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.

The depreciation cost in the telecommunication industry plays an important role not olny in calculating a corporation tax and telecommunication charge but also ill evaluating the profitability and national welfare. This paper proposes the study on LRIC model based network costing in major foreign countries and the depreciation methods applicable to telecommunication network. The simulation result from each methods could be based on determining a network costing model and legislation in the telecommunication.

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.

In this study, the conceptual model which can integrate the social process and technological teaming in technological innovation is developed and applied to the analysis of the cases on the innovation of Korean mobile telecommunication industry. Korean mobile telecommunication Industry has two peculiar characteristics. First, there have been rapid technological loaming and catching-up processes in Korean mobile telecommunication which have never been in other newly industrializing countries. Second, CDMA is the only multiple access mode which has been used in cellular phone service. It is the purpose of this study to analyse how these characteristics have been emerged during past ten years based on the suggested model integrating the social process of technology selection and technological learning.

Purpose: The purpose of this study was to propose useful suggestions by explore the effects of the Mobile Telecommunication service quality on customer satisfaction and Customer Loyalty (Focus on Moderation effect of switching barrier) in Korea Mobile Telecommunication industry. Methods: After reviewing the literature, the structural eqation modeling(SEM) conducted by LISREL 8.53 test the research model. The data was collected from subscriber of mobile telecommunication service by the questionare in Korea. Results: The results of SEM show that Mobile Telecommunication Service Quality have a positive effect on customer satisfaction, and customer satisfaction also have a positive effect on customer loyalty. And switching barrier have a moderation effect between customer satisfaction and customer loyalty. Conclusion: Mobile Telecommunication Service Quality is highly related to Customer Satisfation and Customer Loyalty, so Mobile Telecomunication Company should improve Service Quality especially price-related service quality and process/ human- related service quality. And the company need to get higher the positive Switching Barriers in order to improve Customer Loyalty.
