Certain research on the development of motor skills of children with hearing impairment shows that their abilities are not age-appropriate, although they have the same basis for development as hearing children. Education of children with hearing impairments is predominantly focused on hearing and speech rehabilitation, while activities related to music and sports are mostly neglected. The aim of this study was to examine the effects of musical-rhythmic stimulation on the development of selected motor skills of children with hearing impairment aged six to fifteen. For this purpose, a special music and dance program of workshops for 26 children with hearing impairments (12 boys and 14 girls) was created for the period of four and a half months. At the beginning of the program implementation, the initial measurement of body coordination and speed of movement was performed, and the final measurement through five standardized tests at the end. The paired samples t-test was used to analyze the effects of applied musical-rhythmic and dance stimulations. The results of the research indicated certain statistically significant differences in the ability to coordinate the body and speed of movement, i.e. that the program of music and dance workshops has a positive effect on the development of selected motor skills in children with hearing impairment.

Određena istraživanja o razvoju motoričkih sposobnosti djece s oštećenjem sluha pokazuju da njihove sposobnosti nisu u skladu s dobi iako imaju iste osnove za razvoj kao i čujuća djeca. Edukacija djece s oštećenjem sluha dominantno je usmjerena na rehabilitaciju sluha i govora, a aktivnosti vezane za glazbu i sport uglavnom su zanemarene. Cilj ovog istraživanja bio je ispitati učinke glazbeno-ritmičkih stimulacija na razvoj odabranih motoričkih sposobnosti djece s oštećenjem sluha u dobi od šest do petnaest godina. Zbog toga je kreiran poseban glazbeno-plesni program radionica za 26 djece s oštećenjem sluha (12 dječaka i 14 djevojčica) u trajanju od četiri i pol mjeseca. Na početku realizacije programa provedeno je inicijalno mjerenje koordinacije tijela i brzine pokreta te po završetku finalno mjerenje kroz pet standardiziranih testova. Za analizu efekata primijenjenih glazbeno-ritmičkih i plesnih stimulacija korišten je t-test za završne uzorke (paired samples test). Rezultati su istraživanja ukazali na određene statistički značajne razlike u sposobnostima koordinacije tijela i brzine pokreta, odnosno da program glazbeno-plesnih radionica ima pozitivan učinak na razvoj odabranih motoričkih sposobnosti kod djece s oštećenjem sluha.

Properly determined fuel consumption enables the calculation of the amount of carbon dioxide emitted and preventive measures, as well as the choice of its reduction strategy. Data collection took six months, then the data were analyzed, and thus the results were given for all dump trucks by months.

Europe, with all its common sights, has an enviable wealth of history and cultural heritage. With its many monuments, sites, traditions, history, art, and culture, it has always attracted curious views and tells centuries-old stories to many tourists and visitors. At the heart of Europe, Bosnia and Herzegovina (BiH), founded in the 11th century, with its picturesque past, has always been at the crossroads of faith and civilizations. The key audience of tourism in BiH are nature lovers, adventurers and young and digital nomads, who represent great potential for the development of this sector given their nature of work, to be able to work from any location, and during the COVID-19 period. Furthermore, the importance of the diaspora for the development of tourism in BiH goes beyond tourist visits and helps BiH on its path to digital transformation. Digital tourism refers to how we use digital tools to organize, manage and even enjoy the travel experience. It uses all of the tools of digital transformation to change how we travel and experience different sites. Through digitalization, we want to reach every individual who passes through this country and further attract lovers of European history and culture, offer them a different, more creative, and innovative approach to learning about the cultural and historical treasures it hides. The goal of digital tourism is to raise awareness of the importance of cultural heritage, provide new opportunities for visitors and bring new knowledge. Therefore, this paper provides an overview of the possibilities of digital representations of the medieval historical period of BiH through identified pillars of digital reconstruction, and ways to connect the movable cultural heritage residing in the museums with real sites in an attempt to contribute to its promotion through digital tourism. © 2022 Copyright for this paper by its authors.

The paper points out the leading role of the HR department in crisis situations, with special emphasis on the crisis caused by the COVID-19 pandemic, which affected the whole world in early 2020. Regardless of the intensity and form in which they occur, crises threaten the functioning and survival of organizations. The HR department is an important factor in the successful functioning of organizations and, in a period of crisis, this department takes a leading role in the process of crisis management and subsequent recovery. During COVID-19 pandemic, the HR department of every organization had to confront new challenges in order to protect the health of employees, while ensuring the normal functioning of organizations. In order to find out how this department dealt with crisis that occurred, empirical research with a specially designed questionnaire was conducted and filled in by 108 respondents from Serbia, Bosnia and Herzegovina, and Croatia in 2020. The research results showed that HR department has taken a leading role in preserving the health and safety of employees, as well as in the process of adapting organizations to function in crisis conditions. According to results, the key activities carried out by the HR department in organizations are work from home (wherever the nature of the work allowed), flexible working hours, reorganization of the working space to achieve the required physical distance between employees, improved hygiene measures, etc. In addition, the research results showed that, during the global COVID-19 pandemic, the HR departments took an active role in providing psychological assistance to employees to adapt to new conditions and ways of working.

Selective separation and removal of a metal species from complex matrices of other species is of critical importance in separation sciences and especially in industrial processes. The selectivity and efficiency of Pb(II) ion removal from an aqueous solution in the presence of Ni(II), Zn(II), Co(II), Cu(II), and Cd(II) ions as competing ions in a multi-component aqueous source phase through bulk liquid membrane system were investigated. The influence of the palmitic and oleic acid as supporting surfactants in the membrane phase on the removal of Pb(II) ions was also analyzed. Dicyclohexano-18-crown-6 dissolved in chloroform, proved to be a selective and efficient carrier for Pb(II) ions. In the optimized procedure, 3 hours of equilibrium time was required to achieve the maximum removal efficiency. It was found, that removal of Pb(II) ions was achieved without significant reduction in the efficiency compared to the liquid membrane transport of a single-component system. None of these cations interfered with Pb(II) removal. The presence of the oleic and palmitic acid in the membrane phase increase the content of Pb(II) removed to the receiving phase. In optimal transport conditions, more than 97% efficiencies for the removal of Pb(II) were obtained for a system supported by oleic acid. The excellent efficiency and high degree of selectivity for the Pb(II) ion removal by the proposed BLM system, reveals its potential application for the selective removal, concentration, and purification of lead ions from its different mixtures.

: The objective of this study was to test the inhibitory effect of five newly synthesized arylmethylene-bis(3-hydroxy- 5,5 -dimethylcyclohex-2-en-1- one) derivatives. The structural characterization and stereochemistry of synthesized compounds were deduced from analyses of experimental FT- IR, 1 H, 13 C NMR spectra and theoretical methodology of DFT study based on the global chemical reactivity indices calculated using the 6- 31G** level of theory. the stability of the newly synthesized compounds, the reactivity descriptors obtained at B3LYP level ( E gap , dipole moment, μ , η , ω ) were computed. The docking study and the selected quantum chemical descriptors computed for compounds 1 −5 exhibit a good agreement. The strongest inhibitors showed 25 to 30 % inhi bition of tyrosinase activity. Results were supported by docking studies of the binding of the strongest inhibitors to the enzyme. The results suggest that tetraketones of this type, due to their tyrosinas e inhibitory effect, represent potential agents in the treatment of various types of melanomas and skin hyperpigmentation. 189.42 3´), 190.75 - C -1´).
