Published: September 2024

Bu çalışmada, dolgu maddesi olarak kullanılan montmorillonit (MMT), iki farklı silan ajanı ((3- aminopropil)trietoksisilan (APTES) ve (3-glisidoksipropil)trimetoksisilan (GPTMS)) ile modifiye edilmiş, organik faz ile ara yüzey etkileşiminin arttırılması ve polimer matrisi içerisinde homojen bir şekilde dağılması sağlanmıştır. Polimer matris olarak ise biyobozunur ve biyouyumlu özelliklere sahip sentetik polimerlerden polikaprolakton (PCL) ve biyouyumlu ve hidrofilik özelliğe sahip polivinilpirolidon (PVP) birlikte kullanılmış ve çözelti döküm yöntemiyle biyomalzemeler üretilmiştir. Kemik doku mühendisliğine yönelik doku iskelesi olarak kullanımı ön görülen biyomalzemelerin morfolojik, fizikokimyasal ve mekanik özellikleri, atomik kuvvet mikroskobu (AFM), Fourier transform kızılötesi spektroskopisi (FT-IR), X-ışını difraktometresi (XRD), temas açısı analizi, su absorplama kapasitesi analizi ve mekanik analiz ile karakterize edilmiştir. AFM sonuçları, PCL/PVP polimer matrisinin 0,507 µm olan pürüzlülük değerinin modifiye edilmemiş MMT’nin eklenmesiyle 0,171 µm ve MMT-APTES eklenmesiyle ise 0,160 µm değerine düştüğünü göstermiştir. Pürüzlülük oranı en yüksek GPTMS ile modifiye edilmiş MMT katkılı biyomalzemelerde 0,530 µm olarak bulunmuştur. Temas açı değerleri ve su absorplama kapasiteleri karşılaştırıldığında, 68,4° ve 59,7° temas açı değerleri bulunan APTES ve GPTMS ile modifiye edilmiş MMT katkılı biyomalzemelerin, MMT katılmamış biyomalzemeden daha hidrofilik olduğu ve su absorplama kapasitesinin MMT katılmamış polimer matristen ve modifiye edilmemiş biyomalzemeden %125 ve %144 olarak daha yüksek olduğu görülmüştür. Sonuç olarak, ön değerlendirme niteliğindeki bu çalışmamız ile APTES ile modifiye edilmiş MMT katkılı PCL/PVP biyomalzemelerinin kemik doku hasarlarının tedavisinde doku iskelesi olarak kullanılabileceği ön görülmektedir.

A New Rank Estimator for Least Squares Estimation of Weibull Modulus
Authors: Birgören Burak
Published: September 2024

The Weibull distribution is widely used in reliability analysis to evaluate the failure behavior and lifetime characteristics of various systems and components. One of the most commonly used methods for estimating the parameters of the Weibull distribution is the ordinary least squares (OLS) technique, which is based on fitting a linear regression model to the transformed data. This paper proposes a new rank estimator for ordinary least squares estimation of Weibull modulus, a key parameter used as a measure of variability in the data. The new rank estimator is a quadratic function of the ranks of order statistics, with three parameters that are optimized by Monte Carlo simulations. Using relative efficiency as a criterion, the performance of the new rank estimator is compared with three commonly used rank estimators, mean, median and Hazen rank estimators, which are linear functions of the ranks of order statistics. The results show that the new rank estimator has a significant advantage over the other rank estimators for any sample size between 3 and 150. The findings also imply that other nonlinear functions, such as cubic polynomials, could be applied to further improve the efficiency of the parameter estimators of the ordinary least squares method.
СЕГРЕГАЦІЯ РОМІВ В СИСТЕМІ ОСВІТИ УГОРЩИНИ ТА СЛОВАЦЬКОЇ РЕСПУБЛІКИ
Authors: Годлевська Катерина
Published: September 2024

