This study investigated the effects of maternal undernutrition during late pregnancy on lamb birth weight. 45 Mongolian ewes, synchronized for oestrus and then mated, were divided into four groups and offered 0.86 MJME/kgw-0.75d-1 (control group; CG : ad libitum access to feed), $0.44MJME/kgw^{-0.75}d^{-1}$ (Restricted Group 3; R3), $0.33MJME/kgw^{-0.75}d^{-1}$ (Restricted Group 2; R2) and $0.20MJME/kgw^{-0.75}d^{-1}$ (Restricted Group 1; R1) respectively during late pregnancy (90-150 days). During restriction, maternal net body weight loss, insulin and NEFA concentrations and lamb birth weight were measured. The results indicated that loss of maternal body weight in R3, R2 and R1 was 4.42, 7.23, 11.13 kg respectively, which was significantly (p<0.01) higher than that in CG (0.93 kg). Insulin concentrations of the ewes in R1, R2 and R3 were lower and were significantly different (p<0.05) between restricted groups and CG at 124 d of pregnancy. NEFA concentrations in all groups tended to decrease from 90d of gestation to parturition and in R1 were significantly (p<0.05) lower than in CG at 124 d of gestation. Lamb birth weight in R1 was significantly lower than in R2, R3 and CG (p<0.05). In conclusion, with decreasing supply of maternal nutrition, the retardation of fetal growth became worse. When the plane of nutrition was below $0.33MJME/kgw^{-0.75}d^{-1}$, significant effects of maternal undernutrition on lamb birth weight were observed.

Myelin basic protein (MBP), a major structural protein of the myelin, is thought to be important for the maintenance of myelin in the central nervous system (CNS). We investigated the effect of maternal folic acid nutritional status on the folate level and the synthesis of MBP in the offspring. In order to test this hypothesis, female Sprague-Dawley rats were fed either folic acid sufficient (8 mg/kg diet) or deficient (0 mg/kg diet) diet from 2 wks prior to the mating throughout the entire pregnancy, lactation and weaning period. We examined plasma folate level by the radioimmunoassay and homocysteine level by HPLC, respectively. The MBP expression was measured by the western blot analysis. The maternal folic acid deficiency decreased plasma folate level with a concomitant increase in plasma homocysteine level in their offspring. The maternal folic acid deficiency decreased hepatic levels of SAM and SAM/SAH ratio with a concomitant increase in hepatic levels of SAH and the MBP expression of spinal cord in their offspring at 7 wks of age. These results suggest that maternal folic acid nutritional status affect plasma folate and homocysteine level in their offspring. Moreover, the maternal folic acid deficiency mi호t inhibit the MBP expression of the spinal cord and disrupt many other vital CNS reactions in their offspring.

A comparative study was conducted to identify the effects of prenatal education on primiparas' self-confidence, satisfaction in maternal role performance and perception of delivery experience. Data were collected from 91 primiparas from August 1 to 30, 2001 using structured questionnaires. The subjects were selected from 2 OB & GY hospitals which operate the same prenatal education programs in M city. One group of subjects was primiparas who did receive prenatal education (n= 44) and another group of subjects was primiparas who did not receive prenatal education (n= 47). This study hypothesized that primiparas in education group would have higher self- confidence, satisfaction in maternal role performance and perception of delivery experience than those of non-education group. Descriptive statistics, $x^2$-test, t-test, and correlation were used for data analyses. The results of this study were as follows: 1. Primiparas in prenatal education group would not have better perception of delivery experience than those of non-education group (t=1.405, p = 0.163). 2. Primiparas in prenatal education group would have higher self-confidence in maternal role performance than those of non-education group (t=7.669, p=0.000). 3. Primiparas in prenatal education group would have higher satisfaction in maternal role performance than those of non- education group (t=4.115, p = 0.000). 4. There was significant correlations between self-confidence and satisfaction (r=0.489, p=0.000). Moreover, there was significant correlation between self-confidence and perception of delivery experience (r = 0.284, p = 0.006). The results of this study indicated that prenatal education needs to be developed and applied to nursing practice to increase self-confidence and satisfaction in maternal role performance. Experimental studies are needed to identify the effect of prenatal education.

