Globalized cities are currently showing changes due to autonomous driving (AD). It is also maximizing globalization connections in cities where autonomous mobility is as complex as AD. The purpose of this study is to reveal that cities that realize AD and mobility will grow into globalized cities. Several cities, including New York and Shanghai, have attempted and are in progress, but failed cities are increasing. Although the technology of AD and the trust of citizens are prioritized, the city that has built the city's infrastructure is expected to be a city that has succeeded in AD. This is because commercialized cities or AVs will become hubs for mobility globalization, excluding rapid climate change or AV companies, and empirical analysis has been conducted that if AVs fail in metropolitan New York due to urban complexity (population density), urban economy size (GRDP), patents, number of consumers, infrastructure public EV chargers, and road quality. It examines whether the realization of AD by region and country affects overall national innovation. As a result, even if AV succeeds in large cities such as New York, Seoul, which has a higher population density (complexity), has a negative meaning, and a more similar Tokyo has a positive meaning. It can be seen that regional research on AV should also be prioritized in large cities such as Shanghai. This means that in order for AV to be realized in each city, the construction of AI infrastructure data must be actively changed to establish globalization of cities for economic growth as autonomous mobility.

Author outlines briefly developments of policies relating to telecommunication infrastructure and databases since latter half of 1970′s. There exist three phases. The first phase was from later 1970′s to 1985, which was an initial stage of electronic information service in Japan. In the second phase, 1985～1990, basic policy change made possible the privatization of telecommunication services and proliferation of database products and vendors, The third phase began in early 1990′s with downsizing in computer usage, wide-spreading information networks and rapid dissemination of personal computers. Then author describes offers on policy formation for "novel information infrastructure" and current situation concerning the "Internet" in Japan. Finally, tasks and problems for implementing new generation program for information infrastructure and database usage are pointed out, These are knowledge resource, cost, copyrights and cultural problems including language.

North Korea has stressed Information Technology in policy fostering science as Kim Jong-il has been interested in IT industry. In view of development of e-business in Northeast Asia, South Korea is to cooperate with North Korea. It is the time to look into the current situation, strategy and issues of IT in North Korea. Although North Korea is forced to select the development of IT Industry as growth engine, the problems in the IT Infrastructure are as follows:lack in communication infrastructure, lack in diversity of software, low level of hardware, limited use of internet. This paper deals with the IT Infrastructure of North Korea and IT and e-Commerce Cooperation, introduction of e-Trade between South and North Korea.

To data service is offered successfully including electronic commercial transaction in radio Internet, security problem should be solved. Security protocole for radio internet does certification and key exchange by leitmotif and designed because suppose WPKI(WAP Public Key Infrastructure) mainly and use certificate. Wish to discuss efficient certificate verification of PKI that consider radio surrounding hereupon.

The CDN is proposed as a solution of network bottleneck problem resulting from the rapid growth of Internet user and multimedia contents on the Internet. This paper suggests MDC and path diversity between CDN Edge server and end-user, and multicast transmission among CDN servers based on CDN infrastructure. It may be a solution for reliable and fast transmission of rich multimedia contents. These research will support to solve the unreliable transmission problem of multicasting and to create the new business models in the field of web contents.

In these days, many organizations try to manage their assets in safe way due to fast change in information-communication environment. In Korea, risk analysis and vulnerability analysis for security improvement of critical asset is booming by enforcement of Act on security of information and communication infrastructure. It is obligate that each critical information infrastructure needs to get vulnerability analysis. In this paper, we proposed Object Oriented Asset Classification model for asset analysis and risk analysis.

Recently, the Internet-based distributed/parallel computing using many of idle hosts has been demonstrated its usefulness for processings of a large-scale task and involving several important issues. While executing a large-scale task, the realtime monitoring is required for adaptive strategy of the performance and state change of host. This paper provides the realtime monitoring and visualization on global computing infrastructure called PDP(Parallel Distributed Processing) which is a parallel computing framework implemented with Jana for parallel computing on the Internet.

The Internet of Things (IoT) is the interconnection of uniquely identifiable embedded computing devices within the existing Internet infrastructure. IoT is expected to offer advanced connectivity of devices, systems, and services that goes beyond machine-to-machine communications and covers a variety of protocols, domains, and applications. Key system-level features that IoT needs to support can be summarized as device heterogeneity, scalability, ubiquitous data exchange through proximity wireless technologies, energy optimized solutions, localization and tracking capabilities, self-organization capabilities, semantic interoperability and data management, embedded security and privacy-preserving mechanisms. Time information is a critical piece of infrastructure for any distributed system. Time information and time synchronization are also fundamental building blocks in the IoT. The IoT requires new paradigms for combining time and data. This paper reviews conventional time keeping mechanisms in the Internet and presents issues to be considered for combining time and data in the IoT.

Cargo tracking issue on train transportation is challenging area because of long distance haulage, theft, terror attack and customer service. This paper aims at evaluating various cargo tracking systems in terms of cost and technology. The contents of this paper consist of the research trend of cargo tracking system in the railroad transportation and reviewing of technical alternatives in cost and service side. GNSS and RFID are reviewed as location tracking technology, Internet and Satellite technology like INMASAT and Low Earth Orbit are also reviewed as communication infrastructure. This paper selects cost and service factors in two alternatives of GNSS-Satellite and RFID-Internet, among GNSS-Internet, GNSS, Satellite, RFID-Internet, RFID-Satellite and evaluate each alternative in terms of cost and service. In a result, in terms of cost, RFID-Internet type is superior to GNSS-Satellite type, but in service GNSS-Satellite type is preferred to RFID-Internet in point of area coverage and service coverage.

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.
