Objectives: The purpose of the study was to develop a textbook of the integrated education of Korean food culture and language for married female immigrants. Methods: An analysis was conducted with the textbooks and researches for married female immigrants, and dietary life related contents were extracted. The contents were organized by activity oriented approach which is acquired the culture. The evaluation was conducted through depth interview with 6 married female immigrants through an analysis of the qualitative materials. Results: The text book comprised of 30 Korean food recipes with the target expressions and vocabularies. It also included Korean basic table setting, Korean table manner, main dishes and side dishes, basic cutting, seasoning and garnish, measure of the ingredients, symbolic food, regional food culture, choice of food ingredients, shopping, bargaining, taste expression, color expression, all sorts of spices, Korean traditional festival food, and seasonal customs and food. For intensifying communication, activity which is close to real life was added. Through cooking, married female immigrants expose words and sentence patterns and that allows to evaluate their level of understanding. We observed that the developed textbook is suited for married female immigrants' needs and cognitive level. The text book included a comparative study between Korean culture and their country's culture, which could provide the motive for accepting each other's cultures. The study showed how to develop a textbook that integrates Korean language education and Korean food culture and how to apply the textbook in real life. Conclusions: The correct understanding about Korean food culture could lead to improvements communication ability. Useful information which relates to Korean food, recipes, and food culture could increase daily life satisfaction. Conducting both cultural education and language education could increase the participation of married female immigrants in learning activities. Therefore this study could help these females to adapt Korean society and manage family dietary life effectively.

In order to establish the basic scientific data on the fermentation characteristics of chonggak kimchi (CGK), we studied with CGKs prepared at different seasons and stored at various temperatures ($5{\sim}23^{\circ}C$). Changes in pH and acidity of CGK fermented at different temperatures were typical. However, acidity of summer CGK stored under $15^{\circ}C$ did not reach 1.0% since the amount of reducing sugar in the summer radish was lower by over 1% than the ones from the other seasons. Growths for Leuconostoc and Lactobacillus spp. over 8.0 logCFU/mL were observed in CGKs fermented above $10^{\circ}C$. Changes in Max G, cutting force, of CGK from different seasons were apparent. Max Gs for spring and summer CGK were decreased immediately right after storage while Max Gs for winter CGKs were increased slowly during storage. According to the results of sensory evaluation, CGKs revealed the highest overall acceptability when acidity of kimchi reached $0.7{\pm}0.1%$ under the given fermentation condition. However, CGK prepared with radish from winter or summer season tasted better than the one made in the spring. But the edible periods for winter CGKs were longer, compared with summer CGKs fermented at the same temperature. In conclusion, CGK fermented at $10^{\circ}C$ in the winter season gives a better taste with longer edible duration than the other CGKs.

This study is attempt to develop for Korean traditional food data integration system with food database. We are collected all kinds of traditional Korean foods, and referred to document and classified according to food types and cooking methods. Also we are classified 6 types of traditional Korean foods as follows: traditional common, royal, local, festival, rites, and Buddhist temple foods, And we integrate all of that databases for using a specialist or not. We researched for Korean traditional food by cooking type and planed organization for the standardized code and construction for database of Korean traditional foods. It was combined all of them, constructed for Korean traditional food data integration system. Korean traditional foods are classified with 10 provinces local foods, 18 festival foods by seasonal divisions reflecting traditional Korean holidays; and 9 classes rites foods. Korean traditional food using a traditional Korean food classification system was investigated a total of 7,289 kinds foods according to food types. those were 2,585 kinds traditional common foods, 142 kinds of royal foods, 2,137 kinds of local foods, 515 kinds of festival foods, 403 kinds of rites foods, and 1,507 kinds of Buddhist temple foods. And Korean traditional foods included 980 kinds of main dishes, 4,456 kinds of side dishes, 873 kinds of tteok lyou, 515 kinds of hangwa lyou and 465 kinds of emchong lyou. It is therefore recommended that knowledge of traditional Korean foods be preserving and develop their excellence and to further studies.

