Sevinç Polat1,Behice Erci 한국간호과학회 2010 Asian Nursing Research Vol.4 No.3

Purpose The objective of this study was to adopt the Child Feeding Scale (CFS) to the Turkish language and culture and to assess the validity and the reliability of the Turkish version of the scale. Methods The research was methodological study design. A convenience sample of 158 mothers at a primary health care center completed a structured questionnaire including the CFS for mothers in 2008. Results In the assessment of construct validity, seven factors were identified; they related to Perceived Responsibility, Perceived Parent Weight, Perceived Child Weight, Concern About Child Weight, Pressure to Eat, Restriction, and Monitoring. The seven factors explained 57.6% of the total variance. The overall internal reliability coefficient of this scale was .75. Conclusions The present study provides evidence of the CFS’s validity and reliability. The scale has potential applications for use in research. The CFS can be used to assess aspects of child-feeding perceptions,attitudes, and practices and their relationships to children’s developing food acceptance patterns,the control of food intake and obesity.

Anti-tank impact absorption with a reinforced concrete plate design

Berivan Yilmazer Polat,Sedat Savas,Alper Polat Techno-Press 2023 Advances in concrete construction Vol.15 No.4

Anti-tank weapons are among the infantry weapons used by the armies of many countries. Anti-tank rockets and explosives such as TNT, generally used for armour piercing, are also frequently used in terrorist attacks. These attacks damage the protection facilities built from reinforced concrete. Rockets or similar explosives' rapid speed and burst temperatures pierce reinforced concrete during strikes, resulting in casualties and damage to crucial strategic structures. This study aimed to devise an economic and applicable reinforced concrete plate that could absorb the impact of anti-tank rockets and Trinitrotoluene (TNT) type explosives. Therefore, 5 different samples, produced from C50 reinforced concrete and 150×150 cm in size, were formed by combining plates of different numbers and thicknesses. Also, a sample, which was a single thick plate, was prepared. In destructive testing, Rocket Propelled Grenade (RPG-7) was used as the anti-tank rocket launcher. As a result of this study, the impact damage was reduced with hollow concrete plate geometries, and recommendations were developed for complete prevention.

Purpose: Midurethral synthetic slings for female stress urinary incontinence are minimally invasive polypropylene mesh tapes that are inserted under the midurethra with trocars. In the past decade, this new technology has become the most commonly performed procedure for female stress urinary incontinence, replacing the traditional open procedures. However, its effectiveness in pre- and postmenopausal women has not previously been compared. Materials and Methods: We assessed the clinical outcome of the transobturator tape (TOT) procedure in premenopausal (n=45) and postmenopausal (n=49) women by means of self-report and the Urinary Distress Inventory 6 (UDI-6) questionnaire. Results: The mean age of the pre- and postmenopausal women was 44 and 60 years, respectively. Mean parity was 2.4 and 3, respectively. There were no significant differences with respect to mean operation time, duration of hospitalization, or intraoperative and postoperative complications. However, premenopausal women were more satisfied with the operation than were postmenopausal women (p=0.014). Also, UDI-6 scores were significantly better in premenopausal women (p=0.027). Conclusions: The TOT operation appeared to be more effective in premenopausal women with stress urinary incontinence. However, further studies with larger sample sizes are needed to confirm our results.

Theoretical and Practical Changes in L2 Teacher Education : A Critical Review

Polat, Nihat 순천향대학교 인문과학연구소 2008 순천향 인문과학논총 Vol.22 No.-

A considerable number of recent studies have suggested that paradigmatic historical changes and challenges in different aspects of L2 teacher education have resulted in the acknowledgement (if its complex constituents and thereby the inclusion of more diachronic, holistic, multifaceted, eclectic, integrative and sometimes seemingly contentious approaches and conceptualizations. This critical review addresses the most recent changes and challenges in epistemological, theoretical, metho dological and practical aspects of L2 teacher education, It shows how researchers have taken different perspectives in categorizing and interpreting these perceptible transformations and challenges in L2 teacher education. Moreover, it addresses how several recent studies on L2 teacher education have pinpointed changes and challenges and how they have been translated into domains and competencies in second/foreign teacher education program requirements. A synthesis of these selected papers also delineates certain key themes that can help educators and researchers to better understand the future direction of second/foreign language education.

Examining dyadic conceptual elaboration regarding different group compositions in online asynchronous discussion

Polat Sendurur,Selcan Kilis 서울대학교 교육연구소 2023 Asia Pacific Education Review Vol.24 No.1

Grounded on cognitive elaboration theory, this study aims to investigate how students’ dyadic conceptual elaboration changed with different group compositions, namely presence/absence of instructor and unfamiliar students in online asynchronous discussion. Adopting a repeated measure experimental design, data were collected from third-year students from two universities attending a “Fundamentals of Distance Education” course. Through a free learning management system, asynchronous discussions with five different group compositions were held for six weeks. The transcripts of the online discussions were coded using thematic units. The data were analyzed using the Kruskal–Wallis H tests and Mann–Whitney U tests. The findings indicated that group compositions significantly affected students’ dyadic conceptual elaboration. The findings also revealed that increasing group heterogeneity was critical for students to generate new, valuable, and creative ideas. The study concludes the inclusion of instructors and unfamiliar learners in online asynchronous discussions for an enhanced dyadic conceptual elaboration.

