It is important to supply adequate nutrition to critically ill patients, whose gastrointestinal system is properly functioning, through the enteral tube feeding if oral intake is impossible. In this study we investigated the changes in nutritional status with enteral tube feeding according to the volume required. We investigated the volume ordered according to the patient's requirements, volume infused according to the volume ordered in 41 enteral tube feeding patients in intensive care unit from Jannuary to July, 2000. Body weight, serum albumin level, and total lymphocyte count were evaluated to assess nutritional status. The mean fasting period was 5 days before the enteral feeding and patients whose fasting period over 3 days were 51%. The mean enteral tube feeding period was 29 days and method of feeding was nasogastric, bolus feeding 6 times per day. The volume ordered was 69.7% of the patients' recommended calorie and volume infused was 86.6% of their volume prescribed. Accordingly, the volume infused was estimated 61.7% of their volume required. Only 44.6% of their reqiured volume was infused within 3 days after enteral tube feeding was started. It took 16 days in average to meet the patients' recommended calorie; 56% of subjects still did not fully met their requirements by the end point. Among the impeding factors in supplying enteral tube feeding, factors related to the number of feeding were high residual volume in stomach, vomiting, gastrointestinal bleeding, abdominal distension and surgery. Factors related to the acctual infused volume were diarrhea, gastrointestinal bleeding, abdominal distension, airway management and tube reinsertion. Significant correlations were shown between the volume infused and changes in both the patients' weight and serum albumin level. Deviding the subjects into two groups by their infused volume, less than 70% and more than that, we compared the two to come up with a significant difference in their serum albumin level, -0.23 vs 0.21, and their body weight, -4.52 vs 0.12. In enteral tube feeding, the volume delivered in sufficient to the pateints' energy requirement can affect their nutriitional status in critically ill patient; adequate nutritional management plan is essential. It is necessary to make every effort to educate clinical staff and to set up a unified management program to prescribe adequate ammount of energy for the patient's nutritional requirement.

This study was carried out to investigate the feeding practices, growth status and correlation with maternal perceptions of breast feeding and lactation with infuts' feeding methods in the Pocheon area. The subjects were 103 infants ranging from 3 to 21 postpartum months and their mothers. The results obtained were as follows : In this survey, 36.9% of the infants were breast-feeding, while 53.4% of them were bottle-feeding, and 9.7% of them were mixed-feeding. The reason for bottle-feeding was due mainly to the lack of breast-milk secretion. Z-scores of weight-f3r-age and height-for-age were similar to Korean standards, but malnutrition and overnutrition were also noticed by kaup index and WLI. The average maternal perceptions of breast-feeding and lactation was 3.7 out of 10 possible points, the breast-feeding group scored 4.7, and formula-feeding and mixed-feeding group scored 3.0. That of BF group was higher than FF+MF groups and was positively correlated with growth status. Therefore to ensure proper growth of infants and to promote breast-feeding, efforts should be given to community nutritional services including nutrition education for the importance of colostrum and breast-milk, practical breast-feeding methods, and nutritional management during pregnancy. Also nutrition education for mothers will be continued to 1-3 postpartum months to promote successful breast-feeding.

The aim of this study was to investigate the effects of three herb supplementations on blood metabolites, hormones, antioxidant activity, immunoglobulin (Ig) G concentration, and ruminal fermentation in steers. Four Holstein steers in a $4{\times}4$ Latin square design received four herb treatments. The treatments consisted of the steers' regular diets with addition of: 1) nothing (control), 2) peppermint, 3) clove, and 4) lemongrass at 5% of the diet (DM basis). Clove supplementation increased the plasma concentration of cholesterol by about 10% (from 79 to 87 mg/dl). Peppermint and lemongrass feeding resulted in an increase in the concentrations of plasma urea nitrogen (from 5.9 to 6.9 and 6.4 mg/dl, respectively). The three herb treatments had no effect on other metabolites and hormones. Steers receiving clove supplementation showed a higher plasma antioxidant activity. The three herb treatments caused lower concentrations of IgG in the blood. Peppermint and lemongrass feedings increased, and clove feeding decreased ruminal concentrations of ammonia. There were no significant differences in VFA concentrations among herbal treatments, except for the decrease in propionate concentration in steers receiving clove treatment. This study suggested that clove feeding changed cholesterol metabolism and increased antioxidant activity in plasma, and feeding of three herbs affected immunity system and ruminal fermentation in steers.

