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.

Purpose: Evaluate obstetrics and gynecology (OB/Gyn) residents’ current obstetric sonography knowledge, confidence, and psychomotor skills to provide clinical preceptors with a greater understanding of how to approach teaching sonography to residents. Methods: Ten OB/Gyn residents were assessed on their sonographic performance by measuring psychomotor skills and evaluating diagnostic accuracy of images. At the conclusion of the assessment, residents received feedback and completed a survey to establish their current confidence level in performing and interpreting sonograms. Results: Motion analysis revealed excessive transducer movements made by the residents when acquiring images, particularly in terms of angular movement. The median score on the assessment template was 33 out of 66 points (interquartile range, 26.75–42.5), where residents had difficulty acquiring all required criteria for first-trimester dating and biometry views/measurements, determining fetal situs, and identifying landmarks to ensure intended anatomy is visualized. Conclusions: Absence of formalized sonography training creates a need for clinical preceptors to teach basic anatomy/landmarks, transducer movements, and criteria for dating and biometry views/measurements. This poses a challenge for preceptors at high-volume sites; thus, high-fidelity simulation could be part of a solution. Simulation can provide residents with the opportunity to develop basic sonography skills outside of clinical, then refine and build upon those skills with preceptors.

<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>

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.

Our study aimed to analyze mental toughness and its relationship to sports performance. We reviewed 38 qualitative and quantitative international studies. We performed an in-depth investigation on mental toughness; we also focused on how to improve mental toughness. We hypothesized a significant difference in both genders, suggesting that coaches substantially impact mental toughness. We primarily concentrate on valid, real-time assessments and psychological training in elite sports athletes. Sport psychologists, mental trainers play an essential role in elite sports performance.  Results of related studies demonstrated that these age and gender-specific mental training sessions are effective in improving performance. There is an increasing need for computer-based interactive testing methods to analyze cognitive and psychomotor skills under pressure.

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.

Abstract: Chlorine is a green halogen-shaped halogen gas at normal temperature and serves as bleach, stain remover and disinfectant. Chlorine is now widely used for bleaching rice so that less quality rice looks like quality rice. Chlorine is very toxic and causes mucous membrane irritation, highly reactive and very powerful oxidizer. The purpose of this research was to determine the difference of chlorine level in chlorinated rice washed once, twice and 3 times. The sample in this study amounted to 11 samples calculated by replication formula. Each sample was treated 3 times, ie 1 washed once, 2 washed twice and washed 3 times. The samples then examined by iodometric titration method. Based on the results of the study using ANOVA test, 11 samples obtained the average value of chlorine after washed once amount of 0.0176%, after washed twice amount of 0.0111%, and after washed 3 times amount of 0.0052% with the value significance p = 0.03 (p <0.05) at 95% confidence level which means there was a significant difference between chlorine levels in chlorinated rice washed once, twice and 3 times.Abstrak: Klorin merupakan unsur halogen berbentuk gas berwarna kuning kehijauan pada suhu normal danberfungsi sebagai pemutih, penghilang noda maupun desinfektan. Klorin sekarang banyak digunakan untuk bahan pemutih beras agar beras yang kurang berkualitas tampak seperti beras berkualitas.

Introduction: The basic determinant of healthy behaviour—among other human behaviours—is the fact that it consistently affects health. Nowadays, health behaviour studies are considered to be an important method of measuring the health of a population. Objective: To assess the health behaviours and value-based health analysis of people aged 50+ who were hospitalized due to cardiovascular disease, depending on the selected descriptive variables. Materials and methods: The study was conducted between April 2018 and December 2018 among 411 subjects aged 50+ who were hospitalized due to cardiovascular disease at the Independent Public Health Care Unit in Sanok (Podkarpackie voivodship in Poland). The method used in the study was a diagnostic survey. The study used the authors’ survey questionnaire and two standardized tests: Inventory of Health-Related Behaviour (IHB) and List of Health Criteria (LHC). A statistical analysis was carried out in the R program, version 3.5.1. The obtained results were subjected to thorough statistical analysis using the following tests: Student’s t, Mann–Whitney U, ANOVA, Kruskal–Wallis, Fisher’s Least Significant Difference (LSD), Pearson, and Spearman. Results: The strongest correlation between health status and health behaviours (according to the IHB questionnaire) was in the area of ‘health practices’, while the lowest correlation was found in the areas of ‘correct eating habits’ and ‘preventive behaviours’. Based on the LHC questionnaire, the most important health criteria according to the subjects were ‘not feeling any physical ailments’; ‘having all body parts functional’; ‘feeling well’; ‘eating properly’; and ‘infrequent need of going to the doctor’. A positive correlation was found in the group of respondents where the ‘preventive health behaviours’ were more intense; herein, the more important criterion for the respondents was ‘eating properly’. Conclusions: Respondents aged 50+ and hospitalized for cardiovascular diseases indicated (based on the IHB questionnaire) that health behaviours in the area of ‘health practices’ had the strongest correlation with their health, while the lowest correlation was found in the areas of ‘correct eating habits’ and ‘preventive behaviours’. According to the respondents, the most important criteria determining health (according to the LHC questionnaire) included ’not feeling any physical ailments’; ‘having all body parts functional’; ‘feeling well’; ‘eating properly’; and ‘infrequent need of going to the doctor’. Based on the information collected from the respondents, it was found that the most important criteria determining health depended on selected descriptive variables, such as age, gender, place of residence, education, and marital status.

Introduction After extensive mediastinal dissection fails to achieve adequate intra-abdominal esophageal length, a Collis gastroplasty(CG) is recommended to decrease axial tension and reduce hiatal hernia recurrence. However, concerns exist about staple line leak, and long-term symptoms of heartburn and dysphagia due to the acid-producing neoesophagus which lacks peristaltic activity. This study aimed to assess long-term satisfaction and GERD-related quality of life after robotic fundoplication with CG (wedge fundectomy technique) and to compare outcomes to patients who underwent fundoplication without CG. Outcomes studied included patient satisfaction, resumption of proton pump inhibitors (PPI), length of surgery (LOS), hospital stay, and reintervention. Methods This was a single-center retrospective analysis of patients from January 2017 through December 2018 undergoing elective robotic hiatal hernia repair and fundoplication. 61 patients were contacted for follow-up, of which 20 responded. Of those 20 patients, 7 had a CG performed during surgery while 13 did not. There was no significant difference in size and type of hiatal hernias in the 2 groups. These patients agreed to give their feedback via a GERD health-related quality of life (GERD HRQL) questionnaire. Their medical records were reviewed for LOS, length of hospital stay (LOH), and reintervention needed. Statistical analysis was performed using SPSS v 25. Satisfaction and need for PPIs were compared between the treatment and control groups using the chi-square test of independence. Results Statistical analysis showed that satisfaction with outcome and PPI resumption was not significantly different between both groups ( P > .05). There was a significant difference in the average ranks between the 2 groups for the question on postoperative dysphagia on the follow-up GERD HRQL questionnaire, with the group with CG reporting no dysphagia. There were no significant differences in the average ranks between the 2 groups for the remaining 15 questions ( P > .05). The median LOS was longer in patients who had a CG compared to patients who did not (250 vs. 148 min) ( P = .01). The LOH stay was not significantly different ( P > .05) with a median length of stay of 2 days observed in both groups. There were no leaks in the Collis group and no reoperations, conversions, or blood transfusions needed in either group. Conclusion Collis gastroplasty is a safe option to utilize for short esophagus noted despite extensive mediastinal mobilization and does not adversely affect the LOH stay, need for reoperation, or patient long-term satisfaction.
