In this study, 70 kinds of nutritional composition for five bokkeumbap products(spicy chicken, shrimp(saeu), haemul, nakji, and barbecue bokkeumbap) in high-frequency processed foods were analyzed. Raw data of intake amounts were collected from the 7th Korea National Health and Nutrition Examination Survey. Regarding proximate composition, spicy chicken bokkeumbap had lower water content and higher carbohydrate content than other bokkeumbaps, resulting in the highest total calories. The proximate composition of other bokkeumbaps were all distributed within a similar range. Vitamin content differed according to ingredients added to the bokkeumbaps. Haemul bokkeumbap had high content of vitamins B₁ and B₂, nakji bokkeumbap had high content of vitamin C and β-carotene, and barbecue bokkeumbap had high content of total niacin, folic acid, and vitamin A. For mineral content, barbecue bokkeumbap showed the highest content distribution, while nakji bokkeumbap showed the lowest content distribution. Regarding fatty acid and fat content, the highest content of fatty acids, saturated fats, and trans fats was detected in shrimp(saeu) bokkeumbap. For amino acid content, barbecue bokkeumbap showed highest content distribution. These results can be used as salient basic data for a food nutrient composition database and to significantly contribute to consumers' health.

The personalized meal service is being developed to prevent and alleviate illnesses according to the individual's health condition. However, the current meal does not provide a fully customized service to individuals and a diet that meets the consumer's information needs. The cause is the lack of information on the ingredients and the difficulty of comparative analysis between the materials. Therefore, in this study, we propose basic analysis process for basic information acquisition and database construction for food composition before providing personalized food. In this study, we investigated the content of carbohydrate, reducing sugar and protein as basic components of Grifola frondosa and investigate the content of polyphenol as a biological active ingredients. Respectively. Studies on the hypoglycemic effect of the diabetic rat model have been carried out in relation to the prevention of diseases. Based on the results of this study, it is also possible to obtain information on the basic ingredients of the food and to analyze the information on the content and activity of the biological active ingredients. Using animal models, information on disease prevention and mitigation was also available. The process introduced in this study is applied to various food materials, accumulating data, and utilizing Database, this results will be an excellent tool for providing more efficient service by providing a proper dietary composition for consumers.

The waste rates of 98 food items after pre-preparation were surveyed to provide database for good menu planning. The waste rates turned out 0-64.27% in vegetables, 6.38-7.03% in potatoes, 6.25-68.75% in fishes and shellfishes, 16.61% in eggs, and 16.00-56.84% in fruits. Foods with high waste rates were vegetables, fishes and shellfishes. Survey results were compared with other food composition tables. Foods with 30% higher waste rate than other food composition tables were squash leaf, pacific ocean perch, sweet potato stalk, water cress, green peas, alaska pollack, bluefin tuna, beka squid, crown daisy, dodok, amaranth, beef ribs. Food which waste rates turned out to be decreased by about 30% in this study were corb shell, pomfret, sea mussel, warty sea squirt. For the menu planning, reasonaly exact waste rates for each food items are essential. Since survey results show significant deviations, there should be more studies for exact waste rates for each food.

Objectives: The objective of this study was to develop a zinc database (DB) to estimate the intake levels of zinc in Korean toddlers and preschool children using the data from the Korea National Health and Nutrition Examination Survey (KNHANES). Methods: A total of 3,361 food items for the DB representing the usual diet of Korean toddlers and preschool children were selected based on KNHANES (2009~2013) and the food composition table of Rural Development Administration (RDA). The existing values of zinc in foods were collected from the latest food composition tables of RDA (9th revision) and the US Department of Agriculture (legacy release). The zinc contents were filled preferentially with these collected values. The missing values were replaced with the calculated values or imputed values using the existing values of similar food items from the data source. The zinc intake levels of Korean toddlers and preschool children were estimated using KNHANES and zinc DB Results: A total of 1,188 existing values, 412 calculated values, and 1,727 imputed values were included in the zinc DB. The mean intake levels of zinc for 1-2-year-old children and 3-5-year-olds were 5.17 ± 2.94 mg/day and 6.30 ± 2.84 mg/day, respectively. There was no significant difference in the zinc intake levels between boys and girls in each group. Conclusions: This newly developed zinc DB would be helpful to assess the zinc nutritional status and investigate the association between the zinc intakes and related health concerns in Korean toddlers and preschool children.

