    (John Wiley and Sons Ltd, 2024-03-30) Aydın, Şahin; Aldara, Dieaa
    Information and communication technologies (ICTs) can play a crucial role in facilitating access to comprehensive information on the quality standards of Turkish hazelnut cultivars. In this regard, this study introduces a Hazelnut Databank System (HDS) that utilizes the microservices architecture, an integrated software system supported by the Internet of Things (IoT) and semantic web, to categorize Turkish hazelnut cultivars. The study focuses on developing microservices using various programming languages and frameworks. Specifically, C# on the.NET Core Framework was used for both microservices and the web-based application implemented through the ASP.NET Core MVC Framework. Mobile-based software applications were created using Xamarin. Forms, and the IoT application was developed using the Python programming language. The data storage is facilitated through the MS SQL Server database. Additionally, the study incorporates the implementation of a hazelnut species classification system using the DNN + ResNet50 machine learning model, achieving an impressive accuracy rate of 95.77%. The overall usability of the system was evaluated, resulting in a score of 42 out of 50. By providing detailed information on Turkish hazelnut cultivars, the HDS has the potential to greatly improve hazelnut production quality in Turkey and increase awareness of hazelnut agriculture among relevant stakeholders.

    Kur riskinden korunma araçları: veri analizi uygulaması
    (PressAcademia, 2024-01-15) Aydoğdu, Ayşegül; Çalış, Ercan
    Amaç- Döviz kurunda yaşanan dalgalanmalar yabancı para cinsinden vadeli işlem gerçekleştiren şirketleri kur riskine maruz bırakmaktadır. Kur riski işletmeleri uluslararası ödemeler dengesi, sermaye ve kredi akımları, yabancı para cinsinden borç ve alacaklar, hatta uluslararası ticari etkinliklere katılmasa dahi ulusal para biriminin değerinin değişmesinin sonunda olumlu ve olumsuz şekilde etkilemektedir. Bu nedenle işletmeler kur riskinden korunmak için çeşitli yöntemler kullanmaktadır. Bu çalışma ise firmaların karşı karşıya kaldığı döviz kuru risklerinin ölçümü ve yönetimine ilişkin bazı temel konuları, döviz kuru riskini ölçmede şu anda baskın olan metodolojileri ve kur riski yönetiminde geniş çapta kabul görmüş en iyi uygulamaları özetlemektedir. Bu araştırmanın amacı, döviz kurlarındaki hareketliliğin sebep olduğu kur risklerine karşı işletmelerin kullandıkları stratejileri tanıtmaktır. Bununla birlikte bu çalışmanın alt amaçları, işletmelerin finans yetkilililerin ünvanlarına ve işletmelerin büyüklüklerine göre döviz kuru risklerinden korunma araçlarından haberdar olma durumlarını, kullanım düzeylerini, bu araçları kullanmayanların kullanmamaktaki sebeplerini belirlemek, işletme içi stratejileri ve ekonomik riskten korunma stratejilerini de ortaya koymaktır. Yöntem- Araştırmanın ana kütlesini Marmara Bölgesinde faaliyet gösteren işletmeler oluşturmaktadır. Araştırmanın örneklemi ise Türkiye’de Marmara Bölgesinde dış ticaret yapan 200 işletmeden oluşmaktadır. Verilerin toplanmasında ise İşletmelerin İşlem Riskinden Korunmak İçin Uyguladıkları Stratejiler Ölçeği kullanılmıştır. Firmaların maruz kaldıkları kur riskinden korunabilmek için kullandıkları tekniklerin üzerinden elde edilen veriler tanımlayıcı istatistikler ile yorumlanmıştır. Bununla birlikte, elde edilen verilere tek yönlü ANOVA testi uygulanmıştır. Bulgular- Türkiye'nin Marmara Bölgesindeki 200 dış ticaret işletmesinden elde edilen verilere dayalı olarak, şirketlerin kur riskinden korunmak için kullandıkları yöntemlere dayalı betimsel istatistiklerin bulgularına bakıldığında şirketler için kur riski şirket sağlamlığı için önem arz etmektedir. Şirketlerin kur riskinden korunma araçları konusunda bilgili olduklarını ancak buna rağmen kullanmak konusunda çekimser davrandıklarını görmekteyiz. İşletmeler kur riskinden korunmak için çeşitli teknikler kullanmaktadır. Bununla birlikte, ANOVA testi ile işletmelerin finans yetkililerinin ünvanlarına ve işletme büyüklüklerine göre döviz kuru risklerinden işlem riskinden ve ekonomik riskten korunmak için uyguladıkları stratejiler incelendiğinde finans yetkililerinin ünvanlarına göre ve şirketlerin büyüklüklerine kullandıkları stratejiler, kullanım düzeyleri, haberdar olma düzeyleri ve ekonomik ve işlem riskinden korunma araçlarında değişkenlik olduğu görülmektedir. Sonuç- Kur risinden korunma araçları üzerine veri analizi uygulaması yapılan bu çalışmada, döviz kuru riskini yönetmek için işletmelerin karmaşık ve çeşitli stratejiler kullandığını göstermektedir. İşletmeler, döviz kuru riskine karşı koyabilmek ve karlılıklarını korumak için bu stratejilere başvurmak zorundadır. Bu bulgular aynı zamanda, döviz kuru riskinin yönetilmesinin işletmelerin finansal performansı ve işletme sağlamlığı üzerinde önemli bir etkisi olduğunu göstermektedir.

