Abstract: Urban agriculture is a highly concerned issue during the period of rapid urbanization in Vietnam. Research aims to propose a cultivation process for cultivating oyster mushrooms, utilizing coffee grounds from coffee businesses as a resource. This approach promotes circular economy principles, generating economic benefits for households while protecting the environment and being suitable for urban areas. The study conducted experiments on grey oyster mushrooms using different mixtures of coffee grounds and rubber wood sawdust at the following ratios: 0%, 25%, 50%, 75%, and 100% coffee grounds/rubber wood sawdust, filled into bags with a weight of 1.2kg. The research results showed that disease infection rates were mild in the 0% and 25% mixture ratios, while the remaining ratios exhibited moderate to severe infection levels. The highest mushroom yield was observed in the mixture ratio of 25% coffee grounds, with an average number of mushroom ears per bag reaching 29.7grams/bag, the dry weight is 63.8 grams/bag, with an average size ranging from 3 to 14 cm and a moisture content of 79.5%. The fastest colonization speed on the substrate is achieved by 25%, 50% coffee grounds blend, which fully colonizes the bag in a period of 25 to 35 days, the shortest time compared to the 75% and 100% coffee grounds blends, which take 40 to 45 days. The experimental results show that the 25% coffee grounds: 75% rubber sawdust blend is suitable for urban mushroom cultivation models and can be expanded on a large-scale farm, contributing to minimizing environmental pollution, utilizing limited urban land area, and providing high economic efficiency.

ABSTRACT The world’s financial market has recently suffered from many fluctuations due to currency changes and the crisis, especially after the bank collapsed in the United States, cryptocurrencies have become one of the leading choices made by many investors in the world. It is undoubted that the development of cryptocurrency is an inevitable trend in society's future. In that context, updating knowledge about the general development trend of the financial market as well as about the cryptocurrency system is indispensable for everyone, especially young people - the generation that holds the global economy's future. Therefore, it is urgent to present and educate the cryptocurrency framework to college students. If there is no action taken, economics instructors will run the risk their students are left back in this flourishing and endlessly changeable economy. To start the educational story about cryptocurrency, it is crucial to define the measurements of students' awareness about the medium ahead of teaching-related materials. The data of the study are collected from 355 survey samples conducted by students in Ho Chi Minh City. The survey consists of 15 questions using various scales, designed by the researchers and using MS Excel 2016 for quantitative analysis, including using percentages, frequencies. The results show that the students' awareness is still low despite the significance of knowing about cryptocurrency. But they are also gradually realizing the necessity of things and are willing to improve their own knowledge of this aspect. Keywords: education, cryptocurrencies, students’ perceptions

Vietnam's economy is operated to serve more than ninety million people so this is a very vivid picture. The large population brings many advantages to the food production sector in general and the production of fresh noodles in particular. Fresh vermicelli is the raw material for processing many dishes of the Vietnamese people for a long time, that's why there are many Vietnamese dishes with indispensable ingredients, which as Noodles in the national culinary books. Vietnam. The production of fresh vermicelli with the main ingredient is fermented and shaped rice with simple steps, but hidden inside there are environmental issues that need to be considered. The production and business associated with environmental protection are the responsibility of most enterprises and production facilities in Vietnam. The fresh noodle food production industry is no exception. Instead of learning about the aspects that affect the environment in the traditional way of collecting information, analyzing, and evaluating the current situation, this time the research team looked at understanding the causes of environmental pollution in terms of consumption. ISO 14001 international standard. ISO 14001 Environmental Management System is an international standard that helps businesses and establishments identify the important role of the environment as well as the risks brought by the environment, thereby realizing the environment as an activity of the Organization. In this standard, the commitment to prevent environmental pollution is a mandatory condition, so determining the environmental aspects to overcome the impacts is a key element of the standard. If a business achieves ISO 14001 Certification, it will have a very good effect in promoting the corporate image of being responsible for the environment and the community.