Polat, Emre Can,Otunctemur, Alper,Ozbek, Emin,Besiroglu, Huseyin,Dursun, Murat,Ozer, Kutan,Horsanali, Mustafa Ozan Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.18

Background: We investigated the correlation between standardized uptake value (SUVmax), tumor size and Fuhrman grade in patients with renal cell carcinoma (RC). Materials and Methods: We retrospectively analyzed the data of 54 patients with clear cell renal cell carcinoma histopathologically diagnosed who underwent fluorine-18 fluoro-2 deoxyglucose positron emission tomography/computed tomography (F-18 FDG PET/CT) between January 2005 and March 2014. Results: Avarage tumor sizes were $5.64{\pm}1.85$, $6.85{\pm}2.24$ and $7.98{\pm}2.45$ in low, medium and high SUVmax groups, respectively. The Spearman's correlation coefficient between the tumor size and SUVmax was 0.385 (p=0.004) and between the Fuhrman grade and SUVmax was 0.578 (p<0.001). Conclusions: SUVmax appears highly correlated with tumor size and Fuhrman grade in patients with histopathologically confirmed clear cell RC. Multicenter studies are needed to provide larger series for more accurate results.

Polat, Fikriye,Diler, Songul Budak,Azazi, Irfan,Oden, Artun Asian Pacific Journal of Cancer Prevention 2015 Asian Pacific journal of cancer prevention Vol.16 No.6

The aim of the present study was to determine whether endothelial nitric oxide synthase (eNOS) gene polymorphisms play a role in development of bladder cancer in the Turkish population. The study was performed on 75 patients (64 men, 11 women) with bladder cancer and 143 healthy individuals (107 men, 36 women) with any kind of cancer history. Three eNOS gene polymorphisms (T-786C promoter region, G894T and intron 4 VNTR 4a/b) were determined with polymerase chain reaction and restriction fragment lenght polymorphism methods. In our study, GT and TT genotypes for eNOS G894T polymorphism were found to significantly vary among patients with bladder cancer and control group (OR: 0.185, CI: 0.078-0.439, p=0.0001 and OR: 0.324, CI: 0.106-0.990, p=0.026). Also, the frequency of the 894T allele was significantly higher in patients with bladder cancer (51%). No association was identified for eNOS T-786C and intron 4 VNTR 4a/b polymorphisms between patients with bladder cancer and control groups in our Turkish population.

Polat, Gunseli Guven,Yildirim, Ceren,Akgun, Ozlem Marti,Altun, Ceyhan,Dincer, Didem,Ozkan, Cansel Kose The Korean Academy of Conservative Dentistry 2014 Restorative Dentistry & Endodontics Vol.39 No.3

This study describes the treatment of an immature permanent tooth with periapical lesion which was treated with regenerative approach using platelet rich plasma (PRP). The root canal of immature human permanent tooth with periapical lesion was gently debrided of necrotic tissue and disinfected with 2.5% NaOCl, and then medicated with triple antibiotic paste comprised of ciprofloxacin, metronidazole, and tetracycline. When the tooth was asymptomatic, PRP and mineral trioxide aggregate (MTA) were placed into the root canal. Six months after PRP treatment, radiographical examination revealed resolution of the radiolucency and progressive thickening of the root wall and apical closure. Our findings suggest that PRP can be used for the treatment of immature permanent teeth with periapical lesion, as part of a regenerative endodontic treatment procedure.

Polat, Serdar,Cebe, Fatma,Tuncdemir, Aliriza,Ozturk, Caner,Usumez, Aslihan The Korean Academy of Prosthodonitics 2015 The Journal of Advanced Prosthodontics Vol.7 No.2

PURPOSE. The aim of this study was to evaluate effect of different surface treatment methods on the bond strength between aged composite-resin core and luting agent. MATERIALS AND METHODS. Seventy-five resin composites and also seventy-five zirconia ceramic discs were prepared. 60 composite samples were exposed to thermal aging (10,000 cycles, 5 to $55^{\circ}C$) and different surface treatment. All specimens were separated into 5 groups (n=15): 1) Intact specimens 2) Thermal aging-air polishing 3) Thermal aging- Er:YAG laser irradiation 4) Thermal aging- acid etching 5) Thermal-aging. All specimens were bonded to the zirconia discs with resin cement and fixed to universal testing machine and bond strength testing loaded to failure with a crosshead speed of 0.5 mm/min. The fractured surface was classified as adhesive failure, cohesive failure and adhesive-cohesive failure. The bond strength data was statistically compared by the Kruskal-Wallis method complemented by the Bonferroni correction Mann-Whitney U test. The probability level for statistical significance was set at ${\alpha}$=.05. RESULTS. Thermal aging and different surface treatment methods have significant effect on the bond strength between composite-resin cores and luting-agent (P<.05). The mean baseline bond strength values ranged between $7.07{\pm}2.11$ and $26.05{\pm}6.53$ N. The highest bond strength of $26.05{\pm}6.53$ N was obtained with Group 3. Group 5 showed the lowest value of bond strength. CONCLUSION. Appropriate surface treatment method should be applied to aged composite resin cores or aged-composites restorations should be replaced for the optimal bond strength and the clinical success.
