This descriptive study was cone to investigate the incidence of and reasons for the interruption of breast-feeding by married nurses. For this purpose, data was collected from married nurses, each of whose last child was under five years old, living in Seoul, Tong Hae, Sam Chok and Kang Rung. The number of children involved was 208. The data was collected from various places in Seoul, Tong Hae, Sam Chok and Kang Rung area, using 150 survey questionnaires. The results of the study were as follows: 1. The proportion of children receiving breast-feeding was 1.4%, mixed feeding 33.8% and milk feeding 64.9%. The most frequent duration of breast-feeding was one month (80.2%). 2. The major reasons for breast-feeding were the health of the child 97%, and for emotional attachment with the child 75%. 3. The major reasons for interrupting breast-feeding were the job of mother 79.5%, and an abnormality of the breast or nipple 26.0%. 4. The major reasons for quitting breast-feeding were the job of mother 89.2%, insufficient breast milk 34.2%, and breast pain 19.9%. The above results suggest that the breast-feeding ratio in married nurses is very low. Therefore it is recommended that education about and propagation of breast-feeding be carried out. To enhance and promote breast-feeding, hospital managers should provide a comfortable environment, which is conducive to breast-feeding.

This study investigated the effect of different light intensities on first feeding of chub mackerel Scomber japonicus larvae. Fertilized eggs, obtained from LHRHa-induced spawning of captive broodstock, were stocked (60 larvae/l) into twelve 30-1 aquaria under light intensities of 0, 100, 200, 500 and 1000 lx, with three replicate aquaria per treatment. Temperature was maintained at $20^{\circ}C$ and salinity was 35 psu. Larvae were fed the rotifer Brachionus rotundiformis at a density of five rotifers/ml. Feeding incidence was measured as the percentage of larvae with prey in the digestive tract. Feeding intensity was evaluated as the number of prey in the digestive tract of the larvae. Larvae fed in darkness (0 lx) had significantly lower (P < 0.05) feeding incidence ($13{\pm}0.05%$ larvae with prey) and feeding intensity ($1.00{\pm}0.05$ rotifers per larva) than those larvae fed at 100 ($30{\pm}0.07%$, $1.17{\pm}0.09$ rotifers per larva), 200 ($43{\pm}0.08%$, $1.24{\pm}0.11$ rotifers larvae$^{-1}$), 500 ($53{\pm}0.08%$, $1.48{\pm}0.14$ rotifers per larva) and 1000 lx ($60{\pm}0.08%$, $1.38{\pm}0.13$ rotifers per larva). The feeding incidence of S. japonicus larvae increased with light intensity while feeding intensity showed no significant difference (P > 0.05) between light treatments.

A survey was carried out to investigate the symptoms and occurance of reproductive disorder in Hanwoo(Korean native cattle). Data of the reproductive disorder of 561 heads from 28 farm households have been collected from Dec. '95 to Nov. '96 and analyzed calving no, nutritional body condition and housing forms. The results obtained are summarized as follows: 1. The incidence of reproductive disorder was 20.1% and the major common symptoms were repeat breeding(39.8%), anestrous(31.0%), nymphomania(10.6%) and subestrous(8.9%). 2. The incidence of reproductive disorder according to the calving no., that of heifer, calved one to two calving no. and over three calving no. were 20.6%, 13.9% and 34.5%, respectively. 3. Reproductive disorder incidence according to the nutritional body condition was 18.3%, 14.6% and 48.7% at body condition score(BCS) less than 2.0, 2.5 to 3.0 and over than 3.5, respectively. At BCS over 3.0, the symptoms of common reproductive disorder were repeat breeding(17.6%), anestrous(12.2%), nymphomania(10.8%) and subestrous(2.7%). 4. The incidence of reproductive disorder according to the housing form 15.8% and 34.6% for group feeding in open house and individual stanchion feeding in stall, respectively. In group feeding, reproductive disorder incidence of cows raised in space of more than 9.9$m^2$ per head was 14.1%, while that of cows raised less than 9.9$m^2$ per head was 18.2%. And incidence of repeat breeding, aneestrous and subestrous was more frequent in individual stanchion feeding than group feeding.

