A $2{\times}3$ factorial design was used to study the impact of rearing systems, individual (I) vs. group (G) and different levels of milk/skim milk feeding (three schedules, F1, F2 and F3) on performance of crossbred (Bos indicus ${\times}$ Bos taurus) calves. Six calves (three from each sex) were taken in each group on the basis of their birth weight. All the calves were fed colostrum for three days and thereafter, were allotted to three different milk feeding schedules (F), i.e. milk fed upto 8 weeks of age (F1), milk upto 4 weeks followed by 50% (F2) and 100% (F3) replacement of milk with skim milk in the next 4 weeks. Calf starter and cereal green fodder were fed ad libitum to all the calves beginning from second week of age. A digestibility trial was conducted at 15th week of age to assess nutrient utilization during postweaning period. The digestibilty of dry matter (DM), organic matter, total carbohydrate, ether extract and crude protein (CP) were nonsignificant between the rearing systems and the feeding schedules. There was significantly higher digestibility of NDF and ADF in G than I and in F3 than F1 and F2. The concentration CP and total digestible nutrients of the diet ranged from 17.18 to 17.75% and 66.32 to 70.14%, respectively. The DM intake (kg/100 kg body weight) ranged from 1.74 to 2.14 kg during 0 to 8 weeks and 3.19 to 3.41 kg during 0 to 14 weeks of age. The effects during postweaning phase (9-14 weeks of age) showed increased performance in group housed calves compared to individually housed ones with a superior average daily gain (590 vs. 443 g) and dry matter intake (1.79 vs. 1.64 kg). Above all, replacement of milk with skim milk at 50% level after 4th week followed by complete removal after 6th week of age (F2) seemed to suit better in coping with immediate energy starvation due to sole feeding of skim milk (F3) and they performed the best under group housed system of rearing.

This study was conducted to assess macro- and micronutrient compositions in school lunch menus based on the 'Dietary Guideline' for School Lunches. Ninety-five dieticians in elementary school in Chungbuk were asked to complete a questionnaire on characteristics of the school lunch program(such as type of foodservice, food production system), the information about dietitians(such as age, education, and job history), and the extent of the use of processed foods and frozen foods. Dey were asked to return the questionnaire with the menus including the name and the quantity of every food ingredient offered during a week. A total of 554 lunch menus provided for a week of June 2004 were analyzed. Average nutrient content per meal was as follows; 660kcal, energy; 92.9g, carbohydrate; 26.7g, protein; 21.1g, fat; 287 ${\mu}gRE$, vitamin A: 0.5mg, thiamin; 0.5mg, riboflavin; 29.3mg, vitamin C: 338.2mg, calcium; 3.9mg, iron; and 97mg, cholesterol. Average percentages of energy from carbohydrate, protein and fat was 56.2%, 16.2%, and 29.0%, respectively. The mean nutrient content per meal was higher in rural-type than in urban-type schools. The weekly menu of 40% of the schools provided <55% of energy from carbohydrate, and 39% of the schools offered lunch that provided ${\geq}30%$ of energy from fat. The micronutrient content was generally high when the percent energy from fat was less than 25%. Our results showed that only 52.6% of the schools provided lunches with the energy composition as in the 'Dietary Guideline' of School Lunches. Whole Milk was the major contributor to fat, saturated fatty acid and cholesterol. We suggest that school foodservices start to provide low fat milk instead of whole milk to reduce fat, saturated fatty acid and cholesterol. If low fat milk is served instead of whole milk, percentage of energy from fat and saturated fat can be reduced from 29% to 25%, and ken 10.2% to 9.1%, respectively, and cholesterol could be reduced from 97mg to 79mg. Efforts to meet 'Dietary Guideline' for School Lunches should be made, especially to reduce fat intake, while maintaining essential nutrient intake at sufficient levels for childen.

This study was carried out to assess the food habit index of the long-lived elderly who were aged over 85 years living in Ganghwa-gun. A survey was conducted during December 2003. Dietary nutrient intake data was obtained through the 24-hr recall method. The subjects were 96 (32 males, 64 females) aged people and divided into three groups based on food habit index scores. Such as group A: good $16\∼20$, group B: fair $11\∼15$, and group C: poor $5\∼10$. The three groups of the subjects were 90.7 years of age and $21.3\;kg/m^{2}$ of BMI on average. Healthy eating index scores of the subjects were $9.4\%$ in group A, $54.2\%$ in group B and $36.5\%$ in group C. Their level of education were lower and their levels of living standards tended to have been middle and lower of the middle class. The percentage of living together with their families or spouses in all groups were over $60.0\%$ and the rates of the subjects who have responsibility for their meal preparations were also very high in all groups. Most subjects tended not to drink nor smoke, and spend $8\~10$ hours for their sleep. The percent of number of diseases in group A was lower than in groups B and C. Their dietary habits such as taking three meals a day regularly have shown that they have good eating habit in general. There was a positive correlation between the eating behaviors and nutrient intakes. The protein, animal protein, fat, PUFA, vitamin E, vitamin $B_{2}$, niacin, P and K intaks in group A were significantly higher than that of the groups B and C. For group A of good food habits aged had no sufficient intake of Ca and vitamin A than the Korean RDA and long-lived elderly of group C in Ganghwa areas had worse nutrients intakes, especially Ca, vitamin A, vitamin $B_{2}$ and vitamin E. According to this research having a good eating habits could be considered as increasing of the health and nutritional status. (Korean J Community Nutrition 10(6) $892\∼904$, 2005)

