Jeogori, Korean jacket, can be categorized into two styles. Traditional style Jeogori is based on conventional construction method for ceremonial or festive occasions. Contemporary casual style Jeogori is based on western style flat pattern making for better fitting and functionality. Traditional style Jeogori is quite flat on human body because it is not considered the grade of shoulder line and is drawn by vertical & horizontal line. This characteristic feature causes weakness in functionality and comfort compared to contemporary casual style. Apparently contemporary casual style has better wearing comfort. Yet to most Koreans, contemporary style Jeogori seems to lack of some characteristic style of its own. This study is to find out how to make Jeogori well balanced in terms of functionality, fit, comfort and traditional style. Currently used Jeogori patterns are compared in order to select the best among them. Onto the selected pattern, several alterations were tried focused on shoulder, armhole and sleeve lines to make optimal modifications. After several comparative fitting tests, the final pattern making method was suggested.

This study intended to suggest criteria for selection of subjects by lower body shape types necessary for evaluating slacks. For this, the characteristics were examined by lower body parts which would influence the fit of slacks on 3D human body shape data of the front and sides of the lower body for lower body shaping. The frequency of subjects by lower body shape types and the boundary points for discrimination of each type were suggested so that they could be available in selecting subjects. Using the data from Size Korea(2004), indirect measurement values measured on the front and sides of the lower body among 3D human body shape data of 175 subjects were analyzed. Their height, waist, and hip circumference fell under the range of standard deviation based on the mean of women aged 18~24 years, and then lower body shaping was conducted by combining the front and side shapes of the lower body. The front of the lower body was classified into four sections: average waist/average hip type(F1), average waist/narrow hip tyle(F2), narrow waist/narrow hip type(F3) and narrow waist/wide hip type(F4) and the sides of the lower body were divided into four sections: average abdomen/average hip type(S1), flat abdomen/average hip type(S2), average abdomen/protrude hip type(S3)and round abdomen/flat hip type(S4), and thus total 16 lower body types were created by cross analysis. Besides, discriminant analysis suggested the boundary points for each shape type of the front and sides of the lower body as a criterion for deciding lower body shape type of each subject

This study is to suggest a brassiere pattern suitable to the Chinese woman by recognizing the differences among the brassiere patterns of Europe, America and Italy by comparison. Collected data was analyzed by using SPSS 12.0. 1. If seeing the length of the ordinary brassiere's wing in Korea, the mean is 31.02cm to be shorter than these 3 patterns. The length of a wing should be adjusted according to the degree of fabric's elasticity. 2. The ESMOD type shows a high angle of $60^{\circ}$ as the position of a shoulder strip is placed outward a lot compared with other patterns. 3. For the FIT and Marangoni types, the lengths of the inside and the external diameters show similarly to each other but the ESMOD type shows that its inside diameter is 7.5cm and external one is 9.6cm to have the difference of 2.1cm so that it is considered to put the bust together stronger than the others. 4. The cup circumference of the FIT pattern shows to be the biggest and that of the FIT pattern is the smallest. As the FIT pattern has the shape to wrap the side of the bust, it has large circumference but as it has a narrow angle of a dart, it seems to be fit to the woman with a small and flat bust. 5. For 1/2 of the nipple distance of the brassiere for the Korean adult women, it shows to be 6.12cm, much narrower than the patterns studied, and it is noticed that the ESMOD pattern is very similar to the brassier in the Korean market. 6. As the mean keeper height is 6.5cm, it is noticed that it is very similar to the brassier for the Korean adult women if comparing that the brassiere for the Korean adult has the keeper height of 6.5-8.6cm. The Marangoni pattern tends to have a little low and the ESMOD and FIT patterns have a ordinary measure.

Proteins in highly oriented lipid bilayer samples are useful to study membrane protein structure determination. Planar lipid bilayers aligned and supported on glass slide were prepared. These stack of glass slide with planar lipid bilayers are not well fit for commercial solid-state NMR probe with round coil. Therefore, homebuilt solid-state NMR probe was built and used for a stack of thin glass plates and RF coil is wrapping directly around the flat square sample. The overall filling factor of the coil is much better and the large surface area enhances the extent to orientation by providing uniform environments for the phospholipids and the high ratio of circumference to area reduces edge effects. $^1H\;and\;^{15}N$ double resonance probe for 400 MHz NMR (9.4T) with a flat coil (coil size: 11 mm ${\times}$ 20 mm ${\times}$ 4 mm) is constructed and tested.

The purpose of this study was to develop the pattern of scuba diving suits for local men in their thirties by using 3D body-scanned data. It is widely acknowledged that draping method is more suitable than flat pattern for body shape as most scuba diving suits in the market are designed to fit the body tightly in a single piece with sleeves and legs. A dummy for this study was made based on men's standard clothing sizes in 30's which was derived from data of 2004 Size Korea. Accordingly, the basic body block was built upon through draping method. Next, a scuba diving suit was made from neoprene, followed by fit and the clothing pressure tests in order to evaluate the diving suit's functionality and comfort. The results of the fit test had high points of 4.33 in majority parts except armhole and crotch ones. In comparison of clothing pressure between wearer and dummy, the clothing pressure of wearer was indicated relatively low in most parts other than armhole and knee, resulting from cushion function of skin and muscle and high stretch of fabric.

