Article Citation - WoS: 3Citation - Scopus: 3Modeling and Measurement of Human Body Blockage Loss at 28 Ghz(Taylor & Francis Ltd, 2023) Benzaghta, Mohamed; Gokdogan, Bengisu Yalcinkaya; Coruk, Remziye Busra; Kara, AliMillimeter-wave (mm-Wave) spectrum is an essential enabler to the fifth generation (5G) wireless technology. Humans are one of the most noticeable blockers that cause temporal variation in indoor radio channels. This paper presents human blockage measurements at 28 GHz, with several humans of different sizes. The effect of the crossing orientations of the human bodies is investigated for three different transmitter heights. A human blockage model based on the Fresnel diffraction scheme is shown to be applicable in estimating the human blockage loss in indoor radio links considering various body sizes, different crossing orientations, and different transmitter heights. The findings reported in this paper could help improve indoor radio channel models at 28 GHz bands for 5G technologies considering the presence of human body blockages.Article Citation - WoS: 4Citation - Scopus: 4A Site Survey of Damaged Rc Buildings in Izmir After the Aegean Sea Earthquake on October 30, 2020(Croatian Soc Civil Engineers-hsgi, 2023) Mertol, Halit Cenan; Tunc, Gokhan; Akis, TolgaAn earthquake with a magnitude of Mw = 6.6 and a depth of approximately 16.5 km occurred on 30 October 2020 off the cost of Samos, a Greek island 35 km southwest of Seferihisar, a town in Izmir. The earthquake caused several collapses and severe structural damage in approximately 6,000 buildings, specifically in the Bayrakli District in Izmir Bay. This paper presents the observations and findings of a technical team that visited the earthquake -affected areas immediately after the earthquake. Eleven partially or fully collapsed and several severely damaged reinforced concrete buildings were investigated. Based on the site investigations, we observed that almost all of the collapsed or severely damaged reinforced concrete buildings in the region were built between 1975 and 2000. Site observations also confirmed that the construction of these collapsed or damaged buildings did not conform to the requirements outlined in the Turkish Earthquake Codes used at the time. The failures and severe damage to buildings in earthquake-affected areas are primarily related to inadequate reinforcement configuration, poor material quality, the absence of geotechnical studies, and framing problems related to their lateral load-carrying systems. Therefore, it is recommended that all the buildings located in and around Izmir Bay, particularly those built between 1975 and 2000, be structurally evaluated to prevent any further loss of life and property during future earthquakes.Article Citation - WoS: 2Citation - Scopus: 2Enhancing Classification Modeling Through Feature Selection and Smoothness: a Conic-Fused Lasso Approach Integrated With Mean Shift Outlier Modelling(Amer inst Mathematical Sciences-aims, 2025) Yerlikaya-Ozkurt, Fatma; Taylan, PakizeOutlier detection and variable selection are among main objectives of statistical analysis. In our study, we address the outlier problem for classification by using the Mean Shift Outlier Model (CLMSOM). Since the MSOM has more coefficients than the linear regression model, the complexity of the model MSOM is high. Therefore, we consider feature selection for MSOM by using fused Lasso (FLasso), which is beneficial and helpful in the cases where the number of explanatory variables or features is greater than the sample size. FLasso is penalizing both the coefficients and their successive differences by the L-1-norm, and it allows sparsity for both of them, while Lasso only allows the coefficients by considering a nonsmooth optimization problem. In this study, we take into account Iterated Ridge approximation which enables us to use a smooth optimization for FLasso problem. Generated smooth optimization problem is solved by using one of continuous optimization techniques called Conic Quadratic Programming (CQP), which is enabling the utilization of interior point methods. The newly developed method is called Conic FLasso for classification by MSOM (C-FLasso-CLMSOM) and is applied to real world data set to show its performance.Article Effectiveness of Game-Based Teaching Method on Nursing Students' Knowledge of Enhanced Recovery After Surgery (ERAS)(Dubai Iranian Hosp, 2024) Abumettleq, Ibrahim S. S.; Bayraktar, Nurhan; Dikmen, Burcu ToturBackground and Objectives: The technology was created by humans; it is also innovative when teachers use it in the classroom. Teachers can now use media in a variety of ways to accommodate different learning styles thanks to