This study was designed to verify the effect of Doula-type-delivery nursing care on plasma $\beta$-endorphin, serum cortisol, related to delivery stress during labor, and postpartum anxiety of primipara by a quasi experiment(nonequivalent control group pretest-posttest design), from December, 1999 to August, 2000. The subjects of this experiment consisted of sixty eight primipara, with single gestation, full term, uncomplicated pregnancies, thirty three for the experimental group and thirty five for the control group. Their mean age was 26.1 years for the experimental group and 25.5 years for the control group. Their mean gestation period was 39.7 weeks for the experimental group and 40.1 weeks for the control group. As treatment, Doula-type-delivery nursing care was given for the experimental group. Data assessed plasma $\beta$-endorphin, serum cortisol during labor, and anxiety during postpartum. Plasma $\beta$-endorphin, serum cortisol were measured in the latent phase before treatment(pre-test) and the transition phase after treatment(posttest). Also, anxiety was measured in the latent phase before treatment(pre-test) and 24 hours postpartum after treatment(posttest). Data was analyzed by t-test, $x^2$-test, Repeated measures ANOVA with SAS Program. The results of this study were as follows; 1. Plasma $\beta$-endorphin was significantly elevated in the experimental group who were cared for with Doula-type-delivery nursing care during labor(P=.0463). 2. No significant group effects were found, but significant time effects were found for serum cortisol. 3. The postpartum anxiety of the experimental group was significantly lower than the control group(P=.0110). In conclusion, these findings indicate that Doula-type-delivery nursing care during labor could be effective in increasing maternal plasma $\beta$-endorphin and decreasing postpartum anxiety. Doula-type-delivery nursing care during labor could be applied as an effective nursing treatment for primipara.

Separation of the pubic symphysis in association with delivery is very rare. The Korean orthopedic and obstetrical literature pertaining to this syndrome is absent. The physiological widening is small and asymptomatic, but a separation of more than one centimeter may occur and is usually symptomatic. A twenty-six-year-old woman of separation of symphysis pubis associated with delivery was treated successfully with the treatment of reduction and pelvic band, with absolute bed rest in the lateral decubitus position.

A survey was carried out to investigate the effect of the parity on reproductive traits of Hanwoo(Korean native cows). Data on the reproductive traits of 670 Korean native cows were collected from January, 1996 to December, 1997 and analyzed by the parity. The results obtained were summarized as follows; 1. The average ages at first breeding, first conception and first calving were 443.0, 457.0 and 746.6 days, respectively. 2. The average days to first estrus after calving was 70.1 days and it was shortest in the cows with more than 5 parities (60.4 days) and longest in the cows at 4th parity (79.7 days). 3. The average number of services per conception was 1.53 and it was fewer in the cows at 2nd paity (1.43), but more in the cows with more than 5 parities (1.73). 4. The average days to first conception after calving was 91.2 days and there was a trend that it was longer as the parity of cows increased(p＞0.05). 5. The average length of calving interval was 375.3 days and it was shortest in the cows at 2nd cows (370.8 days) and longest in the cows at 4th parity (395.2 days).

Components of cholesterol, glucose, minerals (selenium, Ca, p) and vitamin E in blood and milk were collected and analyzed weekly after calving from a total of 78 Holstein cows. In this study, we examined changes of chemical components, correlations among them, and factors affecting the changes. The results were summarized as follows; 1 Average levels of components in blood during 9 weeks after calving were 178.8 mg/dl, 62.3 mg/dl, 8.9 mg/dl, 7.4 mg/dl, 52.2 ng/ml, $10.3{\mu}g/ml$, 16.3 mg/dl, 15.3 ng/dl, and 15.8 mg/dl for cholesterol, glucose, Ca, P, selenium, vitamin E, BUN (blood urea nitrogen), MSe (milk selenium), and MUN (milk urea nitrogen), respectively. 2. The levels of cholesterol, glucose selenium, vitamin E and MSe tended to increase over time after calving. 3. The estimated correlations among components were negative(-) for cholesterol and p, positive for selenium, and BUN and also positive for BUN and MUN. Glucose showed positive correlations with P and MSe. 4. For factors influencing the changes of components, there were significant differences in glucose and selenium for age, in selenium and vitamin E for parity, in glucose and MSe for milk and in all components except Ca and selenium for feeding grass and hay, respectively. In urea nitrogen, age and parity only showed significant difference in MUN. In conclusion, the results were suggested that changes of blood and milk components depend on feeding during the postpartum. Especially, we could ascertain that selenium in blood and milk is the important factor for the dairy cows after parturition.

