All the parts of lotus, including the seed, rhizome, leaf, stalk, petal, anther, pericarp, and fruit receptacle, have been used in traditional medicine system as a health beneficial supplement. However the most usually used from lotus plant is only the root. Therefore in this study, it will be discussed more the utilization of other parts of the lotus, namely the flower of lotus. The petals and stamens of lotus actually are also rich in bioactive components such as flavonoids and alkaloids, are used in the treatment of tissue inflammation, cancer, skin disease, and also for us as antidotes. One of the biotechnological process that can be used to improve the nutritional content, sensory, and also antioxidant activities is fermentation process. The final product desired from the fermentation process in this study is vinegar. The microbial strain powder used is Uinkin fermented powder with three variations of fermentation. The variations given in this study were initial sugar 32%, 24%, and 14% with the same fermentation temperature, $35^{\circ}C$ for 3 months. The results obtained showed that the pH value and sugar content of products during the fermentation process were decreasing during the fermentation process, with total polyphenol content of $283.7{\pm}97.6mg/100g\;QAE$, and total flavonoid content of $3.3{\pm}0.0mg/100g\;QAE$. For the DPPH radical scavenging ability of the fermentation product also increased in a concentration dependent manner, with ORAC activity of the product showed a high activity of $20.7{\pm}0.41{\mu}M$ TE. Therefore, fermentation process can be the one of method for improving the product. The efficiency of lotus flower vinegar fermentation can be reached with an initial sugar condition of 25% (sample B).

The present study was performed to assess nutritional status of thiamin in 104 elementary school children, living in rural areas of Chungbuk. Dietary intake was obtained by 24 hour recall method and blood was collected to analyze the transketolase activity in erythrocytes. Average dietary intake of thiamin was found to be adequate (1.l5mg, 109.2％ of RDA), even though dietary intake of energy was not more than 1,719kcal, 81.5％ of RDA. Transketolase activity in erythrocytes was distributed in the range of 0.294-0.744mU/mgHb and the mean value was 0.540mU/mgHb. The mean value of TPP effect was 7.9％ and the range was 0-77.4％. It appeared that 7.7％ of children were deficient in thiamin, severely or marginally. There were no significant correlations between transketolase activity and dietary thiamin intake, and between TPP effect and dietary thiamin intake. Mean DVS (Dietary variety score) of the children was 14.2${\pm}$3.2 and DVS was apparently correlated with thiamin intake.

Antioxidant-rich oils were extracted from different parts of sea buckthorn berry with supercritical $CO_2$ (SC-$CO_2$) and n-hexane. The functional components were analyzed and the extracts were screened for their potential as radical scavengers in 1,1-diphenyl-2-picrylhydrazyl radical (DPPH), 2,2'-azinobis-3-ethylbenzotiazoline-6-sulphonic acid (ABTS), galvinoxyl systems. Minor differences were found in fatty acid composition of oils extracted by the two methods. Seed oil contains the highest content of tocopherols while pulp oil and whole berry oil possessed higher concentration of carotenoids. Whole berry oil, pulp oil, and seed oil extracted by SC-$CO_2$ showed 91.7, 90.9, and 93.5% radical scavenging activity (RSA) at 6 mg/mL towards DPPH and 74.3, 54.3, and 74.8% towards galvanoxyl radical at 10 mg/mL. The hexane-extracted oils showed similar scavenging ability. However, the oils obtained by hexane showed significantly higher RSA (p<0.05) than those obtained by SC-$CO_2$ while whole berry oil has the highest RSA towards ABTS among 3 oil samples.

This study compared the nutritional composition and antioxidative activities of different parts (aerial part and root) of Taraxacum coreanum and Taraxacum officinale. To identify the nutrient composition of different parts of Daedelion species, nutrient contents were analyzed. Crude ash, protein, and fat contents of T. coreanum and T. officinale were higher in the aerial part compared to the root. There was no significant difference in crude ash, protein, or carbohydrate content of the aerial part depending on the Daedelion species. Aerial part contents of vitamin A, E, and C were significantly higher in T. coreanum than T. officinale. The K content of the aerial part of T. coreanum and T. officinale was highest, although there was no significant difference among Daedelion species. Contents of oxalic acid, citric acid, and acetic acid in the aerial part of T. coreanum were highest. Contents of total polyphenols, total flavonoids, and DPPH radical scavenging activity of the aerial part were significantly higher in T. coreanum than T. officinale. In conclusion, the aerial part of T. coreanum and T. officinale could be used as antioxidative functional food sources.

