Reklamlar ürünlerin duyurulması, tanıtılması ve ardından satışının artırılması için tasarlanan ürünlerdir. Amaç ilgili ürünle ilgili çekicilik oluşturularak talep edilir hâle getirilmesidir. Bu amaçla reklamlarda kimi imgeler kullanılır ve zamanla bu imgeler genel geçer kabuller hâline gelebilir. Çünkü tüketici sıklıkla aynı şeyle karşılaştıkça zihninde belli imajlar oluşacaktır. Çalışmanın temel varsayımı, reklam içeriklerindeki tip/karakter ve temsillerin, tüketicilerin kendi zihinsel imgeleriyle örtüştüğünde ürün veya hizmete yönelik olumlu bir anlamlandırma oluşturduğu düşüncesidir. Bu kapsamda araştırmanın amacı, reklam filmlerinde kullanılan tipleme ve karakter temsillerinin, kültürel temsil biçimleri aracılığıyla tüketici zihninde marka algısını nasıl inşa ettiğini incelemektir. Bu çalışmada Doğuş Çay reklamlarında kullanılan Karadenizli tipinin nasıl bir imaja dönüştüğü ve bu imajın hangi aracılarla oluşturulduğu tartışılmıştır. En çok tercih edilen çay markalarından olan ve reklamlarında Karadeniz ve çay ilişkisinden oldukça faydalanan Doğuş Çay’ın yedi reklam filmi örneklem olarak alınmış ve değerlendirilmiştir. Çalışmada nitel araştırma türlerinden betimsel analiz yöntemiyle çözümleme yapılmıştır. Amaçlı örnekleme tekniği kullanılarak seçilen yedi adet reklam filminden oluşan örneklemden yola çıkılarak markanın çay reklamlarındaki Karadenizli tipinin nasıl temsil edildiği ortaya koyulmuştur. Reklam filmlerine youtube ve instagram platformları üzerinden ulaşılmıştır. Bu yöntem aracılığıyla reklamlarda Karadenizlinin belli noktaları vurgulanarak kullanıldığı ve bu tekrarın hedef kitlenin belleğindeki Karadenizli imajının oluşmasında ve sürmesinde etkili olduğu sonucuna ulaşılmıştır. Reklamlarda Karadenizli tipi çay ve Karadeniz arasındaki ilişkiyi vurgulamak için sıklıkla kullanılmaktadır. Bu kullanışlar zamanla tek tipleşerek tüm Doğu Karadenizlileri temsil eden birer tipe dönüşmektedir. Bu temsillerin niteliği insanların kafalarındaki Karadenizli imajını da etkilemektedir. Kötü temsil tekrar ettiğinde insanların kafasında gerçek o temsille kodlanmakta ve bir süre sonra medyada karşılaşılan tipler gerçek olarak algılanabilmektedir. Çalışmada müzik, etnografik malzeme, mekân ve ağız özellikleri başlıkları üzerinden Karadenizlinin çay reklamlarında temsili ele alınan yedi reklamdan hareketle tartışılmıştır. Çalışmada, Karadenizli tiplemesinin reklam içeriklerinde nasıl inşa edildiği, hangi kültürel ve sosyal ögelerle pekiştirildiği ve bu strateji üzerinden hedef kitle ile nasıl bir bağ kurulduğu ortaya konmuştur. Bulgular, Karadenizli imgesinin reklam filmleri aracılığıyla güçlendirilerek marka ile özdeşleştirildiğini göstermektedir. Sonuç olarak, bu temsilin hem tüketicide bölgesel aidiyet duygusunu harekete geçirdiği hem de markanın ulusal ölçekte samimi ve güvenilir bir kimlik kazanmasına katkı sunduğu tespit edilmiştir.

Bu araştırma, Türkiye’de kamu personel rejiminin temel normatif çerçevesini oluşturan 657 sayılı Devlet Memurları Kanunu (DMK) üzerine hazırlanmış lisansüstü tezlerin tematik ve yapısal eğilimlerini ortaya koymayı amaçlamaktadır. Çalışmada, 2009–2024 yılları arasında yayımlanmış ve erişime açık olan on bir lisansüstü tez, içerik çözümlemesi ve ağ analizi yöntemleri kullanılarak incelenmiştir. Tezler; tema dağılımları, anahtar kavramlar, atıf yapılan kanun maddeleri, yargı kararlarının yoğunluğu, anabilim dalları ve yıllara göre üretim eğilimleri ölçütleri üzerinden analiz edilmiştir. Bulgular, literatürde disiplin hukuku temasının belirgin biçimde baskın olduğunu ve kavramsal yoğunlaşmanın “disiplin”, “ceza”, “memur” ve “yargı” ekseninde şekillendiğini göstermektedir. Ayrıca çalışmaların büyük ölçüde yüksek lisans düzeyinde ve kamu hukuku odaklı olduğu, yönetsel ve disiplinler arası yaklaşımların sınırlı kaldığı tespit edilmiştir.

