Recently, we are living in the world of information and ubiquitous technology strayed away from the fixed network systems resulting in an increase of using mobile terminals which is convenient for mobility and functionality. Because the diversification of mobile devices to communicate between disparate mobile terminals is difficult, the two kinds of operating systems and hardware for data communication between the terminals is needed to convert the data. The proposed instant messenger design in MRP-S3C2440A (Windows CE 5.0) and Nexio XP30 (Windows CE .NET 4.1) were tested and applied. Usually the mobile terminal has an information on a central server. Sender terminal receives the message according to the characteristics of the terminal after converting was sent to the receiving terminal. Receiving-side terminal without a separate conversion process, it was the output terminals. This paper deals with the proposal and implementation of designing an instant messenger application program between the two different mobile terminals and network systems.

We studied the technique which can control the real system without additional hardware drivers using virtual machine driver operated on the windows operating system. We showed the feasibility of the proposed scheme under the error and the delay of a sampling time on the multi task processing through the load test of the experiment using graphic user interface.

The Virtual Interface Architecture (VIA) is usually suggested as a new standard high-performance communication of the cluster systems. However the VIA specification aims for platform independence, the current Intel VI Provider Library (VIPL) design favors systems with Intel architecture processors running the Windows operating system (OS). This paper aims for clarifying the guesstion problem of VIA and VIPL in the newtrul time of CPU Architecture and OS further more, It suggests the solution aiming the communication in the other CPU or OS

IT security companies have been releasing file system filter driver security solutions based on the whitelist, which are being used by several enterprises in the relevant industries. However, in February 2019, a whitelist vulnerability was discovered in Microsoft Edge browser, which allows malicious code to be executed unknown to users. If a hacker had inserted a program that executed malicious code into the whitelist, it would have resulted in considerable damage. File system filter driver security solutions based on the whitelist are discretionary access control (DAC) models. Hence, the whitelist is vulnerable because it only considers the target subject to be accessed, without taking into account the access rights of the file target object. In this study, we propose an industrial device security system for Windows to address this vulnerability, which improves the security of the security policy by determining not only the access rights of the subject but also those of the object through the application of the mandatory access control (MAC) policy in the Windows industrial operating system. The access control method does not base the security policy on the whitelist; instead, by investigating the setting of the security policy not only for the subject but also the object, we propose a method that provides improved stability, compared to the conventional whitelist method.

Operating systems and application programs have security vulnerabilities derived from the software development process. Recently, incident cases related with the abuses of these vulnerabilities are increasing and the damages caused by them are becoming very important security issues all over the nations. Patch management is one of the most important processes to fix vulnerabilities of softwares and to ensure a security of systems. Since an institute or a company has distributed hierarchical and heterogeneous systems, it is not easy to update patches promptly. In this paper, we propose patch management framework to safely distribute and install the patches on Windows, Linux, and Solaris client systems. Besides, we considered extensibility and hierarchical structure for our patch management framework to support large scaled network environment.

실시간 운영 체제(Real-Time Operating Systems)는 시스템 동작이 논리적 정확성뿐만 아니라 시간적 정확성에도 좌우되는 운영 체제이다. 그리고 실시간 운영체제는 멀티태스킹(Multitasking) 과 ITC(Inter Task Communication)을 제공한다는 점에서 일반 운영 체제인 Windows, Linux, Unix등과 같지만 시간 결정성을 보장해야 한다는 점에서 일반 운영 체제와 다르다. 이러한 실시간 운영체제에서 프로그래머가 디버그 정보를 알기 위해서 여러 가지 기법을 사용하게 된다. 본 논문은 실시간 운영체제에서 시간 결정성을 지키면서 메모리에 관련된 디버그 이벤트들을 알기 위한 버퍼의 설계 및 구현에 대해 기술한다.

Unity programs are largely recognized as game development tools. However, it has many functions built in, so it can be applied to various fields as well as game development. Therefore, in this paper, we propose a smart farm environmental control program using Unity and Photon. The proposed program has vast compatibility that is not limited to specific devices, and it is very easy to build network systems for remote control. In addition, the proposed programs were installed on various devices such as pc and smartphones, making it easy to control the smart farm environment system. Through experiments, it was confirmed that data transmission and reception between Windows and Android, other operating system environments, and that smart farm systems were operating normally.

Nowadays, mobile devices such as smartphones and tablet PC's are making big changes in our life. The most widely used mobile operating systems are Google's Android, Apple's iOS and Microsoft's Windows Mobile. Among them, Android has been researched in various electronic fields such as smartphones and tablet PC's as well as automobiles, Media oriented systems transport(MOST) is a standard for high-speed multimedia communications in automotive industries. In this paper, we present the design results of in-vehicle infotainment software using MOST network based on Android.

Traditionally, simulation-based learning games which are known as flight-simulators have been constructed as a black-box game. Within a black-box game, game-players can view and modify only a part of model parameters. Game-players cannot change the structure of a simulation model. In a black-box game, game-players cannot understand and learn the system structure which is responsible for the system behavior. In this paper, the multi-tasking at the level of operating systems is exploited to enhance the transparency of simulation-based learning game. The white-box game or transparent-box game allows game-players ot view and modify the model structure. The multi-tasking solution for white-box learning game is implemented with Smalltalk language on MS-/windows operating system.
