As the un-tact and on-tact consumption culture has proliferated due to the impact of COVID-19, 'live commerce', a form of shopping while communicating with customers through real-time streaming broadcasting, is emerging in the commerce and distribution industry. Live commerce provides an environment where customers can get the convenience of online shopping and enjoy un-tact shopping more realistically while communicating with the broadcaster in real time, as if purchasing directly from an offline store. Therefore, purchases using live commerce are expected to increase further. In this study, based on the characteristics of live commerce, the main factors influencing the increase in purchase intention through live commerce were derived and their influences were verified. In particular, this study examined these factors in multiple dimensions with focusing on strong interactivity, realistic presence, and providing detailed reviews with high credibility for products as the features of live commerce. This research collected sample data from actual users of live commerce and empirically analyzed the significance of the factors influencing the purchase increase of live commerce, thereby providing implications for knowledge management in a newly changed commerce environment in the un-tact era.

'Live commerce', a brand new format of online shopping, is actively promoted in China recently. This research focused on 'Taobao-live', China's largest live commerce platform to investigate the relationships among para-social interaction, source characteristics (e.g., trustworthiness, attractiveness, and expertise), perceived ease of use, perceived usefulness, and shopping intention based on Technology Acceptance Model. A total of 536 Taobao live users were recruited through the Chinese research platform. The results showed that para-social interactivity positively affected perceived ease of use and usefulness, whereas the source characteristics had no significant effect on consumers' perceptions. Furthermore, higher perceived ease of use generated higher perceived usefulness, and both perceived ease of use and usefulness positively influenced consumers' intention to shop through Taobao live. This research can provide theoretical background for understanding the potential of live commerce platforms and help brands come up with effective online shopping strategies using live commerce platforms.

The concept of 'Picturing' is beyond the 'Illusion' of traditional art in the Digital Media era. It is a 'Suffering' of the 'Re-appearance' that is masquerade the 'Actual' as a 'Digital Apparition.' This study aims to concern the point of view on the above subject; the 'Picturing' through the analysis of communication problems in the digital era. To begin with, need to define the concept of 'Picturing' and how it is expected to have a role through the accessibility of medium use, intervention by body and images. Also, I suggest a new approach to 'Picturing' as a new mutual communication method. Body, Digital media, and Image. These three principles of 'Picturing' create huge benefits to our world/nature whether we want it or not. It seems to become more and more of powerful self-replicating organism. We have to be aware what sort of images are surrounding us and how transmitting it to where in/on our body via newest sophisticated media we use. 'Picturing' is an invasion of ordinary, no longer exists pleasure for body, no longer speaks intension of its next destination. It strongly self-grows and also controls us in the name of Digital media era. However, 'Picturing' is a mode of re-imaging activity and also suggestion of re-appearance practice.

Recently consumers to access various Word-Of-Mouth information on online. And eWOM (eWOM : electronic Word-Of-Mouth) information had an important effect on consumer attitude(purchase intention). The purpose of this study is to investigate what the general characteristics of eWOM and the effects of how these factors will affect credibility, eWOM acceptance and purchase intention. In this study, the model contains information characteristics variables(consensus, newness), community characteristics(tie strength, interaction) on eWOM characteristics. This study makes contributions as follows. First, information consensus had not effect on credibility. Second, information newness and community characteristics(tie strength, interaction) had a significant on credibility. Third, credibility is the important factor on eWOM acceptance. Lastly, eWOM acceptance had a considerable influence on purchase intentions.

