Ertuğ,rul Onalp 한국중동학회 2009 韓國 中東 學會 論叢 Vol.30 No.2

오스만제국은 홍해에서의 안보를 확보하기 위해서 포루투갈과 전투를 전개할 의도로 1525 년에 스웨즈 지역에 해양 기지를 세웠다. 이 해양 기지의 사령관으로 1547 년 피리 레이스(Piri Reis)가 임명되었다. 피리 레이스는 술탄 술에이만의 명령을 받아서 호르무즈 지역을 점령하기 위해 스웨즈에서 함대를 지휘해 바스라 지역으로 향했다. 피리 레이스는 바스라 지역에서 1 만 오천 명의 군병과 다수의 함정의 지원을 받아서 호르무즈 지역을 점령해야 했었다. 그러나 피리 레이스는 바스라에 접근하기 전에 지원병의 도움을 받지 않고 호르무즈 성을 포위했다. 호르무즈 성에 진을 치고 있던 포르투갈 주둔군은 피리 레이스 함대의 포위와 공격을 막아낼 수 있었다. 피리 레이스는 호루무즈 성을 점령할 가능성이 없음을 파악하고 포위 공격을 포기하고 바스라 지역으로 후퇴했다. 그 뒤에 스웨즈로 귀한하기 위해 3 척의 함대로 바스라를 출발했다. 그러나 피리 레이스는 이집트로 귀환했을 때 술탄의 명을 성공적으로 실현하기 못했으므로 체포돼 교수형에 처해 졌다. 술탄 술레이만은 바스라에 정박해 있던 21 척의 함선 가운데 7 척을 할당해서 대 사파위 조 전투에 활용하도록 했으며, 나머지 함선을 스웨즈로 이동하도록 명을 내렸다. 이 임무를 받은 무라트 베이(Murat Bey)는 바스라 만에서 포르투갈 함대와 벌어진 전투에서 별다른 성과를 거두지 못하고 바스라도 돌아갔다. 무라트 베이가 실패하자 세이디 알리 레이스가 술탄의 명을 이행하도록 지명되었다. 그러나 세이디 알리 레이스도 포르투갈과의 전투에서 6 척의 함성을 잃었으며 그 밖에 함선을 규자랏(Gucarat) 항만에 정박시키게 되었다. 이 글에서는 세이디 알리 레이스(Seydi Ali Reis) 측과 포르투갈 함대 간에 있었던 전투의 특징과 과정을 분석하였다.

Detailed Magnetic Force Analysis of A 4-Pole Hybrid Electromagnet by Magnetic Equivalent Circuit Method

Hasan Fatih Ertu?rul,Kadir Erkan,Huseyin Uvet Korean Magnetics Society 2018 Journal of Magnetics Vol.23 No.4

In this paper, detailed magnetic force analysis of a 4-pole hybrid electromagnet system providing an advantage of full-redundant levitation is studied. The novel fragmented magnetic equivalent circuit method (MEC) is developed to accurately capture inherited nonlinear characteristics of 4-pole hybrid electromagnet to investigate force characteristics and magnetic field distribution. To confirm this method, two possible scenarios, which are levitation under plain core and levitation under dual-linear motor are composed. As well as, they are examined by both proposed method and FEM analyses. Comparative analyses of both methods revealed that force, inclination torque, and mutual interference can be easily captured with adequate accuracy while at the same time yielding less computation and set up time. Furthermore, the fragmented formulations of permeance functions can be generalized for the analysis and the design of similar devices which specifically involve inclination motions.

