The existing building control and automation systems which have been applied to buildings are provided by many different vendors and each vendor has its own proprietary protocol. There are many problems in system integration since those building control and automation systems belong to each vendor. Also, the problems of cost and space increase, due to the usage of personal computers as the control servers of DDC(Direct Digital Control) in each facility. Those problems mentioned above can be effectively resolved by using XML Web Services and Embedded Web Server. Embedded Web Server and XML Web Services are technologies emerging out of the IT industries and there are many researches to apply them into many fields. In this paper, Embedded Web Server and XML Web Services are proposed to be used in building control and automation system to resolve problems in building system integration.

To interactively share High Definition (HD)-quality visualization over emerging ultra-high-speed network infrastructure, several lossless and low-delay real-time media (i.e., uncompressed HD video and audio) transport systems are being designed and prototyped. However, most of them still rely on expensive hardware components. As an effort to reduce the building cost of system, in this paper, we propose the integration of both transmitter and receiver machines into a single bi-directional transport system. After detailed bottleneck analysis and subsequent refinements of embedded software components, the proposed integration can provide Real-time Transport Protocol (RTP)-based bi-directional transport of uncompressed HD video and audio from a single machine. We also explain how to interface the Gbps-bandwidth display output of uncompressed HD media system to the networked tiled display of 10240 $\times$ 3200 super-high-resolution. Finally, to verify the feasibility of proposed integration, several prototype systems are built and evaluated by operating them in several different experiment scenarios.

A large portion of the embedded system development process involves the integration of hardware and software. Unfortunately, communication across the hardware/software boundary is tedious and error-prone to create. This paper presents an automatic hardware/software interface generation system. As the front-end of hardware/software co-design frameworks, a system designer defines XML specifications for hardware functions. Our system generates hardware/software interfaces including Device Driver, Driver API, and Device Controller from these specifications. Embedded software designers can easily use hardware just like system libraries. Our system reduces the mistakes and errors that can be occurred when a software programmer directly connects software to hardware, and supports balancing labors between hardware developers and software programmers. Moreover, this system can be used as the back-end for a hardware/software co-design framework.

An intelligent system embedded with multiple sources of knowledge may provide more robust intelligence with highly ill structured problems than the system with a single source of knowledge. This paper proposes th hybrid knowledge integration mechanism that yields the cooperated knowledge by integrating expert, user, and machine knowledge within the fuzzy logic-driven framework, and then refines it with a genetic algorithm (GA) to enhance the reasoning performance. The proposed knowledge integration mechanism is applied for the prediction of Korea stock price index (KOSPI). Empirical results show that the proposed mechanism can make an intelligent system with the more adaptable and robust intelligence.

A methodology for reliability and economic analysis of wind embedded electric power system is presented in this paper. This is done by evaluating the reliability index, loss of load expectation (LOLE), for the power system with and without integration of wind system in the overall electric power system. Economic analysis of the wind energy embedded electric system is done in terms of conventional fuel saving assessment due to the use of wind power generation units.

For the rapid development of embedded software, a variety of development tools have been developed. But, the embedded software developers do not use the available tools fluently and do not improve software productivity as expect because there are short of supporting utilization convenience of development tools. In this paper, we suggest a tool of building custom development environment for improving the utilization convenience of embedded software development tools. The custom development environment helps developers to rapid selection and access of appropriate tools required to develop the embedded software on the specific embedded system. In addition, it enables developers to handle the outputs from development tools associatively. Moreover it is very flexible in extension and integration because it's implementation based on Eclipse technology. We also perform the evaluation of our tool and successfully validate the utilization convenience of embedded development tools. Therefore, we expect that this tool enables developers to use the embedded development tools efficiently, and then it help improving embedded software productivity.

In the fourth industrial revolution era, various commercial smart platforms for smart system implementation are being developed and serviced. However, since most of the smart platforms have been developed for general purposes, they are difficult to apply / utilize because they cannot satisfy the requirements of real-time data management, data visualization and data storage of smart factory system. In this paper, we implemented an open source based smart manufacturing big data platform that can manage highly efficient / reliable data integration for the diagnosis diagnostic system of manufacturing robots.

최근에 임베디드 시스템 개발자들을 위한 프로토타이핑 시스템 도구가 시장에 많이 출시되고 있다. 일찍부터 임베디드 시스템 설계에서 사용자의 요구사항을 분석하고 사용자 편의 인터페이스를 만드는데 있어서 프로토타입은 중요한 요소이다. 프로토타이핑 도구는 다음과 같이 Physical Prototyping (PP), Virtual Prototyping (VP), Modeling Prototyping (MP) 3가지로 나눌 수 있다. 이러한 프로토타이핑 기술을 통합하면 개발에 소모되는 비용내지 시간이 절약되므로써 시장진입시점이 빨라지고 제품의 경쟁력이 향상된다. 하지만 이러한 프로토타이핑을 통합하는데 있어서 여러가지 문제점이 존재한다. 본 논문에서는 여러 프로토타이핑 도구를 통합하는데 있어서 Javabean, ActiveX등과 같이 유연하고 재사용성이 용의한 컴포넌트를 이용하여 문제점을 해결하는 모습을 보여준다. 이러한 기술은 여러 임베디드 시스템을 개발시 재사용성과 유연성을 통한 편리성을 가질 수 있다.
