Analysing existing models in the world and novelties in monitoring physical fitness in physical education classes, as well as similarities in economic and social parameters and conditions in which physical education classes in the Republic of Serbia and Bosnia and Herzegovina (BIH) are conducted, it was assumed that the model and the battery of tests from the Republic of Serbia could be adequate for application in BIH as well. Therefore the aim of this paper was to apply the suggested model and the battery of tests from the Republic of Serbia on a sample of one part of BIH (Una - Sana canton), as well as to compare the obtained data of Bosnian students with the data of the representative sample of students from Serbia. Also, the aim of the paper was to determine a percentage of Bosnian and Herzegovinian students who failed to accomplish acceptable results above the minimum level of 'physical fitness' set on the basis of Serbian Criterion-Referenced Standards. The sample of respondents was comprised of 843 students of eight primary schools that are representative for Una - Sana canton area, aged 11 to 15. For comparison of the obtained results and determination of distribution of frequency of Bosnian and Herzegovinian students with acceptable 'physical fitness' results we used data obtained on the representative sample of students from the Republic of Serbia the basis of which Serbian Criterion-Referenced Standards of physical development and motor abilities of primary school students in Serbia were set. Results of the study show that Serbian Criterion-Referenced Standards are acceptable for Bosnian and Herzegovinian primary school population of boys and girls for assessment of lower limb strength, shoulder girdle and abdominal muscles strength endurance, as well as flexibility, while the achieved results in tests for assessment of agility and general endurance need additional check within a national research in BIH.

Usprkos ubrzanu razvoju novih tehnologija i novih medija u društvu, ne postoji dovoljno jasna rasprava o pitanjima vezanim za medijsku pismenost. Novo medijsko okruženje u kojem su recipijenti sve aktivniji i u kojem posvećuju više vremena medijskim sadržajima, zahtijeva kvalitetan i odgovoran pristup medijskom obrazovanju, posebno djece i mladih. U području medijskoga obrazovanja ne postoji sustavan pristup podizanju razine medijske pismenosti kod djece. To je sustavan, interdisciplinaran i dugotrajan proces promjene. Medijska pismenost podrazumijeva posjedovanje određenih znanja i kreiranje kritičkoga pristupa. Razvijanje kritičkoga diskursa i stjecanje kompetencija ključan je cilj i interes medijskoga opismenjavanja. Ključne riječi: medijska pismenost, kompetencija, medijski odgoj, časopisi za djecu i mlade, kritički diskurs

Abstract: Iterative learning control (ILC) of continuous-time nonlinear plants with periodic sampled-data inputs is considered via an extremum seeking approach. ILC is performed without exploiting knowledge about any plant model, whereby the input signal is constructed recursively so that the corresponding plant output tracks a prescribed reference trajectory as closely as possible on a finite horizon. The ILC is formulated in terms of a non-model-based extremum seeking control problem, to which local optimisation methods such as gradient descent and Newton are applicable. Sufficient conditions on convergence to a neighbourhood of the reference trajectory are given.