Binh Duong, a dynamic province in the Southern Key Economic Region in Vietnam, has a fast growing economy and strong economic restructuring towards industrialization and modernization, have affected many aspects of economy, culture, society and environment. This study analyzes the influence of economic restructuring on urban development in Binh Duong province by utilizing the time series data throughout 2000 - 2020 and the household interview method of the topic "Urbanization and its effects on land use restructuring in Binh Duong province" shows the shift of occupations from agriculture to non-agriculture. The research results show that economic restructuring contributes to promoting economic and social development in general and expanding the urban network of Binh Duong province in particular, but it has some limitations in the process of development. Therefore, Binh Duong wants to successfully integrate into the world economy and develop urban areas towards sustainability (by 2030), it must have specific, scientific and objective analysis and evaluation on the success and limitations of the economic restructuring process and its impact on the urban system in recent times. The research results also have a scientific basis for proposing appropriate and effective solutions and policies to successfully implement the goals and orientations of economic restructuring and urban development that Binh Duong has been approved.

Binh Duong is a province in the Southeast region. It has a long history of growth and numerous noteworthy historical and cultural values. This paper provides a summary of the cultural and historical significance of Binh Duong Province during the prehistoric, land exploration, and settlement phases. It discusses population, administrative structure, social structure, economic traits (agriculture, handicrafts, commerce), and social culture throughout the various eras (prehistory, settlement phase, Nguyen dynasty). The findings demonstrate that Binh Duong not only has a rich history with numerous economic and cultural assets, but also point to possible research avenues for safeguarding and advancing moral principles in the construction and development of Binh Duong province today and in the future.

Recognized as a smart city, Binh Duong's smart city development strategy also includes the development of automated agriculture, typically large-scale livestock farming. A sustainable urban development will not be able to ignore the factor of providing food for urban and regional people. Phu Giao district - Binh Duong province is one of the leading districts in livestock farming, especially concentrated pig farming. The agricultural industry, pigs breeding, is one of the strengths of the district, besides the cultivation of short and long-term industrial crops such as rubber, cashew, Ho Tieu... Livestock is a very old profession of the Vietnamese people in Phu Giao district as well as in Binh Duong province. The contribution of livestock production to the socio-economic face of the district cannot be denied. However, animal husbandry activities, besides the economic values, also cause some consequences to the natural environment such as soil and water pollution, noise, odors in the air, etc. Hence, we decided to do the research of "Application of ISO 14001:2015 international standards in determination of environmental aspects at market hog farm with semiautomatic technology farm size 12,000 pigs per year in Phu Giao district, Binh Duong province" (TCVN ISO, 2015). This is a large-scale pig farm with modern semi-automatic technology equipment. We expect to find out environmental issues in the most detailed and specific way so that the owner can overcome the above environmental problems, rest assured to raise livestock and develop more expansion later. We conducted a review of the areas on the farm, evaluated the activities in each area, from which we found out the environmental problems through the material flow diagram (Phạm Thị Hồng Cẩm, 2020). Next, through the multi-criteria method (Phạm Thị Hồng Cẩm, 2020) we calculated the score and found the most significant environmental aspects (most environmental risk). The research results will be a general picture to provide farm owners with an intuitive and easy-to-understand view for suitable solutions. Developing farm economy along with environmental protection towards sustainable development of livestock agriculture.

The paper demonstrates the role of globalization and localization in the process of Vietnam’s interaction and integration with other cultures, causing changes in Vietnamese language. Globalization is defined as the free movement of goods, services and people of the worldwide scope across the borders of countries, resulted from the opening up of the global economy and advances of technologies. The increasing interconnectedness and integration of the economies of the world furnish more influx of information among countries which do not have anything in common and Internet and social media well contribute to such spread. Not only the pros but the cons of globalization are used to explain the part of localization as the entire process of adapting a product or content to a specific location or market. The paper indicates localization as the Vietnamese people’s endeavor to adapt Vietnamese language to the world while protecting and enhancing the national characters. The differences between localization and globalization are analyzed to demonstrate the value and requirements of localization in the present time. The influences of Sino-Vietnamese and French language are also found out as evidences of the phenomena. The changes of Vietnamese language from globalization and localization are illustrated with devices, ideas and images referring to the objects, actions or ideas.
