- MakaleAçık Erişim2026Ahl al-Sunnat Textbooks Prepared for Primary Education in Iran in the Context of the Reflection of Ideological Discourse in the Curriculum
Demir, Habip
Purpose: This study aims to examine how the official ideological discourse in Iran is produced through the educational curriculum and how Sunni Islam is positioned within this institutional discourse. In this context, our study examines how Sunni Islam is represented in the Ma`& amacr;rif-i Isl & amacr;m & imacr;: V & imacr;je-yi Ahl al-Sunnat textbooks prepared for Sunni students at the primary education level in Iran, and through which discursive strategies this representation is constructed. Considering the determining influence of Twelver Shi'ism- the official sect of the Islamic Republic of Iran-on state institutions and the educational system, the way Sunnism is defined in institutional texts emerges as a significant subject of scholarly inquiry. In this context, the study seeks to demonstrate that sectarian identities are produced not only through doctrinal differences but also through institutional discourse and educational materials. The central research problem of the study is to identify the concepts, historical references, and narratives through which the Sunni sect is represented within Iran's official educational system. Method: The study was designed within the framework of a qualitative research approach. The data source for the study consists of the elective textbooks titled Ma`& amacr;rif-i Isl & amacr;m & imacr;: V & imacr;jeyi Ahl al-Sunnat prepared for Sunni students by the Iranian Ministry of Education as a supplement to the mandatory textbooks for elementary school (grades 2-6) and middle school (grades 7-9). A total of 8 textbooks were subjected to document analysis in this study; the books were examined holistically, and the texts, activities, and visual narratives were evaluated thematically using a discourse analysis approach. Findings: The findings reveal that Sunni identity in the examined textbooks is represented through several recurring thematic frameworks. In sections related to ritual practices, the practices of Sunni legal schools are explained in detail, enabling Sunni students to learn the religious practices associated with their own tradition. At the same time, the selection of historical figures largely avoids controversial personalities that could potentially generate sectarian tensions; instead, the textbooks highlight companions and scholars who are respected to some extent in both Sunni and Shi'i traditions. Furthermore, narratives concerning the Ahl al-Bayt and the event of Karbala are presented both as shared religious references and as significant elements of Shi'i historical discourse. The treatment of concepts such as taqlid, mujtahid, and religious leadership also indicates that these textbooks function not merely as pedagogical materials but as texts that carry ideological meanings associated with the political and ideological discourse of the Iranian state. Conclusion: The study concludes that the textbooks prepared for Sunni students in Iran constitute important institutional texts that demonstrate how sectarian identity is represented at the institutional level. Within these texts, Sunni identity is recognized and made visible to a certain extent; however, it is simultaneously redefined within a discursive framework compatible with the official Shi'i ideological structure. In this regard, the research contributes to the literature in the field of History of Islamic Sects by demonstrating how sectarian identities are produced and represented through educational materials. Moreover, the findings contribute to contemporary discussions on the relationship between sectarian identity and education, while also indicating new directions for future research on similar institutional texts.

Köse, Asli
Employing the systematic review methodology, this study aims to address how digital health literacy and e-health literacy influence people's quality of life. This systematic review includes studies that examined the effect of e-health literacy and digital health literacy on quality of life. The results of 12 research papers meeting the standards established within the parameters of this study were divided into two groups: ehealth literacy and digital health literacy. The effect of e-health literacy on quality of life was assessed in five of the thirteen studies, whereas that of digital health literacy on quality of life was assessed in eight of them. The study sample consisted of people with cancer, people with long-term conditions like asthma, people who were following their postoperative treatment regimens, people affected by the COVID-19 epidemic, the elderly, women, children, and students. Only one study reported that e-health literacy had a negative influence on quality of life, whereas 11 studies emphasized that digital health and e-health literacy had a positive influence. Policies are required to facilitate the use and access to digital health technology by various societal groups, including patients, the elderly, women with unequal social status, children, and learners.
