"Hight jump is a very important skill in the modern volleyball game. The height of the vertical detachment can be measured in a variety of ways, from the most sophisticated (jumping platform, jumping mats) to those available to all (Sargent test, and Vertec). Through this study we followed the comparative analysis of an alternative method for measuring detachment on the spot, using the G-Vert device, with a device known and currently used by several federations for measuring vertical detachment. Following the application of the Counter-movement jump Test (CMJ) or Static Vertical Test (SVT) and Approach Vertical Test (AVT), the values obtained were recorded, analyzed, and compared using the Microsoft Xcel and IBM SPSS statistical processing and analysis programs. The results of the analysis show small differences between them, which attests to the G-Vert device, as a reliable device for measuring vertical detachment. The G-Vert device, in addition to the ability to record vertical detachment, gives us information about the gravitational force that is exerted on the body during the jump, and the force with which the detachment is performed on the spot, information that can be obtained by the jumping platform. Keywords: G-Vert, high jump, measurements, tests."

Objective: To analyze the behavior of the average height of jumps according to the Body Mass Index, and the sex of subjects, and to find significant differences between the variables measured in the anaerobic test of Counter Movement Jump test over 10 s and 60 s in adolescents according to place of residence. Method: We selected a huge sample of subjects to different places of residence and we categorized them in three levels; Urban – Interior, Urban – Coast and Rural – Interior. Their corporal composition were measured and analyzed, with this analysis we calculated the Body Mass Index, and categorized them by Body Mass Status (Underweight <18.5; Normal Weight 18.5–24.9; Overweight 25–29.9 and Obesity +30). Then, we measured the Jump 10 s. The next day, the Jump 60 s was measured, finding the anaerobic alactic and anaerobic lactic parameters. Results: The highest percentages of overweight and obesity (20.23%) were found in a Rural – Interior area, however, these have in turn the lowest percentages of underweight (10.66%). In the Counter Movement Jump test were not found significant difference in the measured obtained between subjects of Urban – Interior and Urban – Coast areas, but we found significant difference in the remaining comparisons. Conclusions: The significant difference in anaerobic values measured in adolescents, only reside purely in urban and rural areas, rejecting so a possible differentiation from the coast areas.

Introduction. The most susceptible to lead is the hematopoietic system of hematopoietic organs due to lead inhibition of heme and globin synthesis and cytotoxic effect on the membrane of Mature red blood cells. The aim of study was to evaluate the informative value of the study of erythrocyte and reticulocyte parameters determined on modern hematological analyzers in patients working in contact with lead during medical and biological monitoring. Materials and methods. 45 employees of the lead battery processing plant and 30 persons of control group were examined. The level of lead in the blood was determined by atomic absorption spectrometry, δ-ALA in the urine-by the reaction of pyrol formation with acetylacetone in terms of gram of creatinine, the study of hematological parameters was performed on a Sysmex HT-2000i analyzer. Statistical processing of the results was performed using the program STATISTICA 10.0. Results. Significant changes in erythrocytic (RDW) and reticulocytic (RET, IRF, LFR, MFR, HFR, RET-He) parameters, erythropoietin in workers in contact with lead compared to the control group, changes in MCV, MCH, RDW, RET indicators in the group working in dynamics after 2 years were revealed. Associations of hematological parameters with biomarkers of exposure and effect (lead level in blood and ALA in urine) were revealed. Conclusions. Assessment of erythrocyte (MCV, MCH, RDW) and reticulocyte parameters (RET% and their distribution by maturity) in dynamics during periodic medical examinations of workers in contact with lead allows us to detect the development of hematological disorders at early stages.

The research would look further at the representation of the human body in both Balinese and Javanese traditional houses and compared the function and meaning of each part. To achieve the research aim, which was to evaluate and compare the representation of the human body in Javanese and Balinese traditional houses, a qualitative method through literature and descriptive analysis study was conducted. A comparative study approach would be used with an in-depth comparative study. It would revealed not only the similarities but also the differences between both subjects. The research shows that both traditional houses represent the human body in their way. From the architectural drawing top to bottom, both houses show the same structure that is identical to the human body; head at the top, followed by the body, and feet at the bottom. However, the comparative study shows that each area represents a different meaning. The circulation of the house is also different, while the Balinese house is started with feet and continued to body and head area. Simultaneously, the Javanese house is started with the head, then continued to body, and feet area.

BACKGROUND Since November 2019, Covid - 19 has spread across the globe costing people their lives and countries their economic stability. The world has become more interconnected over the past few decades owing to globalisation and such pandemics as the Covid -19 are cons of that. This paper attempts to gain deeper understanding into the correlation between globalisation and pandemics. It is a descriptive analysis on how one of the factors that was responsible for the spread of this virus on a global scale is globalisation. OBJECTIVE - To understand the close relationship that globalisation and pandemics share. - To understand the scale of the spread of viruses on a global scale though a comparison between SARS and Covid -19. - To understand the sale of globalisation present during SARS and Covid - 19. METHODS A descriptive qualitative comparative analysis was used throughout this research. RESULTS Globalisation does play a significant role in the spread of pandemics on a global level. CONCLUSIONS - SARS and Covid - 19 were varied in terms of severity and spread. - The scale of globalisation was different during the time of SARS and Covid - 19. - Globalisation can be the reason for the faster spread in Pandemics.

Summary Background: It has been reported that obesity is associated with metabolic syndrome, insulin resistance, cardiovascular risk but also with nonalcoholic fatty liver disease (NAFLD). The prevalence of obesity in children and adolescents is increasing rapidly all over the world. The aim of this study was to analyze the value of liver enzymes: AST, ALT and γGT in a group of obese students in order to establish their correlation to anthropometric parameters such as: BMI (body mass index), WC (waist circumference), HC (hip circumference), and WHR (waist-to-hip ratio) compared to non-obese students who comprised the control group (CG). Methods: In this study, 238 students from the University of Novi Sad of both sexes (126 men and 112 women) with a mean age of 22.32 ± 1.85 years were included. According to the body mass index (BMI) lower and higher than 25 kg/m2 and waist circumference (WC) lower and higher than 94 cm (80 cm for females) the whole group of 238 students was divided into 2 subgroups: the obese group at increased risk for CVD (Group 1) and the group at lower risk for CVD (Group 2). AST, ALT and γGT activities were determined in fasting blood samples. Results: Statistical processing data revealed significantly higher values of AST, ALT and γGT in the group of students with BMI>25 kg/m2, WC>94 cm for males and WC>80 cm for females, HC>108 cm for males and HC>111 cm for females, and WHR>0.90 for males and WHR>0.80 for females (P<0.001). Significant association was established between anthropometric parameters and liver enzyme levels (P<0.0001). Conclusions: Obese students with higher BMI, WC, HC and WHR values have higher liver enzyme activites and a higher chance to develop NAFLD in the future.
