School lunches serve to improve nutritional status and to promote the health of children. The purpose of this study was to investigate the portion sizes of school lunches served and consumed in Japanese elementary schools. In addition, gender difference in servings and consumption were also studied. A cross-sectional study was undertaken between October 2007 and February 2008 in schools located in Tokyo and Okayama, Japan. A total of 192 fifth-grade children attending four elementary schools participated in this study. Weighed plate waste methods and observation were used to collect dietary data for two non-consecutive days. The proportion of children who chose staple foods along with main dishes and/or side dishes for at least one day was higher in boys than in girls (respectively, for staple food: 42.1% vs. 9.3%, for main dish and/or side dish: 68.4% vs. 44.3%, P < 0.001). The ratio of initial amount served to amount offered was $0.88{\pm}0.11$ for boys and $0.84{\pm}0.10$ for girls (P < 0.05). The ratio of amount consumed to amount offered was $1.04{\pm}0.19$ for boys and $0.88{\pm}0.12$ for girls (P < 0.001). Weight was related to amount consumed both in boys (r = 0.222, P < 0.05) and in girls (r = 0.201, P < 0.05). These findings suggest that the nutritional standards of school lunch programs should take into account gender differences. Clearly, boys were more likely to consume more than the initial amounts served due to their higher propensity to take second helpings. Boys feel few reservations about taking second helpings to adjust their total intake. However, school lunch plans should take into consideration girls' reluctance to do so, by serving appropriate initial portion sizes.

The purpose of this study was to investigate the mutual relationship between food preference and nutrient intake status of high school students, based on the their personal characters which are sex, age, family type, number of family, mother's age, occupation, and school career. 439 students were selected with random stratified cluster sampling method. The study used a self-administrated questionnaire and 24-hour recall method for 5 days as instrument tools. Statistical methods applied to analyze the data were frequency, percent, Willcoxon Rank-sum test, Kruskal-Wallis test, ${x^2}-test$ by contingence table, and Spearman's correlation coefficient in non parametric statistical methods. Some of interesting results are as follows : 1. The correlation between sex and the set of characters of mother's age, school career and income is highly significant. However there is no any significant difference on the kinds of job and the types of family. 2. The relation between the preference of main dishes and the nutrient intake show a significant difference except to the noodles. This marks that preference of main dishes shows a direct proportion with the nutrient intakes except for the fat, vitamin A, vitamin C. 3. The preference of animal food marks a direct proportion with the nutrients such as energy, protein, fat, fiber, phosphorus, iron, vitamin $B_{1}$, vitamin $B_{2}$, and niacin 4. The preference of vegetable food gives some influence on the nutrient intake but the preference of soup is insignificant, the preference of Kimchi is in reverse proportion, and the preference of vegetable marks a direct proportion with the nutrient intake. 5. The preference of snacks marks a direct proportion with all kinds of nutrients intake except for the vitamin A, and vitamin C.

In this study, we analyzed 2-day food records of the 1990 Korean National Nutrition Survey data for 2,000 households, and investigated most popular menu patterns by area, income, meal. The basic menu patterns of Korean, excluding side dishes, were Rice+Soup, Rice+Stew, Rice, Others, Rice+Soup+Stew in the order of proportion for all analyzed sectors. And the proportion of menus with the rice as a main dish was about 90% on the whole. The most popular menus of Korean were Rice+Soup+Kimchi(4.52%), Noodle+Kimchi(4.30%). When they ate rice as a main dish, they had soup, kimchi, and 1 or 2 other side dishes. At large cities, Noodle+Kimchi was the most frequent menu(5.20%). On the other hands, small cities and rural areas, Rice+Soup+Kimchi+Cooked vegetable was common. For the households which salaries less than 5 million won, Rice+Stew+Kimchi is the most prevalent, but households which salaries higher than 5 million won, Noodle+Kimchi was most frequent. At breakfast and dinner, the proportion of Rice+Stew+Kimchi+Cooked vegetable was 4.70%. But at lunch, Noodle+Kimchi was the most frequent and other menu combinations based on noodle were also common. Therefore most households showed conventional rice based menu patterns, but these patterns were decreasing for the large cities, and high income households. Especially at lunch, they used various menus which were not based on rice.

