Recently, hybrid CDN/P2P video streaming architecture is specially designed and deployed to achieve the scalability of P2P networks and the desired low delay and high throughput of CDNs. In this paper, we propose a cooperative video streaming and active node buffer management technique in hybrid CDN/P2P architecture. The key idea of this streaming strategy is to minimize network latency such as jitter and packet loss and to maximize the QoS(quality of service) by effectively and efficiently utilizing the information sharing of file location in CDN's proxy server which is an end node located close to a user and P2P network. Through simulation, we show that the proposed cooperative video streaming and active node buffer management technique based on CDN and P2P network improves the performance of realtime video streaming compared to previous methods.

The purpose of this study was to examine the effects of age and gender on Eastern and Western cultural values imbedded in online advertising. This study conducted a survey of 180 men and women ages between 10s and 60s who lived in Seoul, Korea. They responded the acceptance degree of six online advertising emphasized three Korean traditional values and three Modern values. Research hypotheses of this study were the acceptance of cultural values in online advertising is different between ages, but similar between gender. The hypotheses were supported as the previous studies. Findings suggest several theoretical and practical implications that convergence between modern and traditional values is a more important variable to study in the research of online advertising.

This study developed the ICT curriculum focusing on apartment security guards and analyzed the actual application results. We developed the educational contents and it designed ICT job courseware for elder education by considering and that designed in consideration of the computer attitudes and physical and cognitive characteristics of the elderly. The educational program was applied to the experimental group and the satisfaction and the educational effect were analyzed through the pre and post test results. As a result of the analysis, the satisfaction level of the education program was higher than the average of 4.00 points. The elderly informal education program was examined by using the qualitative assessment test tool before and after the application of the education program. Internet self-efficacy of experiment group, improvement of internet utilization ability, usage of internet use, personal information willingness, life correction, elimination of conflict among generations, self-confidence, and internet stress increased statistically significantly. These results suggest that the "Private Expense ICT Job Training" program developed in this study can be effective for elderly informatization and can be applied to other elderly education programs and contribute to promotion.

The research background of this paper is because the u-convergence information system applying flow theory lacks the measurement of tourist satisfaction. The purpose and research method of this study are as follows. The first is the suggestion of flow relation information display format algorithm. Second, by combining this algorithm and flow theory, a pattern algorithm was created according to the content information quality and the personality type of tourists. The expected effect of this study is to derive the success factors of the u-convergence information system by generating a pattern algorithm according to the flow relationship information display format and the tourist's personality type. The limitations of this paper are limited to one area, and objectivity is poor due to the lack of data and small area. In the future, it is necessary to evaluate the effectiveness through analysis after applying the method presented to other tourist destinations. Future tasks will need to be supplemented with data from expert groups and objectivity in various regions.

The reverberation effect on the sound when producing movies or VR contents is a very important factor in the realism and liveliness. The reverberation time depending the space is recommended in a standard called RT60(Reverberation Time 60 dB). In this paper, we propose a scene recognition technique for automatic reverberation editing. To this end, we devised a classification model that independently trains color images and predicted depth images in the same model. Indoor scene classification is limited only by training color information because of the similarity of internal structure. Deep learning based depth information extraction technology is used to use spatial depth information. Based on RT60, 10 scene classes were constructed and model training and evaluation were conducted. Finally, the proposed SCR + DNet (Scene Classification for Reverb + Depth Net) classifier achieves higher performance than conventional CNN classifiers with 92.4% accuracy.

In the recent education market, Edutech technology, in which various digital technologies are grafted into the education, is being actively applied due to the 4th industrial revolution and the development of ICT. In particular, realistic experiential learning contents that can provide realistic and immersive learning in a virtual space are in the spotlight and are being expanded to each field. However, in the field of Korean medicine education, the introduction of ICT is delayed due to the nature of Korean medicine, difficulties in apprenticeship education, quantitative education, and the absence of an objective evaluation system. Therefore, in this study, we propose a digital technology application for acupuncture and acupuncture points, where practice is particularly important in Korean medicine. Various methods of acupuncture and acupoints education using AR, MR, IoT and Touch-Display Table will provide an opportunity to change the paradigm of Korean medicine education and further contribute to the globalization of Korean medicine.

Cloud computing has been evolved to support edge computing architecture that combines fog management layer with edge servers. The main reason why it is received much attention is low communication latency for real-time IoT applications. At the same time, various cloud task scheduling techniques based on artificial intelligence have been proposed. Artificial intelligence-based cloud task scheduling techniques show better performance in comparison to existing methods, but it has relatively high scheduling time. In this paper, we propose a deep learning-based dynamic scheduling with multi-agents supporting scalability in edge computing environments. The proposed method shows low scheduling time than previous artificial intelligence-based scheduling techniques. To show the effectiveness of the proposed method, we compare the performance between previous and proposed methods in a scalable experimental environment. The results show that our method supports real-time IoT applications with low scheduling time, and shows better performance in terms of the number of completed cloud tasks in a scalable experimental environment.

This paper presents the effects of fire-resistant materials on the temperature and vertical deflection of a composite beam exposed to fire through nonlinear thermo-mechanical analysis. The fire was modeled using the standard fire curve proposed in American Society for Testing and Materials (ASTM) E119. Fire-resistant materials were modeled by reducing the heat transfer coefficient from the air layer to the beam. The temperature and vertical deflection of the uncoated composite beam were measured using a laboratory fire test, and the results of the structural fire analysis were verified through comparison with experimental results. By introducing the fire-resistance effect, the reduction in the temperature and deflection of the beam for the ASTM E119 standard fire can be reasonably estimated. Based on a case study of the heat transfer coefficient, the fire-resistant effect on the thermo-mechanical response of a composite beam in the event of a fire is presented.
