The purpose of this study was to analyze the quality of meal and dietary habits of college students according to where they reside. This survey included 260 students and was conducted through questionnaires. The subjects were divided into three groups: first group was composed of students who reside in boarding-houses(BH group, N=72), second was students who reside in self-boarding set up(SB group, N=90), and third was those who lived in the same house with their parents(HWP group, N=98). The average age of the students in the BH, SB, and HWP group were 19.7 yrs, 21.1 yrs, and 21.7 yrs, respectively. There were no significant differences in the weight, height and BMI among the three groups. The BH group had significantly higher frequency of skipping breakfast and smoking than those of the SB and HWP groups. The amount of energy, food, carbohydrates, proteins, fats, vitamins and minerals consumed in the BH group were significantly higher than in the SB and HWP groups. Similarly, the NAR(nutrient adequacy ratio), MAR (mean adequacy ratio), ND(nutrient density) and INQ(index of nutritional quality) of the BH group were significantly higher than those in the SB and HWP groups. There was no significant difference in the KDDS(Korean's Diet Diversity Score) between the three groups. From the data obtained, the SB and HWP students appeared to have more dietary problems than the BH students. These results show that nutrition education for SB and HWP students is needed in order for them to learn proper dietary management and help improve the diet of students living in self-boarding arrangements.

This study was to analyzed the quality of the meal and the level of nutritional intake in female college students according to the place of residence in female college students. This survey was conducted through questionnaire was given to 359 female students. The subjects were divided into two groups : one group was comprised of those the students who resided in a self-boarding house(SB group, n=245), and the other group comprised of was the student those who resided in the same house with their parents(HWP group, n=114). The mean age of the subjects were 21.6 years old(SB) and 20.6 years old(HWP)(p<0.05). The average height, weight and BMI were 161.8 cm, 57.9 kg, $20.3kg/m^2$ in the SB group and 161.9 cm, 53.4 kg, $20.3kg/m^2$ in HWP group, respectively. The SB group had significantly higher frequency of skipping breakfast and alcohol drinking consumption than the HWP group. There was no significant differences in the mean daily energy intakes between the SB and the HWP groups. However, the plant protein(p<0.01), carbohydrate (p<0.05), vitamin $B_1$(p<0.01), vitamin $B_2$(p<0.05), vitamin C(p<0.01), plant calcium(p<0.01) and potassium(p<0.05) intakes were significantly lower in the SB group were lower than the intakes in the HWP group significantly. And in addition, the cereals(p<0.05) and fruits(p<0.001) intakes in the SB group were significantly lower than the intakes in the HWP group. There was no significant differences in the KDDS and DVS between the two groups, but there was a decreasing trending downward. For that reason, the SB students seemed appeared to have more dietary problems than the HWP students. These results suggest that nutritional education for SB students are is needed in order to supply the lack of management capability on the proper help improve the diet of students living in independently life.

The present study examined the effects of soybean-derived phosphatidylserine (SB-PS) on the learning and memory function and the neural activity in rats with trimethyltin (TMT)-induced memory deficits. The cognitive improving efficacy of SB-PS on the amnesic rats, which was induced by TMT, was investigated by assessing the Morris water maze test and by performing cholineacetyl transferase (ChAT), acetylcholinesterase (AChE) and cAMP responsive element binding protein (CREB) immunohistochemistry. A positron emission tomography (PET) scanning the rat brain was by performed administer 18F-Fluorodeoxy-glucose (18F-FDG). The rats with TMT injection showed impaired learning and memory of the tasks and treatment with SB-PS produced a significant improvement of the escape latency to find the platform in the Morris water maze at the 2nd day compared to that of the MCT group. In the retention test, the SB-PS group showed increased time spent around the platform compared to that of the MCT group. Consistent with the behavioral data, SB-PS 50 group significantly alleviated the loss of acetyl cholinergic neurons in the hippocampus compared to that of the MCT group. Treatment with SB-PS significantly increased the CREB positive neurons in the hippocampus as compared to that of the MCT group. In addition, SB-PS groups increased the glucose uptake in the hippocampus and SB-PS 50 group increased the glucose uptake in the frontal lobe, as compared to that of the MCT group. These results suggest that SB-PS may be useful for improving the cognitive function via regulation of cholinergic marker enzyme activity and neural activity.

This study examined the effect of dietary lipids and guar gum on lipid metabolism in ovariectomized rats. The experimental animals received ovarietomy (OVX). Lipids sources were divided into 3 groups (soybean oil(SB), beef tallow(BT)) and fish oil(FO)) and guar gum was supplemented to each lipid diet (SBG, BTG, FOG). Experimental diets were fed to therats for 16 weeks. Serum triglyceride (TG) levels were higher in the BT group and lower in the FO group as compared to the SB group .Serum total cholesterol (Tc) and HDL-C levels were lower in the FO group as compared to the SB group. Serum LDL-C and phospholipid levels were lower in the FO group as compared to the SB group. Serum lipids levels were lowered by guar gum supplement. Serum SFA(saturated fatty acids) contents were not significantly influenced by dietary lipids and guar gum. Serum MUFA(monounsaturated fatty acids) contents were the lowest in the SB group. Fecal weight was highest in the beef tallow group and lowest in the fish oil group. Fecal weight was increased by guar gum supplement in all lipid groups. Total bile acid content in feces was increased by guar gum supplement in the soybean oil and beef tallow groups. The endothelial cells of the beef tallow group changed from a flat shape to distorted round and enlarged shapes. The subendothelial layer was the thickness the thickest in the beef tallow group ; the interspace between elastic lamina was widened and elastic lamina was straightened and partly disrupted . The fish oil group showed more porminient endothelial cells and subendothelial layer. Internal elastic membrane and elastic lamina exhibited regularly wavy shapes. Guar gum supplement showed positive effects in all lipids groups. Based on the above results , it is suggested that beef tallow increased serum TG levels and injured the wall of the aorta. On the other hand, fish oil , which decreased serum lipid levels, has a positive effect on the walls of the aorta. Guar gum protects the aorta from injury by reducing the serum lipid levels. Therefore, it is suggested that soybean oil and beef tallow consumed with guar gum is beneficial.

