Article Citation - WoS: 10Citation - Scopus: 10Higher Rates of Cefiderocol Resistance Among Ndm Producing klebsiella Bloodstream Isolates Applying Eucast Over Clsi Breakpoints(Taylor & Francis Ltd, 2023) Isler, Burcu; Vatansever, Cansel; Ozer, Berna; Cinar, Gule; Aslan, Abdullah Tarik; Falconer, Caitlin; Harris, Patrick N. A.BackgroundCefiderocol is generally active against carbapenem-resistant Klebsiella spp. (CRK) with higher MICs against metallo-beta-lactamase producers. There is a variation in cefiderocol interpretive criteria determined by EUCAST and CLSI. Our objective was to test CRK isolates against cefiderocol and compare cefiderocol susceptibilities using EUCAST and CLSI interpretive criteria.MethodsA unique collection (n = 254) of mainly OXA-48-like- or NDM-producing CRK bloodstream isolates were tested against cefiderocol with disc diffusion (Mast Diagnostics, UK). Beta-lactam resistance genes and multilocus sequence types were identified using bioinformatics analyses on complete bacterial genomes.ResultsMedian cefiderocol inhibition zone diameter was 24 mm (interquartile range [IQR] 24-26 mm) for all isolates and 18 mm (IQR 15-21 mm) for NDM producers. We observed significant variability between cefiderocol susceptibilities using EUCAST and CLSI breakpoints, such that 26% and 2% of all isolates, and 81% and 12% of the NDM producers were resistant to cefiderocol using EUCAST and CLSI interpretive criteria, respectively.ConclusionsCefiderocol resistance rates among NDM producers are high using EUCAST criteria. Breakpoint variability may have significant implications on patient outcomes. Until more clinical outcome data are available, we suggest using EUCAST interpretive criteria for cefiderocol susceptibility testing.Article Citation - WoS: 1Citation - Scopus: 1Effects of Cervical Mobilization on Balance and Proprioception in Patients With Nonspecific Neck Pain(Mosby-elsevier, 2024) Acet, Nagihan; Guzel, Nevin Atalay; Gunendi, ZaferObjective: This study investigates the effect of cervical mobilization on balance and cervical proprioception in patients with nonspecific neck pain. Methods: A prospective, double-blind, randomized clinical trial was conducted involving a 3-week treatment protocol for which 66 patients were randomly assigned to 2 groups. Both groups underwent conventional physiotherapy (hot pack and transcutaneous electrical nerve stimulation) twice a week for 3 weeks along with additional cervical mobilization in the mobilization group, and sham mobilization in the sham control group. Static and dynamic balance, cervical proprioception, cervical mobility, and pain intensity were evaluated using a Kinesthetic Skill Training System 3000 device, the "Joint Position Error Test," Cervical Range-of-Motion Instrument, and the visual analog scale, respectively. Results: After treatment, significant improvements were noted in dynamic balance, mobility, pain intensity (P < .001, P < .001, P < .001, respectively), and proprioception in the left direction of rotation in the mobilization group (P = .003) that were significantly greater than those observed in the sham mobilization group (P < .001, P < .001, P < .001, P = .003, respectively). Although a significant decrease was observed in the deficits of static balance (P = .044) and proprioception in the right direction of rotation (P = .011) after mobilization, the changes were similar in both the mobilization and sham mobilization groups (P = .192, P = .154, respectively). Conclusion: Cervical mobilization led to significant improvements in dynamic balance, pain intensity, mobility, and partial improvements to proprioception in a comparison with a sham mobilization group, while the effect on static balance was not significant.Article Citation - WoS: 4Citation - Scopus: 8Remote Rf Laboratory Requirements: Engineers' and Technicians' Perspective(Anadolu Univ, 2007) Cagiltay, Nergiz Ercil; Aydin, Elif Uray; Kara, Ali; Department of Electrical & Electronics Engineering; Software EngineeringThis study aims to find out requirements and needs to be fulfilled in developing remote Radio Frequency (RF) laboratory. Remote laboratories are newly emerging solutions for better supporting of e-learning platforms and for increasing their efficiency and effectiveness in technical education. By this way, modern universities aim to provide lifelong learning environments to extend their education for a wider area and support learners anytime and anywhere when they need help. However, as far as the authors concern, there is no study investigating the requirements and needs of remote laboratories in that particular field in the literature. This study is based on electrical engineers' and technicians' perspectives on the requirements of a remote laboratory in RF domain. Its scope covers investigation of the participants' perceptions toward computer mediated communication and it attempts to answer the questions: which studying strategies are preferred by the learners and what kind of RF laboratory content should be provided. The analysis of the results showed that, geographic independence, finding quickly the elements of past communication and temporal independence are declared as the most important advantages of computer-mediated communication. However, reading significant amount of information is a problem of these environments. In the context of how to show the content, respondents want to see shorter text on the screen. Therefore the instructions should include little amount of text and must be supported with figures and interactive elements. The instructional materials developed for such learner groups should support both linear and non-linear instructions. While analyzing the content to be provided, we have seen that, most of the participants do not have access to high level equipments and traditional experiments are considered as the necessary ones for both engineers and technicians.Article