- MakaleAçık Erişim2026Formulation of mechanical properties of hybrid fiber alkali-activated concretes by data analysis
Aksut, Yavuz Selim; Yetgín, Sukru
In this study, ground blast furnace slag (GBFS) and waste volcanic rock dust (RD) produced in a natural stone processing plant were used as binders. The binders were activated with Sodium Hydroxide (NaOH) and Sodium Silicate (Na2SiO3) to produce two types of concrete: alkali-activated concrete without fibers (AAC) and alkali-activated concrete with fibers (FAAC). In the production of concrete, steel and polyester fibers were used separately and hybrid at 0.25%, 0.50%, 0.75% and 1.0% by volume and a total of 117 15x15x15 cm cube specimens were produced. The mechanical properties of the specimens were evaluated by concrete surface hardness, ultrasonic pulse velocity and concrete compressive strength tests at 3, 7 and 28 days. The results obtained using non-destructive test methods were matched with concrete compressive strength values using various empirical formulas. Calculated concrete compressive strength values and actual concrete compressive strength values were compared using data analysis method. As a result, it was observed that there was a very significant correlation between the experimental compressive strength and the combined method in which 7-day surface hardness and ultrasound transmission rate were used together to calculate the compressive strength.

- MakaleAçık Erişim2026A Land Use Analysis of Coastal Reclamation Areas in Ortahisar District, Trabzon (2000-2024)
Üzülmez, Mehmet
This study evaluates land use patterns in reclaimed coastal areas of Ortahisar district, Trabzon, from 2000 to 2024. It examines the role, functions, and environmental and structural impacts of reclamation in urban development. In mountainous cities like Trabzon, with limited flat land, sea filling is a key urban expansion strategy. The research combines literature review, satellite image analysis, and GIS mapping (ArcGIS), supported by climate, population, and topographic data from official sources. The study analyses reclaimed zones including Akyaz & imath;, Be & scedil;irli, Ganita, and De & gbreve;irmendere. InAkyaz & imath;, 39 hectares serve the & Scedil;enol G & uuml;ne & scedil;Sports Complex, and 29 hectares serve the city hospital ,which is currently under construction, alongside a mosque, fishermen's shelter, and parking. Ganita includes 17 hectares of parks and recreation and 9 hectares for transport infrastructure, reflecting a public-use planning approach. De & gbreve;irmendere hosts parks, fishermen's shelters, roads, a port, and breakwaters, with about 28 hectares unused. These areas address population growth and land scarcity, creating new urban spaces but posing environmental and engineering risks. International studies highlight issues such as ground settlement, structural instability, flood and storm vulnerability, and marine ecosystem damage in reclaimed lands. While valuable for infrastructure and public services, reclamation should be managed beyond spatial growth. The study stresses how multifunctional, public-focused, strategic planning shaped these areas. However, comprehensive interdisciplinary approaches are needed for ground safety, sustainability, and ecosystem protection. Future planning must mandate geotechnical surveys and environmental impact assessments. Reclamation should align with natural processes, not just physical expansion. Public participation and integrating local needs are crucial. Transport and access plans should balance coastal access and sustainability. Ortahisar's reclamations offer short-term urban solutions, but long-term risk reduction requires integrated sustainable planning.
- MakaleAçık Erişim2026The mediating role of physical self-perception and the moderating effect of gender in the association between physical activity and psychological well-being among young recreational participants
Ekizoglu, Ozlem; Tetik, Sibel; Zambak, Omer; Temur, Canan Sayin; Can, Yusuf; Isik, Utku; Koc, Mustafa Can
Background/objective Psychological well-being disorders are increasingly prevalent among young people. While physical activity is known to benefit psychological well-being, the mechanisms-particularly the role of physical self-perception and gender in recreational context remain underexplored. Grounded in the Conservation of Resources (COR) Theory, this study investigates the mediating role of physical self-perception in the relationship between recreational physical activity and psychological well-being and examines whether gender moderates this mediation among youth aged 15-24.Methods A descriptive-relational survey design was employed. The sample comprised 468 young adults (58.5% male, 41.5% female; M_age = 20.08) who regularly participated in recreational physical activities. Data were collected using the International Physical Activity Questionnaire-Short Form (IPAQ-SF), the Physical Self-Perception Profile (PSPP), and the Warwick-Edinburgh Mental Well-being Scale (WEMWBS). Mediation and moderation analyses were conducted using PROCESS macro-Models 4 and 7.Results The direct effect of physical activity on psychological well-being was not significant. However, physical self-perception fully mediated the relationship between physical activity and psychological well-being (indirect effect: beta = 0.219, 95% CI [0.151, 0.290]). Among the sub-dimensions of physical self-perception, body attractiveness had the strongest mediating effect. Moderation analysis revealed that gender did not significantly moderate the mediation pathways (a path: p = 0.156; b path: p = 0.954). The mediation mechanism operated with similar strength in both males and females.Conclusion Recreational physical activity improves psychological well-being entirely through the enhancement of physical self-perception, supporting the COR theory that physical activity acts as a resource investment. This mechanism is universal across genders in recreational settings. Interventions aiming to improve youth psychological well-being should not only promote physical activity but specifically focus on fostering positive physical self-perception and body image in inclusive, non-judgmental environments.
