Adapting Kwl Strategy for Teaching Science Practicals to Children with Special Needs for Effectives Learning

The learning of science is imperative for development in every society, and so it should not be limited to some persons. Therefore, these study sets out to use KWL strategy to adapt science teaching to the children with special needs for effective learning.The research design used in this study was the quazi experimental design specifically the pretest-posttest method. Three research questions guided the study. The sample of the study was made up of eight junior secondary one students from one public school in Lamingo, Jos plateau Nigeria. Intact class was used because there was no randomization. Base line data was collected from the class teacher on the students previous performance on the topic Classification of food. The researcher later taught same topic using KWL strategy for three weeks after which a test is given to collect data in form of scores. The data was analysed using percentage.The findings showed that KWL engaged students in the topic taught and also activated prior knowledge. KWL also enhanced good performance, thinking skill and promote curiosity.The researchers recommended that: teachers should ensure that appropriate activities be planned to take care of student needs; Government to ensure that all children have an equal right to education of any type

Epidemiology of lumbar disc herniations in adults with low back pain in Enugu, Nigeria

Background: Lumbar intervertebral disc herniation is used to describe a spectrum of anatomical abnormalities involving disc extension beyond the interspace. It follows a tear in the annulus fibrosus of the intervertebral disc. It is one of the most common causes of low back pain among adults. The study aims to assess the epidemiological pattern of lumbar disc herniations among adults with low back pain in Enugu urban.Methods: The study was a prospective study at National Orthopedic Hospital Enugu and Annunciation Specialist Hospital Enugu. Following ethical approval and written informed consent, patients who met the inclusion criteria were consecutively recruited. The MRI scans of the participants were viewed using DICOM® (Digital Imaging and Communications in Medicine) software on laptop computer. The data included the patients’ demographics, functional disability index for back pain, weight, height, the anatomical level(s) and site(s) of the herniated disc among other parameters.Results: A total of 81 subjects who met the inclusion criteria were included and analyzed using SPSS version 20.0. The mean age of the subjects is 52.99±13.13 years. The most common affected age group is 51-60 years (27.2%). Majority of the subjects (68; 84%) had multiple level herniations which usually includes L4 level(74; 91.4%).Conclusions: That multilevel lumbar disc herniation is far more common than single level herniation with a prevalence of 84% among adults with low back pain in Enugu urban. That, there is statistically significant association of lumbar disc herniation and increasing age

Assessment of complications following use of pneumatic tourniquet for elective orthopedic procedures at National Orthopedic Hospital, Enugu

Background: A pneumatic tourniquet is a constricting or compressing device with an inflatable cuff used to control venous or arterial circulation to an extremity for a period of time. Tourniquet safety is related to the cuff pressure and duration of application. The objective of this study was to determine the common complications that follow the use of pneumatic tourniquet in elective orthopaedic surgical procedures at National Orthopaedic Hospital Enugu.Methods: This was a prospective study over 18 month period (June 2014 – November 2015) at National Orthopaedic Hospital, Enugu. Following ethical approval and written informed consent, patients who met the inclusion criteria were consecutively recruited. The study was conducted using the ‘intelligent pneumatic tourniquet’ with single bladder reusable cylindrical cuff. The cuff pressure was determined in each case by addition of 100mmHg to the baseline systolic BP for the upper limbs and 150 mmHg to the baseline systolic BP for the lower limbs. The data collected included patients’ demographics, cuff pressure, cuff location, tourniquet duration and complication encountered among other parameters.Results: A total of 160 procedures in 152 patients were included and analyzed using SPSS version 20.0. The prevalence rate of 1.9% for nerve palsy, 1.3% for tourniquet pain, 1.9% for surgical site infection and 5.6% for pressure sore were found in the study. No other complication was encountered.Conclusions: From the results of this study, it is concluded that the use of pneumatic tourniquet under the prescribed conditions is associated with low prevalence of complications

Convalescent plasma in patients admitted to hospital with COVID-19 (RECOVERY): a randomised controlled, open-label, platform trial

