  • In this paper, we propose method of the social scenario generation that maximize public`s participation taking advantage of a Social Network Service technology to overcome limit of scenario generation formed in existent analog space. The method is novel because digital technology was used only in storytelling, and never used in improving the quality of information introducing in scenario generation. Existent scenario generation was apt to lean in subjective thinking of individual and when handle story of professional field, there was difficulty because it was writer individual`s generation. Entrance on the stage of digital scenario generation programs was standardized form of scenario, but This limitation did not still solve. Therefore, whatever make scenario in digital space, scenario generation is still depending on only writer individual`s ideas. By method that overcome this limit, we propose social scenario generation that use SNS that writer can accommodate opinions of many people and relevant informations up to date.

  • The main active components of Panax ginseng are ginsenosides. Ginsenoside Rb1 and Rg1 are accepted as marker substances for quality control worldwide. The analytical methods currently used to detect these two compounds unfairly penalize steamed and dried (red) P. ginseng preparations, because it has a lower content of those ginsenosides than white ginseng. To manufacture red ginseng products from fresh ginseng, the ginseng roots are exposed to high temperatures for many hours. This heating process converts the naturally occurring ginsenoside Rb1 and Rg1 into artifact ginsenosides such as ginsenoside Rg3, Rg5, Rh1, and Rh2, among others. This study highlights the absurdity of the current analytical practice by investigating the time-dependent changes in the crude saponin and the major natural and artifact ginsenosides contents during simmering. The results lead us to recommend (20S)- and (20R)-ginsenoside Rg3 as new reference materials to complement the current P. ginseng preparation reference materials ginsenoside Rb1 and Rg1. An attempt has also been made to establish validated qualitative and quantitative analytical procedures for these four compounds that meet International Conference of Harmonization (ICH) guidelines for specificity, linearity, range, accuracy, precision, detection limit, quantitation limit, robustness and system suitability. Based on these results, we suggest a validated analytical procedure which conforms to ICH guidelines and equally values the contents of ginsenosides in white and red ginseng preparations.

  • The permitted limit, ${\pm}12%$, of the change in solid contents based on ASTM C 494 as an interim standard in Korea Expressway Corporation, can not reflect the kind of chemical admixture and the characteristics of solid content so that it differed depending on the admixture types. In this study, effect of cement concrete quality was investigated by solid changes which can be used chemical admixtures acceptance criteria. As a result of an evaluation of a change in the quality of concrete due to solid content, since Ligno-sulfonate based (LG) had a low water reducing ratio, the range of the change in solid content was great while Naphthalene sulfonated based (PNS) and Poly-carboxylate based (PC) High Range Water-reducing Admixtures (HRWR) had a high water reducing ratio, the permitted limit of the difference in solid content currently used as the acceptance criterion should be readjusted. As a result, it is found that the acceptable range must be managed within 10% and 5% when the solid contents less than 25% and more than 25%, respectively.

  • The purpose of this study was to examine the effect of bridging using Swiss ball, whole body vibration (WBV), and mat on trunk and lower extremity muscle activity and postural stability. The results were as follows: 1) EMG activity of internal oblique increased significantly in WBV condition compared with mat condition (p<.05). 2) EMG activity of rectus femoris and medial gastrocnemius increased significantly in Swiss ball condition and WBV condition compared with mat condition (p<.05). 3) The muscle activity of medial hamstrings increased significantly in Swiss ball condition compared with mat condition (p<.05). 4) The limit of stability in three groups increased significantly in all directions after 4-week intervention (p<.05). 5). There were no significant differences in the limit of stability among three groups after 4-week intervention (p>.05). Therefore the trunk and lower extremity muscle activity increased in Swiss ball and WBV conditions, and postural stability was improved in three groups after intervention period.

  • The purpose of this paper is to analyze Hirata Oriza's three plays, "Scientific Minds," "Monkeys on the Northern Limit Line" and "Balkan Zoo" with Lyotard's postmodern scientific view. Liotar, who claims that science and narratives follow the rules of their own pragmatic use, talks about the incommensurable parallelism between the two. Hirata Oriza points out that humans rely on narratives in the postmodern world. This paper analyzes Hirata Oriza's plays in three aspects. First, in the postmodern world where the master narrative has disappeared, it identifies the point where the boundaries that define the identity of human beings under the lost and developing science technology are fading. Second, we look at the pattern in which the parallelism between scientific knowledge and narrative knowledge is constantly diluted due to the characteristics of humans who understand the world by leaning on narrative. Finally, the aspects of small narratives are idetified, raised by individuals to comfort themselves toward a world where the master narrative disappears and is justified only by maximizing performance.

  • Modern society is the era of convergence, and storytelling requires the necessity of storytelling in which two types of data types, emotional stories and information, are fused. Particularly, in the case of VR contents, the user must directly participate in the content and select the information through the process of freely searching $360^{\circ}$ space, so that the user can interact with the content immediately. Therefore, there is a limit to access to the existing storytelling method, and it is considered that the implementation of 'convergent storytelling' that meets two areas of sensitivity and information is considered to be an urgent genre. In this paper, we focus on the spatial characteristics of VR contents, and then, as a way to effectively implement 'convergent storytelling' in VR contents, We propose a custom system by organizing the type into a circle structure. Based on this, it is expected that the technology will be developed into a research of a personalized system that meets two areas of emotion and information by utilizing the context recognition process for VR content and interaction in the fourth industrial revolution era.

  • The core purpose of the system proposed in this paper is to help learners pursue proactive and self-oriented education by allowing learners to proactively configure their own content, that is, learners no longer have to be restricted by prescribed sequence of lectures. Although a variety of standardization and Learning Management System (LMS) were produced to develop and effectively manage web contents in response to active diffusion of internet application, practical changes to assist online learners are not yet to be found. In this paper, I would like to introduce a LMS that can support self-leading education by providing various types of learners at Virtual University with delicately organized educational contents for maximum efficiency. The system allows a learner to select a lecture or a chapter which has been presorted to meet his educational needs and intellectual ability. In general, most LMSs cannot meet every individual's educational needs because they structure their programs by letting learners simply choose from a list of available lectures at prescribed level or difficulty. However the Self-Leading LMS eliminates such boundaries by allowing learners to choose contents and difficulty within the limit set by their own educational competence.

  • Recently, there are several active and vibrant studies on Realistic Media that try to provide the immersion and the presence by adding sensory effects to video. Because existing sensory effects on Realistic Media are produced through experts and automation programs on sensory effects, there is a limit to fill up the gap of user satisfaction which comes from the diversity of cybernauts. In this paper, we propose a method to improve the satisfaction with sensory effects by collecting and analyzing user's response information, and applying the result to the attributes of sensory effects. The proposed method allows you to produce the Sensory Effect Metadata effectively by analyzing users' biometric data and subjective satisfaction with realistic media experience, measuring the weighted value to revise the effects, and applying to the attribute of sensory effect. The experimental result shows that the proposed method improves the satisfaction with realistic content by generating the revised Sensory Effect Metadata in response to user's experiential feedback information.

  • Internet-based client/server architecture of Contents Delivery System suffers from frequent disconnections and security treats caused by dependency of the server or overload. But, We reached the limit to the increase of the server because a contents quality enhance and Internet user explosively increase. Therefore, a P2P based computing methods are used for sloving these issues. In this paper, We implement and design the Education Content Delivery System for cyber education system using idle Computing Power in P2P computing to share computing resources. We implement not only Internet infrastructure but also satellite infrastructure system, and designed to transfer real-time or non real-time contents.
