Isolation of carbapenem-resistant Enterobacteriaceae harbouring NDM-1, 4, 5, OXA48 and KPC from river fish in Vietnam

The spread of potentially life-threatening carbapenem-resistant bacteria is a major threat to public health. This study aimed to determine the prevalence of carbapenem-resistant Enterobacteriaceae in fishery products in Vietnam. A total of 103 river fish were purchased from retail outlets and supermarkets in Vietnam. The gut contents of fish were removed, mixed with buffered peptone water, and incubated for 24 h. The bacterial broth was spread onto CHROMagar™ ECC containing meropenem. Enterobacteriaceae were selected and antibiotic susceptibility testing was performed. Bacterial identification and genotyping were performed using 16S rRNA and multiplex PCR, respectively. Our results showed that 6.8% (7/103) of river fish were contaminated with carbapenem-resistant Escherichia coli harbouring NDM-1 or -5, and 8.7% (9/103) of the samples were contaminated with carbapenem-resistant Enterobacteriaceae harbouring NDM-1, -4, and OXA-48 genes. E. coli and Citrobacter freundii harbouring the NDM-1 encoding IncA/C plasmid were isolated from one fish sample; carbapenem-resistant E. coli harbouring CTX-M-15, NDM-5, and mcr-1 were also isolated. In conclusion, bacteria isolated from fishery products were found to carry the carbapenem resistance genes NDM, OXA-48, and KPC. As carbapenem-resistant bacteria are isolated from Vietnamese fishery foods at a rate of 6.8%, it is necessary to re-consider food hygiene rules.

The author used data survey from 225 people who are customers of commercial banks in Ho Chi Minh City (HCMC). The research methods used SPSS software for EFA and CFA analysis. The results of multivariable regression analysis determined 7 factors affecting intention to use e-banking services: perceived ease of use, expected effectiveness, and risk. transaction risk, bank branding, social influence, behavioral control and perceived preference. In which, the risk component in the transaction has the most important influence on the intention to use e-banking services, followed by the component of expected effectiveness, followed by the component of bank brand, followed by component of bank brand followed by the Social Influence component, then perceived ease of use, and finally behavioral control and perceived preference. The research results also serve as a basis for a survey for Vietnamese banks to promote using e-banking services by customers in developing electronic products in Vietnam.

An assessment of irrigated rice cultivation with different crop establishment practices in Vietnam

Overuse of seed and chemical inputs is a major constraint for sustainable rice production in Vietnam. In this study, two seasons of field trials were conducted to compare different crop establishment practices for rice production in the Mekong River Delta using environmental and economic sustainability performance indicators. The indicators including energy efficiency, agronomic use efficiency, net income, and greenhouse gas emissions (GHGEs) were quantified based on four treatments including manual broadcast-seeding, blower seeding, drum seeding, and mechanized transplanting. Across the four treatments, yields ranged from 7.3–7.5 Mg ha−1 and 6.2–6.8 Mg ha−1 in the Winter-Spring (WS) and Summer-Autumn (SA) seasons, respectively. In comparison with direct seeding methods, mechanized transplanting decreased the seed rate by 40%. It also led to a 30–40% reduction in pesticide use during the main crop season (WS). Mechanized transplanting required higher inputs, including machine depreciation and fuel consumption, but its net energy balance, net income and GHGE were at a similar level as the other non-mechanized planting practices. Mechanized transplanting is a technology package that should be promoted to improve the economic and environmental sustainability of lowland rice cultivation in the Mekong River Delta of Vietnam.

Adoption of Vietnamese Good Agricultural Practices (VietGAP) in Aquaculture: Evidence From Small-Scale Shrimp Farming

The increasing demand by international customers for high-quality shrimp products has led to the introduction of various certificates of traceability intended to validate quality products in Vietnam. The Vietnamese good agricultural practices (VietGAP), better known in aquaculture as the Vietnamese good aquaculture practices, has emerged as a reliable certificate for small-scale farmers and a prerequisite for international certification. This study investigates factors affecting applications for VietGAP by small-scale shrimp farmers in Vietnam. Cost-benefit analysis and binary logistic regression approaches were used to categorise shrimp farms with and without VietGAP certification. Findings indicated that while the adoption of VietGAP raised production costs by 14.5 %, it could increase net profit by up to 22 %. The increase in net profit is from increased productivity and antibiotics and chemical-free products in shrimp farming, helped fetch better prices. The results also revealed three factors that positively influenced the farmers’ decision to acquire VietGAP; education, farm size, and production system. Shrimp farmers with longer schooling years, larger farms, and those who possess cooperative/farming cluster membership are more likely to acquire VietGAP certification. The results imply that the VietGAP certification should be better promoted to cooperative production forms of farming, by strengthening the schooling year of farmers and increasing awareness of VietGAP certification to farmers who operate shrimp farms of 5,000–9,000 m2.

