  • Over one million cases of the induced abortion have been conducted annually in Korea. Among those cases, most of all were illegally done, but this has not been addressed in the literature. While Korean Nurse Association Code of Ethics presents the respect for life as one of the basic ideology, it was not dealt enough in nursing education. The purposes of the study were to activate the debate on the issues related to an induced abortion ; to introduce the related ethical theories ; and to seek the solution of the ethical problems, which will eventually result in establishing the morality of nursing practice. The ethical theories of an induced abortion have traditionally addressed two extreme perspectives ; the conservatives who emphasize the sanctity of human life and the right of life that will never ethically allow the killing fetus ; and the liberalists who insist the right to choice for women to control their body. Since these extreme theories has not been helpful to solve the ethical problems, the recent trend is leading to the modified theories both from conservative and liberal perspectives. The examples of the theories are the potentiality of fetus(Singer, 1993), the obligation of women to serve their body to fetus(Held, 1987), the Replacement theory (Callahan, 1987), and the Principle of Caring (Gilligan, 1982). The study conducted the indepth interviews with 17 women who experienced the induced abortion and the 6 cases were selected to be analyzed. The cases were analyzed and interpreted by using an integrated case method which was combined of the New Casuisty(Jonsen & Toulmin, 1988 ; Jonsen, 1991) and the Specified Principlism (Richardson, 1990 ; Degrazia, 1992). The result of analysis revealed three types of ethical problems ; (1) the responsibility of taking care of the baby to be born (2) the fear for the condition of the fetus, and (3) the choice of induced abortion as the method of birth control. The findings also revealed the related ethical principles for various situations ; the principle of caring was used for choosing an induced abortion by the subjects ; the principles of the potentiality of fetus and the obligation of women to serve their body were for the consideration for the life of fetus ; and the principle of replacement was utilized for the right to choice for women. The ethical principles related to an induced abortion introduced in the study provided the way to solve the moral problems by applying to the clinical situations for nurses. The study also revealed the possibility of modifying the current ethical theories from the method of applying the principles to the various situation in the study. The modified theories would be more useful to guide the clinical practice with similar ethical problems.

  • Placenta accrete patients whose mother mortality rates are rather high due to massive bleeding during childbirth need to have Prophylactic placement of Internal Iliac Artery Balloon Occlusion Catheters procedure to reduce amount of blood loss and inoperative transfusion. Nevertheless, studies for mothers inevitably exposed to dose during PIIABOCs procedure have not been published many yet. Therefore, this study is to investigate exact information on radiation dose exposed to fetus during PIIABOCs procedure. Average effective dose of fetus per organ is 2.38~8.83 mGy, measured highest at beam center and followed by eyeball, stomach and bladder. The result showed that the longer fluoroscopy time is used, the closer beam center is and the thicker abdominal thickness is, the more effective dose on fetus is increasing. When using the collimator and protection shown to decrease the effective dose and when using higher the patient table shown to decrease the effective dose. It has been reported that the threshold of deterministic effect is about 100mGy. Deterministic effect was regarded as a factor that would influence on fetus exposed by medical radiation than stochastic effect. Consequently, it concluded that dose exposed on fetus in PIIABOCs procedure was approximately 10% of threshold of deterministic effect with effective dose of 0.49~18.27 mGy.

  • Objectives : 'Taegyo,' prenatal education, is steeped into Korean culture. Although there has been a traditional focus on providing education and care for the fetus in Korea, there is a lack of medical evidence for its effectiveness. Methods : The authors assessed the scientific basis for 'Taegyo' by reviewing the evidences. Results : 'Taegyo' in Korea began with the spread of Buddhist culture from China, and transmitted by word-of-mouth. The first 'Taegyo' book, the Tae-gyo-shin-gi, was published on 1803. Modern prenatal education is very diverse. However, only a few studies on its effect have been conducted. Development of medicine, especially obstetrics, fetology, pediatrics, psychiatry, and etc., has learned that many factors, including bad environmental conditions and maternal stress, influenced against the fetus and mother. As for the paternal side, occupation, smoking, and stress were also revealed to have consequences for the development of the fetus. On the contrary, adequate maternal nutrition, exercise, and music stimulation positively impact the fetal development and healthy birth. Conclusion : Traditional contents of 'Taegyo' were proved to have effectiveness from evidence-based medicine and animal experiments. We need further studies to explore the impact of prenatal education for the fetal development and maternal health.

