BACKGROUND/OBJECTIVES: This study aimed to investigate the association of dietary patterns with overweight risk and all-cause mortality in pediatric cancer patients. SUBJECTS/METHODS: Prospective cohort study was undertaken; 83 cancer patients admitted to the pediatric cancer ward at a university hospital in Seoul were included and followed for obesity and death over 24 months. Food consumption data were collected from patients using validated meal order sheets for breakfast, lunch, and dinner at the pediatric cancer ward over 3 days. Using principal component analysis, three dietary patterns were derived from 29 food groups. RESULTS: Eighteen deaths occurred among the patient cohort during the follow-up period. The "spicy & fried meat and fish" dietary pattern was positively associated with overweight risk at both baseline [odds ratio (OR) = 4.396, 95% confidence interval (CI) = 1.111-17.385, P for trend = 0.023] and after 6 months (OR = 4.088, 95% CI = 1.122-14.896, P for trend = 0.025) as well as all-cause mortality (hazard ratios = 5.124, 95% CI = 1.080-24.320, P for trend = 0.042), when comparing the highest and lowest tertiles after adjusting for covariates. The "fish, egg, meat, and fruits & vegetables" dietary pattern was associated with lower overweight risk after 24 months (OR = 0.157, 95% CI = 0.046-0.982, P for trend = 0.084). CONCLUSION: The results imply that dietary patterns might be associated with weight gain and premature death among pediatric cancer patients.

Urban agriculture, which promotes communication in vulnerable classes and the formation of social networks has been gaining attention with an emphasis on healthy city, elderly-friendly city, safe city and happy city as future keywords about urban life. There is a growing interest in public awareness in many areas such as health, society, economy, and ecology. As an attempt to improve the diversity of urban gardens, this study begins with collecting suitable crops for urban gardens from "Imwongyeongjeji (林園經濟志)," an encyclopedia written by Yoo-Ku Seo, a scholar in the 18-19th century. Out of those recorded in "Gwanhyuji (灌畦志)," 128 kinds of crops with linkage of the historical achievements of the realists who gave their priority to public welfare were selected and 53 crops which had traditionality, historicality, health functionality and popularity were finally selected. The properties (cold, warm, clam) of the selected crops were evenly distributed, and there was no crop that was hot and cool. In addition, the number of crops that have a sweet taste was the highest, followed by spicy and bitter, but there was no salty vegetable, which can be attributed to the fact that 12 namuls (wild vegetables) that grow in seas were excluded in this study since they were not suitable for urban gardens. Urban gardens can be transformed from those that focus on primary production and secondary consumption activities into a new resource that offers educational and traditional values by applying humanities to urban agriculture as a content resource in the era of cultural consilience and convergence. It is expected to satisfy urban residents' intellectual and participatory needs and to enhance the diversity and utility of urban gardens by applying traditional knowledge to a new model of urban agriculture. We hope that further research will be conducted to develop new types and models of urban agriculture going forward.

This study was performed to investigate menu preferences of adult customers for Korean food made from Korean traditional sauces. A total of 962 valid responses were used for data analysis. Statistical analyses were conducted using the SPSS package program (ver 20.0). The results of this study are summarized as follows: overall preferences were highest for braised spareribs, followed by braised short ribs, grilled beef ribs, and bulgogi. On the other hand, overall preferences were lowest in eggplant namul, followed by squid and radish soup, and grazed lotus roots and burdock. Female's overall preferences were significantly higher than male's for nine menu items, including japchae and seasoned acorn starch curd with vegetables, whereas male's overall preferences were significantly higher than female's for 19 menu items, including grilled deodeok and frozen pollack stew. Moreover, the menu item that was most significantly preferred was soybean sprouts soup in subjects aged under 20 years and Korean meatballs in subjects in their twenties. Subjects in their forties showed significantly higher preferences for 15 menu items, including braised hairtail, grilled deodeok, and seasoned and grilled yellow corvina compared to other age groups. Furthermore, menu preferences of production service workers were significantly higher than other groups for frozen pollack stew, loach stew, grilled dried pollack, steamed dry pollack, dried pollack soup, eggplant namul, and seasoned and grilled yellow corvina, whereas menu preferences of official professional workers and students were significantly higher than those of production service workers for braised short ribs, grilled beef ribs, seasoned and simmered chicken, mixed noodles, Korean meatballs, stir-fried rice pasta with vegetables, spicy soft bean curd stew, japchae, mung bean jelly mixed with vegetables and beef, bibimbap, and stir-fried squid. The results show that menu preferences of adults customers differed depending on gender, age, and occupation. In conclusion, the results of this study should provide foodservice managers with information about menu planning for target customers of commercial or non-commercial foodservice cafeterias and recipe development of low-sodium Korean foods.

