    Comparison of Geological Structures and Satellite-based Tectonic Lineaments in Gülağaç (Aksaray) and its Surroundings
    (Hitit Üniversitesi, 2024) Demircioğlu, Ramazan
    The study area covers the Gülagaç district of Aksaray and its surroundings in the Central Anatolia region of Turkey. The basement of the study area consists of metamorphic rocks belonging to the Paleozoic–Mesozoic-aged Kaman Group. Mesozoic-aged ophiolites overlie these rocks, and both are cut by Late Cretaceous-aged igneous rocks. These units were then overlain by Palaeocene-Quaternary-aged volcanic and sedimentary units. The region has important geological structures that have undergone polyphase deformation, especially in the Eocene units. As a result of these deformations, faults, fractures, folds and linearities were formed. . These structures were compared with satellite-based tectonic lineaments, and it was observed that the general orientations of the lines determined in the field and the satellite-based lineaments were largely compatible. The results of this study can make an important contribution to the exploration of mineral and geothermal resources in the region.

    The extraction and structural analysis of lineaments around Gülsehir (Nevşehir) using GIS methods
    (Universidad Nacional Autonoma de Mexico, 2024) Demircioğlu, Ramazan; Eren, Yaşar; Coşkuner, Berkant
    This study aims to determine the lineaments in the Palaeozoic - Cenozoic rocks outcropping around Gülşehir (Nevşehir) using Landsat-8 satellite images, shaded relief and slope maps and to compare them with field studies. Faulted structures in the region are formed by E-W trending thrusts, NE-SW trending reverse faults and NW-SE trending normal faults. A Digital Elevation Model (DEM) was used to produce the lineament maps. Google Earth and Landsat 8 images were also used. The shaded relief map (SRM) and slope map were derived from the DEM. The analysis of the produced linearity maps showed that the slope map and the integrated (SRM) map were more consistent with the field data. The lineament maps derived from the slope maps are largely consistent with the faults and fractures identified in the field. According to the strike maps, N15-300E and N75-900W orientated structures dominate the region. Lineaments show a tendency in all directions due to polyphase deformation.

    Association of the relationship between tectonic lineaments and natural springs around Nigde Massif, central Anatolia, Turkey
    (Springer, 2024) Demircioğlu, Ramazan
    In this study, the aim was to determine the relationship between tectonic lineaments derived from satellite data and springs. The study area covers Gümüşler (Nigde) and its surroundings in the northern Nigde Massif. The study investigated the connection between this area’s tectonic lineaments and natural water resources. Remote sensing methods used in mineral exploration and the determination of geothermal fields have also been applied in this study, supported by intensive field studies. The high-grade metamorphic rocks of the massif exhibit faulted and fractured structures due to polyphase deformation, giving these rocks important aquifer characteristics. Numerous springs have formed due to the effects of faults and fractures. The study definitively established the relationship between 82 natural water resources (springs) and tectonic lineaments. Almost 87% of the identified natural water resources are located on lineaments. In addition, other springs were determined to have discharge due to discontinuities in formation boundaries.

    Polyphase deformation features and extensional detachment faults on the northern and southern edges of the Nigde Massif (Central Anatolia-Turkey)
    (Guangzhou Institute of Geochemistry, 2024) Demircioğlu, Ramazan
    The polyphase deformation features and detachment faults on the northern (Gumusler) and southern (Camardı) borders of the Nigde Massif rocks, as well as the structures developed as a result of these faults, are investigated in this paper. The Nigde Massif in the studied areas is basement Palaeozoic–Mesozoic metamorphic units. The Late Cretaceous Uckapılı granodiorite and Sineksizyayla meta-gabbro introduced the Nigde massif. These units are overlain unconformably by Late Cretaceous-Quaternary rocks. The metamorphic rocks on the massif's southern edge underwent 5-phase ductile deformation, whereas the metamorphic rocks on the northern margin underwent 3-phase folding. Both the northern and southern edges include post-Middle Eocene extensional detachment features. These are most likely extensional detachment faults related to the massif's uplift. Central Anatolia is still under an extensional tectonic regime today. Therefore, detachment fault activity and occurrence continue. A large portion of the low-angle normal faults shows an extensional detachment feature. The detachment faults identified north and south of the study area are also active today.