  • All human health behavior is deeply rooted one's beliefs or value system usually encompassed within the culture in which they live. The Taegyo, based on Oriental folk medicine, is defined as the behavior and self care of pregnant women administered for herself and her fetus(unborn child). Taegyo is believed to be desirable, effective, and healthy behavior by most of Korean pregnant women. It is essential in our contemporary culture, to ascertain what the components of Taegyo are and to integrate them into current, western nursing care, particularly in the area of prenatal care. 910 Korean women were the subjects of this study, who were in a gestation period of pregnancy between 10 weeks to three months postpartum. The subjects were selected by clustered smpling from 10 representative cities in Korea. Data was collected from February 10 to March 30 1995 by a constructed Questionnaire which consisted of 95 items. The questionnaire was developed through three steps such as content analysis, calculation of content validity index, and pretest. Data was analyzed by descriptive statistics and rotated matrix factor analysis with pc-SAS. The mean age of the subjects was 28.9 years : 36.5% of them were employed and the mean income per month was about 2000 dollars. The component of Taegyo was clustered into five factors such as fetus psychological stability(equity), fetus personality development, maternal-fetal interaction, fetus intellectual development and physical health promotion. The variance of each factor were 23.7%, 8.3%, 4. 7%, 4.1%, and 3.3% respectively in that order. The Eigen value of each factor was 13.03, 4.57, 2.60, 2.23, and l.83 respectively. It was found that the Taegyo is an unique and holistic self care behavior of Korean pregnant women. Therefore it has been concluded that this study has broadened the understandability of the implications the Taegyo. It is suggested that further studies on the effects of the Taegyo are needed to provide a scientific basis for professional maternity nursing.

  • The morphological development of the carotid body was studied by electron microscope in human fetuses from 40mm to 260mm crown rump length (10-30 weeks of gestational age). At 40mm fetus, the carotid body was composed of cluster of primitive glomus cells, primitive supporting cells, unmyelinated nerve fibers, and blood capillaries. In connective tissue between internal and external carotid arteries adjacent to the superior cervical sympathetic ganglion, two types of glomus cells through all prenatal period were found. Dark cells contained a dense cytoplasm with conspicuous large dense-cored granules, whereas light cells had a less dense cytoplasm with dense-cored granules. The light cells contained dense-cored granules that were smaller and less abundant than those in the dark cells. The primitive supporting cells appeared star-shaped with attenuated cytoplasmic extensions intervening between the adjacent glomus cells. Synaptic contact between the axon terminals and soma of the glomus cells were first observed at 40mm fetus. In 80-100mm fetus, the carotid body contained tightly packed collection of glomus cells and supporting cells which surrounded the abundant thin-walled blood vessels. Intercellular junctions between the glomus cells and adjacent cells were commonly seen. Nerve endings on the glomus cells have the form of small boutons and the other from of large calyces. During the second half of the fetal period, the glomus cells were completely enveloped by supporting cells and nerve terminals. At 260mm, the morphological features of carotid body were similar to those of human adult. The result of this study demonstrates that there are differences between the carotid body and aorticopulmonary bodies, especially with respect to their synaptic complexes, abundant blood capillaries, and two glomus cell types.

  • Plasma progesterone (P$_4$) concentrations were measured for confirming the estrus observation and for the early pregnancy diagnosis in 130 cows of small farmers. Ultrasonographic examinations were performed from day 30 after artificial insemination to establish the characteristic ultrasonographic appearances of gestational structures in each pregnant stages. Of the 130 cows inseminated, 111 cows (85.4%) were an ovulatory estrus, 12 cows (9.2%) were an unovulatory estrus, and 7 cows (5.4%) were the error of estrus detection, respectively. The accuracy for early pregnancy diagnosis in 111 ovulatory estrus cows achieved when the discriminatory concentration at day 21 after artificial insemination was placed at 3.0 ng-/ml in plasma, was 86.7 % for positive diagnosis and 100% for negative diagnosis, respectively. Pregnancy diagnosis by ultrasonography were performed to evaluate gestational structures from day 30 after artificial insemination in 83 cows. Pregnant cows were 72 of 83 cows. The characteristic ultrasonography of gestational structures in each gestational stages was as follows. The embryo proper was observed within anechoic fetal fluid between 28 and 40 days after insemination, and amnion and embryonic heartbeat was also detected in this period. Between days 41 and 50, embryo proper was detected as an discriminated from head and body, and forelimb buds and hindlimb buds were also observed in this period. Between days 51 and 60, an embryo proper was clearly discriminated from head and body, and fetal movement, forelimb buds and hindlimb buds were observed in this period. Between days 61 and 70, fetus was completely developed, and fetal skeleton, organs and cotyledon were observed. After day 71, each organs of fetus were rapidly developed and a fetus was partially observed in screen because fetus was too big and larger, These results indicate that plasma P$_4$ determination at days 0,6 and 21 after artificial insemination can be utilized for confirming the estrus observation and for early pregnancy diagnosis. Also, ultrasonography was reliable method for early pregnancy diagnosis at day 30 after artificial insemination.

