Zekeriya Kaptan,Sadk Yndem
International Journal of Human Sciences , 2010,
Abstract: In this study, teaching processes of ba lama (a long-necked Turkish lute)and classical guitar are investigated to be comparativly. The study aims to answer the following questions: How has the teaching process of these instruments proceed in our country? What are the teaching strategies of this instrument? What differences and similarities between the teaching process of these two in instruments? This is a qualitative research. The opinions of experts by using the interview technique was taken. Also, related literature were examined comprehensivly. The data that obtained from research were evaluated by applying methods of descriptive analysis. The results indicate that teaching processes of ba lama and classical guitar have some differences in our country and each instruments has their own theaching styles
A Knowledge-poor Pronoun Resolution System for Turkish
Dilek Kü?ük,Meltem Turhan Yndem
Computer Science , 2015,
Abstract: A pronoun resolution system which requires limited syntactic knowledge to identify the antecedents of personal and reflexive pronouns in Turkish is presented. As in its counterparts for languages like English, Spanish and French, the core of the system is the constraints and preferences determined empirically. In the evaluation phase, it performed considerably better than the baseline algorithm used for comparison. The system is significant for its being the first fully specified knowledge-poor computational framework for pronoun resolution in Turkish where Turkish possesses different structural properties from the languages for which knowledge-poor systems had been developed.
Measuring Trust Component in Patient-Physician Relationship in Dermatology

Turkderm , 2009,
Abstract: Background and Design: Patient’s trust is an essential component of the patient-physician relationship. The aim of this study was to measure the level of trust of the patients in physicians, to determine factors affecting trust level and to propose some suggestions in order to improve trust component in patient-physician relationship. Material and Method: Three hundred five patients participated in the survey. A questionnaire was prepared to evaluate the level of patients’ trust in physician and satisfaction to the dermatology department and patients’ socio-demographic variables. Analyses of data obtained from questionnaires were performed using SPSS (Statistical Package of Social Science), version 15.0. Results: Patients have an average of 3.72±0.54 trust level (out of 5) in their physicians. This reveals the patients have a trust slightly above the medium level for their physicians. There are no statistically significant relationships between the trust level and other socio-demographic variables such as age, sex and income. Patients’ satisfaction level towards the dermatology department was 4.17±0.65. There was a positive and statistical significantly correlation between trust and satisfaction. Patients choose more cheerful and well-informed physicians. Trust had been determined as an important factor in the patient-physician relationship. Patients trust well-informed, sympathetic and honest physicians. Nevertheless, disrespectfulness and lack of information had been determined as the most distrusted physician behaviors.Conclusion: Although there are many studies to evaluate this subject in the literature as far as we determine this is the first study in dermatology practice in Turkey. Because there are many chronic diseases in dermatology to provide concordance of patients’ treatment and continuity to same physicians or medical clinics may be obtained by building the patient’s trust. In this sense, trust component in patient-physician relationship in dermatology must not be neglected. Also must be avoided for the distrusted attitudes and behaviors.
Problems and Proposals of Their Solutions in Dermatology Residency Training: A Survey of Residents’ Opinions in Turkey
Sadk Y?lmaz,Vahide Baysal Akkaya
Turkderm , 2009,
Abstract: Background and Design: There are many problems in dermatology residency training. The purpose of this study was to describe dermatology residents’ opinions about problems and proposals of their solutions of dermatology residency training programs in Turkey. In addition, by means of these estimations to propose efficient and standard curriculum components are aimed. Material and Method: A descriptive pilot study was designed and a questionnaire was prepared to describe the problems and suggestions for the solution in dermatology residency education. The survey was conducted between 20 June 2006 and 09 August 2006. The questions were prepared in accordance with a 1 to 5 Likert-type scale to evaluate the level of importance and sufficiency of the residents’ opinions. Results: Sixty seven (52 female, 15 male) residents responded to the survey. Based on the importance evaluation, although clinical-pathological meetings were the most important educational component, all other educational components were also indicated as important. Based on the sufficiency evaluation, the least sufficient educational components were photodermatology/laser therapy training (score, 1,82 of 5,0 ) and cosmetic dermatology (1,83). Sufficiency levels of educational components such as textbook review, translation and discussion (3,86) journal club (4,04), preparation of seminar (4,03) and allergy training (2,95) were evaluated as sufficient. All other educational components were determined as insufficient. Overall, the greatest discrepancies between the importance and sufficiency for all educational components were observed in cosmetic dermatology education (2,50).Conclusion: This is the first study to assess dermatology residency education based on the residents’ perspectives, in Turkey. These results show the necessity for review and revise of some of the elements and the necessity to prepare a standard curriculum of dermatology residency education. It is appropriate to concentrate on this item in the new program which will be prepared.