This study was attempted to investigate the current status of industry food service management in Chonbuk province. The survey for the analysis was conducted through the questionaires to dietitian. The following results are to be noted. 1. Only one dietitian was employed regardless of feeding numbers and feeding times, and the average number of cooks comes to 5∼6 persons. Among 51 food service places for the study, 84.3% provided more than two meals a day. Feeding number were 200∼1000 people per one meal (64.7%) and feeding cost amounts to 700∼1000 won per meal per one person. 2. The food preferences and budget were primary considerations in menu planning. The type of menus was a non-selective menu with a seven-day cycle (83.7%). Most of dietitian (94.1%) had control of food purchasing, receiving and checking procedure and prefered placing orders by phone (94.5%) through the purveyors (86.4%). 3. In many food service places (70.5%), the mass food preparation was controlled of cooking method and standardized recipes were not undertaken by management Also, the food quality control such as flavor, texture, appearance and temperature was not fully established in food service system. 4. They used the method of manual dish washing operations (88%) and about 71.4% of them are dependent on boiling method of ultrabiolet light for disinfection of kitchen utensils. 5. The performance rates of dietitian management responsibility showed as nutritional management 100%, working management 72.4%, sanitary management 85.6%, personnel management 64.5% and nutrition education 40.7%, but they did not perform the objective and systematic their own responsibility as specialized dietitian because only few dietitian used basic check list and management tools. In addition, dietitian (21.6%) worked beyond their field. In the result, only 54.9% dietitian have satisfied their own occupation and most of them emphasized on practical working in educational curriculums.

This study was performed to investigate the nutritional status of neurosurgical tube-fed patients. The objective of this study was to improve the nutrition management of tube-fed patients. The current practices of tube feeding and enteral nutrition formula as for 95 patients in the hospital were examined by reviewing patients charts, and interviewing patients, nurses and their family members. The results are summarized as follows ; 57.9% of patients that received the formula showed a decrease in mental status. Among the subjects, 55.7% had nervous system diseases due to old age. Most of the tube-fed patients were hospitalized in the emergency room and while hospitalized, the status of their respiratory organ was abnormal. The method of tube-feeding was by Bolus injection and the type of the tube was a 16Fr size silicone tube. The amount of the injection per day while tube-feeding was on average 1424kcal for men and 1322kcal for women and the calories per day ranged from 1000-1500kcal(50.5%). The injection volume averaged 332.7ml and 45% of patients received more than 300ml per injection. The tube feeding intake rate was 127.9ml/min with 50% of subjects in the range of 50-100ml/min and 10% at 20ml/min. The longer the hospitalization, the older age, coma status, and the higher tube feeding rate, the more decreased were the biochemical parameters.

The purpose of this study was to investigate a plan of middle/high school foodservice systems which could properly provide nutrition for juveniles' health. Questionnaires were developed and distributed to: 245 middle schools with 271 parents, 328 students, 180 teachers, and 345 administrators; 163 high-schools with 223 parents, 466 students, 179 teachers, and 163 administrators in Seoul and Kyunggi province. The results of this study were as followed. For the desirable feeding type as in-school meal plan, 62.2% responded to the current elementary school feeing type:10.3% responded to a lunch-box prepared at home; and 38.0% responded to free dining out type. For a feeding operation type, school administrators, teachers and parents favored the current school feeding systems in elementary schools with proportion of 68.2%, 47.7%, and 87.6% as respectively. Also, 20.3% of school administrators, 22.6% of teachers, and 6.9% of parents preferred contract management. A total of 27.6% of teachers, 9.2% of school administrators, and 3.7% of parents responded to a lunch-box prepared at home. There was a significant difference between the responses for establishing the main body of financial burden to solve the problem of financial burden which could be the most obstacle to bring middle/high school feeding system into operation. For the management of school feeding systems when brought into operation, 88.7% out of 470 responded schools and 89.9% out of 227 responded teachers reported that an expert should manage school feeding systems. For futuristic direction, an effective joint cooking type between schools which may be the way to solve the difficulties in securing the appropriate space and to decrease the financial burden, the problem of transportation for delivering feeding products, low quality of feeding, and sanitation can occur. Therefore, the distance between schools which operate a joint cooking system will affect as a major factor. Furthermore, concrete examination of plans for introduction of various types of school feeding and institutional devices for management system and supervision of operation should become a condition precedent.

