This research was carried to investigate the food preference of students, from elementary school, middle school, high school, university and industrial workers on Jinju, Sacheon and Jinyang by age and sex. The results were obtained as follows. In case of rice as the stationary food, plain white boiled rice showed the highest preference among all the groups. Most of groups liked most of one-dish meals such as kimbab, fried rice with kimchi, dumplings and bibimbab, especially the elementary school students and middle school students. On the other hand, high percentage of industrial workers disliked the western food such as pizza, hamburger and sphagetti. Most of subjects liked jajangmun, nangmun and bibimgooksu as noodles. As the side dishes generally they prefer the soup to stew. Male prefer the soup with beef and female prefer soup with vegetables. Stew with kimchi and stew with soybean paste showed high preference among most of groups. Most of broil food showed high preference, and students prefer meat to fish as broil cooking materials especially younger students. As a general they liked soybean sprout, spinach and wild sesame leaf as namul cooking method and they liked korean cabbage kimchi, chonggak kimchi, kackdoogi and dongchimi as kimchi. As a dessert subjects liked most of fruits and they liked yoghurt, fruit juice, milk, sikhae and soda as drinks generally. On the other hand snacks such as cooky, candy, cake, corn, rice cake, sweet potato have the lowest percentage preferance as a dessert, but students from elementary schools showed the highest preferance to sweet such as cooky, cake and candy than any other group. These food preferance results showed some nutritional problems especially young age students. They should eat more green-yellow vegetables, liver food and dried small sardine and they should reduce snacks such as candy and cooky and soda drinks. Therefore it is necessary to conduct nutrition education by parents, teachers and dietician together to improve their food habits and their health.

The purpose of this study was to assess the iron nutritional status of college women residing in the Kyungin area. The anthropometric parameters, nutrient intake, and biochemical status of iron were measured for 102 college women. The mean height and weight were 160.3cm and 52.4kg, respectively. The proportion of subjects whose BMI was less than 20 was 41.3%. The proportion of subjects assessed as overweight(25$\geq$25%) assessed by the fat percent(FP) was 53.9%. The mean daily intake of iron was 13.90mg(77.1% of RDA), composed of 0.97mg of heme iron and 12.44mg(69.0% of RDA). When the sources of iron were grouped as rice(including bread), noodle, soup, side dish, and snack, noodle provided, 3.95mg of iron regarded as the highest amount. Subjects were taking 6.72mg(51.4% of RDA) of iron per day from main dishes(rice, bread and noodle). The fifty five percent of the subjects showed iron depletion(serum femitin<20ng/ml)and 33.4% showed suppressed erythropoiesis with iron deficiency(serum ferritin<10ng/ml). The anemic subjects assessed with transferrin saturation (<15%) represented 33.3% of the test population, whereas 11.8% of the subjects possessed less than 12g/dl of hemoglobin. Subjects not satisfied with their body shape were having significantly lower amount of energy intake(p<0.05) than the subjects satisfied with their body shape. College women having mothers who graduated from university had a significantly decreased amount of energy, carbohydrates, fat and vitamin C(p<0.05). The mean RBC and serum iron of the subjects who were on a diet more than one month were lower than those of the subjects who were not on a diet(p<0.05).

