Active citizenship self-efficacy scale: A reliability and validity studyAktif yurttaşlık öz-yeterlik ölçeği: Bir geçerlik ve güvenirlik çalışması

The aim of this study is to develop a scale that measures active citizenship self-efficacy. Because self-efficacy identifies a person’s perceived beliefs towards his or her capacity and ability to succeed a task, it has a motivational and causative role in one’s possible acts or behaviors. For his reason, measuring active citizenship behaviors through self-efficacy is of special importance for understanding citizenry behaviors. The study explores the development of the Active Citizenship Self-Efficacy Scale (ACSES) and its psychometric properties. Participants consist of 414 university students, of which 326 were female and 88 were male. The validity of the scale was tested via explanatory and confirmatory factor analysis. The results for explanatory factor analysis with principal component solution indicated three factor structure that explains 57,17 percent of the total variance. Since the chi square test indicated that our data was meaningful, we also conducted a confirmatory factor analysis and found the indices of goodness of fit as for RMSEA = .070, GFI = .90, CFI = .97, NFI =.95, RFI = .95, AGFI = .87, IFI = .97 and NNFI = .96. These results from both explanatory and confirmatory factor analysis indicated that scale obtains construct validity criterion. The Cronbach alphas’ of the ACSES for the total 18 items and subdomains were found .90, and .84, .82, and .86 respectively. Since the determination of citizens’ self-efficacy level can in part reflect the results of citizenship education and practices we believe that this scale has a potential use in citizenship studies.Extended English abstract is in the end of PDF (TURKISH) file. ÖzetBu çalışmanın amacı aktif yurttaşlık öz yeterliği ile ilgili bir ölçme aracı geliştirmektir. Öz-yeterlik kişinin bir işi başarmada kendi kendisine yönelik algı inancını yansıttığı için olası davranışlar üzerine nedensel ve motivasyonel bir etkiye sahiptir. Bu nedenle, aktif yurttaşlık davranışlarını öz-yeterlik aracılığıyla ölçmek yurttaşlık davranışlarını anlamada önemlidir. Çalışmada Aktif Yurttaşlık Öz-yeterlik Ölçeği (AYÖYÖ) geliştirilerek psikometrik özellikleri tanıtılmıştır. Ölçek, 18 soru ve üç boyuttan meydana gelen bir ölçme aracıdır. Araştırmanın katılımcıları 326’sı kadın; 88’i erkek olmak üzere 414 üniversite öğrencisidir.  Elde edilen verilere açıklayıcı ve doğrulayıcı faktör analizi yapılarak ölçeğin geçerliliği test edilmiştir. Açıklayıcı faktör analizinde ölçeğin üç faktörlü yapısının toplam varyansı açıklama oranının % 57,17 olduğu görülmüştür. Doğrulayıcı faktör analizinde ki-kare değeri anlamlı bulunmuştur; uyum indeksleri ise RMSEA = .070, GFI = .90, CFI = .97, NFI =.95, RFI = .95, AGFI = .87, IFI = .97 ve NNFI = .96 olarak tespit edilmiştir. Bu sonuçlar, ölçeğin yapı geçerliğinin sağladığını göstermektedir. AYÖYÖ’nin tüm maddeler için Cronbach alpha güvenirlik katsayısı .90, alt boyutlar için ise .84, .82. ve .86  olarak tespit edilmiştir. Yurttaşların öz-yeterlik düzeylerinin tespit edilmesi yurttaşlık eğitimi ve uygulamalarının sonuçlarını görme açısından önemli olduğundan bu ölçme aracının yurttaşlık araştırmalarında yaygın kullanım potansiyeline sahip olduğunu düşünüyoruz

Evaluation of 86 Patients Whom Death While Being Followed up with Pre-Diagnosis of Covid-19

