This study examined the lifestyle factors, dietary attitudes, food habits, and dietary nutrition intake of college students before and after nutrition education. A total of 44 college students were recruited and a questionnaire survey was conducted. Dietary nutrient consumption was obtained from the one day 24-hr recall. Scores on 'Concerns about health (p<0.05)', 'Regular exercise (p<0.01)', and number of steps (p<0.001) were significantly higher after-training. The dietary attitude (31.3 vs. 33.7, p<0.01) and food habits (53.5 vs. 59.7, p<0.01) were significantly higher after-training. The scores on 'Eating a lot of food that I want to eat is more important than nutrition (p<0.01)', 'I am interested in information on nutrition and health (p<0.01)', 'Have three meals a day (p<0.01)', 'Have breakfast regularly (p<0.01)', 'Drink milk every day (p<0.001)', 'Have fruits every day (p<0.05)', and 'Apply nutrition knowledge to daily life (p<0.001)' were significantly higher after-training. Among the nutrients intakes, the protein (p<0.05), vitamin C (p<0.01), and calcium (p<0.001) were significantly higher after-training. Nutrition education improved the lifestyle factors, dietary attitudes, food habits, and dietary nutrition intakes.

The influence of dietary supplementation with a yeast culture on growth performance, fecal score and nutrient digestibility was evaluated in weaned pigs in a 6-week feeding trial. A total of 50 weaning pigs with an initial average body weight (BW) of $7.46{\pm}1.60kg$ were randomly allotted into 1 of 2 dietary treatments according to the initial BW. There were 5 replicate pens in each treatment with 5 pigs per pen. The dietary treatments were as follows: 1) control, basal diet (CON) and 2) 0.10% yeast culture, basal diet supplemented with 0.1% yeast culture (YC). The average daily feed intake was significantly improved with the dietary supplementation of the yeast culture compared with the control during phases 1 and 3. Overall (0 to 6 weeks), dietary supplementation with the 0.1% yeast culture had a significant effect on the feed conversion ratio (FCR). There was no significant difference in the fecal score between the CON and YC dietary treatments. In addition, no difference in the apparent total tract digestibility was observed between the CON and YC dietary treatments. Collectively, the results of this study indicate that dietary supplementation of 0.1% yeast only improved the feed intake of weaning pigs; however, yeast culture supplementation did not affect the average daily gain, feed efficiency, total tract digestibility of dry matter, and nitrogen and energy levels as well as the fecal scores.

The aim of this investigation was to assess the difference of health behaviors, dietary patterns and nutrient intakes between smokers and nonsmoker from 435 free living elderly in Kyunggi province. The study subjects were interviewed to collect general characteristics and health behaviors such as smoking, exercise, alcohol consumption, and food habits by questionnaires and nutrient intakes by a 24-hour recall, and weight, height, waist, hip, and blood pressure were measured. The percentages of smoker were 52.3% in males and 12.1% in females. Current smokers were fond of alcohol, salty or hot food, tended to have meals irregularly and insufficient sleep, and were inactive lifestyle compared to nonsmokers. Smokers consumed fewer servings of vegetables, fruits, and beans and their products. Women who smoked consumed less energy, carbohydrates, and vitamin E than nonsmokers, and their nutrient adequacy ratio of protein, iron, phosphate, niacin, vitamin B1, and vitamin C were significantly lower than nonsmokers. There were no differences of nutrient intakes and nutrient adequacy ratio between smokers and nonsmokers in male subjects. In conclusion, elderly smokers tended to have less healthy life style, food habit, and dietary nutrient intakes which may influence the deleterious effects of smoke components on cancer and coronary heart disease risk, thus health education program should include nutrition education as well as smoking cessation.

The objective of this study was to assess the effects of dietary carbohydrases on growth performance, nutrient digestibility and blood characteristics in finishing pigs. A total of 90 pigs [(Landrace ${\times}$ Yorkshire) ${\times}$ Duroc] (initial BW = $56.15{\pm}1.26kg$) were used for a 35 d feeding trial. The dietary treatments included: 1) CON (control diet), 2) MIX (CON + mixture with ${\alpha}$-galactosidase and ${\beta}$-mannanase 0.05%) and 3) MAN (CON + ${\beta}$-mannanase 0.05%). There were six replications per treatment with five pigs per pen. The average daily gain (ADG) in MIX was higher than in CON (p<0.05). No significant differences were noted in the average daily feed intake (ADFI) and feed efficiency (G:F) among dietary treatments (p>0.05). Apparent total tract digestibility (ATTD) of dry matter (DM) and energy (E) in MIX increased (p<0.05) relative to CON and MAN. The ATTD of nitrogen (N) in MIX was higher (p<0.05) than in CON. No differences in red blood cells (RBC), white blood cells (WBC), lymphocytes and IgG concentrations were observed among dietary treatments (p>0.05). In conclusion, the addition of the mixture of carbohydrases (${\alpha}$-galactosidase and ${\beta}$-mannanase 0.05%) increased ADG and nutrient digestibility in finishing pigs.

