360 Derece Geri Besleme Yönteminin Uygulanabilirliği :Bir Tugay Örneği
(isarder. 1, 4, 118-131, 2012) Turgut Hakan, Öztoprak Menekşe
Günümüzde insan kaynakları yönetimi sürecinin temel fonksiyonlarından birisi olan bireysel performansların ölçülmesi konusunda 360 derece geri besleme yöntemi; birden çok boyutu dikkate alarak daha objektif sonuçlara ulaşılabilme imkânı vermesi sebebiyle ön plana çıkmaktadır. Türkiye?deki istihdamın büyük bir kısmını karşılayan kamu sektöründe bahse konu yöntemin uygulanabilirliğinin yeterince araştırılmadığı görülmüştür. Bu çalışmada, kamu kurumlarına örnek teşkil edebilecek bir tugayda görev yapan alt ve orta kademe yöneticilerinin performans ölçümüne esas olmak üzere değerlendirme boyutları (amir, denk, astlar, müşteriler, öz değerlendirme) arasında farklılıklar araştırılmış ve geleneksel amir değerlendirmesi ile 360 derece bireysel performans değerlendirme yöntemi arasında karşılaştırmalar yapılmıştır. Değerlendirme boyutları bazında yapılan karşılaştırmalarda sadece iç müşteri boyutunda iki farklı yöntem (Geleneksel amir değerlendirmesi - 360 geri besleme yöntemi) arasında anlamlı farklılıklar tespit edilmiştir. Geleneksel amir değerlendirmesi ile 360 derece geri besleme yöntemi arasında kriterler bazında bazı farklıklara rastlanılmasına rağmen; her iki yöntemin bütün kriterlerinin dahil edildiği genel ortalamalarıyla yapılan karşılaştırmalarda anlamlı bir farklılığa ulaşılamamıştır. Abstract On the subject of measuring individual performances, which considered to be one of the fundamental functions of the human resources management process, 360 Degree Feedback (360 DF) methods preferred for taking into account more than one aspect while providing opportunities in order to achieve more objective results. It?s been thought that the applicability of the above mentioned method is not investigated enough in the public sector where most of the employments take place in Turkey. The purpose of this study is to probe into the applicability of the 360 DF method on low and mid-level managers in a brigade. Within this framework, differences between the raters(manager, subordinate, peer, client, self-evaluation) have been examined and comparisons made between traditional performance appraisal and 360 DF methods. There are meaningful differences only inner client between two different evaluation methods (Traditional manager evalution-360 DF) within evaluation raters. But there aren?t any meaningful differences between traditional performance appraisal and 360 DF methods as whole method.
3D evaluation of the effect of disinfectants on dimensional accuracy and stability of two elastomeric impression materials
(2018) Cinar, Duygu; Soganci, Gokce; Caglar, Alper; Yagiz, Ayberk; 29848853
The aim of this study was to determine and compare the dimensional changes of polyether and vinyl polyether siloxane impression materials under immersion disinfection with two different disinfectants in three time periods. Impressions were obtained from an edentulous master model. Sodium hypochlorite (5.25%) and glutaraldehyde (2%) were used for disinfection and measurements were done 30 min later after making impression before disinfection, after required disinfection period (10 min), and after 24 h storage at room temperature. Impressions were scanned using 3D scanner with 10 microns accuracy and 3D software was used to evaluate the dimensional changes with superimpositioning. Positive and negative deviations were calculated and compared with master model. There was no significant difference between two elastomeric impression materials (p>0.05). It was concluded that dimensional accuracy and stability of two impression materials were excellent and similar.

