Six sigma activities in an information and communication technology company in Korea are introduced. Korea Telecom(KT) was a public company for a long time and became a private enterprise not long ago. Although this company adopted many innovation programs, they were not effective because of the company's characteristics : long-time government-owned and information service industry. This paper describes the reason why KT introduced six sigma, some implementation strategy, and key factors to successfully deploy it. This paper is expected to be helpful to public or service industry in which it is very difficult to implement innovation activities.

In the telecommunication industry, estimation of the cost of network facilities is very important since depreciation cost of the facilities accounts for a large portion of the product cost. Moreover, cost estimation in the industry becomes more difficult because of increasing indirect cost upon digital convergence, expanding multi-purpose facilities, complexity of service product, etc. Nevertheless, not much seem to have been done in improving estimation methodology of the cost of network facilities. As a result, the quality of cost information on network facilities has deteriorated, and now even decision-makers in the industry dismiss the information. Recently, two major telecommunication companies adopted a new network cost estimation method to deal with the issue. In this paper, we study the concept of new cost estimation method and the procedure to develop and apply it. We also suggest the method to carry out the cost allocation using Matlab which is more efficient and time-saving than other commercial cost calculation packages.

The purpose of this study is to categorize group of firms by using characteristics of technical innovation in telecommunication industry and to identify relationships between types of technical innovation and such contingency factors of technical innovation. The major findings of this study are summarized as follows; First, Type 1 Group (Innovative Industry Leading Group) tends to use innovative and market differentiation strategy and has more innovative C.E.O's management style and innovative culture. Second, Type 2 Group (Dependent Group on Market Change) tends to use market differentiation or cost leadership strategy and has a more conservative C.E.O's management style and non-innovative culture. Third, Type 3 Group (Small Technology Intensive Group) tends to use focused innovative strategy and has a more innovative C.E.O's management style and innovative culture. Fourth, Type 4 Group (Non-Innovative Group) tends to use focused cost leadership strategy and has a more conservative C.E.O's management style and non-innovative culture.

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

정보통신 국가표준에 있어서는 무엇보다 공공성이 중요하며, 국가표준의 주요목적은 국내의 정보통신서비스를 비롯한 각종 정보기술 관련 산업체 및 연구원들의 사기를 앙양시키고 효율적으로 정책을 수립하고 이를 공지하여 관련 산업체와 연구원 및 특허권자들의 권익을 보호해야만 한다. 따라서 본 연구에서는 현행 정보통신 표준화를 활성화시키기 위한 국내외의 연구소 및 정책을 비교분석하고 정책을 제안하고자 한다.

투자보수율은 통신정책에서 사용하는 가장 중요한 원가요소의 중 하나이다. 본 연구에서는 현행 투자보수율 산정방법과 산출과정의 문제를 검토하고, 합리적인 투자보수율 산정을 위한 개선방안을 제시하고자 하였다. 먼저 산출방법의 개선을 위해서는 시장프리미엄산출시 벤치마크법을 사용하여 경기변화와 인플레인션으로 인한 결과 왜곡을 방지하고, 부채프리미엄가산법을 사용하여 타인자본 산출과정에 발생하는 정확성의 문제를 개선하며 최적자본구조법을 적용하여 급격한 시장변화에 의한 자본구조 변화의 문제를 줄이도록 하는 방안을 제시하였다. 산출과정을 개선하기 위해서는 투자보수율을 산정 주기를 1년으로 하여 시장 변화의 속도가 빠른 통신 산업의 특성이 반영되도록 할 것을 제안하였다. 또한 투자보수율의 산정주체를 규제기관이 아닌 기업으로 변경해 규제기관과 피규제기업 사이의 정보비대칭으로 인한 투자보수율 산출비용을 감소시키고, 기업별 투자보수율을 산정할 것을 제시하였다. 본 연구에서 제시한 투자보수율의 개선방안은 앞으로도 지속적으로 시장의 변화를 반영하여 개선할 필요가 있을 것이며, 투자보수율 산정방법 자체에 관해서도 합리적이고 투명한 산출기준이 마련될 수 있도록 추가적인 연구가 필요하다.

본 연구는 이동통신시장의 주요통계지표를 이용하여 이동통신시장의 산업수명주기(Industry Life Cycle)(태동기-성장기-성숙기)를 유형화 하고자 하였다. 분석 모형은 2단계로 구분되며, 1단계 분석에서는 이동전화보급률을 기준으로 이동통신시장의 발전단계를 유형화하고, 2단계 분석에서는 주요통계지표를 비교분석하여 이동통신시장의 발전단계별 시장특성을 제시한다. 1단계 분석결과 군집분석을 이용하여 이동통신시장의 발전단계(태동기-성장기-성숙기)별로 국가군이 유형화되었으며, 발전단계별 군집은 국가경제의 발전수준과 상관관계가 있는 것으로 파악되었다. 2단계 분석결과 주요통계지표에 대한 비교분석을 통한 이동통신시장의 발전단계별 시장특성은 다음과 같다. 첫째, 시장구조지표 중에서 HHI(시장집중률)은 성장기와 성숙기보다 태동기에 매우 높은 것으로 나타났다. 둘째, 시장효율성지표에서 ARPU(사용자당 평균수익)와 RPM(분당수익)은 태동기에서 성장기, 성숙기로 갈수록 높았다. 셋째, 시장성과지표인 EBITDA 마진율은 태동기에는 매우 높지만 성장기, 성숙기에는 상대적으로 낮은 것으로 파악되었다. 결과적으로 이동통신시장의 주요통계지표를 이용하여 특정 국가의 이동통신시장이 산업수명주기 상 어떤 위치에 있는지를 파악함으로써 시장환경 변화에 대응할 수 있는 정책적, 전략적 시사점을 찾을 수 있었다.

Including the Qualfication of Staffer required for Commuinication, the National Law of Professional qualification is a basic law for supply with manpower of high growth industry, and it is aiming at perfect the national Policy Concerned improvement for education and training of staff, carrying out of state examination for qualification and getting an occupation or application for special qualification. This law has established a management committee for qualification system in The Ministry of Science and Technique ROK, and authorized competence Minister according to kind of special qualification aiming at getting employment, practical use and courteous treatment in society and economy for national qualification, and also regulated their each official duty. A qualification of staffer required for communication is an administrative measure giving as occupational certificate after some examination for knowledge, technique and faculty in vocational ability to adapt to intrinsic of telecommunication. This certificate has the cause of an attribution of over the sphere of telecommunication, and so it has been originated in international situation, and then some of them is forced by international law, otherwise it be in common use between the nations. The Characteristic and orthodox of communication certificate has been succeded continually in company with development of telecommunication and the appliable field of them is specified, but the sovereign power of nation is approved by ITU that she can extent the applicable position for communication certificate and coordinate the utility of qualification for telecommunication value. Korean telecommunication law excepted the application of communication certificate in public communication field. It is unreasonable and even disobeyed against the theory of communication science and intrinsic of telecommuncation. Therefore it should be corrected immediately and then communication certificate have to accept in the public communication field at all, if so, the application field of communication certificate can have more than useful extenxion such as administration measure should be achieved by the management committee for qualification system in Ministry of Science and Technique and competemce Minister appointed according to special kind of certificate and the administration have to manage by the method and proccess caused by communication science or cooperative system between administration, industry, education and science. And, then, every acquisitor of qualification also has to try to perfect his vocational duty sincerely and to promote each self-realization.
