No full textThe working group of the current study which aims at investigating the relation of isokinetic strength, shoulder mobility and ball velocity at elite female badminton players was made up of 28 female badminton players having the age, body weight and height means; 21,17±3,42 years, 62,47±8,60 kg, 164.31±5.88 cm and volunteering in the study. The data obtained in the study was analysed in the package program of SPSS (Statistical Package for Social Sciences) for Windows 22.0. For all variables in the study, Pearson correlation test was applied. In the research, 60˚/sec. dominant and non-dominant, internal and external isokinetic strength values (nm) were found as 37.05 ± 7.12, 36.95 ± 6.72, 26.87 ± 7.63, 22.27 ± 7.60 respectively. Dominant internal rotation values of the players were found as 57.37 ± 7.20, dominant external rotation values were found as 103.00 ± 8.08, non-dominant internal rotation values were found as 52.00 ± 4.92, non-dominant external rotation values were found as 97.35 ± 7.88. Shuttlecock velocity (km/h) was 238.45 ± 3.20. As a conclusion, upon the investigation of the correlation values between isokinetic strength, shoulder joint mobility and Shuttlecock velocity at elite female badminton players, a statistically direct re-lation was not found between them at the level of significance. </jats:p
Evaluating ChatGPT in Generating Feedback on Content and Organization Components of EFL Compare and Contrast Essays
No full textChatGPT, an innovative large language model that has impressed worldwide audiences with its exceptional generative capabilities, is now positioned to significantly transform the field of education. The purpose of this exploratory study is to investigate how accurately ChatGPT generates feedback on the content and organization components of EFL compare and contrast essays and the extent to which the feedback length provided by ChatGPT differs from that of the human teacher.To address these questions, a ChatGPT prompt incorporating evaluation criteria for content and organization components was developed, generating feedback on 10 compare and contrast student essays using the ChatGPT 3.5 version. The ChatGPT feedback and teacher feedback were assessed quantitatively and qualitatively according to the predetermined evaluation criteria. Furthermore, two types of feedback were compared descriptively and by conducting the Wilcoxon Sign Rank Test. The findings revealed that ChatGPT produced highly accurate feedback for both content and organization components, surpassing the teacher in the length of feedback provided. While the accuracy rate of the generated feedback was high, issues such as holistic assessment of the essay, false positives, failure to provide feedback where needed, and discrepancies in the depth of feedback compared to teacher feedback were identified. The results suggest that while ChatGPT shows promise in providing educational feedback, teacher-AI collaboration in giving feedback for EFL compare and contrast essays is important for delivering feedback that optimally benefits learners.</jats:p
İklim Değişikliğinde İnsan Unsuru ve İhmal Edilen Teolojik Boyut
No full textİklim değişikliğine dair muhtemel sebepler irdelenirken genellikle aşırı nüfus artışı ve ihtiyaca binaen gelişen sanayileşme olgusu gündeme getirilir. Bununla beraber çevre sorunlarının başta insan unsurundan kaynaklandığı düşünüldüğünde belirtilen sebeplerin yanı sıra bir de sanayileşme ile insanlarda gerçekleşen ahlâkî dönüşümün ve teolojik boyutun ihmali de etkili olmaktadır. Öyle ki ihmal edilen teolojik boyut ve zihinsel dönüşümle beraber âleme sırf maddi perspektiften yaklaşılarak buranın sadece tüketilmesi gereken bir alan olduğu düşünülmektedir. Tabiattan kopuşun sebebi olan bu süreç, iklim değişikliğinden bahsedilirken; sorunun teknik yönlerinin konuşulduğu gibi insan, din ve ahlak odaklı yönlerinin de konuşulması gerektiğini göstermektedir. Bu çalışma iklim değişikliğinde neredeyse hiç gündeme getirilmeyen teolojik boyutla sınırlandırılmıştır. Buna ek olarak literatürde az da olsa bu konu hakkındaki tartışmaların olduğu kaynaklar karşılıklı olarak değerlendirilmeye çalışılmıştır. Bu düzlemde özellikle teolojik boyutla desteklenmiş bir bakış açısının geliştirilmesi, sorunların asıl kaynağının tespitinde ve önlenmesinde etkileyici olacaktır. Diğer taraftan tüm insanları ilgilendiren böylesine küresel bir sorun karşısında, insanlığa dünya ve ahiret mutluluğunu vadeden İslâm dininin ne dediği merak uyandırmaktadır. Buradan hareketle bu makalede iklim değişikliğinde insan unsuru ve ihmal edilen teolojik boyut ele alınarak bu süreçte insanlığın yaşadığı bunalımlardan kurtulmada İslâm dininin evrensel mesajlarının katkısı üzerinde durulacaktır.</jats:p
Evaluation Of The Frequency, Localization And Relationship Of Maxillary Sinus Pathologies With Dental Pathologies By Cone Beam Computed Tomography (CBCT)
No full textBackground: The proximity of the root tips of the maxillary posterior teeth to the maxillary sinus causes odontogenic infection to become a potential source of maxillary sinusitis. This study aims to evaluate the relationship between dental pathologies and maxillary sinus abnormalities using cone beam computed tomography (CBCT). Material and Method: In this study, 300 patients who applied to our clinic for any reason 600 maxillary sinus cone beam computed tomography images of the patient were analyzed retrospectively. Maxillary sinus diseases and dental pathologies categoized among themselves. Results: The age of all patients ranged between 18 and 77 years, with a mean age of 41.38 (±14.39) years. No pathology was detected in 359 (59.8%) of the maxillary sinuses examined which were considered healthy sinuses. The most common pathology in 241 (40.2%) of the maxillary sinuses in the imaging area was mucosal thickening (MT). A statistically significant relationship was detected between teeth with periapical lesions (PL) and MT (p&lt;0.05). No statistically significant relationship was found between restorative applications, oro-antral fistula (OAF), periodontal bone loss (PBL), and maxillary sinusitis (MS) (p&lt;0.05). Conclusion: Odontogenic infections and inflammatory events are the causes of maxillary sinus pathologies and may play a role in their formation. CBCT, maxillary posterior teeth and maxillary sinüs in demonstrating the relationship between and in the diagnosis of odontogenous sinus pathlogies is quite useful.</jats:p

