  • This study reviews the relationship between son preference and fertility behavior, and infant and chlid mortality in the context of fertility and mortality decline. In Korea the situation reveals that fertility can decline to a very low level even in the presence of strong son preference, but son preference has certain effects on fertility and childhood mortality. The effect of son preference on fertility increased as the level of fertility declined. Our findings show that son preference causes excess female childhood mortality both directly and indirectly through fertility. Also, in Korea, the analysis reveals that female children suffer excessively high level of mortality and part of the excess mortality is due to parents' behavior on family building related to the effort to secure the birth of a son.

  • This study examined the effect of parental socioeconomic position on the association between birth outcomes and infant mortality in early and late 2000's. Linked Birth and Infant Death data sets from 2001 to 2003 (T1) and from 2006 to 2008 (T2), provided by the Korea National Statistical Office, were used for analysis. Birth outcomes were categorized into four groups: normal term, small-for-gestational age (SGA), large-for-gestational age (LGA) and intrauterine growth retardation (IUGR). Infant death was defined as the death of a live-born child under one year of age; indicators of parental socioeconomic position were limited to parental education and occupation. The results showed that T2 infant mortality hazard ratios of SGA and IUGR have increased compared to T1. Particularly, preterm and low birth weight babies with shorter gestational age and lighter birth weight than T1 have elevated in T2, possibly indicating that population quality might be continuously aggravated. Moreover, the effect of maternal age on infant mortality has disappeared, rather that of parents' socioeconomic position has increased during the periods, which entailed growing disparities in infant mortality by their social class. Further studies should be therefore done to estimate the effect of parental socioeconomic position on the relationship between birth outcomes and infant mortality in the near future.

  • This study investigates birth cohort and educational differences in the marital and fertility life course using the Hernes model. First, lifetime marriage rates remain high across birth cohorts but men in the youngest birth cohort(1965-74) experience a somewhat significant reduction in ever-marriage rates. Second, this study also finds educational differences in lifetime marriage rates across birth cohorts. The likelihood of being never married is particularly high for poorly educated men in the youngest birth cohort but women show the opposite pattern. Third, quantum changes in the fertility transition are more likely to be the changes in higher-order births, while the changes in first and second births are mainly tempo changes. Fourth, the negative association between education and fertility is significantly larger for higher-order births. Finally, marriage and fertility show the opposite pattern in their association with education. Overall, educational differences in lifetime marriage rates become stronger across birth cohorts but the association between education and higher-order births shows the opposite pattern.

