Öğe Üniversite kütüphanecilerinin yapay zeka algıları, kütüphanelerde uygulama alanları ve geleceği(ÜNAK, 2024) Çuhadar, Sami; Mert, Selma; Gezer, Çağatay; Helvacıoğlu, Ece; Arus, Oya; Açıkalın, CansuGünümüzde kütüphaneler, değişen teknoloji ve yeniliklerden etkilenen kurumlar arasında yer almaktadır. Yapay zeka teknolojilerinin popüler hale gelmesi, kütüphane hizmetlerini de dönüştürmeye başlamıştır. Bu araştırmada, Türkiye’deki üniversite kütüphanelerinin yapay zeka teknoloji ve uygulamalarının gelişim sürecinde yapmış olduğu ve yapmayı planladığı düzenlemeleri tespit etmek ve ilgili döneme özel geliştirdikleri hizmetleri belirlemek amacıyla bir anket uygulanmıştır. Anket, Türkiye’deki 208 üniversite kütüphanesinden 111 üniversite kütüphanesi yöneticisinin katılımıyla gerçekleştirilmiştir. Verilerin analizi ile üniversite kütüphanelerinin yapay zeka teknolojileri ve uygulamaları hakkındaki durumu, bilgi ve farkındalık düzeyleri belirlenmiş, eksik ve zayıf yönlerin geliştirilmesine yönelik önlemler ve öneriler sunulmuştur. İlgili araştırma, yapay zeka konusunda Türkiye’de üniversite kütüphanesi yöneticilerinden görüş ve öneri alarak gerçekleştirilen ilk ve en kapsamlı çalışmadır. Araştırma bulguları, üniversite kütüphanelerinin ChatGPT, Gemini, Grammarly vb. yapay zeka uygulamalarını belirli düzeyde kullandıklarını ancak yapay zeka ile ilgili kurumsal politika geliştirme, personele yetkinlik kazandırma ve planlama konularında ihtiyaçlarının olduğunu ortaya çıkarmıştır.Öğe The use of low level laser therapy in conjunction with diode laser-assisted and conventional vestibuloplasty: Comparison of wound healing and vestibular depth gain(Elsevier, 2023) Karaş, Mert; Günpınar, ŞadiyeBackground: The aim of this study is to compare wound healing and vestibular depth gain in individuals undergoing vestibule deepening surgery using diode laser and conventional technique and to further investigate the possible wound healing effect of low-level laser therapy (LLLT).Material and Methods: 52 systemically healthy individuals with insufficient vestibular depth in the region of teeth 33-43 in the lower jaw were included. Following nonsurgical periodontal treatment, patients were divided into four groups as follows: a) diode laser (L); b) diode laser + LLLT; c) conventional surgery and d) conventional surgery + LLLT. Vestibular depth and horizontal wound size measurements of the individuals were recorded using digital calipers. Reepithelization was evaluated via an image analysis program.Results: Vestibular depth measurements were found to be higher in the conventional surgery groups compared to that of diode laser groups after the operation, while the results were not statistically different between groups (p >0.05). Reepithelization area did not differ between groups in the evaluated time periods (p >0,05). On the other hand, horizontal wound shrinkage was significantly higher in the conventional surgery group than that of diode laser.Conclusions: Within the limits of this study, both methods yielded in vestibule depth gain. On the other hand, LLLT did not have an additional positive effect on mucosal wound healing. As a clinical relevance, the results are valuable for clinicians in terms of showing that suturing of the mucosal flap formed following vestibule deepening should not be necessary in laser assisted surgery for attaining more vestibule depth.(c) 2023 Elsevier Masson SAS.

