Samsung countered that only an accumulated amount of 0.05 grams of silver is released per machine, per year, while the released silver-ions quickly bind to non-nano-sized structures in the water. This then raises the question of what structures Samsung thinks these nanoparticles will bind to that they will not later come into contact with marine life. In Silver Nanotechnologies and

President Park Geun-hye's administration was formally accused of corruption, bribery, and influence-peddling for the involvement of close friend Choi Soon-sil in state affairs. There followed

7854-453: The Tang dynasty. Goguryeo was alternately called Mahan by the Tang dynasty, as evidenced by a Tang document that called Goguryeo generals "Mahan leaders" ( 마한추장 ; 馬韓酋長 ; Mahan Choojang ) in 645.

Its first kingdom was noted in Chinese records in the early 7th century BCE. After

9758-475: The environment. Unchecked industrialization and urban development have resulted in deforestation and the ongoing destruction of wetlands such as the Songdo Tidal Flat. However, there have been recent efforts to balance these problems, including a government run $ 84 billion five-year green growth project that aims to boost energy efficiency and green technology. The green-based economic strategy

9877-406: The establishment of Goguryeo, its early history is well attested archaeologically: the first and second capital cities , Jolbon and Gungnae city, are located in and around today's Ji'an, Jilin .

14161-513: Was the only recognizable kind of pottery production from the end of the 4th century A.D. At the same time the production centers for pottery became highly centralized and vessels became standardized. Centralisation and elite control of production is demonstrated by the results of the archaeological excavations at Songok-dong and Mulcheon-ni in Gyeongju . These sites are part of what was an interconnected and sprawling ancient industrial complex on
