Recently, the development paradigm of enterprise information system has been moved from 2-tier environment to 3-tier environment. 3-tier environment makes possible to develop more efficient system in terms of the performance, extension, deployment and maintenance. The ship drawing process management system which manages a long-term drawing process and a great number of designers has to support an accuracy and a real-time of information but it is impossible because it is still served in 2-tier environment and some process of them is not developed yet. In this paper, we implemented the analysis and design of system based on CBD(Component Based Development) for the purpose of hanging the environment from two-dimensional Client/server architecture environment to COM＋ based 3-tier architecture environment. And by completing a development of total system, the productivity and the efficiency of the ship drawing process management system will be improved. And a wide reuse of components makes possible to improve the productivity and efficiency of system.

Many enterprises have introduced workflow to enhance work efficiency and support effective work processes in their various work environments. Recently, Business Process Management(BPM), an extension of workflow, is spotlighted in enterprise software markets Although woklflow plays an important role in Business Process Managements, researches in workflow are mostly concentrated on temporal constraints which finds exact execution sequences for complicated jobs. On that reason, majority of workflow scheduling has concentrated on modeling of various resources which should be handled and the interest for workflow scheduling under constraints related to resources is rather unsatisfactory In this paper we presents the Transformation Template based on Concurrent Transaction Logic(CTR) which is suitable for scheduling workflows with resource allocation constraints, and the logical framework. The Transformation Template consists of a Workflow Transformation Template and a Constraint Transaction Template. Especially the Transformation Template can be conveniently used to logically represent new workflows under the existing resource allocation constraints.

The primary purpose of this research is to develop and test a model that explains the process of how trust in a supplier firm and salesperson through relational commitment influence buyer's positive and desirable behavior. In order to do so, we are empirically to examine how a supplier firm and salesperson trust can reinforce buyer's relational commitment leading to relational citizenship behavior using over 138 buying firms, Through structural equation modeling, we find that trust in a supplier firm and salesperson influence the relational commitment and relational commitment enhance relational citizenship behavior. However, trust in a supplier firm is unrelated to the buying firm's relational citizenship behavior whereas trust in salesperson has direct effect on relational citizenship behavior. Finally, we discuss several theoretical and practical implications, and suggest limitations for the research and future research issue.

Component based design is perceived as a key technology for developing advanced real-time systems in a both cost- and time effective manner. Already today, component based design is seen to increase software productivity, by reducing the amount of effort needed to update and maintain systems, by packaging solutions for re-use, and easing distribution. Nowdays, a thousand and one companies in If(Information Technology) industry such as Sl(System Integration) and software development companies, regardless of scale of their projects, has spent their time and endeavor on developing reusable business logic. The component software is the outcome of software developers effort on overcoming this problem; the component software is the way propositioned for quick and easy implementation of software. In addition, there has been lots of investment on researching and developing the software development methodology and leading If companies has released new standard technologies to help with component development. For instance, COM(Component Object Model) and DCOM(Distribute COM) technology of Microsoft and EJB(Enterprise Java Beans) technology of Sun Microsystems has turned up. Component-Based Development (CBD) has not redeemed its promises of reuse and flexibility. Reuse is inhibited due to problems such as component retrieval, architectural mismatch, and application specificness. Component-based systems are flexible in the sense that components can be replaced and fine-tuned, but only under the assumption that the software architecture remains stable during the system's lifetime. In this paper, It suggest that systems composed of components should be generated from functional and nonfunctional requirements rather than being composed out of existing or newly developed components. about implements and accomplishes the modeling for the Product Control component development by applying CCD(Contract-Collaboration Diagram), one of component development methodology, to MRP(Material Requirement Planning) System

The next-generation war game simulators need a technique that reuses resources disperse on the web, and reorganizes federates on the fly based on the various events in real time. So far, HLA-based federates limit their interoperability to military networks, and in syntax-level. Web services techniques are widely used in enterprise applications and provide many proven practices to extend interoperability between WAN resources in semantic level. Two problems are met in order to utilize web services into war-game simulator : 1) How to achieve semantic-level interoperability between federates disperse on WAN, 2) How to interoperate web-based federates and RTI-based federates. In this paper, we provide solutions to the problems and highlight advantages using web-based federates with an example of ASuW(Anti-Surface Warfare).

In order to provide efficient retrieving results for user query on the web environment, the various searching algorithms have developed and considered user's preference and convenience. However, the searching algorithms are developed on the horizontal and non hierarchical web environment in general and could not apply to the complex hierarchical and functional web environments such like the enterprise network. In this paper, we purpose the multi-agent based web mining system which can provide the efficient mining results to the user on the special web environment. For doing this, we suggest the network model with the hierarchical web environment and model the multi agent based web mining system which has four corporation agents and fourteen process modules. Then, we explain the detailed functions of each agent considered the hierarchical environment according to the module. Especially, we purpose the new merging agent and improved ranking algorithm by using the graph theory.

This study aimed for testing the effects of the empowerment in the circumstances of remote management that managers and employees were in separate countries. For this purpose, researchers collected survey data from 79 local teachers in multinational enterprises on English education and performed Structural Equation Modeling. The hypotheses below are revealed as significant. Firstly, empowerment had a positive effect on job satisfaction, but had a negative effect on job stress. Secondly, empowerment had a positive effect on organizational commitment. Thirdly, job satisfaction had a positive effect on organizational commitment. Fourthly, job stress had a negative effect on organizational commitment and job satisfaction mediated the relationship between empowerment and organizational commitment. Finally, job stress mediated the relationship between empowerment and organizational commitment. And the results of this study suggest that the employees' job satisfaction and organizational commitment can be enhanced using empowerment in the remote management system.

DIFs (Data Interchange Formats) are needed to enhance interoperability of physically distributed organizations in SBA (Simulation Based Acquisition) process. DIFs play a role as a template of DPDs (Distributed Product Descriptions) and provide capability to use information directly without data format interchange process by allowing access to DPDs, which include various information and M&S (Modeling & Simulation) resources. This characteristic is essential for interoperability in ICE (Integrated Collaborative Environment) based SBA. This paper proposes a framework for the DIF and outputs from each phase of acquisition process for configuration data related to design and manufacturing in SBA process - Conceptual Data Model, Logical Data Model, Physical Data Model and Physical DIF based on XML. Finally, we propose the DIF model architecture and demonstrate the implementation of DIF example based on it.
