- 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.
- ItemBilateral locked posterior shoulder dislocation overlooked for 15 months treated with the modified McLaughlin procedure: A case report(Bayçınar Tıbbi Yayıncılık, 2023) Saylık, Murat; Gökkuş, KemalNeglected bilateral posterior shoulder dislocation is a rare injury caused primarily by an epileptic seizure. The injury is usually associated with a reverse Hill-Sachs lesion in the anteromedial aspect of the humeral head. The modified McLaughlin technique may avoid instability and osteoarthritis when 20 to 40% of the articular surface is affected by reverse Hill-Sachs. In this article, we present the clinical results of a case overlooked in the literature for the longest time, i.e., for 15 months. A 46-year-old male patient was receiving treatment for epilepsy for five years. There was no fall or trauma in the four seizures he had during this time. The last seizure was 15 months ago. When the patient presented to our clinic, both shoulders were symmetrically deformed, the anterior shoulder contour disappeared (empty socket sign), and there was a loss of upper contour. The computed tomography (CT) scan revealed a posteriorly locked dislocation with a reverse Hill-Sachs lesion in 32% of the left shoulder and 36% of the right shoulder. We applied the modified McLaughlin procedure to the dominant right shoulder and, two months later, we used it to the left shoulder (with a graft taken from the anterior superior iliac spine). At one-year of follow-up, both shoulders were moderately functional: forward elevation left 70° and right 50°, abduction left 40° and right 60°, and internal rotation: the back of the hand could touch the fifth lumbar vertebra. Meanwhile, the patient did not suffer from recurrent dislocation. The pre- and postoperative Constant-Murley Scores for the right and left shoulder were 30/52 and 11/48, respectively. Although the operational outcomes using the modified McLaughlin technique were not ideal, with no recurrence, the patient seemed to be satisfied with this outcome. In conclusion, in neglected locked shoulder fracture-dislocations, the modified McLaughlin technique is a method that can respond to the pathophysiology by eliminating reverse Hill–Sachs lesion.
- 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.
- PublicationDeconstructing the language laws: Arundhati Roy’s linguistic strategies in The God of small things(Eskişehir Osmangazi Üniversitesi, 2023) Koç, Nesrin; Koç, NesrinArundhati Roy’s The God of Small Things (1997) is a story which portrays how things deemed to be the smallest are connected to, shaped, and constructed by the bigger discourses of history, colonialism, gender, caste, and religion which define the subject. With her linguistic strategies aiming at deconstruction of the language, Roy unveils how the voice of the subaltern is located on the margins of the dominant discourses, and therefore, listening to the subaltern’s voice requires dwelling on the alternative spaces of existence constructed by the subaltern. Estha’s refusal to speak, Ammu, Velutha and Rahel’s resistance to the laws that determine interpersonal relations and their use of the language of the body are among the significant examples of the mechanisms used by the subaltern to resist domination. By exploring Roy’s linguistic strategies through close reading and textual analysis of the silences and alternative linguistic positions of the postcolonial subject, who is further marginalised by gender, caste and religion, from a position that combines postcolonial theory with a Lacanian perspective, this study aims to highlight how Roy creates a unique linguistic expression through the subversive strategies she utilizes to disrupt hegemonic power structures and challenge the established norms of society, culture and language. Designing, constructing, deconstructing and reconstructing, as in the architectural profession in which she was trained, Roy transforms standard English into an effective tool of communicating the postcolonial subject’s experiences of subalternity.
- PublicationEnhancing reading strategies through literature selection in EFL classrooms(CV. Yudhistt Fateeh, 2024-04) Durak, Ayşegül; Yavuz, Fatih; 392831; 131069This study presents a detailed examination of how to enhance reading strategies with selected literary genres using the library research method. In addition to library resources, the information collection process has been monitored through various academic publications, articles and books, the data obtained has been analysed and the results have been evaluated. Discovering the efficacy of authentic texts demonstrates that it enhances reading comprehension and fosters the abilities of learners. The study also identifies key strategies such as skimming, scanning, guessing, and distinguishing implied and literal meaning strategies. These techniques play a significant role in learners’ capability of understanding authentic text. Drawing on theoretical frameworks, the study underscores the importance of integrating the strategies mentioned above into teaching reading to enrich deeper understanding and critical engagement with literature. As a result, using the selected strategies and literary sources can effectively equip EFL learners to understand the unknown parts of complex texts. Language acquisition and proficiency improvement in authentic text are facilitated by navigating.

- 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.
- ItemInterventional therapy of acute coronary syndromes in very old patient population and results of 2 years follow‑up(Springer, 2023) Boyraz, Bedrettin; Peker, Tezcan; Akgümüş, Alkame; Balun, Ahmet; 313898Background Research on cardiovascular treatment options and prognosis in very old age groups of patients is warranted. In our study, we evaluated and followed up on clinical conditions on admission and comorbidities of patients older than 80 years who were admitted to our hospital with acute myocardial infarction and shared our findings. Results A total of 144 patients were included in the study, with a mean age of 84.56 ± 5.01 years. No complications resulting in death or requiring surgery were observed in the patients. All-cause mortality was found to be related to heart failure, chronic pulmonary disease shock, and C-reactive protein levels. Cardiovascular mortality was correlated to heart failure, shock on admission, and C-reactive protein levels. No significant difference in mortality was observed between Non-ST elevated myocardial infarction and ST-elevation myocardial infarction. Conclusions Percutaneous coronary intervention is a safe treatment option with low complication and mortality rates in very old patients with acute coronary syndromes.