The Coronavirus-19 pandemic continues at full speed, and the number of patients who die from Covıd-19 is increasing. It was aimed to evaluate the demographic information and laboratory findings of 86 patients who died while being followed up in our hospital with a pre-diagnosis of Covıd-19. Identifying these characteristics of deceased patients will be essential to guide clinicians in identifying critically ill patients. Data on demographic information, comorbidities, time from hospitalization to death, molecular test results, thorax CT findings, biochemical findings, culture, antibiotic susceptibility, and the given treatments of the cases were collected from the electronic system Kastamonu Training and Research Hospital. While the RT-PCR test of 21 of the cases was positive, in 9 of the cases, control PCR tests were negative after a while. The CT results of 18 of the 21 initially RT-PCR positive cases were compatible with Covid-19, and the CT result of 3 could not be reached. When the blood test results of the cases were examined, neutrophil increase, white blood cell increase, lymphocyte reduction, and inflammatory markers increase were determined. A total of 43 bacterial growths were found in 21 cases. It has been observed that deaths in patients who were followed up with the pre-diagnosis of Covıd-19 generally occur in older people, males, and those with underlying diseases. It was thought that the cause of death could be underlying diseases, pathologies caused by inflammation, and secondary bacterial infections in addition to viral infection. Clinicians should be more careful about elderly patients, patients with secondary bacterial infections, or patients with neutrophilia, lymphopenia

Investigation of the effect of vitamin c and vitamin e on serum protein fractions in rats with experimental fluorosis

Bu çalışma, deneysel olarak kronik florozis oluşturulan ratlarda vitamin C (vit C) ve E (vit E)'nin serum protein fraksiyonları üzerindeki etkilerini araştırmak amacıyla planlandı. Materyal olarak Wistar-Albino ratlar kullanıldı (Her biri 8 rat içeren, 8 grup). Deneme grupları; kontrol grubu, deneysel florozis grubu, koruma grupları (16 hafta boyunca, içme suyu içeren günlük 150 ppm NaF içeren içme suyu/ad-libitum ile birlikte vit C (100 mg / kg), vit E (300 mg / kg) ve vit C + vit E (100 mg/kg + 300 mg/kg)) ve tedavi grupları (16 hafta boyunca 150 ppm NaF içeren içme suyu/ad-libitum verildikten sonra tedavi amacıyla 4 hafta vit C (100 mg/kg), vit E (300 mg / kg) ve vit C + vit E (100 mg/kg + 300 mg/kg)) olarak oluşturuldu. Deneme sonunda kan örnekleri toplandı ve serumlar alındı. Bu örneklerde serum protein fraksiyonları selüloz-asetat elektroforezi ile belirlendi. Deneysel florozis grubunda total protein yüzde gram açısından, alfa-1’in önemli oranda azaldığı ve beta globülinlerin arttığı tespit edildi. Korunma ve tedavi amacıyla vitamin C, vitamin E ve vitamin C+vitamin E birlikte verildiği gruplarda, değişen bu değerlerin kontrol grubuna yaklaştığı görüldü.The aim of the present study was to investigate the effects of vitamins C (vit C) and E (vit E) on the serum protein fractions in rats with experimentally-induced chronic fluorosis. Wistar-Albino rats (male) were used as material (8 groups, each containing 8 rats). The experimental groups were control, protection groups (daily 150 ppm NaF containing drinking water for 16 weeks as ad-libitum, and, on alternate Vit C (100 mg/kg), Vit E (300 mg/kg) and Vit C+ Vit E (100 mg/kg + 300 mg/kg) for 16 weeks) therapy groups (daily 150 ppm NaF containing drinking water for 16 weeks as ad-libitum, then normal drinking water as ad-libitum, Vit C (100 mg/kg), Vit E (300 mg/kg) and Vit C + Vit E (100 mg/kg + 300 mg/kg) on alternate for 4 weeks). The end of experimental period, blood samples were collected and serums were obtained. Serum protein fractions in blood samples were determined with cellulose-acetate electrophoresis. Alpha-1 was significantly decreased and beta globulins increased in the experimental fluorosis group. In the groups in which vitamin C, vitamin E and combine combination of vitamin C and vitamin E were given for prevention and treatment, it was observed that these changing values approach to the control group

The Effects of Lycopene Application on Sodium Fluoride (NaF) Applied Renal Cell Line

The present study was planned to investigate the potential protective properties of lycopene, an antioxidant carotenoid, on NaF applied renal cell line. NRK-52E cells were cultured under standard in vitro conditions with regular passages. 10.000 NRK-52E cells were planted in each culture platelet. Cells were incubated for 24 hours at 37°C in an incubator with CO2. After the incubation, the medium formed on the cells was removed and the prepared NaF and lycopene solutions were added. At least 4 wells were used for each dose. Culture vessels were incubated at 37°C in a CO2 incubator for 6, 12, and 24 hours for transformation of non-soluble formazan crystals by MTT stain and the MTT assay was conducted. In conclusion, it was found that low lycopene concentrations reduced the toxic effect of NaF by 10-20%, while lycopene increased the toxic effect of NaF synergistically in the high concentration lycopene treated groups. Thus, it was concluded that administration of lycopene on NaF applied renal cell line exhibited different effects based on concentration and duration

p-akriloiloksibenzoik asit ve p-metakriloiloksibenzoik asitin izotatik polipropilen üzerine aşı kopolimerleşmesi.

