As digital ecosystem has been rapidly transforming into the mobile based platform, several mobile operating system, which is in charge of user interface with mobile device has been appeared. This research suggest critical factors affecting success and failure of several commercial mobile operating systems from Palm OS appearing in 1996 to main mobile OSs appearing in 2013. For this, we analyse several mobile operating OS cases, elicit factors affecting success and failure of mobile OS, and conduct ID3 based inductive learning analyses based on elicted factors and values in case dataset. Through this, we draw rules in success and failure of mobile OS and suggest strategic implications for the commercial success of mobile OS.

As the mobile device supply is increasing currently, the era of N mobile devices per person has opened. Types of mobile devices and OS are increasing continuously. Samsung and Intel are developing TIZEN, the OS mobilized by UBUNTU of Linux is going to be released as well as the market share of Google's Android and Apple's IOS remains above 90%. However, it is a reality that there are not specific technologies or systems which can share files between different OS. Despite of technologies such as Bluetooth and WiFi Direct, constraints are shown in device compatibility and file formats. In this paper, we have studied how to share files between OS as well as mobile devices, and to share files in a wireless LAN environment of heterogeneous variety. Future research includes the mobile phone integration server system that provides services such as introduction, management, maintenance, and repair in one-touch Mobile Server that spread and building are easy.

Minimalism means abstinence characterized by simplicity, clarity, repetition, and exclusion while skeuomorphism means visual metaphor design characterized by retro, function, and emotion. Mobile platform interface has been developed based on those two aesthetic characteristics and user experience is evaluated using apple iOS6 and iOS7 representing skeuomorphism and minimalism respectively in this paper. Those two aesthetic designs on typography, color, and icon were tested with a sample of 35 undergraduate participants in the repeated measures design and the results showed that participants distinguished two types of aesthetic designs, and evaluated that iOS7 is superior to iOS6 on typography and identity. Comparing the levels of the three variables, aesthetic of typography, and accuracy, aesthetic and consistency of icon design were significantly differentiated and this means that although accuracy of icon design of iOS6 is superior to iOS7, iOS7 is superior in the rest of it. Overall, the participants had a positive evaluation toward iOS7.

Recently, diffusion and proliferation of mobile devices increases, per person n opens for the mobile device era. Mobile devices and OS types of continuously growing trend. More than 80% of market share with Google's Android and Apple's iOS as well as Samsung and Intel is developing TIZEN, Linux and Mobile was the UBUNTU which UBUNTU for Phone, UBUNTU touch, Mozilla 's Firefox OS, Microsoft 's windows mobile and many more OS are ahead of the launch. But different OS can share files between systems or technology is not. Bluetooth or WIFI Direct such technologies are present but can be transferred between compatible devices low, resulting in constraints file types also exist. In this paper, is equipped with a WiFi card in an environment where the Android mobile OS party this model and method for sharing files between different research and can share the file system based on research on.

Thanks to diffusions of mobile devices and advances of network technologies, demands for mobile app have been increased dramatically. It has resulted in mobile app industries as well as mobile app authoring tools are facing a crisis over subordinate to specific OS and platform such as iOS, Android and Apple App Store. Because these particular OS and platforms are obstacles to overcome for supporting interoperability and compatibility. In this study, we have conducted expert interviews and surveys to analyze status of mobile app markets and needs for mobile app user and developer. As a result, mobile app based on HTML5 leads to interconnect various mobile devises without additional efforts. Thereby, mobile app user and developer take a positive view of HTML5. However, mobile app developers tend to have the technical path dependence, they especially in venture and small enterprises need to government support for professional manpower training.

With the diversification of mobile devices, the development of web technologies, and the popularization of the cloud, an internet-centric web OS that is not dependent on devices has become necessary. Chromebooks are mobile devices in the form of convertible laptops featuring a web OS developed by Google. These Web OS mobile devices have advantages of multi-user characteristics of the same device and storage and sharing of data through internet and cloud, but it is easy to collect and analyze evidence from the forensic point of view because of excellent security and easy destruction of evidence not. In this paper, we propose an evidence collection procedure and an analysis method considering the cloud environment by dividing the Chromebook, which is a web OS mobile device popularized in the future, into user and administrator modes.

네이티브 앱은 디바이스에 설치하여 직접 실행하는 타입으로 속도가 빠르고 좋은 성능을 보인다. 그러나 네이티브 앱은 특정 스마트폰 OS에 종속되어 실행되므로 서로 다른 이 기종 OS에서 실행되기 위해서는 추가 개발 비용이 발생한다. 이를 해결하기 위해 모바일 웹의 개발이 증가하고 있지만 모바일 웹의 사용자 인터페이스를 네이티브 앱과 동일하게 구성하기 쉽지 않은 단점이 있다. 본 논문은 이 기종 스마트폰 환경에서 앞서 언급한 문제점을 해결하기 위해 cocos2D를 활용한 모바일 웹 설계 및 구현 결과를 제안한다. 제안된 모바일 웹은 기존 모바일 앱의 사용자 인터페이스와 유사하게 구성하여 이질감을 없애고 OS에 상관없이 동일하게 실행된다. cocos2D 게임엔진을 활용하여 사용자 인터페이스를 설계하였다. 이것을 모바일 웹으로 구성하기 위해 JAVA Script에 내장하여 HTML5로 구현하였다. 구현결과는 현재 사용되고 있는 스마트폰 OS 및 여러 디바이스에서 검증하였으며 높은 가동률을 보였다. 논문에서 제안된 기술을 활용할 경우 개발자는 개발에 소요되는 비용을 줄일 수 있을 것으로 예상되며 사용자의 경우 디바이스의 제약 없이 모바일 어플리케이션을 사용할 수 있을 것이다.