The influence of stage of lactation on the moisture. total soilds, ash, calcium, phosphorus and Ca/P ratio of human milk was studied. A total number of 32 lactating mothers provided 101 samples collected at 4 consecutive stages of lactation : days o to 5 postpartum(colostrum); days 6 to 10 postpartum(transitional): days 25-35 postpartum(mature). and days 55-70 postpartum(mature). Moisture and total solids concentrations showed a little but significant difference at the 25-35 day stage as compared with those of colostrum and then remained stable, but ash levels decreased significantly with the elapse of lactation period. Calcium levels increased significantly from colostrum to transitional milk stage with a further less significant increase at mature stages. Between colostrum and transitional stages, phosphorus concentration showed a significant increase $(9.9\pm2.4$ vs $15.5\pm4.9$ mg/100 ml, p<0.001)but between the 25-35 day and the 55-70 day stage phosphorus values did not change significantly. Ca/P ratios for colostrum. transitional, the 25-35 day and the 55-70 day stages were 2.28, 1.76, 1.68 and 1.95, respectively. No significant relationship was found between ash. calcium, phosphorus or Ca/P ratio of milk and maternal parity. When modified milk formulas were reconstituted using the total solids of human mature milk as amount of the modified milk formula in 100 ml of infant feeding solution. ash, and Ca/P ratio were similar to those of human milk. However considerably higher concentrations of calcium and phosphorus exist in the reconstitution fluid than those observed in human milk.

This study was conducted to compare the delivery management including laboratory tests, medication and surgical procedures for the delivery in various medical facilities. Two university hospitals, two general hospitals, three hospitals, two private obstetric clinics, and two midwifery clinics in a large city were selected as they permitted the investigators to abstract the required data from the medical and accounting records. The total number of deliveries occurred at these 11 facilities between 15 January and 15 February, 1989 was 789 among which 606(76.8%) were vaginal deliveries and 183 (23.3%) were C-sections. For the normal vaginal deliveries, CBC, Hb/Hct level, blood typing, VDRL, hepatitis B antigen and antibody, and urinalysis were routinely done except the private clinics and midwifery clinics which did not test for hepatitis B and Hb/Hct level at all. In one university hospital ultrasonography was performed in 71.4% of the mothers and in one general hospital liver function test was done in 76.7% of the mothers. For the C-section, chest X-ray, bleeding/clotting time and liver function test were routinely done in addition to the routine tests for the normal vaginal deliveries. Episiotomy was performed in 97.2% of the vaginal deliveries. The type and duration of fluid infused and antibiotics administered showed a wide variation among the medical facilities. In one university hospital antibiotics was not administered after C-section at all while in the general hospitals and hospitals one or two antibiotics were administered for one week on the average. In one private clinic one pint of whole blood was transfused routinely. A wide variation was observed among the medical facilities in the use of vitamin, hemostatics, oxytocics, antipyreptics, analgesics, anti-inflammatory agents. sedatives. digestives. stool softeners. antihistamines. and diuretics. Mean hospital day for the normal vaginal deliveries of primipara was 2.6 days with little variation except one hospital with 3.5 days. Mean hospital day for the C-section of primipara was 7.5 days and that of multipara was 7.6 days and it ranged between 6.5 days and 9.4 days. Average hospital fee for a normal vaginal delivery without the medical insurance coverage was 182,100 Won for the primipara and 167,300 Won for the multipara. In case of the primipara covered by the medical insurance a mother paid 82,400 Won and a multiparous mother paid 75,600 Won. Average hospital fee for a C-section without the medical insurance was 946,500 Won for the primipara and 753,800 Won for the multipara. In case of the primipara covered by the medical insurance a mother paid 256,200 Won and a multiparous mother paid 253,700 Won. Average hospital fee for a normal vaginal delivery in the university hospitals showed a remarkable difference, 268,000 Won vs 350,000 Won, as well as for the C-section. A wide variation in the laboratory tests performed for a normal vaginal delivery and a C-section as well as in the medication and hospital days brought about a big difference in the hospital fee and some hospitals were practicing the case payment system. Thus, standardization of the medical care to a certain level is warranted for the provision of adequate medical care for delivery.

