To investigate the effect of parents' social class on birthweight in Korea during the period of transition to a market economy, 1995-2001. Methods: All births resulting from pregnacies reported in 1995-22001(n=4,298,374) were studied with respect to social variation in birthweight. The results were adjusted for maternal age, parity, parents' education, gestational age, total births, the dead births among total births, the number of births in one delivery. Results: Between 1995 and 2001, mean birth weight was 3271g and low birth rate was 3.41%. Maternal education, faternal education, parents' occupation, the number of birth in one delivery, total births, gestational age, and the number of deaths among. total births were all independently related to the birthweight. Parents with lower education showed higher low-birthweight rates compared with parents with university level of education(OR: 2.16 for mother and 1.68 for father). Especially, mother's education showed stronger relationship with birthweight than fathers' education. The differences in birth weight by parents' social class, especially parents' educational level became stronger between 1995 and 2001. Discussion: This study suggests that the social differences of birth weight were increasing in order 1995 to 2001. Especially, this increasing tendency in variation in birth weight by social class was shown after economic crisis, 1998.

Purpose: The purpose of this study was to investigate the outcome after changes in the treatment strategies for very low birth weight infant (VLBWI) in a single neonatal intensive care unit (NICU) center. Methods: We performed a retrospective review of 300 VLBWI born from 1st January 2010 to 31th December 2016. We compared the outcomes including survival rate, birth weight (BW), gestational age (GA), and morbidities between period I (2010-2013, P-I) and period II (2014-2016, P-II). Results: The average survival rate was not different between P-I and P-II. However, the survival rate of ${\leq}24$ weeks' GA, 25 weeks' GA, 26 weeks' GA were 57%, 69%, 93% respectively in P-II and 31%, 59%, 87% in P-I respectively. The survival rate of infants with birth weight <500 g, 500-749 g, 750-999 g were 100%, 55%, 90% respectively in P- II and 50%, 24%, 80%, respectively in P-I. The incidence of bronchopulmonary dysplasia (BPD) was higher in P-II than in P-I (P=0.012) and moderate-to-severe BPD was also higher in P-II (P=0.004). Incidence of patent ductus arteriosus (PDA) with treatment, necrotizing enterocolitis (stage ${\geq}2$), and abnormal brain sonography were significantly lower in P-II (P=0.027, P=0.032, P=0.005). Incidences of retinopathy of prematurity (ROP) with laser treatment and early sepsis were not different. Conclusion: The survival rate and complications of VLBWI were improved in period II, especially in less than 750 g and below 26 weeks, except incidence of BPD. Changes of NICU strategies were effective to improve mortality and morbidity in VLBWI.

Objective: Piglet pre-weaning mortality is an important variable indicating the efficacy of farrowing management and animal well-being during lactation. The present study determined the association of newborn traits measured soon after birth with piglet pre-weaning mortality and growth. Methods: In total, 805 piglets born from 57 multiparous sows were investigated. Their blood oxygen saturation, blood glucose and rectal temperature at 24 h after birth (RT24h) were monitored. Birth order, sex, skin color, integrity of the umbilical cord, attempts to stand and birth intervention were monitored. Piglets were weighed at day 0, 7, and 21 to evaluate average daily gain (ADG). Results: Piglet pre-weaning mortality for lactation period was 12.6% and cumulative mortality during the first 7 days of age was 8.6%. A higher proportion of piglets with pale skin color died compared to piglets with normal skin color (26.7% vs 7.7%, p<0.001). A higher (p<0.001) proportion of piglets that attempted to stand after 5 min (38.5%) died compared to piglets that attempted to stand within 1 min (6.3%) after birth. Piglet body weight at birth ($BW_B$), blood glucose and the number of piglets born alive (BA) were correlated with ADG (p<0.05). Piglets with $BW_B$ <1.30 kg had higher (p<0.001) mortality rate than piglets with $BW_B{\geq}1.80 kg$ (19.0% vs 3.3%) and piglets with $BW_B$ 1.30 to 1.79 kg (4.0%). Piglet with RT24h <$37.0^{\circ}C$ had higher (p<0.001) mortality rate (86.2%) than piglets with RT24h >$38.5^{\circ}C$ (3.9%). Conclusion: Low $BW_B$ and low RT24h compromise piglet survival during the lactation period in the tropical conditions. Piglets in the litters with a high BA, low $BW_B$ and low blood glucose have reduced ADG.

