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 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.

A secondary aim was to compare the findings with a matched control group exhibiting normal occlusion (CG) using cone beam computed tomography (CBCT).Material and methods: The study groups consisted of (1) 30 patients (Mean age: 14.49 & PLUSMN; 1.91years) with a UCB, (2) 29 patients (Mean age: 14.57 & PLUSMN; 1.84 years) with a BCB, and (3) 36 patients (Mean age: 14.24 & PLUSMN; 2.42 years) as a matched control group (CG). Condylar, ramal, condylar-plus-ramal height and index measurements were performed using CBCT images following the method of Habets et al. A paired t-test was performed for side comparison in each group. One-way ANOVA (Analysis of Variance) was used to determine statistically-significant differences between the groups for asymmetry index measurements and Tukey's HSD test was employed for individual group differences.Results: There was no statistically significant difference in condylar height (CH), ramal height (RH), and condylar plus ramal height (CH + RH) measurements between the right and left sides of the UCB group and CG, except for the RH in the BCB group (p = 0.045). Tukey's HSD test showed that the ramal asymmetry index (RAI) and the condylar plus the ramal asymmetry index (CRAI) were statistically significantly different between the UCB and BCB groups (p = 0.035 and p = 0.015, respectively).Conclusions: Although the condylar asymmetry index (CAI) values were found to be high in the groups of UCB (13.84 & PLUSMN; 11.33), BCB (9.38 & PLUSMN; 8.56), and CG (10.58 & PLUSMN; 9.48), the comparisons amongst the groups were not statistically significant. The asymmetry between the UCB and BCB groups was observed for RAI and CRAI values, rather than CAI values.Öğe Should we administer postexposure rabies prophylaxis to a rabid human?(Inst Nacional Salud Publica, 2024) Gözdaş, Hasan TahsinThe incubation period of ra-bies is approximately one to three months. Rabies is almost always fatal when the virus reaches the central nervous system (CNS). Postexposure prophylaxis should be administered as soon as possible after the exposure. It is of no benefit when the CNS symptoms appear which is indicative of the virus arriving the CNS.2,3 Their patient showed CNS symptoms and signs suggestive of clinical rabies, then he was administered rabies im-munoglobulin and a Vero-cell rabies vaccine. He died despite medical supportÖğe 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 Behcet's disease without neurological manifestations(Tohoku Univ Medical Press, 2005) Keçeci, HulusiÖğe Subjective symptoms of RME patients treated with three different screw activation protocols: A randomised clinical trial(Sciendo, 2012) Halıcıoğlu, Koray; Kiki, Ali; Yavuz, İbrahimAims: The purpose of the present study was to evaluate the subjective symptoms of patients during the active phase of rapid maxillary expansion (RME) treatment, and further, to assess the differences between three different RME activation protocols.Materials and methods: The clinical sample consisted of 60 patients (mean age 13.5 years) with maxillary transverse deficiency requiring expansion. The subjects were randomly divided into three groups on which different expansion protocols were performed. An evaluation of the subjective symptoms was carried out by a Numerical Rating Scale (NRS). The patients completed questionnaires after the first, fifth, tenth, twentieth and final activations. A Shapiro-Wilk test was applied to evaluate homogenity; a Kruskall Wallis test was performed for gender-related differences and to compare the different activation schedules. The Wilcoxon test was used to compare the activations at the various time intervals.Results: No gender-related differences were found. Ninety-eight percent of the patients reported pain during RME. There were no specific differences between groups except for the pain perceived at the twentieth activation. In all groups, pain, the sensation of pressure and its duration were highest at the fifth activation. Subjective symptoms tended to decrease after the fifth and tenth activations. Headache and dizziness were minimal.Conclusion: Different activation protocols did not appear to alter subjective symptoms encountered during RME. The majority of the patients undergoing RME suffered pain and pressure sensations especially after the fifth activation.Öğe A proposal to develop a new classification for pulp chamber anatomy(Kare Publ, 2024) Ahmed, Hany Mohamed Aly; Keleş, Ali; Wolf, Thomas Gerhard; Rossi-Fedele, Giampiero; Dummer, Paul Michael HowellIt is well known that the human dentition varies considerably in terms of the anatomy of roots, pulp chambers and root canals (1–5). This variation is obvious between tooth types, individuals and population groups and is influenced by age, caries, tooth surface loss, developmental defects, anomalies, trauma and a range of other conditions (2–5). The pulp chamber is defined as the portion of the pulp space within (or extending just apical) the anatomic crown of the tooth that contains the coronal pulp tissue and consists of the pulp horn(s) and body leading to the orifice(s) of the root canal(s) (6, 7). The shape, size and position of the chamber originally reflects the anatomy of the crown (8), but is particularly subject to morphological changes as a result of age and as a defensive mechanism against irritationÖğe The relationship between tumor budding and survival in colorectal carcinomas(Assoc Medica Brasileira, 2020) Aktaş, GülaliI have reviewed the article entitled ‘The Relation ship Between Tumor Budding and Survival in Colorectal Carcinomas’, by Peltek Ozer et al.1 for the Revista da Associação Médica Brasileira The authors inves tigated tumor budding (TB) by its new definition and reported that TB was an independent prognostic factor in colorectal carcinoma, which was also associated with perineural invasion, lymph node metastasis, lymphovascular invasion, and survival. The association with TB and perineural invasion has been reported in only a few studies; thus, Peltek Ozer et al.’s1 study made a significant contribution to the literature.Öğe Reflection at the interface of theory and practice: An analysis of pre-service english language teachers' written reflections(Edith Cowan Univ, 2011) Yeşilbursa, AmandaThis study was conducted to identify the characteristics of a group of Turkish pre-service English Language teachers' reflective writing. A mixed method approach was taken in the analysis of their written reflections on a video-recorded microteaching experience at the end of a campus-based methodology course. First, qualitative analysis of the written reflections revealed the modes and themes of reflection. Second, the crosstabulations of the emerging reflective and thematic categories were calculated to investigate how each category interacted. The analyses revealed that while most of the reflection was descriptive and focused on the self, some of the participants engaged in reflection that showed a search for reasons behind and alternatives to their practice. Some also referred to past and hypothetical future experiences. This study contributes to the knowledge base on the reflective writing of non-native pre-service English Language teachers and emphasises the importance of tapping into reflections early on in pre-service teacher education.