- PublicationInvestigation of the effects of computer-aided animations on conceptual understanding through metaphors: An example of artificial intelligence(ICETOL, 2022) Aydın, Sevim; Duman, Emel; Bertiz, Yasemin; Birişçi, Salih; 385249In this study, it was aimed to investigate the change in the conceptual understanding of "artificial intelligence". For this purpose, the determination of the metaphors related to the concept of artificial intelligence in the stages before and after watching the artificial intelligence-themed computer-aided animation developed within the scope of the study, and the assessment of change between them constituted the research problem. During the 2021-2022 academic year 39 Information Technologies (IT) teachers and 103 fifth grade students studying in a secondary school in Nilüfer District of Bursa participated in this study. A phenomenological design pattern was adopted throughout the research. In the first stage of the study, many concepts were revealed as a result of the questionnaire applied to determine the concepts that were difficult to teach by IT teachers, and among them the concept of "artificial intelligence" was determined. In the second stage of the study, students were asked to complete the statement "Artificial intelligence is like … because ..." to determine the metaphorical perceptions on the concept of artificial intelligence. Based on the themes obtained from the metaphor results, computer-aided animation on the concept of artificial intelligence was developed by the researchers. After the animation demonstration to students, the metaphorical data collection process was repeated and it was attempted to determine the change in the students' understanding of the concept of artificial intelligence. As a result of the study, although the conceptual categories regarding artificial intelligence generally had similar characteristics, it was observed that the justifications in the post-animation conceptual perceptions were more meaningful.
- PublicationMathematical model to upcycle end-of-roll leftover fabrics in apparel manufacturing(Sage, 2024-06) İşeri, Ali; Kılılaslan, Recep; 135066This study addresses the problem of end-of-roll leftover fabrics originating after the production of baby/child apparel. The ineffective management of these leftovers results in excess inventory, occupies storage space, and imposes economic and environmental loads. To address this challenge, a novel mathematical modeling approach is proposed. The model maximizes the upcycling of leftovers by incorporating these into the manufacturing of garments while adhering to marketing, production, and ordering constraints. This model also introduces the feasibility of ordering new fabrics with a penalty, as defined by the decision makers, to increase utilization. The model was tested using actual end-of-roll leftover data. The upcycling utilization of leftovers was calculated to be between 57% and 87%. Notably, at an upcycling rate of 58%, 96% of the utilized fabrics were sourced from leftovers. The case study results validate the model efficacy and provide insights into leftover-fabric management.
- 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.
- ItemOpen and arthroscopic excision of the distal clavicle for osteoarthritis of the acromioclavicular joint--results over 5 years(TMMOB Makina Mühendisleri Odası, 2022) Saylık, MuratObjective: Initially performed as open surgery, arthroscopic applications of distal clavicle excision (DCE) have gained prevalence in recent years. Literature reviews about the long-term results give no clear indication that one method is superior to the other. This study aims to compare the follow-up results of patients treated with arthroscopic and open DCE for more than five years and to detect the superiority of each method. Material and Method: The study involved 328 patients treated with DCE between February 2008 and April 2017. One hundred and fourteen patients (66 male and 48 female; 81 arthroscopic and 33 open surgery), who had their records available and under went no other surgery than DCE, were included in the study. The Disability of the Arm, Shoulder, and Hand (DASH) score and Visual Analogue Scale (VAS) were used to assess post-DCE shoulder functions and pain, respectively. Within the study's scope, surgery duration, excision extent, complications (frozen shoulder, hematoma, surgical site infection, and instability), and revisions were compared. Results: In the >5-year follow-up process, no statistically significant difference was observed between pre-DCE DASH and VAS values or between post-DCE DASH and VAS values of the two groups, one involving 32 patients who underwent open surgery and the other involving 82 patients treated with arthroscopic surgery. However, there was a statistically significant difference between the pre- and post-DCE DASH and VAS scores of both groups, and it was observed that both surgical methods were effective. No statistically significant difference was observed between the two groups regarding the surgery duration. Arthroscopic DCE was measured to be 4.70 mm on average, while the average measure for open surgery was 5.53 mm, which indicated a statistically significant difference between the two groups. However, no significant association was observed between the excision extent and the DASH and VAS scores. Furthermore, no significant difference was observed between complication and revision rates. Conclusion: In the >5-year follow-up of patients who underwent arthroscopic or open DCE due to their acromioclavicular joint osteoarthritis, which could not be treated with conservative treatment, no statistically significant difference was observed in the two groups' post-DCE DASH scores, VAS scores, complication rates, and revision rates. There was, however, a statistically significant difference between both groups' pre- and post-DCE VAS and DASH scores, and both methods were effective.
- 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.