본 연구는 한국보건사회연구원의 "2009년도 전국 결혼 및 출산 동향 조사" 패널자료를 활용하여 20~44세에 이르는 2,678명의 미혼 남녀(남 1,425명, 여 1,253명)가 생각하는 이상적인 일 가정 양립 방안, 성역할 태도 및 저출산 원인에 대한 견해 등을 성별 및 교육정도에 따라 알아보고 이들 사이의 관계를 탐색적으로 분석해 보았다. 이를 통해 향후 저출산 문제 해결을 위해 미혼 남녀들의 일 가정 양립을 어떻게 지원할 것이며, 이 과정에서 미혼 남녀의 성역할 태도가 어떻게 변화되어야 할 것인가를 유추해 보고자 했다. 연구결과를 정리하면, 첫째, 이상적인 일 가정 양립 방안은 미혼자의 성별에 따라 차이가 없었으나 교육정도에 따라서는 통계적으로 유의한 차이가 드러났다. 둘째, 이상적인 일 가정 양립방안과 부부 성역할 태도 및 성별 간 관계에 있어서는 여성에 비해 남성이 '남성은 직장, 여성은 가사'를 더 찬성했으며, 전일제일 보다 시간제 일을 선호하는 미혼자들이 '남성은 직장, 여성은 가사' 방안에 대한 찬성이 높았다. '남편의 자녀 돌봄 능력'에 대해서는 여성이 남성보다 그리고 2자녀를 두고 전일제로 일하겠다는 미혼자가 1자녀를 두고 전일제로 일하겠다는 미혼자에 비해 높은 평가를 보였다. 셋째, 두 자녀 이상을 두고 전일제로 일하고자 하는 미혼 남녀가 저출산 문제를 가장 심각하게 받아들이고 있었다. 넷째, 저출산 이유로 가장 높은 동의를 보인 것은 '양육비와 교육비용'이었으며 다음으로 '주택마련의 어려움'과 '취업여성의 증가'였다. "취업여성의 증가"를 저출산의 원인으로 여기는 정도는 남성보다 여성이 높게 나타났으며, 무자녀로 전일제 일하는 것을 원하는 미혼자들에게서 이러한 성향이 두드러지게 나타났다. 이러한 연구결과를 통해 일 가정 양립방안과 성역할 태도에 대한 기본적인 이해를 높일 뿐만 아니라 저출산 문제에 대한 정책적 개입방향을 제시하고자 하였다.

한국의 지속적인 저출산은 세계적으로 유례가 없을 정도의 급격한 고령화 속도와 맞물려 국가경쟁력 및 사회보장 시스템을 약화시키는 요인이 되었다. 저출산 문제를 해결하기 위하여 정부에서는 각종 출산장려정책을 실시하고 있으나, 현재까지 저출산에서 벗어나지 못하고 있어 정책이 효과적이지 못하였던 것으로 평가된다. 그러므로 본 연구에서는 보다 효과적인 정책개발의 근간을 마련하기 위하여 조건부 순위별 출산율을 제안하고, 이를 이용하여 한국의 출산정책 효과를 파악하였다. 조건부 순위별 출산율을 사용하면 순위별 출산율을 사용하는 것보다 합계출산율의 변화와 효과를 명확히 산출할 수 있으므로, 다양한 순위별 출산율의 시나리오에 따라 합계출산율의 변화를 비교하였다. 이를 통하여 현재 정부의 셋째 아 출산지원 정책으로 도달할 수 있는 합계출산율 및 둘째 아 또는 첫째 아의 출산지원을 하였을 때 도달할 수 있는 합계출산율을 산출할 수 있었다. 또한 지속적인 저출산으로 빠르게 감소하고 있는 가임여성(15-49세)을 고려하여 합계출산율에 따른 출생아수를 함께 제시하여 실질적인 출생아수의 증가를 유도하는 정책개발에 도움이 될 수 있도록 연구결과를 정리하였다.