Citation - WoS: 3Citation - Scopus: 5Particle Swarm Optimization of the Spectral and Energy Efficiency of an Scma-Based Heterogeneous Cellular Network(Wiley, 2022) Noma-Osaghae, Etinosa; Misra, Sanjay; Ahuja, Ravin; Koyuncu, MuratBackground The effect of stochastic small base station (SBS) deployment on the energy efficiency (EE) and spectral efficiency (SE) of sparse code multiple access (SCMA)-based heterogeneous cellular networks (HCNs) is still mostly unknown. Aim This research study seeks to provide insight into the interaction between SE and EE in SBS sleep-mode enabled SCMA-based HCNs. Methodology A model that characterizes the energy-spectral-efficiency (ESE) of a two-tier SBS sleep-mode enabled SCMA-based HCN was derived. A multiobjective optimization problem was formulated to maximize the SE and EE of the SCMA-based HCN simultaneously. The multiobjective optimization problem was solved using a proposed weighted sum modified particle swarm optimization algorithm (PSO). A comparison was made between the performance of the proposed weighted sum modified PSO algorithm and the genetic algorithm (GA) and the case where the SCMA-based HCN is unoptimized. Results The Pareto-optimal front generated showed a simultaneous maximization of the SE and EE of the SCMA-based HCN at high traffic levels and a convex front that allows network operators to select the SE-EE tradeoff at low traffic levels flexibly. The proposed PSO algorithm offers a higher SBS density, and a higher SBS transmit power at high traffic levels than at low traffic levels. The unoptimized SCMA-based HCN achieves an 80% lower SE and a 51% lower EE than the proposed PSO optimized SCMA-based HCN. The optimum SE and EE achieved by the SCMA-based HCN using the proposed PSO algorithm or the GA are comparable, but the proposed PSO uses a 51.85% lower SBS density and a 35.96% lower SBS transmit power to achieve the optimal SE and EE at moderate traffic levels. Conclusion In sleep-mode enabled SCMA-based HCNs, network engineers have to decide the balance of SBS density and SBS transmit power that helps achieve the desired SE and EE.Article Citation - WoS: 1Citation - Scopus: 1Recycling Decommissioned Wind Turbine Blades for Post-Disaster Housing Applications(Mdpi, 2025) Turhan, Cihan; Durak, Murat; Saleh, Yousif Abed Saleh; Kalayci, AlperThe growing adoption of wind energy has resulted in an increasing number of decommissioned wind turbine blades, which pose significant disposal challenges due to their size, material composition, and environmental impact. Recycling these blades has thus become essential. To this aim, this study explores the potential of using recycled wind turbine blades in post-disaster housing applications and examines the feasibility of re-purposing these durable composite materials to create robust, cost-effective, and sustainable building solutions for emergency housing. A case study of a post-earthquake relief camp in Hatay, T & uuml;rkiye, affected by the 2023 earthquake, is used for analysis. First, the energy consumption of thirty traditional modular container-based post-disaster housing units is simulated with a dynamic building simulation tool. Then, the study introduces novel wind turbine blade-based housing (WTB-bH) designs developed using the same simulation tool. The energy consumption of these (WTB-bH) units is compared to that of traditional containers. The results indicate that using recycled wind turbine blades for housing not only contributes to waste reduction but also achieves 27.3% energy savings compared to conventional methods. The novelty of this study is in demonstrating the potential of recycled wind turbine blades to offer durable and resilient housing solutions in post-disaster situations and to advocate for integrating this recycling method into disaster recovery frameworks, highlighting its ability to enhance sustainability and resource efficiency in construction. Overall, the output of this study may help to present a compelling case for the innovative reuse of decommissioned wind turbine blades, providing an eco-friendly alternative to traditional waste disposal methods while addressing critical needs in post-disaster scenarios.Article Citation - WoS: 1Citation - Scopus: 2A Pilot Study of a Novel Fixation Technique for Fixation of Comminuted Patellar Fractures: Arthroscopic-Controlled Reduction and Circular External Fixation(Georg Thieme verlag Kg, 2020) Neyisci, Cagri; Erdem, Yusuf; Kilic, Erden; Arsenishvili, Arsen; Kurklu, MustafaPatella fractures represent for 0.5 to 1.5% of all bony injuries in adults. Open reduction and the modified tension-band technique is the most common surgical technique used for patellar fractures. The purpose of this study is to present the outcomes of 26 comminuted patellar fractures treated with circular external fixator (CEF) under arthroscopic control and discuss its potential advantages over conventional surgical methods. This retrospective study included 26 patients who had closed comminuted patellar fractures and treated by CEF under arthroscopic control between January 2002 and March 2016. All patients treated with this technique were involved to the study as a consecutive series. Patients with noncomminuted transverse fractures were excluded, because they were treated with a different technique. Of the 26 patients 22 were male, 4 were female with the mean age of 33.5 years (range, 16-56 years). Patients were followed for 20 to 28 months (mean, 22 months). The mean time to union and the duration of fixation with the CEF ring was 12 weeks (range, 6-15 weeks). The mean Lysholm's score was 45 (range, 35-58) at the 10th postoperative day, which increased to 51 (range, 40-68) at the end of the first postoperative month and increased to 95 (range, 90-100) 1 month after CEF ring removal. Minor pin tract infection by pin-skin irritation was observed in nine patients. In one patient, refracture occurred