  • 우리나라 서해안의 폐염전 또는 대하양식장을 이용한 해산어 종묘생산이 조피볼락, 감성돔, 숭어 등을 대상으로 이루어지고 있다. 이렇게 생산된 종묘는 기형개체가 전혀 없는 건강 종묘이며, 생산 원가 또한 육상수조식에 비해 최고 5배정도 낮다. 한편 참돔은 육상수조에서 종묘생산시 기형률이 비교적 높게 나타나므로 노지를 이용한 종묘생산이 요구되고 있다. 현재 노지 종묘생산시 요각류 번식을 위한 시비제로는 암모니아, 인산염, 칼륨 등이 함유되어 있는 화학비료(요소, 복합비료)나 계분, 돈분, 우분 등의 유기질 비료가 주로 사용되고 있다. 그러나 화학비료를 사용시 급격한 수질변화로 요각류의 폐사가 발생하고, 매년 지속적인 생산량을 기대하기가 어려운 문제점이 있다. 따라서 적절한 시비제를 구명하기 위하여 유기질 비료(알팔파, 숙성계분)와 화학비료(요소, 복합)를 단독 또는 병행 사용하여 2개월간의 동ㆍ식물플랑크톤의 변동량과 치어의 생존율을 조사한 결과, 유기질 비료는 부화자어가 입식된 이후에도 연속하여 시비하여도 생존율에 영향을 미치지 않았으나, 화학비료의 경우 일정 농도 이상에서는 동ㆍ식물플랑크톤의 번식에 장애를 초래하였고 이에 따라 자어가 전량 폐사하였다. 실험군의 생존율은 육상수조에서 40%, 알팔파와 숙성계분을 시비한 실험군이 15%, 요소, 복합, 알팔파를 시비한 실험군이 10%, 요소, 복합, 숙성 계분을 시비한 실험군이 8%, 요소와 복합을 시비한 실험군은 0%를 나타내었다. 또한 기형률에 있어 노지 실험군은 0.7%로 매우 낮게 나타났으나, 육상수조 실험군은 61%에 해당하는 치어가 기형이었으며, 그 형태도 다양하게 나타났다.fer, Artemia sp., copepods, 부화 25일째부터는 copepods였다. 초기성장은 부화직후 전장 1.95 mm였던 것이 10일째는 2.96 mm, 20일째는 3.89 mm, 30일째는 12.9 mm, 50일째는 35.1 mm를 나타내었다. 그러나 말쥐치 자ㆍ치어가 성장함에 따라 발생하는 지속적인 폐사와 종묘의 수송시 발생하는 폐사를 줄일 수 있는 방법이 추후에 해결되어야 할 것으로 사료된다.8,000~215,000 마리의 자어를 낳아서 개체에 따라 큰 차이를 나타내었다. 1999년에는(어미 : 전장 20.7~25.5cm, 체중 205.5~396.4g) 1 회 출산때마다 7,000~50,000 마리의 자어를 출산하였다. 3. 출산간격. 다회 출산한 쏨뱅이 어미가 첫 번째 출산에서 다음 출산까지 소요되는 기간을 조사한 결과 13일에서 25일이 걸리는 것으로 나타났다. 특히 4회 출산 한 1998년 쏨뱅이 어미는 첫 번째 출산 후 19일만에 두 번째 출산이 이루어 졌고 각각 13 일과 14 일만에 세 번째, 네 번째 출산이 이루어져 총 46일 동안 4회에 거쳐 자어를 출산하였다. 4. 출산자어의 크기. 1997년 3회 출산한 쏨뱅이의 출산시기별 자어 크기를 조사한 결과 첫 번째 출산에서는 평균전장 4.1$\pm$0.07mm의 자어를 낳았으나 두 번째 출산에서 자어의 크기는 평균전장이 3.9$\pm$0.11mm, 세 번째 3.8$\pm$0.12mm로 점차 작은 경향을 나타내었다..27mm(평균 1.76mm, n=20) 그리고 Snout length 0.74~l.67mm(평

  • This paper explores the effects of the 1997 economic crisis on the pattern of socioeconomic differentials in fertility. Based on analysis of data from the 2003 Korea National Fertility Survey, this study focuses on recent changes in the level of fertility according to socioeconomic status of the couple including educational level, occupation, working status, income, etc. Results reveal that the level of fertility of those with the highest education, most prestigious occupation, and employer status are higher than those of the next group in the socioeconomic hierarchy. These findings imply that the straight line inverse pattern of socioeconomic differentials in CEB yielded to a reversed J-shaped curve. However, recent differentials of fertility after the economic crisis were found to contrast with the pattern above. Decrease in fertility has been most drastic among those with a high level of fertility, and relatively slow for those with a low level of fertility. The level of recent fertility turns out to be highest among those with upper-middle socioeconomic status, followed by those with the highest socioeconomic status and those with the lowest status. Policy implications and some comments on current population policies of the Korean government are also presented in this paper.

  • The study was conducted to identify factors that affect the first childbearing decisions among married working women in South Korea and thereby to gain insight into effective ways to improve relatively low fertility and unfavorable workplace conditions for women of childbearing age. This study used the merged data(1st-5th waves) from Korean Longitudinal Survey of Women and Families (KLoWF), which were measured by the Korean Women's Development Institute. With 1,020 married business women, cross tab and binary logistic regression were conducted to determine which factors were significantly associated with the first childbearing decisions.

  • The purpose of this study is to explore the role of Home Economics Education for low fertility Aged Society. Hence home economics educational contents for low fertility Aged Society was estsblished extracting the contents from both Revised 2007 Home Economics Curriculum and government. policy for low fertility Aged Society. Also home economics educational contents for low fertility Aged Society("Home Economics Class for both parents and Children") implemented in Healthy Family Support Center. The main results of the study are as follows. Firstly, Home Economics Education for low fertility Aged Society should be emphasized with the contents such as marriage of one's choice, family life reinforcement, healthy family culture and neighborhood living together. Secondly, the goal of home economics education is very similar to the action plans of Saeromaji Project 2010 which are 'social responsibility reinforcement for marriage, birth and child rearing', 'balancing family and work', 'family-friendly culture' and 'security for the aged with health and care'. It has also much in common with the project plans by Seoul Metropolitan Office of Education 'family-friendly culture and filial duty education reinforcement', 'school education reinforcement regarding Low Fertility-Aged Society' and 'values education reinforcement for gender equality society'. Thirdly, "Home Economics Class for both parents and Children" applied in Healthy Family Support Center in Jung-gu, Seoul. This ensures home economic education can play a leading role in the social education filed.

