- ItemA modern approach to data privacy with federated learning(Maltepe University, 2023) Kalkavan, Ziya Can; Şahinaslan, Ender; Şahinaslan, Önder; 122635Today, information technologies and their usage areas are increasing day by day. Advanced technologies such as the internet of things, smart devices and applications, machine learning and arti cial intelligence are a driving force in the spread of their usage areas. The increase in prevalence and use also increases the production and sharing of data. This increase causes various security problems and concerns in terms of data privacy. Therefore, a balance has to be struck between the need for data sharing and its security. For this purpose, the use of federated learning methods has been examined. Traditional data sharing methods focus on centralized solutions for the processing of private and sensitive data of data subjects, but this causes various problems and raises concerns in the sharing of sensitive data. In the federated learning model, it trains locally without data sharing. It has a distributed arti cial intelligence approach that can run di erent resources together. Thus, it o ers an alternative solution that can help address data privacy concerns arising from the traditional method. In this study, the basic principles, usage areas, advantages and difficulties of federated learning, which is also accepted as a modern approach in data privacy, are discussed. The data and examples obtained in the study will be presented.
- ItemBibliometric analysis and mapping of the benefits and challenges of cloud ERP systems(İstanbul Üniversitesi, 2023) Şahinaslan, Önder; Şahin, Ahmet; Şahinaslan, Ender; 122635Enterprise resource planning is an effective tool in achieving management goals. Cloud ERP systems and applications are platform-independent offerings of this management tool in a cloud environment. This study was carried out to make sense of the advantages, difficulties and relationships of the cloud ERP system with scientific studies. For this purpose, the Scopus, Web of Science and Google Scholar databases and the Publish or Perish, WOSviewer and Excel applications were used. Statistical analysis, text mining, word network association, visual mapping and trend analysis were performed. As a result of the analysis, it was found that the total rate of publications produced in the last 3 years was 43%, the most cited work was Springer (20%) and the country was the USA (10%). It was determined that the three most frequently used keywords were ‘cloud ERP’, ‘ERP system’ and ‘ERP’. A strong correlation was found between ‘study’ and ‘challenge’ in text mining. The challenge was closely related to ‘SMEs’, ‘data’, ‘provider’, ‘technology’, ‘literature’ and ‘cloud environment’. In recent studies, the concept of ‘cloud ERP implementation’ in SMEs has come to the fore.
- ItemComparison of clinical and radiological results of lateral retinacular release or lateral retinacular lengthening methods combined with medial retinaculum plication in patellofemoral instability(Cureus INC, 2022) Saylık, Murat; Bilgin, Yücel; Atıcı, TeomanIntroduction In this study, we aimed to compare the clinical and radiological results of patients who underwent medial retinaculum plication (MRP) combined with lateral retinacular release (LRR) or lateral retinacular lengthening (LRL) with the diagnosis of patellofemoral (PF) instability. Methods In our study, we retrospectively analyzed 75 knees of 75 adult patients (43 females and 32 males) who underwent MRP+LRR or MRP+LRL due to PF instability without osseous pathologies. Patients were divided into two groups (MRP+LRR and MRP+LRL) according to the surgical method. The clinical and radiological results of the two groups were compared. Results MRP+LRL surgery was performed on 45 knees and MRP+LRR surgery on 30 knees. The mean age was 26.5 (18-43) years. There was no significant difference between the two groups in the change in patellar lateral shift (PLS) (p=0.429) and congruence angle (CA) (p=0.218) values. However, there was a significant difference between the two groups in the change in patellar tilt angle (PTA) (p=0.009) and lateral patellofemoral angle (LPFA) (p<0.001) values. The change in PTA and LPFA values was higher in the MRP+LRL group. There was no significant difference between the two groups in terms of pre-operative and post-operative Lysholm knee scoring scale (p=0.205, p=0.228), Kujala pain scale (p=0.393, p=0.596), and Tegner activity level scale values (p=0.121, p=0.899). Conclusions MRP+LRR or MRP+LRL provided successful results for correcting the instability in PF instability without osseous pathologies such as patella alta, tibial tubercle-trochlear groove (TT-TG) dysplasia, trochlea dysplasia, genu valgus, and tibial-femoral torsion. While PTA and LPFA values improved more with the MRPLRL method, clinical results were similar in both methods.
- ItemEvolution of software development process from past to future: an important reflection of digital transformation(Maltepe University, 2023) Nizamoğlu, Yekta Buğrahan; Şahinaslan, Ender; Şahinaslan, Önder; 122635; Değer, Özkan; Çakallı, HüseyinThe software development process has undergone a great evolution from past to present. There is a rapid change from traditional software development methods to modern and innovative approaches.

