About means of development of stochastic thinking of students in the system of secondary vocational education

This article presents specificity of the learning process of mathematics in the OSS system. It makes the attempt to reveal the structure of stochastic thinking and presents the principles and means of teaching mathematics, contributing to the improvement of stochastic competence and the model of teaching mathematics in the OSS system with the aim of developing stochastic thinking of students

Assessment of the psychophysiological and functional state of basketball students in the pre-competition period

Objective: to assess the psychophysiological and functional state of the body of basketball students in the pre-competition period.Materials and methods: the study involved female basketball students with a sports category (girls, n = 18) in the pre-competition period. The article presents an analysis of the results of the psychophysiological and functional state of the body of the examined, obtained through the use of complex control using psychodiagnostic and functional research methods.Results: indicators of psychodiagnostic techniques characterize the insufficient development of the studied properties of attention for those engaged in playing sports and the fitness of the functional abilities of the leading hand of basketball players. The revealed data of the tapping test correspond to the criterion of the lower limit of optimal performance, which causes insufficient physical readiness for competitive activity. The obtained results of temporal and spectral indicators of heart rate variability were not typical for students engaged in playing sports, which causes an increase in the degree of tension of regulatory systems and characterizes the development of fatigue in the pre-competition period of the surveyed athletes. The use of the spirometric method determined the discrepancy between the results obtained and the proper values characteristic of the weight and height parameters of the subjects, which indicates violations of the ventilatory function of the lungs and reduced respiratory musculature capabilities of basketball students.Conclusion: the analysis of the obtained data on the psychophysiological and functional state of the body of basketball students in the pre-competition period determines the need to build a training process with the inclusion of psychological and pedagogical training aimed at expanding the physiological reserves of functional systems, improving the psychomotor properties of the body that determine the success of competitive activity and increasing the share of training effects aimed at improving the quality of strength endurance

Abscess Formation Following Spilled Gallstones During Laparoscopic Cholecystectomy

A review of the English literature concerning spilled gallstones during laparoscopic cholecystectomy is compared with one institution's experience of four cases during 1,726 laparoscopic cholecystectomies performed over a four-year period. Strategies regarding management and treatment are discussed
