Background: As the coronavirus disease 2019 (COVID-19) pandemic spreads globally, hospitals are rushing to adapt their facilities, which were not designed to deal with infections adequately. Here, we present the management of a suspected COVID-19 patient. Case: A 66-year-old man with a recent travel history, infective symptoms, and chest X-ray was presented to our hospital. Considering his septic condition, we decided to perform an emergency surgery. The patient was given supplemental oxygen through a face mask and transported to an operating theatre on a plastic-covered trolley. An experienced anesthetist performed rapid sequence intubation using a video laryngoscope. Due to the initial presentation of respiratory distress, the patient remained intubated after surgery to avoid re-intubation. Precautions against droplet, contact, and airborne infection were instituted. Conclusions: Our objective was to facilitate surgical management of patients with known or suspected COVID-19 while minimizing the risk of nosocomial transmission to healthcare workers and other patients.

Collaborative Digital Storytelling-based Task for EFL Writing Instruction : Outcomes and Perceptions

Yek Amin Azis,Husnawadi 아시아영어교육학회 2020 The Journal of Asia TEFL Vol.17 No.2

Despite a myriad of studies documenting the educational benefits of digital storytelling (DST) on EFL learners’ language mastery, the majority of the research is not grounded in the theory of L2 instruction, say task based language teaching (TBLT). To fill this void, this action research involving 28 students investigated the efficacy of collaborative DST-based task in an Indonesian EFL writing classroom. Anchored in collaborative TBLT methodology instruction of Willis (1996) that met a set of task criteria coined by Ellis (2009), this study aimed to unveil the effect of collaborative DST-based task on the students’ writing skills; how the students perceived the use of the learning approach; and the challenges they encountered. The statistical evidence indicates that there was a significant difference on the students’ pre- and post-writing scores, which indicates that the use of collaborative DST-based task significantly improved students’ writing skills. The writing students perceived that the learning design could promote their English Language skills Development, engagement, motivation, and interpersonal relation. Another finding revealed that the students found the technological and pedagogical circumstances were their challenges. This study offers implications and recommendations for future research and practices for marrying TBLT and technology in ELT classrooms.

Poster Session : PS 0473 ; Nephrology ; A Case of Glomerular Hematuria and Spontaneous Intramural Small Bowel Hematoma in a Patient on Warfarin

( Jacklyn Yek ),( Lionel Cheng ),( Fazlur Jauferally ),( Chiara Chong ) 대한내과학회 2014 대한내과학회 추계학술대회 Vol.2014 No.1

Background: Over-warfarinisation can present in the elderly with varied clinical presentations. Retrospective examination of each patient`s clinical course can highlight key learning values. We report a case of warfarin-related nephropathy (WRN) and spontaneous intramural small bowel hematoma (SISBH) in an elderly patient on warfarin therapy. Methods: An 81-year-old Chinese male on long-term warfarin therapy for atrial fi brillation presents to the emergency department (ED) with one-week of persistent dysuria, three-days of ‘smoky-brown’ hematuria, fever, vomiting and supra-pubic tenderness. Prior to ED presentation, he had been prescribed a course of antibiotics with no symptomatic relief. The subsequent clinical course was suggestive of progressive intestinal obstruction. Results: Unenhanced Computed Tomography (CT) of the abdomen revealed hyperdense mural thickening, mainly of the jejunal loops, in keeping with SISBH. Work-up of hematuria was suggestive of a glomerular origin. Follow-up investigations revealed supra- therapeutic INR that upon correction led to spontaneous resolution of symptoms. Patient was discharged well a week later. Conclusions: Spontaneous resolution of WRN and SISBH with correction of coagulopathy highlights the importance of clinching the diagnosis to limit the progression of complications. In the clinical situation of acute kidney injury, unenhanced CT is helpful to detect and prognosticate the severity of SISBH. Supportive management and avoidance of nephrotoxins is suffi cient in the management of WRN.

