This study was carried out to investigate preference and purchase factors of seaweed in some regional residents of Korea. Subjects were residents (n = 1,218) whose residential area was divided into inland and coastal region and the survey was done during December 2007. Especially, purchase factors of seaweeds was conducted only in married females (n = 353). The subjects are composed of 46.5% male and 53.5% female. Regional distribution of subjects was found to be 16~17%, with highest ratio in the age bracket of 20~29 years old. Proportion of students, at 29.8%, was the highest ranking occupation of the subjects. Preference score of seaweeds by region was highest for laver followed by brown seaweed and sea tangle. In terms of preference by gender, female subjects displayed higher preference score for green laver (p < 0.01), seaweed fusiforme, brown seaweed, sea tangle (p < 0.001) than the male subjects. Considerations being made when purchasing seaweeds for each region were in the order of freshness, taste and nutrition. In comparing the inland and coastal region, scores of freshness, convenience, design and color for the coastal region was higher, displaying significant difference.

2.A Study on Dietary Behavior of Children According to the Their Preferences for Fast Food.
Korean Journal of Community Nutrition 2004;9(2):204-213
The purpose of this study was to examine the dietary behavior of children according to their preference for fast food. The study was carried out on 470, 6th grade students (boys : 236, girls : 234) in September, 2002. The results are summarized as follows : The mean body mass index was 18.72 kg/m2 for boys and 17.76 kg/m2 for girls. The subjective health disorder symptoms for the group preferring fast food was not significantly different than that of the other groups. The group preferring fast food consumed an inadequate volume of food, and they had an irregular and unbalanced diet. Their intake of green vegetables, vegetables, protein foods, and seaweed was significantly lower than that of the other groups. The food habit score for the group preferring fast food was lower than that of the other groups, and they had irregular meal times and had unbalanced diets. The group preferring fast food had a preference for sweet tastes, whilst members of the other group preferred a savory taste. The first choice for fast food by the group preferring fast food was hamburgers, the reason being that it tasted good. Results show that children who have a preference for fast food need to correct their dietary behavior. As a result, proper nutritional education and intervention is required in order to improve the consuming habits of children and their preference for fast food.

Alginate, which is isolated from brown seaweed, is a bioabsorbable long chain polysaccharides, beta-D-mannuronic acid and alpha-L-guluronic acid. The authors produced alginates and alginate-colllagen as a disc form. Then, to evaluate the efficacy of alginate and alginate-collagen complex as a wound healing material, three full-thickness skin defects of 2 cm in diameter were made at the back of the New Zealand white rabbits. Three groups of dressing materials-alginate, alginate-collagen complex and vaseline gauze as control group - were applied on the wound and the results were evaluated grossly and histopathologically. The authors compared gross findings of sizes of healed wound, wound epithelization and wound contraction by tracing the remaining wound area at 5th, 10th, 15th, 20th, 25th day after wound introduction, and wound biopsy was performed at 3rd, 7th, 14th, 21st day, respectively. Alginate and alginate-collagen complex showed statistically higher percentage of wound contraction and wound healing compared to control group(p<0.05). Alginate-collagen complex showed statistically higher percentage of wound contraction, epithelization and wound healing compared to alginate alone. In conclusion, the result suggests that alginate has a good effect of wound healing and that alginate-collagen complex is more effective in wound healing than alginate alone.

OBJECTIVE: Articular cartilage has a highly limited capacity to repair because of lack of blood supply. There have been no effective modality to regenerate the articular cartilage and prevent degenerative changes. It is necessary to proliferate the cells in vitro, however the cells lose their phenotype during in vitro monolayer culture. Although it is not enough to increase the number of the cells in the three dimensional culture, it is a effective way to maintain their original phenotype expression. Alginate has been used as a good source of scaffold in chondrocyte three dimensional culture. The objective of this study was to find the most favorable scaffold for chondrocyte viability among various alginate extracted from natural source in chondrocyte three dimensional culture. METHODS: The alginate extracted from brown seaweed, Undaria pinnatifida and sea tangle, Laminaria japonica inhabitating near Korean sea and commercially available alginate were used. Chondrocytes isolated from adult pig were used. Three kinds of chondrocyte-alginate bead were made and incubated for forty-four days. Cellular viability and glycosaminoglycan (GAG) content were measured and compared. SPSS Version 10.0 was used for data analysis. RESULTS: Viability of chondrocyte and GAG content were increased as a function of time. Alginate from brown seaweed, U. pinnatifida appeared more favorable to maintain chondrocyte viability than others. The total GAG content was similar among three kinds of alginate CONCLUSION: Alginate extracted from natural see weed, especially brown seaweed, may be a good source to maintain chondrocyte viability in three dimensional culture.

5.Iodine Intake and Tolerable Upper Intake Level of Iodine for Koreans.
The Korean Journal of Nutrition 2011;44(1):82-91
The present study reviewed the effects of excess iodine intake on thyroid function and the incidence of thyroid disease and discussed the scientific basis for establishing a tolerable upper intake level (UL) of iodine for Koreans. ULs are defined as "the highest level of daily nutrient intake that is likely to pose no risk of adverse effects to almost all individuals in the general population." Koreans consume excess iodine from seaweed, and iodine intake is strongly influenced by seaweed consumption. However, no dose-response data derived from subjects consuming excess iodine frequently but not continuously during a lifetime are available. Therefore, the Korean DRI committee set the iodine UL to reduce the risk of adverse health effects by excess iodine intake for Koreans with distinctive seaweed-eating habits.

