This paper proposes a systematic design method for axial(or thrust) magnetic bearings using optimal design methodology. The objective of the optimal design is to minimize bearing volume. The constraints include the bearing load capacity, linearized bearing stiffness and damping, the magnetic flux density, and geometric relations. In order to obtain design values which can be applied to fabrication of bearings, branch and bound method was introduced in the postprocessing procedure of optimal design results. Verification of the proposed design methodology was perfomed by an example.

Because 6sigma is doing innovative success In management whole, estimate that can exert direct effect in interior Design management. Therefore, this study did by purpose that 6sigma that is scientific method that do customers satisfaction by ultimate purpose acts as basic study that can heighten practical use Possibility and result of interior Design management and value by interior design standardization process. Need to use marketing data that is scientific design component at schematic design step for successful interior design that can improve result. Hereupon, this study is doing to big dimension that utilizes 6sigma and makes standard process of only Interior Design, and did to dimension that present study phase verifies if '6sigma' is practical use possibility by intoner design process. Did by method that verification method of 6sigma practical use possibility analyzes "Information transmission efficiency improvement of department store display space" 6sigma project example. When see that example project is analyzed on Improvement constituent that "Design improvement" out of Vital few Xs of statistical analysis item must heighten the customers satisfaction rate conclusively, target process might be established because design becomes center of gravity if did design improvement very first time. Finally, possibility that 6sigma can utilize in process of interior design is verified, and it is scientific methodology that can utilize to all business members that there are not any special category of business even if is in practical use. Such scientific 6sigma method need persistent study that make standard process analyzing a lot of problems that is expected to be beaconed and happens substantially in here after to management development of interior design.

In this study, seismic structural reinforcement are carried out, based on the estimated seismic performance of underground box structures in urban railway, and displacement based design method was developed to enhance seismic performance of structures. New seismic reinforcement design method is proposed and compared with existing design methods. And presented an overview of the developed design methodology through a design example to verify the validity of that methods.

Design verification problem is emerging as an important issue to detect any design errors at the early stage of the design. Conventionally, design verifications have been done using a simulation technique. However, this technique has been proved not to cover all potential design errors. Therefore, formal technique is often used to verify digital circuits as an alternative. In this paper we adopted formal verification technique and verified some important properties derived from our pipelined digital systems, using SMV (Symbolic Model Verifier). Our example shows that model checking method (one of formal verification techniques) can be effectively performed in verifying the large digital systems.

A known nonlinear compensator design approach is adapted to allow design of nonlinear lead and/or lag compensators, and a number of MATLAB functions are developed that automate the compensator design procedure. With this design tool, control engineers would be able to rapidly design nonlinear lead and/or lag compensators. An example of a tutorial nature is presented.

This study is one of studies which refer aesthetic characteristics and relationship about Korean traditional architecture. In this rapidly changing society, it is worthy to recognize our traditional aesthetics from which we may get a solution for improving our surrounding. The major purpose of this study was to present a holistic framework to understand aesthetics of Korean traditional architecture in a viewpoint of relationship. As a secondary purpose with this framework, Gyeongbokgung which is one of Korean traditional palaces in Chosen dynasty was analyzed and appropriate case example images were gained. Through this process, the framework could get better capability to persuade relativity of this study by showing relevant example. Through the purpose, the uniqueness of this study were like following; First, it referred a word 'relationship' clearly and exposed it to a systematic framework. Second, it referred space characteristics and aesthetics characteristics of Korean traditional architecture synthetically comparing with that other literatures referred the characteristics partially focused on their interests. Third, many literatures showed the characteristics partially by some case examples and photos but, it showed a complete case example and appropriate photos to endow persuasive power for understanding the framework.

Flood routing is one of the most important engineering problems for the design of a spillway, and the procedures for the routing should be thoroughly understood by the engineers engaged in the planning of a spillway. There are many methods for the flood routing such as Muskingum, Steinberg, Puis, Holton, Goodrich, Rutter, Graves, Snyder, etc., which are being used in many countries. This article introduces the theory of the modified PuIs Method in detail which is exclusively being used in the Bureau of Reclamation, Department of Interior, U.S.A. Also, this article includes a routing example worked by the writter for the Ee-dong Reservoir of the Ki-ho Irrigation Association. in Kyong-gi Province.
