Özellikleri ve Metodu Açısından Kemâhî’nin Müsned Şerhi Tenvîrü’s-Sened fî Îdâhi Rumûzi’l-Müsned’i
Get PDFHadis tarihine bakıldığında hadis şerhleri önemli bir yere sahiptir. Hadis şerh faaliyetleri, hadislerde bulunan garip kelimelerin tercümeleri ve zahiren çelişkili gibi görülen hadislerin açıklamaları niteliğinde başlamıştır. Hicrî dördüncü asırda Ebû Süleyman Hamd b. Muhammed el-Hattabî’nin (ö. 388/998), Ebû Dâvûd’un (ö. 275/889) es-Sünen’i üzerine yazdığı Meâlimü’s-sünen eseriyle birlikte sistematik bir hal alan şerh faaliyetleri günümüze kadar devam edegelmiştir. Osmanlı hadis kültürü, 623 yıl boyunca hadis şerh faaliyetlerinin merkezinde yer almıştır. Makalemize konu olan Osman b. Yakup el-Kemâhî, XVIII. yüzyılda yaşamış Osmanlı muhaddislerindendir ve iki hadis şerhi kaleme almıştır. Bu araştırmada, İmam A’zam’a (ö. 150/767) ve Müsned’ine yoğunlaşmak yerine Kemâhî’nin Müsned üzerine yazdığı Tenvîrü’s-sened adlı şerh kitabı ele alınacaktır. Bu şerh kitabı, metninin (Müsned) te’lif olarak ilk asra yakın olması itibâriyle önemli hadis şerhleri arasında değerlendirilebilir. Bunun yanı sıra kaynak zenginliği ve farklı ilim dallarını ihtivâ eden şerhleriyle çok yönlü ve özgün bir şerhtir. 221 varaklık Tunus nüshasının incelenmesi sonucunda tespit edilen Tenvîr şerhinin önemi, özellikleri ve Kemâhî’nin bu eserdeki şerh metodu ele alınacaktır
Assessment of the involvement of the inferior glenohumeral capsuloligamentous complex in frozen shoulder using shear wave elastography: a study with MRI correlation
Get PDFObjectives This study aimed to evaluate the efficacy of shear wave elastography (SWE) as a diagnostic tool for frozen shoulder (FS). Methods Thirty patients with FS and 34 healthy volunteers were included in the study. Patients with clinical findings consistent with FS and whose MRI results were indicative of FS were included. SWE was performed on these patients, measuring stiffness in the anterior band of the inferior glenohumeral capsuloligamentous complex (IGHCC) using the Virtual Touch Quantification elastography method. Stiffness values were expressed as shear wave velocity (SWV) in meters per second, and statistical analyses were performed to compare stiffness values between the FS and control groups. Results Significant differences in SWV values were observed between the FS and the control groups (P < .001). Additionally, a significant interaction between group and gender was observed (P = .007) based on a 2-way analysis of variance. Conclusion SWE revealed significant stiffening of the IGHCC in FS patients compared to controls, demonstrating its practicality and reliability as an imaging method alongside MRI for assessing IGHCC involvement in FS patients. Advances in knowledge SWE may serve as an alternative imaging method for diagnosing and monitoring FS
Cost Analysis of COPD: A Case Study in Düzce University Hospital
Get PDFObjective: The aim of the study is to analyze the costs of Chronic Obstructive Pulmonary Disease (COPD) from the perspective of the Social Security Institution (SSI). Method: In the research, data obtained retrospectively using the qualitative method were subjected to document analysis. The study covers 241 COPD patients in 2022 in the Chest Diseases unit of D & uuml;zce University Health Application and Research Center/Hospital. No sample was selected in the research, but the entire population was used. Data were subjected to multivariate regression analysis. Costs include examinations, medical supplies, medications, imaging and laboratory tests. Results: Of 130 outpatients, 110 (85%) were male, 20 (15%) were female, the mean age was 66.82 years, and outpatient treatment cost was 127.76h (140.16)/patient. Of this, 1,059.97 h (16.17) for medical supplies, 907.74 h (30.21) for investigations. It was determined that the gender, age, and hospitalization duration of the patients changed the treatment costs (p<0.05). In addition, it was determined that the SSI incurred an average annual drug cost of 6,321.84 h (554.98) /patient was determined. Conclusions: The study found that treating COPD is a significant economic burden per patient for the SSI. A significant portion of this cost is comprised of medication expenses. This increases the lifetime costs of COPD. In order to reduce the cost of the disease, both necessary measures should beAtaken to reduce the risk of developing the disease, and lower-cost methods should be followed in the treatment of the disease
