In order to study the anti-stress effect of hyangbujapalmultang, several measures of stress, including body weight changes, organ weight changes and catecholamine changes. The following result have been obtained: 1. The weight loss of contol group was $28.5{\pm}1.8g$, that of sample group was $20.3{\pm}1.6g$. This differance was statistcally significant. 2.The organ weight(Liver,Spleen,Kidney,Adrenal gland) was the only significant change in the spleen, in sample group comparing to control group. 3. The norepinephrine contents of control group was $695.5{\pm}22.7pg/ml$, that of sample group was $607.4{\pm}21.7pg/ml$. This shows significant difference in sample group comparing to contol group. 4. The epinephrine contents of control group was $212.8{\pm}9.8pg/ml$, that of sample group was $182.6{\pm}8.4pg/ml$. This shows significant differance in sample group comparing to control group. 5. The dopamine contents of control group was $504.5{\pm}31.3$, that of sample group was $463.4{\pm}27.8pg/ml$. This shows the value decreased, but none of it is significant. Based on avove results, it may be conculed that hyangbujapalmultang has anti-stress effects.

This study was carried out to investigate the status in weight loss yield of edible meat quality and free amino acid contents of the snow crab(Chionoectes japonicus) by steaming and various drying treat-ment. Change of body weight loss in steaming treatment sample were 20.48∼26.72% and yield of edible meat of steaming sample was higher than raw sample(p<0.05) The pH value was increased with steam-ing and drying and pH of trunk meat was more increased than leg meat. Volatile basic nitrogen(VBN) content of vacuum dried sample was highest and VBN of hot-air and freezing dried sample were about 10mg%. Content of vaccum dried sample wre 41.33 and 48,56mg%. Thirty kind of free amino acids dectected in the snow crab and changes of free amino acid in leg meat were markedly reduced by vacuum drying and the reducing ratio of leg meat by freeze drying was little. The major free amino acid of leg and trunk meat were 39.94% 46.78% respectively. The formation of flavor free amino acid in freezing dried sample were high but its hot-air aried sample were small.

In order to study the effects of Pinus densiflora on hyperlipidemia and lipid in rats, we divided the rats into groups(Normal group, Control group and Sample group) and perfomed the experimental research. Hyperlipidemia and lipid in rats were induced by high fat diets for 8weeks. The sample group was administerd the extract of Pinus densiflora for 14 days and control group was administerd equal dose of oral. And then we measured the amount of serum triglyceride, Total cholesterol, LDL-cholesterol, HDL-cholesterol, Free Fatty Acid, phospholipid, Insuline, Laptin, Body weight, epididymis fat weight & rate, epididymis fat cell, Cardiac Risk Factor(CRF). The results were as followers : 1. Sample Group showed decreasing effects on Total cholesterol, Trigylceride, LDL-cholesterol, and Phospholipid levels in serum and CRF significantly. 2. Sample Group showed increasing effects on HDL-cholesterol level in serum significantly. 3. Sample Group showed decreasing effects on Insuline in serum significantly. 4. Sample Group showed increasing effects on Laptin in serum significantly. 5. Sample Group showed decreasing effects on Body weight, epididymis fat weight & rate, epididymis fat cell significantly.

Introduction The effects of Samchulkunbitang on the immunosuppression induced by methotrexate in rats were investigated in this experument. The multiple parameters of immunity assessed in each rats includes the rate of body weight loss, weight changes in thymus, spleen and axillary lymphnode. The number of lymphocytes and CD4+ T cell count in the blood, thymus, spleen and axillary lymphnode were also measured. Methodology Male Sprague-Dawley rats were chosen as an experiment object and were divided into 4 groups by a random selection. Each group consisted of 6 rats. The normal group didn't receive any treatment. The control group was administered with methotrexate for 5 days. The sample Ⅰ group was administered with Samchulkunbitang for 5 days. The sample Ⅱ group was administered with both Samchulkunbitang and methotrexate for 5 days. The dosage of medication was 2cc/day, 1cc given at 10 AM and another 1cc given at 5 PM. Results The rate of body weight loss was significantly increased in the Sample Ⅰ and Sample Ⅱ group. The weight of thymus and spleen were significantly increased in Sample Ⅰ and Sample Ⅱ groups While the weight of axillary lymphnode did not show much increase. No significant differences were measured among the experimental groups. Blood lymphocyte count, blood CD4+ T cell count, spleen lymphocyte count, axillary lymphnode lymphocyte and CD4+ T cell count were significantly increased in Sample Ⅰ and Sample Ⅱ groups while spleen CD4+ T cell count did not show much increase. No significant differences were measured among the experimental groups. Conclusion As one can witness from the above results, administration of Samchulkunbitang played potent role in increasing immune system among the rats treated with methotrexate which induces immunosuppression. Overall increase of lymphocyte count and CD4+ T cell count in the sample groups with Samchulkunbitang effectively proves its ability to boost the immune system.

The pertinent Korean Industrial Standard (KS F) requires that rocks dried at 105 ± 5℃ be taken out of the oven into air and weighed on a scale. However, when rocks are exposed to air after the drying process, they absorb moisture, meaning that their weight will increase. In this study, eight cubic samples of Hwangdeung granite of different sizes were used to measure and compare the dry weight. The dry singularity weight measured in air was smaller than that measured in the drying oven. The difference in dry weight showed a positive correlation with sample size. Conversely, the difference in dry weight per unit weight of rock showed a negative correlation with sample size. The weight of a rock sample exposed to air is determined by the magnitude of the influence of convection currents occurring around the heated rock and the influence of moisture absorption in air. A singularity occurs when the magnitudes of these two effects are equal. The larger the rock sample, the longer the time taken for the singularity to occur, the greater the weight loss of the sample, and the longer the time taken for the sample to return to the initially measured weight on account of the greater moisture absorption for larger samples than smaller samples. In the future, research into the singularity and dry weights measured inside the drying oven will help to identify and address the limitations of the current KS F testing regulations.

The panel survey is need to have a more concern about a response due to a secession and non-response of a sample. And generally a population is not fixed and continuously changed. Thus, the rotation sample design can be used by the method replacing the panel research. This paper is the study of comparison to equal weight method, Duncan weight, Design weight method, weight share method in rotation sample design. More specifically, this paper compared variance estimators about the existing each method for the efficiency comparison, and to compare the precision using the relative efficiency gain by the Coefficient Variance(CV) after getting the design weight from the actual data.

Sodium hyaluronate (NaHA), water soluble polymer having ultra-high molecular weight, is characterized by using on-line frit inlet asymmetrical flow field-flow fractionation (FI-AFlFFF) and multiangle light scattering (MALS). This study demonstrates the capability of power programming FI-AFlFFF for the separation of NaHA and the applicability of FI-AFlFFF with MALS for the characterization of molecular weight distribution and their structural information. Since sample injection and relaxation in FI-AFlFFF are achieved by using hydrodynamic relaxation, separation of high molecular weight polymers can be achieved smoothly without halting the separation flow. Experiments are carried out with the two different NaHA products (a raw NaHA sample and a thermally degraded NaHA product) and molecular weight distribution and conformations in solution are determined. Influence of sample filtration on the change of molecular weight distribution is also discussed.