Evidence from the RALS-CIPS Test(Economics Bulletin, 2021) Konat, Gokhan; Zeren, FatmaThe purpose of this study is to propose a new residual-based unit root test and then apply it to examine the stationarity of gross domestic product (GDP) for EU membership countries. For this purpose, the CIPS test proposed by Pesaran (2007) has been extended to a structure that takes into account the knowledge of the non-normally distributed residuals. For this, the residual augmented least squares (RALS) estimators proposed by Im and Schmidt (2008) were included in the CIPS test. The second and third moments of the error terms are added to the cross-sectionally augmented ADF (CADF) regression that constitutes the CIPS test process. When calibrated under the behavior of the residues non-normally distributed residuals during the data generation process, it is seen that the panel unit root test specific to the series in which the residuals are not normally distributed has higher power and more appropriate size than CIPS test. According to the results of empirical analysis, it was concluded that the CIPS test was stationary only at the 10% level, while according to the RALS-CIPS test it was concluded that it was stationary at the 1% significance level. It can be interpreted that the RALS-CIPS test is stronger because it used additional information consisting of residual moments. The test offers a simple way to have good size and power properties for non-normal errors.Öğe Laboratory findings in acute bacterial meningitis and acute viral encephalitis(New Zealand Medical Assoc, 2024) Gozdas, Hasan Tahsin; Dogan, AhmetÖğe A Sample Lesson Study with Pre-School Teachers: Dialogic Story Reading Bags(Alberta Journal Educ Research, 2020) Cengiz, Guluzar Sule TepetasThe Lesson Study is a professional development model that places teachers at the center of practice and is used in the professional development of teachers who are currently in teacher training or currently in service. In Turkey, the professional development of teachers from various branches is also supported by using this model. However, no previous studies have been found on the use of this model with pre-school teachers. This study was carried out to support and improve the quality of teachers' picture story reading activities by means of lesson study and therefore support the language and early literacy skills of children. Mixed method design was used in the study by utilizing convergent parallel mixed method design. The study group consisted of 14 teachers employed at two independent kindergartens in Bolu city center and 223 children attending these schools during the 2017-2018 academic year. After obtaining all qualitative and quantitative data, statistical analyses were conducted on the quantitative data and content analysis was performed on the qualitative data. As a result of the study, we determined that dialogic reading bags that are developed through the Lesson Study model support children's language development and early literacy skills. In addition, we determined that the Lesson Study model had a positive impact on pre-school teachers' professional development.Öğe Mosaic ring chromosome 6 and clinical significance in resistant epilepsy(Turkish Pediatrics Assoc, 2012) Ocak, Zeynep; Goksugur, Sevil Bilir; Kocaman, Ertugrul MevlutÖğe Coronary Slow Flow COMMENT(Aves, 2022) Izgi, Ibrahim AkinÖğe Comparison of Infrared Tympanic Thermometer with Non-Contact Infrared Thermometer(Aves Yayincilik, Ibrahim Kara, 2014) Ilçe, ArzuÖğe CONTRIBUTION TO THE OSTRACODA (CRUSTACEA) FAUNA OF THE KARSTIC REGION OF TEXAS WITH THE DESCRIPTION OF A NEW SPECIES(Natl Speleological Soc, 2023) Kulkoyluoglu, Okan; Tuncer, AlaettinA total of 27 ostracod taxa were collected from 1995 to 2017 from 61 aquatic bodies in the karstic region of Texas (USA) and 1 in Mexico, including from caves, springs, spring-fed pools, and springs/drips in karstic rock-shelters. Among these taxa, Dolerocypris reyesi sp. nov. is a new species collected from a shallow pool connected to the springs above a rock-shelter. Three species (Penthesilenula aotearoa, P. incae, and Vestalenula marmonieri) are reported for the first time from North America. In addition, Typhlocypris cf. prespica and 4 taxa (Microdarwinula zimmeri, Cypridopsis cf. herpestica, Pseudocandona cf. parallela, P. cf. pratensis) are new records of ostracod fauna of the US and Texas, respectively. The phylogenetic results based on 31 taxa and 30 morphological characters revealed 4 subgroups belonging to 6 main clustering groups within the family Darwinulidae. Including the new species reported here, the total number of non-marine ostracods in Texas is increased to 115 species. The results indicate that the total number of species is far below the true diversity and richness of the state.