    Relationship Between Tectonic Lineaments and Springs North of Avanos (Central Anatolia, Turkey)
    (John Wiley and Sons Inc, 2024) Demircioğlu, Ramazan
    The study area covers Avanos-Ozkonak and its surroundings north of Nevsehir province. An attempt was made to determine the relationship between tectonic lineaments and springs in the area. It was found that there is a close relationship between the location of springs and tectonic lineaments. In recent years, lineaments have been used in mineral exploration studies and geothermal areas. Remote sensing methods have also been used in this study. The relationship between tectonic lineaments (faults and fractures) and spring formations obtained from field studies and satellite-based studies was evaluated. Metamorphic rocks belonging to the Kirsehir massif and Paleocene–Middle Eocene aged units were subjected to polyphase deformation. As a result of these deformations, faults and cracks were formed. This situation has given aquifer properties to the rocks. At the same time, many springs were formed by faults and cracks. This study determined the relationship between 342 springs identified during field works and tectonic lineaments. Approximately 89% of the springs identified in the field were found to be located on the tectonic lineaments obtained from the satellite imagery. Some springs discharged from discontinuities on the formation boundaries.

    Investigation of Salanda Fault Zone, between Yesiloz and Gumuskent (Nevsehir-Turkey) with PSInSAR
    (Universidad Nacional Autonoma de Mexico, 2024) Demircioğlu, Ramazan; Oktar, Osman
    In this study, the section of the Salanda fault zone between Yesiloz village and Gumuskent (Nevsehir, Turkey) was investigated by geodetic methods, and the amount of movement in this area was determined. We used a Persistent Scatterer Interferometric Synthetic Aperture Radar (PSInSAR) to determine the line of sight (LOS) movement. Previous studies using geological and geomorphological indices have shown that the Salanda fault zone is active. For the first time in this study, 36 synthetic aperture radar (SAR) images acquired between January 8, 2020, and November 29, 2022, were used in PSInSAR analysis. When the annual velocity values of the stud area in the LOS direction were analysed, annual subsidence values of up to 7.6 mm and annual uplift values of up to 7.2 mm were revealed. These movements indicate that the Salanda fault is active and normal fault characteristics. However, it also has a dextral strike-slip component.

    The effect of mindfulness-based interventions on caregiver burden, quality of life and psychological distress in caregivers of adults with chronic diseases: Systematic review and meta-analysis of randomized controlled trials
    (John Wiley and Sons Inc, 2024) Erdoğan Yüce, Gülyeter; Döner, Ayser; Bilgin, Aylin; Muz, Gamze
    Chronic diseases requiring long-term treatment, care, and follow-up can negatively affect the health and well-being of caregivers. Mindfulness-based interventions (MBIs) are increasingly used as a mental health intervention to control the psychological problems experienced by caregivers and improve their quality of life. Aims: This systematic review and meta-analysis aimed to provide evidence for a holistic evaluation and synthesis of the effects of MBIs applied to caregivers of adults with chronic disease on the burden, quality of life, and psychological distress. Methods: Studies evaluating the effects of mindfulness-based interventions on caregivers of adults with chronic diseases and published through September 2023 were searched using PubMed, Web of Science, Scopus, and EBSCO. Methodological quality was assessed with the modified JADAD scale, and bias was assessed with the Cochrane risk-of-bias tool for randomized trials. Randomized controlled studies were included. The standardized mean difference with a 95% confidence interval was calculated. Heterogeneity was analyzed using the I2 test and Q statistic. Publication bias was assessed with the Egger regression test. Results: This meta-analysis included 12 studies. Pooled evidence found that MBIs resulted in significant improvements in stress, anxiety, depression, and caregiver burden in caregivers of adults with chronic illness but had no significant effects on quality of life, resilience, and mindfulness. The Egger's test showed no evidence of publication bias. Linking Evidence to Action: MBIs can be considered as a helpful method to increase psychological well-being and reduce caregiver burden in caregivers of adults with chronic diseases. These findings may direct clinicians to conduct mindfulness-based interventions for caregivers of adults with chronic diseases.