Purpose: This study was to test the effects of a full body massage on labor pain and delivery stress reaction for primipara during labor. Method: This study employed a quasi- experimental method(nonequivalent control group, pre-post test design). The subjects of this study were 57 primipara hospitalized at the U OB & GYN hospital in Inchon from November 1. 2001 to July 31, 2002. 28 women were assigned to the experimental group and 29 to the control group. The experimental group was given 20 minutes full body massage for each of three delivery phases. The control group was given conventional delivery care. The levels of labor pain were measured by the Visual Analogue Scale and the expression scores of the labor pain and the levels of delivery stress reaction were measured by pulse rate, respiration rate, and blood pressure, and State-Anxiety Scale. Data were analyzed using the repeated measures analysis of covariance(ANCOVA), t-test, $X^2$- test, simple ANCOVA with SPSS program. Result: There was no interaction effect between time and group(F=.370, p=.693), but significant time effects were found for subjective labor pain(F=3.840, p=.028). There was no interaction effect between time and group(F=.112, p=.894), but significant group effects were found for objective labor pain(F=12.299, p=.001). There was no interaction effect between time and group for PR(F=.172, p=.843), RR(F=.626, p=.539), SBP(F=.089, p=.915), DBP(F=.748, p=.479), but significant group effects were found for SBP(F=7.547, p=.008). The level of status anxiety of the experimental group was significantly lower than the control group(F=11.787, p=.001). Conclusion: This study showed that the full body massage has partially positive effect on labor pain and delivery stress reaction. Therefore this study suggested that the full body massage might be used clinically to help primipara during labor.

This study was designed to investigate between the semen characteristics and sperm chromatin structure in boar with different farrowing rates and relationship between fertility by AI and results of sperm chromatin structure assay (SCSA). The CASA (computer-aided sperm analysis) and SCSA were performed with liquid semen in boars. The all SCSA parameters based on the farrowing rates by AI were significantly differ (P<0.05). The significant negative correlations (P<0.05) were observed between all SCSA parameters and farrowing rate obtained by AI in the field. In conclusion, these results suggest that the sperm parameters evaluated in these studies may be useful indicators to predict the fertility by AI.

This study was designed to evaluate the changes in sperm motility, viability, HOST(hypo-osmotic swelling test), IVP(in vitro penetration), SCSA(sperm chromatin structure assay) during storage of liquid semen collected from boars with different farrowing rates using AI, and to find the relationship between boar fertility through AI and sperm diagnostic parameters during semen storage. The results of HOST were significantly decreased according to the increasing of in semen storage days and the results of IVP were significantly decreased at 3 days of semen storage (P<0.05). The %Red was significantly different among the >80%, 70󰠏80% and <70% farrowing rate group at semen storage day 6(P<0.05). The correlation coefficients between the %Red and farrowing rate were increased according to the semen storage. In conclusion, these results suggest that the sperm parameters evaluated in these studies may be useful indicators to predict the fertility of AI and evaluate the semen quality in boars.

Obstetric problems concerning macrosomia were evaluated by retrospective review of 91 pregancies that resulted in the delivery of an infant weighing 4,000gm or more at the Yeungnam University Hospital during 3 1/2 years from Jun. 1983 to Oct. 1986. The results obtained were as follows. 1. Macrosomic infants weighing 4.000gm or more occured in 2.8% of the deliveries. 2. 65.9% of macrosomic infants and 53.5% of total infants were male. The ratio of male was statistically higher in the macrosomic infants than in the total infants(P<0.05). 3. The incidence of macrosomia was higher with increasing qestational age, and deliveries at 42 weeks or more gestation were more common in the macrosomic infants than in the total infants(P<0.01). 4. The incidence of macrosomia was highter with increasing parity, and stastically higher in the multipara than in the primipara(P<0.01). 5. There was no difference in the incidence of macrosomia between the mothers aged 24 or less and that of 30 or more. 6. The cesarean section rate of macrosomia(30.8%) was stastically higher than that of the total infants(15.7%)(P<0.01) 7. With the pregnacy and delivery of macrosomic infants, 22 antepartum anemia(24.2%), 10 postpartum hemorrhage(11.0%), 9 birth canal injury(10.0%), 7 prolonged second stage of labor (7.7%), 4 breech presentation, and 3 pregancy induced hypertension occured in the mothers, and 10 asphyxia(or Apgar score 6 or less), 2 shoulder dystocia, 1 intrauterine fetal death, and 1 sacrococcygeal teratoma occured in the infants.
