The purpose of this study was to analyze the types and meanings of calligraphy presented in modern fashion design. Calligraphy refers to beautiful handwriting or fine penmanship in the West, and handwriting with brushstrokes in the East. The expression patterns being used at present can be divided into three categories. Legible calligraphy is focused on readability more than embellishment. Decorative calligraphy places its importance on decoration at the expense of practicality. The third type, harmonious calligraphy, pursues decorativeness and legibility at the same time. Each of these types of calligraphy is expressed in modern fashion with its own purpose: calligraphy for conveying emotional messages, calligraphy as a special brand image, and calligraphy as an expression of formativeness. The first, calligraphy for conveying emotional messages, is used with characters that are familiar to the public. Calligraphy of this type delivers messages confined emotionally to the conscious world, harmonizing calligraphy with words, or expressing readability filled with purity and delight. Second, calligraphy as a special brand image refers to transmitting a distinctive brand image from other companies through employment of a design motive or pattern by expressing the brand logos or names of designers. Third, calligraphy as a expression of formativeness has the function of shaping expressions as motives or patterns, avoiding meanings of words or phrases. It can be represented by the abbreviation or modification of words, or arranging words in different shapes, harmonizing the words with the clothing construction and atmosphere of the other images.

This study attempts to adapt and develop Korean prehistoric petroglyphs into textile design for children. For this purpose, literature review was conducted to understand the plasticity and symbolism expressed in Korean prehistoric petroglyphs. Also this study conducted textile design development as follows: First, the figures and faces in petroglyphs were selected because children can easily recognize them. Second, two groups of different ages (7-9 and 10-13) were allowed to freely draw the selected motifs. Third, some of the motifs created by the children were selected that show children's individuality and also keep the features of the original motifs. The children's motifs were developed into textile design using Texpro and Photoshop. Then digital textile printing and 3D mapping program were used to make pajamas (5 types), umbrellas (3 types), and simulate bedding sets (2 types) for children. This research's results are as follows: First, petroglyphs are symbolic language of human's oldest art form, and related to religious and mythical belief. Korean petroglyphs have plasticity showing the development steps in technique and expression, with various shapes such as animals, human figures, faces, masks and abstract figures. Third, children showed their interests in various human figures and faces of the petroglyphs, and it was easy to draw those motifs in their own way. Fourth, 10 design motifs were selected from the children's work and used to create textiles considering materials and colors for children. Total 10 items were made and presented. This study confirmed the usefulness of applying prehistoric petroglyphs to children's textiles designs. These designs may grow as a kind of cultural product for children who know about and like petroglyphs. They can be a niche market items too, made to order for children with individuality and who favor originality.

Considering the fact that the fit for men's clothes is important for the sizing system modern ready-made pants, an analysis of obese middle-aged men is required at this period of time to determine the appropriate fit for obese men. The following research focused on 635 middle-aged obese men who had a BMI index of at least 25 and a waist circumference from the belly-button level of 34 inches or more. This research deals with the articles of circumference, thickness and other major physical changes that happen during the 30s, 40s, and 50s. According to the analysis of these body measurement articles with specific regard to age, men's height and the height of their waist seemed to decrease as their age increased. This demonstrates that as these men grow older, the waist and stomach slowly curved into a circular and flat body type due to their obesity. In this study, the first factor figure was the height and leg length. The second factor figure was the waist form. The third factor figure was the center thigh circumference. The fourth and fifth factor figures were the hip length and shape. Lastly, the sixth factor figure was the calf circumference. These 6 factor figures construct 80.57% of the volume explanation and showed 3 patterns through a cluster analysis that showed different patterns of obesity forms for waist circumferences in key figure 1, waist and thigh circumferences in key figure 2, and waist and buttocks circumferences. Therefore, it was worthwhile to consider the circumferences of the waist, buttocks and thigh according to the body type category to enhance the drafting of well-fitting pants.

The transient vibration test and synchronized human excitation is performed for low-rise concrete buildings and their identified natural frequency, damping ratio, and mode shape are compared. Form the identified dynamic parameters, it was found that the damping ratio obtained through the synchronized human excitation test is greater than those obtained from the transient vibration test. However, the mode shapes of the first mode are not significantly different regardless of the test method. Further, the stiffness of the interior brick partition considerably affect the stiffness of the entire building such that the first natural mode of rectangular shaped building occurred in the longitudinal direction rather than transverse direction.

The pattern cases for Korean traditional socks are named "beoseonbongip" which means a pouch to keep patterns for making "beoseon". "Beoseon" is Korean traditional socks. This study is to identify characteristics of the pattern cases and to develop cultural products based on the unique characteristics of the pattern cases. One hundred fifty one photos of "beosonbongip" were collected and quantitatively and qualitatively analyzed. Seventy percent of them were made between Joseon Dynasty and 1960s. As a result, most of the collected pattern cases are rectangular and square shapes, red color, and silk fabrics, and sizes of them are from 9cm to 15cm. A few pattern cases with different sizes and colors were also observed. Most pattern cases were made by fixing two among four triangle pieces which made by folding four tips of a rectangular or square cloth and then puting a not or a loop on the remaining triangle pieces in order to open and close the pattern cases. In a small number of the pattern cases, three of the four pieces were fixed and a button, a bead, a broach, or two nots or two loops were put on the other piece for opening and closing. Products such as apparels, bags, pouches, frames, and key holders were made using "beoseonbongip" form and construction method. This shows that "beoseonbongip" is a useful motive for creative product development.

