The purpose of this study was to analyze the direct measurement data of 20-25 years male university students of 7th Size Korea data and to characterize and to type the body shape of lower body. It was to provide basic data for male university students' pants pattern production. The lower body part consisted of the 'horizontal factor' of the lower body composed of circumference, thickness, width, and 'vertical factor' of the lower body composed of the length and height. This was consistent with the analysis of the body shape factor of the lower half of male adolescents. The lower body shape was classified into four types. Type 1 was thick and relatively long in the lower body and was named 'thick long leg'. Type 2 was named 'short bird legs' because the lower body was thin and relatively short. Type 3 was relatively thin and long, so the lower body was named 'long crane leg'. In Type 4, the lower body was relatively thick and short, which means 'short pillar leg'. In the case of 20-25 year-old male university students, they have different body shapes depending on the girth and length of the lower half of their body as they have reached adulthood. Therefore, it would be necessary to provide a sales system that allows the repair of the length of the pants to be facilitated, and the length of the pants to be repaired when the pants are selected according to the circumference. Future studies will need to classify the body shape according to angle and flatness.

Recently, the quality and design of the children's wear is being improved remarkably. Following the trend, the need for the research on the pattern making of children's wear is growing. At first, we tried to find out how the industry is doing the pattern making job through interview. Results are as follows. The target age ranges from 5 to 11 years old. For the sample size of pattern making, 7 years of age is preferred. It is not usual to develop the design pattern from the bodice block pattern. Instead, they use middle block pattern for each item, such as blouse, shirt, pants, skirt or jacket. Starting from these middle block pattern, they prepare individual designs. With the results, the aim of the research became to develop one of most frequently used middle block pattern. The blouse block pattern was selected for that purpose. To look into the existing patterns, we selected 4 methods, i.e. NM-method, T-method, O-method, E-methods. Theses patterns were compared through wearing test for the evaluation of comfort and fit using trial garments. The results indicated the NM-method was best among them. Specially waist line position, shoulder shape and size allowance was adequate. Alteration and adjustment of pattern draft was made onto the NM-method. Allowances for the bust circumference, across chest, across back and depth of arm was adjusted for better comfort as well as fine fit. Sidelines of the bodice and the underarm seam of the sleeves were curved for styling. After another wearing test, the final pattern was suggested as a blouse block pattern for 7 years old girl.

In recent decades, a lot of noise barriers have been installed along paved road in order to reduce the road induced noise, which increases as traffic volume grows. For better range of sight, transparent noise barriers are widely installed despite of reflecting noise. In this study, the effect of surface shape and pattern of noise barriers on the reduction of reflecting noise was analyzed to maximize the noise reduction. According to the number of shape and pattern, it was observed that there were noise reduction effect as of 0.9~1.5 dB(A). It was found that the spatial field where the noise concentrates or disperses changes according to the width of blocks on the barriers as well. It suggests that there might be possibility of surface shape modification to optimize the noise reduction technology.

This study is considered about the Taekwondo(跆拳道) uniform classified by period and analyzed the current Taekwondo uniform. And founded on this contents, new designs of uniform, that a functional side are considered and can symb이ize the identity of Taekwondo, are presented through this study. Ancient times to the present time, the Taekwondo uniform classified into three types according to 'Period of putting on our nation's costume'(three kingdoms${\sim}$Joseon(朝鮮) times), 'Period of confusion on uniform'(Japan's colonial rule of Korea${\sim}$-the early 1970s), 'Period of the settlement on official uniform'(the late 1970s-the present time). And besides, the shape of our nation's costume in ancient times is succeeded until Joseon times and this basic style becomes the outset on the current Taekwondo uniform. The designed uniforms are connoted the notion of the aesthetic appreciation in Korean traditional costume, that is, a symbolic, dignified, moderate appreciation with the consideration of a functional side for Taekwondo. And the contents on the presented designs are classified into 'shape, pattern, color'. First, these designs that are adapted the shape of Baji(바지) Jeogori(저고리)-belt, which have symbolized our nation's costume, and the shape of Bacja(배자) had used in Joseon times, are connoted a 'traditional appreciation with functional side'. Second, these designs, which are adapted the patterns of the active image(a bugbear, flying horse, tiger for embroidered patches, Taegeuk(太極)) in a modern style, express a 'symbolic, dignified appreciation'. Third, these designs are well-matched a black and white color with multicolored stripes(saekddong, 색동), and its ones are connoted a 'moderate and symbolic appreciation'.

