The study analyzed the characteristic of school uniform, focusing on Ewha Woman's University of Seoul, reflected present trend as well as characteristic and symbol of school and developed uniform design for advertising Ewha Woman's University. The purpose of this study is to propose uniform that can be discriminated from that of other university and increase advertisement effect with mental superiority and pride in university by trying uniform design development, which can provide school and student with satisfaction, and reflecting present trend as well as characteristic and symbol of school. The study is meaningful because it can be basic materials for various uniform designs, connecting function, symbol and trend to uniform development. The uniform for school advertisement was manufactured in a way to reflect characteristic and image of school, escape from fixed idea preferring traditional design in the past and reflect trend. It is expected that the uniform created with symbolic image of school will give high advertisement effect and improve school image by providing student with sense of coherence and discriminated feeling in various events and the meeting with other school students. Moreover, the student wearing the uniform with splendid design will feel mental superiority and have pride in school at the same time. In conclusion, the uniform reflecting trend is proper for the uniform of advertisement helper representing school as long as it can reflect characteristic and image of school. It will be also helpful for developing wider design and more splendid uniform because the study can create the motive to apply trend to other uniform that does not adopt trend.

This research is to investigate the perception and satisfaction of high school students for Saenghwal Hanbok school uniforms. With this study we will be able to provide useful information for clothing companies as well as schools which are planning to introduce Saenghwal Hanbok as a uniform. The research subjects included 446 high school students of Chungcheong and Gyeonggi areas. The results of this study are as follows: 1. Male students evaluated Saenghwal Hanbok affirmatively in terms of its activity convenience. Female students, on the other hand, thought highly of it in such aspects as modern beauty, aesthetic color, distinction, symmetry, wearability, tidiness, color harmony, color unity, decoration details, and suitability for special occasions as well as modem daily life. 2. The satisfaction with Saenghwal Hanbok as a school uniform stayed, on an average, below a mid-level. It appeared that high schools with long history showed more interest than comparatively newly-established schools. Also, students with obesity liked Saenghwal Hanbok more than normal students. 3. The students' demand for price cut was highest among other demands of Saenghwal Hanbok school uniform. In addition, almost all items including wearability, material, color, activity convenience, and patterns appeared to need more improving.

A good school uniform leads students to good behavior and have them enjoy desirable school life. Therefore a better fabric for girls' high school uniform suggested through two series of studies; first, examined the various aspects of current uniforms. Second, made a new fabric for uniform considering elasticity for activity and comfortableness, and compared its characteristics with those of the current uniforms. The results are as follows; 1 Most of students wanted uniforms considering elasticity for activity and wearing. 2. The measurement of the elasticities of the uniform materials showed that the material which was made using the elastic material was more elastic than the currently used material by 42.12% in summer material and 20.05% in winter one. 3. The analysis using the combination of the values of mechanical properties showed that the elastic material was better in the wearing, tactile senses, and drape properties than the current material, even though it was a little worse in shape-stability. 4. To compare the thermal insulation, clo values were measured. For winter uniform, the elastic material was better than the current one in keeping warm. However, This study did not find any big difference between summer uniform materials.

A reactor coolant pump (RCP) is essential for transporting coolant in the primary loop of pressurized water reactors. In the advanced passive reactor, the absence of a long pipeline between the steam generator and RCP serves as a transition section, resulting in a non-uniform flow field at the pump inlet. Therefore, the characteristics of the pump should be investigated under non-uniform flow to determine its influence on the pump. In this study, the pressure pulsation characteristics were examined in the time and frequency domains, and the sources of low-frequency and high-amplitude signals were analyzed using wavelet coherence analysis and numerical simulation. From computational fluid dynamics (CFD) results, non-uniform inflow has a great effect on the flow structures in the pump's inlet. The pressure pulsation in the pump at the rated flow increased by 78-128.7% under the non-uniform inflow condition in comparison with that observed under the uniform inflow condition. Furthermore, a low-frequency signal with a high amplitude was observed, whose energy increased significantly under non-uniform flow. The wavelet coherence and CFD analysis verified that the source of this signal was the low-frequency pulsating vortex under the steam generator.