    Engineering four-qubit fuel states for protecting quantum thermalization machine from decoherence
    (Multidisciplinary Digital Publishing Institute (MDPI), 2024-01-10) Özaydın, Fatih; Sarkar, Ramita; Bayrakçı, Veysel; Bayındır, Cihan; Altıntaş, Azmi Ali; Müstecaplıoğlu, Özgür E.
    Decoherence is a major issue in quantum information processing, degrading the performance of tasks or even precluding them. Quantum error-correcting codes, creating decoherence-free subspaces, and the quantum Zeno effect are among the major means for protecting quantum systems from decoherence. Increasing the number of qubits of a quantum system to be utilized in a quantum information task as a resource expands the quantum state space. This creates the opportunity to engineer the quantum state of the system in a way that improves the performance of the task and even to protect the system against decoherence. Here, we consider a quantum thermalization machine and four-qubit atomic states as its resource. Taking into account the realistic conditions such as cavity loss and atomic decoherence due to ambient temperature, we design a quantum state for the atomic resource as a classical mixture of Dicke and W states. We show that using the mixture probability as the control parameter, the negative effects of the inevitable decoherence on the machine performance almost vanish. Our work paves the way for optimizing resource systems consisting of a higher number of atoms.

    Digital banking during the COVID-19 era in Turkiye
    (Sivas Cumhuriyet Üniversitesi, 2023-31-12) Oğuz, Ahmet Bünyan; Soykut Sarıca, Yeşim Pınar
    The Covid-19 pandemic which began in early 2020 in Wuhan, China and spread around the world, created a serious impact on personal and business life for all. While individuals tried to protect themselves from the pandemic and continue their lives, businesses also tried to cope with the change in individual consumer behaviour. This study analyses the digital banking usage trends in Türkiye, focusing on the Covid-19 pandemic period, between January 2020 and June 2022, under the precautions imposed by the government such as lock-downs, curfews and public access limitations to businesses, using available quarterly transaction and usage data on virtual credit cards, mail order and phone payments, contactless cards, domestic credit cards, number of credit and bank cards, digital banking, internet banking and mobile banking. Research findings suggest that while internet and digital banking usage increased, significant changes have been observed in contactless card, virtual credit card transactions indicating a shift in user preference in banking during the pandemic period either voluntarily or with the effects of the restrictions and intention to realize their transactions distancing themselves from the crowds. Further research analysing whether this shift is permanent or not is recommended.

