Hydrogen peroxide used for hair bleaching and permanent wave as oxidants in cosmetics. So that, in this study, the improvement effect of hair bleaching was investigated by electrolyzed acid and alkalic water treatment under different hydrogen peroxide condition. In thereslut, it was found that in hair treated in 10-minutes bleaching, the hair pre-treated with electrolyzed alkalic water had high brightness,in hair treated in 15-minute bleaching, the brightness of the hair pre/post-treated with electrolyzed water was the highest, and hair treatedin 10-minute decoloring agent after pretreatment with electrolyzed alkalic water had higher brightness than that of hair treated in 15-minute bleaching. The pieces with thick hair and higher tensile strength were the pieces of hair treated with decoloring agent for 10minutes and the ones pre/post-treated with electrolyzed water; it was indicated that the hair which had long reaction time for decoloringagent and the hair pre-treated with electrolyzed alkalic water became thinner, and their tensile strength weakened. As the degree of waters welling and alkali solubility were the lowest in the hair pre/post-treated with electrolyzed water, followed by the hair treated with decoloring agent and the hair treated with electrolyzed alkalic water, it was observed that reaction time for decoloring agent and the treatments with electrolyzed alkalic and acidic water had effect on the damage of hair. The cuticle of the hair pre-treated withelectrolyzed alkalic water was thick, the thickness of cuticles of hair treated with decoloring agent and the one post-treated with electrolyzed acidic water were found to be thin, and the morphological change in the cuticles and their damages were observed to bealmost same. Thus, it was proved that pre/post-treatment of electrolyzed water enhanced the bleaching effect of hydrogen peroxide and minimized damage of hair.

The purpose of this study is to examine the effect of permanent wave formation and minimization of hair damage. The virgin hair as hair sample was divided in 6 hair pieces (Control, PW-1, 2, 3, 4, 5). 5 The formation of curl, S-wave and change of the physicochemicalproperties were observed in permanent waving hair pieces. Pre-treatment with alkaline EW (PW-4 and PW-5) was higher in the S-waveformation rate, the most commonly used thioglycolic acid with sodium bromate treatment (PW-1) was the lowest in the permanent waving hair pieces. Thickness and tensile strength of hair shafts in pre- and post-treatment with EW (PW-5) were the most high and thick. In contrast, the pre-treatment with alkaline EW (PW-4) was the lowest in two indicators. The water swelling and alkali solubility in pre- and post-treatment with EW (PW-5) were the lowest in all of permanent waving hairs, and alkaline EW pre-treatment hair was higher than the other permanent waving hairs. In conclusion, only the pre-treatment with alkaline EW may be very useful for the virgin hair and pre- and post treatment with EW for the damaged hair.

In this study, dissimilar friction welding were produced using 15mm diameter solid bar in chrome molybedenum steel(SCM430) to carbon steel(SM45C) to investigate their mechanical properties and the relationship between the weld parameters and the nondestructive coefficients. The main friction welding parameters were selected to endure good quality welds on the basis of visual examination, tensile tests, Vickers hardness surveys of the bond of area and heat affected zone. The specimens were tested as-welded and post weld heat treated(PWHT). The tensile strength of the friction welded steel bars was increased up to 100 of the SM45C base metal under the condition of all heating time. The toughness of PWHT specimens is higher than as-welded.

Generally, it is said that the higher a country's economic development and culture, the more demands for upstyle that is definite manufaturing's methord of hairstyle. The thesis compared and analyzed change of manufacturing’s methord by hairstyle, its modeling effect and change factor of modeling design of hair style. Given the result from manufaturing's methord of hairstyle, the thesis intended to hair style changes are expected to used for basic data for development of us techniques and designs and are believed to need more following studies.

Hairs have a number of functions including thermoregulation, collecting sensory information, protection against environmental trauma, social communication and mimicry. The hair is altered and changed such as weakness of tensile strength, alopecia and canities by physical and environmental factors. In this study, the physicochemical properties and morphological change of in altered hairs were investigated in 24 spenders of adulthood and elderly. Thickness, tensile strength, water swelling and alkali solubility, breadth and thickenss of hair cuticle were measured and morphological change of cuticle and cortex were observed. In the result, thickness and tensile strength of hair as aging indicator decreased significantly in elderly men and women in contrast to adulthood (p<0.05), and both parameters were higher in men than in women of adulthood and elderly. Breadth and stepping of cuticle decreased in elderly men and women in contrast to adulthood. But water swelling and alkali solubility as hair damage indicators increased in elderly men but not women. More damaged cuticles and diffuse melanin granules appeared in elderly than in adulthood by SEM and TEM observation. In conclusion, aging induced to change of physicochemical properties and morphology, and decreased hair thickness in elderly men and women may be not decreased thickness of cuticles but loss of cuticle layers.

본 연구는 청소년 학교적응의 지표로 사용될 수 있는 삶의 만족, 진로결정자기효능감, 우울, 학업성적에 따른 군집의 특성을 파악하고, 5요인 성격 특성이 유의하게 군집을 판별해 주는지를 살펴보았다. 이를 위해 서울, 경기 지역 고등학생 총 245명(남자 175명, 여자 70명)을 대상으로 군집분석을 실시한 결과 3개 군집으로 구분되었다. 5요인 성격 특성이 각 군집을 판별하는 상대적 영향력을 알아보기 위하여 판별분석을 실시하였다. 그 결과, 두 개의 판별함수가 모두 통계적으로 유의미하였으며 특히, 5요인 중 신경증, 개방성, 성실성이 집단을 판별하는데 가장 좋은 판별 변인이었다. 전체적으로 적중률(hit ratio)은 56.1%이었고, 특히 군집3에 대한 적중률은 64.7%이었다. 마지막으로 청소년의 학교 적응을 예측하고 판별하는 도구로서 간편형 5요인 성격척도의 유용성에 대해 논의하였다. The purpose of this study was to investigate the clustering and Big Five Personality domains in discriminating groups by level of school-related adjustment, as experienced by Korea high school students. Data was collected by administering 4 questionnaires (the short version of BFI, Satisfaction with life, Career Decision-Making Self-Efficacy, Depression) to the participants who were 245 high school students in Seoul and Gyeong-gi province. For the purposes of the data analysis, both Stepwise Discriminant analysis and Cluster analysis was employed. The results of the study are as follows. Firstly, the subjects were grouped into 3 clusters according to their level of school-related adjustment. Secondly, Neuroticism, Openness, Conscientiousness within the Big Five Personality domains were seen to be significant variables when it came to discriminating the groups. These findings indicated that the short version of the BFI may be useful in screening for school maladjustment in adolescents.

In modern society, the development of fractal geometry has played a critical role in creating a beautiful, convenient, and abundant human life by having a significant effect on many design fields. In fact, it is a genre of practical arts, which has a significant effect on the development of civilization. Influenced by modernism, hairstyling now seeks a new paradigm, seeing its limitations. In foreign countries, there have been educational guidance plans on the creation of new hairstyles using fractal geometrical patterns, in which art and science are combined. In fact, various fractal geometrical designs have been created using computer technology. Even though fractal geometry is essential to stay competitive in a new globalized cosmetology market,there have been few studies on fractal geometry-based hairstyles in South Korea. Therefore, this study attempted to propose an educational guidance plan to create hairstyles that can satisfy diverse consumer needs and demands in the new hairstyling market by guiding education on potential and applicability in fractal geometry-based creative hairstyling. Considering that it is urgent for cosmetology-related departments in college to cover formative education on hairstyling, therefore, this study aims to give students an opportunity to develop their potential and become a competent hairstylist in the world with fractal geometry-based formative educational courses.