  • Objectives: To study the effect of Artemisiae Capillaris Herba extracts, that have been used as oriental medicine to treat liver disease, on the perinatal and lactational n;)productive toxicity of SD rats when administered by oral lavage. Methods: Female SD rats were dosed from 6 days of gestation to 3 weeks postpartum. This was conducted in accordance with the recommendations of the KFDA Guidelines for Detection of Toxicity to Reproduction for Medicinal Products. Results: No Artemisiae Capillaris Herba extracts treatment-related changes in clinical signs, mortalities, implantation number, dead fetus number, loss rate of fetus, number of live young, survival rate of fetus, sex ratio of live young, external anomalies, pregnancy periods, viability index, lactational index, survival rate of litters at 4 days after birth or delivery index were demonstrated in any dosed levels in this study. However, the body weight and gains, food consumption and absolute organ weights of brain, adrenal glands, liver, spleen, kidney, ovaries and heart were significantly increased in 2000 or 1000mg/kg-dosing groups and the relative organ Weights of adrenal glands were significantly increased in 2,000mg/kg-dosing groups. Therefore, it was concluded that this increase was natural according to growth. Also, no changes of gross findings, clinical signs, mortalities, body weight and gains, physical development results, necropsy findings, organ weight, faculty test, open filed test and water-filled simple T-maze test, copulation, fertility, pregnancy indices, body weight and gains during gestation periods, necropsy findings, corpora lutea number, implantation number, implantation rate, dead fetus number, post-implantation loss rate, live young, post-implantation survival rate, sex ratio of live young, external anomalies and individual body weights of live young were demonstrated in any dosed levels in this study. Conclusions: It is considered that the NOAEL (No-Observed-Adverse-Effect Level) for perinatal and lactational reproductive toxicity of Artemisiae Capillaris Herba extracts was up to 2000mg/kg/day because no changes of other perinatal and lactational reproductive indices were demonstrated.

  • The prenatal development of thoracic spinal cord was studied by electron microscope in human embryos and fetuses ranging from 9mm to 260mm crown-rump length (5-30 weeks of gestational age). Ependymal cells in all fetal ages had conspicuous junctional complexes close to the lumen of the central canal into which microvilli and cilia projected. The ependymal cells contained numerous longitudinally arranged mitochondria, flattened cisternae of endoplasmic reticulum and Golgi complex. At 20 mm embryo, the floor and roof plates were composed of ependymoglial cells and undifferentiated neuroepithelial cells. The neuroepithelia of the sacral spinal cord were delineated from central medullary cord. By 100 mm fetus few undifferentiated neuroepithelial cells remained in the floor and roof plates. At 150 mm fetus, the whole central canal was formed by ciliated columnar epithelial cells containing cilia with basal bodies. The microvilli became tangled and club-shaped and formed a matted surface. The canal was filled with areas of dark and pale amorphous materials bounded by membrane-like structure. These two types of material were found throughout the whole central canal from 100 mm fetus onwards. By 260 mm fetus, microfibrils were first observed in the ependymal cells. In conclusion, it seems that early development and differentiation of central canal ependyma are simlar to that in other part of the brain ventricular system although ependymoglial cells are more prominent.

  • Purpose: This study was done to evaluate effects of a mother-fetus interaction promotion program on maternal and infant sleep/activity regulation, and examine the correlation between maternal and infant sleep/activity. Methods: Thirty-four mother-infant dyads were recruited from an OB-GY clinic with postpartum care center, and assigned to the intervention group (17) or control group (17). Data were collected from January 18 to August 5 2005. A programmed education focused on mother-fetus interaction was provided to the intervention group in the 3rd trimester. Maternal sleep/activity record was completed at 32-36 weeks gestation and infant sleep/activity record was completed for one month after birth. Results: During the 3rd trimester, there were no significant differences in maternal sleep/activity between the groups, except for frequency of mothers' night awakening and urination at night. There were no significant differences in infant sleep, but significant difference was found in feeding times between the groups. Correlation of maternal sleep in the 3rd trimester and infant waking times was significant. Conclusion: The results of this study indicate that maternal sleep/activity during pregnancy influences infant sleep/activity at 3-4 weeks, and that nursing interventions to regulate maternal sleep/activity provided to primiparas can be beneficial to the regularity of infant sleep/activity patterns.