- MakaleAçık Erişim2026The COPD-augmented R2CHA2DS2-VA score: development and internal assessment for predicting one-year outcomes after transcatheter aortic valve implantation
Boyaci, Faruk; Sahin, Mustafa Kursat; Akcay, Murat; Yanik, Ahmet; Yenercag, Mustafa; Seker, Onur Osman; Ucar, Melisa; Kokcu, Halil Ibrahim; Ozturk, Berkant; Kaya, Enes
Background Existing CHA(2)DS(2)-VASc-based scores incompletely capture the prognostic impact of chronic obstructive pulmonary disease (COPD) and of graded renal dysfunction in patients undergoing transcatheter aortic valve implantation (TAVI). We acknowledge that the score's development in a high-risk, high-comorbidity cohort may produce optimistic performance estimates that require attenuation through external validation. We aimed to develop a novel COPD-augmented R(2)CHA(2)DS(2)-VA (COPD-R(2)CHA(2)DS(2)-VA) score that systematically integrates quantitative renal function and COPD, and to internally assess its discriminative performance for one-year all-cause mortality and major adverse cardiovascular events (MACE). Methods In this single-center, retrospective cohort study, 622 consecutive patients undergoing TAVI for severe aortic stenosis (2018-2024) were analyzed. The COPD-R(2)CHA(2)DS(2)-VA score was constructed as a prespecified clinical tool by augmenting the R(2)CHA(2)DS(2)-VA framework with COPD (1 point) and refining renal dysfunction into two graded estimated glomerular filtration rate strata (eGFR 30-59 mL/min/1.73 m & sup2;: 1 point; eGFR < 30: 2 points). Discriminative performance was evaluated using receiver operating characteristic curve analysis with bootstrap internal validation (2,000 resamples) and compared with established CHA(2)DS(2)-VASc-based scores. Multivariable logistic regression assessed the independent prognostic value of the score treated as a continuous variable. Results The COPD-R(2)CHA(2)DS(2)-VA score demonstrated encouraging discriminative ability for one-year all-cause mortality (apparent area under the curve [AUC] 0.946, 95% CI 0.926-0.971). As a prespecified tool with fixed component weights, bootstrap internal validation confirmed negligible optimism (mean optimism - 0.00014), with bias-corrected AUC identical to the apparent value. The addition of COPD significantly improved mortality discrimination over the R(2)CHA(2)DS(2)-VA score (Delta AUC + 0.033, p = 0.0001). For one-year MACE, the apparent AUC was 0.806 (95% CI 0.765-0.852); the addition of COPD did not significantly enhance MACE discrimination (Delta AUC + 0.001, p = 0.853). In multivariable analysis, each one-point increase in the COPD-R(2)CHA(2)DS(2)-VA score was independently associated with 3.52-fold higher odds of one-year mortality (95% CI 2.45-5.06, p < 0.001) and 2.02-fold higher odds of MACE (95% CI 1.67-2.46, p < 0.001). The bias-corrected AUC of the full multivariable model was 0.973 (95% CI 0.962-0.984) for mortality and 0.795 (95% CI 0.752-0.841) for MACE. Conclusions The COPD-R(2)CHA(2)DS(2)-VA score demonstrated encouraging discriminative ability for one-year all-cause mortality after TAVI in this single-center development cohort (apparent AUC 0.946). However, this high discriminative performance is likely influenced by the elevated comorbidity burden in our cohort and the single-center design, and should be interpreted as an upper-bound estimate. The addition of COPD provides a statistically significant but clinically modest incremental improvement for mortality (Delta AUC + 0.033, p = 0.0001), with no significant enhancement for MACE (Delta AUC + 0.001, p = 0.853). These findings are preliminary and hypothesis-generating; urgent external validation in diverse, prospective cohorts is essential before any clinical application can be considered. At present, this score should be regarded as a development-phase, hypothesis-generating tool that complements rather than replaces guideline-recommended instruments such as STS-PROM and EuroSCORE II. The score's clinical utility remains unproven.
