Purpose: The purpose of this study was to explore the effects of a taegyo program on parents-fetal attachment and parenthood in first pregnancy couples (mothers and spouses). Methods: The research design was a nonequivalent control group pretest-posttest experiment. Study participants were 52 first pregnancy couples visiting two medium-scale obstetrics and gynecology clinics located in Gwangju. A total of 52 couples were assigned to the experimental group (25 couples) and the control group (27 couples). The experimental couples were provided with a taegyo program for 4 weeks. Data were analyzed by chi square test, t-test, and ANCOVA using the SPSS program. Results: Post-treatment maternal- fetal attachment, paternal-fetal attachment and motherhood significantly increased in the experimental group as compared to the control group, but post-treatment fatherhood, anxiety, blood pressure and pulse of participants in the experimental group showed no significant difference from those in the control group. Conclusion: From these results, it is suggested that the taegyo program has beneficial effects in enhancing parent-fetal attachment and motherhood in first pregnancy couples. Therefore, a taegyo program can be recommended as a nursing intervention program for first pregnancy couples.

In order to estimate the human placental lactogen levels and its value as an indicator of placental function during the first half of normal pregnancy, we defermined HPL levels. in normal snbjects (No=40) from the 6th week to the 20th week of gestation For the determination of human placental lactogen in serum of normal pregnant women during the first half of prognancy, radioimmunoassay have been performed using Phadebas HPL Test kit. The range of 25ng to 800ng HPL/ml. were determined by the procedures using Phadbas HPL Test kit, which correspond to levels recorded throughout the first half of normal pregnancy. HPL was detected in the earliest pregnancy samples collected at 6 weeks but was generally present in minute amount during the first trimester of pregnancy, when the HPL level ranged from 25 ng/ml. to 0.86 ${\mu}g$/ml. The mean concentration of HPL increased gradually from only 0.03 ${\mu}g$/ml, at 6 weeks to 0.25 ${\mu}g$/ml, at 12 weeks of gestation, Subsequently the mean HPL value rose steeply from 0.25 ${\mu}g$/ml, at 12 weeks to 1.65 ${\mu}g$/ml, at 20 weeks of gestation.

Purpose: To develop Pregnancy Risk symptom Perception Scale (PRPS) and evaluate its validity and reliability. Methods: A preliminary 30-item version of PRPS was developed through literature review, in-depth interview, and Content Validity. Each item was scored on a four-point Likert scale. The preliminary scale was developed based on 301 pregnant women who visited a hospital. Date were analyzed using item analysis, factor analysis, confirmatory factor analysis, Pearson's correlation coefficients, and Cronbach's ${\alpha}$ (0.90 for total item, 0.80 to 0.88 for factors). Results: The PRPS consisted of 27 items. Three factors (physical, environmental, and emotional factors) explained 55% of the total variance. Cronbach's Criterion validity was supported by comparison with the Perception of Pregnancy Risk Questionnaire (r=0.34). In reliability test, the reliability coefficient of pregnancy risk symptom perception was high at 0.90. Conclusion: These results suggest that the pregnancy risk symptom perception scale developed in this study comprises items that can assess the level of pregnant women's pregnancy risk symptom perception in Korea. Its validity and reliability were proven. PRPS can be utilized to measure pregnant women's risk symptom perception during pregnancy. PRPS will contribute to the development of systematic prenatal care and effective risk management.

Objectives: In recent years, pregnancy rate among female adolescents has increased and caused a variety of physical and social problems. Therefore, this study aimed to investigate sexual behavior, delinquent behavior, and pregnancy rate among Korean female adolescents. Methods: In light of the growing interest in adolescent pregnancy, this study conducted a web-based survey, titled "The 2006 Youth Health Risk Behavior Survey." The Korean Center for Disease Control (KCDC) collected questionnaire responses from 34,200 young women. The collected data were analyzed through chi-square test and logistic regression using SPSS Win 14.0 version. Results: This study analyzed main factors, which can predict pregnant experience. The statistic results showed two types of the predicting factors: (1) personal factors: sexual relations after drinking (odds 25.1), Narcotic drug taking (odds 13.0), sexual violence act (odds 7.0), part-time job(odds 2.5), drinking, smoking ; and (2) environmental factors: stepfather(odds 4.2) and natural mother. Conclusion: The influential factor identification for predicting pregnancy rate is important to develop an effective education program for preventing the adolescent pregnancy. The education programs with referring to the identified factors can contribute to reducing the unwilling pregnancy rate of young woman.

Purpose: The study was to explore the level of low back pain and characteristic factors influencing low back pain (LBP) and mental health during pregnancy. Methods: The subjects were a total of 383 healthy pregnant women in S City and K-Do. Data were analyzed using descriptive statistics, t-test, ANOVA, and Pearson's correlation. Results: 82.5% of the pregnant women answered the existence of LBP and 19.7% of them had high LBP. The preferred method of controlling LBP was 'Just endure'(42.3%). There were significant differences in pregnancy level (p<.05) and discomfort condition related to pregnancy (p<.01) according to low back pain. There were significant differences in pain intensity according to mental health. The correlation between pain level and pregnancy weeks (p<.001) and BMI in previous pregnancy (p<.001) was significant. The correlation between mental health and age was significant (p<.001). Conclusion: The majority of the pregnant women experienced LBP during pregnancy. However, they were not offered the best method of controlling the pain. Thus, for preventing LBP during pregnancy, we recommend regular exercises and BMI control.