Electron spin resonance (ESR) spectroscopy was used to detect radiation-induced signals from irradiated spices and ESR parameters were analyzed to define specific signals. Four powdered spices (red pepper, garlic, onion, and black pepper) were irradiated with 0, 1, 5, or 10 kGy at room temperature using a [60Co] gamma-ray irradiator prior to ESR analysis. Radiation-induced triplet signals, including those from the cellulose radical, which are center signals ($g_2=2.00673$) within the range of 3.0455 mT, were observed in all irradiated spice samples. The parameters g-value, center field, and signal range of hyperfine triplet ESR signals were constant in all irradiated samples, being specific for cellulose radicals and thereby distinguishing these signals from those of nonirradiated control samples. High positive correlation coefficients ($R^2=0.8452-0.9854$) were obtained between irradiation doses and corresponding ESR signal intensities. Thus, reliable detection of irradiated dried spices by measurement of ESR cellulose signals was confirmed by parameter analysis for the cellulose radical.

This study was conducted to devise a scheme for the development of foods designated as Yookmee (“6 dishes), which are representative food of Daejeon area. The Yookmee consist of Seolleongtang(ox bone soup and boiled rice), Samgyetang (chicken stew stuffed with glutinous rice and ginseng), Dolsotbap (boiled rice mixed with vegetables), Goojeukmook (acorn jelly), Sootgol-naengmyeon (cold buckwheat noodles with broth) and Daecheongho minmulgogi-maeuntang (spicy hot freshwater fish soup). A questionnaire was developed and administered by means of an interview regarding the subjects' recognition of and preference for the six dishes, their usual eating places and eating frequencies, the need for some standardization of recipes and for nutrition labeling including serving sizes and nutrient content. The total number of subjects who participated in this study were 328 (male 112, female 216) living in Daejeon. The subjects who were aware of the presence of Yookmee were more in their thirties or older (15%) compared to those in their twenties (9.6%) The percentages of the subjects who recognized the Yookmee as the representative foods were twice among those in their thirties (over 60%), as compared to 31.5% in their twenties (p<0.001). Samgyetang was one of the favorite foods of all the Yookmee among those in their twenties and Goojeukmook was the favorite for all the other age groups. The incidence of those eating one of Yookmee more than once a month was 51.5% in all the age groups, but the intake frequency was lower among those in their twenties (43.8%). The percentage of those who recommended Yookmee as a food for guests was the highest among those in their fifties (54.7%). The first reason why the subjects do not recommend these foods was because they were unfamiliar with Yookmee; among those in their thirties and forties the 2nd reason was because it is not much enough in quality or quantity to be served as a food for guests. Over 60% of the subjects felt the need for standardization of Yookmee, recipes for especially those in their fifties did feel the needs (92.5%). Furthemore, regarding labeling of sowing sizes and nutrients contents, over 80% of the subjects wanted these, and this desire tended to increase with age. From these results, it seems reasonable to accept Yookmee as the representative foods of Daejeon, despite the fact that many people do not yet currently do so. Since most of the subjects (85.4%) partake Yookmee outside of their homes, it is recommended that efforts need to be expanded on enhancing the nutritional quality, the taste and the quality control of Yookmee by standardizing the recipes, labeling the serving sizes and nutrient contents, and providing educational and publicity programs.

