EXAMINATION OF ASSESSMENT AND EVALUATION ACTIVITIES OF SECONDARY SCHOOL 9TH AND 10TH GRADE PHYSICS TEXTBOOKS IN TERMS OF REVISED BLOOM TAXONOMY AND SCIENCE LITERACY COMPETENCE LEVELS: THE SAMPLE OF TURKEY

The purpose of this research is to examine assessment and evaluation activities of secondary school 9th and 10th grade physics textbooks in Turkey according to the revised Bloom Taxonomy and PISA science literacy competence levels. In this study document review, a qualitative research method was used. Within the scope of the study, assessment tools of 9th and 10th grade secondary school physics textbooks which are recommended by the Ministry of Education (Turkey) to be used in the 2017-2018 academic year were examined. As a result of the study, assessment and evaluation activities of 9th and 10th grade physics textbooks were found to meet generally 1, 2, 3 and 4 levels of PISA Science literacy competence levels. Moreover, when the same activities were examined according to the revised Bloom Taxonomy, the vast majority of the assessment activities are at the factual and conceptual level of the knowledge accumulation dimension, and at the applying and understanding sub-dimensions of the cognitive process dimension.  Article visualizations

Identification of chronic urticaria subtypes using machine learning algorithms

Chronic urticaria (CU) comes as chronic spontaneous urticaria (CSU) and chronic inducible urticaria (CIndU). Across its types and subtypes, CU is a heterogeneous disease that has different phenotypes with distinct clinical characteristics and different endotypes with distinct underlying pathophysiological mechanisms. It may be possible that subtypes of CU patients exhibit distinct phenotypic disease signatures that can point to differences in what drives their condition and in their response to treatments. Cluster analysis is a popular unsupervised machine learning (ML) method for discovering previously undetected data patterns. ML-based cluster analysis has been used in several diseases for the identification and characterization of patient subgroups. As of now, no study has attempted to identify CU subtypes with this method. Here, we performed a proof-of-concept study to test whether cluster analysis using ML algorithms can identify subgroups of CU patients based on clinical and routine laboratory characteristics.This project benefitted from the support (non-financial) of the GA2LEN network of urticaria centers of reference and excellence (UCARE, www.ga2len-ucare.com)

Stratejik stok yönetimi: Bir kamu hastanesi örneği

Businesses have to develop and implement effective stock policies to maximize profits by minimizing costs in today's market conditions. Since the stocks enterprises between 20% to 60% within total assets of manufacturings,  effective implementation of stock control and management policies, has great importance for the future of business.Businesses’ execution of it’s stock policies at the lowest cost depends on the forecasting amount of stock based on demand at least error, and minimum stock level determination and the appropriate time and amount of orders given to it. Thus, time and cost savings will be achieved by ensuring balance of continuity and speed in production of goods and services in the production process.By the rapid changes in consumer preferences, the variety of products, technologies and competitors are rapidly changing and increasing in rate. By increases in product variety, stock control and management is becoming even more difficult and complex.In recent years, effective and efficient resource use and management began to be kept in the foreground in public institutions as well as private sector. Public hospitals have been diverged from other business such as restaurant and hotel since it  is an inpatient treatment business.It’s obligation of keeping right supplies in right amount, in the right place at the right time and cost is more strict comparing other institutions.İşletmeler, günümüz piyasa koşullarında, maliyetleri minimize ederek karı maksimize edecek etkin stok politikalarını geliştirmeye ve uygulamaya mecburdur. Stoklar, üretim işletmelerinin toplam varlıklarının % 20 ile % 60’ı arasında bir yere sahip olduğundan etkin stok kontrol ve yönetim politikalarının uygulanması, işletmenin geleceği için büyük önem taşımaktadır. İşletmelerin stok politikasını en düşük maliyetle yürütebilmesi, talebe dayanan stok miktarının en az hatayla tahmini, asgari stok seviyesinin tespiti ve siparişlerin uygun zaman ve miktarda verilmesine bağlıdır. Böylece, ürün ve hizmet üretim sürecinde, üretim akış hızının denge ve sürekliliğini sağlanarak, zaman ve maliyet tasarrufu elde edilecektir.Tüketici tercihlerinin hızlı bir şekilde değişmesiyle birlikte piyasadaki ürün çeşitliliği, teknolojilerin ve rekabetçilerin değişim oranı da hızlı bir değişmekte ve artış göstermektedir. Ürün çeşitleri arttıkça stok kontrolü ve yönetimi daha da zorlaşmakta ve karmaşık hale gelmektedir.Son yıllarda kamu kurumlarında etkili ve verimli kaynak kullanımı ve yönetimi özel sektör kadar ön planda tutulmaya başlanmıştır. Kamu hastanelerinin yataklı tedavi kurumu olması nedeniyle restoran, otelcilik gibi yan uygulamaları ile diğerlerinden ayrılmaktadır. Doğru malzemeyi doğru miktarda, doğru zamanda ve uygun maliyetle ve doğru yerde bulundurma gerekliliği diğer kurumlara göre biraz daha fazladır

