  • Physicochemical properties and mineral compositions of seaweed salts prepared with various seaweeds and concentrated sea water were determined. Ash content of sea mustard was highest (22.7%) and that of laver the lowest (9.8%). Sea mustard contained high amount of Na, while sea tangle and seaweed fusiforme contained high amounts of K and Ca. When insoluble solids were removed after incineration of dried salt, surface color of the salt whitened more due to increase in salt purity with resulting decreases in pH and oxidation-reduction potential (ORP), pH and ORP of the ashed salt decreased, and K and Ca contents increased, while Mg content decreased. Yield of seaweed salt was the highest in sea mustard, ORP was lowest in sea tangle and seaweed fusiforme, and K and Ca contents increased significantly in sea tangle and seaweed fusiforme salts. As the concentration of sea water increased, yield and purity of the salts increased with decrease in pH and ORP and increase in Ca and Mg contents. Seaweed salt showed the characteristic crystalline structure as viewed by SEM.

  • The purpose of this study was to investigate the prevalence and to identify the related factors of overweight among young children. The study subjects were 138 children, aged 3-5, attending child care centers in the Kyungbuk area. We assessed a wide range of collected variables including general characteristics, anthropometric data, dietary habits, stress, food preferences, and food frequencies of young children, and anthropometric data and general characteristics of their parents. The results of this study were analyzed with $\chi$$^{2}$_ or t-test using SPSS package program. The subjects were classified into two groups using the weight for length index WLI criteria: normal group(n=101) and overweight group(n=37). Forty-nine percent of mothers of overweight children did not recognize their child's current overweight status. Scores for encountering criticized-violent situation stress, hurt-pride stress and total stress were higher in the overweight group than in the normal group. The frequency of snacking and the appetite of the overweight group were increased compared to those of the normal group. The overweight group had higher preferences for salad, kimbab, boiled rice with meat, vegetables and Chinese noodles, chicken, shell, banana, soybean milk, hotdog, and potato than the normal group. The overweight group showed higher consumption frequencies of pan-fried foods, egg, laver and strawbery compared to the normal group. Therefore, our results suggest that obese young children, as well as their parents, need more nutritional counseling education about dietary habits, food preference, recognition of normal weight and strategies for actively coping with stresstopreventandtreatobesityandtomaintainhealth. .

  • The purpose of this study was to assess the frequently consumed dish consumption frequencies of continuous ambulatory peritoneal dialysis(CAPD) patients with osteopenia and develop recipes to improve bone mineral density of CAPD. The subjects were 96 CAPD patients with osteopenia(male 39, female 57) (osteopenia group) and 45 CAPD patients with normal BMD(male 24, female 21), matched with key variables(normal group). Fifty dishes(foods) that most frequently consumed were determined and food consumption frequency for each dish(food) for two groups were compared. Osteopenia group showed lower consumption frequency for ice-cream but higher frequency in apple. Of the 50 most frequently consumed dishes(foods), 20 dishes assessed as safe and recommendable for CAPD patients with osteopenia based on the contents of protein and mineral were selected : white boiled rice, white gruel, beef soup, steamed cabbage, roasted dried laver, fried egg, roasted bean-curd, cooked and seasoned bean sprouts, corn-starch jelly, cheese, ice-cream, orange juice, apple, grape, peach, peanut, raw lettuce, raw cucumber, and injulmi rice cake. wenty eight new dishes with modified recipes were developed for CAPD patients. Protein and mineral contents were analyzed for frequently consumed 17 dishes, assessed as modification of recipes are needed. The recipes were modified to decrease P, Na and K contents and to increase protein and Ca contents. Twenty dishes(foods) selected as having reasonable protein and mineral contents ratio or 28 newly developed dishes modified with protein and mineral contents or ratio would be helpful for nutrition education or counseling for CAPD patients with osteopenia. Dishes(foods) suggested in this study would also be useful for all CAPD patients for preventing osteoporosis.

  • Acculturation may manifest dietary behavioral changes of students from overseas. This study investigated the dietary attitudes, food intakes, and dietary behaviors of 121 Chinese college students residing in Busan, Korea. Using a focus group interview and structured survey, subjects were divided into two groups (SG, LG) based on their self-rated acculturation status. The SG (n=70) and LG (n=51) groups consisted of participants that had resided in Korea for shorter than 18 months versus 18 months or longer, respectively. The SG group was more likely to point out the taste of Korean foods as being too sweet, salty, and spicy but less greasy. A food frequency questionnaire was developed to assess normal intake of Korean ethnic, Chinese ethnic, and common foods. The LG group consumed more Korean foods such as rice cake, dried laver, and radish kimchi but less Chinese foods such as bread glue ball and kidney bean. The LG group consumed more salty and fatty foods and Korean liquors, whereas the SG group consumed more fruits and noodles. Based on the exploratory factor analysis, the SG group showed significantly higher scores for "dietary regularity" but lower scores for "indulgence of unhealthful food" factors. In summation, the LG group became more accustomed to Korean foods and adopted less desirable dietary behaviors compared with the SG group. Findings suggest that the residential period of Chinese college students may be associated with their self-rated acculturation status and food acculturation process, and therefore tailored nutrition education programs are needed to support Chinese students' healthier dietary behaviors and food acculturation process.