Стаття присвячена аналізу процесів шкільної сегрегації ромських дітей в освітніх системах Угорщини та Словацької Республіки, а також чинників, які впливають на її формування та підтримання. Актуальність теми дослідження сегрегації ромських дітей в освітніх системах Угорщини та Словацької Республіки полягає у її тісному зв’язку з проблемами соціальної ізоляції та дискримінації, які є викликом для багатьох країн Центральної та Східної Європи. Вивчення цього явища є важливим для розуміння механізмів соціальної селективності, що впливають на доступ ромів до якісної освіти. Метою дослідження є аналіз причин і чинників сегрегації ромських дітей в освітніх системах Угорщини та Словацької Республіки, а також порівняння підходів обох країн до вирішення цієї проблеми. Дослідження побудоване на аналізі літератури, документальних джерел і порівняльному підході. Проводився детальний аналіз наукових робіт провідних дослідників і офіційних звітів міжнародних організацій. Порівняння освітніх систем Угорщини та Словацької Республіки дало змогу ідентифікувати спільні та відмінні риси в організації освітнього процесу ромських дітей. Це дозволило виявити, наскільки різною є роль державної політики в управлінні процесами сегрегації. Отримані нові дані підтвердили, що сегрегація в обох країнах більше пов’язана з соціальним статусом, ніж з етнічною приналежністю. Основна гіпотеза полягає в тому, що соціально-економічні чинники є головною причиною сегрегації. У дослідженні використано метод аналізу літератури, порівняльний метод, а також аналіз документальних джерел. Проведено глибоке порівняння даних про освітні системи Угорщини та Словаччини, що дозволило виділити ключові чинники сегрегації. В результаті дослідження встановлено, що в Угорщині ключовим чинником сегрегації є соціальна селективність та політична підтримка приватних шкіл, що посилює нерівність доступу до освіти. У Словаччині виявлено, що головними проблемами є територіальна ізоляція ромських громад і недостатність державних заходів для запобігання сегрегації. Охарактеризо-вано основні освітні, соціальні та психосоціальні чинники, що впливають на процеси сегрегації. Теоретичне значення дослідження полягає в глибшому розумінні соціально-економічних та освітніх чинників сегрегації ромських дітей. Практичне значення полягає в тому, що результати дослідження можуть бути використані для розробки політик у сфері освіти для ромського населення. Оригінальність дослідження полягає в порівняльному аналізі двох освітніх систем, що дозволяє глибше зрозуміти процеси сегрегації. Висновки дослідження вказують на необхідність удосконалення державної політики щодо інтеграції ромських дітей. Подальші дослідження будуть спрямовані на аналіз впливу конкретних державних заходів на подолання сегрегації в інших країнах регіону.

Published: September 2024

This study aimed to compare the diagnostic accuracy and cost-effectiveness of musculoskeletal ultrasonography (US) versus magnetic resonance imaging (MRI) in detecting shoulder injuries. Conducted at the Department of Physical Medicine and Rehabilitation, BSMMU, Dhaka, Bangladesh, from January to June 2024, the study included 120 patients with suspected shoulder pathologies. Patients were evaluated using both US and MRI, and findings for rotator cuff tears, labral injuries, and tendonitis were analyzed. MRI demonstrated higher diagnostic accuracy across all conditions, with sensitivity rates of 95%, 91%, and 92% for rotator cuff tears, labral injuries, and tendonitis, respectively, compared to 88%, 79%, and 86% for US. Inter-rater agreement between US and MRI was substantial, with Cohen's Kappa coefficients of 0.75 for rotator cuff tears, 0.70 for labral injuries, and 0.73 for tendonitis. Cost-effectiveness analysis revealed that US was significantly more affordable, with an average cost of 15,000 Tk per patient compared to 60,000 Tk for MRI. Additionally, the time to diagnosis was shorter for US (2 days) than for MRI (7 days). Although US required slightly more additional interventions (13.3% vs. 8.3%), this difference was not statistically significant. The findings suggest that while MRI is more accurate, US is a cost-effective and time-efficient alternative, particularly valuable in resource-limited settings.

Authors: Baser Onur , Samayoa Gabriela , Yapar Nehir , Baser Erdem
Published: September 2024

Background: Although increasing in prevalence, nonalcoholic steatohepatitis (NASH) is often undiagnosed in clinical practice.