This study examined characteristics among 131 infants who were born at three hospitals affiliated with Catholic University. Those infants were very low birth weight infants (VLBWI ). Data were gathered through review of medical records between 1990 to 1993. The results were as follows : 1. Regarding the birth weight, 72.6％ were between 1000 gm to 1500 gm and 27.4% were below 1000gm. Of the VLBWI, 27.5% had gestational age of 29-30 weeks and 22. lof had gestational age of 26 weeks and below. The birth weight of them was significantly correlated with their gestational age. 2. Most of VLBWI had been hospitalized for more than 30 days and particulaly those who were between 1100-1400gm had been hospitalized more than 60 days. And the number of clinical problem was the most influencing factor on their discharge. 3. Of the VLBWI, 28.2% were given gavage feeding. 4. Jaundice appeared predominantly on the 3rd day after birth ,with 64.1％ of incidence rate. Of those infants developed jaundice, 92.9% received phototherapy 5. The most common problem after birth was respiratory conditions. And oxygen therapy was administered for 93.9% of the VLBWI while they were in the hospital.

The Low Birth Weight infant birth rate in this country is a little more than 15 percent and is being increased. The survival rate of Low Birth Weight infant is over 90 percent and recently the rate runs is getting. However, because of the high risk of Low Birth Weight infant for handicap in growth, a preventive nursing intervention program for Low Birth Weight infant and their mother is considered to be necessary. Touch and massage, thus sensory stimulation has been considered to be important ensuring a normal growth of Low Birth Weight infant During the past decades sensory stimulation program has been used for premature and Low Birth Weight infants. Recently a study on the sensory stimulation for Low Birth Weight infants has bee n done in this country. Mother and infant relationship has a great influence on child's development. Especially, mother and infant interaction during one year after birth plays important role in child's social. affective and cognitive developments. But in the study of Low Birth Weight infants, the mother and infant interaction has been rare yet. However, there was no study effectiveness of the sensory stimulation on mother and infant interaction. In this respect, this study based on the importance of the nursing intervention, is intended to measure the effectiveness of the massage therapy in the aspects of weight, daily feeding amount, cortisolurine stress hormone and mother and infant interactions. This study has been conducted on the nonequivalent control group pretestposttest design in quasi experimental basis and Low Birth Weight infants from NICU of two Medical University Hospitals located in Taegu Metropolitan were selected in experimental group of 21 infants and control group of 20 infants. Data has been collected from May 1, 1999 to September 5, 2000. For the experimental group Field's sensory stimulation(tactile and kinesthetic stimulation) was applied 2 times a day for 10 days(10:00 - 11:00 hours in the morning and 19:00 - 20:00 in the afternoon) by nurse and mother. The electronic indicator scale (Cas Co. Korea) was used to measure infant's body weight. To determine urine cortisol concentration level under stress, rad immuno assay method was used. And to determine mother and infant interactions during feeding, tools developed by Kim Mi-Ye (1999) were used. Collected data were analyzed with SAS program using x-test, t-test, paired t-test and repeated measures ANOVA. Findings were as follows : 1. For the daily mean weight gain, the experimental group showed little higher than the control group, even though, there was no Statistically significant differences between two groups. 2. For the amount of daily mean feeding, the experimental group showed little higher than the control group, while there was no Statistically significant differences between two groups. 3. The level of wine cortisol concentration was increased in both groups, while no Statistical significance was shown between the two groups. 4. Mothers in experimental group were more likely to have higher mean scores in mother and infant interaction during feeding than mothers in the control group. Statistical significance was shown between the two groups(t= 5.78, P=.001). In conclusion, the massage therapy in this study showed with regard to even though through there was no statistically significance in the weight gain and urine stress hormone concentration. there was Statistical significantly higher in the mother and infant interaction during feeding. Based on the result of this study, it is considered that the massage therapy should be applied clinical practice and home to help a developmental growth and interaction of Low Birth Weight infants and mothers during the period of recovery.

