As of today-half a century has passed after 1945, the liberation from Japanese imperialism-it's significant to introspect our culture. On the one hand our culture has succeeded due to the peculiar history, but on the other hand it hasn't. So to speak, it has gained in Quantity but lost in Quality. There are keen, international competition and exchange in the modern culture. So the Qualitive success of modern design depends on if it had an original character or not. According to Korean rapid industrialization, technological extence, and economic growth, the export has increased greatly, but package design hasn't been match for them. Korean expoters have been meeting with cutthroat competition in world market. Under these circumstances it's very important that we have a real understand and interest in our culture, we strengthen the competitive power of home products with good package design. This is our age of not home market but world market. We live in an age when design wins, so that we have to develop the good design native to Korea. Many designers have proposed their opinions with the characteristic designs, but it has been only a fragmentary and passive method. We must seek for the new method more positively. The effective and proper method resolves itself into the following four points. First, to understand Korean history and culture. Second, to have the exact grip of this economic situation. Third, to promote the national emotion. Fourth, in conclusion, to accord the package design with them. We cannot put off this task to overcome the cultural subordination, to place Korea on a firm cultural basis in the world, and to contribute to the cultural exchange of package design.

In this research, the reasonable local scour estimates considered conditions of the bed material and the flow was accomplished on two piers P14 and P17 of Il-san bridge. Especially, the Il-san bridge was located on the lower Han-river where is influenced by the tides of In-chon, and it has hydraulic condition that can cause the bridge piers local scour because of tides at ordinary times, as well as a flood. Therefore, the local scour depth has been presented influenced by the maximum velocity of the flow when a flood after construction and the tides on construction on the basis of the standards of river design and road design, furthermore, the results was made a comparative analysis. According to the results, the local scour depth on the basis of the standards of river design was higher than it on the basis of the standards of road design(SRICOS), and the local scour depth influenced by the maximum velocity of the flow when a flood after construction was determined the final local scour depth of P14 and P17 at the Il-san bridge. It was ascertained that the local scour depth did not exceed the inserted depth of bridge foundation.

The Taguchi method is applied to obtain the optimal design of an automotive pedal arm in consideration of the stiffness test specification. Design parameters are defined to describe shape of the pedal arm. Volume, maximum Von-Mises stress and maximum displacement of the pedal arm are established as the smaller-the-better characteristics. Optimal parameters are determined on the basis of the analyzed level averages of the characteristics.

산업 디자인은 시대와 환경에 의해 그 과정과 방식이 변화해 왔다. 또한 컴퓨터 관련 기술의 발전은 사람들의 사고와 생활방식에 많은 영향을 미쳤으며, 물리적이고 실체적인 제품개발에서 소프트웨어의 중요성에 대해서는 이미 각계의 많은 사람들이 공감하고 있지만 실제적인 디자인 워크에서 이러한 컴퓨터 소프트웨어에 의한 개발업무나 프로세스에 대한 이해가 부족하기 때문에 효율적인 진행이 이루어지고 있지 않은 실정이다.(중략)

Experimental and numerical investigations of the off·design performance of a simple channel-wedge diffuser in a small centrifugal compressor are presented. Surge and choke conditions as well as design point are considered using somewhat limited range of experimental data and also supplementary 3D CFD results. Some critical meanline design parameters' behavior is investigated numerically, to render the basis for improved modelings in the meanline performance prediction.

This paper concerns a development of LQ-servo PI controller design on the basis of time-domain approach. This is because the previous design techniques developed on the frequency-domain is not well suited to meet the time-domain design specifications. Our development techniques used in this paper is based on the convex optimization methods including Lagrange multiplier, dual concept, semidefinite programming.

The performance of steel MRF with rigid connections, proportioned by adopting different capacity design criteria, is evaluated in order to highlight the effectiveness of static non-linear procedure in predicting the structural seismic behavior. In the framework of the performance-based design, some considerations are made on the basis of the results obtained by both dynamic time histories and push-over analyses, particularly with reference to the damage level and the structure ability to withstand a strong earthquake.

This paper deals with the design of a microstrip line feed toppled T shaped microstrip patch antenna that gives dualband characteristics at 4 GHz and 6.73 GHz respectively. The simulation of proposed antenna geometry has been performed using method of moment based IE3D simulation software. A radial basis function neural network (RBFNN) is used for the estimation of bandwidth for dualband at 4 GHz and 6.73 GHz respectively. In RBFNN model, antenna parameters such as dielectric constant, height of substrate, and width are used as input and bandwidth of first and second band is considered as output of the network. To validate the RBFNN output, an antenna has been physically fabricated on glass epoxy substrate. The fabricated antenna can be utilized in S and C bands applications. RBFNN results are found in close agreement with simulated and experimental results.

When a cold HPSI (High Pressure Safety Injection) fluid associated with a design basis accident, such as LOCA (Loss of Coolant Accident), enters the cold legs of a stagnated primary coolant loop, thermal stratification phenomena may arise due to incomplete mixing. If the stratified flow enters a reactor pressure vessel downcomer, severe thermal stresses are created in a radiation embrittled vessel wall by local overcooling. Previous thermal-mixing analyses have assumed that the thermal stratification phenomena generated in stagnated loop of a partially stagnated collant loop are neutralized in the vessel downcomer by strong flow from unstagnated loop. On the basis of these reasons, this paper presents the thermal-mixing analysis results in order to identify the fact that the cold plume generated in the vessel downcomer due to the thermal stratification phenomena of the stagnated loop is affected by the strong flow of the unstagnated loop.
