    A study on effective data preprocessing and augmentation method in diabetic retinopathy classification using pre-trained deep learning approaches

    İncir, Ramazan; Bozkurt, Ferhat

    High glucose levels in the blood not only damage different tissues and organs of the body, but also cause adverse effects on the eye. This condition is called diabetic retinopathy (DR). DR can cause blurred vision, darkening of the field of vision, and severe vision loss. The number of people infected with the disease is increasing in our country and worldwide. The time-consuming physician check-ups and the presence of small lesions indicate the need to develop diagnostic systems. Deep learning-based applications have become the trend for diagnosing and grading diseases from images. This study aims to create a meaningful and sufficient dataset using effective data preprocessing and affine transformation techniques in diabetic retinopathy classification. In this study, classification was performed using seven different pre-trained deep learning architectures. An experimental study of each technique was performed on the EyePACS dataset. An overfitting problem was encountered in the experimental results with the original data set. Thus, data preprocessing and data augmentation processes were carried out in order to eliminate overfitting by considering the imbalance between classes in the dataset. The classification performance obtained from each architecture was observed according to performance metrics of precision, recall, F1 Score, accuracy, and loss. In this study, the best performance was achieved with 97.65% test accuracy with the proposed EfficientNetV2-M network model.

    Innovations in dairy technology: probiotics in Turkish white cheese production

    Mazlum, Halit; Atasever, Mustafa

    Cheese offers significant advantages as a probiotic carrier food compared to fermented milk and yoğurt due to its fat content, solid matrix, higher pH, low oxygen levels, and longer shelf life. This study examined Turkish white cheeses ripened with both classical starter culture (Lactococcus lactis subsp. lactis and Lactococcus lactis subsp. cremoris) and various probiotic cultures (Lactobacillus acidophilus, Lactobacillus casei, Lactobacillus paracasei, and Bifidobacterium bifidum). The quality and functional properties of these cheeses were investigated to evaluate the effect of adding probiotics to traditional starter culture and their potential for use as carrier food for probiotics. During the 90-days ripening period, the numbers of L. acidophilus, L. casei, L. paracasei, and B. bifidum were determined to be in the range of 8.09 ± 0.34–8.65 ± 0.30, 7.19 ± 0.28–8.12 ± 0.90, 7.01 ± 1.45–8.73 ± 0.98, and 7.16 ± 1.10–8.21 ± 1.19 log cfu/g, respectively. The study found that probiotic levels in the cheese remained above the effective threshold (≥ 107 cfu/g) throughout the ripening process. This was accompanied by an increase in water-soluble nitrogen, an indicator of proteolysis, leading to higher ripening index values in all cheese samples. In terms of sensory evaluation, cheeses with L. acidophilus and L. paracasei were particularly well-received, scoring higher (7.90 ± 0.30–8.47 ± 0.12, 7.80 ± 0.34–8.75 ± 0.12, respectively) in taste and aroma than the others. Overall, probiotics positively influenced the quality and functional properties of the white cheese. Notably, the L. casei ATCC 393 strain, used for the first time in Turkish white cheese production, proved highly compatible with existing production technologies. It was concluded from the study that Turkish white cheese is a suitable food for transporting probiotics to the intestinal environment.

    Different gait combinations based on multi-modal deep CNN architectures

    Yaprak, Büşranur; Gedikli, Eyüp

    Gait recognition is the process of identifying a person from a distance based on their walking patterns. However, the recognition rate drops significantly under cross-view angle and appearance-based variations. In this study, the effectiveness of the most well-known gait representations in solving this problem is investigated based on deep learning. For this purpose, a comprehensive performance evaluation is performed by combining different modalities, including silhouettes, optical flows, and concatenated image of the Gait Energy Image (GEI) head and leg region, with GEI itself. This evaluation is carried out across different multimodal deep convolutional neural network (CNN) architectures, namely fine-tuned EfficientNet-B0, MobileNet-V1, and ConvNeXt-base models. These models are trained separately on GEIs, silhouettes, optical flows, and concatenated image of GEI head and leg regions, and then extracted GEI features are fused in pairs with other extracted modality features to find the most effective gait combination. Experimental results on the two different datasets CASIA-B and Outdoor-Gait show that the concatenated image of GEI head and leg regions significantly increased the recognition rate of the networks compared to other modalities. Moreover, this modality demonstrates greater robustness under varied carrying (BG) and clothing (CL) conditions compared to optical flows (OF) and silhouettes (SF).

