We design an integrated production management system that incorporates management tasks of procurement of materials, production, and marketing. It includes MRP simulation on small or medium sized companies, design of databases, and definition of relevant objects in production environments. The system has been designed using object-oriented programming concept not only to represent the real-world situation easily, but also to help system integration. Graphics-User Interface(GUI) is also employed for the efficiency of production planning.

As human-centered design has become new paradigm in the whole field of design, they make an effort to understand users in the field of graphic interface design. However, there are not much of study to systematic process for human-centered approach in graphic interface design. Therefore, in this paper, the study was conducted to develop application methodology of prototype in the graphic user interface design process. The study consists of three sections. first, definition, types and application methods are introduced by secondary research. Second, all the knowledge gathered above by secondary research are integrated in the newly proposed Prototype-based interface design process. There are many types of prototype from idea sketches on the paper to final working prototype realized by computer. It is needed to develop and test appropriate prototype with appropriate techniques by objectives of the stages. Finally, the proposed prototype-base design process is verified and exemplified through the process of using prototype in the development of multi-user educational multimedia product.

This paper discusses the development and use of an integrated system for the design of steel box girder bridges. The system includes pre/post processors designed particularly for the ease of use by adopting GUI(Graphical User Interface). They offer convenient facilities for the management of design data and thus enable the user to draw satisfactory structural designs. In particular, ease of redesign iterations makes better structures possible in this system

Nowadays, the advancement of digital information technology resulting in the increased interest of the management and the use of information has given stimulus to the research on the use and management of information. In this paper, we propose an integrated data mining model that can provide the necessary information and interface to users of scientific information portal service according to their respective classification groups. The integrated model classifies users from log files automatically collected by the web server based on users' behavioral patterns. By classifying the existing users of the web site, which provides information service, and analyzing their patterns, we proposed a web site utilization methodology that provides dynamic interface and user oriented site operating policy. In addition, we believe that our research can provide continuous web site user support, as well as provide information service according to user classification groups.

A long-term water quality study has been initiated by the Korean Ministry of Environment(MOE) - The G-7 Project--in cooperation with two national research institutes, an University research tn and a consulting firm. This study includes the development of computer software for total water quality management system, so called ISWQM (Integrated System of Water Quality Management). ISWQM includes four major components: a GIS database; two artificial intelligence (AI) based expert systems to estimate pollutant loadings and to provide cost-effective wastewater treatment system for small and medium size urban areas; and computer programs to integrate the database and expert systems. ISWQM is to provide user-friendly Decision Support System (DSS) for water quality planners. A GIS was used to create spatial database which stores all the necessary data to n DSS. GIS was also used to integrate the four components of ISWQM from data creation to decision making through Graphic User Interface (GUI). The results from the first phase of this study showed that GIS would provide an effective tool to build DSS using expert system.

In this paper we introduce a software package, the Very long baseline interferometry Network SIMulator (VNSIM), which provides an integrated platform assisting radio astronomers to design Very Long Baseline Interferometry (VLBI) experiments and evaluate the network performance, with a user-friendly interface. Though VNSIM is primarily motivated by the East Asia VLBI Network, it can also be used for other VLBI networks and generic interferometers. The software package not only integrates the functionality of plotting (u, v) coverage, scheduling the observation, and displaying the dirty and CLEAN images, but also adds new features including sensitivity calculations for a given VLBI network. VNSIM provides flexible interactions on both command line and graphical user interface and offers friendly support for log reports and database management. Multi-processing acceleration is also supported, enabling users to handle large survey data. To facilitate future developments and updates, all simulation functions are encapsulated in separate Python modules, allowing independent invoking and testing. In order to verify the performance of VNSIM, we performed simulations and compared the results with other simulation tools, showing good agreement.

ATM networks are widely deployed as the network that is capable of supporting multimedia services efficiently now. To date, a large portion of ATM connections, particularly in the WAN environment, have been of a permanent virtual circuits-requiring management intervention for set-up and tear-down. However, switched virtual circuits are required to support a range of desired characteristics on demand, to a reachable end user. To establish, maintain and release on-demand call/connections, the user-network interface(UNI) and node-node interface(NNI) signalling capabilities are required. Two protocols have been specified for NNI signalling within a public network: the broadband integrated-services user part(B-ISUP) protocol specified by the ITU-T, and the private network-network interface(PNNI) protocol specified by the ATM Forum. PNNI offers different type of internetwork or internodal interface from the traditional B-ISUP approach favored to date public network operators. In spite of its name, PNNI may find its place in network service provide networks as well as in private networks. Thus many public network operators and ATM equipment manufacturers are still unable to choose the NNI interface architecture of their system. In this paper, we survey the characteristics of the B-ISUP and PNNI protocols, and investigate the applicability issue of these specifications to the ATM-based Information Infra-Network of Korea. Analyzing the characteristics of the two protocols and clarifying the NNi requirements of the ATM-based Information Infra-Network of Korea, we propose that the B-ISUP protocol is more suitable than PNNI.

This paper describes the architecture and development of real-time monitoring system for ILRT (Integrated Leakage Rate Test). Object Oriented approach is used during the analysis and design. The architecture can be spited into two modules. First one is the Interface module, which, takes care of the communication between the server and the clients, and the second module is the Graphical User Interface (GUI) module, which takes care of the GUI in the web browser of the client. The technologies used includes Java, Java Bean and Java Applet. Etc.
