Conference Object Embryo Spatial Model Reconstruction(Springer international Publishing Ag, 2020) Dirvanauskas, Darius; Maskeliunas, Rytis; Raudonis, Vidas; Misra, SanjayTime lapse microscopy offered new solutions to study embryo development process. It allows embryologist to monitor embryo growth in real time and evaluate them without interfering into their growth environment. Embryo evaluation during growth process is one of the key criteria in embryo selection for fertilization. Live embryo monitoring is time consuming and new tools are offered to automate part of process. Our proposed algorithm gives new possibilities for embryo monitoring. It uses embryo images which are taken from different embryo layers, extracts embryo cell features and returns metrical evaluation to compare different embryos. High number of extracted features shows embryo fragmentation. Other tool whichwe present is spatial embryo model. Features extracted from embryo layers are combined together to spatial model. It allows embryologist to examine embryo model and compare different layers in one space. The obtained spatial embryo model will be later used to develop new algorithms for embryo analysis tasks.Master Thesis Kentsel dönüşüm kapsamında ankara'da riskli bulunan binaların yorumlanması(2020) Çamurdan, Asil Tuğana; Mertol, Halit CenanTürkiye'de bulunan birçok yapı deprem bölgelerinde yer almaktadır. Özellikle 1999 Adapazarı Depremi öncesinde yapılmış olan yapıların deprem yükleri altında göçme riski bulunmaktadır. Bu depremden sonra gerçekleştirilen malzeme, analiz, tasarım, yapım ve denetim ile ilgili düzenlemeler, daha güvenli yapıların tasarlanıp inşa edilmesine yol açmıştır. Türkiye'de daha öncesinde yapılan bütün eski yapıların durumunun, yapıların güçlendirme veya yıkım ve yapım işlemi gerektirip gerektirmediğinin 'Kentsel Dönüşüm' adı altında değerlendirilmesi ihtiyacı doğmuştur. Bu çalışmada, Kentsel Dönüşüm yapılan binaların yapısal değerlendirilmesi ile ilgili çalışmalar incelenmiştir. Ankara'daki binalar için hazırlanan 39 adet yapısal değerlendirme raporu tetkik edilmiş ve sonuçları beton dayanımı, zemin taşıma kapasitesi, deprem yükleri, riskli kolon sayıları ve onların taşıdığı kesme kuvvetleri, vb. konularda karşılaştırmalar yapılmıştır. Binaların neden riskli olduğu hakkında grafikler çizilmiştir. Bu karşılaştırmalar ve grafikler ışığında bazı ilişkiler oluşturulmuştur. Bu çalışmanın sonuçları genellenerek Türkiye'nin diğer illerine gerçekleştirilecek kentsel dönüşüm çalışmalarında kullanılabilir.Master Thesis Serbest Biçimli Çelık Çift Katmanlı Uzay Kafeslerin Optimizasyonu ve Standardizasyonu(2021) Shaban, Samer S S; Azad, Saeıd KazemzadehSon yıllarda düzensiz eğrili ancak estetik açıdan hoş görünen konfigürasyonlara sahip serbest biçimli yapıların kullanımına artan bir ilgi olmuştur. Normal çelik uzay kafeslerin tasarım optimizasyonu, yapısal optimizasyon literatüründe detaylı bir şekilde ele alınsa da, gerçek boyutlu serbest biçimli uzay kafes yapıların optimum tasarımında yapılan çalışmalar hala sınırlı düzeyde kalmıştır. Bir yandan, gerçek boyutlu serbest biçimli çelik kafeslerin optimizasyonunun önündeki ana engel, güncel evrimsel optimizasyon algoritmalarıyla ortaya çıkan aşırı hesaplama yüküdür. Öte yandan, algoritma tarafından nihai tasarımda farklı çelik kesit boyutlarının sayıca fazlalığını önlemek için gerekli kısıtlamalar uygulanmamışsa, geleneksel optimizasyon algoritmaları kullanılarak elde edilen nihai tasarımların uygulamada tercih edilmemesi muhtemeldir. Bu nedenle, tek bir optimum veya optimuma yakın tasarım sunmak yerine, tasarımcıya veya karar vericiye, hem minimum ağırlığı hem de mevcut ürün çeşitliliğini hesaba katan ve etkin tasarım alternatifleri setinden oluşan bir Pareto eğrisi sunmak daha arzu edilir olacaktır. Buna göre, bu çalışmada, gerçek boyutlu serbest biçimli çelik çift katmanlı uzay kafeslerin optimizasyonu ve standardizasyonu için hesaplama açısından verimli çok aşamalı rehberli stokastik arama algoritması önerilmiştir. İlk optimizasyon aşamasında, algoritmaya ticari olarak mevcut çelik profillerin eksiksiz bir setinin sunulduğu ve sonraki aşamalarda, kullanılmayan veya daha az kullanılan kesitleri eleyerek kesit listesinin kademeli olarak küçültüldüğü, bir tasarım odaklı kesit eleme yaklaşımı izlenmiştir. Serbest biçimli çelik çift katmanlı uzay kafeslerin sıra dışı kolay olmayan test örnekleri üzerinde önerilen tekniğin kullanışlılığını göstermek için algoritmanın iki farklı versiyonu kullanılmış ve elde edilen Pareto eğrisi, minimum ağırlık ve çelik kesit çeşitleri arasındaki dengeyi göstermek için çizilmiştir.Article Citation - WoS: 5Citation - Scopus: 5Physical Characterization of Thermally Evaporated Sn-Sb Thin Films for Solar Cell Applications(Springer Heidelberg, 2023) Bektas, Tunc; Surucu, Ozge; Terlemezoglu, Makbule; Parlak, MehmetThe substitution of Sb in binary SnSe structure may lead to tailoring the physical properties of both SnSe and SbSe, promising absorber layers for thin film solar cells. The resulting Sn-Sb-Se structure could be an outstanding material for photovoltaic applications. In this study, Sn-Sb-Se thin films were