This study was conducted to investigate the supplementary effects of Suwon 464 developed by Rural Development Administration, which has over two times of dietary fiber content compared with normal rice (Ilpum), on lipid metabolism in diabetic mice. We supplied 5 kinds of experimental diets (com starch diet as a control (CO), Ilpum polished rice diet (IP), Ilpum brown rice diet (IB), polished rice diet (SP) and brown rice diet (SB) of Suwon 464) to diabetic mice for 8 weeks, after analyzing dietary fiber contents of 5 experimental diets. Diet intake, body weight, organ weights, and lipids levels of serum, liver and feces were measured. The dietary fiber contents in CO, IP, IB, SP, and SB diets were 1.0, 1.2, l.4, 1.4, and 2.0% respectively. Body weight and liver and epididymal fat pad weights were lower in SB group than the other groups though there was no significant difference in diet intake among experimental groups. The concentrations of serum triglyceride was lower in SP and SB groups than CO and IP groups. The levels of hepatic total lipid and total cholesterol were significantly lower in SP and SB groups than CO group, and the level of hepatic triglyceride was lower in IB, SP and SB groups than CO group. The levels of total lipid and triglyceride excreted in feces were higher in IB, SP and SB, and the level of total cholesterol in feces was higher in SP and SB groups than CO group. These results suggested that the high dietary fiber rice (Suwon 464) decrease the triglyceride or total cholesterol concentrations of serum and liver by increasing of fecal lipid excretion in diabetic mice.

Safflower (Carthamus tinctorius L.) seeds have long been clinically used in Korea to promote bone formation and prevent osteoporosis. In addition, the safflower buds (SB) were found to have more useful functional ingredients than safflower seed. Thus, we investigated the preventive effects of SB diet in ovariectomized (OVX) rats. The rats were divided into five groups; sham operated group, OVX alone group, OVX plus 17β-estradiol (E₂ 10 μg/kg, i.p.) and OVX plus SB diet feeding group (0.3% or 1%). Feeding of SB diet (0.3% or 3%) to OVX rats markedly increased trabecular formation in femur compared to OVX rats. Feeding of SB diet (0.3% or 3%) to OVX rats also decreased TRAP activity compared to OVX rats. These results suggest that SB diets have bone sparing effects by the decrease of osteoclast activity. We also observed that OVX rats fed with SB diet (0.3% or 3%) exhibited the decrease of calcium and phosphorus in serum compared to OVX-induced rats. Therefore, SB may be beneficial for the patients of osteoporosis, especially in postmenopausal women.

In order to investigate the effect of Samulbyulgapchoengpitang(SB) and one herb added(SBA) on anti-tumor and immune response, the author performed this experimental study, Tumor weight(TW), mean survival days(MSD) and body weight(BW) in vivo, natural killer cell activity(NKCA). rosette forming cells(RFC), phagoctic activity in recticuloendomethrial system(PA), delayed type hypersensitivity(DTH), hemoagglutinin titer(HA) and hemolysine(HL) in vitro were measured in mice. 1. MSD was prolonged in both of treated groups(SB and SBA) as compared with control group. 2. TW was decreased in both of treated groups with statistical significance as compared with control group. 3. BW was increased in both of treated groups and just only in SB with statistical significance as compared with control group. 4. DTH was increased in both of treated groups with statistical significance as compared with control group. 5. HA was increased in both of treated groups with statistical significance as compared with control group. 6. HL was increased in both of treated groups with statistical significance as compared with control group. 7. RFC was increased in both of treated groups and just only in SB with statistical significance as compared with control group. 8. NKCA was increased in both of treated groups with statistical significance as compared with control group. 9. PA was increased in both of treated groups with statistical significance as compared with control group. According to the above experimental results, it is suggested that SB and SBA will have anti-tumor substance and enhance the effect of immune response. But we have to consider the longtime prescription of SBA because there have been no experiments in its side effect or accumulation in body.

Behavior of platinum group elements during crystallization within ore magma is of interest. In this study platinum is selected and its mineralogical and geochemical behavior in the presence of antimony and tellurium is investigated at 600$^{\circ}C$. High purity Pt, Sb, and Te are used as starting material and silica quartz tubings are as container. Rection products have been examined by use of ore microscope, X-ray diffractometer, electron microprobe analyser and micro-indentation hardness tester. stable phases at 600$^{\circ}C$ are platinum (Pt), Pt5Sb, Pt3Sb, PtSb, stumpflite (PtSb), geversite (PtSb), PtTe, Pt3Te4, Pt2Te3, moncheite (PtTe2), tellurantimony (Sb2Te3), and antimony (Sb). Geversite is the mineral showing the most significant extent of solid solution by up to 27 at% between Sb and Te elements. Isothermal section of 600$^{\circ}C$ is established in this study. It is noted that platinum cannot coexists with stumpflite or geversite under equilibrium condition, and stumpflite composition in equilibrium with geversite may be used as geothermometer.
