    The development and validation of a Turkish insulin treatment self-management scale child form (ages 8-18) and parent form
    (Galenos Yayincilik,, 2019) Özçelik Ç.Ç.; Aktaş E.; Celasin N.Ş.; Okuroğlu G.K.; Şahin Ş.
    Objective: The aim of the study was to develop an Insulin Treatment Self-management Scale; both Child Form and Parent Form for children ages 8-18 with type 1 diabetes. Methods: Children with type 1 diabetes and their parents participated in the study. Development of a methodologically designed scale was conducted to investigate insulin treatment self-management of children with type 1 diabetes. Results: A total of 331 children and their parents were recruited. Children and parents completed the data collection tools by themselves. The final scale had two subscales; one was related to cognitive and behavioural expressions regarding insulin treatment (self-efficacy) and the other to emotional aspects of self-maagement of insulin treatment (emotional impacts). The scale was shown to be valid and reliable. Conclusion: This study was a valid and reliable scale for measuring insulin treatment self-management in children with type 1 diabetes. Thus can be used to assess insulin treatment self-management in children with type 1 diabetes and their parents as well as a tool for effective nursing care. © 2019 by Turkish Pediatric Endocrinology and Diabetes Society.

    Investigation of in-plane and out-of-plane wall behavior related to lateral loading depending on wall profiles and opening arrangements in Hellenistic Towers; [Helenistik kulelerde yanal yüke ilişkin düzlem içi ve düzlem dışı duvar davranışının duvar profilleri ve açıklık düzenlerine bağlı olarak incelenmesi]
    (Gazi Universitesi Muhendislik-Mimarlik, 2020) Gençer F.; Hamamcıoğlu-Turan M.; Aktaş E.
    Dry masonry wall profiles constructed without using bonding material between blocks are encountered in different building types dated to Greek, Hellenistic and Roman periods. Depending on development of earthquake experiences, dry masonry wall profiles vary in terms of wall thickness, number of layers, relationship of layers and size, form, organization and relationship of blocks. In this study, the construction details increasing the structural strength in watch towers constructed in Hellenistic Period are aimed to be determined. This study is limited with investigation of effect of wall profiles and opening organizations on in-plane and out-of-plane wall behaviors under lateral loading. Primarily, wall profiles and opening types of dry masonry towers in ancient Caria, Pamphylia and Cilicia regions, that have not lost authenticity and integrity or had information about their authentic form, were documented. By using gathered data, hypothetic towers with different wall profiles and opening types are designed. To determine in-plane and out-of-plane wall behavior of hypothetic towers, simulation of quasi-static tilt analysis based on equilibrium were carried out, and form changes at walls and collapse angles of towers were identified. Wall profile and opening properties effecting on structural strength under lateral loading were determinedd. © 2020 Gazi Universitesi Muhendislik-Mimarlik. All rights reserved.

    Structural vulnerability of ancient dry masonry towers under lateral loading
    (Elsevier Ltd, 2020) Gençer F.; Hamamcıoğlu-Turan M.; Aktaş E.
    Understanding how the original characteristics contribute to the structural behaviour of antique structures should be the initial stage of planning for conservation work. This study aims to identify the structural behaviour of dry masonry towers under lateral loadings, so that the decision-making process when determining their restoration can be adequately supported. Dry masonry towers in ancient Caria, Pamphylia, and Cilicia Regions are examined. Each of these three areas have very different seismic characteristics. A hypothetical testing process was designed by combining different characteristics from each of the towers. As a result, the characteristics affecting the structural resistance were determined as; the staggering ratio, the stone depth, the ratio between block length and height, the proportional relationship between height and length, the area, number and position of openings, and the distribution of header stones. These characteristics all interact together to determine the failure mechanism; so, understanding this interaction is critical when considering conservation. © 2020 Elsevier Ltd
