The elderly population in Korea is rapidly growing. As the population ages, meals become a greater concern, as physical and psychological health problems are directly affected by dietary life, especially for the lower-income elderly. Although the government provides support through a free congregate meal service, there is a lack of systematic management of this meal service. This study investigates the experience of the elderly, especially the symbolic meaning and issues regarding the congregate meal service in their dietary life, to establish strategies for improving congregate meal services. Qualitative data was collected from ten elderly receivers of meal services through in-depth interviews and data was analyzed using Colaizzi's phenomenological research methods. Overall, 90 significant statements, 13 formulated meanings, and five theme clusters were deduced. The five theme clusters for the importance of meal services to the elderly included the followings: "a real meal", "enjoyment of living", "maintenance of regular life", "place for social life" and "meal of silence". We found that the elderly regarded the congregate free meal service not only as meals to appreciate but also as a form of social life. Furthermore, the elderly did not typically express any complaints regarding congregate meal services because they are free. The results showed that it might be difficult to evaluate the quality of meal services based on the opinions of the service receivers. This study suggests it is necessary to develop multilateral evaluation methods to reflect the needs of the elderly and to improve the congregate meal services at elderly welfare centers.

The purpose of this study was to evaluate food behavior in relation to the program of kindergarten and day care center as well as to identify problems which can be aroused there. We conducted the survey repeatedly, ten times among same 124 preschool children below 5 years old. The instruments were categorized into 3 different parts: part 1 for pre-meal food behavior, part 2 for mid-meal food behavior, and part 3 for after-meal food behavior. These were types of checklists which consisted of guideline of habit formation for daily life, especially food habit were developed on the basis of the National Kindergarten Curriculum. We Have reached the following results. $\circled1$ The group of below 3 year-old children had lunch and snacks more frequently than other age groups. $\circled2$ The children's age did playa role as one of the factors which influences on children's food behavior. The less frequency of taking meals in day care center the better their food behavior score. $\circled3$ Therefore, the age of children whose age is 3 or Jess spent more (of day) time at care center and had significantly more number of meals and snack at the care center. In such case, the food behavior was found to be not in good shape. I-ence, the children who were more exposed to feeding meal in kindergarten and day care center, were like to form unfavorable food behavior. The average food behavior score is significantly correlated with pre-mea, mid-meal, and post-meal food behavior. The study suggested that feeding program for young children at kindergarten and day care center should be systematized and developed on the basis of the status of their food behavior.

Studies were conducted with intact White Leghorn roosters to determine the true metabolisable energy (TME) and the true amino acid availability (TAAA) in five dehulled and hulled soybean meals produced in China. 60 roosters, kept in individual cages, were fasted for 48 h and then tube-fed 50 g of one of experimental feedstuffs and their excreta was then collected for the subsequent 48 h period. Two separate collection periods were used with each meal being fed to 12 roosters. The birds were given a 15-day recovery period between collection periods. An additional 12 roosters were either fasted or fed a protein-free diet in order to estimate the extent of endogenous losses of energy and amino acids in excreta. The average values per bird for nitrogen loss, endogenous energy losses (EEL) and endogenous energy losses corrected to zero-nitrogen balance ($EEL_n$) were found to be 0.74 g, 47.0 kJ and 21.5 kJ, respectively. It was found that the TME and TAAA values of dehulled soybean meal were higher than those of hulled soybean meal. The TME and nitrogen-corrected TME metabolisable energy values of dehulled soybean meal were 10.58 and 10.74 MJ/kg, respectively, while the corresponding values for hulled soybean meal were 10.03 and 10.27 MJ/kg, respectively. The average indispensable and dispensable amino acid availability of dehulled soybean meal was 92.1 and 93.5%, compared with 89.3 and 91.4% for hulled soybean meal. Dehulled soybean meal would therefore appear to be superior to hulled soybean meal as a source of protein and energy for use in poultry rations.

