본 논문에서는 안전주행지원 솔루션인 스마트폰용 차선이탈경보 애플리케이션의 실행 속도 향상 방법을 연구하였다. 이전 연구에서 스마트폰(iPhone 3GS) 기반의 차선이탈경보 어플리케이션을 개발하였는데 입력 영상의 처리 속도가 1.52fps였다. 본 연구에서는 영상 처리 속도를 향상시키기 위한 최적화 작업을 진행하였으며 기존의 차선이탈경보 어플리케이션의 차선인식 속도보다 프레임당 평균 0.4초 정도 단축되어 약 4fps 속도로 성능을 보였다. 향후 추가 연구를 통해 처리 속도를 좀 더 향상시킬 것이다.

The smart phone is globally spreading, since the Apple rolled out the iPhone. Thereafter the smart phone ecosystem is being reorganized and strongly governed by the Apple and Google, the mobile OS providers. And the mobile carriers are pushed out of the ecosystem with the progress of the dump pipe. Even though the South Korea has the strong position as a global leader in ICT industries, it have not properly coped with this new situation and is falling to the follower in the smart phone era. Therefore it should try to take advantage of the current of the times like its component industry who already enjoys the fruit. This paper reveals the new structure of the ecosystem along its value chain with the digital open markets, OS providers, phone manufacturers, and mobile carriers. And it shows the economic spillover effects using the input-output analysis. Consequently, this paper will provide the valuable implications to companies in setting up the efficient strategies and the regulator in promoting the ICT industry.

The release of iPhone by Apple in 2009 has changed the life pattern of an individual tremendously. That is, with the emergence of a smart phone, various services including voice/video call, camera, receiving and sending of e-mail, and web browsing have been realized. However, the broader the scope of the use of a smart phone has become, the greater the need for companies to introduce an MDM solution for protecting important documents has become. However the MDM solution may have a problem in that all data such as contacts, pictures, and memos saved in the smart phone can be accessed unlimitedly. For this reason, there is a risk that unwanted violation of privacy may happen to smart phone users. This paper proposed a plan to protect a personal privacy file of smart phone users, which disables access by others except for related smart phone users by enabling a person in charge of security or an MDM manager in a company to have access only to the file which was allowed by smart phone users to be disclosed and by saving non-disclosed files in a virtual disk.

Since the advent of Apple's iPhone, the smartphone industry has been producing new technologies and concepts at an accelerated pace. The speed of progress in this sector is exponentially increasing in accordance with Moore's Law, and smartphones are rapidly changing various aspects of human life. Especially, object control technologies using smartphones are being utilized in various sectors, including robots, home automation, and smart objects. However, the current smartphone object control technology is limited in terms of multicontrol. This study proposes the combined usage of the Bluetooth and Zigbee Modules for multiple object control using smartphones, and presents the necessary application design properties and the methodology for Zigbee communication. The study is an attempt at a territorial expansion of design, as a proposal of new methods for utilizing smartphones in the age of smart objects.

The advancement of touch user interface technology is mostly due to the debut and success of the new user experience (UX), the iPhone. The introduction of Apple's iPhone especially made possible for the user experience to break away from the traditional input device of the mouse and keyboard. It is advancing from the current 3rd generation touch interface technology into the 4th generation non-touch user interface technology. This paper will present a non-touch interaction technology that allows interaction in a three dimensional setting through 3-D space touch. It will analyze current technologies and future emerging technologies.

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.

일본 NTT도코모는 무선인터넷 서비스 아이모드(i-mode)와 포마(Foma)폰으로 일본 이동통신 시장을 석권했으며, 국내에서도 연말쯤이면 플래시 기능이 도입된 휴대폰이 등장할 것으로 보인다. 이에 따라 모바일콘텐츠 제공업체들의 개발 프로젝트에도 변화가 있을 조짐이다. 최근 휴대폰용 플래시 플레이어 상위 버전을 발표한 한국매크로미디어의 이원진 사장을 만나봤다.