Objective: This study identified patients in the Veterans Affairs (VA) health system who likely had undiagnosed NASH using a machine learning algorithm.

Methods: From a VA data set of 25 million adult enrollees, the study population was divided into NASH-positive, non-NASH, and at-risk cohorts. We performed a claims data analysis using a machine learning algorithm. To build our model, the study population was randomly divided into an 80% training subset and a 20% testing subset and tested and trained using a cross-validation technique. In addition to the baseline model, a gradient-boosted classification tree, naïve Bayes, and random forest model were created and compared using receiver operator characteristics, area under the curve, and accuracy. The best performing model was retrained on the full 80% training subset and applied to the 20% testing subset to calculate the performance metrics.

Results: In total, 4 223 443 patients met the study inclusion criteria, of whom 4903 were positive for NASH and 35 528 were non-NASH patients. The remainder was in the at-risk patient cohort, of which 514 997 patients (12%) were identified as likely to have NASH. Age, obesity, and abnormal liver function tests were the top determinants in assigning NASH probability.

Conclusions: Utilization of machine learning to predict NASH allows for wider recognition, timely intervention, and targeted treatments to improve or mitigate disease progression and could be used as an initial screening tool.

RESUMO
Introdução: O artigo discute o crescimento das tecnologias médicas e seu impacto nas cirurgias, destacando a importância da gestão adequada de incisões para prevenir infecções do sítio cirúrgico (ISSC), uma complicação frequente que afeta de 2 a 5% das cirurgias. A adoção de abordagens como a recuperação aprimorada após a cirurgia (ERAS) visa minimizar incisões e focar nos cuidados pós-operatórios para melhorar a cicatrização e reduzir infecções. O uso de curativos evoluiu para materiais que, além de cobrir a ferida, também promovem a cicatrização e protegem contra infecções.
Metodologia: O estudo adotou uma revisão sistemática e meta-análise baseada em dados de 10 anos coletados de bancos como PubMed e LILACS. Focou em cirurgias de grande porte e práticas inovadoras, como o uso de curativos avançados e protocolos otimizados de esterilização. A pesquisa destacou a importância de equipes multidisciplinares, como cirurgiões e infectologistas, para uma prevenção eficaz de ISSC.
Resultados e Discussão: O processo de seleção rigorosa incluiu 150 estudos iniciais, sendo que 5 foram analisados em profundidade. A meta-análise revelou que curativos de silicone com vitamina E e mupirocina foram os mais eficazes na redução de ISSC. Embora outros curativos, como os à base de prata, não tenham mostrado eficácia significativa, a análise evidenciou a necessidade de mais estudos robustos para validar esses resultados, considerando fatores econômicos e clínicos.
Considerações Finais: O estudo conclui que, embora alguns curativos avançados mostrem eficácia na redução de ISSC, a falta de estudos com maior rigor metodológico e maior escala limita as conclusões. Futuros ensaios clínicos devem focar na escolha personalizada de curativos, considerando o tipo de cirurgia e as condições do paciente, além de investigar aspectos econômicos e o tempo ideal de uso. Isso poderá contribuir para o desenvolvimento de diretrizes mais eficazes para prevenir infecções em cirurgias de grande porte.

