<p>The advent of technology has improved the way statistics is taught and learned. It is claimed that the use of computer-based instructional tools can actively explore the meaning of statistical concepts among the students, as well as enhance their learning experiences. This study aimed to compare three methods of statistical analysis namely, the traditional technique (use of the calculator), Microsoft Excel and Statistical Package for Social Sciences (SPSS) software. This investigation utilized the experimental design, specifically the One-Group Pretest – Posttest Design. There were six education students who self-assessed their attitude before and after the introduction of the use of various computation techniques and performed the statistical analysis considering also the completion time required for each process. Results of the study revealed an increase in the level of attitude among the respondents form the pretest to the posttest. Also, the cognitive level regardless of the approach was very high. However, the t-test failed to establish a significant difference in the attitude among the respondents. On the other hand, there were significant differences in both the test scores and completion time of the respondents in the three methods in favor of SPSS.</p><p> </p><p><strong>Keywords: </strong>Information technology, statistics, traditional technique, Microsoft excel, SPSS, comparative analysis, experimental research design, Davao City, Philippines. </p>

ABSTRACT The objective of this study was to assess the effectiveness of three surface friction techniques for the removal of organic material. A quantitative, descriptive and exploratory study was developed to evaluate the presence or not of organic material before and after the cleaning and disinfection process of surfaces of bedside tables of patients hospitalized at an Intensive Care Unit. Three friction techniques were executed in the one-way, two-way and centrifugal sense, individually, three times on each table, during alternate weeks. For each patient unit and friction technique, a single table and three sides of cloth were used, moistened with 70% (w/v) alcohol. The organic matter was detected through the presence of adenosine triphosphate by bioluminescence, using 3M(tm) Clean-Trace(tm) ATP Systems. For each technique, 13 samples were collected before and 13 after the cleaning/disinfection process, totaling 78 samples of adenosine triphosphate by bioluminescence. No statistically significant difference was found among the removal techniques of organic matter. This study demonstrated that none of the three surface friction methods was better than the other to remove organic matter. Nevertheless, further research is needed in which other cleaning/disinfection indicators and surfaces are considered.

Background/Objectives: This study examined the effects of introducing programming as a technological tool for teachers’ Technological Pedagogical Content Knowledge (TPACK) development.Methods/Statistical Analysis: Thirty-two teachers were divided into two groups, completing different types of TPACK educational programs. The control group’s TPACK training program was based on information and communication technology (ICT), while that of the experimental group was based on programming. To verify the effectiveness of the TPACK training program, tests were administered before and after the educational program. A statistical analysis of questionnaire results also investigated changes resulting from TPACK.Findings: Both the control and experimental groups showed statistically significant improvements in the post-test compared with the pre-test. However, in the detailed areas of TPACK by group, the improvements in the two groups differed. Unlike the control group, the experimental group showed a statistically significant improvement in the knowledge related to technology. This result illustrated that programming is effective in solving the problem of integrating technology into the classroom. In contrast, there was no significant difference in the post-test, as this was applied in the short term. However, programming has been shown to affect Technological Pedagogical Knowledge (TPK), Technological Content Knowledge (TCK), and TPACK. In summary, the results showed that a TPACK educational program based on programming is effective for teachers’ TPACK development. Keywords: TPACK, In-service teacher, Programming, TPACK-P, Educational program

AbstractThe objective of this study was to describe current obstetric, neonatal, and long-term neurodevelopmental outcomes of higher order multifetal gestations (≥ 3 fetuses) in the 1990s. We also intended to identify a target gestational age at which neonatal and neurodevelopmental morbidities are low. Records from all multifetal pregnancies (≥ 3 viable fetuses ≥ 20 weeks gestation) delivered at the two perinatal centers in Toronto, Ontario, Canada during the study period (January 1, 1990–December 31, 1996) were reviewed. Data were collected on obstetric, neonatal, and long-term neurodevelopmental outcomes. Follow up data were gathered regarding the presence of a severe deficit in four categories (vision, hearing, cognition, and motor skills). Statistical analysis was performed to determine a gestational age at which a significant decrease in deficit occurred. During the study period 165 multifetal pregnancies were delivered. This resulted in 511 fetuses, of which 496 were live births. Of these 496 infants, 453 survived to discharge. Follow up data were obtained on 332 (73.3 per cent) infants. Infant survival increased with gestational age, and was approximately 90 per cent or greater at 26 weeks or more. Of all infants followed, the proportion of those without deficit increased with increasing gestational age, such that the per cent without deficit was 96.9 at 31 weeks or greater. Of all infants followed, 301 (90.7 per cent) had no deficit. Statistical analysis revealed a significant difference in long-term neurodevelopmental outcome between infants born before and after 28 weeks gestation. The incidence of a major deficit was 44.1 per cent for those born earlier than and 5.4 per cent for those born later than this gestational age (p = 0.001). In our cohort, survival figures were high. Even in lower gestational groupings, survival was high, but not without serious concerns about severe morbidity. This information is useful when counseling parents of higher order multifetal pregnancies.

