The purpose of this study was to investigate the actual wearing conditions and the preferences of knit wear school uniforms. The subjects were 480 high school girls from 6 high schools placed in Daejeon. The method of study is a survey consisted of actual wearing conditions questionnaires, preferences questionnaires, and demographic attribution. Data was analyzed by frequency, variance, crosstabs, and correlation analysis using SPSS 12.0 program. The results of study are as follows. First, high school girls over 90% wearing knit wear school uniforms were satisfied with current knit wear school uniforms(navy color, V-neck, and wool mixed). Second, high school girls preferred 100% cotton material and black/white/gray color group. The style of knit wear school uniforms was most preferred monochrome cardigan with cable pattern. High school girls wanted to show neat image by knit wear school uniforms and to diversify the style of them. Third, the differences of preferences between groups, they were wearing knit wear school uniforms(A group) or not(B group), were about pattern and improvement. A group preferred school mark pattern, and wanted to improve the quality and after service. B group preferred monochrome cable pattern, and wanted to diversify the style. Both groups wanted to wear knit wear school uniforms because knit wear was 'warm' and 'comfort'. Consequently, knit wear school uniforms will help high school girls express individuality and beauty.

The purpose of the present study was to analyze the acceptance level of forecasted information of casual wear in tate 1990s in Korea and the way of utilizing fashion trends information by casual wear industries. The Present study was implemented by content analysis and descriptive survey using questionnaire and interview. Trends information in fashion journals published by fashion institute and articles in daily newspapers were analyzed in terms of fashion image, color, fabric, and silhouette. The data collected from questionnaire and interview with 113 fashion specialists were analyzed through frequency, percentage. The results indicated that among the forecasted information regarding fashion image, romantic and feminine images showed a high level of acceptance to national brand women's casual wear in the late 1990s, while mannish image showed a low level of acceptance. For men's casual wear in the same time period, androgynous trends appeared most frequently, not only in forecasted information, but also in actual trend. it was forecasted that yellow, white, and gray would be in trend and those colors appeared frequently in actual trend. On the other hand pastel tone appeared much more frequently than forecasted. Natural, thin - transparent (S/S) and stretch fabrics (F/W) were in actual trend as it was forecasted. Fit and Pare (woman), and long and slim (man) silhouettes were in actual trend as if was forecasted, but barrel silhouette appeared only in forecasted information. Most of the information forecasting fashion trends for next season were applied to the product planning of the season, right after the information comes out.

A new type of a fretting wear tester has been designed and developed in order to simulate the actual vibration behavior of a nuclear fuel rod for springs/dimples in room temperature. When considering the actual contact condition between fuel rod and spring/dimple, if fretting wear progress due to the flow-induced vibration (FIV) under a specific normal load exerted on the fuel rod by the elastic deformation of the spring, the contacting force between the fuel rod and dimple that were located in the opposite side should be decreased. Consequently, the evaluation of developed spacer grids against fretting wear damage should be performed with the results of a cell unit experiments because the contacting force is one of the most important variables that influence to the fretting wear mechanism. Therefore, it is necessary to develop a new type of fretting test rig in order to simulate the actual contact condition. In this paper, the development procedure of a new fretting wear tester and its performance were discussed in detail.

The thermal fatigue and wear properties of high speed steel roll which was recently developed were investigated by observing microstructure, by measuring mechanical and physical properties, by conducting thermal fatigue testing, and by measuring the amount of wear in actual mill. High speed steel roll had better thermal fatigue testing, and by measuring the amount of wear in actual mill. High speed steel roll had better thermal fatigue life than high chromium iron roll, which was due to lower carbide content, higher strength, and higher thermal conductivity. The amount of wear of high speed steel roll was nearly the same as that of high chromium iron roll in the first finishing stand, which was due to the oxide formation on the roll surface. However, in the third finishing stand, the wear resistance of high speed steel roll was 2~3 times as good as that of high chromium iron roll because the former had higher hardness at high temperature.

