Authors: Deniz Kübra , Akıncı Cosgun Aysegul
Published: December 2024

The study examined whether the perceptions of competence of preschool teachers working in kindergarten classes of primary schools and independent kindergartens under the Ministry of National Education in Adana province regarding literacy preparation activities varied according to the variables of teachers' age, gender, professional seniority, type of school worked in, and the age group of the children the teachers worked with. The sample of the study consisted of 332 preschool teachers working in independent kindergartens affiliated with the Ministry of National Education and kindergarten classes affiliated with primary schools located within the borders of Adana province's Center, Çukurova, Seyhan and Yüreğir districts in the fall semester of the 2020-2021 academic year. SPSS (Statistical Package for the Social Sciences) 23.0 package program was used in the statistical analysis of the data. Categorical measurements were summarized as numbers and percentages, and continuous measurements were summarized as mean and standard deviation (median and minimum-maximum where necessary). The skewness and kurtosis values of the scale scores were examined in order to determine whether the parameters in the study showed a normal distribution. In the normally distributed parameters, independent student t-test was used in the two-group analysis, and Oneway ANOVA test was used in the analysis of more than two groups. In the case of variables with more than two groups, Tukey test was used as a Post Hoc test to determine the source of the difference between the groups. Pearson and Spearman’srho correlation tests were used to determine the relationship between the scales. The statistical significance level was taken as 0.05 in all tests. Suggestions were made based on the research findings and findings.

Authors: Tehreem  , Garg Harish , Ayaz Kinza , Emam Walid
Published: December 2024

The Choquet integral is a fuzzy measure that serves as an effective aggregation operator for combining a limited number of components into a single set. In 1978, Hamacher introduced the Hamacher t-norm and t-conorm, an expanded version of algebraic t-norms. In this article, we present the aggregation operators for the Choquet integral that utilize the Hamacher t-norms to handle the theory of complex intuitionistic fuzzy values. These operators include the complex intuitionistic fuzzy Hamacher Choquet integral averaging and geometric operators. Additionally, an analysis is conducted on the attributes and special situations of the suggested methodologies. In addition, a novel approach is presented, utilizing newly developed operators for solving multi-attribute decision-making issues with complex intuitionistic fuzzy values. The operational stages of this strategy are thoroughly presented. Finally, we conducted a comprehensive comparison between the proposed methodology and existing approaches, using illustrative examples to validate the effectiveness and demonstrate the advantages of the proposed methods.

Published: December 2024

Introduction:

Kinase anchor protein 12 (AKAP12) has been widely studied and confirmed as a tumor suppressor in various cancers. However, its immune effects on gastric cancer have not been clarified. Therefore, we systematically analyzed the role of AKAP12 from multiple aspects of immunity using imaging genomics technology. In addition, we combined machine learning techniques to build and screen the best model for predicting gastric carcinogenesis. In conclusion, our study provides strong evidence that AKAP12 is closely related to tumor immunity in gastric cancer from multiple aspects, which supports the innovation of precision cancer management.

Objective:

Exploring the effect of AKAP12 gene expression on immunity and survival in gastric cancer.

Materials and Methods:

Relevant imaging genomics technology was used to analyze the mRNA data related to gastric cancer in The Cancer Genome Atlas database to study and evaluate the relationship between AKAP12 expression and tumor immunity. The best model for predicting gastric carcinogenesis was established and screened by using machine learning jointly.

Results:

AKAP12 is lowly expressed in gastric cancer and negatively correlated with its methylation. High expression of AKAP12 is positively correlated with survival time and a variety of immune-related genes and pathways. AKAP12 is also significantly correlated with relevant immune cell subpopulations in the tumor microenvironment. The Naive Bayesian Classification model is the best model to predict the expression level of AKAP12, which can better predict the risk of gastric cancer and the expression level of the gene, and realize the personalized and precise treatment of tumors.

Conclusion:

This study reveals the important role and significance of the AKAP12 gene in gastric cancer and discovers a simple, noninvasive, imaging genomics prediction model that can predict the expression level of the AKAP12 gene.
Pharmacist-Led Intervention on Medication Adherence and Its Impact on Health-Related Quality of Life and Preventing Acute Events Among Diabetic Patients: A Narrative Review
Authors: Yousif Osman , Osman Ibrahim , Yousif Mirghani
Published: December 2024

