No full textBu çalışmanın amacı, mas güreşi sporcularının turnuva performans verilerinin üst gövde kuvveti/dayanıklılığı ve pastoral denge arasındaki ilişkilerini incelemektir Çalışmaya, Bursa Mas Güreş Topluluğu, mas güreşi turnuvasına katılan 30 erkek sporcu dahil edilmiştir. Sporculara ait antropometrik ölçümler alınmış ve el kavrama kuvveti, şınav, mekik, barfiks, denge testleri uygulanmıştır. Elde edilen veriler Statistical Package for Social Sciences for Windows (SPSS 25.0) istatistik paket programında değerlendirilmiştir Turnuva performansı ile fiziksel veriler arasındaki ilişkiler tanımlayıcı istatistikler, bağımsız gruplar t-testi, Pearson korelasyon analizi, tek yönlü ANOVA ve çoklu regresyon analizi ile değerlendirilmiştir. Bulgular, turnuvada başarılı olan sporcuların (çeyrek final ve üzeri) fiziksel profilinin, erken elenen sporculardan belirgin şekilde farklılaştığını göstermiştir. Kazanan sporcuların el kavrama kuvveti (ortalama 55+ kg), barfiks süresi (60+ saniye) ve denge testi süreleri (300+ saniye) anlamlı derecede yüksek bulunmuştur (p<0.01). Korelasyon analizi, maç kazanma oranı ile el kavrama kuvveti (r=0.72), barfiks süresi (r=0.68) ve denge testi süresi (r=0.64) arasında güçlü pozitif ilişkiler olduğunu ortaya koymuştur. Yapılan çoklu regresyon analizi, performans puanındaki değişimin %79'unun (R²=0.79) bu üç parametre tarafından açıklandığını ve en güçlü yordayıcının el kavrama kuvveti (β=0.52) olduğunu doğrulamıştır. Sonuç olarak, mas güreşi performansında üst vücut kuvveti (özellikle el kavrama), üst vücut dayanıklılığı ve dengenin kritik rol oynadığı tespit edilmiştir. Bu bulgular ışığında, mas güreşi sporcularının antrenman programlarının, bu fiziksel parametreleri geliştirmeye yönelik özel egzersizlerle desteklenmesi önerilmektedir.The purpose of this study is to examine the relationships between upper body strength/endurance and postural balance in tournament performance data of mass wrestling athletes. Thirty-two male athletes who participated in the mass wrestling tournament were included in the study. Anthropometric measurements were taken of the athletes, and hand grip strength, push-ups, sit-ups, chin-ups, and balance tests were applied. The obtained data were analyzed using the Statistical Package for Social Sciences for Windows (SPSS 25.0) statistical package program. The relationships between tournament performance and physical data were evaluated using descriptive statistics, independent samples t-test, Pearson correlation analysis, one-way ANOVA, and multiple regression analysis.The findings showed that the physical profiles of athletes who were successful in the tournament (quarterfinals and above) differed significantly from those who were eliminated early. Winning athletes had significantly higher handgrip strength (average 55+ kg), pull-up time (60+ seconds), and balance test time (300+ seconds) (p<0.01). Correlation analysis revealed strong positive relationships between match win rate and handgrip strength (r=0.72), pull-up time (r=0.68), and balance test time (r=0.64). Multiple regression analysis confirmed that 79% of the variance in performance scores (R²=0.79) was explained by these three parameters, with handgrip strength (β=0.52) being the strongest predictor. Conclusion: Upper body strength (especially handgrip), upper body endurance, and balance play a critical role in wrestling performance. In light of these findings, it is recommended that the training programs of mass wrestling athletes be supported with special exercises aimed at improving these physical parameters

No full textBu çalışmada, kedilerde görülen idrar yolu enfeksiyonlarının klinik, hematolojik, biyokimyasal ve sitolojik olarak değerlendirilmesi amaçlanmıştır. Gereç ve Yöntem Çalışmaya farklı yaş ve ırklardan, klinik şikayetleri arasında hematüri, pollaküri, strangüri, iştahsızlık ve kilo kaybı bulunan 10 kedi dahil edilmiştir. On adet sağlıklı kedi de kontrol grubunu oluşturmuştur. Her hastada:İdrar analizi (strip ve mikroskopi),Hematolojik inceleme (IDEXX ProCyte),Biyokimyasal inceleme (IDEXX Catalyst) yapılmıştır. Bulgular İdrar analizlerinde: Proteinüri (+2/+3),Hematüri (Hb +2/+4),Lökositüri (+2/+3),Bazı olgularda nitrit pozitifliği saptanmıştır. Sitolojik incelemelerde: Eritrositler,Epitel hücreleri,Bakteriler,Struvit ve kalsiyum oksalat kristalleri gözlenmiştir. Antibiyogram sonuçları bazı vakalarda negatif olmasına rağmen sitolojik incelemede bakteri varlığı dikkat çekici bulunmuştur. Bu durum, kültür sonuçlarının tek başına yeterli olmadığını ve klinik patolojide görsel değerlendirmenin tanıda kritik rol oynadığını göstermektedir. Hematolojik bulgularda bazı olgularda: Lökositoz Nötrofili İleri vakalarda anemi kaydedilmiştir. Biyokimyasal bulgular arasında kreatinin değerleri çoğunlukla normal sınırlar içinde bulunurken, üre bazı olgularda >130 mg/dL olarak ölçülmüştür. SDMA değerleri 8–48 µg/dL arasında olup yüksek değerlerin böbrek fonksiyon bozukluğu ile ilişkili olduğu belirlenmiştir. Sonuç Kedilerde FLUTD (Feline Lower Urinary Tract Disease) ile böbrek fonksiyon bozukluğu tablolarının birlikte görülebileceği