new technologies, including animation, live video, gaming, and more. The study aimed to assess how well the game-based learning approach enhanced the students' understanding of Enhanced Recovery After Surgery (ERAS). Methods: This study was structured utilizing a quasi-experimental design applied with pre-and post-test assessments. The study was conducted by a nursing faculty at the "[blinded for review]".Using the census method, the students were randomly assigned to either the experimental or control groups (each consisting of 80 and 40 players). On March 18, 2022, the study was conducted at a North Cyprus nursing faculty. Both computers and phones can use the Kahoot app, which is used to play the game. Results: The study conclusions demonstrated that following the instructional intervention using game-based learning, students' performance improved in terms of the overall mean scores of all Enhanced Recovery After Surgery (ERAS). Conclusion: Our results generally demonstrate that game-based learning improves the standard of instruction for the students. However, our results show that the game-based teaching method enhances nursing students' comprehension of Enhanced Recovery After Surgery (ERAS), and the method could be useful in developing lesson plans for nursing education and nursing schools.Article The End of a Fairy Tale, The Start of a New Era? The Eu and China in The Western Balkans(Turkish Policy Quarterly, 2024) Yilmaz, GozdeThe Western Balkans have been transformed into authoritarian regimes in the last decade, despite the EUs' engagement with the region through its enlargement policy. However, prioritizing stability over democracy, the EU lost its chance to transform the Western Balkan countries into democratic entities. In the end, the EU opened a way in for the external actors to the Western Balkan countries and China has entered the scene by increasing engagement with the region. The leaders of the authoritarian regimes in the Western Balkans adopted a pragmatic approach in their relations with China. They used the Chinese card to proceed with their relations with the EU and to gather financial means to legitimize and consolidate their regimes.Article Effect of 25(OH)D Supplementation on Adipokines and Advanced Glycation End Products in Experimental Type 2 Diabetic and Obesity Rat Model(Univ Karachi, 2025) Toprak, Cigdem; Yigitaslan, Semra; Aykanat, Ezgi Bektur; Sirmagul, Basar; Sahinturk, VarolDiabetes mellitus is a global health problem and vitamin D deficiency is thougt to be a reasonal factor for development of diabetes. Our aim is to investigate among vitamin D levels and blood glucose, insulin resistance, adiponectin, apelin, tumor necrosis factor-alpha (TNF-alpha), interleukin-6 (IL-6), oxidative stress index (OSI) levels and advanced glycation end products (AGEs) formation in modeled obesity and type 2 diabetes mellitus (T2DM) rats. During the 14-week experiment; 1-Control group was fed standart diet-(12 % of calories of fat), 2-Diabetes group was fed high fat diet (HFD)-at the 4th week Streptozotocin (STZ) (35 mg/kg) was injected, 3-Diabetes/vitamin D group was fed HFD-at the 4th week STZ was injected-between 4th-14th week vitamin D supplement was administered, 4-Obesity group was fed HFD-(40% of calories as fat), 5-Obesity/vitamin D group was fed HFD-between 4th-14th week vitamin D supplement was administered. At 14th week, biochemical parameters, adipokine concentrations, kidney tissue cytokine levels, liver tissue oxidative stress index parameters were measured in serum and tissue using commercial ELISA kits, H&E (hematoxylin & Eosin) staining of kidney, heart, liver, coronary artery, renal artery tissues and immunohistochemical staining of kidney tissues were performed. It was concluded that vitamin D can alleviate glucose parameters and lipid parameters in type 2 diabetic and obesity modeled rats and we think it may be useful adjuvant agent in obesity and T2DM treatment.Article Citation - WoS: 3The relationship between dental caries, dietary intake and body composition in school-age children(Springer, 2024) Ozel, Irem Cagla; Unverdi, Gizem Erbas; Eymirli, Pinar Serdar; Ayhan, Nurcan YabanciObjective The aim of this study is to evaluate the relationship between dental caries, food intake, and body composition in school-age children. Methods The study was conducted on 210 children, 105 boys and 105 girls, aged 6-12 years, without mental and/or physical disorders. Oral examinations of the children were performed by paediatric dentists and DMFT-DMFS and dmft-dmfs values were recorded. A detailed food frequency questionnaire was applied to determine the consumption frequency of dairy products and sugar-added foods. Children's