Abstract: Sustainable development is an indispensable trend belong to global strategic in order to tackle severe conflicts in economic development (economic growth), social stability (advancement, social equality, poverty reduction, and employment) and environmental protection (treatment of pollution, management of rational use of natural resources, and management of natural disaster risk). To achieve the goal of "sustainable development linked to growth model", TPCT focus on identifying resources, growth motives, difficulties and opportunities to implement appropriate solutions. The article uses data on TPCT's developmental realities in economic, social and environment in order to contribute some of the viewpoints related to challenges of sustainable development Mekong Delta.

Abstract: Plastic pollution has become a major global environmental problem. The amount of plastic waste, including microplastics discharged into the environment, is on the increase, causing harm to the environment, ecosystems, especially marine ecosystems, entering the food chain, and affecting human health. Recognizing the environmental risks of plastic waste, the State has issued many legal documents on plastic waste management such as the Law on Environmental Protection (2014, 2020); Law on Environmental Protection Tax 2010; National environmental protection strategy up to 2020, Vision 2030; National strategy on integrated solid waste management up to 2025, Vision 2050, among others. However, there are still many shortcomings to plastic waste management in Vietnam, e.g. there are no effective solutions in reducing, sorting, collecting, reusing, recycling and treating waste. More importantly, public awareness and understanding of microplastic pollution in Vietnam still need improving. Therefore, pollution caused by microplastics needs to be studied and evaluated in relation to its origin, current situation, impacts and management policies.

Abstract: The sediment is the final environment where heavy metals accumulate and directly impact the health of aquatic systems and humans.Therefore, the study was carried out to determine the total content and forms of heavy metals in the sediments at 13 locations in the Saigon River basin in rain and dry seasons of 2022. In addition, this research also assesses the pollution risk level and the correlation between heavy metals and physicochemical properties in the sediments. Chemical analysis was applied to determine the contributors of heavy metals while the geochemical calculation methods (hazard quotient (HQ), geo-accumulation index (Igeo), pollutant load index (PLI), individual contamination factors (ICF) and global contamination factors (GCF), risk assessment code (RAC)) were used to assess the pollution risk level in river sediments. The results show that Ag, Ba, Mn and Zn were metals with high pollution risks, especially in rain season. The results showed that the total concentration of heavy metals in sediments in rain season ranges from 109.92 to 4591.01 mg.kg–1 (Mn 〉 Zn 〉 Li 〉 Ba 〉 Ag 〉 Cr 〉 Cu 〉 Pb) and in dry season from 0 to 3117.8 mg.kg–1 (Mn 〉 Ag 〉 Zn 〉 Li 〉 Ba 〉 Cr 〉 Cu 〉 Pb). Applying the sequential extraction method, the metal forms of Ba, Cr, Cu and Li in the sediment samples are mainly residues (F5) (up to 76.53%), proving these elements dominated by natural sources. In contrast, the Mn extract composition was strongly influenced by human activity with exchange (F1) ( 〉 50%) and carbonate (F2) ( 〉 20%) components predominating. For Ag, Pb and Cu were mainly in organic form (F4). In dry season, the river sediments didn’t contain Pb because it didn’t carry away rainwater. In particular, Zn had a strong fluctuation between the extracted forms in rain and dry seasons, showing impacts from nature and humans sources. Besides, the statistical analysis results showed that pH affected Cu and Zn contents with a negative correlation, but did not detect the correlation between heavy metals and sand, clay, electrical conductivity (EC) in Saigon river sediments. The research results are foundational for the implementation and design of effective remediation strategies to prevent risks of river sediments degradation in the future.    

Abstract: Sustainable development is a global trend to build a prosperous society, especially to promote green growth towards ecological approach and based on sustainable use of natural resources in the context of climate change. This article, therefore, is an attempt to synthesize the sustainable development process in the world, from the initial awareness of the role of the environment in the development process in the 1980s, to the development of Agenda 21 in the 1990s, to develop and implement the 2030 agenda for sustainable development in the present time. The change in awareness and practice of sustainable development also demonstrates the trend of social-ecological transformation as a development trend and is an urgent requirement towards building a prosperous and sustainable society. Integrating sustainable development into international and national development policies can be considered as a form of promoting social-ecological transformation. The UNESCO’ system of Biosphere Reserves as a model for promoting sustainable development initiatives towards harmony between people and nature can be considered as a model of a social-ecological system. Vietnam as a country actively participating the sustainable development process in the world has made great efforts to build a prosperous and sustainable society.

Abstract: In recent years, electric two-wheeled vehicles (E2Ws) including electric bicycles and electric motorcycles have been used widely in Vietnam. Currently, the total number of E2Ws used is 3 million and with an average growth rate of 13.33% an estimated 6 million E2Ws will be used in 2024. E2Ws have been used widely among Vietnam’s youth. Based on the Theory of Planned Behavior (TPB) of Ajzen (2005, 2016) [1, 2], the main purpose of this research is to identify factors affecting the attitude to and intention of high school students in Hanoi city towards E2W usage and their affected level. The analytical results show that the attitude towards E2W usage is influenced respectively in descending order by (i) perceptions of economic benefit, (ii) usage convenience, (iii) friendly environmental awareness, (iv) stylish design. Usage intention towards E2Ws is determined respectively in descending order by (i) subjective norm, (ii) attitude toward E2W usage, (iii) the attraction of motorcycles. Based on the research results, some proposals for producers, authorities and policy-makers have been recommended.

