Student’S T Test

The aim of this study was to determine the impact of motor abilities on mastering an obstacle course and define quantitative differences in basic motor abilities between the students awarded poor grades and the students awarded higher grades based on the result achieved on the obstacle course designed to test motor skills. The results of regression analysis demonstrated that motor abilities are important for mastering an obstacle course for testing motor skills and, on the basis of them, we may predict the result that defines the students' specific skills. Moreover, the results of the Student's t-test for independent samples demonstrated a statistically significant difference in the level of motor abilities between the students awarded poor grades and those awarded higher grades. The difference is defined by statistically significantly better values of the results achieved on motor tests: the maximum number of sit-ups (MPTP), stick mobility (MOKP), hand tapping (MTAP) and Cooper's 12 minute run test (MKUP), achieved by the students with higher grades, based on which we can assume that these variables are predictive of successful mastery of the obstacle course for testing motor skills. The results obtained might contribute to a better organization of training work in teaching, especially regarding an approach to improving motor abilities that dominantly have an impact on mastering an obstacle course designed to test motor skills.

The aim of this study was to determine the effects of a sports games experimental program on improving specific motor abilities in adolescents with mental impairment. The study was conducted on a sample of 60 adolescents diagnosed with mild mental impairment, divided into two groups (experimental group EG, and control group CG) with an equal number of participants. The special program of sports games lasted for 12 weeks, with a weekly frequency of four times and a duration of 30 minutes per training. The participants of both groups were tested with the same variables within the specific motor skills for the sport of football and basketball. After a twelve-week experimental program of sports games, there were statistically significant improvements in the EG in the variables: SMFS, SMDR, SMCP with a statistical significance of r=0.000. The results of the ANOVA and MANOVA analyses indicated that after the application of the specific sports games program there was a statistically significant difference in the benefits for the EG compared to the CG, in the parameters of specific motor abilities with a statistical significance r=0.000 and the size of the impact. Based on these research results, it can be concluded that a specific exercise program conducted within twelve-week training of specifically dosed sports activities has significantly contributed the development of specific motor skills for football and basketball.

The aim of this research is to confirm differences in the anthropometric characteristics and motor abilities of schoolchildren aged 9 and 10 compared by sex and age. The sample comprised 341 schoolchildren, divided into two subgroups of third (172) and fourth (169) graders. The research is of a transversal character and includes the measurement of anthropometric characteristics and motor abilities by applying the Eurofit fitness testing battery. The results show a significant difference based on sex in terms of body mass (t = 2.148), and as for motor abilities, there is a difference in the Shuttle run test (t = -3.709). A statistically significant difference considering the age of the tested population was observed in height (t = -10.327) and body mass (Z = -5,991), while in terms of motor abilities there was a statistically significant difference in the values of all the tests: Hand tapping (t = 4.735), the Standing long jump (Z = -3,575), Shuttle run (t = 12,248), the Flexed arm hang (Z = -2,167), Sit and reach (Z = -2,406), Sit-ups in 30 seconds (t = -9069). The research shows a higher statistically significant difference observed in body composition, but also in the motor area of the studied group in terms of age, and in relation to the statistically significant difference that was revealed by gender.

AIM: The aim of this study was to verify two different types of interfaces in Morse taper connection implants, relating the mechanical resistance to a loosening torque that is required to separate or move the prosthetic abutment. MATERIAL AND METHODS: Ten Morse taper connection implants and their respective abutments were divided into two groups (n = 5), DH (double hexagon) interface and OI (octagonal implant) interface. A standard insertion of implants was performed in a stainless steel base, where each abutment received a sequence of two consecutive tightening torques at a 10-minute interval, followed by a loosening torque, which was measured using a digital torque gauge. The Student’s t-test with a 5% significance level was used for data analysis. RESULTS: The results showed a statistically significant difference in the loosening torque values compared with DH torque values (p < 0.05). However, the difference between tightening and loosening torque values was not statistically significant in the OI group (p = 0.465). CONCLUSION: The study concluded that there was a difference in the torque required to loosen the abutment screws between the DH group and the OI group, with the latter showing better results.