Globally, the increase in type 2 diabetes mellitus (T2DM) prevalence and related complications underscores the critical need for effective management strategies. Although various medications are available, the challenge of medication adherence remains prominent among patients. This review investigates the effects of pharmacist-led interventions on medication adherence, health-related quality of life (HRQoL), and the prevention of acute events in T2DM patients. A comprehensive literature search was conducted using Google Scholar and the PubMed database, focusing on studies published in the last decade that examined pharmacist-led interventions specifically targeting adherence, HRQoL, and acute events. The findings reveal that pharmacist-led interventions have a beneficial impact on enhancing medication adherence, improving HRQoL, and decreasing the incidence of acute events for individuals with T2DM. These interventions contribute to better medication knowledge, address patient inquiries and concerns, and offer personalized support tailored to individual patient needs. Consequently, pharmacist-led initiatives play a vital role in the effective management of T2DM, helping to minimize acute events and improve overall patient outcomes. Future research should delve into identifying specific barriers to medication adherence, and to the development of tailored interventions that can address these challenges. Additionally, it is essential to evaluate clinical, humanistic, and economic outcomes associated with these interventions. Moreover, innovations in medication design, particularly those that decrease dosing frequency, could further enhance adherence rates and optimize glycemic control in patients living with T2DM.

Authors: Khedr Wael E. , Elashmawy Hesham , Alawady Samir , Attia Ashraf E. , Salama Samir R. , Helmy Eman D. , Mahmoud Ahmed E.
Published: December 2024

Background:

Diastolic dysfunction is common in patients undergoing coronary artery bypass grafting (CABG). This study investigates the effects of ivabradine, a selective inhibitor of the cardiac pacemaker current (If), on diastolic function following CABG.

Materials and Methods:

This prospective cohort study included sixty adult patients with coronary artery disease and preserved systolic left ventricular function but with diastolic dysfunction (DD). Patients were randomly assigned into two groups: Group I received standard postoperative medical therapy with ivabradine (5.0–7.5 mg BID), initiated early after surgery, whereas Group II received standard postoperative medical therapy alone. Exclusion criteria included those having concomitant valvular or pericardial disease, atrial fibrillation, and contraindications to ivabradine. Echocardiographic parameters, including left atrial dimensions, filling velocities, tissue Doppler imaging, and deceleration time, were assessed preoperatively, at 7 days postoperatively and at 90 days.

Results:

Group I exhibited significant reductions in blood pressure and hematocrit levels and elevated levels of creatine kinase-MB and LDH, along with reductions in left atrial volume, aortic diameter, and right ventricular diameter, whereas Group II showed decreased platelet counts, ejection fraction, and isovolumic relaxation time; an improvement in diastolic function, and lack of tendency toward normalization of DD.

Conclusion:

The addition of ivabradine to standard postoperative therapy may enhance diastolic function in patients post-CABG surgery. Further prospective studies with larger cohorts are warranted to confirm these findings.
Effect of Abdominal Girth and Vertebral Column Length on the Spread of Spinal Anesthesia with Fixed-dose Plain 0.5% Levobupivacaine
Authors: Mahendru Kiran , Wadhwa Bharti , Saxena Kirti Nath
Published: December 2024

Background:

The spread of spinal anesthesia can be unpredictable and is influenced by various factors. A high spinal block increases the incidence of hemodynamic instability and duration of hospital stay, whereas a low level of block may result in inadequate surgical anesthesia. It has been hypothesized that body shape metrics in terms of abdominal girth (AG) and vertebral column length (VCL) influence the spread of local anesthetic within the subarachnoid space and the level of sensory block achieved. We explored the effects of AG, VCL, and their ratio on the level of sensory block achieved after the administration of a fixed dose of levobupivacaine.

Methods:

Fifty patients, ASA Grade Ι-ΙΙ, from 18 to 60 years of age scheduled for elective lower abdominal, pelvic, or lower limb surgery were enrolled in this observational study. Weight, height, body mass index (BMI), AG, and VCL were recorded preoperatively. Subarachnoid block was administered with 3 ml of 0.5% plain levobupivacaine in all patients using a standard 25G Quincke needle in lateral decubitus position through midline approach at the L3L4 intervertebral space. The correlation between the maximal sensory level of the block and physical parameters was analyzed using the Spearman rank correlation coefficient.

Results:

The parameters were statistically correlated with maximal sensory block by Spearman rank correlation coefficient (r) using linear regression analysis. The correlation of age (r = 0.076 and P = 0.601), height (r = −0.049 and P = 0.737), and VCL (r = −0.046 and P = 0.753) of the patient to the maximum level of sensory block achieved was not statistically significant. Whereas, the weight (r = 0.43 and P = 0.002), BMI (r = 0.452 and P = 0.001), AG (r = 0.662 and P ≤ 0.001), and the ratio VCL/AG2 (r = −0.673 and P ≤ 0.001) had statistically significant correlation with the level of sensory block achieved at 30 min after the administration of 3 ml of 0.5% plain levobupivacaine.

