This study was to examine the effects of garment types on thermal insulation using a thermal manikin. cotton polyester wool silk and rayon were selected as outer wears like a blouse a skirt slacks and one-piece for this study Acetate was chosen as a lining. Brief and upper innerwear with long sleeves(cotton) were also chosen as the innerwear. The results were as follows: 1. The thermal insulation of the garment of single layer was in proportion to the covering area of garment in all types of clothing. 2. On adding the innerwear or the lining or both the thermal insulation of the each garment of single layer were showed a different trends by garment types. The thermal manikin insulations of one-piece dress adding the innerwear was higher than those of blouse-skirt suits. The thermal insulation of one-piece dress adding the innerwear and lining was lower than those of blouse-skirt suits. 3. The increasing rates of thermal insulation of multi-layered garments had different value by garment types but garment made of rayon and silk were showed very high increasing rates of thermal insulation. 4. The increasing rates of the thermal insulation of one-piece dress added the lining the innerwear or both except polyester showed the highest value and then blouse-slacks suits' turn came ound Blouse-skirt suits had the lowest the increasing rates of thermal insualition value.

The purpose of this study is to develop the formal wear for social activity of dwarf. Second investigation for choices of designs based upon data from the first questionnaire investigation, led us to make proposals for design, pattern production, garment-cutting and dressmaking. The effect of wearing the made-up garments was carefully evaluated in order to establish principles for the development of clothes for dwarf. Conclusion is as follow. Dwarf felt uneasy in conventional street dress. When buying clothes their most important criteria was design wanted clothes that would help them to look taller. Analysis of design preference to complement perceived physical weak points revealed: 'a pink ensemble' comprising of a high-waist, one-piece dress, and a black slacks suit comprising of a striped, single-breasted, tailored jacket, and straight-type slacks and blouse. It was found that a bolero jacket and a high-waist, ankle-length, one-piece dress helped create an optical illusion of increased height, for both the wearer and an observer. A pastel ton-pink, one-piece also created this effect on small bodily types, as well as offering a silky, mellow attractiveness. A suit of a striped, single-breasted tailored jacket, and straight-type slacks and blouse, created the two fold illusion of disguising hip imbalance with the length of the jacket and drawing an onlooker\`s gaze to the wearer\`s face through the tailored collar, they also looked taller due to the stripes.

In contemporary architecture, glass is being used less as a single piece for the exterior envelope, due to a variety of influences such as increased performance regulations, the market environment and technical developments. An architectural exterior wall today is usually installed as a 'ystem' wall, not as a single plane glass wall. That brings up the necessity to question the appropriateness of the materiality of an individual piece of glass for the exterior envelope in urban settings. Therefore, in many cases it is appropriate to examine materiality of glass as a system. A new examination of materiality can be carried out by analyzing the interactions between layers that constitute a system. This paper examines the experimental use of glass systems in contemporary architecture, and analyzes them to interpret the relationship between the layers of each system in order to establish the diversified materiality of glass in contemporary architecture.

Most frame structures cannot be manufactured in a single-piece form. Ideally, when a structure is built up by assembling multi pieces, assembly at the joints should be rigidly performed enough to have almost full stiffness, which is difficult for practical reasons such as manufacturing cost and time. In this research, we aim to develop a manufacturability-oriented compliance-minimizing topology optimization using a ground beam model incorporating additional zero-length elastic joint elements. In the present formulation, design variables control the stiffness of zero-length elastic joints, not the stiffness of beams. Because joint stiffness values at the converged state can be utilized to select candidate assembly locations and their strengths, the technique is extremely useful to design multi-piece frame structures. An optimal layout is also extracted based on the stiffness values.

