Purpose: This study was conducted to investigate how a program using video-audio media will affect the knowledge level and compliance of the sick role of patients admitted for coronary angiography. Method: A non-equivalent control group non-synchronized design was used. Subjects were selected from patients admitted to the internal ward of a hospital in B city for coronary angiography between July 1 and September 31, 2010. Twenty subjects were assigned to the control and experimental group, respectively. Video-audio media developed by the authors was used as the experimental tool. The effects of the program were analyzed using a knowledge assessment tool and questionnaire for compliance of the sick role. The SPSS/WIN 14.0 program was used for data analysis. Result: The first hypothesis that the "experimental group receiving the program using video-audio media will report a higher level of knowledge compared to the control group" was supported. The second hypothesis that the "experimental group that received the program using video-audio media will report a higher level of compliance of sick role" was supported. Conclusion: The program using video-audio media was effective in enhancing patients' knowledge about the disease and compliance of the sick role. Thus, it can be an effective nursing intervention for patients with coronary artery disease.

Purpose: This descriptive study was to explore the factors relating to Social Physique Anxiety(SPA) in the adolescent girls(N=700). These factors included the biological(level of school[age], period of menstruation, and BMI), the sociocultural(Influence of Mass Media, [IMM], Stereotype of Ideal Female Body[SIFB], type of school, perceived figure, and ideal figure) and the BW control-related factors(experience of bodyweight [BW] control, satisfaction at the result of BW control, and motive of BW control). Method: The sample was 700 girls of the middle and high schools in Jeju-do. The data was collected by the self-reported questionnaire and processed with the SPSS Win 12.0 program. Result: 26% of the variance in SPA was explained by the biological factors(level of school) and the sociocultural factors (perceived figure, ideal figure, type of school, and IMM). SPA, IMM, and SIFB were significantly correlated with each others(r=1,65-2.92, p<.05). The mean SPA scores according to BW control-related factors were significantly different. Conclusion: This results suggest that media education is necessary to reduce or eliminate the adolescent girl's SPA. In addition, SPA needs to be considered as the important concept for the future nursing researches and interventions related to BW control.

This paper presents the design and implementation of stream control mechanisms which are necessary for the development of an efficient streaming cache server. The streaming protocols used in our implementation are the RTSP/RTP/RTCP standards. The mechanisms support both the on-demand media caching and real-time media splitting applications. The core of the stream control includes the session management, which handles the RTSP/RTCP control session and the RTP transport session, and the cache block management which efficiently manages the RTP-based cache blocks stored in the cache server. The streaming cache server with the proposed stream control mechanism has successfully been implemented on a Linux platform and it works well with the Apple's QTSS server and the QuickTime player for both on-demand and splitting media services.

Synchronization between media is an important aspect in the design of multimedia streaming system. This paper proposes a precise media synchronization mechanism for digital video and audio transport over IP networks. To support synchronization between video and audio bitstreams transported over IP networks, RTP/RTCP protocol suite is usually employed. To provide a precise mechanism for media synchronization between video and audio, we suggest an efficient media synchronization algorithm based on NPT (Normal Play Time) which can be derivable from the timestamp information in the header part of RTP packet generated for the transport of video and audio streams. With the proposed method, we do not need to send and process any RTCP SR (sender report) packet which is required for conventional media synchronization scheme, and accordingly could reduce the number of required UDP ports and the amount of control traffic injected into the network.

This study aimed to determine whether there is a significant difference in play properties in the case of media conversion through the combination of analog three-dimensional puzzles and immersive media in children's experience. Based on Roger Caillois' play theory and the contents of previous research, an experience was conducted on an experimental group and control group, and a questionnaire was prepared. The results of the correlation and paired t-test analysis showed that the play properties were higher and more evenly distributed in the media conversion immersive experience. This implies that an increase in children's fun during the immersive experience further increases their immersion, suggesting that the use of immersive media may have a positive effect on children who achieve holistic development through play and experience. We hope that this study will help recognize the difference in effectiveness through conversion into immersive media and will be referenced in various media studies that consider double-play properties.

On the basis of two premises and embodied cognition theory, the vibration tactile learning is proposed as an effective method for foreign language learning. The premises are: the real nature of language is sound and the source of sound is vibration. According to embodied cognition theory, cognition is inherently connected to bodily sensation rather than metaphysical and independent. As a result, the vibration tactile learning is: people are able to learn foreign language better by listening to sound and experiencing its vibration through touch rather than solely listening to sound. The effectiveness of vibration tactile learning is tested with two instructional media theories: media comparison and media attribute. For the comparison, an experiment is conducted with control and experimental groups. The attributes of vibration tactile media are investigated in points of relationships with the learning process. The experiment results indicate a small effect on the increased mean score. Three kinds of relationships are found between the media attribute and learning process: enforced stimulus, facilitated pronunciation, and assimilation of resonance to sound patterns through touch. Finally, this paper proposes a new theoretical development for instructional media research: an embodied cognition based media research and development.

This experiment was carried out to investigate the physical and chemical properties of growing media and to study the effects of growing media and irrigation methods on the growth of hot pepper(Capsicum annuum) transplants. The results were summarized as follows : 1. Growing media consisting of peatmoss and field soil at the volume ratio of 1 : 1, 1 : 2 showed suitable chemical properties for the growth of hot pepper transplant. 2. The germination rate of hot pepper in the sprinkler- irrigation was higher than that in the sub - irrigation. In the sprinkler irrigation, there was no difference of germination rate among the mixed growing media. 3. The growth of hot pepper transplant in the sub - irrigation was better than that in the sprinkler-irrigation. Peatmoss and field soil mixtures with the volume ratio of 1 : 1 and 1 : 2 showed the best growth condition.

The WiMedia alliance has specified a distributed medium access control (WiMedia MAC) protocol based on ultra wideband (UWB) for high data rate WPANs (HR-WPANs). The merits of WiMedia MAC such as distributed nature and high data rate make it a favorite candidate in HR-WPAN. Although QoS parameters such as the range of service rates are provided to a traffic stream, the WiMedia MAC is not able to use the QoS parameters and to determine or adjust a service rate using the QoS parameters for the traffic stream. In this paper, we propose a fair and adaptive resource allocation method that allocates time slots to isochronous streams according to QoS parameters and the current traffic load condition in a fully distributed manner. Although the traffic load condition changes, each device independently recognizes the changes and calculates fair and maximum allowable service rates for traffic streams. From the numerical and simulation results, it is proved that the proposed method achieves high capacity of traffic streams and fair QoS provisioning under various traffic load condition.

Media is a means for exchanging one's emotions or objective information in human society. Due to the spread of smart media due to the advent of digital media, media in modern society is not a simple means but encompasses the entire society in which humans live. It even took over the control function. Therefore, by examining the types and characteristics of media according to the service platform in which smart media is used, and building a big data hub for media based on this, new development and research directions for digital media can be explored. In this paper, we analyze various metadata generated through smart media and propose a plan for building a big data platform using it.
