        A Study of the Effects of Transmedia Storytelling on Active Participation and Language Learning

        Lee Yun Joon Jason(Yun Joon Jason Lee) 영상영어교육학회 2022 영상영어교육 (STEM journal) Vol.23 No.2

        This study observed the following two purposes: (1) to investigate whether transmedia storytelling (TS) encourages beginner-level college students to actively participate in classwork, and (2) to determine whether TS is positively related to second language (L2) learning. The transmedia approach will help the students to gain more knowledge and information about the target language. Two beginners were invited to act as case studies to these ends. An American television series, The Good Place (Holland, 2018), was chosen. This study was conducted in three stages: (1) participant presentations on selected topics via TS, (2) first recall test (one week later, with notice), and (3) second recall test (two weeks later, without notice). On the first test, Participant A scored well on his selected topic, but his score dropped somewhat on Participant B’s topic. Participant B had a better score than Participant A on both topics. The second test was an error analysis. Participant A had minor errors on the TS-based topic but significant ones on the not-TS-based topic. Participant B had fewer errors than Participant A on both topics, and all his errors were minor. Both participants were involved in active participation. Pedagogical implications are discussed in the conclusion.

        Using Films in Second-Language Learning: Perspectives Through the Lens of Transmedia and Cultural Learning

        Lee Yun Joon Jason(Yun Joon Jason Lee) 영상영어교육학회 2022 영상영어교육 (STEM journal) Vol.23 No.4

        This study had two objectives: (1) to observe how the participants used a TV series to learn English and (2) to investigate to what extent they changed the way they used the TV series to learn English based on three activities or guidelines that a teacher gave for better learning. They were, first, that the centrality of the meaning (of the lexicon and of the pattern) is core in using TV series for L2 learning; second, how to learn conventional expressions; and third, that in using a language, language knowledge and world knowledge should be combined. For the analysis, the participants’ reports were used. For the first guideline, it was found that the participants primarily paid attention to understanding the utterances in the script. They performed poorly. In the second activity, the participants performed relatively well. In the third activity, when the participants were assisted, they were able to focus on patterns. After the activities, they realized that they could learn the importance of context and culture as well as conventional expressions. A pedagogical implication of these findings is that although TV series are expected to make learning enjoyable, language matters should take precedence.

        Cardiorenal Protection in Diabetic Kidney Disease

        Jason F. Lee,Ecaterina Berzan,Vikas S. Sridhar,Ayodele Odutayo,David Z.I. Cherney 대한내분비학회 2021 Endocrinology and metabolism Vol.36 No.2

        Over the last 5 years there have been many new developments in the management of diabetic kidney disease. Glucagon-like peptide-1 receptor agonists (GLP-1 RA) and sodium-glucose cotransporter-2 (SGLT2) inhibitors were initially used for glycemic control, but more recent studies have now shown that their benefits extend to cardiovascular and kidney outcomes. The recent additionof data on the novel mineralocorticoid receptor antagonist (MRA) gives us another approach to further decrease the residual risk ofdiabetic kidney disease progression. In this review we describe the mechanism of action, key studies, and possible adverse effects related to these three classes of medications. The management of type 2 diabetes now includes an increasing number of medicationsfor the management of comorbidities in a patient population at significant risk of cardiovascular disease and progression of chronickidney disease. It is from this perspective that we seek to outline the rationale for the sequential and/or combined use of SGLT2 inhibitors, GLP-1 RA and MRAs in patients with type 2 diabetes for heart and kidney protection.

        Decompression without Fusion for Low-Grade Degenerative Spondylolisthesis

        Jason Pui Yin Cheung,Prudence Wing Hang Cheung,Kenneth Man Chee Cheung,Keith Dip-Kei Luk 대한척추외과학회 2016 Asian Spine Journal Vol.10 No.1

        Study Design: Retrospective series. Purpose: Assess results of decompression-only surgery for low-grade degenerative spondylolisthesis with consideration of instability. Overview of Literature: There is no consensus on whether fusion or decompression-only surgery leads to better outcomes for patients with low-grade degenerative spondylolisthesis. Current trends support fusion but many studies are flawed due to over-generalization without consideration of radiological instability and their variable presentations and natural history. Methods: Patients with surgically treated degenerative spondylolisthesis from 1990–2013 were included. Clinical and radiological instability measures were included. Any residual or recurrence of symptoms, revision surgery performed and functional outcome scores including the numerical global rate of change scale, visual analogue scale, and modified Barthel index were measured. Followup periods for patients were divided into short-term (<5 years), mid-term (5–10 years) and long-term (>10 years). Results: A total of 64 patients were recruited. Mechanical low back pain was noted in 48 patients and most (85.4%) had relief of back pain postoperatively. Radiological instability was noted in 4 subjects by flexion-extension radiographs and 12 subjects with prone traction radiographs by increased disc height and reduction of olisthesis and slip angle. From the results of the short-term, midterm and long-term follow-up, reoperation only occurred within the first 5-year follow-up period. All functional scores improved from preoperative to postoperative 1-year follow-up. Conclusions: Decompression-only for low-grade degenerative spondylolisthesis has good long-term results despite instability. Further higher-level studies should be performed on this patient group with radiological instability to suggest the superior surgical option.

