Abstract: Analyzing asymmetry from biomechanical parameters of the lower extremities has become a standard practice for accurate assessment of athletic performance, injury prevention, and rehabilitation. The aims of this study were (1) to determine differences between explosive strength and asymmetry of the lower extremities using kinetic parameters of the CMJ jump test in young female athletics, and (2) to investigate correlation between speed and asymmetry, as speed and kinetic parameters. The two groups of nine female sprinters (mean ± SD; G1-age 15.6 ± 1.34 years, height 170.1 ± 0.57 cm, body mass 62.54 ± 7.73 kg, and BMI 21.6 ± 2.05; G2-age 16.2 ± 1.3 years, height 168.4 ± 0.61 cm, body mass 57.69 ± 3.12 kg, and BMI 20.37 ± 1.38) performed the CMJ test without using an arm swing, as well as a 100 m test. Two tensiometric platforms were used for the kinetic parameters and asymmetry. Asymmetry was calculated by an AI equation, and the values of the takeoff velocities and jump height parameters were obtained by integral formula and the trapezoidal rule of impulse-momentum methods. The results show differences in four kinetic parameters: height (G1- 26.82 ± 3.56 cm, vs. G2- 17.45 ± 2.01 cm), concentric impulse, (G1- 96.05 ± 16.95 N·s, vs. G2- 68.41 ± 4.77 N·s), takeoff velocity, (G1- 2.29 ± 0.14 m/s, vs. 1.83 ± 0.12 m/s), and concentric velocity, m/s (G1- 1.5 ± 0.175 m/s, vs. 1.17 ± 0.122 m/s), as well as a negative strong and very strong correlation between asymmetry and kinetic parameters for three parameters: Peak Force (G1- r = −0.878, and all subjects r = −0.633), Eccentric Impulse of left leg (G1- r = −0.865) and Concentric Impulse of right leg (G2- r = −0.878), (p <.05). The younger sprinters did not show the principle of muscle activation in the form of a longer preparatory phase of contact time, eccentric and concentric phase, as well as a force impulse that is optimal. There was no correlation between asymmetry and sprint performance.

Abstract: Important keys to effective communication are language competences, which can be supported by using digital language resources. These usually assist the acquisition of a second language, despite their potential for improving one’s native language. Our study was, thus, aimed at raising awareness about the possibilities of improving the native language of an adult population by using digital language resources for the Slovenian language. We conducted workshops, a survey and, partly, semi-structured interviews with 124 participants. We examined whether the perceived usefulness and ease of using digital language resources depends on age, education, self-assessed language proficiency, and experience with language training. The analysis revealed that self-initiative use of analogue language resources is related positively to using digital ones for seeking information, improving language use, as well as for study or work. Moreover, self-assessed proficiency in language was found to affect the perceived ease of using digital language resources. These findings may help language professionals support developing language skills by using digital language resources and preserving language in an adult population.

Abstract: V magistrskem delu predstavljena raziskava razkriva, kakšno je trenutno stanje filmske kritike v Sloveniji z več različnih aspektov. S pomočjo intervjujev, ki smo jih izvedli s petimi različnimi filmskimi kritiki, ugotavljamo, da je filmska kritika v Sloveniji kvalitetna, a ima svoje ogromne omejitve ter izzive. Filmska kritika je pomembna za filmsko kulturo v Sloveniji, zaradi česar je potrebno javnost čim bolj ozaveščati o njej. V okviru predlaganega dela smo poskusili tudi pri ostalih kritikih ugotoviti, ali se pojavljajo tovrstne težave ter kako bi lahko delovanje izboljšali.
Keywords: filmska kritika v Sloveniji, filmska industrija v Sloveniji, filmsko novinarstvo, digitalizacija medijske industrije, digitalna doba filmske kritike.

Abstract: Diplomsko delo se osredotoča na moralne dileme, s katerimi se soočajo mediji pri poročanju. Obravnava, kako se ti v času digitalizacije soočajo z moralnimi dilemami ter kako to vpliva na širjenje neresnic in manipulacijo informacij, ki oblikujejo javno mnenje. Cilj dela je raziskati, kako se mediji soočajo z dilemami ter kakšne posledice prinaša nemoralno delovanje v medijih. Z analizo konkretnih primerov medijskih poročanj delo proučuje etične vidike ter skuša oblikovati smernice za odgovornejše in bolj etično sprejemljivo medijsko poročanje. Delo ugotavlja, da lahko zaradi dilem v medijih pride do manipulacij in širjenja neresnic, kar vpliva na zaznavanje javnosti.
Keywords: moralne dileme, resnica, medijska etika, novinarstvo

Abstract: Diplomsko delo preučuje finančne modele in upravljanje javnih RTV servisov v evropskem prostoru. Namen naloge je analizirati finančno in upravljavsko stanje petih evropskih javnih RTV servisov s pomočjo primerjave letnih poročil, pregleda zakonodaje in literature. Analizirali smo razvojne trende, spremembe v financiranju in uporavljanju ter ključne izzive, s katerimi se soočajo ti servisi. Identificirali smo, da so kljub stabilnim prihodkom servisi soočeni s finančnimi težavami, potrebo po digitalni transformaciji in iskanju novih virov financiranja. Ugotovitve kažejo na potrebo po nadaljnjem raziskovanju, vključujoč več podatkov in poglobljeno analizo vpliva digitalne transformacije.
Keywords: javni RTV servis, finančni modeli, upravljanje.
