Accident analyses are used to identify common factors contributing to occupational accidents and to give recommendations for accident prevention. This study concerns with the accident characteristics and prevention in the telecommunication service industry. To investigate the accident characteristics, we used workers' compensation reports and employers' accident analysis reports. Three hundred and forty-five injury accidents which results in more than 4 days absence were surveyed. These data were used to investigate the accident characteristics in terms of company size, injured person's age, work experience, accident time, activity at time of accident, accident type, injured body part, and accident agency. We propose the accident prevention policy based on the accident characteristics. These results can be used to develop more effective occupational safety management policies in the telecommunication service industries.

통신산업에서의 감가상각비는 기업이 국가에 납부해야 한 법인세와 통신요금의 산정뿐만 아니라 통신사업자의 수익성 판단과 국민 후생적인 측면에도 영향을 미치므로 그만큼 중요한 문제이다. 따라서 본고에서는 이미 많은 나라에서 다양하게 개발한 고정망 LRIC 모형과 영국 이동망 LRIC 모형을 살펴보고 이를 토대로 통신망에서 적용 가능한 여러 가지 감가상각 방안을 제시해 보고자 한다. 또한 시뮬레이션을 통해 각 방안별로 감가상각비를 비교해 봄으로써 국내 통신망 원가산정방법 및 정책 결정시 유용한 정보를 제공할 수 있을 것이다.

In 1995, a group of representatives from the integrated circuits and computer-aided design industries presented a industry standard bipolar model called the VBIC model. The VBIC model includes the improved Early effect, quasi-saturation, substrate parasitic, avalanche multiplication, and self-heating which are not available in the conventional SGP model. This paper applies VBIC model for SiGe HBT device and develops an accurate and efficient methodology to extract all the DC and AC parameters of the VBIC model for SiGe HBT device at room temperature. Simulated results by the extracted VBIC model parameter are compared with the measurement data and show very good agreement in both DC and s-parameters prediction.

Although the telecommunications service industry has become a basic infrastructure component of the information and communication technology (ICT) industry, it is now losing its reputation as a cash cow due to achieving a saturation of service subscribers, especially in South Korea. With the exception of improving network speeds, network operators are experiencing difficulties in creating new innovations. Therefore, new innovations for the telecommunications service industry should be identified in conjunction with government policies for industry promotion. To examine the innovative capabilities of a specific industry, innovation system theories were used as a framework for research. However, existing innovation systems are limited with regard to explaining the openness of relationships and user participation which are general properties of the ICT industry. Moreover, as sources of innovative activity, additional values such as financial support and collaboration are more appropriate. This study presents a new innovation system based on innovation values. We analyze the telecommunications service industry and prioritize the importance of telecommunication policies within South Korea. An in-depth interview with experts based on the innovation system framework is conducted first. Next, innovation factors derived from the interview are applied within an analytic hierarchy process (AHP), leading to a prioritization of innovation factors for the telecommunications service industry.

The importance of contents industry is growing up in various industries because of internet and digital economy. Recently, contents industry is challenging to new businesses such as total service industry with digital contents. It is important to classify digital contents to use it in contents industries and information and telecommunication service industries. Previous contents classification frameworks is based on contents quality, business model and application methods. They didn't consider business processes, interfaces of business unit and interactions in contents industries. In this paper, we present core business processes in digital contents industries, a corresponding digital contents classification, and analysis method of digital contents industry.

Recently MVNO has been adopted to reform the monopoly structure of mobile telecommunication industry in Korea. MVNO is expected to not only enable mobile telecommunication industry more free, but also provide various welfare service with customers, in particular mobile payment system service. Based on TAM, this paper is to investigate the affecting factors of intention to use of mobile payment system service in MVNO environment. The results indicate that all system quality factors are significantly related to both perceived usefulness and perceived easy of use, but only stability of service quality factor is significantly related to the perceived usefulness. Perceived easy of use was found to be siginificantly related to the intention to use of mobile payment system in MVNO environment, but percevied usefulness was not.

본 연구에서는 기술의 사회적 선택과정과 기술학습을 연계시켜 살펴볼 수 있는 모델을 개발하고 그 모델에 입각해서 사례분석을 수행하였다. 모델개발과 관련해서는 기술공동체의 구조적 특성이 기술학습에 영향을 미친다는 기술학습론의 논의와 제도형성과 제도효과에 대한 조직사회학과 기술사회학의 논의를 종합하여, '기술정치'와 '기술학습'을 수행하는 주체인 기술공동체의 개념을 정립하였다. 그리고 이에 바탕해서 기술정치와 기술학습의 상호작용 메커니즘을 개념화하였다. 사례분석은 우리 나라이동통신기술개발을 대상으로 이루어졌다. CDMA기술과 GSM기술을 개발하는 국가연구개발사업과 국가표준결정 과정을 중심으로 어떻게 정책결정이 이루어졌으며, 이 정책이 각 기술공동체의 기술학습활동에 어떠한 영향을 미쳤는가를 분석하였다.
