Understanding International Students' Learning Experiences of English as a Medium of Instruction Courses

This study aims to understand international students' learning experiences in English as a medium of instruction (EMI) courses in a private Korean university. By using mixed-method research, this study collected two data sources, including 1) an online survey (n=46) and 2) an individual in-depth interview (n=4) at the end of the 2022 Spring semester. The study results are summarized as follows. First, EMI courses could enhance international students' content knowledge development effectively. Second, EMI courses could improve international students' English proficiency in terms of reading and vocabulary ability. Third, international students showed high satisfaction with EMI courses and are willing to take EMI courses continuously. However, the interview analysis showed that it was challenging for a few international students to improve their English speaking ability due to limited opportunities to speak English during graduate-level courses. These study results suggest several recommendations to provide practical EMI courses for teaching diverse international students, including English language learners in higher education

A STUDY ON THE LONG-TERM MONITORING OF SPORTS ACTIVITIES

INTRODUCTION: Lots of studies to analyze and classify human movement patterns using various sensors have been carried out (Mathie, 2004; Allen, 2006) because accurate information of body activity is required to provide promotion of health and health plan. Thus this study was conducted to study the classification and monitoring of various sports activities in real-time environment using single waist mounted tri-axial accelerometer

A STUDY ON THE GRIP FORCE DURING PUTTING STROKE

There are lots of variables to affect the control of ball movement during golf putting. Among several variables, it is believed that grip force during putting stroke is one of the important variables. However, there is not much quantitative evidence from published literature (Delay 1997, Gwyn 1993). Therefore, the purpose of this study was to quantify the grip force by comparing putts performed by elite and novice golfers and to identify the relationship between kinematic parameters and the grip force at 16 different parts of subjects’ right and left hand at each putting phase

Effect of intradialytic change in blood pressure and ultrafiltration volume on the variation in access flow measured by ultrasound dilution

AbstractBackgroundProspective access flow measurement is the preferred method for vascular access surveillance in hemodialysis (HD) patients. We studied the effect of intradialytic change in blood pressure and ultrafiltration volume on the variation in access flow measured by ultrasound dilution.MethodsAccess flow was measured 30minutes, 120minutes, and 240minutes after the start of HD by ultrasound dilution in 30 patients during 89 HD sessions and evaluated for variation.ResultsThe mean age of the 30 patients was 62±11 years: 19 were male. The accesses comprised 16 fistulae and 14 grafts. The mean access flow over all sessions decreased by 6.1% over time (1265±568mL/min after 30minutes, 1260±599mL/min after 120minutes, and 1197±576mL/min after 240minutes, P<0.01 by repeated measures ANOVA). In addition, a≥5% decrease in mean arterial pressure during HD significantly reduced access flow (P=0.014). However, no other variable (ultrafiltration volume, sex, age, presence of diabetes, type or location of access, body surface area, hemoglobin, serum albumin level) interacted significantly with the effect of time on access flow. Furthermore, mean arterial pressure did not correlate with ultrafiltration volume.ConclusionWe conclude that the variation in access flow during HD is relatively small. Decreased blood pressure is a risk factor for variation in access flow measured by ultrasound dilution. In most patients whose blood pressures are stable during HD, the access flow can be measured at any time during the HD treatment

Association of circulating omentin-1 level with arterial stiffness and carotid plaque in type 2 diabetes

<p>Abstract</p> <p>Background</p> <p>Adipokines contribute directly to the atherosclerotic process, connecting metabolic disorders such as obesity and diabetes to cardiovascular disease. Omentin-1 is a recently discovered novel adipokine, so data about the relationship of this adipokine to vascular health in type 2 diabetes is limited.</p> <p>Methods</p> <p>We enrolled 60 people with type 2 diabetes, with or without carotid plaque, and 30 participants with normal glucose tolerance. We measured serum omentin-1, high-sensitivity C-reactive protein (hsCRP) levels, and the homeostasis model assessment of insulin resistance (HOMA-IR), as well as other cardiovascular risk factors. Vascular health was assessed by brachial ankle pulse wave velocity (baPWV) and carotid intima-media thickness (IMT).</p> <p>Results</p> <p>Serum omentin-1 levels were significantly decreased in type 2 diabetes patients compared to normal glucose controls and was further reduced in type 2 diabetes patients with carotid plaque compared to those without carotid plaque. Multiple stepwise regression analysis showed that age, systolic blood pressure, history of use of statins, angiotensin receptor blockers or angiotensin-converting enzyme inhibitors, and serum omentin-1 level were independent factors determining baPWV in people with type 2 diabetes (<it>r</it>²= 0.637). Furthermore, in multivariate logistic regression analysis, circulating omentin-1 level was an independent decisive factor for the presence of carotid plaque in type 2 diabetes patients, even after adjusting for age, gender, body mass index, systolic blood pressure, fasting blood glucose, low density lipoprotein cholesterol, and history of smoking and medication (odds ratio, 0.621; 95% confidence interval, 0.420-0.919; <it>P </it>= 0.017).</p> <p>Conclusions</p> <p>Circulating omentin-1 level was independently correlated with arterial stiffness and carotid plaque in type 2 diabetes, even after adjusting for other cardiovascular risk factors and detailed medication history.</p
