The impact of language variability on artificial intelligence performance in regenerative endodontics
Get PDFRegenerative endodontic procedures (REPs) are promising treatments for immature teeth with necrotic pulp. Artificial intelligence (AI) is increasingly used in dentistry; thus, this study evaluates the reliability of AI-generated information on REPs, comparing four AI models against clinical guidelines. Methods: ChatGPT-4o, Claude 3.5 Sonnet, Grok 2, and Gemini 2.0 Advanced were tested with 20 REP-related questions from the ESE/AAE guidelines and expert consensus. Questions were posed in Turkish and English, with or without prompts. Two specialists assessed 640 AI-generated answers via a four-point rubric. Inter-rater reliability and response accuracy were statistically analyzed. Results: Inter-rater reliability was high (0.85–0.97). ChatGPT-4o showed higher accuracy with English prompts (p < 0.05). Claude was more accurate than Grok in the Turkish (nonprompted) and English (prompted) conditions (p < 0.05). No model reached ≥80% accuracy. Claude (English, prompted) scored highest; Grok-Turkish (nonprompted) scored lowest. Conclusions: The performance of AI models varies significantly across languages. English queries yield higher accuracy. While AI shows potential for REPs information, current models lack sufficient accuracy for clinical reliance. Cautious interpretation and validation against guidelines are essential. Further research is needed to enhance AI performance in specialized dental fields
Investigation of the Ku band electromagnetic properties of red mud sintered by different methods
Get PDFThe main objective of this study is to reveal the potential of using red mud, a significant metallurgical waste, as an electromagnetic wave absorber material. In this study, initially, red mud obtained from the aluminium sector was analysed physically, chemically, mineralogically, and thermally. Subsequently, samples produced using three different methods (dry-sintered, slip casting-sintered, and mechanically pressed-sintered) were characterized in the Ku band range using a Vector Network Analyzer (VNA) and waveguide measurement kit (WR62) and the EM properties including permittivity and permeability were compared. Permittivity, permeability and loss tangents of the materials corresponding to the Ku band of materials were given. The analysis revealed that the main parameters affecting EM properties are particle size and porosity ratio. In this context, the slip casting-sintered red mud sample showed higher tanδε and tanδμ values compared to the other two production methods. In addition, reflection loss (RL) values of materials were obtained and compared. The study concluded that the shaping method affects the EM properties and holds promise for the use of red mud as an electromagnetic wave absorber material
Comparison of policy topics related to urbanization in Türkiye's development plans: An evaluation of the tenth, eleventh, and twelfth development plans
Get PDFBu çalışmada, Türkiye’nin Onuncu, On Birinci ve On İkinci Kalkınma Planları çerçevesinde şehirleşme politikaları incelenmiştir. Her üç plan da ülkenin kalkınmasında önemli rol oynamış, ancak hedeflere ulaşma oranlarında farklılıklar görülmüştür. Onuncu Kalkınma Planı, şehirleşmeyi sürdürülebilir ekonomik kalkınma aracı olarak ele alırken, On Birinci ve On İkinci Planlar çevre koruma, afet yönetimi ve kentsel dönüşüm gibi temalara odaklanmıştır. Özellikle, 2023 Kahramanmaraş depremleri sonrası afetlere dayanıklı yapılar inşa edilmesi ve risklerin azaltılması gerektiği vurgulanmıştır. Kentsel dönüşüm ve sosyal konut üretimi, her üç planda önemli yer tutmuş ancak uygulama ve finansal stratejiler farklılaşmıştır. Bölgesel gelişim ve kırsal kalkınma da önemli başlıklar olmasına rağmen, bölgesel gelişmişlik farkları artmış, kırsaldan kente göçün önlenmesi konusunda yeterli ilerleme sağlanamamıştır. Çalışmada elde edilen bulgular, kalkınma planlarında devamlılık sağlanamadığını, belirlenen hedeflere ulaşmanın zorlaştığını ve planlar arasındaki uyum eksikliklerini ortaya koymuştur. Sonuç olarak, bu çalışmanın bulguları, Türkiye’nin şehirleşme politikalarını geliştirmek için yenilikçi, esnek ve toplumun farklı kesimlerini kapsayan yeni politikaların gerekliliğini ortaya koymaktadır. Gelecekteki kalkınma planlarında, afet yönetimi, sürdürülebilir altyapı ve bölgesel kalkınma gibi temel hedeflerin ön plana çıkarılması gerekir.In this study, urbanization policies within the framework of Türkiye's Tenth, Eleventh, and Twelfth Development Plans are examined. All three plans have played a significant role in the country's development; however, there have been differences in the rates of achieving the set goals. The Tenth Development Plan addressed urbanization as a tool for sustainable economic development, while the Eleventh and Twelfth Plans focused on themes such as environmental protection, disaster management, and urban transformation. Particularly, after the 2023 Kahramanmaraş earthquakes, the need to build disaster-resistant structures and reduce risks was emphasized. Urban transformation and the production of social housing have been central topics in all three plans, but the implementation and financial strategies have varied. Although regional development and rural development were also important areas, regional development disparities have increased, and insufficient progress has been made in preventing rural-to-urban migration. The findings of the study reveal that continuity could not be achieved in the development plans, making it difficult to reach the established goals, and highlight the lack of coordination between the plans. In conclusion, the findings of this study underscore the need for innovative, flexible, and inclusive policies that encompass various segments of society to improve Türkiye’s urbanization policies. Future development plans should prioritize key goals such as disaster management, sustainable infrastructure, and regional development
The phenomenon of migration in the institutional reports of development agencies: policy and practice in the case of Türkiye