A rapid decrease of total fertility rate to 1.08 in 2005 prompted the Korean government to plan and implement a '5-year plan for ageing society and population policy' starting from 2006. The 1st and 2nd 5-year plans had not shown any discernible impact on the fertility and the 3rd 5-year plan was launched in 2016. However, the fertility rate is going down further. The author reviewed the contents and assessment reports of the fertility promotion plan to suggest ideas for complementing the shortcomings of it. Author defined the major determinants of marriage and child birth as philosophy, politics, sense of value, social norm, culture, healthcare, and education. The plan was examined in view of these determinants. Transformation of Korea from an agricultural society to an industrialized society in a short period of time had brought about changes in most of the determinants of marriage and child birth; in particular philosophy and sense of value. These aspects were not put into consideration in the plan. Author suggested to launch a social education program for the general public to establish a sound philosophy of life, reform the sense of value on family, child birth and education, and cultivate the skill to draw a consensus through discussions on the social issues. A special program to promote marriage of women at the optimum age for child birth was proposed. The government should implement well balanced policy for economic development and labor. Multidisciplinary approach was recommended for these tasks.

The measurement of $17{\alpha}$-hydroxyprogesterone ($17{\alpha}$-OHP) in a dried blood spot on filter paper is an important for screening of congenital adrenal hyperplasia (CAH). Since high levels of $17{\alpha}$-OHP are frequently observed in premature infants without congenital adrenal hyperplasia, we evaluated cuts-off based on birth weight and performed validation. Birth weight and $17{\alpha}$-OHP concentration data of 292,204 newborn screening subjects in Greencross labopratories were analyzed. The cut-off values based on birth weight were newly evaluated and validated with the original data. The mean $17{\alpha}$-OHP concentration were 7.25 ng/mL in very low birth weight (VLBW) group, 4.02 ng/mL in low birth weight (LBW) group, 2.53 g/mL in normal birth weight (NBW) group, and 2.24 ng/mL in heavy birth weight (HBW) group. The cut-offs for CAH were decided as follows: 21.12 ng/mL for VLBW and LBW groups and 11.14 ng/mL for NBW and HBW groups. When applied new cut-offs for original data, positive rates in VLBW and LBW groups were decreased and positive rates in NBW and HBW groups were increased. The cut-offs based on birth weight should be used in the screening for CAH. We believe that our new cut-off reduce the false positive rate and false negative rate and our experience for cut-off set up and validation will be helpful for other laboratories doing newborn screening test.

The purposes of this study were to identify and compared the selection conditions of spouses and the perceptions of marriage and childbirth by sex. Moreover, this study tried to find the number of child the study subjects want to have in their marriage and what factors were important for whether they have no or one child or more than two children. The study subjects were college students who were belong to 6 health care related departments selected randomly from all health care related departments in one metropolitan area. In the selection conditions as their spouses, they ranked 'love', 'personality' and 'wealthiness' as important factors in order. Male ranked females' employment as 10th but female ranked it 5th. In conclusion, there were concordances and dis-concordances on the perceptions of marriage and child birth by sex. Understanding these factors caused by gender roles in our society could contribute to making new policies for promoting marriage rate in younger age and overcoming the problems of low birth rates by giving more specific data to policy makers for increasing child birth rate.
