The structure and physiological function of human skin continuously weaken due to growing older. The reasons of aging from external conditions are long term exposure to sun, wind, heat, cigarette smoke, and etc. This also palmitoyl oligopeptide or ceramide oligopeptide are known asc ingredient stimulating collagens and have the effect of reproducing the upper level of skin. Acetyl hexapeptide is an ingredient that makes the skin and muscle suppler and reduces wrinkles. It is a major high function beauty ingredient that substitutes botox. After dividing 7%, 14%, and 20% Acetyl hexapeptide experimental groups as groups A, B, and C the control group and experiment groups' change of wrinkles, hair follicles, moisture content, and dead skin cells was analyzed. According to the results, Acetyl hexapeptide seems to affect wrinkles, hair follicles and moisture content contrasting to the control group. Experimental groups and control group showed similar change in dead skin cells. In contrast to the control group satisfaction of examines was affected in wrinkles, hair follicles and moisture but removing dead skin cells had similar result in experimental groups and control group.

This study was conducted to determine the kinetics of cyclohexane metabolites (the biomarker on cyclohexane exposure), the changes of hepatic cyclohexane metabolizing enzyme activities and the metabolites of cyclohexane in urine or serum. The rats were sacrificed at 2, 4, 8, 12 and 24 hr after administration of one dose of cyclohexane (1.56 g/kg body weight, i.p.). The metabolites of cyclohexane in urine were identified as cyclohexanol, cyclohexanone, trans-l,2-cyclohexanediol and 1,4-cyclohexanediol with cyclohexane metabolite being 124.00, 0.78, 23.28 and 2.75 (g/g of creatinine, $1\times10^{-3}$). Most of the cyclohexanol and trans-l,2-cyclohexanediol were determined to be in the form of $\beta-glucuronide$ conjugates, whereas cyclohexanone and 1 ,4-cyclohexanediol were found as free forms. In toxicokinetics of serum cyclohexane metabolites, cyclohexanol showed a rapid increase, reaching the plateau at 4 hr, after this time rapidly decreased throughout 24 hr. Changes of cyclohexanone also showed the similar pattern with cyclohexanol except somewhat lower concentration. Trans-l,2-cyclohexanediol, however, showed a gradual increase until 12 hr with the continued same levels throughout 24 hr. On the other hand, 1,4-cyclohexanediol was detected as trace levels at 4 and 12 hr, respectively. The administration of cyclohexane led to a significant increase of hepatic aniline hydroxylase activity from 2 to 8 hr. The activity of hepatic alcohol dehydrogenase showed a significant increase at 4 hr and then were recovered to the level of the control at 24 hr. On the other hand, there were no differences in liver weightlbody weight between the control and cyclohexane-treated animals. However, there were the changes of aniline hydroxylase and alcohol dehydrogenase activities on time-dependent pattern after cyclohexane treatment, which influence on the degree of cyclohexane metabolites both in blood and urine. These results suggest that differential determination of cyclohexane metabolites in urine and serum may be able to be as a biomarker of cyclohexane-exposure in the body. But in this fields further study is needed.

In this study, in order to analyze the air quality of the indoor environments of schools, we measured the indoor, outdoor and personal exposure concentration level of $PM_{10}$ for 40 classrooms(20 old, 20 new) in chungnam area from June 22 to July 19 and from November 21 to December 30, 2003. 1. Old classrooms contained more dust than new classrooms; the average of respirable dust is $43.27\;{\mu}g/m^3$ for new classrooms while $53.38\;{\mu}g/m^3$ for old one. The exposure concentration level of respirable dust in new classrooms were in summer higher outdoors than indoors. The values were indoors $46.71\;{\mu}g/m^3$, outdoors $50.46\;{\mu}g/m^3$, and personal $41.62\;{\mu}g/m^3$. Meanwhile in winter indoors had a higher concentration level than outdoors, the values being indoors $39.11\;{\mu}g/m^3$, outdoors $34.86\;{\mu}g/m^3$, and personal $49.01\;{\mu}g/m^3$. 2. Cr concentration level within dust was slightly higher in summer indoors ($101.50{\pm}32.10\;ng/m^3$) and outdoors ($100.89{\pm}35.18\;ng/m^3$) than winter indoors ($85.80{\pm}48.95\;ng/m^3$) and outdoors ($74.43{\pm}38.93\;ng/m^3$), but in personal concentration level, winter was higher. The results of this research show insufficient understanding of health risks from indoor air pollution, and shows possible health problems to students from school indoor air pollution. As such, a logical and systematic education program for students about the importance of indoor air quality should be carried out. Also the results of $PM_{10}$ concentration level measurements emphasize the need for regular measurements of indoor / outdoor and personal concentration level. New classrooms in particular needs to be used after measuring pollutants and safety, and requires installation of a ventilation device in all classrooms to improve air quality.

