This is to study the effects of the program of group art therapeuties for the low-income bracket children's melancholy and uneasiness. The experimental group is 19 children at their option of all 38 children in P child center at J city, Jeonbuk. The program has been going on after-school hours program at the facilities at 16times from May. 4 to August. 17, 2007. I have made the before-medium-after examination the COD, RCMAS and K-MFF through Repeated Measures ANOVA. The result is as follows, The melancholy of experimental group in comparison with that of control group is reduced by control group 0.42 and experimental group 2.67. And in lower rank group, the melancholy of experimental group for control group is dropped in the same way. In uneasiness, by the decrease of control group 0.10, experimental group 0.33, the uneasiness of experimental group for that of control group is decreased. In all drive, the drive of experimental group for that of control group is decreased by control group 0.12 and experimental group 0.33. And similarly, in all lower field, the drive of experimental group is reduced for that of control group. It is through our help to learn the proper way that they express their experience before the group members, listen to another person's story with attention, recognize their own and other's emotion, and are aware of feeling and action.

This study was done to determine the effect of antioxidants added perilla oil diet on the content of cholesterol, vitamin E, and lipid peroxide in serum and tissue of rats. Four groups of experimental diets, such none added perilla oil diet, ascorbic acid added perilla oil diet, vitamin E added perilla oil diet, EDTA added perilla oil diet were fed ad libitum to the 4 weeks white male rats of Sprague-Dawley strain. The results obtained are summarized as follow: 1) The body weight gain in all experimental diet groups was higher than the control gorup and EDTA added diet group was lower than the other experimental diet group, while food intake in vitamin E added diet group was the highest and vitamin C added diet group was the lowest in the control group. 2) Total cholesterol levels in serum of all experimental diet groups were lower than that of the control group and especially the level of total cholesterol in none added diet group and vitamin C added diet group were significantly lower than that of control group. 3) HDL-cholesterol levels of all experimental diet groups were lower than that of the control group and especially none added diet group was significantly lower than that of control group. 4) The activities of glutamic oxaloacetic transaminase (GOT) in serum of all experimental diet group except EDTA added diet group were higher than that of the control group and especially none added diet group was significanly higher than that of the control group. The activites of glutamic pyruvic transaminase (GPT) in serum of all experimental diet groups except vitamin C added group were higher than that of control group. 5) Vitamin E levels in serum of none added diet group and vitamin C added diet group were lower than that of the control group and vitamin E added diet group and EDTA added diet group were higher than that of the control group. 6) Vitamin E levels in liver of all experimental diet groups were higher than that of control group and especially none added diet group and vitamin E added diet group were significantly higher than that of the control group. 7) Lipid peroxide in serum of all experimental diet group were lower than that of control group and especially EDTA added diet group. 8) Lipid peroxide in liver and spleen of all experimental diet groups were higher than that of the control group and lipid peroxide in kidney of all experimental diet groups except EDTA added diet group were higher than that of the control group. Four these results, as vitamin C, vitamin E and EDTA added diets have an effect to lipid peroxide by antioxidants, it could be suggested that perilla oil diet has required to add antioxidant because it has not sufficient vitamin E for antioxidant and intake and overtake level of perilla oil diet should be studied to go ahead.

This study investigated hepatic functional improvement and anti-fibrotic effects of water extracts of black tea. Male Sprague-Dawley rats were divided into four groups (normal, control, and two experimental subgroups: Ba, Bb) and observed for 3 weeks. Liver fibrosis in rats developed from carbon tetrachloride ($CCl_4$) administration, except for the normal group. Except for the normal and control group, the two experimental subgroups were fed water extracts of black tea. The food efficiency ratio significantly increased in the experimental group compared to the control group. The experimental group had a significantly lower liver weight compared to the control group. The ratio of liver weight to body weight was significantly lower in the experimental group than the control group. The levels of aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, blood urea nitrogen, and low-density lipoprotein-cholesterol in serum significantly decreased in the experimental group compared to the control group. The values of hydroxyproline and malondialdehyde in liver were even lower in the experimental group than the control group. In observations on liver histology, weaker inflammation and fibrosis were observed in the experimental group compared to the control group. In conclusion, water extracts of black tea help hepatic cells keep their functions, restraining and protecting the liver from impairments caused by $CCl_4$ administration, and can be effective as anti-fibrotic agents.