Background: Liquid feeding system has been introduced to domestic swine farms, but negative cognition about liquid feeding system has been remained for feed waste decay related with poor management and microbial contamination. For these reasons, this study was conducted to evaluate the effects of feeding method in lactating sows. Methods: A total of 30 mixed-parity (average 4.13) lactating sows (Yorkshire ${\times}$ Landrace) with an initial BW of $218.8{\pm}19.5kg$ was used in a 3 week trial. Sows were allotted to 1 of 2 treatments in a completely randomized design by their body weight, backfat thickness, parity and alive litter weight. One of treatments was dry feeding and the other was liquid feeding (water to feed ratio, 1:1). Experimental diets contained 3265 kcal ME/kg, 12.6 % CP, 5.76 % EE, 1.09 % total lysine, 0.25 % total methionine, as fed basis. Results: Dry feeding treatment had high body weight loss rather than liquid feeding treatment (P = 0.04). Dry feeding treatment had tendency to increase litter weight at 21d of lactation (P = 0.06) and litter weight gain (P = 0.04) during lactation period (0-3 week). Sows fed dry feeding method made milk containing high content of casein and total solid rather than sows fed liquid feeding method (P = 0.04). In addition, dry feeding treatment had tendency to higher content of milk fat, protein and solid not fat on 21d of lactation (P = 0.07). Sows fed dry feeding type also showed higher milk energy content in milk of 21d lactation (P = 0.05). Furthermore, liquid feeding treatment showed high occurrence in feed waste during lactation period (P <0.01). Conclusion: Dry feeding method was more suitable feeding method to lactating sows under high temperature environment like lactating barn.

Feeding preference of cigarette beetle, Lasioderma sewicorne F., on cured tobacco leaves was investigated to obtain basic information on ecological management of the insect pest in tobacco storage warehouses. About 3, 000-4, 000 adults of the insect were released in a warehouse in which groud tobacco leaves were placed on the bottom and at 3m above the floor level, and numbers of insects attracted were examined. There was no significant difference on feeding preference between the two tobacco varieties, flue-cured(NC82) and air-cured(Br3l) tobacco leaves. However, significant differences were noted in feeding preference between thick and thin leaves and among different quality grades within a tobacco variety. Feeding preferences of cigarette beetle between flue- and air- cured tobacco varieties showed significant differences on the lower position, though there were no differences on the 3m upper position. On the 3m upper position, feeding preferences were different between thick and thin leaves of tobacco varieties, and variety X thickness and variety X thickness equality grades showed statistically significant differences. Significantly higher feeding preference by cigarette beetle adults was observed for the food placed on the 3m upper than on the lower position. There were negative correlations between quality grades of cured tobacco leaves and feeding preference on the lower position, and the regression equation was Y(feeding preference)=4.050-0.683 X (degree).

The feeding habits of the Japanese jack mackerel Trachurus japonicus were studied in the Southern Sea of the Republic of Korea. To assess the effects of season, sampling was conducted in February (winter), May (spring), and August (summer), 2020. The total length of each fish was measured in 1 cm intervals. Diet composition showed the highest species diversity during winter. Diet composition changed from copepods to euphausiids as the total length of jack mackerel increased, except during winter. The most important seasonal prey were copepods in winter and summer and euphausiids in spring. Species diversity of the zooplankton community structure was highest in winter. Among the zooplankton communities, copepods were dominant in all seasons. Species with a high electivity index in all seasons were relatively large zooplankton of ≥2 mm. Jack mackerel had ontogenetic diet change, exhibited diet selectivity depending on size, and its feeding habits were affected by the zooplankton community structure.
