Exploiting Idioms and Proverbs of Vietnamese Regions in Teaching Mathematics in Primary Schools

Mathematics and idioms, as well as proverbs, all reflect the laws of life. At the same time, primary school children may have heard idioms and proverbs before attending school. Therefore, there are many possibilities to exploit and apply idioms and proverbs in teaching mathematics in primary schools. This study aims to identify appropriate situations and apply idioms and proverbs in different regions of Vietnam to teaching mathematics. The researchers selected 1155 expressions related to mathematics from many typical pieces of research on idioms and proverbs in Vietnam. After surveying 1822 teachers three times in many provinces and cities in all 3 regions of Vietnam: the North, the Central and the South, the researchers have classified the data according to the criteria from closed to open-ended questions. The results show a prominent level of interest (level 4/5) of all teachers participating in the survey, and there is no difference in the effectiveness in the three regions, but there is a clear difference in regions in using idioms and proverbs. Particularly, identifying situations to teach geometric and quantitative knowledge, as well as probability and statistics, allows one to apply idioms and proverbs at a high level. It is concluded that if idioms and proverbs from Vietnamese regions are appropriately selected and applied in teaching mathematics in primary schools, they will contribute to improving students' mathematical ability and preserving the national cultural heritage. Doi: 10.28991/ESJ-2022-SIED-015 Full Text: PD

Trends in, projections of, and inequalities in reproductive, maternal, newborn and child health service coverage in Vietnam 2000-2030: A Bayesian analysis at national and sub-national levels

Background: To assess the reproductive, maternal, newborn and child health (RMNCH) service coverage in Vietnam with trends in 2000-2014, projections and probability of achieving targets in 2030 at national and sub-national levels; and to analyze the socioeconomic, regional and urban-rural inequalities in RMNCH service indicators. Methods: We used national population-based datasets of 44,624 households in Vietnam from 2000 to 2014. We applied Bayesian regression models to estimate the trends in and projections of RMNCH indicators and the probabilities of achieving the 2030 targets. Using the relative index, slope index, and concentration index of inequality, we examined the patterns and trends in RMNCH coverage inequality. Findings: We projected that 9 out of 17 health service indicators (53%) would likely achieve the 2030 targets at the national level, including at least one and four ANC visits, BCG immunization, access to improved water and adequate sanitation, institutional delivery, skilled birth attendance, care-seeking for pneumonia, and ARI treatment. We observed very low coverages and zero chance of achieving the 2030 targets at national and sub-national levels in early initiation and exclusive breastfeeding, family planning needs satisfied, and oral rehydration therapy. The most deprived households living in rural areas and the Northwest, Northeast, North Central, Central Highlands, and Mekong River Delta regions would not reach the 80% immunization coverage of DPT3, Polio3, Measles and full immunization. We found socioeconomic, regional, and urban-rural inequalities in all RMNCH indicators in 2014 and no change in inequalities over 15 years in the lowest-coverage indicators. Interpretation: Vietnam has made substantial progress toward UHC. By improving the government\u27s health system reform efforts, re-allocating resources focusing on people in the most impoverished rural regions, and restructuring and enhancing current health programs, Vietnam can achieve the UHC targets and other health-related SDGs

Inequalities in non-communicable diseases in urban Hanoi, Vietnam : health care utilization, expenditure and responsiveness of commune health stations

Background: Non-communicable diseases (NCDs) are the leading causes of morbidity and mortality among adults in Vietnam. Little is known about the magnitude of socioeconomic inequalities in NCDs and other NCD-related factors in urban areas, in particular among the poor living in slum areas. Understanding these disparities are essential in contributing to the knowledge, needed to reduce inequalities and close the related health gaps burdening the disadvantaged populations in urban areas.  Objective: To examine the burden and health system responsiveness to NCDs in Hanoi, Vietnam and investigate the role of socioeconomic inequalities in their prevalence, subsequent healthcare utilization and related impoverishment due to health expenditures.  Methods: A cross-sectional study was conducted among 3,736 individuals aged 15 years and over who lived in 1211 randomly selected households in 2013 in urban Hanoi, Vietnam. The study collected information on household’s characteristics, household expenditures, and household member information. A qualitative approach was implemented to explore the responsiveness of commune health stations to the increasing burden of NCDs in urban Hanoi. In-depth interview approach was conducted among health staff involved in NCD tasks at four commune health stations in urban Hanoi. Furthermore, NCD managers at relevance district, provincial and national levels were interviewed.  Results: The prevalence of self-reported NCDs was significantly higher among individuals in non-slum areas (11.6%) than those in slum areas (7.9%). However, the prevalence of self-reported NCDs concentrated among the poor in both slum and non-slum areas. In slum areas, the poor needed more health care services, but the rich consumed more health care services. Among households with at least one household member reporting diagnosis of NCDs, the proportion of household facing catastrophic health expenditure and impoverishment were the greater in slum areas than in non-slum areas. Poor households in slum areas were more likely to face catastrophic health expenditure and impoverishment. The poor in non-slum areas were also more likely to face impoverishment if their household members experienced NCDs. Health system responses to NCDs at commune health stations in urban Hanoi were weak, characterized by the lack of health information, inadequate human resources, poor financing, inadequate quality and quantity of services, lack of essential medicines. The commune health stations were not prepared to respond to the rising prevalence of NCDs in urban Hanoi.  Conclusion: This thesis shows the existence of socioeconomic inequalities in the prevalence of self-reported NCDs in both non-slum and slum areas in urban Hanoi. NCDs associated with the inequalities in health care utilization, catastrophic health expenditure and impoverishment, particular in slum areas. Appropriate interventions should focus more on specific population groups to reduce the socioeconomic inequalities in the NCD prevalence and health care utilization related to NCDs to prevent catastrophic health expenditure and impoverishment among the households of NCD patients.  The functions of commune health stations in the urban setting should be strengthened through the development of NCDs service packages covered by the health insurance

