    ACCREDITATION IN TURKISH UNIVERSITIES
    (Int Scientific Conference Sgem, 2008) Yalcin, Dilek; Senel, Secil; Akduman, Ibrahim
    As it is well-known, accreditation is a short of leadership and quality assurance in applied Science, computing, engineering, and technology education. In most countries in the world, the function of accreditation tor educational institutions is conducted by a government ministry of education. One of the most important Outcomes of economic globalization is the abolition of national boundaries in the fields of goods and services trade as well as production factors, namely capital and especially high-skilled labor. The need for free movement of persons in the globalize world increased discussions about world-wide recognition of diplomas and the ways of achieving it. The accreditation issue for the universities arose in such a global Milieu and attracted very much the interest of Turkish higher education institutions. Actually student exchange is made possible between European universities within the European Credit Transfer System (ECTS). The ongoing discussion about the impact of different accreditation systems in the EU oil the Student exchange is of great interest for Turkish Universities. In this paper, accreditation efforts to achieve international recognition for Turkish universities are discussed.

    In Vitro Dielectric Properties of Rat Skin Tissue for Microwave Skin Cancer Detection
    (IEEE, 2019) Aydinalp, Cemanur; Joof, Sulayman; Yilmaz, Tuba; Ozsobaci, Nural Pastaci; Alkan, Fatma Ates; Akduman, Ibrahim
    Dermal tissue characterization based on dielectric properties can be utilized as a non-invasive method for diagnosis of skin cancers. To enable such technology, there is a need to develop techniques that can rapidly and accurately collect the dielectric properties of the skin tissues. Therefore, the current measurement techniques and tools has to be optimized for skin cancer detection. To this end, this study presents dielectric property measurements with open-ended coaxial probes having small apertures customized for detection of skin cancer. Relative permittivity and conductivity of rat skin tissue is characterized with open-ended coaxial probes with outer diameters of 0.9mm and 0.5mm between 0.5GHz-6GHz and the measurement results are compared with the traditional probes having diameter of 2.2mm. The results agree well with the reported literature data.

    In-vivo Microwave Dielectric Properties of Healthy and Carcinogenic Rat Nasal Tissues from 500 MHz to 6 GHz
    (IEEE, 2019) Yilmaz, Tuba; Ozsobaci, Nural Pastaci; Alkan, Falma Ales; Kepil, Nuray; Akduman, Ibrahim
    Dielectric properties of rat nasal tissue and nasal carcinoma is given in this work between 500 MHz to 6 GHz. Nasal carcinoma is induced by oral administration of single dose 20 7,12-Dimethylbenz[a]anthracene (DMBA) dissolved in 1 ml olive oil to 47 days old Sprague Dawley (SD) rats. A granular tissue anomaly in one rat along with bleeding is observed after 15 weeks from the administration of the carcinogenic agent. In-vivo dielectric properties are collected both from the granular nasal carcinoma tissue and healthy counterpart with open-ended coaxial probe technique. A median dielectric property discrepancy is observed in the whole frequency range between the nasal carcinoma and healthy tissues.
