The modern level of computer graphics programs (CGP) has long been able to solve most design, architecture, and lighting design problems. However, the use of CGP in teaching students is still underestimated. The existing traditional teaching methods cannot effectively teach the basics of lighting engineering and photometry to students. This is especially true for the concepts of illumination that are difficult to understand – luminance (radiance), color temperature. The article offers a method of teaching photometry based on the wide use of CGP. Within the methodology framework, 3D laboratories were developed. Students can study the basics of lighting engineering and optical effects, visually observe most lighting quantities, see their relationship, and interact with the surrounding space and objects. More than ten 3D training models on interior, architectural, and road lighting have been modeled. Within each model, students are given tasks for independent work. Checking the received material from students at several leading Russian universities allowed us to conclude on the methodology's effectiveness and outline many key aspects of its development.

Abstract This article reports on the development of usability engineering recommendations for next-generation integrated interoperable medical devices. A model-based hazard analysis method is used to reason about possible design anomalies in interoperability functions that could lead to use errors. Design recommendations are identified that can mitigate design problems. An example application of the method is presented based on an integrated medical system prototype for postoperative care. The AAMI/UL technical committee used the results of the described analysis to inform the creation of the Interoperability Usability Concepts, Annex J, which is included in the first edition of the new ANSI/AAMI/UL 2800-1:2019 standard on medical device interoperability. The presented work is valuable to experts developing future revisions of the interoperability standard, as it documents key aspects of the analysis method used to create part of the standard. The contribution is also valuable to manufacturers, as it demonstrates how to perform a model-based analysis of use-related aspects of a medical system at the early stages of development, when a concrete implementation of the system is not yet available.

The acquisition of reading comprehension abilities and written expression is one of the key factors among learning processes in which students show many difficulties. For this reason, it is necessary to implement effective intervention strategies from early school years. The program EPI.com is aimed at improving lexical, semantic, and syntactic processes related to the reading process. This work aims to analyze the efficiency of EPI.com in years 1&2 of Primary Education. Participants in the research were 62 students (ages 6–8), who were assigned to an Experimental Group (EG; 38 students receiving the EPI.com intervention) and a Control Group (CG; 24 following traditional teaching and learning methods). The Illinois Test of Psycholinguistic Abilities and the Peabody test were applied before and after the intervention was carried out. Results showed that the strategy was effective in EG in improving the psycholinguistic aspects measured by the ITPA, with better results in the variables related to syntactic and lexical processing. Taking the results into account, it was concluded that EPI.com allows students to improve the abilities relating to reading skills. Also, the results highlight the need to incorporate interventions aimed at favoring maturation in some key aspects at early ages.

This work is devoted to the creation of a laboratory workshop (virtual) for open online courses based on programs of three-dimensional computer graphics and multimedia. The issues of using SolidWorks, Autodesk® 3DS MAX software in distance learning are discussed. The software was used to prepare training materials for the courses course "Machines and mechanisms theory", "Computer Graphics" and "Engineering and Computer Graphics". Using the software product SolidWorks, Autodesk® 3DS MAX has significantly increased the visibility of the course and develop tools for organizing the independent work of students in an interactive mode.

Teachers in numerous countries worldwide often confront education reforms in their career, in which, collaborating is considered a feasible approach to changing teachers’ traditional teaching philosophy. This study aims to examine Taiwanese teachers’ experiences of collaborating in school teaching teams. We invited six teachers from different schools for an interview. Afterward, we conducted two sessions of focus-group interviews with 18 participants from various roles in teaching teams as well as various geographical areas. The findings show that information exchanges of education works, uncoordinated processes of collaboration, and discussions not involving pedagogical knowledge are the general experiences on participating in the teaching teams. Certain barriers to teacher collaborations are from inadequate focuses during team discussions and a lack of curriculum leadership. Through experience-sharing, the participants considered that a focus on student learning during discussions and examples of practices for curriculum leadership were the key aspects for successful experiences in teacher collaborations.

Abstract Introduction: Microsurgery training is a key step for the young neurosurgeons. Both in vascular and peripheral nerve pathology, microsurgical techniques are useful tools for the proper treatment. Many training models have been described, including ex vivo (chicken wings) and in vivo (rat, rabbit) ones. Complex microsurgery training include termino-terminal vessel anastomosis and nerve repair. The aim of this study was to describe a reproducible complex microsurgery training model in rats. Materials and methods: The experimental animals were Brown Norway male rats between 10-16 weeks (average 13) and weighing between 250-400g (average 320g). We performed n=10 rat hind limb replantations. The surgical steps and preoperative management are carefully described. We evaluated the vascular patency by clinical assessment-color, temperature, capillary refill. The rats were daily inspected for any signs of infections. The nerve regeneration was assessed by foot print method. Results: There were no case of vascular compromise or autophagia. All rats had long term survival (>90 days). The nerve regeneration was clinically completed at 6 months postoperative. The mean operative time was 183 minutes, and ischemia time was 25 minutes.

Modern students are digital natives: from an early age, they are used the Internet, social networks and mobile systems. Due to the specific brain structure of Generation Z students, the use of traditional teaching tools makes the learning process not effective. Also, an insufficient number of lecture hours in curricula requires from students more independent work. This article presents the experience of creating interactive teaching materials designed to study and master the skills of graphical engineering subjects. Educators of technical universities from five countries took part in the development of the material. These interactive teaching tools are created with the aim of improving the quality of engineering education, the rapid and effective presentation of educational material, which will contribute to the understanding of difficult topics.

The article is dedicated to Kiev ex-libris school role (EL) in modern Ukrainian printmaking. The loss process by a bookplate of utilitarian, applied functions and its transformation into an independent work of art, collectors' object of interest with an appreciated art value is described. The ex-libris schools formed in the first quarter of the 21st century are emphasized, the main trends of the bookplate development predominant centers are defined (Kiev, Lvov, Odessa, Luhansk). Printmaking techniques, typical for a particular ex-libris school, are marked. Kiev bookplate school, as one of the leading centers for the classical xylography traditions preservation, is underlined. The most significant masters, working in these techniques, are presented, the technological process evolution is indicated and its main reasons are emphasized. The problem of opposition between the old and new in the art of printmaking is touched upon by example of classical techniques and gathering momentum computer graphics (CGA) coexistence.