Horizontal inequity in public health care service utilization for non-communicable diseases in urban Vietnam

BACKGROUND: A health system that provides equitable health care is a principal goal in many countries. Measuring horizontal inequity (HI) in health care utilization is important to develop appropriate and equitable public policies, especially policies related to non-communicable diseases (NCDs). DESIGN: A cross-sectional survey of 1,211 randomly selected households in slum and non-slum areas was carried out in four urban districts of Hanoi city in 2013. This study utilized data from 3,736 individuals aged 15 years and older. Respondents were asked about health care use during the previous 12 months; information included sex, age, and self-reported NCDs. We assessed the extent of inequity in utilization of public health care services. Concentration indexes for health care utilization and health care needs were constructed via probit regression of individual utilization of public health care services, controlling for age, sex, and NCDs. In addition, concentration indexes were decomposed to identify factors contributing to inequalities in health care utilization. RESULTS: The proportion of healthcare utilization in the slum and non-slum areas was 21.4 and 26.9%, respectively. HI in health care utilization in favor of the rich was observed in the slum areas, whereas horizontal equity was achieved among the non-slum areas. In the slum areas, we identified some key factors that affect the utilization of public health care services. CONCLUSION: Our results suggest that to achieve horizontal equity in utilization of public health care services, policy should target preventive interventions for NCDs, focusing more on the poor in slum areas

Socioeconomic inequalities in catastrophic health expenditure and impoverishment associated with non-communicable diseases in urban Hanoi, Vietnam

Background: The catastrophic health expenditure and impoverishment indices offer guidance for developing appropriate health policies and intervention programs to decrease financial inequity. This study assesses socioeconomic inequalities in catastrophic health expenditure and impoverishment in relation to self-reported non-communicable diseases (NCD) in urban Hanoi, Vietnam. Methods: A cross-sectional survey was conducted from February to March 2013 in Hanoi, the capital city of Vietnam. We estimated catastrophic health expenditure and impoverishment using information from 492 slum household and 528 non-slum households. We calculated concentration indexes to assess socioeconomic inequalities in catastrophic health expenditure and impoverishment. Factors associated with catastrophic health expenditure and impoverishment were modelled using logistic regression analysis. Results: The poor households in both slum and non-slum areas were at higher risk of experiencing catastrophic health expenditure, while only the poor households in slum areas were at higher risk of impoverishment because of healthcare spending. Households with at least one member reporting an NCD were significantly more likely to face catastrophic health expenditure (odds ratio [OR] = 2.4; 95 % confidence interval [CI], 1.8-4.0) and impoverishment (OR = 2.3; 95 % CI, 1.1-6.3) compared to households without NCDs. In addition, households in slum areas, with people age 60 years and above, and belonging to the poorest socioeconomic group were significantly associated with increased catastrophic health expenditure, while only households that lived in slum areas, and belonging to the poor or poorest socioeconomic groups were significantly associated with increased impoverishment because of healthcare spending. Conclusion: Financial interventions to prevent catastrophic health expenditure and impoverishment should target poor households, especially those with family members suffering from NCDs, with older members and those located in slum areas in Hanoi Vietnam. Potential interventions derived from this study include targeting and monitoring of health insurance enrolment, and developing a specialized NCD service package for Vietnam's social health insurance program

Trends in childhood measles vaccination highlight socioeconomic inequalities in Vietnam

