ISOLATION AND SELECTION OF AFLATOXINS PRODUCING ASPERGILLUS FLAVUS FROM PEANUT

Aspergillus flavus is known as the main producer of carcinogenic aflatoxins. The presence of this fungus and aflatoxins is an important impactson food safety, human and animal health. Peanut is one of the most important crops in Vietnam and  is suitable to substrate for aflatoxins producing fungus growth. The isolation and identification of Aspergillus flavus species from peanut is an initial step for further study in Aflatoxins contamination control in peanut. 28 peanut samples selected in Luc Nam district - Bac Giang province were used for fungus isolation. The isolated fungus were purified, conducted DNA extract, amplified PCR products then performed sequencing ITS gene and used BLAST software to check alignment to identification the strains. As the result, 4 strains alignedwith Aspergillus flavus strains from National Center for Biology Information - United Nation such as: TUHT115, KP214054.1, MTCC 8654, ZJ4-A. Those strains were checked and confirmed the aflatoxins production in peanut samples

On Building a Community to Exchange and Share Sustainable Fashion Applications

Sustainable development is a standard plan for peace and prosperity for people and the planet, now and in the future, set forth by the 2030 Agenda for Sustainable Development, which was adopted by all United Nations member states and agreed to in 2015. The Sustainable Development Goals (SDGs) are an urgent call to action for all developed and developing countries in relation to global cooperation. Many factors cause environmental pollution, but the fashion industry is considered by the United Nations Conference on Trade and Development (UNCTAD) as the second most polluting industry in the world. It accounts for 10% of global carbon emissions due to the energy used in production, manufacturing, and transportation. In particular, the factors that strongly affect the environment in the fashion industry are the textile materials, the fabric dyeing industry, and the rapid development of fast fashion. The data was collected through an online survey of 101 fashion consumers and interviews with nine target audiences who need to buy and sell used clothes or are interested in buying and selling used clothes or sustainable fashion. Sustainable design is not a new concept, but it is still quite strange to the Vietnamese. Consumer ignorance about sustainable consumption and the harmful effects of the fashion industry on planet Earth is a big reason why consumers constantly plunge into the shopping vortex. The problem of wasteful and unsustainable fashion consumption is a big global problem at a time when the fashion industry is gradually emerging into the sustainable fashion movement. This is an opportunity to build a community by connecting consumers through their essential needs, helping them raise awareness, change their behavior, and make each individual part of a sustainable fashion community. They are thus contributing to sustainable development in the future. Keywords: SDGs, sustainable fashion, sustainable consumption, communit

Building Comprehensive Sex Education Plans for Teenagers: Groundwork-Based Research Design Application

Although sexual education is an important part of a child’s education and upbringing, in Vietnam, sex education is not an official subject in school, and young people’s awareness of Comprehensive Sex Education (CSE) is still limited. While sex education at school is necessary, it is not the only way nor sufficient enough to change teenage sexual behavior. A parent’s role could involve communicating about values, providing a positive family environment, and monitoring their children’s behavior. This topic explores the awareness of teenagers about CSE and the availability of teaching CSE in Vietnamese schools and families. Data was collected via an online survey of 89 teenagers and 119 parents whose children are teenagers. The findings revealed that the target group is not fully aware of CSE and in particular, they also feel the importance of the family in this regard but are afraid to share gender issues with their parents and tend to find information on their own through the internet.

ENGLISH TEACHERS’ SATISFACTION WITH THE QUALITY OF GENERAL ENGLISH PROFICIENCY TRAINING PROGRAM: THE CASE OF THE MEKONG DELTA, VIETNAM

Many policy changes in teaching and learning English in Vietnam have been implemented. To make those changes successful, the quality of English teachers is paid remarkable attention to by stakeholders. In particular, the quality of their teaching is said to be the determining factor in the success or failure of the changes. Since then, many professional development programs for English teachers have been implemented in Vietnam. This research explores Vietnamese teachers’ satisfaction with the effectiveness of a large-scale general English proficiency training program provided by MOET’s National Foreign Languages Project for school teachers in the Mekong Delta. Employing questionnaires with 174 school teachers in the Mekong Delta, the study sheds light on the main factors that these teachers perceive as crucial factors that influence the quality of the training program and their satisfaction. Findings from the survey reveal that the teachers were highly satisfied with the training program, and the critical factors impacting the training effectiveness included training materials, training duration, teaching and learning facilities, qualified trainers, and support from management. These findings provide a solid foundation for proposing an efficient model training program to effectively support English language teachers in the Mekong Delta to accomplish the required English proficiency level.  Article visualizations

Effects of different nutrient solutions on growth and flower quality of gerbera (Gerbera jamesonii) grown in hydroponic close system

The nutrient solution is the decisive factor for the growth and development of hydroponic plants. This study was conducted to determine the effect of five nutrient solutions, namely, Hoagland, Knop, Hydro Umat F, BKFAST, and Bio-Life, on the growth and development of gerbera (Gerbera jamesonii) in the hydroponic system. The results show that Hydro Umat F is the most suitable solution for planting gerbera in terms of plant height, number of leaves, leaf size, and root volume. In addition, the flower yield of the gerbera plants nourished on Hydro Umat F is also the highest, with 8.7 flowers per plant after five months in the hydroponic system. The flowers have a diameter of 9.8 cm and natural durability of 19.67 days. Meanwhile, gerbera plants stop growing after 15 days in the Bio-Life solution and 30 days in the Knop solution

The impact of the COVID-19 pandemic on the stressful relationship between parents and children

The stressful relationship between children and parents is the pain both go through when they find themselves unable to cope as a parent or a child. In order to find out the status, causes, and impacts of the COVID-19 pandemic and suggest some solutions to reduce stress between parents and children, we surveyed the impact of the COVID-19 pandemic on stressful relationships between parents and children at high school age in Da Nang city. The findings of a survey conducted on 550 randomly selected parents and 550 high school students using the Perceived Stress Scale reveal a high rate of tension between parents and their children, particularly up to 51.1% and 38.5%, respectively. In reality, many factors are affecting the stressful relationship between parents and their children at this age, in which psychological fear about health; social distancing policy; closed schools; students staying at home 24 hours a day and learning online; the disruption in children's daily routine; excessive use of electronic devices are major causes of stress in the relationship between parents and their children. From this practice, our research team has proposed such solutions as participating in creative activities and consulting the handbook instructing parents' behaviour rules toward children and vice versa, designing extra-curricular activities, and organizing training courses on life values for both parents and children to increase happiness and reduce stress in the parent-child relationship

Equity in Tax Law: Vietnam Case Study

One of the prime principles in the optimal tax system of countries is fairness. Equity in tax law originates from two points of view: fairness on the principle of benefits (from which taxpayers take away from society) and fairness on the principle of the ability to pay taxes (income). According to economist Adam Smith, "taxes are seen as the basis of economic institutions, which can cause economic instability when there is a lack of transparency and clarity". Therefore,  fairness in tax law formulation at different stages of development of each country is considered a complete principle associated with countries' economic, social and political conditions in each period. The scope of this article, based on research regarding the history of construction and development of tax law in Vietnam through the analysis of fairness in tax obligations, tax exemption, tax administration, tax fairness and tax accountability. Proposing solutions towards ensuring fairness in completing the legal tax system in Vietnam
