Physically-based simulation of hair strips in real-time

In this paper, we present our implementation of physically-based simulation of hair strips. We used a mass-spring model followed by a hybrid approach where particle systems and the method of clustering of hair strands are employed. All the forces related to springs are implemented: gravity, repulsions from collisions (head and ground), absorption (ground only), frictions (ground and air), internal spring frictions. Real-time performance is achieved for physically-based simulation of hair strips and promising results in terms of the realistic hair behavior and hair rendering are obtained.

A New Neolithic Settlement in the Upper Tigris Basin in the Light of its Knapped Stone Assemblages: Boncuklu Tarla

Neolithic Age sites in the Upper Tigris Basin have significantly increased in number over the past few years, not least because of rescue excavations related to the Ilısu Dam Project undertaken over the last decade. The resultant data has produced significant new information about this hitherto little documented period in the region. Boncuklu Tarla was discovered in 2008 during a field survey, with excavations beginning in 2012. This paper details the knapped stone assemblage from a single season of excavation, material that shed important light on the Pre- Pottery Neolithic B of the Upper Tigris Basin, adding to the information we previously knew from the important site of Çayönü

Firing deformation in large size porcelain tiles. Effect of compositional and process variables

Ponencia presentada en el XV Congreso Mundial de la Calidad Del Azulejo y del Pavimento Cerámico (QUALICER 18), celebrado en Castellón (Spain) los días 12 y 13 de febrero de 2018.The manufacture of porcelain stoneware has undergone a spectacular growth in the last years, as a result of the good technical and functional performance associated to the impervious feature of the sintered product, together with the great technological advance that the ceramic tile manufacturing sector is experiencing [1]. To such an extent, that today, porcelain stoneware is the most demanded product for use in flooring surfaces, but at the same time, it is becoming important to incorporate in other applications such as ventilated facades

RELIABILITY ANALYSIS FOR EVALUATING SKILLS IN PEDIATRIC BASIC LIFE SUPPORT PERFORMANCE

Amaç: Tıp Fakültesi öğrencilerinin mesleksel becerilerinin değerlendirilmesindekullanılan ölçme değerlendirme yöntemlerinin geçerli ve güvenilir olması önemlidir.DEÜ Tıp Fakültesi Mesleksel Beceriler Komitesi tarafından hazırlanmış olan 25puanlı Pediyatrik Temel Yaşam Desteği (Pediyatrik TYD) ölçeği (25 PÖ) ve 35puanlı 5\'li Likert tipi ölçek (35 PLÖ) kullanılarak gerçekleştirilen bu çalışmada,öğrencilerin Pediyatrik TYD uygulama becerilerinin değerlendirilmesinde kullanılanölçekler ve değerlendiriciler arası tutarlılığın ve güvenilirliğin araştırılması amaçlanmıştır.Gereç ve yöntem: Tıp Fakültesi Dönem II öğrencileri (n: 140) I. yarı yıl sonunda ikigrup halinde Pediyatrik TYD beceri sınavına alındı. Her bir grup, biri Anesteziyolojive Reanimasyon Uzmanı, diğeri Mesleksel Beceriler Laboratuvarı Eğiticisi olmaküzere iki kişi tarafından değerlendirildi. Puanlama her bir öğrenci için 25 PÖ ve 35PLÖ ile ayrı ayrı yapıldı. Uygulamanın ardından öğrencilerden de aynı ölçeklere görekendilerine puan vermeleri istendi. Ölçekler ve uzman, eğitici, öğrenci puanlarıarasındaki korelasyon istatistiksel yöntemlerle değerlendirildi.Bulgular: 25 PÖ ve 35 PLÖ iç tutarlılığı sırası ile (Cronbach α) 0,734 ve 0,793bulundu. İki ölçeğin toplam skorları yüksek derecede (r:0,935) tutarlıydı.Değerlendiriciler arası tutarlılık 25 PÖ için, I. grupta r: 0,770, II. grupta r: 0,763; 35PLÖ için I. grupta r: 0,748, II. grupta r: 0,763 bulundu.Sonuç: 25 PÖ ve 35 PLÖ değerlendirme ölçekleri, mezuniyet öncesi eğitimdePediyatrik TYD uygulama becerisini değerlendirmede kullanılabilecek güvenilirölçeklerdir.Objective: The reliability and validity of the assessment methods used in assessmentof Professional Skills of medical students is important. In this study using the 25points scale (25 PS) for evaluating Pediatric Basic Life Support prepared by DEUMedical School Professional Skills Committee and the 35 points 5 point Likert typescale (35 PLS), it was aimed to investigate reliability and consistency between examiners and the scales used inevaluation of performance ofmedical students in Pediatric BasicLife Support (Pediatric BLS). Material and method: Year II medical students (n: 140) participated in thePediatric BLS skills examination in two groups at the end of the first term. ThePediatric BLS skills of each group were assessed by two examiners, oneAnesthesiology and Reanimation specialist and by a trainer from the ProfessionalSkills Laboratory. For each student scoring was performed using both the 25 PS and35 PLS. Following completetion of the assessment, students were asked to scorethemselves using the same scales. Correlation between the scales and the specialist,trainer and the student scores were evaluated using statistical methods.Results: The internal consistency of 25 PS and 35 PLS were (Cronbach α) 0.734 and0.793 respectively. The total scores for the two scales were correlated significantly(r:0.935). The consistency among the examiners were r: 0.770 in the first group andr: 0.763 in the second group for 25 PS; and r: 0.748 in the first group, and r: 0.763in the second group for 35 PLS.Conclusion: 25 PS and 35 PLS evaluation scales are considered to be reliablestudent evaluation scales to be used in assessment of Pediatric BLS skills inundergraduate medical education
