WILLINGNESS OF LABOURERS TO MIGRATE FOR WORK: A SURVEY STUDY IN VIETNAM

The 13th Next-Generation Global Workshop第13回次世代グローバルワークショップテーマ: New Risks and Resilience in Asian Societies and the World 日程: 21-23 November, 2020 開催場所: ベトナム社会科学院(ハノイ)/Vietnam Academy of Social Sciences(No. 1 Lieu Giai street, Ba Dinh, Hanoi, Vietnam) ※Due to the COVID-19, the workshop will be held at ONLINE for overseas participants(not from Vietnam)/ONSITE for Vietnamese participants.The paper is written based on the research on labourers' interest in the Fourth Industrial Revolution (4.0 I.R.) with surveyed sample of 319 people who are working in the enterprises. The statistics analysis method was applied to analyze data. Probit regression model is also approached to quantitatively analyze. The study aims to examine the relationship between historical migration experiences and ability of working migration that a labor may intend in the future. The factors that simultaneously impact on worker's migration decision in the future are two-level migration, marriage status, having children less than 15 years old and living with other members in the family. These effects pointed out significant evidences in this study

DIFFICULTIES WITH WORD CHOICE IN ACADEMIC WRITING AND SOLUTIONS: A RESEARCH ON ENGLISH-MAJORED STUDENTS AT CAN THO UNIVERSITY, VIETNAM

Writing, especially academic writing, is highly valued in foreign language acquisition, particularly for English majors. Nevertheless, using academic terminology might be difficult for students still developing their academic language abilities. The purpose of this research is to understand students' difficulties in selecting appropriate words in academic writing and offer solutions to overcome such difficulties. The participants were 78 English majors (high-quality program, course 45) and three lecturers at the Department of English Language and Culture, School of Foreign Languages, Can Tho University. Questionnaires were used to measure their difficulties in word choice in academic writing and semi-structured interviews were utilized to find solutions. The results show that most participants had a basic knowledge of academic vocabulary, which was demonstrated through their ability to select the appropriate word choice. However, students found it difficult to choose the right words in their academic writing. The reasons are that academic words are not easy to remember and not successfully used in the context of the meaning of the word and do not have an effective method of learning academic vocabulary. Based on the results, several specific approaches have been proposed to help students find the most suitable strategies for learning and using academic vocabulary for their writing.  Article visualizations

Modeling quality of life of Ho Chi Minh City dwellers

Quality of life (QoL) has received more and more attention from scholars and researchers from various fields such as healthcare, philosophy, psychology, sociology, and especially economics after many decades of focusing on income. However, researchers have faced many challenges to gain the proper measurement of QoL due to the contextually based concept. This study employs the primary data conducted in Ho Chi Minh City including 500 observations in 2022, with the application of partial least squares structural equation modeling (PLS-SEM) to construct a hierarchical model to measure the QoL of the dwellers in Ho Chi Minh City. The empirical model supports the multi-level hierarchical structure of the QoL. The statistically significant contribution of economic, social, and environmental dimensions in the integrated index has been confirmed. The environmental component shares the highest weight, followed by the economic factor. The social aspect contributes the least share in the quality- of-life index. Further analysis of the sub-criteria in each dimension has been made. The findings implicitly suggest the policy concentration on sustainable factors enhancement to raise the QoL. It was a milestone for policy makers to switch the focus from material to non-material factors in the life quality model in Vietnam

Age-time-specific transmission of hand-foot-and-mouth disease enterovirus serotypes in Vietnam: a catalytic model with maternal immunity

Hand, foot and mouth disease (HFMD) is highly prevalent in the Asia Pacific region, particularly in Vietnam. To develop effective interventions and efficient vaccination programs, we inferred the age-time-specific transmission patterns of HFMD serotypes enterovirus A71 (EV-A71), coxsackievirus A6 (CV-A6), coxsackievirus A10 (CV-A10), coxsackievirus A16 (CV-A16) in Ho Chi Minh City, Vietnam from a case data collected during 2013–2018 and a serological survey data collected in 2015 and 2017. We proposed a catalytic model framework with good adaptability to incorporate maternal immunity using various mathematical functions. Our results indicate the high-level transmission of CV-A6 and CV-A10 which is not obvious in the case data, due to the variation of disease severity across serotypes. Our results provide statistical evidence supporting the strong association between severe illness and CV-A6 and EV-A71 infections. The HFMD dynamic pattern presents a cyclical pattern with large outbreaks followed by a decline in subsequent years. Additionally, we identify the age group with highest risk of infection as 1-2 years and emphasise the risk of future outbreaks as over 50% of children aged 6-7 years were estimated to be susceptible to CV-A16 and EV-A71. Our study highlights the importance of multivalent vaccines and active surveillance for different serotypes, supports early vaccination prior to 1 year old, and points out the potential utility for vaccinating children older than 5 years old in Vietnam

