The natural growth rate of the Korean population has decreased from 3.0% in 1960 to 1.0% in 1990. This was done with family planning program which was introduced by the government in 1961. The family planning program focused on birth control rather than the characteristics of the individuals and motivations of contraception. People were simply forced to use the method. Whereas, Natural Contraceptive is a method of family planning based solely on the timing of intercourse with the naturally occurring' physiological manifestation of fertilization and in fertilization during the menstrual cycle. This is the combination of self fertility awareness with periodic abstinence. Natural family .planning(NFP) programs in Korea were first started in the Chun-Chen diocese of catholic church by Bishop Thomas Stewart in 1970 In 1975, the Bishops conference launched the Korea Happy Family Movement in the Catholic Hospital Association, to promote the natural family planning. An average of 70,000 people, including adolescents, college students, unmarried and married persons, arid the clergies were trained during a six-year period (1986-1991). 61.5%(24,542 people) of those who completed 3 cycles during 6 year period (1986-1991) became autonomous users and the range was from 48.1% to 78.2%. In 1986, 22.7% of NFP individuals who drooped out of the program because of the desire for conception (23.4%), the difficulty of the method used(25.8%), and the loss of interest(22.8%). During the six-year period the unplanned pregnancy rate at the NFP was 2.9%. The range of the pregnancy rate was at 1.2-9.8%. The rate was decreased as years passed. The major reason for the failure of contraceptive was error by the individuals(61.1%). The percentage of the success of conception was 18.1% of 2.979 for achieving pregnancy. The highest percentage was 58.2% (99 users) in Kwang-Joo diocese and next was 37.1% (10 users) in Chong Joo diocese.

Tremendous progress has been made over the past quarter-century studying the genetics of gametogenesis and the resulting gametes and embryos. Studies merging molecular techniques and conventional cytogenetics are now beginning to bridge the gap between what we have learned about the meiotic process in males and females and what we know of the mitotic chromosomes of zygotes. Numerical abnormalities in sperm, oocytes and embryo can now diagnosed by fluorescence in situ hybridization (FISH). "At risk" couples can, therefore, have only unaffected embryos replaced in the sterus and avoid the possibility of terminating a pregnancy that might only be diagnosed as affected later gestation. Single-cell genetic analysis has also provided powerful tools for studying genetic defects arising during early human development. Recent studies of sperms, oocytes and cleavage-stage human embryos have revealed an unexpectedly high incidence. These genetic abnormalities are likely to contribute to early pregnancy loss and have important implications for improving pregnancy rates in infertile couples by assisted reproduction. The widespread use of preimplantation genetic diagnosis (PGD) awaits further documentatio of safety and accuracy. Other issues also must be addressed. First, the ethical issues regarding germ cell and embryo screening must be addressed including what diseases are serious enough to warrant the procedure. Another concern is the use of this technology for non-genetic disorders such as gender selection. Finally, the experimental nature of these procedure must continually be discussed with patients, and long-term follow-up studies must be undertaken. Development of more accurate and less expensive assays coupled with improved assisted reproductive technology success rates may make PGD a more widely use clinical tool. The future awaits these development.velopment.

The present study was conducted to investigate the effects of Korean red ginseng water extract (KRGWE) on developmental toxicity caused by the environmental estrogen bisphenol A (BPA) in Sprague-Dawley rats. fifty males successfully mated were randomly assigned to five experimental groups, 1.e., group I (vehicle control), group II (BPA 1000mg/kg), group III (KRGWE 400mg/kg), group IV (BPA 1000mg/kg & KRGWE 200mg/kg), and group V (BPA 1000mg/kg & KRGWE 400mg/kg). The test articles were administered by gavage to mated females from gestational days (GD) 1 through 20 (sperm vaginal lavage=day O). All females were subjected to caesarean section on GD 21 and their fetuses were examined for external, visceral, and skeletal abnormalities. In the group II, significant maternal toxic effects including suppressed body weight, decreased body weight gain during pregnancy, and reduced food consumption were observed in pregnant rats. The minimal developmental toxicity including fetal ossification delay was also found in fetuses. In addition, a tendency for increased pregnancy failure, increased pre-and postimplantation loss, and decreased fetal body weight was observed. However, no fetal morpho-logical abnormalities were seen in surviving fetuses at a dose level of 1000mg BPA/kg. On the other hand, the maternal toxicity and developmental toxicity found in the groups IV and V were comparable to those of the group II. There were no adverse signs of either maternal toxicity or developmental toxicity in the group III. These results showed that administration of BPA at a dose level of 1000mg/kg to pregnant rats resulted in significant maternal toxicity and minimal developmental toxicity, and that no protective effects on BPA-induced maternal toxicity and developmental toxicity were found by concomitant gavage dosing of KRGWE.