Objectives: The purpose of this study was to investigate effects of nutrition education providing school lunch by personalized daily needed food exchange units using Food Exchange System for adolescent athletes. Methods: The subjects were 60 sports high school students (educated group, 30 vs. noneducated group 30). Nutrition education was provided for 4 weeks (40 min/lesson/week). In addition, personalized school lunch was served for 4 weeks, nutrition education period. The personalized lunch were provided Food Exchange Units according to personalized daily needed energy. The lessons were '5 Major nutrients, functions and foods', 'My daily needed energy and food exchange units by Food Exchange System', 'My meal plan by food exchange units according to my daily needed energy' and 'Smart choice of healthy snacks and eating outs'. After nutrition education, we examined the differences in anthropometric characteristics, nutrition knowledge, dietary attitude and dietary intake between the educated and the non-educated group. Results: We observed improvements in lean body mass in the educated group. With regard to nutrition knowledge, there were improvements in 'Functions of vitamins', 'Functions of minerals', 'Foods of fat', 'Foods of vitamin', and 'Foods of mineral' in the educated group. In relation to dietary attitude, there were improvements in 'Taking a meal with family and friend', 'Taking a meal at ease', 'Taking a meal with kimchi and vegetables', 'Taking a meal with three kinds of side dishes', 'Priority of choosing snacks' and 'Type of snacks' in the educated group. With regard to dietary intakes according to Dietary Reference Intakes for Koreans, there were improvements in intakes levels of fiber, vitamin A, vitamin C, folate, calcium, iron and zinc. The index of nutrition quality, as indicated by nutrition adequacy ratio also improved in the educated group. Conclusions: These results showed that a nutrition education program providing education lessons and personalized school lunch by food exchange units according to daily needed energy showed positive changes in nutrition knowledge, dietary attitude and dietary intake of adolescent athletes. Nutrition education program providing personalized school lunch by Food Exchange Units may improve dietary behaviors and dietary intakes of adolescents.

In this study, four different oils containing either CLA, GLA, GLA+Carnitine or corn oil (control) were supplemented to finishing pigs (average 70.8 kg initial BW) diet for 28 d of feeding period. To evaluate the values of the dietary fatty acids, especially in view of sensory and nutritional characteristics of pork; pig performances, carcass characteristics, serum cholesterol, neutrophil phagocytosis, TBARS, electronic nose flavor and fatty acids profile of pork were measured. There were no differences in daily gain and nutrients digestion among treatments, but daily feed intake of CLA enriched diet was lower (P<0.05) than that of other diets. There were no differences in backfat thickness, dressing percentage and carcass grade among pigs fed diets supplemented with different oils. Serum total cholesterol showed a tendency to be lowered in pigs fed GLA enriched diet. TBARS values during storage of pork were higher in belly from pigs fed control diet whereas the values of belly from pigs fed GLA+Carnitine diet were lower than others. However, difference in TBARS was not remarkable in adipose tissue and 4 weeks extended storage regardless of pork parts. Proportion of saturated fatty acids such as C16:0 and C18:0 were higher (P<0.05) in pork loin and thin skirt from pigs fed CLA enriched diet compared to those from other diets. There were no differences in fatty acids profiles of belly and adipose tissue. CLA accumulation in pork was increased by the dietary CLA supplementation and this could be also confirmed by a slight de novo synthesis of CLA in pork from pigs fed CLA free diets. GLA was selectively accumulated to pork adipose tissue and loin from pigs fed GLA enriched diets. There was no accumulation of GLA when GLA was not supplemented, indicating no de novo synthesis of GLA. Phagocytic activity was the highest (p<0.05) in neutrophil of pigs fed GLA+Carnitine supplemented diet, then, followed by pigs fed GLA supplemented diet. There was no difference in phagocytosis between control and CLA treatment although the phagocytosis was numerically lowest in pig fed CLA enriched diet. There were distinct differences in electronic nose flavor pattern among treatments regardless of the parts. This study showed that dietary supplementation of functional fatty acids like CLA or GLA was able to result in characteristic differences in feed intake, TBARS, fatty acids profile and flavor of pork, serum cholesterol regulation and neutrophil phagocytosis.