Physiological and Biochemical Changes in Lucerne (Medicago sativa) Plants Infected with ‘Candidatus Phytoplasma australasia’-Related Strain (16SrII-D Subgroup)

Hü,meyra Ayvacı,M. Ertuğ,rul Gü,ldü,r,Murat Dikilitas 한국식물병리학회 2022 Plant Pathology Journal Vol.38 No.2

Changes in physiological and biochemical patterns in lucerne plants caused by the presence of ‘Candidatus Phytoplasma australasia’, which is one of the significant pathogens causing yield losses in lucerne plants, were investigated. Significant differences were evident in total chlorophyll, chlorophyll a, chlorophyll b, and protein amounts between ‘Ca. Phytoplasma australasia’- positive and negative lucerne plants. Stress-related metabolites such as phenol, malondialdehyde, and proline accumulations in ‘Ca. Phytoplasma australasia’- positive plants were remarkably higher than those of phytoplasma-negative plants. As a response to disease attack, phytoplasma-positive plants exhibited higher antioxidant enzymes (peroxidase and catalase) and nonenzymatic metabolite responses such as jasmonic and salicylic acids. We state that partial disease responses were revealed for the first time to breed resistant lucerne lines infected by ‘Ca. Phytoplasma australasia’.

Gül Esra,Babaroğlu Numan Ertuğrul,Demirci Fikret 한국응용곤충학회 2021 Journal of Asia-Pacific Entomology Vol.24 No.2

The sunn pests (Eurygaster spp.) which are important pests of wheat and barley, can lead to 100% yield loss in the case of an epidemic. This study was conducted to characterize the entomopathogenic fungi, obtained from the sunn pests collected from different overwintering areas of Turkey and determine their pathogenicity. Seventeen Beauveria pseudobassiana, 12 Beauveria bassiana, 16 Cordyceps farinosa, 1 Purpureocillium lilacinum, and 2 Clo nostachys rosea species were identified. Pathogenicity tests were performed with three B. pseudobassiana, two B. bassiana, four C. farinosa, and one P. lilacinum isolates. B. pseudobassiana isolates BB34 and AF4 caused 100% death on the 9th day, and another B. pseudobassiana isolate E512 caused 100% death on the 12th day. C. farinosa isolate KOKA2 caused 95.8% death on the 15th day. Ultimately, B. pseudobassiana was determined to be the most prevalent and virulent species on sunn pests.

Transformation of marriage migrants to diasporic actors and rethinking female agency: Ukrainian women in Türkiye

Deniz Ayla,Özgür Ertuğrul Murat 이화여자대학교 아시아여성학센터 2024 Asian Journal of Women's Studies(AJWS) Vol.30 No.1

This article investigates the transformation of Ukrainian female marriage migrants in Türkiye into diasporic actors. This role as diasporic actors represents a unique aspect of female agency, and its impact on migrant women and the diaspora is discussed. The representatives of the hometown associations (HTAs) were interviewed, the activities of the HTAs were tracked, and their social media posts were examined. The findings reveal that when women became diasporic actors, they influenced community politics on a large scale and created multiple networks. It has also been found that migrants strengthened the institutional structures of the HTAs by using these networks. Moreover, through their approach of bringing different groups together, they created a diaspora composition where hierarchy in representation is not explicit.

An analysis of user behaviors on the search engine results pages based on the demographic characteristics

( Yıltan Bitirim ),( Duygu Çelik Ertuğrul ) 한국인터넷정보학회 2020 KSII Transactions on Internet and Information Syst Vol.14 No.7

The purpose of this survey-based study is to make an analysis of search engine users’ behaviors on the Search Engine Results Pages (SERPs) based on the three demographic characteristics gender, age, and program studying. In this study, a questionnaire was designed with 12 closed-ended questions. Remaining questions other than the demographic characteristic related ones were about “tab”, “advertisement”, “spelling suggestion”, “related query suggestion”, “instant search suggestion”, “video result”, “image result”, “pagination” and the amount of clicking results. The questionnaire was used and the data collected were analyzed with the descriptive statistics as well as the inferential statistics. 84.2% of the study population was reached. Some of the major results are as follows: Most of each demographic characteristic category (i.e. female, male, under-20, 20-24, above-24, English computer engineering, Turkish computer engineering, software engineering) have rarely or more click for tab, spelling suggestion, related query suggestion, instant search suggestion, video result, image result, and pagination. More than 50.0% of female category click advertisement rarely; however, for the others, 50.0% or more never click advertisement. For every demographic characteristic category, between 78.0% and 85.4% click 10 or fewer results. This study would be the first attempt with its complete content and design. Search engine providers and researchers would gain knowledge to user behaviors about the usage of the SERPs based on the demographic characteristics.

