Since 1959 ${\beta}-aminoethylphosphonic$ acid was discovered in the living organism, the biosynthesis and biological functions of aminophosphonic acids have been extensively studied. The author designed and carried out this study for 14 weeks to find out the metabolic function of Ethylaminophosphonic acid (AEP) and it's utilization in the living body. Sixty rats, thirty males and thirty females aged $40{\pm}5$ days were divided into two parts, one for alanine supplemented as control group and the other for AEP as experimental group to compare metabolic pathway of ordinary amino acid with that of AEP. Both alamine and AEP group were divived into two subgroups according to the level of supplements, 0.1% and 0.2% of the diet. The major components of the diet in this study were composed of 20% casein, 72% Sugar, 4% fat, 4% salt Mixture, and all kind of Uitamins in adeguate amount. For comparision of biological values between experimental and control group in terms of body weight, uninary nitrogen, creatinine excretion and final orgam weight, there were no statically significant difference in these respects. This meant AEP could be utilized in the body as much as alanine could. Urinary phosphorus excretion was determined by developing the blue color to read on the Spectronic 20. Statistically insignificance in the urinary phosphorus excretion between experimental and control group was observed in spite of the supplementation of phosphorus of AEP for experimental group in the diet. The level of blood phosphorus was higher in experimental group than that in control group this result supported above result. In the analysis of fat and nitrogen contents in the liver, AEP group showed slightly higher than control in both respects. But it was noteworthy 0.2% AEP group in both sex were higher than 0.1% AEP in liver fat content. Histological examinal of internal organs liiver, lung, spleen, heart, kindey, adrenal and sex organs showed no changes in all groups included in this study. The group supplemented higher level of diet. by alanine 0.2% and AEP 0.2% stayed on less body weight gain and lower liver weight. This result could be interpreted that amino acid imbalanced condition was arose in the body.

This study was projected to get basic data which can provide a basis for future direction in nutritional education, and also to find the way how to improve the nutritional supply by evaluating the current nutritional intake of average high school students through the survey study of their daily packed lunch. Five hundred twenty seven students from two boys high school and two girls high school including one general and one vocational school respectively were chosen as random sampling technique. Four hundred forty nine among the 527 students had brought lunch. The contents of lunch box were weighed and converted into nutritional values according to the food composition table and compared with recommended dietary allowances. The results compared and classified by sex, School and housewives' educational level were as follows: 1. The nutritional supply in the lunch box was 671 Cal of energy and 22.3 gm of protein for male students which were respectively 55.9% and 74.2% of the dietary recommendations. On the other side female student's lunch boxes were found to contain 495 Cal of energy and 21.3gm of protein which are respectively 61.8% and 80% of the dietary prescriptions. Excluding niacin, all vitamins and minerals were found to be short. 2. Calorie intake in the vocational high school was found to be higher than in the general high school but lower in protein intake especially significant difference (P<0.01) in animal protein. 3. From the nutritional point of view the educational backgrouud of the housewives was not found to have any influence in the way of preparing the lunch boxes. 4. Nutrients of lunch box were heavily inclined to grain rather than to side dishes.

Four domestic frying oils (soybean, corn, rapeseed and rice bran oil) were studied on their changing properties according to thermal oxidation by means of chemical analysis of their compositions and measurements of various physical and chemical properties. The content of linoleic acid which is an essential unsaturated fatty acid and the total amount of unsaturated fatty acids were highest in soybean oil (53.2% and 80.3% respectively) among the unheated frying oils and the degree of its thermal degradation was lowest during the continuous heating period for 48 hours at $180^{\circ}C$. However in general, the contents of unsaturated fatty acids were sharply decreased by thermal oxidation whereas the saturated fatty acid contents ranging 10-17% were not changed considerably, which largely agreed with the results of iodine value measurements. The free acid and peroxide values were also lowest in soybean oil (0.09 and 5.6 respectively) among the unheated oils whereas an anomalously high free acid value was observed in rapeseed oil (54.8) which was packed in unleveled glass bottles. Such a high value is probably ascribed to the photo-catalyzed oxidation during storage. The viscosity measurements have shown similar values before heating, but after thermal oxidation for 32 hours the rapeseed and rice bran oils became too thick to measure viscosity by capillary flow method with heavy darkening in color.

