Promotional videos have been increasingly adopted in social media marketing. Given that video production incurs high costs, evaluating the effectiveness of promotional videos is necessary. This research examines the effect of promotional video on visit intention through affective and cognitive destination images, respectively. Furthermore, grounded in the theoretical reasoning of social ties and persuasive intent, the effects of promotional videos disseminated by different sources (i.e., unknown users, friends, and marketers) are compared. Two experimental studies were carried out with 200 participants in Study 1 and 243 participants in Study 2. Study 1 revealed that the presence of promotional video induces visit intention through affective and cognitive destination images. Study 2 found that promotional videos disseminated by friends (versus unknown users) are more effective to induce visit intention because of positive cognitive destination image, while the video effects are indifferent between marketers and users. Meaningful implications are provided for destination marketers.

Communication as a process of interpreting signs has always existed in people's life. In post-information society, the communication between a person and a technological system through the specific sign-attaching process becomes widespread. Moreover, it somehow replaces usual communication between people. One of the means of communication in the digital space are video games. They not only play an important role in communication processes, but also are a special case of sign-creating and interpreting. The purpose of the article is to examine video games as a space of sign-based communication between a person and a game as a specific digital system. With the help of general scientific and hermeneutic methodology, the analysis of video games as a post-information society phenomenon which people communicate to has been conducted. The process of semiosis as attaching special meanings to signs has been traced in both manipulating in-game objects and characters and understanding rules of an in-game world.

최근 들어 사회적인 상호작용 방식이 동영상을 통해 정보를 주고받는 방식으로 변하고 있다. 그래서 본 연구에서는 '나'와 '다른 사람'의 영상을 구성요소로 하는 새로운 소셜 비디오 플랫폼을 제안하고자 한다. '다른 사람'의 개성(Personality)과 '나'의 개성이 '나'에게 어떤 영향을 주는지 알아보고, 2가지 요소를 어떻게 나타내주어야 하는지 알아보기 위해 사회적 영향 이론(Social Impact Theory)과 자기 점검 이론(Self-Monitoring Theory)을 적용하여 영상을 시청하는 '나'의 개성과 '다른 사람'의 개성이 사용자의 긍정성과 소속감에 어떤 영향을 미치는지 알아보았다. 그리고 이를 실증적으로 검증하기 위해 실제 소셜 비디오 플랫폼을 구축하여 실험을 진행하였다. 그 결과, 사용자들은 자신의 영상이 화면에 제시되었을 때, 긍정성을 더 많이 느끼는 것을 확인하였다. 하지만 자신의 영상이 함께 제시되면서, 주변영상에 나타난 다른 사람들의 모습이 여성성이 높아질수록 오히려 느끼는 긍정성은 줄어드는 것으로 확인되었다. 또한 다른 사람들의 모습이 남성성이 높을 때, 사용자는 소속감을 더 크게 느끼는 것을 확인하였다. 본 연구 결과를 통해 새로운 소셜 비디오 플랫폼의 구성과 형태에 대한 시사점을 제공할 수 있을 것으로 보인다.

A pattern classifier-based approach for recognizing internal states of human participants in interactions is presented along with its experimental results. The approach includes a step for collecting video recordings of human-human interactions or humanrobot interactions and subsequently analyzing the videos based on human coded annotations. The annotation includes social signals directly observed in the video recordings and the internal states of human participants indirectly inferred from those observed social signals. Then, a pattern classifier is trained using the annotation data, and tested. In our experiments on human-robot interaction, 7 video recordings were collected and annotated with 20 social signals and 7 internal states. Several experiments were performed to obtain an 84.83% recall rate for interaction engagement, 93% for concentration intention, and 81% for task comprehension level using a C4.5 based decision tree classifier.

신체 활동 증진을 위한 디지털 게임의 높은 활용에도 불구하고, 활동형 게임 이용에 영향을 미치는 요인에 대한 체계적 이해는 부족하다. 이 연구는 건강 행위의 생태학적 모형을 기반으로, 신체 활동에 영향을 미치는 요인을 개인적, 환경적, 사회적 요인으로 세분화하고, 신체 활동을 활동형 게임 이용과 일상적 신체 활동으로 구분하여 각 행위에 영향을 미치는 요인을 통합적으로 살펴보았다. 그 결과, 일상적 신체 활동은 세 요인이 모두 영향을 미치는 것과는 달리 활동형 게임 이용에는 사회적 요인만 영향을 미치는 것으로 나타났다. 이는 활동형 게임 이용 확대에 사회적 요인이 중요한 영향을 미칠 수 있음을 시사하고 있다.

