The Internet is now an ubiquitous technology in business and possesses the potential to make the concept of value chain into an attainable reality. We posit that the way the Internet is utilized, the extent of the Internet's impact on business performance, and the extent the firms are prepared to take advantage of the Internet varies from country to country and from industry to industry. Based on data collected from 54 firms in the U.S. and 135 in South Korea, we compared the two countries (U.S. and South Korea) and two major industry groups (manufacturing and service) regarding the pattern of Internet utilization on the Internet from a value chain perspective. The findings show that U.S. companies utilize the Internet more extensively in such areas as human resources management, automation, sales, and advertising than the South Korean counterparts. However, we did not find a statistically significant difference in the way the two countries use the Internet within a value chain model. We also compared Internet practices by industry sector (i.e., service vs. manufacturing) within each country. The results show that firms in the service sector tend to use the Internet more extensively than the manufacturing counterparts in both countries. Particularly in Korea the difference between the sectors was significant in the extent to which they utilized the Internet to support such business activities as inter-organizational alliance, communication, and marketing.

Recently, RFID(Radio Frequency Identification) application technology is the core of ubiquitous technology. this research examines the factors for adopting the RFID application technology together with factors for adopting the related information system such as ERP, SCM, EDI by researching relevant literature. this research attempts to derive the factors for adopting RFID application technology by using the Delphi Method. The factors for adopting the information technology of the above-mentioned three areas totaled 116 adoption factors. Based on these 116 adoption factors, the factors for adopting RFID application technology were to be derived. A total of 27 adoption factors were derived in the first Delphi investigation. Of the total 27 adoption factors, final 9 adoption factors could be derived by conducting frequency analysis and relative importance analysis. In other words, 9 adoption factors that were derived last were found to be the cost related to tag, relationship with customer firms, compatibility of technology, information technology-based structure, trust and coordination between business firms, intensity of competition within the industry, the standardization of RFID technology, the top management's support and participation degree of client companies. When business firms try to adopt RFID application technology afterwards, concrete and close examination from this point of view was found to be necessary.

This research connected network equipment, including CCTV, PAGA, IP-PBX, and Legacy, in order to enable the operation and configuration of internal IP-based network equipment in maritime plants and vessels, both in the field and from remote places, and to allow for the support of remotely controlling such equipment. It also realized an operating program for the integrated network equipment management system to enable the monitoring and control of equipment status, operation condition, and notifications from distant places. By applying the operating program to satellite stations and vessels sailing on the sea, a performance test was conducted to evaluate data loss and transmission/reception delay in the communication section between the land and vessels. As a result, this research verified the normal operation of CCTV control and of real-time monitoring and control of the network equipment, including PAGA, IP-PBX, and Legacy under the FBB and MVSAT environments. It was observed that the transmission of CCTV video images with a large volume of data as well as the transmission and reception of voice data were found to be slightly delayed, indicating the need to develop technology to compress and convert data for real-time transmission and reception.

An e-business client application in ubiquitous mobile computing environment may become disconnected from the enterprise server due to broken communication connections caused by the limitation of mobile computing environments(limited battery life of the mobile device, low bandwidth communication, incomplete wireless communication infrastructure, etc). It Is even Possible that mobile client application Intentionally operates in disconnected mode to reduce communication cost and the power consumption of the mobile device. We use “data hoarding” as a means of providing local autonomy to allow transactions to be processed and committed on the mobile host despite of disconnection. The key problem to this approach is the synchronization problem that serialize potentially conflicting updates from disconnected clients on master objects of the server database. In this paper, we present a new transaction synchronizing method that splits a transaction into a set of independent component transactions and give the synchronization priority on each component taking the possibility of use and conflicts in the server into consideration. Synchronization is performed component by component based un synchronization priority. After the Preferred component of a no bile transaction succeeds in synchronization with the server, the mobile transaction can pre-commit at server. A pre-committed transaction's updated value is made visible at server before the final commit of the transaction. The synchronization of the component with low synchronization priority can be delayed in adaption to wireless bandwidth and computing resources. As a result, the availability of important data updated by mobile client is increased and it can maximize the utilization of the limited wireless bandwidth and computing resources.

In this study, we examined the sense of tradition and cultural traditions which make up Japanese ubiquitous society. These include the traditional elements which affect the lives of contemporary Japanese people. In this research we looked for various media (mobile phones, blog, characters goods, cinema) which appeared in the traditional elements. The results of the study are as follows: The traditional elements which affect contemporary Japanese lives include modern devices such as use of anonymous "blogging", mobile phones "youth culture"(especially by males), and "cute" character vocabulary use (especially by females), while traditional values(yakuza, sumo, human relationships) are represented in Japanese cinema. Through this study, we have found the points where traditional Japanese culture and cultural sense have been reinterpreted and affected both directly and indirectly through modern media. This study contributes to cultural research by delineating the various stimuli to consider for successful content service adoption in a global setting, which can account for differential impacts across regions. The results not only help develop a sophisticated understanding of customer behavior theories for researchers, but they also offer useful knowledge to those involved in promoting culture content to potential purchasers.
