This study was performed to investigate the relationships among personality preferences, dietary habit and nutrient intake of University students (n=283). Mean dietary habit score was similar between sexes and was 46.1/100 in male students and 45.1/100 in female students. Average energy intake of male students was 2,019 kcal (80.8% of RDA) and that of female students was 1,675 kcal (83.7%). Male students were taking less than 90% of RDA in calcium and vitamin $B_2$ and female students were taking less than 90% of RDA in calcium, iron, vitamin C, and vitamin A. Students preferring Judgment had significantly higher dietary habit score than students preferring Perception. Extraversion had higher nutrient intake than Introversion both in male and female students. Male students preferring Feeling had also higher nutrient intake than students preferring Thinking. Nutrient density per 1,000 kcal was higher in Thinking and Judgment than Feeling and Perception. In conclusion, students preferring Judgment and Extraversion have better dietary habit and nutrient intake than those preferring Perception and Introversion. More studies are necessary between personality preferences and dietary behavior to contribute to effective nutrition education and counseling.

This study was performed to investigate the characteristics of nutrient intake according to metabolic syndrome in Korean elderly. Data on 1,200 elderly (men 545, women 655) over 65 years was obtained from the Korea National Health and Nutrition Examination Survey 2010. The subjects were divided into metabolic syndrome (MetS) and normal groups based on NCEP-ATP III guidelines and by applying the Asia-Pacific definition with waist circumference. The prevalence of MetS was 48.9% in all subjects, 35.6% in men and 58.9% in women, respectively. All nutrient intake was significantly lower in MetS than normal subjects, except iron, vitamin A, carotene, and retinol. In the carbohydrate: protein: fat (C:P:F) ratio, MetS showed a higher rate for carbohydrate, but a lower rate for protein and fat than normal. MetS was lower in calcium, vitamin B1, and vitamin C by the nutrient adequacy ratio than normal. Mean adequacy ratio of MetS (0.69) was lower than that of the normal group (0.72). These results demonstrated that undernutrition, not excess intake of specific nutrients - energy, fat, or cholesterol was associated with the risk for MetS in Korean elderly with MetS. Therefore, it is recommended to have a healthy dietary pattern with diverse nutrients for the prevention of MetS.

The aim of this study researchs status of the nutrient intake between male and female students and the nutrient intake by BMI. This study was done to investigate the body composition and nutrient intakes of 340 college students (170 males, 170 females) in Gyeonggi area. Weight, height, BMI, and blood pressure of these college students were measured Nutrient intake was assessed using the 24-hour recall method, and then calculated using the nutritional evaluation program [CAN Pro 2.0 professional (Korean Nutrition Society, 2002)]. Average height and weight were 176$\pm$5.1 cm, 70.60$\pm$l.l kg in male students and 162.2/$\pm$4.5 cm, 54.4$\pm$7.7 kg in female students respectively. Subjects were divided into three groups by BMI: underweight (less than 18.5), normal weight (18.5 to less than 23), and overweight (more than 23). The ratios of male and female subjects among these groups were 5.3% and 17.6% in underweight, 50% and 65.3% in normal weight, and 44.7% and 17.2% in overweight. Systolic and diastolic blood pressures were 124.0$\pm$1.5 mmHg and 76.1$\pm$14.8 mmHg in males and 1l0.l$\pm$12.9 mmHg and 70.l$\pm$10.8 mmHg in females, all in the normal range. Using nutrient values of the 7th Recommended Dietary Allowanes, the nutrient intake was calculated to Korean RDA (%). Nutrients below 75% Korean RDA were Calcium, Vitamin $B_2$, and Folate and nutrients above 100% RDA were Protein, Fe, Phosphorous, and Vitamin $B_6$. BMI showed positive correlations with body fat (%)(p<0.01) and WHR (p<0.01). Nutritional education is desirable for the improvement of dietary behaviors, body composition and nutrient intake of college students.

To develop sweet persimmon bread, the proper ratio of the sweet persimmon powder substituted for strong flour was decided. When 5%,10%,15% and 20% of sweet persimmon powder was substituted as much amount of strong How, the ratio of moisture absorption and loaf volume decreased while its weight increased. The contents of vitamin A,9-carotene and vitamin C increased as the substitute ratio of sweet persimmon powder increased. In color values, as sweet persimmon powder was added more, L and b values decreased and a value increased in the crust while in the crumb bread L value decreased and a, b values increased. In the sensory evaluation, the bread added with 10% persimmon powder was preferred to control in flavor, texture and overall acceptability but not in appearance.

