A STUDY ON PROBLEMS IN SPEAKING OF ENGLISH-MAJORED FRESHMEN AT TAY DO UNIVERSITY AND SOME SUGGESTED SOLUTIONS

In this globalization era, there have been drastic changes taking place all over the world. People’s desires are fulfilled when they clearly express their ideas and opinions to others. Thus, they need to learn speaking skills in order to fulfill their ambitions, desires, and goals. However, it is so difficult for students to master this skill because they encounter some common problems when speaking. Therefore, the research entitled "A study on problems in speaking of English-majored freshmen at Tay Do University and some suggested solutions" was carried out in order to identify common problems in English speaking of English majored freshmen at Tay Do University and provide some suggested solutions. In this study, questionnaires and interview papers were used as the main instruments to collect the data. The participants were 80 English-majored freshmen in the two classes of English course 16 including 16A and 16B at Tay Do University. The study's findings revealed that freshmen majoring in English had several common problems with vocabulary, pronunciation, grammar, the influence of mother tongue, and psychology in speaking. It is expected that this study will assist English-majored freshmen at Tay Do University in recognizing and overcoming obstacles in the process of speaking.  Article visualizations

Safety and efficacy of fluoxetine on functional outcome after acute stroke (AFFINITY): a randomised, double-blind, placebo-controlled trial

Background Trials of fluoxetine for recovery after stroke report conflicting results. The Assessment oF FluoxetINe In sTroke recoverY (AFFINITY) trial aimed to show if daily oral fluoxetine for 6 months after stroke improves functional outcome in an ethnically diverse population. Methods AFFINITY was a randomised, parallel-group, double-blind, placebo-controlled trial done in 43 hospital stroke units in Australia (n=29), New Zealand (four), and Vietnam (ten). Eligible patients were adults (aged ≥18 years) with a clinical diagnosis of acute stroke in the previous 2–15 days, brain imaging consistent with ischaemic or haemorrhagic stroke, and a persisting neurological deficit that produced a modified Rankin Scale (mRS) score of 1 or more. Patients were randomly assigned 1:1 via a web-based system using a minimisation algorithm to once daily, oral fluoxetine 20 mg capsules or matching placebo for 6 months. Patients, carers, investigators, and outcome assessors were masked to the treatment allocation. The primary outcome was functional status, measured by the mRS, at 6 months. The primary analysis was an ordinal logistic regression of the mRS at 6 months, adjusted for minimisation variables. Primary and safety analyses were done according to the patient's treatment allocation. The trial is registered with the Australian New Zealand Clinical Trials Registry, ACTRN12611000774921. Findings Between Jan 11, 2013, and June 30, 2019, 1280 patients were recruited in Australia (n=532), New Zealand (n=42), and Vietnam (n=706), of whom 642 were randomly assigned to fluoxetine and 638 were randomly assigned to placebo. Mean duration of trial treatment was 167 days (SD 48·1). At 6 months, mRS data were available in 624 (97%) patients in the fluoxetine group and 632 (99%) in the placebo group. The distribution of mRS categories was similar in the fluoxetine and placebo groups (adjusted common odds ratio 0·94, 95% CI 0·76–1·15; p=0·53). Compared with patients in the placebo group, patients in the fluoxetine group had more falls (20 [3%] vs seven [1%]; p=0·018), bone fractures (19 [3%] vs six [1%]; p=0·014), and epileptic seizures (ten [2%] vs two [<1%]; p=0·038) at 6 months. Interpretation Oral fluoxetine 20 mg daily for 6 months after acute stroke did not improve functional outcome and increased the risk of falls, bone fractures, and epileptic seizures. These results do not support the use of fluoxetine to improve functional outcome after stroke

The role of capital structure management in maintaining the financial stability of hotel firms during the pandemic—A global investigation

Due to the detrimental effects of the Covid-19 pandemic on the hotel sector, pandemic crisis management research has received lots of academic attention, from studies in sales-marketing to human resource management. However, financial management has been largely overlooked in the agenda of pandemic crisis management and hotel resilience. Therefore, this paper aims to address the research gap by exploring the role of capital structure management in maintaining financial stability and resilience capacities of hotel firms during this evolving and unpredictable Covid-19 pandemic. Using a database of 1882 firm-quarter observations of 196 hotel firms in 30 countries from Quarter 3 2018 to Quarter 2 2021, it is found that low debt capital structure mitigates the adverse impact of the pandemic on hotel firms’ financial stability during this turbulent time; particularly the negative impacts caused by government restrictions on both domestic and international travel. The benefit of low debt levels is more pronounced for more vulnerable hotels such as small, less diversified, and slow growing hotel firms. Also, hotel firms that have less long-term debt are more financial stable and resilient during pandemic period. Research outcomes suggest that financial management, in particular capital structure policies should be a critical part of hotel resilience building and crisis management strategy for hotel firms

From Rice Bowl to Rural Development: Challenges and Opportunities Facing Vietnam’s Mekong Delta Region

The Mekong Delta has long been a major producing area for Vietnamese rice. It now accounts for more than half of national production and accounted for most of the growth in that production over the past decade. While this has given the Mekong Delta the reputation as Vietnam’s ‘rice bowl’—critical for national food security—virtually all of its incremental production (and now 70% of its output) has been channeled into exports. With Vietnam’s rice export trade mostly servicing the low price market segment, and with shortcomings in efficiency and coordination within the export supply chain, the surging export trade has not translated into wealth among Mekong Delta farmers. The paper examines the evolving dynamics in rice production and economics in the Mekong Delta, pertinent features of the structure and performance of the rice value chain, and the challenges and opportunities associated both with improving efficiencies and profitability for rice and with promoting a more balanced pattern of rural development within the region

Formation and Evaluation of Complete Blood Count Proficiency Testing Program

Introduction: The haematology external quality assessment (EQA) scheme is the most commonly used service of quality assurance. The provision of complete blood count (CBC) materials must meet the quality requirements at a reasonable cost. These requirements are the most significant challenges for EQA organisers in Vietnam. This study’s objective was to evaluate the homogeneity, long-term stability, and peer-group performance of 10-parameter stabilised CBC EQA samples. Methods: The CBC EQA material was prepared using the following steps, including (1) adjusting levels of stabilised erythrocyte, leukocyte, and platelet samples, (2) mixing those cells into batches at three levels, and (3) dispensing and storing them at 2–6 °C. A set of 10 and 30 specimens were randomly chosen from each batch to study the homogeneity and long-term stability following ISO 13528:2015. In total, 166 samples at two levels were randomly distributed to 40 participants, which reported 83 automatic cell counters among six automated analyser models in the CBC EQA program. Results: The 10-parameter stabilised CBC EQA materials at three levels became homogeneous and stable in 12 weeks when preserved at 2–6 °C. Meanwhile, for five parameters (RBC, Hb, MCH, MCV, and MPV), this process was prolonged for up to 16 weeks in stock condition. In terms of peer-group performance, the CV (%) values increased at the low concentration for almost all parameters, especially in platelet counts. Conclusions: The stabilised CBC EQA samples prepared using the partial fixation method with aldehyde and gutaraldehyde in this study meet the ISO 13528:2015 requirements of homogeneity and long-term stability for the CBC EQA scheme. Analytical performance evaluation should categorise participant methods into peer groups
