  • Proof of Work (PoW) based blockchains have limitations in throughput, time consumption, and energy efficiency. In these systems, a miner will consume significant time and resources to obtain a reward for contributing to the blockchain. To overcome these limitations, recent research on blockchains are focused on accelerating the speed, scalability, and enhancing the security level. By enhancing specific procedures of blockchain system, the level of data integrity supported by the blockchain can become more robust, and efficient. In this paper, a new blockchain consensus model based on the Bryllite Consensus Protocol (BCP) is proposed to support a hyper-connected massively multiplayer online game (MMOG) ecosystem. The BCP scheme enables users to participate directly in new consensus processes through a Proof of Participation (PoP) algorithm. In this model, the consensus algorithm has a simpler form while maintaining high security level. In addition, because the BCP scheme gives users an equal chance to make a contribution to the blockchain, rewards are distributed in an equal fashion, which motivates user participation. The analysis of the proposed scheme is applied to the Bryllite consortium blockchain system (homed in Hong Kong), which is a new blockchain network developed for international game industries, gamers, and game events.

  • This study identifies the socio-psychological factors on athleisure wear purchase behavior and focuses on the effects of participation motives in sports leisure activity. This research compares athleisure wear purchase behavior among the three groups segmented by participation motives for sports and leisure activity. An online survey on male and female consumers between the ages of 20 and 50 provided 319 responses that were analyzed using SPSS 20.0. The factor analysis and reliability analysis, cluster analysis, variance analysis, Duncan test, and Chi square test were conducted. The results were: 1) From a result of the factor analysis on consumers' sports leisure participation motives clearly showed factorial structures including social interaction, physical health, and pleasant feeling. 2) Cluster analysis indicated three groups of participation motives in sports and leisure activity such as passive motivating type, social interaction type, and wellness type. 3) Consumer groups showed significant differences in purchase reasons, preferred brands, product items, and pursued performance attributes for purchasing athleisure wear products.

  • 본 연구는 부산 시내에 소재하고 있는 대학 방사선(학)과에 재학중인 학생들을 대상으로 온라인 수업에 대한 만족도를 알아보기 위해 설문조사를 실시하고 분석하였다. 그 결과 온라인 수업에 대한 만족도는 학제에서는 4년제 대학 재학생의 만족도가 점수가 높게 나타났고 학습 참여 만족도를 제외하고 통계적으로 유의미한 차이가 나타났다(p<0.001, p<0.05). 학년별 수업 만족도는 4학년의 점수가 높게 나타났고, 학습 참여 만족도를 제외하고 통계적으로 유의미한 차이가 나타났다(p<0.001, p<0.01, p<0.05). 강의 과목수에 따른 만족도 조사에서는 4~7개의 강의를 수강한 학생들의 점수가 학습 참여 만족도를 제외하고 높게 나타났으며 통계적으로 유의미한 차이를 나타냈다(p<0.01, p<0.05). 교수자와의 소통 방법에서는 이메일을 사용한 학생들의 점수가 높게 나타났으며 강의 만족도에서는 통계적으로 유의미한 차이를 나타냈다(p<0.05). 온라인 수업에 대한 하위변수들 간 상관관계 분석에서는 전 영역에서 통계적으로 유의미한 상관관계가 성립되었다. 학생들이 선호하는 수업방식은 녹화수업과 유튜브 등 외부콘텐츠를 이용한 수업이 많았고, 온라인 수업의 장점을 묻는 질문에는 반복적 수업과 시간과 장소에 구애받지 않는 것이 장점이라 답변한 학생이 많았다. 온라인 수업의 단점을 묻는 질문에는 집중력저하와 교수자와의 소통 부족이라고 답변한 학생이 많았다. 본 연구는 앞으로 늘어날 온라인 수업의 만족도를 향상시키기 위한 기초 자료를 제공하고자 시행하였다. 따라서 본 연구의 결과를 바탕으로 온라인 수업에 대한 학생들의 만족도가 향상될 수 있도록 양질의 온라인 수업이 더 많이 제작되기를 기대한다.

  • Even through many professional organizations increasingly use Q&A sites in their online communities for information sharing, there are few studies which examine what is really going on in the Q&A activities in professional online communities (POC). This study aims to examine the interaction patterns and contents posted in the Q&A site of a POC, KOSEN, a science and technology online community in South Korea, focusing on how actively scientific information and knowledge are shared. The interaction patterns among the participants were identified through social network analysis (SNA) and the contents in the Q&As were examined by content analysis. The results show that the overall network indicated a moderate level of participation and connection and answerers especially tended to be active. Also, there are different interaction patterns depending on academic fields. Relatively few participants were posting leaders who seemed to steer the overall interactions. Furthermore, some content related to manipulation and explanation for experiments, which are in urgent need, seem to be posted in the sites more frequently with more amounts. Combining both SNA and content analysis, this study demonstrated how actively information and knowledge is shared and what types of contents are exchanged. The findings have practical implications for POC managers and practitioners.

  • Online Word-of-Mouth communication, or eWOM, has dramatically changed the way people network, interact, and share knowledge. Studies have examined why consumers choose to share knowledge online, especially online product reviews, as well as the motivations of individuals to share product ideas online. However, the role of gender in shaping the motivation and types of knowledge shared online has been given little consideration. Using concepts from Social Exchange Theory and the Theory of Reasoned Action, we address this research gap by developing and testing a model of gender's influence on knowledge sharing in a social media context. A PLS analysis of survey data from 257 students indicates that reputation, altruism, and subjective norms are key motivators for knowledge sharing intention in social media. More importantly, that gender plays a moderating role within the motivation-knowledge sharing relationship. We also find that subjective norms have a greater impact on knowledge sharing with women than with men. Collectively, our research results highlight individualized factors for improving customer participation in external facing social media for marketing and product innovation.

  • As customers' participation in B2C e-commerce increases, customers are getting more involved in the delivery of services, which may even go beyond the completion of service transactions. To examine such proactive extra-role online customer behavior, we delve into organizational citizenship behavior framework, which has been recently extended to examine customer citizenship behavior (CCB) in the service market area. Although CCB is vital for online retailing success, MIS and e-commerce research efforts have generally focused on the customer's customer coproduction that are customer in-role behaviors. Moreover, although the effect of information created by anonymous strangers on other customers increase, interpersonal trust research have focused on only the relationship between a seller and a customer. Therefore, this study attempts to answer two research questions: What are motivational factors that affect CCB? How differently do the two kinds of interpersonal trusts (trust in online retailer and trust in customers) influence customers?

  • In order to respond to changes in the industrial environment such as the 4th industrial revolution, university education also needs active educational innovation efforts. This study proposed a construction construction hybrid curriculum that can actively utilize online education in the direction of educational innovation in domestic universities. The hybrid curriculum was based on online learning through lecture videos used in team-based learning. The hybrid curriculum additionally allows learners to choose their learning methods. In a hybrid class, learners can choose the class participation method they want from offline classroom or online real-time. Hybrid classes are considered to strengthen learners' options and take a step forward in learner-centered education.
