There are many students who modify their uniforms and wear fashion accessories to pursue their individualities. The objectives of this research were to identify school uniform modification and fashion accessory wearing behavior of high school students. The results were as follows; 1. High school students considered that the uniform was desirable because the uniform showed identity best, but many students complained that the uniform was uncomfortable in activity. The most accessory used for the uniform was the cellular phone handle. 2. The uniform modification behavior was highly distinguishable at the coeducational school, the vocational school, and the art or physical school. They modified their uniform to pursuit slim and individuality. The uniform modification was for the beauty aspect more rather than practical aspect of uniform, and was proportional to the degree of the appearance, and in case of pants, the length and width of the pants showed increasing trend compared to the past. They considered accessory wearing as a compensational expression of the most of students who were not actively behaving on the uniform modification.

The purpose of this study was conducted to improve middle and high school students' satisfaction on their uniforms and to provide basic information for their better size systems. This study analyzed the purchasing and modification behavior, fitting evaluation, and size decision aspect of students. This study was surveyed middle and high schools students in Daegu City. The collected data were analyzed by frequency analysis, percentage, t-test, chisquare test. The results of this study are as follows; 61.3% of the students interviewed have experienced to modify their uniforms. Since the unfittable size and non-fashionable design caused the students to modify their uniforms, it seems necessary to set up the various uniform sizes, as well as figuring out its aesthetic characteristic. Between middle school and high school students, and students with a uniform modification and students without a uniform modification, there were partially differences in fitting evaluation, and size decision.

The purpose of this study is to classify students' attitudes towards uniform modification and analyze their subjective experience regarding appearance, and body satisfaction. Questionnaires were administered to 369 middle and high school girls living in Deagu Metropolitan City. Frequency, factor analysis, reliability analysis, correlation analysis, ${\chi}^2$-test, and t-test are all used for data analysis. Our findings are as follows. Two hundred thirty students (62.3%) agreed to modify their school uniforms to express their personalities and follow fashion trends. Motives for uniform modification had to do with social life, physical attractiveness, and practicality. Attitudes toward appearance are found to be shaped by appearance internalization, active management of appearance, appearance needs, social recognition, and conformity. The motives for uniform modification reveal a significant correlation with attitudes toward appearance. Uniform modification satisfaction differed depending on sub-variables of attitude toward appearance(active management of appearance, personalized appearance needs, social recognition, and body satisfaction, such as satisfaction with height and BMI). There was a significant difference in expression of intention for future plastic surgery depending on body image.

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.

This paper examines the effect of star-entertainer imitation on female high school students in terms of their appearance management activities such as school uniform modification behaviors, hair style care behaviors, and make-up behaviors. For this research, data of 379 female high school students living in Jeollabuk-do was analyzed through reliability analysis, factorial analysis, cluster analysis, one-way analysis of variance, and cross-tabulation analysis. In the research, based on the type of star-entertainer imitation, the female high school students were divided into three categories: active followers, psychological followers, and passive followers. The research showed that active followers, who exhibited imitation behavior most frequently and had the highest imitation desire, were most frequently involved in school uniform modification. Inclined to imitate the school uniform styles of star-entertainers in soap operas, they modified their school uniforms. The active followers were also enthusiastic about hair care, were well aware of trendy hair styles, and demonstrated a fondness for star-entertainer hair styles. In addition, they were actively involved in make-up activities. They put on basic make-up everyday and exhibited a desire to learn about make-up styles. However, passive followers, who showed the least frequent imitation behavior and the lowest imitation desire, were not as keenly involved in school uniform modification behaviors, hair style care behaviors, or make-up behaviors. The study concludes that by providing teenagers with systematic education on desirable mass media and educating them on proper behavior, an effective educational tool for guidance on clothing habits can be derived.

This study was intended to examine the relationship between lifestyle and school uniform design modification in high school girls and provide basic data for guidance in the wearing of school uniform. The subjects of this study were 585 girls who were in the first and second grades of high schools throughout Gwangju. This study was executed using a questionnaire. The data from this study was processed using SPSS WIN 12.0(Kr). The results were as follows; This study hypothesized that the perception and attitude on school uniform modification would be significantly difference depending on lifestyles in high school girls. The significant differences appeared in a few items. So the results suggested that school uniform modification was a common that appeared in most high school girls. However it was affected by their lifestyle. specifically, a digital-dependence lifestyle group has a few different perceptions and attitudes on school uniform modification than the others. In other words, school uniform modification in high school girls who spend their most time in school is a general and universal clothing behavior by psychological factors rather than the effect of lifestyle. It is considered that rules concerning school uniform modification should allow students to express their individuality within certain limits. Teachers should instruct students to wear appropriate underwear rather than keep students under control with a fixed set of rules. If High school girls have a negative body image as a result of their exposed body, they should receive active educational guidance.