(2019) Koç, C.; Kamburoglu, K.; Sönmez, G.; Yilmaz, F.; Gulen, O.; Karahan, S.; 30506961
Aim To assess observer performance in detecting endodontic complications using three different cone beam computed tomography (CBCT) units with and without the application of artefact reduction modes. Methodology The study involved 40 freshly extracted human mandibular teeth (n = 10 per group) and divided randomly into four endodontic complication groups. Group 1) Instrument fracture; Group 2) Strip perforation; Group 3) Canal underfilling; and Group 4) Canal overfilling. Images of each tooth were obtained using three different CBCT units offering artefact reduction algorithms: the ProMax 3D Max, the Pax Flex 3D and the Dentri S. Four observers evaluated the images for the presence/absence of the four simulated endodontic complications. Weighted kappa coefficients and intra-class correlation coefficients (ICCs) were calculated to reveal the intra- and inter-observer agreement for each imaging mode, respectively. Receiver operating characteristic (ROC) analysis was used to evaluate the observers' performance. DeLong tests were used to compare the results for each image mode and observer using a significance level of alpha = 0.05. Results In each of the four simulated endodontic complication groups, no significant differences were observed with and without application of artefact reduction for any of the three CBCT units tested. Only two significant differences were detected, and both were between the ProMax 3D Max at low mode AR and ProMax 3D Max without AR: observer 2 in group 1 (P = 0.0001) and observer 4 in group 4 (P = 0.0256). Conclusion For each of the three CBCT units tested, application of artefact reduction for detecting endodontic complications is not recommended as a routine tool.

Anaesthetic Management for Orthotopic Liver Transplantation in A Patient with Glycogen Storage Disease Type Iiia
(2023) Haka, D.; Cekmen, N.; 0000-0001-7448-8203
Glycogen storage disease (GSD) type III is a metabolic disorder caused by a deficiency in amylo-1,6-glucosidase enzyme, which is responsible for the breakdown of the glycogen molecule, resulting in glycogen accumulating in the organs, hypoglycaemia, muscle weakness, liver dysfunction, delayed anaesthetic recovery, excessive surgical bleeding, cardiomyopathy and end-organ dysfunction. This case report presents a child with GSD type IIIa who underwent orthotopic liver transplantation (OLT) with her mother as a donor. A multidisciplinary approach should be provided to optimise the preoperative period and minimise complications in these patients.
Analysis of Probiotic Bacteria Genomes: Comparison of CRISPR/Cas Systems and Spacer Acquisition Diversity
(2021) Ilikkan, Ozge Kahraman; 0000-0001-5843-6868; 35068602; Q-9641-2019
Clustered regularly interspaced short palindromic repeats (CRISPR) and CRISPR-associated (Cas) genes constitute an adaptive (acquired) defense system of bacteria and archaea. Here 72 probiotic bacteria genomes were investigated in terms of the presence of CRISPR/Cas systems and phage/plasmid invaders through spacer analysis. 49 CRISPR/Cas systems were detected within probiotic strains, namely,17 type II-A, 10 type I-C, 8 type I-E, 5 Type I-U (I-G), 4 type III-A, 2 type I-B, 1 type I-A, 1 type IV-B, and 1 type II-C. The predicted target of spacers was determined in 25 strains and consequently, three different spacer and target patterns were revealed. The diversity of CRISPR spacers provides insight and understanding to determine strain-specific invaders of probiotic bacteria as well as their relationships between strains. CRISPR systems were clarified in many studies for genomic characterization. However, recently, endogenous genome editing with CRISPR has provided an approach for various genome editing projects. Thus, in the future, producing strain-specific phage-resistant starter cultures or probiotics by endogenous genome editing methods according to phage/plasmid survey can be utilized for industrial and pharmaceutical applications. Therefore, this study intended a comprehensive investigation of CRISPR systems of probiotic bacteria.
Analysis of the IR-Raman Modes and the Heat Capacity Near the alpha-Inc-beta Transitions in Quartz
(2021) Yurtseven, H.; Gunay, E.; Karacali, H.; Ates, S.
