The mean birth weight and weaning weight estimated from 777 kids from 30 bucks of Teddy goats were $1.67{\pm}0.31$ and $8.50{\pm}2.18kg$, respectively. The estimates of heritability of birth weight and weaning weight by half sib correlation method were $0.048{\pm}0.022$ and $0.101{\pm}0.012kg$, respectively. The high heritability estimates of birth weight indicates that selection on the basis of individual's own record will be effective. The low estimates of heritability of weaning weight indicates more emphasis should be given to improve environmental conditions for better achievement.

Vitamin B-6 status parameters of mothers were assessed in relation to th condition of the infant at birth and during the neonatal period. Parameters were assessed at birth and then weekly in 18 mother-infant pairs during the neonatal period ; mothers were supplemented postnatally with 2 or 27 mg PN-HCI/d. Vitamin B-6 inadequacy in the 2mg supplemented group was suggested by the vitamin status parameters. Mothers whose infants had unsatisfactory Apgar scores at 5min after birth(<7) had lower vitamin B-6 status parameters than mothers whose infants were scored satisfactory. Also, infants who scored unsatisfactory at birth and whose mothers were supplemented with the low level of PN had significantly lower vitamin B-6 status parameters at 7 days of age than infants who scored satisfactory. Infants scored unsatisfactory showed some beneficial effects in both vitamin B-6 status and growth associated with the higher level of maternal postnatal vitamin B-6 supplement. In summary, the mother's prenatal and postnatal vitamin B-6 intake were significantly related to the condition of her infant at birth and during the neonatal period, respectively.

In that marriage immigrant women' birth rate are higher than those of Korea women, they were selected to suggest pronatalism in Korea. The purpose of this study is to explore the child birth intention of marriage immigrant women. One of qualitative study, case study was used in methodology. Participants were 10 marriage immigrant women, depth interview were conducted. The major results were categorized facilitators and inhibitors. Facilitators were 'number of origin family members', 'absence or weakness of family planning', 'successful experience of the first child birth', 'no difficulty in childbearing', 'recommendation of mother-in-law', 'child' positive effect in Korea life adjustment'. Inhibitors were 'insufficient economic condition', 'husband' old age and the opposite of mother-in-law', 'dissatisfaction with marriage life', 'lack of government' support'. Based on this results, practical implications and interventions were suggested.

It is reasonably well known that there is a relationship between myelin formation and methylation of myelin basic protein in nerve cells. One of the suggestions is that arginine methylation of myelin basic protein could be of aid in the conjugation of myelin protein with the nonpolar lipid to form myelin. Abnormality in methylation of myclin basic protein might induce the neurological diseases in experimental animals as well as in human being. In the biological system, the methylation reaction is catalyzed by protein methaylse I using S-adenosyl-L-methionine as methyl donor. In this study, we examined the changes of S-adenosyl-L-methionine concentration and protein methylase I activity in developing rat brain tissues. The results are sumraerized as followings: (1) In brain tissues of fetus rat, the concentration of S-adenosyl-L-methionine was gradually decreased until to birth. However, the concentration in brain tissues of infant rat was suddenly increased at 7th day(just before myelination occur) birth. (2) Protein methylase I activity was decreased until to birth in brain of fetus rat and increased temporally just after birth, However, the enzyme activity showed no changes around 7th day after birth.

The objective of the study was to analyze the regional variance of late preterm birth (LPT: 34-36 weeks) by analyzing 2008-2012 birth certificated data of seven metropolitan cities (536,984 births: primiparous singleton birth) from Korea Statistics. The odds ratio and 95% confidence intervals were calculated from multinominal logistic regression analyses to describe the regional variance of LPT adjusted for maternal and infantile variables. The highest incidence of LPT rate by region were observed in Ulsan metropolitan city (3.7 percent), and the lowest in Deajon metropolitan city (3.1 percent). After adjustment by logistic regression for infantile sex, maternal variables, there was a significant increase in the risk of late preterm birth in Ulsan metropolitan city (odds ratio: 1.21) as compared with the incidence of LPT in Deajon metropolitan city. The odds ratio of LPT by region were 1.17 in Daegu metropolitan city, 1.13 Busan metropolitan city, and 1.12 in Incheon metropolitan city. More research is required to understand the risk factors for late preterm birth in this area including socio-demographic factors, medical factors, and regional and environmental factors.