    Dual Capacitive Behavior of Hollow Porous Gold Nanoparticle/Multi-Walled Carbon Nanotube Composite Films as Anode and Cathode Electrode Materials for Supercapacitors

    Bahar, Necmiye; Ekinci, Duygu

    In this paper, composites of multi-walled carbon nanotubes decorated with hollow porous gold nanoparticles (HPAuNPs/MWCNTs) were prepared using wet chemistry methods, and their capacitive properties were evaluated in Na2SO4 aqueous solution on glassy carbon (GC) electrodes as both cathode and anode materials by cyclic voltammetry (CV), galvanostatic charge–discharge (GCD), and electrochemical impedance spectroscopy (EIS) techniques. Also, the MWCNTs were studied under similar experimental conditions for comparison. The results revealed that the charge storage mechanisms of the MWCNTs/GC and HPAuNPs/MWCNTs/GC electrodes were electrostatic in the negative potential window, whereas they exhibited pseudocapacitive energy storage behavior in the positive potential region. Moreover, the HPAuNPs/MWCNTs/GC electrode yielded specific capacitance values of 57 and 49 F g−1 at a scan rate of 20 mV s−1 in the cathodic and anodic potential windows, respectively, which were higher than those of the MWCNTs/GC electrode (~9 F g−1).

    Perspectives on the mental health of immigrant children in the pediatric emergency department: a phenomenological study

    Uzun, Sevda; Ustuner Top, Fadime

    The concept of immigration is a complex phenomenon that goes far beyond mere relocation and refers to the transition from one social environment to another or from one culture to another. Immigration and its effects on children are regarded as global and interdisciplinary problems. This study aims to reveal the opinions of nurses working in the pediatric emergency department about the mental health of immigrant children. In this qualitative research, a phenomenological research design was used (N = 19).Interviews were conducted using a semi-structured interview form. Colaizzi’s method was used to analyze the data manually. Four categories, eleven themes, and thirty-eight sub-themes emerged from the analysis of the data. The difficulties nurses experience with immigrant children and their relatives in providing care include communication problems, cultural problems, and economic problems. The causes of mental health problems in immigrant children include war, exposure to immigration traumas, cultural assimilation problems, loss/absence of parents, economic reasons/excessive role overload, and exposure to neglect and/or abuse. Education, economic aid, communication, non-stigmatization, and social support were identified as significant sub-themes for practices to protect/promote children’s mental health. The study showed that immigrant children experience physical and mental problems. Nurses struggle to treat immigrant children effectively but have difficulties due to insufficient facilities. It may be suggested to include cultural care models in patient care.

    The Effect of Surface Roughness on Fatigue Life in AZ31 Magnesium Alloy

    Karabudak, Filiz; Şüküroğlu, Ebru Emine; Şüküroğlu, Süleyman; Yeşildal, Ruhi

    Magnesium alloys have excellent properties such as high specific strength, rigidity, good damping, electromagnetic shielding, castability, and machinability. However, corrosion, creep, and fatigue resistance are generally the properties that need to be improved. In this study, a hybrid coating was formed on AZ31 magnesium alloy with different surface roughness at different frequencies. In the hybrid coating, an oxide coating was first grown on the surface by the micro-arc oxidation method, and then, the epoxy coating was grown on this oxide coating by the dipping method. The characterization of the coatings was performed by XRD, SEM, and EDS analysis. Furthermore, the relationship between fatigue life and surface roughness was also discussed in this study. The fatigue life and strength of the coated samples were determined as a result of the tests performed on the fatigue device. It was concluded that the fatigue life and strength of hybrid coatings were much better compared to uncoated and single-layer coated samples.

    Effect of Isothermal Treatment on Mechanical and Tribological Properties of Alloy Zn – 40% Al – 2% Cu – 2% Si

    Savaşkan, Temel; Hekimoğlu, Ali Paşa; Azaklı, Zeki

    The effect of isothermal exposure at temperatures from 100°C to 250°C for 8 hours on the structure, mechanical and tribological properties of the Zn – 40% Al – 2% Cu – 2% Si alloy produced by chill casting is studied. The isothermal treatment eliminates dendritic segregation yielding a coarse-grained polyhedral structure containing an α-solid solution with fine inclusions of silicon and zinc-rich phase. Increase in the temperature of the isothermal exposure leads to decrease in the hardness and strength and increase in the ductility, in the coefficient of friction and in the wear magnitude while reducing the average roughness of the alloy surface.

