초등정보영재학생들에게 있어 스마트폰 앱의 개발은 기본적으로 자바와 같은 프로그래밍 언어 뿐만 아니라 기타 복잡한 프로그래밍 환경 등 어느 정도의 프로그래밍에 대한 지식을 요구한다. 본 연구에서는 전혀 프로그래밍에 대한 기초적인 지식이 없거나 앱에 대한 개발 경험이 없어도 쉽게 앱을 개발할 수 있은 MIT대학의 앱인벤터(AppInventor)를 활용하여 초등정보영재학생들의 창의성을 향상시킬 수 있는 앱 개발 교육프로그램을 개발하고자 하였다. 개발한 교육프로그램은 초등 정보영재 학생들의 창의성 및 문제해결력, 계산적 사고력을 동시에 길러 줄 수 있을 것이다.

With the rapid development of major functions in a smartphone, many applications interacting with a smartphone are introduced and mobile applications converged with various related technologies are announced and rapidly disseminated recently. In this paper, we propose the design of a smart mobile application operated with devices like sensors in order to utilize various functions of the smartphone effectively. The mobile application proposed in this paper uses the bluetooth module of the smartphone, composes the wireless ad hoc network with various sensors around us, and collects bionic context information of the user in real time. The smart application designed and implemented in this paper is the sensor based healthy diet application that can fulfill healthy diet program by reflecting the user's sensed bionic context data in real time.

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.

공중장소에서 충전기에 꽂힌 상태로 무방비로 도난의 위협에 방치되어있는 스마트폰들을 아주 쉽게 발견할 수 있다. 잃어버린 스마트폰은 다시 구매하면 되지만 혹시라도 미처 백업하지 못한 자료나 연락처 등의 소중한 정보의 손실로 인해 피해는 클 것이다. 공중장소에서 충전중인 스마트폰을 절도를 목적으로 무단으로 전원에서 분리할 가능성에 대비하여 경고화면을 보여주는 한편, 만일 무단으로 충전기에서 뽑거나 케이블을 절단하면 경보를 울리는 한편, 현재 위치의 위도와 경도를 SMS기능을 사용해 지정한 전화번호로 해당 정보를 전송하는 기능을 안드로이드에 구현하였다. 이를 통해 도난이 되더라도 스마트폰을 잃어버린 위치와 시간을 특정 할 수 있게 도와 줄 수 있기 때문에, 도난이 의심되는 해당 시설 또는 근처의 CCTV영상을 확보하여 범인을 빨리 특정할 수 있게 함으로써 최대한 빠르게 스마트폰을 되찾을 수 있는 확률을 높여주고, 스마트폰에 대한 절도억제 효과도 줄 수 있다.

In Android smartphones, many apps are developed as service apps to run in the background. If the memory is insufficient, Android forcibly terminates not only user apps that have not used the CPU for a long time, but also service apps. However, a service app is automatically re-launched after a short period of time, so that it continuously consumes memory space. This paper analyzes the number of running service apps and their memory usage in users' smartphones. The number of service apps accounts for up to 65% of the total number of running apps, and their memory usage accounts for up to 55% of the total memory. Moreover, we investigate the effect of the number of running service apps on the response time of smartphones and apps. As the number of service apps increases, the launching time of user apps increases to 22 times. The booting time and app installation time significantly increase with the number of service apps.

We can easily acknowledge the facts that the e-market is increasingly and quickly changed by the smart phone user's. This research focuses the e-service quality and relationship between the e-service quality, customer satisfaction and behavioral intention in the AppShopping Mall. Based on the documentary research, the empirical study was followed by the questionnaire. The 313 usable questionnaires were collected by a self-administered survey. The results reveal that the e-service quality determinants are factors including customer service, app design, security, connectivity and user's convenience, and that the e-service quality is directly or indirectly related to customer satisfaction and behavioral intention. The AppShopping mall managers have to try on their best to find out the customer's needs, manage the lists of the e-service quality and develop the app.

Due to Proliferation of Mobile Devices, the Global Mobile Application (App) Market is Set to Continue its Impressive Growth Trajectory. However, like other Digital Contents, Prevalent Piracy of Smartphone Apps has Become One of the Major Obstacles to the Growth of the Newborn App Industry. The Objective of this Study is to Examine and Better Understand the Effects of Factors Which has been Known to Influence PC Software Piracy. A Research Model Explaining the Impact of Various Factors to Smartphone App Piracy Attitude and Intention is Constructed Based on Theories of Ethical Behavior. A Survey of College Students was Conducted to Test the Research Model. Findings Show that PC Software Piracy Habit and Attitude have Significant Effects on Smartphone Piracy Attitude and Intention. Beliefs Concerning Judicial and Performance Risks Due to Piracy have Little Effects on Smartphone App Piracy Attitude.