- MakaleAçık Erişim2026Mercury Removal from Glycine Leach Solutions Using Sodium Sulfide (Na2S) Precipitation
Kantarci, Sadiye; Alp, Ibrahim; Youpoungam, Abdou Azizi; Sivircik, Salih
Amino acid leaching has been considered an environmentally friendly alternative for gold recovery; however, the dissolution of mercury (Hg) during the leaching of amalgamation tailings remains a major challenge. This study is a novelty study that focuses on Hg removal by passing the Hg-containing tailings, previously processed by amalgamation, into solution via glycine (NH(2)CH2COOH) leaching. In this regard, a precipitation method using sodium sulfide (Na2S) was developed to remove Hg from solutions obtained after glycine leaching. The effects of precipitation time, pH, Na2S dosage, and temperature were investigated. The effects of pH, precipitation time, and temperature were found to be limited within the investigated ranges. The results showed that Na2S dosage was the most effective parameter in mercury removal. The initial Hg concentration of 12,160 ppb was reduced to 223 ppb at a Na2S:Hg molar ratio of 60, corresponding to approximately 98% removal efficiency under the selected operating conditions. Increasing the Na2S:Hg ratio to 80 resulted in a slightly higher removal efficiency (similar to 99%) with a final Hg concentration of 144 ppb; however, a ratio of 60 was considered optimal in terms of reagent consumption and process efficiency. The outcomes indicate that Hg removal with Na2S is a rapid and effective process under alkaline conditions, while Au remains in solution and Cu and Ag are partially removed, indicating limited selectivity and the need for further optimization. Therefore, this study provides a basis for developing more environmentally friendly processes for amalgamation tailings.

Oguz, Enes Cengiz; Gyasi, Evans Akwasi; Pala, Fahrettin; Pilatin, Abdulmuttalip; Barut, Abdulkadir
The study sheds light on the subtle interactions among financial development, foreign direct investment (FDI), and the quality of regulatory frameworks, with particular reference to their deep influence on renewable energy use and carbon emissions across 22 developed countries from 2002-2021. The results show an interesting tendency: Financial development and FDI will reduce reliance on renewable energy, whereas a significant increase in GDP per capita will increase reliance. Secondly, carbon emissions have a negative association with the adoption of renewable energy and financial development, though both reduce environmental quality; there is a positive relation between real gross domestic product (GDP) and energy depletion in terms of these toxic emissions. The significant role of regulatory quality as a moderator in this process is particularly striking. There is a direct correlation between financial stability and more robust regulation, resulting in reduced financial liquidity available for investing in renewable projects and restricting the free flow of clean FDI. Crucially, the paper argues that when combined with strong regulation, FDI is more likely to contribute to reductions in emissions, while FYGD, nevertheless regulated at a high level of quality, should raise emissions. Winding up, the result indicates that neither financial depth nor institutional quality, in isolation, is sufficient to deliver significant environmental improvement. Thus, it is urgent to adopt sound green finance policies and to formulate focused regulatory systems that integrate financial development and foreign direct investment with a broader sustainability agenda.
- Derleme MakaleAçık Erişim2026Nanoplastic Translocation Across Biological Barriers (Blood-Brain, Placental, Intestinal): Transport Mechanisms, Tissue-Specific Vulnerabilities, and a Corona-Driven Barrier Selectivity Framework
Berber, Ahmet Ali; Yildiz, Esra; Berber, Nurcan; Kurnaz, Muammer; Kenanoglu, Nihan Akinci
Nanoplastics (NPs; <= 1 & micro;m) have been detected in human placenta, blood, lung, atherosclerotic plaque, testis, semen, olfactory bulb, and brain, shifting the field from environmental description toward mechanistic interrogation of barrier crossing. This review synthesises current evidence on NP translocation across the intestinal epithelium, the blood-brain barrier (BBB) and the placental syncytiotrophoblast. We distinguish four evidence categories throughout the review: detection, association, mechanism, and causality. We also apply model-system labels (in silico, in vitro, ex vivo, animal, and human) to every mechanistic claim, so that the strength of each statement can be read off directly. Most current studies use pristine polystyrene nanoplastics at concentrations 3-6 orders of magnitude above plausible human exposure, so the mechanistic conclusions below are hypothesis-generating for human disease rather than definitive. We propose a working conceptual framework-corona-driven barrier selectivity (CDBS)-in which the particle-corona-surface complex, rather than the bare polymer, is hypothesised to dictate which receptor and transport machinery (TfR1, LRP1, FcRn, P-gp/BCRP, caveolae) each barrier engages. CDBS is offered as a hypothesis-stage organising tool requiring experimental validation, not as an established mechanism. We outline reported transport modes, including clathrin- and caveolin-mediated endocytosis, paracellular leakage via ROS-induced tight-junction disassembly, receptor-mediated transcytosis, and the candidate olfactory route. We emphasise that pristine polystyrene-bead doses commonly exceed plausible human exposure by 3-6 orders of magnitude, that detection methods underestimate sub-micrometre particles, and that causal links between NPs and human disease remain hypothesis-generating. A research agenda built on weathered reference materials, microphysiological systems, and integrative human biomarker science is proposed.