Sovereignty of Instrumentality Examination of Digital Publishing From the Lens of Psychopolitics
Get PDFThis study posits that a multidisciplinary approach is necessary to comprehensively analyze digital broadcasting environments, encompassing technical, cultural, psychological, and political dimensions. The research examines how digital broadcasting transforms the individual's identity, structures of desire, and mechanisms of consent, drawing on the ideas of theorists such as Adorno, Marcuse, Feenberg, and Rouvroy, especially within the framework of the concept of instrumental reason. The pervasive use of algorithms to manipulate content on digital platforms has the potential to subject the individual to unseen and covert forms of influence, thereby altering the very dynamics of personal identity, desire, and consent. In this context, the concepts of algorithmic governmentality, cultural hegemony, and surveillance capitalism are employed to demonstrate how media systems influence individual behavior through normative structures and affective engineering. © 2025 Elsevier B.V., All rights reserved
Pupillographic evaluation accompanying structural and functional assessment of the optic nerve in patients with Parkinson's disease
Get PDFBackground To evaluate static and dynamic pupillary functions, contrast sensitivity, and retinal nerve fiber layer (RNFL) thickness in patients with Parkinson's disease. Methods The study included 25 right eyes of patients with Parkinson's disease (mean age: 67.88 +/- 9.40 years) and 26 right eyes of age- and sex-matched healthy controls (mean age: 64.15 +/- 7.60 years). Following the measurement of visual acuity and intraocular pressure, the RNFL thickness of the right eye was assessed using optical coherence tomography (Optovue, Inc., Fremont, CA, USA), and contrast sensitivity was measured with the CSV-1000E (Vector Vision, Dayton, OH, USA). Following a 5-minute period of dark adaptation, both static and dynamic pupillographic parameters were assessed using the Sirius corneal topography device (Sirius, CSO, Florence, Italy). Results There was no statistically significant difference between the groups in terms of age and sex (p = 0.126 and p = 0.579, respectively). RNFL thickness in the superior, inferior, nasal, and temporal quadrants of the right eye were as follows for Parkinson's and control groups, respectively: 133.6 +/- 18.03 vs. 144.73 +/- 17.44 mu m (p = 0.03), 122.0 +/- 14.47 vs. 134.96 +/- 25.28 mu m (p = 0.031), 67.76 +/- 12.05 vs. 74.65 +/- 12.05 mu m (p = 0.047), and 66.36 +/- 8.72 vs. 72.77 +/- 14.0 mu m (p = 0.057). A statistically significant thinning was observed in all quadrants except the temporal quadrant in Parkinson's patients (Fig. 1). Contrast sensitivity was significantly lower in the Parkinson's group across all spatial frequencies compared to controls (p = 0.03, 0.01, 0.05). Similarly, in dynamic pupillography, the pupil diameters at 0, 2, 4, 8, 12, and 16 s were smaller in the Parkinson's group, but no statistically significant differences were found between the groups (p > 0.05) (Fig. 3). Conclusions While a significant reduction in RNFL thickness and contrast sensitivity was observed in patients with Parkinson's disease, static and dynamic pupillographic parameters did not differ significantly between the groups. Therefore, the prognostic utility of pupillography in Parkinson's disease remains inconclusive and should be further investigated in larger and longitudinal studies
