  • The purpose of this study is to review the possible effect of the learning paradigm shift from traditional method to ubiquitous learning. What are the societal issues that need to be address in order to design a new pedagogical platform trending from e-learning to m-learning and now the u-learning? That without the proper study of how learning environment may affect the learning process of an individual will lead to poor quality of education. This new era of learning environment offer a big opportunity for "anytime, anywhere" learning. Thus, Lifelong learning is at hand of everyone. Maximizing the benefit of new trend will be a great help and addressing the limitations will lead to quality education.

  • 5G-based HMD technology grew rapidly in the context of the environment change of convergence technology media and mobile networks in the fourth industrial era. It has also grown into a core technology that transforms our digital visual system. However, there is no research or system that can understand and verify radical visual system changes. Therefore, it is necessary to have an engineering understanding and verification of the diffusion of HMD media imaging devices. Beyond the distinction between virtual and real, research is urgently needed on the new three-dimensional interface of the 21st century through viewer participation. For this reason, research on the algorithm structure of interactive video media using L-System is an essential process and will be a guide to understanding the virtual reality interactive environment.

  • This paper describes the new trends of fashion industry in the era of digital media and Internet paradigm, where fashion is no longer just static contents. Fashion becomes crucial and dynamic contents for infotainment, mobile Internet, and digital media. As therefore, the fashion industry could be positioned as fashion information industry and key elements of fashion communication. In the future, fashion education should be repositioned as dynamic Intermediary not only for traditional textile design, costume design, and merchandising, but also for dynamic fashion information provider, fashion communication and fashion-oriented media related to digital Information, and Internet. As a case study, we briefly describe the successful co-marketing strategies of world-class luxury fashion brands, fashion media, and Internet service provider.

  • The best value proposition for the customers of satellite-DMB (hereinafter referred to as the "S-DMB") business in an environment of fierce competition shall be securing the best killer contents and distribute them in reasonable price as a mobile contents platform provider. In an era of merging the broadcasting with the communication, although many new players tapping into the market with state-of-the-art media such as digital convergence, the key to success in the market is dependent on whether the respective digital contents providers retain competitive digital contents which suit the taste of customers. Considering such market conditions, the purpose of this study is to look over the management examples of Korean S-DMB providers which is carrying out business in digital multi-media market and opening up the market, and to analyze the management strategies of domestic S-DMB companies to be the champion in the market.

  • One of the important parts on multimedia era is acoustic ones. With increased demand of smallest multimedia products such as personal digital assistant (PDA) and mobile phones, it is necessary to develop acoustic devices which have higher performance and smaller size. Acoustic parts with various function for hearing impaired persons. This paper introduces a bone conduction vibrator (BCV) for hearing impaired persons to use portable acoustic device without additional devices. For vibration analysis of the BCV, electromagnetic, mechanical and their coupling effects are considered for the analysis. This paper shows that the development of design and analysis technique by finite element method (FEM) of BCV.

  • In this paper, due to the congestion the radio spectrum, frequency bands are shared among the satellite communication system. Therefore for satisfactory we have to design and predict with reasonable accuracy the level of interference that might exist among them, Interference among the satellite communication systems depends on many factors such as climate, radio frequency, time percentage of interest, distance and path topography, propagation delay time. This paper suggest design method of Low-Orbit satellite communication and calculates the field-of view of satellite, for the communication era using LEO. In addition, performs performance evaluation on the basis of link margine.

  • In 2019, 5G mobile communication technology will be commercialized. From the viewpoint of technological innovation, 5G service can be applied to other industries or developed further. Therefore, it is important to measure the demand of the Internet of things (IoT) because it is predicted to be commercialized widely in the 5G era and its demand hugely effects on the economic value of 5G industry. In this paper, we applied Bayesian method on regression model to find out the demand of 5G IoT service, wearable service in particular. As a result, we confirmed that the Bayesian regression model is closer to the actual value than the existing regression model. These findings can be utilized for predicting future demand of new industries.
