The purpose of this study was to identify the effects of the sensation seeking and body image on female adolescents' clothing behavior and hair style attitude. The data was collected from 390 high school girls living in Seoul, via a self·administered questionnaires, and were analyzed by frequency, factor analysis, reliability test, Pearson's correlation, and multiple regression. The results of this study was as follows : 1) Three factors of body images were self appearance evaluation, appearance orientation and fitness orientation. Five factors of clothing attitudes were fashion/clothing interest, clothing exhibition, social approval, psychological dependence on clothing and fashion leadership. And three factors of hair style attitudes were interest in hair style, individuality in hair style and dependency on hair designer. 2) As the result of analyzing the effects of sensation seeking and body image on clothing behavior, fashion/clothing interest was explained by appearance orientation and fitness orientation, and clothing exhibition by sensation seeking and appearance orientation, and social approval by appearance orientation, self appearance evaluation and body cathexis, and fashion leadership by appearance orientation, fitness orientation and self appearance evaluation, and clothing conformity to the self-entertainer by appearance orientation, sensation seeking and fitness orientation, and appearance related delinquency by sensation seeking, appearance orientation, fitness orientation, self appearance evaluation. 3) As the result of analyzing the effects of sensation seeking and body image on hair style attitudes, interest in hair style was explained by the factors such as appearance orientation, sensation seeking, fitness orientation, and body cathexis, and individuality in hair style by appearance orientation, sensation seeking and self appearance evaluation, and dependency on hair designer by body cathexis.

Purpose: Zinc deficiency can induce serious clinical problems in the gastrointestinal (GI) system and immune system and can affect growth and development. It is more severe in younger patients. Chronic zinc deficiency is reflected more precisely in hair than in serum. We studied hair zinc levels and other hair and serum micronutrients in chronic malnourished children to identify which micronutrients are affected or correlated with the other ones. Methods: Hair mineral analyses were performed in 56 children (age, 1-15 years) presenting with malnutrition, poor growth, poor appetite, anorexia, with/without other GI symptoms (diarrhea, abdominal pain, constipation) from August 2012 to March 2015. Biochemical studies for macronutrients and major micronutrients were also conducted. Results: Hair zinc deficiency was diagnosed in 88%, and serum zinc deficiency was diagnosed in 55% of the children. There was no statistical correlation between serum and tissue zinc level. Hair zinc levels were highly correlated with serum vitamin D (r=-0.479, p=0.001), which also showed correlation with hair levels of magnesium and calcium. (r=0.564, 0.339, p=0.001, 0.011). Hair calcium level was correlated with serum pre-albumin (r=0.423, p=0.001). These correlations may explain the phenomenon that the major clinical manifestation of zinc deficiency is poor body growth. Clinical symptoms were resolved in most children after zinc supplementation. Conclusion: Hair zinc and mineral analyses are useful as a therapeutic guide in the clinical investigation of children with malnutrition and poor growth.

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.

An analytical method was developed for evaluating the cannabidiol (CBO), cannabinol (CBN), ${\Delta}^9-tetrahydrocannabinol$ $({\Delta}^9-THC)$ level in human hair using gas chromatography-mass spectrometry (GC-MS). Hair samples (50mg) were washed with isopropyl alcohol and cut into small fragments (< 1mm). After adding a deuterated internal standard, the hair samples were incubated in 1.0M NaOH for 10 min at $95^{\circ}C$. The analytes from the resulting hydrolyzed samples were extracted using a mixture of n-hexane-ethyl acetate (75:25, v/v). The extracts were then evaporated, derivatized, and injected into the GC-MS. The recovery ranges of CBD, CBN, and ${\Delta}^9-THC$ at three concentration levels were $37.9-94.5\%$ with good correlation coefficients $(r^2>0.9989)$. The intra-day precision and accuracy ranged from $-9.4\%\;to\;17.7\%$, and the inter-day precision and accuracy ranged from $-15.5\%\;to\;14.5\%$, respectively. The limits of detection (LOD) for CBD, CBN, and ${\Delta}^9-THC$ were 0.005, 0.002, and 0.006 ng/mg, respectively. The applicability of this method of analyzing the hair samples from cannabis abusers was demonstrated.

Appearance is a means of competitiveness for modern people, and one of the factors that harms the desires of modern people is white hair. For the modern man who needs to express beautiful appearance to others by covering white moth, we performed hair analysis after white moth hair dye treatment. The maximum modulus and tangential modulus according to the maximum load, maximum tensile strength, maximum elongation, breaking load, fracture strength, elongation at break, and evaluation interval between 1N-3N experimental group and control group of 1N-Respectively. Maximum load, maximum tensile strength, breaking load and breaking strength tended to be larger than those of the control group, while the maximum elongation and breaking elongation were the highest in the control group and the elongation decreased with the experimental group treatment. The maximum modulus and tangential modulus of the 1N-3N test group were higher than those of the control group at 0~0.15 and 0.15~2.5, respectively. Based on the study on the cosmetic changes of the hair before and after the treatment, it can be used as a basic data to select the correct oxidative hair dye product, the proper amount of application and the time to leave.

