The purpose of this study is to gain knowledge about the influence of running time of 3D stereoscopic video on audience perceptions. This study compares the influence of running time between 20 minutes and 40 minutes of 3D stereoscopic music shows on audience perceptions such as perceived characteristics, impression, presence, entertainment, fatigue and unnatural looking images. After experiment with 40 samples, the present research found that when people watched shorter 3D stereoscopic music video, they perceived more 3D functionality, such as depth, image conveyance and message conveyance. The results also suggest that people who watched shorter 3D stereoscopic video felt more impression such as definiteness and freshness from the 3D images. Moreover, the result confirm that when watching shorter 3D images, people felt more a sense of presence. Findings of this study have important practical implications how running time is important to 3DTV viewers. Since the nature of this study is exploratory, more research about segmented running time and genre, etc. of 3D stereoscopic videos will be needed.

Social viewing has become an increasingly common viewing pattern by combining SNS use with video-watching. Accordingly, social viewing has attracted much scholarly attention, but a more comprehensive understanding of the process and effects of social viewing is warranted. For this, this study incorporated social viewing motivations, viewer satisfaction, and the continuous use intention, taking the viewer's communicative behavior into account as a possible moderator. This study conducted an online survey (N=334). Among four motivations, enjoyment, sharing and expression were significant predictors of program and communication satisfaction. Information, however, was only associated with program satisfaction but not with communication satisfaction. The moderating effects of three communication behaviors, production, sharing, and reception, were discussed in the relationship between user motivations and viewing satisfaction and continuous use intention. Production behaviors played a significant moderating role in between enjoyment, information, sharing, and communication satisfaction. Sharing moderatied information, sharing, and program satisfaction, whereas reception was not a significant moderator.

This study was carried to investigate the effects of alcohol intake on the dietary behaviors and nutrient intakes of students in university and was observed characteristics of alcohol drinking, smoking, dietary behaviors, and nutrient intakes of students. The mean of alcohol consumption was 25.7$\pm$21.7g/day and 47.5$\pm$25.8g/day, most high of high alcohol group in the male student than other groups. Smoking were high by increasing of alcohol intake. Most students had dietary problems as skipping meals, eating snack after dinner, high frequency of eating fast and instant food, and eating meals at watching TV or video. The dietary behavior problems in the high alcohol groups showed higher in the female students than the male students. Nutritional knowledge scores was no significantly different by sex and alcohol intake. The intakes of calorie, protein, phosphorous, iron, and niacin in the male students was significantly higher than those of female students. Except for calcium, vitamin $B_2$ and vitamin C, nutrients were satisfied to the level of Recommended Dietary Allowances(RDA). Nutrient intakes was not affected by alcohol intake. But intakes of calorie, protein, phosphorous, and iron were affected by sex and vitamin C intake was affected by sex and alcohol intake.

The purpose of this study was to examine the impacts of the audience and vlog creator's self-disclosure, media synchronicity (immediacy of feedback, variety of symbol set), as well as content authenticity on the intimacy between the vlogger and the audience and continuance intention of the audience. The participants of the online survey were young Chinese females, instructed to practice their routine of watching vlog and the fixed vlog channels. By the interpersonal process of intimacy model and media synchronicity theory, the results of the structural equation modeling revealed that self-disclosure (audience's disclosure) and partner responsiveness (vlogger's disclosure) form the experience of intimacy in interactions. Also, the quick immediacy of feedback, rich symbol set, and content authenticity positively impacted intimacy development. Meanwhile, intimacy enables the audience to form a continuous viewing behavior. We expect the results of this study will provide more insight into the relationship between the audience and the producer in online video content. In terms of the personal media influencers and MCN companies, this study is also suggests strategic implications.

Objectives: This pre-post quasi-experimental study was designed to investigate the effects of school based smoking prevention education on knowledge and attitude toward smoking, and the satisfaction of education among middle school students. Methods: The subjects included 94 middle school students in the experimental group. and 87 students in the control group. The educational content contained smoking refusal skills, which were taught through lectures and videos. Data collection was achieved using a self-reported questionnaire developed by the investigator. Data were analyzed with the SPSS 10.0 program including frequency, percentile, X2, paired t-test, and ANCOVA. Results: The results were as follows: 1. After the smoking prevention education, the smoking knowledge of the experimental group was significantly improved, whereas that of control group didn't change significantly. 2. There were no significant differences between pretest and post test attitude scores in both groups. 3. Refusal skill was the education content that provided the highest satisfaction for the subjects, and the degree of satisfaction was higher with video watching than with a lecture. Conclusion: Smoking prevention education for middle school students increased their level of smoking knowledge, but did not affect their attitudes toward smoking. Therefore, it is necessary to develop a more effective program, and to evaluate the effects of a long term education program with further studies.

As the subscribers of the digital cable and IPTV broadcasting are increasing, the VOD service has established a solid foothold as a profit model of the broadcasting industries. And what's more, the VOD service is emerging as a key application of the N-screen technologies. In the circumstance, broadcasting companies are trying to provide mobile services to improve the satisfaction of their VOD services usage. The paper introduces a VOD mobile app (of a domestic digital cable broadcasting), which includes the functions of promoting the VOD programs printed on a VOD guide book, directly transmitting the information (e.g., book-marking, remote-control signals) generated by the VOD mobile app to a set-top box, and watching the video contents stored in the mobile device on TV.