This study was performed to investigate the degree of different stresses and to search the influence of food habit and nutrient intakes at stress situation in university students and secondary school teachers. The data was collected by questionnaire method and searched nutrient intakes by 24 hours recall. The subjects were 282 students and 152 high school teacher in Kyunggi do. Physical status was no difference with two groups. Energy intake of teachers was lower than that of students, but the intakes of vitamin A and C were high in teachers' group. The university students had more stress situation than teachers in almost kind of stresses except overload stress. Self-diagnosed dietary habits were better in the group of teacher. Especially smoke and alcohol drink behavior were correlated with nutrient intakes in male teachers and students. The quantity of nutrient of nutrient intakes was correlated with different kind of stress. The stress of life event was correlated with the intakes of carbohydrate, minerals, thiamin and riboflavin, and the deprivation was with iron and vitamin A in teachers' group. The intake of almost nutrients was correlated with the stress of noise in students' group. By the analysis of stepwise multiple regression, although the $R^2$ values were very low, vitamin C intake was influenced in the factor at the stress of life events($R^2$=0.025), self-efface($R^2$=0.030) and noise($R^2$=0.020), thiamin was at food induced stress ($R^2$=0.021) and vitamin A was at the stress of type A behavior($R^2$=0.022) and anxiety response($R^2$=0.014). Therefore, we could concluded that different kind of stresses were influenced in dietary behavior and nutrient intakes. More research would be needed at the aspects of health promotion in the stressful situation of modern society.

The purpose of this study was to compare the dietary habit and nutrient intakes of Korean farmers according to their different family patterns and farming types. Food and nutrient intakes were obtained by food frequency method. The subjects(male 35%, female 65% : mean age, $48{\pm}11 years)$ were compared 46% of nuclear family, 59% of 3-4 person of family size ; 50% of middle-scale farming ; 54% of rice farming. Sixteen percent were over 60 years old group. In aspects of dietary habit, farmers of medium size farming and 10-20 years of farming experience frequently skipped meals. But their appetite was better than small farm famers. Dinner irregularity was more frequent in their group of 3-4 person families. The numbers of food intake were significantly different according to family pattern. Nuclear family groups consumed more kinds of foods. The mean energy intake was 2000Kcal/day, with PFC ratio of 19 : 16 : 65. The energy and nutrient intakes showed the same tendency as the food variety. Intakes of calcium and iron were lower than the Korean RDA. Families with over 5 people consumed higher amounts of protein and minerals. Intakes of thiamin, niacin, and vitamin E were better in large families and large-scale farming groups. As compared with the PMS ratio, the level of monounsaturated fatty acids as higher than saturated FA. The lipid intake was also better in large families and large-scale farming. The results suggest that dietary habit and nutrient intakes were different by family pattern and farming types.

A deep understanding of the dietary patterns and nutrient intake is important for assessment of possilbe nutritional risk and for establishing nutrition improvement strategies. This study was conducted toexamine the dietary characteristics of a nutritionally poor elderly group compared to the middle-and highly-nourished group. Elderly participant was recruited from local elderly centers in Suwon city in 1998. Trained dietitians interviewed 119 elderly(35 males, 84 females) aged 60 years and over for collecting dietary data(24-hour recall) and related variables. Male and female subjects were grouped into high, middle, and low according to the mean nutrient adequancy ratio(MAR) tertiles. An analysisof the percentage of RDA(Recommended Daily Allowances of Korea) for each of the 10 nutrients showed that the male low-MAR group consumed below the RDA in all kinds of nutrients, and the female low-MAR group consumed nutrients below the RDA except vitamin C. An evaluation of nutrient density by Index of Nutritonal Quality(INQ) also showed a similar tendency. Thus, the INQ level of the male low-MAR group was significantly lower than the middle-or high-MAR group, especially in protein, vitamin A, thiamin, riboflavin, and phosphorus(p<0.05). Moreover, INQ level of female low-MAR group was significantly lower than that of the high group(p<0.05) in all nutrients. The female low-MAR group's daily food intake were also lower than those of the high-MARgroup in gains, fish, fruits, oil and beverages. The energy distribution from carbohydrates, fats and proteins showed that the male low-MAR group had significantly higher carbohydrate and lower fat proportions compared to each gender high-MAR group, respectively. The male and female low-MAR group had low scores about eating all side dishes. These findings indicate that a moderate increase of the meat/egg/fishes intake was needed by the male low-MAR group for improving nutrition adequacy, and an overall increase of the food quantity and quality was desired for the female low-MAR group. These data could be used for planning a community elderly nutrition program and establishing strategies for tailored guidelines for the individuals.