Turkish Journal of Oncology , 2006,
Abstract: OBJECTIVES: The surface doses of high energy photon beams show variability depending on the design of the treatment machine. Especially while using bolus that has a direct effect on surface and build-up region doses, defining correctly in the treatment planning system used for patient treatment is very important. It needs to be measured for each radiation beam used. In this study, the dose change of high energy beams surface and build-up region that were used in I.U. Oncology Institute according to the field size and the skin source distance were investigated. METHODS: Co-60 teletherapy equipment, Orion 4 (MV), Saturn 42 (6-15 MV) high energy x-rays were used. Measurements were made for different field sizes and source skin distances by using Marcus–type parallel plate ion chamber at water equivalent solid phantom, at surface and build-up region. Measured surface and build-up doses were installed to CMS XiO treatment planning system. RESULTS: As a result of this study, the surface dose increased linearly as the field size increased and the maximum dose point was moved toward the surface by 1-2 mm as predicted. Surface doses for a 10x10 cm field size are 24.3%, 17.4%, 12.6% and 10.2% respectively for Co-60, 4MV, 6MV and 15MV. With the increase in skin source distance, a decrease in surface doses is observed. CONCLUSION: The use of correct information is achieved by downloading surface doses measured for different field sizes to the treatment planning system.

Journal of Clinical and Experimental Investigations , 2011,
Abstract: Objectives: Platelet contributed tissue damage and inflammations have been of increased interest. It was previously suggested that platelets have an important role in patients with acute pancreatitis (AP). We aimed to assess the mean platelet volume (MPV) which is described as an indicator of platelet activation and platelet count in patients with AP.Materials and methods: The study group consisted of 30 patients with AP and 30 control subjects who were matched for age, gender, body mass index (BMI). MPV values and platelet counts were measured on admission.Results: Mean platelet volume was significantly higher among patients with AP when compared with control group (8.82±1.33 vs. 7.94±0.54 fL respectively; p < 0.01). Platelet count was significantly lower among AP patients when compared with control group (223.0±46.2 vs. 295.3±58.9 ×109/L respectively; p < 0.001). The level of CRP was significantly higher in patients with AP compared with control group. Platelet and MPV were correlated with serum CRP levels in correlation analysis (p<0.01; r = -0.364, r = 0.406 respectively). We have shown increased MPV, an indicator of platelet activation, in patients with AP. The platelet count was found to be decreased in patients with AP. MPV values and platelet counts were correlated with serum C-reactive protein level that is known as an inflammation marker.Conclusion: In conclusion, increased MPV level in AP may be a marker for the diagnosis of acute pancreatitis.

Indefinite Almost Paracontact Metric Manifolds
Mukut Mani Tripathi,Erol K?l??,Selcen Yüksel Perkta?,Sadk Kele?
International Journal of Mathematics and Mathematical Sciences , 2010, DOI: 10.1155/2010/846195
Abstract: We introduce the concept of ( )-almost paracontact manifolds, and in particular, of ( )-para-Sasakian manifolds. Several examples are presented. Some typical identities for curvature tensor and Ricci tensor of ( )-para Sasakian manifolds are obtained. We prove that if a semi-Riemannian manifold is one of flat, proper recurrent or proper Ricci-recurrent, then it cannot admit an ( )-para Sasakian structure. We show that, for an ( )-para Sasakian manifold, the conditions of being symmetric, semi-symmetric, or of constant sectional curvature are all identical. It is shown that a symmetric spacelike (resp., timelike) ( )-para Sasakian manifold is locally isometric to a pseudohyperbolic space (resp., pseudosphere ). At last, it is proved that for an ( )-para Sasakian manifold the conditions of being Ricci-semi-symmetric, Ricci-symmetric, and Einstein are all identical. 1. Introduction In 1976, an almost paracontact structure satisfying and on a differentiable manifold was introduced by Satō [1]. The structure is an analogue of the almost contact structure [2, 3] and is closely related to almost product structure (in contrast to almost contact structure, which is related to almost complex structure). An almost contact manifold is always odd dimensional but an almost paracontact manifold could be even dimensional as well. In 1969, Takahashi [4] introduced almost contact manifolds equipped with associated pseudo-Riemannian metrics. In particular, he studied Sasakian manifolds equipped with an associated pseudo-Riemannian metric. These indefinite almost contact metric manifolds and indefinite Sasakian manifolds are also known as -almost contact metric manifolds and -Sasakian manifolds, respectively [5–7]. Also, in 1989, Matsumoto [8] replaced the structure vector field by in an almost paracontact manifold and associated a Lorentzian metric with the resulting structure and called it a Lorentzian almost paracontact manifold. An -Sasakian manifold is always odd dimensional. Recently, we have observed that there does not exist a lightlike surface in a -dimensional -Sasakian manifold. On the other hand, in a Lorentzian almost paracontact manifold given by Matsumoto, the semi-Riemannian metric has only index and the structure vector field is always timelike. These circumstances motivate us to associate a semi-Riemannian metric, not necessarily Lorentzian, with an almost paracontact structure, and we shall call this indefinite almost paracontact metric structure an -almost paracontact structure, where the structure vector field will be spacelike or timelike according as

Mathematics , 2009,
Abstract: In this paper we study the 3-dimensional $(\varepsilon) $-para Sasakian manifolds. We obtain an necessary and sufficient condition for an $(\varepsilon ) $-para Sasakian 3 -manifold to be an indefinite space form. We show that a Ricci-semi-symmetric $(\varepsilon) $-para Sasakian 3 -manifold is an indefinite space form. We investigate the necessary and sufficient condition for an $(\varepsilon) $-para Sasakian 3 -manifold to be locally $\varphi $-symmetric. It is proved that in an $ (\varepsilon) $-para Sasakian 3-manifold with $\eta $ -parallel Ricci tensor the scalar curvature is constant. It is also shown that every $(\varepsilon) $-para Sasakian 3-manifolds is pseudosymmetric in the sense of R. Deszcz.
