A Prototype of Automated Chayote Peeling Machine

Fruit peeling seems a simple performance, but it is the consist of many elements such as the peeler, the way we grasp and move the blade and cutting speed, etc. - all these factors play a role, and interact with each other. This paper describes the prototype of a chayote peeling machine. The machine has been designed with a simple and low-cost approach. To improve chayote peeling rate and ensure pulp quality, a proposed structure was designed, manufactured and tested in laboratory. The experimental results are examined to demonstrate the efficiency of the peeling machine. It proves that the proposed machine could be widely applied in the fruit peeling technology

Reconceptualizing the Public Spaces of New Urban Areas in Hanoi: The End or the New of Public-Making?

Public spaces are designed and managed in many different ways. In Hanoi, after the Doi moi policy in 1986, the transfer of the public spaces creation at the neighborhood-level to the private sector has prospered nature of public and added a large amount of public space for the city, directly impacting on citizen's daily life, creating a new trend, new concept of public spaces. This article looks forward to understanding the public spaces-making and operating in KDTMs (Khu Do Thi Moi - new urban areas) in Hanoi to answer the question of whether ‘socialization’/privatization of these public spaces will put an end to the urban public or the new means of public-making trend. Based on the comparison and literature review of studies in the world on public spaces privatization with domestic studies to see the differences in the Vietnamese context leading to differences in definitions and roles and the concept of public spaces in KDTMs of Hanoi. Through adducing and analyzing practical cases, the article also mentions the trends, the issues, the ways and the technologies of public-making and public-spaces-making in KDTMs of Hanoi. Win/loss and the relationship of the three most important influential actors in this process (municipality, KDTM owners, inhabitants/citizens) is also considered to reconceptualize the public spaces of KDTMs in Hanoi

Bank BRI needs to evaluate customers who feel dissatisfied and disloyal

Evolution of Commercial Facilities in New Urban Areas of Hanoi: Potential of Sustainable Neighborhood-level Third Place Making

Shopping contributes largely to how people feel part of and enjoy KDTMs (Khu Do Thi Moi - new urban areas) - the carefully planned new sites, well provided with infrastructure, and very attractive of Hanoi in the market economy. Among the three facilities that are rated as most important by KDTM’s residents - education, health care, and shopping, the third is considered a pure civil space. This space clearly reflects the changes of politico-economic context and decision-making actors. Participation of the private sector in the newly formed market economy after a long period under State-run subvention and the consumerism entailed various ways to develop neighborhood-level commercial facilities. This paper aims to analyze and discuss on: firstly, the neighborhood-level commercial facilities have ‘promptly’ updated the changes in Vietnam's political-economic; secondly, the classify of KDTMs has resulted in a corresponding differentiation of commercial facilities according to the will of the project owners and the target consumer-resident; finally, facing the global ‘death’ of shopping malls, the KDTMs malls are trying to find themselves a new ‘vitality’: they are being ‘publicized’ to (re)create the third places in KDTM, that encourage social interaction in the limited spaces - intersperse public and private practices

UIT-ADrone: A Novel Drone Dataset for Traffic Anomaly Detection

Anomaly detection plays an increasingly important role in video surveillance and is one of the issues that have attracted various communities, such as computer vision, machine learning, and data mining in recent years. Moreover, drones equipped with cameras have quickly been deployed to a wide range of applications, starting from border security applications to street monitoring systems. However, there is a notable lack of adequate drone-based datasets available to detect unusual events in the urban traffic environment, especially in roundabouts, due to the density of interaction between road users and vehicles. To promote the development of anomalous event detection with drones in the complex traffic environment, we construct a novel large-scale drone dataset to detect anomalies involving realistic roundabouts in Vietnam, covering a large variety of anomalous events. Traffic at a total of three different roundabouts in Ho Chi Minh City was recorded with a camera-equipped drone. The resulting dataset contains 51 videos with total data traffic of nearly 6.5 h, captured across 206K frames with ten abnormal event types. Based on this dataset, we comprehensively evaluate the current state-of-the-art algorithms and what anomaly detection can do in drone-based video surveillance. This study presents a detailed description of the proposed UIT-ADrone dataset, along with information regarding data distribution, protocols for evaluation, baseline experimental results on our dataset, and other benchmark datasets, discussions, and paves the way for future work

Embedding Sustainable Consumption into Higher Education in Vietnam

Changing in the way that human produces and consumes are indispensable to achieve sustainable consumption. All of the countries in developed economies, economies in transition and developing economies should promote sustainable consumption. This will require larger changes in society. Higher education plays a vital role in promoting understanding, awareness of professors, staff members and students of sustainable consumption. Through higher education, these people would be positively change their mind about this issue. National Economics University (NEU) is one of the leading university in economics in Vietnam as a case study. Students graduated from the university will be future experts, leaders and businessmen. After graduation, as academic citizens with acquainted knowledge and skills, they will influence the economic and social changes though their business and private purchasing habits and decisions. Using data from the University, this paper will reveal the current landscape of sustainable consumption at National Economics University through the years. In order to embed this issues into education, the university should incorporate sustainable consumption into the curriculum, create and implement a sustainability plan and adjust teaching method to encourage students asking questions, analyzing, thinking critically and making decisions toward sustainable consumption.

Burden of diarrheal diseases from biogas wastewater exposure among smallholder farmers in Ha Nam province, Vietnam

Livestock production has developed rapidly in Vietnam in recent years, particularly at the small-scale which account for 65% of the total livestock production. Biogas systems are commonly used to treat livestock waste, however, the health risks from biogas wastewater exposure at smallholder farms are not yet well understood. A quantitative microbial risk assessment approach was applied to estimate the burden of diarrheal diseases from biogas wastewater exposure among 451 smallholder farmers using biogas systems in Ha Nam province. A total of 150 biogas wastewater samples were collected and analysed for E. coli, Giardia, and Cryptosporidium. The study showed that farmers faced diarrheal disease risks due to exposure to biogas wastewater at different exposure scenarios. The calculated annual risk of diarrheal disease by E. coli ranked from 0.15 to 0.21; by Giardia ranked from 0.022 to 0.095; and by Cryptosporidium ranked from 0.006 to 0.015. The estimated diarrheal diseases burden from pathogens in all exposure scenarios largely exceeded the reference level of health outcome target of 10-6DALYs loss per person per year recommended by WHO. The results suggest the importance in reducing concentrations of pathogens in biogas wastewater before use in the fields as a means for mitigating public health impacts
