This research aims to analyse consumers’ (Millennials and Gen Z) luxury consumption behaviour by focusing on the intrinsic and extrinsic motivations that drive consumption of luxury goods. Then, the study investigates whether they prefer to purchase offline or online for luxury goods. Lastly, it analyses which media most influences individuals when it comes to luxury consumption. An online survey is developed and distributed to Millennials and Gen Z. A first round of data collection took place in 2022 and a second round of data collection will take place at the beginning of 2024. Initial findings show that consumers are driven by intrinsic rather than extrinsic motivations when purchasing and who influences more when buying luxury online. Furthermore, it emerges that consumers prefer to shop offline, highlighting the importance of physical stores.

The study investigated the influence of website features on the purchase intention of online fashion among Generation Z consumers in South Africa. This topic has received increasing attention against the backdrop of the rapidly growing ‘Digital Generation’, or ‘Millennial consumers’, who are one of the most tech-savvy generations. Despite the benefits that online shopping offers to both the business and the consumer, the act of buying clothes online has presented some challenges to customers. This study therefore aims to gather further insight in an attempt to provide fashion businesses with guidance to better succeed in encouraging customers to shop online. This study selected two visual elements (website aesthetics and product presentation) and two functional website features (website navigation, and security and privacy) and social norms, the test the effect they have on perceived ease of use, attitude and intention to purchase clothing online. The proposed conceptual model tested seven hypotheses of which four were supported. By means of an empirical study, 166 online surveys were collected from individuals within the Generation Z cohort and the analysis was done using SPSS27 by running multiple regression analysis to test the relationships between the variables. The results from this study provide global and local fashion brands with valuable insight into the consumption habits of young consumers in an emerging economy, and factors that drive online fashion consumption.

This study analyzed differences in the purchase satisfaction and repurchase intention of customers who buy clothing products from online platforms. The participants were teenage individuals to those in their 50s residing in Busan, Ulsan, and Gyeongsangnam-do. The data were examined via factor analysis, a t-test, Analysis of variance(ANOVA), Duncan’s multiple range test, two-way ANOVA, and linear regression analysis. The factors for satisfaction with clothing products from online platforms were wearing comfort and quality, design, and price and purchase convenience. The findings revealed that purchase satisfaction based on these factors significantly varied among the participants depending on marital status, age, and occupation. Satisfaction with wearing comfort, quality, and design differed by gender. Satisfaction with wearing comfort, quality, and price and purchase convenience varied by type of purchase and type of online platforms. The interaction effects among the variables that affected purchase satisfaction were as follows. The interaction effects among the variables for wearing comfort and quality showed significant interactions between gender and type of purchase and between occupation and type of online platforms. Those for design showed significant interactions between marital status and age, between age and occupation, and so on. The interaction effects for price and purchase convenience showed significant interactions between marital status and gender and between age and occupation. The results on repurchase intention showed significant differences in such intention by marital status, age, and occupation. Repurchase intention was influenced by wearing comfort and quality, price and purchase convenience, design, and age.

This paper presents data capturing Korean university students’ familiarity with English online acronyms, examines factors that may predict this familiarity, and presents an explicit instruction intervention involving vocabulary knowledge of online acronyms. The Vocabulary Size Test (VST) measured stude nts’ vocabulary size, while a self-report survey measured social media engagement and the percentage of engagement that occurred in English. The Vocabulary Knowledge Scale (VKS) measured initial familiarity and gains in vocabulary knowledge. The results suggest that English learners in Korean universities are not well-acquainted with English online acronyms, but that receptive vocabulary size and English-language social media engagement may offer some predictive power regarding their level of familiarity. An explicit treatment of acronym expansions and their uses resulted in a significant and robust gain in vocabulary knowledge, suggesting that explicit instruction of online acronyms may improve digital literacy and comprehension of computer-mediated communication (CMC) more effectively than simply relying on incidental gains through repeat exposures over time.

This study addresses the scarcity of research examining technology’s impact on learners of English as a foreign language in English for specific purposes (ESP) courses within English-medium instruction (EMI) programs. Focusing on a business communication course using a social question-answering platform, this study explores the interplay among English proficiency, motivational orientations, and online engagement. Surveying 126 university students via a mixed-method approach, this research identifies distinct motivational orientations (intrinsic, extrinsic, and self-efficacy) existing during class activities, influenced by proficiency levels, with notable differences in online participation between beginner and advanced learners. The findings suggest that while online activities enhance peer interaction and teacher feedback, they may trigger anxiety in beginners, potentially diminishing motivation and self-efficacy. These results emphasize the need to tailor technology integration to proficiency levels and motivational orientations in ESP/EMI settings. Practical recommendations are offered for educators aiming to implement effective online activities and provide targeted support, particularly for beginner learners, thereby bolstering their motivation and selfefficacy.

In the post-COVID-19, the food industry is rapidly reshaping its market structure toward online distribution. Rapid delivery system driven by large distribution platforms has ushered in an era of online distribution of fresh seafood that was previously limited. This study surveyed 1,000 consumers nationwide to determine their online seafood purchasing behaviors. The research methodology used factor analysis of consumer lifestyle and Heckman’s ordered probit sample-selection model. The main results of the analysis are as follows. First, quality, freshness, selling price, product reviews from other buyers, and convenience are particularly important considerations when consumers purchase seafood from online shopping. Second, online retailers and the government must prepare measures to expand seafood consumption by considering household characteristics and consumer lifestyles. Third, it was analyzed that consumers trust the quality and safety of seafood distributed online platforms. It is not possible to provide purchase incentives to consumers who consider value consumption important, so improvement measures are needed. The results of this study are expected to provide implications on consumer preferences to online platforms, seafood companies, and producers, and can be used to establish future marketing strategies.

This study explores Korean EFL learner preferences and perceptions of digital composing (DC) with innovative online technology tools during the implementation of emergency remote learning measures. The research compares learner use of text-based DC and voice-based audio asynchronous online discussion (AOD). This paper investigates the following research problem: What digital modes of interactive, online instructional design can serve as appropriate, learner-accepted replacements for offline instruction? One prior finding indicated that Korean undergraduate EFL learners preferred text and audio DC to video modes. To follow up, this paper investigates 57 learners’ preferences and perceptions toward text-based and voice-based DC, and compares the results. The data analysis methods employ paired-samples Tests, and a thematic analysis to identify issues raised in student comments. The results reveal that learners’ levels of user satisfaction with voice-based audio AOD and their ratings of its perceived usefulness confirm that it can be a satisfactory, effective, and preferable task for engaging learners in digitally-mediated four-skills practice. Another finding is that utilizing a voice-based audio module did not significantly alter learners’ course satisfaction when superseding a text-based module. These findings inform pedagogical practice with empirical insights regarding learners’ use of digital technologies, levels of acceptance, and DC preferences.

The current study is designed to investigate the use of deductive and inductive grammar teaching approaches in online instructional videos in a fully online asynchronous learning context across four different grammar lessons. More specifically, the study aimed to analyze two aspects about these two options for grammar instruction; their impacts on effectiveness in learning the grammar, and also the students’ perceptions of the two options in terms of interest, effectiveness, and difficulty. To address these research aims, this study employed a quasi-experimental approach where 82 participants were divided into two groups, and each group was taught via only deductive instruction or only inductive instruction. As for the results, regarding effectiveness, an ANCOVA test resulted in no differences when comparing across all four lessons combined. Furthermore, Mann-Whitney U tests indicated no difference in effectiveness for each individual grammar lesson. Regarding student perceptions, ANOVA tests indicated no difference in the students’ perceptions of interest, effectiveness, or difficulty.
