Imwonshibyukji was a copying manuscript written around 1825, the 27th year of king Soonjo of the Josun Dynasty. It was a massive home encyclopedia of total 52 books and 100 volumes. The unpublished 'Jeongjoji' of its 17-20th volumes analyzed the cooking methods on the steamed rice and gruel and studied the degree of their usefulness and medical values in the light of the cooking process science. The cooking method on the steamed rice was composed of 14 items, and the general introduction outlined 6 kinds of the rice. These were all quoted from Chinese literatures. The 11 items present the methods on the general production of the rice, 2 on the cooking process, and 1 on the preservation. The main material of the rice was rice, and others were naked barley, prosomillet, foxtail millet, glutinous millet, etc. , and the secondary materials were glutinous rice, small red bean, black soybean, potato, bamboo seed, jujube, taro, gaertner, chestnut powder, persimmon power, julib(Zizania caduciflora), mangcho(Erigeron canadensis), namchok(Nandina domestica), licorice root, nitrous, peach, palmicha(schizandra, jinseng, cheonmoondong(Asparagus), and honey are mixed), etc. The literatures quoted in the rice were all 33, in which 23 were Chinese (69.7%) and 10 were Korean (30.3%). In the case of gruel, the cooking methods on the general gruel were described in 41 items, and on the gruel for a medical treatment were in 48 items, in which there was not a cooking method on the gruel but only its medical values were presented. The materials used for the general gruel were approximately 60 kinds: rice, glutinous rice, munbean, job's tears, rye, soybean, black sesame seed, antler of cervidae, chicken, crucian carp, and various medical materials, etc. The gruel was mainly used for protection and medical treatment, and partly for food for hungry people. The literatures quoted in the gruel were total 57, in which 26 were Korean(45.6%), and 31 were Chinese (54.4%). It can be their characteristics that Almost all of the Chinese literatures on the methods of the steamed rice and gruel do not exist.

Safflower Yangengs were prepared with composite dried powder of small red bean(Phaseolus radiatus L.) containing various ratios of safflower(Carthamus tinctorius L.) seed powder sifted through 20, 35, 45 and 60 mesh size and kinds of mixed water, their cooking characteristics were evaluated. Water content and water activity of cooked products were increased as the content and sieve mesh number of safflower seed powder increasing from 5%, 20 mesh to 20%, 60mesh, respectively. Color values of yangeng were increased in green tea extract mixed water. Rheological properties of yangengs were measured by compression test with texture analyzer, as results, hardness and fracturability increased that were shown in high content and high mesh number sifted safflower seed powder, but adhesiveness and springiness decreased, respectively. From the sensory evaluation test for yangeng, sensory scores were good scores in more mesh number sifted powder addition, especially overall acceptance, texture and fracturability. The 45mesh and 15% powder added yangeng was noted as having high sensory scores and preferable acceptability in sensory evaluation.

This study was peformed to estimate manganese intake and the major food source of manganese in Korean adults. The 354 subjects aged over 20 years were measured anthropometrics and dietary intake using 24-hour recall method. Daily intake and the major food sources of manganese were calculated using manganese database of food composition tables in Korea, USA and Japan. The average age, height, weight and BMI were 54.6years, 165.7cm, 67.2kg and $24.5kg/m^2$ for men and 53.8 years, 153.7cm, 59.1kg and $24.9kg/m^2$ for women, respectively. The daily energy and manganese intake of men were significantly higher than those of women (1740.9 kcal vs. 1432.6 kcal; p<0.001, 3.7mg vs. 3.2mg; p<0.01). However, daily manganese intake per 1000kcal between men and women was not significantly different (2.2mg/1000kcal vs. 2.3mg/1000kcal). Daily manganese intakes from each food group were 1.9mg from cereals, 0.5mg from vegetables, 0.4mg from pulses and 0.2mg from seasonings. The 20 major food sources of dietary manganese were rice, soybean, sorghum, Kimchi, tobu, wheat flour, red pepper powder, small red bean, glutinous millet, soybean paste, potato, Ramyeon, green pepper, noodle, buckwheat Naengmyeon, soybean sprout, laver, watermelon, perilla seeds powder and soy sauce. Manganese intake from these 20 foods was 74.0% of the total dietary manganese intake. In conclusion, daily manganese intake of the subject was 3.4mg (2.2mg/1000 kcal) and met adequate intake of manganese. The mai or food sources of manganese were cereals, pulses, and vegetables such as rice, soybean, sorghum, Kimchi and tobu.

The purpose of this study was to compare the intake status of calcium, phosphorus, iron, and zinc of Korean adults residing in different regions. Subjects were recruited and divided into three groups according to the districts where they lived, which included rural (n=137), coastal (n=100), and urban district (n=117). Subjects were interviewed using a general questionnaire and 24-hour recall method for dietary intake. The average age of the subjects were 58.1 years for rural district, 57.7 years for coastal district, and 48.6 years for urban district. There was no significance in total food intake by regions. The food intakes from cereals, mushrooms, vegetables of rural district, that from fishes of coastal district, and those from sugars, milks, oils of urban area were the highest among three districts. The calcium, phosphorus, iron, and zinc intakes were $60.1\%,\;123.9\%,\;95.2\%,\;and\;73.1\%$ of RDAs, respectively. The calcium intakes as percentage of RDA in rural and coastal district were significantly (p<0.01) lower than that in urban district. A larger number of subjects from coastal or urban district ate under $75\%$ of zinc RDA compared to those from rural village. Major sources of dietary calcium in total subjects were anchovy, kimchi, milk, soybean curd, rice, ice cream, sea mustard, yogurt, loach, and welsh onion. Rice supplied $15.5\%$ for phosphorus, $22.1\%$ for iron, and $35.9\%$ for zinc of total intake. Except for rice, major sources of dietary zinc were pork, beef, small red bean, dog meat, chicken, jacopever, soybean curd, glutinous millet, and kimchi. In conclusion, the food and mineral intakes of adults differed according to the regions in which they resided. The food and nutrient intakes of coastal district were not satisfactory, and calcium and zinc intakes of three regions did not meet RDAs. Therefore, it is required unique and discriminatory nutritional education with each region for increasing intakes of calcium and zinc.
