The paper presents some considerations about medical waste management in private medical facilities which are considered to be small generators of such waste. The regulations are also applicable in these facilities and the management must develop strategic plans for minimizing the amount of medical waste. Some examples are revealed and a statistical analysis is conducted in order to reveal the efficiency of the medical waste management system. A forecast of hazardous medical waste is determined using the moving average method.

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.

The consolidation of topsin, the most prolific technical & tactical element in the attack’s area, requires, besides the daily training and efficient biomechanics, an optimal health of the osteo-articular and muscular system, due to the fact that the performance of this element requires forceful speed developed throughout the muscle chain. The purpose of the present scientific research is to identify the problems occurred at spine level resulted following to topspin attack and the importance of this technical element in the female junior’s performance. The social enquiry-based survey was conducted on a number of 27 coaches and athletes, using a number of 15 questions. Objectives: optimization of topspin attack in 11-12 years old female juniors. Premises: the knowledge on statistics of spine specific areas generating pain at the time of the attack will allow us to create a postural correction program meant to optimize performance. Research methods: The registration method was based on an opinion poll, on a statistical and mathematical method, on computer graphics method. Conclusion: around 78% of the interviewed specialists consider that the lumbar area is the most affected and predisposed to pain in case of topspin, existing a strong correlation between it and the technical element considered to be the most important in the attack phase (topspin – 66.67%) in female juniors, p = 0.003 < α = 0.05, V = 0.620 and C = 0.659.
