  • The purpose of this study is to examine by which correlation the pluralistic phenomenon in text is functioned in comparison with hair style and fashion in collection. As a result, the pluralistic image in text, which was shown in modern fashion, was indicated to be pluralistic phenomenon by gender, T.P.O, coordination, and material. The pluralistic image in text for hair style can be known to have been indicated to be the pluralistic phenomenon in text for gender and to be the pluralistic phenomenon in text according to material and cultural category. As for a method of this study, it did put limitation on the part that is shown in the fashion collection from 2001 to 2007, analyzed hair-style features centering on photos, which were extracted from style.com, the online site of specializing in fashion, and carried out a literature research side by side with the theoretical background on intertextuality. The analysis in work according to the pluralistic phenomenon in text made it possible for looking at with a new sight differently from the recognition in the past, and opened the potentiality for being able to understand lots of strange representations, which have been impossible so far. The process of imitating and reconstructing each text according to compositional principle led to possibly knowing the necessity of an artist's ability that can implement the originative world.

  • Purpose: This study was performed to evaluate the dietary nutrient intake status and hair mineral content of Korean young children. Methods: Fifty-five children who visited Seoul National University Bundang Hospital were divided into three groups by age: infants, toddlers, and preschoolers. The 24-hour recall method was used to collect the food intake data of the subjects. Hair mineral analysis was conducted using a Mass Spectrometer. Serum iron, ferritin, and calcium were also measured. Results: The mean energy intakes of the subjects were 730.3 kcal, 994.3 kcal, and 1,482.9 kcal for each age group. The mean percentage of energy intake compared to recommendation was 101.4% and was not different by age group. Toddlers of 37.8% and preschoolers of 54.5% consumed less than the Estimated Average Requirement (EAR) of calcium. Infants of 28.6%, toddlers of 10.8% and preschoolers of 9.1% consumed less than the EAR of iron. In the case of zinc, copper, and selenium, only 0% to 5% of toddlers and none of the preschoolers consumed less than the EAR of those minerals. The hair calcium, iron and copper concentrations were lower in toddlers and preschoolers than those in infants. Serum calcium levels of preschoolers were significantly lower than those of infants, whereas serum iron and ferritin levels were not. Conclusion: Hair calcium, iron, and copper concentrations were significantly lower in toddlers and preschoolers than in infants. Insufficient dietary intake of calcium and iron seems to be related with decreased hair mineral contents in young children.

  • To overcome the harmful effects caused by conventional oxidative hair dyes, natural colorants becomes more popular in the hair dyeing. By extracting Sagassum fusiforme powders with aqueous alkaline solution as a solvent at 130℃ for 60 minutes, a fucoxanthin concentration of up to 216㎍/ml can be obtained. UV/Vis analysis was used to prove the presence of fucoxanthin in the extract powder. A K/S value of 23.8 can be obtained when wool fabrics were dyed with the extract at 120℃ for 60 minutes under pH 2. The color fastness properties of the dyed wool fabrics were very good as indicated by rating 4 for laundering(color change), rating 3 or higher for rubbing, and rating 5 for light irradiation. The dyed wool fabric was found to have antimicrobial activity against Staphylococcus aureus. The antioxidant and antimicrobial activity of the Sagassum fusiforme extract can be an effective functional hair colorant. Hair dyeing with the extract formulation at 45℃ for 40 minutes under pH 5 accomplished a K/S value of 8.9. The color fastness of the dyed hair showed rating 3 against light irradiation, which increased to rating 5 with after-mordanting of tannin acid.

  • In this paper, we propose a technique that can express low-resolution hair and fur simulations in high-resolution without noise using ConvNet and geometric images of strands in the form of lines. Pairs between low-resolution and high-resolution data can be obtained through physics-based simulation, and a low-resolution-high-resolution data pair is established using the obtained data. The data used for training is used by converting the position of the hair strands into a geometric image. The hair and fur network proposed in this paper is used for an image synthesizer that upscales a low-resolution image to a high-resolution image. If the high-resolution geometry image obtained as a result of the test is converted back to high-resolution hair, it is possible to express the elastic movement of hair, which is difficult to express with a single mapping function. As for the performance of the synthesis result, it showed faster performance than the traditional physics-based simulation, and it can be easily executed without knowing complex numerical analysis.

  • 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.

  • The purpose of this study is to examine the influence of sociocultural attitudes toward appearance and narcissism on body stress. Questionnaires are being administered to 206 women in their 20's-50's living in Deagu and Kyunbook province. The Frequency, factor analysis, reliability analysis, correlation analysis, regression analysis, ANOVA, and Duncan-test are used for data analysis. Sociocultural attitudes toward appearance are categorized into media appearance internalization and social recognition of appearance. Narcissism factors are found to be leadership/privilege, ostentation, and superiority. Body stress is categorized into 4 factors: weight stress, skin aging stress, body dissatisfaction, and hair stress. Sociocultural attitudes toward appearance was related to the sub-variables of narcissism, and body stress. Media appearance internalization is the sun-variable of sociocultural attitudes toward appearance and has significant effects on weight stress, skin aging stress, and body dissatisfaction sub-variables for body stress. Ostentation, and superiority being the sub-variables of narcissism, have significant effects on weight stress, skin aging stress, body dissatisfaction, and hair stress, the sub-variables for body stress. Ages of women display distinctions between the sub-variables in sociocultural attitudes toward appearance such media appearance internalization, and in narcissism such leadership/privilege, ostentation, superiority, and body stress such weight stress, skin aging stress, body dissatisfaction, and hair stress. This result can be a necessary base line data for adult women's appearance management by examining the influence of the attitude toward the appearance developed from the relationship with people around body stress.