This study was reviewed databases and outcomes of national/international off-line and on-line(Internet) nutrition softwares to identify the present conditions of nutrition softwares, and investigated user's needs and determine which component should be included in nutrition software. The most frequently used databases for the national programs were the food composition table provided from the National Rural Living Science Institution in Rural Development Administration and the food composition table and the nutrient contents of foods provided from the Korean Nutrition Society. For international programs, the food composition table from the USDA was commonly used. The analysed outcomes included the degree of obesity, nutrient analysis and nutrient intake compared with RDA, food intake from each by food group, food habits and the frequency of food consumption. As to the result of needs assessment for the Internet nutrition softwares, it was suggested that the needs of the Internet nutrition softwares were high because most of the respondents replied that 3-point('it is needed') or 4-point('it is necessary') on 4-points likert scale. As to the databases, the needs of 'food composition analysis' and 'the suggestion of the Korean RDA' were high. For the basic information for foods, the respondents replied that 'the classification of foods', 'foods codes', 'the amount of ingredients' and 'nutrient analysis' should be included. The needs of 'nutrient analysis of meal', 'diet therapy' and 'meal plan by caloric requirements' were high. As for utilizing the Internet meal planning programs, the respondents replied that 'it should be easy to use' most and demand for 'data saving and the saved data should be usable later' and 'meal planning education tools' were high. In conclusion, the Internet nutrition software that satisfies various needs of users should be developed for policy making that promote public health, nutritional care and self-supporting of foods.

This study was carried out to prepare a copper database of Korean foods which can be used in calculating copper intake from dietary data, and to evaluate the copper nutritional status of Koran adults living in rural areas by dietary intake and serum copper concentrations. A copper database for 1,176 Korean foods was constructed (1) by analysing 112 Korean foods which are frequently consumed by Korean adults living in rural areas, (2) by adapting values form food composition databases from other countries-320 items from the University of Minnesota database, 201 items from the USAD database, and 25 items from U.K. database, and (3) by imputing values from similar foods for 518 food items. Copper intake of 2,034 Korean adults over the age of 30 living in Yeonchongun was Kyunggi province, Korea was estimated by 24-hour recall method. Mean daily copper intake of subjects was 0.98mg. Mean daily intake level of males was 1.11mg which was significantly higher than that of females, 0.88mg. There was a significant difference in the distribution of subjects by the level of copper intake and sex(p<0.05). Mean serum copper concentration was 14.8umol/1 and the percentage of subjects with low, adequate, and high levels of copper concentration were 23.9%, 69.4%, and 6.6%, respectively. The two food groups which contributed most to the dietary copper intake of subjects were cereals and grain products, and vegetables, supplying 46.2% and 12.7% of total copper intake, respectively. Individuallym, rice contributed most, suppling 31% of total copper intake, followed by soybean curd, starch vermicle, barley, etc. Plant foods contributed to 82.1% of the total copper intake. In summary, results of this study show that copper intake of Korean adults living in rural areas is low, and that dietary sources of copper are mainly plant foods. Serum levels of copper in the subjects were relatively normal. The copper database for Korean foods constructed in present study will be a valuable tool for the as-yet limited assessment of copper intake of Koreans. Such studies will contribute to the establishment of a dietary of a dietary allowance of copper and the relationship of copper nutriture and chronic diseases in Koreans.

Microbiological method using a 96-well microplate reader for folate assay was established, and folate intake and blood folate concentrations of 23 female college students were assessed. To evaluate folate intake, dietary data were collected by a 3-day weight food record, and serum and RBC folate concentrations were measured by the new method. The coefficient of variation for the new method was less than 10%. Mean daily folate intake of the subjects was 126.7${\mu}g$ which is only 50.7% of the RDA. The mean concentrations of serum and RBC folate were 7.46ng/ml and 294.4ng/ml, respectively, which were within the normal range. These results indicate that folate intake seems to be underestimated due to incomplete food composition database. Therefore, folate database should be appropriately in order to asses folate intake accurately.

The purpose of this study is to computerize all the necessary information on the daily food value and nutritional status for individuals and groups. In this research, a FOCUS-16jXT (16 bit personal computer ) compatible with IBM-PCjXT was used, and the database files and programs were created by using the dBASEIII package. The food life evaluation system consists of 3 subsystems of Reference, Nutrition Status Assessment and Food Source. The findings are summerized a8 follows: 1. Reference: This subsystem enables users to proceed to the next step, if necessary, by describing each subsystem. 2. Nutrition Status Assessment. 1) Food Habit Assessment: This subsystem determines whether the user has a good food habit or not, based on the answers for ten questions about daily food life. 2) Obesity Assessment: This subsystem calculates Broca index, which is used as a indicator of obesity. 3) Nutrient Intakes: When personal data such as age, sex, weight, height and food consumptions are input, it is possible to calculate the followings. i) Comparison between the amounts intaked and the recommended dietary daily allowances of various nutrients ii) Nutrient intakes from each food group and their composition rates for the nutrients iii) Nutrient intakes per unit body surface area iv) Composition of lipid intake 3. Food Sources: The appropriate food sources for the lacking nutrients will be recommended to the subjects.