Until recently, Japanese cuisine was known only for sushi and was still considered exotic outside the archipelago. However, today the number of specialized restaurants which serve other traditional foods is constantly increasing all over the world, making Japanese gastronomy one of the most influential. Japanese government has supported the promotion of national cuisine worldwide in different ways, making washoku (Japanese traditional cuisine) one of the main elements of Japan's soft power and cultural diplomacy. In this paper, I will analyse the connection between Japan's gastrodiplomacy, defined as the use of typical food and dishes as an instrument of soft power, and Japan's food security strategy. I will argue that the strategy of promotion of washoku worldwide is not a mere act of popularization of Japanese food but it is strictly related to the issue of the low self-sufficiency rate of the country, as the main objective of the government is the raise of food export, in order to foster agricultural production and improve self-sufficiency.

The purpose of this study was to define a portion size for dishes frequently consumed by Korean adults especially focusing on main dishes like rice, noodles, soups, and stews. From the original 8,019 people who took part in the Korea National Health and Nutrition Examination Survey (KNHANES) 2010, we analyzed the data for 4,556 persons aged 19 to 64 years and selected dish items consumed based on an intake frequency of 30 or more by all participants. The portion size of each dish item was set on the basis of the median amount ($50^{th}$ percentile) in a single intake by a single person. In the rice category, 15 items were selected, of which the most frequently consumed item was steamed rice with a portion size of 250ml. Among noodles and dumplings, the most frequently consumed dish was ramyeon with a portion size of 500ml. As for soups, the portion size was $250m{\ell}$ for kongnamul guk and $300m{\ell}$ for miyeoguk. In stews, the most frequently consumed items were kimchi jjigae followed by doenjang jjigae with a portion size of $200m{\ell}$ and $125m{\ell}$, respectively. In a comparison of portion sizes between the KNHANES 2010 and KNHANES 2005, the portion size of some noodles, soups, and stews tended to decrease from 2005 to 2010. Portion sizes established in this study for dish items consumed regularly by adults may be conveniently and effectively used in dietary planning, in nutritional education programs, and in assessing the dietary intake status of Korean adults.

'The Joobang' is a cooking book written purely in Korean which came from a Mr. Lee. It is unknown when and by whom this book was written, but it is inferred from red pepper mentioned in this book and from Korean-writting type that the book was written around in the mid-nineteenth century. The contents of 'the Joobang' consist of thirty seven items in all : sixteen items of rice alcoholics, five side dishes, eleven Tucks(rice cakes) and Guaja(cookies) and five processed materials. Cereals for making rice alcoholics were regular rice and sticky rice. In the first brew, rice alcoholics is made all from regular rice, and in the second brew, fifty six percent of regular rice and forty four percent of sticky rice was made use of. For five items of alcoholics forming 31.3% of alcoholics, flour was added, in which case the proportion of leaven to cereals was lower. There were four types of processing cereals in brewing rice alcoholics Jee-ae-bop(steamed rice, 60.9%), thick gruel with cereals ground and completely cooked(8.7%), thick gruel with cereals ground and half cooked (26.1%) and GooMung Tuck(doughnut-shaped rice cake, 4.3%). The comparison of the materials for brewing rice alcoholics and of the types of processing cereals presented in the seven cooking books purely in Korean(Umsik Deemeebang, JoobangMoon, Umsikbo, Sool-mandununbop, Kyuhap chongseo. The Kims' Joobangmoon and The Lee's Umsikbup) showed us the following facts ; Yihwajoo (rice alcoholics brewed around the blooming time of pear trees) and Kwahajoo(rice alcoholics which passed the summed time) were most often introduced and commonest, and the materials for brewing and the types of processing little changed over times. The materials for side dishes were all animal food, and vegetable food was little used for side dishes. Red pepper was used for seasoning. It is a problem of Korean traditional cooking that there were no units of measuring for side dishes. The main materials for Tuck(rice cakes) and Guaja(cookies) were sticky rice, regular rice and honey. There was a variety of terms for the process, from which we can see that the procedures of making Tuck(rice cakes) and Guaja(cookies) were very complicate. Processed materials were chiefly made of sticky rice and the material of firewood(oak trees) and the strength of fire(fire burning vigorously and fire turning to ashes) were described.

