There are currently no evaluation methods specific to ECAs in CVEs and traditional evaluation methods are limited in their applicability and consequently unlikely to address the full range of aspects now inherent in such systems. We argue that a combination of controlled experimentation, quasi-experiments, review-based evaluation and heuristic expert reviews is needed. To operationalise these t...

We apply and extend some well known and some recent tech niques from algebraic residue theory in order to relate to each other two major subjects of algebraic and numerical computing that is computa tions with structured matrices and solving a system of polynomial equa tions In the rst part of our paper we extend the Toeplitz and Hankel structures of matrices and some of their known properties ...

The magnetic field is a more complex and abstract physics subject than other subjects, causing students' low ability to solve problems. So there need for learning instruments overcome these problems, especially when online during the COVID-19 pandemic. Research creates implements an problem-based (OPBL) assisted by digital books with 3D animation improve problem-solving skills on subjects. aime...

conclusions ct is common in middle-aged working females. it affects supraspinatus tendon. it is associated with smoking. occupational risk factors are awkward positions and lifting weights. iontophoresis with 5% acetic acid and ultrasound is a safe, simple and inexpensive technique, capable to reduce pain and calcification, with a recommended degree of scientific evidence (2b). objectives to cl...

BACKGROUND The purpose of this paper is to review relationships of academic performance and some of its determinants to participation in school-based physical activities, including physical education (PE), free school physical activity (PA) and school sports. METHODS Linkages between academic achievement and involvement in PE, school PA and sport programmes have been examined, based on a syst...

This study investigates the question of whether short periods of medication-free research in early episode schizophrenia result in demonstrable long-term harm to human subjects. A meta-analysis of published quasi-experimental and random assignment studies that had a majority of first- or second-episode schizophrenia spectrum subjects, at least 1 initially unmedicated group, and a minimum of 1-y...

[Purpose] The present study investigated what kind of effect smart phone use has on dynamic postural balance. [Subjects] The study subjects were 30 healthy students in their 20's who were recruited from a University in Busan, Korea. [Methods] The present experiment was quasi-experimental research which measured the postural balance (Biodex) of subjects while they sent text messages via smart ph...

This study aims to determine the impact of problem-based learning on nursing student outcomes. The research method used is quasi-experimental by comparing two groups, namely group treated with and conventional learning. subjects were 7th semester students, totaling 68 students who divided into experiment control Analysis data in this outcomes experimental control. results analysis showed that o...