In most seismic codes such as the Uniform Building Code(UBC), the response modification factor(or the force reduction factor)is used to reflect the capability of a structure in dissipating energy through inelastic behavior. The response modification factor is assigned according to structural system type. Ductile systems such as special moment-resisting steel frames are assigned larger values of the response modification factor, and are consequently designed for smaller seismic design forces. Therefore, structural damage may occur during a severe earthquake. To ensure safety of the structures, the suitability of the response modification factor used in aseismic design procedures shall be evaluated. The object of this study is to develop a method for the evaluating of the response modification factor. The validity of the evaluating method has been examined for several cases of different structures and different earthquake excitations.

Pinching is an important property of reinforced concrete member which characterizes its cyclic behavior. In the present study, numerical studies were performed to investigate the characteristics and mechanisms of pinching behavior and the energy dissipation capacity of flexure-dominated reinforced concrete members. By analyzing existing experimental studies and numerical results, it was found that energy dissipation capacity of a member is directly related to energy dissipated by re-bars rather than concrete that is a brittle material, and that it is not related to magnitude of axial compressive force applied to the member. Therefore, for a member with specific arrangement and amount of re-bars, the energy dissipation capacity remains uniform regardless of the flexural strength that is changed by the magnitude of axial force applied. Due to the uniformness of energy dissipation capacity pinching appears in axial compression member. The flexural pinching that is not related to shear force becomes conspicuous as the flexural strength increases relatively to the uniform energy dissipation capacity. Based on the findings, a practical method for estimating energy dissipation capacity and damping modification factor was developed and verified with existing experiments.

The purpose of this study was to investigate students' satisfaction with, perceived ease of movement of, and perceived fit of high school girls' uniforms according to the uniform design. "P" high school, with a one-piece dress-type uniform, and "H" high school, with a two-piece type uniform, were selected for this study. Sixty-five female students from each school participated in the study. The questionnaire was composed of 21 questions about the school uniforms' purchase behavior, design, fit, ease of movement, and modification and participants' demographic information. Students from both schools were generally satisfied with the uniform design. However, in the open-ended response section, many "P" high school students responded that the fact that the one-piece dress pulled up when sitting or raising the hand made it uncomfortable. On the other hand, "H" high school students responded that the skirt was uncomfortable, because it left the body or underwear exposed when the wind blew due to the many pleats in the skirt. In the assessment of the ease of movement, "P" high school students were more likely to describe the uniform as uncomfortable than "H" high school students. Many students responded that they modified their school uniforms, and the length of the skirt and one-piece dress was the main part that was modified. This study suggests that growing female high school students are unsatisfied with the school uniforms' design and fit. Additionally, the perceived fit and satisfaction levels depend on the uniform design.

Aluminum alloys have poor corrosion resistance compared to the pure aluminum due to the additive elements. Thus, anodizing technology artificially generating thick oxide films are widely applied nowadays in order to improve corrosion resistance. Anodizing is one of the surface modification techniques, which is commercially applicable to a large surface at a low price. However, most studies up to now have focused on its commercialization with hardly any research on the assessment and improvement of the physical characteristics of the anodized films. Therefore, this study aims to select the optimum temperature of sulfuric electrolyte to perform excellent corrosion resistance in the harsh marine environment through electrochemical experiment in the sea water upon generating porous films by variating the temperatures of sulfuric electrolyte. To fabricate uniform porous film of 5083 aluminum alloy, we conducted electro-polishing under the 25 V at $5^{\circ}C$ condition for three minutes using mixed solution of ethanol (95 %) and perchloric (70 %) acid with volume ratio of 4:1. Afterward, the first step surface modification was performed using sulfuric acid as an electrolyte where the electrolyte concentration was maintained at 10 vol.% by using a jacketed beaker. For anode, 5083 aluminum alloy with thickness of 5 mm and size of $2cm{\times}2cm$ was used, while platinum electrode was used for cathode. The distance between the two was maintained at 3 cm. Afterward, the irregular oxide film that was created in the first step surface modification was removed. For the second step surface modification process (identical to the step 1), etching was performed using mixture of chromic acid (1.8 wt.%) and phosphoric acid (6 wt.%) at $60^{\circ}C$ temperature for 30 minutes. Anodic polarization test was performed at scan rate of 2 mV/s up to +3.0 V vs open circuit potential in natural seawater. Surface morphology was compared using 3D analysis microscope to observe the damage behavior. As a result, the case of surface modification presented a significantly lower corrosion current density than that without modification, indicating excellent corrosion resistance.
