Background: The change in size and weight of the female reproductive organs during gestation and birth might be affect the perineal muscles and this condition in dairy cow not been reported. This study aimed to assess the ultrasonographic image of coccygeus muscle in 11 inseminated dairy cows with different gestational ages and postpartum. Methods: Gestational age was calculated based on the record of artificial insemination and confirmed by using transrectal brightness mode ultrasonography. Perineal hair between the sacrum and ischium bones was shaved along 3-5 cm before being ultrasound. The images of perineal area were obtained by transcutaneous ultrasound using a 5.0 MHz transducer. The thickness and intensity of the coccygeus muscle were measured and analyzed by gestational status and postpartum to show the differences. Results: The results showed that the thickness of coccygeus muscle increased with the increase in gestational age. Muscle intensity only increased at young gestational age. However, it decreased with the increase in gestational age (P < 0.05). Conclusions: The ultrasound image of coccygeus muscle was affected by gestational status, thus this method may be used as one of the new methods of indirect gestational detection on dairy cows.

The study was conducted to investigate the effects on environmental factors on the reproductive performance of Korean native cattle based on the data from 13, 588 records which were surveyed from 1983 to 1992. The results obtained in this study are as follows; 1. Mean performaces of the reproductive traits were 510.2days for the age at 1st service, 525.0days for the age at 1st conception, 808.7 days for the age at 1st calving, 102.5 days for the days to 1st conception postpartum and 388.6 days of the calving inverval. The cows of Chunbuk province were tended to be bred and calved at younger age and showed shorter calving interval than those of other provinces. 2. The effect of birth year was significant for the reproductive performances, especially, in 1986~1987 when the cattle prices dropped sharply and reproductive performances were poor. 3. The times of 1st service and 1st conception of heifers calved in spring tended to be delayed. Days to 1st conception postpartum, calving interval and days to 1st service postpartum of cows calved in fall were shorter than other calving season's cows. 4. Days to 1st conception postpartum, calving interval and days to 1st service postpartum of cow's were shortened and gestation length was prolonged as the number of parity increases.

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.

Improving the reproductive traits of Hanwoo might decrease their production cost. Therefore, this study was conducted to investigate the effects of environmental factors [registration grade (basic, pedigree or advanced), birth year, birth season, parity, delivery year, and delivery season] on various reproductive traits (age at 1st service, age at 1st conception, age for 1st calving, days at 1st service postpartum, non-pregnant condition period, calving interval, gestation length, and number of services for conception) in Hanwoo (primiparous 12,219 heads, multiparous 10,471 heads). All data was acquired from Gyeongnam province areas which were surveyed from 2007 to 2015. All environmental factors significantly influenced (p < 0.01) reproductive traits of primiparous cows but, but not all environmental factors influenced multiparous cows. Primiparous cows registered as advanced grade showed significantly lower age at 1st service (by 15.36 days), age at 1st conception (by 8.66 days), and age for 1st calving (by 8.77 days) (p < 0.01) than those registered as basic grades. Age at 1st service, age at 1st conception and age for 1st calving were not significantly related to birth year in primiparous cows. As delivery years advanced from 2005 to 2012, all durations associated to reproductive traits tended to be shorter. Days at 1st service postpartum, non-pregnant condition period, and calving interval tended to be shortened as parity increased. Days at 1st service postpartum, days open, calving interval, and gestation in multiparous cows calved in winter were shorter than those in summer. The registration grade was not a effected with reproductive traits in Hanwoo.

Objectives: This study was designed to investigate the effect of delivery nursing care using essential oils on labor stress response, labor anxiety and postpartum status anxiety for primipara. Methods: This study used nonequivalent control group pretest-posttest design. The subjects of this experiment consisted of forty eight primipara with single gestation, full term, & uncomplicated pregnancies. Twenty four primipra were in the experimental and control group each. Their mean age was 27.9 years old, their mean gestation period 279.9 days. As a treatment, delivery nursing care using essential oils was applied by nurses. Data collected epinephrine, norepinephrine, anxiety during labor. In the 24 hours after birth, the data for the postpartum mother's status anxiety was collected. Data was analyzed by t-test, repeated measures ANOVA, Mann-Whitney U test, & Wilcoxon signed ranks test with SPSS Program. Results : Plasma epinephrine, norepinephrine were significantly low in the experimental group (P=0.001, P=0.033, respectively). There was no significant difference between the two groups in anxiety during labor and postpartum mother's status anxiety. Conclusion : These findings indicate that delivery nursing care using essential oils could be effective in decreasing plasma epinephrine, norepinephrine. But, that could not be verified in decreasing mother's anxiety.

Objective : The aim of this study is to investigate rota virus infection of neonates In the Postpartum care center. Methods : This clinical study was carried out with the 205 neonates who admitted to the Postpartum Care Center of ${\bigcirc}{\bigcirc}$ Oriental Medicine Hospital, from July, 2004 to July, 2005. Stools were examined daily with Rotazyme ELISA tests(Bio Line Rota Virus, SD Standard Diagnostics, INC.) for 3 days from the day of admission. Supplementary test was examined when change was found in stools. Results : Among 205 newborn babies, 58 cases turned out to be positive. The positive rate of rota virus was not significantly related to sex, birth weight, gestation age. But, it was significantly related to delivery method and it was higher in caesarean section group. The manifestation rates of symptoms were 51.7% in Rotazyme positive neonates. In the Rotazyme positive 58 cases, 30 cases(51.7%) had diarrhea, 8 cases had fever(13.8%), 1 case(1.7%) had vomiting. The positive rate of rota virus was higher during from october to march. There were 190 cases(92.2%) of mixed feeding and 15 cases(7.8%) of artificial feeding. There was significance between breast feeding and the positive rate of rota virus. There was no significance between hospital of birth and the rate of positive rotazyme test. Conclusions : A further study of neonates in postpartum care center is necessary as preference of postpartum care center was increased. And the oriental medicine treatment of rota virus IS expected to be effective, so a further study is necessary.