The research was conducted on a sample of 70 respondents-swimmers aged 13-15 years of swimming clubs from Sarajevo Canton/Federation of BiH, with the aim of determining the significance and magnitude of the impact of selected basic motor skills on the implementation of specific motor tasks in swimming (navigability in place, sliding length with reflection from water, start from starting block, parallel). The study used 10 variables to assess basic motor skills, which were the input or predictor set of variables, and three variables to assess the efficiency of specific motor tasks in swimming as a criterion, each variable from the battery of specific motor tasks was considered as a criterion on the predictor set of basic-motor variables. Three mini regression analyzes were applied to determine the statistical significance and relative influence of basic motor skills on the realization of specific motor tasks in swimming (buoyancy in place, length of sliding with reflection from water, start from the starting block, parallel). The results of regression analyzes indicate that the greatest influence on the overall efficiency in the implementation of specific motor tests in swimming, looking at all criterion variables together, from the set of basic-motor variables, as a predictor set, show the following variables: stick twist-MFLISK MFLPRK, plantar flexion-MFLPL, long jump from place-MFESDM, agility on the ground-MKOKNT and shelter in lying-MRCZTL. The results obtained in this research can be useful for teachers and swimming trainers who work with younger age categories for the purpose of better programming of training work and selection of training content.

ABSTRACT Objective: To assess the impact of the “Dentistry for Infants” early dental care program run by Jacareí County (SP) by comparing the caries of individuals participating and not participating in this program. Methods: In total, 300 children between 0 and 48 months old were assessed in the following two groups: infants not participating in the program (G1, n = 100) and infants participating in the program (G2, n = 200). Each group was further divided according to age in subgroups of 0 to 24 months and 25 to 48 months. All children were clinically assessed for carious lesions using the visual-tactile method. The data were statistically analyzed using a paired Student's t-test, Mann-Whitney test, and χ2 test at a 5% significance level. Results: There was a significant difference in the prevalence (P) and mean index of deciduous teeth (deft) (C) that were decayed, indicated for extraction and filled, and the highest values were observed in G1 (p < 0.0001). The values were as follows: PG1, 73%; PG2, 22%; CG1, 3.45 ± 3.84; and CG2, 0.66 ± 1.57. Conclusion: Participating in the program positively impacted the infants’ oral health.

Background. Knowledge and psychomotor skills are essential in dental education. The aims were to (1) investigate the correlation between dental students’ didactic and psychomotor skills performance in the dental anatomy and preclinical operative dentistry courses and (2) explore the impact of gender on students’ performance in both courses. Materials and Methods. A retrospective cohort study was performed on dental students’ (164 students; 72 males and 92 females) dental anatomy and preclinical operative courses scores of the same class over 2 years (2018–2020). Didactic and practical scores were collected. The didactic scores included examinations. Practical scores included tooth wax carving for the dental anatomy course and class II cavity preparations and restorations for the preclinical operative. Student’s t-test and ANOVA were used to analyze the difference between the didactic and psychomotor skills scores of both courses and genders. Pearson’s correlation coefficient was used to explore correlations ( p < 0.05 ). Results. Moderate, positive, and significant correlations were found between didactic scores in both courses and between dental anatomy’s didactic and psychomotor skills. A weak, positive, and significant correlation existed between the preclinical operative didactic and psychomotor silks ( p < 0.05 ). Females’ didactic performance was significantly better than males. Gender had a significant, positive, and moderate correlation in the dental anatomy course, but moderate-weak in preclinical operative ( p < 0.05 ). Conclusion. Students’ didactic and psychomotor performance correlations in dental anatomy and preclinical operative courses were positive. The correlation was moderate and weak and varied by course. Gender had a significant impact on student performance and varied by procedure and courses investigated.

Background and Study Aim. To investigate how bilateral pedaling asymmetries change at exercises with different levels of intensity. Material and Methods. Eight students of cycling, average age 25.4 years, were investigated. In the experiment, we recorded the pedal force of the right and left legs during three consecutive exercises of different intensity 35%, 55% and 85% respectively.  To quantify the difference in physical parameters of pedaling between the left and right legs, we used two approaches that complement each other in the analysis of bilateral asymmetry. One approach involved determining an asymmetry index, and other was statistical analysis. Results. The Student's t-test indicated that the difference between the power samples for the left and right pedals decreased at 85% exercise intensity vs. 55% with a statistical significance of α = 0.05. The bilateral asymmetry in most cases decreased or in two cases remained unchanged. The cases where there was no statistically significant difference between the power samples for both legs at 85% and 55% intensity levels had the lowest asymmetry index. Conclusions. The bilateral pedaling asymmetry is reduced at 85% exercise intensity compared to the 55% one. The reduction in asymmetry index ranges from 1% to 14.1%, Combining the asymmetry index and the Student's t-test can increase the informativeness of pedaling power data when analyzing bilateral asymmetry.