Comparison of a New Radiographic Technique with MRI Measurements for Tibial Tunnel Evaluation in ACL Reconstruction
Get PDFBackground/Objectives: The correct angular placement of the tibial tunnel is crucial to ensure graft tension, maintain knee stability, and ensure optimal clinical outcomes after anterior cruciate ligament (ACL) reconstruction. While 3D imaging methods such as MRI and CT are the gold standard for evaluating tunnel positioning, their routine use is limited by cost, availability, and time constraints. In clinical practice, 2D radiographs are more accessible but lack established reliability in accurately estimating tunnel angles. The aim of this study was to convert 2D radiographic angular measurements used in the evaluation of patients undergoing anterior cruciate ligament reconstruction into 3D values with a simple method and to compare these measurements with three-dimensional angles calculated using conventional MRI and CT. Methods: This retrospective study included 38 patients who underwent anatomic anterior cruciate ligament reconstruction. Postoperative radiographs and MR images were analyzed to determine the tibial tunnel angles. The angles calculated from 2D radiographs were statistically analyzed for their correlation with the actual 3D angles measured by MRI. Results: The analysis showed a strong correlation between tibial tunnel angles from radiographs and MRI, with minimal, non-significant differences. This suggests that radiographs can provide a reliable estimate of tibial tunnel angles. Conclusions: These findings suggest that radiographs can predict tibial tunnel angles in ACL reconstruction as accurately as MRI. This method can guide the correct tunnel angle and facilitate postoperative evaluation. Further studies are needed to confirm these results across various populations and techniques
Production of sustainable biocomposite materials developed using different agricultural waste powders as reinforcement
Get PDFThe use of agricultural wastes containing natural fibres in the materials industry within the framework of environmental approaches offers various opportunities such as efficient use of resources, waste management, carbon footprint reduction and sustainability. Biocomposite materials reinforced with agricultural wastes are one of the important approaches for sustainable waste management. In the study, mechanical, thermal and microstructural properties of biocomposite materials produced by mixing bioresin and waste walnut, hazelnut and rice husk powders were investigated. Thus, these wastes were ground with a ring mill and pulverized in the range of -77/+45 mu m. Biocomposite materials were produced by mixing 5 % by weight micropowders with epoxy resin. Tensile, three-point bending, izod impact and hardness tests were performed to determine the mechanical properties of the biocomposite materials. In addition, thermogravimetric analysis (TGA), differential thermal analysis (DTA) and scanning electron microscopy (SEM) analysis were performed on the biocomposite materials. The highest tensile strength was obtained in 5 % walnut powder-reinforced biocomposite material. All biocomposite materials had higher modulus of elasticity and lower elongation than the base material. After the base material, the highest flexural strength was obtained in the biocomposite material reinforced with 5 % rice husk powder. All reinforcing elements negatively affected the izod impact strength of the biocomposite materials. The base material and all biocomposites lost mass between approximately 200-600 degrees C.Duzce University Research Fund. [2022.11.01.1369]This study is supported by Duzce University Research Fund.