울산 하대유적에서 출토된 민고리자루칼을 방사선 비파괴조사와 미세조직 분석으로 환두부의 제작 방법과 재질 특성을 살펴보았다. 방사선 비파괴 조사법으로(X-ray, CT) 내부 구조를 확인한 결과, 제작 방법의 기본형식은 철 단일 소재로 칼 끝부터 환두부까지 일체형으로 제작한 단조품임을 확인하였다. 또한 미세조직 분석을 통해 살펴 본 제작기술은 '순철-형태가공, 순철-형태가공-침탄, 강-형태가공-담금질'의 세 가지 유형으로 분류할 수 있었다. 민고리자루칼 5점 중 4점의 환두부는 약 0.7% 내외인 공석강 정도의 탄소 함량을 가진다. 특히 환두부에서는 손잡이보다 증가된 탄소함량을 보이는데, 이는 손잡이 끝 부분을 세장한 형태로 만들고 둥글게 구부리는 과정에서 인성을 부여하기 위한 침탄 처리의 결과로 추정된다. 길이 60 cm 이하의 민고리자루칼 1점은 날 부위에 집중시킨 담금질을 통해 강한 인성을 부여하여 무기로서의 용도를 극대화시켰다. 반면 75 cm를 넘는 4점의 날 부위에서는 담금질 조직인 마르텐사이트가 관찰되지 않았다. 하지만 칼등 대비 날 부위의 탄소함량 증가나 결정립의 미세화는 실용기로서 사용이 가능했음을 보여준다. 2C말에서 4C초로 편년되는 울산 하대고분군 출토 민고리자루칼은 단조기술을 통해 일체형으로 제작하였으며, 사용 목적에 따라 제강, 열처리 기술을 적용하여 칼이 가지는 용도의 효과를 극대화시켜 제작하였다.

Substituting composite structures for conventional metallic structures has many advantages because of higher specific stiffness and specific strength of composite materials. In this work, one-piece propeller shafts composed of carbonfepoxy and glass/epoxy composites were designed and manufactured for a rear wheel drive automobile satisfying three design specifications, such as static torque transmission capability, torsional buckling and the fundamental natural bending frequency. Single lap adhesively bonded joint was employed to join the composite shaft and the aluminum yoke. For the optimal adhesive joining of the composite propeller shaft to the aluminum yoke, the torque transmission capability of the adhesively bonded composite shaft was calculated with respect to bonding length and yoke thickness by finite element method and compared with the experimental result. Then an optimal design method was proposed based on the failure model which incorporated the nonlinear mechanical behavior of aluminum yoke and epoxy adhesive. From the experiments and FEM analyses, it was found that the static torque transmission capability of composite propeller shaft was maximum at the critical yoke thickness, and it saturated beyond the critical length. Also, it was found that the one-piece composite propeller shaft had 40% weight saving effect compared with a two-piece steel propeller shaft.

The role of fashion image in modern society is being diversified from product planning to consumer satisfaction. In this research, after surveying female college students, the diversified modern fashion image was patterned. On the analogy of the relationship between these patterned image and design factors, the following conclusion was obtained. 1. The most popular styles are jacket and pants suits, three-piece outfits, tight mini-skirts and X-silhouette. Little decoration is used in general. simplicity is shown as trend by utility fabrics in single color-black, brown, beige and blue-with no pattern. Various materials such as wool, cotton, wool or cotton blended with other materials, silk, satin, knit, lace, vinyl and leather are used. 2. Fashion image is divided into four factors; factors that show fad, dignity, activity and simplicity. 3. Factors that show fad; style of tops, material of bottoms and length of bottoms reflect fad. blousons, three-piece outfits, pants rather than skirts, X-silhouette and mini-skirts are prevailing. Vinyl, leather, knit, lace and satin are the materials well used. 4. Factors that show dignity; Style and material of tops, the way of top and bottom pieces are matched and length of bottom or pieces reveal the characteristics. Jackets, blouses, half-coats and one-piece outfits rather than two-pieces are popular. Tight skirts in natural or midi length or pleated skirts are common. Wool, wool blended with other materials, leather and X-silhouette are design factors that reveal dignity well. 5. Design factors that show active image; Straight pants, three-piece outfits, T-shirts, shirt -blouses, vests, and blausons are popular. Knit and lace are used for tops, leather and vinyl are used for bottom pieces and cotton is widely used. Y- or H-silhouette are used to show active image.