This will a ect all environments that produce, operate and use the software and will cause radical changes in usage. In this study, the change and current situation of the software development process from past to present will be discussed. Predictions will be shared on how and in what way digital transformation and technological advances may a ect the process in the future.
- ItemFashioning the self in Jean Rhys’s voyage in the dark and good morning, midnight(Çankaya Üniversitesi, 2024-04) Koç, Nesrin; 13778Jean Rhys held a deep passion for fashion and stylish attire. Her perspective on fashion, as an instrument of adopting “a second skin” finds expression in her focus on fashioning the self, a recurring motif in Rhys’s oeuvre. The physical difficulty Rhys’s female characters, whose lives bear strong similarities to her own, have in obtaining fashionable clothes represents the broader struggles they go through as the objects of the patriarchal and colonial gaze, in their voyages through the physical and metaphorical darkness of urban spaces like Paris and London in the early 1900s. Focusing on two of these women, Anna of Voyage in the Dark and Sasha in Good Morning, Midnight, for whom fashionable clothing appears to be the only way of navigating the modern society which marginalizes them, this study explores Rhys’s multilayered portrayal of fashion as a reflection of the near impossibility of attaining a cohesive sense of self, mirroring the characters’ struggles in fashioning their inner and outer selves.
- ItemHope and psychological resilience in primary caregivers of patients with a chronic mental illness followed in a community mental health center(Elsevier, 2024-03) Erkuş, Şeyma; Babacan Gümüş, Aysun; 372023Purpose: The aim of this study is to examine hope and psychological resilience in primary caregivers of patients with a chronic mental illness. Design and methods: The descriptive study was conducted on 297 caregivers in community mental health centers in Turkey. Data were collected using the Introductory Information Form, Dispositional Hope Scale and the Resilience Scale for Adults. Findings: Hope and psychological resilience of primary caregivers of patients with a chronic mental illness were moderate. To sociodemographic and caregiver characteristics; caregivers who are over 40 years old, lost his/her spouse, low education level, housewife or retired, unemployed, who evaluated their incomes low, mother, living in the same house with the patient, caring for ten years or more, caring for another patient and not getting help in care had lower hope and resilience levels. Compared to patients with a diagnosis of bipolar disorder, caregivers of patients with schizophrenia had lower hope and psychological resilience levels. Conclusions: Primary caregivers of patients with a chronic mental illness should be supported in terms of hope and psychological resilience.
- ItemHow close are interprofessional debriefers to meet the INACSL standards of debriefing practices? a qualitative study(2023-12) Özata, Kevser; Caz, Büşra; Sarmasoğlu Kılıkçıer, Şenay; 167438Aim: This study aims to determine whether the debriefings performed by different health professions for nearly a decade meet the INACSL standards of best debriefing practices. Methods: In order for learning to occur in simulation, there must be a adequate debriefing session. An adequate debriefing should be based on the criteria described in the standards of best practices published by the International Nursing Association for Clinical Simulation and Learning (INACSL). A high quality, adequate, and effective debriefing must be carried out in accordance with each standard. Results: Most of the debriefers are female. Over half had two years or less experience with simulation, and a quarter had training in simulation or debriefing. The results are presented in five contexts (Competent Debriefer, Environment, Effective Debriefing, Theoretical Framework, and Objectives and Outcomes.), which conform to the four standards covered by the INACSL standards of best practices. Conclusions: Except for the feedback, the debriefings do not meet the INACSL standards of best practices. However, the debriefers are aware of the importance of debriefing and are willing to improve their skills. Most of the debriefers have learned debriefing from observation or the literature. With this study, it was ensured that debriefers gained awareness in terms of INACSL standards. At the same time, this study will also provide awareness about the standards for the literature.

- ItemMultisource reflections on assessment of nursing students' first clinical practice and predictions for 360-degree assessment: a qualitative study(Hacettepe Üniversitesi, 2023-12) Bayzat, Çiğdem; Sarmasoğlu Kılıkçıer, Şenay; 167438Aim: This study was conducted to explain the current situation regarding the assessment of nursing students during their first clinical practice and to determine the views on 360-degree assessment, an innovative approach, from a multi-source perspective. Material and Methods: In this qualitative case study, individual interviews were conducted with nine instructors, focus group interviews were conducted with twenty-three nursing students, and documents were examined. Data were collected between 7 August 2019–22 November 2020. The data were analyzed in line with the descriptive analysis approach. Results: While reflections on the current situation were generated in line with the findings obtained from three data sources, the context of predictions on 360-degree assessment was generated in line with the findings obtained from interviews with students and instructors. Reflections on the current situation context are analyzed under assessors, competencies, methods and tools, feedback, challenges, and suggestions themes. Predictions on 360- degree assessment context are analyzed under assessors, frequency, tools, setting, benefits, and challenges themes. Conclusion: According to the results of the data triangulation, the most important issues regarding the assessment of nursing students during first clinical practice were the high student/instructor ratio and the fact that only instructors are officially assessors. Instructors and students approached positively to the 360-degree assessment, but they also shared some concerns.