    (Lippincott Williams & Wilkins, 2023) Muz, Gamze; Bilgin, Aylin; Döner, Ayser; Erdoğan Yüce, Gülyeter
    Background Touch therapy is used in the control of physical and psychological symptoms in cancer patients. However, its effectiveness has not been well studied. Objectives The aim of this study was to examine the effectiveness of touch therapy intervention on symptoms and psychosocial factors for patients with cancer. Method Four electronic databases were used to identify all experimental studies that examine the effects of touch therapy on symptoms and psychosocial factors for patients with cancer. The standardized mean differences between groups in levels of symptoms and psychosocial factors for postintervention were computed for each study. Result The pooled results suggest that touch therapy intervention effectively reduces pain, fatigue, anxiety, and negative mood among patients with cancer postintervention. However, touch therapy intervention did not affect the quality of life and stress. Conclusion A significant effect of touch therapy was the reduction of physical and psychological symptoms in cancer patients. Implications for Practice Touch therapy could be safely integrated into the clinical practice of patients with cancer.

    A review of the Anatolian Gomphocerus Thunberg, 1815 (Orthoptera: Acrididae: Gomphocerinae) via morphological and bioacoustics characters: data suggesting a new species, a new subgenus and three new statuses
    (Zootaxa, 2023) Mol, Abbas; Şirin, Deniz; Taylan, Mehmet Sait; Sevgili, Hasan
    Gomphocerus Thunberg, 1815 (Orthoptera, Acrididae, Gomphocerinae) is an interesting genus with clavate antennae, differing from the other genera by the pyriform (pear-shaped) anterior tibiae in the male and being represented by 17 taxa species-subspecies in the Palaearctic region. Anatolian species of this genus have not been adequately studied, and almost all of them are cold tolerance species and live in high mountain meadows. The previous studies indicate that the taxa belonging to Gomphocerus have some taxonomic problems in both Turkey and the Palaearctic region. For this reason, the genus needs taxonomic revision due to its biogeographical, biodiversity, taxonomical and faunistic issues for which morphological and bioacoustics characteristics are to be used. This study was carried out between the years 2015 and 2021 at different altitudes and habitats of the mountains, where Gomphocerus specimens were collected from various localities in Anatolia. Since the species belonging to the genus have distinct morphological differences, the genus is divided into two subgenera: the nominate subgenus and a new subgenus Bolivarianus Mol, subgen. n. In addition, a new species of the nominate subgenus Gomphocerus (Gomphocerus) eyluldenizi Mol, sp.n. is described from Erzurum province (Eastern Anatolia) and when both morphology and bioacoustics characteristics are evaluated, three subspecies of the genus distributed in Anatolia are designated at species level: Gomphocerus (Gomphocerus) turcicus Mistshenko, 1951 stat. n. et sp. rev., Gomphocerus (Bolivarianus) acutus Karabag, 1957 stat. n., and Gomphocerus (Bolivarianus) hemipterus Karabag, 1953 stat. n. Furthermore, a key to the subgenus and species level for Anatolian members of Gomphocerus is provided with original figures, a distributional map and suggestions for conservation status according to IUCN categories are presented.

    Disseminating extra-role service behavior in the public sector: the effect of health-oriented leadership and work engagement
    (Centre of Sociological Research, 2023) Kerse, Gökhan; Özdemir, Şefik; Soyalın, Mesut
    This study focused on health-oriented leadership (HoL), attempting to determine whether this new type of leadership affects extra-role service behavior either directly or indirectly (through work engagement). Data were collected from public employees working in the service sector in a province in Turkey through the convenience sampling method. The study hypotheses were tested with structural equation modeling (SEM) using the SmartPLS software. The analysis findings have revealed that the perception of health-oriented leadership positively affects extra-role service behavior. Moreover, this effect was present not only directly, but also indirectly (through work engagement). The findings have also confirmed that health-oriented leadership is important in increasing public employees' engagement and extra-role service behaviors. Therefore, it was determined that health-oriented leadership brings positive outcomes in the public sector.

