This paper reports the RFC(Recursive Flow Classification) algorithm that is available on multiple fields. It is easy to be implemented by both software and hardware. For high speed classification of packets, the implementation of RFC is essential by hardware. Hence, in this paper, RFC algorithm is simulated by Verilog-HDL, and it verify the efficiency of the algorithm. The result shows that the algorithm can perform a packet classification within several cycles. It is not only much faster than software implementation but also enough to support OC192c.

Purpose : One of the most difficult problems in the care of children with nephrotic syndrome remains the occurrence of relapses, despite initial response to steroids. Constantinescu reported that rapidity of initial response to steroid therapy could predict fewer relapses in the first year. So we evaluated the changes in serum lipid abnormalities in children with corticosensitive nephrotic syndrome before steroid treatment and the correlation between serum lipid levels and renal function, days to remission. Methods . We analyzed the Medical records of children who were managed by us between October 1994 and August 2000. In 33 patients with corticosensitive nephrotic syndrome, we evaluated the correlation between serum lipid levels and renal function [Creatinine clearance(Ccr)] and proteinuria before steroid treatment, and days to remission defined as the third day when the patient's urine becomes protein free. Results : There were 21 males and 12 females. Median age at presentation was 6.4 years (range: 1.8-17.3 years). Median days to remission were 15.4 days (range 4-42 days) on Prednisolone $60mg/m^2$ daily. The increased levels of triglyceride, total cholesterol, LDL cholesterol, apolipoprotein B, total cholesterol/HDL cholesterol, Lipoprotein(a) were observed. But the level of HDL cholesterol was not increased. Serum albumin was decreased a]id proteinuria was increased before steroid treatment. But Ccr was not decreased. There were negative correlation between serum albumin and total cholesterol (r = -0.5157, P<0.005), LDL cholesterol (r = -0.5543, P<0.005), total cholesterol/HDL cholesterol (r = -0.4506, P<0.01), lipoprotein(a) (r = -0.4570, P<0.025), apolipoprotein B (r = -0.5297, P<0.025), apolipoprotein B/apolipoprotein Al (r = -0.5851, P<0.01), apolipoprotein B/HDL cholesterol (r = -0.4961, P<0.05) before steroid treatment. There was no correlation between proteinuria and serum lipid profiles. Also Ccr and serum lipid profiles were not correlated. There was positive correlation between days to remission and HDL cholesterol (r = +0.4511, P<0.05), apolipoprotein B (r = +0.5190, P<0.05), apolipoprotein B/HDL cholesterol (r = +0.7169, P<0.005). Conclusions : This results reveal that HDL cholesterol, apolipoprotein B and apolipoprotein B/HDL cholesterol can be used as a predictive factor in corticosensitive nephrotic syndrome. We could not determine the significant level of these lipids for insufficient patients number, but these level may predict future relapses of corticosensitive nephrotic syndrome patients and thus may allow to better management and treatment protocols. More data and long term follow up studies should be needed. (J Korean Soc Pediatr Nephrol 2001;5 : 136-46)

The present studies were designed to compare the effects of both dietary fat levels and P / S ratio on lipid components in plasma and tissues. Changes in plasma HDL-cholesterol, cholesterol and TG, and also in tissue cholesterol and TG were determined in young rats fed diets providing total dietary fat as 10%, 25% or 45% of calories and P / S ratio as 0.2 or 4.0. Plasma cholesterol levels were getting higher as dietary fat levels increased at P / S 0.2. Plasma cholesterol was lower in rats fed dietary fat either 25% or 45 %, each with P / S 4.0. But at 10% no change in plasma cholesterol were observed by P / S 4.0 because of a possible insufficiency of the absolute amount of PUFA. HDL-cholesterol was rather less sensitive to the modification of dietary fat level, but was reduced in rats fed diets of P / S 4.0 at either 25% or 45% fat, even though HDL-cholesterol were increased in the group of 10% with P / S 0.2. Total cholesterol per g- liver were significantly increased as dietary fat levels increased. Liver cholesterol levels were higher in rats fed diets of P / S 4.0 at higher fat levels (25% or 45%) which possibly suggested that a reduction of plasma cholesterol by high PUFA diet was not at least from a decreased synthesis of cholesterol in liver. However, in muscle no significant differences were found by feeding high P / S ratio at each levels of fat. At 10% fat level, compared to 25% or 45%, cholesterol level was lower in g-liver but higher in g- muscle. Plasma TG was decreased as more dietary fat were supplied at P / S ratio, but no consistant response obtained at low P / S ratio. TG per g-liver were reduced by feeding P / S 4.0 diet at 10% or 45% fat level but no differences were found in muscle. P / S 4.0 diet was more efficient in lowering plasma cholesterol TG and HDL-cholesterolt levels only if fat level was more than 25% of the total calories And young rats were more resistant to dietary fat modification.