The purpose of this survey was to investigate the nutrient and food intake and food habits of the aged Jeju island. The survey was conducted to 102 persons, 50 persons aged 65 to 74 years and 52 persons aged 75 years over from July 5 to 25, 1981. The result obtained was summarized as follows; 1. Average nutrient intake per day Calorie intake was 1408 ㎉(which was 64% of RDA) for male and was 1343 ㎉ (84%) for female aged 65 to 74 years. For male aged 75 years over calorie intake was 1316㎉ (60%) and for female was 1292㎉ (81%). According to the intake of calorie, the ratio of carbohydrate, protein, fat, were average 74.8%, 15.1%, 10.1%. Protein intake was insufficient quantiatively, but the proportion of animal protein to total protein intake were 26.1 to 33.5%. Other nutrient intake, such as Ca, vitamin A and C were lower than the recommended dietary allowance. 2. Food intake In per capita food consumption were 69.1g to 744.7g and average 320.1g of cereal (125.1g of rice and 160.5g of barley) and 63.9g of fishes. Total food consumption and vegetables were diminished by older age. 3. Correlation assessment The correlation coefficient between residental stus lived with family, high activity, good health, and nutrient intake were significant (P<0.05). Poor teeth had influence on less nutrient intake, but was not significant. 4. Food preferences Food liked over 70% of subjects were persimmon, fishes, leef, tomato, and boiled rice with barley, etc. owing to tender food, economical reasons, seasonal influence, and food habits. Food disliked over 20% of subjects were instant noodle, small sardin, boiled rice, and ice-crea, etc. The majority of subjects had never had the processing food, such as ham, sausage, butter and margarine, etc.

This study was performed to develop the semi-quantitative food frequency questionnaire (SQFFQ) for assessing the usual dietary intake of Korean adolescents. For that, we used 24 hour recall data from the 2005 NHANES(the Third Korean National Health and Nutrition Examination Survey). The cumulative percent contribution and cumulative multiple regression coefficients of 17 nutrients(energy, protein, fat, carbohydrate, fiber, calcium, phosphorus, iron, sodium, potassium, vitamin A, retinol, ${\beta}$-carotene, thiamin, riboflavin, niacin, vitamin C) of each food were computed. Among 687 food items, 265 food items were selected and grouped depending on similarities in ingredients, nutrient profiles, and/or culinary usage and re-added food items which were excluded for seasonal effect. Finally, total 19 food groups, 87 food items, were included in SQFFQ. Food intake frequency was quantified using nine categories. The portion size was classified depending on the average size of each selected food item. Each portion size was then categorized as one of three amounts: small (0.5 times), medium (1 times), and large (1.5 times). The SQFFQ covered 91.9% of the intake of 17 nutrients in 2005 NHANES and 86.6% in 2001 NHANES. Therefore, by testing the validity of developed SQFFQ using nutrient intakes, this list was valid to evaluate the usual daily intake in Korean adolescents.

As part of study on the microbial food web in the southern Jeju Island of Korea, Planktonic tintinnids and aloricate oligotrichs were investigated from July 1998 to June 2000 to understand seasonal variation and water mass indication with environmental factors. 39 species of tintinnids were identified representing 1 order, 11 families, 20 genera. Tintinnid abundance ranged from 100 to 5,400 cells.1$^{-1}$ (mean 314 cells.1$^{-1}$ ), and oceanic species were mainly dominant in fall and winter season, while neritic species were a little pre- dominant in spring and summer season. 15 species of aloricate oligotrichs were identified representing 1 order, 5 families, 7 genera, and many belonged to genus Strombidium which was most abundant and most frequently occurred in many months. Abundance of aloricate oligotrichs ranged from 140 to 21,000 cells.1$^{-1}$ (mean 2,356 cells.1$^{-1}$ ). Species diversity and standing crops of tintinnids were quite different according to seasons, but few seasonal variations were detected in aloricate oligotrichs. In terms of water mass indication tintinnids represented obvious characteristics which were affected by marine environmental factors, but alor- icate oligotrichs had no such apparent indication as tintinnids. Ciliates were more abundant and more diverse in inshore than in offshore station. Total carbon biomass of ciliates ranged from 0.01 to 136.06 $\mu\textrm{g}$C.1$^{-1}$ (mean 5.01 $\mu\textrm{g}$C.1$^{-1}$ ). The carbon biomass, however, did not coincided with seasonal variations of abun- dance Vertical profiles of mean abundance of both tintinnids and aloricate oligotrichs were similar, and had same trend as those of mean chlorophyll o concentration. It suggests that phytoplankton and ciliates reflected the prey-predator relationship in the study area.