Yavuz Yücel,Salih Coşkun,Beyhan Cengiz,Hasan H. Özdemir,Ertuğrul Uzar,Abdullah Çim,M. Akif Camkurt,M. Ufuk Aluclu 대한정신약물학회 2016 CLINICAL PSYCHOPHARMACOLOGY AND NEUROSCIENCE Vol.14 No.3

Objective: Migraine, a highly prevelant headache disorder, is regarded as a polygenic multifactorial disease. Serotonin (5-HT) and their respective receptors have been implicated in the patogenesis. Methods: We investigated the 5-HT1A, 5-HT1B, 5-HT2A, and 5-HT2C receptor gene polymorphisms and their association with migraine in Turkish patients. The rs6295, rs1300060, rs1228814, rs6311, rs6313, rs6314, rs6318, rs3813929 (-759C/T) and rs518147 polymorphisms were analyzed in 135 patients with migraine and 139 healthy subjects, using a BioMark 96.96 dynamic array system. Results: We found no difference in the frequency of the analyzed eight out of nine polymorpisms between migraine and control groups. However, a significant association was found between the rs3813929 polymorphism in the promoter region of 5-HTR2C gene and migraine. Also, the allele of rs3813929 was more common in the migraine group. Conclusion: This result suggests that the 5-HTR2C rs3813929 polymorphism can be a genetic risk factor for migraine in a Turkish population.

Gingival crevicular fluid CSF-1 and IL-34 levels in patients with stage III grade C periodontitis and uncontrolled type 2 diabetes mellitus

Ahu Dikilitaş,Fatih Karaaslan,Şehrazat Evirgen,Abdullah Seçkin Ertuğrul 대한치주과학회 2022 Journal of Periodontal & Implant Science Vol.52 No.6

Purpose: Periodontal diseases are inflammatory conditions that alter the host’s response to microbial pathogens. Type 2 diabetes mellitus (T2DM) is a complex disease that affects the incidence and severity of periodontal diseases. This study investigated the gingival crevicular fluid (GCF) levels of colony-stimulating factor-1 (CSF-1) and interleukin-34 (IL-34) in patients with stage III grade C periodontitis (SIII-GC-P) and stage III grade C periodontitis with uncontrolled type 2 diabetes (SIII-GC-PD). Methods: In total, 72 individuals, including 24 periodontally healthy (PH), 24 SIII-GC-P, and 24 SIII-GC-PD patients, were recruited for this study. Periodontitis patients (stage III) had interdental attachment loss (AL) of 5 mm or more, probing depth (PD) of 6 mm or more, radiographic bone loss advancing to the middle or apical part of the root, and tooth loss (<5) due to periodontal disease. Radiographic bone loss in the teeth was also evaluated; grade C periodontitis was defined as a ratio of the percentage of root bone loss to age greater than 1.0. The plaque index (PI), gingival index (GI), presence of bleeding on probing (BOP), PD, and clinical AL were used for clinical periodontal assessments. GCF samples were obtained and analyzed using an enzyme-linked immunosorbent assay. Results: All clinical parameters—PD, AL, GI, BOP, and PI—were significantly higher in the SIII-GC-PD group than in the PH and SIII-GC-P groups for both the full mouth and each sampling site (P<0.05). The total IL-34 and CSF-1 levels were significantly higher in the SIII-GC-PD group than in the PH and SIII-GC-P groups (P<0.05), and there were significant differences between the periodontitis groups (P<0.05). Conclusions: These findings suggest that IL-34 and CSF-1 expression increases in patients with SIII-GC-PD. CSF-1 was associated with the inflammatory status of periodontal tissues and T2DM, while IL-34 was associated only with T2DM.
