This research was performed to investigate mother's influence on their children's dietary life. We surveyed 312 elementary school students and their mothers in kyungpook province, and analyzed the responses using SAS 8.0 statistical program. The results showed that mothers' consuming behavior of processed foods was closely related to their children's dietary life. In detail, mother's preference, eating frequency, positive recognition on processed foods negatively affect on their children's dietary habit and snacking behavior. Also, the children whose mother has higher preference on processed foods showed significantly higher preference on cereals(p<0.05), fast foods(p<0.001), and carbonated beverages(p<0.001). Interestingly, mother's influence was stronger on children's eating frequency than preference of processed foods. The children whose mother has higher preference and eating frequency of processed foods ate significantly less vegetables(p<0.001), milk products(p<0.05), and more cereals(p<0.001), noodles(p<0.001), confectionary(p<0.001), fast foods(p<0.01), carbonated beverages(p<0.01). These results show that mothers' consuming behavior of processed foods significantly influences on their children's dietary life, which suggests the importance of mother's reasonable consuming attitude and behavior on dietary life. To promote children's healthy dietary life, therefore, the education programs for parent and children should be developed and practically used at school.

In order to develop Houenia dulcis with natural food application the effect of Hovenia dulcis fruits powder content the physical, textural and sensory properties of noodles were examined. The analysis of the contents of free amino acids showed that 17 kinds of amino acids were detected and highest in 3$\%$ Hovenia dulcis fruits powder contents. The weight and the volume of cooked noodle were highest in control the more added of Houenia dulcis fruits powder contorts lessen the weight and the volume (p < 0.01, p < 0.001), the water absorption ratio was highest in control group. Hunter color value of noodle showed that L value was 7.62 in control, a and b values were highest in 5$\%$ added group. More added Houenia dulcis fruits powder contents increased a and b values (p < 0.001). Hardness, cohesiveness (p < 0.05), gumminess and brittleness (p < 0.001) were highest in control, springiness was highest in 1$\%$ added group (p < 0.001). Scanning electron micrographs of noodle showed that more added of Houenia dulcis fruits powder contents made the particle uniform, so softer and larger. Sensory properties showed that color of noodle and herb flavor were thicker in more added of Houenia duzcis fruits powder contents (p < 0.001). The taste was highest in 3$\%$ added Houenia dulcis fruits powder contents. Overall acceptability was also highest in 3% added group (p < 0.01).

We attempted to define the sources of sodium intake for the Korean population at prepared dish level to provide a basis for developing sustainable nutrition policies and feasible programs for sodium intake reduction. Dietary intake data from 2008 and 2009 Korea National Health and Nutrition Examination Survey was used in the analysis for sodium intake sources. Sodium intake from individual dish consumed by each subject was calculated and used in delineating major sodium sources at dish and dish group level for sub-populations of different sex and age. Also, sodium intake was compared between eaters and non-eaters of some specific dish groups with considerable contribution to total sodium intake. The number of subjects included in the analysis was 18,022 and mean sodium intake was 4,600 mg/capita/day. Major sources of sodium intake at dish group level were in the following order: kimchi (1125 mg, 24.5%), noodles (572 mg, 12.4%), soups (488 mg, 10.6%), stews (399 mg, 8.7%), and cooked rice (284 mg, 6.2%). The magnitude of contribution to total sodium intake by soups and stews was different by age group. Sodium intake difference between eaters and non-eaters was much larger for kimchi group (2,343 mg for male, 1,452 mg for female) than for soups or stews. Interaction between consumption of aforementioned specific dish groups and age was highly significant (p < 0.0005) for both sexes. This study revealed an importance of having not only the control over sodium content of foods/dishes, but also the customized approach for different groups of population to accomplish an appreciable reduction in sodium intake.

Objectives: This study was conducted to investigate the effect of low sodium diet education program on dietary habits, diet quality, and measures of obesity in overweight or obese middle-aged women. Methods: Subjects were 81 individuals aged 45 years or over, who completed an 8-week nutrition education. The subjects were divided into a normal group (N = 30) and an overweight-obese group (N = 51) according to the BMI. The effects were evaluated by anthropometric measurement, biochemical analysis, questionnaire, and diet records before and after the program. Results: Overweight-obese group showed significant decreases in weight (p < 0.0001), BMI (p < 0.0001), percent of body fat (p = 0.0087), waist circumference (p < 0.0001), systolic (p = 0.0003) and diastolic blood pressure (p = 0.0261). Nutrients intakes were not different between the two groups and only sodium intake was decreased after education. Total score of general dietary habits, dietary behavior related to sodium intake, dietary diversity score (DDS), diet variety score (DVS), and diet quality index-international (DQI-I) were improved in both groups compared to the baseline. Overweight-obese group showed significant improvement in 'having fruits everyday', 'having fish everyday', 'trying to eat many kinds of food', 'eating less broth when eating soup, stew, and noodles', 'eating less kimchi and salt-fermented vegetable', and 'propensity to think that dishes should be pretty seasoned'. In addition, moderation of empty calories food (p = 0.0064) and macronutrient ratio (p = 0.0004) were improved in the overweigh-obese group, but in the normal group, the results did not reach statistical significance. Conclusions: These results suggested that low sodium diet education program may contribute to obesity management by improving diet quality and dietary habits in middle-aged women.

