This study was carried out to determine the effects of sodium alginate and cellulose on the cholesterol metabolism in cholesterol-fed rats. Thirty male Sprague-Dawley rats were randomly assigned to three dietary treatments. Rats were fed, ad libitum, diets containing 10% dietary fibers as sodium alginate, cellulose or fiber-free with 1% cholesterol for 4 weeks. The results obtained were as follows: the feeding of sodium alginate with 1% cholesterol induced a significant decrease in plasma cholesterol and TG. The feeding of sodium alginate significantly decreased hepatic total lipids and TG levels, whereas the feeding of sodium alginate significantly increased hepatic HMG-CoA reductase activity. The feeding of sodium alginate and cellulose significantly increased fecal cholesterol and bile acid excretion. The excretion of TG in sodium alginate group, however, was two-fold and four-fold increased compared to cellulose and fiber-free group, respectively. As a result of this study, the ingestion of sodium alginate decreased plasma cholesterol and TG concentrations and liver TG concentration. This may be explained by the facts that fecal cholesterol, bile acid and TG level were increased significantly in sodium alginate group. The increased hepatic HMG-CoA reductase activity by sodium alginate feeding appears to be corresponded to whole-body cholesterol homeostasis.

Mother and infant relationship has a great influence on child's developments. In this study, nursing intervention to increase maternal sensitivity to the infant's cues was applied to 25 primiparas (Experimental Group). Mother and infant interacations of these primiparas were compared with those of 25 primiparas (Control Group) who did not receive the nursing intervention. Fifty primiparas and infants were recruited from a university hospital, a general hospital, and an OBGY clinic located in Taegu city. Mother and infant interactions were assessed at 6 weeks after birth using videotapes. Feeding situations were videotaped and two trained observers analyzed the tapes. Data were collected from March 23rd to July 27th of 1998. Mother and infant interactions during feeding were assessed by the response rating scale which was modified by the author based on NCAST feeding scale (Barnard, 1978a) and AMIS scale (Price, 1983). The validity of the modified rating scale was verified by faculty members and researchers who previously had research experience in the area. Cronbach's Alpha of the modified scale for this study was .90. The data was analyzed by SAS program, using wilcoxon rank sums test, chi square test, Fisher's exact test, and ANOVA. Findings were as follows: 1. Mothers in the experimental group were more likely to have higher scores in mother and infant interactions during feeding than mothers in the control group. 2. Mothers in the experimental group showed better sensitivity to infant's signals or cues, provided growth fostering, and had higher responsibility to the infant's distress than mothers in the control group. 3. Infants in the experimental group showed higher clarity of cues and responsibility to the mother's behaviors than infants in the control group. 4. Mothers and infants in the experimental group showed higher synchronic responses than mothers and infants in the control group. In conclusion, this study has shown that the applied nursing intervention promoted mother and infant interaction among primiparas. Therefore, this study suggests that the nursing interventions to increase maternal sensitivity to the infant's cues should be broadly applied to primiparas, which can be beneficial to the social, affective, and cognitive developments of their children.

The main objectives of the present study were to understand the knowledge and practice of breastfeeding mothers about the feeding and supplementary food and to analyze the factors related to it. The data for the present study collected from July 9 to July 31, 1984 for 302 mothers in Seoul. 1. The Knowledge of Breastfeeding Mothers about the Fee4ing and Supplementary Food (1) In the knowledge of mothers on the appropriate feeding pattern before 6 month, 69.3% of total women believed that breast-fed babies are healthier. There was a singificant difference in the type of feeding in order to education level, socio-economic state, and. mass-media exposure. (2) In the knowledge of mothers on an appropriate duration of lactation, the mean duration of breastfeeding is 8. 1 month. The duration of breastfeeding gradually decreases in order of education level, socio-economic state, mass-media exposure, and employment status. (3) In the knowledge of mothers on an appropriate time of introduction of supplementary food, the mean time of introduction of supplementary food is 4. 7 month. It is gradually decrease in order of education level, socioeconomic state, mass-media exposure, and employment state. 2. The Practice of Breastfeeding Mothers about the Feeding and Supplementary Food (1) The practice of mothers on infant-feeding before 6 month and that education level, socio-economic state and mass media exposure are the higher, the rate of breast feeding is the less. (2) The mean duration of breastfeeding is 9 month. It is 1 month longer the knowledge of mothers on an appropriate feeding pattern before 6 month. (3) The time of introduction of supplementary food is average 4.75 month. It is similar to the knowledge of mothers on an appropriate time about introduction of supplementary food. The result of this study indicate that the knowledge and practice of breast feeding is maintained comparatively high in low educated group, whereas it is noticeably decreasing among the high educated group. High educated group believed that the short duration of breastfeeding better than long, and they practiced breastfeeding so short period. And high educated group also thought early introduction of supplementary food is good for the babies health. Consequently, in this study, for the most part, elite group is found to have rather wrong opinions and practice about infant nutrition. Therefore the accurate information of infant nutrition is must be encouraged to mothers.

