Hanbok Chima, a Korean skirt, with large-volume should have an archetypal drawing model for appropriate cultural and historical accuracy. In order to develop new Hanbok Chima archetypal drawings we drew a skirt by connecting height with a design structure adopted from Jeogori, a Korean jacket. As a result, an archetypal drawing was developed from which circumference of lower width of Chima, size of pleats in waist circumference, and length of Chima as well as a scheme of layering Chima and Jeogori can be obtained. In this drawing, width of Chima can increase or decrease naturally according to height. However, in case of same heights and different chest circumferences if 2.5cm of additional value is provided for every 5cm increase in chest circumference, Chima of any size can be made based on this drawing. In conclusion, given the demonstrated practicality of designing a Hanbok Chima with large-volume based on archetypal drawings, it is expected that the results of this study will provide useful scientific data for Korean costume designs.

In this study, A series of fatigue tests have been performed on the fillet welded joints of cover plates in steel plate girders in order to quantitatively assess the fatigue characteristics according to the shapes of cover plates. From the results of fatigue tests, it has been shown that the fatigue strengths were slightly different according to their shapes, but satisfied the fatigue design curves in Korea and other countries. Also, from the results of beachmark tests, it has been confirmed that the points of fatigue crack initiation were closely related to the shapes of weld bead toes, and fatigue cracks simultaneously initiated from several points in weld bead toes have been grown as semi-elliptical surface cracks, and these cracks have been coalesced each other, and grown as through thickness cracks, and finally reached to fracture. Besides, from the results of fracture mechanics approaches, stress gradient factors were the most dominant factors among crack correction factors obtained from the existing equations and finite element analysis, and the fatigue life on fillet welded joints of cover plates could be estimated using the relations between fatigue crack growth rate and stress intensity factor range obtained from finite element analysis.
