Aim/Purpose: This study aims to explore whether instructors and educators should segment portions of instructional video that can be loaded and executed independently of other portions, and how long the segment portion of instructional video should be to effectively influence students’ learning, perception, and interaction. Background: Instructional videos are widely used in higher education for pedagogy purposes, and students expect their face-to-face and online courses to include video for effective instructional and learning outcomes. The literature indicates that researchers suggested that segmented video might assist learning and reduce cognitive burden; however, empirical research does not provide sufficient guidance about how to do it. Methodology: This mixed-methods study included quantitative data from an online experiment, followed by qualitative data from focus groups to help explain and expand on the quantitative findings. This study compared a 14-minute instructional video with the same content split into three segments, ranging from four to five minutes in length, to explore how segmenting affects students’ learning and how students perceive and interact with the video. The quantitative portion of the study used an experimental design with random assignment to control and experimental groups. Participants were randomly assigned by Qualtrics to one of two conditions where they watched either a single long (14-minute) video (the control group) or the same content split into three video segments (the experimental group). Participants in both groups were asked to watch the video(s), take a content knowledge quiz, and respond to an opinion questionnaire. The qualitative portion of the study consisted of focus groups where participants were asked to reflect on their overall perceptions of using online instructional video. Contribution: This study contributes to the literature knowledge on how students interact with instructional video and how, and if, longer instructional videos should be divided into shorter segments. Findings: Results from this study indicated that there is no significant difference between the Long Video Group (control group) and the Segmented Video Group (experimental group) on measures of learning, interaction with or perceptions of the video. However, participants who engaged in multitasking activities other than texting performed worse on the learning measure. The focus group participants described a variety of behaviors and preferences for watching the instructional video but expressed a preference for videos that were about 20 minutes long. Recommendations for Practitioners: For the purpose of building declarative knowledge, the number and length of instructional video segments may be less important than the other instructional materials and strategies instructors and educators provide to support students’ interaction with the instructional video. Recommendation for Researchers: The qualitative findings suggest that while preferred instructional video length may differ based on context, a 20-minute instructional video may be preferred, or at least accepted, in a typical academic setting, though this possibility needs further study. Impact on Society: Results from this study may help instructors and educators to create high quality instructional video content by acknowledging that decisions about instructional video length and segmenting require professional discretion rather than arbitrary rules regarding video length. Future Research: Future researchers and practitioners can further evaluate and enhance the importance and design of instructional videos for pedagogical purposes, and additional research is needed before instructors, educators, and the educational field can accept the thought that any video over five or six minutes is considered too long for students’ attention span.

This prospective double blind comparative study was designed to compare the effect of Dutasteride on the perioperative blood loss in Transurethral Resection of Prostate (TURP).Sixty patients with BPH underwent TURP were divided into 2 groups. Patients belong to the group B (Control) and group A (Experimental). Experimental group patients were given Cap. A (dutasteride 0.5 mg) before two weeks of TURP and group B (control) were given Cap. B (placebo). Postoperative comparison between two groups showed that there were no significant difference between the weight of resected prostatic tissue (control =22.41±6.83 gm, and experimental = 25.38±7.22 gm; p=0.107). Postoperative hemoglobin level of both group (Control group = 10.78±0.64 gm/dL and experimental group = 10.83±.51 gm/dL) revealed no significant difference (p=0.774). The mean hemoglobin loss per gram of prostate tissue in both groups (control = 1.81±0.81 gm/gm and experimental = 1.79±0.88 gm/gm) did not show any statistical difference (p=0.938). In this the study it was found that if the BPH patients are subjected with dutasteride 0.5mg before 2 weeks of TURP, bleeding decrease slightly (Control group = 20.35±7.99 ml/gm and Experimental groups = 17.41±7.70 ml/gm). However, these data of bleeding loss did not show any statistical significance. Bangladesh Journal of Urology, Vol. 22, No. 2, July 2019 p.177-181

The purpose of this non-random retrospective cohort study was to evaluate the impact of prophylactic antibiotic on early outcomes including postoperative pain, swelling, bleeding and cyanosis in patients undergoing dental implant placement before prosthetic loading. Seventy-five patients (45 males, 30 females) whose dental implant placement were completed, included to the study. Patients used prophylactic antibiotics were defined as the experimental group and those who did not, were defined as the control group. The experimental group received 2 g amoxicillin + clavulanic acid 1 h preoperatively and 1 g amoxicillin + clavulanic acid twice a day for 5 days postoperatively while the control group had received no prophylactic antibiotic therapy perioperatively. Data on pain, swelling, bleeding, cyanosis, flap dehiscence, suppuration and implant failure were analyzed on postoperative days 2, 7, and 14 and week 12. No statistically significant difference was detected between the two groups with regard to pain and swelling on postoperative days 2, 7, and 14 and week 12 ( p >0.05), while the severity of pain and swelling were greater on day 2 compared to day 7 and 14 and week 12 in both groups ( p =0.001 and p <0.05, respectively). Similarly, no significant difference was found between the two groups with regard to postoperative bleeding and cyanosis. Although flap dehiscence was more severe on day 7 in the experimental group, no significant difference was found between the two groups with regard to the percentage of flap dehiscence assessed at other time points. Within limitations of the study, it has been demonstrated that antibiotic use has no effect on implant failure rates in dental implant surgery with a limited number of implants. We conclude that perioperative antibiotic use may not be required in straightforward implant placement procedures. Further randomized control clinical studies with higher numbers of patients and implants are needed to substantiate our findings.