    Geographic distribution of two Montivipera taxa using ecological niche modeling

    Kurnaz, Muammer

    Ecological niche modeling predicts the potential distribution areas of species and contributes to measuring the niche differentiation among taxa. Montivipera albizona and M. bulgardaghica are two mountain viper taxa distributed in Anatolia. In the present study, the habitat suitability of M. albizona and M. bulgardaghica was assessed, and ecological niche ranges between these taxa were compared. According to species distribution models, while the distribution area of M. albizona covers a relatively large region in central Anatolia, M. bulgardaghica has a relatively narrow distribution over the eastern Taurus mountains. The species distributional results showed that the annual temperature range and mean temperature of the coldest quarter were the highest contributing variables, with 62.5% for M. albizona and 67.9% for M. bulgardaghica. Montiverpa albizona prefers 13 different habitat types, while M. bulgardaghica prefers 6 different habitat types in their distribution areas. Niche differentiation analysis revealed that there was no overlap between the two taxa in terms of their ecological niches.

    Başoğlu, Mehmet; Çakir, Bakiye; Duman, Şeyda; Aydiner, Alev

    The Y3Ba5Cu8O18 (Y358) superconductors were produced using the Melt-Powder-Melt-Growth (MPMG) method. In the crystal growth process, Y2O3 powder was used as a substrate in both powder and tablet form. The first sample was produced without using any buffer layer, the second sample was produced with a powdered Y2O3 buffer layer, and the third sample was produced with a tablet-form Y2O3 buffer layer. The effect of the Y2O3 substrate on the structural and physical properties of the Y358 superconductor samples was investigated. Superconducting phases were observed in all samples of Y358 through XRD measurements, confirming their presence. Samples fabricated using the powder and tablet forms of the Y2O3 substrate had a better microstructure than the sample fabricated without a Y2O3 substrate. The highest critical current density (J c) value was obtained at 77 K for the Y358 sample produced with a Y2O3 powder substrate, and the J c value was calculated as 1.2 × 104 A cm–2 according to the Bean model.

    Saeighi Mameghani, Shiva; Yilmaz, Müge; Balcı Çelik, Seher; Karimi, Kambiz

    Right now, more than ever in our lives, we need to remain optimistic. The present study aimed to examine the validity and reliability of The Optimism Scale, developed by Balcı & Yılmaz (2002), among Iranian university students and to adapt to Iranian culture. The scale is a single-factor scale with 24 items. The participants were selected using an appropriate sampling method, and the sample consisted of 600 Iranian university students (360 females and 240 males) from Tehran and Tabriz cities. Participants’ age ranged from 18 to 24 years (M = 21.58, SD = 1.75). The study findings suggested similarities between Iran and Turkey culture (e.g., religion, language, neighborhood relations). The optimism scale revealed a good construct validity in the Goodness of fit index indicators. The Cronbach alpha internal consistency coefficient for the scale was 0.76 and Convergent validity with happiness was 0.38. In future studies, the scale’s factor structure can be investigated in different samples, such as adolescents and adults.

    Effect of Plastic Deformation on the Mechanical Properties of Dual-Phase Steels Using Nanoindentation

    Ekmekci, Dursun; Uşun, Altuğ; Cora, Ömer Necati

    The mechanical properties of two advanced high-strength steels (AHSS), DP 1000 and DP 1200 dual-phase (DP) grades, under deformed and undeformed conditions, were investigated using nanoindentation, and the results were compared with those obtained from the conventional methods. To this goal, 3-point bending tests were applied to induce deformation in the samples. Before and after these tests, nanoindentations were performed at different forces and indentation depths. In addition to the hardness and modulus of elasticity values of the steels, the residual stresses on the samples after deformation were obtained by using the equations suggested in the literature, also with x-ray diffraction (XRD). Finite element (FE) modeling of 3-point bending and nanoindentation were performed to obtain stress–strain curves of the materials numerically. The stress–strain curves obtained by numerical analysis agree well with those reported in the literature. The variations of the hardness and modulus of elasticity values are narrower for deeper indentation (50 nm versus 200 nm), and the effect of deformation is more pronounced on the modulus of elasticity values (10–30% increase with the deformation) while hardness values increased with the effect of deformation, 10% at most.

