This paper examines the causality issue between telecommunications investment and economic growth for South Korea by applying recently developed time series techniques. Tests for unit roots, co-integration, and Granger causality are presented. The results show that hi-directional causality runs from telecommunications investment to economic growth for South Korea. This means that increased telecommunications investment directly affects economic growth and an increase in real income also influences telecommunications investment. The study also discusses the implications of the results for addressing telecommunications policy in South Korea.

The convergence of telecommunications and broadcasting is representative of many innovative technologies in the digital environment. It has recently been emphasized as an alternative solution to overcome the on-going saturation of the telecommunications and broadcasting markets. Despite this effort, however, growth of the market and its related services cannot reach prior expectations due to lack of understanding on the real user-end. Telecommunications technology used to serve its instrumental purpose and broadcasting services usually support entertainment functions which in themselves have an inherent value. Our research questions what factors influence users' attitude and decision-making when it comes to using telecommunications-broadcasting convergence services. The research model of this paper proposes intrinsic motivator focusing on hedonic value, extrinsic motivator having utilitarian values, and perceived control as internal and external conditions. To verify our model empirically, we selected the DMB technology which is a good example of distinctive telecommunications-broadcasting convergence service.

In our study, we tried to develop and test a model that aids further understanding of the sources of customer loyalty in the 3G telecommunications service. In addition, as the 3G could be understood as an innovative telecommunications service, we assume that the impact of factors related service attributes affecting customer loyalty is moderated by the customer's innovativeness. We analyzed our research model using 3G service users' data in Korea. Our results will have significant strategic implications for firms in this highly competitive industry. Particularly, it can be useful for mobile carriers interested in customer retention management and supposed to deliver a new telecommunications service like the 4G service that is on the horizon.

The concept of e-Business has been around for more than two decades but it has not been used widely enough due to high installation and maintenance cost and complexity. In order to solve such problems, two standardization organizations UN/CEFACT and OASIS have developed an open e-Business standard called ebXML that can be easily adopted by industries. Based on the ebXML, we have developed an e-Logistics integrated platform for industries to do business electronically. The e-Logistics integrated platform was applied to B2B postal logistics industry and efficient interoperability between companies with different systems has been achieved.

As a result of the policy for enforcing the information technology led by government and the effort of companies to get over economic crisis through the reformation of business process, the ERP market is being active. However, because imported ERP products that are supplied currently are designed for standard and rationality, they have a limit to support custom processes of domestic companies in South Korea. On the contrary, ERP products by domestic companies in South Korea are unable to support a consistent methodology of constructing ERP system. This is main reason why much time and costs are consumed than that of an original plan. To succeed in ERP construction, the purpose of ERP setup must be defined. To accomplish this end, it is required to analysis business process completely and to make a plan in detail. For ERP providers, they must support a characterized ERP construction methodology and lower the construction cost by improving an ERP package easy to customize[5].

There are many researches investigating a causal relationship among service performance level, customer satisfaction, and customer loyalty. It is believed that a high service performance level increases customer satisfaction, which again has a significant effect on customer loyalty and profitability. The premise in this work is that the effect of customer satisfaction on customer loyalty may be time-lagged. This paper aims to model a causal relationship among service performance level, customer satisfaction, and customer loyalty with such a time-lag consideration. This study is conducted on the very high-speed digital subscriber lines service, which is a highly advanced high-speed internet service, and the results also be discussed.

Today, many companies realize that the effort to develop new products / services faster that customers want and continue to purchase is crucial for their survival. As the service sector is rapidly growing, one of the challenges faced by the service industries is the lack of effective methodologies for new service development. This paper proposes a systematic framework for developing new service concepts, with an emphasis on generating innovative, convergence-type service concepts from the customer‘s perspective. The framework consists of three phases-identification of customer needs (Phase I), extraction of new service opportunities (Phase II), and generation of new service concepts (Phase III). The proposed framework is demonstrated through a case study in the telecommunications industry. In the case study, a survey was conducted on ten customers to identify the latent customer needs; 61 new service opportunities were extracted; and 129 new service concepts were generated.

The evolution of telecommunications has raised the profile of many segments of the network that were not previously considered important. Until recently, basic telephony existed with the extension of passive cables without any particular user network interface. In the area of data communications, the introduction of flexible packet switching has allowed the network to evolve in a far more efficient manner. To overcome such separated network problems and business needs of both users and network providers, the integrated narrowband ISDN concept is being developed in most countries for implementation in the public switched telephone network (PSTN). The targets of ISDN, in my opinion, can be explained as follows : To the user, ISDN should provide the services at any time, at any place, through any media. To the business customer using PABX or LAN applications, ISDN should introduce customized services rapidly and also, ISDN should be developed by the modular hardware and software design approach in order for new services to be introduced rapidly and effectively. Software can be also developed by non-expert local staff to cater for adopting new user's service requirements immediately. Finally, ISDN will be able to increase business chances and benefit both users and operating companies.