Agricultural products are one of the main export commodities of Vietnam. With the gradually increasing competition of this commodity in the world market, agricultural product manufacturers still depend a lot on the road transport method in transporting this type of goods while the railway has been ignored for too long. This research tried to investigate the factors and their extent that affect exporters’ decision to choose a rail transport mode. Additionally, environmental issues are being seriously considered in Vietnam. Environmental factors will also be included to understand its importance in the decision of exporters. The quantitative method is applied in the research and relevant literature reviews are taken as references to conduct the survey sent out to agricultural exporters in Vietnam for data analysis. The binary logistic regression model was applied to the study of 138 samples in Vietnam and the investigation as well as outcomes of the research would generate a practical model to predict the behaviors of agricultural exporters in making decision of using railway in Vietnam.

The capability of terrestrial laser scanning for monitoring the displacement of high-rise buildings

Recently, terrestrial laser scanner (TLS) has been increasingly used to monitor ofdisplacement of high-rise buildings. The main advantages of this technique are time-saving, higherpoint density, and higher accuracy in comparison with GPS and conventional methods. While TLS isordinary worldwide, there has been no study of the capability of TLS in monitoring the displacement ofhigh-rise buildings yet in Vietnam. The paper's goal is to build a procedure for displacement monitoringof high-rise buildings and assess the accuracy of TLS in this application. In the experiments, a scannedboard with a 60 cm x 60 cm mounted on a moveable monument system is scanned by Faro Focus3DX130. A monitoring procedure using TLS is proposed, including three main stages: site investigation,data acquisition and processing, and displacement determination by the Cloud-to-Cloud method (C2C).As a result, the displacement of the scanned object between epochs is computed. In order to evaluate theaccuracy, the estimated displacement using TLS is compared with the real displacement. The accuracydepends on scanning geometry, surface property, and point density conditions. Our results show that theaccuracy of the estimated displacement is within ± 2 mm for buildings lower than 50 m of height. Thus,TLS completely meets the accuracy requirements of monitoring displacement in the Vietnam Standardsof Engineering Surveying. With such outstanding performance, our workflow of using TLS could beapplied to monitor the displacement of high-rise buildings in the reality of geodetic production inVietnam.

Curcumin-removed turmeric oleoresin nano-emulsion as a novel botanical fungicide to control anthracnose (Colletotrichum gloeosporioides) in litchi

Abstract During curcumin production in Vietnam, curcumin-removed turmeric oleoresin (CRTO) has been considered as a by-product. It costs to treat the by-product to prevent environmental pollution. In this study, the by-product was utilized as an active ingredient for preparing a botanical fungicide-based nano-emulsion and evaluated for its in vitro and in vivo control efficacy against Colletotrichum gloeosporioides, a causal agent of anthracnose of litchi, in the laboratory as well as a field trial. The nano-emulsion is colloidally stable and uniform with particle sizes of 95–250 nm. CRTO nano-emulsion significantly affected various Colletotrichum species. Notably, this nano-emulsion showed potent inhibition for the mycelial growth of C. gloeosporioides and solidly suppressed the development of anthracnose on litchi fruits. In the in vitro inhibition test, the equivalent half-maximal inhibitory concentration of CRTO in nano-formulation was 0.11 mg·mL−1, which was 3.0× and 6.1× lower than IC50 values of CRTO alone (0.33 mg·mL−1) and a mixture of curcuminoids (0.48 mg·mL−1), respectively. In the field trial, the litchi anthracnose infection was effectively controlled by nano-formulation. These results suggest that CRTO nano-emulsion could be used as an alternative to harmful synthetic fungicides to control anthracnose on litchi fruits.

