Abstract

Value-chain analyses from the production to consumption stages of custard apple (Annona squamosa) are discussed in this paper. Limitations to small landholders’ income through processes of the value chain and ways of improving the chain are described. Value-chain methodology was applied on custard apple chain which include of actors in the Tay Ninh province in South-East (SE) Vietnam to assess limitations that occurred from the production to the consumption stage, then to develop strategies and make recommendations to enhance profitability for farmers in the chain. The key findings of the custard apple value-chain analysis are: (a) Farmers and collectors/ wholesalers play a very important role in the chain; however, the processing factory is the primary factor that influences the whole custard apple chain; (b) Information about the market and prices governs farmers’ benefits and income; (c) Cooperation and coordination among farmers are the best means to reduce risk and loss if the price were to depreciate; (d) Interaction between custard apple producers and processing enterprises is necessary for a sustainable consumption system; and (e) Small-scale farmers are dependent upon the price of custard apple to mitigate risks.

Abstract

Online classes have become important for all subjects, including pronunciation, because of the rapid advancements in science and technology, particularly during the Covid-19 and post-Covid-19 pandemic. However, Vietnam has produced only a small number of research articles on the advantages and disadvantages of online English pronunciation classes. Therefore, this study was conducted with the aim of examining how English-majored students at Van Hien University perceived the advantages and disadvantages of learning pronunciation in MS Teams classes. The online survey method via Google form was used to collect data from students of three English pronunciation classes at the Faculty of Foreign Languages, Van Hien University and received 131 valid answer sheets, of which selecting five students continued to participate in semi-structured interviews via telephone. The findings demonstrate that the benefits of class recordings were undeniable. On the contrary, in addition to technical concerns, students encountered other obstacles, such as learning environment issues and lack of direct contact.

Abstract

The COVID-19 pandemic has caused universities to switch from traditional to online teaching and learning methods. As a result, social media has gradually become prominent as a teaching and learning resource in universities. Vietnamese universities and institutes recognize the potential of social media as a powerful tool for promotion and teaching. This study examines the positive impact of social media use on (a) enhancing teaching and learning in universities, (b) motivating and supporting students, and (c) developing community connections and assesses limitations of social networks in student learning within the university context. A qualitative approach with explicitly utilizing in-depth interviews was employed to collect data from ten lecturers and 19 students of all faculties of Van Hien University. The results of this case study have shown the positive effects of social media: enriching the teaching and learning experience in higher education by inspiring and supporting student as well as promoting community connections.

Abstract

The additive manufacturing basic techniques are ideal for swiftly fabricating items and evaluating their functionality, making them ideal for fast prototyping. Lighting, automotive parts, consumer electronics as well as on-demand items are among the industries where it is most extensively used. Currently, there are various types of additive manufacturing processes and also various research of future processes. Each of the processes will give different results for the user’s product as various parameters are involved. Therefore, the process selections can become problematic and challenging since additive manufacturing requires specification and knowledge in order to create a product with the most suitable additive manufacturing process. This research will serve the purpose of providing knowledge of the additive manufacturing process through an expert system. Expert systems have been widely used in providing solutions and to obtain the knowledge of certain information. This study will take on the challenge of gaining sufficient knowledge in additive manufacturing pertaining to its selections which will be presented through the set of an expert system in the software MATLAB that is being used. The methods of obtaining the information and providing solutions will be the key structure for this research. Therefore, the expected result for this research is to provide knowledge information on additive manufacturing process and also for its process selections that will be set up from the expert systems applications.