Conclusion:

VCL/AG2 which simulated the ratio of long axis and the transaction area of abdomen may help anesthesiologists choose the proper local anesthetic dose for the subarachnoid block to achieve appropriate surgical anesthesia.
Comparative Evaluation of Sequential Organ Failure Assessment Score Alone versus Sequential Organ Failure Assessment Score with Procalcitonin in Outcome Prediction among Intensive Care Unit Patients with Sepsis
Authors: Kalra Priyanka , Kerai Sukhyanti , Gupta Lalit , Chaudhary Kapil , Goswami Binita
Published: December 2024

Background:

In critically ill patients with sepsis, it is essential to implement risk stratification and targeted interventions to enhance their prognosis. In the present study, we aimed to ascertain the discriminatory accuracy of Sequential Organ Failure Assessment (SOFA) score, serum procalcitonin (PCT) levels, and their combination for predicting the short-term mortality of patients with sepsis.

Methodology:

This prospective observational study was undertaken on 40 patients with sepsis requiring intensive care unit (ICU) admission. SOFA score and PCT levels were measured at the time of ICU admission and at 48 h later. Based on these values, the delta SOFA and PCT clearance were calculated. All the patients were provided standard institutional ICU care, and they were followed up to 14 days after ICU admission.

Results:

We found that 21 were survivors (52.5%) and 19 (47.5%) were nonsurvivors. The area under the curve (AUC) for SOFA scores at ICU admission and at 48 h is 0.704 and 0.771, respectively, suggesting fair accuracy for mortality prediction. The PCT level at ICU admission has fair accuracy (AUC = 0.739), whereas at 48 h, it has shown improved accuracy with an AUC of 0.812. Assessment of patients at these study intervals by combining SOFA scores and PCT levels resulted in AUC of 0.704 and 0.839, respectively.

Conclusion:

The ability of SOFA score at 48 h after ICU admission to predict the short-term mortality of patients with sepsis is improved by combining it with PCT levels; however, the performance of this combination is not better than PCT levels alone.
Esophageal Squamous Cell Carcinoma Causing Nonbacterial Thrombotic Endocarditis
Authors: Batra Nitish , Acharya Sourya , Kumar Sunil , Shukla Samarth , Gupta Anusha
Published: December 2024

The illness known as nonbacterial thrombotic endocarditis (NBTE) is characterized by the deposition of fibrin and thrombi on deteriorated or normal heart valves without microbes. Compared to infective endocarditis, this disease is more frequently observed in chronic inflammatory conditions and is linked to a higher incidence of thromboembolic events. Vegetations on two-dimensional echocardiography and negative blood cultures suggest the disease. It is generally associated with advanced malignancies and very rarely with squamous cell carcinoma (SCC) of the esophagus. Here, we describe the case of a 68-year-old female with SCC of the esophagus who developed NBTE.
Left Ventricular Assist Devices – Past, Present, and Future: A Narrative Review
Authors: Kumar Devesh , Seth Sandeep , Narang Rajiv
Published: December 2024

Advanced heart failure (AHF) is a major problem with an aging population and profound unmet needs. While heart transplant offers the most definitive solution, it is largely unavailable for most and mandates a long waiting period. Left ventricular assist devices (LVADs) help in expanding the treatment armamentarium to those for whom transplant is either a contraindication or unavailable (destination therapy) and those who need stabilization before transplant (bridge to transplant). LVADs are truly a renaissance in the management of AHF as they make treatment available to a much larger population and improve not only symptoms and quality of life but also survival as compared to patients on medical therapy only. Consequently, they have now been adopted in many European centres as destination therapy with a median survival of 7 years in patients with a LVAD implantation. LVADS are plagued with multiple complications, and while they do offer an opportunity of improved survival, the patients often are plagued with morbid complications. Newer advances in technology have paved the way for smaller and better engineered devices with lesser complications like bleeding and pump thrombosis. We review briefly the burden of advanced Heart Failure, evolution of LVADs, current status and the future of these devices.

Persistent pain in maxillary premolars following root canal treatment with apical transportation: A report of two cases without periapical pathology
Authors: Ong Teng Kai
Published: December 2024

Persistent pain after endodontic treatment is often associated with evidence of periapical pathology. Nonetheless, this case report presents two instances of persistent pain in maxillary premolars post root canal treatment (RCT), without evident periapical radiolucency on imaging. A 35-year-old Asian female experienced dull, aching pain on biting in tooth #25, whereas a 40-year-old Caucasian female reported similar symptoms in tooth #15. Both teeth showed tenderness to percussion but not palpation. Periapical radiographs and cone-beam computed tomography (CBCT) scans revealed completed RCT with apical transportation but no detectable periapical pathology. Thus, both teeth were diagnosed as previously treated with symptomatic apical periodontitis. Non-surgical retreatment successfully addressed untreated canal spaces, resolving symptoms. This report suggested persistent pain following RCT might stem from endodontic reasons, even in the absence of visible apical pathology on CBCT scans, highlighting the importance of thorough canal debridement to resolve symptoms associated with untreated canal spaces in apical transportation. Furthermore, this case report demonstrates that clinicians should make a diagnosis through thorough dental history and other clinical investigations, without relying solely on CBCT for the diagnosis of posttreatment endodontic pain.
Agreement between students’ self/peer and faculty assessments of the radiographic technical quality of root canal treatment performed during preclinical and clinical endodontic courses
Authors: Awooda Elhadi Mohieldin , Elzaki Wail Mohammed , Al-Nazhan Saad Abdulaziz
Published: December 2024

Introduction:

This study investigated the agreement between students’ self-assessment or peer assessment and faculty assessment of the quality of root canal treatment (RCT) performed during preclinical and clinical endodontic courses.