The beauty industry of today tends to gradually develope as one of the important marketing strategies along with the total fashion sector. Hair color, being one of the factors of hair style, especially builds his or her own image and even becomes the nonverbal communication method which let others know him/herself. Therefore, women's needs and expectations of hair coloring are varied. To meet these need, it is urgent to figure out, most of all, the status of customers' awareness about hair coloring. Thus, in this study, research and analysis on hair coloring were made, focusing on the women utilizing 20 beauty shops in Changwon city. And the goal that this study set is to use as the study material for the hair coloring consulting in the beauty industry and the basic data for marketing in the industry job-sites. The conclusion by the three factors(age, job, monthly income) were as follows: 1. Dandyism was on the 1st order in the reason for coloring hair regardless of age, job, and monthly income. This seems to be speaking for the change of women's awareness of coloring hair. 2. The subject of making decision upon whether she was going to color her hair or not was herself regardless of age, job, and monthly income. Among the people belong to these three factors, brown was the color in overall preference. 3. More than half of those who belong to the three factors were not aware of the hair color, but their senses and interest in the color in vogue were high. 4. In terms of the hair coloring periodic time, many people had $2{\sim}3$months, but it was possible to know that they were interested in improving their images, considering the fact that most of the salaried people had their hair dyed within a month and the people in service job over a month. 5. The acquaintance around me had the strongest effect in collecting information from the people in those three factors and mass media was the next. The results of this study, in my opinion, would help the customers have beautiful and healthy hair and make images of their own by making the hair designers develope professional knowledges and skills on the hair coloring and improve the quality of beauty services.

This study investigates thermal deformation due to fan shape of a hair dryer. In this study, thermal analysis showed that the shape of an electric fan results in lower temperature than that of a sieve frame. Among the shapes of electric fans, the temperature change decreases as the number of wings decreases. As a result of thermal deformation, model 4 (sieve frame shape) showed increased change of deformation compared to models 1, 2, and 3 (with electric fan shapes). Thus, the model 1 dryer with the sieve frame shape is shown to have the least durability among models 1, 2, 3, and 4. It is thought that the analysis results of this study can be applied to durability improvement and safer design of hair dryers.

Nonlinear transient analysis is executed to obtain the temperature distribution, and to evaluate the thermal stress of brake drum by using FEA(finite element analysis). The result induces the reason why hair crack and the cause of drum failure occurs and the way how stress of drum decreases. The temperature of drum is in proportion to the drum thickness and it processes nonlinear changes at every points of drum. The higher bulk temperature raises, the more stress difference between inner surface and outer surface makes and the highest bulk temperature is at the corner section. It is necessary for the diminishment of the drum stress to make air flow, between drum and rim, move lively and use the materials of higher conductivity. The hair crack and the cause of drum failure seem to be started at the near corner section.

Purpose - The purpose of this paper is to find out the effect of changes in the differentiated "servicescape" on the business performance in the hair salon industry using a case study. For this, we selected hair salon M located in Suwon. The shop is innovatively different from existing shops in terms of spatial layout and functionality. We conducted in-depth research, beginning with the launch of the shop concept through investment and ongoing stable sales. Research design, data, and methodology - The M hair salon is a start up shop providing a differentiated servicescape (physical environment where the service takes place) located in Suwon, Yeongtong-gu. We conducted research to investigate how spatial layout and functionality of the servicescape impact customers' perceived quality. The interview period and case analysis was May 2014 through March 2015, covering 11 months. To conduct the case analysis, we analyzed the spatial layout and functionality of existing shops and interviewed customers and experts about the difference between hair salon M and existing shops. Results - Our results found clues to the positive effect of spatial layout and functionality among servicescape factors on perceived service quality at the salon. The shop showed a fast payback of the principal investment, growth potential in contrast to competitors near the salon, and 45 percent returning customers. The problem with the spatial layout at existing shops was that customers were aware of the way other people were looking at them, since viewing angles overlapped, therefore there was a limitation to the relationship intensity with an exclusive hair designer. In contrast, the layout of the stands at the M salon kept the number of dressing stands limited to maximize the customer's emotional response. Additionally, because of the new layout of dressing stands hiding other customer voices and appearance in the salon, customers perceived their service space as independent. Therefore, they did not have to focus on their personal emotional response, which was one of the advantages of the new layout. Conclusions - This study conducted case study analysis by offering a new perspective focusing on spatial layout, previously not considered as an independent variable of quality evaluations and customer satisfaction in existing literature on hair salon management. Therefore, this study contributes to the field by offering an opportunity to discover the causal relationships between the overlooked physical environment and a customer's perceived quality. However, a process objectifying the results of the study through empirical analysis and hypotheses is needed to overcome the limitations of the case study approach and generalize the results. Moreover, it would be beneficial to conduct further empirical study of the relationship between the spatial layout provided in the case and a customer's emotional response and change in mood. In addition, an analysis is needed regarding how customers feel about the factors using the Kano Model. These suggestions would be considered in further study.