    (Sage Publications Inc, 2023-12) Doruk, Can; Çaytemel, Berkay; Şahin, Erdi; Kara, Hakan; Samancı, Bedia; Abay, Sevinç Nisa; Bilgiç, Başar; Hanağası, Haşmet; Başaran, Bora; Enver, Necati; Rameau, Anais
    Objectives: Dysphagia is common in idiopathic Parkinson's disease (IPD) and is associated with impairments in both swallowing safety and swallowing efficiency. The goals of this study were to define post-swallow residue patterns in people with IPD and describe pathophysiological endoscopic findings affecting residue accumulation. Methods: This was a prospective single-blinded cross-sectional cohort study of patients with the diagnosis of IPD recruited from a Movement Disorder Clinic. Clinical variables included patient age, cognitive function, and measures of disease severity, and laryngoscopic examinations with a flexible endoscopic evaluation of swallowing (FEES) were completed for each patient. Visual Analysis of Swallowing Efficiency and Safety (VASES) was used to analyze FEES. Post-swallow residue outcomes and non-residue endoscopic outcomes including the Bowing index, Penetration Aspiration Scale (PAS) score, premature leakage, and build-up phenomenon were evaluated. Multiple regression models were used to evaluate factors affecting the residue at different anatomic levels. Results: Overall 53 patients completed the study. The multiple regression analyses showed a relation between (1) the presence of residue at the level of oropharynx and epiglottis with premature leakage, (2) the presence of residue at the level of the laryngeal vestibule and vocal folds with build-up phenomenon, and (3) the presence of residue at the level of the hypopharynx, laryngeal vestibule, and subglottis with airway invasion. Conclusion: Residue pattern during FEES is associated with specific swallow dysfunctions in IPD. Using residue localization and quantification may be a helpful tool in assessing the impact of targeted swallowing interventions in patients with IPD and dysphagia.

    Digital era for universities: soon or far
    (PressAcademia, 2023-07-30) Eşkinat, Ali; Teker, Suat
    Purpose- Over the Covid-19 crises, most universities keep increasing the use of hybrid model at various levels in all disciplines in their education system forced by the market demand. This paper reviews the evolution of university generations from university 1.0 to university 4.0 using a historical point of view. This paper intends to clarify whether digital era for universities, namely University 5.0, is soon or far advocating that a large number of completely digital universities may breakout and reach everywhere in the world with no barriers of language, time and locations, and competing with local and traditional universities in all sense after year 2030. Methodology- The study employs an online survey via convenience sampling based on quantitative research method. Employers/Managers, Academics and formal University Students were selected as three target population group located all around Turkiye. The aim was to test the 5 hypotheses of this study to clarify the time of digital era for universities. Findings- The analysis reveals that the 5 hypotheses are accepted and seen as valid. The empirical results show a significant difference between the gender variable and the importance given to digital education. Moreover, there was a significant difference in the mean scores of the significance of digitalization and the importance given to digital education based on education level variable. Then, there were differences in the significance of digitalization and the importance given to digital education concerning the social status variable in the collected data. Notably, a linear and significant relationship was revealed between the importance given to digital education by participants and the importance they attributed to digitalization. Furthermore, a linear and significant relationship was found between the importance given to digital education and the importance given to university education. Under these circumstances, the results reveal that digital education is concerned as a fact of digital era and higher education institutions are not immune of this transformation. Conclusion- Based upon the analysis, it can be concluded that the traditional university system will be evolved into a digital university system in a not-too-distant future. In other words, traditional prestigious universities are expected to continue whereas digital universities appear as destructive competitors. For this reason, it may be argued that universities will increase to provide hybrid model education depending on the market demand until 2030, whereby it will be applied at different rates in education disciplines, such as of medicine, engineering, social sciences and many others. After 2030 traditional universities will continue to use blended learning whereas digital higher education institutions will start their inevitable growth.

