This study examined the relationship between mothers' consciousness of diet and their infant feeding methods and weaning practices. Consciousness of diet analyzed from 17 questions concerning the attitudes and opinions of diet was classified into 6 categories using the factor analysis. These categories were the faithfulness of diet, the health-directed dietary practices, the application of health information, the application of information about food and nutrition, the sincerity to meal preparation, and dietary habits. The 400 mothers selected randomly from Wonju area were surveyed. The results obtained from the study were summarized as follows. Weaning was implemented earlier by the group with better education career and with the exact knowledge of weaning. Factors associated with infant feeding methods included some sociodemographic characteristics such as birth order, mothers' employment state and income level and mothers' effort toward faithfulness of diet. The use of health-foods and nutrient supplements were prefered by the groups used bottle-feeding method. The health condition of the infants was influenced by mother's will to carry out the health information rather than infant feeding methods and weaning foods used. Mothers who perceived the importance of diet for health and consumed more milk had healthier babies, and their dietary habits were more favorable. The subjects who self-recognized the meaning of weaning and who believed that earlier weaning was good for baby or delayed weaning was the cause of anemia and poor appetite, took advantage of the information about food and nutrition as well as prefered the health-directed dietary practices. Mothers who retried to feed the weaning food rejected by baby before, applied the dietary information to the real meal management more actively and had a more desirable dietary habits. In those cases the baby had improved health condition. Those who were interested in the meaning of weaning and the nutritious effect of weaning foods, revealed significantly higher tendency on the performance of cooking information and the more confidence to the health information from advertisement.

This study was to investigate the children's understanding level of nutritional knowledge and the degree of knowledge application into the actual living not only in the with-lunch school but also in the without lunch school. Having expected their obtaining of nutritional knowledge and practical applicating, we compared the with-lunch school children's understanding level of nutritional knowledge, dietary attitude, and completeness of diet life with those of without-lunch school children. In addition to this, we surveyed healthiness, Physical condition, and BMI (Body Mass Index) and compared these factors. The results are as follows. 1. Almost all of the children were standard in physical condition, however they recognized themselves fatty than normal. Mealtime consumption(p＜0.05), BMI(p＜0.05), and diet attitude points(p＜0.001) showed significant difference in the children who regarded the themselves healthy. 2. High correlation was observed between parent's physical shape and mealtime consumption (p＜0.05), quantity of eating food (p＜0.001), children's BMI(p＜0.001) and diet attitude(p＜0.05) respectively. 3. The points of itemised nutritional knowledge test was different in accordance with the children's year grade (p＜0.05), children's understanding level of health and physical condition(p＜0.05), parent's physical shape (p＜0.05), and mother's education level(p＜0.05) respectively. The points of nutritional knowledge test in both schools showed no difference except the item of vitamin.

Inclusion effect of various levels of jack mackerel meal (JMM) acting as feed attractants and/or stimulants in diets on the growth, feed consumption, feed utilization and whole body composition of rockfish was investigated. Three hundred juvenile rockfish were randomly allocated into 15 flow-through tanks. Five experimental diets supplemented with JMM at 0%, 1%, 3%, 5%, and 10% at the expense of anchovy meal were prepared and referred to as the JMM0, JMM1, JMM3, JMM5, and JMM10 diets, respectively. Weight gain, specific growth rate (SGR) and feed consumption of fish tended to improve with dietary levels of JMM. The greatest weight gain, SGR and feed consumption were observed in fish fed the JMM10 diet, followed by the JMM5, JMM3, JMM1, and JMM0 diets, in that order. Condition factor (CF) of fish tended to improve with dietary inclusion levels of JMM. Growth performance, feed consumption and CF of fish tended to improve with dietary inclusion levels of JMM ranging from 0% to 10%.