Objective: To investigate the impact of the phonetic content of two sentence sets on speech outcomes, specifically the effects of nasal phonemes. Method: Audio-video recordings of a consecutive series of 15 participants (age range 4–22 years), with cleft palate (syndromic or non-syndromic), with and without velopharyngeal dysfunction were taken. Participants repeated Sentence Set 1 (with nasals across sentences) and Sentence Set 2 (without nasals except the three nasal target sentences) during a routine speech recording. Two experienced Specialist Speech and Language Therapists, blinded to the study’s purpose, analyzed participants’ speech using the Cleft Audit Protocol for Speech-Augmented (CAPS-A). On day 1, recordings included Sentence Set 1. On day 2, 23 days later, recordings included Sentence Set 2. Main results: The difference between Sentence Set 1 and Sentence Set 2 ‘total scores’ (sum of scores on all CAPS-A parameters) was significant. The Pearson Product Moment showed high correlation. A Wilcoxon test revealed a significant difference between Sets 1 and 2 on the hypernasality parameter, and this alone accounted for the significant difference in total scores. Conclusion: The inclusion or exclusion of nasal consonants in the sentence set significantly affected perceptual ratings of hypernasality but none of the other CAPS-A parameters, highlighting the need for further investigation into perceptual nasality ratings.

Objective: Metabolic syndrome is a cluster of disease condition characterized by truncal obesity, hypertriglyceridemia, elevated blood pressure, and insulin resistance. An excessive circulating uric acid (UA) level even within normal range is always comorbid with metabolic syndrome and its components. The aim of the current study was to investigate the association between metabolic syndrome and serum UA level.Methods: A total of 60 subjects were divided into two groups of healthy (30 individuals) and metabolic syndrome patients (30 individuals) from dental outpatient department of Saveetha Dental College and Hospitals. 5 ml of fasting venous blood was collected in the plain collection tubes and centrifuged, and then serum was separated. Then, the serum was used to analyze the fasting blood glucose, serum triglycerides (TGLs), and serum UA by GOD-POD, enzymatic colorimetric, and uricase method, respectively. A statistical analysis was performed using Student’s t-test. p<0.05 was considered to be statistically significant.Result: Mean body mass index (BMI), fasting blood sugar (FBS), TGL, and UA level of control group were 23.36±1.81, 84.45±13.1, 110.9±22.6, and 3.48±1.21 respectively. Mean BMI, FBS, TGL, and UA level of study group were 35.24±3.04, 122.85±23.3, 212.1±39.6 and 9.08±2.63 respectively. There is a significant difference between these two groups with p<0.0001.Conclusion: This study showed that those individuals with metabolic syndrome have higher UA level that indicates hyperuricemia which is a significant predictor of metabolic syndrome.

ABSTRACT The objective of this study was to investigate the effect of the ketoprofen on the preemptive analgesia in female cats submitted to ovariohysterectomy. Sixteen healthy cats were distributed into two groups, with eight animals each, by means of a draw, in a preemptive group (PREG), in which the animal received ketoprofen (1 mg/kg) subcutaneously two hours before the surgery; and postsurgery group (POSG), in which ketoprofen (1 mg/kg) was administered subcutaneously immediately after surgery. In both groups, ketoprofen was given 24, 48 and 72 hours after the first adminstration. Heart and respiratory frequencies and glycemia were measured in all animals during the days first ten postsurgery. Analgesia was measured by assigning scores at zero, two, four, six, 12, 24, 48, 72, 96, 120, 144, 168, 192, 216 and 240 hours after the surgical procedure. Statistical analysis was performed using two-way analysis of variance followed by Tukey's test to compare the moments and Student's t-test for comparison between groups. Pain scores were evaluated using test of U-Mann-Withney or Kruskall-Wallis, all at the 5% level of significance. Pain scores were significantly lower in PREG in M0, M6, M72, M96 and M120. No significant difference was found in the levels of glycemia in comparison to baseline values. Ketoprofen promotes postsurgery analgesia in female cats submitted to ovariohysterectomy and preemptive and postsurgery administration provides an earlier reduction of pain scores when compared to postoperative administration, only.