Berber, Ahmet Ali; Akbulut, Cansu; Demir, Sefika Nur; Kurnaz, Muammer
Microplastic (MP) contamination has become a defining feature of twenty-first century environmental change, yet the toxicological and ecological consequences for amphibians and reptiles-two vertebrate classes already facing severe extinction pressures-remain fragmented across taxa, regions, and methodological traditions. Here, we synthesize field and experimental evidence from five continents to provide a taxonomically balanced, mechanistically grounded, and geographically explicit assessment of MP exposure, bioaccumulation, and toxicity in herpetofauna, drawing on a structured literature search in Web of Science, Scopus, and PubMed (January 2015-March 2026). Field detection rates of MPs in amphibian larvae range from 26% in conservatively screened Central European populations to 73-80% in anuran tadpoles from high-anthropogenic-pressure Anatolian catchments, with fibrous polyethylene terephthalate (PET), polyethylene (PE), and polypropylene (PP) particles dominating the detected burden. Mechanistic evidence converges on oxidative stress cascades, hypothalamic-pituitary-thyroid axis disruption, gut and cutaneous microbiome dysbiosis, and compromised antiviral and antifungal immunity, with the latter potentially amplifying vulnerability to Batrachochytrium dendrobatidis and to ranavirus. Among reptiles, sea turtles display near-universal MP ingestion with documented maternal transfer to eggs; freshwater turtles, terrestrial squamates, and crocodilians remain critically understudied. Three structural asymmetries constrain current ecotoxicological risk characterization: taxonomic bias toward anurans and sea turtles, geographic bias toward the Global North, and experimental bias toward acute, supra-environmental laboratory exposures using pristine, single-polymer particles that fail to capture the chemical complexity of weathered field mixtures. We argue that MP burden may warrant consideration as a candidate stressor criterion within IUCN Red List assessments and within environmental risk assessment frameworks for freshwater and terrestrial biodiversity once a robust quantitative relationship between MP burden and demographic decline or population-level fitness has been established, and propose six hypothesis-driven research priorities: methodological standardization, reptile toxicokinetics, transgenerational epigenetics, MP-pathogen microbiome interactions and their translation into population viability models, temperature & times; MP interaction under climate warming, and population-genetic consequences of contemporary MP-driven selection, as the most tractable avenues for ecotoxicological progress and for the development of herpetofauna-specific risk characterization frameworks.

Objective: Coronary artery ectasia (CAE) is increasingly recognized as an active inflammatory vascular disorder rather than a benign anatomical variant. The pan-immune-inflammation value (PIV) is a novel biomarker integrating neutrophil, monocyte, platelet, and lymphocyte counts, providing a comprehensive measure of systemic inflammation. This study aimed to evaluate the association between PIV and CAE and to compare their diagnostic performance with that of conventional inflammatory indices. Method: In this retrospective case-control study, 17,538 patients who underwent elective coronary angiography between 2018 and 2024 were screened. A total of 228 patients with isolated CAE and 296 age-, sex-, and Body Mass Index (BMI)-matched controls with normal coronary arteries were included. Hematologic and biochemical parameters were analyzed, and inflammatory indices were calculated. Logistic regression and receiver operating characteristic (ROC) analyses were performed to identify independent predictors and assess diagnostic performance. Results: Patients with CAE had significantly higher PIV levels compared to controls (801.6 [504.4-1301.8] vs. 491.8 [302.4-872.7], P < 0.001). In multivariable logistic regression, log-transformed PIV remained independently associated with CAE (odds ratio [OR]: 1.987, 95% confidence interval [CI]: 1.057-3.737, P = 0.033), along with hypertension, triglycerides, high-density lipoprotein (HDL) cholesterol, and serum creatinine. PIV demonstrated the highest discriminative ability among all inflammatory indices (area under the curve [AUC]: 0.674, 95% CI: 0.623-0.722), and correlated strongly with the Systemic Immune-Inflammation Index (SII), neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and Systemic Inflammation Response Index (SIRI) (P = 0.75-0.94). Conclusion: Elevated PIV levels are independently associated with CAE, reflecting the pivotal role of systemic inflammation in its pathogenesis. Given its simplicity and availability, PIV may serve as a practical adjunctive marker for identifying patients at risk of CAE, warranting validation in larger prospective studies.