The objective of this study is to compare and analyze middle and high school boys' and girls' uniform wearing conditions. The survey was conducted online and data were obtained from 907 middle and high school boys and girls. The results of this study are as follows. First, most boys and girls did not know their body sizes other than their height and weight. Second, when purchasing the school uniforms, over 70% of the boys and girls chose to try on the uniforms before their purchase and over 60% of the boys and girls had trouble selecting their sizes just by reading the labels. Third, both boys and girls considered the fit as the most important factor. When purchasing jackets, both middle and high school boys considered the shoulder width as most important. Middle school girls considered the jacket and sleeve length as most important, whereas high school girls considered the shoulder width, waist, and bust as most important. When purchasing skirts or slacks, waist girth was considered as most important. Fourth, boys repurchased more school uniforms than girls. Boys have outgrown their uniforms usually in the length categories, whereas girls have outgrown in the girth categories. Fifth, more girls(72.7%) modified their uniforms than the boys(56.8%). Boys usually bought bigger uniforms, modified them to fit and when they grow out of their uniforms they planned to modify their uniforms again whereas girls modified their uniforms to follow the trend. Sixth, the online shopping mall survey has revealed that both boys and girls liked the idea of 3D model that reflect their own body shapes, but they had low preference to purchase school uniforms online. Online purchase has been more attractive to the boys than to the girls, while the way of fashioning uniforms has been more attractive to the girls than to the boys.

Teenagers are fast in growth and very sensitive. They are more interested in appearance and clothing and they use it as a method of expressing themselves. Thus they show different attitudes toward clothing. This study is to survey teenagers' attitudes toward clothing, especially school uniform and to understand their psychological characteristics about clothing. The purpose of this study is to provide useful data in designing teenagers' school uniform which can serve to fulfill their clothing desire and beautiful school life. The results of this study can be summarized as follows. As of paradigm in clothing, they value individuality, economical efficiency, practicality, fashion, and conformity of clothes in the order of importance. They considered individuality value the most important. Students' preference of school uniform is not positive over all. About 60% of students support wearing uniform, and 50% like wearing uniform on the way to school. The reasons for wearing school uniform are psychological stability and economical efficiency. They think school uniform is well fitted for the student position and don't have to care about clothing if they wear school uniform. 63% of them prefer wearing famous brand but they think the price is too high. Comparing with male student, female students place more value on latest fashion and are more likely to purchase brand object than male students do. Female students have more experience in modification of school uniform than male students do. Based on the result of this study, we need to understand the students' attitudes toward school uniform and to accept demand of teenagers' idea in production of school uniform.

The response of the adolescents toward school uniform regulations according to personal character and clothing needs was studied. To carry out this experiment, questionnaires were administered to 514 students in middle and high schools in Seoul and Gyeonggi-do. The collected data were analyzed with Factor analysis(Varimax rotation), Cronbach's ${\alpha}$, Frequencies Statistics, t-test, ANOVA, and multiple regression analysis using the SPSS WIN 15.0. By surveying on actual condition of uniform regulation in school, it was found that the existing uniform regulation was unnecessarily strict and caused stress leading a negative educational effect. Based on the relationship among the degree of regulation, stress, and student attitude toward school uniform regulation, stress and negative attitude to uniform regulation increased as the degree of regulation increased, resulting in an decrease in observance behavior of students. Since the stress from the school uniform regulation can be reduced by establishing rational law, which induced voluntary conduct of student to obey, it is important for student to participate in establishment of adoptable and reasonable school uniform regulation law.

The purpose of this study was to acquire the better and more correct information on the school uniforms with which middle or high school students may be satisfied. We investigated clothing interest, school uniform satisfaction, school uniform modification behavior and the relationship anions those factors. The data were collected from 472 questionnaires of middle and high school students who lived in Gyeonggi-do and analyzed statistically. We found that adolescents felt a great interest in appearance, fashion, brand orientation of clothing, and they spent most of personal expenses in buying clothes. However, the extent of adolescents' satisfaction on school uniform was low. Especially, the satisfaction on status symbolism, fashion, washing & management, body comfort and economical efficiency of school uniform was found low. Three hundred fifty three students (74.8%) agreed to modify the school uniform for personality and in chase of fashion. Two hundred eighty four students (58.1%) needed partially and variously modified school uniform, and these modifications showed a tendency of tightness to the body. We also found that the higher adolescents' clothing interests in appearance, conformity, modesty and brand orientation were. the more satisfied adolescents were with the status symbolism and the washing & management of school uniform and the more affected the school uniform modification behaviors of students were. There were. however. no significant difference between the extent of school uniform satisfaction and the school uniform modification behavior, Another research of school uniform will be necessary in order to reduce the discrepancy between clothing needs for representing the appearance, personality and fashion in the present adolescents and those for representing the worthy and modest images of a student and pursuing the economic value through school uniform in the older generation. We suggest that students should consider these results when they choose school uniform and furthermore both the person in charge of schools and school uniform makers should refer to those when they design and make school uniform.
