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.

This paper presents a novel method to design and implement mobile u-health system by defining the essential elements of mobile healthcare services. We choose common service elements for the proposed u-healthcare scheme and design the service platform. Especially we focus on automatic feces or urine sensing u-care scheme to prove the effectiveness of our platform. We construct the system with sensing part with a manikin and a diaper, wireless communication part with feces or urine sensing data, and coordinator system based on the u-health platform defined in this paper. Experimental results show that our scheme is useful in the area of u-care service for the handicapped, the elderly, and patients who can hardly move by themselves. In addition the designed scheme offers a realized u-care scheme with the purpose of advanced developing tools for application or service developers.

In this article, we implement a recently developed fast Monte Carlo simulation (MCS) for pricing equity-linked securities (ELS), which is most commonly issued autocallable structured financial derivative in South Korea, on the mobile platform. The fast MCS is based on Brownian bridge technique. Although mobile platform devices are easy to carry around, mobile platform devices are slow in computation compared to desktop computers. Therefore, it is essential to use a fast algorithm for pricing ELS on the mobile platform. The computational results demonstrate the practicability of Android application implementation for pricing ELS.

In this paper, we present a reconfigurable mobile platform (RMP) for user-specific applications. The RMP consists of a basic module and more than one extended module that offers specified functions to a portable platform based on the circumstances and purposes of the users. The extend module for specified purposes is connected to the basic module using a common interface that offers interoperability to the traditional interfaces. This paper gives the results of a survey to determine specifications of a reconfigurable mobile platform. Utilizing the results of the survey, we propose a prototype of the reconfigurable mobile platform to enable specialized functions. The design objective is to provide specialized functions required for user specific needs related to their age and physical condition. In addition, it can be used for mobile healthcare applications that are efficient in improving the user's health conditions by executing medical analysis and prescriptions.

This paper selected 'Line', the messenger application of Korea's leading software-based IT company 'Naver', and performed a case analysis specially in the early stages of the messenger industry. First, this study analyzed what the mobile messenger industry is and the external environment. Next, an internal analysis was carried out through the strengths and weaknesses through Naver Line's resources and capabilities. With this analysis, this study could evaluate the platform strategy, communication strategy, and the user basic strategy that Naver is carrying out. This study gave us more understanding of the mobile instant messenger (MIM) industry and understand Naver's growth strategy, which will provide great implications for the working staff of IT companies.

In this paper, the write analysis the application of basic video content of Mobil Device Platform in China and studies the future development scheme. According to the survey, as of 2019, 78% of Chinese total population is the Internet service users and application software users. Mobile Device Platform is independently developed to provide video content application services, which already have 640 million video application users from 2013 to the present. 65% of users install and use more than two video content applications. In China TikTok, Kuai Shou, MeiPai and other video content applications, not only can easily achieve simple user interface and users can directly shoot video content. These production functions is different from YouTube, a famous video platform in the United States. In the video platform market, the core competitiveness is content creation. In the future, the integration of video content of VR, AR and other video projects will expecte to further activate the video platform market.

In the case of mobile internet service using WAP it was connected to http protocol using WAP Gateway, So users take increased cost of mobile internet service. And it was generated inner security problem because it watched user information in the WAP Gateway. To solve this problem we use java language Which is independant of platform and low cost and intensely security an downloadable application. Additional , Using socket connection. Wire.Wireless Messaging system(WWMS) will connect real time between PC-Client and Mobile-Client, Mobile-Client and Mobile-Client, and so on. In this paper, as design and implementation of multi-platform wire.wireless messaging use J2Me. It will be foundation do develop various mobile application in the future.

A mobile manipulator-a serial connection of a mobile platform and a task robot-is redundant by itself. Using its redundant freedom, a mobile manipulator can move in various modes, i. e., can perform dexterous tasks. In this paper, to improve task execution efficiency utilizing redundancy, optimal configurations of the mobile manipulator are maintained while it is moving to a new task point. Assuming that a task robot can perform the new task by itself, a desired configuration for the task robot can be pre-determined. Therefore, a cost function for optimality can be defined as a combination of the square errors of the desired and actual configurations of the mobile platform and of the task robot. In the combination of the two square errors, a newly defined mobility of a mobile platform is utilized as a weighting index. With the aid of the gradient method, the cost function is minimized, so the tasle that the mobile manipulator performs is optimized. The proposed algorithm is experimentally verified and discussed with a mobile manipulator, PURL-II.
