Hair toners containing polyphenol or Vitamin B5 were investigated according to their recovering effects on hair damaged by bleaching. Surface morphology, CIE L*a*b* values, and tensile properties of hair were measured. The amount of protein leaking from hair was investigated using the Bradford protein assay. The amino acid composition of hair was examined using the HPLC instrument. Hair became severely damaged after bleaching, showing cuticle structure with surface melt down and rolled up tip, a decrease in tensile strength, an increase in protein leak, and an increase in the proportion of cysteic acid. When bleached hair was treated with the two types of hair toner, positive effects were seen in the recovery of cuticle structure and retention of bleached color, an increase in tensile strength, a decrease in protein leak up to certain days, and an increase in the retention of protein examined by the HPLC analysis of amino acids. Hair treated with B5 toner showed better effects on the increase of tensile strength compared to the hair treated with PP toner. Hair treated with PP toner showed better retention of color, less protein leak, and a lower proportion of cysteic acid compared to the hair treated with B5 toner.

Purposes of the study were to find out the joint effects of two salient appearance cues-hair colors and hair lengths on males fashion images, using 729 university students in Daejon city and a Chungnam province. The study was a quasi experiment; the dependent variables were hair lengths(4 levels) and hair colors(4 levels)and the dependent variable was a set of semantic different of scales which was consisted of 40 hi-polar adjectives, The data were analyzed by a factor analysis, 3-way ANOVA, and the results were as follows. Hair lengths effected on the image of five dimensions, salient, social, potency, evaluate and dynamics while hair colors effected on salients, social and potency dimensions. The most significant interaction effect between hair color and lengths were existed on the salient image: For the longer haired males, the color effects became less evident then normal to shorten haired males and it can be concluded that when two salient cues were combined one cue's effect became discounted.

A sensitive method for the determination of methamphetamine(MA) and amphetamine(AM) in hair was developed by gas chromatography/mass spectrometry using stable isotope-labeled internal standards, amphetamine-d$_{5}$ and methamphetamine-d$_{5}$. Hair sample was washed with MeOH, incubated with MeOH(I% HCI) overnight at $37^{\circ}C$ while stirring and extracted using solid phase extraction column on a vacuum manifold. The extract obtained was pentafluoropropionated, and applied to GC/MS. The calibration curves of MA and AM were linear from 2.5 to 250 ng (r>0.99 for both). The limit of detection was 0.1 ng/mg in hair and cut-off level was set at 0.25 ng/mg for both. Hair samples of 27 MA abusers showed positive results in the range 0.7 to 106.8 ng/mg. AM, its metabolite, was detected in 20 out of 27 samples. The ratio of MA versus AM was 4.6~38.3 in specimens. Hair analysis for methamphetamine by GC/MS is an effective method for identifying long-term drug abusers.

This thesis aims to investigate the morphologic relationship among the neckline, collar, and hair style, in which the width and height were measured by selecting the representative costumes from 16th to 19th centuries. The pieces of 170 pictures selected by fashion experts were cut in the same condition, with the part of the end of shoulder, head, and chest all placed on the equal level. The products were directly measured by a team of 3 specialists for verification of this study, of which results were calculated into average. The values of output were categorized into the unit of decade and finally into a graph of variation, in which the trend and relationship were evaluated according to the width and height. In 16th century, the width and height of the neckline were inversely proportional to those of hair style, while those of collar were proportional to those of hair style. In 17th century, the width and height of the hair style were proportional to those of neckline and collar. In 18th century, those of the neckline were inversely proportional to the hair style, with no collar found. In 19th century, the width of the neckline and collar were proportional to that of the hair style, while the height of the neckline and collar were inversely proportional to that of the hair style. The analysis of the morphologic relationship among neckline, collar, and hair style resulting from this study revealed that the change of the hair style took place corresponding to those of neckline and collar. Generally, the width of the hair style was found to be more resistant to change, compared to those of neckline and collar that were more susceptible. The height of the neckline was more resistant to change, compared to those of the hair style and collar presenting their frequently fluctuating height. Conclusively, the factor of height rather than that of width showed more dominant proportions, because the various forms of the collar and hair style evolved in terms of the height rather that width, relative to that of the neckline.