Materials and Methods:

This cross-sectional study enrolled 23 4th-year students and a faculty member from the University of Medical Sciences and Technology, Sudan. The radiographic technical quality of RCTs performed during preclinical and clinical endodontic courses was evaluated by the students themselves, their peers, and faculty members in terms of the obturation length, shape, and density. Paired Student’s t-test was used to compare self-peer and faculty assessments. P < 0.05 was considered indicative of statistical significance.

Results:

No statistically significant differences were observed among the three assessment groups in terms of the quality of RCTs performed during the preclinical course. However, statistically significant differences were observed between self- and peer assessments (P = 0.014), and between self- and faculty assessments (P = 0.005), which may be attributable to lower confidence among students when working on real patients, leading to lower self-assessment scores.

Conclusion:

Significant differences were observed between self- and peer assessments and faculty assessments in the quality of RCT performed during the clinical course, with students underrating their performance. Formative assessment of learning rather than summative assessment, during endodontic courses, is recommended at the end of academic year.

Authors: Ikhile Favour Osasenaga , Enabulele Joan Emien
Published: December 2024

Introduction:

Dental trauma could lead to separation or crushing of the dental supporting tissues and esthetic and functional disorders. This study aims to evaluate the knowledge regarding the management of dental trauma among clinical dental students and interns in Benin City, Nigeria.

Materials and Methods:

This descriptive cross-sectional study utilized a self-administered questionnaire containing 15 closed and open-ended questions to garner data focused on sociodemograhic characteristics and awareness of the management of traumatic dental injury, from respondents. Data from 95 respondents were statistically analyzed and both univariate and bivariate analyses were used in this study.

Results:

A significant proportion; 77 (81.1%) had a poor overall knowledge of management, although most respondents had knowledge of some of the steps involved in emergency management of dental trauma. The association between respondents’ level of education and their knowledge of the management of dental trauma was found to be statistically significant (P = 0.0001). Respondents at higher level in their dental training were found to have better overall knowledge compared to those at lower levels.

Conclusion:

The knowledge regarding the management of dental trauma among the respondents was poor. This was associated with the level of study and clinical exposure.

Authors: Khatri Ankita , Jaiswal Amit , Joshi Amit , Parate Tilottama
Published: December 2024

INTRODUCTION:

Acute ischemic stroke (AIS) is a significant disease burden globally. However, its association with raised serum uric acid (SUA) levels remains controversial. Thus, we evaluated the uric acid level in the first episode of AIS and assessed the association of SUA levels with the severity of AIS and functional disability produced.

MATERIALS AND METHODS:

This single-center, case–control study was performed in the Department of Medicine of a tertiary care institute, over a period of 24 months. Cases included patients with the first episode of AIS proven on computed tomography or magnetic resonance imaging. SUA levels were estimated in cases (n = 50) and matched controls (n = 50) within 24-h of admission. Among cases, the severity of stroke was assessed by the National Institutes of Health Stroke Scale (NIHSS) score, and a modified Ranking Score (mRS) was used for evaluating the disability.

RESULTS:

Hyperuricemia was present in 88% of cases. The mean SUA levels were significantly higher among cases relative to controls (7.78 ± 1.26 mg/dl vs. 5.24 ± 1.18; P < 0.0001). Based on the NIHSS score and mRS, most of the patients had a severe stroke (56%) and moderate functional disability (40%), respectively. Among cases, SUA levels had a moderate and significantly positive correlation with NIHSS score (r = 0.527, P < 0.0001), and mRS (r = 0.533, P < 0.0001). However, SUA levels were not significantly associated with comorbidities, including diabetes mellitus, hypertension, obesity, and ischemic heart disease (all P > 0.05).