The primary objective of this study is to determine whether a diet supplemented with brown rice koji (BRK) results in a reduced stress response in rats and mice. BRK, which has been suggested as a candidate for use as a stress- and fatigue-fighting supplement, was compared with red ginseng extract (RG) for its stress-reducing potential. The animals in this study were divided into no-stress, stress, RG, and BRK groups of 8 to 10 animals each. Stress was induced by means of immobilization (being restrained in plastic tubes for 30 min and electroshock (0.5 mA in mice or 2 mA in rats for 5 min). The no-stress group was not exposed to stress. Rats in the RG group received oral doses of 200 mg RG extract/kg body weight daily. The BRK group was fed a 30% BRK diet and exposed to stress. Animals were given supplements for 7 days before being exposed to stress, and then were given supplements for 5 days with exposure to stress. When the stress exposure ended, the animals were observed for stress-related changes in behavior and their plasma corticosterone levels were measured. BRK supplementation was associated with a partial blockade of the effects of stress on locomotion and elevated plus-maze test results in rats and mice. It was also associated with a partial reduction in stress-induced behaviors such as freezing, burrowing, smelling, face-washing, and rearing. BRK supplementation did not have a significant effect on plasma corticosterone levels, which were increased in the animals exposed to stress (p<0.01). The mice in the RG group received RG in water (2 mg RG/ mL $H_2O$), and the BRK group received a 30% BRK diet (weight) for 7 days. Both groups were evaluated for signs of fatigue. BRK supplementation increased endurance, as indicated by time on the rota-rod, in cold water, and on the horizontal wire. These results suggest that BRK supplementation partially protects the animal from the effects of stress and may also contribute to resistance to fatigue on physical exertion.

The face of the Seated Stone Buddha ^{Korean Treasure No.84} of Sinboksa Templesite in Gangneung was contaminated with a glossy resin, spoiling its beauty. The contaminants covered the face, the forehead of the urna, to the bottom of the jaw. FT-IR analysis on a sample of the contaminants identified the substance as cyanoacrylate instant adhesive, which can normally be melted with acetone and removed with a swab. However, given that the surface of the statue was severely weathered from prolonged open-air exposure, alternative removal procedures were considered, to minimize the possibility of physical damage. After research, two removal procedures were utilized: one procedure involving poultices, which had been used to remove graffiti from the Samjeondobi Stele, and one procedure involving steam sterilization, which has been used to remove resin from pottery and porcelain. When both the poultices and steam sterilization were applied together, the resin was removed within twenty-four hours, without physical work using a swab.

Reactive oxygen species can be generated in the skin by hair dyeing. The aim of this study was to find out the effects of the oxidative-type hair dye application in young women on the antioxidant systems. We investigated the lipid peroxide levels, glutathione (GSH) levels, and the antioxidant enzyme activities including superoxide dismutase (SOD), glutathione peroxidase (GSHPx) in plasma and erythrocytes and catalase (CAT) in erythrocytes, and DNA damages in lymphocytes. Also, plasma concentrations of antioxidant vitamins, vitamin A and E, were measured and the correlations between various antioxidant parameters and oxidative damages were evaluated The antioxidant enzyme activities in plasma (GSHPx) and in erythrocytes (SOD and CAT) were decreased significantly after hair dyeing. 1be lipid peroxide and GSH levels were not affected in both plasma and erythrocytes. No significant difference was found in the concentrations of both vitamin A and E between before and after hair dyeing. However, DNA damages expressed as the tail extent moment (TEM) and tail length (TL) were significantly (p<0.001) increased. The plasma vitamin E concentration was correlated with DNA damages (TEM: r=-0.590, p<0.01 and TL: r=-0.533. p<0.01) and RBC SOD activity (r=0.570, p<0.05). In turn, RBC SOD activity was significantly correlated with both plasma MDA levels (r=-0.412, p<0.05) and DNA damages (TM: r=-0.546, p<0.01, TL: r=-0.493, p<0.01). Our results demonstrated that the exposure to hair dyeing produced lymphocyte DNA damage and modification of the antioxidant enzyme activities. Also, there were very strong associations between plasma vitamin E concentration, RBC SOD activity and DNA damage induced by hair dyeing. It suggests that the antioxidant status of a subject is likely to be related to the extent of the harmful effects caused by hair dyeing.

Occupying the center of architecture, design, painting and culture, minimalism is aesthetics of essence that reflects modern age but transcends age at the same time. Pursuing minimalist trend like this and covering the range of furniture, interior and architecture, total designer Antonio Citterio is developing minimalist designs of his own. Called one of the 3 greatest furniture designers in the world today, he leads the trend and enjoys high reputation as a world-renowned interior designer and architect. Therefore, the purpose of this study is to analyze and integrate minimalist descriptive characteristics which appeared in interior space of Citterio who pursues minimalist design. As a study method, this study reorganized minimalism from methodological perspective, drew out expressive characteristics of minimalist interior spaces unique to Citterio based on background and influence of Citterio's design and, centering on this frame of analysis, analyzed and integrated interior spaces he designed. The results of this study are as follows; first, in order to overcome problems that can become monotonous in a minimalist space, Citterio provides spatial experiences to feel visual and spatial variations using the ramp and bridge. Second, he created various senses of space with visual and spatial expansion using transparency in the walls made of glass. Third, with linear expressions, he designed modern spaces with beauty of proportion and balance through contrast and emphasis. Fourth, he made constructive expression through exposure of structures or stairs in the space. Fifth, he created sophisticated atmosphere with contrast between natural and artificial materials and emphasis of material properties. Sixth, his design also shows the characteristic of using furniture as the role of adjusting overall atmosphere of interior space, not as separated parts from it. The author hopes that above results of this study will provide new implications for the development of domestic interior design.
