웹 기반 크라우드펀딩 플랫폼은 소자본 기업들에게 재정적 위험을 줄이고 새로운 제품을 선주문을 통해 안정적으로 생산할 수 있는 기회를 제공한다. 한편 크라우드펀딩 프로젝트는 기업들에게 신상품을 대량생산 이전에 테스트할 수 있는 채널로서 또한 도움을 주고 있다. 이러한 장점들에도 불구하고, 기업과 소비자의 관점에서 보았을 때 웹기반 크라우드펀딩 플랫폼은 리테일 환경에서 많은 제약이 있는 것이 사실이다. 가령 웹 기반 플랫폼의 제한된 사회적 요소들은 그 본질상 다수의 사회적 지지를 필요로 하는 크라우드펀딩 프로젝트의 기본적 특성과 상치되며 이는 크라우드펀딩에 참여하는 소비자들의 태도에 영향을 줄 수 있고, 따라서 웹기반 크라우드펀딩 플랫폼에서 소비자가 경험하는 사회적 요소의 메커니즘에 대한 이해는 중요하다. 이에 본 연구에서는 크라우드펀딩 플랫폼의 사회적 요인이 소비자의 참여와 평가에 미치는 영향을 실증적으로 알아보고자 했다. 사회적 영향이론과 사회적 실재감 이론을 바탕으로, 후원자 사회 집단 크기, 사회적 실재감을 독립변수로 설정하고 구매자의 참여의도를 종속변수로 연구모형을 설정한 후 온라인 설문을 통해 얻어진 데이터를 통계분석하여 결과를 도출했다. 크라우드펀딩 구매자들에게 제공되는 후원자 사회 집단 크기와 사회적 실재감이 구매자의 참여의도에 영향을 미치는지 살펴본 결과, 후원자 사회 집단 크기와 사회적 실재감은 구매자의 참여의도에 유의미한 정의 영향을 미치는 것으로 나타났다. 각각의 요인들의 표준화 베타 계수를 보면, 후원자 사회 집단 크기보다 사회적 실재감이 구매자의 참여의도에 더 큰 영향력을 미친다는 것을 알 수 있었다.

로커티브 미디어는 단순히 기존 미디어에 물리적인 좌표값이 더해진 것이 아니라 사용자 개개인의 공간, 장소, 위치를 미디어의 속성으로 포섭하였다는 점에서 본질적인 특성을 지닌다. 이 연구는 연구자가 현재 로커티브 미디어 콘텐츠들이 '위치 정보에 기반'하고 '증강현실'과 밀접한 관련을 맺은 채 제작되는 경향에 주의를 기울이면서 시작되었다. 연구자는 기술의 발전으로 미디어 환경이 변화할 때 매체 이용자들의 심리적인 경험 관여가 어떻게 발현되는지, 구체적으로는 현재의 로커티브 미디어 환경에서 로커티브 미디어를 통해 형성되는 사용자들의 '사회적 현존감 인식'이 어떠할지 의문을 느꼈다. 특히 로커티브 미디어를 통해 형성되는 사용자들의 사회적 현존감 인식이 기존 컴퓨터 매개 커뮤니케이션(CMC)의 특징과 상충되는 요소들을 지니고 있다는 점은 이러한 의문을 증폭시키는 역할을 하였다. 연구자는 이 연구를 통해 현재 로커티브 미디어 환경에서 적절한 현존감 모형을 제안하고, 매개화된 상호작용의 채널로서 로커티브 미디어에서 형성되는 사회적 현존감의 특성을 알아보며, 여기에 로커티브 미디어의 '위치 정보 기반' 속성과 '증강현실'이 기여하는 바를 정성적인 방법론으로 살펴보았다.

Purpose - This study aims to identify the effects of communication cues, anonymity, and social presence on group polarization in computer-mediated communication (CMC) settings. Extant literature has introduced some theoretical backgrounds of social presence and SIDE (Social Identity model of Deindividuation Effects) to explain the effects of communication cues and anonymity. The concept of social presence emphasized the mediating role on communication cues and anonymity. However, most literature did not measure social presence and compare group polarization of all condition groups. This does not sufficiently explain the result of group polarization. Research design, data, and methodology - We believe that the direct impact of anonymity on group polarization can provide a more admissible and clearer explanation for the results. In addition, this study categorizes anonymity into two levels, as anonymity of group and anonymity of self. To justify the anonymity view, a laboratory experiment was conducted. The experiment was conducted in communication cues settings (visual cue; without visual cue) and anonymity settings (identified; anonymous). Each of the four settings has 10 groups consisting of five subjects each (total 200 subjects). The subjects are undergraduates from a large university, majoring in business. All experimental procedures and calculations of choice shift and preference change follow the literature. Results - First, the removal of visual cues does not produce a significant impact on group polarization, which cannot be explained by the social presence view. Second, the anonymous condition does not significantly affect group polarization, which also cannot be explained by the social presence view. However, the anonymous condition directly affects group polarization. Specifically, anonymity of self has a stronger effect on group polarization than anonymity of group. The result explains about the leading factor affecting group polarization. This study examines another view of how computer-mediated communication may be associated with group polarization. The process and outcome data from the experiment reveal that group polarization is not affected by level of social presence, but by level of anonymity. Group discussions conducted with visual cue CMC setting and identified CMC setting result in weaker group polarization. Conversely, group discussions conducted without visual cue CMC setting and anonymous CMC setting lead to stronger group polarization. The results of the study have the following implications. First, they provide clues for business organizations to design the most appropriate media conditions and preemptive social conditions to implement when making group decisions through CMC, to maximize achievements, generate amicable agreements, or actively share information. Second, this study can be useful in analyzing different adverse effects generated through Internet use. Conclusions - This research can help explain discussions and decision-making actions on Internet forums, which have recently increased, as well as providing a foundational basis in newly establishing policies for the forums. Finally, it should be noted that many other factors such as group size, topics, and group history may affect group polarization. These should be examined in future studies.