due to a fall 19 days after CEF removal. CEF appears to be a safe and effective treatment for comminuted patellar fractures with a high union rate and minimal complications. It is safe and effective, as it allows short hospital stay and avoids a second surgery for removal of the instrument. Early rehabilitation with full weight-bearing promotes rapid recovery and quick return to work. Patients do not have a large unaesthetic scar on the anterior of the knee.Article Citation - WoS: 37Citation - Scopus: 59Career Abandonment Intentions among Software Workers(Wiley, 2014) Colomo-Palacios, Ricardo; Casado-Lumbreras, Cristina; Misra, Sanjay; Soto-Acosta, PedroWithin the software development industry, human resources have been recognized as one of the most decisive and scarce resources. Today, the retention of skilled IT (information technology) personnel is a major issue for employers and recruiters as well, since IT career abandonment is a common practice and means not only the loss of personnel, knowledge, and skills, but also the loss of business opportunities. This article seeks to discover the main motivations young practitioners abandon the software career. To achieve this objective, two studies were conducted. The first study was qualitative (performed through semistructured interviews) and intended to discover the main variables affecting software career abandonment. The second study was quantitative, consisting of a Web-based survey developed from the output of the first study and administered to a sample of 148 IT practitioners. Results show that work-related, psychological, and emotional variable are the most relevant group of variables explaining IT career abandonment. More specifically, the three most important variables that motivate employees to abandon the career are effort-reward imbalance, perceived workload, and emotional exhaustion. In contrast, variables such as politics and infighting, uncool work, and insufficient resources influence to a lesser extent the decision to leave the career.

Artificial neural networks (ANNs) are used after data segmentation and classification, where the designed model register records into two class sets, that is, the training and testing sets. ANN predicts new customer behavior from previously observed customer behavior after executing the process of learning from existing data. This article proposes an ANN model, which is developed using a six-step procedure. The back-propagation algorithm is used to train the ANN by adjusting its weights to minimize the difference between the current ANN output and the desired output. An evaluation process is conducted to determine whether the ANN has learned how to perform. The training process is halted periodically, and its performance is tested until an acceptable result is obtained. The principles underlying detection software are grounded in classical statistical decision theory.Article The Relationship between Perinatal Grief and Spiritual Well-Being in Women Experiencing Termination due to Fetal Anomaly in Türkiye(Springer, 2025) Sari, Tugba; Gemicioglu, Sirin HarkinPregnancy termination is a significant event in women's lives and can be considered a traumatic experience that can assess grief reactions. Couples who accept the decision to have a medical termination due to fetal anomaly face not only anxiety and feelings of loss, but also difficulties adapting to and coping with the termination process. This study aims to examine the relationship between perinatal grief and spiritual well-being in women who experience termination due to fetal anomaly. The study sample consisted of 256 women who had undergone termination during pregnancy. Data were analyzed using descriptive statistics (percentage, mean, standard deviation), the Mann-Whitney U test for independent samples, the Kruskal-Wallis test, Spearman correlation, and multiple linear regression analyses. The participants' mean score on the Perinatal Grief Scale was 112.87 +/- 15.04. The spiritual well-being scale subscale scores were 56.13 +/- 8.69 for the transcendence subscale, 25.27 +/- 2.94 for the harmony with nature subscale, and 26.58 +/- 3.18 for the anomie subscale. The correlation between the mean scores of the scales indicated that perinatal grief level was positively and significantly related to both the transcendence (r = 0.454; p < .001) and harmony with nature (r = 0.571; p < .001) subscales, while there was a strong negative correlation between perinatal grief and the anomie subscale (r = -0.762; p < .001). In conclusion, the study results indicate that perinatal grief is significantly related to various dimensions of spiritual well-being. These findings support the idea that supporting spiritual well-being in individuals experiencing perinatal grief can strengthen psychosocial adjustment.Article Citation - WoS: 2Citation - Scopus: 2How Much Similarity Is Good? the Effect of Similarity and Crowding on Place Satisfaction(Routledge Journals, Taylor & Francis Ltd, 2024) Kucukergin, Kemal Gurkan; Koc, BurcuThe relationship between perceived similarity, crowdedness and tourists' evaluations of their experience has been largely neglected by research into the destination social servicescape. This study therefore examines this relationship to fill the gap in the literature. Data were collected from 282 tourists in Pamukkale, Turkey. PLS-SEM and fsQCA were combined to identify the symmetric and asymmetric effects of the destination social servicescape. The PLS-SEM results showed that demographic similarity significantly increased place satisfaction, whereas psychographic similarity and perceived crowdedness had no effect. The study also used fsQCA to investigate how crowdedness and similarity predict place satisfaction in combination with income, age, education, and gender. The analysis identified five different models of place satisfaction by combining different demographic factors.