본 연구는 엘크 사슴의 사육방식에 따른 사료섭취량, 체중 변화 및 녹용생산성에 미치는 영향을 확인하기 위하여 실시하였다. 엘크 사슴 12두를 공시하여 사사사육과 방목사육 형태로 사육하였으며, 처리구 간에 섭취량은 유사하게 나타났다. 일당증체량과 녹용생산성의 경우 방목사육 형태가 높게 나타났는데, 일당증체량은 방목사육 시 약 39% 높은 경향을 보였는데 이는 발육 개선효과가 있을 것으로 생각된다. 녹용 생산성 역시 방목사육 시에 약 19% 높은 경향을 보였다. 그러나 녹용 생산성의 경우 개체 간 편차가 심하여 통계적 유의성은 인정되지 않았다. 본 시험에서 방목사육 시에 일당증체량과 녹용 생산성이 높게 나타난 것은 방목에 따른 조사료원의 영양적 성분이 높기 때문으로 생각된다. 이러한 결과는 사슴 방목의 효과에 대한 기초자료로서 충분이 활용될 수 있을 것이며, 앞으로 계절과 방목지의 초종에 따른 녹용의 생산성과 안정성에 대한 추가적인 연구가 수행되어야 할 것으로 생각된다.

The prevalence of iron deficiency in later infancy and the toddler years(25% to 40% at 1 year of age) has not decreased remarkably , except in Western countries. The purpose of this study was to 1) determine the relationship between current feeding practices and iron status, and 2) assess compliance to infant feeding instructions. Two groupsof infants were examined. The first group of 302 infants aged 6 to 24months was seen at a well baby clinic while the second group of 135 infants of the same age group was assessed by venipuncture. Cutoff values for laboratory tests were as follows ; hemoglobin<11g/dL, mean corpuscular volume (MCV) <72fl ; red cell distribution width(RDW)>15% ; serum ferritin level<10ng/ml ; and transferrin saturation (serum iron(TIBC)<10%. The diagnosis of iron deficiency anemia (IDA) was made when a low hemoglobin level was associated with either low ferritin orlow transferrin saturation . Of the 302 children brought to the well baby clinic , 12.3%(n=37) were found to have anemia (hemoglobin<11.0/dL). In terms of children grouped according to feeding practices, it was found that children with anemial comprised 32.0% (24/75) of the prolonged breast-fed group (Group A), significantly more than the 4.0%(7/176) of the artificial milk feeding group(Group B). and 3.9%(2/51) of the switched from breast milk to iron -fortified weaning foods group(Group C).Among the 107 children with IDA , iron deficiency in 105 children(98.1%) was suggested by their dietary histories ; exclusive or prolonged breast-feeding for more than 6 months without iron fortification in 98 infants ; cow's milk consumption> 500ml/day without iron fortification during infancy(n=12), or >800ml without iron-fortified foods after infancy(n=15) ; and the use of unfortified forumula or unbalanced diets, mainly limited to rice gruel. Despite the relatively high (79.6%) motivation on the part of the infants mothers and supervison by professional personnel, the poor results in the infants receiving iron fortified foods were due to poor compliance(85.75). Among the mothers of 98 IDA patients who were contacted by telephone , it was revealed that 29% did not give the oral iron preparation for more than 2 months. Furthermore, negligence or disregard by the parents occurred in 14% of the case , discontinuance of the oral iron preparation by the parents due to side effects occurred in 6%, and the children's refusal or poor oral intake and no further trial occurred in 6%. The dietary history of a large group of infants was highly predictive of their risk for anemia . Continued consumption of breast milk until the age of 1 year is not warranted unless iron-fortified foods are given concomitantly. Because there is a problem with compliance, more successful and safe strategies for preventing iron deficiency woold included dual coverage in the from of therapeutic iron supplementation as well use of iron-fortified foods for teddlers who are at risk of iron deficiency.

It was performed to find out the influence of duck meat on human serum cholesterol level. The duck meat was canned and given to the subjects. In case of human, the subject was divided into two groups; such as a male group and a female group. Blood sample was collected from each subject during feeding period and the serum cholesterol was determined by Bloor method. The results were as follows: 1. In the male group, serum cholesterol level was 187mg% on the initial day, 184mg% on the 3rd day, 181 mg% on the 6th day, and 178.8mg% on the 9th day after feeding period passed. 2. In the female group, serum cholesterol was 184mg% on the initial day, 181.4mg% on the 3rd day, 178.2mg% on the 6th day, and 173.8mg% on the 9th day after feeding period passed.

