41. Teaching feints to handball beginners, preliminary resultsDavid Henigman, Katarina Ohnjec, 2021, other scientific articles Abstract: The aim of this preliminary research was the evaluation of a two-month program for improvement of the single forward feint to the left with passage to the right, and single forward feint to the right with passage to the left by “shifting” the opponent’s hand. Six-teen young male handball players aged 9.64 ± 0.87 years participated in this study. The program was implemented over two months, during which 18 training sessions (35%) were conducted for the improvement of feint skills, from 52 training sessions overall. An initial video recording was made at the beginning of the period, and a final one at the end. Videos were analyzed by three experts, using a grading list and detailed grad-ing criteria. The basic parameters of descriptive statistics were determined for both variables. The metric characteristics of the expert estimation contribution were ana-lyzed through measures of reliability (Cronbach’s α) and homogeneity (average item inter-correlation). The non-parametric (Wilcoxon t-test) method was used to analyze changes in the levels of feint performance at different times. The results indicate satis-factory reliability and homogeneity of the tests (α1=0.90; r1=0.80; α2 =0.86; r2=0.87). Through insight into the results, a significant difference was spotted between the initial and final states of both motor skills acquisitions (T1 = 114.5, p= 0.01; T2 =7.00; p= 0.01). The limiting factors of the study may be the sample size, as well as the absence of a control group and of a validated evaluation of the instrument

45. A glimpse of the lost Upper Triassic to Middle Jurassic architecture of the Dinaric Carbonate Platform margin and slopeBoštjan Rožič, Luka Gale, Primož Oprčkal, Astrid Švara, Tomislav Popit, Lara Kunst, Dragica Turnšek, Tea Kolar-Jurkovšek, Andrej Šmuc, Aljaž Iveković, Jan Udovč, David Gerčar, 2022, original scientific article Abstract: In the southernmost outcrops of the Slovenian Basin the Middle Jurassic coarse-grained limestone breccia (mega)beds are interstratified within a succession that is otherwise dominated by hemipelagites and distal turbidites. In this paper, these beds are described as the Ponikve Breccia Member of the Tolmin Formation. We provide descriptions of the studied sections with detailed geological maps and analysis of the breccia lithoclasts. From the latter, a non-outcropping margin of the Dinaric Carbonate Platform is reconstructed. In the Late Triassic the platform margin was characterized by a Dachstein-type marginal reef. After the end-Triassic extinction event, the platform architecture remained, but the reefs were replaced by sand shoals characterized by ooids. In the late Early Jurassic and/or early Middle Jurassic a slope area might have been dissected by normal faults and a step-like paleotopography was formed. In the Bajocian, during a period of major regional geodynamic perturbations, extensional or transtensional tectonic activity intensified and triggered the large-scale collapses of the Dinaric Carbonate Platform margin producing the limestone breccias described herein. This may in turn have caused a backstepping of the platform margin, as is evident from the occurrence of Late Jurassic marginal reefs that are installed directly above the Upper Triassic and Lower Jurassic inner platform successions.

47. Mid-Cretaceous calcarenite in stone products from the Roman colony of Emona, Regio X (modern Ljubljana, Slovenia)Rok Brajkovič, Bojan Djurić, David Gerčar, Blanka Cvetko Tešović, Boštjan Rožič, Luka Gale, 2022, original scientific article Abstract: Over the course of studying stone products from theRoman colony of Emona (Regio X), stratigraphicallyundefined calcarenite that was used to make simplesepulchral and architectural stone products wasdetected. The calcarenite used is late Aptian to earlyCenomanian in age. The corresponding facies werefound in the Lower Flyschoid Formation outcroppingnear the town of Medvode, within the local radius ofEmona. The Roman quarry was likely located in thisarea near the Sava River. According to the collecteddata, the quarry was in operation mainly in the 1stcentury.