- MakaleAçık Erişim2026Determinants of healthy orthorexia and orthorexia nervosa: the roles of food security, dietary behaviors, and obesogenic environment
Koçak, Tevfik; Arpa Zemzemoglu, Tuba Eda; Türkkan, Tugba; Bülbül, Kenan; Yilmaz, Birsen
Orthorexia has recently gained attention as a two-dimensional construct centered on a shared health orientation. Recent conceptual developments distinguish healthy orthorexia (HeOr), defined as a non-pathological interest in healthy eating, from orthorexia nervosa (OrNe), characterized by rigid and compulsive food control accompanied by psychological and social impairment. This cross-sectional study investigated the associations of HeOr and OrNe with sociodemographic variables, dietary behaviors, and obesogenic environmental factors, and aimed to identify shared and distinct determinants of these tendencies with 1,015 adults aged 18-65 years. Orthorexia tendencies were assessed using the Teruel Orthorexia Scale. Additional measures included the Sustainable and Healthy Eating Behaviors Scale, Short Screening Questionnaire of Highly Processed Food Consumption, Adult Food Security Survey Module, Food Label Reading Attitude Scale, Food Choice Questionnaire, and the Obesogenic Environment Assessment Scale. In the adjusted regression models, HeOr was positively associated with sustainable and healthy eating behaviors (beta = 0.26), AFSS food-insecurity severity score (beta = 0.11), food label reading attitudes (beta = 0.07), health-related food choice motives (beta = 0.09), natural-ingredient preference (beta = 0.14), weight-control motives (beta = 0.15), ethical food choice motives (beta = 0.10), and obesogenic social determinants and effects (beta = 0.09). Conversely, affordability-related motives (beta = -0.08), emotional appeal (beta = -0.15), familiarity (beta = -0.10), and obesogenic cultural determinants/access to experts (beta = -0.12) were negatively associated with HeOr. For OrNe, positive associations were observed with sustainable and healthy eating behaviors (beta = 0.13), AFSS food-insecurity severity score (beta = 0.17), mood-related food choice motives (beta = 0.13), weight-control motives (beta = 0.26), familiarity (beta = 0.09), ethical food choice motives (beta = 0.18), and obesogenic social determinants and effects (beta = 0.30), whereas health-related food choice motives (beta = -0.12), affordability-related motives (beta = -0.08), and emotional appeal (beta = -0.24) showed negative associations. These findings suggest that orthorectic tendencies are associated with individual health motivations as well as broader behavioral and environmental contexts; however, because of the cross-sectional design, these associations should be interpreted as correlational and hypothesis-generating rather than causal.

