To build a successful information system, design and development should be carried out from the enterprise perspective. A complicated business is represented in various ways as technology advances, and many development methodologies have been studied from the viewpoint of technology and development. Each domain is independently designed and developed from the enterprise perspective, but there would be inclusive parts due to the integrated process wherein the definition, design, and development of business are carried out, and the design is done based on the designer's experience. This study would like to address the technique of designing screens based on the business process of the applications derived from the business. It designs the screens that appear when actual applications are completed, including how the data transfer process in the derived business process is represented and operated on the relevant screens. It designs the screen which is displayed when the actual application is completed and how the data transfer process in the derived business process is represented and operated on the relevant screen. In addition, it designs the DFD representing the overall flow of data for each business to represent the movement procedure between screens in general. Through the design method proposed in this study, the client's requirement could be confirmed to reduce the cost for redevelopment, the problem of communication between designers and developers with various experiences could be reduced, and an efficient design procedure could be provided to persons who lack design experience.

The application of induction bending processes to industrial pipe production is increasing. The induction bending process has the effect of reducing the number of inspections and preventing leaks by reducing the weld of the pipe. For these reasons, efforts have been made to apply an induction bending process to the pipe of the PGSFR under development in Korea and this is the first attempt in the SFR design. Since the PGSFR pipe has a relatively large diameter-to-thickness ratio, it is difficult to fabricate an induction bending pipe that meets the requirements. In addition, the material properties may change because the pipe heats to a very high temperature during the induction bending process. In this study, P91 pipes were fabricated by induction bending, and the results from analyzing the induction bending process' applicability to the P91 pipe of the PGSFR are examined. The various dimensional measurements of the pipes fabricated by the induction bending process were surveyed to determine whether the requirements of the ASME Code were met. The minimum thickness, ovality, and wall buckling measured in the fabricated pipe met all the requirements. Tensile, impact, and hardness tests at various locations of the fabricated pipe also satisfied the requirements.

The purpose of this study is to confirm whether the task and system development process makes a significant influence on the system performance. The task is defined as a interdependency and system development process is defined as analysis, user participation and executive support. Field research was employed to empirically investigate the relationship among the variables. The finding of the study can be summarized as follows. The strict analysis under the task of high interdependency has a significant effect on the system performance. And high executive support is needed for the system performance under any level of interdependency.

The quality of the products/processes has been improved remarkably since robust design (RD) methodology is applied into the practice manufacturing processes. A model building method based on the dual responses methods for multiple and time oriented responses on a drug development process is employed in this paper instead of the previous methods that handle the static nature of data and single response. Subsequently, the optimal solutions of a multiple and time series RD problem are obtained by using the proposed augmented weighted Tchebycheff method that has a significant flexibility on assigning weights. Finally, a pharmaceutical case study associated with a generic drug development process is conducted in order to illustrate the efficient optimal solutions from the proposed model.

The objectives of this study are to analyze and compare importance degrees of rural amenity resources for rural development project using AHP and ANP (Analytic Network Process) which can be applied a complex decision making problem. For this study, I chose the 5 rural development project types and the 10 rural amenity resources as major criteria and formed the ANP network from relations with criteria. The importance degree matrix were derived by the results of AHP and several ANP analysis. As the results of this study, the importance degrees of 10 rural amenity resources are determined and the indigenous product resource is identified as the most important resource in general rural development project.

Configuration management plays a key role in systems engineering process for any project from earlier stage of development. It consists of five major activities, ie., configuration management planing, configuration identification, configuration control, configuration status accounting and configuration verification and audit, and is essential to control system design, development and operation throughout entire life cycle of the system development. And it is directly associated with other part of systems engineering management process, ie., technical data management which provides traceability of important decisions and changes during development. In this paper, we describe how to apply CASE(Computer-aided Systems Engineering) tool-Cradle for the configuration management to achieve effectiveness of Technical Management process.

Electron beam lithography is one of the importnat technologies which can delineate deep submicron patterns. REcently, electron beam lithography is being applied in delineating the critical layers of semiconductor device fabrication. In this paper, we present a development simulation program for electron beam lithography and study the development profiles of resist when resist is exposed by the electron beam. Experimentally, the development parameter of positive and negative resists are measured and the data is applied to input parameter of the simulation program. Also simulation results are compared of the process results in the view of resist profiles. As a result, for PMMA and SAL 601 resist, the trend of simulation to the values of process parameters agree with real process results very well, so that the process results can be predicted by the simulation.

The rapid progress of the Internet and network is affecting the engineering design environment as well as business that use Web technologies to enhance their competitive edge. In product development, experts and organization who take part in the design process are often geographically dispersed. Furthermore, different divisions and business often have heterogeneous CAD/CAE systems and methods for expressing product data, and addressing this heterogeneity creates additional costs and increases development time. Managing distributed CAD, CAE and other related systems in an organic and holistic manner from the initial stages of product development is imperative to ensure successful collaboration in the design process. Therefore, this study suggests a Web-based MDO framework to support interfacing and collective use of design and analysis tools.

In this paper Research development about a micro metal forming manufacturing system has been developed. A micro forming system has been achieved in Japan and it's developed micro press is limited to single forming process. To coincide with the purpose to be more practical, research and development is necessary about the press which the multi forming process is possible. We set the development of the equipment including micro deep drawing, micro punching and micro restriking process to the goal. To achieve this goal, we set the application product to a micro thin foil valve which is used in the micro pump module. The compound die set has been designed and manufactured to make two step process. The material of thin foil valve is SUS-304 and its thickness is 50$\mu$m. We can get a good forming results from micro punching experiments in this paper.
