Economists have advocated that the market competitiveness improved the firm's productivity and eventually its service quality. However, the previous researches did not provide the empirical results enough to prove that the competitiveness do improve the service quality. In this paper, we conducted an empirical research to find whether the competition induces the quality of service. The telecommunication industry was chosen since it went through the increasing competition along with a high attention. We found that competition itself does not guarantee the quality of service. It is the intensity of competition that improves the service quality. The service quality depends mainly on the competitor's competence, i.e. the intensity of competition rather than the competition itself. In sum, when we want tc improve the service quality as well as the productivity, we had better increase the intensity of competition by allowing many new strong entities.

The 1995 Informatization Promotion Act was passed to advance the national quality of life and to develop national economy by promoting informatization, forming the ground of telecommunication industry, and realizing the advancement of telecommunication infrastructure. This article was written to review whether this act's purpose was being achieved by Korean government. Even if Korean informatization policy implemetation structure is strongly centralized around the Ministry of Information and Communication, Information policies are formulated and implemented among agencies. To explain this phenomenon, I suggested the following factors : (1) The Korean government's lack of informatization experiences, (2) The political abuse of information policy, (3) the conceptual rigidity on the structure of information superhighway, (4) the absence of the basic principles for electronic government, (5) the uniformed regional informatization.

This paper examines the effects of information telecommunication (IT) capital and R&D stock variation on the growth of Korean industry, using a time series approach. Most specifically, we apply the Granger causality and impulse response analysis to our examination of Koreas industrial growth, IT capital, and R&D stocks. The Johansen co-integration test is performed in order to analyze long-term relations among these variables. This research explores the way in which IT capital and R&D stocks variation from economic shocks affects the growth of Koreas industrial sector. The effects are ambiguous, however, across industrial sectors. An impulse response function analysis shows that the effects of IT capital and R&D stock fluctuations in each industrial sector are presented for different time periods.

The mobile industry is waking up to the reality that customers buy 'services', not technology. Thekey is to deliver a variety of differentiated services today and improve them as the advanced technology becomes available. In the increasingly data centric world of the future, the emphasis will be on the provision of a range of services audio, video, data and multimedia and of course speech. As we move closer to the realization of these mobile services in the conglomeration of converged networks, new challenges are being faced by the technology and application developers as well as the service providers to design, test and integrate new products and services. Functionalities like availability, scalability, performance and compatibility have become more important. This paper discusses the new test paradigms in the mobile networks, both from the applications and the protocols perspective.

본고는 복수의 목적을 지니고 있는 통신기기의 투자에 관한 의사결정 모형을 다루고 있다.주요 분석기법으로서는 선형계획법의 일종인 목적계획법을 이용하였으며 사례로서는 1980년의 자료를 기초로 하여 1981년에 있어서 자동식교환기의 지역별 배분투자 문제를 다루어 보았다. 또한 컴퓨터를 통한 모형의 분석결과 적용 가능성을 확인하였으며 1981년도의 지역별 투자비율과 상당히 유사함을 발견하였다. 본 연구에서 제시하는 모형은 비단 자동식교환기 뿐만 아니라 통신기기 전반의 투자문제, 나아가서는 목적이 다수인 의사결정 문제에 광범위하게 응용될 수 있을 것이다.

Recently, the concern of the FTA (Free Trade Agreement) have shifted to the promotion of the professional service's trade via the bilateral and reciprocal agreement of its professional laws. In the construction industry, this policy has intended to make the standardization of the construction manager's profession in the world. The purpose of this paper is 1) first to define the general model of professions in the U.S., UK and Japan, 2) then to declare the construction manager's model of the profession in them to apply the general model of professions, and 3) finally to analyze the identity of Korean construction managers and acquirement of its construction manager's law comparing with construction manager's model of the profession in the U.S., UK and Japan.

다양한 통신 네트워크를 관리함에 따라 통합되고, 효율적인 통신 네트워크 오퍼레이션 및 유지 관리를 목적으로 한 TMN(Telecommunication Management Network)을 개발하였다. 그러나 TMN은 구현과정에서 서로 다른 플랫폼상에서 개발되어 왔기 때문에 TMN 시스템 에이전트의 클래스를 개발하고 유지하는 단계에서 여러 가지 문제점이 발견되었다. 이러한 문제점을 해결하기 위해서 본 논문에서는 CBD(Component Based Development.)를 기반으로 한 컴포넌트 아웃소싱 모델을 제안한다.

This is an exploratory research to examine the high-speed Internet access service's quality There are relatively scanty studies on telecommunication service quality such as the high-speed Internet access service. It has long been considered that service qualify are composed of process quality and outcome quality. Conducting an empirical research, we proposed that traditional outcome quality should be segmented with technical quality and outcome quality. Outcome quality is related to meeting consumer's needs to seek terminal value. In this paper, we explore to diagnose the well-known SERVQUAL's applicability to telecommunication industry and suggest some strategic and practical implications.

The various sectors of the International Telecommunication Union (ITU) have been addressing the evolution of thirdgeneration and future wireless systems in the context of a comprehensive International Mobile Telecommunications 2000 (IMT-2000) project, and within the ITU’s Telecommunication Standardization Sector (ITU-T) a Special Study Group on “IMT-2000 and Beyond” has been established to address the network aspects of these emerging wireless systems. The Special Study Group (SSG) is playing a global role in this general area, in which a number of regional standards development organizations and a variety of industry forums are also active. This paper provides background information on the SSG and describes the SSG’s ongoing work addressing medium-term issues relating to convergence of fixed and mobile systems and the harmonization of evolving IMT-2000 systems. The paper also addresses related mobility management aspects.

As needs for telecommunications services diversify, an increasingly wide range of telecommunications services is becoming available in the market. Any subscriber can find a service to satisfy his/her telecommunication requirements and competition between providers to retain heavy users is increasing. Service price reductions are one retention strategy, although price reductions for one service can affect the individual-level usage for other services. Price reductions can also be imposed on a service provider by regulation. For these reasons, understanding how price reductions affect service usage is of growing importance to the telecommunications industry for purposes of pricing and tariff development. In this paper, we develop an individual-level usage model for telecommunications services and analyze the effects on usage of a price reduction. We apply the model to age-stratified aggregate traffic data for a Korean mobile telecommunication service provider. Finally, we develop a model to support a market segmentation and price reduction strategy.