Akbay, Yunus Emre; Evmes, Adem; Akyüz, Turgut
The subject of this article is to examine and analyze the understanding of propositions held by Ibn Kamm & umacr;na, who lived in the 13th century, from the perspective of the discipline of logic. Ibn Kamm & umacr;na is a profound thinker who left significant works in the fields of philosophy and logic by thoroughly examining the works of figures such as Ibn Maym & umacr;n, Ibn Sin & amacr;, al-Ghaz & amacr;li, Ab & umacr; al-Barak & amacr;t al-Baghd & amacr;di, Fakhr al-Din al-R & amacr;zi, and al-Suhrawardi. The primary aim of the article is to analyze in detail the manner in which Ibn Kamm & umacr;na approaches propositions, drawing upon the works he authored on matters of logic. The scope of the article is confined to al-Jad & imacr;d f & imacr;'l-hikma, Sharh al-us & umacr;l wa'l-jumal, and Sharh at-talw & imacr;h & amacr;t, which are among Ibn Kamm & umacr;na's works containing data on the subject of propositions, and within the context of these works, the definition of the proposition, categorical propositions, conditional propositions, modal propositions, the contradiction and conversion of propositions are comprehensively addressed. The literature review conducted revealed that the philosopher has been examined to a considerably limited extent in our country from the standpoint of logic, and this study is considered to make a significant contribution to remedying the aforementioned deficiency. A qualitative research methodology was adopted in the article, and techniques of analysis and comparison were employed. It is known that Ibn Kamm & umacr;na, unlike authors such as Aristotle, al-F & amacr;r & amacr;bi, and Ibn Sin & amacr;, did not compose an independent work on propositions. For this reason, approximately sixteen works that have survived to the present day were meticulously examined through an individual scanning method, passages related to the subject of propositions within the context of the three identified works were recorded, and the data obtained were systematically classified and analyzed. As a result, it has been demonstrated that Ibn Kamm & umacr;na's treatment of propositions draws substantially from the Peripatetic tradition through Ibn Sin & amacr;. Ibn Kamm & umacr;na shares a common view with Ibn Sin & amacr; on the matter of indefinite propositions and explicitly states that such propositions ought to be understood as particular. Furthermore, he addresses propositions holistically on the subject of modality without making a distinction between simple and composite; and emphasizes that there is no limitation with respect to the number of modal propositions and

Alkan, Asli; Anaç, Halil
In this study, an enhanced semianalytical framework is developed for solving nonlinear fractional differential equations involving the Caputo-Fabrizio fractional operator. The proposed Caputo-Fabrizio q-Kushare homotopy analysis transform method (CFq-KHATM) combines the Caputo-Fabrizio derivative, Kushare transform, and q-homotopy analysis within a unified operator-consistent framework. Unlike conventional hybrid approaches, the method preserves the nonsingular exponential memory structure of the Caputo-Fabrizio derivative and provides additional convergence-control flexibility through the auxiliary parameter & hbar; and q-deformation parameter n. To demonstrate its applicability, a Caputo-Fabrizio fractional epidemic model with memory-dependent transmission dynamics is investigated. Numerical simulations for different fractional-order values show that memory effects significantly influence epidemic evolution, infection persistence, and environmental viral dynamics. Furthermore, comparisons with existing methods together with absolute and relative error analyses confirm the accuracy, stability, and convergence efficiency of the proposed framework. The obtained results indicate that CFq-KHATM is a flexible and computationally reliable tool for nonlinear fractional epidemic systems and other memory-dependent dynamical models.
- MakaleAçık Erişim2026Comparison of Radiologic and Clinical Results of Short-Long Level Posterior Fusion in Lenke Type 5C Scoliosis
Tas, Suleyman K.; Aydin, Abdurrahman; Yetkin, Cem; Albayrak, Akif; Kaygusuz, Mehmet A.
Background: Lenke type 5C scoliosis is treated surgically with long-segment (nonselective) or short-segment (selective) level fusion. For Lenke type 5C scoliosis, no standardized criteria exist for selecting proximal and distal fusion levels. Studies report that short-segment level fusion patients with correct patient selection have a direct effect on the result of a well-balanced spine. Purpose: To compare the midterm and long-term radiologic and clinical outcomes of short-segment (selective) vs long-segment (nonselective) fusion in Lenke type 5C scoliosis. Design: Retrospective cohort study. Patient sample: This retrospective study evaluated patients who underwent posterior instrumentation for Lenke type 5C adolescent idiopathic scoliosis (AIS) at our institution between 2005 and 2016. Outcome measure: Physiologic measures: radiological evaluations included coronal, sagittal, and spinopelvic balance assessments as well as shoulder balance parameters on X-ray. Functional measures: clinical evaluations were performed using the SF-36 and SRS-22(r) scores. Methods: Patients with Lenke type 5C scoliosis who underwent selective (group 1) or nonselective (group 2) instrumentation were retrospectively analyzed. Group 1 included 47 patients (42 females and five males) with a mean age of 16.1 +/- 2.4 year (range, 12-22), and group 2 included 58 patients (53 females and five males) with a mean age of 16.3 +/- 3.4 yr (range, 12-24; P > .05). Radiological evaluations included coronal, sagittal, and spinopelvic balance assessments, as well as shoulder balance parameters. Clinical evaluations were performed using SF-36 and SRS-22(r) scores; results were compared between the two groups. Results: Both groups exhibited similar results in terms of coronal, sagittal, and spinopelvic balance as well as shoulder balance in many data after surgery (P > .05). Clinical outcomes, assessed via SF-36 mental health and SRS-22(r) scores, did not show statistically significant differences between groups (P > .05), except fort the physical role difficulty domain of the SF-36, where the selective fusion group (77.1 +/- 31.6) showed significantly better scores than nonselective group (58.2 +/- 36.1). However, the mean surgical time and transfusion requirement were significantly lower in the selective fusion group. Conclusion: When appropriately applied, selective fusion achieves comparable radiologic and clinical outcomes to nonselective fusion, with the added advantages of shorter surgical time and lower transfusion requirements.

