Ultra-lightweight stream ciphers are highly optimized variation of stream ciphers for miniscule hardwares with limited power and calculation resources such as RFID product tags used in retail marketing and Wireless Sensor Network components that are indispensable part of modern SCADA systems. In FSE 2015, Armknecht and Mikhalev presented a unique ultra-lightweight stream cipher design approach defined as Keystream Generators with Keyed Update Function (KSG with KUF) along with a concrete cipher Sprout [1]. This design approach used by recent stream ciphers such as Fruit [2] and Plantlet [3], promises to make use of secret key during state updates in order to maintain security level as well as shorten internal state size to reduce hardware area in conjunction with power consumption. In 2018, definition of KSG with KUF is narrowed by Kara and Esgin [4], with new definition Keystream Generators with Boolean Keyed Feedback Function (KSG with Boolean KFF), on which a generic scope trade-off attack is also mounted. This attack relies on guess capacity definition given in the same article, to eliminate wrong states during exhaustive search operation. In this thesis, we examined this generic Kara and Esgin attack in-depth and accelerated by a factor up to about 60 times. In order to accomplish this speedup, a new guess capacity definition and sieving method are introduced in addition to the improved algorithm which contributes efficiency of the attack in both performance and stability. Improvements are validated with intense performance tests comprising nearly twenty sample feedback functions, including Sprout, with diverse existence of guess capacities.Yazarlık Beyanı ii Abstract

Investigation of the Mechanical, Electronic and Phonon Properties of X2ScAl (X = Ir, Os, and Pt) Heusler Compounds

In the present study, the second-order elastic constants and the electronic band structures of the X2ScAl (x = Ir, Os, and Pt) compounds crystallized in the L21 phase were calculated separately by using the ab-initio density functional theory. According to the results for the second-order elastic constants, these compounds met the Born mechanical stability criteria. Also, according to the Pugh criteria, they were found to have a ductile structure and to show anisotropic behavior. The microhardneses of the compounds were between 2 and 14 GPa, and the highest hardness was found in the Ir2ScAl (14.290 GPa) compound. In addition, the energy band structures of these compounds were calculated, and the crystals were found to have a metallic bond structure. All the computed data were compared with previously calculated results obtained with different methods. According to the findings obtained in the present study, in terms of its mechanical and electronic behaviors, Ir2ScAl was found to have better physical properties than Os2ScAl and Pt2ScAl. The phonon dispersion curves and their corresponding total and projected densities of states were investigated for the first time by using a linear-response approach in the context of density functional perturbation theory. The frequencies of the optical phonon modes of all compounds at the Γ point were 4.767, 7.504 and 9.271 THz for Ir2ScAl, 2.761, 7.985 and 9.184 THz for Os2ScAl and 2.012, 5.6952 and 8.118 THz for Pt2ScAl. The heat capacity Cv at constant volume versus temperature was calculated using a quasi-harmonic approach and the results are discussed. © 2020, The Korean Physical Society

The relationship between myocardial perfusion scanning results, C-reactive protein to albumin ratio, systemic inflammatory response index and coronary angiographic findings

Aim: We aimed to investigate whether C-reactive protein to albumin ratio (CAR) and systemic inflammatory response index (SIRI) have an additional value in interpretation of myocardial perfusion scanning (MPS) results. Background: MPS have high sensitivity but relatively low specificity in diagnosis of coronary artery disease (CAD). Material and methods: 449 patients who had MPS before coronary angiography were included.  Patients with and without CAD constituted study (n=227) and control (n=222) groups, respectively. Results: Sensitivity and specificity of MPS in detecting CAD were found to be as 97.8% and 62.2%, respectively.  CAR value of 1.22 and SIRI value of 1.45 predicted CAD with a sensitivity of 61.2% and 59% and specificity of 77% and 80.2%, respectively. Only 10.4 % of the CAD negative patients had positive MPS and positive CAR values, whereas 0.9% of the CAD positive patients had negative MPS and negative CAR values.  27.5% of CAD negative patients had positive MPS and negative CAR values. Likewise, having a negative MPS with negative SIRI value identified 50% of the patients who had normal coronary arteries. Positive MPS with positive SIRI value correctly identified 58.1% of patients who had CAD. Conclusion: evaluation of CAR and SIRI might be beneficial in interpretation of MPS

The effects of Coronavirus disease-2019 (COVID-19) pandemic on routine antenatal care visits and complications of pregnancy

OBJECTIVE: Routine follow-up of pregnancy is a comprehensive care process starting from planning of pregnancy that involves rational and careful use of medical, psychological, and social support. In this study, our objective was to compare the adherence rate to routine antenatal follow-up program during the COVID-19 pandemic with that of previous years among pregnant women, in an effort to shed light on health policies to be developed similar events in the future. METHODS: This retrospective cross-sectional study was carried out between March 11, 2019, when isolation measures were initiated in the context of precautionary steps taken in Turkey against the COVID-19 pandemic, and June 1, 2020, when the "normalization" was initiated. RESULTS: During the study period in 2020, the proportion of cesarean sections were higher, 61.1%, as compared to previous years (p=0.27). The stillbirths were numerically lower (1.2%, p=0.77), but the rate of spontaneous abortions was significantly higher (19.6%, p=0.009). The number of follow-up visits per pregnancy was lower than in previous years (3.8, p=0.02), although the proportion of patients visiting the outpatient units for regular controls to the overall patient group increased as compared to previous years (52.0%). CONCLUSION: During the flare-up of the COVID-19 pandemic (i.e. between March and June 2020), the rate of obstetric/neonatal morbidity and mortality except spontaneous abortion was not significantly higher as compared to the corresponding period in previous years. However, considering the potential increase in the risk of obstetric complications during a pandemic, specialized management programs targeting basic pregnancy follow-up services should be developed

