Demographic transition and population aging in Korea
Korea Journal of Population and Development
|July 1, 1996
Summary
South Korea
Area of Science:
- Demography
- Sociology
- Gerontology
Background:
- South Korea is undergoing a rapid demographic transition.
- This transition involves swift declines in mortality and fertility rates.
- Consequently, the nation faces an accelerated population aging process.
Purpose of the Study:
- To analyze population aging in South Korea.
- To examine the link between demographic transition and aging.
- To investigate shifts in elderly living arrangements.
Main Methods:
- Analysis of demographic transition trends in South Korea.
- Examination of population aging speed and projections.
- Statistical analysis of changes in elderly household composition.
Main Results:
- South Korea's population aging is among the fastest globally.
- Elderly living arrangements are shifting significantly.
- Increases observed in the proportion of elderly living alone or with a spouse only.
Conclusions:
- Rapid population aging in South Korea is driven by demographic transition.
- These demographic shifts necessitate adaptation in social structures.
- Understanding changing elderly living arrangements is crucial for policy development.

02:31Phase Transitions
23.3K
Whether solid, liquid, or gas, a substance's state depends on the order and arrangement of its particles (atoms, molecules, or ions). Particles in the solid pack closely together, generally in a pattern. The particles vibrate about their fixed positions but do not move or squeeze past their neighbors. In liquids, although the particles are closely spaced, they are randomly arranged. The position of the particles are not fixed—that is, they are free to move past their neighbors to...

02:58Properties of Transition Metals
30.0K
Transition metals are defined as those elements that have partially filled d orbitals. As shown in Figure 1, the d-block elements in groups 3–12 are transition elements. The f-block elements, also called inner transition metals (the lanthanides and actinides), also meet this criterion because the d orbital is partially occupied before the f orbitals.

01:58Cooperative Allosteric Transitions
8.8K
Cooperative allosteric transitions can occur in multimeric proteins, where each subunit of the protein has its own ligand-binding site. When a ligand binds to any of these subunits, it triggers a conformational change that affects the binding sites in the other subunits; this can change the affinity of the other sites for their respective ligands. The ability of the protein to change the shape of its binding site is attributed to the presence of a mix of flexible and stable segments in the...

02:04Conservation of Small Populations
17.4K
Small population sizes put a species at extreme risk of extinction due to a lack of variation, and a consequent decrease in adaptability. This weakens the chances of survival under pressures such as climate change, competition from other species, or new diseases. Large populations are more likely to survive pressures such as these, as such populations are more likely to harbor individuals that have genetic variants that are adaptive under new stresses. Small populations are much less...

01:25What is Population Genetics?
64.9K
A population is composed of members of the same species that simultaneously live and interact in the same area. When individuals in a population breed, they pass down their genes to their offspring. Many of these genes are polymorphic, meaning that they occur in multiple variants. Such variations of a gene are referred to as alleles. The collective set of all the alleles within a population is known as the gene pool.

02:39Phase Transitions: Vaporization and Condensation
21.5K
The physical form of a substance changes on changing its temperature. For example, raising the temperature of a liquid causes the liquid to vaporize (convert into vapor). The process is called vaporization—a surface phenomenon. Vaporization occurs when the thermal motion of the molecules overcome the intermolecular forces, and the molecules (at the surface) escape into the gaseous state. When a liquid vaporizes in a closed container, gas molecules cannot escape. As these gas phase molecules...
