Korean sports fashion began after 1990. after 1960, using vinyl, leather, plastic ＆ metal material, Yve st. Laurent, Pierre Cardin, Andre Courrges, they lead sportive look. Head of 20th century, fashion was lead by haute­couture, after 60s. It was changed to pret­a poter. Now it can be called of american casual ＆ sports fashion. This study would be a view of modem fashion trend and process of visualization in the future. I studied in reproduction of view ＆ age of hyper media with visual circumstance ＆ artistic background and mordern fashion trend ＆ sports fashion image in korea. In conclusion, sports fashion image as visualizing aesthetic concept of modern fashion be defined as technology for man, for instance comfort, function, flexibility, simplicity and minimalism. Specically, Sports fashion was began satisfied for function after 90s, we can see variety of easy wear, hip-hop casual, entertainment sports wear, new street sports wear, luxury sports wear.

Acoustic emission(AE) signal has been widely utilized to monitor the interaction at the head/disk interface. In this work the relationship between the AE signal and the state of contact between the slider and the disk is presented. Results of the FFT analyses of the AE signal could be used to better understand the interfacial interaction. Also, it was found that wear particles affect the AE signal. Therefore, the signal can be used to monitor the wear particle presence at the interface.

In this work the surface damage mechanism of hard disk was investigated. Experiments were peformed to simulate the contact during start and stop. Evidence of significant surface damage appeared after 20,000 cycles. It was found that despite higher hardness, the slider showed more signs of damage than the disk. Optical microscopy showed that the surface was damaged by abrasive action as well as adhesion of wear debris.

Ceramic femoral heads in the total hip replacement have been developed to reduce the polyethylene liner wear. Alumina and zirconia (3Y-TZP) are using in clinical application worldwide and there are many good test reports. However, alumina has a risk of catastrophic failure, and zirconia has the low temperature degradation in spite of enhanced fracture toughness. Recently, novel zirconia/alumina composite having low temperature degradation-free character and high fracture tough . was developed and it leads the lower wear 3f polyethylene than alumina and zirconia. In the present study, in order to optimise the microstructure of low temperature degradation (LTD)-free zirconia/alumina composite for the best wear resistance of polyethylene, various compositions of (LTD)-free zirconia/alumina composites were fabricated, and the sliding wear of UHMWPE against these novel composites were examined and compared with that against alumina and zirconia ceramics used for total hip joint heads.

In this paper We propose one computer interface device for handicapped people. Input signals of the interface device are movements of eyeballs and head of handicapped. The movements of the eyeballs and head are detected by an image processing system. One feature of our system is that the operator is not obliged to wear any burdensome device like glasses and a helmet. The sensing performance of the image processing of the eyeballs and head is evaluated through experiments. Experimental results reveal the applicability of our system.

Loading/Unloading(L/UL) mechanism has been considered to be an alternative to contact start-stop(CSS) mechanism which eliminates stiction and wear associated with frequent start and stop process. It has other advantages including increased areal density due to lower flying height, reduced power consumption, and improved shock resistance. In order for L/UL to be Implemented in Near-field recording system properly, dynamics of optical flying head must be understood and optimized. In this paper the dynamic characteristics during loading process is analyzed numerically to investigate the effect of design parameters such as loading speed. slider shape, and initia conditions on the dynamic reponses of flying head..

Head Disk Interface (HDI) in a Hard Disk Drive (HDD) has decreased to achieve high areal density. Thus, the contact between a slider and a disk becomes more important. The contact between the slider and the disk can cause severe wear and damage of both the slider and the disk. Especially, Touch Down (TD) that the contact occurs continuously and repeatedly is extremely dangerous. Therefore, it is necessary to analyze the unstable bouncing vibration of the slider in head-disk interface. In this paper, we investigate the characteristic and causes of the Touch Down.

The purpose of this study was to examine the cases of the family head's costume culture and to apply them to field experience education of adolescent's home economics subject. To examine the family head's costume culture, women in the family head in the Hampyeong area, Jeollanam-do were selected and interviewed. The focus of examining the family head's costume culture was on the life story of the family head, the reason to wear or possess such costume, and a motive of making. The findings of the head family's costume culture suggests that the head family of the Mos of Hampyeong had unique shroud making and custom. Also it was found that the eldest daughters-in-law of the Lees of Hampyeong have horizontally exchanged the information of the family head's costume with village women of the same family. They have initiated their costume culture directly through their daughters and it had the great influence on after-ages. The learning program for youth to experience the head family's costume culture consisted of four subjects:(l)Educating the family head's traditional living culture including etiquette training, (2)head family village walk, (3)experiencing the family head's clothes life including natural dyeing and sewing, and (4)a field trip of Hampyeong Local Life Culture Museum. For a model experience of the family head's costume life culture, three families with middle and high schoolers participated in 8- hour experience learning program. To examine the effect of learning program to experience the family head's costume culture, youth and their parents who participated in the program were asked open-ended questions, which included the content validity of experience learning, impressive experience, model experience level(difficulty), and expected effect after a model experience. As a result, their responses were found positive.

At the moment, the section insulators for different phases used for over head contact wire system has been all imported since its first application. However, because the section insulators need frequent maintenance and replacement due to the wear by the friction with pantograph and the contamination, which causes its life shorter than as expected, it is required to develop the insulation material with better wear-resistance characteristics and contamination-resistance characteristics. In this thesis, the author developed the section insulator which adopts Teflon tube insulation material which is composed of the Teflon material with the excellent electrical characteristics and wear-resistance characteristics for a longer expected life than that made of conventional FRP.
