Since Korean mobile communication companies each use different mobile platforms, developers must configure and translate their game contents to run under each of the platforms so that they can be serviced correctly. Nevertheless, such translation tasks require lengthy times and costs. This is one of the reasons why a variety of contents could not be provided. In order to mitigate such difficulty, this paper implemented an automatic mobile contents translating system that automatically translates mobile C game contents of the GNEX platform to mobile java contents of the WIPI platform. The GNEX C-to-WIPI Java automatic contents translation system helps minimize the amount of time and cost required in servicing contents to different mobile communication companies by promptly translating a platform-specific-content to run under other platforms. Also, the automatic translation and servicing of existing contents increases the reusability of these contents and also the productivity of new contents thereby offering users with a more variety of games.

The development of IT related technology has made it possible to offer 'Any Time, Any Where, Any Service' to the users and internet-based service became accessible while on the move through wireless internet service. Moreover, the development of various wireless contents has been provided diverse ioy and convenience to life. However, the existing wireless contents had been subordinate to the wireless internet platform because it had not been set up for a standardized environment. Therefore, repeated developments of contents have been causing waste of resource, time and manpower. This paper aims at suggesting WIPI-bases artificial reefs search contents which have become independent from platform by using JAVA. Artificial reefs facilities are a government project for increasing the revenue of fishermen but only few fishermen know the information about the location of artificial reefs and most of them are not aware of the location of these facilities. There(ore this thesis plans to develop WIPI-bases artificial reefs search contents to provide information such as the location, the depth, and the bottom material to anglers and those fishermen who do not know the location of artificial reefs so that the fishermen can have the opportunity to increase their revenue and also the opportunity to catch a big fish for anglers.

This study comparatively analyzes the cases of CDMA (Code Division Multiple Access) and WIPI (Wireless Internet Platform for Interoperability) to find out the success and failure factors of technology policies in the field of mobile communication industry. For this purpose, the two cases are analyzed through a new analysis framework, which is made by combining System of Innovation with a range of variables derived from precedent studies, such as external environment, institutions, technological system, governance structure, and interactions of actors. The results of analysis show that in the CDMA case, the following factors led to success ; Korea made good use of the external opportunities in the early stage of digital communication technology and adopted a suitable governance structure for the technological system. Main actors in Innovation System had strong will for success and engaged in cooperative interaction. For the WIPI, however, the timing of technology policy was inappropriate and a unsuitable governance structure for technological system was chosen because of path dependence. The Innovation System failded to respond efficiently to the situation where conflicts among actors had intensified, US trade pressure had increased and innovative smartphones emerged. The results of this study provide the practical implications for the success of technology policy; namely it is important to choose a governance structure that suits the external environment and characteristics of technology and to activate cooperative interactions among actors in Innovation System.