ABSTRACT Burdur Lake is a saline lake in southwestern Türkiye that has lost approximately 75 km 2 , or one‐third of its surface area, since 1975. The basin's hydrology has been significantly modified by human activities, including reservoir construction, and water level declines continue with no signs of stabilisation. In this study, the soil and water assessment tool (SWAT) was employed to simulate the hydrological processes in the Burdur Lake Basin and analyse the cumulative impacts of climate change and hydrological modifications. The model incorporated a digital elevation model, land use/cover and soil maps and historical meteorological data. Calibration and validation were performed using the SUFI‐2 algorithm within SWAT‐CUP, based on streamflow and water volumes in major reservoirs and Burdur Lake. Future hydrological conditions were projected by running bias‐corrected precipitation and temperature data from three global climate models (GFDL‐ESM2M, HadGEM2‐ES, MPI‐ESM‐MR) under RCP4.5 and RCP8.5 scenarios for 2025–2098. Results indicate that the Burdur Lake Basin can face a 5%–10% decrease in precipitation under RCP4.5 and a 14%–20% decrease under RCP8.5, with minimum and maximum temperatures rising by about 5°C relative to historical values. Simulated lake volumes and levels show continued declines, with water levels falling below the ecological threshold of 835 mASL under all RCP8.5 projections and the HadGEM2‐ES RCP4.5 scenario. Although the decrease in water level is slower than in the historical period, the downward trends are projected to continue. This study shows that climate change could create additional stressors on the already altered hydrological conditions of Burdur Lake. Implementation of adaptive and integrated water management strategies is essential to prevent further degradation in the lake's ecological and hydrological balance.

The practice of simulation-based learning now appears in dysphagia training because it enables healthcare professionals to practice their skills through controlled sessions which help them build their abilities while maintaining patient safety. Simulation provides essential value to competency-based training because traditional placement sites do not guarantee consistent availability of complex swallowing cases. Research findings show that participants who take part in simulated learning activities develop their diagnostic reasoning abilities and their assessment skills and their confidence levels and their communication abilities. The advantages of this technology have been documented in studies which used it for pediatric feeding, adult dysphagia assessment and treatments. The simulation environment enables students to receive directed feedback which enables them to develop their skills through multiple attempts before they interact with actual patients. Through simulation students can develop their clinical judgment while connecting theoretical knowledge to practical applications.

Despite increasing interest in patient-reported outcomes in implant dentistry, there is a lack of consensus on tool selection and outcome prioritization to assess patient-reported outcomes in implant dentistry. This study validates an instrument designed to support clinicians in evaluating patient experience and knowledge for personalized implant therapy. Patients with dental implants that had been functioning for at least one year were included in this cross-sectional study. A five-point Likert questionnaire (Implant Treatment Experience and Knowledge Scale; ITEKS) was administered to measure patients' perceived knowledge of peri-implant health/disease and their satisfaction with the treatment. The reliability of the questionnaire was analyzed using Cronbach's alpha. Exploratory factor analysis was used to examine the underlying structure of the questionnaire. Correlations between the OHIP-14, a widely used instrument for assessing oral health-related quality of life, and the administered scales were analyzed to examine convergent validity. The potential influence of patient-related factors (age, gender, education, source of information, and peri-implant diagnosis) was investigated. A 28-item tool was used to assess dental implant treatment related awareness, satisfaction, post-treatment attitudes, and the etiology, treatment, and risk factors of peri-implantitis. The mean functional time of dental implants was 6.69 years. Psychometric properties were evaluated using exploratory factor analysis and Cronbach's alpha. Cronbach's alpha values for these tools were.864 and.779, respectively. Peri-implantitis was significantly associated with decreased patient satisfaction (p < .001). No statistically significant gender differences were observed for OHIP, Implant Treatment Experience Metric (ITEM), or Implant Patients Knowledge-Awareness Scale (IPKAS) scores (p > .05). Participants with advanced education exhibited significantly higher ITEM scores than those with basic education (p = .028). Furthermore, OHIP scores were significantly higher in the peri-implantitis group compared to both the peri-implant health and peri-implant mucositis groups (p < .001). Conversely, ITEM scores were significantly lower in the peri-implantitis group compared to the health and mucositis groups (p < .001). The instrument demonstrated methodological suitability for assessing patient-related outcomes in individuals undergoing implant treatment, as confirmed by reliability and validity tests. These results indicate that the ITEKS is a reliable and valid instrument for assessing patient experience in implant dentistry.

