This study was done in order to investigate the effect of choˇkda~m-t'ang on hyperlipidemia. Methods: Hyperlipidemia was induced in male rats by oral administration of cholesterol(50㎎/㎏) diet for 45 days. To carry out an experiment, the rats was divided into three groups. The first group(normal group) was fed on water for 45 days. The second group(control group) was administered 5% ethanol instead of water only for first 15 days and subsequently administered cholesterol(50㎎/㎏ p.o) diet with 5% ethanol for the second 15 days and fed on a solution of salt for the last 15 days during total 45 days. The third group(sample group) was administered in the same way with the control group for 30 days and injected choˇkda~m-t'ang extract(100㎎/㎏) for the last 15 days during total 45 days. And measured the levels of serum total cholesterol, serum HDL-cholesterol, serum total lipid, serum triglyceride, serum phospholipid, hepatic lipid peroxide and activity of serum AST·ALT. Results: 1. From fifteenth day, the level of total cholesterol was decreased with the significance in the sample group as compared with the control group. 2. The level of serum HDL-cholesterol was increased in the sample group compared with control group, but did not show significance. 3. The level of serum total lipid was decreased with significance in the sample group as compared with control group. 4. The level of serum triglyceride was decreased with significance in the sample group as compared with control group. 5. The level of serum phospholipid was decreased in the sample group compared with control group, but did not show significance. 6. The level of hepatic lipid peroxide was decreased with significance in the sample group as compared with control group. 7. The activity of serum ALT was decreased with significance in sample group as compared with control group, but that of serum AST was not significance. Conclusion According to above results, it is considered that choˇkda~m-t'ang injection groups have recovering effect on the hyperlipidemia induced by oral cholesterol administration in male rats. This might be suggest that choˇkda~m-t'ang have recovering effect on arteriosclerosis and cerebral vascular accidents. Choˇkda~m-t'ang increase body's capacity of controling abnormal lipid metabolism, it can be used to prevent hyperlipidemia and related diseases.

Forteen well-trained male cyclists were used to determine the changes of blood component by ingestion fatty acid diet. Trials consisted of a cycling ride for 120min on the rollers by the ingestion of either 15% of fatty acid diet(n=7) and 30% of fatty acid diet(n=7) during 16 days. Bolld samples were obtained at 0,30,60,90 and 120min and were subsequently analyzed for MCV, RBC, HCT Hb, WBC, HDL-C, NEFA and LA to investgate correlation between blood component. The results were as follows : 1. It was found that there is a significant negative correlation between MCV and RBC, HCT, Hb, WBC(p<0.01) 2. There was a significant positive correlation between RBC and HCT, Hb, WBC, (glucose)(p<0.01), and significant negative correlation with glucose (p<0.05) 3. It was shown that there is a significant positive correlation between HCT and Hb, WBC(p<0.01), and significant negative correlation with glucose (p<0.01) 4. There was a significant positive correlation between WBC and NEFA (p<0.05), significant negative correlation with glucose (p<0.01) 5. It was shown that NEFA is significant positive correlation with HDL-C and LA (p<0.01) By above results, It was suggested that relationship between diet and exercise is diverse due to difference of physiological responses, and that future research is to investigate the correlate relationship applied multi variables.

This study is to analyse the effect of hotel managers’ transformational and transactional leadership on the work satisfaction through distributive, procedural and also the effect of work satisfaction on the organizational citizenship behavior, service quality. Empirical findings show that transformational leadership affect the procedural and transactional leadership, while distributive, procedural leadership affect the work satisfaction. Meanwhile work satisfaction was found affecting the organizational citizenship behavior. Finally the test result showed that transformational leadership did not have significant effect on distributive justice.

The purpose of this study was to investigate effects of different fat contents of diets (15% of total energy and 30% of total energy), which had been supplied to the two groups of cycling subjects for 16 days, on their blood components. During intakes of the experimental fat diet, the subjects had poacticed their fixed and consistent training every day. The blood samples were collected five times from each subject's ante-cubital vein at rest, after 30 min(during exercise), after 60min (during exercise), after 90 min (during exercise), and after 120 min (during exercise). The statistically analyzed results of hematological and biochemical components related to pre- and post- experomental diet intakes and pre- and post- training were summarized as follows: 1. Each of caloric expenditure from two groups with 15% and 30% fat diets demonstrated 3288±177.0kcal and 3563.0±130.0kcal. Each of protein expenditure from two groups(15% and 30%) showed 172.3±22.9g and 179.5±17.1g. Each of fat expenditure from two groups(15% and 30%) illustrated 64.8±9.9g and 120.0±10.5g. Each of carbohydrate expenditure from two groups (15% and 30%) showed 489.3±57.7g and 460.7±44.1g. 2. Both groups who had consistently exercised increased in their weights approximately by 800g after they had been ingested with 15% fat and 30% fat diets for 15 days. 3. Both groups showed the same values(scores) of hematological and biochemical blood components and total fatty acid composition in plasma lipids before and experimental diets (15% of total energy and 30% of total energy) and training for 15 days. 4. The values of RBC, WBC and Hb in the group of 15% fat diet revealed statistically higher increases than those of them in the group of 30% fat diet during exercise (cycling) (P < 0.05). But in process of exercised values of RBC, WBC, Hb and MCV. 5. The values of NEFA in the group of 30% of fat diet were statistically higher than those in the group of 15% fat diet during during exercise (P < 0.05). But in theprocess of exercise time, two groups revealed significantly different values of TG, NEFA, TC, HDL-C.

Radioactive Oxides are formed on the surface of the primary equipment in a nuclear power plant. In orderto remove the oxide film that is formed on the surfaces of the equipment, chemical and physicaldecontamination technologies are used. The disadvantage of traditional technologies is that they producesecondary radioactive wastes. Therefore, in this study, the short-pulsed laser eco-friendly technology was usedin order to reduce production of the secondary radioactive wastes. They were also used to minimize thedamages that were caused on the base material and to remove the contaminated oxide film. The study wascarried out using a Stainless steel 304 specimen that was coated with nickel-ferrite particles. Further, the lasersource was selected with two different wavelengths. Furthermore, the depth of the coating layer was analyzedusing a 3D laser microscope by changing the laser ablation conditions. Based on the analysis, the optimalconditions of ablation were determined using a 1064nm short-pulsed laser ablation technique in order toremove the radioactively contaminated oxide film from the irradiated stainless steel surface.