SummaryBackground Azithromycin has been proposed as a treatment for COVID-19 on the basis of its immunomodulatoryactions. We aimed to evaluate the safety and efficacy of azithromycin in patients admitted to hospital with COVID-19.Methods In this randomised, controlled, open-label, adaptive platform trial (Randomised Evaluation of COVID-19Therapy [RECOVERY]), several possible treatments were compared with usual care in patients admitted to hospitalwith COVID-19 in the UK. The trial is underway at 176 hospitals in the UK. Eligible and consenting patients wererandomly allocated to either usual standard of care alone or usual standard of care plus azithromycin 500 mg once perday by mouth or intravenously for 10 days or until discharge (or allocation to one of the other RECOVERY treatmentgroups). Patients were assigned via web-based simple (unstratified) randomisation with allocation concealment andwere twice as likely to be randomly assigned to usual care than to any of the active treatment groups. Participants andlocal study staff were not masked to the allocated treatment, but all others involved in the trial were masked to theoutcome data during the trial. The primary outcome was 28-day all-cause mortality, assessed in the intention-to-treatpopulation. The trial is registered with ISRCTN, 50189673, and ClinicalTrials.gov, NCT04381936.Findings Between April 7 and Nov 27, 2020, of 16 442 patients enrolled in the RECOVERY trial, 9433 (57%) wereeligible and 7763 were included in the assessment of azithromycin. The mean age of these study participants was65·3 years (SD 15·7) and approximately a third were women (2944 [38%] of 7763). 2582 patients were randomlyallocated to receive azithromycin and 5181 patients were randomly allocated to usual care alone. Overall,561 (22%) patients allocated to azithromycin and 1162 (22%) patients allocated to usual care died within 28 days(rate ratio 0·97, 95% CI 0·87–1·07; p=0·50). No significant difference was seen in duration of hospital stay (median10 days [IQR 5 to >28] vs 11 days [5 to >28]) or the proportion of patients discharged from hospital alive within 28 days(rate ratio 1·04, 95% CI 0·98–1·10; p=0·19). Among those not on invasive mechanical ventilation at baseline, nosignificant difference was seen in the proportion meeting the composite endpoint of invasive mechanical ventilationor death (risk ratio 0·95, 95% CI 0·87–1·03; p=0·24).Interpretation In patients admitted to hospital with COVID-19, azithromycin did not improve survival or otherprespecified clinical outcomes. Azithromycin use in patients admitted to hospital with COVID-19 should be restrictedto patients in whom there is a clear antimicrobial indication

Personality, socioeconomic status, attitude, intention and risky driving behavior

Risky driving behavior (RDB) is one of the human factors contributing to the majority traffic injuries and crashes. This paper examines the influence of personality factors on RDB and the mediating role of intention and attitude in the relationship. The influence of different SES, personality, marital status, and gender characteristics on attitude, intention, and risky driving was also examined. A sample of 354 fully licensed Ghanaian drivers, including 278 males and 76 females, participated in the study at two times points separated by three months. The correlation results showed that unhealthy family relationship and negative emotions were positively associated with illegal speed-related behaviors, risky driving, and accident involvement. The results of a structural equation model suggested that personality variables significantly and positively influence intention and attitude toward speeding, with normlessness directly and positively influencing RBD. The mediation analysis shows that intention mediated the effects of personality variables on RBD. No significant mediating effect for attitude was found. The analysis of variance result shows that drivers with high socioeconomic status and personality had the high intention and attitude toward speeding and reported more RDB. Finally, drivers who had been divorced significantly reported more positive attitude toward speeding than the married and single group. Based on the results, the study concludes that, in accessing the effect of personality measures on RDB, it is important to include intention as a possible mediator for more accurate decision. Practical implications for managing different personalities and socioeconomic positions are also discussed

Investigating students’ perception towards the use of social media for computing education in Nigeria

Abstract This study examined the use of a social media platform — WhatsApp — by computer science students for learning computing education in the context of a Nigerian education institution. Nowadays, a large community of students in higher education institutions has embraced the WhatsApp platform for social interactions which makes it a useful tool in education. In this study, students formed three closed groups, and each group had a specific computing topic they discussed. Their discussions were in the form of posting questions, providing answers to questions, or expressing knowledge on the group topic. A questionnaire was used to collect data from the participants regarding their experiences. We conducted a descriptive analysis of the students’ learning outcomes. The results show that the use of social media contributes positively to students’ learning achievement, and they are motivated to acquire more knowledge about different computing topics