Evaluation of the Effects of Varicoceles and Fertility Status on Volumetry and Shear-wave Elastography

Aim: This study aims to compare the volumetry and shear-wave elastography findings in infertile and fertile patients and evaluate the effect of presence of varicoceles on the parameters. Materials-Methods: 40 infertile and 20 fertile patients (120 testes) (mean age 29,3±6,7) between January 2018-November 2018 were included in this prospective study. All patients underwent testicular B-mode and doppler ultrasonography (US) and shear-wave elastography (SWE). Patients were sub-grouped according to fertility status and presence or absence of varicoceles. Results: Testis stiffness was significantly higher in testes without varicoceles than those with varicoceles (p=0.021). It was also higher in fertile patients than infertile patients (p=0.015). Testes volumes were higher in fertile patients and patients with varicoceles (p=0.011 and p=0.028, respectively). Conclusion: SWE is a non-invasive, cheap and reproducible technique with promising results for diagnosis and follow-up in the evaluation of infertility

Comparison of the Analgesic Efficacy of Ultrasound-Guided Quadratus Lumborum Block and Ilioinguinal-Iliohypogastric Nerve Block in Paediatric Patients After Inguinal Hernia Surgery: A Prospective Randomized Controlled Trial

Objective:To compare the postoperative analgesic efficacy of quadratus lumborum block (QLB) and ilioinguinal-iliohypogastric nerve block (IIIHB) in paediatric patients who have undergone unilateral inguinal hernia surgery.Methods:This prospective randomized controlled study was designed in a single center and included 60 paediatric patients aged 2-7 years who had undergone inguinal hernia repair surgery and received an American Society of Anesthesiologists score of 1-2. Patients were randomized into two groups: those receiving ultrasound-guided QLB and those receiving IIIHB. The primary outcomes of the study were patients’ face, legs, activity, cry, and consolability (FLACC) scores at 1, 2, 6, 12, and 24 hours post-surgery.Results:The mean heart rate 15 and 30 minutes post-surgery in the QLB group was lower than that of the IIIHB group, and the difference at both times was statistically significant (P < 0.001). The mean FLACC score of the QLB group was lower than that of the IIIHB group at 6, 12, and 24 hours post-surgery, and the differences were statistically significant (P=0.004, P=0.006, and P < 0.001, respectively). Between the groups, there was no statistically significant difference in the number of patients who were administered rescue analgesics or oral ibuprofen, the time of first ibuprofen administration, or the frequency of complications (P=1.000, P=0.145, P=0.195, and P=1.000, respectively).Conclusion:Compared with IIIHB, QLB achieves superior postoperative analgesic effects in paediatric patients who have undergone inguinal hernia surgery, as evidenced by longer analgesic periods, lower pain scores, and lower analgesic consumption

Evaluation of Business Manager's Reverse Logistics Perspectives: Sample of Malatya Organized Industrial

The fact that technology has become an inseparable part of human life has led to an increase in the consumption and waste amount, a decrease in natural resources, and environmental pollution to reach important dimensions. Along with these improvements, protection of the environment and wastes have become a legal obligation in front of the enterprises, and as the society becomes conscious about the protection of the environment, it has become very important in terms of customer satisfaction. In the case of logistics, the concept of reverse logistics, which refers to the collection, storage and transport activities, which include the processes of recycling, reprocessing and destruction in general, became important. In this study, a descriptive research has been carried out on the business executives' evaluation of the reverse logistics perspective and their application to the reverse logistics. In this framework, first the theoretical framework for the concept of reverse logistics was established and the importance of reverse logistics for the country, society, environment and enterprises was emphasized and reverse logistics applications in our country were given place. In the application part of the study, face-to-face interviews were carried out with executives of 110 companies operating in the Malatya Organized Industrial Zone, and a survey was conducted. In the light of the obtained data, it is seen that the business executives see the level of reverse logistics as a social responsibility towards the environment and collectivity; how to look at the way in which reverse logistics can be used as an advertising tool and to give an environmental image to enterprises; the competitive advantage of reverse logistics, the contribution to customer satisfaction, and the degree of participation in the views that benefit the business economy are evaluated and analyzed whether the executives differ in terms of demographic characteristics and some basic characteristics of the enterprises

Comparison of the Shear Bond Strengths of Ceramic Brackets Using Either a Self-Etching Primer or the Conventional Method after Intracoronal Bleaching

