In physics, computer-based tests have been widely developed, however, the questions are only presented in textual and pictorial representations. We have developed a kinematic test in the multimedia format, which is so called multimedia-based test (MBT). For comparative study purposes, two groups of students were alternately set to take the MBT and paper-based test (PBT). From the statistical analysis, it is revealed that there was no significant difference between the MBT and PBT. Therefore, the MBT can be used for reliable assessment tool. We also found that students were more motivated to work on multimedia format.

<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>

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.

ABSTRACT Background Postoperative pain, swelling and trismus are the most common outcome after third molar surgery. Many methods have been tried to improve postoperative comfort after surgery. Ketamine is a phencyclidine derivative that induces a state of dissociative anesthesia. It is a noncompetitive N-methyl-D-aspartate (NMDA) receptor antagonist and has a distinct suppression effect on central nervous system (CNS) sensitization. Ketamine in a subanesthetic dose is set to produce analgesic and anti-inflammatory effect. Materials and methods Sixty patients, between the age group of 18 and 38 years, undergoing the extraction of impacted mandibular third molar, reporting to the department of oral and maxillofacial surgery were included in the study. Patients were divided randomly into two groups: local anesthetic alone (LAA) and local anesthetic and ketamine (LAK). Statistical analysis Statistical analysis was performed using the Mann-Whitney U/unpaired—t-test and Wilcoxon signedrank test. Result There was a significant difference in mouth opening in the LAA and LAK group in the immediate postoperative period. There was a significant difference between the two groups after 1 hour (LAA: 2.37; LAK: 1.40), and 4 hours (LAA: 2.37; LAK: 1.40). There was a significant difference in terms of facial swelling in the immediate postoperative period and day 1 between the LAA and LAK group. Clinical significance Use of subanesthetic dose of ketamine is not only safe but also valuable in reducing patient morbidity after third molar surgery. Conclusion Combination of a local anesthetic and subanesthetic dose of ketamine during surgical extraction of third molars provides good postoperative analgesia with less swelling and significantly less trismus.

PURPOSE: Compare the parietal peritoneum suture and nonsuture in midline laparotomies in rats, as for the formation of adhesions. METHODS: 40 adult albino Wistar rats (20 males and 20 females) underwent a surgery, weighing between 350 and 400 grams. After anesthesia, a midline laparotomy was performed, followed by cavity closure with and without peritoneum suture. After 40 days, the rats underwent a new surgery in order to verify the peritoneum and check if there were any adhesions, and the rats were then sacrificed. RESULTS: Statistical analysis showed there was no significant difference between the adhesions occurring or not with peritoneal suture or nonsuture, including in relation to the rats' gender. CONCLUSION: Closing the peritoneum or not does not interfere with the formation of adhesions after midline laparotomies in rats from both genders.

This article identifies the determinants of party loyalty while making a distinction between government and opposition voters within an electoral cycle in the two most recent European Union members (Bulgaria and Romania). Both countries are characterized by the perception of widespread corruption and a general distrust of politicians that are likely to hinder the development of strong ties between citizens and parties. We test the explanatory potential of both traditional and revisionist theories of partisanship, suggesting that perceptions of corruption should be treated as equal to evaluations of actual performance. The statistical analysis of comparative study of electoral systems survey data emphasizes the salience of party performance evaluations for party loyalty. Corruption perceptions are significant predictors of loyalty in the Bulgarian case. Voters in both countries assess critically the performance of their preferred party whether it was part of the government or in opposition. A significant difference arises between government and opposition voters with regard to the predictive potential of identification conceptualized as closeness to a party.

