This paper employs a comparison between two forms of online instruction to investigate which form is more preferred, as well as the advantages and the disadvantages for both forms of online education. The data for the research were collected via an online questionnaire that was purposely created for the research. A sample of 26 undergraduate students of Yonsei University, South Korea, were employed for this study. Pre-tests and post-tests were performed to compare between pre-recorded video lectures and live ZOOM lectures. The results show that students prefer pre-recorded video lectures to live ZOOM lectures; 53.8% chose pre-recorded video lectures, 7.7% chose live ZOOM lectures, and 30.8% chose both pre-recorded and ZOOM lectures when they were asked to select their preferred method of learning. Furthermore, we asked several questions, and the mean values were compared. The results of this research showed that pre-recorded video lectures are preferred to live ZOOM lectures due to their flexibility, convenience, and educational effectiveness. However, learning through video lectures depends on students’ motivation to get through those materials on their own. Lack of motivation and clear deadlines to watch those video lecture materials could end up in an accumulation of workload, which would be difficult to overcome before examinations.

The amount of food wasted by Korean households is significant and to some extent could be preventable. It is not well illustrated how Korean students perceive food waste and how much they know about the consequences of food waste. This study aimed to examine Korean students’ perception of food waste. Overall, results show that students’ perception of food waste varies in different clusters. Considerate food wasters (cluster 1) are knowledgeable and have much information regarding food waste. This paper suggests that additional information about how to preserve food and about issues related to food wastes, which cause a bigger environmental problem over the long term, could influence the behavior of this cluster, reducing perhaps further food waste. On the other hand, unwitting and ruthless food wasters, who are in clusters 2 and 3, need extra attention. Marketers should initiate educational campaigns to raise awareness of food waste for students and youth. Students who fall under these two clusters may need to pay extra attention to their shopping behavior. They should be more connected to their food, and to their purchase behavior, which may reduce food waste.

The purpose of this study was to explore the link between smartphone use and sleeping disorders and depression among university students in South Korea. South Korea has the highest mobile phone penetration rate as well as the highest rate of suicide of any of the Organization for Economic Cooperation and Development (OECD) nations, thus making this study of great importance. The core aim was to see whether the excessive use of smartphones has an association with sleeping disorders and depression. A cross-sectional analysis was performed to establish if there was any link between smartphone use and sleeping disorders and depression. Samples from 188 participants were used for this study. Data were collected using two well-established questionnaires, the Center for Epidemiologic Studies-Depression (CES-D) and the Athene Insomnia Scale (AIS), as well as a few questions on smartphone use. A few demographic questions were added to the questionnaire. The results of this study concluded that a significant relationship exists between smartphone use and depression. However, the finding of this research could not uncover a significant relationship between smartphone use and sleeping disorders among university students in South Korea. The excessive use of smartphones shows a relationship to an unhealthy lifestyle. There is a clear indication that the overuse of smartphones could be linked to depression. Furthermore, the study found that students with depression also tend to have sleeping disorders.

The purpose of this study was to look into the factors affecting South Korean college students’ luxury goods purchases and their intent to buy them.