          Peer teaching is a strategy that allows the students to teach the new content to each other, and they must be accurately guided by instructors.     The researcher proposes that the use of students peer teaching  may promote students' achievement  and ensure the engagement of all the students in the learning process. Therefore, the researcher employs it as a teaching method aiming at investigating its  effect on Iraqi EFL students' achievement in the course of Library and Research Work .      The study hypothesizes that there is no significant difference between the students' achievement who are taught library and research work by students peer teaching  and that of the students taught by the traditional way. The experimental design of the study is Parallel Groups, Random Assignment, posttest. Each group consists of 35 students, chosen randomly from the Third Year Students at the Department of English in the College of Basic Education. Both groups were matched in terms of their age and parents' education. The experiment was fulfilled in the first course for 15 weeks during the academic year 2016-2017.       The same materials were presented to both groups. This included   units from Writing Research Paper by Lester D. . Post-test was constructed and exposed  The t-test for  independent samples was used to analyze the results and it is found out that there is a statistical difference between the two groups in their achievement because the calculated t- value 2.635 is bigger than the tabulated t- value which is 2.000, and also shown the superiority of the experimental group. The results indicate that the experimental group, who was taught Library and Research Work by peer teaching   was better than the control group, who was taught according to the traditional way. So, the null hypothesis is rejected. Finally, some recommendations and suggestions are presented in the light of the study findings. to a jury of experts to verify its validity and it was administered to both groups.

Topicality: The result of surgical treatment depends largely on the chosen method of management of the postoperative period, the main purpose of which is to reduce the effects of surgical trauma. Despite the wide variety of drugs for local and systemic use, the question of pharmacotherapy of the operated sinus remains open to this day. The main properties that a modern drug should possess are safety and high clinical efficacy. Aim: to study the clinical efficacy of topical application of a complex preparation based on a saline solution containing sodium hyaluronate and dexpanthenol in patients with chronic sinusitis after functional endoscopic sinus surgery (FESS). Materials and Methods: Clinical and laboratory studies were conducted on 47 patients with chronic rhinosinusitis who underwent surgery using the FESS technique. Patients were divided into 2 groups according to the principle of the postoperative period. Patients of research group (n=21), except for traditional therapy, was used locally NASOMER (a preparation based on a water-salt solution containing sodium hyaluronate and dexpanthenol); to the control group (n=26) patients entered, in the postoperative period received traditional therapy. Traditional therapy included a toilet of the nasal cavity, the use of short-course topical decongestants, irrigation of the nasal cavity with water-salt solutions. Criteria of clinical effectiveness: data of endoscopy of the nasal cavity, rhinomanometry, activity of the mucociliary transport system. The effectiveness of functional research methods in the postoperative period was determined on the 7th and 14th day of treatment. Results: On the 3rd day of the study, an increase in the swelling of the nasal cavity was observed in patients of both clinical groups, correlated with difficulty in nasal breathing. On the 7th day, a decrease in edema was observed in patients of both groups, but in the experimental group, the index of nasal breathing, according to rhinomanometry, was significantly (p<0.05) different from the control group, and was respectively 1.54±0.14 and 2.04±0.19 kPa/l*s. On the 14th day of the study, no significant difference was observed between these indicators. When studying the activity of the ciliated epithelium of the mucous membrane of the nasal cavity, it was proved that patients of the experimental group on day 7 after surgery showed a statistically significant difference in this indicator compared to the control group (17.8±1.0 and 22.7±2.1 min. respectively). Conclusions: The use of NASOMER after surgical intervention in patients with chronic rhinosinusitis contributes to more effective treatment compared with traditional therapy, as evidenced by the rapid recovery of the main functional parameters according to active posterior rhinomanometry and mucociliary clearance. Based on the results of the studies performed, the use of NASOMER for pharmacotherapy in the postoperative period is recommended for patients who have undergone rhinosurgical interventions with the aim of reducing the period of postoperative rehabilitation as an effective anti-inflammatory and wound-healing agent.

Aims: Investigation thyroid dysfunction and autoimmunity in pregnant women with gestational diabetes mellitus. Background: This article was written to evaluate the thyroid function and anti-thyroid peroxidase (anti- TPO) antibodies in pregnant women with gestational diabetes mellitus (GDM). Method: A total of 252 women with GDM and 252 healthy pregnant women were enrolled. Thyroid tests, including TSH, FreeT3, Free T4, and anti-TPO were performed for all women at 24–28 weeks of gestation. Data analysis was then carried out using SPSS ver. 22. Result: There was a significant difference between the experimental group (38.4%) and the control group (14.06%) in terms of the prevalence of subclinical hypothyroidism (p= 0.016). The frequency of anti-TPO was higher in the experimental group than the control group and positive anti-TPO was observed in 18.6% of women with GDM and 10.3% of healthy pregnant women (P= 0.008). Conclusion: Thyroid disorders are observed in pregnant women with GDM more frequently than healthy individuals and it may be thus reasonable to perform thyroid tests routinely.