deposited by thermal evaporation, and the effect of annealing on the films' structural, optical, and electrical properties were reported. XRD measurement shows that annealing at 300 degrees C yields the best crystalline quality, and structural parameters were calculated using XRD data. SEM and AFM measurements indicate deformation in the film surface after annealing at 400 degrees C. UV-Vis spectroscopy measurement provides a high absorption coefficient which indicates a direct band gap. The band gap and activation energies of the as-grown sample were found as 1.59 eV and 106.1 meV, respectively. The results of SEM, AFM, XRD, Raman, UV-Vis spectroscopy and temperature-dependent photoconductivity measurements were discussed throughout the paper.Book Part Citation - Scopus: 2Novel Covid-19 Recognition Framework Based on Conic Functions Classifier(Springer Science and Business Media Deutschland GmbH, 2022) Karim,A.M.; Mishra,A.The new coronavirus has been declared as a global emergency. The first case was officially declared in Wuhan, China, during the end of 2019. Since then, the virus has spread to nearly every continent, and case numbers continue to rise. The scientists and engineers immediately responded to the virus and presented techniques, devices and treatment approaches to fight back and eliminate the virus. Machine learning is a popular scientific tool and is applied to several medical image recognition problems, involving tumour recognition, cancer detection, organ transplantation and COVID-19 diagnosis. It is proved that machine learning presents robust, fast and accurate results in various medical image recognition problems. Generally, machine learning-based frameworks consist of two stages: feature extraction and classification. In the feature extraction, overwhelmingly unsupervised learning techniques are applied to reduce the input data’s size. This step extracts appropriate features by reducing the computational time and increasing the performance of the classifiers. A classifier is the second step that aims to categorise the input. Within the proposed step, the unsupervised part relies on the feature extraction by using local binary patterns (LBP), followed by feature selection relying on factor analysis technique. The LBP is a kind of visual descriptor, mainly applied for image recognition problem. The aim of using LBP is to analyse the input COVID-19 image and extract salient features. Furthermore, factor analysis is a statistical technique applied to define variability among observed variables in less unnoticed variables named factors. The factor analysis applied to the LBP wavelet aims to select sensitive features from input data (LBP output) and reduce the size input. In the last stage, conic functions classifier is applied to classify two sets of data, categorising the extracted features by using LBP and factor analysis as positive or negative COVID-19 cases. The proposed solution aims to diagnose COVID-19 by using LBP and factor analysis, based on conic functions classifier. The conic functions classifier presents remarkable results compared with these popular classifiers and state-of-the-art studies presented in the literature. © 2022, Springer Nature Switzerland AG.Conference Object Evaluation of the Individualized Rehabilitation Program (happy Treatment Protocol) in Children With Nocturnal Enuresis(Springer London Ltd, 2023) Ozturk, A.; Sonmezer, E.; Dayanc, M.Article Citation - Scopus: 1Anxiety and Depression After Cesarean: Non-Pharmacological Evidence Based Practices;(Dokuz Eylul University, 2022) Terzioğlu,F.; Gençbaş,D.; Boztepe,H.; Doğu,N.; Akdeniz,C.; Yüceer,B.The purpose of this review is to examine the non-pharmacological evidence-based practices of anxiety and depression after a cesarean section delivery. Postpartum anxiety and depression have increased in the last decade, the rates of postpartum depression are around 13% worldwide. In the postpartum period, women may experience anxiety and depression due to the operation they have undergone; such as being in an unfamiliar environment, facing new technological equipment and encounters with the medical teams, the post-operative pain, the new roles women undertake as mothers. One of the factors that increase anxiety and depression in the postpartum period is the type of delivery. In Turkey, the rate of cesarean delivery is comparatively high, which is approximately 52%. Anxiety and depression after cesarean section develop due to fear and concern such as the complications that may occur during and after the mother's anesthesia, the possibility delaying breastfeeding her baby, and experiencing pain. Non-pharmacological evidence-based applications such as reiki, acupressure, hand and foot massage, yoga, reflexology, aromatherapy, skin to skin care, nursing care protocols were found to be effective in studies conducted to reduce anxiety and depression after cesarean-section. Nurses who have critical roles and responsibilities in pre-and post-cesarean care practices are recommended to include these evidence-based non-pharmacological practices in routine care practices. © 2022, Dokuz Eylul University.