CONCLUSION:

Hyperuricemia is highly prevalent among patients with AIS, and it is positively and significantly correlated with NIHSS score and mRS.
“Vsaj En Stavek Povej Normally”: Anglicisms and Code-Switching in Slovene Youth Slang
Authors: Košmrlj Lea
Published: December 2024

The influence of the English language can be observed, to a greater or lesser extent, in virtually every world language, and is recognizable in language contact phenomena like borrowing and code-switching. To date, there has been limited research on the widespread use of English in the language of young speakers of Slovene, who encounter English on a daily basis both through education and entertainment. The present study aims to address this research gap by examining the linguistic behaviour of young adult native speakers of Slovene in their everyday informal communication. Drawing on methods of discourse analysis, we quantitatively and qualitatively analyse corpus data obtained through covert audio recording, exploring how the Slovene-English language contact manifests itself in everyday communication among young speakers of Slovene, with close attention paid to code-switching and anglicisms. The results of the study raise the question of language change and the future of languages like Slovene, whose speakers are in close contact with English every day, and suggest further research possibilities in the field of Slovene-English language contact.
Migrant Voices in the Plurilingual Poetry and Creative Practice of Fióna Bolger
Authors: Stępień Aneta
Published: December 2024

This article investigates the responses of Irish contemporary poetry to transnational migration and the attempts of poets to build empathetic connections with migrants and refugees, who face increasing violence across the European continent and beyond. More specifically, the article examines the centrality of this theme in the work of Fióna Bolger (b. 1972), whose plurilingual poetry and work in the field of creative facilitation demonstrate efforts to connect different cultures, languages and marginalized communities. Bolger’s anti-racism and trauma informed creative practice, discussed in detail in the article, speaks to the power of poetry to create solidarity across various communities and as such may provide a valuable model for artsbased participation in other contexts. The article argues that her work exemplifies decolonial sensibilities (Phipps 2019) that resist the homogenizing views of national literatures as bound by one nation and language, thus escaping narrow understandings of what constitutes Irish and European writing.
Musical Form as a Framing Device: Absolute Music and Desiderius a Dó [The Second Desiderius] by Pádraig Ó Cíobháin
Authors: De Brún Sorcha
Published: December 2024

This paper undertakes a close reading of European classical music forms used as a framing device in the Irish language novel Desiderius a Dó (1995) by Pádraig Ó Cíobháin. Considered one of the seminal novels of modern Irish, Ó Cíobháin’s work contains what the scholar Irina Rajewsky describes as “intramedial references to visual arts, music, cinema, literature and architecture”. Classical music occupies a central place in the novel, and is essential for an understanding of its plot, characterization, narrative and its thematic concern with ideas of binaries and performance. The paper examines absolute music forms characteristic of the classical period in the novel, explores how Ó Cíobháin uses liturgical music and chant, and concludes that the overall effect of the writer’s approach is a reimagination of the Irish language novel within a European frame that is remarkable for the depth and scope it gives the characters and the narrative.

Published: December 2024

Bu çalışma, tasavvuf düşüncesinde önemli bir yere sahip olan sefer kavramını, sûfîlerin manevî eğitim yöntemi olarak bu kavramı nasıl değerlendirdiğini ve bu yöntemin tasavvufî eğitimdeki yerini incelemektedir. Hicrî 6. asra kadar olan dönemde sûfîlerin yazılı eserlerine dayanarak seferin nefis terbiyesi, içsel dönüşüm ve Allah’a yakınlaşma amacı taşıyan bir yöntem olarak tasavvufta nasıl bir rol oynadığı analiz edilmiştir. Sefer, sûfîler tarafından bir yolculuk şeklinde ele alınmakla birlikte yalnızca fiziksel değil, aynı zamanda içsel bir dönüşüm aracı olarak da görülmüştür. Çalışmada seferin, nefis terbiyesi, manevî yükseliş ve Allah’a yakınlaşma amacı taşıyan bir yöntem olarak değerlendirilmesi, sûfîlerin bu yolculuğa atfettiği farklı anlamlar ve uygulama biçimleri analiz edilmektedir. Araştırmanın kapsamı, sefer kavramının tasavvuf tarihinde hicrî 6. yüzyıla kadar örneklem kabul ettiğimiz sûfî-müelliflerden hareketle geçirdiği dönüşümleri ve sûfîler arasında seferin kabul görme veya reddedilme gerekçelerini incelemektedir. Örneklem olarak seçilen müellifler tasavvuf klasiklerini yazan sûfîlerden oluşmaktadır. Çalışmada, tasavvuf tarihinde maddî ve manevî olarak sefer ayrımı olduğu, maddî seferlerin ilmî yolculuk, ibadet, şeyh ve âlim ziyaretleri gibi pratiklerde; manevî seferin ise seyr ü sülûk olarak adlandırılan nefisle mücadele ve içsel arınma süreçlerinde olduğu gözlemlenmiştir. Çalışmanın sonucunda seferin, sûfîlerin bireysel gelişimde ve nefis terbiyesinde sistematik bir yöntem olarak kabul edildiği; bununla birlikte sûfîler arasında yöntemin zorunluluğu konusunda farklı yaklaşımların bulunduğu ortaya konulmaktadır.
Worst-Case Input Generation for Concurrent Programs under Non-Monotone Resource Metrics
Authors: Pham Long , Hoffmann Jan
Published: December 2024