Nutritional factors regulating the morphological differentiation and physiological differentiation of Streptomyces exfoliatus SMF13 on surface cultures were evaluated. S. exfoliatus SMF13 produced leupeptin and chymotrypsin-like protease (CTP) at the stage of substrate mycelium growth, and leupeptin-inactivating enzyme (LIE) and trypsin-like protease (TLP) at the stage of aerial mycelium growth. The activity of leupeptin and CTP was high in the region of active growing substrate mycelium, whereas the activity of LIE and TLP was high in the region of aerial mycelium or spores. The differentiations were induced in glucose-limited conditions or by the addition of glucose anti-metabolite (methyl $\alpha$-glucopyranoside), but repressed by high concentrations of glucose or casamino acids. Morphological differentiation (formation of aerial mycelia and spores) was closely related with physiological differentiation (formation of brown-pigment, LIE and TLP). The local distribution of leupeptin, CTP, LIE, and TLP in a developing colony showed that colony development correlated with the production and functions of the compounds: CTP is essential for providing a nitrogen source for mycelium growth: leupeptin regulates TLP activity: LIE inactivates leupeptin: TLP hydrolyzes nongrowing mycelium.

본 연구는 국립산림과학원에서 음나무 신품종으로 개발한 청산, 청송, 청순1 등 3개 신품종을 대상으로 새순의 영양성분 분석, 생리활성 물질분석 및 항산화활성 분석을 통하여 식품학적 가치의 확인과 기능성 소재로서의 개발 가능성을 모색하고자 하였다. 3개의 품종에 대하여 일반성분은 탄수화물과 단백질 함량이 높게 나타났으며 무기성분에서는 칼륨, 칼슘, 마그네슘 순으로 높게 나타났으나 그 차이는 미비했다. 유리아미노산 분석에서는 청산, 청송, 청순1에서 각각 26, 25, 28개의 아미노산을 분석하였으며, 각각 6, 6, 7개의 필수 아미노산을 분석하였다. 기능성 분석을 위한 총폴리페놀 함량에서는 청산 품종이, 총플라보노이드 함량에서는 청송 품종이 높게 나타났다. DPPH 자유라디컬을 이용한 항산화활성 분석에서는 100 ppm에서 청산과 청송의 70% 에탄올과 물추출물의 활성이 높게 나타났다. ABTS 라디컬을 이용한 항산화활성 분석에서는 500 ppm에서 청순1의 70% 에탄올 추출물과 청산, 청송의 물 추출물의 활성이 높게 나타났다. 본 결과로 청산, 청송의 경우 항산화활성이 우수한 기능성과 동시에 가시가 없거나 적은 형태적 특성을 활용할 수 있을 것으로 판단되어지며, 청순1의 경우 단맛을 나타내는 아미노산의 함량이 높아 음나무 고유의 쓴맛과 동시에 단맛이 나는 맛 특성을 활용할 수 있을 것으로 판단되어진다.

This study was carried out to investigate the dietary attitudes and nutritional status of preschool children in different income levels in Busan. The survey was conducted from November 1 to November 30, 2004 by questionnaires mid data analyzed by the SPSS program. The results are summarized as follows: The Kaup index of the upper income class group was higher than that of the other income classes. In the middle income class group, nutrition knowledge scores were higher than in any other income class. Sixty-four point nine percent of the upper income class children, 25.7% of the middle income class children and 15.7% of the low income class children had nutrition education experiences. Intake of protein was higher than that of the Korean recommended dietary allowances (RDAs) for children. In the upper income class group, intake of calcium was higher than in any other income class. Intakes of calcium and iron were lower than those of the RDAs in all children. Dietary attitude had positive correlation with frequency of breakfast, time for outdoor activity, and height and weight, and had negative correlation with frequency of fast food and time for watching television. Frequency of snack had positive correlation with frequency of fast food and time for watching television, but frequency of breakfast had negative correlation with those. These results indicate that nutrition education programs linking parents to children should be carried out to improve their nutritional status.