이 연구의 목적은 시내 면세점을 방문한 해외여행 예정 내국인을 대상으로 시내 면세점에 대한 인식을 조사하는 것이다. 구체적으로, 해외여행 예정자가 인지하는 면세점 비주얼머천 다이징(visual merchandising: VMD) 구성요인의 어떠한 속성이 쾌락적 가치 및 실용적 가치에 영향을 미치는지 고찰하고, 쾌락적 가치 및 실용적 가치요인이 쇼핑 만족도를 유발시키는 관계를 분석하고자 한다. 연구 모델은 이전의 연구를 기반으로 설계되었다. 설문 조사는 무작위로 부산 시내 면세점을 방문한 개인에게 분배하였고, 329개 고객의 데이터는 구조방정식 모델링 분석을 사용하여 분석 하였다. 연구결과 면세점 비주얼머천다이징 구성요인 즉, 윈도우/상품진열, 레이아웃/동선구조, 크리에이티브/최신 트랜드 코디네이션, 가격과 프로모션 간판은 쾌락적 가치에 긍정적인 영향관계가 있었고, 크리에이티브/최신 트랜드 코디네이션, 가격과 프로모션 간판은 실용적 가치에 긍정적인 영향관계가 있었다. 그리고 쾌락적가치 및 실용적 가치요인과 쇼핑 만족도사이의 영향관계를 확인 하였다. 이러한 연구 결과를 바탕으로 시내면세점을 방문하는 잠재방문객 비율을 높이기 위해 VMD 구성요인에 대한 실무적 시사점을 제시하였다. The purpose of this study is to examine recognition on duty-free shops with future overseas travelers who have visited duty-free shops in the city. Specifically, authors investigated which factors of duty-free shops’ VMD influence hedonic value and utilitarian value and also analyzed whether hedonic value and utilitarian value induce shopping satisfaction or not. The model designed in this study is based on previous research. Questionnaires were distributed to individuals that had visited duty-free shops in Busan randomly, and 329 customer data were used for structural equation modeling analysis. According to the study results, duty-free shops’ VMD factors, window/merchandise display, layout/organization, creative/inspirational coordination, and price and promotion signage, have positive correlation with hedonic value, and creative/inspirational coordination and price and promotion signage have positive correlation with utilitarian value. Also, both hedonic value and utilitarian value have significant impact on shopping satisfaction. Based upon the empirical results, the present study offers useful implications for the VMD components from a practical perspective.

Background Our objective was to compare the complication rates of two common breast reconstruction techniques performed at our hospital and the cost-effectiveness for each test group. Methods All patients who underwent deep inferior epigastric perforator (DIEP) flap and transverse rectus abdominis myocutaneous (TRAM) flap by the same surgeon were selected and matched according to age and mastectomy with or without axillary clearance. Patients from each resultant group were selected, with the patients matched chronologically. The remainder were matched for by co-morbidities. Sixteen patients who underwent immediate breast reconstruction with pedicled TRAM flaps and 16 patients with DIEP flaps from 1999to 2006 were accrued. The average total hospitalisation cost, length of hospitalisation, and complications in the 2 year duration after surgery for each group were compared. Results Complications arising from both the pedicled TRAM flaps and DIEP flaps included fat necrosis (TRAM, 3/16; DIEP, 4/16) and other minor complications (TRAM, 3/16; DIEP, 1/16). The mean hospital stay was 7.13 days (range, 4 to 12 days) for the pedicled TRAM group and 7.56 (range, 5 to 10 days) for the DIEP group. Neither the difference in complication rates nor in hospital stay duration were statistically significant. The total hospitalisation cost for the DIEP group was significantly higher than that of the pedicled TRAM group (P<0.001). Conclusions Based on our study, the pedicled TRAM flap remains a cost-effective technique in breast reconstruction when compared to the newer, more expensive and tedious DIEP flap