The monomers, p-acryloyloxybenzoic acid (ABA) and p-methacryloyloxybenzoic acid (MBA) were synthesized by condensation reaction of corresponding acid chlorides with p-hydroxybenzoic acid in alkaline medium. The polymerization of the monomers were studied by several techniques. Polyacryloyloxybenzoic acid (PABA) was obtained by ?-radiation induced, solution and bulk melt polymerization by initiation of dicumyl peroxide (DCP). Polymethacryloyloxybenzoic acid (PMBA) could be obtained by only bulk melt polymerization. The graft copolymerization of the monomers onto isotactic polypropylene, IPP, was successfully carried out only with bulk melt polymerization. The IPP used in the graft copolymerization was firstly subjected to ?-radiation to create active sites for grafting. The graft copolymerization of the monomers, ABA and MBA onto IPP were initiated by these active sites. The grafting was studied at constant concentration of the monomers in the reaction mixture (50%) and at different reaction temperatures (170, 185, 202, 215 and 225°C). The maximum grafting of PABA and PMBA were found to be 33.1% and 33.9% in the graft copolymers, respectively. The maximum grafting was reached in shorter times at higher temperatures, and it also increased with the increase of concentration of the monomers in the reaction medium. The graft copolymerization was also carried out by using initiator, DCP at 170°C, however, the grafting extent was lower due to the homopolymerization of the monomers and the direct reactions between peroxides of initiator and peroxides on IPP. The graft copolymers were characterized by several techniques, DSC, WAX, TG/IR, MS, SEM and mechanical testing. The formation of both crystalline forms of (?1 and ?2) were observed in the products obtained at 170°C. The graft copolymerization of ABA did not have any significance on the formation of both forms of ? form,Ph.D. - Doctoral Progra

INVESTIGATION OF SKID RESISTANCE PROPERTIES OF AGGREGATES USED IN AFYONKARAHISAR CITY PAVEMENTS

For a safe driving, pavement surface aggregates must have superior physical and mechanical properties. Although high rate of accidents is mainly due to drivers errors, pavement surface properties affect significantly occurance of traffic accidents. The most important factor in the highways leading to traffic accidents are the skid resistance. In this study, adherence test with Vialit plate, Nicholson stripping test, accelerated polishing test (PSV) were carried out on four aggregate samples which were used in seal coats and hot mix asphalt in Afyonkarahisar City. Results were compared with values of specification limits. The results showed that particularly limestone aggregates polishing stone values are poorer than volcanic aggregates sample. Especially, use of aggregates having a good polishing resistance, will be an important factor increasing driving safety

AFYONKARAHİSAR ŞEHİR İÇİ KAPLAMALARINDA KULLANILAN AGREGALARIN KAYMA DİRENCİ ÖZELLİKLERİNİN ARAŞTIRILMASI

Emniyetli bir sürüş güvenliği için yol üst yapılarının yüzeyinde kullanılan agregaların üstün fiziksel ve mekanik özelliklere sahip olması gerekmektedir. Kazaların çoğunluğu sürücü hatalarından kaynaklanmakla birlikte, yol kaplamasının yüzey özellikleri, kazaların oluşmasında önemli pay sahibidir. Yol kaplamalarının trafik kazalarına etki eden en önemli özelliği yol yüzeyinin kayma direncidir. Bu çalışmada Afyonkarahisar bölgesi sıcak karışım asfalt betonu ve sathi kaplamalarında kullanılan dört farklı agrega üzerinde soyulma, yapışma ve hızlandırılmış cilalanma deneyleri yapılmış ve sonuçlar karşılaştırmalı olarak verilmiştir. Çalışmanın sonucu kireç taşı kökenli agregaların özellikle cilalanma değerleri volkanik kökenli agrega numunesine göre daha zayıf olduğunu göstermiştir. Özellikle aşınma tabakalarında cilalanma direnci daha yüksek agregaların kullanılması sürüş emniyetini arttırıcı bir unsur olacaktır