In order to ensure good animal health and performance, it is essential to produce forages with high feeding value and good hygienic quality. However, huge amounts of forages consumed by ruminants are contaminated with mold prior to harvest or during storage as hay, straw or silage. These mold can grow in forages only when nutrients are available, correct temperature exist, oxygen is present, and unbound water is available. Fungal 'species can be divided into two groups: field fungi and storage fungi. Field fungi invade the forages while the crop is still in the field, require high moisture conditions, and are such as species of Fusarium, Alternaria, Clodosporium, Diplodia, Gibberrella and Helminthosporium. Storage fungi invade forages during storage and need less moisture than field fungi. These such as species of Aspergillus and Penicillium usually do not occur any problem before harvest. Mold growth can spoil the nutritional aspects of the forages and also results in secondary metabolites that are highly toxic to animal, humans and plants. Moldy feeds are less palatable and may reduce dry matter intake. This, in turn, leads to a reduction of nutrition intake, reducing weight gains or milk production. Performance losses of 5 to 10 percent are typical with moldy feeds. Mycotoxins are toxic substances produced by fungi (molds) growing on crops in the field or storages. While greater than 400 mycotoxins have been chemically identified, the biological or veterinary medical impact of only several mycotoxins is known. Mycotoxins have attracted considerable attention as potential causes for poor performance and health disorders in domestic livestock. They can be carcinogenic, hepatotoxic, hematotoxic, immunosuppressive, estrogenic, or mutagenic. So, feeding moldy forages has adverse effects on animal health and milk consumers. Also, this author reported that rice straw hay was contaminated mycotoxigenic fungi such as Penicillium roqueforti and Fusarium culmorum in Korea. Therefore, it is an urgent need to develop an improved post harvest storage method to reduce nutrient loss and mycotoxin contamination of forages, which will have a positive impact on human health.

A survey of 113 children, aged 4 to 6 years, of the San Cheon a day care center, located in the upland, over populated, poor area of Seoul City, was conducted from July 28 to September 6, 1982, to investigate the dietary and nutritional status, and prevalence of parasitic inpection. House size was 10.1 Pyung; number of households per house, 3.1; number of family member per household, 4.8; and number of family members living together per room, 3.7; on the average. Only 49% of households possess own houses and the others live in the rented houses. About 40% of mothers were engaged income-producing activities within or outside of the home. Mean values of height, weight, arm circumference, girth of chest, and girth of head ranged from 98.4 to 102.2% of KIST mean. However, 13% of the subjects were assessed as undernutrition for 'weight for height'. Mean value of hemoglobin was $12.9{\pm}2.9\;g/dl$ and mean hematocrit value was $35.2{\pm}5.5%$; 17.9% of the subjects were proven to be anemic according to the criteria of the WHO. The positive prevalence of parasitic inpection was 3.3%, significantly lower than that observed in any other area, probably because of community parasitic control project. Intakes of energy and nutrients except thiamin and ascorbic acid were far below RDAs. Carbohydrates for energy provided 71. 2 to 73.8% of total energy intake; protein accounted 11.3 to 12.2%; fat provided 14.5 to 16.6%. Energy intake was divided among breakfast, lunch, evening meal and snack, on the average, in a percentage of 22.0; 23.4; 24.4; 30.2. There was significant correlation between pattern of food consumption and nutrient intakes. The nutrient intakes and quality of foods were highly correlated to the maternal factors, especially mother's educational level. The study suggested that development of nutrition guides for mother and children would be needed to improve nutritional status of those young children.

The effects of unripe apple mask pack made from unripe apple extracts on the skin status of middle-aged women for 4 weeks were investigated. The subjects were divided into three groups: placebo mask pack as the control (PM, n = 8), apple mask pack (AM, n = 16), and apple mask pack + apple intake (AAM, n = 12). The study included a survey questionnaire, and evaluations of nutrients intakes and of skin status. Skin status was measured by Aramo-TS. After 4 weeks, facial moisture, elasticity, evenness, and wrinkle level were improved in AM and AAM. The facial moisture level (AM: $+3.13\;{\pm}\;2.73$, AAM: $+2.25\;{\pm}\;2.93$) and elasticity level (AM: $+5.81\;{\pm}\;8.27$, AAM: $+5.50\;{\pm}\;6.13$) of AM (p < 0.001) and AAM (p < 0.05) were increased. The facial evenness level (AM: $-5.25\;{\pm}\;8.13$, AAM: $-9.17\;{\pm}\;4.26$) and wrinkle level (AM: $-10.88\;{\pm}\;11.74$, AAM: $-17.83\;{\pm}\;12.22$) were significantly decreased. AAM was more effective in improving skin elasticity, evenness, and wrinkle. The skin status of PM was not changed. While the macronutrient intakes of all the subjects were not different before and after the study, the daily intakes of some vitamins (vitamins $B_6$, C, and E and folic acid) during the study were significantly increased in AAM. These findings suggested that regular use of apple mask pack was effective in improving overall skin status. Furthermore, the consumption of apples with mask pack application was much better in improving skin status.
