This study aims to prevent maternal social isolation by analyzing the causes of postpartum obesity and postpartum depression and stress in Korea. Gneral characteristics of mothers as a result of the study: 91.1% (102 people) answered that they had social experience, and only 8% (9 people) answered that they had no social experience. In the question of whether to return to society, 17.9% responded that they have already returned, 54.5% did not, and 18.8% were on maternity leave. As a result of examining the level of BMI increase among mothers through chi-square test of BMI changes before and after childbirth and general characteristics, 55% experienced below-average BMI increase; 45% experienced above-average BMI increase. Those in their 30s accounted for 40.2%, and those in their 40s accounted for 57.1%. Postpartum obesity and maternal psychological status (t-test): Mothers with postpartum obesity were more hypersensitive (t = -1.997, p = 0.048) and more prone to suffer from hard breathing (t = -1.930, p = 0.056), emptiness (t = -2.673, p = 0.010), and body numbness (t = -2.315, p = 0.024) than mothers who are not suffering from not postpartum obesity. Per the results of postpartum BMI increase and maternal psychological state (t-test) analysis, mothers with an average increase in postpartum BMI were more depressed than mothers who did not. Research Results - Postpartum obesity due to pregnancy and childbirth has been identified as an important individual cause affecting mental and physical problems after childbirth. In conclusion, I also think that the government should support the management of maternal obesity and the elimination of depression through the results of this study.

This study was conducted to research the endocrine mechanisms of postpartum anestrus and determine if the morphology of the CL could be related to function in Korean native goats. At parturition 48 goats were assigned to a nonsuckled group and a suckled group. Serum concentrations of luteinizing hormone(LH), follicle stimulating hormone(FSH), prolactin(PRL), estradiol-17$\beta$(E2) and cortisol were measured at various times after parturitionin the goats. The corpora lutea of pregnancy were examined by a light microscope on the 6th hour and the first, 3rd, 10th, 11th, and 21st days after parturition. The results were summarized as follows : Mean serum LH concentrations were lower after parturition in all treatments and increased gradually with the intervals after parturition(P<0.01). These values did not differ between groups. The levels of serum FSH were lower after parturition and tended to increase gradually between 2 and 21 days. The levels of serum FSH are not significantly different between the groups of goats. Two days after kidding mean levels of serum PRL began to fall in nonsuckling goats but increased in suckling goats. During 3 weeks serum PRL concentrations were different between nonsuckling and suckling goats(P<0.01). Three days after parturition the levels of serum E2 decreased in all treatments. From parturition to day 21 serum E2 concentrations were greater in nonsuckling than in suckling goats(P<0.01). At the sixth hour after parturition the structure of the CL was well preserved. At days 1 and 3 the blood vessels were sparcely distributed, whereas, at days 1 and 3 the blood vessels were sparcely distributed, whereas, at days 10, 11 and 21 tortuous larger vessels with thick walls were observed on the luteal tissue. At days 1, 3, 10, 11 and 21 after parturition the CL of pregnancy showed degeneration and the proportion of tissue occupied by intercelluar substances increased at days 21 postpartum. In conclusion, the present study has shown that regression of the CL of pregnancy is accelerated in the period after parturition and effectively completed within three weeks postpartum.

Authors surveyed intrafamilial child sexual abuse in the children under 15years old in clinical. We sent the semi-structured child sexual abuse questionnaires to 7055 board certified pediatrics, obstetrics and gynecology, family medicine and emergency medicine. Total respondents were 1205. The results from these respondents were as follows. 1) The numbers of respondents who have had the experience of treating victims of intrafamilial child sexual abuses were 157(13.0% of total respondents). 2) Among the perpetrators, 58(36.9%) were siblings and 32(20.4%) 26(16.6%) were step-fathers, and respectively. The most common age bracket was 10s(39.5%), and the next was 40s and 50s (33.7%) Almost all(98.7%) of the perpetrators were male. 3) The mean age of victims was $12.1{\pm}3.3$ years old, and all of the victims were female, and the number of victims who had previous mental or physical handicaps and behavior problems were 5(3.2%) and 8(5.1%) respectively. 4) The ways by which intrafamilial child sexual abuses were found were abnormal behaviors 45(28.7%), victim's own report 40(25.5%), pregnancy 18(11.5%), pain complaint 13(8.3%), other person's report 13(8.3%), and detection during examination 12(7.6%). 5) Time lags between intrafamilial child sexual abuses and hospital visits were after 1 month 97(61.8%), from 1 day to 1 week 29(18.5%), within 1 day 21(13.4%), and from 1 week to 1 month 10(6.4%). 6) Physical complications were perineal wound 93(59.2%), hymen rupture 90(57.3%), pregnancy 68(43.3%), wound of other part of body 11(7.0%), and sexually transmitted disease 4(4.5%). 7) Treatment for victims were discharge 92(58.6%), admission, operation or transfer to a bigger hospital 25(15.9%), psychiatry consult 19(12.1%), report to police(10.9%) and social work consult 3(1.9%). These results suggest that considerable numbers of physicians have had the experience of treating victims of intrafamilial child sexual abuses, and intrafamilial child sexual abuses are the major medical as well as social issue in children in Korea.

Developmental dysplasia of the hip broadly includes inadequate development of the hip joint involving the acetabulum or proximal femur, or both. Although ultrasonographic studies in neonates have greatly lowered the frequency of neglected or operatively treated cases, its sensitivity is less than desired. Hip dysplasia without subluxation is commonly diagnosed incidentally and strongly related to degenerative arthritis in females after the 4th decade. Hip dysplasia with subluxation shows symptoms through various periods, depending on its severity, especially for women with onset during pregnancy. A complete physical examination and early treatment for neonates are extremely important for obtaining satisfactory outcomes. To avoid underdiagnosis and to serve appropriate treatment on time, the authors recommend examining any suspicious hips in infants under two years of age. The study will discuss the diagnosis and primary treatment of developmental dysplasia of the hip.