Evaluation of the effects of material and color use in architectural facade design on user perception: the Ankara-Çankaya example
Get PDFBinaların dış yüzü olan mimari cepheler, tasarımları ile kullanıcı ve kent arasında iletişimin kurulduğu ilk yer olup bir arayüz olarak değerlendirilmektedir. Mimari cephe tasarımında boyut, biçim, ölçek gibi parametrelerle birlikte en az bunlar kadar önemli yeri olan renk seçimi de binanın dış kabuğunu oluşturulan en önemli bileşenlerdendir. Son yıllarda, hızla artan nüfus ve kentlerin göç alması sebebiyle kentsel yapı ve bina tasarımları da yeni ihtiyaçlara göre değişmektedir. Bu değişiklikten renk faktörü de etkilenmektedir. Bu durumda malzeme, ürün, kullanıcı ve tasarımcı etkili olmaktadır. Bu çalışmada kullanıcı algısına göre tercihlerinin nasıl değiştiğinin, belirlenen çalışma alanları üzerinden incelenmesi amaçlanmıştır. Bu amaçla farklı konut ve konut grubu tasarımlarından Ankara ilinden üç örnek belirlenerek analiz edilmiş ve karşılaştırılmıştır. Çalışma alanı Türkiye'nin ilk toplu konut örneği 1940'larda planlanmış olan Saraçoğlu Mahallesi, Yeşiltepe blokları projesi ve günümüze yakın bir zamanda, 2015 sonrası planlanmış olan Merkez Ankara projesi konutlarından oluşmaktadır. Bu bağlamda seçilen örneklerin cepheleri incelenerek biçim, malzeme, doku ve renk üzerinden sorular hazırlanmış, ilgili projelerin cepheleri dijital olarak görselleştirilmiş ve anket çalışması ile desteklenerek insanların cephe tercihleri cephe tasarımı, uyumluluk, doluluk-boşluk, algı ve malzeme konusunda ilk görüşteki algıları üzerinden incelenmiştir. Çalışma sonunda elde edilen sonuçların kullanıcı algısını anlamada ve ileride konut ve konut grubu tasarımında cephe tasarımına ilişkin bir değerlendirme aracı olacağı öngörülmektedir. Benzer alan çalışmaları farklı bağlamlarda yapılması tasarımcıların ve kullanıcıların karar verme aşamasında ölçülebilir sonuçlar elde etmelerini sağlayabilecektir.Architectural facades, which are the outer faces of buildings, are the first place where communication is established between the user and the city with their designs and are considered as an interface. In architectural facade design, color selection, which is at least as important as parameters such as size, shape and scale, is one of the most important components that form the outer shell of the building. In recent years, urban structure and building designs have been changing according to new needs due to the rapidly increasing population and migration from cities. The color factor is also affected by this change. In this case, material, product, user and designer are effective. In this study, it is aimed to examine how user preferences change according to their perception through the determined study areas. For this purpose, three examples from different housing and housing group designs from Ankara province were determined, analyzed and compared. The study area consists of the first mass housing example of Turkey, the Saraçoğlu Neighborhood, Yeşiltepe Blocks Project, planned in the 1940s, and the Merkez Ankara project residences planned after 2015, close to today. In this context, the facades of the selected examples were examined and questions were prepared on form, material, texture and color, the facades of the relevant projects were visualized digitally and supported by a survey study, and people's facade preferences were examined on the basis of their first-view perceptions on facade design, compatibility, fullness-emptiness, perception and material. It is anticipated that the results obtained at the end of the study will be an evaluation tool in understanding user perception and in the future in the design of housing and housing groups. Conducting similar field studies in different contexts will enable designers and users to obtain measurable results in the decision-making phase
EXPLORING HAZELNUT SHELL-DERIVED CARBON AS AN ECO-FRIENDLY ADDITIVE IN BICYCLE TIRE MANUFACTURING
Get PDFRecently, the tire industry has focused on eco-friendly practices, particularly on integrating waste materials into rubber formulations. Natural alternatives to carbon have offered a promising way to lower the carbon footprint by promoting recycling. This study explored the incorporation of carbon derived from hazelnut shells (HSC), an agricultural byproduct, as an additive in bicycle tire manufacturing. Bicycle tire formulations were prepared by maintaining a constant total carbon filler content of 28 parts per hundred rubber (phr). Initially, 28 phr of commercial carbon black and 0 phr of HSC were used. In subsequent formulations, the carbon black content was gradually reduced to (21, 14, 7, and finally 0) phr, while the HSC content was correspondingly increased to (7, 14, 21, and 28) phr to replace the reduced commercial carbon black. The produced tires were analyzed using density measurements, Mooney viscosity (MV), Mooney scorch (MS), rheological evaluations, mechanical testing, scanning electron microscopy (SEM), thermogravimetric analysis (TGA), plunger tests, and rolling resistance tests. The study demonstrates that, although increasing the amount of HSC in tire compositions reduces the mechanical performance, the required performance standards for bicycle tires are still met.Duzce University Research Fund [2024.06.05.1481]This scientific study was conducted at the R&D Centre of Anlas Tyre Company.
