Area And Volume

This study aims to implement and evaluate a methodological proposal using the hologram as a teaching medium for the learning of concepts related to areas and volumes of geometrical bodies. The study has been carried out with a sample of 78 students in the third year of secondary education from a privately-owned but state-funded school in Madrid. Thirty-five students who have been taught traditionally formed the control group, and 43 formed the experimental group in which the methodology was implemented. To evaluate its goodness, we have used the Student's t-test to assess the existence of significant differences between both groups. The results reported by the test show that there is a difference of 3.9 points between the scores of both groups which is significant at the level of 0.05. In addition, the user experience in the experimental group has also been evaluated to assess the students’ opinions of the hologram in the learning process. The overall results have assisted us in corroborating the efficacy of the hologram as a teaching medium.

Abstract Objectives The relationship between condylar asymmetry and handedness of the patients with temporomandibular disorders (TMD) and patients with no signs or symptoms of TMD was investigated. The experimental group consisted of 25 patients aged 15 to 52 years who were referred for treatment of TMD. The mean age of this group was 26.24 years. The control group consisted of 25 patients aged 14 to 52 years (mean age: 26.16 years). Methods The formula by Habets et al.14 was used to express the symmetry between the condyles and the rami on the orthopantomogram (OPG) image. Differences between bothgroups and subgroups (condyle, ramus, condyle plus ramus) regarding symmetry were calculated with the Student's t-test. Results The mean of condylar asymmetry was found to be 11.11 ± 11.03% in the TMD group. However, in the control group, the mean of condylar asymmetry was found to be 8.36 ± 6.27%. No statistically significant differences were found between condylar asymmetry in both groups (p>0.05). Conclusions No statistically significant differences were found between condylar asymmetry index in patients with TMD according to myogenous problems and in patients with no signs or symptoms of TMD.

Introduction Proteinuria causes lipid metabolism abnormalities. Material and methods The study included 60 patients (M:F 32:28), mean age 37.15? 9.85 years, with average glomerular filtration rate (GFR) 86.27? 19.81 mL/min, and average BMI 24.18?2.23 kg/m2. Regarding the level of glomerular proteinuria, patients were divided into four groups. The first group, with proteinuria levels less than 0.25 g/24h, included 15 patients (M:F 6:9) (control group), average age 34.66?4.82 years, with mean GFR 99.70? 12.94 mL/min, and mean BMI 23.28?3.50 kg/nr. The second group, with proteinuria between 0.26 and 1.0 g/24h, comprised 15 patients (M:F 9:6) with primary glomerulonephritis, mean age 37.87?9.65 years, with mean GFR 82.85?18.48 mL/min and mean BMI 23.83?1.57 kg/m2. The third group consisted of 15 patients (M:F 8:7) with primary glomerulonephritis, with proteinuria between 1.1 and 3.0 g/24h, average age 35.67? 13.29 years, mean GFR 82.85?I8.48 mL/min, and mean BMI 23.83?1.57 kg/m2. The fourth group, with proteinuria over 3.0 g/24h, included 15 patients (M:F 9:6) with primary' glomerulonephritis, mean age 40.40?9.75 years, with mean GFR 80.16?20.80 mL/min, and mean BMI 24.83?1.44 kg/m2. In order to assess the influence of proteinuria on apoprotein metabolism abnormalities we investigated apo A-l apo B, apo E and the apo A-I/apo B ratio. Results Results were statistically analyzed using Student's t-test, and the Mann-Whitney U test. Statistically, patients with proteinuria over 3.0 g/24h have significantly higher apoprotein B and apoprotein E values in the serum, as well as apo B/apo A-l compared to control subjects, and patients with proteinuria around 0.26-1.0 g/24h and proteinuria around 1.1-3.0 g/24h. Proteinuria leads to deterioration of apoprotein abnormalities. .

