Mobile agent is a software program that provides autonomy and mobility for the users in the networked computers by deciding its own movement place. Since mobile agent does not keep up the network connection and migrate its executable code under its own control, it can be often used in the unstable network conditions such as the wireless network and the heavy traffic network. In this paper, we show that the electronic commerce system can be developed efficiently to retrieve and trade the goods in the mobile computing environment by using the mobile agent paradigm. Multiple mobile agents migrate into the market directly, then negotiate and trade autonomously relevant goods and services. The execution result and executable code of the mobile agent are returned to the home place and reported to the users. We show that the mobile agent paradigm is suitable to build the mobile electronic commerce system by designing and prototyping the mobile market system.

Purpose - This study focused on the effect of mobile app information system quality on re-use intention in the medical service trade, and examined how the Chinese, currently the main consumer of Korea's medical service trade, obtained information through mobile apps, and the status of satisfaction felt by experiencing medical services. Design/methodology - The survey period was from November 2018 to January 2019, and was conducted on Chinese who voluntarily experienced medical services. The collected data verified causality of the study model through the statistical program, SPSS.24. The results showed that the most popular medical institution through the medical service mobile app is dermatology, and the quality of the app's information system plays a mediating role in influencing re-use intention. Findings - Overall, the current trade in medical services is first accessed and acquired through mobile apps, and as a result, consumers revisit medical institutions according to the reliability of information. Comments and likes, another new form of the word of mouth that has greatly influenced revisiting in the past, are seen to be spreading through the app's medical information. Originality/value - The previous market for the medical services trade was formed by very conservative word of mouth, but now we believe that the app's information system actively influences the revisit effect. This means that apps can be used in diverse areas in the medical service trade market. In addition, the medical service market needs to further develop a mobile app environment that can reflect consumers' diverse needs, behaviors, and culture from time to time in order to revitalize the service trade. Such an app environment development will have tremendous promotional effects on the trade market and provide directions for expanding trade in medical services.

As the industrial structure of the mobile telecommunications market is transforming into the ICT ecosystem centered on smartphones, the regulatory system conforming to the new ICT environment has become the main subject of discussion in key developed countries. The EU segmented the mobile phone service into wholesale and retail. Simultaneously, the EU appraised mobile telecommunication carriers' market domination in segmented markets to continuously improve the scheme to promote competition in the telecommunications market. In Korea, also, there is discussion about adopting the EU scheme to segment the mobile phone market definition more finely and taking measures to appraise the market domination in accordance with object appraisal criteria. As such, this study analyzes whether the current criteria for appraising the wholesale termination rate market domination under the ICT's domestic mobile telecommunication ecosystem is adequate and presents the rational improvement measures reflecting the theoretically suggested evaluation factors.

Telecommunication costs have been increasing successively in Korean households. Even though there are a lot of issues related to the high charges of mobile telecommunication services, plausible solutions have not been provided yet. 99% of Koreans use mobile phones and it is the highest in the world, but charges are relatively high. This situation may be brought by the government policy that supports 'three companies system.' Even the least efficient company might sustain by a tacit bottom price policy and the government did not introduce MVNO into the market. The government can make mobile phone charge system consider cost only in a proper manner and constrain marketing costs to the rational level. And it can reduce mobile charges and rights of consumers must be respected by restraining too much complicated rates system. Fairness of mobile phone charges could be achieved by mobile phone market structure improvement through active introduction of MVNOs and reduction of excessive marketing costs. If proper market structure and policy management are secured, 30% cut of charges could be achieved. And mobile service bills may be made more acceptable if charge is based on a measured rate system according to the amount of data usage.

Since Korean government has implemented the "Number Portability System" in the domestic mobile communications market, mobile communication companies have been striving to hold onto existing customers and at the same time to attract new customers. This paper presents a competing risk model that considers the characteristics of a customer in order to predict the customer's life under the "Number Portability System." Three competing risks considered are pricing policy, quality of communication, and usefulness of service. It was observed that the customers who pay more are less sensitive on pricing policy younger people are less sensitive than older people to the quality of communication and women are more sensitive than men to the degree of usefulness of service. We expect that the result of this study can be used as a guideline for effective management of mobile phone customers under the Number Portability System.