A Hipertensão Arterial Sistêmica (HAS) é uma condição multifatorial, definida como aumento persistente dos níveis pressóricos na ausência de medicações anti-hipertensivas. Tal qual possui riscos altos a evolução de complicações crônicas cardiovasculares, onde a evolução a alterações estruturais é permanente. A grande incidência desta patologia e o falho controle pelo Sistema Único de Saúde do Brasil (SUS) tornam suas complicações, como as cardiovasculares, um problema de saúde pública, necessitando assim gastos exorbitantes ao governo e sequelas longevas aos afetados. Partindo do princípio de que o tratamento da HAS visa reduzir os níveis sistólicos e diastólicos da pressão para valores inferiores a 140/90 mmHg, conforme as Diretrizes Brasileiras de Hipertensão Arterial, esta ação objetiva reduzir os riscos de morbimortalidade cardiovascular. Neste contexto, descrevem-se as principais complicações cardiovasculares como: Acidente Vascular Encefálico (AVE), Infarto Agudo do Miocárdio (IAM), Insuficiência Cardíaca (IC), Doença Arterial Periférica (DAP) e Doença Arterial Coronária (DAC). Conforme os dados notificados no DATASUS, observa-se que estas complicações representam 28% dos casos fatais com óbitos registrados, em relação a todos os grupos de causas no período de 2014 a 2023. Sugere-se então que os óbitos do país permaneçam a contrastar os avanços tecnológicos em saúde e as melhorias de qualidade de acesso aos serviços prestados à população, tornando-se um fato educacional e comportamental. Desta forma, referente aos dados analisados, a principal problemática da HAS ao desenvolvimento de eventos adversos cardiovasculares são a não adesão medicamentosa e tratamentos, sendo estes os principais desafios aonde em torne de 40% dos pacientes referem falha terapêutica. Por fim, o combate aos fatores de risco cardiovasculares, principalmente esta patologia de HAS, é de extrema importância para a prevenção de mortes.

Published: September 2024

Potassium (K) vertical mobility in soils has often been overestimated and used as a rationale for recommending the broadcast application of this nutrient in fertility management programs, especially in soils with low cation exchange capacity (CEC). This study aimed to evaluate the vertical distribution of K in two land uses: areas with natural vegetation and crop fields managed under no-tillage (NT) fertilized with K. For this purpose, 49 soil profiles from the Brazilian subtropical state of Rio Grande do Sul were sampled, comprising 45 profiles from areas under NT management and four profiles from sites with natural vegetation. Soil samples were collected in 19 very thin layers: 1 cm layer in the first 10 cm, 2.5 cm layer from 10 to 25 cm, and 5 cm layer from 25 to 40 cm. Sampling sites were then grouped according to their CEC, categorized as < 7.5, 7.6-15.0, and 15.1-30.0 cmol

. Both crop fields and natural fields exhibit a similar vertical gradient model, characterized by a strong accumulation of K in the soil within the uppermost centimeters. This gradient is notably enhanced by the addition of K fertilizers, leading to a substantial portion of K becoming inaccessible to the root system. The optimal level of available K for the topsoil soils was found within an average range of 4 to 12.5 cm of soil depth. Consequently, K fertilization resulted in two main outcomes: (i) an excess of K in the upper soil layers, which increases the potential for K loss through surface erosion and runoff, and (ii) a limited migration of K towards the deeper soil layers until reaching the root growth zone. There is an urgent need to: (a) reaffirm the official recommendations of public agencies that the replacement of K exported by crops should be carried out in the furrow, along the sowing line, and as deep as possible; and (b) reconsider the diagnostic soil layer for assessing the status of K availability in soils under NT management.
The Application of the Devil’s Advocacy Technique to Intelligence Analysis
Authors: Shewring Elianne
Published: September 2024

Understanding evolving situations and predicting future events are significant challenges in the intelligence sphere. These necessitate advanced techniques for intelligence collection and robust evaluation procedures to enhance the accuracy of predictions. The Devil’s Advocacy technique can be employed to improve analysis procedures by challenging prevailing views and mitigating the risk of cognitive biases. This paper examines the effectiveness of the Devil’s Advocacy technique when applied to intelligence analysis, by evaluating its strengths, weaknesses, and applicability, through a comprehensive literature review and empirical research involving experienced practitioners in New Zealand. Previous studies examining the Devil’s Advocacy technique primarily focused on its contribution to decision-making on the final intelligence product and on the perceptions of the devil’s advocate. However, this paper is also concerned with the analysts’ experience of practically applying the technique for intelligence analysis. This paper contends that the Devil’s Advocacy technique is an attractive complementary technique which is effective in specific situations. It also reveals that New Zealand intelligence practitioners define, perceive, and apply the Devil’s Advocacy technique differently across their organisations. It therefore argues that New Zealand practitioners may have an inconsistent understanding of the technique, indicating potential gaps in the training and education of New Zealand intelligence professionals. However, the inherently subjective nature of the technique itself could also be a contributing factor.