This study qualitatively and quantitatively analyzed various carotenoids, L-ascorbic acid, and tocopherol and their anti-oxidant properties from four varieties (Special, Chelsea, Cupra, and Fiesta) and three different color stages [green (GP), yellow (YP) and red (RP)] of paprika harvested in Korea. Seven carotenoids were identified, mainly lutein in GP (Special: 4.65${\pm}$0.84 mg/kg fresh weight (fw)) and YP (Fiesta: 5.19${\pm}$0.05 mg/kg fw), and capsorubin (3.16${\pm}$0.35 mg/kg fw) and capsanthin (53.70${\pm}$6.23 mg/kg fw) in Special of RP. RP was the highest in total carotenoids, L-ascorbic acid, and ${\alpha}$-tocopherol contents, while GP was the highest in ${\gamma}$-tocopherol content. RP showed the strongest antioxidant activity ($IC_{50}$=62.40${\pm}$0.03 ${\mu}g/mL$ in an ABTS assay and 182.77${\pm}$31.74 ${\mu}g/mL$ in a DPPH assay). Paprika in different color stages has many phytochemicals even though they have different kinds of carotenoids. Therefore, dietary intake of paprika may be helpful for improving human health.

This study was attempted to investigate the effect of fermentation of soybean on protein and mineral bioavailability. The traditional, oriental fermented soybean foods, Meju and Tempeh, and isolated soybean protein( ISP ) and cooked soybean were prepared and fed to rats as sources of protein. The C-PERs of ISP, cooked soybean, Meju and Tempeh were 1.82, 1.98, 2.11, and 2.36, respectively C-PERs of fermented soybean products, Meju and Tempeh were higher than ISP and cooked soybeans. However, they were not significantly different The percent retention of protein of rats fed with casein, ISP, cooked soybean, Meju and Tempeh were 47.44%, 51.83%, 47.67%, 50.90% and 45.97%, respectively, showing no significant differences among the diets. The rates of calcium retention percent were 62.26%, 59.22%, 61.59%, 55.78% and 67.09 % in rats fed with casein, ISP, cooked soybean, Meju and Tempeh, respectively, demonstrating no significant differences. Rats fed with cooked soybeans did show significantly higher iron retention rate than other samples. However, this study failed to any significant increase in iron availability. The percent of fine retained in rats fed with ISP was significantly lower than those of rats fed with other diets, however, significantly high amounts of zinc were retained in rats fed with Tempeh compared with other diets. The percents of zinc, iron, calcium retained in the bones of rats were not significantly different among the diets.

This study was conducted to investigate the level of total serum cholesterol, triacylglycerol(TG), and phospholipid(PL) and the ratio of serum lipoprotein fractions of rats fed various types and amounts of fats for 12 weeks. Male weaning rats were fed one of four semipurified diets: control diet supplied 12% of calories as fat(polyunsaturated fatty acid:saturated fatty acid, 2 : 1), low fat diet supplied 3% of calories as fat(polyunsaturated fatty acid: saturated fatty acid, 2 : 1), 45%-corn oil diet supplied 45% calories from corn oil, and 45%-butter fat diet supplied 45% calories from butter fat. The level of total cholesterol in serum was increased in rats of 45%-butter fat diet group for the experimental period from 4 to 12 weeks, in rats fed 45%-corn oil diet from 8 to 12 weeks, but low fat diet group(3%-fat diet) is not different for all experimental period, compared with rats of control group(12%-fat diet). The level of TG in serum was also increased in rats fed 45%-butter fat diet for the entire experimental periods and in rats of low fat diet and 45%-corn oil diet groups at 12 weeks only, compared with control diet group. Specially TG in serum of rats fed low fat diet was remarkably increased at 12 weeks. After 12 weeks the level of PL in serum of rats fed low fat diet was lower than other diet groups. ${\alpha}$-Lipoprotein portion of lipoprotein fraction in serum was lower in rats fed 45%-butter fat diet at 4,8 and 12 weeks and rats fed low fat diet at 12 weeks, compared with control diet group and ${\beta}$-lipoprotein portion was reversely increased. Among them the ratio of lipoprotein fraction in rats fed low fat diet for 12 weeks was most significantly different.