The effect of feeding extracts from rhus trees on performance of broiler were performed to investigate development of natural antibiotic in process of broilers production. A total of 320 broiler chicks at 7 day of age were fed the commercial diet and water, water containing 0 ppm (control), 300 ppm (T1), 600 ppm (T2) and 1000 ppm (T3) of extracts from rims trees for 7 weeks. The body weight gain and feed conversion ratio were improvement by feeding extracts from rims trees at 7 to 21 days of age (P<0.05), but amount of feed intake and mortality were not different among the four group. When 21 to 35 days of age, body weight gain, amount of feed intake, feed conversion ratio and mortality were almost same results when 7 to 21days of age, but it was not significantly different. When 35 to 49 days of age, body weight gain in T1 and T3 group was significantly improvement than control group (P<0.05), also feed conversion ratio was improve by feeding extracts from rhus trees. There was a decrease in the microflora population of both E coli. and salmonella in the cecum contents and feaces in broilers by feeding extracts from rhus trees. Emission of ammonia and VFA gas from excreta were significantly decreased at 5 to 10 days of storaged period (P<0.05). The digestibility of dry matter, crude fat, and crude ash of feed were tend to increased in broiler feeding extracts from rims trees. Digestibility of crude protein of feed in broiler three treatmental groups was significantly improved (P<0.05) as compared with those in control group. These results indicated that the feeding extracts from rhus trees of 300 to 1000 ppm of broiler production were improvement in th6 body weight gain, feed conversion ratio, and mortality due to increasing nutrients digestibility from feed, decreasing of microflora population of both E coll. and salmonella in the cecum contents and feaces, decreasing emission of ammonia and VFA gas from excreta.

Some effect on the protein metabolism in growing albino rats by feeding on the rice mixed with wheat or barley have been studied. The species of wheat and barley used in this experiment were either 80% polished or nonpolished wheat, barley and naked barley. The growing rats to be examined were fed on 30% wheat or barley mixed with rice diets for 8 weeks. The total nitrogen, creatinine, amino acid nitrogen and urea-nitrogen contents in the liver and the creatinine and urea-nitrogen contents in the urine have been measured. The results obtained are summarized as follows: 1. The total nitrogen contents in the liver and the serum were no remarkable difference by feeding on each mixed diet, compared with the rice diet group. 2. The creatinine contents in the liver of the unpolished wheat and barley mixed diet groups were the similar to that of the rice diet group, but these were higher by feeding on the polished wheat and barley mixed with rice diets. 3. The amino acid nitrogen contents in the liver of the polished naked barley mixed with rice diet groups were the similar to that of the rice diet group, but these were higher by feeding on the other mixed diets than the rice diet. 4. The urea-nitrogen contents in the serum of the polished wheat and naked barley mixed with rice diet groups were higher than that of the rice diet group, but these were significantly lower by feeding on the polished barley mixed with rice diets than the others. 5. The creatinine and the urea-nitrogen contents in the urine of the original wheat and barley mixed with rice diet groups were higher than that of the polished wheat and barley mixed with rice diet groups. In the view of the above results, it could be seen that the protein metabolism was remarkable change according to polish of the wheat and barley.

This study was conducted to provide the basic information for nursing intervention in infant teach. ing and feeding situation. The subjects were 30 pairs of mother and her infant(9 month) who were normally delivered at 3 university hospital in Seoul area. The data collection was conducted by observation using videotaperecord from September 27, 1989 to Feburary 26, 1990 in their home. The measulsement tools used by this researcher were Nursing child Assessment Teaching scale (NCATS) and Nursing child Assessment Feeding Scale(NCAFS) which was developed by Barnard. The higher sum of "yes" score means the higher mother-infant interaction level. Mother-Infant interaction behaviors in both sitution were based on 6 subcategories; sensitivity to cue, response to distress, social-emotional growth fostering, cognitive growth 'fostering, clarity of + cues, and responsiveness to parent. The data collected through above method were analyzed by mean and t-test and the results were as follows. 1. The sum of maternal behavior score was 40.2 out of 50.0 in teaching situation and 37.9 out of 50.0 in feeding situation. Out of the 4 subcategories on maternal behavior in both situation, the highest subcategory was shown by response to infant's distress and the lowest subcategory by cegnitive growth fostering. 2. The sum of infant behavior score was 14.7 out of 23 in teaching situation and 17.9 out of 26 in feeding situation. Out of the 2 categories on infant behavior in both situation, the highest sub categroy was shown by the clarity of infant's cue in both situation. 3. There was a statistical significance between father's educational level and mother-infant interaction in teaching situation; college group was higher than high school group, particulary in category of sensitivity to infant's cue and congnitive growth fostering. 4. There was a statistical significance in teaching situation between mother's educational level and mother-infant interaction;college group was higher than high school group, particulary sensitivity to infant cue, social-emotional growth fostering and cognitive fostering. 5. There was no statistical difference in between parent educational level and mother.infant interaction in feeding situation.situation.