Öğe Relation of neutrophil/lymphocyte ratio with the presence and extent of coronary artery ectasia(Turkish Soc Cardiology, 2013) Ayhan, Selim; Ozturk, Serkan; Erdem, Alim; Ozlu, Mehmet Fatih; Ozyasar, Mehmet; Erdem, Kemalettin; Yazici, MehmetObjectives: It has been shown that the neutrophil to lymphocyte ratio (N/L ratio) is associated with cardiovascular events and mortality. In this study, we investigated the N/L ratio in patients with coronary artery ectasia (CAE). Study design: Fifty patients (29 men, 21 women; mean age, 51.1+/-7.1 years) diagnosed as CAE using coronary angiography were included in the study. The control group consisted of 28 patients (16 men, 12 women; mean age, 49.5+/-9.4 years) who had normal coronary arteries as determined by coronary angiography. Baseline characteristics were recorded. The number of ectatic segments was noted. Hematologic parameters were measured and the N/L ratio was calculated. Results: The N/L ratio was significantly higher in the CAE group compared with the control group (median [25-75% percentile] 2.2 [1.6-3.0] vs. 1.8 [1.4-2.0], p=0.014, respectively). The Spearman correlation analysis demonstrated that the N/L ratio positivelyÖğe An Unusual Intrathoracic Mass: Lipoma(Derman Medical Publ, 2013) Karapolat, Sami; Dost, Burhan; Kilicgun, AliÖğe Should we administer postexposure rabies prophylaxis to a rabid human?(Inst Nacional Salud Publica, 2024) Tahsin-Gozdas, HasanÖğe Determination of the Most Convenient Polyester Thread Supplier in Upholstery Velvet Production by Multi Criteria Decision Making Methods: A Case from Turkey(Soc Fiber Science Technology, 2022) Arslan, Hakan Murat; Ata, Serhat; Mutlu, Hakan TahiriUpholstery velvet manufacturers choose polyester thread types to get optimum profit by using scientific methods. The matter of determining the most convenient polyester thread supplier might be considered as a decision problem. In this study, the issue of determining the most suitable polyester thread supplier of upholstery velvet manufacturer was analyzed by MACBETH-PROMETHEE Hybrid method. Authorities of relevant businesses were chosen as decision makers. Criteria and alternatives were determined by reviewing literature regarding decision makers. The weights of criteria were evaluated by MACBETH method, however, the priority order of alternatives were evaluated separately both MACBETH and PROMETHEE methods. The fit of analyses practiced by two separate multi criteria decision making methods was tested by Spearman Rank Correlation Analysis. As a result of analyses conducted hybrid method, types of brands and threads were determined. The most basic raw material requirement of enterprises that are upholstery velvet producers is polyester thread. If thread is procured using the model of the study, polyester thread will be purchased at both the most affordable price and the desired quality. Findings were shared with authorities of relevant business.Öğe A Proposal to Develop a New Classification for Pulp Chamber Anatomy(Kare Publ, 2024) Ahmed, Hany Mohamed Aly; Keles, Ali; Wolf, Thomas Gerhard; Rossi-Fedele, Giampiero; Dummer, Paul Michael HowellÖğe The relationship between tumor budding and survival in colorectal carcinomas(Assoc Medica Brasileira, 2020) Aktas, GulaliÖğe THYROID-RELATED FACTORS THAT INFLUENCE PREOPERATIVE LOCALIZATION OF PARATHYROID ADENOMAS(Amer Assoc Clinical Endocrinologists, 2012) Isik, Serhat; Akbaba, Gulhan; Berker, Dilek; Tutuncu, Yasemin Ates; Ozuguz, Ufuk; Aydin, Yusuf; Peksoy, IrfanObjective: To evaluate the effect that thyroid-related factors have on the preoperative localization of parathyroid adenomas. Methods: This retrospective study included adult patients who were referred for further evaluation of primary hyperparathyroidism between December 2005 and October 2009 at a teaching and research hospital in Turkey. High-frequency ultrasonography and sestamibi scintigraphy (MIBI) were performed in all patients. Surgical procedure involved focal or bilateral exploration on the basis of concordant or discordant