    Korkunun psikolojik sağlamlık üzerindeki yordayıcı rolü: adil dünya inancı ve sıkıntıya tolerans
    (Hayrettin ivgin, 2023-06-27) Kazancı, Dilara; Akçinar, Berna
    Bu araştırmada korkunun bireylerin psikolojik sağlamlıkları üzerindeki yordayıcı rolü ile adil dünya inancı ve sıkıntıya dayanma kapasitesi arasındaki ilişkilerin incelenmesi amaçlanmıştır. Korkuyu inceleyen araştırmalarda katılımcılara korkuya neden olan uyaranların genellikle laboratuvar ortamında sunulduğu görülmektedir. Günlük yaşantılarında gerçek bir tehditle karşı karşıya olan bireylerin yer aldığı araştırmalar sayıca azdır. Bu çalışmada Dünya Sağlık Örgütü tarafından birçok kişide yaygın korkuya neden olduğu açıklanan gerçek bir tehdit olan Covid Korkusu ele alınmıştır. Araştırmanın örneklemi yaşları 18 ile 66 arasında değişen 300 katılımcıdan (226 kadın, 74 erkek) oluşmaktadır. Araştırmada Covid 19 Korkusu Ölçeği, Sıkıntıya Dayanma Ölçeği ve Adil Dünya İnancı Ölçeği kullanılmıştır. Araştırmadan elde edilen verilere göre bireylerin korku düzeyleri ile psikolojik sağlamlık düzeyleri arasında negatif yönlü ve istatistiksel olarak anlamlı bir ilişki vardır. Bireylerin korku düzeyi yükseldikçe psikolojik sağlamlık düzeyleri azalmaktadır. Bununla birlikte korku düzeyi psikolojik sağlamlık düzeyini yordamaktadır. Bireylerin sıkıntıya dayanma kapasiteleri ile psikolojik sağlamlık düzeyleri arasında pozitif yönlü ve anlamlı bir ilişki vardır. Bireylerin sıkıntıya dayanma kapasiteleri yükseldikçe psikolojik sağlamlık düzeyleri yükselmektedir ve sıkıntıya dayanma kapasitesi psikolojik sağlamlık düzeyini yordamaktadır. Genel adil dünya inancı ile psikolojik sağlamlık arasındaki ilişki beklenenin aksine negatif yönlü olmuştur. Bu bulgunun pandeminin kaotik yapısı ve bu dönemde şahit olunanlar sonucunda adil dünya inancına sahip bireylerin yaşamış oldukları olası bilişsel çelişki ile ilişkili olduğu düşünülmüştür. Bu konuda daha fazla araştırma yapılması önerilmiştir. Bireylerin psikolojik sağlamlık seviyelerinin cinsiyet ve medeni durumlarına göre farklılaştığı gözlemlenmiştir. Erkeklerin psikolojik sağlamlık düzeyleri kadınlara göre daha yüksektir. Evli katılımcıların psikolojik sağlamlık düzeyleri evli olmayanlara göre daha yüksektir. Araştırma sonuçları ilgili literatür kapsamında tartışılmıştır.

    Rumination and the default mode network (DMN): a brain network review
    (Denta Florya ADSM Limited Company, 2023-06-01) Koçyiğit Ocak, Buket; Erdoğdu, Emel
    Rumination is one of the most common repetitive negative thinking patterns and described as a pathological structure that involves focusing negatively on the past events and their consequences. Two subtypes of rumination are defined, while brooding is considered as an unsuccessful problem-solving attempt focusing on the consequences of depressive symptoms, reflection is considered as a relatively successful problem-solving attempt focusing on the causes of the depressive state. Within the last decade, rumination has been studied by its connection with the activity of the Default Mode Network (DMN), which is known as a structure that connects specific brain regions that increase their activity during the resting state (rs) and was associated with selfreferential thinking, memory and mind wandering. Additionally, a few recent studies suggest that besides the activity within the DMN, some networks working simultaneously with the DMN may also play a significant role in rumination. Therefore, five rs-fMRI (resting state functional magnetic resonance imaging) articles assessing the relationship between rumination and DMN are discussed in this study. These studies show that while the communication of some DMN subsystems are increased during the process of ruminative thinking, some subsystems of DMN seems to communicate less. Moreover, some evidence suggests that DMN synchronization might be impaired in high-trait ruminators. Finally, it has been tried to emphasize the points and suggestions that are valuable for future studies.

    Objective: The purpose of this study is to analyze the possible mediatör effect of mindfulness in the relationship between perceived stress and quality of life in pediatric asthma. Material and Method: The sample of this study consisted of 100 asthmatic children aged between 9-12 years who applied to the outpatient clinic of Istanbul University, Istanbul Faculty of Medicine, Division of Pediatric Allergy. Sociodemographic information forms, Perceived Stress Scale in Children (8-11 years), Child and Adolescent Mindfulness Measure (CAMM), and Pediatric Asthma Quality of Life Questionnaire (PAQLQ) were used as data collection tools. Linear hierarchical regression analysis was used during the process of analyzing data. Results: It has been identified that mindfulness has a partial mediatör effect on the relationship between perceived stress and quality of life (p = 0.000). The presence of a partial mediator effect of mindfulness has been determined in the relationship between perceived stress and symptoms which is the subscale of quality of life (p = 0.000). Finally, it has been demonstrated that mindfulness has a partial mediator effect on the relationship between perceived stress and emotional function which is another subscale of quality of life (p = 0.000). The mediating role of mindfulness in the relationship between perceived stress and activity limitations could not be analyzed due to the lack of a significant correlation between activity limitations which is the subscale of quality of life and mindfulness (p=0.178). Conclusion: It can be helpful to add psychotherapy interventions involving mindfulness practices to asthma treatment for better control of the disease in children.

