Currently, as the Android platform only supports single-user protection, it needs security solution for multi-users. Specially, it has to protect specific applications which have personal and financial information, and be available to support authority management for contents access. Thus, this paper proposes an integrated user authority manger model for the Android platform. It helps application authority which is capable to divide into three statuses: installation, execution, deletion with the help of information technology.

Portable radiation detection devices currently available, there are a lot of functional constraints. In order to solve these drawbacks, research has been done on a portable radiation detection device based on the Android platform. Since the early stages of research, it is possible to measure the radiation, but The accuracy is worse than the product being sold. Portable radiation detection device based on the Android platform, the error occurs when the temperature changes. Temperature compensation algorithm was implemented to improve accuracy by eliminating errors due to temperature changes.

다양한 모바일 디바이스에서는 스피커와 마이크로폰의 자체에서 발생하는 반향(Echo)에 대한 문제점이 제시되어 녹음할 때 생기는 에코를 제거하기 위한 알고리즘 연구의 필요성이 증대되고 있다. 따라서 본 논문은 적응 신호 처리에 기반한 음향 반향 제어 알고리즘을 안드로이드 플랫폼 기반의 JNI를 이용한 설계 방법을 제안한다. 적응 반향 제거 애플리케이션은 일반적인 LMS 적응 필터를 적용하여 사운드에서 반향을 제거하고 FIR 필터를 사용하여 사운드의 웨이브폼에 FIR 필터를 적용한다. 안드로이드 플랫폼 기반의 JNI(Java Native Interface)를 이용한 설계는 기존에 사용되는 소스 코드를 재활용하고 프로그래밍을 쉽게하도록 도와준다.

In this paper, we propose smart emotional lighting control system based on the android platform. The proposed smart emotional lighting control system be configure android platform and sensibility lighting equipment, expansion device, zigbee module. Smart emotional lighting control system based on the android platform is automatic control possible using the illumination sensor, and by selecting the desired lighting partial control can be designed. The experimental results of the proposed smart emotional lighting control sensitivity than conventional lighting control system decreased the power consumption and efficient lighting control was possible. Office acts will be suitable conditions to control the color and brightness, so they can be controlled from the improves concentration and ability to work.

Design patterns can be classified as software reuse technique that might provide effective solutions to specific problems that occur repeatedly in software development. In particular, object-oriented design patterns are incorporated into various software platforms and frameworks to increase software productivity. This paper aims to support general guidelines relating to design patterns for Android-based game programming. The proper use of the design pattern could be effective in not only for software development productivity, but also for post-development software maintenance. This paper provides fundamental procedures and case studies for applying design patterns to game programming on the Android platform. Typical object-oriented design patterns such as MVP, Singleton, Observer, and State have been applied to the development of Android game programs.

Since only one application has monopoly on LCD device of the mobile device in Android platform, the user can not see two screens together displayed by two applications running simultaneously. In this paper, a dual-app has been defined as two mobile applications running on each device of a pair of two mobile devices and DSAP or Dual Screen Android Platform has been implemented. DSAP does remote-execution of the peer application of a dual-app on the peer mobile device when either application of the dual-app starts to run and supports communication of the pair app over the network. This paper describes details of design and implementation of DSAP and shows a sample case utilizing DSAP.