This study looked into the characteristics of participants in dance sports, which is being positioned to be one of everyday athletic activities among people, and investigated the actual purchasing of dance sports wear with the subjects of its participants as a preceding study for the development of dance sports wear to consider their characteristics. The questionnaire method was used, and descriptive and crosstabulation analysis was conducted with a spss 12.0. The findings are as follows. 1. As the results that examine general characteristics of dance sports participants, the number of those in their 20's was the largest, while the number of women was larger than that of men. Regarding the practicing period, those of one year or longer up to 4 years occupied the largest proportion, and the rate of Latin American dance participants was larger than that of modern dance ones. 2. As to the actual purchasing of dance sports wear, the purchase motivations were found to be in the 'contest participation' for teenagers and those in their 20's, while those in their 40's or over purchased their wear for the purposes of 'following the fashion' or 'club gatherings.' As for the sources of information at the time of purchase, teenagers relied on internet and those of 20's or over got the information through the persons nearby. As their ages got higher, the ready-made sports wear was preferred, while as their practicing periods got longer modern dance participants purchased the sports wear of higher prices. Participants in their 30's and those practicing 7 years or longer possessed a comparatively larger number of dance sports wear and they considered importantly of designs and fit at the time of purchase. Therefore, the development of dance sports wear designs should be made to accord with the participants' age groups so that they might be sensitive to the fashion and clearly represent their personality for the junior group and durable enough to last long for the senior group.

The purpose of this study was to compare ideal clothing and actual clothing behavior between Korean and Japanese college students. 185 Korean students and 91 Japanese students were used into data analysis from October to December. 2000. The age range was 18 to 28 years. The results were as followed. 1) Japanese students wanted to wear fitted clothing styles with revealing the body, while Koreans wanted to wear not only fitted styles but also relaxed and coved body styles. 2) Korean students wore more loose styles and fitted upper styles and pants than Japanese students. On the other hand, Japanese students wore fitted clothing styles and skirt. 3) Japanese students showed higher correlation between ideal clothing styles and actual clothing styles than Koreans. This means that although Koreans want to wear ideal styles, they don't wear those styles much. 4) Overweight students tended to avoid wearing fitted and revealed body styles, pursuing more loose and coved body styles. This tendency showed stronger to Koreans than Japanese students.

As for the purposes of the research: First, on the wearers of snowboard wear on the market, I intend to investigate contents related with purchase, price, brand, style, etc., and grasp requirements and complaints. Second, I intend to know the evaluations of users according to itemized questions on the snowboard wear on the market. Third, I like to provide basic materials by investigating itemized requirements for the development of snowboard wear. On the male & female snowboarders on a skiing ground, I carried out a preliminary investigation in December, 2001, and a main investigation from January to February, 2002. The results are as follows: 1. Many of them purchased imported quality goods, and the rate purchase was high between 20～25 year. Loose two-piece suits of different colors were preferred. The most uncomfortable part proved to be a neck part. 2. The degree of general satisfaction with the snowboard wear on the market was 4.60. And in terms of itemized evaluation, dissatisfaction was found in Clothing construction, facility of laundry and handling, price and brand rather than in style, fiber composition and tactile sensation. 3. In the investigation of the requirements in case of snowboard wear development, the most common requirement was the facility of action. I believe this should be met by study on the choice of pertinent margin and the pattern development.

Wear and rolling contact fatigue (RCF) defects are most important causes of rail damage, and often interaction competitive at present railway track. Head check is one of rolling contact fatigue (RCF) defects, and generally occurs in mild circular curves and transition curves that are set at both ends of sharp circular curves. Wear tends to limit the crack growth of head checks by removing the material from the RCF surface. In order to clarify the conditions of the occurrence and growth of head checks, the authors measured the interacting forces between wheels and rails and the angle of attack of wheelset, and carried out contact analyses using the actual profile data of wheels and rails. The effects of the lateral force, the contact geometry, and the wear rate at rail gauge comer on the formation of head checks were also analyzed by using the worn profiles of actual wheels and rails and the data obtained by a track inspection car. Some specific range of wear rate at the gauge comer was identified as having close relation with occurrence of head checks.