Published: September 2024

The spread of infectious diseases is a significant public health issue. Mathematical modeling is being used to find appropriate answers to this question. In this paper we propose a stochastic approach to compartmental models. A new model allows to rely on the fokker-planck equation with a SEIR model, with constant rates, to take into account the random environment in the propagation of a disease, markov and kolmogorov properties have been used in the modeling of the process. We have also determined the basic reproduction rate R0 of our new stochastic model using the new generation matrix.
On Equitable Colorings of Windmill Graphs
Authors: P Elumalai , A Parthiban
Published: September 2024

Let G be an undirected simple graph. Graph coloring is a special case of labeling, and G is said to admit a proper coloring if no two neighbouring vertices of it are given the identical color. The vertices of identical color constitute a color class. A graph is p-colorable if it has a p-coloring. The chromatic number of G, denoted by χ(G), is the minimum p such that G is p-colorable. A graph G is equitably p-colorable if it has a p-coloring and the absolute difference in size between any two distinct color classes is at most 1. The equitable chromatic number of G, denoted by χ=(G), is the minimum p such that G is equitably p-colorable. The equitable chromatic threshold of G, denoted by , is the minimum p ′ such that G is equitably p-colorable for all p ≥ p ′ . A windmill graph Wnm consists of m copies of the complete graph Kn, with every vertex connected to a common vertex. In this paper, we give exact values of χ=(G) and  when G is a windmill graph, bistar windmill graph, cycle windmill graph, and complete windmill graph.

Aim: The association of echocardiographic findings and subsequent risk of left-sided native valve endocarditis (LS-NVE) is undefined. The aim of this study was to determine if transthoracic echocardiography (TTE) measurements are associated with the subsequent development of LS-NVE in patients without cardiac predisposing conditions. Methods: Institutional databases were evaluated for adults diagnosed with LS-NVE from 2008 to 2020. Patients with prosthetic valves, cardiovascular implantable electronic devices, intracardiac devices, injection drug use, and predisposing cardiac conditions were excluded. Only patients who had a TTE performed 6 months to 3 years before the development of LS-NVE were included as cases. Controls were patients within the same Mayo location with a TTE report and were matched in a 1:3 ratio according to age, gender, Charlson comorbidity index, and echocardiography date. Results: There were 148 cases and 431 matched controls. As compared to controls, infective endocarditis (IE) cases had a higher prevalence of diabetes mellitus (46.6% vs. 30.4%) and chronic kidney disease (46.6% vs. 28.1%) (P < 0.001). Left ventricular outflow tract velocity (P = 0.017), left ventricular ejection fraction (P = 0.018), and E:e’ ratio (P = 0.050) were associated with LS-NVE. Conclusions: Echocardiographic measurements were associated with subsequent LS-NVE development in this pilot study. A larger cohort of LS-NVE patients, however, is needed to validate these findings.
Effects of Number of Filters and Frequency Cutoff in Continuous Interleaved Sampling and Frequency Amplitude Modulation Encoding Schemes in Cochlear Implant
Authors: Sari Lydia , Naud Mathieu , Alam Syah , Surjati Indra
Published: September 2024

Cochlear implants are devices designed to transform sound into electrical signals perceived by the brain, making them vital prostheses for deaf individuals. This study examines two schemes used in cochlear implants, namely Continuous Interleaved Sampling (CIS) and Frequency Amplitude Modulation Encoding (FAME), to compare their performance while varying the number of bandpass filters and cutoff frequencies used. Both schemes were simulated using 8 and 5 bandpass filters, and cutoff frequencies of 2000 Hz and 200 Hz. Results show that the CIS scheme can maintain signal intelligibility despite the loss of some frequency components when the number of bandpass filters is lowered. Conversely, FAME retains more frequency details but presents perceptible delays. With a cut off frequency of 200 Hz, signals processed with CIS loses intelligibility significantly, whereas FAME-processed signals remain intelligible both at 200 Hz and 2000 Hz cut off frequencies. It is therefore concluded that FAME can provide better cochlear implant performance despite the lower number of bandpass filters and lower frequency cutoff.