No full textImpact of triglyceride-glucose index on intracoronary thrombus burden in ST-elevation myocardial infarction patients undergoing primary percutaneous coronary intervention
No full textWe aimed to investigate the relationship between triglyceride glucose (TyG) index and intracoronary thrombus burden in patients with ST-elevation myocardial infarction (STEMI) who underwent primary percutaneous coronary intervention (PCI).A total of 468 consecutive patients who were admitted with STEMI and underwent primary PCI were included in the study. TyG index was calculated as ln [fasting triglycerides (mg/dL) × fasting plasma glucose (mg/dL)/2]. According to the angiographic reclassified thrombolysis in myocardial infarction (TIMI) thrombus grade, patients were divided into two groups as small thrombus burden (STB) with TIMI thrombus grade 0-3, and large thrombus burden (LTB) with TIMI thrombus grade 4-5. TyG index was significantly higher in the LTB group than in the STB group (9.11 ± 0.86 vs 8.89 ± 0.62; p = 0.002). In multivariate analysis, TyG index was found to be an independent predictor of LTB in STEMI patients who underwent primary PCI [OR (95 % CI): 1.470 (1.090-1.982), p = 0.012]. The area under the curve (AUC) of TyG index predicting LTB was 0.568 (95 % CI 0.506-0.631; p = 0.023), with the best cut-off value of 8.87. In the classification according to TyG index cut-off value, the frequency of LTB was found to be significantly higher in the high TyG index group than in the low TyG index group (33.6 % vs 21.2 %; p = 0.003).TyG index, a valid surrogate marker of insulin resistance, is an independent predictor of LTB in STEMI patients who underwent primary PCI and can be used as an indicator of increased intracoronary thrombus burden
Investigation of the Weldability of 3D-Printed Multi-Material Materials (PLA and PLA Wood) Using Friction Stir Welding
No full textIn the industry sector, it is very common to have different types of dissimilar materials on the same construction rather than products made from a single type of material. Traditional methods (welding, mechanical fastening, and adhesive bonding) and hybrid techniques (friction stir welding, weld bonding, and laser welding) are used in the assembly or joining of these materials. However, while joining similar types of materials is relatively easy, the process becomes more challenging when joining dissimilar materials due to the structure and properties of the materials involved. In recent years, additive manufacturing and 3D printing have revolutionized the manufacturing landscape and have provided great opportunities for the production of polymer-based multi-materials. However, developments in the joining of multi-material parts are limited, and their limits are not yet clear. This study focuses on the joining of 3D-printed products made from PLA-based multiple materials (PLA and PLA Wood) using friction stir welding. Single-material and multi-material parts (with 100% infill ratio and three different combinations of 50% PLA/50% PLA Wood) were welded at a feed rate of 20 mm/min and three different tool rotational speeds (1750, 2000, and 2250 rpm). Tensile and bending tests were conducted on the welded samples, and temperature measurements were taken. The fractured surfaces of the samples were examined to perform a damage analysis. It is determined that the weld strength of multi-materials changes depending on the combination of the material (material design). For multi-materials, a welding efficiency of 74.3% was achieved for tensile strength and 142.68% for bending load.</jats:p
Attitudes, Prejudices and Barriers of Healthcare Professionals towards Female Patients with Obesity
No full textABSTRACT Objective: This descriptive and correlational study was conducted to evaluate the attitudes, prejudices, and patient care obstacles of healthcare professionals (HPs) who work in the healthcare and allied healthcare services and serve female patients with obesity in Türkiye. Materials and Methods: The sample of the study included 411 HPs who provided care to female patients in public and university hospitals in Türkiye and who volunteered to participate in this study. Data were collected online using an Information Form, GAMS-27 Obesity Prejudice Scale (GAMS-27), the Attitudes Toward Obese People Scale (ATOP), and the Questionnaire on Patient Care Obstacles for Patients with Obesity (OHBEF). Results: The mean scores of HPs on the abovementioned scales were OHBEF= 65.09±8.80, GAMS-27= 77.91±4.52, and ATOP= 59.24±0.23. The mean score of HPs on the OHBEF was related to age, mean Body Mass Index (BMI) of men, and occupational group (p0.05). Conclusions: This study revealed that HPs had prejudiced and negative attitudes toward female patients with obesity, and this was related to a lack of materials and equipment for patient care, sex, age, BMI, and occupational group.</jats:p
