We compared two nondestructive methods for leaf area estimation using leaves of 16 common plant species classified into six types depending on leaf shape. Relatively good linear relationships between actual leaf area (LA) and leaf length (L), width (W), or the product of length and width (LW) were found for ordinary leaves with lanceolate, oblanceolate, linear and sagitttate shapes with entire margins, serrate margins, mixed margins with a entire form and shallow lobes, and ordinary incised margins. LA was better correlated with LW than L or W, with $R^2$ > 0.91. However, for deeply incised lobes, LA estimation using LW showed low correlation coefficient values, indicating low accuracy. On the other hand, a method using photographic paper showed a good correlation between estimates of area based on the mass of a cut-out leaf image on a photographic sheet (PW) and actual leaf area for all types of leaf shape. Thus, the PW method for LA estimation can be applied to all shapes of leaf with high accuracy. The PW method takes a little more time and has a higher cost than leaf estimation methods using LW based on leaf dimensions. These results indicate that researchers should choose their nondestructive LA estimation method according to their research goals.

It is time to create an image of Korea that uniquely defines and represents the nation to the world, by incorporating Korean traditions with the cultural industry. To this end, it is important to see the beauty of Korean tradition from an academic perspective and further explore its utility from an industrial viewpoint. This study is intended to design uniforms for employees in Korean restaurants at hotels or docents in Korean-styled museums. In doing so, we eyed on Baeja, a Korean traditional vest as the cultural archetype, and created cultural products. As our archetype, we chose two pieces of Baeja : one excavated from the tomb of Suryun Sim (1534-1589) which is displayed in the Gyeonggi Provincial Museum, and the other from Byeon of the Jeonju Lee family (1636-1731) in Suk Joo-Sun Memorial Museum at Dankook University. We also adopted Dapho with a Korean traditional vest with long length. Based on these cultural archetypes, seven products were developed. With the traditional food and way of living in Korea being more and more recognized in the global stage, it would be continuous creation and development of cultural contents with history and story rooted in the cultural heritage of the nation that could enrich our culture by bringing traditions back to the modern days to incorporate the past into the present. It is important to restore traditions when developing cultural products. However, it is also critical to commercialize ideas with stoη and creativity in the market for cultural products.

The purpose of this study was to analyze characteristics and meanings of the masculine factors related with power images in women's fashion since 2000. The method of study was to analyze the documentary about the power images since the 14th Century and then the fashion magazines since 2000. The results of this study were as follows: The power image of women's fashion was internalized by wearing of the masculine factors each of an era. After 2000, characteristics of women's fashion affected by masculine factors were an exaggeration of scale, deformation, inharmonious collage and changeful borrowing. They showed the structure of new cognition of modern society uncertainty, open and decentralized. And power images presented aesthetic characteristics such as independence, ideal, sign of a amusement and decentralized virility. In conclusion, power in women's fashion has a function of creativeness, product, positiveness from past to modern. In addition, the power, which is a symbol of perfection, rationality and ideal beauty, expresses a good feeling of psychology, social friendship, value of success and will be existed as a meaningful esthetic sign in women's fashion.

The measurement of 3D shape is important in inspecting the quality of product. In this paper, we present a 3D shape measurement system of fastener using a camera and a slit laser. Calibration structure with slits is used in the extrinsic calibration of the camera and laser. The pose of the camera and laser is computed under the same world coordinate system in the calibration structure. Reflection of laser light on the metal surface causes many difficulties in the robust detection of them on image. We overcome this difficulty by using color and dynamic programming. Motor stage is used to rotate the fastener to recover the whole 3D shape of the surface of it.

21century design is working in order to increase the accessibility, eliminating alienation hierarchy for the use of the product. Efforts to these design approach are not intended for a small number of users. It offers the advantage of a variety of design for users of a wider range. So, it was allowed to extend the value in good design for all human beings. Traditional thought is expressed in a variety of shapes by applying meaning to another re-interpretation for the form to contemporary furniture and structure and decoration. Gyeongsang have a religious solemn feeling in the typical furniture of hall space that reflects the inner distinctive tradition thought of scholar of the Chosun Dynasty. For these reasons, in the present study, based on the modeling elements of Gyeongsang, which is based on the traditional idea of our country, there is the purpose to propose a design of agreed with table in modern lifestyle. Design concept proposed in this paper, to be applied to the design of the table is placed in the living space by re-interpreting the modeling properties which can be felt in the thin form and structure and patterns as modern image.

The Roll-to-Roll system including continuous flexible thin materials and roller has its wide range of applications especially in the electronic printing industry. The industry is growing rapidly and the printing speed is also improving. However, the printing machine based on web and roller system has it own problem. As the web speed increases, the failure to maintain the contact may occur and the air entrain between the roller and the paper web may exist. Air bubbles may remain attached to electronic ink on the web causing defects on product surface. With the development of image processing technique, the airflow around the web and rolls can be visualized and calculated by PIV method. In our experiment, the simple web and rolls system is used to R2R simulator. The flow field is studied at various web speeds and positions. The result shows that the flow field has complicated structure with turbulent characteristic and the main trend of flow is obtained by taking time average of flow field.