The use of complementary and alternative medicine in children followed by asthma diagnosis and attitudes of families

Amaç: Astım, yaşam kalitesini etkileyen, hava yolu aşırı duyarlılığıyla ilişkili kronik hava yolu inflamasyonu ile karakterize bir hastalıktır. Astım tedavisinde dünya genelinde kabul görmüş tedavi kılavuzları olmasına rağmen çoğu hasta, hem tedavi sırasında yaşanan sıkıntılar ve yan etki korkuları hem de uzun süreli ilaç kullanma gibi nedenlere bağlı olarak Tamamlayıcı ve Alternatif Tıp (TAT) yöntemlerini tercih edebilmektedir. Bu çalışmada astım tanısı ile takip edilen çocuklarda tamamlayıcı alternatif tıp kullanımının ve ailelerin tutumlarının belirlenmesi amaçlanmıştır. Materyal ve Metot: Tanımlayıcı nitelikteki araştırma 3-17 yaş arasındaki astım tanılı çocuklarda gerçekleştirilmiştir. Hasta yakınlarına, kullandıkları TAT yöntemlerini belirlemek amacıyla anket formu uygulanmıştır. Ailelerinin tutumlarını tespit edebilmek için Bütüncül Tamamlayıcı ve Alternatif Tıbba Karşı Tutum Ölçeği uygulanmıştır. Bulgular: Aileler tarafından TAT yöntemlerinin en sık “Hastalık ile savaşmak için mümkün olan her şeyi yapmak” (%46,46) amaçlı tercih edildiği ve bu bilgiyi “aile üyeleri/ arkadaş/komşu/yakınların” önerisi (%56,30) ile uyguladıkları belirlendi. TAT yöntemlerini %66,53 oranında 1-6 ay arasında kullandıkları ve bu yöntemin kullanımının %53,94 oranında tedavide başarı sağladığını düşündükleri bulundu. Medikal tedaviden memnuniyetsizlik ve ümitsizlik yaşayan ailelerin ortanca 25 (20-39) puan ile tamamlayıcı ve alternatif tıbba karşı pozitif tutumlarının arttığı ve istatistiksel olarak anlamlı olduğu belirlendi (p=0,035). Sonuç: Çocuklarında astım hastalığı olan ailelerin TAT kullanım oranlarının yüksek olduğu ve TAT kullanımına yönelik pozitif tutum sergiledikleri bulunmuştur. Giderek artan oranlarda TAT kullanımı, sağlık çalışanlarının da bu konuda bilgi sahibi olma ihtiyacını ortaya koymaktadır.Objectives: Asthma is a disease that affects the quality of life and is characterized by chronic airway inflammation associated with airway hypersensitivity. Although there are worldwide accepted treatment guidelines in the treatment of asthma, most patients use Complementary and Alternative Medicine (CAM) methods for many reasons, such as both insufficiencies in treatment and fears of side effects and long-term medication. This study aimed to determine the use of complementary & alternative medicine and the attitudes of families in children followed with the diagnosis of asthma. Materials and Methods: This descriptive study was carried out in children diagnosed with asthma between the ages of 3-17. A questionnaire was applied to the patients' relatives to determine CAM methods. The Holistic CAM Questionnaire was applied to determine the attitudes of their families. Results: It was determined by families that they prefer using CAM to “Do everything possible to fight the disease” (46.46%) and use this information with the recommendation “Family members/friends/neighbors/relatives” (56.30%). It was found that they used CAM methods 66.53% between 1-6 months, and they thought that the use of the CAM method achieved 53,94% success in treatment. It was determined that families with dissatisfaction and hopelessness from medical treatment had a positive attitude of 25 (20-39) with complementary and alternative medicine and were statistically significant(p=0.035). Conclusion: It was found that the use of CAM is high in families with asthma in their children and that they have a positive attitude towards CAM use. The increasing use of CAM shows the need for healthcare professionals to be informed about this issue

The hearing test performance rate was 89.1%, the hip USG rate was 53.4%, and the heel lance blood sampling test rate was 99.6%. Hearing test and hip USG screening rates decreased compared to previous years, while an increase was observed in heel blood sampling. The rate of patients undergoing examinations/controls in our neonatal clinic (n=560) to births (n=501) also decreased to 1.12 compared to previous years. Conclusion: A decrease was observed in hearing and hip USG screening in the first months of the COVID-19 pandemic. No decrease was observed in heel blood screening compared to the same period in previous years. Changes may be observed in the provision of basic health services in crises such as pandemics, and the requisite measures must be taken

Correlating Rate of Penetration with the Weight on Bit, Rotation per Minute, Flow Rate and Mud Weight of Rotary Drilling

In this study, the effect of some drilling parameters, rotation per minute, weight on bit, flow rate and mud weight on rate of penetration, were investigated in detail. As a result, the rate of penetration was found between 1,79m/h and 14,80m/h, which have a good statistical relationship with the rotation per minute, flow rate and mud weight. On the other hand, it was determined that there was no any relationship between rate of penetration and weight on bit
