In recent years, medical procedures have become more complex, while financial pressures for shortened hospital stays and increased efficiency in patient care have increased. As a result, several shortcomings of present film-based systems for managing medical images have become apparent. Maintaining film space is labor intensive and consumes valuable space. Because only single copies of radiological examinations exist, they are prone to being lost or misplaced, thereby consuming additional valuable time and expense. In this paper, mini-PACS for image archiving, transmission, and viewing offers a solution to these problems. Proposed mini-PACS consists of mainly four parts such as web module, client-server module, internal module, acquisition module. In addition, mini-PACS system includes DICOM converter that non-DICOM file format converts standard file format. In client-server module case, proposed system is combined both SCU (service class user: client) part and SCP(service class provider: sewer)part therefore this system provides the high resolution image processing techniques based on windows platform. Because general PACS system is too expensive for medium and small hospitals to install and operate the full-PACS. Also, we constructed web module for database connection through the WWW.

In this study, a web-based system was developed by utilizing finite element method and virtual system designed using Virtual Reality Modeling Language (VRML). The simulation program for axi-symetric sheet forming is developed using finite flement method. The developed system consists of two modules, client module and server module. The client module was developed by using Active-X control. The input data for FEM calculation is transferred to the server module by using communication protocol. Then sever module performs several successive processes: input data generation, forming simulation, conversion of results to VRML format. After that, the results from the simulation can be visualized on the web browser in client computer. Besides, client module offers the capability to control and navigate on virtual forming machine and calculated result. By using this system simulation result can be investigated more realistically in virtual environment including forming machine.

We propose the PBSM(Protocol-Based Security Module) system which guarantees the secure data transmission under web environments. There are two modules in the PBSM architecture. One is Web Server Security Module(WSSM) which is working on a web server, the other is the Winsock Client Security Module(WSCSM) which is working on a client. The WSCSM security module decrypts the encrypted HTML document that is received from the security web server. The decrypted HTML document is displayed on the screen of a client. The WSSM module contains the encryption function for HTML file and the decryption function for CGI(Common Gateway Interface). The formal analysis methodology is imported from format theory for analyzing the data flow of the PBSM system. The formal analysis methodology is based on the order theory.

Geographical Information System (GIS) is composed of hardware, software, data, and methods. Among the components, data is considered to be the most important factor in GIS. In this paper, we describes HVF, the most recent technology pioneered by GIS researchers. HVF is a format for efficient usage of spatial object in order to express, save and transform in Internet GIS. Fist, we describe the definition of HVF syntax, then the implementation of Header Section Generation Module and Main Section Generation Module through the API. Second, we develop a spatial object converter for HVF to transform figures into data structures, which are compatible among different GIS applications. For this purpose, we design and implement three units of modules, which are File Manipulation, HVF Import and HVF Export Module. Since the issues of network traffic and Hangul processing in Internet GIS are important, we expecially consider development of HVF in terms of spatial data size.

A steam explosion module, STX, has been developed using the mechanistic steam explosion analysis code, TEXAS-V, in order to estimate the dynamic load with steam explosion by implementing the module to the integrated safety analysis code, MELCOR. One of the difficulties in using mechanistic steam explosion codes is that they do not have any obvious criteria for defining some uncertain parameters such as triggering timing, triggering magnitude, mesh axial length and mesh cross-sectional area. These parameters have been user decision parts in the past. Steam explosion sample calculations and sensitivity studies on uncertain parameters were conducted to investigate those uncertain parameters. The TEXAS-V simulations were summarized in the format of a look-up table and a linear interpolation technique was adopted to calculate the steam explosion load between the data points in the table. The STX-module merged with MELCOR showed the same results as the original MELCOR and additionally it could estimate the steam explosion load in the reactor cavity.

This paper refers and implements XML Web services, which supports networked interchanges of moving object information. XML Web services are expected to be fundamental building blocks in the move to distributed computing on the Internet. As an interchange format, GML encodes semantics, syntax, and schema of geospatial and geoprocessing-related information resources. It can give great benefits to utilize raw data easily as an XML encoding format does. This paper proposes a full coverage of interoperable location trajectory services consisting of 3 independent modules: a moving object database, a data processing server, and a web services interface module. For communications, SOAP protocols and WSDL documents are used, which can guarantee an interoperability of a system regardless of different platforms and service channels. This paper also designs a GML data format that represents location information of probe cars.

In this paper, a independent and structured microassembler was designed for easily changing the system design, and for designing various microarchitecture. When the designer's hardware and microprogramming process were made concurrently, it is needed to easily change or improve the instruction set and executable code format. But this type of developed environment requires a high const and a large software system. A proposed microassembler was designed so the designer directly defines the microinstruction set and format to be executed. And we implemented a module from each part of the software, so it is now possible to use practically and upgrade the function of each part, First, the symbol was separated from the assembler. And then microinstruction was copied into it. The microinstruction format was designed using the defined language that was designed for free microinstruction. This was implemented in an IBM-PC by using the C-language, FLEX,and BISON.

AS EC is expanded and activated, many message standards, EDI, XML, UDF, etc are defined and is used at various business part. But the existed translator supports only one mapping translation, for example, EDI-to-UDF, UDF-to-EDI. So many user must be introduced a new translation when new business(message standard) is beginning, To solve this problem, we propose XConverter System as registering mapping information which is able to transform to user requested format using same translator even though it is transferred any formatted message in this paper. Also, We design and implement this system which is capable to integrate with existed legacy system, including DB transformation functionality. The .XConverter System supports changing the business message format to the common user used message format. And this system easily migrates with existed legacy system because DB transform module is component. Therefore, The proposed System is more various and flexible than the other translation system that provide just one mapping transformation.

GIS can only be applied to certain areas by storing format. It is subordinate to a system when displaying geographic information data. It is therefore inevitable for GIS to use GML that supports efficient usage of various geographic information data and interoperability for integration and sharing. The paper constructs VisualGML that translates currently-used geographic information such as DXF (Drawing Exchange Format), DWG (DraWinG), or SHP (Shapefile) into GML format for visualization. VisualGML constructs an integrated map pre-process module, which filters geographic information data according to its tag and properties, to provide the flexibility of a mobile device. VisualGML also provides two major GIS services for the user and administrator. It can enable visualizing location search. This is applied with a 3-Layer POI structure for the user. It has trace monitoring visualization through moving information of mobile devices for the administrator.