    Bağlanma stilleri ile ilişki merkezli ve partner odaklı obsesif kompulsif belirtiler arasındaki ilişkide evlilik uyumunun aracı rolü
    (Klinik Psikoloji Araştırmaları Derneği, 2023-05-02) Özel, Ebru Pelin; Karaköse, Selin
    Yetişkinlikte yakın ilişkilerde güvensiz bağlanmanın ilişkinin niteliğini etkilediği ve çeşitli psikopatolojiler ile yakından ilişkili olduğu bilinmektedir. İlişki merkezli ve partner odaklı obsesyon ile kompulsiyonlar alanyazına son yıllarda kazandırılmış kavramlardır ve önemli obsesif kompulsif belirtiler içerikleri olarak ele alınmaktadır. Geçmiş çalışmalarda güvensiz bağlanma örüntüleri ile ilişki merkezli ve partner odaklı obsesyon ve kompulsiyonlar bir arada ele alınsa da, alan yazında evlilik uyumunun bu ilişkideki aracı rolünü inceleyen bir çalışma henüz yer almamaktadır. Bu çalışmanın amacı, yetişkin bağlanma stilleri ile ilişki merkezli ve partner odaklı obsesif kompulsif arasında evlilik uyumunun aracı rolünü araştırmaktır. Araştırmanın örneklemi, İstanbul’da yaşayan 22-70 yaş (Ort. = 40.75, SS = 10.57) arasında 380 evli bireyden (200 kadın, 180 erkek) oluşmaktadır. Çalışma kapsamında Sosyodemografik Bilgi Formu, Yakın İlişkilerde Yaşantılar Envanteri-2 (YİYE-2), Çift Uyum Ölçeği (ÇUÖ), Romantik İlişki Obsesyon ve Kompulsiyonlar Ölçeği (RİOKÖ) ile Partnere İlişkin Obsesif Kompulsif Belirtiler Ölçeği (PİOKBÖ) katılımcılara sunulmuştur. Bulgular, evlilik uyumunun kaygılı ve kaçınmacı bağlanma stili ile ilişki merkezli ve partner odaklı obsesif kompulsif belirti düzeyi arasında aracılık rolü olduğunu göstermektedir. Araştırma bulguları, ilişki merkezli ve partner odaklı obsesif kompulsif belirtiler söz konusu olduğunda klinisyenlerin evlilik uyumuna ek olarak güvensiz bağlanma stillerine yönelik de müdahalelerde bulunmasının önemine işaret etmektedir.

    Bu araştırmanın temel amacı son ergenlik dönemindeki bireylerin dissosiyatif bulguları ile ruminasyon düzeyleri arasındaki ilişkide duyguları ifade etmenin aracı rolünü? incelemektir. Araştırmaya 18-24 yasları arasında olan 502 kişi katılmıştır. Veriler, Sosyodemografik Bilgi Formu, Dissosiyasyon Ölc?eg?i (DIS-Q), Ruminatif Düşünce Bic?imi Ölc?eg?i (RDBÖ) ve Duyguları İfade Etme Ölc?eg?i (DİEÖ) aracılıg?ıyla toplanmıştır. Araştırmadan elde edilen bulgulara göre son ergenlik dönemindeki bireylerin ruminasyon düzeyleri arttıkc?a duyguları ifade etme düzeylerinin azaldıg?ı ve dissosiyasyon düzeylerinin arttıg?ı; duyguları ifade etme düzeyleri azaldıkc?a dissosiyasyon düzeylerinin arttıg?ı görülmüştür. Son ergenlik dönemindeki bireylerin dissosiyatif bulguları ile ruminasyon düzeyleri arasındaki ilişkide duyguları ifade etmenin kısmi aracı etkisi oldug?u saptanmıştır. Araştırmamızın söz konusu deg?işkenlerin gec?miş araştırmalarda sınırlı sayıda incelenmesi ac?ısından literatüre katkı sag?ladıg?ı düşünülmektedir.