We investigate Coulomb drag resistivity in a double-layer system consisting of two parallel monolayer graphene sheets. In calculations, we employ the random-phase approximation to determine the polarizability functions of the graphene layers and the frequency-dependent dielectric function of the structure, taking into account inhomogeneity effects of the background dielectric. Our numerical calculations reveal that Coulomb drag resistivity in double-layer graphene systems steadily increases with increasing temperature but quickly decreases as the interlayer separation increases. The drag resistivity between the two layers in the case of an inhomogeneous background dielectric is substantially larger than that in the case of a homogeneous one. In addition, both the value and the imbalance in carrier density in the layers lead to noticeable changes in Coulomb drag resistivity in the system. Our study results are useful in graphene-based structure applications.
Functional brain connectivity changes associated with day-to-day fluctuations in affective states

Affective neuroscience has traditionally relied on cross-sectional studies to uncover the brain correlates of affects, emotions, and moods. Such findings obfuscate intraindividual variability that may reveal meaningful changing affect states. The few functional magnetic resonance imaging longitudinal studies that have linked changes in brain function to the ebbs and flows of affective states over time have mostly investigated a single individual. In this study, we explored how the functional connectivity of brain areas associated with affective processes can explain within-person fluctuations in self-reported positive and negative affects across several subjects. To do so, we leveraged the Day2day dataset that includes 40 to 50 resting-state functional magnetic resonance imaging scans along self-reported positive and negative affectivity from a sample of six healthy participants. Sparse multivariate mixed-effect linear models could explain 15% and 11% of the within-person variation in positive and negative affective states, respectively. Evaluation of these models’ generalizability to new data demonstrated the ability to predict approximately 5% and 2% of positive and negative affect variation. The functional connectivity of limbic areas, such as the amygdala, hippocampus, and insula, appeared most important to explain the temporal dynamics of affects over days, weeks, and months.

This study employs a descriptive-comparative method to compare two main strategies, namely Digital PR and Digital Marketing, implemented in the environment of Universitas Terbuka Semarang. Data were collected through interviews with university staff involved in the implementation of both strategies, document analysis, and observation of university practices. The Digital PR strategy at UT Semarang focuses on building a positive image through social media, online news platforms, and blogs, while the Digital Marketing strategy emphasizes paid advertising, paid social media, and email campaigns to prospective students. The integration of both strategies was then evaluated to determine the resulting outcomes, revealing that the combined strategies generated a consistent and robust narrative that enhanced the conversion of prospective students into new students. Despite positive outcomes, the study identified challenges such as the expansion of resources and workforce needed to execute effective digital campaigns. The research subjects were twelfth-grade students at SMA N 1 Ungaran who were active on social media with over 1,000 followers, selected using purposive sampling techniques. Three students were chosen as research subjects because they were considered potential influencers in the Ungaran area.

This scientific paper aims to find out the politics of identity and multiculturalism contained in the film ‘Tenggelamnya Kapal Van Der Wijck’. This research analyses identity politics and multiculturalism in the film ‘Tenggelamnya Kapal Van Der Wijck’. Through in-depth analysis, it is found that social inequality in Minangkabau society is an important factor influencing the dynamics of this film. Identity politics emerges through the concepts of treasure and custom that dominate social interactions, where power and social status become the main determinants in decision-making, especially in relationships between characters. The film also reflects Bugis cultural values, such as loyalty and honour, which become the foundation for the main character in facing life's challenges. In addition, multiculturalism in this film can be seen from the representation of Minangkabau culture, acculturation with Western culture, and the prominent social differences between the main character who comes from Makassar and the Minangkabau community. In conclusion, this film confirms that identity politics and multiculturalism play a significant role in shaping the narrative and dynamics between characters, and reflects the cultural complexity that exists in Indonesian society.