This study is performed to examine the meal management attitudes of housewives who had elementary schoolchildren in the remote rural areas(RA: n = 318, $37.2{\pm}0.3$ years of age) in comparison to those in their vicinity urban area(UA: n = 349, $36.9{\pm}0.2$ years of age) in the Chungnam province in Korea. The subjects were asked to fill out the questionnaire on their attitudes of meal management for their families. The results obtained in this study were as followings: (1) Most husbands of the subjects had a farming job in the RA while they had salaried workers in the UA(p<0.001). Education levels of both subjects and their husbands were lower in the RA than in the UA. Nuclear families were dominated by both groups, however single parent-family and step parent-family were more prevalent in the RA than in the UA. (2) in terms of ways of getting foods such as grains, meats, eggs, vegetables and fruits, the RA housewives relied more often on self-production than did the UA housewives(p<0.001). (3) The frequency of purchasing unprocessed foods was lower in the RA than in the UA(p<0.001). The RA housewives purchased the convenient foods such as instant noodles(p<0.05), ready to eatsoups(p<0.001), retort pouch foods(p<0.05) and instant teas(p<0.05) more frequently than did the UA housewives, while tuna, canned in oil(p<0.01), milk and their products(p<0.001), soybean products(p<0.001) and snacks(p<0.01) were purchased less often by the RA housewives. (4) Family members except housewives engaged more often in meal preparation in the RA than did those in the UA(p<0.001), which was more strongly observed for dinner. The time spent in preparing the dinner was shorter in the RA than in the UA(p<0.001). (5) The degrees of endeavor to provide the subjects' offspring with balanced meal(p<0.001) and nutrition education(p<0.01) were lower in the RA than in the UA. The RA housewives had more difficulty for performing meal management because of 'over work-related fatigue', 'insufficient money to purchase foods' and 'far distance from grocery' than the UA housewives(p<0.001). The RA housewives had lower score on nutritional knowledge(p<0.001) and wanted more strongly nutritional knowledge to improve the quality of family's meal than did the UA housewives(p<0.01). Therefore, the RA housewives had various problems regarding meal management such as 'over work related to fatigue', 'food-purchasing inconvenience', 'low economic status of family' and 'lack of nutritional knowledge'. As a consequence the RA housewives relied on cheap convenient foods more often in order to prepare the meal easily than did the UA housewives. These findings emphasize the need in the RA for nutrition education for housewives and a range of nutrition policies that focus upon the social and economic determinants of food choice within families to improve the nutritional status of the RA residents.

In an attempt to make dried noodles with composite flours utilizing rice and wheat flours, noodle-making characteristics were improved by the addition of popped rice and wheat flours to rice flour. Their quality was studied in terms of physical properties, noodle-making characteristics, cooking quality test and sensory evaluation. Dried noodle of the composite flour was produced by the conventional method. The results are summerized as follows; 1. In comparing the composite flours, the rice flour containing 30% popped rice flour had a lower maximum viscosity than that with 40% popped rice flour by method of amylograph. The composite flour(20% rice+30% popped rice+50% wheat flour) with added 2% xanthan gum showed the viscosity characteristics which was similar to that of wheat flour. 2. Addition of $1.5{\sim}2.0%$ xanthan gum and $40{\sim}50%$ wheat flour to rice and popped rice flour mixture helped to improve the noodle making properties and the cooking quality, and the noodle making properties and the cooking quality of the mixed flour were almost the same as those of wheat flour alone. 3. The composite flour (rice+popped rice+wheat flour) with xanthan gum showed a higher score in sensory evaluation than that without xanthan gum. The general acceptability scores obtained with the noodle products made of the composite flours with 30% popped rice flour was not significantly different from that of noodle products made of wheat flour alone. However, the noodle products made of the composite flours showed rather higher scores in odor and palatability than the products made of wheat flour alone.

This study conducted a survey with 203 single households among men and women in their 20s to 40s who were living in metropolitan areas from October 6 to November 4, 2012 in order to investigate the dietary attitude of the single households. The ratio of single households who had three meals a day regularly was 2.85 points, which was lower than the normal level, and it turned out that those in their 20s and 30s had meals more regularly than those in their 40s did (p<0.001). As for the irregular meal time, most were breakfast (85.9%), and it turned out that they often skipped meals mostly because they did not have time to eat and (41.7%) or because that bothered them (26.0%). 62.6% of the single households did overeating and most of them (39.4%) did overeating because of their irregular meals. Of the single households, women or persons who had lived alone for less than 3 years or more than 7 years cooked at home, more often (p<0.05), and most of them (42%) cooked noodles, easy to cook, but women cooked Korean food-based homemade food such as rice (31.7%) or soup and stew (21.2%), often (p<0.05). It turned out that 36.9% of the single households often ate out about two to three times a day, and as for their favorite eating-out menus, 39.4% were Korean food, followed by Western food (23.8%), flour-based food (13.5%), fast food (9.8%), Chinese food (7.3%) and Japanese food (6.2%). Lastly, as for inconveniences when they ate out, most were the 'price' (22.8%), followed by 'too much amount of food for one person' (20.2%) and 'limitations in menu selection' (19.2%). As a result of this study, it appeared that the single households had an irregular dietary life, often did overeating and often ate out, so it is judged that it would be necessary to develop a variety of nutritionally-balanced HMR food and eating-out menus in a reasonable price range for their healthy dietary life.