Objectives: This study was undertaken to compare dietary life of the elderly living alone and in a family, and to compare differences based on gender, for the 2013-2016 Korea National Health and Nutrition Examination Survey (KNHANES). Methods: The subjects included 2,612 elderly people aged over 65 years who participated in the health survey, health examination and nutrition survey. Subjects on a diet therapy were excluded. This study analyzed the general characteristics, dietary habits, daily energy and nutrient intakes, CPF ratio, estimated average requirement (EAR), nutrient adequacy ratio (NAR) and mean adequacy ratio (MAR), index of nutrient quality (INQ), and food consumption of the elderly living alone and in a family. We also compared the differences based on gender. Results: Daily intake of food, water, dietary fiber, potassium, retinol, and riboflavin were low in the male elderly subjects living alone. The elderly living with family revealed higher NAR and MAR as compared to the elderly living alone. Although all MAR values were <1, the elderly living alone had lower values. Considering the intake of food, the consumption of seaweed, fish and shellfish, and oils (animal) was higher in elderly men living with families, whereas women living with families consumed more vegetables, fruits, seaweeds and seafood, as compared to their counterparts living alone. Furthermore, analyzing the foods consumed by the elderly people living alone, female subjects consumed more seaweed, milk and animal oil as compared to male subjects. Conclusions: The results of this study indicate that the elderly living alone have poor nutrient intake as compared to the elderly living with families. Based on this research data, we recommend that it is necessary to improve the health and nutritional status of the elderly living alone.

Effects of dietary cellulose and protein levels on nutrient utilization in chickens were investigated. Four experimental diets containing 5% (low cellulose) or 20% (high cellulose) cellulose in combination with 10% (low protein) or 20% (high protein) protein of 70 g/day were alternatively forced-fed to eight colostomized White Leghorn cockerels once a day to make $4{\times}4$ Latin-square design. The digestibilities of DM and energy decreased with the increase in cellulose level, but not affected by dietary protein level. Ether extract digestibility was higher in the high cellulose diets than in the low cellulose protein level. Ether extract digestibility was higher in the high cellulose diets than in the low cellulose diets. The digestibility of nitrogen free extract had the same trend with the digestibility of DM and energy. The digestibility of acid detergent fiber was not so much different among the diets, but the NDF digestibility was lower in the high cellulose diets than in the low cellulose diets, due to the low hemicellulose digestibility. The true digestibility of protein was influenced by both of the dietary protein and cellulose levels, and their interaction was found. The dietary protein level affected the biological value of protein but the dietary cellulose level did not, and consequently the biological value of protein in the low protein diets was lower than in the high protein diets.

The purpose of this study was to investigate the dietary habits and nutrient intakes of the elderly living in Songnam area. Responses from 318(153 men, 165 women) elderly individuals aged from 58 to 92 were analyzed. The results of this study are as follows. Regular dietary habit scores of the elderly women were worse than those of the men. Balanced dietary habit scores turned out to be the lowest among the various measured indices. The dietary assessment data showed that the energy intakes of males and females were 86.8% and 83.1% of the RDAs, respectively. The nutrients taken less than RDA on the daily basis were protein, calcium, iron, vitamin A and vitamin B$_2$. Nutrient intakes were gradually decreased as the age increased. Energy intakes of males and females from carbohydrate were 70% and 73% respectively. Vitamin A, vitamin B$_2$, and calcium were the most deficient nutrients on the basis of the intake percentage of RDA. Therefore, to improve nutritional status of the elderly, it is recommended that intakes of vitamin A, B$_2$ and calcium-rich food should be increased. Also suitable dietary guidelines and educational programs seem to be necessary for promoting health conditions of elderly people in Songnam area.