Not all individuals respond identically, or at times in the same direction, to dietary interventions. These inconsistencies likely arise because of diet and genomic interactions (nutrigenomics effects). A host of factors may influence the response to bioactive food components including specific polymorphisms (nutrigenetic effect), DNA methylation patterns and other epigenomic factors (nutritional epigenomic effects), capacity to induce anuo. suppress specific mRNA expression and patterns (nutritional transcriptomics), the occurrence and activity of proteins (proteomic effects), and/or the dose and temporal changes in cellular small molecular weight compounds will not only provide clues about specificity in response to food components, but assist in the identification of surrogate tissues and biomarkers that can predict a response. While this 'discovery' phase is critical for defining mechanisms and targets, and thus those who will benefit most from intervention, its true usefulness depends on moving this understanding into 'development' (interventions for better prevention, detection, diagnosis, and treatment) and a 'delivery' phase where information is provided to those most in need. It is incumbent on those involved with food and nutrition to embrace the 'omics' that relate to nutrition when considering not only the nutritional value of foods and their food components, but also when addressing acceptability and safety. The future of 'Nutrigenomics and Health Promotion' depends on the ability of the scientific community to identity appropriate biomarkers and susceptibility variants, effective communications about the merits of such undertakings with the health care community and with consumers, and doing all of this within a responsible bioethical framework.

Changes in nutritional and health status brought on by a two-year balanced diet were assessed with anthropometric measurements as well as hematological and lipid profiles in 56 healthy young men. Recommended dietary allowances (RDA) were adjusted with estimated daily weighted activity factor. The weighted resting energy expenditure factor of the subjects was 2.37 $\pm$ 0.05. Compared with RDA, all nutrient intakes were adequate and 56% of energy was supplied by carbohydrates, 18% by protein and 26% by fat. The vitamin and mineral intakes except vitamin B-2 were higher (26.46-129.88%) than RDA. Vitamin B-2 intake was 92.15 \ulcorner 14.16% of RDA. There was no seasonal variation on nutrient intakes. Height was increased and systolic blood pressure was decreased by balanced diet for two years. Body weight, diastolic blood pressure and body mass index (BMI) were unchanged. The level of hemoglobin and hematocrit was not changed, the level of plasma protein was decreased and the level of plasma total cholesterol and albumin was increased. These results suggest that a balanced diet can increase height and complement health status achieved through vigorous exercise, even in adults, and that the level of Korean RDA for energy is adequate to maintain existing body weight.

This study investigated whether social and psychological factors were related to nutritional status of the elderly. Food habits, social contacts and psychological the test score were collected from 86 institutionalized elderly women aged 65-96 in Chon-buk area. Social health status was measured by score of social contacts with others. Depression, self-esteem and locus of control were measured to evaluate psychological health status by using Zung DSI(Depression Status Intentory), Rosenberg SES(Self-esteem scale) and Rotter's vs external control, respectively. Social contacts of the total subjects were lowered, and in the group of over 85, contacts with relatives were significantly decreased compare to under 85 years of age groups. Psychological health status such as depression and self-esteem were also lowered, but locus of control showed internal control that indicates positive attitude to eating behavior. Most of the nutrients intake were positively correlated to self-esteem scores(p<0.05), but not to nutritional risk index score. Intake of vitamin C was related to social health status as well as psychological health status. Increasing the number of contact with relatives, intakes of carbohydrates, fiber, vit B1, vit C, Ca and P were elevated(p<0.05). As the score of self-esteem increased, intakes of fiber, Fe, vit B1, niacin, vit C, and vit A were increased. It is suggested that social activity and health education programs will be needed to improve the nutritional status of the institutionalized elderly.