This study gives our analysis for the temperature dependence of the infrared frequency and the integrated intensity of the 695 cm(-1) mode near the alpha-beta transition at 847.5 K and the temperature dependence of the Raman scattering cross section of the 355 cm(-1) mode near the beta-INC (incommensurate) transition which occurs within a small temperature (similar to 1.3 K) interval in relation to the order parameter in quartz. Both analyses are performed according to a power-law formula for the order parameter Q with the critical index beta using the experimental data from the literature. We also analyze the temperature dependence of the heat capacity C p according to the renormalization-group expression including first-order corrections to scaling term close to the alpha-INC-beta transitions in quartz by using the literature data. From our analyses, values of the critical exponent beta for the frequency and the integrated intensity of the 695 cm(-1) infrared mode and for the Raman scattering cross section of the 355 cm(-1) mode as a measure of the order parameter, are extracted. From the analysis of C p , the values of the critical exponent alpha are also extracted. Additionally, by means of scaling relations the critical exponent gamma of the isothermal compressibility kappa T and the renormalized components ( beta R , alpha R and gamma R ) are predicted for the alpha-INC-beta transitions in quartz. Our analyses given here indicate that weakly first-order transition occurs from the alpha phase to the incommensurate (INC) phase, which changes to the nearly second-order transition to the beta phase with increasing temperature in quartz, as also observed experimentally.
Analysis of the treatment costs of HIV/AIDS in Turkey
(2016) Malhan, Simtem; Zengin, Tuba Elbir; Yenilmez, Fatma Betul; Dalgic, Canan; Cerci, Pamir; Oksuz, Ergun; Unal, Serhat; 0000-0002-5723-5965; K-8238-2012
OBJECTIVE: Infection with the human immunodeficiency virus (HIV), the causative agent of acquired immune deficiency syndrome (AIDS), is a major global health problem. Patients with HIV can live normal lives with today's new treatment options. As the treatment is generally successful, the life expectancy of patients infected with HIV is rising. As a result, the economic burden of HIV treatment on health systems is set to increase. According to the Ministry of Health, there were more than 6000 HIV-positive patients in Turkey in 2013. The aim of this study was to determine the direct costs of HIV treatment in Turkey. METHOD: A retrospective data analysis was performed from the reimbursement agency perspective. Data for 252 patients at a university hospital in Ankara from 2001 to 2012 were used for the analysis. The average costs of treatment per HIV patient and the average costs per HIV patient, depending on the state of the patient's health, were calculated. The latter was determined according to the number of CD4 cells/ml, as defined by the CDC's classification system for HIV infection. The cost of treatment was calculated based on published reimbursement prices in 2013, per patient per year. RESULTS: The CD4 values of 25.3%, 29%, and 45.7% of the 252 patients were < 100 cells/mm(3), 100-300 cells/mm(3), and > 300 cells/mm(3), respectively. The treatment costs per patient per year for 2013 for those with CD4 values of < 100 cells/ mm(3), 100-300 cells/mm(3), and > 300+ cells/mm(3) were $ 5,637.04, $ 2,211.54, and $ 2,182.35, respectively. The weighted average of the treatment cost per patient was $ 3,344.64 for 2013. CONCLUSION: This analysis is unique to Turkey and calculates the cost only of HIV treatment in Turkey. Lower CD4 values are associated with higher treatment costs. Appropriate HIV treatment is crucial for controlling CD4 values and lowering the treatment costs of HIV patients. These findings need to be considered by policy makers who may need to focus on HIV.

Antecedents of Nurse Burnout During a Pandemic: Managerial Way Out
(2022) Basar, Ufuk; Dogan, Aysun; Ertugrul, Bekir
The aim of this research is to uncover whether nurses' fear of contracting Coronavirus Disease 2019 (COVID-19) has resulted in stress-related presenteeism and burnout, and whether perceived organisational support is effective in dealing with both nurses' fear of contracting COVID-19 and its undesired consequences. For this purpose, a cross-sectional and descriptive research has been conducted. The data are collected from 513 nurses working in Ankara, Turkey, through a questionnaire survey. Independent samples t-test, one-way analysis of variance test and partial least squares structural equation modelling technique are employed to analyse the data. Findings indicate that nurses fear infection and experience stress-related presenteeism and burnout considerably. However, they perceive slightly inadequate level of organisational support. Fear of infection has resulted in stress-related presenteeism and burnout. Stress-related presenteeism has mediated the relationship between fear of infection and burnout. Perceived organisational support has negatively related to fear of infection and its negative consequences. In this research, to our knowledge, for the first time, the burnout, stress-related presenteeism, fear of infection and perceived organisational support levels of nurses are compared according to the pandemic-related criteria. Besides, the mediating role of nurses' stress-related presenteeism between their fear of contracting COVID-19 and burnout is discovered.