The purpose for this study was to investigate the health status according to the age and BMI by interviewing male workers in their twenties and thirties in the Daegu Gyeongbuk region. The body measurement was assessed by height, weight, BMI, body circumference (waist, hip), waist-hip ratio and body fat mass. The health status has been analyzed and assessed as normal group, health concerned group and health suspected groups. Weight, percent ideal body weight (PIBW), BMI and body circumference (waist, hip) and waist-hip ratio was proven higher according to the order of obese group, overweight group and normal group. Waist-hip ratio was proved to be higher in the thirties group than the twenties. Body fat mass was higher in the obese, overweight and normal groups. In the concerns of health status, the ratio of health concerned group and health suspected group increased according to the increase of BMI. Blood pressure (SBP, DBP) was higher in the obese group than in the normal group and overweight groups, and blood glucose was higher in the thirties than in the twenties. SGOT, SGPT, ${\gamma}-GTP$ has been proven higher in the obese group than in the normal group and overweight group, ${\gamma}-GTP$ was higher in the thirties than in the twenties. Investigating the correlation of the anthropometric characteristics and biochemical characteristics, the heavy weight resulted in heavier BMI, PIBW, body circumference (waist, hip), waist-hip ratio and higher body fat mass. Blood pressure (SBP, DBP), total cholesterol, blood glucose, SGOT, SGPT and ${\gamma}-GTP$ all became higher according to these influences. In conclusion, male workers have to recognize that health status becomes worse and possibilities of chronic disease prevalence rate increases according to aging and the increase of BMI. Accordingly, it is necessary to make an effort to prevent chronic diseases.

This study was conducted to isolate strain for the preparation of fermented antler (Cervus cornu parvum) and evaluate its physiological activities. The growth degrees of twenty-one samples from Bacillus sp., Lactobacillius sp. and mushroom strain on antler extract agar were evaluated in this study, and Bacillus subtilis KH-15, SCB-3, Cordyceps militaris, Phellinus linteus, Inonotus obliquus 26136, and Inonotus obliquus 26147 were selected. The fermented antler extract by C. militaris had relatively higher contents of total sugar (1619.3 ${\mu}g$/mL), uronic acid (302.0 ${\mu}g$/mL), sulfated-glycosaminoglycan (S-GAGs) (119.9 ${\mu}g$/mL) and sialic acid (21.6 ${\mu}g$/mL) than any other extracts. The anti-complementary activities of all fermented antler extracts were higher than non-fermented antler extract, and among these samples, fermented antler extract by C. militaris showed the highest anti-complementary activity (inhibition of 50% total complement hemolysis, $ITCH_{50}$; 50.1% at 1,000 ${\mu}g$/mL). The ability of fermented antler extract by B. subtilis KH-15 to scavenge 2,2-azino-bis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical ($IC_{50}$; 4.97 mg/mL) was significantly the highest (p<0.05), whereas the extract from I. obliquus exerted significantly (p<0.05) high 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity ($IC_{50}$; 16.98 mg/mL) among all samples. The results of this study suggest that physiological effects including immuno-modulating and antioxidant activities of the antler may be increased through fermentation process.

