Recently, the smart devices has been possessed by a large majority of the adult, and offered various personalization services. This paper proposed the lightweight Intelligent Image Security System that notice the existence of any intruder in real time at the place of requiring the security by using smart device. The proposed image security system recognized whether or not intruder exists using the difference frame on the basis of Integral Image and the dynamic background updating algorithms. The intrusion notification is achieved by using the GCM push server that send massages in the application unit of user mobile device, and the SMTP mail server which is use of e-mail standard protocol. In case of the occurrence of intruder, GCM push server send an push-massage by the private mobile device, and SMTP mail server send the intruder's photograph and intrusion time. By the convergence of the various image processing algorithms and the performance of smart device, The proposed image security system can be applied to the various Intelligent Image Security field.

Having information is most important at the present age. Internet is main source of obtaining information and mobile telecommunication let people communicate each other without any time and space limitation. Recently, advanced technology in telecommunication makes two-way service possible. So, the mobile internet service combined internet with mobile telecommunication is widely and rapidly promoted. Therefore user can transmit and receive a lot of information without time and space restriction using various application technologies. This paper deals with machinery that makes human do office work conveniently in vehicle using mobile internet service. Namely, it tries to design mobile internet machinery combining of wireless payment, GPS module, mobile internet, and mobile office etc. And that can transmit and receive e-mail or documents etc. This machinery has various objects, and design process has complexity. To reduce trial error and processing complexity, Axiomatic Design Method is used to design the machinery.

This study investigates the customer satisfaction based on the various levels of many factors such as age, sex, period, motive, preference between wired and mobile service, frequency, and time. Customer satisfaction is measured by 13 dimensions. MANOVA reveals that preference between wired and mobile commerce service, mobile service frequency, mobile e-mail service frequency, wired Internet usage frequency, and mobile Internet usage time have a significant effect on the overall satisfaction. Transmission speed, fare, and ease of operation of mobile Internet service turn out to be improved for better customer satisfaction, the IMT-2000 service in particular.

Through the data communication services in the mobile field in the past of a voice call center (SMS, E-Mail, web surfing, etc.), it has evolved as a "service of smartphone-based" life convenience. According to the latest world book publishing market statistics, the while increasing the proportion of e-books, the proportion of this paper are commercially being reduced. Paper this many e-books in the development of, but active communication in this paper By fusing an NFC-based mobile environment that provides a function to complement the disadvantage of electronic books has, it can give to meet the matters required in more diverse applications. Therefore, in this paper, in order to design and implement an NFC-based mobile phonic fairy book application of, and the efficiency and maintenance of the development through a way to save on rather than storing the information of the management target device server We have implemented a NFC-based mobile education phonic fairy book application that takes into account.

Due to the expansion of non-face-to-face services, the demand for user identification for mobile devices is increasing. Recently, mobile resident registration cards, mobile driver's licenses, etc. are installed in mobile phones and used for user identification and authentication services. In order to identify a user online, unique identification information of the online user is required. In particular, in order to provide information only to online users, it is necessary to accurately deliver information to a mobile device owned by the user. To make this service possible, it was realized with the advent of mobile electronic notice service. However, the identification of online service users and information on mobile devices owned or subscribed by the relevant users require safe management as personal information, and it is also necessary to increase the convenience of online service users. In this paper, we propose an operating standard for providing a mobile electronic notice service that sends electronic notice using a mobile device owned by the user. The mobile electronic notice service is a service that provides notices expressed in electronic information to the recipient's cell phone, mobile app, e-mail, etc. Therefore, as the use of mobile electronic notification service increases and the provision and use of connecting information to identify users increases, it is necessary to expand the mobile electronic notification service while safely protecting users' personal information.

Advances in mobile communication and digital video technology enable to commercialize converged multimedia services such as VoD in the mobile networks. Media convergence is evolving into U-Cloud and mobile IP-TV services constituted by high-speed mobile multimedia networks and integrated personal devices. This paper proposes a resource allocation scheme to guarantee QoS of converged mobile multimedia services, and simultaneously maximize legacy services in heterogeneous wireless networks. Performances are analyzed by the simulation.

장소와 시간에 관계없이 언제든 네트워크에 접속해 컴퓨팅할 수 있는 유비쿼터스 환경은 이제 디지털 기술의 발전으로 전문가 영역에서 생활현장으로 까지 계속 퍼져나가고 있다. 본 논문에서는 언제 어디서나 멀리 떨어진 곳에서도 내 PC를 제어할 수 있는 홈 네트워크 기반의 시스템으로 사용자가 휴대폰을 이용하여 네트워크로 내 PC를 원격으로 제어하는데 초점을 맞춘다. 이는 사용자가 만든 파일(UCC: User Created Contents)을 모바일을 통해 웹으로 전송해줄 수 있는 효과적인 시스템이다. 그리고 사용자들이 자신의 PC에 원하는 파일을 원격으로 이메일 전송하는 기능 중심으로 서버와 클라이언트 간 통신 구조를 소개, 분석한다. 본 논문에서는 위의 결과를 바탕으로 시스템을 구현하고 실험하였다.

협업 환경의 비즈니스 모델은 Web 2.0 과 같은 협업도구의 정보통신 기술의 발달로 효율성 측면에서 더욱 가속화되고 있다. 웹 2.0 기반의 Wiki 시스템은 협업 도구의 대표적인 시스템이다. 협업작업자는 협업 도구로 메신저, 메일, 게시판 등을 사용한다. 하지만 메일은 그룹작업자가 필요로 하는 자료와 정보를 공유하는 비동기적 협업도구로 사용되고 있다. 협업시스템에서 가장 대표적인 통신수단은 전자우편 또는 메신저라고 할 수 있다. 하지만 DokuWiki 는 협업 시스템으로 적합하지만 통신수단을 제공하지 않는다. 그러므로 본 논문에서는 효율적인 협업작업을 위하여 개인 또는 그룹에 전송된 전자메일을 모두 공유할 수 있도록 하기 위해 전자우편 공유 시스템을 제안한다.

In this paper, we have designed and implemented mobile instant messenger which has extensible presence service capability. Most previous work on instant messaging system has some limitation with regard to interoperability and extensibility. To solve these problems, we have employed the presence service architecture of IETF. In order to provide extensible presence capability in the wireless mobile communication, we have employed the presence service attributes which are defined in OMA's IMPS architecture. In particular, we have designed and implemented the presence service libraries for manipulating the presence information in response to user's requirement. finally, we have developed the wireless E-mail service, employing the presence service architecture, to verity the extensibility.
