Article Buckwheat Starch–Myristic Acid Complex Formation: Effect of Reaction Temperature and Myristic Acid Concentration on Digestibility Properties(2022) Aydemir, Levent Yurdaer; Ozbey, Ayse; Kahraman, Kevser; Emlek, Betül OskaybaşBu çalışma, farklı miristik asit konsantrasyonları ve farklı reaksiyon sıcaklıkları kullanılarak üretilen karabuğday nişastası-miristik asit kompleksi örneklerinin sindirilebilirlik özellikleri üzerine farklı reaksiyon koşullarının etkisini araştırmayı amaçlamıştır. Reaksiyon sıcaklığının (60-90°C) ve yağ asidi konsantrasyonlarının (0.1-0.8 mmoL/g) sindirilebilirlik özellikleri üzerindeki etkisini araştırmak için Yanıt Yüzey Metodolojisi kullanılmıştır. Örneklerin enzime dirençli nişasta (EDN) içerikleri reaksiyon sıcaklığındaki artışla artmıştır. Reaksiyon sıcaklığı, örneklerin hızlı ve yavaş sindirilebilir nişasta içeriklerini etkilemiştir. En yüksek EDN içeriği (%32.57) 90°C'de 0.45 mmoL/g miristik asit kullanılarak üretilen örnekte elde edilmiştir. F, p (<0.05) ve R2 değerleri seçilen modellerin numunelerin sindirilebilirlik özellikleri için önemli olduğunu göstermiştir. Karabuğday nişastasının miristik asit ile kompleks oluşturması, EDN içeriğini artırma konusunda umut verici görünmektedir. Karabuğday, çalışmalar henüz oldukça yeni olmasına rağmen, EDN kaynağı olarak önemli bir potansiyele sahip görünmektedir.Conference Object Citation - Scopus: 1Semantic-Forward Relaying for 6G: Performance Boosts With ResNet-18 and GoogleNet Plus(Institute of Electrical and Electronics Engineers Inc., 2024) Erkantarci, Betul; Çoban, Mert Korkut; Bozoǧlu, Abdulkadir; Köse, AbdulkadirThis paper investigates the integration of advanced deep learning architectures, namely ResNet-18, GoogleNet and enhanced GoogleNet (GoogleNet Plus), into the Semantic-Forward (SF) relaying framework for cooperative communications in 6G networks. The SF relaying framework enhances transmission efficiency and robustness by leveraging semantic information at relay nodes. We analyze and compare the performance of these deep learning models in terms of validation accuracy, semantic accuracy, and Euclidean distance (ED) metrics on the CIFAR-10 dataset. Results indicate that ResNet-18 achieves the highest performance due to its residual learning architecture. GoogleNet Plus, incorporating Automatic Mixed Precision (AMP) training and the Adam optimizer, demonstrates improved stability and efficiency compared to the original GoogleNet. The results highlights the potential of deep learning models to enhance semantic processing capabilities in SF relaying, contributing to the development of more efficient, resilient, and adaptive cooperative communication systems in 6G networks. © 2025 Elsevier B.V., All rights reserved.Article Sustainable Conservation Through the Interrelations Between Rural Architecture and Life: The Case of Çomakdağ(Emerald Group Publishing Ltd, 2025) Kurtulus, Vacide Betul; Guchan, Neriman SahinPurposeThe paper aims to propose a new approach to the sustainable conservation of rural heritage with the aim of understanding the relations between built environment and society. In the document "Concerning Rural Landscapes as Heritage" by ICOMOS-IFLA, it is argued that there is an interaction between daily life practices and the physical environment for production and cultural activities (ICOMOS, 2017). The main objective of the study is to underline the importance and necessity for this interaction continue for the sustainable conservation of rural areas.Design/methodology/approachThis paper investigates the relationship between the built environment and daily practices in Turkey's & Ccedil;omakdag Region, known for its significant rural architecture and enduring traditions. Through on-site investigation, the study explores the evolution of these relationships across various scales, including buildings, settlements and the region itself. This multi-scale approach aims to identify remaining cultural values and user needs.FindingsTraditional ways of life have undergone a transformation, impacting the interactions between inhabitants and their natural, agricultural and architectural spaces. The primary drivers of these changes are shifts in income sources, technological advancements and infrastructural developments within the settlements. While maintaining a connection between the built environment and daily life practices remains essential, contemporary living conditions and altered routines present challenges to this continuity.Originality/valueThis study builds on previous research on the & Ccedil;omakdag Region. Batur (2010) explored the region's architectural features, including colors and ornamentation. Kurtulus and G & uuml;& ccedil;han (2020) focused on Kizilaga & ccedil; village, examining typical house characteristics. This research offers a new perspective on rural heritage preservation. It emphasizes the importance of maintaining the interrelationship between daily life and the built environment across various scales for sustainable conservation.Research Project Karabuğday Nişastasından Yenilebilir Film Üretimi ve Nişastanın Yağ Asitleri