  • This paper describes procedure to build a generic reliability analysis database structure and failure data during the conceptual design phase. Reliability prediction utilizing such supporting database system enable the designer to quantify the effects of varying design and operational constrains on mechanical component's failure rate. This leads to compare competing alternatives to the reliability improvement efforts.

  • This paper presents an enhanced web-based distributed system with Single Access Object Protocol(SOAP), which uses HTTP as a communication protocol and XML as a data presentation. The suggested system is applied into a Generic Equipment Model (GEM) for exchanging specified messages(SECS-II), which are encoded into XML presentation, between Equipment and Host via the web sorrel. In this paper, the designed system architecture and its soap components are presented.

  • Recently, in organizations many decisions are being made by groups. And the organization is changing a lot so are groups. To help decision making of changing groups, we need more flexible and more adaptive GDSS. Therefore one of the critical success factors of GDSS is flexibility and incremental improvement. Prior research on specifying design requirements of GDSS suggests generic design requirements. But they are too general to be incorporated directly into system design, because of the disparity between real group and ideal group that the researchers studied. Many design strategies that start from the generic design requirements thus have contingency variables that changes as the characteristics of group change. From the viewpoint of developers, these variables implicate the desirability of flexibility. To achieve flexibility we need new methodology of design and implementation. Nowadays, object-oriented analysis and design methodologies have been progressed to the point that many systems are being developed through these methodologies. In this paper, a design is proposed using Object-Oriented Modeling Techniques(OMT). Exploiting object-oriented paradigm results in a highly flexible and easily upgradable design.

  • The chicken has been growing in Korea for more than a thousand years according to the history book and commercially rising for broiler meat only since 1960's. As income increased mainly due to improved economy, it changes the habit of eating especially chicken meat. The structure changes into a coordinated production and marketing system which forced the prevailed small and independent producers to become a contract farmer under the vertically controlled practices. This coordinated structure began in 1970's and evolved continually to occupy around 90 percent of the market in 2010 with some ten (10) private brands being advertising. The industrial organizations have also conducted the generic promotion by a farmer's check-off program. Over the past 20 years, chicken import steadily increased to meet about 25 percent of the domestic market while the export showed negligible growth. As a whole, the structure change and international trade devoted to increased chicken consumption from 2 kg with the independent operation to 11 kg currently under the coordinated system and import. It is predicted that chicken consumption will grow in years to come and the import will also increase in addition to local productions, considering the free trade agreement that has already been in practice with EU and US to open the market eventually from all sources of supply worldwide.

  • This paper describes an implementation of the document class editor based on ODA(Open Document Architecture). For processing, we divided document structure into generic logical structure and generic layout structure as ODA standard. Also this editor could edit document profile. Using the utility which was implemented to investigate the composed document by object. we confirmed the document. And we could verify the ODIF stream data of the document. We designed this editor based on DAP level 2 of international functional standard. This system was implemented in environment of the X window system and the Motif as graphical user interface. This document class editor will be used to create real document having specific document structure.

  • This paper describes the codesign method for IS-95 based CDMA(Code Division Multiple Access). By codesign we mean to design hardware and software simultaneously. Codesign lead to reduction in design time, cost and power consumption. When we partition a system into hardware and software, some modules with longer processing time and larger power consumption are implemented using hardware and the remaining part is implemented using software. In proposed design, we design the synchronous accumulator of CDMA searcher in hardware and the other part in software, The hardware part is designed using VHDL, while software part is designed using GC(Generic C). We simulated and verified the system using COSSAP in SYNOPSYSTM. Experimentation showed the maximum 48.5% speed reduction compared with the design using software only.

  • Peer-to-Peer (P2P) systems with super-peer overlay networks show combined advantages of both hybrid and pure P2P systems. Super-peer is a special peer acting as a server to a cluster of generic peers. Organizing a super-peer network is one of important issues for P2P systems with super-peer networks. Conventional P2P systems are based on two-level hierarchies of peers. One is a layer for generic peers and the other is for super-peers. And it is usual that super-peer networks have forms of random graphs. However, for accommodating a large-scale collection of generic peers, the super-peer network has also to be extended. In this paper, we propose a scheme of hierarchically constructing super-peer networks for large-scale P2P systems. At first, a two-level tree, called a simple super-peer network, is proposed, and then a scheme of generalizing and then extending the simple super-peer network to multi-level super-peer network is presented to construct a large-scale super-peer network. We call it an extended super-peer network. The simple super-peer network has several good features, but due to the fixed number of levels, it may have a scalability problem. Thus, it is extended to k-level tree of a super-peer network, called extended super-peer network. It shows good scalability and easy management of generic peers for large scale P2P system.

  • A user-friendly modeling interface is developed for a process-based total system performance assessment framework (APro) specialized for a generic geological disposal system for high-level radioactive waste. The APro modeling interface is constructed using MATLAB, and the operator splitting scheme is used to combine COMSOL for simulation of multiphysics and PHREEQC for the calculation of geochemical reactions. As APro limits the modeling domain to the generic disposal system, the degree of freedom of the model is low. In contrast, the user-friendliness of the model is improved. Thermal, hydraulic, mechanical and chemical processes considered in the disposal system are modularized, and users can select one of multiple modules: "Default process" and multi "Alternative process". APro mainly consists of an input data part and calculation execution part. The input data are prepared in a single EXCEL file with a given format, and the calculation part is coded using MATLAB. The final results of the calculation are created as an independent COMSOL file for further analysis.