    Examining the role of urban-industrial symbiosis in the circular economy: an approach based on N-Force field theory of change and N-ISM-Micmac

    Erol, Ismail; Peker, Iskender; Ar, Ilker Murat; Searcy, Cory

    The circular economy (CE) refers to a new industrial paradigm that contrasts with the linear supply chain structure based on a "take, make, use, dispose" pathway. Due to its potential contributions to improving the CE, industrial symbiosis (IS) has been recognized as a feasible way to advance it. Urban symbiosis is an extension of IS that involves a series of symbiotic relationships among enterprises within the urban area. Combining urban and industrial symbiosis (Ur-IS) is a step toward better resource efficiency in urban areas and industrial zones and urban areas. However, while there are several driving forces for Ur-IS adoption, there are also many inhibiting factors. A comprehensive decision framework is needed to address the principal drivers and challenges for Ur-IS initiatives. Türkiye, designated as a candidate for full EU membership in 1999, also places importance on environmental sustainability goals and effective resource management in its own move towards a CE. Our literature review concluded that there is only one quantitative study investigating the driving and (or) restraining forces for Ur-IS adoption in emerging and industrialized countries. The main purpose of this study is to investigate the potential of Ur-IS implementation in Türkiye through the proposed Neutrosphopic-Simple Additive Weighting Method-based force field theory of change and the Neutrosphopic–Interpretive Structured Modeling-Cross-Impact Matrix Multiplication Method. The findings suggest that lack of policies, lack of incentives and regulations, and vulnerability and supply uncertainty are the most significant restraining forces for Ur-IS implementation in Türkiye. The research findings can assist decision-makers in Türkiye in effectively implementing Ur-IS.

    The effect of fabrication method on physical properties of different Y211 and 20% Ag2O added YBCO sample

    Duman, Şeyda; Çakır, Bakiye; Başoğlu, Mehmet; Küçükömeroğlu, Tayfur; Aydıner, Alev

    In this study, it is aimed to investigate the effects of production methods on the physical properties of 20% Ag2O and different ratios of Y211 added YBCO samples. In this context, the samples with Y123 + x % (x = 20, 25, 30) Y211 + 20%Ag2O compositions were fabricated by MPMG and TSMG methods in two groups to join YBCO main samples. XRD measurements were performed to determine the characteristic peaks. Trapped magnetic fields and vertical levitation forces between the bulk samples and a permanent magnet were measured using a computer-controlled system in ZFC at 77 K. From the XRD measurements, it was found that MPMG YBCO samples had a dominant superconducting structure and partially showed orientation peaks in the c-axis direction, while TSMG YBCO samples were single-crystal samples oriented along the c-axis. From the trapped magnetic field measurement results, the trapped magnetic field value of the Y123 + 25%Y211 + 20%Ag2O (TAg25) sample prepared by the TSMG method was higher than that of the other samples. Among the levitation force measurement results, the maximum repulsive force values of TAg25 and TAg30 (Y123 + 30%Y211 + 20%Ag2O) samples are the highest. At the same time, the hysteresis widths of these samples are also the highest, which proves that their flux-pinning potential is higher than that of the other samples.

    MediNet: transfer learning approach with MediNet medical visual database

    Reis, Hatice Catal; Turk, Veysel; Khoshelham, Kourosh; Kaya, Serhat

    The rapid development of machine learning has increased interest in the use of deep learning methods in medical research. Deep learning in the medical field is used in disease detection and classification problems in the clinical decision-making process. Large amounts of labeled datasets are often required to train deep neural networks; however, in the medical field, the lack of a sufficient number of images in datasets and the difficulties encountered during data collection are among the main problems. In this study, we propose MediNet, a new 10-class visual dataset consisting of Rontgen (X-ray), Computed Tomography (CT), Magnetic Resonance Imaging (MRI), Ultrasound, and Histopathological images such as calcaneal normal, calcaneal tumor, colon benign colon adenocarcinoma, brain normal, brain tumor, breast benign, breast malignant, chest normal, chest pneumonia. AlexNet, VGG19-BN, Inception V3, DenseNet 121, ResNet 101, EfficientNet B0, Nested-LSTM + CNN, and proposed RdiNet deep learning algorithms are used in the transfer learning for pre-training and classification application. Transfer learning aims to apply previously learned knowledge in a new task. Seven algorithms were trained with the MediNet dataset, and the models obtained from these algorithms, namely feature vectors, were recorded. Pre-training models were used for classification studies on chest X-ray images, diabetic retinopathy, and Covid-19 datasets with the transfer learning technique. In performance measurement, an accuracy of 94.84% was obtained in the traditional classification study for the InceptionV3 model in the classification study performed on the Chest X-Ray Images dataset, and the accuracy was increased 98.71% after the transfer learning technique was applied. In the Covid-19 dataset, the classification success of the DenseNet121 model before pre-trained was 88%, while the performance after the transfer application with MediNet was 92%. In the Diabetic retinopathy dataset, the classification success of the Nested-LSTM + CNN model before pre-trained was 79.35%, while the classification success was 81.52% after the transfer application with MediNet. The comparison of results obtained from experimental studies observed that the proposed method produced more successful results. Graphical abstract: [Figure not available: see fulltext.]

