In this paper, we investigated the current issues on the KPAS(Korean Public Alert Service) by News analysis. News articles, from May 15, 2005 to April 30, 2020, were collected with the key word of 'KPAS' through the News Big-Data System provided by the Korea Press Foundation. The results of the content analysis are as follows. First, the issues on alert presentation were categorized by alarm sound, message content, alert level, transmission frequency, delay, reception range, time of alert, and language. Issues on inability to receive KPAS messages were categorized into authority, mobile, sending standard, mobile communication infra, etc. For the last two to three years, news on the inability issues had decreased, while news on the presentation issues had increased. This tells us that the public demand for improvement in the KPAS lies in the presentation issues. The demand for societal resolutions to the presentation issues especially on message content, transmission frequency, and reception range has soared.

The fire incident of KT's Ahyun branch occurred last year indicates that hyper-connected society led by 5G technology would be a dystopia instead of a utopia unless seamless connection of 5G service is well secured. Looking backward on 1999, we could peacefully and happily greet the new millennium by making a great effort to prevent the millennium bugs(Y2K) from causing the catastrophe such as a shut-down of banking system. Likewise, we should make a great effort to keep 5G networks and 5G service continuously working without the disruption of even just a second, which would enable us to avoid facing any catastrophes caused by the disruption of 5G service. As a way to do so, it can be considered that 5G service is designated as universal service because it has the key features of public goods like telephone and high-speed internet services.

As the concept of city changes city is viewed in the perspective of business to make profits, not in the perspective of physical space. In the case of Korea urbanization processed over the level of 80% and the formation of identity is suggested for the way to improve city competitiveness as of globalization and liberalization. Seoulentered the level of developed countries in the perspective of functions and facilities, but its image is evaluated poor because of the lack of cultural competitiveness, tourismattractiveness and service system. Dependency of public transportation which is public facilities representing city indirectly is very high, but in information service and visual systems of pubic transportation operations and management are not enough and differentiated image and loyalty are hard to find. In 2004 government of city of Seoul suggested modifications, but compared to London, Paris and Tokyo consistent system, the lack of control and management of use environment of design, excessive visual information and destruction of connection are pointed out. Therefore to solve these problems the introduction of design system is needed to develop identity after applying characteristics and regulations for using to disordered visual stuff. These procedurescan be explained as City Identity Program (CIP) and this study tries to embody city image through public transportation design system. As the study method for this the status of public transportation design system of London, Paris and Tokyo were searched and compared to that of Seoul. Based on this systematization of symbol marks per public transportation being used right now, the development of design guidelines to form identity, relation of design and the strategy of systematization per method and media were proposed.

As the amount of information is rapidly growing, and the ubiquitous urban environments are emerging, the question which information type to provide and which communication media to support is a major challenge for commercial and public travel-information service providers. The current research reports the first findings of analyses of recent data, collected in metropolitan Seoul, about the acquisition of travel information and the communication media used. The study is based on the assumption that information acquisition and choice of communication medium is strongly context-driven. The study applies CHAID analysis to find homogeneous segments in information acquisition and use of communication media. Findings indicate that transport mode and activity are important determinant of information acquisition and choice of media. The type of travel information acquired co-varies strongly with transport mode and activity. In addition, we found evidence of time of day effects. Similarly, the choice of communication medium depends on the type of travel information searched for, transport mode and activity. The results suggest important implications of managerial and policy measures, in particular the dynamic, contextual market segmentation.