The present experiment was conducted to determine the digestible energy (DE), metabolizable energy (ME) content, and the apparent total tract digestibility (ATTD) of energy in growing pigs fed diets containing one of ten cottonseed meals (CSM) collected from different provinces of China and to develop in vitro prediction equations for DE and ME content from chemical composition of the CSM samples. Twelve growing barrows with an initial body weight of $35.2{\pm}1.7$ kg were allotted to two $6{\times}6$ Latin square designs, with six barrows and six periods and six diets for each. A corn-dehulled soybean meal diet was used as the basal diet, and the other ten diets were formulated with corn, dehulled soybean meal and 19.20% CSM. The DE, ME and ATTD of gross energy among different CSM sources varied largely and ranged from 1,856 to 2,730 kcal/kg dry matter (DM), 1,778 to 2,534 kcal/kg DM, and 42.08 to 60.47%, respectively. Several chemical parameters were identified to predict the DE and ME values of CSM, and the accuracy of prediction models were also tested. The best fit equations were: DE, kcal/kg DM = 670.14+31.12 CP+659.15 EE with $R^2$ = 0.82, RSD = 172.02, p<0.05; and ME, kcal/kg DM = 843.98+25.03 CP+673.97 EE with $R^2$ = 0.84, RSD = 144.79, p<0.05. These results indicate that DE, ME values and ATTD of gross energy varied substantially among different CSM sources, and that some prediction equations can be applied to predict DE and ME in CSM with an acceptable accuracy.

This study was conducted to investigate the digestibility of dry matter (DM) and nitrogen (N) in oilseed meals and distillers dried grains (DDG) fed to growing-finishing pigs. As experimental animals, eleven barrows (initial body weight, $71.7{\pm}17.0kg$) were housed in individual metabolism cages. The experimental design consisted of an $11{\times}8$ incomplete Latin square with 11 dietary treatments and 8 replication periods. The diets were individually formulated with dehulled soybean meal produced in Korea (SBM-KD), soybean meal produced in India (SBM-I), soybean meal produced in Korea (SBM-K), corn high-protein distiller dried grains (HPDDG), tapioca distillers dried grains (TDDG), canola meal (CAM), corn germ meal (CGM), copra meal (COM), palm kernel meal (PKM), sesame meal (SM), and perilla meal (PM). Pigs with SBM-KD and SBM-K showed greater (p < 0.05) intake of N than SBM-I, HPDDG, and PKM. Total feces output was decreased (p < 0.05) in SBMs (SBM-KD, -I, and -K), HPDDG, and CGM compared with TDDG, SM, and PM. The DM in excreted feces was decreased (p < 0.05) in SBMs and CGM compared to TDDG, SM, and PM. Similarly, the SM and PM fed to pigs resulted in greater (p < 0.05) fecal excretion of N than the others. Apparent total tract digestibility (ATTD) of DM in SBMs and CGM was greater (p < 0.05) than TDDG, SM, and PM. The SBMs fed to pigs showed higher (p < 0.05) ATTD of N than TDDG, COM, SM, and PM. In conclusion, our results provided nutritional information about various ingredients and would be useful to contain more precise amounts of nutrients included in feed ingredients of pig diet.

This study was conducted to illustrate standard menu items available in the school foodservice industry, and to establish higher nutritional standards in this industry. We reviewed menu items from 125 middle and high schools from the Seoul area for three months. These menus were then classified into 12 representative menu items, as follows: beef seeweed soup, egg soup, sliced rice rod soup, spaghetti, sauted squid with hot sauce, fish cutlet, simmered pork-egg in soy sauce, sweet and sour meat, sauted pork, acorn starch jelly salad, cucumber salad. And standard recipes of these 12 representative menu items were established, based on a survey from 150 dietitians who completed a questionnaire of 97 questions. According to the survey results, 89% of the dietitians answered positively('yes') about the necessity of establishing standard recipes for the school foodservice industry. 69% of the dietitians were educated standard recipes for the school foodservice, 91% will use standard recipes for the school foodservice Moreover, we discovered there was a consensus on what type of menu items should be included on the menus; demographic factors only affected a small range of recommended items. In order to confirm real application of resulted standard recipe, it is required to conduct quantity food production at real foodservice and study on more suitable standard recipe.

The purpose of this study was to investigate food preferences and dietary habits of university students in Kyungbuk province. We assessed anthropometric measurements, food preferences, and dietary habits of seventy nine male and sixty nine female students at K university. The results of this study were analyzed with $\chi$$^2$, t, and ANOVA test using SPSS package program. The percentages of students who were underweight, normal and overweight by body mass index (BMI) were 18.0, 22.1, and 27.7 for males, and 17.8, 21.7, and 28.7 for females, respectively. Preferences for noodles with bean sauce, bread (castella, red-bean bread), beef, pork, chicken, ham, garlic, milk soy bean milt carbonated drink ionic beverages, bun (fried, steamed), croquette, soju(alcohol) and tobacco were higher in males than females, but preferences for tangle, strawberry and orange were lower in males than females. Males did not skip meals compared to females, and ate more meat fat than females. Males exercised more frequently and longer than females. Eighty six point eight percent of females and 69.7% of males were dissatisfied with their weights, and females attempted the weight control more than males. Preferences for bibimbab(boiled rice with assorted mixtures), ionic beverages, and beer were shown higher in overweight males than in normal ones and preference for red fish, hamburger, and chocolate were higher in underweight females than overweight ones. Overweight females skipped meals more and ate more meat fats than normal weight ones. Normal weight males and underweight females were satisfied with their weight. The results of this study suggest that university students need more nutritional education, and modification of dietary habits based on food preference to prevent and treat obesity and to maintain their health.

