The culture includes every possible objective forms created by humans and their shared aspects of ideas, feelings, and behaviors, beliefs and etc. The dress and its ornaments are part of the culture that expresses the relationships in objective ways and in formless immaterial ways. The school uniform represents significant meanings to the students in their school years, and it is the way of expressing their individuality and full filling their needs for self-presentation. Therefore, understanding and analyzing youth culture means understanding students' school uniform along with fast changing twenty first century civilization. Korea and Japan are very close nations to each other. Both Korean and Japanese girls' school uniform style were adopted western clothing style and went through many changes based on cultural differences between two countries. They are affected by different peculiarities between two nations and youth cultures from different cities. Therefore, this research is on analyzing how different visual values of girl's high school uniforms in Seoul and Tokyo and understanding youth cultures through macro-analysis. The youth cultures in Korea and Japan are mostly similar but there is special development on animation in Japan and possibly can find many styles of girl's high school uniform. Both nations are varying to be opened to sexual culture of adolescents but Japan is more uninhibited than Korea. In Japan, sailor-uniform can be found in fetish way in public culture. On one hand, because of most private girl's high schools in Tokyo takes an entrance examination, top-ranking students are very proud of their school uniforms and even students from other public high schools get private high school uniforms to attend school festival. This analysis showed that private girl's high school uniform in Seoul appealed as slim fitted silhouette which is close to modem woman's suit style while in Tokyo appealed as boxy style matched with short pleated skirt or sailor-uniform style. Comparing that to school uniform photos taken on the street, we can find that alikeness or more extreme styles as examples. These are influenced by different youth cultures in Seoul and Tokyo and cultural differences stands for different aesthetic norm being accepted or rejected.

The purpose of this study was to develop middle school girl's' school uniform sizing system according to their body types. The data collected with anthropometric measurements from 390 middle school girls aged 12-15 years old was analyzed using t-test, ANOVA, factor analysis and cluster analysis. A new sizing system was developed in accordance with each of the 2 body-type clusters. The analysis of two-way distribution of 'height-bust girth' and 'height-waist girth' was conducted for the girls of the first grade, which is the time when they purchase their school uniforms. The interval of sizing system was defined in consideration with the most efficient distribution of the body sizes utilizing Loss Function. This study also provided Reference-Sizes and Growth-Allowance Measures for each sizing system to help pattern drafting and clothing construction of the uniform manufacturers. The cover ratio of sizing system proposed by this study was higher when compared with that of the National Agency for Technology and Quality and uniform manufacturing companies, Thus, the result of this study is expected to make up the current sizing system of the school uniform.

The purpose of this study is to investigate the present states and preferences for a type of campus wear, the differences between the life-style variables and clothing behavior among school uniform students and non-uniform students, to explore variabels of the purchasing tendency in clothes of boys' and girls' high school students. The questionnaires were administered to samples of four boys' and girls' high schools respectively in Kwangju. The data from 522 respondants were analyzed in using Frequency and T-test. The results were as follows: 1. Most of schools are likely to take a school uniform system in the near future but students do not have favorable attitude against the system. 2. There were partly significant differences between the clothing behavior variables (boys : psychological dependence, comfort and atmosphere of the store, girls : downtown shopping) among school uniform students and non-uniform students. 3. There were partly significant differences between life-style variables(boys : leadership and social attitude, advertisement confidence, girls : price consciousness) among school uniform students and non-uniform students. 4. About 80% of the subject group planned their clothing purchase in advance, and their parents and friends influenced on clothing buying behaviors more then other fashion information sources, however, for the boy students the atmosphere of the store is most affecting variables. The store in which the subject group purchased clothing most frequently was a specialty fashion store. In clothing selection, aesthetic factors were showen as important factor and the most affecting mass media is TV.

The purpose of this study was to provide information on how to improve both the satisfaction and the current sizing system for the school uniform focused on middle and high school girls' students. For the satisfaction of their school uniform, there were statistical significance by the academic year in jacket design, blouse color, and skirt design in the case of middle school girls'. On the other hand, high school girls' evaluation of school uniform was significantly different in jacket color, jacket design, blouse color, textile of blouse, skirt color, and skirt design by the academic year. For the assessment of wearing motion, there was no significant difference by the grade in both middle school and high school girls'. However, it was shown more frequency of discomfort than that of comfort. For the evaluation of sizing fitness, the breadth of sleeve in jacket and the width of blouse were statistical significance in middle school girls' by the grade while the width of jacket, he breadth of sleeve in jacket, the length of blouse, the width of blouse and length of sleeve in blouse were different in high school students by the grade.

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 purpose of this thesis is presenting desirable design of uniform which could reflect high school girls' demands with the researches on their consciousness of fashion and actual state of uniforms. Methods to accomplish this research include first, examinationson characteristics of high school girls and their consciousness of fashion with relevant articles, second, interviews with designers from major domestic uniform brands - ELITE, IVY, SMART - and third, analysis on related internet sites. Practical researches are followed by design analysis and proposal of improvement on high school girls' uniform, accompanied by collection of photographs from field studies, major uniform brands' shops and uniform related internet sites. Korean high school girls in the digital era are able to express themselves in each different fashion with own individuality, preference or intention, as they are particularly interested in clothes or their appearances. Their consciousness of fashion became visible in a shape of negative attitude and dissatisfaction with uniforms due to its out-of-date design, lack of features and inconvenience in action. Besides more than half of high school girls already experienced reforming it for better looks. As a result of current analysis on references of uniform designs, various levels of refinement were noticed even in uniform of similar details, design, fabric textile and color due to differences on size & length of jacket collar, dart, cutting line, size of details, decorative line, easiness in fit, length of clothes, and etc. To provide students of more refined and desired designs which reflect their demands, current uniforms are to begin acquiring delicate changes with present vogue and feature such as size of details, silhouette, cutting line, decorative line and etc. In addition newly designed uniforms are to present desirable design with image of refinement and neat as they actively comprehend students' needs within its symbolic, functional, economic and aesthetic characteristics by nature.
