While associations between trace elements and heavy metals with prostate cancer are still debatable, they have been considered as risk factors for prostate cancer. Thus, this study aimed to detect any links between selected minerals and heavy metals including Se, Zn, Cu, Mn and Fe with prostate cancer. A case control study was carried out among 100 subjects (case n=50, control n=50), matched for age and ethnicity. Trace elements and heavy metals level in hair and nail samples were determined by ICP-MS. Mean selenium levels in hair and nail of the cases were significantly lower as compared to controls. A similar trend was noted for zinc in both hair and nail samples, whereas the mean level of copper was significantly higher in cases than controls. Similar elevation was noted for iron and manganese (p<0.05 for all parameters). Low levels of selenium and zinc and high levels of copper, iron and manganese appear to be associated with the risk of prostate cancer. Further studies to elucidate the causal mechanisms and appropriate chemopreventive measures are needed.

Nutritional and health status was assessed in the 86 healthy elderly women who aged 65 through 96 and resided in nursing home in chonbuk area. Nutritional status was determined by dietary intake, anthropometric and hematological indices and hair elements. Correlation analysis among nutritional indices were performed to identify the factors which related specifically to nutritional status of the elderly. Nutrients intake below two-thirds of the RDA were Ca, riboflavin and niacin. Especially mean Ca intake was only 51.9% of RDA and most of nutrients intake were decreased as theri age increased. Height, body weight and mid upper arm circumference were decreased with age but W/H ratio did not differ among age groups. These data suggested that body fat accumulation did not change with age but lean body mass was decreased with age in the elderly. Waist circumference was positively correlated to dietary fat intake, and body weight, BMI, waist and hip circumferences and total body fat were positively correlated with serum LDC/HDL ratio. It could be concluded anthropometric indices were good indicator that reflect the lipid nutritional status in elderly women. Hematological indices, Hb, RBC, MCH, albumin, globulin, transferrin levels, belonged to normal ranges of aged women. However, the lowest Hb level showed in the oldest-old group(aged 85 and over years group). The avalilavilty of hair analysis to measure nutritional status was tested. There were not found any significant correlations between many kinds of nutritional indices and hair elements except hair Zn content which was positively correlated with BMI.

The method for the estimation of trace elements in hair is studied on this paper modifying the circular paper chromatography method shown by Giri and Balakrishnan for the estimation of vitamins from the multivitamin preparation. The elements studied are Ni, Al, Mn, Mg, Zn, Ca, Co, Cu, and Fe. The content of the element is estimated quantitatively by comparison the size and the color density of spots of the standard chromatogram prepared by the known amount of each standard substance and the chromatogram prepared from sample solution, after checking those chromatogram qualitatively. The comparative study has been made between the results from this method and the results from the other methods which are applying routinely at this laboratories. The experimental errors at each elements were within 10% limits. There was no interference between each elements. It is recommendable that this method can be applied to treat numerous speciemens saving times within experimental error of 10%.

Purpose : The reliability of hair mineral analyses regarding nutritional status, environmental exposure or diseases is controversial. The aim of this study was to determine the normal reference range of hair mineral concentration of Korean children. Methods : We examined hair mineral concentrations of 223 children(3-12 yrs old, 110 boys, 113 girls, mean age $8.8{\pm}2.2$ yrs old) living in the northern area of Seoul. The trace elements including six toxic elements(Al, As, Cd, Ba, Hg, Pb) and 11 nutritional elements(Na, Mg, P, K, Ca, Cr, Mn, Fe, Cu, Zn, Se) were analyzed by inductive coupled plasma mass spectrometry(ICP-MS). Results : The mean concentrations of Ca and Mg were higher in girls than in boys. The mean concentrations of Cd, Pb and Cr were higher in boys than girls. The Zn, Ca, Mg, Cu and Hg levels in hair samples were positively correlated with increasing age. The Zn levels of the Korean children's hair samples appear to be lower than that of other countries' reference values. Conclusion : There are considerable differences in hair mineral concentrations by age, sex and race. Additional research is needed to establish Korean reference values, and to evaluate the usefulness of hair mineral analyses as a screening tool for nutrition- and environment-related childhood diseases.

