This study presents results of surveys conducted Seoul and Kangreung public health center using structured questionnaire developed by researchers to identify factors that were relevant to the method of feeding. To compare the infant's development between the breast-fed infants and formula-fed infants, infant's height, weight, triceps skinfold during 1month and 4months were cheked. The results were as follows : 1. At postpartum, 59.1% infants had formula feeding, while 22.6% had breast feeding. At 1 month old, 49.6% infants had formula feeding, 27.8% had breast feeding. At 4 months old, 60.9% infants had formula feeding, while 26.1% had breast feeding. 2. 'Lack of breast milk' was the predominant reason for formula feeding. 3. The sujects didn't enough eat not only rice and seaweed soup but also any other specific foods during breast feeding period. 4. Factors that affected the method of feeding were the patterns of delivery, mother's height & weight, first baby feeding type(at post partum), infant sex, mother's age, preparation of breast feeding, first baby feeding type, regular clinic visit (at 4months old). 5. The birth weight and height were correlated with mother's weight and height. 6. There were no significant different on infant's weight, height, triceps skinfold between breast-fed infants and formula-fed infants.

The purpose of this study is to investigate breast-feeding and breast-feeding health behavior among korean first-time mothers and to provide basic data for promoting breast- feeding. Data were collected by interview or self report from 444 first-time mothers who visited health clinic center in the area of metropolitan, medium or small city, countryside. and whose infants were under 12 months old from January 2001 to February 2001. The results show that breast-feeding was 31.5% in a week after childbirth, 25.8% in 4 weeks after childbirth, 22.7% in 2 months, 17.8% in 3 months, 14.3% in 6 months, 2.5% in 12 months after childbirth. Breast-feeding rate was very low in Korea and the duration of breast-feeding was very short. Breast-feeding health behavior did not show significant differences by general characteristics of the subjects except area. The subjects in the health clinic center with MCN project did better breast feeding health behavior than the subject in the health clinic center without MCN project. To raise breast-feeding rate, several strategy could be suggested. Systemic education about importance and advantages of breast-feeding and desirable breast-feeding method should be provided to pregnant women and postpartum women. Childbirth leave in the work should be prolonged, and supportive facility such as nursery room should be installed for working mothers. Hospitals should follow the guideline of 'Baby Friendly Hospital Initiative' which was provided by UNISEF and WHO, including rooming-in after delivery.
In this study, I made researches of 510 mothers who breed their infants in total (256 boys & 254 girls), among which 410 in urban area and 100 in the rural area, as an object of the investigation so as to make an intensive examination and analysis of the actual state of feeding nutritive method, grasp several related factors, and finally suggest the elementary data for both campaign encouraging breast feeding and the infant feeding education. 1. Mothers showed the meaningful local differences as in an education and income level at 1% and as in a delivery type at 5%. 2. To have decided the feeding conditions according to the residences by the Kaup index distribution (P<0.05) resulted in a meaningful difference according to regions and also made us be more thoughtful of the overnutrition in the urban area than in the rural area, and it didn't showed a meaningful difference the nutritive state according to the infant feeding method thought desirable (P<0.01). 3. The feeding methods consist of breast feeding at 21.8%, artificial feeding at 48.8%, and the mixed one at 29.4%. As for the feeding method thought desirable, breast feeding was 52%. Even though they were thinking that breast feeding is better, the breast feeding case didn't go beyond 32.5% only and as for the actual feeding methods it showed a meaningful difference according to the feeding method thought desirable (P<0.01). 4. Regarding the reasons why they chose breast milk, it was 64%, the most because mother's milk contains the immune system, 63.1% for the baby's health, 52.3% because of its most because breast milk is of little quantity, 37.8% because of the mother's occupation, 14.1% because they have fed the baby artificially from the beginning and so on. Considering the reasons why they chose the mixed feeding, it was 70.7%, the most because the amount of breast milk a little, 27.3%, the next one, because of the mother's occupation and so on. 5. The respondents who answered that how to increase the number of breast feeding population depends on the reinforcement of breast feeding education for the women were 190 (37.3%), the most among all 150 persons and those who had the opinion that they should spread and actualize the temporary childcare rest (from office) system for the women who have jobs were the secondly most, 107 (21%).
This descriptive study was done to investigate the proportion of mothers breast feeding and identify factors which influence breast feeding. The subjects were 320 mother who child under five years of age, living in WonJu and their children who numbered 530. Data collection was conducted at various places in the WonJu area using survey questionnaire. The results were as follows : 1. The proportion of children receiving breast feeding was 23.3%, mixed feeding 31.7%, milk feeding 45.1%. The most frequent duration for breast feeding was one month, the mean duration was six months. 2. The major reasons for breast feeding were for the health of the child 52.5%, for emotional attachment with the child 34.2%, and as the expected way of feeding 29.5%. 3. The major reasons for interrupting breast feeding were jobs 26.1%, illness of the child or mother 16.1% abnormality of the breast of nipple 12.7% others 31%. 4. The major reasons for quitting breast feeding were insufficient breast milk 34.5%, job 19.6%, diarrhea in the child 9.9%. 5. The factors influencing breast feeding were educational status and the presence of a job. 6. The husband's attitude to breast feeding was very positive 82.3% and the subjects were supported by their mothers and husbands. But the major information sources about breast feeding were the mass media 30.4% and relatives 22.0%. 7. The breast feeding mother reported experiencing positive and satisfactory feelings, but the milk feeding mother reported experiencing negative and guilt feelings. Also the breast feeding mothers perceived their children as very healthy with a stable emotional status. The results showed the breast feeding ratio in WonJu to be very low and problematic and the subject mothers strongly need information about breast feeding and support while breast feeding. Therefore it is recommended that an education program for community women and other people, like husbands, and grandmothers, be developed along with an education program for university students and other young people to provide them with preparatory information as they begin to think about marriage and families.
