Social media in undergraduate medical education: A systematic review.

INTRODUCTION: There are over 3.81 billion worldwide active social media (SoMe) users. SoMe are ubiquitous in medical education, with roles across undergraduate programmes, including professionalism, blended learning, well being and mentoring. Previous systematic reviews took place before recent explosions in SoMe popularity and revealed a paucity of high-quality empirical studies assessing its effectiveness in medical education. This review aimed to synthesise evidence regarding SoMe interventions in undergraduate medical education, to identify features associated with positive and negative outcomes. METHODS: Authors searched 31 key terms through seven databases, in addition to references, citation and hand searching, between 16 June and 16 July 2020. Studies describing SoMe interventions and research on exposure to existing SoMe were included. Title, abstract and full paper screening were undertaken independently by two reviewers. Included papers were assessed for methodological quality using the Medical Education Research Study Quality Instrument (MERSQI) and/or the Standards for Reporting Qualitative Research (SRQR) instrument. Extracted data were synthesised using narrative synthesis. RESULTS: 112 studies from 26 countries met inclusion criteria. Methodological quality of included studies had not significantly improved since 2013. Engagement and satisfaction with SoMe platforms in medical education are described. Students felt SoMe flattened hierarchies and improved communication with educators. SoMe use was associated with improvement in objective knowledge assessment scores and self-reported clinical and professional performance, however evidence for long term knowledge retention was limited. SoMe use was occasionally linked to adverse impacts upon mental and physical health. Professionalism was heavily investigated and considered important, though generally negative correlations between SoMe use and medical professionalism may exist. CONCLUSIONS: Social media is enjoyable for students who may improve short term knowledge retention and can aid communication between learners and educators. However, higher-quality study is required to identify longer-term impact upon knowledge and skills, provide clarification on professionalism standards and protect against harms

A Fault Clearance and Restoration Approach for MMC-Based MTDC Grid

With the growth in continuous energy demand, high-voltage Multi-Terminal DC (MTDC) systems are technically and economically feasible to transmit bulk power and integrate additional energy sources. However, the high vulnerability of the MTDC systems to DC faults, especially pole-to-pole (P2P) faults, is technically challenging. The development of DC fault ride-through techniques such as DC circuit breakers is still challenging due to their high cost and complex operation. This paper presents the DC fault clearance and isolation method for an MMC-based MTDC grid without adopting the high-cost DC circuit breakers. Besides, a restoration sequence is proposed to re-energize the DC grid upon clearing the fault. An MMC-based four-terminal DC grid is implemented in a Control-Hardware-in-Loop (CHIL) environment based on Xilinx Virtex-7 FPGAs and Real-Time Digital Simulator (RTDS). The RTDS results show that the MTDC system satisfactorily rides through DC faults and can safely recover after DC faults

The pattern of social media use and its association with academic performance among medical students

Item does not contain fulltextBACKGROUND: There are concerns that the use of social media (SM) among medical students could affect academic performance. The objectives of the study were to investigate the pattern and reasons for SM use and their association with academic performance. METHODS: A stratified random sample, frequency distribution and comparison of categorical variables with Chi-square and Fisher exact tests were used. RESULTS: Of the 97% who responded, 98% used SM. The most popular were Whatsapp (87.8%), You tube (60.8%) and Twitter (51.8%) for general use; while You tube (83.5%), Whatsapp (35.5%) and Twitter (35.3%) for learning. For general use, there was a significant higher number of visits to You tube and Facebook among male students, while the reverse was true for Instagram and Path. Around 71% visited SM >4 times/day and 55% spent 1-4 hours/day. The main reasons for SM use were entertainment (95.8%), staying up-to-date with news (88.3%), and socializing (85.5%); for academic studies (40%). There was no significant association between Grade Point Average and the frequency of daily SM use or use during lectures. CONCLUSIONS: While almost all the students used SM, only a minority used them for academic purposes. SM use was not associated with academic performance
