaceae family, one the largest flowering plant cultivated throughout the world. Banana blossom (flower) commonly mentioned as heart of the banana, with a high nutrient content is consumed in Asian countries. This study was aimed to analyze the phytochemical constituents and to assess the antioxidant potential of methanol extract of banana blossom. Banana blossom was procured from the local market dried, powdered and extracted with methanol by cold percolation method.The presence of phytochemicals in the methanol extract of banana flower particularly alkaloids, flavonoids, phenols and terpenoids were analyzed using high performance liquid chromatography while, glycosides and saponins were analyzed by thin layer chromatography. The results revealed a higher concentration of flavonoids (1934 mcg/gm) followed by phenols (1545mcg/gm), glycosides (295.5mcg/gm), terpenoids (198.5mcg/gm) steroids (3.45mcg/gm), alkaloids (0.984mcg/gm), and saponins (0.33mcg/gm) in the methanol extract of banana blossom. The antioxidant activity (IC50) of the methanol extract of banana blossom was estimated to be 236.5µg/kg. Banana blossom extract could be considered as a potential nutraceutical and therapeutic agent with anticancer activity. However, further research (animal studies and clinical research) needs to be undertaken to ascertain the same.

The rhizomes of jahe merah (Zingiber officinale) and temu kunci (Boesenbergia rotunda) contain lots of flavonoids and phenolics. So far, Indonesian people have used Z. officinale and B. rotunda as a mixture of cooking ingredients and as traditional medicine that are known as "jamu". This research was conducted to determine the potential antioxidant activity rhizome extracts of Z. officinale (Zo), B. rotunda (Br) and their combination (Zo+Br) in mice exposed to Pb. Furthermore, it is also to determine the anticancer activity in the hepatocyte carcinoma cell line (HepG2). Twenty-five male mice were to divide into 5 treatment groups, namely P1 = control, P2 = Pb 100mg/mL, P3 = Zo 100mg/mL + Pb 100mg/mL, P4 = Br 100mg/mL + Pb 100mg/mL, P5 = combination Zo+Br (ratio 1:1) 100mg/mL + Pb 100mg/mL. Treatment was given for 30 days and on the last day the mice were anesthetized and sacrificed. Their livers were taken to observe histologically changes in hepatocyte morphology, MDA levels, as well as the activity of the antioxidant enzymes SOD and CAT. In vitro antioxidant activity was also tested using the DPPH assay and anticancer activity was tested on HepG2 cells. The results showed that range of antioxidant activity was in the strong to very strong because it has an IC50 value of Zo = 47μg/mL, Br = 67μg/mL and their combination (Zo+Br) = 100μg/mL. Treatment using Zo, Br and their combination can also prevent a significant increase in MDA levels and also significant decrease in SOD and CAT enzyme activity due to Pb administration. This is in line with the increase in normal cells and decrease in abnormal hepatocyte cells. In addition, administration of Zo, Br and their combination can inhibit the proliferation of HepG2 cells in the moderate cytotoxic range (IC50 value ranges from 42.97 to 86.94µg/mL). The conclusion of this research showed Z. officinale, B. rotunda and their combination have potential as antioxidants and can be used as drug candidates to inhibit the growth of cancer cells.