This study was carried out to investigate the effect of the difference of dietary compositions and environmental conditions on the growth and development of silkworm. The results obtained are as follows: 1. The more amount of soybean meal of diet was added, the more duration of the larval period was shortened. But Fifty percent increase of the amount of protein of diet leongthened the duration of larval period. 2. Fifth percent addition of the soybean meal to the diet does not influence the silkworm mortality, Whereas more than that gives rise to the adverse effect on the silkworm mortality. 3. The cocoon quality was significantly affected by the difference of dietary compesition. 4. In the environmental condition the duration of larval period was shortened in the high temperature and the dark condition. 5. The silkworm mortality was increased in the high temperature and the light condition. 6. The cocoon quality was significantly affected in the high temperature and the dark condition.

This study was conducted to determine the elements that are required and that need improvement in the contents of dietary life education and the educational environment by analyzing the importance-satisfaction of a dietary life education program for dietary life education trainees. The results of the rank test for the satisfactory elements of dietary life education were in the order of competence of instructors, educational contents, time of education, educational environment and affordability of tuition. The importance-satisfaction analysis of the contents and construction of the dietary life education program showed that "suitable contents for the theme of the class", "contents and construction of practice class", "diversity of practice menu" and "diversity of educational contents" had high importance and satisfaction scores and therefore, could be maintained at their current levels. Meanwhile, "adequacy of class time" and "contents and construction of theory class" showed low importance and satisfaction scores, requiring a little effort. Whereas, "time and construction of group practice", "structure of textbook for class" and "duration of course and number of classes" showed relatively low satisfaction compared to importance, requiring major efforts for improvement. Similarly, analysis of the lecture element from dietary life education showed that "professional lecture by instructors", "lectures suitable for themes" and "lecture applicable in real life" had relatively low satisfaction compared to importance, requiring major efforts for improvement. In addition, analysis of the educational environment from dietary life education showed that "adequacy of lecture room space", "cooking equipment", "diversity of cooking utensils" and "sanitary condition of cooking utensils" also require major efforts for improvement. Therefore, dietary life education should not be executed with a simple delivery of knowledge but with both theory and practice classes to increase its application in real life, and active and specific efforts are required to nurture professional instructors and establish educational strategies.

Background: Stress causes inflammation that impairs intestinal barrier function. Dietary spray-dried plasma (SDP) has recognized anti-inflammatory effects and improvement of gut barrier function. Therefore, the purpose of this study was to investigate the effects of dietary SDP on intestinal morphology of mated female mice under stress condition. Results: Villus height, width, and area of small intestines were low on gestation day (GD) 3 or 4 under stress conditions, and higher later (Time, P < 0.05). Crypt depth of colon was low on GD 4 and higher later (Time, P < 0.05). Meanwhile, the SDP treatments improved (P < 0.05) intestinal morphology, indicated by increased villus height, villus width, villus area, and ratio between villus height and crypt depth of small intestines and crypt depth of colon, and by decreased crypt depth of small intestines, compared with the control diet. The SDP treatments also increased (P < 0.05) the number of goblet cells in intestines compared with the control diet. There were no differences between different levels of SDP. Conclusion: Dietary SDP improves intestinal morphology of mated female mice under stress condition.

Purpose: This study aimed to clarify the characteristics of musculoskeletal problems in elderly Korean women and their actual and current use of dietary supplements by conducting a descriptive survey. Methods: The 1-month study began on April 3, 2012. A total of 150 elderly women from City D responded to the survey questionnaire used in this study. Results: Among the respondents, 55.3% used dietary supplements, although they had not consulted a physician for a definitive diagnosis of their condition but reported a self-perceived musculoskeletal problem instead. In addition, they engaged in healthy behaviors such as exercising and dietary supplement intake, without receiving any medical treatment. Compared with the nonusers, the dietary supplement users self-perceived a relatively more serious musculoskeletal problem (t =4.566, p<.001). Among the most commonly used supplements, multivitamins ranked first, followed by glucosamine and omega-3. Conclusion: Nurses should thoroughly monitor and maintain a positive attitude toward their patients' use of dietary supplements in order to appropriately educate them about the proper use of supplements.