- ItemPrediction of parking space availability using ARIMA and Neural Networks(TMMOB Makina Mühendisleri Odası, 2023) Sebatlı Sağlam, Aslı; Cavdur, FatihIt may be critical for drivers to have information about the occupancy rates of the parking spaces around their destination in order to reduce the traffic density, a non-negligible part of which caused by the trips to find an available parking space. In this study, we predict parking occupancy rates (and thus, space availability) using three different techniques: (i) auto-regressive integrated moving average model, (ii) seasonal auto-regressive integrated moving average model and (iii) neural networks. In the implementation phase, we use the data set of the on-street parking spaces of the well-known “SFpark” project carried out in San Francisco. We take into account not only the past occupancy rates of parking spaces, but also exogenous variables that affect the corresponding occupancy rates as day type and time period of the day. We make predictions with different model structures of each of the considered methods for each parking space with different parking occupancy patterns in the data set and then compare the results to find the best model design for each parking space. We also, evaluate the results in terms of the superiority of the methods over each other and note that the performance of neural networks is better than those of the other approaches in terms of the mean squared errors.
- ItemProblems and opportunities of artificial intelligence(İnönü Üniversitesi, 2022) Gürsakal, Necmi; Çelik, Sadullah; Batmaz, Bülent; 16040This article reviews Artificial Intelligence (AI)’s challenges and opportunities and discusses where AI might be headed. In the first part, it was tried to reveal the differences between Symbolic AI and Deep Learning approaches, then long promises but short deliveries of AI were mentioned. The problems of AI are that the media has high expectations about artificial intelligence and keeps the problems and restrictions it creates low. Today, while AI is stuck with issues such as deepfake applications and carbon footprints that create moral and climatologic problems; on the other hand, it is struggling with problems such as deep learning models requiring huge amounts of data. Another problem with deep learning is that deep learning models are a blackbox and not open to improvements because it is not known where mistakes were made. Among the new paths ahead of AI are Hierarchical Temporal Memory (HTM) models and hybrid models that generally try to bridge the gap between Symbolic AI and Connectionist AI. If we consider that the most important leaps in AI have been made with the features of the brain that AI can imitate, then the developed HTM models may also be a new opportunity for AI.

- ItemThe effect of an educational video on patients' bowel preparation before colonoscopy: a single-blind randomized controlled study(Termedia Publishing House LTD, 2023) Güneş, Ayşegül; Tekin, Yasemin Eda; El, Çiçek; Bektaş, Hasan; 292320Background. The objective of this research was to assess the efficacy of bowel preparation (BP) and colonoscopy compliance of video training given to patients prior to colonoscopy. Material and methods. In this single-blind randomized controlled study, patients in the control group received traditional written instructions with the same content as oral instructions. A total of 139 patients were included in the study, 70 of whom were allocated to the video education group, and 69 to the traditional education group. After the procedure, both groups’ BP quality and satisfaction with education were measured. Sociodemographic Characteristics Form, Boston Bowel Preparation Scale, Colonoscopy Preparation Compliance Form, and Education Satisfaction Form were used in the study. Results. The BP quality scores of the patients in the video group were found to be higher than the traditional method (p<0.05). In addition, it was found that the educational satisfaction scores, general BP compliance score, solid diet compliance scores, and liquid diet compliance scores were higher in the video group than in the traditional method patients (p<0.05). Conclusions. Video-based colonoscopy preparation training is an effective alternative to traditional methods.