This study was conducted to estimate the effects of environmental factors on certain reproductive traits in Korean cattle on the basis of data from Korean Cattle Improvement Areas which were surveyed from 1986 to 1995. Results obtained were summarized as follows ; 1. Least square means of the reproductive traits estimated were 466.11${\pm}$5.72 days for age at 1st service, 480.10${\pm}$6.15 days for age at 1st conception, 742.79${\pm}$7.48 days for age at 1st calving, 64.97${\pm}$1.42 days for days at 1st service postpartum, 72.06${\pm}$1.73 days for days open, 355.93${\pm}$1.92days for calving interval, 285.38${\pm}$0.42 days for gestation length and 1.21${\pm}$0.02 days for number of services for conception, respectively. 2. The ranges of the least squares means for the districts were 447.62${\pm}$5.94-490.72${\pm}$5.94 days for age at 1st service, 464.27${\pm}$6.38-505.20${\pm}$6.39 days for age at 1st conception, 721.91${\pm}$7.85-772.75${\pm}$7.80 days for age at 1st calving, 62.27${\pm}$1.55-68.97${\pm}$1.74days for days at 1st service postpartum, 69.74${\pm}$1.97-74.36${\pm}$2.27days for days open, 352.71${\pm}$2.18-359.64${\pm}$2.09 days for calving interval, 284.52${\pm}$0.42-286.04${\pm}$0.47days for gestation length and 1.11${\pm}$0.02-1.30${\pm}$0.02 days for number of services for conception, respectively. 3. Age at 1st service was latest in the cows with Basic Register and tended to be earlier for the more advanced registers. The number of services per conception tended to increase for the more advanced registers. 4. Days at 1st service postpartum was longest in the 2nd parity and tended to be shorter with the advancement of parity. The number of services per conception tended to decrease with the advancement of parity. 5. As the calving year advances from 1987 to 1995, days at 1st service postpartum, days open and calving interval tended to be longer, and number of service per conception tended to increase. 6. Days at 1st service postpartum, days open and calving interval were shorter in the cows that calved in spring and summer than in the cows that calved in fall and winter. The number of services per conception was larger in the cows that cocalved in fall and winter than the cows that calved in spring and summer.

Purpose: This study was done to test the effects of Oketani breast massage on breast pain and breast milk pH of mothers, and sucking speed of neonates. Methods: A nonequivalent control group and a pretest-posttest design was used. Postpartum mothers complaining of breast pain were recruited at a postpartum care center. The application of Oketani breast massage by an Oketani massage therapist was the experimental treatment. The control group received the conventional massage technique from a nurse at the postpartum care centre. The collected data were analysed using a $x^2$-test and a t-test with the SPSS WIN 12.0 program. Results: The participants were homogeneous in age, gestation period, and birth weight. Breast pain (t=8.384, p<.001) was significantly relieved, and breast milk pH (t=4.793, p<.001) was significantly increased in the experimental group compared to the control group. The sucking speed of the neonates in the experimental group was significantly increased compared to the control group (t=9.920, p<.001). Conclusion: These findings indicate that Oketani breast massage is effective in relieving breast pain and increasing breast milk pH as well as the sucking speed of neonates.

Changes in total lipid content, total cholesterol content and fatty acid composition of preterm milk were investigated during early lactation. Milk samples were collected from Korean mothers of 16 premature(34 to 36 weeks gestation age) infants on day 2 to 5(colostrum) and at 6 weeks(mature) postpartum. We estimated the lipid nutrition of preterm milk by comparing with the lipids of term milk. The total lipid content of preterm colostrum was significantly lower than the lipid content of preterm mature milk(p<0.001). Lipid content, determined gravimetrically in colostrum and matured milk, was 1.50g/이 and 3.2g/dl, respectively. Also the total cholesterol content(mg/dl) in preterm milk tends to increase from 14.16mg/dl to 15.20mg/dl, while the total cholesterol(mg/g lipid) concentration higher significantly in colostrum(12.36mg/g) than in mature(5.73mg/g)(p<0.001). The total unsaturated fatty acid contents in preterm milk were higher in colostrum than in mature milk and the total saturated fatty acids were higher in mature milk. The average DHA contents of colostrum and matured milk was 0.64%, 0.53% and the P/M/S ratio of preterm milk were 0.63 : 1.05 : 1.00, 0.47 : 0.79 : 1.00, respectively. Also, $\omega$6/$\omega$3 ratio of preterm milk were 2.35 in colostrum and 5.81 in mature. Therefore, colostrum in preterm milk contained higher amounts of $\omega$3 PUFA than mature milk. The levels of total lipid in preterm milk were higher than term milk. Also, preterm milk is richer in cholesterol, and long chain polyunsaturated fatty acid than term. It appears that the milk secreted by mothers who delivered prematurely differs from milk in several important respect. These components may serve as precursors for membrane, myelin development in the preterm infants. Therefore, it would be necessary to study further into the machanism of how the gestation age might affect to the lipid composition in human milk. These data may provide a basis for better construction of infant formaulas to provide more adequately for the lipid requirements of the Korean premature infant.