Worst-case input generation aims to automatically generate inputs that exhibit the worst-case performance of programs. It has several applications, and can, for example, detect vulnerabilities to denial-of-service (DoS) attacks. However, it is non-trivial to generate worst-case inputs for concurrent programs, particularly for resources like memory where the peak cost depends on how processes are scheduled. This article presents the first sound worst-case input generation algorithm for concurrent programs under non-monotone resource metrics like memory. The key insight is to leverage resource-annotated session types and symbolic execution. Session types describe communication protocols on channels in process calculi. Equipped with resource annotations, resource-annotated session types not only encode cost bounds but also indicate how many resources can be reused and transferred between processes. This information is critical for identifying a worst-case execution path during symbolic execution. The algorithm is sound: if it returns any input, it is guaranteed to be a valid worst-case input. The algorithm is also relatively complete: as long as resource-annotated session types are sufficiently expressive and the background theory for SMT solving is decidable, a worst-case input is guaranteed to be returned. A simple case study of a web server's memory usage demonstrates the utility of the worst-case input generation algorithm.

Published: December 2024

Esnek gerinime duyarlı elektro-eğirilmiş lifli katmanlar, geniş yüzey alanları ve olağanüstü esneklikleri nedeniyle araştırmacıların geniş ilgisini çekmiştir. Burada, elektro-eğirme parametrelerinin, elektro-eğirilmiş çok duvarlı karbon nanotüpler (ÇDKNT)/termoplastik poliüretan (TPU) nanoliflerinin morfolojik ve elektromekanik özellikleri üzerindeki etkisi üzerine ayrıntılı bir araştırma yürütülmüştür. ÇDKNT konsantrasyonlarının yanı sıra, elektro eğirme parametrelerinin elektro eğirmeli ÇDKNT/TPU nanolif membranın morfolojisi, elektromekanik ve duyusal özellikleri üzerinde önemli bir etkisi vardır. Sonuçlar, daha düşük kollektör hızı ile uçtan kollektöre olan mesafenin ve daha yüksek elektro-eğirme süresinin, daha homojen bir şekilde dağılmış lifli yapıların oluşumuna yol açtığını ve bunun da iletkenliği ve gerinim duyarlılığını arttırdığını göstermektedir. Sonuç olarak, tekrarlanabilirlik testlerinden, tüm numuneler gerinim altında oldukça benzer doğrusal tepkiler göstermektedir, bu da yüksek düzeyde tekrarlanabilir bir imalat sürecine işaret etmektedir. Elde edilen sonuçlar, özellikle esnek gerinim sensörlerinin üretiminde elektro-eğirme parametrelerinin kontrolünün öneminin daha iyi anlaşılmasına yardımcı olabilmektedir.

Published: December 2024

Elektrokardiyografi (EKG), kalbin elektriksel aktivitesini izleyerek ritim ve fonksiyon bozukluklarını tespit etmekte kullanılan, invazif olmayan bir tanı yöntemidir. EKG sinyalleri genellikle düşük genlikli ve karmaşık yapıda olup, bu sinyallerdeki küçük değişiklikler gözle fark edilemeyebilir. Aritmiler, her zaman ciddi olmasa da, kalp hastalığı semptomlarına ve potansiyel olarak tehlikeli durumlara yol açabilir. Yapay zeka, EKG verilerini analiz ederek bu tür kalp hastalıklarının daha hızlı ve doğru bir şekilde tespit edilmesine olanak sağlar, böylece klinik kararların desteklenmesine katkıda bulunur. Bu çalışmada, PhysioNet/CinC Challenge 2016 veri seti kullanılarak, Chroma spektrogramları oluşturulmuş ve bu veriler üzerinde altı farklı önceden eğitilmiş ağ modeli test edilmiştir. Modeller, üç farklı doğrulama yöntemi ve altı farklı sınıflandırıcı ile değerlendirilmiştir. Sonuçlar, MobileNet V2 modeli ile Q-DVM sınıflandırıcısının en iyi performansı sergilediğini göstermiştir. Modelimiz, doğruluk (%87,6), duyarlılık (%96,1), kesinlik (%88,9) ve F1 skoru (%92,4) açısından güçlü ve iyi bir performans sergilemiştir.

