During the last decade, social live streaming service like Periscope, Ustream, and YouNow has developed from a niche market into a mainstream activity. In this media environment, social live streaming service has a tremendous impact on the social behaviors of users. Despite the rapid development, there are a lack of studies to make better understand the media environment changes through social live streaming service. This study adopted an affordances approach that leads us to identify six distinctive social affordances (visibility, accessibility, information sharing, social interaction, role-taking, interactive revenue) for user engagement in social live streaming service. Specifically, this study explores the impact of social affordances on perceived flow, followed by user engagement including passive and active engagement. Empirical data analysis with 258 questionnaires suggests that social affordances affected users' flow perception, and flow has an effect on active as well as passive engagement. Contrary to the expectation in a hypothesized research model, only the impact of accessibility on flow was rejected.

In the last few years, a new type of synchronous social networking services (SNSs) has emerged—social live streaming services (SLSSs). Studying SLSSs is a new and exciting research field in information science. What information behaviors do users of live streaming platforms exhibit? In our empirical study we analyzed information production behavior (i.e., broadcasting) as well as information reception behavior (watching streams and commenting on them). We conducted two quantitative investigations, namely an online survey with YouNow users (N = 123) and observations of live streams on YouNow (N = 434). YouNow is a service with video streams mostly made by adolescents for adolescents. YouNow users like to watch streams, to chat while watching, and to reward performers by using emoticons. While broadcasting, there is no anonymity (as in nearly all other WWW services). Synchronous SNSs remind us of the film The Truman Show, as anyone has the chance to consciously broadcast his or her own life real-time.

Consumers' shopping experience has recently expanded to mobile and social networks; in addition, online fashion retailers started to focus on real-time interaction services as an emerging marketing tool. This study explores the consumer' shopping experience based on social live streaming services (SLSS) to investigate consumer's response behavior and effects through perceived service quality. An online survey method was conducted and a total of 186 female consumer panels were collected. The results indicate that cognitive communion of co-experience had a significant effect on perceived SLSS service quality (responsiveness, contents informativeness, playfulness, system availability). Service quality of SLSS (responsiveness, contents informativeness, and playfulness) had significant effect on trust in SLSS seller while system availability had no significant effect. Also, trust in seller showed significant effect on purchase intention. Last, it was confirmed that the moderating effect of purchasing experience of SLSS was significant in the relationship between cognitive communion and responsiveness/playfulness. There was also an additional significant moderating effect of purchasing experience between system availability and trust in seller.

Live-streaming commerce is attracting attention as a noticeable trend in the retail industry. It is a new mobile shopping service platform developed by combining live streaming with e-commerce technologies. This study examined the impact of para-social interactions on consumer impulse buying behavior and investigated the impact through task complexity as well as perceived amount of information. To achieve this goal, 203 women using a mobile commerce participated in an online survey after experiencing beauty live-streaming commerce. The collected data were analyzed using SPSS 25.0, AMOS 23.0, and SPSS PROCESS Macro program. The results of the study revealed that para-social interactions negatively influenced task complexity, positively influenced perceived amounts of information, and positively influenced impulse buying behavior. In addition, impulse buying behavior was negatively influenced by task complexity versus positively that was influenced by perceived amounts of information. The impact of para-social interactions on impulse buying behavior is mediated by task complexity and perceived information. The findings of this study contribute to the theoretical extension of para-social interaction on impulse buying behavior in the context of live-streaming commerce. The implications of the findings suggest practical marketing strategies for digital media commerce retailers.

최근 ICT 산업게는 가상현실에 주목하고 있다. 시공간의 제약을 극복하고 실제 체험하는것과 비슷한 효과를 제공하는 VR 콘텐츠는 향후 유통 분야에도 폭넓은 활용이 예상된다. 대부분의 O2O 서비스에서 사용하고 있는 VR 기술은 단순히 360도 파노라마 형식의 사진을 보여주거나 VR 카메라로 중계 방송을 하는 콘텐츠가 대부분이었다. 따라서 본 논문에서는 3차원 VR 영상 스트리밍 서비스를 이용한 콘텐츠를 O2O 부동산 중개 서비스에 접목하여 360VR 컨텐츠 확장 가능성을 제시하고자 한다.

Recently, SDN and NFV technology have been developed actively and provide enormous flexibility of network provisioning. The future network services would generally involve many different types of services such as hologram games, social network live streaming videos and cloud-computing services, which have dynamic service requirements. To provision networks for future services dynamically and efficiently, SDN/NFV orchestrators must clearly understand the service requirements. Currently, network provisioning relies heavily on QoS parameters such as bandwidth, delay, jitter and throughput, and those parameters are necessary to describe the network requirements of a service. However it is often difficult for users to understand and use them proficiently. Therefore, in order to maintain interoperability and homogeneity, it is required to have a service abstraction layer between users and orchestrators. The service abstraction layer analyzes ambiguous user's requirements for the desired services, and this layer generates corresponding refined services requirements. In this paper, we present our initial effort to design a Smart Service Abstraction Layer (SmSAL) for future network architecture, which takes advantage of machine learning method to analyze ambiguous and abstracted user-friendly input parameters and generate corresponding network parameters of the desired service for better network provisioning. As an initial proof-of-concept implementation for providing viability of the proposed idea, we implemented SmSAL with a decision tree model created by learning process with previous service requests in order to generate network parameters related to various audio and video services, and showed that the parameters are generated successfully.

모바일 기술과 비디오 스트리밍 기술이 발달하고 미디어 플랫폼이 다변화 되면서 '페이스북 라이브', '아프리카 TV'와 같은 모바일 개인방송은 기존 IT 시스템과는 다른 수용 패턴을 보이고 있다. 모바일 개인방송 시청 요인에는 오락적 동기가 가장 큰 비중을 차지하므로 기존의 외재적, 생산적 동기 중심의 시스템 수용 이론으로는 연구의 한계가 있다고 판단하였다. 이에 본 연구는 오락적 동기 시스템 수용 분석에 특화된 HMSAM(Hedonic-Motivation System Adoption Model)을 이론적 틀로 활용하여 모바일 개인방송 시청자의 수용 요인에 어떠한 오락적 동기가 작용하는지 실증적으로 알아보고자 하였다. 연구 변인에는 즐거움(Joy), 시간 흐름 미인지(Temporal Dissociation), 현실도피감(Escapism), 몰입(Focused Immersion)과 같은 내재적 동기가 포함되었다. 또한 인지된 사용 용이성(Perceived Ease of Use), 인지된 유용성(Perceived Usefulness), 시청 의도(Intention to Watch) 변인도 포함되었다. 연구 분석은 Multi-indicator 모형의 구조방정식을 통하여 변수들 간의 인과관계와 유의성을 검증하였다. 연구 결과, 모바일 개인방송 시청의 즐거움은 시간 흐름 미인지, 현실도피감, 인지된 사용 용이성과 긍정적(+)인 관계를 맺고, 시청의도와 몰입에도 긍정적(+)인 영향을 주었다. 현실도피감 역시 몰입에 긍정적(+)인 영향을 주었다. 본 연구는 오락적 동기 시스템 수용에 대한 최신 연구인 HMSAM 모델을 이론적 틀로 활용하여 모바일 개인방송 시청 요인들을 새롭게 분석하였다는 점에 의의가 있다. 향후 재미와 오락의 개념을 더 세분화하고, 미디어의 능동적 수용과 수동적 수용을 추가적으로 살펴본다면 더욱 발전된 후속 연구가 진행될 수 있을 것이다.
