The effect of smartphone usage motivation on application display advertising attitude and advertising avoidance was investigated. In addition, the mediating effect of advertising intrusion was confirmed. The total number of participants in the study was 309, and the data collection method used a survey method. Covariate structural analysis was conducted to investigate the causal relationship between smartphone usage motivation and advertising attitude and the mediating effect of perceived intrusion on advertising avoidance. There are five results. First, the motivation for using smartphones had a significant effect on the display advertising attitude of smartphone applications. Second, the display advertising attitude of the smartphone application had a significant effect on the advertising avoidance behavior. Third, the display advertising attitude of smart phone application had a significant effect on perceived advertising intrusion. Fourth, the perception of intrusiveness of display advertising in smartphone applications had a significant effect on advertising avoidance behavior. Finally, it was confirmed that the perceived ad intrusion has a partial mediating effect in the causal relationship of the smartphone application display advertising attitude to the ad avoidance behavior. The results of this study will contribute to suggesting strategies to reduce advertising avoidance behavior.

Smart phone and its applications are currently bringing about significant changes in our lives and it is expected that applying such technology in the area of agriculture could increase the value added and productivity of agriculture with its various uses. This paper proposed a smartphone-based application for monitoring and managing livestock barn in real-time anytime, anywhere. In the proposed application, the livestock barn environment and video information collected in ubiquitous livestock barn based on wireless sensor networks can be used by user to monitor the livestock barn in real-time through the use of smart phone to control the livestock barn facilities anytime, anywhere. This application can provide user convenience and increase productivity by allowing users to control their livestock barn facilities.

스마트폰이 도입된지 불과 몇 년만에 모바일 컴퓨팅은 이제 생활과 밀접한 다양한 콘텐츠를 소비하고 공유할 수 있는 공간이자 도구가 되었다. 이제 우리의 일상은 스마트 폰의 어플리케이션이나 SNS 등을 이용해 보다 합리적인 정보 탐색을 위하여 얻고자 하는 정보를 검색하고 실시간으로 공유한다. 최근 선호하는 스마트폰 어플리케이션은 오락, 유틸리티, 소셜 네트워크의 비중이 크다. 본 논문에서는 이러한 스마트 폰의 흐름에 발 맞춰, Android기반 게임 애플리케이션을 구현하고자 한다. 본 애플리케이션은 컴퓨터에서만 즐길 수 있던 게임에서 벗어나 보다 접근성이 편리한 스마트폰에서 실행할 수 있을 뿐 아니라 커뮤니케이션 인프라(별점 주기, 랭킹)와 item shop 기능을 제공한다. 본 연구에서는 더블버퍼링, 각종 센서, Surface View 등을 활용하여 스마트폰 게임 애플리케이션을 제작한다.

Nowadays, smart devices are the target of the digital forensic investigation. Among various smart devices, we can obtain much information from smart phone which is provided with continuous power and used for data communication. This paper deals with the traces to be left in Android smart phones after using the navigation applications with the GPS function. We selected navigation applications(domestic and overseas) which have a high number of download times, anaylzed them and discussed the meaning of the analysis result in digital forensic investigation.

Recently, development of app for smartphone is much and many apps provide information by reproduced with achieved information from internet site. There is a need of method dependent on reproduced data by app. For solving these requirements, this paper first identifies problems such as lower hardware performance and limited bandwidth when legacy web pages are accessed by smart phones. This paper suggests three methods, "real time," "cache," and "static" to develop application programs for smart phones by considering identified problems.

With probably too many smart phone applications downloaded, it is sometimes frustrating to find frequently used applications quickly. In this paper, we propose a learning application that learns what applications a user frequently uses and match them with several signals that user designated. This learning applications uses ART2 algorithm that is good for stable real-time learning. By executing this learning application, a user simply chooses an application that is to be quickly searched and then draw a figure that would match the designated application at the upper left corner of our learning application. The proposed learning application transforms the background with 0's and the figure with 1's and normalize them to be used as inputs for ART2 and ART2 does clustering to setup a match table between applications and figures. After learning, a user simply draws a figure to execute one's frequently used application.

스마트폰 어플리케이션 오픈마켓은 누구나 자유롭게 어플리케이션을 개발하여 등록하고, 사용자가 원하는 어플리케이션을 구매하여 사용할 수 있다. 이러한 시스템은 어플리케이션 시장을 활성화시킨 반면 많은 보안상의 위협을 야기한다. 이러한 문제점을 해결하기 위해 여러 방안이 제시되고 있는데, 본 논문에서는 어플리케이션을 등록할 때의 검증절차를 보다 효율적으로 개선하기 위한 보안등급 세분화를 연구하였다. 개발자가 어플리케이션을 마켓에 등록 시 적절한 검증 등급을 설정하여 검증시스템의 효율을 높이고, 마켓에서 등록된 어플리케이션에 검증된 보안 등급 정보를 제공함으로써 사용자에게 구매할 어플리케이션의 안정성을 판단할 근거를 제공해 준다.