This study was carried out through the investigation of Oriental and Western medical literature and we was discovered these conclusions about the etiology, treatment, prescription of habitual abortion. The result of this study were as follows : 1. The habitual abortion does agree with 'Hwaltae(滑胎)' and means that spontaneous abortion repeats three times or more. 2. The etiology of habitual abortion is divided 'Deficiency of kidney'(腎虛), 'Deficiency of vital energy and blood'(氣血虛弱), 'Deficiency of yin'(陰虛), 'Clotted blood'(瘀血). 3. By means of cause, the treatment of habitual abortion was mainly made use of 'Tonifying kidney and promoting spleen'(補腎健脾), 'Invigorating vital energy and nourishing blood'(補氣補血), 'Supplementing yin fluid and alleviating fever'(滋陰淸熱), 'Resuscitating blood and removing clotted blood'(活血祛瘀). 4. By means of cause, the prescription of habitual abortion was frequent made use of Bosingochunghwan(補腎固沖丸), Bosingotae$\breve{u}$m(補腎固胎飮), Taesanbans$\breve{o}$ksan(泰山磐石散), $Ch\breve{o}ng\breve{u}mboinghwan$(千金保孕丸), Agyotang(阿膠湯), Gungguibojungtang(芎歸補中湯), Taewon$\breve{u}$m(胎元飮), Gotaej$\breve{o}$n(固胎煎), Baekchulj$\breve{o}$n(白朮煎), Sas$\breve{o}$ngsan(四聖散), Gyegibokryonghwan(桂枝茯苓丸), $Dangguich\breve{o}ng\breve{u}mtang$(當歸千金湯). 5. The Western medical etiology of habitual abortion(recurrent spontaneous early pregnancy loss) is divided Genetic factor(Chromosome aberration), Anatomical deformity, Endocrinologic disorder, Infection, Immunologic factor, Unknown factor(Others).

The process of breast feeding was investigated from the 36th week of pregnancy to 12 weeks postnatal, in order to analyze the factors affecting breast feeding duration and provide the basic data on an education program for successful breast feeding. The general characteristics of study group had no marked effects on the breastfeeding duration. The young and highly condition during pregnancy and the degree of morning sickness affected the practice of breastfeeding. In the study of prenatal sociobehavioral factors, intended duration affected the breastfeeding duration, and the maternal perception that breastfeeding is good for weight loss after delivery as well as infant formula milk is not as good as breast milk, led to successful breast feeding. Among the postnatal biological factors, the duration of gestation affected the breast feeding. Among the postnatal biological factors, the duration of gestation affected the breastiffeding outcome. In the case of early parturition, breastfeeding rate was low. Among the postnatal biocultural factors, time of first feed, milk volume and maternal perception of infant's sucking ability affected the bresatfeeding duration. From these result, it is suggested that an education program such as participation of nursing class to the pregnant women should be provided for successful breastfeeding.

Here, we report isolation of multiple long non-coding RNAs (lncRNAs) expressed tissue-specifically during murine embryogenesis. One of these, subsequently came to be known as Redrum, is expressed in erythropoietic cells in fetal liver and adult bone marrow. Redrum transcription is also detected during pregnancy in the spleen where extramedullary hematopoiesis takes place. In order to examine the function of Redrum in vivo, we generated a gene-targeted murine model and analyzed its embryonic and adult erythropoiesis. The homozygous mutant embryo showed no apparent deficiency or defect in erythropoiesis. Adult erythropoiesis in bone marrow and in the spleen during pregnancy likewise showed no detectable phenotype as red blood cells matured in normal fashion. The phenotype is in contrast to the reported function of Redrum in vitro, and our observation implies that Redrum plays in vivo an accessory or supplementary role whose loss is compatible with normal erythropoiesis.

