Two hundred and forty post-larvae (PL) of fresh water prawn, Macrobrachium rosenbergii were distributed in eight treatment groups with three replicates each. Eight experimental diets were prepared by using squilla (Orato squilla nepa), squid (Sepia pharonis) and clam (katelysia opima) alone or in different combination as source of animal protein and compared to a control diet containing fish meal. Total crude protein content for all dietary treatments was around 32%. Total protein content of fish meal was replaced by an equal amount of protein from different animal protein sources on isonitrogenous basis. Diets were fed at 5% of the body weight of post-larvae twice daily. The experiment was conducted for a period of 60 days. It was found that all the above three protein sources could be used by completely replacing fishmeal except clam meal at higher level of inclusion (26%). A combination of squid and squilla meal at 14% each in the diet increased the growth performance of PL significantly (p<0.05) in terms of Specific growth rate (SGR) % (5.17), FCR (2.12) and PER (1.51). Squilla meal can be used to the maximum level of 38% without any growth depression.

The diet composition of Arctoscopus japonicus was studied using 448 specimens collected in the coastal waters of East Sea, Korea. The size of the specimens ranged from 6.2-25.3 cm in total length (TL). A. japonicus were fed mainly on amphipods that constituted 76.1% in IRI. Euphausiids were the second largest prey component. The diets also include small quantities of crabs, copepods, mysids, cephalopods, monogeneans, and fishes. A. japonicus showed ontogenetic changes in feeding habits. Smaller individuals (6-10 cm, TL) fed mainly on amphipods. The proportion of amphipods decreased as body size increased, whereas the consumption of euphausiids gradually increased (10-14 cm, TL). As the body size more increased, the proportion of amphipods increased whereas euphausiids decreased (14-26 cm, TL).

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.

Growth and water quality in Japanese eel, Anguilla japonica ($6.0{\pm}0.9g$) fed extruded and paste type diets were compared for 8 weeks. Fish in the duplicate tanks were fed with one of three experimental diets: two different extruded pellet diets and one paste type diet. Six FRP tanks were used with stocking density of 3.6 kg per tank (3 m3). Restricted feeds (ca. 2% of body weight) were served twice daily. Weight gains were checked at the end of every two-week interval, and water qualities in terms of NH4-N and NO2-N were determined daily one hour after feeding in the morning. Water temperature, dissolved oxygen, and pH were constantly kept within the optimum range, while fifty percent of total water volume was changed daily. Eels fed the extruded pellet diets showed significantly better (P<0.05) growth performance than did eels fed the paste type diet. The amount of feed waste from the paste type diet was significantly greater than those from the extruded pellet diets (P<0.05). Ammonia (NH4-N) waste was significantly higher from the paste diet than from the extruded pellet diets (P<0.05). These results show that extruded pellet diets are better than the paste type diet for growth and water quality management in eel culture.

The effect of cecal ligation on the utilization of dietary [15N]urea in chickens fed 5 % protein diet plus urea were investigated. Nitrogen balance and utilization tended (P<0.01) to increase by cecal ligation. Total uric acid excretion was significantly decrease by (P<0.01) cecal ligation in chickens from origin of diet and urea (P<0.01). Excretion of ammonia was increased in chickens from origin of diet, where as it decreased in chickens an urea diet (P<0.01). Amount of urea nitrogen excretion from origin of urea was significantly decrease (P<0.01) by cecal ligation, but cecal ligated chicken fed 5% protein diet with urea showed 51.6% urea utilization. Result obtained in present study indicates that ceca is having beneficial role for urea utilization in chicken fed protein deficient diets, but ceca do not always positive role for nitrogen utilization.

PURPOSE. The purpose of this study was to investigate the effects of fasting and high-fat diet feeding on uncoupling protein 3 (UCP3) mRNA levels, uncoupling the respiratory chain and producing heat, of skeletal muscle in rat. METHODS. Fasting experiment: Forty Male Sprague-Dawley rats (5 wk) were divided into non-fasting groups (CON) and fasting groups (FG) for 0 day, 0.5 day (12 hr), 1 day, 2 day and 3 day. The rats of CON were sacrificed at 0 and 3 day. High-fat diet experiment: Forty Male Sprague-Dawley rats (5 wk) were divided into low-fat diet groups (LF) and high-fat diet group feeding for 0 day, 0.5 day (12 hr), 1 day, 2 day and 3 day. The rats of LF were sacrificed at 0 and 3 day. Analysis: Analysis of UCP3 mRNA expression was used by Real-time PCR. RESULTS. UCP3 mRNA levels of FG group were increased according to time course for 2 days- fasting but decreased at 3 day-fasting. UCP3 mRNA of HF were increased during HF diet feeding for 2 day, and peaked at 1 day-HF feeding, but decreased 2 day and 3 day-HF feeding CONCLUSION. Therefore, it may be rational that UCP3 is up-regulation when a large amount of fatty acids influx occurs in skeletal muscles as well as might have a role for fine adjustments of energy expenditure.

