Computer Assisted Language Learning (CALL) is not a trend; it has become practice in various contexts of language teaching and learning. However, CALL practices these days do not isolate the use of computers from the internet and various educational software and applications. This paper is to explore student perceptions on Smartclass software (SCS) design and its impacts on learning in interpreting classes of English and Korean major students at a university in Vietnam.

Salmonella can carry multiple antibiotic-resistant and metalresistant genes and transmit these genes among strains worldwide. This study examined seventy-five Salmonella isolates from small-scale chicken farms (chicken feces, bedding, feed, wild animals) in Vinh Long province for the presence and relation of antibiotic and metal-resistance genes in these strains.

A total of 319 nasal swab samples were collected to clarify the prevalence and antimicrobial susceptibility of E. coli in the respiratory tract of goats in Can Tho, Vietnam. It indicated that E. coli was detected at a relatively minor rate (8.46%), and their prevalence in male goats and dairy goats was higher than that in others.

The rate of antibiotic resistance in Helicobacter pylori (H.pylori) is increasing in Vietnam in recent years and has become a main challenge in the management of H. pylori infection. To determine the antibiogram of H.pylori strains isolated from a population in Central Vietnam to clarithromycin, levofloxacin by E-test and disk diffusion, compare two diffusion methods.

Wharton’s jelly-derived mesenchymal stem cells are highly homogeneous cells population, easily expanded, especially they can bring potential applications. However, their yield depends on the method of cells extraction conducted. Our research includes two purposes: 1/Procedure for isolating and differentiating mesenchymal stem cells from Wharton’s jelly, 2/Determining the main features of mesenchymal stem cells isolated from Wharton’s jelly.

Group B streptococcus (GBS) infections are still the leading cause of invasive infections in neonates, specically they also seriously cause mortality and morbidity with underlying diseases in adults. Curently, there are ten GBS serotypes (Ia, Ib, and II-IX) and the resistance characteristic of GBS is important to clinical treatment.

The focus of this thesis was to study the chemotaxonomic relationship of selected southern Australian marine brown algae of the genera Cystophora and Sargassum. Consequently, this resulted in the isolation and structure elucidation of six new terpenoids from two southern Australian marine brown algae Cystophora moniliformis and Sargassum fallax together with 10 previously reported natural products. As a result of the re-isolation of these known secondary metabolites, updated and complete structural characterisation data could be provided for the first time for 7 of these compounds.