목 적：10대 임신의 보다 정확한 역학적 접근을 위한 일련의 연구의 첫 단계로, 우선 의료 일선에서 10대 산모를 돌보고 있는 산부인과 전문의들을 대상으로 하여, 이들이 현장에서 인지하고 있는 10대 임신의 현황과 문제점 및 정신과 자문에 대해 파악코자 본 연구를 시행하였다. 방 법：10대 임신의 빈도, 특성, 출산과 중절의 결정과정, 산모 및 신생아의 산부인과적, 정신과적 문제점, 정신과 자문 필요성을 중심으로 한 구조화된 설문지를 작성하여 전국 2800명의 산부인과 전문의에게 우편으로 배포한 후 회수된 349명의 자료를 분석하였다. 결 과：(1) 10대 임신의 빈도는 약간 증가한다는 추세였으며, 10대 임신모가 처음 병원을 방문하는 시기는 임신초기와 중기가 가장 많았으며, (2) 임신의 원인으로는 강압적이나 난잡한 성 관계보다는 지속적인 성 관계 에 의한 우발적 임신이 가장 많았다. (3) 출산하게 된 원인은 임신중절시기를 놓쳐서가 가장 많았다. (4) 10대 임신모의 정신심리학적 문제로는 지능저하나 성폭행피해 보다는 성 지식의 부재나 비행소녀가 많았다. (5) 10대 임신모에 대한 상담 역할은 대부분 산부인과 의사 본인이 담당하였고 정신과전문의나 전문 상담인력과 연계하는 일은 비교적 드물었다. 대부분 정신과 자문의뢰 필요성은 느끼나 ‘보호자나 환자의 거부’때문에 현실적으로 어렵다고 하였다. (6) 10대 임신에 관한 가장 절실한 예방대책으로는 피임교육이라고 응답하였다. 결 론：본 연구의 결과를 토대로 추후 10대 임신모를 대상으로 한 체계화된 면담기법을 이용하여, 10대임신의 위험요인을 분명히 하고, 이들의 사회적응에 관련된 정신과적인 접근방안과 나아가 10대 임신의 예방방안에 관한 구체적인 연구가 산과의사와 연계하에 이루어져야 되리라 본다.고 지능 수치가 상대적으로 낮아 학습 및 학교 생활 적응에 어려움이 더 많을 것이므로 적극적인 치료개입이 필요할 것으로 생각되었다.모두 능력의 향상을 보였으나, 간섭이 있는 주의력 검사에서는 산소흡입군만이 유의한 호전을 보였다. 또한 처치 전후의 변화율((치료후값-치료전값)/치료전값 *100)을 계산하여, 산소군과 공기군 간의 통계적 유의성을 평가한 결과, 공기 흡입군에 비해 산소흡입군이 스트룹 검사의 간섭시행, 그리고, 선로잇기검사의 B부분의 수행에서 유의한 차이를 보여, 산소흡입이 전두엽의 수행능력과 관련된 주의력의 호전에 보다 유의한 기여를 할 가능성이 있음을 보여주었다. 2) 기억능력평가：16가지의 기억능력 평가 도구 소척도값 중에서, 산소흡입군은 흡입 전에 비해 11개의 소검사 항목들에서 보다 우수한 수행을 보여 주었고, 공기흡입군은 7개 영역에서 유의한 호전이 있었다. 처치전후의 각 소척도 값의 변화율을 계산하여, 산소군과 공기군 간의 통계적 유의성을 평가한 결과, 단기기억소척도의 점수에서만, 두 군간에 유의한 통계적 차이가 발견되었다. 결 론：주의력과 기억능력에 미치는 산소효과를 검증하기 위해, 대조군비교-이중맹검 임상실험을 실시하여, 반복검사로 인한 효과, 위약효과 등을 배제하였다. 그 결과 양쪽 검사 모두에서 어느 정도의 반복검사 및 위약효과가 확인되었으나, 주의력에서는 전두엽의 실행능력(executive function)과 관련되는 검사들에서 산소흡입이 특이한 효과를 보여준다는 것이 확인되었고, 기억능력에서는 단기기억능력 평가에서 산소흡입군이 대조군보다 유의한 효과를 보여주는 것으로 평가되었다. 이러한 연구결과는 산소흡입이 전두엽과 관련된 수행능력, 작동기억능력 향상에 도움이 될 가능성이 있음을 시사하는 결과라고 생각된다.증 1명(5%)이었다.

