In the COVID-19 era, people face situations that they have never experienced before, which alerted the importance of the ESG. Investors also consider ESG indexes as an essential factor for their investments, and some research yielded that the return on sustainable funds is more significant than on non-sustainable ones. Nevertheless, a deficiency in research exists about analyzing ESG through artificial intelligence algorithms due to adversity in collecting ESG-related datasets. Therefore, this p

This study deals with the impact of virtual reality (VR) features that are embedded in a hotel website on travelers' anxiety. Having more information is thought to be a factor in relieving anxiety in travel. A hotel website can be a good place for gathering information about the accommodation. In this study, we posit that a hotel website with VR functions should lead to a reduction in travelers' anxiety about travel. We built a website of a hotel and used VR functions to show the exterior, the l

Avatars are a unique cyber product that hold much potential to be a market success because they provide consumers with various psychological benefits such as anonymous personalization and an artificial sense of well-being in cyberspace. However, due to the very nature of avatars, consumer psychology, and the way that they are marketed to teenage consumers, avatars may also pose considerable threat to unsuspecting teenagers through addictive consumption and associated negative social consequences

This paper provides a perspective on cultural differences in e-mail use of virtual teams from the critical social theory (CST) point of view. CST can be used as a qualitative methodology in information systems research. Among CST concepts, Habermas' theory of communicative action is applied here for the purpose of drawing a plausible explanation for the phenomenon of cultural differences between East Asian countries and the West in the use of e-mail in virtual teams. East Asian countries such as

The Confucian tradition still dictates the behavior of many people in East Asian countries such as South Korea. Even in e-mail communication, people try their best to show signs of respect which is required by the Confucian tradition. This psychological barrier can be detrimental to the development of democracy as people are educated not to challenge opinions of elders or bosses. After a long military dictatorship, South Korea has emerged as a newly democratized nation where the Confucian tradit

This study introduces a sound-based mobile payment system as a wireless Web service. Using a mobile phone for payment for mobile commerce is essential for its success. The proposed system will use sound that is generated from the existing mobile phone and the sound can be recognized by the existing credit card reader of the shop with an installation of an ordinary microphone and simple software to process sound input. This system is a better system since it doesn't require customers to buy a new

Internet marketing has become an important issue for many businesses around the world which have any form of commercial presence on the net. It is often perceived that doing business on the Internet mostly requires competency in the technology area. However as many dot com companies are failing due to lack of revenue generation, which could be induced by the inadequate marketing and marketing research, practitioners and scholars of e-commerce are keen to obtain a better understanding of the whol

Clustering the rules in a knowledge-based system (KBS) on the basis of their static distance (lexical information) reduces the burden of understanding in the mind of the maintainer. This paper explores a clustering algorithm based on the Hopfield neural net algorithm that clusters automatically using lexical similarity. Using that algorithm, this paper presents a tool that can aid the maintainer in maintaining a KBS. The tool is the Rule Base Clusterizer (RBC) which structures the KBS rule base

This study presents an empirical evidence of benefit of narrative video clips in embedded virtual reality (VR) websites of hotels for relieving travel security concern. Even though it was proven that VR functions do provide some relief in travel security concern, a stronger VR website can be built when narrative video clips that show video clips with narration about important aspects of the hotel. Thus we created a video clip that showed and narrated about the escape route from the hotel room, a

This research was performed in order to empirically prove that telepsychiatry can result in overcoming of the Confucian cultural barrier which discouraged Korean patients from seeking psychiatric care. The Confucian culture of Korea forces its members to observe absolute conformity to the social norm. In this kind of culture it is very hard to admit one's mental illness and to seek medical help. Thus telepsychiatry might be a good alternative to face-to-face meeting-based psychiatry especially i