Purpose: This study was to evaluate the effects of foot reflexology on blood pressure, serum lipids level and life satisfaction in essential hypertension patients. Method: The research design used was a nonequivalent control group pretest-posttest design. Foot Reflexology was used as the experimental treatment from June 23rd, 2003 until August 31st, 2003. Thirty-four subjects were assigned to an experimental group(18) and control group(16). Foot Reflexology was administered twice a week for 6 weeks and self foot Reflexology was administered twice a week for 4 weeks on the experimental group. Result: There was a significant decrease in systolic blood pressure but no significant decrease indiastolic pressure in the experimental group compared to the control group. The total cholesterol level in the experimental group compared to the control group was not significantly decreased after foot reflexology. However, the triglyceride level in theexperimental group compared to the control group was significantly decreased after foot reflexology. On the other hand, high density lipoprotein and low density lipoprotein levels in the experimental group compared to the control group was not significantly decreased after foot reflexology. Life satisfaction in the experimental group compared to the control group was significantly improved after foot reflexology. Conclusion: The results proved that foot reflexology was an effective nursing intervention to decrease systolic pressure, and triglyceride but not for the blood cholesterol and to improve life satisfaction. Therefore, blood cholesterol should be further evaluated in a larger group of subjects and for a longer period. Further research is regarded as necessary to evaluate and to compareeffects of self-foot reflexology and foot reflexology.

The physical properties of seven sizes of control groups and experimental group in stainless steel orthodontic wires were studied in tension, hardness, bending, torsion and observation of microstructure. The wires (0.40-0.90mm dia.) of round type were tested in the as-received condition. The wires of control groups were TRU-CHROME and REMANIUM, and experimental group was SK wire which was developed by ourselves and made in Korea. The results were as follows; 1. The chemical compositions of control groups and experimental group were austenite stainless steel wires of SOS 304. 2. Higher values of tensile and yield strength in tension were control group I, experimental group, control group II. Maximum tensile and yield strength of experimental group were $203.63{\pm}1.41kg/mm^2$ in 0.70mm diameter and $148.96{\pm}4.88kg/mm^2$ in 0.60mm diameter, and maximum elongation was $5.20{\pm}0.57%$ in 0.45mm diameter. 3. Hardness values of experimental group were similar to control groups. Maximum hardness values were $596.2{\pm}13.66Hv$ in 0.45mm diameter wire of control group I, $590.5{\pm}20.08Hv$ in 0.50mm diameter wire of control group II, and $563.6{\pm}5.35Hv$ in 0.70mm diameter wire of experimental group. 4. Torsion properties of experimental group were similar to control group I and more than control group II. Maximum torsion cycles were $31.8{\pm}2.48$ in 0.45mm diameter of control group I, $17.4{\pm}4.84$ in 0.60mm diameter of control group II, and $24.6{\pm}3.04$ in 0.45mm diameter of experimental group. 5. Maximum bending cycles of experimental group were smaller than control groups. Maximum bending cycles were $9.00{\pm}0.00$ in 0.50mm diameter wire of control group I, $10.0{\pm}0.82$ in 0.40mm diameter wire of control group II, and $8.0{\pm}1.26$ in 0.50mm diameter wire of experimental group. 6. Microstructures of experimental and control groups co-existed with martensited austenite structure and elongated austenite structure. 7. The direction of wire fracture was propagated parallel to torsion direction typically and there was no probability showing wire fracture at inclusions and surface scratches. 8. The type of wire fracture was brittle fracture at initiation site and ductile fracture at core.
