Eye and cat scratch disease: A case series

2016

Resume Introduction La maladie des griffes du chat est une affection polymorphe, pouvant se manifester par des atteintes ophtalmologiques isolees. Nous rapportons les observations cliniques de sept cas, ayant presente une atteinte ophtalmologique posterieure de la maladie des griffes du chat. Observations Notre population comprenait sept patients, dont cinq femmes, d’âge median de 52 ans, avec une atteinte unilaterale dans trois cas. Une neuroretinite stellaire de Leber etait retrouvee chez six patients, un syndrome incomplet dans deux cas (soit un œdeme papillaire isole, soit un œdeme maculaire trainant) et associe a des foyers chorioretiniens dans un cas. Des foyers retiniens isoles ont e…

Mathematical and Coding Lessons Based on Creative Origami Activities

2019

AbstractThis paper considers how creativity and creative activities can be encouraged in regular mathematical classes by combining different teaching approaches and academic disciplines. We combined origami and paper folding with fractals and their mathematical properties as well as with coding in Scratch in order to facilitate learning mathematics and computer science. We conducted a case study experiment in a Serbian school with 15 high school students and applied different strategies for learning profound mathematical and coding concepts such as fractals dimension and recursion. The goal of the study was to employ creative activities and examine students’ activities during this process i…

Ohjelmoinnillinen ajattelu laaja-alaisessa oppimisessa

Tietokonevallankumous ja ohjelmoinnillinen ajattelu peruskoulussa : havaintoja mikro- ja makrotasoilta

2022

Väitöskirjassa tutkitaan ”ohjelmoinnilliseksi ajatteluksi” lanseeratun tieto- ja taitokokonaisuuden oppimista, opettamista ja arviointia perusopetuksessa. Tämän erityisesti ohjelmoinnin kautta opittavan osaamiskokonaisuuden tuloa koulumaailmaan on kiihdyttänyt ennen kaikkea tietokoneiden ja tietokoneohjelmien kasvanut läsnäolo eri elämänalueilla. Ohjelmoinnillinen ajattelu on kuitenkin ollut jokseenkin hajanaisesti ymmärretty aihepiiri kasvatusalalla, mistä kielii muun muassa sen varsin suppea jalansija peruskoulumme opetussuunnitelmassa. Väitöstutkimuksessa selkeytettiinkin ohjelmoinnillisen ajattelun kasvatustavoitteita määrittelemällä aihealueen opetuksen perusprinsiipit. Tutkimuksen kes…

Microscratch testing method for systematic evaluation of the adhesion of atomic layer deposited thin films on silicon

2016

The scratch test method is widely used for adhesion evaluation of thin films and coatings. Usual critical load criteria designed for scratch testing of coatings were not applicable to thin atomic layer deposition (ALD) films on silicon wafers. Thus, the bases for critical load evaluation were established and the critical loads suitable for ALD coating adhesion evaluation on silicon wafers were determined in this paper as LCSi1, LCSi2, LCALD1, and LCALD2, representing the failure points of the silicon substrate and the coating delamination points of the ALD coating. The adhesion performance of the ALD Al2O3, TiO2, TiN, and TaCN+Ru coatings with a thickness range between 20 and 600 nm and dep…

A Study on the Assessment of Introductory Computational Thinking via Scratch Programming in Primary Schools

2018

Computational thinking (CT), a transversal intellectual foundation integral to computer science, is making its way into compulsory comprehensive education worldwide. Students are expected to attain skills and knowledge in such interdisciplinary CT principles as Algorithmic thinking, Data representation, and Debugging. Problem-solving by designing and manipulating interactive media with Scratch, a graphical programming tool, is popular especially at the primary school level. However, there has been confusion regarding how introductory CT can be operationalized for educational practice. Teachers and students need research-based knowledge for setting appropriate learning goals in addition to i…
