To integration the field device as a control system correctly in fielders systems. We have to offer the DD(Device Description) with the function and internal parameter into the configuration software. The DD which is written in the DDL(Device Description Lansuage) is made as IEC 61804-PART 2 and it is used in Profibus, Foundation Field bus, HART. However, the DD is dependent to the fieldbus and it doesn't have a suitable form in the industrial Ethernet. Therefore, in this paper, we described the internal function and parameter of the Field device as XDD(XML for Device Description) by using XML (extensible Markup Language) which isn't dependent to fieldbus and has a suitable form for industrial ethernet. Futhermore, we present the possibility of XDD's application in the distributed control system by examining the possibility of ethernet's development in the industrial area.

Recently, the demand for various contents and mobile web service has been rising due to the improvement of the techniques of wireless networks. In mobile web service, it is essential to exchange the device informations and contents using specific information which are standardized for users, operators and contents providers. This is based on the existing service providers based on the existing terminal, which provides information to help plan and operate independently of the mobile Web services and content services for various users needs. In this paper, the interoperable DDL is proposed for providing contents to fit with each different mobile device, which contributes toward the optimized mobile web service and guarantee the interoperability of device information. and we implemented the device information processing system, which has the purpose of servicing the device information and verifying the result to the interoperability of mobile web service on proposed DDL and the description language of the device information.

Device Description that is described as C-based DDL(Device Description Language) should be provided for the control system to use the progressive function of field device in the distributed control system. DD expresses field device function itself and parameter. DD is used to set a necessary function far a control strategy in the central control system. DD technology which was adopted as international standard IEC 61804-Part 2 is being used in PROFIBUS, Foundation Fieldbus and HART. However, the DD is dependent to the fieldbus and it doesn't have a suitable form in the industrial Ethernet. This paper presents the possibility of a change from EDD(Electronic Device Description) and GSD(General Slave Data) used for integrating field devices to XDD(XML for Device Description) and verifies it's effectiveness. Also, this paper presents research assignment on the XML application in the distributional system from now on by examining the possibility of Ethernet`s development in the industrial area.

The demand against the contents service which is various with improvement capability of the mobile device. But the capability of heterogeneous mobile device to display contents has a difference from the side of the hardware, software, network conditions so the adaptation of contents is a solution to overcome this difference. This adaptation of contents is based on profile(DDL : Device Description Language) but there is no system which manages the profile efficiently. In this paper, we designed independent DDR(Device Description Repository) system that offers storage and optimized profiles processed by searching and recombination with request conditions.

Due to the improvement of mobile device capabilities, a demand for various contents service is increasing. But the differences from heterogeneous mobile devices force to develop contents which is dependent on a mobile. To solve this problem, adaptation course that reorganize contents by the device capability is needed. In this course, device description is described using device description language but there are some problems that is absence of device description repository and the way to get device description data. In this paper, I suggest device description acquisition module and define the interfaces to access device description repository that I designed and implemented.

Recently, improved capabilities of the mobile device is represented in a demand for same level services with the desktop device services but the service that is developed for desktop device is not compatible with mobile devices. To fulfill these demands, it is needed to provide services with considering features of mobile devices. This means that CP(Contents Provider) must do contents transformation in order to make suitable contents on mobile device. For managing some information that is required to do contents transformation, we need the DDR(Device Description Repository) which can store and search a variety of device information to grasp the constraints on the mobile device as compared with desktop devices. Also, defining standard API is required to offer a service regardless of platforms. Hereupon W3C(World Wide Web Consortium) introduced DDR Simple API. However that specifies the limited functions of DDR, which is inevitable to be added for more precise search services. In this paper, we expanded DDR Simple API and implemented DDR that supports DDL(Device Description Language) conversion and storing and searching device information.

Mobile device will be able to use the various contents from the advancement of the wireless Internet and mobile device manufacture technique. Each devices HTTP headers about under using provides terminal information to contents provider which is provided the contents which is suitable in device. But there is not a standard for a terminal information proηsion and when using the contents of service network outside, interoperability problems mobile communication it will provides terminal information in different method. International Organization for Standard OMA UAProf about under using it solved interoperability problems from outside. But about under using it provides terminal information, MMS support and Smart Card support, against an external storage space supporting information it is not seen clearly UAProf not to be, it will not be able to provide terminal information which is complete. This paper hereupon it designed UAProf in base which provides the contents which has become optimize to the mobile device of domestic environment the mobile device description language which expresses device information which is necessary.

HDL(Hardware Description Language) is the most important modem tools used to describe hardware, and becomes important as we move to higher levels of abstraction. The HDL has been made brisk use of in analog design, MEMS device[1-2], process related field as well as digital design. The most important characteristics of HDL is Abstraction which is the strongest tool that extend greatly designer's design ability. In this paper by the Modelling Continuum with hierarchical structure of abstraction, we apply UML(Unified Modeling Language) to SoC Design with HDL UML makes an easy and visual description of the various levels of abstraction, and gives designers good flexible modeling capabilty for SoC Design.

There are growing demands for improving the patient safety and the effectiveness of medical services through device connectivity and interoperability. However, integration through networking might greatly increase the complexity of the system if it is not properly designed, jeopardizing patient safety. In this paper, we codify safe medical device interaction patterns, and exploit them for the low complexity design and safety analysis of networked supervisory medical systems. We implement the proposed approach as a plug-in of Architecture Analysis and Description Language (AADL). Our implementation enables the modeling and safety analysis of medical devices and their interactions before actual development.
