of the recipes and 'stir frying' in 76.8% of the recipes. Other cooking methods were used as follows; 'blanching'(24.2%), 'roasting'(22.6%), 'pan frying'(21.0%), 'deep fat frying'(18.7%), etc. The use of 'Boiling' increased significantly(p=0.044) from 4.5% in 2008 to 10.0% in 2010 while the use of 'deep fat frying' decreased significantly(p=0.027) from 21.8% to 10.9%. The frequency of using cooking tools was as follows; knives and cutting boards(100.0%), dishes(92.9%), frypans(91.3%), chopsticks(40.3%), spoons(38.7%), etc. The foods used in cooking were as follows; rice(100.0%), carrots(67.1%), onions(61.9%), eggs(41.6%), paprika(27.7%), kimchi(25.2%), pizza-cheese(22.9%), etc. Natural and processed foods were used in cooking as the ratio of 80:20 approximately. Of the 5 food groups, 'meat fish egg bean' decreased from $24.44{\pm}13.27%$ in 2008 to $20.84{\pm}10.59%$ in 2010, but 'vegetables' increased from $44.38{\pm}15.65%$ to $50.64{\pm}14.07%$ significantly(p<0.05). In conclusion, 5th and 6th graders had an ability to select various foods for their health when cooking even if they have some foods they don't like while they lacked cooking skills such as using various cutting methods and proper cooking tools.

Food habits and Korean food utilization patterns were surveyed from 188 Koreans residing in New Zealand and Malaysia by using a questionnaire. Forty seven percent of the respondents answered that Korean food should be succeeded as its traditional form. Most subjects had strong pride for Korean traditional food. Kimchi was the most frequently consumed side dish followed by Chigaes (stew), broiled meat, Tubu (bean curd), broiled fish, Tangs (soup), and Noodles. While Kimchies were prepared by the respondents themselves, Doenjang and Kochujang were sent from the relatives in Korea or purchased from the market. The changes in food consumption pattern after emigration depended on the availability of food items in residing country. Korean style meal (cooked rice and side dishes) was eaten by 51% respondents for breakfast and by 78.2% for supper. Ramyon was the most frequently consumed instant food. Eating out frequency was much higher in the residents in Malaysia than the ones in New Zealand. This study showed that Koreans residing in foreign countries have the consciousness trying to succeed Korean traditional food culture, and their food consumption pattern partly depends on food availability and socio-cultural properties of the residing country.

The purpose of this study was to analyze the characteristics of menu items offered for school meals in the Daegu and Gyeongbuk area. A total of 538 menu items were collected from six schools (two elementary schools, two middle schools, and two high schools). There was a significant difference in food costs according to menu groups (p<0.001), with the highest food costs for meat and fish dishes (881.66 won) and the lowest cost for kimchi (114.50 won). The proportion of menu items using processed foods and with low operational efficiency were significantly higher in middle schools (p<0.01). In addition, menu items containing animal products were significantly higher in the non-traditional menu items in middle schools (p<0.001). Traditional menu items were less frequently cooked with oil (p<0.001) and processed foods (p<0.001), and their operational efficiency was higher (p<0.001). In conclusion, we found that traditional menu items in school meals were being offered with healthier ingredients and cooking methods, as well as a more efficient foodservice management, than non-traditional menu items.

This study was conducted to examine the levels of total and organic mercury in the scalp hair of the elementary school children and adults, and their relationship with the consumption pattern of fishes and shellfishes. The scalp hair samples were collected from the occipital part of 115 children and 131 adults in costal, urban and rural areas of Kyungpook province from June to August 1991. The mercury content was analysed by the atomic absorption spectrophotometer (model IL. 555) with atomic vapor accessory (model IL. 440). The total and organic mercury contents of hair were significantly higher (p<0.01) among the children who prefer fish and/or shellfish (7.728 ppm, 6.610 ppm), and canned fish and/or fish pastes (6.969 ppm, 5.885 ppm) than those who prefer meat (4.822 ppm, 3.905 ppm) and vegetables (3.974 ppm, 3.224 ppm). The children who prefer to eat the canned fish without cooking showed a higher mercury content than the children who prefer to eat it as stew or mixed with vegetables (p<0.01). There was a dose-response relationship between the intake frequency of canned fish, raw fish and cooked fish and the content of total and organic mercury of hair, the children who eat fish almost everyday showed 2 times higher than those who eat rarely (p<0.01). The mercury content in the hair of the children who eat raw fish was significantly higher than that of the children who eat boiled or broiled fish (p<0.01). The total and organic mercury contents of adult scalp hair increased with age up to the forties and slightly decreased in the fifties. The mercury contents of those who were engaged in the fishery and raw fish restaurant were 2 times higher than those of the farmers. The mercury content of the persons who were favorite dishes of fish and shellfish were most high, and who prefer raw fish were 2 times higher than those of the persons who prefer vegetables and broiled fish. The contents of total and organic mercury in adult scalp hair showed also a increasing tendency with the intake frequency of raw and cooked fish.

Purpose: The aim of this study was to evaluate the dietary behaviors of preschoolers in Daejeon using the Nutrition Quotient for Preschoolers (NQ-P). Methods: The study subjects were recruited from child-care centers and kindergartens located in Daedeok-gu, Daejeon between August and September 2018. A total of 411 preschoolers aged 3 ~ 6 years were included in the data analyses. A questionnaire of NQ-P, which consisted of 14 checklist items on dietary behaviors, was completed by the parents or guardians of the study subjects. The NQ-P scores and its three factors, including "balance", "moderation", and "environment" factors, were calculated according to sex, age, and weight status. Differences in the NQ-P scores and their factors according to sex, age, and weight status were tested using a student's t-test. Results: The mean NQ-P score of the total subjects was $58.5{\pm}9.2$, which was within the medium-low grade. The NQ-P score was $58.5{\pm}9.4$ in boys and $58.6{\pm}9.0$ in girls (p = 0.955). The NQ-P score was similar regardless of the age groups ($57.8{\pm}9.4$ in 3 ~ 4 years vs. $59.2{\pm}9.0$ in 5 ~ 6 years, p = 0.124), whereas subjects aged 5 ~ 6 years showed a significantly higher scores of environment factors than those aged 3 ~ 4 years ($67.9{\pm}16.8$ vs. $61.7{\pm}17.3$). The mean score of the moderation factor was lower in the overweight/obese children compared to the non-overweight/obese children ($46.6{\pm}13.3$ vs. $51.0{\pm}16.2$, p = 0.012). Compared to children aged 3 ~ 4 years, children aged 5 ~ 6 years had higher intakes of vegetable dishes and processed meat. The overweight/obese group showed a higher consumption of processed beverages than the non-overweight/obese group. Conclusion: The current study indicates that the dietary behaviors of preschoolers residing in Daejeon need to be improved. These findings suggest that nutrition education or health interventions targeting young children is necessary for improving their nutritional health status.
