The aim of this study is to create smart wear that brings out the perspective person's individuality and creativity wearing these garments through various interactions. It is intended to build a prototype for a "Shape-folding Dress", which is length-adjustable skirt that responses with the environment of the wearer. In this process, four basic physical properties can be identified with fabric samples selected which are relatively stiff, including fusible interlining, organdy, silk, and ramie. In addition, two types of folding pattern specimens, "Basic Pattern" and "Diamond Pattern", and heat-steam were used to make the specimens so that the correlation could be calculated by recovery rate among flexing, stiffness and tensile properties. As a result, compared to other fabrics, the silk showed low stress to repeat folding and unfolding process, and its recovery rate of elongation deformation was stable without being affected by the different folding types and twice repeated process. In this study, forming a circuit using an Arduino, illuminance sensor, motors, and pulley, the prototype was created with a silk fabric.

This study presents thickness optimization for the pressure vessel domes subject to internal pressure and axial force simultaneously. The considered typical pressure vessel domes are ellipsoidal and tori-spherical domes with skirt and nozzle part. These pressure vessel domes under loading have higher stress concentration on geometric discontinuity parts. Therefore, thickness optimization of axi-symmetric pressure vessel domes is essentially concerned on minimizing this stress concentration. The objective function is minimization of weight of pressure vessel dome. The design variable is thickness of dome and cylinder. Considered constraint is Von Mises equivalent stress. In the optimization procedure, ANSYS code is used. The equivalent and hoop stress of original shape domes are compared with those of optimal shape domes. And optimal thicknesses for pressure vessel domes are presented.

The purpose of this study was to investigate the general distribution trend of drapery according to the material of flare skirt and the body size. 100% polyester and 100% rayon fabrics were chosen to compare the effect on the material type. The results from this study were as follows. (1) Both materials generally had similar trend of drapery (2) The difference of material influenced the shape and the amount of drapery. The amount of drapery in polyester was more than the one in rayon. (3) Rody size didn't significantly influence the shape of grapery. So it is concluded that material type is more important variable than the body size for the drapery.

In this study, thermal stress analysis by shape of piston head was conducted to investigate the shape of a durable piston. As the result, the farther the temperature is from the part where the temperature is applied, the lower the temperature can be seen. Depending on the shape of the piston head, the heated area became different. So, it could be seen that it affected the piston column part and the skirt part. This study showed that three models produced the least stress from the center of the piston head in the same way. Model A showed the smallest stress resulting in the yield compared to the other two models. Model B is a plate type piston head with a concave shape of the piston head, indicating that it is the model that has the least effect on the surrounding area at the center of the piston head. Model C showed the greatest stress resulting from the yield. The results of this study are also thought to be useful for designing the shape of durable pistons. By utilizing the thermal stress analysis due to piston head shape, this study is thought to conform with the aesthetic design.

Variations of individual hip shapes are a major obstacle in pattern making for fitness. The drafting method is used for pattern making in today's apparel industry. Whilst catering to a limited number of information such as waist and hip sizes, this method does not cater to variations in hip shape. This paper describes the analysis of hip shapes using 3D body model and tries to make sure the relationship between hip shape and pattern by calculating hip angle and dart amount. We achieved results in analyzing various hip shapes by extracting hip angle. Moreover, various hip shapes can be divided into three types(A, B and C) by the hip angle value($K_{sh}-K_{wsh}$). When we use computerized draping method to make a personalized pattern for a tigth skirt, we easily create complex dart lines automatically. Therefore we achieve the result of individual dart amount such as distance between dart lines and dart areas. C type of hip shape had short dart length, long distance between dart lines and a large amount of dart area. On the other hand, A type had long dart length, short distance between dart lines and small amount of dart area. B type had long length and long distance between dart lines and large amount of dart area. In traditional pattern making, distance between dart lines is usually proportional to amount of dart area because of similarity in dart line shape. In our pattern, there is no proportional relationship between dart line distance and dart area. This means that variations in hip shapes result in a wide variety of dart line curvature resulting in a wide range of dart area. By ensuring an accurate relationship between hip shape and pattern, it is possible to make patterns which result in clothing that not only fits well, but also exhibits other desirable properties.

This study's purpose is to, first survey the traditional children clothing, clothing which doesn't get studied mostly. Second, to choose the factor that can modernize. Third, to design the present one-piece dress. Fourth, to gather an understanding about traditional children clothing and make a chance for children to wear the clothing that has a traditional factor. Traditional children clothes have a same shape with adults' clothes they use five primary color and use a pattern of a symbolic meaning which means healthy and long life. For ordinary wears there are Chimajogori and Bajijogori and for ceremonial dresses they wore Durumagi, Sagyusam which are Po and Dangui and headdress was added. The shape was considered by the children growth condition so the Gorum got longer. The dragon, cicadas, butterfly, phoenix and lots of flower pattern was used by the difference with the class. 5 one-piece design adapted Jogori, skirt, Dangui, Sagyusam, Magoja and used the traditional fabric by mixing the five primary color and the five secondary color was used to make traditional color. This study expects for a chance of children to wear traditional Hanbok or Hanbok-adapted clothes.

Oscillating wave amplitude in a bottom-mounted owe chamber designed for wave energy converter is investigated by applying characteristic wave conditions in Korean coastal water. The effects of shape parameters of OWC chamber in a view of wave energy absorbing capability are analyzed. Both experimental and numerical approaches are adopted and their results are compared to optimize the shape parameters which can result in a maximum power production under given wave distribution. The experiment was carried out in a wave flume under 2-D assumption of OWC chamber. In numerical scheme, the potential problem inside the chamber is solved by use of the Green integral equation associated with the Rankine Green function, while outer problem with the Kelvin Green function taking account of fluctuating air pressure in the chamber. Air duct diameter, chamber width, and submerged depths of front skirt and back wall of chamber changes the magnitude and peak frequency of wave absorption significantly.
