Chitosan, a natural cationic macromolecular material, has been known for its moisturizing and healing effect due to the coating action based on strong ionic bonding when the chitosan is treated on hair strands. In this study, the acidic aqueous chitosan solution was prepared to treat healthy hair, and damaged hair due to bleaching, relatively thin hair and thick hair specimens. The chitosan treatment effect was reviewed by comparing spectrophotometric and mechanical characteristics of the chitosan treated and untreated specimens. Electrostatic voltage was somewhat reduced after the chitosan treatment. Smoothly coated surface was observed, in the SEM images, especially for damaged hair specimens. The values of breaking strength, which is one of the indicators of the internal characteristics of hair, was high in the case of chitosan treated samples. The values of elongation was also high in the case of chitosan treated samples, which proves the chitosan treatment effect. The friction force, one of the indicators of surface characteristics, was reduced for the case of chitosan treated samples.

In the 17th century, men's hair style showed a dramatical change to thick hair style with femineity. During the 17th century, men wore their hair longer than at any other time in the history of western culture. Men's hairs in the early 17th century were defined as short hair style influenced by ruff collar of renaissance and thick beards and moustaches During the mid 17th century, shoulder-length hair style was predominant over all classes. As hair style became long, beards and moustaches gradually declined in favour: from 1625, small neat beards, and moustaches turned up at the ends, got progressively smaller, and by 1650 the beard was only small tuft on the chin, disappearing completely by 1680. In the late 17th century, very long, thick and shiny hair got a great popularity with the gorgeous and decorative baroque costume dominated over the entire Europe. The habit of adding false hair when natural hair was deficient led to the introduction of the periwig, which became an essential part of a fashionable man's attire. Wiggery were widely used to express curled and puffed hairs more exaggerated. As the long hair style with wiggery became popular, various style of beard and moustache got smallar so that they were ended up in entire disappearance in the end of the 17th century.

Objectives : To evaluate the DNA damage by hair dyeing in human lymphocytes Methods : Comet assays were carried out to evaluate the DNA damage in lymphocytes by hair dyeing. Twenty subjects were selected from women volunteers whose age ranged from 55 to 67 year old. All subjects had no smoking history. Blood samples were collected before and 6 hours after hair dyeing. DNA damage was evaluated by means of the tail moments, which were quantified by a KOMET 4.0 image analysis system. Results : The tail moments before hair dyeing showed no significant differences among subjects except for the high frequency group. The mean values of the tail moments in subjects with low and high frequencies of hair dyeing were 1.39 and 1.77, respectively (p<0.05). The tail moments after hair dyeing increased significantly, The mean values of tail moments in subjects before and after hair dyeing were 1.45 and 1.79, respectively (p<0.01). However, the difference levels of DNA damage in lymphocytes before and after hair dyeing were found to be slightly lower in both the dietary supplement taking group and high frequency group. Conclusions : The high frequency group appears to have a higher level of DNA damage than the low frequency group before hair dyeing. DNA damage in lymphocytes was found to be significantly higher in the volunteers after hair dyeing. In this study, the related factors such as high frequency and taking dietary supplements appeard to reduce DNA damage in lymphocytes after hair dyeing.

In this paper, we proposed automatic searching algorithm of thresholding value using multilevel thresholding for face segmentation from input bust image effectively. The proposed algorithm extracted the thresholding value of brightness that is formed background region, face region and hair region without illumination, background and face size from input image. The statistical projection analysis project the brightness of multilevel thresholding image into horizontal and vertical direction and decide the thresholding value of face. And the algorithm extracted elliptical type block of face from input image in order to reduce the back ground region and hair region efficiently. The proposed algorithm can reduce searching area of feature extraction and processing time for face recognication.

The purpose of this study was to examine the effect of clothing type and hair style on men’s impression formation. The experimental design was 4×2×2×2 (clothing type×hair style×perceiver’s age×perceiver’s role) factorial design with between-subjects design. The stimuli of color photographs of male in his 20's model and semantic differential scale were used. The data were obtained from questionnaires completed by 881 men and women in the metropolitan area of Seoul. The SPSS package was used for data analysis which includes factor analysis, t-test, and Cronbach’s a to measure the reliability. This study showed the following results. Four factors were derived to account for the dimensions of impression formation. These were dignity, activity, individual character, and social intercourse. Men evaluated individual character factor higher than women did. Dignity factor was evaluated higher by students, while social intercourse factor was evaluated higher by office workers. The clothing type of shirts/pants was evaluated to be more active and more sociable than of jacket/pants. Men wanted to exhibit natty image and women did elegant image through clothes.

