Security, nationalism and the pursuit of nuclear weapons and missiles: The South Korean case, 1970-82

South Korea decided to develop nuclear weapons and surface-to-surface missiles in the early 1970s. The Park Chung-hee administration made the decision because of its concern about a complete withdrawal of US forces from Korea following the Nixon Doctrine. Simultaneously, increasing nationalism within the administration, caused by its tumultuous relations with the United States, further strengthened such pursuits. Later, when faced with the US threat to withdraw security and economic assistance, the administration slowed down active development of nuclear weapons in 1976, but it continued missile development. However, the Chun Doo-hwan administration, inaugurated in 1980 after military coup and massacre, froze all weapons-related nuclear research and the missile programme. The Chun regime made such a change because it needed the support of the US to make up for its weakness in legitimacy and because the Reagan administration provided a solid defence commitment to South Korea.     

Eastern Mediterranean Gas Discoveries: Local and Global Impact

The ongoing discoveries of natural-gas reserves in the eastern Mediterranean region significantly affect international relations. Since their viability has been increasingly confirmed, they have attracted public attention in the international energy market. Focusing on current gas production and trading in the Middle East, this paper studies the anticipated impact of gas production in the sea on geopolitical relations in the Middle East and investigates how these results may change the geoeconomic strategies of global energy-market players as well as nearby countries. In addition, our analyses provide comprehensive insights into the evolution of gas discoveries in the Eastern Mediterranean.     

Molecular Identification of Necrophagous Dermestes Species in South Korea Using Cytochrome c Oxidase Subunit I Nucleotide Sequences (Genus Dermestes)

Species identification of necrophagous insects found on a dead body is an essential key in applying medicolegal entomology to the estimation of postmortem interval (PMI). Due to limited morphological identification of insect evidence, several studies have identified species using molecular information such as DNA markers. While considerable cytochrome c oxidase subunit I (COI) gene sequence data of necrophagous fly species have been collected and annotated, those of necrophagous beetle species have not. Since necrophagous beetles such as Dermestes species have a larval period longer than that of flies, beetles are useful in even the late decomposition phase in estimating minimum PMI. To obtain the full-length COI gene sequences of six Dermestes species collected from South Korea, we designed primers for polymerase chain reaction amplification and sequencing. The obtained full COI nucleotide sequences were used for performing phylogenic analysis and comparison with previously reported sequences. The results demonstrated that the COI gene sequences could be used to identify forensically important Dermestes species in South Korea.     

Simplified Direct PCR Method for Reference Buccal Samples Using a Non-FTA Card by Omitting the Pretreatment Step

When using non-FTA cards in commercial multiplex STR kits for direct PCR, pretreatment steps with specific buffers are recommended. Here, we designed a rapid direct PCR method utilizing a non-FTA card, Oral Cell Sampling Kit, by omitting the pretreatment step involving Prep-n-Go™ Buffer, and it showed compatibility with the GlobalFiler™ Express PCR Amplification Kit, GlobalFiler™ PCR Amplification Kit, and PowerPlex^® Fusion system. To optimize the PCR conditions, we tested the method with different final PCR volumes and cycles. Finally, we conducted a performance test using 50 Korean buccal samples and confirmed the high performance of the method, detecting more than 90% of the samples with full profiles when using GlobalFiler™ PCR Amplification Kit and PowerPlex^® Fusion system at 29 cycles in a 10 μL final PCR volume. Thus, we report a simple direct PCR set-up to analyze reference samples collected using a non-FTA card manufactured in Korea.