Objectives: This study examined the effects of nutrition education focused on personalized daily energy requirement and food units using Food Exchange System on anthropometric, biochemical characteristics, nutrition knowledge, dietary attitude and nutrient intakes for overweight and obese in a public health center. Methods: The subjects were 60 overweight/obese women based on BMI (educated 30 vs. non-educated 30, 50~64 years). Educated group was provided individual and/or group lessons (40 min/lesson/week, 5 week), 'Introduction: obese & health', '6 nutrients and 6 food groups', 'My obesity & daily needed energy', 'Meal planning for personalized daily energy and food units using Food Exchange Systems', and 'Smart food choices'. After education, we examined the differences in anthropometric/biochemical characteristics, nutrition knowledge, dietary attitude and nutrient intakes between educated group and non-educated group. Results: After nutrition education, in the educated group, there were improvements on anthropometric/biochemical characteristics, nutrition knowledge, dietary attitude and nutrient intakes in the educated group compared to the non-educated group. We observed a decrease in the mean weight, total cholesterol (TC) and the incidence of overweight/obesity and hypercholesterolemia and an increase in the mean lean body mass. The scores of nutrition knowledge, 'Function of carbohydrate, protein, vitamin, mineral' and 'Food Sources of fat, vitamin, mineral' were increased. The scores of dietary attitudes, 'Taking a joyful meal, a leisurely meal, a balanced meal, a meal with sufficient vegetables, a meal with diversity, a meal with spicy foods, a meal with overeating' were increased. The intakes of energy, carbohydrate, fat, protein, vitamin A, thiamin, Zn and cholesterol were decreased. The scores of INQ, protein, vitamin A, vitamin C, thiamin, riboflavin, vitamin B6, folate, Ca, P, Fe, Zn were increased. Conclusions: The nutrition education focused on personalized daily energy requirement and food exchange unit using Food Exchange System for overweight and obese may improve food behavior, dietary intakes and symptoms of overweight and obese, even in a community health center.

The identification characteristics of inadiated dried onion and garlic at 1, 4 and 7 kGy were investigated by analyzing their photostimulated luminescence (PSL), thermoluminescence (TL) and electron spin resonance (ESR). The PSL results showed that the photon counts of non-irradiated dried onion were less than 700 (negative) and those of irradiated samples at 1kGy or more were over 5000 (positive), making it possible to discriminate non-irradiated onions from irradiated ones. However, the intermediate counts (700-5000) were observed in irradiated garlic at 1 and 4 kGy, even though positive counts were measured in 7 kGy group. Radiation-induced TL glow curves $(TL_1)$ were measured at $150^{\circ}C$ range in both irradiated onion and garlic samples at 1 kGy or more, which could identify irradiated groups. Furthermore, determination of TL ratios $(TL_1/TL_2)$ for both samples could verify the above results. It was found, however, that ESR spectroscopy was not suitable for the detection of irradiated dried onion and garlic.