The purpose of this study is research on the characteristics of post-modernism expressed on western hair styles in the late 20th century. Therefore this thesis analyzed the relationship of modernism & the hair styles of that mage and post-modernism & the hair styles of that mage. That will re-illuminate the same beauty worth of same age as to accurate the concept of post-modernism & the hair styles of that mage. And the last, criticizing the post-modernism design and that hair design, helping to find new trends. The method of this study was the literature research & analysis of visual materials focus on upper bust image that can know the relationship of modernism & the hair styles of that mage, and post-modernism & the hair styles of that mage. First, the literature research is composed of analysis of theses, magazines on art, clothing and cosmetology having the contents of 20th century western culture, art and hair styles. Second, the analysis of visual materials is composed of analysis of video films, slide films and photographs of books, magazines, and internet home-pages. Modern western hair styles, appeared after 1910's, is represented as a short cut & permanent wave. That express experimentalism, functionalism, and purism, that is same as the other art's trend of same age. Post-modern western hair styles, appeared after 1960's, also show the same trend with same age's. This summarized & characterized 8 categories; historical method, pluralism, negotiation, escape from the formality, recovery of humanity, ornament, connection with race, metaphor & symbolism. But post-modernism concentrating pluralism makes easy making low quality art and absence of criticism, so this thesis criticised it 5 categories; absence of ideas, absence of the social sense of responsibility, lost of one's characteristics, decline of skills, decline of worth of usages.

In this paper, we propose a reconstruction technique of the lost hair region for 3D human actor modeling. An active depth sensor system can simultaneously capture both color and geometry information of any objects in real-time. However, it cannot acquire some regions whose surfaces are shiny and dark. Therefore, to get a natural 3D human model, the lost region in depth image should be recovered, especially human hair region. The recovery is performed using both color and depth images. We find out the hair region using color image first. After the boundary of hair region is estimated, the inside of hair region is estimated using an interpolation technique and closing operation. A 3D mesh model is generated after performing a series of operations including adaptive sampling, triangulation, mesh smoothing, and texture mapping. The proposed method can generate recovered 3D mesh stream automatically. The final 3D human model allows the user view interaction or haptic interaction in realistic broadcasting system.

The human face can provide a great deal of information in regard to his/her race, age, sex, personality, feeling, psychology, mental state, health condition and ect. If we pay a close attention to the aging process, we are able to find out that there are recognizable phenomena such as eyelid drooping, cheek drooping, forehead furrowing, hair falling-out, the hair becomes gray and etc. This paper proposes that the method to estimate the age by analyzing these feature components for the facial image. Ang we also introduce the method of facial image synthesis in accordance with the cange of age. The feature components according to the change of age can be obtainec by dividing the facial image into the 3-dimensional shape of a face and the texture of a face and then analyzing the principle component respectively using 3-dimensional model. We assume the age of the facial image by comparing the extracted feature component to the facial image and synthesize the resulted image by adding or subtracting the feature component to/from the facial image. As a resurt of this simulation, we have obtained the age changed ficial image of high quality.

Objective : The purpose of this study is to report the hair regrowth effect of Gagamyeonryunggobon-dan on ICR mice from measuring the change of diverse factors.Methods : Gagamyeonryunggobon-dan was treated by oral administration with 2.5㎎/㎏/day amount for 3 weeks per mouse everyday. Hair regrowth was estimated by change of morphology, angiogenesis, hair follicle activation. The change of morphology was observed with external, internal change and sebaceous gland. Angiogenesis was estimated by image analysis, capillary distribution and angiogenic chemokine(MIP-2). Hair follicle activation was estimated by PCNA, IGF-2 and serotonin.Results : 1. Gagamyeonryunggobon-dan treated group had more and thicker hairs than the group not treated. Especially well developed sebaceous glands were seen in dermis of treated group. 2. Gagamyeonryunggobon-dan treated group had more capillaries near hair follicles of subcutaneous layer and more 2019% MIP-2 positive activity than the group not treated. 3. Gagamyeonryunggobon-dan treated group increased positive activity up to 596% in PCNA, 187% in IGF-2 and 547% in serotonin more than the group not treated.Conclusion : These results shows that Gagamyeonryunggobon-dan have the hair regrowth effect through verifying change of morphology, angiogenesis, chemokines. Consequently Gagamyeonryunggobon-dan is expected to apply to take care of extensive hair loss symptoms.
