2014년 가트너에서 조사된 통계 자료에 의하면 스마트폰 사용자 4명중 3명은 안드로이드인 것으로 나타났다. 즉, 안드로이드에서 취약점이 발생할 경우 다른 스마트폰 OS에서 취약점이 발생할 때보다 3배 이상의 피해가 예상된다고 할 수 있다. 따라서 안드로이드 환경에서 앱에 대한 취약점을 찾고 조치를 취해야하는 작업이 지속되어야 한다. 그러나 취약점을 찾고 조치를 취하기 위해 분석가는 많은 시간을 소모하는데 비해 앱의 증가 속도는 매우 빨라 취약점 점검을 위한 자동화 도구는 필수적일 수밖에 없다. 이에 본 연구는 안드로이드 환경에서 작동하는 앱을 대상으로 취약점 점검을 수행하는 도구를 개발하고 연구하였다.

최근 스마트폰이 빠르게 보급되면서 모바일 OS 시장에서 안드로이드는 79%의 시장점유율을 보여주고 있다. 이와 같은 안드로이드의 빠른 성장과 마켓 시장의 확대에 따라 수많은 애플리케이션이 개발되고 있다. 하지만 개발자 등록과 애플리케이션 배포 절차가 비교적 간단하기 때문에 충분한 검증절차를 거치지 않은 애플리케이션이 얼마든지 배포될 수 있다. 따라서 안드로이드 애플리케이션 개발단계에서 충분한 테스트 작업이 필요하다. 이에 본 논문에서는 단위테스트와 통합테스트를 통해 안드로이드 애플리케이션의 완성도를 높이기 위한 테스트 자동화 시스템을 설계하였다.

Since 2009 the number of users of smart phones and tablet PC is growing exponentially. In particular Apple's iOS and Google's Android OS are the heart of this remarkable growth, most of smart phone and tablet PC are designed to operate based on these two OS. Such increasing use of smart devices has led to changes in the social environment that allows, without the constraints of time and place. However, such development does not supply only ease to do something, even compared to past, financial fraud and information leakage are easier than before by variety of new types of attack for example phishing, pharming, smishing and qshing. So according to this paper, analyzes for smishing attack, propose a countermeasure system of the technical way and proved its higher performance compare to the existing method.

Embedded System operates hardware installed like processor, memory device, various input/output devices and software to control them. This thesis presents MPU module and Base board which are efficient industrial control through design and manufacture as developing S5PV210 CPU of SAMSUNG used by ARM Cortex-A8 based on Android which is Open mobile platform is installed to embedded system. Data for temperature and humidity which are received by CAN communication module proved the suitability and validity for the embedded platform design as implementing application program employed the native App with Linux Kernel based on the Android OS and application of HTML5.

The growth speed of the industry of national smart phone game service has become faster and the its economical and cultural effect has increased steadily these days. The DB design for data perpetuation in C/S MMO which has accumulated data a lot and many simultaneous plays like smart phone games is very important. This paper, mindful of the operation and the scalability suitable for android OS, by utilizing RDBMS, enabling very short, many transactions, their complexity, and a large amount of game data process, suggests fully-qualified MMORPG game DB design techniques widely availabe for more than online game industries.

This paper is the study of effective recovery system in the android set-top box, using NTP (Network Time Protocol). Because of Response to the user react quickly in case of a set-top box, needs compared to other electronic products, set-top box is one of always powered features to work at home. But general-purpose OS such as Android-based set-top box have to reset for cache & main memory initialization. In this paper, we introduce system reset & recovery by NTP client utilizing.

Nowadays, it is animately studied on IoT(Internet of Things) on the strength of development of the short-range communications technology and smart device. In this paper, it made a interface board which is capable of short-range communications networks based on embedded linux and Android OS (operating system). and we also made a IoT sensor module and device driver module. This devices are easily separated and changed and also simply embodied in IoT, and It was implemented using the Android app that allows you to control the sensors.

These days, smart phones are being widely used and accordingly, a larger number of consumers have become interested in them, thus many applications are being developed with a variety of forms. There are various fields in it, such as multimedia, games, information and education, as per users' disposition and characteristics. As for the current contents for language education in mobile environment, the market is dominated by contents for learning foreign language such as English, Japanese and Chinese, while contents for educating Korean language are minuscule. In this paper, thus, we design and implement a elementary Korean language educational contents for foreign beginners who can use the contents at their smart phones with Android OS.

To activate the use of the mobile Internet, its service must be changed itself, as well as improvement of its use environment, and the changing direction must orient 'SMART SERVICE', which it provides in the fastest, easiest, most comfortable way by selecting the core information users want most. This paper suggests that the users of smartphones access diverse contents out of the mobile apps anytime and anywhere and use them conveniently, by activating social communication among the users of school information through the mobile app development suitable for Android OS.
