U-Healthcare is one of the major applications in ubiquitous sensor network. U-Healthcare has potential to become a critical service for the people who immediately require emergency ambulatory attention. This paper describes about the real time pulse monitoring and reporting system, consisting of two components: thus, the one is a reliable bio-sensor that continuously monitors the pulse information of the subject, and the other is the automatic transfer system that transmits pulse information to both his/her family and hospital care system through the Base Station. In the hospital, this bio-information can be used to treat the patient accordingly. I designed the pulse information monitored by a bio-sensor module that transfers the pulse information to both the Base Station and the central monitoring system through transmitting protocols such as Zigbee and TCP/IP, as well as designed the architecture of information packets for the corresponding protocols. Furthermore, the central monitoring system automatically parses the pulse information of the subject into the web database server, which can continuously provides the real time information and status of the subject via an internet browser to the clients who are family members of the subject and the authenticated medical care personnel as well.

H-Anim is an international standard that Humanoid Animation Working Group in Web3D Consortium defined the data structure necessary for human animation. Various libraries and tools have been generated according to the structure, but they still have restrictions to represent realistic humanoid motions. This paper presents the method of generating realistic human motion using motion capture data in order to define motion for humanoid animation based on H-Anim standard. In order to implement this, we have defined a data structure capable of receiving motion capture data and implemented a motion browser. The human motion data structure defined in this paper is based on X3D and intended to have compatibility through networks and various browsers.

Recently, The range of Internet based information environment is spreading over core business area, as well as simple information provision area. Especially, with spreading WWW technology, markup language based technology is emerging as an important part in Internet based business. But, the data made by SGML can only see by using SGML Browser, so it has some problem in information providing at Internet, and compatibility of data between Data source. So, this study suggests essential architecture and technique for migrating from SGML to XML environment. In our study, we use 600MB SGML data that are selected from 3Tera DataBase of SGML as testing target for migration. We can reduce data displaying time after migration, can do mobile computing which is based on Internet as a result of this study. And the same technique and idea that is used in this study can apply to more large SGML Environment without changing. So, It will be very helpful to the reader who is interesting to migrate from SGML doc to XML doc.

As the number of elderly people living alone has been increasing in the recent years, systems for their safety have been required, and some related services or pilot systems have been operating. These systems provide the monitoring service for the activities of the elderly people living alone with indoor location tracking technology using the various sensors. However, most systems provide services on expensive infrastructure such as attached tags and mobile devices. In this point, this paper attempts to suggest a system based on low cost sensors to collect event data in home environment. And a main characteristic of the system is that people can monitor the results of provided services through web browser in real time and the system can provide related context information to guardians and health care managers through SMS of mobile phone.

This paper proposes a new authentication model to solve the problem of personal information takeover and personal information theft by service providers using centralized servers for user authentication and management of personal information. The centralization issue is resolved by providing user authentication and information storage space through a decentralize platform, blockchain, and ensuring confidentiality of information through user-specific symmetric key encryption. The proposed model was implemented using the public-blockchain Ethereum and the web-based wallet extension MetaMask, and users access the Ethereum main network through the MetaMask on their browser and store their encrypted personal information in the Smart Contract. In the future, users will provide their personal information to the service provider through their Ethereum Account for the use of the new service, which will provide user authentication and personal information without subscription or a new authentication process. Service providers can reduce the costs of storing personal information and separate authentication methods, and prevent problems caused by personal information leakage.

Recently, the interest on object oriented design patterns has been increased considering to reusability of software and efficiency of maintenance expense in designing software architecture. In this paper, we design the paper submission management system applicable to specific domain using domain object interface based on object oriented design patterns, and then implement it with Java and XML. The proposed system applies method of implementation by assemblying each system objects with upward after system entire architecture design by combining properly downward method and upward method and applies with GoF Design pattern. As well as, we convert domain data of system into the form of various persistent objects through XML, and minimize the complexity of system by not adopting method that generates domain object as in Class with automatic. Finally, the implementation of our system can be used in general C/S environment, but we implement system user GUI using the XSLT built in general web browser in consideration for user convenience and consistency.

Manufacturing Message Specification (MMS) is designed as a communication standard protocol, ISO/IEC 9506, on factory automation for messaging between heterogeneous programmable unit controller, PLC, NC, Robot, of different vendors on the networks. MMS is also a standard protocol of OSI reference model application layer, In this paper, we show an implementation of MMS over TCP/IP using ANSI-C programming language on the unix environment, and make java classification using java native interface (NJI) with MMS library. The use of java classification provides a basic environment ot overcome a difficult programming with different MMS application programming interface (MMS-I) which requires a siklled programming technique of graphic user interface (GUI). In this paper, we implement a MMS application program of the automated assembly model for printed circuit board based on WWW which shows the operation, control and monitoring of real manufacturing device (RMD) with web browser providing users for consistent user interface.

Metadata is data about data that is used to mange data itself. As applications based on DBMS are increased, it is suggested that metadata model and metadata interchange model to manage metadata in DBMS. but metadata which is in the form of XML (eXtensible Markup Language) document is generally stored into RDBMS. Therefore In this paper, as for the method to store metadata of RDBMS into OODBMS, we design metadata model, metadata interchange model and implement new repository system. The metadata of RDBMS is translated into in the form of XML Document and integrated into XML Data Server on OODBMS, eXcelon and executes retrieval metadata information about RDBMS by XQL(XML Query Language). So It is possible to searchm edit a metadata. The metadata of XML documents stored in eXcelon is easily made to be printed in web browser by applying a XSL (extensible StyleSheets Language). So we can have a detail information about property of metadata in DBMS.

The campus has been composed of a very variety buildings. However, there is almost no easy way to see information about room number of each floor of the buildings and all buildings. For that reason, in this paper, we have developed a 3D simulation system for the 3D visualization of campus building information. Each building and cross section of floor was modeled in 3D based on the actual drawing. And texture mapping were using real photos. The user interface was divided into frames for menu and 3D viewer. When you select a building name from the menu, 3D viewer shows the selected building by zooming. And menu frame is shown the various information related to the building. Also when you select a room number of each floor, a separate web browser shows the cross section by VRML viewer. Conversely, when you click on the building in the 3D viewer, menu frame is shown the various information related to the building. This system is very useful in that provide realistic building information of campus.