Objectives: Recommended Menu (RM) prepared according to the Target Pattern expected to meet the dietary reference intake (DRI) of nutrients. Nutritional adequacy of RM in 'DRI for Koreans 2015' were analyzed to verify whether such expectation was fulfilled. Methods: Dishes in RM are categorized by 5 food groups, and number and types of dishes for main meal and between-meals were analyzed. The energy and 12 nutrients (protein, dietary fiber, Ca, P, Fe, Na, K, vitamin A, thiamin, riboflavin, niacin and vitamin C) contents in 10 RMs were calculated using the food composition table (CD) in 'DRI for Koreans'. Energy, energy contribution ratio, and nutrient contents in 10 RMs for 18 age groups were evaluated based on the 'DRI for Koreans 2015'. Results: Number of dishes per meal were 4.83, and representative table setting consisted of cooked rice + soup (or stew) +3 side dishes. Energy contents of RM were 75~109% of estimated energy requirement (EER). None of the RM met the DRI of all 12 nutrients examined. Calcium was the most insufficient nutrient. Only 1-2 years' RM met the DRI, all the other RMs did not meet the calcium DRI. Dietary fiber and potassium contents were also insufficient in most RM. In adult male's RM, only 1 nutrient, i.e. calcium did not meet the DRI, but in female adult's RM, 5~6 nutrients did not meet the DRI. Energy contribution ratio of carbohydrate, protein, and fat in RM were 59.0~70.4%, 15.7~17.5%, 12.1~23.5%, respectively. And 4 RMs out of 10 exceeded the upper limit of acceptable macro-nutrient distribution range (AMDR) of carbohydrate and 3 RMs out of 10 RM were below the lower limit of fat AMDR. Contribution ratio of nutrients were ${\geq}40%$ by food groups were as follows: grain group in energy and carbohydrate; meat fish egg legume group in fat, protein, and niacin; vegetables group in dietary fiber, vitamin A, and vitamin C; milk dairy products group in calcium. Conclusions: RM prepared according to the Target Pattern did not meet nutritional adequacy as expected. Especially calcium, potassium, and dietary fiber contents are needed to be increased in many RMs. Further, energy content in RM needs to be adjusted for fat sugar food group assigned in Target Pattern and condiment.

This study has been conducted to research the interests and tastes in Korean cuisine aiming at Germans who have lived in Korea for over 6 months, create new Korean menu items to their taste, and provide preliminary data for the globalization of Korean cuisine. Germans living in Korea tend to prefer Korean dishes as much as German dishes, and males have more opportunities to have different Korean dishes than females through social activities. Most of them answered that they barely cook Korean food and gave low marks for the globalization of Korean food and ease of cooking. The main reason given for not cooking Korean food themselves was that it is complicated to cook, which is a direct indication of the lack of knowledge of the recipes. Therefore, the importance of simplification and standardization of recipes for the globalization of Korean food was revealed. From the study on Korean food preferences based on the restaurant frequenting practices of Germans, the most popular Korean restaurants were those which were located in popular restaurant districts or within walking distance and those with an elegant or tranquil ambience. To promote the globalization of Korean food, development of diverse easy recipes or education about Korean dishes for foreigners would enhance their understanding and familiarity of Korean cuisine.

This study investigated the characteristics of main house food cultures in Gyeonggi-do using a case study on the head family. The subject of this study was selected through an advisory committee of experts; it incorporated intangible and tangible elements of the main family based on relevant data. Selected representative main house of Gyeonggi-do had 12 parts in total. The entire investigation was conducted in five parts; literature search, telephone survey, in-depth interviews, inheritance food research of the head family, and cuisine demonstrations. Twelve families within the researched family clan had members of high merit or scholarly reputation qualified enough to serve bulcheonwi, a form of important religious worship. Food in Gyeonggi-do, specifically, can be served for Bongjesa jeopbingaek, which is a combination of performance of ancestral rites and greeting guests. Meat ingredients were frequently used. Articles of clothing were colorful and vivid, with wootgi that needed lots of work. Soup and steamed dishes tended to favor simple but fresh tastes that come with their cultural and historical context.
