    Evaluation of Radioactivity Levels and Radiological Hazards of Some Endemic Plants Used as Medicine in Ankara, Turkey
    (2023) Guven, Aysel; Cengiz, Gulcin Bilgici; Caglar, Ilyas; Ates, Simge; 37536028
    In this study, natural radioactivity levels (Ra-226, Th-232, and (4) K) of some medicinal plant samples with known anti-oxidative properties, which are frequently consumed by animals and humans, were obtained from Ankara province and its surroundings (Mamak, Kizilcahamam, Beypazari, Kahramankazan, and Polatli districts) were determined using a thallium-doped sodium iodide NaI(Tl) gamma spectrometry. By using the determined natural radioactivity concentrations in the collected plant samples, the number of radiological doses that people could be exposed by consuming these plants was calculated. As a result of the study, Ra-226, Th-232, and (4) K radioactivity concentration ranges of the plant samples were found be 14.69 +/- 1.27-59.08 +/- 3.12 Bq kg(-1), 1.78 +/- 0.04-50.05 +/- 2.76 Bq kg(-1) and 207.24 +/- 34.09-826.13 +/- 25.40 Bq kg(-1), respectively. The highest Ra-226, Th-232, and (4) K activity concentrations were measured in Astragalus densifolius subsp. ayashensis (Kahramankazan), Astragalus kochakii (Kahramankazan) and Rumex patientia (Patience Dock) (Kahramankazan) plants, respectively. The lowest Ra-226, Th-232 and,(4) K activity concentration plants were determined respectively as Rumex patientia (Mamak), Lavandula angustifolia (Kizilcahamam), and Astragalus acikirensis (Polatli). The establishment and routine repetition of environmental radioactivity monitoring programs in each region are important for human and animal health, and the results of this study gain importance for Ankara and its surroundings in terms of environmental health.

    Örgütsel Bağlılığın Örgütsel Vatandaşlık Davranışına Etkisi Örgütsel Adaletin Aracılık Rolü: Makina İmalat İşletmelerine Yönelik Bir Araştırma
    (Bildiri Kitabı ,1 ,1 ,422-425, 2012) Güçel, Cem; Turgut, Hakan; Tokmak, İsmail; Öktem, Şükran
    Bu çalışmada çalışanların, örgütsel bağlılığının (ÖB) örgütsel vatandaşlık davranışına (ÖVD) etkisi ve bu etkide algılanan örgütsel adaletin (ÖA) aracılık rolünün araştırılması amaçlanmıştır. Ankara OSTİM Sanayi Sitesinde faaliyet gösteren işletmeler üzerinde yapılan araştırma sonuçlarına göre örgütsel bağlılık ile örgütsel adaletin örgütsel vatandaşlık davranışını doğrudan ve pozitif yönde etkilediği gibi örgütsel adaletin kısmi aracılık etkisinin de bulunduğu belirlenmiştir. This study aims to reveal not only the impact of organizational commitment (OC) and organizational justice (OJ) on organizational citizenship behaviour (OCB) but also the influence of OJ on the association between OB and OCB. The findings based on analyses, which are conducted to the data collected from the firms located in OSTİM Organized Industrial Area in Ankara, demonstrate that OC and OJ have positive impact on OCB while OJ has a mediating effect on the association between OC and OCB.
