The climate has changed significantly over the past few decades around the globe. To make meaningful comparisons between changes occurring over time in the tree world, comprehensive databases on the most important species and their evolution must be created. It is essential to consider latitude, longitude, altitude and local relief when analyzing data. Given the extensive distribution of oak, hornbeam and ash, a sequence analysis was conducted to definitively examine the characteristics of these species in West Plain, West Hills, Apuseni Mountains and Transylvania's Tableland. The data for all the regions comprised a total of 708511 ha, which were subjected to rigorous analysis to determine characteristics such as yield class, volume, increment, structure and participation percentage. The data was analyzed using the most appropriate modern statistical programs, including correlation matrices, ANOVA, principal component analysis, matrix data analysis and the cluster method. In relation to the altitudinal variation, oak is present at average altitudes of 200–250 m in West Plain, 400–500 m in West Hills and Transylvania's Tableland, and 900–950 m in Apuseni Mountains. Hornbeam has a similar spreading with oak, but records its presence in slightly higher altitudes of West Hills (400–700 m) and lower in Apuseni Mountains (700–750 m). Volume is also an important indicator, as it is susceptible to climate change. Oak has the highest age-volume, over 95 years, while ash and hornbeam have it less than 90 years. The results are crucial for understanding the ecological requirements of oak, hornbeam and ash, as well as for effectively managing these forests.

Introduction. Depressive states and anxiety are common symptoms of children with autism spectrum disorder (ASD). The persons with intellectual disabilities show problems related to the development of basic motor skills, having learning problems compared to normal ones, imbalances between the processes of arousal and inhibition, limited motor ability, difficult understanding of language and motor tasks, difficult concentration, mechanical assimilation etc. Objectives. The study analyzes the effectiveness of structures and motion games, applied in specific activities for children with intellectual disabilities (ID) and autism spectrum disorders (ASD). Material and Methods. The research involved an experimental group of 5 children with one of these disabilities or their combination (age 10-11 years), included in a training process at the Ion Teodorescu Special Vocational School in Slobozia / Ialomița / Romania and comparing their results with a control group (6 normal children, with an average age of 10 years), between 20.09.2020-10.03.2021. The assessment of the level of psychomotor and intellectual development was made by the Cutout Test, the Cohs Cube Test (light task configurations) and an Attention Flexibility Test (movement to the corners of the room/field depending on the assigned color, counting successful attempts and mistakes). Results and discussion. The obtained results confirm the working hypothesis, so the use of the structures and games proposed in the program contributes to a significant improvement of the psychomotor and intellectual performances of students with intellectual disabilities and autism spectrum. Conclusion. espite all these improvements, they cannot approach or equal the reference values of children without problems, falling into the same age category.

Background: Postural skills are fundamental in motor activities, so far no evidence of a direct relationship has been found, it is therefore recommended to consider the following directions, the higher the level of sports competition, the better the body posture; or better athletes also have a better body posture. Around the age of 11-14 years, it is a period of aggressive development, if the rapid growth of the bone system is not associated and symmetrical with the development of soft tissues serious postural deficiencies may develop in table tennis players. Methods: We used the web camera – photographic method (38) related to the Sensor Medica software that allows the acquisition of images in order to detect postural deficiencies and we considered it necessary to have a clear image of the level of technical-tactical training of female juniors III using 5 tests specific to topspin attack in order to assess the influence of body posture on such tests. Eighteen female juniors III (the mean ± SD age, height and weight were 11.1 ± 0.2 years, 147.7 ± 2.6 cm, 39.0 ± 2.0 kg). Descriptive statistical analysis was performed on the procedures for establishing the normality of data distribution, Levene's Test for Equality of Variances, the t test for independent samples. The confidence interval was set at 95% (p < 0.05), Results and Conclusions: Since Sig. (2-tailed) or p < α = 0.001 and taking into account that the confidence interval limits for the difference between the sample mean and the reference value (95% CI for the mean difference) do not contain the zero value, it is accepted that there are statistically significant differences between the shoulder inclination for the female athletes in the sample studied and the reference value. We identified that at the level of alignment between anatomical landmarks, the percentage of deficiency of the entire lot of female juniors III in the case of shoulders is 100% and at the level of PSIS is 66%, which validates several studies that stated that in this period of aggressive growth correlated with repetitive unilateral executions specific to the topspin attack lead to postural deficiencies. In terms of the influence of body posture on the quality level, we identified that Group 1 – (without PSIS imbalance) has a higher average overall efficiency of the 5 tests (11.33) compared to Group 2 (8.58), even if from a statistical point of view these differences are not significant.

The study aims to investigate the parameters offered by the baropodometric examination on a group of athletes practicing the martial art Karate Do (20 subjects, 16 girls and 4 boys, average age 13.55 ± 2.74, height 163 cm ± 8.47 , weight 54.50 kg ± 8.84, BMI (body index mass) of 20.46 ± 2.90 and seniority in sports activity of 5.27 years ± 2.74). The purpose of the research is to determine the changes related to the value of the plantar surfaces, the pressures for the dominant and non-dominant lower segments, the positioning of the pressure center in relation to the support polygon and the imbalances in the sole of the foot. The testing was performed using the FreeMed baropodometric platform and the FreeStep by Sensor Medica software, in the last week of February 2021, at the Research Center for Human Performance within the Faculty of Physical Education and Sports, “Dunărea de Jos” University from Galați. Results: Placing the maximum pressure point / P.max in the forefoot area is an exception, only one case being reported with this distribution, the rest having P.max located at the rearfoot level. Comparison of the averages between the variables recorded for the left foot vs. the right foot highlights higher values of the dominant / right foot, but these differences are significant only for the values of the plantar pressure in the forefoot area and for the total load on the entire plantar surface / total load (p

We have lived in an era in sports history in which due to the intensity of the confrontations between athletes, disorders manifested by headaches, shoulder, pelvis and knee aches etc. appear more often. The performers during puberty require special attention on their morpho – functional development from the kynesiotherapist who is part of the multidisciplinary team, due to many transformations of the human body specific at this age category. 13 juniors female athletes have participated to the study, being assessed anthropometric, plantar pressures and posture with softwear FreeStep by Sensor Medica, biomechanical analysis and from technical & tactical point of view by 5 tests with DartFish 360S. Within the statistical – mathematical analysis, we have used Pearson correlation coefficient which favoured the identification of the strongest correlations resulted from the technical – tactical - anthropometric – plantar pressures and postural unbalances (r > 1.00 at test 1 and r > 0.84 at test 2). Assumption: It is assumed that by using established methods and means to assess postural deficiencies and to assess the level of consolidation of the topspin attack, we can identify the correlations between them which would facilitate the creation in the future of an efficient postural improvement program. The goal is to improve the quality of life and sports performance in junior female table tennis players. The conclusions of this study demonstrate the fact that the mobility of the spine in frontal plan, high thoracic elasticity and an increased lateral mobility on the opposite side of the active arm represent advantages intended to optimize the attack by topspin, while the supraponderability, the pain in lumber area and the shoulder’s asymmetry constitute disruptive factors of attack’s performance.