MATERIAL and METHODS: A total of 295 patients with Grade 1 residual Meningiomas (197 women, 98 men), who were treated by adjuvant radiosurgery in Gazi University Gamma Knife Center between 2004-2015 were analyzed. WHO Grade 2 and 3 meningiomas were not included in our study. Minimum radiological follow-up was 24 months. The median follow-up was 54 months. The tumor volume, location, treatment dose, morbidity, progression free survival and tumor control rate were analyzed. RESULTS: The median tumor volume was 5.2 cm(3) (0.04-39.7), median age was 50 (20-80), median dose was 14 Gy and tumor control rate was 94.5% (stationary in 85.0%, volume reduction in 9.5%). Increase in tumor volume was seen in 16 patients (5.5%) and re-operation was performed in 5 of them (1.6%). Stereotactic radiosurgery was performed again for 8 patients (2.7%).The location of the tumors was as follows: 39.3% parasellar region, 20% cerebellopontine angle, 13.6% petroclival and 27.1% was parasagittal, falcine or convexity. Major morbidities were detected in 6 (2%) patients. Minor morbidities were detected in 18 (6.1%) patients. CONCLUSION: Stereotactic radiosurgery is an effective and safe treatment modality for residual Grade I meningiomas.Article İdeal Diyalogtan Sivil Diyaloğa Dönüşüm üzerine Kavramsal İzdüşüm: Tarihsel bir İnceleme(2021) Seyidov, IlgarDialogue is one of the basic concepts of communication. As the understanding of two-way communication and mutual relations has become important by 2000s, dialogue has also started to be re-embraced within different fields of social sciences. Although it is known as a communication between two individuals, it includes very sophisticated context. The quality of communication is the main point in dialogic communication. Although this concept has been widely used in different research fields such as culture, political communication, religion, sociology and international relations studies, it has not been conceptualized with all aspects. It still lacks of proper conceptualization and profound research. In this vein, the current study aims to explore the historical and conceptual background of dialogue. Based on comprehensive literature review, first, the conceptualization of “ideal” dialogue will be discussed within various philosophical and sociological perspectives. In doing so, the historical context will be taken into account. Then, “civil” dialogue will be examined within the framework of dialogue. It will be focused on its contextual and structural transformation under specific characteristics. In the conclusion, the study will discuss how and why civil society is appropriate to formation of dialogue.Article Citation - Scopus: 1Stenotic Double-Orifice Mitral Valve After Surgical Repaired Partial Atrioventricular Septal Defect(Wiley, 2020) Duran Karaduman, Bilge; Torun, Ayse Nur; Ayhan, Huseyin; Keles, Telat; Bozkurt, EnginDouble-orifice mitral valve (DOMV) is an uncommon congenital anomaly account for 1% of congenital heart disease. However, accurate diagnosis and evaluation of valve stenosis or regurgitation and other concomitant congenital anomalies due to DOMV are required to obtain suitable treatment. Two- and three-dimensional echocardiography can contribute valuable functional and anatomic information that can support to reach this goal. Here, we present a case of complete bridge-type DOMV that causes mitral stenosis after surgical repair of the partial atrioventricular septal defect in childhood.
