Since the COVID-19 pandemic made online classes a necessity throughout the
world, Serbia included, the music education system has gone through an
extensive transformation, and the teachers faced a ...number of difficulties
and challenges in their work. With this paper, we wanted to provide a clear
insight into the teaching practices that were established after the pandemic
was declared. The goal was to identify the obstacles that appeared in online
classes for musical instruments, but also the advantages that, according to
the teachers, may be integrated into traditional classes once the pandemic
is over. The research was based on a sample of 220 teachers of elementary
music schools, combining a qualitative and quantitative analysis of the
obtained data. The results have shown that teachers, younger ones in
particular, overcome the obstacles of online teaching without major
difficulties. As to the particular difficulties they encountered, the
teachers most often mentioned those of a technical nature, and the inability
to properly work on the techniques of playing an instrument due to the lack
of a direct contact with the students. Almost all of the teachers feel that
the students cannot improve their skills through online classes as
effectively as in a regular class. However, in their future work, the
teachers would continue to make audio and video recordings of themselves and
their students playing, and practice online teaching when the students are
sick or otherwise unable to attend regular classes. The pedagogical
implications of this research are that it is necessary to implement
technological solutions that would support all aspects of instrument
instruction, but also to intensify technical support for teachers,
particularly older ones, regarding competences needed for online classes.
This paper presents research that aimed to determine how teachers employed in Croatian and Serbian music schools coped with distance learning during the COVID-19 pandemic. The random sample was ...represented by 589 teachers working in music schools, of which 369 were from Croatia and 220 were from Serbia. The results showed that teachers from both countries successfully dealt with the implementation of distance music education. The results also showed that the youngest teachers are the most confident in their abilities and knowledge for using electronic devices in distance learning. Teachers believe that students cannot progress in distance learning as much as they can in traditional teaching. Technological difficulties (poor internet, poor audio and visual transmission) are the most common problem faced by teachers in distance learning. Also, most teachers stated that they would keep some of the distance learning elements in their future work. The results of this research can serve as a guide in achieving the necessary changes in music teaching which, with more extensive integration of information and communication technologies (ICT) in the teaching process, would provide a better and more efficient transition of teachers and students to a virtual environment.

Ovaj rad predstavlja rezultate empirijskog istraživanja provedenog radi ispitivanja mišljenja učitelja vokalno-instrumentalne i teorijske nastave pri hrvatskim i srpskim glazbenim školama o učenju na ...daljinu. Istraživanje je provedeno tijekom svibnja 2020., u vrijeme kad su sve glazbene škole zbog pandemije COVID-19 u potpunosti prešle na sustav učenja na daljinu. Rezultati pokazuju da su se učitelji, usprkos brojnim problemima, osobito lošim internetskim vezama i lošom kvalitetom zvuka dobivenim elektroničkim uređajima, uspješno nosili s realizacijom nastave glazbe na daljinu. Pronađene su statistički značajne razlike u odgovorima nastavnika o učenju na daljinu s obzirom na vrstu nastave koju vode, pa su učitelji koji izvode instrumentalnu i vokalnu nastavu bili bolji u izvođenju učenja na daljinu u odnosu na one koji vode teorijsku nastavu. Usprkos vjerovanju nastavnika da je prijenos potpunog znanja nemoguć putem tehnologije, većina njih otvorena je za mogućnost smislene primjene IKT-a. Stoga se intenzivira pitanje profesionalnog usavršavanja i kontinuirane podrške učiteljima od strane nadležnih institucija Hrvatske i Srbije.
This paper presents the results of empirical research conducted to examine the opinion of teachers of vocal, instrumental, and theoretical teaching at Croatian and Serbian music schools on distance learning. The survey was conducted during May 2020, at a time when all music schools have completely switched to a distance learning system due to the COVID-19 pandemic. The results showed that teachers, despite numerous problems, especially poor internet connections and poor sound quality obtained by electronic devices, have successfully coped with the realization of distance music teaching. Statistically significant differences were found in teachers’ responses about distance learning regarding the type of classes led by teachers, so teachers who lead instrumental and vocal classes are better at performing distance learning compared to those who lead theoretical classes. Despite the belief of teachers that the transfer of complete knowledge is impossible through technology, most of them are open to the possibility of meaningful application of ICT. Therefore, the issue of professional development and continuous support to teachers by the competent institutions of Croatia and Serbia is intensifying.
In this study, a cost-effective sandwich ELISA test, based on polyclonal antibodies, for routine quantification SARS-CoV-2 nucleocapsid (N) protein was developed. The recombinant N protein was ...produced and used for the production of mice and rabbit antisera. Polyclonal N protein-specific antibodies served as capture and detection antibodies. The prototype ELISA has LOD 0.93 ng/mL and LOQ 5.3 ng/mL, with a linear range of 1.52-48.83 ng/mL. N protein heat pretreatment (56 °C, 1 h) decreased, while pretreatment with 1% Triton X-100 increased analytical ELISA sensitivity. The diagnostic specificity of ELISA was 100% (95% CI, 91.19-100.00%) and sensitivity was 52.94% (95% CI, 35.13-70.22%) compared to rtRT-PCR (Ct < 40). Profoundly higher sensitivity was obtained using patient samples mostly containing Wuhan-similar variants (Wuhan, alpha, and delta), 62.50% (95% CI, 40.59 to 81.20%), in comparison to samples mostly containing Wuhan-distant variants (Omicron) 30.00% (6.67-65.25%). The developed product has relatively high diagnostic sensitivity in relation to its analytical sensitivity due to the usage of polyclonal antibodies from two species, providing a wide repertoire of antibodies against multiple N protein epitopes. Moreover, the fast, simple, and inexpensive production of polyclonal antibodies, as the most expensive assay components, would result in affordable antigen tests.
