This study reinterpreted the formative design elements of traditional grate patterns to create new lattice patterns and come up with a design concept for fashion-cultural products that highlight the uniqueness of traditional Korean culture and its characteristic features. Methodologically, the computer design software programs Adobe Illustrator CS2 and Adobe Photoshop were used to make grate patterns motifs. and they were applied to scarves and again to blouses using a three-dimensional simulation technique. In this study, three basic motifs for a new formative image were set using graphical functions such as omitting, simplifying, overlapping, repeating and reducing shapes based on the images of traditional 亞-shaped, arched and floral lattices, and each motif was expanded to have two variations with different colors applied to them. The direction of basic motif design was set to fit for each of fashion-cultural items such as scarves and blouses. Basic colors for motifs were arranged to create a colorful and modern but staid image in pink, blue, purple, green, yellow and brown tones. Based on a developed motif, changes were made in blouse design with lattice patterns through a variety of effects such as repetition, rotation, cross-arrangement, and oblique arrangement, and three-dimensional simulation was used to bring the design to life. Scarf design employed and applied the existing motifs in an appropriate manner for design purposes and reconstructed them through such effects as repetition, rotation, compositional variation and gradation to express a gorgeous and refined image.

The purpose of this study is to investigate and analyse the opinions of tourists and local commercial residents for remodelling of Youngwol Gossi-cave area so that to find the way how to activate it. Therefore this study has been focused on the opinions of tourists to visit it, local merchants to sell goods and foods and officers to take charge of the control office. The present conditions of Gossi-cave area are stagnated since the service level is low by the excessive competition among the local merchants. As a result, the inner troubles have arisen among the local merchants. Therefore firstly the sustainable and future-oriented remodelling development of Youngwol Gossi-Cave area is required. And then the basic remodelling plan of participant type to be centered with tourists and local residents as the central figures through local residents' ability strengthening must be established. Lastly the basic remodelling plan through the connection of surrounding tour resources and the resource increase of local amenities must be established. Also it is necessary for the conversion as a tour place of sojourn by supplying with various shows through connections among surrounding tour resources worthy of seeing and the creation of concept to provide the excitement through the education and experience in a basic remodelling plan direction of Youngwol Gossi-cave area.

We show the novel hot electron based-solar energy conversion using tandem structured Schottky diode with double Schottky barriers. In this report, we show the effect of the double Schottky barriers on solar cell performance by enhancing both of internal photoemission and band-to-band excitation. The tandem structured Au/Si diode capped with TiO2 layer as second semiconductor exhibited improved ability for light harvesting. The proposed mechanisms consist of multiple reflections of hot electrons and additional pathway of solar energy conversion due to presence of multiple interfaces between thin gold film and semiconductors. Short-circuit photocurrent measured on the tandem structured Au/Si diodes under illumination of AM1.5 increased by approximately 70% from 3.1% to 5.3% and overall incident photon to electron conversion efficiency (IPCE) was enhanced in visible light, revealing that the concept of the double Schottky barriers have significant potential as novel strategy for light harvesting.

The High speed electrical multiple train having a distributed electrical motor system has just been developing to aim the experimental maximum speed at 400km/h since August, 2007. This project comes in stage of basic design and so, it needs to take some review and analysis the characteristics of suspensions on the view of basic design. The vehicle model for dynamic analysis is made from the concept design model that used for the preliminary design review with Vampire program and it is modeled with three linear secondary dampers and two shear springs separated from the bush elements in previous model. The optimization technique is applied to search the proper range of linear characteristics for the suspension elements to satisfy the stability performance at speed 130m/s (about 460km/h). The results shows there are some optimum points according to the variation of primary and secondary suspension characteristics and it would be useful to make a decision to select the proper suspension elements in the precision design that will be done by the manufacturing company.

A basic pulse tube refrigerator has been constructed with extensive instrumentation to study the characteristics of the heat exchanger experimentally under the oscillating pressure and the oscillating flow. This paper describes the sequential experiments with the basic pulse tube refrigerator. The experiments were performed for various cycle frequencies under the square pressure wave forms. First, the heat flux was measured through the cycle at the both cold and warm end heat exchangers without the regenerator. In order to enhance the thermal communication capability of the heat exchanger with the gas at low operating frequencies, a unique design of the triangular shape radial fin concept was applied to the heat exchangers. For the fin heat exchanger, the measured heat flux and the calculated heat flux from the two well-known oscillating heat transfer correlations were compared and discussed. Second, the regenerator was added to the pulse tube to make a basic pulse tube refrigerator configuration. The experiment showed the great impact of the regenerator on the temperature and the heat flux profiles. At the warm-end, the cyclic averaged heat flux had its maximum value at the specific operating frequency. The paper presents the explanation of the surface heat pumping effect as well as the experimental data.

The agricultural tourism is something that urban people can have an experience of the traditional culture and knowledge of the agriculture, so that it result the improvement of the agricultural profit and keep the special agricultural system. Recently, the demand of the agricultural tourism was increasing, but it was not really enough today that the practice of the tourism for essential farm experience or physical plan. The experiments were practiced by a land in Sucheong-li, Namjong-myun, Gwangju-si, Gyeonggi-do which provides the program for the basic plan and management of the experiential farm, so it shows a developmental model of that typical farm. The basic design of developmental model was formed by the analysis of the natural, civilized and visual environments. The site plan for the experiential farm was composed of a parking lot, public facilities, resting place, experiential site, sports facilities and pedestrian space. There was an examination that the activation of experiential farm should change the concept of the big production or labor-focused farm from a tourism-focused form.

I.M. Pei, 2nd generation Chinese immigrant to America, has been one of the most recognized architects who designs museum architecture through out the world for completing significant projects such as the East Building of National Gallery of Art(1068-78) as well as Le Grand Louvre Renovation(1983-89) to name a few. His museum architecture, in particular, reveals his detailed consideration on viewer's artistic experience by providing well balanced architecture design to support exhibiting objects while showing his sensitivity on overall functionality of space. In recent projects such as Miho Museum in Japan, Suzhou Museum of China, and Museum of Islamic Art of Qatar, reveals his growing interests in considering "local context" in museum architecture. Therefore, the purpose of this study is focused on analyzing I.M. Pei's three museum projects having its concept focused on local context. Through out the paper, above mentioned museums were analyzed and compared to summarize his design characters and concept including site plan, spatial organization and architectural form. As a result, it is evident that I.M. Pei had put full effort to apply oriental context with modernism through out his museums. In particular, his site plan, spatial organization, and architectural form shows visible connection to comply with nature which is fundamental idea in oriental philosophy. While his basic design philosophy has been borrowed from the tradition, his ultimate design concept shows nature friendliness as well as theoretical system of thoughts and emotion and most of all, his design excellency in representing local context.
