Recently, a new theoretical and methodological approach for computational science is becoming more and more popular for analyzing and solving scientific problems in various scientific disciplines and applied research. Computational science is a field of study concerned with constructing mathematical models and quantitative analysis techniques and using large computing resources to solve the problems which are difficult to approach in a physical experimentally. In this paper, we present R&D of EDISON open integration platform that allows anyone like professors, researchers, industrial workers, students etc to upload their advanced research result such as simulation SW to use and share based on the cyber infrastructure of supercomputer and network. EDISON platform, which consists of 3 tiers (EDISON application framework, EDISON middleware, and EDISON infra resources) provides Web portal for education and research in 5 areas (CFD, Chemistry, Physics, Structural Dynamics, Computational Design) and user service.

Real-time video communication technology of hybrid Web-based using JavaScript and HTML5 today is on the rise. Therefore, in this paper, we have studied the real-time videoo communication technology using a Web browser that supports HTML5. It has been designed and implemented a system based on HTML5 and JavaScript , allowing for video communication of real-time, such as you would using the HTTP / WebSockets and RTC API through the Web servers in the Web browser between different each other, utilizing a Web browser was. It is available in a usable terminal equipment of a Web browser PC or notebook, smart pad, such as a smart phone, which is available without installation, such as a plug-in register or another.In all environments the network is connected, it is available in all terminals use the Web browser is enabled, which will be utilized in the field of video communication in a restricted environment.

In order to strengthen the protection of information, public institutions have introduced information security governance system. Public institutions recognizes the importance of information security governance system, and have striven to establish information security governance by establishing institutions and making policies.In this paper, in order to investigate ways that will be the basis for the establishment of information security governance in public institutions, we studied the necessity and model of information security governance. Also, by studying the government policies and cases, we proposed the direction of the policy. 키워드 정보보호, 정보보호 거버넌스, 정보보호관리체계
The amount of smart phones has increased exponentially. Due to the periodic release of high-performance smart phones and upgraded operating system, new smart phones become out-dated over 1 or 2 years. In order to solve environmental constraints of these smart phones, virtualization technology using Thin-Client terminal has been developed. However, in the case of Virtual Machine(VM), the applications associated with sensors and a GPS device can not run because they are not included.In this paper, by implementing the device driver for Android running in a virtual machine in the x86-based systems, it is to provide Android virtualization capabilities such as using the latest smart phones in the virtual machine environment. It would like to propose a method that the virtual device driver receives sensors and GPS information from the old Android smart phones(Thin-Client) that actually work and run as if the real device exists.키워드 : 가상 디바이스 드라이버, 가상 머신, 센서, 안드로이드, GPS
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