Detection of Staphylococci from nasal samples from healthy and sick dogs in Ho Chi Minh City, Vietnam

Staphylococci are one of the most commonly found opportunistic bacteria in animals and human. The objective of this study was to determine the prevalence of Staphylococcus spp. isolated from healthy and sick dogs visiting veterinary clinics in Ho Chi Minh city, Vietnam from January 2022 to December 2022. A total of 123 nasal swab samples were collected, including 40 samples from healthy dogs and 83 samples from dogs with respiratory symptoms. Staphylococcus spp. were isolated from 47.5% of healthy animals and 60.24% of dogs showing respiratory symptoms. The study showed that isolation rates from confined, semi-confined and free-ranging dogs were 75.86%, 54.84% and 40.63%, respectively. Furthermore, the prevalence was higher in dogs over one year old compared to younger dogs (64.10% and 42.22%, respectively). Several subspecies of Staphylococci, including S. aureus, S. pseudintermedius and S. epidermidis were identified, in which S. pseudintermedius accounted for the highest proportion (48.28%). The prevalence of S. pseudintermedius also varied across different age groups. Coagulase activity of the isolated Staphylococcus strains was also determined and indicated that coagulase-positive Staphylococci constituted 80.46% of the isolates. This study represents the first report on the prevalence of Staphylococci in dogs in Vietnam and reemphasizes the zoonotic significance of Staphylococcus at the interface between dogs and humans

PRESENT DAY DEFORMATION IN THE EAST VIETNAM SEA AND SURROUNDING REGIONS

This paper presents velocities of present-day tectonic movement and strain rate in the East Vietnam Sea (South China Sea) and surroundings determined from GPS campaigns between 2007 and 2010. We determine absolute velocities of GPS stations in the ITRF05 frame. The result indicates that GPS stations in the North of East Vietnam Sea move eastwards with the slip rate of 30 - 39 mm/yr, southwards at the velocities of 8 - 11 mm/yr. Song Tu Tay offshore moves eastwards at the rate of ~24 mm/yr and southwards at ~9 mm/yr. GPS stations in the South of East Vietnam Sea move to the east at the rate of ~22 mm/yr and to the south at the velocities of 7 - 11 mm/yr. The effect of relative movement shows that the Western Margin Fault Zone activates as left lateral fault zone at the slip rate less than 4 mm/year.In Western plateau, the first result from 2012 - 2013 GPS measurement shows that the velocities to the east vary from 21.5 mm/yr to 24.7 mm/year. The velocities to the south vary from 10.5 mm/yr to 14.6 mm/year. GPS solutions determined from our campaigns are combined with data from various authors and international projects to determine the strain rate in the East Vietnam Sea. Principal strain rate changes from 15 nanostrain/yr to 9 nanostrain/yr in the East Vietnam Sea. Principal strain rate and maximum shear strain rate along the Red River Fault Zone are in order of 10 nanostrain/year. East Vietnam Sea is considered to belong to the Sunda block

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

Factors associated with food safety compliance among street food vendors in Can Tho city, Vietnam: Implications for intervention activity design and implementation

Background Street food plays a valuable role in several Asian countries including Vietnam. Improving the safety of street food is an important responsibility for many local food authorities. This study aims to characterize the business profile of fixed and mobile street food vendors, and to compare their compliance with the food safety criteria. Methods A cross-sectional study was conducted using a questionnaire and observational checklist to assess the ten Vietnamese food safety criteria prescribed under Decision No. 3199/2000/QD-BYT for street food vendors in Can Tho city. A total of 400 street food vendors, composed of fixed and mobile vendors, in urban areas of the city were randomly selected for the survey. Results The study showed significant differences between the two types of street food vendors in educational level (p = 0.017); business profile, including types of foods vended, area in use, number of employees, training in food safety, and business registration paperwork; and the status of compliance with the ten-food hygiene and safety criteria (p < 0.01). Poisson regression analysis found that education attainment (IRR = 1.228, p = 0.015), food safety training (IRR = 4.855, p < 0.01), total business capital (IRR = 1.004, p = 0.031) and total area in use (IRR = 1.007, p = 0.001) appeared to be significantly positively associated with food safety and hygiene compliance. In contrast, mobile vending type was negatively associated with the likelihood of adhering to the ten criteria (IRR = 0.547, p = 0.005). Conclusions These findings emphasize the need for training and education programs to improve food safety knowledge and practice among street food vendors. Basic infrastructure and services, especially clean water, proper sanitation, and waste disposal facilities, should be provided to help street food vendors better practice food safety and hygiene regulations
