Öğe Analysis of Relationships between Technological Pedagogical Content Knowledge and Educational Internet Use(Routledge, 2013) Sahin I.; Celik I.; Oguz Akturk A.; Aydin M.This study analyzes the relationships between preservice teachers’ technological pedagogical content knowledge (TPACK) and their self-efficacy beliefs in educational Internet use. Findings show statistically significant relationships among the knowledge domains in technology, pedagogy, content, and their intersections. Also, results from the canonical correlation analysis show that a statistically significant and strong relationship exists between the knowledge dimensions in the TPACK model and the self-efficacy beliefs in educational Internet use. Specifically, technology, content, and technological content knowledge domains are statistically significant predictors of preservice teachers’ self-efficacy beliefs in educational Internet use. ©, Copyright ISTE.Öğe Automation of electrical transmission lines' route optimization and project drawing [Enerji nakil hatlari güzergâh tespiti ve proje çiziminin otomasyonu](Gazi Universitesi Muhendislik-Mimarlik, 2015) Eroglu H.; Aydin M.There is a need for new Energy transmission lines (ETL) in order to meet the energy demand that has been increasing from past to present. Finding the optimum route and drawing the project is a time consuming and a complex problem for engineers. There are many studies for optimization of ETL's routing in the literature. However it is seen that there is a need for an interface that will facilitate the ETL routing by bringing together all the processes for ETL routing and preparing the project of the ETL by drawing the profile of the route. In this study, an interface using the Geographical information systems (GIS) is designed for finding the optimum route of ETL's, a project drawing program that can draw the profile and make all the other project processes is written. Also, controlling the project on the real terrain model by the users is ensured by the visualization of the ETL's projects on three-dimensional terrain model and satellite image.Öğe Effects of some humidity and IBA hormone dose applicatıons on rooting of M9 apple clonal rootstock softwood top cuttings(Academic Journals, 2010) Ersoy N.; Kalyoncu I.H.; Aydin M.; Yilmaz M.In this study, softwood cuttings were taken from M9 dwarf apple rootstocks in early June. Different indole-3-butyric acid (IBA) concentrations [0 (control), 500, 1500, 2500 and 3500 ppm], different air humidity levels (85 - 90%, 95-100%) and rooting media of perlite effects on rooting capability and root formation of M9 apple rootstock cuttings were examined. All the cuttings remained alive. The highest ratio of cutting callus formation was found in control group (58%) in 95 - 100% humidity level and 2500 ppm IBA hormone dose application in 85 - 90% humidity level. The highest rooting ratio was obtained from control group (46%) in 95 - 100% humidity level; the lowest one was 3500 ppm IBA dose application (17%) in 85 - 90% relative humidity level. The highest rooting surface lenght was found in 1500 ppm hormone dose (0.53 cm) in 95 - 100% and 2500 ppm IBA dose application (0.42 cm) in 85 - 90% humidity level. With respect to root numbers, the highest value was from 1500 ppm IBA application (1.29 number/cutting) in 95 -100% relative humidity, and 500 and 2500 ppm IBA doses (1.04 number/cutting) in 85 - 90% relative humidity level. The longest root was obtained from control group (2.03 cm) in 95 - 100% humidity level and 500 ppm IBA hormone dose (1.80 cm) in 85 - 90% humidity level. The shortest root was obtained from 1500 ppm IBA hormone application (0.79 cm) and control group (0.88 cm) in 95 - 100% humidity level. The highest root branching value was obtained from 1500 ppm hormone dose application (0.88 number/cutting) in 95 - 100% humidity level. © 2010 Academic Journals.
