  • This paper is to analyse conflict between the US and China over the South China Sea and Korea's responses. To this end the paper is composed of 6 chapters titled instruction; the current status of South China Sea sovereignty disputes; changes in US and Chinese maritime security strategies and the strategic values of the South China Sea; key issues and future prospects for US-China conflicts in the South China Sea; South Korea's security and diplomatic responses; and conclusion. The recent East Asian maritime security issue has evolved into a global issue of supremacy between the US and China, beyond conflicts over territorial disputes and demarcation among the countries in the region. China is pursuing offensive ocean policy to expand economic growth. The core of the maritime order that the United States intends to pursue is the freedom of navigation in the oceans and the maintenance of maritime access. China is making artificial islands in the South China Sea, claiming the sovereignty of these islands, building strategic bases in East Asia, and securing routes. The United States has developed several "Freedom of Navigation Operations" to neutralize the declaration of the territorial sea surrounding Chinese artificial islands. We can not be free from marine conflicts in the South China Sea and the East China Sea. Regarding the South China Sea dispute, it is expected that the strategic competition and conflict between the two countries will intensify due to China's failure to make concessions of core interests and adherence to the US compliance with international norms. In the midst of conflict over the South China Sea, we need a harmonious balance between our alliance security and economic diplomacy. We must continue our efforts to strengthen the ROK-US alliance but not to make China an enemy. Considering the significant impacts of the oceans on the survival and prosperity of the nation, we must continue to develop our interest in the oceans, appropriate investments and tactical strategies.

  • 본 논문은 대한민국 서해와 남해에서의 거리에 따른 성능분석을 위해 실해역 측정을 했다. 서해와 남해 선박의 거리와 전송율 관점에서 측정된 실해역 데이터를 기반으로 데이터 반복 전송 횟수와 파일럿 심볼 배치 간격 파라미터를 조절하여 서해와 남해 성능 비교를 통해 수중OFDM 시스템을 성능을 분석하였다. 결론으로는 전송율과 거리에서 남해의 성능을 비교했을 때 파라미터가 같은 조건에서 남해 5km, 서해 1km 거리에서 BER성능이 남해가 성능이 비슷하였으며, 남해 10km,서해 3km에서 파일럿 심볼의 배치간격을 (𝚫f, 𝚫t) = (6, 3)의 심볼과 PRB가 반복되는 (Rf, Rt) = (2, 1)에서 남해는 1078.92bit/s 서해는 1384.57bit/s으로 전송율관점에서도 남해에서 장거리에서 높은 데이터를 보낼 수 있는걸 확인하였다