  • Korean food habits, dietary behaviors and perception of food were compared according to gender and age. The subjects were composed of 274 males and 315 females. According to age, the age group of 10s was 26.3%, 20s 24.6%, 30s 16.8%, 40s 18.7%, and 50s and over 13.6%, respectively. The majority (65.2%) of all age groups except the 20s took meals 3 times a day and the ratio 20s eating twice a day was higher than other age groups. All age groups took cooked rice(bap) two or three times a day and the 20s group took smaller amount than other age groups did. The younger age groups of 10s and 20s took larger amount of processed food. The older age groups appeared to have higher frequency of eating fish, bean, vegetable, Kimchi, laver.brown seaweed, soybean oil, sesame oil, coffee, tea, and rice cake(ddhuk). The younger groups have the higher frequency of eating ramyeon, corn flake, milk, milk-processed food, butterㆍmargarine, ham.sausage, carbonated drink candyㆍchocolate, hamburger, and pizza. All age groups perceived cooked rice(bap), meat, fish, egg, vegetable, fruit, and Kimchi to be the delicious, excellent and healthy food. According to the above results, age groups of 30s and over had relatively better food habits compared with those of younger groups. On the other hand, the groups of 10s and 20s had meals irregularly, showed a high ratio of skipping meals, and took processed food much. These results raised a concern of their nutritional imbalance in the future. Therefore, the correct nutritional education must be conducted to make these age groups have a healthy food habits.

  • Enterobacter sakazakii, designated as an unique microbial species in 1980, may cause bacteremia, necrotizing enterocolitis and infant meningitis. The distribution and the thermostability of E. sakazakii in unprocessed ready-to-eat (RTE) agricultural products of 252 and in 25 powdered infant formulas (PIF) were analyzed. Eighty one, 50, 43, and 47% of brown rice, pumpkin, potato, and carrot samples, respectively, had aerobic plate counts (ARC) in the range of 5 log CFU/g or more. Almost all the other products sampled had APC of approximately 2 log CFU/g. Fifty three, 75, 67, and 68% of banana, pumpkin, soybean, and carrot had Enterobacteriaceae counts approximating 3 log CFU/g. Sixty six percent of the brown rice tested had Enterobacteriaceae counts approximating 5-6 log CFU/g. E. sakazakii was isolated from 3/25(12%), 4/23(17%), 1/24(4%), and 1/27(4%) of PIF, brown rice, laver, and tomato samples, respectively. D-values were 3.52-4.79 min at 60 and $D_{60}-values$ were similar as the isolates reported. Thermal inactivation of four thermovariant E. sakazakii strains during the rehydration of PIF with hot water were investigated. At $50^{\circ}C$, the levels of E. sakazakii decreased one log CFU/g for 4-6 min and thereafter the levels remained stable for 20 min. At $60^{\circ}C$, inactivation by about 2 log CFU/g occurred for 20 min. Therefore, the unprocessed agricultural products might be a source of contamination for PIF when used as an ingredient after drying and pulverization. Rehydration of PIF for infant feeding with a water temperature of $60^{\circ}C$ rather than $50^{\circ}C$, as recommended by the manufacturers, may be helpful in the reduction of potential E. sakazakii risk.

  • This study was conducted to compare families eating-out behavior in relation to family life cycle in order to provide basic information on nutritional education about eating-out. The data were collected by the survey method from 440 families who lived in apartment complexes in Kyong-ju and Seoul. The structured questionnaire included items about the frequency of eating out, the choice of eating-out menus, the decision maker of the eating-out process, the attitudes toward eating out and the general characteristics of the families. The major results are as follow: 1) In the cafe of telephone delivery service, and eat-in restaurants, the subjects showed statistical significance (p < 0.01). With respect to telephone delivery service, families in Step II used it most frequently, but families in Step I rarely used it. With respect to eat-in restaurants, families in Step II used them most frequently but families in Step IV rarely used them. 2) In all the family life cycle steps, the most favorable menu was fried chicken for take-out type, Chajang noodles, fried chicken and pizza fur telephone delivery, pizza for internet delivery, raw fish and beef for eat-in restaurant, Docbokki, laver rolled rice and ramyun for convenience flood stores. 3) The wife was most influential in making decisions about the take-out type (p < 0.001). In the case of telephone deliveries (p < 0.001), the wife was the most influential in the families of Steps I and II, but the children were the most influential in the families of Steps III and IV. In the case of eat-in restaurants (p < 0.001), the husband had the most effect on the decision-making process. In the case of convenience flood stores (p < 0.001), the children were the most influential in the families in Steps III and IV. In most family life cycle steps, each of them chose their own meal. 4) from a factor analysis perspective, attitudes toward eating out have been grouped according to two factors, namely 'Advantage' and 'Nutrition'. No factor showed a significant difference among the family life cycle steps.