Tepe, Dilsat; Ulusahin, Mehmet; Kula, Sibel; Yilmaz, Gurdal
Objective: Granulomatous mastitis (GM) is a chronic inflammatory breast disease with a heterogeneous clinical presentation and uncertain optimal management. Increasing evidence suggests a role for Corynebacterium species, particularly Corynebacterium kroppenstedtii, in its pathogenesis. This study aimed to evaluate the clinical characteristics, treatment strategies, and outcomes of granulomatous mastitis, with particular emphasis on cases associated with Corynebacterium species and the impact of antibiotic therapy. Materials and Methods: This retrospective cohort study included female patients with GM treated at a university hospital between January 2018 and January 2023. Patients were grouped according to Corynebacterium isolation. Clinical characteristics, microbiological findings, and treatment modalities-oral steroids, combined antibiotic-steroid therapy, antibiotics with intralesional steroids, and segmental mastectomy-were evaluated. The impact of lipophilic antibiotics (tetracyclines, linezolid, rifampin) combined with steroids was assessed. Recurrence rates and associated factors, including symptom duration, were analyzed. Results: A total of 165 patients were included in the study, of whom 25 tested positive and 140 negative. Corynebacterium spp. were detected in 15.15% of cases, with C. kroppenstedtii identified in 8.48%. Patients with Corynebacterium-associated GM had more extensive abscess formation and required more interventional procedures. Multimodal treatment strategies combining steroids, antibiotics, and surgery resulted in favorable outcomes. Lipophilic antibiotics combined with steroids showed a positive but statistically non-significant effect. Recurrence occurred in 16.4% of patients and was associated with longer symptom duration. Conclusion: Accurate microbiological identification is essential in GM, particularly in C. kroppenstedtii infections, to guide targeted antibiotic therapy and reduce recurrence. Tailored management strategies, including lipophilic antibiotics, may improve outcomes. Further studies are needed to define optimal treatment duration and the role of surgery in refrac-GM.

Background and Study Aim Ergogenic aids are widely used to enhance exercise performance and training adaptations. Among these, caffeine is recognized for its stimulatory effects on the central nervous system and neuromuscular function. Despite their widespread use, the relative effectiveness of such aids in improving performance in precision-based target sports such as archery remains a matter of practical interest. This study aimed to examine the effects of acute caffeine supplementation on shooting performance in university-level archers. Material and Methods A total of 12 licensed university archers (mean age: 22.92 +/- 2.11 years) participated in this study. A single-group pretest-posttest experimental design was employed. Participants completed two laboratory sessions separated by 72 hours under standardized conditions. In each session, anthropometric and hearing assessments were conducted. This was followed by the ingestion of 200 mg of caffeine. After a 60-minute absorption period, archers performed shooting tests at 18 meters. The protocol included practice trials and 10 sets of scoring shots. Data were analyzed using paired-samples t-tests and repeated-measures ANOVA. These methods accounted for within-subject variability across sets. Statistical significance was set at p < .05. Results Posttest scores were consistently higher than pretest scores across most sets. Statistically significant improvements were observed in Sets 2, 3, 4, 6, 8, 9, and 10 (p < .05). Sets 1, 5, and 7 showed nonsignificant differences. Overall performance increased significantly from 6.61 +/- 1.20 to 8.33 +/- 0.39 (p < .001), with a large effect size (Cohen's d = 1.90; eta 2 = .50). Repeated-measures ANOVA revealed a significant main effect of condition (p < .001). No significant set or interaction effects were found. This indicates that performance improvements were consistent across shooting sets. Conclusions Acute caffeine supplementation was associated with improved shooting performance in university-level archers. The findings suggest that caffeine may have potential as an ergogenic aid in precision-oriented sports requiring sustained attention and performance consistency. However, the results should be interpreted with caution due to methodological limitations. These include the absence of a control condition and the small sample size. Further randomized placebo-controlled studies are needed to confirm and extend these findings.