Rubus coreanus Miquel (RCM) has been used as one of the Korean traditional medicines for prostate health. In addition, recent studies have reported that RCM reduced chronic inflammatory diseases such as cancer, and rheumatoid arthritis. Therefore, in this study, we investigated the effects of unripe and ripe RCM on inflammationrelated gene expressions in LPS-stimulated mouse peritoneal macrophages. Mice were fed with 2% unripe RCM (U2), 10% unripe RCM (U10), 2% ripe RCM (R2), and 10% ripe RCM (R10) for 8 weeks. Peritoneal macrophages were isolated and stimulated with LPS then proinflammatory mediators (TNF-${\alpha}$, IL-$1{\beta}$, and IL-6), and prostaglandin E2 ($PGE_2$) productions were assessed. Moreover, gene expression profiles were analyzed by cDNA microarray method. Unripe and ripe RCM significantly reduced TNF-${\alpha}$ production but only unripe RCM decreased IL-$1{\beta}$ and IL-6 production. RCM intake significantly reduced inflammatory-related gene expressions such as arachidonate 5-lipoxygenase, interleukin 11, and nitric oxide synthase 2. Furthermore, unripe and ripe RCM significantly decreased ceruloplasmin, tissue plasminogen activator, thrombospondin 1, and vascular endothelial growth factor A expression which modulates symptoms of chronic inflammatory diseases. RCM intake also significantly increased hypoxia inducible factor 3, alpha which is the negative regulators of hypoxia-inducible gene expression. Furthermore, only unripe RCM reduced chemokine (C-C motif) ligand 8, chemokine (C-X-C motif) ligand 14, and phospholipase A2 expression. In this study, we showed that RCM had anti-inflammatory effects by suppression of pro-inflammatory mediator expressions and may reduce chronic inflammatory disease progress through regulation of gene expressions. These findings suggest that RCM might be used as a potential functional material to reduce chronic inflammatory responses.

According to the records that all the people in our country were taught the way of braiding the hair and hatting in the first year of 'Tangun' (the founding father of the Korean nation) and that the discipline between sovereign and subject, man and woman, and the standard of food, drink and dwelling were originated from that year, it seems that all the people in our country had lived with keeping a certain standard of food, clothing and shelter, and with maintaining the order in life from ancient times. So, our country have been called 'the Eastern Land of Courtesy' and also regarded as 'the country of the true gentle-man' which was characterized as the custom of a humane, and as the country that had the immortality since a benevolent person lived to a great age. Thus, all the people in our country have lived with keeping and maintaining a certain standard of all aspects in life, and the philosophy in life that we have today was established by the influences of our characteristic thought, Confucianism, Buddhism, Taoism and Christianity, especially the life style in the Chosun Dynasty Period have strong influence on our today life. Thus, the contents concerned with the standard of custume life among those of all life in the Chosun Dynasty Period was studied, and clothes itself is unable to give expression to its ends but when the relationship that is, the inter-harmony among clothes, the body which will be dressed in, and the inherent psyche in that body is formed, then the ends, the complete beauty will be expressed. Though there were many studies dealt with clothes itself, no one was concerned with the all kinds of standard in activities that the dresser should keep, so the purpose of this article is that as above. The literature search is used as the research method. The eight books, 'Noneo' (the Analects of Confucius), 'Yeogi' (the Book of Courtesy), 'Sohak' (the book of Precepts for child-ren), 'Yeosaseo'(the Women's Four Books), 'Sasojeol'(Korean Scholars' Minor Principles) 'Eonhaenaehoon' (Private Moral Instructions for Women), 'Woo-am seonsaeng kyenyeoseo' (Master Woo-am's Cautions for Girls) and 'Kyoobangkasa' (the Lyric Lines of the Boudoir) that had influenced the whole field of life in the Chosun Dynasty Period are analyzed, selected and finally arranged for studyilng the foundation of culture of the clothing and for helping to that culture in modern and future life. The results are as follows: 1. The standard of the clothing life in the Chosun Dynasty Period had deeply rooted in the teaching of confucianism, but also had been influenced by the custom which rooted in our people. 2. There is the emphasis upon the trinity among mind, clothes and activities in the clothing life. 3. The clothing and hat have to be dressed symmetrically in full of all required elements, 4. There is the harmony between the clothing with hat and environments or surroundings. 5. The true elegance in the clothing life will be realized not by the exterior outfit but by the interior outfit with the attitude of chastiny. In conclusion, as the material of clothing life in the Chosun Dynasty Period has the characteristics of the simplicity, the cleanliness, the elegance and the refinement, our clothing life is to be mastered with the simplicity, the cleanliness and the elegance in that life and with the harmony between the inside and the outside.