- ItemThe effects of two different cold application times on edema, ecchymosis, and pain after rhinoplasty: a randomized clinical trial(Elsevier, 2024-01) Tekin, Yasemin Eda; İyigün, Emine; Karakoç, Ömer; 292320Purpose: This study was performed to determine the effects of different cold application times to the periorbital area after rhinoplasty on edema, ecchymosis, and pain. Design: A randomized clinical study. Methods: Patients were divided into two groups, and cold application was applied to one group for 4 hours and to the other for 48 hours. The cold application was applied with ice packs for 20 minutes every hour to the periorbital region in both groups. Data were collected with the Patient Information Form, Scoring Diagram for Edema, the Scoring Diagram for Ecchymosis, and the Visual Analogue Scale for Pain. Findings: Periorbital edema, eyelid ecchymosis, and pain were not significantly different between the two groups. The mean edema score of the 48-hour group was 0.87 ± 0.93, while the mean edema score of the 4-hour group was 0.70 ± 0.87 (P = .48) on the 2nd day. The mean ecchymosis score was found as 2.03 ± 1.12 in the 48-hour group and 2.10 ± 1.09 in the 4-hour group (P = .817). The mean pain score was 12.50 ± 17.40 in the 48-hour group and 13.00 ± 16.00 in the 4-hour group (P = .98). Conclusions: The effects of 48-hour and 4-hour cold applications are similar. Cold application for 4 hours may be recommended to patients who undergo rhinoplasty, as it is more practical and easier to apply than the 48-hour practice.
- ItemThe mediating role of emotion lability and emotion regulation in the relationship between social-emotional adaptation with behavior regulation and social skills among preschool children(Muhammed Yıldız, 2023-12) Sezgin, Esin; Bilge, Yıldız; Çelik, Burçin; Sevuk, Esma Nur; 230880Self-regulation is defined as an individual's ability to control and regulate their own behavior; this skill, forming the foundation of social adjustment, influences one's ability to interact with their environment and manage relationships. Emotion regulation, on the other hand, involves the ability to manage emotional responses and is believed to establish a critical connection between social adjustment and self-regulation. In this study, the aim is to determine the mediating role of emotion regulation in the relationship between behavioral regulation, social skills, and social-emotional adjustment skills using two different models.The study included a total of 216 children aged 5 and 6. Data were collected using the Socio-Demographic Information Form, Emotion Regulation Scale (ERS), Child Behavior Rating Scale (CBRS), and Marmara Social-Emotional Adaptation Scale (MSEAS). When socio-demographic variables were evaluated in terms of social competence and social-emotional adjustment scores according to gender, significant differences were found in favor of girls. Significant differences were also found in favor of children with working mothers when evaluated based on the mother's employment status. There were moderate significant correlations found between emotion regulation, child behavior assessment, and social-emotional adjustment. According to the mediation analyses, there was a partial mediating effect of emotion variability/negativity and emotion regulation in the relationship between behavior regulation and social-emotional adjustment. Similarly, there was a partial mediating effect of emotion variability/negativity and emotion regulation in the relationship between social competence and social-emotional adjustment. It is thought that the finding that children's emotion regulation and emotion variability/negativity mediate the relationship between social-emotional adjustment, social competence, and behavior regulation will contribute to the literature.

- ItemUtilizing large language models for EFL essay grading: an examination of reliability and validity in rubric-based assessments(Wiley, 2024-05) Yavuz, Fatih; Çelik, Özgür; Yavaş Çelik, Gamze; 131069This study investigates the validity and reliability of generative large language models (LLMs), specifically ChatGPT and Google's Bard, in grading student essays in higher education based on an analytical grading rubric. A total of 15 experienced English as a foreign language (EFL) instructors and two LLMs were asked to evaluate three student essays of varying quality. The grading scale comprised five domains: grammar, content, organization, style & expression and mechanics. The results revealed that fine-tuned ChatGPT model demonstrated a very high level of reliability with an intraclass correlation (ICC) score of 0.972, Default ChatGPT model exhibited an ICC score of 0.947 and Bard showed a substantial level of reliability with an ICC score of 0.919. Additionally, a significant overlap was observed in certain domains when comparing the grades assigned by LLMs and human raters. In conclusion, the findings suggest that while LLMs demonstrated a notable consistency and potential for grading competency, further fine-tuning and adjustment are needed for a more nuanced understanding of non-objective essay criteria. The study not only offers insights into the potential use of LLMs in grading student essays but also highlights the need for continued development and research.
- ItemValue education in elementary ages(IGI Global, 2023) Sayan, Hamiyet; 140851; Demircioğlu, AytekinValue education is the teaching and learning of values as empathy, respect, responsibility, etc. in schools. It aims to feed moral development and ethical advances to array students and equip them with the skills to navigate complex social situation. As an important part of education, value education is interested in developing moral values and ethics of the students. It also helps these students develop understanding and evaluating of the importance of these values like respect, honesty, empathy, and the like. They understand how to manage and live satisfactory quality lives.
