Abstract Dam construction is one of the most popular solutions for managing water resources. In recent years, changes in patterns of regional seismicity associated with large impoundment dams have raised concerns among environmentalists. In this study, five large dams located in Iran were studied from this perspective. The Gutenberg-Richter, linear regression and T-test were used to examine the seismic changes in the radius of 100 km of each of the dams during a twenty-five-year period before and after the construction of the dams. The results revealed that the seismicity level and relative density of large and small earthquakes in three of these dams have increased after dam construction. A significant difference between the magnitude of earthquakes, as well as the number of earthquakes before and after the construction of dams in the region, was recognized. However, the results of the T-test statistical analysis indicated that the mean depth of the earthquakes and their distance from the dams before and after construction have not changed significantly. Overall, these results indicated that the construction of large impoundment dams has been associated with some changes in patterns of regional seismicity. The findings would guide researchers to further investigate the type of impacts that dam construction may have on seismicity patterns.

<b><i>Objectives:</i></b> This study aimed to determine the oral morphine equivalents (OMEs) prescribed and refill rates following hysterectomy and hysteroscopy in the setting of opioid prescribing practice changes in 2 states. <b><i>Design:</i></b> This is a retrospective cohort analysis consisting of 2,916 patients undergoing hysterectomy or hysteroscopy between July 2016 and September 2019 at 2 affiliated academic hospitals in states that underwent legislative changes in opioid prescribing in 2018. <b><i>Methods:</i></b> Participants were identified using the Current Procedural Terminology procedure codes in Arizona and Florida. Hysterectomy was chosen as the most invasive gynecologic procedure, while hysteroscopy was chosen as the least invasive. Medical records were abstracted to find opioid prescriptions from 90 days before surgery to 30 days after discharge. Patients with opioid use between 90 and 7 days before surgery were excluded. Prescriptions were converted to OMEs and were calculated per quarter year. Statistical analysis included Wilcoxon rank sum <i>t</i> tests for OMEs and χ<sup>2</sup> <i>t</i> tests for refill rates. Interrupted time-series analysis was used to determine significant change in OMEs before and after legislative change. Statistical analysis was performed using SAS version 9.4 (SAS Institute, Cary, NC, USA). <b><i>Results:</i></b> In Arizona, 1,067 hysterectomies were performed; 459 (43%) vaginal, 561 (52.6%) laparoscopic/robotic, and 47 (4.4%) abdominal. There were 530 hysteroscopies. Overall median OMEs decreased from 225 prior to July 2018 to 75 after July 2018 (<i>p</i> &#x3c; 0.0001). The opioid refill rate remained unchanged at 7.4% (<i>p</i> = 0.966). In Florida, there were 769 hysterectomies; 241 (31.3%) vaginal, 476 (61.9%) laparoscopic/robotic, and 52 (6.8%) abdominal. There were 549 hysteroscopies. Overall median OMEs decreased from 150 prior to July 2018 to 0 after July 2018 (<i>p</i> &#x3c; 0.0001). The opioid refill rate was similar (7.8% before July 2018 and 7.3% after July 2018; <i>p</i> = 0.739). <b><i>Limitations:</i></b> Limitations include involvement of a single hospital institution with a total of 10 fellowship-trained surgeons and biases inherent to retrospective study design. <b><i>Conclusions:</i></b> Legislative and provider-led changes coincided with decreases in opioid prescribing after 2018 in both states without increasing rates of refills and showed actual data reflected in the medical record. Gynecologists must actively participate in safe prescribing practices to decrease opioid dependence and misuse.

<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>

Effect of  role playing macro methods on children's speaking ability in group B in Nurul Rohmah Bekasi. This research is motivated by the lack of ability to speak children. This is because the method used in the learning process is more likely to use conventional methods. The selection of methods to role playing macro so that children can be motivated and interested in learning and can stimulate the ability to speak children. The population in this study were all children of group B in kindergarten Nurul Rohmah while the study sample was B3 group 11 children for the experimental group and B1 group 11 children for the control group. Data collection techniques through test techniques, and observation. Data analysis techniques used were descriptive statistical analysis and nonparametric statistical analysis. Based on the results of the Wilcoxon test calculation, the calculated T value is 66 and T table 11 then the results obtained T count (66)> T table (11) H1 is accepted and Ho is rejected means that there is an effect of role playing macro  methods on children's speaking ability. Whereas the calculated Z value obtained is 2.93 and 1.645 table Z then the result of Z arithmetic (2.93)> Z table (1.645) H1 is accepted and Ho is rejected which means that there is an effect of role playing macro method on children's speaking ability. These results indicate that there is a change in the value of the child's speaking ability before and after getting learning based on the role playing macro method.

PURPOSE: To compare the efcacy between SO and salicylic acid SA in the treatment of plantar keratosis of diabetic patients. METHODS: Randomized, double-blind clinical trial, with 47 type 2 diabetic patients, both sexes and with plantar keratosis. Patients were randomized into 2 groups: G1 (n = 48; treated with 15% SO extract) and G2 (n = 46; treated with 10% AS). The feet were photographed before (D0) and after the treatment (D30) and keratosis areas were measured using the Image J software. For each patient, a lesion in each foot was analyzed. The results were expressed by median. In the statistical analysis, the Wilcoxin test was used to compare the lesion areas before and after treatments and the Mann-Whitney test was used to compare the regression of the lesion areas between the two groups. P <0.05 was adopted. RESULTS: G1 (D0 = 2 8.156 vs D30 = 2.226; p <0.0001) and G2 (D0 = 4.835 vs D30 = 2.059; p <0.0001) showed a difference between the areas (cm ) of the keratosis, 2 before and after the treatment. There was a difference in the regression of the areas (cm ) of keratosis, between G1 and G2, respectively (4.540 vs 1.171, p <0.0001). CONCLUSION: Symphytum ofcinale proved to be more effective than Salicylic Acid in the treatment of plantar keratosis in diabetic patients.