In Med Dept. Daehan Education Insurance, Total 690 cases(male 376 cases, female 314 cases) were inspected to study the change of serum lipid value. The objects of investigation were total cholesterol, HDL cholesterol, triglyceride, phospholipid and total lipid value. The results are as follows: 1) In the normal subjects, with the relation of serum lipid value and the age. triglyceride, phospholipid and total lipid value showed the increasing tendency by 70 age, but total cholesterol value and HDL cholesterol value showed the increasing tendency by 59 age and the decreasing tendency after 59 age. 2) In the normal subject the difference of serum lipid value between sexes did not make the significant difference of level statistically in all items which can be inspected. 3) The weight change and serum lipid value are very significantly related. Total cholesterol, HDL cholesterol and total lipid value are high in female if the weight is light. But they are high in male the weight is heavy phospholipid value is opposite to the above result. Triglyceride value is high in male regardless the weight, but the significant difference happened in the high weight group. 4) As serum lipid value of hypertension patients is compared with that of the normal subjects, HDL cholesterol, triglyceride, phospholipid and total lipid value are significantly high. 5) The doubtful group of the fatty infittration of liver among the hypertension pafients have very significant difference in serum lipid value compared with not only the value of the normal subject but also that of the obesity group. 6) The doubtless group of the fatty infitration of liver among the hypertension patients have the significant difference in all serum lipid value compared with that of the normal subject, but compared with the obesity group males had the significant difference of HDL cholesterol value and both sexes had the significant difference in total lipid value, but had no significant difference in total cholesterol, triglyceride and phosprolipid value. 7) The ratio of total cholesterol per HDL cholesterol had the significant difference in the doubtful hypertension patients of the fatty infittration of liver and the relative weight, but it had no significant difference compared with the normal subject in the doubtless hypertension patients.

For obesity management requires accurate measurement of abdominal fat. The purpose of this study was to find out the correlation between abdominal fat and lipid measured with BIA and CT. Secondly, This study investigate for usefulness of abdominal fat measured by BIA and CT as an obesity index. As a result, TG showed higher value in the overweight obese group than normal group but HDL showed lower value in the overweight obese group than normal group. TG and HDL appeared significantly relationship with by BIA and CT in the normal group. However, in the overweight obese group TG showed significantly relationship with the BIA. According to multiple regression analysis on BMF and TAF was affected by HDL in the normal group. And BMF, %BF was affected by TG in overweight obese group. In conclusion, abdominal fat showed significant correlation with lipid. Abdominal fat measured by BIA and CT to assess obesity index is considered as a useful way to evaluate.

The purpose of this study was to investigate the effect of Lycii fructus on the serum lipid in rats fed high fat diet. We compared the effects of L. fructus and L.fructus water extract both adminstered with high fat diets on rats that had previously been on high fat or standard diets. Two separate experiments were conducted for 6 weeks. respectively. In experiment I, 4 groups of rats were fed experimental diets consisting of either \circled1 6 weeks of a standard diet(control), \circled2 6 weeks of a high-fat diet(HHC), \circled3 3 weeks of a high-fat diet followed by 3 weeks of a high-fat diet containing L. fructus(HHL) or \circled4 6 weeks of a high-fat diet with L. fructus extract in place of water for the last 3 weeks (HHT). In the second set of experiments, a high-fat diet (SHC), high-fat diet containing L.fructus(SHL) or high-fat diet with L. fructus extract in place of water (SHT) were fed for 3 weeks after 3 weeks of standard diet feeding. Rats fed L. fructus diet consumed more diets than high-fat diets. THe results of experiment I showed significant decreases(p<0.05) in serum triglyceride(TB) and low density lipoprotein-cholesterol (LDL-C) levels with L. fructus feedings, but did not show andy changes in total cholesterol (TC) level. High density lipoprotein-cholesterol (HDL-C) level was increased significantly(p<0.05) with L. fructus feedings. Therefore, the ration of LDL-C to HDL-C(LDL-C/HDL-C) which is used as an atherosclerosis index was significantly (p<0.05) low, while the HDL-c/TC ration was significantly(p<0.05) high with L.fructus intake. However, no significant were found in serum cholesterols and TG levels in experimentII. The results of these experiments indicate that , regardless of the feeding from, L. fructus can be beneficial in lowering serum TG and LDL-C levels for habitual high-fat diet intakers. L.fructus also seems to be effective in elevating serum HDL-C level, theregy having beneficial effects on atherosclerosis by influencing the serum lipoprotein profile.

