Needs Analysis for University EFL Learners Majoring in Business English: A Scoping Review of Research and Practice

/in /by

In the context of international economic integration, Business English (BE) has played an increasingly significant role in business settings because BE is considered as a global communicative means, helping business transactions happen effectively among economies all over the world. In Vietnam, BE has been used more and more in trade transactions because Vietnam’s economy has explosively developed and Vietnam has expanded its international trade relations over the last ten years. The aim of the paper is to analyze and synthesize the needs analysis for EFL learners majoring in Business English globally. The results of the paper help higher education in Vietnam see the importance of needs analysis in ESP, needs analysis approaches, theoretical frameworks including target situation analysis (TSA), present situation analysis (PSA), learning situation analysis (LSA), then evaluate existing materials or coursebooks and adapt to create better universities’ curricula to meet the linguistic requirements in the workplaces in Vietnam.

Virtual Reality and Language Learning in Hospitality: An Investigation of Students’ Perceptions

/in /by

This research investigates the perceptions of students within the hospitality management program at Politeknik Negeri Lampung (Polinela) regarding the utilization of Virtual Reality (VR)-based learning in English for Hospitality, a specialized branch of English for Specific Purposes (ESP). With a qualitative approach, the study aims to uncover students’ perspectives on both the challenges encountered and the aspects appreciated in the context of VR-based language learning. The participants, comprising 23 individuals, responded to open-ended questions that aimed to delve into their experiences. The findings shed light on the feasibility and effectiveness of VR-based learning, with the majority of participants reporting minimal difficulties. Appreciation for the immersive learning experience, novelty, realism, and engagement factors were evident in their responses. This research contributes to the understanding of incorporating innovative technologies like VR in ESP contexts, highlighting the need to address technical challenges and optimize language support for a diverse learner population. The outcomes offer insights into the potential of VR-based learning to enhance language acquisition within specific vocational domains.

Theoretical Investigation on Highly Efficient Quinacridone Derivatives for Green Dopant OLEDs: A DFT Simulation

/in /by

The present computational work deals with the Quinacridone green dopant theoretical organic light emitting diode molecule has been carried out with density functional theory by using Gaussian09 package. All the quantum chemical calculations have been performed with HF, B3LYP and B3PW91 functional methods. The structural parameter, bond topological analysis and the corresponding electrostatic and transport properties of the OLED molecule has been calculated. The laplacian of electron density and bond ellipticity of molecule have been studied for various optimized methods. The atomic charges of the molecule for different optimized methods has been analysed with AIM, MPA and NPA charges. The HLG of the molecule are calculated from different optimized basis sets. The HF method value is 8.49 eV. The B3LYP and B3PW91 methods energy values are 3.13 eV and 3.12 eV respectively. These values are most equal to the energy gap obtained from density of states (DOS) spectrum. Hence, the ESP shows that expend of O-atoms and the charge accumulated through Quinacridone OLED molecule. The grateful Quinacridone green dopant derivative molecule is high quantum efficiency, longer lifetime and very useful to industrial organic pigment of these molecules.