Purpose: This study was performed to evaluate the utilization of a current national Food Composition Database (FCDB) and to investigate demand for nutrients that should be added or supplemented in order to expand the national FCDB. Methods: Surveys were constructed based on the utilization of FCDB, use of a food and nutrition analysis program, utilization and importance of nutritional ingredients, and nutritional ingredients desired to be supplemented in the national FCDB. Self-administered surveys were obtained from 349 food and nutrition specialists, including dietitians, nutrition teachers, food industry workers, professors, and researcher. Results: Exactly 73.6% of respondents used the FCDB, and 90.5% experienced using various food and nutrition analysis programs. Professors and researchers frequently utilized protein, carbohydrate, and lipid nutrients in the FCDB. Among vitamins, vitamin C, vitamin A, and vitamin D were frequently used. Among minerals, sodium and calcium were highly used. Among the subjects, 17.4% of subjects have used phytochemical DB. Carotenoids, anthocyanins, and isoflavones among phytochemicals were frequently used, in that order. Respondents desired an additional data on sugars, vitamin D, folic acid, selenium, iodine, dietary fiber, vitamin $B_{12}$, and carotenoids in the FCDB. Conclusion: The survey results indicate that the current FCDB is actively used for various purposes, although it is necessary to construct a national nutrition database with additional nutrients.

The objective of this work was to investigate the nutritional requirements for the growth of Actinomyces sp. 9RCC5 isolated from the rumen of a native goat in Korea. The growth of strain 9RCC5 on the basal medium or the medium minus certain ingredients from the basal medium demonstrated that strain 9RCC5 showed absolute requirement of vitamin B complex mixture, while hemin and volatile fatty acids (VFA) were stimulatory to growth to some extent. The 9RCC5 strain grew well with casein hydrolysate as the sole added nitrogen source. However, neither a complex of 18 amino acids nor ammonium sulfate effectively replaced casein hydrolysate. Vitamins such as riboflavin and pantothenate were essential for growth, while thiamin and biotin were stimulatory. With regard to VFA, the growth was stimulated by acetic acid but inhibited by valeric acid. Relatively large quantities of $Na^+$, $K^+$ and $Ca^{2+}$ were absolutely required for growth. Supplementation of clarified rumen fluid to the basal medium in a range of 0-10% (vol/vol) resulted in an increased rate of growth as well as an increased extent of growth.

Pantothenic acid and biotin contents in Panax Ginseng roots were determined microbiologically with L. arabinosus 17-5. Detection of the vitamins was achieved by the thin-layer chromatography and PPC. Pantothenic acid and biotin were found at the Rf values of 0.42 and 0.55 respectively on the thin-layer chromatograms. In order to find out whether or not the L. arabinosus growth promoting factors contained in the respective ginseng extracts, as shown by the microbiological assay, were really the vitamins respectively, PPC was carried out. Microbiological assay of the vitamins met with results that the average pantothenic acid content in the roots was 6.6r/g, calculated as Ca-pantothenate, and the average biotin content 9.24 mr/g.

The nutritional evaluation, and antimutagenic and anticancer effects of Kimchi were reviewed. Kimchi contains high levels of vitamins including vitamin C, $\beta$-carotene, vitamin B complex, niacin, and of minerals such as calcium, potassium, iron and phosphorous, etc. Kimchi is a low energy food, byt contains high quantities oforganic acids, dietary fiber and lactic acid bacteria in addition to the vitamins and minerals. Thus Kimchi could be developed as a protective food as it contains the various regulatory nutrients. The levels of NO3, NO2 and nitrosamines in Kimchi ingredients and Kimchi during theripening are not significant. However, high level of NaCl that could be used when prepared Kimchi in the warm region can be a problem, since high concentraitons of NaCl(>9.5%) in Kimchi could be comutagenic to themutagen of MNNG. The methanol extract of Kimchi, red pepper powder, garlic and lactic bacteria revealed antimutagenic or anticancer activities. The Kimchi extract also inhibited the growth of various human cancer cells.
