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.

본 연구는 여고생들의 연예인 모방유형에 따라 외모관리행동 즉, 교복 변형행동, 헤어스타일 관리행동, 화장 관리행동 등에 미치는 영향을 조사하였다. 이를 위해 전북에 거주하는 여자고등학생 379명의 데이터가 사용되었고 신뢰도분석, 요인분석, 군집분석, 일원배치분산분석, 교차분석을 사용하여 분석하였다. 본 연구를 통하여 전북지역 여고생들은 연예인 모방유형에 따라 적극적 수행형, 심리적 욕구형, 연예인 호감형으로 분류되었다. 연예인 모방행동과 모방욕구의 평균이 가장 높았던 적극적 수행형 여고생들은 교복변형 경험이 가장 높았으며, 드라마속 연예인이 입고 나오는 교복스타일을 따라해 보고 싶어하고, 연예인 교복스타일로 교복을 변형한 경험이 있는 등 연예인 교복스타일에 많은 영향을 받았다. 또한 최신 유행헤어스타일을 인식하고 연예인의 헤어스타일을 선호하는 등 헤어스타일 관리행동에 더 적극적이었다. 그리고 매일 기초화장을 하고, 화장법을 배우고 싶어하는 등 화장 관리행동에 더 적극적임을 알 수 있었다. 반면 연예인 모방 행동과 모방욕구의 평균이 가장 낮았던 연예인 호감형 여고생들은 교복변형행동, 헤어스타일 관리행동, 화장 관리행동 등에 소극적임을 알 수 있었다. 따라서 청소년에게 바람직한 매스미디어에 관한 체계적인 교육을 실시하고, 교사들은 청소년들에게 합리적인 모방활동을 할 수 있도록 교육한다면 의생활지도에 있어서 효율적인 교육성과를 거둘 수 있을 것으로 보인다.

본 연구에서는 여고생들의 라이프스타일과 교복변형행동의 관련성이 있는지 알아보고 이를 토대로 여고생들의 올바른 교복착용을 위한 의생활지도의 기초자료를 제공하고자 하였다. 이를 위해 광주광역시 소재의 인문계, 전문계 고등학교 6개교 1, 2학년 학생 602명의 여고생을 대상으로 설문조사를 하였으며, 설문 자료의 분석은 SPSS WIN 12.0(Kr)을 사용하여 요인분석, K-평균 군집분석, 일원배치 분산분석(one-way ANOVA)을 실행하였다. 그 결과를 요약하면 다음과 같다. 본 연구에서는 여고생들의 라이프스타일에 따른 교복변형행동의 차이를 살펴보았으며 라이프스타일 유형간의 차이가 유의하게 크지는 않았다. 대부분의 여고생들은 교복변형을 찬성하고 있어 먼저 일반적 의복행동으로 이해되었으며 다음으로 라이프스타일의 영향을 받고 있었는데 디지털의존스타일이 다른 라이프스타일 유형과 다른 경향이 있었다. 따라서 학생문화의 하나로 자리 잡고 있는 학생들의 교복변형에 대해 정해진 규율에 맞춰 엄격히 단속하기보다 일정한 범위를 두어 개성을 표현하게하거나 속옷을 갖추어 착용하게 지도하는 것이 바람직하지 않을까 생각된다. 물론 교복의 기성복화에 따른 유행의 반영은 받아들이더라도 신체가 드러나서 부정적인 이미지를 주는 경우라면 적극적인 생활지도가 필요하리라고 생각된다.

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.