Social media have been rapidly and widely adopted in various areas, and tourism industry can be one of potential growing areas. Tourist and travelers would like to share their photos and stories as well as find others' experiences. People are doing their activities through social media. Regarding relaxing entertainments, information sharing, escapism, social interaction, tourism activities are being paid attention by majority of users in social media. However, Although people have various motivation for using social media, academically researchers have not actively studied on the phenomenon arising from tourism industry. Therefore, this study aims to the reasons for tourism information searching motivational factors of social media that influence perceived value and its consequences such like before-searching, during-searching, and after-searching and divided social media into two types according to the level of social presence, and then empirically verified them. Antecedent variables divided into benefits including perceived usefulness and information quality and sacrifices including complexity and perceived effort. Our analysis results show that both of dimensions had the greatest effect on perceived value of social media use, which affect the consequences.

The objective of this paper is to contemplate a possible alternative to the examination, published as a research article in Information Systems Research(Sia et al. 2002), of the effects of communication cues, anonymity, and social presence on group polarization in computer-mediated communication(CMC) settings. Sia et al. introduced the concept of social presence to explain the effects of communication cues and anonymity on group polarization, but we believe that anonymity alone provides a clearer explanation of the results. This paper classifies levels of anonymity to provide possible explanations for Sia et a1. (2002)'s results and presents the results of a new experiment to confirm our explanation. We also want to emphasize that our comments are not intended to disparage the usefulness of social presence as a mediating variable to explain group polarization; our intention instead IS to encourage further investigation to better understand group polarization in CMC settings.

Despite current regulations requiring social distancing due to coronavirus disease 2019, problem-based learning (PBL) requires student interaction to achieve common goals and enhance critical thinking and deep learning abilities. Social presence in the online education environment reduces both perceptions of physical distance and psychological distance in interactions. This study aimed to compare PBL activities between in-person and videoconferencing classes, and to investigate social presence and learning satisfaction in a videoconferencing PBL environment. The PBL consisted of six modules for both the first and second years of Chonnam National University Medical School. As social distancing was strengthened, the second class of the fifth module in both years was converted to an online format and the fifth module was excluded. The first four PBL modules were conducted as in-person classes, but the last PBL module was administered via videoconferencing. After the final PBL module, 100 (81.3%) first-year medical students and 90 (79.6%) second-year students were asked to complete a self-administered questionnaire on social presence and learning satisfaction. There were no significant differences in the small group activities of tutorial sessions between in-person and videoconferencing classes. In the online videoconferencing class, students who had favorable attitudes toward the tutors' social role and interactions with peers showed high satisfaction with their learning. In conclusion, online videoconferencing allows students to simultaneously perceive their interactions with others and social presence, even at a distance. Tutors can enhance a sense of online community and collaborative learning as facilitators of online PBL.

This study intended to evaluate the viability of cyber education in terms of learning satisfaction and learning achievement. The study integrated two research streams such as social presence model and learning environment model. Where the learning environment model emphasizes the components of learning aids, social presence model considers more deeply the relationships among peers and with instructors. These two research streams have been considered relatively independently. The study integrated these ideas and measured their reliabilities and validities. The results demonstrate that the two constructs are relevantly independent and both of these constructs are very important considerations for the success of cyber education. The study concludes that cyber education 2.0 requires more social presence factors than the learning environment factors such as technological development or new equipments.

Purpose - The objective of this study is to identify the effects of the communication cues and anonymity on group polarization in mobile communication settings, both in terms of route and extent. Research design, data and methodology - Laboratory experiments were conducted to achieve the above research objective; the effect of communication cues on group polarization with social presence as mediation and the direct effect of anonymity, social presence, and perceived cohesion were analyzed. The experiments were conducted by the participation of 240 people, who were divided into 48 groups of 5 people. Results - According to the results, the difference in intergroup polarization due to communication cues and anonymity was insignificant. From this analysis, the structural equation model, communication cues and anonymity did not affect group polarization through social presence. Moreover, anonymity did not affect group polarization through perceived cohesion; however, anonymity directly affected group polarization. Conclusions - This research can help to explain the discussions and the related decision-making actions on internet forums, which have recently come to the rise as well as provide foundational basis in newly establishing policies for the forums.