    Yazıcı Çelebi, Gülin; Kaya, Feridun

    This study was conducted to examine the association of various personal, affective, and cognitive factors with suicide risk. The study group consisted of a total of 423 individuals, including 341 (74%) females and 82 (26%) males, who lived in Turkey and declared that they were Muslims. The data of the study, in which a cross-sectional design was employed, were collected between October and December 2022. The mean age of the participants was 26.84 years (SD = 9.88, min–max = 18–64). The data collection measures included the Psychological Distress Scale, the Perception of God Scale, the Two-Dimensional Self-Esteem Scale, the Suicide Probability Scale, and a personal information form. Pearson correlation analysis and Hierarchical Multiple Linear Regression analysis were employed in the analysis of the data obtained from the research. In the study, it was found that gender, age, suicide attempt, communication with the mother, communication with the father, psychological distress, self-esteem, and perception of God explained 58% of the variance in suicide risk. Psychological distress had the strongest positive association with suicide risk (β = 0.136, p < 0.001), while self-esteem had the strongest negative relation (β = − 0.454, p < 0.001). In conclusion, it was determined that the female gender, suicide attempt, and psychological distress increased the risk of suicide, but that age, positive communication with parents, self-esteem, and positive perception of God decreased it. The findings of the research were discussed in light of the literature.

    Leveraging blockchain in response to a pandemic through disaster risk management: an IF-MCDM framework

    Peker, Iskender; Ar, Ilker Murat; Erol, Ismail; Searcy, Cory

    The COVID-19 pandemic has underscored the necessity for strategic approaches to manage global catastrophes. This study argues that disaster risk management (DRM) is an essential approach to mitigate the impact of global calamities, such as a pandemic. However, due to the uncertainty emerging from variables such as time and demand, managing DRM effectively involves high complexity. Blockchain technology (BcT) can be implemented to help address these challenges due to its potential to build trust, transparency, and accountability in complex operations. However, no research has quantitatively examined the applicability of BcT in the sub-dimensions of DRM to address the COVID-19 pandemic. The goal and scope of this study is to explore the role of BcT in DRM operations during the COVID-19 pandemic through an Intuitionistic Fuzzy Multi-Criteria Decision Making (IF-MCDM) framework. More specifically, the Intuitionistic Fuzzy Analytic Network Process (IF-ANP) method was utilized to calculate the weights of key criteria (i.e., BcT benefits), while Intuitionistic Fuzzy VIKOR (IF-VIKOR) was used to prioritize the alternatives (i.e., the sub-dimensions of DRM). The findings of this study are threefold. First, supporting effective coordination turned out to be the most essential benefit of BcT to build resilience in response to the COVID-19 pandemic. Second, disaster management was found to be the most appropriate DRM sub-dimension for possible BcT implementation during the COVID-19 pandemic. Lastly, eleven distinct activities involved in disaster management and governance and financial protection were discovered to be the most applicable for BcT. The findings of this study could assist disaster risk managers to assess whether (or not) BcT is suitable for the sub-dimensions of DRM to build national and organizational resilience in the wake of the COVID-19 pandemic.

    Breast cancer-related apps in Google Play and App store: evaluate their functionality and quality

    Aydin, Aydanur; Gursoy, Ayla

    Aim: This study aimed to evaluate the functionality and quality of breast cancer apps that can be accessed from Turkey. Methods: In this study, a systematic search strategy was used to identify free mobile apps on breast cancer available in the App and Google Play stores. According to the study’s PRISMA flowchart, 707 apps met the inclusion criteria. The Mobile App Rating Scale (MARS) assessed the quality of the apps. Results: Mobile apps focused on the categories of communication, education, and treatment order/plan. The mean MARS quality score for all apps was 3.4, and according to the mean score of the subscales, they were categorized as functionality, aesthetics, information quality, and participation. In addition, the mean scores of the subscales were listed on MARS as functionality, aesthetics, knowledge quality, and participation. Conclusion: Nowadays, “e-health” apps are attracting attention in the treatment of health problems. While the apps in download stores appear to provide basic information about breast cancer, they offer limited and personalized problem management related to prevention, early detection, and screening. Support from healthcare professionals and further efforts can be made to develop innovative technologies and apps that include evidence-based informational content about breast cancer. Implications for Cancer Survivors: In the process of breast cancer information, survivors can be encouraged to manage this process using e-health services.