THE APPROACH OF ATATURK TO RELATIONS BETWEEN TURKEY AND ALBANIA BEFORE THE PROCLAMATION OF MONARCHY, IN THE LIGHT OF THE DIARIES OF RAUF FICO, THE MINISTER PLENIPOTENTIARY OF ANKARA
(2018) Ozca, Halil
The diaries of RaufFico, Albanian Minister Plenipotentiary to Ankara, gives a lot of useful information about Albania-Turkey relations that had not been stumbled across in the literature until today. The aim of this study is to point out Atatiirk's views on relations between Albania and Turkey, Albania and Italy, as well as his suggestions to Albanian envoy in Ankara about how to overcome the Albanian dependency on Italy. The research is based on the diaries of Fico, Albanian Minister Plenipotentiary to Ankara. The study is limited with focusing on the Italian factor in Albania's relations with Turkey rather than examining all aspects of the relationship between the two independent countries. Fico had had formal education in the Ottoman Empire and occupied bureaucratic posts such as being provincial governor and following independence of Albania started to work for Albanian government as an important diplomat. Therefore, his diaries provide us a plenty of information on the question of Albania's relations with Turkey as well as with Italy, particularly between 1925 and 1928 during which there had been a Republican regime in Albania. In fact, Fico's diaries give perfect information about close relations between Turkey and Albania and the importance given by Mustafa Kemal Atatiirk on these relations at bilateral level, at least until the destruction of the Republican regime by Ahmet Zogu who would proclaim himself as the King of Albania in 1928. The content of the Fico's diaries are very rich in a way that they consist problems of Orthodox Albanians in Istanbul, positions of Albanians in Kosovo, the exchange of Albanian Chams, reforms in Turkey, assassination attempt to Atatirk in izmir and main themes in Nutuk. It should be kept in mind that the scope of this study is confined, first, to suggestions of Ataturk to the Albanian government regarding getting rid of dependency on Italy, and second, to his foresight about Italy's position towards Albania and Turkey. In this respect, the Fico's diaries give invaluable information on all these subjects elaborated in this paper.

Introduction: Chronic obstructive pulmonary diseases are common causes of disease in the community and account for considerable percent of the caseload in primary health care facilities. For this reason, it is important to question and improve the knowledge of primary health care physicians. This study is designed to assess the level of knowledge for bronchial asthma and COPD of the primary healthcare physicians, both before and immediately after an educational course structured in the context of GARD Chronic Airway Diseases National Control Program. Materials and Methods: The participating physicians attended an intensive educational course on asthma and COPD. Twenty five item questionnaires for asthma and COPD were administered to the participants both before and immediately after the end of the course. Contribution of education to the level of knowledge was investigated by comparing the percentages of the correct answers in the pre-and post-test. Results: From 11 different cities, 1817 and 1788 primary health care physician were attended to the asthma and COPD educations, respectively. The accuracy rate of >= 75% was obtained from only 4 questions in pre-test asthma questionnaire. On the contrary, in 15 questions the accuracy rate was < 50%. The mean accuracy rate for the whole asthma test was 45.8%, and this rate raised to 69.6% after education course. The accuracy rate of >= 75% could not be obtained from any of the questions in pre-test COPD questionnaire. On the contrary, in 19 questions the accuracy rate was < 50%. The mean accuracy rate for the whole asthma test was 42.0%, and this rate raised to 71.3% after education course. Conclusion: It has been shown that, in primary care settings, the level of knowledge in asthma and COPD should be enhanced and that this increase can be achieved with an education course.
