Demography has grown as an independent academic discipline in Korea during past 30 years by describing and examining changes of population components such as fertility, mortality, migration, and census, and the "Population Association of Korea" stands on the midst of the growth. High fertility of the 1960s and 70s, which was considered as a hurdle of economic growth, particularly boosted the prosper of demography in Korea by inviting a number of non-demographers as well as demographers to population-related research projects. However, as fertility gradually decreases and becomes no-threat anymore beginning the early 1990s, social interests in demography has withered to lose its academic soils in Korea. A recent phenomenon of the lowest low fertility has revived social need and interest in demography. Unfortunately, once curtailed capacity of Korean demography is not sufficient enough to provide academic and/or practical resources now. This research is conducted to cerebrate the 30th anniversary of "Population Association of Korea" and to seek ways to cultivate academic soils again and to rebuild the capacity of demography in Korea. To do this, this research examines the causes of current struggles of Korean demography by comparing its academic environments with that of America, and offers suggestions for its brighter future.

The methodology in historical demography comprises the three core areas the family reconstitution method at the Institut National d' Ftudes Demographiques(I.N.E.D), the back projection at the Cambridge Group for the History of PopuJation and Social Struc-ture(HPSS). and the household-pattern analysis at the Cambridge Group and at the California Institute of Technology. The paper presents an outline of the family reconstitu-tion method and discusses the problems, both theoretical and methodological, arising from the problematic back projection vis-a-vis the usual inverse projection developed by Ronald D. Lee at Berkeley. Recent developments in the tield of the generalized inverse projection method designed 10 supplement the defects in the back projection and the inverse projection are presented. and for ease of explanation of the parish register data for the family reconstitution form (FRE). pre-modern Korean household register data are presented along with the parish register data of England and Wales that constitute the backbone of historical demography in pre-modern Europe. Possibilities of exploring the household pattern analysis method based on the Laslett-Hammel classification scheme for the mid-eighteenth-century Korean household register data are suggested.

This study investigates the spatial patterns of distributed population in terms of population density, age structure, sex structure and family structure in Chou (smallest political city boundaries) of seven cities of Kitakawachi region. This displays the population dynamics of those cities from 1955 to 1995. It demonstrates how the populations of the cities are distributed with topography and with respect to the train stations. The demographic characteristics of the cities are visualized utilizing Arc View GIS capabilities with new visualizing technique in 3D environment based on data from Pasco Digital Map 2000.

The central theme of Habital heterogeneity is to provide animals with habital complexity or structural diversity and to allow resource partitioning among individuals. In turn, the leads to population stability because prey can escape more easily with more hiding places causing less population fluctuation. Species diversity is characterized due to more potential niches both horizontally and verticall. Empirically, in homogeneous habitats population was less abundant, reproduction and survival were lower, spacing behavior, competition and dispersal were higher than in heterogeneous habitats. The results imply that diversity and conservation of species can be maintained through providing heterogeneous habitats.

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.

While we go through a rapid change in society, family types composing social relationship underwent lots of changes. Recently the range of family is included not only families on the basis of blood relationship but also single family, a one-parent family and non-blood relationship family. Now we need not unified types of housing but social integrated housing models responding to family diversity. The purpose of this study is that examine family diversity through social statistics and demography and grasp the current housing types responding to family diversity. The features of family diversity are reducing the number of family member and turning up a unformal family type. At the social statistics and demography in 2005, the number of family member is only 2.9 people per family. Due to decline of birth rate and change of marriage consciousness, various family types appear and increase such as single family, a one-parent family and non-blood relationship family. But there is lack of housing types responding to such family diversity. This study will be a basic research to develop social integrated housing models responding to family diversity. Housing must be sensitive to change of family type, so it responds our needs based on thorough understanding on various housing life.

인구가 성장한다는 사실과 함께 인구가 지역적으로 이동하는 현상은 사회과학에 있어서 중요한 연구대상이 되어왔다. 전통적으로 인구의 동학적 측면은 사회학의 주된 연구대상이 되어왔으며 근래에는 인구학(demography)이라는 새로운 독립과학의 분과로서 더욱 이 분야에서의 연구의 심도와 폭이 확대되었다. 그러나 인구의 동학적 측면을 인간의 경제형태의 일환으로 관찰할 수 있는 기회와 가능성이 점차적으로 크게 부각되자 전통적인 경제이론을 적용함으로써 이러한 문제를 분석/구명하고자 하는 동향이 나타나게 되었다. 특히 인구의 단기적 지역간 이동이 경제사회의 질적인 변화와 이에 따르는 산업구조간의 노동력 균형의 재조정에 따라 원인되고 있다는 사실은 인구의 동학적 측면에 경제학적 분석이 당연히 이루어져야 한다는 요구를 초래시키기에 이르렀다.