The research is devoted to the study of the effect of socio-psychological training on the development of pedagogical abilities in rising teachers. The study involved 88 full-time five-year students of the Xxxx Academy (Moscow) and four-year students of Xxxx University (Taldykorgan). The goal was achieved based on a system of special tasks with the involvement of socio-psychological trainings. The experiment and research were carried out for 6 months. The standard devia-tion in the sample and the Student's t-test were studied for the experimental and control groups. The result of the post-test is the opposite; thus, the mean value of the experimental group is higher than that of the control group. The study re-vealed that there is a weak positive relationship between age and pedagogical abil-ities (r <0.2). The results of the study also indicate a positive correlation between gender and pedagogical abilities (r> 0.3). Thus, in accordance with the goal set, it was determined that socio-psychological training improves students' pedagogical abilities. The results of this study can be recommended to teachers of universities and training centers, as well as pedagogical students.

This study breaks away from the immobility experienced by quality control systems in higher education. The authors, following the Sustainable Development Goals (SDGs) on quality education set by the United Nations, propose a questionnaire delivery system through mobile messaging services that overcomes the problem of the low response rates of students for these surveys. The research follows an experimental design, is developed over three years, and involves 811 subjects who are distributed in two groups: an experimental group, in which the questionnaires are delivered through mobile messaging services, and a control group. The researchers examine the existence of differences in response rates through a descriptive comparative exploration between the two groups, also applying the Student’s t-test to evaluate the significance of the findings. The results reveal that the rates for the experimental group are not only higher than those achieved for the control group but are also significant. The authors conclude that the delivery of surveys through mobile messaging services significantly increases response rates. This fact improves the representativity of the information collected and meets the goals of the quality control system with greater certainty.

Abstract Background This study was done to observe the incidence of Osteo-line on the femur neck and to explore the clinical application of Osteo-line in osteotomy. Methods Eighty-nine adult femur specimens were selected to observe the incidence of Osteo-line on the femur neck. From August 2015 to January 2019, a total of 278 patients who completed unilateral hip arthroplasty at the Third Hospital of Hebei Medical University were retrospectively included. Patients who accepted osteotomy via Osteo-line on the femur neck were defined as the experimental group (n = 139), and patients who accepted osteotomy via traditional method (The femoral distance 1.5 cm above the trochanter was retained for osteotomy by visual inspection.) were defined as the control group (n = 139). According to the postoperative pelvic X-ray, Photoshop was used to evaluate the leg length discrepancy (LLD) by the CFR-T-LT method. Results Among the 89 specimens, the incidence of anterior Osteo-line was 75.28%, and the incidence of posterior Osteo-line was 100%. According to the clinical application results, the incidence of anterior Osteo-line on the femur neck was 80%, and the incidence of posterior Osteo-line was 100%. The Osteo-line was clearer than those on the femoral specimens. Twenty-six cases had LLD greater than 1 cm (9.29%), including 2 cases in the experimental group and 24 cases in the control group. The average postoperative LLD in the experimental group (0.19 ± 0.38 mm) was significantly shorter than in the control group (0.54 ± 0.51 mm)(P = 0.005). Conclusion The incidence of Osteo-line on the femur neck was high, and patients who accepted osteotomy via Osteo-line on the femur neck can achieve shorter postoperative LLD than the control group.

AbstractThe objective of this article is to analyze the didactic functionality of a chatbot to improve the results of the students of the National University of Distance Education (UNED / Spain) in accessing the university in the subject of Spanish Language. For this, a quasi-experimental experiment was designed, and a quantitative methodology was used through pretest and posttest in a control and experimental group in which the effectiveness of two teaching models was compared, one more traditional based on exercises written on paper and another based on interaction with a chatbot. Subsequently, the perception of the experimental group in an academic forum about the educational use of the chatbot was analyzed through text mining with tests of Latent Dirichlet Allocation (LDA), pairwise distance matrix and bigrams. The quantitative results showed that the students in the experimental group substantially improved the results compared to the students with a more traditional methodology (experimental group / mean: 32.1346 / control group / mean: 28.4706). Punctuation correctness has been improved mainly in the usage of comma, colon and periods in different syntactic patterns. Furthermore, the perception of the students in the experimental group showed that they positively value chatbots in their teaching–learning process in three dimensions: greater “support” and companionship in the learning process, as they perceive greater interactivity due to their conversational nature; greater “feedback” and interaction compared to the more traditional methodology and, lastly, they especially value the ease of use and the possibility of interacting and learning anywhere and anytime.

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.