Objective:To evaluate the initial shear bond strengths (SBSs) of ceramic brackets using either a self-etching primer (SEP) or the conventional method (CM) after intracoronal bleaching with sodium perborate and distilled water.Methods:Eighty human incisors were divided into four groups according to bleaching and bonding procedures: Group 1, bleaching was not applied and the brackets were bonded with a self-etching primer; Group 2, bleaching was not applied and the brackets were bonded with the conventional method; Group 3, intracoronal bleaching with sodium perborate was applied for three weeks and the brackets were bonded with a self-etching primer; and Group 4, intracoronal bleaching with sodium perborate was applied for three weeks and the brackets were bonded with the conventional method. A self-etching primer (Transbond Plus) was applied as recommended by the manufacturer. After SEP application, the ceramic brackets were bonded with a light-curing adhesive (Transbond XT). For the conventional method, the teeth were etched with 37% phosphoric acid. After etching, a thin uniform coat of primer (Transbond XT Primer) was applied and the ceramic brackets were bonded with a light-curing adhesive (Transbond XT). SBSs were measured after water storage for 30 days, after 1000 cycles of thermocycling between 5°C and 55°C. Bond failure location was determined with the Adhesive Remnant Index (ARI).Results:For the SEP method, there was no significant difference between SBS values of the bleaching and non-bleaching groups. Furthermore, for the conventional method, the SBS value of the non-bleaching group was not significantly different from that of the bleaching group. SBS values of the SEP method presented significant differences from those of the conventional method (p<0.001). SBS values of SEP application decreased with and without bleaching. The ARI scores did not show any significant difference among the groups (p=0.174).Conclusion:Intracoronal bleaching with sodium perborate and distilled water did not affect the SBS values of ceramic brackets

Is biopsy necessary? Role of DCE-MRI in BIRADS-3 lesions

PURPOSEWe aimed to evaluate BIRADS-3 breast lesions with dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) and compare with histopathology, and to investigate the effectiveness of breast MRI for follow-up and management.METHODSA total of 84 BIRADS-3 lesions reported by US or mammography and evaluated by DCE-MRI between September 2014 and October 2015 were included in this study. All patients underwent percutaneous or surgical biopsy for histopathologic diagnosis. Morphologic and kinematic features on MRI were compared with histopathologic results.RESULTSOf the 84 BIRADS-3 breast lesions, 9 (10.7%) had malignant features on DCE-MRI and all were verified with histopathologic results. DCE-MRI had 96.7% sensitivity, 72% specificity, 92% positive predictive value, and 82.5% negative predictive value. MRI and histopathology results were correlated for the diagnosis of malignant lesions. The sensitivity and negative predictive value of MRI for diagnosis of malignant lesions were both 100%.CONCLUSIONDifferentiation of benign versus malignant lesions was accomplished with 100% accuracy with DCE-MRI. We suggest that DCE-MRI should be an additional diagnostic tool and problem-solving modality for BIRADS-3 lesions, particularly in patients with relative risk factors

Okul Psikolojik Danışmanlarının Penceresinden Türk ve Suriyeli İlkokul Öğrencilerinin Gruplararası Empati Deneyimlerinin İncelenmesi

Araştırmanın genel amacı, aynı sınıflarda eğitim ve öğretim gören Türk ve Suriyeli ilkokul öğrencilerinin, birbirleri ile ne ölçüde empati kurabildiklerini, okul psikolojik danışmanlarının penceresinden incelemektir. Araştırma nitel bir çalışma olarak yapılandırılmıştır. Araştırmada nitel veri toplamak için standartlaştırılmış görüşme tekniği kullanılmıştır. Araştırma, 40 okul psikolojik danışmanıyla (8 erkek, 32 kadın) yüz yüze derinlemesine görüşmeler yapılarak gerçekleştirilmiştir. Türk ve Suriyeli ilkokul öğrencilerinin, diğer sosyal kimliğe sahip, sıkıntı çeken, haksızlığa uğrayan ve üzgün olan bir arkadaşlarını gördüklerinde hissettiklerinin ve gösterdikleri davranışların niteliğinin belirlenmesinde, birbirleriyle yaşadıkları arkadaşlık ilişkilerinin etkili olduğu saptanmıştır. Aynı zamanda, farklı sosyal kimliklere sahip kişiler arasında, ortak dil yeterliğinin, iletişimin, gruplararası temasın ve arkadaşlığın empati açısından belirleyici olduğu saptanmıştır. Üçüncü olarak en temel sonuç ise, Türk ve Suriyeli öğrenciler arasında arkadaşlık, sevgi, iletişim ve birbirlerine yönelik karşılıklı olumlu bir bakış açısı varsa, birbirlerinin yaşadıkları sıkıntılara, haksızlıklara ve üzüntüye karşı, daha duyarlı oldukları ve daha fazla yardım ve destek vermeye yöneldikleri saptanmıştır.