Unlike studies of Europeans and Americans, many epidemiological studies of the Korean population have indicated that their risk for cardiovascular disease does not decrease with a vegetable-rich diet. The different dietary practices of Koreans, who consume salted vegetables instead of fresh vegetables (common in the Western diet), has been suggested as a reason for this observation. Korea is in a period of rapid epidemiologic transition, which includes dietary and disease patterns; therefore, this study investigated differences in the food consumption pattern and blood lipid profiles of Koreans compared to Europeans and Americans. The identification of dietary patterns related to blood lipid abnormalities was carried out using the 2007~2009 Korean National Health and Nutrition Survey data from 14,056 subjects. Dietary patterns were analyzed according to food group and nutrient intake. Blood lipid abnormalities were classified into three groups: hypercholesterolemia, hypertriglyceridemia, and low HDL cholesterolemia (hypo-HDL-cholesterolemia). The prevalence of hypercholesterolemia, hypertriglyceridemia, and hypo-HDL-cholesterolemia was 12.4%, 16.2%, and 27.7% respectively. In our analysis, the low consumption of all food groups was related to hypercholesterolemia. The high consumption of vegetable-containing foods, alcoholic beverages, and the low consumption of milk products were associated with hypertriglyceridemia and hypo-HDL-cholesterolemia. Thus, unlike Europeans and Americans, the low consumption of all food groups is related to hypercholesterolemia and a low consumption of milk products is related to hypertriglyceridemia and hypo-HDL-cholesterolemia. Dietary pattern might play a role in epidemiologic transition of Korean. Also, this study implies necessity of further research using longitudinal data.

Magnesium(Mg) plays an important role in lipid metabolism and Mg deficiency but Ca sufficiency Increases serum cholesterol and triglyceride. The relationships of serum Mg, Ca, Ca/Mg ratio with lipids was examined in 79 female college students in Choong-Nam area. Subjects were divided into underweight, normal and overweight groups according to their BMI. The average age, body weight, height and BMI were 21.9yr, 55.9kg, 158.5cm and 22.62kg/$m^2$ respectively. Height was not different between groups. Serum cholesterol and LDL-cholesterol concentrations were significantly lower in the underweight group than other groups. BMI had positive correlations with LDL-cholesterol, atherogenic index (AI) and LDL-cholesterol/HDL-cholesterol ratio(LPH), and negative correlations with HDL-cholesterol/total cholesterol ratio. Serum minerals (serum Mg, Ca, Ca/Mg ratio) and serum lipid concentrations were not significantly different between groups. However, there was a tendency of increasing serum Mg level with increasing serum HDL-cholestrol, HDL-cholesterol/total cholesterol ratio and decreasing serum LDL-cholesterol, LPH, total cholesterol/HDL-cholesterol ratio(TPH) and AI. And there was a tendency of increasing serum Ca level with increasing serum HDL-cholesterol/total cholesterol ratio and decreasing serum triglyceride, LDL-cholesterol, LPH, TPH and AI. And there was a tendency of increasing serum Ca /Mg ratio level with decreasing triglyceride, serum LDL-cholesterol and TPH. This study was limited within serum levels of minerals (serum Mg, Ca and Ca/Mg ratio), serum lipids concerned with CHD, therefore I hope there will be wider efforts to consider about the dietary levels of minerals for presentation of the connection between dietary Mg, Ca and serum lipids.

Obesity is the risk factor of atherosclerosis and not only increases triglyceride concentration in blood but also decreases relatively the ratio of TG to HDL-Cholesterol in blood. In case of obesity, systolic blood pressure is also increased in responding the increase of TG in blood. Index of obesity in red ginseng-taking group (ginseng group) was lower as compared with non-red ginseng-taking group (control group). The TG concentration, the ratio of triglyceride to HDL-cholesterol in blood and systolic blood pressure were decreased in the subjects of ginseng group compared with that in control group. It is inferred that long-term intake of ginseng products may help to prevent the risk of atherosclerosis and obesity.

The purpose of this study was to compare to the effects of regular exercise on body fat contents and plasma lipid composition of college women. This study was conducted from May to August in 2000. The subjects selected for the experiment were composed sixty three female college students. The basal anthropometric measurements were performed. The levels of total cholesterol, HDL-cholesterol, triglyceride and fatty acid composition of plasma were determined. And plasma glucose concentrations was also assayed. The results obtained are summerized as follows : Average height and weight of E(exercise) group were found to be slightly higher than NE(non exercise) group. The percent of body fat and body fat mass (kg) in E group was slightly lowered than that of NE group. There was decreased on the levels of plasma total cholesterol, triglyceride by regular exercise. HDL-cholesterol level was not significantly different between two groups, but LDL-cholesterol level in E group was significantly lowered than that of NE group. Therefore, plasma total cholesterol and LDL cholesterol levels was significantly decreased by regular exercise.