Objective: The effects of maternal and offspring dietary vitamin A (VA) supplementation on early body weight, digestive tract function and immune function in goslings were studied. Methods: Yangzhou geese (180 d old) were randomly divided into 5 experimental groups of 15 females and 3 males (the males were kept until slaughter). Eggs were collected for hatching during the peak laying period. A total of 96 goslings were selected from each treatment group (each fed a basic diet supplemented with 0, 4,000, 8,000, 12,000 or 16,000 IU/kg VA) and randomly divided into 2 groups, with 6 replicates in each group and 8 goslings in each replicate. The gosling diet was supplemented with 0 or 9,000 IU/kg VA. Results: i) Villus length, villus width and the muscle thickness of the duodenum, jejunum and ileum were increased and the crypt depth was reduced after adding 12,000 IU/kg VA to the goslings' diet (p<0.05). Adding 9,000 IU/kg VA to the offspring diet increased the length of the duodenal villi and width of the ileum and decreased the crypt depth of the ileum (p<0.05). ii) Supplementing the maternal diet with 12,000 IU/kg VA increased immune organ weight, the immune organ index and immunoglobulin content in goslings (p<0.05). The bursa weight and immunoglobulin G content of offspring were higher in the 9,000 IU/kg VA supplementation group than in the group with no supplementation (p<0.05). Conclusion: Offspring growth and development were affected by the amount of VA added into maternal diet. The negative effect of maternal VA deficiency on offspring can be compensated by adding VA to the offspring diet. Continued VA supplementation in the offspring diet after excessive VA supplementation in the maternal diet is unfavorable for gosling growth and development.

The postpartum is a period of transition to motherhood where a childless woman transforms into a woman with children. Parents, especially mothers must perform an essential role of implementing instrumental and emotional care behaviors on part of the helpless, dependent, and immature infant. First-time mothers, however, suddenly face the responsibility of round the clock duty without neither parenting training during pregnancy, nor a time to gradually adapt to growing responsibilities after birth, with confusion and frustration as a result. Thus, after providing first-time mothers with childcare education as maternal role preparation, this study will try to examine its effects on childcare behaviors and confidence in maternal role during the early postpartum period. This quasi-experimental study using a nonequivalent control group non-synchronized design, was carried out from March 1995 to May 1996 to verify the effects of a childcare education program with first-time mothers who had vaginal delivery in Ewha University Hospital, Seoul, Korea, and collected data from 60 subjects who consented to the study. The education was given in the early postpartum period(48-72 hours after delivery) and to measure its effects, a posttest was done 4 weeks later with the results analyzed by SPSS shown in the following : 1. The childcare behavior score of the experimental group that had received the newborn care education was higher than the control group(t=3.5, P=.001). 2. The control group and the experimental group which had received the education showed no difference in degree of confidence in maternal role. 3. The higher the childcare behavior score, the higher the degree of confidence in maternal role was among the subjects(r=.56, P=.001). The preceding results are significant in that childcare practices can be promoted by providing child-care education to first-time mothers in the early postpartum period. Thus, this education can be used as a nursing intervention strategy in the early postpartum period.

This study was carried out to investigate the effect of changes in child care technology on mother-child contact by using all sorts of literature such as diaries, documents or statistical data. Child care technologies began to change during the 1960's. Diverse goods and services such as baby dry milk, paper diapers and child care centers have made child care easier and saved a great deal of time. This has also allowed women to participate in labor markets easily despite rearing children. But maternal contact with children have declined due to new goods and services and this trend is especially prevalent in early childhood. It could be supported that the convenience of rearing rather than the needs of children like as attachment to maternity primarily was considered in technological change. From this results it was suggested that we should develop the alternative child care technologies which better reflect children's needs.

We had examined the levels of specific IgG and IgA to dietary antigens in human breast milk and the relationships between the maternal food intake and the specific antibody level. The highest antibody titers were found in colostrum and decreased as lactation progressed. The specific antibody level was not affected by maternal calorie or protein intake, but affected by the intake frequency of a kind of food. Egg and meat intake significantly related to anti-OVA IgG and anti-BSA IgA antibodies, respectively. Meat intake frequency was generally affected by the other specific antibody levels.

The main purpose of this study was to examine the relationships among Mother's Conversation Patterns, Maternal Emotional Support, and Children's self-esteem and motivation to achieve. The subjects of the study were 262 children's in the 5th and 6th grades at an elementary school in Seoul and Gyeonggi. The major results of this study are as follows: The achievement motivation of female children was higher than that of male children. Second, the mother's conversation patterns, maternal emotional support and children's self-esteem were related to the children's achievement motivation. Third, according to the results of an examination of the relative influence of the variables, the child's self-esteem and mother's open communication had an effect on the child's achievement motivation. This high level of self-esteem and motivation to act positively led to high achievement motivation.
