The competition for telecommunication-broadcasting bundle is under full steam. Even large mobile OS companies like Apple and Google are showing signs of moving into the telecom and broadcasting industry, and it is expected that competition for bundle will become even fiercer. In the light of this situation, this study will show which factors can heighten purchasing intention for bundle and lower expected-discounting rates, seeking its answer in the quality, satisfaction, and brand loyalty to core product. The results of the study show that the brand loyalty to core product affects the customer's purchasing intention positively while lowering expected-discounting rates. This conclusion suggests the importance of a marketing strategy that heightens satisfaction of existing customers who use a single item, which is just as important as strategies to induce switching behavior of the customers of other companies through competitive pricing. Also, the results suggest that rather than appeal to loyal customers through discounts, it is more effective to offer them different benefits or value.

The existence of network is indeed the single most important factor that brings about new business phenomena in the new digital economy, especially in the IT industry. Network effect refers to a phenomenon that the increase in size of the network leads to increased network value and user utility. It determines the competitive structure of an industry and the performances of industry competitors (Shapiro and Varian, 1999). The phenomenon of increasing returns and winner-take-all enjoyed by the early winner in the competition can be attributed to the existence of positive feedback which increases the value of network and induces more users into join the network (Arthur, 1996; Shapiro and Varian, 1999; Song and Lee, 2003). This research attempts to shed light on the topic of innovation and competitive strategy of network-based industries. We analyze the case of the Korean mobile communications industry, in which a shift in technological paradigm from 2G to 3G brought new changes to the competitive structure of the industry. The Korean mobile communications industry makes an ideal case for analysis since it is an industry whose value is inherently dependent upon its user network. It is characterized by the typical increasing returns, in which a monopolizing player is enjoying firstmover's network effects. Because of the existence of network in the mobile communications industry, latecomers' disruptive innovations could not outcompete the incumbent's sustaining innovations. The contribution of this research lies in laying a groundwork for future studies by introducing a numerical simulation model to analyze the complexity theory and network effect.

The substation automation is a system to remote-monitor and control electric power flow. And in line with electrification of railway, an interest in electric railway substation automation is increasing. IEC standardized IEC 61850, IEC 61968 and IEC 61970 communication protocol for the telecommunication standardization of the electric power automation industry. The recent SCADA systems in managed electric railway substations are have the problem about the compatibility with the products which fit to the international standard specification afterward. In this paper, the model of electric railway substation automation based on IEC 61850 and IEC 61970 is presented. And the method supporting the compatibility between the equipment is proposed.

In this study we tried to measure the user satisfaction with IT in small firms. Though the number of small firms is not negligible, most studies on the IT satisfaction focused on medium and large-sized firms. Using Palvia's model in 1999 we measured If satisfaction of the employee in small firms in the manufacturing and telecommunication industry. We included seven constructs such as S/W pertinence, information content and accuracy, information format, system usefulness, system continuance, and system support to measure IT satisfaction. The result suggests that the If users in small firms are generally dissatisfied with the information technology and the areas of deep dissatisfaction are system usefulness and system support. Type of business, the gender and education of the users are found to affect the level of satisfaction.

국내 이동통신 산업의 중요성 및 빠른 변화에도 불구하고, 국내 이동통신 산업만을 대상으로 한 산업연관효과에 관한 체계적인 연구는 미흡한 상태이다. 본 연구는 여타 연구와 달리 기술 및 산업 속성에 따라 국내 이동통신 산업을 크게 기기, 장비, 서비스 3가지 부문으로 분류하여 산업연관분석을 실시하였다. 또한 최근 국내 이동통신 산업이 전 산업에 미치는 영향의 변화를 파악하기 위해, 한국은행에서 발표한 2003년, 2005년, 2007년, 2009년 산업연관표를 이용하여 산업연관효과의 연도별 변화를 분석하였다. 분석 결과 생산유발효과의 전후방연쇄효과는 기기, 서비스, 장비 3가지 부문 모두 공통적으로 상승하는 추세를 보였다. 그리고 부가가치유발효과는 장비를 제외한 기기와 서비스에서 감소하는 것으로 나타났고, 고용유발효과는 기기를 제외한 장비와 서비스에서 증가 추세를 보였다. 특히 이동통신기기 분야의 고용유발효과 감소 추세는 대내적으로 자본 집약화, 기술 집약화에 따른 고급인력의 수급 불균형 현상 등과 더불어 국내 단말업체들의 해외 생산기지 이전이 국내 고용에 악영향을 준 것으로 추정된다.

Service attributes are important for customer perceptions of service quality. However, in spite of huge amount of research, the role of service attributes as satisfiers and dissatisfiers in service encounters is not understood well enough. An empirical investigation is conducted concerning a problem resolution service in the telecommunication industry. We use both qualitative and quantitative service performance data to describe and analyze how critical incidents can be used to identify and understand which service attributes are perceived as satisfiers and dissatisfiers. Our study reveals that there is a subset of critical incidents, so called critically critical incidents, which are perceived differently and are different in content compared to critical incidents. These incidents are extremely rich of information and have the possibility to reveal the real satisfiers and dissatisfiers in a service encounter.

As information telecommunication industry develops and systems get integrated gradually, the importance of embedded software is growing significantly. On the contrary, the reliability of embedded software has worsened. Accordingly, testing of software is an essential part in designing and building up embedded system and the volume of testing required is immense. This paper elaborates on design and testing model for complex embedded software, providing guidelines to collect requirements for complex embedded software.

고객관리란 고객데이터와 정보를 분석, 통합하여 개별 고객의 특성에 기초한 마케팅 활동을 계획, 지원, 평가하는 과정이다. 고객 관리는 기업에 있어서 가장 중요한 전략 중의 하나이며, 1990년대 이후로 그 중요성은 강조되어 왔다. 이러한 고객관리의 출발은 고객의 가치를 정확히 측정하는 것이며, 고객평생가치를 판단하기 위한 많은 연구가 이루어졌다. 우리는 고객평생가치 모델을 한국의 이동통신산업에 적용하기 위한 이론적 배경과 그 방법론을 분석하였다. 또한 이 논문은 이러한 과정에서 나타나는 문제점의 원인과 그 해결방안을 제시하고 있다. 이러한 연구와 방법론들은 실제 마케팅 전략에 직접적으로 활용될 수 있을 것이다.

The telecommunications industry pro-grossed as old media, but new media is going into a new era of multi-media in the 21st century. In the latter half of 1970s we saw a boom of new media as a post-telephone era began. As the machines grew to the world level(standard), facsimiles, minitels of France and word processors of Japan were developed. Today some 15 years since the advent of new media era, the progress of technology is astonishing. Advancement of technology is seen in V and U letters attached to semiconductor chips, astonishing capability advancement of light emitting lasers and photo-diodes, etc and additionally technology advancement in large capacitized light disks. Thus these technologies have made possible transmitting a broad band network and a mobile communication and digitalized broadcasting. Increased capacity of every terminal, e.g, "letters $.$ voice $.$ still and mov-ing pictures" are essential for new media simultaneous and two -way transmission.

This study aims at investigating the stylized facts of the complex system products innovation in Korea. It reviewed the preceeding studies on the innovation patterns of complex system products and selected the issues to be examined in investigating Korean case. In addition, the stylized facts of innovation patterns of Korean complex system products were suggested. The peculiar characteristics of Korean cases are as follows: Korea has succeeded in integrating foreign technologies and components into commercial complex system products and in substituting the foreign system products in the domestic market. However, it faces a great difficulty in upgrading the products to the next generation. It lacks capabilities which facilitate the evolution of system products competing in the world market.