The purpose of this study was to investigate the seasonal variations in water, protein, lipid, ascorbic acid, and ${\beta}-carotene$ contents of 17 vegetables and 4 fruits that are available all the year round and frequently consumed by Koreans. The water contents of the fruits ranged from 83-89%, and the vegetables contained more water than the fruits. The apples and pears had more water in the spring and summer than in the fall and winter. The tangerines showed a high water content in the winter, whereas the strawberries contained more water in the fall. The vegetables also showed seasonal variations in water content. The protein contents of the fruits were lower than 1%; the cucumbers contained 0.1% protein, which was the lowest level, but spinach, lettuce, bean sprouts, sesame leaves, and mushrooms had more than 1% protein. The ascorbic acid and ${\beta}-carotene$ contents of the apples, pears, and tangerines were higher in the fall and winter than in the spring and summer. The vegetables, in general, contained more ascorbic acid than the fruits. The cabbage and radishes showed higher ascorbic acid contents in the fall and winter than in the spring and summer, indicating that vegetables as well as fruits are more nutritious during their harvest season. The zucchini, spinaches, and green peppers had higher ${\beta}-carotene$ contents in the winter than in the other seasons. The above results show that there were seasonal differences in the ascorbic acid and ${\beta}-carotene$ contents of the fruits and vegetables. In addition, the fruits and vegetables had a tendency to contain more ascorbic acid and ${\beta}-carotene$ in the season they were harvested. Therefore, we recommend the consumption of those fruits and vegetables during their harvest season.

The southern rough shrimp Trachysalambria curvirostris (Stimpson) was monthly sampled from the coastal area of Yeosu, Korea from June 2000 to May 2001 and its stomach contents were investigated. Mysids and amphipods were the most dominant prey, comprising >40% of the diet in both % occurrence and % abundance. In particular, mysids were most important food without regard to seasons, size classes, or sexes. The abundance and occurrence composition of food items showed a seasonal fluctuation: mysids and amphipods were the predominant prey items in spring (33.8%), summer (41.1%), autumn (43.9%), and winter (49.2%). For small-sized shrimps (＞25 mm CL), mysids and amphipods consist of more than 45% of its food in both % abundance and % occurrence. For large-sized shrimps (>25 mm CL), these were clearly dominant. The quantities and items of food did not differ in both genders, which mainly fed on mysids and amphipods. The trophic diversity and equality of diet varied with seasons and size classes. The diet diversity for smaller shrimps was highest in spring, while that for the larger shrimp lowest in winter. Also, the mandibular structure of Trachysalambria curvirostris indicates that the species is carnivorous.

Codonopsis lanceolata has long been used as a seasonal food and as a traditional tonic medicine with anti-inflammatory and anti-oxidation properties. The present study investigated the in vitro effect of Codonopsis lanceolata extracts on immune function in mice. After preparing a single cell suspension splenocyte proliferation was determined by the MTT(3-[4,5-dimethylthiazol-2-y]-2,5-diphenyl terazolium bromide) assay. The cytokines IL-1${\beta}$, IL-6, and TNF-$\alpha$ were not secreted by macrophages stimulated with or without LPS as determined by an ELISA cytokine kit assay. After a 48-hr incubation with the mitogens ConA or LPS there was an increase in splenocytes proliferation and in the production of IL-1${\beta}$, IL-6, and TNF-$\alpha$ in the suspensions supplemented with 50, 100, 250, 500 ${\mu}g/m{\ell}$ Codonopsis lanceolata water extract. The results suggest Codonopsis lanceolata water extract may enhance immune function by regulating splenocyte proliferation and stimulating cytokine production.