OBJECTIVES: To describe trends in measles vaccine coverage rates and their association with socioeconomic characteristics among children from age 12 to 23 months in Vietnam from the year 2000 to 2014. METHODS: Data were drawn from the Vietnam Multiple Indicator Cluster Surveys in years 2000, 2006, 2011, and 2014. Concentration indices were used to determine the magnitude of socioeconomic inequalities in measles vaccine coverage. Associations between measles vaccine coverage and relevant social factors were assessed using logistic regression. RESULTS: Socioeconomic inequalities in measles vaccine coverage rates decreased during 2000-2014. Children belonging to ethnic minority groups, having mothers with lower education, and belonging to the poorest group were less likely to receive measles vaccine; although, their vaccine coverage rates did increase with time. Measles vaccine coverage declined among children of mothers with more education and belonging to the wealthiest socioeconomic group. CONCLUSIONS: Understanding the social factors influencing adherence to recommend childhood vaccination protocols is essential. Attempts to regain and retain herd immunity must be guided by an understanding of these social factors if they are to succeed.Supplement 1: Health and social determinants of health in Vietnam: local evidence and international implications’</p

ERI-MAC: An Energy-Harvested Receiver-Initiated MAC Protocol for Wireless Sensor Networks

Energy harvesting technology potentially solves the problem of energy efficiency, which is the biggest challenge in wireless sensor networks. The sensor node, which has a capability of harvesting energy from the surrounding environment, is able to achieve infinitive lifetime. The technology promisingly changes the fundamental principle of communication protocols in wireless sensor networks. Instead of saving energy as much as possible, the protocols should guarantee that the harvested energy is equal to or bigger than the consumed energy. At the same time, the protocols are designed to have the efficient operation and maximum network performance. In this paper, we propose ERI-MAC, a new receiver-initiated MAC protocol for energy harvesting sensor networks. ERI-MAC leverages the benefit of receiver-initiated and packet concatenation to achieve good performance both in latency and in energy efficiency. Moreover, ERI-MAC employs a queueing mechanism to adjust the operation of a sensor node following the energy harvesting rate from the surrounding environment. We have extensively evaluated ERI-MAC in a large scale network with a realistic traffic model using the network simulator ns-2. The simulation results show that ERI-MAC achieves good network performance, as well as enabling infinitive lifetime of sensor networks

Perceptions of climate change and its impact on human health: an integrated quantitative and qualitative approach

Background: The World Health Organization emphasized that climate change is a significant and emerging threat to public health, especially in lower income populations and tropical/subtropical countries. However, people in Asia and Africa were the least likely to perceive global warming as a threat. In Vietnam, little research has been conducted concerning the perceptions of effects of climate change on human health. Objective: The aim of this study was to explore the perceptions on climate change and its impact on human health among people in Hanoi. Design: We applied a combined quantitative and qualitative approach to study perceptions on climate change among people in Hanoi. A total of 1,444 people were recruited, including 754 people living in non-slum areas and 690 people living in slum areas of Hanoi. A structured questionnaire was used to collect quantitative data on their perceptions. In a parallel qualitative study, two focus group discussions and 12 in-depth interviews (IDs) were carried out involving 24 people from both slum and non-slum areas. Results: The majority of the respondents in the study had heard about climate change and its impact on human health (79.3 and 70.1% in non-slum and slum areas, respectively). About one third of the respondents reported that members of their family had experienced illness in the recent summer and winter compared to the same seasons 5 years ago. The most common symptoms reported during hot weather were headaches, fatigue, and dizziness; hypertension and other cardiovascular diseases were also reported. During cold weather, people reported experiencing cough, fever, and influenza, as well as pneumonia and emerging infectious diseases such as dengue and Japanese encephalitis. Conclusions: The observed high level of awareness on the links between climate change and human health may help to increase the success of the National Prevention Program on Climate Change. Moreover, understanding the concerns of the people may help policy makers to develop and implement effective and sustainable adaptation measures for Hanoi City as well as for Vietnam as a whole

Socioeconomic inequalities in self-reported chronic non-communicable diseases in urban Hanoi, Vietnam

This study measures and decomposes socioeconomic inequalities in the prevalence of self-reported chronic non-communicable diseases (NCDs) in urban Hanoi, Vietnam. A cross-sectional survey of 1211 selected households was carried out in four urban districts in both slum and non-slum areas of Hanoi city in 2013. The respondents were asked if a doctor or health worker had diagnosed any household members with an NCD, such as cardiovascular diseases, chronic respiratory, diabetes or cancer, during last 12 months. Information from 3736 individuals, aged 15 years and over, was used for the analysis. The concentration index (CI) was used to measure inequalities in self-reported NCD prevalence, and it was also decomposed into contributing factors. The prevalence of chronic NCDs in the slum and non-slum areas was 7.9% and 11.6%, respectively. The CIs show gradients disadvantageous to both the slum (CI = −0.103) and non-slum (CI = −0.165) areas. Lower socioeconomic status and aging significantly contributed to inequalities in the self-reported NCDs, particularly for those living in the slum areas. The findings confirm the existence of substantial socioeconomic inequalities linked to NCDs in urban Vietnam. Future policies should target these vulnerable areas