The grammatical category of the case in the Ukrainian and Croatian languages is among the most important grammatical categories of a noun bearing in mind that it is consistently represented by the morphological means (the endings). The case is a regular type of the noun inflexion, which is divided into the biggest compared with the other morphological categories in the‑se languages morphological grammemes – seven cases – and is a consistently correlative morphological category of an absolute alternational type, characterized by closeness to the vocabulary influence. The case system is not expressed morphologically in Ukrainian and Croatian. In the grammatical structure of the Ukrainian and Croatian languages the vocative is usually represented by the morphological, syntactic and prosodic means. From the morphological point of view the vocative has in both languages in some cases an inflexional affix (the ending), indicating the syntactic bonds, semantic and syntactic relations of the form of the case to the other components of a sentence.We have explored the morphological and prosodic characteristics of the vocative and its semantic and syntactic variants in Ukrainian and Croatian. The vocative has its own distinguishing morphological features in the modern Ukrainian and Croatian languages. In both languages these are the ending and intonation. In the Croatian language, in contrast to the Ukrainian, the vocative is also characterized by the change of some other prosodic features. In particular, these are the changes of the qualitative and quantitative characteristics of the accent, the length appearance, etc. In some cases, when in both languages the vocative is morphologically identical with the nominative, the absence of the morphological features is compensated by such a prosodic feature as the intonation. The prospect of this research is to expand the investigated material to trace the vocative usage, to reveal its competitive potential, and peculiarities of its functioning in the texts of different genres on the materials of the different Slav languages.
ZWYCZAJE ESTÓW WEDŁUG RELACJI PODRÓŻNIKA WULFSTANA

Published: December 2024

The article presents the Old English version of Wulfstan’s voyage to the mouth of the Vistula, together with its translation into Polish. When browsing through the Polish literature devoted to this particular voyage, one can notice that the original Old English version of it, which served as the basis of translation into other languages including Polish, is lacking in it. Therefore this article is to serve as a complementation of the Polish literature by the original Old English version of Wulfstan’s voyage. This voyage most likely took place between 870 and 890 and it started in the Danish town of Hedeby and ended in Truso, an important settlement and port city on the Prussian lands lying towards the east of the estuary of the Vistula. Wulfstan mainly concentrates his attention on different ways of life and traditions of the people of Truso. The majority of attention is devoted to the festivities following the death of a person.

Writing the Croatian Tales of Long Ago, the authoress Ivana Brlić-Mažuranić incorporated an idea of maternity and family in the narrative text, which become a source of human existence. While the Croatian Tales of Long Ago have preoccupied the Croatian and the foreign critic audience, having been understood as the best collection of the Croatian artistic fairy tales, sub‑sequent to both editions, the 1943 and the 1993 one, the critic and historico-literary receptions are almost completely absented when it comes to the authoress’ fairy tales beyond the collection. Therefore, a position of family, which is a significant factor and an educational element in these authoress’ fairy tales as well, is being analyzed by virtue of a pedagogical perusal of Ivana Brlić-Mažuranić’s fairy tales published in the periodicals even posthumous to the authoress’ lifetime. A position of family as a special educational value, a motor of action, and a motivational stronghold in the observation of the fairy tale corpus, will be pinpointed by interpretation, detection method, and an analytical perusal.
TEXT EXPERIMENT, RADICALISM AND STYLISTIC ORIENTATIONS OF YOUNG SERBIAN PROSE IN STORIES FROM SAVA DAMJANOV'S GLOSOLALIJA
Authors:   Филозофски факултет у Новом Саду, НИКОЛИЋ Јована
Published: December 2024

Sava Damjanov is synonymous with radical changes in Serbian literature. In his works, by introducing new prose procedures and experimenting with the text, he liberated the language and showed that it had no boundaries. The present paper deals with six stories integrated under the joint title “Research of Perfection” from the collection “Glossolalia”. The aim of the paper is to familiarise readers with the poetics of Sava Damjanov, as well as with the text that resists each interpretation, because Damjanov is beyond any form. Numerous revolutionary experiments on text and language make the “Research of Perfection” an inexhaustible source of symbols.
MODELS OF LITERARY HISTORY, NARRATION AND IDENTITY
Authors:   Filozofski fakultet Sveučilišta u Osijeku, PETERNAI-ANDRIĆ Kristina
Published: December 2024

In this article, various approaches to the narrative in historiography are analysed and brought into connection with different models of literary history. The thesis that the narrative is constitutive for history, as well as for the construction of identity, is considered here through a survey of ideas proposed by H. White, P. Ricoeur, J. F. Lyotard, L. O. Mink on the one side, and D. Carr, J. Bruner and O. Sacks on the other. While the former view the narrative as a posterior product of the activity of a subject, the latter rather affirm that the narrative (i.e. stories) is inherent in human activities and in the course of life itself. Their common assumption of a necessary interrelatedness of the narrative and life is opposed by G. Strawson, who tries to disprove it by arguing against the idea that the experience of a past is inevitably constituted through narratives. Finally, Strawson’s distinction between ’diachronic‘ and ’episodic‘ subjects (individuals) is considered here in parallel with various models of literary history. Just as in the different models of self-perception proposed by G. Strawson, we deal with contrary ways of remembering past experiences and different approaches to selves, but cannot speak of a system of inferiority/ superiority, we similarly should not rank different models of literary history according to a hierarchy.
SEARCHING FOR OTHERNESS: IMAGES OF ORIENTAL WOMEN IN THE TRAVEL WRITINGS OF GERMAN WOMEN WRITERS

