Based upon literature survey and questionnaire survey, this research tries to develop four new Cleanroom Garment in semiconductor industrial environment. The designs emphasize to minimize workers disconmfort so that they can not only cover human body fully but also reduce dust as much as possible during work hour in clean room. The new designs characteristics and results from both function test and dust emission test are as follows: 1. In order to reduce dust-emission, we develop new designs with hood, kimono sleeve, and back zipper. The designs with hood face positive test results in term of motion suitability and dust-omission. The design with seam in front, in particular, is effective to control dust-emission. 2. For the purpose of reducing dust-emission, we also emphasize to minimize ease of dust-proof wear, with reference to previous research and clothing experiment. The experiment participants report that the new wears are not so comfortable as existing ones, but they accept the new wears positive as effective in reducing dust-emission owing to reduced ease of Cleanroom Garment and sleeves. 3. A1so to reduce dust-emission in inner wear, we put inner wear in both Cleanroom Garments and inner wear, resulting to remove discomfort of wearers when changing clothes and of tight waist due to inner-trousers. 4. We develop new designs with elastic bands in both waist through the side lines and with velcro only at the back side. To remove twist in front contributes to reduce emission arising out of friction, also to free the appearance minding woman workers from worrying about exposed stomach. The new designs need to be accepted as a valuable alternative of Cleanroom Garment, in that they are highly effective to reduce dust-emission, which is the most important factor in the wear, in spite of some drawbacks in terms of motion-suitability, ease and appearance as shown in wearing test.

The purposes of this study are to verify the sales promotion effect of bargain sale of department store, and to investigate the relationship between the effect of bargain sale and the consumer attitude toward economics. For those purposes, secondary data was collected. The data was composed of monthly sales data of women's casual wear, men's suit, inner wear, infant's wear, and golf wear in a department store from 1996 to 2003. The data on consumer attitude toward economics was collected from 'Consumer Attitude Index' issued by SERI. The results are as follows. First, there were differences in the sales promotion effects of bargain sale by merchandise class and by year. Men's suit was the class that the effect was highest, and inner wear was the class the effect was lowest. In addition, the effects were simultaneously lowered by year. Second, sales promotion effect of bargain sale had relationship with consumer attitude index. The yearly transitions of the two data were almost similar. This means that as the consumer attitude becomes pessimistic, the motivation to consume also becomes lower, so that sales promotion effect of bargain sale also decreases. In addition, women's wear and men's suit showed the most similar transition patterns with the consumer attitude index.

In this research, the curly dock was used in the process of dyeing for fabrics of the inner wear & the patient wear. Since the curly dock has a pharmacological effect on dermatosis, this study focused on the variety of color and functions of the inner wear fabrics & patient wear fabrics to make the best use of the pharmacological effect of curly dock. With regards to giving a variety of colors and functions in the inner wear, patient wear fabrics, the curly dock dye was used in each treatment conditions on the cotton & silk fabrics. After dyeing, the dyeability, color change, light fastness, washing fastness, perspiration fastness, antibiosis, far infrared emissivity and emission power were evaluated. The evaluation results are as follows; The dyeablity increased from repeated dyeing and, by using the mordant, variety of colors such as skin, mustard, greyish-brown and dark earth colors were conformed to the naked eye. Fe mordant was better than Al on the lightfastness and the washing fastness. The repeated dyeing was found out to have less effect on neither lightfastness nor washing fastness. Both silk and cotton fabrics were graded $3{\sim}4$, since their degree of degradation appeared to be the same in alkali perspiration and acidic perspiration. In the case of silk fabrics mordanted by Al, the rate of declining in both Staphylococcus aureus ATCC 6538 and Klebsiella pneumonia ATCC 4352 were 99.9%. In addition, the antibiosis was enhanced when the mordant was used. The far infrared was 86.6% of emissivity, $3.34{\times}10^2\;W/m^2{\cdot}{\mu}m$ emission power.

This study was conducted to improve the durability and decrease the friction of the sintered bushing used in the joints of construction equipment. Research was carried out to examine the effects of the groove pattern on the inner surface. The following results were obtained: (1) The bushing (EK Bush) with grooves on the inner diameter showed increased durability as compared to a non-grooved bushing. (2) The helical-grooved bushing showed the least amount of wear; it was １/10 of the wear of the non-grooved bushing. (3) If the distance between grooves was decreased, then the coefficient of friction also decreased.