INTRODUCTION: A proper model analysis forms a vital part of the orthodontic diagnosis process, but it remains a time-consuming procedure. In day-to-day practice, many orthodontists assess the models subjectively, without applying analytical tests, due to the time it takes to do proper model analysis.1,2 Plaster dental models have long been the gold standard for orthodontic study model analysis and to calculate the Bolton index for tooth size disproportions, as well as intra-arch space discrepancies.3,4 Vernier callipers or needle pointed dividers are traditionally used to perform measurements on dental models.5 More recently digital orthodontic study models that are computer-based have been developed and have the potential to replace the traditional plaster orthodontic models.6 AIMS AND OBJECTIVES: The aim of this study was to do model analysis on one hundred orthodontic cases by making use of three different measuring tools. The objective was to see if a difference exists with regards to the measurements produced by the three different instruments and to compare the instruments with each other. MATERIAL AND METHODS: Three different instruments were used to measure Ave values on one hundred orthodontic study models. The three instruments included a Boley Gauge, Digital Vernier Calliper and Carestream 3600 scanner with accompanying software. The five values measured on the study models were: maxillary intercanine width, maxillary intermolar width, mesio-distal width of tooth 11, mesio-distal width of tooth 46 and mesio-distal width of tooth 41. RESULTS: The statistical analysis performed showed that the difference in measurements produced by the three instruments were not statistically significant for the inter-molar width (p = 0.849), intercanine width (p = 0.657), mesio-distal width of tooth 11 (p = 0.178) and mesio-distal width of tooth 41 (p = 0.240 The difference in measurements for the mesio-distal width of tooth 46 were statistically significant (p<0.01). However no clinically significant difference was found when the measurements produced by the three instruments were compared. CONCLUSIONS: All three of the instruments produced accurate measurements and can be used confidently when doing a comprehensive study model analysis for orthodontic diagnosis and treatment planning. The values produced were similar for all three instruments with insignificant differences between the three.

ABSTRACT Introduction Superior adhesive strength in luting agents is of paramount significance in fixed partial denture success. In this in vitro study five cements were tested for retentive qualities, using both lathe-cut and hand-prepared specimens. Materials and methods A total of 104 freshly extracted tooth specimens were prepared. Seventy of them were lathe-cut and 30 specimens were hand-prepared to simulate clinical conditions. Five different cements were tested, which included a compomer, a composite, a zinc phosphate, and 2 glass-ionomer luting cements. Of the 5, 2 trial cements were indigenously developed by Sree Chitra Tirunal Institute for Medical Sciences and Technology (SCTIMST), Trivandrum, India – a glassionomer cement (Chitra GIC) and a chemical-cure composite (Chitra CCC). All cements were compared within each group and between groups (lathe-prepared and hand-prepared). Results GC Fuji 1 (GC America) exhibited superior retentive strengths in both lathe-cut and hand-prepared specimens, whereas the compomer cement displayed the lowest values when tested. In lathe-cut specimens, statistical analysis showed no significant difference between GC Fuji 1 and indigenously developed Chitra CCC. Conclusion Both Chitra CCC and GC Fuji 1 have comparable strengths in lathe-cut samples, making Chitra CCC a potential luting agent. Statistical analysis reveals that all cements, except GC Fuji 1, exhibited a significant decrease in strength due to the change in design uniformity. The chemical bonding of GC Fuji 1 proves to be quite strong irrespective of shape and precision of the tooth crown. Clinical significance The indigenously developed Chitra GIC and Chitra CCC showed promising results to be used as a potential luting agent.

Purpose The aim of this study was to collect auditory-perceptual data on established symptom categories of dysarthria from typically developing children between 3 and 9 years of age, for the purpose of creating age norms for dysarthria assessment. Method One hundred forty-four typically developing children (3;0–9;11 [years;months], 72 girls and 72 boys) participated. We used a computer-based game specifically designed for this study to elicit sentence repetitions and spontaneous speech samples. Speech recordings were analyzed using the auditory-perceptual criteria of the Bogenhausen Dysarthria Scales, a standardized German assessment tool for dysarthria in adults. The Bogenhausen Dysarthria Scales (scales and features) cover clinically relevant dimensions of speech and allow for an evaluation of well-established symptom categories of dysarthria. Results The typically developing children exhibited a number of speech characteristics overlapping with established symptom categories of dysarthria (e.g., breathy voice, frequent inspirations, reduced articulatory precision, decreased articulation rate). Substantial progress was observed between 3 and 9 years of age, but with different developmental trajectories across different dimensions. In several areas (e.g., respiration, voice quality), 9-year-olds still presented with salient developmental speech characteristics, while in other dimensions (e.g., prosodic modulation), features typically associated with dysarthria occurred only exceptionally, even in the 3-year-olds. Conclusions The acquisition of speech motor functions is a prolonged process not yet completed with 9 years. Various developmental influences (e.g., anatomic–physiological changes) shape children's speech specifically. Our findings are a first step toward establishing auditory-perceptual norms for dysarthria in children of kindergarten and elementary school age.
