Türk sürücülerinin kendi bildirimlerine dayanan trafik ihlalleri ve riskli sürüş tutumlari: Eskişehir örneği

Risky driving attitude terminology is used to explain behaviors, which directly increase accident risk, such as over speeding or violation to traffic rules while driving and attitudes related to traffic safety. This study is focused on driver factors in traffic accidents and was carried out in order to show risky drivers' attitudes tendency, especially. In this study, in order to develop a risky driver attitude model, factors explaining obedience to speed rules, caring about traffic accidents, risk taking tendency in traffic and violations of basic traffic rules were studied. For this reason with the assistance of structural equation models LISREL 8.54 was used to try to develop a model, and fitness of the model has been discussed considering various fitness criteria. On the other hand, analysis of variance was performed for factors measuring sex, education level, age and driving experience, in order to portrait risky drivers.Riskli sürücü tutumu terminolojide, trafik güvenliğiyle ilgili sürüş, tutumlar, trafik kural ihlalleri veya hızlı sürüş gibi kaza riskini doğrudan arttıran davranışları açıklamak için kullanılmaktadır.

Rüzgar hızı dağılımının tahmin edilmesi için istatistiksel bir yaklaşım: Gelibolu bölgesi örneği

Wind energy is renewable and environment friendly. It is an alternative clear energy source compared to the fossil fuels that pollute the lower layer of atmosphere. The most important parameter of the wind energy is the wind speed. Statistical methods are useful for estimating wind speed because it is a random phenomena. For this reason, wind speed probabilities can be estimated by using probability distributions. An accurate determination of probability distribution for wind speed values is very important in evaluating wind speed energy potential of a region. In this study, first, we tried to determine appropriate theoretical pdf (probability density function) by comparing 10 pdf for the wind speed data measured for Gelibolu region. In determining proper pdf , an approach consisting of 3 goodness of fit tests and fitted graphics have been used.Rüzgar enerjisi yenilenebilir ve çevre dostu bir enerjidir. Rüzgar enerjisi atmosferi kirleten fosil yakıtlarıyla kıyaslandığında, temiz enerji kaynağı için bir alternatiftir. Rüzgar enerjisinin potansiyelinin en önemli parametresi rüzgar hızıdır. Rüzgar hızı rassal olay olarak tanımlandığı için rüzgar hız tahminlerinde istatistiksel yöntemleri kullanmak yararlıdır. Bu nedenle rüzgar hızı, olasılık dağılımları kullanılarak tahmin edilebilir. Bir bölgenin rüzgar hızı enerji potansiyelinin değerlendirilmesi ve tahmini için geçerli bir olasılık dağılımının belirlenmesi çok önemlidir. Bu çalışmada Gelibolu bölgesinde ölçülen rüzgar hızı verilerini temsil edebilecek uygun bir olasılık dağılımı 10 dağılım karşılaştırılarak belirlenmeye çalışılmıştır. Bu amaçla üç uyum iyiliği testi ve grafik yöntemi kullanılmıştır

SERVQUAL Scale was conducted to 90 people who get service from X Tax Chambers between April-May 2016. As a result of the SERVQUAL analysis, the research reveals that the taxpayers of the X Tax Chambers are not satisfied with the service quality and the most difference between expected service quality and perceived service quality is accessibility dimension. The research indicates no significant differences between expactations for service provided and demographics features. However the research shows significant differences between service perceptions and demographics features

Sporadic Nonautoimmune Neonatal Hyperthyroidism Due to A623V Germline Mutation in the Thyrotropin Receptor Gene

Neonatal hyperthyroidism is a rare disorder and occurs in two forms. An autoimmune form is associated with maternal Graves' disease, resulting from transplacental passage of maternal thyroid−stimulating antibodies and a nonautoimmune form is caused by gain of function mutations in the thyrotropin receptor (TSHR) gene. Thyrotoxicosis caused by germline mutations in the TSHR gene may lead to a variety of clinical consequences. To date, 55 activating mutations of the TSHR gene have been documented. Fourteen cases with sporadic activating TSHR germline mutations have been described. Here we report a male infant with nonautoimmune hyperthyroidism due to an activating germline TSHR mutation (A623V), whose clinical picture started in the newborn period with severe hyperthyroidism. His parents did not have the same mutation. This mutation had been previously detected as a somatic mutation in patients with toxic adenomas. This is the first report of a sporadic case of nonautoimmune congenital hyperthyroidism associated with A623V mutation