Purpose: To determine whether maternal attitude toward sex during pregnancy and health-related quality of life could influence sexual function of pregnant women. Methods: In this study, 138 second and third trimester pregnant women completed self-report questionnaires during their visits to women's hospitals or community health centers to assess their general characteristics, attitude toward sex during pregnancy (PIES-M), health-related quality of life (EQ-5D), and sexual function (FSFI-6K). Multiple regression analysis was performed to test the research model with SPSS version 23. Results: Pregnant women who had discontinued their sexual life after recognizing their pregnancy accounted for 27.5% of women questioned. The average sexual function score of pregnant women was higher in the second trimester than the third trimester. Attitude toward sex during pregnancy (${\beta}=-.38$, p<.001), maintaining sexual life (${\beta}=.20$, p=.028), health-related quality of life (${\beta}=.18$, p=.030), and adverse symptoms during sex (${\beta}=.18$, p=.042) were determinants of sexual function during pregnancy. Conclusion: Nurses in antenatal care units need to help pregnant women maintain a positive attitude toward sexual activity during pregnancy and manage their health-related quality of life to maintain their sexual life during pregnancy.

Purpose: The purpose of this study was to examine the awareness of alcohol use during pregnancy and factors influencing the intention to abstain from alcohol during pregnancy by drinking levels. Methods: Utilizing a comparative descriptive design, a total of 359 female college students were recruited. Measurements were Theory of Planned Behavior (TPB) variables related awareness of alcohol use during pregnancy, Korean Version of the Alcohol Use Disorders Identification Test, knowledge about alcohol use during pregnancy, and socio-demographic factors. Main variables were compared by drinking levels. The factors influencing the intention to abstain from alcohol during pregnancy were identified using hierarchical regression analysis. Results: Non-problematic alcohol behavior group (n=185) had higher the intention to abstain from alcohol during pregnancy than problematic alcohol behavior group (n=174) (t=3.13, p=.002). The significant TPB variables influencing the intention to abstain from alcohol during pregnancy were that attitudes (β =-.44, p<.001), subjective norms (β =.14, p=.026), and perceived behavior control (β =.19, p=.002) in non-problematic alcohol behavior group, whereas the corresponding variables in the problematic alcohol behavior group were attitudes (β =-.51, p<.001) and subjective norms (β =.21, p=.006). Conclusion: It is necessary to increase the intention to abstain from alcohol during pregnancy for the female college students having problematic alcohol behavior. The following strategies are recommended for them; decreasing acceptable attitudes toward alcohol use during pregnancy and reinforcing the influence of social pressure toward to abstain from alcohol during pregnancy.

The experiment was carried out to study the profile of uterine specific protein during early pregnancy in sows and to test it's immunosuppressive activity. Uterine protein samples were obtained by flushing the uterine horn on Day 3, 6, 9, 12 and 15 of the estrous cycle and the pregnancy respectively and the protein concentration of each sample was determined. The change of uterine protein was examined by sodium dodecyl sulfate(SDS)-PAGE. The immunosuppressive activity of uterine secretory protein was investigated according to the lymphocyte blastogenesis response to mitogen. The results of this experiment are summarized as follows ; 1. The uterine protein during estrous cycle and early pregnancy was relatively constant up to Day 9, but increased on Day 12. Maxium total protein values were found on Day 15. The concentration of serum proteins were about 82-95 mg during estrous cycle, but decreased to about 70-82 mg during early pregnancy. 2. The proteins components similar electrophoretic patterns(PAGE) that were no differences (band ; a, b, c, d, e, f, g, I) on Days 3, 6 and 9 of the estrous cycle and pregnancy. But there were more 2 bands specifically on Day 12 of the pregnancy and on Day 15 of estrous cycle and showed more 4 bands on Day 15 of early pregnancy. They seemed to be acidoprotein and their average molecular weight were 38,000, 22,300 and 12,600. 3. When uterine protein were added 500$\mu\textrm{g}$/ml, there was no immunosuppresive activity on Day 3 of estrous cycle and lymphocyte blastogenesis was slightly suppressed on Day 3 of pregnancy. The immunosuppressive activity on Day 9 of estrous cycle and pregnancy appeared in 500$\mu\textrm{g}$/ml and 150$\mu\textrm{g}$/ml, respectively the uterine protein on Day 12 and 15 showed immunosuppresive activity, which at the level of 150$\mu\textrm{g}$/ml during non-pregnancy and at the level of 100 to 125$\mu\textrm{g}$/ml during early pregnancy, respectively.