After artificial intelligence was trained with the data on the concentration of essential mineral elements in hair, the age was predicted by the concentration of mineral elements in the hair of the subject, and the result was compared with the actual age of the subject, and the correlation was investigated. The total number of hair data was 296, of which 2/3 were used for AI learning and 1/3 was used as the subject data. There was a correlation of 0. 678 between the actual age of the young subjects under the age of 25 and the age predicted by the AI. There was almost no correlation in the middle-aged subjects group, and there was a weak correlation of 0.522 in the elderly subject group. In order to secure the usefulness of artificial intelligence using hair mineral element concentration data, it is necessary to provide a larger number of data to the artificial intelligence.

Several heavy metals are known to give some kinds of mental retardation although abnormal X-chromosome is closely connected with genetic disease such as mental retardation. This study dealt with the influence of minerals in the hair of mental retardation people. Minerals were analyzed by Inductively Coupled Plasma Mass Spectrometer (Sciex Elan 6100, Perkin-Elmer corporation, Foster, CA, USA). The nutritional elements such as Ca, Na, K were higher level (p<0.01) in normal group than in the mental retardation group. The toxic elements such as Cd (p<0.01) and As were higher level in the mental retardation group than in normal group. But Pb is not significant difference among the all groups including normal group.

Purpose: Patients with chronic gastrointestinal disease are at risk for trace element deficiency due to impaired absorption and gastrointestinal loss. The aim of this study was to evaluate the trace element status of patients with gastrointestinal disease by blood and hair analysis, and to determine the usefulness of hair mineral analysis for diagnosing trace element deficiency not detected by a blood test. Methods: An analysis of hair minerals was performed and compared with blood mineral analysis in 13 patients with chronic gastrointestinal disease. The concentration of each element in the hair and blood was compared in the subgroups based on parenteral nutritional support or clinical symptoms. Results: Almost all patients had trace element deficiency. The trace elements deficient in the blood or hair analysis included zinc, selenium and copper. The hair zinc concentration was significantly lower in the group receiving parenteral nutritional support. The hair selenium concentration was statistically associated with the clinical symptoms of hair loss, brittle hair and loss of hair pigmentation. Conclusion: The results of this study suggest that patients with chronic gastrointestinal disease should receive adequate zinc and selenium replacement to avoid trace element deficiency especially when treated with long-term parenteral nutrition. Hair mineral analysis is useful as a complementary tool for the detection of a trace element deficiency.

Man's search for beauty has been going on from prehistoric time until today, and the pursuit of beauty has been progressing, regardless of the times, as a human psychological desire. In the search for beauty, hair and make-up have been subjects of interest for a long time, but the development of designs for these two aspects are still behind compared to other areas. Therefore, this study aims to propose various new and creative hair and make-up designs and to suggest their possible development. Using existing literature, this paper studied the skin color and hair color of Koreans that had been studied in earlier papers. It also aimed to understand the hair color and hair color images that are suitable for each skin color, classify the modern hair and make-up trends into different images - natural, surrealistic, minimalist, and cyber look, and also analyze them. Actual hair and make-up were also designed based on these images. To depict the natural image, the make-up was made intentionally dark as the skin color; natural materials were used for hair decoration; brown and yellow were used for the eye shadow to express the natural and romantic image of autumn, in general. Second, in the work expressing the surrealistic image, the hair was creatively decorated with a collage of various objects; yellow, green, and red eye shadows and lip expression were used to visually achieve the surrealistic fantasy look. Thirdly, in the work expressing the minimalist image, hair style with bangs without any hair decoration was used; make-up colors were minimized as well, creating a generally simple image. Finally, for the work expressing the cyber image, metallic material decoration was used on a puff-up hair style; the cyber image was emphasized through the use of graphical elements in the make-up.
