The assessment of sodium intake is complex because of the variety and nature of dietary sodium. This study intended to develop a dish frequency questionnaire (DFQ) for estimating the habitual sodium intake and a short DFQ for screening subjects with high or low sodium intake. For DFQ112, one hundred and twelve dish items were selected based on the information of sodium content of the one serving size and consumption frequency. Frequency of consumption was determined through nine categories ranging from more than 3 times a day to almost never to indicate how often the specified amount of each food item was consumed during the past 6 months. One hundred seventy one adults (male: 78, female: 93) who visited hypertension or health examination clinic participated in the validation study. DFQ55 was developed from DFQ112 by omitting the food items not frequently consumed, selecting the dish items that showed higher sodium content per one portion size and higher consumption frequency. To develop a short DFQs for classifying subjects with low or high sodium intakes, the weighed score according to the sodium content of one protion size was given to each dish item of DFQ25 or DFQ14 and multiplied with the consumption frequency score. A sum index of all the dish items was formed and called sodium index (Na index). For validation study the DFQ112, 2-day diet record and one 24-hour urine collection were analyzed to estimate sodium intakes. The sodium intakes estimated with DFQ112 and 24-h urine analysis showed $65\%$ agreement to be classified into the same quartile and showed significant correlation (r=0.563 p<0.05). However, the actual amount of sodium intake estimated with DFQ112 (male: 6221.9mg, female: 6127.6mg) showed substantial difference with that of 24-h urine analysis (male: 4556.9mg, female: 5107.4mg). The sodium intake estimated with DFQ55 (male: 4848.5mg, female: 4884.3mg) showed small difference from that estimated with 24-h urine analysis, higher proportion to be classfied into the same quartile and higher correlation with the sodium intakes estimated with 24-h urine analysis and systolic blood pressure. It seems DFQ55 can be used as a tool for quantitative estimation of sodium intake. Na index25 or Na index14 showed $39\~50\%$ agreement to be classified into the same quartile, substantial correlations with the sodium intake estimated with DFQ55 and significant correlations with the sodium intake estimated with 24-h urine analysis. When point 119 for Na index25 was used as a criterion of low sodium intake, sensitivity, specificity and positive predictive value was $62.5\%,\;81.8\%\;and\;53.2\%$, respectively. When point 102 for Na index14 was used as a criterion of high sodium intake, sensitivity, specificity and positive predictive value were $73.8\%,\;84.0\%,\;62.0\%$, respectively. It seems the short DFQs using Na index 14 or Na index25 are simple, easy and proper instruments to classify the low or high sodium intake group.

This study was conducted to develop a computerized food frequency questionnaire (FFQ) for assessing nutritional status of women of child-bearing age. Computerized food frequency questionnaire (FFQ) that reflect intakes of energy, carbohydrate, fat and protein was developed for women of child-bearing age. This FFQ is composed of 61 foods or food groups containing 192 dish items. To estimate of energy intake easily, we have developed a computer program that can be viewed on a computer screen in an actual size of dish items. Nutrient intakes of the last three months by the FFQ was validated with comparing the result of a 3-day diet record through 92 college students aged from 20 to 30. The level of energy, carbohydrate and sodium of estimating by the FFQ method was significantly higher than the level of a 3-day diet records method (p < 0.01). Pearson's correlation coefficients between the two methods were 0.50 for carbohydrate (p < 0.01), 0.55 for energy (p < 0.01) and 0.56 for protein (p < 0.01). Spearman's correlation coefficients were 0.53 for carbohydrate (p < 0.01), 0.55 for energy (p < 0.01) and 0.52 for protein (p < 0.01). The percent of subject in the lowest quartile in a 3-day diet record belonged to the first and second lowest quartile in food frequency questionnaire is 78.2% in energy, 91.3% in carbohydrate, 78.2% in protein, 69.5% in fat. Also, the percent of subject in the highest quartile in a 3-day diet record belong to the first and second highest quartile in food frequency questionnaire is 78.3% in energy, 73.9% in carbohydrate, 82.6% in protein, and 73.9% in fat. On the whole, the result of this study seemed to be in good agreement with other studies. Therefore, the FFQ developed by this study is considered to be a reliable tool to assess nutrients and food intakes for women of child-bearing age.

This study examined 389 customers visiting restaurants located in the Guemo mountain resort who filled out self-administered questionnaires. The results showed that 60% of the participants dined out monthly. The 30 to 40-year-old age group did so the most frequently, dining out one to two times weekly. For men, the favorite menu item was the sanchejeongsik along side traditional liquor and for women was the samgaetang. By age, the 20, 30, and 60-year-olds selected samgaetang as their favorite, the 40-year-olds selected traditional liquor, and the 50-year-olds selected the sanchejungsik. The reasons for selecting the dishes were because participants previously enjoyed them or considered the dishes healthy, regardless of sex or age. Participants suggested that the sanchejeongsik and samgaetang be promoted for tourism, without significant differences between gender. The current findings suggest that the quality of certain local menu such as sanchejungsik and samgaetang could be improved to become more nutritious for future customers. Also, traditional Korean liquor may become even more popular with visitors to the Guemo mountain resort if paired with simple menu items such as jeon or muk.