The purpose of this study presents bra pattern using the 3D measurements of the upper body subject to women in their 30's. Brassieres available in the market are mostly designed for straight body shape and many women seem to have experienced bearing discomfort in a great extent as they grow older. Brassieres should be designed to cover diverse body types and the accurate measurement of body type and breast shape is needed to accomplish that. As for the study method, 3D human body types were analyzed with RapidForm 2006, and the upper-body types and breast shapes were statistically classified through technical statistics analysis, cluster analysis, t-test, variance analysis, and cross analysis. The wearing tests went through the comparison of the brassieres of three makers in the market and the experiment brassieres(first and second) and then the evaluations were made by the subjects, the outer appearance assessment by experts, and 3D measurements. The results of this study showed that the evaluation of experiment brassieres was excellent in every item, and the significant difference was found out particularly in the items of pressure, rear center, front center, breast underneath, adequate level by wing, and adequate level by armhole. According to the results of 3D evaluation, experiment brassieres had a highest point in fitness with no physical pressure at the wing part and no overall deviation at the cup part.

This experiment was conducted to characterize the inheritance of petal color, flower-eye color, flower shape, leaf variegation pattern, and leaf-end shape in Cyclamen persicum. The segregation of $F_2$ and backcross populations from crosses between inbred lines was tested for Mendelian inheritance mode. From four different combinations of crosses, it was found that the petal color was controlled by a single incomplete dominant gene. The other characters, flower-eye color, flower shape, leaf variegation pattern and leaf-end shape were confirmed to be controlled by single complete dominant genes.

The taxonomic list of specific features in external and internal shape and the pattern analysis of Aconitum carmichalei $D_{EBX}$ as the original plant of Aconiti Lateralis Radix Preparata and Aconitum cliiare Dc as the original plant of Aconiti Ciliare Tuber are as follows. 1. Aconitum carmichalei $D_{EBX}$ has tri-palmately parted leaves, petiole in lower leaves, and its ovary has short hair. Whereas Aconitum cliare Dc has $3{\sim}4$ parted leaves, long petiole, and its ovary has not hair. 2. Aconitum carmichalei $D_{EBX}$ has cylinder shape is relatively small in length and diameter, is greyish brown blacky brown in outer surface, greyish $white{\sim}dark$ gray in section. 3. According to the collection place, there is a remarkable difference in the physical shape of herbal states. Aconiti Lateralis Radix Preparate(medicated in Korea) is more transparent blacky brown color than Aconiti Lateralis Fadix Preparata(medicated in Chian). Also Black Aconi Radix(墨附片) has exodermis and White Aconi Radix(白附片) has not. 4. The internal characteristics entirely correspond to in internal shape described in the literatures, Only it is possible to discriminate between black Aconi Radix(墨附片) and White Aconi Radix(白附片) by the existence of cork layer. The classification between Aconiti Lateralis Radix Preparata and Aconiti Ciliare Tuber makes entirely Tuber makes entirely remarkable difference in the physical shape of cambium layer Namely, in shape of cambium layer the kinds of Aconiti lateralis Radix Prepala has horn-like shape and the kinds of Aconiti Ciliare Tuber has circle-like shape. 5. In the peak of examination substance in comparison to Rt of the index material diterpene alkaloid mesaconitine, aconitine, hypaconitine chromatogram Aconiti Ciliare Tuber is higher than in Aconiti Lateralis Radix Preparata This explain that the component changes after the process of medicine. 6. In the Content of mesaconitine, aconitine and hypaconitime Aconiti Ciliare Tuber is higher than Aconiti Lateralis Radix Preparata. 7. In Aconiti Lateralis Radix Preparata, aconitine, hypaconitine and mesaconitine each appears in Rf 0.46, 0.54, 0.32. But except Aconiti Ciliare Tuber the band does not appear. For the future, such results will be used as the basic source of additional research, and a far-reaching comparative study is needed to distinguish between many kinds of same genus-degree of relatedness.

When we develop the tight-fit 2D pattern from the 3D scan data, segmentation of the 3D scan data into several parts is necessary to make a curved surface into a flat plane. In this study, Garland's method of triangle simplification was adopted to reduce the number of data point without distorting the original shape. The Runge-Kutta method was applied to make triangular patch from the 3D surface in a 2D plane. We also explored the detailed arrangement method of small 2D patches to make a tight-fit pattern for a male body. As results, minimum triangle numbers in the simplification process and efficient arrangement methods of many pieces were suggested for the optimal 2D pattern development. Among four arrangement methods, a block method is faster and easier when dealing with the triangle patches of male's upper body. Anchoring neighboring vertices of blocks to make 2D pattern was observed to be a reasonable arrangement method to get even distribution of stress in a 2D plane.