In the women’s travel literature, the topos of harem and the oriental wo‑men is one of the most important features of the imaginary Orient. The fantasies about prisoners who just wait to sexually satisfy their master are just some of the European ideas about the harem. Such a concept was the result of the Scheherazade’s stories and the fairy tales from One Thousand and One Nights that provoked European ideas about the harem among writers of that time. In the analysed travel books by German women writers: Ide Pfeiffer – Reise einer Wienerin in das Heilige Land, 1844, Ide von Hahn-Hahn – Orientalische Briefe 1844, Marie Schuber – Meine Pilgerreise über Rom, Griechenland und Egypten durch die Wüste nach Jerusalem und zurück vom 4. October 1847 bis 25. September 1848, 1850 and Louise Mühlbach – Reisebriefe aus Aegypten, 1871, a special focus was placed on the differences between the East and the West, in terms of producing binary oppositions, e.g. Westerners are white, advanced and capable, while Orientals are dark, unjust, bad, etc. Based on this, the paper shows how such oppositions have consistently prevented the path of heterogeneity and kept the division into „we“ and „them“. Such examples show in which ways the authors of the analysed texts used the experience with a foreign culture to criticize their own society, with particular reference to the position of women in society, their identity and role. Finally, the perception of oriental women, as well as the institution of the harem, standing in the centre of the perception of the Orient, have also been explored.
IN MEMORIAM: KRSTO PIŽURICA (1927–2017)
Authors:   Fakultet za crnogorski jezik i književnost – Cetinje, RADOMAN Aleksandar
Published: December 2024

In this paper, the author provides an overview of the contribution of Krsto Pižurica to the Montenegristics. Pižurica’s literary analysis is characterized by a kind of methodological eclecticism. In terms of scope, global concept, value judgments and the like, his studies undoubtedly belong to the history of literature, but at the micro level, in the analysis of particular phenomena of a literary-artistic text, evaluation and lucid observation, his papers are closer to literary criticism discourse. Generally speaking, Pižurica’s contribution to the establishment of modern literary Montenegristics is of utmost significance. There is no doubt that his role in the critical evaluation of Njegoš’s, and especially Lalić’s works is exceptional, but other segments of his work, such as persistent and diligent scientific dealing with Montenegrin poetical tradition, from Njegoš and Stefan Perović Cuca to modern poets should not be noted as well.
THE SELECTED WORKS BY NOVAK KILIBARDA
Authors:   Filološki fakultet – Nikšić, PAJOVIĆ-DUJOVIĆ Ljiljana
Published: December 2024

The Selected Works by Novak Kilibarda in four books (Podgorica: UDG, 2017) reflect his specific creator’s status – status of a connoisseur who is fascinated by the oral literature. The first two books represent his artistic, and the last two – his scientific oeuvre. They have been integrated through the fact that Kilibarda brought new life to the treasuries of folklore tradition, always at least in two ways: in terms of interpretation and in terms of literary reconstruction of folklore templates.
In this paper, the author points to Kilibarda’s authentic scientific reflections and methodological solutions he utilized to pave the way to cultural and political studies, nowadays very popular.

Authors:   Fakultet za crnogorski jezik i književnost – Cetinje, TERIĆ Marijana
Published: December 2024

In this paper, the author reflects on the importance of Crnogorske filološke studije (Montenegrin Philological Studies) by Milorad Nikčević. Given that Nikčević is one of the few intellectuals striving to strengthen Montenegrin-Croatian cultural links and promote a number of neglected values, the author reviews the texts included in this work, structured into three units. In doing so, the author enables the readers to follow inter-cultural relations between the two countries, the scientific and cultural engagement of numerous authors, as well as the immeasurable result of Nikčević's research work. In this context, it is concluded that Crnogorske filološke studije present a great contribution to science on literature, especially Montenegrin one.
THE ROLE OF SIMPLE FORMS IN ANDRIĆ’S NOVEL NA DRINI ĆUPRIJA
Authors:   Filozofski fakultet Osijek, VARGA-OSWALD Tina , BOŠNJAK Marijana
Published: December 2024

By analysing the novel Na Drini ćuprija (The Bridge on the Drina), created through the integration of the faction based on the scientific knowledge from Andrić’s doctoral dissertation and the fiction derived from the artistic achievements of his earlier short-stories whose characters were integrated into the novel, it becomes apparent that the further upgrading of the novel is based on the incorporation of simple forms. Unlike the myth that is implicit in the work and which makes a fictional world for itself, legend is explicit, and so is traditional story. However, the multicultural world of Bosnia and Herzegovina has produced variations of traditional stories with characters of different national and cultural backgrounds, so they often oppose one another and function as memorabilia. Additionally, Andrić’s narrator often contradicts traditional stories by the novel’s narrative, demystifying and stigmatising them as unbelievable for the world of the novel. Hence, simple forms function as the building stones from which the Višegrad’s bridge was built.