Land Suitability Modeling For Ricecrop Based On An Integrated Multi-Criteria Decision Making In Quang Tri Province Of Vietnam

The present study was aimed to determine the potential cultivated lands for rice crop production in Vietnam. Analytic Hierarchy Process (AHP) and the Technique for Order of Preference by Similarity to Ideal Solution (TQPSIS) were employed in order to analyze the structure of an ideal solution in agriculture that focuses mainly on environmental, economic, and social sustainability. A final ranking of alternative development solutions was also accomplished. Three major factors were taken into consideration during the process, including the economics, social concerns, and the environment, in order to develop a sustainable plan for rice and other grain crops in the future. The obtained results demonstrate that the area under investigation in Quang Tri province, which encompasses 192.49 km2 of land area, was extremely conducive to growing rice crops, with the majority of the arable lands suitable for cultivating rice varieties concentrated in Trieu Long District (63.14 km2) and Hai Lang District (56.87 km2). The main findings of the present work indicated that, it can link decision makers with the influencing variables of rice crop growing utilizing a hybrid method that can be successfully used based on GIS technique. To expand production, chemical soil characteristics and agricultural development strategies should be investigated further, particularly in the studied areas with greater success potential.

Adoption of contract farming for managing agricultural risks: a case study in rice production in the Mekong Delta, Vietnam

Purpose Farmers' risk attitudes and risk perceptions play an essential role in shaping risk management strategies to address risks and uncertainties. Contract farming is considered as one of the feasible approaches to tackle farmers' concerns. However, risk perspectives under various categories have not been included in studies on farmers' preferences for contract farming in the literature, especially in Vietnam. This study aims to determine factors affecting farmers' choices of different contract farming practices. Design/methodology/approach The explanatory factor analysis (EFA) and multinomial logit model (MNL) were applied to explore the impacts of risk perspectives on farmers' preferences for contract farming. Data have been collected from 211 rice farmers in An Giang Province, “the rice bowl” of the Mekong Delta, Vietnam. Findings The study found that farm size, cooperatives, extension, market access and trust have significantly impacted on contract participation while a delay payment was a barrier for farmers' motivation to opt for the contract. Farmers' contract choices were also influenced by their risk attitudes and perceptions under different risk dimensions. The financial, policy and human risk-averse behavior predisposed farmers to single out the full contract while the policy and human risk-loving and production, market and finance risk-averse respondents were in favor of the marketing contract. Moreover, the findings indicated that the more farmers concerned about risk of weather and market, the more choices for the full contract, whereas the risk perceptions of weather and policy encouraged farmers to use the limited contract. By contrast, farmers who perceived the impacts of risk of diseases/pests and human were likely to adopt the marketing contract. Research limitations/implications This study just focuses on collecting data from farmers’ perspective. Future studies involving stakeholders such as enterprises and policy makers are strongly recommended so as to design suitable contracts and enforce contract schemes effectively in Vietnam. Originality/value The findings also contribute to the literature on different types of contracts and the multidimensional aspect of risk for rice production in Vietnam.

The impact of cooperative participation on income: the case of vegetable production in Vietnam

PurposeThe demand for clean vegetables has rapidly increased, many farmers gradually turn to vegetable cultivation to increase income; therefore, agricultural cooperative mobilized farmers group to facilitate them access to technical training and enhance compliance with the Vietnamese Good Agricultural Practices (VietGAP) standards. The purpose of this paper is to evaluate the impacts of the participation on farmer’s income as well as the major factors that affect the participation in cooperatives by the vegetable farmers in Vietnam.Design/methodology/approachThe study used primary data collected from vegetable farmers in Vietnam. This study utilized propensity score matching to avoid initial selection bias. The differences between participants and nonparticipants will be adjusted by matching each membership individual to a nonmember based on similar observable characteristics by summarizing the conditional probability of a member given pretreatment characteristics.FindingsThis study demonstrates that participation in cooperatives is significantly affected by ethnicity, age of household head, labor involving vegetable production and extension service access. The results of this study also confirm that agricultural cooperatives have positive effects on member farmers to enhance income and that participants – on average – have a higher income than nonparticipants.Research limitations/implicationsThe method cannot rule out the possibility of selection bias due to unobserved differences between participants and even an appropriate comparison group.Originality/valueThis study contributes to an improved understanding about impacts of cooperatives on farmers’ income in developing and emerging economies. Moreover, research also upgrades knowledge regarding the effectiveness of agricultural cooperatives in Vietnam, as well as guides policymakers in supporting the cooperatives in expanding the market and other necessary changes.