This study examined Korean employees' meal structure characterized by mealtime, meal places, and companions. The data from 19,692 time diaries, recorded by 9,846 employees aged 19-64 years for two days in the 2014 Korean Time Use Survey, were analyzed for working days and non-working days. Approximately two-thirds of Korean employees ate meals three times a day on both working and non-working days. The breakfast and lunch-times on working days were distributed within two hours, but the dinner time on working days and all three meals on non-working days were dispersed across a three-hour range. Male employees spent three minutes on meal preparation on working days, whereas females spent 30 minutes. On working days, 88% of breakfasts and 67% of dinners were eaten at home. For lunches, 46% were eaten at restaurants, and 42% were at workplaces. The breakfast on working days showed the highest percentage of eating alone (40%) and the dinner on non-working days appeared highest in the percentage of eating with families (69%). The characteristics of Korean employees' meal structure appeared different on working days and non-working days. Such characteristics should be considered in the process of planning nutrition policies and programs for employees.

This study was conducted to find the differences in the physical changes, eating habits and dietary intake by obseity index of sixth grade primary school students is Seoul.The subjests were classified into three groups, an underweight group(90% under, 12l Ug), normal group(between 90-110%, 153, NG), and obese group(110% over, 91, OG) according to WLI(Weight-Length Index)calculated with their present (6th grade) height and weight. The physical growth of the subjects was generally good, although problems of both underweight and obesity were existed together. The mean heigh growth velocity per year, weight growth velocity per year and WLI changes per year of OG were higher than those of the other groups(p〈0.01). The past physical status of the three groups were maintained from 1 st grade to sixth grade, As eating habits and lifestyles, they were not statistically significant but there were some differences among the three groups. More students of the UG disliked a certain food than those of the other groups. UG liked fried or roasted foods more(p〈0.001). NG tended to eat three meals more irregularly. OG tended to have meal times more regularly and do more regular exercise than the other groups. The dietary intakes of three groups were generally good. They were not statically significant among the three groups. With theses difference among the three groups, it is recommended to educate about unbalanced diet for the underweight group, regularity, of meals for the normal group, doing exercise for the obese for the obese group, and increasing Ca and vitamin A intake for most students, As the physical status for th lower grades have been maintained up to the sixth grade, nutrition education programs should be started at the lower grades in the elementary school.

The purpose of this study was to obtain the nutritional values and objective data of uncooked powdered food (UPF) in korea. We interviewed 27 healthy female subjects aged over 25 years living in the lksan area. We just replaced common breakfast and dinner of the subjects with UPF. Their dietary intake status was evaluated by 24-hour recall method. Their body compositions were measured using body fat analyzer. Also we conducted hematological and clinical analysis of blood. The intake of energy, lipid and protein has decreased as people started to take UPF, but the intake of vitamins and minerals has increased. The quality of meals has improved after taking UPF. Due to the energy loss by taking UPF, weight and body fat gradually lessened. Among the lost weight the percentage of the body fat was high and we judged that the process of losing weight was successful. It is hard to predict whether weight loss will occur to people who are already in shape or not, but if overweight and obesity people regularly take UPF instead of other food products, we assume that UPF will help lessening body fat. The most positive change among biochemical changes by taking UPF was decreasing of serum lipid contents. The concentrations of total cholesterol and LDL-cholesterol gradually decreased and decreased intently after 12weeks. Serum HDL-cholesterol gradually increased and serum triglyceride showed gradual decrement. When healthy adult women replaced two of three meals with UPF for 3months, we were able to see some useful changes like decrement of body fat and serum lipid control and during this 3month period, no significant nutritional problems occurred. Complete judgement on UPF may be difficult with these conclusions but if people take a nomal meal once and replenish iron from taking UPF twice a day, we assume that replacing UPF with regular meal not be a problem in nutritional status. If other experiments on the effects of UPF proceed, we believe that those experiments will be very helpful in judging the nutritional value of UPF. (Korean J Nutrition 36(1) : 49-63, 2003)
