In this paper, we propose a strategy of charging by analyzing the difference of path coefficient according to whether consumers are free or not, rather than presenting strategies for charging. Mobile devices have become so popular that they are called necessities. Companies have to adapt to the mobile environment and respond to the situation, and have to expand market opportunities strategically. In this study, we extend the technology acceptance model to analyze the incentives of consumers' behavior by analyzing the difference in the effect consumers perceive as a moderating variable, whether paid or free. Efforts to maximize company's inherent profit continue, and in particular, charging is a strategy that all companies should pursue in the mobile environments. It is necessary to grasp the degree of the consumer's response to free and charge. The model of satisfaction with the continuous use and the word-of-mouth intention, which is the behavior intention, is presented by adding parameters of satisfaction to the technology acceptance model. In addition, we try to derive implications by analyzing the influence of moderating effects of whether free or not.

This study analyzed the impact of YouTube creator characteristics and channel access factors on the intention to continue watching content, noting that the development of the digital media environment has diversified media audiences' content preferences and access routes. Specifically, we analyzed the effects of YouTube creator trustworthiness, attractiveness, familiarity, and social influence, as well as the effects of recommendation services on perceived usefulness, perceived ease, and perceived enjoyment. The study found that creator credibility and recommendation service had a positive impact on the perceived usefulness of content, while intimacy and charm were important factors in increasing the easy of use and playfulness of content. These perceived usefulness, ease, and playfulness also had a strong positive impact on users' intention to continue watching the channel. This suggests that trust and intimate relationships with creators and appropriate content recommendations play an important role in increasing user satisfaction and channel persistence. The significance of this study's analysis of creator and channel access factors based on the extended technology acceptance model is that it shows the potential for extending and applying the existing technology acceptance model to the digital content environment.

Recently, as demand for delivery services has increased rapidly due to COVID-19, the food service O2O(Online to Offline) platform has also grown significantly. This study aimed to verify the influencing factors on continuance use intention of O2O platform using the Information Service Success Model and Post Acceptance Model. An online survey was conducted on 379 consumers who used the food service O2O platform in the past six months, and the collected survey was analyzed using SPSS 26.0 and AMOS 24.0. As a result of the verification, in the influence relationship between the Information Service Success Model and Post Acceptance Model, system quality was found to have an effect on perceived usefulness, but information quality and service quality were rejected for perceived usefulness and were partially adopted, The rest were all found to have a significant effect. In the moderating effect according to the amount used, the intention to continue using was stronger when the group who spent more than 30,000 won was satisfied. These results support previous research on O2O platforms and provide academic implications as well as practical implications for practitioners in the food service industry.

This paper focuses on the formation of contract under CISG through the case by the Korean court. Under the CISG, an offer means that a proposal for concluding a contact constitutes the offer, if it is sufficiently definite and indicates the intention of the offeror to be bound in case of acceptance. An acceptance is statement made by or other conduct of the offeree indicating assent to an offer, and this statement purports to be an acceptance but contains additional or different terms which do not materially alter the terms of the offer constitutes an acceptance. In practice, parties negotiate for lots of contract terms to conclude the contract, and the last reply indicating of assent which is made by statement or other conduct to a proposal for concluding a contract would be an acceptance. At this time the most important factor is the intention of parties whether they intend the offer or the acceptance, Purchase order by buyer or Offer Sheet by seller would be understand as condition precedent for the formation of contract. Nevertheless, keep in mind that the Korean court is consistent in the way Purchase order by buyer or Offer Sheet by seller is an acceptance to conclude contract.

When digital media and images are combined, their significant sociocultural impacts can be exercised. Therefore, this study analyzes digital images shown in such trends of digital media compared to the digital fashion from an aesthetic perspective. Research and empirical studies are focused upon to analyze the aesthetic characteristics of digital fashion. Digital Fashion comprehensively refers to fashion design using computers and software, and is considered as "Fashion Design utilizing Digital Technologies" including computer software and hardware perspectives, so that it may be renamed "Digital Fashion." The esthetic characteristics shown in the Digital Fashion defined above are analyzed according to how media philosophers conceptualize the digital image. First, from the perspective of creation, Digital Fashion Images are technical images produced by computers. Uncanny characteristics expressed through virtual images look more realistic than the actual ones used in experimental works of fashion designers. Such virtuality dynamically expresses various colors and fabric patterns through lights using digital technologies that do not yet exist in cloth form, rather in a non-material form of dynamic virtual imagery. Digital fashion images on monitors express digital fashion designs by shaping virtual images through 3D printing. Second, Digital Fashion Images from the perspective of acceptance are created through deconstruction, while fashion has only been previous viewed visually, Digital Fashion delivers immersions of visual touches as if directly experienced for accepters. Digital Fashion will continuously develop and become more influential as it converges with digital media.
