    The COVID-19 pandemic affected numerous learners around the world including Nepalese school children. These children experienced educational disruption arising from long school closures. Among other various educational models practiced during the COVID-19 pandemic to minimise such disruption, the use of ICT in education played an instrumental role. While a limited number of studies explore the use of technology during the pandemic in Nepalese secondary schools, none have yet explored in any depth how ICT was used and what affordances, i.e. action potentials of ICT, teachers perceived and acted upon. This study uses activity theory and the theory of affordances as a conceptual and methodological framework to explore the use of ICT in education during the COVID-19 pandemic in secondary schools and whether emerging affordances were acted upon by secondary school teachers. Remote classroom observations, focus groups and interviews with a variety of stakeholders were analysed using an activity theory-inspired coding scheme. The analysis indicates that a range of different educational practices such as Tole education, online teaching and learning among others were implemented during the COVID-19 crisis situation. Tole education is a neighbourhood-based approach that gathers children in a central location at the designated place (Tole) and holds regular learning sessions where pupils gather in small groups. Issues such as technological breakdowns, a shortage of good quality internet access at home, lack of engagement on the part of pupils, limited digital skills of teachers hindered the success of teaching during the pandemic. However, in attempts to resolve these issues, educational stakeholders such as teachers engaged with new initiatives. Consequently, educational and technological affordances emerged. Analysis of these emerging issues and affordances sheds light on issues and concerns pertaining to educational disruption in crisis situations and aids the framing of educational policies in such contexts

    Introduction:  Gestational trophoblastic diseases (GTD) include a spectrum of pregnancy-related diseases caused by abnormal proliferation of the placenta .  The main aim of this study to study the Correlation of ultrasound imaging with histopathological findings in gestational trophoblastic disease. Method: This is the retrospective study consisting of 155 sonographically diagnosed cases of GTD collected for three years 2016-2019. These patients were evaluated by transabdominal sonography. All these patients underwent Evacuation of product of conception (POC) and samples were subsequently sent for histopathological examination Their histopathological reports were followed up. The Correlation between USG and histopathological findings in GTD was studied. Result :  Among these 155 sonographically diagnosed cases of GTD 141 (91.0%) were  histologically confirmed GTD,  14 (9.0%) were  non-molar miscarriages on histological examination. In 141 cases of histologically confirmed GTD, 110 (71.0 %) were partial mole, 15 (9.7%) complete mole, 12 (7.7%) invasive mole and 3 (1.9 %) persistent mole, 1(0.6%) was choriocarcinoma. Conclusion :  The diagnostic accuracy of ultrasound to be 90% in the diagnosis of GTD, increasing its reliability. Thus ultrasound seems to be an initial modality of choice in the workup of every woman suspected of having GTD

    Mixed-Methods Research: A Discussion on its Types, Challenges, and Criticisms

    The article positions mixed-method research (MMR) as a principled complementary research method to the traditional quantitative and qualitative research approaches. By situating MMR in an analysis of some of the common research paradigms, the article presents it as a natural choice in order to complement and cater to the increasingly complex needs of contemporary researchers. It proffers MMR as a flexible and adaptive conceptual framework for designing and conducting mixed methods research in a simplified manner. By explaining fundamental principles and major theoretical tenets of a mixed-methods approach, which involves both quantitative and qualitative data collection in response to research questions, it elucidates several benefits of adopting MMR since it integrates post-positivism as well as interpretivism frameworks. There is abundant literature around this research design aiming to provide researchers an understanding of the approach. Yet there is limited literature that provides illustrative guidance to research novices in comprehending mixed methods, understanding reasons for choosing it, and selecting an appropriate mixed methods design. Based on an analysis of some notable works in the field, this article provides an overview of mixed methods designs, discusses its main types, and explains challenges one can potentially encounter when in using them with a view to assisting early career researchers in particular and other researchers in general

    Introductions: A rupture of the Anterior Cruciate Ligament (ACL) is the most common ligament injury resulting in instability of the knee which can cause secondary articular injury and early osteoarthritis (OA). Aim of this study was to evaluate the short term outcomes of ACL reconstruction using Bone Patellar Tendon Bone Auto Graft (BPTB) auto graft and factors that might contribute to poor results. Methods: Patients with Anterior Cruciate Ligament injury during the period of July 2013 to May 2014 were enrolled to observe the outcome of the ACL reconstruction using BPTB without arthroscopy. Lysholm Knee Scoring Scale was used to determine the clinical outcome. Outcome parameters were evaluated using Statistical Package for Social Science Version 20 (SPSS). Results: Total 30 normal or near normal function outcome of knee was reported in 29 (97%) patients after ACL reconstruction using BPTB without arthroscopy. There was no failure of grafts. Good static knee stability achieved with increased patient’s satisfaction. Lysholm Score was excellent in 27 (90%) and good in 3 (10 %) cases. Anterior knee pain persisted in 6 cases (20%). Conclusions: Excellent functional outcome with BPTB auto graft in Anterior Cruciate Ligament injury was achieved. Keywords: ACL reconstruction, bone-patellar tendon-bone auto graft, clinical outcom