This experiments was carried out to evaluate the effect of nitrogen retention on different levels of crude protein intake according to live weight, and the crude protein and urea content in serum of the Korean native goat. The results obtained are as follows: 1. When the female goat at 8 months age (14kg) had taken nitrogen free diet, the content of endogenous urinary nitrogen was 1.29g and endogenous fecal nitrogen was 1.27g per day. Therefore, the goat needs minimum level of crude protein per day. 2. When the thermometer checked below-$10^{\circ}C$, the nitrogen retention rate showed minus reaction in spite of 20% crude protein level. This suggested that the low temperature was consumed higher energy to maintain the body. 3. The nitrogen retention rate of the pregnant female goat of 20kg live weight, however, decreased as compared with the growing goat and was 17~20%. 4. According to the levels of crude protein were lower, crude protein and urinary nitrogen contents in serum were greatly decreased.

This study was conducted to identify characteristics observed by staff during infertility treatment, and to analyze the relationship between the result of the treatment according to the ART infertility characteristics. In cooperation with an Obstetrics and Gynecology Hospital in Ulsan, data were collected from 344 people receiving infertility treatment from 2012-1013 and evaluated by cross-analysis, logistic regression analysis, and the ${\chi}^2$ test. Age 30 subjects (72.1%), no disease (70.9%), and no birth children (77.0%) were most common among patients. Causes of infertility factor is the higher the age, followed by uterine factors, ovarian factors were the lower the age.Were assisted reproduction are IUI (51.5%), IVF (23.0%), IUI + IVF (25.6%), assisted reproduction were age (p<.013) infertility period (p<.014), abortion Experience (p<.008) it was not statistically significant. ART pregnancies result was 34.9%, IUI was 49.2%, IVF was 50.8%. The average number of successful IVF treatment was 1.64, while it was 1.36 for IVF. IVF is 0.28 times lower than the IUI. Thus, low in order to increase the success rate of pregnancy according to the assisted reproduction age, nanim period is short, and if you do not have birth children choose artificial fertilization, and high age, IVF If there are nanim period is longer and birth child treatment and you must choose. This study analyzed all subjects who underwent fertility treatment to have research significance. However, it is difficult to generalize, locally called Sun City limits. If this one based on regional and national follow-up study of infertility therapist made it will help to prepare the way of effective treatment for infertility causes.

The aim of this study was to investigate the effects of dietary supplementation of pelleted-Italian Ryegrass (IRG) as a source of fiber on reproduction performance in pregnant sows. A total of 24 pregnant sows were randomly assigned to four dietary treatments, which was given a corn-soybean diet with 0%, 10%, 20%, and 30% pelleted-IRG from 105 days prepartum to 7 days postpartum. During experimental period, the sows fed the IRG supplemented diet showed the lower feed intake than the sows fed the control diet (p<0.05). The changes of body weight in sows from initial to pre- and/or post-partum was significantly smaller in sows fed the IRG supplemented diet than control group. It is thought that the lower weight gain in IRG supplemented groups is caused by low feed intake. Although there was no significant difference, sows fed the IRG supplemented diet tended to increase the litter size and birth weight in piglets compared with sows fed the control diet. This result suggests that the dietary supplementation of IRG has the positive effects to improve the reproductive performance in sows. But, the excessive feeding of IRG to sows might cause to retard the days of return to estrus, and decrease the contents of solid, milk protein, and milk fat in colostrum. Thus, the addition of about 10% IRG is desirable to increase the reproductive performance. Meanwhile, the feeding energy diet is better effective than feeding the fiber diets to improve overall productivity in sows after postpartum.

To obtain some results of the rate of abnormal keton body in urin of dairy animals by age calving rate, milk yield and some feeding and management condition, 104 cows and 107 dairy goats were investigated. And the results obtained were summerized as follows. 1. From about 23.1% of cows and 39.3% goats, abonormal condition of keton body in urine dectated. 2. The rate of abnormal keton bodies possession were lower at the age of 1~4 but higher at the age of 4~11. 3. From the calving animals, the highest rate of keton body were detected but the lowest from first and ninths calving animals. 4. The cows than 20kg milking per day and the goats 3~4kg milking were higher but the cows below 10kg milking and the goods 1~2kg milking were lower. 5. Under bad feeding and management condition, the amount keton bodies in urine of animals were increased much.

Purpose : The purpose of this study was to identify factors influencing premature infants who are small for their gestational ago. Methods : The medical records of 1,010 premature infants of 26 to 35 weeks of gestational age born at Il-Sin Christian Hospital, Busan from January 2000 to August 2006 were reviewed. We collected data on gestational age, birth weight, infant gender, birth order, maternal age and previous abortion history and analyzed the factors influencing premature infants who were small for their gestational ago at birth. Results : In our study more female than male (P=0.042) in premature infants who were small for their gestational ago were born from mothers aged younger than 20 or older than 35 (P=0.041). But association between smallness for gestational age and birth order or maternal previous abortion history was statistically insignificant (P=0.228, P=0.129). Conclusion : Considering the association of birth weight and the survival rate of premature infants, it is thought that maternal age had an influence on the survival rate of premature infants. Social and political support to lower the teenager pregnancy and older pregnancy is expected to increase the survival rate of premature infants and the birth of healthy normal neonates.