    (IWA Publishing, 2023) Demircioğlu, Ramazan; Dursun, Yusuf Gökhan; Demircioğlu, İlknur
    In this study, an area of 150 km2 with important settlements and agricultural areas within the Kızılırmak and Kuyulukışla grabens, in the north of Nevşehir province (Turkey), was investigated. This study aimed to evaluate the hydrochemical properties and water quality of the vital groundwater in the study area, determine effective utilisation methods, and make recommendations for sustainable use. From the data obtained as a result of these analyses, sodium adsorption ratio (SAR) and sodium percentage (%Na) values were calculated and compared with WHO (World Health Organization) and TS-266 (Turkish Standards) quality standards to determine the characteristics of water for human consumption and irrigation for agricultural purposes. Based on these values, Wilcox diagrams and US Salinity Laboratory diagrams were used. According to these evaluations, it was found that sample SMP1 is not suitable for use as drinking water according to the basic parameters in the reference standards, while the other samples are suitable for drinking and human consumption. Electrical conductivity, %Na, SAR values, US Salinity Laboratory, and Wilcox diagrams were used to evaluate the use of water resources for irrigation purposes. According to the results obtained, all samples except sample SMP1 were found to be suitable for use as irrigation water.

    Düzce Depremi Sonrası Gazete Manşetlerinin Bütünleşik Afet Yönetimi Sürecine Göre Değerlendirilmesi
    (Ankara Üniversitesi, 2023) Akıl, Kübra; İnal Önal, Ebru
    Doğa kaynaklı afetler toplumların fiziksel, psikolojik, sosyo-ekonomik durumları üzerinde ciddi etkiler meydana getirmektedir. Ülkemiz de jeolojik konumu itibariyle depremler başta olmak üzere pek çok afete maruz kalmaktadır. Depremlerin yıkıcı etkilerinin azaltılması etkili ve bütünleşik bir afet yönetimi ile mümkün olabilmektedir. 1999 Marmara depremi sonrasında, risk azaltma evresinde yapılması gereken, planlama, zarar azaltma ve hazırlık konularında eksiklikler tespit edilmiştir. Kriz yönetimi anlayışıyla yönetilmeye çalışılan depremde pek çok koordinasyon ve iletişim sorunları yaşanmıştır. Bütünleşik afet yönetimi sistemi ile afet öncesi zarar azaltma ve hazırlık çalışmalarına ağırlık vermek elzemdir. Afetler öncesi halkın bilgilendirilmesi ve afetlere hazırlık konusunda bilinçlendirilmesi meydana gelen acil durumların afete dönüşmesini önlemeye yardımcı olacaktır. Medyanın da bilgilendirme ve bilinçlendirme konusunda önemi yadsınamaz. Medya yalnızca afetlerden sonra bilgilendirme olarak değil, afet öncesi bireylerin yapması gerekenleri de kapsayan bilinçlendirme çalışmalarına yer vermelidir. Bu çalışmanın amacı da 23 yıl sonra meydana gelen Düzce depreminin gazete manşetlerinde afet yönetimi süreçlerine göre nasıl ele alındığını ve süreçteki değişimi değerlendirmektir. Çalışmada 30 gazete ve bu gazetelerdeki 210 manşet değerlendirilmiş olup, 98 (%46,6) manşet Düzce depremi ile ilgili olduğu görülmüştür. Afet yönetimi süreçlerine göre 46 (%46,9) manşet risk azaltma evresine yönelik, 35 (%35,7) manşet de kriz yönetimi evresine yönelik olarak bulunmuştur.

    The effects of COVID-19 process on health care workers: Analysing of the relationships between optimism, job stress and emotional exhaustion
    (Hipatia Press, 2020) Özdemir, Şefik; Kerse, Gökhan
    This research has focused on determining the levels of optimism, stress and emotional exhaustion of health care workers related to COVID-19 and the effect of optimism directly and indirectly (through job stress) on emotional exhaustion caused by Covid-19. The data were collected through an online questionnaire with optimism, job stress and emotional exhaustion scales arranged according to COVID-19. The data collected from 169 health care workers working in a city in Turkey were analysed using different statistical programs. The findings obtained has shown that the employees are quite optimistic in this process, and they have also experienced stress and emotional exhaustion even though their levels are lower than optimism. Also, it has been determined that being optimistic despite COVID-19 affects emotional exhaustion caused by COVID-19 both directly and indirectly through work stress. Therefore, the level of optimism in this process has reduced the emotional exhaustion caused by COVID-19; however, this decrease was felt stronger through stress. These findings have contributed to both healthcare managers and relevant official institutions, and to researches related to COVID-19.