Cytomegalovirus (CMV) is currently the most common agent of congenital infection and the leading infectious cause of brain damage and hearing loss in children. Symptomatic congenital CMV infections usually result from maternal primary infection during early pregnancy. One half of symptomatic infants have cytomegalic inclusion disease (CID), which is characterized by involvement of multiple organs, in particular, the reticuloendothelial and central nervous system (CNS). Moreover, such involvement may or may not include ocular and auditory damage. Approximately 90% of infants with congenital infection are asymptomatic at birth. Preterm infants with perinatal CMV infection can have symptomatic diseases such as pneumonia, hepatitis, and thrombocytopenia. Microcephaly and abnormal neuroradiologic imaging are associated with a poor prognosis. Hearing loss may occur in both symptomatic and asymptomatic infants with congenital infection and may progress through childhood. Congenital infection is defined by the isolation of CMV from infants within the first 3 weeks of life. Ganciclovir therapy can be considered for infants with symptomatic congenital CMV infection involving the CNS. Pregnant women of seronegative state should be counseled on the importance of good hand washing and other control measures to prevent CMV infection. Heat treatment of infected breast milk at $72{^{\circ}C}$ for 5 seconds can eliminate CMV completely.

Objectives: Hyperemesis gravidarum (HG) is defined as severe nausea and vomiting during pregnancy (NVP) with weight loss, ketonuria, and electrolyte imbalance. Many NVP or HG patients get hard to take herbal medicine since the smell and taste of it. Therefore, the distilled herbal medicines are often used in clinical practice. A 32-year-old, 14-week pregnant female was admitted for 3 weeks at a Korean medicine hospital. She was experiencing HG accompanied by 19.61% (10 kg) weight loss, ketonuria, and electrolyte imbalance. The patient received Bosaeng-tang gagambang in its distilled form, acupuncture, electro-acupuncture, sticker needles, cupping, moxibustion, and hydration during admission. The severity and frequency of NVP, weight loss, and ketonuria significantly improved without any side effects. Before the therapy, she admitted to two obstetrics and gynecology hospitals, 1 week each, with no improvement. This case presents the therapeutic potential of Korean medicine including herbal medicine in its diluted form for HG and NVP.

Recently in Korea, integration of F.P. & MCH programs for effective and efficient implementation of the health programs has been discussed actively. In fact, categorical health workers in fields have been trained and changed as an integrated health workers by government. But one of the most important problems that had to be solved for successful integration of F.P. and MCH programs, is that there must be a common indicator for the evaluation of the two health services (integrated indicator). We regarded reproductive efficiency (=R.E.) that had been proposed by Charlotter M$\ddot{u}$ller et al, as the good integrated indicator. The object of this brief article is to introduce the meaning of reproductive efficiency and to illustrate the usefulnesses of R.E. as the integrated health indicator by applying this indicator to the data from preliminary survey of Seosan demonstration project for integration of F.P. & MCH service supported by WHO. The results and conclusions are as follows 1) Definition of R.E. is the percentage of pregnancies that succeed in production normal, surving children after taking into account the frequency of all measurable types of adverse outcomes (End point for evaluation of survival is one year of age). 2) On the basis of the past pregnant history, reproductive efficiency of the 2,484 eligible women (15-44 years) was roughly 75% (But, in the concept of good births, it is not regarded whether the survived infant is normal health or not). 3) Compared with the results of the other two surveys of the rural area in Korea, reproductive efficiency has been slightly decreased than before, in spite of family planning and MCH services for past 20 years. Because the quantity of increased abortion rate overwhelmed that of the decreased infant mortality rate. 4) Reproductive efficiency has the object for measure many events during the period from the conception (Wanted pregnancy) to an normal surviving children as an 1 year of age. So these heterogenous adversities, ie, induced abortion, still births, spontaneous abortion, neonate & infant death, are aggregated as R.E. However, if the information of these important events and reproductive efficiency were given, R.E. is used as the comprehensive evaluation indicator for F.P. and M.C.H. after meticulous analysis the various components of R.E. 5) Economic loss for adverse outcomes of preg were pregnancy were calculated applying the medical cost at the relatively small sized hospital of small city. Economic loss for 100 cases of adverse outcome is 10,420,000 won, and economic loss for infant death is 46.1% of the total loss. So, it is rational to invest much more effort and than before to MCH programs.
