현재 폐교된 학교의 데이터들과 후에 폐교될 위험이 있는 학교들의 데이터를 활용하여, 민간, 국가기관 모두에 유용한 데이터를 제공할 수 있는 시스템을 구축하였다. 사용한 데이터로는 22년도 출산율, 14년도 출산율, 지역별 폐교 이용 현황, 전체 폐교 데이터, 현재 학교 인원 현황에 관한 자료를 활용했다. 이같은 데이터를 통해 현재 운영되고 있는 학교 중 폐교 위험의 범주 안에 들어가 있는 학교를 가중치 전략으로 추출할 수 있게 만들었다. 시스템 예측 결과, 현재까지 폐교된 학교들보다 더 많은 학교들이 폐교위기에 처해있고, 더 많은 학교들이 폐교될 것으로 예상된다. 급감하는 출산률을 보아 폐교되는 추세를 줄일 수 없다. 따라서 정부 차원에서 폐교 대부와 경매, 폐교활용 조건을 완화시키고, 학교 건물들을 대책없이 방치시키는 일을 미리 대비해야 한다고 사료된다.

This study examines how individual, familial, and social factors are associated with persistent very low fertility in Busan Metropolitan City and contemplates family-friendly environments and social strategies for fertility increase. Fertility decline in Busan Metropolitan City recorded the lowest birth rate nationwide recent years among metropolitan cities and provinces in Korea. Birthrates are low partly because of multiple factors such as high age at childbearing and at marriage, decline in marriage, high divorce rate, the phenomena of marriage avoidance among unmarried women, traditional gender role attitude of men, low domestic work participation of husbands among dual career couples, low marital satisfaction and family life satisfaction, abortion, and more broader attiributes such as family policy, availability of childcare, education expenses, and family-friendlyness of a society. In addition, women of dual career couples in Busan strained from domestic work overload under traditional norms of gender role, and marital satisfaction recorded below average nationwide along with espeacially low marital satisfaction of wives compared to that of husbands. Major aspects of implications and considerations for higher birth rate and family friendly policy in Busan are discussed.

The purpose of this study was to understand the relationship between fertility rate and the women's employment experience in household having one child, to observe the effects of related personal factor, family factor and social factor. The sample population included 276 married women in the reproductive ages(25$\~$45 years old) which are no additional pregnant or delivery after the first child birth. The major findings of the research are as follows: First, it shows some relevance between the plan of child birth and the experience of women for employment. Specially, the married women experiencing discontinuance of employment become to have a plan and motivation about the second child birth. Second, the motivations of child birth in woman of lower fertility household are related to her age, the existence of young child, and the education. Thirdly, as a result of Logit analysis, they have the plan to deliver additionally after first child birth in case of younger age and higher educational achievement than Master degree.

The fertility rate of Korea has rapidly decreased to the lowest in the World. The fertility rate below replacement fertility level might result in many social problems. First, this study investigated the cause of low fertility rate. Second, the theories of the relationship between fertility rate and women's employment were reviewed. The previous studies suggested that the fertility rate was not always related to women's employment negatively and there was mediating factors between them. Third, the various factors that mediated the negative relationship between fertility rate and women's employment were described in personal, family and social levels. Finally, this study suggested the policies and strategies to solve the low fertility rate problem in Korea.

This paper implemented a method to predict the fertility rate, mortality rate, and international migration rate using the R program, which has been widely used in recent years, that calculates population projection by substituting the results into the Leslie matrix. In particular, the generalization log gamma model for the fertility rate by Kaneko (2003), LC-ER model for mortality rate by Li et al. (2013), and functional data model for international migration rates proposed by Ramsay and Silverman (2005) and Hyndman and Booth (2008), Hyndman et al. (2013) can be directly demonstrated with R programs. Demography and bayesPop have been introduced as a representative demographic package implemented in R; however, it can be analyzed only for data uploaded to Human Mortality Database (HMD) and Human Fertility Database (HFD) with data changes and modifications requiring application of other data. In particular, in Korea, there is a limitation in applying this package because it is provided only for short-term data in HMD. This paper introduces an R program that can reflect this situation and the different patterns of low fertility, aging, migration of domestic and foreigners in Korea, and derives a population projection for the year 2117.

