Zonguldak il merkezi ilköğretim 5. Sınıf öğrencilerinin el hijyenine yönelik davranışlarının belirlenmesi

Kalıncı, Nihal

İlköğretim döneminde çocuklar daha kolay öğrenmekte ve sağlık ile ilgili davranışlar geliştirebilmekte ve geliştirdikleri davranışları ileriki yaşamlarına yansıtmaktadır. Günlük yaşamda birçok işi yaparken kullanılan eller sık kirlenmekte ve bulaşıcı hastalık etkeni haline gelmektedir. Çocuklardan başlayarak topluma kolay ve ekonomik olan el hijyeni davranışlarının kazandırılması ile bulaşıcı hastalıkların yayılımı ve görülme sıklığı azaltılacak ve toplumun sağlık düzeyini yükseltecektir. Araştırma, Zonguldak İli Merkez Mahallelerinde bulunan ilköğretim 5. sınıf öğrencilerinin el hijyenine yön ...Daha fazlası

Cryptococcosis caused by Cryptococcus neoformans has a wide range of clinical presentations, varying from asymptomatic colonization of the respiratory airways to the dissemination of infection into different parts of body. It is more common among immunosupressed patients such as human immunodeficiency virus (HIV) positive ones. In this report we present a case with C. neoformans meningitis and miliary pulmonary infiltrates suggesting pulmonary tuberculosis without HIV infection. A-70-years-old male was admitted to the hospital with mental confusion, 3-weeks history of headache, weight loss, dr ...Daha fazlası

Investigation of the Association Between Chronic Hepatitis B and C Infections and TNF-alpha(-308) Gene Polymorphism

Borekci, Gulay | Aras, Nurcan | Kandemir, Ozlem | Yalin, Serap | Celik, Sevim Karakas | Berkoz, Mehmet

Cytokines and genetic factors play important roles in the pathogenesis of chronic hepatitis B (CHB) and chronic hepatitis C (CHC) infections. Variations in cytokine genes may effect the gene expression and may lead to changes in the clinical manifestations of diseases. One of the single nucleotide polymorphisms in the promoter region of tumor necrosis factor-alpha (TNF-alpha) gene is the polymorphism at -308. position which was investigated in many studies by means of its relationship between CHB and CHC infections, however their results are incompatible. Furthermore, there is no sufficient da ...Daha fazlası

Adaptive echo and noise cancellation for car hands-free voice communication

Onur, Tuğba Özge | Hacıoğlu, Rıfat

The speech signals are formed with echo caused by the reflections and also noise caused by engine, tyres, wind, etc during using hands-free voice communication in automobiles. In this paper, it has been focused on the adaptive filtering algorithms that based on eliminating purpose of not only noise removal but also separation in speech signals with echo and noise. It has been evaluated that the speech signals separation performance by comparing adaptive filtering methods that made with Least Mean Squares (LMS) and Recursive Least Squares (RLS) algorithms. Signals belong to near and far end spe ...Daha fazlası

The controller of the camera used in target tracking for unmanned vehicle with model predictive controller

Altan, Aytaç | Hacıoğlu, Rıfat

In this study, unmanned vehicles used for target tracking camera RRP (revolute revolute prismatic) joint structure with a three-jointed robot arm with the position, velocity and acceleration control is made. In order to be able to follow the specified trajectory, the system used in the control of the robot arm with joint structure RRP target tracking model based on changing according to the structure proposed by the MPC is implemented. Also the PID (Proportional Integral Dervative) is provided with control comparison was made. MATLAB/Simulink simulations performed unmanned vehicles used for ta ...Daha fazlası

Visual line tracking with vector field guidance for UAV

Köksal, Kerem | Surucu, Dilek | Surucu, Murat | Hacıoğlu, Rıfat

In this study, it is aimed to follow a visual route by an Unmanned Aerial Vehicle (UAV). The recognition of the predetermined line by using image processing algorithms and the process of following the route by using the method of Tangent Vector Field Guidance (TVFG) have been performed in indoor and outdoor experiments. UAV's following the correct route has been ensured by calculating the deflection caused by some factors such as wind and light which adversely affect the flight of UAV. In Vector Field Guidance method, the direction angles calculated by using the vector fields that will follow ...Daha fazlası

The effect of the ring transducer system in ultrasonic imaging

Onur, Tuğba Özge | Hacıoğlu, Rıfat

The spatially limited plane (SLP) wave can be created by exciting the ring transducer elements with different amplitudes and at different times. Although the ring transducer initially worked well, many transducer elements have become inoperative, due probably to service life and material life. The result of these bad elements is artifacts in the resulting spatially limited plane waves. In this study, the effects of bad elements of ring transducer system (RTS) which is used to obtain high quality images by using inverse scattering techniques in formation of the SLP wave are investigated. Also, ...Daha fazlası

Image enhancement in ultrasound imaging

Onur, Tuğba Özge | Hacıoğlu, Rıfat

In this paper, two different methods are suggested in order to provide image enhancement in ultrasonic B-mode imaging. By obtaining RF data from two different phantom used to form B-mode image, their spectral characteristics were observed. Then by forming RF envelope from obtained data, conversion of envelope to color image is provided. Logarithmic compression and histogram equalization methods found in literature are used to improve image quality. From the results obtained, it is observed that both algorithms are effective based on the intended use when they are applied individually. © 2016 I ...Daha fazlası