A secondary survey was conducted of 503 customers, to investigate eating out behaviours at five fast food restaurants of Youido apartment compound in Seoul, in April of 1988. The results are summarized as follows: The majority, 84% of customers, were aged 14 to 30, consisting of junior and senior high school children, college students and company employees. In contrast to the previous survey of 1986, in which no elderly customers were found, a small number of elderly customers were observed in this study. The reasons given by customers for patronizing fast food restaurants were the following, from most to least frequent: 'convenient', 'allows for companionship', 'the pleasant place to eat', 'dining equipment and tableware are hygienic', 'to be able to stay as long as I want', and 'foods rapidly served'. Only 24.2% of the customers purchased the fast foods for a full meal, 38.3% purchased the foods for snacking, and others purchased ice cream only or drink only. The majority of the customers ate the purchased foods at the fast food restaurants. However, a limited number of female customers preferred to take the packed fast foods to their homes. Taste preference was a major factor in food selection from available menu items, among the younger customers; whereas customers over 30 years old were concerned with nutritive balance. Fried chicken, pizza, rolled rice with laver, ice cream, and juice were high on the list of liked foods; in contrast, lower preference was for fish burger, doughnut, spaghetti, Chajang noodles and chili beans. The survey discovered that the preference for fried chicken, pizza, and salad had increased compared to the previous survey of 1986. Preference by food nationality was highest for Korean food, then Western food, Chinese food, and Japanese food, in that order. Customers offered suggestions for better fast food service, such as lowering the price; greater variety in the menu; developing fast foods from the traditional Korean foods; and increasing the proportion of vegetables and fruits on the fast food menu. The customers, in particular, emphasized a need for the development of Korean traditional beverage of malt drink and persimmon punch, as well as mungbean pan cakes and sweet- spicy rice noodles (docbokki), as fast foods.

Red pepper is widely used as a spicy flavor ingredient in the food industry and many households. The objective of this study was to assess the total aerobic bacteria count, coliforms count and incidence of Escherichiacoli, Salmonella spp., Escherichiacoli O157:H7, Listeria monocytogenes, and Bacillus cereus in red pepper and red pepper cultivated soil. The total aerobic bacteria number in red pepper and soil were in the range of 2.97 to 8.13 and 5.91 to 7.65 log CFU/g, respectively. The coliforms in red pepper and soil were in the range of 1.87 to 6.71 and 0.67 to 6.16 log CFU/g, respectively. E. coli was detected in 3 of 54 soil samples. In 3 out 63 red pepper and 53 of 54 soil samples, B. cereus was detected, while Salmonella spp., E.coli O157:H7, and L.monocytogenes were not detected. The results from this study provide an important basic information associated with the microbiological safety of fresh vegetables. Continuous caution is needed to prevent the contamination of pathogenic microorganisms during its farming.

Purpose: This study compares the snacking pattern, diet, lifestyle, and food preference of children by evaluating the most frequently eaten snacks. Methods: The survey enrolled 435 students from three elementary schools in Gyeonggi. Based on the most frequently eaten snacks, the subjects were divided into 3 groups: fruits and milk/dairy products for natural snacks (NS, n = 114); noodles, snack foods and fast foods for meal-like snacks (MS, n = 74); cookies, beverages and bread as sweet snacks (SS, n = 247). Results: Compared to the MS group, preferences of the NS group were significantly higher for jabgokbap (cooked rice with multi-grains, p < 0.05) and saengchae (seasoned raw vegetables, p < 0.01), and significantly lower for gogitwigim (deep-fried meat, p < 0.05). Taste preference of the NS group was considered to be more desirable; the taste preference of more subjects was 'sweet taste' in the SS group, 'spicy taste' in the MS group, 'salty taste' in the MS and SS groups, and 'sour taste' and 'bland taste' in the NS group than the other groups. Compared to the MS and SS groups, the NS group was determined to exercise more frequently; exercising for more than 30 minutes/day was determined to be 76.3% in the NS group and 58.1% and 57.9% in the other groups (p < 0.01). Moreover, a higher proportion of subjects in the MS group tended to answer 'not hungry' as the reason for leaving school meals, as compared to other groups (p = 0.055), thereby suggesting that inappropriate snacking habits interfere with regular meals. Conclusion: This study provides evidence that healthy snacking habits, which include natural snacks such as milk/dairy products and fruits, are important for children during the elementary school years, since these habits are associated with healthier diet, lifestyle, and food and taste preferences. These results provide basic information for developing nutritional education materials for elementary school children.
