This paper deals with the viewing rate trends of digital media service special reference to terrestrial real time broadcasting of IPTV. In a few years, TV viewership of young people is decreasing, the audience viewing rate of the terrestrial broadcasting which is the representative of the media decreases, and the change of the broadcasting industry is progressing. Especially after the terrestrial broadcaster 's VOD holdback was extended, the viewer' s movement on the competitive channel & mobile media was rapidly progressing. Researcher assumed that the viewing rate of the terrestrial real-time broadcasting has influenced the comprehensive channel, CJ E&M subsidiary channels. As a result, researcher verified using statistical methodological time series analysis and regression analysis. Based on these results, researcher expects media players to prepare policies for viewers' satisfaction and symbiotic growth of markets.

Aging is one of the major tasks that our country should resolve. To deal with aging problems, many countries have introduced various new concepts such as active aging, productive aging, and successful aging, well aging and anti-aging. This study suggests a new concept, digital aging, to tackle aging problems, and we use this concept to explore the new policy and policy areas for aged people. Since this concept is not well defined yet, this article focuses reviewing existing research literature. Instead of focusing the negative aspect of aging, this study investigates how to use the digital technology to build such images that the old man can be continuously learning, active and productive.

Business organizations intend to survival in the global market with a dramatically changing environment, an efficiency management process is obviously needed. The traditional management ways can not follow the steps of the new world. In another word, leaders now have to focus on building a new employee-employer relationship. Globally, as the economic recession continues and consumption shrinks, companies face a lot of difficulties. Companies will, eventually, fall behind in the market unless they respond to this constantly changing business environment and market, systematically. Accordingly, the importance of leadership can be said to be highest ever. This study inquired into the preceding research on servant leadership and carried out an empirical analysis with the workers in the service industry. As a result of the analysis, it was found that servant leadership had positive impacts on organizational commitment and organizational citizenship behavior, and that the boss's trust affected the impact of servant leadership on organizational commitment.

As industrial technology advances, convenience is also being developed. Many people living in big cities are commuting using transportation such as buses, taxis, cars, etc. and enjoy leisure, so research is needed to reduce the damages caused by traffic accidents. This study deals with estimating road-level rainfall in real-time. A rainfall observation data and radar data provided by the Korea meteorological administration were collected in real-time to create an integrated database, which was estimated as road-level rainfall by universal kriging method. Besides, we conducted a study to interactively visualization of mash-up road traffic information in real-time with integrating rainfall information.

This study investigated the factors affecting the satisfaction of augmented reality (AR) fashion application focusing on user experience. The survey was conducted on 280 Chinese users who had used AR fashion applications. The results are summarized as follows. User experience had a significant effect on presence, flow, and satisfaction. Personalization service also increased user satisfaction. Presence influenced flow which enhanced satisfaction, indicating that presence had an indirect effect on satisfaction through flow. The results are expected to provide strategic implications by identifying factors that should be considered to help consumers experience products and improve satisfaction with applications in various industries focusing on augmented reality technology.

The purpose of this study is to analyze bibliographic information of Busan and other cities' reports for urban development initiative and identify the strategic fields for future smart city plan. Text mining method is used in this study to extract keywords and identify the characteristics and patterns of information in urban development reports. As a result, in earlier stage, Busan city focused on service creation for industrial development but there are lack of discussions on the linkage of information systems with ICT technology. However, recent urban planning in Busan contained various contents related to integrated connections of infrastructure, ICT system, and operation management of city in the specific fields of traffic, tourism, welfare, port/logistics, culture/MICE. This results of study is expected to provide policy implications for planning the future urban initiatives of smart city development.

Recently, IoT technology has great attention and plays a key role in 4^th industrial revolution in order to design customized products and services. Additive Manufacturing (AM) is applied to fabricate IoT sensor directly or IoT sensor embedded structure. Also, design methods for AM are developing to consolidate various parts of IoT devices. Part consolidation leads to assembly time and cost reduction, reliability improvement, and lightweight. Therefore, a design method was proposed to guide designers to consolidate parts. The design method helps designers to define product architecture that consists of functions and function-part relations. The product architecture is converted to a network graph and then Girvan Newman algorithm is applied to cluster the graph network. Parts in clusters are candidates for part consolidation. To demonstrate the usefulness of the proposed design method, a case study was performed with e-bike fabricated by additive manufacturing.

The purpose of this study is to improve the curriculum to revitalize beauty tourism by analyzing the difference in importance and satisfaction of the beauty tourism curriculum. And online and offline surveys were conducted for workers in the beauty tourism industry, and IPA analysis was conducted using 208 valid samples. As a result of the analysis, it was found that there was a difference in the importance and satisfaction of all educational contents. And than, it was found that there were no educational contents that needed improvement, and the training courses that required continuous maintenance were field practice, major practice, service and manners, customer consultation, customer management, marketing, and interpersonal relationships. Education content with low priority was found to be foreign languages, multicultural understanding, tourism, and beauty management. Based on the results, directions for improving the curriculum for revitalizing beauty tourism were suggested.

Due to COVID-19, many paradigm shifts in existing manufacturing facilities and the expansion of non-face-to-face services are accelerating worldwide. A representative technology is digital twin technology. Such digital twin technology, which existed only conceptually in the past, has recently become feasible with the construction of a 5G-based network. Accordingly, this paper designed and implemented a part of the USB process to enable digital twins based on OPC UA communication, which is a standard interlocking structure, between real object objects and virtual reality-based USB process in accordance with this paradigm change. By reflecting the physical characteristics of real objects together, it is possible to simulate real-time synchronization of these with real objects. In the future, this can be applied to various industrial fields, and it is expected that it will be possible to reduce costs for decision-making and prevent dangerous accidents.