imaging studies. Selection of patients for minimally invasive parathyroidectomy was made based on the presence or absence of a single parathyroid adenoma detected by both ultrasonography and MIBI scan. Patients with negative or discordant imaging studies and a concomitant thyroid nodule underwent bilateral neck exploration. Results: Two hundred and forty-eight patients with primary hyperparathyroidism who underwent parathyroidectomy were included in the study. Parathyroid gland abnormalities were successfully detected preoperatively by ultrasonography in 231 patients and by MIBI scan in 152 patients. When used together, ultrasonography and MIBI scan were unsuccessful in detecting an abnormality in 11 cases. MIBI scan visualized a lesion in 6 cases that remained undiagnosed by ultrasonography. Fifty-six of 85 patients with lesions detected by ultrasonography, but not by MIBI scan, had thyroid nodules. The frequency of thyroid nodules was higher in the 96 patients in whom a MIBI scan could visualize a parathyroid lesion than in the 152 patients in whom MIBI scan was successful (P = .004). No difference was observed regarding ipsilateral thyroid lobe involvement or nodule volume. Parathyroid adenomas were significantly smaller in patients with negative MIBI scans (P<.001). Conclusion: Our results suggest that ultrasonography is more sensitive than MIBI scan in the detection of parathyroid adenomas, particularly in the presence of small parathyroid adenomas or other thyroid related-factors. (Endocr Pract. 2012;18:26-33)Öğe Entoptic Phenomenon Following Pars Plana Vitrectomy Caused by Retained Preretinal Gel(Slack Inc, 2009) Yavuz, Guelderen Aktan; Uenver, Yaprak Banu; Sinclair, Stephen H.A patient who underwent pars plana vitrectomy for vitreous floaters is described. At the time of surgery, the posterior hyalold was avulsed and stripped from the posterior retinal surface. Postoperatively, the patient described filamentous and sea-fan entoptic phenomena scattered throughout the periaxial vision that were in focus, attached, and waving with movement that was counter to the direction of gaze pursuit and demonstrated after movement. The authors believe these structures represent vitreous gel retained at the retinal surface, even though the structures could not be demonstrated by optical coherence tomography or indocyanine green staining at later vitrectomy surgery. This case should raise caution when considering vitrectomy surgery that requires posterior hyalold stripping in patients with good vision.

Kutalmis; Simsek, Huseyin; Abay, FeridunAim: The aim of this study was to evaluate the flexural strength properties of three different aged and nonaged 3D-printed resins built by different 3D printing systems used in dental applications. Materials and Methods: Bars (2 x 2 x 25 mm) were additively fabricated using a 3D printer and different dental crown resins (Saremco Crowntec, Senertek P-Crown V2, and Senertek P-Crown V3) per the manufacturers' recommendations. Each subgroup was divided into aged and nonaged subgroups (n = 10 bars per group). Thermocycling procedures (5 degrees to 55 degrees C; 5,000 cycles) were performed under favorable conditions for the aged subgroups from each material. Flexural strength (MPa) was measured in all samples using a universal test machine. Results: When both aged and nonaged resins are compared, significant differences were found in flexural strength measurements (P <.001). The highest flexural strength was observed in the Saremco Crowntec group, while the lowest flexural strength was observed in the Senertek P Crown V2 group. The flexural strength measurements of Saremco Crowntec and Senertek P Crown V3 displayed no significant difference between their aged and nonaged groups (P >.05), while Senertek P Crown V2 (P =.039) showed significant differences between its aged and nonaged groups. Conclusions: Saremco Crowntec showed the highest flexural strength both in aged and nonaged groups, while Senertek P Crown V2 had the lowest strength. The artificial aging process decreased flexural strength values in all 3D-printed resin groups.Öğe Reply to Letter: HbA1c/C-Peptide Ratio is a Potential Biomarker Used to Predict No-Reflow Phenomenon in Patients With ST-Elevation Myocardial Infarction(Sage Publications Inc, 2024) Toprak, Kenan; Kaplangoray, Mustafa; Inanir, Mehmet; Dursun, Ayten; Tascanov, Mustafa Begenc; Altiparmak, Ibrahim Halil; Bicer, Asuman