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.

The object of my research is to inquiry into the immediate constituent and techniques of underwear after looking into basic theory of underwear, techniques by materials classified according to the matter of elasticity, and studying flat pattern and draping which are basis of corset and brassiere structure focusing on corsetry among underwears and production techniques. Various papers are referenced for theoretical study and the elements and techniques of underwear are analyzed based on photographical materials. This paper concludes as follows. To make the flat pattern of corset and brassiere fit to the body tightly, design dart two times without any space and draw smaller than the body. To support the breast sufficiently, move the side seam 1¼″ to the front panel and the seam should pass the apex in all occasions. For draping, dart should be added into short of elasticity materials in the past but dart is no use these days since the material today is extremely elastic. It is possible now to show the body line with only the seam or a pattern. In a case of elastic material, set the elastic direction to the grain line and have a draping as pulling from the center to the out side. As production technic, for an hem, put a zigzag stitch in elastic materials with a 10-20% short elastic band, pulling the band. Then make 3/16″-1/4″ short inseam.

This study examined how to create 2D basic pattern of individuals by means of 3-D body figure, which is to develop a flat of individual basic pattern directly from the 3-D body scan data of each subject using that of the upper body of a male adult. In terms of methodology, this study adopted 3D body scan data on system and body to make examinations in the following steps: 1. Standard point and line were set on human body, along with 3-D definition points(feature points). 2. PB was created by modifying horizontal and longitudinal section of scan data. 3. Ways to set reserve were established in the findings of PB planar development. Respective developed flat patterns were compared with pattern findings in previous studies by means of sensory evaluation. As a result, it was found that both system and body model are basic pattern and belong to appropriate pattern as semi-tight-fit basic pattern with overall appropriate tolerances. Thus, this study came to a conclusion that it is feasible and valid to develop theories for flat development as considered herein.

To enhance the design and comfort of waist-protection corsets, this study analyzed the product characteristics of five types of posture-correction corsets that are available commercially. Additionally, subjective evaluation of the corsets was conducted on women aged 20 to 60 years, in terms of design, material preference, fit, comfort, degree of correction, freedom of movement, tightness, and convenience of front fastening. Following product analysis, the five corset types were divided into: two soft, one semi-hard, and two hard types in terms of the degree of elongation. As a result of pattern analysis, the soft type was designed to improve fit by reflecting the body curvature, whereas the semi-hard and hard types were relatively flat. Through the wearing sensation assessment, the hard type manufactured by company S was the best in terms of design, material, fit, comfort, correction degree, and freedom of movement. The soft type was average in design, material, and fit while relatively poor in the correction degree and tightness. The results indicated that soft materials, flexible bones with appropriate tension, patterns designed to snugly fit the body with large curvature at the top and bottom for better inflection, and adjustable support belts that can be double-fixed are crucial elements in improving the corset design to boost the comfort of wearing. These study results are helpful in the development of waist-protection corsets with excellent wearing comfort and design appreciated by customers.

콘택트 렌즈를 피팅하는 경우 각막곡율에 따른 렌즈의 베이스커브 및 직경의 영향을 고찰하기 위하여 각막곡율별로 stainless steel ball 및 wood ball 모형안을 사용하여 피팅 시뮬레이션을 시도하였다. 완전구면체인 steel ball에 대한 피팅은 대부분 flat fitting으로 관찰되었지만 건성안에 대한 피팅 관찰용의 정량적인 모형안으로는 적합하였다. 사람의 안구와 유사한 형태의 wood ball에 대한 렌츠피팅의 형상은 실제 안구에 대한 피팅 형상과 결과가 거의 유사하였다. 콘택트렌즈의 최적 피팅(normal fitting)에 요구되는 각막곡율과 베이스커브(B.C)의 관계는 다음과 같이 정리할 수 있다. 즉 각막곡율 7.6mm 이하에서는 B.C 8.4mm, 각막곡율 7.6~7.8mm에서는 B.C 8.4~8.5mm, 각막곡율 7.8~8.1mm에서는 B.C 8.6mm이다. 또한 평균 각막곡율이 7.6mm일 때 안구돌출이 심한 경우 피팅 렌즈의 B.C는 정상안(7.6mm 각막곡율)의 B.C보다 0.1~0.3mm 더 커야 하는 것으로 관찰되었다. 지나치게 얇은 렌즈를 건성안 모형에 피팅한 결과 심하게 휘거나 뒤틀리는 현상이 발생하였다. Wood ball 모형안에 대한 피팅 결과는 비교적 실제안구에 대한 결과와 대부분 일치하지만 실제 순목 현상에 따른 피팅 상태의 변화를 감지할 수 없는 결점이 있다. 따라서 이 문제점을 포함하여 실제안구에 미치지 못하는 기타 문제점을 보완한다면, wood ball은 콘택트렌즈의 피팅에 따른 물리화학 및 유체역학적인 해석에 활용할 수 있는 좋은 도구(모형안)가 될 수 있을 것으로 생각된다.