This study was performed to investigate the effect of dietary intakes and nutritional status for fatty liver male patients with fatty livers. General characteristics, nutritional knowledge, and dietary intakes were obtained from fatty liver male patients aged 20-60yr living in Seoul and Kyunggi province by individual interview and blood samples. The Results were as follows : the mean age of the subjects was 39yrs. Old and over half the subjects were overweight. Although nutritional knowledge, recognition, and accuracy scores were good, these did not affect the subject's health. The average alcohol intake of subjects was 79.8g/day and the drinking duration was 5-40yrs(average : 17yrs). The subjects drank alcohol over 4tiles/week and preferred Soju. Most side dishes taken with alcohol drinking by the subjects were foods from animal sources. Half of the subjects also drank alcohol the next day for breakfast as a hangover-chaser. The reasons for drinking were due to social relationships and by habit. Vitamin D and folate were lower than the RDA for Koreans, and other nutrient amounts were higher than the RDA. The amounts of aspartate amino-transferase(AST), Alanine amino-transferase(ALT), ${\gamma}$-glutamyl transpeptidase(${\gamma}$-GTP), Triglyceride(TG) for the subjects were higher. In conclusion, fatty liver patients drank excessively and frequently. It seems that heavy alcohol drinking is more prone to overweight or obese people and contributes to fatty livers. Therefore, the subjects need to be taken effectively educated about alcohol-induced liver damage and the importance of a balanced diet for on healthy liver.

To promote health status, strategies and interventions to improve nutrition should be based on the proper diagnosis of the subject's eating patterns. The elderly usually have traditional food habits and preferences, and it is very difficult to change them. This study was designed to identify dietary behavior and food preference of the elderly, in order to provide baseline data for the Elderly Nutrition Intervention Program for the Public Health Center. A survey questionnaire was made for use by trained interviewers to query 151elderly people from 5 community elderly centers located in Suwon, Korea. The majority of them ate regularly and partook of all available side dishes. Their major dietary problems were frequent consumptions of salty foods, and eating too quickly. They consumed grains and vegetables regularly, but seldomly ate dairy products, fruits, meat and food prepared with oil. They also tended to eschew ready made processed food, high cholesterol food, and fast food. Also they did not dine out as much as younger people. Desirable eating habit score were not significantly influenced by socioeconomic variables and nutrition-related characteristics. These included nutrition knowledge, Nutritional Risk Index(NRI) and a score of health concerns. However, meal balance scores were significantly higher in the younger group(p<.05), the higher household income group(p<.05). According to stepwise multiple regression analysis, NRI was the most important determinant of a desirable eating habit score for the male elderly, whereas the score of health concerns was mo9st important for female elderly subjects. The greatest predictor of the meal f balance score was nutrition knowledge. The elderly liked sweet tasting food, grains, rice, stews and Korean style soups. They disliked sour food, dairy products, processed food, and bread. The results indicate that the Elderly Nutrition Education Program should focus on increasing consumption of dairy products, fruits and food with oil, prepared by traditional Korean cooking methods. It also suggests that the program planning should consider the socioeconomic status of the elderly, such as income and education level, as well as concern for health.

A deep understanding of the dietary patterns and nutrient intake is important for assessment of possilbe nutritional risk and for establishing nutrition improvement strategies. This study was conducted toexamine the dietary characteristics of a nutritionally poor elderly group compared to the middle-and highly-nourished group. Elderly participant was recruited from local elderly centers in Suwon city in 1998. Trained dietitians interviewed 119 elderly(35 males, 84 females) aged 60 years and over for collecting dietary data(24-hour recall) and related variables. Male and female subjects were grouped into high, middle, and low according to the mean nutrient adequancy ratio(MAR) tertiles. An analysisof the percentage of RDA(Recommended Daily Allowances of Korea) for each of the 10 nutrients showed that the male low-MAR group consumed below the RDA in all kinds of nutrients, and the female low-MAR group consumed nutrients below the RDA except vitamin C. An evaluation of nutrient density by Index of Nutritonal Quality(INQ) also showed a similar tendency. Thus, the INQ level of the male low-MAR group was significantly lower than the middle-or high-MAR group, especially in protein, vitamin A, thiamin, riboflavin, and phosphorus(p<0.05). Moreover, INQ level of female low-MAR group was significantly lower than that of the high group(p<0.05) in all nutrients. The female low-MAR group's daily food intake were also lower than those of the high-MARgroup in gains, fish, fruits, oil and beverages. The energy distribution from carbohydrates, fats and proteins showed that the male low-MAR group had significantly higher carbohydrate and lower fat proportions compared to each gender high-MAR group, respectively. The male and female low-MAR group had low scores about eating all side dishes. These findings indicate that a moderate increase of the meat/egg/fishes intake was needed by the male low-MAR group for improving nutrition adequacy, and an overall increase of the food quantity and quality was desired for the female low-MAR group. These data could be used for planning a community elderly nutrition program and establishing strategies for tailored guidelines for the individuals.