height, waist and hip circumference measurements were taken by the researcher; body weight and body composition were evaluated with a Tanita body analyzer. Results The DMFS value of children who consumed white cheese daily is lower than children who did not (p < 0.05). The DMFT and DMFS values were found to be higher in children who consumed sweets, biscuits, and spreadable chocolate daily compared to children who did not (p < 0.05). Body weight and waist circumference are positively correlated with DMFT and negatively correlated with dmft. BMI is positively correlated with DMFT and negatively correlated with dmft (p < 0.05). In binary logistic regression, it was found that maternal education level, frequency of added sugar intake and body fat ratio were predictors of the presence of caries. Conclusion In this study, dental caries was associated with food consumption and body mass index. In children, consumption of sugary foods should be reduced and consumption of dairy products should be increased.Article The Relationship Between Concentric and Isometric Strength of Knee Flexor and Extensor Muscles and Postural Stability in Mild Stage Multiple Sclerosis Patients(Taylor & Francis Ltd, 2025) Yilmaz, Seval; Unluer, Nezehat OzgulBackground Multiple sclerosis (MS) affects muscle strength and postural stability. However, the relationship between concentric and isometric strength of knee flexors and extensors and postural stability in mild stage MS is not well known. The aim of the study was to examine the relationship between concentric and isometric strength of knee flexors and extensors and postural stability in mild stage MS patients. Materials and Methods The study included 21 mild-stage MS patients with an EDSS score of 4 or less and 21 healthy controls. The concentric and isometric strength of knee flexors and extensors was measured with the Biodex System 4 Dynamometer, and postural stability with the Biodex Balance System under eyes-open and eyes-closed conditions on a rigid surface. Results Mild-stage MS patients had reduced concentric strength of knee extensors and flexors and increased postural sway compared with healthy controls (p < 0.05). Isometric strength of knee extensors and flexors in mild stage MS patients were similar to healthy controls (p > 0.05). There was a moderate positive correlation between concentric strength of knee extensors and flexors and isometric strength of knee flexors and open-eye postural stability indexes in mild stage multiple sclerosis patients (p < 0.05). Conclusions While isometric strength of knee extensors and flexors was preserved, concentric strength of knee extensors and flexors was decreased, and postural stability was adversely affected in mild stage MS patients. The increase in the strength of the knee muscles was associated with an increase in their postural sway in mild stage MS patients.Article Citation - WoS: 5Citation - Scopus: 6Balance and Gait in Individuals With Diabetic Peripheral Neuropathy(Taylor & Francis Ltd, 2024) Korkusuz, Suleyman; Seckinogullari, Busra; Yuruk, Zeliha Ozlem; Ulug, Naime; Kibar, SibelBackground: Diabetic Peripheral Neuropathy (DPN) causes various physical problems such as the increased risk of falling, loss of balance and coordination while standing or walking, susceptibility to injuries due to sensory loss.Aims: The aim of the study was to evaluate and compare the effects of neuropathic pain (NP) in individuals with DPN on balance and gait.Methods: This prospective controlled study was conducted on 42 adults aged between 40-65 years. The participants were divided into three groups; individuals with DPN and NP (DPN+NP/n = 14), individuals with DPN without NP (DPN-NP/n = 14), and the control group (n = 14), respectively. The Force Plate system and Core Balance System measured static and dynamic postural balance and stability limits. Gait and dynamic plantar pressure distribution analyses were performed with a computerized gait evaluation system.Results: The score of LANSS, and VAS during gait were higher in DPN+NP group than in DPN-NP (p < 0.05). No significant difference was observed between the groups in balance parameters (p > 0.05). The right-left heel maximum forces were lower in both groups with DPN compared to the control group (p < 0.05). In terms of spatiotemporal parameters of the gait, there was a difference between the groups only in step width and left single support line parameters (p < 0.05).Conclusions: The results of this study indicate that the individuals with DPN have an increased step width, their left single support line was shortened, and the maximum force on the heel decreased. The NP did not cause any change in balance and gait parameters.
