In the 2000s, the PC package game market has withered, but the internet based on-line game, the wireless internet based mobile game and high-powered console game market have been main stream. Among those markets, mobile game market has rapidly increased because it has 'mobility' that overcomes the limitation of time and area. But, unlike other platforms, mobile game user have to pay the higher price for download mobile game contents through the wireless internet and mobile game developer have to overcome the limitation of storage memory capacity.of mobile phone. Chiefly, the image data consume the storage capacity of mobile game contents, this paper present a technology to optimize image data for mobile game contents through analyzing type of compression method and image formats.

Mobile internet has been emerged as a key IT infrastructure while mobile internet service equipments such as smart phones have been introduced in this mobile market. These mobile internet services would be more widely spread in shorter period because the wired internet services are already popular in our life and mobile internet services have the typical characteristics that ubiquitous has. This study investigates the research model for mobile internet services based on previous researches and tests it via questionnaire. The findings are that some of features such as joy and sufficiency are statistically significant as expected.

Since the third generation (3G) mobile communication service has been launched by most mobile communication operators in Korea, the portion of data service in mobile communication service becomes one of the most important factors in mobile communication service market. In past mobile communication market, most mobile communication operators made their profit mostly from voice communication service. However, the portion of profit from data service has gradually increased based on both video phone call and mobile Internet service. In this situation, LG telecom launched the full browsing mobile Internet service. This service provides a new type of mobile Internet service platform which enables to access the World Wide Web using mobile browsers, so we generally access the Web using web browsers in the desktop computer. Under the open network structure of mobile Internet like situation, it is very important to analyze the factors which can affect the competition between mobile communication service companies. So, in this paper, we first present the current state of full browsing service, followed by the expectation of its growth potentials and barriers. Then, we analyze the advantages and disadvantage of LG telecom as a first-mover and SK telecom/KTF as followers. Finally, based on this analysis, we predict the future competition among these companies and the market.

Despite their potential value, the mobile Internet services in the domestic market have not been widely accepted as industry experts have expected. To understand why, this study uses the TAM, Technology Acceptance Model, and explores the factors affecting the usage behavior of the end-users. Based on statistical analysis of survey data, we show that social influence and perceived ease of use affect perceived usefulness, and that self-efficacy and focus significantly influence perceived ease of use. Furthermore, perceived usefulness is shown to play a significant role in explaining actual usage of the mobile Internet services. However, contrary to the hypothesized relationships, service quality, focus, and innovativeness of users turn out to have little impact on the traditional endogenous TAM variables such as perceived usefulness, perceived ease of use, and actual usage behavior. Based on these results, we attempt to provide managerial implications for the domestic mobile Internet service providers and to suggest future research directions in this domain of research.

The global mobile Internet service market is growing very rapidly, shooing drastic increases in its sales volume. Despite this growth of the market, it has not yet reached its full-grown stage, and this calls for a study on the service preference based on the characteristics of the users. As most of the existing studies in this area have centered on its technical features, they fall short of providing to the related companies any useful data to which they can practically refer in developing the future mobile services that suit for various user needs, and making plans to increase the sales volume. Based on these circumstances, this study is to investigate how the mobile contents preference is differed in accordance with the user characteristics of the Korean and Chinese mobile Internet service users. This study is also to analyze how the relationship between the user characteristics and the preferred mobile contents types is moderated by nations, Korea and Chinese. To accomplish these research purposes, this study developed a set of research model and hypotheses based on a comprehensive review of the related studies. To prove the research hypotheses, this study conducted a survey among the Korean and Chinese nubile Internet service users and performed a variety of analyses of the data collected including the questionnaires, using the SAS version 9.

Wireless Internet access shows an early-stage market that is entering a period of strong and sustained growth., reaching almost $40 billion in combined related equipment services by 2008 with equipment and services of nearly equal proportion. This explosive development is possible due to the continued growth of two of the most successful markets in history, the internet and mobile telephony. The number of global wireless internet users will incense from approximately 1.9million in 2001 to 1.3billion by 2006. Technological changes are the main factor in the emergence of what is being called the fourth generation of mobile communications.

The introduction of a mobile virtual network operator (MVNO) system is expected to increase consumer benefits, boost competition in the mobile market, utilize idle bandwidth, and expedite mobile-fixed line convergence and growth in the mobile Internet market. This research endeavors to study the optimal access charge for an MVNO system, which is expected to be introduced to the Korean mobile communications market. We found that the optimal access charge is higher in the interdependent model than in the independent model if demand for mobile phone service is based on a substitution relationship. We also found that the optimal access charge is higher than the marginal cost.

Along with the evolution of wireless internet environment, information services in mobile internet are being explosively increased. However, due to the high expense for the use of those services, it is not easy to collect the devoted customers. In order to overcome the adverse conditions, the service should be supported by a strategic application system which facilitates easier and fast service for customer's information needs than that of traditional on-line internet. In this paper, we investigate the strategy how to provide the information service under the customer satisfaction, and also consider some ways of personalization of information service and information provision in real-time. As a result of the works, we develop a system, MoSA-CRM(Mobile Service Application based on CRM) to support customer-oriented information service. We believe that the MoSA-CRM system can provide some benefits for information providers in mobile e-commerce market such as flexibility in business strategy, systematic customer relationship management, and growth in financial ability.

According to International Data Corporation(IDC) showed that PC sales for the first time ahead of the global smart phone sales in the fourth quarter of 2010. This opportunity as a smart phone application and mobile web-sites has been launched to accelerate the development of mobile services in a variety of fields. In addition to the support plan for the activation of the local traditional market from the second half of 2012 to make it easier to find information on the traditional markets of the country expanded and reorganized the traditional market-related web-site, trying to catch the foot of the youth in the online. This study is to increase the number of tourists visiting the traditional market or local residents and young people and to provide a basis for the development of mobile UI design for mobile application to investigate the local traditional market apps that are currently available.