The purpose of this study was to investigate the compliance and need for diet therapy among diabetics and their caregivers. A total of 625 respondents participated in this survey. Appropriate management for long-term blood glucose control and difficult-to-manage cases appeared to be diet therapy, physical activity, medical treatment and folk remedies, in that order. The most important educational avenues for diet therapy were books, magazines and TV, Most respondents were educated in diet therapy within a year after diagnosis and had practiced diet therapy for over four years. The most common diet therapy Practices were food selection and Quantity control. Of the specific problems in practicing diet therapy, time and labor, taste, and meal planning appeared to be equally difficult factors. The prevailing diet therapy skills were controlling food amounts at breakfast and supper, and selecting food for lunch and refreshments. Respondents practicing both skills were about 20% of the participants; this shows the need to improve the current situation. The nutrients most frequently considered in diet therapy practice were simple sugars (sugar and sweet goods) , total fats and cholesterol. Since the perception of the role of dietary fiber among respondents was very low, nutrition education about the importance of dietary fiber and food sources of dietary fiber was needed. Diabetics seemed to be concerned about diabetic menus. Three difficult problems in planning diabetic menus were daily menu planning, patient's preferences, and the calculation of calories. As a means of nutrition counseling, they preferred interviews. The higher the educational status and the lower the age, the higher the preference was for internet or PC counseling. Therefore, it is necessary to develop nutrition educational programs so that diabetics can obtain practical knowledge of diet therapy. Furthermore, it is also necessary to develop additional means of informing diabetics about menu planning, while still considering Korean dietary behavior.

Purpose: The purpose of this study was to investigate the effects of 12-week brisk walking and brisk walking plus diet program on C-Reactive Protein(CRP) in middle-aged obese hypertriglycemic($triglyceride{\geq}150mg/d{\ell}$) Korean women. Method: The subjects were 16 obese ($BMI{\geq}25$) hypertriglycemic middle-aged women (7 for brisk walking group, 9 for brisk walking plus diet group) who participated in a health promotion program at one public health center. Initially the brisk walking intervention consisted of walking for 20 minutes/day at an intensity of 40 to 50% of heart rate reserve(HRR) for 3 days/week and progressed to 50 minutes/day, 60 to 70% of their HRR, and 6 days/week. The diet intervention consisted of 60 minutes of group education and 20 to 30 minutes of individual counseling with a nutritionist every week. Data were analyzed with SPSS PC program. Results: There was no significant reduction in CRP levels in both brisk walking (Z=-1.70, p=0.088) and brisk walking plus diet group(Z=-0.31, p=0.752). In brisk walking only group, CRP levels were increased after the intervention. Conclusion: Brisk walking could increase the level of CRP when it is in the course of progression and diet could decrease the acute phase inflammatory response.

The following experiment was designed to test the students' involvement in the interactive activities and objectives of the relevant chapters in the newly revised curriculum of 2007. The experiment was carried out with the purpose of understanding the level of participation of the Grade 9 students who have successfully completed the Grade 8 "Choice of Food and Diet" and "Table Manners and Dining Etiquette" courses with classified materials such as tables/diagrams/pictures, reading, and activity resources from Technology Home Economics textbooks. The chapters "Choice of Food and Diet" and "Food Preparation and Etiquette" generally emphasize the practical and experiential part of domestic life through using various activity resources; while the tables/diagrams/pictures and reading materials do not provide the students with first-hand experience, they support the students' learning by explaining the basic knowledge required for doing the activities and solving various problems. Within the main training courses, the objectives which the students achieved the highest marks were(in a descending order) "Table Manners and Dining Etiquette" (3.24), "Checking Nutrition Labels, Food Expiration Date, Country of Origin When Buying Food" (3.18), Additionally "Making Food" and "Planning a Healthy, Balanced Diet" hardly met the goals, the result of which shows clear relations to the well achieved objectives from the list of in-class activities that students directly participated in. Therefore, in order to increase the students' interest in the Food and Diet section of Technology Home Economics textbooks, it is recommended to encourage the students to actively engage in the class activities by developing various learning resources and teacher education/pedagogical materials, rather than following the conventional lecture-based teaching methods.