        APSS-ASJ Best Clinical Research Award: Predictability of Curve Progression in Adolescent Idiopathic Scoliosis Using the Distal Radius and Ulna Classification

        Jason Pui Yin Cheung,Prudence Wing Hang Cheung,Dino Samartzis,Keith Dip-Kei Luk 대한척추외과학회 2018 Asian Spine Journal Vol.12 No.2

        Study Design: Prospective study. Purpose: To determine the risk of clinically significant curve progression in adolescent idiopathic scoliosis (AIS) based on the initial Cobb angle and to test the utility of the distal radius and ulna (DRU) classification in predicting these outcomes. Overview of Literature: Determining the remaining growth potential in AIS patients is necessary for predicting prognosis and initiating treatment. Limiting the maturity Cobb angle to <40° and <50° reduces the risk of adulthood progression and need for surgery, respectively. The risk of curve progression is the greatest with skeletally immature patients and thus warrants close monitoring or early intervention. Many parameters exist for measuring the skeletal maturity status in AIS patients, but the DRU classification has been shown to be superior in predicting peak growth and growth cessation. However, its predictive capabilities for curve progression are unknown. Methods: Totally, 513 AIS patients who presented with Risser 0–3 were followed until either skeletal maturity or the need for surgery, with a minimum 2-year follow-up period. Outcomes of 40° and 50° were used for probability analysis based on the cut-offs of adulthood progression risk and surgical threshold, respectively. Results: At the R6/U5 grade, most curves (probability of ≥48.1%–55.5%) beyond a Cobb angle of 25° progressed to the 40° threshold. For curves of ≥35°, there was a high risk of unfavorable outcomes, regardless of skeletal maturity. Most patients with the R9 grade did not progress, regardless of the initial curve magnitude (probability of 0% to reach the 50° threshold for an initial Cobb angle of ≥35°). Conclusions: This large-scale study illustrates the utility of the DRU classification for predicting curve progression and how it may effectively guide the timing of surgery. Bracing may be indicated for skeletally immature patients at an initial Cobb angle of 25°, and those with a scoliosis ≥35° are at an increased risk of an unfavorable outcome, despite being near skeletal maturity.

        Variations in Practice among Asia–Pacific Surgeons and Recommendations for Managing Cervical Myelopathy: The First Asia–Pacific Spine Society Collaborative Study

        Jason Pui Yin Cheung,Prudence Wing Hang Cheung,Chee Kidd Chiu,Chris Yin Wei Chan,Mun Keong Kwan 대한척추외과학회 2019 Asian Spine Journal Vol.13 No.1

        Study Design: Surgeon survey. Purpose: To study the various surgical practices of different surgeons in the Asia–Pacific region. Overview of Literature: Given the diversity among Asia–Pacific surgeons, there is no clear consensus on the preferred management strategies for cervical myelopathy. In particular, the role of prophylactic decompression for silent cervical spinal stenosis is under constant debate and should be addressed. Methods: Surgeons from the Asia–Pacific Spine Society participated in an online questionnaire comprising 50 questions. Data on clinical diagnosis, investigations and outcome measures, approach to asymptomatic and silent cervical spinal stenosis, guidelines for surgical approach, and postoperative immobilization were recorded. All parameters were analyzed by the Mantel–Haenszel test. Results: A total of 79 surgeons from 16 countries participated. Most surgeons used gait disturbance (60.5%) and dyskinetic hand movement (46.1%) for diagnosis. Up to 5.2% of surgeons would operate on asymptomatic spinal stenosis, and 18.2% would operate on silent spinal stenosis. Among those who would not operate, most (57.1%) advised patients on avoidance behavior and up to 9.5% prescribed neck collars. For ossification of the posterior longitudinal ligament (OPLL), anterior removal was most commonly performed for one-level disease (p <0.001), whereas laminoplasty was most commonly performed for two- to four-level disease (p =0.036). More surgeons considered laminectomy and fusion for multilevel OPLL. Most surgeons generally preferred to use a rigid neck collar for 6 weeks postoperatively (p <0.001). Conclusions: The pooled recommendations include prophylactic or early decompression surgery for patients with silent cervical spinal stenosis, particularly OPLL. Anterior decompression is primarily suggested for one- or two-level disease, whereas laminoplasty is preferred for multilevel disease.