anlaşılmıştır. SDMA ve üre değerleri, böbrek fonksiyon bozukluğunun erken göstergeleri olarak kullanılabilir. Kültür ve sitoloji sonuçları arasındaki tutarsızlıklar, görsel klinik patolojinin tanı ve tedavi sürecindeki önemini vurgulamaktadır.This study aimed to evaluate the clinical, hematological, biochemıcal and cytological findings of urinary tract infections in cats collectively. Materials and Methods: A total of 10 cats of different ages and breeds presenting with clinical signs including hematuria, pollakiuria, stranguria, anorexia, and weight loss were included in the study, along with 10 healthy cats as a control group. Urinalysis (dipstick and microscopy), hematological examination (IDEXX PROCYTE), and biochemical analysis (IDEXX CATALYST) were performed for all cases. Results: Urinalysis revealed proteinuria (+2/+3), hematuria (Hb +2/+4), leukocyturia (+2/+3), and nitrite positivity in some cases. Cytological examinations demonstrated the presence of erythrocytes, epithelial cells, bacteria, and struvite/calcium oxalate crystals. In some cases, although antibiogram results were negative, the presence of bacteria on cytological examination was noteworthy. This finding indicated that culture results alone may not be sufficient for diagnosis and highlighted the critical importance of visual evaluation in clinical pathology. Hematological findings showed leukocytosis and neutrophilia in some cases, while anemia was recorded in advanced cases. In biochemical analyses, creatinine levels were mostly within normal limits, whereas urea levels were measured above 130 mg/dL in some cases. SDMA values ranged between 8 and 48 µg/dL, and elevated values were found to be associated with renal dysfunction. Conclusion: FLUTD and renal dysfunction may occur concurrently in cats.Symmetrical dimethylarginine (SDMA) and urea values can be used as early indicators of renal dysfunction. Inconsistencies between culture and cytology results emphasize the importance of visual clinical pathology in the diagnostic and treatment processes
A novel five-term 3D chaotic system with two squared nonlinearities and its secure communication application for biomedical data
No full textEnsuring secure communication of biomedical data has become increasingly important due to its sensitive nature. Chaotic systems, with their inherent unpredictability and sensitivity to initial conditions, offer a promising approach for secure data encryption. This study introduces a novel five-term chaotic system that includes two squared nonlinearities, a unique configuration not previously reported in the literature. The system's dynamics are analyzed through equilibrium points, stability, bifurcation diagrams, and Lyapunov Exponents (LEs), where the Kaplan–Yorke dimension is found to be 2.1471 under selected parameters, confirming strong chaotic behavior. An electronic implementation of the system is achieved using standard analog components, validating its physical feasibility. The system is then applied to encrypt biomedical signals and images. In secure ECG signal transmission tests conducted on a Raspberry Pi, synchronization is achieved within 4 s using Sliding Mode Control (SMC). The encryption algorithm demonstrates high key sensitivity and a large key space. For biomedical image encryption, the proposed method achieves a Number of Pixels Change Rate (NPCR) of 99.56% and a Unified Average Changing Intensity (UACI) of 33.31%, indicating strong encryption performance. These results confirm that the proposed chaotic system is efficient, lightweight, and highly suitable for secure biomedical communication
Comprehensive characterization of butter fermented with region-specific starter cultures
No full textThis study investigated the strain-dependent effects of co-culturing region-specific Lactobacillaceae (L. casei, L. paracasei, and L. rhamnosus) with a conventional starter on the techno-functional properties of butter during storage. The incorporation of L. paracasei enhanced Lactobacillaceae viability on MRS agar (8.27 log CFU g−1; p −1; p < 0.01), and yielded the highest whiteness index (82.48; p < 0.01). L. rhamnosus was characterized by the highest firmness (6130.23 g; p < 0.01) and adhesiveness (−1807.87 g s; p < 0.01) values. Sensory analysis revealed that L. paracasei promoted creaminess and brightness, while L. rhamnosus enriched mouthfeel and sweetness perception. The experimental design involved examining the quality characteristics of butter samples inoculated with autochthonous strains, as well as a traditional starter culture, at various storage days (1st, 30th, 60th, and 90th day). The findings revealed strain-specific technological-functional and sensory improvements, demonstrating that autochthonous strains hold promising potential for the development of value-added butter products
A novel approach to treating canine otitis externa with medical ozone: A comparative clinical, cytological and microbiological research
