Speaking holds a particularly vital position in the communication process. For language-specialized students at the foundation level, developing speaking skills is of utmost importance. Among these, interactive methods employed in communicative tasks have a positive impact on the language acquisition process in general and speaking skills in particular. From the perspective of applied linguistics, this study employs scientific experimentation to demonstrate the constructive influence of interactive methods on enhancing vocabulary usage, grammatical structures, accurate language forms, attention engagement, retelling, and precise responses of students towards teaching Chinese speaking skills at the foundation level. The research also suggests the application of interactive methods in the development of Chinese speaking skills at the foundation level at Hung Vuong University

REALITY OF TRANS-DISCIPLINARY RESEARCH IMPLEMENTATION WITH “RESEARCH TEAM” APPROACH: AN INSIGHT INTO NEGATIVE FACTS AND FIGURES
Get PDFComplex problems in global development require cooperation among specialists from numerous backgrounds. Consequently, trans-disciplinary research seems to be appreciated due to its exploration of expertise far beyond the the specific boundary of an individual branch. This study seeks to identify negative aspects of the Research Team as an approach to the path of trans-disciplinary research. It was carried out at the National Economics University with 400 participants selected randomly from 20 faculties. Research methods covered questionnaires, semi-structured interviews, and documentary analysis in their institutional studies. It was revealed that despite the values of the Research Team from a theoretical perspective, this approach was not well adapted in reality. The relationship between academics and stakeholders was weak and the practical application of societal solutions was not largely implemented.Complex problems in global development require cooperation among specialists from numerous backgrounds.

PREPARATION OF CONDUCTIVE MEMBRANES BY CHEMICAL IN SITU POLYMERIZATION OF POLYPYRROLE ON CELLULOSE FIBERS
Get PDFThe development of flexible electronic devices, particularly flexible and bendable energy storage devices, has catalyzed significant interest in the research of flexible composite materials. In this study, conductive paper membranes were synthesized by polymerizing polypyrrole (PPy) on the surface of cellulose fibers. The cellulose material, derived from cardboard, underscores an eco-friendly approach to waste reduction and environmental protection. Characterization of the cellulose/PPy conductive membranes using Fourier-transform infrared spectroscopy (FT-IR), field-emission scanning electron microscopy (FE-SEM), and differential scanning calorimetry (DSC) confirmed the formation and uniform coverage of PPy on the cellulose surface. To enhance the uniformity of PPy polymerization on cellulose relative to previous studies, this work focuses on elucidating the formation and deposition of PPy particles on cellulose fibers, leading to the development of a homogeneous membrane. The membrane exhibited a peak electrical conductivity of 18.04 mS/cm at 0.1 mA, with conductivity increasing alongside PPy concentration, albeit at the expense of mechanical properties. Additionally, the membrane demonstrated charge storage capability, with specific capacitance values ranging from 22.5 to 50 pF/cm2 at a frequency of 1 kHz. The uniformity of PPy coverage on the cellulose surface was a crucial factor influencing the electrical properties of the composite membrane. This research highlights the significant potential of conductive membranes for application in flexible and bendable energy storage devices.The development of flexible electronic devices, particularly flexible and bendable energy storage devices, has catalyzed significant interest in the research of flexible composite materials.