In order to investigate the relationship between the incidence of displaced abomasum and feeding, the actual feeding practices and chemical compositions of roughage were examined in 2 kinds of farms at Tokachi district in Hokkaido. Examination of animal health records revealed that the annual milk yield per cow in high incidence (H-DA) farms was significantly higher than that in low incidence (L-DA) farms. The amount of concentrates fed in H-DA farms tended to be higher than that in L-DA farms during lactation. Compared to L-DA farms, the amount of juicy roughage (corn silage and grass silage) and dry roughage (hay, hay cube and roll wrap silage) during lactation in H-DA farms tended to be higher and lower, respectively. Moreover, the amount of roughage and the ratio of roughage to concentrates in H-DA farms tended to be lower than in L-DA farms. The survey indicated that displaced abomasum was associated with insufficient feeding of dietary fiber and overfeeding of concentrates.

Purpose: The purpose of this study was to investigate the difference in the incidence of diarrhea among the subjects given hypertonic and isotonic nutrients to the nasogastric tube feeding patients in the a critical care setting. Methods: This study is aquasi-experimental study with a pre & post-test design. The sample size of 40 was calculated based on Cohen's formula (1988). The total of 40 subjects who signed the informed consent were randomly selected and divided evenly into two groups, experimental and control group. Results: There are no significant differences between the two groups in homogeneity test (sex, age, albumin level, the use of antibiotics, antacid, and $H_2$ blocker). However, the frequencies of occurrence in diarrhea according to the density of nutrients formulation indicated a statistical difference at the level of .005 (p=.001): diarrhea occurred in four of 20 (20%) of the experiment group, but 14 (70%) of the control group. Also the onset date of diarrhea in the experiment group is later than that of the control group. Conclusion: The research findings suggest that we should begin with low density nutrients for nasogastric tube feeding, and increase its density gradually to decrease diarrhea incidence in the critical care setting.

In order to obtain baseline data for the development of an educational program on breastfeeding, a survey was carried out to investigate infant feeding practices, the characteristics the subjects have in common, and the factors that influence the feeding methods among women in Seoul and the Chungbuk area. Subjects included 671 lactating mothers who visited public health centers or pediatric clinics between December 1999 and February 2000, and were interviewed using a questionnaire. The results were as follows : With respect to feeding methods, the incidence of breastfeeding, formula feeding, mixed feeding and formula feeding switched from breastfeeding was 20.6%, 29.8%, 11.6%, and 38.0%, respectively. With respect to the characteristics the subjects had in common, the incidence of women who planned their infants' feeding methods before pregnancy, during pregancy, and after delivery was 48.7%, 31.0％, and 20.3%, respectively. The incidence of women who started breastfeeding in the hospital after delivery was 38.8％. About seventy seven percet of the subjects had not previously attended an educational program on breastfeeding, and most of these wanted to participate in the future in an educational program to learn about breastfeeding. Some of the topics they were interested in were“Nutritional Management for Sufficient Breast Milk”(60.3%),“Breast Care”(25.0%), and“Correct Nursing Positions”(9.8%). Most (88.2%) of the women who breastfeed suffered from physical discomforts including discomfort of the waist, and legs and discomfort due to cracked or sore nipples. “Insufficient breast milk”was the main reason for breastfeeding cessation or for switching to formula feeding. With respect to formula feeding practices, the main reasons for selecting a specific brand of formula were“the same brand the hospital used after delivery”(34.3%) and“an advertised brand”(23.3%). The strongest factor for promoting breastfeeding was“the support of husband or parents”, next were “breastfeeding in the hospital after delivery”and“planning to breastfeed before pregnancy”in that order. The characteristics the subjects had in common relating to formula feeding were“mother's job”,“high economic level”,“Caesarian section”and “planning to breastfeed after delivery”. In conclusion, it is recommended that breastfeeding be pro-moted, and educational programs be developed and offered as soon as possible to each group which had unfavorable attitudes toward breastfeeding. In addition, the monitoring and supervision of formula advertisements is required to protect consumers from the adverse effects of exaggerated advertising.