A valid food or dish frequency questionnaire needs to be developed in Korea for accurate dietary assessment because the dietary practices of Koreans are very different from those of other countries. This study was conducted to evaluate the accuracy of the newly developed, semi-quantitative, dish-based frequency questionnaire (Semi-DFQ) with 12-day dietary records (12-DRs) as a gold standard. The study subjects were 115 men and 173 women aged 30-65 years old. We calibrated the frequency, portion size and daily intake of 112 dish items reported in Semi-DFQ with those in 12-DRs by Spearman rank correlation coefficients (SCCs). The consumption frequency and portion size reported in Semi-DFQ were higher than those in 12-DRs. The SCCs for the consumption frequency of various dishes ranged from -0.07 (fried seaweed) to 0.70 (instant coffee), the portion size ranged from -0.09 (cold seaweed soup) to 0.68 (soju), and the daily intake ranged from -0.07 (fried seaweed) to 0.71 (soju). The SCCs were higher for dishes consumed daily, such as steamed rice, milk, coffee and alcohol, than those of foods eaten rarely. The overall agreements between the Semi-DFQ and 12-DRs were low for categories of consumption frequency and portion size, even though some dishes showed high SCCs. The SCCs of the two methods in consumption frequency and amount were higher among the women and younger subject. The results revealed the limitation of the Semi-DFQ for evaluating the status of usual individual intake. Therefore, the Semi-DFQ can be used in addition as dietary records and 24-hour recall depending on the research aims.

BACKGROUND AND OBJECTIVES: This study was to investigate the association between the previous history of seaweed intake after childbirth and subclinical hypothyroidism (SCH) occurrence in Korean women based on the latest nationally representative epidemiological survey data, the Sixth Korea National Health and Nutrition Examination Survey (KNHANES VI).MATERIALS AND METHODS: This study used data from KNHANES VI, a cross-sectional, nationally representative survey that comprises a health interview survey, health examination survey, and nutrition survey. Of the initial 22,948 Korean participants enrolled in KNHANES VI, 2,046 women were selected for this analysis. To examine SCH, the thyroid-stimulating hormone (TSH) reference range was defined using a population-based TSH range.RESULTS: Subclinical hypothyroidism was increased in those who consumed seaweed soup after childbirth, but this was not significant (OR 1.3, CI: 0.80–2.13, p=0.293). However, the odd ratio for SCH differed according to the duration of seaweed soup consumption. When seaweed soup was consumed within 1 week after birth, the OR was increased in the crude model (OR 2.61, CI: 1.39–4.89, p=0.002), but this was no longer significant in the adjusted model (OR 1.89, CI: 0.79–4.50).CONCLUSION: The notable finding from this study is that the previous history of excessive seaweed consumption during post-partum period may not be a risk factor for SCH in Korean women.

Journal of the Korean Dietetic Association 2002;8(3):289-300
The purpose of this study was to investigate the intake and preference of Kimchi in middle school students. A questionnaire was used as the instrument of investigation. The subjects were 375 male and 278 female students in Masan and Changwon City. The main results of this study are as follows. Fifty-nine point seven percent of the subjects liked Kimchi, whereas 3.7% of them disliked it, and the main reason liking Kimchi was 'hot taste' of Kimchi. Korean cabbage Kimchi and cubed radish Kimchi were highly preferred. And the preferred dishes made with Kimchi were stir-fried rice with Kimchi, Kimchi stew, pan-fried Kimch, seaweed rice with Kimch, Kimch pancake, Mandu with Kimchi, pork stew with Kimch. More than 90% of the subjects had eaten 6 kinds of Kimchi : Korean cabbage Kimchi, cubed radish Kimchi, radish leaves Kimchi, radish root & leaves Kimchi, watery radish Kimchi, white Kimchi. The frequency of Kimchi intake was 55.1% of the subjects ate Kimchi in every meal time, and 21.9% ate 2 times in a day. They preferred 'well fermented' and 'freshly prepared' Kimchi, and it was significantly difference between gender, male students more liked 'freshly prepared', whereas female students more liked 'well fermented' Kimchi(p<0.01).

10.Revision of the Target Pattern based on Single Serving Size of Dishes for Korean Adolescent Meal Plan.
Korean Journal of Community Nutrition 2015;20(1):21-29
OBJECTIVES: Maintaining a balanced diet is very crucial for adolescents. However, adolescents, who may have a short notion about the amount of food, find it difficult to plan daily meals by applying the target pattern proposed by the Korean Nutrition Society. This study was carried out to revise the target pattern based on cooked dishes instead of raw material food groups as an easier way for Korean adolescents to plan their meals. METHODS: Target pattern for Korean adolescents were revised based on the following: 1st, categorize dish groups, 2nd, calculate representative values of each dish based on the adolescent' intake amount. 3rd, assign the recommended number of intake for each dish. Validity of the target pattern for Korean adolescent meal plan was examined by the energy content, energy contribution ratio, and NAR & INQ of nutrients. RESULTS: The 11 dish groups categorized were bab; gook.tang.gigae; side dishes of meat, fish, egg, legume, kimchi, vegetable, seaweed; and between meal of fruit, and milk.dairy product. Based on the representative energy values, recommended number of intake were assigned to each dish. For boys, bab and gook.tang.gigae: 3 each; meat, fish, egg, and legume: 1 each; kimchi and vegetable: 3 each; seaweed: 1; fruit and milk.dairy product: 2 each were assigned. For girls, bab and gook.tang.gigae: 2 each; meat, fish, egg, and legume: choice of 3 dishes, 1 each; kimchi and vegetable: 3 each; seaweed: 1; fruit and milk.dairy product: 2 each were assigned. Energy contents, energy contribution ratio of carbohydrate, protein, and fat for boys and girls were in adequate range. The NARs were 1.0 and INQs were > or = 1.0 for all nutrients examined. CONCLUSIONS: Revised dish-based, instead of food-based adolescent target patterns for boys and girls were easier and a valid way of Korean adolescent meal planning.