Abstract: Today, the incidence of type 2 diabetes mellitus is increasing rapidly on global. This disease is shown with many complications that significantly affect public health. One of them is kidney complications, which have a high incidence among diabetic patients in Vietnam (25.6-33.1%). Age, history of hypertension, and dyslipidemia are considered to be the main risk factors for diabetic nephropathy. Thus, early detection of these factors for kidney damage is significant for diagnosing, monitoring, treatment, and prognosis of diabetic patients. Our descriptive, cross-sectional study conducting on 120 diabetic patients at E Hospital has observed that blood cholesterol levels, HbA1c levels were independently related to eGFR decline below 60 mL/min/1.73m2. From those data, an equation to predict the risk of diabetic kidney disease was estimated as p =  with k = Keyword: Type 2 diabetes, Diabetic nephropathy, Risk factor Today, the incidence of type 2 diabetes mellitus is increasing rapidly on global.

Abstract: COVID-19 is an infectious pandemic with far-reaching global consequences, affecting nearly every economic, cultural, social, and environmental area. The COVID-19 epidemic has wreaked havoc on the tourism sector, causing millions of people to lose their jobs and income all around the world. In order to assist the tourism industry to recover from the COVID-19 epidemic, Vietnam's tourism industry must acknowledge and re-evaluate tourism management and development. This research evaluated the economic, social, and environmental implications on the tourism industry worldwide and in Vietnam, as well as the Government of Vietnam's plans, policies, and strategies for safe adaptation and flexibility in reviving Vietnam's tourism business in the current circumstances. In addition, the report offers suggestions for reviving tourism.

Abstract: After 3 decades of sustainable development, Vietnam's development is still not sustainable, especially in terms of society and ecology, the economy is still a brown economy: low product quality, high consumption resources, causing environmental pollution, increasing greenhouse gas emissions – causing climate change, and other social issues. In the last 20 years, the Socio-Ecological theory has developed on a global scale and is widely applied in many fields for sustainable development. Currently, Vietnam is having many innovations in the direction of rapid and sustainable development, nature-based/harmonization development, and planning based on integrated ecological functions, etc. In this direction, the Center for Eco-Community Development (ECODE) conducted a case study based on the Socio-Ecological system approach in 3 coastal districts (Tien Hai district, Thai Binh province, Giao Thuy district, Nam Dinh province, and Cat Hai district, Hai Phong city), typical for the Red River Delta – one of the areas in Vietnam most vulnerable to climate change, and has obtained significant results about: i) Zoning of social - ecological functions; ii) Assessing the impacts of climate change and development resources/climate disaster resilience of sub-regions; and iii) propose solutions and models of climate-adaptive livelihoods based on ecosystems. The research results confirmed the role of ecological and social pillars and systemic, interdisciplinary, inter-regional, and ecosystem-based approaches are crucial in research for sustainable development in the global context.

Abstract: This paper studies the impact of weather on the number of under 15-year-old children hospitalized for pneumonia at Nghe An Pediatric Hospital using time series analysis of the data collected from 2014 to 2019. The study was carried out on 45,466 children, most of whom were under 5 years old. The study results show that there was a statistically significant inverse correlation between mean daily temperature and children’s hospitalization for pneumonia while humidity was positively correlated. Specifically, when the average daily temperature increased by 1 degree Celsius, the risk of hospitalization for pneumonia on the same day decreased by 1% (95% CI: 0.3 - 1.7%); whereas when the humidity increased, the risk of hospitalization increased by 14.4% (95% CI: 0.2 - 30.7%) on the day of hospitalization; risk increased by 16.5% (95% CI: 9.5 - 23.9%) one day before hospitalization; and risk increased by 15.2% (95% CI: 8.2 - 22.7%) two days before hospitalization. The results suggest that children are highly sensitive to weather factors, including temperature and humidity; therefore, it is necessary to take measures to protect children against changing weather.

Abstract: The objective of this paper is to incorporate risk in technical efficiency of listed ASEAN banks in a panel data framework for the period 2000 to 2015. Many researchers apply frontier estimation techniques such as data envelopment analysis (DEA) or stochastic frontier analysis (SFA) for their efficiency analysis. However, the banks’ complex production process requires more sophisticated techniques to account for internal structures within the black box so relying only traditional DEA or SFA is not adequate to deal with a multiple-input and multiple-output production technology. To incorporate undesirable outputs such as risk into inefficiency, we rely on the directional distance function (DDF). We employ the DDF under both parametric (SFA) and semi-parametric (SEMSFA) framework to make a comparison efficiency scores with risk adjusted in two scenarios. Our results suggest that risk is an important factor that bank managers should pay more focus to achieve long-term efficiency in ASEAN banks Keywords Bank efficiency; risk; directional distance function (DDF); semiparametric estimation of stochastic frontier models (SEMSFA) References ADB.