BACKGROUND/OBJECTIVES: Calcium is important but deficient in diets of young adult women. This study aimed to examine if cognitive factors and eating behaviors differ according to calcium intake based on the Social Cognitive Theory. SUBJECTS/METHODS: Subjects were female college students in Seoul, Korea. Three hundred students completed the questionnaire regarding calcium intake, nutrition knowledge, outcome expectations, self-efficacy and eating behaviors. Data on 240 students were analyzed using t-test or ${\chi}^2$-test. Subjects were categorized into two groups, high calcium intake (HC, ${\geq}650mg/day$) and low calcium intake (LC, < 650 mg/day), according to recommended intakes of calcium for women aged 19-29 years. RESULTS: The LC group constituted 77.9% of total subjects. Nutrition knowledge was not different according to calcium intake. Three out of 12 outcome expectations items were significantly different between the HC and LC groups. Subjects in the HC group agreed more strongly with the practical benefits of consuming calcium-rich foods, including 'taste' (P < 0.01) and 'going well with other snacks' (P < 0.05), compared to those in the LC group. Negative expectations of 'indigestion' were stronger in the LC group than HC group (P < 0.001). Among self-efficacy items, perceived ability of 'eating dairy foods for snacks' (P < 0.001), 'eating dairy foods every day' (P < 0.01), and 'eating calcium-rich side dishes at meals' (P < 0.05) differed significantly between the HC and LC groups. Eating behaviors including more frequent consumption of dairy foods, fruits or fruit juice (P < 0.001), anchovy, seaweeds, green vegetables, protein-rich foods (P < 0.05), and less frequent consumption of sweets or soft drinks (P < 0.01) were significantly related to calcium intake. CONCLUSIONS: This study found that outcome expectations, self-efficacy in consuming calcium-rich foods, and eating behaviors are important in explaining calcium intake. Nutrition education needs to address practical benefits, reduce negative expectations of calcium-rich foods, increase self-efficacy, and modify eating behaviors contributing to calcium intake.

The aim of this study was to determine whether Nutrition Quotient (NQ) for children, which has been developed from data on urban children, can be applied to children in rural areas. A total of 200 children (108 boys and 92 girls) in fifth and sixth grade at three elementary schools in rural areas of Gyeongbuk participated in the survey conducted during June 2012. Questionnaires consisted of items on food intake frequency and dietary behavior. Food intake data were obtained using the 24-hour recall method, and nutrient intake was calculated using the CAN-Pro 4.0 Program. Percentages of children who took less than the estimated average requirement were 76.5%, 49.5%, 45.5%, 33.5%, and 26.0% for calcium, vitamin C, iron, vitamin A, and folate, respectively. Significant associations were observed between intake frequencies of vegetables, kimchi, and fruits, and intake of vitamin C, folate, and dietary fiber. White milk and legumes showed positive correlation with intake of calcium and vitamin A. Eating breakfast, meal regularity, and diverse side dishes showed positive correlation with intake of folate and calcium. The 19 food checklist items could be categorized according to five factors. The mean NQ score of the subjects was 62.0, which was similar to that of urban children, 64.4. NQ score and factor scores for balance, regularity, and practice were significantly lower in children with lower socioeconomic level as compared to those with higher socioeconomic level. Higher NQ score showed an association with increased intake of vitamin B2, folate, vitamin C, and calcium. In conclusion, NQ offers a valuable instrument for evaluation of food habit and dietary quality of rural children as well as urban children, and children with low socioeconomic status should be monitored by testing with NQ checklist before implementation of nutrition programs.