  • This study was attempted to identify the effect of university students on their childbirth willingness, provide it as basic data for childbirth encouragement policies, and contribute to the composition of educational data. Multiple regression analysis of data from 195 university students using the SPSS/WIN 22.0 program. The more conservative the view of marriage (r=.142, p<.05) and the higher the degree of awareness of childbirth encouragement policy(r=.258, p<.01), the more significant the correlation was childbearing willingness. The conservative marriage values, youth job policies, and the degree of recognition of work-family balance support influenced the childbearing willingness, and these variables explained the childbearing willingness 9.2%.

  • This study examines the causal mechanisms of low fertility and regional differentials in Korea. Utilizing the 2005 census and the 2005 vital statistics, and labor statistics at the regional level, major variables were calculated for administrative units of 234 'Gu's, 'Si's and 'Gun's. Gender equity orientation, labor market insecurity and family formation were hypothesized as key factors of recent decline in Korean fertility. This study first presents four maps of gender equity orientation, labor market insecurity, family formation and fertility. Then ANOVA and path analysis were carried out in an effort to generalize the causal mechanisms. Results of analysis reveal that gender equity orientation has played a central role in the second fertility transition in Korea. In metropolitan regions, however, labor market insecurity is found to have a significant influence on the level of family formation and fertility. Family formation also turns out to be an important intermediate variable of fertility.

  • 본 연구는 중국의 3개지역 (Hebei, Shaanxi, Shanghai)에서 한 자녀가족정책이 둘째 및 셋째 아이의 출산에 미치는 영향을 헤져드(Hazard) 모델을 이용하여 분석하고 있다. 특히, 그 정책효과의 도시와 농촌간의 격차, 현재자녀의 성구조에 따른 격차의 연구에 중점을 두고 있다. 연구자료는 1985년에 완료된 제 1단계 중국의 출산력 심층조사 (In-Depth Fertility Survey in China)를 이용하였다. 이 분석은 해져드 모델에서 각 시점의 한 자녀정책 전인지 후인지를 나타내는 시간에 따른 변동변수(time-varying variable)를 설명변수중의 하나로 포함시키고 그와 더불어 그 변수와 도시/농촌 주거여부를 나타내는 변수와의 혼합변수 (Interactive term) 및 현존자녀의 성구조와의 혼합변수를 포함하므로써 가능하게 된다. 또한, 자녀의 사망력이 차후 출산력에 미치는 영향을 비슷한 방법으로 분석하였다. 연구결과로는 첫째, 둘째 및 셋째 아이를 출산할 확률에 있어서 도시와 농촌격차가 한 자녀정책 실시 이후 더욱 커졌다는 사실이다. 이러한 결과는 부모가 생각하는 자녀의 가치가 도시에서 더 많이 저하했음을 제시하거나 정부의 한 자녀정책이 도시에서 더욱더 엄격히 집행되고 있음을 시사하고 있다. 둘째, Hebei와 Shanghai에서는 남아가 없는 부부가 남아를 가진 부부보다 둘째 또는 셋째아이를 가질 확률이 훨씬 높게 나타났다. 한편, Shanghai에서는 한 자녀정책 이후 둘째아이의 출산률이 첫째아이의 성에 관계없이 매우 낮았다. 이는 전통적으로 내려오는 남아선호 성향이 아직 농촌지역에서는 강하게 영향을 미치고 있지만 도시지역에서는 강력한 정책집행이 이를 억누르고 있음을 시사하고 있다. 하지만 Shanghai에서도 첫째아이가 사망한 경우 그 아이가 남아였으면 죽은아이가 여아이였을 경우보다 둘째아이의 출산이 훨씬 더 빠르게 나타나고 있음을 볼 때 도시에서도 여전히 남아선호 성향이 잠재하고 있음을 간접적으로 보여주고 있다.