지속적인 성장을 거듭하고 있는 온라인 게임은 사회적 상호작용과 집단 경쟁 등 스탠드 얼론(stand alone) 게임에서는 느낄 수 없는 새로운 재미를 제공하고 있다. 그럼에도 불구하고 온라인 게임 플레이의 경험 중가장 핵심적인 주제인 재미에 대한 연구는 휴리스틱한(heuristic) 연구에 머물고 있다. 본 연구는 기존 연구의 한계를 극복하고, 게임플레이의 재미에 대한 과학적인 평가를 위해 MMORPG의 재미 평가 모델을 제시하고, 그 유용성을 검증하는 데 목적이 있다. 본 연구는 동기이론, 몰입(Flow) 이론, 기존의 문헌연구와 설문조사를 통하여 온라인 게임의 핵심적인 재미 요소를 도출하였다. 도출된 20여개 의 요인들을 매트릭스 분석을 통해 범주화하고, Ermi & Mayra(2005)의 게임플레이 경험 모델에 통합하였다. 다양하고 정성적인 평가기준을 체계화하기 위해 AHP(Analytical Hierarchy Process) 이론에 입각하여 감각적 재미, 도전적 재미, 상상적 재미, 사회적 상호작용의 재미의 4개 측면을 포함하는 계층분석도를 구성하였고, 게임업계 전문가들의 검토와 중요도 평가를 통해 MMORPG의 재미 평가 모델을 제안하였다. 제안된 모델에 의해 구성된 설문문항을 3개 MMORPG를 즐기고 있는 이용자 87명을 대상으로 평가한 결과, WOW, Aion, Lineage2순으로 각각 75.247점, 68.649점, 62.205점을 얻어냈다. 이러한 평가 결과는 현재 MMORPG 중에서 가장 높은 시장점유율과 매출 실적이 좋은 WOW를 가장 재미있는 게임으로 선정하였고, Aion과 Lineage2도 현재의 시장 점유율과 매출 실적과도 정확하게 일치하고 있다. 이러한 결과로 본 연구에서 제안된 MMORPG의 재미 평가 모델의 유효성이 검증되었다. 본 연구의 결과는 가장 재미있는 게임의 선정뿐만 아니라 각 게임의 재미 요소별 강약점을 분석하여, 왜 어떤 게임은 성공적이며, 다른 게임들은 그렇지 않은가에 대한 이해를 제공할 수 있다. 결론적으로 본 연구에서 제안된 MMORPG의 재미 평가 모델은 어떤 게임이 가장 재미있는 게임인지를 선정하는데 활용될 수 있으며, 궁극적으로는 보다 구체적인 재미 요소별 분석을 가능하게 하여 보다 재미있는 온라인 게임을 개발하는데 기여할 것이다. 그러나 다른 장르까지 확장하여 활용하기 위해서는 후속 연구가 뒷받침되어야 한다.

Online reviews play an essential role in the consumer's purchasing decision-making process, and thus, providing helpful and reliable reviews is essential to consumers. Previous online review helpfulness prediction studies mainly predicted review helpfulness based on the consistency of text and rating information of online reviews. However, there is a limitation in that representation capacity or review text and rating interaction. We propose a CNN-RHP model that effectively learns the interaction between review text and rating information to improve the limitations of previous studies. Multi-channel CNNs were applied to extract the semantic representation of the review text. We also converted rating into independent high-dimensional embedding vectors representing the same dimension as the text vector. The consistency between the review text and the rating information is learned based on element-wise operations between the review text and the star rating vector. To evaluate the performance of the proposed CNN-RHP model in this study, we used online reviews collected from Amazom.com. Experimental results show that the CNN-RHP model indicates excellent performance compared to several benchmark models. The results of this study can provide practical implications when providing services related to review helpfulness on online e-commerce platforms.

Online game business has emerged as the most lucrative entertainment industry, with over 10 million players in South Korea. The popularity of online games can be attributed to the availability of broadband network and the presence of numerous PC Bangs and around the country, which have pushed online games into the mainstream entertainment culture. The age distribution of online game players is expanding and a variety of new games are under development to target certain age groups. While the interactive entertainment market continues to expand, with many new online game publishers entering the market, relatively little is known about which factors influence online game players' behavioral intentions to play continuously n this area. It appears that in this extremely attractive and growing services segment, academics, as well as practitioners, would benefit from investigating the relationships among the players' intentions to play, flow, and the impacts of several other key game-related constructs n consumer behavioral intentions. Several types of interaction in on-line games and their relationship with the flow construct are investigated, and the resulting conceptual model is proposed. Based on data collected from online questionnaire survey, the validity of the simultaneous equation model has been tested and interesting conclusions have been developed concerning the relationships between the players' behavioral intentions to play, flow, and interactions. Other interesting results concerning game development strategy are also provided.