Hallyu (the ”Korean Wave”) in Vietnam

By now popular culture of South Korea is widespread not only across Asia, but also worldwide. However, the problem of the features of Hallyu content reception in Asia lacks research, what stipulates for actuality of this work. The task of the research is to reveal the specific character of the reception of “the Korean wave” products in Vietnam.The research has shown that in the SRV “the Korean wave” reception process is divided into four stages, the reception took place unimpeded on each of them. The modes of reception of Hallyu products in Vietnam comprise re-makes of Korean films and “trendy dramas”, joint issue of musical compositions with the participation of Korean singers, as well as cooperation in filmmaking. In the SRV cultural diffusion is not deep, as in fact, the initiative almost entirely belongs to the Korean side. Despite public displeasure with “the Korean wave” content, which is a real conflict of cultural interests, Vietnamese authorities do not undertake any limitations against Hallyu and do not strive to slow the reception artificially, while economical advantage of the cooperation with the Korean side is very high, and the Vietnamese entertainment industry can evolve on the investments of large South Korean companies.

Efficiency of Bollinger Bands in Forward Operations for Agricultural Products in Vietnam

U
 Using primary data collected from in-depth interviews with 11 practical experts who have been working in the commodity industry for 7 years on average and using the Bollinger Bands tool for 3 years at least, the article shows that Bollinger Bands' signs on price forecasts or making decisions to buy or sell in the future trading of agricultural products in Vietnam are highly appreciated because of their accuracy. In addition, by using the Analytical Hierarchy Process (AHP) approach, the research indicates that there is no big difference in the effectiveness of Bollinger Bands’ application in future transactions for coffee, corn, wheat, soybean and soybean oil. However, applying Bollinger Bands in coffee futures’ trading is the most effective. In addition, the study also emphasizes the combination of Bollinger Bands with other technical analysis tools such as RSI, MACD, Fibonacci, Ichimoku, and CCI, to improve transaction efficiency.

Human capital and productivity growth in agriculture in Vietnam

For a country that is in the process of transforming its agricultural model for development like Vietnam, human capital development is one of the most important keys to ensure the sustainable of economy. In order improve agricultural productivity, it is needed to increase the level of human capital of the agrarian population. This study examines the relationship between human capital and labor productivity in the 1997 - 2018 period of Vietnam. This study employs a quantitative approach, using the endogenous growth model with the Cobb-Douglas production function to analyze the factor’s contribution to Agriculture labor productivity. The result showed that human capital development has a significant impact on agricultural productivity in Vietnam. The result also showed that there exists a U-shaped quadratic relationship between trade openness and agricultural output. The findings also showed that the contribution rate of human capital in labor productivity growth is low, while capital investment does not reflect changes in labor productivity. Therefore, in order for human capital to become one of the important factors to promote Agriculture labor productivity in the future, Vietnam needs to raise awareness of the role of human capital and to focus on developing human resources as a tool for improving productivity of agriculture, to transform the growth model from width to depth. It should also be essential to move towards developing hi-tech agriculture with high productivity in the future.

Factors Affecting Organic Fertilizer Adoption in Rice Production in Vietnam

The adoption of organic fertilizers is one of the measures of sustainable agricultural production in Vietnam. This research evaluates the effectiveness of organic fertilizer application and the factors affecting adoption of organic fertilizers in rice production. The data of 3,972 rice farmers from the 2014 Vietnam Household Living Standards Survey dataset are used in the analysis. The results show that yield, revenue, and cost of rice production for farmers using only inorganic fertilizers are greater than those forf farmers applying organic fertilizers. However, there is a consistent profit between the two groups of farmers. Use of organic fertilizers improves the financial efficiency of rice production for farmers. The amount of inorganic fertilizers required decreases when farmers apply organic fertilizers. Farmers who are Kinh people, have loans for rice production, or have large land areas tend to use less amount of organic fertilizers. Meanwhile, farmers with higher education, who join the Farmer's Association, or have more household members, are more likely to use organic fertilizers for rice production. This study implies that farmers should apply organic fertilizers to increase the financial efficiency and sustainability of rice production. The government needs to design policies to motivate the production and utilization of organic fertilizers.

The Impact of Social Network Advertisements on Consumers’ Purchasing of Jewelry Products in Vietnam

This study examines the impacts of social media advertisements on consumers' behaviors shopping for jewelry products in Vietnam.