One of the tasks of the development of children aged 11-15 years is to think in a more abstract and logical way and more idealistic thinking. This ability to think will be disrupted if teenagers have difficulty concentrating during learning. Therefore we need a method that is fun and can make children relax in learning so that they can concentrate their concentration on ongoing learning. One method that can be used is the Murrotal Al-Qur'an therapy. The aim of the study was to determine whether there was any effect of murottal therapy on the concentration of students at Muara Enim 2 MTsN. This study used a quasi-experimental design with the design of the one group pretest posttest. The sample used was all students of class VIII.G at MTsN 2 Muara Enim. The results showed that the average concentration score of class VIII.G students before Murottal therapy was given was 10.84 with a standard deviation of 3.043. While the average concentration score of class VIII.G students after being given murottal therapy was 17.90 with a standard deviation of 1.233, so that the difference in mean concentration scores before and after murottal therapy was 7.06 with a standard deviation of 1.81. Wilcoxon signed ranks test obtained ρ value = 0,000, with a value of α = 0.05 (p <0.05), this shows that there is a significant difference between the concentration of students before and after being given murottal therapy. It is expected that the school can make a policy about the application of murottal therapy in increasing student concentration.

<p><strong>Objective:</strong> To evaluate the effect of glide path creation on transportation promoted by NiTi and M-Wire instruments. <strong>Material and Methods: </strong>Sixty polyester resin blocks containing a simulated root canal were distributed into four groups (n=15), according to the protocols/systems used for root canal preparation: GPR group - glide path + Revo-S system; R group - no glide path + Revo-S system; GPPN group - glide path + ProTaper Next system and PN group - no glide path + ProTaper Next system. Root canals were photographed before and after preparation, and the images were superimposed to evaluate the transportation at the apical, middle and coronal thirds. The time spent to perform preparation was also measured (seconds). Data were submitted to the non-parametric Kruskal-Wallis test (p&lt;0.05) for statistical analysis. <strong>Results:</strong> In the apical third, there was no significant difference among groups (p&gt;0.05). GPR and R groups were similar in the middle third (p&gt;0.05). However, the transportation value in GPR group was statistically higher in comparison with GPPN and PN groups (p&lt;0.05). In the coronal third, GPR and R groups were similar (p&gt;0.05). Only R group presented significant difference in comparison with GPPN and PN groups (p&lt;0.05). There was no difference among groups about time spent to perform preparation (p&gt;0.05). <strong>Conclusion:</strong> None of the systems were capable of maintaining the original trajectory of the simulated root canal, and the glide path had no effect on the transportation promoted by instruments.</p><p><strong>Keywords</strong></p><p>Dental instruments; Endodontics; Root canal preparation.</p>

ABSTRACT Objectives: To study the effect of water, halloumi cheese and sugar-free (SF) chewing gum on plaque pH recovery after the intake of sweetened PLAs. Settings and Design: A randomized clinical trial was conducted on 17 children (10 females, 7 males) aged 11–12 years with DFT/dft of more than 3. Materials and Methods: Each volunteer tested paracetamol and ibuprofen suspension alone or followed with water, halloumi cheese or SF gum, as well as 10% sucrose and 10% sorbitol as controls. Plaque pH was measured using the sampling method before and after 5, 10, 15, 20, 30 min of ingestion. Statistical Analysis: Statistical analysis was performed using analysis of variance followed by least significant difference test to assess minimum pH (min pH), maximum pH drop (ΔpH), and the area under baseline pH, and P value was set as 0.05. Results: Both ibuprofen and paracetamol were not significantly different from 10% sucrose in terms of min pH, ΔpH, and area under baseline pH except for min pH of ibuprofen (P = 0.034). Water and halloumi cheese did not have a significant effect on plaque pH recovery after the intake of both analgesics as min pH, ΔpH, and area under baseline pH were similar to 10% sucrose except for min pH of ibuprofen + water (P = 0.048). However, plaque pH variables after chewing SF gum for 20 min were similar to 10% sorbitol. Conclusion: Chewing SF gum immediately after the intake of sweetened PLAs for 20 min restores plaque pH and could be recommended as a complementary aid in caries prevention.

Objective: This study sought to evaluate how a high-fidelity computer-based sonography simulator (FCBSS) can be used in training obstetrics and gynecology residents and evaluate efficacy of high-fidelity CBSS in enhancing resident’s sonographic knowledge, psychomotor skills, and level of confidence in performing sonographic fetal assessments. Materials and Methods: Eleven postgraduate year 1 residents (PGY1s) and ten PGY2s were assessed on sonographic performance by measuring psychomotor skills and evaluating the accuracy of the sonographic images. PGY2s received traditional sonography training while PGY1s received three individualized training sessions on a high-fidelity CBSS. At the conclusion, all residents received feedback and completed a survey to establish their current confidence level in performing and interpreting sonograms. Results: PGY2s scored a median of 33/66 points on the assessment, while PGY1s scored a median of 64/66 points. Statistical analysis performed from motion analysis metrics between cohorts revealed a statistically significant difference, with PGY1s demonstrating higher psychomotor skills. Interquartile ranges of PGY1s’ scores were smaller than PGY2s’, revealing consistency in knowledge and skills among the PGY1 cohort. Conclusion: Findings suggests that high-fidelity CBSS can be used effectively in training residents. It also demonstrates that implementation of formalized sonography training, using a high-fidelity CBSS, can be achieved and potentially expedite and enhance the learning of novice learners.