Growth patterns of Saccharomyces cerevisiae NS 2031 and its total RNA contents were observed by a fed-batch fermentation with different media-feeding methods. With an exponential feeding pattern, both final cell concentrations and intracellular RNA contents decreased with increasing feeding rates. Intracellular RNA contents also decreased with the growth time. At the same feeding rate of the exponential pattern, final cell concentrations decreased with the increase of total sugar concentration whereas intracellular RNA contents increased. The highest cellular yield was 0.47 at the total sugar concentration of 10%. With increasing feeding rates of the parabolic feeding pattern, final cell concentrations decreased whereas intracellular RNA contents increased, showing a different tendency from the exponential feeding pattern. In comparison of two feeding methods, the exponential feeding pattern was better than the parabolic feeding pattern in terms of cell growth, cellular yields and intracellular RNA contents of Saccharomyces cerevisiae NS 2031. Also, the intracellular RNA contents of the exponential feeding pattern was found to be about 2% higher than that of the parabolic feeding pattern at the same instantaneous growth rate $({\mu}_{inst})$.
Melatonin plasma in Swallows exhibited circadian rhythmical secretions in the LD (Light and dark, 12:12) period with and without feeding. But their average difference between at CT6 (Circadian Time) and CT18 was 3.53 ng/$\textrm{m}{\ell}$ in LD period with feeding. on the other side 1.60 ng/$m\ell$ during without feeding. Melatonin concentration at CT6 without feeding incresed from 0.22 ng/$\textrm{m}{\ell}$ to 0.93 ng/$\textrm{m}{\ell}$. It is demonstrated that decresing melatonin secretion may reduce digestive function in order to ready for the migration. While the birds with feeding exhibited circadian rhythmical activity, their activity without feeding was durable. The concentrations of melatonin plasma by refeeding were 1.53 ng/$\textrm{m}{\ell}$ at CT6 and 6.07 ng/$\textrm{m}{\ell}$ at CT18. Melatonin plasma concentration in the night increased by more than ca. quadruple at day. This results suggest that melatonin regulates metabolism for the return to the normal metabolism condition after migration. After 3 days refeeding melatonin was secreted circadian rhythmically same as the secretions with feeding at beginning.
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.
A 15-minute questionnaire on breast-feeding was administered to the obstetric and pediatric residents and nurses in metropolitan academic training programs in Korea to assess their attitudes to and knowledge about breast-feeding and their confidence in managing breast-feeding problems. The questionnaires were self-administered and confidential and the participants was 279. Overall, the study participants indicated a supportive attitude toward breast-feeding. Nurses had a highest supportive attitude than obstetric and pediatric residents. Their self-confidence in this area was inappropriately high with 48% of total, 49% of obstetric, 42% of pediatric and 58% of nurses describing themselves as "confident" or "very confident" to manage common breast-feeding problems to compare their knowledge level answering only 46% of the questions correctly. However, nurses who did have continuing education about breast-feeding had significantly high in knowledge level. These health care professionals have extremely limited knowledge of breast-feeding management compared to their reported confidence. To be truly supportive of breast-feeding, health care professionals should receive didactic and clinical training to breast-feeding management.
This is a study on types of foodservice system, the menu, role of the Dietitian, management of the facilities and utensil through the survey conducted at 105 enterprises located in Seoul industrial foodservices which were evenly divided into three groups ; large size of feeding group, medium size of feeding group, small size of feeding group. The sresults are below, 1. Most institutional foodservice was enterprise under direct management. 2. Selective menu was set for the large size of feeding group than small size of feeding group. At budget making, personal management and purchansing management, the dietition role was not important in the large size of feeding group than in the small size of feeding group. 3. Equipped rate of facilities and utensil were greater volume for the large size of feeding group.
Data center is an information hub and resource for information-centric society. Since data center houses hundreds to ten thousands servers, networking and communication equipment, and supporting systems energy saving is one of the hottest issues for green data center. Among several solutions for green data center this paper introduces higher voltage direct current (DC) power feeding system. Contrary to legacy alternating current (AC) power feeding system equipped with Uninterruptible Power Supply (UPS), higher voltage DC power feeding system is reported to be a more energy efficient and reliable solution for green data center thanks to less AC/DC and DC/AC conversions. Main focus of this paper is on reliability issue for reliable and continuous operation of higher voltage DC power feeding system. We present different types of configuration of the power feeding systems according to the level of reliability. We analyze the reliability of the power feeding systems based on M/M/1/N+1/N+1 queueing model. Operation of the power feeding system in case of failure is also presented.
