This research was planned to describe the traditional practices related to pregnancy, childbirth, puerperality, and child care among women in Karaman and the relation with sociodemographic characteristics. Women who gave birth at least once and who belonged to a low sociocultural level constituted this research basis, in which a screening model was used. An interview form was prepared according to literature information and was conducted face-to-face (N=195). Data were analyzed with arithmetic average, and significance of a contrast point between traditional practices according to sociocultural characteristics was analyzed with t-test. Of the women who contributed to this research, 76.4% of them stated that women who cannot have a baby are "massaged on the middle back" by traditional midwives in order to have a baby, 77.9% stated that an herb (Fatma Ana Eli) can be used to ease childbirth, 75.8% stated that a red-colored syrup (bogard) can be used to ease childbirth, 64.1% stated that the baby and mother should not be left alone for 40 days, 58.9% stated that the babies were "salted", and 66.1% stated that the baby's legs were swaddled for obtaining normal shape. In light of the research results, constant and regular educational courses for women related to inappropriate traditional practices are suggested.

The purpose of this study is to investigate whether or not conceptions of learning diverge in different science domains by identifying high school students’ conceptions of learning in physics, chemistry and biology. The Conceptions of Learning Science (COLS) questionnaire was adapted for physics (Conceptions of Learning Physics, COLP), chemistry (Conceptions of Learning Chemistry, COLC) and biology (Conceptions of Learning Biology, COLB) firstly and they were separately administered to 361 high school students at the same time. The factor structures of each questionnaire were also analyzed by exploratory factor analysis. The differences between students’ conceptions of learning in each questionnaire factors of all three domains were analyzed with paired-samples t-test. The results indicated differences in high school students’ conceptions of learning physics, chemistry and biology which were identified for all seven factors except application. In general sense, it was found that students preferred higher-level conceptions of learning biology more when compared with physics and chemistry domains. Possible implications about how students prefer to view learning from a higher-level perspective rather than a lower-level perspective, especially the ones with a high mean score in physics and chemistry (such as memorizing, preparing for exam and calculating and practicing) are discussed. © 2015 by iSER, International Society of Educational Research.

The present work reports the fabrication and detailed electrical properties of n-TiO2/p-ZnO heterojunction diode. We have determined the electrical characteristics of the device such as current-voltage (I-V) and capacitance-voltage (C-V) at room temperature. This structure showed a good rectifying behavior with a typical ideality factor of 3.62, which was considered high due to the current mechanism and large defect density at the interface. The possible conduction mechanism of the heterojunction diode was determined by analyzing the I-V characteristics. The obtained results show that the n-TiO 2/p-ZnO heterojunction diode is an excellent candidate for semiconductor device applications. © 2011 The Japan Society of Applied Physics.

In the present study, using sol-gel method titanium dioxide (TiO2) nanoparticles with a new doping material have been synthesized, and a Dodecyl Benzene Sulfonic Acid (DBSA)-doped TiO2/p-Si Metal-Oxide-Semiconductor (MOS) structure has been fabricated. The characterizations of the structural and morphological properties of the DBSA-doped TiO2 nanoparticles have been carried out by means of X-Ray Diffraction (XRD) and Atomic Force Microscopy (AFM), respectively. The XRD results show that DBSA-doped TiO2 have a crystalline rutile phase along the (110) growth direction. It was confirmed from AFM images that the nanostructure of DBSA-doped TiO2 is grown as rock-like. The electrical characteristics of the device have also been performed, including current-voltage (I-V) and capacitance-voltage (C-V) at room temperature. © 2013 Bentham Science Publishers.

This investigation addressed the structural, optical and morphological properties of tellurium incorporated zinc oxide (Te-ZnO) thin films. The obtained results indicated that Te-doped ZnO thin films exhibit an enhancement of band gap energy and crystallinity compared with non-doped films. The optical transmission spectra revealed a shift in the absorption edge toward lower wavelengths. X-ray diffraction measurement demonstrated that the film was crystallized in the hexagonal (wurtzite) phase and presented a preferential orientation along the c-axis. The XRD obtained patterns indicate that the crystallite size of the thin films, ranging from 23.9 to 49.1 nm, changed with the Te doping level. The scanning electron microscopy and atomic force microscopy results demonstrated that the grain size and surface roughness of the thin films increased as the Te concentration increased. Most significantly, we demonstrate that it is possible to control the structural, optical and morphological properties of ZnO thin films with the isoelectronic Te-incorporation level. © 2014 Elsevier B.V.
