The purpose of this study was to investigate whether 7th and 8th grade gifted students' academic achievements in mathematics and physics differ in terms of age, gender, grade level and number of siblings. Survey research method was used and 339 students, attending Science and Art Centers from 27 province, formed the sample of study. Mathematics and physics achievement tests and a demographic survey scale were developed by the researchers to measure and collect information about students' achievements and demographics properties. The validity and reliability evidences were established. The results denoted that there was a significant difference between students' collective dependent variables of mathematics and physics in terms of grade level and gender at the .05 significance level. But no significant differences were found for the gender and the number of sibling. Moreover 8th grade students' achievement in both physics and mathematics were significantly greater than those of 7th grade students. The results also denoted that students' mathematics and physics achievements differ significantly in terms of age. Although mathematics achievement increases with respect to age level, the same relation was not detected for the physics achievement. It is thought that the results of current study would contribute to the literature for the gifted students who comprised approximately 2% of the society.

SummaryAlthough factor V Leiden (FVL) is a major determinant of thrombotic risk, the reason why less than 10% of carriers eventually develop venous thromboembolic (VTE) events is unknown. Recent observations suggest that circulating levels of microparticles (MP) may contribute to the thrombogenic profile of FVL carriers. We measured the plasma level of annexin V-MP (AMP) platelet-MP (PMP), endothelial-MP (EMP), leukocyte-MP (LMP) and tissue factor-bearing MP (TF+MP), and the MP procoagulant activity (PPL) in 142 carriers of FVL (of these 30 homozygous and 49 with prior VTE), and in 142 age and gender-matched healthy individuals. The mean (± SD) level of AMP was 2,802 ± 853 MP/ μl in carriers and 1,682 ± 897 in controls (p<0.0001). A statistically significant difference between homozygous and heterozygous carriers of FVL was seen in the level of PMP, EMP and LMP, but not in that of the remaining parameters. When the analysis was confined to carriers with and without a VTE history, the mean level of AMP was 3,110 ± 791 MP/ μl in the former, and 2,615 ± 839 MP/μl in the latter (p<0.005). The mean level of all subtypes of circulating MP showed a similar pattern. The PPL clotting time was 39 ± 9 seconds (sec) in carriers, and 52 ± 15 sec in controls (p=0.003); and was 35 ± 8 sec in carriers with prior thrombosis, and 41 ± 10 sec in thrombosis-free carriers (p<0.005). Our study results suggest that circulating MP may contribute to the development of thrombosis in carriers of FVL mutation.

The study objective is to determine the possibility of identifying the state of coordination abilities development in girls and boys aged 11-13 using the methodology of multidimensional statistics. Materials and methods: Study participants. The study involved girls: 11 (n=20), 12 (n=23), 13 (n=19) years old; boys: 11 (n=21), 12 (n=20), 13 (n=19) years old. Study organization. The paper used analysis and generalization of scientific literature data, testing, discriminant analysis. Testing procedure. The testing program included well-known tests (Liakh, 2000; Serhiienko, 2001; Ivashchenko, 2016). Study results: The first canonical function explains 65.7% of the results variation, the second one – 25.1%, the third – 4.8%, which indicates their informative value. The coefficients of canonical correlation indicate the prognostic value of these functions. The first canonical discriminant function is most substantially related to the results of tests 4 (r=0.526), 14 (r=0.377), 2 (r=-0.306): therefore, a significant difference between the girls and boys aged 11-13 is observed in the development level of relative and speed strength, movement coordination. The structure coefficients of the second canonical discriminant function indicate that the function is most substantially related to variables 2 (r=0.502), 16 (r=0.434), 9 (r=0.379), 17 (r=0.357): so, a significant difference between the girls aged 12-13 and boys aged 11-13 is observed in speed strength, vestibular stability, and anthropometric data. Conclusions: The discriminant models characterize both age- and gender-related peculiarities of movement coordination development in the girls and boys aged 11-13. The data obtained show significant differences between the groups of girls and boys aged 11-13 both in the structure of coordination abilities development and the level of preparedness, and highlight the need to conduct separate physical education classes for girls and boys. Different programs should be used to develop coordination abilities in boys and girls aged 11-13.
