The study purpose was to increase Han-bok's convenience by changing materials while maintaining keep the traditional Han-bok style. For this purpose we surveyed actual Han-Bok wearers about the inconveniences of its form and design by combining knit with Han-bok. On the basis of this survey, we present a practical design for use in daily fife. Responding to the question about Jeo-Go-Ri(jacket), most respondents preferred a Han-bok which stressed elasticity by utilizing knit on Jeo-Go-Ri's front and back body line(JD1, JD4). For the question about ann holes, most respondents liked a design which substituted knit materials for Sam-hoi-jang(colorful strips) to ensure ease of use and shorten both the width and length of the breast-tie(JD2, JD3). For the sleeve edge, they preferred a design which solved the difficulties of rolling up the sleeve when working ($JD2{\sim}JD5$). Regarding the most inconvenient aspect of wearing Chi-mas(skirts), the respondents indicated tightening of the breast and an uncomfortable feeling due to the skirt length. This suggested that the waist of the vest should be lengthened to avoid the feeling of pressure(CD2, CD5). Regarding changes to the skirt shape the respondents preferred buttons and hooks rather than using skirt strings(CD4, CD5).

This paper developed motifs through the use of images of masks with which the Korean innate consciousness of aesthetics is expressed. The motifs were applied to fashion items. This paper investigated the concept, origin and types of traditional masks through the existing literature. Using the computer graphic programs of Illustrator and Photoshop CS2, three basic motifs were set from the images of the nobleman, Bune of Hahoi Tal and Byeongsan Tal. Each motif was extended into two motifs by changing shape and color. For the basic motif design, this study sought to express contemporary images, suitably for each fashion item, while maintaining the basic shape of the masks and their traditional images. In addition, this study set the concept of the design so that could be accepted by various age groups. For the design of handkerchiefs, a rotating array, involving enlargement, reduction, repetition, and the gradation of motifs, as well as a diagonal symmetric array, and all-over patterns were developed. The T-shirt design created here was divided into a half-sleeve box type, a round neckline sleeveless type, a V-neckline close-fitting sleeveless type, and a V-neckline close-fitting cap sleeve type. For the design of necklaces, OLED or LED, which are considered as a future display type, was used. Additionally, the production of an entertainment styled new atmosphere is proposed.

This paper presents the fluid characteristics of the spool actuator used for construction vehicles. A spool actuator is used for directional control of pressurized fluid and has a roll to lock the fluid flow. It is important to design the spool actuator optimally because this actuator is actuated in the sleeve by sliding motion and has some critical design parameters such as stick-slip, leakage and shock pressure. The parameters like stick-slip and leakage can be solved by precision manufacturing but the shock pressure which is taken place when the fluid direction is changed needs the parameter analysis procedure throughly. In this study, mathematical modeling and 2 & 3 phase flow dynamics analysis of the spool actuator were achieved. Using suggested model, all possible operating conditions were analyzed.

The purpose of this study was to design men's jacket pattern for variable body types by employing the data of wearing evaluation from experimental basic bodices selected by male subjects in the 30's. As a result of sensory evaluation, functional test and clothing pressure test by each type of experimental basic bodices, the 3rd experimental basic bodice was chosen to be a basic bodice type in this research since it showed a high degree in fitness and function, but a low in the clothing pressure test. As a comparison of one item from conventional jacket and sleeve pattern with each somatotype, the type 2(the standard somatotype) indicated a great fitness in both basic bodice type and conventional jacket pattern, whereas the type 1 and the type 3 showed higher fitness and moving function in the basic bodice type. In the making of men's jacket, many corrections were made in the front interscye breadth, back interscye breadth, front and back length, and shoulder line as adapting each body type. Thus, the ease-amount of chest circumference at scye for clothes should be established differently according to the size of chest circumference at scye.

The purpose of this research is to investigate elderly, middle-aged female consumers' design and material preferences for lounge wear and after understanding senescent women's propensity to purchase lounge wear. The subject of research were to those living in the Seoul and capital region and 612, which did not comprise missing values, were collected and used for data analyses. All the age groups including those in their 50s and 60s prefer jacket and pants styles the most and these styles are the most favored as lounge wear as well. Those in their 50s and 60s prefer a round neckline the most while those in their 70s favor a V neckline the most. Analyses of sleeve styles of senescent women show that all the age groups favor a straight set, or a sleeve design, the most. Although the aged people investigated in this research have relatively high purchasing power, it is found that they tend to buy low priced lounge wears. Reviewing all of the above-mentioned results, the prices of garments for senescent people will be set in consideration of their economic level, so that good quality commodities may be produced and sold at different prices.