This survey was conduced to investigate the feeding methods of mothers in Suwon, Kyungkido. Incidence of breast feeding was 29.9eA of the Interviewed mothers, which showed lower percentages than those of previous surveys. The jai or factors influencing the method of infant feeding were generally depended on mother rather than infant. The mothers who had a higher income and a higher academic career tended to pre(or the bottle feeding to the other. md first birth order made them select the breast feeding rather than the other. Generally mothers knew the information about infant nutrition very well (91.0%), but their knowledge actually did not work. The sources of mother's Information on the Infant nutrition were the books of rearing infants and magazine. But there were some discrepancies between the actual and needed source of information : i.e. mothers wanted to acquire their information from mass communication.

We surveyed the incidence of urinary calculi for feeding period, urinary lesion, composition of calculi and changes of serum chemistry with Korean native castrated steers, which are growing until 26 through 31 months. Without showing any clinical signs such as urethral obstruction, hydronephrosis and strangury for all group, $37.8\%$ (34 out of 90) of Korean native steers carried urinary calculi in carcass. The incidence of urine calculi far different feeding stages from 26 to 31 months were observed as $13.3-60.0\%$er, no significant differences were detected. The distribution of calculi were kidney $(24.4\%)$, kidney and bladder $(10\%)$ and kidney, bladder and urine $(3.3\%)$. Congestion of urinary bladder was shown in $26.6\%$ of Korean native steers. Korean native steers with urinary calculi $(41.2\%)$ had more possibilities (P<0.05) to bring outbreaks of congestion of urinary bladder than those of without calculi $(17.8\%)$. The main composition of calculi were struvite (magnesium ammonium phosphate crystals), calcium phosphate, calcium carbonate, calcium oxalate, non-oxalate calcium, ammonia and phosphate. The distribution of urine pH was $71.7\%$(above pH 8.0), $12.2\%$ (between pH 7.0 and pH 8.0) and $16.6\%$ (under pH 7.0). Like shown in herbivores, most of the urine pH was distributed as alkaline urine. Serum creatinine was shown significant difference (P<0.05) according to incidence of calculi but other serum chemistry didn't show any difference in serum chemistry. These results suggest that feeding until 26 to 31 months in Korean native steers castrated at 6 months of the age elicits urinary calculi and congestion of urinary bladder, but not clinical abnormality. And adjustment of the dietary Can ratio to a level of 2:1 or greater during feeding period may reduce the possibility of incidence of urinary calculi in Korean native steers.

This study was designed to assess the current status of infant feeding through an retrospective survey on feeding method. The survey was executed for 417 mothers bringing up a child below 24 months in Seoul and Kyunggi-Do province from September to October, 1993. Analysing a few influential environmental factors while assessing the level of knowledge today's mother have on infant feeding. Incidence of breast feeding was 27.8% of the interviewed mothers, which showed lower percentages than those of previous surveys. This research proved the major influencing factor generally depended on its mother rather than babies. Generally mothers knew the information of infant feeding, but their knowledge actually didn't work. The source of mothers' informations on the infant nutrition showed the grandmother, books and magazines, doctor were many by the order. among the reasons of resent formula and mixed feeding, lack of breast milk' was the commonest as 50.5% and the next reason was 'because of job' as 12.6%.

Over the past 20 years, neonatal mortality rates for preterm infants, particularly those born extremely preterm and with a very low birth weight, have decreased steadily. As more very immature preterm infants survive, provision of enteral feeding has become a major focus of concern. According to many experts on neonatal nutrition, the goal for the nutrition of preterm infants should be to achieve a postnatal growth rate approximating that of a normal fetus of the same gestational age. Total parenteral nutrition for maintaining nutritional integrity is mandatory before successful transition to enteral feeding. Early initiation of trophic enteral feeding is vital for postnatal adaptation. Recently published randomized controlled trials provide no evidence to support the practice of postponing enteral feeding to reduce the incidence of necrotizing enterocolitis. Early trophic feeding yields demonstrable benefits and there is currently no evidence of any adverse effects following early feeding. Preterm milk from the infant's own mother is the milk of choice, which can always be supplemented with a human milk fortifier. Here we review over 50 randomized controlled trials and over seven systematic reviews published on neonatal parenteral and enteral feeding of preterm infants. Neonatologists must make use of the evidence from these studies as a reference for feeding protocols for preterm infants in their NICUs are to be based.