No full textOtitis externa (OE), an inflammation of the external ear canal, is common in both humans and companion animals and often requires prolonged antimicrobial therapy. Ozone has gained attention for its antimicrobial, antiviral, and antioxidant properties in dermatologic disorders, although its optimal dose and route of administration remain unclear. This study aimed to evaluate the efficacy of topical ozone therapy for managing OE compared with conventional antimicrobial treatments. Twenty-seven client-owned dogs with OE were enrolled in an open-label, prospective, controlled clinical trial and assigned to three groups: ozone (Group I), ciprofloxacin drops (Group II), and a veterinary otic solution with florfenicol, terbinafine, and mometasone furoate (Group III). Clinical assessments (OTIS-3, otoscopy, pain, pruritus, cytology) were performed on days 0, 7, 14, and 21, with bacteriological evaluations on days 0 and 21. Based on OTIS-3, treatment success rates were 100 % in Group I, 33.33 % in Group II, and 66.66 % in Group III. Significant improvements in OTIS-3, otoscopy, pain, and pruritus scores were observed in Group I compared to Group II (p < 0.05). Cytological improvement was significant in Groups I (p < 0.001) and III (p = 0.003). Microbiological analysis confirmed the complete absence of bacterial growth in Group I, effectively eliminating Staphylococcus pseudointermedius, Proteus mirabilis, Bacillus spp., Citrobacter braakii, Coagulase-Negative Staphylococci, Escherichia coli, Dermacoccus nishiomiyaensis, and multidrug-resistant Acinetobacter baumannii. These findings highlight the potential of topical ozone therapy as a safe and effective option for the management of otitis externa, with important implications for reducing antimicrobial use and mitigating antimicrobial resistance

No full textExploring prospective teachers' intentions for artificial intelligence integration in education: The role of motivation
No full textUnderstanding motivational drivers behind prospective teachers' artificial intelligence (AI) integration intentions is critical. While prior models such as the technology acceptance model overlook motivational dynamics, this study used expectancy-value theory to assess how expectancy, attainment, utility, intrinsic value, and cost shape intentions. Data from 454 prospective teachers were analyzed via structural equation modeling using the Behavioral Intention Scale and the Questionnaire of Artificial Intelligence Use Motives. Utility value (beta = .29, p < .001) was the strongest predictor, followed by cost (beta = -.27), intrinsic value (beta = .25), attainment (beta = .21), and expectancy (beta = .10). The model explained 62% of variance in behavioral intention. Control variables, including gender, class level, and AI usage frequency, significantly influenced intentions. Findings suggested that teacher education programs should enhance AI's perceived utility, address implementation costs, and strengthen expectancy through training to foster adoption. Emphasizing AI's practical relevance within supportive environments can bridge its potential with classroom integration
Toward robust replay attack detection in automatic speaker verification: A study of spectrum estimation and channel magnitude response modeling
No full textAutomatic Speaker Verification (ASV) systems are increasingly adopted for biometric authentication but remain highly vulnerable to spoofing, particularly replay attacks. Existing countermeasures (CMs) for replay attack detection rely predominantly on discrete Fourier transform (DFT)-based spectral features, which are sensitive to noise and channel distortions common in physical access (PA) scenarios. This work presents the first comprehensive study of Channel Magnitude Response (CMR) representations for replay detection, explicitly analyzing the impact of spectrum estimation and feature design. The contribution of this work are fourfold: (i) CMR estimation is generalized beyond MFCCs to LFCC and CQCC features, with LFCC-based CMRs offering superior discrimination; (ii) alternative spectrum estimators - linear prediction (LP) and multitaper (MT) - are integrated into the CMR pipeline, yielding substantial gains over conventional DFT (iii) robustness is investigated under silence-free (voiced-only) conditions, mitigating known biases in ASVspoof datasets and (iv) a systematic evaluation of CMR is provided on the recently released ReplayDF corpus, a challenging benchmark combining replay and synthetic speech variability. Experiments on ASVspoof 2017, 2019, 2021, and ReplayDF using both baseline classifiers (ResNet18 and LCNN) and stronger models (Res2Net50 and SE-Res2Net50) show that the proposed approach consistently outperforms conventional features. Particularly, LFCC-CMR features with LP spectra achieve an Equal Error Rate (EER) as low as 1.34% on ASVspoof 2019 (PA), representing considerable relative improvements over traditional methods. Moreover, CMR-based systems retain high performance even when silent segments are removed, unlike conventional approaches. These results establish CMR with principled spectral modeling as a robust and generalizable framework for replay attack detection, opening new directions for resilient spoofing countermeasures