This study was to investigate the effect of manufacturing an avocado oil-added formulation and applying it to damaged hair. The experimental materials were prepared by adding avocado oil contents of 0 g, 3 g, 6 g, and 9 g to the perm base agent. It was applied to 4 damaged hair samples with the prepared formulation for comparative analysis. Tensile strength, absorbance using methylene blue, and gloss were measured as measurement methods for the effect on damaged hair. Statistical analysis was performed for the reliability of the research results. As a result of the tensile strength measurement, it was found that the tensile strength of the sample applied with the formulation containing 6 g and 9 g to the sample increased, affecting damaged hair. As a result of the absorbance analysis using methylene blue, it was found that the absorbance of all samples applied by adding oil decreased, affecting damaged hair. The gloss measurement result was found to affect damaged hair when 6 g and 9 g were added. The conclusion is that avocado oil affects damaged hair, so it is thought that it will have an effect of improving hair.

The purpose of this study were to investigate the influences of objectified body consciousness and body esteem on the weight and hair management behaviors of females. The questionnaires were administrated to 632 female residents of the Gwangju city, Korea. The SPSS for Windows 18.0 Statistics Package was used for data analysis. To verify the formulated hypotheses, descriptive statistical analysis, factor analysis, reliability analysis(Cronbach's ${\alpha}$), regression analysis, path analysis were used. The results were as follows. First, objectified body consciousness was divided into three factors: body shame, body surveillance, and appearance control beliefs. objectified body consciousness turned out to have positive influences on overall weight management behaviors and hair management behaviors. Second, objectified body consciousness appeared to have positive influence on overall body esteem. When the influences were further examined, body surveillance turned out to have significant positive influence on body esteem, whereas body shame and appearance control beliefs seemed to have few significant influences on body esteem. Third, body esteem appeared to have significant positive influence on all weight management behaviors and hair management behaviors. Fourth, it was found that objectified body consciousness had direct impact on the weight management behaviors and hair management behaviors without mediation body esteem.

The purpose of this study was to investigate the effects of the hair style, and perceiver's generation on the perception of a high schoolgirl's image. A quasi-experimental method by questionnaire was used. The subjects were 253 high schoolgirls and their mothers living in Jinju. The data were analyzed by using frequency, factor analysis, Cronbach's alpha-reliability coefficient, three-way ANOVA, and Duncan's multiple ranges test. The high schoolgirl's image was derived in five dimensions by factor analysis: schoolgirl look, prettiness, individuality, activeness, and cuteness. In the image based on the hair length, it was assessed that the short cut and the bobbed hair styles looked more like school girls. And the short cut and long hair styles were considered as showing individuality. On the other hand, the bobbed hair style was assessed as cuter than styles of other lengths. For the bangs, the short bangs were found to more school-girl look and cuter than the long bangs. The mother group, whose ages were older than that of the other group, evaluated that the stimulative pictures had more school-girl look, individuality, prettiness, activeness and cuteness, compared to how the school girl group evaluated. It was shown that the generation gap produced different opinions about the stimulative pictures. Therefore hair style, bangs style, and difference in generations were found to be the variables affecting perception of high school girl image.

The pre-treatment condition affects on the element analysis of inductively coupled plasma (ICP). In this study the pre-treatment condition of ICP has been studied to quantify elements in dog's hair. The hair samples were collected from twelve female Beagles by clipping them into 1 or 2 cm at the back neck. The qualitative and quantitative analysis of elements in hairs were performed by using ICP. By ICP nine elements were qualitatively detected and quantitatively analyzed (Ca, Cu, Fe, K, Mg, Na, P, Se, Zn). The measured amounts of elements were compared between 3 step and 2 step procedures which were with and without the acetone based washing step. The quantitative analysis showed that the concentrations of K, Na, P, and Se were significantly decreased in hair samples with acetone-based washing (p < 0.005 or 0.001) unlike those without the acetone-based washing. It implied that some minerals are lost by the acetone based washing during the sample preparation step. Therefore, the acetone based washing process is not suitable for quantifying elements in dog's hair. In addition, the results of qualitative and quantitative analysis were compared. Although there was a difference in absolute values of elemental contents in hair, the results of qualitative and quantitative analysis were significantly correlated each other. This finding suggested that the results of qualitative analysis can be used to monitor elemental contents in dog's hair.