This study proposes a vision-based deep learning approach for unmanned aerial vehicle (UAV) altitude estimation as an alternative to traditional methods such as GPS, barometric sensors, and laser altimeters, which are often sensitive to environmental disturbances. A large-scale dataset of 303,710 nadir images was collected using Mavic 2 Pro and Mavic 2 Zoom platforms under diverse weather, illumination, and terrain conditions. Each image was labeled with above-ground-level (AGL) altitude by integrating EXIF-based GPS altitude with a 30 m Digital Elevation Model (DEM) through coordinate transformation and terrain subtraction. A pre-trained ResNet50 model, originally designed for image classification, was reconfigured as a regression network and fine-tuned for 200 epochs using the Adam optimizer and mean squared error (MSE) loss. The proposed model achieved a mean absolute error (MAE) of 4.09 m in urban areas and 6.06 m in rural areas, with R^2 scores of 0.9981 and 0.9804, respectively. Comparative experiments with alternative CNN architectures show that the adapted ResNet50 provides favorable accuracy versus complexity trade-off. These results indicate that the proposed monocular, nadir-image-based framework can serve as a reliable complement or alternative to conventional altitude sensors in UAV operations.

Objective: This study aimed to investigate the effects of Perga supplementation on glucose metabolism, body weight regulation, and amyloid-beta (Aβ) accumulation in a streptozotocin (STZ)-induced type 2 diabetes (T2D) rat model, focusing specifically on insulin, leptin, and fibroblast growth factor 21 (FGF21) signaling pathways. Methods: Male Wistar rats were divided into Sham (S), T2D, and T2D+Perga (T2DP) groups. T2D was induced by a single intraperitoneal (i.p.) STZ injection (60 mg/kg). Perga (200 mg/kg/day) was administered to the T2DP group by gavage 14 days after diabetes induction. Plasma and brain insulin and leptin levels, liver and plasma FGF21 concentrations, Homeostasis Model Assessment of Beta Cell Function (HOMA-β) index, fasting glucose levels, body weight changes, and brain amyloid-beta (Aβ) accumulation were evaluated. Results: STZ-induced T2D resulted in hypoinsulinemia, decreased HOMA-β scores, weight loss, reduced plasma leptin, increased brain leptin, decreased FGF21 levels, and significant Aβ accumulation in the hippocampus. Perga treatment significantly improved plasma and brain insulin levels, increased HOMA-β, reduced fasting glucose, and attenuated weight loss. Plasma leptin levels returned to normal, brain leptin levels decreased, and hippocampus Aβ burden was significantly reduced. In addition, perga supplementation almost normalized liver and plasma FGF21 levels. Conclusion: Perga supplementation effectively ameliorates metabolic dysfunction and neurodegenerative markers in the T2D model. Its regulatory effects on insulin, leptin, and FGF21 signaling highlight its potential as a natural therapeutic agent in managing T2D and associated AD-like pathology. Further research is needed to evaluate its clinical applicability.

The Internet of Things (IoT) has improved efficiency and quality of life by connecting devices to the internet. It has seen success in areas such as smart vehicles and Unmanned Aerial Vehicles (UAVs), but faces processing limitations due to the need to send large amounts of data to other devices for processing. When heavy processing is required, it uses offloading techniques to send the data to other devices for processing. Secure data offloading transmission remains a fundamental challenge in this field. This paper presents an innovative authentication and key exchange method that uses Elliptic Curve Cryptography (ECC) and incorporates Handover for secure offloading, offering a safe, lightweight solution within a blockchain network. To evaluate the resistance of the proposed scheme against active and passive attacks, we employed the AVISPA tool to apply both formal and informal methods. Subsequently, to demonstrate the scheme's lightweight nature, we examined it with respect to computation and communication costs, the number of bits used, and security requirements. Additionally, we simulated the proposed scheme using the NS3 tool in two scenarios: urban and highway, with varying numbers of vehicles. The results indicate that the proposed scheme performs acceptably in urban and highway scenarios.