BACKGROUND/OBJECTIVES: Despite the widespread use of dietary assessment tools, the validity of food records has not been evaluated in Koreans. We assessed the accuracy of estimated food records and the effect of a short education session in young Korean women. SUBJECTS/METHODS: Thirty women (aged 18-23 yrs) each completed 3 food records during a controlled-feeding study. One educational session was provided on day 2 of the study. Food records were analyzed for the accuracy of food items and portion size estimation according to food group (grains; meat, fish, eggs, and beans; vegetables; fruit; dairy; and oils and sugars) and type of dish (rice, kimchi, soup, side dishes, spreads, beverages, and snacks). Reported food items were categorized as exact, close, or far matches, exclusions, or intrusions. Portion sizes were evaluated as accurate, similar, or inaccurate estimates, or missing. The means of days 2 and 3 were used to assess post-education results. Paired t-tests were performed to assess the effects of the education session. RESULTS: The mean percentages of exact matches, close matches, far matches, and exclusions on day 1 were 80.9%, 10.9%, 2.0%, and 6.2%, respectively, and mean intrusions observed were 0.1. The education session slightly increased the accuracy of recorded food items. The percentages of accurate, similar, and inaccurate estimates, and missing portion sizes were 11.7%, 19.8%, 12.2%, and 56.3%, respectively, at baseline. The percentage of missing portion size estimates decreased to 14.0% after the education session, resulting in an increase in the percentages of all other estimates. An increase was observed in the accuracy of reported portion sizes of vegetables, rice, and kimchi. CONCLUSIONS: In young Korean women, estimated food records are highly accurate for food items but not for portion size estimates without prior education. A short education session can improve the accuracy of portion size estimation.

In this study, the contents of water-soluble vitamins $B_1$ (thiamin), $B_2$ (riboflavin), $B_3$ (niacin), and $B_{12}$ (cyanocobalamin) in namuls (wild greens), such as salads and side dishes, consumed in Korea were quantified by high-performance liquid chromatography (HPLC) with UV and fluorescence detection. All samples were prepared with recipes used in Korea. All analyses were performed under the quality control of vitamin $B_1$, $B_2$, $B_3$, and $B_{12}$. The vitamin $B_1$, $B_2$, and $B_3$ contents in namuls consumed in Korea were analyzed. The highest content of vitamin $B_1$ was $3.018{\pm}0.016mg/100g$ in Putgochudoenjang-muchim. The highest contents of vitamin $B_2$, $B_3$, and $B_{12}$ were $0.279{\pm}0.003mg/100g$ in Gul-muchim, $12.241{\pm}0.040mg/100g$ in Chamchi-salad, and $8.133{\pm}0.371{\mu}g/100g$ in Pijogae-muchim, respectively. These results showed that animal-based ingredients in salads provided for good intake of vitamin $B_{12}$. These results can be used as basic data for food composition tables and improvement of the national health of Koreans.

The purpose of this paper is to suggest an export strategy of seaweed products from Korea to Vietnam by analyzing the seaweed products consumption in Vietnam. This research surveyed 217 people in Hanoi and Ho chi minh, Vietnam. The result of the research revealed that consumers in Vietnam perceived seasoned kim as a healthy and easy-to-eat Korean food with snacks and side dishes, and it was recognized as a nutritious snack especially suitable for children to 20s. Kimbap is recognized as simple and healthy Korean food that is consumed as a substitute for meals at home, on the streets, and at restaurants. Sea mustard was the healthiest among seaweeds and are consumed in the form of sea mustard soup as good food for women, children, and the elderly. Summarizing the Vietnam seaweed market, it is a market that is similar to Korean seaweed consumer culture. In conclusion, we suggested a seaweed promotion strategy targeting women in their teens to twenties, communication on seaweed production process, experiential marketing strategy and seaweed food culture strategy.
