In recent years, the global geopolitical landscape has been significantly influenced by nations asserting dominance in key sectors, including finance, intellectual property, and military industries. This ascendancy allows states to dictate terms and wield substantial impact on the world order. In particular, China has emerged as a pivotal player, strategically utilizing innovation and economic prowess to reshape international relations. This research examines China’s role in redefining global power dynamics, particularly within Africa, while evaluating the effectiveness and criticisms of its “soft power” strategies. China’s robust presence in critical sectors such as finance, intellectual property, and military industries underscores the correlation between leadership in these domains and global influence. The country’s economic and technological prowess has positioned it as a formidable player, enabling it to exert significant control over international rules and norms. The ramifications of such dominance transcend mere economic power, influencing diplomatic relations and shaping the international order.

On the international political stage of the 21st century, the strategic rivalry between China and the United States is one of the most captivating focal points. As two major global powers, China and the United States, their competition and cooperation across multiple domains have profound implications for the global political and economic landscape. The historical evolution of Sino-U.S. relations provides us with key insights into the understanding of the current strategic rivalry. Within the realm of hard power, the economic and technological rivalry between China and the United States is intensifying, engendering notable frictions within areas such as economics and technology. These frictions reverberate through their interactions, influencing their positions and interests on the global stage. However, the role of soft power in the context of Sino-American relations cannot be understated. The United States has persistently exported its values of democracy and freedom, whereas China emphasizes the principles of peaceful development and shared prosperity. The strategic rivalry between China and the United States is an intricate, multifaceted issue that poses significant challenges. To effectively address this complexity, China must employ a comprehensive array of strategies and measures to ensure its enduring stability and sustained development in the ever-evolving global landscape.

Soft magnetic powder materials are used throughout industries such as motors and power converters. When manufacturing Fe-based soft magnetic composites, the size and shape of the soft magnetic powder and the microstructure in the powder are closely related to the magnetic properties. In this study, Fe-Si-Al-P alloy powders were manufactured using various manufacturing process parameter sets, and the process parameters of the vacuum induction melt gas atomization process were set as melt temperature, atomization gas pressure, and gas flow rate. Process variable data that records are converted into 6 types of data for each powder recovery section. Process variable data that recorded minute changes were converted into 6 types of data and used as input variables. As output variables, a total of 6 types were designated by measuring the particle size, flowability, apparent density, and sphericity of the manufactured powders according to the process variable conditions. The sensitivity of the input and output variables was analyzed through the Pearson correlation coefficient, and a total of 6 powder characteristics were analyzed by artificial neural network model. The prediction results were compared with the results through linear regression analysis and response surface methodology, respectively.

본 논문은 한국 드라마 <태양의 후예>를 분석하여 홍보가 한 나라 의 소프트 파워 전략에 어떻게 작용하는지, 그리고 문화와 이데올로기 의 전파가 전 세계 매체 환경에서 어떻게 전파되는지를 탐구하였다. 우 선 국가 주도의 소프트 파워를 홍보에 접목한 이론적인 틀을 제시하였 다. 그리고 한국 영화와 드라마의 홍보 역사를 정리하였다. 이어서 <태양의 후예>는 소프트 파워가 갖춰진 한류 드라마이자 홍보 드라마 임을 논의하였다. 끝으로 소프트 파워, 홍보, 한류 대중문화 사이의 관 계, 국가가 대중문화의 생산과 보급에 어떻게 참여하는지, 그리고 이 과정에서 소프트 파워가 어떻게 적용되는지를 제시하였다.