Association between Red Blood Cell Distribution Width and Acute Pancreatitis
(2014) Karabulut, Keziban Ucar; Narci, Huseyin; Ucar, Yildiz; Uyar, Mehmet; 25428195
Background: We aimed to determine whether there are any alterations in red blood cell width in patients diagnosed with acute pancreatitis. Material/Methods: This was a retrospective study of records of patients treated in emergency units and diagnosed with acute pancreatitis between January 2011 and April 2013. Records were investigated regarding patient age, sex, and causes of acute pancreatitis. Red blood cell width and amylase values obtained from the patients during diagnosis and after a full recovery from acute pancreatitis were added to the records. Results: Recorded red blood cell width and amylase values of 104 patients diagnosed with acute pancreatitis were statistically compared according to the time of sample collection. Samples were collected in the post-diagnostic period and after full recovery. Values of red blood cell width and amylase were found to be significantly higher in samples collected during hospital admission in comparison to those obtained from patients after fully recovering from acute pancreatitis (p<0.05). Conclusions: An increase in red blood cell width value is a marker of acute pancreatitis; therefore, we suggest that red blood cell width can be used as a tool for the early diagnosis and assessment of disease progression.

Blastoid Variant Mantle Cell Lymphoma with Complex Karyotype Including 11q Duplication
(2014) Ozer, Ozge; Toprak, Selami K.; Ote, Enver; Yilmaz, Zerrin; Sahin, Feride Iffet
We describe a case of blastoid mantle cell lymphoma with a complex karyotype. The blastoid variant is a rare type of non-Hodgkin lymphoma exhibiting an aggressive clinical course. Mantle cell lymphoma is a distinct entity of mature B-cell neoplasms genetically characterized by the presence of t(11;14). In the present case, conventional analysis revealed structural abnormalities of chromosomes 2, 4, 6, 10, 13, and 19, along with 3 additional marker chromosomes. The derivative 1 chromosome determined in the case was a result of t(1p;11q). Our interesting finding was the presence of a different translocation between 11q and chromosome 1 in addition to t(11;14). Thus, the resulting 11q duplication was believed to additionally increase the enhanced expression of cyclin D1 gene, which is responsible in the pathogenesis of the disease. Fluorescence in situ hybridization method by the t(11;14) probe revealed clonal numerical abnormalities of chromosomes 11 and 14 in some cells. The detection of multiple abnormalities explains the bad prognosis in the present case. On the basis of our findings, we can easily conclude that results of cytogenetic analyses of similar mantle cell lymphoma patients would provide clues about new responsible gene regions and disease prognosis. In conclusion, it has been suggested that the presence of multiple chromosomal aberrations in addition to the specific t(11;14) may have a negative impact on clinical course and survival rate.
Blood pressure prediction from speech recordings
(2020) Ankishan, Haydar
The aim of this study is to extract new features to show the relationship between speech recordings and blood pressure (BP). For this purpose, a database consisting of / a / vowels with different BP values under the same room and environment conditions is presented to the literature. Convolutional Neural Networks- Regression (CNN-R), Support Vector Machines- Regression (SVMs-R) and Multi Linear Regression (MLR) are used in this study to predict BP with extracted features. From the experiments, the highest accuracy rates of BP prediction from / a / vowel have been obtained based on Systolic BP values with CNNR. In the study, 89.43 % for MLR, 92.15 % for SVM-R and 93.65 % for CNN-R are obtained when ReliefF has been used. When the root mean square errors (RMSE) are considered, the lowest error value is obtained with CNN-R as RMSE = 0.2355. In conclusion, it can be observed that the proposed feature vector (FVx) shows a relationship between BP and the human voices, and in this direction, it can be used as an FVx in a system that will be developed in order to follow the tension of individuals.

Breast Involvement in Acute Lymphoblastic Leukemia
(2015) Pourbagher, Aysin
Extra-medullary infiltration of breast by acute lymphoblastic leukemia is very rare. Mammography, ultrasound and magnetic resonance imaging findings of leukemic breast involvement have been previously reported in the literature. However; ultrasound elastography findings of leukemic breast involvement have not been reported yet. Herein, we report ultrasound elastography and magnetic resonance imaging findings of a case with bilateral breast infiltration by T-cell acute lymphoblastic leukemia.
Broncholithiasis presenting with lithoptysis
(2018) Bozdas, Serife Savas; Ozyurek, Berna Akinci; 29970776
Broncholithiasis is defined as calcified or ossified material in the bronchial lumen. The most frequently seen symptoms are a non-productive cough and hemoptysis. Occasionally, broncholytic expectoration can be seen, which is known as lithoptysis. As this is not a common finding, a case diagnosed with lithoptysis is presented here.