Hypothyroidism Due to Hepatic Hemangioendothelioma: A Case Report

Although hemangioendothelioma (HHE) is a commonly encountered hepatic tumor during infancy, HHE−related hypothyroidism is rare. We present a patient who developed HHE−related hypothyroidism during the neonatal period and showed marked improvement in hypothyroidism by regression of HHE. A 28−day−old boy with TSH level of 77 mIU/mL on neonatal screening and diagnosed as congenital hypothyroidism was started on L−thyroxine (L−T4) (11 μg/kg/day) therapy on the 21th day of life. On physical examination, the liver was palpable 5 cm below the right costal margin, and the thyroid gland was nonpalpable. Thyroid ultrasonography was normal. Although L−T4 dose was increased to 15 μg/kg/day, TSH was not suppressed and free T3 level remained low. HHE in both lobes of the liver was detected by abdominal ultrasonography and magnetic resonance imaging. Treatment was started with prednisolone 2 mg/kg/day and alpha−interferon 3 million U/m2/3 times per week. Thyroid dysfunction was thought to be due to type 3 iodothyronine deiodinase activity expressed by HHE. L−T4 therapy was changed to Bitiron® tablet, which includes both T4 and T3, and euthyroidism was attained within 1 month. Thyroid hormone requirement was reduced and treatment was discontinued after regression of the HHE. At the most recent visit, the patient was 21 months old and off treatment. His growth and neurological development were normal for age and he was euthyroid. HHE should be considered in cases with severe hypothyroidism resistant to high−dose thyroid hormone replacement. The treatment of HHE in combination with T4 and T3 therapy results in euthyroidism

Insulin Oedema in Newly Diagnosed Type 1 Diabetes Mellitus

Despite the essential role of insulin in the management of patients with insulin deficiency, insulin use can lead to adverse effects such as hypoglycaemia and weight gain. Rarely, crucial fluid retention can occur with insulin therapy, resulting in an oedematous condition. Peripheral or generalised oedema is an extremely rare complication of insulin therapy in the absence of heart, liver or renal involvement. It has been reported in newly diagnosed type 1 diabetes, in poorly controlled type 2 diabetes following the initiation of insulin therapy, and in underweight patients on large doses of insulin. The oedema occurs shortly after the initiation of intensive insulin therapy. We describe two adolescent girls with newly diagnosed type 1 diabetes, who presented with oedema of the lower extremities approximately one week after the initiation of insulin treatment; other causes of oedema were excluded. Spontaneous recovery was observed in both patients

Total bilirubin and fasting plasma glucose levels are associated with coronary collateral development in elderly patients

Background and objective: We aimed to investigate biochemical factors affecting coronary collateral circulation development in an elderly population aged 75 years and over. Material and methods: The study group consisted of patients with a prior coronary angiography for stable coronary artery disease (CAD). Patients with total occlusion of at least one vessel were included in the study. Enrolled patients were divided into two groups, good collateral (GC; n = 73) and bad collateral (BC; n = 55), in accordance with the Cohen-Rentop’s classification system. Results: In comparison to the GC group, bilirubin levels were significantly lower (p < 0.001), and fasting plasma glucose (FPG) levels were significantly higher in the BC group (p = 0.026). Low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C) levels were significantly lower in the BC group when compared to the GC group (p = 0.002 and p < 0.001, respectively). Backward elimination stepwise logistic regression analysis identified bilirubin and FPG as variables that strongly predicted the presence of a well-developed coronary collateral circulation and a poorly developed coronary collateral circulation, respectively. Conclusion: Bilirubin and FPG were seemed as the most important factors affecting coronary collateral circulation development in patients with stable CAD who were older than 75 years

Tekstil sektöründe Avrupa Birliği IPPC direktifi ile uyum çalışmaları: BAT uygulamaları

