미디어 이용자는 미디어에 노출되는 순간 다양한 심리적 반응을 겪게 된다. 3DTV 콘텐츠 역시 미디어 이용자가 그것을 시청하면서 여러 가지 심리적 지각을 하게 되는데, 본 연구는 3D 영상의 시청 시간 변인에 따른 수용자 인식에 대하여 알아보았다. 즉 3DTV 음악 프로그램을 본 수용자들이 시청시간(20분 vs. 40분)에 따라 3D 영상의 긍정적 요소인 인지된 특성과 인상, 프레즌스, 즐거움과 부정적 요소인 피로도와 부자연스러움을 느끼는데 차이가 있는지 알아보았다. 40명의 피험자를 대상으로 실험연구를 진행한 후, 연구문제를 해결하기 위해 다변량분석, 다변량공분산분석, 그리고 일원변량분석을 실시하였다. 연구 결과, 인지된 특성에서는 집단 간 유의미한 차이는 발견되지 않았지만 근접감, 선명도, 메시지 전달력 등 하위 차원에서 유의미한 차이가 나타났으며, 그 중 메시지 전달력에서 가장 큰 차이를 보였다. 인상과 관련해서는 시청시간별로 집단 간 유의미한 차이가 없었으나 하위요인 중에서는 화려함과 창의감이 시청시간 변인에 따른 차이를 보였다. 프레즌스의 경우, 시청시간별로 집단 간 유의미한 차이가 나타났고, 특히 하위차원인 시간관여에서 유의미한 차이가 가장 크게 나타났다. 즐거움에서는 시청시간 별로 유의미한 차이가 나타나지 않았다. 부정적 요소에서는 시청시간 별로 집단 간 유의미한 차이가 없었으나, 하위 차원인 부자연스러움에서 유의미한 차이가 있는 것으로 나타났다.

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.

e스포츠의 발달로 게임을 매개로 한 여러 분야의 산업들이 함께 성장하였다. 게임방송은 다양한 플랫폼을 통해 시청자들에게 도달하면서 대중적인 게임문화 확산에 기여하고 있으며, 게임이 점차 스포츠로 인식되기 시작하면서 게임방송을 실시간으로 시청하고자 하는 수요가 늘어나고 있다. 이러한 수요와 함께 최근 OTT(Over-The-Top) 서비스를 기반으로 한 글로벌 게임중계 방송채널은 빠르게 증가하고 있는 추세이다. 이에 본 연구에서는 YouTube의 Open API 분석을 통한 글로벌 게임방송 스트리밍 현황 파악 및 시청행태를 분석하고 국내 게임방송산업의 발전을 위해 실무적인 제안을 하고자 한다. 본 연구는 방송 공급자와 시청자 모두 온라인 상태에서 실시간으로 방송을 스트리밍 하는 상태인 세션을 중심으로 방송시간 및 실시간 시청자를 카테고리, 날짜, 요일, 시간대별로 나누어 분석하였다.

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.

Purpose: The study aimed to identify the effects of a newborn care education program on newborn care confidence and behavioral accuracy of primiparas in a postpartum care center. Method: This was a quasi-experimental study with a non-equivalent control group non-synchronized design. Subjects were 29 primiparas selected from a postpartum care center in D and P hospitals in Ulsan. The intervention was a newborn care education program which was composed of education with a booklet, demonstration, watching a video, and verbal encouragement. The outcome variables were newborn care confidence and behavioral accuracy. Data was collected from Feb. 1 to Mar 22 in 2005 with self-administered questionnaires and observation by researchers. Data was analyzed using the $X^2-test$, Fisher's exact test, t-test and ANCOVA. Result: The experimental group showed significantly higher score changes between the pre-test and post-test in confidence and behavioral accuracy than the control group. Conclusion: The newborn care education program showed positive effects on newborn care confidence and behavioral accuracy of primiparas in a postpartum care center. Therefore, we recommend that this program should be applied in postpartum care centers.

To investigate and analyze of the human brain-wave changes during 3-dimenslonal image load were expected to take not only an important basic information of 3-dimensional TV usage but also 3-dimensional image design. In this experiment, to analyze the difference of visual analyze handing system for which we present the 2- dimensional image having no parallex and 3-dimensional image by visual evoked potentials(VEP). 2-dimensional image and 3-dimensional image displayed on the screen through video. In the test, the time interval was one sec for presentation of stimulus considering united time of visual information of right eye and left eye during watching the 3-dimensional image also display time interval was 200 mesc for each stimulus image. Results are as follow, (1) N190 appears faster 16msec-20msec in the point of Fz, Cz, Pz, Oz when loaded 3D4 angle than 2D3 angle. (2) About of the P300, 3D4 angle(Otherwise, Oz point was reverse) and in the case of no equipment of liquid crystal shutter, there appeared PEAK near the P250. (3) There were 5% significant difference when the liquid crystal shutter was equiped and didn't, Therefore, this phenomenon show the possibility that Liquid crystal shutter influences on Visual Evoked Potentials.
