    Impact effect on different sized reinforced concrete specimens
    (National Institute of Science Communication and Information Resources (NISCAIR), 2015) Erdem R.T.; Gücüyen E.; Kantar E.; Bağcı M.
    Behavior of structural members under various loads has been a major interest. However, impact loading type is the least known one among them. Researchers have investigated the behavior of structural members under impact effect recently. For this reason, a well-instrumented experimental program is used to understand the impact behavior of six different sized reinforced concrete specimens. All specimens both have longitudinal and transverse reinforcements. A testing apparatus is developed to perform tests under impact loading. Accelerometers, optic photocells, dynamic force sensor, a data logger and connecting cables are used as well as testing apparatus. Free falling height and mass of steel hammer are taken constant in the study. Test program has been successful to provide several data to understand the impact behavior. Drop numbers and rebound movements of the hammer are determined according to damage situations. Acceleration values are measured from four different points of the specimens. The change of velocity and displacement values is determined for all specimens. Impact force is also measured for each free falling movement and absorbed energy values are calculated according to the area under the curve of impact force-displacement graphs. Test results give substantial information about impact resistances of reinforced concrete members. © 2015, Indian Journal of Engineering and Materials Sciences. All rights reserved.

    The effect of Reiki on depression in elderly people living in nursing home
    (National Institute of Science Communication and Information Resources (NISCAIR), 2016) Erdogan Z.; Cinar S.
    The aim of this study was to evaluate the effect of Reiki on depression in elderly persons living in nursing homes. The study was conducted randomized, controlled and experimental. The study universe consisted of 170 elderly and due to the long duration of the study and 90 elderly who volunteered for the study and fulfilled the inclusion criteria formed the sample. Ninety elderly individuals who were included in the study were separated into 3 groups using the random sampling method: 30 in the reiki group, 30 in the sham reiki group, and 30 in the control group. Data was collected using the Geriatric Depression Scale (GDS). There was a significant decrease in depression score of the Reiki group while there was no significant difference in depression scores of the sham Reiki and control group on the 4th, 8th and 12th weeks considering 1st week. In addition, the depression score of the Reiki group was lower than the depression scores of the sham Reiki and control group on the 4th, 8th and 12th weeks. The results of this study indicate that Reiki might be effective for reducing depression in elderly persons living in nursing homes. © 2015, National Institute of Science Communication and Information Resources (NISCAIR).
