Abstract North Korea has made significant strides in its attempt to acquire a strategic nuclear deterrent. In 2017, it tested intercontinental ballistic missiles (ICBMs) and completed series of test explosions. These may provide with the technical foundation deploy nuclear-armed ICBM capable striking United States. The Ground-based Midcourse Defense (GMD) missile defense system is intended dete...

enemy” in the minds of South Korean conservatives who returned to power in 2008 rather than a real general in the 1950s. This film differs from post-1990 war films by clearly establishing the fact that the Korean War was an invasion of the South by the North, not unlike Cold War anticommunist films, but is more anti-North Korean than anticommunist by presuming that the “enemy” is the Supreme Le...

In this paper, I try to identify and explain how certain factors are obstructing the reunification of North and South Korea. This paper refers to eight published articles that touch on diverse negative factors which affect the Korean reunification. There are many factors to consider, such as political interests, conflicting views of the North and the South toward the reunification, and the long...

BACKGROUND Understanding the health status of North Korean refugees (NKRs), and changes in health during the resettlement process, is important from both the humanitarian standpoint and the scientific perspective. The NOrth Korean Refugee health iN South Korea (NORNS) study aims to document the health status and health determinants of North Korean refugees, to observe various health outcomes as...

DNA barcoding, an inventory of DNA sequences from a standardized genomic region, provides a bio-barcode for identifying and discovering species. Several recent studies suggest that the sequence diversity in a 648 bp region of the mitochondrial gene for cytochrome c oxi- dase I (COI) might serve as a DNA barcode for identify- ing animal species such as North American birds, in- sects and fishes....

Two strains of Azadinium poporum, one from the Korean West coast and the other from the North Sea, were mass cultured for isolation of new azaspiracids. Approximately 0.9 mg of pure AZA-36 (1) and 1.3 mg of pure AZA-37 (2) were isolated from the Korean (870 L) and North Sea (120 L) strains, respectively. The structures were determined to be 3-hydroxy-8-methyl-39-demethyl-azaspiracid-1 (1) and 3...

Underground nuclear explosions (UNEs) can induce acoustic-gravity waves, which disturb the ionosphere and initiate traveling ionospheric disturbances (TIDs). In this paper, we employ a multi-step and multi-order numerical difference method with dual-frequency GPS data to detect ionospheric disturbances triggered by the North Korean UNE on 25 May 2009. Several International GNSS Service (IGS) st...