The purpose of this study was to develop sodium reduced foods for 10 representative high sodium foods often served in the food service industry, and to conduct sensory evaluation on the foods. The foods are kimchi, cucumber salad, banquet noodle, seaweed soup, ahuk soup, pork kimchi stew, red pepper paste pork chops, beef bulgogi, grilled mackerel and saury stew selected based on data from the 2010 national health and nutrition examination survey. The sodium contents of chinese cabbage kimchi were 688.1 mg in the control, 587.3 mg in the 15% reduced sodium sample group (level 1), and 486.5 mg in the 30% reduced sodium sample group (level 2). The corresponding sodium contents of cucumber salad were 406.4 mg, 345.5 mg, and 284.6 mg. The sodium contents of banquet noodle were 1080.2 mg, 912.2 mg, and 765.8 mg, respectively. The sodium contents of seaweed soup were 459.4 mg, 392.1 mg, and 333.0 mg, respectively. The sodium contents of ahuk soup were 615.3 mg, 534.9 mg, and 434.4 mg respectively. The sodium contents of pork kimchi stew were 1156.2 mg, 988.3 mg, and 820.2 mg respectively. The sodium contents of grilled mackerel were 624.6 mg, 557.4 mg, and 456.9 mg respectively. The sodium contents of red pepper paste pork chops were 723.7 mg, 615.0 mg, and 505.3 mg, respectively. The sodium contents of beef bulgogi were 678.3 mg, 561.9 mg, and 473.3 mg, respectively. The sodium contents of saury stew were 676.0 mg, 574.6 mg, and 470.9 mg respectively. Sensory evaluation was conducted with a total of 30 samples consisting of 10 control food groups, 15%, and 30% reduced sodium food groups. Results showed sodium reduction up to level 1 or 2 in chinese cabbage kimchi, cucumber salad, pork kimchi stew, red pepper paste pork chops, beef bulgogi, grilled mackerel and saury stew. However, the soups and noodles showed significant differences between the control and the 15% reduced sodium (level 1) food groups, specifically in banquet noodle, seaweed soup, ahuk soup.

This study was conducted to compare the commercial noodle flours (n=8) of each milling company in Korea. Eight noodle flour samples were classified into two types of flours, all-purpose flour (AF, n=4) and premium noodle flour (PF, n=4) and tested using general component analysis. Texture assessment and sensory test for doughs and noodles were performed. The dough strength was positively correlated with lower ash content, smaller particle size and longer formation time. Sensory evaluation found that weaker cooked noodle strength correlated with higher scores in preference and softness. As a result, it can be suggested that PF is better than AF in noodle making because PF has lower ash content and smaller particle size than AF. As such, flour characteristics that produce noodle flour of uniform quality can be obtained by combining flours with the above processing characteristics to fit the qualities desired.

This study was carried out to investigate the nutrition knowledge, dietary attitudes, and dietary habits of girl's high school students in Kunsan, and to investigate their recognition of food-nutrition labeling. The results are summarized as follows. General nutrition knowledge is relatively low, with an average of 0.57. It was shown that high school female students skipped breakfast rather than lunch or dinner, with a skipping rate of 28.9% for breakfast, 0.7% for lunch, and 8.6% for dinner. Regarding snacks, 35.5% of all the surveyed students had 1 snack per day, with 31.9% having them between lunch and dinner. The most popular snacks include biscuits (22.3%), noodles (18.3%) and bakery (13.3%). The most popular response was that students 'sometimes checked' the food label of processed domestic and imported processed food. The level of satisfaction with food labels is moderate, with an average of 2.96, out of 5. The most satisfactory title about food labels was 'helpful for food selection' with 3.19. On the other hand, the least satisfactory title was 'understands the label' with 2.78. Regarding the identification of the nutrition labeling, the highest response was 'sometimes watched, sometimes not' with 40.5%. Products which were most often checked were milk/milk products (3.44), snacks/bread (3.33), and soft drinks (3.07). Among nutrition labeling items, total calories was the most important, followed by fat, carbohydrate, cholesterol and calcium. The question regarding the knowledge of nutrition labeling rated an average of 0.58 (out of 1). There was a significant positive correlation between the degree of the nutrition label verification and the dietary attitude score, along with the nutrition labeling knowledge and the nutrition knowledge score of the subjects. On the other hand, the degree of the nutrition label verification and the knowledge on nutrition labeling had a significant negative correlation. Hence, it is of the opinion that education on properly reading nutrient information is necessary to enable adolescents to apply that in real life. Furthermore, labeling nutritional information on processed fred through a more comprehensive method is deemed necessary as a supporting measure.
