The development of various contents has been accelerated with the explosive increase of the number of internet users, the rapid expansion of wireless internet service and the pervasion of mobile terminal. Mobile service is able to offer the elastic service to anyone regardless of the place and the time. With this characteristics, this service could be extended even to the pace which the access was limited with the existing line service. The purpose of this study is to propose a system which is able to make a remote control of computer by means of mobile as an example of the production of contents for such mobile service. With this system it could be identified what kind of job a user of PC is making by mobile phone regardless of the time and place. The functions such as termination reboot, messenger, macro execution, and timer are included. The greatest advantage of the system proposed in this paper is to protect the youth, who are making an access recklessly to the harmful site, by use of mobile at my time and any place.

Mobile network infrastructure is being completed with the development of hardware and software for mobile devices. Network in mobile devices has evolved for telematics that is expanded much more than its existing concept. Telematics is compound word that is formed from the words "telecommunication" and "informatics". It means that telematics performs control and monitoring service with using mobile device resources. These services provide their services for users' requests through wired or wireless network from mobile devices and server that offers contents and network service collects management information of mobile devices. Map service is one of the preferred services for many telematics users. However, mobile map service has a limit between traffic and information sharing. Therefore it is very important to supply their information for both service provider and terminal user. In this paper, we design a new interactive sketch map using routes and information on the space to be applied effectively, and provide an extended document format that is defined to an extensible and dynamic clustering scheme to have portability map service for mobile device.

When producing a wireless web contents by using wire web contents for PC environment, we should consider how to represent lots of information being suitable with PC environment to wireless devices having narrow performance. Therefore, we propose mobile page editor for manager to select and modify specific contents with the existing wire web page. Also, we try to define an intermediate language based on DID(Digital Item Declaration) of MPEG-21 multimedia framework which defines source of converting information and wireless web contents generating at mobile editor in considering real time service problem when transcoding multimedia information in a web server into wireless device having low resolution, narrow performance of media process, memory, and so on.

Character of emoticon is considered suitable for expressivity in the digital era mixing and using contents of conversation with images in the course of having a talk with the other party in the mobile space. For the foregoing, this study carried out multiple regression analysis having factors of character attribute such as awareness, friendliness, self-expressivity and image differentiation as independent variables, and purchase intention of purchasers as a dependent variable. Analysis results show that awareness and image differentiation had a positive influence on the purchase intention, whereas friendliness and self-expressivity exerted no significant influence on the purchase intention.

The many companies and developers develop new mobile applications for serving to users. But, most of it is disappeared in a brief. Because Many applications weren't satisfy the needs of user. In this paper, it analysis to reason short life of mobile application in the smart terminals and mobile applications. Therefore, we develop dynamic user usability analysis system of applications to solve the problem. User usability analysis method is surveyed users and masters at present and then occurs high cost. In this paper, we develop dynamic user usability analysis system for real users. If usage of mobile applications upgrading, benefit of developers increased and serviced target contents to users.

We present a novel watercolor painting drawing system which can work even on low powered computing machine such as tablet PC. Most digital watercolor systems are generated to perform on desktop, not low powered mobile computing system such as iPad. Our system can be utilized for art education besides professional painters. Our system is not a naïve imitation of real watercolor painting, but handles with properties of watercolor such as diffusion, boundary salience, and mixing of water and pigment.

The importance of effective delivery of information in the mobile web is increasing in Korea, due to the growing number of smart-phone users. In this study, I took a look at the characteristics of mobile devices and the mobile web, and after researching Korea's portal websites' mobile web designs, we figured out the users' preferences of mobile web designs through surveys and interviews. To provide compressed information on a small screen, it is ideal for significant contents to show up in the state that does not require scrolling. Users preferred compact and neat designs, and menus that were made with icons that are easy to touch with fingers, in the mobile web. When receiving delivered information, users preferred not only texts but texts that were provided together with photograph images. If usability evaluations and examination of preferences are achieved together, I think it will serve as a mobile web guideline that enables efficient delivery of information in the mobile web.

In this paper, we investigate the impacts of the following four influential factors on flow in digital reading: contents, platforms, motivations, and places. The contents factor was subdivided into "news articles" and "journal papers"; platforms is comprised of "mobile phones," "tablets," and "laptops"; motivations consists of "pleasure" and "assignments"; and "home," "on the go," and "out of home" are the subdivisions of the places factor. We conducted a questionnaire survey with the study's participants and the following results are shown: 1) The flow during the reading of news articles is influenced by motivations, whereas the flow during the reading of journal papers is influenced by platforms. 2) Regarding mobile phones, motivations significantly affected the flow, whereas content types significantly affected the flow for tablets; also, laptops provided the best flow and articles can be read on the platform regardless of motivations. 3) Reading for pleasure rather than for assignments positively influenced the flow for all of the platforms. 4) With respect to news articles, the places providing flow are different across platforms. However, for journal papers, the places out of home provided good flow. For tablets, the places for flow significantly depended on the content type, which is not the case for laptops.

As the ability and technology develops for mobile devices, it now is possible to play audio files that are downloaded from the internet on the mobile devices. The audio and video files that are provided through the internet became 'podcast,' which has an auto-update service system. The major broadcasts and universities in Europe and America are using podcasts as one of their major service. Therefore large amount of Knowledge and Lecture podcasts are actively being provided. In this paper, we will analyze the Knowledge and Lecture podcasts, and suggest improving solutions.

Due to the increasing use of smart phones, using Wifi, Wibro of mobile devices spread. Accordingly, Need of using peer-to-peer file sharing between mobile devices is growing. However, common Peer-to-Peer(P2P) system is too complex and is not suitable to be applied to mobile devices. Thus, the need of research has shown to improve way in a mobile environment that has a constraints as mobility and the scope of communication. Among them, there is a Chord as contents look up algorithm. Chord is the issue. Chord as the DHT-based P2P protocol shares files, index-key and distributed key across the network. However, exist Chord doesn't consider the mobility. So, It has a lot of problems in the mobile environment. Thus, in this paper, I will try to explore an appropriate way of Chord in a mobile environment.