  • As a disease that reduces quality of life, functional dyspepsia (FD) is associated with foods that may worsen its symptoms or cause it. The purpose of this study was to examine the nutritional status and dietary behaviors of FD patients. We investigated food intake, food intake frequency, and dietary habits of 45 FD subjects according to the Rome III Diagnosis Criteria. Average age and body mass index (BMI) were 47.7 years and $22.6kg/m^2$ (males: $23.4kg/m^2$, females: $22.1kg/m^2$), respectively. Average energy intake was 77% of Korean Dietary Reference Intake (KDRI), and it was less than that of the Korea National Health and Nutrition Examination Surveys (KNHANES). Other nutrient intake levels were similar to the KNHANES. Energy intake proportion of carbohydrates : protein : fat was 56 : 18 : 26, and the ratio of fat intake was higher than that of the KNHANES. Beans, laver, tomato, and yogurt were consumed very frequently. In the results of meal regularity, dietary behaviors and composition of diet were relatively good. It is likely that the patient controlled their diet by eating cautiously and by reducing alcohol drinking and smoking. Our results indicate that FD patients' nutritional status by consumption of nutrients was at a level of normal healthy people and that dietary habits were better than normal adults. However, their fat intake levels were somewhat higher than normal people. Therefore, further research is required to identify the relationship between dietary intakes and FD.

  • Objectives: Intake of fruits and vegetables has protective effects against stroke attack. This study intended to examine the status of consuming fruits and vegetables and to find out which factors may influence the frequency of consumption of fruits and vegetables in individuals with a history of stroke. Methods: The data of 208 subjects from 5th (2010, 2011) Korea National Health and Nutrition Examination Survey (KNHNES) who reported a stroke diagnosis was used for analysis. To identify major factors influencing the consumption of fruits and vegetables, a classification-tree analysis was carried out. Results: Among those who reported a stroke diagnosis, the frequencies of consumption of fruits and vegetables were influenced by their age, place of residence (urban or rural), economic status, educational level, occupation, number of family members, frequency of eating out, and having meals (breakfast or lunch) with family members. Two factors from fruits and three factors from vegetables were generated by exploratory factor analyses. Urban residents ate fruits and vegetables more frequently in all factors than rural residents. Eating frequencies of 'seasonal fruits (orange, apple, strawberry, melon, pear and watermelon)', 'easily-accessible fruits (persimmon, tangerine, grape, peach, banana)', and 'Western-style vegetables (cabbage, mushroom, carrot, tomato, spinach)' were influenced by the socioeconomic status. Eating frequencies of 'Korean-style vegetables (bean sprout, radish leaves, pumpkin/squash, sea weed)', 'preserved vegetables (Korean cabbage, radish, laver, cucumber)' were influenced by having breakfast with family members. Conclusions: The results of this study suggested that by eating more fruits and vegetables, more preventive effects against secondary stroke attack are expected in stroke patients who live in the rural areas and who do not eat breakfast with family members. In addition, more outreach and education programs are needed for them.

  • Objectives: This study was designed to find out factors that are needed to be improved for the Buddhist training environment of Sramanera Sramanerika monks, who have been newly adapted for their life style after becoming a monk, and to provide basic data for the development of the standard diet in Buddhist temples. Methods: A self-administered questionnaire was applied to 365 Sramanera Sramanerika monks at 11 Buddhist monk universities. The questionnaire was designed to investigate their dietary habits, dietary evaluation, satisfaction of food service, and food preferences. Results: The study population consisted of 52.6% men, and 47.4% women. The subjects who had a vegetarian diet before joining the Buddhist priesthood were 27.7% women, and 13.5% men (p<0.01). 42.2% of the total subjects felt that they are healthy now and 19.4% felt weak. The most difficulty of dieting adaptation as soon as entering the priesthood was the strict diet rules (42.9%). The subjects considered health or nutrition (40.0%) highly when having meals. 94.8% women, 84.1% men ate breakfast every day (p<0.001). Women (55.4%) frequently ate snacks more than men (26.6%) (p<0.001). The results of the dietary evaluation indicated that the intake of milk, soy milk or dairy products and beans or tofu received lower than 3 points and women had lower point result than men (p<0.001). Foods with higher preference were grilled mushrooms, grilled laver, miso stew, sweet and sour mushrooms, steamed tofu with seasoning. Conclusions: Women were more interested in their health than men but they also required to improve the nutritional eating habits. It appeared that the lower intake rates of the calcium containing food (milk and dairy), and proteins (beans and tofu) could result in nutritional imbalance. Therefore, it is necessary to offer food based on the standard menu plan with consideration given to their food preferences in order to maintain their health and desirable dietary habits.