With a long crotch length and much ease in the hip area, baggy pants are visually expressed in a variety of designs when compared with regular pants. The purpose of this study is to define the image differences of various baggy pants designs according to hip circumference and crotch length ease. To that end, this study deduced the visual image variable of experimental baggy pants and analyzed visual images according to changes in hip circumference and crotch length. Nine baggy pants with different levels of hip circumference and crotch length ease were produced as experimental pants. The image of each pair of experimental baggy pants was evaluated based on pictures taken of the pants worn by a woman in her 20s with a standard body figure. The image assessment team was composed of 105 clothing majors. The research results are as follows. Four visual image factors of experimental baggy pants were extracted: whole body compensation, lower body compensation, hip compensation, and waist compensation. Among the 4 factors, the whole body compensation factor was shown as the most representative factor. The body compensation image was higher with less hip circumference ease in the experimental baggy pants, and more hip circumference ease created the optical illusion of a larger body figure, presenting a significant difference between waist circumference and hip circumference. The lower body compensation factor, hip compensation factor, and waist compensation factor all showed a significant influence on changes in hip circumference ease. This result shows that changes in hip circumference ease exerted more influence on the body compensation image than did changes in crotch length ease. The results of this study provide basic data for predicting visual images according to differences in the level of ease in baggy pants, helping people select clothing suitable to their preferences and body shapes.

In this paper, a practical procedure for the design optimization of tubular-steel-pile-type substructure in a mooring dolphin is investigated and numerically evaluated. In the finite-dimensional optimum design formulation, geometry and cross-sectional shapes of classified group of piles are identified as design variables. The design objective is the total weight of piles, and the design constraints on stresses, penetration depth, and size limits are imposed. Several classes of practical design alternatives are sought through the linking and fixing of design variables. Among the available numerical optimization codes, both PLBA program and DNCONF subroutine in IMSL library are used. They are based on SQP algorithm and relatively easy to get. A dolphin of numerical example has 20 tubular steel piles, 4 vertical and 16 inclined. Optimum designs for different cases are successfully obtained for the practical purpose.

Bridges are designed and constructed as infrastructures in order to overcome topographical obstructions for fast and smooth transfer of human/material resources. Therefore the shape and size of piers constructed along the longitudinal bridge axis should be restricted by topographical conditions. Action forces of connections and piers are affected by pier shapes and sizes together with connection arrangement which decides load carrying path under earthquakes. In this study a typical bridge is modelled with steel bearings and reinforced concrete piers and seismic analyses are performed with analysis models with different arrangement of steel bearings and piers. From analysis results ductile failure mechanisms for all analysis models are checked based on strength/action force ratios of steel bearings and pier columns. In this way the influences of arrangement of connections and piers on the earthquake resistant capacity of typical bridges are figured out in view of forming ductile failure mechanism.

The “Jeungbosallimgyeongje” was literature reviewed about the manufacture of Korean sauces. Furthermore, in order to investigate the changes made by time period, other literatures, “Eumsigdimibang(1670s)”, “Sallimgyeongje(1715)”, “Gyuhapchongseo(1815)” and “Choson­mussangyorijebeop(1930)”, were compared. The ingredients mentioned included soy beans, flour, barley, elm trees, red beans and blue beans, etc. In addition, the shapes and sizes of dried soybean paste brick were varied. “Manchojang”, which designated the kind of hot pepper paste, appeared in this book for the first time. During its manufacturing process, it was characteristic to add dried bean paste, sea kelp and fish to produce a novel and higher quality product. From the above mentioned books, we found out that Koreans used only the soybeans and Chinese a mixture of buckwheat, flour and barley in addition to soybeans to make their traditional sauces. According to the“ Gyuhapchongseo” , there was a slight difference in ingredients to add for the manufacture of fish sauce, but the manufacturing methods and the one year period needed for maturing the ingredients were the same.. However, in the “Chosonmussangsinsikyrijebop”, fish sauce and meat sauce were classified separately and their manufacturing methods were different as well. In conclusion, the ingredients of used for the sauces recorded in “Jeungbosallimgyeongje” were various and at first hot pepper sauce made from “Manchojang” appeared and additionally red peppers were added to five kinds of Korean paste and red pepper powder were added to two kinds of Korean paste. The manufacturing method of the sauces changed according to time period, for example, only soybean has been used in Korean traditional sauces and other ingredients used as for Chinese ones eventually disappeared.

The method of cross-section analysis for different sections in a structural frame has been widely investigated since the 1960s for determination of sectional capacities of beam-columns. Many hand-calculated equations and design graphs were proposed for the specific shape and type of sections in pre-computer age decades ago. In design of many practical sections, these equations may be uneconomical and inapplicable for sections with irregular shapes, leading to the high construction cost or inadequate safety. This paper not only proposes a versatile numerical procedure for sectional analysis of beam-columns, but also suggests a method to account for residual stress and geometric imperfections separately and the approach is applied to design of high strength steels requiring axial force-moment interaction for advanced analysis or direct analysis. A cross-section analysis technique that provides interaction curves of arbitrary welded sections with consideration of the effects of residual stress by meshing the entire section into small triangular fibers is formulated. In this study, two doubly symmetric sections (box-section and H-section) fabricated by high-strength steel is utilized to validate the accuracy and efficiency of the proposed method against a hand-calculation procedure. The effects of residual stress are mostly not considered explicitly in previous works and they are considered in an explicit manner in this paper which further discusses the basis of the yield surface theory for design of structures made of high strength steels.