In this paper, various structures of the healthcare smart clothing for real-time measurement of vital sign were suggested. The wearing efficiency was evaluated to find out the best ergonomic clothing in the suggested design. The supplementary effects of the clothing components (princess line, double fabric, cushion) on the stable and tight positioning of sensors to the body were evaluated with wear test. Five experimental clothing for male subject were made with closely-fitted shape and they included two representative structure: one was the integrated type of inner and outer garments and the other was the separated type with two garments. Eight subjects in their twenties were participated in the wear test to evaluate the wearing efficiency of experimental clothing. As results, the clothing structure of the separated garments with the inner and the outer shells were evaluated as more efficient and comfortable. However, the effects of clothing components on the light positioning of the sensors to the body surface were not differentiated each other in the subjective evaluation.

The analysis and examination of this study are focussed on the external deconstruction trend expressed in the works of Jean Paul Gaultier. The external deconstruction is a way of expression faithful to the literal meaning of 'deconstruction' and is the applied case of exposure, destruction, poverty, and decomposition as they are. The method and scope of this study are from 1980's to present, and the followings are the results of this examination focussed on the various literature of philosophy, aesthetics and literary criticism, and the domestic and foreign fashion journals. The exposure phenomena through the deconstruction expressed repeatedly in the works of Gaultier deconstructed the fixed idea of 'the inner wear should be worn inside the outer wear' and at the same time denied the dichotomical interpretation of the exposure and suppression, the traditional beauty and decadent beauty, the chastity and unchastity, the asceticism and sexuality, and obscured the notion of the inner wear and outer wear. The destructive deconstruction expressed in the works of Jean Paul Gaultier introduced the elements such as hippy, punk, and kitsch, slashed before making dresses, crumpled unseemly like wastepaper, or made dresses with textures like paper scraps, and through destroying textures, yielded shock effects and tension. Poverty, through borrowing from the outwardly poor-looking elements of design, i.e. the patch work, decolor, dye, fading, fringing, incompletion, and handmadeness, liberated dresses and their ornaments from the outside. The traditional dresses were dresses having certain forms with formative beauty, but Gaultier disassembled dresses and raised questions about the logic of dresses themselves.

The ball-on-disk type sliding tests with boundary lubricated steels were carried out to verify the effect of initial spacing in surface profiles on wear and scuffing. Three kinds of surface spacing, which are closely related with initial surface micro-cracks on sliding surfaces, were produced on AISI 1045 steel surfaces using different grinding and polishing processes. Frictional forces and time to scuffing were measured, and the shape and amount of wear particles were analyzed to compare the with original surface profiles. From the tests, it was confirmed that the size of wear particles are related closely to the original spacing of the surface profile. The time to failure and amount of wear were sensitive to the surface spacing. The wider surface spacing shows much longer sliding life and smaller amount of wear than the others. Time to scuffing was increased with increasing surface pro(lie spacing. The size of wear particles increased while the wear and wear rate K were decreased with an increase in surface spacing. After the sliding tests, surface cracks of inner parts of the wear track formed due to scuffing were observed and compared among the specimens having the different surface spacing.

In this paper the ball-on-disk type sliding tests with boundary lubricated steels were carried out to verify the relation between surface profiles and wear as well as scuffing. Three kinds of surface roughness and asperity radius were produced on AISI 1045 steels using the different processes of grinding and polishing. Frictional forces and time to scuffing were measured. Also, the shape and amount of wear particles were analyzed to compare with original profiles. From the tests, it was confirmed that the size of wear particles are very related to original surface profile. The time to failures and wear amounts were sensitive to the surface spacing. The large surface spacing shows much longer sliding life and smaller wear amount than the others. Time to scuffing was increased with increasing surface profile spacing. The sire of wear particles was increased and the amount was decreased with increasing surface profile spacing. Wear volume and wear rate K were decreased with increasing surface profile spacing. And after sliding tests, surface cracks of inner parts of the wear track occurred scuffing were observed and compared the differences about each specimen having the different surface profile spacing.