Get PDFTürkiye Cumhuriyeti Devleti sahip olduğu jeo-politik ve jeo-ekonomik konumundan dolayı yüzyıllar boyunca göç hareketlerinin çekim merkezi olmuştur. Yapılan göçlerin her birinin farklı türleri ve gerekçeleri olsa da yol açtığı sonuçlar birbirleriyle benzerlik göstermektedir. Gerek iç göç gerek dış göç olsun göç alan bölgeler sosyal, ekonomik, mekânsal ve kültürel yönlerden etkilenmektedir. Bölgesel kalkınmayı sekteye uğratmamak için bölge ve göç alan yerler arasındaki etkileşimin doğru analiz edilip hedef bölgenin sahip olduğu dinamiklere göre bölgesel stratejik önceliklerin ortaya konulması gerekmektedir. Çalışmada “Türkiye’deki kalkınma ajansları göç olgusuna nasıl yaklaşmaktadır?” sorusuna yanıt aranmıştır. Bu kapsamda Türkiye’de farklı bölgelerde yer alan kalkınma ajanslarının göç olgusuna ilişkin politikaları 2014-2023 dönemlerini kapsayan bölge planları üzerinden incelenmiştir. Bu politikaların gerçekleştirilmesine yönelik somut uygulamalar ise Türkiye’deki kalkınma ajanslarının farklı yıllara ait Faaliyet Raporları ve Çalışma Programları çerçevesinde irdelenmiştir. Çalışmada nitel araştırma yöntemleri içerisinde yer alan doküman analizi tekniğinden istifade edilmiştir. Elde edilen bulgular betimsel olarak açıklanmaya çalışılmıştır. Çalışmanın sonucunda kalkınma ajanslarının göç olgusuna ilişkin yaklaşımlarının ekseriyetle tersine göç politikaları; kentsel baskılar, fiziksel ve sosyal hizmet yönetimi; istihdam, eğitim, girişimcilik tabanlı göç politikaları; kırsal kalkınmayla göçü azaltma politikaları ile göç analizi, yönetişim ve izleme faaliyetleri bağlamında şekillendiği anlaşılmıştır.The Republic of Türkiye has been a centre of attraction for migration movements for centuries due to its geo-political and geo-economic position. Although each of the migrations has had different types and reasons, the problems caused by them are similar to each other. Whether internal migration or external migration, the regions receiving migration are affected in social, economic, spatial and cultural dimensions. In order not to disrupt regional development, the interaction between the region and the places receiving migration should be analysed correctly and regional strategic priorities should be put forward according to the dynamics of the target region. In this study, it has been tried to answer the question “how do development agencies in Türkiye approach the phenomenon of migration?”. In this context, the policies of development agencies in different regions of Türkiye on the phenomenon of migration have been examined through regional plans covering the period 2014-2023. Concrete practices for the implementation of these policies are reviewed through the annual reports and work programmes of development agencies in Türkiye for different years. The findings obtained were tried to be explained descriptively. The study concluded that development agencies' approaches to migration issues are predominantly shaped by return migration policies; urban pressures, physical and social service management; employment, education, and entrepreneurship-based migration policies; rural development policies aimed at reducing migration; and migration analysis, governance, and monitoring activities
An explainable prediction model for drug-induced interstitial pneumonitis
Get PDFDrug-induced interstitial pneumonitis (DIP) is an inflammation of the lung interstitium, emerging due to the pneumotoxic effects of pharmaceuticals. The diagnosis is challenging due to nonspecific clinical presentations and limited testing. Therefore, identifying the risk of drug-related pneumonitis is required during the early phases of drug development. This study aims to estimate DIP using binary quantitative structure-toxicity relationship (QSTR) models. The dataset was composed of 468 active pharmaceutical ingredients (APIs). Five critical modeling descriptors were chosen. Then, four machine-learning (ML) algorithms were conducted to build prediction models with the selected molecular identifiers. The developed models were validated using the internal 10-fold cross-validation and external test set. The Logistic Regression (LR) algorithm outperformed all other models, achieving 95.72% and 94.68% accuracy in internal and external validation, respectively. Additionally, the individual effect of each descriptor on the model output was determined using the SHapley Additive exPlanations (SHAP) approach. This analysis indicated that the pneumonitis effects of drugs might predominantly be attributed to their atomic masses, polarizabilities, van der Waals volumes, surface areas, and electronegativities. Apart from the strong model performance, the SHAP local explanations can assist molecular modifications to reduce or avoid the risk of pneumonitis for each molecule in the test set. Contributing to the drug safety profile, the current classification model can guide advanced pneumotoxicity testing and reduce late-stage failures in drug development
A reaction based fluorescent sensor for the detection of histamine and its application in fish samples
Get PDFHistamine (His) is responsible for the toxicity related to seafood consumption.However, standard detection methods do not currently meet rapid His analysis requirements. In this study, we developed an anthracene-based fluorescent sensor synthesized from the reaction of3-chloroisonicotinaldehyde and anthracen-9-ylmethylene-hydrazine. UV–Vis and fluorescence spectroscopy were used to determine the selectivity of the sensor in the existence of a range of biogenic amines. FZ-2 showed high sensitivity and selectivity towards His compared to various other biogenic amines in acetonitrile (ACN)/Acetate buffer (10 mM, pH 6.5, v/v, 1:1).The specific response to His was obtained by the substitution reaction of the primary amine of His with chlorine in the pyridine moiety of the sensor. A linear relationship was found between His concentration and fluorescence response of FZ-2 within the range 3.0–50.0 μM. The detection limit was calculated as 2.19 μM. Moreover, FZ-2 was able to monitor His in fish samples using fluorescence spectroscopy