This study is intended to examine (l)whether the value of son-for example, old age security and succession of family lineage- causing son preference in the traditional society can be explained at the individual level, (2)whether women without son in the son preference country continue her childbearing until having at least one son or give up the desire of having a son at a certain level. To accomplish these purposes, the 1974 Korean National Fertility Survey data are analyzed by the quadratic hazard models controlling unobserved heterogeneity. Unlike ordinary regression model, even omitted variables that affect hazard rates and are uncorrelated with the included independent variables can distort the parameter estimates in the hazard model. Therefore the nonparametric maximum likelihood estimator(NPMLE) of a mixing distribution developed by Heckman and Singer is used to control unobserved heterogeneity. Based on the statistical result in this study, the value of son causing son preference is determined at the societal level, not at the individual level. And Korean women without a son did not continue endlessly childbearing during child bearing ages until having a son. In general, they gave up the desire having a son when she had born six daughters continuously. Thus, 30-40 years ago, the number of daughters that women without a son giving up the desire of son was six, which is about the level of total fertility rate during 1960s. In these days, we can often see many women who have only two or three daughters and do not any son. This means that the level of giving up the desire of son, which is one factor representing the strength of son preference, becomes lower. If the strength of son preference did not become much weaker, then the fertility rates in Korea could not reach the below replacement level.

This paper examines the interplay among changes in socioeconomic conditions, population policies, and fertility decline during $1960{\sim}2000$ in South Korea. Period-parity-progression-ratios (PPPR) are calculated using 2% samples of Population Census with the implied distribution of completed family size. The total fertility rate based on PPPR declined from 5.21 in 1960 to 2.76 in 1980, and 1.69 in 2000. The family planning programs were successful in meeting the needs of families that wanted to prevent further childbearing after having achieved the desired family size during $1960{\sim}1970$. The 1980s mark two important landmarks: achievement of replacement fertility and emergence of high sex ratio at birth. In the 1990s the "quality and welfare" approach was emphasized. In 2000s, South Korea's fertility is one of the lowest in the world. In response to this, in 2005, the Government adopted a new population policy with the goal of increasing the total fertility level to 1.6 by 2010. The results of this study indicate that proportion of women who would have no children at all throughout their reproductive life span increased substantially from 10% in 1995 to 16% in 2000, with a sharp increase since 1997. Thus, pro-natal programs need to address the problems associated with marriage and having the first child. Towards that, it is important that work and family life become more compatible.

The issues on education as a human capital formation in recent years have been focused for all of the countries with emerging of the knowledge-based economy. The present study compared and analyzed the relationships between the educational investment and national economic growth of ten non-English-speaking OECD countries during 1970-2008, using Ordinary Least Square (OLS) and Seemingly Unrelated Regression Estimation (SURE) as the main analytical methods. Findings indicate that educational investment, R&D investment, and fertility rate were statistically significant in the estimation of the variables related to the human capital formation, and these elements had also positive influence on the national economic growth. The most salient factor was the fertility rate, and the R&D investment and educational investment appeared as the next factors in the national economic growth. In particular, the dimensions in the coefficient of the fertility rate showed 1.8 times of the R&D and 3.5 times of the educational investment, respectively. These results imply that educational investment, R&D investment, and the policies which promote fertility rate should be taken into account for the continuous economic growth of each country.

The total fertility rate of our nation has been in the world's lowest level with constant falling since it reached an all-time low in 1983. The increase in economic participation of women, difficulties to balance work and family life, and traditional gender role and family norms in our society have been blamed for causing low birth rates. In addition, the current economic recession and increased polarization of wealth make it more difficult for working families to balance work and family life, resulting in lowering fertility rates. The Korean government has recently prepared the second five-year basic plan(2011-2015) to deal with low fertility and population ageing. The basic plan aims at providing support for working families in balancing work and family life and helping people ease the burden of marriage, childbirth, and raising their children. The work-family balance policies based on gender equality will do much to increase fertility rates in the future. In this context, this study examined current status and problems of balancing work and family life in our society, the Korean government and corporate policies for work-family balance, and the effects of policies on childbirth. Suggestions for future directions are presented.
