INNOVATIONS OF VIETNAMESE PROCESSING AND MANUFACTURING ENTERPRISES IN THE CURRENT CONTEXT

New technologies create new ways of sourcing to meet the needs of previously traditional markets. The new demands for production and consumption and changing consumer expectations require businesses to change their production, business, design, marketing, and product distribution methods. With globalization taking place more and more strongly and the emergence of the 4.0 industrial revolution, innovation creates a competitive advantage for the country and businesses. In Vietnam, the processing and manufacturing industry has played an essential role in the economy's driving force. This article aims to assess the role and status of innovation for the survival and development of processing enterprises in the Covid–19 epidemic Keywords: Innovation, Technology, Competition, Processing, Manufacturing Enterprises

IMPROVING THE QUALITY OF FOREIGN LANGUAGE TEACHING STAFF AT THAI NGUYEN UNIVERSITY, VIETNAM IN THE CURRENT PHASE

Thai Nguyen University in Vietnam identifies improving the quality of the foreign language teaching staff as one of the priority tasks in the development strategy, training advanced and modern human resources to serve the economic, political, cultural, and social development needs of the midland and northern mountainous regions. Despite certain achievements, due to its unique characteristics, Thai Nguyen University is facing numerous challenges, especially in terms of the foreign language faculty, which is deficient and weak compared to the requirements. To meet the needs of training and cultivating foreign language teachers in the future, it is necessary to conduct research to accurately assess the current situation and propose solutions to improve the quality of the foreign language teaching staff.  Article visualizations

VARIATIONS IN FATTY ACID COMPOSITION OF TEA LEAVES (CAMELLIA SINENSIS) DUE TO PLUCKING TIME AND CULTIVARS

Fatty acid in green tea leaves is important flavour precursor which has a negative effect onaroma quality of black teas. In this study, fatty acid composition of three cultivars includingShan Chat Tien, Trung Du and PH11 plucked at different time was analyzed by GC-MS/MS.The results showed that C16:0, C18:2, C18:1, C18:0 and C18:3 were the most abundant fattyacids indentified in tea leaves. In particular, total saturated fatty acid in the tea leaves plucked inJune and September was higher than total unsaturated fatty acid and vice versa for sampleplucked in March. Principal component analysis (PCA) showed that fatty acid compositions insamples plucked in June of three cultivars were similar to each other and they were characterizedby C18:0, C22:0 and C20:0. The sample plucked in March and in September were characterizedby C18:1, C18:2 and C18:3, andC18:1, C16:1, C18:0, C14:1 and C14:0; respectively. Thesample plucked in March had the highest total fat content followed by sample plucked inSeptember and June. The results showed that plucking time and cultivars significantlyinfluenced the fatty acid composition of tea leaves

Morphology and Niche Partitioning of Fish Assemblage in the Tonle Sap Biosphere Reserve - a Case Study of the Prek Toal Core Area

A morphological approach provides vital information on community structure and ecological adjustments among different species that occupy in the same habitat. The coexistence of competing species in a diverse community results in niche partitioning in order to increase stabilization. Tonle Sap Biosphere Reserve, one of the world’s most productive inland wetlands is a tropical river ecosystem so dynamic that supports high biodiversity, especially fish population. This study tests the relationship between morphology and niche partitioning to understand the coexistence of diverse fish assemblages in the Tonle Sap Biosphere Reserve. By measuring 31 morphological variables and gathering ecological data of the collected 27 fish species, this study applies principal component analysis and cluster analysis to examine the influence of morphology on the ecological niches of the fish assemblage. The results of the study demonstrate that the diversifications in morphological characters directly determine niche partitioning of the fish assemblage in the Prek Toal core area of the Tonle Sap Biosphere Reserve