Since its introduction in"Jeungbosallimgyeongje" in the mid-1700s, Chogyetang has continuously changed as a cooked food while still reflecting the era as in the following four phases. In the first phase from 1766 to 1920, Chogyetang was served as a hot pot dish consisting of boiled chicken with spring onions, vinegar, soy sauce, oil, and egg. The second phase from 1930 to 1950 involved the removal of vinegar, an important seasoning. Instead, a wider variety of materials such as beef, sea cucumber, abalone, cucumber, and mushroom were added. Third, from the late-1950s to 1980s, there were significant changes both in the materials and recipe. Chogyetang was changed into a cold food for consumption in the summer in which sesame, a new material, was added to make soup. The prepared soup was then poured over the chicken and vegetables. Fourth, from the late-1980s to the present, sesame, the main ingredient added in the third phase, was removed. Instead, vinegar, mustard, and sugar were added in order to increase taste. Therefore, Chogyetang has been changed into an a la carte menu item in which vegetables and noodles are added to boiled chicken, and it has become a popular summer food consumed when eating-out.

The Development of a new menu item in a restaurant usually begins when your chef prepares a creative "brainchild" that he serves to you, the owner. If you are satisfied with the new dish, It gets a "go-ahead" signal, under the assumption that what appeals to you will appeal to a significant number of your customers. While many excellent and successful items have been created this way, It is not reasonable to expect that your tastes can represent the wide variety of your potential guests tastes. The purpose of this study is to examine the factors that have an influence on customers′ menu evaluation. A menu is a marketing tool which delivers restaurant′s image and message to customers needs and wants to restaurant. So far, studies on menu have been done in an analytical way from a management′s viewpoint and inadequate to reflect customers′ needs and wants. In this study is to examine the factors that have an influence on customers′ menu evaluation. The factors affected the customers′ menu evaluation of hotel restaurant in the three factors. Three factors are food service factor, menu copy factor, value of food. Correlation between the evaluation of criteria and selection of menu was examined.

This study was carried out to create a momentum for interest and understanding of local foods and provide base line data for the presentation of future effective development direction by investigating and researching cognitive characteristics, intake frequency, and preference about local foods targeting Pohang citizens. As a result of the investigation on intake frequency and preference of Pohang's local foods, in almost every item such as "gwamegi", "mul-hoe", "Guryongpo daege", "sashimi noodles", "mori noodles", "pidegi cuttle fish", "mulgomtang", "homchibap sikhae", "jesabap sikhae", "whale meat", "gaebokchi", "duchichijjim", "octopus sashimi", "roundnose flounder sashimi", "round flounder jorim", "fried round flounder", "gunsu sorasanjeok", "raw mustard muchim", "miyeongui dish", "sigeumjang", "chives dish", "rolled chives egg", "gokgang spinach", "pine dish", "yellow bean leaves muchim", "pickled green bean leaves", "green bean leaves watery kimchi", "Pohang sunrise bread", "black stone eel dish", "chili jjim", "red-pepper leaves namul muchim", "wild greens bibinbap", "acorn jello muchim", "oimiyeok changuk", "dongdongju", etc., significant differences were shown at the significance level of p<0.05~p<0.001. About understandings, views, development prospects, and development value and so forthof Pohang's local foods, more than 80% of respondents were positive, and in the questions asking concerns about local foods, more than half of the respondents gave a positive opinion, citing that they "have a little interest", and "tend to have an interest". Therefore, it can be seen that the future of local foods is bright. In the future, it is required that various cultural events related to local foods are held, a number of promotions are carried out, specialization of stores is distributed, and, at the same time, local foods are developed and generalized to suit modern sense, maintaining traditional taste in order to become global foods, as well as thedeformation of recipes.

This study was based on the information provided by 1,180 elementary school children (630 boys and 550 girls) of 5th or 6th grade in Changwon and Gimhae of Gyeongnam province. They were asked about perception and preference for rice foods by questionnaires. The purpose of this survey was to find the way of encouraging rice intake and preference which is currently getting lower because of increasing simple westernized eating habits, and to provide basic information needed for inheriting and improving our traditional rice-based dietary culture. The results are summarized as follows. Most of subjects (91.2%) thought that steamed rice is better than bread for own health. The reason why they chose to eat steamed rice was 'because it is good for health' (61.2%), and 'because it is staple food item that we eat everyday' (26.4%). Seventy one percent of girls and 52.7% of boys gave the answer 'because it is good for health' as the reason for eating steamed rice. The reasons for the importance of the rice-based dietary culture were 'because of its superior nutritional value' (40.8%), and 'because it is our traditional eating culture' (28.6%). While significantly more girls (42.9%) answered as 'because of its superior nutritional value', more boys (39.0%) answered as 'because it is our traditional dietary culture'. More boys (59.0%) preferred noodles than girls' (54.7%), and fruits were preferred more by girls than boys as substitution foods for steamed rice showing significant difference (p<0.01). They wanted rice product developed in the forms such as Ssalamyun (29.8%), Ssalmandoo (24.1%), rice noodles (20.6%), and rice bread (15.6%). The preference score on rice products of subjects was one dish meals (4.27) and drinks (4.26), snacks (3.72), convenience foods (3.61), and steamed rice (3.44) in order. Preferred food showing points over 4 were Ssalbap (plain steamed rice) (4.29) in steamed rice type food, Kimchi bokeumbap (4.56), Bokeumbap (4.55), Bibimbop (4.45), Omelet rice (4.44), Kimbap (4.42), Ddukkuk (4.33), Curried rice (4.33), Jajangbap (4.28), and Ddukmandookuk (4.24) in one dish meal type food, Samgak Kimbap (4.26) in convenience type food, Songpyun (4.48), Injulmi (4.18), Teokbokki (4.71), Ddukkochiguyi (4.46), and rice cookies (4.24) in snack type food, and Shikhye (4.61) and Misugaru (4.28) in drink type food. Based on these results, it may be said that elementary school children think the rice-based diet is good for health and this dietary culture should be inherited and developed not only in a traditional aspect but also in a nutritional aspect. Therefore, more studies are needed to develop various forms of rice food products and cooking recipes.
