To provide convenient life, we consider the situation of using the smart phone to control smart TV and PC in home and office. In this paper, we design the interworking platform between smart TV, smart phone and PC, and implement their applications. Our smart phone application controls the smart TV and PC, where our smart TV application communicates with the smart phone and PC can be booted by the login and password information given form our smart phone application. We hope that our platform design and application implementation will be contributed to be a foundation of interworking between various smart devices in the near-future real smart life.

This study focused on mobile trend in diffusion of smart phone. Presently, it has been evolved from digital nomad to smart nomad. Smart nomad era is based on digital technology with mobility and being smart. Smart nomad that is made up high-end device and intellectual content has changed structure of industry and life style. Smart phone is a core key in smart nomad era. In 2010 smart phone has been distributed about 2.5 hundreds million which is 20% of whole mobile phone sales and the volume of smart phone sales will be getting bigger and bigger in near future. Although, there are various reasons for success of smart phone market, this research focused 4 reasons: first, development of mobile device, second, evolution of mobile content distribution, third, support of government system, fourth, success of Docomo i-mode and Apple i phone. Smart phone will grow up more rapidly. Smart phone eco-system will be more competitive in the world. In Korea, smart phone eco-system also will be very competitive. For success in the middle of this competitive environment, Korea should lead the competitive phase with development of ability of creation software and content, construction of various partnership and evolution of next generation technology and service.

There are three ways how to extract forensic evidence from mobile phone, such as SYN, JTAG, Revolving. However, it should be a different way to extract forensic evidence due to the differences of their usage and technology between them(mobile phone and smart phone). Therefore, in this paper, I will come up with extraction method that forensics evidence by search and seizure of a smart phone. This study aims to analyze specifications and O.S., backup analysis, evidence in smart to analyze for search and seizure of a smart phone commonly used google android and windows mobile smart phone. This study also aim to extract forensics evidence related to google android and phone book, SMS, photos, video of window mobile smart phone to make legal evidence and forensics report. It is expected that this study on smart phone forensics technology will contribute to developing mobile forensics technology.

This study was to examined the acceptance of communication for people through smart phone focused users of smart phone. The results were as follows. First, smart phone's mobility influenced positively on attitude toward the transmission of government policy. smart phone's personal appropriateness influenced positively on awareness toward the transmission of government policy and usefulness toward the transmission of government policy. And smart phone's usefulness influenced positively on usefulness toward the transmission of government policy. Second, smart phone's ease of use influenced positively on awareness toward the transmission of government policy. smart phone's security influenced negatively on awareness, usefulness, attitude toward the transmission of government policy. smart phone's connectivity influenced positively on awareness toward the transmission of government policy. Third, usefulness and attitude toward the transmission of government policy through smart phone influenced positively on acceptance intention.

Recently the market of smart phone applications grows very fast. And users want more various and rich experiments using enhanced smart phone functions. But the development of smart phone applications is not an easy job. Specially to control smart phone sensors can be realized by using each native programming languages in experts level. Moreover the process needs separate development based on each smart phone OS. Development of the Web-based smart phone application using Web Common APIs, known as 'WebApp', is one of solutions to overcome these problems. The method includes interface constructions with HTML, and Web Common API calls and accesses to smart phone device APIs with Java scripts. In this paper, the experience in development of the smart phone e-book application is introduced, which is implemented with comport and OS independent WebApp development method.

We propose an interworking architecture between a smart TV and a smart phone. This architecture provides control mechanism for the newly adopted App on Smart-TV with smart phone. The general method connecting between a smart phone and a mobile AP is very carefully complex and troublesome procedure. The mobile AP transfers data from a smart phone to a smart TV after getting the connection. Connecting procedure between a smart phone and a mobile AP is therefore necessary operation. We worked out the new procedure and control method that acquires some information from Near Field Communication or Quick Reference codes for connecting between a smart TV and a smart phone. Our proposed architecture was confirmed practical possibility as user-oriented automatic connection and simple manipulation for control a kiosk or various display equipment.

With the rapid development and diffusion of smart phone applications, mobile users are able to use various useful mobile services in humdrum life. Especially, interesting applications like QR code using camera module in a smart phone are developed continuously nowadays. We realized that the size and shape of shooting objects taken by a smart phone camera module are very different according to their types and versions of the android-based smart phone in the process of developing applications for measuring the shooting object using camera module of a smart phone. In this paper, we investigate the major differences among smart phone types and system versions when we take specific object with camera module of smart phones, analyze the various characteristics of camera modules that influencing the real size of the shooting object taken by a smart phone, and apply them to the development of the smart camruler application.

A positioning based service uses one's position information with GPS. This application also use the position based characters and change the smart phone to the vibration mode at the registered position. If the user register some places to be vibrated in the smart phone, the smart phone will be automatically changed to the vibration mode as the registered position is same with the position of GPS in the smart phone. If the smart phone is being leaving some distance from the position, the phone will be released from the vibration mode. Therefore, this paper propose aims for intelligent smart phone.

As smart phone became popular, a word smart phone syndrome is also commonly used among us. Its excessive uses cause adverse effects on daily lives such as mental and physical health education and individual relationships. This paper targeted to undergraduate students who are mostly using smart phones to analyze on their perception of smart phone syndrome and a reality of typical syndrome such as digital forgetfulness, smart phone addiction and dependence on Kakaotalk. It also suggested basic countermeasures for preventing smart phone syndrome. The perception on smart phone syndrome of undergraduate students using over the average 5 hours a day was resulted to be very low, and it is analyzed smart phone syndrome including digital forgetfulness, smart phone addiction and dependence on Kakaotalk is quite serious, so that proper countermeasures and the actions are required.