ile Modifikasyonunun Film Mekanik Özellikleri Üzerine Etkisi(TÜBİTAK, 2022) Kahraman, Kevser; Aydemir, Levent Yurdaer; Koca, Esra; Oskaybaş Emlek, BetülBu proje, karabuğdaydan yüksek saflıkta ve verimde nişasta üretilmesini, üretilen nişastanın çeşitli yağ asitleri (10C, 14C, 18C) kullanılarak elde edilen amiloz-lipit kompleksinden film üretimini amaçlamaktadır. Amiloz-lipit kompleksi üretiminde herbir yağ asidi için en etkili iki reaksiyon parametresi (sıcaklık, süre, pH, yağ asidi/nişasta oranı) belirlenmiştir. Herbir yağ asidi için en etkili iki parametre kullanılarak merkezi kompozit tasarım ile deneme tasarımları oluşturulmuş, komplekslerin kompleks indeks (KI), görünür amiloz, sindirilebilirlik, su bağlama-çözünürlük, çirişlenme, berraklık ve sineresis derecesi gibi özellikleri açısından karakterize edilmiştir. Kompleks oluşumunun nişastanın yapısına etkisi XRD ve FT-IR ile incelenmiştir. Amiloz-lipit kompleks oluşumu ile nişastanın enzime dirençli nişasta miktarı artmış, şişme gücü azalmıştır. En yüksek KI değerine sahip amiloz-kompleksi içeren nişastalar kullanılarak gliserol varlığında filmler üretilmiştir. Gliserol konsantrasyonu, çözelti sıcaklığı ve pH?nın film mekanik özelliklerine etkisinin araştırılması amacıyla, bu parametreler kullanılarak yanıt yüzey yöntemi ile deneme tasarımları oluşturulmuş, film üretimi gerçekleştirilmiş ve optimum film karakteristiklerine sahip film üretiminin sağlandığı parametreler belirlenmiştir. Optimum koşullarda amiloz-lipit kompleksi kullanılarak üretilen filmlerin gerilme dirençleri miristik (1,09 MPa) ve stearik asit (3,360 MPa) için kontrol filme göre daha yüksek, uzama değeri ise kaprik asit (%114,59) için daha yüksek bulunmuştur. Amiloz-lipit kompleksi kullanılarak üretilen filmlerin çözünürlük, nem ve kalınlık değerleri kontrollere göre daha yüksek bulunmuştur. En iyi su buharı bariyer özelliğine amiloz-miristik asit kompleks filmi (0,394 g.mm/m2.h.kPa) ile elde edilmiştir. SEM ve AFM görüntüleri amiloz-lipit kompleksi kullanımının film morfolojik ve topografik özelliklerine etki ettiğini göstermiştir. Su ile yüzey temas açısı sonuçlarına göre sadece amiloz-stearik asit kompleksi filmi hidrofobik yüzeye sahip olmuşlardır. Tüm sonuçlar genel olarak değerlendirildiğinde proje kapsamında karabuğday nişastasından enzime dirençli nişasta kaynağı olma potansiyeline sahip amiloz-lipit kompleksi oluşturmuş; oluşturulan bu komplekslerden mekanik özellikleri yüksek yenilebilir film üretimi gerçekleştirilebilmiştir.Article Development and Characterization of Starch-Fatty Acid Complexes Produced with Buckwheat Starch and Capric/Stearic Acid Using Different Reaction Conditions(Elsevier, 2025) Oskaybas-Emlek, Betul; Ozbey, Ayse; Aydemir, Levent Yurdaer; Kahraman, KevserThe aim of present study was to investigate the impact of reaction parameters on the complex formation between buckwheat starch and capric acid (B-Capric) or stearic acid (B-Stearic). The most effective parameters on complex formation indicator (Complex index (CI) value) were found as reaction temperature (60-90 degrees C) and pH (5-8). Additionally, the effect of these parameters on physicochemical, pasting, and in-vitro digestibility properties of complex samples were evaluated. XRD and FTIR was also used in characterize the complex samples. In general, increasing pH increased the CI values of B-Stearic samples while decreasing those of B-Capric samples. Syneresis of buckwheat starch increased after complexation while paste clarity and swelling power diminished. The pasting properties of native starch significantly changed after complex formation. The FTIR results showed that starch structure changed with complex formation. XRD revealed that buckwheat starch, having an A-type pattern, converted to V-type pattern after complexation. Complex formation of buckwheat starch with capric and stearic acid significantly increased the RS content of buckwheat starch (19.01 %) by up to 36.25 % and 30.60 %, respectively. These results highlight the possibility of using buckwheat starch-capric acid/stearic acid complexes in food formulation to enhance the RS content.Article Citation - WoS: 4Citation - Scopus: 4Development of Buckwheat Starch-Capric Acid Complex-Based Film: Process Optimization and Film Characterization(Wiley-VCH Verlag GmbH, 2025) Koca, Esra; Kahraman, Kevser; Oskaybas-Emlek, Betul; Ozbey, Ayse; Aydemir, Levent YurdaerTo overcome the limitations of starch usage alone, the film formation ability of the buckwheat starch-capric acid complex (BS-CA) was optimized, and the films were characterized. Significant models were obtained for tensile strength (TS) and Young's modulus (YM) of BS-CA film (p < 0.0001). The glycerol/starch ratio, temperature, and their interactions were significant in the YM model (R-2 is 0.9851). The BS-CA film had a better water vapor barrier (0.463 +/- 0.02 g mm/m(2) h kPa), with lower water solubility (WS) (34.18 +/- 1.70%) and moisture content (MC) (16.87 +/- 0.09%) than the buckwheat starch (BS) film (p < 0.05). It had lower thickness (0.073 +/- 0.00 mm) and TS (0.624 +/- 0.04 MPa) but higher elasticity (114.60 +/- 3.12%). The non-covalent interactions were determined between BS and CA, since new peaks were not observed in the film's FTIR spectrum. BS-CA film had a typical V-type crystalline structure and had slightly lower decomposition temperatures than the BS film. Contact angle measurements (55.19 degrees +/- 1.7), and images of AFM topography and SEM showed that the BS-CA film surface was hydrophilic; height and average roughness values were 1014 and 276 nm, respectively, which were quite higher than those of BS film. The results reveal that starch modification with fatty acid is a promising way to develop starch-based films to be used in practical applications.Article Citation - WoS: 19Citation - Scopus: 27Production of Buckwheat Starch-Myristic Acid Complexes and Effect of Reaction Conditions on the Physicochemical Properties, X-Ray Pattern and FT-IR Spectra(Elsevier, 2022) Oskaybas-Emlek, Betul; Ozbey, Ayse; Aydemir, Levent Yurdaer; Kahraman, KevserIn this study, the effect of reaction parameters on complex index (CI%) value of complexes formed between buckwheat starch (BS) and myristic acid (MA) was investigated. The temperature (60-90 ?C) and MA to BS ratio (0.1-0.8 mmoL/g) were determined as the most effective parameters and their effect on CI% was evaluated using response surface methodology. The MA to BS ratio, temperature, and interaction between them had an influence on CI%. The CI% of BS-MA complexes increased with increasing MA ratio until a certain level of MA. Principal component analysis (PCA) was used for correlation analysis between parameters. Swelling power and paste clarity of BS decreased with complex formation while syneresis increased. Peak and final viscosity values of the BS-MA complexes were significantly lower than those of BS. FT-IR revealed the complex formation led to change in starch structure. The XRD confirmed the BS-MA complex formation but the BS-MA produced using 0.1 mmoL/ g at 60 ?C was not detected by XRD due to having low crystallinity, and expectedly, the lowest relative crystallinity value was achieved with this sample among complex samples. All results showed that the buckwheat be an alternative starch source for starch formation.Article Citation - WoS: 13Citation - Scopus: 9An Empirical Study of Sentiment Analysis Utilizing Machine Learning and Deep Learning Algorithms(Springernature, 2024) Erkantarci, Betul; Bakal, GokhanAmong text-mining studies, one of the most studied topics is the text classification task applied in various domains, including medicine, social media, and academia. As a sub-problem in text classification, sentiment analysis has been widely investigated to classify often opinion-based textual elements. Specifically, user reviews and experiential feedback for products or services have been employed as fundamental data sources for sentiment analysis efforts. As a result of rapidly emerging technological advancements, social media platforms such as Twitter, Facebook, and Reddit, have become central opinion-sharing mediums since the early 2000s. In this sense, we build various machine-learning models to solve the sentiment analysis problem on the Reddit comments dataset in this work. The experimental models we constructed achieve F1 scores within intervals of 73-76%. Consequently, we present comparative performance scores obtained by traditional machine learning and deep learning models and discuss the results.Book Part Ionizing Radiation(CRC Press, 2024) Braşoveanu, Mirela M.; Emlek, Betul Oskaybaş; Sabbaghi, Hassan; Kahraman, Kevser; Muti, Serpil Ozturk; Sher, Farooq; Nemţanu, Monica R.Ionizing radiation processing has demonstrated the potential to bring significant transformations in both the structure and functioning of starch. These modifications cover crucial features, including granular and molecular characteristics, pasting properties, rheological attributes, and gelatinization behavior. This comprehensive chapter aims mainly to provide a consolidated overview of the key findings that have been made recently about major alterations in the fundamental attributes of starch generated by diverse plant sources when exposed to ionizing radiation processing. Beyond articulating these modifications, the chapter explores other relevant topics, including analytical methods employed for characterizing irradiated starch, clarification of the radiation-induced reaction mechanism, and a discussion on safety considerations and regulatory frameworks associated with the utilization of ionizing radiation for treating starch within the context of food-related applications. Furthermore, based on all the highlighted elements, future research directions are proposed, with a focus on characterizing and defining the internal structure of irradiated starch, as well as exploring the functionalities of radiation-modified starches in both innovative and traditional food formulations. © 2024 Elsevier B.V., All rights reserved.Article Citation - WoS: 32Citation - Scopus: 43Enhancing Cybersecurity in Smart Grids: False Data Injection and Its Mitigation(MDPI, 2021) Unsal, Derya Betul; Ustun, Taha Selim; Hussain, S.