Short videos are becoming more popular in mobile Internet age. Not only people's media consumption patterns have been changed by the rise of this new media form, but also it has posed challenges to public psychological well-being. For many netizens, their entertainment needs have been met by watching short videos. However, many side effects, such as addiction and anxiety, reduce users' subjective well-being instead of satisfying the entertainment motivation after watching short videos. Therefore, it has become a significant research problem in short videos to figure out how to get audiences to watch short videos on a regular basis while avoiding side effects like anxiety and addiction and improving audiences' subjective well-being. Based on the theory of Internet addiction, this study analyzed short video users using the 2×2×2 research method and explored the relationship between the length of use, addiction, anxiety, and subjective well-being of short video users. The results showed that short video users with different usage lengths showed significant differences in addiction, anxiety, subjective well-being, and online social support; innovative different short video users showed significant differences in addiction and anxiety, as well as a triadic relational interaction of short video users' anxiety under the interaction with self-efficacy and online social support. This study contributes to the advancement of internet addiction theory research and application, assisting short video users in avoiding addiction and anxiety, and improving the subjective well-being of short video users, thereby promoting the growth of the short video industry.

This study examines the relationship between social media advertisement and customer interest in the context of luxury brands. Further, this study investigates the effective ways to utilize visual types (pictorial advertisement and video advertisement) and contents types (website link and hash-tag) in social media advertising by proposing a time-series model to estimate the long-term effect of social media advertising on social search. We find that the pictorial advertisements are more effective than video advertisements, which provides a different result from previous existing research. In addition, advertisements using hashtags are more effective than web links due to efficiency of the search feature. Finally, since the number of brand fans also have a positive effect on advertising interest, it is essential to utilize social media advertising for the enhancement of customers' interests. Confirming that the effectiveness of social media advertising varies depending on how the visual contents and text are presented, this research can help marketing managers to assess predicted outcomes of using various methods of social media advertising.

This study was conducted with a non-equivalent control group experimental design to investigate the effects of a video-based infection control program through the application of the social cognitive theory on caregivers. Forty-six caregivers were recruited, with 23 pairs being randomly assigned to the control and experimental groups each. While the experimental group took part in the video-based education, the control group was involved in typical lectures. For two weeks, both groups were educated on the principles of infection control, medical and external handwashing, standard precautions, and quarantine. Their knowledge, performance, and self-efficacy were evaluated before and after the program. There was a significant increase in knowledge (p<.001 and p=.005) and infection control performance (p<.001) in the experimental and control groups. Similarly, self-efficacy, self-regulatory efficacy, task-difficulty preference and confidence significantly increased in the experimental group (p<.001). In the control group, only task-difficulty preference significantly increased (p=.005). Consequently, the online video-based infection control education program applying the social cognitive theory proved effective in improving the caregivers' knowledge and performance in infection control, and their self-efficacy. We suggest the use of this program in effective infection control education for caregivers in the future.

비즈니스 생태계의 불확실성이 증가함에 따라 공급사슬 내에서 야기는 되는 리스크의 종류도 매우 복잡하고 다양해 지고 있다. 특히 최근 정보통신기술의 발달로 기존 기업이 직면하던 전통적인 공급사슬 리스크 요인 이외에 새로운 리스크 요인을 고려할 필요가 있다. 대표적으로 소셜 미디어를 통한 부정적 구전을 예를 들 수 있다. 이에 본 연구는 대표적인 소셜 미디어인 유튜브(YouTube) 통해 제조 기업을 대상으로 부정적 구전의 파급력에 대해서 연구하였다. 보다 구체적으로는 부정적 구전의 제작자의 사회적 자본이 부정적 구전의 파급력에 어떤 영향을 주는 살펴보고, 그 과정에서 동영상의 부정적 감정이 어떤 역할을 하는지 연구하였다. 그 결과 부정적 구전 생성자의 사회적 자본은 부정적 구전의 규모와 속도에 영향을 주며, 나아가 동영상의 부정적 감정 단어는 동영상 제작자의 사회적 자본과 부정적 구전의 규모에 있어 조절효과를 보였다.