This study investigated the effect of birth weight on the fertility of Holstein heifers. Growth parameter (body weight) was measured at birth. Calves were analyzed as three subgroups: low (L), average (A) and high (H) birth weight (BW) calves. LBW calves were born 10 kg lighter than HBW calves. Fertility data collected included age at first breeding (AFB), number of services per conception, pregnancy rate to first artificial insemination (AI), and age at first calving (AFC). Primiparous calves in HBW are smaller compared to multiparous cows (18.3% versus 48%). Although not significantly different, LBW offspring appeared to breed faster over the service period compared with the ABW offspring that bred three weeks later on the average. The mean pregnancy rate to first AI for LBW heifers was higher (60%) than ABW (48%) and HBW (45%). HBW cows required more services per conception (2.1) than the LBW (1.7) and ABW (1.9). There were significant differences (p<0.05) in age at first calving among the different calving birth weights. Smaller birth size did not have any subsequent adverse effects on fertility. HBW offspring were more likely or tend to have worse fertility parameters.

Purpose: The purpose of this study was to understand the lived experiences of nursing students' during Leboyer. Methods: Eleven senior nursing students were recruited from April to June in 2010. After completing informed consents, data were collected through in-depth interviews. All interviews were recorded and transcribed verbatim before analyzing. Nursing students were asked about their observational experiences during Leboyer births. Data were analyzed by using the Colaizzi style. Results: Interviews revealed 4 categories and 9 themes. The categories were: 'Respecting and blessing new baby', 'Keeping calm and joyful birth atmosphere', 'Reminding the meaning of nursing', 'Comparing Leboyer and convenience birth and making up their mind'. Conclusion: This study showed that observation of Leboyer birth is helpful for nursing students in order to have positive impression about childbirth. Furthermore, it is suggested that an exploration of the experiences of women and their husbands during Leboyer births would be helpful. On the basis of this study, it is concluded that the Leboyer birth, which focuses on baby's human right, should be introduced women's health nursing field as an effective birth strategy.

The study was carried out in Sahiwal, Holstein Friesian, Jersey and crossbred cattle and Murrah, Bhadwari, Jaffarabadi, Nagpuri and Surti buffaloes maintained at different organized herds to work out the polymorphism at growth hormone locus and study its effect on birth weight. A 223 bp fragment of the gene was amplified and digested with Alu I restriction enzyme. Two alleles, L and V with three genotypes LL, LV and VV were observed in Jersey, Holstein and cross bred cattle. Sahiwal cattle and buffalo were monomorphic for this locus producing only one genotype LL and one allele L. The frequency of L allele was comparatively higher in Holstein and crossbred cattle while in Jersey breed, the frequency of this allele was intermediate. The effect of genotype on birth weight was significant and LV genotype had higher birth weight than other genotypes. Hence, LV genotype in Holstein Friesian favored higher birth weight.

Purpose: This study tries to explore mothers' stress patterns and the related factors influencing mothers' stress over time after giving birth to premature babies. Method: Eighty four mothers who had given birth to premature babies were selected from Hospitals in B city. Data was collected using a self-reporting questionnaire that the mothers' stress level. Result: The mothers' stress after giving birth to premature babies gradually diminished and the stress pattern of mothers changed over time. Mother's age, occupation, income level, gestational period of the measures baby, weight at birth, nutrition type, lactation mode, number of complications, and existence or non-existence of an operation were analyzed as the factors that affected the mother's stress. Conclusion: The stress pattern of mothers giving birth to premature babies changed overtime. Based on the study results, it is considered that the nursing intervention programs should be developed in order to reduce the stress of premature baby's mothers with time elapse.

To investigate the trends in the survival rate (SR) for very low birth weight infants (VLBW) and extremely low birth weight infants (ELBWI) in Korea, a total of 43 articles pertaining to SR were analyzed, covering the years from 1967 to 2007. The changes in SR were compared using 5 year periods. The SR for VLBWI has increased remarkably, from 31.8% in early 1960 to 65.8% in early 1990 and 78.8% in early 2000. The SR for ELBWI has increased from 8.2% in early 1960 to 37.4% in early 1990 and 62.4% in early 2000. The SR has improved steeply since early 1990. When the SRs for VLBWI in Korea were compared with those in the U.S.A. and Japan, the figures were 40%, 72%, and 79% in 1985; 65.8%, 82%, and 86% in 1990; 71.3%, 86%, and 88% in 1995; 78.8%, 86%, and 89% in 2000, respectively. Although the recent SRs for VLBWI and ELBWI in Korea has improved rapidly, they have not yet reached the levels in these highly developed countries. To obtain accurate statistics that could be represented as an SR for premature infants in Korea, we have to develop a nationwide network database project.