TÜBİTAK ÇAYDAG15.01.2008Bu çalışma, Türkiye'de bir tekstil işletmesi için IPPC (Entegre Kirlilik Önleme ve Kontrolü) Direktifi kapsamında "Mevcut En İyi Teknikler"in ilk uygulaması ve değerlendirmesidir. IPPC Direktifi'nin hayata geçirilmesinde rehber olacak bir "en iyi uygulama örneği" tekstil sektörü için geliştirilmiş ve bu kapsamda işletme için "Mevcut En İyi Teknik" ihtiyaçları belirlenmiştir. Sürdürülebilir hammadde ve atık yönetimi için, ilk olarak, üretim süreçlerinin BREF ("Mevcut En İyi Teknikler" Referans) Dokümanı ile detaylı karşılaştırılması yapılmıştır. Su yoğun bir sektör olması sebebiyle, proseslerde geri kullanımı mümkün olabilecek atıksular belirlenip atıksu karakterizasyon çalışmaları yürütülmüştür. Proses atıksularında ve tesisten çıkan toplam atıksuda geri kazanım olanaklarının araştırılması için atıksu yönetim stratejisi oluşturulmuştur. Bu stratejiyle uyumlu olarak, üretim süreçlerinin BREF Tekstil Dokümanı ile detaylı karşılaştırılması yapılmış, gerek atıksuların geri kullanım amaçlı arıtılabilirliği gerekse su kullanımının ve atıksu üretiminin azaltımı üzerine çalışılmıştır. Uygulanabilir BAT önerileri fabrika yetkilileri ile birlikte çalışarak belirlenmiştir. Atıksu yönetimi çalışmalarının yanı sıra, enerji tüketiminin azaltılması, kimyasal değişikliği ve çevresel risk analizi çalışmaları da yürütülmüştür.This study was undertaken as the first application and evaluation of Best Available Techniques (BAT) within the context of the IPPC (Integrated Pollution Prevention and Control) Directive to a textile mill in Turkey. A “best practice example”, which will form a guideline for the implementation of the IPPC Directive, is to be developed for the textile sector; and within this context BAT requirements for the mill were determined. In order to achieve a sustainable resource and waste management; firstly, a detailed screening of the production processes with respect to BREF (BAT Reference) Textile Document was made. Being a water intensive sector, wastewater characterization study was conducted to identify the possible candidate wastewaters to be reused. A wastewater management strategy was adopted to investigate the possible reuse opportunities in the process wastewaters along with the composite mill effluent. In line with this strategy, production processes were analyzed in depth in accordance with the BREF Document not only to treat the generated wastewaters for their possible reuse but also to reduce the amount of water consumption and wastewater generation. Applicable BAT options were determined in cooperation with the mill staff. Besides studies related to wastewater management, minimization of energy consumption, chemical substitution and environmental risk analysis studies were also conducted

Outcomes of high-risk breast lesions diagnosed using image-guided core needle biopsy: results from a multicenter retrospective study

PURPOSEThe clinical management of high-risk lesions using image-guided biopsy is challenging. This study aimed to evaluate the rates at which such lesions were upgraded to malignancy and identify possible predictive factors for upgrading high-risk lesions.METHODSThis retrospective multicenter analysis included 1.343 patients diagnosed with high-risk lesions using an image-guided core needle or vacuum-assisted biopsy (VAB). Only patients managed using an excisional biopsy or with at least one year of documented radiological follow-up were included. For each, the Breast Imaging Reporting and Data System (BI-RADS) category, number of samples, needle thickness, and lesion size were correlated with malignancy upgrade rates in different histologic subtypes. Pearson’s chi-squared test, the Fisher–Freeman–Halton test, and Fisher’s exact test were used for the statistical analyses.RESULTSThe overall upgrade rate was 20.6%, with the highest rates in the subtypes of intraductal papilloma (IP) with atypia (44.7%; 55/123), followed by atypical ductal hyperplasia (ADH) (38.4%; 144/375), lobular neoplasia (LN) (12.7%; 7/55), papilloma without atypia (9.4%; 58/611), flat epithelial atypia (FEA) (8.7%; 10/114), and radial scars (RSs) (4.6%; 3/65). There was a significant relationship between the upgrade rate and BI-RADS category, number of samples, and lesion size Lesion size was the most predictive factor for an upgrade in all subtypes.CONCLUSIONADH and atypical IP showed considerable upgrade rates to malignancy, requiring surgical excision. The LN, IP without atypia, pure FEA, and RS subtypes showed lower malignancy rates when the BI-RADS category was lower and in smaller lesions that had been adequately sampled using VAB. After being discussed in a multidisciplinary meeting, these cases could be managed with follow-up instead of excision
